Objective To investigate the efficacy of preoperative nebulized indocyanine green (ICG)-assisted thoracoscopic anatomical lesion resection (TALR) in treating pediatric congenital pulmonary airway malformation (CPAM). Methods A retrospective analysis was conducted on clinical data of 45 children with CPAM who underwent thoracoscopic surgery at the Third Affiliated Hospital of Zhengzhou University between June 2023 and March 2025. The patients were divided into an ICG group (preoperative nebulized ICG 0.5 mg/kg+TALR) and a non-ICG group (TALR under white light), with perioperative and postoperative recovery parameters compared between groups. Results A total of 45 children [22 males, 23 females; median age 7.4 (1.1-75.0) months] were enrolled. The ICG group (n=22) and non-ICG group (n=23) both achieved uneventful recoveries. Compared to the non-ICG group, the ICG group demonstrated significantly shorter surgical duration [91.3 (38.0-144.0) min vs. 100.0 (50.0-175.0) min, P=0.032], reduced intraoperative blood loss [3.0 (2.0-10.0) mL vs. 5.0 (1.0-10.0) mL, P=0.049], shorter postoperative drainage duration [2.7 (1.9-3.9) d vs. 3.4 (1.8-19.9) d, P=0.003], and shortened hospital stay [4.6 (2.9-9.8) d vs. 5.0 (3.9-21.5) d, P=0.013]. Residual lesions occurred in 2 patients from the non-ICG group but none in the ICG group. Intragroup comparisons revealed significant improvements in ratio of time to peak tidal expiratory flow to expiratory time, ratio of volume to peak tidal expiratory flow to expiratory volume, and tidal volume per kilogram after surgery in both groups (P<0.05), though intergroup differences showed no statistical significance (P>0.05). Conclusion Preoperative nebulized ICG administration facilitates lesion identification in CPAM, reduces technical difficulty of TALR, enhances therapeutic outcomes, and provides valuable assistance for performing TALR procedures.

Objective To observe the value of immediate CT-guided small negative pressure thoracic drainage for pneumothorax after percutaneous lung biopsy(PTLB).Methods Totally 172 patients of unilateral pneumothorax after PTLB were retrospectively enrolled,including 83 patients underwent immediate CT-guided small negative pressure(about 30 mmHg)thoracic drainage after PTLB(group A)and 89 patients underwent bedside closed thoracic drainage after PTLB(group B).Clinical data before treamtent,degree of pneumothorax,the duration of catheterization,pain degree during catheterization(visual analogue scale[VAS]),blood oxygen saturation after treatment,the ratio of immediate relief of clinical symptoms,duration of drainage retention,duration of hospitalization after treatment and the occurrence of pleural reaction were compared between groups.Results Drainage went smoothly in both groups.No significant difference of clinical data before treatment nor pneumothorax degree was found between groups(all P＞0.05).Compared with those in group B,the duration of catheterization was shorter,and pain degree was lower during drainage in group A(both P＜0.001).After drainage,blood oxygen saturation and the proportion of immediate relief of clinical symptoms in group A were both higher than those in group B,while the duration of drainage retention and hospitalization were both shorter in group A than those in group B(all P＜0.001).Pleural reaction occurred in 2 patients in group A and 1 patient in group B,and no significant difference of pleural reaction was detected between groups(P=0.520).Conclusion Immediate CT-guided small negative pressure thoracic drainage was effective and safe for pneumothorax after PTLB.

Background::Psychological stress has been reported to be a potential risk factor for hypertension among females, but it remains unclear whether spousal chronic stress levels alter the risk of hypertension among women. We examined the associations between stress within the family and hypertension among married women.Methods::Reproductive-aged women who were planning for pregnancy and their husbands were recruited from the National Free Pre-pregnancy Checkup Projects (NFPCP) across 31 provinces in China in 2016 and 2017. Perceived stress of wives or husbands was measured with a 5-point Likert-type scale, and assessed from three domains: work/life-related stress, economic stress, and overall stress. Multivariable-adjusted logistic regression models were used to assess the associations between stress status and the prevalence of hypertension.Results::Of 10,027,644 couples, 261,098 (2.60%) women had hypertension. The results showed that higher stress levels among themselves or their husbands were associated with a higher prevalence of hypertension in women ( Pfor trend <0.001). Compared with non-stressed participants, female participants with the highest stress themselves were at a greater risk of hypertension, with adjusted odds ratio (OR) of 1.31 (95% confidence interval [CI]: 1.25-1.37); and compared with participants whose husbands had no stress, those whose husbands had the highest stress level were at a higher risk of hypertension with adjusted OR of 1.24 (95% CI: 1.20-1.29). Moreover, compared with non-stressed status for both couples, only-wife-stressed, only-husband-stressed, and both-stressed couples were found to be significantly associated with increased risks of wives’ hypertension, with adjusted ORs of 1.28 (95% CI: 1.25-1.31), 1.19 (95% CI: 1.17-1.21), and 1.28 (95% CI: 1.26-1.31), respectively. Conclusion::Moderate to severe stress in both spouses might be associated with female hypertension prevalence, which highlights the importance of paying attention to the psychological stresses of couples within the family.

Chaperone-mediated autophagy (CMA) is a lysosome-dependent selective degradation pathway implicated in the pathogenesis of cancer and neurodegenerative diseases. However, the mechanisms that regulate CMA are not fully understood. Here, using unbiased drug screening approaches, we discover Metformin, a drug that is commonly the first medication prescribed for type 2 diabetes, can induce CMA. We delineate the mechanism of CMA induction by Metformin to be via activation of TAK1-IKKα/β signaling that leads to phosphorylation of Ser85 of the key mediator of CMA, Hsc70, and its activation. Notably, we find that amyloid-beta precursor protein (APP) is a CMA substrate and that it binds to Hsc70 in an IKKα/β-dependent manner. The inhibition of CMA-mediated degradation of APP enhances its cytotoxicity. Importantly, we find that in the APP/PS1 mouse model of Alzheimer's disease (AD), activation of CMA by Hsc70 overexpression or Metformin potently reduces the accumulated brain Aβ plaque levels and reverses the molecular and behavioral AD phenotypes. Our study elucidates a novel mechanism of CMA regulation via Metformin-TAK1-IKKα/β-Hsc70 signaling and suggests Metformin as a new activator of CMA for diseases, such as AD, where such therapeutic intervention could be beneficial.

Objective:To investigate the long-term effects of porcine small intestinal submucosa (SIS) biologic mesh in open Lichtenstein tension-free hernia repair.Methods:The prospective randomized controlled study was conducted. The clinical data of 76 patients with unilateral inguinal hernia who underwent open Lichtenstein tension-free hernia repair in 2 medical centers (52 cases in Tianjin People′s Hospital and 24 cases in China-Japan Friendship Hospital) from August 2013 to March 2014 were selected. Based on random number method, patients were allocated into two groups. Patients undergoing Lichtenstein tension-free hernia repair using Biodesign Surgisis mesh were allocated into control group, and patients undergoing Lichtenstein tension-free hernia repair using SIS biologic mesh were allocated into experiment group. Observa-tion indicators: (1) grouping situations of the enrolled patients; (2) postoperative long-term effects. Follow-up was conducted using telephone interview, text message or mail to detect hernia recurrence or death due to other reasons as the end-point event of patients up to December 2019. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented by M (range), and comparison between groups was conducted using the Mann-Whitney U test. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Results:(1) Grouping situations of the enrolled patients: a total of 76 patients were selected for eligibility. There were 38 cases in the control group and the experiment group, respectively. The number of males and females, age, body mass index, cases with intraspinal anesthesia or local anesthesia (anesthesia method), cases with inguinal hernia on the left side or on the right side, cases classified as type Ⅰ, Ⅱ, Ⅲ, Ⅳ or Ⅴ of Gilbert classification, operation time of the control group were 35, 3, (56±15)years, (23.0±2.0)kg/m 2, 22, 16, 16, 22, 9, 16, 0, 11, 2 and (49±15)minutes, respectively. The above indicators of the experiment group were 34, 4, (54±13)years, (22.9±2.2)kg/m 2, 17, 21, 14, 24, 9, 21, 1, 7, 0, and (53±21)minutes, respectively. There was no significant difference in the above indicators between the two groups ( χ2=0.157, t=0.532, 0.367, χ2=1.317, 0.220, Z=-0.315, t=-0.765, P>0.05). (2) Post-operative long-term effects: 35 patients of the control group were followed up for (68.8±2.7)months, 4 cases of which died due to other reasons, 1 case had hernia recurrence, 1 case had chronic pain and no foreign body sensation and postoperative infection occurred. Thirty-one patients of the experiment group were followed up for (68.8±2.7)months, with no death or above complications. There was no significant difference in hernia recurrence or chronic pain between the two groups ( P>0.05). Conclusion:The long-term effects of biological mesh in open Lichtenstein tension-free hernia repair is satisfactory and there is no difference in the long-term effects between the domestic SIS biological mesh and Biodesign Surgisis mesh.

Objective:To explore the association between abnormal thyroid stimulating hormone (TSH) and elevated blood pressure among females of child-bearing potential.Methods:A total of 294 674 females of child-bearing age who participated in pre-pregnancy health examination in Shenzhen from 2013 to 2019 were selected. Demographic characteristics, blood pressure, TSH, fasting blood glucose and other indexes were collected. Multivariate logistic regression model was used to analyze the association between abnormal TSH levels and elevated blood pressure (including prehypertension and hypertension).Results:This study showed that females of child-bearing potential with prehypertension and hypertension accounted for 21.77% and 2.41%, respectively. Compared with females of child-bearing potential with normal TSH, the risk of prehypertension and hypertension increased by 34.0% ( OR=1.340, 95% CI 1.248-1.438) and 59.6% ( OR=1.596, 95% CI 1.301-1.938) among those with decreased TSH, respectively, whereas the risk of prehypertension and hypertension increased by 13.6% ( OR=1.136, 95% CI 1.076-1.198) and 38.0% ( OR=1.380, 95% CI 1.198-1.581) among those with elevated TSH, respectively. Subgroup analysis showed that abnormal TSH levels in most subgroups, such as age, ethnicity, educational level, occupation, spouse smoking, alcohol drinking, body mass index, and fasting blood glucose, were associated with the risk of elevated blood pressure. Heterogeneity test showed that the association between decreased TSH and elevated blood pressure was higher in females with high school and below or alcohol drinking, and the association between elevated TSH and elevated blood pressure was higher in females with college/bachelor′s degree and above or non-smoking spouse. Conclusion:There is a significant association between abnormal TSH levels and the risk of prehypertension and hypertension in females of child-bearing potential, and the association should be explored with stratified educational level, alcohol drinking, and spouse smoking status.

Objective: To analyze the clinical characteristics of cases of novel coronavirus pneumonia and a preliminary study to explore the relationship between different clinical classification and liver damage. Methods: Consecutively confirmed novel coronavirus infection cases admitted to seven designated hospitals during January 23, 2020 to February 8, 2020 were included. Clinical classification (mild, moderate, severe, and critical) was carried out according to the diagnosis and treatment program of novel coronavirus pneumonia (Trial Fifth Edition) issued by the National Health Commission. The research data were analyzed using SPSS19.0 statistical software. Quantitative data were expressed as median (interquartile range), and qualitative data were expressed as frequency and rate. Results: 32 confirmed cases that met the inclusion criteria were included. 28 cases were of mild or moderate type (87.50%), and four cases (12.50%) of severe or critical type. Four cases (12.5%) were combined with one underlying disease (bronchial asthma, coronary heart disease, malignant tumor, chronic kidney disease), and one case (3.13%) was simultaneously combined with high blood pressure and malignant tumor. The results of laboratory examination showed that the alanine aminotransferase (ALT), aspartate aminotransferase (AST), albumin (ALB), and total bilirubin (TBil) for entire cohort were 26.98 (16.88 ~ 46.09) U/L and 24.75 (18.71 ~ 31.79) U/L, 39.00 (36.20 ~ 44.20) g/L and 16.40 (11.34- ~ 21.15) mmol/L, respectively. ALT, AST, ALB and TBil of the mild or moderate subgroups were 22.75 (16.31- ~ 37.25) U/L, 23.63 (18.71 ~ 26.50) U/L, 39.70 (36.50 ~ 46.10) g/L, and 15.95 (11.34 ~ 20.83) mmol/L, respectively. ALT, AST, ALB and TBil of the severe or critical subgroups were 60.25 (40.88 ~ 68.90) U/L, 37.00 (20.88 ~ 64.45) U/L, 35.75 (28.68 ~ 42.00) g/L, and 20.50 (11.28 ~ 25.00) mmol/L, respectively. Conclusion The results of this multicenter retrospective study suggests that novel coronavirus pneumonia combined with liver damage is more likely to be caused by adverse drug reactions and systemic inflammation in severe patients receiving medical treatment. Therefore, liver function monitoring and evaluation should be strengthened during the treatment of such patients.
