ObjectiveTo observe the therapeutic efficacy ofacupoint thread embedding in treating hyperlipidemia, and to explore a treatment method with valid efficacy and few side effects.MethodSixty patients with hyperlipidemia were randomized into a thread embedding group and a medication group, 30 cases ineach group. The thread embedding group was intervened by thread embedding at Zhongwan (CV12), Tianshu (ST25), Fenglong (ST40), and Zusanli (ST36), once a week; the medication group was by taking Xue Zhi Kang capsules, two capsules each time, twice a day. The two groups both received treatment for 8 weeks. The clinical efficacy, total cholesterol (Chol), and triglyceride levels were observed before and after treatment.ResultThe total effective rate was 86.7% in the thread embedding group versus 83.3% in the medication group, and the difference was statistically insignificant (P>0.05). After 4-week treatment, the transaminase level increased in 3.3% of the patients in the medication group, while no one showed an increased transaminase level in the thread embedding group. After 8-week treatment, the observed indexes were increased in the medication group, while those in the thread embedding group were still stable.ConclusionAcupoint thread embedding is effective in treating hyperlipidemia, and the effect is durable with few side effects.

Purpose:To study the RNA interference-mediated inhibition of survivin gene on the proliferation of human breast cancer SKBr-3 cells. Methods:SKBr-3 cells were transfected with a pSUPER-S1 vector plasmid that expressed survivin-targeted small interfering RNA, and the mRNA and protein levels of survivin gene were measured with RT-PCR and indirect immunofluorescence, respectively. The proliferation of transfected SKBr-3 cells was investigated through colony forming assay and MTT assay. The cell cycle phases were determined by flow cytometry(FCM). Results:The mRNA and protein levels of survivin declined markedly in pSUPER-S1-transfected SKBr-3 cells. And the colony forming rate of those cells(38?16.70)% was significantly lower than that of the control cells(90.3?4.04)%.The growth of the pSUPER-S1-transfected cells was decelerated and the cell cycle was mainly blocked at G_(1) phase(74.03?8.91)%. Conclusions:survivin gene silencing by RNA interference contributed to a distinctive inhibition of the proliferation of human breast cancer SKBr-3 cells in vitro.

Objective To study the inhibitory effect of arsenic trioxide(AS2O3)on the tumor growth of breast cancer line MDA-MB-435s implanted subcutaneously in nude mice and its mechanism.Methods BALB/C-nu/nu nude mice were subcutaneously injected with MDA-MB-435s breast cancer cells that are ER-positive,and treated with intraperitoneal injection of AS2O3 and DDP in different concentrations.The implanted tumor was weighed,and tumor inhibition rates were calculated.The expression of PTEN and Caspase-7 induced by AS2 03 were examined by immunohistochemical method.Results The growth of implanted tumor was markedly inhibited with DDP,low dose and high dose AS2O3,and the inhibitory rates were 48.68%,32.80%,66.67%respectively.The immunohisto chemical staining showed that the number of PTEN and Caspase-7 protein increased markedly(P＜0.05).Conclu sions AS2O3 inhibits the growth of human breast cancer cell implanted tumor.The molecular mechanism of AS2O3 on induction of apoptosis of breast cancer cells may be throush increasing the expression of PrrEN and Caspase-7(P ＜0.05).

Objective To investigate the change rule and correlation of heme oxygenase-1(HO-1)/carbon monoxide(CO)and the influence of simvastatin and amlodipine in athemsclemtic progress.Methods The rabbits received 1％cholesterol diet(n=24)for eight weeks.After eight weeks,rabbits were fed with normal diet for eight weeks.The rabbits in model group(n=8)were administrated with cholesterol diet.The rabbits in simvastatin group(n=8)were administrated with simvastatin.The rabbits in amlodipine group(n=8)were administrated with amlodipine.The levels of serum lipids and plasma carbon monoxide were obtained at the beginning,the 8th week and the 16th week.The expression of heme oxygenase-1 in the thoraoia aortic tissue were observed with immunohistochemistry technique.Results By the end of 16th week,the levels ofserum lipids and plasma carbon monoxide in model group were obviously increased,however,the expression of heine oxygenase-1 were markedly decreased.Compared with model group.The levels～rurfl lipi&and plasma carbon monoxide in simvastatin group were significantly decreased,while the expression of heme oxysenase-1 in aortic great reduced.The levels flerum lipids in amlodipine group were not significant ckmged,the levels of plasma carbon monoxide were obviously decreased,while tlle expression ofheine oxygenase-1 in aortic great reduced.Conclusions In atheresclerofic progress,heme oxygenase-1(HO-1)/carbon monoxide(CO)appared the reciprocal relationship,and amlodipine may suppress athemsclemtie progress by decreasing the system.

Objective To understand the status and the influencing factors of urban and rural elderly housebound in western region of China. Methods Two urban communities and two towns were selected from Chengdu and Lanzhou. A total of 2 584 elderly meeting the conditions were selected for investigation (including demographic data, living habits, physical condition, environmental, psychological, social status, housebound state rating scale, etc.) by method of going to home one by one. Results The incidence of community elderly housebound was 18.85% (487/2 584) in the western region. Multivariate regression analysis showed that other occupation (farmers, self-employed, free occupation, no industry etc.), no drinking, no exercise, no communication with neighbors, poor daily activities were the main factors affecting the occurrence of housebound. Conclusions The western region of community elderly housebound is higher, we should take appropriate measures to prevent the occurrence and deterioration of housebound.

Objective To understand the distribution and antimicrobial resistance of pathogenic bacteria isolated from patients in the department of infectious diseases in Xiangya Hospital.Methods The distribution and antimicrobial susceptibility testing results of pathogenic bacteria isolated from patients in this department in 2011 -2015 were analyzed retrospectively.Results A total of 560 strains were isolated during 5 years,of which gram-posi-tive bacteria and gram-negative bacteria accounted for 44.1 % (n =247)and 55.9%(n =313)respectively.69.8%(81/116)of coagulase-negative staphylococcus and 24.3%(9/37)of Staphylococcus aureus were methicillin-resistant (MRCNS,MRSA)respectively.Enterococcus was highly susceptible to vancomycin,linezolid,and phosphonomy-cin (>81 %).Enterobacteriaceae remained highly susceptible to carbapenems (88.9%-100.0%),and was suscep-tible to amikacin,cefoperazone/sulbactam,and piperacillin/tazobactam (>84%).Acinetobacter baumannii was the major isolated multidrug-resistant organism (MDRO),isolation rate of imipenem-resistant Acinetobacter baumannii increased from 50.0% in 2011 to 77.8% in 2015,its resistance rate to imipenem was 64.9%.Conclusion The majority of clinically isolated pathogenic bacteria from this department is gram-negative bacilli,and detection rate of MDROs showed an upward trend;antimicrobial agents should be chosen according to distribution and antimicrobial resistance of pathogenic bacteria.

Background and purpose:More and s’more evidence has demonstrated that DNMT1 was expressed at high levels in many different kinds of human tumor tissues or cells,suggesting that high expression of DNMT1 was closely associated with occurrence and development of tumors.In this study,effect of down-regulation of DNMT1 on cell proliferation and migration ability of esophageal squamous cell carcinoma(ESCC) cell line EC9706 cells was studied and its related mechanism was explored.Methods:Cell proliferation assay was investigated using CCK-8 Kit,cell migration ability was analyzed using Boyden chamber and the expressions of DNMT1 and MMP-2 were detected by Real-time PCR and Western blotting methods.Results:The result of cell proliferation experiment showed that down-regulation of DNMT1 could markedly inhibit cell proliferation in EC9706 cells.After transfection with DNMT1 siRNA,invasiveness and metastasis ability of EC9706 cells displayed an obvious decrease(P
