Objective: To investigate the current status of benefit finding among young and middle-aged patients with type 2 diabetes mellitus (T2DM) and analyze its influencing factors, so as to provide a reference for improving the level of benefit finding in this population. Methods: From November 2022 to May 2023, young and middle-aged patients with T2DM aged 18-59 years hospitalized in the endocrinology departments of 2 tertiary hospitals in Hengyang City, Hunan Province were selected as survey subjects by a convenience sampling method. Basic demographic information was collected using a general questionnaire survey. Benefit finding, resourcefulness, and stigma were evaluated using the Benefit Finding Scale, the Chinese Version of the Resourcefulness Scale, and the Type 2 Diabetes Stigma Assessment Scale, respectively. A multiple linear regression model was used to analyze the influencing factors of benefit finding among young and middle-aged patients with T2DM. Results: A total of 305 young and middle-aged patients with T2DM were investigated, including 222 males (72.79%) and 83 females (27.21%). There were 231 cases aged 45-59 years, accounting for 75.74%. The scores for benefit finding, resourcefulness, and stigma were (42.86±6.06), (75.12±11.30), and (41.20±10.10), respectively. Multiple linear regression analysis showed that young and middle-aged patients with T2DM who were male (β′=0.088), aged 18-<45 years (β′=0.083), absence of diabetes complications (β′=0.124), and had higher resourcefulness scores (β′=0.679) had higher levels of benefit finding, while patients with higher stigma scores (β′=-0.097) had lower levels of benefit finding. Conclusion The level of benefit finding among young and middle-aged patients with T2DM was moderate, and was related to gender, age, diabetes complications, resourcefulness, and stigma.

Interferon regulatory factor 1(IRF-1)is a member of the IRF family.It is the first transcription factor to be identified that could bind to the interferon-stimulated response element(ISRE)on the target gene and displays crucial roles in the interferon-induced signals and pathways.IRF-1,as an important medium,has all of the advantages of full cell cycle regulation,cell death signaling transduction,and reinforcing immune surveillance,which are well documented.Current studies indicate that IRF-1 is of vital importance to the occurrence and evolution of multifarious liver diseases,including but not limited to inhibiting the replication of the hepatitis virus(A/B/C/E),alleviating the progression of liver fibrosis,and aggravating hepatic ischemia-reperfusion injury(HIRI).The tumor suppression of IRF-1 is related to the clinical characteristics of liver cancer patients,which makes it a potential indicator for predicting the prognosis and recurrence of liver cancer;additionally,the latest studies have revealed other effects of IRF-1 such as protection against alcoholic/non-alcoholic fatty liver disease(AFLD/NAFLD),cholangiocarcinoma suppression,and uncommon traits in other liver diseases that had previously received little attention.Intriguingly,several compounds and drugs have featured a protective function in specific liver disease models in which there is significant involvement of the IRF-1 signal.In this paper,we hope to propose a prospective research basis upon which to help decipher translational medicine applications of IRF-1 in liver disease treatment.

OBJECTIVE: To review the development of adult and pediatric liver transplantation in Tianjin First Center Hospital, and to enhance academic exchanges, improve technological innovation, and jointly promote the progress and maturity in the field of liver transplantation. METHODS: The development of liver transplantation in Tianjin First Center Hospital was analyzed. The clinical data of adult and pediatric liver transplantation from September 1998 to September 2018 were collected. The important events and technological innovation achievements of liver transplantation during the 20 years were summarized. RESULTS: The first clinical liver transplantation was attempted in Tianjin First Central Hospital in April 1980. The first long-term survival adult liver transplantation in China was completed in 1994 (11 years survival after the operation). The specialized team of liver transplantation was formally established in September 1998. The 20-year clinical exploration and progress reflected the characteristics of era changes and technological innovation during the rapid development of liver transplantation in China. Our center performed liver re-transplantation in January 1999, reduced-size pediatric liver transplantation in August 2000. In May 2001, we organized the formulation for the preventive and treatment plan for hepatitis B recurrence after liver transplantation. We performed combined liver and kidney transplantation in July 2002, split liver transplantation (SLT) in April 2004, the first domino liver transplantation (DLT) in August 2005. Pediatric living donor liver transplantation (LDLT) was initiated in October 2006, adult LDLT was carried out in August 2007. In September 2007, the first living donor combined liver and kidney transplantation from the same donor in Asia was performed. The first domino+living donor double grafts liver transplantation in the world was performed in January 2009. In March 2011, we performed laparoscopically assisted right hepatic lobe liver transplantation (LDLT) with middle hepatic vein. In May 2014, living donor laparoscopic left lateral lobe procurement was successfully established. In April 2016, simultaneous liver, pancreas and kidney multi-organ transplantation was completed. Domino donor-auxiliary liver transplantation was performed in February 2017. In December 2017, extracorporeal membrane oxygenation (ECMO)-supported liver transplantation in a patient with severe pulmonary hypertension was successfully completed. Liver transplantation combined with partial splenectomy was established in April 2018. Cross-domino liver transplantation (hypersensitive kidney transplantation with auxiliary liver transplantation+pediatric liver transplantation) was performed in May 2018. During the 20 years, the team has performed or assisted other centers in Beijing, Shanghai, Guangzhou and Shenzhen to carry out more than 10 000 cases of liver transplantations. A total of 7 043 cases of various types of liver transplantation were performed in the single center of the hospital (6 005 adult liver transplantations and 1 038 pediatric liver transplantations). Concerning adult liver transplantation, the cumulative 1-year, 3-year and 5-year survival rate from September 1998 to March 2003 were 83.1%, 73.0% and 69.0%, from April 2003 to March 2009 were 85.3%, 76.2% and 72.1% and from April 2009 to September 2018 were 87.5%, 79.2% and 75.1%, respectively. The cumulative 1-year, 3-year and 5-year survival rate for pediatric liver transplantation were 93.5%, 92.2% and 90.2%, respectively. The nucleoside (acid) analogue combined with low dose hepatitis B immunoglobulin (HBIG) was developed to prevent the recurrence of hepatitis B after liver transplantation, this plan has reduced the recurrence rate of hepatitis B and the 5-year re-infection rate of hepatitis B virus (HBV) after liver transplantation significantly. The risk assessment system for tumor recurrence after liver transplantation was established and individual treatment method was established based on this assessment system. Continuous exploration and improvement of liver transplantation for liver cancer, liver re-transplantation, liver transplantation with portal vein thrombosis, SLT, DLT and multi-organ combined transplantation have significantly improved the clinical efficacy of patients and the post-operative survival rate. CONCLUSIONS The liver transplantation team of Tianjin First Center Hospital has carried out a scientific and technological exploration on the key problems and technical difficulties of clinical liver transplantation. This work strongly has initiated and promoted the rapid development of liver transplantation in China. The restrictive barrier of hepatitis B recurrence after liver transplantation has been overcome. The risk prevention and control system of tumor recurrence after liver transplantation has been established. A series of innovative achievements that can be popularized have been achieved in the field of complex liver transplantation and expansion of donor liver source. The iterative progress and sustainable development of liver transplantation have been realized.

Objective To analyze the treatment effect and factors affecting the prognosis in young people of papillary thyroid carcinoma (PTC).Methods A total of 69 PTC patients were reviewed retrospectively in Sun Yatsen University Cancer Center from Dec 1996 to Oct 2005.The prognostic status were compared using the Kaplan-Meier methods,the factors were analyzed by Log-rank test and the multiple factors were estimated by the Cox regression models.Results There were 26 males and 43 females.The median age was 24 years (mean:23.1 years).The average follow-up time was 113 months ranging from 73 to 174 months.20.3％ patients (14/69) experienced recurrence during follow-up time and 1.4％ patient (1/69) died.All the patients received levothyroxine after operation.The 10 year disease-free survival (DFS) rate of patients with or without extra thyroidal extension (ETE) of PTC was 29.6％ and 80.1％,respectively (P ＜ 0.01).Multivariate analysis showed that young PTC people with ETE had a worse prognosis (P =0.004).Conclusions Young papillary thyroid carcinoma patients had a favorable outcome.Surgical procedure was the first choice for this kind of patients.ETE was an independent factor for the recurrence of young PTC patients.

BACKGROUND:An ideal scaffold material needs appropriate degradation rate and certain mechanical properties, but the traditional colagen sponge scaffold has rapid degradation velocity and low mechanical strength, which is easy to colapse and difficult to maintain its natural form. Traditional cross-linking methods also have the problems of cytotoxicity or colagen denaturation, severely limiting the application of colagen. OBJECTIVE:To design a new cross-linking method for colagen and to optimize the self-assembly process so as to develop a colagen sponge scaffold with good mechanical properties and resistance to degradation. METHODS:Colagens were modified by self-assembly technology to prepare colagen fibrils which were then freeze-dried into fibrilar colagen sponges. Meanwhile, we optimized the conditions of self-assembly by using orthogonal experiment based on univariate analysis of the effect of initial colagen mass concentration, final phosphate concentration and pH value on the conversion yield of colagen self-assembly. RESULTS AND CONCLUSION:We optimized the conditions of self-assembly revealed that the optimum conditions to prepare colagen fibrils were determined as pH=8.0, initial colagen concentration=2 mg/mL, and final concentration of phosphate=15 mmol/L. The results of scanning electron microscope showed that fibrilar colagen sponges were characterized by refined porous structure which was connected by colagen fibrils. In addition, the fibrilar colagen sponges showed better equilibrium-sweling ratio, water retaining property and mechanical strength compared with unmodified colagen spondages (P < 0.05), to solve the problems in rapid degradation.

Objective To summarize our experience of harvesting and using the organs of donors after cardiac death.MethodsForm March 2010 to October 2011,56 potential donors were diagnosed with cardiac death,who conformed to the classification of Maastricht Ⅲ criteria.There were 40 failure cases whose family refused to donate,and one failure case who suffered from serious infection.Finally,the success ratio of donation after cardiac death was 26.8％ (15/56).Twelve livers and 22 kidneys were transplanted into 12 and 20 recipients respectively.ResultsTwelve cases of liver transplantations had acceptable outcomes. The grafts of 4 cases out of 20 cases of kidney transplantations were removed after transplantation,and other recipients had acceptable outcomes.ConclusionCitizens organ donation after cardiac death can expand the number of suitable organs,but we need to strictly control the criteria for potential donors.

ObjectiveTo summarize 20 ABO-incompatible liver transplantation cases in our hospital and explore the treatment strategy. MethodsFrom January 2009 to July 2011,20 cases donorrecipient ABO blood type not-identical liver transplantation was performed at our hospital. 16 cases were ABO-incompatible(ABO-Ⅰ) and 4 were ABO-compatible(ABO-C ).The median follow-up was (13.3 ± 9.2) months.ResultsExcept preoperative MELD score,there were no significant difference in other perioperative data,the incidence of postoperative complications and the cumulative survival rate between ABO-C and ABO-Ⅰ group.There were 5 deaths in 20 cases,2 cases in ABO-C group and 3 cases in ABO-Ⅰ group,survival rate was 75％.The cause of death was perioperative multiple organ failure in 2 cases,liver cancer recurrence in 2 cases and cerebral hemorrhage in 1 case.There were 2 cases of acute rejection,3 cases of biliary complications and 3 cases of portal vein thrombosis developing postoperatively. Eleven patients had increased serum creatinine after operation,preoperative high creatinine existed in 6 cases and it maintained posttransplant high level for more than 7 days,the serum creatinine level in other 7 patients was back to normal level in 7 days.ConclusionsA combination splenectomy before the portal vein reperfusion,the protocol of basiliximab,tacrolimus (TAC)/mycophenolate mofetil (MMF)/steroids immunosuppression treatment,postoperative peripheral vascular dilatation treatment by Alprostadil,help achieve favorable outcome in selected patients who underwent ABO-incompatible liver transplant.

Objective To study the prognosis of patients with end-stage liver cirrhosis who using controlled cardiac death liver donor in situ liver transplantation. Methods Seven cases of transplants which used liver donated after cardiac death were done in our center. The preoperative and postoperative data were analyzed. The prognosis of these patients was observed. Results Except one recipient died of upper gastrointestinal bleeding at the 9th day after surgery, the remaining 6 patients were followed up for more than 12 months (mean 15.7 months) and the prognosis was satisfactory.Conclusion Patients can get good prognosis after the liver transplants with donated liver after cardiac death which meets the Maastricht Classification type Ⅲ.
