Objective To compare the effects of the two kinds of crystalloid solutions on glycometabolism in type 2 diabetic patients during the operation for the sclestion of the most suitable crystalloid solution. Methods In the forty scheduled gastrointestinal operation patients,there were twenty (D-group) type 2 diabetic patients and the others (N-group) were non-diabetic patients. Each of the two groups were randomly divided into two groups according to infusing different crystalloid solutions: lactated Ringer’s solution (L group), Plasma Lyte A (A group).So the patients were divided into D-L group,D-A group,N-Lgroup,N-A group.The blood glucose concentration,the blood lactate concentration and artery blood gas analysis before operation (T0) and at the end of operation(T1)were measured . Results The blood glucose concentrations had significant increase at the end of operations,and the blood glucose concentrations of D group were higher than that of N group at T0 and T1.The lactate concentrations before operation were normal in all the patients, but the lactate concentrations were over the normal limits after infusing lactated Ringer’s solution and remained normal after infusing Plasma Lyte A.The lactate concentrations had significant increase in the other three groups except N-A group. Conclusion Plasma Lyte A is the more safe and efficient crystalloid solution for diabetic patients during the operation.

Objective To discuss the efficacy of laparoscopy combined with uterine aspiration for tubal interstitial pregnancy and cornual pregnancy. Methods From January 2004 to January 2007,laparoscopy combined with the preservation of the oviducts was performed on 56 patients with tubal interstitial pregnancy or cornual pregnancy. During the operation,the ectopic pregnancy tissues were removed,and then uterine aspiration was carried out. Results The operation was completed in all of the cases without conversion to open surgery. One of the patients showed persistent ectopic pregnancy,and was cured by muscular injection of MTX injection. In this series,the rate of oviduct patency was 33.9% (19/ 56); 18 moths after the operation,the uterine pregnancy rate was 71.4% (40/56),ectopic pregnancy rate was 16.1%(9/56),and the secondary infertility rate was 1.2% (7/56). Conclusions It is safe and effective to treat tubal interstitial pregnancy or cornual pregnancy with laparoscopic operation combined with uterine aspiration.

Objective To screen the microsatellites with low occurrence rate of stutter band and establish the effective bovine STR typing system.Methods The tetranucleotide STR loci in bovine genome were searched with Tandem Repeat Finder software.Primers were designed and used to amplify these candidate loci and the PCR products were separated with electrophoresis.DNA samples from 100 head of unrelated cattle were typed.Results Among these candidate loci,6 bovine tetranucleotide STR loci showed high polymorphism,and their CDP and CPE value were 0.99995 and 0.859591 respectively.Conclusion The 6 bovine tetranucleotide STR loci can be used for bovine identification and parentage testing.

Objective To observe efficacy and safety of 2 ways of intravenous anesthesia in endoscopic mucosal resection (EMR) for early esophageal cancer and its precancerous lesion.Methods A total of 140 patients with early esophageal cancer and its precancerous lesion undergoing EMR were enrolled and randomized into 2 groups, with 70 patients in each.Midazolam and propofol were used for group Ⅰ, while midazolam and etomidate were used for group Ⅱ.Vital signs, anesthetic effect, recovery time during the therapy, intra-operative and post-operative adverse reactions were compared.Results Anesthesia with both methods could reach the need for safe EMR.The blood pressure and heart rate of patients in group Ⅰ significantly decreased during the therapy, while no significant difference was found in those of group Ⅱ, but which was significantly different from those of group Ⅰ at some parts of the observation point (P＜0.05).Pulse oxygen saturation of all patients during the procedure was within normal range.No significant difference was found between 2 groups in recovery time.The incidence of muscle tremor or myoclonus in group Ⅱ was significantly higher than that of group Ⅰ, but the incidence of bradycardia and hypotension in group Ⅱ was lower than that of group Ⅰ (P＜0.05).Several patients complained pain, nausea and dizziness after therapy, but there was no significant difference between two groups. Conclusion Anesthesia with propofol and etomidate can both be applied to digestive endoscopy.Etomidate shows advantages in more stable hemodynamics.

Purpose To investigate the expression and significance of MCM5 and p16INK4A in cervical carcinoma and cervical intraepithelial neoplasia (CIN 1,CIN 2 ～ 3) with different degrees of HPV 16 infection.Method RT-PCR and immunohistochemistryof SABC method were used to detect the expression of mRNA and protein in HPV 16 infected normal cervix,CIN 1 tissue,CIN 2 ～3 tissue and cervical squamous cell carcinoma and analyzed the clinical significance.Result The expression of p16INK4A and MCM5 mRNA in cervical cancer tissues were significantly higher than that in normal tissues (x2 =-6.589,P ＜0.001,x2 =-4.349,P ＜0.001).The degree of cervical lesions increased gradually (x2 =57.141,P ＜ 0.001,x2 =47.628,P ＜0.01).Expression of mRNA MCM5 was correlated with pathological grade and clinical stage.Ⅰ a-Ⅰ b period was significantly lower than that of Ⅱ a-Ⅱ b (x2 =-4.93,P ＜0.01),the expression decreased with the decrease of pathological grade (x2 =-4.017,P ＜0.01).The expression of p16INK4A mRNA in cervical cancer decreased with the decrease of pathological grade (x2 =8.560,P ＜ 0.01).The most obvious expression of p16INK4A and p16INK4A mRNA in squamous cell carcinoma.Expression of MCM5 protein and p16INK4A protein in cervical squamous cell carcinoma was positively correlated (r =0.497).Conclusion There is high expression of MCM5 and p16INK4A in cervical carcinoma.MCM5 can be a better reaction of cervical malignant hyperplasia,and p16INK4A joint detection for the improvement of CIN classification and prognosis of the significance of the judgment.

Objective To evaluate whether glucose is associated with thrombolysis in myocardial infarction (TIMI) flow before primary percutaneous coronary intervention (PCI).Methods Pre-operation blood glucose level, TIMI flow and baseline characteristics of 120 consecutive acute ST-segment elevation myocardial infarction (STEMI) patients treated with primary PCI were analyzed. Hyperglycemia was defined as whole blood glucose ≥7.8 mmol/L (140 mg/dL). Results Only 18 patients (15%) had TIMI 3 flow before primary PCI and hyperglycemia was observed in 87 patients (72.5%). TIMI grade 3 flow were more commonly found in the normoglycemia group compared with the hyperglycemia group before primary PCI (27.3% vs 10.3%,P
