Objective To study the relationship between the expression of MAGE-10 genes and the clinical parameters of metastasis and recurrence of patients with Hepatocellular carainama (HCC). Methods The expression of MAGE-10 genes in tumor tissues,liver tissues adjacent to tumor and hepatocirrhosis tissues was examined by RT-PCR method.The relationship between positive expression rate of MAGE-10 genes and clinical parameters of metastasis and recurrence (such as AFP, AFU, Anti-HCV, HBsAg, AFPmRNA, diameter of tumor) in patients with HCC were studied. Results The positive expression rate of MAGE-10 genes significantly higher in tumor tissues than that in the surrounding tumor tissues (51 6% vs. 0%, ? 2=18 95,P 0 05).There was no expression of MAGE-10 in hepatocirrhosis tissues of 10 cases. Conclusions There was a high frequency of MAGE-10 genes expression in HCC,but it is unrelated to the tumor markers,metastasis and recurrence of HCC.

Acute ischemic stroke is a common disease serevely threatening the public health. The main management involves intravenous thrombolysis, intra-arterial thrombolysis and mechanical embolectomy. Recently, endovascular mechanical embolectomy is attracted more attention because it provides a good outcome for patients either ineligible not responsible for IV thrombolytic therapy. The article reviews the relative aspects with summerization in this field.

Objective To summarize the therapeutic efficacy of electrocoagulation for varicose veins of the lower extremities.Methods Totally 168 cases(238 limbs)of varicose veins of the lower extremities were treated with electrocoagulation in our department from April 2000 to April 2007.Through a small ankle incision,electrocoagulation probe was inserted ascendingly into the groin via the great saphenous vein.After high ligation of the great saphenous vein,the varicose veins and great saphenous trunk were electrocoagulated.Results The patients were discharged from hospital in one to two days after the operation.None of them had incisional infection.The ulcers at the ankle were healed in four weeks.Postoperative complications in this series,included Ⅰ degree burn injury in one limb,Ⅱ degree burn injury in one limb,superficial phlebitic pain in two limbs(two cases);and numbness around the ankle in 14 limbs(10 cases).Totally 148 cases with 208 limbs were followed up for 2 to 9 years with a mean of 6.6 years.During the period,the rate of recurrent varicosity was 3.4%(7/208);and healing rates of ache,dermatitis and eczema,ankle pigment,swelling around the calf and ankle were 95.3%(162/170),85.7%(12/14),41.7%(15/36)and 36.4%(16/44)respectively.Conclusion Electrocoagulation is a minimally invasive and effective method for the treatment of varicose veins of the lower extremities,with quick recovery and low rate of recurrence.

Objective To investigate the effects of low-dose ketamine combined with fentanyl or sulfentanyl in postoperative patient-controlled intravenous analgesia.Methods Two hundred cases with ASA Ⅰ~Ⅱ undergoing elective orthopedic operations were randomly allocated into four groups(50 cases for each group): 0.4?g/(kg?h) fentanyl(group F);0.2?g/(kg?h) fentanyl+120?g/(kg?h) ketamine(group FK);0.04?g/(kg?h) sulfentanyl(group S);and 0.02?g/(kg?h) sulfentanyl+120 ?g/(kg?h) ketamine(group SK).8mg of ondansetron was added to each recipe,and then diluted into 100ml with normal saline.The loading doses of all the patient-controlled-analgesics were 2ml administered 30min before the end of the operation.The background infusion doses were 2ml/h,while the pressing doses were 2ml,with intervals of 30min.Heart rate(HR),blood pressure(BP),respiration rate(RR),pulse O2 saturation and visual analogue scales(VAS),sedation score(SS) with adverse effects and the total times of pressing PCA pump button were observed and recorded in all patients respectively for 48h after operations.Results No statistically significant differences were found in HR,BP and RR among the four groups.VAS and the total pressing times in group F were higher than that in the other groups significantly(P

Objective To evaluate the influence of different combination of anesthetics on blood pressure (BP) and heart rate (HR) of aged patients with serious illness during operation. Methods Forty patients, aged 80~92, with physical status Ⅱ~Ⅲ as categorized according to American Society of Anesthesiologists (ASA) undergoing selective surgery, were randomly divided equally into two groups: in group A ancsthesia was induced with midazolam, fentanyl and maintained with isoflurane, and in group B anesthesia was induced and maintained with etomidate, sevoflurane and nitrous oxide. Mean arterial pressure (MAP), HR and bispectral index (BIS) were observed at the points of preinduction (T0), induction (T1), intubation (T2), incision (T3), 30 minutes after incision (T4) and extubation (T5). Results After induction, BIS decreased from 95?2 to 52?4, while MAP and HR decreased from 110?11mmHg and 73?8/min to 75?9mmHg and 59?4/min respectively, in group A. While in group B BIS decreased from 94?3 to 58?3, MAP and HR decreased from 103?8 mmHg and 76?6/min to 87?7 mmHg and 67?5/min, respectively. At the point of tracheal intubation, MAP and HR increased significantly in group A compared with group B (P

ObjectiveTo investigate the clinical and pathological characteristics of dermatomyositis with muscular perifascicular atrophy (PFA).MethodsA series of 104 consecutive patients clinically and pathologically diagnosed as dermatomyositis by muscle biopsy in our laboratory from December,2003 to August,2011,were enrolled in this study. Muscle biopsy of all the enrolled patients had shown PFA of muscle fibers.ResultsAmong the 104 patients,34 were males and 70 were females with a mean age of 45 years old.Among them,8 cases had normal electromyogram;42 had normal serum creatine kinase level;11 were diagnosed as carcinoma;75 were found to be combined with interstitial lung disease (ILD).Based on morphologic changes of muscle biopsy,they were divided into pure PFA group with 54 cases and PFA plus focal damage group with 50 cases.Compared with the pure PFA group,there was prominent mononuclear cell infiltration into perimysial intermediate sized vessels and membrane attack complement (MAC) deposition in the intramuscular capillaries in the PFA plus group.Skin biopsy had been taken in 12 cases together with muscle biopsy and had shown the border effectof both PFA and interface dermatitis in muscle and skin.ConclusionsOur study suggests that chronic immune vascular damage and insufficiency in dermatomyositis may cause ischemia and focal myofiber damage in watershed regions. The incidence of ILD in our dermatomyositis patients with PFA is high.

Objective To investigate the change of renal tubular function in elderly patients after use of β lactam antibiotic. Methods The elderly patients with pulmonary infection were treated with β lactam antibiotic,the dosage was 50%-70% of normal use. The renal tubular function indicated by urine α1-MG, β2-MG, pro/Cre, NAG/Cre and glomerulus function marked by eGFR, serum creatinine (Cre)), cystatin C were detected during drugs treatment and 7 days after stopping medications. Results The infection was controlled well in 3-7 days after treatment. Urine α1-MG, β2-MG, pro/Cre and NAG/Cre were abnormal before treatment, were elevated in 3, 14 days after using antibiotic, and came down to the level before treatment on 7 days after stopping treatment. The level of Cre and eGFR was (89.0±25.97) μmol/L and (26.39±8.17) ml/min before treatment, then elevated and decreased in 14 days after treatment, respectively, and down to the level before treatment on 7 days after stopping of antibiotic. Cystatin c was abnormal before treatment and did not change significantly after treatment and after stopping antibiotic. Conclusions It is important to protect renal tubular function and to adjust antibiotic dosage according to eGFR during using antibiotic in elderly patients to control infection.

Objective To investigate the clinical value of MRI in evaluating the cardiac structures and function of congenital heart diseases.Methods Fifteen cases with surgically proved different types of CHD were examined by the techniques of magnetic resonance imaging ( MRI) and echocardiography (ECG).The results were compared to determine their values in showing the abnormalities of cardiac structures and function.Results In 15 cases,20 malformations were diagnosed correctly by MRI within 24 abnormalities confirmed by operation(20/24),21 by ECG (21/24).MRI was better than ECG in displaying great vascular diseases, while ECG was better in valvular diseases.There was no significant difference between MRI and ECG in examining cardiac function.Conclusion MRI can clearly show the abnormalities of cardiac anatomy and function.
