Objective: To study the resources of G. leuco c arpa var. yunnanensis for further develop ment of this drug. M ethod:field in vestigating, consulting with relevant experts and looking into available spec imens. Result and C onclusion:G. leucocarpa var. yunnanensis is widely distributed in the so uthern regions of the Yangtze River. The field investigation suggests that the distribution ce nter is situated in Yunnan province, mainly in Kunming, Chuxiong and Dali counti es. The climate in these areas is moderate and moist. G. leucocarpa var. yunnanensis is not a dominant species in this natural environment. In som e places, it grows with other species of Gaultheria , such as G. fragrantissima, G. tetramera, G. griffithiana and G. leucocarpa var. cumingiana. It is di stributed at altitudes from 400 m to 3 500 m. Accustomed to different sunshine conditions, G. leucocarpa var. yunnanensis prefers stronger sunlight and commonly grows on sunny slopes, seldom in dense forest, propagating itself by roots. As a folk medicine, G. leucocarpa var. yunnanensis is commonl y used t o treat rheumatic arthritis(RA), dazzling, suppressed menstruation, cold, cough, asthma, strain hematemesis, eczema, ascites, wound, amebic dysenter y, acute and chronic prostatitis. It is suggested that further pharmacological a nd clinical researches of this plant be concentrat ed on the treatment of RA and relief of aches.

In this study, a novel resequencing pathogen microarray (RPM)-based multi-pathogen detection assay was developed to simultaneously detect 14 rotaviruses, 7 caliciviruses, 8 astroviruses, 28 enteroviruses, and 16 rare diarrhea viruses in patients with diarrhea syndrome. The specificity of the assay was examined using confirmed virus-positive specimens, and the sensitivity was evaluated by serial ten-fold dilutions of in vitro transcribed RNA. RPM assay could detect and differentiate virus types/subtypes at 20-2000 copies/microL. The detection threshold of RPM was determined by adjusting the reference concentration, and the detection steps were optimized to type Enterovirus. The nucleic acids of 10 stool samples from patients with unexplained diarrhea were screened, and 6 of them showed positive results. The RPM results were further verified by singleplex PCR followed by sequencing, and no difference was found between the two assays. In conclusion, we have established a high-throughput RPM assay with high specificity and sensitivity, which demonstrates a great potential for the identification of pathogens in patients with unexplained diarrhea and the management of emerging epidemic.

Guanylate-binding protein 1 (GBP1) is an interferon induced protein, that belongs to the guany late-binding protein family. GBP1 is widely involved in anti-infection immune responses, anti-tumor activity and various biological reactions. Recent studies have proved that IFN-alpha, IFN-beta, IFN-gamma, IL1alpha, IL1beta, TNF-alpha and LPS can induce GBP1 expression; hence, the diverse biological functions of GBP1 have been gradually deduced and exploited. Many studies have been performed over recent years to understand the exact mechanisms that underlie the anti-infection and anti-tumor properties of GBP1. This review describes the molecular structure, biological activity, anti-infective properties and other functions of GBP1, in order to provide insights into the divergent roles of GBP1 in the regulation of various biological processes.

OBJECTIVETo investigate the pathogenesis of globozoospermia, fertilization ability of round-headed sperm, and the application value of assisted oocyte activation in intracytoplasmic sperm injection (ICSI) for the wives of glohozoospermia men.
METHODSWe collected oocytes from the wives of 2 globozoospermia patients and randomly divided them into two groups after ICSI to receive calcium ionophore A23187-activation and conventional treatment, respectively. We reviewed the relevant literature published at home and abroad, and discussed the etiology of globozoospermia, fertilization ability of round-headed sperm, and treatment options for this disease.
RESULTSQuality embryos were obtained in the A23187-activation group while no fertilized oocytes, oocyte cleavage, quality embryos, or blastular formation were found in the conventional treatment group. Both women achieved pregnancy and gave birth to healthy neonates after transfer of the quality embryos from the A23187-activation group.
CONCLUSIONCalcium ionophore A23187 can be applied to ICSI for the wives of globozoospermia men and bring about desirable clinical outcomes. Meanwhile, attention should be paid to its safety.

Objective:To further develop Gaultheria leucocarpa var. yunnanensis,anti-bacteria constituents in it were screeened. Method:The constituents were extracted by chromatographic process.The anti-bacteria test was made with regulatory method of analysis. Result and conclusion: Anti-bacteria test with extracts of water, acetic ester and n-butanol showed that 3 extracts from 22 samples had anti-Staphylococcus aureus action, and the extracts from root and stem showed the same result. 2 extracts could kill Escherichia coli and Pseudomonas aeruginosa. The lower the concentrate, the less the anti-bacteria action was. These results suggested that not only essential oil but other ingredients from G.leucocarpa var. yunnanensis have anti-bacteria activity . Anti-fungi test of the same extracts didn't indicate remarkable action.

OBJECTIVETo investigate the proper anticoagulation intensity in patients after mechanical heart valve replacement in china.
METHODSThe anticoagulation therapy intensity and the complications in 480 patients after mechanical heart valve replacement were studied.
RESULTSThe follow-up rate was 89.17%, the total patient-years (Pty) was 2,110.04 years, the mean oral import warfarin dosage was (2.81 +/- 0.95) mg/day, and native warfarin dosage (2.38 +/- 0.46) mg/day. The mean PTR value of 2 116 samples was 1.43 +/- 0.26, and the INR value of 1 195 samples was 1.63 +/- 0.49. The total hemorrhage rate was 4.60% Pty, and the hemorrhage death rate was 0.38% Pty. The PTR and INR values were higher in the hemorrhage group than in the no-hemorrhage group. (t = 1.816, P < 0.05; t = 2.407, P < 0.01). The thromboembolism rate was 0.66% Pty, and the thromboembolism death rate was 0.05% Pty. There were 15 pregnancies in 14 women patients and no malformed newborns were found.
CONCLUSIONSThe most important complication of anticoagulation therapy after mechanical heart valve replacement is hemorrhage in china; The proper anticoagulation intensities of this group are INR 1.5-2.0 and PTR 1.3-1.5. It is beneficial to adopt the low intensity anticoagulation therapy for decreasing the death rate from hemorrhage, protecting pregnant women and newborns from hemorrhage and malformation, and improving the life qualities of the patients.
