RÉSUMÉ

Objective:To evaluate the efficacy of esketamine combined with propofol for colonic transendoscopic enteral tubing (TET) in pediatric patients with autism.Methods:Sixty pediatric patients with autism of both sexes, aged 3-12 yr, weighing 15-45 kg, of American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ, who underwent painless transendoscopic enteral tubing (TET) from October 2022 to August 2023, were selected and divided into 2 groups ( n=30 each) by a random number table method: normal saline + propofol group (group NP) and esketamine + propofol group (group EP). In group NP, normal saline 10 ml was intravenously injected, and 30 s later propofol 2.0 mg/kg was given. In group EP, esketamine 0.3 mg/kg (diluted to 10 ml in normal saline) was intravenously injected, and 30 s later propofol 2.0 mg/kg was given. TET was performed when the Modified Observer′s Assessment of Alertness/Sedation Scale score ≤2. Propofol 0.5-1.0 mg/kg was added if the sedation depth was not enough, and the Modified Observer′s Assessment of Alertness/Sedation Scale score was maintained ≤2 until the end of surgery. The degree of body movement during TET was observed and recorded. The injection pain during induction, total consumption of propofol, operation time, spontaneous emergence time, and completion of operation were recorded. Adverse reactions such as respiratory depression, nausea and vomiting, hypotension, bradycardia, and postoperative agitation were recorded during operation and in the emergence period. Results:Compared with group NP, the degree of intraoperative body movement was significantly lighter, the total consumption of propofol and incidence of injection pain and intraoperative hypotension were significantly lower, and no significant change was found in the spontaneous emergence time and incidence of adverse reactions during recovery in group EP ( P<0.05). Conclusions:Esketamine (0.3 mg/kg) combined with propofol (2.0 mg/kg) can be safely and effectively used for colonic TET in pediatric patients with autism, and esketamine does not increase the risk of adverse reactions during resuscitation in a resuscitation strategy without early awakening.

RÉSUMÉ

Objective:To analyze, with Wuhan as an example, the problems found in the infrastructure development of China′s healthcare institutions, and put forward optimization suggestions for future epidemic prevention and control.Methods:From May to June 2020, we surveyed with questionnaires 56 healthcare institutions in Wuhan, covering such aspects as basic information of the institutions, infectious disease infrastructure readiness, and the converted wards for COVID-19. Statistical descriptions were used to analyze data so acquired.Results:The number of beds in the infectious departments of healthcare institutions in Wuhan amounted to 1.64 per 10 000 people, yet the existing 1 873 beds and about 5 000 convertible beds failed to meet the medical needs against the outbreak of COVID-19. After the outbreak, a total of 19 084 convertible beds were set up, of which general hospitals accounted for 88%; the area occupied by each converted bed in traditional Chinese medicine hospitals, hospitals of traditional and Western medicine, and maternal and child hospitals (<30.0m 2) was lower than that in general hospitals and specialist hospitals (>40.0m 2). Conclusions:Healthcare institutions should scientifically allocate " peacetime-wartime adaptive" hospital beds, optimize both the number and efficiency of these beds, and prepare for the worst scenarios, so that the infrastructure can be built and maintained in strict accordance with standards, government departments can rationally arrange infectious disease prevention and control facilities and strengthen their planning in case of emergencies.

RÉSUMÉ

Objective To study epidemiological characteristics of thelazjasis, in Zunyi and surrounding areas, morphology and 18S rRNA gene sequence of Thelazia callipaeda. Methods The Thelazia callipaeda was collected from several hospitals, including affiliated Hospital of Zunyi Medical College and Zunyi Aerospace Hospital, in Zunyi region since 2011 to 2015. Clinical data of infected human thelaziasis, including the patients' gender, age, residence and pets such as cats or dogs, were analyzed to find out the factors influencing the incidence. Morphology characteristics of female and male Thelazia callipaeda were observed under microscope. 18S rRNA gene of Zunyi Thelazia callipaeda was amplified by PCR, and the evolutional relationship was analyzed through the software MEGA 7.01 based on neighbour-joining (NJ) method. Homology was campared with 18S rRNA gene from GenBank in National Center of Biotechnology. Results Totally 25 cases had been reported during the study, of which 22 cases had more details. Based on the cases, we found the thelaziasis was increasing year by year. For instance, 2 cases (9.1%) were reported in 2011, 1 case (4.5%) in 2012, 3 cases in 2013 (13.6%), 10 cases (45.5%) in 2014 and 6 cases (27.3%) in 2015 . During the five years , totally 15 cases were treated between August and November, when the human thelaziasis was in typical epidemic peaks. We analyzed characteristics of the total cases reported to date. Most of the cases occurred in rural areas (20 cases). Majority of patients lived in rural region. And most cases were between 30 to 60 years old, indicating no age limit, especially, there were two cases who were at the ages of 8.5 months and 77 years old, respectively. Moreover, more women suffered from the disease than that in men, of which, the case number was 16 in women and 6 in men, and there were 7 cases who had cats or dogs at home. Under light microscope, the edge of Thelazia callipaeda had serrated cuticle with transverse striations. And male worm had a sharp peak at the tail end of Thelazia callipaeda, which cured to the ventrite and had two copulatory spicules, long one and short one, respectively. While female worm had a blunt tail, containing numerous eggs and rounded first-stage larvaes in a single line in the distal area of the uterus, near the vulva. Sequences of Thelazia callipaeda 18S rRNA gene from Zunyi and Oita Japan (AB538282.1) were showed homology of 100%, and they were clustered in a same branch of Phylogenetic tree. Conclusions Human thelaziasis cases in Zunyi region are increasing each year, and most of the cases have occurred in rural areas. 18S rRNA gene has a high homology with sequence AB538282.1 in Thelazia callipaeda. Combining clinical data, analysis of epidemiological characteristics and the characteristics of 18S rRNA should be good for specie identification and epidemiological analysis.

<p><b>OBJECTIVE</b>To characterize the biological function of calmodulin (CaM) from Clonorchis sinensis (C. sinensis, Cs) and investigate its role in clonorchiasis-associated hepatic fibrosis.</p><p><b>METHODS</b>The full-length sequence of CsCaM gene was isolated from Cs cDNA library and its homologues were searched using BLASTx for comparison. Bioinformatics analysis was performed to compare the homologues and predict the physiochemical characteristics and functional domains. The gene was cloned in a prokaryotic plasmid and expressed in E. coli, and the recombinant protein was purified by affinity chromatography for immunizing rats to produce polyclonal antibodies, whose titer was determined using ELISA analysis. Immunoblotting analysis was carried out to determine of the purity and antibody recognition of CsCaM. Immunofluorescence assay was employed to analyze the tissue location of the protein. A rat model of liver fibrosis was established by introperitoneal injection of the recombinant protein.</p><p><b>RESULTS</b>The recombinant CsCaM protein obtained contained 150 amino acids with a theoretical molecular mass of 23.4 kD. CsCaM homologue had EF hand motifs. The recombinant pET-30a-CsCaM plasmid expressed in BL21 E. coli was about 23.4 kD. The total IgG antibody titer in the immunized mice reached the peak level (over 1: 51200) 2 to 4 weeks after the first injection. Immunohistochemistry showed that CsCaM located in the testis of adult C. sinensis. The rats receiving intraperitoneal injection of CsCaM showed severe liver inflammation with mild to moderate liver fibrosis.</p><p><b>CONCLUSION</b>The pro-inflammation and pro-fibrosis effects of CsCaM in rat liver suggest its involvement in clonorchiasis- associated hepatic fibrosis.</p>

RÉSUMÉ

BACKGROUND: Peripheral nerve injuries are hoped to promote the regeneration of nerve repair by elevating brain-derived neurotrophic factor (BDNF) concentration in local injury regions. OBJECTIVE: To observe the recanalization of nerve fiber and motor function in sciatic nerve injury rats following BDNF gene-modified bone marrow mesenchymal stem cells (BMSCs). DESIGN, TIME AND SETTING: The randomized, controlled animal study was performed at the Fujian Institute of Neurology from May 2007 to May 2008. MATERIALS: Femur and tibia of F344 male rats aged 2 months were sterilely harvested to prepare BMSCs. BDNF gene-modified BMSCs were prepared using constructed chronic viral vector PNL-BDNF-IRES2-EGFP. METHODS: The right sciatic nerve injury models were made using 60 adult Sprague Dawley rats. All models were randomly assigned into phosphate buffer saline (PBS) group, BMSC group and BDNF gene-modified BMSC group. 2 ?L BPS, 2 ?L BMSC solution and 2 ?L BDNF modified BMSC solution were separately transfered into injury site of each group. MAIN OUTCOME MEASURES: The retrograde horseradish peroxidase tracing was practiced to observe neural cell number in the Lumbar 4 and 5 spinal cord anterior horn at 2 and 4 weeks after microinjection. Sciatic nerve function index was used to observe rat motor function of injured limbs. Fluorescence excitation and immunohistochemistry were employed to detect BMSC survival and BDNF expression. RESULTS: Cell number was more, and nerve function recovery was better in the Lumbar 4 and 5 spinal cord anterior horn in the BDNF gene-modified BMSC group than in the PBS and BMSC groups. BMSC survival was found in the injured sites in the BMSC and BDNF gene-modified BMSC groups. BDNF expression was significantly more in the BDNF gene-modified BMSC group than in the BMSC group. CONCLUSION: BDNF gene-modified BMSCs have promotion effects on the recanalization and functional recovery of nerve fiber following peripheral nerve injury.
