1.INFLUENCES OF CONDITIONING STIMULI OF PERIPHERAL NERVE ON C-FIBRE AFFERENT TERMINAL EXCITABILITY IN SPINAL TOADS
Journal of Xi'an Jiaotong University(Medical Sciences) 1982;0(04):-
The antidromic C waves elicited by stimulating the entry zone of the dorsal root were recorded in spinal toads. Influences if conditioning stimuli in 60 T from sciatic nerve on antidromic C waves were observed. The conditioning stimuli produced marked increace in the excitability of the C-afferent terminals. The increased excitability possessed two phases. The results indicat that periphiral primary afferent A and C-fibres can produce presynaptic inhibition in C-fibre terminals.

Basic & Clinical Medicine 2006;0(09):-
Objective To establish and optimize the method of isolation and cultivation of rat bone marrow mesenchymal stem cells(MSCs),and to investigate the condition and capability of hepatic differentiation of MSCs.(Methods) Rat bone marrow cells were collected from rats of 5~6 week and mononeuclear cells were isolated by Percoll density gradient centrifugation.MSCs were cultivated and purified by adherence method.Morphology,RT-PCR and immunocytochemistry were used to identify the role of substrates,the kinds of the cytokines and concentrations of cytokines on the hepatic differentiation potential.Results The quality and quantity of the isolated bone marrow mononuclear cells reached the peak by using 57% Percoll density gradient centrifugation.Discarding the suspending cells after 24h incubation and subculturing the cells with low seeding density were helpful for acquiring MSCs with improved reproductive capability and active function.MSCs could be successfully induced under HGF/FGF-4 induction on the substrate of(10 ?g/mL) fibronectin.MSCs exhibited round in shape after differentiation,instead of fibroblast-like morphology before.Albumin mRNA and protein were positively expressed in MSCs,withoutdetection of alpha-fetoprotein(AFP).Conclusion The optimization of rats' age,the density of Percoll,the methods of cell cultivation are conducing to obtaining a pure population of MSCs with good differential activity.MSCs are inclined to differentiate into mature hepatocyte-like cells under the induction of HGF/FGF-4.
3.Application advances in cellular immunotherapy for acute leukemia
Journal of Leukemia & Lymphoma 2012;21(4):249-251
Acute leukemia is the most common hematological malignancies.Based on the development of chemotherapy drugs and the improvement of chemotherapy regimens,the remission rate after induction chemotherapy increases obviously.But leukemia patients can not live for a long time mainly because of the ease relapse,so how to extend remission after treatment become the key to solve the problem.People are paying more and more attention on the cellular immunotherapy since it playes major roles in eradicating minimal residual disease of leukemia,reducing leukemia relapse and improving leukemia patients overall survival.This article reviews the application advances in research on this subject.

Methods:The relationship of the Dictionary of Occupation and the career development of medical represent-atives was discussed, and then the influence of including the dictionary on medical representatives was analyzed. Results and Conclu-sion:The Dictionary of Occupation puts forward higher requests to the code of conduct, professional ability and professional ethics of medical representatives, which plays important roles in the career development of medical representatives. And as a professional stand-ard with clear definition and description, the Dictionary of Occupation also leads to the direction of sustainable and healthy development of medical representatives.
5.Therapeutic Observation of Moxibustion plus Cang Gui Tan Xue Needling Method for Cervical Spondylosis of Nerve Root Type
Shanghai Journal of Acupuncture and Moxibustion 2015;(7):660-662
Objective To observe the clinical efficacy of moxibustion plus Cang Gui Tan Xue (dark turtle seeking hole) needling method in treating cervical spondylosis of nerve root type. Method Sixty patients with cervical spondylosis of nerve root type were randomized into a treatment group and a control group, 30 in each group. The treatment group was intervened by moxibustion plus Cang Gui Tan Xue needling method, and the control group was by simple needling method. The symptom and sign score was observed before and after 2-course treatment, and the clinical efficacy was compared. Result The total effective rate was 90.0%in the treatment group versus 83.3%in the control group, and the difference was statistically significant (P<0.05). After intervention, the symptom and sign scores were significantly changed in both groups (P<0.05). There was a significant difference in comparing the symptom and sign score between the two groups after intervention (P<0.05). Conclusion Moxibustion plus Cang Gui Tan Xue needling method is effective in treating cervical spondylosis of nerve root type.
6.Focus on fecal microbiota transplantation in children
Chinese Journal of Applied Clinical Pediatrics 2017;32(7):481-483
Fecal microbiota transplantation(FMT)is a method to recover the gut microbiota and treat the intestinal or non-intestinal diseases through transplanting the fecal liquid from healthy population into patients' gastrointestinal tract.There are limited data about the FMT in children.The clinical practice needs professional workgroups,strict indications,normalized and precise procedures.

32 cases of insomniacs were treated by using EMG biofeedback. The total efficierky was 84.4%. The result indicated that the curative effect of the therapy was satisfactory. Furthermore this paper mentioned the advantages of the therapy and points for attention. Also the principle of the treatment was discussed.

Single unit activity were recorded from 157 dorsal horn neurons in the spinal rats by stimulation of left surat nerves. Stretching urinary bladder were performed after the neurons were identified by somatic afferents. 32 out of the 157 could also be activated by stretching urinary bladders. These recorded dorsal horn neurons which responded to both somatic and visceral inputs are called somatovisceral convergent neurons (SVCN). The afferent visceral fibers were N group according to conductive velocity in our experiment. It has been shown that C-fiber component in 9 WDR neurons were incresed by stimulating the left sural nerves after stretching urinary bladders. 15 spontaneous- discharge WDR neurons were recorded and 13 out of them were excited, meanwhile, 2 out of them were inhibited after urinary bladders were stretched. The study provides the new data for the convergence from the somatic and visceral afferents in the dorsal horn of spinal cord and supplies the first evidence for central mecha nism of visceral referred pain.

Objective To study the effect of cognitive treatment on the compliance for medication and recrudescence of patients with schizophrenia.Method 106 schizophrenic patients were randomly allocated to the study and the control; both groups treated with antipsychotic medical treatment and health education, while the study group also accepted cognitive psychotherapy. Before treatment and at the ends of 0, 6, 12 months of treatment, the efficacy were investigated using the Brief Psychiatric Rating Scale (BPRS), Insight and Treatment Attitude Questionnaire (ITAQ) and Self-designed Compliance Survey in order to assess the compliance and the recrudescence. Results All the indexes after cognitive psychotherapy were significantly better than those before cognitive psychotherapy. Conclusion The cognitive psychotherapy can effectively reinforce the compliance of patients with schizophrenia, and then improve the quality of life for them.

Objective To study the protective effect and molecular mechanism of trypsin inhibitor on reperfusion injury after cerebral ischemia. Methods The model of ischemia for 1h and repufusion for 24h of rat cerebrum was set by ligating MCAO described by zea-longa. 24 male rats were divided randomly into the sham operation group, the control group and trypsin inhibitor group. The presence of neurological function deficit was measured by Zea-Longa method, and the immunohistochemical staining and TUNEL were used to detect p53 protein expression and cell apoptosis in the brain tissues respectively. Results The score of neurological function deficit was zero in the sham operation group, 2 8?1 0 in the control group and 1 3?0 7 in trypsin inhibitor group. There were 12 3?2 5 p53 immunostaining positive cells in the control group and 5 5?1 3 in trypsin inhibitor group. The number of apoptotic cells was zero in the sham operation group, 7 6?1 0 in the control group, and 3 5?0 9 in trypsin inhibitor group. There was a significant difference in all above observing indices between the control group and trypsin inhibitor group(P
