目的 探讨高频经颅磁刺激治疗对 PSD 伴失眠患者的抑郁情绪及睡眠质量的疗效。方法 对63例PSD患者随机分为联合组32例(10Hz高频rTMS+艾司西酞普兰)及药物组31例(艾司西酞普兰+假刺激),每周5次,共治疗4周。于治疗前及治疗后4周末分别对两组患者进行HAMD、PSQI评分及多导睡眠监测。。结果 rTMS 治疗前,2组HAMD、PSQI评分及睡眠参数比较均无差异;治疗后第4周末,两组HAMD评分、PSQI评分、总睡眠时间、睡眠效率及快眼动睡眠期比例均较治疗前改善;研究组HAMD评分下降幅度较对照组明显,而PSQI评分下降幅度及相关睡眠参数改善无差异。结论 高频rTMS治疗对PSD的抑郁症状疗效更明显,而对睡眠质量及睡眠结构的改善则与药物治疗疗效相当。

Objective To investigate the effect of high frequency transcranial magnetic stimulation on depression and sleep quality in poststroke depression patients with insomnia. Methods 63 patients with PSD were randomly divided into observation group (n=32)and control group (n=31). Both groups were treated by 10~20 mg escitalopram citalopram for 4 weeks. The patients in observation group also accepted 10 Hz rTMS 10 times (i.e., as a course), while the patients in control group were treated by sham stimulation. At the baseline and 4th week, the 17-item Hamilton depression scale (17-HAMD), Pittsburgh Sleep Quality Index (PSQI)and polysomnography (PSG)were evaluated. Results The sleep parameters, PSQI scores and HAMD scores among two groups had no significant difference at baseline. After 4 weeks treatment, the HAMD score, PSQI score, total sleep duration, sleep efficiency and proportion of rapid eye movement sleep in both groups were improved compared with those before treatment. The descend range of HAMD score in observation group was larger than that in control group (t=2.590,P=0.012), while the descend range of PSQI scores(t=0.897,P=0.373)and the change of the sleep parameters in the two group had no obvious difference. Conclusion High frequency rTMS has better curative effect than antidepressant therapy on depressive symptoms of PSD,while there was no difference on the effect to improve the sleep quality and sleep structure of PSD between these two treatments.

目的 调查临床医学生医患沟通能力的现状,分析其影响因素。方法 采用《医患沟通技能评价表（SEGUE量表）》对广州市某三甲医院的155名临床医学生进行调查。结果 临床医学生沟通技能总成绩得分率只有58.9%,在5个维度中,沟通结束方面得分率最高,为82.9%,而理解病人方面得分率最低,只有45.5%。性别、接受医患沟通相关培训次数不同的临床医学生,其沟通能力差异有统计学意义（P﹤0.05）。结论 临床医学生的医患沟通能力总体水平有待提高,特别是在理解病人方面。性别和参加医患沟通培训次数是临床医学生沟通能力的影响因素,应加强对医学生在共情能力、情感支持、移情等方面能力的培训,以提高医患沟通能力。

Objective To analyze the expression of erythropoietin （EPO） and erythropoietin receptor （EPOR） in hepatocellular carcinoma （NCC） and normal tissues,and their relationship with hepatocyte microvessel density （MVD）. Methods Thirty specimens of hepatocellular carcinoma hepatectomy were selected from our hospital. The liver tissue at the edge of the tumor was taken as a control,and 10 cases of normal liver tissue were used as a negative control. The expression levels of EPO and EPOR in each tissues were detected by enzyme-linked immunosorbent assay （ELISA）,and microvessel density （MVD） was detected by immunohistochemistry. The differences of EPO,EPOR and MVD between each tissues were compared. The relationship between EPO,EPOR,MVD and tumor pathological features in NCC was analyzed. The relationship between EPO and EPOR expression levels and MVD was analyzed. Results In HCC tissues,EPR,EPOR and MVD were higher than those in adjacent tissues and normal tissues. The difference was statistical difference （P<0.001）. EPR,EPOR and MVD were not statistically significant in adjacent tissues and normal tissues. P>0.05）. The levels of EPR,EPOR,and MVD in tumors with tumor size >5 cm,invasion of the capsule,distant metastasis,and high-differentiation were higher than those of tumor size ≤ 5 cm,no capsule invasion,no distant metastasis,and poor differentiation. The difference was statistical difference （P < 0.05）. Person correlation analysis showed that the correlation coefficient between EPO expression level and MVD was r=0.651 （P<0.001）,and the correlation coefficient between EPOR expression level and MVD was r=0.620 （P<0.001）. Conclusion EPO,EPOR and MVD are highly expressed in HCC,and are related to tumor size,local invasion,distant metastasis and differentiation. The mechanism may be related to EPO and EPOR increasing MVD.

Objective To observe the clinical effect of Jiajianxiangshaliujunzi decoction combined with triple therapy for chronic atrophic gastritis. Methods We selected 100 cases of patients with chronic atrophic gastritis of intertwined,and divided them into the control group and the observation group randomly with 50 cases in each group. The control group was given triple therapy for treatment,while the observation group was additionally given Jiajianxiangshaliujunzi decoction based on the syndrome differentiation for treatment. We observed the changes of clinical symptoms and levels of superoxide dismutase（SOD） and malondialdehyde（MDA） in serum of both groups. The negative conversion rate,recurrence rate and eradication rate of Helicobacter pylori （Hp） in 2 groups were statistically analyzed,in both groups and the clinical effect. Results After treatment,the total effective rates were counted: the observation group was 92%,and the control group was only 76%. The symptoms such as stomach distention,stomachache,distention and fullness,acid reflux,and diet reduction were reduced after the treatment. The difference between the two groups had statistical significance. In the two groups of stomachache,fullness and boredom,low appetite and acid regurgitation scores were all lower than those before treatment,and the differences were statistically significant. The negative rate of Hp in the observation group was 92%,while the negative rate of Hp in the control group was 68%. There was difference between the two groups in the negative rate of Hp. The levels of SOD in both groups were higher than those before treatment,and the levels of MDA were lower than those before treatment,differences being significant（P< 0.05）;the level of SOD in the observation group was higher than that in the control group,and the level of MDA was lower than that in the control group. Difference was statistically significant. （P< 0.05）. Conclusion Jiajianxiangshaliujunzi decoction combined with triple therapy for chronic atrophic gastritis may improve clinical symptoms of patients,and promote the negative rate of Hp as well as the clinical effect.
