Objective To investigate inpatient disease constitution in Traditional Chinese Medicine (TCM) Hospital of Xinjiang Uygur Autonomous Region from 2008 to 2010, in order to provide baseline data for medicine allocation of hospitals in western China and development of TCM hospitals. Methods A questionnaire combined with a subject interview was carried out, and the case records of inpatients from 2008 to 2010 were collected. The diseases in discharge records were classified according to International Classification of Diseases (ICD-10) based on the first diagnosis. Data including general information of the inpatients, discharge diagnosis etc. were rearranged and analyzed by Excel software. Results a) The top four systematic diseases seen commonly from 2008 to 2010 were as follows: circulatory system diseases, musculoskeletal system and connective tissue diseases, respiratory system diseases and digestive system diseases. The top four single diseases were hypertension, intervertebral disc disease, diabetes, bronchitis, emphysema and other chronic obstructive pulmonary diseases. Respiratory system diseases ranked the third in 2009 and 2010 from the fourth in 2008, and circulatory system diseases had ranked the first during the past three years; b) The following diseases as hypertension, bronchial emphysema and other chronic obstructive pulmonary diseases, diabetes, fractures, airway (bronchus, lung) cancer, and viral hepatitis were commonly seen in males rather than in females. By contrast, intervertebral disc disease, gallstone disease and cholecystitis, and anemia were commonly seen in females; and c) Hypertension was commonly seen in the aged above 60 years old; intervertebral disc disease mainly focused on the patients at the age of 15 to 59; and bronchial emphysema and other chronic obstructive pulmonary diseases, airway (bronchus, lung) cancer involved in the patients who were mostly over 60 years old. Conclusion a) The top four systematic diseases seen commonly from 2008to 2010 are as follows: circulatory system diseases, musculoskeletal system and connective tissue diseases, respiratory system diseases and digestive system diseases. The top four single diseases are hypertension, intervertebral disc disease, diabetes, bronchitis, emphysema and other chronic obstructive pulmonary diseases. So these diseases should be taken into well consideration when making development plans by hospital and complementing essential drugs list by local development; b) Chronic diseases become the main disease for troubling Xinjiang population; and c) Male and female are susceptible to different diseases which should be rationally avoided in order to prevent the induced occurrence.

Objective To systematically evaluate the effectiveness of N-acetylcysteine (NAC) combined with low-dose glucocorticoid for patients with idiopathic pulmonary fibrosis (IPF). Methods Such databases as The Cochrane Library (Issue 12, 2012), EMbase (January 1974 to July 2012), PubMed (January 1966 to July 2012), CHEST (January 1995 to July 2012), CNKI (January 1994 to July 2012), CBM (January 1978 to July 2012), VIP (January 1989 to July 2012) and WanFang Data (January 1995 to July 2012) were searched to collect the randomized controlled trials (RCTs) about NAC combined with low-dose glucocorticoid versus glucocorticoid alone for IPF patients. Two reviewers independently screened the literature according to the inclusion and exclusion criteria, extracted the data, and assessed the quality, and then the meta-analysis was performed using RevMan 5.1 software. Results A total of seven RCTs including 264 IPF patients were included. The results of meta-analysis demonstrated that, compared with the glucocorticoid used alone, a) NAC combined with low-dose glucocorticoid could significantly improve PaO2 (SMD=0.82 mmHg, 95%CI 0.30 to 1.35, P=0.002) and DLco (SMD=0.59 mmHg, 95%CI 0.16 to 1.03, P=0.008) with a significant difference. b) NAC combined with low-dose glucocorticoid could significantly improve all clinical symptoms (RR=1.56, 95%CI 1.26 to 1.92, Plt;0.000 1). Conclusion NAC combined with low-dose glucocorticoid for IPF patients can significantly improve PaO2, DLco, and the clinical symptoms such as cough, difficulty breathing after activities, cyanosis, and Velcro rales. Due to the quantity and quality limitation of included studies, this conclusion still needs to be further proved by more high quality and double blind RCTs.
Objective To employ spinal virtual surgery system (SVSS) for preoperative planning of thoracolumbar pedicle screw fixation, and to establ ish the measurement method for pedicle screw-related parameters. Methods Eight thoracicand lumbar spine specimens (T11-L3) were selected. First of all, SVSS was used for the preoperative planning of pedicle screw and the parameters of both sides of pedicle were measured in every vertebral segment, including angle of axial view (Aa), angle of sagittal view (As), x-direction entrance (XE), total pedicle length of axial view (TLa), total pedicle length of sagittal view (TLs), pedicle height (PH), pedicle width (PW), and pedicle spongy width (PSW). Then the corresponding parameters of the right and left pedicle screws of the specimens were measured actually. Finally, its accuracy was verified by comparing the data by virtual measurement and actual measurement. Results There was no significant difference in the parameters of virtual measurement (Aa, As, TLa, TLs, XE, PW, PSW, and PH) and actual measurement (Aa, As, TLa, XE, PW, PSW, and PH) between the right and left sides (P gt; 0.05). Except XE of the L3 vertebral segment and PSW of T11 and T12 vertebral segments (P lt; 0.05), the differences in other parameters of other segments were not significant (P gt; 0.05). Conclusion After statistical analysis and comparison, the feasibil ity of preoperative planning of thoracolumbar pedicle screw fixation and the accuracy of the measurement of the SVSS is verified.
ObjectiveThis study aimed to compare the effects of aerobic training, resistance training, and aerobic training combined with resistance training on blood lipid levels for patients with hypertension using network meta-analysis. MethodsWe searched the CNKI, VIP, WanFang Data, PubMed, Web of Science, The Cochrane Library, and EMbase databases to collect randomized controlled trials (RCTs) on the effects of exercise on blood lipid levels among patients with hypertension from inception to September 16th, 2021. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of the included studies. Stata 15.1 software and RevMan 5.0 software were then used to perform network meta-analysis. ResultsA total of 29 RCTs involving 2 519 patients were included. Compared with the control group, aerobic training (MD=−0.47, 95%CI −0.62 to −0.319, P<0.001), resistance training (MD=−0.37, 95%CI −0.63 to −0.11, P<0.05), and aerobic training combined with resistance training (MD=−0.61, 95%CI 0.88 to −0.34, P=0.005) reduced total cholesterol levels; aerobic training (MD=0.14, 95%CI 0.08 to 0.20, P<0.001), resistance training (MD=0.10, 95%CI 0.02 to 0.19, P<0.05), and aerobic training combined with resistance training (MD=0.12, 95%CI 0.02 to 0.23, P=0.038) increased high-density lipoproteins; aerobic training (MD=−0.32, 95%CI −0.48 to −0.15, P=0.001), resistance training (MD=−0.19, 95%CI −0.48 to −0.01, P<0.05), and aerobic training combined with resistance training (MD=−0.40, 95%CI −0.70 to −0.11, P<0.05) reduced low-density lipoproteins. The SUCRA probability sorting results showed that aerobic training had the most significant effect on the improvement of systolic blood pressure and diastolic blood pressure; aerobic exercise combined with resistance training had the largest effect on total cholesterol, triglycerides, low-density lipoproteins, and high-density lipoproteins. ConclusionsAerobic training combined with resistance training is the most effective exercise method to improve blood lipid levels for patients with hypertension. Due to the limited quantity and quality of the included studies, the above conclusions are needed to be verified by more high-quality studies.
Objective To investigate the feasibil ity of replacing urinary epithel ial cells with oral mucosa cell to reconstruct tissue engineered urethra by being seeded on bladder acellular matrix graft (BAMG). Methods Eighteen male New Zealand rabbits, aged 10 weeks, weighing 0.3-0.5 kg, were used in this study. Oral mucosa cell of 12 rabbits were isolated and seeded onto a culture dish with a feeder layer of 3T3 and a culture dish without 3T3, respectively. The morphologic change and growth condition of oral mucosa cells were observed by inverted phase contrast microscope after 2 days of seeding. The quantity of oral mucosa cells was counted using cell counting meter; the cell growth curve was drawn and the immunofluorescence staining with broad-spectrum keratin antibody was carried out. The bladders taken from the rest 6 rabbits were decelluled to make BAMG and the tissue of 1 cm × 1 cm was randomly selected to observe the effect of acellularization. The second passage oral mucosa cells cultured with 3T3 were appl ied to steril ized BAMG to obtain a issueengineered mucosa. The tissue-engineered mucosa was assessed using HE staining and scanning electron microscope after being cultured for 1 week. Results Oral mucosa cells seeded onto a feeder layer of 3T3 could be passaged for 7 or 8 generations with homogeneous forms and full function. Oral mucosa cells cultured without 3T3 could only be subcultured for 2 generations before aging and had multiple shapes and different sizes. Oral mucosa cells cultured by the two methods both started logarithmic growth on the 8th day and reached the peak value on the 14th day, which was indicated by the cell growth curve. However, more cells could be obtained through oral mucosa cells cultured with 3T3 than those cultured without 3T3. Oral mucosa cells manifestated green colour fluorescence cultured with or without 3T3. After the cells were removed, the BAMG presented as a porous membrane. The HE staining showed that the effect of acellularization was good and there were no cells at BAMG. The second passage oral mucosa cells cultured with 3T3 were expanded and seeded onto steril ized BAMG to obtain a tissue-engineered mucosa. Good compatibil ity of the compound graft was assessed using HE staining and scanning electron microscope. HE staining and scanning electron microscope showed that oral mucosa cells had good biocompatibil ity with BAMG after the tissue engineered mucosa was cultured for 1 week. Conclusion Oral mucosa cells of rabbit can be cultured in vitro and attain magnitude quantities. Oral mucosa cell also have good biocompatibil ity with BAMG and the compound graft could be a new material for urethral reconstruction.
ObjectiveTo investigate the effectiveness of digital three-dimensional (3D) printing osteotomy guide plate assisted total knee arthroplasty (TKA) in treatment of knee osteoarthritis (KOA) patients with femoral internal implants. Methods The clinical data of 55 KOA patients who met the selection criteria between July 2021 and October 2023 were retrospectively analyzed. Among them, 26 cases combined with femoral implants were treated with digital 3D printing osteotomy guide plate assisted TKA (guide plate group), and 29 cases were treated with conventional TKA (control group). There was no significant difference in gender, age, body mass index, side, Kellgren-Lawrence classification, preoperative visual analogue scale (VAS) score, Hospital for Special Surgery (HSS) knee score, knee range of motion, and other baseline data between the two groups (P>0.05). The operation time, intraoperative blood loss, incision length, postoperative first ambulation time, surgical complications; VAS score, knee HSS score, knee range of motion before operation, at 1 week and 3 months after operation, and at last follow-up; distal femoral lateral angle, proximal tibial medial angle, hip-knee-ankle angle and other imaging indicators at last follow-up were recorded and compared between the two groups. ResultsThe operation time, incision length, intraoperative blood loss, and postoperative first ambulation time in the guide plate group were significantly lower than those in the control group (P<0.05). In the control group, there were 1 case of incision rupture and bleeding and 1 case of lower limb intermuscular venous thrombosis, which was cured after symptomatic treatment. There was no complication such as neurovascular injury, incision infection, or knee prosthesis loosening in both groups. Patients in both groups were followed up 12-26 months, with an average of 16.25 months. The VAS score, HSS score, and knee range of motion improved at each time point after operation in both groups, and further improved with time after operation, the differences were significant (P<0.05). The above indicators in the guide plate group were significantly better than those in the control group at 1 week and 3 months after operation (P<0.05), and there was no significant difference between the two groups at last follow-up (P>0.05). At last follow-up, the distal femoral lateral angle, the proximal tibial medial angle, and the hip-knee-ankle angle in the guide plate group were significantly better than those in the control group (P<0.05). Conclusion The application of digital 3D printing osteotomy guide plate assisted TKA in the treatment of KOA patients with femoral implants can simplify the surgical procedures, overcome limitations of conventional osteotomy guides, reduce surgical trauma, achieve individualized and precise osteotomy, and effectively restore lower limb alignment and knee joint function.
ObjectiveTo investigate the clinical application of three-dimensional (3D) printing technique combined with a new type of thoracic pedicle screw track detector in thoracic pedicle screw placement.MethodsAccording to the characteristics of thoracic pedicle and common clinical screw placement methods, a new type of thoracic pedicle screw track detector was independently developed and designed. The clinical data of 30 patients with thoracic vertebrae related diseases who underwent posterior thoracic pedicle screw fixation between March 2017 and January 2020 were retrospectively analysed. Among them, there were 18 males and 12 females with an average age of 56.3 years (range, 32-76 years). There was 1 case of thoracic disc herniation, 4 cases of thoracic canal stenosis, 2 cases of ossification of posterior longitudinal ligament of thoracic vertebra, 16 cases of thoracic trauma, 2 cases of thoracic infection, and 5 cases of thoracic canal occupation. Three-dimensional CT of the thoracic vertebra was routinely performed preoperatively, and the model of the patient’s thoracic vertebra was reconstructed and printed out. With the assistance of the model, preoperative simulation was performed with the combination of the new type thoracic pedicle screw track detector, and detected no nails after critical cortical damage. During operation, one side was randomly selected to use traditional hand screws placement (control group), and the other side was selected to use 3D printing technique combined with new type thoracic pedicle screw track detector to assist thoracic pedicle screws placement (observation group). The single screw placement time, adjustment times of single screw, and blood loss during screw placement were compared between the two groups. The accuracy of screw placement in the two groups was evaluated according to postoperative CT imaging data.ResultsThe single screw placement time, adjustment times of single screw, and blood loss during screw placement in the observation group were significantly less than those in the control group (P<0.05). Postoperative CT examination showed that the observation group had 87 screws of grade 1, 3 screws of grade 2, and the acceptable screw placement rate was 100% (90/90); the control group had 76 screws of grade 1, 2 screws of grade 2, 11 screws of grade 3, and 1 screw of grade 4, and the acceptable screw placement rate was 86.7% (78/90); showing significant difference in screw placement between the two groups (χ2=12.875, P=0.001). All patients were followed up 6-18 months, with an average of 11.3 months. There was no complication of vascular, nerve, spinal cord, or visceral injury, and screws or rods broken, and no patient was revised.ConclusionThe 3D printing technique combined with the new type of thoracic pedicle screw track detector assisted thoracic pedicle screw placement is convenient, and significantly improves the accuracy and safety of intraoperative screw placement, and overall success rate of the surgery.
Objective To assess the cl inical significance of transpedicular screw insertion in lower cervical vertebra assisted by multi-spiral CT (MSCT) three dimentional (3D) image reconstruction techniques. Methods Eight cervical vertebra specimens were examined by MSCT, and the messages were sent to SGI02 Workstation; according to the parameter requirements of lower cervical pedicle fixation, by using post-process of volume rendering (VR) the condition was judged and multi-plannar reformation (MPR) was used to do individual analysis; and the ideal path of screw insertion was obtained andthe related parameters were measured. After preoperative plan being finished, referring to these measured parameters, 3.5 mm screws were inserted into C3-7 pedicles of these 8 specimens. After insertion of screws, MSCT scanning and 3D reconstruction were performed again to evaluate the accuracy of lower cervical pedicle screw inserting. From May 2007 to November 2009, 28 patients who received screw insertion in lower cervical spines were given MSCT scanning and 3D reconstruction to evaluate the illness situation, to confirm shortest fixation volumes, and to collect the parameters of aim pedicle screw insertion. Results The time of insertion for each screw was (392 ± 62) seconds. It was found that one pedicle was clausura (1.25%, 1/80) and five pedicle diameters in coronal view were less than 3 mm (6.25%, 5/80), which all were not fit for screw insertion. A total of 74 screws were placed successfully. One-time success rate of screw insertion was 95.95% (71/74). The total accuracy rate was 91.89% (68/74). Six screws penetrated (8.11%). According to the Richter penetrating classification: grade one was 6.76% (5/74) and grade two was 1.35% (1/74). There were significant differences (P lt; 0.05) in penetrated rate between our study and anatomic landmark local ization (47.37%), Miller methods (25.00%), and there was no significant difference (P gt; 0.05) when compared with Abumi method (6.70%), hopper method (7.10%), pipel ine deoppilation method (5.20%) and navigation technique (11.30%). In cl inical 28 cases, 121 screws were inserted; one pedicle was clausura and one was fissure fracture, which all were unfit for insert screw in preoperative plan, the surgery project was adjusted. After operation, 17 patients (76 screws) were given MSCT scanning again. A total of 67 screws (88.16%) were placed successfully. Nine screws (11.84%) penetrated, grade one was 7.89% (6/76) and grade two was 3.95% (3/76). Conclusion It is accurate to apply MSCT 3D reconstruction techniques to measure the ideal screw canal in preoperative individual ized plan. Strictly following individual quantitative data, the safety and accuracy of the surgery can be improved. And it is feasible and available to use MSCT MPR imaging to evaluate the accuracy of pedicle screw insertion.
