Objective To observe the clinical effect of different doses of simethicone on the colonoscopy bowel preparation.Methods One hundred and fifty outpatients who received colonoscopy were randomly divided into three groups:group A1 (PEG plus 5 ml simethicone),group A2 (PEG plus 10 ml simethicone) and group B (PEG =polyethylene glycol electrolyte).The colonic cleaness,effect of removing bubbles,total procedure time,patients' satisfaction and tolerance were observed during the examination.Results The satisfaction with bubbles removal were 98.0% (49/50),100.0% (50/50) and 80.0% (40/50) with significant difference(x2 =17.855,P =0.000).However,there was no difference in cleaness (x2 =1.500,P =0.472),total procedure time (Z =-0.333,P =0.765),patients' satisfaction (x2 =6.303,P =0.178) and tolerance (x2 =8.238,P =0.083).Conclusion Simethicone is of benefit for colonoscopic bowel preparation in removing air bubbles,which can enhance visibility.Five ml dose of simethicone can meet the basic need of removing air bubbles,and 10 ml dose of simethicone can exert better effects.
2.Directed forgetting effect to disease/death-related words in elder people
Chinese Mental Health Journal 2017;31(6):480-484
Objective:To explore the directed forgetting ability of elder people to disease/death-related words under the conditions of the neutral and negative emotion.Methods:Thirty-six elder people and thirty-seven young people were included in this study.The directed forgetting effects to disease/death-related words were compared by using item-method directed forgetting paradigm under the neutral and negative emotional conditions.Results:Under the neutral and negative emotion conditions,higher recognition of to-be-remembered (TBR) than to-be-forgotten (TBF) words in elder group and younger group (Ps < 0.05).The elder group showed the weaker effect of directed forgetting than younger group[neutral emotion:(0.4 ± 0.1) vs.(0.6 ± 0.1);negative emotion:(0.3 ± 0.1) vs.(0.7 ± 0.04),Ps < 0.05].Under the negative emotion condition,elder people showed stronger effect of directed forgetting for sensitive words compared with control words[(0.4 ± 0.1) vs.(0.1 ± 0.1),P < 0.001].Conclusion:The results suggest that the directed forgetting ability of elderly is weaker than that of young individuals,the ability of non-sensitive words than that with sensitive words,and the directed forgetting effect of elder people tonon-sensitive words in negative emotion is weaker than that in neutral emotion.

Objective: To evaluate the effects of PD145065(non-selective endothelin(ET)receptor antagonist)on injured spinal cord and explore mechanisms of how ET plays a role in secondary injury following spinal cord injury(SCI).Methods:Spinal cord of rat was traumatized by compression(50g,1min).PD145065 or vehicle was administered intrathecally 10 minutes before SCI.Alterations of spinal cord blood flow(SCBF),molondialdehyde(MDA),the total content of intracellular calcium([Ca2+]i),Evans blue(EB),and water in spinal cord were inspected.Results:SCBF of injured area decreased obviously 5 minutes after SCI.SCBF was 75.23±9.21% of baseline 5 minutes after SCI,57.06±7.35% 2 hours.SCBF of adjacent area decreased lower.SCBF was 79.82±7.98% of baseline 30 minutes after SCI.SCBF of injured and adjacent areas did not recover 4 hours after SCI.The contents of MDA,[Ca2+]i,EB and water in traumatized spinal cord were significantly more than that of sham(P<0.05)。PD145065 ameliorated SCBF of injured area obviously and abolished the decrease of SCBF of adjacent area.The contents of MDA,[Ca2+]i,EB and water in spinal cord of PD145065 treated group were significantly less than that of saline treated group(P<0.05).Conclusion:PD145065 has protective effects on traumatized spinal cord in early phase.ET and its receptors may play a role in secondary injury following SCI by multiple pathways.ETA/ETB receptor antagonist may be useful in treatment of clinical SCI.

Objective To investigate the correlation between the recruits' gastrointestinal hormone level and military stress.Methods 150 army recruits were included for the study.The gastrointestinal symptom and mental status of army recruits were investigated with questionnaires as well as Symptom Checklist 90(SCL-90).Serum gastrin,vasoactive intestinal peptide(VIP),cortisol,?-endorphine(?-EP)levels were determined with radioimmunological techniques before and after live ammumition shooting training.All the army recruits underwent endoscopic and abdominal ultrasonographic examinations,and the presence of Helicobacter pylori(Hp)was detected by rapid urease test(RUT).Results 17 army recruits developed erosive gastritis or peptic ulcer after shooting training.Hp was detected in 94 army recruits(62.7%),the infectation rate was significantly higher than that of normal people(55%,P

Objective To evaluate the effect of 3-dimmentional conformal radiotherapy (3-DCRT) for mediastinal metastasis from esophageal carcinoma after surgery.Methods Sixty-three such patients were treated by 3-DCRT. Tumor diameter was: cm 20 patients. Positive supraclavicular lymph node was found in 9 patients. The number of tumor at the upper right, upper left and upper median mediastinum was 27, 27 and 20. All patients received 3-DCRT to the dose of 40?Gy (2?Gy/f, 5f/w), after resetting of portals, the dose was boost to 64~70?Gy by 3?Gy/f, 5f/w. Dose of the patients who had been irradiated was boosted to 50?Gy without further positioning. Results Complete response rate and partial response rate were 43% and 48% one month after the treatment was concluded,with no progression of disease. The 1-, 2- and 3-year survival rates were 75%, 43% and 15%. Conclusions Three-dimmentional conformal radiotherapy, with little side-effects, can markedly improve the local control rate and suvival rate of patients with mediastinal metastasis from esophageal carcinoma after surgery.

9.Therapeutic observation on superficial needling with different frequencies for intractable facial paralysis
Journal of Acupuncture and Tuina Science 2019;17(6):432-437
Objective:To obverse the therapeutic effect of superficial needling with different frequencies for intractable facial paralysis. Methods: A total of 120 patients with intractable peripheral facial paralysis were allocated into a superficial needling with high frequency group (150 times/min), a moderate frequency group (100 times/min) and a low frequency group (50 times/min) according to the random number table method. The Toronto facial grading system (TFGS) was used to evaluate facial nerve functions before treatment and after 2 weeks and 4 weeks of treatment respectively. The electromyography (EMG) test of the mandibular branch of facial nerve was used to compare the motor nerve conduction velocity (MCV), sensory nerve conduction velocity (SCV) and monophasic action potential (MAP) among different groups, and was done before treatment and after 4 weeks of treatment. The clinical efficacy was also compared. Results: After 2 weeks and 4 weeks of treatment, the changes of TFGS scores in the three groups all showed statistical significance (all P<0.05), and the TFGS score in the low frequency group was substantially higher than that in the other two groups. After treatment, the changes of the MCV and SCV in the three groups all showed statistical significance (all P<0.05), and the results in the low frequency group were higher than those in the other two groups; the change of MAP in the three groups showed no statistical significance (P>0.05). The total effective rate was 65.0%, 80.0% and 95.0% in the high frequency group, moderate frequency group and low frequency group respectively, and the between-group differences showed statistical significance (P<0.05). Conclusion: Compared with the superficial needling with high and moderate frequencies, superficial needling with low frequency can produce more significant clinical efficacy for intractable facial paralysis.
