RESUMO
Objective: To investigate outcomes of laryngotracheal reconstruction (LTR)with anterior and posterior costal cartilage grafts in severe pediatric subglottic stenosis (SGS) or laryngeal web (LW). Methods: A review of patients with severe subglottic stenosis or laryngeal web between January 2020 and January 2022 was performed. Demographic features including gender, age at diagnosis, age at surgery, etiology, airway support, and other comorbidities were collected preoperatively. Patients were evaluated in surgical site, breathing, swallowing, phonation and complications postoperatively.Descriptive analysis was used in this research. Results: Eight patients were included: six with grade Ⅲ SGS following Cotton-Myer grading scale, and two with type Ⅲ LW following Cohen's classification. All patients underwent LTR with anterior and posterior costal cartilage grafts. Five patients underwent single-stage LTR (ssLTR), and three patients underwent double-stage LTR (dsLTR). Seven out of eight patients were able to successfully extubate or decannulate with normal swallowing function; four patients had mild hoarseness, and three had moderate hoarseness. One patient failed in extubation, and underwent tracheotomy. Conclusions: LTR with anterior and posterior costal cartilage grafts is an effective and safe treatment for severe SGS or LW. Careful preoperative assessment of disease severity and overall medical status will help selection between ssLTR and dsLTR, thereby maximizing patient outcomes for both modalities.

Objective To estimate knee adduction moment (KAM) and knee flexion moment (KFM) under different gait test conditions via an inertial sensor network (ISN). Methods Twelve healthy young male subjects wore eight inertial sensors (located in the trunk, pelvis, both thighs, both shanks, both feet) and walked under different test conditions (changing foot progression angle, trunk sway angle, step width and walking speed). An ISN was used to extract biomechanical features as the input of recurrent neural network (RNN), so as to estimate the KAM and KFM. Results The overall KAM estimation accuracy: relative root mean square error (rRMSE) was 8.54% and r=0.84. The overall KFM estimation accuracy was rRMSE=6.40% and r=0.94. Conclusions The model can be used as the basis for load estimation of knee joints out of the lab and its potential application includes gait training and rehabilitation assessment after knee surgery.
RESUMO
The clinical data of a child diagnosed with β-ketothiolase deficiency in Children′s Hospital of Chongqing Medical University in September 2018 were reviewed, and nutritional intervention and follow-up were carried out.The male child was 1 year and 4 months old, and he had clinical manifestations, including vomiting, diarrhea, mental depression and repeated metabolic acid poisoning.Gene detection: heterozygous variation of ACAT1 gene c. 401T>C (p.M134T) and c. 481T > C (p.Y161H). This study was mainly aimed at children with β-ketothiolase deficiency for nutritional treatment of individualized nutrition therapy, suggests that energy supply should be guaranteed and protein and fat intake should be limited in acute stage, and protein and fat intake should be increased gradually in remission stage, which can not only ensure growth and development, but also reduce the occurrence of metabolic crisis.
RESUMO
Objective To study the epidemiologic characters of influenza in Shanghai from 2013 to 2015 . Methods Data of outpatient visits for influenza-like illness ( ILI ) were collected through influenza surveillance hospitals .Pathogenic surveillance to part of ILI samples was conducted . Results From 2013 to 2015, the ILI consultation rate ranged from 0.68%~3.73%, with an average rate of 1 .46%.In total 51 445 samples were collected , and 12673 samples were positive , with the positive rate of 24 .63%.The ratio of the patient visited for ILI aged from 25 to 60 was higher than other groups . Conclusion The peak of epidemic of influenza in Shanghai was in winter and summer .The ratio of the patients visited for ILI aged over 60 increased with years .More measures should be taken to protect the elder people .
RESUMO
Through study on the correlation between atractylodis lactones ingredient content and climatic factors, we research regionalization from climatic of five main producing provinces of the country, in order to provide a scientific basis for atractylodis' conscious cultivation. By sampling from 40 origins which from five main producing provinces of the country, we use SPSS to analysis variation of atractylodis lactones ingredient content in different conditions of climatic factors and the effect of each factors. Then according to the relationship between atractylodis lactones ingredient content and climatic factors, we use ArcGIS to conduct ecological suitability regionalization based on climatic factors. The most suitable climatic condition for cultivation of atractylodis: the wettest month precipitation 220-230 mm, the warmest average temperature 25 degrees C, the average temperature of driest season 10 degrees C.

Through study on the correlation between Atractylodis macrocephala lactones ingredient content and topographic factors, we researched regionalization from topography of five main producing provinces of the country, in order to provide a scientific basis for A. macrocephala reasonable cultivation. By sampling from 40 origins of five main producing provinces of the country, the variation of A. macrocephala lactones ingredient content in different conditions of topographic factors and the effect of altitude, slope and aspect was analyzed by SPSS. Then according to the relationship between A. macrocephala lactones ingredient content and topographic factors, the ecological suitability regionalization was conducted by using ArcGIS based on topographic factors. It is suitable for growth of A. macrocephala in the hilly and mountainous areas of southern whose A. macrocephala lactones ingredient content is in high levels. It is unsuitable for growth of A. macrocephala in Northern plain areas, but we can cultivate A. macrocephala in the hilly and mountainous areas of Northern. The most suitable topographic condition for cultivation of A. macrocephala : altitude 200 meters above, slope 3.00-4.99 degrees.

<p><b>OBJECTIVE</b>To study the effect of laryngotracheal reconstruction (LTR) in children with subglottic stenosis (SGS), and to discuss the indications and the risks of intraoperative and postoperative treatment of LTR.</p><p><b>METHODS</b>From September 2008 to February 2010, 5 children (4 girls and 1 boy, aged 4 to 6 years) were treated by LTR. Among the 5 children, there were 2 congenital SGS and 3 acquired SGS. One had mild grade III SGS, 3 had severe grade III SGS, and one had grade IV SGS. One child with mild III SGS was treated by single-stage LTR, and the rest four children were treated by double-stage LTR. The surgical technique consisted of cricoid lamina midline vertical incision, rib cartilage graft interposition and endotracheal tube (ETT) stenting for 2 to 3 weeks.</p><p><b>RESULTS</b>Four children with grade III SGS were de-cannulated 3 months after operation, and the child with grade IV SGS got de-cannulated 6 months after operation. Of all children, rib cartilage graft grower well, and the size of subglottis were amplified by grade III SGS to grade I SGS, and grade IV SGS to grade II SGS. All children obtained stable airway. One child with grade IV SGS who had hoarseness got effective phonation during follow-up 2 years after operation.</p><p><b>CONCLUSIONS</b>LTR is a safe and effective treatment for pediatric subglottic stenosis. The important factors of successful operation are correct assessment and evaluation of the severity and overall medical status and selection of suitable surgical techniques.</p>
