RESUMO
Sarcopenia has attracted increasing attention with the study of nutrition in patients with liver disease. Sarcopenia is an independent risk factor for a poor prognosis of liver disease and is becoming increasingly common in patients with liver disease. Studies have shown that patients with liver disease and sarcopenic obesity have a worse prognosis than patients with liver disease and simple sarcopenia or obesity. In clinical practice, it is easy to recognize patients with malnutrition and decreased muscle mass, but we often ignore those patients with normal body weight or even obesity who will likewise experience muscle mass loss. Simply relying on the monitoring of body mass and body mass index to assess the nutritional and muscle status of patients with liver disease is not accurate. At present, our understanding of the relationship between chronic liver disease and sarcopenic obesity is still poorly understood. In this paper, the research progress on chronic liver disease, sarcopenia, and sarcopenic obesity in recent years is reviewed so as to provide a theoretical basis for improving the clinical prognosis of patients with liver disease.

Objectives:To investigate the effect of acupoint catgut embedding on motor function of rats with cerebral ischemia-reperfusion, and explore its possible mechanism. Methods:A total of 48 three-month old healthy specified pathogen free male Sprague-Dawley rats were randomly divided into three groups with 16 rats in each group. The right external carotid artery was severed only in sham operation group. Right middle cerebral artery occlusion was induced for 90 minutes under isoflurane anesthesia using a monofilament in model group and acupoint catgut embedding group. Ninety minutes after reperfusion, the acupoint catgut embedding group accepted acupoint catgut embedding on Baihui (DU20) acupoint and anterior oblique line of vertex-temporal. After one, three, seven and 14 days of reperfusion, they were assessed with Neurological Evaluation and Screen Prehensile Test. After 14 days of reperfusion, the infarct volume was measured with TTC staining; the expression of glial fibrillary acidic protein (GFAP) and Synapsin I was detected with immunohistochemistry, Western blotting and reverse transcription real-time quantitative polymerase chain reaction (RT-qPCR). Results:Compared with the sham operation group, the neurological score significantly decreased (t > 11.851, P < 0.001), the prehensile time significantly decreased (t > 6.190, P < 0.001), the expression of GFAP increased (P < 0.05), and the expression of Synapsin I decreased (P < 0.05) in the model group. Compared with the model group, the neurological score significantly increased (t > 3.464, P < 0.001), the prehensile time significantly increased (t > 3.642, P < 0.001), the cerebral infarction volume significantly decreased (F = 93.426, P < 0.001), the expression of GFAP decreased (P < 0.05), and the expression of Synapsin I increased (P < 0.05) in the acupoint catgut embedding group. Conclusion:Acupoint catgut embedding could promote the recovery of motor function of rats with cerebral ischemia-reperfusion injury, which may be related with inhibiting the proliferation of astrocytes, increasing the regeneration of axons in the ischemic penumbra and enhancing synaptic connection.
RESUMO
<p><b>OBJECTIVE</b>To establish an improved method for stereotactic location of the supraoptic nucleus in rats.</p><p><b>METHODS</b>Twenty-four SD rats were randomly divided into experimental group (12 rats) and control group (12 rats) for oblique (20° to the left) stereotactic puncture (OSP group) and vertical stereotactic puncture (VSP group), respectively, both targeting the supraoptic nucleus (SON). The surgical data and postoperative (within 24) mortality of the rats were compared between the two groups.</p><p><b>RESULTS</b>The nucleus locating time was longer in OSP group than in VSP group (59.55∓3.64s vs 27.44∓2.18 s, P=0.000), and the postoperative mortality rate of the rats did not differ significantly between the groups (0 vs 44.4%, P=0.082). In OSP group, compared with VSP group, the procedure was associated with a lowered rupture rate of the superior sagittal sinus (11.1% vs 88.9%, P=0.003), a shortened hemostatic time after craniotomy (52.89∓24.05 s vs 157.445 ime a s, P=0.000) and after puncture (24.33 reas 45 s vs 133.89∓28.81 s, P=0.000), and also a shortened operation time (178.89 on tims vs 362.44 timees, P=0.000).</p><p><b>CONCLUSION</b>The improved method for locating supraoptic nucleus in rats is convenient, stable and reproducible, and helps to avoid important blood vessels and specific nuclei according to the needs of different experiments and allows the operators to choose different surgical paths.</p>
