Background:Esophageal cancer is a common gastrointestinal cancer with poor prognosis,and effective chemotherapy is lacking currently. Studies have shown that cardiac glycosides can inhibit tumor cells growth,but its mechanism has not been fully clarified. Aims:To investigate the effect and mechanism of ouabain in regulating proliferation of human esophageal carcinoma cells. Methods:OE19 human esophageal carcinoma cells were treated with ouabain,and cells in control group were treated with DMSO. Cell proliferation was assessed by cell counting method. mRNA expressions of Sox2,Sox4,Sox7,Sox9 and Sox10 were determined by real-time PCR. Protein expression of Sox4 was determined by Western blotting. Gene expressions of phospho-histone3( ph3),a cell proliferation marker and Sox4 were detected by immunofluorescence staining. Results:Ouabain( ≥ 40 nmol/ L)could significantly inhibit OE19 cells proliferation. mRNA and protein expressions of Sox4 were significantly decreased in OE19 cells in ouabain(40 nmol/ L)group than those in control group(P < 0. 05). No significant differences in mRNA expressions of Sox2,Sox7,Sox9 and Sox10 were found between the two groups(P > 0. 05). Gene expressions of ph3 and Sox4 in nucleus of OE19 cells were decreased in ouabain (40 nmol/ L)group than those in control group. Conclusions:Ouabain is effective in inhibiting human esophageal carcinoma cells proliferation,the underlying mechanism might be related with down-regulation of Sox4 expression and the subsequent cell cycle modulation.

Objective To investigate the clinical and epidemiological characteristics of osteosarcoma in China and analyze the incidence and clinical treatment of osteosarcoma.Methods The clinical data of 1 593 patients with osteosarcoma in 7 bone cancer treatment centers from January 2000 to February 2017 were analyzed.We retrieved large samples of documents in the database,extracted the relevant data and compared the data with this study.SPSS 13 software was used for statistical analysis and each factor was tested by x2.Results Of 1 593 patients,984 were males and 609 were females.The ratio of male to female was 1.62∶ 1.The average age was 23.2 years (range from 3-80 years).The peak age of onset was 11-20 years (52.4％).There were 217 elderly patients (＞ 40 years old).The tumors occurred in 1 524 limbs and 69 in axial bone.The most common sites of disease were distal femur 706 cases,proximal tibia 375 cases,distal humerus 117 cases and others 395 cases.There were 1 154 cases (71％) around the knee joint.The axial bone included 18 cases of spine,49 cases of pelvis and 2 cases of rib.Preoperative biopsy was performed in 1 111 cases and incisional biopsy in 280 cases.Preoperative diagnosis could be made in 1 345 cases (84.4％ of all patients,accounting for 96.7％ of biopsy patients).There were 79 cases with metastasis at first visit,accounting for 5％.Preoperative chemotherapy was performed in 1 185 cases (74.4％).With the DIA preoperative chemotherapy 271 cases,DIA+MTX 251 cases,AP 149 cases.220 cases of tumor cell necrosis rate was evaluated after operationaccording to the Huvos classification.There were78 cases of grade Ⅰ,105 cases of Ⅱ grade,35 cases of Ⅲ and 2 cases of grade Ⅳ.There were 1 299 cases undergoingpostoperative chemotherapy (81.5％),1 306 patients undergoinglimb salvage surgery (82％).Thespecific operation with prosthetic replacement is the most common (911 cases,69.8％).The postoperative chemotherapy included DIA+MTX regimen 471 cases,DIA regimen 266 cases and AP regimen 98 cases.Before and after the operation,379 cases were treated with the same chemotherapy regimen and 666 cases were changed.A total of 18 large sample documents were retrieved in Chinese data base (5 684 cases).The sex ratio,age range,peak incidence and location of the disease were similar to those of this study.The average age was 1-2 years old younger.The percentage of lung metastases associated with initial visits washigher.The rate of preoperative and postoperative chemotherapy and limb salvage waslowand the rate of tumor necrosis wasbetter after chemotherapy.A total of 22 large sample literatures were searched in foreign database (12 850 cases).The ratio of men and women is 1.30∶1 and the proportion of women is higher than the domestic data.The average age was 1-2 years older.The ratio of the knee joint was lower.The percentage of lung metastases associated with initial visits washigher.The rate of preoperative and postoperative chemotherapy and limb salvage were similar to that of this study and the rate of tumor necrosis was better after chemotherapy.Conclusion The general situation of the incidence of osteosarcoma (sex,age,location of the disease) is not significantly different from the previous reports both at home and abroad.In the treatment,preoperative and postoperative chemotherapy rate and limb salvage surgery rate have improved significantly compared with the past.The chemotherapy program from the coexistence of various programs,gradually to the DIA+MTX and DIA program as the mainstream program.

Objective To evaluate the applicability of the Chinese version of SF-36 ( v. 2 ) scale for evaluating the quality of life of hospitalized patients with chronic heart failure. Methods From September 2013 to December 2014, 159 patients with chronic heart failure(NYHA I-IV), who were older than 18 years, clear mind and well self-expressed, were selected as participants. Questionnaire surveys included general survey and SF-36(v. 2) scale. Internal consistency reliability, binary reliability and construct validity were all analyzed as indicators to evaluate SF-36 ( v. 2 ) scale. Results A total of 159 questionnaires were issued and 159 valid questionnaires were recovered. The eight dimensions of SF-36(v. 2) scale including physical function (PF), role-physical (RP), bodily pain (BP), general health (GH), social function (SF), vitality (VT), role-emotion(RE), and mental health (MH) score conversion were (41.57 ±24.86), (48.35 ±21.64), (69.18 ± 25. 68), (31. 28 ± 16. 01), (48. 90 ± 19. 53), (45. 05 ± 22. 76), (59. 43 ± 24. 31), (57. 55 ± 19. 03); the floor effects were 2. 5%, 4. 4%, 3. 1%, 4. 4%, 3. 1%, 6. 3%, 0. 6%, 1. 3%; the ceiling effects were 0. 0%, 3. 8%, 21. 4%, 0. 0%, 0. 0%, 1. 9%, 3. 1%, 0. 0%. The item-convergent validity all achieved the standard (r≥0. 4), and the total scaling success rate of item-convergent was 100. 00%; the dimensions′success rates of item-discriminant validity of RP, BP, RE and SF were all 100%, the rest of four dimensions were PF 95. 71%, GH 85. 71%, VT 89. 29%, MH 94. 29%, and the total success rate was 94. 69%. Internal consistency reliability ranged from 0. 738 to 0. 919; the binary reliability ranged from 0. 808 to 0. 963. Within factors analysis, two common factors were confirmed, separately representing physical health and mental health, altogether making contribution of 61. 66% cumulative variance. Conclusions As the revision of SF-36(v. 1), SF-36(v. 2) scale seemed more friendly in layout for questions and answers, the floor and ceiling effects significantly reduced. Additionally, it also shows good reliability and validity in the evaluation of quality of life of hospitalized patients with chronic heart failure, and the SF-36(v. 2) scale can be used to evaluate the quality of life ( QOL) of patients with chronic heart failure.

Objective To explore the clinical efficacy of low molecular weight heparin combined with insulin in the treatment of hyper-triglyceridemic-acute pancreatitis(HTG-AP).Methods A total of 106 patients diagnosed with HTG-AP who were admitted to the department of gastroenterology of Huaibei People's Hospital from May 2022 to July 2023 were selected as the research objects.According to the random number table method,the low-molecular heparin group(35 cases,received a 5 000 U subcutaneous injection low-molecular heparin once every 12 hours for 6 days),the insulin group(35 cases,received intravenous insulin pumping at a rate of 2 U/h,with careful monitoring of the patient's random blood glucose levels to prevent hypoglycemia),and the combination therapy group(36 cases,received both low-molecular heparin and insulin).Before treatment and at 1,2,and 6 days after treatment,the difference of serum triacylglycerol(TG),total cholesterol(TC),blood amylase,inflammatory factors[C-reactive protein(CRP),interleukin-6(IL-6)],calcium ions,and creatinine levels among the three groups were compared.The modified computed tomography severity index(MCTSI)scores,acute physiology and chronic health evaluationⅡ(APACHEⅡ),hospital length of stay,and hospital costs before and after 6 days of treatment were observed.Results After treatment,the TC of all three groups significantly decreased compared to before treatment(P<0.05),but there was no significant difference among the three groups.The calcium ion levels of the three groups did not show a statistically significant difference before and after treatment.After 6 days of treatment,the creatinine levels of the three groups significantly decreased compared to before treatment,but there was no significant difference among the three groups.After 2 days of treatment,serum TG levels were significantly lower in the combination therapy group and insulin group compared to the low-molecular heparin group(mmol/L:4.6±1.7,4.4±1.8 vs.5.6±2.0,both P<0.05).However,there was no statistically significant difference between the combination therapy group and the insulin group.After 6 days of treatment,the combination therapy group showed significantly lower levels of serum TG,blood amylase,CRP,and IL-6 compared to the insulin group and the low-molecular heparin group[TG(mmol/L):2.8±1.9 vs.4.3±1.9,5.0±2.2,blood amylase(U/L):36.0(32.0,45.0)vs.59.0(43.0,71.0),52.0(45.0,64.0),CRP(mg/L):12.9(8.8,29.7)vs.35.3(21.7,50.3),31.4(23.0,45.1),IL-6(ng/L):15.4(9.8,23.5)vs.25.6(16.4,51.5),32.9(14.7,41.4),all P<0.05].After 6 days of treatment,the APACHEⅡscores of all three groups decreased significantly(all P<0.05).The MCTSI scores of the insulin group and the combined treatment group also decreased significantly compared to before treatment.Furthermore,the MCTSI and APACHEⅡscores of the combination therapy group were significantly lower than those of the low-molecular heparin group and the insulin group(MCTSI score:2.3±0.7 vs.3.3±1.7,2.9±1.3,APACHEⅡscore:1.3±1.2 vs.2.5±2.4,2.6±2.5,all P<0.05).The combination therapy group had significantly lower length of hospital stay and treatment cost compared to the low molecular heparin and insulin groups[length of hospital stay(days):6.9±1.6 vs.8.8±3.4,8.5±2.8,and cost of treatment(yuan):6 040.5(5 239.4,7 105.9)vs.6 696.4(5 791.5,11 026.2),6 918.5(6 087.9,10 080.8),all P<0.05].Conclusions The combination of low-molecular heparin and insulin treatment can significantly reduce serum TG and inflammatory factor levels,as well as the severity and duration of the disease.This approach can also reduce the cost of treatment.Therefore,it is worth promoting and applying in clinical settings.
