Objective To study the primiparas' sexual problems after delivery and the effect of in-dividualized nursing interventions on improvement of these problems in order to provide theoretic base-ment for sexual health education after delivery. Methods 248 primiparas after delivery in women's hos-pital were randomly divided into the intervention group and the control group with 124 cases in each group. All of them received self- designed questionnaires about sexual problems one year before pregnancy. The primiparas in two groups all receives routine care. Besides, the intervention group was given sexual health manual and received one-to-one individualized nursing intervention on sexual life after delivery according to their own conditions. The two groups were all received countercheck during 4 to 6 months after delivery and the results underwent X2 test. Results There was no significant difference between the sexual prob-lems one year before pregnancy for the two groups. But when calling back during 4 to 6 months after deliv-ery, compared with the control group, the intervention group had less sexual problems. Conclusions It is necessary to strengthen sexual health education in order to improve the sexual problems after delivery. Indi-vidualized nursing interventions can not only fulfill the sexual health demands of different primiparas after delivery, but also guarantee the women's privacy and safety.

METHODS 27 cases of superficial parotidectomy with preservation of the Steven’s duct were reviewed retrospectively. Complications and treatment outcomes were analyzed. RESULTS Almost all cases investigated resulted in satisfactory outcomes. CONCLUSION Superficial parotidectomy with preservation of the Steven’s duct is a possible alternative for some patients, especially those with benign parotid tumour.

We investigated health condition and evaluate the viability of Barthel's measuring scale for 1297 elder patients at 17 nursing homes.We nursed all patients by standards and performed a comparison study.The nursing percentages of highest and lowest levels were higher than the previous ones ( P ＜ 0.01 ),while the nursing percentage of normal level was lower than the previous one ( P ＜ 0.01 ).The cooperation between doctors and nurses became optimized through progressive patient care.Ideal nursing standard should be based upon the doctors' judgment and nurses' evaluation.The new standard will be more suitable for patients and easier to control for nurses.

Objective To analyze the changes of celluar and humoral immunity in children with juvenile idiopathic arthritis(JIA),as well as the changes in different subtypes,and to investigate the role of cellular and humoral immunity in the pathogenesis of JIA.Methods Ninety-two JIA subjects and 82 controls(healthy children) were included into this study.The levels of T lymphocyte subsets,natural killer (NK)cells,and B cells were analyzed by using flow cytometry.The serum interleukin-1 (IL-1),tumor necrosis factor-α (TNF-α),interleukin-l0 (IL-10),transforming growth factor-β(TGF-β) levels were detected by using enzyme-linked imnmunosorbent assay (ELISA).The serum IgG,IgM,IgA and C3,C4 levels were detected by using velocity scatter turbidimetry.Independent t-test,One-Way ANOVA test and Pearson analysis were adopted for data analysis.Results 1.In the group of JIA,the levels of CD3,CD4,IL-1,TNF-α,IgG,IgM,IgA and C3 were higher than those in the control group(all P ＜ 0.05),while the levels of CD4CD25,CD8,NK cells,IL-10 and TGF-β were lower than those in the control group(all P ＜0.05),and the ratio of CD4/CD8 was higher than that in the control group (P ＜ 0.05).2.In the group of systemic-onset JIA (so-JIA),the levels of CD4,IL-1,TGF-β,IgG,IgM,IgA,C3 and the ratio of CD4/CD8 were higher than those in the oligoarthritis JIA group(all P ＜ 0.05),while the levels of CD4CD25,CD8,IL-10 were lower than those in the oligoarthritis JIA group(all P ＜ 0.05).In the group of polyarthritis JIA,the levels of IL-1,TNF-α,IgG,IgM and IgA were higher than those in the oligoarthritis JIA group(all P ＜0.05),while the levels of CD4CD25,CD8,IL-10 were lower than those in the oligoarthritis JIA group (all P ＜ 0.05) ; In the group of so-JIA,the levels of CD4,TGF-β,C3 and C4 were higher than those in the polyarthritis JIA group (all P ＜ 0.05).3.The value of IL-1,TNF-α were positively correlated with that of C-reactive protein (CRP),erythrocyte sedimentation rate(ESR) in the JIA group(all P ＜ 0.05),while the value of IL-10,TGF-β was negatively correlated with that of CRP,ESR(all P ＜ 0.05).Conclusions There are cellular immunity and humoral immunity disorders in the JIA.Cellular immunity and humoral immunity are all involved in the pathogenesis of JIA.T helper cells are activated and Th1 cytokines increase,suppressive T cells,regulatory T cells impairment and suppressive cytokines decrease but immunoglobin increase,which involve in auto inflammation reaction and articular destruction in JIA.The immunity disturbances are more striking in so-JIA and polyarthritis JIA.IL-1,TNF-α,IL-10 and TGF-β are correlated with the disease activity.

OBJECTIVE To select the superior one from two skin-cleaning disinfection methods so as to reduce the possibility of hospital infection.METHODS The water plus soaps(control group) and Daniel disinfectants(test group) were used separately to clean and disinfect the skin of patients in intensive care unit(ICU).The degree of skin-cleaning of patients and hand pollution of nurses were observed and analyzed.RESULTS The number of bacteria on the skin of patients of the test group was remarkably lower than that of the control group with a statistically significant difference(t=7.94,P

AIM To investigate the pharmacokinetic behaviors of total flavonoids from Epimedii Folium in osteoporotic rats in vivo.METHODS Twelve rats were divided into model group and sham group,after which the osteoporotic rat model was established by removing bilateral ovaries.After intragastric administration with total flavonoids (500 mg/kg),HPLC-DAD was applied to detecting the plasma concentrations of total flavonoids' prototype glycosides (epimedin A,epimedin B,epimedin C,icariin) and their metabolites (sagittatoside A,sagittatoside B,2-O-rhamnosylicariside Ⅱ,baohuoside Ⅰ,icaritin) at thirteen time points (0.083,0.25,0.5,0.75,1,2,3,4,6,8,12,24 and 48 h),then the plasma concentration-time curves were drawn,followed by the calculation of pharmacokinetic parameters.RESULTS Doubled peaks were observed in the plasma concentration-time curves of total flavonoids' prototype glycosides and their metabolites in both groups.Compared with the sham group,the integrated AUC and Cmax in the model group were significantly decreased (P ＜ 0.01),as well as the prolonged t1/2 (P ＜ 0.01).CONCLUSION The in vivo absorption and metabolism of total flavonoids from Epimedii Folium are much slower in the state of osteoporosis,thus affects the efficacy.

Objective To investigate the expression and significance of microRNA - 21(miR - 21)in acute kidney injury mice model at the different time points following ischemic/ reperfusion. Methods C57BL/ 6J mice were divided into 3 major groups:the control group(C group),sham operation group(S group)and ischemia - reperfusion group(IR group). Later 2 groups were divided into 9 sub - groups respectively according to the time following reperfu-sion. Automatic biochemical analyzer detected serum creatinine(Scr),blood urea nitrogen(BUN)level. HE staining detected renal pathological damage. Renal tubulointerstitial pathological score accessed pathological damage. Real time - PCR tested the expression of miR - 21 and mitogen - activated protein kinase kinase 3(MKK3)mRNA in renal respectively. Immunohistochemistry staining tested expression of MKK3. Results IR group's Scr,BUN levels gradually increased following reperfusion,24 h reached its peak,then gradually declined. The Scr,BUN level had statistically sig-nificant difference between IR group and S group at the same time subgroup from 3 h to 168 h following reperfusion(all P ﹤ 0. 01). The change of kidney damage and pathological changes of interstitial and tubular injury score consensus with renal function. miR - 21 increased gradually in renal ischemia after reperfusion,24 h peaked and then stabilized at this high level. miR - 21 was positively correlated with pathological tubulointerstitial injury from 0 h to 168 h after reperfu-sion(r = 0. 969,P ﹤ 0. 05). IR group's MKK3 mRNA and protein expression rose sharply following ischemia/ reperfu-sion,24 h peaked,and then gradually decreased. From 3 h to 168 h,the expression of MKK3 mRNA and proteins had significant difference at each same time points subgroups between IR group and S group(all P ﹤ 0. 01). Conclusions miR - 21 increases gradually in renal ischemia after reperfusion,24 h peaked and then stabilized at this high level. miR - 21 is positively correlated with pathological tubulointerstitial injury,which may be associated with the negative regulated relationship between miR - 21 and MKK3.

Objective To investigate the molecular epidemiological characteristics of Staphylococcus aureus associated with bloodstream infection in hospital. Methods 47 Staphylococcus aureus strains isolated from bloodstream in PLA General Hospital were collected from January 2006 to December 2008. Susceptibility of the strains to 11 antimicrobial agents was detected and DNA homology of them was analyzed with Rep-based DiversiLab~(TM) Microbial Typing System. Panton-Valentine leukocidin (PVL)gene was determined by PCR. For methicillin-resistant Staphylococcus aureus (MRSA) strains,the genotypes of SCCmec were determined and ST239 clone was screened with multiplex PCR. Multilocus sequence typing (MLST) was used to determine the STs of the selected isolates. Results In the 47 Staphylococcus aureus isolated from blood,methicillin-resistant strains accounted for 51.1%,all belonged to SCCmec Ⅲ type,with only 2 pvl gene positive strains identified. 12 different patterns (A-L) were found among 47 strains with Rep-PCR. All MRSA strains clustered in the A and B subtypes. Conclusion Most MRSA strains isolated from blood in PLA General Hospital belonged to ST239-MRSA-SCCmec Ⅲ clone. DiversiLab~(TM) Microbial Typing System could provide a rapid and effective method to investigate the molecular epidemiological characteristics of Staphylococcus aureus in the hospital settings.
