Objective Estimating the therapeutic effect of music therapy and speech language therapy on post-stroke patients with non-fluent aphasia.Methods Eighty-four post-stroke patients diagnosed with non-fluent aphasia who came from the First Affiliated Hospital of Medical College of Shihezi University were collected between June 2012 and May 2014,then they were randomly divided into music therapy group (n =42) and speech language therapy group (n =42;including chronic (n =46) and acute groups (n =38)) based on table of random numbers.On the basis of conventionally using neurological drugs,music therapy and speech language therapy were given to the patients for one month,respectively.And language function was assessed by partial items of Chinese Version-Western Aphasia Battery before and after therapy.Results No significant changes were found in spontaneous speech,comprehension,repetition,naming and aphasia quotient in chronic and acute group patients through the music therapy and speech language therapy.Significant improvements were revealed in repetition (32.00 (15.00,53.75) vs 48.50(24.50,72.00),Z =2.147,P =0.032;33.00(14.50,49.25) vs 48.50(18.50,63.75),Z =2.018,P=0.038),naming (20.00 (8.50,34.75) vs 37.5(12.50,64.75),Z =2.298,P =0.022;19.50 (7.00,31.25) vs 34.50 (15.00,52.75),Z =2.039,P =0.041) and aphasia quotient (24.50 (10.50,37.50) vs 43.00 (18.00,64.75),Z =2.432,P =0.015;22.50 (10.00,34.50) vs 36.00 (14.00,54.00),Z =2.027,P =0.043) through music therapy and speech language therapy in chronic group patients.Comprehension was significantly improved through music therapy in chronic group patients.Repetition (24.50 (11.00,38.75) vs 46.50 (24.50,67.75),Z =2.038,P =0.043;26.50 (9.50,36.25) vs 42.50(19.00,64.25),Z =1.972,P =0.048) was significantly improved through music therapy and speech language therapy in acute group patients.And spontaneous speech (2.00 (1.00,3.75) vs 8.00 (4.00,12.75),Z =2.012,P =0.036),comprehension (51.00 (17.50,73.75) vs 85.00 (48.00,101.00),Z =2.298,P =0.022),naming (17.50(6.00,29.00) vs 37.50(16.00,58.75),Z =2.161,P =0.031) and aphasia quotient (18.00 (7.50,31.25) vs 42.50 (20.50,63.75),Z =2.256,P =0.024) were significantly improved through music therapy in acute group patients.However,no significant improvements were found in the speech language therapy group of acute patients.Conclusion The two therapies are effective in the chronic patients with non-fluent aphasia,and music therapy is also effective in acute patients with non-fluent aphasia.

Objective To investigate expression and role of protease catenin-1(PN-1), thrombin(thrombin), protease activated receptor-1(PAR-1) in rats brain edema tissue after intracerebral hemorrhage(ICH).Methods Adult male SD rats 80 were randomly divided into sham group,ICH group after number, 40 in each group, ICH group autologous arterial method of making a rat model of experimental ICH in the right caudate nucleus unit injection.The degree of neurological dysfunction between 2 groups was evaluated at 12 h,24 h and 120 h after post-operation.Observed the morphology of brain cells by HE staining.Changes of PN-1,thrombin, PAR-1 index in rat brain tissue at 3,6,10,12,24,48 and 120 h were detected by Western blot.Results Neurological dysfunction score ICH rats after modeling 12,48,120 h were significantly lower than the sham group(P<0.05);ICH in rats after modeling 3,6,10,12,24,48 and 120 h of brain tissue PN-1, thrombin, PAR-1 compared with sham-operated group were significantly increased (P<0.05); ICH rat brain tissue PN-1, thrombin, PAR-1 appeared in 12 h after modeling shwed a gradual downward trend (P<0.05). Conclusion ICH hematoma surrounding brain tissue in rats PN-1 has the effect of inhibiting thrombin and PAR-1 overexpression, cause nerve damage.

Cerebral hyperperfusion syndrome (CHS) is one of the complications after stenting in patients with carotid stenosis.Although its incidence is lower,it may result in serious disability or death in patients.Full awareness and understanding of CHS and its related risk factors may contribute to its prevention and treatment.

OBJECTIVE:To study the effects of Buyang huanwu decoction on the contents of CD40 and CD40L in the serum of rats with cerebral ischemia. METHODS:Rats were randomized into a sham-operation(normal saline)group,a model(normal saline)group,a positive control [6.75 mg/(kg·d)clopidogrel hydrogen sulfate] group and Buyang huanwu decoction high-dose and low-dose [26 and 6.5 g/(kg·d)] groups,with 20 rats in each group. Suture occlusion of middle cerebral artery was used to establish the rat models of focal cerebral ischemia,which were given drugs ig on the 2nd day after the operation and for 14 consecutive days. Then pathological changes in the cerebral tissues of all groups of rats were observed and the contents of CD40 and CD40L in the serum thereof were detected by euzyme-linked immunosorbent assay. RESULTS:The rats in the model group demonstrated isch-emia-like pathological change in the cerebral tissue on the side of lesion. The ischemia-like cerebral tissue on the side of lesion in the positive control group and Buyang huanwu decoction high-dose group were improved compared to the model group. The patho-logical change in the cerebral tissue on the side of lesion in Buyang huanwu decoction low-dose group was similar to that in the model group. The contents of CD40 and CD40L in the serum of rats in the model group were higher than in the sham-operation group. The content of CD40L in the serum of rats in positive control group and Buyang huanwu decoction high-dose group were lower than the model group. There were statistical differences(P<0.01 or P<0.05). Except as described above,no other statistical-ly significant differences (P>0.05) were noted. CONCLUSIONS:Buyang huanwu decoction can improve brain cell morphology and reduce cerebral ischemic tissue injury in model rat with cerebral ischemia by a mechanism which may be related to decreasing the content of CD40L.

During coronavirus disease 2019 epidemic, the treatment of severe trauma has been impacted. The Consensus on emergency surgery and infection prevention and control for severe trauma patients with 2019 novel corona virus pneumonia was published online on February 12, 2020, providing a strong guidance for the emergency treatment of severe trauma and the self-protection of medical staffs in the early stage of the epidemic. With the Joint Prevention and Control Mechanism of the State Council renaming "novel coronavirus pneumonia" to "novel coronavirus infection" and the infection being managed with measures against class B infectious diseases since January 8, 2023, the consensus published in 2020 is no longer applicable to the emergency treatment of severe trauma in the new stage of epidemic prevention and control. In this context, led by the Chinese Traumatology Association, Chinese Trauma Surgeon Association, Trauma Medicine Branch of Chinese International Exchange and Promotive Association for Medical and Health Care, and Editorial Board of Chinese Journal of Traumatology, the Chinese expert consensus on emergency surgery for severe trauma and infection prevention during coronavirus disease 2019 epidemic ( version 2023) is formulated to ensure the effectiveness and safety in the treatment of severe trauma in the new stage. Based on the policy of the Joint Prevention and Control Mechanism of the State Council and by using evidence-based medical evidence as well as Delphi expert consultation and voting, 16 recommendations are put forward from the four aspects of the related definitions, infection prevention, preoperative assessment and preparation, emergency operation and postoperative management, hoping to provide a reference for severe trauma care in the new stage of the epidemic prevention and control.
