Objective:To draw a mapping knowledge domains of research status and trend in counseling and psychotherapy field from 2001 to 2014 by Bicomb software.Methods:CNKI,Wan Fang,VIP were searched and re-trieval time ranged from January 1,2001 to December 31,2014.Bicomb and SPSS20.0 software were applied to conduct co-word matrix,similarity matrix and multidimensional scaling.Results:Setting 30 and more as the fre-quency standard,60 high frequency keywords were abstracted after analyzing 6546 articles.Cluster analysis showed that studies about counseling and psychotherapy mainly focus on seven categories including the effectiveness of counseling and psychotherapy,children and adolescents'mental health and counseling,the localization of counseling and psychotherapy,the process of counseling and psychotherapy,counseling and treatment principles,relationships of psychotherapy and ideological work in colleges as well as theories and practices in counseling and psychotherapy field.The mapping knowledge domain showed that four aspects of high frequency keywords in counseling and psy-chotherapy field basically correspond to the 7 categories made by cluster analysis.Conclusions:The present study demonstrates that psychological counseling and treatment development of our country is still in the stage of investi-gating effect.Future researches should attach importance to the integration research of psychological counseling and ideological and political education in colleges,the rise and development of internet psychological counseling and the development of children and adolescent mental health.

Objective To investigate the clinical features, diagnosis and treatment of aortic dissection. Methods Clinical data including manifestations,imageology, treatment and turnover in 23 patients with aortic dis-section, hospitalized in our hospital from January 2006 to April 2008, were retrospectively analyzed. Results There were 8,5 and 10 cases classified in type Ⅰ ,type Ⅱ and type Ⅲ,all of them were complicated with hypertension. Typi-cal syndromes were manifested in 20 patients (86.9%) and were not in the others (13.0%). Surgical operation were performed in 6 patients of type Ⅰ and 5 patients of type Ⅱ, and endovascular repairments were performed in Ⅰ patient of type Ⅰ and 10 patients of type Ⅲ. All the patients were recovered except that two patients of type Ⅰ died. Conclusions Most patients with aortic dissection present typical manifestision. CT or MRI is one of the most valua-ble diagnosis. The patients in type Ⅰ and type Ⅱ should be treated with the surgical operation, and the patients in type Ⅲ with endovascular stent-graft repairment.

A total of 120 patients with Ⅲ/Ⅳ degree hemorrhoids were randomly divided into 3 groups.Self-made drainage(A group),traditional device(B group)and stuffing(C group) were used at the end of operation.The patient postoperative complications and satisfaction were observed and compared.The results showed that postoperative abdominal distension,pain,medical dressing dampness and satisfaction were better in A group than those in B and C groups(all P <0.01).Postoperative abdominal distention in B group was lighter than that in C group and medical dressing dampness less in C group than that in B group (all P < 0.01).Thus the self-made drainage device may reduce the levels of postoperative abdominal distension,pain and medical dressing dampness and increase postoperative patient satisfaction.

Objective To explore the effect of endothelial progenitor cells (EPCs) on the proliferation of co-cultured rat vascular smooth muscle cells(VSMCs). Methods Mononuclear cells were isolated from fresh cord blood by 6% hydroxyethyl starch (HES) and density gradient centrifugation. Isolated mononuclear cells were cultured in EGM-2 medium supplemented with 20% fetal bovine serum (FBS), VEGF,bFGF and other growth factors. Biological features of EPCs were observed at different time points, and EPCs were identified by morphology, fluorescence double-staining and flow cytometry. Indirect immunofluorescence was performed to analyze the expression of α-SM-actin, calponin of VSMCs special antigen. Co-culture system of EPCs and VSMCs was established by transwell permeable support. FBS (20%) was used to stimulate the proliferation of VSMCs. In a VSMCs/EPCs co-culture system, the DNA synthesis ability, total protein level and cell cycle of VSMCs were determined by BrdU marking method,protein quantitation and flow cytometry after co-culture for 6, 12, 24,48 and 72 h. Results After co-culture for 12, 24, 48, and 72 h, the DNA synthesis ability and total protein level of VSMCs significantly decreased compared with the control group(P<0.05). Flow cytometry showed that the percentage of S phase of VSMCs in VSMCs/EPCs co-cultured group significantly decreased and the percentage of G_1 phase increased markedly compared with the control group(P<0.05). The maximal inhibitory effect was observed at 48 h. Conclusion Early EPCs could inhibit the proliferation of VSMCs.

Objective In order to provide clinical evidence of reducing postoperative complications of procedure for prolapse and hemorrhoids and observe the effects of constipation on postoperative complications of procedure for prolapse and hemorrhoids.Methods One hundred and sixty cases of hemorrhoid were divided into two groups according to whether suffering from constipation:there were eihgty cases who were suffered from constipation in the experimental group and eighty cases who were not suffered from constipation in the control group.All patients' postoperative bleeding,anal edema,stool impaction and satisfaction were observed within 30 days and these data were compared and analysed by using SPSS 13.0 software.Results In the experimental group,the postoperative bleeding incidence was 37.5 % (30/80),the anal edema incidence was 31.3 % (25/80),the stool impaction inci dence was 8.6% (7/80),and the patients' satisfaction rate was 88.6% (71/80).In the control group,the postoperative bleeding incidence was 18.6% (15/80),the anal edema's incidence was 15.0% (12/80),the stool impaction incidence was 1.3% (1/80),and the patients' satisfaction rate was 97.5% (78/80).All the indexes above were different statistically in the two groups (P < 0.05).Conclusion constipation could increase complications and reduce the degree of satisfaction after procedure for prolapse and hemorrhoids.

Objective To observe the changes of serum potassium concentration in rectal cancer patients from the admission to before the operation,to provide clinical evidence for preventing serum potassium disorder during and after their operation.Methods Monitoring of the changes of serum potassium concentration of 40 cases of rectal cancer patients according to three time points including the first day of admission,before taking of cathartics and the morning before operation.They were divided into different groups according to their age(young,middle age and elderly group),gender(male and female group),diet(normal,decreased slightly and serious decline group) and course(long,middle and short course group) of disease.The serum potassium concentration was observed between each time point of each group and SPSS13.0 statistical software was used to analyze the changes above.Results The mean of all patients' serum potassium concentration was (4.09 ± 0.62) mmol/L on the first day of admission,was (3.83 ± 0.46) mmoL/L before taking of cathartics that was decreased compared to the former and there was significant difference (P < 0.01),it was (3.36 ±0.40) mmol/L on the morning of operation and had significant difference with the above two groups (P < 0.01).It hadn't significant difference between different gender and age groups at different time points (P > 0.05) except between the young group and the elderly group in the morning of the operation (P < 0.05).There were statistically significant differences between the different diet condition and different course at anytime point (P < 0.01).Conclusions The rectal cancer patients were possiblely in hypokalemia before operation,the causes might be relative to the long course of disease,the decreased diet,the aged and infirm,the diet structure change after admission and taking cathartics cleaning intestinal tract.
