Objective To compare safety,completeness and long-term results between lobectomy by video-assisted thoracoscopic surgery(VATS) and thoracotomy for clinical stage Ⅰ / Ⅱ non-small cell lung cancer(NSCLC).Methods Between July 2010 and December 2011,673 patients with clinical stage Ⅰ / Ⅱ NSCLC from 11 hospitals underwent pulmonary lobectomy(425 VATS,248 thoracotomy).Patients were matched by propensity score matoh method to create two comparable groups,402 patients remained eligible for analysis,with 201 patients in each group.Perioperative variables and follow-up results were compared between the two groups.Results Patients characteristics were comparable between the two groups,except for a slight lower preoperative FEV1,FEV1% and FEV1/FVC in the VATS group (P < 0.05).There was one postoperative death in each group.There was no significant difference in operative time,mediastinal lymph nodes stations/numbers dissected and postoperative drainage time between the two groups.The operative blood loss was lower in the VATS group(P < 0.001),the mean hospital stay was shorter in the VATS group(P < 0.001).Postoperative pneumonia/pulmonary atelectasis rate was lower in the VATS group than in the thoracotomy group (5.1% vs.10.4%,P < 0.05).Median follow-up time was 20 months in both groups.One-year and two-year recurrence-free survival was 90% vs.88% and 80% vs.70%,respectively(P =0.163).One-year and two-year overall survival were 96% vs.95% and 88% vs.85%,respectively(P =0.226).Conclusion For clinical stage Ⅰ / Ⅱ NSCLC,VATS lobectomy is a feasible procedure with shorter hospital stay and less complications,while its surgical and oncologic outcome is comparable to that of thoracotomy lobectomy.

Two patients with neonatal diabetes tested as V59A and V59M mutations were chosen for the study. Clinical data were analyzed retrospectively. The results showed that the patient with V59A mutation was characteristic of spasm and hyperglycemia at the age of three month, and treated with insulin for a long time as unresponsive to the glibenclamide at the beginning. Myasthenia and delay of development were observed during the follow-up. At the age of two years, glibenclamide was tried for the second time with a high dose and fairly-controlled glucose level. The patient with V59M mutation was diagnosed with diarrhea, hyperglycemia, and ketosis at the age of two month, and was responsive to glibenclamide at a relatively low dose with well-controlled glucose level. These results suggest that KCNJ11 V59M mutation would show some milder clinical manifestations and better glibenclamide efficacy as compared with V59A mutation.

Objective To observe the efficacy of pregabalin in the treatment of painful diabeticperipheral neuropathy.Methods In a 8-week study,50 patients were randomly assigned into two groups:the therapy group and the control group.The patients in the therapy group were treated with pregabalin 150 mg/d,and the patients in the control group were treated with carbamazepine 200 mg/d.The dose of pregabalin was increased to 300 mg/d till pain was alleviated in the therapy group,and the dose of carbamazepine was increased to 600 mg/d till pain was alleviated in the control group.The therapeutic effect and VAS score in the two groups were observed and evaluated.Results After 1 and 8 weeks' treatment,the therapeutic effect of therapy group were significantly superior to the control group ( At 1 week:U =2.028,P =0.046 ; At 8 week:U =3.540,P <0.001 ).After 1 and 8 weeks' treatment,the VAS scores of therapy group were significantly lower than the control group ( At 1 week:5.13 ± 1.76 vs.6.74 ± 1.52,P < 0.05 ; At 8 week:1.13 ± 0.45 vs 3.27 ± 1.04,P < 0.05).There were 5 patients (20%) and 10 patients (40%) had adverse reaction in the therapy and the control groups respectively.Conclusion Pregabalin is effective and safe for the treatment of painful diabetic peripheral neuropathy.

Data is the basis and soul of clinical trials. To obtain accurate data, strict and standard data management is essential, which can be effectively supported by quality control in statistical analysis. In this paper, we briefly introduce the concept of the quality control in clinical trials, and describe its contents and methods. We hope that this work will be helpful to the application of statistical quality control in data management of clinical trials.

Objective To investigate the prevalence and spectrum of β-thalassemia mutations in C, uangdong province, and provide a reference for prenatal diagnosis and genetic counseling in this population. Methods Three thousand two hundred and forty-seven blood samples were randomly selected from Guangzhou and 2984 blood samples from Shenzhen from January in 2005 to January in 2009. PCR and reverse dot blot hybridization (RDB) were adopted for detection of β-thalassemia mutations in Guangzhou and Shenzhen city. Results Seven hundred and fifty-one individuals in Guangzhou were found to have β-hemoglobin gene mutations, the detection rate was 23.13%(751/3247); 10 different mutations were identified, namely CD41-42(-TCTT), IVS-Ⅱ-654(C→T), -28(A→G), CDI7(A→T), CD71-72(+A), 13E, IVS-I-1(G→T), CD43(G→T), -29(A→G), CDI4-15(+G), which accounted for 42.53% (336/790) ,25.19% (199/790), 12.66% (100/790), 10.89% (86/790) ,3.29% (26/790), 2.15%(17/790), 1.27%( 10/790), 1.14%(9/790) ,0.51%(4/790) ,0.38%(3/790), respectively; the most common mutation was CD41-42(-TCTT), which accounted for 42.53%(336/790). In Shenzhen, 179 individuals were found to have β-thalassemia mutations, the detection rate was 6.00% (179/2984); 8 different mutations were identified excluding CD43 (G→T) and CD14-15 (+G); the most common mutation, however, was IVS-lI--654(C→T), which accounted for 40.44% (74/183). Conclusions The β-thalassemia mutations in Guangdong province are not only frequent, but also obviously heterogeneous, and the mutations differ from region to region. CD41-42 (-TCTT),ⅣS-Ⅱ-654(C→T), -28(A→G), CD17(A→T) were the 4 predominant mutations.

OBJECTIVE To investigate the clinical distribution and resistance of Acinetobacter baumannii.METHODS The bacteria were identified by BioMerieux VITEK32.Susceptibility was tested by Kirby-Bauer method.RESULTS Among specimens from which A.baumannii was examined,sputum accounted for 78.64%,secretion(9.62%)and urine(6.81%).A.baumannii was mainly distributed at ICU ward(29.58%)and then was respiratory ward(21.36%).The resistance of A.baumannii was serious.The antibiotic drugs which had the low resistance were ?-lactam/?-lactamase inhibitor combinations such as sulperazone(22.14%)and carbapenems such as meropenem(32.95%),imipenem(33.04%),and so on.CONCLUSIONS The infecton of multi-drug resistant A.baumannii has increasing tendency.Therefore monitoring A.baumannii constantly and regularly,finding out resistant strains timely and adjusting the treatment methods are very important for the prevention of nosocomial infection.

Objective Comparing the effects of steam sterilization on cyclic fatigue of stainless steel files. Meth-ods Fifty instruments of 25# stainless steel K files were randomly divided into 5 groups, which include 10 in each group. Group 1 was the blank control group, group 2 to 5 were subjected to 1, 3, 4, 5 steam sterilization cycles, then the files were tested by a custom-made device to assess cyclic fatigue and the number of cycles of failure (NCF) was calculated. Microstruc-ture of each file’s fracture surface was analyzed by Scanning Electron microscope (SEM). Results NCF in the 5 groups were 4 345.2 ± 384.2,3 937.9 ± 645.4,3 812.9 ± 532.5,3 626.2 ± 380.0,3 625.9 ± 565.6 respectively, and the differences among 5 groups were significantly different(F=2.598, P<0.05). After 4 or 5 times of steam sterilization, cyclic fatigue de-creased if compared with that in control group (P<0.05). Fracture surface in group 1 and group 2 was tough dimple structure and large numbers of regular, deep dimples were distributed on the surface. You could also see micro cavities clearly formed by fracture;Fracture surface in group 4 was dimple structure in brittle intergranular morphology. It is characterized by the presence of thin brittle precipitates, clean and smooth crystal interface, and a great sense of polyhedral stereo. Conclusion After 4 times of steam sterilization, cyclic fatigue strength of 25# stainless steel K files declined, which possessed the poten-tial risk of fracture.
