Objective To investigate the clinical characteristics of essential tremor (ET).Methods The clinical materials of 80 patients with ET was analysed.Results In 80 patients with ET, 50 cases for the male, 30 cases for the female,the age at tremor onset was from 3 to 70 years old,the mean age was 34.6?16.3 years old,the course of disease was 6 months to 60 years,the mean 14.2?9.9 years. 45 patients (56 3%) had postive family history,they showed mostly autosomal dominant inheritance.The postural tremor was the main manifestation of essential tremor,tremor affected hand in 92.5% patients,throat in 21.3%,head in 20%,chin in 17.5%. Functional disability and impairment in 17.5% patients because of tremor.91 2% patients had the effect of alcohol occurred in 34 cases who had performed alcohol test.6 3% patients accompanied parkinson’s disease.A small dose of propranolol was effective in 61% patients.Conclusion In the ET group,the patients were mostly young,single model,the number of the male ET cases was more than the female,sole postural tremor,part of patients might accompany PD,a small dose of propranolol was effective.

0.05). Conclusion The g.168_185del polymorphism of the promoter in DJ-1 gene does not a significant risk factor for PD in this population.

OBJECTIVE To strengthen the hospital infection control and the link management, and to improve the medical care and nursing quality. METHODS The main methods were to strengthen the organization leadership, set up and enhance the management system of infection; strengthen the continuing education about the hospital infection knowledge, control the hospital infection, and standardize medical personnel′s hand hygiene; choose the correct washing and maintenance method for the apparatus and instruments; and strengthen the management of the medical wastes. RESULTS After that to set up the management of each link, eliminate the dangers in medical action, improve the antiseptic quality, and decrease the rate of hospital infection. CONCLUSIONS The hospital infection controls and the link management are two of the important indexes of appraising the management level of the hospital, and it is the important guarantee of improving medical care and nursing quality and supporting the medical treatment′s security.

Objective To explore parkin gene deletion mutations at exons 3 to 7 in Chinese familial patients with Parkinson's disease as well as the association with the clinical features.Methods DNA was extracted from 6 unrelated families of PD patients; the deletion mutations of parkin gene at exons 3 to 7 were identified by PCR amplification, agarose gel electrophoresis. and the clinical data were analyzed together with the above information.Results In the 6 unrelated families of PD patients, 1 case had exon 5 deletion, its hereditary manner was autosomal recessive inheritance,the patient's age at the onset was 60 years old,clinical feature was tremor,rigidity and bradykinesia,but no athetosis.In addition the deletion mutations of parkin gene at exons 3,4,6,7 were not found.Conclusion There are deletion mutations of parkin gene at exons 5 in families PD of Chinese patients.

Objectives To investigate the DRD 2 genetic susceptibility to essential tremor(ET) in Chinese.Methods Polymerase chain reaction-restricted fragment length polymorphism(PCR-RFLP) was used to determine the DRD 2 Taq ⅠA genotypes of 80 unrelated ET patients and 100 healthy controls.Results No significant differences in Taq ⅠA genotype and distributions of allele frequencies of Taq ⅠA loci at the DRD 2 gene were observed between ET and controls.Conclusions Taq ⅠA loci polymorphism at DRD 2 gene may be not associated to genetic susceptibility to ET,but the Taq ⅠA polymorphism at DRD gene could contribute the disorder of central dopaminergic neural system in ET.

Objective To evaluate the clinical effect of endovascular stent placement to the treatment of intracranial internal carotid artery dissection.Methods Two patients with intracranial internal carotid artery dissection received the treatment of stent placement,and 1 patient with a dissection of the supra clinoid internal carotid artery received conventional anticoagulation treatment.Results Two patients with intracranial internal carotid artery dissection were given treatment of Apollo stent placement,of which 1 patient had improvement of left limb paresis,the score of NIHSS from 3 before operation to 2 after operation; the other one with episodic left limb weakness was not seen any attack after stent placement.Another one patient without stent placement receiving conventional anticoagulation treatment had some improvement of right limb paralysis.Conclusion The treatment of endovascular stent placement to the intracranial internal carotid artery dissection has better clinical efficacy and especially used for those patients with no effect to the conventional anticoagulation treatment.

Seeds of Panax quinquefolius L. with original moisture content of 5.9%, together withthat desiccated over silica gel to moisture contents of 3.4% and 1.7%, were stored at ambient tempera-ture,-5 ℃C, -18 ℃C and -196 ℃C (liquid nitrogen) for 6 months. Influences of desiccation and storage on seed viability were tested by TTC staining, before and after desiccation, and their vigour were evaluatedon tests of seed esterase isozyme isoelectric focusing (IEF), and field test on their rate of splitting and e-mergence,length of bud and root. Results showed that there was no effects on seed viability by desiccationto 3.4% and 1.7% of moisture content, as the TTC staining rates were 100% for all seeds tested immedi-ately after desiccation. No significant differences in seed viability and vigour were detected among seedsstored at defferent temperature as there are no significant difference in vairance analysis for seed split rateand seed emergency rate.

Objective:To investigate the Repetitive transcranial magnetic stimulation combined with biofeedback non motor symptoms on clinical effects and serum levels of IL-6,CRP and TNF-α of Parkinson's disease.Methods:84 cases of Parkinson's disease in our hospital were randomly divided into experimental group and control group,with 42 cases in each group.The control group were treated with EMG and EEG biofeedback,while the experimental group were treated with repetitive transcranial magnetic stimulation on the basis of the control group.Then the serum levels of C reactive protein (CRP) and interleukin-6 (IL-6) and tumor necrosis factor alpha (TNF-α),the non motor symptoms questionnaire (NMSQuest),Parkinson's disease Sleep Scale (PDSS) and Hamilton Depression Scale (HAMD) score in the two groups were observed and compared before and after the treatment.Results:Compared with before treatment,the serum levels of CRP,IL-6 and TNF-α,the NMSQuest and HAMD in the two groups decreased after the treatment,while the PDSS score increased,and the differences were statistically significant (P＜0.05);Compared with the control group,the serum levels of CRP,IL-6 and TNF-α,NMSQuest and HAMD in the experimental group were lower,while the PDSS score was higher,and the differences were statistically significant (P＜0.05).Conclusion:Repetitive transcranial magnetic stimulation combined with biofeedback can reduce the serum levels of IL-6,CRP and TNF-α in patients with Parkinson's disease,which has better clinical effect on the non motor symptoms.

Objective To provide the data of mandible and zygomatic arch, including the space distance of mandible angles, depth and length of zygomatic arch, by direct measurement and related analysis at home position of corpse in Chinese Han for medical aesthetics. Methods The vernier callipers were used to directly measure the every indexes of mandible and zygomatic arch in the formalin-fixed male and female adult corpses (50 each) and to proceed the related analysis. Results The results showed that male mandible thickness was (12.60?1.26) mm, mandible height (33.60?3.35) mm, mandible length (77.60?7.80) mm , width of mandible ramus (34.80?3.50) mm, height of mandible ramus (67.20?6.70) mm, depth of zygomatic arch (9.54?1.19) mm, length of zygomatic arch (40.60?4.97)mm, and thickness of mandible angle (12.20?0.67) mm in male; Mandible thickness was (10.70?0.98) mm, mandible height (29.40?2.64) mm, ramus of mandible height (74.00?7.07) mm, width of mandible (31.10?3.04) mm, height of mandible ramus (64.00?5.53) mm, depth of zygomatic arch (8.67?1.09) mm, l ength of zygomatic arch (36.50?4.59) mm, and thickness of mandible angle (13.80?1.28) mm in female. Conclusions The breadth between bilateral angle of mandible could come to reckoning the depth of zygomatic arch, the length of zygomatic arch and other indexes of mandibles. Those data are useful in aesthetics and preparation of the compound.

Objective To study the impact of enteral nutrition (EN) or parenteral nutrition (PN) in postoperative colorectal cancer patients on viscera organ function and "passing wind" time.Methods Totally 30 patients with colorectal cancer joined this study with informed consent.Patients were randomly divided into EN group and PN group.Both two groups were given nutritional support from the first post-operative day to the 7th post-operative day.The pre-operative and post-operative viscera organ functions and the recovery time of gastrointestinal functions are observed.Results Total bilirubin was significantly lower in EN group than in PN group (P ＜ 0.05).The length of post-operative hospital stay was significantly shorter in EN group than in PN group (P ＜0.01).The post-operative complications were not significantly different between two groups (P ＞ 0.05).Conclusion Postoperative EN support is beneficial for colorectal cancer patient in terms of lower bilirubin levels,shorter post-operative hospital stay,and lower cost.
