Objective:Taking Chongyang county of Hubei Province as an example, the paper describes the in-tegration of the maternal and child health ( MCH) and family planning ( FP) service system and analyses the key ele-ments to provide reference for promoting integration. Methods: qualitative interviews and quantitative questionnaire were used to collect data. The software QSR Nvivo 8. 0 and SPSS 17. 0 were used for qualitative and quantitative data analysis. Results:Based on the correct understanding of integration, Chongyang implements the supporting policies actively, maintains the original compensation mode unchanged, follows the principle of“no reducing headcounts and no downsizing” strictly, promotes the merger of institutions rapidly, adjusts the service contents and methods reasona-bly, and integrates the maternal and child and family planning information platform. Conclusion:The correct concept of integration, appropriate staffing, and stable funding in Chongyang provide rich experiences for future research. However, there is room for improvement in staffing, incentive mechanisms, service content, and forms.

Ethanol can be produced from lignocellulose by first hydrolysing the material to sugars,including hexose,and pentose,and then fermenting the hydrolysate to ethanol.Hydrolysis using dilute-acid has advantages over other methods.However,compounds which inhibit fermentation are generated during this kind of hydrolysis.Therefore,it is important to focus on microorganisms metabolizing xylose and tolerating/decomposing inhibitors,on detoxification methods of hydroly- sates with low-cost and facilitated to scale-up,and different fermentation modes in ethanol production from hydrolysate.This review summarized the advance in above aspects.

OBJECTIVETo observe the effect of magnesium sulfate, Nifedipine Tablet (NT) combined Salvia Injection (SI) on endothelin-1 (ET-1), nitric oxide (NO), thromboxane A2(TXA2), prostacyclin I2(PG2), and hemorheology of preeclampsia patients.

METHODSTotally 704 preeclampsia patients were randomly assigned to the treatment group and the control group, 352 cases in each group. All patients were treated with magnesium sulfate combined NT (on the first day: slow intravenous injection of magnesium sulfate 5 g + intravenous dripping of magnesium sulfate injection 10 g + oral administration of NT 30 mg; on the second and third day, intravenous dripping of magnesium sulfate injection 10 g + oral administration of NT 30 mg), while those in the treatment group were dripped with SI additionally at 20 mL per day for 3 consecutive days. Before and after treatment plasma levels of endothelin-1 (ET-1), nitric oxide (NO), TXA2, PGi2, and hemorheology indicators [such as high blood viscosity (HBV), low blood viscosity (LBV), plasma viscosity (PV), erythrocyte rigidity index (ERI), fibrinogen (FIB)] of two groups were detected.

RESULTSCompared with the same group before treatment, serum levels of ET-1, TXA2, HBV, LBV, PV, ERI, and FIB decreased in the two groups after treatment (P <0. 05), but levels of NO and PG2 increased (P <0. 05). Compared with the control group in the same period, levels of ET-1, TXA2, HBV, LBV, PV, ERI, and FIB decreased in the treatment group after treatment (P <0. 05), but levels of NO and PGI2 increased (P <0. 05).

CONCLUSIONMagnesium sulfate, NT combined SI could effectively regulate the balance of ET-1/NO and TXA2/PGI2, and improve hemorheology of preeclampsia patients.

OBJECTIVETo explore factors affecting occupational adaptability in nurses for offering basis to increase their occupational adaptability.

METHODSFive hundred and forty-five nurses were investigated with work ability index questionnaire and occupational stress instruments.

RESULTSThere were many risk factors affecting occupational adaptability in nurses. The main variables that influenced occupational adaptability included work-overtime, mental load, social support, physical environment, and job hazards. The social support was the factor increasing the occupational adaptability of the nurses (P < 0.01, OR = 0.912). Five factors including work overtime, mental load, social support, physical environment and job hazards were introduced in the Logistic equation. The established functions were: Logit (P) = -11.357 + 1.011x(1) + 0.335x(2) - 0.076x(3) + 0.260x(4) + 0.129x(5).

CONCLUSIONThere are many risk factors affecting occupational adaptability in nurses. Relevant measures should be taken to promote the occupational adaptability in nurses to reduce the risk factors.

OBJECTIVE To analyze the preliminary regulation between the skin cell toxicity of EOs and drug property char-acteristics of Chinese materia medica(CMM)on the same platform.METHODS The physicochemical parameters of 33 kinds of EOs were measured.MTT assays were applied to evaluate the cell toxicity of EOs on human HaCaT keratinocytes.Finally, data mining technique was applied to analyse experimental data for the purpose to illustrate the relationship between skin cell toxicity of EOs and drug properties of CMMs.RESULTS By non-linear canonical correlation analysis,high correlation(P=0. 041 1<0.05)was found between skin cell toxicity of EOs and channel tropism property of CMMs.EOs with the properties of liver,lung,stomach,kidney and large intestine channel possess lower skin cell toxicity.However,EOs with the properties of heart,pericardium,spleen,bladder,san-jiao and gall bladder channel possess higher skin cell toxicity.A mathematical model between drug property including four mature,five flavor,channel tropism of CMMs and skin cell toxicity of EOs was estab-lished based on non-linear canonical correlation analysis.In the model,significant correlation was found(P=0.041 4<0.05). EOs from CMMs with the properties of cool nature,bitter flavor plus liver or lung or kidney or large intestine channel might be superior in safety towards the skin cells.On contrary,EOs from CMMs with the properties of hot nature,sweet flavor plus heart or pericardium or spleen or bladder or san-jiao or gall bladder channel might be superior in toxicity towards the skin cells. CONCLUSION The skin cell toxicity of EOs is affected by drug property characteristics of CMMs,especially channel tropism property.

This study is to investigate the mechanism of human promyelocytic leukemia HL-60 cells proliferation induced by alteronol in vitro. Human promyelocytic leukemia HL-60 cells cultured in vitro were treated with different concentrations of alteronol. Inhibition rate was detected by SRB assay. Cellular morphological changes were observed by Hoechst and AO/EB (acridine orange/ethidium bromide dye) staining. The apoptosis rate was determined by Annexin V-FITC/PI assay. Cell cycle distribution was determined by flow cytometry. Western blotting analysis was carried out to determine the cell cycle related proteins. The proliferation of HL-60 cells treated with alteronol was inhibited in a concentration-dependent manner. Based on cell viability assay, observation on cell morphology and apoptosis rate, it confirmed that alteronol played an obvious role in proliferation inhibition of human promyelocytic leukemia HL-60 cells, but it did not induce apoptosis in human promyelocytic leukemia HL-60 cells in different concentrations groups. Alteronol could effectively inhibit the proliferation of human promyelocytic leukemia HL-60 cells inducing cell cycle arrest at G1 phase, as well as, alteration expression of cell cycle proteins level of CyclinD1 and pRb.

OBJECTIVETo detect sperm plasma membrane integrity (PMI) of cigarette smoking infertile males using SYBR-14/ PI fluorescent staining and flow cytometry and investigate its clinical significance.

METHODSWe collected semen samples from 132 cigarette smoking infertile men and 70 normal fertile controls, the former divided into a heavy-smoker group (> 20 cigarettes a day, n = 68) and a light-smoker group (< or = 20 cigarettes a day, n = 64). We performed computer-assisted semen analysis of the semen samples, and determined sperm PMI by flow cytometry after rinsing with PBS and staining by SYBR-14/PI, the sperm with normal PMI indicated as the percentage of those emitting green fluorescence (SYBR-14+/PI- %), dead sperm as the percentage of those emitting red (SYBR-14-/PI+), and moribund sperm as the percentage of those emitting both green and red (SYBR-14+/PI+).

RESULTSBoth the heavy- and light-smoker groups showed significant differences in SYBR-14-/PI+ % and SYBR-14+/PI- % from the normal controls (P < 0.01 or P < 0.05). SYBR-14+/PI- % was remarkably lower, while SYBR-14-/PI+ % markedly higher in the heavy-smoker than in the light-smoker group (P < 0.05). There was a significant correlation between SYBR-14+/PI- % and sperm motility (r = 0.938, P = 0.000).

CONCLUSIONSYBR-14/PI fluorescent staining and flow cytometry analysis could quickly and exactly detect sperm PMI. Cigarette smoking reduces sperm PMI and consequently sperm motility, which might be an important factor of male infertility.

Objective: The research is to provide the basis for effective protection and wise utilization of the plants resources inTea Mountain National Ecological Demonstration Area of Shandong Province. Methods: The general investigation on plant species inTea Mountain was conducted. The research scope covered plant species, their distribution in wild, community structure and flora.Results: A total of 352 higher plants, belonging to 250 genera and 90 families, were recorded. Four species were listed as nationalsecond-grade protected plants. Regional vegetation is Pinus thunbergii plantation and Secondary forest. The main forest vegetation isPinus thunbergii community. Pantropic types and N. Tem types are dominant types. The latitude and "the islands-effect" should be themajor-effect factor of this pattern. Because of intense artificial active disturbance, primary vegetation types in this region have sufferedserious destruction, especially the rare and precious plants that are at high risk of dying out. Conclusions: This regional communitystructure is simple. The shrub layer and the liana layer are undeveloped. The syngenesis time is short.
