Alteration in gastric emptying may play a role in the pathogenesis of many diseases.And various methods to measure gastric emptying have been developed.Nine procedures for the assessment of gastric emptying were reviewed in this paper including intubation test,radiology method,absorption test,real time ultrasound,breath test,radionuclide technique et al .Among all of these methods,radionuclide technique is considered as the good standard method.

Observations are made on 1208 postoperative cases and logistic analyses are centered on the risks related to postoperative hospital infections.It is discovered through observations that the rate of hospital infections is 7.5%.The infected parts are mainly the lower respiratory tract and the inci- sion.Logistic analyses of the risks indicate that postoperative hospital infections are related to preopera- tive hospitalization duration,the time span of endotracheal intubation,trachealaryngotomy and the re- tention of pleural drainage,type of operation,operational duration,and postoperative complication. Thesefore,hospitals should look seriously at the postoperative infection risks and take important steps to control them.

Conclusion The patients with chronic obstructive pulmonary disease with respiratory failure choose conventional and Atrovent aerosol inhalation treatment effect significantly, can effectively improve the patient clinical symptoms and adverse reactions are few and deserve to be widely used in the treatment of chronic obstructive pulmonary diseaseand respiratory failure patients.

Physical constraints is a commonly protective medical measure in clinic. if lack of humanistic nurs-ing in the use of the process,then it will give the patient a physical,psychological and ethic issues. This paper sum-marized the research status of humanistic nursing and physical constraints and concluded the humanistic nursing measures before, during, and after physical constraints, and thus to provide a reference for the further implementa-tion of humanistic nursing.

Tumor angiogenesis, resulting from the imbalance of angiogenic cytokines and angiogenesis inhibitors, is crucial for tumor growth and metastasis. As a new field of cancer therapy, tumor anti-angiogenesis therapy with regard to abrogation of tumor vasculature has become an important anti-tumor strategy. Gene therapies have the potential to provide antiangiogenic mediators specifically targeted to organs containing tumors and make a great improvement in this therapy. This article reviews the current understanding of tumor angiogenesis, with a focus on gene therapy in this field.

Objective: To investigate the awareness and training needs of incontinence-associated dermatitis (IAD) among clinical nurses, so as to provide insights into the standardization of clinical nursing of IAD. Methods: Clinical nurses with more than one year of service in Lanxi People's Hospital were selected as study subjects in October 2021. The demographics, awareness of IAD knowledge and training needs were collected using a self-designed questionnaire. The age-, duration of service-, academic degree-, professional title- and department-specific awareness of IAD knowledge was analyzed. Results: A total of 420 questionnaires were allocated, and 409 valid questionnaires were recovered, with an effective recovery rate of 97.38%. All respondents were females, with a mean age of (37.68±4.82) years, and a mean service duration of (18.72±3.46) years. There were 199 nurses with a primary title (48.66%), 169 nurses with a intermediate title (41.32%), and 41 nurses with a senior title (10.02%). There were 217 nurses with a bachelor degree or above (53.06%), and 208 nurses from internal medicine and surgery departments (50.86%). The overall awareness of IAD knowledge was 74.57% among the respondents, and the awareness rates of IAD definition, the difference between IAD and pressure ulcers and influencing factors of IAD were 86.06%, 83.37% and 82.15%, respectively. The nurses at ages of 41 to 53 years (89.01%), having a senior title (94.24%), with a nursing duration of 21 years and longer (92.97%) and participating in IAD training during the recent one year (77.41%) had a high awareness rate of IAD-related knowledge. There was a high proportion of needs for training on basic IAD-related knowledge (396 nurses, 96.82%). Conclusions The awareness of IAD knowledge requires to be improved among clinical nurses. The training on IAD knowledge is recommended to be improved.

Objective To investigate whether gastric hypersensitivity exists in functional dyspepsia patients, and to observe the number of mast cells in proximal gastric mucosa in gastric hypersensitivity patients and the change of mast cell degranulation after stimulation so as to evaluate the role of mast cells in gastric hypersensitivity. Methods Gastric sensation threshold was determined using barostat in 40 functional dyspepsia (FD) patients and 15 controls. Twenty three patients were divided into two groups on the basis of perception threshold: hypersensitivity group (FD H) and normal sensation group (FD N). Mast cells were stained by immunohistochemistry method, mast cell number was calculated by microscopy and the average optical density valves( A ) of mast cell were obtained by microspectrophotometry (MSP). The ultrastructure of mast cell was observed under electromicroscopy. Results Gastric sensation threshold (i.e. perception, discomfort and pain threshold) was significantly lower in FD patients than in controls ( P

Objectives This study was to evaluate GABA BR (including GABA BR1 and GABA BR2) expression in human gastric cancer. Methods Thirty randomly chosen patients with gastric cancer who underwent surgical treatment were entered into the current study. Immunohistochemistry was carried out to determine the expression of GABA BR. Results Immunohistochemistry analysis showed that the scores of GABA BR1 and GABA BR2 in human gastric cancer tissue increased apparently compared with the adjacent normal tissue(P

Objective To explore the inhibitory effect of genistein on oncogene HER-2/neu-overexpressing breast cancer xenograft tumors and its relationship with urokinase type plasminogen activator (uPA) expression. Methods HER-2/neu-overexpressing MCF-7 human breast cancer cells (MCF-7/HER-2) were generated by transfecting the HER-2/neu negative MCF-7 cells with HER-2/neu cDNA. MCF-7/HER-2 and MCF-7 xenograft models were established in BALB/c nude mice, and the nude mice with MCF-7/HER-2 xenograft were randomly divided into three groups: control group, genistein-treated group, and HER-2/neu antibody-treated group. The growth ability of xenograft tumors was analyzed by immunohistochemical staining with Ki-67 antibody, and uPA expression of xenograft tumors was analyzed by Western blotting. Results The growth ability and uPA expression were significantly higher in MCF-7/HER-2 xenograft tumors than those in MCF-7 xenograft tumors. MCF-7/HER-2 xenograft tumors treated by genistein or HER-2/neu antibody showed lower growth ability and uPA expression as compared with MCF-7/HER-2 xenograft tumors. Conclusion Genistein can inhibit the growth ability of HER-2/neu-overexpressing breast cancer xenograft tumors, which is associated with the uPA expression.

Objective To investigate the protective effect of gonadotropin releasing hormone agonist on ovarian function in patients with early stage cervical cancer.Methods80 cases ofadmitted patients with early stage cervical cancerfrom January 2015 to January 2016 in Yinzhou Second Hospital were selected, were randomly divided to observation group and control group.Patients in the observation group were retained ovarian resection, while giving the gonadotropin releasing hormone (GnRH) agonist treatment, the control group patients only with reservation of ovary resection and compared between the two groups before and after chemotherapy in patients with basal follicle stimulation hormone (bFSH) levels, serum anti Mullerian tube hormone (AMH) level, basic estrogen (bE2) levels, and the basal antral follicle number (bafc).ResultsThere were no significant differences in two groups of chemotherapy in patients with anterior bFSH and bE2 level, after chemotherapy, the observation group patients bFSH and bE2 level was significantly lower than that in control group (P<0.05) and chemotherapy after bFSH level of two groups of patients were higher than that in the chemotherapy before.bE2 levels were lower than those before chemotherapy (P<0.05);chemotherapy the number of patients in the two groups of AMH level and bafc without significant difference, after chemotherapy, the observation group AMH levels and bafc number were significantly higher than those of the control group (P<0.05) and chemotherapy after two groups of patients with AMH levels and bafc number lower than the chemotherapy before (P<0.05).ConclusionGnRH agonists can effectively protect the early cervical cancer patients with radical resection of ovarian reserve and ovarian reserve function, clinical application is worthy of further promotion.
