Objective To compare adaptive support ventilation (ASV) and pressure-controlled assist/control ventilation (PCMV) and evaluate the clinical effects of ASV. Methods 12 cases of acute respiratory failure patients induced by all causes were selected in the study. All patients with breathing independently underwent endotracheal intubation. The patterns of mechanical ventilation was PCMV-ASV-PCMV. the two settings of PCMV were uniformity. With ASV mode mechanical ventilation,we adjusted the percentage of minute ventilation (MV%) and ideal body weight (IBW) of patients,so as to reach the same minute ventilation volume of PCMV. We compared the blood gas,respiratory mechanics,work of breathing(WOB),airway occlusion pressure (P0.05). Compared with the first of PCMV,various indicators and blood gas of ASV had no significant difference,work of breathing (WOB),airway occlusion pressure (P=0.1) and inspiratory pressure time product (PTP) were significantly lower (P0.05). Conclusion ASV can get similar goals with conventional ventilation,and reduce patient′s effort and the central respiratory drive.

Objective To investigate the effect of preoperative regional intra-arterial chemotherapy on apoptosis and apoptosis-regulating genes in advanced breast cancer.Methods 56 patients were divided into 2 groups:Preoperative regional intra-arterial chemotherapy group(treatment group,28 cases)and non-preoperative chemotherapy group(control group,28 cases).Apoptotic cells were examined by TUNEL and bcl-2 expression,and bax was detected by immunohistochemical techniques.Results Apoptotic index(AI)of breast cancer in the treatment group was 8.74%,while that of the control group was 4.65%.The bcl-2 expression in treatment group was 0.68?0.06,while in control group was 2.24?0.36.Expression of bax in treatment group was 0.72?0.06,while in control group was 0.38?0.04(P

Objective To study the effective methods for extraction of clenbuterol from biological material. Methods Clenbuterol in blood samples was extracted with 5 different methods,the extracts from various extraction methods were determined by gas chromatography-mass spectrometry(GC-MS?雪. The efficiency of 5 extraction methods was compared with each other. Results The standard curve showed good linear relationship with a range from 0.01-10.0 mg/L clenbuterol hydrochloride(r=0.999 9?雪. The detection limit was 0.005 mg/L. After adding 1.0 ?g/ml clenbuterol hydrochloride into blood sample,the blood sample was immersed and extracted in 0.01 mol/L HCl and absolute alcohol.The extracts were extracted by chloroform at pH value of 11. The average recovery and RSD of this method were 96.5% and 5.21% respectively(n=6?雪. Conclusion The method showed easy operation and reliable results ,it was suitable for determination of clenbuterol in biological material without deviation.

The paper starts with a study of problems existing in current fundamental computer course assessment in Traditional Chi-nese Medicine ( TCM) colleges and universities and analyzes the competence-based procedural assessment of fundamental computer courses, points out that such an assessment, as the key factor in discipline construction and course construction, effectively guarantees the cultivation of versatile informatization professionals in the TCM field and is able to better promote the modernization of TCM.

Objective To investigate and compare the argumentativeness and attitudes towards thinking and learning between clinical nurses in general adult wards and wards for patients requiring particularity healthcare for the identification and development of core communication skills.Mettods “Argumentativeness Scale” and “Attitudes toward Thinking and Learning Survey” in Chinese were used to measure a convenience sample of 504 clinical nurses in seven hospitals.Results The scores in items reflecting rationality,positivism,empathy and acceptance in 247 nurses in wards for particularity heahhcare were significantly different from those nurses working in internal medical wards for adults with internal medical problems.Conclusions To develop harmonious interpersonal relationships in nurses,we should strengthen competencies in emotional regulation and rational thinking in nurses in wards for adults with in-ternal medical problems.

Objective To profile the subtypes of open reading frame 75(ORF75)of human herpesvirus 8(HHV-8)in patients with Kaposi's sarcoma,and to evaluate their relationship with clinical phenotypes and invasiveness of Kaposi's sarcoma.Methods Twenty-five paraffin-embeded tissue specimens of Kaposi's sarcoma were collected in the Department of Dermatology.People's Hospiml of Xinjiang Uygur Autonomous Region.DNA was extracted from these specimens.and nested-PCR was performed to amplify HHV-8 DNA followed bv bi-directional sequencing.Phylogenetic analysis was carried out by using the software DNASTAR,Clustal W program and PHYLIP package so as to identify the ORF75 subtyoe of HHV-8.Results HHV-8 DNA was detected in 21(84%)out of the 25 samples,and 7 cases of AIDS-associated Kaposi's sarcoma were all positive for HHV-8.Among the 21 patients carrying HHV-8 DNA,18 were positive for subtype A ORF75.3 for subtype C ORF75.The ORF75 subtypes had no significant correlation with the presence of mucosal lesions or clinical phenotypes of Kaposi's sarcoma.Conclusions The majority of patients with Kaposi's sarcoma in Xinjiang are infected with HHV-8 of ORF 75 subtype A and C.The ORF75 subtypes of HHV-8 have no correlation with the presence of mucosal lesions or clinical phenotypes of Kaposi's sarcoma.

Objective To explore a safe and efficient method for endotracheal intubation in mice.Methods 60 BALB/c mice were random divided into 2 groups, direct intubation under direct vision group, ( n = 30) and direct intubation under light by transillumination group ( n = 30).After successful tracheal intubation at the first judgment, mouse received a tracheal instillation of 3 mg/kg lipopolysaccharide.Bronchoalveolar lavage (BAL) was then performed three times with 0.8 ml sterile saline.Exudate cells were centrifuged and stained with Wright's fluid.Whether the intubation indeed succeeded was judged by the amount of neutrophil infiltrated into the lungs.The mortality after intubation, the time consumed for each successful tracheal intubation and the times of attempting for intubation in two groups were assessed to approve the efficiency of two techniques.Results Eight vs.two mice died within 24 hours in two groups respectively.The time consumed for each successful tracheal intubation and success rate for the first time for two groups were (92.6 ±23.4)s vs (64.0±20.1)s and 53.3% vs 86.7% respectively, which the consumed time was significantly different, while the final success rate almost the same for the two groups.Conclusion Both direct intubation under direct vision and intubation under light by transillumination can successfully intubate the tube into the trachea.But direct intubation under direct vision by transillumination is more efficient and safe in endotracheal intubation in mice.

Proliferation and migration of vascular smooth muscle cells (VSMC) are common pathological features of diabetic vascular complications,such as atherosclerosis and hypertension. Phenotypic modulation of VSMC is the basis for VSMC proliferation and migration. Therefore, studies on VSMC phenotypic modulation and its mechanisms in diabetes mellitus were of important significance to the prevention and therapy of diabetic vascular complications. This paper introduces VSMC phenotypic modulation and the underlying mechanisms in diabetes mellitus, and summarizes advance of studies on traditional Chinese medicine intervention upon VSMC phenotypic modulation, so as to provide reference for preventing and treating diabetic vascular complications with traditional Chinese medicines.
