Objective To elucidate the clinical characteristics and the outcome of acute renal failure (ARF) in the elderly. Methods Clinical data of 109 elderly patients(≥60 years) with ARF were analysed and compared with that of 175 younger adult ARF patients(18 40 years) in the same period. Results 109 out of 422 patients(25 8%) with ARF were more than 60 years. The mortality rate of ARF in these patients was 58 7%. ARF was induced mainly by prerenal factors (20 2%) and sepsis (15 6%). Complications such as infections (52 3% vs 29 7%), cardiovascular events (64 2% vs 38 3%), respiratory failure (43 1% vs 20 0%) and hyperkalemia (29 4% vs 15 4%) were more prevalent in elderly patient than that in the younger adult ARF patients ( P

Objective: To explore the mediating effects of activities of daily living (ADL) and social interaction on the relationship between intergenerational support and depressive symptoms in the elderly. Methods: Basic information, ADL, social interaction and intergenerational support from children of the elderly aged 60 years and above were collected through the 2020 database of China Health and Retirement Longitudinal Study. Depressive symptoms were evaluated using the Short Version of Center for Epidemiological Studies Depression Scales, and the mediating effects of ADL and social interaction on intergenerational support and depressive symptoms in the elderly was analyzed using Process program. Results: A total of 3 174 individuals were enrolled, including 1 638 males (51.61%) and 1 536 females (48.39%), and 2 264 individuals were aged 60 to <70 years (71.33%). The median score of depressive symptoms was 8 (interquartile range, 13), with 1 346 individuals (42.41%) identified as having depressive symptoms. The median scores of intergenerational support from children, ADL, and social interaction were 2 (interquartile range, 3), 0 (interquartile range, 1) and 3 (interquartile range, 6), respectively. Intergenerational support negatively affected depressive symptoms through the independent mediating effects of ADL (effect value=-0.224, 95%CI: -0.288 to -0.161) and social interaction (effect value=-0.516, 95%CI: -0.807 to -0.228), and negatively affected depressive symptoms via the chain mediating role of ADL and social interaction (effect value=-0.184, 95%CI: -0.237 to -0.134). The total mediating effect value was -0.924, accounting for 46.67% of the total effect. Conclusion Intergenerational support has a negative indirect impact on depressive symptoms in the elderly, mediated through ADL and social interaction.

Objective To explore the down-regulation of advanced receptor for advanced glycation end products(RAGE)on expression of high mobility group protein B1(HMGB1)in glioma cells line and the volume change of transplanted tumor in nude mice. Methods HMGB1 expression in glioma LN229 cells line (divided into a control group and a study group) was observed by immunohistochemical assay and Western blot. The control group received normal saline,whereas the study group received RAGE receptor blocking agent FPS-ZM1. Expression of HMGB1 protein was detected by the same methods. The difference of the expression was examined by independent sample t test. 30 Nu/Nu nude mice were randomly divided into two groups;the above two kinds cell lines were injected into the same area of the left back of nude mice. Six weeks after injection ,the volume size was measured six times ,and the variance of repeated measurement data was used to analyze the difference of the volume change. Results HMGB1 protein was mainly expressed in the cytoplasm and nucleus. As compared with the control group,HMGB1 protein expression levels were decreased in the study group(P < 0.05),the growth rate of transplanted tumor in nude mice was significantly faster in the control group than in the study group ,the difference was statistically significant(P < 0.05). Conclusions The growth and invasion of HMGB1 protein may be involved in glioma by RAGE receptor. RAGE receptor blocker FPS-ZM1 can significantly reduce the expression of HMGB1 protein and inhibit the growth of transplanted tumor volume. It is expected to be used for the research on glioma cell apoptosis.

To construct a library of mouse single chain variable fragment (scFv) antibody against ofloxacin using phage display and recombinant antibody technique, specific anti-ofloxacin scFv was screened and 3D structure was homology modeling. Total RNA was extracted from hybridoma cell of ofloxacin mAb, and was used to amplify VH and VL gene by RT-PCR using random primer. Then they were linked by a DNA linker encoding (G1y4 Ser) 3 as VH-linker-VL sequence forming scFv by SOE(splicing by overlap extension) PCR. These fragments were inserted into phage T7 after double digestion and transformed with host bacteria BLT5403. 3 ×105 pfu / ml single chain antibody phage libraries were successfully constructed. Four positive phage scFv clones were screened by direct competitive ELISA after four times of enriched procedure in the order of adsorption-elution-amplificatio, 3D structure of specific scFv was homology modeling finally. This research lays a foundation for further massive expression of anti-ofloxacin scFv.

BACKGROUND:Liushen Pil is a traditional Chinese herbal formula, has the effects of heat-clearing and detoxicating, eliminating stagnation, detumescence and al eviating pain. Modern pharmacology verifies that Liushen Pil has anti-inflammatory, analgesic, cardiac, anti-viral, anti-tumor effects, and has been extensively used in the treatment of various infectious diseases and malignant cancer. OBJECTIVE:To investigate the inhibitory effects of Liushen Pil on esophageal cancer xenografts, and effects on microvessel density and vascular endothelial growth factor expression. METHODS:After reproducing nude mouse models of human esophageal cancer, 48 nude mice were randomly divided into high-dose Liushen Pil group, moderate-dose Liushen Pil group, low-dose Liushen Pil group, cisplatin group, model group and blank group. According to medication regimen, drugs were given. The growth of transplanted tumor of nude mice was dynamical y observed in each group. The nude mice were sacrificed after 20 days of treatment. Neoplasm weight was taken and the tumor-suppressing rate was calculated. Immunohistochemistry was used to detect microvessel density and the expression of vascular endothelial growth factor. RESULTS AND CONCLUSION:The weight of transplanted tumor was significantly lower in the high-dose Liushen Pil group, moderate-dose Liushen Pil group, low-dose Liushen Pil group, and cisplatin group than in the model group (P<0.05). Microvessel density and the expression of vascular endothelial growth factor were obviously lower in the each Liushen Pil group than in the model group, but not as apparent as that in the cisplatin group. Results suggested that Liushen Pil can inhibit the growth of the esophageal cancer xenografts. Liushen Pil can down-regulate the expression of vascular endothelial growth factor and reduce microvessel density, which is one of the tumor-inhibiting mechanism of Liushen Pil .

Objective To investigate the protective effect of allopurinol in kainic acid-induced epileptic rats and to explore new ideas and methods for the clinical treatment of epilepsy. Methods 120 Wistar rats were randomly divided into sham group, KA epilepsy group and allopurinol groups. Six rats of each group were randomly selected and were given electrodes into their left frontal and hippocampal regions. After injection, behavior changes were observed in all rates without electrodes. 24 h later, MDA level and SOD enzymatic activity of the left hippocampi were measured. One week later, the EEGs were recorded in rates with electrode, as well as total time of seizures /30 min and numbers of seizures / 30 min. Results Compared with the KA model group, latency period of the epilepsy in the allopurinol group was longer (P < 0.05) and the extent was lighter (P < 0.05); the MDA level was significantly lower (P < 0.01), the SOD enzymatic activity was significantly higher (P < 0.01). The total time of seizures / 30min and numbers of seizures / 30 min in allopurinol group reduced significantly (P < 0.01). Conclusion Allopurinol has potential antiepileptic and antioxidative activities in kainic acid-induced epileptic rats.

Objective To explore the expression of human sodium coupled neutral amino acid transporter 1 (SNAT1) in human glioma tissues and its relationship with clinical pathological parameters and prognosis. Methods Immu?nohistochemical and western blotting were used to detect SNAT1 expression in glioma tissue and tumor peripheral tissue from 89 cases of glioma patients including 55 cases of low grade gliomas (WHO I-II), and 34 cases of high grade gliomas (WHO grade III-IV).χ2 test and was used to analyze the relationship between expression and clinical pathological param?eters of SNAT1. Kaplan-Meier method was used to analyze the effect of different expression of SNAT1 on the prognosis of patients and to establish the Cox regression model. Results The expression of SNAT1 was significantly higher in gliomas than in tumor peripheral tissue (t=-9.803, P=0.001). The expression of SNAT1 was significantly higher in high pathologi?cal grade tissues than in low grade of glioma tissues (t=-6.682, P=0.003). SNAT1 expression was associated with tumor di?ameter and pathological grade (χ2=4.963, 8.527, P<0.05);Cox regression model showed that the tumor pathological grade and different SNAT1 protein expression were independent risk factors for the prognosis of patients with glioma. Conclu?sions The expression of SNAT1 protein is closely associated with the pathological grade of gliomas and the prognosis of the patients, which may be a new target to judge the biological characteristics and to evaluate the prognosis of gliomas.
