Objective To discuss clinical effects of transurethral electrovaporization of the prostate(TUVP) for the treatment of large benign prostatic hyperplasia(BPH).Methods A total of 126 cases of large BPH were treated with TUVP.Two longitudinal trenches were made at the position of 6 and 12 o'clock,respectively.Then the lateral lobe was retrogradely dissected from the proximal end of the seminal colliculus and was removed.Results The international prostate symptom scores(IPSS) decreased from 28.6?4.5 preoperatively to 10.7?2.6 postoperatively(t=38.661,P=0.000);the quality-of-life scores(QOL) decreased from 5.3?0.7 preoperatively to(2.0?)0.5 postoperatively(t=43.061,P=0.000);the maximum urinary flow rate(Qmax) increased from 5.7?3.6 ml/s preoperatively to 18.2?4.2 ml/s postoperatively(t=-25.365,P=0.000);the resident urine(RU) decreased from 312.4?56.6 ml preoperatively to 32.8?9.2 ml postoperatively(t=54.732,P=0.000).There were significant differences in all these parameters between preoperatively and postoperatively.Threatened transurethral resection syndrome(TURS) occurred during operation in 2 cases.Postoperatively,transient urinary incontinence was observed in 5 cases.Conclusions Transurethral electrovaporization of the prostate for the treatment of large BPH is effective and safe.

Objective To study the therapeutic effect of pinaverium bromid and oryz-aspergillus enzyme and pancreatin tablet on patients with bile duct Ⅲ of sphincter of Oddi dysfunction (SOD) after cholecystectomy.Methods 72 patients who had a diagnosis consistent with bile duct Ⅲ of SOD seen from February 2010 to February 2013 in our hospital were randomly divided into the control group and the treatment group.Patients in the control group were given pinaverium bromid for 3 months while patients in the treatment group were,in addition to pinaverium bromid,given oryz-aspergillus enzyme and pancreatin tablet.Relief of abdominal pain,abdominal distention and recurrence of the above symptoms after drug withdrawal were studied.Results The scores on abdominal pain in the treatment group before and after treatment were 7.5 ± 1.1 and 3.0 ± 1.6 (P ＜ 0.05) while the scores in the control group were 7.4 ± 1.1 and 5.0 ± 1.4 (P ＜ 0.05),respectively.Alleviation of abdominal pain in the treatment group was superior to the control group (P ＜ 0.05).The scores on abdominal distention in the treatment group before and after treatment were 5.4 ± 0.6 and 1.6 ± 0.5 (P ＜ 0.05) while the scores in the control group were 5.2 ± 0.5 and 4.7 ± 0.8 (P ＞ 0.05),respectively.Alleviation of abdominal distention in the treatment group was superior to the control group (P ＜0.05).The scores of abdominal pain and distention in half year after 3 months' therapy in the treatment group were 3.1 ± 1.7 and 1.7 ± 1.1,respectively,which obviously were lower than the control group (5.4 ± 1.4 and 5.0 ± 0.6,P ＜ 0.05).Conclusions Pinaverium bromid and oryz-aspergillus enzyme and pancreatin tablet could effectively alleviate abdominal pain and distention in patients with bile duct Ⅲ of SOD after cholecystectomy and the recurrence rates of symptoms were significantly lower.

Objective To evaluate the mechanism of immunosuppressive activity of 1,25-dihydroxyvitamin D_3 and provide a theoretical basis for clinical use. Methods Different inbred strain male BALB/C (H-2d) and male C57BL/6(H-2b) mice were used as skin transplantation donors and recipients, respectively. After operation C57BL/6 mice were conditioned with 1,25-dihydroxyvitamin D_3 2.5 ??g/kg every day, Cyclosporine A (CsA) po 25 mg/kg every day separately or unitedly. Ten days after transplantation, the recipients were sacrificed, and the spleens were collected. The mouse splenic T lymphocytic subsets, mixed lymphocyte reaction (MLR), the activity of natural killer (NK) cells were determined. Results The mean survival time (MST) of skin allografts was prolonged from ( 9.75 ? 0.89 ) days to ( 13.13 ? 1.13 ) days by treatment of the recipient mice with 1,25-dihydroxyvitamin D_3. CD3 + and CD4 + subset percentage in 1,25-dihydroxyvitamin D_3 group was lower than that in control group CD3 + ( 40.19 ? 4.25 )% vs ( 48.70 ? 7.19 )%, P

Objective To evaluate the safety of simultaneous transurethral green laser vaporization therapy in benign prostatic hyperplasia (BPH) and nonmuscle-invasive bladder transitional cell carcinoma (NMIBT).Methods The clinical data of 27 patients (observation group) who had undergone simultaneous transurethral green laser vaporization therapy in BPH and NMIBT between May 2004 and October 2010 were analyzed retrospectively.Meanwhile 27 patients(control group) only had undergone green laser vaporization therapy in NMIBT during the same period were selected.Clinicopathologic parameters,rate of recurrence and progression,rate of recurrence in the bladder neck and prostatic urethra were determined and compared.Results The time of follow-up in observation group and control group were (28.61 ± 19.53) and (30.20 ± 21.46) months.The rates of recurrence,progression and recurrence in the bladder neck and prostatic urethra between observation group and control group had no significant differences [ 18.5％ (5/27) vs.25.9％ (7/27),3.7％ (1/27) vs.0,0 vs.0] (P ＞0.05).Conclusion Simultaneous transurethral green laser vaporization of NMIBT and BPH can be safely performed without increasing the risk of tumor recurrence in the prostatic urethra.

Objective To detect the effect of deep hypothermia on the function of mitochondria in hippocampus after global ischemia in rats and to explore the protection mechanism. Methods The animal model of cardiopulmonary bypass (CPB) was established in rats that were then randomly divided into three groups,ie,control group,normothermia ischemia group and hypothermia ischemia group,eight rats per group.The mitochondria was extracted from the hippocampus of each rats for observing the mitochondrial respiratory function,the activities of succinate dehydrogenase (SDH),the cytochrome oxidese(CCO),the lnembrane fluidity and the content of intramitochondria free calcium and MDA. Resuits The content of intramitochondria free calcium and MDA in the normothermia ischemia group was increased significantly compared to the control group and that in the hypothermia ischemia group wag decreased significantly compared with the normothermia ischemia group(P<0.05).Respiratory state Ⅲ (R3),respiratory state IV(R4),P/O ratio and oxidative phosphorylation (OPR) in the normothermia ischemia group were decreased significantly compared to the control group (P<0.05).R3,R4,P/O ratio and OPR in the hypothermia ischemia group were increased significantly compared with the normothermia ischemia group (P<0.05).Membrane fluidity in the normothermia ischemia group wag decreased significantly compared to the control group (P<0.01),while that in the hypothermia ischemia group was increased significantly compared with the normothermia ischemia group(P<0.05).The activities of SDH and CCO in the normothermia ischemia group were decreased significantly compared to the control group (P<0.01),while those in the hypothermia ischemia group were increased significantly compared with the normothermia ischemia group (P<0.05). Conclusion Profound hypothermia exerts a protective effect on the function of mitochondria in the hippocampus after global ischemia in rats.

ObJective To discuss the causes,diagnosis,treatment and outcomes of renal artery aneurysm(RAA). Methods Duriog August 1998 and December 2004,1251 patients underwent rehal transplantation,and 5 men(mean age,43)who received end-to-end anastomose from renal graft artery to the internal iliac artery were found to develop RAA.The main complains included aggravated renal function,sudden oliguria or anuria,hypertension and allograft pain.Color Doppler flow and digital subtraction angiography were used to confirm aneurysm.Size of the RAA were 1.8 cm×2.0 cm×2.0 am to 4.0 cm×4.0 cm×5.0 cm. Results Two aneurysms were located at the anastomotic stoma.One patient who lost renal function 1 month after the aneurysm was diagnosed received nephrectomy,regular hemodialysis,and another renal transplantation 1 year later.The other patient successfully underwent cadaver transplantation without removing the original renal allograft after the renal dysfunction occurred.The renal function remained normal during 2 years'follow-up.Two renal artery aneurysm cases also accompanied with proximate renal artery stenosis.One patient was treated with balloon dilatation and stent implantation,and normal renal function was observed during 1 years followup. Another patient had graft removed and underwent retransplantation.The renal function was excellent during 3 years'follow-up.Atherosclerotic plaque within internal iliac artery anastomotic stoma,which lead to artery stenosis and aneurysm,was found in 1 patient.Two days after the renal allograft was removed,this patient died of brainstem embolism. Conclusions End-to-end anastomose from renal graft artery to the internal iliac artery seems to be related with postoperative complications.Patients with confirmed RAA should be cautiously managed.Retransplantation and interventional thera PY may be the choice.

OBJECTIVE: To observe the protective effect of Huaxia shallot preparation on human umbilical vein endothelial cell (HUVEC) injury induced by oxidized low density lipoprotein (Ox-LDL) in vitro. METHODS: Ox-LDL was prepared and identified, and HUVECs were cultured. After 2-hour intervention of different drugs and 24-hour following intervention of Ox-LDL, the number of HUVECs was observed by phase contrast optical microscope and the activity of the HUVECs was observed by methyl thiazolyl tetrazolium (MTT) technique. Superoxide dismutase (SOD) activity and nitric oxide (NO) content were assayed by respective kit. The protein expressions and mRNA levels of peroxisome proliferators activated receptor gamma(PPAR-gamma) and endothelial nitric oxide synthase (eNOS) were measured by western blot technique and reverse transcription polymerase chain reaction (RT-PCR). RESULTS: Ox-LDL could increase the apoptosis rate of the HUVECs and decrease the NO release as compared with the blank control group (P<0.05). These effects induced by Ox-LDL were all significantly inhibited by Huaxia shallot preparation. It could up-regulate the protein expressions and mRNA levels of PPAR-gamma and eNOS significantly (P<0.05). Huaxia shallot preparation could decrease the apoptosis rate of the HUVECs. CONCLUSION: Ox-LDL may be involved in the initiation and progression of atherosclerosis by injuring the endothelial cells directly and may cause the endothelial dysfunction. Huaxia shallot preparation can protect against Ox-LDL induced endothelial cell injury by up-regulating the protein expressions and mRNA levels of PPAR-gamma and eNOS. It suggests that Huaxia shallot preparation may play a role in the prevention and treatment of cardiovascular disease.

Objective To explore the relationships among attachment,parental attachment and parental rearing style of adolescent depression.Methods 36 outpatients and hospital patients in Anhui Mental Health Center with depression and their parents were involved as the case group,33 age-,gender-,and education-matched high school students and their parents as the normal controls.The case group and control group were assessed with Experiences in Close Relationships Inventory (ECR) and Parental Rearing Pattern Questionnaire (EMBU).Results ① The score of attachment avoidance and anxiety dimension in the depression group were obviously higher than that of the control group(73.19 ± 16.63 vs 66.25 ± 12.91,62.76 ± 13.90 vs 51.97 ± 13.69,P ＜ 0.01) ;the score of mother's attachment anxiety in the depression group were significantly higher than that of the control group (72.06 ± 14.23 vs 57.42 ± 12.81),and there were significant differences between two groups (P ＜ 0.01).②The attachment avoidance was positively correlated with parental attachment avoidance in the depression group (r =0.534,r=0.488 ; P＜ 0.01).The attachment anxiety dimension was positively correlated with mother's attachment anxiety in depression group (r =0.532,P ＜ 0.01).Attachment avoidance was negatively correlated with parental warmness(r =-0.406,r =-0.462,P ＜ 0.01),however attachment avoidance had positive correlation with father's punishment and mother's rejection in depression group (r=0.395,r=0.468; P＜0.05).Father's attachment avoidance was negatively correlated with father's warmness(r =-0.527,P＜ 0.01),and mother's attachment avoidance was negatively correlated with mother's warmness (r =-0.491,P ＜ 0.01),which was positively correlated with mother's rejection (r =0.392,P ＜ 0.05).③ Regression analysis showed that mother's warmness rearing style had full mediating effect on the relationship between mother's attachment avoidance and attachment avoidance in depression group,and then mother's refused rearing style partly mediated the relationship between them.But father's warmness didn(t) have mediating effect on the relationship between father's attachment avoidance and attachment avoidance in depression group.Conclusion The attachment pattern is insecure in the depression group.Parenting attachment and rearing style significantly influence on adolescent depression attachment patterns,and mother's rearing style has mediating effect on the relationship between mother's attachment and depression attachment.

Objective To review the results and complications of open reduction and internal fixation (ORIF) through the posteromedial approach for posterior pilon fractures.Methods From March 2009 through November 2013,18 consecutive posterior pilon fractures were surgically treated through the posteromedial approach,involving 12 males and 6 females.Their ages ranged from 15 to 65 years (average,42 years).All of them were complicated with fracture of external malleolus,and 6 of them with fracture of anterior colliculus of medial malleolus.The time from injury to surgery ranged from 2 to 15 days (average,7 days).Results The patients were followed up for an average of 15 months (range,from 10 to 19 months).All the fractures healed after 11 to 16 weeks (average,13 weeks).No complications like neurovascular injury,implants failure,nonunion,or malunion occurred,except one case of superficial wound infection which responded to nonoperative management.According to the AOFAS (American Orthopaedic Foot and Ankle Society) evaluation system,15 cases were excellent,2 cases good and one case fair.Conclusion It is safe,reliable and effective to treat posterior pilon fractures using anti-rotation plate ORIF through the posteromedial approach.

Purpose To investigate the clinicopathlogical characteristics, diagnosis and differential diagnosis of ovarian small cell car-cinoma hypercalcemic type ( OSCCHT) associated with acute renal dysfunction. Methods A case of OSCCHT associated with acute renal dysfunction was reported. The clinical and pathologic data, treatment and pathological examinations were analyzed and the related literatures were reviewed. Results A 29-year-olds women was presented to hospital with inappetence and significant weight loss for 2 months. The laboratory examination showed abnormal renal function, and pelvic cavity mass, possibly coming from adnexa of the uterus was seen by radiography. Serum levels showed significantly increased serum calcium with acute renal dysfunction. An emergency opera-tion was performed just after renal function partially recovered by 2 times hemodialysis. During surgery, right ovary tumor with a size of 12 cm × 10 cm × 10 cm was inspected. Microscopically, the tumor cells were arranged in a diffuse solid pattern, mutiple nodules were separated by fibrous tissue. some small folliculars and pseudoglandular cavities with acidophilia secretion within nodules could been ob-served. Tumor cells were medium to large with eosinophilic cytoplasm, round or oval vesicular nucleus, increased karyoplasmic ratio and pathologic mitosis. Immunohistochemistry revealed that the tumor cells expressed EMA, CKpan, C-erbB-2 ( +) , CA125 ( focal+) and Ki-67 proliferation index was about 60%, while ER, PR, Syn, CgA, PTH, Inhibin, CD99, AFP, PLAP, CD30 and CD20 were not expressed. Conclusion Ovarian small cell carcinoma hypercalcemic type with acute renal dysfunction is a very rare with a rapidly progressive and highly malignant tumor. The final diagnosis mainly lies on clinical information ( hypercalcaemia) , morphology and immunohistochemistry, combined with electron microscopy and molecular biological detection when necessary.
