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.

OBJECTIVE:To provide reference for rational drug use and strengthen the management of adjuvant medication man-agement in the hospital. METHODS:1 080 and 860 discharged medical records of 12 Vitamins for injection were selected from our hospital during Jun.-Nov. 2014 (pre-special comment group,i.e. group A) and Jun.-Nov. 2015 (post-special comment group,i.e. group B),respectively. The application of 12 Vitamins for injection,hospitalization stay,drug cost and the incidence of ADR were compared before and after adjuvant medication special comment. RESULTS:After adjuvant medication special comments,the propor-tion of drug use of no indication,unsuitable solvent selection,irrational drug dosage,drug use of drug interaction and contraindica-tion,drug cost and the incidence of ADR in group B were all lower than in group A,with statistical significance(P<0.05). There was no statistical significance in hospitalization stay between 2 groups(P>0.05). CONCLUSIONS:Clinical pharmacists adopt adju-vant medication special comments to effectively standardize clinical application of 12 Vitamins for injection in our hospital.

To mask the bitterness of azithromycin（AZI） and improve patient compliance, an AZI-loaded microsphere (AZI-EC MS) for oral administration was prepared by O/W emulsion solvent evaporation with ethylcellulose (EC) as carrier. The release profiles and taste-masking effect of AZI-EC MS were preliminarily assessed. Its physical properties and morphology were then investigated by differential scanning calorimetry (DSC), Fourier-transform infrared spectroscopy (FTIR) and scanning electron microscope (SEM). The results indicated that the polymer weight of EC could influence the drug release behavior. With a drug polymer ratio of 1∶1 and mixed EC (N22/T10, 7∶3) as carrier, the cumulative release of AZI-EC MS at 0.5 h was less than 40% and reached 90% at 8 h; the drug loading efficiency of microspheres was (48.95 ± 0.86)% with smooth spherical morphology. The AZI bitterness threshold is 9.93 μg/mL with a strong bitter taste, which indicated a better taste masking effect. Therefore, AZI-EC MS prepared in this study can mask AZI bitterness and improve patient compliance, setting the stage for the research of new AZI preparations.

Objective:To construct the molecular transmission network of human immunodeficiency virus type 1 (HIV-1) epidemic strains in northern Zhejiang Province (Jiaxing City and Huzhou City) and to explore the HIV-1 transmission characteristics in this region.Methods:A total of 371 newly diagnosed human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) patients in Jiaxing City and Huzhou City in 2017 were included as study subjects, and the blood samples were collected and the basic demographic and epidemiological information were obtained. RNA in plasma was extracted, and the pol region gene sequence was amplified by reverse transcriptase polymerase chain reaction (RT-PCR) and nested polymerase chain reaction (PCR) to construct phylogenetic tree for identifying subtypes. The pairwise genetic distances were calculated, and the optimal threshold of genetic distance was selected, and finally the molecular transmission network was constructed. Chi-square test was used for statistical analysis. Results:The pol region gene sequences of 336 samples were successfully obtained, and 11 subtypes were detected, mainly including circulating recombinant form (CRF)07_BC (40.8%, 137/336) and CRF01_AE (31.2%, 105/336). Based on the 1.0% genetic distance threshold, the molecular transmission network of HIV-1 was plotted. A total of 38 transmission clusters (cluster sizes ranging from two to 28) including 119 patients were found, with males predominantly (82.4%, 98/119) and most of the patients aged over 40 (include 40) years old (52.9%, 63/119), mainly infected with CRF07_BC subtype (57.1%, 68/119) and CRF01_AE (24.4%, 29/119). The clustering rate of CRF07_BC (49.6%, 68/137) was significantly higher than that of CRF01_AE (27.6%, 29/105), the difference was statistically significant ( χ2=5.27, P=0.022). Two large clusters C1 (28 cases) and C2 (11 cases) were identified, the majority of which were men who have sex with men (17 cases and seven cases, respectively). High-risk cases generally sought sexual partners in local or nearby cities through mobile phone dating software, of which the infected sequences mostly had high homology with other economic developed regions (Guangdong Province, Beijing City and Hangzhou City, etc.). Conclusions:The HIV-1 subtypes are diverse in Jiaxing City and Huzhou City, mainly CRF07_BC and CRF01_AE. The HIV-1 transmission networks are complex, among which high-risk cases may be the key factor leading to the HIV-1 epidemic in the region. Therefore, it is urgent to deepen the transmission network monitoring and formulate timely precise intervention and prevention strategies.

This study sought to assess the therapeutic effect of celecoxib (CEL)-loaded polylactic acid-glycolic acid copolymer (PLGA) microspheres on rheumatoid arthritis in rats after intra-articular injection.The celecoxib-loaded microspheres (CEL-MS) were prepared by the O/W solvent volatilization method with PLGA as carrier.In order to investigate the therapeutic effect of CEL-MS on rheumatoid arthritis in rats after intra-articular injection, a rat model of adjuvant arthritis (AA) was constructed by complete Freund''s adjuvant, and the evaluation indicators of the therapeutic effect were rat paw swelling, arthritis index,spleen index and joint synovial histopathological examination. The results showed that the microspheres had a smooth spherical morphology with a particle size of (2.1 ± 0.3) μm and a drug loading efficiency of (20.8 ± 0.6)%.The results of the in vivo efficacy test showed that intra-articular injection of CEL-MS compared to the CEL suspension oral and the celecoxib suspension intra-articular injection in adjuvant arthritis rat model can significantly reduce joint swelling and arthritis index, thus effectively inhibiting synovial inflammation.The above results indicate that intra-articular injection of CEL-MS has a good therapeutic effect on rheumatoid arthritis in rats.

Vitamin D deficiency is common in pregnant women, and it is associated with multiple gestational complications, fetal intrauterine dysplasia, and maternal and infant health in postpartum period. Vitamin D involved in lipid metabolism may affect maternal-fetal health during pregnancy through this biological pathway. This review provides an overview of three main aspects, including, the effect of vitamin D on the mechanism of lipid metabolism, the relationship between vitamin D and lipid metabolites in pregnant women and women with pregnancy complications. An association between vitamin D status and lipid metabolism at different stages of pregnancy has been justified in most current studies, and the underlying mechanism has also been partly elucidated. Given some gestational complications, such as gestational diabetes and pre-eclampsia, pregnant women with these conditions are often associated with abnormal lipid metabolism and vitamin D deficiency. There is no doubt that the studies on the vitamin D supplementation and lipid metabolism improvement could have crucial clinical significance for this population. More randomized controlled trials with multi-center, large sample and multi-dose interventions are needed in the future to provide scientific evidence for clinical practice.

Objective To understand the characteristics of distribution on HIV-1 subtypes and the transmission clusters in Yiwu in Zhejiang province.Methods A cross-sectional study of molecular epidemiology was carried out on newly reported H1V/AIDS cases in Yiwu.RNA was extracted from 168 plasma samples,followed by RT-PCR and nest-PCR for pol gene amplification,sequencing,phylogenetic tree construction used for analyzing the subtypes and transmission clusters.Mutations on drug resistance was analyzed by CPR 6.0 online tool.Results Subjects were mainly males (86.3％,145/168),with average age as (39.1 ± 13.4) years old and most of them were migrants (66.7％,112/168).The major routes of transmission included homosexual (51.2％,86/168) and heterosexual (48.8％,82/168) contacts.The rate of success for sequence acquisition was 89.9％ (151/168).The dominant subtypes showed as CRF01_AE (74,49.0％) and CRF07_BC (64,42.4％),followed by CRF08_BC (5,3.3％),CRF55_01B (3,2.0％),each case of subtype B,CRF45_cpx,CRF59_01B,CRF85_BC and URF (B/C).CRF45_cpx and CRF85_BC were discovered the first time in Zhejiang province.Twenty-six transmission clusters involving 65 cases were found,with the total clustered rate as 43.0％ (65/151),in which the CRF01_AE clustered rate appeared as 54.1％ (40/74),higher than that of CRF07_BC (21/64,32.8％).The average size of cluster was 2.5 cases/cluster,with average size of cluster in CRF01_AE patients infected through heterosexual transmission as the largest (3.5 cases/cluster).The prevalence of transmitted drug resistance was 4.6％ (7/151).Seven cases with surveillance drug resistant mutations (SDRM) were found,including 5 cases of M46L (3.3％),and one case of F77L or Y181C.Conclusion HIV genetic diversity and a variety of transmission clusters had been noticed in this study area (Yiwu).Programs on monitoring the subtypes and transmission clusters should be continued and strengthened.

Objective: The purpose of this study was to investigate the state of depression and anxiety and assciated factors of back to school college students during the outbreak of COVID-19, so as to provide theoretical basis for emotional counseling and psychological crisis intervention after long term school closure due to epidemic outbreak. Methods: Cluster sampling was used to select the first batch of 2 697 back to school students in a high vocational college. The survey content includes basic information questionnaire, Depression Self rating Scale (SDS) and Anxiety Self rating Scale(SAS). Results: The detection rate of depression and anxiety was 31.8% and 10.4% respectively. Multivariate Logistic regression analysis showed that the risk of depression in female college students was 1.28 times higher than that in male students. The risk of depression among college students with family loss experience caused by the outbreak of COVID-19 was 1.30 times that of those without family loss experience caused by the outbreak of COVID-19. Outgoing personality(OR=0.62), neutral (OR=0.55) and mild temper(OR=0.46), moderate frequency of physical exercise per week(1-2 times:OR=0.73, 3-4 times:OR=0.65) were protective effects for depression in college students.Low frequency of breakfast were the risk effects for depression in college. The risk of anxiety among college students who was the only child in the family was 1.61 times higher than that who was not the only child in the family. The risk of anxiety among college students with family loss experience caused by the outbreak of COVID-19 was 1.45 times higher than that college students without family loss experience caused by the outbreak of COVID-19. Neutral temper, mild temper and physical exercise 1-2 times a week were associated with lower level of anxiety in college students(OR=0.67,0.56,0.67). Breakfast skipping (OR=2.03) was associated with higher levvel of anxiety in college students. Conclusion During the outbreak of COVID-19, the first batch of back to school college students presented high level of depression. Colleges are suggested to promptly carry out effective emotional relief and psychological intervention for students, especially those whose family suffered in COVID-19, the only child in the family, with poor breakfast eating habits, as well as breakfast skipping and lack of physical exercise.
