[Objective] To discuss the clinical effect of nasal intestinal obstruction(IO) conduct catheterization on IO after ovarian cancer operation. [Method] Choose 25 cases of IO after ovarian cancer operation, randomly divide them into treatment group 10 cases and control one 15 cases. The control group take general nasogastric tube imbedding, the treatment group take nasal IO conduct catheterization;observe their post-operational complications and clinical cure effect. [Result] On complications in control group, 8 cases had electrolyte disturbance, with complication rate 53.33%, the part of clinical symptoms was re-lieved, the IO signs did not disappear or were reduced partly with X-ray;5 cases were cured clinical y, 3 had marked effect, 3 were effective, 4 had no effect, the total effective rate was 73.33%;for the treatment group, al cases were successful y imbedded and made decompression and drainage, there ’s no severe side effects after imbedding tube, the IO symptoms were effectively relieved;1 case was transferred to operation;6 cases were cured clinical y, 3 had marked effect, 1 was effective, 0 had no effect, the total effective rate was 100%;after cathetering, there ’s no severe complications, among which, 2 cases had electrolyte dis-turbance, the post-operation complication rate was 20%. The comparison of complication rate and clinical effective rate of both groups had difference of sta-tistical meaning. [Conclusion] Nasal IO conduct imbedding treating IO after ovarian cancer operation had more effect on relieving IO symptoms and reduc-ing complications than nasogastric tube.

Objective To investigate the expression patterns of osteopontin (OPN) , vascular endothelial growth factor-A (VEGF-A) , and hypoxia-inducible factor-1α (HIF-1α) in primary hepatocellular carcinoma (HCC) and determine the clinical significance of this differential expression profile.Methods Immunohistochemical staining of OPN, VEGF-A, and HIF-1α was carried out on primary HCC tissues from 90 patients, HCC-adjacent cirrhosis tissues from 20 of those patients, and normal liver tissues from 15 healthy controls.Correlations between expression levels and HCC clinicopathological characteristics were assessed by Spearman's correlation coefficient.Results The majority of HCC tissues showed positive immunostaining for OPN (69/90, 76.67%) , VEGF-A (64/90, 71.11%) , and HIF-1α (66/90, 73.33%) .OPN-and VEGF-A-positivity were significantly higher than the results from the cirrhosis tissues and normal tissues.HIF-1α-positivity was similar between the HCC and cirrhosis tissues, but both were significantly different from the normal tissues.The differential expressions of OPN, VEGF-A, and HIF-1α were significantly correlated with tumor thrombus, capsular integrity, tumor differentiation and stage, and metastasis (P<0.05) .Conclusion HCC tissues overexpress OPN, VEGF-A, and HIF-1α and this differential profile may be related to HCC progression.Future investigations of this triad of factors may provide novel insights into the biological characteristics of HCC and reveal important targets of molecular therapy.

Objective: To improve the diagnosis and treatment level of secretory otitis media (SOM) of children. Method :Clinical information of 80 children with SOM were colletcted and analysed. All of the 80 cases (144 ears)were treated by myringotomy with Grommet insertion. Among them, 30 cases by adenotonsillectomy. 10 cases by palatoplasty. Secretions of 54 ears were carded out by bacterial culture. Result:80 cases were followed up for 6 to 12 mothes. 120 ears of 144 were cured (83％) ,with hearing improved. The tympanograms and hearing threshold of pure tone were found to be normal. The Gram＇s positive and negative germs of bactevial culture were 20.7％ (6/29 samples ) and 24％ (6/25 samples ) respectively. Conclusion: Children with secretory otitis media should be treated as early as posible to improve the patients＇ hearing and develope their speech.

OBJECTIVE: To study the absorption and transport of pachymic acid (PA) isolated from the sclerotium of Poria cocos (Schw.) Wolf. in human intestinal epithelium. METHODS: By using Caco-2 (the human colonic adenocarcinoma cell lines) cell monolayers as an intestinal epithelial cell model, the permeability of PA was studied from apical side (AP side) to basolateral side (BL side) or from BL side to AP side. The PA was measured by reversed-phase high performance liquid chromatography coupled with UV detector at maximum absorption wavelength of 210 nm. Transport parameters and apparent permeability coefficients (Papp) were then calculated and compared with those of propranolol and atenolol, which were the transcellular transport markers for high and poor permeability respectively. RESULTS: The Papp values of PA were (9.50+/-2.20) 10(-7) cm/s from AP side to BL side, and (11.30+/-5.90) 10(-7) cm/s from BL side to AP side, respectively. Under the condition of this experiment, the Papp values were 1.45x10(-5) cm/s for propranolol and 4.22x10(-7)cm/s for atenolol. CONCLUSION: PA is transported through the Caco-2 cell monolayer in a concentration-dependent manner and the transport was linear with time. The absorption in apical to basolateral direction and secretion in basolateral to apical direction were poor and their Papp values were comparable to atenolol. Besides passive diffusion of PA, ATP is partially involved in its transport.

Rehabilitation treatment after cerebral infarction establishes on the basis of plastic changes in the central nervous system,which can compensate the functions lost in the affected brain regions.Neurorehabilitation training realizes neurological function recovery partly by enhancing cortical reorganization.Repetitive transcranial magnetic stimulation (rTMS) is a non-invasive approach that can effectively improve the cortical excitability,This article reviews the application of rTMS in the clinical studies of motor function recovery in patients with hemiplegia after cerebral infarction.

Objective To observe the effect of acupuncture on post-stroke belching. Method Ninety-six patients with post-stroke belching were randomized into a control group and a treatment group by random number table, 48 cases in each group. The control group was intervened by conventional Western medication, while the treatment group was by acupuncture in addition to the medication given to the control group. The blood Cl﹣ and Ca2﹢ contents, as well as the symptoms score and occurrence of adverse reactions were compared before and after treatment. Result After intervention, the blood Cl﹣ and Ca2﹢ contents increased and the symptoms score decreased to different extent in both groups; except for the blood Ca2﹢ content, there were significant differences in comparing all the parameters between the two groups after intervention (P<0.05); there was a significant difference in comparing the occurrence of adverse reactions between the two groups (P<0.05), and there were less adverse reactions in the treatment group. Conclusion Acupuncture can effectively control the post-stroke belching and reduce the happening of adverse reactions.

Objective To establish a liquid chromatographic-mass spectrometric method ( LC-MS/MS method ) for determination of dextrorphan in human liver microsome. Methods LC-MS/MS was adopted with carbamazepine serving as an internal standard.The separation was performed on Agilent ZORBAX XDB-C18 column (2.1 mm×50 mm, 3.5μm), with mobile phase consisting of 0. 05% formic acid methanol-0. 05% formic acid in gradient elution. Dextrorphan and carbamazepine were detected on multiple reaction monitoring(MRM)mode by transitions from precursor to production(m/z 258.1→199.1, 237.1→194.1). Results The linear range of dextrorphan concentration was 19.22-768 960 ng.L-1(r=0.999 8), and the lowest quantification limit was 19.22 ng.L-1.The relative recoveries were 94.02%-98.74%, and the RSDs of intra-day and inter-day were within 10%.IC50 of psoralen on CYP2D6 was 0.6μmol.L-1. Conclusion The LC-MS/MS method is proved to be rapid, sensitive and reproducible, psoralen is a strong inhibitor of CYP2D6.

This study was carried out to determine the effects of mild iron deficiency anemia (IDA) on physical work capacity (PWC) of 7-year-old children in Beijing. Ninety-three mild IDA children and thirty-seven well-to-do children served as volunteer subjects. Finger blood samples were obtained for Hb, FEP, FEP/Hb, SF determination; PWC data were assessed by measuring PWC 170, R.PWC170, Workload Heart Rates (W.HR), estimated Vo2max before, in the middle, and after treatment, respectively. After the mild IDA children were cured with iron supplement (300mg ferrous sulfate per day) for 60 days, their values of Hb, FEP, FEP/Hb, SF changed significantly from original 10.5g/dl, 41.8ng/dl, 4.6?g/g, 13.2ng/ml to 12.5g/dl, 24.1?g/dl, 2.0?g/g, 75.7ng/ml respectively (P
