Objective: To explore the correlation between traditional Chinese medicine (TCM) constitution and depressive symptom among school aged children and adolescents, so as to provide evidences for informing constitution based regulation and prevention of depressive symptom. Methods: From June to December 2024, a total of 4 729 students aged 6-14 were recruited by cluster random sampling from 10 primary schools in Baoding (Hebei Province), Heze and Liaocheng (Shandong Province). General information, TCM constitution and depressive symptom were collected. Restricted cubic spline (RCS) models were used to analyze related factors and threshold effects of depressive symptom. Binary Logistic regression was applied to examine the association between depressive symptom and TCM constitution, with subgroup analyses conducted. Results: The detection rate of depressive symptom among the included children and adolescents was 25.82%. RCS analyses indicated non linear associations between depressive symptom and age (inflection point at 10 years old), bedtime (inflection point at 22:00), and wake up time (inflection point at 6:30 ) (all P non linearity <0.01). Linear associations were observed with body mass index (BMI) and sleep duration (all P non linearity > 0.05 ). After adjusting for covariates such as age, BMI and sleep status, binary Logistic regression analyses showed that Yin deficient constitution ( OR =1.26, 95% CI =1.09-1.45) and Phlegm-dampness constitution ( OR =1.42, 95% CI =1.11-1.82) were significantly associated with depressive symptom among children and adolescents (all P <0.05). Conclusions Depressive symptom among school aged children and adolescents is primarily associated with Yin deficiency and Phlegm dampness constitutions in TCM constitution. Active attention should be paid to susceptible TCM constitution among children and adolescents. Targeted health guidance and interventions should be implemented to improve TCM constitution health status for preventing the occurrence of depressive symptom.

Objective:To investigate the clinicopathological features and the prognosis of IgA nephropathy (IgAN) in children with massive proteinuria.Methods:It was a retrospective cohort study. Clinical data of IgAN children with massive proteinuria admitted to the Department of Nephrology, Children's Hospital Affiliated to Capital Institute of Pediatrics from January 2008 to December 2021 were retrospectively analyzed. Patients were divided into effective group and ineffective group according to whether urine protein turned negative after 6 months of initial treatment. The follow-up endpoint event was defined as a reduction in proteinuria of less than 50% or end-stage renal disease (ESRD) achievement. MedCalc software was used to perform Kaplan-Meier survival analysis, and Log-rank test was used to compare the difference of renal survival between the two groups.Results:A total of 127 patients were diagnosed as primary IgAN by renal biopsy, of whom 57 patients with IgAN showed massive proteinuria. These 57 IgAN patients with macroproteinuria accounted for 44.9% of the total IgAN patients and were enrolled in the study. Among the 57 cases, 33 cases (57.9%) were Lee's grade Ⅲ, 11 cases (19.3%) were below Lee's grade Ⅲ, and 13 cases (22.8%) were above Lee's grade Ⅲ. The follow-up time was 4.0 (3.0,5.8) years. In the initial treatment, among 57 patients, 46 (80.7%) were effective (effective group) and 11 (19.3%) were ineffective (ineffective group). Compared with the effective group, the ineffective group had a higher proportion of concurrent AKI at the onset of disease and longer recovery time of renal function, with significant difference (7/11 vs. 13/46, χ2=4.878, P=0.027). Compared with the effective group, the proportion of Lee grade Ⅲ or above was higher in the ineffective group, and the difference was statistically significant (5/11 vs. 8/46, χ2=3.971, P=0.046). There were significant differences in endocapillary hypercellularity (E1), segmental glomerulosclerosis or adhesion (S1) and cellular/fibrocellular crescents (C2) of Oxford classification between IgAN children with Lee grade Ⅲ or below and those over Lee grade Ⅲ (11/13 vs. 20/44, χ2=6.204, P=0.013; 12/13 vs. 17/44, χ2=11.566, P=0.001; 9/13 vs. 7/44, χ2=14.131, P=0.001). Among 57 patients, endpoint events occurred in 2 patients who both were urinary protein unmitigated, and none of the children progressed to ESRD. There was no significant difference in cumulative renal survival between the two groups by Kaplan-Meier survival analysis and Log-rank test ( χ2=0.537, P=0.460) after addition of calcineurin inhibitors (CNIs) to the initial treatment ineffective group. Conclusions:Macroproteinuria is the prominent manifestation of IgAN in children. The pathological type is mainly Lee grade Ⅲ. Children with macroproteinuria have a good prognosis in the short and medium term after active treatment. For IgAN with macroproteinuria that does not respond well to initial treatment, AKI is more common at onset, and renal function recovery time is longer. The application of CNIs may have a certain effect on improving the renal outcome of IgAN with massive proteinuria.

Objective:To investigate the feasibility of construction of rat models of psoriasis-like lesions by using interleukin (IL) -23/T-helper 17 (Th17) axis-related cytokines combined with imiquimod.Methods:A total of 110 Wistar rats were randomly divided into normal control group, imiquimod alone group, imiquimod combined with interferon (IFN) -α2a (180 000, 60 000, 20 000 IU/kg) groups, imiquimod combined with tumor necrosis factor (TNF) -α (45 000, 15 000, 5 000 IU/kg) groups, and imiquimod combined with IL-2 (90 000, 30 000, 10 000 IU/kg) groups, and there were 10 rats in each group. After hair removal from the central area (2 cm × 2 cm) of the rat back, rats in the imiquimod alone group were topically treated with imiquimod 5% cream at a dose of 20 mg/cm 2 on the shaved back; rats in the imiquimod combined with different cytokine groups were treated with topical imiquimod 5% cream at the same dose on the shaved back for 15 minutes followed by intraperitoneal injections of cytokines at corresponding doses once a day for 10 consecutive days. During the treatment, skin lesions on the rat back were evaluated by using the psoriasis area and severity index (PASI) scores every day. On day 10, serum samples were collected from the rats after anesthesia, and enzyme-linked immunosorbent assay (ELISA) was performed to detect levels of IL-17A, TNF-α, IL-23, IFN-α and IL-1β in the serum samples in each group; then, the rats were sacrificed, lesional skin tissues on the rat back were taken for histopathological examinations and evaluated by Baker scores; an immunohistochemical study was conducted to determine the expression of CD4 and CD8 in some skin lesions. One-way analysis of variance was used for comparisons among multiple groups, and least significant difference (LSD) - t test for multiple comparisons; for data with heterogeneous variance, the Kruskal-Wallis H test was used. Results:On day 3 after molding, the rats in the imiquimod alone group and combination groups gradually presented with psoriasis-like skin manifestations, such as erythema, scales and epidermal thickening; the PASI scores reached a peak on day 7 in the imiquimod alone group, and on day 6 in the combination groups. On day 10, histopathological examination of the skin lesions in the imiquimod alone group and combination groups both showed different psoriasis-like pathological features, such as hyperkeratosis, parakeratosis, acanthosis, thinning or disappearance of the granular layer. There were significant differences in the PASI scores and Baker scores among the normal control group, imiquimod alone group and combination groups ( H = 43.33, F = 42.15, both P < 0.001). The PASI scores were higher in the imiquimod combined with IFN-α2a (180 000 IU/kg) group and the imiquimod combined with IL-2 (90 000 IU/kg) group (9.4 ± 1.1, 8.8 ± 0.6, respectively) than in the imiquimod alone group (7.5 ± 1.1, P = 0.002, 0.030 respectively) ; the Baker scores were higher in the imiquimod combined with IFN-α2a (180 000, 60 000 IU/kg) groups, the imiquimod combined with TNF-α (45 000 IU/kg) group, and the imiquimod combined with IL-2 (90 000 IU/kg) group than in the imiquimod alone group (all P < 0.05). The serum levels of TNF-α, IL-17A, IL-1 β and IL-23 significantly differed among groups ( F = 128.97, F = 6.90, H = 27.45, H = 21.10, all P < 0.05). Compared with the imiquimod alone group, the IL-17A level significantly increased in the imiquimod combined with IL-2 (30 000 IU/kg) group (5.54 ± 1.78 pg/ml vs. 4.20 ± 1.14 pg/ml, P = 0.009), and the IL-23 level significantly increased in the imiquimod combined with IL-2 (90 000 IU/kg) group (37.89 ± 32.85 pg/ml vs. 8.56 ± 6.08 pg/ml, P = 0.036). Immunohistochemical study showed significant differences in the expression of CD4 and CD8 in skin lesions among all groups ( F = 7.21, H = 18.32, both P < 0.001), and the expression of CD4 and CD8 in skin lesions was significantly higher in the imiquimod combined with IL-2 (90 000 IU/kg) group than in the imiquimod alone group ( t = -2.46, -2.32, respectively, both P < 0.05) . Conclusion:Imiquimod combined with IFN-α2a or IL-2 could promote the occurrence of psoriasis-like skin lesions in rats, aggravate the development of psoriasis and prolong the maintenance time of the rat models.

Objective:To summarize the effect of reverse homodigital dorsal thumb flap in repairing thumb pulp defect.Methods:A retrospective case series study was conducted to analyze the clinical data of patients with thumb pulp defects admitted to the People's Hospital of Renqiu from March 2010 to June 2020. The dorsal homodigital island flap of the proximal phalanx was designed and harvested. During the procedure, the proximal digital artery of the perforator vessels of the flap was cut off and ligated. The digital artery pedicled flap was retrograde transferred to cover the thumb pulp defect. 9-0 line was used to anastomose the dorsal digital nerve with the proper digital nerve. The donor site was repaired with a free skin graft.Results:A total of 68 cases of thumb pulp defects were enrolled, all of whom were accompanied by exposure of the tendon of the distal phalanx. There were 39 males and 29 females, aged from 18 to 63 years (average of 35.8 years). The size of the proximal dorsal island flap was 2.0 cm × 3.0 cm to 3.1 cm × 4.2 cm. All flaps and skin grafts survived, and wounds healed primarily. All patients were followed up for 6 to 28 months (mean, 10.6 months). The color, texture, and contour of the flaps were good. All repaired thumbs got the normal function of extension and flexion. At the last follow-up, the two-point discrimination of flaps was 4-11 mm.Conclusions:It has the advantages of small trauma, simple operation, and good curative effect, using the homodigital dorsal thumb flap to repair the thumb pulp defect.

Objective:To investigate the therapeutic effect of reverse proximal segment dorsal flap of radial digital artery of the thumb in repairing thumb tip defects.Methods:A retrospective case series study was conducted to analyze the clinical data of 56 patients with thumb tip defects admitted to Renqiu People 's Hospital from February 2010 to October 2020. There were 37 males and 19 females，aged 17-66 years［（37.8±12.2）years］. The injury on the right side was observed in 35 patients and on the left side in 21 patients. All of them were thumb tip defects with exposed distal phalanx. Dimension of skin defects was 2.9 cm×1.8 cm-3.3 cm×2.6 cm.The reverse proximal segment dorsal flap of thumb radial digital artery was used，with the dorsal digital nerve sutured with the proper digital nerve. The donor site was repaired with free skin graft from the ulnar side of the affected forearm. The time of flap harvesting，operation time and healing of the flap were measured. At the last follow-up，the shape，texture，sensory recovery and complications of the flap were observed. One month after operation and at the latest follow-up，the upper limb function evaluation standard set up by hand surgery branch of Chinese Medical Association and Vancouver Scar Scale（VSS）score were used to evaluate the recovery of sensory function of the flap and scar formation of the donor sites，respectively. Results:All patients were followed up for 6-26 months［（13.2±6.4）months］. The time of flap harvesting ranged from 20 to 35 minutes［（26.0±5.3）minutes］. The operation time was 1-2 hours［（1.3±0.3）hours］. Blisters appeared at the distal end of the flap in 2 patients after operation，but they were not treated. After 7 days，the blisters subsided and the flaps survived. The other flaps survived successfully. The donor sites healed by first intention. At the last follow-up，the flaps showed relatively cosmetic appearance，similarities in texture，elasticity and color to the surrounding area and good sensory recovery，without scar contracture and dystrophy of interphalangeal joint. According to the upper limb function evaluation standard set up by hand surgery branch of Chinese Medical Association，56 patients exceeded S3 grade compared to none at postoperative 1 month（ P<0.01），and the VSS score was 3-7 points［（5.0±1.4）points］compared to 6-12 points［（8.8±1.5）points］at postoperative 1 month（ P<0.01）. The donor site left a linear scar，which had no significant effect on its shape and function. Conclusion:The reverse proximal segment dorsal flap of the radial digital artery of the thumb can be used to repair thumb tip defects，for it has advantages of easy operation，a high survival rate as well as good appearance and sensory function recovery，with less damage to the donor area.

Objective:To report our clinical efficacy of pedicled transplantation of proximal thumb dorsal transverse flap to repair tissue defects at thumb pulp and fingertip.Methods:From February 2010 to November 2020, 97 patients with tissue defects at thumb pulp and fingertip were treated by pedicled transplantation of proximal thumb dorsal transverse flap at Department of Orthopedics, People's Hospital of Renqiu. They were 55 men and 42 women, aged from 17 to 66 years (average, 41.3 years). Altogether 55 right and 42 left sides were affected. The size of soft tissue defects ranged from 2.8 cm×1.8 cm to 3.9 cm×2.8 cm. Postoperatively, flap survival, shape, color and sensory recovery at the recipient area were observed; wound healing, function and complications at the donor site were also observed.Results:All the 97 flaps survived and all the wounds healed at the first stage. Blisters appeared at the distal end of the flap in only 2 cases but subsided 7 days after operation with no special treatment and the flaps survived smoothly. All the skin grafts at the donor site survived uneventfully. The 97 patients were followed up for 6 to 26 months (average, 10.7 months). Their flaps were not swollen, finger abdomen was full, finger appearance satisfactory, and finger feeling recovered well. The two-point discrimination at the last follow-up ranged from 4 to 11 mm (average, 7.6 mm). By the trial criteria for assessment of upper limb function suggested by Hand Surgery Society of Chinese Medical Association, sensory function of the affected finger was assessed as S 4 in 21 cases and as S 3+ in 76 cases at the last follow-up. No scar contracture was observed at the donor site and no movement restriction at the interphalangeal joint. Conclusion:Proximal thumb dorsal transverse flap is a reliable choice for reconstruction of complex tissue defects at thumb pulp and fingertip because of the advantages of easy harvest, constant vascular anatomy, full appearance and good sensory function at the recipient site, and limited damage to the donor site.

Objective:To explore the related factors of poor prognostis in children with Henoch-Sch?nlein purpura nephritis (HSPN), and provide reference for predicting and improving the prognosis of children with HSPN.Methods:The clinical and pathological data of children with HSPN hospitalized in the Department of Nephrology, Children's Hospital Affiliated to Capital Institute of Pediatrics from May 2007 to June 2019 were retrospectively reviewed. According to the prognosis, the patients were divided into complete remission group and persistent abnormal group.Results:(1) Among 108 cases, there were 73 males and 35 females, with the onset age ranging from 5 to 16 years and average age of (9.5±2.8) years. The interval time from the first clinic in our hospital to the last follow-up was 2-131 months, with average of 24.8 months. Renal involvement occurred in the course of Henoch-Sch?nlein purpura from 1 day to 51 months, and the renal biopsy time was 5 days to 60 months after renal involvement. (2) Hematuria with proteinuria type and nephrotic syndrome type were predominant, and there was no significant difference between the two groups. The proportion of gross hematuria in the persistent abnormal group were significantly higher than that in the complete remission group (52.6% vs 31.4%, χ2=4.659, P=0.031). There were significant differences in serum creatinine and urea between the two groups (both P<0.05). The proportion of hyperuricemia in the persistent abnormal group was higher than that in the complete remission group (39.5% vs 21.4%, χ2=3.998, P=0.046). After clinical treatment, though there was no significant difference in proteinuria between the two groups at the beginning of the disease, the negative transformation rate of proteinuria in the complete remission group was higher than that in the persistent abnormal group after 3 months (55.7% vs 34.2%, χ2=4.562, P=0.033). (3) According to International study of Kidney Disease in Children (ISKDC) pathology classification, 14 cases (36.8%), 21 cases (55.3%), 3 cases (7.9%) withⅡ, Ⅲ, Ⅳ level in the persistent abnormal group and 21 cases (30.0%), 49 cases (70.0%), 0 case with Ⅱ, Ⅲ, Ⅳ level (70.0%) in the complete remission group after (20.16±24.86) months of follow-up, and the difference between the two groups was not statisticcally significant ( Z=-0.135, P=0.892). According to the Oxford Classification of IgA nephropathy, 36(33.3%) children had tubule-interstitial lesions (T1, 26%-50% tubular atrophy or interstitial fibrosis), and the proportion in the persistent abnormal group was significantly higher than that in the complete remission group (50.0% vs 24.3%, Z=-2.695, P=0.007). (4) Compared with T0 (0-25% tubular atrophy or interstitial fibrosis), the incidence of gross hematuria and hyperuricemia in the T1 tubule-interstitial lesion were both higher than that (respectively 63.9% vs 27.8%, χ2=13.061, P<0.001; 38.9% vs 22.2%, χ2=3.983, P=0.046). (5) Multivariate logistic regression analysis showed that renal tubule-interstitial lesion was a risk factor for poor prognosis of HSPN ( OR=2.580, 95% CI 1.055-6.310, P=0.038). Conclusions:Renal tubule-interstitial lesion is a risk factor for the persistent abnormal of HSPN. Gross hematuria and hyperuricemia are related to tubule-interstitial lesions.

Objective: To explore the effects of checklist for nursing handover in emergency department. Methods: A total of 48 emergency department nurses were recruited by convenient sampling method. We implemented nursing bedside handover checklist four months, the quality of the nursing handover and nurses′ mastery of the patients′ condition and the patients′ satisfaction were compared before and after the implementation. Results: After four-month intervention, the score of the nursing handover quality increased from 60.39±3.22 to 67.73±3.09, the difference was statistically significant (t=-14.377, P<0.01). The score of the nurses′ mastery of the patients′ condition increased from 23.89±2.34 to 27.08±1.82, and there was significant difference (t=-7.287, P<0.01). Patients′ satisfaction improved from 91.163% (111/121) to 96.67% (116/120), the difference was statistically significant (χ²=10.66, P<0.05). Conclusions Implementation of nursing bedside-handover checklist in emergency department can reduce individual cognitive defects, decrease the information missing of the nursing handover,improve the quality of nursing work and ensure the safety of patients.

BACKGROUND/AIMS: The Rome III criteria separated chronic constipation into functional constipation (FC) and constipation-predominant irritable bowel syndrome (IBS-C), but some researchers questioned the partitioning and treated both as distinct parts of a continuum. The study aims to explore the similarity and diversity of brain white matter between FC and IBS-C. METHODS: The voxel-wise analysis of the diffusion parameters was used to quantify the white matter changes of female brains in 18 FC patients and 20 IBS-C patients compared with a comparison group with 19 healthy controls by tract-based spatial statistics. The correlations between diffusive parameters and clinical symptoms were evaluated using a Pearson’s correlation. RESULTS: In comparison to healthy controls, FC patients showed a decrease of fractional anisotropy (FA) and an increase of radial diffusivity (RD) in multiple major fibers encompassing the corpus callosum (CC, P = 0.001 at peak), external capsule (P = 0.002 at peak), corona radiata (CR, P = 0.001 at peak), and superior longitudinal fasciculus (SLF, P = 0.002 at peak). In contrast, IBS-C patients showed FA and RD aberrations in the CC (P = 0.048 at peak). Moreover, the direct comparison between FC and IBS-C showed only RD differences in the CR and SLF. In addition, FA and RD in the CC were significantly associated with abdominal pain for all patients, whereas FA in CR (P = 0.016) and SLF (P = 0.040) were significantly associated with the length of time per attempt and incomplete evacuation separately for FC patients. CONCLUSION: These results may improve our understanding of the pathophysiological mechanisms underlying different types of constipation.
