Endemic situation of schistosomiasis in Suzhou City from 2010 to 2020 / 中国血吸虫病防治杂志

Objective To analyze the endemic status of schistosomiasis in Suzhou City from 2010 to 2020, so as to provide the evidence for formulating the future schistosomiasis control strategy. Methods The data pertaining to the endemic status of schistosomiasis in Suzhou City from 2010 to 2020 were retrieved from the annual schistosomiasis control report, the information management platform of schistosomiasis (parasitic diseases) in Jiangsu Province and the Parasitic Diseases Control Information Management System of Chinese Center for Disease Control and Prevention, including snail survey data, snail control data and schistosomiasis examination data, and were retrospectively reviewed. Differences of proportions were tested for statistical significance with chi-square test, and the trends in proportions were evaluated using the chi-square test for trends. Results Elimination of schistosomiasis was achieved in Suzhou City in 2018, and there were 3.528 9 million residents living in schistosomiasis-endemic villages of 81 townships in 9 counties. A total of 707 600 labor-days were used for snail survey in 11 586 village-times in Suzhou City from 2010 to 2020, covering 18 572.73 hm2, and snail habitats were detected with an area of 68.61 hm2, including emerging snail habitats of 37.30 hm2. A total of 23 144 snails were dissected, and no Schistosoma japonicum infection was detected. Reemerging and emerging snail habitats were predominantly found in inlands. During the period from 2010 to 2020, snail control was performed in Suzhou City for 71 000 labor-times, and snail control was done covering 269.34 hm2 through chemical treatment and covering 3.48 hm2 through environmental improvements. A total of 674 002 person-times received serological tests for S. japonicum infections in Suzhou City from 2010 to 2020, with seroprevalence of 0.38%, and a total of 33 835 person-times received stool examinations, with no egg-positives identified. The sero-prevalence of S. japonicum infections appeared an overall tendency towards a rise in Suzhou City from 2010 to 2020 (χ2 = 129.48, P < 0.001). The sero-prevalence of S. japonicum infections appeared high among local residents in 2016, and remained stable in other years, while the sero-prevalence of S. japonicum infections appeared an overall tendency towards a rise among mobile populations (χ2 = 54.11, P < 0.001). There were 278 800 and 175 202 serological tests among local residents and mobile populations in Suzhou City from 2013 to 2020, and 0.50% and 0.35% sero-prevalence rates were detected, respectively. The sero-prevalence of S. japonicum infections was significantly higher among local residents than among mobile populations in Suzhou City (χ2= 54.76, P < 0.001). Conclusions There is a risk of rebound of schistosomiasis in Suzhou City. Integrated control should be reinforced to prevent the risk of rebound of schistosomiasis in Suzhou City.

Effect of Chinese herbal medicine in the natural cycle of frozen embryo transfer / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To study the effect of Chinese herbal medicine on the clinical pregnancy rate and implantation rate of frozen embryo transfer (FET) in a natural cycle.</p><p><b>METHODS</b>Women with frozen embryos planned to receive FET and had spontaneous ovulation in a natural cycle were chosen for observation. They were assigned to the treated group and the control group, both were treated with conventional medicine in the very month of FET, but to the treated group, Chinese herbal medicine was given additionally. The clinical pregnant rate, implantation rate, endometrial thickness during transferring, as well as the levels of estrogen and progesterone 2 weeks after transfer in the two groups were observed and compared.</p><p><b>RESULTS</b>The clinical pregnancy rate and implantation rate in the treated group were significant higher than those in the control group, 47.37% (36/76 cases) vs 32.14% (54/168 cases) and 22.38% (47/210 embryos) vs 16.09% (74/460 embryos), respectively (all P <0.05). Difference between the two groups in endometrial thickness, levels of estrogen and progesterone showed no statistical significance (P > 0.05).</p><p><b>CONCLUSION</b>Chinese herbal medicine could enhance the clinical pregnancy rate and implantation rate in the natural cycle of FET to certain extent.</p>

Effect of Gutai Decoction on the abortion rate of in vitro fertilization and embryo transfer / 中国结合医学杂志

<p><b>OBJECTIVE</b>To study the effect of Chinese herbal medicine Gutai Decoction (GTD) on the abortion rate of in vitro fertilization and embryo transfer (IVF-ET).</p><p><b>METHODS</b>Observed were two hundred and forty-seven women having received IVF-ET and with beta-human chorionic gonadotropin (beta-HCG) > 25 IU/L on the 14th day after transferring.
