BACKGROUND:Cervical rotation-traction manipulation is effective and safe in the treatment of cervical spondylotic radiculopathy,and has been widely used in clinical work.However,its effects on the biomechanics of cervical vertebra and intervertebral disc and the area of intervertebral foramen have not been systematically clarified. OBJECTIVE:Based on the finite element analysis technique,a relevant research and analysis were carried out to provide digital evidence for the mechanism of effect of cervical rotation-traction manipulation in the treatment of cervical spondylotic radiculopathy. METHODS:The CT image data of a volunteer with no neck diseases were selected as the finite element model material at its left-handed physiological limit position.The initial construction of the finite element model was completed by Mimics 19.0 software,Geomagic Studio 2013 software,Hypermash 14.0 software,and ANSYS Workbench 2020 R2 software,respectively.Based on the literature,the grid division of cervical structure and the assignment of elastic modulus and elastic coefficient were completed.Based on the previous work of the team,the mechanical effects of cervical rotation-traction manipulation were simulated on the model.Effects of cervical rotation-traction manipulation on the mechanical parameters of each vertebral body and intervertebral disc in C3-T1 segment and on the cervical lateral foramen area were analyzed. RESULTS AND CONCLUSION:(1)During cervical rotation-traction manipulation,the stress of bone structure was significantly higher than that of soft tissue such as intervertebral disc.(2)When operating the technique,the stress at the top of each cervical vertebra was higher,the stress at the bottom was lower,and the stress at the facet joint and transverse process was lower.The stress at the top of the intervertebral disc was lower,the stress at the bottom was higher,but the highest point of the intervertebral disc stress was outside the top.(3)In addition,after loading the lifting force,the projected area of the C6/C7 intervertebral foramen increased significantly compared with that before loading.(4)It is indicated that the cervical rotation-traction manipulation has the mechanical characteristics of changing the stress structure of the cervical spine itself,and can expand the C6/7 intervertebral cervical foramen area on the opposite side of the patient's cervical rotation,so as to achieve the purpose of treating cervical spondylotic radiculopathy.

ObjectiveTo investigate the effect of Qingrun prescription(QRP)-containing serum on improving insulin resistance in HepG2 cells and its potential mechanisms. MethodsAn insulin resistance model was established in HepG2 cells with 1×10-6 mol·L-1 insulin. Branched-chain α-keto acid dehydrogenase (BCKDH) gene silencing was achieved using siRNA, and the cells were divided into 8 groups: normal group, model group (1×10-6 mol·L-1 insulin), metformin group (1 mmol·L-1 metformin), high-, medium-, and low-dose QRP groups (20%, 10%, and 5% QRP-containing serum, respectively), QRP + siRNA-silenced BCKDH (si-BCKDH) group (10% QRP-containing serum + si-BCKDH), and QRP + si-NC group (10% QRP-containing serum + si-NC). Glucose levels in the supernatant were measured with a glucose assay kit, while glycogen content was assessed using a glycogen assay kit. Levels of branched-chain amino acids (BCAAs) and branched-chain keto acids (BCKAs) were determined using ultra-high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS). mRNA transcription and protein expression levels of BCKDH, dishevelled, Egl-10, and pleckstrin (DEP) domain-containing mammalian target of rapamycin (mTOR)-interacting protein (DEPTOR), mTOR, and ribosomal protein S6 kinase 1 (S6K1) were detected using real-time quantitative polymerase chain reaction (Real-time PCR) and Western blot. ResultsCompared to the normal group, the model group exhibited significantly decreased glucose consumption and glycogen content, increased levels of BCAAs and BCKAs, downregulated expression of BCKDH and DEPTOR, and upregulated mTOR and S6K1 expression (P<0.01). In comparison to the model group, QRP treatment at all doses significantly enhanced glucose consumption and glycogen content while reducing BCAAs and BCKAs levels (P<0.01). The high- and medium-dose QRP groups demonstrated significant upregulation of BCKDH mRNA transcription and protein expression, as well as DEPTOR mRNA transcription. Moreover, the DEPTOR protein expression level was significantly increased in high-, medium-, and low-dose QRP groups, while mTOR and S6K1 mRNA and protein expression levels were markedly downregulated (P<0.05, P<0.01). Compared to the QRP + si-NC group, the QRP + si-BCKDH group exhibited increased BCAAs and BCKAs levels, significantly decreased BCKDH mRNA transcription and protein expression, downregulated DEPTOR mRNA and protein expression, and upregulated mTOR and S6K1 mRNA and protein expression (P<0.05, P<0.01). ConclusionQRP may improve insulin resistance by reprogramming BCAAs metabolism. This effect involves upregulating BCKDH, reducing BCAAs and BCKAs levels, and suppressing the mTOR pathway activation.

OBJECTIVE To establish management index system for rational drug use of key monitoring drugs, and provide reference for the management of key monitoring drugs in the hospitals. METHODS First, the management index system for rational drug use of key monitoring drugs was drafted by collecting the evidence from related medical literature. Next, using a modified Delphi method, twenty experienced experts from the fields of pharmacy, medical practice, healthcare insurance, and finance were selected to participate in two rounds of questionnaire consultations. Based on the expert enthusiasm coefficient, authority coefficient, degree of opinion concentration, and degree of coordination, the final indicators were determined to establish a management index system for rational drug use of key monitored drugs in medical institutions. RESULTS The expert enthusiasm coefficients reached 100% in both rounds of consultation. In first-level, second-level and third-level indicators, the authority coefficients of experts were 0.89, 0.86 and 0.87, and coordination coefficients of the experts in importance score were 0.300 (P< 0.05), 0.125 (P<0.05) and 0.139 (P<0.05), respectively. The average score for the importance of all indicators reached over 3.5, in which the full score ratio ranged from 35% to 100%. Except that the variation coefficient of a third-level indicator “number of specifications purchased for key monitored drugs” was 0.26, the variation coefficients of rest indicators were less than or equal to 0.25. Based on the results of expert consultation, final version of the management index system established in this study, including two first-level indicators (drug procurement and use, and rational drug use), five second-level indicators (such as the accessibility, cost-effectiveness) and twenty third-level indicators (such as the number of specifications purchased for key monitored drugs, the increase in the cost of key monitored drugs). CONCLUSIONS The management index system established in this study possesses high reliability and strong operability, and may provide a reference for the management of key monitoring drugs in the hospitals.

ObjectiveTo explore the potential mechanism of action of the combination of Sanguisorbae Radix-Sophorae Flos (DH) in the treatment of ulcerative colitis (UC) using network pharmacology methods and molecular docking technology. MethodsNetwork pharmacology analysis was utilized to predict the potential targets of DH for the treatment of UC. The therapeutic effects were experimentally validated by inducing a UC model in mice with 3% dextran sulfate sodium (DSS). The experimental groups were the normal group, the model group, the salazosulfapyridine group (100 mg·kg-1), and the low, medium, and high dose groups of DH (1.2, 2.4, and 4.8 g·kg-1). The efficacy of the treatment was assessed through the general condition of the mice, histopathological examination, and the expression levels of inflammatory markers in the colon. The effect of DH on angiogenesis was explored by messenger RNA (mRNA) detection of colonic angiogenesis-related mediators, vascular endothelial growth factor (VEGF) immunohistochemistry, microvessel density (MVD) detection, and transmission electron microscopy. The phosphatidylinositol-3-kinase (PI3K)-protein kinase B (Akt) signaling pathway proteins were quantitatively analyzed through Western blot to assess whether the suppression of pathological angiogenesis by DH is associated with this pathway. ResultsNetwork pharmacological analysis yielded 112 potential core therapeutic targets for the treatment of UC with DH, of which the core targets were tumor protein 53 (TP53), JUN, interleukin (IL)-6, Akt1, and tumor necrosis factor (TNF). Compared with the normal group, mice in the model group showed significant weight loss, colon shortening, and high DAI score, increased expression of inflammatory factors IL-6, IL-1β, and TNF-α, as well as increased mRNA expression levels of angiogenesis-related mediators VEGF, vascular cell adhesion molecule 1 (VCAM1), angiotensin 1 (Ang1), matrix metalloproteinase (MMP)-1, MMP-2, and MMP-9. The positive expression of CD31 and VEGF in colonic tissue increased, and the protein expression of the PI3K/Akt pathway was increased (P<0.05). The endothelial cells of the colonic mucosa and the colonic vasculature were severely damaged. Compared with the model group, mice in the DH groups had significantly reduced weight loss and colon shortening, lower DAI scores, and a significant decrease in mRNA expression of inflammatory factors and angiogenesis-related mediators. In addition, there was decreased positive expression of CD31 and VEGF in colonic tissue and decreased protein expression of the PI3K/Akt pathway (P<0.05). ConclusionNetwork pharmacology, molecular docking, and experimental validation are applied to explore the mechanism of action of DH in the treatment of UC, and it is found that DH is able to improve the symptoms of colitis and inhibit the pathological angiogenesis in UC mice. Its action might be related to affecting the PI3K/Akt pathway.

Green prescription is a written prescription aimed at improving health by promoting physical activity and improving diet, with advantages such as high cost-effectiveness, strong feasibility, and minimal harm to patients. The theory of traditional Chinese medicine (TCM) green prescription integrates the health philosophy of "following rule of yin and yang, and adjusting ways to cultivating health", the exercise philosophy of balancing yin-yang and the five elements, and the dietary philosophy of moderation and balance, which embody core TCM concepts such as treating disease before its onset and harmony between humans and nature. It has also developed traditional exercise practices like Tai Chi, Baduanjin, Wuqinxi, Yi-Gin-Ching, and Qigong, as well as dietary adjustments like medicated diet and herbal wines. However, it is believed that the TCM green prescription currently suffers from insufficient evidence-based research, low patient awareness and acceptance, and weak basic research. Based on this, it is proposed that large-sample clinical trials should be conducted in the future to improve the quality of evidence-based medicine, basic research can be carried out with the help of artificial intelligence and other methods in research design, the hospital information system (HIS) can be used for control at the implementation level, and publicity and patient education can be strengthened through the new media, so as to promote the development and application of the TCM green prescriptions in the field of global health treatment.

OBJECTIVE To construct the drug utilization evaluation criteria for Dezocine injection, so as to provide reference for the rational drug use in medical institutions. METHODS On the basis of evidence methodology, relevant guidelines/expert consensus, systematic reviews/meta-analysis were consulted; the evaluation criteria framework for Dezocine injection was established after screening evidence. Delphi method was employed, whereby 28 clinicians and clinical pharmacists from secondary and above-level medical institutions across eight provinces, including Tianjin, Beijing and Shandong, were selected to participate in two rounds of questionnaire surveys. The final indicators were determined based on the experts’ enthusiasm coefficient, authority coefficient, and degree of coordination. RESULTS The effective recovery rate of questionnaire was 100% in the first round and 92.86% in the second round; expert authority coefficient was 0.82 in the first round and 0.81 in the second round; the coordination degree of experts in the first round was 0.29, and in the second round was 0.31 (P<0.001). Drug utilization evaluation standard system for Dezocine injection was formed finally, including three dimensions of medication indications, medication process and medication results, with a total of 11 first-level indicators (such as indications, usage and dosage) and 33 second-level indicators (such as labor analgesia and the management of severe pain following major or moderate surgeries combined with other analgesic drugs). The average importance scores for each indicator ranged from 4.08 to 5.00 points, with an overall average score of 4.61 points and coefficient of variation ranging from 0 to 0.19. CONCLUSIONS The drug utilization evaluation criteria for Dezocine injection established based on evidence-based methodology and Delphi method is authoritative and scientific, which provides a reference for subsequent evaluation of the rationality of clinical medication.

ObjectiveTo investigate the trend and influencing factors of newly reported human immunodeficiency virus (HIV) positivity rate among men who had sex with men (MSM) in Shanghai from 2021 to 2024, and to provide evidence for formulating scientific prevention and control measures of AIDS. MethodsMultiple rounds of cross-sectional questionnaire surveys were conducted among MSM by Shanghai Qing’ai Health Promotion Center. Pearson and Cochran-Armitage trend χ2 tests were used to analyze the differences and changes in population characteristics and newly reported HIV positivity rates. A logistic regression model was applied for multivariate analyses of factors associated with newly reported HIV positivity. ResultsA total of 1 653 MSM who had not been previously diagnosed with HIV infection were surveyed. The newly reported HIV positivity rates in 2021, 2023, and 2024 were 7.87%, 3.91%, and 3.06%, respectively, showing a decreasing trend (χ2trend=13.460, Ptrend<0.001). Multivariate analyses revealed that MSM aged 18‒<25 years, residing locally for <1 year, identifying as bisexual, lacking HIV knowledge, and having ≥10 same-sex partners in the past 6 months exhibited higher newly reported HIV positivity rates. Conversely, MSM knowledgeable about HIV prevention, residing locally for 1‒5 years, and engaging in oral sex with male partners in the past 6 months demonstrated lower HIV positivity rates. Annual analyses revealed that MSM with HIV knowledge had lower newly reported HIV positivity rates in 2023 and 2024 (aOR=0.300, 95%CI: 0.811‒0.111; aOR=0.202, 95%CI: 0.085‒0.483). ConclusionThe newly reported HIV positivity rate among MSM in Shanghai from 2021 to 2024 showed a decline. Future interventions should focus on young and mobile MSM, strengthen HIV knowledge education through platforms such as the internet, promote safe sexual behaviors and regular testing, and further expand the coverage of pre-exposure prophylaxis (PrEP) and post-exposure prophylaxis (PEP) to control HIV transmission within this population.
