Objective:To summarized the clinical characteristics and surgical management of anterior cervical enterogenic in pediatric patients. Methods:Clinical data were retrospectively analyzed for 9 children with pathologically confirmed anterior cervical enterogenic cysts（including bronchogenic and esophagogenic subtypes） treated at the Children's Hospital of Shandong University（Jinan Children's Hospital） between January 1, 2020, and November 30, 2023. Results:Nine patients（6 males and 3 females） were involved in this study, aged 14 days to 10 years old. There were 4 cases on the left side, 4 on the right side, and 1 in the middle of the neck. All patients presented with neck masses. The patients were followed up from 3 months to 35 months after surgery and recovered well, with no recurrence or complications observed. Conclusion:①Anterior intestinal cysts in children are rare and easy to be misdiagnosed. ②Concurrent branchial cleft fistulas or associated anomalies may coexist, necessitating comprehensive evaluation. ③Preoperative diagnosis is not easy and mainly depends on pathological diagnosis. ④The treatment of anterior cervical enterogenic cysts in children is surgical resection of the lesion.

Objective:To investigate the association between gestational blood pressure and neurodevelopment in 2-year-old children.Methods:Based on the"Wuhan Healthy Baby Birth Cohort", 3 754 mother-infant pairs were enrolled in this study. Based on multiple blood pressure measurements during pregnancy, the mean, cumulative, and variability of blood pressure throughout the entire pregnancy and each trimester were calculated. Blood pressure variability was evaluated using standard deviation (SD), coefficient of variability (CV), and variability independent of mean (VIM). Follow-up testing of neurodevelopment in infants and young children at the age of two was conducted to obtain the Mental Development Index (MDI) and the Psychomotor Development Index (PDI). The multivariate linear regression and generalized estimation equation were used to analyze the association between gestational blood pressure data and neurodevelopmental index.Results:The age of 3 754 pregnant women was (29.1±3.6) years, with a pre-pregnancy BMI of (20.9±2.7) kg/m2 and a gestational age of (39.3±1.2) weeks. The birth weight of 3 754 children was (3 330.9±397.7) grams, and the birth length was (50.3±1.6) centimeters. The results of the multivariate linear regression analysis showed that after adjusting for relevant confounding factors, the mean blood pressure, cumulative blood pressure, standard deviation of blood pressure, coefficient of variation of blood pressure, independent blood pressure variability of systolic blood pressure, diastolic blood pressure, and pulse pressure throughout pregnancy were negatively associated with the MDI and PDI scores of 2-year-old children. The analysis results of the generalized estimation equation showed that after adjusting for relevant confounding factors, the average systolic blood pressure in the first, second, and third trimesters was negatively associated with MDI/PDI. The negative association between cumulative blood pressure and MDI/PDI was only found in the first trimester. The negative association between blood pressure variation during pregnancy and MDI/PDI was mainly concentrated in the second and third trimesters.Conclusion:There is a negative association between gestational blood pressure and the neurodevelopmental index of 2-year-old children.

Objective:To summarize and compare the characteristics of orthostatic hypotension (OH)　in　patients　with　Parkinson′s disease and multiple system atrophy (MSA).Methods:The active standing test data of 210 Parkinson′s disease patients (Parkinson′s disease group) and 85 MSA patients (MSA group) admitted to the Department of Neurology, Xuanwu Hospital, Capital Medical University from January 2021 to March 2022 were retrospectively analyzed. Demographic information, clinical data, Hoehn-Yahr staging, and Unified Parkinson′s Disease Rating Scale (UPDRS), Non-Motor Symptoms Questionnaire (NMSQ), Montreal Cognitive Assessment Scale and Mini-Mental State Examination scores were collected. The comparative analysis of OH was conducted according to the changes of heart rate and blood pressure during the active standing test.Results:Among the 85 patients with MSA, 52 were found with MSA parkinsonism variant (MSA-P) and 33 with MSA cerebellar variant (MSA-C). The 210 Parkinson′s disease patients were aged (61.5±11.0) years, with 116 males (55.2%). The 85　MSA　patients　were aged (60.1±6.8) years, with 44 males (51.8%). Compared with the Parkinson′s disease group, the Hoehn-Yahr staging [2.0(2.0, 3.0) vs 3.0(2.0, 3.0), Z=-5.278, P<0.001], NMSQ[ 25.0(11.0,46.5) vs 45.0(24.0,70.0), Z=-3.632, P<0.001] and UPDRS scores [50.0(32.0,68.0) vs 65.5(44.5,78.5), Z=-3.073, P=0.003] in the MSA group were higher. The incidence of OH in the MSA group was higher than that in the Parkinson′s disease group [63.5% (54/85) vs 25.7%(54/210), χ 2= 37.284, P<0.001], but there was no statistically significant difference between the MSA-P and MSA-C groups . Compared with the Parkinson′s disease group, the MSA group had a higher incidence of classical OH [54.1%(46/85) vs 12.9%(27/210), χ 2=55.316, P<0.001] and neurogenic OH [36.5%(31/85) vs 9.0%(19/210), χ 2=32.326, P<0.001],but there was no statistically significant difference in the incidence of initial OH and delayed OH between the two groups. The incidence of severe OH in the MSA group was also higher than that in the Parkinson′s disease group [57.6%(49/85) vs 16.7%(35/210), χ 2=49.894, P<0.001], but there was no statistically significant difference in the incidence of pre-clinical OH and mild OH between the two groups. Conclusions:The incidence, time change, severity and pathophysiological basis of OH in Parkinson′s disease and MSA patients are different. Different types of OH may help to distinguish MSA from Parkinson′s disease.

Objective To investigate the feasibility of retroperitoneoscopy in the treatment of adrenal masses in infants under 6 months old.Methods From January 2020 to November 2023,retroperitoneoscopic surgery was performed in 5 infants under 6 months old with adrenal tumors.Their age was from 1 month and 18 days to 4 months and 27 days,and their body weight was 5-8 kg.The lesion was found by prenatal ultrasonography in 1 case and by abdominal ultrasonography for other reasons after birth in 4 cases.Ultrasound and CT indicated a diameter of 1.7-5.5 cm for the adrenal masses.Results The operations of adrenalectomy and tumor resection were completed under retroperitoneoscopy.The operative time was 65-135 min(median,94 min).The intraoperative blood loss was less than 10 ml.The postoperative drainage tube retention time was 3-6 d(median,5 d).Pathological diagnosis showed 4 cases of adrenal neuroblastoma and 1 case of adrenal hyperplasia.Follow-ups for 1-36 months(median,3 months)with abdominal ultrasound and CT scanning showed no recurrence or metastasis.Conclusion Retroperitoneoscopy is relatively safe for the treatment of adrenal tumors in infants under 6 months old(tumors with acceptable boundaries).

Objective To summarize the clinical experience of thoracoscopic treatment of anterior mediastinal enterogenous cysts.Methods From July 2019 to July 2023,27 children diagnosed as having anterior mediastinal enterogenous cysts were treated with total thoracoscopic surgery through the lateral thoracic approach(three port method)in our department.The patients were placed in a healthy lateral position.The observation hole was located in the 5th intercostal space under the scapula,and the other 2 operating holes were established based on the location of the lesion and the endoscopic diamond-shaped method,both of which were 5 mm trocars.The CO2 pneumothorax was established at a pressure of 6 mm Hg.The visceral pleura of the cyst was opened with an electric hook,the cyst was fixed and pulled by intestinal forceps,and the cyst was completely removed by forceps and electric hook separation alternately.Results No conversion to thoracotomy was required.Complete resection was performed in 26 cases,and residual cyst wall existed in 1 case.Esophageal muscular layer was opened in 9 cases.During the operation,cysts obstructed the surgical field of view in 5 cases,which was not conducive to observation.The cyst puncture and fluid extraction were performed.The operation time was 45-120 min(median,70 min).The amount of blood loss was 3-10 ml(median,5 ml).Postoperative hospitalization lasted for 2-5 d(median,3d).The 27 cases were followed up for 1-43 months(median,22 months),and there was no recurrence.The compressed trachea in 2 cases was all recovered,with emphysema fully recovered.Conclusions Thoracoscopic treatment of anterior mediastinal enterogenous cysts in children is safe and feasible.When the surrounding structure of the lesion is complex,it can be combined with bronchoscopic or gastroscopic surgery if necessary.

Near-infrared (NIR)-light-triggered nanomedicine, including photodynamic therapy (PDT) and photothermal therapy (PTT), is growing an attractive approach for cancer therapy due to its high spatiotemporal controllability and minimal invasion, but the tumor eradication is limited by the intrinsic anti-stress response of tumor cells. Herein, we fabricate a tumor-microenvironment responsive CRISPR nanoplatform based on oxygen-deficient titania (TiO_2-x ) for mild NIR-phototherapy. In tumor microenvironment, the overexpressed hyaluronidase (HAase) and glutathione (GSH) can readily destroy hyaluronic acid (HA) and disulfide bond and releases the Cas9/sgRNA from TiO_2-x to target the stress alleviating regulators, i.e., nuclear factor E2-related factor 2 (NRF2) and heat shock protein 90α (HSP90α), thereby reducing the stress tolerance of tumor cells. Under subsequent NIR light illumination, the TiO_2-x demonstrates a higher anticancer effect both in vitro and in vivo. This strategy not only provides a promising modality to kills cancer cells in a minimal side-effects manner by interrupting anti-stress pathways but also proposes a general approach to achieve controllable gene editing in tumor region without unwanted genetic mutation in normal environments.

Objective:To explore the feasibility of using ligation clip-assisted modified " expansion and co-llapse method" to determine the intersegment plane in thoracoscopic resection of the external posterior basal segment (S 9+ 10) in children with congenital pulmonary airway malformation (CPAM). Methods:Retrospective study.The clinical data of 12 CPAM children who underwent thoracoscopic S 9+ 10 resection in Children′s Hospital Affiliated to Shandong University from July 2019 to May 2021 were collected and analyzed.There were 7 males and 5 females.The age at operation ranged from 3.50 to 11.50 months.The body weight of patients ranged from 6.5 to 11.5 kg.In all the patients, the ligation clip-assisted modified " expansion and collapse method" was applied during the operation to determine the intersegment plane (S 9+ 10 was in the expansion state and the remaining lungs were in the collapse state) before thoracoscopic S 9+ 10 resection.After S 9+ 10 resection, the surgical treatment and postoperative recovery were summarized and analyzed. Results:All the operations were completed under thoracoscopy, and there was no conversion to thoracotomy.In 11 patients, the intersegment plane was accurately determined by the ligation clips-assisted improved " expansion and collapse method" , and the S 9+ 10 segment was successfully resected.Of these 11 cases, 8 cases had right S 9+ 10 resection and 3 cases had left S 9+ 10 resection.In the process of using the ligation clip-assisted improved " expansion and collapse method" to determine the intersegment plane, the operator needed to clamp the ligation clip after the anesthesiologist expanded the lung completely.Because the operation was not stable enough, the ligation clip fell off and did not clamp S 9+ 10, resulting in operation failure.The operation was changed to the traditional " expansion and collapse method" . Besides, the basal segment bronchus was cut off by mistake, so the right basal segment had to be resected.The operation time ranged from 85 to 205 min, with a median of 149 min.Intraoperative bleeding ranged from 5 to 15 mL, with a median of 10 mL.The indwelling time of drainage tubes ranged from 2 to 4 days, with a median of 3 days.The postoperative hospital stay ranged from 5 to 8 days, with a median of 6 days.Postoperative pathological examination results suggested 4 cases of type 1, 6 cases of type 2 and 2 cases of type 3.There were 2 cases of simple subcutaneous emphysema without postoperative complications such as bleeding, bronchopleural fistula and atelectasis.The follow-up time ranged from 6 to 28 months, with a median of 15 months.The chest CT of all children showed no residual lesions and no residual cavities in the involved hemithorax. Conclusions:Ligation clip-assisted improved " expansion and collapse method" for determining the intersegment plane is suitable for CPAM children with a narrow thoracic space, and the operation is simple and effective.It is relatively safe and feasible to use this method in S 9+ 10 resection.
