Objective To retrospectively review the experience and early clinical result of carotid endarterectomy (CEA) for the treatment of symptomatic carotid artery stenosis. Method CEA was performed on 82 consecutive patients (66 males, 16 females), age ranged from 48 to 84 years (mean 68.6 years). Diagnosis was established by carotid artery Doppler ultrasonography and DSA in all patients. General anesthesia was used in 39 cases, regional anesthesia was used in 43 cases. Temporary intraluminal shunts were used in 56 patients. Results There was no surgical mortality. Postoperatively 76 patients were followed up from 4 months to 18 months. Symptoms significantly improved in 57 cases, mild improvement was achieved in 14 cases, severe postoperative complication occurred in 3 patients, including cerebral ischemia in 2 cases, intracarotid thrombosis in one. Conclusion CEA is an effective therapy for the treatment of symptomatic carotid artery stenosis.

Objective To study the clinical significance of glutathione s-transferases expression ingastric carcinoma tissues. Methods The expression of 98 gastric carcinoma was studied by means ofimmunohistochemical technique. Results The glutathione S-transferases were between 25. 0% and 88. 9%in 98 cases of gastric carcinoma. The GST-? was significantly higher in the cases of poorly differentiatedthan those of well differentiated. But it was not correlated with patient age, sex, tumor size, tumor'slocation,and lymph node metastases. Conclusion The determination of GST-? may be useful for diagnosis,prognosis and treatment of gastric carcinoma.

Objective To study the implact of tacrolimus blood concentration (Tac) after renal transplantation on blood lipid and fasting glucose (FBG) in recipients.Method The recipients who regularly given Tac + mycophenolate mofetil + prednisone after renal transplantation were chosen and those had normal preoperative levels of blood lipid and fasting glucose as subjects.The recipients were classied into high concentration group,normal concentration group and low concentration group by comparing Tac blood concentration of different postoperative periods with corresponding normal concentration range.The changes of biochemical indexes such as steady Tac valley blood concentration,blood lipid and FBG were monitored,and the differences in blood lipid and FBG levels at different periods among three concentration groups were compared.Result TG level was significantly higher (P＜0.05),and HDL-C level was significantly lower in high concentration group than in normal and low concentration groups one month after operation (P＜0.05).Three months after operation,TG and FBG levels were significantly higher in high concentration group than in normal and low concentration groups (P＜0.05 and 0.01,respectively).Six months after operation,TC,TG and FBG levels were significantly higher in high concentration group than in normal and low concentration groups (P＜0.05,0.01 and 0.05,respectively).There was no significant difference between normal and low concentration groups in various biochemical indexes at any time point (P＞0.05).Conclusion The higher blood concentration of Tac and the longer used after renal transplantation,the easier it might cause drug-induced hyperlipidemia and diabetes.

Objective To investigate se rum concentration of tumor necrosis factor(TNF)-? and its correlation with insulin resistance in pregnant women with gestational diabetes mellitus (GDM). Methods Enzyme-linked immunosorbent assay was used to measure th e fasting serum TNF-? levels of 42 women with GDM (28～39 gestational weeks), a n d 40 cases of normal pregnant women in the third trimester. Fasting plasma gluc ose, insulin, C-peptide and glycosylated hemoglobin (HbA1c) were also measured at the same time. Insulin sensitive index (ISI) was calculated. Res u lts (1)Significantly elevated serum TNF-? was found in the women w i th GDM(5.2?1.6) ng/L as compared with the healthy pregnant women in third t rimester (4.5?0.5)ng/L(P

Objective To investigate evaluation role of IP-10 level in urine of kidney transplant recipients when using rabbit anti-human T-lymphocyte immunoglobulin to treat acute cellular rejection.Methods A total of 40 patients who underwent renal transplantation and had been diagnosed as acute cellular rejection according to the results of histopathological examination were randomly divided them into IP-10 group (n =20) and serum creatinine group (Scr group,n =20).Urinary IP-10 and Scr levels were measured in time and patients then were treated with ATG,of which the doses and duration were adjusted according to IP-10 or Scr levels.We compared the total and daily ATG dosages,ATG administration period,side effects of ATG such as incidence of severe platelet and neutropenia,acute rejection during first 3 months and infection rates during first 1 year.Result The number of ATG duration is 5.35 ± 1.93 for IP-10 group versus 6.70 ± 1.75 for Scr group.We used a daily dose of 2.50 ± 0.57 mg/(kg·d) for IP-10 group and 2.77 ± 0.74 mg/(kg· d) for Scr group,a total dose of 13.40 ± 6.59 mg/kg for IP-10 group and 18.25 ± 7.35 mg/kg for Scr group.There was significance between the two group in above three outcomes (P ＜ 0.05).There was no significance in incidences of severe thrombocytopenia and neutropenia,incidences of acute rejection during first 3 months,incidences of infection during first 1 year between the two group (P ＞ 0.05).Conclusion Urine IP-10 test is effective and reliable indicators which can guide ATG usage in patients with acute rejection and reduce the ATG cost.

Objective To verify the accuracy of detecting part of biochemical markers of the new"B&G System".Methods Blood serum creatinine(SCr),urea nitrogen(BUN),serum uric acid(UA),Ca or P of the same serum example were detected by"B&G System"and Hitachi 7170S automatic biochemistry analysis instrument (7170S) respectively.Each biochemical marker was divided into two teams on the basis of measure values of 7170S, and then measure values of two methods were compared.If there were significant differences,the biochemical mark- ers's detection program of"B&G System"was corrected,and then measure values of two methods of corresponding biochemical markers were compared.Results Two methods' measure values of SCr of abnormal team,BUN of each team,SUA of each team and P of each team weren't significantly different,measure values of SCr of normal team,Ca of two teams were significantly different.After corrected"B&G System",two methods' measure values of sCr of normal team,Ca of two teams weren't significantly different.Conclusion"B&G System"through correction could accurately detect biochemical markers,and it's worth applicating in clinic.

Objective To compare the effect of titanium elastic nailing (TEN) and plating in treatment of both radius and ulna fractures in children older than 10 years.Methods This retrospective analysis comprised 38 children (50 sides) of both radius and ulna fractures treated with TEN (30sides) or plate (20 sides) between 2009 and 2014.Parameters compared between the two fixation methods were operation time,ratio of open/close reduction,time to internal fixation removal,incidence of postoperative complications,and bone union time.Anderson score was used to evaluate the treatment results.Results Operation time [(94.3 ± 39.5) min vs (120.5 ± 45.4) min],time to internal fixation removal [(210.8 ± 84.1) d vs (264.4 ± 88.9) d],and ratio of open/close reduction (20/10 vs 20/0)varied significantly between TEN and plating groups (P ＜ 0.05 or 0.01).Whereas,no statistically significant differences were noted in regard to complication rate,bone union time,and effect evaluation.Conclusion For fracture of the radius and ulna in children older than 10 years,TEN should be used for closed type without obvious displacement,but plate fixation is associated with lower incidence of fracture malunion and better outcome in treatment of open type with obvious displacement.
