Objective To investigate the relationship between the levels of serum suppressor of cytokine signaling 3(SOCS3),growth differentiation factor-15(GDF-15)and liver fibrosis in patients with type 2 dia-betes mellitus(T2DM)combined with non-alcoholic fatty liver disease(NAFLD).Methods A total of 320 patients with T2DM combined with NAFLD who were hospitalized in this hospital from May 2023 to May 2024 were selected as the study group,and another 320 patients with simple T2DM admitted during the same period were selected as the control group.The levels of serum SOCS3 and GDF-15 were determined by en-zyme-linked immunosorbent assay(ELISA).Pearson correlation analysis was used to analyze the correlation between SOCS3,GDF-15 levels and liver fibrosis indicators.Logistic regression analysis was used to analyze the factors affecting the degree of liver fibrosis.The receiver operating characteristic(ROC)curve was used to analyze the diagnostic value of serum SOCS3 and GDF-15 for the degree of liver fibrosis in patients.Results Compared with the control group,the levels of serum SOCS3,GDF-15,5,type Ⅲ procollagen peptide,laminin and type Ⅳ col-lagen in the study group were significantly increased(P＜0.05).There were statistically significant differ-ences in the levels of type Ⅲ procollagen peptide,laminin and type Ⅳ collagen between the mild to moderate group and the severe group(P＜0.05).Compared with the mild to moderate group,the levels of serum SOCS3 and GDF-15 in the severe group were significantly increased(P＜0.05).The results of Pearson corre-lation analysis showed that serum SOCS3 and GDF-15 in patients with T2DM combined with NAFLD were positively correlated with type Ⅲ procollagen peptide,laminin,and type Ⅳ collagen(P＜0.05).Serum SOCS3,GDF-1 5,type Ⅲ procollagen peptide,laminin and type Ⅳ collagen are risk factors affecting the degree of liver fibrosis in patients with T2DM combined with NAFLD(P＜0.05).The results of the ROC curve showed that the combined diagnosis of serum SOCS3 and GDF-15 for the degree of liver fibrosis in patients with T2DM complicated with NAFLD had the highest area under the curve(AUC),which was superior to the individual diagnosis of each(both P＜0.05),with a corresponding sensitivity of 69.08％and a specificity of 85.71％.The combined diagnosis of the degree of liver fibrosis in patients with T2DM complicated with NAFLD by serum SOCS3,GDF-15,type Ⅲ procollagen peptide,laminin,and type Ⅳ collagen had the highest AUC,which was superior to the individual diagnosis of each index(all P＜0.001),with a corresponding sensi-tivity of 89.47％and a specificity of 97.02％.Conclusion The levels of serum SOCS3 and GDF-15 are elevated in patients with T2DM combined with NAFLD,.The combined diagnosis of serum SOCS3,GDF-15,type Ⅲ procolla-gen peptide,laminin,and type Ⅳ collagen has a high value in the degree of liver fibrosis in patients.

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 build a reference fetal growth chart for the Chinese population based on fetal ultrasound measurements.Methods::This was a multicenter, population-based retrospective cohort study. Longitudinal ultrasound measurement data were collected from 24 hospitals in 18 provinces of China from 1 st September through 31 st October of 2019. The estimated fetal weight (EFW) was calculated based on head circumference, abdominal circumference, and femur length using Hadlock formula 3. Fetal growth curves were estimated using a two-level linear regression model with cubic splines. All participants were divided into two groups: the northern group ( n = 5829) and the southern group ( n = 3246) based on the geographical division of China and male fetus group ( n = 4775) and female fetus group ( n = 4300) based on fetal gender. The EFW was compared by fetal gender and geographical group. All statistical models were adjusted for maternal sociodemographic characteristics. Results::A total of 9075 participants with 31,700 ultrasound measurement records were included in this study. Male fetuses demonstrated significantly larger EFW compared to female ones starting at 16 weeks of gestation and extending to delivery (global test P < 0.01). The overall geographic difference in EFW was significant (global test P = 0.03), and week-specific comparisons showed that the northern group had a greater EFW starting at 15 weeks of gestation and extending to 29 weeks of gestation, although this difference did not extend to the time of delivery. The Z-score of EFW confirmed that our Chinese fetal growth charts differed from previously published standards. Conclusion::This study provides EFW and ultrasound biometric reference measurements for Chinese fetuses and reveals differences from other fetal growth charts. The chart is worth promoting in more regions of China but should be tested prudently before use.

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 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.

OBJECTIVES: The waiting room for surgery is an area set up to improve the surgical turnover rate, but the waiting time for surgery is uncertain. Patients are prone to negative emotions that affect their physiological state during waiting time. This study aims to explore the effect of Mandala painting intervention based on Mandala-self theory on the emotion and physiological state of patients waiting before operation. METHODS: The patients in the control group ( RESULTS: Diastolic pressure, heart rate, and happiness and excitement showed no statistical significance in the time effect, intervention effect, and interaction between the 2 factors (all CONCLUSIONS The application of Mandala painting in the operation waiting room is feasible and can effectively regulate the patients' negative mood and systolic pressure, as well as shorten the waiting time of perception.
