OBJECTIVE:To study the characteristics of adverse drug reactions(ADR) induced by gatifloxacin.METHODS:A total of 866 ADR cases induced by gatifloxacin collected in Zhejiang ADR Monitoring Center between Oct.30,2003 and Oct.30,2006 were analyzed with Excel.RESULTS:The common ADR induced by gatifloxacin were lesions of skin and appendages,gastro-intestinal system,systemic and nervous system.Most of the cases were slight in symptoms,but gatifloxacin could also induce severe ADR such as dysglycemia etc that resulting in potential risks to vital human organs.CONCLUSION:ADR monitoring should be emphasized when using gatifloxacin so as to decrease or avoid the occurrence of ADR.

Objective To explore the basic medical mechanism of XinBao pill on electrophysiological characteristics of hyperpolarization-activated cyclic nucleotide-gated channel 4 (HCN4), and illustrate the mechanism of its therapeutical effect on bradycardia.Methods Human HCN4 mRNA was injected into the Xenopus laevis oocytes, after incubated for 2 ~3 days, channel current properties of HCN4 perfused with 40 mg/L XinBao Pill were observed by double electrode voltage clamp technique.Results At-90mV test potential, compared with control group (no XinBao pill), HCN4 channel peak current and tail current in 40 mg/L XinBao pill group had obvious changes, and V1/2 from ( -103.61 ±3.57)mV to ( -106.42 ±5.33)mV in XinBao pill group, from( -81.11 ±4.26)mV to( -86.36 ±7.44)mV in control group.The values of k from (15.15 ±2.23)mV to (17.33 ±3.58) mV in XinBao pill group, from(11.78 ±0.85)mV to(12.39 ±1.51)mV in control group(n=10).At test potential -90 mV, 40 mg/L XinBao pill perfusion fluid decreased the instantaneous current of(0.15 ±0.24)%, the EC50 was (30.8 ±4.8)mg/L (n=8).At test potential-140 mV~-100 mV level, 40 mg/L XinBao pill group increased the channel activation time constant compared with control group[(226.73 ±31.36)ms vs(143.67 ± 21.44)ms;-140 mV,n=10,P<0.05].40 mg/L XinBao pill group increased the channel deactivation time constant compared with control group [(1293.53 ±95.02)ms vs (647.12 ±61.35)ms;-140 mV,n=10,P<0.05].Conclusion The XinBao pill enhances the instantaneous current of HCN4 in a concentration-dependent manner, and extents channel activation and deactivation processes.

ObjectiveTo investigate the psychological loneliness status of the Zhuang empty nester in rural area,and analyze the influencing factors.Methods 320 cases were randomly extracted in certain groups in xiangxian town,Shanglin County of Guangxi Zhuang Autonomous Region,including 160 empty nester( Group A),80 living with families elderly people (Group B ),80 state-fending elderly people (Group C ).The questionnaire and University of California Los Angeles Loneliness Scale(UCLA) were applied for this investigation.ResultsThe top three single-positive rates of the UCLA of the Group A was their hobby different from others (69.54％),lack of sense of intimacy(65.56％ ) and lack of trust(61.59％ ).The UCLA score was significantly different in the Group A(52.44 ±7.29),the Group B(32.16 ±9.01),the Group C(39.65 ± 8.11 ) (F=178.97,P ＜ 0.05).Multiple regression analysis showed a negative correlation between the UCLA score and the number of great-grandson living with the elderly,a positive correlation between the UCLA score and the interval of the children to visit the elderly.ConclusionThe Zhuang empty nester in rural area was very lonely.It is helpful to alleviate the loneliness of the Zhuang empty nester in rural area through establishing a comprehensive pension system,the duties of children to their parents and the family harmony.

Objective To compare the serum protein profiles between people with successful aged 80 years and over in Bama versus Nanning,to identify the possible causes of the long life expectancy in Bama.Methods We evaluated the serum protein profiles using surface-enhanced laser desorption ionization time-of-flight mass spectrometry (SELDI-TOF-MS) with 4 different chromatographic surfaces,including the weak cation exchange (CM10),immobilized metal affinity capture (IMAC) 30-Cu,strong anion exchange (Q10) and hydrophobic surface (H50) protein chip arrays in people with successful aged 80 years and over living in Bama versus in Nanning city.SELDI-TOF-MS had a molecular mass detection range of 2000-50,000 D,with a first signal-to noise (S/N) ratio of 5,frequency of peak cluster of over 15 ％,and second S/N ratio of 2 and peak fluctuation of 0.3％ (m/z).Results The total numbers of serum protein (peptide) peaks for people with successful aging in Bama and Nanning were 71 on CM10,46 on IMAC30-Cu,81 on Q10,and 52 on H50.Among subjects from Bama as compared with Nanning (P＜0.05; mean ＞SD for each protein peak),there were 8 differently expressed protein peaks on CM10,of which 2 were upregulated and 6 downregulated; 7 on IMAC-Cu,of which 2 were upregulated and 6 downregulated; 5 on Q10,all of which were upregulated; and 6 on H50,of which 3 were upregulated and 3 downregulated.Conclusions There are marked differences in the serum protein profiles between people with successful aging living in Bama versus in Nanning.Most of the proteins are downregulated among people aged over 80 years in Bama.

Objective: To establish the quality standard for compound Heishen pills. Methods: Scrophulariae Radix, Radix et Rhizoma and Belamcancae Rhizoma were identified by TLC. HPLC was used to determine the content of harpagoside and cinnamic acid in Scrophulariae Radix on a Welchrom-C18 column using methanol-acetonitrile-1% ethylic acid (8∶21∶71) as the mobile phase. The flow rate was 1. 0 ml·min-1 . The column temperature was at 30℃ and the detection wavelength was set at 278 nm. Results:The TLC method had good specificity without interference from negative control. The linear range of harpagoside was 1. 32-65. 80μg·ml-1 with the average recovery of 98. 06%(RSD=2. 16%),and that of cinnamic acid was 0. 38-19. 20 μg·ml-1 with the average recovery of 98. 78%(RSD=1. 34%). RSDs of precision, stability and reproductibility tests were all below 2%. Conclusion: The established method is accurate, feasible and reproducible. It can be used in the quality control of compound Heishen pills.

Objective To evaluate the clinical efficacy of transjugular intrahepatic portosystemic shunt(TIPS)combined with stomach and esophageal variceal embolization(SEVE)for gastric variceal haem-orrhage,and the efficacy with or without a gastrorenal shunt. Methods A total of 52 patients with gastric variceal bleeding history and portal hypertension treated with TIPS combined with SEVE were included from October 2013 to March 2015.Patients were divided into two groups according to preoperateive CT angiogra-phy,27 cases with gastric variceal haemorrhage associated with a gastrorenal shunt in group A,and 25 gastric varices bleeding cases without gastrorenal shunt in group B. During the follow-up,the incidence of the total rates of rebleeding,TIPS primary patency and hepatic encephalopathy,and the survival rates were compared between group A and group B. Results In all patients,the average portal vein pressure decreased from 36. 50±7. 00 cmH2 O(1 cmH2 O= 0. 098 kPa)before operation to 28. 15±6. 27 cmH2 O after TIPS combined with SEVE,with significant difference(t= 10. 357,P= 0. 001). Fifty two patients were followed up for 1 to 18 months(1-18 months in group A;1-15 months in group B).The total rates of rebleeding,TIPS primary patency,hepatic encephalopathy and survival were 11. 54%(6/ 52),86. 54%(45/ 52),11. 54%(6/ 52) and 92. 31%(48/ 52),respectively. There were no significant differences between the two groups in the total rates of rebleeding[11. 11%(3/ 27)VS 12. 00%(3/ 25),P = 1. 000],TIPS primary patency[88. 89%(24/ 27)VS 84. 00%(21/ 25),P= 1. 000],hepatic encephalopathy[14. 81%(4/ 27)VS 8. 00%(2/ 25), P= 0. 738]or total survival rate[92. 59%(25/ 27)VS 92. 00%(23/ 25),P = 1. 000]after TIPS combined with SEVE. Conclusion TIPS combined with SEVE is effective for gastric varices,and equally effective in the treatment of both gastric variceal haemorrhage associated with a gastrorenal shunt and gastric varices bleeding without gastrorenal shunt.
