Objective To discuss the efficacy of the flexible ureteroscopy combined with Holmium laser lithotripsy for kidney calculi with HIV positive patients.Methods From May 2015 to May 2016,47 cases of patients with renal calculi were treated by the flexible ureteroscopy combined with Holmium laser lithotripsy in our hospital.There were 29 cases male,18 cases female,aged from 22 to 56 years old,average 39 years.There were 38 cases with single stone,9 cases with multiple stones.There were 9 cases with stones on both sides.Flexible ureteroscopy channel sheath was used in surgery.Stones were fragmented by Holmium laser.During one-month follow-up after surgery,stone removal and stone free rate were recorded.Residual stones were re-treated with a secondary lithotripsy or ESWL.Results The flexible ureteroscopy channel sheath was indwelled successfully in all the cases.All stones were detected.The average operation time was 63min (range,42-141min) and the median postoperative stay was 4.5days (range,2-16 d).Among the 47 patients,41 patients underwent first-stage lithotripsy,6 patients underwent second-stage ESWL after lithotripsy,and 1 patient underwent third-stage lithotripsy.The one-month stone free rate was 87.2％ (41/47).The total stone free rate was 97.9％ (46/47) after second-stage lithotripsy.Postoperative fever occurred in 4 cases after lithotripsy.No blood transfusion,systemic infection,ureteral perforation,or ureteral avulsion occurred.The total complication rate was 8.5％ (4/47).The mean number of CD4 +T lymphocytes before lithotripsy was 402/μl,and was 410/μl 3 days after lithotripsy.There was no Statistical differences between them.Conclusions Flexible ureteroscopy combined Holmium laserlithotripsy could be a safe and effective treatment for kidney calculi patients with HIV/AIDS positive.

Objective To investigate the effect of Yiqi Huoxue Huatan Decoction(YHHD) on gene expression of vascular endothelial growth factor(VEGF), intercellular adhesion molecule 1(ICAM-1) in the colonic mucosa of ulcerative colitis rats. Methods Sixty rats were divided into six groups, namely normal control group, model control group, low-, middle- and high-dose Y HHD group(gastric gavage of YHHD in the dosage of 13, 26, 52 g·kg-1·d-1 respectively) , and Mesalazine(0.5 g·kg-1·d-1 ) group. T he rat model of ulcerative colitis was established by enema with 2, 4, 6-trinitrobenzene sulfonic acid(TNBS)mixture(2.5%TNBS and 50% ethanol). The changes in rat body weight were monitored. After treatment, pathological features of the colonic mucosa were observed under light microscope, and VEGF and ICAM-1 gene expression levels in the colonic mucosa were measured by reverse t ranscripti on polymerase chai n reaction(RT-PCR). Results Body weight was lighter, and relative gene expression levels of VEGF and ICAM-1 in the model group were significantly higher than those in the normal control group, and pathological features of the colonic mucosa was obvious, the differences being significant between the two groups(P<0.01). Compared with the model group, body weight was increased , pathological features of the colonic mucosa were relieved, and relative gene expression levels of VEGF and ICAM-1 were significantly decreased in YHHD groups(P<0.01), and high-dose YHHD showed the strongest effect. Conclusion YHHD can down-regulate the gene expression of VEGF and ICAM-1, which may be one of its therapeutic mechanisms for ulcerative colitis.

Objective To analyze the VP1-VP4 genetic region of enterovirus 71 ( EV71 ) strains isolated from children with severe or mild hand, foot and mouth disease ( HFMD) in Shenzhen in 2012. Methods EV71 strains were isolated from five children with mild HFMD and five children with severe HFMD in Shenzhen in 2012.Reverse transcription-polymerase chain reaction ( RT-PCR) method was used to amplify the sequence of VP1-VP4 genes of EV71 strains.The sequences of the amplified products were analyzed by comparing with those of the EV71 reference strains ( A, B and C genotypes) published in Gen-Bank using nucleotide alignment, amino acid alignment and phylogenetic tree analysis.Results The homo-geneity between the EV71 strains isolated from severe and mild cases was 95.1%-98.2% in nucleotides and 99.2%-100% in amino acids.The VP1-VP4 nucleotide sequences of 5 strains isolated from severe cases and 5 strains from mild cases in Shenzhen shared 87.9%-97.8% homologies in nucleotides and 97.3%-99.9% homologies in amino acids with the genotype C EV71 reference strain.The EV71 strains isolated from children in Shenzhen were highly similar with the EV71 strain (FJ439769) isolated in Fuyang in 2008 and the one isolated in Jingdezhen in 2011 (JQ806378, C4a subtype) in nucleotide sequences.Mutations at the residue 31 in the VP1 region ( N→D ) were detected in 3 strains isolated from children with severe HFMD.Conclusion All of the 10 EV71 strains isolated in Shenzhen in 2012 belonged to the sub-genotype C4a.The mutation ( aa31 N→D) in the VP1 region of EV71 might be related to the different clinical mani-festations of HFMD cases in Shenzhen area.
