Objective:To summarize the clinical effect of laparoscopic medial umbilical ligament dissection in two-stage Fowler-Stephens orchiopexy (FSO).Methods:A case-series study was conducted.Clinical data of children who underwent two-stage FSO from March 2020 to July 2022 in the Department of Urology, Children′s Hospital Affiliated to Zhengzhou University were retrospectively analyzed.Indexes such as operation time, amount of blood loss, degree of postoperative pain in the operative area, testicular position, size, texture and parental satisfaction at the operative side 1 month, 6 months and 1 year after surgery were collected.Measurement data of normal distribution were expressed as Mean± SD and compared using the independent sample and paired sample t-tests. Results:A total of 18 children with complete clinical data were included in this study.Their age ranged from 7 months to 10 years, with an average of 2 years.There were 10 cases of FSO on the left side and 8 cases on the right side.Twelve cases (group A) had the testis directly descending to the scrotum without amputation of the umbilical medial ligament during the operation, including 7 cases on the left side and 5 cases on the right side; 6 cases (group B) with testis not descending to the scrotum received amputation of the umbilical medial ligament, and the testicle was pulled into the scrotum without tension, including 3 cases on the left side and 3 cases on the right side.The age of patients in group A [(0.88±0.26) years] was lower than that in group B [(4.32±2.96) years] ( t=-4.11, P<0.05).The operation time of patients in group B was (47.50±1.87) min, slightly longer than that in group A [(46.17±1.47) min] ( t=-1.66, P>0.05).The intraoperative bleeding volume in group B was (5.18±0.42) mL, slightly higher than that in group A [(4.96±0.20) mL] ( t=-1.56, P>0.05).Patients in both groups had mild pain in the operative area, which could be tolerated by the children.There were no significant differences in testicular position, size, texture and satisfaction between the two groups 1 month after surgery.Reexamination at 6 months after operation showed that 1 case in group A had mild testicular retraction, located above the scrotum; no significant testicular retraction was observed in group B; the size and texture of testis in both groups had no significant change compared with those before operation, and the blood supply was normal according to the color ultrasound findings; parental satisfaction was high.Reexamination at 1 year after operation showed that 1 case of testis in group A was located above the scrotum, 2 cases had no obvious development, and the rest cases had increased testis size [(0.51±0.03) mL] compared with before operation [(0.31±0.02) mL] ( t=-22.97, P<0.05); all cases of testis in group B returned to normal position, 1 case had no obvious development, and the rest cases had increased testis size [(0.45±0.02) mL] compared with before operation [(0.24±0.01) mL] ( t=-32.87, P<0.05).There was no significant difference in testicular size increase between group A [(0.20±0.03) mL] and group B [(0.20±0.01) mL] ( t=-1.19, P>0.05). Conclusions:In the case that the medial umbilical ligament obviously affects the testicular descent, it can be dissected, which significantly shortens the distance of testis descending to the scrotum.The testicular position after surgery is normal, and the two-stage FSO does not affect the testicular development.

Disharmony between nutritive qi(ying)and defensive qi(wei)is the core pathogenesis of insomnia.The normal function of ying-wei in the generation,dispersion,divergence and aggregation is the precondition for the realization of the coordination between ying and wei.The disordered function of ying-wei in the generation,dispersion,divergence and aggregation will cause the disharmony between ying and wei,and then the insomnia occurs.For the treatment of insomnia caused by the disordered function of ying-wei in the generation,Guizhi Decoction associated prescriptions are used for strengthening middle energizer and nourishing ying and wei.For the treatment of insomnia caused by the disordered function of ying-wei in the dispersion,Mahuang Decoction associated prescriptions are used to relieve the exterior and eliminate the pathogen for insomnia patients with the manifestations of the attack of exopathogens,and Xiao Chaihu Decoction associated prescriptions are used to dredge the triple energizer for insomnia patients with the dysfunction of the triple energizer.For the treatment of insomnia caused by the disordered function of ying-wei in the divergence,Rhei Radix et Rhizoma associated bitter-cold prescriptions are used to purge the interior heat for insomnia patients with abundant interior heat syndrome,Gypsum Fibrosum associated pungent-cold prescriptions are used to release muscles and clear heat for insomnia patients with the interior heat complicated by exterior syndrome,Natrii Sulfas Exsiccatus associated salty-cold prescriptions are used to clear heat,moisten dryness and dissipate the masses for insomnia patients with interior heat complicated by dryness syndrome,sour-cold medicines are used to clear heat and remove retained water,supplement deficiency and relieve exterior for insomnia patients with interior heat complicated by water-retention syndrome,deficiency syndrome and exterior syndrome,and Ophiopogonis Radix associated prescriptions and Lillli Bulbus associated prescriptions are used to clear heat and nourish ying for insomnia patients with the consumption of ying and yin.For the treatment of insomnia caused by the disordered function of ying-wei in the aggregation,the compatibility of Poria and Cinnamomi Ramulus is used for warming yang and resolving fluid retention in patients with fluid retention,Taohong Siwu Decoction associated prescriptions are used to activate blood and remove stasis in patients with predominance of blood stasis syndrome,the compatibility of Poria and Paeoniae Radix Alba are used to treat retained water and blood stasis in patients with water-blood co-morbidity.Treating insomnia caused by disharmony between ying and wei from the perspective of the function of ying-wei in the generation,dispersion,divergence and aggregation is aimed at the core pathogenesis of insomnia,which makes the treatment easy to be carried out,and can provide reference for clinical differentiation and treatment of insomnia.

Objective To investigate the clinical characteristics and prognosis of pneumococcal meningitis(PM),and drug sensitivity of Streptococcus pneumoniae(SP)isolates in Chinese children.Methods A retrospective analysis was conducted on clinical information,laboratory data,and microbiological data of 160 hospitalized children under 15 years old with PM from January 2019 to December 2020 in 33 tertiary hospitals across the country.Results Among the 160 children with PM,there were 103 males and 57 females.The age ranged from 15 days to 15 years,with 109 cases(68.1% )aged 3 months to under 3 years.SP strains were isolated from 95 cases(59.4% )in cerebrospinal fluid cultures and from 57 cases(35.6% )in blood cultures.The positive rates of SP detection by cerebrospinal fluid metagenomic next-generation sequencing and cerebrospinal fluid SP antigen testing were 40% (35/87)and 27% (21/78),respectively.Fifty-five cases(34.4% )had one or more risk factors for purulent meningitis,113 cases(70.6% )had one or more extra-cranial infectious foci,and 18 cases(11.3% )had underlying diseases.The most common clinical symptoms were fever(147 cases,91.9% ),followed by lethargy(98 cases,61.3% )and vomiting(61 cases,38.1% ).Sixty-nine cases(43.1% )experienced intracranial complications during hospitalization,with subdural effusion and/or empyema being the most common complication[43 cases(26.9% )],followed by hydrocephalus in 24 cases(15.0% ),brain abscess in 23 cases(14.4% ),and cerebral hemorrhage in 8 cases(5.0% ).Subdural effusion and/or empyema and hydrocephalus mainly occurred in children under 1 year old,with rates of 91% (39/43)and 83% (20/24),respectively.SP strains exhibited complete sensitivity to vancomycin(100% ,75/75),linezolid(100% ,56/56),and meropenem(100% ,6/6).High sensitivity rates were also observed for levofloxacin(81% ,22/27),moxifloxacin(82% ,14/17),rifampicin(96% ,25/26),and chloramphenicol(91% ,21/23).However,low sensitivity rates were found for penicillin(16% ,11/68)and clindamycin(6% ,1/17),and SP strains were completely resistant to erythromycin(100% ,31/31).The rates of discharge with cure and improvement were 22.5% (36/160)and 66.2% (106/160),respectively,while 18 cases(11.3% )had adverse outcomes.Conclusions Pediatric PM is more common in children aged 3 months to under 3 years.Intracranial complications are more frequently observed in children under 1 year old.Fever is the most common clinical manifestation of PM,and subdural effusion/emphysema and hydrocephalus are the most frequent complications.Non-culture detection methods for cerebrospinal fluid can improve pathogen detection rates.Adverse outcomes can be noted in more than 10% of PM cases.SP strains are high sensitivity to vancomycin,linezolid,meropenem,levofloxacin,moxifloxacin,rifampicin,and chloramphenicol.[Chinese Journal of Contemporary Pediatrics,2024,26(2):131-138]

Objective To analyze the status and trend for the mortality and DALY rates of child growth failure (CGF) in children aged < 5 years in China from 1990 to 2019, so as to provide a scientific basis for CGF prevention and control. Methods The mortality and DALY rates of CGF in children aged < 5 years from 1990 to 2019 were obtained from GBD 2019. The changes of these indicators with the years in China , the United States, Japan, Russia, India and the global were compared and analyzed. Results In 2019, the mortality of child wasting, child stunting and child underweight in children aged < 5 years in China were 9.62/100 000, 1.23/100 000, and 1.29/100 000 respectively, the mortality rates were 867.50/100 000 , 129.23/100 000 , and 112.87/100 000 rescpectively, higher than those of the United States, Japan, and Russia, and far lower than those of India and the global. The disease burden of three types of CGF were all higher in males than females, and higher in children aged < 1 years than children aged 1-4 years. From 1990 to 2019, the mortality and DALY rates of CGF in children aged < 5 years in China decreased from 300.41/100 000 and 26 445.38/100 000 to 10.49/100 000 and 943.57/100 000, respectively. China had the largest drop rate compared with all analyzed countries. As for children aged < 5 years in China, the DALY rate of lower respiratory infection ranked first in all the diseases caused by CGF. Conclusion From 1990 to 2019, the disease burden of CGF in children aged < 5 years has shown a significant decrease in China , but it is still far behind the developed countries. In the future, more attention should be paid to the problems of child growth in hope of reducing the mortality and DALY rates of CGF.

Objective: To examine the safety and effectiveness of a new stent graft system for endovascular repair of abdominal aortic aneurysm(AAA). Methods: This is a prospective,multi-center,single-arm clinical trial. The patients with AAA treated with a new stent graft system were enrolled at 21 centers from September 2018 to September 2019 in China. Follow-up was performed before discharge, and at 30, 180, 360 days after operation, respectively. The primary safety endpoint was the incidence of major adverse events(MAE) within 30 days. The primary efficacy endpoint was the success rate of AAA treatment at 360 days. Secondary safety endpoints were the incidence of perioperative access complications and acute lower limb ischemia,all-cause mortality, AAA related mortality and incidence of serious adverse events (SAE) at 180 and 360 days. Secondary efficacy endpoints were the incidence of type Ⅰ or Ⅲ endoleak,stent displacement,and conversion to open surgery or re-intervention at 180 and 360 days. Results: One hundred and fifty-six patients were enrolled,including 137 males and 19 females. The age was (68.9±6.9) years (range:48.2 to 84.6 years).Maximum aneurysm diameter was (50.8±11.2) mm (range:25.0 to 85.0 mm),diameter of proximal landing zone was (21.2±2.5) mm (range:17.0 to 29.5 mm),and length of proximal landing zone was (31.4±13.0) mm (range:11.0 to 75.0 mm).The incidence of MAE was 1.3% (2/156) at 30 days,both were all-cause death cases. The success rate of AAA treatment was 88.5% (138/156) at 360 days. No perioperative access complication and acute lower limb ischemia occurred. All-cause mortality was 2.0% (3/154) at 180 days and 2.6% (4/153) at 360 days,and there was no AAA related death. The incidence of SAE was 23.0%(35/152) at 180 days and 30.5%(46/151) at 360 days, and no device-related SAE occurred. The incidence of type Ⅰor Ⅲ endoleak was 3.4% (5/147) at 180 days and 3.5% (5/144) at 360 days. Conclusion: The new stent graft system is easy to operate,and early-term safety and effectiveness results are expected.

Objective: To analyze the clinical epidemiological characteristics including composition of pathogens , clinical characteristics, and disease prognosis acute bacterial meningitis (ABM) in Chinese children. Methods: A retrospective analysis was performed on the clinical and laboratory data of 1 610 children <15 years of age with ABM in 33 tertiary hospitals in China from January 2019 to December 2020. Patients were divided into different groups according to age,<28 days group, 28 days to <3 months group, 3 months to <1 year group, 1-<5 years of age group, 5-<15 years of age group; etiology confirmed group and clinically diagnosed group according to etiology diagnosis. Non-numeric variables were analyzed with the Chi-square test or Fisher's exact test, while non-normal distrituction numeric variables were compared with nonparametric test. Results: Among 1 610 children with ABM, 955 were male and 650 were female (5 cases were not provided with gender information), and the age of onset was 1.5 (0.5, 5.5) months. There were 588 cases age from <28 days, 462 cases age from 28 days to <3 months, 302 cases age from 3 months to <1 year of age group, 156 cases in the 1-<5 years of age and 101 cases in the 5-<15 years of age. The detection rates were 38.8% (95/245) and 31.5% (70/222) of Escherichia coli and 27.8% (68/245) and 35.1% (78/222) of Streptococcus agalactiae in infants younger than 28 days of age and 28 days to 3 months of age; the detection rates of Streptococcus pneumonia, Escherichia coli, and Streptococcus agalactiae were 34.3% (61/178), 14.0% (25/178) and 13.5% (24/178) in the 3 months of age to <1 year of age group; the dominant pathogens were Streptococcus pneumoniae and the detection rate were 67.9% (74/109) and 44.4% (16/36) in the 1-<5 years of age and 5-<15 years of age . There were 9.7% (19/195) strains of Escherichia coli producing ultra-broad-spectrum β-lactamases. The positive rates of cerebrospinal fluid (CSF) culture and blood culture were 32.2% (515/1 598) and 25.0% (400/1 598), while 38.2% (126/330)and 25.3% (21/83) in CSF metagenomics next generation sequencing and Streptococcus pneumoniae antigen detection. There were 4.3% (32/790) cases of which CSF white blood cell counts were normal in etiology confirmed group. Among 1 610 children with ABM, main intracranial imaging complications were subdural effusion and (or) empyema in 349 cases (21.7%), hydrocephalus in 233 cases (14.5%), brain abscess in 178 cases (11.1%), and other cerebrovascular diseases, including encephalomalacia, cerebral infarction, and encephalatrophy, in 174 cases (10.8%). Among the 166 cases (10.3%) with unfavorable outcome, 32 cases (2.0%) died among whom 24 cases died before 1 year of age, and 37 cases (2.3%) had recurrence among whom 25 cases had recurrence within 3 weeks. The incidences of subdural effusion and (or) empyema, brain abscess and ependymitis in the etiology confirmed group were significantly higher than those in the clinically diagnosed group (26.2% (207/790) vs. 17.3% (142/820), 13.0% (103/790) vs. 9.1% (75/820), 4.6% (36/790) vs. 2.7% (22/820), χ²=18.71, 6.20, 4.07, all P<0.05), but there was no significant difference in the unfavorable outcomes, mortility, and recurrence between these 2 groups (all P>0.05). Conclusions: The onset age of ABM in children is usually within 1 year of age, especially <3 months. The common pathogens in infants <3 months of age are Escherichia coli and Streptococcus agalactiae, and the dominant pathogen in infant ≥3 months is Streptococcus pneumoniae. Subdural effusion and (or) empyema and hydrocephalus are common complications. ABM should not be excluded even if CSF white blood cell counts is within normal range. Standardized bacteriological examination should be paid more attention to increase the pathogenic detection rate. Non-culture CSF detection methods may facilitate the pathogenic diagnosis.

Bitter almonds (Semen Armeniacae Amarum) are prone to oil deterioration during storage, so they often require mashing prior to clinical use. To confirm the medical value of bitter almonds "being mashed when used" and to determine the optimal storage conditions for bitter almonds, UPLC-MS/MS was used to perform a comparative study of the chemical composition of bitter almonds in different storage states (mashed and unmashed), storage times (0, 2 and 4 weeks), and storage temperatures (25 ℃ and 4 ℃). A total of 58 substances were identified in bitter almond extracts through literature review, this group's previous work, and a Compound Discoverer software search. Statistically significant differences were found in the chemical composition and content of bitter almonds in different storage states, storage times, and storage temperatures. The results show that the chemical composition of bitter almonds stored unmashed was more stable than that of bitter almonds stored mashed; the chemical composition of bitter almonds stored at 4 ℃ was more stable than that of bitter almonds stored at 25 ℃; and the shorter the storage time, the less the chemical composition changed. Amygdalin, the main medicinal component of bitter almonds, showed statistically significant differences in content under the above three storage conditions, which can be used as a potential quality marker for bitter almonds.

Objective: To explore the safety and effectiveness of stereotactic body radiation therapy (SBRT) for oligometastases from colorectal cancer (CRC). Methods: This is a prospective, single-arm phase Ⅱ trial. Patients who had histologically proven CRC, 1 to 5 detectable liver or lung metastatic lesions with maximum diameter of any metastases ≤5 cm were eligible. SBRT was delivered to all lesions. The primary endpoint was 3-year local control (LC). The secondary endpoints were treatment-related acute toxicities of grade 3 and above, 1-year and 3-year overall survival (OS) and progression free survival (PFS). Survival analysis was performed using the Kaplan-Meier method and Log rank test. Results: Petients from 2016 to 2019 who were treated in Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College. Forty-eight patients with 60 lesions were enrolled, including 37 liver lesions and 23 lung lesions. Forty-six patients had 1 or 2 lesions, with median diameter of 1.3 cm, the median biologically effective dose (BED(10)) was 100.0 Gy. The median follow-up was 19.5 months for all lesions. Twenty-five lesions developed local failure, the median local progression free survival was 15 months. The 1-year LC, OS and PFS was 70.2% (95% CI, 63.7%~76.7%), 89.0% (95% CI, 84.3%~93.7%) and 40.4% (95%CI, 33.0%~47.8%). The univariate analysis revealed that planning target volume (PTV) and total dose were independent prognostic factors of LC (P<0.05). For liver and lung lesions, the 1-year LC, OS and PFS was 58.7% and 89.4% (P=0.015), 89.3% and 86.5% (P=0.732), 30.5% and 65.6% (P=0.024), respectively. No patients developed acute toxicity of grade 3 and above. Conclusion: SBRT is safe and effective treatment method for oligometastases from CRC under precise respiratory motion management and robust quality assurance.
