Objective: To compare the cognition of cancer patients and their relatives,so as to provide references for cognitive intervention.Methods: Cognition questionnaire consists 19 questions to which most patients and their relatives concern.Sixty new cases of cancer patients and their relatives were included in this study.Results: Answers to the 5 following questions from the patients and their relatives were different with statistical significance: do you know the diagnosis(83% patients know,97% relatives know,?2=5.93,P=0.015);whether to inform patients of diagnosis or not(87% patients chose yes,65% relatives chose yes,?2=7.69,P=0.006);is it necessary to tell patient intimate therapeutic regimen(77% patients thought it is necessary,62% relatives thought it is necessary,?2=8.71,P=0.013);who decide the method(s) of treatment(7% patients and 17% relatives' answer is the patients,?2=7.19,P=0.028);if the treatment is unable to cure your disease,what would be your option(80% patients and 97% relatives chose treatment,?2=8.09,P=0.004).Different educational background(?2=5.63,P=0.018) and occupation(?2=4.10,P=0.043) affected their cognition on being informed of the intimate therapeutic regimen.Conclusion:Patients` and relatives` cognition of being informed of the diagnosis and therapy are diverse from each other.In communication with them,doctors must treat them respectively.

Objective To evaluate the therapeutic effetive,toxicity and survial rate of non-operation esophageal carcinoma patients treated by tegafur plus cisplatin combined with three-dimensional conformal radiotherapy (3D-CRT).Methods 184 cases of non-operation patients with esophageal carcinoma were divided into two groups.The cases of treatment group were treated by cisplatin and tegafur.The cases of control group were treated by cisplatin and 5-Fu.All patients received 3D-CRT,and the total radiation dose was 50-70 Gy.Each group had 14 cases treated with primary chemotherapy for 1 course,28 cases for 2 courses,and 50 cases without any chemotherapy.Results The recent effect rate was 69.57 ％ (64/92) in treatment group and 67.39 ％ (62/92) in control group,there was no statistical difference (x2 =0.101,P =0.874).Radioactive esophagitis and leukopenia were the main side effect of treatment.The treatment group was significantly lower than that of the control group,the difference had statistical significance.The 1-,2-and 3-year survival rates were 74.9 ％,61.6 ％,52.8 ％,respectively in treatment group and 75.8 ％,56.9 ％,48.0 ％,respectively in control group.The control group survival rates were significantly higher than the treatment group,the difference had statistical significance (x2 =7.325,P =0.007).Conclusions Cisplatin plus tegafur or 5-Fu combined with 3D-CRT is effective way of treatment for non-operation of esophageal carcinoma.The toxicity of cisplatin plus tegafur group is significantly lower than cisplatin plus 5-Fu group,therefor it can improve the quality of life of the patients obviously.

Objective To systematically review the efficacy and safety of mini-percutaneous nephrolithotomy (MPCNL) and flexible ureteroscopic lithotripsy (FURL) in management of lower pole kidney stones.Methods PubMed, Embase, Scopus, Cochrane library, CNKI, VIP and Wanfang Data were searched from the beginning of database to September 2016 and clinical trials that compared the two above operation for treatment of lower pole stones were collected.Two researchers independently filtered literature,extracted data and evaluated the methodological quality of research papers.The meta-analysis was performed using the RevMan 5.3 software.Results One randomized and seven non-randomized studies were analyzed, which consists of 621 patients including MPCNL group 327 cases, FURL group 294 cases.The results of meta-analysis showed that MPCNL was better than FURL in stones clearance (OR =2.65,95％ CI 1.58-4.46,P ＜ 0.01) and operative time (WMD =-21.86,95％ CI-28.52--15.20, P ＜ 0.01).FURL was better in hospital stay time (WMD =2.28,95％ CI 0.29-4.28, P =0.02), decrease in haemoglobin levels (WMD =0.78,95 ％ CI 0.68-0.89, P ＜ 0.01), bleeding (OR =5.11,95 ％ CI 1.12-23.31,P =0.04), transfusion(OR =7.04,95％ CI 1.59-31.15, P =0.01).There was no significant difference in fever,urinary tract infection, hematuria (P ＞ 0.05).Conclusions Both MPCN and FURL are safe and effective for the treatment of lower pole stones, MPCNL can get higher stone clearance rates and shorter operation time.However, FURL can get shorter hospitalization time and lower complication rates.

AIM:To determine the effects of Tongxinluo (TXL) on connexin 43 (Cx43) remodeling and ven-tricular arrhythmia ( VA) after myocardial infarction ( MI) in rats .METHODS:Male SD rats were randomly divided into sham-operated (sham) group (n=25) and operation group (n=75).The left anterior descending (LAD) was ligated in operated group , while the rats in sham group only underwent pericardiotomy .The rats in operation group which survived for 3 d after operation were randomly assigned to TXL group and MI group .The rats in TXL group was administrated with TXL (2 g? kg-1? d-1, intragastric administration) for 4 weeks, while normal saline was applied to the rats in sham group and MI group.The levels of interleukin-1β(IL-1β) and endothelin-1 (ET-1) in the tissue from the border zone were measured by ELISA after treatment .The distribution and the mRNA and protein expression of Cx 43 were detected by immunohisto-chemical staining , RT-PCR and Western blotting , respectively .The burst pacing was used to induce ventricular arrhythmia ( VA) .RESULTS:Compared with sham group , the levels of IL-1βand ET-1 and the incidence of VA were significantly increased , while the mRNA and protein expression of Cx 43 was markedly reduced with irregular distribution in MI group (P<0.05).Compared with MI group, the levels of IL-1βand ET-1 and the incidence of VA were significantly reduced , while the expression of Cx 43 at mRNA and protein levels was markedly increased with augmented linear distribution in the myocardial cell intercalated disc in TXL group (P<0.05).CONCLUSION:TXL reduces the incidence of VA after MI via inhibiting the Cx43 remodeling .

Objective To observe the effect of Huangxiong Kangshuan capsule on serum high-sensitivity C-reactive protein (hs-CRP) and interleukin-6 (IL-6) levels in patients with acute cerebral infarction. Methods Ninety-two patients with acute cerebral infarction admitted to the First Affiliated Hospital of Anhui University of Traditional Chinese Medicinefrom July 2013 to December 2016 were enrolled, and they were divided into an observation group (47 cases) and a control group (45 cases) by random number table. The control group was given conventional treatment of ischemic cerebrovascular disease, while the observation group was additionally treated by Huangxiong Kangshuan capsule orally taken, once 3 tablets, 3 times a day, on the basis of routine treatment; the duration of treatment was 2 weeks in both groups. After 2 weeks of treatment, the clinical effects of the two groups and the changes of serum hs-CRP and IL-6 levels were observed.Results After treatment, the levels of serum hs-CRP and IL-6 were decreased significantly compared with those before treatment in the two groups [observation group: hs-CRP (mg/L) was 6.18±2.17 vs. 14.11±3.01, IL-6 (ng/L): 28.10±11.47 vs. 120.83±24.51; control group: hs-CRP (mg/L) was 8.89±2.46 vs. 13.97±2.69, IL-6 (ng/L) was 49.48±16.43 vs. 115.25±24.05], and the degree of decline in the observation group was more significant than that in the control group [hs-CRP (mg/L): 6.18±2.17 vs. 8.89±2.46, IL-6 (ng/L): 28.10±11.47 vs. 49.48±16.43, bothP < 0.01]; the total effective rate of the observation group was significantly higher than that of the control group [87.2% (41/47) vs. 71.1% (32/45),P < 0.05]. Conclusion Huangxiong Kangshuan capsule can decrease the serum hs-CRP and IL-6 levels in patients with acute cerebral infarction, and has a role in brain protection and nerve function defect improvement.
