Results The higher midwife nurses in experiment group were the scores of (3.78±0.32) and (2.82±0.26) in control group with statistical significance between two groups (t=8.173,P<0.01).Conclusions The teaching methods of PBL,CBL and LBL can improve clinical internship effects in higher midwife nurses effectively and improve clinical teaching quality.

Objective:To observe the clinical efficacy of a new type of "firebreak" drainage with skin preservation in the treatment of Fournier's gangrene.Methods:This technique is suitable for patients with perianal necrotizing fasciitis who can tolerate surgery without large area of skin blackness and necrosis. Procedure and key points: (1) The dividing line between inflammatory tissue and normal tissue was determined according to imaging examination and intraoperative exploration; (2) The abscess cavity was cut along the most obvious part of the abscess fluctuation, with a long diameter of 3~4 cm and a short diameter of 1~2 cm; (3) Necrotic tissue was discreetly separated and removed from the main incision to the outer edge of the infection. A fusiform incision was made every 3 to 5 cm, with a long diameter of 2 to 3 cm and a short diameter of 1 cm, and discreetly separated until the normal tissue, and a hose was hung between the adjacent incisions for drainage. (4) Each adjacent edge cut between the stealth separation and hanging hose drainage, forming a "firebreak"; (5) Rinse the wound repeatedly; (6) If the infection invades the rectum, colostomy is performed as required. The case data of 11 patients with perianal necrotizing fasciitis admitted to the Second Affiliated Hospital of Nanjing University of Chinese Medicine from July 2019 to February 2023 were retrospectively analyzed. All patients were treated with emergency surgical debridement by "firebreak" drainage with skin preservation.Results:All 11 cases were cured with 100%. One case underwent multiple operations. The hospitalization time was 11-46 days, with an average of 22 days. The wound healing time was 28-75 days, with an average of 43 days. Except for 1 patient with trauma, all the other patients had no significant anal function injury after surgery. All the 11 patients recovered and were discharged from hospital with a median follow-up of 136 (115-413) days.Conclusions:The "firebreak" drainage based on skin preservation has the advantages of less trauma and faster recovery, and do not cause obvious anal function damage.

Objective: To understand the relationship between medication during pregnancy and single live preterm birth of infant in women of childbearing age in Shaanxi province. Methods: A cross-sectional design was used in this study and stratified multistage random sampling method was used. A questionnaire survey was conducted in the childbearing-aged women selected through multi stage stratified random sampling in Shaanxi during 2010 to 2013. Qualitative datum was described by percentage and measurement datum was described by mean±standard deviation. Logistic regression analysis was done to evaluate the relationship between medication during pregnancy and preterm birth of infant. Results: The overall incidence rate of premature birth was 2.7% in Shaanxi. Among the 28 841 mothers participating in this study, the proportion of medication use at any time during pregnancy was 15.8%, and the most commonly used drug was cold medicine (5.9%). After adjusting all confounding factors, the multivariable logistic regression analysis results showed that taking hormone medicine (OR=2.23, 95%CI: 1.19-4.18), antihypertensive medicine (OR=7.74, 95%CI: 4.28-13.95) and other medicines (OR=2.15, 95%CI: 1.60-2.89) during early pregnancy were the risk factors for preterm delivery, the risk was 2.23 times, 7.74 times and 2.15 times higher compared with those taking no these medicines. Conclusion Using hormone medicine, antihypertensive medicine and other medicines during pregnancy increased the risk for preterm delivery in women of childbearing age in Shaanxi.

Objective: To investigate the relationship between maternal disease in early pregnancy of women of childbearing age and congenital heart disease of neonates. Methods: A cross-sectional design was used in this study and stratified multistage random sampling method was used. A questionnaire survey was conducted in the childbearing-aged women during 2010-2013 in Shaanxi province. Propensity score (PS) matched (1∶1) analysis was used to match participants with diseases to those without disease in early pregnancy. Through the control of the confounders step by step, a logistic regression model was established to evaluate the ORs of congenital heart disease according to the independent variable of maternal disease. Results: A total of 28 680 pairs of mothers and infants were included in this study, the proportion of the women with disease in early pregnancy was 20.25% (5 807). After PS matching, 5 436 pairs were matched. After adjusting all confounding factors, the multivariable logistic regression analysis results showed that maternal disease (OR=1.86, 95%CI: 1.23-2.81), especially cold (OR=2.19, 95%CI: 1.46-3.28), gynecological disease (OR=4.74, 95%CI: 2.03-11.09) and diabetes (OR=14.00, 95%CI: 1.64-119.21), in early pregnancy were the risk factors for congenital heart disease of neonate. Conclusion In women of childbearing age, disease in early pregnancy, especially cold, gynecological disease and diabetes, can increase the risk of congenital heart disease in neonates.

Background: Microsporum canis is a zoonotic disease that can cause dermatophytosis in animals and humans. Objectives: In clinical practice, ketoconazole (KTZ) and other imidazole drugs are commonly used to treat M. canis infection, but its molecular mechanism is not completely understood.The antifungal mechanism of KTZ needs to be studied in detail. Methods: In this study, one strain of fungi was isolated from a canine suffering with clinical dermatosis and confirmed as M. canis by morphological observation and sequencing analysis.The clinically isolated M. canis was treated with KTZ and transcriptome sequencing was performed to identify differentially expressed genes in M. canis exposed to KTZ compared with those unexposed thereto. Results: At half-inhibitory concentration (½MIC), compared with the control group, 453 genes were significantly up-regulated and 326 genes were significantly down-regulated (p < 0.05). Quantitative reverse transcription polymerase chain reaction analysis verified the transcriptome results of RNA sequencing. Gene ontology enrichment analysis and Kyoto Encyclopedia of Genes and Genomes enrichment analysis revealed that the 3 pathways of RNA polymerase, steroid biosynthesis, and ribosome biogenesis in eukaryotes are closely related to the antifungal mechanism of KTZ. Conclusions The results indicated that KTZ may change cell membrane permeability, destroy the cell wall, and inhibit mitosis and transcriptional regulation through CYP51, SQL, ERG6, ATM, ABCB1, SC, KER33, RPA1, and RNP genes in the 3 pathways. This study provides a new theoretical basis for the effective control of M. canis infection and the effect of KTZ on fungi.

OBJECTIVETo investigate the correlation between smoking status and carotid plaque in rural population residing in Eastern part of China.

METHODSBetween July and September of 2013, an epidemiological survey was carried out in residents aged 40 or above men who were enrolled randomly in rural areas of Anqing, Anhui province and Lianyungang, Jiangsu province. The data on epidemiological characteristics including smoking status, physical examination were collected using standardized protocol, and carotid ultrasonography was applied to examine the incidence of carotid plaque among never smokers, former smokers and current smokers. Logistic regress analysis was performed to determine the effect of smoking on carotid plaque.

RESULTSIn the study, a total of 625 male participants were included in the study. 51.4% (321 cases) were current smokers, 21.3% (133 cases) were former smokers, and 27.4% (171 cases) were never smokers. 32.0% (200/625) had carotid plaque. The incidence of carotid plaques was significantly higher in current smokers (35.2%, 113/321) than that in never smokers(23.4%,40/171) (χ(2) = 7.26, P = 0.007) and the incidence in former smokers (35.3%, 47/133) was also higher than that in never smokers (23.4%, 40/171) (χ(2) = 5.23, P = 0.022). Multiple logistic regression analysis showed that current cigarette smoking is significantly associated with the increased risk of carotid plaque (OR = 1.84, 95% CI: 1.13-2.98, P = 0.014) in comparison with never smokers, and there was an interaction between current smoking and age in association with carotid plaque. Compared with the young (≤60 years old) and never smoking group (8%, 3/40), prevalence of carotid plaque among the elderly (>70 years old) and smoking group (55%, 31/56) was significantly higher (OR = 8.06, 95% CI: 2.07-31.45) after adjusting for age, systolic blood pressure, diastolic blood pressure, blood glucose, total cholesterol, triglyceride high-density lipoprotein, body mass index, drinking and regional differences.

CONCLUSIONIt found that cigarette smoking was associated with increased risk of carotid plaque in rural elderly population residing in Eastern part of China.

Objective:This study explored the association between antenatal calcium supplementation in the childbearing aged women and risk of small for gestational age infant (SGA) among singleton in Shaanxi province,China.Methods:Multi-stage random cluster sampling method was employed to collect information about pregnant women, who were pregnant and had definite outcomes, and their infants, from 30 districts (counties) in 2010 to 2013. Information was collected by face-to-face questionnaire survey. Generalized linear mixed models were employed after adjusting covariates. Dependent variable was whether single-birth neonate was SGA, and independent variable was calcium supplementation of childbearing aged women in different pregnant periods.Results:A total of 28 357 childbearing aged women was recruited in this study. The age of these women was (28.08±4.74) years old, of which, 79.28% were rural residents and 60.90% had calcium supplementation intake. There was a number of 12 810 female in singleton neonates. The neonatal birth weight and gestational age were (3.27±0.16) kg and (277.44±8.80) day, respectively. The prevalence of SGA was 11.35% in total, and 10.48% in mothers with maternal calcium supplementation and 12.70% in mothers without maternal calcium supplementation in whole antenatal period. There were statistically significant differences seen in antenatal calcium supplementation within the subgroups of maternal age (whether the mother was an advanced maternal woman), residential area, maternal occupation, maternal parity, maternal education level, and household incomes ( P<0.05). After adjusting these covariates, the risk of SGA among childbearing aged women with antenatal calcium supplementation showed 16% decreased risk ( OR=0.84, 95% CI: 0.77-0.92). Further analysis of the different antenatal periods showed that calcium supplementation during the second and third trimester had a statistically significant difference in reducing the risk of neonatal SGA ( P<0.05). Besides, subgroup analysis showed that there was a statistically significant difference between the perinatal calcium supplementation and the single-born neonates with SGA Significance ( P<0.05) in non-advanced women, those who had a low education level and moderate household economic status groups. Conclusion:The risk reduction of SGA among singleton neonates is related to calcium supplementation during antenatal period in Shaanxi province.

Objective:To investigate the relationship between triglyceride glucose index (TyG) and body inflammation.Methods:The data were obtained from a baseline survey in population in Xi'an in natural population cohort study in northwest China established in 2018-2019. Based on TG and FPG, TyG/TyG-BMI was constructed to reflect insulin resistance (IR) in the body, and systemic immune-inflammation index (SII) reflecting inflammation in the body was constructed using neutrophil, lymphocyte, and platelet counts. A logistic regression model was used to explore the relationship between the TyG and the SII.Results:A total of 11 491 subjects were included in the analysis. After adjusting for covariates, each unit increase in the TyG increased the risk of high SII by 21% ( OR=1.21, 95% CI:1.12-1.30). The risk of high SII in the group with the TyG in Q4 was 1.34 times higher than that in the group Q1 ( OR=1.34, 95% CI:1.18-1.52). Both sensitivity analysis and subgroup analysis further confirmed the stability of the association between the TyG and the SII. In the population with a BMI ranging from 18.5 to 23.9 kg/m 2, for every unit increase in the TyG as a continuous variable, the risk for high SII increased by 31% ( OR=1.31, 95% CI:1.18-1.45). As a categorical variable, the risk for high SII in the Q4 group was 1.52 times higher than that in the Q1 group ( OR=1.52, 95% CI:1.27-1.83). In a population with BMIs ranging from 24.0 to 27.9 kg/m 2, for every unit increase in the TyG as a continuous variable, the risk for high SII increased by 20% ( OR=1.20, 95% CI:1.07-1.35), and there was no significant difference when it was a categorical variable. Conclusions:The increase in IR is closely related to the development of inflammation in the body, and BMI may regulate their relationship. Early prevention of elevated IR levels before overweight or obesity may have a positive effect on the control of inflammation in the body.
