Objective: To explore the association between CDKAL1 rs35261542, FAIM2 rs 3205718, and VGLL4 rs 2574704 polymorphisms with childhood obesity and related metabolic phenotypes to provide evidence for personalized prevention and management strategies. Methods: Based on the 2023 Long term Nutritional Health Effects of Early Childhood Nutrition Package Intervention project, the study enrolled 1 078 children aged 5-7 years from four counties in Henan (Songxian and Ruyang countries) and Guizhou (Guiding and Fuquan countries) provinces. Using BMI Z scores, 87 overweight and obese(OVOB) children were selected and matched by sex, age, and BMI Z score with 117 normal weight controls. Participants were further stratified into four metabolic phenotype groups: metabolically healthy normal weight (MHNW, n =51), metabolically unhealthy normal weight (MUNW, n =66), metabolically healthy obesity (MHO, n =31) and metabolically unhealthy obesity (MUO, n =56) based on four conventional cardiometabolic risk factor (CR) criteria. Data were collected through questionnaires, anthropometric measurements, serum biochemical tests, and KASP genotyping. The distribution of three genetic polymorphisms ( CDKAL1 rs35261542, FAIM2 rs3205718, VGLL4 rs 2574704) across metabolic subgroups was analyzed. Multivariate Logistic regression models assessed associations between these polymorphisms and obesity/metabolic phenotypes. Results: Multivariate Logistic regression analysis showed that Homozygous mutant AA genotype of CDKAL1 rs 35261542 was positively associated with OVOB( OR =3.63), MHO ( OR =11.04), MUO ( OR = 4.88 ) ( P <0.05). Homozygous TT genotype of FAIM2 rs 3205718 increased OVOB risk ( OR =4.44, P <0.05) but showed no association with metabolic phenotypes ( P >0.05). Homozygous mutant TT of VGLL4 rs 2574704 reduced the risks of MHO and MUO ( OR = 0.30, 0.24， P <0.05). Cumulative genetic effects analysis demonstrated carriers of 1 or 2 risk genotypes of rs 35261542 and rs 3205718 had progressively higher OVOB risk ( OR =2.53, 20.79), and the combination of rs 35261542 and rs 2574704 increased risks for both MHO ( OR =8.50) and MUO ( OR =5.00) ( P <0.05). Conclusions The AA genotype of rs 35261542 ( CDKAL1 ) positively correlates with childhood obesity and metabolic abnormalities. The TT genotype of rs 3205718 ( FAIM 2) increases obesity risk but not metabolic phenotypes. The TT genotype of rs 2574704 ( VGLL 4) shows protective effects against metabolic dysfunction. Risk genotypes exhibit dosedependent cumulative effects on obesity and metabolic outcomes.

Bronchial asthma （asthma for short） is a common clinical respiratory disease mainly characterized by chronic airway inflammation， with complicated pathogenesis and a long treatment cycle. It is lingering and difficult to be cured， and lack specific drugs. Oxidative stress is a new focus in the research on the pathogenesis of asthma and a potential key target for the treatment. Under physiological conditions， the oxidative and antioxidative systems in the body are in a dynamic balance， and the two antagonize each other to maintain normal life activities. In the case of asthma attack， oxidation products such as reactive oxygen species （ROS）， malondialdehyde （MDA）， and nitric oxide （NO） are produced excessively， while the content of antioxidants such as superoxide dismutase （SOD）， catalase （CAT）， and glutathione （GSH） is reduced. As a result， the oxidation exceeds the removal of oxidation products， which aggravates oxidative stress. In addition， the overproduction of ROS activates oxidative stress-related signaling pathways to produce pro-inflammatory factors， exacerbating inflammation， which leads to lung and airway tissue damage. In recent years， traditional Chinese medicine has garnering increasing attention because of the unique advantages in the treatment of asthma， especially in regulating redox balance， alleviating oxidative stress in asthma patients， and reducing inflammation. On the one hand， by inhibiting the mitogen-activated protein kinase （MAPK） and transcription factor （NF）-κB signaling pathways， traditional Chinese medicine can reduce the content of oxidation products and pro-inflammatory factors from the source. On the other hand， by activating the nuclear factor-erythroid 2-related factor 2 （NrF2） signaling pathway， traditional Chinese medicine can elevate the levels of antioxidant enzymes and enhance the antioxidant system to neutralize the excessive accumulation of oxidation products. Therefore， the adjustment of redox balance state by traditional Chinese medicine may be a new means and a new direction for the prevention and treatment of asthma in the future. This paper summarizes the oxidative stress-related pathways in the pathogenesis of asthma and reviews the latest research progress in the regulation of oxidative stress-related pathways by Chinese medicine extracts and prescriptions in the treatment of asthma， with a view to providing a fuller， more solid， and more scientific theoretical basis for the clinical and basic research on the prevention and treatment of asthma by traditional Chinese medicine.

OBJECTIVE: This study aimed to investigate the therapeutic effects of Xiaoyao San (XYS), a herbal medicine formula, on exercise capacity and liver mitochondrial metabolomics in a rat model of depression induced by chronic unpredictable mild stress (CUMS). METHODS: A total of 24 male SD rats were randomly divided into four groups: control group (C), CUMS control group (M), Venlafaxine positive treatment group (V), and XYS treatment group (X). Depressive behaviour and exercise capacity of rats were assessed by body weight, sugar-water preference test, open field test, pole test, and rotarod test. The liver mitochondria metabolomics were analyzed by using liquid chromatography-mass spectrometry (LC-MS) method. TCMSP database and GeneCards database were used to screen XYS for potential targets for depression, and GO and KEGG enrichment analyses were performed. RESULTS: Compared with C group, rats in M group showed significantly lower body weight, sugar water preference rate, number of crossing and rearing in the open field test, climbing down time in the pole test, and retention time on the rotarod test (P < 0.01). The above behaviors and exercise capacity indices were significantly modulated in rats in V and X groups compared with M group (P < 0.05, 0.01). Compared with C group, a total of 18 different metabolites were changed in the liver mitochondria of rats in M group. Nine different metabolites and six metabolic pathways were regulated in the liver mitochondria of rats in X group compared with M group. The results of network pharmacology showed that 88 intersecting targets for depression and XYS were obtained, among which 15 key targets such as IL-1β, IL-6, and TNF were predicted to be the main differential targets for the treatment of depression. Additionally, a total of 1 553 GO signaling pathways and 181 KEGG signaling pathways were identified, and the main biological pathways were AGE-RAGE signaling pathway, HIF-1 signaling pathway, and calcium signaling pathway. CONCLUSION XYS treatment could improve depressive symptoms, enhance exercise capacity, positively regulate the changes of mitochondrial metabolites and improve energy metabolism in the liver of depressed rats. These findings suggest that XYS exerts antidepressant effects through multi-target and multi-pathway.

The clinicopathological data of 102 patients with initially unresectable HCC who were admitted to the Third Affiliated Hospital of Naval Medical University from October 26,2015 to December 31,2022 were collected. There were 82 males and 20 females, aged 52(range,25?73)years. Of 102 patients, 72 cases undergoing PVE combined with TACE were set as the PVE+TACE group, and 30 cases undergoing PVE were set as the PVE group. Observation indicators: (1) surgical resection rate of secondary hepatectomy and increase of future liver remnant (FLR); (2) situations of secondary hepatectomy; (3) follow-up. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the independent sample t test. Measurement data with skewed distribution were represented as 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. Comparison of ordinal data was conducted using the Mann-Whitney U test. The Kaplan-Meier method was used to calculate survival rate and draw survival curve, and Log-Rank test was used for survival analysis. Results:(1) Surgical resection rate of secondary hepatectomy and increase of FLR. The surgical resection rate of secondary hepatectomy in the PVE+TACE group and the PVE group were 72.2%(52/72) and 53.3%(16/30), respectively, showing no significant difference between the two groups ( χ2=3.400, P>0.05). The surgical waiting time, increasing volume of FLR, growth rate of FLR in the 52 patients of PVE+TACE group receiving secon-dary hepatectomy were 20(range, 14?140)days, 140(range, 62?424)mL, 9.8(range, 1.5?26.5)mL/day, respectively. The above indicators in the 16 patients of PVE group receiving secondary hepatectomy were 16(range, 12?35)days, 160(range, 95?408)mL, 10.5(range, 1.2?28.0)mL/day, respectively. There was no significant difference in the above indicators between the 52 patients of PVE+TACE group and the 16 patients of PVE group ( Z=1.830, 1.498, 1.266, P>0.05). (2) Situations of secondary hepatectomy. The operation time, rate of tumor necrosis (>90%, 60%?90%,<60%), cases with complications ≥ grade Ⅲa in the 52 patients of PVE+TACE group receiving secondary hepatectomy were 200(range, 125?420)minutes, 8, 4, 40, 28, respectively. The above indicators in the 16 patients of PVE group receiving secondary hepatectomy were 170(range, 105?320)minutes, 0, 0, 16, 4, respectively. There were significant differences in the above indicators between the 52 patients of PVE+TACE group and the 16 patients of PVE group ( Z=2.132, ?2.093, χ2=4.087, P<0.05). (3) Follow-up. Sixty-eight patients who completed the surgery were followed up for 40(range, 10?84)months. The 1-, 3-, 5-year recurrence free survival rate in the 52 patients of PVE+TACE group receiving secondary hepatectomy were 73.0%, 53.3%, 35.4%, respectively. The above indicators in the 16 patients of PVE group were 62.5%, 37.5%, 18.8%, respectively. There was a significant difference in the recurrence free survival rate between the 52 patients of PVE+TACE group and the 16 patients of PVE group ( χ2=4.035, P<0.05). The 1-, 3-, 5-year overall survival rate in the 52 patients of PVE+TACE group receiving secondary hepatectomy were 82.5%, 61.2%, 36.6%, respectively. The above indica-tors in the 16 patients of PVE group receiving secondary hepatectomy were 68.8%, 41.7%,20.8%, respectively. There was a significant difference in the overall survival rate between the 52 patients of PVE+TACE group and the 16 patients of PVE group ( χ2=4.767, P<0.05). Conclusion:Compared with PVE, PVE+TACE as stage Ⅰ surgery can increase the surgical resection rate of secondary hepatec-tomy and the recurrence free survival rate of patients with initially unresectable HCC, prolong the long-term survival time, but not influence the growth rate of FLR.

Objective:To study the distribution and antibiotics resistance of the main pathogens of neonatal purulent meningitis in different regions of China.Methods:A retrospective descriptive clinical epidemiological study was conducted in children with neonatal purulent meningitis which admitted to 18 tertiary hospitals in different regions of China between January 2015 to December 2019. The test results of blood and cerebrospinal fluid, and drug sensitivity test results of the main pathogens were collected. The distributions of pathogenic bacteria in children with neonatal purulent meningitis in preterm and term infants, early and late onset infants, in Zhejiang Province and other regions outside Zhejiang Province, and in Wenzhou region and other regions of Zhejiang Province were analyzed. The chi-square test was used for statistical analysis.Results:A total of 210 neonatal purulent meningitis cases were collected. The common pathogens were Escherichia coli ( E. coli)(41.4%(87/210)) and Streptococcus agalactiae ( S. agalactiae)(27.1%(57/210)). The proportion of Gram-negative bacteria in preterm infants (77.6%(45/58)) with neonatal purulent meningitis was higher than that in term infants (47.4%(72/152)), and the difference was statistically significant ( χ2=15.54, P=0.001). There were no significant differences in the constituent ratios of E. coli (36.5%(31/85) vs 44.8%(56/125)) and S. agalactiae (24.7%(21/85) vs 28.8%(36/125)) between early onset and late onset cases (both P>0.05). The most common pathogen was E. coli in different regions, with 46.7%(64/137) in Zhejiang Province and 31.5%(23/73) in other regions outside Zhejiang Province. In Zhejiang Province, S. agalactiae was detected in 49 out of 137 cases (35.8%), which was significantly higher than other regions outside Zhejiang Province (11.0%(8/73)). The proportions of Klebsiella pneumoniae, and coagulase-negative Staphylococcus in other regions outside Zhejiang Province (17.8%(13/73) and 16.4%(12/73)) were both higher than those in Zhejiang Province (2.9%(4/137) and 5.1%(7/137)). The differences were all statistically significant ( χ2=14.82, 12.26 and 7.43, respectively, all P<0.05). The proportion of Gram-positive bacteria in Wenzhou City (60.8%(31/51)) was higher than that in other regions in Zhejiang Province (38.4%(33/86)), and the difference was statistically significant ( χ2=6.46, P=0.011). E. coli was sensitive to meropenem (0/45), and 74.4%(32/43) of them were resistant to ampicillin. E. coli had different degrees of resistance to other common cephalosporins, among which, cefotaxime had the highest resistance rate of 41.8%(23/55), followed by ceftriaxone (32.4%(23/71)). S. agalactiae was sensitive to penicillin, vancomycin and linezolid. Conclusions:The composition ratios of pathogenic bacteria of neonatal purulent meningitis are different in different regions of China. The most common pathogen is E. coli, which is sensitive to meropenem, while it has different degrees of resistance to other common cephalosporins, especially to cefotaxime.

Objective     To analyze the efficacy of off-pump coronary artery bypass grafting (OPCABG) in elderly patients with coronary artery disease complicated with moderate ischemic mitral regurgitation. Methods     The clinical data of patients aged≥70 years with coronary artery disease complicated with moderate mitral regurgitation, and undergoing OPCABG from January 2009 to January 2020 in Beijing Anzhen Hospital were retrospectively analyzed. The echocardiographic indicators of the patients were compared preoperatively, postoperatively before discharge and during the follow-up. Results     Finally 239 patients were enrolled. There were 136 males and 103 females, aged 74.1±3.2 years. Before postoperative discharge, 49 (20.5%) patients had no mitral regurgitation, 144 (60.3%) mild regurgitation, 46 (19.2%) moderate regurgitation, and 0 severe regurgitation. The area of mitral regurgitation was significantly improved (2.5±1.8 cm2 vs. 5.6±1.0 cm2, P<0.001). There were 10 (4.2%) patients of hospital death, 23 (9.6%) of low cardiac output, 3 (1.3%) of myocardial infarction, and 8 (3.3%) of nervous system injury after operation. As a result, 208 (90.8%) patients were followed up and the mean follow-up time was 3.4 years (range 1-9 years). The cumulative survival rates at postoperative 2, 4, 6, and 8 years were 95.8%, 88.0%, 78.4%, and 73.1%, respectively. Postoperative follow-up showed significant improvements compared with those before surgery in the area of mitral regurgitation, left ventricular ejection fraction, left ventricular end-diastolic and left ventricular end-systolic diameters (all P<0.05). Duirng the follow-up, the major adverse cardiac and cerebrovascular events were all cause death in 22 (10.6%) patients, including cardiac death in 17 (8.2%) patients, myocardial infarction in 7 (3.4%) patients, heart failure in 24 (11.5%) patients, cerebrovascular events in 11 (5.3%) patients, re-hospitalization due to heart disease in 23 (11.1%) patients, and none of the patients with myocardial infarction were revascularized. Conclusion     The mid- and long-term outcomes of OPCABG in the treatment for elderly patients with coronary artery disease complicated with moderate ischemic mitral regurgitation is good.

Osteofacial compartment syndrome (OCS) is one of the serious complications in traumatic orthopedics. If not treated in time, OCS may result in irreversible damage to nerve and muscle,even amputation or death in serious condition. 5P presents to be the classic clinical diagnosis of OCS, but it is highly subjective and cannot timely and accurately judge the progression of the disease. Intracompartment pressure manometry is the main auxiliary method for the diagnosis of OCS. Although there are many manometry methods, there is still no authoritative pressure threshold as the diagnosis standard. Clinicians often aggressively perform fasciotomy to avoid serious complications, leading to unnecessary fasciotomy. The authors retrospectively reviewed the data of patients with OCS treated at Air Force Hospital of Eastern Theater of PLA from March 2010 to March 2020 and found that some patients with OCS had gradual alleviation of clinical symptoms after appropriate conservative treatments such as brace releasing, limb stabilization and swelling subsidence, with no need of fasciotomy. However, the symptoms of some patients progressively aggravated after the above-mentioned traditional treatments and timely fasciotomy was required. The authors graded the severity of OCS and proposed for the first time the OCS grading criteria according to quantitative clinical results and quantitative indicators such as ratio of mean blood flow velocity of bilateral arteries and pulse wave changes, aiming to take corresponding intervention measures for patients with different OCS classifications, carry out more precise treatment and avoid unnecessary fasciotomy.

Objective:To explore the protective effect and mechanism of improved St. Thomas solution on canine skeletal muscle ischemia-reperfusion injury (IRI).Methods:Between March 2021 and September 2021, in the experimental operating room at the Air Force Hospital of the PLA Eastern Theater Command, 16 Beagles were randomly divided into control group, IRI group, IRI+NS group, and improved St. Thomas group, 4 in each group. The canine skeletal muscle IRI model was established, and the canine vital signs were monitored by pre-perfusion with improved St. Thomas perfusate [potassium chloride (KCl), magnesium sulfate (MgSO 4), and NaHCO 3 (pH adjusted)]. The pathological damage of canine skeletal muscle was explored by hematoxylin eosin (HE) staining, electron microscope detection and tissue wet/dry weight ratio, and blood vessel density. Hypoxia performances were detected by labeling blood vessels and hypoxia-inducible factor-1α (HIF-1α). The IRI model of L6 rat myoblasts was established, and the components of St. Thomas perfusion solution were pre incubated to explore the effect on the inhibition of cell proliferation. And by detecting reduced nicotinamide adenine dinucleotide phosphate (NADPH), F2 isoprostane (F2-isoprostane), interleukin 1β(IL-1β), tumour necrosis factor alpha (TNF-α), myeloperoxide enzyme (MPO), glutathione peroxidase (GSH-Px), etc. to explore its protective mechanism. Statistical software SPSS 23.0 was used for statistical analysis, A P<0.05 was set as statistically significant. Results:In the improved St. Thomas group, the vital signs of the dogs were relatively stable, the amount of maintained dopamine was less, the histopathological structure of the gastrocnemius muscle tended to be intact, the swelling of tissue cells and mitochondria was significantly relieved, and the tissue wet/dry weight ratio was less than that in the IRI group ( P=0.046). Pre-incubated with therapeutic doses of MgSO 4 or NaHCO 3, the proliferation rate of L6 cells was higher than that of IRI group ( P<0.01, P=0.005), NADPH ( P=0.004, P=0.001), F2-isoprostane ( P<0.01, P=0.01), IL-1β ( P=0.02, P=0.015), TNF-α ( P<0.01, P<0.01), MPO ( P<0.01, P<0.01) were all lower than those in the IRI group, except GSH-Px that was higher than what in the IRI group ( P<0.01). Conclusion:Pre-perfusion of the improved St. Thomas solution can stabilise the vital signs of dogs in a short period of time. The solution can improve the state of skeletal muscle cells, improve tissue hypoxia, and reduce the damage of skeletal muscle tissue cells through anti-inflammatory and anti-oxidative stress.
