BACKGROUND:The establishment of animal models of Parkinson’s disease plays an important role in clinical and basic experiments of Parkinson’s disease, and its stability directly affected study results. OBJECTIVE:To evaluate the behavior and pathological changes of rats with Parkinson’s disease established by unilateral two-point injection with 6-hydroxydopamine.
METHODS:A total of 62 Sprague-Dawley rats were randomly assigned into experimental group (n=50) and normal group (n=12). Using stereotatic technique, 6-hydroxydopamine was injected into the right substantia nigra
RESULTS AND CONCLUSION:At 2 weeks, after induction with apomorphine, left rotation speed>7 r/min was observed in only 22 rats of the experimental group. No significant difference in the number of rotation between 2 and 4 weeks was detected (P>0.05). Tyrosine hydroxylase and dopamine content significantly reduced in the model group. Results indicated that unilateral two-point injection of 6-hydroxydopamine could be used to
successful y establish rat models of Parkinson’s disease with similar behaviors and pathologies.

Objective To analyse the mental health status of doctors in the First Affiliated Hospital of Xinjiang Medical University. Methods The 673 doctors in different clinic character in the First Affiliated Hospital of Xinjiang Medical University were investigated by questionnaire and symptom checklist-90(SCL-90),and estimate the results through F-test and t-test . Results Doctors in SCL-90 in addition to interpersonal relationships(1.59±0.49, t=-1.02,P>0.05) and the rest of the factors:somatization (1.48 ± 0.55, t=2.32), force(1.75 ± 0.43, t=2.34),depress(1.67 ± 0.44,t=3.00), anxiety(1.55 ± 0.57, t=3,71), hostility(1.76±0.47,t=5.65),horrible(1.48±0.32,t=6.35),stubborn(1.65±0.39, t=4.04),insanity(1.43±0.46, t=3.39)are higher than the national norm, there is statistical difference (P<0.05). In different gender groups, in addition to the somatization and forced, female doctors other project factors were higher than male doctors, including interpersonal relationships(1.62 ± 0.37, 1.56 ± 0.41), hostility factor(1.79 ± 0.38, 1.73 ± 0.43) differences were statistically significant (t=2.15, t=2.07, P均<0.05). In different professional title ,Doctors with primary professional title in addition to the body of the rest are higher than the title doctor. Anxiety factor differences have statistical significance in different groups (F=2.73, P<0.05). In different department , Emergency department and pediatric clinicians in addition to depression, anxiety and other factors of points were higher than those of physicians and surgeons, the difference in interpersonal relationship factors have statistical significance in different groups (F=4.54, P<0.05). Conclusion The scores aboutdoctors, SCL-90 in the First Affiliated Hospital of Xinjiang Medical University in addition to interpersonal relationships, the rest of the factors are higher than the national norm ,showing that clinic doctors were in psy chological sub health state, especially in female doctors, primary professional title dortors and Emergency department and pediatric clinicians.

Objective To evaluated the effect of special nursing after coronary intervention in elderly.Methods 142 cases of consecutive patients with coronary artery disease were treated with percutaneous coronary intervention.According to the nursing models,the patients were divided into special nursing group(86 case) and routine nursing group(56 case).Results The incidence of aypnia,dysphoria,hospital onset of infection or other complication after intervention in special nursing group was less than that of routine nursing group.Conclusion The special nursing may accelerate the recovery of the old patients with coronary artery disease after coronary intervention.

Objective To investigate the prognostic factors in acute myeloid leukemia subtype M2 (AML-M2) patients with chromosome translocation of 8 and 21. Methods By using G-banding analyses karyotype and combining the clinical data, prognostic factors in 94 cases of de novo adult AML-M2 in our hospital from 2001 to 2007 were retrospectively analyzed. Results Chromosome 8 and 21 translocation were identified in 53.2 % (50/94) of AML-M2 cases. In the patients with other aberrations in addition to t(8;21), their complete remission (CR) rates, overall survival (OS) was lower than the patients with sole t (8;21) and normal karyotype(P <0.05). And the patients with sole t (8;21) whose CR rates and OS had no difference with patients with normal karyotype (P>0.05). The patients were divided into 3 subgroups (low index, less than 2.5;intermediate index, 2.5-20;high index, 20 or more) according to WBC index. The CR had no difference among the 3 subgroups, but the OS of the 3 subgroups was different (P<0.05). The OS in the lowest index group was longer than that in the others. Conclusion Cytogenetically, 53.2% cases had chromosome 8 and 21 translocation, 46 % cases had t(8;21) with additional chromosomal abnormalities, and the main additional abnormalities were loss of a sex chromosome (LOS). t(8;21) AML-M2 patients with additional chromosome abnormalities had low complete remission rate and shorter survival time, and its prognosis was poorer. WBC index have no influence on complete remission rate but effected the survival time.

Objective To test the mutation locus of uridine diphospho-glucuronosyltransferase gene (UGT1A1) in a Chinese patient with Crigler-Najjar syndrome type Ⅰ and her family members,analyzing the genetic characteristics of the pedigree.Methods Genomic DNA was extracted from the patient and her family members and other 50 full-term infants with normal serum bilirubin as a healthy control group.Fifty cases of full-term newborn whose serum bilirubin level were nomal were study as controls.The promoter and all exons of UGT1A1 gene were amplified by the method of polymerase chain reactions (PCR),and mutations were identified by direct sequencing.Results The propositus and her miscarriage sister were homozygous for a nonsense mutation at nucleotide number 715 (715C ＞ T) in exon 1 of gene UGT1A1,substituting of stop codon (TAG) for glutamine (CAG) at position 239 (Q239X).The other 5 members were heterozygous in the same mutation locus.A TA insertion mutation and a G71R mutation in exon 1 were observed in the family members.The patient and her sister were homozygous of A(TA)7TAA mutation while other four were heterozygous.Propositus,grandmother,mother and her younger brother were heterozygous of G71 R mutation.No mutation was found in exons 2-5.No mutation was found in other fifty healthy cases in the healthy control group.Conclusions Q239X homozygous mutations is considered to be the lethal gene in this Crigler-Najjar syndrome family.Collaborative G71 R and A(TA)7TAA mutations may further reduce the enzyme activity of UGT1A1,causing varying degrees of bilirubin disorder.

Objective To investigate the effect factors for language and memory dominance testing in propofol Wada test in refractory epilepsy patients.Methods From January 2010 to August 2013,total of 23 patients underwent propofol Wada tests for language and memory dominance evaluation.According the performance in language test and memory test,the patients were divided into two groups,respectively:succeed with test or failed in test.The relevant factors including age,duration of epilepsy,handedness,FIQ (full scale of intelligence quotient),lateralization of lesions,language dominance,dose of propofol and the adverse effects of propofol were recorded as independent variables.Logistic regression was adopted to screen the effect factors for memory dominance evaluation.All statistical analyses were processed with SPSS software.Results All 23 patients succeeded with language test,but only 13 patients succeed with memory test.The difference of success ratios between language test and memory test was significant (P=0.001).For memory test,the difference of duration of epilepsy and FIQ in success group and failed group was significantly different (duration of epilepsy:(10.57±4.68) vs (18.30±9.30),P=0.032,FIQ:(81 ±25.33) vs (64.2±10.86),P=0.046).More grade Ⅱ adverse effects of propofol occured in the patients who failed in memory test (P=0.011).Logistic regression results indicated the grade Ⅱ adverse effects of propofol were the main risk factor for memory test failure (OR=28.0,P＜0.01).Conclusions Propofol Wada test is an effective method for language dominance evaluation.However,the effect factors for memory dominance evaluation are much more than language evaluation,such as duration of epilepsy,FIQ and grade Ⅱ adverse effects of propofol,and grade Ⅱ adverse effects of propofol may be the most significant risk factor.

Hepatic nodules in patients with Budd-Chiari syndrome (B-CS) are identified in clinical work and the differentiating diagnosis is very important for making the treatment strategy.Most B-CS patients with hepatic nodules have nonspecific clinical manifestations.Ultrasonography,computed tomography and magnetic resonance imaging are often used for differentiating diagnosis.According to the results of retrospective study on clinical and imaging data of 51 B-CS patients with hepatic nodules,we draw a conclusion that the differentiating diagnosis of hepatic nodules in patients with B-CS depends on imaging characteristics.Different treatment strategies are adopted according to the comprehensive analysis of these imaging data and satisfactory results can be achieved.

Simvastatin,a 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitor,is widely prescribed to patients with hypercholesteremia and its muscular toxicity has been widely reported.The metabolism of simvastatin depends on the enzymic activity of cytochrome P450 3A4 (CYP3A4) and inhibitors of CYP3A4 can result in clinical events by interacting with simvastatin.Diltiazem is a moderate inhibitor of CYP3A4,which is known to increase the serum concentration of simvastatin.Here we report a patient with unrecognized hypothyroidism who had been stable for more than one year on low-dose simvastatin therapy of hypercholesteremia and rhabdomyolysis occurred with the addition of diltiazem.This is one of scanty reports of rhabdomyolysis induced by simvastatindiltiazem drug interaction,especially in hypothyroid patient.This case reminds the clinicians that although diltiazem as a moderate CYP3A4 inhibitor can be used cautiously with small doses of CYP3A4-dependent statius (eg,simvastatin),these two commonly used drugs should be avoided in hypothyroid patient.

Objective To examine the association of serum 25-hydroxyvitamin D levels with arterial stiffness and left ventricular hypertrophy (LVH) in elderly hypertension patients.Methods We recruited 166 elderly patients [mean age,(80.8 ± 6.2) years] with primary hypertension.Arterial stiffness was assessed by carotid femoral pulse wave velocity (cfPWV).Left ventricular mass index (LVMI) was determined according to the Devereux formula.Based on serum 25-hydroxyvitamin D levels,the patients were divided into two groups,the low 25-hydroxyvitamin D group (＜20 μg/L)and the high 25-hydroxyvitamin D group (≥20 μg/L).Results Faster cfPWV and larger LVMI values were observed in the low 25-hydroxyvitamin D group as compared with the high 25-hydroxyvitamin Dgroup [(15.00±3.04) m/s vs.(11.26±3.09) m/s;(120.14±25.82) g/m2 vs.(96.74±23.10) g/m2 ; t=-6.79,-5.16,respectively; both P=0.000].Multiple liner regression analysis showed that the 25-hydroxyvitamin D level was independently associated with LVMI (β=0.215,P=0.001) and cfPWV (β=-0.469,P＜0.001).Conclusions Serum 25-hyroxyvitamin D is independently associated with arterial stiffness,LVH Vitamin D may play an important role in the pathogenesis of arterial stiffness and LVH in elderly hypertension patients.
