Objective To investigate the effect of intermittent low flow oxygen inhalation on cognitive function in patients with vascular dementia. Methods 116 cases of vascular dementia were divided into treatment group (n=58) and control group (n=58). Both groups received the routine drugs, and the treatment group received intermittent low flow oxygen inhalation in addition. They were assessed with the Mini Mental Statement Examination (MMSE) and Activity of Daily Living Scale (ADL) before and 8, 16 weeks after treatment. Results There was not significant difference between groups in scores of MMSE and ADL 8 weeks after treatment, but was 16 weeks after treatment (P<0.01). Conclusion Intermittent low flow oxygen inhalation can improve the cognitive function and quality of life in patients with vascular dementia.

ABSTRACT:Objective To explore the changes of serum cytokine interleukin-17 (IL-17)in patients with chronic hepatitis B of different clinical types and its clinical significance.Methods We selected 30 cases of mild chronic hepatitis B,34 cases of moderate one,29 cases of severe one,38 cases of liver cirrhosis,and 21 cases of acute on chronic liver failure.Another 30 cases over the same period served as the healthy control group.Cytokine IL-1 7 level in peripheral blood was detected in each group,and all the groups except the control group were detected for liver function and HBV-DNA.These related serum markers were detected and the results were statistically analyzed.Results ① IL-17 in the peripheral blood was (8.103±2.061)ng/mL in healthy control group;(25.551 ±7.078)ng/mL,(45.442±18.358)ng/mL and (75.378±19.05)ng/mL in the groups with mild,moderate and severe chronic hepatitis B;and (97.16±17.066)ng/mL in acute on chronic liver failure group.Its levels gradually increased with the severity;and there were significantly different among the five groups and between every two groups (P<0.01).The peripheral blood level of IL-17 was (8.103±2.061)ng/mL in the healthy control group, (34.517±8.905)ng/mL in compensatory cirrhosis group,and (45.615±15.623)ng/mL in the decompensated cirrhosis group.These three groups had pairwise comparison,and the difference between every two groups was significant (P<0 .0 1 ).The peripheral blood level of IL-1 7 in the decompensated cirrhosis group increased compared with that in the compensatory group.③ In the 1 5 2 cases detected,serum IL-1 7 level and serum ALT,AST,TBIL,HBV-DNA levels were positively correlated,and serum PTA had negative correlation with the level of IL-1 7 .④ In the 2 1 cases of acute on chronic liver failure,the peripheral blood level of IL-1 7 did not significantly differ between antigen-e positive and negative groups (P=0.654).⑤ In 21 patients with chronic on acute liver failure,the level of IL-1 7 in peripheral serum and MELD scores showed a positive correlation by Pearson correlation analysis (r=0.533,P=0.013).Conclusion In patients with chronic hepatitis B,the level of IL-17 in peripheral serum increased with disease severity.Moreover,the level of IL-1 7 in peripheral blood may play a role in promoting the progression of cirrhosis and the development of acute on chronic liver failure.

To observe the influence of the placental apoptosis on the expression of Bax,Bcl-2, Fas, FasLand TNF-α during the second trimester of pregnancy, mice of experimental group were intraperitoneal injected with 100 purified Toxoplasma gondii tachyzoites added in 0.2mL of PBS, while those of the control group were injected with 0.2 mL of sterile PBS (0.01 mol/L, pH 7.4) in the 8-th day of pregnancy. During the 12, 14, 16 and 18-th days of pregnancy, 5 mice both in experimental and control group were randomly killed and the expression levels of the apoptosis-related proteins Bax, Bcl-2, Fas, FasL and TNF-α in the placental tissues were determined by means of immunohistochemical methods. It was showed that the apoptosis-related protein expressed both in villus and decidua of the placenta, most of which were expressed in syneytiotrophoblast (ST). The positive cells with expression of Bax, Fas, FasL and TNF-α increased along with the increase of the pregnant days in both the experimental group and the control group, and the positive cells with expression of Bcl-2 decreased along with the increase of the pregnant days. It was also demonstrated that the positive cells with expression of Bax, Fas, FasL and TNF-α of the experimental group showed a higher percentage of expression than that of the control group on the same pregnant days, but the positive cells with Bcl-2 expression of the experimental group were fewer than that of the control group. It is concluded that the expression of apoptosis-related protein Bax, Bcl-2, Fas, FasL and TNF-α in the placenta were altered when the pregnant mice were infected with Toxoplasma gondii during the second trimester, which may induce the apoptosis through the endogenic and ectogenic pathway.

OBJECTIVE: To explore the genetic basis for a juvenile with maturity-onset diabetes of the young type 12(MODY12). METHODS: High-throughput sequencing was carried out to screen for the variants. Candidate variant was verified by Sanger sequencing. Pathogenity of the variant was predicted by searching the genetic databases and analysis by using bioinformatic software. RESULTS: Genetic testing indicated that the patient and his mother have both carried a heterozygous c.3976G>A variant (p.Glu1326Lys) in exon 32 of the ABCC8 gene. Prediction of the protein structure suggested the variant to be deleterious. Based on the guidelines of the American College of Medical Genetics and Genomics, the variant was predicted to be uncertain significance. CONCLUSION Whether the c.3976G>A variant of the ABCC8 gene is the cause of the disease in this patient or not depends on the functional studies and more case data. Above finding has enriched the spectrum of ABCC8 gene variants.

ObjectiveTo explore the effect of Xianlian Jiedu prescription （XLJDP） on the proliferation and glycolysis of human colorectal cancer HCT-116 cells and the underlying mechanism. MethodHCT-116 cells were cultured with XLJDP and then the survival rate was examined by methyl thiazolyl tetrazolium （MTT） assay. The effect on the HCT116 cell proliferation was detected by colony formation assay and 5-ethynyl-2′-deoxyuridine （EDU） incorporation assay. The amount of glucose consumed by HCT-116 cells was measured by glucose test kit， and the amount of produced lactic acid was determined by lactic acid test kit 48 h after the treatment with XLJDP. The expression of glycolysis-related proteins mammalian target of rapamycin （mTOR）， phosphorylated mTOR （p-mTOR）， glucose transporter 1 （GLUT1）， and lactate dehydrogenase （LDHA） was detected by Western blot. ResultThe half-maximal inhibitory concentration （IC₅₀） of XLJDP against HCT-116 cells was 6.82 g·L^-1. Compared with the blank group， XLJDP （1.625， 3.25， 6.50 g·L^-1） inhibited the proliferation of HCT-116 cells （P<0.05， P<0.01）. Moreover， compared with the blank group， XLJDP （1.625， 3.25， 6.50 g·L^-1） suppressed glucose uptake and lactic acid production in a dose-dependent manner （P<0.05， P<0.01）. The expression of p-mTOR/mTOR， LDHA， and GLUT1 was down-regulated by XLJDP （P<0.05， P<0.01）. ConclusionXLJDP can significantly inhibit the proliferation and the Warburg effect of glycolysis in colorectal cancer cells by regulating the mTOR signaling pathway and the down-regulating the expression of LDHA， GLUT1， and other key proteins and enzymes in glycolysis.

Entinostat plus exemestane in hormone receptor-positive (HR+) advanced breast cancer (ABC) previously showed encouraging outcomes. This multicenter phase 3 trial evaluated the efficacy and safety of entinostat plus exemestane in Chinese patients with HR + ABC that relapsed/progressed after ≥1 endocrine therapy. Patients were randomized (2:1) to oral exemestane 25 mg/day plus entinostat (n = 235) or placebo (n = 119) 5 mg/week in 28-day cycles. The primary endpoint was the independent radiographic committee (IRC)-assessed progression-free survival (PFS). The median age was 52 (range, 28-75) years and 222 (62.7%) patients were postmenopausal. CDK4/6 inhibitors and fulvestrant were previously used in 23 (6.5%) and 92 (26.0%) patients, respectively. The baseline characteristics were comparable between the entinostat and placebo groups. The median PFS was 6.32 (95% CI, 5.30-9.11) and 3.72 (95% CI, 1.91-5.49) months in the entinostat and placebo groups (HR, 0.76; 95% CI, 0.58-0.98; P = 0.046), respectively. Grade ≥3 adverse events (AEs) occurred in 154 (65.5%) patients in the entinostat group versus 23 (19.3%) in the placebo group, and the most common grade ≥3 treatment-related AEs were neutropenia [103 (43.8%)], thrombocytopenia [20 (8.5%)], and leucopenia [15 (6.4%)]. Entinostat plus exemestane significantly improved PFS compared with exemestane, with generally manageable toxicities in HR + ABC (ClinicalTrials.gov #NCT03538171).
