Objective: Retrospective analysis of the efficacy and influencing factors of bladder preservation integrated therapy for unresectable invasive bladder cancer confined to the pelvis was done, also including the bladder function preservation and adverse effects analysis. Methods: Sixty-nine patients with unresectable locally invasive bladder cancer who received radiotherapy-based combination therapy from March 1999 to December 2021 at our hospital were selected. Among them, 42 patients received concurrent chemoradiotherapy, 32 underwent neoadjuvant chemotherapyand 43 with transurethral resection of bladder tumors (TURBT) prior to radiotherapy. The late adverse effect of radiotherapy, preservation of bladder function, replase and metastasis and survival were followed-up. Cox proportional hazards models were applied for the multifactorial analysis. Results: The median age was 69 years. There were 63 cases (91.3%) of uroepithelial carcinoma, 64 of stage Ⅲ and 4 of stage Ⅳ. The median duration of follow-up was 76 months. There were 7 grade 2 late genito urinary toxicities, 2 grade 2 gastrointestinal toxicities, no grade 3 or higher adverse events occurred. All patients maintained normal bladder function, except for 8 cases who lost bladder function due to uncontrolled tumor in the bladder. Seventeen cases recurred locally. There were 11 cases in the concurrent chemoradiotherapy group with a local recurrence rate of 26.2% (11/42) and 6 cases in the non-concurrent chemoradiotherapy group with a local recurrence rate of 22.2% (6/27), and the difference in local recurrence rate between the two groups was not statistically significant (P=0.709). There were 23 cases of distant metastasis (including 2 cases of local recurrence with distant metastasis), including 10 cases in the concurrent chemoradiotherapy group with a distant metastasis rate of 23.8% (10/42) and 13 cases in the non-concurrent chemoradiotherapy group with a distant metastasis rate of 48.1% (13/27), and the distant metastasis rate in the non-concurrent chemoradiotherapy group was higher than that in the concurrent chemoradiotherapy group (P=0.036). The median 5-year overall survival (OS) time was 59 months and the OS rate was 47.8%. The 5-year progression-free survival (PFS) time was 20 months and the PFS rate was 34.4%. The 5-year OS rates of concurrent and non-concurrent chemoradiotherapy group were 62.9% and 27.6% (P<0.001), and 5-year PFS rates were 45.4% and 20.0%, respectively (P=0.022). The 5-year OS rates of with or without neoadjuvant chemotherapy were 78.4% and 30.1% (P=0.002), and the 5-year PFS rates were 49.1% and 25.1% (P=0.087), respectively. The 5-year OS rates with or without TURBT before radiotherapy were 45.5% and 51.9% (P=0.233) and the 5-year PFS rates were 30.8% and 39.9% (P=0.198), respectively. Multivariate Cox regression analysis results showed that the clinical stage (HR=0.422, 95% CI: 0.205-0.869) was independent prognostic factor for PFS of invasive bladder cancer. The multivariate analysis showed that clinical stages (HR=0.278, 95% CI: 0.114-0.678), concurrent chemoradiotherapy (HR=0.391, 95% CI: 0.165-0.930), neoadjuvant chemotherapy (HR=0.188, 95% CI: 0.058-0.611), and recurrences (HR=10.855, 95% CI: 3.655-32.638) were independent prognostic factors for OS of invasive bladder cancer. Conclusion: Unresectable localized invasive bladder cancer can achieve satisfactory long-term outcomes with bladder-preserving combination therapy based on radiotherapy, most patients can retain normal bladder function with acceptable late adverse effects and improved survival particularly evident in patients with early, concurrent chemoradiotherapy and neoadjuvant chemotherapy.

Objective: To investigate the related factors and treatments of delayed cerebrospinal fluid rhinorrhea (CFR) after invasive pituitary adenoma (IPA) surgery. Methods: One hundred and forty-two patients with IPA treated in Tianjin Huanhu Hospital from January 2014 to January 2019 were analyzed retrospectively, including 62 males and 80 females, aging from 38 to 67 years. The clinical data of patients before and after operation were collected. All patients with postoperative CFR underwent endoscopic CFR repair. During the operation, residual or recurrent pituitary adenomas were resected, the dura around the leak was enlarged and the necrotic tissue was removed. For those who still had fluid leakage after repair, the necrotic tissue was cleaned up, the leakage was filled and reinforced under endoscopy. Endoscopic rhinorrhea repair was performed if necessary. The cerebrospinal fluid leak was repaired with multi-layer materials. The related risk factors of delayed CFR after operation were analyzed. SPSS 19.0 software was used for statistical analysis. Results: Among the 142 patients in this group, 64 cases underwent total tumor resection and 78 cases underwent non-total tumor resection. They were followed up for 6 to 72 months. Thirty-one cases had delayed CFR, with an incidence of 21.83%, and occurred between 1 and 5 years postoperatively, with an average of 2.4 years. All 31 patients with delayed CFR underwent endoscopic CFR repair. The nasal endoscopy was rechecked at 2 weeks, 1 month, 3 months and 6 months after operation. Twenty-eight patients were repaired successfully after 1 operation, while 2 patients after 2 operations and 1 patient after 3 operations. These patients were followed up for 6 to 60 months, and no CFR occurred again. Univariate analysis showed that the degree of tumor resection, recurrence, size, texture, postoperative radiotherapy and operator experience were the risk factors of delayed CFR (all P<0.05). Multivariate analysis showed that the degree of tumor resection and recurrence were the highest independent risk factors for postoperative CFR, and tumor size, texture, postoperative radiotherapy and operator experience were the independent risk factors in this study. Conclusions: Delayed CFR after IPA is related to the degree of tumor resection, recurrence, size, texture, postoperative radiotherapy and the operator experience. It is necessary to completely remove the tumor under endoscope, to expand resection of the dura and necrotic tissue around the leak, to repair the defect with multi-layer materials, to follow-up closely and to repair timely after operation.

ObjectiveTo evaluate the clinical efficacy of sequential syndrome differentiation of Yiqi Huayu Qingre prescription (YHQ) in the treatment of refractory nephrotic syndrome in children. MethodA total of 112 children with refractory nephrotic syndrome were randomly divided into an observation group (57 cases) and a control group(55 cases). The children in the control group were treated with prednisone tablets combined with tacrolimus,and those in the observation group were treated with YHQ by sequential syndrome differentiation on the basis of the control group. The total effective rates of the two groups after treatment were observed. The 24-hour urinary total protein(24 h UTP),plasma albumin(ALB),cholesterol(CHO),triglycerides(TG), and traditional Chinese medicine quality of life scale scores before treatment and after four weeks,eight weeks,16 weeks,24 weeks,32 weeks,40 weeks,and 52 weeks in the two groups were recorded. The total course of treatment and the total accumulation of hormones were compared among the children with reduced or no hormone treatment till 52 weeks during treatment. ResultThe total effective rate in the observation group was higher (Z=-2.052,P<0.05). The observation group had lower 24 h UTP and higher ALB at each follow-up time point than the control group(P<0.05,P<0.01). At four weeks,eight weeks,and 16 weeks of treatment,there was no statistically significant difference in CHO between the observation group and the control group,and the observation group was lower than the control group in CHO at the rest of the time points (P<0.05,P<0.01). For TG, the observation group was not significantly different from the control group at four weeks,eight weeks,16 weeks,and 40 weeks of treatment,but lower at 24,32,and 52 weeks (P<0.05,P<0.01). The total treatment course of hormones in the observation group was shorter(P<0.01), with less total accumulation(P<0.01). At different follow-up time points,the total score of traditional Chinese medicine quality of life scale in the observation group was superior to that in the control group(P<0.05,P<0.01),and the scores of the observation group in the four dimensions (physiological function,independent factor,social factor,and psychological factor) after treatment were higher than those in the control group(P<0.05,P<0.01). ConclusionYHQ under sequential syndrome differentiation has a definite clinical effect in treating children with refractory nephrotic syndrome. It has advantages in shortening the total course of hormone treatment and reducing the total accumulation of hormones,and can improve the quality of life of children with refractory nephrotic syndrome.

Objective: To analyze the clinical characteristics of children with Burkitt lymphoma (BL) and to summarize the mid-term efficacy of China Net Childhood Lymphoma-mature B-cell lymphoma 2017 (CNCL-B-NHL-2017) regimen. Methods: Clinical features of 436 BL patients who were ≤18 years old and treated with the CNCL-B-NHL-2017 regimen from May 2017 to April 2021 were analyzed retrospectively. Clinical characteristics of patients at disease onset were analyzed and the therapeutic effects of patients with different clinical stages and risk groups were compared. Survival analysis was performed by Kaplan-Meier method, and Cox regression was used to identify the prognostic factors. Results: Among 436 patients, there were 368 (84.4%) males and 68 (15.6%) females, the age of disease onset was 6.0 (4.0, 9.0) years old. According to the St. Jude staging system, there were 4 patients (0.9%) with stage Ⅰ, 30 patients (6.9%) with stage Ⅱ, 217 patients (49.8%) with stage Ⅲ, and 185 patients (42.4%) with stage Ⅳ. All patients were stratified into following risk groups: group A (n=1, 0.2%), group B1 (n=46, 10.6%), group B2 (n=19, 4.4%), group C1 (n=285, 65.4%), group C2 (n=85, 19.5%). Sixty-three patients (14.4%) were treated with chemotherapy only and 373 patients (85.6%) were treated with chemotherapy combined with rituximab. Twenty-one patients (4.8%) suffered from progressive disease, 3 patients (0.7%) relapsed, and 13 patients (3.0%) died of treatment-related complications. The follow-up time of all patients was 24.0 (13.0, 35.0) months, the 2-year event free survival (EFS) rate of all patients was (90.9±1.4) %. The 2-year EFS rates of group A, B1, B2, C1 and C2 were 100.0%, 100.0%, (94.7±5.1) %, (90.7±1.7) % and (85.9±4.0) %, respectively. The 2-year EFS rates was higher in group A, B1, and B2 than those in group C1 (χ2=4.16, P=0.041) and group C2 (χ2=7.21, P=0.007). The 2-year EFS rates of the patients treated with chemotherapy alone and those treated with chemotherapy combined with rituximab were (79.3±5.1)% and (92.9±1.4)% (χ2=14.23, P<0.001) respectively. Multivariate analysis showed that stage Ⅳ (including leukemia stage), serum lactate dehydrogenase (LDH)>4-fold normal value, and with residual tumor in the mid-term evaluation were risk factors for poor prognosis (HR=1.38,1.23,8.52,95%CI 1.05-1.82,1.05-1.43,3.96-18.30). Conclusions: The CNCL-B-NHL-2017 regimen show significant effect in the treatment of pediatric BL. The combination of rituximab improve the efficacy further.

BACKGROUND:
Delivery room resuscitation assists preterm infants, especially extremely preterm infants (EPI) and extremely low birth weight infants (ELBWI), in breathing support, while it potentially exerts a negative impact on the lungs and outcomes of preterm infants. This study aimed to assess delivery room resuscitation and discharge outcomes of EPI and ELBWI in China.
METHODS:
The clinical data of EPI (gestational age [GA] <28 weeks) and ELBWI (birth weight [BW] <1000 g), admitted within 72 h of birth in 33 neonatal intensive care units from five provinces and cities in North China between 2017 and 2018, were analyzed. The primary outcomes were delivery room resuscitation and risk factors for delivery room intubation (DRI). The secondary outcomes were survival rates, incidence of bronchopulmonary dysplasia (BPD), and risk factors for BPD.
RESULTS:
A cohort of 952 preterm infants were enrolled. The incidence of DRI, chest compressions, and administration of epinephrine was 55.9% (532/952), 12.5% (119/952), and 7.0% (67/952), respectively. Multivariate analysis revealed that the risk factors for DRI were GA <28 weeks (odds ratio [OR], 3.147; 95% confidence interval [CI], 2.082-4.755), BW <1000 g (OR, 2.240; 95% CI, 1.606-3.125), and antepartum infection (OR, 1.429; 95% CI, 1.044-1.956). The survival rate was 65.9% (627/952) and was dependent on GA. The rate of BPD was 29.3% (181/627). Multivariate analysis showed that the risk factors for BPD were male (OR, 1.603; 95% CI, 1.061-2.424), DRI (OR, 2.094; 95% CI, 1.328-3.303), respiratory distress syndrome exposed to ≥2 doses of pulmonary surfactants (PS; OR, 2.700; 95% CI, 1.679-4.343), and mechanical ventilation ≥7 days (OR, 4.358; 95% CI, 2.777-6.837). However, a larger BW (OR, 0.998; 95% CI, 0.996-0.999), antenatal steroid (OR, 0.577; 95% CI, 0.379-0.880), and PS use in the delivery room (OR, 0.273; 95% CI, 0.160-0.467) were preventive factors for BPD (all P < 0.05).
CONCLUSION
Improving delivery room resuscitation and management of respiratory complications are imperative during early management of the health of EPI and ELBWI.

Objective: To indicate the clinical features of endoscopic transnasal resection of epidural cholesteatoma at paracentral skull base and to analyze its efficacy. Methods: The total excision rate, postoperative complications and postoperative curative effect of 7 patients (4 males and 3 females, aging from 32 to 63 years old) who underwent middle skull base surgery for epidural cholesteatoma resection under transnasal endoscope at Tianjin Huanhu Hospital between August 2017 and August 2020 were retrospectively reviewed. All patients were followed up for 6 to 36 months. The postoperative MRI, clinical symptoms and recurrence were reviewed. Descriptive statistical methods were used for analysis. Results: Among the 7 patients, there were total resection (complete resection of cyst contents and capsule) in 4 patients, near-total resection (complete resection of cyst contents, incomplete resection of cyst capsule) in 1 patient, and subtotal resection (incomplete resection of cyst contents and capsule) in 2 patients. The clinical symptoms of all patients were improved postoperatively with 1 patient who had no clinical symptoms. One case had postoperative cerebrospinal fluid rhinorrhea, which was cured after lumbar drainage and nasal iodoform gauge packing. Up to now, 7 patients (including patients with partial resection) had no recurrence. Conclusion: Endoscopic transnasal approaches may be effectively used for resection of epidural cholesteatoma in the paracentral skull base in carefully selected cases.

Objective:To explore the significance of empathy and executive function indexes in the diagnosis and classification of autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD).Methods:According to DSM-Ⅴ diagnostic criteria, 33 children with ASD, 30 children with ADHD and 39 typical development (TD) children and adolescents were enrolled as the research subjects.The empathy and executive function characteristics were compared and analyzed in the subjects.Based on empathy and executive function indicators, the three groups of subjects were diagnosed and classified by machine learning method.Results:The total score of Griffith empathy measure parent ratings(GEM-PR)(ASD: (0.67±0.64), ADHD: (1.00±0.79), TD: (0.98±0.73)) and each factor score ( F=3.595-10.363, all P<0.05) and the total score of behavior rating inventory of executive function(BRIEF)(ASD: (62.79±7.45), ADHD: (59.47±8.77), TD: (49.08±7.91)) and each factor score of the three groups were different ( F=6.557-33.205, all P<0.01). Among them, the scores of empathy and executive function in ASD and ADHD groups were generally higher than those in TD children (all P<0.05). When combined with BRIEF scale and GEM scale, the classification accuracy of the three groups reached 62.75%. Conclusion:Both ASD and ADHD children have damages in empathy and executive function.Combining empathy and executive function indexes are more helpful for diagnosis and classification than single index.
