Objective To explore an effective treatment for knee osteoarthritis.Methods All patients were randomly recruited into an observation group(n=41)and a control group(n=37).The observation group was treated by warming needling.while the control group was treated by common acupuncture combined with TDP. Results The effective rate of the observation group and the control group was 90.24%and 70.27%respectively,showing significant difference(P<0.05).Conclusion The warming needling was effective in treating knee osteoarthritis.

The latest literatures on eslicarbazepine acetate in the treatment of epilepsy from home and abroad were referred. The results showed that the oral absorption of eslicarbazepine acetate is quick with long half life, linear pharmacokinetics and low potential of drug-drug interactions. Compared with carbamazepine and oxcarbazepine, eslicarbazepine acetate is more effective against epilepsy.

Referred to the latest literatures on raltegravir from home and abroad, the effect and safety of raltegravir in the treat-ment of AIDs were reviewed. The results showed that raltegravir was a necessary component for the initial treatment and repeated treat-ment of AIDs. Up till now, there was no report on its serious adverse reactions and drug interactions.

Objective To observe the effect of traditional acupuncture therapy on exercise syndrome.Methods 120 cases were randomly divided into the treating group and control group with 60 cases in each group. The cases in the treating group were treated with acupuncture after exercise, but those in the control group did not receive any treatment. The physical and chemical testing data of two groups before and after exercise were compared.Results After acupuncture treatment, the heart rate, myodynamia, blood glucose, lactic dehydrogenase and creatine phosphate kinase of the cases in the treating group were significantly different from that in the control group ( P<0.01).Conclusion The traditional acupuncture can recover body's balance quickly, and has the effect of resisting exercise fatigue.

This paper introduces and analyzes the changes of scientific understanding in the linkage of global envi-ronment and health from historical and environment perspective, emphasizing on the fact that:the environmental issue im-pacts on human health are attracting an increased attention and emphasis from the international community;the existing re-search has fully proved a clear causal relationship between environmental issues which constitute one of the major factors that lead to a variety of human diseases and human health risks;the environmental issues effects on health quantified at the global level are the highlights and difficulties in the related research, differences in the current research methods and con-clusions exist internationally, but quantitative research is popular; the integration perspective of the existing scientific knowledge and global policy is a huge challenge placed in front of the global environment and health governance.

The self-made high sensitivity and selectivity micro-biosensor was applied to monitor the change of dopamine in cerebral nucleus in rats in vivo. The micro-biosensor was prepared and used to detect dopamine level in vitro and monitor the dynamic change of dopamine in different cerebral nucleus in vivo. The results showed the lowest concentration of dopamine that could be detected by the biosensor was 32.5 nmol/L. Its positive peak was significantly different from that of AA, 5-HTP and E. The biosensor could keep working for monitoring the dopamine concentration in the cerebral tissue for more than 10 h. It was concluded that the microsensor has high sensitivity and selectivity to dopamine and can be used to dynamically monitor the change of dopamine in vivo.

Objective To investigate the structural response of diaphragm and soleus of the rat after mechanical ventilation (MV), and to explore the specific mechanism of the dysfunction of both muscles.Methods Sixteen male Sprague-Dawley (SD) rats were randomly divided into control group and MV group, with 8 rats in each group. Rats in MV group were treated with controlled ventilation and maintained anesthesia, and those in control group were only anesthetized without MV and maintained anesthesia. The diaphragm and soleus were harvested after MV for 18 hours, and the morphology changes were observed with light microscope. The cross section of muscle fiber was observed by immunofluorescence technique analysis, and the cross-sectional area of muscle fiber was calculated. The ultra structural changes in muscle fibers were observed under transmission electron microscope.Results ① Observed under light microscope, the cross section of the diaphragm and soleus muscle in the control group was regular, the nucleus was normal and the cytoplasm was homogeneous. The fibers in the diaphragm-biopsy specimens from MV subjects were smaller than those from control subjects, whereas these signs were not found in soleus. But fiber atrophy in MV specimens was not accompanied by an inflammatory-cell infiltrate. ② Under the fluorescence microscope, the control group had a smaller cross-section of the slow-twitch muscle in diaphragm, while the fast-twitch muscle fibers werelarger. As compared with diaphragm-biopsy specimens from control, specimens from MV subjects showed decreased cross-sectional areas of slow-twitch and fast-twitch fibers, respectively (μm2: 1069.00±155.24 vs. 1297.12±331.15, 2279.66±442.31 vs. 3031.80±596.11, bothP < 0.05). The disproportionate decrease in fast-twitch fibers cross-sectional areas [(70.42±3.61)% vs. (75.63±2.48)%] resulted inan increase in the percentage of total area occupied by the slow-twitch fibers [(29.58±3.61)% vs. (24.35±2.48)%, bothP < 0.01]. There were no significant differences in cross-sectional areas of slow-twitch and fast-twitch fibers in soleus between control group and MV group (μm2: 3193.80±559.36 vs. 3008.84±559.22, 3392.86±514.56 vs. 3594.35±651.67, bothP > 0.05). ③ In the control group, the muscle fibers of the diaphragm and soleus were arranged orderly, the boundary of the light and dark bands and the Z-line were clear, and there was no autophagy in the visual field. The outer membrane of the mitochondria was complete, and the cristae were in the shape of clapboard. The signs of misalignment of myofibrils, disruption of Z-line and vacuolar mitochondria were found in diaphragm from MV group, whereas these signs were not found in soleus. Diaphragm from MV group exhibited an increase in autophagic vesicles visualized by transmission electron microscopy as compared with control group.Conclusions Controlled MV for 18 hours resulted in diaphragmatic inactivity and promoted muscle injury and atrophy, while autophagy and mitochondrial dysfunction were enhanced. Soleus immobilization for 18 hours was not associated with muscle atrophy. These facts suggest that the signaling associated with diaphragm atrophy during MV may involve different mechanisms compared with other models of muscle atrophy. Diaphragm appeared to be more susceptible to MV.

Objective To investigate the value of virtual touch tissue imaging (VTI) in the differential diagnosis of small solid thyroid nodules.Methods 35 patients with 41 small thyroid nodules were examined by conventional ultrasound and VTI examination.The stiffness of the nodules in VTI images was scored.Area ratios of VTI and gray scale images of nodules were calculated.The pathological diagnosis was used as the gold standard.The ROC curve was drawn to determine the cut off point of area ratio to predict thyroid cancer.Results 41 small thyroid nodules were confirmed by pathological diagnosis,including 23 benign and 18 malignant nodules.Compared with benign nodules,the ratio of VTI hardness score ≥4 was significantly higher in the malignant nodules (88.9％ vs 8.7％,P ＜0.01).Compared with benign nodules,the area ratios of malignant nodules were higher (1.67 ± 0.16 vs 1.23 ± 0.12,P ＜0.01).When 1.46 was set as the cut off point of areas ratio,the sensitivity and specificity of diagnosing thyroid cancer were 88.9％ and 95.7％,respectively.Conclusions VTI can provide information about thyroid nodules hardness.It has high value in the differential diagnosis of small solid thyroid nodules.
