Objective To determine whether the poking reduction and bone grafting technique with guide through bony tunnel can correct a Hill-Sachs lesion. Methods A total of 30 cadaveric humeri were equally divided into three groups, 10 cadaveric humeri per group. Hill-Sachs lesions were replicated with a osseous defect involving 10% (group A ) , 20% (group B ) and 30% (group C ) of the articular surface. All the bone defects in each group were measured and the poking reduction and bone grafting technique with guide through a bony tunnel was performed in group B and group C. The preoperative and postoperative transverse arc length, longitudinal are length, depth and volume of the osseous defects in group B and group C were compared by using paired t test. Results Before reduction, the transverse arc length of the bone defects was ( 10.9 ± 1.4 )mm in group B and ( 16.3 ± 2.3 ) mm in group C ; longitudinal arc length was ( 22.4 ± 2.4 ) mm in group B and ( 28.0 ± 2.2 ) mm in group C ;depth was (6.9±0.9) mm in group B and (11. 1 ±0.9) mm in group C; volume was (708.7±93.9) mm3 in group B and (1338.3 ± 185.6) mm3 in group C. After reduction, the transverse arc length of the bone defects was (5.1 ± 2.4 ) mm in group B and ( 7.6 ± 3.6 ) mm in group C ; longitudinal arc lengthwas (10.5 ±4.9) mm in group B and (12.3 ±5.3) mm in group C; depth was (0.3±0.1 ) mm in group B and (0.4 ±0.1 ) mm in group C; volume was (48.9 ± 16.1 )mm3 in group B and (70.3 ± 37.9) mm3 in group C. The comparison of all the parameters showed statistical difference (P <0. 01 ). Conclusion The poking reduction and bone grafting technique with guide through a bony tunnel can effectively correct the Hill-Sachs lesions with humeral head osseous defects involving 20% -30% of the articular surface.

Objective To evaluate the therapeutic effect on children with acute idiopathic thrombocytopenic purpura (AITP) by intravenous immunoglobulin (IVIG) or dexmethasone (DEX). Methods Forty-six patients aged from 4 months to 14 years with AITP were randomized to receive IVIG or DEX, and we monitored the platelet count (Tc) and observed the side effects after each treatment. Results There was no difference in the lasting time of Tc≤20×109/L and the time when Tc increased to ≥50×109/L between the treatment of IVIG and DEX (P>0.05). But the percentage of patients with Tc≥50×109/L was higher in the IVIG group Ⅱ (88%) than in the DEX group (50%) after the 5-day treatment (P<0.05). Conclusions We may choose IVIG to treat the patients with AITP complicated by severe mucomenbrane and organ bleeding, while we may use DEX if the patients have no complication.

As a part of the project for the Chinese Pharmacopoeia (2015 edition), the quality standard of Sophora flavescens root extract was investigated and established. According to the methods described in the Appendix of Chinese Pharmacopoeia (2010 edition), the water and ash inspections were carried out. The marker components trifolirhizin, sophoraflavanone G, oxymatrine and oxysophocarpine in the samples were identified by qualitative TLC. The determination of oxymatrine, matrine, oxysophocarpine and sophocarpine was conducted by HPLC and the total flavonoids were measured by ultraviolet spectrophotometry, using sophoraflavanone G as reference substance. The results indicated the spots on the plate were clear with good resolution and the contents of oxymatrine, matrine, oxysophocarpine and sophocarpine in the 13 batches of the samples were 3.87% - 11.1%, 0.970% - 4.33%, 1.30% - 2.59% and 0.260% - 1.14%, respectively. The total flavoids in the 13 batches of the samples were 3.88% - 7.93%. In the study, the validated methods were reproducible and the established quality standard was feasible, which could be used for the quality control of S. flavescens root extract and related preparations.

Objective To investigate the three-dimensional structure of normal male canine prostat- ic duct and acinus system,and to study the mechanism of intraprostatic urinary reflux(IPUR)resulting from high pressure of the posterior urethra by experiment.Methods Using scanning electron microscopy (SEM)and corrosion casting methods,high pressure of the prostatic urethra was produced based upon IPUR in normal male canines.Acrylonitrile-butadiene-styrene(ABS)casting solution was injected into 8 Beagle canines'normal prostates to induce intraprostatie resin solution reflux.Results Six casting molds of nor- real canine prostate specimens were obtained,and the casting failed in 2.By corrosion and casting treatment, the prostate appeared to consist of several glandular lobes.The columnar apophyses of glandular surface were observed.The most glandular ducts pointed outward from urethral peristome.Each glandular duct system was made up of many bifurcated branches from the bough as a duct tree.More than 90% of the bifurcations were Y-shaped,and 6 bifurcated branches were rarely seen.The tip of the duct was vesicular.The diameter and length of the bough were(0.37?0.14)mm and(1.14?0.04)mm,respectively.The intersectional angle of urethra and peripheral glandular duct was the biggest.Peripheral glandular duct was perpendicular or con- verse to urinary flow.Peripheral glandular aeinus appeared elliptic and velvet.The mesh-like and crater-like depressions were shown on the surface of central glandular aeinus.Ejaculatory ducts independently and branchlessly entered the urethra.Conclusions The resin corrosion casting methods combined with SEM can clearly show the three-dimensional structure of normal male canine prostatic duct and acinus system. IPUR may easily occur in the peripheral glands from the morphological view.It is suggested that prostatitis occurs more commonly in peripheral glands,confirming a fact that high pressure of the posterior urethra can induce IPUR.

OBJECTIVETo observe the clinical effects of the no-flip procedure with the Chinese Shang Ring when circumcising adult males with redundant prepuce or phimosis, and to discuss its advantages and disadvantages.
METHODSUsing the no-flip Shang Ring technique, we performed circumcision for 167 adult males aged 18 -72 (mean 27.8) years with redundant prepuce or phimosis, and analyzed the clinical data, including the operation time, postoperative complications, ring-removal time, and postoperative appearance of the penis.
RESULTSComplete follow-up data of 94 cases (56.29%) were obtained. The mean operation time was (5.03 +/- 0.71) minutes and the average ring-removal time was (18.83 +/- 6.70) days. The primary postoperative complications were edema (35 cases [37.23%] at 2 weeks and 9 cases [9.57%] at 4 weeks), including 2 severe cases (2.13%), and infection (3 cases [3.19%]). The pain scores were 2.01 +/- 2.46 during the procedure and 4.52 +/- 2.53 at 24 hours postoperatively. Slipping of the outer ring occurred in 1 case, and delayed removal of the ring in 30 cases (31.91%).
CONCLUSIONAdult male circumcision with the no-flip Shang Ring technique is recommended for its short operation time, simple procedure, fewer postoperative complications, less pain, and better incision appearance.

OBJECTIVETo study the impact of the chloride channel dysfunction of the cystic fibrosis transmembrane conductance regulator (CFTR) on the cytoskeleton of Sertoli cells in the mouse.
METHODSTM4 Sertoli cells were cultured and treated with CFTR(inh)-172 at the concentrations of 1, 5, 10 and 20 μmol/L for 48 hours. Then the cytotoxicity of CFT(inh)-172 was assessed by CCK-8 assay, the expressions of F-actin and Ac-tub in the TM4 Sertoli cells detected by immunofluorescence assay, and those of N-cadherin, vimentin and vinculin determined by qPCR.
RESULTSCFTR(inh)-172 produced cytotoxicity to the TM4 Sertoli cells at the concentration of 20 μmol/L. The expressions of F-actin and Ac-tub were decreased gradually in the TM4 Sertoli cells with the prolonging of treatment time and increasing concentration of CFTR(inh)-172 (P < 0.05). The results of qPCR showed that different concentrations of CFTR(inh)-172 worked no significant influence on the mRNA expressions of N-cadherin, vimentin and vinculin in the Sertoli cells.
CONCLUSIONThe CFTR chloride channel plays an important role in maintaining the normal cytoskeleton of Sertoli cells. The reduced function and expression of the CFTR chloride channel may affect the function of Sertoli cells and consequently spermatogenesis of the testis.
