Surgical resection (usually lobectomy) is considered the treatment option for individuals with stage Ⅰ and Ⅱ non-small cell lung cancer. The surgical treatment of stage Ⅰ and Ⅱ non-small cell lung cancer (NSCLC) continues to evolve in the areas of intraoperative lymph node staging (specifically the issue of lymph node dissection vs sampling), the role of sublobular resections instead of lobectomy for treatment of smaller tumors (especially peripheral carcinoma ≤2 cm in diameter), and the use of video-assisted techniques to perform anatomic lobectomy. Video-assisted thoracic surgery (VATS) lobectomy provides a minimally invasive approach for the management of early-stage lung cancer. Questions about the safety of VATS lobectomy and its adequacy as a cancer operation compared with open thoraeotomy have hindered its universal acceptance among thoracic surgeons. Evidence suggests that VATS lobectomy can be safely performed and is an adequate cancer operation for early-stage NSCLC. Recently, robots have been introduced into surgical procedures in an attempt to facilitate surgical performance. However, adequately powered well-balanced studies comparing VATS with open thoracotomy for lobectomy are lacking in the literature.

Objective To explore the association between clinical pathological characteristics and the expressions of epidermal growth factor receptor (EGFR) and protein kinase B (AKT) in gastric carcinomas.Methods The expressions of EGFR and AKT were measured with immunohistochemical method in the cancer tissues and cancer-adjacent normal tissues from 153 cases of patients with gastric cancer.The association between clinical pathological characteristics and their expressions were analyzed.Results The expressions of AKT and EGFR in gastric cancer tissues had no relationship with gender,age,pathological type,and the degree of differentiation (P ＞ 0.05).A positive correlation was existed between the EGFR and TNM stages (x2 =5.43,P ＜0.05).The AKT was positively related to the size,T stage,and TNM stage of the tumor,respectively (x2 =4.73,4.95,5.32,P ＜0.05 orP ＜0.01).The levels of AKT (x2=4.83,4.75,P ＜0.05) and EGFR(x2 =4.67,4.58,P ＜0.05) in the gastric cancer tissues with lymph node and/or distant metastasis were significantly higher than the gastric cancer tissues without metastasis,respectively.Conclusions The over-expressions of AKT and EGFR would benefit the diagnosis and stages of a gastric cancer and the determination of its metastasis.

Objective To explore continuous renal replacement therapy(CRRT) machine for plasma exchange in critical disease in children.Methods Retrospective study of 8 patients(8 month to 14 years,mean 5.7 years) and 32 plasma exchange treatments,after(adowble) lumen catheter inserted into the subclayian venous,using the Baxter BM25 machine with commercially available plasma filters.Results Five patients(3 ABO-incompatibility in bone marrow transplantation,1 thrombotic thrombocytopaenic purpura TTP,1 sepsis) gained full recovery.One systemic lupus erythematosus(SLE) and 1 sepsis experienced moderate improvement while 1 case of acute disseminated encephalomyelitis failed PE treatment.The average total exchange volume was 80-100 mL/kg,achieved at a blood flow rate of 5-10 mL/(kg?min) and a turnover rate of 60-120 mL/(kg?h) over a 3-hours duration.Thirty-one PE treatments were finished smoothly,one of which experienced the serious complication involving plasma filter.Conclusion Plasma exchange therapy is a safe and effective procedure for severe autoimmune abnormalities and pathogen removal in children.

Objective To determine the iodine content of common foods in different geographical areas (coastal city,coastal rural area,mountainous city and rural area) in Fujian Province and provide basic data for evaluation of dietary iodine intake.Methods In 2010,based on the types of food of the total diet study,one food sample(consumption rate is greater than 1％) was collected in coastal city(Taijiang),coastal rural area(Xiang'an),mountainous city (Sanyuan) and rural area(Mingxi).These foods including cereal,beans,potato,meat,eggs,milk,aquatic products,vegetables,fruits,sugar,beverages,liquor and seasoning,and so on 184 kinds of common foods.The iodine content of these food was tested by As (Ⅲ)-Ce4+ catalytic spectrophotometry.Results Among the 184 kinds of food tested,164 were not indicated food iodine content in the Chinese Food Composition Tables (2004).The iodine content of common food in Fujian Province in descending order were salt (30 000 μg/kg),aquatic products(341.4 μg/kg),eggs(255.9 μg/kg),dairy(106.7 μg/kg),meat(103.2 μg/kg),cereals (40.7 μg/kg),vegetables(30.7 μg/kg),beans(12.9 μg/kg),sugar(8.5 μg/kg),fruits(6.7 μg/kg),potatoes(2.4 μg/kg) and alcohol(2.1 μg/kg).The iodine content of kelp and laver was the highest in all the food,which was 314 780.1,176 956.5 μg/kg,respectively.The iodine content of food from animal(241.4 μg/kg) was much higher than that of the food from plant(25.4 μg/kg).The iodine content of common cereals,potatoes,beans,sea algae,meat,eggs and aquatic products was compared in the four areas,and the difference was not statistically significant (M =135.5,20.0,42.0,16.0,54.0,4.0,x2 =1.4,all P ＞ 0.05).The iodine content of vegetables and fruits was compared,and the difference was statistically significant (x2 =8.5,M =204.5,all P ＜ 0.05).Conclusion The iodine content of different foods is different.

A comparative study on the glycolic acid oxidase (GO) of the domestic Spirulina(Arthrospira) platensis (S_(1)) from alkaline lake in Erdos Plateau and the imported S. (A.) platensis (S_(2)) and S. (A.) maxima (S_(3)) as well is made with colorimetric method. The results show that activity of GO (25℃, pH 8.0) of S_(1), S_(2 )and S_(3) is 70.9 U/gFW, 59.6 U/gFW and 80.9 U/gFW respectively; the GO's optimum temperature of S_(1)、S_(2) and S_(3 )is 30℃; the GO's optimum pH value of S_(1 )is 8.6,while that of S_(2 ) 8.2 and that of S_(3) 8.4; the GO of S_(1 )is stable from 0℃ to 35℃ and from pH 7.6 to pH 10.0, while that of S_(2) from 0℃ to 30℃ and from pH 8.0 to pH 9.0 and that of S_(3) from 0℃ to 35℃ and from pH 8.0 to pH 8.6. Adaptive range of S_(1) GO for temperature and pH is wider, and activity at low and high temperature and under strong acidand alkali conditions is higher than that of the imported species.

Objective To investigate the effect of combination of ganglioside and hyperbaric oxygen on spastic cerebral palsy. Methods 128 infants with spastic cerebral palsy were divided into treatment group (n=70) and control group (n=58), who received ganglioside and hyperbaric oxygen or cytidine diphosphate choline. The infants in the treatment group were divided into young group (6～12 months, n=38) and old group (1～3 years, n=32) according to their age. They were assessed with Ashworth scale and Functional Independence Measure (FIM) before and 3 courses after treatment. Results The scores of Ashworth scale and FIM improved more in the treatment group than in the control group (P<0.01) after treatment, as well as in the young group than in the old group (P<0.01). Conclusion The combination of ganglioside and hyperbaric oxygen is effective on spasticity and activities of daily living in infants with spastic cerebral palsy. The younger the infants are, the more effective it is.

Objective To set up a system in vitro to rapidly recover plasma proteins lost during artificial-liver treatment.Methods The polyprotein precipitation was obtained by all proteins whose isoelectric point pH value were between 7.3 and 5.1,which collided with each other and aggregated using gradient pH co-precipitation(adding 1 mol/L citric acid slowly in the plasma solution to change the pH values gradually from 7.3 to 5.1 in 5 h)combined with salting out(degree of saturation of NaCl is 33%,reacted for 5.5 h at 4℃)or low-temperature ethanol precipitation(40% ethanol, reacted for 5.5 h at -7℃)so that to get rid of toxicants by discarding the supernatant.Results In the range of pH 5.1-7.3,50%(29g/57g)of the total plasma proteins had been recovered by the gradient pH salting out and 41%(25 g/61g)by the gradient pH low-temperature ethanol co-precipi- tation.The protein remained in the supernatant was mostly albumin and its combined bilirubin.The levels of total bilirubin decreased to 0.07% and 0.06% of the original levels by these two methods respectively and the serum HBV DNA level decreased to be undetected(quantitative PCR).Conclu- sions The proteins with close isoelectric point can co-precipitated with the presence of high concen- tration of NaCl or low-temperature ethanol and by changing the pH value gradually.The total protein in the discarded plasma during artificial-liver treatment can be recovered rapidly using the gradient pH coprecipitation.
