Objective To investigate effect of sorafenib on serum hepatoma marker in patients with advanced hepatocellular carcinoma. Methods 101 patients with advanced hepatocellular carcinoma were selected, and divided into two groups.50 cases in control group were treated with routine clinical treatment, and 51 cases in experimental group were treated with sorafenib on the basis of control group.The survival time, adverse reactions, VEGF, CTGF, HIF-1 and OPN levels were compared after the treatment.Results The survival time of experimental group was higher than control group (P<0.05).Compared with control group, the serum levels of VEGF、CTGF,HIF-1, OPN,AFP, CEA, and CA199 in experiment group were lower (P<0.05,P <0.01).There were no significant differences of total adverse reactions between experimental group and control group. Conclusion Sorafenib can effectively prolong survival time of patients with advanced hepatocellular carcinoma, reduce serum VEGF, CTGF, HIF-1 alpha and OPN levels.

Objective To study the relationship of expression of angiopoietin gene and angiogenesis in the in-situ implanted hepatoma in rats. Methods Forty Wistar rats were used to establish the in-situ implanted hepatoma model by implanting Walker256 hepatoma cell line. The number of microvessel density(MVD) in hepatoma was calculated . The expression of angiopoietin mRNA was observed by in-situ hybridization method. Results The MDV in the implanted hepatoma in the first day of 1, 2 and 3 week postimplantatively were (15?4.3)/Hp,(17?3.6)/Hp,(45?7.8)/Hp respectively. The amount of MDV and expression of Ang-1 mRNA were increased significantly and correlated with MDV in the hepatoma tissues and non-hepatoma tissues,and no significant difference between the two types of tissues. Expression of Ang-2 mRNA was not seen in non-hepatoma tissues,but in hepatoma tissues,the expression of Ang-2 was obvious. Conclusions Angiopoietin-2 mRNA may play a role in the angiogenesis of the in-situ implanted hepatoma.

Objective To analyse the clinical features in general paresis of insane(GPI)as to offering an early diagnosis. Methods A retrospective analysis of 2 cases of GPI was focused on their clinical manifestations. Results The clinical features of GPI showed: (1) Chronic onset, progressive development in 2 cases; (2) Dementia was key symptom.Hasegawa dementia scales were 4 and 17 in 2 cases.2 cases accompanied with abnormal mentality,such as delusion of grandeur ,euphoria and so on;(3)GPI have features of pupil change,dysarthria,muscular tension,abnormal reflection; (4) Serum and cerebrospinal fluid (CSF) syphilis antibody reaction manifested positive, CSF protein content was increased significantly, and cells increased ( with lymph cell mainly ); (5) Head MRI manifested: cerebral atrophy in 2 cases, multiple abnormal signals in cerebral parenchyma in 1 case. Conclusions GPI misdiagnosis rate is high. Important basis of diagnosis remains on clinical manifestations, laboratory and imaging examinations.

Objective To analyze complications of carotid artery stenting (CAS) and preventions.Methods Clinical data and treatment outcomes of 72 consecutive patients ( 80 stents ) from July 2006 to January 2012 with carotid stenosis were analyzed.Asprin 100 mg and clopedigrel 75 mg were given orally 5 days before CAS.Distal embolic protection device were implanted in all patients,pre-dilatation was done for those with carotid stenosis ＞ 90％ and post-dilatation was done for those of residual stenesis ＞ 30％.Severe complications of CAS mean death,myocardial infarction (MI) and stroke.Other minom included transient ischemic attack ( TIA ),hyperperfusion and intracranial hemorrhage ( ICH ),bradycardia and/or hypotension,hypertension,access hematoma or bleeding.Results In 72 patients a total of 80 self-expandable bare stents were successfully implanted.Distal embolic protection devices were used in all cases.Combined procedure was taken in 5 cases including OPCABG in 2 cases,left subclavain artery stenting in 2 cases and renal artery stenting in 1 case.The overall in-hospital complications was 37.5％ (27 of 72).Of these events,1 case had minor strokes defined as a modified Rankin Scale score less than 3 at 1-year follow-up,2 patients (2.78％ ) experienced a hemispheric TIA (neurological symptoms that resolved within 24 hours),1 patient experienced hyperperfusion syndrome.The overall mortality rate was 0,21 cases (29.2％ ) experienced hemodynamic instability (hypotension in 15 cases,bradycardia in 5 cases and hypertension in 1 case) and 2 others had access hematoms.The 30-day death/stroke/myocardial infarction risk was 1.39％ (1 minor stroke).Conclusions Hemedynamic instability (hypotension and bredycardia) is main complications of carotid artery stenting in patients with carotid artery stenosis,severe complications are rare.

Objective To investigate the associations of aquaporin-4 (AQP4) promoter polymorphisms with anti-AQP4 antibody and genetic susceptibility to multiple sclerosis (MS) and neuromyelitis optica (NMO) in Southern Chinese population.Methods The polymorphisms of AQP4promoter 0 and 1 were analyzed by PCR and DNA sequencing in 18 NMO,38 MS,13 recurrent myelitis (RM),6 recurrent optic neuritis (RON)patients and 39 healthy controls. Results Fourteen polymorphism loci were observed in AQP4-promoter 0,while 6 ones were observed in AQP4-promoter 1.Among them,the incidence rate of polymorphism at position - 1003 bp (A-G) of AQP4-promoter 0 in anti-AQP4 antibody-positive patients was significantly higher than that in anti-AQP4 antibody-negative patients and controls (former:13/18 vs 20/45,P =0.046; latter:13/18 vs 10/39,P =0.001 ).The incidence rates of polymorphism at position between -401 bp and -400 bp ( C inserted) of AQP4-promoter 1 in anti-AQP4 antibody-positive and -negative patients were significantly higher than that in controls( former:5/16 vs 0/28,P =0.008; latter:8/38 vs 0/28,P =0.027 ). The incidence rates of polymorphism at position - 1003 bp (A-G) of AQP4-promoter 0 and position between -401 bp and -400 bp ( C inserted)of AQP4-promoter 1 in patients with NMO and MS were significantly higher than that in controls( NMO:11/18 vs 10/39,P =0.010;4/15 vs 0/28,P =0.020; MS:19/38 vs 10/39,P =0.027;8/34 vs 0/28,P =0.018).Conclusions Polymorphisms loci were observed in AQP4-promoter 0 and AQP4-promoter 1,which may have an influence on the susceptibility to MS and NMO.Polymorphism at position - 1003 bp ( A-G) of AQP4-promoter 0 may be related to the emergence of anti-AQP4 antibody in patients with NMO and MS.

Effects of traditional Chinese medicine salvianolate combined with alprostadil and reduced glutathione on delay of progression in patients with acute kidney injury has been confirmed, but the role of this combination therapy on the progression of chronic renal failure is uncertain.

OBJECTIVE: To evaluate the effect of integrated traditional Chinese and Western medicine therapy on the progression of acute renal failure in patients with chronic renal insufficiency. METHODS: Thirty-two patients with chronic renal insufficiency developed acute renal failure recently were treated with Chinese herbs and western drugs intravenously and clysterizing of Chinese herbs liquid for 30 minutes, and the treatment course was 14 days. Assessment of liver and renal function, blood routine, electrolytes and endogenous creatinine clearance rate (Ccr) was performed before and 2 weeks after the treatment. RESULTS: The levels of hemoglobin (HB), white blood cell count (WBC) and serum electrolytes showed no significant changes after the treatment. The levels of blood urea nitrogen (BUN) and serum creatinine (SCr) decreased, while the level of Ccr increased significantly (P<0.05) after the treatment. The total effective rate was 65.6%. CONCLUSION: The integrated traditional Chinese and Western medicine therapy can effectively delay the deterioration of renal function in patients with chronic renal insufficiency accompanied by acute renal failure.

Objective To summarize the etiologic factors and evaluate the clinical outcome of reoperations on 119 limbs of recurrent varicose veins.Methods Retrospective analysis was made on etiologic factors of 119 limbs (113 patients) of recurrent varicose veins admitted to our hospital from January 2007 to June 2013.All patients underwent color duplex ultrasonography and anterograde venography of the lower extremity and were treated by reoperations.Results In the 119 limbs,102 limbs (85.7％) had residual main great saphenous veins or tributaries,97 limbs (81.5％) had incompetent perforator veins,23 limbs (19.3％) had neovascularization,9 limbs (7.6％) had incompetent small saphenous veins,21 limbs (17.6％) had incompetent femoral veins,6 limbs (5.0％) had iliac vein compression syndrome,and Budd Chiari syndrome was found as the cause of recurrence in 1 limb (0.8％).Postoperative patients were followed-up for 6-72 m (32-± 7 m).The cure rate of varicose veins were 100％.There was not recurrence of varicose veins,postoperative VCSS was 0-5 (1.2 ±0.5) vs preoperative 1-17 (6.2 ±2.5)(P ＜ 0.01).Conclusions Residual and incompetent great saphenous veins or tributaries and incompetent perforator veins were the main etiologic factors of postoperative recurrent varicose veins.Therapeutic principle for recurrent varicose veins is to eliminating the reverse flow of superficial vein system and ligate incompetent perforator veins.

Objective To evaluate carotid endarterectomy (CEA) for bilateral moderate to severe carotid stenosis.Methods The clinical data of 59 patients with bilateral moderate to severe carotid stenosis who were treated with CEA in our hospital from October 2010 to August 2014 were retrospectively analyzed.There were 50 males and 9 females age ranging 42-80 years (mean:65 ± 9 years).48 patientsunderwent ipsilateral CEA and 11 underwent staged bilateral CEA.In patients who were confirmed to have coronary artery disease or peripheral vascular disease by preoperative angiography,6 received coronary artery bypass graft (CABG)simultaneously,1 received iliac artery balloon angioplasty and stent implantation simultaneously,and 1 received renal artery stenting simultaneously.Results A total of 70 endarterectomies were performed,shunt and patching were used in all patients,the surgical success rate was 100％.2 patients suffered from vagus nerve injury,4 patients suffered from hypoglossal nerve injury,and 3 patients presented with hyperperfusion syndrome.Follow-up period was 2-36 months (mean:19 ± 10 months).1 patient died of heart attack during the follow-up,the other patients were relatively stable with no restenosis.Conclusion CEA should be performed in patients with bilateral moderate to severe carotid stenosis,and the prognosis is good.

The clinical data of 21 patients with carotid body tumor (CBT) were analyzed retrospectively.The lesions were unilateral (n =20) and bilateral (n =1).Among 20 surgical cases, the procedures included tumor resection alone (n =11) , tumor resection along with external carotid artery (n =6) and vascular reconstruction of carotid artery after resection of tumor body (n =3).No mortality occurred during perioperative period.CBT was confirmed by pathologic examination in all cases and 1 case was malignant.Follow-up period ranged from 3 months to 7 years and the follow-up rate was 85％.Five cases of cranial nerve impairment recovered completely over 3 months.One case of bilateral CBT underwent contralateral tumor resection at another hospital 1 year later and 1 case with malignant tumor died from metastases 3 years later.The remainder survived recurrence-free.CBT tends to be misdiagnosed.Therefore ultrasonography, digital subtraction angiography (DSA), CT angiography (CTA) or magnetic resonance angiography (MRA) are important for preoperative diagnosis and evaluation.Surgical resection is a first choice for CBT.
