ObjectiveTo investigate the effects of Huangqi Jianzhongtang （HQJZ） on macrophage polarization and fat consumption in cancer cachexia （CC） mice. MethodsUltra-performance liquid chromatography-quadrupole/electrostatic field Orbitrap high-resolution mass spectrometry （UPLC-Q-Orbitrap HRMS） was used to control the quality of HQJZ. （1） In vitro experiment： HQJZ-containing serum was prepared， and the optimal concentration was determined by cytotoxicity assay. Mouse monocyte-derived macrophages （RAW264.7） were cultured and randomly divided into six groups， including a blank group， a classically activated macrophages （M1） group， an alternatively activated macrophages （M2） group， a HQJZ + blank group， a HQJZ+M1 group， and a HQJZ + M2 group. The relative expression of macrophage marker genes CD86， inducible nitric oxide synthase （iNOS）， CD206， and arginase-1 （Arg1） was detected by real-time quantitative polymerase chain reaction （Real-time PCR ）. （2） In vivo experiment： Thirty-two BALB/c mice were randomly divided into a control group， a model group， a medroxyprogesterone acetate （MPA） group， and a HQJZ group. Except for the control group， the other mice were injected with CT-26 colon cancer cells to establish a CC model. Mice in the MPA and HQJZ groups were given MPA （0.13 g·kg^-1·d^-1） or HQJZ （13.13 g·kg^-1·d^-1） by gavage， respectively， while mice in the control and model groups were given an equal volume of saline by gavage， with interventions continued for 10 d. Real-time PCR was used to detect the expression of macrophage markers （iNOS， Arg1， CD86， CD206） and fat browning-related genes uncoupling protein 1 （UCP1） and peroxisome proliferator-activated receptor γ （PPARγ） in epididymal adipose tissue. Western blot （WB） was used to detect protein expression levels of UCP1 and PPARγ. Micro-computed tomography （micro-CT） was used to measure residual fat volume， and hematoxylin-eosin （HE） staining was used to assess fat browning and calculate pathological scores. ResultsIn vitro， the dominant effective concentration of HQJZ-containing serum was 12.5%. Real-time PCR results showed that， compared with the blank group， Arg1 expression decreased in the HQJZ+blank group （P<0.05）， CD206 showed a downward trend without statistical significance， while iNOS and CD86 expression were significantly increased （P<0.05）. Compared with the M1 group， Arg1 and CD206 expression decreased in the HQJZ+M1 group （P<0.05）. Compared with the M2 group， CD206 expression decreased in the HQJZ+M2 group （P<0.05）， CD86 expression increased significantly （P<0.01）. In vivo， Real-time PCR results showed that， compared with the control group， CD86 and CD206 expression levels were significantly increased in the model group （P<0.01）. Compared with the model group， CD206 expression in the MPA group was significantly decreased （P<0.01）. In the HQJZ group， CD206 was significantly decreased （P<0.01）. WB results showed that， compared with the model group， protein expression of UCP1 and PPARγ was significantly reduced in the HQJZ group （P<0.05， P<0.01）. micro-CT results showed that the total white fat volume in the HQJZ group was greater than that in the model group （P<0.05）. HE staining results showed that pathological scores in the HQJZ group were lower than those in the model group （P<0.05）. ConclusionHQJZ may inhibit white adipose tissue browning by promoting macrophage M1 polarization and suppressing M2 polarization， thereby delaying fat consumption in CC mice.

ObjectiveTo investigate the incidence of postherpetic neuralgia （PHN） and its associated risk factors in patients aged ≥50 years with herpes zoster （HZ） who received standard antiviral therapy at the dermatology outpatient clinic of our center. MethodsHZ patients were identified by searching the medical record system using "herpes zoster" as the keyword， and those diagnosed between July 2020 and July 2021. Patients meeting the inclusion criteria were followed up via telephone to retrospectively assess the occurrence of PHN. Patients were divided into a PHN group and a non-PHN group based on the presence of PHN. General patient information （gender， age， and underlying diseases）， prodromal pain intensity， and lesion characteristics （area， location， and acute-phase pain intensity） as well as treatment modalities （pharmacotherapy， physical therapy， and combined analgesic therapy） were compared between the two groups. Intergroup comparisons and multifactorial analyses were performed to identify factors associated with the development of PHN in HZ patients. Pain intensity was assessed using the Numerical Rating Scale （NRS） for PHN pain， acute-phase HZ pain， and prodromal pain. Intergroup comparisons were conducted using the chi-square test， Mann-Whitney U test， and t-test. Binary logistic regression was used for multivariate analysis to identify independent risk factors. ResultsA total of 238 HZ patients aged ≥50 years who received standard antiviral therapy were ultimately included， of whom 76 （31.9%） developed PHN. Unifactorial analysis showed that age， lesion area， acute-phase pain intensity， and the use of gabapentin or combined analgesic therapy significantly influenced the occurrence of PHN after HZ （P<0.05）. Statistically significant indicators （P<0.05） from the unifactorial analysis and the different analgesic regimens adopted by patients were included in the multifactorial analysis. Multifactorial analysis revealed that lesion area ≥1% （OR=2.501； 95%CI=1.408-4.443； P=0.002<0.05） and acute-phase pain score （OR=1.160； 95%CI=1.028-1.309； P=0.016<0.05） were independent risk factors for PHN. Age and the use of gabapentin or combined analgesic therapy showed no statistically significant association with the occurrence of PHN （P>0.05）. ConclusionsIn HZ patients aged ≥50 years receiving standard antiviral therapy， the incidence of PHN is 31.9%. A lesion area ≥1% and higher acute-phase pain NRS scores are identified as independent risk factors for the development of PHN in these patients.

Community general practitioners are the main force of primary health care, however, the lack of effective incentive mechanisms would affect their work enthusiasm. Therefore, to enhance incentive mechanisms,particularly from the perspective of the career development,will improve the work enthusiasm and post competeny of general practitioners in primary health care services. This article summarizes five major influencing factors of the incentives for community general practitioners, namely salary and benefits, performance evaluation, promotion and development, working conditions and interpersonal relationships, and proposes the operational strategies of incentive improvement, to provide reference for improving working conditions and strengthening incentive measures for community general practioners in primary community hospitals.

Objective:To systematically identify and summarize the best available evidence on feeding management during the peridischarge period for very low birth weight infants (VLBWI) and extremely low birth weight infants (ELBWI), providing a reference for clinical nursing practice.Methods:Evidence on feeding management for VLBWI/ELBWI during the peridischarge period was retrieved from decision support systems, guideline repositories, major databases, and relevant professional organizations' websites. Sources included clinical decisions, guidelines, evidence summaries, systematic reviews, expert consensus documents and so on. The search spanned from database inception to April 2024. Guidelines were reviewed by four researchers, while other documents were screened and appraised by two researchers.Results:A total of 24 documents were included: six clinical decision tools, four guidelines, three systematic reviews, three evidence summaries, and eight expert consensus statements. A total of three primary themes, 10 secondary themes, and 49 best evidence items were synthesized. These covered: pre-discharge feeding management (establishing a peridischarge feeding team, parental feeding education, assessing feeding status of VLBWI/ELBWI, evaluating parental feeding competence, preparing feeding materials/environment and assessing community resources) ; discharge feeding management (providing feeding-related medical records and developing individualized feeding plans) ; post-discharge feeding management (setting growth and development goals, conducting follow-up and growth monitoring, and supplementing necessary nutrients) .Conclusions:The summarized best evidence provides a practical reference for healthcare professionals to effectively implement feeding management for VLBWI/ELBWI during the peridischarge period. Evidence-based strategies should be selectively applied in clinical practice based on individual conditions to ensure a successful transition to home feeding and support healthy growth and development of VLBWI/ELBWI.

Objective : To investigate the effect of chromosome instability(CIN) associated gene polypeptide N-acetylgalactosaminyltransferase 7(GALNT7) on proliferation and apoptosis of HCT116 colon cancer cells. Methods : The HCT116 cell line withGALNT7knockdown was constructed by lentiviral infection. The correlation betweenGALNT7and CIN was verified by chromosome spread assay. The effect ofGALNT7on cell proliferation was detected by live cell counting, and the effect ofGALNT7on cell cycle distribution was detected by flow cytometry and Western blot. Caspase-3 activity and Western blot assays were used to detect the effect ofGALNT7on apoptosis. Results : HCT116 cells showed a slower proliferation rate upon knocking down ofGALNT7, and exhibited a more scattered karyotype distribution and a phenotype of increased degree of CIN. Inhibition ofGALNT7in HCT116 cells resulted in cell cycle arrest, upregulation of P21 and downregulation of CDK6 protein levels, as well as increased levels of Caspase-3 activity, cleaved PARP1 and PUMA protein expression, and decreased levels of BCL-2 protein expression. Conclusion TheGALNT7gene may promote proliferation and inhibit apoptosis of HCT116 colon cancer cells through the suppression of CIN generation.

The focus of green analytical chemistry(GAC)is to minimize the negative impacts of analytical pro-cedures on human safety,human health,and the environment.Several factors,such as the reagents used,sample collection,sample processing,instruments,energy consumed,and the quantities of hazardous materials and waste generated during analytical procedures,need to be considered in the evaluation of the greenness of analytical assays.In this study,we propose a greenness evaluation metric for analytical methods(GEMAM).The new greenness metric is simple,flexible,and comprehensive.The evaluation criteria are based on both the 12 principles of GAC(SIGNIFICANCE)and the 10 factors of sample prep-aration,and the results are presented on a 0-10 scale.The GEMAM calculation process is easy to perform,and its results are easy to interpret.The output of GEMAM is a pictogram that can provide both qualitative and quantitative information based on color and number.

Combined with elastic network model(ENM),the perturbation response scanning(PRS)has emerged as a robust technique for pinpointing allosteric interactions within proteins.Here,we proposed the PRS analysis of drug-target networks(DTNs),which could provide a promising avenue in network medicine.We demonstrated the utility of the method by introducing a deep learning and network perturbation-based framework,for drug repurposing of multiple sclerosis(MS).First,the MS comorbidity network was constructed by performing a random walk with restart algorithm based on shared genes between MS and other diseases as seed nodes.Then,based on topological analysis and functional annotation,the neurotransmission module was identified as the"therapeutic module"of MS.Further,perturbation scores of drugs on the module were calculated by constructing the DTN and introducing the PRS analysis,giving a list of repurposable drugs for MS.Mechanism of action analysis both at pathway and structural levels screened dihydroergocristine as a candidate drug of MS by targeting a serotonin receptor of se-rotonin 2B receptor(HTR2B).Finally,we established a cuprizone-induced chronic mouse model to evaluate the alteration of HTR2B in mouse brain regions and observed that HTR2B was significantly reduced in the cuprizone-induced mouse cortex.These findings proved that the network perturbation modeling is a promising avenue for drug repurposing of MS.As a useful systematic method,our approach can also be used to discover the new molecular mechanism and provide effective candidate drugs for other complex diseases.
