At present,nutrition therapy plays a very important role in critically ill children,which can impact on the development and outcome of the disease by the process of metabolism and immunity.Immune-modulating nutrients,such as glutamine,which is a current hot topic,but now there is a little research in it in critically ill children,and this paper summarizes the approach,the dose and the efficacy of glutamine in critically ill children,aiming to offer reference in clinics.

This study is based on the application of the medical simulator and the multimedia technology to the medical English teaching for overseas students during their clinical practice in surgical department.It shows that this teaching model is effective by delivering a good studying surroundings and various language carriers.

Objective To investigate the optimal time points for transplantation with in vitro cultured dopaminergic neurons as a potential treatment of Parkinson’s disease. Methods After the ventral mesencephalic precursors from E11 rat embryos were expanded for 7 days in vitro, they were harvested respectively from day 0 to day 7 in the period of induced differentiation. Then the cells were seeded again and cultured for another 7 days. The final survival of dopaminergic neurons determined the optimal time points for moving cells in vitro and, possibly, for transplantation in vivo. Result The survival rate of dopaminergic neurons moved on day 0 and day 1 in the period of induced differentiation was significantly higher than that at other time points. Conclusion The optimal time points for transplantation are found possibly to be day 0 and day 1 in the period of differentiation after the expansion of ventral mesencephalic precursors from E11 rat embryos.

Objective To study the levels of interleukin(IL)-2 ,interferon-γ(IFN-γ) and IL-10 in peripheral blood and the effec-tive concentration of lactate dehydrogenase(LDH) in serum of patients with acute leukemia .Methods 65 patients with acute leuke-mia were divided into non-remission group(n=35) and remission group(n=30) .50 healthy volunteers were used as control group . The levels of IL-2 ,IFN-γ ,IL-10 in peripheral blood were measured by enzyme linked immunosorbent assay(ELISA) .The effective concentration of LDH was measured by automatic biochemical analyzer .Results The levels of IL-2 ,IFN-γin non-remission group were significantly decreased compared with control group and remission group(P<0 .05) ,but the level of IL-10 in non-remission group was significantly increased compared with control group and remission group(P<0 .05) .The effective concentration of LDH in non-remission group was significantly higher than that in control group or remission group(P<0 .05) .Conclusion The levels of IL-2 ,IFN-γand IL-10 in peripheral blood and the effective concentration of LDH in serum of patients with acute leukemia have changed .Clinical detection of IL-2 ,IFN-γ,IL-10 and LDH may contribute to the early diagnosis of patients with acute leukemia .

To provide suggestions for perfecting essential drug centralized bidding and purchasing system. Methods:Using literature method to analyze comparatively essential drug bidding purchasing implement plans of 30 provinces in China. Results:Bidding mode in most provinces was double envelope system. Most evaluation methods did not distinguish the quality level, while there were great differences among provincial evaluation standard and scores of economic, technical and business bidding. Conclusion: To explore scientific and reasonable evaluation standard, it needs to establish an authoritative evaluation system for reference, choose the objective index as far as possible and properly increase the amount of bidding manufacturer.

0.05).Conclusion The 4-combine radical treatment to Hp infection can reduce the concentration of ammonia in gastric juice and blood ammonia obviously in patients with liver cirrhosis,whose Child-Pugh grade are A and B,and the treatment is effective in preventing heptic encephalopathy.

Objective To explore changes of procedural memory in patients with primary insomnia(PI) and its characteristics.Methods Thirty-six PI patients and 36 controls were enrolled.The procedural memory was respectively detected with category exemplar generation and motor sequence tasks,and the declarative memory was assessed by free recall task.Results Compared with the controls,PI patients showed few correct numbers in the category exemplar generation (7.0 (6.0,8.8) vs 9.0 (9.0,11.0),Z=5.537,P＜0.01) and motor sequence task (8.0±3.3 vs 11.5 (8.6,13.8),Z=4.152,P＜ 0.01)and the phases of immediate recall (3.0 (2.3,4.0) vs 6.0 (5.0,7.0),Z =6.479,P ＜ 0.01),delayed recall (9.0 ± 2.2 vs 11.0 (10.0,12.0),Z =4.747,P ＜ 0.01) and delayed recognition (15.0 (13.0,15.0) vs 15.0 (15.0,15.0),Z=4.637,P＜0.01) of the free recall task.Furthermore,the early morning awakening group had significantly lower correct numbers in the motor sequence task,the delayed recall and recognition phases of the free recall task than the difficulty initiating and maintaining sleep groups.Conclusion The procedural and declarative memories are impaired in the PI patients,especially the early morning awakening insomniacs.

Objective To compare the clinical effects of proximal femoral nail antirotation (PFNA) and dynamic hip screw (DHS) in the treatment of intertrochanteric fractures in elderly patients.And provide a reasonable basis for clinical treatment of elderly patients with intertrochanteric fractures.Methods The clinical and follow-up records of 58 elderly patients with intertrochanteric fractures treated by PFNA and DHS were retrospectively reviewed.For times of operation,blood loss in operation,length of incision,incidents of complication and Harris's hip functional standard score were compared and analyzed.Results PFNA group operation time[(59.61 ± 8.27)min],amount of bleeding[(234.51 ± 38.80)ml] were both better than the DHS group of[(83.54 ± 11.12)min and (446.57 ±54.01) ml] respectively.There were significant differences (t =9.80,18.10,all P ＜ 0.05).The satisfactory rate was 92.8％ in PFNA group,higher than the DHS group's 83.3 ％ (x2 =6.18,P ＜ 0.05).There was significant difference between two groups in the incident of complication,DHS group was higher.Conclusion PFNA internal fixation with a minimally invasive,fixed solid and recovery fast,is the better internal fixation in the treatment of elderly intertrochanteric fracture patients.
