Methods A cohort of 377 middle aged HBV infected men in Qidong was followed from 1989 for 13. 25 years. HCC cases were registered. A matched case-controlled study was conducted on 32 pairs of inherent HCC cases with non-HCC controls. Serum HBeAg was measured by ELISA. cccDNA was detected by semi-nested PCR and verified by DNA sequencing. Standard statistical comparison between the prevalence of each HBV marker in HCC versus control group provided the odds ratio and P-value was used to evaluate its association strength with HCC occurrence. Results Serum HBeAg prevalence was 53. 1% (17/32) in HCC group versus 15. 6% (5/32) in controls, odds ratio (OR) =6. 12, P

ObjectiveTo explore the effect of sodium selenite on gentamicin-induced ototoxicity.MethodsTwenty guinea pigs were randomly divided into the experimental group and control group with 10 animals in each group. The animals were treated with i.m injection of gentamicin (200 mg/kg/d for 8 consecutive days, and at same time, the experimental group was added with p.o tablet of sodium selenite (1 mg/kg/d). Before and after the administration, hearing function was evaluated by examination for auditory brain stem responses (ABR). The cochlear outer haircells were observed by scanning electronic microscope (SEM) and transmission electronic microscope (TEM).ResultsABR threshold of the control group was about 30 dB above that of the experimental group (P<0.01). The latency of waveⅠof the control group was about 0.23 ms above that of the experimental group (P<0.01). Under SEM, the cilia of the majority outer hair cells of the control group lodged even disappeared, while that of the experimental remained regular. Under TEM, in outer hair cells of the control group, mitochondrial crests were obscure, out-membrane was damaged and local protruding, the number of secondary lysosomes was increased, myeloid bodies appeared, but in the experimental group, outer hair cells basically remained normal.ConclusionSodium selenite has antitoxic effect on guinea pig cochlea injury induced by gentamicin in vivo.

OBJECTIVE: To explore the clinical and genetic characteristics of a patient with 17-hydroxylase/17,20-lyase deficiency. METHODS: The patient was infertile without contraception. Laboratory examination showed her chromosomal karyotype to be 46, XX. DNA sequencing was performed to detect variants of CYP17A1 gene in the patient and her family members. RESULTS: Sanger sequencing revealed that the patient has carried homozygous variant c.1486C>T in the exon 8 of the CYP17A1 gene, which resulted in substitution of arginine by cysteine (p.Arg496Cys). Her family members were all heterozygotes for the same variant. CONCLUSION Homozygous variant of the CYP17A1 gene c.1486C>T probably underlay the 17-hydroxylase deficiency in this patient. Above finding has enabled accurate genetic counseling and prenatal diagnosis for her family.

The aging disease associated with type 2 diabetes mellitus(T2DM)is a hot research topic in the field of diabetes at present.Sarcopenia has become the third major complication of T2DM after microvascular and macrovascular diseases,which could lead to the occurrence and development of various adverse events such as fracture,disability,and dysfunction.The spleen belongs to the earth,is in the middle jiao,governs transportation and transformation,and governs muscle.The functional activities of the spleen manifesting in normal transformation and transportation,the distribution of cereal essence,and the nourishment of muscles are necessary for normal physiological functions to be exerted.Recent studies have shown that skeletal muscle cell ferroptosis plays an important role in the pathogenesis of T2DM sarcopenia.Based on the theory of"spleen governing transportation and transportation and governing muscle",this study explores the pathogenesis of T2DM sarcopenia from the perspectives of the pathogenesis of"dysfunction of spleen in transportation,deficiency of cereal essence,obstruction of dampness and turbidity,and muscle dystrophy"in traditional Chinese medicine and the pathological mechanism of"skeletal muscle cell ferroptosis"in modern medicine.It summarizes the principles of traditional Chinese medicine prevention and treatment for T2DM sarcopenia based on the spleen,to provide theoretical support for enriching the theoretical connotation of spleen visceral state,as well as basic research and clinical trials on the prevention and treatment of T2DM sarcopenia with traditional Chinese medicine.

Objective:To explore the role of ductular reaction in assessing the efficacy of liver transplantation.Method:From January 2015 to December 2020, he relevant clinical data were retrospectively reviewed for 100 recipients and their corresponding donors at Shulan (Hangzhou) Hospital. They were assigned into two groups of hepatic steatosis (HS group, 65 cases) and non-hepatic steatosis (non-HS group, 35 cases) according to whether or not receiving steatosis donated liver. Furthermore, based upon the occurrence of early allograft dysfunction (EAD), the participants were categorized into two groups of EAD (33 cases) and non-EAD (67 cases). The degree of bile duct reaction ductular reaction was defined by the percentage of staining area occupied by cytokeratin 19 (CK19) -positive bile duct cells in immunohistochemical-stained specimens. Donor of ductular reaction were compared between HS/non-HS and EAD/non-EAD groups. The risk factors for EAD were identified by univariate and multivariate Logistic regression analysis. Subgroup analysis was conducted based upon the level of ductular reaction (DR number) in donors (DR=0.4 as a threshold) and whether or not donors exhibited steatosis. The impact of DR was examined on the incidence of EAD and survival post-liver transplantation in steatosis donors.Result:The level of DR was higher in steatosis donor than that in non-steatosis donor [ (0.59%±0.385%) vs. (0.32%±0.194%), P<0.01]. And it was higher in EAD group than that in non-EAD group [ (0.72%±0.449%) vs. (0.38%±0.226%), P<0.01]. Multivariate logistic regression analysis showed that a high level of ductular reaction was an independent risk factor for EAD post-liver transplantation in donor. Subgroup analysis revealed that receiving a steatosis donor with low ductular reaction (DR<0.4%) had comparable levels of EAD occurrence and overall survival rate to receiving a non-steatosis donor. Conclusion:Steatosis with low ductular reaction donor may be safely applied for liver transplantation. And assessing donor injury based upon ductular reaction can effectively expand the clinical application of steatosis donors.
