OBJECTIVE: To observe the clinical effect of needle cauterization on vitiligo with deficiency cold and blood stasis. METHODS: A total of 62 patients of vitiligo with deficiency cold and blood stasis were randomly divided into an observation group and a control group, 31 cases each group.On the basis of 308 nm excimer light irradiation combined with ironing with Chinese medicine, the control group was treated with tacrolimus ointment for external use, twice a day; the observation group was treated with needle cauterization at vitiligo spots, once a week.Both groups were treated for 10 weeks. Before and after treatment, the area of vitiligo spot, TCM syndrome score, serum levels of inflammatory indexes (interleukin[IL]-6 and IL-17) were observed in the two groups, and the clinical effect was evaluated. RESULTS: After treatment, the areas of vitiligo spot, TCM syndrome scores and serum levels of IL-6, IL-17 were decreased compared with those before treatment in both groups (P<0.05), and the above indexes in the observation group were lower than those in the control group (P<0.05). The total effective rate in the observation group was 93.5% (29/31), which was higher than 77.4% (24/31) in the control group (P<0.05). CONCLUSION Needle cauterization could reduce the areas of vitiligo spot in patients of vitiligo with deficiency cold and blood stasis, improve the clinical symptoms, its mechanism may be related to the reduction of serum levels of inflammatory indexes.

Bone morphogenetic proteins (BMPs) are multifunctional growth factors of the transforming growth factor β (TGF-β) superfamily. They regulate steroid secretion from mammalian granulosa cells, promote granulosa cell survival and proliferation, and inhibit follicular atresia, luteinization, and granulosa cell apoptosis, thereby promoting the development and maturation of mammalian follicles. At the same time, BMPs play an important role in embryonic morphogenesis, induction of uterine receptivity, and blastocyst attachment. This paper describes the effects of BMPs on mammalian follicular and embryonic development and the roles of BMPs in female reproduction, focusing on the process in which BMPs promote follicular maturation by regulating steroid secretion from granulosa cells during mammalian oocyte maturation. This review aims to provide a reference for further research on mammalian oocyte culture and improvement of reproductive efficiency in female animals.

ObjectiveTo investigate the current status and related factors of maternal influenza vaccination willingness among pregnant and postpartum women in Shanghai and Liaoning Province, China, and to explore the facilitators and barriers affecting vaccination uptake, so as to provide references for future practices in promoting maternal influenza immunization in China. MethodsA convergent mixed-methods research was conducted. From January to March 2024, a questionnaire survey was conducted among women attending prenatal and postnatal care at 7 medical institutions in Shanghai and Dalian, Liaoning Province, which aimed to assess pregnant women’s knowledge about influenza vaccine and their willingness to vaccination during pregnancy, as well as to identify the related factors. In addition, purposive sampling method was used to conduct in-depth interviews with pregnant women and perinatal healthcare service providers to explore their perspectives on influenza vaccination during pregnancy, including the reasons for their willingness or unwillingness to receive ( or recommend) the vaccine, and the relevant facilitators and barriers to vaccination. ResultsA total of 366 pregnant and postpartum women participated in the questionnaire survey, and 9.56% (35/366) of them were willing to receive the influenza vaccine during pregnancy. The results of multivariate logistic stepwise regression analyses showed that primipara (aOR=0.158, 95%CI: 0.037‒0.671, P=0.012), family members’ support for influenza vaccination during pregnancy (aOR=0.015, 95%CI: 0.003‒0.082, P<0.001) were associated with higher willingness to receive influenza vaccine during pregnancy. Absence of influenza infection during pregnancy (aOR=5.383, 95%CI: 1.801‒16.092, P<0.001), and lack of knowledge regarding influenza vaccination during pregnancy (aOR=11.294, 95%CI: 3.593‒35.496, P<0.01) were associated with lower willingness to receive influenza vaccine during pregnancy. Qualitative findings indicated that the facilitators to vaccination willingness among pregnant and postpartum women included the recommendation of healthcare service providers, adequate knowledge of influenza vaccine information and family members’ support for vaccination. Conversely, the barriers to vaccination willingness included low recommendation from the healthcare service providers, lack of knowledge about the safety of influenza vaccine during pregnancy and inadequate attention to influenza and influenza vaccine. ConclusionThe willingness to receive influenza vaccination among pregnant and postpartum women in Shanghai and Liaoning Province is relatively low. It is recommended that China should promptly improve the evidence-based system for the safety and efficacy of influenza vaccines for pregnant and postpartum women, along with an establishment of the mechanism for addressing adverse reactions. Furthermore, it is essential to enhance educational outreach to pregnant and postpartum women, their families, and healthcare service providers, thereby increasing the accessibility of information regarding influenza vaccination, which are expected to enhance the willingness of pregnant and postpartum women to receive the vaccine.

Objective To explore the expression of serum bone morphogenetic protein 2(BMP2),bone morphogenetic protein 7(BMP7)level and its association with left ventricular hypertrophy(LVH)among patients with chronic kidney disease(CKD).Methods A total of 93 CKD patients admitted to Yan'an People's Hospital from June 2019 to June 2023 were collected as CKD group,divided into LVH group(n=34)and non-LVH group(n=59)according to whether concurrence was combined with LVH.A total of 60 healthy volunteers were selected as control group in the same period.The clinical data were collected and serum BMP2 and BMP7 levels were detected by enzyme-linked immunosorbent assay(ELISA).The association between serum BMP2,BMP7 and CKD stage was analyzed by Spearman's rank correlation analysis.Logistic regression analyze was performed to analyze the influencing factors of CKD patients with concomitant LVH.ROC curves were plotted to assess the diagnostic value of serum BMP2,BMP7 on LVH.Results Serum BMP2(106.09±19.34 pg/ml)in CKD group was higher than that in control group(83.76±15.27 pg/ml),and serum BMP7(15.16±4.92 pg/ml)in CKD group was lower than that in control group(26.53±5.80 pg/ml),the differences were statistically significant(t=7.559,13.002,all P<0.05).Serum BMP2 was sequentially increased in patients with CKD stages Ⅰ,Ⅱ,Ⅲ,Ⅳ and Ⅴ(90.32±6.04,98.56±6.63,110.32±7.49,121.13±7.82,131.81±7.97 pg/ml),and serum BMP7 was sequentially decreased (20.06±2.79,17.01±2.22,13.34±2.18,11.20±2.01,9.35±2.09 pg/ml),and the differences were statistically significant(F=19.863,11.567,all P<0.05).Serum BMP2 was positively correlated with CKD stage(r=0.592,P<0.05),while serum BMP7 was negatively correlated with CKD stage(r=-0.603,P<0.05).BMP2 was an independent risk factor for LVH in CKD patients[OR(95％CI):1.640(1.317～2.043),P<0.05].BMP7 was a protective factor for LVH in CKD patients[OR(95％CI):0.521(0.349～0.779),P<0.05].Both serum BMP2 and BMP7 had diagnostic value for LVH with AUC(95％CI)of 0.782(0.719～0.832)and 0.791(0.726～0.859),respectively.The AUC(95％CI)of the combination of two indicators was 0.873(0.812～0.930),which was greater than that of single indicator(Z=2.357,2.027,all P<0.05).Conclusion BMP2 is abnormally elevated and BMP7 is abnormally decreased in CKD patients,and the abnormal expression of two indicators is associated with CKD disease and LVH.Early combined detection of two indexes can be used as an indicator for diagnosing LVH.

Objective To explore the accuracy and clinical application value of artificial intelligence(AI)-based coronary computed tomography angiography(CCTA)in the evaluation of coronary artery stenosis in patients with acute coronary syndrome(ACS).Methods Fifty-four patients with suspected ACS who underwent CCTA examination and invasive coronary angiography(ICA)within 72 h were retrospectively selected.The CCTA images of all patients were processed by AI(AI group)and manual post-pro-cessing(manual group),respectively.The image quality,work efficiency and detection rate of coronary artery stenosis were compared between AI group and manual group.With ICA results as the gold standard,the sensitivity,specificity,positive predictive value,negative predictive value and accuracy of AI in the diagnosis of ACS patients with coronary artery stenosis(≥50％)in CCTA were analyzed,and the consistency of AI and ICA examination results was tested.Results The image quality of CCTA in AI group(grade Ⅰ 27.8％)was better than that in manual group(grade Ⅰ 14.8％),but there was no statistical difference between the two groups(X2=2.707,P＞0.05).The average diagnosis time of AI group(89.67 s±33.21 s)was significantlyshorter than that of manual group(813.33 s±301.84 s)and the difference was statistically significant(t=-17.512,P＜0.001),and the average time gain rate was 88.97％.There was no statistical difference in the detection rate of coronary artery stenosis(≥50％)between AI group and manual group(x2=0.003,P＞0.05).The sensitivity,specificity,positive predictive value,negative predictive value,and accuracy of AI in diagnosis of ACS were 87.60％,96.44％,80.30％,97.92％,and 95.19％,respectively,which were significantly consistent with the results of ICA examina-tion(Kappa=0.810,P＜0.05).Conclusion AI-assisted diagnosis can correctly identify the coronary artery tree with better image,significantly shorten the diagnosis time of CCTA in ACS patients with high accuracy,and can provide a strong basis for the early treat-ment of patients with acute chest pain.

Tripterygium wilfordii is widely used in the treatment of immune system disease and has a remarkable curative effect. Triptolide and Tripterygium glycosides are the most commonly used active ingredients in clinical practice， but their treatment window is narrow and there are many side effects. The damage involves the reproductive system， blood system， cardiovascular system， digestive system， etc. Based on clinical observations and literature summaries， the symptoms of adverse reactions mostly occur in the digestive system （liver and gastrointestinal tract）. Relevant scholars have launched a lot of studies of the manifestations of liver injury induced by T. wilfordii and the mechanism of liver injury. The mechanism is mainly related to liver cell apoptosis， induction of oxidative stress， immune injury， excessive autophagy of liver cells， abnormal fatty acid metabolism， and abnormal enzyme metabolism in liver tissues. This article reviewed and summarized relevant literature on gastrointestinal injury caused by T. wilfordii， but there are few studies on the manifestations and mechanisms of adverse reactions， which still need further research by scholars. In addition， this article also summarized the research on how to reduce toxicity and enhance efficacy of prescriptions prepared from T. wilfordii in the digestive system， mainly involving compatibility with western medicines （Methotrexate， Leflunomide， Iguratimod， etc.）， use along or combination with Chinese medicines （single Chinese medicine， Chinese medicine monomers， and Chinese medicine compounds）， acupuncture and moxibustion （electroacupuncture and moxibustion）， dosage form improvement （glycol plastid gel， self-dissolving microneedle， solid lipid nanoparticles， gastric floating sustained-release capsules， etc.）， processing （steaming， stir-frying， radish seed processing， money grass processing， licorice processing， etc.）， and other methods to reduce toxicity. To sum up， this article analyzed the manifestations， mechanisms， and methods of reducing toxicity and enhancing efficacy of T. wilfordii-induced liver injury and gastrointestinal injury by sorting out relevant literature， in order to provide a reference for the clinical application of T. wilfordii and some research ideas for the future in-depth study of T. wilfordii-induced digestive system injury.

Objective To investigate the potential effect and mechanism of curcumin in inhibiting synaptic injury in the cortex of rats with cerebral ischemia-reperfusion. Methods Sprague-Dawley rats were divided into sham-operated group, model group, low-dose curcumin (50 mg/kg) group, and high-dose curcumin (100 mg/kg) group. A model of middle cerebral artery occlusion for 2 hours and reperfusion for 24 hours was constructed, and curcumin was administered. Based on the neurological function score, the effects of curcumin on cerebral infarct volume, synaptic ultrastructure changes, inflammatory cell infiltration, and the expression of NLRP3, Caspase-1, Synapsin1, and CAMKⅡ were observed after the end of the animal treatment. Results The neurological function scores were 0, 3.25±0.43, 2.50±0.50, and 1.50±0.50 for the sham-operated group, model group, low-dose curcumin group, and high-dose curcumin group, respectively. The percentage of cerebral infarct volume was 0, (38.89±2.21)%, (33.48±1.77)%, and (23.69±2.19)%, respectively. Compared with the sham operation group, the model group had severe synaptic ultrastructure damage, extensive inflammatory cell infiltration, significantly increased expression of Caspase-1 and NLRP3 (P < 0.5), and significantly decreased expression of Synapsin1 and CAMKⅡ (P < 0.5). Curcumin treatment significantly inhibited synaptic damage, reduced inflammatory cell infiltration, decreased the expression of Caspase-1 and NLRP3 (P < 0.5), and increased the expression of Synapsin1 and CAMKII (P < 0.5), when compared with the model group. Conclusion Ischemia-reperfusion-mediated synaptic injury in rat brain triggers an inflammatory response in cortical nerve cells, and curcumin alleviates synaptic damage and reduces brain injury by inhibiting inflammatory factor levels.

Objective To detect the serum levels of CC chemokine receptor 2(CCR2)and C-reactive pro-tein(CRP)in stroke patients,and analyze their relationship with the severity of stroke associated pneumonia and their clinical significance.Methods A total of 78 patients with stroke associated pneumonia who were di-agnosed and treated in the hospital from October 2022 to February 2023 were collected as the study group,ac-cording to the severity of pneumonia,the study group was divided into mild group(31 cases),moderate group(29 cases),and severe group(18 cases),78 stroke patients who did not develop pneumonia were included into control group.Pearson method was applied to analyze the correlation between serum CCR2 and CRP levels in stroke associated pneumonia patients.Multivariate Logistic regression was applied to analyze the factors influ-encing the occurrence of stroke associated pneumonia.Receiver operating characteristic(ROC)curve was ap-plied to analyze the diagnostic value of serum CCR2 and CRP for stroke associated pneumonia.Results The National Institute of Health stroke scale(NIHSS)score,serum CCR2,and CRP levels in the study group were obviously higher than those in the control group(P<0.05).The levels of serum CCR2 and CRP increased with the aggravation of pneumonia(P<0.05).The levels of serum CCR2 and CRP in the study group were positively correlated(r=0.799,P<0.05).NIHSS score,CCR2,and CRP levels were risk factors for stroke associated pneumonia in stroke patients(P<0.05).The area under the curve(AUC)for the diagnosis of stroke associated pneumonia using serum CCR2 and CRP alone was 0.873 and 0.888,respectively,and the AUC for the combined detection of the two was 0.936,the combined detection of the two was superior to the individual detection of serum CCR2 and CRP(Zcombination-CCR2=1.987,Zcombination-CRP=1.832,P=0.041,0.047).Conclusion Serum CCR2 and CRP are closely related to the severity of stroke associated pneumonia,and their combined detection has high diagnostic value for stroke associated pneumonia.

ObjectiveTo reveal the pharmacodynamic substances for the anti-inflammatory and analgesic effects of Glycyrrhizae Radix et Rhizoma by structure-activity omics. MethodOn the basis of the previous study about the screening of active components in vitro， this study explored the effects of flavonoids in Glycyrrhizae Radix et Rhizoma in vivo. The flavonoids in Glycyrrhizae Radix et Rhizoma and their direct targets for the anti-inflammatory and analgesic effects were obtained from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform （TCMSP）， PharmMapper， Swiss TargetPrediction， DisGeNET， and Online Mendelian Inheritance in Man （OMIM）. STRING and Cytoscape 3.7.2 were employed to establish the protein-protein interaction （PPI） network of key targets. Molecular docking was performed to simulate the binding of five targets with high degrees to flavonoids in Glycyrrhizae Radix et Rhizoma， on the basis of which the key core targets were selected. The targets were used as a bridge to correlate the structures and effects of one or more classes of chemical components in Glycyrrhizae Radix et Rhizoma. According to the binding affinity between flavonoids with different structures in Glycyrrhizae Radix et Rhizoma and targets， the relationships between compound structures and core targets were discussed. ResultThe flavonoids in Glycyrrhizae Radix et Rhizoma reduced the content of prostaglandin E₂ （PGE₂） in the rat model of pain induced by formalin， demonstrating definite anti-inflammatory and analgesic effects. Sixty active compounds （flavonoids） with anti-inflammatory and analgesic effects of Glycyrrhizae Radix et Rhizoma were obtained. With the total score as the standard， prostaglandin-endoperoxide synthase 2 （PTGS2） and mitogen-activated protein kinase 3 （MAPK3） were selected as the key core targets of Glycyrrhizae Radix et Rhizoma for the anti-inflammatory and analgesic effects. Except that flavones showed selectivity of binding to MAPK3， the other flavonoids of Glycyrrhizae Radix et Rhizoma showed strong binding to PTGS2 and MAPK3， and the structures containing glycoside fragments showed stronger binding affinity to the targets. The introduction of chain olefins in the ring of chalcones facilitated the binding to the targets. The isopentenyl fragment in flavonols may cause the difference in binding affinity. The parallel combination of a ring into pyran ring in flavanes was not conducive to the binding to the target. The electric charge， liposolubility， and steric hindrance of the substituent group on the B ring of isoflavones directly affected the binding affinity. ConclusionThis study adopts structure-activity omics to analyze the material basis for the anti-inflammatory and analgesic effects of Glycyrrhizae Radix et Rhizoma. Structure-activity omics provides new ideas and methods for predicting the pharmacodynamic substances of traditional Chinese medicine.
