Journal of Clinical Surgery 2015;(2):113-115
Objective To explore the best minimal invasive method in treating renal pelvic stones less than 1.5 cm.Methods A total of 90 patients with renal pelvic stone less than 1.5 cm were enrolled, including 47 cases of retrograde intrarenal surgery(RIRS)by rigid and flexible ureteroscopy with holmium laser lithotripsy,and 43 cases of percutaneous nephrolithotomy(PCNL)by holmium laser lithotripsy.Opera-tion time,stonefree rate(SFR),hospitalization,and complications were analyzed for comparison.Results The average sizes of stone in the RIRS group and PCNL group were 1.2 cm(range 1.0 ~1.5 cm)and 1.3 cm (1.0 ~1.5 cm),respectively.In the RIRS group,45(95.74%)patients out of 47 had complete clearance and 32 patients needed combination of flexible ureteroscopy to fragmentate the stones falling into the renal calices.The operation time was 44 min(range 27 ~70 min)with postoperative fever in 2 cases.The decrea-sing in hemoglobin and hematocrit was(0.18 ±0.06)g/L and 0.11%,respectively.No major complication was recorded.In PCNL group,the mean operation time was 70min(range 45 ~90 min)with a stone-free rate of 95.35%(41 /43).The decreasing in hemoglobin and hematocrit was(17.25 ±6.70)g/L and 5. 62%,respectively.The complications in PCNL group were postoperative fever in two cases and bleeding in two cases.Conclusion RIRS has the advantages of natural orifice endoscopic surgery in shortening opera-tion time,reducing blood transfusion requirements,and decreasing postoperative complications.For renal pelvic stone less than 1.5 cm,RIRS can be the primary choice.

Chinese Journal of Biochemical Pharmaceutics 2014;(2):123-124,127
Objective To investigate the clinical efifcacy of Chinese and western medicine on toxic diffuse goiter (Graves disease) diabetes mellitus. Methods 50 cases of Graves' disease and diabetes mellitus collected in Xianhe hospitol of Dongying city,Shandong Province from June 2010 to June 2011 were randomly divided into observation group(n=25) and control group(n=25). Control group was adopted conventional western medicine treatment. Based on western medicine treatment, observation group was, conducted dialectical types according to TCM theory, and used appropriate Chinese medicine to treatment. Efficacy of two groups after 8 weeks treatment were evaluated. Results The total effective rate in observation group was 90%, higher than 80% in control group(P<0.05). Compared with before treatment, insulin resistance index (HOMA-IR), TT 3, TT 4 levels were signiifcantly decreased, and TSH was signiifcantly increased in both two groups(P<0.01). The improvement of TT 3, TT 4, TSH in treatment group were more obvious than control group, and the difference was signiifcant (P<0.01). Conclusion The combination therapy was effective on patients with Graves' disease and diabetes.
4. Whole genome oligonucleotide microarrays in screening of growth homone adenoma associated genes
Academic Journal of Second Military Medical University 2010;31(10):1109-1113
Objective: To screen for differentially expressed genes associated with the development and progression of human growth hormone adenoma, so as to lay a foundation for future study. Methods: The whole genome oligonucleotide microarray (Affymetrix 133 plus 2.0) was used to examine gene profiles of 8 growth homone adenoma samples and 2 normal pooled pituitary samples. Differentially expressed genes were subjected to bioinformatics analysis. Real-time qPCR was used to verify the microarray result of a randomly selected candidate gene. Results: A total of 187 up-regulated genes and 899 down-regulated genes associated with growth hormone adenoma were screened out, with their functions mainly associated with molecular binding, apoptosis/tumor, metabolism, signal transduction, cell cycle, and transportation activities. Conclusion: Microarray technology can be used for preliminary screen of growth hormone adenoma associated genes. The development and progression of growth homone adenoma are complex processes involving multiple genes, molecules, and pathways.
5. Aquaglyceroporin3-mediated glycerol transport and skin function
Academic Journal of Second Military Medical University 2010;30(12):1416-1419
Aquaglyceroporin3 (AQP3), a dual function water channel, can transport both water molecule and other small molecular substances such as glycerol. AQP3-mediated glycerol transport in skin is very important for skin function, whose absence can lead to dry skin, decreased elasticity, and impaired barrier function, and whose overexpression is related to higher risk of skin tumorigenesis. The multiple roles of AQP3 in skin function make it a potential target in treatment of skin disease and development of cosmetics. This paper reviews the characteristics, function, application, and research perspective of AQP3.

BACKGROUND:Human umbilical cord mesenchymal stem cells are similar to bone marrow mesenchymal stem cells, which can directional y differentiate into neuron-like cells, secrete various cytokines, and provide the base for nerve regeneration. <br> OBJECTIVE:To study the role of chitosan composite nerve conduit carrying umbilical cord mesenchymal stem cells in nerve end-to-side anastomosis. <br> METHODS:Thirty while rabbits were randomized into three groups. The central branch of the right posterior peroneal nerve were cut and proximal y ligated, and then sutured evaginably to the muscle. In the control group, the distal end of the common peroneal nerve were anastomosed into the tibial nerve at 30°-45°;in the stenting group, the chitosan conduit was bridged at the same interval and angle into the end-to-side anastomosis site between the tibial nerve and peroneal nerve;in the cel-stenting group, the chitosan conduit carrying human umbilical cord mesenchymal stem cells was bridged at the same interval and angle into the end-to-side anastomosis site between the tibial nerve and peroneal nerve. After 12 weeks, gross observation, neurophysiological examination and anti-S-100 immunohistochemistry detection were performed. <br> RESULTS AND CONCLUSION:After 12 weeks of operation, in the cel-stenting group, the conduit degraded completely, the nerve diameter was similar to that of the normal peroneal nerve, and the motor nerve conduction velocity was higher than that in the control and stenting groups (P<0.01). Anti-S-100 immunohistochemistry results showed that a great amount of brownish red Schwann cells arranged around the regenerated nerve fibers in the cel-stenting group, while there was few and sparse brownish red substance, and the Schwann cells grew worse in the stenting and control groups. These findings suggest that umbilical cord mesenchymal stem cells have an obvious role in promoting nerve regeneration, induce bud growth, accelerate the growth rate of regenerated fibers, and improve growth and maturity of Schwann cells.

Objective To study the management of enterostomy in children.Methods The clinical data of 425 cases of enterostomy in children were analyzed retrospectively.Results The primary diseases of 425 cases underwent enterostomy included:intestinal perforation(119 cases),intestinal necrosis(36 cases),necrotizing enterocolitis(45 cases),congenital megacolon(61 cases),congenital anal atresia with rectourethral fistula(86 cases),and congenital anal atresia with rectovaginal fistula(78 cases).Among the 425 cases,159 cases underwent small bowel enterostomy and 266 cases had colostomy;single-stoma enterostomy was done in 225 cases,and double-stoma enterostomy in 197 cases.Follow-up was acquired in 389 patients,and all the stomas were closed successfully.The closure time of small bovvel enterostomy was 1-3 month(ayerage 1.87 months)later,and of colostomy was 3-12 month(averag 4.95 months)later.Conclusions When an enterostomy is to be adopted in pediatric surgery,a suitable time and enterostomal location should be chosen according to the state of illness.The timing of enterostomy closure is also very important.
