In the present study, we observed the effects of cholinergic enhancement by pyridostigmine (PD), a cholinesterases inhibitor, on GH release in both normal (n = 13) and GH deficient children and adolescents (n = 8). Responses of GH to insulin hypoglycemia were also observed. In the normal subjects, PD-induced serum GH peak levels were significantly higher than that induced by insulin (P

Objective To study the surgical treatment of major blood vessels invaded by tumors in order to raise the resection rate and postoperative survival rate. Methods Clinical data were analyzed on 26 patients undergoing (resection) of tumors along with reconstruction of major blood vessels from October 1998 to February 2004. Results Tweety-three cases were followed up for 2～65 months with median 42.8 months. Doppler ultrosonography and CTA examination were performed respectively during the follow-up process.In 5 patients with carcinoma of the head of pancreas who had inferior vein cava replaced and in 1 patient with cholangiocarcinoma who had portal vein replaced,3 were complicated with carcinoma embolism formation at 3,12 and 15 months respectively after surgery,(postoperative) graft patency was 50%;all of the 6 patients had recurrence of the tumor at 3,6,8,12,24 and 31 months respectively after surgery.Seven patients with tumor in pelvic cavity or in posterior space of peritoneum were followed up for about 2 years,1 of them had tumor recurrence ,but the graft kept patent,2 patients with sarcoma in the limbs were followed up for 1 year without tumor recurrence or vessel obstruction.Eleven patients with tumors in the neck were followed up for 3 months to 5 years without tumor recurrence or vessel obstruction. Conclusions (Combination) of resection of neoplasm and reconstruction of major blood vessels is safe,effective and practical method for patients with major wessels invaded by tumor.

ObjectiveTo explore the action of the psychointervension for older hypertensives in community.Methods50 older hypertensives were divided into the experimental group and the control group (with 25 cases in each group),the former received psychointervension combined body therapy and the later only received body therapy. A half of a year experiment period was made. Differences between two groups in blood pressure and SCL-90 before and after the experiment were compared and evaluated.ResultsThe mentation of older hypertensives is worse than the normal. There are distinct differences between two groups in the improvement of mentation and the stability of blood pressure (P<0.01). Conclusions It is an active effect to strengthen psychointervension for therapy of older hypertensives in community.

Objective To investigate the application and effect of nursing quality monitoring book in ICU.Methods Quality monitoring book was used,quality control management group was established,monitoring group leader was chosen and the writing method,content as well as tracking record method of quality monitoring book were all specified.Results After the use of quality monitoring book,the nursing quality rate inspected by nursing department increased from 94.54％ to 97.41％,and the difference was statistically significant (x2 =7.788,P ＜ 0.01 ).The nursing quality rate inspected by head nurse increased from 93.59％ to 96.15％,and the difference was statistically significant ( x2 =5.270,P ＜ 0.05 ).The incidence rate of nursing adverse events decreased from 2.5％ to 0.8％,and the difference was statistically significant ( x2 =5.722,P ＜ 0.05).Conclusions The application of nursing quality monitoring book has perfected the quality feedback system,can improve management efficiency and comprehensive quality,and reduce the occurrence of nursing adverse events.

OBJECTIVE To investigate the chemical constituents of the roots and rhizomes of Ligularia macrophylla.METHODS The compounds were isolated through repeated column chromatography on silica gel, polyamide, RP-18 and Sephadex LH-20. And the structures were elucidated on the basis of spectroscopic data (UV, IR, MS, 1H NMR, 13C NMR, DEPT and 2D NMR). RESULTS Four flavonol glycosides and two monoterpene glycosides were obtained and determined as rhamnazin-3-O-β-D-rutinoside ( 1 ), rhamnetin-3-O-β-D-rutinoside ( 2), rutin ( 3), afzelin ( 4), betulalbuside A (5) and 3,7-dimethyloct-1 -en-3,8-diol8-O-β-D- glucopyranoside (6). CONCLUSION All the compounds were isolated from this plant for the first time.

It is held by some of the researches that the "16 collaterals" is composed of the "15 collaterals" and "the major collateral of stomach". And it is included into the textbook that Xuli, the major collateral of stomach, is the pulsation point at the cardiac region. Xuli is often explained as the empty portion of the human body by many researches. Through analysis and summarization of the related theory of the major collateral of stomach, the above mentioned opinion is discussed. And the understanding on the major collateral of stomach is deepened. As a result, it is concluded that count the major collateral of stomach into the 16 collaterals together with the 15 collaterals is inadvisable. The real pulsation point at the cardiac region locates under the left breast. And the real meaning of Xuli is "extending in all directions".

The microstructure of cationic cyclopeptide (TD-34) treated Caco-2 cell membrane was observed, and we discussed the relationship between membrane structure and insulin transmembrane permeability. Atomic force microscope (AFM) was used to observe living cell membrane in air condition and tapping mode. Results showed that the surface of Caco-2 cell membrane treated with TD-34 lost its smoothness and nearly doubled its roughness. Apparent permeability coefficients (P(app)) of insulin in Caco-2 cell monolayers increased 2.5 times. In conclusion, AFM can be used to observe microstructure of cationic cyclopeptide treated cell membrane and cationic cyclopeptide enhanced insulin delivery across Caco-2 cell membrane by increasing membrane fluidity.

To understand the adverse drug reaction (ADR) induced by Mailuoning injection. 162 ADRs due to the drug were retrieved from national medical journals of 1988-2007 for statistics. It was shown that there was no relationship between ADR and dosage, but ADR appeared mostly in middle-aged and old groups, and more in male than in female. The occurrence of ADR was commonly within 30 min after injection. It involved injuries of various systems and organs. As for the 123 cases of allergy, 38 were anaphylactic shock (accounting for 23.46%), two people died. ADR characterized by immediate type on initial use and tachy type. It should be paid more attention to the Mailuoning injection for the immediate hypersensitivity reaction (such as anaphylactic shock).

After comparing the varieties of parameters in batch culture under different dissolved oxygen tension by Bacillus pumilus, we found that the demand of cell on oxygen in different phase isn' t consistent. Based on the analys is of the metabolic pathway of oxygen and the mechanism of the effect of dissolved oxygen tension on fermentation of D-ribose, a two-stage oxygen-supply control mode was proposed and experimentally proved to be available. High ribose yield and high glucose consumption rate were achieved during whole process for 44h, and the ultimate ribose concentration and cell concentration were 5.0% and 18.8% higher than former respectively.
