ABSTRACT
ObjectiveTo evaluate the methodological quality of traditional Chinese medicine （TCM） diagnosis and treatment guidelines/consensus of constipation with Appraisal of Guidelines for Research and Evaluation Ⅱ （AGREE Ⅱ）tool， and to study the attention situation of the included Chinese patent medicines in China's National Reimbursement Drug List in the guidelines/consensus. MethodThe data of CNKI，VIP，Wanfang Data，SinoMed，PubMed and Cochrane from the inception of the databases to October 2021 were searched to collect the TCM diagnosis and treatment guidelines/consensus of constipation. Then，the diagnosis and treatment standards and recommended Chinese patent medicines were extracted. Two researchers assessed the methodological quality of the guidelines/consensus with AGREE Ⅱ tool independently. The quality of reports was evaluated by Reporting Items for practice Guidelines in HealThcare （RIGHT） Statement. The recommended Chinese patent medicines in the guidelines/consensus were compared with those in the National Reimbursement Drug List. ResultEleven consensus and 2 guidelines were included，involving 794 experts. The scores of AGREE II were clarity of presentation（59.0%），scope and purpose（44.0%），stakeholder involvement（23.1%），rigor of development （12.1%），applicability （11.1%），and editorial independence （8.3%） from high to low. Five articles were recommended at B level（recommended after revision） and 8 articles were at C level （not recommended）. The average scores of RIGHT Statement were as follows：basic information （93.59%），background （57.69%），evidence （18.46%），recommendations （20.88%），review and quality assurance （19.23%），funding，declaration and management of interests （0.00%）， and other information （0.00%）. The included guidelines/consensus recommended a total of 27 Chinese patent medicines，among which 20 were included in the National Reimbursement Drug List，with 4 species of Class A and 16 species of Class B， accounting for 74.1% of all recommended Chinese patent medicines. Ten purgative Chinese patent medicines in the National Reimbursement Drug List were recommended by the guidelines/consensus，accounting for 50% of all purgative drugs， and 8 were not recommended. There were prescriptions for purgation， for promoting digestion and removing food stagnation， for clearing heat and purging fire，and for warming the middle and dissipating cold，Tibetan medicine and Mongolian medicine. ConclusionBy the AGREE Ⅱ assessment，the methodological quality of the TCM diagnosis and treatment guidelines/consensus of constipation included in this study needed to be improved in the future. The report quality evaluated with RIGHT Statement was low. Most drugs included in the National Reimbursement Drug List were paid attention in the TCM diagnosis and treatment guidelines/consensus of constipation. Moreover，the drugs included in the National Reimbursement Drug List could basically fulfill the clinical needs reflexed from the guidelines/consensus recommendations. However， the reasons of some drugs failing to be included in the National Reimbursement Drug List needed to be studied in the future.
ABSTRACT
Objective:To investigate high mobility group protein 1(HMGB1), tumor necrosis factor-α(TNF-α)and interleukin-6(IL-6)levels and their clinical significance in elderly patients with viral pneumonia.Methods:One hundred and sixty elderly patients with viral pneumonia admitted to the Sixth Hospital Affiliated to Anhui Medical University were enrolled as research subjects.In addition, 40 elderly people who underwent regular physical examination were considered as the control group.Patients with viral pneumonia were divided into the low-risk group, middle-risk group and high-risk group according to CURB-65 scores and pneumonia severity index(PSI)scores.HMGB1, TNF-α and IL-6 levels were compared between different groups.The correlations of CURB-65 scores and PSI scores with HMGB1, TNF-α, IL-6 levels were analyzed.Multivariate Logistic regression analysis was used to examine influencing factors for the severity of viral pneumonia in elderly patients.Results:HMGB1, TNF-α and IL-6 levels were higher in research subjects than in the control group.As the severity of viral pneumonia increased, so did HMGB1, TNF-α and IL-6 levels(all P<0.05). HMGB1, TNF-α and IL-6 levels in the severe viral pneumonia group were significantly higher than those in the non-severe viral pneumonia group( P<0.05). HMGB1, TNF-α and IL-6 levels were positively correlated with CURB-65 scores and PSI scores(CURB-65 score: r=0.463, 0.392 and 0.497, P=0.015, 0.003 and 0.025; PSI score: r=0.596, 0.515 and 0.381, P=0.007, 0.011 and 0.009). HMGB1, TNF-α and IL-6 levels were influencing factors for the severity of viral pneumonia in elderly patients( OR=1.344, 1.422 and 1.351, P=0.006, 0.015 and 0.009). Conclusions:HMGB1, TNF-α and IL-6 levels are closely correlated with the severity of viral pneumonia and are helpful for early assessment of viral pneumonia.
ABSTRACT
Objective To verify the interaction between asialoglycoprotein receptor (ASGPR)and hepatitis B virus (HBV)preS1 protein in vivo and in vitro ,and identify ASGPR as a cell-surface receptor for HBV,which could elucidate the molecular mechanism of HBV infection.Methods The preS1-ASGPR interaction was examined in mammalian two-hybrid and coimmunoprecipitation system by strictly following the manufacturer’s instructions.Results ASGPR interacted specifically and directly with the preS1 domain of HBV in vivo and in vitro .Conclusion ASGPR may be a candidate receptor for HBV that mediates further step of HBV entry.
ABSTRACT
OBJECTIVE:To study the preventive effect of emodin and astragalus polysaccharides on experimental hepato-carcinoma in rats.METHODS:The experimental rats were randomly divided into the normal group,model group,emodin group,and emodin combined with astragalus polysaccharides group.hepatocarcinogenesis in rat models were induced by di-ethylnitrosamine,while at the same time all the groups were administered with pre-set drugs by stomach irrigation.Rat's we_ ight,serum indices of ALT,ALP,?-GT,?-L-fucoxidase were determined,and pathological examination was made before and after administration.RESULTS:The group administered with emodin and astragalus polysaccharides improved more than any other groups in terms of rat's weight,serum indices,onset time of hepatocarcinogenesis,and pathological grade.CONCLU_ SION:Emodin combined with astragalus polysaccharides have certain preventive effect on experimental hepatocarcinoma in rats.
