1.Mutual information-based correlation analysis of herbs against insomnia.
China Journal of Chinese Materia Medica 2015;40(19):3873-3877
This paper aims to analyze Professor Guo Rongjuan's medication experience on insomnia therapy based on the Traditional Chinese Medicine (TCM) Inheritance Support Plat. First, TCM formulae prescribed by Professor Guo for insomnia therapy were collected from the TCM Inheritance Support Plat. Next, unsupervised data mining algorithms, including apriori, modified mutual-information, and entropy clustering of complex system were applied to obtain the frequencies for different herbs and identify the association rules among the herbs. Accordingly, we can gain new insights into Professor Guo's medication experience on insomnia therapy. Based on analysis of 3 084 formulae, we determined the frequencies for herbs in the formulae and identified the association rules among these herbs. At last, 41 core combinations and 7 new formulae were obtained. The identified medication experience conform with Professor Guo's views on the etiology and pathogenesis of insomnia: "pathogenic fire derived from stagnation of liver-QI (Gan Yu Hua Huo)" is the core pathogenesis of insomnia; "liver stagnation and spleen deficiency" and "chronic illness transferred to kidney" are the main features for insomnia. The TCM Inheritance Support Plat is of great practical value for mining clinical experience of famous TCM doctors.

Snake antivenomimmunoglobulins are considered to be the most efficient drugs in snake envenomings. Most snake antivenomimmunoglobulins all over the world are still prepared by fragmentation of polyclonal antibodies isolated from hyper-immunized horse serum till now. In this review, we retrospect the history of snake antivenomimmunoglobulins, analysis the present situation and pay the close attention on the key technological links in the process of research and manufacturing, such as properties of IgG and its fragments, selection and preparation of immunogen, optimization of immunization schedule and protein isolation and purification, which can be available for the reference in the research and development of snake antivenom.

Objective To analyze the prognostic value of baseline serum free light chain (sFLC) in light-chain (AL) cardiac amyloidosis.Methods Twenty-seven patients with AL cardiac amyloidosis were retrospectively reviewed from January 2014 to January 2015.sFLC was measured by immuoturbidimetric assay.Baseline characteristics,echocardiographic parameters and electrocardiogram data were analyzed.According to the median baseline dFLC (involved sFLC minus uninvolved sFLC),patients were categorized into either the low dFLC(≤307mg/L) or the high dFLC group (>307mg/L).Results More subjects in the high dFLC group with early/late diastolic mitral velocity ratio (E/A ratio) over 2 (71.4% vs 30.8%,P =0.035),and subjects in this group had a shorter median survival time than those in the low dFLC group (3 months vs 17 months,P =0.004).A similar phenomenon for median survival time was observed when the subjects were redivided either by a new cut-off value of 180mg/L for dFLC (low dFLC group:17 months;high dFLC group:4 months,P =0.014) or a κ/λ ratio,in which subjects with κ type sFLC-ratio ≤ 19.6 and λ type sFLC-ratio >0.065 were in the low sFLC-ratio group (17 months) and those with κ type sFLC-ratio > 19.6 and λ type sFLC-ratio ≤0.065 were in the high sFLC-ratio group (4 months,P=0.023).In multivariate analysis,dFLC and New York Heart Association (NYHA) classification of cardiac function were two risk factors associated with all-cause mortality in patients,among which the hazard ratio for higher dFLC was 4.28 (95% CI 1.55-11.8,P =0.005).Conclusion The level of sFLC could be a marker for the prognosis of AL cardiac amyloidosis.

The Medical Healthcare Service Center,located at the Youxian District,Mianyang City of Sichuan Province,successfully rescued the people affected by the Wenchuan earthquake and the Tangjiashan barrier lake with great help from the senior hospitals.We suggest that the community healthcare service center could play an important role in emergency response system.
