Background Staff in tertiary hospitals are a high-risk group for occupational burnout. Timely identification and precise intervention are crucial for improving healthcare service quality. However, comparative studies on perceived stress and occupational burnout among hospital staff in different positions are lacking. Objective To describe the status of perceived stress and occupational burnout among hospital staff in different positions and compare the differences, explore the relationship between perceived stress and occupational burnout, and identify the influencing factors of occupational burnout. Methods In May 2022, 1526 hospital staff members were selected by convenience sampling from six tertiary hospitals in Guangzhou. Data were collected using a general information questionnaire, the Chinese Perceived Stress Scale (CPSS), and the Maslach Burnout Inventory-Human Services Survey (MBI-HSS) to assess demographic characteristics, perceived stress, and occupational burnout. Chi-square test, one-way ANOVA, and Kruskal-Wallis H test were used to compare differences in perceived stress and occupational burnout among staff in different positions. Pearson correlation analysis was used to explore possible correlation between perceived stress and occupational burnout. Multiple linear regression was conducted to identify influencing factors of occupational burnout. Results A total of 1388 valid questionnaires were collected, with an effective response rate of 90.96%. Among them, 437 nurses (57.0%), 273 physicians (58.6%), 24 pharmacists (57.1%), and 62 administrators (54.9%) reported positive perceived health risk stress (P=0.892). Additionally, 392 nurses (51.1%), 213 physicians (45.7%), 19 pharmacists (45.2%), and 53 administrators (46.9%) reported positive occupational burnout (P=0.005). Perceived stress was positively correlated with occupational burnout among nurses, physicians, pharmacists, and administrators (r=0.5973, 0.5687, 0.5464, and 0.5276, respectively; P＜0.01). The multiple linear regression identified perceived stress (b=1.4587, P＜0.001), job satisfaction (b=−7.4195, P＜0.001), self-rated health (b=−2.0428, P＜0.001), working years (b=−0.1135, P=0.016), and being a nurse (compared with an administrators) (b=3.2435, P=0.045) as significant factors for occupational burnout (P<0.001). Conclusion Perceived health risk stress and occupational burnout are common among hospital staff, with nurses experiencing significantly higher levels of occupational burnout compared to other positions. Hospital managers should pay more attention to staff with higher perceived stress, lower job satisfaction, poorer self-rated health, and shorter working years, particularly nurses.

OBJECTIVES: To investigate the effect of Ching Shum Pills (CSP) for alleviating non-alcoholic fatty liver disease (NAFLD) and the underlying mechanism. METHODS: In a mouse model of NAFLD, the therapeutic effect of CSP was evaluated by measuring serum glucose, lipid profiles (TC, TG, LDL-C, HDL-C), and hepatic function markers. Network pharmacology was employed to identify active compounds in CSP and their targets using TCMSP, HERB, SwissTargetPrediction, GeneCards, OMIM, and DisGeNET. Protein-protein interaction (PPI) networks, Gene Ontology (GO), and KEGG pathway analyses were conducted. Molecular docking (AutoDock Vina) was used to assess the compound-target binding affinities. Quantitative real-time PCR (qRT-PCR) was used to validate the mRNA expressions of the core genes in the liver tissue of the mouse models. RESULTS: In the mouse model of NAFLD, treatment with CSP significantly reduced body weight gain and serum TG levels of the mice, and high-dose CSP treatment resulted in obvious reduction of ALT levels and hepatic fat accumulation. Network pharmacology analysis identified quercetin and 2-monolinolenin as the key bioactives in CSP, which target TNF, AKT1, IL6, TP53, and ALB. Docking simulations suggested strong binding between the two core compounds and their target proteins. The results of qRT-PCR showed that high-fat diet induced significant downregulation of Tp53, Cpt1, and Ppara expressions in mice, which was effectively reversed by CSP treatment. CONCLUSIONS CSP can improve lipid metabolism disorders in NAFLD mice through a regulatory mechanism involving multiple targets and pathways to reduce liver fat accumulation and protect liver function. The key components in CSP such as quercetin and linolenic acid monoacylglycerol may participate in the regulation of such metabolic processes as fatty acid oxidation by targeting TP53.

Background::Although the treatment of peripheral T-cell lymphoma (PTCL) has undergone advancements during the past several years, the response rate and long-term effects with respect to patients with PTCL remain unsatisfactory—particularly for relapsed or refractory (R/R) patients. This phase II trial was designed to explore the efficacy and safety of an all-oral regimen of chidamide plus prednisone, cyclophosphamide, and thalidomide (CPCT) for R/R PTCL patients who could not tolerate the standard chemotherapy for a variety of reasons.Methods::We conducted a multicenter phase II clinical trial in which we combined chidamide (30 mg twice weekly) with prednisone (20 mg daily after breakfast), cyclophosphamide (50 mg daily after lunch), and thalidomide (100 mg daily at bedtime) (the CPCT regimen) for a total of fewer than 12 cycles as an induction-combined treatment period, and then applied chidamide as single-drug maintenance. Forty-five patients were ultimately enrolled from August 2016 to April 2021 with respect to Chinese patients at nine centers. Our primary objective was to assess the overall response rate (ORR) after the treatment with CPCT.Results::Of the 45 enrolled patients, the optimal ORR and complete response (CR)/CR unconfirmed (CRu) were 71.1% (32/45) and 28.9% (13/45), respectively, and after a median follow-up period of 56 months, the median progression-free survival (PFS) and overall survival (OS) were 8.5 months and 17.2 months, respectively. The five-year PFS and OS rates were 21.2% (95% confidence interval [CI], 7.9-34.5%) and 43.8% (95% CI, 28.3-59.3%), respectively. The most common adverse event was neutropenia (20/45, 44.4%), but we observed no treatment-related death.Conclusion::The all-oral CPCT regimen was an effective and safe regimen for R/R PTCL patients who could not tolerate standard chemotherapy for various reasons.Trial Registration::ClinicalTrials.gov, NCT02879526.

Objective:To investigate the iodine nutrition level and thyroid function status of pregnant women in Hubei Province.Methods:According to the requirements of "the National Iodine Deficiency Disorders Monitoring Program (2016 Edition)", in 2020, using a cross-sectional survey method, two mountainous counties and two plain areas in Hubei Province were divided into five districts: east, west, south, north, and central. One township (street) was selected from each district, and 20 pregnant women were selected from each township (street) as survey subjects. Urine iodine content and thyroid function indicators [serum free triiodothyronine (FT 3), free thyroxine (FT 4), thyroid-stimulating hormone (TSH), thyroid peroxidase antibody (TPOAb), thyroglobulin antibody (TgAb)] were tested. Abnormal thyroid function rate and antibody positive rate were analyzed, and correlation analysis of thyroid function indicators was conducted (Spearman method). Results:A total of 321 pregnant women were included, including 43, 114, and 164 in early, middle, and late pregnancy, respectively; The median urinary iodine was 164.80 μg/L. The median serum FT 3, FT 4, TSH, TPOAb, TgAb levels were 4.10, 12.83 pmol/L, 1.85 mU/L, 15.84 and 13.35 U/ml, respectively. There were statistically significant differences in FT 3, FT 4, and TSH levels among different trimesters ( P < 0.05). According to Spearman's correlation analysis, FT 3 in early stage of pregnancy was negatively correlated with TSH and TPOAb levels ( r = - 0.46, - 0.33, P < 0.05), while TSH was positively correlated with TPOAb level ( r = 0.33, P = 0.032); there was a positive correlation between FT 4 and TgAb levels in middle stage of pregnancy ( r = 0.21, P = 0.032); there was a negative correlation between FT 3 and TPOAb levels in late stage of pregnancy ( r = - 0.19, P = 0.017); FT 3 and FT 4, TPOAb and TgAb levels were positively correlated throughout pregnancy ( P < 0.05). There was no correlation between urinary iodine content and thyroid function indicators ( P > 0.05). The total abnormal rate of thyroid function was 7.79% (25/321), with 16.28% (7/43), 5.26% (6/114), and 7.32% (12/164) in early, middle, and late pregnancy, respectively. There was no statistically significant difference in the abnormal rate of thyroid function among different pregnancy periods (χ 2 = 4.83, P = 0.097). The detection rates of hypothyroxinemia, hypothyroidism, subclinical hypothyroidism, hyperthyroidism, and subclinical hyperthyroidism were 4.36% (14/321), 0.31% (1/321), 2.49% (8/321), 0.31% (1/321), and 0.31% (1/321), respectively. The positive detection rate of autospecific antibodies was 10.28% (33/321), with a TPOAb positive detection rate of 9.97% (32/321) and a TgAb positive detection rate of 5.30% (17/321). Conclusions:The iodine nutrition level of pregnant women in Hubei Province is at a suitable level, and the rates of abnormal thyroid function and thyroid autospecific antibody positive are relatively low. It is necessary to continuously monitor the iodine nutrition and thyroid function indexes of pregnant women, strengthen health education on the hazards of iodine deficiency during pregnancy, and minimize the harm to maternal and infant health caused by iodine deficiency.

AIM: To observe and compare the clinical efficacy and safety of remimazolam and propofol alone and in combination in endoscopic retrograde cholangiopancreatography (ERCP) anesthesia. METHODS: A total of 120 patients undergoing elective ERCP were divided into the propofol group (P group), the remimazolam group (R group), and the remimazolam combined with propofol group (RP group) according to a random number table, with 40 patients in each group, and the three groups completed anesthesia according to the designated drug regimen (propofol in group P; remimazolam in group R; and remimazolam combined with propofol in group RP). General information, operation time and awakening time of the patients in the three groups were compared, as well as oxygen saturation (SpO

Objective:To study the influence of different feeding patterns on mother-to-child transmission (MTCT) of hepatitis B virus (HBV) in pregnant women with high viral loads who received antiviral medication during pregnancy to the day of delivery.Methods:This prospective cohort study was conducted in Beijing You'an Hospital. From January 1, 2019, to March 31, 2020, and 574 pregnant women with positive hepatitis B surface antigen (HBsAg) and HBV DNA>2×10 5 IU/ml were enrolled. All participants received tenofovir, telbivudine, lamivudine, or propofol tenofovir from 24-28 weeks of gestation and discontinued on the day of delivery, and their neonates were postnatally given routine passive-active immunoprophylaxis. Based on the feeding patterns, the subjects were divided into three groups: breastfeeding ( n=257), bottle-feeding ( n=241) and mixed feeding groups ( n=76). The follow-up data were obtained from liver functions and HBV DNA level of the mothers at 6-8 weeks postpartum and HBV serological markers of infants at 7-12 months. One-way ANOVA, Student-Newman-Keuls, Chi-square test or Fisher exact test, and repeated measures ANOVA were used to analyze the data. Results:The average maternal HBV DNA levels before antiviral treatment did not differ significantly between the three groups [(7.90±0.67), (7.82±0.70), (7.83±0.70) log 10 IU/ml, F=0.912, P>0.05]. HBV DNA level before delivery in the mixed feeding group was slightly lower than that in the breastfeeding and bottle-feeding group [(3.87 ±1.08) vs (4.21±1.17) and (4.30±1.28) log 10 IU/ml, q= 3.052 and 3.831, both P<0.05], while the comparison between the latter two groups showed no significant differences ( P>0.05). After delivery, HBV DNA level in the bottle-feeding group was slightly lower than that in the breastfeeding group [(7.42±0.93) vs (7.69±0.90) log 10 IU/ml, q=4.583, P<0.05]. Among 580 infants (including six pairs of twins), only one bottle-fed infant (0.4%, 1/243) was infected with HBV through MTCT, and none in the breastfeeding or mixed feeding group ( P=0.553). Conclusions:For pregnant women with high viral loads of HBV who have received antiviral medication during pregnancy, although HBV DNA level will rebound after discontinuation upon delivery, breastfeeding is recommended considering it does not increase the risk of MTCT.

Objective:To evaluate the intrauterine transmission of syphilis in Nantong City, Jiangsu Province from 2012 to 2019, after the introduction of a nationwide policy for preventing intrauterine transmission of syphilis in China in 2011.Methods:This study enrolled all live birth deliveries ( n=455 561) in Nantong from January 2012 to December 2019. The screening, infection rates, anti-syphilis treatment, intrauterine transmission of syphilis, and outcomes of infants with congenital syphilis were retrospectively analyzed using χ 2 test for trend, adjusted χ 2 test, or Fisher's exact test. Results:Except for three women, the remaining 455 558 subjects were all screened for syphilis antibody with a total screening rate of nearly 100%, among which prenatal screening accounted for 96.4% (439 125/455 561) and intrapartum screening for 3.6% (16 433/455 561). In total, 796 (0.17%) women were diagnosed with syphilis during pregnancy, and the prevalence increased from 0.13% (85/64 229) in 2012 to 0.24% (110/45 517) in 2019 (χ 2trend=48.985, P<0.001). The prevalence among women underwent intrapartum screening was significantly higher than those underwent prenatal screening [0.50% (82/16 433) vs 0.16% (714/439 125), χ 2=102.769, P<0.001]. Out of the women with syphilis, 716 (89.9%) received anti-syphilis therapy with 695 cases using penicillin, 16 cases using ceftriaxone and five using erythromycin/azithromycin, while the remaining 80 (10.1%) did not. Intrauterine transmission of syphilis occurred in 14 infants with a transmission rate of 1.8% (14/796). The reported rate of congenital syphilis in all live infants was 0.03‰ (14/460 552). The intrauterine transmission rate in women receiving treatment during pregnancy was significantly lower than that in the untreated women [0.4% (3/716) vs 13.8% (11/80), χ2=66.499, P<0.001]. For the untreated women, the intrauterine transmission rate increased with the rising titers of non-specific syphilis antibody ( χ2trend=5.338, P=0.021). Among infants with congenital syphilis, no obvious adverse outcomes occurred in three infants born to treated mothers, whereas the rates of preterm birth and neonatal death were 7/11 and 2/11 in those born to untreated mothers. Conclusions:Since the implementation of the policy against intrauterine transmission of syphilis, the reported rate of congenital syphilis is 3/100 000 live-birth in Nantong City, reaching the national target of below 15/100 000. Screening and treatment in the first trimester are critical for preventing intrauterine transmission of syphilis. Increased prenatal syphilis screening rate can help further reduction of the intrauterine transmission of syphilis.

As a kind of skills clinical medical students must master, the basic teaching of operative surgery is relatively backward in teaching mode and means, thus negatively affecting the teaching effect. The virtual reality is applied to the basic teaching of operative surgery, and the pre-designed course contents are presented in a situational way, so that students can experience the immersive learning style. It changes the classroom roles, gives full play to the advantages of virtual reality, and makes up the disadvantage of traditional education mode, finally improving the training effect.

Objective To assess the efficacy of immunoprophylaxis against mother-to-infant transmission of hepatitis B virus (HBV) in a real-world setting since the implementation of charge-free hepatitis B immunoglobulin (HBIG) and hepatitis B vaccine in China. Methods The screening rate and the prevalence of hepatitis B surface antigen (HBsAg) in 61 790 puerperants, and the administration of combined immunoprophylaxis in infants of HBsAg-positive mothers in Rugao City of Jiangsu Province from July 1, 2011 to June 30, 2016 were retrospectively analyzed. HBV infection status of infants born to HBV infected mothers was followed up after 7 months of age. HBsAg-positive infants and their mothers were followed up again for HBV markers in April 2018. Fisher's exact test and Cochran-Armitage trend test were used to statistically analyze the differences between groups and various years, respectively. Results All 61 790 puerperants were screened for HBsAg and the prenatal screen rate was 98.6% (60 937/61 790) with an increasing trend over time (χ2trend=750.908, P<0.001). HBsAg-positive puerperants accounted for 5.5% (3 397/61 790) with a decreasing trend over time (χ2trend=32.667, P<0.001). In total, 778 offspring (399 boys and 379 girls) of 759 HBsAg-positive mothers were followed up at (13.7±6.9) months of age, among which 751 (96.5%) were administered and 25 (3.2%) were probably administered standard combined immunoprophylaxis after birth, and the rest two (0.3%) were not. Fourteen infants (1.8%) were HBsAg positive and all born to mothers with positive hepatitis B e antigen (HBeAg). None of the 538 infants born to HBeAg-negative mothers was HBsAg-positive. HBsAg-positive rate in infants born since 2013 was lower than those in 2011 and 2012 (χ2trend=13.352, P=0.000 3). Eleven HBsAg-positive mothers and their children were followed up again 4–5 years later in April 2018. HBV DNA levels of all mothers were within the range of (7.34–28.2)×107 IU/ml except one case of spontaneous HBeAg seroconversion. One out of the 11 infected children also had HBeAg seroconversion. Phylogenetic analysis of HBV S gene showed that the 11 pairs of mothers and children were all infected with HBV of genotype C. Conclusions The implementation of charge-free HBIG and hepatitis B vaccine for newborns achieves fruitful results in Rugao city as the mother-to-infant transmission of HBV in the real-world had been further reduced to a similar level reported in literature survey.

Objective To analyze the status of iodine nutrition after implementing new standard of iodized salt in Hubei Province,and to evaluate the effectiveness of prevention and control measures.Methods In 2016,in 103 counties (cities,districts) of Hubei Province,the townships (streets) under the jurisdiction of each county (city,district) were divided into five regions:east,south,west,north,and middle.One township (street) was selected from each region,and one primary school was selected from each township (street).From each primary school 40 children aged 8-10 (half males half females) were selected to collect salt samples from their households.Twenty pregnant women from townships (streets) near the selected schools were chosen to collect edible salt samples from their households.According to the method of population proportionate sampling (PPS),35 counties (cities,districts) were chosen from 103 counties (cities,districts).Thyroid volume of children aged 8-10 was examined,and urinary iodine of children and pregnant women were tested.Iodine nutrition criteria:the median urinary iodine of children ＜ 100 μg/L is iodine deficiency,100-＜ 200 μg/L is iodine appropriate,200-＜ 300 μg/L is iodine overdose,≥300 μg/L is iodine excess;pregnant women urinary iodine median ＜ 150 μg/L is iodine deficiency,150-＜ 250 μg/L is iodine appropriate,250-＜ 500 μg/L is iodine overdose,and ≥ 500 μg/L is iodine excess.Results Totally 30 967 edible salt samples from children's and pregnant women's households were examined,and the median of salt iodine was 23.85 mg/kg.The coverage rate of iodized salt was 99.46％ (30 799/30 967),the consumption rate of qualified iodized salt was 94.00％ (29 108/30 967).Totally 6 789 children aged 8-10 were examined thyroid volume and detected urinary iodine,the goiter rate was 0.85％ (58/6 789) and the median urinary iodine was 263.54 μg/L.Totally 3 348 urine samples of pregnant women were examined,and the median urinary iodine was 166.71 μg/L.Conclusions The salt iodine content of residents and the goiter rate of children in Hubei Province meet the national standard for eliminating iodine deficiency disorders.The iodine nutrition level of children and pregnant women is iodine appropriate or iodine overdose.The iodine nutrition level monitoring of key populations should be continuously strengthened.
