Objective To investigate the effect of salidroside on brain edema and neurological function in global cerebral ischemia-reperfusion injury in rats.Methods A total of 100 Sprague Dawley rats were randomly divided into sham operation,ischemia-reperfusion and salidroside 12,24 and 48 mg/kg groups (n =20 in each group),and than redivided into 6 h,24 h,72 h and 7 dsubgroups (n =5 in each subgroup).A rat model of global cerebral ischemia was established using the four-vessel occlusion method.Immediately after modeling,all groups were administered intragastrically for 7 days.The brain water content was quantitated by the wet-dry weight method.The neurological evaluation was performed using a neurological deficit score (NDS).Results After modeling both the ischemia-reperfusion group and all the salidroside groups had significant neurological deficit,and as time went by,it was improved gradually.Compared to the ischemia-reperfusion group at the corresponding time points,neurological deficit in all the salidroside groups was improved significantly (all P < 0.05),and showing a dose-dependent trend.Compared to the salidroside 12 mg/kg and 24 mg/kg groups,neurological deficit in the salidroside 48 mg/kg group was improved significantly at 72 hours and 7 days (all P < 0.05).The brain water contents began to increase at 6 hours after modeling in the the ischemia-reperfusion group and all the salidroside group.They reached the peak at 72 hours,and significantly higher than that in the sham operation group (all P < 0.05).The brain water contents in all the salidroside group were significantly lower than those in the ischemiareperfusion group at 24 and 72 hours after modeling (all P < 0.05) and showing a dosedependent trend.The brain water content in the salidroside 48 mg/kg group was close to that in the sham operation group at 7 days after modeling.Conclusions Salidroside may significantlydecrease brain edema and improve neurological function in global cerebral ischemia-reperfusion injury in rats,and it has a neuroprotective effect.

Objective This objective of the study was to analyze the factors related to being recaptured and condom use among low-fee female sex workers (FSWs) to provide reference in developing human immunodeficiency virus (HIV) intervention strategy. Methods Physical examination certificates were designed by Zhongshan County Center for Disease Control and Prevention to record HIV and syphilis test results for low-fee FSWs from 2013 to 2015. Low-fee FSWs were asked to show physical examination certificates in the next intervention and test. Multivariate Logistic regression was used to analyze factors associated with being captured with physical examination certificates. Generalized linear mixed model was used to analyze factors associated with condom use with clients. Results A total of 220 low-fee FSWs were recruited by using physical examination certificates and received 389 interviews from 2013 to 2015. The proportions of HIV positive and syphilis positive were 4.2% (9/213) and 30.0% (64/213) respectively among those who had HIV and syphilis test. Results of multivariate Logistic regression analysis showed that low-fee FSWs who had been FSWs for more than 4 years (OR=2.95, 95% CI:1.35-6.45), and worked in the local county in the past 30 days (OR=11.74, 95% CI: 5.26-26.20), were more likely to be captured with physical examination certificates. Results of generalized linear mixed model showed that those who were captured at least once (OR=3.33, 95% CI: 1.34-8.27), had junior middle school education and above (OR=22.79, 95% CI: 3.75-138.57), had high HIV knowledge (OR=3.57, 95% CI: 1.52-8.38), and charged more than 30 yuan for vaginal sex (OR=30.68, 95% CI: 12.57-74.90), were more likely to use condom consistently. Conclusions Physical examination certificates could be used for low-fee FSWs surveillance and intervention and tracking their HIV and syphilis status. The intervention strategy should take these into consideration.

Objective To observe the effects of fennel essential oil and water extracts (distilled oil is not included) on gastrointestinal motility disorder caused by atropine in mice.Methods Kunming mice were randomly divided into blank control group, model group atropine, water extracts group, fennel essential oil group, mosapride group. Blank control group and model group atropine were orally administered with normal saline of 0.2 ml/10 g. Water extracts group was orally administered with Water extracts (75 mg/ml) of 0.2 ml/10 g. Fennel essential oil group was orally administered with Essential oil of 300 mg/kg. Mosapride group was orally administered with mosapride(15 mg/ml). Subjects were orally treated for 3 d. After fasting for 18 h, blank control group was intraperitoneally injected saline on the fourth day, and other groups were injected atropine sulfate injection to induce animal model of gastrointestinal motility disorder. Blue dextran(BD)2000 was used to observe the gastric emptying rate and rate of intestinal propulsion. Results Gastric emptying rates of fennel essential oil group, mosapride group, water extracts group and model group atropine were respectively(91.97±4.42)%, (90.26±5.81)%, (80.01±6.27)%,(72.88±9.13)%,and intestinal pushing rates were respectively(53.32±7.49)%,(53.02±9.13)%,(44.16±7.68)%,(37.52±6.19)%.Fennel essential oil, mosapride and water extracts enhanced the gastric emptying and intestinal propulsion in gastrointestinal motility disorder animal caused by atropine(P values were 0.004、0.001、0.004、0.003、0.025、0.015),where Fennel essential oil and mosapride were superior to the water,extracts(P values were 0.000、0.002、0.001、0.001).Conclusion Fennel extracts may promote gastrointestinal movement of atropine-induced gastrointestinal motility disorder in mice and fennel essential oil is the main active ingredient.

Objective To investigate the effects of radicular dentin treatments of sodium hypochlorite (NaOCl) and ethylenediaminetctraacetic acid (EDTA) on the regional root canal bending interface of quartz fiber posts using 2 luting materials with SEM analysis. Methods Nine intact maxillary central incisors were sectioned and endodontically treated. Standardized post space preparations and acid etch were performed . All specimens were randomly divided into 3 groups(n =3). D.T. LIGHT posts were placed into the root canal using one of three radicular dentin treatments(0. 9% NaCl for 60 s, 10% NaOCl for60 s, 17% EDTA for 60 s followed by 5.25% NaOCl for 60 s) in combination of one of two luting materials (DuoLink, LuxaCore) respectively (factorial design). Cervical, middle, apical sections of each teeth are used for SEM study and spectroscopy of dispersion energy (EDS) microanalysis. Results With the radicular dentin treatment with 10% NaOCl alone or with 17% EDTA followed by 5.25% NaOCl, longer and increased number of penetration of resin tags into the dentinal tubules were observed at the resin-dentin interfaces, and adhesive lateral branches could be found easily. EDS microanalysis showed increase in the infiltration behavior of the luting cement. Conclusions Radicular dentin treatments provide good resin infiltration, which can produce a three-dimensional interlocking micronetwork of resin tags in the dentin tubules with multiple lateral branches that penetrate the intertubalar dentin, thus positively influence the adhesion between dentin and the luting materials.

OBJECTIVE:
To detect the correlation between survivin and rheumatoid arthritis (RA) to determine the possible mechanism of RA and multidrug resistance in refractory rheumatoid arthritis (RRA).
METHODS:
We collected 15 normal controls, 35 early untreated RA patients, 20 effectively treated RA patients and 25 RRA patients according to selection standard. The expression of survivin in the peripheral blood lymphocytes was detected by immunocytochemical method.
RESULTS:
There was significant difference in the survivin expression in the peripheral blood lymphocytes between the early untreated and normal control group (χ(2)=29.59, P<0.01). The survivin expression in the peripheral blood lymphocytes of effectively treated RA group slightly elevated, but had no significant difference with the normal control group (χ(2)=1.591, P>0.05). The survivin expression in the peripheral blood lymphocytes of the RRA group was significantly stronger than in the effectively treated RA group (χ(2)=24.35, P<0.01), and normal control group (χ(2)=26.53, P<0.01), with no significant difference compared with early untreated group (χ(2)=0.014,P>0.05).
CONCLUSION
Survivin has an influential role in the occurrence and development of rheumatism arthritis. Survivin might be involved in refractory multidrug resistance of RA and be one of the multidrug resistance mechanism of RRA.
