AIMTo describe an unusual symptom of benign prostatic hyperplasia (BPH).

METHODSA patient presented to our urology clinic having experienced post-coital gross hematuria for 2 years. He had not experienced lower urinary tract symptoms (LUTS). A series of examinations were performed to determine the source of bleeding.

RESULTSThe prostate was defined as the active bleeding source responsible for the patient's post-coital hematuria. Endoscopic fulguration did not alleviate the symptom. The use of dutasteride, a dual inhibitor of 5alpha-reductase, solved the problem.

CONCLUSIONThis study reports for the first time that post-coital gross hematuria is one of the clinical presentations of BPH, which can be successfully treated with 5alpha-reductase inhibitor.

OBJECTIVETo explore the effect of Sedum sarmentosum Bunge Extract (SSBE) on severe acute pancreatitis (SAP) induced acute lung injury (ALI) model rats and their excessive inflammatory reactions.

METHODSForty-two healthy adult male Sprague-Dawley (SD) rats were randomly divided into 3 groups, the sham-operated control group (C), the SAP group (SAP), and the SSBE treated group (SSBE), 14 in each group. SAP induced ALl rat model was induced by retrograde injection of 5% sodium taurocholate (1 mL/kg) into the pancreatic duct. SSBE (100 m/kg) was administrated subcutaneously after the establishment of the SAP model. Equal dose of SSBE was injected again 12 h later. Equal volume of normal saline was administrated in the same way for rats in the C group and the SAP group. Rats were sacrificed after successful modeling and samples taken at 12 and 24 h. Pathological changes in the pancreas and the lung tissue were observed under light microscope. The ascites, serum amylase (AMS), wet/dry proportion (W/D) of the lung tissue, activities of myeloperoxidase (MPO), interleukin-1 (IL-1), IL-6, and tumor necrosis factor-alpha (TNF-alpha) were also measured.

RESULTSAscites and serum AMS activities significantly increased; MPO, IL-1, IL-6, TNF-alpha contents, and W/D ratio also significantly increased in the SAP group, when compared with the C group (P<0.05). Compared with the SAP group, those parameters were all attenuated in the SSBE group at 12 and 24 h (P<0.05, P<0.01). Pathological changes in the pancreas and the lung tissue were alleviated in the SSBE group under light microscope. The injury degree ranged between that of the C group and the SAP group.

CONCLUSIONSSBE could relieve the ALl in SAP model rats, which could be achieved through alleviating inflammation responses of SAP rats.

Objective To evaluate the possibility and curative effect of total en bloc spondylectomy (TES) for the treatment of primary tumors of the lumbar spine. MethodsBetween June 2005 and July 2009,nine cases of primary tumor of the lumbar spine were treated with total en bloc spondylectomy through a single posterior approach performed in seven cases(L1 giant cell tumor, L1 osteosarcoma, L2 giant cell tumor,L2 solitary plasmacytoma, L2 chondrosarcoma, L2 chordoma, and L3 histiocytic sarcoma), and two cases through a single stage anterior and posterior combined approach (L4 giant cell tumor with paraspinal mass and L4 fibrosarcoma). They were performed a single stage reconstruction after removing tumors of vertebra. Neurofunction was evaluated perioperatively and recurrence of tumor was tracked for all cases.ResultsThe follow up was obtained for 3-49 months (averaging 19 months). All patients attained significant clinical improvement after surgery without any severe complications. There was no local recurrence and distal metastasis in shortterm follow-up. ConclusionThe treatment by TES to remove tumors and reconstruction of spine are reliable for primary tumors of the lumbar spine. The curative effect of short-term follow-up is satisfactory. However, the long-term curative effect remain to be further follow-up.

Objective To investigate the feasibility and safety of transvaginal endoscopic cholecystectomy.Methods The clinical data of 88 female patients who underwent cholecystectomy at the Qilu Hospital of Shandong University from May to November, 2009 were retrospectively analysed. Among all the patients, 32 received transvaginal endoscopic cholecystectomy ( NOTES group) and the remaining 56 patients received laparoscopic cholecystectomy (LC). Thirty-two patients who received LC at the same period were selected (LC group)acccording to age, body mass index, type and severity of disease to conduct a matched case-control study. The differences in time span of postoperative pain, anodyne dose, enterokinesia recovery time, operation time, out-ofbed activity time, average hospital stay and hospitalization expenses between the two groups were compared using the paired t test. Results Cholecystectomies were successfully carried out for all the patients. The intraoperative blood loss, operation time, degree of pain, anodyne doses, enterokinesia recovery time, out-of-bed activity time,average hospital stay and hospitalization expenses were (5.7 ± 1.5 ) ml, ( 76 ± 27 ) minutes, 2.2 ± 0.6, ( 10 ±6) mg, (25±5) hours, (9±3) hours, (2.1 ±1.2) days and (1.12±0.34) ×104 yuan in NOTES group, and they were ( 13.9 ± 3.1 ) ml, (38 ± 16) minutes, 6.7 ± 1.5, (28 ± 8) mg, (45 ± 8) hours, (26 ± 6) hours,(4.3 ± 2.1 ) days and ( 1.54 ± 0.18 ) × 104 yuan in the LC group. There were significant differences between the two groups (t = 5.098, - 4.712, 2.417, 3.203, 3.089, 4.136, 4.786, 3.917, P ＜ 0.05 ). Conclusion Transvaginal endoscopic cholecystectomy is safe and feasible, and it is superior to tranditional LC.

OBJECTIVETo explore the effect of Salvianolate on myosin heavy chain (MHC) in cardiomyocytes of congestive heart failure (CHF) rats.

METHODSSixty male SD rats were divided into 6 groups according to random digit table, i.e., the normal control group (NCG), the model group, the Captopril group (CAG), the low dose Salvianolate group (LSG), the high dose Salvianolate group (HSG), the Captopril and high dose Salvianolate group (CSG), 10 in each group. CHF rat model was established with peritoneal injection of adriamycin in all rats except those in the NCG. Equal volume of normal saline was peritoneally injected to rats in the NCG, once per week for 6 successive weeks. Corresponding medication was started from the 5th week of injecting adriamycin. Rats in the CAG were administered with Captopril solution at the daily dose of 10 mg/kg by gastrogavage. Rats in the LSG and the HSG were administered with Salvianolate solution at the daily dose of 24.219 mg/kg and 48.438 mg/kg respectively by gastrogavage. Salvianolate was dissolved in 2 mL 5% glucose solution and administered by peritoneal injection. Rats in the CSG were peritoneally injected with high dose Salvianolate solution and administered with Captopril solution by gastrogavage. Two mL normal saline was peritoneally injected to rats in the model group, once per day for 8 successive weeks. Eight weeks later, the cardiac function and myocardial hypertrophy indices were detected by biological signal collecting and processing system. mRNA expression levels of alpha-MHC and beta-MHC in cardiac muscle were detected by fluorescence quantitative PCR. Expressions of protein kinase C (PKC) in cardiac muscle were detected by Western blot.

RESULTSCompared with the normal control group, heart mass index (HMI) and left ventricular mass index (LVMI) obviously increased in the model group (P < 0.01). Compared with the model group, HMI and LVMI decreased in HSG, CAG, and CSG groups (P < 0.05, P < 0.01). It was more obviously lowered in the CSG group than in the CAG group (P < 0.05). Compared with the NCG, the mRNA expression level of alpha-MHC in cardiac muscle decreased, the mRNA expression level of p-MHC and the expression of PKC in cardiac muscle increased in the model group (P < 0.01). Compared with the model group, the mRNA expression level of alpha-MHC in cardiac muscle was increased, and the mRNA expression level of beta-MHC and the expression of PKC in cardiac muscle were decreased in HSG, CAG, and CSG groups (P < 0.05, P < 0.01). There was statistical difference between the CSG group and the CAG group (P < 0.05).

CONCLUSIONSSalvianolate could up-regulate the mRNA expression level of alpha-MHC, and down-regulate the mRNA expression level of beta-MHC in cardiac muscle. Its mechanism might be related to decreasing the expression of PKC.
