Abstract: Objective　To analyze the emergency response and long-term intervention effects after the detection of infectious snails epidemic by loop-mediated isothermal amplification (LAMP) assays in Hannan District, Wuhan City, and to explore the application of LAMP in early surveillance and early-warning of schistosomiasis transmission. Methods Snails picked up by the risk monitoring system in Hannan District were examined by anatomical microscopy and LAMP technology to identify the schistosomiasis infection. Emergency response and intensive intervention were initiated in the environment where positive snails appeared, and the long-term effects were evaluated. Results In May 2018, the infectious snails were detected by LAMP technology in Hannan District, and the positive snails were located in Zhujiacha, Dongzhuang Village, Obstacles and weeds were removed and buried by machine in Zhujiacha. 12 700 m2 of snails were killed by drugs, and the mortality rate of snails was more than 80%; no new seropositive persons were found in the emergency examination within 500 m of the positive snail sites. 506 people were examined in Dong Zhuang Village at the end of the year, and 30 positive IHA cases were detected with a blood positive rate of 5.93%, no positive fecal test was found, and all positive blood test patients took preventive medication. The monitoring results of sentinel rats and wild feces were all negative. Health education was carried out, 7 warning signs were deployed and refreshed, and 500 publicity brochures were distributed. After nearly three years of intensified intervention and monitoring in the villages where the positive environment is located, and the density of snails on the stubborn snail has dropped from 0.094/frame to 0.027/frame, and the positive rate of blood test in Dongzhuang Village has steadily dropped from 5.93% to 3.74%. Conclusions The infected snails missed by microscopy were detected by LAMP in Hannan District, which created conditions for the rapid emergency treatment of environment and elimination of positive snail and improved the sensitivity of the surveillance and early warning system in transmission-interrupted areas.

Objective: To compare the safety and efficacy of transmesenteric vein extrahepatic portosystemic shunt (TEPS) and transjugular intrahepatic portosystemic shunt (TIPS) in the treatment of cavernous transformation of the portal vein (CTPV). Methods: The clinical data of CTPV patients with patency or partial patency of the superior mesenteric vein treated with TIPS or TEPS treatment in the Department of Vascular Surgery of Henan Provincial People's Hospital from January 2019 to December 2021 were selected. The differences in baseline data, surgical success rate, complication rate, incidence rate of hepatic encephalopathy, and other related indicators between TIPS and TEPS group were statistically analyzed by independent sample t-test, Mann-Whitney U test, and Chi-square test. Kaplan-Meier survival curve was used to calculate the cumulative patency rate of the shunt and the recurrence rate of postoperative portal hypertension symptoms in both groups. Results: The surgical success rate (100% vs. 65.52%), surgical complication rate (6.67% vs. 36.84%), cumulative shunt patency rate (100% vs. 70.70%), and cumulative symptom recurrence rate (0% vs. 25.71%) of the TEPS group and TIPS group were statistically significantly different (P < 0.05). The time of establishing the shunt [28 (2141) min vs. 82 (51206) min], the number of stents used [1 (12) vs. 2 (15)], and the length of the shunt [10 (912) cm vs. 16 (1220) cm] were statistically significant between the two groups (t = -3.764, -4.059, -1.765, P < 0.05). The incidence of postoperative hepatic encephalopathy in the TEPS group and TIPS group was 6.67% and 15.79% respectively, with no statistically significant difference (Fisher's exact probability method, P = 0.613). The pressure of superior mesenteric vein decreased from (29.33 ± 1.99) mmHg to (14.60 ± 2.80) mmHg in the TEPS group and from (29.68 ± 2.31) mmHg to (15.79 ± 3.01) mmHg in TIPS group after surgery, and the difference was statistically significant (t = 16.625, 15.959, P < 0.01). Conclusion: The best indication of TEPS is in CTPV patients with patency or partial patency of the superior mesenteric vein. TEPS improves the accuracy and success rate of surgery and reduces the incidence of complications.

An imported case of acute schistosomiasis was reported in Wuhan City in 2020. The case was infected with Schistosoma by contact with the infested water due to playing water in the Yangtze River when working out of Hubei Province. The patient visited four medical institutions and the duration from onset to definitive diagnosis was 20 days. The patient’s low awareness of schistosomiasis prevention and control knowledge and lack of diagnosis and treatment awareness for schistosomiasis among medical institutions were considered as main causes of the development of acute schistosomiasis and progression to severe case. Intensifying schistosomiasis health education among mobile populations and improving the awareness and capability of early diagnosis of schistosomiasis among clinicians are recommended.

Objective To investigate the expression and correlation of visfatin, hsa-miR-199a and extracellular regulated protein kinase 1/2 (ERK1/2) in colorectal cancer (CRC) tissues. Methods The expression levels of visfatin mRNA and hsa-miR-199a were detected by Real-time PCR in 64 primary cases of radical resection of colorectal cancer who underwent pathological clinical examination in the clinicopathological examination in our hospital center from January 2017 to December 2017, the protein expression levels of visfatin and ERK1/2 were detected by immunohistochemistry and Western blotting. The relative expression levels of hsa-miR-199a in each group were compared according to the expression levels of visfatin and ERK1/2. Results The levels of visfatin gene and protein in colorectal cancer tissue (observation group, 64 cases) were higher than those in normal colorectal cancer (control group, 64 cases), and the expression was consistent. The colorectal cancer tissue(observation group) expression level of hsa-miR-199a was lower than that of normal colorectal tissue(control group), and visfatin mRNA was significantly negatively correlated. The colorectal cancer tissue (observation group) expression of ERK1/2 was higher than normal colorectal tissue (control group) and visfatin was significantly positively correlated. The relative expression of hsa-miR-199a in the visfatin and ERK1/2 positive group was significantly different from that in the test variables. Conclusion The overexpression of visfatin in colorectal cancer affects the down-regulation of hsa-miR-199a and is related to the ERK signaling pathway.

Objective To analyze the clinical outcomes of progestin primed ovarian stimulation (PPOS) compared with the other three different controlled ovarian hyperstimulation (COH) protocols in fresh embryo transfer (ET) and frozen-thawed embryo transfer (FET) cycles. Methods A total of 430 oocyte pick-up cycles and 272 FET cycles were retrospectively analyzed. Number of oocytes retrieved, laboratory indexes and pregnancy outcome of FET were compared. Results The mean oocytes retrieved (11.1±7.3), fertilization rate (85.6%), cleavage rate (95.1%) and excellent embryo rate (20.2%) as well as transplantable embryo rate (4. 5 ±3.1) of the PPOS group did not show significant differences compared with the other 3 subgroups (all P<0.05) in fresh cycle. As for pregnancy outcomes in FET cycles, no statistically significant differences were observed among the four groups in embryo implantation rate (26.2%), clinical pregnancy rate (63.0%) and abortion rate (11.8%) (all P<0.05). However, embryo implantation rate, clinical pregnancy rate was higher in PPOS group compared with the other groups. Conclusion Compared with the other three ovulation stimulation programme, PPOS might be used as a new alternative for controlled ovulation stimulation protocols.

Objective:To analyze active components， its targets and signaling pathways of Shenlian formula based on network pharmacology， and explore the molecular mechanism of Shenlian formula in the treatment of atherosclerotic cardiovascular disease （ASCVD）， in order to provide a basis for the rational interpretation of the prescription compatibility of Shenlian formula. Method:Major chemical compounds of the formula were obtained by SymMap and Systematic pharmacology database and analysis platform of Traditional Chinese Medicine （TCMSP）， its target proteins were obtained by SymMap and ETCM Databases， and the pathogenic genes responsible for of ASCVD were obtained by DisGeNET and GEO Datebases.

Proteins-proteins interactions （PPI） network was built through the String Datebase. The Cytoscape 3.6.0 was used to explore the key compounds and targets of Shenlian formula on ASCVD. Then gene ontology （GO） enrichment and Kyoto Encyclopedia of Genes and Genomes （KEGG） signaling pathway were analyzed to screen out the key targets of Shenlian Formula. Rat I/R model was adopted as representative disease model of ASCVD for experimental verification. Result:There were 59 candidate compounds， 67 predicted targets and 29 key targets of Shenlian formula on ASCVD. Key targets mainly included cyclooxygenase 2 （PTGS2）， estrogen receptor 1 （ESR1） and TP53. GO analysis showed that the biological functions of potential genes of Shenlian formula in treatment of ASCVD were mainly related to apoptotic， nitric oxide biosynthetic process， response to estradiol， angiogenesis， inflammatory response and oxidative stress and acute-phase response. KEGG pathway enrichment results showed that the pathways of potential genes of Shenlian formula in treatment of ASCVD mainly involved TNF signaling pathway， phosphatidylinositol-3 kinase （PI3K）/ protein kinase B （Akt） signaling pathway， hypoxia induction factor-1 （HIF-1） signaling pathway and apoptosis. Among them， the regulatory effect of Shenlian formula on apoptosis may act on not only TP53， but also different signaling pathways of apoptosis respectively， thus playing a synergistic effect. In vivo experimentation confirmed that Shenlian formula could significantly reduce the myocardial infarction area， improve the myocardial histopathological changes， and especially reduce myocardial mitochondrial injury. Further analysis showed that Shenlian formula can significantly inhibit the expressions of activated proteins in mitochondrial apoptosis pathway. Conclusion:Anti-atherosclerosis traditional Chinese medicine Shenlian formula could effectively intervene ASCVD， and its effect on mitochondrial apoptosis of myocardial cells is one of its mechanisms in protecting myocardial ischemia-reperfusion injury.
