ABSTRACT
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.
ABSTRACT
Objective: To demonstrate that expression of the CCRSDelta32 protein in PBMCs able to down-regulate surface expression of the HIV-1 coreceptor CCR5 and CXCR4.Methods:CCR5Delta32 gene was amplified from human peripheral blood mononuclear cells(PBMCs)genomic DNA by using PCR, and then cloned into lentiviral vector pLenti6/V5-D-TOPO.Recombinant lentiviral particles were produced by packaging using 293T cells.Human PBMCs were transfected with the constructed recombinant lentiviral particles and the expression of CCR5Delta32 was detected by Western blot.The level of CCR5 and CXCR4 expression on transfected PBMCs was detected by FACS analysis.Results: The recombinant lentiviral vector pLenti-CCR5Delta32 was constructed successfully, and the target protein was expressed in PBMCs.FACS analysis showed that CCR5Delta32 protein expressed in PBMCs was able to down-regulate cell surface expression of CCR5 and CXCR4.Conclusion: This study is expected to be used for the gene therapy on AIDS, which deserves further study.
ABSTRACT
Objective To study the clinical characteristic of acquired immune deficiency syndrome (AIDS) patients younger than 15 years old and to explore the influence of human immunodeficiency virus (HIV) infection on them. Methods The clinical information, including demographic profile, clinical stages of the disease, laboratory test results and developmental status were gathered from 275 antiretroviral therapy naive patients. Results Seventy eight point nine percent patients were infected by vertical transmission. Sixteen percent were infected by receiving blood products. The average age was (7.6±3. 7) years, with 5 cases younger than 1 year old, 104 cases ranging from 1 - 5 years and 166 cases elder than 6 years. Seventy point one percent patients were classified as stage 3 or 4 according to World Health Organization definitions. The average CD4 count was ( 137 ± 159 )/μL, ( 304 ± 317 ) /μL and ( 1 246 ± 776 )/μL respectively in children elder than 6 years, ranging from 1 to 5 years and younger than 1 year. One hundred and eighty one cases suffered from anemia on different severity grading. The most common HIV related symdromes included persistent fever, skin damage, persistent diarrhea, oral candidiasis and recurrent upper respiratory tract infection. Among these infected children, 49. 6% showed height lower than x - 2s and 19. 9% showed weight lower than x - 2s. Conclusions Most survival pediatric AIDS patients are elder than 6 years. HIV infection can significantly affect the children's immune system function,growth and development.
