Objective To summarize and analyze the efficacy and influencing factors of second allogeneic hematopoietic stem cell transplantation (allo-HSCT) for acute leukemia relapsing after the first allo-HSCT. Methods Clinical data of 17 patients with acute leukemia who underwent second allo-HSCT at Peking University First Hospital from January 2005 to December 2024 were retrospectively analyzed. Results Among the 17 patients, 7 achieved long-term disease-free survival after second transplantation. The median progression-free survival after successful second transplantation was 7 months (range 8 days to 69 months). The relapse fatality was 24%, and the transplant-related fatality was 35%. Conclusions Second transplantation is an effective treatment for relapsed and refractory acute leukemia, but the relapse fatality and transplant-related fatality remain high. Patient age, time of relapse after the first transplantation and disease status before second transplantation are all factors that affect the efficacy of second transplantation. Younger age, late relapse and complete remission of disease before second transplantation are all beneficial for long-term disease-free survival after second transplantation.

AIM: To investigate the abnormal conditions and change patterns of accommodative facility in patients with different refractive states before and after small incision lenticule extraction(SMILE)surgery.METHODS:A prospective clinical cohort study was conducted. A total of 59 patients(118 eyes)who underwent SMILE surgery and had visual function files established in our hospital from June to December 2023 were randomly selected, including 37 males and 22 females, aged 18-35 years(with an average age of 25.19±5.65 years). According to the preoperative spherical equivalent(SE), they were divided into two groups: the low-to-moderate myopia group(SE≥-6.00 DS)with 40 patients(80 eyes), and the high myopia group(SE<-6.00 DS)with 19 patients(38 eyes). The monocular and binocular accommodative facility before surgery and at 1 wk and 1 mo after surgery were compared, and the changes in accommodative facility before and after SMILE surgery in the two groups of patients were analyzed.RESULTS:All surgeries were completed successfully. In the low-to-moderate myopia group, 33 cases(66 eyes)completed the 1-month follow-up after surgery, with a loss to follow-up rate of 17.5%(7/40). In the high myopia group, 15 patients(30 eyes)completed the 1-month follow-up after surgery, with a loss to follow-up rate of 21.1%(4/19). After SMILE surgery, the uncorrected visual acuity and SE of both low-to-moderate myopia and high myopia were significantly improved(all P<0.05). The accommodative facility of the right eyes in all the patients at 1 mo after surgery was better than that before surgery and at 1 wk after surgery(P=0.002, 0.006), the accommodative facility of the left eyes was significantly increased at 1 mo after surgery than that at 1 wk after surgery(P=0.005), and the binocular accommodative facility at 1 mo after surgery was significantly increased compared with that before surgery(P<0.017). Furthermore, there were statistical significance in accommodative facility of the right eyes in the low-to-moderate group at 1 mo compared with that before surgery and at 1 wk after surgery(P=0.011, 0.004); it was significantly increased in the left eyes at 1 mo after surgery compared with that at 1 wk after surgery(P=0.001), and binocular accommodative facility at 1 mo after surgery was significantly better than that before surgery(P<0.001). Furthermore, there was no statistical significance in the right, left and binocular accommodative facility of patients in the high myopia group(all P>0.017).CONCLUSION: After SMILE surgery, the monocular accommodative facility shows a transient decrease and then exceeds the preoperative level at 1 mo after surgery, and the binocular accommodative facility gradually improves after surgery. SMILE surgery has a positive impact on the monocular and binocular accommodative facility in patients with low-to-moderate myopia, but has no significant impact on the accommodative facility in patients with high myopia. It is of clinical significance to strengthen the detection of monocular and binocular accommodative facility before and after SMILE surgery.

AIM: To analyze the changes in binocular visual function before and after small incision lenticule extraction(SMILE)in patients with different degrees of myopia.METHODS:A prospective non-randomized controlled study was conducted. A total of 94 patients(188 eyes)who visited the refractive outpatient department of the ophthalmology department of the General Hospital of the PLA from June 2022 to June 2023 and voluntarily chose SMILE were consecutively included. They were grouped according to the degree of myopia, including 24 cases(48 eyes)in the low myopia group(-3.00 D

ObjectiveTo investigate the microbiological characteristics of bile in patients with common bile duct stones alone or comorbid with juxtapapillary duodenal diverticula （JPDD）. MethodsA prospective study was conducted among 30 patients with common bile duct stones who were admitted to Department of Gastroenterology， Hebei General Hospital， from January to May 2024， and according to the presence or absence of JPDD， they were divided into JPDD group and simple common bile duct stones group （CBD group）， with 15 patients in each group. Bile samples were collected during endoscopic retrograde cholangiopancreatography， and 16S rRNA microbial sequencing was performed to compare the differences in microbial composition， diversity， and metabolic pathways between the two groups. The independent-samples t test was used for comparison of normally distributed continuous data between two groups， and the Mann-Whitney U rank sum test was used for comparison of non-normally distributed continuous data between two groups； the chi-square test or the Fisher’s exact test was used for comparison of categorical data between two groups. Pearson correlation analysis or Spearman correlation analysis was used to analyze the correlation between clinical indicators and microbial species abundance. ResultsClinical data showed that compared with the CBD group， the JPDD group had significantly greater maximum diameter of stones （10.87±3.42 mm vs 6.80±2.08 mm， t=3.94， P0.01） and common bile duct diameter （14.73±3.95 mm vs 9.67±2.64 mm， t=4.13， P0.01）. The microbiological analysis of the bile showed that Proteobacteria， Bacteroidetes， Firmicutes， and Actinobacteria were the most common phyla in both groups， and Proteobacteria was the dominate phylum in the JPDD group. At the genus and species levels， the JPDD group had higher relative abundances of Escherichia-Shigella， Enterococcus， and Escherichia coli. Alpha diversity was similar between the two groups， and there was a significant difference in beta diversity between the two groups （Adonis test， P0.05）. The LEfSe analysis identified 25 differentially expressed species （LDA2） between the two groups， and the JPDD group had enrichment of 7 flora such as Enterobacter， Enterococcaceae， and Klebsiella， while the CBD group had significant enrichment of 18 flora such as Peptococcaceae， Roseburia， and Alistipes （P0.05）. The correlation analysis showed that Enterococcaceae and Enterococcus significantly enriched in the JPDD group were positively correlated with the diameter of the common bile duct and the maximum diameter of stones （P0.01）， whereas Peptococcaceae， Acinetobacter， and Alistipes with reductions in expression were negatively correlated with the diameter of the common bile duct and the maximum diameter of stones （P0.05）. The enrichment analysis of biliary microbial metabolic pathways showed that there were significant differences between the two groups in 10 metabolic pathways such as cell growth and death， transportation and decomposition， nervous system， biosynthesis of valine， leucine， and isoleucine， and histidine metabolism （P0.05）. ConclusionThe presence of JPDD may lead to alterations in bile microbiota， such as an increase in Enterococcus and a reduction in Roseburia， and specific flora and metabolism can promote the formation of common bile duct stones.

Objective To study the effect of Mycobacterium tuberculosis (Mtb) Pro-Pro-Glu-59 (PPE59) protein on the biological function of Mycobacterium smegmatis (Ms) and the regulation of host cell immune response. Methods PPE59 gene fragment was obtained by PCR amplification, cloned into pALACE, constructed into recombinant pALACE-PPE59 vector, and electro-transformed into Ms. Western blot was applied to analyse PPE59 expression and subcellular localization. The survival of Ms_Vec and Ms_PPE59 under low acid (pH=3 and pH=5) conditions and active surface pressure sodium dodecyl sulfate (SDS) conditions and their intracellular survival in macrophages were analyzed. ELISA was used to detect the cytokine (IL-1β, IL-6, IL-12, TNF-α and IL-10) expression levels of Ms_Vec and Ms_PPE59 infected macrophages. Results PPE59 protein localized to the cell wall of Ms can enhance the acid-resistance and anti-SDS effect of Ms, which is conducive to the survival of Ms in macrophages. PPE59 significantly decreased the secretion levels of pro-inflammatory cytokines (IL-1β, IL-6, IL-12 and TNF-α), and promoted the secretion levels of anti-inflammatory cytokine (IL-10). Conclusion PPE59 enhances the survival ability of Ms under low acid and SDS pressure and promotes its intracellular survival by regulating the cytokine secretion levels.

Objective:To evaluate the relationship between red blood cell distribution width (RDW) and prognosis of patients with hepatocellular carcinoma (HCC) andergoing transcatheter arterial chemoembolization (TACE).Methods:Clinical data of 212 patients with HCC andergoing TACE for the first time in Department of Interventional Radiology, the Affiliated Hospital of Xuzhou Medical University from January 2011 to May 2018 were retrospectively analyzed, including 184 males and 28 females, aged (56.8±11.2) years. Follow-up for survival. X-tile software was used to determine 13.1% as the optimal threshold for preoperative RDW prediction of prognosis, and enrolled patients were divided into a low level group (RDW<13.1%, n=70) and a high level group (RDW≥13.1%, n=142). Aspartate aminotransferase, total bilirubin, albumin, hemoglobin and lipoprotein a, Barcelona clinical liver cancer (BCLC) stage and other indexes were compared between the two groups. Survival analysis was performed by Kaplan-Meier method, survival rate was compared by log-rank test, and the effect of RDW on prognosis was analyzed by Cox regression. Results:The 1-year, 2-year and 3-year cumulative survival rates in RDW high level group were 34.5%, 14.1% and 6.3%, respectively, while those in RDW low level group were 64.3%, 38.6% and 21.4%, respectively, with significant difference ( χ2=23.09, P<0.001). Compared with the low level group, the levels of aspartate aminotransferase and total bilirubin were higher, the levels of albumin, hemoglobin and lipoprotein a were lower, the proportion of portal vein cancer thrombin was higher, and the stage of BCLC was later, with statistical significance (all P<0.05). Cox regression analysis showed that HCC patients with RDW≥13.1%( HR=1.732, 95% CI: 1.223-2.452, P=0.002) had poor survival prognosis after TACE. Conclusion:Preoperative RDW≥13.1% is an independent risk factor for survival after TACE in patients with HCC. RDW has potential predictive value for prognosis of patients with HCC.

The uncertainty of prognosis for chronic diseases is a persistent problem in the medical community.Mechanical attribution such as questioning disease （stubbornness）， equipment （medical and nursing level）， and patients （low compliance）， it is believed that there is a bias in analyzing the deep causes of low compliance on prognosis after breakthrough progress in the treatment of this type of diseases.Taking hepatitis B patients from the perspective of hermeneutics as an example， this paper clarified the reasons for the non-identity of doctor-patient cognition on the problem of doctor-patient communication in health education.Meanwhile， it was found that there is a pre-structure of heterogeneous experience in the ontology of understanding between doctors and patients， which presents inherent limitations， openness， generativity， and external micro power penetration in their history of dialogue logic.Finally， epistemologically， this paper clarified the essence such as the history of identity effect was pointed by the reconstruction of heterogeneous “meaning ideals” of doctors and patients， the understanding of certainty and elimination of subjectivity was guided by meaning ideals under the fusion of horizons， as well as good personalized prognostic behavioral literacy was led by cultivations of embodied practice.

Objective To compare and analyze the application value of domestic Octoparms and imported Celect inferior vena cava filter(IVCF)in the interventional treatment of venous thromboembolism(VTE).Methods Forty patients with VTE were randomly divided into Octoparms group(experimental group)and Celect group(control group)according to the double-blinded method of the central random system.All the patients underwent filter placement,catheter-directed thrombolysis and filter retrieval.The primary end point was the success of filter placement and retrieval,and the secondary end point included indwelling complications such as the occurrence of pulmonary embolism(PE)and filter tilt and migration.Results Forty patients were enrolled in this study,22 patients and 18 patients were divided into the experimental group and the control group,respectively.Among them,11 cases were identified with right lower extremity deep vein thrombosis,29 cases with left lower extremity deep vein thrombosis,17 cases with PE,and 6 cases with inferior vena cava thrombosis.The success rate of IVCF placement was 100%in all participants.Immediately after filter place-ment,the angle of filter tilt was(3.8±2.3)° in the experimental group and(4.9±2.8)° in the control group(t=1.44,P=0.16).Filter retrieval was successful in 21 cases(21/22,95.5%)of the experimental group and 17 cases(17/18,95.5%)of the control group.There was no significant difference between the two groups(t=0.14,P=0.89).The mean indwelling time of filter was(8.0±2.1)days in the experimental group and(9.7±3.1)days in the control group(t=0.73,P=0.47).The angle of filter tilt was(5.3±3.4)° in the experimental group and(5.7±7.7)° in the control group(t=0.19,P=0.85).There was no significant difference for filter placement and retrieval between the two groups(t=0.48 and 2.00,P=0.06 and 0.64,respectively).There were no complications of filter migration,strut penetration or new PE in both groups.Conclusion The application value of domestic Octoparms and impor-ted Celect IVCF is similar in interventional treatment of VTE.

Objective To explore the clinical application of individualized coil embolization in the interventional treatment of renal artery aneurysm(RAA).Methods Data of 23 patients with RAA treated by individualized coil embolization were analyzed.There were 27 RAAs,in which narrow-necked RAAs were treated with coil embolization and wide-necked RAAs were treated with stent-assisted coil embolization.The efficacy of the two embolization methods were analyzed and the changes of renal function and symptoms were observed.Results A total of 27 RAAs in 23 patients were successfully embolized at one time,including 23 narrow-necked RAAs in 19 cases treated with coil embolization and 4 wide-necked RAAs in 4 patients treated with stent-assisted coil embolization.The embolization effect of 20 cases(86.96%)reached Raymond grade Ⅰ,and 3 cases(13.04%)reached gradeⅡ.Postoperative computed tomography angiography(CTA)showed that all parent arteries were patent,the RAA was not visualized,and there was no renal infarction.There was no statistical difference in creatinine values before operation,1 month,6 months and 1 year after operation(P>0.05).In the 12 patients with hypertension,there were statistically significant differences in blood pressure at 1 year after operation compared with preoperative,1 month,and 6 months after operation(P<0.05).The symptoms of low back pain and hematuria disappeared after operation.Conclusion Individualized coil embolization for RAA is safe,effective and worthy of clinical promotion.
