Objective:To observe the clinical effects of tuina manipulations plus the functional training on scapulohumeral periarthritis (SP), and provide the better therapeutic plan for SP patients. Methods: A total of76 cases with SP in conformity with the inclusion criteria were randomly divided into a tuina group and an acupuncture group, 38 patients in each group. All the patients were instructed to do functional training under the guidance of the professional medical practitioners. The patients in the tuina group were treated additionally with tuina manipulations, while the patients in the acupuncture group were added with acupuncture treatment. The two groups were treated once every day. After ten sessions, the changes in the scores of visual analog scale (VAS) and Melle were observed, and the clinical effect was compared. Results:After the treatment, VAS and Melle scores were all lower in the tuina group than those in the acupuncture group, with statistical significances between the two groups (P<0.05). The remarkable effective rate was 5.3% in the acupuncture group and 21.1% in the tuina group. The remarkable effective rate was higher in the tuina group than that in the acupuncture group, with a statistical significance (P<0.05). Conclusion:Tuina manipulations plus functional training for SP can effectively alleviate pain and restore the functions of the shoulder joint, with a better effect than acupuncture plus functional training.

OBJECTIVE:How to explain and predict individual difference of artificial cochlea so as to evaluate rehabilitative effect of implant has been paid much attention by audiological scholars,clinical physicians,patients,and their relatives. This study was designed to analyze and evaluate rehabilitative status of patients accepting artificial cochlea implantation to investigate the relative influential factors of auditory rehabilitation. METHODS:A total of 28 patients were selected from Department of Otolaryngology Head and Neck,Affiliated Hospital of Qingdao Medical College from June 2002 to April 2008. They were accessed by age,time of rehabilitation training,usage of hearing aids,audiology and aural image before surgery,and NRT monitoring in cochlear implantation so as to observe auditory improvement. The clinical results were analyzed to detect the effect of various factors on auditory rehabilitation. RESULTS:Age,preoperative preparations and good audiology and aural image are important premises for a successful rehabilitation. Longer the time of using hearing aids and language rehabilitation are,and better results will get. NRT response during operation is also an important factor for good auditory rehabilitation. CONCLUSION:The influential factors of auditory rehabilitation after cochlear implant included the age,audition remains,usage of hearing aids,NRT response during operation,and the time after the cochlear implant operation.

Objective To analyse the clinical features,imaging characteristics diversity of deep cerebral veins thrombosis (DCVT).Methods From 2004 to 2013,6 patients diagnosed as DCVT were recorded and a retrospective review of the cases were undertaken for the purpose of this analysis.Results Among the 6 patients with DCVT,4 were male and 2 were female,aged from 28 to 69 years old.The disease duration of 4 cases ranged from 2 to 7 days,remnants were 20 days and 3 months respectively.The first symptoms of 4 cases were headache,1 was feeblemindedness,and the other was hemiplegia.The secondary symptoms were disturbance of consciousness,apathy,diplopia and non-infectious fever.Non-contrast computed tomography showed low signal in the bilateral thalamus in four patients,high signal in the transverse sinus and straight sinus in one patient and high signal in torcular in one patient.Abnormal signal was found in bilateral thalamus on magnetic resonance imaging in all patients and some of them had abnormal signal in the mesencephalon or basal ganglia.The patients were definitely diagnosed as DCVT by magnetic resonance venography (MRV) or digital subtraction angiography (DSA).Among them,2 patients were confirmed by brain biopsy.Four patients were followed up with good outcome and 2 were lost to follow-up.Conclusions The clinical manifestations of DCVT are not specific.For acute-onset DCVT patients,the first symptoms are always headache and vomiting,while the main symptoms are declined cognition and slow reaction for chronic-onset ones.Along with the progress,the main symptoms of DCVT are disturbance of consciousness,psychiatric symptoms and intracranial hypertension.Changes in the bilateral thalamus and basal ganglia are especially main characteristics which are easily misdiagnosed as brain tumor according to the images.DCVT can be definitely diagnosed by no signal of deep cerebral veins on MRV or DSA.

BACKGROUND: Neuron-specific enolase, γtype isoenzyme that is specially present in the cytoplasm of neurons and neuroendocrine cells, is considered as a sensitive predictor for neuronal damage.OBJECTIVE: To observe the changes of serum neuron-specific enolase in patients with transient brain ischemic attack, so as to explore its relationship with the degree of neuronal damage.DESIGN: Case-control observation.SETTING: Department of Neurology, Jinan No. 4 People's Hospital.PARTICIPANTS: A total of 29 patients who were hospitalized in the Department of Neurology, Jinan No. 4 People's Hospital, due to transient brain ischemic attack (all called for emergent medical treatment within the onset of 6 hours) between March 2002 and May 2004 were enrolled in this study. There were 18 males and 11 females with the average age of(60.36t11.67) years. According to the duration of neural functional deficits, all subjects were divided into two groups, namely, transient-symptom group (≤ 6 hours) of 19 cases and lasting-symptom group (＞ 6 hours)of 10 cases. At the same time, 25 healthy controls, 15 males and 10 females with the average age of (62.34±9.65) years, rere selected from those who came for routine health examination.METHODS: Fasting elbow venous blood of 1 mL was collected only once from the subjects in control group; the same amount of blood was collected from the patients in transient ischemic attack group immediately after hospitalization, and at days 2, 3, 4 and 5. Roche Elecsys 2010 automatic analyzer was used to detect serum neuron-specific enolase. Neuronal damage was assessed with neurological deficit scale (defined as practical recovery if scores were reduced by 90%-100%; remarkable improvement if scores were reduced by 46%-89%; improvement if scores were reduced by 18%-45%; ineffective if scores were reduced by less than 17% or even the disease aggravated).MAIN OUTCOME MEASURES: The daily changes of serum neuronspecific enolase.RESULTS: All the54 subjects remained in the final result analysis. [1]Comparison of neuron-specific enolase density: It was significantly higher in transient brain ischemic attack group than in control group [(23.53±12.35) vs(14.29±6.83) μg/L, t=2.678, P ＜ 0.01]. [2] Curve of neuron-specific enolase changes during the acute stage: It began to increase at the early stage,reached the peak level on the next day, and gradually declined to the normal level in 4-5 days. [3] The level of serum neuron-specific enolase in the two groups with various durations of neurological deficit symptoms: It was obviously higher in transient-symptom group than in control group [(19.24±8.95)vs (14.29±6.83) μg/L, t=1.893, P ＜ 0.05], and higher in lasting-symptom group than in control group [(28.87±13.15) vs (14.29±6.83) μg/L, t=4.367,P ＜ 0.001]. [4] The level of neuron-specific enolase was positively correlated with the duration of neuronal damage (r=0.815, P＜0.01).CONCLUSION: Serum neuron-specific enolase increases within a short term after transient brain ischemic attack and reaches the peak level at around 24-36 hours, suggesting that the detection of serum neuron-specific enolase has a guiding value in assessing the severity of transient brain ischemic attack.
