Objective To monitor the activities of orbicularis oculi muscle by analyzing the electroneurogram (ENG) of its innervating nerve. Methods The ENG was recorded in vivo by a cuff electrode implanted around a dog’s zygomatic branch of facial nerve. The differences between the ENG during relaxing period of the orbicularis oculi muscle and during the constricting period were analyzed to explore a way to monitor the muscle activities. Results The ENG signals indicating occurrences of eye blinking events were extracted in the study. Time-frequency analysis showed that there was no ENG difference when the orbicularis oculi muscle was in relaxing periods no mater whether it was in the nature eye-opening period or in the interval of eye blinking. The ENG of orbicularis oculi muscle in constricting period was different from the ENG in relaxing period at amplitude and frequency. Conclusion It is feasible to monitor the orbicularis oculi muscle activities by ENG analysis.

Objective To evaluate the effect of exercise on the relationship between body mass index (BMI) and health-related quality of life (HRQOL).Methods A total of 1 114 participants were recruited from the Physical Examination Center of two hospitals.SF-36 was used to measure HRQOL,and the classification of sports level was done according to the subjective evaluation of participants.Results The total score of HRQOL,physical component summary and mental component summary were 76.26± 16.10,75.97 ± 16.67 and 76.55± 18.33 respectively.The results of correlation analysis were as following:the positive correlation between BMI and general health (r=0.109),vitality (r=0.116),social functioning (r=0.092),role emotional (r=0.122),mental health (r =0.145) were significant (P＜ 0.01).The negative correlation between BMI and PF(r=-0.07,P=0.019)was significant.The mediation effects of exercise in was relationship between BMI and general health,vitality,mental health were significant,and the mediating effect were 5.84％,9.14％ and 6.58％.Conclusion This study demonstrates that mediation effects of the exercise are significant in some dimensions of HRQOL,but the direct influence of BMI on the HRQOL plays a leading role.And BMI is a protective factor under certain conditions.

BACKGROUND:Growth-associated protein-43 is the primary substance for constructing plasticity of central nervous system, which is recognized as the first molecular marker for studying growth and repairing injury of nerves. OBJECTIVE: To explore the expression of growth-associated protein-43 in rats with focal cerebral ischemia following bone marrow mesenchymal stem cells (MSCs) transplantation.DEISNG, TIME AND SETTING: A randomized, controlled, animal study was performed at the Laboratory of Department of Neurology, Renmin Hospital of Wuhan University and Doctoral Scientific Research Work Station of C-BONS Pharmacy, Hubei, China, from March 2006 to October 2007.MATERIALS: Sixty adult Sprague Dawley rats, with clean grade, irrespective of genders, weighing (180±20) g, were randomly divided into the model, sham operated, and MSCs transplantation groups, with 20 animals in each group. METHODS: Additional 4 Sprague Dawiey rats, aged 2 months, were selected to isolate and culture MSCs, which was labeled with 5-Bromo-2,-deoxyuridine (BrdU). In the sham operated group, the right internal carotids were deligated after anaesthesia. The remained rats were prepared for models of right middle cerebral artery ischemia. At 24 hours after model preparation, 20 μL culture solution containing 5×105/L MSCs was injected into the left lateral ventricle of rats in the MSCs group, the same volume of phosphate buffer saline was injected in the model group.MAIN OUTCOME MEASURES: The rats were sacrificed prior to and at days 7, 14, and 21 after transplantation. The expression of growth associated protein-43 at the infarcted areas, the survival and migration of transplanted cells were examined by immunohistochemistry, at the same time, neurological deficit scores were recorded.RESULTS: The transplanted MSCs migrated from the left lateral ventricle to the infracted areas. Seven days after transplantation, the expression of BrdU-positive cells was found, reached a peak at day 14, and gradually decreased, until disappeared at 28 days after transplantation. Results of immunohistochemistry image analysis showed that immunological activity of growth associated protein-43 around the infarcted area of the MSCs group was obviously greater than that of the model group at days 7 and 14 after transplantation (P<0.06). There was no neurological deficit in the sham operated group. Moreover, with time prolonged, the neurological deficit scores gradually decreased in the model and MSCs groups, which were significantly lower in the MSCs group compared to the model group at day 14 after transplantation (P<0.05).CONCLUSION: MSCs transplantation up-regulates the expression of growth associated protein-43 around the infarcted area, which is consistent with the recovery of neurological function.

Objective To investigate the relationship between retinal nerve fiber layer thickness and peripheral neuropathy in elderly patients with type 2 diabetes.Methods Clinical data of elderly patients with T2DM in Endocrinology Department in Beijing Hospital were retrospectively collected.Global and sectorial retinal nerve fiber layer(RNFL)thicknesses were measured by using optical coherence tomography(OCT),and never conduction velocity measurements were performed in all patients.Diabetic peripheral neuropathy was diagnosed by the criteria in diabetic neuropathies update(2010,American Diabetes Association).RNFL thickness was compared between diabetic nonperipheral neuropathy group (control group,n =30)and diabetic peripheral neuropathy group (DPN group,n=17)and between different sub-groups.Results The RNFL thicknesses of temporal,nasal,superior and inferior visual fields and the mean RNFL thickness were less in DPN group than in control group,among which there were significant differences in the RNFL thicknesses of superior,inferior visual fields and the mean RNFL thickness [(107.7±27.4)μm vs.(128.1±17.3)μm,(112.9 ±20.8)μm vs.(130.8±21.8)μm,(88.2±15.5)μm vs.(100.5± 11.3)μm,F=7.446,7.468,7.988,respectively,P=0.009,0.009 and 0.007].RNFL thickness was decreased along with the aggravation of DPN from the control group,the subclinical DPN group to the DPN group successively(all P＜ 0.05).Conclusions Retinal nerve fiber layer thickness is associated with diabetic peripheral neuropathy in elderly patients with type 2 diabetes,and the relationship is more significant in patients with serious DPN.

Objective To study the prenatal diagnosis and clinical significance of fetal hyperechogenic kidneys.Methods Thirty one cases with fetal hyperechogenic kidneys were prenatally diagnosed with ultrasound.Autopsy was conducted and histological examination of the kidney was performed when pregnancy was terminated.A close follow-up was given for cases continuing pregnancy.Umbilical cord blood was collected for fetal chromosome analysis after delivery.Results(1)6 fetuses were complicated with other organ abnormalities,3 fetuses had abnormal chromosome,and 2 cases had a family history.(2) 12 cases chose to terminate pregnancy,10 of whom were oligohydromnios.Causes for fetal hyperechogenic kidneys were infantile polycystic kidney disease(IPKD,10 cases),adult polycystic kidney disease (APKD,1 case),polycystic kidney dysplasia(PKD,1 case)after postmortem histological examination. (3)Nineteen cases continued pregnancy,2 neonates with oligohydramnios died during neonatal period,both of them were IPKD;3 cases that were IPKD,IPKD and KPD respectively died 3 months,8 months and 1 year after birth,respectively;one case presented with hypertension symptom 26 months after birth,which was diagnosed as IPKD.The other 13 cases had no clinical manifestation and a close following-up is being undertaken for them at present.Conclusions(1)Fetal hyperechogenic kidneys could be caused by IPKD, APKD,or PKD,and are sometimes a normal variant.(2)Aminotic fluid volume is a key factor for prognosis;a suggestion for termination would be given to cases with fetal hyperechogenic kidneys and oligohydromnios.(3)For cases with fetal hyperechogenic kidneys,a complete and careful ultrasonography should be given to both parents and fetus,and fetal chromosomal analysis is suggested prenatally.

Objective To observe the effects of capsaicin on PGE2 concentration of IL-1β-induced human large cell carcinoma NCI-H460 cells,and further observe its effect on COX-2 and mPGES-1 so as to explore the possible mechanisms against non-small cell lung cancer.Methods NCI-H460 cells were cultured in vitro ;the effect of capsaicin in inhibiting NCI-H460 cells proliferation was observed.The 50% inhibitory concentration (IC50 ) was measured by MTT assay.IL-1βstimulation method was used to construct inflammation model,and the effects of capsaicin on COX-2 activity and PGE2 concentration in NCI-H460 cells were measured by ELISA.The effects of capsaicin on COX-2 and mPGES-1 protein level in NCI-H460 cells were analyzed by Western blot;the effects of capsaicin on COX-2 mRNA and mPGES-1 mRNA expressions in NCI-H460 cells were analyzed by Real-time PCR. Results MTT assay results showed that the growth of NCI-H460 cells treated with capsaicin was significantly inhibited compared with the control group (P <0.05 or P <0.01 ).Capsaicin could significantly decrease COX-2 activity and PGE2 concentration in NCI-H460 cells,and significantly decrease COX-2,mPGES-1 protein levels as well as COX-2,mPGES-1 mRNA expressions in NCI-H460 cells in a dose-dependent manner compared with the control group (P < 0.05 ).Conclusion Capsaicin inhibits the release of PGE2 by downregulating COX-2 and mPGES-1 mRNA expressions in NCI-H460 cells,which may be one mechanism of its effect against non-small cell lung cancer.
