ABSTRACT

【Objective】 To examine risk factors for acute pancreatitis (AP) in individuals with chronic alcohol consumption habits. 【Methods】 The study incorporated participants from the initial survey (2006-2010) and subsequent follow-ups (2014+) taken from the UK Biobank database, with the observation period ending on November 30, 2022. During this period, 176 individuals were newly diagnosed with AP, while 59,512 remained unaffected. Vital characteristics of the target population, such as their medical histories, surgical experiences and dietary patterns, were collected during the enrolment phase (2006-2010). The Cox proportional hazard model was employed to ascertain whether these characteristics were potent risk factors for AP. Concurrently, a subgroup from the target population with documented drinking behavior was selected. The multivariate Cox proportional hazard model was utilized to analyze the relationship of the established factors, variances in alcohol consumption, and increased alcohol intake (Δ) with the onset of AP, and whether the additional alcohol intake served as a risk factor. 【Results】 Multivariate analysis revealed that consumption quantity of cooked vegetables inversely correlated with AP risk (HR=0.44, 0.39, 0.42 and 0.41 for one, two, three and four+ tablespoons per day, respectively, as compared to non-consumers). Coffee consumption (2-3 cups per day) also reduced AP risk (HR=0.45 for 2 cups/day; HR=0.39 for 3 cups/day as compared to non-coffee drinkers). However, those with biliary disease without cholecystectomy exhibited a marked increase in AP risk (HR=7.82), which reduced albeit remained elevated for those with biliary disease post-cholecystectomy (HR=2.15). Subgroup analysis showed minimal impact of alcohol intake levels on AP incidence. Yet, increased alcohol consumption (Δ of 1 bottle/week) was linked to a heightened AP risk (HR=1.05, 95% CI:1.02-1.09, P<0.05). 【Conclusion】 Among longstanding alcohol consumers, a diet rich in cooked vegetables and moderate coffee consumption offers protective effects against AP. Conversely, biliary disease (particularly without cholecystectomy) and elevated alcohol intake present considerable risk factors for the development of this condition.

ABSTRACT

Objective@#To explore the relationship between depressive symptoms, negative life events and resilience among primary and secondary school teachers, so as to provide a reference for mental health promotion in school teachers.@*Methods@#During November to December 2022, a questionnaire survey was conducted using convenient cluster sampling method to select 11 332 in service teachers from 38 schools in 8 provinces (cities) including Beijing, Guangdong, Anhui, Hubei, Sichuan, Xinjiang, Liaoning, and Heilongjiang. The Patient Health Questionnaire-9 items, a self developed 21-item Adverse Life Events questionnaire, and a 10-item Conner-Davidson Resilience Scale were used to assess depressive symptoms, experiences of negative life events, and resilience levels of the teachers, respectively. The relationship between depressive symptoms, negative life events and psychological resilience were analyzed by multiple linear regression and stratified regression.@*Results@#The detection rate of depressive symptoms among primary and secondary school teachers was 14.0%. Negative life events of primary and secondary school teachers were positively correlated with depressive symptoms ( r =0.35), while psychological resilience was negatively correlated with depressive symptoms ( r =-0.45) ( P <0.05). After adjusting for possible covariates including gender and marital status, negative life events were positively correlated with depressive symptoms ( β=0.22, P <0.01). Resilience played a moderating role in the association of negative life events with depressive symptoms among primary and secondary school teachers ( B=-0.15, P <0.01).@*Conclusions@#Negative life events experiences are associated with higher level of depressive symptoms among school teachers. However, resilience might mitigate the negative effects of negative life events on depressive symptoms, playing a protective role in teachers mental health.

ABSTRACT

Objective:To establish the HPLC fingerprint of Bolbostemmatis Rhizoma standard decoction; To determine the three effective components with similar structure by quantitative analysis of multi-components by single marker (QAMS); To evaluate the quality of Bolbostemmatis Rhizoma standard decoction.Methods:HPLC was adopted to establish the fingerprints of 15 batches of Bolbostemmatis Rhizoma standard decoction. The Chromatographic column was Waters XBridge Phenyl (4.6 mm×250 mm, 5 μm). The mobile phase was acetonitrile-0.1% phosphoric acid solution with gradient elution. Cluster analysis (HCA) and principal component analysis (PCA) were conducted based on the relative peak area of common peaks. The same method as the fingerprint was used to establish QAMS of tubeimoside A, B, C on Bolbostemmatis Rhizoma standard decoction.Results:There were 14 common peaks in the fingerprint of Bolbostemmatis Rhizoma standard decoction. It was confirmed that the peak 3 was L-tryptophan, the peak 11 was tubeimoside B, the peak 12 was tubeimoside C, and the peak 13 was tubeimoside A. 15 batches of Bolbostemmatis Rhizoma standard decoction from different origins were divided into 3 categories by HCA and PCA. There was no significant difference between QAMS and the external standard method (ESM) through the system suitability inspection. Conclusion:This method is accurate, reliable and has good specificity, which can effectively evaluate the quality of Bolbostemmatis Rhizoma standard decoction.

ABSTRACT

Background As a group of environmental pollutants, polycyclic aromatic hydrocarbons (PAHs) are neurotoxic and may cause mild cognitive impairment (MCI) by inducing inflammation. Whether neutrophil-lymphocyte ratio (NLR), an inflammatory indicator, plays a mediating role in the relationship between PAHs exposure and MCI is unclear yet. Objective To investigate a potential mediating role of NLR in the association between exposure to PAHs and MCI in coke oven plant workers. Methods Eleven urine hydroxylated PAHs (OH-PAHs) of 530 coke oven plant workers were determined by high performance liquid chromatography tandem mass spectrometry. NLR was derived from participants' routine blood examination results using a fully automated haematology analyser. The associations between urinary OH-PAHs and MCI were analyzed by binary logistic regression, the associations between urinary OH-PAHs and NLR were analyzed by multiple linear regression, and the role of NLR in the relationship between urinary OH-PAHs and MCI was evaluated by mediating effect analysis. Results After controlling for confounding factors and other OH-PAHs, the results of binary logistic regression showed that for every e-fold (e is the base of the natural logarithm) increase in the concentration of 2-hydroxynaphthalene (2-OHNap) and 1-hydroxyphenanthrene (1-OHPhe), the OR (95%CI) values of reporting MCI positive were 1.21 (1.02, 1.43) and 1.25 (1.04, 1.51) respectively. For each unit increase of NLR, the OR (95%CI) of reporting MCI positive was 1.56 (1.12, 2.18). The results of multiple linear regression showed that each unit increase in natural log-transformed levels of 1-OHPhe was associated with 0.05 (95%CI: 0.01, 0.10) increase of NLR. The results of mediating effect analysis showed that the association between urinary 1-OHPhe and MCI was partially mediated by peripheral blood NLR, with a mediation ratio of 9.8%. Conclusion Exposure to PAHs in coke oven plant workers may increase the risk of reporting MCI positive partially through increased NLR in peripheral blood.

ABSTRACT

Objective:To analyze the epidemiological trends and major risk attribution of pancreatic cancer in China, Japan and South Korea from 1990 to 2019.Methods:The descriptive epidemiological method was conducted. The overall incidence rate, mortality rate, age-standardized incidence rate (ASIR) and age-standardized mortality rate (ASMR) of pancreatic cancer in China, Japan and South Korea from 1990 to 2019 were collected from the Global Burden of Disease (GBD) Database. Age-standardized rates were calculated based on the worldwide standardized population structure provided by GBD Database 2019. Observation indicators: (1) incidence and motality of pancreatic cancer in China, Japan and South Korea in 2019; (2) age-period-cohort model analysis of incidence and mortality rates of pancreatic cancer in China, Japan and South Korea from 1990 to 2019; (3) trends of ASIR and ASMR of pancreatic cancer in China, Japan and South Korea from 1990 to 2019; (4) trends of major risk attribution of pancreatic cancer related death in China, Japan and South Korea from 1990 to 2019. Count data were represented as absolute numbers, percentages and ratios. Joinpoint V.4.7.0.0 software was used to calculate the annual percentage change (APC), the average annual percentage change (AAPC) of incidence and mortality rates of pancreatic cancer in different time periods and 95% confidence interval (95% CI). The age-period-cohort model in STATA V.15.0 software was used to analyze the influence of different ages, periods and birth cohorts on the risk of onset and death of pancreatic cancer after controlling the other two variables, with the risk effect size described as relative risk (95% CI). Results:(1) Incidence and motality of pancreatic cancer in China, Japan and South Korea in 2019. In 2019, the incidence rate of pancreatic cancer in China increased from 0.07/100,000 among 15-19 years old to 64.01/100,000 among 85-89 years old, with increasing from 0.09/100,000 to 94.71/100,000 in males and from 0.04/100,000 to 47.47/100,000 in females. The mortality rate of pancreatic cancer in China increased from 0.04/100,000 among 15-19 years old to 79.58/100,000 among 85-89 years old, with increasing from 0.05/100,000 to 116.50/100,000 in males and from 0.03/100,000 to 59.69/100,000 in females. The incidence rate of pancreatic cancer in Japan increased from 0.03/100,000 among 15-19 years old to 162.26/100,000 among 85-89 years old, with increasing from 0.03/100,000 to 177.67/100,000 in males and from 0.04/100,000 to 153.67/100,000 in females. The mortality rate of pancreatic cancer in Japan increased from 0.02/100,000 among 15-19 years old to 154.88/100,000 among 85-89 years old, with increasing from 0.02/100,000 to 170.93/100,000 in males and from 0.02/100,000 to 145.94/100,000 in females. The incidence rate of pancreatic cancer in South Korea increased from 0.04/100,000 among 15-19 years old to 136.78/100,000 among 85-89 years old, with increasing from 0.03/100,000 to 153.78/100,000 in males and from 0.04/100,000 to 129.73/100,000 in females. The mortality rate of pancreatic cancer in South Korea increased from 0.02/100,000 among 15-19 years old to 135.98/100,000 among 85-89 years old, with increasing from 0.02/100,000 to 156.21/100,000 in males and from 0.02/100,000 to 127.59/100,000 in females. The peak incidence and mortality of pancreatic cancer in China were found in males aged 65-69 years, and the overall incidence and mortality of males in different age groups were higher than those of females in the same age group. In Japan, the peak incidence of pancreatic cancer occurred in females aged 80-84 years and the peak mortality occurred in males aged 75-79 years. The morbidity and mortality of males aged <80 years were higher than those of females in the same age group, while the morbidity and mortality of males aged ≥80 years were lower than those of females in the same age group. In South Korea, the peak incidence of pancreatic cancer occurred in females aged 80-84 years, and the peak mortality occurred in males aged 70-74 years. The morbidity and mortality of males aged <75 years were higher than those of females in the same age group, while the morbidity and mortality of males aged ≥75 years were lower than those of females in the same age group. (2) Age-period-cohort model analysis of incidence and mortality rates of pancreatic cancer in China, Japan and South Korea from 1990 to 2019. Age effect: after adjustment for the period and cohort effects, the risk of incidence and mortality rates of pancreatic cancer in both males and females of China, Japan and South Korea increased with age, which is more obvious in females than males, and more obvious in Japanese than Chinese and Korean populations. Period effect: after adjustment for age and cohort effects, the risk of incidence and mortality rates of pancreatic cancer in both males and females of China, Japan and South Korea increased from 1990 to 2019, with the period effect more significant in the Chinese population. Cohort effect: after adjustment for age and period effects, the risk of morbidity and mortality rates of pancreatic cancer decreased with the passage of birth cohort in China, Japan and South Korea. (3) Trends of ASIR and ASMR of pancreatic cancer in China, Japan and South Korea from 1990 to 2019. The ASIR and ASMR of pancreatic cancer in China increased yearly from 1990 to 2019, and the ASIR and ASMR in 2019 were 1.82 times and 1.79 times those in 1990, respectively. The ASIR and ASMR of pancreatic cancer in Japan showed a slowly increasing trend, and the ASIR and ASMR in 2019 were 1.09 times and 1.05 times those in 1990, respectively. The ASIR and ASMR of pancreatic cancer in South Korea increased firstly, then decreased, and slowly increased. From 1990 to 2019, the AAPC of ASIR of pancreatic cancer in China was 2.08% (95% CI as 1.91% to 2.24%, P<0.05) and AAPC of ASMR was 2.02% (95% CI as 1.86% to 2.19%, P<0.05). The AAPC of ASIR of pancreatic cancer in Japan was 0.28% (95% CI as 0.15% to 0.42%, P<0.05) and AAPC of ASMR was 0.13% (95% CI as 0.03% to 0.24%, P<0.05). The AAPC of ASIR of pancreatic cancer in South Korea was 0.50% (95% CI as 0.21% to 0.80%, P<0.05) and AAPC of ASMR was 0.15% (95% CI as -0.10% to 0.40%, P>0.05). (4) Trends of major risk attribution of pancreatic cancer related death in China, Japan and South Korea from 1990 to 2019. The main risk factors for pancreatic cancer related death in China, Japan and South Korea from 1990 to 2019 were smoking, high fasting glucose and high body mass index (BMI). The trend of pancreatic cancer related death, mainly attributed to smoking, showed that the proportion of Chinese males increased from 31.4% in 1990 to 34.1% in 2000, then decreased to 31.1% in 2015, and then showed a slow increase to 31.7% in 2019. The proportion of Chinese females increased from 6.7% in 1990 to 10.4% in 2005 and then dropped to 8.7% in 2019. The proportion of Japanese males decreased from 38.8% in 1990 to 26.9% in 2019 and the proportion of Japanese females decreased from 20.9% in 1990 to 14.8% in 2019. The proportion of South Korean males decreased from 37.5% in 1990 to 30.3% in 2019 and the proportion of South Korean females decreased from 12.6% in 1990 to 10.0% in 2019. The trend of pancreatic cancer related death proportion, mainly attributed to high fasting blood glucose, showed that the proportion of Chinese males increased from 5.9% in 1990 to 7.1% in 2019 and the propor-tion of Chinese females increased from 6.2% in 1990 to 6.8% in 2019. The proportion of Japanese males increased from 7.0% in 1990 to 7.7% in 2019 and the proportion of females increased from 5.0% in 1990 to 5.5% in 2019. The proportion of South Korean males increased from 6.8% in 1990 to 9.7% in 2019 and the proportion of females increased from 6.1% in 1990 to 8.2% in 2019. The trend of pancreatic cancer related deaths proportion, attributed mainly to high BMI, showed that the proportion of Chinese males increased from 1.3% in 1990 to 3.0% in 2019 and the proportion of females increased from 2.1% in 1990 to 4.3% in 2019. The proportion of Japanese males increased from 2.0% in 1990 to 2.4% in 2019 and the proportion of females increased from 3.1% in 1990 to 3.4% in 2019. The proportion of South Korean males increased from 1.9% in 1990 to 3.1% in 2019 and the proportion of females increased from 3.4% in 1990 to 4.3% in 2019. Conclusions:The incidence of pancreatic cancer in China may continue to rise but to be stable in Japan and South Korea. The incidence of pancreatic cancer in females, especially elderly women, needs more attention. Smoking remains the most critical risk factor for pancreatic cancer. More attention should also be paid to the increased risk of pancreatic cancer associated with high BMI and high fasting plasma glucose.

ABSTRACT

Objective:To evaluate the clinical significance of transabdominal ultrasound combined with transvaginal ultrasound in detecting the thickness of the lower anterior wall of uterine scar in women who are pregnant again after cesarean section.Methods:From August 2017 to August 2019, 180 cases of second pregnancy after cesarean section in late pregnancy who admitted to Zhuji People's Hospital were studied.All patients were examined by transabdominal ultrasound and transvaginal ultrasound at 32, 34, 36 and 38 weeks of gestation respectively.The development rate of scar in the lower segment of uterus was compared between abdominal ultrasound and transvaginal ultrasound.The differences of the thickness of the lower segment of the anterior wall of the uterus in patients with different scar healing grades and the change with the increase of gestation cycle were analyzed.The delivery outcome of the patients was followed up and the statistics was made.The differences of delivery mode and the occurrence of precursory uterine rupture was recorded in different scar healing grades.Results:The uterine scar development rate in women who were pregnant again after cesarean section of abdominal ultrasound combined with transvaginal ultrasound(100.00%, 180/180) was significantly higher than that of abdominal ultrasound(58.89%, 106/180) and vaginal ultrasound(91.11%, 164/180) alone(χ 2=93.147, 16.744, all P<0.001). The difference of the thickness of the lower anterior wall was statistically significant( F=35.716-69.247, all P<0.001). The difference of the thickness of the lower anterior wall of the uterine scar between different gestational periods was statistically significant( F=15.965-24.361, all P<0.001). There were statistically significant differences in delivery mode and incidence of threatened uterine rupture between the groups with different scar healing grades(χ 2=39.669, 8.312, all P<0.001). There were statistically significant differences in the amount of bleeding during delivery and within 24 h after delivery between the groups with different scar healing grades( F=19.635, 27.174, all P<0.001). Conclusion:Abdominal ultrasound combined with transvaginal ultrasound can improve the development rate of uterine scar.Detection of the thickness of the lower part of the anterior wall of uterine scar is helpful to guide women to choose a reasonable mode of delivery after cesarean section, and guide doctors to take timely measures to prevent the risk of delivery.

ABSTRACT

Objective@#To understand HIV knowledge and high-risk sexual behaviors among men who have sex with men (MSM) in the HIV-infected students’ social network, and to provide a scentific reference of making targeted and effective measures.@*Methods@#A mixed recruitment method of snowball sampling and respondent driven sampling was used to recruit HIV-infected students with the help of local CDC in Harbin, Tianjin, Xi’an and Chongqing, with demographic information, sexual behaviors and HIV knowledge collected via questionnaire survey.@*Results@#A total of 549 valid questionnaires were analyzed. Among them, the awareness rate of "Guo Ba Tiao" was 90.7% and the awareness rate of "Qing Ba Tiao" was 89.4%, the consistent condom use rate was 59.4%. Among those who were aware of HIV, 40.8% exhibit the mismatch between HIV knowledge and condom use behavior, which was significantly associated with number and types of sex partners. Those who had 1-3 regular male sex partners (1 partner: aOR=2.48, 95%CI=1.61-3.82; 2-3 partners: aOR=2.45,95%CI=1.44-4.15),or 1-3 causal male sex partners (1 partner: a-OR=1.74, 95%CI=1.10-2.77; 2-3 partners: aOR=2.15, 95%CI=1.34-3.46) were more likely for this mismatch. Those who had more than one commercial male sex partner(aOR=3.35, 95%CI=1.15-9.80), or more than one regular female sex partner (aOR=2.49, 95%CI=1.17-5.28), or more than one casual female sex partner(OR=2.80, 95%CI=1.01-7.71), the risk for this mismatch was also high.@*Conclusion@#The mismatch between HIV knowledge and condom use behavior among MSM students from the social network of young students living with HIV/AIDS is severe. It is necessary to carry out tailored HIV intervention to reduce the transmission of HIV among those people.

ABSTRACT

Objective To establish a central serous chorioretinopathy (CSC) model on different strains of rabbits by intravenous injection of adrenaline,which may contribute to related researches of CSC.Methods This study was approved by Bioethics Committee of Fourth Military University and complied with Statement for the Use of Animals in Ophthalmic and Visual Research.Fundus fluorescein angiography (FFA) was initially performed on male New Zealand white rabbits (10),Belgium rabbits (5) and Chinchilla rabbits (10) to make sure that the retinas of subjects were normal.For the New Zealand white rabbits,adrenaline was injected via ear vein at a dose of 0.04 mg/kg once per day for the first 8 weeks and followed by a dose of 0.08 mg/kg for the next 4 weeks,while 0.04 mg/kg adrenaline was injected in the same way for 8 weeks in the Belgium rabbits and Chinchilla rabbits.FFA was performed every week after injection of adrenaline to evaluate the fluorescence leakage in ocular fundus.New Zealand white rabbits were sacrificed in 4 (3 rabbits),8 (3 rabbits) and 12 weeks (4 rabbits) after injection respectively,and Belgium rabbits and Chinchilla rabbits were sacrificed in the 8 weeks after injection.The eyeballs of the rabbits were enucleated to prepare the retinal sections for histopathological examination after hematoxylin-eosin staining.The results of FFA and retinal structure were compared among different strains of rabbits.Results No fluorescence leakage was found by FFA in ocular fundus,and the retinal structure was normal in all the 10 New Zealand white rabbits during the experiment.Fluorescence leakage was found by FFA in 2 Belgium rabbits at 1 week and 2 weeks after injection respectively,and retinal detachment and depigmentation of retinal pigment epithelium (RPE) with an enlarged intercellular space were shown by hematoxylin-eosin staining.For the Chinchilla rabbits,fluorescence leakages were found in 7 rabbits throughout the whole period of adrenaline administration.Circumscribed retinal detachment,depigmentation of RPE with enlarged intercellular space were also found in leakage lesions.Conclusions Repeated intravenous injection of adrenaline can induce CSC-like lesions in colored rabbits but not in albino rabbits.
