Objective: To investigate the intentions of mothers of ageappropriate girls in Qingdao to vaccinate their daughters against human papillomavirus (HPV), so as to provide theoretical guidance for targeted health education in the future. Methods: A multistage random sampling method was adopted to conduct a crosssectional study among 2 244 mothers of girls aged 12-14 years in Qingdao from March to December 2023. The Mann-Whitney U test was used for group comparisons, and Logistic regression was performed to analyze the factors that influenced maternal intention to vaccinate their ageappropriate daughters against HPV. Results: Among the surveyed mothers, 89.22% (n=2 002) intended to vaccinate their daughters against HPV, and 68.58% (n=1 539) had fully vaccinated or had plans to complete it for themselves. The knowledge score of mothers intended to vaccinate their daughters was 10 (8, 11). The multivariate Logistic regression analysis showed that mothers aged >45 years (OR=0.19), those with an annual family income of 60 000-<150 000 yuan (OR=0.65), 150 000-<300 000 yuan (OR=0.58), 300 000-500 000 yuan (OR=0.22), and those with higher knowledge scores (OR=0.90) were more likely to vaccinate their daughters (P<0.05). Mothers with a junior college or undergraduate degree (OR=1.66), those who never or occasionally screened for HPV (OR=1.58), those who were intended to be vaccinated, not planning to complete the fullcourse vaccination, or overaged and unvaccinated (OR=7.13), those who were not concerned about their daughters HPV infection (OR=2.54), and those whose daughters were not in adolescence (OR=1.93) were less intended to vaccinate their daughters (P<0.05). The primary reasons for vaccine hesitancy were vaccine safety concerns (65.06%), followed by the belief of mothers that "the children is to young, and can be vaccinated when they are older" (13.25%). Conclusions Mothers of eligible girls in Qingdao have relatively higher intentions to vaccinate their daughters against HPV, and willingness is influenced by factors such as the mothers vaccination status, knowledge level, and daughters development stage. It is recommended to strengthen targeted health education, improve the cognitive level and acceptance of mother, and increase the vaccination rate of HPV vaccines.

Objective:To discuss the effect of zanubrutinib(BGB-3111)combined with bortezomib(Btz)on the apoptosis of the human multiple myeloma(MM)cells,and to clarify its possible mechanism.Methods:The human MM cell lines U266,PS-R,RPMI8226,KMS28-PE,KMS28-BM,and H929 were cultured in vitro.Western blotting method was used to detect the expression level of Bruton's tyrosine kinase(BTK)protein in various cells;cell counting kit-8(CCK-8)method was used to detect the survival rates of the RPMI8226,U266,and KMS28-BM cells after treated with 0,10,20,30,40,and 50 μmol·L?1 BGB-3111.The RPMI8226,U266,and KMS28-BM cells at the logarithmic growth phase were selected and divided into control group,BGB-3111 group,Btz group,and BGB-3111+Btz group.Flow cytometry was used to detect the apoptotic rates of the cells in various groups;Western blotting method was used to detect the expression levels of myeloid cell leukemia 1(MCL-1),B-cell lymphoma-2(Bcl-2),Bcl-2-interacting mediator of cell death(Bim),phosphorylated Bim(p-Bim),P65,phosphorylated P65(p-P65),tumor necrosis factor receptor-associated factor(TRAF)2,and tumor necrosis factor alpha-induced protein 3(A20)in different kinds of cells.The U266 cells were divided into A20 overexpression group(A20-OE group)and empty vector control group(EV group).Each group was further divided into control group,BGB-3111 group,Btz group,and BGB-3111+Btz group.The corresponding plasmids were transfected;Western blotting method was used to detect the transfection efficiency of the cells in various groups;flow cytometry was used to detect the apoptotic rates of the cells in various groups after over-expression of A20.Results:The Western blotting results showed that compared with KMS28-BM cells,the expression levels of BTK protein in the U266,RPMI8226,and H929 cells were significantly increased(P<0.05 or P<0.01).The CCK-8 results showed that compared with 0 μmol·L?1 BGB-3111 group,the survival rates of the RPMI8226 and U266 cells in 10,20,30,40,and 50 μmol·L?1 BGB-3111 groups were significantly decreased(P<0.05 or P<0.01),and the survival rates of the KMS28-BM cells in 20,30,40,and 50 μmol·L?1 BGB-3111 groups were significantly decreased(P<0.05).Compared with RPMI8226 and U266 cells,the survival rates of the KMS28-BM cells in 20,30,and 40 μmol·L?1 BGB-3111 groups were significantly increased(P<0.05).Therefore,10 μmol·L?1 BGB-3111 was selected for subsequent experiments.The flow cytometry results showed that compared with control group,the apoptotic rates of the RPMI8226 and U266 cells in BGB-3111 group,Btz group,and BGB-3111+Btz group were significantly increased(P<0.05 or P<0.01);compared with BGB-3111 group and Btz group,the apoptotic rates of the RPMI8226 and U266 cells in BGB-3111+Btz group were significantly increased(P<0.01);compared with control group,the apoptotic rates of the KMS28-BM cells in Btz group and BGB-3111+Btz group were significantly increased(P<0.01);compared with BGB-3111 group,the apoptotic rate of the KMS28-BM cells in BGB-3111+Btz group was significantly increased(P<0.01);compared with EV group,the apoptotic rates of the cells in A20-OE group in Btz group and BGB-3111+Btz group were significantly increased(P<0.05).The Western blotting results showed that compared with control group,the expression levels of Bim protein in the RPMI8226 and U266 cells in BGB-3111 group,Btz group,and BGB-3111+Btz group were significantly increased(P<0.05),while the expression levels of MCL-1,p-Bim,and Bcl-2 proteins in the RPMI8226 and U266 cells in Btz group and BGB-3111+Btz group were significantly decreased(P<0.05);compared with BGB-3111 group and Btz group,the expression levels of Bim protein in the RPMI8226 and U266 cells in BGB-3111+Btz group were significantly increased(P<0.05),while the expression levels of MCL-1,p-Bim,and Bcl-2 proteins were significantly decreased(P<0.05).Compared with control group,the expression levels of p-P65 protein in the RPMI8226 and U266 cells in Btz group and BGB-3111+Btz group were significantly increased(P<0.05),while the expression levels of TRAF2 and A20 proteins were significantly decreased(P<0.05);compared with BGB-3111 group and Btz group,the expression levels of p-P65 protein in the RPMI8226 and U266 cells in BGB-3111+Btz group were significantly increased(P<0.05),while the expression levels of TRAF2 and A20 proteins were significantly decreased(P<0.05).The flow cytometry results showed that compared with EV group,the expression level of A20 protein in A20-OE group cells was significantly increased(P<0.01).Conclusion:BGB-3111 induces apoptosis in the MM cells by inhibiting BTK activity and enhances the pro-apoptotic effect of Btz.Over-expression of A20 increases the sensitivity of the MM cells to the combined treatment.The antitumor effect may be related to the inhibition of the nuclear factor kappa B(NF-κB)signaling pathway.

Kawasaki disease（KD）is an acute systemic vasculitis primarily affecting small- and medium-sized arteries in children，with widespread inflammation as the major pathological hallmark. A subset of patients with KD exhibit resistance to high-dose intravenous immunoglobulin（IVIG）therapy，which significantly increases the risk of developing severe cardiovascular complications，particularly coronary artery lesions（CAL）. Interferon gamma-inducible protein 10（IP-10），a chemokine，exerts its biological functions by binding to its specific receptor，chemokine receptor 3（CXCR3）. In the relevant research on KD，the association between IP-10 and IP-10 gene polymorphism with KD has garnered significant attention from both domestic and international researchers. This article reviews the recent research progress on the relationship between IP-10，its gene polymorphism and KD，with the aim of providing references for the pathogenesis，prevention，treatment and prognosis of KD.

Objective:Through comprehensive analysis of symptoms and signs, biochemistry, imaging, and dynamic tests, to explore the diagnosis and differential diagnosis of thyrotropin-secreting pituitary adenoma(TSH adenoma) and syndrome of resistance to thyroid hormone(RTH).Methods:A retrospective analysis was conducted on clinical data from 14 patients who visited the First Affiliated Hospital of Zhengzhou University from July 2016 to September 2022, exhibiting elevated levels of free thyroxine(FT4) and free triiodothyronine(FT3) in the presence of increased TSH.Results:There were 7 cases of TSH adenoma and 7 cases of RTH, with the average age of diagnosis at 40.0 years and 26.6 years, respectively. Thirteen patients showed thyrotoxicosis or occasional palpitation, some with pituitary occupancy manifestations or abnormal growth and development; One patient presented with neck thickening. Sex hormone binding globulin was elevated in 3 cases of TSH adenoma. Pituitary magnetic resonance imaging showed that all 7 cases of TSH adenoma were macroadenomas and 1 case of RTH was microadenoma. The octreotide suppression test in 13 patients was inhibited, but there was a significant difference in the inhibition rate of 24 h/2 h TSH inhibition rate of TSH adenoma and RTH, ranging from 46.6% to 83.9% and 4.6% to 28.8% respectively. Six cases of RTH had thyroid hormone receptor β mutation.Conclusion:Syndrome of inappropriate secretion of thyrotropin is a rare condition, mainly including TSH adenoma and RTH. The diagnosis and differentiation of the two conditions require comprehensive assessment incorporating family history, symptoms and signs, laboratory tests, dynamic test, and genetic test. Among these, the 24 h/2 h TSH inhibition rate of octreotide suppression test can effectively distinguish TSH adenoma from RTH.

【Objective】 To analyze the predictive value of serum β-defensin-3 (HBD-3) and decoy receptor 3 (DCR3) for urinary tract infection after percutaneous nephrolithotomy (PCNL) in patients with complex kidney calculi. 【Methods】 A prospective study was conducted on 112 patients treated with PCNL at our hospital during Jan.2020 and Dec.2022.The patients were divided into the non-infection group (52 cases) and infection group (60 cases).The general data, HBD-3 and DCR3 levels of the two groups were compared.Receiver operating characteristic (ROC) curve was drawn to analyze the predictive value of C reactive protein (CRP), procalcitonin (PCT), HBD-3 and DCR3 levels for postoperative urinary tract infection. 【Results】 Compared with the non-infection group, the infection group had higher levels of HBD-3 [(0.77±0.08) ng/mL vs. (1.36±0.25) ng/mL, P=0.001] and DCR3 [(4.68±0.53) ng/mL vs.(13.21±0.28) ng/mL, P=0.001].Multivariate logistic regression showed that a history of urinary tract surgery, preoperative urinary tract infection, operation time, catheterization time, stone load, type of antibiotics, concomitant renal dysfunction, intraoperative channel type, CRP, PCT, HBD-3 and DCR3 were risk factors of postoperative urinary tract infection (P<0.05).The ROC curve showed that the accuracy of CRP, PCT, and CRP plus PCT were 70.54%, 72.32%, and 78.57%, respectively; the accuracy of HBD-3, DCR3, and HBD-3 plus DCR3 were 69.64%, 75.89%, and 86.61%, respectively. 【Conclusion】 Postoperative urinary tract infection in patients with complex kidney calculi is associated with multiple factors, especially high expression levels of HBD-3 and DCR3.Combined detection has high predictive value.

BACKGROUND:After the treatment of femoral shaft fracture with the intramedullary nail,the third fracture open reduction indications are controversial.Some scholars believe that limited open reduction can achieve anatomical reduction,conducive to fracture healing;but some scholars believe that no open reduction of the third fracture still has a high fracture healing rate. OBJECTIVE:To investigate the effect of the circumference and displacement of the third fragment on fracture healing after intramedullary nailing of femoral shaft fractures with the third fragment. METHODS:A retrospective cohort study was conducted to analyze the clinical data of 142 patients suffered a femoral shaft fracture with a third fragment admitted to the Affiliated Lianyungang Hospital of Xuzhou Medical University from February 2016 to December 2021.The fracture were classified into three types according to the circumference of the third fracture with reference to the diaphyseal circumference at the fracture site:type 1 in 71 cases,type 2 in 52 cases,and type 3 in 19 cases.Referring to the diaphyseal diameter,the fractures were classified into three degrees according to the degree of the third fragment displacement:degree I in 95 cases,degree II in 31 cases,and degree III in 16 cases.All patients were treated with femoral interlocking intramedullary nails,and no intervention was performed for the displaced third fragment during the operation.Postoperative follow-up was performed to compare the fracture healing rate,healing time,and the modified Radiographic Union Scale for Tibia at month 9 after surgery in each group.The effect of third fracture fragment circumference and degree of displacement on fracture healing was assessed. RESULTS AND CONCLUSION:(1)All 142 patients were followed up for at least 12 months,with a mean of(14.7±4.1)months,and the overall healing rate was 73.4%.(2)When the third fragment was displaced by degree I,the healing rate,healing time,and modified Radiographic Union Scale for Tibia score at month 9 were not statistically significant among the three sub-groups of circumference classification.(3)When the third fragments were displaced by degree II or III,the healing rate and healing time were not statistically significant among the three subgroups of circumference classification;the modified Radiographic Union Scale for Tibia score at month 9 in the type 1 group was higher than that in the type 2 and 3 groups(P = 0.017).(4)Logistic regression analysis showed that a greater third fragment displacement and circumference were associated with lower fracture healing rates(P<0.05).(5)These findings indicate that in the treatment of femoral shaft fractures with third fragment by intramedullary nails,when the fracture fragment is displaced to degree I,the circumference size has little effect on fracture healing,and no intervention is required during surgery.When the third fragment is displaced to degree II or III and the circumference of which is type 1,a higher modified Radiographic Union Scale for Tibia score can still be obtained with no intervention of the third fragment.However,when the circumference is of type 2 or type 3,it significantly affects the fracture healing.Consequently,intraoperative intervention to reduce the distance of displacement of the fragment is required to lower the incidence of nonunion.The displacement of the third fracture fragments has a greater impact on fracture healing than their circumference.
