ObjectiveThis paper aims to observe the syndrome improvement and negative antigen conversion rate of Qingxuan Daozhi formula in the treatment of influenza in children （heat accumulation in the lung and stomach syndrome）. MethodsThrough a multi-center randomized controlled methodology design，confirmed influenza cases were collected from October 2022 to April 2023 in the pediatrics department of eight hospitals，such as Dongfang Hospital of Beijing University of Chinese Medicine. A total of 180 children with influenza and heat accumulation in the lung and stomach syndrome conforming to the standard were recruited through the clinic. The sick children meeting the inclusion criteria were randomly divided into groups by a block-randomized method. The children in the experimental group were treated with Qingxuan Daozhi formula for five days，and those in the control group were treated with Oseltamivir Phosphate Granules for five days. The primary efficacy indicator was the negative conversion rate of influenza antigen detection. Secondary efficacy indicators were the Canadian acute respiratory illness and flu scale （CARIFS） and the incidence of complications，severe cases， and critical cases. Follow-up observation was conducted on the day of enrollment，48 hours after medication，72 hours after medication， and （6+1） d after medication. ResultsOne hundred and eighty participants were randomly assigned to the experimental group （90 cases） or the control group （90 cases）. All participants were followed up during the study. Comparison of influenza antigen detection results in the primary efficacy indicators showed that the average time of negative influenza antigen conversion in the experimental group was （5.29±1.25） d，and that in the control group was （5.40±1.68） d，without a statistically significant difference. After five days of intervention，52 cases in the experimental group and 51 cases in the control group converted to negative，without a statistically significant difference. CARIFS score results in the secondary efficacy indicators showed that during 72 hours after intervention，there were statistically significant differences between the experimental group and the control group in three dimensions， including headache，muscle soreness， and the need for extra care （P<0.05）. On the （6+1） days after the intervention，the differences in both the experimental group and the control group were statistically significant in 10 dimensions， including sore throat，bad sleep，uncomfortable feeling，poor spirit and fatigue，crying more than usual，the need for extra care，symptom，function，influence on parents，and total score （P<0.05）. The comparison results within the group in the dimensional scores of symptom， function， and influence on parents，as well as the CARIFS total score showed that with the delay of follow-up time，scores of both groups decreased significantly，with a statistically significant difference （P<0.01）. Inter-group comparison results showed that the mean score of the experimental group was higher than that of the control group at the time of enrollment. With the progress of intervention，the score of the experimental group was significantly decreased compared with that of the control group. At the end of follow-up，the mean score of the experimental group was lower than that of the control group，with no statistically significant difference. In terms of the incidence of complications，severe cases， and critical cases， there were no complications，severe cases， and critical cases in the two groups，without a statistically significant difference. ConclusionThe symptom improvement effect and negative antigen conversion rate of Qingxuan Daozhi formula in the treatment of influenza in children （heat accumulation in the lung and stomach syndrome） are not inferior to Oseltamivir Phosphate granules， and children's acceptance is better. It can be more widely used in clinical treatment of influenza in children （heat accumulation in the lung and stomach syndrome）.

Ureteropelvic junction obstruction (UPJO) is a condition characterized by the blockage of urine flow from the kidney to the ureter.With advancements in endoscopic technology, robotic-assisted laparoscopic dismembered pyeloplasty has become the dominant approach.However, approximately 10% of patients who undergo pyeloplasty still experience treatment failure, often due to long-segment proximal ureteral strictures (length greater than 2 cm).This increases the difficulty and risk of subsequent surgeries.In the past, ileal ureter replacement or kidney autotransplantation procedures were used as alternatives to shorten or replace the ureter.However, these procedures are associated with metabolic and vascular complications and are not always preferred.A pelvic flap, which utilizes the enlarged wall of the renal pelvis, is a good solution for bridging longer segments of a diseased ureter.This article reviews the specific applications of pelvic flap pyeloplasty in the existing literature and summarizes the technical improvements and research progress of renal pelvic flap pyeloplasty in our center to provide a reference for clinical application.

Placental transmogrification of the lung (PTL) is a very rare benign lung lesion. There are only about 40 cases reported in the literature. The imaging and histological features of PTL cases in the publication are various, most of which are cystic and a few of which are solid. Being extremely rare, the solid PTL is unknown to major pathologists and surgeons. We reported a case of solid PTL in the anterior mediastinum. The patient was a 52-year-old male with no history of smoking and without symptoms. During physical examination, chest CT revealed a circular low-density lesion with a maximum diameter of 2.9 cm beside the spine in the posterior basal segment of the left lower lobe of the lung. The wedge resection was performed by video-assisted thoracoscopy. Grossly, a round nodule was located underneath the visceral pleura. It was about 3.0 cm×3.0 cm×1.6 cm and the cut surface was grey-red, soft and spongy. Microscopically, the nodule was constituted of papillare, which resembled placental villi at low magnification. The axis of papillae was edema, in which some mild round cells with clear cytoplasm and CD10 positive staining aggregated and transitioned to immature adipocytes and amorphous pink materials deposited with a few of inflammatory cells infiltration. The surface of papillae was covered with disconti-nuous alveolar epithelium. Combined with the typical morphology and immunohistochemical characteristics of CD10 positive, the diagnosis was PTL. The patient was followed up for 1 year without recurrence and discomfort. So far, the pathogenesis of PTL is unclear. The major hypotheses include hamartoma, variant of emphysema and clonal hyperplasia of stromal cells. Based on the study of our case and publication, we speculate that the hyperplasia of stromal cells located in the alveolar septa might be the first step to form the solid PTL. With the progression of the disease, a typical unilateral cystic nodule develops as a result of secondary cystic degeneration due to the occlusive valve effect. Surgery is the only option for diagnosis and treatment of PTL. The clinician should make an individualized operation plan according to the clinical manifestations, location and scope of the lesion, and preserve the surrounding normal lung tissue as much as possible while completely removing the lesion. There is a favorable prognosis.

Objective: This study was to investigate the main characteristics and related factors of wideband absorbance (WBA) in children with normal hearing and to obtain age-specific reference range of WBA. Methods: 384 children between 0-12 years old (615 ears) who visited the Beijing Children's Hospital, Capital Medical University from October 2019 to February 2021 were enrolled, including 230 males (376 ears) and 154 females (239 ears), with totally 306 left ears and 309 right ears. Wideband tympanometry (WBT) was performed and normative WBA data were analyzed by SPSS 24.0 statistical software. Repeated measures and multivariate analysis of variance were applied to the data from 16 points at 1/3-octave frequencies (226, 324, 408, 500, 667, 841, 1 000, 1 297, 1 682, 2 000, 2 670, 3 364, 4 000, 5 339, 6 727 and 8 000 Hz) to evaluate the effects of frequency, age, external auditory canal pressures, gender and ear on WBA. Results: According to the WBT frequency-absorbance curve, the subjects were divided into seven groups: 1-month old group, 2-month old group, 3-month old group, 4-5 month old group, 6-24 month old group,>2-6 year old group and>6-12 year old group. The WBA of normal-hearing children underwent a series of developmental changes with age at both ambient pressure and tympanometric peak pressures. WBA results for 1-month group and 2-month old group exhibited a multipeaked pattern, with the peaks occurring around 2 000 and 4 897 Hz, and a notch around 3 886 Hz. WBA results for 3-month group and 4-5 month old group exhibited a single broad-peaked pattern, with the peak occurring between 2 000-4 757 Hz. The WBA of 1-month old group to 4-5 month old group decreased gradually at low frequency (226-408 Hz) and 6 727 Hz, and increased at middle to high frequency (2 670-4 000 Hz). The WBA of 6-24 month old group were significantly lower than that of 2-month old group to 4-5 month old group at all frequencies except 3 364 and 4 000 Hz. WBA results for 6-24 month old group,>2-6 year old group and>6-12 year old group exhibited a single-peaked pattern, and the peak frequency of WBA moved to the lower frequency successively. From 6-24 month old group to>6-12 year old group, the WBA gradually increased at low to middle frequencies (667-2 670 Hz) and 8 000 Hz, and decreased at middle to high frequencies (3 364-5 339 Hz). Among the 16 frequencies of all age groups, the difference between WBA under ambient pressure and tympanometric peak pressure were -0.09-0.06, and 43.75%-81.25% frequency points had statistically significant difference, which was mainly manifested in that WBA under ambient pressure were lower than that under tympanometric peak pressure at 226-1 682 Hz. There was no significant ear effect on all of the age groups. Similarly, there was no significant gender effect except for 3-month old group and 4-5 month old group. Conclusions: The WBA of normal-hearing children measured at ambient pressure and tympanometric peak pressure varied across the frequencies with age from 1 month to 12 years old, and different frequencies followed different change patterns (increase vs. decrease) in WBA. There was also significant external auditory canal pressures effect on all of the age groups. The establishment of age-specific reference range of WBA for 0-12 years old normal-hearing children in this study would be useful for clinical practice of determining normative data regarding WBT.

ObjectiveTo observe the effect of transcranial direct current stimulation (tDCS) combined with task-oriented rehabilitation training single pellet reaching and grasping (SPG) on the motor function of forelimb in rats with unilateral contusion of C₅ spinal cord. MethodsA total of 60 adult male Sprague-Dawley rats were randomly divided into sham operation group (sham group), spinal cord injury (SCI) group, tDCS group, SPG group, false group and tDCS+SPG group, with ten rats in each group. Only C₅ lamina was removed in the sham group, and the C₅ spinal cord contusion model was established by IH spinal cord impactor in the other five groups. The rats received tDCS in tDCS group, SPG in SPG group, tDCS without current in false group, tDCS combined with SPG in tDCS+SPG group, and no treatment in the SCI and the sham groups. The rats were evaluated with Rearing and Grooming tests, and motor-evoked potential (MEP). ResultsFour weeks after operation, compared with SCI group, the scores of Rearing and Grooming increased in tDCS group and tDCS+SPG group (P < 0.05), and they were more in the tDCS+SPG group than in tDCS group and SPG group (P < 0.05); the score of Grooming increased in SPG group (P < 0.05); while the amplitude of MEP increased in tDCS group, SPG group and tDCS+SPG group (P < 0.05), and the latency shortened in tDCS group and tDCS+SPG group (P < 0.05); and the amplitude increased more in tDCS+SPG group than in tDCS group and SPG group (P < 0.01). ConclusiontDCS could promote the recovery of motor function in rats with SCI, and the combination therapy of tDCS and task-oriented rehabilitation training is more effective.

OBJECTIVE: To explore the genotyping characteristics of human fecal Escherichia coli( E. coli) and the relationships between antibiotic resistance genes (ARGs) and multidrug resistance (MDR) of E. coli in Miyun District, Beijing, an area with high incidence of infectious diarrheal cases but no related data. METHODS: Over a period of 3 years, 94 E. coli strains were isolated from fecal samples collected from Miyun District Hospital, a surveillance hospital of the National Pathogen Identification Network. The antibiotic susceptibility of the isolates was determined by the broth microdilution method. ARGs, multilocus sequence typing (MLST), and polymorphism trees were analyzed using whole-genome sequencing data (WGS). RESULTS: This study revealed that 68.09% of the isolates had MDR, prevalent and distributed in different clades, with a relatively high rate and low pathogenicity. There was no difference in MDR between the diarrheal (49/70) and healthy groups (15/24). CONCLUSION We developed a random forest (RF) prediction model of TEM.1 + baeR + mphA + mphB + QnrS1 + AAC.3-IId to identify MDR status, highlighting its potential for early resistance identification. The causes of MDR are likely mobile units transmitting the ARGs. In the future, we will continue to strengthen the monitoring of ARGs and MDR, and increase the number of strains to further verify the accuracy of the MDR markers.

Objective: To understand the changes in pain and its effects in patients with the diagnosis of herpes zoster. Methods: A total of 3 487 patients diagnosed with herpes zoster (HZ) for the first time at the outpatient department of Miyun District Hospital from January 1, 2017, to December 31, 2019, were included in the study. The information of patients was registered and issued with a record card. Patients were required to record the time of pain and rash by themselves. Telephone follow-up was conducted at 21, 90, 180 and 365 days after the onset of rashes, including hospitalization, location of rash and pain, and the time of start and end. The impact of pain on life was evaluated by the Zoster Brief Pain Inventory (ZBPI). Results: The age of 2 999 HZ patients included in the analysis were (53±16) years old, including 1 377 (45.91%) males and 1 903 (63.45%) patients aged 50 years and older. After 21 days of rash, mild, moderate and severe pain accounted for 20.87% (626 cases), 37.98% (1 139 cases) and 33.81% (1 014 cases), respectively. Only 5.07% (152 cases) had no pain or discomfort, and 2.27% (68 cases) had no pain but discomfort. Most of the pain sites were consistent with the rash sites. The chest and back and waist and abdomen were the most common, accounting for 35.58% (1 067 cases) and 29.18% (875 cases), respectively, followed by the limbs and face and neck, accounting for 16.74% (502 cases) and 16.40% (492 cases), respectively. The M (Q₁, Q₃) of pain days in the HZ patients was 14 (8, 20) days, and the incidence of post-herpetic neuralgia (PHN) was 6.63% (171/2 580) (excluding 419 patients who refused to visit or lost to visit on 90 days after the onset of rash). The pain score of HZ patients within 21 days after the rash was (5.19±2.73) points, and the pain score of PHN patients was (7.61±2.13) points, which was significantly higher than that of non-PHN patients [(5.04±2.69) points] (P<0.001). Daily activities, emotions, walking ability, work, social interaction, sleep and recreation were affected for 21 days after the rash in HZ patients, ranging from 60.79% to 83.83%, with sleep being the most affected (83.83%). The impact scores of pain and life dimensions in PHN patients ranged from 4.59 to 7.61 points on the ZBPI scale, which were higher than those in non-PHN patients (2.49-5.04) (t values ranged from 8.86 to 11.67, all P values <0.001). Conclusion: The proportion of pain in HZ patients after the diagnosis is high, and the pain is more obvious in patients with PHN and HZ patients aged 50 and older, which has a greater impact on their daily lives.

OBJECTIVE: To study the trend of surgical type, surgical procedure and etiological distribution of upper urinary tract repair in recent 10 years. METHODS: The preoperative and perioperative variables and follow-up data of upper urinary tract reconstruction surgery in RECUTTER (Reconstruction of Urinary Tract: Technology, Epidemiology and Result) database from 2010 to 2021 were searched, collected and analyzed. The surgical type, surgical procedure, duration of hospitalization, time of operation, incidence of short-term complications, and proportion of the patients undergoing reoperations were compared between the two groups of 2010-2017 period and 2018-2021 period. RESULTS: A total of 1 072 patients were included in the RECUTTER database. Congenital factors and iatrogenic injuries were the main causes of upper urinary tract repair. Among them, 129 (12.0%) patients had open operation, 403 (37.6%) patients had laparoscopic surgery, 322 (30.0%) patients had robot-assisted laparoscopic surgery and 218 (20.3%) patients had endourological procedure. In the last decade, the total number of surgeries showed a noticeable increasing annual trend and the proportion of robot-assisted laparoscopic surgery in 2018-2021 was significantly higher than that in 2010-2017 (P < 0.001). The 1 072 patients included 124 (11.6%) cases of ileal ureter replacements, 440 (41.1%) cases of pyeloplasty, 229 (21.4%) cases of balloon dilation, 109 (10.2%) cases of ureteral reimplantation, 49 (4.6%) cases of boari flap-Psoas hitch surgery, 60 (5.6%) cases of uretero-ureteral anastomosis, 61 (5.7%) cases of lingual mucosal onlay graft ureteroplasty or appendiceal onlay flap ureteroplasty. Pyeloplasty and balloon dilatation had been the main types of surgery, while the proportion of lingual mucosal onlay graft ureteroplasty plus appendiceal onlay flap ureteroplasty had increased significantly in recent years (P < 0.05). In addition, the time of operation was significantly increased (P < 0.05) after 2018, which was considered to be related to the sharp increase in the proportion of robot-assisted laparoscopic surgery. We found that minimally invasive surgery (endourological procedure and robot-assisted laparoscopic surgery) as an independent risk factor (P=0.050, OR=0.472) could reduce the incidence of short-term post-operative complications. CONCLUSION We have justified the value of the RECUTTER database, created by the Institute of Urology, Peking University in data support for clinical research work, and provided valuable experience for the construction of other multi-center databases at home and abroad. In recent 10 years, we have observed that, in upper urinary tract reconstruction surgery, the surgery type tends to be minimally invasive and the surgery procedure tends to be complicated, suggesting the superiority of robot-assisted laparoscopic surgery.
