Objective To explore the relationship between intercranial hemodynamics and nitric oxide(NO),endothelin(ET),nailfold microcirculation in patients with migraine.Methods 50 patients with migraine and 40 normal controls underwent the measurement of intracranial hemodynamics,naifold microcirculation and the level of plasma ET,NO.The results of the two groups were compared and analyzed.Results The blood flow velocity of intracranial arteries was significantly higher in the patients than that in the normal controls( P

Objective To study the protective effects of aqueous extract and alcohol-soluble extract of Isodon lophanthoides var.gerardianus (Benth.)Hara (ILVG) on immunity hepatic injury induced by concanavalin A (Con A) in mice.Methods One hundred and eight NIH mice were allocated into normal control group,model group,ILVG groups of aqueous extract and alcohol-soluble extract (low-,middle-and high-dosage),and bifendate group randomly.In the experimental groups,mice received either ILVG aqueous extract or alcohol-soluble extract (18.20 g?kg-1,9.10 g?kg-1,4.55 g?kg-1 respectively) or Bifendate (45 mg?kg-1) by gastric perfusion daily for consecutive 5 days.In the 5th day,Con A (20 mg?kg-1) was injected into mice via the tail vein 4h after administration.And then the blood was obtained by picking out the eyeball and the serum was separated after 8-hour fasting.The serum levels of ALT and AST were analyzed,the body weight as well as the weight of liver,spleen and thymus were measured,and pathological features of hepatic tissue were observed.Results ILVG can decrease the ALT and AST,restrain the enlargement of liver and the shrinkage of thymus and reduce the necrosis of hepatic tissue.Conclusion Aqueous extract and alcohol-soluble extract of ILVG possess the effects of protecting liver from immunity injury induced by Con A in NIH mice.

Traditional Chinese medicine (TCM) has its advantages in a combination of multi-target and multi-channel overall treatment. However, its mechanism is still unclear. This article elaborated upon prior research results by analyzing the effect of property, efficacy of Chinese materia medica (CMM), acupuncture and moxibustion on mitochondria. TCM can improve the morphology and structure of mitochondria. It was involved in a series of metabolic processes, which included the energy metabolism regulation, inhibition of cell apoptosis, and resistance of oxygen free radicals in mitochondria. The results showed that there existed a certain correlation between intracellular targets of TCM and mitochondria.

?AIM:To investigate and analyze diabetic retinopathy ( DR) in patients with type 2 diabetes in local community and risk factors of type 2 diabetic retinopathy, and to provide reference for the prevention and treatment of diabetic.?METHODS:Randomly 268 cases with type 2 diabetes from community health management files from January to March 2015 were selected. Fundus photography was read through the remote reading system, demographic data and laboratory indexes of DR were analyzed.?RESULTS:In the 268 cases with type 2 diabetes, 85 cases were diagnosed as DR ( 31. 7%); there were statistical difference on gender, duration, systolic blood pressure, fasting glucose, glycosylated hemoglobin A1c, urine creatinine between patients with DR and without ( P<0. 05 ). Multivariable Logistic regression analysis showed, duration, systolic blood pressure, fasting glucose, glycosylated hemoglobin A1c were independent risk factors of DR(P<0. 05).?CONCLUSION:Long duration, high blood pressure, high blood glucose are main risk factors of DR, we should strengthen the monitoring of blood pressure, blood glucose and prevent the happening of the DR.

Objective To explore the value of SOD activity in diagnosis of central nervous system leukemia (CNSL )by detec-ting SOD activity of cerebrospinal fluid of patients with CNSL .Methods The cerebrospinal fluid of 55 patients from department of hematology of Nanfang hospital of southern medical university were collected from January 2008 to January 2009 ,in which 30 pa-tients suffered with central nervous system leukemia (CNSL group) ,the other 25 patients suffered with acute leucemia without im-paired central nervous system(control group) .The SOD activity of cerebrospinal fluid was detected by the xanthine oxidase meth-od ,while the routine test ,biochemistry test and cell smear of cerebrospinal fluid was detected .Results There were statistics differ-ence in the level of white cell and protein in cerebrospinal fluid between CNSL and control group (P<0 .05) ,but with no difference in the level of cerebrospinal fluid pressure ,glucose ,chlorine(P>0 .05) .There was statistics difference in the level of SOD activity between CNSL and control group(P<0 .05) .The white cell quantity and the protein level in cerebrospinal fluid had negative corre-lation with the activity of SOD ,(r=0 .871 ,P=0 .000 ;r=0 .518 ,P=0 .003) .The activity of SOD in the cerebrospinal fluid had sta-tistics difference before and after intrathecal chemotherapy (P<0 .05) .The activity of SOD in the cerebrospinal fluid whose under 45 year-old (755 .64 ± 345 .77) ,which was significant lower than that of the paitents whose equal with or above 45 year-old (1 420 .49 ± 307 .69)(P<0 .05) .Conclusion The changes of the SOD activity in the cerebrospinal fluid had relation with central nervous system leukemia ,and the SOD activity might be a auxiliary diagnosis index used in central nervous system leukemia by revi-sing age factor .

OBJECTIVETo observe effects of different interference orders of acupuncture and exercise therapy on the therapeutic effect.

METHODSThe patients of hemiplegia after stroke in the stage of recovery were randomly divided into two groups: raising handclasp of Bobath after electroacupuncture at Quchi (LI 11) and Hegu (LI 4) on the affected side or electroacupuncture at Quchi (LI 11) and Hegu (LI 4) on the affected side after raising handclasp of Bobath. The changes of SEP on the affected side were recorded and compared.

RESULTSSEP on the affected side significantly increased in the patients after treatment of simple electroacupuncture or exercise therapy (P < 0.01), with no significant difference between the two groups (P > 0.05). There was a very significant difference in SEP on the affected side between the group of exercise treatment after electroacupuncture and the group of electroacupuncture after exercise therapy (P < 0.01).

CONCLUSIONBoth electroacupuncture and exercise therapy can immediately improve SEP of the patient in the recovery stage, and the groups of the different interference orders of electroacupuncture and exercise have different effects on SEP, and raising handclasp of Bobath after electroacupuncture is better for improvement in cerebral function of the patient.

AIMTo study the effects of the 50 Hz-filter circuit in a microelectrode amplifier on cardiac action potential waveform and parameters.

METHODSCardiac action potential signals were fed into a microcomputer through a glass microelectrode, a microelectrode amplifier, a differentiator and A/D converter. The cardiac action potential signals were recorded and analyzed with 50 Hz-filter circuit and without it, and the frequency spectrum in the signals was analyzed with the fast Fourier transformation.

RESULTSWhen the 50 Hz-filter circuit was used, the phase 0 of the potential waveform was seriously distorted and prolonged. The maximal rate of depolarization at the phase 0 was cut down, while the other parameters were not effected.

CONCLUSIONThere has already been much 50 Hz element in the action potential waveform. During amplifying the cardiac action potential signal, the 50 Hz-filter circuit should not be turned on. Otherwise, the experiment results will be effected.
