Objective To investigate the anti-oxidation effects of compound Chinese medicine of Yiqiling,on the spon- taneously hypertensive rats(SHR) and to explore the new target for improving the prognosis of hypertension.Method SHR were randomly divided into 2 groups:Yiqiling group and the control group.The serum content of malondiadehyde (MDA) and superoxide dismutase(SOD),and the urine content of 8-iso prostaglandin F2?(8-isoPGF2?) in two groups were measured.Examination of the gene expression profile was analyzed by using cDNA microarray.Three of the anti-oxidation genes were selected to undergo RT-PCR and quantitative real-time PCR.Results The 8-isoPGF2?urine level and MDA serum level were lower,and SOD serum level was higher in Yiqiling group than those in the control group,the differences of the above indexes had statistical significance.In Yiqiling group the expression of 354 genes was up-regulated and that of 121 genes was down-regulated in comparison with the control group.The results of the Hsphl,Hspca and Pam genes detected by RT-PCR and quantitative real-time PCR were consistent with those detected by the microarray examination.Conclusion Yiqiling has anti-oxidation effects and improvement on the prognosis of SHR,and its possible mechanism is related with the regulation of Hsphl,Hspca and Pam genes expression.

Objective To investigate the role of compound traditional Chinese medicine Yiqilin in the regulation of immune-related genes expression in spontaneously hypertensive rats(SHR).Methods Ten SHR were randomly divided into test group(fed with Yiqilin and ordinary food at the ratio of 1:9 for 6 months,n=5)and control group(fed with ordinary food for 6 months,n=5).Total RNA was extracted from myocardial tissues of SHR after 6 months,and gene chip hybridization technique was employed to analyse the expression of immune-regulated genes of myocardial tissues in two groups.The genes with differentiation expression were screened,and were verified by Real-time PCR.Results The expression of 32 immune-related genes were up-regulated in the test group,including interleukin(IL)6 receptor,IL-6 signal transduction factor,chemotatic factor,antigen presenting molecule,antibody receptor,heat shock protein(Hsp), etc.No immune-related gene was down-regulated in test group.The results of 2 immune-related genes(Hsp 105 and Hsp 90)detected by Real-time PCR were consistent with those by gene chip hybridization.Conclusion Part of the immune-related genes in myocardial tissues in SHR may be up-regulated by Yiqiling,which indicates that Yiqiling may play a role in the regulation of expression of immune-related genes in SHR.

AIM: To compare the efficiency and safety of torsional phacoemulsification with or without intelligent phacoemulsification ( IP ) software in hard nucleus cataract extraction.
METHODS: Ninety two eyes with Ⅳ - Ⅴ grades cataracts were enrolled in this randomized prospective study. Operated eyes were divided into two groups -those operated without IP software ( non- IP group, n =43) and those operated using IP software (IP group, n =49 ). The two groups were compared in terms of ultrasound time (UST) and cumulative dissipated energy (CDE). Post- operative outcome measures included the corneal edema and best-corrected visual acuity (BCVA) at 1,7d and 3mo postoperatively, corneal endothelial cell density and percentage of hexagonal cell at 7d and 3mo postoperatively.
RESULTS: UST was measured as 52. 51±9. 64s in non-IP Group and 48. 79±7. 13s in IP Group (P = 0. 030). CDE was 15. 78±3. 73% in non-IP Group and 14. 29±2. 77% in IP Group ( P = 0. 026). At the first postoperative day, the rate of BCVA>0. 1 in non-IP Group was 56%, and the rate in IP Group was 79% (P= 0. 066). Corneal edema in non-IP Group was 2. 98±0. 77 scores, and in IP Group it was 2. 61±0. 64 scores (P = 0. 021). At the postoperative 7 and 30d, the BCVA and corneal edema were no differences between two groups. At the postoperative 7d, corneal endothelial cell density in non- IP Group were 2497. 95 ±211. 48 / mm2 , less than 2586. 26±154. 71 / mm 2 in IP Group (P= 0. 029);percentage of hexagonal cell in IP group was 48. 33±8. 69%,higher than 44. 19±9. 48% of non-IP group(P= 0. 030).CONCLUSION: In hard nucleus cataract extraction, the IP software can combine the advantages of the two kinds of ultrasonic modes, which is more effective with lower ultrasound energy and less injury for the corneal endothclium, and is helpful for the recovery of vision at early stage after surgeries.

Objective To investigate the pathogenic types and clinical features of children with lobar pneumonia. Methods Eighty children with lobar pneumonia diagnosed from April 2013 to May 2015 were enrolled. Bronchoalveolar lavage lfuid (BALF) of patients were collected. FQ-PCR was used to detect and analyze pathogens in BALF. Results In 80 cases, 59 cases were Mycoplasma pneumoniae, and 2 cases were Chlamydia pneumoniae, 12 cases were Streptococcus pneumoniae, 1 case was Klebsiella pneumoniae, 8 cases were adenovirus, 1 case was respiratory syncytial virus, 14 cases were of mixed infection. The prevalence of MP lobar pneumonia in children of 7-14 years old age group were higher than that of other age groups. Conclusions The pathogen of children with lobar pneumonia varied from Mycoplasma pneumoniae, Chlamydia pneumoniae, bacteria, virus and so on, and Mycoplasma pneumoniae was the common pathogen in lobar pneumonia.

Objective To summarize the clinical nursing experience for patients with malignant obstructive jaundice after receiving percutaneous biliary radiofrequency ablation (RFA) and stent implantation. Methods The postoperative nursing experience in 9 patients with malignant obstructive jaundice who received percutaneous biliary RFA together with stent implantation were retrospectively analyzed. The postoperative complications and the nursing intervention measures were analyzed and evaluated. Results Biliary RFA and subsequent stent implantation were successfully carried out in all 9 patients. After the procedure, biliary fistula occurred in one patient, biliary hemorrhage in 2 patients and biliary infection in 2 patients. The patient, who developed biliary fistula, died one week later, and the clinical conditions in the remaining 4 patients were improved after symptomatic treatment. During the follow-up period of one month, the patients were in good condition. Conclusion The main purpose of postoperative nursing for patients after receiving percutaneous biliary RFA is to prevent the occurrence of bile duct perforation, hemorrhage, infection, etc. It is very important to keep the patients under close observation and comprehensive nursing so as to make an early detection and timely treatment of such complications, thus to reduce the incidence of complications causing serious consequences as well as to promote an early recovery.
