Objective To analyze postoperative complications of surgical therapy for deep vein thrombosis (DVT) of the lower extremity. Method From January 2001 to January 2008 vena cava filters were placed in 171 DVT cases before surgery. Fogarty catheter (73 cases), Amplatz thrombectomy device (ATD) (55 cases), Acolysis ultrasound ablation(43 cases) were used to extract the thrombi in iliac and proximal femoral vein. The full extraction of thrombi in distal end was facilitated by compressing and massaging the legs in all cases. Iliac venous stenosis or occlusion was managed by interventional therapy, and temporary femoral arteriovenous fistula were carried out routinly. Result Operations were successful in 157 cases(70 cases in Fogarty group, 52 in ATD group,35 in Acolysis ultrasound ablation group), and failed in 14 cases (3 cases in Fogarty group, 3 in ATD group, 8 in Acolysis ultrasound ablation group). Permanent,retrievable and temporary vena cava filters were placed in 51,32 and 88 cases respectively. Stenosis or occulsions of the iliac vein was found in 143 cases and stents were placed after balloon dilatation in 41 cases. During the operation, residual thrombi was found in 80 cases. Vessel perforation and rupture were complicated in 14 cases, thrombosis adhering in eava vein filters in 18 cases. There was no mortality and no pulmonary thromboembolism. During the follow-up, we found iliae vein restenosis in 21 cases, thrombosis recurrence in 36 cases, stents displacement in 6 cases, and stents fracture in 2 cases. Conclusion Surgical therapy is effective for DVT of the lower extremities.

ObjectiveTo investigate the effect of endovascular stent with or without coil graft on intracranial wide-necked aneurysms. Methods12 cases with intracranial wide-necked aneurysms, among whom, 10 cases were treated with stents and coils, 2 C4 aneurysms were treated with graft stent, were analyzed retrospectively. ResultsOf the 10 cases who were treated with stents and coils, 8 patients were completely occluded and other 2 patients were incompletely (>95%) occluded. 2 cases accepted graft stent were obliterated. Follow-up with angiography in 10 patients for 3～12 months revealed that all the aneurysms were completely occluded. 1 patient among them died. ConclusionEndovascular stent with or without coil graft is effective on intracranial wide-necked aneurysms.

AIM: To investigate the ameliorative effect of water extract of propolis (WEP) preconditioning on mesenteric microcirculation of rats subjected to small intestinal ischemia reperfusion (I/R). METHODS: Thirty-two male Wistar rats were randomly divided into sham, I/R and WEP (100, 200 mg/kg) preconditioning groups. Model of small intestinal I/R injury was made by clamping super mesenteric artery for 45 min followed by 120 min of reperfusion in rats. Mesenteric microcirculation was detected at the end of reperfusion. The degree of small intestinal injury was The content of soluble intercellular adhesion molecule-1 (sICAM-1) in plasma and myeloperoxidase (MPO) activity in intestinal tissue were detected using enzyme linked-immuno-sorbent assay (ELISA) and spectrophotometer, respectively. RESULTS: (1) WEP preconditioning alleviated significantly the pathologic lesion in small intestine, and wet/dry ratio, compared to those in I/R group (P<0.01). (2) The disturbance of the blood flow in microvessel induced by I/R was improved significantly by WEP. In addition, WEP preconditioning alleviated significantly the decrease in diameters of microvessels and microcirculatory blood velocity (P<0.05 vs I/R group) and inhibited the adherence of leukocytes to venule (P<0.01 vs I/R group) in a dose-dependent manner. SICAM-1 content in plasma and MPO activity in intestinal tissue were decreased in WEP preconditioning group, compared to those in I/R group (P<0.05 or P<0.01). CONCLUSION: WEP preconditioning ameliorates mesenteric microcirculation of rats subjected to small intestinal I/R through suppressing the activation of polymorphonuclear neutrophils mediated by ICAM-1.

Objective To evaluate the efficacy of endovascular interventional treatment for infrapopliteal arterial ischemic diseases. Methods Sixty patients(65 limbs)of infrapopliteal arterial isehernia of the lower extremities received pereutancotm transluminal angioplasty(PTA)and/or stents implantation from November 2004 to July 2007.The symptoms,changes of ankle/brachial index(ABI),limb salvage rate and immediate patent rate were observed. Results PTA/stenting procedure was successful in 51 out of 60 patients(65 limbs)with the technical success rate of 83.3%.Symptoms were improved in 53 cases(88.3%)including complete symptom remission in 40 cases(66.7%),partial remission in 13 patients(21.7%).The procedure failed in 7 cases(11.6%).In successful cases,AB1 increased from preoperative 0.40±0.18 to postoperative 0.91±0.22(P＜0.01).The amputation below knee was performed in two cases and toe apodizers in four cases.The limb salvage rate was 91% during the same hospitalization.Discharged 54 cases were followed up with 14.5±1.2 months,during this period amputation above knee was performed in 2 cases,amputation below knee in 2 cases,and toe apodizers in 2 cases,with a limb salvage rate of 88.9%(48/54).Symptoms were recurrent in five cases,with recurrence rate of 9.2%.Vascular reocclusion or restenosis were found in 10 cases.the patent rate was 81.5% and the cumulative patent rate was 57.3% in one year. Conclusions Endovascular interventional treatment for infrapopliteal arterial ischemic disease is safe and effective.

Objective To develop a double-antibody sandwich ELISA for determining the concentration of nucleoprotein (NP) of rabies virus in various products of rabies vaccine.Methods The purified rabies antibodies from a rabbit were used to coat microwell plates. Horseradish peroxidase-conjugated anti-NP monoclonal antibody was used to probe the NP bound to coated antibodies.The assay was used to quantitatively determine the concentration of NP of rabies virus.Results The results showed that the coefficient of linear correlation was higher than 0.97.The optimal linear range was 0.000625~0.01 IU/ml and the detection limit was 0.000625 IU/ml. The recovery rate was 102~109% and the coefficient of variation was only 7.2%~9.4%.No cross reactions were observed with bovine serum,bovine serum albumin,ovalbumin,refined solution of influenza vaccine,encephalitis B vaccine,and hepatitis A vaccine.Conclusions The results indicated that the assay is specific,sensitive,accurate,reproducible,and stable,and could be suitable for quantitative determination of different rabies vaccine's processes products.

Objective To evaluate clinical outcome of patients treated with endovascular dilation and stent placement for ilio-femoral venous postthrombotic syndrome (PTS).Methods 42 PTS cases were enrolled in our group from June 2003 to December 2011.Dilation and stent placement in stenosis/ occlusion of ilio-femoral veins were performed in all cases,temporary femoral arteriovenous fistula was established in 24 cases.Results These were not severe perioperative complications.All patients were followed up for 8-75 months.Preoperative limb ulcers in 5 cases were healed.Early thrombosis in stents found in 3 cases was cleared by catheter directed thrombolysis (CDT).Severe in-stent restenosis (＞ 50％)was found in 10 cases,treated with dialation or re-stenting.Primary patency,assisted primary patency and secondary patency rates were 75％,78％,80.1％;64.1％,67.1％,69.6％;63.8％,65.3％,66％;61.7％,65％,65.2％,respectively,at 6 months,12 months,24 months and 36 months.Postoperative Venous Clinical Severrity Score (VCSS) decreased (P =0.000).There was statistical significant improvement in every dimension evaluated by the MOS item short from health survey(SF-36) after operation (P =0.000).Conclusion Ilio-femoral venous stenting is a safe and effective treatment for PTS and with good clinical midterm results.

Objective To evaluate the prevention and management for the complications in interventional therapy for the lower extremity arteriosclerosis obliterans (ASO). Methods In this study 207 ASO cases received interventional therapy. The relationship between complication rates and different TASC type and the influence of diabetes mellitus (DM) with coronary heart disease (CHD) on critical organs complication rates was analyzed. Results The intervention succeeded in 190 cases. There was 17 failures, including 13 procedure failures and 4 deaths due to postoperative critical organ complications. Among the complications there were puncture site hemorrhage in 12, pseudoaneurysm in 4, alimentary tract hemorrhage in 2, arteriorrhexis in 6, cerebral infarction in 8, acute heart failure in 9, respiratory failure in 13, renal failure in 6, thrombosis in 5 and blue-toe syndrome in 1. The intraoperative complication rate of femoral-political type (39.84%, 51/128) was high than that of aorta-iliac type (18.99%, 15/79) (P< 0.05). Those critical organ complication rates of patients with DM and patients with DM&CHD were 27.66% (13/47)and 24.49% (12/49)respectively, they were higher than that of patients without (5%, 2/40) (P<0.05). Conclusions The high complication rates during interventional therapy of ASO were because of misoperation and complicated pathological type and together with DM and CHD. These rates could be decreased when we treated DM and CHD before operation and chosen a reasonable method and shorten the duration of operation.

This systematic review aimed to evaluate the efficacy and safety of assisted hatching (AH) performed in couples with advanced maternal age.We searched for randomized controlled trials (RCTs) in electronic databases,including MEDLINE,EMBASE and CENTRAL (from inception to January 2018);in addition,we hand-searched the reference lists of included studies and similar reviews.We included RCTs comparing AH versus no treatment (control).The meta-analysis was performed by RevMan 5.3 software.The search retrieved 943 records and 8 RCTs were included,comprising 870 cycles (n=440 for AH,and n=430 for control).There was no significant difference in the rates of live birth (RR 0.88,95％ CI 0.65 to 1.18,3 RCTs,n=427,I2=0％),clinical pregnancy (RR 1.00,95％ CI 0.83 to 1.19,8 RCTs,n=870,I2=22％),implantation (RR 1.07,95％ CI 0.83 to 1.39,4 RCTs,n=1359,I2=0％),miscarriage (RR 1.13,95％ CI 0.66 to 1.94,2 RCTs,n=116,I2=0％) and multiple pregnancy (RR 0.89,95％ CI 0.31 to 2.52,1 RCT,n=97,I2=not applicable) between the treatment group and control group.No reasonable conclusions could be drawn regarding reproductive outcomes after AH in patients with advanced maternal age due to the small sample pooled in meta-analyses.Studies of high methodological quality and with adequate power are necessary to further investigate the value of AH in assisted conception of those patients.

OBJECTIVETo study the characteristic and surgical treatment of traumatic lumbo-sacro-pelvic injuries.

METHODSA retrospective study was carried out on 8 cases with traumatic lumbo-sacro-pelvic injuries between August 2005 and February 2008, which included 6 male and 2 female, aged from 21 to 52 years with a mean age of 38.4 years. ISS scores were undertaken to evaluate the injury severity of the cases after admission. Measures were taken to treat the emergency that affected the patients' lives. After the patients' conditions were stable, lumbo-iliac fixation was performed to treat traumatic lumbo-sacro-pelvic injuries. Imaging examinations were made to observe the reduction of fracture after operation. Injury of nerve was evaluated with ASIA score, and ASIA scores of preoperation and the last follow-up were analyzed statistically with paired t test.

RESULTSThe group was followed up for 9 to 25 months, averaging 16.9 months. Postoperative imaging examinations showed satisfied reduction of fracture. The preoperative ASIA sensory score and motor score were 35.8+/-5.3 and 31.9+/-6.4 respectively, while the sensory score and motor score were 51.8+/-13.8 and 38.2+/-7.5 at the last follow-up respectively. The sensory and motor functions were improved significantly after operation (P<0.01). The functions of urination and defecation of 6 cases were recovered for different degree after operation. In all of the cases, no aggravated injury of nerve occurred.

CONCLUSIONSTraumatic lumbo-sacro-pelvic injuries is a kind of severe injury of lumbo-sacro-pelvic region. It can be treated with lumbo-iliac internal fixation and fine clinical effect can be gained.

OBJECTIVETo observe the therapeutic effect of modified Longdan Xiegan Decoction (LXD) on hyperandrogenism in patients with polycystic ovary syndrome (POS) of stagnant fire in Gan channel type.

METHODSForty-eight patients were divided into two groups: the LXD group (25 cases) treated with LXI) for 3 months, and the Diane-35 group (23 cases) with Diane-35. Condition of menstruation, acne, hairiness were observed, basal body temperature (BBT) was measured, and the serum levels of luteinizing hormone (LH), follicle-stimulating hormone (FSH), prolactin (PRL), free testosterone (FT), and androstenedione (A) were detected before and after 3 months' treatment. Meanwhile, adverse reaction was observed.

RESULTSAfter treatment, the condition of menstrual disorder, acne and single-phase BBT were improved significantly, and serum levels of LH, LH/FSH, FT and A decreased in both groups (P < 0.05), showed insignificant difference between them (P > 0.05). The PRL level dropped in the LXD group (P < 0.05), which significantly lower than that in the Diane-35 group (P < 0.05). There were 3 cases with adverse reaction of irregular colporrhagia and 5 cases with nausea and vomiting in the Diane-35 group, while no adverse reaction in the LXD group occurred.

CONCLUSIONModified LXD could significantly improve the condition in hyperandrogenism patients with POS of stagnant fire in Gan channel type.
