Abstract: Objective To explore the trend of maternal mortality in Hainan Province during the period of 2003-2022, both in the province and in urban and rural areas, and to forecast the maternal mortality rate for the period 2023-2025. Methods The 2003-2022 data collected from Hainan Province's three-tier network for maternal mortality surveillance was examined using the Chi-square test for trend (CMH) to analyze the province-wide and urban-rural maternal mortality trends. The time series model forecasting using exponential smoothing was used to predict the maternal mortality rate in Hainan Province from 2023 to 2025. Results From 2003 to 2022, a total of 201 011 616 live births and 463 maternal deaths were reported in Hainan Province, with a maternal mortality rate of 23.03 per 100 000. Over 20 years, the maternal mortality rate in Hainan Province showed a downward trend, with an annual rate of decline of -4.13%. The rate decreased significantly during this period.. From 2003 to 2022, the maternal mortality rate in rural areas of Hainan Province was 25.74/100 000 (373/1 448 943), and it was significantly higher than that in urban areas, 16.04/100 000 (90/561 173). In the first 10 years, the gap between urban and rural areas progressively reduced, but it widened significantly in the last decade, especially after 2017. The maternal mortality rate was significantly lower in urban than rural areas, and the differences had statistical significance. The annual rates of decline in maternal mortality in Hainan Province and in urban and rural areas from 2003 to 2022 were -5.0% and -3.71%, respectively, showing a negative growth with the decrease rate in rural areas lower than urban areas. The maternal mortality rate in Hainan Province showed a fluctuating downward trend, different from the stable trend of national decrease. The mortality rates for direct obstetric causes of death (233 cases) and indirect obstetric causes of death (230 cases) were 11.59/100 000 and 11.44/100 000, respectively. The results of the maternal mortality review showed a predominance of avoidable deaths (315 cases, 68.03%). Brown's cubic exponential smoothing predicted the maternal mortality rate in Hainan Province for 2023-2025 as 9.45/100 000, 8.17/100 000, and 6.89/100 000. Conclusions The maternal mortality rate in Hainan Province is largely influenced by maternal deaths in rural areas, and maternal health care in rural areas should be emphasized. Measures such as intervening to address the main factors influencing avoidable maternal deaths, strengthening high-risk maternal management, improving the level of critical maternal care, and providing subsidies for critical maternal care can sustainably reduce the maternal mortality rate in Hainan.

Aim To explore the mechanism of cryptotanshinone (CTS) against non-small cell lung cancer (NSCLC) by using network pharmacology and bioinformatics methods. Methods Taking CTS as the research object, TCMSP database, SwissTargetPrediction and PharmMapper target prediction platform were used to collect CTS related targets; OMIM database, Gene-Cards data-base and TCGA database were employed to collect NSCLC related targets; String database and Cytoscape software were applied to construct PPI of intersection targets Network diagram, the hub targets were screened out, and AutoDock Vina was used for molecular docking verification; the R language clusterProfiler package was used to perform GO and KEGG enrichment analysis on the intersection targets; Cytoscape software was employed to construct the "CTS intersection targets-KEGG pathway" network. Results As a result, 75 intersecting targets were obtained, mainly involving various biological processes such as signal transduction, phosphorylation and dephosphorylation, apoptosis and vascular regulation, mainly through pancreatic cancer, colorectal cancer, cancer pathways and JAK-STAT signaling pathways. And cellular pathways such as apoptosis and natural killer cell-mediated cytotoxicity exerted their anti-NSCLC effects. Conclusions CTS exerts its anti-NSCLC effect through multiple targets and multiple pathways, which provides the theoretical support for further in-depth research.

Objective:To investigate the correlation between preeclampsia and thyroid dysfunction in pregnancy.Methods:107 early pregnant women with preeclampsia admitted to our hospital from Jan. 2017 to Jan. 2020 were all enrolled (observation group) . The observation group were in 6-34 gestational weeks, with an average parity of (1.67±0.35) times. In addition, 100 cases of normal pregnant women in the same period were selected as the control group. The control group were in 6-34 gestational weeks, with an average parity of (1.61±0.31) times. The two groups were compared at early, mid and late pregnancy in terms of thyroid function, and the correlation of preeclampsia and abnormal thyroid function was analyzed.Results:1. TSH levels in the observation group were (1.92±1.24) , (2.07±0.82) , and (2.30±1.23) mU/L in the first trimester, second trimester and third trimester, respectively, showing an upward trend. The difference between the two groups was statistically significant ( P=0.024) . FT4 levels of the observation group in the first trimester, second trimester and third trimester were (0.80±0.26) , (0.60±0.34) and (0.59±0.32) pmol/L, respectively, showing a decreased trend and the difference was statistically significant compared with those of the control group ( P=0.012) . 2. The incidence of hypothyroidism, TPOAb positive and reduced free tetraiodothyronine in the observation group was significantly higher than that in the control group ( P=0.001, 0.023, 0.005) . There was no significant difference in the incidence of hyperthyroidism or subclinical hypothyroidism between the two groups ( P=0.169, 0.846) . 3. Correlation analysis showed that preeclampsia was related to hypothyroidism, normal thyroid function with TPOAb positive and reduced free tetraiodothyronine ( P=0.000, 0.000, 0.000) . Conclusions:There are changes in thyroid function in pregnant women with preeclampsia. Hypothyroidism, positive TPOAb and reduced free tetraiodothyronine are closely related to the onset of preeclampsia.

BACKGROUND:
We previously found that the intestinal epithelial chemokine (C-C motif) ligand 7 (CCL7) plays an important role in the development of toxin-induced acute liver damage. The detailed effects of intestinal epithelial CCL7 on chronic diseases; however, are still unclear. Here, we aimed to investigate the impact of intestinal epithelial CCL7 overexpression on high-fat diet (HFD)-induced obesity and steatohepatitis in mice.
METHODS:
Intestinal epithelial CCL7 overexpression (CCL7) mice and their wild-type (WT) littermates were fed with normal chow or HFD for 16 weeks to induce obesity and non-alcoholic fatty liver disease. Body weight gain, as well as adipose tissue index were assessed. Liver injury was monitored by histological analysis and real time polymerase chain reaction. Gut microbial composition was analyzed by 16S rRNA gene sequencing.
RESULTS:
We found that the CCL7 mice on a HFD had markedly decreased weight gain (8.9 vs. 17.0 g, P < 0.05) and a lower adipose tissue index that include mesenteric fat (1.0% vs. 1.76%, P < 0.05), gonadal fat (2.1% vs. 6.1%, P < 0.05), subcutaneous fat (1.0% vs. 2.8%, P < 0.05) compared to WT animals. HFD-induced glucose intolerance and insulin resistance were also significantly improved in CCL7 mice compared to WT. Furthermore, HFD-fed CCL7 mice displayed less hepatic lipid accumulation and lower expression of inflammatory factors than WT mice. 16S rRNA gene sequencing demonstrated that CCL7 overexpression in intestinal epithelial cells improved HFD-induced gut microbial dysbiosis.
CONCLUSIONS
Our study revealed that CCL7 overexpression in the intestinal epithelium protects mice against the progression of diet-induced obesity, hepatic steatosis, and enteric dysbiosis.
