ObjectiveTo explore the effect of Ganshuang granule on liver fibrosis （S1 and S2） in chronic hepatitis B （CHB） with liver depression spleen deficiency and blood stasis syndrome. MethodA total of 100 patients were classified into the control group （50 in total with 4 lost and 2 rejected， 44 finally included） and observation group （50 in total with 5 lost and 2 rejected， 43 finally included） with the random number table method. Both groups were given oral entecavir tablets （0.5 mg/time， once a day， 12 months）， and oral glutathione tablets was applied depending on the conditions of patients. In addition， the control group took the analog drug of Ganshuang granule （3 g/time， 3 times/day， 12 months） and the observation group received Ganshuang granules （3 g/time， 3 times/day， 12 months）， followed by histological examination of the liver by puncture biopsy. The two groups were compared in terms of inflammatory activity grade and fibrosis stage， as well as liver stiffness measure （LSM）， liver function， hepatitis B virus （HBV） DNA， liver depression and spleen deficiency syndrome score， aspartate aminotransferase （AST）-to-platelet ratio index （APRI）， and fibrosis index based on the four factors （FIB-4）. ResultAfter treatment， liver fibrosis in the observation group was milder than that in the control group （P<0.05） and the inflammatory activity grade in the observation group was lower than that in the control group （P<0.05）. The effective rate in down-regulating inflammatory activity grade in the observation group was 77.78% as compared with the 45.83% in the control group （χ2=5.546， P<0.05）. The effective rate in decreasing the fibrosis stage in the observation group was 59.26%， which was higher than that （16.67%） in the control group （χ2=9.669， P<0.01）. The LSM and score of the liver stagnation and spleen deficiency syndrome in the observation group were lower than those in the control group at the 6th months and 12th months of treatment （P<0.05，P<0.01）. The levels of alanine aminotransferase （ALT）， AST， and alkaline phosphatase （ALP） in the observation group were lower than those in the control group （P<0.01）. The APRI and FIB-4 in the observation group were lower than those in the control group （P<0.01）. ConclusionThe Ganshuang granule combined with entecavir can alleviate inflammation and liver fibrosis， delay and reverse liver fibrosis， protect liver， and improve the traditional Chinese medicine syndrome of liver fibrosis （S1 and S2） in CHB， which is worth of clinical use and further research.

Effects of Tanreqing Capsule on the negative conversion time of nucleic acid in patients with COVID-19: A retrospective cohort study / 中西医结合学报

OBJECTIVE@#Traditional Chinese medicine plays a significant role in the treatment of the pandemic of coronavirus disease 2019 (COVID-19). Tanreqing Capsule (TRQC) was used in the treatment of COVID-19 patients in the Shanghai Public Health Clinical Center. This study aimed to investigate the clinical efficacy of TRQC in the treatment of COVID-19.@*METHODS@#A retrospective cohort study was conducted on 82 patients who had laboratory-confirmed mild and moderate COVID-19; patients were treated with TRQC in one designated hospital. The treatment and control groups consisted of 25 and 57 cases, respectively. The treatment group was given TRQC orally three times a day, three pills each time, in addition to conventional Western medicine treatments which were also administered to the control group. The clinical efficacy indicators, such as the negative conversion time of pharyngeal swab nucleic acid, the negative conversion time of fecal nucleic acid, the duration of negative conversion of pharyngeal-fecal nucleic acid, and the improvement in the level of immune indicators such as T-cell subsets (CD3, CD4 and CD45) were monitored.@*RESULTS@#COVID-19 patients in the treatment group, compared to the control group, had a shorter negative conversion time of fecal nucleic acid (4 vs. 9 days, P = 0.047) and a shorter interval of negative conversion of pharyngeal-fecal nucleic acid (0 vs. 2 days, P = 0.042). The level of CD3@*CONCLUSION@#Significant reductions in the negative conversion time of fecal nucleic acid and the duration of negative conversion of pharyngeal-fecal nucleic acid were identified in the treatment group as compared to the control group, illustrating the potential therapeutic benefits of using TRQC as a complement to conventional medicine in patients with mild and moderate COVID-19.

Early therapeutic interventions of traditional Chinese medicine in COVID-19 patients: A retrospective cohort study / 中西医结合学报

OBJECTIVE@#To observe the early interventions of traditional Chinese Medicine (TCM) on the conversion time of nucleic acid in patients with coronavirus disease 2019 (COVID-19), and find possible underlying mechanisms of action.@*METHODS@#A retrospective cohort study was conducted on 300 confirmed COVID-19 patients who were treated with TCM, at a designated hospital in China. The patients were categorized into three groups: TCM1, TCM2 and TCM3, who respectively received TCM interventions within 7, 8-14, and greater than 15 days of hospitalization. Different indicators such as the conversion time of pharyngeal swab nucleic acid, the conversion time of fecal nucleic acid, length of hospital stay, and inflammatory markers (leukocyte count, and lymphocyte count and percentage) were analyzed to observe the impact of early TCM interventions on these groups.@*RESULTS@#The median conversion times of pharyngeal swab nucleic acid in the three groups were 5.5, 7 and 16 d (P < 0.001), with TCM1 and TCM2 being statistically different from TCM3 (P < 0.01). TCM1 (P < 0.05) and TCM3 (P < 0.01) were statistically different from TCM2. The median conversion times of fecal nucleic acid in the three groups were 7, 9 and 17 d (P < 0.001). Conversion times of fecal nucleic acid in TCM1 were statistically different from TCM3 and TCM2 (P < 0.01). The median lengths of hospital stay in the three groups were 13, 16 and 21 d (P < 0.001). TCM1 and TCM2 were statistically different from TCM3 (P < 0.01); TCM1 and TCM3 were statistically different from TCM2 (P < 0.01). Both leucocyte and lymphocyte counts increased gradually with an increase in the length of hospital stay in TCM1 group patients, with a statistically significant difference observed at each time point in the group (P < 0.001). Statistically significant differences in lymphocyte count and percentage in TCM2 (P < 0.001), and in leucocyte count (P = 0.043) and lymphocyte count (P = 0.038) in TCM3 were observed. The comparison among the three groups showed a statistically significant difference in lymphocyte percentage on the third day of admission (P = 0.044).@*CONCLUSION@#In this study, it was observed that in COVID-19 patients treated with a combination of Chinese and Western medicines, TCM intervention earlier in the hospital stay correlated with faster conversion time of pharyngeal swab and fecal nucleic acid, as well as shorter length of hospital stay, thus helping promote faster recovery of the patient. The underlying mechanism of action may be related to improving inflammation in patients with COVID-19.

Research progress on chemical constituents and quality control of Tripterygium wilfordii preparations / 中国中药杂志

Tripterygium wilfordii preparations,with various biological activities such as immunosuppressive,anti-inflammatory and anti-cancer effects,are widely used in the treatment of autoimmune diseases such as rheumatoid arthritis,lupus erythematosus,and nephrotic syndrome. They have definite therapeutic effect,but often cause serious adverse reactions and result in damages to liver,kidney,blood,reproduction,and other systems due to their complex compositions,great toxicity,and narrow margin between the toxic and therapeutic dosages. At present,T. wilfordii preparations produced by different manufacturers exhibit large variations in clinical efficacy and side effects in account of their different chemical compositions and quality fluctuation due to differences in raw materials and production process. However,the existing quality standards are controversial in terms of index components and content limit,which cannot be effectively used for the overall quality control of the preparations. In this paper,the research progress on chemical constituents,quality standard and quality control methods of four T. wilfordii preparations including Tripterygium Tablets,Tripterygium Zongtie Tablets,Tripterygium Shuangceng Tablets and Tripterygium Glycosides Tablets was reviewed,in order to provide ideas and reference for the quality improvement of this type of preparations.

Advances on molecular mechanisms of Rehmannia glutinosa consecutive monoculture problem formation in multi-omics era / 中国中药杂志

Although consecutive monoculture problems have been studied for many years, no effective treatments are currently available. The complexity of systems triggered the formation of consecutive monoculture problems was one major cause. This paper elaborated the physiological and ecological mechanisms of consecutive monoculture problem formation based on the interaction relationship among multiple factors presented in the rhizosphere soil of consecutive monoculture plants. At same time, in this paper the multiple interactions among cultivated medicinal plants, autotoxic allelochemicals and rhizosphere microbial were proposed to be most important causes that derived the formation of consecutive monoculture problem. The paper also highlighted the advantage of 'omics' technologies integrating plant functional genomics and metabolomics as well as microbial macro-omics in understanding the multiple factor interaction under a particular ecological environment. Additionally, taking R. glutinosa as an example, the paper reviewed the molecular mechanism for the formation of R. glutinosa consecutive monoculture problem from the perspective of the accumulation of allelopathic autotoxins, the rhizosphere microecology catastrophe and theresponding of consecutive monoculture plants. Simultaneously, the roles of mutilple 'omics' technologies in comprehending these formation mechanism were described in detail. This paper provides finally a new insight to solve systematically the mechanism of consecutive monoculture problem formation on molecular level.

Acupuncture and drug for subcortical ischemic vascular disease complicated with depression: a randomized controlled trial / 中国针灸

<p><b>OBJECTIVE</b>To explore the difference in the efficacy and effect mechanism of subcortical ischemic vascular disease (SIVD) complicated with depression between acupuncture and medication.</p><p><b>METHODS</b>Sixty patients were randomized-into an acupuncture group and a medication group, 30 cases in each one. In the acupuncture group, acupuncture was applied to Baihui (GV 20), Shuigou (GV 26), Fengfu (GV 16), Fengchi (GB 20) and the others, once a day, 6 times a week. The treatment of 4 weeks made one session and totally 2 sessions were required. In the medication group, nimodipine 30 mg, three times a day and fluoxetine 20 mg, once a day were prescribed for oral administration, for 8 weeks totally. Before treatment, at the end of the 4th week and at the end of the 8th week of treatment, cerebral blood flow velocity (CBFV) and solubility CD40 ligand (sCD40L) were determined respectively. The scores in Montreal cognitive assessment (MoCA) and Hamilton' s depression scale (HAMD) were evaluated in the two groups. The efficacies on cognitive function and depression symptoms were compared in the patients between the two groups. Results Compared with the outcome before treatment, mean blood flow velocity (Vm) of middle cerebral artery (MCA), anterior cerebral artery (ACA) and posterior cerebral artery (PCA) was increased significantly at the end of the 4th week of treatment in the two groups (all P<0.05). At the end of the 8th week, Vm was increased much significantly (all P<0.01). The differences were not significant in comparison between the two groups (all P>0.05). Compared with the expression before treatment, sCD40L was reduced significantly after treatment in the patients of the two groups (all P<0.01), but the differ- ence was not significant between the two groups (all P>0.05). Compared with that before treatment, MoCA score was increased significantly after treatment in the two groups (all P<0.01), HAMD score was reduced sig- nificantly (all P<0.01), the differences were not significant in comparison between the two groups (all P>0.05). The total effective rate of cognitive improvement was 86.7% (26/30) in the acupuncture group and was 80.0% (24/30) in the medication group, the differences were not significant in comparison of the two groups (P>0.05). The total effective rate of the improvement in depression was 93.3% (21/30) in the acupuncture group and was 86.7% (26/30) in the medication group, the differences were not significant in comparison of the two groups (P>0.05).</p><p><b>CONCLUSION</b>Acupuncture could significantly increases CBFV and reduces serum sCD40L expressions in the patients of SIVD complicated with depression, and significantly improves cognitive function and relieves depression symptoms. The efficacy of it is similar to that of western medication. The increase of serum sCD40L expression is possibly involved in the occurrence and development of SIVD. Reducing sCD40L expression contributes to the alleviation of damage induced by cerebral ischemia and reperfusion.</p>

A novel antiinflammatory role for andrographolide in asthma via inhibition of the nuclear factor-kappaB pathway.

RATIONALE: Persistent activation of nuclear factor (NF)-kappaB has been associated with the development of asthma. Andrographolide, the principal active component of the medicinal plant Andrographis paniculata, has been shown to inhibit NF-kappaB activity. OBJECTIVES: We hypothesized that andrographolide may attenuate allergic asthma via inhibition of the NF-kappaB signaling pathway. METHODS: BALB/c mice sensitized and challenged with ovalbumin (OVA) developed airway inflammation. Bronchoalveolar lavage fluid was assessed for total and differential cell counts, and cytokine and chemokine levels. Serum IgE levels were also determined. Lung tissues were examined for cell infiltration and mucus hypersecretion, and the expression of inflammatory biomarkers. Airway hyperresponsiveness was monitored by direct airway resistance analysis. MEASUREMENTS AND MAIN RESULTS: Andrographolide dose-dependently inhibited OVA-induced increases in total cell count, eosinophil count, and IL-4, IL-5, and IL-13 levels recovered in bronchoalveolar lavage fluid, and reduced serum level of OVA-specific IgE. It attenuated OVA-induced lung tissue eosinophilia and airway mucus production, mRNA expression of E-selectin, chitinases, Muc5ac, and inducible nitric oxide synthase in lung tissues, and airway hyperresponsiveness to methacholine. In normal human bronchial epithelial cells, andrographolide blocked tumor necrosis factor-alpha-induced phosphorylation of inhibitory kappaB kinase-beta, and downstream inhibitory kappaB alpha degradation, p65 subunit of NF-kappaB phosphorylation, and p65 nuclear translocation and DNA-binding activity. Similarly, andrographolide blocked p65 nuclear translocation and DNA-binding activity in the nuclear extracts from lung tissues of OVA-challenged mice. CONCLUSIONS: Our findings implicate a potential therapeutic value of andrographolide in the treatment of asthma and it may act by inhibiting the NF-kappaB pathway at the level of inhibitory kappaB kinase-beta activation.

Multicenter clinical study on Fuzhenghuayu capsule against liver fibrosis due to chronic hepatitis B.

AIM: To study the efficacy and safety of Fuzhenghuayu capsule (FZHY capsule, a capsule for strengthening body resistance to remove blood stasis) against liver fibrosis due to chronic hepatitis B. METHODS: Multicenter, randomized, double blinded and parallel control experiment was conducted in patients (aged from 18 to 65 years) with liver fibrosis due to chronic hepatitis B. Hepatic histologic changes and HBV markers were examined at wk 0 and 24 during treatment. Serologic parameters (HA, LM, P-III-P, IV-C) were determined and B ultrasound examination of the spleen and liver was performed at wk 0, 12 and 24. Liver function (liver function and serologic parameters for liver fibrosis) was observed at wk 0, 6, 12, 18 and 24. Blood and urine routine test, renal function and ECG were examined before and after treatment. RESULTS: There was no significant difference between experimental group (110 cases) and control group (106 cases) in demographic features, vital signs, course of illness, history for drug anaphylaxis and previous therapy, liver function, serologic parameters for liver fibrosis, liver histologic examination (99 cases in experimental group, 96 cases in control group), HBV markers, and renal function. According to the criteria for liver fibrosis staging, mean score of fibrotic stage(s) in experimental group after treatment (1.80) decreased significantly compared to the previous treatment (2.33, P<0.05), but there was no significant difference in mean score of fibrotic stage(s) (2.11 and 2.14 respectively). There was a significant difference in reverse rate between experimental group (52%) and control group (23.3%) in liver biopsy. With marked effect on decreasing the mean value of inflammatory activity and score of inflammation (P<0.05), Fuzhenghuayu capsule had rather good effects on inhibiting inflammatory activity and was superior to that of Heluoshugan capsule. Compared to that of pretreatment, there was a significant decrease in HA, LM, P-III-P and IV-C content in experimental group after 12 and 24 wk of treatment. The difference in HA, LM, P-III-P and IV-C content between 12 and 24 wk of treatment and pretreatment in experimental group was significantly greater than that in control group (P<0.01-0.05). The effect, defined as two of four parameters lowering more than 30% of the baseline, was 72.7% in experimental group and 27.4% in control group (P<0.01). Obvious improvement in serum Alb, ALT, AST and GGT was seen in two groups. Compared to that of control group, marked improvement in GGT and Alb was seen in experimental group (P<0.05). The effective rate of improvement in serum ALT was 72.7% in experimental group and 59.4% in control group. No significant difference was seen in blood and urine routine and ECG before and after treatment. There was also no significant difference in stable rate in ALT and serologic parameters for liver fibrosis between experimental group and control group after 12 wk of withdrawal. CONCLUSION: Fuzhenghuayu capsule has good therapeutic effects on alleviating liver fibrosis due to chronic hepatitis B without any adverse effect and is superior to that of Heluoshugan capsule.
