Fourteen days and twenty-eight days afterthe intervention,the knee-joint function scores ofthemoxibustion group and electroacupuncture group weresignificantlyhigherthan those oftheCelebrex group (P<0.05).ConclusionMoxibustion therapy can improve the clinical symptoms and the knee-joint function in patients with KOA,similar to the electroacupuncture group and Celebrex group, and the moxibustion group has better effect in improving theknee-joint functioncompared to the Celebrex group.

Mitochondrial dysfunction is closely related to the occurrence and development of benign and malignant diseases of the pancreas. Mitochondrial membrane of the respiratory chain electron transfer and energy transfer plays an important role in maintaining normal cellular function. When the respiratory chain was disrupted, the oxidative stress was increased in the cell, and produced a large number of oxide intermediate products which target mitochondrial protein, DNA, etc, lead to mitochondrial dysfunction finally induced acute pancreatitis, pancreatic cancer and other diseases. In addition, mitochondrial homeostasis plays an indispensable role in maintaining the normal function of islet cells. This paper reviewed the research status of mitochondrial dysfunction in pancreatic diseases.

ObjectiveTo investigate the protective effect of tanshinone I (T-I) on hepatic ischemia-reperfusion injury (HIRI) in mice. MethodsA total of 36 C57BL/6J mice were randomly divided into sham-operation group, ischemia-reperfusion (IR) group, IR+T-I (5 mg/kg) group, IR+T-I (10 mg/kg) group, IR+T-I (20 mg/kg) group, and IR+T-I (40 mg/kg) group, with 6 mice in each group. Each group was given intraperitoneal injection. The mice in the sham-operation group and the IR group were injected with an equal volume of the solvent olive oil; the mice in the IR+T-I groups were administered once a day for 7 consecutive days, a model of 70% HIRI was established at 2 hours after the last administration, and serum and liver samples were collected after 6 hours of reperfusion. Related kits were used to measure the serum level of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) and the content of superoxide dismutase (SOD), malondialdehyde (MDA), caspase-3, and reduced glutathione (GSH) in liver tissue; HE staining was used to observe liver histopathology; the TUNEL method was used to measure the level of hepatocyte apoptosis; immunohistochemistry was used to measure the protein expression of caspase-3 and heme oxygenase-1 (HO-1). A one-way analysis of variance was used for comparison of continuous data between multiple groups, and the least significant difference t-test was used for further comparison between two groups. ResultsCompared with the IR group, the IR+T-I (20mg/kg) group had significant reductions in the serum levels of ALT (192.48±23.67 U/L vs 336.90±41.52 U/L, P＜0.01) and AST (123.19±9.16 U/L vs 206.90±18.81 U/L, P＜0.01), and thus 20 mg/kg was determined as the optimal concentration. Compared with the IR group, the IR+T-I (20 mg/kg) group had significant reductions in MDA (1.34±0.21 μmol/mg vs 3.48±0.95 μmol/mg, P＜0.05) and caspase-3 (0.69±0.97 μmol/mg vs 1.04±0.35 μmol/mg, P＜0.05) and significant increases in SOD (274.47±30.53 U/mg vs 160.29±27.37 U/mg, P＜0.05) and GSH (2.12±0.27 μmol/mg vs 1.03±0.42 μmol/mg, P＜0.05). HE staining showed that the IR group had disordered structure of hepatic lobules and focal or extensive degeneration and necrosis of hepatocytes; compared with the IR group, the IR+T-I (20 mg/kg) group had a reduction in the area of hepatocyte necrosis and a basically complete structure of the liver. Immunohistochemistry showed that compared with the IR group, the IR+T-I (20 mg/kg) group had significant reductions in the number of apoptotic hepatocytes and the protein expression of caspase-3 and a significant increase in the protein expression of HO-1. ConclusionT-I exerts a protective effect against HIRI in mice by inhibiting liver oxidative stress response and hepatocyte apoptosis.

Objective:To investigate mevalonic acid(MEV)on reversing the antitumor effects of fluvastatin sodium(FS)on tongue squamous cell carcinoma(TSCC)cells.Methods:TSCC HSC-4 cells were treated with different concentrations of FS and MEV re-spectively or in combination.Cell counting kit-8,flow cytometry,wound healing,immunofluorescence and western blotting assays were conducted to examine cell proliferation,apoptosis and migration capacities,as well as the expression levels of Ras homolog family member A(RHOA),tissue factor(TF)and B-cell lymphoma-2-associated X(BAX)proteins,respectively.Results:FS inhibited HSC-4 cell proliferation and migration,decreased the expression of RHOA and TF,and increased BAX expression.MEV reversed the above antitumor effects of FS and promoted intracellular RHOA and TF expression.Conclusion:MEV reverses the antitumor effects of FS on HSC-4 cells in vitro.

OBJECTIVETo prepare cisPLLAtin-loaded polylactic acid/cnts, and to study the anti-tumor effect of 5-FU-PLLA-CNTs on human gastric carcinoma cell lines(MGC803 and MNK45).

METHODS5-FU-PLLA-CNTs were prepared with ultrasound emulsification. The morphology of 5-FU-PLLA-CNTs was determined by scanning electron microscope(SEM), and its drug loading and drug release curve in vitro were detected by UV-Vis-NIR spectrophotometer. Cells were divided into experiment, positive control and negative control groups. CCK8 method was used to test the cytotoxic effect of 5-FU-PLLA-CNTs in different concentrations on MGC803 and MNK45 cell proliferation. Flow cytometry was employed to measure the apoptotic rate of MGC803 and MNK45 cells before and after the intervention of 5-FU-PLLA-CNTs.

RESULTSDeep layer film of 5-FU-PLLA-CNTs was successfully established, whose drug-load rate was(4.54±0.43)%, entrapment rate was(21.56±2.36)%. In vitro release test showed release rate within 24 h of 5-FU-PLLA-CNTs was 23.9% in a as lowly increasing manner, and accumulating release rate was 85.3% at day 31. CCk8 experiment revealed, as compared to control group, 5-FU-PLLA-CNTs significantly inhibited the proliferation of two cell lines in dose-dependent and time-dependent manner. The best 5-FU-PLLA-CNTs concentration of inhibition for human gastric cancer cell lines was 1 mg/well. Flow cytometry indicated the apoptotic rate of MGC803 and MNK45 cells in experiment group treated by 1 mg/well 5-FU-PLLA-CNTs significantly increased as compared to negative control group (P<0.05), while the difference was not significant as compared to positive control group (P>0.05).

CONCLUSIONThe 5-FU-PLLA-CNTs has good drug sustained-release capacity, and can significantly kill and inhibit the proliferation of MGC803 and MNK45 cell lines.

Objective:To investigate the epidemiological characteristics, diagnosis, treat-ment and prognosis of gallbladder cancer in China from 2010 to 2017.Methods:The single disease retrospective registration cohort study was conducted. Based on the concept of the real world study, the clinicopathological data, from multicenter retrospective clinical data database of gallbladder cancer of Chinese Research Group of Gallbladder Cancer (CRGGC), of 6 159 patients with gallbladder cancer who were admitted to 42 hospitals from January 2010 to December 2017 were collected. Observation indicators: (1) case resources; (2) age and sex distribution; (3) diagnosis; (4) surgical treatment and prognosis; (5) multimodality therapy and prognosis. The follow-up data of the 42 hospitals were collected and analyzed by the CRGGC. The main outcome indicator was the overall survival time from date of operation for surgical patients or date of diagnosis for non-surgical patients to the end of outcome event or the last follow-up. Measurement data with normal distribu-tion were represented as Mean±SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented as M( Q1, Q3) or M(range), and com-parison between groups was conducted using the U test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test. Univariate analysis was performed using the Logistic forced regression model, and variables with P<0.1 in the univariate analysis were included for multivariate analysis. Multivariate analysis was performed using the Logistic stepwise regression model. The life table method was used to calculate survival rates and the Kaplan-Meier method was used to draw survival curves. Log-rank test was used for survival analysis. Results:(1) Case resources: of the 42 hospitals, there were 35 class A of tertiary hospitals and 7 class B of tertiary hospitals, 16 hospitals with high admission of gallbladder cancer and 26 hospitals with low admission of gallbladder cancer, respectively. Geographical distribution of the 42 hospitals: there were 9 hospitals in central China, 5 hospitals in northeast China, 22 hospitals in eastern China and 6 hospitals in western China. Geographical distribution of the 6 159 patients: there were 2 154 cases(34.973%) from central China, 705 cases(11.447%) from northeast China, 1 969 cases(31.969%) from eastern China and 1 331 cases(21.611%) from western China. The total average number of cases undergoing diagnosis and treatment in hospitals of the 6 159 patients was 18.3±4.5 per year, in which the average number of cases undergoing diagnosis and treatment in hospitals of 4 974 patients(80.760%) from hospitals with high admission of gallbladder cancer was 38.8±8.9 per year and the average number of cases undergoing diagnosis and treatment in hospitals of 1 185 patients(19.240%) from hospitals with low admission of gallbladder cancer was 5.7±1.9 per year. (2) Age and sex distribution: the age of 6 159 patients diagnosed as gallbladder cancer was 64(56,71) years, in which the age of 2 247 male patients(36.483%) diagnosed as gallbladder cancer was 64(58,71)years and the age of 3 912 female patients(63.517%) diagnosed as gallbladder cancer was 63(55,71)years. The sex ratio of female to male was 1.74:1. Of 6 159 patients, 3 886 cases(63.095%) were diagnosed as gallbladder cancer at 56 to 75 years old. There was a significant difference on age at diagnosis between male and female patients ( Z=-3.99, P<0.001). (3) Diagnosis: of 6 159 patients, 2 503 cases(40.640%) were initially diagnosed as gallbladder cancer and 3 656 cases(59.360%) were initially diagnosed as non-gallbladder cancer. There were 2 110 patients(34.259%) not undergoing surgical treatment, of which 200 cases(9.479%) were initially diagnosed as gallbladder cancer and 1 910 cases(90.521%) were initially diagnosed as non-gallbladder cancer. There were 4 049 patients(65.741%) undergoing surgical treatment, of which 2 303 cases(56.878%) were initially diagnosed as gallbladder cancer and 1 746 cases(43.122%) were initial diagnosed as non-gallbladder cancer. Of the 1 746 patients who were initially diagnosed as non-gallbladder cancer, there were 774 cases(19.116%) diagnosed as gallbladder cancer during operation and 972 cases(24.006%) diagnosed as gallbladder cancer after operation. Of 6 159 patients, there were 2 521 cases(40.932%), 2 335 cases(37.912%) and 1 114 cases(18.087%) undergoing ultrasound, computed tomography (CT) or magnetic resonance imaging (MRI) examination before initial diagnosis, respec-tively, and there were 3 259 cases(52.914%), 3 172 cases(51.502%) and 4 016 cases(65.205%) undergoing serum carcinoembryonic antigen, CA19-9 or CA125 examination before initially diagnosis, respectively. One patient may underwent multiple examinations. Results of univariate analysis showed that geographical distribution of hospitals (eastern China or western China), age ≥72 years, gallbladder cancer annual admission of hospitals, whether undergoing ultrasound, CT, MRI, serum carcinoembryonic antigen, CA19-9 or CA125 examination before initially diagnosis were related factors influencing initial diagnosis of gallbladder cancer patients ( odds ratio=1.45, 1.98, 0.69, 0.68, 2.43, 0.41, 1.63, 0.41, 0.39, 0.42, 95% confidence interval as 1.21-1.74, 1.64-2.40, 0.59-0.80, 0.60-0.78, 2.19-2.70, 0.37-0.45, 1.43-1.86, 0.37-0.45, 0.35-0.43, 0.38-0.47, P<0.05). Results of multivariate analysis showed that geographical distribution of hospitals (eastern China or western China), sex, age ≥72 years, gallbladder cancer annual admission of hospitals and cases undergoing ultrasound, CT, serum CA19-9 examination before initially diagnosis were indepen-dent influencing factors influencing initial diagnosis of gallbladder cancer patients ( odds ratio=1.36, 1.42, 0.89, 0.67, 1.85, 1.56, 1.57, 0.39, 95% confidence interval as 1.13-1.64, 1.16-1.73, 0.79-0.99, 0.57-0.78, 1.60-2.14, 1.38-1.77, 1.38-1.79, 0.35-0.43, P<0.05). (4) Surgical treatment and prognosis. Of the 4 049 patients undergoing surgical treatment, there were 2 447 cases(60.435%) with complete pathological staging data and follow-up data. Cases with pathological staging as stage 0, stage Ⅰ, stage Ⅱ, stage Ⅲa, stage Ⅲb, stage Ⅳa and stage Ⅳb were 85(3.474%), 201(8.214%), 71(2.902%), 890(36.371%), 382(15.611%), 33(1.348%) and 785(32.080%), respectively. The median follow-up time and median postoperative overall survival time of the 2 447 cases were 55.75 months (95% confidence interval as 52.78-58.35) and 23.46 months (95% confidence interval as 21.23-25.71), respectively. There was a significant difference in the overall survival between cases with pathological staging as stage 0, stage Ⅰ, stage Ⅱ, stage Ⅲa, stage Ⅲb, stage Ⅳa and stage Ⅳb ( χ2=512.47, P<0.001). Of the 4 049 patients undergoing surgical treatment, there were 2 988 cases(73.796%) with resectable tumor, 177 cases(4.371%) with unresectable tumor and 884 cases(21.833%) with tumor unassessable for resectabi-lity. Of the 2 988 cases with resectable tumor, there were 2 036 cases(68.139%) undergoing radical resection, 504 cases(16.867%) undergoing non-radical resection and 448 cases(14.994%) with operation unassessable for curative effect. Of the 2 447 cases with complete pathological staging data and follow-up data who underwent surgical treatment, there were 53 cases(2.166%) with unresectable tumor, 300 cases(12.260%) with resectable tumor and receiving non-radical resection, 1 441 cases(58.888%) with resectable tumor and receiving radical resection, 653 cases(26.686%) with resectable tumor and receiving operation unassessable for curative effect. There were 733 cases not undergoing surgical treatment with complete pathological staging data and follow-up data. There was a significant difference in the overall survival between cases not undergoing surgical treatment, cases undergoing surgical treatment for unresectable tumor, cases undergoing non-radical resection for resectable tumor and cases undergoing radical resection for resectable tumor ( χ2=121.04, P<0.001). (5) Multimodality therapy and prognosis: of 6 159 patients, there were 541 cases(8.784%) under-going postoperative adjuvant chemotherapy and advanced chemotherapy, 76 cases(1.234%) under-going radiotherapy. There were 1 170 advanced gallbladder cancer (pathological staging ≥stage Ⅲa) patients undergoing radical resection, including 126 cases(10.769%) with post-operative adjuvant chemotherapy and 1 044 cases(89.231%) without postoperative adjuvant chemo-therapy. There was no significant difference in the overall survival between cases with post-operative adjuvant chemotherapy and cases without postoperative adjuvant chemotherapy ( χ2=0.23, P=0.629). There were 658 patients with pathological staging as stage Ⅲa who underwent radical resection, including 66 cases(10.030%) with postoperative adjuvant chemotherapy and 592 cases(89.970%) without postoperative adjuvant chemotherapy. There was no significant difference in the overall survival between cases with postoperative adjuvant chemotherapy and cases without postoperative adjuvant chemotherapy ( χ2=0.05, P=0.817). There were 512 patients with pathological staging ≥stage Ⅲb who underwent radical resection, including 60 cases(11.719%) with postoperative adjuvant chemotherapy and 452 cases(88.281%) without postoperative adjuvant chemotherapy. There was no significant difference in the overall survival between cases with postoperative adjuvant chemo-therapy and cases without post-operative adjuvant chemo-therapy ( χ2=1.50, P=0.220). Conclusions:There are more women than men with gallbladder cancer in China and more than half of patients are diagnosed at the age of 56 to 75 years. Cases undergoing ultrasound, CT, serum CA19-9 examination before initial diagnosis are independent influencing factors influencing initial diagnosis of gallbladder cancer patients. Preoperative resectability evaluation can improve the therapy strategy and patient prognosis. Adjuvant chemotherapy for gallbladder cancer is not standardized and in low proportion in China.
