OBJECTIVETo improve the methods and reduce the complications of circumcision with a disposable suture device.

METHODSThis study included 325 male patients aged 14-65 (mean 28.9) years, treated for redundant prepuce or phimosis by modified (n = 201) or conventional circumcision with a disposable suture device (n = 124). We compared the incidence of complications and the patients' satisfaction between the two surgical methods.

RESULTSCompared with conventional circumcision, the modified method showed a significantly lower incidence of postoperative bleeding (14.52% vs 2.49% , P < 0.05) and a lower rate of second surgery for penile hematoma (4.03% vs 0.50%, P < 0.05). The patients' satisfaction was markedly higher with the modified method (91.94%) than with conventional circumcision (97.51%) (P < 0.05).

CONCLUSIONModified circumcision with the disposable suture device can significantly reduce the incidence of postoperative bleeding and penile hematoma and therefore deserves wide clinical application.

The present study was aimed to explore the relationship of transforming growth factor (TGF) beta3 gene SfaNI polymorphism (rs3917201 locus) and non-syndromic cleft lip with or without cleft palate (NSCL/P) in people of the Uygur's Nationality and Han's in Xinjiang, China. TGFbeta3 gene fragment including SfaNI was amplified and purified as the template of the primer extension reaction thenafter. The single base extension reaction was carried out u sing SNP specific extension primer. The products were purified and analyzed by MALDI-TOF. The test showed that there were not significantly different frequencies of AA, AG, GG genotypes and alleles between the whole NSCL/P group and the whole control group (P > 0.05). Within the Uygurs or Hans, the frequencies of genotypes between the whole NSCL/P group and the whole control group were not significantly different (P > 0.05). The distributions of the A, G alleles between the NSCL/P group and the control group were not significantly different within the Uygurs (P > 0.05), but significant different within the Hans (P < 0.05). In all the NSCL/P patients, frequencies of genotypes and alleles were not significantly different between Uygurs and Hans (P > 0.05), and not significantly different (P > 0.05) either between Uygurs and Hans in all the healthy persons. The results proved that TGFbeta3 gene SfaNI polymorphism may not be related to NSCL/P in Xinjiang Uygur people, while the occurrence of NSCL/P in Han population may be related to frequency of the A and G allele of SfaNI polymorphism.

OBJECTIVETo investigate molding technology of total alkaloids from Sophora alopecuroides freeze-dried powders and observe its inhibition effects on liver transplantation tumor in mice.

METHODWith color, clarity, water-soluble and formability as indexes, single factor tests were adopted to screen type and amount of filler, the concentration of total alkaloids in drug liquid, pH in order to determine optimum prescription of total alkaloids from S. alopecuroides freeze-dried powders, the lowest melting point was determined and freeze drying curve was drafted. Mice hepatoma H22 ascites tumor strain was sterile inoculated in right axillary subcutaneous of mice, and antitumor effect of total alkaloids from S. alopecuroides freeze-dried powders on liver transplantation tumor H22 in mice.

RESULTWhen selected 80 g x L(-1) as mannitol as filler, the concentration of total alkaloids in drug liquid was 25 g x L(-1) and pH 6.5-7.5, freeze-dried effect was optimum with fast reconstitute speed. Average inhibition rate of the big (120 mg x kg(-1)) and medium (60 mg x kg(-1)) dose group of total alkaloids from S. alopecuroides freeze-dried powders on liver transplantation tumor H22 in mice were 56.08% and 35.49%, respectively.

CONCLUSIONPreparation technology was reasonable, reproducible and stable, total alkaloids from S. alopecuroides freeze-dried powders had significant antitumor effect and showed a dose-effect relationship.

As the neuron-specific actin binding protein,Drebrin ( developmentally regulated brain protein) can affect spiny and synaptic morphology and function by changing the property of cytoskeleton,and modulate synaptic plasticity. Neural excitability regulates expression and activitiy of Drebrin through a variety of signaling molecules,making Drebrin' s function correlated with that of neurons. Under pathological conditions,the abnormal Drebrin affects synaptic plasticity,which leads to different degrees of cognitive dysfunction,and it is closely relates to the progress of cognitive dysfunction. Extensive studies of physiological and pathological functions of Drebrin in overall and molecular ways will not only contribute to a thorough understanding of cognitive dysfunction,but also develop the new target of therapeutics for cognitive dysfunction.

Objective To detect the osteopontin(OPN)expression in renal tissue of rats with fluorosis and low calcium diet,and study the role of OPN in renal injury of fluorosis.Methods Forty-eight aged 1 month Wistar rats,80-120 g,were randomly divided into 4 groups by 2×2 factorial design(the number of female and male in each group was equal):the control group,high-flluoride group,low-calcium group and low-calcium with high-fluoride group.All rats of the fluorosis groups were fed with feed containing corn exposed to coal-burning from endemic fluorosis areas with high fluoride(100 mg/kg,corn),the other two groups were fed with feed containing coru from nonendemic fluorosis areas(fluoride 5 mg/kg,corn).After 16 weeks,the rats were killed.The change of teeth was examined,and the incidence rate of dental fluorosis was calculated.The expressions of both protein and mRNA of OPN in rat renal tissue were determined by RT-PCR and immunohistochemistry after four-month experimentation.Results The growth of teeth was very well in the control group and the low-calcium group.The two high-fluoride groups showed evident dental fluorosis(100%).The results of immunohistochemistry showed that the OPN protein was localized in renal tubule cytoplasm.The OPN-positive cells from renal tissue were lightly and scatteredly stained in control and low-calcium groups.The OPN-positive cells had deeper color in high-fluoride group and low-calcium with high-fluoride group,widely distributed in the renal tubular epithelial cells.The protein expression of OPN in the two groups exposed to fluoride(168.64±13.21,169.26±8.92)was significantly higher than those of the corresponding control group(145.78±10.26,all P<0.01)and low-calcium group(149.60±16.84,all P<0.01).The mRNA expression of OPN in the two groups exposed to fluoride(1.89±0.37,1.94±0.22)was significantly higher than those of the corresponding control group(1.32±0.26,all P<0.05)and low-calcium group(1.30±0.186,P<0.05),respectively.High fluoride influenced the expression of protein and mRNA of OPN(F=13.821,4.24,all P<0.05).Low calcium did not affect the expression of protein and mRNA of OPN(F=2.164,0.58,all P>0.05).However,high fluoride and low calcium had a cross interaction on the expression of protein and mRNA of OPN(F=6.257,432,all P<0.05).Conclusions Over-dose fluoride enhances the expression of OPN.The higher expression observed in the cases exposed to high fluoride concentration is associated with serious renal injury.OPN may he a potential marker for renal injury in fluorosis.Moreover,over-dose fluoride and low calcium make the renal injury worse,indicating low calcium plays an important part in renal injury by fluoride.

AIM: To evaluate the protective effects of mycophenolate mofetil on the kidneys of type 2 diabetic rats and discover their mechanisms. METHODS: Wistar rats were divided into three groups, such as normal control rats, diabetic rats, and diabetic rats in the treatment with mycophenolate mofetil (MMF, 15 mg?kg -1 ?d -1 ). Thirteen weeks later, urinary albumin excretory rate (UAE), creatine clearance (Ccr), blood glucose, blood insulin and blood lipid were measured, and kidney pathology was observed. Inmmunohistochemistry was used to analyze the expression of CTGF, ColI and ColⅢ. RESULTS: Mycophenolate mofetil decreased UAE, Ccr and reduced glomerular volume. The expression of CTGF and deposition of ECM decreased after diabetic rats received mycophenolate mofetil. CONCLUSION: Mycophenolate mofetil can protect the kidney of diabetic rats. Its mechanism may be related to the decrease of CTGF expression and extracellular matrix deposition in renal tissue.
