Main acupoints were Quchi (LI 11), Baichongwo (Ex-LE), Hegu (LI 4), Sanyinjiao (SP 6), Xinjian (LR 2) and Neiting (ST 44). Among 54 patients, 23 cases recovered, 24 cases got effectiveness and 7 case had no change after the treatment. The curative effect rate was 87.0%.

Objective Vertigo is the main clinical feature and cerebral atherosclerosis is the major etiological factor and pathogenesy of posterior circulation ischemia (PCIV).The objective of this study was to observe the clinical effect of butylphthalide combined with naloxone on PCIV and hemodynamics . Methods One hundred and sixty two patients with PCIV were classified into treatment group and control group .In the treatment group , butylphthalide soft capsules were administrated by oral and naloxone 2.4 mg were administrated by intravenous drip per day .In the control group , Xueshuantong at the dose of 300 mg was given by intravenous drip per day.All the treatment lasted for 14 days.Transcranial doppler (TCD) examination was performed for all patients before and after the treatment.The mean velocity (Vm) and the systolic velocity (Vs) of bilateral vertebral arteries were recorded .Clinical cure rate was evaluated . Results Basilar artery Vm and Vs increased after treatment in the control group compared with those before treatment ([30.15 ±3.84])cm/s vs ([26.95 ±3.72])cm/s, ([40.87 ±4.54])cm/s vs ([37.16 ±4.72])cm/s.Basilar artery Vm and Vs increased after treatment compared with before treatment in the treatment group ([34.47 ±3.53]) cm/s vs ([27.53 ± 3.68])cm/s, ([42.25 ±5.29])cm/s vs ([35.87 ±4.85])cm/s, (P<0.05).Basilar artery Vm and Vs increased in the treatment group compared with the control group after the treatment ([34.47 ±3.53])cm/s vs ([30.15 ±3.84])cm/s, ([42.25 ±5.29])cm/s vs ([40.87 ±4.54])cm/s, (P<0.05).The cure rate and total effective rate in the treatment group (58.8%, 93.8%) were higher than thoes in the control group, respectively (31.7%, 75.6%)(P<0.05). Conclusion Butylphthalide soft capsules combined with naloxone have definite clinical curative effect and few side for PCIV treatment.

Objective: To investigate the feasibility of chitin as bone substitute material and carrier of rhBMP2.Methods: Porous chitin and chitin/rhBMP2/collagen complex were implanted into calvarial defects in 8 rabbits. Bone repairing ability was assessed by radiographic and histological observation. 2 rabbits without implantation were served as controls. Results: Chitin had certain bone conductive ability. When combined with rhBMP2,a complex possessing both bone conductive activity and bone inductive activity was produced. The complex had greater bone repairing ability than chitin alone. Conclusion: Chitin may be used as a bone substitute material and carrier of BMP. But its mechanical strength and surface activity should be improved.

Objective To compare the clinical results of surgical and conservative treatment of acute patellar dislocations.Methods Retrospective analyzed the clinical data of 35 patients with acute patellar dislocations from June 2004 to October 2009,and divided the patients into 2 groups.One group with 18 patients underwent surgical treatments,and the other group with 17 patients underwent conservative treatments,record the number of relapses cases of both the two groups.A radiographic examination was performed in the evaluation of the patients,and the Kujala questionnaire was applied with the intention of analyzing the improvement of pain and quality of life.Results All patients were followed up for more than 12 months.(1) The conservative treatment group exhibited a higher number of recurrent dislocations (7 patients) (41.2％) than the surgical treatment group,which did not have any relapses (x2 =9.265,P =0.002).(2) The patellar tilt returned to normal in the surgical group,while 8 patients returned to normal in the conservative group,with statistical difference between groups (x2 =10.980,P =0.001).And the lateral shift ratio returned to normal in the surgical group,while 6 patients returned to normal in the conservative group,with statistical difference between groups(x2 =7.667,P =0.006).(3)The surgical treatment group obtained a significantly better mean score on the Kujala test than preoperative ((90 ± 5) vs.(58 ± 6),t =16.465,P ＜ 0.01) ; The conservative treatment group,compared with the preoperative,is not improved obviously ((72 ± 6) vs.(62 ± 8),t =0.943,P ＞ 0.05) ;Postoperative group comparison,surgical group was higher than that in conservative group,there was significant difference between two groups (t =12.256,P ＜ 0.01).Conclusion For acute patellar dislocation,surgical treatment can significantly restore patellar stability,improve the function of knee joint.

Objective To evaluate the changes in and the regularity of brainstem evoked potentials (BA-EPs) in Parkiuson's disease (PD) as an objective criterion for early diagnosis and assessment. Methods Thirty-five healthy SD rats were divided into two groups at random. Twenty-two rats were in the experimental group and 13 in the control group. The rats were injected with 8 μg of 6-OHDA solution in the right substantia nigra pars compacta (SNc) and the right ventral tegmentum area (VTA) to create a PD model. The BAEPs of the rats in the experimental group were recorded in a quiet shielded room before the 6-OHDA injection, and one week and two weeks after injec-tion. The control group rats were injected with saline (Ns) and their BAEPs were recorded at the corresponding times. One week and two weeks later, the model rats were injected with apomorphine (APO) and their rotating cycles were counted. Results The Ⅱ , Ⅳ, andV PLs and the Ⅲ-Ⅴ IPLs on the fight ears of the experimental group were prolonged significantly compared with the control group one week after APO injection. There was no significant differ-ence in the BAEPs of the left ears after the first week. After two weeks, the Ⅱ , Ⅳ, and Ⅴ PLs and the Ⅲ-Ⅴ, and Ⅰ-Ⅴ IPLs of the right ears in the experimental group were prolonged significantly compared with the controls and the Ⅳ, and Ⅴ PLs and the Ⅲ -Ⅴ , and Ⅰ-Ⅴ IPLs on their left ears were prolonged significantly. Conclusion In the early course of a PD model in rats, their BAEPs show abnormal changes, which indicates that BAEP could be an ob-jective criterion for early diagnosis and assessment of PD. BAEP may serve as one index of damage in PD. The Ⅲ-Ⅴ PL and Ⅰ-Ⅴ iPL are sensitive indices of PD.

Objective To explore the effect of Taijiquan on motor function and depression in patients with post-stroke depression. Meth-ods From January to October, 2015, 60 stroke patients with depression were randomly divided into control group (n=30) and Taijiquan group (n=30). Both groups accepted routine rehabilitation, while Taijiquan group accepted another training of six actions from simplified Taijiquan. They were assessed with Fugl-Meyer Assessment (FMA), Barthel Index (BI) and Hamilton Depression Rating Scale (HAMD) be-fore, and four and eight weeks after treatment. Results The scores of FMA and BI increased more in Taijiquan group than in the control group after treatment (t>2.351, P<0.05), while the score of HAMD decreased more (t>2.169, P<0.05). Conclusion Taijiquan can relieve the depression and improve the motor and activities of daily living in patients with post-stroke depression.

Objective To determine the optimum dose of dexmedetomidine administered locally through evaluating the effects of different doses of dexmedetomidine on the median effective concentration (EC50) of ropivacaine for brachial plexus block.Methods American Society of Anesthesiologists physical status Ⅰ or Ⅱ patients of both sexes, aged 19-50 yr, weighing 50-80 kg, scheduled for elective ulna and radius fracture open reduction and internal fixation, requiring ultrasound-guided axillary brachial plexus block, were randomly assigned into 4 groups using a random number table: control group (group C) and dexmedetomidine 0.4, 0.6 and 0.8 μg/kg groups (D1 , D2 and D3 groups).Axillary brachial plexus block was performed only with ropivacaine in group C.In D1-3 groups, axillary brachial plexus block was performed with the mixture of ropivacaine and dexmedetomidine 0.4, 0.6 and 0.8 μg/kg, respectively.The effective block was defined as complete loss of pain sensation in the areas innervated by the brachial plexus.The volume of local anesthetics was 40 ml.The concentration of ropivacaine was determined by up-and-down technique.The initial concentration was 0.4％ and the ratio between the two successive concentrations was 1.0.If the block was effective, the next patient received a lower dose of ropivacaine;or conversely if ineffective, a higher dose was given in the next patient.At least 7 independent crossover pairs were observed in each group.The EC50 of ropivacaine was the mean of the concentration of ropivacaine of each crossover pair.The occurrence of brachial plexus block-related adverse events, adverse cardiovascular events and over-sedation was recorded.Results In C, D1, D2 and D3 groups, 20, 22, 24 and 19 patientswere enrolled, respectively.Compared with group C, the EC50 of ropivacaine was significantly decreased in D2 and D3 groups, and no significant change in the EC50 of ropivacaine was found in group D1.No patients developed adverse events in group D1.The incidence of bradycardia was 17％, but it was transient in group D2.In group D3, the incidence of bradycardia and hypotension was 58％ and 32％, respectively, and they required special treatment, and the incidence of over-sedation was 10％.Conclusion The optimum dose of dexmedetomidine is 0.6 μg/kg when mixed with ropivacaine for brachial plexus block.

One hundred children aged 8-10 years and 100 adults aged 18-45 from their families in three townships Baoshan,Mingcheng,and Yantongshan of Panshi city,Jilin province were selected in April 2009. In addition,50 pregnant or lactating women,and their 50 infants aged 0-2 years were selected.The median level of iodine in salt at household was 30.2 mg/kg and that of drinking water was 2.8 μg/L.The median levels of urine iodine in school age chidren ( 196.5 μg/L),during pregnancy( 198.5 μag/L),lactation( 224.9 μg/L),and in infants (209.0 μg/L) all were optimal according to World Health Organization criteria.Only the median urine iodine in adults ( 269.0 μg/L) was more than adequate.The prevalence of goiter evaluated by B-ultrasound was 1.8％ in 8-10year-old children.The incidences of various thyroid dysfunctions were low in these residents,such as subclinical hyperthyroidism ( 2.1％ ),subclinical hypothyroidism ( 1.5％ ),and hyperthyroidism ( 1.2％ ). Subclinical hypothyroidism occurred mostly in adults (2.7％),pregnant women ( 1.7％ ),and lactating women ( 1.8％ ) ; and subclinical hyperthyroidism occurred mostly in 8-10 years old school chidren (4.5％) and lactating women (3.6％).These results show that the current iodized salt content has no harmful effect on thyroid function of rural residents in Jilin province.
