OBJECTIVE To study the improvement effect and mechanism of sanguinarine （SG） on inflammatory pain in rats with lumbar disc herniation （LDH） and its mechanism. METHODS LDH model rats were established and divided into model group， SG low-dose， medium-dose and high-dose groups （1.00， 2.50， 6.25 mg/kg）， high-dose of SG+Anisomycin [mitogen-activated protein kinase （MAPK） activator] group （6.25 mg/kg SG+5 mg/kg Anisomycin）， with 10 rats in each group. Another 10 rats were included as the control group. Each group was given corresponding drugs intraperitoneally， while the control group and model group were given an equal volume of normal saline intraperitoneally， once a day， for 7 consecutive days. The general situation and neurological changes of rats in each group were observed， and the pain threshold [including paw withdrawal mechanical threshold （PWMT） and paw withdrawal thermal latency （PWTL）] of rats was determined； the histopathological changes of dorsal root ganglion （DRG） were observed in rats. The serum levels of inflammatory factors [tumor necrosis factor-α （TNF-α）， interleukin-1β （IL-1β）] and pain factors [neuropeptide Y （NPY）， 5-hydroxytryptamine （5-HT）] in rats were detected.The positive expressions of ionized-calcium binding adaptor molecule-1 （Iba-1） in spinal cord microglia and glial fibrillary acidic protein （GFAP） in astrocytes were observed. The expressions of proteins related to MAPK/extracellular signal-regulated kinase （ERK）/nuclear factor κB （NF-κB） signaling pathway， TNF-α and IL-1β proteins were detected in DRG tissue of rats. RESULTS Compared with the control group， the rats in the model group showed decreased appetite， hindlimb movement disorders， and disordered neuronal cell arrangement， the neurological score， the levels of TNF-α， IL-1β， NPY， the positive expressions of Iba-1 and GFAP， the phosphorylations of p38 MAPK， ERK1/2 and NF-κB p65， the protein expressions of TNF-α and IL-1β were significantly increased （P＜0.05）； PWMT， PWTL and the levels of 5-HT were significantly reduced （P＜0.05）. Compared with the model group， the rats of SG groups showed some relief in their mental appetite and hindlimb motor disorders， the intervertebral disc structure of DRG was restored， and the levels of the above quantitative indicators had significantly reversed （P＜0.05）. Anisomycin reversed the improvement effect of SG on inflammatory pain in LDH rats. CONCLUSIONS SG can improve inflammatory pain by inhibiting the activation of microglia in DRG tissue of LDH rats， reducing the release of inflammatory factors， and increasing pain threshold， and its mechanism of action may be related to the inhibition of MAPK/ERK/NF- κB signaling pathway.

In recent years， the incidence of pulmonary nodules has kept rising. To give full play to the advantages of traditional Chinese medicine （TCM） in the treatment of pulmonary nodules and identify the breakthrough points of integrating TCM with Western medicine， the China Association of Chinese Medicine organized medical experts in TCM and western medicine to carry out in-depth discussion regarding this disease. The discussion encompassed the modern medical advances， TCM theories of etiology and pathogenesis， the role and advantages of TCM in the whole course management of pulmonary nodules， contents and methods of research on pulmonary nodules， and science popularization work， aiming to provide a reference for clinical practice and scientific research. After discussion， the experts concluded that the occurrence of pulmonary nodules was rooted in the deficiency of the lung and spleen and triggered by phlegm dampness， blood stasis， and Qi stagnation. TCM can treat pulmonary nodules by controlling and reducing nodules， improving physical constitution， ameliorating multi-system nodular diseases， reducing anxiety and avoiding excessive diagnosis and treatment， and serving as an alternative for patients who are unwilling or unfit for surgical treatment. At present， the optimal diagnosis and treatment strategy for pulmonary nodules has not been formed， which needs to be further studied from multiple perspectives such as clinical epidemiology， biology， and evidence-based medicine. The primary task of current research is to find out the advantages， effective prescriptions， and target populations and determine the effective outcomes of TCM in the treatment of pulmonary nodules. At the same time， basic research should be carried out to explore the etiology and biological behaviors of pulmonary nodules. The expert consensus on the diagnosis and treatment of pulmonary nodules with integrated TCM and Western medicine needs to be continuously revised to guide clinicians to conduct standardized， scientific， and accurate effective diagnosis and treatment.

Cold and heat belong to the eight-principal syndrome differentiation of traditional Chinese medicine， which can reflect the rise and fall of Yin and Yang in the body and the Yin and Yang nature of the disease. At present， traditional Chinese medicine has an inconsistent understanding of cold and heat in acute coronary syndrome. The emphasis on pathogenic factors of cold and heat is biased， and the elements of cold and heat syndrome are not fully reflected in the scale. Therefore， the literature has been reviewed from the perspectives of etiology， pathogenesis， symptom elements， and test signs with drugs. From the perspective of etiology， both cold evil and heat evil can increase the risk of acute coronary syndrome. It was previously believed that acute coronary syndrome occurs frequently in cold climates such as winter and spring. Based on this understanding， hot weather can also induce acute coronary syndrome， and different temperatures have different effects on patients of different ages and with different underlying diseases. In addition， artificial pathogenic factors such as excessive consumption of cold food and refrigeration air conditioners were added. From the perspective of pathogenesis， on the basis of the traditional ''asthenia in origin and asthenia in superficiality'' and ''phlegm stagnation''， it is found that Yin-cold and fire-heat can both cause paralysis of the heart chakra and pain induced by the blockage. The pathogenesis of acute coronary syndrome characterized by heat stagnation and coldness featuring heartburn should be distinguished from gastroesophageal reflux disease. Moreover， the pathogenesis of Yin cold coagulation and pulse stagnation and wind obstruction are different. The acute coronary syndrome is in line with the wind characteristics of frequent changes and can be treated with wind medicine. From the perspective of syndrome elements， the syndrome elements such as cold condensation， heat accumulation， and toxicity are analyzed， and the use of basic syndrome elements and their combination forms facilitates clinical and scientific research. In addition， according to the test sign with the drug， it can be seen that the attributes of cold and heat of traditional Chinese medicine prescriptions for acute coronary syndrome can be explained according to the temperature-sensitive transient receptor potential （TRP） ion channel， thus proving the pathogenesis of cold and heat of acute coronary syndrome.

Osteoporotic proximal humeral fracture (OPHF) is one of the common osteoporotic fractures in the aged, with an incidence only lower than vertebral compression fracture, hip fracture, and distal radius fracture. OPHF, secondary to osteoporosis and characterized by poor bone quality, comminuted fracture pattern, slow healing, and severely impaired shoulder joint function, poses a big challenge to the current clinical diagnosis and treatment. In the field of diagnosis, treatment, and rehabilitation of OPHF, traditional Chinese and Western medicine have accumulated rich experience and evidence from evidence-based medicine and achieved favorable outcomes. However, there is still a lack of guidance from a relevant consensus as to how to integrate the advantages of the two medical systems and achieve the integrated diagnosis and treatment. To promote the diagnosis and treatment of OPHF with integrated traditional Chinese and Western medicine, relevant experts from Orthopedic Expert Committee of Geriatric Branch of Chinese Association of Gerontology and Geriatrics, Youth Osteoporosis Group of Orthopedic Branch of Chinese Medical Association, Osteoporosis Group of Orthopedic Surgeon Branch of Chinese Medical Doctor Association, and Osteoporosis Committee of Shanghai Association of Integrated Traditional Chinese and Western Medicine have been organized to formulate Expert consensus on the diagnosis and treatment of osteoporotic proximal humeral fracture with integrated traditional Chinese and Western medicine ( version 2024) by searching related literatures and based on the evidences from evidence-based medicine. This consensus consists of 13 recommendations about the diagnosis, treatment and rehabilitation of OPHF with integrated traditional Chinese medicine and Western medicine, aimed at standardizing, systematizing, and personalizing the diagnosis and treatment of OPHF with integrated traditional Chinse and Western medicine to improve the patients ′ function.

Objective To observe the efficacy and safety of Morinda officinalis oligosaccharides in the continuation treatment of mild and moderate depression.Methods An open,single-arm,multi-center design was adopted in our study.Adult patients with mild and moderate depression who had received acute treatment of Morinda officinalis oligosaccharides were enrolled and continue to receive Morinda officinalis oligosaccharides capsules for 24 weeks,the dose remained unchanged during continuation treatment.The remission rate,recurrence rate,recurrence time,and the change from baseline to endpoint of Hamilton Depression Scale(HAMD),Hamilton Anxiety Scale(HAMA),Clinical Global Impression-Severity(CGI-S)and Arizona Sexual Experience Scale(ASEX)were evaluated.The incidence of treatment-related adverse events was reported.Results The scores of HAMD-17 at baseline and after treatment were 6.60±1.87 and 5.85±4.18,scores of HAMA were 6.36±3.02 and 4.93±3.09,scores of CGI-S were 1.49±0.56 and 1.29±0.81,scores of ASEX were 15.92±4.72 and 15.57±5.26,with significant difference(P＜0.05).After continuation treatment,the remission rate was 54.59％(202 cases/370 cases),and the recurrence rate was 6.49％(24 cases/370 cases),the recurrence time was(64.67±42.47)days.The incidence of treatment-related adverse events was 15.35％(64 cases/417 cases).Conclusion Morinda officinalis oligosaccharides capsules can be effectively used for the continuation treatment of mild and moderate depression,and are well tolerated and safe.

Objective China is among the 30 countries with a high burden of tuberculosis(TB)worldwide,and TB remains a public health concern.Kashgar Prefecture in the southern Xinjiang Autonomous Region is considered as one of the highest TB burden regions in China.However,molecular epidemiological studies of Kashgar are lacking. Methods A population-based retrospective study was conducted using whole-genome sequencing(WGS)to determine the characteristics of drug resistance and the transmission patterns. Results A total of 1,668 isolates collected in 2020 were classified into lineages 2(46.0%),3(27.5%),and 4(26.5%).The drug resistance rates revealed by WGS showed that the top three drugs in terms of the resistance rate were isoniazid(7.4%,124/1,668),streptomycin(6.0%,100/1,668),and rifampicin(3.3%,55/1,668).The rate of rifampicin resistance was 1.8%(23/1,290)in the new cases and 9.4%(32/340)in the previously treated cases.Known resistance mutations were detected more frequently in lineage 2 strains than in lineage 3 or 4 strains,respectively:18.6%vs.8.7 or 9%,P<0.001.The estimated proportion of recent transmissions was 25.9%(432/1,668).Multivariate logistic analyses indicated that sex,age,occupation,lineage,and drug resistance were the risk factors for recent transmission.Despite the low rate of drug resistance,drug-resistant strains had a higher risk of recent transmission than the susceptible strains(adjusted odds ratio,1.414;95%CI,1.023-1.954;P = 0.036).Among all patients with drug-resistant tuberculosis(DR-TB),78.4%(171/218)were attributed to the transmission of DR-TB strains. Conclusion Our results suggest that drug-resistant strains are more transmissible than susceptible strains and that transmission is the major driving force of the current DR-TB epidemic in Kashgar.

The compound (E)-1-(4-(3-(5-chloro-6-oxo-3,6-dihydropyridin-1(2H)-yl)-3-oxo-propyl-1-ene-1-yl) phenyl)-3-(4-fluorophenyl) urea (C12), a novel derivative of piperlongumine previously synthesized by our research group, was investigated in this study to examine its effects on human non-small cell lung cancer cell line H1299 in vitro and elucidate its potential mechanism of action. The impact of C12 on the proliferation, migration, and invasion abilities of H1299 cells were assessed using methyl thiazolyl tetrazolium (MTT) assay, wound healing assay, cloning formation assay, and Transwell assay. Flow cytometry was employed to evaluate the influence of C12 on cell cycle progression, reactive oxygen species (ROS) production, mitochondrial membrane potential (MMP), and apoptosis induction in H1299 cells. Western blot analysis was conducted to investigate the expression levels of p21, Cyclin B1, CDK1, Bax, Bcl-2, JNK, p-JNK, Erk1/2, p-Erk1/2, p38 and p-p38 proteins for exploring the anti-tumor mechanism underlying C12's actions. The results demonstrated that C12 exerted inhibitory effects on the proliferation, migration, and invasion capacities of H1299 cells in a time-dependent and concentration-dependent manner. Moreover, C12 induced G2/M phase arrest in the cell cycle, reduced MMP levels, elevated ROS production, and triggered apoptotic processes. Flow cytometry analysis revealed that C12 downregulated Cyclin B1 and CDK1 protein expressions, resulting in G2/M phase arrest. C12 also upregulated Bax/Bcl-2 ratio, promoting apoptosis. Furthermore, C12 activated MAPK signaling pathway by enhancing phosphorylation levels of JNK, Erk1/2, and p38 proteins. In conclusion, C12 significantly suppressed proliferation, migration, and invasion capabilities while inducing cell cycle arrest and apoptosis in H1299 cells. These effects may be attributed to activation of the MAPK signaling pathway.

This paper applied gas chromatography-mass spectrometry (GC-MS), network pharmacology and nuclear magnetic resonance hydrogen spectroscopy (¹H NMR) metabolomics techniques to study the material basis and mechanism of action of Ning Shen Essential Oil in anti-insomnia. The main volatile components of Ning Shen Essential Oil were analyzed by gas chromatography-mass spectrometry (GC-MS), and the insomnia-related targets were predicted using the Traditional Chinese Medicine Systematic Pharmacology Database and Analytical Platform (TCMSP) and the databases of GeneCards, OMIM and Drugbank. The insomnia model of rats was replicated by intraperitoneal injection of 4-chloro-DL-phenylalanine (PCPA). Animal experiments were approved by the Animal Ethics Committee of Shandong University of Traditional Chinese Medicine (Ethics No.: SDUTCM20221025010). The modulating effect of Compound Ning Shen Essential Oil on anxiety behavior of rats was evaluated by behavioral related indexes. The serum levels of corticotropin-releasing hormone (CRH), adrenotropic corticotropic hormone (ACTH) and melatonin (MT) were measured by enzyme-linked immunoassay (ELISA). Rat serum and hippocampus were taken for nuclear magnetic resonance (¹H NMR) metabolomics to detect the changes of endogenous metabolites in rat serum hippocampus, to designate the differential metabolites and to construct metabolic pathways. The results showed that the exercise distance in the open field experiment and the number of times and time to enter the open arm in the elevated cross maze experiment of the rats in the model group were significantly reduced (P < 0.05, P < 0.01). The behavioral indexes of rats improved to different degrees after the administration of Ning Shen Essential Oil. The serum CRH and ACTH levels of rats in the model group increased significantly (P < 0.05, P < 0.01), and the MT level decreased significantly (P < 0.01); After the intervention, serum CRH and ACTH levels were reduced to different degrees, and MT levels could be regressed. ¹H NMR metabolomics screened 10 potential biomarkers related to insomnia, which involved in 6 potential metabolic pathways. A total of 35 components of Ning Shen Essential Oil were detected by GC-MS, the main component targets of Ning Shen Essential Oil and insomnia disease targets were intersected, a total of 172 intersecting genes were screened, and 26 core targets were identified. The study demonstrated that Ning Shen Essential Oil had protective effects against PCPA-induced insomnia in rats, which was probably correlated with regulation of the hypothalamic-pituitary-adrenal axis (HPA) related hormones and metabolism of amino acids, lipids and choline.

Objective:To clarify the causal relationship between obesity and male infertility through Mendelian randomization(MR)study.Methods:We assessed the causal effect of genetically predicted body mass index(BMI)on the risk of male infertility via a two-sample MR analysis,with the BMIs of 99 998 cases and 12 746 controls as the exposure factor and genetic information on male infertility obtained from a genome-wide association study of 73 479 Europeans.In the univariable MR(UVMR)analysis of the causal relationship,we mainly used inverse variance weighting(IVW),with MR-Egger regression and weighted median filtering as the supplementary methods.Sensitivity analyses including the Cochran's Q test,Egger intercept test,MR-PRESSO,leave-one-out analysis and funnel plot were performed to verify the robustness of the MR results.To evaluate the direct causal effects of BMI on MI risk,mult-ivariable MR(MVMR)was performed.Results:UVMR indicated a causal relationship between genetically predicted BMI and an in-creased risk of male infertility(OR:1.237,95%CI:1.090-1.404,P=0.001).Sensitivity analysis revealed little evidence of bias in the current study(P>0.05).With such risk factors as type 2 diabetes,alcohol consumption and smoking adjusted,MVMR confirmed a direct causal effect of genetically predicted BMI on the risk of male infertility(P<0.05).Conclusion:Genetically pre-dicted BMI may be associated with an increased risk of male infertility.Further studies are expected to explore the underlying mecha-nisms of this association and provide some new strategies for the prevention and treatment of BMI-related male infertility.

Objective:To investigate the clinical application value of liquid wound dressing in circumcision.Methods:This retrospective study included 200 cases of redundant prepuce or phimosis undergoing circumcision in the Affiliated Hospital of Nanjing University of Chinese Medicine between August 2021 and December 2022.We divided the patients into two groups of an equal number to receive wound care with liquid wound dressing(the observation group)and iodine gauze dressing(the control group),respectively.We compared the operation time,postoperative bleeding,edema,infection,incision exudation and scarring,and pain scores during dressing change at 4,24 and 72 hours after surgery.Results:No statistically significant differences were observed between the ob-servation and control groups in the operation time([16.22±3.15]vs[17.01±3.37]min,P＞0.05)or postoperative bleeding(12 vs 14 cases,P＞0.05).The patients in the observation group,compared with the controls,showed significantly lower incidences of postoperative edema(9 vs 23 cases),infection(6 vs 17 cases),incision exudation(7 vs 21 cases)and scarring(5 vs 14 cases),and lower pain scores during dressing change at 4 hours(6.71±1.02vs7.04±0.92),24 hours(5.38±1.45 vs 5.87±1.35)and 72 hours after surgery(3.65±1.53 vs 4.26±1.63)(all P＜0.05).Conclusion:For postoperative wound care of the patients undergoing circumcision,liquid wound dressing can evidently reduce postoperative pain,incision bleeding,edema,infection and scarring,and therefore deserves clinical promotion.
