Abstract: Objective　To analyze the influencing factors of mother-to-child transmission of hepatitis B virus after combined immunological blockade, and to evaluate the effect of mother-to-child blockade, and to provide a basis for health policies and health interventions for preventing mother-to-child blockade of hepatitis B virus. Methods A total of 11 363 pairs of HBsAg positive pregnant women and their infants aged 7-12 months in Hainan Province from 2015 to 2020 were included in the study. The general situation, the situation of health care and delivery in this pregnancy and perinatal period, the detection of hepatitis B markers, the situation of antiviral therapy, the general situation of mother and infant during delivery and the implementation of blockade measures for mother-to-child transmission of hepatitis B were collected and analyzed. Results Among the 11 363 pairs of HBsAg positive pregnant women and their infants delivered in hospitals in Hainan province from 2015 to 2020, the positive rate of HBsAg in children at 7-12 months after birth was 1.47 %, and the difference in HBsAg positive rate of infants born in different years was not statistically significant (P>0.05). There were no significant differences in the positive rate of HBsAg among children born to pregnant women with different nationalities, educational levels, occupations, delivery modes, delivery places, obstetric operations and perineal laceration, abnormal perinatal period, children with different genders and premature delivery and perinatal (all P<0.05). There was significant difference in HBsAg positive rate among infants born to pregnant women of different ages, the positive rate of HBsAg of infants born to young pregnant women was higher than that of older pregnant women (P<0.05). The rate of antiviral therapy was low in HBeAg positive pregnant women, and the positive rate of HBsAg in their infants was 2.54%, which was higher than 0.83% in HBeAg negative pregnant women (P<0.05). Conclusions Combined immunological blockade with hepatitis B vaccine and hepatitis B immunoglobulin can effectively prevent the mother-to-child transmission of HBV. HBsAg-positive women can give birth at the right age, and HBeAg-positive pregnant women can be treated with antiviral therapy to block mother-to-child transmission, providing the important basis for the formulation of hepatitis B prevention and control strategies and measures.

Abstract: Objective To analyze the effect of nutrition package on the nutritional status and prevalence of children in rural areas of Hainan Province, and provide scientific basis and suggestions for further improving the nutritional and health status of children in this region. Methods　Four cities and counties were randomly selected as the intervention group, and four cities and counties matched with the intervention group in terms of population, economy, social culture, maternal and child health work foundation of township health centers, physical nutrition and health status were selected as the control group.With the combination of monitoring and prospective cohort study, infants in the intervention group and the control group were studied from June 1, 2020, and they were intervened for 12 months with supplementary food nutrition package. Before and after intervention, the nutrition and health status of infants aged 6-24 months in the intervention group and the control group were investigated to evaluate the nutritional and health effects of supplementary food nutrition package for infants aged 6-24 months in rural Hainan Province. Results　A total of 999 infants were investigated, including 427 in the intervention group and 572 in the control group. After 12 months of nutritional intervention, there was no significant difference in weight-for-age Z-score (WAZ) and height-for-age Z-score (HAZ) and weight-for-height Z-score (WHZ) between the intervention group and the control group (P>0.05). The rate of emaciation of the intervention group was 1.64%, which was significantly lower than 3.67% of the control group (P<0.05). There were no significant differences in the rate of growth retardation (2.81% and 3.32%, respectively) and underweight (0.47% and 1.92%, respectively) between the intervention group and the control group (P>0.05). The rate of respiratory infection and diarrhea in the intervention group were 9.13% and 1.17%, which were significantly lower than corresponding 23.25% and 3.15% in the control group (P<0.05). The hemoglobin of the intervention group and the control group were 117.24 g/L and 114.51 g/L respectively, and the rates of anemia were 11.11% and 22.84% respectively, the differences were statistically significant (P<0.05). Conclusions　The intervention of nutrition package in rural areas of Hainan Province has achieved the expected results, and supplementary food nutrition package has reduced the incidence of malnutrition and respiratory infection and diarrhea in recent two weeks in infants and anemia to a certain extent. We should attach great importance to the supplementary nutrition package for right-age children and promote the growth and health of children in rural areas through supplementary nutrition package, and continuously improve the nutrition and health level of children in Hainan Province.

OBJECTIVETo study the regulation of luteolin on spleen cells and sarcoma S180 cells in normal ICR mice.

METHODSSpleen cells and S180 cells were incubated with different concentrations of luteolin (50, 100, 200, and 400 μmol/L). The effect of luteolin on spleen cells and sarcoma S180 cells was determined by MTT assay. The apoptosis was detected using propidium iodide staining flow cytometry. Intracellular reactive oxygen species (ROS) was determined by flow cytometric analysis. Activities of free radicals scavenging were determined by hydroxyl radical and DPPH tests.

RESULTSCompared with the solvent control group, 200 and 400 μmol/L luteolin increased the spleen cells viability (P < 0.05). Luteolin at 100, 200, and 400 μmol/L decreased activities of S180 cells (P < 0.01). The proportion of sub-G1 phase spleen cells was reduced after treated with 200 and 400 μmol/L luteolin (P < 0.05). The proportion of sub-G1 phase S180 cells was elevated after treated with 200 and 400 μmol/L luteolin (P < 0.05). Compared with the solvent control group, levels of intracellular ROS in spleen cells of ICR mice all increased; levels of intracellular ROS in S180 cells all decreased after treated with 50, 100, 200, and 400 μmol/L luteolin (P < 0.05). Luteolin scavenged hydroxyl radical and DPPH in a dose dependent manner.

CONCLUSIONLuteolin had bilateral regulation on viability and apoptosis of spleen cells and S180 cells (promoting the viability of spleen cells, inhibiting apoptosis of spleen cells, inhibiting the viability of S180 cells, and promoting apoptosis of S180 cells), which was worth further study and exploration.

Abstract: Objective To compare the diagnostic efficacy of the upgraded version of the GeneXpert automated fluorescent quantitative PCR system (GeneXpert MTB/RIF Ultra, GeneXpert Ultra) and the original version of the GeneXpert system (GeneXpert MTB/RIF, Xpert), real-time fluorescent quantitative nucleic acid detection (FQ-PCR), real-time fluorescent thermostatic amplification of Mycobacterium tuberculosis RNA (SAT-RNA), real-time fluorescent thermostatic amplification detection of DNA (thermostatic amplification method) and traditional BACTEC MGIT 960 liquid culture (culture method) for special specimens of tuberculosis, in order to analyze its application value in clinical detection. Methods Using prospective research methods, a total of 170 special specimens (including 47 pleural and ascites effusion samples, and 34 24-hour urinary sediment specimens, 49 tissue specimens and 40 fester specimens) were collected i'an Chest Hospital from January to September 2021. GeneXpert Ultra, Xpert, FQ-PCR, SAT-RNA, isothermal amplification, and traditional culture were used for detection. Clinical diagnosis was used as the standard, and sensitivity, specificity, positive predictive value, negative predictive value, coincidence rate, and Kappa value were compared among the methods. Results The sensitivities of GeneXpert Ultra, Xpert, FQ-PCR, SAT-RNA, isothermal amplification, and traditional culture were 65.18% (73/112), 49.11% (55/112), 37.50% (42/112), 19.64% (22/112), 8.04% (9/112), and 22.32% (25/112), respectively. The sensitivity of GeneXpert Ultra was higher than that of the other five methods, and the differences were statistically significant (χ2=66.25, 42.10, 28.89, 13.09, 4.92, 15.18, all P<0.05). GeneXpert Ultra result analysis showed that: 5.48%(4/73) cases had trace, that is, trace Mycobacterium tuberculosis load, 79.45% (58/73) cases were extremely low, 10.96% (8/73) cases were low, 2.74% (2/73) were medium, , and 1.36% (1/73) were high load. In 4 trace samples, the Xpert detection was negative for all. Of the 73 GeneXpert Ultra positive reports, 63 were rifampicin-sensitive, 6 were rifampicin-resistant, and 4 were rifampicin-resistant but of unclear resistance. Of the 55 Xpert positive reports, 45 were rifampicin-sensitive, 2 were rifampicin-resistant, and 8 were rifampicinresistant but of unclear resistance.. Conclusions The new generation of GeneXpert MTB/RIF Ultra has high sensitivity, specificity and drug resistance detection rate, and its advantage is even more apparent in the pathogenic diagnosis of special specimens of tuberculosis. It can be used as one of the preferred methods in samples with low bacterial load.

BACKGROUND: Adiponectin is one of the adipocytokines that have been found to be negatively correlated with obesity in recent years. As an endogenous bioactive peptide, adiponectin is shown to be associated with insulin resistance, type 2 diabetes mellitus, metabolic syndrome, and participate in the regulation of bone metabolism. OBJECTIVE: To describe the mechanism of adiponectin in bone metabolism, and mainly clarify the correlation of adiponectin with osteoblasts and osteoclasts. METHODS: The first author searched PubMed and CNKI databases for the articles addressing the experimental research and research progress of adiponectin in bone metabolism published from 2003 to 2017. The keywords were "adiponectin, osteoporosis, bone metabolism, osteogensis, bone absorption" in English and Chinese, respectively. Adiponectin, its receptors, bone metabolism, adiponectin effects on bone formation and bone resorption were reviewed. RESULTS AND CONCLUSION: Adiponectin exerts a comprehensive effect on bone metabolism, mainly through autocrine, paracrine and endocrine, insulin signaling pathways. Besides, it exerts biological effects mostly by regulating OPG/RANKL/RANK system, especially in bone formation and bone resorption. Therefore, adiponectin may prevent osteoporosis by regulating bone metabolism.
