The mean of patients of consciousness recovery time, tracheal extubation time and stay in ICU time were 178±42 min,105±40 hours and 18±63 hours. The patients were discharged in 80±12 days. Racheal intubation were remained 12 hours in 180 patients after operation, 180 patients had good recovery without any anesthesia complications. Conclusion : Rational use of anesthetics and inotropics to stabilize hemodynamics during operation plays a key role in successful OPCAB.
Objective To explore key genes and mechanisms of depression aggravating Crohn disease. Methods In March 2023, the Public Health Genomics and Precision Health Knowledge Base and Gene Expression Omnibus database were used to identify the overlapping differentially expressed genes between Crohn disease and depression and the key genes were screened by Metascape, STRING, Cytoscape, and protein interaction network analysis. The Gene Expression Omnibus database was used to analyze the correlations between key genes and clinical pathologies such as Crohn Disease Endoscopic Index of Severity and intestinal microvilli length. Results There were 137 overlapping differentially expressed genes between Crohn disease and depression, and 25 key genes were further screened out. Among them, CREB1, FKBP5, MAPT, NTSR1, OXTR, PROK2, POMC, HTR2B, and PPARGC1A genes were significantly correlated with multiple clinical parameters. The functions of PROK2 and PROK2-related genes were mainly enriched in neutrophil and granulocyte migration, neutrophil and granulocyte chemotaxis, etc. Conclusions There are 25 key genes, especially CREB1, FKBP5, MAPT, NTSR1, OXTR, PROK2, POMC, HTR2B, and PPARGC1A, that possibly contribute to the establishment and deterioration of Crohn disease caused by depressive disorder. Among these genes, PROK2 showes the possibility of regulating immune cell (neutrophils and CD8+ T cells) infiltration.
Objective To summarize the diagnosis and treatment of fibular fracture in ankle fracture. MethodsRelevant literature at home and abroad in recent years was widely consulted, and various types of fractures were discussed and summarized according to Danis-Weber classification. ResultsConservative treatment is not an ideal treatment for type A avulsion fracture. The operation method should be determined according to the position and size of bone mass. For simple type B fracture, both conservative treatment and surgical treatment can achieve good results. When the position of type C fracture is high and does not affect the stability of ankle joint, it can be treated conservatively, while when the position is low and affects the stability of ankle joint, it needs surgical treatment. ConclusionFirst of all, whether the fibular fracture in the ankle fracture is stable or not should be determined. Whether it is treated surgically or not, the purpose is to restore the tibiofibular syndesmosis and restore the motor function of the ankle.
Objective To observe the effectiveness of prevention and management of venous thromboembolism (VTE) in the day surgery wards, analyze the influencing factors of VTE occurrence in postoperative patients, in order to reduce the occurrence of VTE adverse events, improve the utilization of medical resources, and enhance the quality of day care. Methods The patient data of the Daytime Diagnosis and Treatment Center of Deyang People’s Hospital between January 2020 and December 2023 were retrospectively selected. According to the implementation time of VTE prevention and control in the day surgery wards, patients between 2022 and 2023 were selected as the observation group, and patients between 2020 and 2021 were selected as the control group. The incidence and the influencing factors of postoperative of VTE were compared between the two groups. Results A total of 2 300 patients were included, with 1 150 cases in each group. The comparison of in-hospital [12 cases (1.0%) vs. 3 cases (0.3%)] and post discharge [7 cases (0.6%) vs. 1 case (0.1%)] VTE incidence rates between the control group and the observation group showed statistically significant differences (P＜0.05). Among the 9 specialties in the Daytime Diagnosis and Treatment Center, the incidence of VTE in thoracic surgery (1.58%), vascular surgery (1.51%), and hepatobiliary surgery (1.29%) ranked among the top 3. The results of multiple logistic regression analysis showed that fourth grade surgery, lower limb surgery, and large intraoperative bleeding (>100 mL) were the influencing factors for postoperative VTE (P<0.05). Conclusions There are many reasons for VTE occurrence, and it is necessary to prevent and treat VTE in the day surgery ward. More attention should be paid to the patient’s surgical grading, intraoperative bleeding volume, and surgical site.
Abstract： Objective To analyze the mid-term outcomes after correction of type Ⅰ and type Ⅱ persistent truncus arteriosus in all patients operated in our institution over the past 5 years. Methods Between May 2006 and October 2010, 17 patients, mean age 4.7（ 0.7-19.0）years, underwent repair of truncus arteriosus（ type Ⅰ in 13 and type Ⅱ in 4） in Fu Wai Cardiovascular Hospital. Some other concomitant cardiovascular malformations included truncal valve regurgitation, partial anomalous pulmonary venous connection, mitral regurgitation and atrial septal defect. Their average pulmonary vascular resistance was （4.4±2.2） Wood units detected by cardiac catheterization before operation. Repair with reconstruction of the right ventricular to pulmonary artery continuity was performed using a valved conduit in all 17 patients （aortic homografts in 3, pulmonary homografts in 2, and bovine jugular vein in 12 patients）. Survivors were followed up for assessment of residual heart lesions. Results The early mortality was 5.8% （1/17）. The mean cardiopulmonary bypass time was （165±52） min, mean aortic cross-clamping time was （114±29） min, and mean postoperative ventilation time was （106±148） h. Two patients had pleural effusion after surgery, 2 patients underwent tracheostomy, and other patients recovered uneventfully. The surviving 16 patients were followed up for 0.6-5.0 years. All patients were alive with their original conduit during follow-up. No patient required re-operation for conduit dysfunction after correction. Conclusion Truncus arteriosus remains a challenging congenital heart disease. For patients with type Ⅰ and type Ⅱ persistent truncus arteriosus who have missed their best age for correction, cardiac catheterization should be routinely examined, and the operation should be performed if the pulmonary vascular resistance is under 8 Wood units before operation. Although the short- and mid-term results of surgery are good, more observations are needed to assess its long-term effect.
ObjectiveTo explore the effectiveness of traditional Chinese medicine (TCM) acupuncture analgesia after laparoscopic total extraperitoneal inguinal hernia repair (TEP), aiming to reduce the use of analgesics post-surgery. MethodsPatients who underwent unilateral TEP in the Department of Hernia and Abdominal Wall Surgery at our hospital from May 2022 to May 2023 were selected as research subjects. Those who met the inclusion and exclusion criterias were randomly assigned to three groups: TCM acupuncture analgesia group, traditional Chinese medicine acupuncture analgesia plus western medicine analgesia group (referred to as Chinese and western medicine analgesia group), and western medicine analgesia group. The basic information, postoperative numerical rating scale (NRS) pain scores, postoperative recovery indicators, and complication rates of the three groups were analyzed and compared.ResultsThere was no statistically significant differences in the basic data of patients across the three groups (P>0.05). There were significant differences in NRS score, recovery time of intestinal function, first urination time after operation and first ambulation time after operation at each time point after analgesia (6 h, the next morning, 48 h, 72 h and 96 h after operation) among the three groups (P<0.05). The NRS scores in both the TCM acupuncture analgesia group and the Chinese and western medicine analgesia group were lower than those in the western medicine analgesia group (P<0.05), Additionally, postoperative recovery outcomes were better in the TCM acupuncture analgesia group and the Chinese and western medicine analgesia group compared with the western medicine group (P<0.05). There was no significant difference of the above results compared between the TCM acupuncture analgesia group and the Chinese and western medicine analgesia group (P>0.05). There was no significant difference in postoperative complications among the three groups (P>0.05). ConclusionTCM acupuncture analgesia following TEP surgery is effective and leads to improved postoperative recovery compared with the use of oral analgesics alone, without an increase in adverse reactions.
Objective To investigate the evaluation value of serum interleukin-34 (IL-34), macrophage migration inhibitor (MIF), osteopontin (OPN) and hypersensitive C-reactive protein (hs-CRP) in the diagnosis and prognosis of active pulmonary tuberculosis. Methods Clinical data of 100 patients with active pulmonary tuberculosis admitted from June 2019 to June 2022 were selected as an observation group and retrospectively analyzed. All patients received standardized anti-tuberculosis therapy for 6 months and were divided into a good prognosis group (76 cases) and a poor prognosis group (24 cases) according to the prognosis. Another 80 healthy volunteers who underwent physical examination during the same period were selected as the control group. Serum levels of IL-34, MIF, OPN and hs-CRP were detected in each group, and the value of serum IL-34, MIF, OPN and hs-CRP in the diagnosis and prognosis of active pulmonary tuberculosis was analyzed by receiver operating characteristic curve (ROC curve). Results Serum levels of IL-34, MIF, OPN and hs-CRP in the observation group were higher than those in the control group (all P<0.05). ROC curve showed that serum IL-34, MIF, OPN, hs-CRP had a certain diagnostic value in active pulmonary tuberculosis, with area under ROC curve (AUC) of 0.864, 0.870, 0.865, and 0.880, respectively (all P<0.01), and the combination of the four indexes had a higher diagnostic value (AUC=0.902, P<0.01). Serum levels of IL-34, MIF, OPN and hs-CRP in the good prognosis group were lower than those in the poor prognosis group (all P<0.05). ROC curve showed that serum IL-34, MIF, OPN, hs-CRP had a certain value in evaluating the prognosis of active pulmonary tuberculosis, with AUC of 0.850, 0.874, 0.837, and 0.842, respectively (all P<0.01), and the combined value of the four indexes was higher (AUC=0.923, P<0.01). Conclusion The combined detection of serum IL-34, MIF, OPN and hs-CRP has high value in the diagnosis and prognosis assessment of active pulmonary tuberculosis.
Objectives We aimed to assess the methodological qual ity of RCT on acupuncture for migraine prophylaxis. Methods With the searching terms including acupuncture, migraine, prophylaxis and prevent, etc, the database of the Cochrane Library (Issue 4, 2007), MEDLINE (1966-2007), EMBase (1966-2007), CBM (1978-2007) and CMCC (1994-2007) were searched from their date of start publ ication. Chinese medical journals and relevant academic conference proceedings were hand searched as well. Several items in included trials were assessed, including methodology, diagnostic criteria, inclusion/exclusion criteria, acupuncture/control interventions, outcome measures and follow-up, etc. Result Among the 12 included trials, 9 trials overseas were high-qual ity and 3 in China were low-quality. Frequency or days of migraine attacks and SF-36/SF-12 were often evaluated as outcome measures in western countries, while headache index was used in China. Among the 12 trials, 9 reported the follow-up outcomes and 8 mentioned adverse events. Conclusion There was no high qual ity trial on acupuncture for migraine prophylaxis in China. The outcome measures in trials published in China by now can not evaluate the outcomes of acupuncture for migraine prophylaxis accurately. To study designs, advantages of trials oversea can be used for reference. To Chinese cl inical physicians, prophylactic therapy and abortive therapy of migraine should be distinguished in order to design high-qual ity study on acupuncture for migraine prophylaxis.
