Aim To study the effect of high salt diet during pregnancy on the development of renal vessels in offspring rats and its mechanism.Methods Natural pregnant Sprague-Dawley rats were randomly divided into high-salt group and control group.The pregnant rats in the high-salt group were given high-salt diet of 8% NaCl content , while the control group normal diet with 1% NaCl content.In both groups, pregnant rats were given normal drinking water.After delivery, all mothers returned to normal diet and all neonatal rats were breast-fed until one month old.The adult male off springs were used as experimental animals.The vessel tone of renal interlobar arteries and electrophysiological behavior of single vascular smooth muscle cells (VSMCs) were detected respectively.Results The contractile response of renal arteries to phenylephrine(Phe) in high-salt group was stronger than that in the control group(P<0.05).The effect of protein kinase C(PKC) non selective blocker GF109203X on Phe-induced contraction in two groups also showed significant difference(P<0.05).In electrophysiology experiments, Phe inhibited high-conductance Ca2+-activated K+ channel(BK channel) currents in renal arteriolar smooth muscle cells in two groups, and the inhibitory effect was more pronounced in high-salt offsprings (P<0.05).GF109203X could eliminate the response of Phe on BK currents in both groups(P>0.05).Conclusions High-salt diet during pregnancy could increase the sensitivity of renal interlobar arterial contractile response to Phe in adult male offsprings, which is associated with PKC-mediated BK channels pathway.Maternal high-salt diet during pregnancy may increase the risk of renal vascular diseases in adult offsprings.

Objective:To investigate the effects of self-help mindfulness-based stress reduction (MBSR) training on illness uncertainty andsleep quality in patients with atrial fibrillation (AF) after radiofrequency ablation. To provide the basis for improving the quality of life of these patients.Methods:This was a randam controlled Test. A convenient sampling method was used to select 90 patients with atrial fibrillation who underwent radiofrequency ablation in the First Peoples Hospital of Changzhou from January 2021 to December 2021. According to the random number table method. They were divided into the experimental group and the control group, with 45 cases in each group. The control group received routine nursing, and the observation group received home-based self-help MBSR training based on the routine nursing. Five Facet Mindfulness Questionnaire (FFMQ), Mishel Uncertainty in Illness Scale and the Pittsburgh Sleep Quality Index Scale (PSQI) were used to evaluate the scores of each scale before intervention, 8 weeks and 3 months after intervention.Results:A total of 42 cases were completed in the experimental group and 41 cases in the control group. Repeated measurement analysis of variance showed that there were interaction effect ( F interaction = 90.98, 46.27, 39.61, all P<0.01), time effect ( F time = 298.67, 179.06, 76.32, all P<0.01) and inter-group effect ( F intergroup = 19.88, 4.07, 18.70, all P<0.05) on mindfulness score, disease uncertainty score, total score of sleep quality and scores of all dimensionsin between the two groups. Simple effect analysis showed that scores of all scales in experimental groups were significantly better than those in control group after the intervention ( F values were 11.75 to 66.49, all P<0.01). Conclusion:Self-help MBSR training can improve the level of mindfulness, reduce the feeling of uncertainty and improve the quality of sleep in patients with atrial fibrillation after radiofrequency ablation.

Objective:To investigate the effect of hospital-community-family transitional rehabilitation care model on patients with brain trauma and explore an economic, effective, all-sided rehabilitation approach.Methods:A total of 82 in-patients with brain trauma were recruited from January 2018 to June 2019 in Shanghai Yang Zhi Rehabilitation Hospital (Shanghai Sunshine Rehabilitation Center). The participants were allocated into 2 groups based on randomized digital tables. Forty patients in the observation group received the hospital-community-family transitional rehabilitation care, and forty-two patients in the control group received routine rehabilitation care. All the participants completed assessments with the Fugl-Meyer Assessment Scale (FMA), the Barthel Index for the Activities of Daily Living (BI) and the Hamilton Anxiety Scale (HAMA) before the intervention, at discharge, 1 month, 4 months, 6 months and 10 months after discharge, respectively.Results:Before the intervention, no statistical significance was identified in the total scores of FMA, BI and HAMA between the two groups ( P>0.05). Compared to the control group, the total scores of FMA, BI and HAMA in the observation group were significantly improved at the discharge, 1 month, 4 months, 6 months and 10 months after discharge, respectively ( t values were -13.82 - 10.28, all P<0.05). Significant differences were observed in the level of FMA, BI and HAMA between the two groups across 6 time points ( Ftime×group=20.34, 18.34, 19.55, Ftime=183.24, 184.30, 179.09, Fgroup=28.86, 32.19, 26.63, all P<0.05). Conclusions:The hospital-community-family transitional rehabilitation care model which is based on medical consortium effectively improved traumatic brain-injured patients′motor function, the level of activities of daily living, and patients′anxiety. In addition, the model also improved the quality of medical services.

Objective:To explore the application effects of the Doctor-nurse-therapist integrated Model on the patients with brain injury in the rehabilitation period.Methods:A total of 60 patients with brain injury from January 2016 to October 2017 were selected as the control group underwent interventions based on traditional treatment model involving medical treatment, nursing and rehabilitation, and then 56 patients with brain injury from January 2018 to October 2019 were aselected as the experimental group followed Doctor-Nurse-Therapist integrated model for rehabilitation treatment. All subjects were recruited from inpatients hospitalized in the Forth Department of Neurological Rehabilitation, Shanghai Yangzhi Rehabilitation Hospital (Shanghai Sunshine Rehabilitation Center). The differences of motor function, activities of daily life (ADLs), anxiety and depression scores between the two groups were compared.Results:After 6 weeks of interventions, the scores of motor function were 80.27±18.20 and 67.32±19.71, and ADLs scores were 73.14±19.18 and 64.59±20.33 for the experimental group and the control group, respectively. The differences of the motor function and ADLs scores showed statistical significance between the experimental group and the control group ( t values were 3.491, 2.105, P<0.05). The anxiety and depression scores were 44.68±12.29 and 42.61±17.95 in the experimental group, while 52.25±12.95 and 50.84±18.14 in the control group, respectively. Statistical significance was found according to differences of anxiety and depression scores between the experimental group and the control group ( t values were 2.965,-2.236, P<0.05). Conclusions:Under the integrated model, doctors, nurses and therapists can evaluate, discuss, formulate and implement the flow scheme of the model, which can significantly improve the motor function and daily life ability of patients with brain injury in the rehabilitation period as well as anxiety, depression and the quality of medical services, and reduce the burden of family and society.

Ocular complications included corneal opacity, glaucoma, ametropia, strabismus, and chorioretinopathy. This review summarizes the mechanisms, clinical manifestations, specific ophthalmological examinations, and treatments for offering the ophthalmological knowledge to diagnose and begin treatment earlier.

OBJECTIVE：To investigate the correlation between CYP2C19 gene polymorphisms and antiplatelet reactivity of clopidogrel in Xinjiang Uygur patients with acute coronary syndrome （ACS）. METHODS ：Totally 90 Uygur patients with ACS who were admitted to the cardiovascular department of Xinjiang Kashi Second People ’s Hospital from Jan. 2018 to Jan. 2019 were selected as the study subjects. They were given anti-platelet therapy of asprin+clopidogrel ，and received the treatment continuously for one year after discharge. The platelet aggregation inhibition （DPAI）rate of the patients were determined ，and the response to clopidogrel was evaluated. PCR-fluorescence probe method was used to detect genotype of CYP2C19*2 and * 3，and PCR-direct sequencing method was used to detect genotype of * 17. Multivariate Logistic regression analysis was adopted to investigate the correlation of gene and non-gene factors with DPAI of patients. RESULTS ：Among 90 patients，there were 10 patients with clopidogrel resistance （CR）and 80 patients with non-CR. There were 58，28 and 4 patients with CYP2C19*2 G/G，G/A，A/A genotype，respectively；there were 88 and 2 patients with CYP2C19*3 G/G，G/A genotype ，respectively；there were 64 and 26 patients with CYP2C19*17 C/C，C/T genotype ，respectively；the genotype frequency of each genotype was consistent with Hardy-Weinberg equilibrium （P＞0.05）. After treatment ，DAPIs of patients with CYP2C19*2 G/A，A/A genotype were decreased significantly，while those of the patients with A/A genotype were significantly lower than patients with G/A genotype patients （P＜ 0.05）. DAPIs of patients with CYP2C19*17 C/T genotype were increased significantly ，compared with C/C genotype 2016D01C087） patients （P＜0.05）. There was no statistical significance in @fudan.edu.cn DAPIs between CYP2C19*3 G/A and A/A genotype patients （P＞0.05）. Multivariate Logistic regression analysis showed 85775264@qq.com that CYP2C19 gene pol ymorphism was independently related to DPAI in Xinjiang Uygur patients with ACS [OR ＝2.314，95％CI（1.569，3.144），P＝0.009]，while age ，gender，smoking and other non-gene factors were not related to DPAI （P＞0.05）. CONCLUSIONS ：CYP2C19 gene polymorphism is associated with antiplatelet reactivity of clopidogrel in Xinjiang Uygur patients with ACS. * 2 wild type patients may have higher DPAI ，while * 17 wild type patients may have lower DPAI.

We report a complete genomic sequence of rare isolates (minor genotype) of the SARS-CoV from SARS patients in Guangdong, China, where the first few cases emerged. The most striking discovery from the isolate is an extra 29-nucleotide sequence located at the nucleotide positions between 27,863 and 27,864 (referred to the complete sequence of BJ01) within an overlapped region composed of BGI-PUP5 (BGI-postulated uncharacterized protein 5) and BGI-PUP6 upstream of the N (nucleocapsid) protein. The discovery of this minor genotype, GD-Ins29, suggests a significant genetic event and differentiates it from the previously reported genotype, the dominant form among all sequenced SARS-CoV isolates. A 17-nt segment of this extra sequence is identical to a segment of the same size in two human mRNA sequences that may interfere with viral replication and transcription in the cytosol of the infected cells. It provides a new avenue for the exploration of the virus-host interaction in viral evolution, host pathogenesis, and vaccine development.
