Objective To evaluate the safety of a surgical appwach for transabdominal cardial carci- noma.Methods We retrospectively analyzed 326 patients undergoing transabdominal esophagastrostomy or esophagojejunostomy from 1998 to 2006 via the EEA(end-to-end anastomosis)stapler.Results By the surgi- cal approach for transabdominal cardial carcinoma,the average length of reseete esophagus above the carci- noma was about 6～8 cm realized the low average of remnant carcinoma at the margin and operation mortality and anastomotic leakage,which was lower than those in the thoraeotomy appmaeh significantly.Conclusion The transabdominal approach makes a clear operative field in posterio-inferior mediastinum,it is beneficial for radical resection of eardial carcinoma and intramediastinal esophagogastric or esophagojejunal mechanical anastomosis,and it fits to the old,the weakening and with the disease of heart and lung.

Objective To find out the consumption situation of iodized salt in Baotou, identify problems and take appropriate intervention measures, and to provide scientific basis for further consolidating the results of control measures, strengthening and improving the sustainable elimination of iodine deficiency disorders. Methods Three batches of each quarter, 54 salt samples were sampled in Donghe wholesale division and Qingkun wholesale division in Baotou city salt company during 2008 - 2010; each place of Damaoqi, Baiyun district, and Qingshan district were divided into five sampling areas according to the direction of east, west, south, north, and central position, one school was selected in each district, 30 students aged 8 to 10 from each school were selected, and home salt samples were taken, and salt iodine was tested by direct titration(GB/T 13025.7-1999). Results Qualified rate of wholesale iodized salt was 100%(378/378) during 2008 - 2010, and mean salt iodine was 30.4 mg/kg;qualified rate of household iodized salt was 99.8%(2417/2421 ), and mean salt iodine was 30.4 mg/kg; iodized salt coverage rate was 99.6% (2421/2430) and consumption rate of qualified iodized salt was 99.4% (2417/2430).Conclusions Qualified rate of iodized salt, coverage rate of qualified iodized salt and consumption rate of qualified iodized salt are 90% or more, which has reached the standard of sustainable elimination of iodine deficiency disorders.

Objective To study the changes and clinical significance of serum kalium,natrium,chlorine,calcium and glucose in children with febrile convulsion(FC).Methods Serum kalium,natrium,chlorine,calcium and glucose concentrations were measured in 41 children with FC(FC group),30 children with fever and without convulsion(fever group) and 30 normal children(normal group) by automatic biochemical detector.Results Serum kalium and calcium concentrations had no significant difference between FC group and fever group,but they were significantly lower than those of normal group(F=5.965,3.048 P0.05).Conclusions There are hyponatremia,hyperglycemia and lowered blood kalium and calcium in patients with FC.Hence,while treating the patient with FC,the disturbance of blood electrolytes and glucose need be corrected to avoid the recurrence of FC and the progressive injury of important organs such as brain.

Objective To investigate role of interleukin-1?(IL-1?),interleukin-8(IL-8),tumor necrosis factor-?((TNF-?)) and insulinlike growth factor-1(IGF-1) in meconium aspiration syndrome(MAS) in newborns.Methods The concentrations of(IL-1?),IL-8,TNF-? and IGF-1 in peripheral serum were detected in 32 newborns with MAS and 15 normal newborns by radio-immunity at the first,the third and seventh day after being born.Correlations between IGF-1 and changes of IL-1?,IL-8,TNF-? was analyzed.Results Compared with control group,the concentration of IL-1?,IL-8 and TNF-? increased significantly in newborns with MAS in three days after being born(all P0.05).On the other hand, the concentration of IGF-1 in newborns with MAS was obviously lower than that of normal newborns one week after birth.The concentration of IGF-1 showed negative correlations with that of IL-1?,IL-8 and TNF-?(r=-0.67,-0.61,-0.73 all P

Objective To explore the apoptosis of alveolar epithelial cell(AEC)and the dynamic changes of Caspase-3 mRNA and Bax and Bcl-2 expression in premature rat with hyperoxia-induced chronic lung disease(CLD).Methods Sixty premature rats within 1 day after birth were randomly divided into 2 groups:hyperoxia group(n=30)and control group(n=30).Hyperoxia-induced premature rat CLD models were prepared,and situ nick end-labeling(TUNEL),reverse transcription polymerasechain reaction(RT-PCR)and immunohistochemical technique were used to determine apoptosis index(AI)of AEC and the expressions of Caspase-3 mRNA and Bax and Bcl-2 proteins in lung tissues at 1,3,7,14 and 21 d after birth.Results Compared with control group,in the hyperoxia group,on the third day after exposured to hyperoxia,the AI of AEC and the expressions of Caspase-3 mRNA and Bax began to increase,and the expression of Caspase-3 mRNA was kept at high level on 7-21 d.The expression of Bcl-2 began to decrease on 7 d,and significantly decreased on 7-21 d.AI of AEC was positively correlated with the expression of Caspase-3 mRNA and Bax,and negatively with the expression of Bcl-2.Conclusions Hyperoxia may induce the increased expression of Caspase-3 mRNA,which might result in the abnormal expression of Bax and Bcl-2 in lung tissues and their imbalance,which might be one of the underlying mechanisms of apoptosis of AEC in premature rats with CLD.

Objective To study the clinical characteristics and curative effects of pancreatic cystade- nocarcinoma in order to improve its diagnostic and therapeutic accuracy.Methods A retrospective analysis was done on the clinical materials of 13 cases of pancreatic cystadenocarcinoma hospitalized in Shanxi Cancer Hospital from 1990 to 2006.Results The preoperative diagnosis were as follows:pancreatic cystadenocarci- noma 6 cases,pancreatic cystadenoma 2 cases,pancreatic cancer 1 case,pancreatic pseudocyst 4 cases.The misdiagnosis rate was 53.8 %.Surgical operation was done on the 13 cases,and 10 of them were treated by radical operation.A 5-year follow-up was done on 6 still alive cases,and 1 of them lived over 11 years.3 cases were treated by palliative operation,and all of them died within 3 years.Conclusion Since there is no specific clinical manifestations of pancreatic cystadenocarcinoma,it is very difficult to get an accurate preop- erative diagnosis.Radical operation is the most effective therapeutic methods.

OBJECTIVETo observe the effect of Shugan Liangxue Compound (SLC) for relieving hot flashes in breast cancer patients medicated with tamoxifen.

METHODSA randomized, double blind clinical trial for observing the therapeutic effects of SLC was carried out on 73 breast cancer patients hospitalized from October 2004 to November 2006, who were treated with tamoxifen, and revealed hot flashes. They were randomly assigned to two groups, the 37 in the treated group treated by SLC, and the 36 in the control group treated with placebo. Taking the improvement of hot flashes as an end point index and that of sleep as a secondary index, the effects of treatment were compared by Kupperman scoring with the average times of hot flashes per day and condition of sleep within 1 week before treatment as baseline.

RESULTSThe effects on 66 patients (33 in the treated group and 33 in the control group) were evaluable. In the treated group hot flashes disappeared in 5 patients (15.2%), relieved in 14 (42.4%) and unchanged in 14 (42.4%); while in the control group, it disappeared in none, relieved in 10 (30.3%) and unchanged in 23 (69.7%), comparison between groups showed significant difference (P = 0.012). As for the condition of sleep, it was improved in 21 (63.6%) and unchanged in 12 (36.4%) in the treated group; while the condition of sleep in the control group was improved in 13 (39.4%) and unchanged in 20 (60.6%), also with significant difference between the two groups (P = 0.002).

CONCLUSIONSLC is effective in alleviating tamoxifen-induced hot flashes and improving the condition of sleep.
