Journal of Clinical Neurology 1995;0(04):-
Objective To compared the condition of DSA and MRA for detection the lesion vessels in elder patients with recurrent ischemic cerebrovascular disease(ICVD).Methods 52 patients with ICVD,including 41 cases of cerebral infarction(CI) and 11 cases of transient ischemic attack(TIA) were detected by DSA,and the 44 cases of them were detected by MRA too.Results The vascular anomalies were detected in 43 cases(82.69%) of the 52 patients by DSA.Among them,39 cases(75%) had vascular stenosis,in which 31 cases(75.61%) were CI,and the other 8 cases(72.73%) were TIA.The aneurysm were founfd out in 2 cases,and vascular dysplasia and variation were also found in each 1 case by DSA.The vascular stenosis were found in 10 cases(22.73%) of 44 patients by MRA,in which 8 cases(18.18%) were CI,while 2 cases(4.55%) were TIA.The detection rate of lesion vessels in DSA was significantly higher than that in MRA(P

AIM: To elucidate the role of NO in the effect of tetramethylpyrazine (TMP) on vasomotion of arterioles induced by noradrenalin(NA).METHODS: Albino rabbits were anesthetized,respiration were maintained,the arterial pressure were measured with a pressure transducer attached to a polyethylene canula in the left common carotid artery,the intestinal loop was mounted on the stage of an inverted microscope and bathed in balanced solution.The inside diameter of the arterial was manually measured on a TV monitor using the TV camera mounted on the microscope.RESULTS: Topical applicated NA to measured field inducd spontaneous vasomotion which has frequency and amplitude.TMP inhibited vasomotion in vasodilation. Treatment with L-NMMA did not affect the effect of TMP.CONCLUSION: L-NMMA can not inhibit action of TMP on vasomotion,TMP may act on smooth muscle directly, not through endogenous NO.

Objective:The aim of this study was to observe the role of NO in the action of tetramethylpyrazine (TMP) on arterioles vasomotion induced by noradrenaline (NA), in order to make further understand of vasodilation mechanism of TMP.Methods: Albino rabbits weighting 2.0 ~ 2.5 kg were anesthetized. They were ventilated with room air via tracheotomy tube. The arterial pressure was monitored with a pressure transducer attached to a polyethylene canula in the right common carotid artery by four channel polygraph, the intestinal loop was mounted on the stage of an inverted microscope and bathed in balanced Kreb Ringer solution maintained at 37.5 ?C . The inside diameter of arterioles were measured manully on a TV monitor using a TV camera mounted on the microscope. Observe the changes of BP、 microcirculation and filtration of true capillary after injection of TMP 8mg/kg、 N G monomethyl L arginine( L NMMA) 10mg via a cannula in the left carotid artery after topical application of NA(0.8?g) conducted in the measured field. Results:TMP can inhibit spontaneous vasomotion in vasodilation; L NMMA can inhibit it in vasoconstriction stage. L NMMA have no effect on the action of TMP. Conclusions: Endogenous NO has no role in TMP's vasodilation.

Objective:To analyze the job preference of doctors at township health center ( THC) and provide references for formulating effective policy. Methods:238 cases of doctors were sampled from Shandong, Anhui and Shaanxi provinces. Using a discrete choice experiment, we analyzed the data with a conditional logit model. Results:The most important job attribution was salary, followed by education for children, permanent post, work location, training opportunity, and years before promotion. The OR value of the monthly income of 8 000 yuan is 7. 0 compared to 2 000 yuan. Doctors will pay 3 857 yuan and 3 294 yuan respectively for better education for children and perma-nent posts. Monthly income increasing to 8 000 yuan will reduce the quitting rate from 35% to 8%, and providing better education for children and permanent posts will reduce 5%. The permanent posts at township health center and non-permanent posts in county hospital have the same appeal to the doctor. Conclusion:When choosing a job, doc-tors at THCs valued salary the most. Improving the education level for children can be beneficial for attracting and re-taining doctors at THCs. A permanent post is more attractive to doctors than non-permanent posts at THCs.

AIM: To assess the relative agreement of GAT and NCT in IOP measurement by comparing the differences between Goldmann applanation tonometer (GAT) and non-contact tonometer (NCT) in intraocular pressure (IOP) detection.METHODS: IOP of 529 eyes of 265 volunteers were measured with both NCT and GAT, respectively.RESULTS: The measurement results of NCT were lower than that of GAT, there was significant difference between the IOP measured with NCT and GAT (19.13 vs23.43, t=22.644, P<0.05). With the increasing of IOP values, the difference magnitude was greater, especially in IOP group that was more than 30mmHg, but the correlation coefficient became lower.CONCLUSION: The measurement results with NCT are lower than that of GAT. When the IOP with the NCT is in borderline value, it need be corrected with GAT, in order to discover the pathologically elevated IOP and avoid the misdiagnosis and mistreatment of glaucoma.

Objective To investigate the predisposing factors and clinical features of disseminated herpes zoster, and to explore factors influencing postherpetic neuralgia. Methods Clinical data were collected from 53 patients with disseminated herpes zoster and 809 patients with common herpes zoster between 2012 and 2015, and analyzed retrospectively. Logistic regression analysis was used to assess factors influencing the occurrence of and pain intensity in disseminated herpes zoster, as well as the occurrence of postherpetic neuralgia. Results No significant difference in patients′age was observed between the disseminated and common herpes zoster groups(56.66 ± 17.24 vs. 56.50 ± 15.51 years, t=0.071, P>0.05), but there was a significant difference in the gender ratio between the two groups(χ2 = 8.16, P = 0.004). The incidence rates of bullae, pustules and fever were all significantly higher in the disseminated herpes zoster group than in the common herpes zoster group(15.09%vs. 3.58%,χ2=16.04, P<0.01;47.17%vs. 26.82%,χ2=10.20, P<0.01;30.19%vs. 8.03%,χ2=28.68, P<0.01). The disseminated herpes zoster group also showed significantly higher pain scores at admission compared with the common herpes zoster group (Median[P25- P75]: 6[4- 7.5] vs. 5[3- 7], Z =-3.460, P = 0.001). Logistic regression analysis revealed that gender, age, fatigue and HIV infection were significantly associated with the occurrence of disseminated herpes zoster (all P<0.05). Additionally, HIV infection(OR=5.570, 95%CI:1.196-25.939, P=0.029), gender(OR=0.166, 95%CI:0.029-0.945, P=0.043), age(OR=1.064, 95%CI:1.010-1.119, P=0.019)and the number of days that antiviral therapy lasted(OR=0.669, 95%CI:0.505-0.885, P=0.005)were all factors influencing the occurrence of postherpetic neuralgia. Conclusion Male, old age, fatigue and especially HIV infection are risk factors for the occurrence of disseminated herpes zoster, and male, old age and antiviral therapy duration may be associated with the occurrence of postherpetic neuralgia.

A 2-month-and-20-day-old girl was hospitalized because of slow weight gain for 20 days.The patient was diagnosed as anemia,pneumonia and neutrophils firstly,and showed no improvement during anti-infective therapy,blood transfusion,and leukopenia drugs.The urinary organic acid spectrum of the patient showed increased methylmalonic acid slightly,but the normal value was found by 4 tests,which was inconsistent with the typical methylmalonic aciduria.By analyzing clinical manifestations and plasma homocysteine,folic acid and vitamin B12 levels,she was considered to have intracellular cobalamin metabolic disorder.Then,normal diet,intramuscular injection of vitamin B12,and feeding calcium,betaine,and L-carnitine were given,and the girl's symptoms were improved significantly.Latter gene analysis further showed that the patient had methylmalonic aciduria CblC type.Clinical manifestations of methylmalonic aciduria are complex and individually various,different therapies showed be applied to different causes.The value of urinary methylmalonic acid level alone cannot judge etiology;diagnosis should be based on blood amino acids and carnitine spectrum,homocysteine level and vitamin B12 level.
