In order to clarify material basis of effective parts of liangxue tongyu prescription, blood-heat and blood-stasis rat model induced by dry yeast was established. The changes of rectal temperature, blood viscosity and plasma viscosity were used to evaluate the cooling-blood and activating-blood effects of liangxue tongyu prescription and its parts. Compared with the model group, the extract from liangxue tongyu prescription, its volatile oil and n-butanol part could significantly reduce rectal temperature (P<0.01), and also reduce blood viscosity and plasma viscosity to various degrees (P<0.01 or P<0.05). So volatile oil and n-butanol part were primarily identified as effective parts of liangxue tongyu prescription. By using GC-MS with normalization method of area to analyze volatile oil of liangxue tongyu prescription, 70 compounds were identified, accounting for about 92.54%, mainly as β-asarone, paeonol, α-asarone and shyobunone. 42 compounds such as peony glycosides, tannins, and iridoid glycosides were identified by HPLC-MS techniques and standard comparison. The study determined the effective parts of liangxue tongyu prescription and clarified the chemical composition providing the foundation for further studies on material basis of liangxue tongyu prescription.

Objective: To investigate the epidemic status and influencing factors of colorectal polyps among urban residents in Lanxi. Methods: A representative urban community was selected from Lanxi. A total of 935 local residents aged 18-80 years received questionnaire survey,physical examination,laboratory tests and colonoscopy. Multivariate Logistic regression analysis was applied to exam the potential influencing factors for colorectal polyps. Results : Eventually 880 residents were involved into the statistical analysis. Colorectal polyps were detected in 167 participants with a crude prevalence of 18.98% and adjusted prevalence for age and gender of 13.28%. The prevalence of colorectal polyps in men（28.70%）was significantly higher than that in women（12.92%,P<0.05）. The results of logistic regression analysis showed that age（OR=1.038,95%CI：1.018-1.057）,males（OR=1.919,95%CI：1.303-2.826）,the middle school level of education（OR=2.443,95%CI：1.507-3.961）and constitution of Yin-Asthenia（OR=0.203,95%CI：0.057-0.720）were influencing factors for colorectal polyps;among male participants,hypertension（OR=1.721,95%CI：1.018-2.908）was a risk factor for colorectal polyps;among female participants,age（OR=1.076,95%CI：1.042-1.111）,BMI（OR=1.099,95%CI：1.001-1.207）,the middle school level of education（OR= 3.507,95%CI：1.794-6.856）and constitution of Yin-Asthenia（OR=0.160,95%CI：0.033-0.770）were influencing factors for colorectal polyps. Conclusion Age,sex,education level and constitution of Yin-Asthenia were associated with the risk of colorectal polyps among residents in Lanxi;hypertension was associated with the risk of colorectal polyps in males,while age,BMI,education level and constitution of Yin-Asthenia were associated with the risk of colorectal polyps in females.

Objective To explore the expression and significance of serum DKK1 in patients with gastric cancer. Methods We selected 170 gastric cancer patients (gastric cancer group) and 170 subjects with non-gastric cancer during the same period (control group). ELISA was used to detect the DKK1 level. The ROC curve was used to evaluate the diagnostic performance, and we analyzed the relation between DKK1 level and age, gender, family history of gastric cancer, cigarette smoking, alcohol consumption, tumor size, TNM stage, infiltration depth, lymph node metastasis, liver metastasis, vascular invasion, perineural invasion. Results The serum DDK1 level in GC patients was higher than that in control group (P < 0.0001). ROC curve showed that the possible optimal cut-off value of DKK1 for gastric cancer patients was 167.8 pg/ml, AUC was 0.908, sensitivity was 80.59%, and specificity was 84.71%. There was no significant relation between the serum DKK1 level and age, gender, family history of gastric cancer, cigarette smoking, alcohol consumption, tumor size, liver metastasis, vascular invasion or distant metastasis (all P > 0.05). However, DKK1 level was significantly related with TNM stage, infiltration depth, lymph node metastasis and perineural invasion (all P < 0.05). Conclusion Serum DKK1 level is higher in gastric cancer patients than that of control group and related with the severity of lesions, which indicates that serum DKK1 may be a potential biomarker for gastric cancer screening.

Objective To screen the epithelial mesenchymal transformation(EMT)-related genes in lung adenocarcinoma,perform functional enrichment analysis and construct protein interaction network(PPI).Ac-cording to the competitive endogenous RNA(ceRNA)hypothesis and the effect of gene expression on the prognosis of patients,the ceRNA network was constructed.Methods The differentially expressed genes be-tween lung adenocarcinoma tissues and normal tissues were screened by gene expression map and tumor ge-nome map database,and the genes were imported into GenClip3 to obtain EMT-related genes.Metascape was used to perform gene ontology and Kyoto encyclopedia of gene and genome enrichment analysis,and STRING database was used to construct PPI and obtain EMT key genes.The relationship between key genes and prog-nosis was analyzed by Kaplan-Meier analysis.Analysis tools such as miRTarbase,miRNet database,and EN-CORI were used to construct ceRNA networks.Results In this study,156 lung adenocarcinoma EMT-related genes and their key genes cadherin 1,interleukin-6,matrix metalloproteinase-9,platelet endothelial cell adhe-sion molecule,cyclin-dependent kinase inhibitor 2A,α1-Ⅰcollagen gene,secreted phosphoprotein 1,TIMP in-hibitor of matrix metalloproteinase-1,caveolin-1 and Zeste homologue enhance core 2(EZH2)-1 were identi-fied.The PPI of key genes was predicted,and the therapeutic drugs targeting these key genes including salvia miltiorrhiza,ginseng lu,ginseng leaf and ginseng flower were also predicted.The prognostic ceRNA regulatory network of EZH2/hsa-miR-101-3p/GSEC was constructed.Conclusion This study describes using bioinfor-matics methods system in the process of EMT gene interactions,according to the lung adenocarcinoma pa-tients clinical data to construct the prognosis of the EMT process related ceRNA network,for the treatment and prognosis of lung adenocarcinoma judgment provides a new way of thinking.

Objective To overview the methodological quality,report quality and evidence quality of the Meta-Analyses/Systematic Reviews(MAs/SRs)of acupuncture for post-stroke cognitive impairment(PSCI).Methods A search was conducted for MAs/SRs on PSCI using English or Chinese from inception to 20 February 2022 published in four Chinese databases:CNKI,Wanfang,VIP,CBM;and three English databases:PubMed,Embase and Cochrane Library.The MAs/SRs were evaluated for methodological quality using AMSTAR 2 and for reporting quality using PRISMA,and the quality of evidence was assessed using the GRADE system.Results A total of 18 MAs/SRs were included in this study,of which 89%showed the effectiveness and safety of acupuncture for PSCI.According to AMSTAR 2,1 study was of low methodological quality and 17 studies were of critically low quality;according to PRISMA,1 study was of high quality,16 studies were of moderate quality and 1 study was of poor quality;GRADE showed that of the 71 outcomes included,however,there was no evidence of high quality outcomes,with 10 of moderate quality,17 of low quality,and 44 of very low quality.Conclusion Acupuncture may be effective and safe in the treatment of PSCI,but in current acupuncture for PSCI is generally of low quality and should be interpreted with caution.

Objective A scoping review of clinical research studies on acupuncture and moxibustion intervention in mild cognitive impairment(MCI),to get a comprehensive understanding of the current state of research in the field,in order to provide reference for the key research direction and clinical decision-making of acupuncture and moxibustion intervention in MCI in the future.Methods Systematic searches were carried out in Chinese and English databases(such as CNKI,Wanfang,VIP,China Biomedical Database,Pubmed,Web of Science,Embase,The Cochrane library),and trial registration platforms(such as WHO ICTRP and Clinical Trials.gov).the clinical studies and Systematic Reviews(SRs)and/or Meta-analyses(MAs)of acupuncture and moxibustion in the treatment of MCI were collected.The search language is limited to Chinese and English,and the search time is from the establishment to July 27,2022.The final included studies were summarized from the aspects of annual publication trend,the patterns of Traditional Chinese medicine(TCM)syndrome differentiation,acupuncture treatment plan,and outcome indicators of clinical studies.AMASTAR 2 was used to evaluate the methodological quality of SRs/MAs,and evidence mapping was constructed using bubble charts,etc.Results 108 original clinical studies and 9 SRs/MAs were included.The included clinical studies were randomized controlled trials.From 2006 to 2022,the number of publications generally showed an upward trend.Kidney essence deficiency syndrome was the most common dialectical classification in TCM.Special acupuncture treatment regimens are most common as interventions.And outcome measures were mainly Mini-Mental State Examination,Montreal Cognitive Assessment,and Activities of Daily Living,and so on.The assessment of AMSTAR 2 showed at least more than 2 critical flaws,the methodological quality of included SRs/MAs was critically low.Conclusion At present,acupuncture and moxibustion intervention for MCI has a good development prospect and is worthy of in-depth study,but there are still problems such as a single type of clinical study,lack of unified standards for TCM syndrome differentiation,and further standardization of outcome indicator reporting.In addition,the quality of existing evidence for SRs/MAs is generally low,and more in-depth studies are needed to clarify the clinical efficacy and safety of acupuncture and moxibustion intervention for MCI.

OBJECTIVE To comprehensively evaluate the three oral Janus kinase inhibitors （JAKi） such as upadacitinib， abrocitinib and baricitinib in the treatment of atopic dermatitis. METHODS The six dimensions of safety， efficacy， economy， appropriateness， accessibility and innovativeness were used for evaluation. Meta-analysis was conducted to evaluate the safety and efficacy of three oral JAKi； pharmacoeconomic studies were searched， and the treatment costs were calculated to evaluate the economy of each JAKi. Appropriateness was described based on literature review and drug labels. Accessibility of three oral JAKi was assessed by using a questionnaire survey. The innovation of JAKi was elucidated from the perspective of its mechanism of action. RESULTS In terms of safety， the incidence of upper respiratory tract infection （OR＝1.47， 95%CI of 1.04-2.08， P＝0.03） and nasopharyngitis （OR＝1.44， 95%CI of 1.06-1.95， P＝0.02） in the upadacitinib 30 mg group was significantly higher than that in the placebo group； the incidence of nasopharyngitis in baricitinib 4 mg group was significantly higher than that in the placebo group （OR＝2.24， 95%CI of 1.39-3.61， P＝0.000 8） and baricitinib 2 mg group （OR＝0.48， 95%CI of 0.31-0.74，P＝0.001）. In terms of efficacy， regardless of the dosage， all three JAKi groups were superior to the placebo group， and the high-dose groups of upadacitinib and abrocitinib were superior to the low-dose groups （P＜0.000 1）. In terms of economy， the annual treatment cost of baricitinib was the lowest （13 870.0 yuan）， but it has not been approved for atopic dermatitis indication in China； next was upadacitinib （27 192.5 yuan）. In terms of appropriateness， the overall appropriateness of the three JAKis was good， but none of them was suitable for patients with severe liver injury. In terms of accessibility， baricitinib had the highest availability rate （59.4%）， but the affordability of upadacitinib was relatively good under China’s medical insurance system. In terms of innovation， among the three types of JAKi， upadacitinib and abrocitinib had better innovation. CONCLUSIONS Three oral JAKi treatments for atopic dermatitis have controllable safety and good efficacy. Considering the issue of medical insurance reimbursement， it is recommended that Chinese patients use upadacitinib.
