Objective To observe the clinical effects of phosphocreatine treatment on left ventricular function and on amino-terminal pro-brain natriuretic peptide (NT-proBNP) level in elderly patients with chronic heart failure. Methods In our department, the 172 elderly patients with chronic heart failure were randomly divided into treatment group and control group (n= 86, each).The control group received routine anti-heart failure treatment. The treatment group received conventional therapy plus creatine phosphate sodium for 4 weeks. The cardiac function was evaluated and the NT-proBNP level was measured in all subjects. Results Four weeks after treatment, the improvements of left ventricular ejection fraction (LVEF), left ventricular end-systolic diameter (LVESD) and left ventricular end-diastolic dimension (LVEDD) were better in treatment group than in control group (all P＜0.05). The plasma NT-proBNP level decreased significantly in treatment group as compared with control group [before treatment: (956.4 ± 644.2) pmol/L and (973.6 ±639.8) pmol/L; after treatment: (414. 5 ± 163.8 ) pmol/L and ( 719.3 ± 477. 5 ) pmol/L, all P＜0. 05]. Conclusions Phosphocreatine could improve left ventricular function and decrease plasma NT-proBNP level in elderly patients with chronic heart failure.

Objective To observe the effect of calycosin on cisplatin?induced inhibition of human gastric BGC823 cells. Methods BGC823 cells were treated with different drugs:saline,cisplatin,calycosin and cisplatin combined with calycosin. MTT assays were used to detect the prolif?eration rate of BGC823 cell. Then the protein level and RNA level of cyclin D1,CDK4 and CDK6 were detected by Western blotting and Real?time PCR. Results The proliferation inhibition rates of BGC823 cells treated with 20μg/mL cisplatin,10μg/mL meperoflavone,and combina?tion of the 2 drugs were 56.44%± 2.08%,9.52%± 2.77%and 74.44%± 0.82%,respectively. The inhibition rate of the combination of drugs was significantly higher than that of the single drug treatment group(P<0.05). In addition,we found that calycosin can significantly enhance the inhi?bition of Cyclin D1,CDK4 and CDK6 by cisplatin in protein level and RNA level. Conclusion Calycosin can significantly increase the inhibitory rate of cisplatin on BGC823 cell proliferation,and the combination of the two drugs can reduce the side effects of cisplatin.

Objective: To investigate the trends in incidence, mortality and disease burden of prostate cancer among residents at ages of 60 years and older in Zhangjiagang City, Jiangsu Province from 2006 to 2022, so as to provide insights into improvements in the prostate cancer control strategy. Methods: The incidence and mortality of prostate cancer among residents at ages of 60 years and older in Zhangjiagang City from 2006 to 2022 were collected from the Chronic Diseases Monitoring and Management System in the National Health Information Platform of Zhangjiagang City, and the crude incidence and mortality of prostate cancer were calculated and standardized to data from the sixth national population census in China in 2010. Based on the disease burden of prostate cancer captured from the 2019 Global Burden of Disease Study datasets, the years of life lost due to premature death (YLL) and years of life lived with disability (YLD) and disability-adjusted life years (DALY) due to prostate cancer were measured, and trends in incidence, mortality and disease burden of prostate cancer were analyzed using average annual percent change (AAPC). Results: The crude incidence, standardized incidence, crude mortality, standardized mortality, crude DALY rate and standardized DALY rate of prostate cancer were 89.85/105, 83.87/105, 32.31/105, 25.45/105, 546.39/105 and 483.50/105 among residents at ages of 60 years and older in Zhangjiagang City from 2006 to 2022, which all appeared a tendency towards a rise (AAPC=5.346%, 4.219%, 6.648%, 3.697%, 4.198% and 2.200%, all P<0.05). The crude incidence, mortality and DALY rate of prostate cancer all appeared a tendency towards a rise with age (all P<0.05), with a tendency towards a rise seen for the crude incidence of prostate cancer among residents at ages of 60 to 64 years, 65 to 69 years and 70 to 74 years (AAPC=4.888%, 8.086% and 3.005%, all P<0.05), and a tendency towards a rise for the crude mortality and DALY rate among residents at ages of 80 years and older (AAPC=10.243% and 9.693%, both P<0.05). Conclusion The incidence and mortality of prostate cancer showed a tendency towards a rise among residents at ages of 60 years and older in Zhangjiagang City from 2006 to 2022, and the disease burden due to prostate cancer continued to increase, with a more remarkable increasing tendency seen for the incidence of prostate cancer among residents at ages of 60 to 74 years and for the mortality among residents at ages of 80 years and older.

Objective To investigate the contribution of single nucleotide polymorphisms (SNP)variation in folate metabolism pathway genes and its interaction with environmental risk factors to the etiology of NTD. Methods In 275 families from central China, a total of 278 aborted fetal tissues or blood samples were collected from NTD individuals, 478 maternal and/or paternal blood samples were also obtained as controls. Folate supplementation, maternal diabetes mellitus and medication before pregnancy and during the first trimester of pregnancy were investigated. SNP analyses of all samples were performed by CEQ 8800. Case-parent control study and transmission/disequilibrium tests (TDT) were performed according to environmental cofactors stratification to evaluated 28 SNP in 12 folate pathway genes associated with human NTD. Results Only gene MTHFR rs1801133 was significantly associated with NTD, and synergistic effects of environmental risk factors (no folate supplementation and maternal diabetes) were shown on the occurrence of NTD. Linkage disequilibrium between BHMT rs3733890 and NTD existed in case of no folate supplementation,whereas the genotype alone did not contribute to the etiology of NTD. Other SNP were not significantly associated with NTD. Conclusions MTHFR rs1801133 is a risk factor of NTD, but BHMT rs3733890 is not an independent risk factor. Further investigations in folate and methionine cycle genes are requird in larger scale to enclose the interactions between gene and gene, or gene and environmental factors.

Aim To explore the effects and mecha-nisms of choro-oxime derivatives on spatial learning and memory impairment in Kunming mice and SD rats induced by scopolamine and Aβ1-42 , respectively. Methods 40 Kunming mice were randomly divided into 5 groups: control group, model group, donepezil treatment group, arimoclomol treatment group and TCO-2 treatment group. There were 8 mice in each group. Mice of control group were established by intra-peritoneal injection of saline, and mice of other groups were injected with scopolamine and caused memory im-pairment. Both control group and model group were treated with solvent by intraperitoneal administration;donepezil treatment group received donepezil by intra-gastric administration; arimoclomol treatment group and TCO-2 treatment group were given the correspond-ing drugs by abdominal injection, respectively. The solvent and drugs were given at the same time every morning for 8 days. Spatial learning and memory abili-ty were tested by Morris water maze from the fifth day of the drugs administration. 40 SD rats were divided into 5 groups the same as the dementia model men-tioned above. Mice of control group were established by intracerebroventricular injection of saline, and mice of other groups were injected with insoluble Aβ1-42 to be induced of memory impairment. Solvent and drugs were also delivered as mentioned above. Morris water maze was carried out from the fifth day of the drug de-livery. After that, acetyl cholinesterase activity of hip-pocampus was tested with acetyl cholinesterase reagent kit; the content of Aβ1-42 in hippocampus was meas-ured by ELISA assay kit;the expression of phosphoryl-ated tau proteins was detected by Western Blot. Re-sults In both two dementia models, choro-oxime de-rivatives could improve the spatial learning and memory ability, shorten the escape latency and increase the times of crossing the former platform. Choro-oxime de-rivatives could also inhibit the acetyl cholinesterase ac-tivity in animal brain, decrease the concentration of Aβ1-42 and the expression of phosphorylated tau pro-teins in the dementia rats’ hippocampus. Conclusions Spatial learning and memory deficits induced by sco-polamine and Aβ1-42 could be reversed by choro-oxime derivatives. It may be concerned with enhancement of the cholinergic system functions and reduction of the levels of Aβ1-42 and phosphorylated tau proteins in the brain.

Objective To explore the risk factors for lung cancer-related cerebral infarction . Methods The hospitalized active lung cancer patients on anti-cancer therapy with no traditional stroke risk factors, who experienced an acute cerebral infarct in the First Affiliated Hospital of Guangxi Medical University from January 2005 to December 2015, were consecutively collected as the LCRS ( lung cancer-related stroke) group.The active lung cancer patients without cerebral infarction hospitalized at the same peroid matched with the LCRS group for age and gender were collected as the LC ( lung cancer ) group. Clinical data from the two groups were analyzed .Results A total of 139 LCRS patients and 139 LC patients were enrolled in the study , with 110 male and 29 female in each group , and there were no significant difference for the mean age between the LCRS group (52.1 ±10.4 years old ) and the LC group (52.1 ± 10.1 years old).Two or more acute ischemic lesions of the brain were showed by MRI in most patients in the LCRS group (117 cases, 84.2%).Compared with the LC group, more patients in the LCRS group were found with adenocarcinoma , metastasis, elevated plasma D-dimer, CA125 and CA199 levels [ 88 cases (63.3%) vs 47 cases (33.8%);98 cases (70.5%) vs 56 cases (40.3%);(468.38 ±291.37) μg/L vs (277.59 ±191.22) μg/L;(221.42 ±146.34) U/ml vs (106.84 ±69.97) U/ml;(254.68 ±185.84) U/ml vs (97.15 ±63.64) U/ml;with all P<0.001].By logistic regression analysis of multiple factors , the elevated plasma D-dimer, CA125 and CA199 levels were showed to be independent risk factors for the cerebral infarction (OR=1.003, 95%CI 1.001 -1.004; OR=1.006, 95%CI 1.003 -1.010; OR=1.011, 95%CI 1.007-1.015).Conclusions The elevated plasma D-dimer, CA125 and CA199 levels are the risk factors for the lung cancer related cerebral infarction , which may lead to hypercoagulation and induce cerebral infarction eventually .
