Objective To investigate the significance of renal tubular dysfunction in patients with refractoriness nephrotic syndrome(RNS)and the effect of interference treatment of Valsartan (VAL).Methods 79 cases of RNS and 68 healthy controls were recruited into the study. The 79 patients of RNS were divided randomly into the VAL group and the dipyridam group. On the basis of routine therapy, the VAL group was given VAL(80mg/d),and the dipyridam group taken dipyridam (150mg/d)orally for 12 weeks The glomerular tubular function(u-RBP,α1-MG,β2-MG,mAlb,NAG)were detected and the pathologic changes of tubukinterstitium were observed by using the methods of ELISA, biochemistry and scoring of the pathologic damage of tubulointerstitium before and after 12 weeks of VAL treatment in all of the cases. Results Urinary RBP,α1-MG,β2-MG,mAlb and NAG in all patients with RNS was evidently higher than that in healthy controls(P＜0.01).Those had positive correlations with damages of tubulointerstitium(r=0.436,0.626,0.499,0.668,0.657,P＜0.01).The interference outcome displayed that the excretion rates of urinary series of protein after oral use VAL in treatment group were markedly lower, while the control group had no distinct change. Conclusion There were various injury of tubulointerstitium and the disfiguration of renal tubular function in all cases with RNS. Damages of renal tubular function had positive correlation with tubulointemtitium injury and renal globular injury. Interference treatment with ARB in patients with RNS could improve renal tubular function, which is of great significance in delaying the progress of RNS.

OBJECTIVE: To evaluate image quality of female pelvic computed tomography (CT) scans reconstructed with the adaptive statistical iterative reconstruction (ASIR) technique combined with low tube-voltage and to explore the feasibility of its clinical application. MATERIALS AND METHODS: Ninety-four patients were divided into two groups. The study group used 100 kVp, and images were reconstructed with 30%, 50%, 70%, and 90% ASIR. The control group used 120 kVp, and images were reconstructed with 30% ASIR. The noise index was 15 for the study group and 11 for the control group. The CT values and noise levels of different tissues were measured. The contrast to noise ratio (CNR) was calculated. A subjective evaluation was carried out by two experienced radiologists. The CT dose index volume (CTDIvol) was recorded. RESULTS: A 44.7% reduction in CTDIvol was observed in the study group (8.18 +/- 3.58 mGy) compared with that in the control group (14.78 +/- 6.15 mGy). No significant differences were observed in the tissue noise levels and CNR values between the 70% ASIR group and the control group (p = 0.068-1.000). The subjective scores indicated that visibility of small structures, diagnostic confidence, and the overall image quality score in the 70% ASIR group was the best, and were similar to those in the control group (1.87 vs. 1.79, 1.26 vs. 1.28, and 4.53 vs. 4.57; p = 0.122-0.585). No significant difference in diagnostic accuracy was detected between the study group and the control group (42/47 vs. 43/47, p = 1.000). CONCLUSION: Low tube-voltage combined with automatic tube current modulation and 70% ASIR allowed the low CT radiation dose to be reduced by 44.7% without losing image quality on female pelvic scan.

Objective: A longitudinal mediating model was designed to explore the relationship between sleep chronotype and depressive mood with stressful life events as the mediating variable, so as to provide reference basis for preventing depression in adolescents. Methods: From March (T1) to October (T2) 2022, the Munich Chronotype Questionnaire, and Adolescent Self-rating Life Events Checklist and Center for Epidemiologic Studies Depression Scale were administered in 1 251 middle school students in the first and second grades of a middle school in Meishan, Sichuan Province for a follow up study. Two wave of date on sleep time type, stressful life events, and depressive moods were collected. Results: At T1, the detection rate of depressive mood was 22.5% in adolescents but 27.0% at T2.At the same time point, there were significant positive correlations between chronotype, stressful life events and depressive mood ( r=0.06-0.69, P <0.05). Cross lagged model results showed that early sleep chronotype could significantly predict later depressive mood ( β=0.53, P <0.05), and early depressive mood could significantly predict later sleep chronotype ( β=0.01, P <0.01). Longitudinal mediation model analysis showed that T1 sleep chronotype not only directly affected T2 depressive mood (direct effect value=1.421, 95% CI =0.985- 1.858 , P <0.01), but also affect T2 depressive mood through the partial mediating effects of T2 stressful life events (indirect effect value=1.268, 95% CI =0.810-1.726, P <0.05). Although T1 depressive mood was a direct predictor of T2 sleep chronotype (direct effect value=0.025, 95% CI =0.017-0.032), it was not a direct predictor of T2 sleep chronotype by partial intermediate action of T2 stressful life events (indirect effect value=-0.001, 95% CI = -0.006- 0.004, P >0.05). Conclusions Sleep chronotype can not only directly predict depressive mood of adolescents, but also indirectly affect depressive mood of adolescents through the longitudinal mediating effect of stressful life events. To prevent depression and improve mental health in this population, adolescents should develop the habit of early sleep schedule, and improve their ability to cope with stressful life events.

Objective:To investigate the early efficacy and safety of pomalidomide-based regimen in relapsed/refractory multiple myeloma (MM) in the real world.Methods:The clinical data of 15 patients with relapsed/refractory MM treated with pomalidomide-based regimen who were admitted to Gansu Provincial Hospital from January 2021 to July 2021 were retrospectively analyzed, and the early efficacy and safety were also evaluated.Results:There were 8 males and 7 females, and the median age of onset of 15 patients was 60 years (43-83 years); the median time for the diagnosis of relapse and refractory was 15 months (4-84 months). All 15 patients previously received bortezomib-based treatment regimens, 9 patients previously received lenalidomide treatment, and 7 cases received autologous hematopoietic stem cell transplantation. All patients received pomalidomide-based regimen combined with two-drug or three-drug regimen (pomalidomide combined with bortezomib,daratumumab,bendamustine, dexamethasone, cyclophosphamide or lenalidomide). The median treatment cycle was 2 cycles (2-4 cycles). After 2 cycles of treatment, the therapeutic efficacy was evaluated; the overall response rate was 73% (11/15), including 3 cases of complete remission, 3 cases of very good partial remission, and 5 cases of partial remission. Hematological toxicity occurred in 9 patients, of which 5 cases had grade 3-4 hematological toxicity, 4 cases had grade 1-2 hematological toxicity, and other adverse reactions were mild and tolerable.Conclusion:Pomalidomide-based regimen is effective and safe for relapsed/refractory MM patients.
