Objective: To understand anxiety symptoms among medical college students and their relationship with social ecological risk factors, so as to provide reference for mental health promotion among medical students. Methods: From September to October 2021, a convenient cluster sampling method was used to include 1 274 freshmen to senior students of a medical school in Taiyuan City, and the Generalized Anxiety Disorder-7 and adolescent social ecological risk factors assessment questionnaire were used. Multivariate binary Logistic regression was used to analyze the association between anxiety symptoms and social ecological risk factors among medical students. Results: The overall detection rate of anxiety symptoms among medical students was 16.2%. The rate of anxiety varied significantly by grade (freshman: 19.9%, sophomore: 13.0%, junior: 14.0%, senior: 18.9% ) and number of friends (≤2: 22.8%, 3-5: 14.4%, ≥6: 11.8%) ( χ 2=8.70, 16.34, P <0.05). Spearman correlation analysis showed that individual, family, school, community, policy, culture, time, and total score in socio ecological risk factors were positively associated with anxiety symptom scores at different levels of risk ( r=0.33, 0.25, 0.32, 0.16, 0.15, 0.16, 0.16, 0.35, P <0.01). Logistic regression analysis showed that high risk for personal dimension of the socio ecological risk factors was positively associated with rate of anxiety symptoms among medical students ( OR=3.32, 95%CI =1.66-6.61), and remained positively associated ( OR=2.98, 95%CI =1.49-5.94) after adjusting for grade and number of friends ( P <0.01). Conclusions Exposure to high personal dimensions of socio ecological risk factors increases the risk of developing anxiety symptoms among medical students. A focus should be placed on the personal factors associated with anxiety to promote medical students mental health.

Objective To investigate the relationship between insomnia,gastrointestinal symptoms,and glycosylated hemoglobin(HbA1c)levels in individuals diagnosed with type 2 diabetes mellitus(T2DM),as well as the related influencing factors.Methods A total of 910 T2DM patients treated in our multicenter from January 2022 to December 2022 were enrolled in this study.General information(gender,age,smoking and drinking history,exercise,course of disease,treatment and complications),HbA1c,Athens Insomnia Scale(AIS)scores and Gastrointestinal Symptoms Rating Scale(GSRS)scores of patients were collected.The differences of sleep and gastrointestinal symptoms between groups were analyzed,and the correlation between the differences and HbA1c was analyzed.Furthermore,the risk factors for non-standard HbA1c were analyzed.Results The AIS score and GSRS score in the HbA1c control group were less than those in the non-standard group(P＜0.01).Insomnia was reported by 37.0％of T2DM patients,and the HbA1c level in the insomnia group was significantly higher than that in the non-insomnia group(10.00％±2.38％vs.8.26％±1.73％,P＜0.01).Gastrointestinal symptoms were present in 57.5％of T2DM patients,and the HbA1c levels in the group with gastrointestinal symptoms were significantly higher than those in the group without gastrointestinal symptoms(9.26％±2.23％vs.8.43％±1.98％,P＜0.01).Furthermore,26.3％of T2DM patients experienced both insomnia and gastrointestinal symptoms.Remarkably,the HbA1c levels in the group with both insomnia and gastrointestinal symptoms were significantly higher than those in the group without either condition(10.18％±2.44％vs.8.45％±1.86％,P＜0.01).Correlation analysis demonstrated a significant association between sleep quality,gastrointestinal function,and HbA1c levels(P＜0.01).The logistic regression analysis result revealed that age,GSRS score,AIS score,and the presence of insomnia combined with gastrointestinal symptoms were independent risk factors for predicting HbA1c≥6.5％(P＜0.01).Having both insomnia and gastrointestinal symptoms concurrently was the strongest risk factor for substandard HbA1c control,and the risk of blood sugar control may increase about 5 times when both appear together.Conclusion Insomnia and gastrointestinal symptoms are common comorbidities in T2DM patients,showing a cross-interfering relationship,and they appear together with poor blood sugar control,interact causally,and amplify each other.

Objective To analyze the situation of perinatal birth defects in 13 monitoring hospitals in Changsha City from 2011 to 2020, and to explore the composition characteristics and changes of birth defects in Changsha. Methods The monitoring data of perinatal birth defects in 13 surveillance hospitals in Changsha City from 2011 to 2020 were collected and statistically analyzed. Results From 2011 to 2020, the total number of perinatal infants in the 13 surveillance institutions in Changsha was 541,234, showing a trend of rising first and then falling. A total of 15 725 cases of birth defects were found, and the incidence rate of birth defects in perinatal period was 290.54/10 000. The incidence of birth defects in 2020 decreased by 41.93% compared with 2011. The incidence of perinatal birth defects in males (326.59/10,000) was higher than that in females (248.96/10 000), and the difference was statistically significant (χ²=288.955, P＜0.05). The incidence of perinatal birth defects in urban areas (312.65/10,000) was higher than that in rural areas (262.26/10 000), and the difference was statistically significant (χ²=119.974, P＜0.05). The incidence of birth defects in perinatal infants born to mothers under 20 years old was higher than that in other age groups. The top five major birth defects were congenital heart disease, polydactyly, external ear malformation, clubfoot, and hypospadias. Conclusion The incidence of perinatal birth defects in Changsha shows an overall downward trend , and the prevention and control measures for birth defects have shown effectiveness. To consolidate the achievements and control the incidence at a low level, the tertiary prevention of birth defects should be further strengthened.

Objective This study aims to investigate the structure and anti-angiogenic activity of homogeneous polysaccharides in Honeysuckle flowers,constructing the theoretical basis for its widespread application.Methods Homogeneous Honeysuckle polysaccharide LF-02-2 was obtained through water extraction,alcohol precipitation,anion exchange chromatography,and gel permeation chromatography.The structure of LF-02-2 was deduced through molecular weight determination,monosaccharide composition analysis,sugar residue linkage analysis,partial acid hydrolysis,and sugar aldonic acid reduction combined with NMR data.Additionally,in vitro tube formation experiments using human microvascular endothelial cells(HMEC-1)were conducted to assess its anti-angiogenic activity.Results Structural analysis of LF-02-2 revealed a homogeneous polysaccharide with a weight-average molecular weight of 74.1 kDa.The monosaccharide composition included rhamnose(Rha),galactose(Gal),galacturonic acid(GalA),and arabinose(Ara)in molar ratios of 10.43:14.94:6.66:67.97.The main chain consisted of 1,4-linked α-Galp A,1,2-linked α-Rhap,and 1,2,4-linked α-Rhap.Branches were connected to O-4 of 1,2,4-linked α-Rhap and included β-Galp with terminal connections and 1,4,6-linked β-Galp and α-Araf with terminal and 1,5-linked connections.Tube formation experiments demonstrated that LF-02-2 significantly inhibited tube formation in human microvascular endothelial cells(HMEC).Conclusion LF-02-2,an RG-I pectic polysaccharide from Honeysuckle flowers,exhibited significant anti-angiogenic activity,suggesting its potential for development as an anti-angiogenic drug.

Objective:To analyze the correlation between homocysteine (Hcy), ferritin and gestational anemia in advanced age pregnant women, and the effect on adverse pregnancy outcomes.Methods:The clinical data of 344 advanced age pregnant women in Handan City Maternal and Child Health Hospital from March 2021 to June 2022 were retrospectively analyzed. The adverse pregnancy outcomes were followed up and recorded. The pregnant women were divided into anemia group (114 cases) and control group (230 cases) according to the diagnostic criteria for anemia. The levels of Hcy and ferritin, etc. were compared between two groups, different degrees of anemia and different pregnancy outcomes. Pearson method was used to analyze the correlation between Hcy, ferritin and hemoglobin. Multivariate Logistic regression was used to analyze the independent risk factors of adverse pregnancy outcomes in advanced age pregnant women with gestational anemia.Results:The Hcy in anemia group was significantly higher than that in control group: (31.39 ± 3.34) mol/L vs. (9.28 ± 1.44) mol/L, the ferritin was significantly lower than that in control group: (69.81 ± 5.08) μg/L vs. (96.43 ± 7.52) μg/L, and there were statistical differences ( P<0.01). Among 114 advanced age pregnant women with gestational anemia, 64 cases were mild anemia (mild anemia group), 35 cases were moderate anemia (moderate anemia group), and 15 cases were severe anemia (severe anemia group). The levels of Hcy in the control group, mild anemia group, moderate anemia group and severe anemia group were gradually increased: (9.28 ± 1.44), (24.79 ± 3.25), (37.63 ± 5.51) and (45.01 ± 7.23) mol/L, the levels of ferritin were gradually decreased: (96.43 ± 7.52), (81.19 ± 5.14), (64.82 ± 4.47) and (32.96 ± 2.01) μg/L, and the difference between pairwise comparisons were statistically significant ( P<0.05). Pearson correlation analysis result showed that Hcy was negatively correlated with hemoglobin ( r = - 0.596, P<0.01), and ferritin was positively correlated with hemoglobin ( r = 0.685, P<0.01). Among 114 advanced age pregnant women with gestational anemia, 35 cases had adverse pregnancy outcomes, and 79 cases had normal pregnancy outcomes. The age, gestational reproductive tract infection rate and Hcy in advanced age pregnant women with adverse pregnancy outcomes were significantly higher than those in advanced age pregnant women with normal pregnancy outcomes: (41.17 ± 3.74) years old vs. (38.25 ± 4.28) years old, 28.57% (10/35) vs. 10.13% (8/79) and (49.56 ± 4.12) mol/L vs. (23.34 ± 2.63) mol/L, the ferritin was significantly lower than that in advanced age pregnant women with normal pregnancy outcomes: (38.36 ± 3.08) μg/L vs. (83.74 ± 6.25) μg/L, and the degree of gestational anemia was more serious than that in advanced age pregnant women with normal pregnancy outcomes, and there were statistical differences ( P<0.01 or <0.05). Multivariate Logistic regression analysis result showed that age, gestational reproductive tract infection, Hcy, ferritin and the degree of gestational anemia were the independent risk factors of adverse pregnancy outcomes in advanced age pregnant women with gestational anemia ( OR = 1.570, 1.758, 1.865, 1.556 and 1.652; 95% CI 1.154 to 2.136, 1.181 to 2.617, 1.223 to 2.842, 1.100 to 2.201 and 1.175 to 2.323; P<0.01). Conclusions:The level of Hcy in advanced age pregnant women with gestational anemia is relatively higher, and the level of ferritin is relatively lower. The ferritin and Hcy levels are risk factors for adverse pregnancy outcomes in advanced age pregnant women with gestational anemia, and may be involved in the occurrence and development of gestational anemia in advanced age pregnant women.

Objective: To understand the current situation of suicidal ideation among middle school students in Taiyuan City and its correlation with exposure to social ecological risk factors, so as to provide a reference basis for exploring the causes of suicidal ideation among middle and high school students and formulating effective preventive measures. Methods: A questionnaire survey was conducted among 2 639 middle school students in urban and rural areas of Taiyuan City by multistage stratified random cluster sampling, including general demography characteristics, social ecological risk factors and suicidal ideation. SPSS 26.0 software was used for Chi squared test and binary Logistic regression analysis. Results: The overall detection rate of suicidal ideation was 24.7 %. There were statistically significant differences in the detection rate of suicidal ideation among middle school students in different gender, grade, family residence, maternal education level, perceived family economic conditions, number of close friends, self-perceived academic burden ( χ 2=38.17, 13.44, 10.77, 8.15, 19.76, 18.95, 59.75, P <0.05). After adjusting the general demography characteristics, the binary Logistic regression showed that moderate and high risk in the individual, family and cultural dimension, and high risk in the school dimension of the social ecology were all positively correlated with suicidal ideation among middle school students ( OR=1.38, 2.28, 1.97, 3.28, 1.48, 2.15, 1.71, P <0.05). Conclusion The suicidal ideation among middle school students is related to individuals, families, and schools in the social ecological microsystem, as well as the cultural environment in the macro system. It is necessary to conduct intervention in suicidal ideation at the individual, family, and school levels, meanwhile, strengthening social and cultural construction to reduce the impact of adverse factors on the mental health among adolescents.

ObjectiveTo investigate the prevalence of overweight， obesity and fatty liver disease （FLD） in adult residents in a suburban area of Shanghai， and to explore the relationship between these conditions and eating out of home （EOH）. MethodsAdult residents from Zhongshan Street， Songjiang， Shanghai， were invited to report their frequency of EOH and undergo a physical examination using B-ultrasonography from May to September 2017. Binary logistic regression analyses were conducted to examine the relationship between EOH and conditions of overweight， obesity， and FLD. ResultsAmong the final sample size of 6 608 participants， the prevalence rates of overweight， obesity， and FLD were 41.65%， 14.71% and 38.29%， respectively. After adjusting for potential confounders， logistic analyses revealed that participants with an EOH frequency > once/week had a 1.44-fold higher prevalence of obesity （P=0.006）， a 1.35-fold higher prevalence of overweight/obesity （P=0.005）， and a 1.36-fold higher prevalence of FLD （P=0.008）. ConclusionThe prevalence of overweight， obesity， and FLD is relatively high in Songjiang， Shanghai. EOH may be a risk factor for these diseases， and residents are recommended to reduce the frequency of EOH.

Objective:To explore the application effect of comprehensive moxibustion therapy with Huolong Cupping in elderly patients with antibiotic-associated diarrhea.Methods:From June 2021 to February 2022, 60 elderly patients with antibiotic-associated diarrhea in the Second Affiliated Hospital of Zhejiang Chinese Medical University were selected as research objects, and divided into the observation group and the control group with 30 cases each by random number table method. The control group received Bifidobacterium treatment and routine nursing, and the observation group conducted comprehensive moxibustion therapy with Huolong Cupping on the basis of the control group. Seven days after intervention, total score of Traditional Chinese Medicine symptom, score of Gastrointestinal Quality of Life Index (GIQLI) were compared between the two groups.Results:Seven days after intervention, GIQLI score of the observation group was higher than that of the control group, and the difference was statistically significant ( P<0.05) ; total score of Traditional Chinese Medicine symptom of the observation group was lower than that of the control group, and the difference was statistically significant ( P<0.01) . Conclusions:Comprehensive moxibustion therapy with Huolong Cupping can improve clinical symptoms and gastrointestinal function in elderly patients with antibiotic-associated diarrhea, and improve their quality of life.

Objective:To evaluate the value of serum pepsinogen Ⅰ and Ⅱ combined with gastrin-17 in screening precancerous lesions of gastric cancer in physical examination population.Methods:Serum pepsinogen, gastrin-17 and Helicobacter pylori (Hp) antibody were detected in 18 354 physical examination people from July to December 2017 in Wenrong Hospital, Hengdian, Dongyang. The patients were divided into youth group (18 to 39 years old), middle-aged group (40 to 59 years old) and elderly group (≥60 years old) according to their ages. The correlation between the serological level of the above indexes and age was analyzed; according to the new ABC method, the test results were divided into groups A, B, C and D. The patients in group C and D were examined by gastroscopy. The differences of gastric mucosal atrophy or intestinal metaplasia and other precancerous lesions detected by gastroscopy in different age groups were compared.Results:Finally, 18 354 cases were enrolled, including 9 614 males and 8 740 females. With the increase of age, the proportion of group C and D increased gradually. In group C, 181 cases underwent gastroscopy, including 39 cases of atrophic gastritis, 29 cases of intestinal metaplasia and 3 cases of dysplasia/intraepithelial neoplasia, the detection rate of precancerous lesions was 39.23%; in group D, 94 cases underwent gastroscopy, including 22 cases of atrophic gastritis and 13 cases of intestinal metaplasia, the detection rate of precancerous lesions was 37.23%. The proportion of gastric precancerous lesions in group C and D was 29.63% in the young group, 69.70% in the middle-aged group and 71.58% in the old group, respectively. There was significant difference compared with the young group ( P<0.01); atypical hyperplasia occurred in 2.02% and 9.47% of the middle-aged group and the elderly group. Conclusions:The combined detection of serum pepsinogen Ⅰ and Ⅱ and gastrin-17 levels is of great value in the screening of precancerous lesions of gastric cancer; when this method used for early gastric cancer screening in healthy population, it is necessary to consider the influence of age for the risk stratification of gastric cancer.

Objective:To investigate the predictive value of blood routine and blood biochemical indicators for immunotherapy combined with chemotherapy-related interstitial pneumonia (IP) in patients with diffuse large B-cell lymphoma (DLBCL).Methods:The data of 151 newly-diagnosed DLBCL patients treated with rituximab combined with chemotherapy in the First Affiliated Hospital of Soochow University from December 2017 to October 2020 were retrospectively analyzed. According to whether IP occurred, the patients were divided into IP group and non-IP group. The patient's clinical data and baseline laboratory test results were collected. The differences in clinicopathological features and laboratory indicators between IP group and non-IP group were analyzed. In addition, the relationship between the variety of blood routine and blood biochemical indicators and the occurrence of IP was analyzed. The receiver operating characteristic (ROC) curve of the selected indicators to predict the occurrence of IP was drawn, and the predictive performance of each indicator was analyzed.Results:The incidence of IP was 9.3% (14/151) in DLBCL patients after receiving immunotherapy combined with chemotherapy. The lymphocyte count (LYM) in IP group at the first diagnosis was higher than that in non-IP group [1.60×10 9/L (1.40×10 9/L, 2.51×10 9/L) vs. 1.28×10 9/L (0.89×10 9/L, 1.78×10 9/L), U=-2.194, P=0.028], but there was no significant difference in the levels of platelet count, neutrophil count, monocyte count, lactate dehydrogenase (LDH), α-hydroxybutyrate dehydrogenase (α-HBDH), serum albumin (ALB) and the proportion of patients with elevated C-reactive protein (CRP) between the two groups (all P > 0.05). Compared with the laboratory indicators in non-IP group before the 4th cycle of treatment, LYM and ALB in IP group were significantly reduced at IP onset [0.72×10 9/L (0.46×10 9/L, 0.92×10 9/L) vs. 0.93×10 9/L (0.71×10 9/L, 1.15×10 9/L), 32.9 g/L (28.6 g/L, 34.9 g/L) vs. 40.3 g/L (36.1 g/L, 43.1 g/L)], but LDH and α-HBDH increased [332 U/L (255 U/L, 396 U/L) vs. 233 U/L (200 U/L, 286 U/L), 277 U/L (206 U/L, 315 U/L) vs. 189 U/L (159 U/L, 229 U/L)], and the differences were statistically significant (all P<0.05). The proportion of patients with elevated CRP in IP group was high than that in non-IP group [100.0% (14/14) vs. 56.9% (78/137), P=0.001]. The area under ROC curve of LYM, ALB, LDH and α-HBDH alone for predicting the occurrence of IP was 0.668, 0.820, 0.789 and 0.802. The best cut-off values of ALB, LDH and α-HBDH was 34.6 g/L, 241 U/L and 199 U/L. ALB had the highest sensitivity for predicting the occurrence of IP (81.8%). The areas under ROC curve of ALB+LDH, ALB+α-HBDH, LDH+α-HBDH, ALB+LDH+α-HBDH for predicting the occurrence of IP was 0.850, 0.844, 0.777 and 0.851, respectively. LDH+α-HBDH had the highest predictive sensitivity (92.9%), but the specificity was low (53.3%). The prediction sensitivity (both 78.6%) and specificity (both 86.1%) of ALB+LDH and ALB+LDH+α-HBDH were high. Conclusions:DLBCL patients are at risk of IP during immunotherapy combined with chemotherapy. The increased LYM at initial diagnosis is a risk factor for the occurrence of IP. The variety of LYM, ALB, LDH, α-HBDH and CRP during the treatment may be related to the occurrence of IP. Among them, ALB, LDH and α-HBDH have important predictive values for the occurrence of IP.
