Objective To investigate the influence of enteral nutrition (EN) emulsion containing slowrelease starch on blood sugar level in patients with craniocerebral injury. Methods Totally 120 patients with severe craniocerebral injury complicated with hyperglycemia joined this open study and were randomized into control group and study group. Study group was given EN emulsion containing slow-release starch ( Fresubin Diabetes)and control group was given routine EN emulsion ( Fresubin), both for 15 days. Fasting blood glucose (FBG),2-hour postprandial glucose (2hPG), and glycosylated hemoglobin (HbA1c) were examined before EN support and 7 days and 15 days after EN support. Results In the study group, the levels of 2hPG before EN support and on the seventh and fifteenth day after EN support were ( 12.26 ± 2. 36 )mmol/L, (9.76 ± 2.90 ) mmol/L, and (9.78 ± 1.86) mmol/L, respectively. The levels of 2hPG after EN support were both significantly lower than that before EN support (P ＜ 0. 05). However, the levels of FBG and HbA1c in the study group were not significantly different before and after EN support ( P ＞ 0. 05 ). In the control group, the levels of 2hPG on the seventh and fifteenth day after EN support were ( 11.70 ± 2. 80) mmol/L and ( 11.39 ± 2. 44 ) mmol/L, respectively, which were significantly higher than those in study group ( P = 0. 033, P = 0. 020). The levels of FBG and HbA1c werenot significantly different between the study group and the control group ( P ＞ 0. 05 ). Conclusion EN emulsion containing slow-release starch may promote the control of blood sugar in patients with craniocerebral injury complicated with hyperglycemia and improve the level of postprandial blood sugar in those patients.

The relationship between 3 polymorphisms sites [interleulin-4 (IL-4), IL-4 receptor (IL-4R) alpha chain and activation-induced cytidine deaminase (AICDA)] and adult allergic asthma in China was studied. By using case-control method, DNA and clinical data were obtained from allergic asthmatic patients and compared with those in the control subjects. The subjects were genotyped for the IL-4 C-589T promoter polymorphism, the IL-4R alpha chain Q576R and the AICDA C8408T by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. The results showed that the IL-4 C-589T was not associated with adult allergic asthma in China. However, the IL-4R alpha chain 576R/R and AICDA 8408T/T frequency was significantly increased in allergic asthma group as compared with that in the control group [odd ratio (OR) = 3.797 and 9.127, respectively; P < 0.01)] and was correlated with the increased plasma total IgE. These data suggested that the IL-4R alpha chain 576R/R and AICDA 8408T/T genotypes confer genetic susceptibility to adult allergic asthma in China.

AIM: To investigate the linkage between the polymorphism of -109 and Glu237 in the high-affinity IgE receptor?(Fc?RⅠ?) gene and susceptibilty of allergic asthma in adults in a Chinese population. METHODS: Allergic asthma sample in adult and age-and sex-matched control were studied. A-109C/T and a coding variant Glu237Gly in Fc?RⅠ? were detected with polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). RESULTS: (1)The genotype frequencies were 0.415 for -109T/T, 0.491 for-109T/C and 0.094 for -109C/C in allergic asthma in adults. No significant difference in the distribution of-109C/T polymorphism was found between allergic asthma adult subjects and healthy control subjects. However, a homozygosity for the-109T allele was associated with increased total plasma IgE levels in subjects with allergic asthma (F=7.213, P

Objective To evaluate left atrial (LA) function by real-time three-dimensional echocardiography (RT-3D) and speckle tracking imaging (STI) after circumferential ablation of pulmonay vein ostia for atrial fibrillation guided by carto mapping system. Methods Thirty patients who had ablation procedure for paroxysmal atrial fibillation were accepted echocardiography to estimate the LA function at pre-operation,3 days and 3 months of post-operation. The LA maximal, minimal and pre-systolic volume (LAVmax, LAVmin and LAVp), LA passive ejection fraction (LAPEF), LA active ejection fraction (LAAEF) were measured by RT-3DE respectively. The strain rate curve was acquired in each LA segment (anterior, posterior, lateral, inferior and septal) by STI. Systolic strain rate (SRs), early diastolic strain (SRe) and late diastolic strain rate(SRa) of each left atrial segments were measured. Results Comparing with preoperative,3 days post-ablation SRs,SRe and SRa decreased significantly in each wall of LA. After 3 months,SRa and SRe in anterior, inferior and septal were significantly improved, however, SRs showed no significant difference. LAVmax and LAVpre were significantly decreased. LAPEF and LAAEF were significantly improved. Conclusions The patients with circumferential pulmonary vein ablation were in a deterioration after three days. The pump function and conduit functions of left atrial were increased after 3 months.

OBJECTIVE: To provide reference for China to comprehensively promote and perfect the "two-vote system" for drug purchase. METHODS: The effects of "two-vote system" on interested parties, the existing problems of drug purchase and its financial reasons were analyzed; the finance strategies were put forward to deal with the existing problems of drug purchase. RESULTS & CONCLUSIONS: "Two-vote system" has certain impact on drug production enterprises, drug circulation enterprises, public medical institutions and government drug supervision departments. At present, the existing problems of drug purchase mainly include that the mechanism of "drug to support hospital" has promoted the virtual-high price of drugs; drug enterprises pull drug sales by the way of rebate; hidden rules disrupt the circulation of drugs as "be subordinate to" "amateur performance". Financial reasons mainly include that the mode of "drug to support hospital" pursuit the maximization of its own interests unilaterally and ignore the drug cost burden of patients; some enterprises have poor investment, lack of R&D investment, have weak internal financial control measures, lack of social responsibility consciousness, rely on "be subordinate to" "amateur performance" profit, underestimate financial risk, etc. The drug production enterprises should adjust marketing model and reduce cost; drug circulation enterprises should predict positioning scientifically and expand profit space; public medical institutions should reform financial supply and reduce drug cost; government drug supervision departments should reduce the supervision cost and improve the comprehensive efficiency. Only by deepening the reform of the medical and health care system, improving the supporting measures for the "two-vote system" in drug purchase can the problems existing in the circulation of drugs be solved gradually.

Objective To explore the therapeutic effect of immune regulating nutrition on severe acute pancreatitis (SAP). Methods The clinical data of 80 patients with SAP who were admitted to the Union Hospital of Huazhong University of Science and Technology from February 2008 to October 2009 were prospectively analyzed. The 80 patients were equally divided into conventional nutrition (CN) group and immune regulating nutrition (IRN) group. Patients in the CN group received CN support, while patients in the IRN group were supplemented with ω-3 polyunsaturated fatty acid (ω-3 PUFA ) and glutamine at the basis of CN support.APACHE Ⅱ scores were evaluated at day 1, 4, 7, 10, 14 in the course of treatment. The differences in the incidence of pulmonary and abdominal infection, sepsis, and other clinical parameters including operation intervention, mortality, length of ICU and hospital stay between the two groups were compared. All data were analyzed using the t test and chi-square test. Results The APACHE Ⅱ scores of patients in the IRN group were 15.3 ± 1.8 and 9.0 ± 1.8 at day 4 and 7, which were significantly lower than 20.0 ± 2.7 and 13.3 ± 2.4 in the CN group, respectively (t = 3.3, 2. 8, P < 0.05). The APACHE Ⅱ scores of patients in the IRN group at day 10and 14 were also lower than those in the CN group, while there was no significant difference (t =0. 7, 0. 6, P>0.05). The incidences of pulmonary and abdominal infection and surgical intervention rate in the IRN group were 18% (7/40), 13% (5/40) and 5% (2/40), which were significantly lower than 38% (15/40), 33% (13/40)and 20% (8/40) in the CN group, respectively (χ2 =4.0, 4.6, 4.1, P<0.05). The incidence of sepsis in the IRN group was 5% (2/40), which was lower than 8% (3/40) of the CN group, while there was no significant difference between the two groups ( χ2 =0.0, P >0.05 ). The average lengths of ICU and hospital stay in the IRN group were (5.4 ± 1.6 ) days and ( 38.6 ± 9.3 ) days, which were significantly lower than ( 7.8 ± 2.8 ) days and (43.1 ± 1 1.6) days in the CN group, respectively ( t = 2. 7, 3. 7, P < 0.05 ). The morality was 5% (2/40) in the IRN group and 8% (3/40) in the CN group, with no significant difference between the two groups (χ2 =0.0,P >0.05). Conclusion CN support supplemented with ω-3 PUFA and glutamine can adjust the inflammation reaction of SAP and sustain the normal immune function, which is helpful in decreasing the incidence of severe infection.

OBJECTIVETo investigate the link between the polymorphism of -109 and Glu237 in the high-affinity IgE receptor beta (FcepsilonRIbeta) gene and susceptibility to allergic asthma in a Chinese population.

METHODBlood samples from 216 allergic asthma patients and 198 age- and sex-matched controls were studied. A -109C/T and a coding variant Glu237Gly in FcepsilonRIbeta were detected with polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP).

RESULTSThe genotype frequencies were 0.403 for -109T/T, 0.491 for -109T/C and 0.106 for -109C/C in allergic asthma in a Chinese population. No significant difference in the distribution of -109C/T polymorphism was found between allergic asthma subjects and healthy controls, however, homozygosity for the -109T allele was associated with increased total plasma IgE levels in subjects with allergic asthma (F = 4.020, P < 0.05). The allele frequency of Gly237 in the patients and control was 0.236 and 0.136 respectively. There was a significant association between the Gly/Gly genotype and allergic asthma. Among allergic asthma patients Gly237 was significantly associated with high IgE levels.

CONCLUSIONSThese results suggest that the Gly237 variant of the FcepsilonRIbeta gene is involved in the development of allergic asthma. The -109C/T and Glu237Gly polymorphisms are two of the genetic factor identified thus far, which affect total plasma IgE levels of allergic asthma patients in a Chinese population.

Objective To identify the electrophysiological charateristics and cause of ridge gap related reentry after MI ablation in atrial ifbrillation patients. Methods Activation and entrainment mapping was performed in 82 redo cases for OAT recurrence in whom MI was ablated during the index produre. Once ridge gap related reentry was conifrmed, detailed mapping was performed in MI and ridge region. In addition, in 36 cases undergoing MI ablation and fulfilling criterion for bidirectional block, differential pacing was repeated at the ridge to identify a ridge gap. Results Out of 82 redo cases for OAT recurrence in whom MI was ablated during the index produre, 7 (8.5%) was found to be ridge gap related reentry. TCL was (247.9±19.2) ms, and the left atrial endocardial activation time was (145.4±17.7) ms, accounting for (58.5±3.2)%of TCL. However, wide double potential was recorded along the previous ablated MI line where PPI was (34.3±6.6) ms longer than TCL, while PPI was signiifcantly shorter at the ridge[PPI-TCL (11.4±3.9) ms, P<0.001]. Tachycardia was terminated at the ridge in 6 cases and at the corresponding site in coronary sinus in 1 case. No recurrence was found during follow-up for (11.1±4.5) months. In addition, in 36 patients undergoing MI ablation in whom criterion of bi-directional block was fuliflled, conduction gap located at the ridge was found in 5 (13.9%) cases. Conclusions MI ridge gap related reentry is a distinctive OAT, in which the ridge was used as the critical isthmus, whereas the previous ablated MI line is not part of the reentry. MI pseudo-block due to the ridge gap may lead to this type of recurrent tachycardia.

Objective To investigate the effects of miRNAs-107 (miR-107) on pancreatic cancer proliferation,senescence and invasion.Methods MiR-107 expression levels in 3 pancreatic cancer cell lines PANC-1,ASPC-1,BXPC-3 and normal pancreatic HTERT-HPNE cells were studied by quantitative reverse transcription-polymerase chain reaction (qRT-PCR).PANC-1 cells were transfected with 50 nmol/L anti-miR-107 or negative control using Lipofectamine 2000.After transfection,the miR-107 expression was measured by qRT-PCR.Cell proliferation was tested by methylthiazol tetrazolium (MTT) assay.Cell senescence was detected by β-galactosidase staining.The expression levels of PCNA,P16INK4A and MMP2 were measured by qRT-PCR.Results Compared with the HTERT-HPNE cells,the expression level of miR-107 in 3 pancreatic cancer cell lines was significantly increased (P ＜ 0.01).After transfected with 50 nmol/L anti-miR-107,cell proliferation was inhibited,and cell senescence were increased in PANC-1 cells (P ＜ 0.05),and there was no obvious change in cell invasion.Compared with the HTERT-HPNE cells,after transfected with anti-miR-107,the PCNA expression was significantly decreased and P16INK4A was significantly increased,but expression of M MP2 didn't change significantly.Conclusions These results demonstrate that miR-107 promotes the proliferation and escapes cell senescence in PANC-1 cells by targeting PCNA and P16INK4A.But it has no obvious effects on cell invasion.Therefore,it may be a new target for the biologic therapy for pancreatic cancer.
