OBJECTIVE: To summarize the clinical and genetic characteristics of a child with 46,XX Ovotesticular disorder of sex development (46,XX OTDSD) due to copy number variation of SOX3 gene. METHODS: A 46,XX male patient presented at the Capital Center for Children's Health, Capital Medical University in November 2024 was selected as the study subject. Clinical data of the child was collected. Peripheral blood samples were taken from the child and his parents and subjected to trio whole-genome sequencing. Skewed X-chromosome inactivation was tested in the child and his mother. A literature review was carried out on 46,XX males associated with mutations of the SOX3 gene. This study was approved by the Medical Ethics Committee of the Hospital (Ethics No.: SHERLL2025056). RESULTS: The 10-year-old boy presented with hypospadias and cryptorchidism at birth. Chromosome analysis at one year and a half revealed a 46,XX karyotype. Gonadal biopsy showed testicular tissue, while ultrasound at the age of 10 detected ovotesticular tissue. Whole-genome sequencing identified a 660 kb duplication in the Xq27.1 region, which was derived from his mother. X-chromosome inactivation testing showed random inactivation in the child and mild non-random inactivation in the mother. Literature review has found 11 publications involving 15 patients (including our case), among whom 14 had a male social gender. They had primarily presented with hypospadias at birth but had no significant endocrine abnormalities. Most patients had experienced testicular failure after puberty. SOX3 related 46,XX males are mainly caused by de novo duplications, although a few maternal carriers had been discovered. CONCLUSION Duplication of the SOX3 gene probably underlay the pathogenesis is this 46,XX male. Individuals with 46,XX SRY negative male phenotypes should be routinely screened for SOX3 gene variants. Structural variations of the SOX3 gene can lead to complete or partial sex reversal in 46,XX individuals with minimal impact on intellectual and motor development, as well as other endocrine hormones.

OBJECTIVE To provide a reference for anticoagulant therapy and vaginal bleeding management during medical abortion in patients with missed abortion after aortic mechanical valve replacement surgery. METHODS Clinical pharmacists conducted pharmaceutical monitoring on a patient with missed abortion after aortic mechanical valve replacement surgery， and analyzed the correlation between warfarin use and abortion. In response to gingival bleeding and an increase in the international normalized ratio （INR） after taking mifepristone， clinical pharmacists recommended discontinuing warfarin based on bleeding risk and INR changes； for the selection of sex hormones after missed abortion， clinical pharmacists suggested that estradiol gel combined with progesterone should be used in sequential treatment， supplemented by Xian yimucao capsules， to accelerate the elimination of residual tissue and congestion in uterine cavity. RESULTS The physician followed the advice of the clinical pharmacist and did not prolong the patient’s hospital stay due to excessive vaginal bleeding during treatment. Warfarin treatment was restarted on the day of discharge， and INR remained stable within the target anticoagulation range after discharge without any adverse events such as thromboembolism. CONCLUSIONS In patients with missed abortion after aortic valve replacement surgery， mifepristone may enhance the anticoagulant effect of warfarin and increase the risk of bleeding during medical abortion. It is recommended to discontinue warfarin before medication. Clinical pharmacists play a crucial role in the development of anticoagulation plans， identification of drug-drug interactions， assessment of bleeding risks， and selection of postoperative sex hormones. Through full pharmaceutical monitoring， they ensure the safety of patients’ medication.

Objective:To evaluate the effect of ciprofol on intraoperative hypotension in patients undergoing bronchoscopy procedures.Methods:In this randomized controlled study, 112 adult patients of either sex, aged 18-64 yr, with a body mass index of 19.8-28.3 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ, with estimated operation time of ≥1 h, undergoing elective bronchoscopy procedures, were assigned to one of two groups ( n=56 each) using a random number table method: ciprofol group (C group) and propofol group (P group). All the patients received total intravenous anesthesia. The induction dose of ciprofol was 0.1-0.3 mg/kg, and the maintenance dose was 0.4-1.2 mg·kg -1·h -1 in group C. The induction dose of propofol was 1-3 mg/kg, and the maintenance dose was 4-12 mg·kg -1·h -1 in group P. The primary outcome was the incidence of intraoperative hypotension, and the secondary outcomes were the time of emergence from anesthesia, sleep quality, patients′ and surgeons′ satisfaction with anesthesia, and the incidence of complications within 30 days after surgery. Results:Compared with group P, the incidence of intraoperative hypotension was significantly decreased, and the time of emergence from anesthesia was shortened in group C ( P<0.05). There was no statistically significant difference in secondary outcomes between the two groups ( P>0.05). Conclusions:Ciprofol is superior to propofol in reducing the risk of intraoperative hypotension and facilitates a more rapid emergence from anesthesia in patients undergoing bronchoscopy procedures.

OBJECTIVE To investigate the current status of monitoring indicators related to the"Perioperative In-fection Control"in medical institutions above the secondary level in Guizhou Province,and to delve into the imple-mentation of key measures for infection prevention and control during the perioperative period for patients under-going surgical operations.METHODS Based on the"Implementation Plan for the'Perioperative Infection Control'Initiative in Guizhou Province",a"Case Investigation Form on Key Measures for Infection Prevention and Control During the Perioperative Period for Patients Undergoing Surgical Operation"was developed.A total of 138 medi-cal institutions participated in the case investigation,and a total of 2 128 cases were investigated.RESULTS The overall monitoring indicators for the"Perioperative Infection Control"initiative in the 138 medical institutions a-bove the secondary level in Guizhou Province were at a relatively low level.The skin cleansing compliance rate was 80.32％,the hair removal compliance rate was 16.43％,the prophylactic antibacterial drug administration rate within 0.5-1 hour before surgery was 55.94％and the antibacterial drug discontinuation rate within 24 hours after prophylactic medication for type Ⅰ incision surgeries was 56.48％.The hair removal compliance rate was higher in tertiary medical institutions(19.21％)than in secondary medical institutions(14.34％)(P=0.039).The distri-bution of the four monitoring indicators varied in clinical departments and surgery types,with statistically signifi-cant differences(P＜0.05).The preferred method for surgical site skin cleansing in medical institutions across the province was local wiping,primarily with clean water(57.21％).The primary method for hair removal was razors(68.82％),and hair removal on the day of surgery was most common(61.75％).CONCLUSIONS Conduc-ting a survey on the current status of"Perioperative Infection Control"initiative monitoring indicators in medi-cal institutions in Guizhou Province helps to understand the implementation of key measures for perioperative in-fection prevention and control and set intervention targets,thus providing references for establishing a dynam-ic monitoring indicator change mechanism.

ObjectiveTo investigate the effect and potential mechanism of caffeic acid （CA） on severe acute pancreatitis （SAP） induced by caerulein combined with lipopolysaccharide （LPS）， and to provide a basis for the research on novel drugs for the treatment of SAP. MethodsC57BL/6J mice， aged 6 weeks， were divided into control group， model group， CA group， and octreotide acetate （OA） group， with 6 mice in each group. The mice in the control group were given injection of normal saline， and those in the other groups were given intraperitoneal injection of caerulein combined with LPS to establish a mouse model of SAP. At 1 hour after the first injection of caerulein， the mice in the CA group and the OA group were given intraperitoneal injection of CA or subcutaneous injection of OA at an interval of 8 hours. The general status of the mice was observed after 24 hours of modeling， and serum， pancreas， lung， and colon samples were collected. HE staining was used to observe the histopathological changes of the pancreas and lungs， and the serum levels of α-amylase， lipase， tumor necrosis factor-α （TNF-α）， interleukin-6 （IL-6）， alanine aminotransferase， aspartate aminotransferase， and creatinine were measured. RT-PCR was used to measure the expression of proinflammatory factors in the pancreas and lungs； myeloperoxidase （MPO） immunohistochemistry was used to observe the degree of neutrophil infiltration； Western blot was used to measure the activation of nuclear factor-kappa B （NF-κB） and the level of citrullinated histone H3 （CitH3）， a marker for the formation of neutrophil extracellular traps （NETs）， in the pancreas and lungs， as well as the expression level of ZO-1 in colon tissue. A one-way analysis of variance was used for comparison of continuous data between multiple groups， and the Dunnett’s t-test was used for further comparison between two groups. ResultsCompared with the control group， the model group had severe injury in the pancreas and lungs and significant increases in the activity of serum α- amylase and lipase and the levels of the proinflammatory cytokines IL-6， interleukin-1β （IL-1β）， and TNF-α in serum and lung tissue （all P<0.05）， as well as significant increases in NF-κB activation， neutrophil infiltration， and the formation of NETs in the pancreas and lungs （all P<0.05）. Compared with the model group， the CA group had alleviated pathological injury of the pancreas and lungs and significant reductions in the activity of serum α-amylase and the levels of the proinflammatory cytokines IL-6， IL-1β， and TNF-α in serum and lung tissue （all P<0.05）， as well as significant reductions in NF-κB activation， neutrophil infiltration， and the formation of NETs in the pancreas and lungs （all P<0.05）. ConclusionCA can alleviate SAP induced by caerulein combined with LPS in mice， possibly by inhibiting neutrophil recruitment and the formation of NETs.

Objective Summarize the endocrine characteristics of 5 children with Wiedemann-Steiner syndrome(WDSTS)to enhance the early recognition capability of clinicians for this condition.Methods A retrospective analysis of the medical history,clinical manifestations,genetic testing,and treatment of 5 children with Wiedemann-Steiner syndrome treated in the endocrinology department of capital center for children's health,capital medical university from October 2020 to December 2024,summarizing the clinical characteristics of the disease.Results Among the 5 cases of WDSTS,there were 2 males and 3 females,with ages ranging from 1.9 to 10 years at the time of diagnosis.Cases 1 and 3 were born prematurely,and cases 1,2 and 5 were diagnosed as small for gestational age(SGA)infants.All 5 children exhibited distinctive facial features,hirsutism,sacral dimple,developmental delay,and adenoid hypertrophy,premature tooth replacement,feeding difficulties,and a high incidence of urinary system abnormalities.Four children complained of slow growth.Cases 1 and 4 were diagnosed with short stature.Cases 3 and 5 had normal height but were slightly shorter with advanced bone age.Case 5 also experienced early puberty.Case 2 was diagnosed with premature adrenarche and idiopathic central precocious puberty due to the presence of pubic hair and breast enlargement.Cases 1 and 3 were treated with recombinant human growth hormone(rhGH),which resulted in significant height growth(approximately 10 cm/year).However,treatment was discontinued in Case 1 due to a significant advancement in bone age.Conclusions WDSTS should be considered in patients presenting with short stature,distinctive facial features,hirsutism,developmental delay,and multiple system deformities.While rhGH treatment can help improve height in these patients,the potential for accelerated bone age maturation during treatment requires careful monitoring.

Objective:To analyze the burden and trends of noncommunicable chronic disease(NCD) attributable to metabolic factors in China from 1990 to 2021.Methods:Data from the Global Burden of Diseases(GBD) 2021 database were utilized to describe changes in mortality and disability-adjusted life years(DALYs) of NCD in China from 1990 to 2021. Stratified analyses were conducted by age, sex, sociodemographic index(SDI), and related risk factors. Statistical analyses and predictions were conducted using the age-period-cohort model and the Nordpred model.Results:In 2021, the age-standardized mortality rate and age-standardized DALYs rate of NCD attributable to metabolic factors in China were 227.56 per 100 000 and 4 829.39 per 100 000, respectively. Their average annual percentage changes were -0.76%( P<0.001) and -0.77%( P<0.001). Overall, the burden decreased progressively with higher SDI levels. Analysis using the age-period-cohort model indicated reduced birth cohort and period effects for metabolic factor-attributable NCD, while age effects rose significantly. The minimum relative risk( RR) value was observed in the 15-19 age group( RR=0.01), and the maximum RR value occurred in the 95-99 age group( RR=996.86). The overall rising mortality trend indicated that age effects are the predominant driver at present. Projections estimate that by 2046, deaths from metabolic factor-attributable NCD in China will reach 8 189 563, with an age-standardized mortality rate of 236.95 per 100 000. Conclusions:China continues to face a substantial burden of NCD linked to metabolic factors, with older adults, males, and individuals with hypertension, diabetes, and prediabetes identified as key populations requiring targeted interventions.

Objective:To evaluate the effect of ciprofol on intraoperative hypotension in patients undergoing bronchoscopy procedures.Methods:In this randomized controlled study, 112 adult patients of either sex, aged 18-64 yr, with a body mass index of 19.8-28.3 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ, with estimated operation time of ≥1 h, undergoing elective bronchoscopy procedures, were assigned to one of two groups ( n=56 each) using a random number table method: ciprofol group (C group) and propofol group (P group). All the patients received total intravenous anesthesia. The induction dose of ciprofol was 0.1-0.3 mg/kg, and the maintenance dose was 0.4-1.2 mg·kg -1·h -1 in group C. The induction dose of propofol was 1-3 mg/kg, and the maintenance dose was 4-12 mg·kg -1·h -1 in group P. The primary outcome was the incidence of intraoperative hypotension, and the secondary outcomes were the time of emergence from anesthesia, sleep quality, patients′ and surgeons′ satisfaction with anesthesia, and the incidence of complications within 30 days after surgery. Results:Compared with group P, the incidence of intraoperative hypotension was significantly decreased, and the time of emergence from anesthesia was shortened in group C ( P<0.05). There was no statistically significant difference in secondary outcomes between the two groups ( P>0.05). Conclusions:Ciprofol is superior to propofol in reducing the risk of intraoperative hypotension and facilitates a more rapid emergence from anesthesia in patients undergoing bronchoscopy procedures.

Objective:To analyze the clinical and genetic characteristics of children diagnosed with Noonan-syndrome associated with loose anagen hair (NS-LAH).Methods:A retrospective analysis was conducted on the clinical data of 5 children diagnosed with NS-LAH by the Endocrinology Department of the Capital Institute of Pediatrics from January 2018 to June 2024. This analysis encompassed the patients′ demographic information, clinical manifestations, distinguishing features, treatment regimens, and prognostic outcomes to elucidate their clinical characteristics. Additionally, whole-exome sequencing and Sanger sequencing were utilized to investigate the genetic etiology within the families, and the identified variations were interpreted according to the guidelines of the American College of Medical Genetics and Genomics.Results:Among the 5 NS-LAH patients, there were 3 boys and 2 girls, with ages at diagnosis ranging from 2.3 to 7.7 years old. All patients presented with short stature as a primary complaint. Birth histories were generally unremarkable, though case 2 and 5 of macrosomia were noted. In addition to the characteristic facial features of Noonan syndrome, short stature, and varying degrees of intellectual and motor developmental delay, all 5 patients exhibited sparse hair that was easily shed, as well as enlarged head circumferences. Four patients showed structural cardiac abnormalities, which included a case of hypertrophic cardiomyopathy, 2 cases of atrial septal defect, and 1 case of patent foramen ovale. Genetic analysis revealed heterozygous missense variantion in SHOC2 gene in 4 patients, comprising 3 cases with c.4A>G (p.S2G) and one case with c.519G>C (p.M173I). Additionally, one patient was found to have a heterozygous missense variantion c.146C>G (p.P49R) in PPP1CB gene. Three children were diagnosed with growth hormone deficiency and treated with growth hormone for 1.7, 2.7 and 0.5 years. This resulted in significant improvements in height, with annual increases of 11.8, 8.4 and 13.0 cm, respectively. Among the 4 patients with SHOC2 variantions, 2 developed systemic lupus erythematosus and 1 exhibited symptoms of arthritis.Conclusions:Growth failure is the primary complaint in patients with NS-LAH. Key characteristic findings include enlarged head circumference and sparse, loose hair. Growth hormone deficiency is commonly associated with NS-LAH, and growth hormone therapy is generally effective. Furthermore, patients carrying the classic variantion in SHOC2 (c.4A>G) may have an increased risk of developing autoimmune diseases.
