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.

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.

Objective To investigate the effect of hydrogen-rich water on cerebral edema and aquaporin 1 (AQP1) expression in rats with traumatic brain injury (TBI).Methods Ninety male Sprague-Dawley (SD) rats were randomly divided into sham operation group,TBI model group,hydrogen-rich water treatment group (H group),with 30 rats in each group.TBI model was reproduced by weight dropping method.The skulls of rats in sham operation group underwent only craniotomy without direct hit and with bone wax sealed suture.5 mL/kg of hydrogen-rich water injection was given intraperitoneally after model reproduction in H group,and equal amount of normal saline was given in sham and TBI groups,once a day for both groups for 5 days.Six rats from each group were sacrificed at 6,12,24,48 hours and 5 days after evaluating neurological severity scores (NSS).The cerebral cortex was harvested,and the pathological changes in morphology of brain tissue were observed with light microscope.The positive expression of AQP1 in cerebral cortex was observed with immunohistochemistry by light microscopy,the AQP1 mRNA expression in cerebral cortex was determined by real-time fluorescent quantization reverse transcription-polymerase chain reaction (RT-PCR),and the AQP1 protein expression in cerebral cortex was determined by Western Blot.Results ① All rats in sham operation group had a NSS of zero at each time point.NSS of TBI group was obviously raised with time prolongation,and peaked at 24 hours followed by a lower tendency,while the score in H group was significantly lower than that of TBI group,and the difference was the most obvious at 24 hours as compared with TBI group (9.83 ± 2.78 vs.13.50± 2.42,P ＜ 0.05).② It was shown by light microscope that in the TBI group there were pathological changes in cerebral cortex,including obvious irregular arrangement of nerve cells,cerebral edema,obvious bleeding,especially at 24 hours,then the cerebral edema became vanished gradually;and the positive expression of AQP1 in the pia mater at all the time points in the TBI group was significantly increased,and it was most obvious at 24 hours.Compared with TBI group,the pathological changes at time points of 12 hours to 5 days in H group was significantly lessened,and the positive expression of AQP1 in the cerebral pia mater was reduced obviously.③ Compared with sham operation group,the mRNA and protein expressions of AQP1 in cerebral cortex in TBI group were significantly elevated,peaked at 24 hours [AQP1 mRNA (2-△△Ct):7.50±0.26 vs.1,AQP1 protein (gray value):1.986±0.110 vs.0.336±0.034,both P ＜ 0.05],then they gradually declined.The mRNA and protein expressions of AQP1 in cerebral cortex were significantly decreased after hydrogen-rich water treatment [24-hour AQP1 mRNA (2-△△Ct):5.40±0.21 vs.7.50±0.26,24-hour AQP1 protein (gray value):1.246±0.137 vs.1.986±0.110,both P ＜ 0.05].Conclusions The up-regulation of AQP1 mRNA and protein in ratst cerebral cortex after TBI perhaps participates in edema formation which might be involved in the pathophysiology of cerebral edema in TBI.Early treatment with an intraperitoneally injection of hydrogen-rich water is capable of attenuating the extent of TBI-induced up-regulation of AQP1 mRNA and protein,alleviating cerebral edema,and achieving its protective effects.

Objective To investigate the relationship between body mass index (BMI) and dose area product (DAP) as well as fluoroscopy time during coronary angiography (CAG) in Han nationality subjects in order to improve early judging and reducing high radiation risk. Methods CAG materials of 451 Han nationality subjects were retrospectively analyzed. The patients included 276 males (age 32-87 years) and 175 females (age 42-84 years), and the BMI values ranged from 17.30 to 35.42 kg/m2. According to BMI values, the patients were divided into group A(BMI<20 kg/m2,n=25), group B (BMI 20-24.9 kg/m2,n=204), group C (BMI 25-29.9 kg/m2,n=192) and group D (BMI>30 kg/m2,n=30). The mean DAP and fluoroscopy time of each group were calculated; the DAP values were compared between each other among the four groups by using nonparametric Kruskal-Wallis test, while the fluoroscopy time was compared between each other among the four groups by using single factor analysis of variance or LSD-t test. Results The mean DAP of group A, B, C and D was(1 070.07±541.33) μGym2,(1 326.82±606.91) μGym2,(1 937.99±1 030.31) μGym2 and (2 654.53±1 296.69) μGym2 respectively. The mean fluoroscopy time of group A, B, C and D was (3.53± 2.08) min, (2.70 ±1.80) min, (2.75 ±1.88) min and (2.71 ±1.69) min respectively. Statistically significant difference in DAP values existed between each other among the four groups (P<0.05) except between group A and group B (P=0.232). Statistically significant difference in fluoroscopy time existed between group A and other three groups (P<0.05), while the difference in fluoroscopy time between each other among B, C and D groups was not significant (P>0.05). Conclusion The DAP values of adult Han subjects receiving CAG are increased with the increase of BMI values; the fluoroscopy time is significantly prolonged in patients with BMI<20 kg/m2. In performing interventional procedure, the operator should not only understand that the increase of BMI can cause the increase of DAP, but also need to pay special attention to the increase of DAP value caused by operation difficulty when the patient’s BMI is <20 kg/m2.
