AIM: To observe the preoperative and postoperative clinical efficacy of comprehensive dry eye treatment in cataract patients complicated with diabetes mellitus, with a focus on comparing the differences between the two groups in terms of postoperative dry eye symptoms, tear film function, visual recovery, and complication rates, aiming to provide an effective protocol for the perioperative management and long-term prognosis improvement in this patient population.METHODS:Patients diagnosed with both cataract and diabetes mellitus and presenting with varying degrees of dry eye symptoms, scheduled for cataract surgery at the hospital from May 2023 to December 2024, were enrolled as study subjects. They were divided into two groups using a random number method: the control group received sodium hyaluronate eye drops alone, and the experimental group underwent comprehensive preoperative dry eye treatment(sodium hyaluronate eye drops+warm compress+meibomian gland cleaning and massage+Chinese herbal fumigation+health guidance). Tear film breakup time(BUT), corneal fluorescein staining(FL), Ocular Surface Disease Index(OSDI)score, tear meniscus height(TMH), and non-invasive first tear film breakup time(NIBUT)were compared between the two groups before and after 4 wk of treatment. Meibomian gland loss, tear film lipid layer thickness, and basic ocular symptoms were also assessed.RESULTS:This study included 60 eyes of 60 patients, with a control group of 30 eyes of 30 patients(aged 56.24±10.24 y, 13 males and 17 females)and an experimental group of 30 eyes of 30 patients(aged 58.01±9.79 y, 15 males and 15 females).After 4 wk of preoperative treatment, the BUT in the experimental group increased from 4.09±1.13 s to 10.35±1.46 s, and from 4.15±1.05 s to 8.26±1.36 s in the control group, showing a significant intergroup difference(t=5.737, P<0.001). The FL score in the experimental group decreased from 6.83±0.46 points to 2.86±0.38 points, whereas in the control group it decreased from 6.79±0.39 points to 5.32±0.43 points(t=23.480, P<0.001). After 4 wk of treatment, the NIBUT in the experimental group increased from 5.19±1.12 s to 9.36±1.47 s, compared to an increase from 5.21±1.04 s to 7.18±1.25 s in the control group(t=6.188,P<0.001). The proportion of patients with a thin tear film lipid layer was significantly higher in the experimental group than in the control group(all P<0.01). Ocular clinical symptoms decreased after treatment in both groups, with the experimental group showing lower scores than the control group(all P<0.001).CONCLUSION:Preoperative comprehensive dry eye treatment can multi-dimensionally improve dry eye symptoms and tear film stability in cataract patients with diabetes mellitus, providing an effective strategy for the perioperative management of cataract patients.

The prevalence of dry eye among children has been progressively increasing each year; however, clinical diagnosis remains challenging due to the unique physiological attributes of the pediatric tear film functional unit, as well as symptoms that are often atypical and clinical signs that differ from those seen in adults. In healthy children, tear secretion is generally greater, the meibomian gland structure is typically more intact, and the meibum composition and physicochemical properties are more favorable for the maintenance of tear film stability. Compared to adults, the etiology of pediatric dry eye is more frequently associated with meibomian gland dysfunction, allergic ocular conditions, orthokeratology lens wear, environmental influences, such as growing screen time, and systemic disorders. Affected children frequently exhibit non-specific symptoms such as excessive blinking or rubbing of the eyes, which may be overlooked due to their limited ability to verbalize discomfort. Clinical signs can include conjunctival hyperemia, decreased tear meniscus height, and corneal epithelial punctate lesions, though these tend to be milder or less distinct compared with adults. Diagnostic requires the use of age-appropriate tear metrics, such as the Schirmer test and tear film breakup time, alongside ocular surface evaluation, with particular attention to features specific to children that distinguish it from dry eye in adults. Going forward, it is essential to establish and validate pediatric-specific diagnostic criteria to improve ocular surface health and maximize visual quality in this vulnerable population.

ObjectiveTo investigate the therapeutic effects and mechanisms of modified Huangqi Jianzhong decoction （HQJZ） on gastric precancerous conditions （GPC）. MethodsIn the cell experiment， human gastric mucosal epithelial cells underwent malignant transformation induced by N-methyl-N′-nitro-N-nitrosoguanidine （MNNG） for the modeling of GPC （MC cells）. The cells were allocated into four groups： control ， model， low-dose HQJZ （HQJZ-L）， and high-dose HQJZ （HQJZ-H）. The control and model groups were cultured with the complete medium， while HQJZ-L and HQJZ-H groups received additional interventions with HQJZ at low （0.5 g·L^-1） and high （1.0 g·L^-1） doses， respectively. Cell counting kit-8 （CCK-8） assay was used to evaluate cytotoxicity， Transwell assay to assess cell invasion， Annexin V-FITC/PI staining to detect apoptosis， immunofluorescence assay to analyze reactive oxygen species （ROS） expression and mitochondrial autophagy， and Western blot to verify expression of proteins in key pathways. In the animal experiment， the GPC model was established in healthy BALB/c mice through MNNG induction. Twenty-four mice were allocated into four groups： control， model， HQJZ-L， and HQJZ-H. Control and model groups received normal saline （10 mL·kg^-1·d^-1） orally， while HQJZ-L and HQJZ-H groups were administrated with low-dose （6.24 g·kg^-1·d^-1） and high-dose （12.48 g·kg^-1·d^-1） HQJZ， respectively. After treatment， hematoxylin‑eosin （HE） staining and AB-PAS staining were performed to observe histopathological changes in the gastric tissue. Immunofluorescence assay was used to detect reactive oxygen species （ROS） and microtubule-associated protein 1 light chain 3 （LC3） levels in the gastric mucosa， TdT-mediated dUTP nick-end labeling （TUNEL） staining to assess apoptosis rates， and Western blotting and immunohistochemistry （IHC） to analyze the expression levels of Ki67， proliferating cell nuclear antigen （PCNA）， and foxhead box O3 （FoxO3）. ResultsCell viability assays showed that HQJZ dose-dependently reduced MC cell viability compared with the control group （P<0.05， P<0.01）. Transwell assays revealed that the model group exhibited enhanced cell invasion compared with the control group （P<0.05）. Compared with the model group， HQJZ treatment attenuated the cell invasion （P<0.05）. Gastric mucosal pathology in mice demonstrated that compared with the control group， the model group showed elevated HE and AB-PAS pathological scores （P<0.05）， while HQJZ treatment reduced these scores （P<0.05）. Transmission electron microscopy revealed increased mitochondrial number and volume in the model group compared with the control group. HQJZ treatment resulted in abnormal mitochondrial structure and significant alterations in rough endoplasmic reticulum morphology and distribution， presenting as dilated and hollow forms. Mitochondrial and apoptosis assessments indicated that compared with the control group， the model group exhibited enhanced Mito Tracker Green fluorescence （P<0.05）， no significant change in DCFH-DA fluorescence， Mito Tracker Red CMXRos fluorescence， ROS immunofluorescence， or malondialdehyde （MDA） level， increased GSH level （P<0.05）， enhanced LC3 fluorescence （P<0.05）， no significant change in apoptosis rate， and elevated ATP content in cells and mouse serum （P<0.05）. Compared with the model group， HQJZ treatment reduced Mito Tracker Green fluorescence （P<0.05）， increased DCFH-DA fluorescence， Mito Tracker Red fluorescence， MDA level， LC3 fluorescence， and apoptosis rate （P<0.05）， and decreased cellular ATP content （P<0.05）. The HQJZ-L group showed no significant change in ROS immunofluorescence or GSH level， whereas the HQJZ-H group demonstrated enhanced ROS immunofluorescence and glutathione （GSH） level （P<0.05）. Immunohistochemistry and Western blotting revealed that compared with the control group， the model group exhibited increased numbers of PCNA- and Ki67-positive cells （P<0.05） and elevated protein levels of FoxO3， sirtuin 1 （SIRT1）， and B-cell lymphoma 6 （Bcl-6） （P<0.05）. HQJZ treatment reduced the numbers of PCNA- and Ki67-positive cells （P<0.05） and lowered the protein levels of FoxO3， SIRT1， and Bcl-6 （P<0.05）. ConclusionHQJZ alleviates the progression of gastric precancerous lesions by regulating mitochondrial function via the FoxO3/ROS pathway and promoting apoptosis of GPC-malignant cells.

Objective To investigate the effect of different intraoperative oxygen concentrations on myocardial injury after noncardiac surgery(MINS)in patients with coronary heart disease undergoing laparoscopic surgery.Methods A total of 76 patients with coronary heart disease scheduled for laparoscopic surgery between January and December 2024 were randomly assigned to group L(FiO2=0.3,n=39)or group H(FiO2=0.8,n=37).In the group L,if intraoperative oxygen saturation fell below 92%,FiO2 was increased incrementally by0.03-0.1 as required.MINS was defined as postoperative high-sensitivity troponin T(hs-TnT)levels>65 ng/L,or 20 ng/L0.05).Conclusion Maintaining a lower intraoperative oxygen concentration(FiO2=0.3)in patients with coronary heart disease undergoing laparoscopic surgery reduces early postoperative myocardial injury markers and may help mitigate MINS.

Objective:To explore the association between cardiometabolic multimorbidity(CMM), the number of cardiometabolic diseases(CMD)and mild cognitive impairment(MCI)among the older adults in urban communities.Methods:Based on the baseline data of the Hubei Memory and Aging Cohort Study(HMACS)from 2018 to 2023, CMM was defined as the coexistence of two or more CMDs(Type 2 diabetes, stroke and ischemic heart disease). Multivariate logistic regression was employed to examine the association between CMM, the number of CMDs and the prevalence of MCI, as well as subgroup heterogeneity.Results:This study included 6 113 urban participants aged ≥65 years(55.6% were female; mean age 71.9±5.7 years). The prevalence of MCI was 19.3%, with an increasing trend observed as the number of CMD increased(17.7%, 20.5%, 24.6%, 28.3%). After adjusting for all variables, a significant association was observed between CMM group and the prevalence of MCI( OR: 1.24, 95% CI: 1.01-1.52)compared with the non-CMM group.As the number of CMD increased, the prevalence of MCI increased( Ptrend=0.011), but the association was only significant in the group with two CMDs.Subgroup analyses revealed that in males( OR: 1.48, 95% CI: 1.10-2.00), those with more than 9 years of education( OR: 1.52, 95% CI: 1.15-2.02), and those with hypertension( OR: 1.33, 95% CI: 1.05-1.67), CMM was significantly associated with MCI, and the association with MCI increased significantly with the increase in the number of CMDs(all Pfor trend <0.05). Conclusions:Among urban community-dwelling older adults aged ≥65 years in China, CMM and the cumulative number of CMDs are significantly associated with an increase of MCI, particularly in males, those with higher education levels, and those with hypertension.In the future, the need for enhanced MCI screening for CMM patients should be strengthened, and targeted prevention and control of cognitive impairment should be implemented for high-risk populations.

Objective:To understand the characteristics of new infections in the newly reported HIV-1 infected population in Luzhou, to find out the characteristics of the high-risk population, which may provide a basis for developing precise prevention and control measures locally.Methods:HIV-1 LAg Avidity EIA test was applied for newly reported cases in Luzhou from 2018 to 2021. The chi-square test was used for univariate analysis, logistic regression model for multivariate analysis, and spatial autocorrelation and hotspot analysis were applied to explore the spatial distribution characteristics of new infections in Luzhou city.Results:A total of 4 494 cases reported in the odd-numbered months were selected for testing, with 673 newly infected cases and the proportion of newly infected cases was 14.98%. Newly infected cases were predominantly male (472/673, 70.13%), married (335/673, 49.78%), heterosexual transmission (621/673, 92.27%), age>50 years (520/673, 77.27%), and junior high school or lower education (599/673, 89.00%). The proportion of new infections in each year were 11.74% (129/1 099), 17.11% (247/1 444), 13.57% (154/1 134) and 17.50% (143/817), respectively, with a statistically significant difference ( χ2=20.024, P<0.001) and an upward trend ( χ2=5.997, P=0.014). There were statistically significant differences in different transmission routes, gender, education level, occupation, sample source and residence (all P<0.05). Logistic regression analysis showed that gender, marital status, transmission route, current address, and sample source were all influencing factors for new infections. There are spatial autocorrelation characteristics of new case incidence in 2018 and 2021, hotspot areas gradually shifted from dispersed to relatively concentrated, with the number fluctuating with reported year. Conclusions:The proportion of new HIV-1 infections in Luzhou is relatively low throughout the province, but it is on the rise. The proportion of new infections is higher among youth, students, homosexual transmission, and retired persons. Attention should be focused on hotspot areas and routine surveillance and testing of key populations in hotspot areas should be strengthened.

Objective:To understand the coverage and information consistency rate of National Immunization Program (NIP) vaccines among children born during 2020-2021 in Zhejiang Province, Chongqing City, and Shanxi Province (3 provinces) of China .Methods:A simple random sampling method was used to randomly select 3 counties (districts) from each of the 3 provinces, 5 townships from each county (district), and 5 villages from each township. Vaccination information for seven NIP vaccines was collected for children born between 2020 and 2021 in each village. The vaccination coverage, timely coverage, and consistency rates between the survey data and the Immunization Planning Information System data were analyzed.Results:A total of 1 117 children were investigated. The vaccination coverage for each dose of NIP vaccine ranged from 99.10% to 100.00%, with those in Zhejiang Province, Chongqing City, and Shanxi Province ranging from 99.19% to 100.00%, 98.92% to 100.00%, and 99.20% to 100.00%, respectively. The timely coverage of each dose of NIP vaccine ranged from 89.79% to 99.82%, with those in Zhejiang Province, Chongqing City, and Shanxi Province ranging from 94.09% to 99.73%, 89.52% to 99.73%, and 78.55% to 100.00%, respectively. The consistency rate of information on each dose of NIP vaccine ranged from 94.36% to 99.91%, with those in Zhejiang Province, Chongqing City, and Shanxi Province ranging from 97.85% to 99.73%, 98.92% to 100.00%, and 86.06% to 100.00%, respectively.Conclusions:Coverage of NIP vaccines was generally high among children born during 2020-2021 in the 3 provinces of China, but there were regional differences in the timely coverage of some vaccine doses and the vaccination information consistency rate. It is necessary to strengthen the timely vaccination of children's vaccine booster doses and optimize the management of vaccination services.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.
