Objective To establish the quality standard for Tianqi Granule.Methods Radix Notoginseng in Tianqi Granule was identified by TLC.The ginsenoside Rg1 and notoginsenoide R1 in Tianqi were determined by HPLC.Result Radix Notoginseng could be identified by TLC.The linear ranges of ginsenoside Rg1 and notoginsenoide R1 were at 0.628～5.652 ?g(r =0.999 8)and 0.155～1.395 ?g(r =0.999 8),respectively.The average recoveries were 99.24%(RSD=0.84%)and 99.14%(RSD=1.13%).Conclusion The method is simple,accurate and with good reproducibility and high precision,and can be used for quality control of Tianqi Granule.

The feasibility of frontal chromatography for determining the complexation stability constant KML and total mole of binding site Λo was demonstrated by the accuracy and precision binding experiments between metal ions (Cu2+, Ni2+ and Co2+) and chelating ligand (IDA), in which R2>0.98 and RSD <5%.To further prove the universality of the frontal chromatography, the changing rules of KML values between Cu2+, Ni2+, Co2+ and IDA, Asp, L-Glu were examined under NaAc-HAc, Na-PB and Tris-HCl buffer systems.The results showed that the binding strength of chelating ligands for metal ions followed IDA>Asp>Glu;binding strength of metal ions for chelate ligands followed Cu2+>Ni2+>Co2+;and the binding effect with NaAc-HAc buffer was the best.In aqueous solution, quantum computing of binding energy (ΔE) and gibbs free energy (ΔG) between chelating ligand and metal ion was performed at the M06/6-311++G (d, p) level.According to ΔE and ΔG, the binding rules between chelating ligand and metal ion were predicted theoretically.These rules were basically in agreement with above experimental results.The present work provided effective method for studying on binding characteristics of metal ions for aminocarboxyl chelating ligands, thus exhibited a good foundation for improving the stability of immobilized metal affinity chromatographic column and solving the leakage of metal ions from the column in the process of competitive elution.

Objective To investigate the intervention ways of endoscopes in the treatment of esophagus stenosis due to carcinoma of esophagus and improvement of quality. Method 11 cases of advanced carcinoma of esophagus were included in this study. Operation and chemical therapy were unavailable for these patients. Memory trestle with membrane and made of alloy of Nickel－ titanium was inserted under intervention of endoscope. Trestle was posed in stenosis part of esophagus under direction of X－ ray. Trestle could be dilated 3－ 7 days after operation due to its reaction characteristics to temperature. So, redilated therapy was unnecessary. Trestle could reconstruct swallowing tract and made feeding through mouth become available during limited survival time.Results All trestles were successfully inserted.Half－ fluid feeding was available after operation. Obstruction was removed in all patients(100％ ).Conclusion Method described in this study was safe and effective .Effective swallowing tracts were reconstructed in all patients after trestle was planted and quality of life and survival time were both improved.

Objective To investigate the security characteristics of rural young boarding pupils and its influencing factors.Methods 210 boarding and 265 non-boarding rural young pupils of Huojia in Henan were tested by questionnaires,including of a self-developed questionnaire,security questionnaire and adolescent mental resilience scale.Results ①The scores of the interpersonal security (25.99 ± 5.53),the determine control sense factor (24.63 ±6.17) and the total security(50.62 ± 10.37) in the boarding pupils were statistically lower than non-boarding pupils (27.36 ± 6.38,26.00 ± 6.55,53.36 ± 11.77,P ＜0.05).②There were statistically significant difference in the scores of the interpersonal security,the determine control sense factor and the total security among the different grades(P＜0.05),but there were no statistically sex difference in the scores(P ＞ 0.05).③Group regression analysis showed that,no family factors in the young boarding pupils had influence on the score of the security sense factors and the total (P＞0.05),and marital relationship of parents,only child,father' s and mother(')s education background of non-boarding pupils had certain influence on the score of the interpersonal security,the determine control sense factor and the total security (β =-0.43-0.27,P＜ 0.05).④The group regression analysis showed that,the problem solving and self-efficacy,parents'high expectations in mental toughness respectively had some effect on the interpersonal security of boarding and non-boarding pupils(β =-0.15,β =0.25,P＜0.05),and social ability and family care,schools resilience respectively had influence on the determine control sense in boarding and non-boarding pupils (β =-2.91-2.87,P＜0.05),and social ability,parents'high expectations respectively had influence on the total security in boarding and non-boarding pupils (β =-0.17,β=0.22,P＜0.05).Conclusion The security-sense in boarding young pupils are lower than the non-boarding young pupils,and family factors and mental toughness have different effects on security-sense of two kinds pupils.

Objective To investigate the clinical significance of IL-27 in hepatocellular carcinoma ( HCC) in the early stage , and to compare it with alpha-fetoprotein ( AFP) in diagnostic performance .Methods Enzyme-linked immunosorbent assay was used to detect the serum level of IL-27 in the HCC group and control group .Receiver operator characteristic ( ROC) curve was used to ana-lyze two indicators and the logistic regression model predicted value ( PRE) was obtained .Results The study indicated the concentra-tion of IL-27 in HCC group [(364.19 ±177.55)pg/ml] was significantly higher than the control group [(255.49 ±94.33)pg/ml], the area under the curve (AUC) of IL-27 and AFP were (0.804) and (0.818), respectively.Logistic regression obtained the regres-sion model PRE that contains AFP and IL-27, with a predicted area under the ROC curve for HCC (0.901), while the diagnostic sen-sitivity (84.8%) and specificity (96.7%) were significantly higher than the capability of individual diagnosis of each indicator .Con-clusions In this study we obtained the model which can be used for clinical diagnosis of hepatocellular carcinoma in future .

3), the intra-day RSD was less than 10% and the inter-day RSD was less than 12%. The average recovery stood at 86.96%. CONCLUSION: The established method is simple, rapid, precise and suitable for the determination and pharmacological study of faropenem in human plasma.

With more and more attention and investment on acupuncture scientific researches, considerable outcomes and achievements has been acquired, but the shortcoming of low transformation rate of acupuncture research achievements is gradually exposed. Nowadays there is no related report on this problem, so based on achievement translational research in other areas and practical situation of acupuncture, the existing problems and solutions are analyzed. As a result, the existing problems include (1) the research content is mainly basic research and clinical research but less acupuncture device research, leading to limited transformation efficiency; (2) the evaluation system and transformation pattern are still needed to be perfect. The solutions are (1) to properly evaluate the research achievements of acupuncture, (2) to advocate the concept and method of translational medicine, (3) to reform the policy and system, and (4) to establish valid platforms covering research, outcomes and transformation.
