Objective To explore the value of endoscopic mini-incision greater saphenous vein harvesting for coronary artery bypass operation. Methods A total of 411 patients scheduled for coronary artery bypass operation were given either endoscopic vein harvesting(EVH Group,n=136) or open vein harvesting(OVH Group,n=275),based on patient's willingness.The operation outcomes and incision complications were compared between the two groups. Results The incidence of various incision complications was significantly lower in the EVH Group(18.4%,25/136) than in the OVH Group(36.7%,101/275)(?~2=14.406,P=0.000).As compared with the OVH Group,the EVH Group had lower incidences of edema(1.5% vs 35.3%;?~2=56.861,P=0.000),paraesthesia(7.4% vs 33.8%;?~2=33.937,P=0.000),hematoma(16.2% vs 27.3%;?~2=6.214,P=0.013),and incisional liquefaction(0.7% vs 8.7%;?~2=10.174,P=0.001) of the lower extemity.The total operation time were 226.3?28.5 min in the EVH Group and 224.7?19.2 min in the OVH Group,without significant difference between the two groups(t=0.673,P=0.502).Early graft failure happened in 1 case in each of the groups,without significant difference between the two groups(?~2=0.000,P=1.000).The numbers of distal coronary anastomoses were 3.6?0.8 in the EVH Group and 3.3?1.0 in the OVH Group,with significant difference(t=3.049,P=0.002). Conclusions Endoscopic greater saphenous vein harvesting can significantly reduce the morbidity associated with incision complications,whereas does not prolong the operative time,increase the incidence of early graft failure,and decrease the number of distal coronary anastomoses.

Objective To compare the difference of entrance dose between CR and amorphous silocon DR system in chest imaging, and to discuss their optimum exposure dose. Methods For CR and DR, different entrance dose was measured by dosimeter in chest phantom. The value of IQFinv was analyzed by CDRAD2. 0 software. Image quality difference between CR and DR was assessed by group t-test. The relationship between image quality and entrance dose was tested by using Pearson correlation analysis. The best IQFinv values in CR and DR system were achieved via ROC curve analysis, and the exposure dose was then calculated. Results There were direct correlation values between entrance dose and the value of IQFinv in CR and DR system, respectively( r =0. 893 ,0. 848 ,P < 0. 01 ) . The linear regression equation for DR was IQFinv =0. 0050 +3. 359, and for CR was IQFinv =0. 005D + I. 651 , where D was entrance dose. The difference of IQFinv value between CR and DR was significant(t = 5. 455 ,P < 0. 05). The best IQFinv value of the two groups from ROC analysis was 3.55. Conclusions With the entrance dose increased, the detection ability of contrast-detail was elevated in the two digital radiography systems. With equal entrance dose, the detection ability of DR in contrast-detail was superior to CR. With equal image quality, DR obviously decreased the radiation dose to the patients.

Objective To evaluate the effects of alpha-lipoic acid (α-LA)on autophagy in human skin fibroblasts (HSFs). Methods HSFs at passage 3 - 5 were divided into several groups to be cultured with α-LA at final concentrations of 0, 0.01, 0.05, 0.10, 0.15, 0.20 and 0.50 mmol/L for 4, 12 and 24 hours, respectively. Methyl thiazolyl tetrazolium(MTT)assay was performed to evaluate cellular proliferative activity, monodansylcadaverin(MDC)staining to determine autophagy levels, and Western blot to measure the expression of the microtubule-associated protein 1 light chain-3B(LC3-B). Results After incubation for 24 hours, there was a significant difference in the proliferative activity of HSFs among all the groups (F = 10.41, P < 0.05), while no significant differences were observed after incubation for either 4 or 12 hours (F = 2.85, 1.34, respectively, both P > 0.05). MDC staining also showed a significant difference in the percentage of autophagosome-positive cells among all the groups after 24-hour incubation (F = 8.03, P < 0.05), but no significant difference after either 4- or 12-hour incubation (F = 0.11, 0.10, respectively, both P > 0.05). Western blot revealed that the degree of conversion from LC3-Ⅰ to LC3-Ⅱ(LC3-Ⅱ/LC3-Ⅰratio)was significantly different among all the groups after 24-hour incubation (F = 37.49, P < 0.05), but similar after 4- and 12-hour incubation (F = 3.38, 2.13, respectively, both P > 0.05). Conclusion α-LA may inhibit basal autophagy in HSFs.

Objective To evaluate the effects of ultraviolet A (UVA) on autophagy in human skin fibroblasts (HSFs).Methods Cultured HSFs were randomly divided into chronic and acute UVA radiation groups.HSFs in the chronic UVA radiation groups were irradiated with UVA at 5,10 and 20 J/cm2 separately once a day for 4 consecutive days,with HSFs receiving no radiation serving as the chronic radiation control group;HSFs in the acute UVA radiation groups received a single session of radiation with 5,10,30 and 60 J/cm2 UVA separately,with HSFs receiving no radiation serving as the acute radiation control group.After additional culture for different durations,methyl thiazolyl tetrazolium (MTT) assay was performed to evaluate the proliferative activity of HSFs,monodansylcadaverin (MDC) staining to determine autophagy levels,and Western blot analysis to track the conversion of the microtubule-associated protein 1 light chain-3 (LC3)-Ⅰ to LC3-Ⅱ.Statistical analysis was carried out by using one-way analysis of variance followed by Students-Newman-Keuls (SNK) test for multiple-group comparisons and by the independent sample t test for two-group comparisons.Results The cellular proliferative activity significantly decreased in the 3 chronic radiation groups at 1 hour after the final UVA radiation compared with the chronic radiation control group (F =155.5,P ＜ 0.05),and in the 4 acute radiation groups at 1,6 and 12 hours after UVA radiation compared with the acute radiation control group (F =1 335,1 649,2 774,all P ＜ 0.05).MDC staining showed that the autophagy levels in HSFs significantly increased in the 3 chronic radiation groups after UVA radiation compared with the chronic radiation control group (F =748.62,P ＞ 0.05),but showed no significant changes in any of the acute radiation groups at 1,6 or 12 hours after UVA radiation compared with the acute radiation control group (F =0.014,0.004,0.002,all P ＞ 0.05).The ratio of LC3-Ⅱ to LC3-Ⅰ was significantly elevated in all the 3 chronic radiation groups at 1 hour after UVA radiation compared with the chronic radiation control group (t =9.002,21.772,18.33,all P ＜ 0.05),but experienced no obvious changes in any of the acute radiation groups at 1,6 or 12 hours after UVA radiation compared with the acute radiation control group (F =0.13,0.27,0.06,all P ＞ 0.05).Conclusion Chronic UVA radiation can upregulate autophagy levels in HSFs,but acute UVA radiation has no evident effects on it.

OBJECTIVE: To analyze the subjective and objective burden given by patients with mental disorder in a family, and probe into the family interference therapy model.METHODS: The method of looking up documentation was used to investigate the information about the family of patients with mental disorder. The study is to mainly investigate the burden status of Chinese family, observe the effect of social consensus on the family of the patients with mental disorder, detail explain and analyze the different burden and needs of the family of the patients with mental disorder in urban and rural area. Ant the same time, the family interference therapy model was introduced to apply in China.RESULTS: Objective family burden mainly includes economic burden and physical burden induced by earing for patients. Subjective burden are mainly mental crucifixion of the family member given by the patients with mental disorder; even severe mental injury. Social stigma can bring more serious subject burden to the Chinese family. Mental health services center reduces the depression of the family, and single-family session was used to further treat mental weakness and internal conflict of each family. The object to establish family support group was mainly to share the education and experience.CONCLUSION: Family members of the patients with mental disorder bear the subjective and objective burden. Family interference therapy can postpone the relapse of mental disorder, also improve the status of the patient in family and the harmonious degree of the whole family.
