Postoperative bleeding was noted in 8 cases (13.3%) at the 1 st and 7 th day after operation, which was cured by conservative methods. 24 patients had no annal spasm following the procedure. Follow-up period lasting for 1-7 months showed no complications Conclusions PPH is a safe and effective treatment for hemorrhoids at the third or fourth degree with the advantages of shorter hsopitaliztion time and quicker recovery.

In order to evaluate the accuracy of RayPex5 apex locator in measuring root canal working length in clinical practice and to analyze the possible factor resulting in deviation, the working length of total 211 root canals were measured by handing method and electronic method respectively. The exact working length of those root canals were determined by X-ray method. The accuracy rate of electronic method and handing method was 96.21% and 78.2% respectively, with significant difference(P<0.001). The accuracy rate of front teeth group and molar group measured by electronic method was 100% and 92.5% respectively, with significant difference(P<0.05), while the apical paradentitis group and the apical non-paradentitis group, the front teeth group and the premolar group, and the premolar group and the molar group didn' t differ from each other, respectively. The study showed that the accuracy rate of electronic method was high for determining root canal working length, and Raypex 5 apex locator could define apical seat to measure root canal working length accurately.

Objective To investigate the clinicopathologic features and the expression of p53,PCNA and Bcl-2in tricholemmal carcinoma.Methods Skin lesions were studied with HE staining and immunohis-tochemical markers for p53,PCNA and Bcl-2(S-P method)in22cases of skin tricholemmal carcinoma.Both morphological manifestations and immunohistochemical expression were observed.Results There were15fe-male and7male cases of tricholemmal carcinoma with the ages of40-79y,including16cases whose scalp were involved.Positive staining of p53,PCNA and Bcl-2was found in72%,100%and63%of patients,re-spectively.The positive cells of p53were diffusely distributed.PCNA-positive cells were increased along with the degree of differentiation.Significant differences of Bcl-2expression were found among the various degrees of differentiation(P

Objective To study the effect of renal p53 protein expression on kidney development in rats with intrauterine growth restriction ( IUGR) . Methods Pregnant rats were randomly assigned into normal group, IUGR group and L-Arg treated group. Normal group were fed with normal diet (21％protein). IUGR group and L-Arg treated group were fed with low-protein diet (10％ protein). During lactation, maternal rats in the three groups were all fed with normal diet. Maternal rats in L-Arg treated group were given additional special drinking water ( L-Arg:200 mg/kg) , while maternal rats in normal and IUGR group were given normal drinking water. Offspring weaned after 21 d and had free access to normal rodent diet and water. When the pups grew up to 2 m, the number of glomeruli was counted using acid digestion method, the proliferation and apoptosis of glomerular and tubular cells were studied using TUNEL and Ki-67 immunohistochemistry, and the ultrastructure of epithelial cells was determined by electron microscopy. At 7 d, 21 d, 2 m and 3 m, p53 protein expression in renal tissue was measured by Western blot, respectively. Results At 2 m, the number of glomerulus ( right kidney) in IUGR group was significantly lower than normal group [(23 647±541) vs. (27 689±492), P＜0. 01]; the index of renal cell apoptosis in IUGR group was higher than normal group [(21. 9 ± 2. 0) vs. (16. 7 ± 2. 5), P＜0. 05];however, IUGR group and normal group had no statistically significant difference (P＞0. 05). The proliferation of mesangial cells was found in IUGR and L-Arg treated group, but not in normal group. And the extent of proliferation in L-Arg treated group was lesser than IUGR group. A reduction of foot process and partial fusion of foot process could be observed in IUGR group and L-Arg treated group while the foot process morphology in normal group was normal. At 2 m and 3 m, p53 protein level in IUGR group and L-Arg treated group were higher than normal group [ 2 m: ( 0. 28 ± 0. 03 ) and ( 0. 21 ± 0. 01 ) vs. (0. 10±0. 02);3 m:(0. 39±0. 04) and (0. 26±0. 02) vs. (0. 17±0. 03);P＜0. 01], while IUGR group higher than L-Arg treated group ( P＜0. 05 ) . Conclusions The kidney of IUGR rats showed reduced glomerular number, increased renal cell apoptosis, enhanced p53 protein expression, increased proliferation of glomerular mesangial cells, decreased foot process, and partial fusion of foot process. And L-Arg could to some extent improve the organizational structure of the kidney in IUGR rats.
