Laparoscope has been widely recognized as a treatment of distal gastric cancer.Totally laparoscopic distal gastrectomy and laparoscopy-assisted distal gastrectomy are two main types of laparoscopic distal gastrectomy.Apart from a smaller incision,some other advantages which totally laparoscopic distal gastrectomy has is the key point for further study.The thesis aims to compare totally laparoscopic distal gastrectomy to laparoscopy-assisted distal gastrectomy,and to analyze the characteristic in the aspect of operation time,the degree of pain,postoperative complications and the time of gastrointestinal recovery via collecting a great quantity of literatures.

Mesenchymal stem cells (MSC) is able to differentiate into a variety of epithelial cells,such as alveolar epithelium,tubular epithelium and corneal epithelial cells in vivo and in vitro under the given condition.After transfusion,MSC can effectively repair the injured lung epithelial cells,and relieve inflammation.MSC can also repair the renal tubular cell damage by reducing renal interstitial infiltration of inflammatory cells,promoting regeneration of renal tubular epithelial cells and inhibiting of apoptosis; Biological cornea can be available constructed by using MSC,which can availably repair the injured ocular surface.In the other hands,MSC can express keratinocyte growth factors and other cytokines,promoting limbal stem cell proliferation.In addition,MSC can also differentiate into pancreatic ductal epithelial cells,endometrial epithelial cells,spermatogenic epithelium and human retinal pigment epithelium.MSC has great application potential in epithelial diseases,and provide a good and effective choice in treatment of some epithelial diseases.

Primary hypophysitis includes 3 subtypes:lymphocytic,granulomatous and xanthomatous hypophysitis. The primary hypophysitis has a low morbidity and the final diagnosis is mostly determined based on the pathological findings after operation.Now it is considered as an organ specific autoimmune disease.Its clinical manifestations and imaging features are similar to hypophyseal tumor,but the endocrine and pathologic features are different.Glucocortieoid pulse therapy and surgery are the two methods of treatment.

Objective To analyze the language structure of nursing records and the application of defined vocabulary in nursing records of community child care,and to explore the possibility of structuralization and standardization of community nursing records by researchers' consulting International Classification of Nursing Practice (ICNP(R)2.0).Methods Convenient sampling method was used.A total of 432 handbooks about child health care were extracted from three community health service centers in Liaoning province.By analyzing the nursing records,the vocabulary was selected,and a coding book was built.Then researchers compared them with ICNP(R)2.0 Chinese version.Results Totally 567 terms were extracted.All phrases in nursing records about community child health care can be classified into three categories and seven shafts,which were nursing phenomenon,nursing action and nursing outcome.Our community nursing records about child health care could not fully meet shaft level of nursing record writing requirements from the International Council of nurses.Only 146 records were labeled as perfect fit with ICNP(R)2.0 terminology,223 records as not fit at all.The difference of different levels of suitability distribution about nursing phenomenon,nursing action and nursing outcome had statistically significant difference.Words of able to adapt and can't adapt about nursing action had larger proportion.Words that can't adapt about nursing phenomenon and nursing outcome had larger proportion.Conclusions There is still certain gap between domestic nursing records and ICNP(R)2.0 terminology.The list of terms from comparison nursing records about community child health care with ICNP(R)2.0 can lay the foundation for nursing language system structure and perfect community nursing record language in our country.

Aim To explore the concentration range of organic solvent which can both effectively increase solubility of the difficult soluble medicine monomer, and have low toxicity to cells, and to clarify the influence of different concentration of ethanol on curcumol efficacy.Methods Different DMSO and ethanol concentrations were diluted in culture medium and incubated with cells A549, NCI-H460, NCI-H1299, NCI-1650, LTEP-a2 and SPC-A1 for 12 h, 24 h, or 48 h, cell viability was tested by a colorimetric assay with 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyl tetrazolium bromide(MTT), and different concentrations of ethanol with/without different concentrations of curcumol were also prepared with culture medium, then incubate with A549 and NCI-H460 cells for 24 h, and cell viability was tested by MTT as well.Results Within 48 h the solution with 0.008(V/V) DMSO or less had no significant effect on the cell A549 compared with control group, for NCI-H1650 the concentration was 0.004(V/V) or less, for NCI-H460 the result turned to be 0.002(V/V) or less, and the solution with DMSO below 0.001(V/V) had significant effect on the three other cells, NCI-H1299, LTEP-a2 and SPC-A1.While within 48 h, the liquor with 0.004(V/V) ethanol or less did not exhibit significant cytotoxic effect on the cell A549, for NCI-H460 and NCI-H1650 the result of ethanol concentration became 0.002(V/V) or less, for NCI-H1299 the data was 0.001(V/V) or less, and the liquor with ethanol below 0.001(V/V) showed significant cytotoxic effect on LTEP-a2and SPC-A1.When the proportion of ethanol in solution was below 0.01, it has no cytotoxic on cell A549 and NCI-H460, and the curcumol solution prepared with this kind of ethanol solution only represented the efficacy of curcumol on the cells.Since the solution with 0.01(V/V) ethanol dissolved the curcumol better, the cell viability changed from about 100% to about 35%.Conclusions Different organic solvent expressed different toxicity to the same cell, and the sensitivity of different cells to one organic solvent is dissimilar.and DMSO could be the optimum solvent for A549 and NCI-H1650, while the optimum solvent of NCI-H1299 is ethanol, for NCI-H460 it could be both and DMSO and ethanol, and DMSO and ethanol is not suitable for LETP-a2, SPC-A1 to be solvent.

Objective To evaluate the use of LigaSure vessel sealant system on hemorrhoidectomy for the patients with grade 3 and grade 4 hemorrhoids. Methods Sixty five patients with hemorrhoids (41 males and 24 females), among whom 46 cases were grade 3 and 19 cases were grade 4, underwent hemorrhoidectomy under local anesthesia with the use of LigaSure vessel sealant system. The time consumed for operation and the blood volume lost during and after operation were recorded. Postoperative pain was assessed by means of visual analog score (1-10). The patients were followed up for 2 months. Results The operations were performed successfully in all patients. The time consumed was 5-25 minutes (9.7?4.6 minutes). The pain scores at 4 hours and 24 hours after operation were 1-7 (2.7?1.7) and 0-5 (1.9?1.3), respectively. On the third day after operation, only 4 cases had a pain score of 3 to 5, in the remaining 61 cases the score was under 3. On the seventh day after operation, only 5 patients had pain scores of 1 to 3. No patients complained pain about 2 months later. The volume of blood loss in 9 cases was less than 15ml (15.8%), and in the remaining 56 cases there was no apparent blood loss during the operation. Only one patient was re-operated for bleeding after operation, and in 18 (27.7%) patients there was only oozing of blood. Mild incontinence occurred in 6 patients shortly after operation, and no severe complications occurred. Conclusions LigaSure vessel sealant system shows the advantage of good haemostatic effect, less time consuming for operation, and less pain after operation for the treatment of patients with Grade 3 and Grade 4 hemorrhoids.

Objective To investigate the relaxant effect of salanic acid A isopropyl ester(isopropyl 3-(3,4-dihydroxyphenyl)-2-hydroxypropanoate)and its mechanism.Methods Isolated rat pulmonary artery was perfused and the tension of the vessel was measured.To observe the relaxant effect of salianic acid A isopropyl ester on the pulmonary artery precontracted by noradrenaline(NE)and the role of endothelial cell and vascular smooth muscle cell on vasodilation.Results Salianic acid A isopropyl ester relaxed the endothelium-intact artery precontracted by NE in a concentration-dependent manner,and the effect was depressed with denuded endothelium.Salianic acid A isopropyl ester right-shifted the concentration-response curve of KCl and suppressed the contractions induced by NE and CaCl2 in the Ca2+-free-K-H solution.The relaxant effect of salianic acid A isopropyl ester was inhibited by N?-nitro-L-arginine methyl ester hydrochloride(L-NAME),Indometacin,CsCl,Tetraethylammonium(TEA),Glibenclamide,and BaCl2,but not that by Propranolol,Metoprolol,and Salbutamol.Conclusion Salranic acid A isopropyl ester could significantly relax the pulmonary artery of rats,which may derive in part from endothelium.The relaxant effect of salianic acid A ispropyl ester may relate to NO pathway,prostacyclin(PGI2)pathway,calcium channel,and potassium channel.
