Gorham-Stout disease(GSD) is a rare osteolytic disorder characterized by spontaneous and progressive osteolysis, along with abnormal angiogenesis and lymphangiogenesis, with no new bone formation. We present a case of a 15-year-old female admitted due to " recurrent right leg pain for 5 years, 11 months after undergoing right femoral fracture surgery". Through comprehensive integration of the patient's clinical phenotype, laboratory tests, imaging findings, pathological examinations, and molecular biological test results, GSD was considered highly likely. A multidisciplinary treatment approach was conducted, including a combination of zoledronic acid and sirolimus to inhibit osteolysis, along with rehabilitation training and orthopedic intervention, providing a personalized and comprehensive treatment strategy.

Objective To observe the value of CT angiography(CTA)for classifying type of peripheral arteriovenous fistula(AVF)in children.Methods Totally 22 children with peripheral AVF were retrospectively enrolled,the type of AVF was classified with preoperative CTA,and therapeutic planning was developed.Taken digital subtraction angiography(DSA)findings during interventional therapy as gold standards,the efficacy of CTA for classifying type of AVF was analyzed.Results Among 22 cases,DSA detected 3 cases of type Ⅰ,13 cases of type Ⅱa and 6 cases of typeⅡb peripheral AVF,while 3 cases of type Ⅰ,14 cases of type Ⅱa and 5 cases of type Ⅱb peripheral AVF were classified based on CTA.CTA misdiagnosed 1 case of type Ⅱa as type Ⅱb,and 2 cases of type Ⅱb as type Ⅱa peripheral AVF,its accuracy of CTA for classifying type Ⅰ,Ⅱa and Ⅱb peripheral AVF was 100%(3/3),92.31%(12/13)and 66.67%(4/6),respectively.Among 22 cases,13 cases underwent interventional closure,2 cases underwent interventional therapy combined with surgery,while 3 cases did not receive relevant treatment due to drainage vein occlusion.One month after treatments,the symptoms of 19 cases who underwent treatment improved significantly,and no signs of AVF was found with re-examination of ultrasound nor CTA.Conclusion CTA was helpful to classifying type of peripheral AV in children,which could provide references for interventional therapy.

OBJECTIVE To provide reference for improving the rational use of antimicrobial drugs in primary township medical institutions. METHODS Based on the county prescription pre-review center， a team led by anti-infective clinical pharmacists constructed the management mode for the use of antimicrobial drugs in county-level medical communities with clinical pharmacists as the main team by finding out the main problems in the use of antimicrobial drugs in primary township medical institutions， providing feedback on the problems， organizing relevant training for the problems， improving the customization rules of the prescription pre-review software， implementing the automatic interception and pharmacist online prescription review and other measures. Data on the use of antimicrobial drugs were collected and compared in the 15 primary township medical institutions between January-June in 2022 （before the implementation of the mode） and January-June in 2023 （after the implementation of the mode）. RESULTS Compared with before the implementation of the mode， the utilization rate of antimicrobial drugs in outpatients of primary township medical institutions decreased from 24.97% before the implementation of the mode to 19.39% after the implementation of the mode； the utilization rate of antimicrobial injection in outpatients decreased from 66.10% to 46.80%； the utilization rate of intravenous drip of antimicrobial drugs in outpatients decreased from 52.33% to 40.35%； the rates of combined use of antimicrobial drugs in outpatients decreased from 12.70% to 8.19%； the reasonable rate of antimicrobial prescribing in outpatients increased from 55.28% to 73.93%. After the implementation of the mode， the proportion of antimicrobial prescriptions for each diagnosis was basically the same as before； the defined daily dose system （DDDs） and proportion of a few antimicrobial drugs changed compared with before according to the anatomical therapeutic chemical classification of drugs， among which DDDs of lincomycin， gentamicin and other drugs declined significantly； DDDs of antimicrobial drugs for each classification was basically the same as before according to AWaRe classification. CONCLUSIONS The management mode of the use of antimicrobial drugs led by anti-infective clinical pharmacists is constructed in the prescription pre-reviewing center of county-level medical communities， which can effectively improve the rational use of antimicrobial drugs in the primary township medical institutions.

Temporomandibular joint (TMJ) diseases are common clinical conditions. The number of patients with TMJ diseases is large, and the etiology, epidemiology, disease spectrum, and treatment of the disease remain controversial and unknown. To understand and master the current situation of the occurrence, development and prevention of TMJ diseases, as well as to identify the patterns in etiology, incidence, drug sensitivity, and prognosis is crucial for alleviating patients′suffering.This will facilitate in-depth medical research, effective disease prevention measures, and the formulation of corresponding health policies. Cohort construction and research has an irreplaceable role in precise disease prevention and significant improvement in diagnosis and treatment levels. Large-scale cohort studies are needed to explore the relationship between potential risk factors and outcomes of TMJ diseases, and to observe disease prognoses through long-term follw-ups. The consensus aims to establish a standard conceptual frame work for a cohort study on patients with TMJ disease while providing ideas for cohort data standards to this condition. TMJ disease cohort data consists of both common data standards applicable to all specific disease cohorts as well as disease-specific data standards. Common data were available for each specific disease cohort. By integrating different cohort research resources, standard problems or study variables can be unified. Long-term follow-up can be performed using consistent definitions and criteria across different projects for better core data collection. It is hoped that this consensus will be facilitate the development cohort studies of TMJ diseases.

A group of compounds structurally related to tetrahydrocannabinol or capable of binding to cannabinoid receptors are collectively referred to as cannabinoids. Cannabinoids can be divided into plant derived cannabinoids， synthetic cannabinoids， and endogenous cannabinoids. Δ-9-THC is the only psychoactive compound in plant cannabinoids. Cannabis with Δ-9-THC>0.3% is internationally listed as a prohibited drug， while cannabis with Δ-9-THC<0.3% is industrial cannabis. Due to its low addiction and high commercial value， it is allowed to be added to food in many countries. More and more industrial cannabis foods become popular， and the detection/analysis of cannabinoid compounds in cannabis foods is particularly important； In addition to industrial cannabis， which is widely used in food， there are also various new drugs， synthetic cannabinoids， disguised as conventional food， which can cause the social problems and increase the food safety risks. This article will elaborate on the regulatory status of cannabinoid compounds in food， In order to promote the safety supervision of the domestic cannabis food.

Objective: To investigate the impact of obstructive sleep apnea syndrome (OSAS) on pregnancy outcomes, especially the relationship between OSAS and hypertensive disorders in pregnancy (HDP). Methods: A total of 228 pregnant women with high risk of OSAS who underwent sleep monitoring during pregnancy in Peking University People's Hospital from January 2021 to April 2022 were collected by reviewing their medical records for retrospective analysis. According to the diagnosis of OSAS, the pregnant women were divided into OSAS group (105 cases) and non-OSAS group (123 cases). The non-parametric Mann-Whitney U test, χ² test or Fisher's exact test were used to compare the general data and maternal and fetal outcomes between the two groups, and the occurrence of each type of HDP was further compared. Results: (1) Compared with the non-OSAS group, the median pre-pregnancy body mass index (23.6 vs 27.6 kg/m²) and the proportion of snoring [28.9% (33/114) vs 59.2% (61/103)] in the OSAS group were higher, and the differences were both statistically significant (both P<0.001). (2) The incidence of HDP [67.6% (71/105) vs 39.0% (48/123)] and gestational diabetes mellitus [GDM; 40.0% (42/105) vs 26.8% (33/123)] of pregnant women in the OSAS group were higher than those in the non-OSAS group, and the median delivery week was shorter than that in the non-OSAS group (38.4 vs 39.0 weeks). The differences were all statistically significant (all P<0.05). Between-group differences for the delivery way, postpartum hemorrhage, the rate of intensive care unit admission, preterm birth, small for gestational age infants, neonatal asphyxia, the rate of neonatal intensive care unit admission, newborn birth weight and the proportion of umbilical artery blood pH<7.00 were not statistically significant (all P>0.05). (3) Compared with the non-OSAS group, the incidence of chronic hypertension [11.4% (14/123) vs 22.9% (24/105)] and chronic hypertension with superimposed pre-eclampsia [11.4% (14/123) vs 30.5% (32/105)] were higher in the OSAS group, and the differences were both statistically significant (both P<0.01). Conclusion: OSAS is related to HDP (especially chronic hypertension and chronic hypertension with superimposed pre-eclampsia) and GDM, which could provide a practical basis for the screening, diagnosis and treatment of OSAS in pregnant women at high risk.

OBJECTIVES: To investigate the clinical treatment outcomes and the changes of the outcomes over time in extremely preterm twins in Guangdong Province, China. METHODS: A retrospective analysis was performed for 269 pairs of extremely preterm twins with a gestational age of <28 weeks who were admitted to the department of neonatology in 26 grade A tertiary hospitals in Guangdong Province from January 2008 to December 2017. According to the admission time, they were divided into two groups: 2008-2012 and 2013-2017. Besides, each pair of twins was divided into the heavier infant and the lighter infant subgroups according to birth weight. The perinatal data of mothers and hospitalization data of neonates were collected. The survival rate of twins and the incidence rate of complications were compared between the 2008-2012 and 2013-2017 groups. RESULTS: Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of severe asphyxia and smaller head circumference at birth (P<0.05). The mortality rates of both of the twins, the heavier infant of the twins, and the lighter infant of the twins were lower in the 2013-2017 group compared with the 2008-2012 group (P<0.05). Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of pulmonary hemorrhage, patent ductus arteriosus (PDA), periventricular-intraventricular hemorrhage (P-IVH), and neonatal respiratory distress syndrome (NRDS) and a higher incidence rate of bronchopulmonary dysplasia (P<0.05). CONCLUSIONS There is a significant increase in the survival rate over time in extremely preterm twins with a gestational age of <28 weeks in the 26 grade A tertiary hospitals in Guangdong Province. The incidences of severe asphyxia, pulmonary hemorrhage, PDA, P-IVH, and NRDS decrease in both the heavier and lighter infants of the twins, but the incidence of bronchopulmonary dysplasia increases. With the improvement of diagnosis and treatment, the multidisciplinary collaboration between different fields of fetal medicine including prenatal diagnosis, obstetrics, and neonatology is needed in the future to jointly develop management strategies for twin pregnancy.

OBJECTIVES: To investigate the influencing factors for the quality of bowel preparation before colonoscopy in children and the association of the interval from the last administration of laxative to the start of colonoscopy (shortly referred to as waiting time) with the quality of bowel preparation. METHODS: A retrospective analysis was performed for the children who were admitted to the Department of Gastroenterology, Children's Hospital of Nanjing Medical University, from January to November 2020, and received bowel preparation with polyethylene glycol electrolyte powder combined with diet control before colonoscopy. According to the score of Boston bowel preparation scale, they were divided into two groups: adequate bowel preparation group (n=337) and inadequate bowel preparation group (n=30). Related data were collected from the children in both groups, including general information, possible influencing factors for the quality of bowel preparation, adverse reactions associated with bowel preparation, duration of colonoscopy, and postoperative diagnosis. Univariate and multivariate analyses were used to explore the influencing factors for the quality of bowel preparation. RESULTS: The univariate analysis showed that age, body weight, and waiting time were associated with inadequate bowel preparation (P<0.05). The multivariate analysis showed that older age (OR=2.155, 95%CI: 1.087-4.273, P=0.028) and longer waiting time (OR=1.559, 95% CI: 1.191-2.041, P=0.001) were independent risk factors for inadequate bowel preparation. The receiver operating characteristic (ROC) curve analysis showed that the cut-off value of waiting time was 5.5 hours in determining whether bowel preparation was adequate or not, with a sensitivity of 90.0%, a specificity of 50.7%, and an area under the ROC curve of 0.708. After grouping based on waiting time, it was found that the incidence rate of inadequate bowel preparation in the ≥5.5 hours group was significantly higher than that in the <5.5 hours group [14.0% (27/193) vs 1.7% (3/174), P<0.001]. CONCLUSIONS For children who use polyethylene glycol electrolyte powder combined with diet control for bowel preparation, older age is an independent risk factor for inadequate bowel preparation before colonoscopy, which may be associated with an insufficient dose of polyethylene glycol in older children. Longer waiting time is also an independent risk factor for inadequate bowel preparation, and it is recommended that the waiting time should not exceed 5.5 hours.
