This study was aimed to determinate the content of quercetin from different parts (such as flowers, fruits, stems, leaves and branches) of Penthorum chinense Pursh. from Sichuan province so as to offer reference for the comprehensivedeve lopment and utilization of P. chinense Pursh. The quantitative determination of quercetin from five groups of different parts of P. chinense Pursh. were carried out and put into comparison by the reversed-phase high performance liquid chromatography (RP-HPLC). The results showed that there were larger differences of content among different parts. The highest content of the medical parts were flowers and fruits, which was followed by the leaves, stems and branches. It was concluded that different parts (such as flowers, fruits, stems, leaves and branches) of P. chinense Pursh. from Sichuan province should be divided in the clinical and productive practice, which was to supply the scientific basis for enhancing the curative effect and reasonable exploitation and utilization of the resource of P. chinense Pursh.

This study was aimed to analyze the influence of specific clinical effect of Dioscorea opposita Thunb. by dosage in order to summarize its rules. Recordings on pills containing D. opposita Thunb. from the classic prescrip-tion of the Formula Dictionary of Traditional Chinese Medicine were collected. Dosage of D. opposita Thunb. was used as the cardinal line. EXcellwas used to conduct schematic analysis. The results showed that small amount of D. opposita Thunb. had the effect of reinforcing the spleen. The effect of tonifying the lung had the dosage boundary line of 10 g. The small dosage had weak effect and large dosage had strong effect. The effect of tonifying the kidney was often the middle dosage. When the dose was larger or smaller, the effect was not obvious. The effect of consoli-dating the kidney was obvious when using larger or smaller dosage. It was concluded that the dosage of D. opposita Thunb. had relatively big influence on its effect, which provided reference of more value for the clinical practice and health cultivation.

Objective To observe the clinical effects of puerarin injection combined with reduced glutathione in the treatment of stage Ⅲ of diabetic nephropathy.Methods One hundred inpatients with stage Ⅲ of diabetic nephropathy in the Chongqing Municipal Hospital of Traditional Chinese Medicine from January 2015 to October 2016 were selected and divided into the observation group and control group according to the random number table method,50 cases in each group.Both groups took the basic therapy of controlling blood sugar,blood lipids and blood pressure.On the basis of general treatment,the control group was added with reduced glutathione injection 1.8 g/d,while on the basis of the control treatment,the observation group was added with puerarin injection 300 mg/d.Both groups were treated for 4 weeks.Fasting plasma glucose (FPG),2 h postprandial plasma glucose (2 h PG),blood pressure,blood fat,serum creatinine(SCr),blood urea nitrogen (BUN),24 h urinary total protein,urine albumin,urine β2 micro-globulin (β2-MG),NAG,and other indicators before and after treatment were detected in the two groups.Results FPG,2 h PG,blood pressure and blood fat after treatment in the observation group and control group were improved,but the improvement in the observation group was better than that in the control group (P＜0.05);the levels of SCr,BUN,24 h urine protein,urine albumin and β2 micro-globulin and urine NAG in the observation group and control group patients were reduced to some extent(P＜ 0.05),which were significantly improved compared with before treatment (P＜0.05),but the improvement degree in the observation group were better than that in the control group (P＜0.05).Conclusion Puerarin injection combined with reduced glutathione injection has obvious therapeutic effect in treating the stageⅢ of diabetic nephropathy,and has less adverse reactions,is safe and effective and can be promoted and applied in clinic.

Objective To investigate the application effects of milk protein challenge test and serum specific IgE antibody de-tection in children with milk protein allergic diseases.Methods 76 cases of children with milk protein allergic diseases of North Hospital of the People’s Hospital in Urumqi City from January,2013 to December,2015 were treated with milk pro-tein challenge test.The clinical characteristics,results of milk protein challenge test and serum IgE antibody detection,and the value change of routine blood indexes were analysed and compared.Results Diarrhea and hematochezia were the most common clinical features,vomiting,hematemesis and abdominal distention were rare.47 cases (61.8%)showed positive re-sults in milk protein challenge test,and 29 cases (38.2%)showed negative results.42 cases of positive children had delayed allergy,and 5 cases showed rapid allergy.Compared with the negative group,the positive rate of serum specific IgE antibody in positive group didn’t change obviously,the difference was not statistically significant (14.9% vs 6.9%,χ2=0.466,P>0.05).The neutrophil count in positive group was higher after challenge than that of before challenge (t=2.480,P<0.05). The number change of blood cell,neutrophil and platelet in positive group were no statistical differences compared with those in negative group (t=0.500,1.395,0.296,all P>0.05).Conclusion Diarrhea and hematochezia were the most commom disease of digestive tract in children with milk protein allergic diseases.It is necessary to perform milk protein challenge test in clinical practice,however,serum specific IgE antibody is not considered as its diangnosis basis.

As the actual clinical reflecting of transform Chinese medicine special curative effect, Chinese medicine preparation not only satisfies the need of hospital clinic, scientific research and teaching, but also plays an important role in deepening medical and health system reform, improving people's health level and contributing to the economic growth. However, some problems about administration and approval (tending to western medicine), contraction of the scale, lack of synchronization for clinic and scientific research, and the imbalance of regional development make Chinese medicine preparation move forwards slowly in contradiction. It has not only reduced the effectiveness of the Chinese medicine preparation in hospital clinic, but also brought bad effect on modernized development of Chinese medicine preparation. Research shows that main influencing factors of status quo of Chinese medicine preparation in medical institution include imperfect laws and regulations, high cost than income, and shortage of talents in preparation research. The analysis indicated that the necessary measures to break the contradiction, improve clinical effect of Chinese medicine, and promote the modernization development of Chinese drugs preparation were as follows: government and related departments should strengthen the supporting force in policy by adjusting the examination and approval policy, speeding up dispensing use, reforming pricing system, including into medicare reimbursement, integrating advantage resources and so on; medical institution should actively carry out research and development of traditional Chinese Medicine through drawing the traditional and modern essence, reserving professional talents, and developing characteristic preparation; companies cooperate with hospitals for complementary advantages, which can rapidly transform Chinese medicine preparation into clinical practice.

The research was carried out to establish HPLC fingerprints of Tibetan medicinal herb "Songdi" (Saxifraga umbellulata var. pectinata), and to provide reference for identification an quality control of it. It was performed on an Amethyst-C18-P (4.6 mm x 250 mm, 5 microm) column with the mobile phase of methanol-0.4% formic acid in a linear gradient mode at a flow rate of 1.0 mL x min(-1). The column temperature was 30 degrees C, and the detection wavelength was set at 254 nm. The software for chromatographic fingerprint was applied to analyse the pattern analysis, the common peaks and similarity. Cluster analysis was done based on the common peaks data of 33 samples from different plant species and sources by SPSS software. Ten common chromatographic peaks were identified by fingerprint, showing a low similarity in constituent and variety. Flavonoids and saponins were the principal components. The number and area of peaks were affected by the collection sources and method. The high similarity are showed by the samples derived from the same area with high accuracy and high purity. The method is so simple, exclusive, stable and high repeatable that it can provide reference for identification and quality assessment of "Songdi" (S. umbellulata var. pectinata).
