目的 评价盐酸氨基葡萄糖治疗膝骨关节炎的疗效。 方法 将2012年1月－5月收治的150例膝骨关节炎患者随机分为A、B、C组。A组给予盐酸氨基葡萄糖治疗，B组给予碳酸钙D3片治疗，C组给予盐酸氨基葡萄糖联合碳酸钙D3片治疗，疗程8周。3组患者膝关节疼痛发作时服用塞来昔布并记录用量。比较试验前后3组患者骨关节炎指数评分（WOMAC）以及第1、8周塞来昔布用量变化情况。 结果 3组患者WOMAC总分、疼痛程度评分、关节僵硬程度评分、日常活动困难程度评分改善值比较，差异均无统计学意义。经过8周治疗，塞来昔布每周用量减少值A、B、C组分别为（0.41 ± 0.17）、（0.16 ± 0.22）、（0.46 ± 0.19）g，A、C组高于B组（P＜0.01），A、C组每周用量减少值差异无统计学意义（P＞0.05）。 结论 短期使用盐酸氨基葡萄糖治疗膝骨关节炎，在关节疼痛、僵硬及功能改善方面并不优于碳酸钙D3片，但可通过减少非甾体抗炎药物用量，使患者获益。
【Abstract】ObjectiveTo study the effects of endothelin (ET) and Xuesaitong injection on hepatic, renal and myocardial tissues after bile duct ligation (BDL) in rabbits. MethodsSeventytwo rabbits were randomly divided into three groups: BDL group (24 rabbits), BDL+Xuesaitong injection group (24 rabbits), and sham operation group (24 rabbits). Each group was subdivided into four subgroups of postoperative 3, 6, 9 and 12 d (6 rabbits in each subgroup). Automatic biochemical analysis equipment was used to detect the levels of serum TBIL, ALT, BUN and Crea. The levels of ET in plasma, hepatic, renal and myocardial tissues were measured with radioimmunological method. ResultsThe levels of ET in plasma, hepatic, renal and myocardial tissues in both BDL group and BDL+Xuesaitong injection group were higher than those of sham operation group (P＜0.01). The levels of ET in plasma and tissues of BDL+Xuesaitong group were lower than those in BDL group (P＜0.05). ConclusionObstructive jaundice can lead to an increase of ET in plasma, hepatic, renal and myocardial tissues, the level of ET increases with the time of obstruction. Xuesaitong injection may play a protective role in the injury of hepatic, renal and myocardial tissues after obstruction by decreasing the level of ET in plasma and tissues.
Surgery is the preferred treatment for early esophageal cancer. Minimally invasive esophagectomy (MIE) can significantly reduce the incidence of postoperative complications and mortality, but due to the complex esophageal anatomy, intraoperative esophageal exposure, separation, anastomosis and lymph node dissection are difficult. The da Vinci surgical system provides a 3D vision and a more flexible as well as stable robotic arm, which is very helpful in completing fine surgical procedures. Robot-assisted minimally invasive esophagectomy(RAMIE) has been carried out in a number of countries, including China. Robot-assisted Ivor-Lewis esophagectomy (RAILE) is a transthoracic approach of robots developed in recent years. This paper summarizes the current researches on RAILE.
ObjectiveTo enhance the management of occupational exposure, improve post-exposure reporting, promote post-exposure follow-up, reduce blood-borne infections caused by exposure, and ensure occupational safety among medical staff by using comprehensive measures based on nosocomial infection management system.MethodsAll the reported cases of occupational exposure were retrospectively collected from August 2012 to July 2018. The cases were divided into the control group (from August 2012 to July 2015) in which the data were reported in paper, and the observation group (from August 2015 to July 2018) in which the data were reported by nosocomial infection management system. The report and follow up results of occupational exposure in the two groups were compared and analyzed.ResultsAfter three years application of nosocomial infection management system, the occupational exposure report increased 95.8% (increased from 16.7 cases per year to 32.7 cases per year); the follow-up ratio of occupational exposure after one month,3 months and 6 months increased from 65.0% to 93.3% (χ2=15.184, P<0.001), 45.0% to 73.3% (χ2=9.033, P=0.003), and 25.0% to 53.3% (χ2=8.522, P=0.004), respectively.ConclusionApplication of nosocomial infection management system can increase the report of occupational exposure and the follow-up ratio of occupational exposure significantly.

Objective To evaluate the effect of ECRS management model on the quality of prevention and control of hospital infection with multidrug-resistant organisms (MDROs). Methods The data related to the prevention and control of MDROs in the First Hospital of Nanchang in 2020 and 2021 were retrospectively collected. The hospital implemented routine MDRO infection prevention and control management in accordance with the Expert Consensus on the Prevention and Control of Multi-drug Resistant Bacteria Nosocomial Infection in 2020. On this basis, the hospital applied the four principles of the ECRS method to cancel, combine, rearrange and simplify the MDRO infection prevention and control management. The detection rate of MDROs on object surfaces, the incidence rate of hospital infection of MDROs, the compliance rate of hand hygiene, the implementation rate of contact isolation prevention and control measures, and the pass rate of MDRO infection prevention and control education assessment were analyzed and compared between the two years. Results The detection rate of MDROs on the surfaces in 2021 was lower than that in 2020 (9.39% vs. 31.63%). The hospital-acquired MDRO infection rate in 2021 was lower than that in 2020 (1.18% vs. 1.46%). The hand hygiene compliance rates of medical staff, workers and caregivers in 2021 were higher than those in 2020 (90.99% vs. 78.63%, 73.51% vs. 45.96%, 70.96% vs. 33.71%). The implementation rate of contact isolation prevention and control measures in 2021 was higher than that in 2020 (93.31% vs. 70.79%). The qualified rates of MDRO infection prevention and control education in medical personnel, workers and caregivers in 2021 were higher than those in 2020 (96.57% vs. 81.31%, 76.47% vs. 47.95%, 73.17% vs. 34.19%). All the differences above were statistically significant (P<0.05). Conclusion ECRS management mode can improve the execution and prevention level of MDRO hospital infection prevention and control, and reduce the incidence of MDRO hospital infection.
Objective To investigate the factors influencing the occurrence of postoperative pulmonary complications (PPCs) in liver transplant recipients and to construct Nomogram model to identify high-risk patients. Methods The clinical data of 189 recipients who underwent liver transplantation at the General Hospital of Eastern Theater Command from November 1, 2019 to November 1, 2022 were retrospective collected, and divided into PPCs group (n=61) and non-PPCs group (n=128) based on the occurrence of PPCs. Univariate and multivariate logistic regression analyses were used to determine the risk factors for PPCs, and the predictive effect of the Nomogram model was evaluated by receiver operator characteristic curve (ROC) and calibration curve. Results Sixty-one of 189 liver transplant patients developed PPCs, with an incidence of 32.28%. Univariate analysis results showed that PPCs were significantly associated with age, smoking, Child-Pugh score, combined chronic obstructive pulmonary disease (COPD), combined diabetes mellitus, prognostic nutritional index (PNI), time to surgery, amount of bleeding during surgery, and whether or not to diuretic intraoperatively (P<0.05). Multivariate logistic regression analysis showed that age [OR=1.092, 95%CI (1.034, 1.153), P=0.002], Child-Pugh score [OR=1.575, 95%CI (1.215, 2.041), P=0.001], combined COPD [OR=4.578, 95%CI (1.832, 11.442), P=0.001], combined diabetes mellitus [OR=2.548, 95%CI (1.024, 6.342), P=0.044], preoperative platelet count (PLT) [OR=1.076, 95%CI (1.017, 1.138), P=0.011], and operative time [OR=1.061, 95%CI (1.012, 1.113), P=0.014] were independent risk factors for PPCs. The prediction model for PPCs which constructed by using the above six independent risk factors in Nomogram had an area under the ROC curve of 0.806. Hosmer and Lemeshow goodness of fit test (P=0.129), calibration curve, and decision curve analysis showed good agreement with Nomogram model. Conclusion The Nomogram model constructed based on age, Child-Pugh score, combined COPD, combined diabetes mellitus, preoperative PLT, and time of surgery can better identify patients at high risk of developing PPCs after liver transplantation.
Objective To summarize the experience of diagnosis and treatment of acute abdominal pain caused by hepatic hydatid. Methods The preoperative diagnosis, the surgical methods and the curative effect after operation of 297 patients with acute abdominal pain caused by hepatic hydatid who were treated in our hospital from 1960 to 2004 were analyzed. Results The healing rate was 95.96% (285/297 cases), and the death rate was 4.04% (12 /297 cases). Six out of 12 cases of death were caused by diffusive biliary peritonitis and allergic shock attributable to the rapture of hydatid into abdominal cavity. Two patients died of malnutrition caused by the spreading of Echinococcus and the correspondingly repeated operations. Another 4 patients with giant hydatid containing 7 000-12 000 ml fluid, died of hepatic insufficiency caused by the postoperative infection in the cyst. Conclusion The acute abdominal pain caused by hepatic hydatid should be treated mainly through emergency operation and the necessary antianaphylaxis, anti-infection and antishock therapies should also be used at the same time.
ObjectiveTo determine the expression change of activating transcription factor 5 (ATF5) in human rectal cancer tissue, and analyze the correlation between ATF5 expression and the clinicopathologic parameters of rectal cancer. MethodsNinetytwo paired samples of rectal cancer tissue and more than 5 cm distant normal rectal tissue were obtained from inpatients between March 2009 and October 2009 in this hospital. ATF5 mRNA and protein expressions were detected by quantitative real-time RT-PCR and immunohistochemical staining. ResultsThirty-three (35.9%) cases of rectal cancer showed ATF5 mRNA overexpression; however, the expression level of ATF5 mRNA in the rectal cancer tissue was not statistically different from that in the normal rectal tissue (P=0.363). There was no evidence for the relationship between the ATF5 mRNA expression and the patients’ age, gender, histological type, tumor differentiation degree, invasive depth, lymph node metastasis, distance metastasis, or TNM stage. In contrast, the positive expression rate of ATF5 protein in the rectal cancer tissue was significantly higher than that in the normal rectal tissue (P=0.000). Moreover, the ATF5 protein expression was correlated with the tumor differentiation degree (P=0.013), but not with other clinicopathologic features (Pgt;0.05). ConclusionsThe results suggest that ATF5 protein may be related to the carcinogenesis and differentiation of human rectal cancer. However, further researches are required to prove the correlation.
Objective To decrease the operative difficulty, with the purpose of looking for an orthotopic liver autotransplantation model which not only materializes the liver transplantation but also possesses higher survival rate. Methods This model was established via portal vein perfusion in thirty rats, and from which the result of the liver after perfusion, the operative time and the survival rate were observed. Liver tissues were researched at 24 h after operation under the light microscope. Results This model was easy to be perfused, the operative time was (48±3.0) min and the survival rate was 96.7% (29/30). The structure of hepatic tissue was basically normal with a little hydropic degeneration under the light microscope. Few erythrocytes residual occurred in the interlobular arteries under the light microscope. Conclusion The orthotopic liver autotransplantation model via portal vein perfusion has an exclusively blockage pattern which possesses a higher survival rate. It prevents the injury of immunological rejection and purely reflects the hepatic ischemia-reperfusion. But it is better to be applied in the non-hepatic artery anastomosis or the research nothing to do with the hepatic artery because the hepatic artery does not have sufficient perfusion.
