Objective To evaluate the efficacy of endoscopic ultrasonography-guided celiac plexus radiation with iodine-125 (125I) seeds and celiac plexus neurolysis with absolute ethanol for pain relief secondary to advanced pancreatic cancer.Methods A retrospective analysis of 43 patients of advanced pancreatic cancer with moderate to severe abdominal pain in the Department of Gastroenterology,Shanghai Changhai Hospital from January 2017 to April 2018 was performed.20 patients underwent EUS-guided celiac plexus neurolysis (CPN),and 23 patients underwent EUS-guided celiac plexus radiation (CPR) with the implantation of 125I seeds around the celiac ganglia.The postoperative VAS score of abdominal pain,mean analgesic (MS Contin [morphine sulfate]) consumption and complications were compared between the two groups.Results There were no statistically significant differences between the two groups in the sex ratio (male/female,10/10 vs 14/9),average age [(64 ± 11) vs (64 ± 12)],lesion location (head/tail,7/13 vs 8/15] and TNM stage (Ⅲ/Ⅳ,9/11 vs 7/16),and the two groups were comparable.Compared with preoperative ones,the VAS score (3.0 points vs 5.5 points) and morphine dosage (30 mg vs 52.5 mg) were significantly lower in the CPN group one week after operation.In the CPR group,the VAS score (5.0 points vs 6.0 points) and morphine dosage (50 mg vs 55 mg) at 2 weeks after the operation were lower than those before the operation;the VAS scores of 4,8 and 12 weeks after the operation decreased to 3.0 points,and the dosage of morphine decreased to 30 mg,25 mg and 30 mg,respectively.The differences were statistically significant (P＜0.0001).Compared with the CPR group,at 2 weeks postoperatively the CPN group demonstrated a significantly higher decrease of VAS score (3.0 points vs 2.0 points),degree of morphine reduction (30 mg vs 10 mg) and rate of partial pain relief (70.0％ vs 4.3％).However,from 4 to 12 weeks postoperatively,the decrease in VAS score,the decrease in the dosage of MS Contin and the rate of partial pain relief in the CPR group were all significantly higher than those in the CPN group (P ＜ 0.05).There was no complete relief of pain in the two groups.No procedure-related deaths or serious complications were observed and only mild gastrointestinal adverse reactions occurred.Conclusions Two methods can both relieve abdominal pain in patients with advanced pancreatic cancer safely and effectively.CPR takes effect late but has advantages of good extent and long duration of pain relief.

Objective To evaluate the factors influencing the diagnostic positivity of endoscopic ultrasonography guided fine needle aspiration (EUS-FNA) for small size pancreatic carcinoma (SSPC) and the occurrence of the adverse events after the aspiration.Methods 51 patients with SSPC ≤2 cm in diameter treated in Changhai hospital from February 2008 to January 2015 were retrospectively studied.The gender,age,tumor diameter,location,the dilation of pancreatic ducts,the number of aspirations and the needle passages,the usage of negative pressure during aspiration,the pathological examination of the specimens and postoperative adverse events and the like were collected.Univariate analysis and logistic regression analyze were applied to determine the factors influencing the diagnostic positivity of EUS-FNA for SSPC and postoperative adverse events.Results Among the 51 patients,positive cytology outcome were identified in 30 patients,which were negative in 21 patients.Univariate analysis identified that there were no statistical differences on the age,sex,dilated pancreatic duct,the number of aspirations and needle passages between two groups (P value ＞0.05).The diagnostic positivity using the 10ml minor negative pressure was obviously higher than that using 20 ml negative pressure,and the differences were statistically significant (P =0.028).Multivariate logistic regression identified 10ml minor negative pressure was easier to obtain positive cytology outcome (Odds Ratio 0.2810,95％ CI 0.093-0.851).In addition,the number of passages in patients with postoperative adverse events was greater than those without postoperative adverse events (30 vs 20),and the difference was statistically significant (P =0.034).Conclusions The introduction of 10 ml negative pressure could improve the diagnostic positivity of EUS-FNA for SSPC,and the increased number of needle passages may increase the occurrence rate of postoperative adverse events.

Objective To explore the influence of TCM emotional nursing on emotions,size of skin lesions and psoriasis area and severity index (PASI)in patients with psoriasis vulgaris.Methods A total of 86 out-patients with psoriasis vulgaris from June 201 4 to August 2015 in Longgang District Central Hospital of Shenzhen were randomly divided into control group (43 cases,decoction for cooling blood +routine nursing)and experimental group (43 cases,decoction for cooling blood +TCM emotional nursing based on seven emotions) according to random number table method.Emotions and score of PASI were compared before and 6 weeks after intervention between two groups.Results After intervention,the score of PASI was (5.44 ±0.39)in experimental group which was significantly lower than that (6.53 ±0.29)in control group (P <0.05);the proportion of active stage,rest stage,catagen was 11 .63%,32.56%,55.81 % in experimental group which were better than those (20.93%,46.51 %,32.56%)in control group with significant differences (P <0.05);the score of compulsion, somatization,interpersonal relationship,depression,terror,anxiety and total score in experimental group were lower than those in control group with significant differences (P <0.05).Conclusions TCMemotional nursing based on seven emotions has an important significance on promoting rehabilitation,relieving clinical symptoms and negative emotions in patients with psoriasis.

Objective To investigate the expression of GLI1 and PTCH1 mRNA in pancreatic cancer and study its clinical significance. Methods Real-time fluorescence quantitative PCR (RFQ-PCR) was used to detect the expression of GLI1 and PTCH1 mRNA in 35 samples of pancreatic cancer tissues and 27 samples of adjacent normal pancreatic tissues, and the correlation of GLI1 and PTCH1 mRNA expression with clinical parameters was investigated. Results The relative expression of GLI1 mRNA in pancreatic cancer tissues was 1.12 ～ 3. 65 ( median 1.19), the relative expression of TCH1 mRNA was 1.82 ～ 4.36 ( median 2.36 ). The relative expression of GLI1 mRNA in adjacent normal pancreatic tissues was 0.23 ～ 2.76 ( median 0.87 ), the relative expression of PTCH1 mRNA was 1.11 ～ 2. 17 (median 0.58). Both the expression of GLI1 and PTCH1 mRNA in pancreatic cancer tissues were significantly higher than those in normal pancreatic tissues (P<0.05), and a positive correlation was found between GLIl and PTCH1 mRNA expression levels (P <0.05 ). The expression of GLI1 mRNA was significantly correlated with the differentiation degree and lymph node metastasis of pancreatic cancer (P < 0. 05). Conclusions GLI1 and PTCH1 may be involved in pancreatic carcinogenesis, and GLI1 may be related to invasion and lymph node metastasis of pancreatic cancer.

Objective To analyze the etiology in pancreatic pseudocyst (PPC). Methods Medical records were reviewed and analyzed for 366 PPC patients who were admitted in Changhai hospitals from April 2000 to December 2009 in terms. Demographic data, etiology and primary disorders of PPC patients were recorded.
