Obesity, as a chronic recurrent disease, has become a major public health challenge in China. To implement the requirements of the Healthy China Initiative (2019—2030), under domestic guidelines or consensus statements on overweight and obesity, and in alignment with the latest scientific advances globally, the Quality control protocol for adult overweight and obesity screening in health management (examination) institutions (2025 edition) was developed. This protocol was drafted by the Health Management Center of Shanghai Changzheng Hospital and formulated through multiple rounds of deliberation by experts in China’s health examination quality control field. The protocol establishes unified standards for screening facilities, personnel qualifications, and measurement or testing procedures. It defines specific screening items, outlines a standardized screening pathway, and sets requirements for the final medical review, ensuring the scientific validity, effectiveness, and safety of the screening process. The implementation of this protocol will enhance the consistency of weight management practices for adults across health examination institutions and strengthen the quality control of overweight and obesity screening programs.

The consensus has been reached on the benefits of surgical drainage. However, catheter-related blockage and retrograde infection remain bottleneck problems in the treatment process. To this end, with Huashan Hospital, Fudan University, as the main inventors, a drainage tube dredging umbrella and anti-retrograde infection kit have been designed and applied for the national utility model patent (patent number: ZL 2023 2 1300036.2). The main body of the kit consists of a catheter dredging umbrella, drainage tube, and drainage bag. Several isolation layers are installed in the drainage bag to form a maze structure and a reflux valve is added, thereby increasing the distance and resistance of liquid reflux, greatly reducing the possibility of liquid reflux entering the drainage tube, so as to reduce the risk of retrograde infection through physical means. When the drainage tube is blocked, the drainage tube and joint tube of the drainage bag can be separated, the unblocking umbrella can be inserted into the blockage through the guide wire, the cannula can be inserted along the guide wire, the guide wire is pulled to release the dredging umbrella in the contraction state, and the dredging umbrella can be pulled back in the expansion state until the blockage is removed from the drainage tube. The operating procedure is standardized and simple. While preventing retrograde infection (anti-retrograde infection kit), the catheter dredging umbrella could effectively address the issue of catheter blockage. It has certain clinical promotion and application value.

Ginger mainly contains two main categories of volatile and non-volatile components,of which the non-volatile gingerol is a general term for pungent substances in ginger,mainly containing gingerols,shogaols and other components,with a wide range of pharmacological effects.By reviewing the 2020 edition of the Pharmacopoeia of the People's Republic of China and related literature in Chinese databases such as CNKI and Wanfang,it was found that the use of the Chinese names of gingerols and shogaols was confusing,which caused certain troubles to readers and obstacles to academic exchanges.According to the naming principles of Chinese medicinal extracts,it is suggested that gingersols,6-gingerol,8-gingerol and 10-gingerol should be uniformly named as gingerols(姜酚类),6-gingerol(6-姜酚),8-gingerol(8-姜酚)and 10-gingerol(10-姜酚),respectively,and shogaols and 6-shogaol should be uniformly named as shogaols(姜烯酚类)and 6-shogaols(6-姜烯酚).The standardized use of the Chinese names of gingerols and shogaols will facilitate in-depth research and academic exchange on ginger,dried ginger,baked ginger and other ginger herbal medicines.

Objective To explore the effect of protective ventilation strategies based on individualized positive end expiratory pressure(PEEP)regulated by driving pressure(Pd)in infants under OLV.Methods Sixty infants undergoing elective thoracoscopic surgery were randomly divided into the control group and driving pressure group,with 30 cases in each group.The two groups were compared in terms of MAP,HR,tidal volume(Vt),PEEP,Pd,airway peak pressure(Ppeak),and static lung compliance(Cs),and arterial blood gas during OLV before the artificial pneumothorax(T0),10 min(T1),30 min(T2),and 60 min(T3)after the artificial pneumothorax,and right at the end of the artificial pneumothorax(T4).Results There were no significant differences in MAP,HR,and Vt between the two groups at all the time points(P＞0.05).Both groups showed the increase in Pd and Ppeak and decresase in Cs at T1,T2,and T3(all P＜0.05).PaO2 and OI in both group were decreased and PaCO2 was increased at T2(all P＜0.05).Compared with the control group,the driving pressure group presented lower Pd and Ppeak,higher PEEP and Cs at T1,T2,and T3(P＜0.05),and higher PaO2 and OI(P＜0.05)and no significant differences in PaCO2 and FiO2 at T2(P＜0.05).The rate of rescue ventilation during OLV was lower in the driving pressure group(2 cases)than in the control group(9 cases)(6.9%versus 32.4%,P＜0.05).There was no significant difference in the inci-dence of postoperative complications between the two groups(P＜0.05).Conclusion The individualized positive end expiratory pressure(PEEP)regulated by Pd can optimize the PEEP settings upon infant individuals under OLV and improve the compliance and oxygenation of ventilated lung.

Objective To study the population genetic structure and phylogenetic relationships by combining Y-STR haplotype genetic information from the Han population in Dalian with 32 domestic and foreign groups.Methods Blood samples of 958 Han male volunteers from Dalian were collected.Genetic typing of 42 genetic loci was completed using Y-STR fluorescent reagent kits and capillary electrophoresis.Related forensic parameters were calculated.Nei's standard genetic distances among 33 populations based on 17 Y-STR loci were computed,in order to create a principal coordinate analysis as well as construct a phylogenetic tree.Results The analysis of genetic polymorphisms at 42 Y-STR loci revealed 30 unconventional alleles at 10 loci.Genetic analysis of the population based on 17 Y-STR loci confirmed that Dalian's Han population had the closest genetic distance to the Anshan's Han population,followed by populations from Henan,Heilongjiang,Jilin,Shandong,and Chongqing.Furthermore,the genetic distances between the Han population in Dalian and the Qiang population in Beichuan or the Miao population in Guizhou were relatively closer than that to the Manchu population living in Liaoning.Conclusion The genetic distance between the Han population in Dalian and other groups is not entirely proportional to ethnicities and geographical proximity.Both population migration and ethnic assimilation or isolation may have influence on it.

Objective:To investigate the impact of residual cholesterol (RC) on the progression of arteriosclerosis in individuals receiving physical examination.Methods:A cross-sectional study. Participants aged 18 years and above who underwent arteriosclerosis testing at the Health Management Center of Zigong Fourth People′s Hospital from January to December 2023 were selected as the subjects of the study. A total of 9 016 subjects were included in this study, of whom 6 213 were considered to have arteriosclerosis. The physical examination conclusions, basic information (age, gender, body mass index, waist circumference, blood pressure, history of hypertension, history of smoking and drinking), and biochemical indicators (lipids, fasting blood glucose, liver and kidney function) were extracted in those individuals. Based on the examination results, the subjects were categorized into arteriosclerosis and normal groups. The RC levels of the participants were calculated using a formula and then the subjects were categorized into binary and quartile RC groups. Additionally, four regression models were used to analyze the impact of RC levels on the progression of arteriosclerosis while adjusting for various confounding factors.Results:The RC level was (0.63±0.44) mmol/L in the normal group and (0.76±0.61) mmol/L in the arteriosclerosis group. Based on level of RC, the normal group was divided into two subgroups: 652 individuals with elevated RC level and 2 241 with normal RC level. In the arteriosclerosis group, there were 2 069 individuals with elevated RC level and 4 144 with normal RC level. Grouped according to quartiles of RC level, the number of individuals with RC in the Q1-Q4 interval in the normal group was 838 (28.97%), 752 (25.99%), 760 (26.27%), and 543 (18.77%), respectively, showing a gradual decreasing trend. The number of individuals with RC in the Q1-Q4 interval in the arteriosclerosis group was 1 414 (22.76%), 1 438 (23.15%), 1 589 (25.58%), and 1 771 (28.51%), respectively, showing a gradual increasing trend. The difference between the groups was statistically significant ( P<0.05). After adjusting for various factors by four regression models, it was found that elevated RC levels increased the risk of arteriosclerosis progression, with a odds ratio ( OR) of 1.381, 1.242, 1.233, and 1.214, respectively. Additionally, individuals in the Q4 RC level quartile had 1.502, 1.318, 1.311, and 1.284-times higher risk of arteriosclerosis progression when compared to those in the Q1 quartile. Conclusion:The impact of RC on the progression of arteriosclerosis tend to stabilize and remain consistent, indicating that elevated RC is an independent risk factor for the progression of arteriosclerosis.

Dexmedetomidine displays multiple mechanisms of neuroprotection in ameliorating ischemic brain injury. In this study, we explored the beneficial effects of dexmedetomidine on blood-brain barrier (BBB) integrity and neuroinflammation in cerebral ischemia/reperfusion injury. Sprague-Dawley rats were subjected to middle cerebral artery occlusion (MCAO) for 1.5 h and reperfusion for 24 h to establish a rat model of cerebral ischemia/reperfusion injury. Dexmedetomidine (9 µg/kg) was administered to rats 30 min after MCAO through intravenous injection, and SB203580 (a p38 MAPK inhibitor, 200 µg/kg) was injected intraperitoneally 30 min before MCAO. Brain damages were evaluated by 2,3,5-triphenyltetrazolium chloride staining, hematoxylin-eosin staining, Nissl staining, and brain water content assessment. BBB permeability was examined by Evans blue staining. Expression levels of claudin-5, zonula occludens-1, occludin, and matrix metalloproteinase-9 (MMP-9) as well as M1/M2 phenotypes-associated markers were assessed using immunofluorescence, RT-qPCR, Western blotting, and gelatin zymography. Enzyme-linked immunosorbent assay was used to examine inflammatory cytokine levels. We found that dexmedetomidine or SB203580 attenuated infarct volume, brain edema, BBB permeability, and neuroinflammation, and promoted M2 microglial polarization after cerebral ischemia/reperfusion injury. Increased MMP-9 activity by ischemia/reperfusion injury was inhibited by dexmedetomidine or SB203580. Dexmedetomidine inhibited the activation of the ERK, JNK, and p38 MAPK pathways. Moreover, activation of JNK or p38 MAPK reversed the protective effects of dexmedetomidine against ischemic brain injury. Overall, dexmedetomidine ameliorated brain injury by alleviating BBB permeability and promoting M2 polarization in experimental cerebral ischemia/reperfusion injury model by inhibiting the activation of JNK and p38 MAPK pathways.

Radiotherapy is widely used in the management of advanced colorectal cancer (CRC). However, the clinical efficacy is limited by the safe irradiated dose. Sensitizing tumor cells to radiotherapy via interrupting DNA repair is a promising approach to conquering the limitation. The BRCA1-BARD1 complex has been demonstrated to play a critical role in homologous recombination (HR) DSB repair, and its functions may be affected by HERC2 or BAP1. Accumulated evidence illustrates that the ubiquitination-deubiquitination balance is involved in these processes; however, the precise mechanism for the cross-talk among these proteins in HR repair following radiation hasn't been defined. Through activity-based profiling, we identified PT33 as an active entity for HR repair suppression. Subsequently, we revealed that BAP1 serves as a novel molecular target of PT33 via a CRISPR-based deubiquitinase screen. Mechanistically, pharmacological covalent inhibition of BAP1 with PT33 recruits HERC2 to compete with BARD1 for BRCA1 interaction, interrupting HR repair. Consequently, PT33 treatment can substantially enhance the sensitivity of CRC cells to radiotherapy in vitro and in vivo. Overall, these findings provide a mechanistic basis for PT33-induced HR suppression and may guide an effective strategy to improve therapeutic gain.

Objective:To investigate the changes in dynamic functional connectivity density (dFCD) and its relationship with Fagerstr?m test for nicotine dependence (FTND) scores in individuals with smoking addiction based on functional MR.Methods:The clinical and imaging data of 176 volunteers recruited through wechat and other online platforms from September 2019 to December 2020 in the First Affiliated Hospital of Zhengzhou University were retrospectively analyzed. The 176 volunteers were male, aged 20 to 55 years old, and were divided into light smoking addiction group (59 cases), heavy smoking addiction group (61 cases) and control group (56 cases). All subjects underwent resting state functional MR scanning and dFCD was calculated. The dFCD values of three groups were analyzed by ANOVA analysis (GRF corrected, voxel level P<0.005, cluster level P<0.01). Bonferroni correction was used for pairwise comparison. Pearson partial correlation analysis was used to analyze the correlation between dFCD values of brain regions with statistically significant differences and FTND scores. Results:Differences in dFCD among light smoking addiction group, heavy smoking addiction group and control group were mainly distributed in the right orbitofrontal cortex, left caudate nucleus, right putamen, bilateral calcarine sulcus cortex, right cuneus, left parahippocampal gyrus, left precuneus, left middle temporal gyrus and bilateral thalamus (GRF corrected, voxel level P<0.005, cluster level P<0.01). Compared with the control group, both the light and heavy smoking addiction groups showed decreased dFCD in the bilateral calcarine sulcus cortex, right cuneus and left precuneus, as well as increased dFCD in the right orbitofrontal cortex, right putamen, left caudate nucleus and left thalamus (Bonferroni corrected, P<0.05). Compared with the control group, the heavy smoking addiction group showed increased dFCD in the right thalamus, and the light smoking addiction group showed decreased dFCD in the left middle temporal gyrus (Bonferroni corrected, P<0.001). Compared with the light smoking addiction group, the heavy smoking addiction group showed increased dFCD in the left middle temporal gyrus and right thalamus, and decreased dFCD in the left parahippocampal gyrus (Bonferroni corrected, P<0.05). The mean value of dFCD in the right thalamus was positively correlated with FTND scores in smoking addiction patients ( r=0.227, P=0.014), and the mean value of dFCD in the right thalamus of the heavy smoking addiction subgroup was positively correlated with FTND scores ( r=0.323, P=0.013). There was no correlation between FTND scores and dFCD in the right thalamus of the light smoking addiction group ( P>0.05). Conclusion:There are changes of neural activity in brain regions related to smoking behaviors among people with different severity of smoking addiction, and smoking behaviors of people with heavy smoking addiction tend to be habitual compared with those with light smoking addiction.
