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 investigate if acupuncture has an inhibitory effect on fatty toxicity and its possible mechanism. Methods: Thirty-four patients with simple obesity were clinically treated with acupuncture for 3 courses. Before and after treatment, body mass index(BMI) and fat percentage(F%) were determined, and serum insulin and adiponectin were measured by enzyme linked immunoassay, blood lipid and sugar by biochemical colorimetry and eight kinds of free fatty acids(FFAs) by high performance liquid chromatography. Twenty normal persons were selected as a control. Results:The total efficacy rate was 88.2%. Acupuncture could increase the decreased insulin sensitivity index(ISI) in the patients(t=-5.103, P=0.000). The correlation of a decrease in F% with an increase in unsaturated fatty acid after acupuncture was of significance(r=0.402, P=0.019) and its correlation with an increase in the ratio between unsaturated fatty acid and saturated fatty acid was also of significance(r=0.348, P=0.044). The correlation between increases in high density lipoprotein and in eicosapentaenoic acid was of significance(r=0.352, P＝0.041). The correlation between a decrease in BMI and an increase in high density lipoprotein was of significance(r=0.357, P=0.038). Adiponectin level significantly rose after acupuncture (compared with pre-treatment, P=0.000). The correlation between a decrease in FFAs and an increase in adiponectin was of significance(r=-0.349, P=0.043). Conclusion: Acupuncture can lower the levels of free fatty acids in the patients and increase their sensitivity to insulin to inhibit the fatty toxicity. The inhibitory effect of acupuncture on fatty toxicity is somewhat related to a rise in adiponectin level.

Nerve growth factor (NGF) promotes neuronal survival and differentiation and stimulates neurite outgrowth. NGF is synthesized as a precursor-proNGF in vivo. In this paper, a pET-proNGF prokaryocyte expression vector was constructed and transformed into E. coli BL21(DE3)pLysS. The proNGF was expressed in the form of non-active aggregated monomer in E. coli after induction with IPTG. SDS-PAGE revealed the proNGF expression product had a Mr.30.2 kD. Western blotting analysis showed that the protein had good antigenicity. Fusion protein was successfully purified by Ni2+-NTA affinity chromatography and cleaved by Enterokinase and 13.1 mg proNGF was obtained from 100 mL cell culture in a typical experiment. The protein was dialyzed in a redox system containing reduced and oxidized glutathione. RP-HPLC was used to analysis the result of the refolding. The refolded proNGF protein can induce neurite outgrowth of PC12 cells, which indicated that pro-form of NGF we obtained had biological activity.

PURPOSE: The aim of this study was to evaluate the effects of reflective trainings for nursing students on their critical thinking disposition. METHODS: A total of 157 senior undergraduate nursing students sampled from Hainan Medical University in China participated in this study in 2014. They were randomly divided into experimental and control groups. The experimental group students were provided the reflective training during their entire 12-month clinical internship, whereas students in the control group were requested to keep their reflective diaries but without a formal training. Before and after the intervention, nursing students' critical thinking disposition was rated using the Chinese version of Critical Thinking Disposition Inventory (CTDI-CV). RESULTS: Before the start of the intervention, the critical thinking disposition scores of the two groups had no significant differences. At the end of the intervention, it was found that the experimental students performed better in each subscale of CTDI-CV. These include the search for truth, open mind, analytical ability, systematic ability, critical thinking, self-confidence, curiosity, and cognitive maturity. By summing the scores of all categories, the results showed that the experimental group had a significantly higher total score than that of the control group (p ≤ .044). Evaluating the score difference in each function indicated that there was a range of improvements on the critical thinking disposition because of the reflective training intervention. CONCLUSION: Reflective training during the internship period improves nursing students' disposition of critical thinking and promotes their readiness for their clinical practices in the rapidly increasing demands of the healthcare field.

The clinical data of 14 patients with niacin deficiency diagnosed and treated in Department of Dermatology, Affiliated Hospital of Jining Medical College from 2012 to 2021 were retrospectively analyzed. There were 11 males and 3 females aged 26-65 years. The etiological factors were alcoholism in 8 cases, gastrointestinal disease in 3 cases, medication history in 1 case, and unknown etiology in 2 cases.Patients had typical skin lesions, 1 case also had both digestive system and nervous system symptoms, and 3 cases had combined digestive system symptoms and 2 cases had neurological symptoms. All patients were systematically treated with oral nicotinamide and vitamin B complex, and also with topical drugs; and they all improved after 14-52 days of treatment. During regular follow-up, 2 cases of alcoholics and 1 case with diarrhea had recurrence. It is suggested that the typical clinical triad of niacin deficiency is uncommon, and the diagnosis is based on the medical history, clinical manifestations and relevant laboratory test, and the treatment with nicotinamide and vitamin B complex is usually effective; alcoholism is the main cause in male patients and is prone to recurrence.

Objective To reveal the mechanisms of immunological infertility,the method of coimmunoprecipitation(CO-IP) and liquid chromatogram mass/mass (LC-MS/MS) was used to screen sperm membrane proteins which interacting with antisperm antibodies (ASA).Methods This study was designed as a case-control.The disease group including 56 serum samples from 521 cryptogenic infertile patients were screened ASA positive by ELISA and conformed with mixed antiglobulin reaction(MAR).The controls were 31 serum samples which ASA is negative and already possessed healthy offspring.All subjects were enrolled from September 2015 to December 2015 in China PLA General Hospital.Spermatozoa samples from 48donors with normal sperm parameters were from January 2016 to April 2016 in China PLA General Hospital.The purified human sperm membrane proteins were then mixed with serum from disease group (positive for ASA) and control group (not containing ASA).The binding proteins of antisperm antibodies were enriched using CO-IP assay.The immunoprecipitates were separated on sodium dodecyl sulfate-polyactylamide gel (SDS-PAGE),then the binding proteins were cut from the gel and analyzed by LC-MS/MS after the enzymolysis.These proteins could bc idcntified as definition,biological function (s) and subccllular localization with Uniprot database.Results The serum samples from infertile persons (39 females and 17males) were screened ASA positive by ELISA and conformed with MAR.The healthy controls (17 females and 14 males) were ASA-negative in ELISA.Forty proteins that interact with ASA were obtained from the study and these could be divided into three groups:11 antigens detected by control serum samples only,14antigens recognised by both infertile patients and control sera,and 15 antigens specific for patients with ASA.These 15 proteins are Sperm Cation channcl protein 1,Sperm Cation channel protein 3,Sperm Cation channel protein 4,Sperm associated antigen 9,Apolipoprotein A-I,Dynein heavy chain 14,Cylicin-2,Izumo sperm-egg fusion protein 4,Thioredoxin domain-containing protein 2,IQ domain-containing protein H,IQ domain-containing protein F1,Spermatogenesis-associated protein 5,Spermatogenesis-associated protein 5-like protein 1,Sperm acrosome membrane-associated protein 1,E3 ubiquitin-protein ligase RNF 114.Conclusion Fifteen proteins discovered with CO-IP technology and LC-MS/MS analysis could be referred as male immunoinfertility-related antigens and they may hold the great importance in revealing the secret of immunological infertility.

Objective:The aims of the study were to investigate the relationship among atherogenic index of plasma (AIP) and inflammatory adipocytokines with the severity of coronary artery calcification (CAC) score in coronary artery disease (CAD). And then we analyzed the diagnostic value of the new markers on CAC.Methods:A total of 241 patients with CAD diagnosed by coronary CT angiography (CTA) and coronary angiography in Baoding First Central Hospital from June 2019 to June 2020 were retrospectively enrolled. According to the presence of calcification in coronary CTA, they were divided into CAC group ( n=63) and non-CAC group ( n=178). The clinical data of the patients were collected, and the levels of serum inflammatory factors were measured by enzyme-linked immunosorbent assay (ELISA). The correlation between CAC score and AIP and inflammatory cytokines was analyzed. The diagnostic value of AIP and inflammatory factors in the formation of CAC in patients with CAD. Results:The levels of AIP, serum osteoprotegerin (OPG) and oligomeric matrix protein (COMP) in CAC group were higher than those in non-CAC group, while the levels of serum fibroblast growth factor 21 (FGF21) were lower than those in non-CAC group, with statistically significant difference (all P<0.01). Correlation analysis showed that CAC score of CAD patients was positively correlated with AIP, OPG and COMP ( r=0.581, 0.451, 0.326, P<0.05), and negatively correlated with FGF21 ( r=-0.294, P<0.05). Receiver operating characteristic (ROC) curve analysis showed that AIP, OPG, COMP and FGF21 had diagnostic value for CAC in CAD patients (all P<0.05). AIP>0.387, OPG>5.150 ng/ml, FGF21>136.35 pg/ml, COMP>733.16 ng/ml were independent factors affecting the formation of CAC (all P<0.05). Conclusions:The increase of AIP and the change of inflammatory factors can be used as markers for the diagnosis of CAC formation in CAD patients.
