Objective To study the causes, diagnosis and treatment of the spontaneous perforation of sigmoid colon(SPSC). Methods The clinical data of 11 patients with SPSC admitted into our hospital from January. 1984 to September. 2000 were analyzed retrospectively. Results All the 11 cases of SPSC were proved by operation. Among them, 4 cases had chronic constipation history, 1 case complicated with mild proctoptoma before operation and the other 6 cases had no special records. 9 cases were misdiagnosed as perforation of acute appendicitis, perforation of upper gastroenteric tract, perforation of colon carcinoma, inflammatory perforation or fecal mass perforation. 2 cases recovered after repairing operation; of 9 cases underwent colostomy and other procedure, 7 cases recovered and colostomy closure was done 2-3 months after operation. 2 cases died after operation. Conclusions The occurrence of SPSC is closely related to the configuration and position of the patient's sigmoid colon. Increase of intra-abdominal pressure and intra-intestinal pressure are the predisposing causes of the disease. This disease has no special clinical manifestation. The key to diagnosis is a full knwledge of the disease before operation. The main treatment is operation. The mode of operation is determined according to patient's age, general condition, severity of abdominal pollution, attacking time. The best mode of operation is to repair and close the perforation or to resect and anastomose the bowel and colostomy.

Tumor recurrence is the main issue that affects the long-term survival of recipients after liver transplantation for hepatocellular carcinoma. Accurate preoperative evaluation and proper selection of transplant recipients are the key factors affecting the long-term prognosis of recipients undergoing liver transplantation for hepatocellular carcinoma. Neutrophil, lymphocyte, C-reactive protein, platelet and fibrinogen (FIB) are major biomarkers that indicate inflammatory response of the host. Multiple studies have found that these biomarkers may not only represent the inflammatory response, but also could be integrated to predict tumor recurrence and long-term survival rate of the recipients following liver transplantation for hepatocellular carcinoma. These biomarkers mainly consist of neutrophil-to-lymphocyte ratio (NLR), Glasgow prognostic score (GPS), FIB, platelet-to-lymphocyte ratio (PLR) and prognostic nutritional index (PNI), etc. In this article, research progresses on predictive effect of inflammatory biomarkers on prognosis of liver transplantation for hepatocellular carcinoma were reviewed.

Objective:To explore the prognostic values of neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio(PLR)and NLR-PLR score for carcinoma(HCC)patients undergoing liver transplantation(LT).Methods:From July 2015 to October 2021, clinical data are retrospectively reviewed for 110 HCC patients undergoing orthotopic LT at Third Hospital of Hebei Medical University.The values of NLR and PLR were calculated.And the cut-off values of NLR and PLR were obtained by receiver operating characteristic (ROC) curve and then grouped according to the cut-off values.Survival time is analyzed by Kaplan-Meier method and Log-rank test performed for inter-group comparison.Univariate and multivariate analyses are performed based on Cox proportional risk regression model.NLR <3.37 and PLR <105.96 are denoted as 0 point while NLR ≥3.37 and PLR ≥105.96 as 1 point.Two points are added up as NLR-PLR score.According to NLR-PLR score, they are divided into 3 groups of 0, 1 and 2.Results:Median overall survival(OS)is 27 months in patients with NLR-PLR score 0, 26.5 months in patients with NLR-PLR score 1 and 6 months in patients with NLR-PLR score 2.Median OS in patients with NLR-PLR score 2 is significantly shorter than that in those with NLR-PLR score 0/1.And the difference is statistically significant( P<0.001).Median disease-free survival(DFS)is 24.5 months in NLR-PLR 0 group, 24 months in NLR-PLR 1 group and 6 months in NLR-PLR 2 group.The difference is statistically significant( P=0.002).Univariate analysis show that Child-Pugh grade, MELD score, NLR/PLR level, NLR-PLR score, complying with University of California San Francisco Criteria(UCSF)criteria and absence/presence of microvascular invasion(MVI)have an impact on patient survival.Further multivariate analysis show that NLR-PLR score, complying with UCSF criteria and MELD score are independent risk factors affecting patients' prognosis and survival. Conclusions:NLR, PLR and NLR-PLR score may predict long-term survival of patients.And NLR-PLR score is an independent risk factor for patient survival.It has more predictive value than NLR/PLR.

Hepatitis C virus infection is a global public health issue， and the emergence of direct-acting antiviral agents has brought revolutionary breakthroughs in the treatment of hepatitis C patients. Although direct-acting antiviral agents have a marked therapeutic effect in adult patients， there are still many challenges in the treatment of special populations such as pregnant women， infants， young children， and adolescents. This article reviews the current status of antiviral therapy for these special populations with hepatitis C and the problems that need to be solved， in order to provide reference and guidance for clinical workers.
