BackgroundWith the exacerbation of population aging， the number of elderly patients with mental disorders has increased significantly. The high prevalence of pulmonary infection in the aging population has largely contributed to the increased medical burdens and mortality rate， so preventing pulmonary infection in elderly patients with mental disorders has become a critical challenge in clinical practice. www.crd.york.ac.uk/PROSPERO注册号：CRD42024553735 ObjectiveTo investigate the prevalence and influencing factors of pulmonary infection in elderly patients with mental disorders， so as to provide references for preventing the occurrence of pulmonary infection in this population. MethodsOn July 1， 2024， computer searches of CNKI， China Biomedical Literature Database （CBM）， Wanfang， PubMed， Web of Science， Embase， Cochrane Library and Ovid were conducted from the inception of each database to June 2024. Two researchers independently conducted literature screening， data extraction and quality assessment. Meta-analysis was performed using Stata 16.0. ResultsA total of 17 literature （14 in Chinese， 3 in English） involving 75 724 elderly patients with mental disorders were included. Meta analysis revealed that the incidence rate of pulmonary infection in elderly patients with mental disorders was 20.8% （95% CI： 0.154~0.263）. Subgroup analysis indicated that the incidence rates of pulmonary infection among patients with dementia， schizophrenia， depression and unspecified mental disorders were 21.9% （95% CI： 0.182~0.256）， 20.6% （95% CI： 0.129~0.283）， 18.4% （95% CI： 0.136~0.232） and 5.2% （95% CI： 0.430~0.062）， respectively. In terms of influencing factors， the following were identified as risk factors for pulmonary infection in elderly patients with mental disorders： comorbid diabetes mellitus （OR=1.29， 95% CI： 1.24~1.34）， prolonged bed rest （OR=2.41， 95% CI： 2.10~2.76）， dysphagia （OR=1.76， 95% CI： 1.53~2.03）， smoking history （OR=6.27， 95% CI： 5.97~6.59）， irrational use of antibiotics （OR=2.10， 95% CI： 1.79~2.45）， hypoalbuminemia （OR=1.57， 95% CI： 1.35~1.83）， duration of illness （OR=2.05， 95% CI： 1.79~2.36）， age （OR=9.04， 95% CI： 8.44~9.68）， length of hospital stay （OR=2.68， 95% CI： 1.65~4.34）， use of proton pump inhibitors （OR=1.10， 95% CI： 1.06~1.14）， history of chronic lung disease （OR=1.50， 95% CI： 1.43~1.57）， poor oral hygiene （OR=3.66， 95% CI： 1.01~13.23）， comorbid tumors （OR=3.12， 95% CI： 2.18~4.48）， more than two somatic complications （OR=4.01， 95% CI： 1.08~14.86）， invasive procedures （OR=3.31， 95% CI： 1.81~6.04） and disorders of consciousness （OR=5.57， 95% CI： 2.18~14.24）. ConclusionElderly patients with mental disorders suffer a relatively high prevalence rate of pulmonary infection， and its prevalence rate varies among different types of mental disorders， with the highest rate being observed in patients with dementia. The factors contributing to the development of pulmonary infection are found to include age， duration of illness， smoking history， comorbid somatic complications， dysphagia， disorders of consciousness， hypoalbuminemia， prolonged bed rest， oral hygiene status， irrational use of antibiotics， use of proton pump inhibitor， length of hospital stay and invasive procedures. ［www.crd.york.ac.uk/PROSPERO number： CRD42024553735］

ObjectiveTo investigate the mechanism of Tangbikang dry paste in the prevention and treatment of type 2 diabetic peripheral neuropathy （DPN） based on the glyoxalase-1 （GLO-1）/advanced glycation end products （AGE）/receptor for advanced glycation end products （RAGE） pathway. MethodsA total of 56 Sprague-Dawley rats were randomly divided， with eight assigned to the normal group. The remaining 48 rats were fed a high-fat diet combined with intraperitoneal injection of streptozotocin （STZ） to induce a type 2 diabetes mellitus （T2DM） model. Based on blood glucose levels， the rats were randomly assigned to the model group， Tanglin group （13.5 mg·kg^-1）， metformin group （135 mg·kg^-1）， and Tangbikang dry paste low-， medium-， and high-dose groups （3， 6， 12 g·kg^-1）. Successful modeling of DPN was confirmed by a decrease in mechanical pain threshold in the model group at week 4. Fasting blood glucose， body weight， and mechanical pain threshold were measured every 4 weeks. After 16 weeks of intervention， the pathological morphology of the sciatic nerve was observed using hematoxylin-eosin （HE） staining. The expression of RAGE， AGE， protein kinase C （PKC）， and collagen （COL） in the sciatic nerve was assessed by immunohistochemistry. The mRNA expression of RAGE， PKC， Toll-like receptor （TLR）， COL， and GLO-1 was detected using real-time quantitative PCR （Real-time PCR）. Serum levels of aspartate aminotransferase （AST）， alanine aminotransferase （ALT）， creatinine （CREA）， urea （UREA）， interleukin-6 （IL-6）， and tumor necrosis factor （TNF）-α were measured by enzyme-linked immunosorbent assay （ELISA）. ResultsCompared with the normal group， the model group showed significantly increased fasting blood glucose （P<0.01）， decreased body weight and mechanical pain threshold （P<0.01）， and elevated serum AST， ALT， CREA， UREA， IL-6， and TNF-α levels （P<0.01）. The expression of RAGE， AGE， and PKC in the sciatic nerve was significantly increased （P<0.01）， while COL expression was decreased （P<0.01）. The mRNA expression of TLR， RAGE， and PKC was upregulated （P<0.01）， whereas COL and GLO-1 mRNA levels were downregulated （P<0.01）. Histological examination showed irregular nerve morphology， axonal alterations， and myelin degeneration. Compared with the model group， fasting blood glucose levels in the Tangbikang dry paste high-dose group at all time points and in the medium-dose group at weeks 4 and 16 were significantly reduced （P<0.05， P<0.01）. No significant changes in body weight were observed across all Tangbikang dose groups. The mechanical pain threshold was elevated at different time points after administration in all Tangbikang groups （P<0.05， P<0.01）. Serum IL-6 and TNF-α levels were decreased in all dose groups （P<0.05， P<0.01）. The expression of RAGE， AGE， and PKC in the sciatic nerve was reduced （P<0.01）， while COL expression was increased （P<0.01）. The mRNA expression of TLR， RAGE， and PKC was downregulated （P<0.01）， whereas GLO-1 mRNA expression was upregulated （P<0.05， P<0.01）. Additionally， COL mRNA expression was significantly increased in the low- and high-dose groups （P<0.01）. Pathological changes in the sciatic nerve were milder in all Tangbikang groups compared to the model group. ConclusionTangbikang dry paste significantly improves DPN， and its mechanism may be associated with the regulation of the GLO-1/AGE/RAGE signaling pathway.

This article aims to summarize the history, present opportunities and new challenges, and explore the experience of esophageal cancer prevention and treatment in Linxian (referred to as the “Linxian experience”), providing reference and guidance to cancer prevention and treatment research in China.

Objective: To analyze the association between different sleep statuses and overweight/obesity among primary school students, so as to provide a basis for the development of childhood overweight and obesity prevention and control strategies. Methods: In November 2023, a total of 3 391 primary school students of grade 1-6 from seven schools in Baoan District, Shenzhen, were surveyed by questionnaires and physical examinations by using multistage cluster sampling. The Logistic regression analysis was used to explore the association between primary school students sleep status and overweight/obesity. Results: The detection rate of overweight/obesity in primary school students was 22.59%, the detection rate of overweight/obesity in boys (27.04%) was higher than that in girls (17.44%), the only child (25.81%) had higher rates than nononly child (21.76%), and the differences were statistically significant (χ2=51.48, 5.98, P＜0.05). Multivariate Logistic regression analysis showed that, after controlling for confounders, primary school students weekend nighttime sleep duration (OR=0.83, 95%CI=0.75-0.91), weekly average nighttime sleep duration (OR=0.76,95%CI=0.64-0.89), and weekend compensated sleep duration (OR=0.89,95%CI=0.81-0.97) were negatively associated with the risk of developing overweight/obesity (P＜0.05). Compared with to primary school students with school days nap durations <0.5 h, those whose napped for 0.5-＜1 h and ≥1 h on school days had a 20% (OR=1.20, 95%CI=1.02-1.42) and 37% (OR=1.37, 95%CI=1.02-1.83) increased risk of overweight/obesity, respectively (P＜0.05). Conclusions Increasing weekend nighttime sleep duration, average weekly nighttime sleep duration, and weekend compensatory sleep duration can reduce the risk of overweight and obesity in primary school students. School days nap duration is a risk factor for overweight/obesity among primary school students.

Objective: To investigate the efficacy of interpersonal synchronous intervention on improving social behavioral deficits in children with autism spectrum disorder (ASD), in order to provide effective guidance for optimizing social intervention programs for ASD children. Methods: From September 2022 to March 2023, 84 ASD children aged 7-12 years were recruited from the Children and Adolescents Mental Health Medical Center of Inner Mongolia Autonomous Region Mental Health Center. The test subjects were randomly divided into an intervention group (42 cases) and a control group (42 cases). A 7month social interactive game intervention plan was implemented in the intervention group, with an average of 2 times per week, each lasting 70 minutes, for a total of 56 interventions; the control group only participates in routine social activites such as daily communication and cooperation. And tests were conducted on communication behavior indicators (language expression, language comprehension, and cognitive speaking) and maladaptive behavior indicators (action characteristics, emotional expression, and social communication) of two groups of ASD children before and after intervention, and the differences in various social behavior indicators between the two groups of ASD children before and after intervention were compared through paired sample ttest. Results: Before the intervention, there were no significant differences in language expression, language understanding and cognitive oral scores of children with ASD between the intervention and control groups (t=1.43, 1.65, 1.67, P>0.05). The language expression (76.29±2.34) and cognitive speaking (84.24±2.13) scores of the intervention group before intervention were lower than those after intervention (79.28±3.16, 88.39±2.35) (t=-4.17, -4.66), and the language understanding score (85.64 ± 2.30) was higher than that after intervention (83.33±1.28) (t=5.41)(P<0.05). Before intervention, there were no statistically significant differences in non adaptive behavior factors (motor characteristic, emotional expression, and social communication)between groups (t=1.05, 1.46, 1.69, P>0.05). After intervention, the intervention group had higher scores in motor characteristics (79.55±3.32), emotional expression (73.20±3.21), and social communication (78.22±4.05) compared to the control group (72.24±3.43, 69.33±4.18, 76.21±3.14) (t=7.10, 5.51, 4.24, P<0.05). Conclusion The interpersonal synchronous intervention program has shown good improvement in the treatment of social behavior disorders in children with ASD.

The shaoyang meridian is an important pivot between the internal organs and meridians system， with the functions of regulating qi and blood， balancing yin and yang， and coordinating the ascending and descending movement of qi. Dysfunction of the shaoyang pivot can lead to spleen and kidney deficiency， impaired liver and gallbladder qi regulation， and stagnation of qi and blood. It is believed that the onset and progression of Crohn's disease are closely related to shaoyang pivot dysfunction， with the core pathogenesis characterized by shaoyang disharmony， spleen deficiency， dampness retention， and blood stasis. Based on this understanding， the treatment principle centers on harmonizing the shaoyang pivot， supplemented by methods such as warming and nourishing the spleen and stomach， tonifying shaoyang， and soothing the liver and benefiting the gallbladder. Acupuncture is employed to target key acupoints along the shaoyang meridian to restore its regulatory functions， improve spleen and stomach transformation and transportation， facilitate liver and gallbladder qi flow， and promote the circulation of qi and blood. This provides a practical therapeutic approach for acupuncture-based treatment of Crohn's disease.

AIM: To compare the effects of different nucleus chopping methods on the central corneal thickness, corneal endothelial cell(CEC)count and tear inflammatory indicators in patients with hard nucleus cataract.METHODS: Retrospective study. Totally 89 patients(89 eyes)with hard nucleus cataract who treated in our hospital were included from January 2020 to December 2022. According to different intraoperative nucleus chopping methods, the patients were divided into reverse prechop group(46 eyes)and phaco-chop group(43 eyes). The total effective rate of surgery and visual acuity recovery were compared between the two groups. Corneal related indicators(central corneal thickness, CEC count, CEC area), tear inflammatory indicators and tear film function [tear film break-up time(BUT), Chinese Dry Eye Questionnaire(CDEQ), Schirmer Ⅰ test(SⅠt)] were observed before and after surgery in both groups, and the degree of corneal edema was evaluated.RESULTS: The effective phaco time, phaco energy and cumulative complex energy parameters in the phaco-chop group were longer or higher than those in the reverse prechop group(P<0.05). The macular retinal thickness in the reverse prechop group at 7 d and 1 mo after surgery was thinner than that in the phaco-chop group, the central corneal thickness at 3 and 7 d after surgery was also thinner than that in the phaco-chop group, the CEC count at 3 mo after surgery was more than that in the phaco-chop group, the CEC loss rate was lower than that in the phaco-chop group, and the CEC area at 3 mo after surgery was smaller than that in the phaco-chop group(P<0.05). The levels of tear TNF-α and IL-6 at 7 d and 1 mo after surgery in the reverse prechop group were lower than those in the phaco-chop group(P<0.05). The BUT at 1 and 3 mo after surgery was longer in the reverse prechop group than that in the phaco-chop group(P<0.05). The CDEQ score in the reverse prechop group was lower than that in the phaco-chop group at 1 and 3 mo after surgery(P<0.05). The SⅠt at 1 and 3 mo after surgery was higher in the reverse prechop group compared with that in the phaco-chop group(P<0.05). The degree of corneal edema at 1 d after surgery was milder in the reverse prechop group than that in the phaco-chop group(P<0.05). CONCLUSION: Compared with phaco-chop, the application of reverse-chopper prechop combined with phacoemulsification can better reduce the ultrasonic energy in the treatment of hard nuclear cataract, and it is more conducive to reducing the postoperative inflammatory degree, improving the tear film function and relieving the corneal edema degree.

AIM: To investigate the efficacy of small-incision horizontal space nuclear splitting surgery and phacoemulsification combined with regional refractive multifocal intraocular lens(MIOL)implantation in the treatment of hard nuclear cataract.METHODS:A retrospective analysis was performed for 288 patients(288 eyes)with hard nuclear cataract who admitted to our hospital from January 2022 to December 2023, and they were divided into control group(144 eyes treated with phacoemulsification and regional refractive MIOL)and observation group(144 eyes treated with small-incision horizontal space nuclear splitting surgery and regional refractive MIOL)according to different treatment methods. The operation time, pre- and post-operative best corrected visual acuity, astigmatism, central corneal thickness, corneal endothelial density, tear film function, and complications were compared between the two groups.RESULTS:There was no difference in operation time between the two groups(P>0.05). There was no difference in the preoperative and 3 mo postoperative best corrected visual acuity(all P>0.05), and the best corrected visual acuity of the two groups at 3 mo postoperatively was improved compared with the preoperative level(all P<0.05). There were differences in central corneal thickness, corneal endothelial density and astigmatism between the two groups at 1 wk and 3 mo after surgery(all P<0.05). There were differences in breakup time(BUT)and ocular surface disease index(OSDI)scores between the two groups at 1 wk after surgery(all P<0.001), and the incidence of complications in the observation group(4.2%)was significantly lower than that in the control group(18.1%; P<0.001).CONCLUSION:Both surgical methods can effectively treat patients with hard nuclear cataracts, and small-incision horizontal space nuclear splitting surgery combined with regional refractive MIOL implantation has less corneal damage and fewer complications.
