Cerebrolysin is an aqueous mixture of amino acids extracted from porcine brain.Cerebrolysin, contains a variety of amino acids and low molecular weight peptides, are permeable to the blood-brain barrier and blood-ocular barrier and can directly act on neurons in the CNS.As amino acid-based neuroprotective reagents, cerebrolysin can improve the neuronal metabolism, promote synapse formation and induce neuronal differentiation, and thus elicit neuroprotective efffectagainst insults such as ischemia , neurotoxins and so on.Cerebrolysin is clinicly used to treat eye diseases such as traumatic eye damage, glaucoma, optic atrophy ect.This paper systematically summarizes the studies on preclinical and clinical application of cerebrolysin in ophthalmology.

Objective To evaluate the relationship and screening value of percentage of body fat (BF%) and waist height ratio (WHtR) for hyperlipidemia in physical examination people. Methods A total of 2 668 objects taking physical examination in Henan Province People′s Hospital from September to December 2014 were included in this study. Values of height, body mass index (BMI), waist circumference, body composition and blood lipid level were detected. The receiver oper?ating characteristic curve (ROC) was used to analyze the screening rate of WHtR and BF%on hyperlipidemia with sensitivi?ty, specific and area under the curve (AUC). After stratified by age, waist circumference and BMI, multivariable logistic re?gression analysis was used to investigate the association between hyperlipidemia risk, BF% and WHtR. Results The screening accuracy rate on hyperlipidemia was higher for BF%, AUC was 0.79 in both female and male people. Among wom?en with BMI<18.5 kg/m2 and 18.5~<24 kg/m2, the risk of hyperlipidemia was higher in superfatted group than that of normal group. There was no correlation between WHtR and hyperlipidemia. Among men older than 40 y or with abnormal waist cir?cumference (≥85 cm), the risk of hyperlipidemia was higher in superfatted group than that of normal group, but not associat?ed with WHtR. Conclusion The BF%is a better screening indicator for hyperlipidemia compared with that of WHtR and BMI. Women with BMI<18.5 kg/m2 and 18.5~<24 kg/m2 and men older than 40 y or with waist circumference over 85 cm are suggested to do body composition tests to improve screening accuracy for hyperlipidemia.

To investigate the effect of recombinant human growth hormone (rhGH) on JAK2-STAT3 pathway and the growth of gastric cancer cell lines at different GHR expression status, the eukaryotic expression vector targeting human GHR (pGPU6/GFP/Neo-shGHR and pGPU6/GFP/Neo-scramble) was constructed and transfected into MGC803 cells by Lipofectamine 2000. Stable expressive cell lines were obtained by G418 screening. The expression of GHR was analyzed by Western blotting. After being stimulated with rhGH, cell growth was detected by MTT assay. Cell cycle and apoptosis were examined by flow cytometry. The components of JAK2/STAT3 signaling pathway were detected by Western blotting. There is no significant difference of GHR expression between MGC803 and pGPU6/GFP/Neo-scramble-transfected cells (named as MGC803-NC) (P > 0.05). Compared with MGC803, the GHR expression in pGPU6/GFP/Neo-shGHR-transfected cells (named as MGC803-shGHR) decreased significantly (protein decreased 50%). The cells were treated with rhGH at 0, 150 and 300 ng x mL(-1), the growth rate of MGC803 and MGC803-NC increased significantly, PI and the number of G2/M phase cells all increased significantly, and apoptosis decreased significantly. Western blotting revealed that the expression of pJAK2 and pSTAT3 was up-regulated after being treated with rhGH in MGC803 and MGC803-NC cells. In contrast, similar change was not observed in MGC803-shGHR cells. Knockdown of GHR gene may decrease the sensitivity of gastric cancer cells to rhGH, and down-regulating of components of the expression of JAK2/STAT3 signaling pathway may be the potential mechanisms.

Objective To explore the effect of hospital-community-family integrated care on the physical and mental function of discharged stroke patients. Methods Sixty stroke patients discharged from the third people′s hospital of Bengbu were recruited from January 1, 2014 to April 30, 2015. The patients were divided into intervention group and control group by random number table, and 30 patients in each group. Rehabilitated nursing intervention including feeding, language, physical and psychological and psychological trainings were conducted in intervention group, while participants in control group only received routing nursing service. Then, the Barthel index scores, Fugl-Meyer motor function scores and Hanmilton Depression Scale (HAMD) scores were assessed in both two groups pre-intervention and six months after intervention. Results Intervened before and 6 months after the intervention group of patients with Barthel index score respectively (44.17 ± 11.21) points, (72.47 ± 15.36) points, Fugl-Meyer motor function scores were respectively (43.47±16.22) points, (62.39 ±15.41) points, HAMD scores were (26.81 ± 8.24) points, (17.42 ± 6.29). The difference was statistically significant (t=8.16, 4.64, 4.97, P <0.01). In contrast, the control group of patients with Barthel index score changes showed statistical significance (t=1.94, P=0.03), HAMD score also had differences (t=1.86, P=0.04) and the change was far less than the intervention group. Between the two groups after the intervention compared with Barthel index score, Fugl-Meyer motor function score and HAMD also had statistical significance (t=5.81, 3.55, 2.35, P = 0.00). Conclusions The rehabilitated nursing intervention has evident effects onliving environment,daily life, physical and mental function in discharged stroke patients, and the intervention approaches we used have certain clinical practice value.

Objective:To explore the relationship among internet / reality alienation, irrational beliefs and depression in medical college students.Methods:In October 2021, a total of 501 students from five medical colleges in Shandong were selected by the convenient sampling method.All the participants were assessed by the internet alienation scale, general alienation scale, irrational beliefs scale and self rating depression scale.SPSS 24.0 software was used for descriptive analysis, correlation analysis, and AMOS 21.0 software was used to conduct structural equation modeling and Bootstrap mediated effect test.Results:The scores of internet/reality alienation, irrational beliefs and depression were 3.12±1.35, 2.04±0.57, 2.72±0.72, 2.07±0.42, respectively.There was a statistically significant positive correlation among internet/reality alienation, irrational beliefs and depression( r=0.56-0.64, P<0.01). Structural equation modeling showed that the mediating effect of irrational beliefs between internet alienation and depression was 0.05(95% CI=0.01-0.11). The mediating effect of irrational beliefs between reality alienation and depression was 0.16(95% CI=0.06-0.30). Conclusion:Internet/ reality alienation can indirectly effect depression of medical college students through the mediation of irrational beliefs.

Objective To analyze the scores of National Institutes of Health stroke scale(NIHSS),geriatric nutritional risk index(GNRI),motor function in dependence measure(MFIM)and the risk of stroke-related pneumonia(SAP).Methods Patients with stroke admitted from November,2021 to May,2022 were included.The scores of NIHSS,GNRI and MFIM at admission were collected,and they were divided into non-SAP group(n=232)and SAP group(n=86)according to whether pneumonia occurred within one week after stroke.According to the receiver operating characteristic(ROC)curve,the predictive ability of each score to SAP was evaluated,and each score was grouped according to the best cut-off point.logistic regression model and restricted cubic spline were used to analyze the relationship between each score and SAP.Results A total of 318 stroke patients were enrolled in the study including 86 in SAP group and 232 in non-SAP group.Logistic regression shows that,levels of NIHSS score(OR=32.783,95％CI:16.366～65.671,P<0.001),MFIM score(OR=0.052,95％CI:0.027～0.100,P<0.001)and GNRI score(OR=0.262,95％CI:0.144～0.476,P<0.001)were associated with SAP.Restricted cubic spline analysis shows that,there was a nonlinear dose-response relationship between SAP risk and NIHSS score(P-general trend<0.001,P-nonlinear=0.002),GNRI score(P-general trend<0.001,P-nonlinear<0.001).Conclusion NIHSS,MFIM,and GNRI scores are associated with the risk of SAP in stroke patients,and some of them have nonlinear relationships.

Objective:To screen high-risk population of chronic obstructive pulmonary disease (COPD) and to analyze the risk factors in Haicang District of Xiamen City.Methods:A questionnaire survey was conducted from February 2023 to May 2023 among residents who visited or underwent physical examinations at five community health service centers in Haicang District of Xiamen City selected by cluster sampling method. The self-designed general information questionnaire, COPD population screening questionnaire (COPD-PS) and COPD screening questionnaires (COPD-SQ) were applied in the survey. Individuals with COPD-PS scale>5 or COPD-SQ scale>16 were defined as COPD high-risk group. The association of COPD risk with gender, age, smoking, family history of COPD, history of tuberculosis, history of COVID-19 infection, and using coal/woodstove for cooking or heating was analyzed with chi-square test and binary logistic regression analysis.Results:A total of 4 260 questionnaires were distributed and 4 221 valid questionnaires were collected with a recovery rate of 99.6%. Among all respondents there were 1 904 males (45.11%) and 2 317 females (54.89%); and 217 individuals aged 40-<50 (5.14%), 434 aged 50-<60 (10.28%), 2 194 aged 60-<70 (51.98%), 1 302 aged 70-<80 (30.85%) and 74 aged≥80 (1.76%). The results showed that there were 269 respondents (6.4%) scored≥5 on the COPD-PS scale, 534 residents (12.7%) scored≥16 on the COPD-SQ scale, 646 (15.3%) scored≥5 on the COPD-PS scale or≥16 on the COPD-SQ scale. Male gender ( OR=2.592, 95% CI:2.135-3.146), second-hand smoke exposure ( OR=3.763, 95% CI:2.944-4.810), frequently catching cold before the age of 14 ( OR=3.804, 95% CI:2.927-4.944), history of tuberculosis ( OR=2.575, 95% CI:1.224-5.418), hypertension ( OR=1.547, 95% CI:1.277-1.875), and diabetes ( OR=1.791, 95% CI:1.027-3.121) were independently associated with the high-risk of COPD, while the history of COVID-19 ( OR=0.583, 95% CI:0.476-0.714) was a protective factor for COPD risk. Conclusion:Males, exposure to second-hand smoke, frequently catching cold before the age of 14, history of tuberculosis, hypertension, and diabetes will increase the risk of COPD, while the history of COVID-19 is a protective factor.

Objective:To discuss the protective effect of velvet antler peptide(VAP)in the osteoporosis(OP)model rats,and to clarify the possible mechanism.Methods:Sixty 12-week-old SD rats were randomly divided into control group,model group,positive drug group(treated with 1 mg·kg-1·d-1 of alendronate sodium by gavage),low dose of VAP group(treated with 100 mg·kg-1·d-1 VAP),medium dose of VAP group(treated with 200 mg·kg-1·d-1 VAP),and high dose of VAP group(treated with 300 mg·kg-1·d-1 VAP),and there were ten rats in each group.Except for control group,the rats in the other groups were injected with dexamethasone(2 mg·kg-1)to replicate the OP rat model,while the rats in control group were injected with the equivalent volume of saline twice a week for 11 consecutive weeks.Dual-energy X-ray absorptiometry was used to detect the bone mineral density(BMD)of femur tissue of the rats in various groups;enzyme-linked immunosorbent assay(ELISA)method was used to detect the levels of serum calcium(Ca2+),phosphate(P),osteoprotegerin(OPG),alkaline phosphatase(ALP),and osteocalcin(OCN)in serum of the rats in various groups;biochemical method was used to detect the malondialdehyde(MDA)level and superoxide dismutase(SOD)activity in serum of the rats in various groups;HE staining was used to observe the pathomorphology of bone tissue of the rats in various groups;Western blotting method was used to detect the expression levels of silent information regulator 1(SIRT1),catalase(CAT),Runt-related transcription factor 2(RUNX2),and forkhead box protein O1(FOXO1)proteins in bone tissue of the rats in various groups.Results:Compared with control group,the BMD of femoral tissue of the rats in model group was decreased(P<0.05);compared with model group,the BMD of femur tissue of the rats in positive drug group,medium dose of VAP group,and high dose of VAP group were increased(P<0.05 or P<0.01).Compared with control group,the levels of Ca2+,P,OPG,and SOD activities in serum of the rats in model group were decreased(P<0.05),and the levels of ALP,OCN,and MDA were increased(P<0.05);compared with model group,the level of OPG in serum of the rats in low dose of VAP group was significantly increased(P<0.05),the levels of Ca2+,P,OPG,and activities of SOD in serum of the rats in positive drug group,medium dose of VAP group,and high dose of VAP group were significantly increased(P<0.05 or P<0.01),and the levels of ALP,OCN,and MDA in serum of the rats in positive drug group and different doses of VAP groups were decreased(P<0.05 or P<0.01).The HE staining results showed that compared with control group,the rats in model group had fewer bone cells and disordered arrangements in the bone tissue,thinner bone trabeculae with large fractures,and an expanded marrow cavity;compared with model group,the rats in positive drug group,medium dose of VAP group,and high dose of VAP group had thicker bone trabeculae arranged more tightly.The Western blotting results showed that compared with control group,the expression levels of SIRT1,CAT,RUNX2,and FOXO1 proteins in bone tissue of the rats in model group were decreased(P<0.05);compared with model group,the expression levels of SIRT1,CAT,RUNX2,and FOXO1 proteins in bone tissue of the rats in positive drug group,medium dose of VAP group,and high dose of VAP group were significantly increased(P<0.05 or P<0.01).Conclusion:VAP has the protective effect against OP in the rats,and its mechanism may be related to mediating the antioxidant stress action through the SIRT1/FOXO1 signaling pathway.
