Objective To explore the effects of upper limb robot-assisted therapy on motor recovery in acute stroke patients. Methods From August, 2013 to September, 2014, 46 acute stroke patients at their first-ever stroke were enrolled and randomized into experimental group and control group with 23 cases in each group. Both groups received routine therapy. Additional robot-assisted therapy was provided to the experimental group, and additional repetitive movement training was provided to the control group, 30 minutes a day, 5 days a week for 12 weeks. Fugl-Meyer Assessment-Upper Limb (FM-UL), modified Ashworth Scale (MAS) and modified Barthel index (MBI) were used to assess the motor function of the upper limbs and hands, the muscular tension of elbow, and activities of daily living (ADL) before and after treatment. Results After treatment, the scores of FM-UA, MAS and MBI improved in both groups (t>3.856, Z>1.889, P<0.05), and the scores of FM-UA and MAS were better in the experiment group than in the control group (t=-2.386, Z=-2.625, P<0.05), however, there was no significant difference in the score of MBI between two groups (t=-1.326, P=0.098). Conclusion Upper limb robot-assisted therapy can facilitate the recovery of the motor function of upper limbs in acute stroke patient.

OBJECTIVE: To observe the effect of different frequencies (2 Hz, 100 Hz) of electroacupuncture (EA) on limb locomotion and the expression of inflammatory factors IL-1β, IL-6, TNF-α in sciatic nerve, and nuclear factor kappa B (NF-κB) in lumber(L)4-L5of spinal cord in rats with sciatic nerve injury (SNI), so as to reveal its mechanisms underlying improvement of SNI. METHODS: A total of 48 SD rats (half male and half female) were equally divided into blank control, model, low frequency (2 Hz) EA and high frequency (100 Hz) EA groups. The SNI model was established by clamping the spinal nerve. EA intervention (2 Hz, 100 Hz, 1 mA), starting on the 8th day after modeling, was applied to "Huantiao" (GB30) on the injured side for 15 min, once daily for 14 consecutive days. The sciatic function index (SFI) was calculated to assess the injured hindlimb recovery with reference to BAIN's and colleagues' methods. Histopathological changes of the sciatic nerve were displayed by H.E. staining. The expressions of IL-1β, IL-6 and TNF-α in the sciatic nerve tissue were detected by immunohistochemistry, and the expression of NF-κB in the spinal cord was detected by using Western blot. RESULTS: After modeling, the SFI level on day 8 was significantly decreased in the model group (P<0.01), and no significant differences were found among the model, low frequency EA and high frequency EA groups before the EA intervention (P>0.05). Following the treatment (at the 22nd day), the SFI values of both low frequency EA and high frequency EA groups were significantly increased (P<0.01), suggesting an improvement of the limb motor function, and the SFI of the low frequency EA group was notably higher than that of the high frequency EA group (P<0.01). In comparison with the blank control group, the expression levels of IL-1β, IL-6, TNF-α in the sciatic nerve and NF-κB protein in the spinal cord were significantly up-regulated (P<0.05). Following EA intervention, the increased expression levels of IL-1β, IL-6, TNF-α and NF-κB proteins were significantly down-regulated in both low frequency EA and high frequency EA groups (P<0.05), and the therapeutic effect of low frequency EA was markedly superior to that of high frequency EA in down-regulating the expression levels of IL-1β, IL-6, TNF-α and NF-κB protein (P<0.05). H.E. staining showed increase of Schwann cells in number, cellular swelling, and disintegration of the axons and myelin sheath, and appearance of vacuolar degeneration in the model group, which was relatively milder in both low frequency EA and high frequency EA groups, particularly in the low frequency EA group. CONCLUSION: EA of GB30 at 2 Hz and 100 Hz can promote the recovery of hindlimb motor function in SNI rats, which is probably related to its function in inhibiting the inflammatory response, and facilitating the repair of the damaged sciatic nerve. 2 Hz EA is better than 100 Hz EA in the therapeutic effect.

Objective To investigate in evaluation of various capacity requirement of probationer nurs-ing students by nurses in operation room in order to improve clinical teaching work. Methods A self-de-signed questionnaire was applied, 191 qualified teaching nurses from nine grade three A general hospitals in Beijing were invited to fdl the questionaires. The results underwent subsequent analysis. Results The teach-ers had high expectations for various capacity of the probationer nursing students. Conclusions Clinical teachers should establish feasible teaching scheme according to the existing teaching syllabus in order to in-crease teaching quality, make students gain new insights through reviewing old materials, so that they can mas-ter various technique in operation room in short time.

To explore the influence of matrix materials in complicate ingredients on traditional Chinese medicine and investigate the excipients selection model based on balanced release characteristics of multicomponents, the influence of HPMC (K4M, K15M, K100M) and Carbomer (934P, 971P, 974P) was illustrated by testing in vitro release of ginsenoside-Rg1, ginsenoside-Rb1 and notoginsenoside-R1 in Panax notoginseng saponins (model drug, PNS). According to in vitro release results of PNS matrix tablets in water and artificial intestinal juice, the release curves were analyzed with Peppas equation and simulating factor (f). Significant differences in k value and n value among ginsenoside-Rg1, ginsenoside-Rb1 and notoginsenoside-R1 existed in various formulations. The release behaviors from various excipients could be described with Non-Fickian transport or super Case II transport pattern. The f2 values for ginsenoside-Rg1, ginsenoside-Rb1 and notoginsenoside-R1 in 971P matrix tablet containing 30% Carbomer 971P were 74.91, 53.45, 57.89 in water and 79.35, 55.51, 51.89 in artificial intestinal juice, respectively. The release profiles fit for the regulation of FDA. The result revealed that the balanced release rates of Rg1, Rb1 and R1 in 971P matrix tablet were obtained.

Objective To study the fecel-oral and blood transfusion of TT virus. Methods Paired feces and serum samples from 6 patients with type B and/or C hepatitis were tested for TTV DNA and its titers by PCR with seminested primers.Genotypes were determined after their sequences were compared with the original N22 and TA278 clone.Results TTV DNA was detected in sera from all patients,while it was detected in feces from 3 patients,including 2 with high viral titers in serum.The detection of fecal TTV DNA was dependent on the viral titers in serum.TTV isolates in 3 pairs of feces and serum had identical sequence of 222 base pairs.Their genotypes were 1a,1b and 2,respectively.Conclusion The excretion of TTV into feces indicates that TTV would be transmitted not only parenterally but also nonparenterally by a fecal-oral route.

Objective To explore the role of ureteroacopy for acute upper urinary tract obstructive anuria.Methods Clinical data of 37 cases with acute upper urinary tract obstructive anuria were analyzed.Results Among 37 cases,34 cases were successfully performed ureteroseopy or ureteroseopic lithotripsy with double-J sent incubation (successful rate was 91.9%).Renal function were recovery in 32 cases.4 Cases returned to 180μmol/L,1 case need hemodialysis periodically.Conclusion Ureteroscopy could rapidly remove the obstruction and protect renal function in management of acute upper urinary tract obstruction anuria,which was contributed to the diagnosis.It was safe,effective and the preferred method.

Objective To explore the correlation between cytomegalovirus pneumonia (CMV-IP) and viral load in renal transplant recipients and to find out the threshold value of viral load for predicting CMV-IP. Methods The blood samples of 56 renal transplant recipients were taken weekly for the first 2 months and every 2 weeks for 2-6 months after transplantation.Real-time PCR were used to quantify the plasma CMV DNA.The mean viral loads of CMV-IP group and non-CMV-IP group in each time were compared using Wilcoxon test.Different cut-off values were tested to find the suitable values to predict the CMV-IP. Results Of the 56 recipients,8 (14.3%) developed CMV-IP.The viral loads were near zero in the first 4 weeks in both groups;from week 5 the viral load of CMV-IP group increased gradually and reached the climax at week 8 and then declined,but the load of non-CMV-IP group fluctuated at a low level.During weeks 5-11,the viral loads of CMV-IP group were higher than those of non-VMV-IP group.At 5,7 and 9 weeks,the differences of the viral loads between the 2 groups were significant (P
