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.

Pyran- and furanocoumarins are key representatives of tetrahydropyrans and tetrahydrofurans, respectively, exhibiting diverse physiological and medical bioactivities. However, the biosynthetic mechanisms for their core structures remain poorly understood. Here we combined multiomics analyses of biosynthetic enzymes in Peucedanum praeruptorum and in vitro functional verification and identified two types of key enzymes critical for pyran and furan ring biosynthesis in plants. These included three distinct P. praeruptorum prenyltransferases (PpPT1-3) responsible for the prenylation of the simple coumarin skeleton 7 into linear or angular precursors, and two novel CYP450 cyclases (PpDC and PpOC) crucial for the cyclization of the linear/angular precursors into either tetrahydropyran or tetrahydrofuran scaffolds. Biochemical analyses of cyclases indicated that acid/base-assisted epoxide ring opening contributed to the enzyme-catalyzed tetrahydropyran and tetrahydrofuran ring refactoring. The possible acid/base-assisted catalytic mechanisms of the identified cyclases were theoretically investigated and assessed using site-specific mutagenesis. We identified two possible acidic amino acids Glu303 in PpDC and Asp301 in PpOC as vital in the catalytic process. This study provides new enzymatic tools in the epoxide formation/epoxide-opening mediated cascade reaction and exemplifies how plants become chemically diverse in terms of enzyme function and catalytic process.

Objective To understand the prevalence and risk factors of hyperuricemia in electronics factory workers in Wuhan, and to provide evidence for the health protection of electronics factory workers. Methods A total of 1 415 employees in an electronics factory in Wuhan were selected as the research subjects, and the physical examination and determination of various biochemical indicators, as well as questionnaire survey were carried out. Results The detection rate of hyperuricemia among workers in the electronics factory in Wuhan was 32.43%, with 36.33% for men and 14.11% for women, and the difference was statistically significant ( χ²＝46.077，P＜0.001). The detection rate of hyperuricemia was the highest (33.77%) among those with university or college education, followed by graduate students and above (31.50%). Compared with subjects with good lifestyle habits, people with drinking habits had higher hyperuricemia detection rate (49.38%), and the difference was statistically significant (P =0.001). The detection rates of hyperuricemia in those with central obesity and elevated alanine aminotransferase were 48.23% and 61.29%, respectively, which were significantly higher than those in the subjects without the above diseases (26.91% and 27.21%, respectively), and the differences were statistically significant (P <0.001). Obese people had the highest detection rate of hyperuricemia (66.95%), followed by overweight people (43.75%), and the difference was statistically significant (P <0.001). Multivariate logistic analysis showed that alcohol drinking (OR=1.836, 95% CI=1.139-2.961, P =0.013) and body mass index ≥ 24 kg/m² (OR=2.175, 95% CI=1.686 -2.806, P <0.001) were risk factors for hyperuricemia in electronic factory workers. Elevated alanine aminotransferase (ALT) was significantly correlated with hyperuricemia (OR=2.964, 95%CI=2.146-4.095 , P <0.001). Female gender was a protective factor for hyperuricemia in workers in the electronics factory (OR=0.441, 95%CI=0.297-0.653 , P <0.001). Conclusion The detection rate of hyperuricemia among workers in an electronics factory in Wuhan is high, and the detection rate of hyperuricemia in men is higher than that in women. Alcohol consumption, overweight and obesity will increase the risk of hyperuricemia. Elevated ALT is associated with hyperuricemia. Maintaining an ideal body mass index and establishing a good lifestyle play an important role in preventing hyperuricemia.

Ankylosing spondylitis (AS) combined with lower cervical fracture is often categorized into unstable fracture, with a high incidence of neurological injury and a high rate of disability and morbidity. As factors such as shoulder occlusion may affect the accuracy of X-ray imaging diagnosis, it is often easily misdiagnosed at the primary diagnosis. Non-operative treatment has complications such as bone nonunion and the possibility of secondary neurological damage, while the timing, access and choice of surgical treatment are still controversial. Currently, there are no clinical practice guidelines for the treatment of AS combined with lower cervical fracture with or without dislocation. To this end, the Spinal Trauma Group of Orthopedics Branch of Chinese Medical Doctor Association organized experts to formulate Clinical guidelines for the treatment of ankylosing spondylitis combined with lower cervical fracture in adults ( version 2024) in accordance with the principles of evidence-based medicine, scientificity and practicality, in which 11 recommendations were put forward in terms of the diagnosis, imaging evaluation, typing and treatment, etc, to provide guidance for the diagnosis and treatment of AS combined with lower cervical fracture.

Inflammasome is a kind of intracellular polyprotein complex,which is an important component of the complex system of local inflammatory microenvironment after human tissue damage.When the inflammasome is activated,it induces the activation of cysteine aspartate proteinase 1(caspase-1),mediates the maturation and secretion of proinflammatory cytokines,such as interleukin(IL)-1 β and IL-18,and induces cell death,which plays an important role in regulating the host immune response to pathogen infection and tissue repair of cell damage.Nod-like receptor protein 3(NLRP3)inflammatory body,which is composed of NLRP3,pro-cysteine aspartic acid specific protease-1(pro-caspase-1)and apoptosis-related spot-like protein(ASC),is the most deeply and widely studied type of inflammatory body,which plays an important role in the regulation of inflammation.When NLRP3 inflammatory bodies are activated,inflammatory mediators are produced and released,which participate in the occurrence and development of a variety of inflammatory diseases.Some studies have shown that traditional Chinese medicine can improve the pathological state of a variety of diseases by inhibiting NLRP3 inflammatory bodies,and play a role in the prevention and treatment of a variety of inflammatory diseases,including cardiovascular diseases,joint inflammation,diabetes and so on.This paper systematically combs the mechanism of NLRP3 inflammatory bodies,and summarizes the latest research reports on the effects of traditional Chinese medicine compound prescription,traditional Chinese medicine monomers and traditional Chinese medicine extracts on NLRP3 inflammatory bodies in the treatment of inflammatory diseases,in order to provide new ideas for the further study of the pathogenesis and drug treatment of many inflammatory diseases.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective To establish a more scientific and reasonable evaluation method for the heat resistance,freezing resistance,and thermal stability of glass containers for pharmaceutical packaging to meet the regulatory needs of drugs in the new situation.Methods A survey was conducted on domestic injection production enterprises in the form of a questionnaire,including the process parameters of cleaning for glass containers for pharmaceutical packaging,terminal sterilization during injection production,and the freeze-drying process flow of freeze-dried formulations.Results The parameters of dry heat sterilization,freeze-drying,and moist heat sterilization used in actual production of injections vary widely,and evaluation through laboratory simulation under single conditions lacks scientific and practical applicability.Conclusions In order to implement the construction of the new standard system for glass packaging materials in 2025 edition of the Chinese Pharmacopoeia,through this investigation,the actual production process parameters of drugs were shown,and it is proposed that specific experimental conditions for heat resistance,freezing resistance,and thermal stability will no longer be limited in the new standard system for use.Suitable experimental conditions can be set by enterprises based on their actual process to evaluate performance.

Objective:To investigate the long-term therapeutic effects and safety of renal denervation (RDN) on hypertensive patients with different cardiovascular risks, as well as its impact on adverse events, cardiovascular death and all-cause mortality.Methods:This was a single-center, single-arm, real-world retrospective study. Patients with refractory hypertension who underwent RDN at Tianjin First Central Hospital from July 6, 2011 to December 23, 2015 were enrolled and divided into either a high or intermediate-low risk group based on baseline cardiovascular risk. The treatment responsiveness of hypertensive patients with different cardiovascular stratification to RDN was assessed by comparing the results of office blood pressure, home blood pressure, and 24-h ambulatory blood pressure monitoring at 1, 5, and 11 years after RDN. Long-term safety of RDN was assessed by creatinine, and estimated glomerular filtration rate (eGFR) at 1 and 11 years after RDN. In addition, the total defined daily dose (DDD) of antihypertensive medications and the incidence of long-term adverse events, cardiovascular deaths, and all-cause deaths after RDN were followed up 11 years after RDN in person or by telephone.Results:A total of 62 patients with refractory hypertension, aged (50.2±15.0) years, of whom 35 (56.5%) were male, were included. There were 35 cases in high-risk group and 27 cases in low and medium risk group. The decrease in clinic systolic blood pressure (high risk vs. low-medium risk: (-38.0±15.1) mmHg vs. (-25.0±16.6) mmHg(1 mmHg=0.133kPa), P=0.002), home self-measured systolic blood pressure ((-28.4±12.7) mmHg vs. (-19.7±13.1) mmHg, P=0.011) and clinic systolic blood pressure 11 years after RDN ((-43.0±18.4) mmHg vs. (-27.8±17.9) mmHg, P=0.003) in the high-risk group was significantly higher than that in the low-medium risk group. The differences in heart rate and the decrease in total DDD number of antihypertensive drugs between the two groups were not statistically significant (all P>0.05). Creatinine and eGFR levels in the two groups at 1 and 11 years after RDN were not statistically significant when compared with the baseline values (all P>0.05). The cumulative cardiovascular mortality rate was 1.6% (1/62) and 8.1% (5/62), and the cumulative all-cause mortality rate was 3.2% (2/62) and 11.3% (7/62) at 5 and 11 years after RDN, respectively. The differences in the incidence rate of adverse events, cardiovascular mortality, and all-cause mortality rate between the two groups were not statistically significant (all P>0.05). Conclusions:RDN has long-term antihypertensive effect and good safety. Hypertensive patients who belong to the high-risk stratification of cardiovascular risk may respond better to RDN treatment.

Objective:To investigate the correlation between computed tomography (CT) findings and serum micrornA-497 (miR-497), carbohydrate polypeptide antigen 24-2 (CA24-2) and hepatitis B surface antigen (HBsAg) expression in patients with colorectal cancer (CRC).Methods:A total of 64 CRC patients admitted to the Jiangsu Cancer Hospital from January 2021 to December 2022 were prospectively selected, and the surgical pathological results were used as the gold standard. Preoperative CT examination and serum miR-497, CA24-2 and HBsAg levels were performed in all patients. The CT images of the patients were analyzed. Pearson correlation analysis was used to evaluate the correlation between CT findings and serum miR-497, CA24-2 and HBsAg expression levels in CRC patients.Results:The CT imaging features of CRC patients were as follows: The intestinal wall was semi-annular in 37.50%(24/64), annular in 32.81%(21/64), localized thickening in 29.69%(19/64), the intestinal lumen was irregular and narrow, and most of the periintestinal fat was blurred in 59.38%(38/64). 67.19%(43/64) showed uneven enhancement, 51.56%(33/64) had lymph node metastasis and 43.75%(28/64) had liver metastasis. Lymph node metastasis in CRC patients was correlated with serum miR-497 and CA24-2 levels (all P<0.05), but not with serum HBsAg levels ( P>0.05). Liver metastasis in CRC patients was associated with serum HBsAg expression ( P<0.05), but not with serum miR-497 and CA24-2 levels (all P>0.05). Other CT findings of CRC patients were not correlated with serum miR-497, CA24-2 and HBsAg levels (all P>0.05). Pearson correlation analysis showed that lymph node metastasis in CRC patients was negatively correlated with the expression level of serum miR-497 ( r=-0.491, P<0.05), while positively correlated with the expression level of serum CA24-2 ( r=0.506, P<0.05). There was no correlation with serum HBsAg expression level ( P>0.05). The occurrence of liver metastasis in CRC patients was negatively correlated with the expression level of serum HBsAg ( r=-0.529, P<0.05), but was not correlated with the expression levels of serum miR-497 and CA24-2 (all P>0.05). Conclusions:CT imaging findings can evaluate the biological behavior of tumor cells in CRC patients to a certain extent, and have a certain correlation with the expression levels of serum miR-497, CA24-2 and HBsAg, which can reflect the lymph node and liver metastasis of tumors, and provide a basis for clinical comprehensive treatment and prognosis prediction of patients.
