Community health service is an effective measure to relieve the difficult medical services and expensive medical cost problem,but community inhabitants in Chongqing make little use of community health service.The actual cause is that people s degree of trust in community health service is low.In view of existing situation,this article analyzes the various factors that influence community residents' degree of trust in community health service and puts forward corresponding policy proposal.

AIM: To observe the mRNA expressions of Insulin-induced gene 2(Insig-2) and Vitamin D receptor(VDR) in HepG2 cell line and investigate the possible mechanism of berberine on regulating blood lipid. METHODS: HepG2 cells were incubated with Bet at different concentrations(1,3,10,30,100 ?mol/L),and incubated with 3 ?mol/L berberine for various times(0,12,24,48,72 h).Total RNA was extracted and the mRNA expressions of Insig-2 and VDR from HepG2 cells treated by berberine were quantified by RT-PCR.(RESULTS): After exposure to gradient concentrations of berberine for 24 h,the mRNA expressions of Insig-2 and VDR in HepG2 cells increased obviously peaked at 3 ?mol/L concentration,then the up-regulating effect declined gradually.The relative coefficient between them was(0.753)(P

BACKGROUND:There is no doubt that animal model of fracture is the basis of fracture healing research.The fracture animal mode is divided into open osteotomy model and closed fracture model.There is no research about the difference between two kinds of fracture rat models.OBJECTIVE:To compare the modeling process between open osteotomy model and closed fracture model in rats,and to compare fracture healing using radiograph.DESIGN,TIME AND SETTING:The randomized,controlled animal experiment was performed at the Laboratory of Department of Orthopaedics,Second Affiliated Hospital,Soochow University from January to May 2007.MATERIALS:A total of 40 SPF male Sprague Dawley rats,weighing(220?30) g,were randomly divided into an open osteotomy model group and a closed fracture model group,with 20 rats for each group.Electric swing saw was a kind of self-made percussion device for closed fracture models.METHODS:All rats in the open osteotomy model group received open osteotomy to create transverse fracture of the middle femur,and fixed using Kirschner wire.Rats in the closed fracture model group received retrograde Kirschner wire fixation,and midshaft femoral closed fracture induced by model establishment stent.MAIN OUTCOME MEASURES:Mean model establishment time;Successful rate of model establishment;Radiography of fracture healing at 2,3,4 and 8 weeks after surgery.RESULTS:Success rate of open osteotomy model establishment was 90%.Average modeling time was 17 minutes.Rate of malunion and nonunion was 40%.Successful rate of each closed fracture models was 85%,with average modeling time was 12 minutes.There was no malunion and nonunion.At 2,3 and 4 weeks after surgery,X-ray score was lower in the open osteotomy model group compared with the closed fracture model group(P 0.05).CONCLUSION:Model establishment of open osteotomy takes a longer time,with a high rate of malunion and nonunion.In near future or medium-term,fracture healing is significantly lagged.Thus,open osteotomy is not suitable for the study of early or medium-term fracture healing.

OBJECTIVE To understand epidemiologic situation of pathogens causing nosocomial infection,their resistance and changing pattern.METHODS A retrospective analysis was made upon the pathogens data from 2002 to 2006.The identification of bacteria was evaluated by VITEK32 and susceptibility test by K-B method.RESULTS The prevalence rate was 6.4%,and main infection sites were lower respiratory tract and urinary tract.Gram-negative bacteria(38.11%) stood first,followed by Gram-positive bacteria(25.25%) and fungi(22.54%).The mean resistance of Gram-negative bacteria was very high,from them Stenotrophomonas maltophilia(72.71%) and Chryseobacterium meningosepticum(68.13%) stood the highest.Besides Enterococcus faecalis,the mean resistance of Gram-positive bacteria exceeded 55.00%.Candida albicans stood first on the list of fungi.CONCLUSIONS The composition of pathogens is changing and showing serious resistances.It is important to strengthen nosocomial infection management and utilize drug rationally.

OBJECTIVE:To provide reference for benign sustainable development of traditional Chinese and ethnic medicine enterprises in Guizhou. METHODS:Taking 129 traditional Chinese and ethnic medicine enterprises of 9 city and prefecture in Gui-zhou as survey object,questionnaires survey was conducted in 55 enterprises by stratified sampling according to location. The data statistical analysis was carried out in respects of related policies familiarity,product positioning,independent innovation from 2009 to 2013. Relevant development countermeasures were put forward. RESULTS & CONCLUSIONS:45.1% of enterprises ex-pressed to know and be familiar with relevant policies,51.0% expressed to alert but only understand,and 3.9% said largely un-known. At the past five years,the annual output value and sales revenue of enterprises had risen year by year. Almost 80% produc-tion and technical personnel of enterprises had the junior title or no title;marketing department staff mainly had college and second-ary school degree,accounting for 47.5% and 25.3% respectively;research personnel mainly had bachelor and college degree,ac-counting for 57.0% and 33.7% respectively. At the past five years,independent innovation input took up 2.4% of sales revenue av-eragely. There are problems,such as small and medium enterprises occupying dominate position;enterprises lacking of sufficient understanding on related policies;strategies being adjusted slowly;independent innovation input intensity needing to increase. Countermeasures and suggestions are put forward,such as strengthening the relevant policy advocacy,guiding corporate mergers and acquisitions,closely paying attention to industry development,changing innovation ideas,and attaching importance to research of exclusive production of essential medicine.

Objective To investigate the clinical effectiveness of fast track surgery ( FTS) nursing during laparoscopic cone-shaped resection of renal tumor. Methods Forty patients who was planned to accept laparoscopic cone-shaped renal tumor resection was divided into either FTS group ( n=20 ) or control group ( n=20 ) according to odd-even number of their admission IDs. The control group was given routine perioperative nursing procedure, and the FTS group was given FTS nursing. Results The operation time, intraoperative blood loss and incidence of complications had no statistical significance between the two groups (P>0. 05). As compared to the control group, patients in the FTS group experienced a shorter anal exhaust time [(30. 3 ± 11. 7) h vs. (43. 0 ± 15. 5) h, t= -2. 924, P=0. 006], shorter post-operative fasting time [(26. 6 ± 12. 1) h vs. (56. 1 ± 18. 1) h, t= -6. 059, P=0. 000], earlier ambulation [(33. 6 ± 16. 8) h vs. (66. 9 ± 28. 6) h, t= -4. 490, P=0. 000], shorter urethral catheterization [(40. 2 ± 18. 5) h vs. (83. 4 ± 39. 6) h, t= -4. 420, P=0. 000], shorter drainage time [(50. 3 ± 22. 5) h vs. (102. 9 ± 46. 0) h, t= -4. 594, P=0. 000], and shorter length of hospitalization [(5. 5 ± 1. 5) d vs. (9. 0 ± 2. 1) d, t= -5. 911, P=0. 000]. Conclusions FTS nursing procedure can reduce the rate of post-operative complications and shorten hospitalization stay. It can not only guarantee the efficacy of surgical treatment but also help the patient to achieve the goal of fast rehabilitation, being worthy of extensive application.

BACKGROUND:Bone marrow mesenchymal stem cells have beneficial effects on the treatment of various diseases. Mitochondria transfer is newly proposed and its specific mechanisms of action and control factors remain unclear.
OBJECTIVE:To review the studies about stem cells and mitochondrial transfer, then to discuss its value on clinical.
METHODS:The PubMed, VIP and Wanfang databases were searched for related articles concerning stem cells and mitochondrial transfer. Key words were“stem cell, embryonic stem cell, progenitor cell, mitochondria”in Chinese and“Stem cell[s], Mother cell[s], Progenitor cell[s], Colony-Forming Unit[s], Colony Forming Unit[s], Mitochondria[l] transfer”in English. Thirteen articles were found initial y, and using the citation tracking method, final y 42 articles were determined. RESULTS AND CONCLUSION:Studies have shown that mitochondrial transfer from bone marrow mesenchymal stem cells is associated with rescue of aerobic respiration and restoration of mitochondrial function in the injured somatic cells. Bone marrow mesenchymal stem cells and recipient cells form tunneling nanotubes for mitochondrial transfer. Movement of mitochondria between cells is regulated and directed by Miro1. The successful transfer of mitochondria may be accompanied with the clearance of damaged mitochondria. The rescue of mitochondrial function in early stages may provide a valuable therapeutic strategy for various diseases include acute lung injury.

Objective To investigate effects of early administration of high-dose rosuvastatin(40 mg) on coronary microvascular function and short-term outcome in patients treated with primary percutaneous coronary intervention (PCI) for acute myocardial infarction(AMI). Methods Ninety-four consequent AMI patients treated with primary PCI were divided into rosuvastatin group (50 patients) and control group (44 group). The infarct-related artery flow of epicardium was classified in compliance with the TIMI criteria. Myocardial and microvascular perfusion was assessed using the TMPG. The incidence of the MACE and the cytotoxicity and hepatotoxicity of rosuvastatin was respectively recorded in 30 d follow-up period. Results Either patients in the rosuvastatin group or in the control group showed better TMPG immediately after PCI (P<0.05), compared with that before treatment. However, the post-PCI TMPG of the rosuvastatin group was obviously much better than that of control group (P<0.05). Compared with that in control group, the 30-day composite MACE rate was lower in rosuvastatin group and in the TMPG 3 patients of rosuvastatin group:12.0%(6/50) vs. 34.1%(15/44), P<0.05;11.1%(3/27) vs. 42.9%(6/14). There was no cytotoxicity and hepatotoxicity in two groups. Conclusions Early administration of high-dose rosuvastatin (40 mg) can improve coronary microvascular function and short-term outcome in patients treated with primary PCI for AMI, and it is efficient and safety.
