Objective To evaluate the clinical effect of minimally invasive treatment of clavicle fracture with a hollow screw.Methods Data of 65 patients,who had undergone minimally invasive treatment with a hollow screw for clavicle fracture from April 2009 to October 2010,were retrospectively analyzed.There were 41 males and 24 females,aged from 19 to 67 years (average,35.8 years).According to the Craig's classification,there were 29 of group I and 36 of group Ⅱ-Ⅱ.A 4-5 cm transverse incision was made to expose the clavicle fracture.A guide pin was inserted into the marrow cavity,and then moved towards the acromion,after the fracture was reduced the pin was moved back to the proximal clavicle,finally a hollow screw was implanted to fix the fracture.The Neer score was used to evaluate the function of the shoulder.Radiographs were taken to observe the condition of the fracture union.The operative duration,intra-operative blood loss,fracture healing time,Neer score,and complications were compared with those of 65 patients with clavicle fracture who were treated by the same surgeons with plates.Results The incision length was 4-5 cm in hollow screw group and 10-11 cm in plate group.X-rays showed bone union was achieved in both groups,and the average bone healing time was 13.2±6.9 weeks in hollow screw group and 16.3±8.7 weeks in plate group.All patients were followed up for 6 to 20 months (average,10.6 months).The average Neer score was 96.6±3.4 in hollow screw group and 94.2±5.8 in plate group.There was no infection,local skin necrosis and fracture nonunion in both groups.In hollow screw group,screw loosing occurred in 5,and fracture displacement in 3,fortunately,the fracture healed by controlling activities.There was a significant difference in fracture healing time between two groups.However,no significant difference was observed between two groups in Neer score.Conclusion Minimally invasive treatment of clavicle fracture with a hollow screw has several advantages,such as mini-invasion,short bone healing time,good clinical outcomes,and lower expense.

Objective:To evaluate the levels of interleukin 18(IL-18) mRNA in peripheral blood mononuclear cells(PBMCs),livers and spleens in monkey endotoxic shock models.Methods:Cynomolgus monkeys were injected i.v. with lipopolysaccharide(LPS) (2.8 mg/kg) to prepare the endotoxic shock models. The mRNA levels of IL-18 in PBMCs,livers and spleens were tested by fluorescence semi-quantitative realtime reverse transcription(RT)-PCR and compared with that of TNF-? and IL-1?.Results:IL-18 mRNA expression in PBMCs remarkably increased at 120 min after LPS administration, so did in livers and in spleens at the same time. mRNA levels of TNF-? in PBMCs peaked at 60 min after LPS injection, and also increased markedly at 120 min in livers and spleens. IL-1? mRNA levels peaked at 60 min in PBMCs, and did not change so much in livers and in spleens.Conclusion:IL-18 mRNA expression in PBMCs can be up-regulated by LPS, but changed latterly than TNF-? and IL-1? in endotoxic shock cynomolgus monkeys. It is presumed that IL-18 can be produced by PBMCs and liver Kupffer cells(maybe splenic macrophages),and TNF-? is produced by a variety of cells, but IL-1? in bloodstream mainly come from PBMCs after LPS challenge.
3.Status and progress of ultra-early oral feeding after esophagectomy
Chinese Journal of Thoracic and Cardiovascular Surgery 2023;39(3):168-172
There are postoperative trauma and complications associated with the esophageal resection, and patients with esophageal cancer often have different degrees of malnutrition. Therefore, nutritional support after esophagectomy is very important. Oral feeding is regarded as a symbol of successful esophagectomy and initial recovery. As a hot spot of clinical research, early oral feeding plays an important part of accelerating recovery from gastrointestinal surgery, but there is no unified clinical strategy. This review checks the relevant clinical trials at home and abroad, and summarizes the strategies of oral feeding after esophagectomy, including the timing of feeding, pre-eating inspection, dietary content, chewing methods and appetite stimulating drugs.

Objective To investigate the prevalence of DUOX2 mutations in Chinese patients with congenital hypothyroidism (CH) and to discuss the inheritance pattern of DUOX2 gene.Methods Blood samples were collected from 91 CH children and their genomic DNA was extracted from peripheral blood leukocytes.All exons and exon-intron boundaries of DUOX2 were analyzed by target next-generation sequencing and family trios was established to study the inheritance pattern of DUOX2 gene.Results Fifty-four out of 91 children with CH carried DUOX2 mutation, with a prevalence of 59.34%.Of the 54 CH children, 36 carried DUOX2 biallelic mutations.In all 12 family trios with probands carrying biallelic DUOX2 mutations, the parents carried heterozygous DUOX2 mutations while still showing normal thyroid function, suggesting that CH caused by DUOX2 mutations is inherited in an autosomal recessive manner.Conclusion DUOX2 gene is one of the most frequently mutated genes in Chinese CH patients and its inheritance pattern is an autosomal recessive one.

Objective To investigate vascular remodeling and low-density lipoprotein(LDL)deposition,the growth and development trends of lateral branch plaques in bifurcated vessels,and the potential locations of subsequent plaque growth due to the presence of plaques.Methods An idealized model of bifurcated vessels was established and the distribution of wall shear stress before and after the growth of edge-branch plaques was obtained using computational fluid dynamics.Seven sections were intercepted in the areas of low shear stress:planes 1-3 were the low shear stress areas on the lateral branch before plaque formation,planes 4-5 were the proximal and distal edges of the plaque,and planes 6-7 were the lower shear stress areas of the plaque.Vascular remodeling and LDL deposition in the cross section were simulated.The growth and development trends of plaques are also discussed.Results Among planes 1-3,plane 2 produced obvious negative remodeling and the highest concentration of LDL deposition(102.266 mmol/L),thereby indicating that this was the initial location of the atherosclerotic plaque.Compared to plane 4,plane 5 produced more pronounced vascular remodeling,lumen narrowing,and the highest deposition concentration(110.17 mmol/L)after plaque formation,which indicated that the patch had a tendency for eccentric growth downstream.Compared to plane 6,plane 7(blood flow separation reattachment site)produced more negative remodeling and the highest deposition concentration(93.851 mmol/L),thereby indicating the possibility of new plaque formation near the reattachment point of blood flow separation.Conclusions Obvious vascular remodeling at low shear stress in the lateral branches leads to lumen stenosis and high LDL deposition,thus,forming atherosclerotic plaques.The lateral wall of the bifurcated blood vessels is the initial location of atherosclerotic plaque growth.After growth,the plaque tends to develop downstream,and subsequent plaques may form at the flow separation and reattachment points.

Objective:To investigate the transcriptional changes of host factors in human rhabdomyosarcoma cells (RD) infected with echovirus 11 (E11), and to preliminarily understand the effect of polo like kinase 1(PLK1)on E11 replication and possible molecular mechanism.Methods:Transcriptome sequencing (RNA SEQ) was used to analyze the differentially expressed genes between E11 infected RD cells group and RD cell control group. Gene ontology (GO) and Kyoto encyclopedia of genes and genomes (KEGG) was used to enrich and analyze significantly differentially expressed genes. The expression situation of the representative differentially expressed genes were validated by quantitative real-time polymerase chain reaction (qRT-PCR), and the effect of PLK1 inhibition on E11 replication was preliminarily explored.Results:A total of 3 726 differentially expressed genes were identified in RD cells infected with E11, and 484 differentially expressed genes were found in the infected group (0 h, 12 h, 24 h and 48 h after infection). These differentially expressed genes were mainly enriched in the immune response, intracellular signal transduction, transcription factor activity, sequence-specific DNA binding, protein kinase activity, nuclear and membrane components, and PI3K-Akt signaling pathway. qPCR was used to verify the expression of six target genes (CXCL14, IFITM1, OAS1, SAMD9, MX1 and PLK1), which were consistent with result of RNA-Seq. The expression of CXCL14, IFITM1, OAS1, SAMD9, and MX1 were up-regulated by 1.2-104.97 times, and the expression of PLK1 was down regulated by 1-5.79 times. Inhibition of PLK1 increased E11 replication.Conclusions:Inflammatory response, PI3K-Akt, MAPK and other pathways may play an important role in the antiviral immune process of E11 infection. In addition, host factor PLK1 may play a key role in E11 infection by regulating the cell cycle.
