Objective:To analyze the value of magnetic resonance T 2 mapping in the diagnosis of early cervical disc degeneration in adolescents. Methods Patients who underwent cervical MRI examination and magnetic resonance T 2 mapping in Wenzhou Hospital of Traditional Chinese Medicine between November 2019 and September 2020 were included in this study. They were divided into observation and control groups ( n = 50 per group) according to the time of lowering their heads (≥ 2 hours) every day. The T 2 values corresponding to the nucleus pulposus of cervical intervertebral disc in each segment was compared between the two groups. Cervical disk degeneration was graded using the Pfirrmann classification. T 2 value was compared between different Pfirrmann disc grades. The efficacy of T 2 value in the diagnosis of early cervical disc degeneration in adolescents was evaluated using the receiver operating characteristic curve. The specificity and sensitivity of T 2 value in the diagnosis of early cervical disc degeneration in adolescents and the area under the receiver operating characteristic curve were calculated. Results:T 2 value measured in each cervical intervertebral disc segment in the observation group was significantly greater than that in the control group ( t = 5.06, 4.47, 3.57, 2.93, 4.98 for C2-3, C3-4, C4-5, C5-6, C6-7 segments, all P < 0.05). In the observation group, the number of patients with Pfirrmann grade II cervical intervertebral disc degeneration was highest, accounting for 42% (21/50). There was a significant difference in cervical intervertebral disc segment T 2 value between different Pfirrmann disc grades ( t = 2.62, P = 0.018, vs. Pfirrmann disc grade I ; t = 2.12, P = 0.045, vs. Pfirrmann disc grade II; t = 2.24, P = 0.049, vs. Pfirrmann disc grade III). The higher Pfirrmann grade, the lower T 2 value of cervical intervertebral disc nucleus pulposus. The receiver operating characteristic curve showed that the sensitivity and specificity of T 2 value in the diagnosis of early cervical disc degeneration and the area under the receiver operating characteristic curve were 81.2%, 79.8% and 0.756, respectively. Conclusion:T 2 mapping imaging technology can predict early cervical intervertebral disc degeneration in adolescents by quantitatively analyzing the T 2 value of cervical intervertebral disc nucleus pulposus and has a high value in the diagnosis of cervical intervertebral disc degeneration. This achievement is of innovation and science.

A case report of periprosthetic hip clostridium perfringens infection 13 years after total hip arthroplasty, the patient had hip pain with fever for one week. Physical examination and imaging examination confirmed the periprosthetic joint infection. The pathogenic bacterium was clostridium perfringens according to bacterial culture, and the pathogenic bacterium of clostridium perfringens was suspected relating to the gallbladder disease in this patient. Considering such periprosthetic joint infection was early stage hematogenous periprosthetic joint infection, treatment of debridement, retention of the prosthesis, irrigating, and indwelling drainage tube were conducted. By reviewing literature about periprosthetic clostridium perfringens infection, only seven reports of periprosthetic joint infection were caused by clostridium perfringens, which were all case reports. From the previous case reports and our case, we found that the infection around the prosthesis caused by clostridium perfringens was limited to the area around the joint, and prognosis of such cases may not be as severe as the natural gas gangrene which developed very rapidly, but great attention should be paid to. The hematogenous periprosthetic joint infection caused by clostridium perfringens who had gastrointestinal symptoms in the early stage should be highly suspicious of gallbladder lesions and thorough debridement, retention of the prosthesis, irrigating and indwelling drainage tube maybe a treatment method.

Marine sponges of the genus are well known as rich sources of diverse and complex biologically relevant natural products, including alkaloids, terpenoids, peptides, lipids, and steroids. Some of these metabolites, with novel structures and promising biological activities, have attracted a lot of attention from chemists seeking to perform their total synthesis in parallel to intensive biological studies towards new drug leads. In this review, we summarized the distribution of the chemically investigated sponges, the isolation, synthesis and biological activities of their secondary metabolites, covering the literature from 1982 to early 2018.

Zinc levels are high in pancreatic β-cells, and zinc is involved in the synthesis, processing and secretion of insulin in these cells. However, precisely how cellular zinc homeostasis is regulated in pancreatic β-cells is poorly understood. By screening the expression of 14 Slc39a metal importer family member genes, we found that the zinc transporter Slc39a5 is significantly down-regulated in pancreatic β-cells in diabetic db/db mice, obese ob/ob mice and high-fat diet-fed mice. Moreover, β-cell-specific Slc39a5 knockout mice have impaired insulin secretion. In addition, Slc39a5-deficient pancreatic islets have reduced glucose tolerance accompanied by reduced expression of Pgc-1α and its downstream target gene Glut2. The down-regulation of Glut2 in Slc39a5-deficient islets was rescued using agonists of Sirt1, Pgc-1α and Ppar-γ. At the mechanistic level, we found that Slc39a5-mediated zinc influx induces Glut2 expression via Sirt1-mediated Pgc-1α activation. These findings suggest that Slc39a5 may serve as a possible therapeutic target for diabetes-related conditions.

Objective To investigate the effectiveness and safety in patients with largeartery occlusive acute cerebral infarction who received multi-interventional modes mainly with mechanical thrombectomy and its related factors affecting prognosis. Methods The clinical data of 56 patients with large artery occlusive acute cerebral infarction were analyzed retrospectively. The clinical characteristics (gender,age,and underlying diseases),timing of treatment (time from ictus to puncture,time from puncture to recanalization), multi-interventional mode therapies (intra-arterial thrombolysis,thrombectomy,balloon dilation,and stenting, etc. ),and distribution of offending vessels were observed. The modified Thrombolysis in Cerebral Ischemia Scale (mTICI)grade was used to evaluate revascularization. The National Institute of Health Stroke Scale (NIHSS)score was used to observe the neurological function at 24 h before and after procedures. The modified Rankin scale (mRS)was used to evaluate the prognosis at 3 months after procedure. The safety of the treatment was evaluated with operative complications (mainly symptomatic intracranial hemorrhage)and mortality. The patients were divided into either a good prognosis group (n = 34;mRS≤2)or a poor prognosis group (n =22;mRS≥3)according to the prognosis at 3 months after procedure. They were analyzed with univariate analysis. The factors influencing the prognosis were further analyzed with multivariate logistic regression analysis. Results (1)The recanalization rate in 56 patients was 78. 6%(n = 44),in which basilar artery was the highest,reaching 93. 8% (15 / 16),middle cerebral artery was 87. 0% (20 / 23). The NIHSS score at 24 hours was 10 ± 7,it was lower than 16 ± 6 on admission. There was significant difference (t =6. 401,P <0. 01). At 3 months,34 patients (60. 7%)had good prognosis,4 (7. 1%)died,and 8 (14. 3%) had symptomatic intracranial hemorrhage. (2)Multiple factor analysis showed that the high level of recanalization was a protective factor for good prognosis (OR,0. 465,95% CI 0. 267 -0. 809,P =0. 007). Diabetes was an independent risk factor for poor prognosis (OR,5. 535,95% CI 1. 101 -27. 835, P = 0. 038). Conclusion Acute large artery occlusive cerebral infarction treated with the intra-arterial multi-interventional modes may quickly and effectively restore intracranial blood flow. It has the characteris-tics of high recanalization rate and good prognosis,and the higher the level of recanalization,the better the prognosis. Diabetes is an independent risk factor for poor prognosis.
