Sequential Treatment with Syndrome Differentiation on Children's Refractory Nephrotic Syndrome with Yiqi Huayu Qingre Prescription / 中国实验方剂学杂志

ObjectiveTo evaluate the clinical efficacy of sequential syndrome differentiation of Yiqi Huayu Qingre prescription （YHQ） in the treatment of refractory nephrotic syndrome in children. MethodA total of 112 children with refractory nephrotic syndrome were randomly divided into an observation group （57 cases） and a control group（55 cases）. The children in the control group were treated with prednisone tablets combined with tacrolimus，and those in the observation group were treated with YHQ by sequential syndrome differentiation on the basis of the control group. The total effective rates of the two groups after treatment were observed. The 24-hour urinary total protein（24 h UTP），plasma albumin（ALB），cholesterol（CHO），triglycerides（TG）， and traditional Chinese medicine quality of life scale scores before treatment and after four weeks，eight weeks，16 weeks，24 weeks，32 weeks，40 weeks，and 52 weeks in the two groups were recorded. The total course of treatment and the total accumulation of hormones were compared among the children with reduced or no hormone treatment till 52 weeks during treatment. ResultThe total effective rate in the observation group was higher （Z=-2.052，P<0.05）. The observation group had lower 24 h UTP and higher ALB at each follow-up time point than the control group（P<0.05，P<0.01）. At four weeks，eight weeks，and 16 weeks of treatment，there was no statistically significant difference in CHO between the observation group and the control group，and the observation group was lower than the control group in CHO at the rest of the time points （P<0.05，P<0.01）. For TG， the observation group was not significantly different from the control group at four weeks，eight weeks，16 weeks，and 40 weeks of treatment，but lower at 24，32，and 52 weeks （P<0.05，P<0.01）. The total treatment course of hormones in the observation group was shorter（P<0.01）， with less total accumulation（P<0.01）. At different follow-up time points，the total score of traditional Chinese medicine quality of life scale in the observation group was superior to that in the control group（P<0.05，P<0.01），and the scores of the observation group in the four dimensions （physiological function，independent factor，social factor，and psychological factor） after treatment were higher than those in the control group（P<0.05，P<0.01）. ConclusionYHQ under sequential syndrome differentiation has a definite clinical effect in treating children with refractory nephrotic syndrome. It has advantages in shortening the total course of hormone treatment and reducing the total accumulation of hormones，and can improve the quality of life of children with refractory nephrotic syndrome.

Effects of Electroacupuncture on Brain Function of APP/PS1 Mice: A Functional Magnetic Resonance Imaging Study / 中国康复理论与实践

Objective:To investigate the effects of electroacupuncture at Baihui (DU20) and Shenting (DU24) on brain function of APP/PS1 mice. Methods:Sixteen 4-month-old APP/PS1 mice in the same litter were randomly divided into model group (n = 8) and electroacupuncture group (n = 8). Eight transgenic negative mice in the same litter were as control group. The electroacupuncture group accepted electroacupuncture at Baihui and Shenting for 16 weeks. They were assessed with Object Recognition Test before and after intervention, and observed under small animal functional magnetic resonance imaging with regional homogeneity (ReHo) analysis. Results:Compared with the control group, the discrimination ratio decreased in the model group after intervention (P < 0.05), while it increased in the electroacupuncture group compared with that in the model group (P < 0.05). Compared with the control group, ReHo of right basal forebrain and left hippocampus decreased in the model group before intervention. Compared with the control group, ReHo decreased in bilateral hippocampus group and increased in retrosplenial cortex in the model group after intervention; while it increased in bilateral hippocampus and motor cortex and decreased in anterior cingulate gyrus in the electroacupuncture group compared with that in the model group. Conclusion:Electroacupuncture at Baihui and Shenting may delay the decline of learning and memory ability in Alzheimer's disease model mice, which may relate to the regulation of functional activities in hippocampus.

Primary understanding of syndrome differentiation treatment of COVID-19 with traditional Chinese medicine based on 3-5 edition of Diagnosis and Treatment of Novel Coronavirus Pneumonia and ancient literatures / 中草药

There are an increasing number of patients suffering from coronavirus disease 2019 (COVID-19) in our country and overseas. After the outbreak, the state health administrative sections have updated steadily several editions of Diagnosis and Treatment of Novel Coronavirus Pneumonia. According to the change of exposition of traditional Chinese medicine (TCM) treatment in these editions and the characteristics of cases in clinic, COVID-19 corresponds to pestilence category of TCM, which also based on the ancient literatures from the seasonal-febrile-disease subject of TCM. The disease contributes to pestilential pathogen caused by specifically regional climate characteristics of Wuhan city. It is important for COVID-19 patients to eliminate pathogens as soon as possible, which should apply defense-qi-nutrient-blood diagnosis to different courses of disease. The TCM therapy should be established according to the different organs where the virus lives and characters. In order to control the epidemic at an early date, it is necessary to consider the local conditions and use the combination of traditional Chinese and western medicine to treat COVID -19 patients.

<p><b>OBJECTIVE</b>To assess the beneficial and adverse effects of Wendan Decoction (温胆汤, WDD) for the treatment of schizophrenia.</p><p><b>METHODS</b>Five electronic databases were searched until May 2014, including the Chinese National Knowledge Infrastructure, the Chinese Biomedical Literature Database, the Chinese Scientist Journal Database, PubMed, and the Cochrane Central Register of Controlled Trials in the Cochrane Library. The randomized controlled trials (RCTs) testing WDD against placebo, antipsychotic drugs, or WDD combined with antipsychotic drugs against antipsychotic drugs alone were included. Study selection, data extraction, quality assessment, and data analyses were conducted according to the Cochrane standards.</p><p><b>RESULTS</b>Thirteen RCTs (involving 1,174 patients) were included and the methodological quality was evaluated as generally low. The pooled results showed that WDD combined with antipsychotic drugs were more effective in clinical comprehensive effect, Positive and Negative Syndrome Scale (PANSS) scores and Brief Psychiatric Rating Scale scores compared with antipsychotic drugs alone. However, WDD had less effectiveness compared with antipsychotics in clinical comprehensive effect; and WDD was not different from antipsychotic drugs for PANSS scores. The side effects were significantly reduced in the intervention group compared with the control group.</p><p><b>CONCLUSIONS</b>WDD appears to be effective on improving symptoms in patients with schizophrenia. However, due to poor methodological quality in the majority of the included trials, the potential benefit from WDD needs to be confirmed in rigorous trials and the design and reporting of trials should follow the international standards.</p>

Peptides analysis in digested edible bird's nest by HPLC-MS / 中国中药杂志

Edible bird's nest contains lots of glycoproteins. The glycosylation inhomogeneity for glycoprotein often results in wide range of molecular weight and the difficulty for protein separation and charaterization. In this paper, proteins in the edible bird's nest were extracted using multiple extractions, and then digested by PNgase F and trypsin. The digest mixture was separated with HPLC, and peptides were identified based on MS/MS data searching. The results indicated that the extracted proteins were amount to 79.7% of total protein in the edible bird's nest. More than 20 species of peptides in the digested mixture were identified. The sequences of these peptides showed similarity with some proteins from Swiss-prot. The research indicated that deglycosylation, tryptic digestion coupled with HPLC-MS/MS is a proper strategy for characterization of proteins in the edible bird's nest.

[Effect of total flaveos of Gymostemma pentaphyllum on protein expression of Fas/FasL genes and TNF-alpha concentration in cultured neonatal rat cardiomyocytes with hypoxia-reoxygenation].

OBJECTIVE: To study the effect of total flaveos of Gymostemma pentaphyllum on the protein expression of apoptosis-associated Fas/FasL gene and tumor necrosis factor-alpha (TNF-alpha) concentration in cultured neonatal rat cardiomyocytes with hypoxia-reoxygenation (H/R). METHOD: A cultured primary neonatal rat cardiomyocytes model with H/R was erected, experiments were divided into six groups, (1)control group, (2)H/R group, (3)15 mg x L(-1) TFG plus H/R group, (4)45 mg x L(-1) TFG plus H/R group, (5) 105 mg x L(-1) TFG plus H/R group, (6)105 mg x L(-1) TFG group. TNF-aconcentration in cultured cardiomyocytes with H/R, was determined by ELISA method, the protein expression of Fas/FasL genes were estimated by immunohisto-chemistry. RESULT: After cardiomyocytes were made with H/R, Compared with control group, the positive expression index (PEI) of Fas/FasL proteins in cardiomyocytes increased significantly, Compared with H/R groups, the PEI of Fas/FasL proteins were lower significantly in groups with different dosages of TFG (P < 0.05). TFG inhibited the secretion of TNF-alpha from myocardial cells and increased the survival rate of myocardial cells. CONCLUSION: The protein expression of apoptosis-associated Fas/FasL genes increased during H/R. The TFG can protect myocardium against H/R injury by decreasing the production of TNF-alpha, downregulating the protein expression of Fas/FasL genes, and then inhibiting myocyte apoptosis.
