Objective:To explore the effect of rehabilitation nursing on muscle spasm of patients in persistent vegetative state (PVS). Methods:To adopt the rehabilitation nursing methods on 98 PVS patients, including the arrangement of comfortable body position, passive motion, massage, etc.and then to evaluate the patients’ spasm situation with the universally emendatory MAS (motor assessment scale) methods. Results:Under the rehabilitation nursing and correlative curing, the patients’ limbs muscular tension had been improved evidently(x2=17.04, x2=14.04, P<0.01). Conclusion:Good limb position and physical movement rehabilitation nursing training do not need special equipments or techniques. If only the nursing personnel could master the training methods and skills, they could help the PVS patients to control and to decrease the muscle spasm and then to help them ease the pain.

Objective To study the effect of cold prolonged storage of rat livers with self-designed HYS solution on hepatic biochemical functions.Methods The preservation effect of HYD solution with that of UW solution and Lactate Ringer's solution(LR)was compared by using isolated perfused rat liver model.Results All the indices of hepatic biochemical functions in HYD group were better than in LR group for 12 h storage.The contents of ATP,TAN and AEC in HYD group were significantly higher than in Uw group for 36 h storage(P＜0.05).pH in HYD group was markedly higher than in UW group for 30 or 36 h storage(P＜0.05).The hydrolytic activities of H+-ATP ase in hepatic mitochondria and bile production were mildly higher in HYD group than in UW group(P＞0.05).No significant difference in AST,ALT and LDH in the effluent were found between HYD group and UW group(P＞0.05).Conclusions The effect of 12 h storage of rat livers with HYD solution might be better than with LR solution.The effect of HYD solution is similar to that of UW solution within 36 h storage.However.HYD solution is slightly superior to UW solution in some aspects.such aS improvement of energy metabolism during cold storage and reperfusion,prevention of intracellular acidosis.bile production and perfusion of liver in situ.

Objective To explore whether the dopamine D1 and D2 receptors were involved in pathogenic mechanism of Parkinsonian mice induced by paraquat. Methods The models of Parkinson's mice were induced by oral paraquat. The levels of dopamine D1 and D2 receptor proteins and the expression of receptor mRNAs in striatum were examined by immunohistochemistry and in situ hybridization, respectively. Results Mice treated by oral paraquat (10mg?day -1 ?kg -1 ) for four months displayed marked hypoactive behavior. The levels of dopamine D1 and D2 receptor proteins in the striatum were significantly decreased by 28% and 29%, respectively (P

Objective:To analyze the effects of super early rehabilitation nursing on poststroke depression, to sum up the nursing experience.Methods: The control group included 78 cases of stroke patients, the observation group included 77 cases, the observation group was given super early rehabilitation nursing after stroke seventh days, thirtieth days, ninetieth days, with Hamilton Anxiety Scale(HAMA) and Depression Scale(HAMD)assessment of patients with anxiety or depression levels, and statistical correlation index.Results: Stroke after 7 days, 30 days and 90 days in PSD group, severe occurrence of PSD was higher than that in the observation group, stroke after 30 days, 90 days in the control group are more likely to commit suicide than the observation group, stroke after 90 days of control group, PSD turnover rate is higher than that of the control group, the difference was statistically significant specific(x2=6.62,x2=13.74;P<0.05).Conclusion: PSD can occur in each time period after stroke, most self outcome; super early rehabilitation nursing is helpful to reduce the incidence of PSD risk.

Methods:To choose 48 patients, were randomly divided into control group, 24 cases in each group to observe, are basic rehabilitation training, observation group joint mirror therapy, using FMA, ARAT, BMI, respectively, evaluation of patients with general motor function, upper limb motor function, daily life ability, numerical measurement of radial carpal extensor emg. Results:After the treatment, the control group, the observation group the FMA level, ARAT level, MBI level, EMG level was higher than that before treatment, the observation group than that in the control group, the observation group FMA, ARAT, MBI, the difference of EMG signals is higher than that of control group, with significant difference(t=14.14,t=4.55,t=5.84, t=9.14;P<0.05).Conclusion: mirror therapy combined with rehabilitation training is really helpful to upper extremity motor functional recovery of stroke patients with hemiplegia, is of positive significance to improve the living ability of the patients.

BACKGROUND:Numerous diseases like cardiac hypertrophy and intervertebral disc degeneration are known to be implicated in the changes of mechanical stress acting on surrounding tissues or cells, and autophagy contributes to the pathogenesis of these diseases. OBJECTIVE:To review the effects of mechanical factors on autophagy in different tissues and the underlying molecular mechanisms, thereby providing references for the research of autophagy and the prevention and treatment of related diseases. METHODS:A search of Web of Science and PubMed databases was performed for the literatures addressing the effects of mechanical factors on autophagy using the English keywords ofautophagy, mechanicaland the articles were summarized systematically. Finally, 52 literatures were enrolled according to the inclusion and exclusion criteria. RESULTS AND CONCLUSION:Mechanical factors make great effects on autophagy of various cells, such as myocardial cells, endothelial cells, chondrocytes and skeletal muscle cells. Autophagy is a self-protective reaction, and the mechanical stress of physiological conditions induces autophagy to maintain cellhomeostasis, normal function and survival. The mechanism of autophagy induced by mechanical stress may involve PI3K-AKT-mTOR, oxygen free radical, AKT-FoxO and other pathways, and the definite mechanism needs to be further studied.

Objective To evaluate the feasibility of methylene blue as a method in lymphatic mapping and the effect factors of SLNB identification rate. Methods The results of SLNB in 276 patients with clinical stage T-T2N0M0 breast eaneer were analyzed to evaluate the effect factors of identification rate and false-neg-ative rate of SLNB. Results The identification of SLN was carried out using methylene blne . When the mapping time of SLN and lymphatic were controlled in 20～30 minutes, the SLN could be visualized easily. SLN was successfully identified in 246 of 276 patients (89.1%) ,423 SLNs were retrieved(1～4). The SLN accurately predicted the status of the axilla in 226 of 246 patients (77.3%) yielding a FNR(false negative rate)of 8.1% (20/246) ,false positive rate of0, and an accuracy of 91.9% (226/241). For the identified rate of SLN, the clinical stage of T2N0M0 disease was higher than the clinical stage of T1N0M0 disease (P=0.046,P<0.05), Upper outer quadrant and lower outer quadrant were higher than other evidently (P<0.0010). SLNs were easily retrieved in those cases aged above 50 years than below 50 years (P<0.001).In the view of false-negative rate of SLNB, the FNR rate in patients of 50 years old was less than older ones (P=0.037, P<0.05). No significant correlation was found between the stage of TMN, the expression of ER and PR, histologic status and FNR. Conclusion When SLNB was performed using methylene blue, we found age, clinical stage of TMN, the location of tumor had relationship with the identified rate of SLN. Ag-ing and location of tumor may adversely affect FNR of SLNB.

The capillary density of control was (125?23)/mm 2, and in VEGF group was (298?27)/mm 2, P

NAD(P)(H)-dependent oxidoreductase catalyzes the reduction of ketones or aldehydes to prepare a wide variety of valuable chiral alcohols or amines. However, expensive cofactors are absolutely required for the biocatalytic processes with oxidoreductases, which severely hinder their industrial applications. Consequently, the issue on reducing cofactor costs has become one of the major focuses in the field of biocatalysis. With the substantial development in recent years, a number of strategies have been proposed and implemented to solve the cofactor issues in the oxidoreductase catalyzed biocatalysis, including the establishment of cofactor regeneration system, the improvement of endogenous cofactor availability via metabolic engineering and the development of biomimetic agents to replace cofactors. In this review, recent trends and advances on these strategies are presented, and respective advantages and shortcomings are also discussed with a number of examples.
