Objective To study how polyclonal antibodies against ciliary neurotrophic factor (CNTF) reduce botulinum toxin-in- duced axonal sprouting and affect paralytic muscle.Design Experimental study.Participants 20 New Zealand rabbits.Methods In 10 rabbits randomly selected,left superior rectus were as control (Group 1),right superior rectus were injected with botulinum toxin A (BTXA) 2.5U (Group 3).At 14th day,bilateral superior recti were taken out under general anaesthesia.In the other 10 rabbits,left su- perior recti were injected equivalent physical saline (NS) as control (Group 2);right superior recti were injected with BTXA 2.5U,after 4 days,injected with 50?l polyclonal antibodies against CNTF at same site (Group 4).And at 14th day,bilateral superior recti were taken out for electron microscopy,dyed with acetylcholinesterase,argentums (Ag) to show nerve axonal sprout,and accounted and mea- sured with Leica microsystems.Main Outcome Measures The mean number of sprouts and the mean total length of sprouts,and the uhrastructure change of muscle by electron microscopy.Results In Group 1,the mean number of sprouts and the mean total length of sprouts were 5.75% and 10.53?m respectively;Group 2 were 6.11% and 11.16?m;Group 3 were 84.04% and 170.71?m;and Group 4 were 54.77% and 68.12?m.The differences were statistically significant (all P=0.000).Electron microscopy showed that after admin- istration BTXA alone (Group 3),muscle atrophied obviously,nerve myelin sheath increased,while the structure of nerve and muscle re- main invariable.The Group 4 showed that local myofilament disrupted and dissolved,degenerative myocytes necrotized and disintegrat- ed into fragments,which led to partial unreversible destroy.Conclusion Polyclonal anti-CNTF can reduce BTXA-induced axonal sprout- ing,lead to partial unreversible destroy of muscle,which may prolong the time of paralytic muscle resuming.It suggests that polyclonal anti-CNTF could prolong the duration of muscle paralyses induced by botulinum toxin.

OBJECTIVETo observe the effect of Bushen Huatan Recipe (BHR) on the Akt signal pathway in polycystic ovarian syndrome (PCOS) model rats with insulin resistance (IR).

METHODSFifty Wistar female PCOS rats were randomly and equally divided into 5 groups, i.e., the control group, the model group, the low dose BHR group (5.406 g/kg), the medium dose BHR group (10.812 g/kg), and the high dose BHR group (21.624 g/kg), 10 in each group. Levels of fasting blood glucose (FBG) and insulin were detected to calculate homeostasis model assessment of insulin resistance (HOMA-IR). The expression of insulin receptor substrate 1 (IRS-1), glycogen synthetase kinase-3beta (GSK-3beta), glucose transporter 4 (GLUT-4), and peroxisome proliferator activated receptor (PPAR-gamma) mRNA were detected by RT-PCR. The expression of insulin signal transduction molecular kinase B (Akt) was detected by Western blot.

RESULTSCompared with the control group, HOMA-IR and the mRNA expression of PPAR-gamma mRNA significantly increased, the mRNA expression of GSK-3beta, GLUT-4, and IRS-1, protein expression of Akt and p-Akt significantly decreased in the model group (P < 0.05). Compared with the model group, HOMA-IR significantly decreased, the mRNA expression of GSK-3beta, GLUT-4, IRS-1, and Akt protein significantly increased in the high dose BHR group (P < 0.05, P < 0.01). The mRNA expression of p-Akt protein increased more obviously (P < 0.05, P < 0.01). mRNA expression of GSK- 3beta and GLUT-4 significantly increased (P < 0.05), while the mRNA expression of PPAR-gamma significantly decreased in the low and middle BHR groups (P < 0.05). The expression of p-Akt significantly increased in the low dose BHR group (P < 0.05).

CONCLUSIONSIR and abnormal insulin signal pathway existed in PCOS model rats. BHR could improve IR of PCOS rats, which was correlated with regulating protein expression of insulin signal transduction molecules.

BACKGROUND:Classic media and fetal bovine serum are commonly used in the culture of umbilical cord mesenchymal stem cells, but the potential risk of serum culture limits its clinical application. OBJECTIVE:To use human platelet lysate alternative to fetal bovine serum for large-scale production of mesenchymal stem cells for therapeutic applications. METHODS:Human platelet lysate was prepared by repeated freezing and thawing, centrifugation, filtration, and concentration. Human umbilical cord mesenchymal stem cells were cultured in Iscove’s Modified Dulbecco’s Medium containing 5%concentrated platelet lysate (experimental group) or 10%fetal bovine serum (control group). After separation and enzymatic digestion, human umbilical cord mesenchymal stem cells were subcultured at a concentration of 3 000/cm2 up to the fifth generation. Then, cellmorphology and diameter, immune phenotype, osteogenic and adipogenic differentiation, and cloning efficiency were detected and compared between two groups. RESULTS AND CONCLUSION:Human umbilical cord mesenchymal stem cells cultivated in human platelet lysate-supplemented media showed a smal er size and more elongated morphology than those in fetal bovine serum-supplemented media. Colony forming unit-fibroblast analyses further showed no significant differences in colony efficiency. Human umbilical cord mesenchymal stem cells cultivated in human platelet lysate-supplemented media showed an increase of proliferation capacity;whereas, similar immunophenotypes remained in the two groups. In vitro assays revealed intact differentiation potential. Moreover, human umbilical cord mesenchymal stem cells cultivated in human platelet lysate-supplemented media showed a significantly higher capacity to differentiate towards osteocytes, indicating human platelet lysate is an alternative to fetal bovine serum for low-density production of mesenchymal stem cells for therapeutic applications.

Objective: To develop the Chinese version of the Neuropsychiatric Inventory Questionnaire (NPI-Q) and evaluate its reliability and validity. Methods: Three investigators assessed 10 dementia cases together with the NPI-Q to evaluate the inter-rater reliability. Eighty-six dementia cases and 30 healthy controls were assessed with the Behavioral Pathology in Alzheimer's Disease (BEHAVE-AD), the Brief Psychiatric Rating Scale (BPRS) and NPI-Q to evaluate the criterion validity. A subgroup of 30 dementia cases was tested with the NPI-Q again 24 h later to evaluate the test-retest reliability. Results: (1) Internal consistency. Cronbach's a coefficient of the severity subscale was 0.589, mean inter-item correlation coefficient of the severity subscale was 0.107. Cronbach's α coeffi-cient of the distress subscale was 0.612, and the mean inter-item correlation coefficient of the distress subscale was 0.114. (2) Inter-rater reliability. Intraclass correlation coefficient (ICC) of the severity subscale was 0.97, and ICC of the distress subscale was 0.94. (3) Test-retest reliability. The test-retest correlation coefficient of the severi-ty subscale was 0.89, and the test-retest correlation coefficient of the distress subscale was 0.86. (4) Criterion va-lidity. The severity subscale total score was correlated significantly with BEHAVE-AD (r=0.70, P <0.001) and BPRS(r=0.40, P<0.001) total score; the distress subscale total score was correlated significantly with the global ratings in part 2 of BEHAVE-AD (r=0.76, P<0.001) . (5) The severity subscale total score in demen-tia group was significantly higher than that in control group (median: 10 vs.1.5, P <0.001). The distress sub-scale total score in dementia group was significantly higher than that in control group (median: 10 vs 0; P< 0.001) . (6) Exploratory factor analysis identified 4 common factors, including psychosis, abnormal behavior,discontrol and affective symptoms, which explained 58.3% of total variance. All of the items loaded were between 0.596 and 0.803 on their conrresponding factor. Conclusion: The reliability and validity of the Chinese version of NPI-Q meet the psychometrics properties, and deserves to conduct further study in larger samples.

Objective To explore the effect of nursing clinical pathway in percutaneous coronary intervention(PCI)for patients with acute myocardial infarction(AMI).Methods Sixty AMI patients were randomly divided into nursing clinical pathway(NCP) group and control group equally by their registration sequence.Patients in the control group received routine nursing care,while patients in NCP group received nursing according to the nursing clinical pathway.Results Compared with the conventional group, the time of preoperative preparation,bed rest and hospitalization was obviously shortened.The incidence of complications and hospital costs were both declined,and meanwhile the quality of care and patient satisfaction improved significantly(P<0.05). Conclusions The application of nursing clinical pathway in patients with AMI can be timely and effective in the treatment of PCI, lower the mortality and complications and moreover improve nurses' working enthusiasm.

Both single and long-term aerobic exercise may play a role for insulin resistance (IR), however, there is no agreement for in-terval exercise. Simple resistance training is controversial, and the significance of resistance-aerobic exercise for IR is also mixed.
