Objective:
To investigate the relationship between depressive symptoms and frailty among middle-aged and elderly populations, so as to provide insights into the early identification and prevention of frailty.
Methods:
Based on the 2018 database of China Health and Retirement Longitudinal Study (CHARLS), demographic information, lifestyle and self-rated health status were collected from people aged 50 years and older. Depression symptoms were evaluated using the Short Version of Center for Epidemiological Studies Depression Scales (CES-D-10), and the frailty status was evaluated using frailty index. The relationship between depressive symptoms and frailty among middle-aged and elderly populations were using a multivariable logistic regression model, and the dose-response relationship was analyzed using a restricted cubic spline model.
Results:
A total of 5 172 individuals were enrolled, including 2 495 males (48.24%) and 2 677 females (51.76%), with a median age of 63.00 (interquartile range, 12.00) years, a median CES-D-10 score of 7.00 (interquartile range, 9.00) scores. There were 1 560 participants (30.16%) detected with mild depressive symptoms, 360 participants (6.96%) detected with moderate to severe depressive symptoms. Multivariable logistic regression analysis showed that after adjusting for gender, age, educational level, marital status, smoking, alcohol consumption and self-rated health status, participants who had mild depressive symptoms (OR=4.226, 95%CI: 3.625-4.928) and moderate to severe depressive symptoms (OR=10.737, 95%CI: 8.259-13.958) had a higher risk of frailty. The restricted cubic spline model showed a nonlinear relationship between depressive symptoms and frailty among middle-aged and elderly populations. When the CES-D-10 scores were greater than 7, the risk of frailty increased with higher CES-D-10 scores.
Conclusion
The degree of depressive symptoms in middle-aged and elderly people is associated with frailty, and there is a nonlinear relationship between the two.

Objective To study the clinical manifestation and MRI feature of toxic encephalopathy after inhaling caffeine and sodium benzoate. Methods Three patients with toxic encephalopathy induced by inhaling caffeine and sodium benzoate were observed clinically and with MRI. Results The 3 patients were male. They all had definite addiction histories (the time of addiction for 3 years to 7 years ). There were special language and retropulsive dystonia besides the common characteristics of toxic encephalopathy:reaction retardation and disturbance of intelligence. MRI showed the change of generalized demyelination in bilateral symmetrical cerebral hemisphere, posterior limbs of internal capsule, corpus callosum, medial lemniscus, and cerebellum hemisphere dentate nucleus. The clinical symptoms of 3 patients were significantly improved 40 days after the adrenocortical steroid and neurotrophic treatment. The mild mood disorder remained in case 1. Conclusion Clinical manifestation and MRI of toxic encephalopathy after inhaling caffeine and sodium benzoate are known, so we could diagnose the patients of the disease in time.

Hormones and epigenetic characteristics in a patient with clinically diagnosed adrenal hypoplasia congenita (AHC) were analyzed. Results indicated that plasma ACTH increased, while cortisol, testosterone, LH and FSH decreased. LH, FSH and testosterone did not sufficiently respond to GnRH or hCG stimulation. Gene analysis indicated that C368F mutation was located in exon 1 of DAX-1 gene.

Aim To explore the protective effect of lo-ganin ( an active component in Cornus officinalis ) on podocyte injury induced by advanced glycation end products ( AGEs) and its possible mechanism. Meth-ods Mouse podocytes were cultured in vitro and di-vided into Normal group, model group ( AGEs group) , loganin group and aminoguanidine group ( set as posi-tive control) . After being incubated with loganin( final concentrations are 0. 1, 1, 10 μmol · L-1 ) for 1 h, podocytes were stimulated by AGEs of 100 mg · L-1 for 24 h. Then, the cell viability was measured by u-sing MTT method. Podocytes apoptosis was evaluated by Hoechst33342/PI staining and flow cytometry. Re-ceptors of advanced glycation end products ( RAGE ) ,desmin and apoptosis-related protein like Bax, Bcl-2, cleaved caspase-3 in podocytes were detected by Western blot. Results Loganin ameliorated podocyte injury induced by AGEs, down-regulated the expression of desmin and RAGE. Loganin also reduced the apoptotic rate of podocytes and decreased the ratio of Bax/ Bcl-2 and the expression of pro-apoptotic protein cleaved caspase-3 in podocytes. Conclusion Loganin could ameliorate podocyte injury, and its mechanism may be related to the decrease of the expression of RAGE and inhibition of the apoptotic pathway.

Objective To analyze the clinical characteristics of 1126 cases of malignant lymphoma in our hospital from 2005 to 2009. Methods Age, sex, pathological classification, onset locus and clinical staging of the malignant lymphoma were analyzed and summed up, based on the data of the malignant lymphoma patient information in hospital case database from 2005 to 2009 and excluded the cases as pathology was not sure and the repeated cases. Results A male:female ratio of malignant lymphoma in inpatient was 1.94:1. The majority of Hodgkin lymphoma (HL) manifested in 20-40 years old, mixed cellularity (64.16 %) and nodular sclerosis (29.48%) was most common. The majority of non-Hodgkin lymphoma (NHL) manifested in 50-70 years old, the most common pathological classifications were diffuse large B-cell lymphoma (53.31 %), extranode nasal-type NK/T cell lymphoma (7.35 %), mantle cell lymphoma (6.40 %), B chronic lymphocytic leukemia/small B-cell lymphoma (4.30 %), anaplastic large cell lymphoma (4.09 %), precursor T cell lymphoblastic leukemia/lymphoma (3.88 %), peripheral T cell lymphoma but not otherwise specified (3.46 %), angioimmunoblastic lymphoma(3.04 %), follicular lymphoma(2.94 %), Burkitt lymphoma (2.52 %). The onset locus of both HL and NHL most often involved lymph nodes of the cervical region. Conclusion The gender, age, pathological classification, onset locus and clinical staging of malignant lymphoma were different between HL and NHL.

Objective To investigate the effect of fluvastatin (FLV) on the expression of β1 integrin in puromycin aminonucleoside (PAN)-treated podocytes and its mechanism.Methods Cultured human podocytes were divided into PAN,different concentrations of fluvastatin (1 × 10-8 to 1 × 10-5 mol/L),SOD,H2O21 groups respectively.Expressions of β1 integrin and reactive oxygen species (ROS) in podocytes were detected by Western blotting and DCFHDA (2' 7'-Dichlorofluoresecein 3' 6'-diacetate) respectively.The viability of podocyte was determined by MTT colorimetry.Results PAN and H2O2 significantly decreased the expression of β1 integrin and increased the synthesis of ROS in podocytes (P<0.05respectively).Lower concentration fluvastatin or SOD treatment up-regulated β1 integrin and downregulated ROS of podocytes induced by PAN (P<0.05 respectively).MTT revealed that lower podocyte viability was found in higher concentration fluvastatin,PAN and H2O2 groups.Lower concentration fluvastatin and SOD could protect podocytes against PAN.Conclusion Fluvastatin attenuates the injury of podocyte induced by PAN and increases the expression of β1 integrin,whose mechanism may be associated with the inhibition of the ROS activity.
