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.

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.

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 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.

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 observe the effect of Sishen Pill on ICAM-1 mRNA and protein expression of colonic mucosa in rats with ulcerative colitis (UC), and identify its mechanism. Methods Taolly 40 SPF Wistar rats were randomly divided into blank group, model group, Pill group and SASP group. Except the blank group, UC model was prepared with TNBS/ethanol enema. Pill group was given Sishen Pill 5 g/kg, and SASP group was given SASP 0.3 g/kg by gavage, blank group and model group was given the same volume physiological saline for three weeks. Morphological injury of colonic mucosa was observed and scored. ICAM-1 gene and protein expression were detected by RT-PCR and immunohistochemical method. Results Inflammation and ulceration were found on the colonic mucous membrane of rats in the model group. The expression of ICAM-1 gene and protein of colonic tissues of rats in the model group increased compared with that of the blank group (P<0.01). Compared with the model group, the expression of ICAM-1 in Pill group decreased (P<0.05, P<0.01). Conclusion Sishen Pill can decrease the expression of ICAM-1 mRNA and ICAM-1 protein, inhibit the infiltration of inflammation cells, prevent and reduce colon tissue damage, and play a vital role in the treatment of UC.

Objective To observe the influence of Sishen Pill on the NF-κB p65 mRNA and protein expressions of colonic mucosa in rats with experimental ulcerative colitis (UC), and identify its underlying mechanism of action. Methods The experimental rats were divided into blank group, model group, Sishen Pill group and SASP group. The models were prepared by TNBS/ethanol enema. Sishen Pill group was intragastrically administrated by Sishen Pill extract 5 g/kg, SASP group by SASP 0.3 g/kg, and blank group and model group by equal volume of normal saline. The morphological injury of colonic mucosa was observed and scored with the naked eyes, and NF-κB p65 gene and protein expression were detected by RT-PCR and immunohistochemical method. Results Inflammation and ulceration on the colonic mucous membrane were found in the model group by naked eyes, and had significant difference with the blank group (P<0.05). The relative expression amount of NF-κB p65 gene and protein of colonic tissues were increased in the model group compared with the blank group (P<0.01). Compared with the model group, the relative expression amount of NF-κB p65 gene and protein in Sishen Pill group were decreased (P<0.05, P<0.01). Conclusion Sishen Pill has effect for treating UC, which is probably related to the activation of NF-κB signal transduction pathway.

Objective To investigate molecular types and drug resistance of methicillin-resistant Staphylococcus aureus (MRSA) in Zhejiang province.Methods One hundred and fourty-seven clinical MRSA isolates were collected from 11 grade A tertiary hospitals during January 2009 and December 2010 in Zhejiang province.Minimal inhibitory concentrations (MICs) of 13 antimicrobial agents were determined by agar dilution.Multilocus sequence typing (MLST),staphylococcal cassette chromosome mec (SCCmec) typing and spa typing were used to examine the homology of the strains,and drug resistance patterns were compared among different molecular types.Simpson index was used to determine the discriminatory power of three typing methods.Results Fourteen STs were identified in 147 MRSA isolates,of which ST239 (75 isolates),ST5 (24 isolates) and ST59 (23 isolates) were the most prevalent clones.Four SCCmec types (types Ⅱ to Ⅴ) were identified in 141 isolates,and 6 isolates were not typed.SCCmec type Ⅲ was the predominant type (76 isolates),which was followed by type Ⅳ (32 isolates),type Ⅱ (24 isolates) and type Ⅴ (9 isolates).All MRSA isolates yielded 23 spa types,in which t030 (57 strains),t437 (17 strains),t002 (15 strains) and t037 (12 strains) were the predominant spa types.MRSA strains were sensitive to linezolid,teicoplanin,vancomycin and norvancomycin,but were highly resistant to other antibacterial agents,especially in strains carrying clone ST239 or of SCCmec type Ⅲ.The discriminatory power of MLST,SCCmec and spa typing were 0.6885,0.6577 and 0.8165,respectively.Conclusion The predominant clone of MRSA strains in Zhejiang province was ST239-SCCmec Ⅲ-t030-MRSA,and these strains are highly resistant to most antibacterial agents,so that the surveillance of MRSA in hospital should be strengthened.
