Objective To observe the effects of green fluorescence protein mediated by lentivirus in bladder, and to de?termine the amount of virus obtained good transfection effects. Methods lentivirus carring GFP gene was perfused using transurethral approach into bladder of guinea pigs. Samples of bladder, liver, kidney and lungs were collected for frozen sec?tions after feeding seven days. The distribution of green fluorescence was observed using laser confocal microscopy. Re?sults The titer of lentivirus was 4 × 108. GFP was found under the mucosa when the amount of lentivirus transurethral was 30μL. GFP was distributed widely in muscle layer using 40μL lentivirus. GFP was detected even stronger in muscle layer when the amount was 50μL. GFP was found in muscle layer when 25μL lentivirus was injected intravenously. GFP was not found in other tissues than in bladder via transurethral perfusion. There was higher GFP in liver, lungs and other organs than in bladder via intravenous injection. Conclusion Lentivirus can mediate GFP transfecting bladder of guinea pig successful?ly and escape the distribution of GFP all over the body intravenously, which will bring new research direction and method for clinical treatment of diseases in bladder.

Objective To observe the clinical effect of electric acupuncture,surrounding acupuncture and cotton moxibustion in the treatment of herpes zoster.Methods Forty cases with herpes zoster were randomly divided into a treatment group and a control group,with 20 patients in each group.The treatment group was treated with electric acupuncture,surrounding acupuncture and cotton moxibustion,while the control group was treated with valaciclovir and vitamin B1.In the two groups severity of pain and the time of pain beginning to ease,pain lasting blisters disappearing,incrustation and decrustation during treatment were observed and recorded,referring to the People's Republic of China Traditional Chinese Medicine Industry Standard(Chinese disease diagnosis and efficacy standard)for efficacy evaluation.Results There was significant difference between the treatment group and the control group with regard to the cure rate(75% versus 35%,P＜0.05);however,the total effective rates of two groups had no significant difference(P＞0.05).After treatment VAS score in treatment group was significantly lower than that in control group(P＜0.05);in treatment group the time of pain beginning to ease and pain lasting were significantly less than those in control group(P＜0.05);the time of blister disappearing in treatment group was significantly faster than that in control group(P＜0.01);the time of incrustation and decrustation in treatment group were significantly less than those in control group(P＜0.05).Conclusion The advantages of electric acupuncture,surrounding acupuncture and cotton moxibustion in the treatment of herpes zoster were shown as faster pain easing,shorter pain lasting,shorter duration of blister and incrustation.This treatment for herpes zoster is safe,effective and affordable.

Blood glucose levels of 220 days were recorded in 85 type 2 diabetic patients for monitoring glycemia for 48-72 h each one by the continuous glucose monitoring system (CGMS). Frequencies of nocturnal hypoglycemia (blood glucose≤2. 8mmol/L) were estimated when bedtime blood glucose levels were≤4.4mmol/ L,≤5.0mmol/L,≤5. 6mmol/L,≤6.1mmol/L,≤6. 7mmol/L, or≤7. 2mmol/L respectively. Nocturnal hypoglycemia occurred in 39 nights of 220 days (17.7%) of 26 patients and their bedtime blood glucose level was (4.4?2.6)mmol/L with a range from 2. 2 to 12. 6 mmol/L. Using a cut-off of bedtime blood glucose at≤6. 7 mmol/L, area under the ROC curve was reached maximal value (0. 359?0. 046). The positive predictive value was 25% and the negative predictive value was 91. 7%. CCMS is a useful tool to detect unaware nocturnal hypoglycemia.

Objective:To isolate genes related to benflumetol resistance in the rodent malaria P.berghei K173 strain.Methods:The mRNA differential display technique was used to identify differentially expressed genes between drug-sensitive P.berghei K173 strain and benflumetol-resistant strain selected under benflumetol pressure.Northern blot was performed in order to determine the genes actually derived from maternal strains.Results:PCR reactions were prepared respectively with twenty-four pairs of primers in each of the strains.Thirty-three differentially displayed genes fragments were cloned and eight of them were sequenced. The eight sequences were novel ESTs and were submitted to GenBank. Homology searching revealed that clone CB52 was slightly homologous to P.falciparum cyclophilin gene. Hybridization confirmed that the gene fragment CB52 was upregulated in the benflumetol-resistant parasite strain, while downregulated in the chloroquine-resistant strain.Conclusions:CB52 fragment was involved in the benflumetol resistance in P.berghei and the genetic mechanisms of drug-resistance to benflumetol and chloroquine were different.

Objective:To compare the effect of age and gender on mastication efficiency between healthy volunteers and dysphagic stroke survivors and to document any correlation of mastication efficiency with mandible movements.Methods:Thirty-two stroke survivors with dysphagia and 84 healthy volunteers were asked to chew two-color gum. Their chewing efficiency was indicated by the degree of color mixing after chewing (SDHue). The SDHue value was evaluated using ViewGum software. The healthy volunteers were further divided into an age 20-40 years group, a 41-60 years group and an over-60 group. The SDHue values were compared among the 3 groups. The SDHue values were correlated with clinical mandibule movement scores.Results:Among the healthy volunteers, those older than 60 years had significantly higher SDHue values on average than those between 20 and 40 years. However, no significant gender difference was observed. The dysphagic stroke survivors had, on average, significantly higher SDHue results than the healthy volunteers, and those results were positively correlated with their mandible movement scores.Conclusions:Mastication efficiency tends to be age-related but not gender-related. Among those with post-stroke dysphagia mandible movement is positively correlated with mastication efficiency.
