Objective To investigate and analyze the severe complications and their surgical managements after endoscopic sphincterotomy(EST).Method 36 patients with complications after EST such as severe hemorrhage, perforation and severe pancreatitis were analyzed,of them there were 16 cases of hemorrhage, 11 case of perforation, 6 cases of hemorrhage combined with perforation and 3 cases of severe pancreatitis combined with perforation. Results 14 cases of merely hemorrhage patients, 11 cases of merely perforation patients, 1 case of perforation combined with severe pancreatitis patient and 3 case of perforation combined with hemorrhage patient were survived while 2 case of merely hemorrhage patient, 3 cases of perforation combined with hemorrhage patients and 2 case of perforation combined with severe pancreatitis patients died.Conclusions Hemorrhage is the most common complication of EST and most complications can be healed well through expectant treatment. Once severe complications occurred, prompt operations are the keys to lower the mortality.

Objective To study a novel method of laparoscopic treatment for indirect inguinal hernia in children. Methods Forty-eight children with indirect inguinal hernia (right: 31 cases, left: 13 cases, bilateral: 4 cases) were treated by one port laparoscopic surgery. Among those with unilateral hernia, contralateral latent hernia was found in 5 children. All the patients underwent high ligation of internal annulus under laparoscope. Results The duration of operation was 7~14 min (mean, 9 min). The mean postoperative hospital stay was 24 h. Skin sutures were not required. Follow-up for 3~15 months (mean, 9 5 months) revealed no recurrence. Conclusions One port laparoscopic high ligation of internal annulus is effective, minimally invasive and simple.

Objective: The influence on the blood glucose,ALB,LYM,K+,Na+,Cl-,TG,TC and so on after the use of different nutrition formula was observed in patients with cerebrovascular disease and type 2 diabetes.Methods: 40 patients who suffered from cerebrovascular diseases and type 2 diabetes were divided into two groups: one group using the ordinary formula and the others using special-purpose formula of diabetes.The levels of blood glucose,ALB,LYM,K+,Na+,Cl-,TG,TC were monitored.Results: The patient's blood glucose after use of ordinary formula rised obviously and insulin or the oral drug for decreasing blood glucose was used.The blood glucose in special-purpose diabetes formula group didn' t increase obviously,and there was not the need of using insulin(P

Objective To evaluate the modification of C_(60) on the radiation effects of ~(60)Co-γ irradiation on zebrafish.Methods The adult and embryonic zebrafish were used as model organisms to examine the potential of C_(60) to elicit oxidative stress responses on the surviving rate,hatching rate and malformation occurrence,both upon exposure to light or in the dark.Reactive oxygen species (ROS) production and DNA damage were examined as the possible underlying mechanism.Results 500 × 10~(-9) nano-C_(60) waterborne exposure could enhance the γ-irradiation effects by decreasing adult fish survival upon light exposure,which resulted in ROS and DNA damage increasing.The hatching rates were also inhibited with higher malformation,though dark exposure did not make any enhancement,except that the 5000× 10~(-9) C_(60) would inhibit larvae hatching and induced more malformation.Conclusions Waterborne nano-C_(60) exposure may enhance the radiation effects on zebrafish,ROS production and DNA damage increasing may be the underlying mechanism.

BACKGROUND: Pathogenesis and pathophysiological changes of chronic compressive cervical myelopathy havenotbeen completely clarified.OBJECTIVE: To establish an animal model of experimental chronic compressive cervical myelopathy for the exploration of the pathological and electrophysiological changes after chronic spinal compression.DESIGN: A randomized and controlled observatory study using experimental animals as subjects.SETTING: An Animal Experimental Center of a University and an Orthopaedic Laboratory of Affiliated Hospital of a Military Medical University MATERIALS: The study was conducted in the Animal Experimental Center of Nantong Medical University and the Orthopaedic Laboratory of Shanghai Changzheng Hospital from June 2002 to April 2003. Sixty 12-week healthy Chinese rabbits of either gender with a bodymass between 2.5 kg and 3.0 kg were randomly divided into control group( n = 6) and study group( n = 54).METHODS: Titanic metal screw was put into C5 vertebra through cervical anterior approach for progressive compression to establish chronic cervical myelopathy model.MAIN OUTCOME MEASURES:Principal consequences: ①histological examination ;②electrophysiological examination. Secondary consequence:neural function evaluation.RESULTS: Totally 48 rabbits entered into result analysis, in which 6 rabbits from control group and 42 rabbits from study group. Modified Tarlov's motor function evaluation was 3 in 31 rabbits with compression signs, and 4 in 11rabbits without compression signs. The latency of N1 wave in cortical somatosensory evoked potentials (CSEP) was (9.11 ± 1.61 ), ( 11.36 ± 2.17)and (17.55 ± 3.73) ms respectively in animals of control group, animals of study group without compression signs and animals of study group with compression signs. The lantency of CSEP N1 wave was significantly longer in animals of study group with compression signs than that of the animals in the control group and study group without compression signs (P<0.05).CONCLUSION: This animal model can simulate clinical invasion process of chronic compressive cervical myelopathy. The severer the spinal compression is, the more often the compression signs appear, the longer the lantency of CSEP N1 wave is, and the more serious the spinal pathological damages are.

Objective To investigate the role of Stathmin in pancreatic cancer invasion and metastasis and its relationship with DNA methylation. Methods Immunohistochemical detection of MBDI and Stathmin protein expression in 40 cases of pancreatic cancer and 15 cases ot normal pancreatic tissue were performed,followed by analysis of their clinical and pathological relationship with pancreatic cancer; Human pancreatic cancer cell line BxPC-3 was treated with 5-Aza-2-dC (AZA).Both qRT-PCR and Western blot analysis of Stathmin expression were used before and after AZA treatment; Stathmin-siRNA transfected BxPC-3 cells were divided into the Stathmi-siRNA group and the empty vector control group.Transwell chamber invasion assay and animal experiment were performed to measure the changes in cell invasion and metastatic capability. Results lmmunohistochemistry showed positive MBDI and Stathmin expressions in 28 (70%) and 24 (60%) out of 40 cases of pancreatic cancer,respectively,which were significantly higher than that in the normal pancreatic tissue (P< 0.05); MBDI and Stathmin protein expressions were positively correlated (r =0.356,P =0.037),so were MBDI expression and lymph node metastasis (P=0.023).Stathmin expression was significantly correlated with clinical staging and lymph node metastasis (P =0.002,and P =0.001,respectively).After AZA treatment,both Stathmin mRNA and protein expression in BxPC-3 were significantly decreased.Transwell chamber invasion assay showed that compared with the control group,the cell invasion capability of the Stathmin-siRNA group was significantly decreased (P<0.05).Animal experiment showed that the incidence of liver metastasis was significantly lower in the Stathmin-siRNA transfected group than the empty vector control group (P<0.05).Conclusion Demethylation may contribute to the reduction of Stathmin expression in pancreatic cancer and further improve the prognosis of pancreatic cancer patients.
