Objective To investigate the occupational burnout status of rehabilitation therapists in medical institutions and analyze relat-ed factors. Methods From December, 2015 to February, 2016, a total of 264 rehabilitation therapists, selected with random cluster sampling method, were investigated with Maslach Burnout Inventory-General Survey (MBI-GS) in Bengbu, China. Results The detection rate of ther-apist burnout was 81.1%, and the average score was (3.13±1.07). There were significant differences in the score of occupational burnout and its three dimensions (P<0.05), except emotional exhaustion dimension among different ages (P>0.05). Multiple regression analysis showed that the gender, age, marital status, educational background, professional title, shift work, job demand, job autonomy, social support, de-mand-autonomy ratio and income levels were the factors related with occupational burnout. Conclusion Rehabilitation therapists generally feel occupational burnout. It is different with demographic characteristics and working conditions.

Objective To explore basic regularities in sinew lesion distribution in patients with knee osteoarthritis. Method Two hundred and thirty knee osteoarthritis patients with 253 affected knees were selected. Under the sinew theory, the positions and frequency of sinew foci around the knee joint were counted by palpation. Result In the distribution of foci, the total frequency accounted for 39.1% in the Foot-Yangming. Of them, the single Foot-Yangming sinew type accounted for 23.3% and the complex type accounted for 48.5%. The total frequency accounted for 32.4% in the Foot-Taiyang. Of them, the single Foot-Taiyang sinew type accounted for 21.3%, the complex type accounted for 44.5%. The Foot-Yangming + Foot-Taiyang sinew lesions accounted for 14.6% and the single foot-three-yin sinew type accounted for 15.0%. Conclusion Knee osteoarthritis of Foot-Yangming or Foot-Taiyang sinew type should be treated from “sinew”.

Objective To establish the oxygen glucose deprivation (OGD)/reoxygenation experimental model of hippocatnpal neurons of rat in vitro, and to try to identify the length of time for producing optimum injury in this model. Method The primary hippocampal neurons of newborn Sprague-Dawley rats were cultured for 7 days and randomly (random number) divided into a control group and OGD groups. The OGD groups were assigned into 1 h, 2 h, 4 h, 6h, 8 h and 10 h subgroups in accordance with different lengths of time for oxygen glucose deprivation. The neurons of OGD groups were placed into a tri-gas incubator containing 0.5% oxygen and the culture medium was substituted with the glucose-free Earle' s balanced salt solution, simulating cerebral ischemia injury in vivo. The morphology of neurons was observed after reoxygenation for 24 hours. The MIT assay was used to determine the rate of survived cells derived from the value of optical density (OD) of cells. The lactate dehydro-genase (LDH) content in culture medium was detected to evaluate the neuron injury. The apoptotic rate of neurons was measured by using flow cytometry. Dunnett-test and Spearman correlation analysis were used to analyze the data with SPSS version 16.0 soft ware package. Results The morphological damage of neurons in OGD groups aggravated gradually, optical density and cell survival rate decreased (rs= -0.961 and rs = -0.966, P <0.01), and the amount of LDH increased (rs = 0.990, P <0.01) with longer duration of exposure to oxygen glucose deprivation, and the rate of neuron apoptosis increased obviously which was significantly statistical difference in com-parison with the control group (P < 0.05). Under the setting of oxygen glucose deprivation for 6 hours, the apop-tosis rate of neurons approximated to 50% . Conclusions The oxygen glucose deprivation/reoxygenation model of rat's hippocampal neurons in vitro was established successfully. From the findings of morphological changes and apoptosis rate of neurons, the oxygen glucose deprivation for 6 hours may be the suitable length of time for inducing neuron injury in this model.

Objective To investigate the safety, feasibility and results of laparoscopic assisted distal radical gastrectomy for gastric cancer. Methods Twenty-three cases of gastric cancer were subjected to laparoscopic assisted distal radical gastrectomy, D_(1+α)/D_(1+β) lymphadenectomy on 3 cases and D_2 lymphadenectomy on 20 cases. All cases received Billroth I reconstruction. Results Laparoscopic assisted distal radical gastrectomy was carried out in all cases successfully. The mean operative time was (205 ±38 )min, mean blood loss was (105 ± 66) ml and mean number of lymph nodes dissected was 19.7 ± 6.2 each case. The mean postoperative time of recovery of bowel function was (3.5 ±1.2) d,mean postoperative time of liquid intake was (4.9 ±0.9) d and mean hospitalization was (10.2 ± 2.7) d. No postoperative death or anastomotic fistula was found. Postoperative upper gastrointestinal bleeding occurred in 1 case and was cured by conservative treatment. Follow-up for 1-12 months revealed no recurrence or metastasis. Conclusions Laparoscopic assisted distal radical gastrectomy is a safe and feasible procedure with satisfactory short-term outcomes.Moreover,the short-term outcomes may be improved if the patients are treated under the notion of fast track surgery.

Objective To study the establishment of rat model of asphyxia-cardiac arrest and efficacy of CPR in order to find the length of optimum time of asphyxia to cause injury.Methods One hundred and twenty-six male Sprague-Dawley rats were randomly (random number) divided into sham operation group and experimental groups.Cardiac arrest was induced by asphyxiation after intravenous injection of vecuronium bromide.The experimental groups were assigned into AP4 (four-minute asphyxia period),AP6 and AP8 subgroups in accordance with different lengths of time of asphyxia subjected to.In these groups,CPR,including pre-cordial compression and synchronized mechanical ventilation,was initiated 4,6 and 8 min after asphyxia-induced cardiac arrest,respectively.The successful ratio of resuscitation and hemodynamic variables were recorded.Brain water content,neural deficit scores (NDS),imaging changes on MR,pathological changes of brain tissue and neuronal apoptosis were evaluated at 1 d,3 d and 7 days after ROSC.All the data were analyzed by single-factor analysis of variance or Chi-square test.P ＜ 0.05 was considered statistically significant.Result The lowest NDS occurred at 1 d after ROSC,brain water content and imaging changes on MR were most obvious at 3 d after ROSC,while pathological changes of brain tissue and neuronal apoptosis increased and reached the peak at 7d after ROSC.The survival rates after 24 hours of AP4,AP6 and AP8 groups were 85％,75％ and 45％,respectively.The rate of ROSC and survival rate of AP8 group were significantly lower than those of other groups (P ＜0.01).The longer time of asphyxia the severer pathological changes of brain tissue,brain edema,neural deficit,and magnetic resonance imaging changes in all experimental groups.As compared to other groups,the brain damage index of AP8 group was most serious,while that of AP6 group was moderate.Conclusions The rat model following asphyxia-induced cardiac arrest and cardiopulmonary resuscitation was established successfully.From the evidence of survival rate and damage grade of brain tissue,asphyxia for 6 min may be the rational length of ischemic time in this model.

Non-coding RNA (ncRNA) is a type of RNA that has no or limited protein-coding ability. It mainly includes microRNA (miRNA), long non-coding RNA (lncRNA), circular RNA (circRNA), transfer RNA (tRNA), PIWI-interacting RNA (piRNA), and small nucleolar RNA (snoRNA).At present, research has found that ncRNA plays a central role in regulating the function of pancreatic β cells, and that defects of insulin signaling is an important cause of diabetes.This article reviews the relationship between ncRNA and insulin signaling pathway in recent years, and discusses the possibility of ncRNA as a potential therapeutic target and clinical diagnostic marker for diabetes, hoping to provide some reference for the treatment and diagnosis of diabetes.
