In order to study the disease occurrence , developments and changes in a hospital and the sur -rounding area, statistical analysis of outpatient and inpatient diseases and medical expense from 2008 ~2013 in the hospital was made.According to the analysis results, the principal diseases of outpatient are infectious disease and chronic disease.Dry -eye incidence has been increasing rapidly in the past 6 years, and the medical expenses in-creased significantly, and attention should be paid on it.Among the inpatient diseases , pregnancy, childbirth and puerperium complications consistently rank the first .This is the reason why the highest proportion is around the age of 20 ~39 years old and among the woman sufferers, but in the inpatient disease spectrum , the constituent ratio appears a decrease trend year by year, meanwhile, genitourinary system disease, respiratory system disease, circulation sys-tem disease and tumor show the upward trend year by year .Therefore, the proportion of self -pay medical expenses of patients is still high, and the financial burden is heavy .Hence the construction of medical security system needs to be continually strengthened.

The concept of “disease prevention theory” contains a wealth of preventive medicine thought. Pre-ventive health care service in Traditional Chinese Medicine( TCM) is an important measure for enhancing health qual-ity and improving the quality of living. This contributes to the building of a harmonious society and suits the changing medical model. Despite a series of achievements, there are also some problems in preventative health care service. Based on an analysis of influencing factors on policy implementation, the problems are discussed in the paper. The study provides some suggestions on preventive health care services, including the perfection of operations and man-agement mechanisms, the improvement of awareness on preventive health care service, the strengthening of the talent team, an increase in funding, and an evaluation of policy implementation.

Objective To construct pEGFP-C2-AQP4-M23 plasmid and to detect its expression in CTX-TNA2 cells in order to study the effect of AQP4 on astrocytes in hypoglycemia. Methods AQP4 gene obtained from SD rats by RT-PCR was cloned into pEGFP-C2 plasmid. The recombinant plasmid was transfected into CTX-TNA2 cells, then treated with low glucose. The expression and effect of AQP4 on CTX-TNA2 cells were examed with confocol. Results PCR and enzyme digestion showed AQP4 size was right; confocol demonstrated that AQP4 was expressed on the membrane of CTX-TNA2 cells, and the surfacial area of CTX-TNA2 cells with AQP4was larger than those without AQP4 in hypoglycemia. Conclusion pEGFP-C2-AQP4-M23 plasmid was successfully constructed and expressed in the CTX-TNA2 cell membrane and AQP4 plays an important role in cell edema in hypoglycemia.

Objective To explore the nursing effect evaluation of vacuum sealing drainage based latissimus dorsi bridge free skin flap to repair refractory wound. Methods Thirty-seven cases of patients with intractable wounds were chosen as the observe group from January 2009 to January 2012, and 26 cases accepting the traditional way of wound care with intractable wounds were selected as control group from January 2006 to December 2008. Control group adopt conventional methods wound and the observation group accepted VSD accessories line wound negative pressure closed drainage before the wound phase 2 latissimus dorsi bridge free skin flap repairment. After treatment, the dressing time, interval and dressing change, the time of hospitalization were observed, and the nursing effect were compared after skin flap to repair for 8 days and 16 days between patients of two groups. Results The dressing time and hospitalization days in observation group after treatment were significantly less than that in control group ( <0.05), the number of dressing have significantly shortened compared with control group ( <0.01), and the dressing change interval in control group had significantly difference ( <0.01) . The effect of 2 patients in control group after skin flap to repair was poorer, but the observation group did not appear significant necrosis. Compared the good rate of two groups, the observation group patients was significantly higher than control group ( <0.01) . The therapy good rate of observation group was significantly better than that of control group (<0.01) . Conclusion The negative pressure closed drainage based ascending latissimus dorsi bridge free skin flap repairment has contributed to cure the refractory wound recovery significantly.

Objective: To verify that COX-2 promoter can drive its downstream genes specifically in COX-2-positive o-varian cancer cells; Moreover, comparing with CMV promoter, analyze the transcript efficiency of COX-2 promoter. Methods: Contacting the recombinant plasmids named COX-2-BAX and CMV-Luc. After transient transfection liposome-mediated with the plasmids COX-2-Luc and CMV-Luc, respectively, the expression of Luciferase reporter gene was measured in COX-2-positive ovarian cancer cell line-SKOV3 and COX-2-negative colon cancer cell line-SW480. SKOV-3 and SW480 were transfected with COX-2-BAX and CMV-BAX in the same way, respectively. The apoptosis rates were measured through flow cytometry. Results: The recombinant plasmids named COX-2-BAX and CMV-Luc were constructed successfully. The expression efficiency of reporter gene was 1554 ? 86. 5 in SKOV3 and 53. 7 ? 10.9 in SW480 after 24 hours transfected with phPES2, 9851. 7 ? 129. 5 in SKOV3 and 8831. 0 ? 167. 3 in SW480 after 24 hours transfected with CMV-Luc in the same way. The apoptosis rate was 10.4% in SKOV3 and 3.7% in SW480 after transfected with COX-2-BAX, 21.7%in SKOV3 and 25. 6% in SW480 after 36 hours transfected with pcDNA3-BAX in the same way. Conclusions: COX-2 promoter can drive its downstream genes specifically in COX-2-positive ovarian cancer cell lines, but its expression efficiency wasmarkedly lower than CMV promoters. With proper modification, COX-2 promoter is expected to be useful in gene therapy of ovarian cancers.
