Objective To evaluate the clinical value of the quantitative detection of plasma 1,3-β-D-glucan in penicilliposis marneffei. Methods The 1,3-β-D-glucan concentrations were detected by using a G test. Results In 60 New Zealand rabbits infected by Penicillium marneffei,the levels of 1,3-β-D-glucan were positively correlated with infectious severity. The sensitivity, specificity, positive predictive rate and negative predictive rate were 88.3%、100%、 100% and 58.8% respectively,which were significantly higher than those of the control group(P <0.01 ).Conclusion The quantitative method for the detection of 1,3-β-D-glucan in plasma was simple,sensitive and reliable, and could be used as the assisting diagnosis of penicilliposis marneffei at early stage.

Objective To study the protective effects of ?-asarone on PC12 cells damage induced by Glutamate. Method The effects of ?-asarone on PC12 cells after Glutamate intoxication on morphology, extent of damage, livability, intracellular calcium concentration and apoptosis ratio were observed. Result Morphological changes, LDH leakage and intracellular calcium concentration increasing, and cell survival decreasing were observed in PC12 cells exposured to Glutamate. 7.5, 15, 30 ?g/mL?-asarone can increase cell survival, decrease LDH leakage. 15, 30 ?g/mL ?-asarone can reduce intracellular calcium concentration and apoptosis ratio. Conclusion ?-asarone prevents the toxicity of Glutamate, and it maybe attribute to its effect of anticalcium.

Objective To compare the therapeutic efficacy of reteplase(r-PA) and alteplase(t-PA) in the high risk patients with pulmonary embolism during a pulmonary artery catheter broken bolt in the interventional treatment,and to evaluate the clinical safety.Methods 54 high risk patients were selected as the research subjects,and they were randomly divided into treatment group(24 patients) and control group(30 patients).Patients in both two groups were given general treatment,low molecular heparin sodium anticoagulation therapy.Besides,the control group was given local perfusion thrombolysis enzyme treatment.While the treatment group was given local perfusion at enzyme thrombolysis treatment.Results Two-way Chi-square test results showed that before treatment,there were no significant differences in HR,RF,PaO2,PaCO2 and SaO2 between the two groups(all P>0.05).After 3-day treatment,in the treatment group,HR[(83.39±14.25)times/min],RF[(17.80±1.65)times/min],PaO2[(87.59±7.34)mmHg],PaCO2[(37.60±7.62)mmHg],SaO2[(97.29±6.72)%] in the treatment group group,which in the control group were (97.7±15.51)times/min,(20.49±1.68)times/min,(81.53±6.42)mmHg,(35.69±4.57)mmHg,(93.91±3.27)%,the differences between the two groups were statistically significant(t=8.01,7.33,6.32,all P<0.05).After three days therapy,the total effective rate was 86.67% in the treatment group,which was significantly higher than 75.00% in the control group (x2=1.21,P=0.55).After thrombolysis treatment,there was no significant difference between the treatment group and control group in hemorrhage rate(x2=2.24,P=0.53),which were 13.33% and 12.50%,respectively.Besides,the hemorrhage patients were all got effectively treated and their condition was significantly improved,and none of them occurred severe bleeding during the observation periods in the two groups.Conclusion Local perfusion reteplase therapy in high-risk patients with PE through the pulmonary artery catheter broken bolt in the interventional treatment is safe and is worthy of clinical promotion.

The changes of retinal nuclear DNA content in rats after death was detected and the relationship between degradation of retinal nuclear DNA and postmortem interval (PMI) was analyzed. Ninety healthy adult SD rats, female, weighing 250+/-10 g, were randomly divided into 15 groups. At 20 degrees C, the retinal cells were withdrawn every 2 h within 0 to 28 h after death and stained with Feulgen-Vans. Index of density (ID), integral absorbance (IA) and average absorbance (AA) in retinal nucleus were analyzed by image analysis system. And the obtained data were subjected to linear regression analysis by using SPSS12.0 software. The results showed that in retinal nucleus, AA and IA were gradually declined with the prolongation of PMI, while ID had an increased tendency. Within 28 h after PMI, the regression equations were as follows: Y(AA )=-0.009X(AA )+0.590 (R(2)=0.949), Y(IA )=-0.097X(IA )+18.903 (R(2)=0.968), Y(ID)=0.122X(ID)+2.246 (R(2)=0.951). It was concluded that retinal nuclear DNA after death in rats was degraded gradually and had a good correlation with PMI.

The evidence-based Guidelines of Clinical Practice with Acupuncture and Moxibustion are based on extesiv evidene of literature an compiled by eperience of experts, so the recommended acupoints present special thoughts and laws of compatibility. It is found the traditional acupoint combination methods predominate, such as distal-local acupoint combination, syndrome differentiation-based acupoints combination and symptom-based acupoints combination, etc., and are combined with research achievements of modern medical science;

This article summarized the characteristics and rules of acupoints grouping recorded in Huang Di Nei Jing (Yellow Emperor’s Canon of Internal Medicine), holding that it had passed important concept of acupoints grouping, formed the embryonic form, and brought up basic grouping types including distant and proximal grouping, and interior-exterior grouping, despite the small number of involved acupoints. Besides, it also paid much attention to other factors that may influence the therapeutic efficacy of acupoints grouping. Therefore, Huang Di Nei Jing has played a crucial role in guiding the development of acupoints grouping theories.

Objective To systematically assess the efficacy and safety of electroacupuncture for trigeminal neuralgia. Method Randomized controlled trials of a electroacupuncture treatment for trigeminal neuralgia were sought by a computer search of CNKI,Wan Fang Data,VIP,CBM,PubMed,EMbas and The Cochrane Library.The retrieval time limit was from March 1996 to March 2016. Two reviewers sifted the literature and extracted data independently according to the inclusion and exclusion criteria andthen assessed the riskofbias of the included literatureusing the Cochrane risk of bias assessment tool.Ameta-analysis was made using RevMan 5.3.Result Finally, 12 articles were included with atotal of 847 subjects.The results ofmeta-analysis showed that the total efficacy rate was higher in the electroacupuncture group than in the control group [OR=4.04,95%CI(2.67, 6.13),P<0.00001].There were no statistically significant differences in the VAS score [MD=﹣0.06,95%CI(﹣0.59, 0.47),P=0.82] and the recurrence rate [OR=0.64,95%CI(0.05,7.45),P=0.54] between the electroacupuncture and control groups.Conclusion The currentlimited evidenceshows that the total efficacy rate fortrigeminal neuralgiais higher in the electroacupuncture group than in the control group.There are no statistically significant differences in the VAS score and the recurrence rate of trigeminal neuralgia between the electroacupuncture and control groups of patients.But the conclusions need more high-qualitytrials for validation owing to the limitation of the sample size of the included studies.

Objective To establish a simple, efficient and low-cost method for the detection of Salmonella typhimurium carrying SSeC gene. Methods In this study, a nano-biosensor ( FAM-P/GO) was successfully established based on the noncovalent assembly of carboxy-fluorescein ( FAM)-labeled probe and graphene oxide ( GO) . The target gene at different concentrations and SSeC gene-harbored bacterium sam-ples were detected by the FAM-P/GO nano-biosensor to evaluate its sensitivity. The specificity of the estab-lished nano-biosensor was evaluated by using DNAs with mismatched base pairs and single-stranded DNAs ( ssDNAs) extracted from various species. Results The established strategy for SSeC gene detection showed a good linear range of 0. 05-1. 0 μmol/L (R2=0. 992 1) with a lower limit of 0. 05 μmol/L. Moreover, the lower detection limit for target bacterium samples was 103 CFU/ml and the fluorescence intensity increased linearly with the concentration from 103 CFU/ml to 108 CFU/ml. The signal-to-noise ( S/N) of the experi-mental group was much greater than that of the control group, which indicated that the establish method was highly specific. Conclusion The FAM-P/GO nano-biosensor was successfully established in this study, which provided a new and possible way for the rapid detection of Salmonella typhimurium harboring SSeC gene.
