Objective Stem cell therapy has been extensively used in clinical practice. However ,the methods available are unable to non‐invasively detect the distribution of cells in vivo. This study was aimed to establish a novel molecular imaging probe for stem cell labeling ,which would monitor cells via fluorescence imaging. Methods 1‐iodododecane was used to modify polyethyleneimine (PEI) to form amphiphilic macromolecules. These macromolecules encapsulated the hydrophobic quantum dots by self‐assembly to form imaging probes. Results Strong fluorescence signals of the probe occurred at 630 nm ,and the probe could be effectively endocyted by mesenchyme stem cells. In vivo imaging showed that significant optic signals occurred in probe‐labeled mesenchyme stem cells compared with the control cells (blank group:1.47e8 [p/s/cm2/sr]/[μW/cm2 ];test group:2.78e8 [p/s/cm2/sr]/[μW/cm2 ]). Conclusion The nanoprobes have good optic imaging effects ,and can be used to la‐bel cells.

OBJECTIVE To investigate different kinds of cefoperazone and sulbactam sodium of different manutactures.METHODS RP-HPLC methods was used to determinate of the concerntrations of 4 categories cefoperazone and sulbactam sodium injections.Agar-dilution method was used to determinate the minimal inhibitory concentration(MIC) of 60 clinical bacterial strains.RESULTS Cefoperazone contents of sample 1 to 4 were 89.11%,100.49%,95.04% and 91.09% respectively;sulbactam contents 90.98%,75.93%,98.98% and 78.09% respectively.The number of the peaks of impurity were 5,4,4,5 respectively;and the total area of impurity peaks were 8.01%,2.94%,2.04% and 10.76%.MIC,MIC50,MIC90 of 4 samples have 2 to 3 difference grades.CONCLUSIONS The products of different manufacturs have different contents and impurities of cefoperazone and sulbactam sodium injections,and the MIC also has different results.In clinical experience,we should surveillance same kinds of antibiotics which produced by different manufacturer and try to reduce the side effect of antibiotics.

Objective To explore the relationships between different marital satisfaction of women with childbearing age and sexual life satisfaction, personality characteristics, coping style and social support. Method-s Three hundred and fifty-one complete cases were randomly obtained by means of ENRICH's marital satisfaction and sexual life satisfaction,EPQ,and etc,and further divided into high marital satisfaction(group A, n=170) and low marital satisfaction(group B, n=181) according to the mean score of the whole sample's macital satisfaction.Then comparisons were carried out between the two groups. Results (1)The means of sexual life satisfaction,Lacores and four indexes of social support in group A were significantly higher than those in group B(P<0.05),but P's and N's scores in group A lower than those in group B (P<0.05). (2) Stepwise multiple regression ana-lyses showed that only sexual life satisfaction (sβ=0.487) and objective social support (sβ=0. 158) entered the equation in whole sample (r=0.290). Conclusion (1) There axe significant differences of sexual life satisfac-tion, personality characteristics and social support among the women with different marital satisfactions. (2)Sexual life satisfaction, personality characteristics and social support are important influencing factors to marital satisfaction among the women.

The aquaporins (AQPs) are small, integral-membrane proteins which selectively transport water across cell plasma membranes. AQPs are over-expressed in tumor cells of different origins, particularly aggressive tumors. AQPs-expressing cancer cells show enhanced migration in vitro and greater local tumor invasion, tumor cell extrava-sations, and metastases in vivo. AQPs inhibition will provide a help for tumor therapy.

Objective To test the efficacy of cognitive behavioral self help therapy for chronic insomnia (CBTI-SH) patients with hypnotic long-term use.Methods A total of 60 adults with chronic insomnia and common comorbidities were recruited.Participants were randomly assigned to either intervention group (IG,n =30) if they had used hypnotics more than 6 months,or control group(CG,n =30) if they had never used hypnotics in the past 6 months.All the patients were given CBTI-SH for 4 weeks.The primary outcome was self-report symptom,based on sleep diaries (including Sleep Latency(SL),Wake after Sleep Onset(WASO),Total Sleep Time(TST),Time In Bed(TIB),Sleep Efficiency(SE) which were evaluated on baseline and at the end of the 2nd,4th week treatment.Continuous variables were evaluated by repeated-measures multivariate analyses of variance (MANOVA).At the conclusion of treatment,each participant was asked how many days per week they enacted each of 6 core elements of the CBT regimen.Linear regression models were examined to determine net predictors of CBTI-SH adherence.Results The MANOVA showed a significant treatment group × time interaction,as well as time main effects for SE,TIB and WASO(P＜0.05).The patients in CG made better improvements than those in IG on SE,TIB and WASO((0.19 ±0.08) vs(0.09 ±0.09),(92.48 ± 32.64) vs (78.06 ±60.05),(103.08 ±64.82) vs (64.92 ±56.36),respectively) (P ＜ 0.05).Effect size were 1.14,0.85 and 0.62 respectively.Self-ratings of treatment adherence showed patients in the IG reported less adherence to standard rise time and TIB prescription than those in CG.(P ＜ 0.05).According to the linear regression models,both age and the comorbidity of chronic somatic diseases explained net associations with CBTI-SH adherence (P ＜ 0.05).Conclusion Chronic insomnia patients with hypnotic long-term use show less sleep improvement and less adherence to CBTI-SH compared with those who don' t use these medicines.Both age and the comorbidity of chronic somatic diseases explain net associations with CBTI-SH adherence.

Objective To research the influences of gambogic acid on rats'cytochrome P450 isoforms by using the Cocktail probe drugs. Methods Rats were randomly divided into several groups. One group of rats received gambogic acid solution containing 0.5 %CMC-Na (2 mg?mL-1,once per day) orally for six days. At the same time,the rats in the other group received 0.5 %CMC-Na solution serving as blank control group. Blood samples were collect at different time point,and the plasma concentration of cocktail probe drugs was determined by HPLC. Results There was insignificant difference of caffeine and dapsone metabolism between the gambogic acid group and the blank group,but the chlorzoxazone was eliminated faster in the gambogic acid group,and the half life of chlozoxazone was shorter. Conclusion Gambogic acid has no significant influence on the cytochrome P450 isoforms of CYP1A2 and CYP3A4,but has an induction on the CYP2E1.

Objective To explore the application of self-made guided wire operating-tray,which is designed for percutaneous tranluminal coronary angioplasty (PTCA),in performing coronary intervention (PCI).Methods A total of 40 patients who were planned to receive PCI were randomly divided into the study group (n=20,using guided wire operating-tray) and the control group (n=20,using traditional method to operate guide wire).Under local anesthesia PCI was carried out in all patients of both groups.The frequency of guide wire winding,the degree of surgical sheet contamination within the operation area,and the comfort and convenience of operating guide wire were assessed,the results were compared between the two groups.Results The frequency of guide wire winding and the degree of surgical sheet contamination within operation area in the study group were remarkably lower than those in the control group (P＜0.05).The comfort and convenience of operating guide wire in the study group was better than that in the control group (P＜0.05).Conclusion In performing PCI,the use of self-made guided wire operating-tray can effectively avoid guide wire winding and reduce the degree of surgical sheet contamination within the operation area.

This paper analysed the rhinoscope's clinical value in microsurgical treatment of intracranial aneurysms. Application of the rhinoscope in 87 patients, only 2 patients had ruptured during operation. However, 11 cases had ruptured in 94 cases without using rhinoscope, P < 0.05, they had a significant difference. By DSA follow-up review, 82 cases of used rhinoscope only 2 cases had remained the aneurysm neck, but 9 cases had the aneurysm neck in 77 cases which had not used the rhinoscope in the microsurgical treatment, P < 0.05, they also had significant difference. The application of rhinoscope in microsurgical treatment of intracranial aneurysms intraoperative, can reduce the risk of the intraoperative aneurysm rupture. It can achieve better clinical effect.
