Objective To explore whether or not the use of prophylactic antibiotics is required before inguinal hernia repair in metabolic syndrome (MS) patients.Methods According to the randomized double blind,prospective study,from 2010 July to 2012 December,186 MS patients underwent inguinal hernia repair operation were selected as the study objects.The control group(n =93) was given a one-time cefazolin 1.5g plus 0.9％ sodium chloride injection 20ml intravenous injection 30min before operation,the observation group(n =93) was given 0.9％ sodium chloride injection 20ml intravenous injection.Results The control group had 5 cases of infection,the observation group had 6 cases.There were no statistically significant differences in the normal body temperature of operation site infection,occurred between the two groups after operation (all P ＞ 0.05).But in the two groups,the probability of infection occurs of the patients with body mass index(WBI) more than 30 was higher that of the patients with 25 ≤WBI ≤ 30(17.24％ vs 1.56％,12.90％ vs 1.61％,x2 =4.69,4.87,all P ＜0.05),the probability of infection occurs of fasting blood glucose(FPG) more than 12.0mmol/L was higher than that of the patients with 6.1mmol/L≤FPG≤ 12.0mtol/L(15.30％ vs 1.64％,13.33％ vs 1.59％,x2 =4.81,5.13,all P＜0.05).Conclusion MS patients underwent tension-free repair of inguinal hernia don't need the use of antibiotics to prevent postoperative surgical site infection(SSI).But for the severe obesity,high blood sugar (FPG ＞ 12.0mmol/L) patients,the preoperation prophylactic antibiotics is necessary,and it can reduce the incidence of postoperative SSI.

This study introduces an innovative contour detection algorithm,PeakCET,designed for rapid and efficient analysis of natural product image fingerprints using comprehensive two-dimensional gas chromatogram(GC × GC).This method innovatively combines contour edge tracking with affinity propagation(AP)clustering for peak detection in GC × GC fingerprints,the first in this field.Contour edge tracking signif-icantly reduces false positives caused by"burr"signals,while AP clustering enhances detection accuracy in the face of false negatives.The efficacy of this approach is demonstrated using three medicinal products derived from Curcuma wenyujin.PeakCET not only performs contour detection but also employs inter-group peak matching and peak-volume percentage calculations to assess the compositional similarities and differences among various samples.Furthermore,this algorithm compares the GC × GC fingerprints of RadixlRhizoma Curcumae Wenyujin with those of products from different botanical origins.The findings reveal that genetic and geographical factors influence the accumulation of secondary metabolites in various plant tissues.Each sample exhibits unique characteristic components alongside common ones,and vari-ations in content may influence their therapeutic effectiveness.This research establishes a foundational data-set for the quality assessment of Curcuma products and paves the way for the application of computer vision techniques in two-dimensional(2D)fingerprint analysis of GC × GC data.

To explore screening tools for children with autism spectrum disorder (ASD), which are convenient for primary hospitals, it can provide basic data for formulating ASD prevention policies. This was a cross-sectional study by cluster sampling. Huyi District and Xincheng District were extracted for investigation in Xi′an City. From July 2021 to September 2022, all children aged from 3 months to 36 months who live in the two districts were subjected to primary screening. The child care physician used the routine screening tool "warning signs checklist for screening psychological, behavioral and developmental problems of children" and cartoon pictures of "early high-risk warning signs of autism", the children who were positive in the initial screening were referred to the district level maternal and child health hospital for re-screening, and those who were positive in the re-screening were referred to Xi ′an Children′s Hospital for diagnosis. The results showed that a total of 17 905 children aged from 3 months to 36 months were initially screened in the two districts, including 10 588 children aged from 18 months to 36 months, 50 children who were positive in the initial screening and 50 children who were re-screened. 23 children (18 boys and 5 girls) were diagnosed with ASD. The prevalence rate of ASD in children was 2.17‰ (95% confidence interval:1.29‰-3.06‰). 42 children were positive for "warning signs checklist" at the preliminary screening, and 19 were confirmed as ASD. 27 children were positive for "cartoon pictures" in the preliminary screening, and 23 were confirmed with ASD. The "cartoon pictures" in the preliminary screening and diagnosis of consistent rate was higher than the "warning signs checklist", two kinds of screening methods comparison were statistically significant difference in the odds of consistent (χ 2=11.01, P=0.001). In conclusion, relying on the three-level network of maternal and child health care, it is conducive to the whole process management of screening and diagnosis of children with ASD, and to guide the formulation of prevention policies. The cartoon pictures of "early high-risk warning signs of autism" can assist the identification of children with ASD based on the "warning signs checklist", which is simple, effective and suitable for promotion in the community health care.

Objective To analyze the quadrivalent influenza vaccine intention of 718 health care workers (HCWs) in the Pearl River Delta region from 2015 to 2017. Method In May 2018, 718 HCWs from the department related to the diagnosis and treatment of influenza in 17 hospitals (6 tertiary hospitals, 5 secondary hospitals and 6 primary hospitals) from Guangzhou, Jiangmen, Zhuhai and Dongguan were selected by using stratified sampling method. Questionnaire survey and face?to?face interview were used to collect the information of influenza vaccination, the intention of the quadrivalent influenza vaccine, the acceptance of free and required vaccination policies, and recommendations for increasing influenza vaccination intentions from 2015 to 2017. The multivariate logistic regression was used to analyze factors associated with the vaccination intention. Results A total of 718 HCWs were surveyed and 147 of them were interviewed face to face. Among them, the vaccination rate of primary hospitals [17.39%(40/230)] was higher than that of other hospitals (χ2=15.80, P<0.05). If the vaccine could be free, 84.82% (609/718) of HCWs would like to be vaccinated. The multivariate logistic regression showed that the factors, HCWs who were aged≥50 years (OR=3.44, 95%CI:1.43-8.28), worked in department of prevention and health care (OR=2.35, 95%CI : 1.16-4.75), learned about the quadrivalent influenza vaccine ( OR=2.94, 95%CI : 2.08-4.18), knowed that HCWs are priority ( OR=2.33, 95%CI : 1.56-3.48), and had a history of trivalent influenza vaccination from 2015 to 2017 (OR=4.70, 95%CI:3.08-7.15), were associated with the vaccination intention. Conclusion HCWs in the Pearl River Delta region had weak inclination of getting quadrivalent influenza vaccine. HCWs who were age (≥50 years old), worked in department of prevention and health care, learned about the quadrivalent influenza vaccine, knowed that HCWs are priority, and had a history of trivalent influenza vaccination from 2015 to 2017 were factors positively associated with the vaccination intention.

Objective To analyze serum characteristics and determine the reference range for thyroid function among healthy 11～16 year-old teenagers in Xi'an in order to offer a theoretical basis for clinical diagnosis and therapy.Methods A sum of 1 378 healthy 11～16 year-old teenagers who met the inclusion criteria from the First Affiliated Hospital of the Air Force Medical University(Xijing Hospital)between January 2020 and December 2022 were selected as research subjects,including 628 males and 750 females.They were divided into three groups based on age:Group 1:11～＜13 year-olds(433 cases),Group 2:13～＜15 year-olds(425 cases),and Group 3:15～≤16 year-olds(520 cases).Differences in serum thyroid function indices among different genders and age groups were analyzed,the reference ranges for these indices were established,and 99 healthy 11-16 year-old teenagers who met the inclusion criteria were chosen for verification.Results There were no significant differences between different genders in thyroid stimulating hormone[TSH,2.56(1.80,3.63)μIU/ml vs 2.43(1.68,3.48)μIU/ml]and total thyroxine[TT4,97.84(85.34,111.00)nmol/L vs 98.20(87.16,111.23)nmol/L],the differences were statistically significant(Z=-1.881,-0.638,all P＞0.05).Meanwhile,the differences in free thyroxine[FT4,16.93(15.49,18.60)pmol/L vs 16.26(14.80,17.83)pmol/L],free triiodothyronine[FT3,6.21(5.66,6.80)pmol/L vs 5.59(4.98,6.19)pmol/L],and total triiodothyronine[TT3,2.24(1.96,2.55)nmol/L vs 2.04(1.78,2.34)nmol/L]between different genders were significant(Z=-5.368,-11.994,-6.417 all P＜0.01).The differences in thyroid function indices were significant among different age groups(Z=10.649～261.003,all P＜0.05).The reference ranges for thyroid function indices across different age groups and genders were established,in which thyroid function indicators were verified to be within the established reference range by 99 samples.Conclusion Teenage hormone secretion varies greatly,and the secretion of thyroid hormones is influenced by various factors.Thus,the diagnosis and treatment of teenage thyroid diseases cannot fully rely on the reference ranges provided by adults or manufacturers.This study established the reference range of the thyroid function indices of 11～16 year-old teenagers in Xi'an,offering clinical doctors'diagnosis and treatment data support.

[Purpose]To analyze the fundamental data of cervical cancer screening,early diagno-sis,and treatment in Shenzhen from 2018 to 2022.[Methods]A retrospective analysis was con-ducted on data obtained from the Shenzhen Maternal and Child Health System's cervical cancer prevention and treatment information platform between January 2018 and December 2022,en-compassing a total of 2 419 037.Number of screening,detection rate,early diagnosis rate and treatment rate were calculated.[Results]The participation rate in the screening program exhibited a consistent annual increased from 2018 to 2022.Amongst the screened population,opportunistic screening accounted for 32.71％,government planned screening constituted 53.72％,while physi-cal examination-based screenings represented 15.83％.Notably,there were a total of 5 392 women diagnosed with CIN2 or above lesions;among them,there were also a total of 5 235 women diagnosed with CIN2+CIN3/carcinoma in situ+early-stage cancer.Furthermore,out of these cases identified through screening programs,a total of 4 996 women received appropriate treatment while only a small number(396)were lost to follow-up.The average detection rate for CIN2 and above lesions was found to be at an encouraging level of approximately 0.23％,with an impressive average early diagnosis rate reaching as high as 96.92％.Moreover,it was projected that from 2021 to 2022 the treatment rate exceeded 95％.[Conclusion]Since the start of HPV vaccination in China in 2017,the number of people participating in cervical cancer screening in Shenzhen has increased year by year,with the majority of government planned screening population.The early diagnosis rate and treatment rate have reached high levels after 2020.

OBJECTIVE To establish the quality standard of Triadica cochinchinensis and to perform the acute toxicity study. METHODS Appearance properties, powder microscopic identification, and thin-layer chromatography(TLC) identification were researched. The specific chromatogram was established by HPLC. The content of cadmium(Cd), lead(Pb), arsenic(As), copper(Cu), and mercury(Hg) was determined by inductively coupled plasma-mass spectrometry(ICP-MS). Acute toxicity was studied by maximum dose. RESULTS The outer skin of herbs was dark brown, and the inner surface was light yellow brown and fibrous. Besides, crystal sheath fiber was common, and calcium oxalate clusters arranges in rows. In the TLC diagram of the test product, the fluorescent spots of the same color were displayed at the corresponding position of the control product(scopoletin, isofraxidin). Five common peaks were calibrated in the characteristic map and the three characteristic peaks(scopoletin, isofraxidin, dimethylfraxetin) were recognized. The content of the measured heavy metal elements was lower than the national limit standard. The linear correlation coefficient was R2 > 0.999. The precision, stability, repetitive RSD were < 10%. The average recovery rate of the added sample was 80%−120%, and the RSD was < 10%. The maximum dose of the acute toxicity test was 184.09 g·kg−1. The 14 d internal body mass, food intake, organ-body ratios, the serum glutamic pyruvic transaminase, glutamic oxaloacetic transaminase, blood urea nitrogen, and creatinine were not significantly different by comparing with the normal controls. Therefore, no significant toxicity was observed. CONCLUSION The established standard can provide a reference for evaluating the quality of Triadica cochinchinensis. The heavy metal content of ten batches of medicinal materials is within the safe range. Acute toxicity test show that there is no obvious significant adverse teactions after oral administration, and the safe dose range is large, which can provide a reference for the subsequent development and utilization.

Objective:To assess the clinical effectiveness and safety of Omalizumab for treating pediatric allergic asthma in real world in China.Methods:The clinical data of children aged 6 to 11 years with allergic asthma who received Omalizumab treatment in 17 hospitals in China between July 6, 2018 and September 30, 2020 were retrospectively analyzed.Such information as the demographic characteristics, allergic history, family history, total immunoglobulin E (IgE) levels, specific IgE levels, skin prick test, exhaled nitric oxide (FeNO) levels, eosinophil (EOS) counts, and comorbidities at baseline were collected.Descriptive analysis of the Omalizumab treatment mode was made, and the difference in the first dose, injection frequency and course of treatment between the Omalizumab treatment mode and the mode recommended in the instruction was investigated.Global Evaluation of Treatment Effectiveness (GETE) analysis was made after Omalizumab treatment.The moderate-to-severe asthma exacerbation rate, inhaled corticosteroid (ICS) dose, lung functions were compared before and after Omalizumab treatment.Changes in the Childhood Asthma Control Test (C-ACT) and Pediatric Asthma Quality of Life Questionnaire (PAQLQ) results from baseline to 4, 8, 12, 16, 24, and 52 weeks after Omalizumab treatment were studied.The commodity improvement was assessed.The adverse event (AE) and serious adverse event (SAE) were analyzed for the evaluation of Omalizumab treatment safety.The difference in the annual rate of moderate-to-severe asthma exacerbation and ICS reduction was investigated by using t test.The significance level was set to 0.05.Other parameters were all subject to descriptive analysis.A total of 200 allergic asthma patients were enrolled, including 75.5% ( n=151) males and 24.5% ( n=49) females.The patients aged (8.20±1.81) years. Results:The median total IgE level of the 200 patients was 513.5 (24.4-11 600.0) IU/mL.Their median treatment time with Omalizumab was 112 (1-666) days.Their first dose of Omalizumab was 300 (150-600) mg.Of the 200 cases, 114 cases (57.0%) followed the first Omalizumab dosage recommended in the instruction.After 4-6 months of Omalizumab treatment, 88.5% of the patients enrolled ( n=117) responded to Omalizumab.After 4 weeks of treatment with Omalizumab, asthma was well-controlled, with an increased C-ACT score [from (22.70±3.70) points to (18.90±3.74) points at baseline]. Four-six months after Omalizumab administration, the annual rate of moderate-to-severe asthma exacerbation had a reduction of (2.00±5.68) per patient year( t=4.702 5, P<0.001), the median ICS daily dose was lowered [0 (0-240) μg vs. 160 (50-4 000) μg at baseline] ( P<0.001), the PAQLQ score was improved [(154.90±8.57) points vs. (122.80±27.15) points at baseline], and the forced expiratory volume in one second % predicted (FEV 1%pred) was increased [(92.80±10.50)% vs. (89.70±18.17)% at baseline]. In patients with available evaluations for comorbidities, including allergic rhinitis, atopic dermatitis or eczema, urticaria, allergic conjunctivitis and sinusitis, 92.8%-100.0% showed improved symptoms.A total of 124 AE were reported in 58 (29.0%) of the 200 patients, and the annual incidence was 0(0-15.1) per patient year.In 53 patients who suffered AE, 44 patients (83.0%) and 9 patients (17.0%) reported mild and moderate AE, respectively.No severe AE were observed in patients.The annual incidence of SAE was 0(0-1.9) per patient year.Most common drug-related AE were abdominal pain (2 patients, 1.0%) and fever (2 patients, 1.0%). No patient withdrew Omalizumab due to AE. Conclusions:Omalizumab shows good effectiveness and safety for the treatment of asthma in children.It can reduce the moderate-to-severe asthma exacerbation rate, reduce the ICS dose, improve asthma control levels, and improve lung functions and quality of life of patients.
