Enteral resuscitation is a new concept, but the treatment supplied has been already well known. Enteral resuscitation has been used widely for critical patients, which is benefit for their recovery. It is a safe and effective method for critical patients which could result in the amelioration of the hormonal stress response to promote the intestine function and improve outcome, and it is good in cost-effectiveness. Complications are minimal.

Identification and characterization of Niemann-Pick C1 Like 1 (NPC1L1) has established NPC1L1 as an essential protein in the intestinal cholesterol absorption process,and NPC1L1 is the molecular target of ezetimibe, which is a cholesterol absorption inhibitor. The expression of the gene and protein of NPC1L1 may be regulated by some nuclear receptors. Lack of NPC1L1 auses a nearly complete protection from the development of atherosclerosis in apoE-/- mice c, which provides new target for the treatment for atherosclerosis and cardiovascular disease.

Purpose: To observe the long-term and recent clinical effect of needle-warming method plus functional training in the treatment of osteoarthritis of the knee joint. Methods:After 106 cases of the patients were divided into the needle-warming group and comprehensive group by the order of their first visit, the needle-warming group was treated by the needle-wanning method and the comprehensive group was treated by the needle-warming method plus functional training. After ten treatments, the clinical data in the two groups were evaluated upon Lequesne scale before and after the treatments. Three months later, follow-up survey was given to process the statistic management of the reoccurrence rate of the symptoms.Results: In the two groups after the treatment, the symptoms of the knee joint and daily life ability were obviously improved than the respective conditions before the treatment, and the integral decreased (P＜0.05), with no significant difference (P＞0.05) between the two groups. In the follow-up survey, there was a difference (P＜0.05) between the two groups in the positive rate of the recurrent symptoms. Conclusion: Certain therapeutic effect exists in the treatment of osteoarthritis of the knee joint by the needle-warming method. If functional training is combined,the therapeutic effect would be more stable, without easy reoccurrence.

Objective To investigate the effect of nerve growth factor (NGF) and ciliary neurotrofic factor (CNTF) on the regeneration and functional recovery of sciatic nerves following sciatic nerve injuries (SNI). Methods The left sciatic nerves for 6 mm in 120 Wistar ratswere removed and divided randomly into 4 groups. Target muscular injection of NGF at concentration of 100 ng/kg and CNTF at 100 ng/kg was given to Group NGF+CNTF; CNTF at 100 ng/kg to Group CNTF; NGF at 100 ng/kg to Group NGF and equal quantity of normal saline to Group NS. Sciatic nerve functional index (SFI) measurement, morphometric analysis, S-100? and NF200 immunohistochemistry were performed for all the animals after operation. Results SFI, diameter and number of myelinated axons, and axonal quantity of S-100? and NF200 were significantly higher in Group NGF+CNTF than that in other groups. Conclusions Combined application of NGF and CNTF can enhance regeneration and functional recovery of sciatic nerves posterior to SNI.

Objective To investigate the effects of nursing intervention on the rehabilitation of patients with benign paroxysmal positional vertigo (BPPV).Methods 64 BPPV patients were randomly divided into control group and observation group, with 32 cases in each group.The control group received otorhinolaryngology routine nursing, while the observation group was managed with continuously systemic nursing interventions, including manipulative re-duction, psychological nursing intervention, health education, head nursing, follow -up and family nursing interven-tion.The Hamilton Anxiety Scale (HAMA) and Hamilton Depression Rating Scale (HDRS) were applied to evaluate the intervention effects.Results Cure rate of the observation group was significantly higher than that of the control group, and recurrence rate of the observation group was obviously lower than that of the control group(p <0.05).The anxiety and depression assessment of the observation group was significantly lower than that of the control group, with statistical difference (p <0.05).Conclusion Systemic nursing intervention can effectively improve the rehabilita-tion of patients with BPPV, and reduce recurrence rate.

BACKGROUND: Adipose-derived stem cells (ADSCs), a kind of adult stem cells, possess plasticity and can be induced into myocardial cells under certain conditions. Autologous ADSCs transplanted into the infarct area can differentiate into myocardial cells and vascular endothelial cells to construct new vessels and thereby improve cardiac pump function. OBJECTIVE: To study the factors that influence ADSCs differentiation and transplantation and the current clinical and laboratory research progress of ADSCs transplantation for treatment of cardiomyopathy.METHODS: A computer-based retrieval was performed in Medline (between January 1990 and April 2010), PubMed database, the China Biological Medicine Database (CBM) (between January 1990 and April 2010), and China National Knowledge Infrastructure (CNKI) with the keywords adipose-derived stem cells, myocardial cells, cell differentiation, cell transplantation, cardiomyopathy treatment.RESULTS AND CONCLUSION: A total of 30 articles, consisting of 6 reviews and 24 randomized controlled trials, were obtained. At present, there have been uniform methods of ADSCs isolation and culture, and ADSCs can be effectively proliferated in vitro, but there have been no direct methods to identify these stem cells. ADSCs differentiation can be induced both in vitro and in vivo, besides, with a characteristic of early differentiation. ADSCs transplantation is a more conductive therapy for myocardial disease compared with bone marrow stem cells (BMSCs) transplantation. Different ADSCs transplantation methods should be carried out in different types of cardiomyopathy. Stem cell labeling technique can help to dynamically monitor implanted in vivo. Transplantion of autologous ADSCs is a new way to treating cardiomyopathy. However, for successes in clinical practice, the method to inhibit tumor cells-promoting characteristics is needed to ensure long-term safety of the patients receiving ADSCs transplantation.

Flocculent gene FLO1 and its truncated form FLO1c with complete deletion of repeat unit C were expressed in a non-flocculent industrial strain Saccharomyces cerevisiae CE6 to generate recombinant flocculent strains 6-AF1 and 6-AF1c respectively. Both strains of 6-AF1 and 6-AF1c displayed strong flocculation and better cell growth than the control strain CE6-V carrying the empty vector under acetic acid stress. Moreover, the flocculent strains converted glucose to ethanol at much higher rates than the control strain CE6-V under acetic acid stress. In the presence of 0.6% (V/V) acetic acid, the average ethanol production rates of 6-AF1 and 6-AF1c were 1.56 and 1.62 times of that of strain CE6-V, while the ethanol production rates of 6-AF1 and 6-AF1c were 1.21 and 1.78 times of that of strain CE6-V under 1.0% acetic acid stress. Results in this study indicate that acetic acid tolerance and fermentation performance of industrial S. cerevisiae under acetic acid stress can be improved largely by flocculation endowed by expression of flocculent genes, especially FLO1c.

Objective To discuss the influence hand hygiene intervention on general ICU acquired methicillin-resistant staphylococcus aureus (MRSA) infection and its improvement. Methods Hand Hygiene Cognition Questionnaire that passed the reliability and validity test was used to compare the change of cognition on hand hygiene of medical staff. According to the results of the questionnaire, the intervention was carried out by continuous intensive training. The compliance with hand hygiene of medical staff was observed by monitoring equipment in the ward. Implementation status and effect of hand hygiene of medical staff on duty were examined randomly each month. At the same time MRSA infection rate of patients in comprehensive ICU was monitored in the same period. The relationship between hand hygiene compliance and MRSA infection rate was analyzed. Results The score of medical staff of cognition of hand hygiene was (41.70±3.67) points before the intervention, while the score was (44.10±3.55) points after the intervention. The difference had statistical significance (t=24.37, P<0.01). The correct rate of hand washing, positive rate of bacterial culture in hand, hand hygiene compliance and infection rate of MRSA of patients in comprehensive ICU were 68.75%, 14.58%, 66.90%, 12.90% respectively before the intervention. The correct rate of hand washing, positive rate of bacterial culture in hand, hand hygiene compliance and infection rate of MRSA of patients in comprehensive ICU were 88.54%, 3.12%, 74.14%, 3.10% respectively after the intervention. The difference had statistical significance (χ2=7.809-24.520, P<0.01). Conclusions Questionnaires with high credibility reviews could better identify issues in hand hygiene compliance, and sustained, reinforcing intervention measures could improve the compliance of hand hygiene; Good hand hygiene practice of medical and nursing staff contributes to controlling MRSA infection rates in general ICU.
