Objective To study preoperatively on TNM staging of esophageal carcinoma by endo-scopes ultrasonography ( EUS). Methods Sixty-one patients with esophageal carcinoma were preoperatively staged by EUS. The results were compared with the postoperative histopathological staging according to the new (1997) TNM classification. Results Clinical staging of T subsets by EUS was reliable with an overall accuracy rate of 86. 9% , while that of N subsets was relatively more difficult with an overall accuracy rate of 52. 5% ; sensitivity and specificity of regional lymph nodal metastases were 88. 9% and 23. 5% respectively. Conclusion EUS is relatively an accurate measure in assessing the depth of tumor infiltration, whereas further efforts are needed to improve the accuracy in N staging. EUS will be helpful in choice of the appropriate therapeutic procedure and predicting the possibility of surgical resection.

Objective To observe the long-term effects of maternal mild hyperglycemia on the growing development and glucose and lipid metabolism in intergenerational rat offspring.Methods Streptozotocin (25 mg/kg) was administered to 14 pregnant Wistar rats intraperitoneally on the first day of gestation to induce an animal model of mild intrauterine hyperglycemia,which was successful in nine rats.Seven pregnant rats without streptozotocin intervention served as controls.Female first-generation offspring (F1) rats were intercrossed with normal male rats to obtain the second-generation offspring (F2) rats.F1 and F2 rats were divided into 8 groups:female group (group F1-G-♀) or male group (group F1-G-♂) exposed to intrauterine hyperglycemia;female group (group F1-C-♀) or male group (group F1-C-♂) exposed to intrauterine euglycemia;transgenerational female group (group F2-G-♀) or male group (group F2-G ♂)exposed to intrauterine hyperglycemia;and transgenerational female group (group F2-C-♀) or male group (group F2-C-♂) exposed to intrauterine euglycemia.Body weight of the offspring was recorded.At the age of 28 weeks,the weight of pancreas and visceral fat,fasting plasma glucose (FPG),fasting insulin,total triglyceride,total cholesterol,high-density lipoprotein-cholesterol,low-density lipoprotein-cholesterol were measured in all groups.Two sample t test was used for statistical analysis.Results (1) At 4,24 and 28 weeks old,the body weight of group F2-G-♀ [(177.3± 12.3),(314.5± 13.9) and (322.3± 16.2) g] was remarkably increased compared with group F2-C-♀ [(164.3±6.0),(290.2± 18.3) and (300.2± 16.2) g,t=-2.324,-2.584and-2.359,all P ＜ 0.05].(2) At 28 weeks,the pancreas weight and the ratio of pancreas weight to body weight of group F1-G-♀ [(0.53 ±0.05) g and (0.17±0.02)％] were decreased significantly compared with group F1-C-♀ [(0.65±0.04) g and (0.21±0.02)％,t=4.159 and 2.483,both P ＜ 0.05].The pancreas weight,ratio of pancreas weight to body weight,visceral fat weight and fat weight of mass ratio in groups F2-G-♂ and F2-G-♀ were not remarkably different from groups F2-C-♂ and F2-C-♀,respectively (all P ＞ 0.05).(3)The level of FPG at three weeks of age in F2-G-♀ group was higher than in F2-C-♀ group [(6.5±0.8) vs (4.9±1.2) mmol/L,t=-2.786,P ＜ 0.05],and it was also higher in F2-G-♂ group than in F2-C-♂ group [(6.3±0.8) vs (4.7± 1.0) mmol/L,t=-2.696,P ＜ 0.05].At 28 weeks,the FPG level was (6.7±0.6) and (8.4±2.2) mmol/L in F2-G-♀ and F2-G-♂ groups,being higher than in F2-C-♀ and F2-C-♂ groups,respectively [(5.8±0.5) and (6.2± 1.0) mmol/L,t=-2.695 and-2.337,both P ＜ 0.05].Compared with F1-C-♀ group [(0.61 ±0.10) mmol/L],the high-density lipoprotein-cholesterol level was lower in F1-G-♀ group [(0.47±0.05) mmol/L,t=2.433,P ＜ 0.05].(4) In groups F1-G-♀,F2-G-♀ and F2-G-♂,the structure of the islet cells was obviously atrophic and disordered,and β-cells were slightly decreased and distributed unevenly,but group F1-G-♂ had significantly increased β-cells with hypertrophic islet size compared with control group.Conclusions F 1 rat offsprings exposed to mild intrauterine hyperglycemia experience excessive weight gain after birth,impaired structure of the islet,metabolic abnormality,increased visceral fat weight and glucose and lipid metabolism disorder,which show intergenerational inheritance and gender differences.

OBJECTIVE: To analyze the characteristics of medical malpractice from different grades of hospitals and to explore forensic investigation strategies in assessing medical dispute. METHODS: A total of 206 cases of medical dispute from 2009 to 2010 investigated by the Department of Forensic Medicine in Nanjing Medical University were selected and analyzed according to fault incidence, fault-prone part, and degree of causality in the treatment. RESULTS: Among the 206 cases analyzed, tertiary hospitals, secondary hospitals and primary hospitals showed medium, high and low error rate, respectively. A majority of medical malpractice cases were distributed in the departments of surgery, medicine and gynecology. CONCLUSION The frequency and severity of medical malpractice in primary hospitals were high, which were gradually reduced in tertiary and secondary hospitals.

BACKGROUND: Jaw defects are common clinically. It is desirable to find ideal seed cells combined with scaffolds to construct tissue engineered jaws for curing these diseases. OBJECTIVE: To investigate the growth characteristics of bone marrow mesenchymal stem cells (BMSCs) transfected with basic fibroblast growth factor (bFGF) gene after seeded on coral scaffold in vitro. DESIGN, TIME AND SETTING: An experimental study of bone tissue engineering was performed in the Research Institute of Stomatology, Sun Yat-sen University between March 2006 and June 2008. MATERIALS: Natural coral from China Hainan bench was made into pieces of 8 mm×8 mm×2 mm. METHODS: BMSCs were isolated from New England rabbits by density gradient centrifugation and then purified by adherent separation. bFGF-pcDNA3 gene was transfected into BMSCs using Lipofectamine TM 2000. bFGF gene-transfected (transfected group) or untransfected (untransfected group)BMSCs were seeded on different coral scaffolds. In addition, bFGF gene-transfected BMSCs were simply cultured but not on the coral scaffold for control (simple culture group). MAIN OUTCOME MEASURES: BMSC proliferation was detected by methyl thiazolyl tetrazolium (MTT) assay and BMSC growth on coral scaffold was observed under the scanning electron microscope. RESULTS: MTT assay showed that the BMSC proliferation rate was significantly higher in the transfected group than in the untransfected group (P < 0.05) and that there was no significant difference in BMSC proliferation between the transfected and simple culture groups (P > 0.05). Scanning electron microscope results displayed that BMSCs adhered to and spread over the coral scaffold, exhibiting various appearances, with some cells had grown into scaffold micropores or spanned micropore surface, and some extracellular matrix secreted by BMSCs were found. CONCLUSION: The transfected group exhibited better growth of BMSCs transfected by bFGF gene than the untransfected group. These findings indicate that coral skeleton does not influence BMSC proliferation and can be used as a scaffold of BMSCs to construct tissue-engineered bone.
