In order to investigate the mechanical response of lumbar vertebrae during gait cycle in adolescents with idiopathic scoliosis (AIS), the present study was based on computed tomography (CT) data of AIS patients to construct model of the left support phase (ML) and model of the right support phase (MR), respectively. Firstly, material properties, boundary conditions and load loading were set to simulate the lumbar vertebra-pelvis model. Then, the difference of stress and displacement in the lumbar spine between ML and MR was compared based on the stress and displacement cloud map. The results showed that in ML, the lumbar stress was mostly distributed on the convex side, while in MR, it was mostly distributed on the concave side. The stress of the two types of stress mainly gathered near the vertebral arch plate, and the stress of the vertebral arch plate was transmitted to the vertebral body through the pedicle with the progress of gait. The average stress of the intervertebral tissue in MR was greater than that in ML, and the difference of stress on the convex and convex side was greater. The displacement of lumbar vertebrae in ML decreased gradually from L1 to L5. The opposite is true in MR. In conclusion, this study can accurately quantify the stress on the lumbar spine during gait, and may provide guidance for brace design and clinical decision making.

Objective:To detect the pathogen and clinically diagnose for a suspected case of Neisseria meningitidis with positive blood culture result, and assess the risk of disease transmission among the community. Methods:Blood sample was collected for Neisseria meningitidis isolation and culture. Pathogen identification and serogroup typing were conducted by colony morphology, Gram staining, biochemical tests, latex agglutination test, slide agglutination test, and nucleic acid testing. The susceptibility to 12 antibiotics was also tested. Epidemiological investigation was conducted on the case, and epidemic control measures were also implemented. Results:Through various detection, the suspected case was diagnosed as Neisseria meningitidis invasive infection. The isolated strain belonged to group Y serotype, type 767 (multilocus sequence typing), and the ST167 clonal complex. The strain was sensitive to nine antibiotics, including penicillin, ampicillin, and meropenem. It exhibited intermediate sensitivity to ciprofloxacin and levofloxacin, and resistance to methicillin/sulfamethoxazole. Close contacts of the case and environmental testing results were negative. Conclusions:The case is confirmed to be an invasive infection caused by group Y Neisseria meningitidis, the ST167 clonal complex. Epidemiological investigation shows a relatively low risk of epidemic transmission. Continuous monitoring and surveillance are necessary for further assessment.

Objective:To evaluate whether underdilated stent could reduce the occurrence of hepatic encephalopathy (HE) after transjugular intrahepatic portosystemic shunt (TIPS) creation.Methods:A total of 197 patients with decompensated liver cirrhosis, who had underwent TIPS creation at Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, were analyzed retrospectively, including 110 males and 87 females with age 25-79 (54±11) years old. Uncovered and covered stents with 8 mm diameter were implanted in all subjects, and then dilated by balloon catheters with 6 mm or 8 mm diameter. The patients were divided into two groups, including underdilated group (6 mm, n=105) and control group (8 mm, n=92).Kaplan-Meier curves were used to illustrate cumulative rate of HE, and the differences were assessed with the log-rank test. Multivariate analyses with a Cox regression model were conducted to explore the risk factors for HE. Results:During a median follow-up period of 29 (12-54) months, 16 (15.2%) patients developed HE in the underdilated group and 27 (29.3%) patients in the control group. There was a significant difference in the cumulative rate of HE ( P=0.014), but no statistical differences were found in terms of variceal rebleeding, shunt dysfunction and survival between the two groups ( P=0.608, P=0.659, P=0.968). In multivariated analysis, group assignment (underdilated vs. control, HR=0.291, 95% CI 0.125-0.674, P=0.004) was identified as an independent risk factor for HE after TIPS creation. Conclusion:Underdilated TIPS could reduced the risk of HE compared with completely dilated TIPS, with comparable risk of variceal rebleeding, shunt dysfunction and mortality. And it is worthy of applying this technique to a large sample of patients in clinical practice.

Patients with type 2 diabetes mellitus (T2DM) have a large demand for dental implants, but the pathologic state of T2DM patients could compromise the efficacy of implant treatment. Glycemic control can improve the success rate of implants in the T2DM population, but the early osseointegration of individuals still needs to be improved. Strengthening early osseointegration in patients with T2DM is one of the urgent problems for clinicians. The pharmacological mechanisms of hypoglycemic drugs on the market for bone metabolism are different and may require different interventions on the bone around the implant, but there is a lack of direct clinical evidence of the protective effect of hypoglycemic drugs. This review integrated the bone metabolic effect of drugs in clinical medical research and dental implant research. The aim was to provide medication guidance for T2DM patients who require implant surgery, and it is recommended to avoid the use of drugs with negative effects on bone as far as possible without violating the clinical medication guidelines, including SGLT-2 inhibitors and thiazolidinediones. Instead, they should choose glucose-lowering drugs that are beneficial to bone metabolism, such as insulin, metformin and GLP-1 receptor agonists. However, the comparative clinical effects of these drugs on periimplant bone need to be further elucidated. The researcher should select appropriate drugs (incretin drugs) to enhance the early osseointegration of implants in patients with T2DM.
