AIM: To investigate the influence of Streptococcus pneumoniae on the apoptosis of alveolar epithelial cell and the modulation of caspases-3 on apoptosis. METHODS: A study was undertaken to determine whether Streptococcus pneumoniae infection induced the apoptosis of A549 and facilitated the expression of pro-inflammative cytokine. After inhibited by siRNA, the expression of caspase-3 and apoptosis grade in A549 were determined. RESULTS: Streptococcus pneumoniae contributed to alveolar epithelial cell apoptosis in a time-dependent manner. Streptococcus pneumoniae facilitated the expression of caspase-3 and IL-6 in A549, while depressed IL-10 concentration in culture medium. SiRNA directly decreased the expression of caspase-3 to rescue A549 from apoptosis but not affected IL-6 and IL-10 concentration. CONCLUSION: caspase-3 gene silencing rescues epithelial cells from apoptosis initiated by Streptococcus pneumoniae infection.

Objective: To explore the antagonism of selenium enriched Spirulina platensis(Se-SP) to hepatocirrhosis by enhancement of cell proliferation and selenoenzyme activity.Method: The male SD rat hepatocirrhosis model was induced by thioacetamide(TAA),and Se-SP was supplemented.Hepatic histological analysis was performed and relative content of collagen(RCC %) was estimated using IBAS 2000 system after Masson’s staining.Glutathione peroxidase(GSH-Px),thioredoxin reductases(TR) and malondialdehyde(MDA) in hepatocyte as well as hyaluronic acid(HA) in serum were determined.Expression index of proliferating cell nuclear antigen(PCNA) in hepatocytes was detected by immu-nohistochemistry,and the level of synthesis of DNA in regenerative hepatocytes was analyzed by radio-immunity for incorporation of 3H-TDR.Results: Hepatocirrhosis was induced by TAA at 9w of the expeiment,and the obvious antagonism of Se-SP to hepatocirrhosis was obsewed after Se-SP supplementa-tion.12.5% rats of Se-Sp group were completely recovered at 15w of the experiment(6w after withdrawal of TAA).GSH-Px and TR activity in hepatocytes as well as PCNA and 3H-TDR incorporation rate in hepatocytes were obviously enhanced(P

AIM: To investigate the influence of tumor necrosis factor-α (TNF-α) induced apoptosis through knocking down Bax gene by RNA interference (RNAi) in human alveolar type II epithelial cells (A549). METHODS: A549 cells were cultured in vitro and divided into 4 groups according to RNAi treatment: control group, TNF-α treated group, Bax siRNA group and control siRNA group. Chemically synthesized small interfering RNA (siRNA) directed against human Bax gene was transfected into A549 cells by cationic liposome. The effect of RNAi was investigated by reverse transcription PCR, Western blotting and immunohistochemisty, and the rate of apoptosis was investigated by flow cytometry. RESULTS: Bax gene was knocked down effectively in Bax siRNA group (P<0.05). Apoptosis was induced by TNF-α in TNF-α treated group and control siRNA group. However, it was abolished in Bax siRNA group by the downregulation of Bax gene compared to TNF-α treated group and control siRNA group (P<0.05). CONCLUSION: This result suggests that Bax gene has a significant role of pro-apoptosis in A549 cells and knocking down Bax gene by RNAi can effectively inhibit TNF-α-induced apoptosis in A549 cells.

BACKGROUND: The effect of cognitive therapy on psychological stress is not remarkable and optimal. Some psychocatharsis through physical activities cannot be accepted by many clients.OBJECTIVE: To explore an effective method to treat and relieve psychological stress.DESIGN: A controlled (the blank control and the self-control) observation study and single blind trial.SETTING: Department of Preventive Medicine, Medical College of Jinagsu University.PARTICIPANTS: Clients who suffered from emotional suppression or nervous stress would be tested with "psychological stress test". Forty clients, with scores over 5, were selected as the subjects. They were randomly divided into two groups matching of ages and scores: control group (n=20) and experimental group (n=20).METHODS: Clients in the control group were treated with common cognitive therapy by means of talking, and those in the experimental group accepted a sing a song loudly therapy. The song named as Qinghai-Tibet Plateau was selected for the treatment. The clients were requested to sing the song loudly in order to release their stress and vent their repression.The psychologist used the language introduction by background music to make a client under a special kind of psychological situation and emotional state when the music was played for one to two times. Then the psychologist would turn up gradually the volume of sound to the maximum when the music was played for the third time. The volume from the VCD would overwhelm that from the client's voice in order to cover up the singer's shyness. The client sung the song of Qinghai-Tibet Plateau loudly for four to five times. The therapeutic room was required to have a blanch curtain.The sound insulation also was required. The soundscape of the loudspeakers should be wide. The power magnifier should be strong. The loudspeaker should be high fidelity. The questionnaire of psychological stress test was adopted in both groups before and after therapy respectively. It had 30 items for the self-diagnosis of symptoms. The client was diagnosed as a low stress if his or her score reached 5, 11-20 as sever stress, and above 21 as adaptability disorder.MAIN OUTCOME MEASURES: Scores of stress level were observed before and after therapy in both groups.RESULTS: The scores in the control group before and after therapy were approximately the same (15.6±5.3 vs 14.7±4.8, t=1.739, P ＞ 0.05). The scores in the experimental group after therapy was significantly lower than those before therapy (11.6±5.8 vs 15.5±6.1, t=9.863, P ＜ 0.05). After therapy, the scores in the experimental group were significantly lower than those in the control group (11.6±5.8 vs 14.7±4.8, t=4.811, P ＜ 0.05).CONCLUSION: Sing a song loudly is an effective method that is easy to operate in treating psychological stress.

Objective To investigate the conditions of diabetes-related knowledge as well as the influencing factors in elderly people in Changchun so as to provide basis for regulation of health education policy.Method A total of 400 community elderly people in Changchun involved in the survey by questionnaire for investigating the knowledge on diabetes and the influencing factors. Results The elderly people in the community in Chuangchun knew much better about the typical symptoms,diet and treatment by 74.0%,80.8%and 75.8%,respectively,but they knew little about the causes of the disease and complications by 52.7%and 25.7%respectively.The factors influencing their acquisition of diabetes related knowledge included education level,income and disease condition.Conclusions The elderly people in the communities lack diabetic knowledge,which is unbeneficial for the prevention and control of diabetes.Therefore,it is a need to strengthen diabetes-related knowledge education in order to prevent and reduce the complications.

ObjectiveTo explore the clinical efficacy of Ningmitai capsule for treatment of patients with diabetic urinary tract infection.Methods A total of 100 diabetes patients with urinary tract infection from Zunyi First People's Hospital in Guizhou Province and Longkou Family Planning Service Station in Shandong Province wereenrolled in the study and randomly divided into control and treatment groups after they were informed and gave consent. With basic therapy to lower blood glucose, 65 cases in the treatment group were treated with Ningmitai capsule(4 granules/time, every grain of 0.38 g), while another 35 cases of the control group were given Sanjin tablets (4 granules/time, every grain of 0.29 g), 3 times a dayfor 2 weeks in both groups. Before and after treatment, the clinical effect, blood routine, urine routine, blood glucose, negative conversion ratio of midstream urine bacteria culture and tradition Chinese medicine syndrome curative effect in both groups were observed.Results The total effective rate of treatment group was significantly higher than that of the control group〔88.52%(54/61) vs. 70.59%(24/34),P<0.01〕. Before treatment, the differences in red blood cell(RBC) and white blood cell(WBC) count in urine samples as well as RBC, WBC, hemoglobin(Hb) and glucose in blood samples had no statistical significance in the comparisons between the two groups(allP>0.05). Compared with those before treatment, after treatment, the urinary RBC and WBC were decreased in treatment group, while in control group WBC was decreased but RBC increased, and in the comparisons of above indexes between the two groups there were statistical significant differences〔RBC(cell/μL): 1.99±0.59 vs. 9.11±3.76, WBC(cell/μL): 23.09±6.18 vs. 63.72±25.76, bothP<0.05〕. The blood RBC was significantly lowered after treatment in control group(×109/L: 3.93±0.40 vs. 4.02±0.39,P<0.05). In both groups, after treatment, WBC, Hb and glucose in blood were reduced in comparisons to those before treatment, and no statistical significant differences were found(allP>0.05). Negative conversion ratio of midstream urine bacterial culture in treatment group was significantly higher than that in control group〔80%(4/5) vs. 0(0/2)〕. Syndromes of traditional Chinese medicine were ameliorated at different degrees after treatment in both groups. The effectiveness of treatment group on urinary urgency, yellowish turbid urine and swelling pain in lower abdomen were obviously more valid than that of control group〔urinary urgency: 90.0%(54/60) vs. 61.8%(21/34), yellowish turbid urine: 75.0%(39/52) vs. 47.6%(10/21), swelling pain in lower abdomen: 74.5%(35/47) vs. 70.6%(12/17),P<0.05 orP<0.01〕, but other symptoms were similar in the two groups(allP>0.05).ConclusionThe clinical efficacy of Ningmitai capsule is better than that of Sanjin tablet for treatment of patients with diabetic urinary tract infection, and no adverse reaction has been seen in clinical observation.

OBJECTIVE:To investigate the cognition of clinical pharmacists on the clinical pharmacy practice and their profes-sion,and provide reference for further developing clinical pharmacy practice. METHODS:A questionnaire was designed,and ran-dom sample was conducted for the clinical pharmacists from 30 secondary and tertiary hospitals in Shanghai,and the investigation results were analyzed statistically. RESULTS:Totally 130 questionnaires were sent out,and 102 were effectively received with valid response rate of 78.46%. 94.11% of the investigated subjects were willing to be a clinical pharmacist,but 17.65% of them consid-ered that they were incompetent for their work;29.41% of them thought the current situation of clinical pharmacy practice was not ideal;all the respondents considered that the clinical pharmacist system should be implemented in medical and health institu-tions;the cognition and evaluation of investigated subjects in tertiary hospitals on clinical pharmacy practice and their profession was generally higher than those in secondary hospitals(P<0.05). CONCLUSIONS:The clinical pharmacists in medical and health institutions in Shanghai showed high cognition on their profession,and the clinical pharmacy practice has already made some achievements,but many work still need to be improved. Therefore,clinical pharmacists should continuously study their profession-al knowledge and improve their professional skills and quality;hospitals and universities should strengthen the subject construction and personnel training of clinical pharmacy and deeply carry out the clinical pharmacist system;health administration departments should strengthen the related laws and regulations of clinical pharmacy;colleges and universities should strengthen the discipline construction and personnel training.

AIM: Tumor necrosis factor-?(TNF-?) participates in the establishment of inflammatory lesions in pneumonia.High production of TNF-? may relate to the severity of pneumonia.There have already been several studies examining the association between pneumonia and single nucleotide polymorphisms(SNPs) that affect cytokine productivity.SNPs of TNF-?,-1 031,-863,-857,-308 and-238 have been identified.The variant alleles of these SNPs have suggested to be related to high TNF-? production and the severity of pneumonia.Therefore,the aim of this study is to examine the association between the severity of pneumonia in Chinese and the following SNPs: five in the TNF-? gene promoter(-1 031,-863,-857,-308,-238).METHODS: A total of 117 Chinese individuals were enrolled in this study.They were 67 patients with pneumonia and 50 healthy subjects.TNF-? was genotyped by polymerase chain reaction-restriction fragment length polymorphism for all subjects.The frequency distributions of genotypes in different groups were analyzed by SPSS 11.5 program.RESULTS: Frequency of subjects who carried at least one variant allele in TNF-?-1 031,-863,-857,-308,-238 SNPs among pneumonia patients was significantly higher than that in healthy subjects.And frequency of subjects who carried variant allele in TNF-?-863,and-308 SNPs among severe adult community acquired pneumonia patients was significantly higher than that in common pneumonia patients.CONCLUSION: TNF-?-863 and-308 SNPs appear to be associated with severe adult community acquired pneumonia in Chinese populations.
