OBJECTIVES: To study the factors influencing the short-term (28 days) efficacy of initial adrenocorticotropic hormone (ACTH) therapy for infantile epileptic spasms syndrome (IESS), as well as the factors influencing recurrence and prognosis. METHODS: The clinical data were collected from the children with IESS who received ACTH therapy for the first time in the Department of Pediatric Neurology, Xiangya Hospital of Central South University, from April 2008 to January 2018 and were followed up for ≥2 years. The multivariate logistic regression analysis was used to evaluate the factors influencing the short-term efficacy of ACTH therapy, recurrence, and long-term prognosis. RESULTS: ACTH therapy achieved a control rate of seizures of 55.5% (111/200) on day 28 of treatment. Of the 111 children, 75 (67.6%) had no recurrence of seizures within 12 months of follow-up. The possibility of seizure control on day 28 of ACTH therapy in the children without focal seizures was 2.463 times that in those with focal seizures (P<0.05). The possibility of seizure control on day 28 of ACTH therapy in the children without hypsarrhythmia on electroencephalography on day 14 of ACTH therapy was 2.415 times that in those with hypsarrhythmia (P<0.05). The possibility of recurrence within 12 months after treatment was increased by 11.8% for every 1-month increase in the course of the disease (P<0.05). The possibility of moderate or severe developmental retardation or death in the children without seizure control after 28 days of ACTH therapy was 8.314 times that in those with seizure control (P<0.05). The possibility of moderate or severe developmental retardation or death in the children with structural etiology was 14.448 times that in those with unknown etiology (P<0.05). CONCLUSIONS Presence or absence of focal seizures and whether hypsarrhythmia disappears after 14 days of treatment can be used as predictors for the short-term efficacy of ACTH therapy, while the course of disease before treatment can be used as the predictor for recurrence after seizure control by ACTH therapy. The prognosis of IESS children is associated with etiology, and early control of seizures after ACTH therapy can improve long-term prognosis.

ObjectiveTo understand the physical development level of 3-7 years old children in Zhag′yab， and to provide reference for local health decision-making. MethodsA cross-sectional study was conducted between June 2021 and July 2021， with a sample of 1 247 Tibetan children aged 3-7 years from kindergartens in 13 districts of Zhag′yab. Their height and weight were measured and the hemoglobin was detected by a unified method. Standard statistical method was adopted （Z-score method）. Z-scores of length /height-for-age （HAZ）， Z-scores of weight-for-age （WAZ）， Z-scores of body mass index （BMI）-for-age （BAZ） and Z-scores of weight-for-height （WHZ） were calculated by WHO Anthro v3.2.2 and WHO Anthro Plus. The nutritional status of children was evaluated according to WHO diagnostic criteria for malnutrition and anemia. ResultsThe average WAZ and HAZ of children aged 3 to 7 in Zhag′yab were lower than the WHO standards，except for the WAZ of 4-year old， the differences were statistically significant （P<0.05）. The overall detection rate of malnutrition was 25.7%， stunting， underweight， wasting， overweight， obesity and anemia were 11.6%， 11.8%， 10.8%， 3.3%， 1.8% and 29.3%， respectively. The detection rates of all indicators in boys were higher than those in girls， and the differences were not statistically significant （P>0.05）. The overweight rate and obesity rate of rural children were lower than those of urban children， and the other detection rates were higher than those of urban children. The differences of underweight rate， obesity rate and anemia rate were statistically significant between urban and rural children （P<0.05）. Among the detection rates of all indicators in different age groups， there were statistically significant differences in the overweight rate and the anemia rate （P<0.05）. The overweight rate of children aged 4 and the anemia rate of children aged 5 were the highest. ConclusionsThe physical development of children aged 3 to 7 in Zhag′yab is poor， and the prevalence of malnutrition and anemia is high. Underweight and anemia are more serious in rural children， and the overweight and obesity problem of urban children is emerging. More attention should be paid to promote their nutritional status. The prevention and intervention of children’s malnutrition should be strengthened in Zhag′yab.

Objective To investigate the epidemiological characteristics and identify the risk factors of Giardia lamblia infections among patients with colorectal cancer in Henan Province. Methods A cross-sectional study was performed for questionnaire surveys among colorectal cancer patients in Henan Cancer Hospital during the period from March to July, 2021. Patients’ stool samples were collected, and the triosephosphate isomerase (tpi) gene of G. lamblia was amplified in stool samples using nested PCR assay to characterize the parasite genotype. Univariate analysis and multivariate logistic regression analyses were employed to identify the risk factors of G. lamblia infections among colorectal cancer patients. Results A total of 307 colorectal cancer patients were investigated, including 176 males (57.3%) and 131 females (42.7%). PCR assay detected 8.1% [95% confidential interval (CI): (0.056, 0.117)] prevalence of G. lamblia infections among the study subjects, and there was no significant difference in the prevalence between men [9.1%, 95% CI: (0.057, 0.143)] and women [6.9%, 95% CI: (0.037, 0.125)] (χ² = 0.495, P = 0.482). In addition, there was no age-specific prevalence of G. lamblia infections among the participants (χ² = 1.534, P = 0.675). Multivariate logistic regression analysis identified use of septic tanks [odds ratio (OR) = 3.336, 95% CI: (1.201, 9.267)], daily use of well water [OR = 3.042, 95% CI: (1.093, 8.465)] and raising livestock [OR = 3.740, 95% CI: (1.154, 12.121)] as risk factors of G. lamblia infections among colorectal cancer patients, and the prevalence of abdominal pain was significantly greater in colorectal cancer patients with G. lamblia infections than in those without infections (P = 0.017). Among the 25 patients with G. lamblia infections, assemblage A was characterized in 24 (96.0%) cases and assemblage B in one case (4.0%). Conclusions The prevalence of G. lamblia is high among colorectal cancer patients in Henan Province, and assemblage A is the dominant genotype of G. lamblia. Use of septic tanks, daily use of well water and raising livestock are risk factors of G. lamblia infections among patients with colorectal cancer.

OBJECTIVE: To observe clinical effect of calcium sulfate on promoting natural healing of docking sites during bone transport. METHODS: A retrospective study was performed on the patients with posttraumatic chronic osteomyelitis treated by bone transport and calcium sulfate implantation from January 2013 to January 2018. There were 23 males and 4 females, aged from 20 to 61 years old with an average of (44.30±10.00) years, the courses of disease ranged from 3 to 86 months with an average of(13.26±16.47) months. Sixteen patients with posttraumatic chronic osteomyelitis were caused by internal fixation of closed fractures, and 11 patients were caused by open fractures. The length of bone defects after debridement ranged from 4 to 14 cm with an average of(9.11±2.57) cm. Postoperative complications, natural healing rate of the docking sites, external fixation index were observed, Checketts & Otterburn pin-tract infection classification was used to evaluate pin-tract infection, and Paley evaluation criteria was used to evaluate bone and function results. RESULTS: Twenty-seven patients were followed up from 26 to 41 months with an average of (31.32±3.37) months. It did not happened skin embedded between bone stumps in all patients. All patients obtained bone union at (17.78±5.43) months after operation.Among them, 25 patients healed naturally in the docking sites, 2 patients with poor compliance healed after debridement and bone grafting in the docking sites. One patient occurred equines deformity, and no re-fracture or recurrence of infection occurred. According to Checketts & Otterburn pin tract infection classification, 22 patients (41 pin tracts)occurred pin-tract infection with varying degrees. The average external fixation index was (2.02±0.24) months/cm(ranged from 1.6 to 2.4 months/cm). According to Paley evaluation criteria, bony results showed 21 patients obtained excellent results, 5 good, and 1 moderate;functional results showed 19 patients got excellent results, 7 good, and 1 moderate. CONCLUSION During bone transport, the implantation of calcium sulfate on the bone defect areas could prevent skin embedding between the bone stumps, benefit for the natural healing of the docking sites, and could avoid the second-stage debridement and bone grafting for most patients. However, it should be noted that compliance needs to be increased.

OBJECTIVE: To study the clinical features and recurrence factors of myelin oligodendrocyte glycoprotein (MOG) antibody disease in children and the effect of recurrence prevention regimens. METHODS: A retrospective analysis was performed on the medical data of 41 children with MOG antibody disease who were hospitalized in the Department of Pediatric Neurology, Xiangya Hospital of Central South University, from December 2014 to September 2020. According to the presence or absence of recurrence, they were divided into a monophasic course group ( RESULTS: For these 41 children, acute disseminated encephalomyelitis was the most common initial manifestation and was observed in 23 children (56%). Of the 41 children, 22 (54%) experienced recurrence, with 57 recurrence events in total, among which optic neuritis was the most common event (17/57, 30%). The proportion of children in the recurrence group who were treated with corticosteroids for less than 3 months in the acute phase was higher than that in the monophasic course group (64% CONCLUSIONS More than half of the children with MOG antibody disease may experience recurrence. Most children with recurrence are treated with corticosteroids for less than 3 months in the acute phase. Rituximab and azathioprine may reduce the risk of recurrence.

Objective To explore the feasibility of rapid and sutureless anastomosis of artificial vascular replacement of abdominal aorta in dog models using magnetic compression anastomosis (MCA) technique. Methods Twelve healthy adult crossbred dogs were evenly divided into the MCA and hand suturing (HS) groups according to the anastomosis method between abdominal aorta and artificial blood vessels. The intraoperative duration of abdominal aorta occlusion, intraoperative condition of anastomotic stoma and postoperative imaging examination of anastomotic stoma were compared between two groups. Results The intraoperative duration of abdominal aorta occlusion in the MCA group was significantly shorter than that in the HS group [(5.2±2.3) min vs. (24.4±4.3) min, P < 0.001]. No anastomotic leakage of blood or anastomotic stenosis occurred in the MCA group during the operation. Intraoperative anastomotic leakage of blood occurred in all of the 6 dogs in the HS group. Among them, 1 dog died of excessive blood loss, and 2 dogs experienced mild anastomotic stenosis due to repeated repair. Postoperative color Doppler ultrasound and angiography showed smooth blood flow at the anastomotic stoma without stenosis or thrombosis in the MCA group. In the HS group, 4 dogs presented with anastomotic stenosis on angiography at postoperative 4 weeks. Conclusions MCA technique may achieve rapid and sutureless anastomosis of artificial vascular replacement of abdominal aorta in dog models, which reduces the incidence of anastomotic complications and accelerates postoperative recovery.

【Objective】 To evaluate the performance of the magnetic artificial blood vessel device for fast non-suture anastomosis of caval reconstruction with artificial blood vessel transplantation after resection in canines. 【Methods】 Sixteen adult mongrel dogs of either gender were randomly divided into two groups for vena cava reconstruction with artificial blood vessel transplantation after inferior vena cava (IVC) resection. Group MCA (n=8): magnetic artificial blood vessel device for IVC reconstruction; Group manual sewing (MS) (n=8): hand suturing for IVC reconstruction. Operation time and stoma errhysis were recorded during operation. Patency and stoma stenosis were confirmed via color Doppler ultrasound scanning and X-ray cholangiography at different time points as late as 4 weeks after surgery. 【Results】 The time required to perform the vascular anastomosis was significantly shorter for the magnetic artificial blood vessel device (6.25±2.25)min than for MS (27.32±5.12)min (P<0.001). There were four cases of stoma errhysis in MS group which had to be repaired (P=0.077). Vascular X-ray angiography and color Doppler ultrasound found normal blood flow and no stoma stenosis in MCA group, but three cases of stoma stenosis in MS groups (P=0.200). Compared with MS group, the magnetic ring device stoma was associated with smooth re-endothelialization and depressed infiltration of inflammatory cells at the anastomotic site. 【Conclusion】 The magnetic artificial blood vessel device offers a simple, fast, reliable, and efficacious technique for vena cava reconstruction with artificial blood vessel transplantation.

Autism spectrum disorder (ASD), a representative disease of children's neurodevelopmental disorders, brings huge pressure and financial burden to families and society. It is of great significance to explore its etiology and pathogenesis. Therefore, we established an ASD Cohort based on the existing China National Birth Cohort (CNBC), which applied parallel design to recruit and follow up families who achieved pregnancy after receiving assisted reproductive technologies (ART) and families with spontaneous conception. The main aims of this study are to compare the incidence of ASD among children born after ART with those born under spontaneous pregnancy, and to evaluate the impact of ART on the neurobehavioral development of offspring. Additionally, with a variety of clinical and behavioral related information collected during pregnancy and at early life of offspring, we are able to investigate the risk factors associated with ASD comprehensively. This article briefly introduces the objectives, contents, preliminary progress, strength and limitations, as well as further prospects of the ASD cohort study, mainly focusing on the overall design and current progress.

OBJECTIVE: Lung-toxin Dispelling Formula No. 1, referred to as Respiratory Detox Shot (RDS), was developed based on a classical prescription of traditional Chinese medicine (TCM) and the theoretical understanding of herbal properties within TCM. Therapeutic benefits of using RDS for both disease control and prevention, in the effort to contain the coronavirus disease 2019 (COVID-19), have been shown. However, the biochemically active constituents of RDS and their mechanisms of action are still unclear. The goal of the present study is to clarify the material foundation and action mechanism of RDS. METHODS: To conduct an analysis of RDS, an integrative analytical platform was constructed, including target prediction, protein-protein interaction (PPI) network, and cluster analysis; further, the hub genes involved in the disease-related pathways were identified, and the their corresponding compounds were used for in vitro validation of molecular docking predictions. The presence of these validated compounds was also measured in samples of the RDS formula to quantify the abundance of the biochemically active constituents. In our network pharmacological study, a total of 26 bioinformatic programs and databases were used, and six networks, covering the entire Zang-fu viscera, were constructed to comprehensively analyze the intricate connections among the compounds-targets-disease pathways-meridians of RDS. RESULTS: For all 1071 known chemical constituents of the nine ingredients in RDS, identified from established TCM databases, 157 passed drug-likeness screening and led to 339 predicted targets in the constituent-target network. Forty-two hub genes with core regulatory effects were extracted from the PPI network, and 134 compounds and 29 crucial disease pathways were implicated in the target-constituent-disease network. Twelve disease pathways attributed to the Lung-Large Intestine meridians, with six and five attributed to the Kidney-Urinary Bladder and Stomach-Spleen meridians, respectively. One-hundred and eighteen candidate constituents showed a high binding affinity with SARS-coronavirus-2 3-chymotrypsin-like protease (3CL), as indicated by molecular docking using computational pattern recognition. The in vitro activity of 22 chemical constituents of RDS was validated using the 3CL inhibition assay. Finally, using liquid chromatography mass spectrometry in data-independent analysis mode, the presence of seven out of these 22 constituents was confirmed and validated in an aqueous decoction of RDS, using reference standards in both non-targeted and targeted approaches. CONCLUSION RDS acts primarily in the Lung-Large Intestine, Kidney-Urinary Bladder and Stomach-Spleen meridians, with other Zang-fu viscera strategically covered by all nine ingredients. In the context of TCM meridian theory, the multiple components and targets of RDS contribute to RDS's dual effects of health-strengthening and pathogen-eliminating. This results in general therapeutic effects for early COVID-19 control and prevention.
