Chinese Journal of Sports Medicine 2003;0(05):-
Objective To explore a new method for evaluating muscle fatigue by analyzing the surface electromyographic(SEMG) signal characteristics and to search for the practical use of SEMG.Methods Four healthy young females performed continuous isometric contractions of vastus medialis at 65? knee extension with 60% MVC for 3 minutes. SEMG signals were recorded from bilateral vastus medialis. The data were analyzed through curve fitting and nonlinear regression.Results All the estimative curves for SEMG parameter in relation to the testing phase are of cubic with the equations of Y=b_0+b_1x+b_2x2+b_3x3. The b1 and b3 in the formula are negative and b2 is positive for MF,MPF,ZCR, whereas the b1 and b3 are positive and b2 is negative for AEMG.Conclusion The cubic curve during muscle fatigue suggests that three main factors may involve in muscle fatigue. The factors were discussed briefly and need to be confirmed further.

China Pharmacy 2016;27(20):2861-2863
OBJECTIVE:To investigate the role of clinical pharmacists in the therapy for sever acute pancreatitis induced by hy-perlipidemia(HL-SAP)patient. METHODS:Clinical pharmacists participated in the therapy for a pregnant patient with HL-SAP af-ter cesarean section,assisted physicians to optimize therapy plan through analyzing the disease condition according clinical guide and relevant literatures. Clinical pharmacists suggested to decrease atorvastatin 20 mg,qd to 10 mg,qd in order to avoid the risk of rhabdomyolysis and liver injury. When patient’s hemogram kept stable and infection had been controlled,clinical pharmacists suggested antibiotics de-escalation treatment:Levofloxacin injection 0.5 g,ivgtt,qd+Metronidazole injection 0.5 g,ivgtt,q12 h in-stead of meropenem. RESULTS:Physicians adopted the suggestions of clinical pharmacists. The patient was recovered and transfer to gastroenterology department 15 d later. CONCLUSIONS:Clinical pharmacists provide pharmaceutical care for HL-SAP patient after cesarean section,and assist physicians to formulate therapy plan so as to reduce the incidence of ADR effectively and guaran-tee the safe and effective use of drugs.

Objective To investigate the different effect of positive and negative emotion induced by film clips on explicit and implicit memory,and whether there is mood congruency effect. Methods Thirty participants who were randomly assigned to three experimental groups were investigated. They were exposed in different film clips and then worked on memory task. After each emotional condition,the 5-point Self Assessment Scale was registered , Buchner's processing dissociation corrected model was employed to separate explicit and implicit memory. Results (1) The emotion arousal level of different films is significantly different, the scores of negative film and positive film were more than that of neutral film( (3.24 ± 1.02),(2.85 ± 1.35),(1.12 ± 1.42) , P<0.01) ; the scores of emotional valence of positive,negative and neutral priming condition were (4. 10 ±0. 20), (3. 60 ± 0.22) and (3.20 ±0. 97), and there was a significant difference between emotion priming conditions (F(2,27) = 46.81, P< 0. 01). (2) There was a significant difference among different emotion priming conditions in R (F(2,87) = 30.129, P<0.05) .and there was no significant difference among different emotion priming conditions in A. (3) In R,there was a main effect in emotional words(F(2,81) = 10.516, P<0.05) ,the R scores of neutral words were significantly higher than those of negative words(P<0.01) ,there was a main effect in emotion priming conditions(F (2,81) =10.516, P<0.05) ,the R scores of positive emotion priming group and neutral emotion priming group were significantly higher than those of negative emotion priming group (P<0.05). There was an interaction of emotional words and emotion priming conditions(F(4,81) = 10.640, P < 0.01). Under positive emotion priming condition, the R scores of positive and neutral words were significantly higher than those of negative words (P<0.05);under negative emotion priming condition, the R scores of negative words were significantly higher than those of positive words (P <0.05); under neutral emotion priming condition, the R scores of positive and neutral words were significantly higher than those of negative words (P<0.05). (4) In A, the main effect of emotion priming conditions and emotional words and interaction effect between them were not significant(P>0.05). Conclusions Explicit memory showed mood congruency memory effect,but implicit memory,neither the positive emotion priming group nor the negative emotion priming group exhibited mood congruency memory effect.

BACKGROUND:Stem cell transplantation can, in theory, rebuild the immune system and regulate immunologic function. In addition, the transplanted stem cells may differentiate into tissues or cells we want. Therefore, this intervention may restore gastrointestinal inflammatory lesion and exert therapeutic effect on inflammatory bowel diseases (IBD). OBJECTIVE:To review the application of different kinds of stem cells in IBD treatment. METHODS:A computer-based search of CNKI, PubMed and FMJS was performed for articles concerning stem cel transplantation and IBD published after January 2002. The key words were stem cells, inflammatory bowel diseases, Crohn's diseases, ulcerative colitis, cell therapy in Chinese and English respectively. At last, 49 articles were included in result analysis. RESULTS AND CONCLUSION: Embryonic stem cells and adult stem cells both have certain therapeutic benefits in IBD. But which kind of stem cell is the safest and most efficacious cannot be confirmed, and at the same time the most effective and the optimal dose and way of transplantation of such cells are still unclear. All in all, there is still a lot of work to do to remove the obstacles.

Objective To investigate the placenta perfusion in pre-eclampsia by three-dimensional power Doppler ultrasound and analysing the clinical outcome. Method 80 cases of normal and pre-eclampsia pregnant women from July 2007 to May 2008 in Beijing Obstetrics and Gynecology Hospital were studied. The control group of 36 cases, pre-eclampsia were divided into three groups: a total of 44 cases, mild pre-eclampsia group (9 cases), severe pre-eclampsia group (26 cases) and chronic hypertension with pre-eclampsia group (9 cases). The placental vascular index (VI), flow index (FI), blood vessels and blood flow index (VFI) by three-dimensional Doppler histogram and the umbilical blood flow systolic to diastolic (S/D) by color Doppler flow imaging were calculated and the gestational age after delivery, birth weight, placental weight after birth were recorded respectively. Results (1)VI、 FI、 VFI and umbilical blood flow S/D value :6.3±2.9, 38.6±4.4, 2.7±1.3, 2.5±0.6 in normal group ;5.7±3.8, 36.3±7.2, 2.4±2.0, 2.4±0.3 in mild pre-eclampsia group;3.0±2.4, 31.7±5.0, 1.1±1.0, 2.9±1.3 in severe pre-eclampsia group ;2.2±1.6, 26.1±4.4, 0.8±0.6, 3.1±1.6 in chronic hypertension with pre-eclampsia group. Placenta of normal group and mild preeclampsia group VI, FI, VFI were no significant difference (P>0.05), placental VI, FI, VFI of severe preeclampsia group and chronic hypertension with severe pre-eclampsia group were significantly lower than the normal group (P<0.01) and than mild pre-eclampsia group (P<0.05). The umbilical blood flows were not obvious difference among four groups (P>0.05) ; (2) Gestationul age after birth, birth weight, low newborn weight rate and placental weight:(38.7±1.5 ) weeks, (3280±520) g, 3%, (568±141) g in normal group; (37.9±1.0) weeks, (2971±265) g, 0,(576±98) g in mild pre-eclampsia group; (33.2±2.6) weeks, (1820±737) g,58%, (458±154) g in severe pre-eclampsia group; (32.6±2.6) weeks, (1497±533) g, 7/9, (396±141) g in chronic hypertension with pre-eclampsia group. The normal group and mild pre-eclampsia group in gestationul age after birth, birth weight, low newborn weight rate and placental weight were not significant difference (P>0.05); severe pre-eelampsia and chronic hypertension with severe pre-eclampsia group in them were significantly lower than the normal group (P<0.01) and than mild pre-eclampsia group (P<0.05).Conclusions (1) Placental blood flow perfusion of the severe pre-eclampsia and pre-eclampsia with chronic hypertension of pregnancy decreased resulting in clinically lower placental weight, birth weight and gestational age at delivery, but there were no obvious differences in umbilical blood flow S/D values. (2) The investigation was helpful to clinical diagnosis in the placenta perfusion of pre-eclampsia by three-dimensional power Doppler ultrasound.
