Objective To compare the effects of target-controlled infusion (TCI) of propofol and remifentanil and inhalation anesthesia on the stress response in patients undergoing laparoscopic cholecystectomy (LC). Methods Selective LC was performed on 60 cases. Before the surgery,the patients were randomly divided into experiment (TCI of propofol and remifentanil) and control (standard general anesthesia combined with inhalation of fluorinated alkane and laughing gas) groups with 30 cases in each. The serum levels of cortisol and IL-6 were detected before the induction (t1) and 20 minutes after pneumoperitoneum (t2). In addition,the MAP and HR of the two groups were monitored at seven time points. Results The serum levels of cortisol and IL-6 in the experiment group were similar to those in the control at t1 [Cortisol:(227.48?50.81) ?g/L vs (233.21?41.02) ?g/L,t=0.481,P=0.633; IL-6:(105.99?30.65) ng/L vs (111.20?34.80) ng/L,t=-0.615,P=0.541],but significantly lower at t2 [Cortisol:(241.00?69.11) ?g/L vs (354.70?37.55) ?g/L,t=7.918,P=0.000; IL-6:(116.06?30.89) ng/L vs (172.73?23.54) ng/L,t=-7.992,P=0.000]. The MAP and HR in the experiment group were significantly lower than those in the control at t2 to t5 (5,10,15,and 20 minutes after the pneumoperitoneum; P

Objective To evaluate the effectiveness of training management applying character color theory in patients with peritoneal dialysis on the compliance and dialysis effect. Methods Of 95 patients undergoing catherization for peritoneal dialysis from January 2013 to May 2014 in the peritoneal dialysis center,72 patients accepted character color psychological questionnaire designed by Le Jia for character color analysis.72 patients were divided into matched control group and experimental group according to their choice with red, yellow, blue, green character color, 36 cases in each group. The control group adopted the traditional training way of accepting 7 days′training course teached by the professional nursers,one follow- up management each month. According to the difference of character color,the experimental group were given different education training courses, interactive learning, and follow- up time. After 6 months′follow- up, the two groups adopted peritoneal dialysis self management behavior questionnaire designed by Liu Pengfeng and self- efficacy scale designed by education research center for chronic disease in Amercian Stanford University. The score of self management ability and self- efficacy and the change of load capacity, blood pressure, dialysis adequacy and biochemical indicators of the two groups were analyzed. Results In the control group and experimental group,the score of self management ability and self- efficacy and the level of dialysis adequacy were statistically significant, respectively, (5.64±1.57) points vs. (6.75±1.32) points;(5.22±1.48) points vs. (6.69±1.43) points; 1.64±1.64 vs 1.85±0.13.Z and P values were respectively -2.969, -3.828, -6.361, and 0.003, 0.000, 0.000.Edema happened in the control group was 24 cases, and 11 cases in the experimental group. P and χ2 values were 0.013 and 10.017.Systolic blood pressure and di-astolic blood pressure were respectively (147.78±15.69) mmHg (1 mmHg=0.133 kPa) vs.(135.39±9.01) mmHg,(95.86±7.50) mmHg vs. (83.94±7.46) mmHg in the two groups. Z and P values were respectively -3.843, -5.666, and 0.000, 0.000.There was significant difference between the experimental group and control group. Conclusion The education and training applying character color feature in patients with peri-toneal dialysis can mobilize the initiative of self management, improve the patients' self- care competency and self-efficacy, enhance patients′compliance, that can improve the effect of peritoneal dialysis.

Objective To assess the noninvasive index for diagnosing the degree of esophageal varices (EV) in patients with hepatitis B virus (HBV)-related cirrhosis. Methods The clinical data of 112 patients with HBV-related cirrhosis were studied retrospectively. The patients were divided into non-EV (NEV) group (30 cases) and EV group (82 cases) according to the results of gastroscopy. In EV group, there were mild varices in 21 cases (mild EV group), moderate varices in 47 cases (moderate EV group) and severe varices in 14 cases (severe EV group). The age, gender, platelets, glutamyl transpeptidase, prothrombin time, albumin, bilirubin, portal vein diameter, spleen vein diameter and thickness of spleen were compared, and the relationship was analyzed between each index and EV. Results There were no statistical differences in gender, age, albumin, bilirubin, prothrombin time and glutamyl transpeptidase between NEV group and EV group (P>0.05). The portal vein diameter, spleen vein diameter and thickness of spleen in EV group were significantly higher than those in NEV group:(14.1 ± 3.1) mm vs. (10.6 ± 2.3) mm, (8.9 ± 2.1) mm vs. (7.6 ± 1.6) mm and (4.8 ± 0.9) mm vs. (3.8 ± 1.0) mm, the platelets in EV group was significantly lower than that in NEV group:(86.8 ± 20.2) × 109/L vs. (163.5 ± 18.1) × 109/L, and there were statistical differences (P<0.01 or<0.05). The portal vein diameter, spleen vein diameter and thickness of spleen in moderate EV group and severe EV group were significantly higher than those that in NEV group and mild EV group: (13.5 ± 2.1) and (14.8 ± 3.6) mm vs. (10.6 ± 2.3) and (11.2 ± 3.1) mm, (8.3 ± 2.1) and (9.1 ± 1.1) mm vs. (7.6 ± 1.6) and (8.1 ± 1.9) mm, (4.7 ± 1.1) and (4.9 ± 0.9) mm vs. (3.8 ± 1.0) and (4.1 ± 1.2) mm, the platelet levels were significantly lower than those in NEV group and mild EV group: (72.8 ± 11.6) × 109/L and (63.8 ± 15.6) × 109/L vs. (163.5 ± 18.1) × 109/L and (100.2 ± 10.3) × 109/L, and there were statistical differences (P<0.05). The area under curve of response operating characteristic for predicting the presence of moderate and severe EV with portal vein diameter and platelets were 0.719 and 0.735, and the cut off value were 14 mm and 69 × 109/L. Conclusions The portal vein diameter and platelets can predict the presence of moderate and severe EV in patients with HBV-related cirrhosis.

Objective To study the clinical characteristics, diagnosis, treatment and prognosis of cancer metastasis to the thyroid gland. Methods A restropective review was performed on 35 patients with cancer metastasis to the thyroid gland in our hospital from 1958 to 2010. Diagnosis was confirmed by fineneedle aspiration cytology or histopathology in all cases. Results Primary tumor origin was identified in all but three cases. The lung was the most common primary tumor site( n = 16), followed by esophagus( n =9),breast ( n = 2), kidney ( n = 2), hypopharynx ( n= 1 ), nasopharynx ( n = 1 ) and soft palate ( n = 1 ). Thyroid metastasis was found before the diagnosis of the primary tumor was established in 12 cases; in the other 23 cases, the time lapse from diagnosis of the primary tumor to metastasis to the thyroid gland ranged from 0- 168 months, median 24 months. In 6 patients, this interval was more than 36 months. Fine-needle aspiration cytology ( FNAC ) confirmed metastatic malignancy in 7 patients, histology in 24, combined application confirmed the diagnosis in 4. After the metastasis to the thyroid gland was established, the median survival time for the entire group was 11.5 months, the 1-, 3- and 5-year survival rate was 43.8%,27. 8% and 11.9%, respectively. 28 patients were treated surgically, and 7 received nonsurgical therapy.The overall survival rate in the surgical group was higher than that in the nonsurgical group (P <0. 01 ). In those patients with metastatic cervical lymph nodes, median survival time did not vary from patients undergoing thyroidectomy with neck dissection to those undergoing thyroidectomy alone (P > 0. 05 ).Conclusions Metastasis of carcinoma to the thyroid gland has an occult occurrence, thyroid metastases can be detected conclusively with FNAC. Metastasis to the thyroid gland implies advanced malignant tumors,often with poor prognosis.
