OBJECTIVETo explore the treatment of urethral stricture.

METHODSWe retrospectively studied the clinical data of 1 case of long anterior urethral stricture treated by urethroplasty with pedunculated preputial flap and testicular tunica vaginalis, and summarized the treatment of the disease with review of the relevant literature.

RESULTSThe operation was smooth and successful, and no such complications as fistula and urethral stricture were found during the follow-up.

CONCLUSIONUrethroplasty with pedunculated preputial flap and testicular tunica vaginalis as a substitute is feasible for the treatment of urethral stricture. The key to a successful operation is the proper choice of a urethral substitute.

Objective To investigate the correlation between inflammatory cells, body temperature changes, and TCM syndromes of deep venous thrombosis (DVT) patients in acute and subacute phases. Methods The data of age, gender, body temperature, blood routine, venous ultrasonography, and four diagnostic information of 130 DVT patients in acute and subcute phases were collected and analyzed in a cross-sectional study. The correlation between inflammatory cells and the changes of body temperature and TCM syndromes were analyzed. Results Among 130 DVT patients, 37 patients had damp-heat syndrome, 64 patients had blood stasis and dampness syndrome, and 29 patients had qi stagnation syndrome. Neutrophils increased most obviously in blood stasis and dampness syndrome (P<0.05), which had close correlation with the skin redness (OR=1.287, 95%CI: 9.412-21.247). The mononuclear cells increased most obviously in the damp-heat syndrome, which has close correlation with nouhof (OR=7.364, 95%CI:1.189–45.603), high skin temperature (OR=6.683, 95%CI:1.791–24.938), skin tightness (OR=6.107, 95%CI:1.423–26.203) and weakness (OR=3.302, 95%CI: 1.002–9.169). The temperature rising was the most common in the damp-heat syndrome, and the increase of mononuclear cells was the most common one. Conclusion DVT is often accompanied with elevated levels of inflammatory cells and body temperature. Damp-heat syndrome has close correlation with body temperature and mononuclear cells increasing. Dampness and blood stasis syndrome and neutrophils are closely related.

Objective To evaluate the clinical significance of bone scintigraphy in the preoperative diagnosis of sacral tumor. Methods Preoperative 99Tcm-methylene diphosphonate (MDP) whole body bone scintigraphy was performed in total of 103 patients with sacral tumor for whole body survey and radionuclide uptake in the sacral tumor. Of these 103 patients,39 had SPECT. According to the osteoblastic reaction in bone SPECT studies,patterns of tumor with a "hot" lesion was defined as type Ⅰ,a "cold" lesion accompanied with partial uptake was defined as type Ⅱ,a purely "cold" lesion was defined as type Ⅲ,and a "cold" lesion with marginal uptake which produced "doughnut sign" was defined as type Ⅳ. Imaging interpretation was correlated with the final pathologic diagnosis. Results Of the 103 patients,18 ( 17.5% ) had polyostotic involvement. About 46.6% (48/103 ) in planar and 84.6% ( 33/39 ) in SPECT showed decreased uptake at sacrum. Of the bone metastatic patients (n =21 ) ,12 (51.7%) had sole metastasis to sacrum. Tumor with type Ⅰ (6/6) or type Ⅱ (16/19) uptake was likely to be a malignancy,whereas type Ⅲ uptake tended to occur in the benign disease in those patients without polyostotic involvement( 5/7 ),and type Ⅳ was all appeared in giant cell tumors( n = 5 ). Conclusions Preoperative bone scintigraphy is useful in examination of polyostotic involvement for the patients with sacral tumor,but it is limited for diagnosing isolated sacral metastatic disease. Tumor uptake on bone scintigraphy can be helpful in differential diagnosis of sacral tumor.

BACKGROUNDGenetic mechanisms contribute to blood pressure regulation. This study investigated whether glutathione peroxidase (GPx-3) tag single nucleotide polymorphisms (SNPs) are associated with hypertension in the rural areas of Fuxin county, Liaoning province, China.

METHODSIndigenous Fuxin Han people participated, 523 unrelated hypertensives and 547 controls were recruited. All tag SNPs of GPx-3 gene were selected. We estimated SNP allele frequency in DNA pools with pyrosequencing.

RESULTSBefore Bonferroni correction, C allele frequency for rs8177417 was significantly higher in hypertensives than those in controls (23.4% vs. 19.3%, P = 0.014); T allele frequency for rs3828599 was significantly lower in hypertensives than those in controls (35.6% vs. 40.8%, P = 0.009). However, when a Bonferroni correction for multiple testing was applied, only the polymorphisms rs3828599 of GPx-3 gene was associated with hypertension (P = 0.045, OR: 0.833, 95%CI: 0.695 - 0.998).

CONCLUSIONThe polymorphism of rs3828599 of GPx-3 gene might be associated with hypertension in rural Han Chinese from Fuxin, Liaoning.
