Objective: To compare the clinical effects of different minimally invasive surgeries in the treatment of varicose veins of lower extremities, and to explore their application values. Methods: A total of 201 patients with varicose veins of lower extremities were selected and treated with different operation methods. 52 cases were treated by endovenous laser therapy (EVLA group), 46 cases were treated by transilluminated powered phlebectomy (TIPP group), 49 cases were treated by EVLA combined subfascial endoscopic perforator surgery (SEPS) (EVLA + SEPS group) and 54 cases were treated by TIPP combined SEPS (TIPP + SEPS) group. The operation time, the intraoperative blood loss, the postoperative hospitalization cost, the hospitalization time, the incidence rates of postoperative complications (residual varicose veins, subcutaneous induration, superficial phlebitis, skin necrosis differences in the operation time, the intraoperative blood loss and the postoperative hospitalization time, the hospitalization cost of the patients between various groups (P<0.05). Compared with EVLA group, the incidence rats of residual varicose veins, superficial phlebitis, and lower extremity swelling and ecchymosis of the patients in TIPP group were significantly decreased (P<0.05); the incidence rates of subcutaneous induration, wound hematoma, saphenous nerve injury and skin numbness were increased, but there were no significant differences (P>0.05). Compared with EVLA group and TIPP group, the incidence rates of reidual varicose veins and superficial phlebitis in EVLA + SEPS group and TIPP + SEPS group were significantly decreased (P<0.05). The healing rates of the patients 3 months after operation in TIPP group, EVLA + SEPS group and TIPP + SEPS group were significantly increased compared with EVLA group (P<0.05). The recurrence rates 1 year after operation in TIPP group, EVLA + SEPS group and TIPP + SEPS group were lower than that in EVLA group (P<0.05). Conclusion: The curative effects of EVLA combined with SEPS and TIPP combined with SEPS in treatment of varicose veins in lower extremities are superior to EVLA and TIPP, with the advantages of safe and reliable methods, complete varicose vein resection, less postoperative complications, quick ulcer healing and low recurrence rate and so on.

Objective To observe the clinical effect of procedure for prolapse and hemorrhoids (PPH) in treating hemorrhoids.Methods 78 patients with symptomatic Ⅱ,Ⅲ and Ⅳ degree hemorrhoids undergoing PPH were selected in this study.The diagnosis,medical history,operative time,blood loss and perioperative complications were recorded.The World Health Organization Quality of Life Scale(WHOQOL-BREF) was observed preoperation and 6 hours,24 hours,1 month postoperation.Results The postoperative pain score measured by visual analogue scale (VAS) at postoperative six hours was (7.6 ± 2.1),which reduced to (1.3 ± 1.1) at 24 hours.There was significant improvement in the overall perception of QOL,health,and in physical and psychological domains (t =1.901,1.805,1.714,P =0.041,0.038,0.029,all P ＜ 0.05).There was modest improvement in environmental domain,while no change was found in social domain (P ＞ 0.05).Conclusion PPH surgery achieves good clinical results,improved quality of life of patients,with a low incidence of complications,patients with hemorrhoids should be recommended for this preferred surgical approach.

Objective To assess the long-term surgical outcomes,patient's satisfaction and functional results of correction for patients with penile curvature by 16-dot minimal tension plication.Methods Between August 2004 and December 2010,92 patients with penile curvature underwent surgical correction of penile curvature by 16-dot minimal tension plication.Of them,86 patients (53 patients with congenital penile curvature and 33 patients with Peyronie's disease (PD)) were reached for long-term follow-up.Indications for operation included patients with 30 to 90 degrees of penile curvature,penile length greater than 10 cm and patients who had one or more symptoms,such as difficulty or inability to vaginal penetration and partner discomfort during sexual intercourse.Patients were excluded from study if they had severe penile curvature (greater than 90 degrees),hourglass deformities or large plaques.Preoperative evaluation included international index of erectile function 5 (IIEF-5) questionnaire score,pain on erection and physical examination.Patients were recommended daily low dose phosphodiesterase type 5 (PDE-5) inhibitors 2 weeks after surgery and maintained for 2 to 3 months.At follow-up,recurrence rate,complications,erectile function,patients and partner's satisfaction with the surgery were assessed.Results The mean time of follow-up was 79 months (range,35-107 months).Of 86 patients who had been reached for long-term follow up,82 patients (95.3％) and 77 partners (89.5％) reported overall satisfaction after the surgery.Complete penile straightening was achieved in 79 patients (91.8％).Slight residual curvatures were observed in 7 patients,but did not affect their sexual intercourse.Postoperative penile length shortening (median penile length loss 1.3 cm) was noted in 35 patients (40.7％),which did not affect their sexual intercourse.In addition,no de novo erectile dysfunction was observed,and sexual function was significantly improved evidenced by the IIEF-5 scores,especially in the patients who had received PDE-5 inhibitors for 2 to 3 months.There were no surgery-related complications,such as hematoma,urethral injury,or infection.Conclusion The longterm results demonstrate that correction of penile curvature using 16-dot plication is a simple and safe method to achieve cosmetic and functional satisfaction in patients with mild to moderate penile curvature.

Objective To investigate the effects of exogenous wild DCC gene stably transfection on growth of colorectal carcinoma cell line SW1116 in vitro. Methods DCC gene domain was amplified from human normal colon tissue by reverse transcript-polymerase chain reaction(RT-PCR). At first,a recombinant expression plasmid pcDNA3. 1( + )-DCC was constructed. Human colorectal carcinoma cell line SW1116 with-out DCC gene was transfected with pcDNA3. 1-DCC. Cell viability was tested by methyl thiazolyl tetrazolium (MTT)assay. Immunofluorescence staining was used to determine the effects of pcDNA3. 1-DCC and expres-sion of carcino-embryonic antigen(CEA)in human colorectal carcinoma cell line SW1116 which was transfect-ed with pcDNA3. 1-DCC. Results The population of cells transfected with pcDNA3. 1( + )-DCC plasmid was lower than those with pcDNA3. 1( + )-DCC plasmid and normal cells(t = 3. 645,P ﹤ 0. 05;t = 3. 132,P ﹤0. 05)at 3 ~ 6 days after transfection,and the proliferation rate of cells transfected with pcDNA3. 1( + )-DCC plasmid was lower than those with pcDNA3. 1( + )plasmid and normal cells(t = 2. 134,P ﹤ 0. 05;t = 2. 736, P ﹤ 0. 05). Cell line SW1116 transfected with pcDNA3. 1( + )-DCC plasmid total viability was lower than nor-mal cells(t = 3. 053 ,P ﹤ 0. 05)at 2 ~ 6 days after transfection. Cell line SW1116 transfected with pcDNA3. 1 ( + )-DCC plasmid total viability was lower than those with pcDNA3. 1( + )plasmid(t = 2. 816,P ﹤ 0. 05)at 2,4,5,6 days after transfection. The population of flavo-green colour cells transfected with pcDNA3. 1( + )-DCC plasmid and the fluorescent intensity of these cells were lower than those with pcDNA3. 1( + )plasmid and normal control cells. Conclusion Transfected DCC gene can suppress the cell proliferation and make CEA expression of cell line SW1116 down regulation to weaken its infiltration and metastasis abilities.

Five groups were assigned to include intrahepatic cholangiocarcinoma ( ICC, n=30 ) , liver cirrhosis (LC,n=30),metastatic carcinoma (MCA,n=30) and 30 healthy subjects.The serum level of GPC3 was measured by a sandwich method of enzyme-linked immunosorbent assay ( ELISA ) and alpha-fetoprotein (AFP) by microparticle enzyme immunoassay (MEIA).The serum levels of GPC3 and AFP were significantly higher than those of other groups (P<0.05).At a cut-off value of 3.5μg/L,the sensitivity and specificity of GPC3 in the diagnosis of HCC was 83.3%and 76.7%respectively.The sensitivity of combined measurement of GPC3 and AFP was better than GPC3 or AFP alone.Detectable GPC3 was significantly correlated with the presence of viral hepatitis markers and tumor size.However there was no obvious difference in tumor thrombi in portal vein ( PVTT), tumor number, age, gender or hepatic function of HCC.Thus,as a sensitive serum diagnostic marker for HCC ,GPC3 may be a good supplement to AFP in differentiating HCC from non-malignant chronic liver diseases and other liver cancers.

Objective To investigate the blood pressure control effect of captopril sustained-releasetablets based combination, antihypertensive therapy on hospitalized high-risk patients with hypertension in high altitude region. Methods According to the blood pressure,risk factors and combined target organ damage,331 hospitalized patients with essential hypertension were divided into 2 groups and accepted different treatment:low-risk group had monotherapy (n=102) , and night-risk group had captopril sustained-release-tablets based combination antihypertensive therapy (n =229). The discharge blood pressure,extent of SBP/DBP decrease and the compliance rate of discharge blood pressure of two groups were compared. Results The extent of SBP/DBP decrease in hight-risk group was significantly greater than low-risk group (SBP [36. 83 ± 22. 23] mm Hg vs.[28. 74 ±18.71] mm Hg,t=-3. 207,P <0. 05;DBP[22. 04±13. 57]mm Hg vs. [17. 98 ± 13.63] mm Hg,t =-2. 509, P < 0.05). The average discharge blood pressure in both groups reach the standard criterion, but no significant difference was observed between the two groups (SBP [125. 62 ± 14. 74] mm Hg vs. [122. 28 ±13.13]mmHg,t=-1. 962,P>0. 05;DBP[80. 67 ±9. 82]mm Hg vs. [78. 40 ±9. 97]mm Hg,t =-1.910,P > 0. 05). Furthermore we found no significant difference in the control rate of blood pressure between high-risk and low-risk group (72. 06% vs. 71. 57% , x2 = 0.928, P > 0. 05). Conclusion The captopril sustainedrelease-tablets based combination antihypertensive therapy is a reliable treatment in high-risk patients with hypertension from high altitude region,which shows satisfying blood pressure control rate.

Objective To evaluate the effectiveness and safety of open tension-free hernioplasty and two kind of laparoscopic hernia repair for the treatment of primary unilateral inguinal hernia. Methods Patients suffering from primary unilateral inguinal hernia were randomly divided into 3 groups to undergoopen operation with mesh-plug and patch or transabdominal preperitoneal hernioplasty (TAPP) or totally extraperitoneal hernioplasty (ZEP). Results From February 2006 to February 2009, a total of 164patients were divided into 3 groups, with 62 undergoing open tension-free mesh-plug hernia repair, 50receiving TAPP and 52 receiving TEP. Postoperative patients were then followed up for a period of(16±8)months. The average operating time for the patients in the open mesh repair group was significantly shorter compared to the other two groups (P＜0.01 ). The cost in the open mesh repair group was also significantly lower than the other two groups (P＜0.01). The pain scores in open mesh group were significantly higher than those in the other two groups (P＜0.01). The hospital stay and the recovery time were both significantly longer in the open mesh repair group (P＜0.01) compared to the other two groups. No major complications and recurrence was found in neither groups. Conclusions Open tension-free mesh-plug hernia repair, TAPP and TEP are all safe and effective for the treatment for patients with primary unilateral inguinal hernia. TAPP and TEP are superior to open tension-free mesh-plug hernia repair as these two procedures involve less postoperative pain and fast recovery.
