Objective To investigate the readiness for hospital discharge of patients who had undergone spinal operation at West China Hospital, Sichuan University, to guide the medical care and health education. Methods A total of 164 patients after spinal operation who have readying to discharge were selected and investigated by General Information Questionnaire, Activity of Daily Life Scale and Readiness for Hospital Discharge Scale. Apply the Excel for data inputting, SPSS19.0 for statistical analysis and choose rate, x±s and so on for statistical description according to the types of data. Results Of all the 164 patients, 47 cases (28.7%) weren′t well prepared, 117 cases (71.3%) were well prepared;the score of
Readiness for Hospital Discharge Scale was (142.38±34.23 points and the average score of all the articles was (7.12±1.72) points. Conclusions The readiness for hospital discharge score of patients who had undergone a spinal operation at West China Hospital, Sichuan University is low and their readiness for hospital discharge is inadequate. Medical staff can improve the patients′readiness for hospital discharge by strengthening health guidance in order to promote the recovery of patients.

Objective To discover the vital role of Rab27B in tumor cells and its potential molecular mechanism by means of quantitative proteomics analysis of Rab27B knockdown in MHCC97H.Methods The expression of Rab27B in MHCC97H cells was knocked down by the combination of Tet-on advanced inducible expression system and RNA interference technology.Then, proteins extracted from the cells were identified by LC-MS/MS system after FASP digestion and iTRAQ 4-plex labeling. Finally, the properties of differentially expressed proteins, including the subcellular localizations, biological processes and molecular functions, were analyzed by the bioinformatics method.Results There were 448 differentially expressed proteins (|Ratio|>1.21, P<0.05) identified in MHCC97H cells after Rab27B knock-down.The expression levels of 229 or 219 proteins were positively or negatively correlated with Rab27B, respectively. These differentially expressed proteins were mainly involved in vesicle transport, macromolecule localization, cellular response to stimulus.Furthermore, there were 26 differentially expressed proteins participating in 8 tumor-related signal pathways, eleven of which were in the focal adhesion signal pathway.Conclusion The analysis of quantitative proteomics in Rab27B-knockdown MHCC97H cell line by iTRAQ suggests that Rab27B not only has an impact on the exosomal secretion of tumor cells, but also regulates master proteins in signal pathways involved in cell proliferation and migration.

[Objective]To study the clinical application value of the measurement of thyroid function during early pregnancy.[Methods] Six hundred and thirteen women in early pregnancy(observation group)accepted thyroid function lest.Patients with abnormal thyroid function received therapeutic intervention.The results were compared with 586 pregnant women(control group)who didn't get thyroid function screening and treatment.[Results]There were 182 cases(29.69％)out of 613 pregnant women with various thyroid diseases.The incidences of fetal distress,premature rupture of membrane,gestational hypertension and neonatal deformity in observation group were significantly lower than those in control group[3.92％(24/613)vs.7.34％(43/596),5.06％(31/613)vs.12.97％(76/586),2.28％(14/613)vs.5.46％(32/586),1.63％(10/613)vs.5.63％(33/586),P＜0.01].[Conclusion] Thyroid function detection and therapeutic intervention during early pregnancy has important clinical value.

ObjectiveTo assess the effect of balloon o f ureter through ureteroscopy for management of ureter stenosis.Met hods42 cases ureter stenosis underwent balloon dilation of ureter,2 2 being male,20 being female.The average age was 46 years.There was 5 ureteropel vic junction stenosis,8 upper ureter stenosis,5 middle part stenosis,24 lower pa rt stenosis.The length of stenosis was from 0.5 cm to 2.0 cm.Result sThe balloon dilating catheter was passed over the ureter stenosis area and was put in proper position in 39 cases.3 cases were failed(7.2%). 37 ca ses successfully underwent balloon dilation of the ureter on one session.All pat ients were followed up for 6 to 24 months(mean 14 months).The degree of hydronep hrosis decreased with no recurrence in 37 cases(88.1%).2 casese failed to gain the effect after the double-J stent was removed(4.7%). There are no serious co mplication found in all patients.ConclusionsBalloon di lation of ureter offers many advantages,such as:good result,repeatable and reduc ing the cost and hospital stay.

Objective To study the pathological and ultramicrostructural characteristics of organ tissues in relation to the clinical course of severe acute respiratory syndrome (SARS). Methods Post-mortem tissue samples of organs (lungs, heart, liver, spleen, kidneys, pancreas, stomach ) were obtained by needle biopsy from four SARS patients who died in middle and late stages 3-5 weeks after the onset of the disease. The pathological samples were studied by light and electron microscope, immunohistochemistry, histochemistry and indirect immuno-fluorescent antibody test. Results The main pathological features were early interstitial pulmonary fibrosis or organizing pneumonia. Fibroblasts were increased in the interalveoli septa and young connective tissue was found to fill the alveoli. Diffuse alveolar damage (DAD) with alveolar pneumocytes proliferation and an increase in macrophages were found. Desquamative alveolitis also existed at the same time. Squamous metaplasia and syncytial giant cells with multinuclei could be seen. CD3 + and CD20 + lymphocytes were markedly decreased and CD68 + macrophages and S-100 + dendritic cells increased in spleen. Proliferation of bone marrow cells became restrained . Hepatocytes were vacuolated with fatty degeneration. Electron microscopy showed the presence of coronavirus-like particles 80-60nm in diameter enveloped in the cytoplasm of the type Ⅱ pneumocytes, endothelial cells and lymphocytes. Conclusions A novel coronavirus is the cause of the newly recognized severe acute respiratory syndrom (SARS). The main target organs are lung and immune system. Different pulmonary pathological features were found in patients dying from the disease in different stages. All of specimens showed positive reaction of SARS-fluorescence antibody.

Objective To study the relationship between sICAM 1,sVCAM 1,TNF ?,TNFR Ⅰ,TNFR Ⅱ and pathogenesis of vasculitis.Method The serum levels of TNF ?,TNFR Ⅰ,TNFR Ⅱ,sICAM 1 and sVCAM 1 were detected by ELISA and their levels between patients with vasculitis and controls were compared.Results Compared with the controls,the serum level of TNF ? was lower,the levels of TNFR Ⅰ,sICAM 1 and sVCAM 1 were higher in the patients with vasculitis,and there was no difference of TNFR Ⅱ between the two groups.Conclusion The low level of TNF ? suggests that this factor may not play a role in these patients,or its role was counteracted by its receptors—sTNFR,whose level was higher in patients with vasculitis.sICAM 1 and sVCAM 1 may play a significant role in the pathogenesis of vasculitis.

Objective To explore the causes and treatment measures of hyponatremia after liver transplantation. Methods The clinical data of 27 patients with hyponatremia after liver transplantation were analyzed retrospectively. Results Among the 27 patients, postoperative hyponatremia occurred in 25 cases in about one week, and preoperative hyponatremia occurred in 2 cases and severe ~hyponatre -mia occurred immediate after operation. Acute hyponatremia occurred in one case. Blood natrium was 130 to 135 mmol/L in 10 cases, 120 to 130 mmol/L in 12 cases and less than 120 mmol/L in 5 cases. The levels of blood potassium, phosphor and calcium were all normal. Urinary natrium, potassium and chlorine levels were all normal. The ascites natrium level was higher than blood natrium at the same time. Hyponatremia was treated by supply of hypertonic saline via gastrointestine an/or veins. Conclusion Various causes could result in hyponatremia after liver transplantation. The hyponatremia was treated by supply of hypertonic saline constantly and slowly.
