Objective To compare the effects between bloodletting at auricular points and acupuncture at specific points [Yintang (GV 29) or Yanglao (SI 6)] for analgesia in acute lumbar sprain.Method Totally 100 patients with acute lumbar sprain were randomized into a treatment group and a control group, 50 cases in each group. The treatment group was intervened by bloodletting at auricular points, while the control group was by acupuncture at specific points [Yintang (GV 29) or Yanglao (SI 6). The Present Pain Intensity (PPI) from the Short-form McGill Pain Questionnaire was taken as the observation index. The changes of PPI were compared respectively 10 min and 30 min after treatment.Result The PPI scores were significantly changed 30 min after treatment in both groups (P<0.05). The PPI scores in the treatment group were significantly different from that in the control group both 10 min and 30 min after intervention (P<0.05).Conclusion Bloodletting at auricular points and acupuncture at specific points are both effective in releasing pain in acute lumbar sprain, while bloodletting at auricular points can produce a more significant real-time analgesic effect.

AIM: To investigate the effect of L-arginine (L-Arg) on intimal proliferation and expression of related cell cycle regulatory factors after vascular injury in rats. METHODS: Rats were divided into three groups :sham operation group, balloon injury group(this group included balloon 48 h,7 d and 14 d subgroup) and balloon+L-Arg group. Neointima area were calculated morphologiocally. The expression of cyclin dependent kinase-2(CDK2),cyclin E and proliferation cell nuclear antigen (PCNA) were measured by means of immunohistochemical technique and computer image analyzer. RESULTS: After vascular balloon injury, the level of plasma NO decreased, CDK2、cyclin E and PCNA expressed in the media at 48 h and in the neointima at 7 d and 14 d but with low and undetected expression in the media, the expression of CDK2, cyclin E and PCNA increased with the intima thickening. Compared with balloon 14 d group, the plasma NO level increased (P＜0.01）, the neointima area reduced by 59.1%(P＜0.01) and the positive expression indexes of CDK2, cyclin E and PCNA decreased by 36.1%, 46.3% and 76.2% respectively in balloon+L-Arg group (P all＜0.01）. CONCLUSION: L-Arg can effectively repress intima proliferation after vascular injury, which may be associated with its inhibiting the proliferation of vascular smooth muscle cell through downregulating the excessive expression of CDK2, cyclin E and PCNA.

The medial temporal lobe epilepsy with hippocampal sclerosis is one of the most common drug resistant epilepsy,which involves complex neural networks and often requires surgical treatment.Studies have shown that it is related to the history of febrile convulsions,however,the further research is needed.Therefore,it is particularly important to accurately identify hippocampal sclerosis and guide clinical treatment.In this paper,the classification of hippocampal sclerosis was summarized,and the possible mechanism of hippocampal sclerosis was explored in terms of cationic-chloride co-transporters,glutamate and its receptors,and changes in expression of mRNA.The characteristics of magnetic resonance,magnetic resonance spectroscopy and PET of hippocampal sclerosis were listed to provide evidence for early recognition of hippocampal sclerosis.In theory,it provides ideas for further prevention of hippocampal sclerosis and improvement of quality of life in patients with medial temporal lobe epilepsy and hippocampal sclerosis.

Objective To observe the efficacy and safety of rituximab in the treatment of systemic sclerosis (SSc).Methods This was a prospective,non-randomized controlled trial.All patients with SSc were hospitalized from January 2011 to August 2015.Fifty-two patients were enrolled,including 15 patients in the intervention group and 37 patients in the control group.Both groups were given cyclophos-phamide and prednisone.The intervention group was also given rituximab 375 mg/m2,once every 4 weeks,a total of 4 treatments.The erythrocyte sedimentation rate (ESR),C-reactive protein (CRP),intedeukin 6 (IL-6),modified Rodnan skin score (mRSS),HRCT,forced vital capacity (FVC％),1％ forced expiratory volume percentage (FEV 1％),percentage of carbon monoxide dispersion percentage (DLCO％) were assessed alternatively before treatment,6 months and 12 months after treatment.The repeated measures analysis of variance and t-test were used for statistical analysis.Results Both groups showed improvement in ESR,CRP,IL-6,mRSS,HRCT,FVC％,FEV1％ and DLCO％ (P＜0.05),but ESR [6 month after treatment (33±9) mm/1 h,12 month after treatment (20±4) mm/1 h],CRP [6 month after treatment (12.7±3.4) mg/L,12 months after treatment (12.7± 3.4) mg/L],IL-6 [6 month after treatment (73±10) pg/ml,12 month after treatment (57±11) pg/ml],mRSS [6 months after treatment (22.2±1.3),12 month after treatment (18.4±3.1)],HRCT score [6 month after treatment (11.9±1.4),12 month after treatment (11.3±1.0)],in patients of the intervention group were decreased more significantly than patients of the control group (P＜0.05),and FVC％ [6 month after treatment (69.0± 3.4)％,12 month after treatment (77.2±4.1)％],FEV1％[6 month after treatment (73.3±3.4)％,12 month after treatment (78.4±1.6)％] and DLCO％ [6 month after treatment (60.6±2.7)％,12 month after treatment (70.7± 3.0)％] were increased more significantly than patients of the control group (P＜0.05).It showed that the efficacy of the intervention group was better than the control group.There was no infusion reactions,infection,hepatitis B virus reactivation and other side effects in the treatment were observed.Conclusion Rituximab can reduce the level of inflammation in patients with SSc and improve skin sclerosis and lung function.Rituximab combined cyclophosphamide is expected to be a new,safe and effective treatment of SSc.
