Abnormal topology of cortical thickness covariance network and altered functional connectivity in patients with anti-N-methyl-D-aspartate receptor encephalitis / 中华行为医学与脑科学杂志

Objective:To explore the changes in topological attributes of structural covariance network based on cortical thickness and the brain functional activities in patients with anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis by graph theory and functional connectivity (FC) analyses, and to investigate whether these changes were correlated to cognitive impairment.Methods:A total of 33 patients with anti-NMDAR encephalitis from Department of Neurology of the First Affiliated Hospital of Guangxi Medical University(patient group) and 35 healthy controls(control group) with matched gender, age, and education were included from July 2018 to November 2021.All subjects received cognitive function assessments, structural and functional magnetic resonance imaging scans.Structural covariance networks were constructed in the two groups based on cortical thickness values and topological characteristics of networks were computed.A non-parametric permutation test which repeated 1 000 times was used to compare the characteristics of the networks between the two groups.Brain regions with abnormal topology were defined as region of interest(ROI), and FC values in global brain level were calculated.SPM 12 and RESTplus were used to identify the brain regions with significant differences in FC values between the two groups.Finally, Spearman correlation analysis between FC values of significant brain regions and cognitive scores were performed by SPSS 24.0.Results:The cognitive score of patients with anti-NMDAR encephalitis (27.0(23.5, 28.0)) was lower than that in control group(29.0(27.0, 30.0)) ( Z=-3.029, P=0.002). Graph theory analysis found that the patients showed significantly increased clustering coefficients ( P=0.004) and decreased global efficiency ( P=0.004) compared with healthy controls.Moreover, the nodal efficiency of left ventral posterior cingulate cortex (vPCC) and right dorsal posterior cingulate cortex (dPCC), as well as the nodal degree centrality of left vPCC and left polar planum of superior temporal gyrus (ppSTG) in patient group were significantly decreased ( P<0.05, FDR corrected) compared with control group.FC analysis showed the increased FC values between left vPCC and posterior cerebellum (MNI: x=6, y=-66, z=-21), as well as between left ppSTG and anterior cerebellum (MNI: x=6, y=-54, z=-12) (GRF corrected, voxel level P<0.001, cluster level P<0.05) in patient grooup.The FC values between left vPCC and posterior cerebellum were negatively correlated with the cognitive scores ( r=-0.403, P=0.020). Conclusion:Patients with anti-NMDAR encephalitis show abnormal topology of structural covariance network based on cortical thickness and altered FC values, some of which are correlated to cognition and may be the underlying neural mechanism of cognitive impairment in patients with anti-NMDAR encephalitis.

Daidzein affects proliferation and apoptosis in non-small cell lung cancer cells:role of p53 signaling pathway / 中国药理学通报

Aim To investigate the effects of daidzeinDD on the proliferation and apoptosis of non-small cell lung cancer cells,with a focus on the possible role of the p53 signaling pathway in this regard. Methods CCK-8 method and flow cytometry were used to detect the effects of soy isoflavone crude extract and DD on the viability and apoptosis of HELF and H1299 cells. Gene microarray was used to detect the changes in gene expression after treatment of H1299 cells with DD. GSEA and differential analysis were used to screen the major pathways and key genes. RT-qPCR and Western blot were performed to verify the differences in mRNA and protein expression of key genesp53 and CASP9 in the major pathways. After p53 inhibitor Pifithrin-α inhibited the expression of p53,the effect of DD on p53 mRNA and protein expression levels was examined,and the proliferative effect on H1299 cells was observed.

Serum from patients with ankylosing spondylitis can increase PPARD, fra-1, MMP7, OPG and RANKL expression in MG63 cells

OBJECTIVES: To explore the effects of serum from patients with ankylosing spondylitis on the canonical Wnt/β-catenin pathway and to assess whether the serum has an osteogenic effect in MG63 cells. METHODS: MG63 cells were cultured with serum from 45 ankylosing spondylitis patients, 30 healthy controls, or 45 rheumatoid arthritis patients. The relative PPARD, fra-1, MMP7, OPG and RANKL mRNA levels were measured using quantitative real-time polymerase chain reaction. Associations between gene expression and patient demographics and clinical assessments were then analyzed. RESULTS: MG63 cells treated with serum from ankylosing spondylitis patients had higher PPARD, fra-1, MMP7 and OPG gene expression than did cells treated with serum from controls or rheumatoid arthritis patients (all p<0.05). RANKL expression was higher in MG63 cells treated with serum from patients with ankylosing spondylitis or rheumatoid arthritis than in those treated with serum from controls (both p<0.05). The OPG/RANKL ratio was also higher in MG63 cells treated with serum from ankylosing spondylitis patients than in those treated with serum from controls (p<0.05). No associations were found between the expression of the five genes and the patient demographics and clinical assessments (all p>0.05). CONCLUSIONS : Serum from ankylosing spondylitis patients increases PPARD, fra-1, MMP7, OPG and RANKL expression and the OPG/RANKL ratio in MG63 cells; these effects may be due to the stimulatory effect of the serum on the Wnt pathway.

Recent advances in DNA vaccines against allergic airway disease: a review / 临床耳鼻咽喉头颈外科杂志

DNA vaccine is used in infectious diseases initially, and later is applied in neoplastic diseases, allergic diseases and other fields with the further understanding of DNA vaccine and the development of genetic engineering. DNA vaccine transfers the genes encoding exogenous antigens to plasmid vector and then is introduced into organism. It controls the antigen proteins synthesis, thus induces specific humoral and cellular immune responses. So it has a broad application prospect in allergic diseases. Compared with the traditional protein vaccines used in specific immunotherapy, DNA vaccine has many advantages, including high purity and specificity, and improvement of patients' compliance etc. However, there are still two unsolved problems. First, the transfection rate of unmodified naked DNA plasmid is not high, Second, it's difficult to induce ideal immune response. In this study, we will review the progress of DNA vaccine applications in respiratory allergic diseases and its various optimization strategies.

Trends in the survival of patients with nasopharyngeal carcinoma between 1976 and 2005 in Sihui, China: a population-based study / 癌症

Both the incidence and mortality of nasopharyngeal carcinoma(NPC) have decreased in Hong Kong and Taiwan but not in mainland China. The goal of this study was to analyze trends in NPC patient survival between 1976 and 2005 in Sihui, an area of mainland China with a population at high risk for NPC. A total of 1,761 patients diagnosed with NPC between 1976 and 2005 according to the records of Sihui Cancer Registry were followed to the end of 2006. We determined their observed and relative survival rates and used Cox proportional hazards regression analysis to predict prognosis. Our results showed that the 5-year and 10-year observed survival rates of NPC patients in Sihui were 50.5% and 36.9%, respectively, and the median survival time was 5.1 years. The 5-year observed survival rate of NPC patients diagnosed after 2000 was 69.8%, significantly higher than that of patients diagnosed between 1976 and 1985 (42.5%; P < 0.001, relative risk = 0.28). Similarly, the 5-year relative survival rate was 84.8% between 2000 and 2005 but 51.8% between 1976 and 1985. Besides date of diagnosis, other prognostic factors included patient sex and age and NPC clinical stage and histologic type. The relative risks of death from NPC were 0.76 [95% confidence interval (CI): 0.65-0.90] for female comparing to male and 1.28 (95% CI: 1.00-1.64) for WHO type I comparing to WHO types II and III. For the eldest age group and the latest clinical stage group, the relative risks were 2.22 (95% CI: 1.73-2.84) and 3.41 (95% CI: 2.34-4.49), respectively. Our results indicate that the survival of NPC patients in Sihui has significantly increased in recent years and this increase is not influenced by patient's sex, age, histologic type, and clinical stage. A reduction in mortality rate is expected in coming years.

A Case of Spontaneous Pneumoperitoneum Caused by Giant Bulla / 대한내과학회지

A spontaneous pneumoperitoneum is air in the peritoneal space that is detectable radiologically and can be managed successfully by observation alone or a laparotomy. A 73-year-old man was admitted for low back pain. He had a giant bulla in the left upper lung, detected radiologically 7 years earlier. On admission, he had free air in the subphrenic area bilaterally, while the previous giant bulla was not seen. Based on the physical examination, we thought that the new free air did not indicate a surgical abdomen, and performed additional examinations to rule out other disease. There was no abnormal finding linked to the free air. The free air had almost disappeared on a subsequent chest X-ray. We report a rare case of spontaneous pneumoperitoneum caused by a giant bulla, with a literature review

Transurethral Rescetion Syndrome after Transurethral Resection of Bladder Tumor in 2 Patients on Maintenance Hemodialysis / 대한신장학회지

Transurethral resection syndrome (TURS) is one of the complications of endoscopic transurethral operation with irrigation fluid. TURS comprehensively refer to several clinical symptoms and signs caused by intravascular absorbtion of irrigation fluid, hypertension, bradycardia, arrhythmia, respiratory distress, hypotension, confusion, blindness, seizure, coma, hyponatremia, and hypoosmolarity. TURS is mainly known as the complication of the transurethral resection of prostate (TURP), and rarely found in the procedures such as transurethral resection of bladder tumor (TUR-BT), hysteroscopy, cystoscopy, and arthroscopy. Only a few cases of TURS after TUR-BT have been reported. The patients on maintenance hemodialysis were restricted in the amount of water intake for volume control. They were susceptible to the absorption of irrigation fluid during TUR-BT since they had anuria. We hereby report the 2 cases maintenance hemodialysis patients who were led to TURS after TUR-BT.

A Case of Recurrent C1q Nephropathy Treated by Immunosuppressant Combination Therapy / 대한신장학회지

The definition of C1q nephropathy has been categorized since 1985. However, the clinical correlation and pathophysiology has not yet been fully revealed. Therefore, the treatment of C1q nephropathy has not been established. Our subject was a 23 year-old female patient with both leg edema and oliguria, who was presented with weight gain. Renal biopsy confirmed C1q nephropathy. Prednisolone and cyclosporine therapy was selected for treatment. After 2 weeks of treatment, the patient lost 8 kg of body weight and all laboratory examination results were normalized. Both leg edema and oliguria were resolved. After 21 weeks of regular follow-up, she stopped the medicine by herself. Eight weeks later, the patient came to the Emergency room because both leg edema recurred. Same regimen was administered for 3 weeks, and complete remission was achieved again.
