ObjectiveTo investigate the relationship between the oxidative injury induced by low glucose and mitochondrial membrane potential in HUVEC-12 cells. Methods Human umbilicalvein endothelial cells HUVEC-12 were cultured in low concentration glucose for 4 h.Cell viability of HUVEC-12 cell was assessed with MTT assay.Dihydroethidium (DHE) was used as a reactive oxygen species (ROS)capture, which was detected the mean fluorescence intensity of samples and Rhodamine 123 as a fluorescence detector was to measure the level of mitochondrial membrane potential (MMP) in cells.Results Comparing to HUVEC-12 cells viability in 5.5 mmol/L glucose group (96.80 ±3.20)％, cells exposed to 2.8 mmol/L glucose group (66.40 ± 1.60) ％ and 0 mmol/L glucose group (58.93 ± 1.67) ％ were decreased by 32％ and 40％ respectively (P ＜ 0.01).ROS level of 5.5 mmoL/L glucose group, 2.8 mmol/L glucose group and 0 mmol/L glucose group were 0.59 ± 0.02, 0.74 ± 0.04 and 0.88 ± 0.05,respectivdy, increased by 25％ in cells exposed to 2.8 mmol/L glucose and by 48％ in cells without glucose exposure comparing to 5.5 mmol/L glucose group (P ＜0.01) ; MMP levels of 5.5 mmol/L glucose group,2.8 mmoL/L glucose group and 0 mmoL/L glucose group were 148.83 ± 3.51, 271.07 ± 19.54 and357.74 ±51.32 respectively, increased to 1.8 times in cells exposed to 2.8 mmol/L glucose and to 2.4times in cells without glucose exposure comparing to 5.5 mmoL/L glucose group (P ＜ 0.01).Conclusion Low glucose leads to injury in HUVEC-12 cells, which is probably induced by the oxidative stress via the increasing MMP.

Objective To evaluate the neuroprotective effect and safety of neonatal hypoxic-ischemic encephalopathy(HIE)treated with recombinant human erythropoietin(rhEPO).Methods Fifty-three neonates with HIE were randomly divided into rhEPO treated group(n=29) with the dosage of 300 U/(kg?time),three times a week for 2 weeks and control group(n=24)without rhEPO.All supportive measures were same between 2 groups.Neurological scoring was evaluated at d3,d5 and d7 Neonatal behavioral neurological assessment(NBNA) was evaluated at d7,d14 and d28.The neurodevelopment quote was evaluated at age of 3 and 6 months.Blood pressure,liver and renal function,blood electrolytes and blood hemoglobin,platelet and reticular red blood cell count were monitored before and after treatment in all infants.Results The neurological scoring between two groups had no difference at d3.The significant difference was found at d7(P0.05).Conclusions Teraphy with rhEPO on neonatal HIE infants can promote neurological recovery,and there is no serious side effect with rhEPO treatment.

OBJECTIVETo observe the therapeutic effect of massage with manipulation of supplementing marrow and kneading tendon (SMKT) on spastic cerebral palsy (CP).

METHODSA total of 60 children with CP were randomly assigned to the treatment group and the control group equally. All were treated with rehabilitation training, but massage with SMKT was carried out additionally for those in the treatment group, five times every week and 3 months as a therapeutic course. Clinical efficacy was assessed adopting the gross motor function measurement (GMFM-66) and the revised Ashworth scale (MAS) before and after treatment.

RESULTSAll children showed significant improvements in GMFM-66 after treatment. Compared with baseline, the improvement was statistically significant (P <0.01). Significant difference was also found between the 2 groups in MAS and in GMFM scores after treatment (P <0.05).

CONCLUSIONMassage with SMKT manipulation shows a better effect than rehabilitation training therapy alone in treating spastic CP.

Objective To assess the value of detecting sympathetic skin response (SSR) in the diagnosis of autonomic dysfunction in patients with Parkinson disease (PD). Methods SSR measurement was performed in 47 PD patients and 20 healthy control subjects and the results were compared. The SSR was also comparatively analyzed between patients with and those without autonomic dysfimction. Results Compared with the healthy controls, the PD patients showed significantly lowered mean amplitude (2.56±1.47 vs 1.87±0.26, P<0.05) and prolonged latency (1.42±0.29 vs 1.55± 0.18, P<0.05) of the SSR in the upper limbs, with also lowered mean amplitude (0.76±0.39 vs 0.49±0.21, P<0.05) and prolonged latency (2.04±0.27 vs 2.13±0.16, P<0.05) in the lower limbs. Compared with the PD patients without autonomic dysfunction, those having autonomic dysfunction showed significantly lowered mean amplitude (1.89±0.33 vs 1.75±0.21, P<0.05) and prolonged latency (1.53±0.15 vs 1.56±0.17, P<0.05) of SSR in the upper limbs and lowered mean amplitude (0.51±0.17 vs 0.46±0.20,P<0.05) and prolonged latency (2.08±0.24 vs 2.17±0.18, P<0.05) in the lower limbs. Conclusion The results of SSR measurements are consistent with the clinical manifestations of the PD patients. SSR can be of value in the diagnosis of autonomic nerve dysfunction in PD.

Objective To explore the ameliorative effects of standardized tertiary rehabilitation(STR)on the quality of life(QOL)of stroke patients with hemiplegia.Methods Eighty-two stroke patients were randomly divided into two groups:a rehabilitation group(R group)and a control group.All patients were given routine inter- nal medicine treatment,but STR was also administered to the R group.The QOL of all of the patients was assessed with the brief scale of quality of life(QOL-BREF)at the beginning,and at the end of the Ist month,3rd month and 6th month after stroke.Results There were two deaths in the control group,but no deaths in the R group.At ever- y stage,the R group returned better scores for physiological health,psychological state,social and environment rela- tionships,the subjective QOL and health items,and in comprehensive self-evaluation.QOL scores,except for social relationships,were consistently,significantly higher in the R group.The R group's QOL scores improved obviously in the first 3 months after stroke,and then more slowly in the next 3 months.Conclusions STR markedly improved the QOL of stroke patients.Their QOL scores improved obviously soon after stroke,but slowly later on.

Objective To examine the reliability,validity and sensitivity of FCA for stroke patients. Methods A total of 82 patients with stroke were divided into a treatment group and a control group randomly.The patients in the control group were given routine internal medicine treatment,while those in the treatment group were given standardized rehabilitation therapy in addition to the routine internal medicine treatment.All patients were as- sessed with FCA and Modified Barthel Index(MBI),at admission and the end of the 1st month,3rd and 6th month,respectively after the onset of stroke.The internal consistency,split-half reliability,content validity,crite- ria validity and sensitivity of FCA were tested.Repeat measure ANOVA and correlation analysis were used in the statistical analysis.Results There existed a good internal consistency(Cronbach?=0.901～0.973)as well as a good split-half reliability(R=0.949～0.981)of FCA.There was a medium to strong correlation among the 18 items scores of the FCA and FCA scores(P

OBJECTIVETo compare the regulatory effects of electro-acupuncture (EA) at acupoints Zusanli (ST36) and Hegu (LI4) on the visceral hyper-sensitivity in the rat model of irritable bowel syndrome (IBS), and to explore the acting targets and specialty of acupoints.

METHODSExcept 8 rats of the normal control group, the rest 32 rats were prepared to set up the IBS models. IBS animal model was prepared by enema with acetic acid. Model rats were divided into three groups. Except for rats in the model group for control, those in the other two groups were treated 20 min by EA on ST36 (EA-ST36) and LI4 (EA-LI4) respectively for 2 weeks to observe the effect on behavior response of viscera sensitivity. The changes of neuropeptide (NPY), the somatostatin (SS) levels in blood and tissues of brain and intestine were monitored as well.

RESULTSThe volume thresholds for abdomen uplifting and back hunching were obviously increased after EA-ST36 (P<0.05), but showed insignificant change after EA-LI4. NPY contents lowered and SS contents increased in model rats; both EA-ST36 and EA-LI4 could raise the level of thalamic NPY (P<0.01 and P<0.05, respectively), but showed insignificant effects on NPY in colonic tissue. As for SS content, its colonic level could be reduced by EA-S36 and EA-LI4 (P<0.01 and P<0.05, respectively), however, its blood level was affected only by EA-ST36 (P<0.05).

CONCLUSIONSEA-ST36 or EA-LI4 could regulate the NPY in thalamus and SS in colonic tissue, the former could affect blood level of SS as well. It is deemed that NPY and SS may be the key substances for regulating the action of acupuncture in the brain-intestinal axis; their different levels could be regarded as an indicator for the functional difference between the acupoints.

OBJECTIVETo sought to engineer and characterize a biodegradable nanoparticles (NPs) containing rapamycin which use poly (lactic-co-glycolic) acid (PLGA) as the carrier matrix and to assess its in vivo release characteristics by local drug delivery system intravascularly.

METHODSRapamycin-loaded PLGA NPs were prepared by an emulsification/solvent evaporation technique, and NPs size distribution was assessed by submicro laser defractometer. The particle morphology was observed by scanning electron microscopy. In vitro release from the NPs was performed in TE buffer at 37 degrees C under rotation utilizing double-chamber diffusion cells on a shake stander. In vivo NPs intravascular local delivery were performed by DISPATCH catheter in New Zealand rabbit abdominal aorta and Chinese experimental mini-pigs coronary artery models.

RESULTSBiodegradable rapamycin loaded PLGA NPs were constructed successfully by emulsification solvent-evaporation technique. The diameter of rapamycin-PLGA NPs was around 246.8 nm with very narrow size distribution, and rapamycin-NPs showed good spherical shape with smooth uniform surface. Rapamycin loaded in NPs were around was 19.42%. Encapsulation efficiency of drug was over 77.53%. The in vitro release of rapamycin from NPs showed that 75% of the drug was sustained released over 2 weeks and controlled release in a linear pattern. After a single 10 minutes infusion of rapamycin-PLGA NPs suspension (5 mg/ml) under 20.27 kPa through DISPATCH catherter in vivo, the mean rapamycin levels at 7 day and 14 day were (2.438 +/- 0.439) and (0.529 +/- 0.144) microg/mg of the dry-weight of the artery segments (2 cm) which local delivery were administrated.

CONCLUSIONSPLGA NPs controlled drug delivery system for intraarterial local anti-proliferative drug delivery can potentially improve local drug concentration and prolong drug residence time in animal model in vivo. It should be appropriate for further study of its therapy efficiency in human.
