Aim To investigate the activation of prote-ase-activated receptor 2 ( PAR2 ) in regulation of the expression of epidermal growth factor receptor ( EGFR) and apoptosis of lung cancer ( LC) cells. Methods LC cells A549 and its EGFR-silenced counterpart were incubated in the medium added with tryptase. Quanti-tative RT-PCR and Western blotting were used to de-tect the expression of EGFR in A 5 4 9 cells . The apop-tosis and Bax/Bcl-xL of cells were also recorded. Re-sults Treating A549 cells with tryptase in the culture for 48 hrs resulted in a marked increase in the expres-sion of EGFR in A549 cells. Marked decreases in a tryptase dose-dependent manner in apoptotic A549 cells were detected in the presence of tryptase. Expo-sure to tryptase markedly decreased the levels of Bax and increased the levels of Bcl-xL in A549 cells, which were not shown in EGFR-deficient A549 cells. Conclusion Tryptase can increase the expression of EGFR in LC cell line, A549 cells, which protects A549 cells from apoptosis, increases Bcl-xL, and sup-presses Bax in A549 cells.

OBJECTIVE:To guarantee the reliability of cold chain drug storage device and the quality of the drugs in the hospi-tal. METHODS:The establishment and effects of drug cold chain monitoring platform in our hospital were introduced as well as re-lated improvement and measures. RESULTS:The cold chain monitoring platform was established in our hospital through equipping with related equipment, constructing platform network, determining monitoring point, setting early warning condition, etc. All-weather and real-time monitoring of temperature and humidity were realized for different districts of the hospital and different cold chain equipments. The platform could provide the information about operating condition of equipment,and complete drug re-frigeration temperature record;equipment failure could be dissolved in time based on early warning message. Through analyzing rea-sons of early warning message,the unqualified equipment was updated in time,which further improve the system and procedure of cold chain monitoring platform. Within 2 years after the implementation of the platform,53 sets of special refrigerator for drug were updated. Monthly early warning message and the rate of refrigeration equipment early warning decreased from 6869 and 100% in Sept. 2014 at the early stage of short message warning function to 1083 and 40% in Feb. 2016,respectively. CONCLU-SIONS:The establishment of drug cold chain monitoring platform guarantees the reliability of cold drug storage condition so as to ensure the quality of drug in the hospital.

Objective To investigate the pathogens of acute respiratory infection of children.Methods A total of 159 children with acute respiratory infection who were hospitalized in our department from August 2005 to January 2006 were involved in this study.The serum IgM antibody of 18 pathogens were detected by indirect immunofluorescence test.The 18 pathogens included respiratory syncytial virus(RSV),adenovirus(ADV),influenza A(H1N1,H3N2)and B viruses,parainfluenza viruses(PIV) type 1,2,3 and 4,coxsackie virus B1(CBV1),coxsackie virus A7(CAV7),echovirus(ECHO7),haemophilus influenzae(HI),klebsiella pneumoniae(KP),bordetella pertussis(BP),bordetella parapertussis(BPP) and legionella pneumophila serotype 1 and 12.Results The evidence of specific IgM was obtained in 103 of 159 patients(64.78%).Influenza A was found in 66 cases(64.08%),influenza B in 49 cases(47.57%),enterovirus in 26 cases(25.24%),RSV in 18 cases(17.48%),PIV in 11 cases(10.68%),and co-infection in 66 cases(64.08%),1/ 3 of them were co-infected with influenza A and B.Conclusions Viruses are the most common agents of acute respiratory infection.Influenza virus is predominant among them.

Objective To explore the effect of bacillus calmette-guerin (BCG)intervention on expression of costimulatory molecules of B7-CD28/CD152 and T lymphocyte apoptosis in asthmatic mouse.Methods Twenty-seven mice were randomly divided into:asthma model group,BCG treatment group and normal control group.The mice were sensitized by ovalbumin(OVA) and 100 g/L Al(OH)3 with intraperitoneal injection,challenged with atomization inhalation,then reproduced the asthmatic models.The BCG treatment group were treated with BCG(0.025 mg,merely) subcutaneous injection 3 times before sensitization(5,3,1 day).The normal control group were treated with 9 g/L saline water taking place of OVA and Al(OH)3.CD28,CD152,CD80 and CD86 were analyzed by flow cytometry in splenic lymphocyte suspension.T lymphocyte was cultivated from peripheral blood mononuclear cell.The apoptosis ratio of T lymphocyte was counted by Comet Assay.SPSS 10.0 software was applied to analyze data.Results Contrasting asthma model group with normal control group,CD28 was up regulated(t=3.94 P0.05),CD86 was up regulated(t=2.68 P0.05).Contrasting BCG treatment group with asthma model group,T lymphocyte apoptosis rate was higher(t=3.15 P

Objective To compare the clinical effect of drug-eluting stents implantation or pure balloon expansion for the treatment of patients with knee artery lesions. Methods Sixty-eight patients with knee artery lesions were randomly and voluntarily divided into the control group( n=34 )and observation group( n=34 ) . The patients in the control group were given balloon expansion treatment,while in observation group were implanted drug-eluting stents besides balloon expansion. Pathological changes of skin temperature,percutaneous oxygen partial pressure( TcPO2 ),ankle brachial index( ABI),and the recurrence rate of patients before and after treatment for 6 months and 12 months were recorded and compared. Results After 6 months treatment,TcPO2 and ABI in observation group were(35. 4 ± 4. 5)mmHg and 0. 85 ± 0. 04,significantly higher than that in control group(( 28. 2 ± 3. 5 ) mmHg and 0. 62 ± 0. 03 ),and the differences were statistically significant( t=2. 535,2. 185;P﹤0. 05). At 12 months after treatment,skin temperature,TcPO2,ABI in observation group were(32. 4 ± 4. 3)℃,(34. 3 ± 4. 2)mmHg and 0. 80 ± 0. 04,significantly higher than that of the control group ((28. 6 ± 3. 7)℃,(26. 4 ± 3. 6)mmHg,0. 53 ± 0. 02;t =2. 354,2. 648,2. 064;P ﹤0. 05). Meanwhile,the recurrence rate was 5. 9% in observation group,significantly lower than that of the control group( 32. 4%;χ2=8. 463,P﹤0. 05). Conclusion The clinical effect of drug-eluting stents implantation in treatment of patients with knee artery lesions is superior to that of balloon expansion.
