【Objective】 To analyze the effects of different fortified feeding methods on nutritional metabolism and growth rate of preterm very low birth weight infants (VLBWI), in order to provide new clues for improving the prognosis of the preterm infants. 【Methods】 A total of 115 cases of premature VLBWI admitted to Department of Neonatology, The First Affiliated Hospital of Kunming Medical University from January 2019 to December 2020 were included in this study, and were divided into fortified breastfeeding group (HFM group), mixed feeding group, and premature formula feeding group (PF group) based on their feeding methods. The effects of different feeding methods on the nutritional metabolism and growth rate of premature VLBWI were analyzed. 【Results】 1) The hospitalization time of infants in the HFM group was shorter than that in PF group and mixed feeding group (t=7.185, 6.924, P<0.05). 2) The proportion of necrotizing enterocolitis (NEC) in the HFM group during hospitalization was lower than that in the PF group (P<0.05); the proportions of late onset septicemia(LOS) and extra uterine growth restriction(EUGR) in the HFM group during hospitalization were lower than those in the PF group (χ²=5.030, 4.147, P<0.05); the proportion of LOS was lower than that of the mixed feeding group(χ²=6.589, P<0.05). 3) During hospitalization, the proportions of abdominal distension, bloody stools and increased eosinophils in the HFM group were lower than those in the PF group (P<0.05), which in mixed feeding group was lower than those in PF group (Fisher exact test, P<0.05). 4) At discharge, the weight and length growth rate of the HFM group were higher than those of the mixed feeding group (t=3.722, 0.425, P<0.001) and the PF group (t =6.015, 0.496, P< 0.001). 【Conclusion】 Fortified breastfeeding can more effectively increase the growth rate of VLBWI in premature infants, improve nutritional metabolism, reduce complications and adverse feeding reactions related to premature infants, and is safer and more effective.

Objective To investigate the changes in distribution of Oncomelania hupensis snails in forestlands in Songjiang District, Shanghai Municipality from 2009 to 2023, so as to provide insights into formulation of O. hupensis snail surveillance programs. Methods The reports on O. hupensis snail surveillance in Songjiang District, Shanghai Municipality from 2009 to 2023 were collected, and the snail surveillance data in forestlands were extracted. The trends in the proportion of areas with snails in forestlands in total areas with snails, occurrence of frames with living snails and density of living snails were evaluated using a Joinpoint regression model in Songjiang District from 2009 to 2023, and the annual percent change (APC) and average annual percent change (AAPC). Results A total of 40 sites with snails were found in forestlands in 14 administrative villages of 4 townships, Songjiang District, Shanghai Municipality from 2009 to 2023. A total of 39 065 frames were surveyed for snails in settings covering an area of 609 600 m², and there were 6 084 frames with snails, covering 151 250 m² snail habitats. A total of 22 210 snails were captured, with the highest density of 260.00 snails/0.1 m², and 6 262 snails were dissected, with no Schistosoma japonicum infection identified in snails. The proportion of areas with snails in forestlands in total areas with snails appeared a tendency towards a rise in forestlands in Songjiang District, Shanghai Municipality from 2009 to 2023 (APC = AAPC = 24.9%, P > 0.05); however, there were no turning points in the trend curve, with the highest proportion seen in 2009 (53.81%), the lowest in 2011 and 2023 (both 0) and a mean proportion of 24.81%. The occurrence of frames with living snails appeared a tendency towards a rise from 2009 to 2023 (APC = AAPC = 41.5%, P > 0.05); however, there were no turning points in the trend curve, with the highest occurrence in 2009 (53.81%), the lowest in 2011 and 2013 (both 0), and the mean occurrence of 15.57%. In addition, the density of living snails appeared a tendency towards a rise from 2009 to 2023 (APC = AAPC = 55.0%, P > 0.05); however, there were no turning points in the trend curve, with the highest density in 2023 (0.96 snails/0.1 m²), the lowest in 2011 and 2013 (both 0), and a mean density of 0.57 snails/0.1 m². Conclusions The difficulty in O. hupensis snail control and risk of imported snails appeared a tendency towards a rise in forestlands in Songjiang District, Shanghai Municipality over years from 2009 to 2023. Supervision and assessment prior to seedling transplantation and intensified surveillance post-transplantation are recommended to reduce the risk of O. hupensis snail importation and spread.

ObjectiveTo analyze the monitoring results and trends of Oncomelania in Songjiang District of Shanghai from 2007 to 2023， and to provide reference for future monitoring work. MethodsThe data of snail monitoring in Songjiang District from 2007 to 2023 were collected， including the location of snail spots， the number of survey frames， the area with snails， the number of frames with snails， the total number of snails， etc. The density of living snails and the occurrence rate of living snail frames were calculated. ResultsFrom 2007 to 2023， a total of 158 snail spots were found in 22 administrative villages in 4 towns in Songjiang District， including 131 emerging snail habitats （82.91%） and 27 reemerging snail habitats （17.09%）. The total snail area was 175 980 m²， the number of snail frames was 10 061， and 33 302 snails were captured. The highest density was 260/0.11 m²， and 15 662 snails were dissected. No positive snails were found. The average density of living snails was 0.60/0.11 m² and the average occurrence rate of living snail frames was 17.99%. The snail areas in different areas were Yexie Town 126 000 m² （71.60%）， Maogang Town 26 470 m² （15.04%）， Xinbang Town 17 040 m² （9.68%）， and Shihudang Town 6 470 m² （3.68%）. The average density of living snails in different areas was 0.89/0.11 m² in Yexie Town， 0.65/0.11 m² in Maogang Town， 0.26/0.11 m² in Shihudang Town and 0.24/0.11 m² in Xinbang Town. The snail areas of different snail habitats were as follows： woodland 151 250 m²（85.95%）， river 13 810 m²（7.85%）， ditch 6 910 m²（3.93%）， farmland 4 010 m²（2.28%）. The average density of living snails in different snail habitats： ditch 1.01/0.11 m²， beach 0.86/0.11 m²， woodland 0.57/0.11 m²， river 0.40/0.11 m². The occurrence rate of living snail frames in different regions and different snail environment types showed a downward trend and the difference was statistically significant. ConclusionAlthough the snail monitoring indicators such as snail area， average living snail density and average living snail frame occurrence rate in Songjiang District are still at its historically low level， the average living snail density and average living snail frame occurrence rate are still high compared with other regions or the national average. We should focus on the upper reaches and tributaries of the Huangpu River， especially the key areas of seedling transplantation， and strengthen monitoring and supervision to reduce the risk of snail input.

Objective:To explore the relationship of infertility-related stress and depression of infertility women, and the effect of coping style and resilience in it.Methods:A cross sectional study was conducted in 230 infertility women who treated with Assisted Reproductive Technology in Reproductive Medical Center of the First Affiliated Hospital of Soochow University using convenience sampling method from April 2020 to April 2021 with self-made general information questionnaire, Fertility Problem Inventory, Simplified Coping Style Questionnaire, 10-item Connor-Davidson Resilience Scale and Patients' Health Questionnaire Depression Scale-9 item. And correlation and effect analysis was conducted.Results:Two hundred and nineteen questionnaires were finally collected, the effective recovery rate was 95.2%(219/230). The score of Fertility Problem Inventory was (136.21 ± 27.38) points, the score of Simplified Coping Style Questionnaire was (34.26 ± 7.66) points, the score of 10-item Connor-Davidson Resilience Scale was (27.50 ± 6.78) points, the score of Patients' Health Questionnaire Depression Scale-9 item was (4.26 ± 3.83) points. Correlation analysis results showed that infertility-related stress of infertility women was positively correlated with negative coping ( r=0.20, P<0.01) and depression ( r=0.26, P<0.01), negative coping was positively correlated with depression ( r=0.23, P<0.01). Effect analysis results showed that negative coping had a partial mediating effect between infertility-related stress and depression, and the mediating effect size was 0.05, accounting for 15.63% of the total effects. Resilience moderated the second half path of the mediation relationship ( β=-0.137, t=-2.11, P<0.05). Conclusions:The infertility-related stress is a positive predictor of depression. Negative coping has a mediating effect between infertility-related stress and depression, and resilience moderates the effect of negative coping on depression.

Objective:To establish the normal reference range of the ratio of fetal umbilical venous flow rate to umbilical artery pulsatility index (VAI).Methods:A total of 816 normal fetuses underwent prenatal examination and delivery were randomly selected from October 2018 to December 2020 in Maternal and Child Health Hospital of Guangxi Zhuang Autonomous Region. Fetal weight was obtained by measuring fetal biparietal diameter, head circumference, abdominal circumference, and femoral length.Umbilical venous flow (Quv) was measured. Umbilical artery pulsatility index (UA-PI) was obtained in the free segment of amniotic fluid. Quv was standardized according to fetal size to calculate the umbilical venous flow rate (nQuv) and VAI. The association between Quv, nQuv, UA-PI, VAI and the fetal gestational week were analyzed using correlation analysis. VAI was presented as ± s, the upper limit of 95% reference value and the lower limit of 5% reference value were taken as the standards of VAI increase and decrease, respectively. Twenty-six fetuses whose VAI were lower than limit of 5% and 20 fetuse whose VAI were than limit of 95% were chosed as the case group. Results:①Fetal Quv was positively correlated with gestational week ( r=0.893, P<0.001), nQuv and UA-PI were negatively correlated with gestational week ( r=-0.552, -0.827; all P<0.001), and VAI had no significant correlation with gestational week ( r=0.000, P=0.758); ②The mean, standard deviation, lower 5% reference value, and upper 95% reference value of VAI were 195.81, 55.61, 105.95, and 293.33, respectively; ③In the cases with abnormal VAI, 26 fetuses with reduced VAI, of whom there were 16 cases of maternal hypertension, and 13 cases complicated by severe preeclampsia; 1 case with 40 turns of umbilical cord torsion, 3 cases of stillbirth, 16 cases of preterm delivery, 19 cases of low neonatal birth body weight, 4 cases of 1-min Apgar score ≤7, 6 cases of umbilical artery blood pH<7.2, and 1 case without abnormalities in fetus during pregnancy and follow-up newborn. Among the 20 fetuses with increased VAI, there were 10 cases of fetal severe thalassemia, 2 cases of thalassemia, 1 case of sacrococcygeal teratoma, 1 case of portal venous shunt, 3 cases of placental chorioangioma, and 3 cases without abnormalities in fetus during pregnancy and follow-up newborn. Conclusions:The measurement and calculation of fetal VAI is simple and easy to perform. As a comprehensive index, fetal VAI remains constant in mid and late pregnancy, facilitates the follow-up of abnormal fetuses, and has potential clinical application.

An epidemic prevention and control team was established in the center, the team carried out the epidemic prevention and control with the opening of health records and by using "doctors around" APP. The center also opened the intelligent voice return visits, the 24-hour service hotline, and WeChat public column to provide consultation for the community residents; it also strentherned pre-check triage, realized the medical insurance sharing and the other measures. All these measures enabled the residents to have a correct understanding of the epidemic situation, eased their psychological panic, enhanced their sense of gain, and made residents more convenient to seek medical treatment nearby reducing interpersonal contact and aggregation, reduced the risk of cross-infection, and achieved accurate health management among community residents during COVID-19 epidemic.

Objective:To evaluate an intelligent voice call system in popularizing knowledge of prevention and control of Coronavirus Disease 2019 (COVID-19) for chronic disease patients in the community.Methods:An intelligent voice call system for popularization of scientific knowledge of COVID-19 and protective measures was developed in Fangzhuang Community Health Service Center of Beijing Fengtai district, in which 12 popular education modules ware designed and 3-6 core points were extracted from each module. During January 23 to January 29, 2020, the system was applied to send voice calls and text messages to all contracted chronic disease patients in Fangzhuang community with popular science education in different time points. Using equidistant sampling method, 400 participants were selected from the patients of successful voice outbound calls. The intelligent voice outbound system was used to investigate the participants′ COVID-19 knowledge levels, the main sources of knowledge and satisfaction with education. The outbound results of the above indicators were queried from the database of the intelligent voice outbound system.Results:A total of 98 487 voice outbound calls were effectively connected, the average call duration per person was 2.24 minutes, and the total call duration was equivalent to 488.5 workdays. A total of 141 201 messages were sent, with a read rate of 97.8% (141 201/144 405) . After the voice outbound education, the participants′ scores in answering the questionnaire on 12 popular science knowledge modules ware all significantly increased compared to those before the education ( t=22.4, 27.5, 24.3, 31.2, 25.6, 18.9, 22.5, 27.3, 28.1, 26.4, 15.2, 22.6, all P<0.01) ; 94.8% (235/248) of participants′ knowledge of COVID-19 mainly came from voice call. In addition, the patient′s overall satisfaction with the application of the intelligent voice call system for popularizing science education was 90.8% (225/248). Conclusions:The knowledge levels of COVID-19 and its prevention and control measures effectively have been improved among the community chronic disease patients with the application of an intelligent voice outbound system. Moreover, this mode is highly acceptable to patients, which would be introduced to other urban communities in China.
