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: To explore the clinical characteristics, therapeutic responses and prognostic features of E2A-PBX1 fusion gene for childhood acute lymphoblastic leukemia (ALL). METHODS: A total of 837 pediatric patients with ALL who were initially diagnosed in our hospital from July 2010 to November 2017 were retrospectively analyzed, 48 children with positive E2A-PBX1 fusion gene were detected by the real-time quantitative PCR techniques and their data were retrospectively collected for analysis. RESULTS: Among 48 cases with positive E2A-PBX1 fusion gene, there were 26 males and 22 females, with onset ages ranging from 9 months to 13 years old. There were 2 cases (4.2%) in the low-risk group, 32 cases (66.7%) in the intermediate-risk group, and 14 cases (29.1%) in the high-risk group at initial diagnosis. The white blood cell (WBC) counts of 25 cases (53.2%) at initial diagnosis were <50×10⁹/L, 11 cases (23.4%) were (50-100)×10⁹/L, and 11 cases (23.4%) ≥100×10⁹/L. The main immunophenotype was common-B ALL (44 cases, 91.7%). Other leukemia fusion genes such as BCR-ABL1, MLL-AF4, and TEL-AML1 were not observed in this cohort of patients. All patients received the treatment of NPCLC-ALL2008 protocol, and 5 cases (10.4%) occurred poor prednisone response. All the 48 cases achieved complete remission (CR) after the induction treatments. The last follow-up date was April 30, 2023. A total of 5 children relapsed, including 1 case with intermediate risk and 4 cases with high risk. The recurrence rate in the high-risk group was significantly higher than that in the intermediate- and low-risk groups (both P < 0.05). Most relapsed children had elevated WBC counts at initial diagnosis. Among them, WBC counts ≥100×10⁹/L was observed in 4 cases. The recurrence rate among children with WBC counts ≥100×10⁹/L was significantly higher than that with WBC counts <100×10⁹/L (P < 0.01). Four deaths occurred in this cohort, of which 3 died of leukemia recurrence. The 10-year event-free survival rate and 10-year overall survival rate of the 48 children with positive E2A-PBX1 fusion gene were 87.5%±4.8% and 91.7%±4.0%, respectively. CONCLUSION In ALL children with positive E2A-PBX1 fusion gene, those with elevated WBC counts and high risk stratification at initial diagnosis are more likely to experience recurrence. Recurrence is the main cause of death in this group. It is suggested that such kind of children receive more intensive chemotherapy or undergo hematopoietic stem cell transplantation as early as possible to further improve prognosis.

OBJECTIVES: To investigate the role of apelin in regulating proliferation, migration and angiogenesis of bladder cancer cells and the possible regulatory mechanism. METHODS: GEO database was used to screen the differentially expressed genes in bladder cancer tissues and cells. Bladder cancer and paired adjacent tissues were collected from 60 patients for analysis of apelin expressions in relation to clinicopathological parameters. In cultured bladder cancer J82 cells and human umbilical vein endothelial cells (HUVECs), the effects of transfection with an apelin-overexpressing plasmid or specific siRNAs targeting apelin, fibroblast growth factor 2 (FGF2) and fibroblast growth factor receptor 1 (FGFR1) on proliferation and migration of J82 cells and tube formation in HUVECs were examined using plate cloning assay, Transwell assay, and angiogenesis assay; the changes in FGF2 expression and FGFR1 phosphorylation were detected using Western blotting. RESULTS: The expression level of apelin was significantly higher in bladder cancer tissues than adjacent tissues, and bladder cancer cell lines (T24 and J82) also expressed higher mRNA and protein levels of apelin than SV-HUC-1 cells. Apelin expression level in bladder cancer tissues was correlated with tumor invasion, distant metastasis and advanced TNM stages. Apelin knockdown significantly suppressed proliferation and migration of J82 cells and decreased the total angiogenic length of HUVECs. In contrast, apelin overexpression significantly promoted proliferation and migration and enhanced FGFR1 phosphorylation in J82 cells, and increased the total angiogenesis length in HUVECs, but this effects were effectively mitigated by transfection of the cells with FGF2 siRNA or FGFR1 siRNA. CONCLUSIONS High expression of apelin promotes J82 cell proliferation and migration and HUVEC angiogenesis by promoting activation of the FGF2/FGFR1 pathway.

Objective: To evaluate the radiation dose, operational standardization, and image quality of computed tomography (CT) Ningbo City Medical Imaging Cloud Platform, so as to provide references for optimizing the quality of CT examinations. Methods: Six CT devices were randomly selected from the Ningbo City Medical Imaging Cloud Platform. Digital Imaging and Communication in Medicine (DICOM) image data from CT examinations of the head, neck, chest, and abdomen in males aged 36 to 60 years were collected from January 2023 to December 2024. The radiation dose levels were evaluated using the volume CT dose index (CTDIvol) and dose length product (DLP). The coefficient of variation (CV) of CTDIvol and scan length were calculated to assess scan stability. Operational standardization was evaluated using the redundancy rate of scan length and protocol matching degree. Imaging quality was assessed using the signal to noise ratio (SNR) and contrast to noise ratio (CNR). Results: A total of 28 897 DICOM images were collected, including 6 730 axial scans of the skull, 2 778 plain scans of the neck, 15 496 plain scans of the chest, and 3 893 plain scans of the abdomen. The typical values of CTDIvol and DLP radiation doses for the head, neck, and chest were all lower than the diagnostic reference levels. The maximum typical values of CTDIvol and DLP for the abdomen were 22.49 mGy and 941.45 mGy·cm, respectively, which were higher than the diagnostic reference levels. The CV values of CTDIvol and scan length ranged from 14.59% to 37.88% and from 8.27% to 44.96%, respectively. The scan stability of head CT was relatively poor, with CV values ranging from 21.74% to 37.88% and from 12.66% to 44.96%, respectively. The redundancy rate of scan length ranged from 6.02% to 74.40%, and the protocol matching degree ranged from 79.80% to 100.00%. The operational standardization of neck CT was relatively poor, with redundancy rates ranging from 45.70% to 74.40% and protocol matching degrees ranging from 79.80% to 95.36%. The mean SNR and mean CNR of the pulmonary arteries in the chest were relatively high, ranging from 15.81 to 17.65 and from 6.33 to 7.41, respectively. Conclusions The radiation doses from abdominal CT examinations on some CT devices exceed the diagnostic reference levels. The scan stability of head CT examinations and the operational standardization of neck CT examinations represent weak points in quality control. It is recommended to carry out targeted quality control training to enhance the overall quality level of CT examinations.

Gynecological cancer significantly affect the health of women.This review aimed to describe the global patterns and trends in the survival of patients with gynecological cancers.We searched PubMed,Embase,Web of Science,SinoMed,and SEER for survival analyses of cancer registration data of cervical,endometrial,and ovarian cancers published between 1980 and 2022.Globally,the highest 5-year observed survival rate for cervical cancer was 76.5%in Anshan,Liaoning,China(2008-2017).The 5-year observed survival rates of endometrial and ovarian cancers were higher in Finland(1995-1999,82.5%)and Singapore(1988-1992,62.0%).The 5-year relative survival rate of cervical cancer patients was higher in Haining,Zhejiang,China(2011-2014,85.8%).Korea ranked first at 89.0%and 64.5%for endometrial and ovarian cancers,respectively.Survival rates have improved for cervical,endometrial,and ovarian cancers.Patients aged≥75 years and those with advanced-stage disease had the worst 5-year survival rates.Survival rates were better for squamous cell carcinoma in cervical cancer,for endometrial carcinoma and mucinous adenocarcinoma in endometrial cancer,and for germ cell and sex-cord stromal tumors in ovarian cancer.Over the past four decades,the survival rates of gynecological cancers have increased globally,with notable increases in cervical and endometrial cancers.Survival rates are higher in developed countries,with a slow-growing trend.Future studies should focus on improving survival,especially in ovarian cancer patients.

Objective To analyze the changes of B lymphocyte(B cells)subsets in peripheral blood of patients with chronic hepatitis B(CHB)and to explore its clinical significance.Methods Peripheral blood samples were collected from 37 treatment-na?ve CHB patients who were admitted to the Fifth Medical Center of PLA General Hospital from July 2022 to October 2022,and peripheral blood samples collected from 18 healthy individuals who have received the hepatitis B vaccine as healthy controls(HC).The study subjects'clinical indexes such as age,HBV DNA viral load,HBsAg quantification,HBeAg semi quantification,ALT,AST,and AST/ALT ratio were collected.The change characteristics of the frequency,phenotypic and functional markers of peripheral blood B lymphocytes and their subsets were compared between CHB and HC.Using multi-color flow cytometry,and the correlation between them and clinical indexes was analyzed.Results Frequency analysis of each subset of B cells showed that compared with HC,the frequency of total B cells,transitional B cells and naive B cells was decreased(P<0.05),while the frequency of mature B cells,memory B cells,atypical memory B cells and activated memory B cells was increased in CHB patients(P<0.01).And there was no significant difference in the frequency of resting memory B cells between the two groups(P>0.05).The results of functional analysis showed that compared with HC,the expression levels of CD79b on total B cells,mature B cells,memory B cells,naive B cells,activated memory B cells,atypical memory B cells and resting memory B cells in CHB patients were increased(P<0.05).The expression level of programmed cell death protein-1(PD-1)on atypical memory B cells in CHB patients was also higher than that in HC group(P<0.05).The results of correlation analysis showed that the frequency of total B cells in CHB patients was slightly negatively correlated with age(r=-0.39,P<0.05),while the expression of programmed death-1(PD-1)on total B cells,mature B cells,transitional B cells,memory B cells and naive B cells were slightly positively correlated with age(r>0.36,P<0.05).Conclusions Chronic HBV infection leads to depletion of the frequency and function of a portion of B cells in the peripheral blood of CHB patients,and age is a potential risk factor for the decline in humoral immune function in CHB patients.

AIM:To investigate the anti-fibrotic effect of Panax notoginseng saponins(PNS)in arecoline(ANE)-induced oral submucous fibrosis,and to analyze the effect of PNS on nuclear factor E2-related factor 2(Nrf2)/glu-tamate-cysteine ligase catalytic subunit(GCLC)signaling pathway.METHODS:CCK-8 assay was used to evaluate the effects of different concentrations of PNS and arecoline on the survival rate of human immortalized keratinocyte cell line Ha-CaT.The results of CCK-8 were used to select 75 mg/L arecoline,and 25,50 and 100 mg/L PNS as subsequent experi-mental concentrations.The cells were set as blank control group,model group,and low,medium and high doses(25,50 and 100 mg/L)of PNS groups.The protein and mRNA expressions of collagen type I(COL-I),E-cadherin,Nrf2,GCLC and glutathione reductase(GR)in each group were detected by Western blot and RT-qPCR.Immunofluorescence method was used to detect the entry of Nrf2 into the nucleus.Biochemical kits were used to detect the content of glutathione(GSH),nicotinamide adenine dinucleotide phosphate(NADPH)and malondialdehyde(MDA),and superoxide dis-mutase(SOD)activity in each group of cells.DCFH-DA fluorescent probe was used to detect the content of intracellular reactive oxygen species(ROS).RESULTS:Compared with the blank control group,the protein and mRNA expression of COL-I in the model group was up-regulated,and the protein and mRNA levels of E-cadherin,Nrf2,GCLC,nuclear Nrf2 and GR were down-regulated.The content of NADPH,MDA and ROS in the cells increased,and the content of GSH and the activity of SOD was significantly reduced.Compared with the model group,the protein and mRNA expression of COL-I was down-regulated,and the protein and mRNA expression of E-cadherin,Nrf2,GCLC,nuclear Nrf2 and GR were up-regulated in PNS 50 and 100 mg/L groups.Compared with the model group,the content of NADPH,MDA and ROS in cells decreased,and the content of GSH and the activity of SOD was significantly enhanced(P<0.05 or P<0.01).CON-CLUSION:Panax notoginseng saponins have anti-fibrosis effects in HaCaT cells,and their mechanism may be related to the activation of Nrf2/GCLC signaling pathway,thereby resisting oxidative stress and improving oral submucosal fibrosis.

Objective To evaluate the clinical application effect of fracture liaison service(FLS)mode after percutaneous vertebroplasty(PVP)/percutaneous kyphoplasty(PKP)for thoracolumbar fragility fracture.Methods A prospective study was conducted,and 762 patients with thoracolumbar fragility fracture who underwent PVP/PKP in the department of orthopedics in our hospital from January 2018 to May 2021 were included and divided into the control group(374 cases)and the observation group(388 cases)according to the random number table method.Patients in the control group received routine osteoporosis intervention,while the patients in the observation group implemented FLS through Blue Bull Medical Care or Chronic Health APP on the basis of the control group to systematically manage the osteoporosis treatment after discharge.The follow-up lasted for 12 months,and the 8-item Morisky medication adherence scale(MMAS-8)score,pain visual analogue scale(VAS)score,Oswestry disability index(ODI)score and Hamilton depression rating scale(HAMD)score at discharge,and 6 months and 12 months after discharge of the two groups were compared.The incidences of re-fracture and constipation 6 months and 12 months after discharge of the two groups were compared.The Cobb angle and bone mineral density T-value of injured vertebrae 6 months and 12 months after discharge of the two groups were compared.Results There was no statistically significant difference in the MMAS-8 score,VAS score,ODI score or HAMD score at discharge of patients between the two groups(P>0.05).The VAS score,ODI score and HAMD score 6 months and 12 months after discharge in the observation group were lower than those in the control group(P<0.05),the MMAS-8 score in the observation group was higher than that in the control group(P<0.05),and the incidences of re-fracture and constipation in the observation group were lower than those in the control group(P<0.05).There was no statistically significant difference in the Cobb angle of injured vertebrae 12 months after discharge of patients between the two groups(P>0.05).The bone mineral density T-value 12 months after discharge in the observation group was higher than that in the control group(P<0.05).Conclusion The FLS mode can significantly improve the medication compliance of patients,relieve pain,depression and constipation,improve bone mineral density,and significantly reduce the incidence of vertebral re-fracture in patients after vertebral augmentation surgery;however,it has no significant effect on the Cobb angle of injured vertebrae.
