Objective:To investigate the efficacy and safety of plasma exchange (PE) combined with plasma perfusion (PP) in treatment of liver failure and the influence on inflammatory factors and liver function.Methods:98 patients with liver failure in our hospital from February 2014 to February 2016 were selected as the subjectswere,and they were randomly divided into experimental group and control group,and each group was 49 cases.The experimental group was treated with PE combined with PP,and the control group was received PE alone.The liver function before and after treatment was detected by automatic biochemical analyzer.The serum levels of C-reactive protein (CRP),tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) were determined by enzyme-linked immunosorbent assay (ELISA).The total effective rate,the incidence of side effects,the levels of liver function and inflammatory factors before and after treatment were compared between the two groups.Results:The clinical effective rate in the experimental group (91.84％) was significantly higher than that in the control group (73.47％),the difference was statistically significant (P＜0.05).The incidence of adverse reactions in the experimental group (10.20％) was significantly lower than that in the control group (38.78％),the difference was statistically significant (P＜0.05).The levels of serum alanine aminotransferase (ALT),total bilirubin (TBIL) and blood ammonia (NH3) were significantly decreased in both groups after treatment (all P＜0.05).Albumin (ALB) and thrombin activity (PTA) were significantly increased in both groups after treatment (both P＜0.05).After treatment,the serum levels of ALT,TBIL and NH3 in the experimental group were lower than those in the control group (all P＜0.05),the levels of ALB and PTA were higher than those of the control group,the difference was statistically significant (both P＜0.05).After treatment,the serum levels ofCRP,TNF-α and IL-6 were lower than those before treatment,and the serum levels of CRP,TNF-α and IL-6 in the experimental group were lower than those in the control group (all P＜0.05).Conclusion:The combination of plasma exchange and plasma perfusion has a good effect in the treatment of liver failure,and the incidence of adverse reactions is low.It can effectively remove inflammatory factors,improve liver function and improve the quality of life of patients.

Objective To observe the differentiation of bone marrow multipotent adult progenitor cells(MAPCs)into skin tissue cells of rats in vivo. Methods Magnetic activated cell sorting (MACS)was used to remove MAPCs from bone marrow of male rats through negative screening.Tail vein injection with combined with MAPCs Was done in C57BL/6 mice with skin wound and nude mice with immunodeficieney.Immunohistochemical staining was used to examine the expression of MHCI antigen in the healed skin of donor SD rats. Results Positive MHCI cells were found in the epidermal fundus and Some hair follicle-like structures of the healed skin of C57BL/6 mice.Hair follicle-like structure appeared in the healed skin of nude mice group,in which positive MHCI cells were found in the basal epidermal and some hair follicle-like structures. Conclusions During skin damage,MAPCs can migrate to the injured skin area and skin adnexa hair foilicle area,transform into epidermal cells and hence participate in the healing of the wound skin.

Objective To explore the evolution of research themes and trends in China's nursing college education during the last decade.Methods A co-word analysis of keywords was performed in the research literatures around nursing college education from two Chinese databases,VIP China Science and Technology Journal Database and CKNI Periodical Full-text Database,between 2003 and 2012.The analysis was based on two different periods (phase Ⅰ from 2003 to 2007 and phase Ⅱ from 2008 to 2012).Results A total of 646 articles were included,with 287 articles published in phase Ⅰ and 359 articles in phase Ⅱ.Sixteen high-frequency keywords were identified during the phase Ⅰ,with seventeen during the phase Ⅱ.Two research themes,nursing student-training model and construction and reform of curriculum,were presented in both phases.However,some differences in research sub-themes exited between phase Ⅰ and phase Ⅱ.Conclusions Hot research topics in nursing college education seemed no change in the past ten years.School-hospital collaboration newly emerged as a hot topic in the field of nurse education research.The research on construction and reform of curriculum change its focus to nursing courses and humanities courses.The academic studies of nursing college education were mostly influenced and pushed by reforming and developing of nursing education.

Objective To determine the effecting factors for diagnosis of binign or malignant in cystic lesions of pancreas(CLP).Methods One hundred twenty-six patients undergoing operations for CLP or suspected CLP in this hospital from January 1984 to June 2008 were reviewed.Patients were divided into two groups according to lesion's histological features after operation.The predictive effect of various preoperative factors on the malignant potential of CLP was evaluated.Results One hundred twenty-six patients underwent operations for suspected pancreatic cystic neoplasms.There were 89 benign and 37 malignant CLPs.The univariate analysis showed that gender, clinical symptoms(jaundice and weight loss), elevated serum CA199, and presence of one or more of three morphologic features such as solid component, nodule or septation were significantly different between benign and malignant cystic neoplasm of pancreas.The multivariate analysis indicated that imaging features and gender were independent predictors of malignancy.Conclusion In patients with suspected pancreatic cystic neoplasms, elevated serum CA199, clinical symptoms(jaundice and weight loss)and presence of suspicious morphologic features on imaging are predictors of malignant potential of CLP.Patients with a high likelihood of a potentially malignant or malignant lesion based on these three factors should undergo operation without additional investigations.

Objective: To deepen the knowledge of HIV-negative plasmablastic lymphoma (PBL) . Methods: Medical records from 8 HIV-negative PBL patients diagnosed in Peking Union Medical College Hospital from January 1997 to May 2015 were collected, and the clinical features and prognosis of these patients were analyzed. Results: All of these 8 patients were diagnosed as HIV-negative PBL, 3 of 8 patients were males, and others were female. The median age was 60 (43-80) year. Among these patients, 4 cases had underlying immunosuppressive state. These patients all had extra-nodular involvement, and 6 cases of them were at stage Ⅳ according to Ann Arbor Staging, 5 patients had bone marrow involvement. CD38 and CD138 were diffusely positive for all patients, while the positive rate of B cell marker including PAX-5 and Bcl-6 were relative low. 5 of 8 patients had been detected for EBV-DNA, and all of them were negative. The median follow-up for the 7 patients receiving chemotherapy and regular follow-ups was 36 (11-57) months, the median progression-free survival (PFS) was 15 (6-52) months, and the median overall survival was 36 (2-52) months. Among these patients, 4 cases had received chemotherapy combined with Bortezomib, showing 3 cases of effective, but it seems to be difficult to keep the long term efficacy, and disease progression occurred in 2, 9, and 21 months after treatment. 2 patients at stageⅠ-Ⅱ were treated effectively, without disease progression and survival, 5 patients at stage Ⅳacquired the efficacy unsustainably, with a median PFS of 10 (2-21) months and a median overall survival of 12 (6-52) months. Conclusion HIV-negative PBL is relatively prevalent in elderly patients, and presenting with high invasiveness in clinical, extremely prone to extra-nodular involvement, especially the bone marrow. The immunophenotype of PBL is more resemble to that of plasmacytoma. Patients who were in late stage at diagnosis show poor prognosis.

Objective To summarize the diagnostic and therapeutic experiences for multiple insulinoma. Methods Clinical data of 34 cKsefl of multiple insulinoma treated in Peking Union Medical College Hospital between 1984 and 2007 were analyzed retrospectively. Results Multiple insulinoma was identified in these 34 cases for 37 instances.Malignant insulinoma was found in 2 cases.Three cases suffered from postoperative recurrent multipie tumors.35.3% cases belonged to MEN1;13.5% cases were of insulinoma combined with islet hyperplasia;43.2% cases had 3 or more than 3 insulinomas;Fifteen cases (40.5%)had had a misdiagnosis.45.2%tumors were smaller than 1 cm in diameter:88.9%multiple insulinonla located at the body and tail of the pancreas.Enucleation of multiple tumors was performed for 48.7 percent of cases. Conclusions Most multiple insulinomas were small,it was difficult for preoperative examination to locate all the tumors therefore.Being on the alert against multiple insulinoma and such measures as careful exploration,intraoperative blood glucose determination.fine needle aspiration biopsy,frozen sections helps to avoid missing multiple imuhnoma.

Objective: To explore the effect of enterostomy on analgesic pattern in advanced digestive tract cancer. Methods: A retrospective cohort study was carried out, which was approved by the Ethics Committee of the Sixth Affiliated Hospital of Sun Yat-sen University (E2018026). Inclusion criteria were as follows: (1)age and gender were not limited; (2) all the gastrointestinal malignancies were confirmed histologically, and local recurrence or metastasis were confirmed by CT or MR; (3) numerical rating scale (NRS) ≥4 points, opioid analgesic drugs were required; (4) informed consents were signed by patients of their own. Exclusion criteria were as follows: (1) malignancies of early stage; (2) suspicious adverse mental states which might lead to poor administration compliance; (3) hypersensitivity or allergic reactions to opioids. Clinical data of patients with advanced gastrointestinal cancer receiving comprehensive treatment at the Medical Oncology Department of the Sixth Affiliated Hospital of Sun Yat-sen University from September 2016 to April 2017 were retrospectively collected. The patients were divided into the stoma group and the non-stoma group. The clinical findings of two groups were analyzed, including age, sex, ostomy status, pain location, presence or absence of intestinal obstruction, pain characteristics, selection of opioid analgesic agents, treatment of side effects of analgesics. Pain was assessed using brief pain inventory(BPI) table and NRS score. Strong opioids were prescribed for patients of NRS ≥4. Patients who were intolerant to opioids required opioid titration. The titration drugs included oral or IV morphine and oxycodone. After achievement of adequate pain control, long-acting opioids were administered, which included sustained-release morphine tablets, controlled release oxycodone and transdermal fentanyl. Criteria for pain relief included NRS≤3, breakthrough pain <3 times/day and duration of adequate pain control >3 days. The χ² test and the Wilcoxon signed rank sum test (nonparametric test) were used to analyze the clinical features of patients in the stoma and non-stomach groups. In order to find the factors associated with maintenance therapy and the use of laxatives, the variables were compared as well as in multivariate analysis with multiple regression models. For all the statistical tests, a value of P<0.05 in a two-tailed test was established as the alpha significance level. Result: A total of 123 patients were enrolled in this study, including 79 males (64.2%) and 44 females (35.8%) with a median age of 51 years. Fifty-two patients were in stoma group, including 30 (24.4%) of ileostomy and 22 (17.9%) of colostomy, and 71 patients were in non-stoma group. Pain of 40 (76.9%) patients in stoma group located in abdomenopelvic site while the pain of 44 (62.0%) patients in non-stoma group located in other sites. Compared with non-stoma group, cases in stoma group complained more abdominopelvic pain (73% vs. 62.0%, P<0.001).The median NRS pain score before treatment in the stoma group and the non-stoma group was 5.7 and 5.6, respectively, without statistically significant difference (P=0.741). After analgesic management, the above scores reduced to 2.1 and 2.3, respectively, without statistically significant difference as well (P=0.092). Analgesic treatment was effective in 111 cases (90.2%), including 49 cases (94.2%) in the stoma group, and 62 cases (87.3%) in the non-stoma group, and there was no statistically significant difference between the two groups (P=0.202). There was more application of fentanyl transdermal patch [34.6%(18/52) vs. 9.8%(7/71)] in the stoma group, while more application of lactulose laxative [78.9%(56/71) vs. 61.5%(32/52)](χ²=10.023, P=0.002) in the non-stoma group. Multivariate analysis revealed that ostomy (OR=0.290, 95%CI: 0.102-0.824, P=0.009) and pain site (OR=5.691, 95%CI:1.709-18.948, P=0.005) were independent factors affecting the choice of the first line opioid sustained release agent. Of the 123 patients with maintaining analgesia, 98 had available data of laxative use, of whom 46 used laxatives to prevent or treat constipation, and the proportion of laxatives in stoma group (21.2%, 11/52) was significantly lower than that in non-stoma group (49.3%, 35/71) (χ²=6.957, P=0.008). Multivariate analysis of the application of laxative use showed that age (OR=0.281, 95% CI: 0.123-0.684, P=0.010) and ostomy (OR=2.621, 95% CI: 1.033-6.687, P=0.045) were independent factors affecting the use of lactulose laxatives. Conclusions Enterostomy may affect the analgesic pattern in advanced digestive tract cancer. Patients with stoma are more likely to use fentanyl transdermal patches and younger patients with stoma do not need prophylactic use of laxatives.
