Objective To evaluate the efficacy of surgical repair for non-circumferential defect of bile duct in Mirizzi syndrome.Methods The clinical data of 42 patients with Mirizzi syndrome with non-circumferential defect of bile duct who were repaired using own tissues such as gallbladder pedicle flap,umbilical venous flap and omental flap were analyzed.The defect in the bile duct were repaired using gallbladder pedicle flap in 30 patients,umbilical venous flap in 8 patients and omental flap in 4 patients.Results All patients were operated successfully.There was no operative mortality.There were 2 patients who developed postoperative complications.There was one postoperative bile leakage in a patient who was repaired using an umbilical venous flap.The other complication was residual bile duct stones.The patient with postoperative bile leakage was drained through a drainage tube which was removed after 7 d.The residual bile duct stones were removed by endoscopy through a T-tube sinus after 9 months.All patients were confirmed by T-tube cholangiography after 9-12 months to have no stones,bile duct stenosis or any other abnormalities.The T-tube was then removed.All patients were followed up for 1-5 years,and had no cholangitis,abdominal pain,jaundice or fever.Conclusions Using own tissues such as gallbladder pedicle flap,umbilical venous flap and omental flap to surgical repair the defect in the bile duct of patients with Mirizzi syndrome is effective.This surgical treatment is a good choice.

Objective:To explore the effects of radiation on hippocampus neuron and the related damage mechanism in order to provide the theory base for treatment strategy of radiation brain injury. Methods:We looked up the scientific literature including following methods. Pregnant mice were irradiated with tritiated water, and then the contents of SOM in pars intermedia and AVP in hypothalamus of newborn mice were detected by radioimmunoassay. Pregnant rats were irradiated with tritiated water or X-ray, and the neuronal cells derived from the newborn rats were cultured. The morphology of cultured neuronal cells was compared with those of normal neuronal cells. The number of apoptotic cells in cortical fifth layer was measured by HE staining. Results:After radiation with tritiated water, the level of SOM in pars intermedia of newborn mouse and AVP content in hypothalamus content of male newborn mouse significantly increased and decreased, respectively. Radiation with tritiated water could result in the morphology change of neuronal cells and increase the percent of apoptosis cells in cortical fifth layer. Moreover, the percent of apoptosis cells in tritiated water group was higher than that in the X ray group. Conclusion: Radiation could impact on brain neuropeptide contents, and neurobehavioral, learning and memonic ability, result in the morphology change of hippocampal neurons, and induce the midbrain cells apoptosis.

Objective To explore the experience of surgical treatment for appendiceal carcinoid.MethodsThe clinical data of 12 appendiceal carcinoid cases received surgery were retrospectively studied.ResultsPreoperatively,all the 12 cases were considered as appendicitis.The definite diagnosis was verified by pathologic study postoperatively.Among the 12 cases, tumors less than 1 cm 9 cases, between 1 cm to 2cm 2cases, but without serosal involvment or lymph node metastasis(2 cases) recieved simple appendectomy.One case with a tumor larger than 2cm and serosal involvment underwent fight hemicolectomy.ConclusionOwing to its lack of specific symptoms,the diagnosis of appendiceal carcinoid was usually reached after operation.The choice of surgical procedures should based on the size and depth of invasion of the tumor and lymph node metastasis status.

Colorectal neuroendocrine neoplasm (NEN) is originated from colorectal neuroendocrine cells.The incidence of colorectal NEN is low,however it has been increasing in recent years.As the research work has gone further,WHO has graded colorectal NEN to neuroendocrine tumor,neuroendocrine carcinoma,mixed gland-neuroendocrine carcinoma and hyperplastic and pre-neoplastic lesions.Although colorectal NEN cells can produce hormones and have endocrine functions,the clinical symptoms may not be shown.The diagnosis and treatment for colorectal NEN are different according to different classifications and stages.

Objective To investigate the changes of the hemostatie coagulation markers in pregnancy induced hypertension (PIH)and significance.Methods The blood samples were collected from 70 normal pregnant women (control group) and 66 pregnant women with PIH (PIH group).Platelet count (PC), mean platelet volume ( MPV ), prothrombin lime (PT), partial thromboplastin time (AFIT), fibrinogen (FIB),D-dimmer (D-D)were measured.Results Compared with the control group,the level of PC,PT, APTT in the PIH group were significantly decreased [(178.32±51.08) × 10~9/L vs (186.17±40.02) × 10~9/L, (10.54±0.34) s vs(11.07±0.49) s, (26.23±3.12) s vs(28.08±4.31) s](P<0.05 or <0.01), while those of FIB,MPV,D-D were significantly increased [(5.34±0.68) g/L vs (4.02±0.73) g/L, (11.10 ± 2.31 ) fl vs (8.95 ± 1.37) fl, (0.46 ± 0.27) mg/L vs (0.18 ± 0.19) mg/L](P < 0.01 ).The levels of FIB and D-D were significantly increased in severe preeclampsia (34 cases) than those in mild preeclampsia (32 cases) (P < 0.01 ).The level of PT was lower and FIB, D-D were increased in early onset preeclampsia ( 31 cases ) than those in late onset preeclampsia (35 cases) (P < 0.05 or < 0.01 ).Conclusions There is hypercoagulative state in pregnant women with PIH.The disorders of coagulation function may be more severe in early onset preeelampsia than those in late onset preeclampsia.

Surface plasmon resonance (SPR) sensing technology is a high-tech optical detection technolo-gy developed quickly in recent years, which combines biology, polymer chemistry and sensing technologies to form a rapid, sensitive, specific, portable and easy to operate detection technology. This paper outlines the mech-anism of SPR sensing technology for detection of low molecular weight analytes, the main application methods and research progress, discusses the advantages and shortages of the method, and foretastes the development prospect of this technology.

Spleen tyrosine kinase(Syk) has been considered to be a signaling molecule of hematopoietic cells,which play an important role in lymphocyte maturation and activation of immune cells.Recent studies showed that Syk plays a crucial role in regulation of proliferation and migration in vascular smooth muscle cells.Prominent pathways include mitogen-activated protein kinases,phosphatidylinositol 3-kinases,Src and Rho-activated protein kinase.In this review,the role of Syk in those signal pathways is summarized.
