ObjectiveTo develop the Evidence Grading Scale for Ancient classical prescriptions in Traditional Chinese medicine， assess its reliability and validity， and apply it in practice to provide multi-source evidence for clinical practice guidelines development. MethodsLiterature retrieval was conducted to extract and screen existing evaluation dimensions， then the initial items were summarized using thematic analysis. Experts in the clinical medicine， medical history and literature participated in the Delphi questionnaire survey to evaluate and refine the items. An expert consensus meeting was conducted to finalize the included items， refine the method for items evaluation and evidence grading. The evidence quality rating scale for ancient classical traditional Chinese medicine （TCM） prescriptions was then established and tested for reliability and validity. ResultsThrough literature review， extraction， screening and summarization， a total of 3 dimensions and 12 initial items were formed. Questionnaires were sent to 69 experts to evaluate the initial items， with a questionnaire response rate of 100% and an expert authority coefficient of 0.92. All 12 items were retained for they had importance scores above 4. The Evidence Grading Scale on Ancient classical prescriptions in Traditional Chinese medicine includes 3 dimensions with 12 items. The 3 dimensions includes ancient evidence， inheritance status， and modern application. Each dimension contains 4 items， and each item has a full score of 5 points. The evidence was rated as high-level， moderate-level， and low-level according to the final scores. The content validity index （CVI） of the 12 items was ＞0.9， the average CVI of the scale was 0.98， and the intraclass correlation coefficient （ICC） was 0.90. ConclusionThe Evidence Grading Scale on Ancient classical prescriptions in Traditional Chinese medicine has good reliability and validity， which is practical for use in the development of TCM clinical guidelines and can better support clinical decision-making.

Objective To analyze and identify the volatile constituents in different parts(flowers,stems and leaves)of Huai chrysanthemumin,and to lay a theoretical foundation for the comprehensive utilization for it.Methods The volatile oil in different parts of Huai chrysanthemumin were extracted by hydrodistillation,respectively.Their constituents were analyzed by gas chromatography-mass spectrometry(GC-MS).The compounds were identified by library search and literature screening.The relative percentage of each compound was obtained by the area normalization method.The differences in their chemical compositions were analyzed by Venn diagram,principal component analysis(PCA)and cluster heat map analysis.Results A total of 62 volatile chemical components were identified from different parts of Huai chrysanthemumin,including monoterpenes,sesquiterpenes,and their derivatives,as well as a small amount of aliphatic compounds.32,42 and 40 volatile components were detected from the flowers,stems and flowers,respectively.Furthermore 17 volatile components were shared by three parts,whereas 5,6 and 16 volatile components were unique to the flowers,stems and leaves,respectively.The results of stoichiometric analysis showed that both PCA and cluster heat map analysis could separate the flowers,stems and leaves,and their volatile components were different.Conclusion The types and contents of the volatile oil in the stems,leaves and flowers of Huai chrysanthemumin have certain variability,which provide a scientific basis for the further medicinal or industrial exploitation of different parts of Huai chrysanthemumin.

Rheumatoid arthritis(RA)is a chronic and progressive autoimmune disease.Current clinical treatments for RA often exhibit inadequate drug responses and severe adverse effects,underscoring the necessity for alternative therapies.Baicalin,a flavonoid derived from Scutellaria baicalensis roots,possesses anti-inflammatory,antioxidant,and immunomodulatory properties.Research suggests that baicalin can inhibit the release of inflamma-tory mediators,thereby reducing inflammation.Moreover,it demonstrates antioxidant effects by decreasing reactive oxygen species production and mitigating synovial damage induced by oxidative stress.Baicalin may impede the activation of inflammatory cytokines through pathways such as NF-κB,MAPKs,and JAK-STAT signaling cascades while inducing apoptosis,regulating immune cell activity,and balancing immune mediators to impact synovitis progression.Clinically,both monotherapy with baicalin or its combination with other formulations have exhibited efficacy and safety profiles.The advancement in targeted drug delivery systems has improved its bioavailability further suggesting promising clinical applications.This review provides an overview of research progress on baicalin's mechanisms in inhibiting RA synovitis along with its clinical applications.

Objective To establish methods for detection of water in rubber closures as one of the Chinese Pharmacopoeia series of standards for pharmaceutical packaging material.Methods The formulation process of determination of water in rubber closures was explained,the key contents of the standard were analyzed,and the determination results of water content by oven-drying method and Karl Fischer drying furnace-coulometric titration method were compared.Results The determination results of water content in multiple batches of rubber stopper samples by over-drying method were generally higher than that by Karl Fischer drying oven-Coulometric titration method.The latter method is highly specific and accurate,and can better reflect the true water content of rubber closures.Conclusion Two methods for determining water content in rubber closures have been developed.Enterprises can choose the appropriate method based on the intended use of their products and daily testing needs.

Objective To investigate the association between baseline normal neutrophil/lymphocyte ratio(NLR)changes and the risk of diabetic peripheral neuropathy(DPN).Methods A total of 200 type 2 diabetes mellitus(T2DM)patients admitted to our hospital from November 2016 to November 2021 were retrospectively selected.They were divided into DPN group(87 cases)and T2DM group(113 cases)according to whether peripheral neuropathy was present.In the verification group,there were 26 T2DM patients combined with DPN.Multivariate Cox regression analysis was used to analyze the risk factors affecting DPN.A homogram prediction model was constructed.Receiver operating characteristic(ROC)curve and calibration curve were used to evaluate the predictive efficiency of the model.All patients were followed up for 1 year to compare the effects of changes in NLR on the risk of new DPN and nerve conduction velocity.Results DM duration(HR 2.358,95%CI 1.754～3.658),triglyceride(HR 3.085,95%CI 2.454～6.778),baseline NLR(HR 3.145,95%CI 1.466～5.632)were risk factors for DPN.The model of line graph has good distinction and accuracy.Elevated NLR(HR 3.258,95%CI 1.678～4.694)and high baseline NLR(HR 2.365,95%CI 1.547～4.526)were independent risk factors for new DPN after 1 year in the DPN-free group(P<0.05).There is a significant negative correlation between NLR and nerve conduction velocity in patients with T2DM(P<0.05).Conclusions Within the baseline normal range,the higher the NLR ratio,the greater the risk of DPN and the slower nerve conduction velocity,which is not conducive to the prognosis of patients.

Objective:To evaluate and compare efficacy of intravenous immunoglobulin (IVIG) versus recombinant human tumor necrosis factor-α receptor Ⅱ:IgG Fc fusion protein (rhTNFR:Fc) in the treatment of toxic epidermal necrolysis (TEN) .Methods:Clinical data were collected from patients with TEN treated with IVIG or rhTNFR:Fc in Wuhan No.1 Hospital from 2013 to 2019. There were 11 patients in the IVIG group, including 3 males and 8 females, aged 25-72 years, and the median TEN-specific severity-of-illness score (SCORTEN) was 3 points; there were 10 patients in the rhTNFR:Fc group, including 5 males and 5 females, aged 32-84 years, and the median SCORTEN was 2 points. These patients all showed no response to the 5-day treatment with prednisolone acetate at a dose of 0.6-1.0 mg·kg -1·d -1, and then received IVIG at a dose of 400 mg·kg -1·d -1 for 5 consecutive days, or subcutaneous injection of rhTNFR:Fc at a dose of 25 mg every other day for 4-6 sessions. Changes in skin lesions and adverse events were recorded in the 2 groups. Statistical analysis was carried out by using Mann-Whitney U test. Results:Compared with the rhTNFR:Fc group, the IVIG group showed a significant decrease in the time to onset of reduction of skin lesion exudate (1.73 ± 1.19 days vs. 3.00 ± 1.56 days, P < 0.05) , time to onset of pain relief in the lesion area (1.64 ± 1.28 days vs. 3.70 ± 1.63 days, P < 0.05) , time to lightening of color of the lesion base (2.45 ± 1.12 days vs. 3.90 ± 1.59 days, P < 0.05) , time to onset of new epidermis growth (3.09 ± 1.13 days vs. 5.20 ± 1.22 days, P < 0.05) , and in the time to onset of lesion drying at the intertriginous sites (4.82 ± 2.22 days vs. 7.90 ± 3.14 days, P < 0.05) . However, there was no significant difference in the length of hospital stay between the IVIG group (17.70 ± 8.33 days) and rhTNFR:Fc group (16.70 ± 4.71 days, P > 0.05) . No adverse reactions were observed during the treatment, and no recurrence or complications were found in the 21 patients during the follow-up of 6 months. Conclusion:IVIG and rhTNFR:Fc are both effective in the treatment of TEN, but IVIG is superior to rhTNFR:Fc in terms of the time to onset of pain relief, skin lesion exudate reduction and epidermal growth.

Objective:To evaluate the clinical efficacy of the Chinese herbal medicine compound Kangliu Pill combined with conventional Western medicine therapy in the treatment of patients with malignant glioma after surgery.Methods:A total of 100 patients with malignant glioma (grade Ⅲ-Ⅳ), who met the inclusion criteria and underwent surgery from January 2017 to November 2019, were divided into the treatment group of 48 patients and the control group of 52, according to the treatment method. The control group was treated with conventional surgery plus radiotherapy, and the treatment group was treated with Kangliu Pill on the basis of the control group. The patients were followed up for 1 to 2 years, and the survival rate, progression-free survival and median survival were recorded. The Karnofsky functional status score (KPS) and quality of life score (QOL) were used to evaluate the patients' survival and quality of life, and the adverse reactions during the treatment period were observed.Results:After treatment, the 1-year survival rates [97.92% (47/48) vs. 80.77% (42/52); χ2=5.847, P=0.016] and 2-year survival rates [89.47% (33/48) vs. 42.31% (22/52); χ2=7.051, P=0.008] in the treatment group were significantly higher than those in the control group. After treatment, the progression-free survival [(23.94±13.12) months vs. (15.82±8.65) months; t=3.63, P<0.01] in the treatment group was significantly higher than that of the control group. After treatment, the survival analysis using the life table method yielded a median survival of 21.13 months in the treatment group and 12.00 months in the control group, with statistically significant differences in median survival and cumulative survival rates between two groups ( P=0.001). The KPS and QOL scores in the treatment group were higher than those in the control group, but the differences between the groups were not statistically significant ( P>0.05). There was no serious adverse events occurred during the treatment period in both groups. Conclusion:Adjuvant therapy with Kangliu Pill can improve survival rate, prolong progression-free survival, median survival, improve quality of life, and enhance the efficacy of patients with malignant glioma after surgery.
