Objective To investigate the application value of tenofovir alafenamide fumarate (TAF) in elderly patients with chronic hepatitis B (CHB) and its influence on bones and kidneys. Methods A total of 36 CHB patients, aged ≥60 years, who received TAF antiviral therapy in Qingdao Municipal Hospital, The Affiliated Hospital of Qingdao University, Qingdao Sixth People's Hospital, Chengyang People's Hospital, and Jimo People's Hospital from June 2021 to October 2022 were enrolled in this study, and all patients received TAF (25 mg/d) antiviral therapy. Related data were collected at baseline and weeks 24 and 48 of treatment, including virological indicators, biochemical parameters, urinary protein electrophoresis indices, transient elastography (FibroScan), and bone mineral density. Virological indicators included high-sensitivity HBV DNA quantification; biochemical parameters included total bilirubin, direct bilirubin (DBil), indirect bilirubin (IBil), alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, gamma-glutamyl transpeptidase, total bile acid (TBA), glucose, blood urea nitrogen, creatinine, estimated glomerular filtration rate, and cystatin C (Cys C); urinary protein electrophoresis indices included urinary β2 microglobulin (β2-MG), urinary retinol (URBP), and urinary α1 microspherin (α1-MG). The paired t -test was used for comparison of normally distributed continuous data before and after treatment, and the Wilcoxon signed-rank test was used for comparison of non-normally distributed continuous data before and after treatment; the chi-square test or the Fisher's exact test was used for comparison of categorical data. Results A total of 36 CHB patients completed 24 weeks of follow-up. The complete virological response rate after 24 weeks of treatment was higher than that at baseline [83.3% (30/36) vs 77.8% (28/36), χ 2 =0.36, P =0.55], and there were significant reductions in DBil ( t =-2.42, P =0.02) and Cys C ( t =-4.34, P < 0.001) from baseline to week 24. A total of 18 CHB patients completed 48 weeks of follow-up. The complete virological response rate after 48 weeks of treatment was higher than that at baseline (94.4% vs 77.8%, χ 2 =2.22, P =0.34), and there were significant increases in IBil ( t =2.43, P =0.03), TBA ( Z =-2.24, P =0.03), and bone mineral density T score of lumbar vertebra ( t =2.92, P = 0.01) and femoral neck ( t =2.42, P =0.03) and a significant reduction in liver stiffness measurement ( t =-2.31, P =0.03). There were no significant changes in β2-MG, URBP, and α1-MG after treatment (all P > 0.05). Conclusion TAF has a good antiviral effect in CHB patients aged ≥60 years and can help more CHB patients achieve complete virological response, without causing damage to the kidney, and it can also improve bone mineral density and liver fibrosis degree.

Hepatocellular carcinoma (HCC) has an insidious onset, and most patients are in the advanced stage when attending the hospital and thus lose the opportunity for radical surgical resection, which results in the poor prognosis of patients. With the development of clinical treatment, the treatment of advanced HCC has gradually transitioned from the relatively single and limited treatment options in the past to the new model of comprehensive treatment. In recent years, immunotherapy, represented by immune checkpoint inhibitors (ICIs), has become widely used in clinical practice. At present, a number of clinical studies have been conducted for immunotherapy combined with local and targeted antitumor therapy, and in particular, ICIs combined with targeted therapy have become a research hotspot in the field of HCC treatment. This article reviews the research advances in immunotherapy for the treatment of HCC.

Objective:To investigate how gender differences between the donor and the recipient affect the effectiveness of antithymocyte globulin (ATG) and pure peripheral blood stem cell (PBSC) hematopoietic stem cell transplantation (haplo-HSCT) in the treatment of malignant hematological diseases.Methods:From February 2015 to September 2020, 648 hematological malignancies patients underwent myeloablative condition regimen haplo-HSCT treatment at the Bone Marrow Transplant Center of the First Affiliated Hospital of Zhejiang University. The median age was 32 (14-62) years, with 363 males (56.0% ) and 285 females (44.0% ) present. 242 cases of acute lymphoblastic leukemia (ALL) (37.3% ) , 293 cases of acute myeloid leukemia (AML) (45.2% ) , 56 cases of myelodysplastic syndrome (MDS) (8.7% ) , 27 cases of non-Hodgkin's lymphoma (NHL) (4.2% ) , and 30 cases of other hematological malignancies (4.6% ) .Results:① The 3-year overall survival (OS) , DFS, the incidence of Ⅱ-Ⅳ grade acute graft-versus-host disease (aGVHD) , the incidence of Ⅲ-Ⅳ grade aGVHD, the 3-year incidence of moderate & severe chronic GVHD (cGVHD) , severe cGVHD, the 3-year incidence of relapse, and NRM of the whole group were (73.10±1.90) % , (70.80±1.90) % , (33.96±1.87) % , (13.08±1.33) % , (35.10±2.14) % , (10.66±1.38) % , (19.43±1.67) % , and (9.80±1.24) % , respectively. ②There was no statistically significant difference between the donor-recipient gender match and donor-recipient gender mismatch groups in the 28-day cumulative neutrophil engraftment rate, 28-day cumulative platelet engraftment rate, the incidence of Ⅱ-Ⅳ grade aGVHD, the incidence of Ⅲ-Ⅳ grade aGVHD, 3-year OS, 3-year DFS, the cumulative incidence of relapse, NRM, and incidence of moderate & severe cGVHD, severe cGVHD. ③The 28-day cumulative neutrophil engraftment rate did not differ statistically between the male-female, female-female, male-male, and female-male groups ( P=0.148) . The incidence of Ⅱ-Ⅳ grade aGVHD, the incidence of Ⅲ-Ⅳ grade aGVHD, 3-year OS, 3-year DFS, cumulative relapse rate, and NRM, and the incidence of cGVHD were not statistically different among the four groups ( P>0.05) . The 28-day cumulative platelet engraftment rate of the female-male group was significantly lower than male-female group, and the female-female group [ (91.45±2.63) % vs. (94.77±1.75) % , P=0.004; (91.45±2.63) % vs. (95.54±2.05) % , P=0.005]. No significant difference existed in the 28-day cumulative platelet engraftment rate between the female-male group and the male-male group [ (91.45±2.63) % vs. (95.08±1.41) % , P=0.284]. ④Among patients ≤35 years old, the 3-year incidence of severe cGVHD patients receiving sister donors and sibling donors were (26.71±5.90) % and (10.33±4.43) % , respectively ( P=0.054) . Patients accepting daughter donors and son donors had a 3-year incidence of moderate and severe cGVHD that was 40.07% vs. 27.41% , respectively, among those over 35 (40.07±6.65) % vs. (27.41±4.54) % ( P=0.084) . ⑤Female donors to male recipients had a significantly lower 28-day cumulative platelet engraftment rate compared to the other groups [ (91.45±2.63) % vs. (95.08±0.95) % , P=0.037]. ⑥ Female donors to male recipients had a significantly lower 28-day cumulative platelet engraftment rate than the other groups in the ATG-Fresenius (ATG-F) 10 mg/kg group [ (89.29±4.29) % vs. (94.49±1.45) % , P=0.037]. But when compared to the other groups in the Rabbit Antihuman Thymocyte Immunoglobulin (rATG-T) 6 mg/kg group, the 28-day cumulative platelet implantation rate between female donors and male recipients was not significantly different [ (93.44±3.38) % vs. (95.62±1.26) % , P=0.404]. Conclusion:The main clinical outcomes of patients with malignant blood diseases following transplantation are unaffected by the gender combination of the donor and patient in the haplo-HSCT mode based on ATG and PBSC sources. Female donors to male recipients have a lower 28-day cumulative platelet engraftment rate and longer platelet engraftment times.

Objective:To analyze the effect of role standardized progressive nursing model on delivery fear and delivery outcome of primiparas.Methods:Using the convenient sampling method, a total of 200 primiparas who were admitted to Ruian Maternal and Child Health Hospital of Zhejiang Province from January to December 2020 were selected as the research objects. According to the random number table method, they were divided into the control group and the observation group, with 100 cases in each group. Patients in the control group were given routine nursing intervention, while patients in the observation group were given role standardization progressive nursing mode on the basis of the control group. Childbirth Attitude Questionnaire (CAQ) and Childbirth Self-Efficacy Inventory-32 (CBSEI-32) were used to investigate, and the outcomes of delivery in the two groups were counted.Results:Before intervention, there was no statistically significant difference in CAQ and CBSEI-32 scores between two groups ( P>0.05) . After intervention, the scores and total scores of all dimensions of CAQ in the observation group were lower than those in the control group, and the outcome expectation, delivery self-efficacy expectation score in CBSEI-32 were higher than those in the control group, and the differences were all statistically significant ( P<0.05) . There was no statistically significant difference in the incidence of postpartum hemorrhage, lateral perineal resection and premature rupture of membranes in the observation group ( P>0.05) . The cesarean section rate in the observation group was lower than that in the control group, and the difference was statistically significant ( P<0.05) . Conclusions:The role standardized progressive nursing model can alleviate the fear of delivery, improve the sense of self-efficacy during delivery and improve the outcome of delivery, which is worthy of clinical application.

Objective:To study the expression of programmed death ligand-1 (PD-L1) in tumor cells and CD8 +T lymphocytes in tumor infiltrating lymphocytes, and to analyze the correlation of PD-L1 expression with infiltration of CD8 +T lymphocytes and clinicopathologic features in salivary gland lymphoepithelial carcinoma (LEC). Methods:Forty-two cases of primary salivary LECs and 21 cases of secondary salivary LECs were enrolled at the Department of Oral Pathology, Shanghai Ninth People′s Hospital, Shanghai Jiaotong University between 2015 and 2017. The expression of Epstein-Barr (EB) virus, PD-L1 and CD8 was examined using chromogenic in situ hybridization (CISH) and immunohistochemistry (IHC) staining. The data were analyzed using SPSS 23.0 software package.Results:EB virus was detected in 61 cases (61/63, 96.8%), including 42 (42/42, 100%) primary LECs and 19 (19/21, 90.5%) secondary LECs. The PD-L1 positive rate (score ≥1) was 97.6% (41/42), and its high-expression rate (score ≥20) was 78.6% (33/42) in primary LECs. The PD-L1 positive rate (score ≥1) was 71.4% (15/21), and its high-expression rate (≥20) was 38.1% (8/21) in secondary LECs. However, the PD-L1 positive rate (score ≥1, P=0.004) and high-expression rate (score ≥20, P=0.001) in primary LECs were higher than those in secondary LECs. There was no difference in the infiltration degree of CD8 +T lymphocytes between primary and secondary LECs. There was a significant correlation between the expression of PD-L1 and CD8 in primary LECs ( P=0.001) and in secondary LECs ( P=0.048), respectively. Conclusions:There is PD-L1 expression in primary and secondary salivary LECs, while the expression rate is higher in primary LECs than secondary LECs. The combination of PD-L1 expression and CD8 +T lymphocytes′ presence suggest that most LEC patients might be responsive to immunotherapy, and primary LECs might be more significantly responsive than secondary LECs.

Age, history of hypertension, white blood cell count, D-dimer, and fibrinogen were the risk factors for death of COVID-19 (odds ratio ( OR)=1.170, 10.405, 3.055, 1.128 and 1.343, respectively, all P<0.05). Conclusion:Age, underlying hypertension, white blood cell count, D-dimer and fibrinogen are independent prognostic factors for COVID-19.

Objective: To explore the association of TBX5 polymorphisms and environmental exposure index with susceptibility to oral cancer. Methods: A case-control study was conducted to collect 300 oral cancer patients hospitalized in the Department of Oral and Maxillofacial Surgery, the First Affiliated Hospital of Fujian Medical University from September 2010 to December 2016. A total of 445 non-tumor patients were selected as the control group. Questionnaires were used to collect the information of all subjects and 5 ml peripheral blood was collected to detect single nucleotide polymorphisms (SNPs) of the rs10492336 locus of TBX5 gene. According to the environmental exposure index score, subjects were divided into two groups, low risk group (0-2.31) and high risk group (2.32-11.76). To analyze the association of TBX5 gene rs10492336 SNPs, environmental exposure index and oral cancer and its interactions. Results: The age of all subjects in the case group and control group were (56.19±13.10) years and (54.56±12.48) years old. Compared with CC genotype, the OR (95%CI) values of the co-dominant genetic model AC genotype and the dominant genetic model AC+AA genotype were 0.69 (0.49-0.98) and 0.70 (0.51-0.97), respectively. Compared with the low risk group, the OR (95%CI) risk of oral cancer in the high risk group was 3.72 (2.55-5.43). The results of gene-environment interaction analysis showed that compared with the group with CC genotype and high risk of environmental exposure index, the OR (95%CI) value of oral cancer in the group with AC+AA genotype and low risk of environmental exposure index was 0.18(0.10-0.31). Furthermore there was a multiplicative interaction between rs10492336 SNPs and environmental exposure index (β=-0.405, P<0.001). Conclusion This study suggests that the TBX5 gene rs10492336 SNPs and environmental exposure index were associated with oral cancer. And there was a multiplication interaction between rs10492336 SNPs and environmental exposure index.
