BACKGROUND:Tougu Xiaotong Capsule has pretty good clinical therapeutic effect on osteoarthritis of early and middle periods. However, the mechanism of Tougu Xiaotong Capsule is not ful y clarified. The RhoA GTPases can regulate chondrocyte apoptosis and hypertrophy.
OBJECTIVE:To observe the Tougu Xiaotong Capsule on the expression of Rac1and Cdc42 in tumor necrosis factor-α-induced in vitro cultured rat articular chondrocytes, and to explore its mechanism of action for combating osteoarthritis.
METHODS:Knee cartilage of the 4-week-old Sprague-Dawley rats was used to stably establish in vitro culture system of chondrocytes. Passage 3 chondrocytes were identified by toluidine blue staining. Chondrocyte apoptosis was successful y induced by 20μg/L tumor necrosis factor-αand then Tougu Xiaotong Capsule at different dosage (500, 100, 20 mg/L) was given after 24-hour incubation. MTT assay was used to detect cellsurvival, flow cytrometry to measure mitochondrial membrane potential, and western blot assay to determine the protein expression of Rac1, Cdc42, Bax and Bcl-2.
RESULTS AND CONCLUSION:Tougu Xiaotong Capsule could reduce tumor necrosis factor-α-induced apoptosis of chondrocytes to improve the survival rate of the cells, and at the same time, could down-regulate the protein expression of Rac1, Cdc42 and Bax and increase the protein expression of Bcl-2 significantly (P<0.05). Tougu Xiaotong Capsule possibly plays a therapeutic efficacy on osteoarthritis by reducing promote apoptosis Rac1, Cdc42 and Bax expression and increasing apoptosis inhibiting gene Bcl-2 expression, thereby to inhibit apoptosis of chondrocytes.

OBJECTIVE To explore the protective effect of polysaccharides from Salvia Chinensis Benth. (PSSC) on lipopolysaccharide (LPS) and D- galactosamine (GalN)- provoked mouse acute liver failure (ALF) and the possible molecular mechanism. METHODS Kunming mice were randomly divided into four groups: normal control, model, model+PSSC 30 and 100 mg·kg- 1 groups. PSCC was given once a day and for a week. To establish an ALF model, mice of model and PSSC groups were ip injected with LPS 10 μg·kg-1 and GalN 700 mg·kg-1 at the end of PSSC treatment. The microscopic structure of the liver was detected by HE staining. Serum and hepatic biochemical parameters of glutamic-oxalacetic transaminase (GOT), glutamic- pyruvic transaminase (GPT), catalase (CAT), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), malondialdehyde (MDA), and glutathione (GSH) were detected by colorimetric methods. The relative content of hepatic reactive oxygen species (ROS) was measured by DCFH-DA fluorescent probes. Levels of cytokines tumor necrosis factor-α (TNF-α), interleukin 1β(IL-1β) and IL- 6 in the serum and liver were detected by ELISA. Activity of caspase 3 in liver homogenates was detected by aspase 3 activity assay kit. RESULTS Compared with normal control group, in the liver of model group, hepatocytes were arrayed in disorder, cytoplasm of hepatocytes shrank, and boundaries between cells were fuzzy, the infiltration of a large number of inflammatory cells and tissue hemorrhage could be detected, pathological scores were elevated significantly (P<0.01), levels of MDA and ROS in the liver of ALF model mice were elevated to 2.2 and 4.3 times that of the normal control, respectively (P<0.01), the level of GSH decreased to 51% (P<0.01), and the activities of SOD, CAT and GSH- Px declined to 74%, 36% and 42%, respectively (P<0.01). Levels of TNF- α, IL- 1β and IL- 6 in the serum and liver of model group were increased (P<0.01), and caspase 3 activity was increased to 5.3 times that of the normal control (P<0.01). Compared with the model group, the number of surviving mice in PSSC groups increased, liver pathological scores declined (P<0.01), levels of MDA and ROS increased (P<0.01), levels of GSH, TNF-α, IL-1β and IL-6 in the liver and serum declined (P<0.01), and caspase 3 activity decreased (P<0.01). CONCLUSION PSSC is able to alleviate LPS and GalN-induced ALF in mice. Inhibition of hepatic oxidative stress, inflammatory response, and cell apoptosis is possibly implicated in the protective effect of PSSC.

Objective To investigate the myocardial protective effects of“integrated strategy”with HOE-642 plus modified K/Mg on canine heart grafts.Methods Sixteen donors-recipient pairs of adult canines were divided into the“integrated strategy”group,i.e.,donor hearts were protected with HOE-642 plus K/Mg(IS,n=8)and the routine method(RM,n=8)group.Both groups un- derwent hypothermia stored for 4 h,followed by orthotopic transplantation.Cardiac heamodynamics was measured and myocardial ultrastructure and myocardial water content were evaluated.Results One of 8 animal died of aortic anastomoses leakage in each group,and the rest could wean from car- diopulmonary bypass successfully.Preservation of left ventricular contractility,as well as left ventric- ular compliance was significantly better in the IS group than in the RM group(P＜0.05),also,per- centage of myocardial water content was significantly lower in the IS group than in the RM group(P＜0.05).Myocardial ultrastructures were not damaged significantly in both groups,however,better myocardial preservation were seen in the IS group.Conclusion Both the clinically used“routine meth- od”and“integrated strategy”might provide safe donor heart preservation for 4 h,but the later scheme conferred more optimal effects with alleviating the myocardial swelling,preserving myocardial ultra- structure integrity and enhancing postischemic-reperfusion cardiac functional recovery.

Objective:The aim of our study was to compare the short-term and long-term outcomes between minimally invaisive Ivor-Lewis esophagectomy(MIILE)and minimally invasive McKeown esophagectomy(MIME) for squamous cell carcinoma of middle and lower esophagus.Methods:The data of 268 patients diagnosed with middle and lower esophageal spuamous cell carcinoma who had received MIILE or MIME between August 2010 and March 2014 at department of thoracic surgery, The First Affiliated Hospital of University of Science and Technology of China(Anhui Provincial Hospital), was analyzed retrospectively. We divided the subjects into two groups according to the mode of the operation, each group was identified 81 patients after propensity score matching. We were using t test, χ2 test, Kaplan- Meier curve and Log- rank test to compare preoperative data and overall survival of the two groups. Results:Compared with MIME, MIILE had lower complication in pulmonary infection and anastomotic fistula, also had less operating time, whereas MIME had an advantage in the number of lymph nodes dissection adjacent to recurrent laryngeal nerve( P<0.05). The 1-year、3-year、5-year survival rate of MIILE were 87.7%、59.2%、45.9%, and the 1-year、3-year、5-year survival rate of MIME were 86.4%、58.7%、42.8%.There were no significant difference between two groups in 5-year survival rate. Conclusion:For squamous cell carcinoma of middle and lower esophagus, minimally invasive Ivor-Lewis esophagectomy and minimally invasive McKeown have no significant difference in long-term survival, but minimally invasive Ivor-Lewis esophagectomy has advantages in reduce the operating time, decrease pulmonary infection and anastomotic fistula during perioperative period.Nevertheless minimally invasive McKeown has an advantage in dissection of the lymph nodes adjacent to recurrent laryngeal nerve.

Objective: To analyze the learning curve of uniportal video-assisted thoracoscopic surgery (VATS) lobectomy for the treatment of resectable lung cancer. Methods: The clinical data of 160 patients with resectable lung cancer who underwent uniportal VATS lobectomy by a single surgical team between May 2016 and April 2017 at Department of Thoracic Surgery, the First Affiliated Hospital of the University of Science and Technology of China were analyzed retrospectively. The study group consisted of 90 male and 70 female patients with age of 28 to 84 years (median: 62 years). The patients were divided into four groups from group A to D according to chronological order. The operation time, incision length, intraoperative blood loss, number of dissected lymph nodes and nodal stations, the proportion of changes in operation mode, postoperative complications, chest drainage duration and hospitalization time were individually compared among the four groups by variance analysis and χ² test. Results: The 4 groups were similar in terms of incision length, chest drainage duration, number of dissected lymph nodes and nodal stations and postoperative hospitalization time (P>0.05). The difference of the operation time ((185.9±17.9) minutes vs. (139.9±10.7) minutes vs.(128.7±7.8) minutes vs.(124.0±9.3) minutes, F=219.605, P=0.000), intraoperative blood loss ((233.9±135.8) ml vs. (126.8±18.1) ml vs. (116.4±22.6) ml vs.(112.8±25.3) ml, F=26.942, P=0.000), the proportion of changes in operation mode (17.5% vs.7.5% vs. 5.0% vs. 5.0%, χ²=8.300, P=0.040), and the incidence of postoperative complications (27.5% vs. 10.0% vs. 10.0% vs. 7.5%, χ²=8.643, P=0.034) among the 4 groups was statistically significant. Conclusions Uniportal VATS lobectomy can be safely and feasibly performed for resectable lung cancer, learning curve for uniportal VATS lobectomy is approximately 40 cases. Operation time, intraoperative blood loss, postoperative complications and the proportion of changes in operation mode can be used as the main measures during surgery.

Objective: To evaluate the effect of the postoperative short-term quality of life between uniportal and three portal video-assisted thoracic surgery for radical lung cancer resection. Methods: The perioperative data and short-term quality of life of 120 patients received uniportal and three portal video-assisted thoracic surgery for radical lung cancer resection were analyzed from September to November 2017 at Department of Thoracic Surgery, the First Affiliated Hospital of University of Science and Technology of China. There were 64 male and 56 female patients aging of (62±10) years (ranging from 28 to 82 years). There were 60 cases received uniportal (uniportal group) and 60 cases received three portal video-assisted thoracic surgery (three-portal group). Quality of life by measurement of functional and symptom scales was assessed before surgery at baseline, and 1, 2, 4, and 8 weeks after the operation. The t test, χ² test, Fisher exact test and Wilcoxon rank-sum test were used to compare the date between the 2 groups. Repeated measurement variance was used for comparison of the quality of life at different time points. Results: There were no statistically significant differences in the clinicopathological features of the two groups (P>0.05). Intraoperative bleeding volume ((92±85) ml vs. (131±91) ml, t=2.387, P=0.019), postoperative catheter time ((4.4±3.1) days vs. (6.0±3.9) days, t=2.401, P=0.018), and postoperative hospitalization time ((6.2±4.0) days vs. (8.3±4.6) days, t=2.626, P=0.010) in the patients with uniportal group were less than that in three-portal group. Preoperative functional areas, symptom areas and overall health scores were similar in the two group. The functional areas such as physical function, role function, emotional function and social function and overall health status of uniportal group were significantly higher than those of three-portal group in postoperative time, while the fatigue and pain of uniportal group were significantly lower than that of three-portal group. Conclusions Uniportal video-assisted thoracic surgery can achieve the same safety and radical of three-portal video-assisted thoracic surgery. It has advantages in intraoperative bleeding volume, postoperative time after operation, hospitalization time and postoperative life quality.
