Objective To compare the clinical efficacies between warm needling and Ibuprofen sustained release capsules (a nonsteroidal anti-inflammatory drug, NSAID) in treating patients with dysmenorrhea in adenomyosis. MethodSixty-five patients with dysmenorrhea induced by adenomyosis were randomized into a treatment group of 33 cases and a control group of 32 cases. The control group was intervened by oral administration of Ibuprofen sustained release capsules, while the treatment group was intervened by warm needling.The intervention lasted 3 menstrual cycles and a 3-month follow-up was studied. The Visual Analogue Scale (VAS), dysmenorrhea symptoms scores and clinical efficacy were compared between the two groups.ResultThe VAS scores after the intervention and inthe first and second months of the follow-up study were significantly different from the pre-treatment score in the two groups (P<0.01); the VAS score of the 3-month follow-up was significantly different from the score before the intervention in the treatment group (P<0.01). There were significant differences in comparing the VAS score after the intervention and in the follow-up study between the two groups (P<0.01), and the treatment group was superior to the control group. The dysmenorrhea symptoms scoresdeclined significantly after the intervention and in the first and second months of the follow-up study in both groups (P<0.01); the dysmenorrhea symptoms score of the 3-month follow-up study decreased in the treatment group and was significantly different from the pre-treatment score (P<0.01). There were significant differences in comparing the dysmenorrhea symptoms scores in the second and third months of the follow-up study between the two groups (P<0.01). The total effective rate was 93.9% in the treatment group, significantly better than 62.5% in the control group (P<0.01).ConclusionWarm needling is effective in easing pain and improving the symptoms of dysmenorrhea in adenomyosis, and can produce a consistent efficacy after the termination of thetreatment; it's superior to NSAIDs in comparing both short-term and long-term treatment efficacies.

Objective To establish loop-mediated isothermal amplification(LAMP)method for detecting Streptococcus pneumoniae in clinical samples.Methods Four Streptococcus pneumoniae-specific LAMP primers were designed according to the published sequence of strain R6(GenBank accession number AE008540).Genomie DNA in positive blood cultures was extracted by nanidine hydrochloride and benzene-methanol.Then lytA was amplified by LAMP at 63℃ for 45 minutes.We observed the turbidity in thereaction tube.For further confirmation.The amplified products were also detected using electrophoresis in 2% agarose gels,followed by ethidium bromide staining.Resuits 16 strains of Streptococcus pneumoniae were detected in 196 positive blood cuhure bottles by LAMP.Compared with traditional method.It8 sensitivity and specificity were both 100%and the detection could be finished in an hour.The assay had a minimum detection limit of 102 CFU/m1.Conclusions This IJAMP-based assay is simple,rapid.Sensitive and specific.It can be used to detect trept OCOCCUS pneumoniae in clinical samples.

Objective To investigate the role of osteopontin (OPN) in cholesterol gallstone formation.MethodsGallbladder bile was obtained from patients with cholelithiasis (n=36,the experimental group) and from donors of liver transplantation (n=19,the control group).OPN,calcium ion and lipid were analysed quantitively.The nucleating role of OPN in bile was evaluated using nucleating time (NT) approach.ResultsOPN inhibited cholesterol nucleation in a dose dependent manner.OPN (50 μg/ml and 100 μg/ml) prolonged NT by 48.90％ (91.51％) and 17.07％ (32.93％) in lithogenic and control bile,respectively.OPN (100 μg/ml) also inhibited the nucleating effect induced by calcium ion.Furthermore,a combination of OPN (50 μg/ml) and calcium prolonged NT by 75.78％ and 33.96％ in lithogenic and control bile,respectively.A combination of OPN (100 μg/ml) and calcium prolonged NT by 125.9％ and 62.26％ in the 2 groups.The contents of osteopontin and calcium were significantly lower in lithogenic bile than control bile (P＜0.05).On the other hand,the cholesterol saturation index and the contents of cholesterol,phospholipid and bile acid were significantly higher (P＜0.05).ConclusionsOPN inhibited cholesterol gallstone formation.It may be involved in the pathogenesis of cholelithiasis.

Investigation of the pharmacokinetics of paeonol microemulsion, microemulsion-based gels and marketed paeonol ointments by the skin-blood synchronous microdialysis coupled with LC/MS is reported in this study. The microdialysis systems were established by linear probes and concentric circles probes. In vivo recovery of paeonol in skin is (69.7 +/- 4.8) % and in blood is (51.6 +/- 7.2)%. The paeonol microemulsion, microemulsion-based gels and marketed paeonol ointments were administered to rats. PBS (pH 7.4) served as perfused solution. The perfusion rate was 5 microL x mL(-1) and the microdialysis samples were collected every 20 min intervals. The paeonol concentration in perfused solution was determined by LC/MS. The results showed that paeonol microemulsion and microemulsion-based gels significantly raised the drug concentrations in skin more than that of paeonol ointments. The paeonol microemulsion-based gels has similar bioavailability as the paeonol ointments in blood, but its blood drug concentrations were steadier. The paeonol microemulsion-based gels may be developed into a new preparation for dermis eczema. The skin-blood synchronous microdialysis technique proved to be a new method for the pharmacokinetics study of transdermal delivery systems.

Objective To investigate the role of osteopontin (OPN) in the pathogenesis ot cholesterol gallstone formation in bile.Methods The nucleation time of OPN in model bile and human gallbladder bile was studied by the nucleation time assay,the effect of OPN on cholesterol crystal growth in model bile was examined by the cholesterol crystal growth assay.The effect of OPN on vesicle was detected by the transmission electron microscopy in model bile and gallbladder bile; then the content of OPN and calcium were detected via the commercial kits in human bile.Results Osteopontin prolonged nucleation time in a dose dependent manner in model bile and human bile,and this effect was correlated with calcium.Compared with control group,the nucleation times were prolonged by 1.50and 1.93 times in lithogenic bile at the concentration of osteopontin 50 μg/ml and 100 μg/ml (P＜0.01),respectively. Nucleation time were prolonged by 1.17 and 1.33 times in normal bile (P＜0.01) and by 1.29 and 1.48 times in model bile (P＜0.01),respectively.The rate of cholesterol crystals growth was not influenced by calcium ions,but inhibited by osteopontin in a dose dependent manner in the model bile.Furthermore,the formation,aggregation and fusion of vesicles were delayed by osteopontin in bile samples as indicated by the transmission electron microscopy.The concentration of osteopontin [(0.53± 0.08) mg/ml vs. (0.65 ± 0.14) mg/ml,P＜0.05] and the calcium ions [ (0.71 ± 0.17) mmol/L vs. ( 0.84 ± 0.08 ) mmol/L,P ＜ 0.05 ] were lower in lithogenic bile than in control.Conclusions Osteopontin can inhibit the cholesterol gallstone formation in model and human gallbladder bile as the anti nucleating factor.
