Objective To make a retrospective analysis on an early clinical outcome of total knee arthroplasty (TKA) for the knees with different degrees of flexion-contracture deformities. Methods Ninety-seven knees of 65 patients undergoing total knee arthroplasty with the Scorpio posterior-stabilized knee prosthesis from January 2000 to December 2003 were reviewed, including 51 osteoarthritis patients (74 knees) and 14 rheumatoid arthritis patients (23 knees). Thirtythree patients underwent unilateral TKA, and 32 patients underwent bilateral TKA. The average range of motion (ROM) before operation was 82.8°(range, 5-140°).According to the preoperative flexion-contracture degrees of the knees, these patients were divided into 2 groups, group A and group B. Group A consisted of the patients with flexioncontracture less than 20° (range, 0-15°), and group B consisted of the patients with flexion-contracture not less than 20° (range, 20-60°). In group A, the average flexion-contracture degree, ROM, KSS (knee society score), and function score were 10.7±8.0°, 104.6±20.0°, 29.1±18.0, and 32.6±20.7, respectively. But the corresponding data were much worse ingroup B than in group A, which were 28.2±7.8°, 60.8±26.6°, 12.1±13.2, and 26.8±18.1. All the operations were primary total knee arthroplasty, and they were performed by the same group of surgeons. The time for the prosthesis installed lasted for 25.6 minutes, and the average tourniquet time was 34.7 minutes. Three or four days after operation, the patients began the continuous passive motion (CPM) and active functional exercise of the knee.Results The patients were followed up for an average of 2 years and 7 months(range, 8 mon-3.5 yr). During the follow-up period, the average flexion-contracture degree, ROM, KSS, and function score in group A were 0.4±2.1°, 108.6±19.0°, 82.1±13.8, and 72.3±29.1, respectively; and the corresponding data in group B were 1.3±3.2°, 986±16.4°, 75.9±8.2, and 81.4±26.9, respectively. There was no significant difference between the 2 groups. No revision or deep infection was found. Conclusion The curative effect is mainly determined by the surgeon’s good operational skills, rich clinical experience, and familiarity with the prosthesis, and it is not influenced by severity of the knee flexioncontracture deformity. The knee ROM after TKA, which has a “toward middle ROM”phenomenon, is influenced by many clinical factors. It is very important for the patientto perform a functional exercise of the knee as early as possible after operation.
A comparative study was given to a group of grafted tendons on rabbits either with complete immobilization or early controlled passive mobilization of the affected parts immediately following operation. In the study, the healing mechanism, adhesion formation and breaking strength at the grafted site of the tendons were included. The results showed that early controlled passive mobilization had no influence on the survival and its healing process, but the adhesion surrounding tendons would be looser and the vessels on the surface, of the grafted tendons would be orientated longitudinally enhancing tendon gliding promoted collagen it would also promote collagen production and thus increased the rupturing strength at the grafted site.
ObjectiveThe purpose of the research is to study the distribution and early warning of electroencephalogram (EEG) in acute mountain sickness (AMS). MethodsA total of 280 healthy young men were recruited from September 2016 to October 2016. The basic data were collected by the centralized flow method, the general situation of the division of the investigators after the training, the Lewis Lake score, the computer self-rating anxiety scale and depression scale, and the collection of EEG. Follow up in three months. Results94 of the patients with AMS, morbidity is 33%, 21 (22.34%) of the patients are moderate to severe, 73 (77.66%) are mild, morbidity is 26.67%. The abnormal detection rate of electrogram was 7.9% (22/280), which were mild EEG, normal EEG abnormal rate was 8.6% (16/186), abnormal detection rate of mild AMS was 4.1% (3/73), and the abnormal detection rate was 14.3% (3/21) in the medium / heavy AMS. The latter was significantly different from the previous (P < 0.05). Three months follow-up of this group of patients with 0 case of high altitude disease. Conclusions The EEG in AMS is mainly a rhythm irregular, unstable, poor amplitude modulation; or two hemisphere volatility difference of more than 50% or slightly increased activity. The result is statistically significant, suggesting that EEG distributions has possible early warning of AMS.
Objective To study the relationship between early gastric cancer and MiB-1 expression. Methods Resected early gastric cancer from 99 cases were studied by immunohistochemical method. Results MiB-1 proliferation index (MiB-1 PI) was related to patient ’s age, tumor size, location and depth of invasion. MiB-1 PI was higher in differentiated adenocarcinomas than in undifferentiated adenocarcinomas(P＜0.01). Cancers with lymphatic vessel invasion or lymph node metastasis had higher MiB-1 PI (P＜0.05). The postoperative survival was related to MiB-1 proliferation grade (MiB-1 PG), being higher in MiB-1 PG 1,2 grade than that in MiB-1 PG 3,4 grade. Conclusion Even in the early stage of gastric cancer, tumor proliferation activity was related to patients’ prognosis.
Objective To investigate the development and significance of the expression of early growth response gene-1 （EGR-1） in autogenous vein graft in rats and detect the role of it in intimal hyperplasia. Methods Autogenous vein graft model was established in 90 Wistar rats, transplanting the right jugular vein to infra renal abdominal aorta by microsurgical technique. The vein graft samples were harvested at hour 1, 2, 6 and 24, day 3, 7,14, 28 and 42 after procedure. Normal vein as control group. Egr-1 mRNA was measured by reverse transcription-PCR and in situ hybridization. Western blot and immunohistochemistry were used to detect the protein expression of Egr-1. Results Intimal hyperplasia reached peak at day 28 after autogenous vein graft surgery. Egr-1 mRNA and Egr-1 protein hadn’t been found in the normal vein. The expressions of Egr-1 mRNA and Egr-1 protein had biphasic changes. By reverse transcription-PCR and in situ hybridization, we found that the level of Egr-1 mRNA rose at 1 hour after graft, the expression of Egr-1 mRNA was (35±7)%. Decline at hour 6， 24 and day 3, the positive rates of Egr-1 mRNA were (8±2)%, (8±6)% and (8±4)% respectively. Reincrease at day 7, a peak at day 28, the positive rate of Egr-1 mRNA was (45±6)% (compared with other phase, P＜0.01). At day 42, the expression of Egr-1 mRNA declined again. Immunohistochemical staining and Western blot revealed Egr-1 protein had expressed at hour 2 early phase, the expression of Egr-1 protein was (30±5)%, and until to hour 6. The level of Egr-1 protein was decrease at hour 24 and day 3, the positive rates were (7±3)% and (7±8)% respectively. A peak at day 28, the positive rate of Egr-1 protein was (40±9)% (compared with other phase, P＜0.01). We found that immu-noreative Egr-1 located vascular smooth muscle cells （VSMCs） and monocytes/macrophages in tunica media at the early phase of day 7 and 14, and in neointimal and medial VSMCs at later phase of day 28. Egr-1 was also present in the endoluminal endothelial cells. Conclusion In autogenous vein graft, Egr-1 plays an important role in the proliferation of VSMCs. Egr-1 may become a new target for the prevention and therapy of intimal hyperplasia, stenosis and emphraxis after vein graft.
ObjectiveTo systematically review the efficacy of early physical rehabilitation for patients with stroke-induced hemiplegia. MethodsDatabases including PubMed, Web of Knowledge, The Cochrane Library (Issue 7, 2014), EMbase, CNKI, VIP and WanFang Data were searched to collect randomized controlled trials (RCTs) about early physical rehabilitation for patients with stroke-induced hemiplegia from inception to 1st August 2014. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then, metaanalysis was performed using RevMan 5.2 software. ResultsA total of 6 RCTs were included. The results of metaanalysis showed that, after 1 month of treatment, the Fugl-Meyer scores (MD=18.02, 95%CI 6.24 to 29.80, P=0.003) and BI scores (MD=32.32, 95%CI 24.28 to 40.36, P<0.000 01) in the early physical rehabilitation group were higher than that in the conventional rehabilitation group. But after 3 months of treatment, there were no statistical differences between two groups in the proportion of patients with 0-2 MRS scores, mortality and the incidence of complications. ConclusionCurrent evidence shows that early physical rehabilitation can effectively improve the limb motor function and daily living ability in patients with stroke-induced hemiplegia. However, due to the limited quantity and quality of the include studies, more large-scale, high quality RCTs are needed to verify the above conclusion.
ObjectiveTo evaluate the effect of the early enteral nutrition（EEN） on the natural course in dogs with severe acute pancreatitis（SAP）.MethodsSAP model was induced by injecting 1 ml/kg of combined solution of 5% sodium taurocholate and 8 000-10 000 BAEE units trypsin/ml into pancrease via pancreatic duct.Fifteen dogs were divided into parenteral nutrition(PN) group and EEN group.Two groups were isonitrogenous and isocaloric.EEN was used at postoperative 24 h.Systemic plasma endotoxin level was quantified by the chromogenic limulus amebocyte lysate technique.Both portal and systemic blood sample were obtained before and 1，4，7 d following SAP, and cultured for aerobic as well as anaerobic bacterial.Serum glucose, calcium,amylase and lysosomal enzymes were determined.All dogs were injected with 1.85×106 Bq 125IBSA 4 h before sacrificed.The 125IBSA index of the pancreas/muscle and pancreas/blood was measured,and pancreas pathology was observed.Specimens of tissue from mesenteriolum and mesocolon lymph nodes,lung,pulmonary portal lymph nodes and pancreas were removed,weighed and homogenized in grinding tubes.Aliquots of the homogenata were cultured as blood mentioned above.The thickness of mucosa,the whole gut layer,the height of intestinal villi and their protein and DNA contents in the intestinal and transverse colon were determined.ResultsThe study showed that EEN significantly reduced the levels of systemic plasma endotoxin and the magnitude of bacterial translocation to the portal and systemic blood and distant organ,serum glucose in PN group was higher than that in EEN after SAP 4 d.There were no difference between two groups in the data of serum calcium,amylase and lysosomal enzymes,pathologic index and 125IBSA index of pancreas/muscle and pancreas/blood.EEN improved the gut barrier function by increasing the thickness of mucosa,the whole gut layer and the height of intestinal villi,increasing its protein and DNA contents in the bowel.ConclusionOur results suggest that EEN is safe and effective,and can decrease the rate of intestinal bacterial translocation.
ObjectiveTo investigate the clinical effects of early enteral nutrition in severe thoracic trauma patients requiring mechanical ventilation. MethodsWe randomly allocated 60 patients with thoracic trauma requiring mechanical ventilation into two groups by drawing lots including an early enteral nutrition (EEN) group and a parenteral nutrition (PN) group in our hospital between January 2013 and September 2014 year. There were 30 patients in each group. We compared the recovery results of the patients between the two groups. ResultsAfter the treatment of 7 and 14 days, indicators in the EEN group were better than before significantly and better than those in the PN group; diarrhea rate average days of ICU and the average days of hospital decreased significantly with statistical differences (P<0.05). There was no statistical difference in ventilator-associated pneumonia or the incidence of stress ulcer between the two groups (P>0.05). ConclusionEarly enteral nutrition in severe chest trauma patients requiring mechanical ventilation may promote protein synthesis, improve the nutritional status of patients, correct negative nitrogen balance, reduce inflammation response, reduce the complications.
ObjectiveThis study aimed to explore the timing of the long-term antiepileptic drugs (AEDs) therapy in patients with stroke related seizures. MethodsWe enrolled 90 Patients with post-stroke seizures who diagnosed in neurology and epilepsy specialist clinic of Tianjin Medical University General Hospital and followed up for at least 12 months from September 2014 to August 2016. The patients were divided into early-onset seizure group (occurring within 2 weeks of stroke) and late-onset seizure group (occurring after 2 weeks of stroke).The two groups were subdivided into treated and untreated group after the first seizure. ResultsThe patients were followed up for 12~96m (median 20m). 31 patients in ES group, 19 of which in treated group and 12 of which in untreated group. 59 patients in LS group, 36 of which in treated group and 23 of cases in untreated group. The recurrence rate of second seizures occurred in each group and the comparison between the subgroups in the 3rd, 6th, 9th and 12th mouth of follow-up as follows. 1 LS group compared with the group of ES, the recurrence rate of second seizures was high (25.81%~38.71% vs. 49.15%~69.49%), and there was statistical difference (P < 0.05). 2 The recurrence rate of ES in untreated group was lower than that in untreated LS group (16.77% 33.33% vs. 56.52% 73.91%), but only in 3m and 12m the difference was statistically significant (P < 0.05). 3 There was on statistically significant different in ES treated group compared to untreated group, LS treated group compared to untreated group, ES treated group compared to LS treated group (P > 0.05). Both in group of ES and LS, The ratio of seizure recurred patients at different time points during follow-up period was highest at the time of 3m, 3 6m followed, within six months respectively as high as 91.67% and 76.59%. ConclusionOnly one early-onset seizure after stroke can be suspended long-term AEDs treatment, once it recurred that indicates the need for treatment. However, the recurrence rate of late-onset seizure was higher than that of early-onset seizure and it should be given long term AEDs treatment after the first seizure.
