Objective To investigate the clinical effect and safety of laparoscopy on ovarian benign tumor. Methods The data of 68 patients, underwent laparoscopic operations on ovarian benign tumor from Jan 2009 to Jan 2010, were analyzed retrospectively. Sixty eight patients underwent laparotomy were randomly enrolled as control. The operative time, the blood loss, the average admission day and the average postoperative exhaust time were compared between two groups. Results We found no significant differences in the comparation of operative time ( [ 63.60 ± 7.71 ] min vs. [ 62. 40 ± 8. 90 ] min, t = 0. 663, P ＞ 0. 05 ), while the blood loss, the average postoperative exhaust time, the average admission day of the treatment group were significantly lower in the objectives than control ( [ 68.00 ± 14. 90 ] ml vs. [ 119.00 ± 19. 60 ] ml, [ 17.30 ±2.40]h vs. [34.60 ±2.80] h, [3.90 ± 1.40] days vs. [7.70 ± 1.50] days,t =2.664, 2. 523,2.724,Ps ＜0. 05). Conclusion Laparoscopy is the first choice of method in treating ovarian benign tumor given its minimal invasion and rapid recovery.

Objective To determine the accuracy and reliability of continuous glucose monitoring system(CGMS)in intensive monitoring blood glucose level.Methods The analysis was conducted on 48 type 2 diabetes patients to compare the glucose levels of glucose meter and CGMS.Each patients received CGMS for 3 days during his/her hospitalization.The data were analyzed according to correlation coefficient analysis,mean absolute error,sensitivity and specificity.Results The mean duration of CGMS recording was(71.4?0.6)h.From the data that paired glucose readings and CGMS,the coefficients of correlation ranged from 0.79 to 0.90 and the mean absolute error ranged from 6.7% to 10.0%.The sensitivity and specificity to detect hyperglycemia were 93.15% and 95.95%,respectively.Conclusion There is a good correlation between sensor readings of interstitial fluid glucose level and capillary blood glucose readings.The results indicate that CGMS is of clinical utility as a holter-type glucose tracking device.

Objective Protein chip for mucin detection was prepared to detect the serum levels of mucin1(MUC1),mucin2(MUC2)and micin5ac(MUC5AC)of colorectal cancer patients,and to discuss the relationship between colorectal cancer and the expression of MUC1,MUC2 and MUC5AC in serum.Methods The protein chip was prepared with monoclone and polyclone antibodies for the measuement of the serum levels of MUC1,MUC2 and MUC5AC in 30 patients with colorectal cancer and 30 healthy adults as control,using the method of immuno-fluorescence.Results The serum levels of mucin and CEA in colorectal cancer group were higher than that in control group.The differences were significant between the two groups concerning MUC1(5.25?2.37 vs 3.65?1.82U/ml,P0.05).The positive expression of mucin was related with the cancer differentiation.The positive expression of MUC1 and MUC5AC was higher when cancer differentiation was low as compared with high and median differentiation,but the positive expression of MUC2 was higher in high and middle cancer differentiation.When the serum level of mucin was used as an indicator for the diagnosis of colorectal cancer,the sensibility and specificity were both higher.The sensibility and specificity of MUC1 were 82.1% and 78.1%,respectively,while of combined mucins(at least 2 in 3 mucins were positive)were 96.2% and 85.3%,respectively.Conclusion The application of protein chip for mucin detection on the measurement of serum levels of MUC1,MUC2 and MUC5AC is of higher sensibility and specificity in the diagnosis of colorectal cancer.The establishment of protein chip has provided a new approach to early diagnosis of colorectal cancer,and help estimate the prognosis.

Objective:To investigate the effect of acute myocardial infarction (AMI)-activated inflammation on adipokine imbalance and the therapeutic effects of statin.Methods:A total of 32 C57BL/6 mice were divided into 4 groups:a sham group,an AMI group,a low-dose atorvastatin [2 mg/(kg.d)] group and a high-dose atorvastatin [20 mg/(kg.d)] group.AMI models were established by surgical coronary artery ligation.Plasma levels of high sensitive C reaction protein (hs-CRP),adiponectin and resistin were measured.Adiponectin and resistin expressions were determined.In addition,mouse 3T3-L1 preadipocytes in vitro were differentiated and they were stimulated by oxidized low density lipoprotein (ox-LDL).The protein expressions of adiponectin and resistin in adipocytes were detected.The effects of atorvastatin on ox-LDL-induced adipokine imbalance in adipocytes were identified.Results:The plasma levels of hs-CRP and resistin in AMI mice were significantly increased,whereas the plasma levels of adiponectin were remarkably decreased.However,atorvastatin treatment blocked the changes in the plasma levels of hs-CRP,resistin and adiponectin in AMI mice in a dose-dependent manner.Consistent findings regarding the adipose expressions of the two adipokines were obtained.The plasma levels of hs-CRP were positively correlated with resistin but negatively with adiponectin.In vitro study,ox-LDL increased resistin protein and adiponectin expressions in adipocytes,which were dose-dependently reversed by atorvastatin.Conclusion:Inflammation activation in AMI mice leads to adipokine imbalance.Atorvastatin ameliorates the AMI-induced adipokine imbalance via anti-inflammation.

Bronchopulmonary dysplasia( BPD) is a chronic lung disease that commonly occurs in pre-term. Since the 1980s,with the advances in perinatal care,survival rate of preterm has been raised,while BPD continues to be a significant cause of morbidity and mortality for premature infants. However,the treatment effect of BPD is unsatisfactory. It is urgent to search for innovative ways to reduce the respiratory injury that caused by BPD as well as to improve the quality of life. In recent years,mesenchymal stem cells′( MSC) research has pro-vided a new way for the treatment of BPD. This review primarily summarizes the current status of the MSC ther-apies and its possible mechanism on BPD.
