ObjectiveTo investigate the awareness and clinical practice of guidelines for the prevention and treatment of chronic hepatitis B （2022 edition） among clinicians. MethodsFrom July 19 to December 31， 2024， a self-designed electronic questionnaire was distributed via the WeChat mini program to collect related data from 1 588 clinicians nationwide， including their awareness and practice based on 18 questions regarding testing and referral， diagnosis and treatment， and follow-up. ResultsAmong all respondents， only 350 clinicians correctly understood all the updated key points of antiviral indications and treatment for special populations in the 2022 edition of guidelines for the prevention and treatment of chronic hepatitis B， with an overall awareness rate of 22.0%. Only 20% ‍—‍ ‍40% of the patients with positive HBV DNA and an age of >30 years receive antiviral therapy， while 80% ‍—‍ ‍100% of the patients with positive HBV DNA and a family history of hepatitis B cirrhosis or hepatocellular carcinoma receive antiviral therapy. The median follow-up rates at 1 year， 3 years， and 5 years were 67.5% 57.5% and 47.5%，respectively， showing a trend of gradual reduction， which might be associated with the influencing factors such as insufficient time for follow-up management by clinicians， insufficient awareness of the disease among patients， and poor adherence to follow-up. ConclusionThere is a gap between the awareness and practice of guidelines for the prevention and treatment of chronic hepatitis B （2022 edition） among clinicians. It is recommended to further strengthen training and focus on the whole process of “detection， diagnosis， treatment， and management” for patients with chronic hepatitis B in healthcare institutions， in order to promote the implementation of the guidelines.

Jiuwei Xifeng Granules have become a Chinese patent medicine in the market. Because the formula contains Os Draconis, a top-level protected fossil of ancient organisms, the formula was to be improved by replacing Os Draconis with Ostreae Concha. To evaluate whether the improved formula has the same effectiveness and safety as the original formula, a randomized, double-blind, parallel-controlled, equivalence clinical trial was conducted. This study enrolled 288 tic disorder(TD) of children and assigned them into two groups in 1∶1. The treatment group and control group took the modified formula and original formula, respectively. The treatment lasted for 6 weeks, and follow-up visits were conducted at weeks 2, 4, and 6. The primary efficacy endpoint was the difference in Yale global tic severity scale(YGTSS)-total tic severity(TTS) score from baseline after 6 weeks of treatment. The results showed that after 6 weeks of treatment, the declines in YGTSS-TSS score showed no statistically significant difference between the two groups. The difference in YGTSS-TSS score(treatment group-control group) and the 95%CI of the full analysis set(FAS) were-0.17[-1.42, 1.08] and those of per-protocol set(PPS) were 0.29[-0.97, 1.56], which were within the equivalence boundary [-3, 3]. The equivalence test was therefore concluded. The two groups showed no significant differences in the secondary efficacy endpoints of effective rate for TD, total score and factor scores of YGTSS, clinical global impressions-severity(CGI-S) score, traditional Chinese medicine(TCM) response rate, or symptom disappearance rate, and thus a complete evidence chain with the primary outcome was formed. A total of 6 adverse reactions were reported, including 4(2.82%) cases in the treatment group and 2(1.41%) cases in the control group, which showed no statistically significant difference between the two groups. No serious suspected unexpected adverse reactions were reported, and no laboratory test results indicated serious clinically significant abnormalities. The results support the replacement of Os Draconis by Ostreae Concha in the original formula, and the efficacy and safety of the modified formula are consistent with those of the original formula.

OBJECTIVE: This study aimed to explore the association between body mass index (BMI) and mortality based on the 10-year population-based multicenter prospective study. METHODS: A general population-based multicenter prospective study was conducted at four sites in rural China between 2013 and 2023. Multivariate Cox proportional hazards models and restricted cubic spline analyses were used to assess the association between BMI and mortality. Stratified analyses were performed based on the individual characteristics of the participants. RESULTS: Overall, 19,107 participants with a sum of 163,095 person-years were included and 1,910 participants died. The underweight (< 18.5 kg/m ²) presented an increase in all-cause mortality (adjusted hazards ratio [ aHR] = 2.00, 95% confidence interval [ CI]: 1.66-2.41), while overweight (≥ 24.0 to < 28.0 kg/m ²) and obesity (≥ 28.0 kg/m ²) presented a decrease with an aHR of 0.61 (95% CI: 0.52-0.73) and 0.51 (95% CI: 0.37-0.70), respectively. Overweight ( aHR = 0.76, 95% CI: 0.67-0.86) and mild obesity ( aHR = 0.72, 95% CI: 0.59-0.87) had a positive impact on mortality in people older than 60 years. All-cause mortality decreased rapidly until reaching a BMI of 25.7 kg/m ² ( aHR = 0.95, 95% CI: 0.92-0.98) and increased slightly above that value, indicating a U-shaped association. The beneficial impact of being overweight on mortality was robust in most subgroups and sensitivity analyses. CONCLUSION This study provides additional evidence that overweight and mild obesity may be inversely related to the risk of death in individuals older than 60 years. Therefore, it is essential to consider age differences when formulating health and weight management strategies.

Conclusion:Ultrasound-guided lower back quadrate fascia plane block combined with dexmedetomidine can improve the recovery after cesarean section, reduce the pain after delivery and sufentanil dosage, improve the quality of sleep and reduce adverse reactions, and have a good analgesic effect.

Purpose To explore the diagnostic value of beak sign in fetal annular pancreas by analyzing the ultrasonographic features of fetal annular pancreas.Materials and Methods The ultrasound images and clinical data of 13 cases of fetal annular pancreas diagnosed by prenatal ultrasound in Shandong Provincial Maternal and Child Health Hospital from September 2019 to December 2021 and confirmed by surgery after birth were retrospectively analyzed.The degree of duodenal stenosis at the obstruction site was observed,especially whether the angle formed by the intestinal wall could identify the fetal annular pancreas,and the ultrasonic characteristics were summarized and analyzed.Results A total of 13 fetuses with annular pancreas showed double bubble sign,3 cases showed clamp sign,and 7 cases showed beak sign at the end of duodenal dilatation.All the 13 cases underwent surgical treatment after birth,including 2 cases with duodenal atresia and 1 case with atypical intestinal malrotation.All the children had good prognosis after operation.Conclusion By observing the dilated end of duodenum and the relationship with pancreatic head,prenatal ultrasound combined with beak sign and double bubble sign could improve the diagnostic accuracy of fetal annular pancreas,which has significant value in prenatal diagnosis of fetal annular pancreas.

Objective:To investigate the effect of CD8+CD28-T cells on acute graft-versus-host disease(aGVHD)after haploidentical hematopoietic stem cell transplantation(haplo-HSCT).Methods:The relationship between absolute count of CD8+CD28-T cells and aGVHD in 60 patients with malignant hematological diseases was retrospectively analyzed after haplo-HSCT,and the differences in the incidence rate of chronic graft-versus host disease(cGVHD),infection and prognosis between different CD8+CD28-T absolute cells count groups were compared.Results:aGVHD occurred in 40 of 60 patients after haplo-HSCT,with an incidence rate of 66.67％.The median occurrence time of aGVHD was 32.5(20-100)days.At 30 days after the transplantation,the absolute count of CD8+CD28-T cells of aGVHD group was significantly lower than that of non-aGVHD group(P=0.03).Thus the absolute count of CD8+CD28-T cells at 30 days after transplantation can be used to predict the occurrence of aGVHD to some extent.At 30 days after transplantation,the incidence rate of aGVHD in the low cell count group(CD8+CD28-T cells absolute count＜0.06/μl)was significantly higher than that in the high cell count group(CD8+CD28-T cells absolute count ≥0.06/μl,P=0.011).Multivariate Cox regression analysis further confirmed that the absolute count of CD8+CD28-T cells at 30 days after transplantation was an independent risk factor for aGVHD,and the risk of aGVHD in the low cell count group was 2.222 times higher than that in the high cell count group(P=0.015).The incidence of cGVHD,fungal infection,EBV infection and CMV infection were not significantly different between the two groups with different CD8+CD28-T cells absolute count.The overall survival,non-recurrent mortality and relapse rates were not significantly different between different CD8+CD28-T cells absolute count groups.Conclusion:Patients with delayed CD8+CD28-T cells reconstitution after haplo-HSCT are more likely to develop aGVHD,and the absolute count of CD8+CD28-T cells can be used to predict the incidence of aGVHD to some extent.The absolute count of CD8+CD28-T cells after haplo-HSCT was not associated with cGVHD,fungal infection,EBV infection,and CMV infection,and was also not significantly associated with the prognosis after transplantation.

Objective:To analyze the clinical characteristics and prognosis of children with hypodiploid B-cell precursor acute lymphoblastic leukemia(BCP-ALL).Methods:The clinical data of 1 287 children with BCP-ALL admitted to five hospital in Fujian province from April 2011 to December 2020 were retrospectively analyzed.According to the results of chromosome karyotype,all the patients were grouped into hypodiploid subgroup and non-hypodiploid subgroup.The clinical characteristics,early treatment response[minimal residual disease(MRD)on middle stage of induction chemotherapy and end of induction chemotherapy]and long-term efficacy[overall survival(OS)and event-free survival(EFS)]were compared.The prognostic factors of hypodiploid BCP-ALL were further explored.Results:Among 1 287 BCP-ALL patients,28 patients(2.2％)were hypodiploid BCP-ALL.The proportion of patients with white blood cell count(WBC)≥50 x 109/L in the hypodiploid subgroup was significantly higher than that in the non-hypodiploid subgroup(P=0.004),while there was no statistically significant difference in gender ratio,age group at initial diagnosis,and early treatment response between the two groups(all P＞0.05).The 5-year EFS and OS rate of the hypodiploid subgroup were 75.0％(95％CI:66.8％-83.2％)and 77.8％(95％CI:69.8％-85.8％),respectively,which were lower than those of non-hypodiploid subgroup[EFS:79.6％(95％CI:78.4％-80.8％);OS:86.4％(95％CI:85.4％-87.5％)],but the difference was not statistically significant(all P＞0.05).Further subgroup analysis by risk stratification showed that the 5-year EFS and OS rates of the hypodiploid subgroup were significantly lower than those in the low-risk(LR)group[LR group EFS:91.4％(95％CI:88.4％-93.6％),P＜0.001;OS:94.7％(95％CI:92.1％-96.4％),P＜0.001];it was similar to that of BCP-ALL children stratified into intermediate-risk(IR)excluding hypodiploid[IR group EFS:79.4％(95％CI:74.9％-83.2％),P=0.343;OS:87.3％(95％CI:83.6％-90.2％),P=0.111];while was higher than that of EFS in HR group,but the difference was not statistically significant[HR group EFS:58.7％(95％CI:52.6％-64.8％),P=0.178.OS:69.9％(95％CI:63.5％-75.4％),P=0.417].Univariate analysis showed that gender,age,white blood cell count,and MRD on middle stage of induction chemotherapy had no significant impact on OS and EFS;chromosome count＜40 was a risk factor for lower OS(P=0.026),but has no significant effect on EFS;MRD≥0.01％after induction therapy was a risk factor for lower OS and EFS(P=0.002,and 0.001,respectively).Conclusion:Children with hypodiploid BCP-ALL have an intermediate prognosis,and MRD ≥0.01％after induction chemotherapy may be a risk factors for poor prognosis.

Objective:To investigate the function and underlying mechanism of cysteine and glycine-rich protein 2(CSRP2)in neuroblastoma(NB).Methods:The correlation between the expression level of CSRP2 mRNA and the prognosis of NB children in NB clinical samples was analyzed in R2 Genomics Analysis and Visualization Platform.The small interfering RNA(siRNA)targeting CSRP2 or CSRP2 plasmid were transfected to NB cell lines SK-N-BE(2)and SH-SY5Y.Cell proliferation was observed by crystal violet staining and real-time cellular analysis.The ability of colony formation of NB cells was ob-served by colony-forming unit assay.Immunofluorescence assay was used to detect the expression of the proliferation marker Ki-67.Flow cytometry analysis for cell cycle proportion was used with cells stained by propidium iodide(PI).Annexin V/7AAD was used to stain cells and analyze the percentage of cell apoptosis.The ability of cell migration was determined by cell wound-healing assay.The level of protein and mRNA expression of CSRP2 in NB primary tumor and NB cell lines were detected by Western blot and quantitative real-time PCR(RT-qPCR).Results:By analyzing the NB clinical sample databases,it was found that the expression levels of CSRP2 in high-risk NB with 3/4 stages in international neuroblas-toma staging system(INSS)were significantly higher than that in low-risk NB with 1/2 INSS stages.The NB patients with high expression levels of CSRP2 were shown lower overall survival rate than those with low expression levels of CSRP2.We detected the protein levels of CSRP2 in the NB samples by Western blot,and found that the protein level of CSRP2 in 3/4 INSS stages was significantly higher than that in 1/2 INSS stages.Knockdown of CSRP2 inhibited cell viability and proliferation of NB cells.Overexpression of CSRP2 increased the proliferation of NB cells.Flow cytometry showed that the proportion of sub-G1,G0/G1 and S phase cells and Annexin V positive cells were increased after CSRP2 deficiency.In the cell wound-healing assay,the healing rate of NB cells was significantly attenuated after knockdown of CSRP2.Further mechanism studies showed that the proportion of the proliferation marker Ki-67 and the phospho-rylation levels of extracellular signal-regulated kinases 1/2(ERK1/2)were significantly decreased after CSRP2 knockdown.Conclusion:CSRP2 is highly expressed in high-risk NB with 3/4 INSS stages,and the expression levels of CSRP2 are negatively correlated with the overall survival of NB patients.CSRP2 significantly increased the proliferation and cell migration of NB cells and inhibited cell apoptosis via the activation of ERK1/2.All these results indicate that CSRP2 promotes the progression of NB by activating ERK1/2,and this study will provide a potential target for high-risk NB therapy.
