RESULTS The hospital infection rate was 4.6-6.42% in these years.Risk factors and the abuse of antibiotic were decreasing. CONCLUSIONS In order to control hospital infection rate,mensures should be taken including intensively monitoring the departments with high infection rate,strengthening hospital operation,rationally using the antibiotics,and studying the management for hospital infection.

Objective:To investigate the strategies and methods of pancreatic cancer immunotherapy adopt cytotoxic T lymphocytes activated by dendritic cells(DCs),which modified by heat shock protein 70 peptide complex(HSP70-PC).Methods:HSP70 peptide complex from lumps of tumor-bearing mouse innoculated with pancreas cancer cell(MPC83)were purified by ConA-Sepharose and ADP-Agarose affinity chromatography.Dendritic cells derived from normal murine bone marrow were induced by GM-CSF and IL-4.MTT method was applied to analyses the proliferation activities of DCs.To achieve the specific T lymphocyte cells,DCs modified with HSP70 peptide complex were coculture with murine spleen lymphocytes for 48 hours.Then these activated lymphocytes were cocultured with MPC83 at ratio of effect-target 10∶1 and 20∶1 in vitro and the killing activities were detected by MTT method.Results:High purify HSP70-PC was obtained;104 DCs need 50～100ng of HSP70-PC to modify,100?g of HSP70-PC peptide complex can be extracted from per 1g lump;T cells stimulated by HSP70-PC modify DCs showed more specific cytotoxic activity to MPC83 than lymphocytes activated by DCs without HSP70-PC in vitro.Conclusion:We can extract high purity HSP70-PC for clinical individual immunotherapy from pancreatic cancer lump by using hypobaric affinity chromatography;DCs vaccine modified with HSP70-PC has significant kill effect against pancreatic cancer cell in vitro.

Objective: To investigate the prevalence of frailty and its influencing factors among the elderly, so as to provide the evidence for prevention and control of frailty. Methods: The elderly population at ages of 65 years and older were selected from 14 administrative villages or communities in Wuzhong District, Suzhou City, Jiangsu Province, using the random cluster sample method from July to November, 2022. Demographic information, smoking and alcohol consumption were collected through questionnaire surveys. Physical activity, sleep quality and frailty were evaluated using the International Physical Activity Questionnaire-Short, Pittsburgh Sleep Quality Index and the FRAIL Scale, respectively. Factors affecting frailty among the elderly were evaluated using a multinomial logistic regression model. Results: A total of 8 782 elderly peolple were surveyed, including 4 259 males (48.50%) and 4 523 females (51.50%). The median age was 71.00 (interquartile range, 8.00) years. There were 2 145 cases with pre-frailty (24.42%) and 189 cases with frailty (2.15%). Multinomial logistic regression analysis showed that age (75-<85 years, OR=1.330, 95%CI: 1.186-1.492; ≥85 years, OR=2.452, 95%CI: 1.882-3.195), smoking (current smoking, OR=0.838, 95%CI: 0.714-0.983), physical activity level (low, OR=1.161, 95%CI: 1.010-1.333) and sleep quality (poor, OR=2.248, 95%CI: 1.822-2.774) were associated with pre-frailty; age (75-<85 years,OR=2.629, 95%CI: 1.921-3.596; ≥85 years, OR=3.067, 95%CI: 1.621-5.801), educational level (junior high school and above, OR=0.488, 95%CI: 0.298-0.798), body mass index (underweight, OR=1.848, 95%CI: 1.023-3.337; obesity, OR=1.798, 95%CI: 1.180-2.740), smoking (quit smoking, OR=1.787, 95%CI: 1.007-3.171; current smoking, OR=0.448, 95%CI: 0.242-0.830), alcohol consumption (yes, OR=0.532, 95%CI: 0.291-0.972), physical activity level (low, OR=2.757, 95%CI: 1.646-4.616) and sleep quality (poor, OR=3.911, 95%CI: 2.438-6.273) were associated with frailty. Conclusion Older, low physical activity level, poor sleep quality, underweight and obesity are associated with frailty of the elderly.

Vascular dementia (VaD) is the second common subtype of dementia after Alzheimer's disease. However, there is still a lack of medication that demonstrates clinically relevant symptomatic improvement. Static blood obstructing the brain is the main Chinese medicine syndrome of VaD.

The aim of this study is to prepare self-microemulsifying drug delivery system (SMEDDS) of the mixture of paeonol (Pae) and borneol (Bor). Solubility test, ternary phase diagrams and simplex lattice method were employed to screen and optimize the formulation of the mixture of Pae and Bor-loaded SMEDDS. After formed into microemulsions, the particle diameter (PD) was determined and a TEM was employed to observe the microemulsions' morphology. The contents of Pae and Bor were determined by gas chromatography. As a result, while ethyl oleate (EO) as the oil phase, cremophor EL35 (EL35) as surfactant and Transcutol HP (HP) as cosurfactant, the range of the microemulsion on the ternary phase diagram was larger than other combinations. And at a ratio of 20:45:35, the microemulsions' PD was about 34 nm and the polydispersity index (PI) was about 0.2. There were 16% of Pae, 2% of Bor, 16% of EO, 37% of EL35 and 29% of HP in the prepared SMEDDS. The preparation process of the Pae and Bor-loaded SMEDDS based on Xingbi Fang is simple and feasible. This study provides a reference for the researches on the related traditional Chinese medicine and the related components.

Objective The clinical effect of the lateral femoral cutaneous artery flap for soft tissue defects of leg wounds. Methods From October 2007 to January 2016, VSD was firstly used to promote the growth of granulation tissue. When the growth of granulation tissue became satisfactory, flaps were designed based on the anatomical characteristics of the lateral femoral cutaneous artery. We repaired 20 cases of wound defects by cutting flaps that coincide with the recipient vessels. Result 20 cases were followed up for 6 to 24 months, 12 months on average. All flaps were survived and only one case had small area of necrosis flap which was healed by replacing medicines. In all cases, wounds were healed and flaps showed good color and good texture. The strength of quadriceps muscle was good and the extension of knee flexion was 0° to 150°. Conclusion To The lateral femoral cutaneous artery flap is used for soft tissue defects of refractory wounds on leg , flap donor sites are sutured directly, the treatment period is shorten and the method is safe and effective. The lateral femoral cutaneous artery flap is one of ideal choices for wound tissue defects.
