Objective To explore the relevance of the microRNA-192 (miR-192) levels and prognosis in patients with diabetic nephropathy (DN).Methods A total of 59 cases with duration of type 2 diabetes mellitus (T2DM) ≥10 years from January 2010 to July 2011 were retrospectively admitted.The miR-192 levels were determined after admission,and other relevant clinical data were collected.And the patients were followed-up for 24 months.According to the patient's prognosis,the patients were divided into DN group(20 cases) and non-DN group(39 cases),and the relevant information was analyzed in two groups.Results The miR-192 levels in DN group were lower than those in non-DN group[(4.47 ± 2.27) μ g/L vs.(7.28 ± 2.39) μ g/L],and there was significant difference (P ＜ 0.05).Multivariate Logistic regression analysis showed that hypertension history,smoking history,high glycosylated hemoglobin,low fasting C-peptide,low 24 h urine protein,low miR-192 level,high body mass index was the independent risk factors of prognosis of T2DM (P ＜ 0.05).The area under the receiver operating characteristic (ROC) curve was 0.697 in miR-192 levels individual predicting progression to DN stage,0.823 in six others without miR-192.After joining seven indicators forecast area under the curve increased significantly(0.856,95％ CI:0.832-0.904).The miR-192 levels 5.14 μ g/L was the best predictive value to the critical value of community,and the patients were divided into miR-192 ＜ 5.14 μ g/L group (28 cases) and miR-192 ≥ 5.14 μ g/L group (31 cases).The number of progression to DN within 24 months in miR-192 ＜ 5.14 μg/L group was more than that in miR-192 ≥5.14 μ g/L group (16/28 vs.4/31,P ＜ 0.05).Conclusions A reduced level of miR-192 is an independent risk factor that can lead to poor prognosis in patients with DN,and can predict adverse outcomes in patients with T2DM effectively.

Objective To establish the preparation method of Xiao' er Jiere hollow type suppository and determination method of the dissolubility.Methods Xiao' er Jiere hollow type suppository and ordinary suppository were prepared.With bacalin and chlorogenic acid as the standards,the in-vitro dissolution test and HPLC method were applied to determine the accumulated dissolution rate of bacalin and chlorogenic acid in two different types of suppository.Results The linearity of bacalin was in the range of 0.040 ? g～ 0.320 ? g(r=0.999 7)and that of chlorogenic acid was in the range of 0.064～ 0.512 ? g(r=0.999 8).The accumulated dissolution rate of the hollow type suppository was over 97 % in 30min.Conclusion Drug release rate of hollow type suppository is higher than the ordinary suppository.The method is stable and accurate.

Objective To investigate the influence of super fine crushing technique on dissolution rate of Sunshang Capsule (SC). Methods With the dissolution of active components and notoginsengside as the markers, the dissolution rate in Sunshang Capsule and Sunshang powder which were prepared by super fine crushing method and fine crushing method respectively was compared by TLC and HPLC. Results The stain of Sunshang Capsule was bigger and darker than that of Sunshang Powder, time-limited dissolution of SC was 4.66 %higher and the content of notoginsengside R1 was 6 %higher than those of Sunshang Powder. Conclusion Super fine crushing technique can increase the dissolution rate of SC and this will supply evidence for the process of SC preparation.

In this paper, according to the requirement of the focused sound field measurement, a focused sound field measurement system was established based on the LabVIEW virtual instrument platform. The system can automatically search the focus position of the sound field, and adjust the scanning path according to the size of the focal region. Three-dimensional sound field scanning time reduced from 888 hours in uniform step to 9.25 hours in variable step. The efficiency of the focused sound field measurement was improved. There is a certain deviation between measurement results and theoretical calculation results. Focal plane--6 dB width difference rate was 3.691%, the beam axis--6 dB length differences rate was 12.937%.

The supramolecular inclusion properties of beta-cyclodextrin (beta-CD) and resveratrol (Res) were investigated using drug-protein interaction spectroscopy method. The differences between the results of interaction spectroscopy method and the results of classical method were compared. The total energy of the stable inclusion of cyclodextrin-resveratrol was calculated by Gaussian theory calculation. The stable inclusions in the process of interaction between resveratrol/inclusion complex and bovine lactgoferrin (BLF) were studied by molecular modeling. The results showed that the interaction spectroscopy method could explain the property of the inclusion in a more sensitive manner, it also interpreted the conveying mechanism of BLF binding with inclusion complex. The molecular modeling result showed consistent results with Gaussian theory calculation; both of the two methods obtained the stable configuration of beta-CD-Res inclusion. The relevant result provided an experimental consequence for the pharmacology research of beta-cyclodextrin-resveratrol inclusion complex as well as offering a new reference to the future research of supramolecular inclusion compound.

The dynamic changes of the T cell subsets in the peripheral blood and the serum level of immunoglobin and complement C3 were observed in 32 breast cancer patients before and after surgery and after radiotherapy.20 patients with benign breast diseases and 20 normal women were observed likewise.It was found that the Ts cells and serum IgG and IgA were significantly increased and the TH/Ts ratio markedly decreased in the breast cancer group as compared with those of other 2 groups.In the first postoperative week,TH cells and TH/TS ratio were markedly decreased in all cases operated on.One month after operation,all the parameters returned nearly to the normal level in the group with benign breast diseases.In the group without radiotherapy,the proportion of OKT3+ cells in the 3rd postoperative month and OKT4+ cells in the 6th postoperative month exceeded the preoperative level while that of OKT8+ cells decreased.In the first week after radiotherapy,TH cells decreased,Ts cells increased and TH/Ts ratio decreased significantly.Meanwhile serum IgG was elevated.OKT3+ cells markedly increased in the 6th month after radiotherapy and OKT8+ cells decreased 1 year after that.The immunore-active state of breast cancer patients and the effects of therapeutic measures on them were discussed.

CONCLU-SIONS:Foreign aid relief teams can foresee the quantity and type of rescue drugs depending on station sanitary conditions,medica-tion habits,the characteristics of patients to guarantee the medical detachment work and avoid medical resources waste.

OBJECTIVE To survey the varieties of microorganism on nurse hands and probe into its controlling measure in general hospital.METHODS We sampled microorganism of nurse hands during intravenous fluids infusion in the Respiratory Department,the Cardiovascular Department,the Department of Digestion,Gynecology and Obstetrics Department,the Department of Thoracic Surgery and the Department of Organ Transplantation in our hospital.All samples carried out co-cultures of fungi and bacteria.RESULTS The varieties of microorganism included not only opportunistic pathogens such as Acinetobacter,Corynebacterium,Pantoea agglomerans(Enterobacter agglomerans) former,and Escherichia coli,but also strong pathogenic microorganisms such as Staphylococcus aureus,and it is so common that finding meticillin-resistant coagulase-negative staphylococci.CONCLUSIONS Nursing staff's hands contamination is serious in the process of manipulating operation in general hospital,emphasis should be placed on prophylaxis and control for nosocomial infection.

Objective: To study the protective effect of Chinese materia medica of tonifying kindey and eliminating sputum on chronic bronchitis mice induced by tobacco smoking from aspect of pathomorphology changes. Methods: 60 Healthy male mice were divided into normal group, chronic bronchitism model group, Guilong Kechuanning group, high and low dosage of tonifying kindey and eliminating sputum groups at random, each 12. Model mice of chronic bronchitis were induced tobacco smoking, giving Guilong Kechuanning and Chinese materia medica of tonifying kindey and eliminating sputum at the same time. The pathomorphology changes of trache and lung tissue were observed under light microscope. Results: Compared model group, the pathomorphology changes of trache and lung tissue in Guilong Kechuanning group, high and low dosage of tonifying kindey and eliminating sputum groups relieved(P
