Objective To explore the pattern of lymph node metastasis in patitsen with squamous cell carcinoma of the thoracic esophagus and its significance in lymphadenectomy.Methods The clinical data of 230 patients who received radical esophagectomy with three-field lymphadenectomy was analyzed.The metastatic sites of lymph nodes were correlated with tumor location by chi-square test.Logistic regression was used to analyze the relationship between clinic pathoingical factors and lymph node metastasis.Results Lymph node metastases were found in 133 of the 230 patients(57.8%).The average number of resected lymph nodes was 25.3? 11.4 per patient(range 11～71).The rates of lymph node metastasis were 41.6%,19.44%and 8.3%in the neck,thoracic medi- astinum and abdominal cavity for patients with upper thoracic esophageal carcinoma,33.3%,34.7%and 14%for patients with mid- die thoracic esophageal carcinoma and 36.4 %,34.1%and 43.2 %for patients with lower thoracic esophageal carcinoma.No signifi- cant difference in cervical or thoracic metastatic rate was observed among upper,middle and lower thoracic carcinoma.The difference in lymph node metastatic rate for nodes in the abdominal cavity was significant among upper,middle and lower thoracic carcinoma. The lower thoracic esophageal cancers were more likely to metastasize to the abdominal cavity.Logistic-regression showed depth of tu- mor invasion and angiolymphatic invasion were factors influencing lymph node metastasis.Conclusion Cervical and mediastinal node dissection should be performed independently from tumor location.Abdominal node dissection should be conducted more vigorously for lower thoracic esophageal cancer than of other locations.Patients with greater tumor grade,depth of tumor invasion and angiolymphatic invasion were more prone to develop lymph node metastasis.

Objective:To establish a random amplified polymorphism DNA(RAPD) method for classification of origin fungi of the Chinese traditional medicine Red Kojic. Methods:The genome DNA of 7 ordinary species Monascus including M. purpureus and a strain of Aspergillus terreus were extracted by CTAB. The content of DNA was assayed doubly by fluorescence intensity of ethidium bromide (EB) and spectrometer. Amplification products were detected by agarose gel electrophoresis and clustering analysis by PHYLIP 3.5c. Results:A characteristic pattern was produced depend on one of the 10 primers screened from 60 random primers, and the genome was amplified. The diversities of the fingerprint patterns of Monascus was obvious, by which Monascus can be distinguished easily. The results were consistent with that of morphologic study. Conclusion:RAPD is a new assay technique. It can be used to classify and identify of Monascus fungi. [

Objective To investigate the clinical value of prenatal ultrasonography in diagnosing fetal aortic atresia.Methods Ultrasound images of 9 cases with fetal aortic atresia confirmed by autopsy were retrospectively analysed and summarized.Results Fetal echocardiography showed ascending aorta and aortic arch were thin in seven cases and unclear in two cases.Color Doppler flow imaging showed fetal aorta no blood connection with left ventricle and reverse blood flow in aortic arch among all 9 cases.There were 6 cases associated with hypoplastic left heart syndrome,two cases associated with ventricular septal defect and well-developed left ventricle,one case complicated with complete atrioventricular septal defect.Nine cases were detected at average gestational age (26.0 ± 2.6) weeks,minimum gestational age was only 16 weeks pregnant.Conclusions Prenatal ultrasound diagnosis of fetal aortic atresia has important clinical value.Ascending aorta and aortic arch are thin or unclear,no blood flow connection between fetal aorta and left ventricle and reverse blood flow in aortic arch are major diagnostic evidences.Color Doppler flow imaging is helpful for early diagnosis.

Objective To modify the methods of operation and establishment of cerebral ischemia rat models made by thread occlusion. Method We randomly divided 120 male SD rats into a common group (n = 50), an improvement group (n = 60) and a sham-operated group (n - 10). Rats in the common and improvement groups were made into models using the common and improvement methods separately. All models were evaluated on the basis of physical sign indices and 2,3,5-triphenyltetrazolium chloride (TTC) staining. The TTC staining results were taken as gold standards. Then, we compared the achievement ratios of the two groups, and computed the sensitivity and specificity of every physical sign index based on these standards. The χ~2 or correction χ~2 test was used to compare the ratios. Results (1) The achievement ratio in the improvement group was significantly higher than that in the common group (71.67% vs. 52.00%, P = 0.034). (2) The sensitivity of evaluation for both common and improvement methods was 98.55%. However, the specificity of evaluation for the improvement method was significantly higher than that for the common method (100.00% vs. 40.00%, P =0.000). Conclusions The establishment achievement ratio and evaluation correctness of models are obviously elevated by modification of the operation and establishment methods.

Objective To review the clinical characteristics and treatment of type 1 diabetes mellitus (T1DM) in children. Methods The clinical data of 103 children with T1DM admitted to our hospital from Februry 2002 to August 2010 were retrospectively analyzed. Thirty one cases with diabetic ketoacidosis (KDA) were treated with continuous insulin pump (group A) or basal-bolus insulin therapy (group B). The differences in blood glucose control time, the rate of hypoglycemic episodes, glucose fluctuation, fasting blood glucose (FBG), 2 h postprandial blood glucose (2 hPBG), insulin dosage, the time of urine acetone bodies disappear and length of stay were compared in two groups. Results The age of 103 children with T1DM was from 38 d to 15. 33 y with an average of (8 ±3) y; most of them was 7 - 10 y (47, 45.6% ). Seventy eight children were first diagnosed accounting for 75.7%; boys accounted for 55.3% of total. Fifty one cases (49.5%) were diagnosed in winter and spring and 67 (65.2%) had infections, most of them were respiratory tract and gastrointestinal infections. Sixty two cases (60. 2% )presented as diabetic ketoacidosis at the first onset, including 4 cases (3.9%) with cerebral edema. Some patients were complicated by Hashimoto's thyroiditis, hyperthyroidism, SLE and other autoimmune diseases.Among 31 cases with ketoacidosis the FBG and PBG were decreased significantly after treatment, there were no significant differences between two groups (P ＞ 0. 05 ). Compared to group B the correction time of DKA and urine acetone bodies was shorter, and reached the targeted glucose levels more quickly, the frequency of blood fluctuation and the hypoglycemia was significantly lower, the length of stay was shorter, and the daily dose of insulin was lower in group A; the differences between two groups were statistically significant ( P ＜0. 05 or P ＜0. 01 ). Conclusions The clinical symptoms at first onset of T1 DM in children are not typical,and likely to be combined with DKA; infection may be one of the inducing factors for DKA. Continuous subcutaneous insulin infusion with pump can control the blood glucose more effectively and equably, and are convenient for use by children; so it is a better treatment option for type 1 diabetes mellitus in children.
