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 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

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 describe the clinical and muscle pathological characters of juvenile myositis patients with perifascicular atrophy (PFA).Methods A series of 21 consecutive muscle biopsies with clinically and pathologically confirmed juvenile myositis were studied.All biopsies had PFA of muscle fibers.Results Clinical manifestation:11/21 had typical dermatomyositis rash,9/21 possible dermatomyositis because of atypical rash,1/21 mixed connective tissue disease;9/21 had weakness complaint;9/21with normal creatine kinase (CK) level,4/21 low grade rise,8/21 apparently elevated,10/ 11 definite dermatomyositis patients with normal or low grade level;6/21 combined with interstitial lung disease,2 with EB virus infection,1 with cytomegalo virus infection.Muscle pathology:4 specimens with atypical PFA also had enzyme abnormality in nicotinamide adenine dinucleotide,succinate dehydrogenase and cytochrome c oxidase staining,9/12 cases had membrane attack complement deposition intramuscular capillaries,and they had prominent regional mitochondrial abnormalities,protrude PFA and focal muscle damage.Skin biopsy of one case showed perivasculitis in dermis.Conclusions PFA could be seen in juvenile dermatomyositis and mixed connective tissue disease,and PFA could not increase the CK level.The capillary and intermediate-sized vessels damage may cause chronic ischemia,which could explain the PFA with mitochondrial abnormalities.

Aim To construct p27kip1 eukaryotic expression plasmid to investigate its influence on mononuclear cell proliferation and cell cycle for further researching the role of p27kip1 in disease prevention and treatment.Methods p27kip1 gene was cloned into pcDNA3.0 eukaryotic expression,then pcDNA3.0/p27kip1 mediated by liposome was transfected into mononuclear cell.MTT assay and flow cytometry were used to analyze cell proliferation and cell cycle.Results The mouse pcDNA3.0/p27kip1 eukaryotic expression plasmid were successfully constructed.The cells transfected with pcDNA3.0/p27kip1 expressed more p27 protein,and their proliferation was inhibited obviously.The percentage of the cells in G0/G1 phase increased,and that in S phase decreased significantly.Conclusions Mouse pcDNA3.0/p27kip1 eukaryotic expression plasmid could be expressed in mononuclear cells,and overexpression of p27 protein could inhibit mononuclear cell proliferation by restricting the cell cycle,making cell cycle arrest in G0/G1 phase.
