Objective To investigate the curative effect of different biofeedback and electrical stimulation solutions on female stress urinary inconti-nence(SUI). Methods A total of 40 female patients with mild-to-moderate SUI were randomly divided into two groups(n=20 each group)and treated by the biofeedback and electrical stimulation. In the treatment group,the current increased in the middle of the treatment on the basis of the initial threshold of stimulus intensity to make a new tolerable threshold of stimulus intensity. In the control group,the patients were treated with the initial threshold of stimulus intensity during the whole treatment. The curative effects in these two groups were determined by the comprehensive strength of pelvic floor,the 1 h urine pad test results,and the life quality scores of urinary incontinence. Results After treatment,there were signifi-cant improvements in all the above indicators in two groups(P<0.05),and the results is better in the treatment group than in the control group. The effective rate in treatment group(95%,19/20)was higher than that in the control group(65%,13/20)(P<0.05). Conclusion The biofeedback and electrical stimulation were effective and safe in the treatment of women with SUI. The curative effect of patients treated with increasing current in the middle of the treatment is better,suggesting that it can be widely applied in clinic.

Objects: To measure practicing medical students' basal energy expenditure(BEE). Methods: 200 practising medical students were chosen to measure BEE by standard method of CCM metabolism cart,and the BEE results were compared with forecast values from the calculation formula of healthy adult. Results: Actual BEE of male students was(4 920.4?1 343.1)kJ/d,female(3 393.2?824.2)kJ/d.The results were significantly lower than corresponding forecast values.Conclusion: The BEE of practising medical students is lower than forecast values from the calculation formula of healthy adult,showing that students' constitution was poorer.The possible reasons may be less exercise and diet.

Objective: To investigate nutrition status and diet condition of 1 000 medical studients,and intervent their diet in order to improve the constitution.Methods: 200 practicing medical students' basal energy expenditure was firstly measured and their diet structure was investigated 1 000 practicing medical students were choosed and their diet kinds and calories were recommended to reach the standard quantity.After one year,their nutrition status and diet structure were remeasured.Results: Under the nutrition doctor' direction,they could change unreasonable diet structure,and received a balanced and enough diet.At last,their nutrition status had been improved.Conclusion: It is feasible to adjust the medical students' diet structure and improve their nutrition and health status by the means of nutrition education.

OBJECTIVE:To develop a HPLC method for determination of the content of baicalin in Kugan gran?ules.METHODS:ODS-C 18 column was used and methanol-water-acetic acid(45∶55∶1)was used as mobile phase and UV detection wavelength was274nm.RESULTS:There was a good linear relationship between the concentration of Baicalin and absorption area value in range of0.25?g～2.5?g r=0.9992.The average recovery was98.4%with RSD=1.09%(n=5). CONCLUSION:The method was highly repeatable and accurate.

Objective To develop a sandwich enzyme-linked immunosorbent assay ( ELISA) for the determination of a humanized antibody MIL50.Methods RiVax, a mutant of RTA (a chain of ricin) expressed in E.coli, was used as the coating protein.Horseradish peroxidase (HRP) labeled IgG of goats against humans was used to determine MIL 50 captured by RiVax coated on the plate.Results Compared with ricin, RiVax could bind well with MIL50,indicating it could be used as a coating protein to determine MIL50 instead of holotoxin.Using this method, the detective limit of MIL50 in PBST (PBS containing 0.1%Tween 20) could be as low as 0.030 mg/L.The absorbance value of ELISA for MIL50 in the ser-um and homogenate of the liver , spleen, lung, kidney, muscle of rats was lower than that in PBST .Conclusion The sandwich ELISA is a sensitive method for the analysis of distribution of MIL 50 in rat tissues.

Objective To explore the best time period of pulse oximetry in congenital heart disease (CHD) screening. Methods Totally 5433 newborns delivered or treated in Ningbo Women and Children’s hospital were enrolled in the study. Cardiac color ultrasound was used to arrive diagnosis and every screening time period (0?~?24 h、24 h?~?48 h、48 h?~?72 h) was analysed. Results Among the three time periods: the sensibility was in the range of 54.72%?~?67.92%, specificity was 99.11%?~?99.61%, false negative rate was 32.08%?~?43.40%, false positive rate was 0.39%?~?0.89%, Youden index was 0.54?~?0.68, coincidence rate was 98.67?~?99.30, and kappa was 0.44?~?0.65. Conclusion The best screening time is the period between 48h and 72 h after birth.

Objective To explore the expression of COX-2 and p38MAPK in patients with trauma MODS. Methods Forty MODS patients were evaluated. The levels of peripheral blood mononuclear cells COX-2 and p38MAPK in MODS patients and 40 normal controls was detected by enzyme linked immunosor-bent assay (ELISA). RT-PCR was used to measure the COX-2 mRNA and p38MAPK mRNA expression of in PBMCs. ANOV and correlation analysis were used in statistical analysis. Results The levels of COX-2 and p38MAPK of PBMCs and the mRNA expression in MODS group were higher than in control group (all P <0.05). The levels of COX-2 and p38MAPK of PBMCs and the mRNA expression in dead group were higher than in survival group( all P <0.05). The levels of COX-2 and p38MAPK of PBMCs were positively correlated, (r =0.6 147, P<0.01). The expression of COX-2 mRNA, p38MAPK mRNA of PBMCs and APACHE I scoring were positively correlated (r1 =0.5 009, P1 <0.05,r2 =0. 5 316, P2 <0. 05). Conclusions COX-2 and p38MAPK of PBMCs take part in the onset of MODS, and may service as index to judge the prognosis of MODS.

ObjectiveTo investigate the ratios of peripheral blood CD4+CD25highFoxp3+ regulatory T cells of systemic lupus erythematosus(SLE) patients,and explore its association with disease activity and nephropathy.MethodsPBMC lymphocytes in 42 patients with SLE and PBMC in 40 normal healthy donors were evaluated for the proportion of Treg cells,as a percentage of the total CD4+ cells,by flow cytometric analysis.Levels of mRNA for Foxp3 were measured with a real-time quantitative PCR.The proportion of Treg cells and its association with SLEDAI,nephropathy,serum anti-dsDNA antibody,and C3 levels were analyzed.Statistical analysis was conducted with t-test and Spearman's correlation analysis.ResultsPatients with active disease had statistically significantly lower levels of CD4+CD25highFoxp3+ Treg than normal controls [(4±3)％ vs (7±4)％,P＜0.05],while no significant difference could be found between patients with nonactive disease and normal controls(P＞0.05).The percentage of peripheral blood CD4+CD25highFoxp3+ Treg/CD4+ in patients with active disease was significantly lower when compared to patients with non-active disease [(9±6)％ vs (10±6)％,P＜0.05],and it was related to the disease activity.SLE patients with nephropathy had significantly lower levels of CD4+CD25highFoxp3+ Treg and CD4+CD25highFoxp3+ Treg/CD4+ than patients without nephropathy(P＜0.05).Foxp3 mRNA levels were lower in PBMC from active disease patients than those in non-active disease.In addition,there was a negative correlation between the populations of CD4+CD25highFoxp3+ and SLEDAI(r=-0.5892,P＜0.05).There was a negative correlation between the percentage of CD4+CD25highFoxp3+/CD4+ and SLEDAI (r=-0.4962,P＜0.05),while there was a positive correlation between the percentage of CD4+CD25highFoxp3+/CD4+ and C3(r=0.3867,P＜0.05).There was a positive correlation between the populations of CD4+CD25highFoxp3+ and Foxp3 mRNA(r=0.6142,P＜0.01 ).ConclusionThese suggest that the decrease of CD4+CD25highFoxp3+ Treg and Foxp3 mRNA expression may play a crucial role in the pathogenesis of SLE.
