OBJECTIVE: To explore the short-term efficacy and adverse reactions of orelabrutinib combined with high-dose methotrexate (HD-MTX) in the first-line treatment of elderly high-risk primary central nervous system lymphoma (PCNSL), as well as the survival of patients. METHODS: Twenty-five elderly patients with high-risk primary central nervous system diffuse large B-cell lymphoma admitted to Fujian Provincial Hospital from June 2016 to June 2022 were enrolled in this study, and complete clinical data from all patients were collected retrospectively, and the cut-off for follow-up was December 2022. 15 patients had received temmozolomide combined with HD-MTX regimen for at least four cycles, sequential lenalidomide maintenance therapy, while 10 patients had received orelabrutinib combined with HD-MTX regimen for at least four cycles, sequential orelabrutinib maintenance therapy. The short-term efficacy and adverse reactions of the two groups of patients after treatment were observed. Kaplan-Meier was used to analyze the progression-free survival (PFS) and time to progression (TTP). RESULTS: The objective response rate (ORR) and 2-year median FPS of orelabrutinib combined with HD-MTX regimen group were similar to the temozolomide combined with HD-MTX regimen group (ORR: 100% vs 66.7%; 2-year median PFS: 16 months vs 15 months, P>0.05). The 2-year median TTP of the orelabrutinib+HD-MTX regimen group was better than that of the temozolomide+HD-MTX regimen group (not reached vs 12 months, P<0.05). There were no significant differences in adverse reactions such as gastrointestinal reactions, bone marrow suppression, liver and kidney damage, cardiotoxicity, pneumonia and bleeding between these two groups (P>0.05). CONCLUSION For elderly patients with high-risk PCNSL, orelabrutinib combined with HD-MTX has reliable short-term efficacy, good safety, and tolerable adverse reactions, which is worthy of clinical promotion.

Objective:To investigate the effect of metformin on the microRNA (miRNA) expression and screen potential target with network pharmacology analysis in patients with type 2 diabetes.Methods:Fifteen patients with new diagnosed type 2 diabetes admitted to our hospital were selected, who received metformin during hospitalization and after discharge. The expression of serum matrix metalloproteinase (MMP)-9, transforming growth factor (TGF)-β1, and myocardial fibrosis related miRNAs were compared before and 6 month after metformin treatment. In addition, gene ontology (GO) and KEGG pathway enrichment analysis were applied to analyze differential expression miRNAs showing statistical significance. Meanwhile, the network figure was established to reflect the target gene messenger RNA (mRNA) corresponding to differentially expressed miRNA.Results:Compared with pre-medication, the serum level of MMP-9 was significantly decreased after treatment ( P<0.05). Besides, the expression of homo sapiens microRNA (hsa-miR)29a-3p, hsa-miR133a-5p, hsa-miR21-5p, hsa-miR30c-5p, and hsa-miR1-3p in patients with type 2 diabetes were dramatically down-regulated by metformin ( P<0.05 or P<0.01). Results of GO analysis and KEGG pathway enrichment analysis showed that differentially expressed miRNAs were mainly concentrated in endoplasmic reticulum lumen, synapse, basement membrane and other cell components. The molecular functions such as Rho GTPase binding and participation in extracellular matrix structural constituent were exerted through biological processes such as collagen catabolic process, regulation of short-term neuronal synaptic plasticity, and axon extension, which were mainly enriched in advanced glycation end products-receptor for advanced glycation end products (AGE-RAGE) signaling pathway in diabetic complications, tumor necrosis factor (TNF) signaling pathway, and Wnt signaling pathway, etc. The outcome of miRNA-mRNA network analysis demonstrated that there were 230 target genes mRNAs corresponding to differentially expressed miRNA. Conclusion:Metformin could play its role in the treatment of type 2 diabetes by down regulating the expression of miRNA, participating in the transduction of related cellular signaling pathways, regulating chromatin, nucleic acid binding, and enzyme activities.

Objective:To explore the correlation between sleep duration and incident diabetes among residents of different ages in Xinjiang region.Methods:A total of 9 541 residents, aged 40 and over in Karamay, Xinjiang were identified by a cluster sampling method. Physical examinations and biochemical test were performed, and the data on sleep duration and lifestyle were obtained using standardized questionnaires. The population was divided into three categories according to sleep duration: insufficient sleep(<6 h), ideal sleep(6-8 h), and long sleep duration(>8 h). They were further divided into 2 subgroups based on age at survey. Those who were younger than 60 years old were defined as the middle-aged group, and the rest as the elderly. Multivariate logistic regression analysis was used to explore the correlation between sleep duration and the risk of diabetes in different age groups.Results:There existed an approximate U-shaped relationship between total sleep duration and fasting blood glucose as well as HbA 1C. Fasting blood glucose and HbA 1C were relatively lower among those with ideal sleep duration. After multivariable adjustment, residents with insufficient sleep revealed a 35% increased risk of diabetes( OR=1.35, 95% CI 1.06-1.71) compared with those with ideal sleep duration. However, the risk of diabetes was not significantly increased in those with long sleep duration( OR=1.04, 95% CI 0.94-1.14). Furthermore, the additive risk of insufficient sleep was only significant in the middle-aged group( OR=1.37, 95% CI 1.02-1.84). Conclusions:Among residents of different ages in Xinjiang region, insufficient sleep is associated with an increased risk of diabetes, which is only significant in the middle-aged group.

Objective:To assess the value of acoustic radiation force impulse (ARFI) elastography in the diagnosis of children with biliary atresia.Methods:A prospective survey of infants with hepatitis syndrome and hyperbi-lirubinemia in Xinhua Hospital Affiliated to Shanghai Jiaotong University School of Medicine from January 2017 to December 2018 was performed.The children with hepatitis syndrome were divided into the biliary atresia group( n=45) and non- biliary atresia group( n=30). Thirty children with hyperbilirubinemia were selected as the control group.Shear wave speed (SWS) of all infants was collected by ARFI ultrasound and compared among 3 groups.Receiver ope-rating characteristic curve(ROC curve) was used to analyze the optimal threshold value for SWS in the diagnosis of biliary atresia. Results:The mean SWS values in the biliary atresia group, non-biliary atresia group and the control group were (1.79±0.29) m/s, (1.26±0.12) m/s and (1.08±0.06) m/s, respectively.Compared with the control group, the mean SWS values in the biliary atresia group and non-biliary atresia group were significantly higher ( t=165.43, 15.75, all P<0.05). The mean SWS value in the non-biliary atresia group was significantly lower than that in the biliary atresia group ( t=90.27, P<0.05). With the non-biliary atresia group as reference, the area under the ROC curve of SWS for diagnosis of biliary atresia was 0.98(95% CI: 0.95-1.00), the optimal threshold was 1.45 m/s, and the sensitivity and specificity were 88.9% and 96.7%, respectively. Conclusions:Rapid non-invasive ARFI elastography is effective in the diagnosis of biliary atresia, and thus has important value for early diagnosis and treatment in clinical practice.

The aim of this study was to evaluate the safety and immunogenicity of the first domestic ACYW135 meningococcal conjugate vaccine and a control vaccine named AC group meningococcal conjugate vaccine for 3 months (90-119 days) infants. From February 2017 to June 2018, a randomized, blinded, and similar vaccine-controlled clinical trial design was adopted at the Henan Vaccine Clinical Research Base. The subjects were 3 months old healthy infants, a total of 720, based on a 1∶1 ratio. The random allocation table for entry was randomly assigned to the experimental group and the control group. According to the 3, 4, and 5 month-old vaccination procedures, the subjects were vaccinated with test vaccine (ACYW135 group meningococcal conjugate vaccine) and control vaccine (group A group C meningococcal polysaccharide conjugate vaccine), of which 720 were given the first dose, 696 were given the second dose (test group: 346; control group: 350), and 692 were given the third dose (test group: 344; Control group: 348). The overall adverse reaction rate of the test vaccine was 21.90% (230 cases), which was lower than the 32.04% (339 cases) of the control vaccine (<0.001). The incidence of systemic adverse reactions was 19.52% (205 cases), which was lower than that of the control vaccine (27.69%) (293 cases) (<0.001). The local adverse reaction rate was 3.04% (32 cases), which was lower than the control group (7.84%) (83 cases) (<0.001). The graded adverse reaction test vaccine was 0.57% (6 cases), which was lower than the control group of 2.36% (25 cases) (<0.001). The positive conversion rate of anti-bacterial serum antibodies showed that there was no significant difference between the test vaccine group A (91.42%), C (88.76%) and the control vaccine (92.92%) (87.02%) (>0.05). Group Y and W135 was 88.17% (298 cases), 99.41% (336 cases), respectively. The GMT results showed that the test vaccine group A was 56.24, the control vaccine was 57.43 (>0.05); the group C test vaccine (43.53) was higher than the control group (27.28) (<0.001). The group Y and W135 are 89.22 and 140.66, respectively. Among them, the proportion of the group C GMT antibody ≥ 1∶128 for test vaccine (31.07%, 105 cases) was higher than the control vaccine (16.22%, 55 cases) (<0.001). ACYW135 group meningococcal conjugate vaccine has more safety and immunogenicity after application to 3 month old infants.

OBJECTIVETo investigate the antimicrobial resistance status and pulsed field gel electrophoresis (PFGE) patterns of Salmonella Enteritidis (S.Enteritidis) strains in Henan province.

METHODSS. Enteritidis strains were isolated from seven sentinel hospitals from March 2011 to December 2013. According to molecular typing and Salmonella (Kirby-Bauer, K-B) drug susceptibility testing method published by the international PulseNet bacterial infectious disease monitoring network and USA Clinical and Laboratory Standards Institute (CLSI), we analyzed drug sensitivity of 8 kinds antibiotics and PFGE molecule characteristics of 120 S. Enteritidis isolates from seven sentinel hospitals.

RESULTSAmong 120 strains of S. Enteritidis, 77 were isolated from male patients, 43 from female patients. A total of 78 strains S. Enteritidis were isolated from young children ranged from 0 to 5 years old (65.0%), including 57 strains isolated from 6 months to 2 years old (47.5%). The isolated time mainly centralized on May to October of the year, 11 strains isolated in March-April (9.2%), 48 were in May-July (40.0%),54 in August-October (45.0%), 7 in other months, with a typical summer seasonal characteristics. The resistance rate of 120 strains S. Enteritidis to ampicillin was 50.0% (n=60); to ceftazidime was 14.2% (n=17), to cefotaxime was 18.3% (n=22); to cefepime was 5.8% (n=7); to nalidixic acid was 61.7% (n=74); to ciprofloxacin was 8.3% (n=10), to norfloxacin was 5.8% (n=7); to gentamicin was 42.5% (n=51); to streptomycin was 21.7% (n=26); to chloramphenicol was 30.0% (n=36); resistance to methicillin benzyl ammonium was 11.7% (n=14), compound sulfamethoxazole resistance rate was 71.7% (n=86); the tetracycline resistant rate was 47.5% (n=57). All 120 strains of S. Enteritidis had different levels of resistance to 8 kinds of antibiotics, all strains were multidrug resistant strains, 28 isolates were resistant to 3-4 kinds of antibiotics (23.3%), 38 isolates were resistant to 5-6 kinds of antibiotics (31.7%), 39 isolates were resistant to 7-8 kinds of antibiotics (32.5%). All 120 strains of S. Enteritidis were divided into 44 molecular patterns by digestion with XbaI and pulsed field gel electrophoresis. each pattern contained 1-35 strains with similarity ranged from 54.3%-100%. EN14 and EN19 were the main PFGE types, including 35 and 29 strains respectively.

CONCLUSIONThe status of drug resistance of clinical isolates of Salmonella in Henan province was rather serious, PFGE patterns showed advantages and partial strain's corresponding resistant spectrum have certain relevance and the same aggregation relationship.
