Objective To investigate the effects of creatine supplement on contractile properties of soleus (SOL) and extensor digitorum longus (EDL) in elder rat. Methods 20 male Sprague-Dawley rats were randomly divided into control group and creatine supplement group with 10 rats in each group. After 6 weeks, the content of creatine and phosphocreatine were detected by high performance liquid chromatography,and contractile properties were examined in SOL and EDL in vitro at 30 ℃. Results The content of creatine and phosphocreatine both in SOL and EDL were higher in the creatine supplement group than in the control group (P<0.05). In SOL, creatine supplements increased the maximum twitch tension (Pt), maximum titanic tension(P0), decreased time to maximum twitch tension (TPT), but only time from maximum twitch to half relaxation (TPR50) significantly decreased, compared with the control group. In EDL, creatine supplements significantly increased Pt, P0 and decreased TPT (P<0.05). But there was no significant difference in TPR50 between 2 groups (P>0.05). Creatine supplements significantly increased the fatigue resistance of the SOL and there was no significant effect on EDL. The force potentiation which occurred in EDL during the initial 20~30 s of the fatigue test significantly increased (P<0.05). Conclusion Creatine supplement is effective on the contractile properties of SOL and EDL in elder rats, but the effect is dependent on the fiber types.

OBJECTIVETo provide suggestion for MDAEs monitoring with analyzing the features of the 1028 reports of MDAEs.

METHODSWith retrospective case study, this paper analyzed 1 028 MDAE reports in Guiyang during 2012.

RESULTSThe intrauterine device (IUD) caused the higher proportion of adverse events with serious degree. Monitoring consciousness of grassroots users needs to be improved. The quality of the reports should be enhanced.

CONCLUSIONSMore attention should be paid to monitoring on IUD. The level of MDAEs monitoring should be improved through carrying out targeted training and publicity, establishing and improving MDAEs monitoring network.

Extramedullary plasmacytoma (EMP) is a rare tumor characterized by proliferation of monoclonal plasma cells,often occurs in the head and neck,followed by gastrointestinal and skin.Diagnosis is based on biopsy,which is the only accurate and reliable method.EMP is needed to discriminate with similar diseases.Radiotherapy is the preferred treatment method of EMP,because it has a higher radiation sensitivity.Sometime we can choose comprehensive treatment because of illness need.Hematopoietic stem cell transplantation is not as the preferred treatment option because of transplant rejection.

Low-dose chemotherapy is concerned in treating malignant tumor in recent years.The lowdose,metronomic chemotherapy is not only effective in antiangiogenic,but also avoid chemotherapy side effects,such as suppression of bone marrow,dysfunction of liver and kidney,gastrointestinal reaction and drug resistance.Thereby it can increase patient compliance,improve life quality and prolong survival time.Currently chemotherapy in neuroblastoma still plays a key role,especially low-dose chemotherapy,which can protect self-immune function and reduce the physical injury in children.

Objective To observe the clinical efficacy of acupuncture plus rehabilitation training in improving post-stroke dysphagia. Method A total of 60 patients with post-stroke dysphagia were randomized into a treatment group and a control group, 30 cases in each group. The two groups were intervened by basic treatment of internal medicine and swallowing rehabilitation training, and the treatment group was additionally given acupuncture treatment. The Standardized Swallowing Assessment (SSA), water swallowing test and Swallowing Quality of Life Questionnaire (SWAL-QOL) were evaluated in the two groups before and after the treatment. Result After the treatment, the SSA scores in the two groups were significantly decreased compared to those before the treatment (P<0.01), and the SWAL-QOL scores were significantly increased compared to those before the treatment (P<0.01); the SSA score in the treatment group was significantly lower than that in the control group (P<0.01), and the SWAL-QOL score was significantly higher than that in the control group (P<0.05). The water swallowing test classification after the treatment was significantly superior to that before the treatment in the treatment group (P<0.01), and there was a significant difference compared to that in the control group (P<0.05). Conclusion Acupuncture plus rehabilitation training can obviously improve the swallowing function of patients with post-stroke dysphagia, and the clinical efficacy was superior to single rehabilitation training.

Objective To explore the application of the comprehensive pain assessment scale to the treatment of postherpetic neuralgia (PHN). Methods About 100 patients suffering from PHN were randomly divided into two groups: the control group and experiment group. The former was treated with recording for pain assessment and the latter was treated with the comprehensive pain assessment scale. Two sets of data were compared and analyzed in view of quality of sleep, average length of hospitalization and the duration of side effects of drugs. Result The effect of the experiment group was better than the control group in the quality of sleep, the average length of hospitalization, reduction of side effect duration of drugs (P<0.05). Conclusion The comprehensive pain assessment scale throughout the whole process of the PHN treatment can achieve timely and effective assessment of pain and reduce the side effect duration of drugs, improve their sleep quality, and shorten the hospital stay.
