Objective:To study the impact of early blood concentrations of tacrolimus on the survival of patients after liver transplantation.Methods:Clinical data of 159 patients with liver diseases undergoing classic orthotopic liver transplantation at the Department of Hepatobiliary Surgery, the 900th Hospital of the Joint Logistics Support Force between January 2010 and December 2019 were retrospectively analyzed, including 123 males and 36 females, aged (48.0±12.2) years. According to survival status, patients were divided into the surviving group ( n=108) and death group ( n=51). Inverse probability of treatment weighting (IPTW) was applied to adjust for confounding factors by weighting covariates between the two groups. Univariate and multivariate Cox regression analysis were used to examine the relationship between early tacrolimus concentrations and mortality, and restrict cubic spline (RCS) curves were employed to assess the nonlinear relationship further. Results:After IPTW weighting, multivariate Cox regression analysis indicated that early tacrolimus concentration ( HR=2.479, 95% CI: 1.354-4.537, P<0.001) and preoperative international normalized ratio ( HR=0.358, 95% CI: 0.162-0.792, P=0.011) levels were risk factors for post-transplant survival. The RCS curve revealed that the optimal thresholds for early tacrolimus concentration were 6.30 ng/ml and 8.28 ng/ml ( P<0.001). Patients were therefore divided into the optimal concentration group ( n=60) and the non-optimal concentration group ( n=99). After IPTW weighting, the optimal concentration group comprised 102 cases, and the non-optimal concentration group included 212 cases. The 1-year, 3-year and 5-year survival rates in the optimal concentration group and the non-optimal concentration group were 97.06%, 81.37% and 75.49%, and 86.32%, 64.62% and 50.94%, respecitvely ( χ2=8.37, P<0.001). Conclusion:Early tacrolimus concentration is an independent risk factor for post-transplant survival. A tacrolimus concentration >8.28 ng/ml or <6.30 ng/ml is associated with a relatively higher mortality rate.

In this study,we used the Yuan publication Chao Shi Zhu Bing Yuan Hou Lun Zong Lun as the base text,used Zhu Bing Yuan Hou Lun Jiao Zhu edited by Ding Guangdi as the proofreading text,and used"forgetfulness"as the search words.We explored the contents of Zhu Bing Yuan Hou Lun related to the core symptom of dementia-forgetfulness,and analyzed the etiology and mechanism of the disease.After analyzing,Zhu Bing Yuan Hou Lun believes that forgetfulness is mostly caused by emotional changes,internal obstruction of blood stasis,loss of internal organs,deficiency of essence,qi and blood,loss of nourishment of the brain marrow,special diseases such as foot fungus disease,blindly taking cold food,leprosy that has not been treated for a long time,and cumulative disease,etc.This indicates that after more than a thousand years of development,the academic thinking of Zhu Bing Yuan Hou Lun is still of certain guiding significance for the prevention and treatment of dementia in today's clinic,and it further enriches and improves the theoretical understanding of Chinese medicine on dementia,and provides a solid theoretical foundation and new ideas for the prevention and treatment of dementia.

Objective:To investigate the predictive value of preoperative γ-glutamyl transferase/lymphocyte count ratio (GLR) levels for postoperative tumor recurrence in liver transplant recipients with liver cancer.Methods:The clinical data of 158 recipients who were diagnosed with hepatocellular carcinoma (hereinafter referred to as liver cancer) and received liver transplantation at the No. 900 Hospital of the Joint Logistics Support Force of the Chinese People's Liberation Army from January 2008 to October 2022 were retrospectively analyzed. X-tile software, the Kaplan-Meier method, univariate and multivariate Cox regression, and other statistical methods were performed. The predictive value of preoperative GLR levels for postoperative tumor recurrence in liver transplant recipients with liver cancer and the risk factors for tumor recurrence in liver cancer patients post-liver transplantation were analyzed.Results:The X-tile software analysis confirmed that 96.8 was the optimal cutoff value for the preoperative GLR level to predict recurrence. The grouping threshold for survival analysis using the GLR cutoff value was 96.8. The tumor recurrence rates at 1, 3, and 5 years after surgery in the low-level GLR group (90 cases) and the high-level GLR group were 19.3% vs. 44.2%, 31.8% vs. 60.0%, and 34.1% vs. 62.9% (68 cases), respectively, and the differences were statistically significant between the two groups ( P<0.05). The Kaplan-Meier survival curve analysis results showed that the overall postoperative survival rate and recurrence-free survival rate were significantly lower in the high-level GLR group than the low-level GLR group ( P<0.05). The univariate Cox analysis result showed that there were statistically significant differences in preoperative aspartate aminotransferase, alpha fetoprotein, surgery time, maximum diameter of a solitary tumor, presence or absence of microvascular invasion, presence or absence of portal vein tumor thrombus, and preoperative GLR levels between the two groups ( P<0.05). Multivariate Cox analysis results showed that preoperative alpha-fetoprotein ≥400 ng/ml, GLR≥96.8, and the maximum diameter of a solitary tumor ≥5.0 cm were independent risk factors for postoperative tumor recurrence in liver transplant recipients with liver cancer ( P<0.05). Conclusion:GLR levels have a certain predictive value for postoperative tumor recurrence in liver transplant recipients with liver cancer. Furthermore, the postoperative tumor recurrence rate is relatively high when the preoperative GLR level in liver transplant recipients with liver cancer is ≥96.8.

A 24-year-old male patient was admitted to the Organ Transplant Department of the 900th Hospital of the Joint Logistic Support Force on March 13, 2000, due to repeated abdominal distension accompanied by edema of both lower limbs for more than 7 months and aggravated for 1 month. Clinical diagnosis: hepatolenticular degeneration, metabolic encephalopathy, decompensated stage of cirrhosis. Orthotopic liver transplantation was performed under general anesthesia on March 24, 2000. The postoperative recovery is smooth, and the patient has survived for more than 23 years, with normal life and work.

Objective:To investigate and analyze the clinical efficacy of salvage liver transplantation (SLT), rehepatectomy (RH), local ablation (LA), and prognostic risk factors in patients with postoperative recurrence of hepatocellular carcinoma.Methods:Clinical data of 145 patients with recurrent liver cancer in the 900th Hospital of the Joint Logistics Support Force of the People's Liberation Army from January 2005 to June 2018 were retrospectively collected. SLT group, RH group, and LA group included 25, 44, and 76 cases, respectively. Follow-up and statistics were recorded on the overall survival rate, relapse-free survival rate, and complications of the three groups of patients at 1, 2, and 3 years after surgery. Univariate and multivariate COX analyses were used to analyze the prognostic risk factors in patients with recurrent HCC.Results:The overall survival rates of 1, 2, and 3 years following surgery in the SLT, RH, and LA groups were 100.0%, 84.0%, 72.0%, 95.5%, 77.3%, 65.9%, 90.8%, 76.3%, and 63.2%, respectively, when the recurrence of liver cancer met the Milan criteria. The overall survival rate did not differ statistically between SLT and RH ( P = 0.303) or between RH and LA ( P = 0.152). There were statistically significant differences in recurrence-free survival between SLT and RH or RH and LA ( P = 0.046). There was no statistically significant difference in the incidence of complications between SLT and RH or RH and LA ( P > 0.017). Age > 65 years was an independent risk factor affecting the overall survival rate in patients with recurrent HCC. Age > 65 years and recurrence time < 24 months were independent risk factors affecting the recurrence-free survival rate in patients with recurrent HCC. Conclusion:SLT is the best treatment option when the recurrence of HCC meets Milan's criteria. RH and LA are the appropriate treatment plans for recurrent HCC when the liver source is limited.

Objective:To explore the clinical efficacy of liver transplantation for Wilson's disease(WD).Methods:From January 1999 to November 2021, clinical data were retrospectively reviewed for 16 recipients with WD undergoing liver transplantation.There were 9 males and 7 females with an age range of 29.5(14~54)years.They were followed up by telephone, outpatient services and hospitalization.The starting point of follow-up was operation date.And recipient death was an endpoint.Postoperative survival, improvement of neuropsychiatric symptom, changes of corneal K-F ring, altered levels of liver function and serum copper-protein at Month 1 post-operation were observed.The follow-up deadline was November 24, 2021.Results:15 recipients underwent classical orthotopic liver transplantation and the other one recipient underwent living-related liver transplantation.No perioperative deaths occurred.All 16 recipients were followed up for 122(6~260)months.The 1-, 5-, and 10-year survival rates were 93.8%、85.2%and 75.8%, respectively.Among 10 recipients with corneal K-F ring positive with varying degrees after operation and was disappeared in 2 recipients at 7 and 11 months.Among 5 recipients with neuropsychiatric manifestation, 4 recipients showed ameliorative neuropsychic symptoms with varying degrees after operation and 1 recipient died.All the levels of liver function and serum copper-protien of all recipients recovered obviously in 1 month and the 1-, 5-, and 10-year post-operation.Conclusions:Classical orthotopic liver transplantation and living-related liver transplantation not only effectively improves copper metabolism of patient with WD and relieves their severe neurological manifestation, but also improves their life and prolongs survival, which is worthy of clinical promotion.

Vaccines have made great contributions to the prevention of infectious diseases, but vaccine hesitancy is widespread in the world. The reasons for vaccine hesitancy are complex, but the main reasons are the lack of public awareness of vaccine-preventable diseases and the lack of confidence in vaccine effectiveness and safety. In the context of the continuous spread of the coronavirus disease 2019 (COVID-19) epidemic, boosting public confidence and ensuring the orderly development of the vaccination work of COVID-19 vaccines and conventional vaccines are necessary to curb the resurgence of the COVID-19 epidemic and prevent the outbreak of various infectious diseases in China. Under the current situation, the main measures to deal with vaccine hesitancy are to play the role of health care institutions, improve public health literacy, normalize the public opinion orientation of the media platform, strengthen the supervision of vaccine clinical research and production, and do a good job in surveillance and compensation for adverse events following immunization.
