Objective To develop the Chinese version of the 35-item Medical Outcomes Study HIV Health Survey (MOS-HIV) and to assess the reliability and validity of MOS-HIV among HIV-infected individuals.Methods Between April and July of 2007,a croas-sectional survey of 758 HIV-infected individuals was conducted.Responses to the MOS- HIV were analyzed for its reliability and validity.Results Pearson's correlation coefficients of items for test-retest relia- bility ranged from 0.46-0.92,all internal consistency reliability coefficients exceeded 0.69,and all items were more strongly correlated with hypothesized scale than any other scale.Eight scales of MOS-HIV were significantly associated with CD_4 cell counts.Conclusions The Chinese version of MOS-HIV offers good reliability and validity and can be used as a tool to assess the quality of life of HIV infected individuals in China,thus providing evidence for further studying AIDS related quality of life in this country.

Objective To report the results of balloon catheter dilation in 13 infants with anastomotic stenosis after surgical correction of esophageal atresia. Methods Thirteen cases of anastomotic stenosis after surgical correction of esophageal atresia were enrolled, age ranging from 3 to 10 years. Barium esophagography before balloon dilation showed the diameter of esophageal stenosis ranging 1 to 3 mm and the stenosis was dilated by using balloons of 6 to 12 mm diameter. Results All the 13 cases obtained complete resolution of the stenosis after dilation for twice or thrice. There was no esophageal perforation or other complications with a period of clinical symptomless of 6 to 30 months. Conclusions Ballon catheter dilation is a simple, safe and reliable method for treating anastomotic esophageal stenosis in infants.

Objective To evaluate the role of interventional therapy in Wilm's tumor, renal vascular lesions and ureter stricture in children. Methods Thirty-eight cases were analysed, including 18 cases of Wilm's tumor treated with preprocedural chemotherapy and embolization through renal artery, and 13 cases of unknown-reason hypertension with selective renal arterial angiography for venous blood renin including undergone some patients PTA. Six cases of ureter stricture were dilated with balloon and 1 with hematurea by small aerial embolization. Results After embolization, Wilm's tumors showed reduction in vascularization and reduction in size too. The surrounding tissue of the tumor had a clear demarcation with the normal tissue, decreasing the dissemination to blood and distal metastasis. Renal vascular hypertension was clearly diagnosed and treated, and the increase of renin was helpful to the diagnosis of unknown-reason hypertension. And the obstruction of ureter was improved. Conclusions Interventional therapy is feasible in the application of urinary system diseases with great significance clinically.

Objective To evaluate the application and safety of angiography in infants.Methods Eighteen infants with diagnosis of clinics,CT and MRI as hemangioma, hepatic and renal tumor and cerebral vascular diseases were undertaken digital subtraction angiography(DSA). Results All the cases were found to have anomalous lesions including hemangioma racemosum in 3 cases, capillary hemangioma in 1, hepatoblastoma in 3, renal Wilm's tumor in 1, renal rhabdomyosarcoma in 1, liver arteriovenous fistula (AVF) in 1, Galenic arteriovenous malformation (AVM) in 1,Sturge-Weber Syndrome in 1, AVM OR AVF in the craniofacial region in 2 and pre-operation cerebral angiography of PNET in 2. Conclusions DSA in infants is safe and reliable with extensive clinical application.

Objective To evaluate the efficacy and safety of embolization therapy with NBCA for intracranial arteriovenous fistula (AVF) in infants. Methods Four patients with cerebral arteriovenous fistula were reported, including 3 males and 1 female with nonspecific symptoms and signs, and the diagnosis was made by DSA. Three of them were treated by embolization therapy with NBCA. Results Three of the cases were treated by NBCA, neither death nor complication occurred. Conclusion Intracranial AVF is rare in childhood. Endovascular treatment with NBCA is effective and safe, but the long-term effect has to be comfirmed by follow-up study.

Objective:To investigate the effects of Porhyromonas endodontalis(P.e)liopolysaccharide(LPS)on the expression of IL-23mRNA and protein in mouse osteoblasts MC3T3-E1 and the role of phosphatidylinositol 3-Kinases (PI3K)signaling pathway in this process.Methods:MC3T3-E1 cells were treated with different concentrations of P.e LPS for different hours,or pretreated with LY294002,a special PI3K inhibitor.The IL-23 mRNA and protein expression levels were detected by real-time PCR and Western blot respectively.Results:The level of IL-23 mRNA increased in MC3T3-E1 cells with the increase of concentration and the treatment time of P.e LPS(P <0.05).The IL-23 protein expression was increased by P.e LPS in a time dependent manner(P <0.05).The mRNA and protein of IL-23 decreased(P <0.05)after pretreatment with LY294002.Conclusion:P.e LPS can induce the expression of IL-23 mRNA and protein in MC3T3-E1 cells,and the PI3K signaling pathway may play a part in this process.

With the development of natural products, the research activities on the solubilization methods of water-insoluble natural products have been carried out worldwide. Big molecular weight and poor solubility of most natural active ingredients lead to a very poor oral absorption and low bioavailability, which has extremely limited their development in pharmaceutical fields and clinical application. As a result, it is necessary to find out a suitable technique to improve the solubility and enhance the oral bioavailability of insoluble natural drugs. Based on the related references published in these years, this review introduced some new techniques to improve the solubility and bioavailability of natural drugs, including prodrugs, inclusion complex, solid dispersion, cocrystals, osmotic pump, liquisolid compacts, micronization, self-microemulsifying, nanosuspensions, lipsomes, polymeric micelles and so on, and summarized the theory, characteristics, application range, application examples, problems and development direction of each technique.

OBJECTIVETo explore clinical efficacy of double Endobutto reconstituting coracoclavicular ligament combined with repairing acromioclavicular ligament in stage I in treating acromioclavicular dislocation with Rockwood type III - V .

METHODSFrom January 2010 to September 2013, 56 patients with Rockwood type III - V acromioclavicular dislocation were treated by operation, including 20 males and 36 femlaes, aged from 32 to 52 years old with an average of 38.5 years old. Twenty-five patients were on the left side and 31 cases on the right side. The time from injury to operation was from 3 to 14 days, averaged 7 days. All patients were diagnosed as acromioclavicular dislocation with Rockwood type III - V, and double Endobutto were used to reconstituting coracoclavicular ligament, line metal anchors were applied for repairing acromioclavicular ligament. Postoperative complications were observed, Karlsson and Constant-Murley evaluation standard were used to evaluate clinical effects.

RESULTSAll patients were followed up from 8 to 24 months with average of 11 months. According to Karlsson evaluation standard at 6 months after operation,42 cases were grade A, 13 were grade B and 1 was grade C. Constant-Murley score were improved from (42.80±5.43) before operation to (91.75±4.27) at 6 months after operation. All items at 6 months after operation were better than that of preoperative items. Forty-eight patients got excellent results, 7 were moderate and only 1 with bad result. No shoulder joint adhesion, screw loosening or breakage were occurred during following up.

CONCLUSIONDouble Endobutto reconstituting coracoclavicular ligament combined with repairing acromioclavicular ligament in stage I for the treatment of acromioclavicular dislocation with Rockwood type III - V could obtain early staisfied clinical effects, and benefit for early recovery of shoulder joint function.
