Objective To analyze the effect of Shufeng Tongqiao decoction combined with methylprednisolone tablets in patients with chronic sinusitis and nasal polyp(CRSwNP)after operation.Methods A total of 104 patients with CRSwNP underwent endoscopic nasal surgery were prospectively selected,and patients were randomly divided into the hormone group(n=52,postoperative methylprednone tablets)and the study group(n=52,postoperative combined treatment with Shufeng Tongqin Decoction).After removal and shedding,50 cases were included in the hormone group,and 49 cases were included in the study group.The curative effect,lung wind-heat syndrome score,nasal mucosa recovery(assessed by Lund-Kennedy score system)and nasal mucosa remodeling were compared between the two groups.Serum levels of human β-defensin(HBD)-2 and high mobility group protein B1(HMGB1)were detected by enzyme-linked immunosorbent assay.Results The total control rate was higher in the study group than that of the hormone group(95.92%vs.80.00%,P＜0.05).At 12 weeks after surgery,the lung meridian wind heat syndrome scores,Lund-Kennedy scores and serum HMGB1 level were lower than before surgery in both groups(P＜0.05),and the study group was lower than the hormone group(P＜0.05).At 12 weeks after surgery,the epithelial injury grading was better in the study group than that in the hormone group(P＜0.05),and the basement membrane thickness was thinner than that in the hormone group(P＜0.05).Conclusion The joint of Shufeng Tongqiao decoction and methylprednisolone tablets has a better effect on postoperative CRSwNP patients,and it can greatly improve the levels of serum hBD-2 and HMGB1,effectively inhibit nasal mucosal remodeling,and greatly improve the recovery of nasal mucosa.

Objective To assess the effects of “dual low” scanning technology in conjunction with an individualized injection protocol in enhancing the quality of abdominal contrast-enhanced CT images. Methods A total of 200 patients who underwent abdominal contrast-enhanced CT examinations at the Hainan Western Central Hospital between January 2022 and January 2024 were selected for the study. Using a random number table, participants were randomly assigned to either a control group (n = 100, sub-hypertonic contrast agent + conventional tube voltage + individualized injection protocol) or an observation group (n = 100, isotonic contrast agent + tube voltage of 100 kV + individualized injection protocol). The study compared the impact of these two methodologies on the quality of abdominal contrast-enhanced CT images. Results During the arterial phase, the CT value of the abdominal aorta was significantly higher in the observation group than that in the control group (P < 0.05), suggesting that isotonic contrast agent and low tube voltage more effectively enhanced vascular signal. During the portal vein phase, the CT value was higher and the liver parenchymal noise was lower in the observation group those in the control group (P < 0.05), further validating the advantages of the “dual low” approach during the portal venous phase. The radiation dose was significantly lower in the observation group than that in the control group (P < 0.05), indicating that the “dual low” protocol effectively reduced radiation dose while enhancing patient safety. During the arterial phase, both the abdominal aorta noise and liver parenchymal noise were lower in the observation group than those in the control group (P < 0.05), demonstrating that the “dual low” strategy effectively reduced image noise and enhanced image clarity. The image quality scores were significantly higher in the observation group than in the control group (P < 0.05), indicating that high image quality could be achieved even at reduced radiation doses and contrast agent concentrations. Conclusion The “dual low” scanning technology, combined with an individualized injection protocol, not only effectively enhances the contrast of arteries and veins, reduces image noise, and improves the overall image quality, but also decreases radiation dose and enhances patient safety. Therefore, this technology is worth being widely promoted.

Objective:To investigate the different clinical characteristics and prognosis of patients with diabetic nephropathy (DN) accompanied by IgA deposition diagnosed by renal biopsy.Methods:The study was a retrospective cohort study. Clinical and pathological data of patients diagnosed with DN through renal biopsy in Beijing Anzhen Hospital affiliated to Capital Medical University from January 1, 2010 to March 31, 2023 were retrospectively collected. The clinical and pathological characteristics and prognosis of DN patients with IgA deposition and DN control group patients without IgA deposition were compared. Immunofluorescence staining was used to detect the intensity of galactose-deficient IgA1 (Gd-IgA1) staining in renal tissue of DN patients with DN IgA deposition, and grouping was performed according to whether the staining intensity was≥2+. Enzyme linked immunosorbent assay was used to detect the serum level of Gd-IgA1 in patients. A 50% decrease in estimated glomerular filtration rate (eGFR) from baseline or progression to end-stage renal disease within 5 years was defined as a renal endpoint event, and Kaplan-Meier survival analysis and Log-rank test were used to compare the difference in cumulative incidence of renal endpoint events between two groups of patients.Results:A total of 101 DN patients were enrolled in this study, including 68 males (67.3%) and 33 females (32.7%), with age of (52.2±10.3) years and a median follow-up time of 13.5(4.8, 26.3) months. There were 44 patients with IgA deposition (43.6%) and 57 patients without IgA deposition (56.4%). Compared with DN control group, Kaplan-Meier analysis showed that DN patients with IgA deposition had a higher cumulative incidence of renal endpoint within 5 years ( χ2=6.473, P=0.011). The proportion of positive glomerular Gd-IgA1 (KM55) staining in the DN patients with IgA deposition was 54.5% (24/44), and immunofluorescence examination showed consistent distribution of Gd-IgA1 and IgA in the glomerular mesangial and capillary regions. The serum level of Gd-IgA1 in the glomerular Gd-IgA1 positive patients was significantly higher than that in those negative patients [(6 296.4± 1 535.4) μg/L vs. (4 057.4±1 082.0) μg/L, t=-3.037, P=0.010]. In DN patients with IgA deposition, the age of the subgroup with endpoint events was younger [(42.8±6.9) years vs. (53.3±9.4) years, t=-3.440, P=0.002], the duration of proteinuria was shorter [6.0(1.0, 22.0) months vs. 12.0(10.0, 36.0) months, Z=-2.150, P=0.032], and the proportion of patients with glomerular Gd-IgA1 staining intensity ≥2+ was higher [Fisher'exact test, 30.8%(4/13) vs. 0(0/20), P=0.017]. Kaplan-Meier survival analysis showed that patients with glomerular Gd-IgA1 staining intensity≥2+ had a significantly higher cumulative incidence of renal endpoint events ( χ2=4.846, P=0.028). Conclusion:DN patients with glomerular IgA deposition and Gd-IgA1 positivity may be associated with worse prognosis.

The study was a retrospective study. The clinical data of 866 patients with IgA nephropathy (IgAN) in Beijing Anzhen Hospital, Capital Medical University from March 2010 to March 2021 were analyzed, to investigate the clinical pathology and renal prognosis of IgAN patients with intrarenal arteriolosclerosis, and to preliminarily explore whether abnormal activation of complement system is involved in the injury of arteriolosclerosis. The patients were divided into renal arteriolar lesions group and non-renal arteriolar lesions group according to the renal histopathology, and the differences of clinical pathological manifestations, prognosis between the two groups were compared. The results showed that, compared with the non-renal arteriolar lesions group ( n=236), IgAN patients in the renal arteriolar lesions group ( n=630) had higher proportions of hypertension and malignant hypertension, higher levels of urinary albumin-creatinine ratio, 24-hour urine protein quantification and serum uric acid, lower estimated glomerular filtration rate, and more severe MEST-C lesions of the Oxford classification (all P < 0.05). Cox regression analysis results showed that intrarenal arteriolosclerosis was the independent risk factor affecting the progression of IgAN to ESRD ( HR=6.437, 95% CI 2.013-20.585, P=0.002). Renal histopathology showed that the deposition of complement C3c on the wall of intrarenal arterioles in the renal arteriolar lesions group ( n=98) was stronger than that in non-renal arteriolar lesions group ( n=18, P < 0.05). IgAN patients with renal arteriolosclerosis present with serious clinical and pathological manifestations, and renal prognosis. Abnormal activation of complement system may be involved in the pathogenesis of intrarenal arteriolosclerosis.

Objective: To explore the efficacy and prognostic factors of hematopoietic stem cell transplantation (HSCT) for the treatment of patients with anaplastic large cell lymphoma (ALCL) . Methods: The clinical records of 33 ALCL patients after HSCT were collected and analyzed retrospectively to evaluate the rates of overall survival (OS) and recurrence after autologous (auto-HSCT) and allogeneic HSCT (allo-HSCT) and the factors influencing prognosis. Results: The median-age of this cohort of 33 ALCL cases at diagnosis was 31 (12-57) years old with a male/female ratio of 23/10, 24 cases (72.7%) were ALK⁺ and 9 ones (27.3%) ALK^-. Of them, 25 patients (19 ALK⁺ and 6 ALK^-) underwent auto-HSCT and 8 cases (5 ALK⁺ and 3ALK^-) allo-HSCT with a median follow-up of 18.7 (4.0-150.0) months. Disease states before HSCT were as follows: only 6 patients achieved CR status and received auto-HSCT, 16 patients achieved PR (14 cases by auto-HSCT and 2 ones allo-HSCT) , the rest 11 cases were refractory/relapse (5 cases by auto-HSCT and 6 ones allo-HSCT) . There were 7 cases died of disease progression (5 after auto-HSCT and 2 allo-HSCT) and 5 cases treatment-related mortality (TRM) (2 after auto-HSCT and 3 allo-HSCT) , TRM of two groups were 8.0% and 37.5%, respectively. Both the median progression-free survival (PFS) and OS were 15 months after auto-HSCT, the median PFS and OS after allo-HSCT were 3.7 (1.0-90.0) and 4.6 (1.0-90.0) months, respectively. There was no statistically significant difference in terms of survival curves between the two groups (OS and PFS, P=0.247 and P=0.317) . The 2-year OS rates in auto-HSCT and allo-HSCT groups were 72% and 50%, respectively. The 5-year OS rates in auto-HSCT and allo-HSCT groups were 36% and 25%, respectively. Conclusion ALCL treated by chemotherapy produced high rates of overall and complete responses. Chemotherapy followed by auto-HSCT remained to be good choice for patients with poor prognostic factors. High-risk patients should be considered more beneficial from allo-HSCT.

Objective: To analyze the frequency and composition of risk-related cytogenetic abnormalities (CAs) in patients with newly-diagnosed multiple myeloma (NDMM) . Methods: The frequency and composition of risk-related CAs from a cohort of 1 015 Chinese patients with NDMM were determined by interphase fluorescence in situ hybridization (iFISH) , individually or in combination. Results: Of the cohort of 1 015 Chinese patients with NDMM, the frequencies of IgH arrangement, del (13q) /13q14, 1q gain and del (17p) were 54.0%, 46.4%, 46.1% (35.8% and 12. 7% for 3 or more than 3 copies) and 9.9%, respectively. Among 454 patients who had the baseline information for all risk-related CAs [except t (14;20) , which was not covered by the FISH panels performed routinely at all five centers], the frequencies of t (4;14) , t (11;14) or t (14;20) were 14.1%, 11.2% and 4.8%, respectively; of them, 44.3% patients carried 2 or more CAs (28.0%, 13.4% and 2.9% for 2, 3 or ≥4 CAs) ; 83.3%, 95.0% or 68.6% patients with 1q gain, del (17p) or IgH rearrangement had 1 or more additional CA (s) , with del (13q) /13q14 as the most frequently accompanied CA; 57.7% patients carried at least 1 HRCA; the incidences of double-hit (DH) MM (DHMM) (=2 HRCAs) and triple-hit (TH) (THMM) (≥3 HRCAs) were 14.3% and 2.9%, respectively. Conclusions Our results provided an up-to-date profile of CAs in Chinese NDMM patients, which revealed that approximately 58% patients might carry at least 1 HRCA, and 17% could experience so-called DHMM or THMM who presumably had the worst outcome.

Objective: To evaluate clinical outcomes of autologous (auto-HSCT) and allogeneic hematopoietic stem cell transplantation (allo-HSCT) for angioimmunoblastic T-cell lymphoma (AITL) . Methods: From June 2007 to June 2017, clinical data of AITL patients who underwent HSCT in eight hospitals were assessed retrospectively. Results: Of 19 patients, 13 male and 6 female with a median age of 50 (32-60) years old, 12 auto-HSCT and 7 allo-HSCT recipients were enrolled in this study, all donors were HLA-identical siblings. Two of allo-HSCT recipients were relapsed auto-HSCT ones. There were 5 patients (5/12) in complete response (CR) status and 7 (7/12) in partial remission (PR) status before transplantation in auto-HSCT group, and 2 (2/7) in PR status and 3 (3/7) in progression disease (PD) status before transplantation in allo-HSCT group. The median follow-up for the surviving patients was 46.5 months (range, 1-100 months) for the whole series, two patients lost in auto-HSCT group. Three patients developed acute graft-versus-host disease (aGVHD) and 5 chronic graft-versus-host disease (cGVHD) after allo-HSCT. Three patients died of primary disease and 1bleeding in auto-HSCT group. One patient died of primary disease and 2 transplantation-related mortality in allo-HSCT group. The 3-year cumulative overall survival (OS) were 56% (95%CI 32%-100%) and 57% (95%CI 30%-100%) for auto-HSCT and allo-HSCT, respectively (P=0.979) . The 3-year cumulative progression-free survival (PFS) were 34% (95%CI 14%-85%) and 57% (95%CI 30%-100%) for auto-HSCT and allo-HSCT, respectively (P=0.451) . Conclusion Both auto-HSCT and allo-HSCT were optimal choices for AITL. In clinical practice, which HSCT was better for AITL patients should be based on comprehensive factors including sensitivity to chemotherapy, risk stratification and disease status at transplantation.

Objective To investigate whether the clinical and pathological injury of kidney in IgA nephropathy (IgAN) patients with hypertension is associated with circadian blood pressure rhythm change, particularly with elevated nocturnal blood pressure (BP). Methods This study was a retrospective cross-sectional study. Clinic and renal histopathological injury data were obtained from 83 IgAN patients with hypertension. First, 24 h ambulatory BP monitoring (ABPM) data were analyzed. Second, all these IgAN patients were divided into two groups, elevated nocturnal BP group and nocturnal normotensive BP group, and the clinical and pathological differences between this two groups were analyzed. Third, logistic regression analysis was used to analyze the influencing factors of renal tubulointerstitial injury in IgAN patients with hypertension. At last, all these IgAN patients were divided into two groups according to the level of estimated glomerular filtration rate (eGFR), group of patients with eGFR≥60 ml·min-1·(1.73 m2)-1 and the other group with eGFR<60 ml·min-1·(1.73 m2)-1, and the 24 h ABPM data were compared. Results (1) The proportion of non-dipper circadian rhythm of BP in IgAN patients with hypertension was 79.5％. (2) Compared with nocturnal normotensive BP group, patients in elevated nocturnal BP group had significantly higher levels of 24-hour urinary protein quantity and blood uric acid (both P<0.05), and lower eGFR and urine osmotic pressure clinically (both P<0.05). Index of interstitial fibrosis and tubular atrophy was significantly higher in nocturnal normotensive BP group (P<0.05), while the proportion of glomerular ischemia lesion was not significantly different between two groups. (3) Multivariate logistic regression analysis showed that elevated nocturnal BP was an independent risk factor for severe tubulointerstitial injury of IgAN (OR=1.113, 95％CI 1.038-1.192, P=0.002). (4) Compared with the group of eGFR≥60 ml·min-1·(1.73 m2)-1, 24-hour systolic blood pressure (SBP) and diastolic blood pressure (DBP), daytime SBP and DBP, nocturnal SBP and DBP were significantly higher in group of eGFR<60 ml·min-1·(1.73 m2)-1 (all P<0.05). Conclusion The proportion of non-dipper circadian rhythm of BP in IgAN patients with hypertension is as high as 79.5％. Elevated nocturnal BP is associated with the severity of renal damage, and elevated nocturnal BP is an independent risk factor for severe tubulointerstitial injury in IgAN patients with hypertension. Therefore, 24 h ABPM should be emphasized, and elevated nocturnal BP should be well controlled to slow the progression of IgAN.
