BACKGROUND: Concurrent chemo-radiotherapy (CCRT) is the standard treatment for locally advanced cervical cancer (LACC), but there are still many patients who suffer tumor recurrence. However, valuable predictors of treatment outcomes remain limited. This study aimed to assess the value of the serum immune biomarkers to predict the prognosis. METHODS: We reviewed cervical cancer patients treated with CCRT between January 2014 and May 2018 at Peking Union Medical College Hospital. The systemic immune inflammation index (SII), systemic inflammation response index (SIRI), and lactate dehydrogenase (LDH) were calculated using blood samples. The relationship between immune markers and the treatment outcome was analyzed. The area under the receiver operating characteristic (ROC) curve was used to evaluate the predictive efficiency. The Cox proportional hazards model and log-rank were used to predict overall survival (OS) and disease-free survival (DFS). RESULTS: This study included 667 patients. Among them, 195 (29.2%) patients were defined as treatment failure, including 127 (19.0%) patients with pelvic failure, 94 (14.1%) distant failure, and 25 (3.7%) concurrent pelvic and distant failure. It revealed that the tumor stage, size, metastatic lymph nodes (MLNs), and serum immune biomarkers, such as SII, SIRI, and LDH, were significantly related to treatment outcomes. We demonstrated that the optimal cut-off of the SII, SIRI, and LDH were 970.4 × 10 9 /L, 1.3 × 10 9 /L, and 207.52 U/L, respectively. Importantly, this study presented that LDH level had the highest OR (OR = 4.2; 95% CI [2.3-10.8]). Furthermore, the OS and DFS for patients with pre-SII ≥970.5 × 10 9 /L were significantly worse than those with pre-SII <970.5 × 10 9 /L. Similarly, pre-SIRI ≥1.25 × 10 9 /L and pre-LDH ≥207.5 U/L were related to poor survival outcomes. CONCLUSIONS This study demonstrated that the baseline SII, SIRI, and LDH levels can be used to accurately and effectively predict the treatment outcomes after CCRT and long-term prognosis. Our results may offer additional prognostic information in clinical, which helps to detect the potential recurrent metastasis in time.

ObjectiveTo understand the epidemic characteristics of influenza in Beijing from 2023 to 2024, and to provide a scientific basis for the prevention and control of influenza. MethodsData on influenza-like illness (ILI) from secondary level and above hospitals, etiology surveillance data, and influenza clusters outbreaks data from 2023‒2024 were used to analyze the epidemic trend and pathogenic characteristics of influenza. Furthermore, an influenza comprehensive index was used to categorize the epidemic intensity at the severity level. ResultsA total of 2 065 857 ILI cases were reported in 2023‒2024 epidemic season, and the percentage of ILI was 3.67%. The age group of 5‒14 years accounted for the highest proportion of ILI (30.48%). A total of 41 766 throat swabs from ILI were detected, with a positive rate of 17.28%.A (H3N2) (51.86%) and B Victoria (41.93%) were the most prevalent subtypes of influenza virus. Clustered influenza outbreaks occurred mainly in primary schools (57.78%) and middle schools (35.55%), mainly caused by the influenza A (H3N2) subtype (85.93%). According to the influenza comprehensive index (I), the period of influenza activity and above (I>0.5) lasted for a total of 37 weeks, accounting for 71.15% of the entire influenza season. ConclusionCompared with previous years, the epidemic level of influenza in Beijing was increased in 2023‒2024, and the peak time became earlier. The comprehensive index method can objectively evaluate the level of influenza epidemic and provide suggestions for the future prevention and control of influenza in Beijing.

Objective To discuss the clinical value of echocardiographic indicators in assessing the short-term efficacy of transcatheter aortic valve replacement(TAVR)and surgical aortic valve replacement(SAVR)in treating patients with severe aortic valve stenosis(AS).Methods The clinical data of 70 patients with severe AS,who received treatment at the Daping Hospital of Army Military Medical University of China between June 2019 and September 2022 were retrospectively analyzed.The patients were divided into SAVR group(n=40)and TAVR group(n=30).The preoperative one-week and postoperative one-month echocardiographic indicators were compared between the two groups.Results In both groups,the postoperative one-month peak aortic valve velocity(Vmax),aortic valve mean transvalvular pressure gradient(mPG),relative thickness of chamber wall(RWT),and left ventricular mass index(LVMI)were decreased when compared with preoperative values(all P＜0.05);in TAVR group the left ventricular ejection fraction(LVEF),LVMI and incidence of perivalvular leakage were remarkably higher than those in SAVR group,while the Vmax and mPG were obviously lower than those in SAVR group(all P＜0.05).In TAVR group,the mitral regurgitation decreased from preoperative 12 patients(40％)to postoperative 2 patients(6.7％)and the over-moderate tricuspid regurgitation decreased from preoperative 7 patients(23.3％)to postoperative one patient(3.3％)(all P＜0.05).In SAVR group,the mitral regurgitation decreased from preoperative 15 patients(37.5％)to postoperative 2 patients(5.0％)and the over-moderate tricuspid regurgitation decreased from preoperative 9 patients(22.5％)to postoperative one patient(2.5％)(all P＜0.05).The pulmonary artery hypertension in TAVR group decreased from preoperative 17 patients(56.7％)to postoperative 4 patients(13.3％),which in SAVR group decreased from preoperative 22 patients(55.0％)to postoperative 5 patients(12.5％)(P＜0.05),but the differences in the above indexes between the two groups were not statistically significant(all P＞0.05).Conclusion TAVR and SAVR have similar efficacy in improving secondary valve regurgitation and pulmonary artery hypertension caused by severe AS.TAVR is superior to SAVR in improving postoperative ventricular reverse remodeling and hemodynamics,although the incidence of paravalvular leakage in TAVR is higher than that in SAVR.(J Intervent Radiol,2024,33:479-482)

This study performed to determine whether OX40L overexpressed by recombinant rabies virus(LBNSE-OX40L)can enhance the innate immune response through activation of dendritic cells and thus activate early antibody production.Bone marrow dendritic cells(BMDCs)were extracted from the femur of Balb/c mice and cultured for 6 days,and the cultured BMDCs were infected with the parental virus LBNSE and the recombinant virus LBNSE-OX40L with the multiplicity of infections(MOI)=1.The effect of each virus on the maturation of BMDCs was analyzed by flow cytometry;ELISA was used to detect the expression of innate immunity-related cytokines such as interferon-α(IFN-α)and interleukin-12p40(IL-12p40)in the supernatants of the infected BMDCs.For in vivo study,Balb/c female mice were injected intramuscularly with 106 FFU of parental virus LBNSE and recombinant virus LBNSE-OX40L in both hind limbs,and the inguinal lymph nodes of mice were collected on day 6 after immunization,and the proportion of mature DCs was detected by flow cytometry.The serum was collected on day 6 after immunization,and the content of virus-neutralizing antibody(VNA)was detected by antiviral neutralizing antibody titration.Mouse serum was collected on day 6 after immunization,and virus neutralizing antibody content was measured by titration of antiviral neutralizing antibody,while IgG antibody in mouse serum was detected by ELISA.IgM antibody subclasses were detected by ELISA on days 2,4,and 6 after immunization.Compared with the parental virus LBNSE,the recombinant virus LBNSE-OX40L was able to activate more BMDCs in vitro and produce significantly higher levels of IFN-α and IL-12p40.Furthermore,the recombinant virus LBNSE-OX40L stimulated the maturation and differentiation of the DCs in vivo,which led to the rapid production of high levels of VNA and RABV-specific IgG and IgM antibodies.Taken together,LBNSE-OX40L activates dendritic cells to promote the body's innate immune response,and in turn enhances early antibody production,thus can be an early effective rabies vaccine candidate.

Objective To investigate the value of intravoxel incoherent motion diffusion weighted imaging(IVIM-DWI)in quantitatively evaluating the involved muscle in idiopathic inflammatory myopathies(IIM).Methods Totally,50 patients with clinically diagnosed IIM(IIM group)and 15 healthy controls(control group)were selected for bilateral thigh MRI examination,including IVIM-DWI sequences.The right quadriceps(vastus lateralis,vastus intermedius,vastus medialis,and rectus femoris)of all subjects were selected as region of interest(ROI).Single-exponential and double-exponential analysis were employed to quantitatively measure IVIM-DWI parameters,including apparent diffusion coefficient(ADC),D,f,and D*.Based on T1WI and T2WI fat-suppressed images of the right quadriceps,these muscles were divided into affected and unaffected groups.One-way analysis of variance was used to compare IVIM-DWI parameters between affected group,unaffected group,and control group.Receiver operating characteristic(ROC)curve was performed to analyze the differences in IVIM-DWI parameters among the above groups.Results The D and ADC values were significantly higher in the affected group compared to the unaffected group and the control group(P＜0.001).ROC curve analysis revealed that D and ADC values had moderate diagnostic significance with area under the curve(AUC)of 0.794 and 0.882,respec-tively.The cutoff values for D values and ADC values were 1.63×10-3 mm2/s and 1.44×10-3 mm2/s,respectively.Additionally,MRI follow-up performed one year after treatment in three patients with IIM showed significant resolution of inflammatory edema in thigh muscles,accompanied by a marked decrease in IVIM-DWI parameter values,particularly D values and ADC values.Conclusion The affected muscle in IIM show distinctive diffusion characteristics,and IVIM-DWI parameters,especially D values and ADC val-ues,show a higher diagnostic value for assessing muscle status in IIM.In addition,IVIM-DWI parameters also demonstrate a promis-ing value in the follow-up of IIM,which requires further confirmation in larger cohorts.

Objective:To investigate the current status of maternal body image during pregnancy, mother-infant attachment and postpartum depression and explore the mediating effect of mother-infant attachment on maternal body image during pregnancy and postpartum depression, in order to effectively reduce the incidence of postpartum depression and provide reference and guidance for alleviating depressive symptoms.Methods:A total of 362 pregnant women admitted to obstetric wards in Women′s Hospital of Nanjing Medical University were selected for a cross-sectional investigation by applying the Edinburgh Postnatal Depression Scale, the Body Image in Pregnancy Scale and the Maternal Postnatal Attachment Scale by convenient sampling from July to September 2022. Model 4 in the SPSS macro program PROCESS was used to test the mediating effect of maternal infant attachment between body image and postpartum depression.Results:Totally 362 valid questionnaires were retrieved including 194 individuals aged ≤30 years old and 168 individuals aged >30 years old. The scores of maternal body image during pregnancy, mother-infant attachment and postpartum depression were (89.24 ± 15.56), (71.40 ± 8.05), 7.50 (4.00, 11.00) points.Conclusions:Body image during pregnancy can not only directly predict postpartum depression, but also indirectly predict postpartum depression through the mediating effect of mother-infant attachment. In order to prevent or reduce the occurrence of postpartum depression, nursing staff should carry out intervention research based on influencing the path of postpartum depression from the perspective of positive psychology.

ObjectiveTo determine the syndrome of a rat model of follicular dysplasia induced by Tripterygium glycosides based on prescriptions and investigate the mechanism of traditional Chinese medicine intervention via the adenosine monophosphate-activated protein kinase （AMPK）/mammalian target of rapamycin （mTOR）/hypoxia-inducible factor-1 （HIF-1）/vascular endothelial growth factor （VEGF） pathway. MethodForty-eight rats with regular estrous cycles were randomly assigned into a normal group （n=8） and a modeling group （n=40）. The rats in the modeling group were administrated with Tripterygium glycoside suspension （75 mL·kg^-1） by gavage for 30 days. The modeled rats were assigned into model， Siwutang （3.69 g·kg^-1）， Youguiyin （3.11 g·kg^-1）， Zuoguiyin （7.29 g·kg^-1）， and Guishenwan （10.35 g·kg^-1） groups， with 8 rats in each group. The drug intervention lasted for 14 days. The changes of estrous cycle were detected by Pap staining， and a stereoscope was used to observe the morphology of the ovarian tissue. Hematoxylin-eosin staining was employed to observe the pathological changes and follicle count in the ovarian tissue. Enzyme-related immunosorbent assay （ELISA） was used to measure the levels of follicle-stimulating hormone （FSH）， luteinizing hormone （LH）， and estradiol （E₂） in the serum. Real-time fluorescence quantitative polymerase chain reaction and Western blot were employed to determine the mRNA and protein levels， respectively， of AMPK， mTOR， HIF-1， and VEGF in the ovarian tissue. ResultCompared with the normal group， the model group had a disordered estrous cycle， reduced secondary and mature follicles， increased atretic follicles， elevated FSH and LH levels， lowered E₂ level， up-regulated mRNA and protein levels of AMPK， and down-regulated mRNA and protein levels of mTOR， HIF-1， and VEGF （P<0.01）. Compared with the model group， Guishenwan increased secondary and mature follicles， decreased atretic follicles， lowered the FSH and LH levels， elevated the E₂ level， down-regulated the mRNA and protein levels of AMPK， and up-regulated the mRNA and protein levels of mTOR， HIF-1， and VEGF （P<0.01）. Compared with Guishenwan group， Siwutang， Youguiyin， and Zuoguiyin decreased mature follicles， increased atretic follicles （P<0.01）， elevated the LH （P<0.01） and FSH （P<0.05） levels， and lowered the E₂ level （P<0.05）. In addition， Youguiyin up-regulated the protein level of AMPK （P<0.05） and down-regulated the mRNA levels of mTOR and HIF-1 （P<0.01） as well as the mRNA and protein levels of VEGF （P<0.01）. Siwutang down-regulated the mRNA levels of mTOR and HIF-1 as well as the mRNA and protein levels of VEGF （P<0.05）. Zuoguiyin down-regulated the mRNA level of mTOR and the protein and mRNA levels of VEGF （P<0.05）. ConclusionGuishenwan may improve the ovarian function and promote follicle maturation in a rat model of follicular dysplasia by inhibiting the AMPK/mTOR/HIF-1/VEGF pathway， with the therapeutic effect superior to Zuoguiyin， Youguiyin， and Siwutang. It was hypothesized that this model presented the syndrome of kidney-essence deficiency.
