Objective To analyze the influencing factors of plastic bronchitis in children with Mycoplasma pneumoniae infection and put forward targeted prevention suggestions. Methods The clinical data of children with Mycoplasma pneumoniae infection who were admitted to Chengdu Third People's Hospital from September 2022 to February 2024 were retrospectively analyzed . According to whether plastic bronchitis occurred, they were divided into plastic group (n=118) and non-plastic group (n=184), and the differences between the two groups were compared and analyzed. Univariate and multivariate logistics regression analysis equations were used to analyze the independent influencing factors of plastic bronchitis in children with mycoplasma pneumoniae infection. Results Among the 302 children with Mycoplasma pneumoniae infection , 118 cases were diagnosed with plastic bronchitis. Analysis showed that the children’s age, duration of fever, hospital stay, pleural effusion rate, number of bronchoscopic lavage, allergy history, endoscopic mucosal erosion rate, WBC, NE%, LY%, CRP, LDH, PCT and D-D were the single factors influencing the occurrence of plastic bronchitis in children with mycoplasma pneumoniae infection. Binary logistics regression analysis revealed that age (OR=2.137, P=0.033, 95% CI: 1.132-16.603), allergy history （OR=3.028, P=0.014, 95% CI: 1.261-864), NE% (OR=2.395, P=0.031, 95% CI: 1.087-5.274), CRP (OR=3.864, P=0.004, 95% CI: 1.563-3.864), PCT (OR=4.125, P=0.001, 95% CI: 1.793-3.864), and D-D (OR=3.920, P=0.002, 95% CI: 1.632-3.864) were independent risk factors for plastic bronchitis in children with mycoplasma pneumoniae infection (P<0.05). Conclusion Age, allergy history, NE%, CRP, PCT and D-D are independent risk factors for plastic bronchitis in children with mycoplasma pneumoniae infection . It is necessary to take clinical intervention measures to reduce the occurrence risk.

Objective To investigate the effects of nalbuphine combined with dexmedetomidine on postop-erative recovery quality and pain in patients who undergoing laparoscopic bariatric surgery.Methods A total of 169 patients who underwent laparoscopic bariatric surgery at our hospital were included and divided into control group(group C),nalbuphine group(group N),dexmedetomidine group(group D),and nalbuphine combined with dexme-detomidine group(group ND)using randomised numerical table method.Group C received intravenous injection of saline,group N and group ND received intravenous injection of nalbuphine before the end of the surgery,and group D and group ND received pumping of dexmedetomidine before anesthesia induction and during surgery.Compare the postoperative recovery quality score(QoR-40),hemodynamics at different time points,visual analogue scale score(VAS),sedation-agitation scale(SAS),first time out of bed activity and exhaust time,and incidence of nausea and vomiting among four groups.Results The postoperative QoR-40 scores of patients in group ND were better than those in group C and group N(P<0.05),and the QoR-40 scores in group D were better than those in group C(P<0.05).MAP and HR were more stable during the awakening period in group ND and group D(P<0.05).Compared with group C,patients in all three groups had lower VAS scores and SAS scores(P<0.05)and consumed less remedial analgesic medication(P<0.05).In terms of adverse reactions,the incidence of postoperative nausea,vomiting and coughing in the group ND was lower than that in the group C(P<0.05).Conclusion The combination of nalbuphine and dexmedetomidine could improve the quality of postoperative recovery and pain in patients under-going laparoscopic bariatric surgery,reduce hemodynamic fluctuations during the patients′ recovery period,reduce the incidence of nausea and vomiting,and improve the patients′ prognosis.

Objective:To investigate the association between hepatic echinococcus granulosus infection and necrosis with gene polymorphism of interleukin-10 (IL-10) and tumor necrosis factor-α (TNF-α), and to identify the related factors at the gene level.Methods:A total of 106 patients with hepatic echinococcosis who underwent surgical treatment in the department of hepatobiliary surgery, People′s Hospital of Xinjiang Uygur Autonomous Region from January 2018 to December 2020 were selected. Patients with necrosis caused by hepatic echinococcus granulosus infection were selected as the observation group, and patients without necrosis caused by hepatic echinococcus granulosus infection were selected as the control group, with 53 cases in each group. The serum levels of IL-10 and TNF-α were detected by enzyme-linked immunosorbent assay (ELISA). The polymorphisms of IL-10 (-592, -1082) and TNF-α (rsl800630) were detected by polymerase chain reaction (PCR). The levels of IL-10 and TNF-α and their gene polymorphisms were analyzed.Results:The levels of serum IL-10 and TNF-α in the observation group were significantly higher than those in the control group (all P<0.05); There was significant difference in genotype and allele frequency of IL-10 (-592, -1082) and TNF-α (rsl800630) (all P<0.05). The serum IL-10 level of CC genotype patients with IL-10 gene -592C/A locus in the observation group was higher than that of CA+ AA genotype patients, with statistically significant difference ( P<0.05). The serum IL-10 level in patients with TT genotype at -1082T>A of IL-10 gene in the observation group was higher than that in patients with TA+ AA genotype, with statistically significant difference ( P<0.05). The serum TNF-α level in patients with CC genotype at rsl800630C/A locus of TNF-α gene in the observation group was higher than that in patients with CA+ AA genotype, with statistically significant difference ( P<0.05). Conclusions:The changes of IL-10 (-592, -1082) and TNF-α (rsl800630) gene polymorphisms may be associated with hepatic echinococcus granulosus infection and necrosis.

OBJECTIVE: To explore the genetic basis of three children with unexplained mental retardation/developmental delay. METHODS: Peripheral venous blood samples were collected for routine G-banding karyotyping analysis and chromosomal microarray analysis (CMA). Whole exome sequencing (WES) was also carried out for patient 3. RESULTS: The karyotypes of the 3 children were normal. The result of CMA analysis of patient 1 was arr[GRCh37]: 2q22/3(145 128 071-145 159 029)×1, with a 31 kb deletion, which was predicted to be a pathogenic copy number variation. The deletion has involved exons 8 to 10 of the ZEB2 gene. Patient 2 was arr[hg19]:2q22.3 (145 071 457-146 881 759)×1, with a 1.81 Mb deletion involving the ZEB2 and GTDC1 genes. Patient 3 was arr[GRCh37]: 9p23p23(11 698 261-12 106 261)×1, with a 408 kb deletion containing no disease-associated gene. WES has identified a c.2102C>A (p.Ser701*) variant in exon 8 of the ZEB2 gene, which was included in ClinVar database and rated as pathogenic, and verified by Sanger sequencing as a de novo variant. CONCLUSION For the substantial clinical and genetic heterogeneity of Mowat-Wilson-syndrome, CMA and WES are helpful to identify the etiology of children with developmental delay/mental retardation of unknown causes, particularly those with peculiar facial features and multiple congenital malformations.

OBJECTIVE: To analyze the genotype and clinical phenotype of a 3-month-old female infant featuring unresponsiveness. METHODS: The infant was subjected to genetic testing, and her clinical features were compared with syndromes associated with variants of the candidate gene. RESULTS: The patient has featured long fingers, long and overlapped toes, musk-like face, blepharophimosis, ptosis, and lacrimal duct anomaly. She was found to harbor a heterozygous de novo variant NM_012330.3: c.3040C>T (p.Gln1014*) in exon 16 of the KAT6B gene. Her clinical phenotype and genotype have both conformed to Say-Barber-Biesecker-Young-Simpson syndrome (SBBYSS). CONCLUSION The child was diagnosed with SBBYSS syndrome due to the c.3040C>T (p.Gln1014*) variant of the the KAT6B gene. Discovery of the unique features has expanded the phenotypic spectrum of this syndrome.

Objective:To explore the utility of the muscle redistribution technique (MRT) in the signal recognition of an intelligent bionic prosthesis.Methods:Between December 2016 and April 2017, 4 male patients were treated with muscle redistribution procedures. Among them, 3 were upper limb amputees of the distal 1/3 of the forearm, at the carpometacarpal joint and at the midcarpal joint. One was a lower limb amputee at the distal 1/3 of the lower leg. In each case, 4-6 muscles and tendons in the stump were transferred and the tendons were anchored in different areas of the skin. When the muscle contracted actively, the tendon pulled the skin, resulting in obvious deformation of the skin in different areas. The skin′s deformation, capacitance signal data and postoperative complications were used as indicators in the evaluations. To measure the capacitance signals the patients were asked to grip, flex and extend the wrist, and flex and extend the fingers , or dorsi- and plantar-flex the ankle, and flex and extend the toes. With the help of capacitance sensors the limb′s deformation was analyzed.Results:Three months after the surgery the patients were able to actively control contraction of the transferred muscle and produce skin deformation. At the final follow-up, the effective deformation rate was 80% (16/20). Two kinds of classifiers were identified by linear discriminant analysis and quadratic discriminant analysis. In the upper limb, the overall recognition accuracies were 97.27% and 100% respectively, and the recognition accuracy of each action was 100%. In the lower limb, the overall recognition accuracies were 95.32% and 100%, and the recognition accuracy of each action was again 100%. In one case wound healing was delayed and several dressing changes were required.Conclusions:MRT can effectively output motion intentions and increase the number and intensity of motion signals. The procedure provides a novel way for better control of intelligent bionic prostheses.

Insufficient volume of future liver remnant (FLR) often leads to the complications including liver failure and even death and thus remains a bottleneck for liver surgery. Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) is a newly developed two-stage hepatectomy procedure which can promote rapid regeneration of FLR, but the related mechanism has not yet been elucidated. With reference to the recent research advances in China and foreign countries, this article reviews the hemodynamic and humoral factors for ALPPS in promoting liver regeneration, the effect of ALPPS on liver parenchymal cells, and the role of non-parenchymal liver cells (including hepatic stellate cells, natural killer cells, macrophages, and liver progenitor/stem cells) in regulating liver regeneration. It is pointed out that the interaction between non-parenchymal liver cells and parenchymal cells is a hotspot in the research on the mechanism of liver regeneration after ALPPS.

Total hip arthroplasty (THA) is a well developed technique to which the spatial orientation of acetabular component is crucial. Since the idea of "safe zone" being proposed, such idea has long been obeyed by hip surgeons but has also been challenged in recent years. This is because post-operative instability could happen even if acetabular components are placed within "safe zone" . The latest researches have demonstrated that sagittal spinal balance and spino-pelvic mobility can affect the spatial orientation of acetabular components. Factors including spinal degenerative changes, long lumbosacral changes and spinal ankyloses can lead to sagittal spinal imbalance and/or influence spino-pelvic mobility, which subsequently affect pelvic retroversion. Proper pelvic retroversion is a way to compensate for sagittal spinal imbalance and is beneficial to post-operative stability. It is necessary for hip surgeons to rethink "safe zone" before performing THA and understand spinal balance as well as spinopelvic mobility. The goal is to reduce the rate of dislocation. This review started by introducing the related spinopelvic parameters frequently seen in papers published recently and the definitions of acetabular cup orientations. After the spinal sagittal balance and its compensatory mechanisms session, discussed its clinical relevance, as well as the significance of spinal mobility, in spinopelvic motion under three different postures.
