his cross-sectional study employed convenience sampling to enroll 1 994 community-dwelling older adults (aged ≥65 years) undergoing health examinations at a Guangzhou community hospital between January and December 2024, aiming to investigate associations between blood lipid profiles and cognitive impairment. Cognitive function was assessed using the AD8 scale, with demographic characteristics (age, sex, education, occupation), health status (hypertension, diabetes mellitus), and lifestyle factors (smoking/alcohol use) collected via questionnaires. Fasting blood samples quantified triglycerides (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C). Propensity score matching (PSM) balanced baseline characteristics between lipid-level groups. Pre-PSM analyses revealed significant intergroup differences: TG groups differed in sex, BMI, alcohol use, hypertension, and self-rated health ( P<0.05); TC groups in sex, age, occupation, diabetes, and hypertension; LDL-C groups in sex, age, occupation, diabetes, hypertension, and daily living ability; HDL-C groups in sex, age, education, occupation, BMI, smoking, diabetes, and hypertension. Post-PSM adjustment eliminated baseline differences ( P>0.05). Multivariable logistic regression adjusted for demographic, clinical, and lifestyle factors demonstrated that elevated TG levels conferred a 48% reduced risk of cognitive dysfunction [ OR (95% CI): 0.52 (0.29-0.94)], whereas TC, LDL-C, and HDL-C showed no significant associations (all P>0.05). These findings suggest an inverse association between higher triglyceride levels and cognitive dysfunction risk in older adults, highlighting TG′s potential protective role in cognitive health.

Objective:To analysis of the efficacy and safety of entecavir monotherapy and entecavir combined with probiotic therapy in the treatment of hepatitis B cirrhosis.Methods:A total of 88 patients with hepatitis B cirrhosis diagnosed and treated in Binzhou Central Hospital from May 2020 to May 2022 were prospectively selected as the study objects, and divided into the control group (44 cases) and the observation group (44 cases) according to random number table method. The control group was given entecavir monotherapy, and the observation group was given entecavir combined with probiotics. The levels of intestinal flora, blood ammonia (BUN), liver function index and liver fibrosis were compared between the two groups before and after treatment, and the clinical efficacy after 3 months of treatment and the occurrence of adverse reactions during treatment were compared between the two groups.Results:After treatment, the ratio of harmful/beneficial bacteria, serum BUN, total bilirubin (TBIL), alanine aminotransferase (ALT), azelaic aminotransferase (AST), glutamyltransferase (GGT), pre-collagen type Ⅲ(PCⅢ), collagen type Ⅳ (Ⅳ-C), laminin (LN), and hyaluronidase (HA) in the observation group were lower than those in the control group: (10.52 ± 1.35)% vs. (11.38 ± 2.19)%, (70.26 ± 6.94) μmol/L vs. (76.34 ± 10.59) μmol/L, (32.76 ± 4.27) μmol/L vs. (36.82 ± 6.41) μmol/L, (51.82 ± 6.37) U/L vs. (56.34 ± 5.74) U/L, (37.83 ± 5.61) U/L vs. (42.75 ± 12.89) U/L, (42.67 ± 11.84) U/L vs. (48.16 ± 13.49) U/L, (118.76 ± 23.65) μg/L vs. (129.24 ± 21.16) μg/L, (74.34 ± 17.58) μg/L vs.(82.39 ± 20.05) μg/L, (127.65 ± 12.23) mg/L vs. (138.97 ± 11.76) mg/L, (107.78 ± 23.47) mg/L vs. (119.65 ± 22.35) mg/L, there were statistical differences ( P<0.05). During the 3-month treatment period, the total effective rate in the observation group was higher than that in the control group and the total incidence of adverse reactions was lower than that in the control group: 88.64%(39/44) vs. 70.45%(31/44), 4.55%(2/44) vs. 18.18%(8/44), there were statistical differences ( χ2 = 4.47, 4.06, P<0.05). Conclusions:In the treatment of hepatitis B cirrhosis patients, entecavir combined with probiotics can effectively regulate gastrointestinal function, reduce BUN level, and then more conductive to liver function recovery, reduce the process of liver fibrosis, improve efficacy, and reduce the occurrence of adverse reactions.

Objective:To evaluate the diagnostic efficacy and practicality of the Jaundice color card (JCard) as a screening tool for neonatal jaundice.Methods:Following the standards for reporting of diagnostic accuracy studies (STARD) statement, a multicenter prospective study was conducted in 9 hospitals in China from October 2019 to September 2021. A total of 845 newborns who were admitted to the hospital or outpatient department for liver function testing due to their own diseases. The inclusion criteria were a gestational age of ≥35 weeks, a birth weight of ≥2 000 g, and an age of ≤28 days. The neonate′s parents used the JCard to measure jaundice at the neonate′s cheek. Within 2 hours of the JCard measurement, transcutaneous bilirubin (TcB) was measured with a JH20-1B device and total serum bilirubin (TSB) was detected. The Pearson′s correlation analysis, Bland-Altman plots and the receiver operating characteristic (ROC) curve were used for statistic analysis.Results:Out of the 854 newborns, 445 were male and 409 were female; 46 were born at 35-36 weeks of gestational age and 808 were born at ≥37 weeks of gestational age. Additionally, 432 cases were aged 0-3 days, 236 cases were aged 4-7 days, and 186 cases were aged 8-28 days. The TSB level was (227.4±89.6) μmol/L, with a range of 23.7-717.0 μmol/L. The JCard level was (221.4±77.0) μmol/L and the TcB level was (252.5±76.0) μmol/L. Both the JCard and TcB values showed good correlation ( r=0.77 and 0.80, respectively) and agreements (96.0% (820/854) and 95.2% (813/854) of samples fell within the 95% limits of agreement, respectively) with TSB. The JCard value of 12 had a sensitivity of 0.93 and specificity of 0.75 for identifying a TSB ≥205.2?μmol/L, and a sensitivity of 1.00 and specificity of 0.35 for identifying a TSB ≥342.0?μmol/L. The TcB value of 205.2?μmol/L had a sensitivity of 0.97 and specificity of 0.60 for identifying TSB levels of 205.2 μmol/L, and a sensitivity of 1.00 and specificity of 0.26 for identifying TSB levels of 342.0 μmol/L. The areas under the ROC curve (AUC) of JCard for identifying TSB levels of 153.9, 205.2, 256.5, and 342.0 μmol/L were 0.96, 0.92, 0.83, and 0.83, respectively. The AUC of TcB were 0.94, 0.91, 0.86, and 0.87, respectively. There were both no significant differences between the AUC of JCard and TcB in identifying TSB levels of 153.9 and 205.2 μmol/L (both P>0.05). However, the AUC of JCard were both lower than those of TcB in identifying TSB levels of 256.5 and 342.0 μmol/L (both P<0.05). Conclusions:JCard can be used to classify different levels of bilirubin, but its diagnostic efficacy decreases with increasing bilirubin levels. When TSB level are ≤205.2 μmol/L, its diagnostic efficacy is equivalent to that of the JH20-1B. To prevent the misdiagnosis of severe jaundice, it is recommended that parents use a low JCard score, such as 12, to identify severe hyperbilirubinemia (TSB ≥342.0 μmol/L).

Objective: To understand environmen and sanitation of rural schools in western China, and to provide data support and reference for improving school environmental conditions and facilities and promoting the healthy development of students. Methods: Based on the "School Comprehensive Environmental Improvement Project", a total of 38 087 students from 60 primary school from were randomly selected from 5 provinces in western China from September to December 2018. Environment and sanitation of schools was investigated through interviews, on site observation and inquiry, so as to obtain the survey data. Results: All schools had water supply, 80.0% (48) could meet the needs of teachers and students, 91.7% (55) provided drinking water facilities, 93.3 % (56) provided hand washing facilities, and 66.7% (40) provided soap and other cleaning supplies for students. 71.7% (43) of the schools had sanitary toilets, 40.0% (24) toilets were qualified for femail, 86.7% (52) were clean and 58.3% (35) were odorless. The garbage disposal methods of schools are mainly collected by professional institutions, supplemented by fixed point stacking, accounting for 45.0% (27) and 35.0% (21) respectively. About 30% (22, 17, 20) of school sewage is discharged by open ditch, underground ditch and pipeline. 93.3% (56) of schools offered health education courses, 91.7% (55) had sanitation system, 70.0% (42) had drinking water sanitation management system, and 41.7% (25) had toilet management system. Conclusion The basic environmental sanitation facilities in the school are well equipped, and there are some problems to be improved in the establishment of environmental sanitation management system and the provision of hand washing and cleaning supplies.

Methods:All the literatures published in Chinese Journal of Preventive Medicine from 2014 to 2017 were retrieved through the Chinese Medical Citation index, and the citation frequency data in China′s core journals of science and technology from 2014 to 2018 was obtained through Institute of Scientific and Technical Information of China. The citation status of articles published in Chinese Journal of Preventive Medicine was statistically analyzed by the scientometric method. The main indicators included the citation rate of articles published in each year, the citation frequency of all articles, the citation status of individual papers and authors, the regional and high-yield institution distribution of cited authors, and the main citation journals. Results:From 2014 to 2017, a total of 929 articles were published in 19 columns of Chinese Journal of Preventive Medicine,and the number of each year was 253 (27.23%), 231 (24.87%), 224 (24.11%) and 221 (23.79%), respectively. The total number of published pages was 3 564, and the average number of articles was 3.45 pages. A total of 28 key topics have been published. The total citation was 3 861 times, with 4.16 times per paper. Among them, 161 papers were not cited，accounting for 17.33%. The maximum citation frequency of a single paper was 49 times. There were good citations in the columns of original article and methodology introduction. There was no correlation between fund project support and paper citation. But the cited rate (93.67%) and cited frequency of special issue ［ M ( P25, P75)=3 (1, 6)］ were higher compared with the cited rate (80.42%; χ 2=16.08, P<0.001) and cited frequency ［ M ( P25, P75)=2 (1, 6); Z=2.56, P=0.010] of free-lance articles. A total of 15 authors were cited more than 25 times, and 15 articles were cited more than 20 times. There were 213 institutions involved in the 768 cited papers, among which 12 institutions were cited more than 50 times. The authors of the cited papers were distributed in 28 provinces (autonomous regions, municipalities directly under the central government). From 2014 to 2018, a total of 281 journals cited the papers published in our journal, of which 12 journals cited more than 50 times. Conclusion:The quality of the literature in Chinese Journal of Preventive Medicine is high and the journal has a strong influence in the field of preventive medicine and public health in China.
