Analysis of prescription and medication rules of traditional Chinese medicine in the treatment of the coronavirus disease 2019 based on traditional Chinese medicine inheritance support platform / 中华危重病急救医学

Objective:To analyze the rules of medication and principles of formulas for the treatment of coronavirus disease 2019 (COVID-19) using the traditional Chinese medicine inheritance support platform (V2.5).Methods:The clinical data, including gender, age, clinical symptoms, frequency of traditional Chinese medicine medication and prescription information, of patients with COVID-19 and asymptomatic infection who were admitted to Hebei COVID-19 designated hospital supported by medical team of First Affiliated Hospital of Hebei University of Chinese Medicine from January to March 2021 were collected. The information data were input into the traditional Chinese medicine inheritance support platform (V2.5). The data mining and analysis were realized by the integrated association rules and complex entropy clustering analysis methods of the software, including the analysis of the frequency of each drug use, drug meridian, taste, and prescription rules, and the new prescriptions were developed.Results:A total of 564 patients (564 prescriptions) were enrolled, involving 200 Chinese herbs, including 357 cases of common COVID-19 and 207 cases of asymptomatic infection. The proportion of women with common COVID-19 was high, and the high incidence age group was 51-70 years old. There was no significant difference in gender of asymptomatic infection, and the high incidence age group was 1-20 years old. The main clinical manifestations of most patients were head heavy and cough, followed by low fever and cough with sputum, the main tongue coating and pulse pattern were similar in both types of patients. The frequency of traditional Chinese medicine used in patients with common type of COVID-19 from high to low was liquorice root (326 times), indian bread (264 times), pinellia tuber (263 times), bitter apricot seed (236 times), baical skullcap root (229 times), gypsum (205 times), agastache rugosus (201 times), dried tangerine peel (194 times), ephedra (184 times), and Chinese thorowax root (163 times), while that used by asymptomatic infection were baical skullcap root (174 times), liquorice root (142 times), medicated leaven (137 times), agastache rugosus (127 times), pinellia tuber (114 times), Chinese thorowax root (100 times), officinal magnolia bark (91 times), atractylodes rhizome (89 times), peony root (84 times), and milkvetch root (83 times). The two types of patients were mainly treated with warm, cold and flat drugs, and the nature and taste were mainly pungent, bitter and sweet. The meridian tropism of drugs was mainly lung, spleen and stomach. High frequency drug formulation mainly included drugs for resolving turbidity and detoxification. At the same time, seven new prescriptions for common COVID-19 and four new prescriptions for asymptomatic infection were developed.Conclusions:The primary reason for the COVID-19 occurrence and development is turbidity-toxin and the qi of plague, and resolving turbidity and detoxication are the basic treating principle. On the basis, for patients with common COVID-19, symptomatic treatment such as relieving exterior syndrome, clearing heat, resolving phlegm, and antitussive drugs should be taken into account at the same time, while the treatment of asymptomatic infections should focus more on supporting the body and eliminating the harmful pathogens.

Objective To investigate the clinical effectiveness and safety of acupuncture at Zusanli (ST36),Taichong(LR3) and Hegu(LI4) points combined with three-step analgesic ladder for the treatment of gastric cancer pain.Methods Sixty patients with moderate and severe pain induced by gastric cancer were randomly divided into study group and control group,30 cases in each group.The study group was treated with acupuncture at Zusanli,Taichong and Hegu points combined with three-step analgesic ladder for gastric cancer pain management,and the control group was treated with three-step analgesic ladder only.After treatment for 7 days,the clinical effectiveness was evaluated with the average pain scores of Numerical Rating Scale(NRS),Quality of Life Scale(QOL-BREF by WHO),Self-rating Depression Scale(SDS).And the incidence of adverse reaction was also observed.Results (1) After treatment,the markedly-effective analgesic rate of the study group was higher than that of the control group (P ＜ 0.05).(2) After treatment,QOL scores of both groups were much improved as compared with those before treatment(P ＜ 0.05),and the improvement of the study group was superior to that of the control group(P ＜0.05).(3) The depression scores of both groups were much improved after treatment (P ＜ 0.05 compared with those before treatment),but the difference between the two groups was insignificant(P ＞ 0.05).(4) The incidence of adverse reaction of the study group was lower than that of the control group(P ＜ 0.05).Conclusion The effect of acupuncture at Zusanli,Taichong and Hegu points combined with three-step analgesic ladder is better than three step analgesic ladder alone for the treatment of gastric cancer pain.

Durability of protective effect of resin-based coating material on root surface / 北京大学学报(医学版)

Objective:To compare the durability of resin-based root-surface coating material and all-in-one self-etching adhesive on root surface in vitro.Methods:Human extracted premolars or molars with intact roots were selected.The cementum was removed using a periodontal scaler to expose root dentin. The root surface was coated with an acid-resistant nail varnish,leaving a window of 3 mm ×3 mm on the exposed dentin.The window was covered with either PRG Barrier Coat (PRG)or Clearfil S3 Bond (CS3).After water aging for 14 d,specimens were immersed in acid buffer at pH 4.5 for 4 d and the demineralization buffer was changed every 24 h.Then the specimen was split longitudinally through the center of the ‘window’and the cross-sectional surface was observed with scanning electron microscope (SEM).After fixed and dehydrated,the prepared samples were coated with platinum.The coating mate-rial,root dentin and the interface was observed by scanning electron microscope (SEM).The thickness of the coating material was measured on the SEMimages.Regarding toothbrush wear test,coronal dentin-disks were prepared and covered with PRG and CS3,respectively.After storage in water for 24 h,the specimen was subjected to the toothbrush wear tester for 100,200,300,500,700,1 500 brushing cy-cles.A slurry of fluoride toothpaste (1 ∶2 ratio of toothpaste and deionized water by weight)was used and the brushing load was 300 N.The surface microstructure of remaining coating material was analyzed using SEM.The wear depths were determined by a profilometer.Statistical analysis was performed with SPSS 20.0 by one-way ANOVA.The level of significance was at 0.05.Results:Application of PRG Barrier Coat produced a coating layer of (47.1 ±27.3)μm,while CS3 presented a thin film of (5.7 ± 2.1)μm in thickness.The exposed dentin was hermetically sealed and no obvious gap was observed at the interface in both PRG and CS3 groups.There was no dentin demineralization observed in both groups after water aging.The wear depths of PRG and CS3 increased along with the numbers of brushing cycles. PRG wore at a significant lower pace than CS3 did (P <0.05).Conclusion:PRG coating resin had similar performances as CS3 on protecting root dentin from demineralization after water aging.What’s more,PRG demonstrated a higher toothbrush wear resistance than CS3.We concluded that PRG Barrier Coat contained S-PRG filler may be an effective coating material for protecting exposed root from both chemical and mechanical challenges.Further studies should be carried out to evaluate the long-term reli-ability of the rootsurface coating materials under the clinical setting.

Effects of Huoxue Huayu and Yiqi Wenyang compound prescription of TCM on congestive heart failure in rats / 中国病理生理杂志

AIM: To study the effects of Huoxue Huayu and Yiqi Wenyang compound prescription (composition; ginseng, radix astragali, plantaginis semen, lignum sappan, chuanxiong, salvia miltiorrhiza, radix aconiti lateralis preparata, bitter orange, cassia twig) of TCM on the congestive heart failure in rats. METHODS:The rats were given doxorubicin hydrochloride by intraperitoneal injection to establish the model of congestive heart failure and were randomly divided into control group, congestive heart failure model group, Xinbao treatment group ( XB treatment) and Huoxue Huayu and Yiqi Wenyang compound prescription treatment group (QXYTM treatment). Normal saline, liquid medicine Xinbao and liquid medicine Huoxue Huayu and Yiqi Wenyang compound prescription were administered respectively to four groups by gavage. Radioimmunoassay, semi - quantitative RT - PCR and flow cytometry methods were used to determine the expressions of plasma atrial natriuretic peptide ( ANP) , renal medulla aquaporin - 2 ( AQP2 ) and heat shock protein70 (HSP70) in congestive heart failure rats before and after treatment. RESULTS: In congestive heart failure rats treated with Huoxue Huayu and Yiqi Wenyang compound prescription, the cardiac output and left ventricle systolic pressure increased significantly, the left ventricular end diastolic pressure decreased, and the maximum ascending and declining rate of left ventricular pressure ameliorated, thus the hemodynamics was effectively improved. Meanwhile, the level of plasma cardionatrin decreased, the abnormal expression of renal medulla AQP2 was markedly restored, and the transcription and expression of HSP70 gene were also increased. CONCLUSION: Huoxue Huayu and Yiqi Wenyang compound prescription promotes the recovery of the pathogenetic conditions of congestive heart failure in rare. The mechanism may be in association with a decrease in plasma ANP level, correction of renal medulla AQP2 abnormal expression and enhancement of HSP70 expression.
