AIM　To observe the protective effects of TGP on local cerebral ischemia. METHODS　The local cerebral ischemia in rat was made by middle cerebral artery occlusion(MCAO). The infraction weight was determined by NBT stain. SOD, MDA and apoptosis were determined with different method respectively. RESULTS　TGP 20 mg*kg-1 ip markedly improved the abnormal nervous symptoms, increased the SOD activity and reduced contentes of MDA in MCAO rat. TGP 20 mg*kg-1 ip significantly decreased the numbers of apoptotic cells in ischemic cortex. CONCLUSION　TGP has protective effects against cerebral infarction, and its mechanism may be related to anti-apoptosis and free radical.

The β-cyclodextrin cross-linked polymer(β-CDCP) was used as adsorbent to pre-concentrate/separate the trace p-nitrophenol and then the determination was carried by UV-Vis spectrophotometry. Under alkaline condition,the adsorption/elution behavior of p-nitrophenol was studied. In 0. 02 mol/L NaOH solution and at room temperature for 30 min,the resin could separate and pre-concentrate the p-nitrophenol effectively. Methanol solution(1:1,V/V) was used as eluent and the β-CDCP could be used repeatedly. The linear range and detection limit was 0.5 -90.0 mg/L and 3. 10 μg/L,respectively. The proposed method has been used to determine the p-nitrophenol in synthesized sample with satisfactory results.

Objective To compare the therapeutic effect of endoscopic variceal ligation (EVL) and β-blockers plus isosorbide mononitrate (ISMN) in prevention of esophageal varieeal re-bleeding. Methods The randomized clinical trials (RCTs) on EVL and β-blockers plus ISMN for the prevention of esophageal varieeal re-bleeding were searched, and only the results from those with Jadad score higher than 3 were eval-uated with RevMan 4. 2 software for odds ratio (OR) with 95% confidence intervals (95%C1). Analysis of sensitivity was performed on the quality of the data and publication bias was investigated with funnel plots. Results Four trials matched the criteria were recruited including 504 cases with a follow-up from 8 to 25 months. There was no significant difference in rates of re-bleeding (OR =0. 93, 95% CI =0. 41 ～ 2. 11 ; P = 0. 87), re-bleeding due to esophageal varices (OR = 0. 68, 95% CI = 0. 19 ～ 2. 37 ; P = 0. 54), therapy-re-lated adverse effects (OR = 1.12, 95% CI =0. 75 ～ 1.67, P = 0. 57), severe adverse events (OR = 0. 89, 95% CI =0. 47 ～ 1.67, P = 0. 71), bleeding-related mortality (OR = 2. 11, 95% CI = 0. 88 ～ 5.08, P = 0. 10), or overall mortality (OR = 1.46, 95% CI = 0. 95 ～ 2. 24, P = 0. 09) between EVL and β-blockers plus ISMN groups. However, a trend towards lower bleeding-related mortality and overall mortality favored drug therapy. There was no heterogeneity found in the outcomes apart from re-bleeding (P = 0. 003) or re-bleeding from esophageal varices (P <0. 0001). The result of sensitivity analysis remained statistically sta-ble. Symmetric funnel plots showed there was no evidence of publication bias. Conclusion EVL and β-blockers plus ISMN show an equivalent efficacy and safety for the prevention of esophageal variceal re-bleed-ing. There is a trend towards lower bleeding-related mortality and overall mortality in drug therapy. But EVL is free from drug-related side effects, and its adverse events are similar to those of drug therapy. Thus, either of the two approaches can be used as the first choice for prophylaxis of re-bleeding of esophageal varices.

Objective To explore the application of bilevel non-invasive mechanical ventilation in the treatment of chronic obstructive pulmonary disease(COPD) with respiratory failure.Methods 126 COPD patients with type Ⅱ respiratory failure were selected and divided into control group and research group,63 cases in each group.The control group received regular treatment,and the research group received bilevel non-invasive mechanical ventilation on the basis of regular treatment.,The results of blood gas analysis,respiratory frequency(RR),heart rate(HR) and expiratory flow(PEF) were observed and compared between the two groups.Results The indicators of pH,PaCO2,PaO2 in the research group after treatment were (7.41±0.08),(51.26±12.13)mmHg,(77.28±15.34)mmHg,which in the control group were (7.26±0.07),(67.21±13.05)mmHg,(69.26±14.31)mmHg,compared with before treatment,pH and PaO2 of the two groups were increased,PaCO2 was decreased after treatment,and the three indicators of the research group were changed significantly better than those of the control group,the differences were statistically significant(t=11.2,7.11,3.03,all P<0.01).After treatment,HR and PR of the two groups were decreased,PEF was increased.The three indicators of the research group were also changed significantly better than those of the control group,the differences were statistically significant(t=3.13,8.58,5.45,all P<0.01).Conclusion Bilevel non-invasive mechanical ventilation in the treatment of COPD with respiratory failure has remarkable clinical effects,can significantly improve the patients' blood gas analysis index,HR,RR and PEF,and it is worthy of clinical application.

Newborn due to low birth weight caused by preterm or fetal growth restriction will have an adverse effect on kidney development. In adulthood,the long-term adverse effects of low birth weight are associ-ated with a variety of kidney disease. Current studies suggest that low birth weight may participate in a variety of kidney disease development and progression by affecting the nephron number,the function of the vascular struc-ture and the endocrine level. This paper mainly reviews the relationship between low birth weight and kidney dis-ease.

Objective:To invetigate the use of targeted anticancer drugs in our hospital during 2011-2013 to provide reference for the clinical rational drug use. Methods:The utilization of anti-tumor molecular targeted drugs in our hospital during 2011-2013 was retrospectively analyzed in respect of consumption sum, DDDs and DDC. Results:The proportion of consmption sum of anti-tumor mo-lecular targeted drugs in the total consumption sum was increased year by year, and that in 2012 and 2013 was over 60%. Protease ki-nase inhibitors accounted for 41. 29%-73. 41% in the consumption sum of anti-tumor molecular targeted drugs; monoclonal antibody accounted for 19. 40%-30. 88%; the other drugs accounted for 7. 19%-27. 83%. The consumption sum and the number of receiving medication patients of rituxan and cetuximab were not synchronized well, and the patients were born the higher cost.

Objective To investigate the relationship among serum levels of suppressors of cytokine signaling-3(SOCS-3),insulin-like growth factor binding protein-1(IGFBP-1) and hyperglycemia in critically ill children. Methods The 64 critically ill children who suffered from sepsis,after surgical repair of congenital heart dis-ease by extracorporeal circulation, and after surgery of severe traumatic from January 2009 to January 2012 in Depart-ment of Pediatric Intensive Care Unit( PICU) of Guangzhou Women and Children′s Medical Center were selected as the research object. According to the blood glucose levels on admission, the 64 children were divided into the normal glu-cose group and the hyperglycemia group. The 15 cases of healthy children in the same period in Guangzhou Women and Children′s Medical Center were selected as the healthy control group. The levels of blood glucose,insulin,SOCS-3,IG-FBP-1 and insulin resistance index( HOMA-IR) were measured and compared among groups when they were on ad-mission. Results (1) The blood glucose of the hyperglycemia group was significantly higher than those in the normal glucose group and the healthy control group[(9. 83±2. 48) mmol/L vs (4. 82±0. 76) mmol/L,(4. 49±0. 81) mmol/L] (P<0. 05). (2) Both of the insulin and HOMA-IR in critically ill children with hyperglycemia were significantly higher than those in the other 2 groups[9. 68(5. 85,17. 35) mU/L vs 4. 08(2. 00,7. 41) mU/L,2. 83(2. 00,10. 10) mU/L;4. 30(2. 70,7. 66) vs 0. 87(0. 39,1. 94),0. 52(0. 38,2. 56)](P<0. 05). (3) The serum SOCS-3,IGFBP-1 levels among the hyperglycemia group,the normal glucose group and the healthy control group were not of significant difference (P>0. 05). (4) The blood glucose was positively correlated with the insulin and HOMA-IR(r=0. 455,0. 773,P<0. 05),but there was no significant correlation among the blood glucose,insulin,HOMA-IR,SOCS-3 and IGFBP-1(P>0. 05). Con-clusions In the critically ill children,hyperglycemia was related to the insulin resistance which can not be evaluated through changes in serum levels of SOCS-3 and IGFBP-1. In addition,it cannot be excluded that the critically ill chil-dren may have insulin resistance and pancreaticβ-cell dysfunction simultaneously.
