Objective: To explore the assocation of the family environment and depressive symptoms among primary and middle school students, so as to provide suggestions for further maximizing the utility of family environment in the growth of primary and secondary school students, as well as prevention and intervention of depressive symptoms among children and adolescents. Methods: From June to July 2024, through a multistage cluster random sampling method, 8 800 primary and middle school students aged 10 to 18 from 36 schools in 3 cities (Datong, Lvliang, Linfen) in Shanxi Province. A self designed questionnaire was used to conduct a family environment survey, including family socioeconomic conditions, family structure, family parenting behavior, family member health behavior, etc; and the depression symptoms of primary and secondary school students were investigated by Patient Health Questionnaire-9. The χ 2 test and binary Logistic regression to method were used to analyze the association of the family environment with depressive symptoms among primary and secondary school students, and to analyze gender and urban-rural heterogeneity in this association. Results: The detection rate of depressive symptoms among primary and middle school students was 46.7% ( n = 4 111 ). Among them, the detection rates of depressive symptoms for male and female students were 45.7% and 47.7% respectively, and the detection rates for rural and urban students were 48.0% and 44.9% respectively. The results of binary Logistic regression model showed that in the family environment, factors such as the father s education level (junior high school: OR =0.84), self assessed family socio economic status (average: OR =0.78, good: OR =0.80), parental support and understanding (yes: OR = 0.55 ), family atmosphere (harmonious: OR =0.66), living arrangement (living only with father or mother: OR =1.31, living with parents and grandparents: OR =1.19), and family rearing style (combining punishment and reward: OR =1.42, punishment only: OR =1.25) were related to depressive symptoms in primary and middle school students in Shanxi Province ( P <0.05). From the perspective of gender heterogeneity, the living arrangement (living only with father or mother: OR =1.67, others: OR =1.67) had a statistically significant association with depressive symptoms in male students ( P <0.05). From the perspective of urban rural heterogeneity, the living arrangement (living only with father or mother: OR =1.38) had a statistically significant association with depressive symptoms in rural primary and middle school students ( P <0.05). Conclusions The family environment has an important impact on depressive symptoms in primary and middle school students. Family functioning should be fully exerted to prevent depressive symptoms in primary and middle school students.

OBJECTIVE To explore the pharmacokinetic characteristics of 3 blood-absorbed components of Xiangshao sanjie oral liquid in rats with hyperplasia of mammary gland （HMG）. METHODS Female SD rats were divided into control group and HMG group according to body weight， with 6 rats in each group. The HMG group was given estrogen+progesterone to construct HMG model. After modeling， two groups were given 1.485 g/kg of Xiangshao sanjie oral liquid （calculated by crude drug） intragastrically， once a day， for 7 consecutive days. Blood samples were collected before the first administration （0 h）， and at 5， 15， 30 minutes and 1， 2， 4， 8， 12， 24 hours after the last administration， respectively. Using chlorzoxazone as the internal standard， the plasma concentrations of ferulic acid， paeoniflorin and rosmarinic acid in rats were detected by UPLC-Q/TOF-MS. The pharmacokinetic parameters [area under the drug time curve （AUC0－24 h， AUC0－∞）， mean residence time （MRT0－∞）， half-life （t1/2）， peak time （tmax）， peak concentration （cmax）] were calculated by the non-atrioventricular model using Phoenix WinNonlin 8.1 software. RESULTS Compared with the control group， the AUC0－24 h， AUC0－∞ and cmax of ferulic acid in the HMG group were significantly increased （P＜0.05）； the AUC0－24 h， AUC0－∞ ， MRT0－∞ ， t1/2 and cmax of paeoniflorin increased， but there was no significant difference between 2 groups （P＞0.05）； the AUC0－24 h and MRT0-∞ of rosmarinic acid were significantly increased or prolonged （P＜0.05）. C ONCLUSIONS In HMG model rats， the exposure of ferulic acid， paeoniflorin and rosmarinic acid in Xiangshao sanjie oral liquid all increase， and the retention time of rosmarinic acid is significantly prolonged.

Objective To evaluate the surgical efficacy of unilateral pneumonectomy for the treatment of tuberculous destroyed lung, analyze the causes of severe postoperative complications, and explore clinical management strategies. Methods A retrospective analysis was conducted on the clinical data of patients with tuberculous destroyed lung who underwent unilateral pneumonectomy at the Public Health Clinical Center of Chengdu from 2017 to 2023. Postoperative severe complications were statistically analyzed. Patients were divided into a non-severe complication group and a severe-complication group, and the causes, management, and outcomes of complications were analyzed. Results A total of 134 patients were included, comprising 69 males and 65 females, with a mean age of 17-73 (40.43±12.69) years. There were 93 patients undergoing left pneumonectomy and 41 patients undergoing right pneumonectomy. Preoperative sputum smear was positive in 35 patients, all of which converted to negative postoperatively. There were 58 patients with hemoptysis preoperatively, and none experienced hemoptysis postoperatively. Postoperative incisional infection occurred in 8 (5.97%) patients, and postoperative pulmonary infection in 26 (19.40%) patients. Severe postoperative complications occurred in 17 (12.69%) patients, including empyema in 9 (6.72%) patients, bronchopleural fistula with empyema in 1 (0.75%) patient, severe pneumonia in 3 (2.24%) patients, postpneumonectomy syndrome in 1 (0.75%) patient, chylothorax in 1 (0.75%) patient, ketoacidosis in 1 (0.75%) patient, and heart failure with severe pneumonia in 1 (0.75%) patient. Perioperative mortality occurred in 2 (1.49%) patients, both of whom underwent right pneumonectomy. Multivariate logistic regression analysis revealed that a history of ipsilateral thoracic surgery, concomitant Aspergillus infection, and greater blood loss were independent risk factors for severe complications following unilateral pneumonectomy for tuberculous destroyed lung (P<0.05). Conclusion Unilateral pneumonectomy for patients with tuberculous destroyed lung can significantly improve the clinical cure rate, sputum conversion rate, and hemoptysis cessation rate. However, there is a certain risk of severe perioperative complications and mortality, requiring thorough perioperative management and appropriate management of postoperative complications.

OBJECTIVE To analyze chemical components of Yao ethnic medicine Pittosporum pauciflorum， establish its fingerprint and investigate the spectrum-effect relationship of its anti-inflammatory effect. METHODS UHPLC-Q-Orbitrap-MS technology was used to analyze the chemical components of P. pauciflorum （batch S6）. The fingerprints for 10 batches of P. pauciflorum from different producing areas in Guangxi Province （batches S1-S10） were established by HPLC， and similarity assessment and chemometric pattern recognition analysis were conducted. RAW264.7 inflammatory cell model was induced by lipopolysaccharide， and the anti-inflammatory activity of P. pauciflorum was investigated. Using inhibition rates of nitric oxide （NO）， tumor necrosis factor-α （TNF-α）， interleukin-6 （IL-6） and IL-1β as efficacy indicators， grey relational analysis and partial least squares regression analysis were adopted to evaluate the spectrum-effect relationship of the anti-inflammatory effect of P. pauciflorum. RESULTS There were 60 chemical components， including flavonoids， phenolic acids， lipids， etc.， identified in P. pauciflorum. The fingerprints for 10 batches of P. pauciflorum showed 14 common peaks，with similarity values ranging from 0.883 to 0.991. Three common peaks were assigned neochlorogenic acid （peak 5）， chlorogenic acid （peak 7）， and syringaldehyde （peak 10）. The classification results of the systematic clustering analysis and the principal component analysis were basically consistent. Batches S1 to S10 of P. pauciflorum significantly reduced the levels of NO， TNF-α， IL-6 （except for batch S5） and IL-1β in the cell supernatant （P＜0.05 or P＜0.01）. Inhibition rates of above inflammatory indexes were 10.26%-39.96%， 14.96%-31.36%， 1.38%-21.27%， 18.54%-28.00%， respectively. The contents of neochlorogenic acid， syringaldehyde， as well as the components corresponding to peaks 1， 3， 9， 12 and 14，exhibited a strong correlation with the anti-inflammatory effects of P. pauciflorum. CONCLUSIONS The present study has analyzed the chemical components of P. pauciflorum and established HPLC fingerprints for 10 batches of P. pauciflorum. Each batch of medicinal herbs demonstrates certain anti- inflammatory activities， among which neochlorogenic acid， syringaldehyde， and the components corresponding to peaks 1， 3， 9， 12 and 14 are likely to be the active anti-inflammatory components.

Objective To investigate the prevalence of Anisakis infections in coastal marine fishes and awareness of anisakiasis control knowledge among local residents in Yantai City, Shandong Province in 2021, so as to provide insights into formulation of anisakiasis control interventions. Methods Marine fishes were purchased from Shunxin Port, Yantai City, Shandong Province in November 2021, and the presence of Anisakis was detected in different species of fishes and different fish sites. The correlations between body length and weight of marine fish and intensity of Anisakis infections were examined using Spearman’s rank correlation analysis, and the dietary habits and anisakiasis control knowledge were investigated using questionnaire surveys among local residents. Results A total of 201 marine fishes belonging to 20 species were dissected, and Anisakis was detected in 77 marine fishes (38.31%) belonging to 11 species (55.00%), with a mean infection intensity of 45.04 parasites per fish (3 468/77). Spearman’s rank correlation analysis revealed that the body length (r_s = 0.74, P < 0.05) and weight (r_s = 0.79, P < 0.01) of the monkfish correlated positively with the intensity of Anisakis infections, and the body length (r_s = 0.68, P < 0.05) of the flatfish correlated positively with the intensity of Anisakis infections, while no correlations were examined between the body length or weight of other marine fishes and the intensity of Anisakis infections. Of all respondents, 53.38% men and 56.67% women did not know anisakiasis control knowledge at all, and there was a significant difference in the proportion of respondents using separate chopping boards for raw and cooked food from different villages (χ² = 17.89, P < 0.01), while there was an age-specific proportion of respondents with habitats of eating raw or semi-raw seafood (χ² = 28.27, P < 0.01). Conclusions The prevalence and intensity of Anisakis infections were high in coastal marine fishes in Yantai City in 2021, and the awareness of anisakiasis control knowledge was low among local residents. Intensified health education pertaining to anisakiasis control knowledge is recommended to reduce the risk of Anisakis infections.

Objective To investigate the effect of nobiletin(Nb)on lipopolysaccharide(LPS)-induced inflammatory injury of mesangium cells(HBZY-1)by regulating AMP-activated protein kinase(AMPK)/NOD-like receptor protein 3(NLRP3)signaling pathway.Methods HBZY-1 cells were separated into 5 groups:normal control(NC)group,LPS group(100 ng·mL-1 LPS),and Nb group(100 ng·mL-1 LPS+40 μmol·L-1 Nb),Rapamycin(Rap,AMPK/NLRP3 signaling pathway inhibitor)group[100 ng·mL-1 LPS+0.5 μmol·L-1 Rap],and Nb+Rap group(100 ng·mL-1 LPS+40 μmol·L-1 Nb+0.5 μmol·L-1 Rap).MTT was applied to detect the cytotoxicity and proliferation of HBZY-1 cells.ELISA was applied to detect the contents of interleukin(IL)-1β,IL-6,tumor necrosis factor-α(TNF-α),catalase(CAT),superoxide dismutase(SOD),and glutathione(GSH)in HBZY-1 cells.Flow cytometry was used to detect cell apoptosis.Western Blot was applied to detect the protein levels of AMPK/NLRP3 signaling pathway.Results Compared with the NC group,the levels of CAT,SOD,GSH,cell OD value,and the level of AMPK protein in the LPS group were significantly reduced(P＜0.05).The apoptosis rate,contents of IL-1β,IL-6,TNF-α,and the level of NLRP3 protein were significantly increased(P＜0.05).Compared with the LPS group,the levels of CAT,SOD,GSH,OD value,and the level of AMPK protein in the Nb group were significantly increased(P＜0.05).The apoptosis rate,contents of IL-1β,IL-6,TNF-α,and the level of NLRP3 protein were significantly decreased(P＜0.05),while the above indicators in the Rap group showed an opposite trend to the Nb group(P＜0.05).Compared with the Nb group,the above indicators in the Nb+Rap group also showed an opposite trend to the Nb group(P＜0.05).Conclusion Nb may alleviate LPS-induced inflammatory injury to MC cells by up-regulating the AMPK/NLRP3 signaling pathway.But down-regulation of the AMPK/NLRP3 signaling pathway may eliminate the improvement effect of Nb on LPS-induced inflammatory injury in MC cells.

OBJECTIVE To create a highly effective algorithm for automatically generating easily confused drug catalogs （ECDC）， as well as to develop a management system for ECDC based on this algorithm， in order to improve the management efficiency of ECDC. METHODS This study， based on Levenshtein distance algorithm， delved deeply into the automatic identification mechanism of easily confused drugs and the screening method for determining similarity thresholds， ultimately leading to the development of an algorithm for automatically generating ECDC. Besides a management system was designed and developed， using SQL Server 2008 R2 Express as the data storage platform and Visual Basic.NET as the programming language. RESULTS The similarity threshold δ played a crucial role in the algorithm for automatically generating ECDC. As the value of δ gradually increased， the total count of easily confused drugs decreased gradually， while the count of drug groups exhibited a pattern of initially increasing and then decreasing. Practically， ECDC could be created using either the generic or varietal names of drugs， with corresponding similarity thresholds of 0.75 and 0.83. Furthermore， ECDC management system had significantly reduced the time required to establish a catalog from about one week to less than one hour， resulting in a substantial enhancement in work efficiency. CONCLUSIONS The algorithm used to automatically generate ECDC is highly efficient and rapid， offering robust technical assistance for the management of easily confused drugs. Implementing the ECDC system can greatly reduce the time cost related to building and maintaining the catalogs， thus significantly improving the efficiency of managing ECDC.

Objective To analyze the epidemiological characteristics of new elderly malignant tumor cases in Tongren City from 2018 to 2022, so as to provide a theoretical basis for the prevention and control of elderly malignant tumor in this area. Methods A retrospective analysis of the epidemiological characteristics of cases aged 60 and above who were first diagnosed with malignant tumors by pathology in our hospital from 2018 to 2022 was conducted based on the International Classification of Diseases (ICD-10). Results The incidence rate of elderly malignant tumors in Tongren City increased from 123.83/100 000 in 2018 to 126.14/100 000 in 2022, and the incidence rate showed a trend of first rising and then declining. The top five tumors in incidence rate are lung cancer, rectal cancer, liver cancer, stomach cancer and cervical cancer. The tumor order has changed over the years except lung cancer, which was the first. Lung cancer was the main high incidence tumor among the elderly of all ages. With the increase of age, the number of bladder cancer patients increases significantly, and the number of colon cancer patients also shows an upward trend. The prevalence rate of lung cancer（χ²=16.032，P=0.014) , liver cancer（χ²=8.099，P=0.030) , bladder cancer（χ²=11.274 , P=0.018) , and gastric cancer（χ²=19.387 , P=0.011) in elderly people of different sexes was generally higher in men than in women, and the difference was statistically significant (P<0.05). Conclusion Lung cancer , rectal cancer and liver cancer, as the malignant tumors with high case composition and rapid increase in the elderly, can be the focus of early screening and prevention of malignant tumors in the elderly in Tongren City, and men should pay more attention.

Objective: To investigate factors associated with life satisfaction among adolescents who have been relocated for poverty alleviation,so as to provide scientific evidence to support adolescent physical and mental well being. Methods: A multi stage stratified random sampling was conducted from June to August 2023 across 24 relocation sites in 8 counties of 4 cities in Shanxi Province. A total of 631 adolescents aged 10-19 were surveyed regarding personal characteristics, family environment, health behaviors, mental health, and social capital. Univariate analysis of variance and binary Logistic regression were used to explore the influencing factors. Results: The life satisfaction rate of the relocated adolescents was 63.9%(403/631), and the average score of life satisfaction was (23.21±6.28). The Logistic regression analysis showed that, significant factors affecting life satisfaction of the relocated adolescents included age (17-19 years old: AOR= 0.54 , 95%CI =0.33-0.88), subjective family economic status (moderate: AOR=1.70, 95%CI =1.04-2.76; good: AOR=6.95, 95%CI =1.85-26.16), sleep quality (good: AOR=1.61, 95%CI =1.09-2.38), depression ( AOR=0.94, 95%CI =0.90-0.99), and social capital ( AOR=1.17, 95%CI =1.10-1.23)( P <0.05). Conclusions The satisfaction of 17-19 year old adolescents who have relocated for poverty alleviation is relatively low, while those with better family economic status, high sleep quality, low depression level and rich social capital showed high life satisfaction. Targeted interventions by families, communities, schools, and social institutions are recommended to improve adolescents quality of life.
