Objective:To observe the clinical effect of acupuncture on chronic obstructive pulmonary disease (COPD), and the improvements of patients’ pulmonary ventilation function and 6-minute walk test (6-MWT) distance. Methods:A total of 80 COPD patients [grade 3-4 in Global Initiative for Chronic Obstructive Lung Disease (GOLD), qi deficiency of the lung and kidney in traditional Chinese medicine (TCM) pattern] were randomly allocated into a treatment group (n=40) and a control group (n=40). Salmeterol Xinafoate and Fluticasone Propionate powder (Seretide,50μg/250μg) for inhalation was used for basic treatment in both groups (once in the morning and once in the evening). Patients in the treatment group received acupuncture at Feishu (BL 13), Shenshu (BL 23), Qihai (CV 6), Guanyuan (CV 4), Dingchuan (EX-B 1), Danzhong (CV 17) and Zusanli (ST 36) twice a week for 3 months. After 3 months of treatment, clinical effects, lung ventilation functions and 6-MWT distance were observed and compared in the two groups. Results:After 3 months of treatment, the total effective rate was 95.0% in the treatment group, versus 80.0% in the control group, showing a statistical difference (P<0.05); the phlegm expectoration, dyspnea and shortness of breath were more significantly improved in the treatment group than those in the control group (P<0.01,P<0.05); and the 6-MWT distance and forced expiratory volume in 1 second percentage of predicted value (FEV1%) were more significantly improved in the treatment group than those in the control group (P<0.05,P<0.01). Conclusion:Seretide inhaler combined with acupuncture can improve signs and symptoms in COPD patients, increase the 6-MWT distance, improve FEV1% and obtain better results than Seretide alone.

By reverse transcription-polymerase chain reaction (RT-PCR), an open reading frame of pathogenesis-related protein 1 (PR1) was isolated from Panax notoginseng and named as PnPR1. Molecular and bioinformatic analyses of PnPR1 revealed that an open reading frame of 501 bp was predicted to encode a 166-amino acid protein with a deduced molecular mass of 18.1 kD. Homology analysis showed that the deduced amino acid sequence of PR1 protein of Panax notoginseng had a high similarity with other higher plants had the same conservative structure domain of cysteine-rich secretory protein (CAP). The recombinant expressed plasmid pET28a(+)-PnPR1 was expressed in Escherichia coli BL21. The expression conditions were optimized by induction at different times, different temperatures, different IPTG concentrations and different giving times. The optimum expression condition was 0.4 mmol.L-1 IPTG at 28 degrees C for 20 h. The successful expression of PnPR1 provides some basis for protein purification and preparation of the monoclonal antibody.

Objective To investigate SIAH′s role in α-synuclein degradation, formation of Lewy bodies and neuronal death. Methods Proliferative activity of PC12 cells was measures by MTT assay after treatment with MPP and Rapamycin. Western Blot was applied determine the protein expression of LC3-Ⅱ, E1, SIAH-1, P53 and α-synucleinto. PCR was applied to measure protein related mRNA levels. Immunofluorescent techniques were used to detect the distribution of α-synuclein, SIAH-1 and LC3 in cells after SIAH antibody processing. Results MPP+ treatment increased α-synuclein, E1 expression and SIAH-1 activity, however, LC3-Ⅱ, P53 and α-synuclein protein levels decreased significantly. Anti-SIAH-1 antibody treatment reversed this trend, with E1 significantly increased. Rapamycin treatment reduced SIAH-1 and α-synuclein levels in the MPP+ group. SIAH-1 antibody significantly decreased the positive immuno-stain of α-synuclein, SIAH-1 and LC3, suggesting loss of co-localization. Conclusions Anti-SIAH-1 supports the clearance of non-aggregated α-synuclein by the UPS. SIAH plays a key role in the pathogenesis of Parkinson′s disease and is a potential therapeutic target of neurodegenerative diseases.

Objective:To analyze Traditional Chinese Medicine(TCM) prescriptions in COVID-19 patients in Shanghai area.Methods:Two hundred and forty patients were enrolled in the study, including 19 mild cases, 199 moderate cases, 16 severe case and 6 critical cases. The COVID-19 formula in Shanghai area was extracted and input in TCM Inheritance platform. Data association method such as software association rules,improved mutual information method,complex system entropy clustering,unsupervised entropy hierarchical clustering were used to analyze the frequency,herb flavor and meridian, combination rule and core combination of different types of Chinese herbs in the treatment of COVID-19 in Shanghai area.Results:According to the frequency analysis of 240 prescriptions of Chinese medicine,194 herbs were found. The COVID-19 formula herbs were all "cold", the frequency of use in mild, moderate, severe and critical cases was [46.02%(104/226), 46.31%(1 230/2 656), 37.06%(146/394), 39.24%(31/79)]. The flavor was mainly "bitter" and the frequency of use in 4 types of disease were [36.53%(122/332), 37.33%(1 445/3 857), 35.96%(205/564), 33.62%(39/113)]. Scutellaria was the most frequently used TCM of "bitter and cold". The drugs used were mainly lung,stomach and spleen meridians. By comparing the formulas between mild and moderate cases,herb combinations with the highest frequency were all "scutellaria glycyrrhiza" and "tangerine glycyrrhiza". The formulas for 19 mild cases were collected,and 197 drug combinations were counted, and 125 Chinese medicine association rules,including 13 Chinese herbs. The formulas were extracted in 199 moderate cases of COVID-19, a total of 92 drug combinations and 38 Chinese medicine association rules were collected,including 19 Chinese herbs. In 16 severe cases, a total of 62 drug combination models and 46 Chinese medicine association rules were collected,including 17 Chinese herbs. For the 6 critical cases,80 Chinese medicine prescriptions were combined,and 10 Chinese medicine association rules, including 12 Chinese herbs.Conclusions:The herbal prescriptions of COVID-19 in Shanghai are characterized by clearing away heat and resolving dampness. By analyzing prescription rules with complex system entropy clustering, association compatibility ideas of different types of traditional Chinese medicine are found to be different among four types of COVID-19 cases. Analyzing the connection rules in formulas, by using the theory of TCM and pharmacology of traditional Chinese medical formula in different COVID-19 patients may be helpful for general practitioners.
