Objective To summarize the clinical experience of diagnosis and treatment of nontuberculosismycobacterium (NTM) infection after liver transplantation. Methods Clinical experience of effective treatment of 1 case with NTM at 7th month after liver transplantation at the Shanghai Changzheng Hospital affiliated to the Second Military Medical University was summarized and literature review was performed. Results Following liver transplantation, the NTMpatient was clinically manifested with fever in the afternoon. CT scan prompted the progression of the disease. The lesions were enlarged and fused with thin-walled cavity in the right upper lung. The diagnosis of NTM infection was validated by fiberoptic bronchoscopy (brush or lavage approach), spot test of T cells infected with mycobacterium tuberculosis (T-SPOT. TB), multiple phlegm culture and empirical anti-tuberculosis therapy. The patient was effectively treated and successfullydischarged after diagnostic quadruple anti-tuberculosis therapy. The patient was followed up until the day of manuscript submission. The patient was physically stable without the symptoms of fever and cough with asthma. The liver function was normal. Conclusions The incidence of NTM infection is rare and inneglectable after liver transplantation. Application of fibrobronchoscopy via brush or lavage approach can enhance the positive diagnostic rate. Diagnostic quadruple antituberculosis therapy is efficacious for NTM infection.

Objective To investigate the clinical effect of liver transplantation in the treatment of hepatolenticular degeneration (HLD) and the prognosis of HLD patients.Methods A retrospective analysis was performed for the clinical data of 15 HLD patients who underwent liver transplantation in Changzheng Hospital of Second Military Medical University from June 2003 to January 2017.Friedman test of K related samples test was used for comparison of data between groups,and Wilcoxon one-sample test of 2 related samples test was used for comparison of data between two groups.Results Of all patients,13 underwent standard orthotopic liver transplantation,and 2 underwent modified piggyback liver transplantation.One patient died of multiple organ failure during the perioperative period and 2 were lost to follow-up at half a year after surgery.Of all patients,one lived for 14 months,one lived for 5 years and 8 months,and the other ten patients were still alive up to now.Six patients suffered from acute rejection reaction (AR),among whom four were improved after conventional hormone pulse therapy,one was improved and discharged after antiviral therapy with ganciclovir for cytomegalovirus infection,and the other one patient was improved and discharged after the second liver transplantation at 5 months after surgery due to poor response to hormone pulse therapy and chronic rejection reaction.Ten patients had varying degrees of improvement in positive Kayser-Fleischer ring,and three patients achieved varying degrees of improvement in severe neuropsychiatric symptoms and had a basically normal neuropsychiatric state at half a year to one year after surgery.One patient died in the perioperative period,and the other 14 patients had a significant improvement in liver function at 1 month after surgery,and the level of ceruloplasmin gradually increased to a normal level.Conclusion Orthotopic liver transplantation can effectively improve copper metabolism,liver function,and neuropsychiatric symptoms in HLD patients and increase their quality of life and long-term survival rates.

Colorectal cancer has been one of the leading malignancies with a high incidence and a great mortality in the world, Liver is the most common site of metastases.For nonresectable colorectal liver metastases(nrCRLM), no palliative therapy brings any change of terminal death.With limited sample sizes but long enough follow-ups, a series of clinical trials have confirmed that selected nrCRLM patients may be cured by liver transplantation(LT). However, there are great challenges of donor shortage, recipient criteria and high recurrence rate after LT.For promoting the curative effect and quality control, the authors elaborated upon various major issues of LT for nrCRLM, including non-resectability of colorectal liver metastases, chemotherapy-associated liver injuries, prognostic factors, surgical approaches and post-transplant therapies.

Objective To understand the status quo of midwives' core competency in Fujian Province and analyze its influencing factors.Methods A total of 374 midwives from 13 hospitals in Fujian Province were surveyed by the midwife core competency scale.Results The average score of midwives' core competency were(3.96±0.54).The scores of vocational literacy,postnatal care skills and health care skills during pregnancy were relatively high.The scores of public health care knowledge,public health care skills and women's health knowledge were relatively low.The scores of core competence for junior,senior and expert abilities for midwives were (4.03±0.55),(3.78±0.59)and (3.54±0.75),respectively.In seven dimensions,the scores for skills were all higher than those for knowledge.Multivariate stepwise regression analysis showed that years of working,hospital grade,marital status and form of employment were influencing factors of midwives' core competency (P＜0.05).Conclusion The core competence of midwives in 13 hospitals in Fujian Province was generally at the middle level.The junior ability was satisfactory,and the senior and expert abilities should be improved.Midwives who were newly employed,working in primary institutes,non-institution personnels should be paid more attention in order to promote midwives' core competency holistically.

Objective To study liver transplantation in the treatment of alcoholic liver disease (ALD).Methods A retrospective study was conducted on 40 patients with ALD who underwent liver transplantation in the Changzheng Hospital of the Second Military Medical University from April 2005 to June 2017.The data were expressed as mean ± standard deviation ((-x) ±s) in populations with a normal distribution,and as median (min～max) in populations with an abnormal distribution.The survival rate was analyzed by life tables,and the Cox regression analysis was used for multivariate analysis.Results All patients were followed up until August 31,2017.The follow-up time was 2 ～ 4518 days,with a median of 997 days.Among the 40 patients,8 had already died (3 died of multiple organ failure,2 of biliary complications,1 of liver failure,1 of sepsis and 1 of recurrence of hepatocellular carcinoma (HCC).The 1-year survival rate was 81.0％,and the 5-year survival rate was 77.0％.Four of 40 patients developed tumor recurrence.The initial recurrence time was 189 ～ 337 days (median 236.5).The recurrence sites included the liver,colon combined with lungs,lungs,and lumbar vertebrae.Six of 40 (15.0％) patients had relapse in alcoholism.Multivariate analysis showed that age was a prognostic factor (RR =1.109,P ＜0.05).Years of drinking,daily amount of alcohol intake,abstinence,a previous history of upper gastrointestinal bleeding,a previous history of splenectomy,co-existing hepatocellular carcinoma,preoperative MELD score,preoperative Child-Pugh score,total operation time,anhepatic period,cold ischemia time,amount of intraoperative bleeding,postoperative alcoholism relapse,tumor recurrence or new onset of tumor were not significantly correlated with the postoperative survival rate (P＞0.05).Conclusions ALD patients were mostly 40 ～ 60 years old.Age was an independent factor affecting survival.The younger the patient,the better the prognosis.Other factors were of no prognostic significance.

Objective: To evaluate the vitamin D nutritional status in Chinese women of child-bearing age by analyzing serum 25-hydroxyvitamin D level in 2010-2012. Methods: Data were obtained from the China Nutrition and Health Survey in 2010-2012. Using cluster sampling and proportional stratified random sampling, 1 514 women of child-bearing age (18-44 years old) from 34 metropolis and 41 small and medium-sized cities were included in this study. Demographic information was collected by questionnaire and serum 25-hydroxyvitamin D concentration was determined by radioimmunoassay, in accordance with the 2010 Institute of Medicine of the National Academies standards. We compared differences in vitamin D levels, specifically serious deficiency, lack of deficiency, insufficiency, and excess. Results: The overall serum 25-hydroxyvitamin D level of Chinese urban women of child-bearing age (P₅₀ (P₂₅-P₇₅)) was 20.1 (15.1-26.3) ng/ml; minorities had a significantly higher serum 25-hydroxyvitamin D level of 22.0 (15.9-27.5) ng/ml compared with women of Han nationality (19.8 (14.9-26.2) ng/ml) (χ²=7.02, P=0.008). The proportions of women with serious deficiency, lack of deficiency, insufficiency, and excess vitamin D were 11.6% (n=175), 37.9% (n=574), 35.1% (n=531), and 0.3% (n=5), respectively. Only 15.1% (n=229) of women of child-bearing age had normal vitamin D nutritional status. No significant differences in vitamin D nutritional status were observed according to age, body mass index, city, nationality, educational level, marital status, or household income per capita (P>0.05). Conclusion Most Chinese urban women of child-bearing age have poor vitamin D levels and require vitamin D supplementation.

Objective To summarize our experience in the diagnosis and treatment of hepatic epithelioid angiomyolipoma (HEAML),with the aim to reduce the future misdiagnosis rate.Methods The PubMed,Medline,China Science Periodical Database (CSPD),and VIP Databases were searched from January 2000 to March 2018 on all reports on HEAML.Results There were 409 cases of HEAML in 97 reports.The ratio of men to women was 1∶4.84.The age ranged from 12 to 80 years and the median age was 44 years.61.9％ of patients (205/331) were asymptomatic,while 34.7％ (115/331) had upper or right upper quadrant abdominal discomfort.Some patients presented with abdominal mass,gastrointestinal reaction,low grade fever or weight loss.The clinical symptoms in 78 patients were not mentioned in the reports.The misdiagnostic rate of HEAML was as high as 40.3％ (165/409).The imaging findings of HEAML were nonspecific.Ultrasound,CT and MRI scan usually showed contrast enhancement in the arterial phase.Most lesions were accompanied by central vessels with early drainage veins.The enhanced scans showed varied characteristics.The ratios of fast wash-in and fast wash-out,to fast wash-in and slow wash-out,and to delayed enhancement were roughly 4∶ 5∶ 1.A definitive diagnosis of HEAML is based on the pathological findings of epithelioid cells in the lesions and the expressions of HMB45,SMA,Melan-A and Actin on immunohistochemical staining.HEAML had a relatively low malignant rate of 3.9％.Surgical resection was the main treatment for HEAML.Conclusion HEAML was a rare and easily misdiagnosed disease.,which could be diagnosed by taking into account the clinical course,imaging,pathological and immunohistochemical findings.HEAML.

Since the 1970s， patients with chronic pancreatitis （CP） have benefited from total pancreatectomy with autologous islet cell transplantation （TPAIT）. With the continuous development of surgical techniques and perioperative management over the past few decades， there have been improvements in islet cell function， insulin independence rate， and the survival rate of patients. This article summarizes the preoperative indications for TPAIT， the development of surgical operations， postoperative management and monitoring， and prognosis， so as to help clinicians learn more about TPAIT.

With persistent breakthrough and maturity of surgical procedures and postoperative immunosuppressive therapy, the survival rate of liver transplant recipients and grafts has been significantly increased. The shortage of donor liver has become the main obstacle for clinical development of liver transplantation. How to expand the source of donor liver has become an urgent issue. Groundbreaking progresses have been made in the use of common marginal donor livers in clinical liver transplantation, such as elderly donor liver, steatosis donor liver, viral hepatitis donor liver and liver from donation after cardiac death. Nevertheless, multiple restrictions still exist regarding the use of marginal donor liver. Consequently, the definition of marginal donor liver and research progress in the application of common marginal donor livers were reviewed, and the opportunities and challenges of mariginal donoor liver were illustrated, aiming to provide reference for expanding the donor pool for clinical liver transplantation and bringing benefits to more patients with end-stage liver disease.
