Objectives To investigate the results of liver transplantation using steatosis liver donors in order to provide a scientific basis for the use of marginal donors.Methods From 2002 to 2011,80 of 407 were steatosis liver donors.There were 69 males and 11 females.Their age ranged from 20-54 years old.Sixteen donor livers with severe fatty liver and reperfusion injury were not used.The remaining 64 livers were divided into a S1 group (mild steatosis,n=22),a S2 group (moderate steatosis,n=25),and a S3 group (severe steatosis,n=17).A S0 group was used as a control (randomly selected fat-free liver,n=80).Results The occurrence rates of delayed graft function (DGF) in the S0,S1,S2,S3 groups were 5％,9.1％,20％,29.41％,respectively.Primary nonfunctioning occurred in 2 cases of the S3 group,which represented a 11.76％ of the S3 group (2/17),and 3.12％ of the total 64 cases (2/64).Conclusions Although the incidence rate of DGF was higher in the steatosis liver donor groups than the S0 group,there was no correlation in the mortality rate of the S1-S3 group within one year of transplantation.Attentions should be paid to the treatment of complications after steatosis liver transplantation.By minimizing ischemia-reperfusion injury,improving microcirculation,strengthening routine therapy and reducing the amount of immunosuppression,the same results could be achieved using steatosis donor liver and normal liver for transplantation.

Objective To investigate the change of umbilical cord blood gas from early-stage neonates with pregnancy-induced hypertension syndrome (PHIS) affected mothers and its influence upon internal environment of body,and to evaluate the significance of postpartum umbilical cord blood gas analysis.Methods Retrospective study of 101 neonates(born of 97 PHIS-affected mothers),41 cases of mild group,34 cases of moderate group,26 cases of severe group,and enrolled 52 neonates born of non-PHIS mothers as the control group.Prior to neonate's first breath,umbilical cord artery blood gas analysis was performedimmediately to determine the values of pH,arterial carbon dioxide partial pressure (PaCO2),arterial oxygen tension (PaO2),HCO3-,base excess (BE),and Apgar score was completed within 1 min after birth.Results The pH,PaO2,HCO3-,BE in severe group was significantly lower than those in mild group,moderate group,and control group [7.16 ± 0.18 vs.7.25 ± 0.09,7.22 ± 0.11,7.29 ± 0.08 ; (12.01 ± 2.75) mmHg (1 mmHg =0.133 kPa) vs.(18.35 ± 1.75),(14.21 ± 2.01),(22.23 ± 1.45) mmHg; (17.11 ± 2.42) mmoFL vs.(19.82 ±3.85),(17.32 ± 3.21),(22.56 ± 3.38) mmol/L; (-9.15 ± 0.32) mmol/L vs.(-7.95 ± 0.60),(-7.21 ± 0.08),(-6.76 ± 0.03) mmol/L] (P ＜ 0.05),the PaCO2 in severe group was significantly higher than that in mild group,moderate group,and control group [(61.84 ± 32.93) mmHg vs.(54.48 ± 12.82),(58.38 ± 15.32),(51.66 ± 10.52) mmHg] (P ＜ 0.05),Apgar score 1 min after birth was positively correlated with umbilical arterial pH (P ＜ 0.05),the lower Apgar score,the lower pH.Among 65 cases of Apgar score ≤ 7 scores,37 cases of acidosis (pH ＜ 7.20),the incidence rate was 56.92％ (37/65) ; among 88 cases of Apgar score ≥ 8 scores,11 cases of acidosis,the incidence rate was 12.50％ (11/88),the difference was statistically significant (P ＜ 0.01).Conclusions Umbilical cord blood gas analysis is more objective than Apgar score,which could reflect neonate's hypoxia-ischemia degree bore of PIHS mothers,as well as contributed to the assessment of neonate' s prognosis.Conventional umbilical cord blood gas analysis is necessary for neonates bore of PIHS-affected mothers.Enhanced monitoring should be performed in a timely manner on those neonates born after intrauterine distress signs or with low Apgar score,the prevention and therapy as early as possible can improve the quality of birth.

Objective To compare SPECT/CT fusion imaging and MRI in the diagnosis of benign hip lesions. Methods Twenty-two patients suspected avascular necrosis of femoral head with hip discomfort, pain or action limited were analyzed retrospectively. All patients underwent radionuclide bone scan and MR examination within 5 days, and the diagnosis was proved with clinical follow-up. Results Eighteen necrosis of the femoral head and 4 hip arthritis including 1 patient with ankylosing spondylitis were found in 44 hip joints of 22 patients. MRI detected 17 femoral head necrosis and 4 hip arthritis, while SPECT/CT fusion image found out 18 femoral head necrosis and 4 hip arthritis. There was corresponding relationship in signs of hip lesions between MRI and SPECT/CT fusion imaging. Conclusion SPECT/CT fusion imaging and MRI has no markedly difference in the diagnosis of hip benign lesions, and is complementary to each other. SPECT/CT fusion image can distinguish the hip lesions from the femoral head lesions, and has a higher accuracy of diagnosing hip lesions than whole body bone scanning.

OBJECTIVETo establish the method of promoting human peripheral blood mononuclear cell proliferation by polysaccharide of snakegourd root and identify the effects of polysaccharide of snakegourd root on lymphocyte proliferation, T lymphocyte subsets and the different levels of TNF-alpha and IL-6.

METHODThe polysaccharide of snakegourd root preparations were purified with dialysis and ethanol precipitation. The healthy human PBMC were used as the target cells for screening potency of the drugs. MTT colorimetry was established to examine the levels of lymphocyte proliferation on human PBMC by polysaccharide of snakegourd root in vitro. The percents of lymphocyte subsets (CD3+, CD4+, CD8+ T lymphocyte) and the different levels of TNF-a and IL-6 in PBMC were analysed by FCM and ELISA, respectively.

RESULT1.0-50.0 mmol x L(-1) of polysaccharides of snakegourd root showed the significant effects of promoting proliferation of human PBMC (P < 0.05). The percents of CD3+, CD4+, CD8+ T lymphocytes in PBMC treated with 5.0 and 10.0 mmol x L(-1) of polysaccharides of snakegourd root were significantly higher than those of the control group (P < 0.05). The levels of TNF-alpha and IL-6 were significantly higher than those of the control group after 1.0, 5.0, 10.0 mmol x L(-1) of polysaccharides of snakegourd root stimulation on the human PBMC at 8 hours (P < 0.05).

CONCLUSIONThe significant effects on promoting lymphocyte proliferation and activation of the polysaccharide of snakegourd root are confirmed in this study. The percents of lymphocyte subsets are increased in different degrees by the polysaccharide of snakegourd root. The high levels of TNF-alpha and IL-6 are secreted after the polysaccharides of snakegourd root stimulation on the human PBMC, which lays a foundation for further elucidating the immunocompetence effects and mechanism of the polysaccharide of snakegourd root.

Objective To compare three different types of donor livers (C-Ⅰ,C-Ⅱ,C-Ⅲ) in clinical efficacy,complications and survival rate of liver transplantation.Methods Using the retrospective descriptive study method,the clinical data of 422 patients undergoing liver transplantation,including 124 cases of C-Ⅰ,81 cases of C-Ⅱ and 81 cases of C-Ⅲ in recent 6 years (from June 2010 to June 2016) were analyzed.The same surgical method was performed with piggyback liver transplantation.Observation indicators contained (1) recipient postoperative liver function;(2) the postoperative complications;(3) the recipient survival rate.SPSS 19.0 statistical software was used for analysis.Results (1) The curative effect was evaluated by the changes of ALT and TBIL among three groups of recipients postoperatively.As compared with C-Ⅰ transplantation group and CⅢ transplantation group,the level of ALT in C-Ⅱ transplantation group was significantly increased (P ＜0.05),the clinical efficacy was poorer.(2) The incidence of PNF was 3.23％ in C-Ⅰ group,9.88％ in C-Ⅱ group and 9.88％ in C-Ⅲ group (P＜0.05).The incidence of acute rejection was respectively 9.68％ in C-Ⅰ group,38.27％ in C-Ⅱ group and 38.27％ in C-Ⅲ group (P＜0.001).The incidence of SIRS was respectively 5.65％ in C-Ⅰ group,39.50％ in C-Ⅱ group and 39.50％ in C-Ⅲ group (P＜ 0.001).There were significant differences in the incidence of other complications among the three groups.(3) There were 14 deaths within 3 months,accounting for 17.28％,and the survival rate was 82.72％ in C-Ⅱ group,the 1-,3-,and 5-year survival rate was 76.55％,74.18％ and 76.55％ respectively in C-Ⅰ group,and that was 88.02％,85.72％ and 81.11％ respectively in C-Ⅲ group.Conclusion Since June 2015,C-Ⅰ donors grow up more quickly on year-on-year basis than C-Ⅱ.Simultaneously,the sort-term and long-term clinical efficacy is better in C-Ⅰ transplantation group than in C-Ⅱ transplantation group.How to repair the three types of Chinese standard donor organs and optimize the quality is still a hot point to ensure the healthy development of organ transplantation in China,which needs further investigation.

Objective:To explore the mediating effect of perceived professional benefits between the humanistic literacy and spiritual care competence among oncology nurses.Methods:From September to October 2022, convenience sampling was used to select 354 oncology nurses from 11 ClassⅢ Grade A hospitals in Sichuan Province, Guangdong Province, and Hubei Province as the research subject. A survey was conducted on oncology nurses using the General Information Questionnaire, Nurses' Perceived Professional Benefit Questionnaire, Nurses' Humanistic Literacy Scale, and the Chinese version of the Spiritual Care Competence Scale (SCCS) . Pearson correlation was used to analyze the relationship between nurses' humanistic literacy, perceived professional benefits, and spiritual care competence. AMOS 26.0 software was used to analyze mediating effects. A total of 354 questionnaires were distributed, and after excluding 7 unqualified questionnaires, 347 valid questionnaires were collected, with a valid response rate of 98.02%.Results:Among 347 oncology nurses, the score of the Chinese version of SCCS was (77.60±19.04) . The total score of the SCCS was positively correlated with the total scores of the Nurses' Humanistic Literacy Scale, the Nurses' Perceived Professional Benefit Questionnaire, and scores of all dimensions, with statistically significant differences ( P<0.01) . Bootstrap test showed that the mediating effect of perceived professional benefits among oncology nurses between humanistic literacy and spiritual care competence was 0.284 [95% CI (0.408, 0.860) ] , accounting for 50.90% of the total effect. Conclusions:The perceived professional benefits of oncology nurses play a partial mediating role between humanistic literacy and spiritual care competence. We should strengthen training on the humanistic literacy of oncology nurses, enhance their perceived professional benefits, form a virtuous cycle of employment, and thereby improve their spiritual care competence.
