Objective To study on ERCP findings correlating with tumor size and staging of pancre- atic cancer(PC).Methods We selected 35 patients with PC who were identified by surgery and/or pathol- ogy and had undergone ERCP with clear imaging findings.The lengths of pancreatic duct and common bile duct stricture as well as the diameter of upstream dilated pancreatic or bile duct were measured on ERCP films.The ralationship among ERCP findings and tumor size and JPS T-stage of PC were analysed by correla- tion analysis.Results Of the 35 patients with PC,ERCP showed the pancreatic duct stricture in 25 and cut- off of pancreatic duct in 10(7 of them,the lesion lengths were revealed after a guide wire advanced beyond the obstructive site)and common bile duct stricture in 31.The correlation coefficients between tumor size and lengths of pancreatic duct or common bile duct stricture were 0.709(P=0.0001)and 0.540(P=0.0053) respectively.The correlation coefficient between JPS T-stage and lengths of pancreatic duct stricture was 0.514(P=0.0052).Conclusion The length of pancreatic duct stricture in ERCP was positively correlated with the tumor size and staging of PC.But it is not consistent when the length of stricture is rather short.The lengths of bile duct stricture also have some effects on predicting the tumor size of pancreatic head cancer.

Objective To comprehensively analyze the nursing measures of early thrombolytic therapy for acute myocardial infarction. Methods 140 patients with acute myocardial infarction admitted in our hospital from October 2013 to October 2016 were randomly divided into control group (70 cases) and experimental group (apply early thrombolytic care on the basis of routine nursing method, 70 cases) according to different nursing methods. SPSS20.0 statistical software was used to analyze the incidence of complications, mean hospitalization time, average bedridden time and total satisfaction. Results The average hospital stay and the average length of stay in the experimental group were much shorter than those in the control group (P<0.05). The total score of the experimental group was much higher than that of the control group (P<0.05). The complication rate of the experimental group was much lower than that of the control group (P<0.05). Conclusion Nursing measures for early thrombolytic therapy in patients with acute myocardial infarction can significantly reduce the incidence of complications in patients.

Objective To explore the effect of different indexes on evaluating insulin resistance in obese children. Methods Oral glucose tolerance test (OGTT) was performed in obese children (n= 61) and age - matched normal volunteers( n= 23) Serum glucose and insulin levels were determined at 0,30,60,120,180 min after OGTT, insulin resistance was estimated by homeostasis model assessment of insulin resistance (HOMA-IR). Indexes such as the ratio of area under the curve of glucose(AUCG)/area under the curve of insulin(AUCI), the ratio of fasting blood sugar(FBG) and fasting blood insulin (FINS) were meanwhile calculated. Results The level of serum FINS was significantly higher in obese children(P

Diversified teaching methods including traditional teaching,problem based learning,interactive teaching and team cooperation teaching were adopted in the process of teaching.Problem based learning can stimulate students' learning interests; interactive teaching can improve the students' hands-on ability and team cooperation teaching can cultivate students' cooperation spirits.Diversified teaching mode made different teaching methods integrated and complemented each other,forming a special teaching mode for the course of functional experiment.

To study the interaction of drugs of different properties, namely puerarin, borneol and catalpol in the process of in- clusion, in order to explore the inclusion regularity of multi-component and multi-property traditional Chinese medicine compound in- clusions. With HP-β-CD as the inclusion material, the freeze-drying method was used to prepare the inclusion. The inclusion between puerarin, borneol and catalpol was tested by measuring the inclusion concentration, DSC and X-ray diffraction. According to the find- ings, when insoluble drugs puerarin and borneol were included simultaneously, and puerarin was overdosed, puerarin included was almost equal to puerarin included, and borneol was not included. When puerarin was under-dosed, and HP-β-CD was overdosed, borne- ol was included, and the simultaneous inclusion was lower than the separate inclusion of borneol. When water-soluble drug catalpol was jointly included with puerarin or borneol, the simultaneous inclusion was almost the same with their separate inclusion, without charac- teristic peak of catalpol in DSC and X-ray diffraction patterns. There is a competition in the simultaneous inclusion between water-solu- ble drugs puerarin and borneol and a stronger competition in puerarin. The water-soluble drug catalpol could be included with HP-β-CD with no impact on the inclusion of puerarin or borneol.

Objective To determine the levels and significance of Krebs von den lungen-6(KL-6), pulmonary surfactant protein A (SP-A), SP-D and interleukin (IL)-6 in patients with connective tissue disease interstitial lung disease (CTD-ILD). Methods The serum KL-6, SP-A, SP-D and IL-6 in all subjects were detected and the imaging and pulmonary function were recorded t test, χ2 test, non-parametric test, ANOVA and correlation analysis were used for data analysis. Results ① The levels of serum KL-6, SP-A, SP-D, IL-6 in the CTD-ILD group [551.4 (428.2, 883.5) U/ml, 938.4(435.2, 2324.7) pg/ml, 90.7 (80.7, 100.3) ng/ml and 30.4 (22.9, 41.7) pg/ml; P all<0.05] was significantly higher than that in the CTD group [192.9 (139.2, 266.2) U/ml; 458.0 (372.6, 529.0) pg/ml; 80.0 (71.2, 98.3) ng/ml; 18.6 (4.9, 31.0) pg/ml, Z=-5.383, -3.76, -2.123,-3.903, P all <0.05]; and higher than healthy controls (n=30) [183.2(141.9, 216.6) U/ml; 229.0(162.0, 248.0) pg/ml;50.8(26.1, 96.4) ng/ml;7.1(3.7, 8.7) pg/ml, Z=-5.801,-8.13, 2.272, 3.266;P all<0.05].②The levels of KL-6 in pulmonary HRCT for active ILD group was significantly higher than the non-active ILD group [998.5 (640.3, 1293.3) U/ml vs 565.0(434.0, 799.5) U/ml, Z=2.182, P=0.023], there was no statistical difference in the levels of SP-A, SP-D, IL-6 between the 2 groups. ③ Spearman correlation analysis showed that KL-6 was negatively correlated with forced vital capacity (FVC%);SP-D, IL-6 and diffusing capacity of carbon monoxide (DLCO %). ④ Logistic multiple regression analysis showed that KL-6 [OR=1.017, P=0.002, 95%CI (1.006, 1.028)], SP-A [OR=1.023, P=0.009, 95%CI (1.006, 1.041)], SP-D [OR=1.175, P=0.009, 95%CI (1.075, 1.264)], IL-6[OR=1.213, P=0.001, 95%CI(1.088, 1.354)] were the risk factors for ILD. Conclusion Serum KL-6, SP-A, SP-D and IL-6 are significantly increased and correlate with CTD-ILD. KL-6 is related to the pulmonary inflammatory disease and vital capacity, while SP-D and IL-6 are related to diffusion function.

Objective: To observe the clinical efficacy of acupuncture plus navel acupuncture for patients with urinary retention after radical hysterectomy for cervical cancer. Methods: A total of 64 patients with urinary retention after radical hysterectomy for cervical cancer was divided into a navel acupuncture group (22 cases), an acupuncture group (18 cases) and an acupuncture plus navel acupuncture group (24 cases). All three groups received bladder function training and neuromuscular electrical stimulation. In addition, navel points were combined in the navel acupuncture group. Electroacupuncture was conducted to Qihai (CV 6), Zhongji (CV 3), Dahe (KI 12), Shuidao (ST 28), Ciliao (BL 32) and Huiyang (BL 35) in the acupuncture group. The acupuncture plus navel acupuncture group received both treatments. The catheter was removed after 3 d of treatment. Spontaneous urination, residual urine volume, urinary catheter dependence and recurrence after 3 d, 6 d and 9 d of treatment in each group were observed, respectively. Results: In the acupuncture plus navel acupuncture group, the markedly effective rates after 3 d, 6 d and 9 d of treatment were significantly higher than those in the navel acupuncture group and the acupuncture group; the urinary catheter dependence was lower than that of the other two groups, and the differences were statistically significant (P<0.05, P<0.01); the spontaneous urination time was shorter than that of the navel acupuncture group and the acupuncture group, and the differences were statistically significant (P<0.05, P<0.01); the residual urine volume was significantly less than that of the navel acupuncture group and the acupuncture group, and the differences were statistically significant (both P<0.01). After the catheter was removed, recurrence was observed from the next day after spontaneous urination was resumed. There were 2 cases of recurrence in the navel acupuncture group, 2 cases in the acupuncture group and 1 case in the acupuncture plus navel acupuncture group. The recurrence rate of the acupuncture plus navel acupuncture group was significantly lower than that of the navel acupuncture group and the acupuncture group (both P<0.01). Conclusion: Acupuncture plus navel acupuncture has satisfactory efficacy for urinary retention after radical hysterectomy for cervical cancer. It can significantly shorten the urinary retention time, reduce the patient's dependence on urinary catheter, and reduce the residual urine volume.
