ABSTRACT
Objective:To investigate the effect of modified Shenling Baizhu San on the pathological changes and extracellular matrix (ECM) in rats with peritoneal fibrosis induced by peritoneal dialysate fluid (PDF) with different sugar concentration and its mechanism.Methods:Seventy male Sprague-Dawley (SD) rats were randomly divided into control group, different sugar content PDF model groups and corresponding traditional Chinese medicine intervention groups, with 10 rats in each group. Peritoneal fibrosis model was reproduced by intraperitoneal injection of 100 mL·kg -1·d -1 PDF containing 1.5%, 2.5% and 4.25% sugar once a day for 8 weeks. The rats in the control group were given the same amount of normal saline. The rats in the traditional Chinese medicine intervention groups were treated with gavage of 10 mL/kg of modified Shenling Baizhu San (containing 2.014 g crude drug per liter) immediately after modeling. The PDF model groups and the control group were given the same amount of normal saline by gavage. After 8 weeks, the peritoneal ultrafiltration volume of rats in each group was measured. The peritoneal tissues were collected and stained with hematoxylin-eosin (HE), and the structural changes and thickness of the parietal peritoneum were observed under a light microscope. After Masson staining, the deposition of collagen fibers was observed under a light microscope. Western blotting was used to detect the protein expressions of E-cadherin,?α-smooth muscle actin (α-SMA) and Vimentin, the main components of ECM in parietal peritoneum. The positive expressions of matrix metalloproteinase-9 (MMP-9), tissue inhibitor of metalloproteinase-1 (TIMP-1), and transforming growth factor-β1 (TGF-β1) were detected by immunohistochemical staining. Results:Compared with the control group, PDF with different sugar contents could induce peritoneal fibrosis in rats, and the degree of fibrosis was gradually aggravated with the increase of sugar content, which was manifested as peritoneal thickening, increased collagen fiber deposition, decreased peritoneal ultrafiltration volume, down-regulated expressions of E-cadherin and MMP-9 in peritoneal tissue, and up-regulated expressions of α-SMA, Vimentin, TIMP-1 and TGF-β1, and the pathological changes and ECM accumulation in peritoneal tissues were more serious in 4.25% PDF model group. After the intervention of modified Shenling Baizhu San, compared with the corresponding PDF model groups, the peritoneal fibrosis of rats was improved to varying degrees, and the effect of the 4.25% PDF+traditional Chinese medicine intervention group was more significant, the parietal peritoneum was significantly thinner (μm: 101.86±16.01 vs. 140.65±10.13, P < 0.05), collagen fiber deposition was significantly reduced, peritoneal ultrafiltration volume was significantly increased (mL: -0.01±3.45 vs. -3.53±1.84, P < 0.05), the expressions of E-cadherin and MMP-9 in peritoneal tissues were significantly up-regulated [E-cadherin protein (E-cadherin/β-actin): 0.84±0.08 vs. 0.28±0.05, MMP-9 ( A value): 0.60±0.15 vs. 0.37±0.01, both P < 0.05], and the expressions of α-SMA, Vimentin, TIMP-1 and TGF-β1 were significantly down-regulated [α-SMA protein (α-SMA/β-actin): 0.36±0.08 vs. 1.05±0.09, Vimentin protein (Vimentin/β-actin): 0.53±0.07 vs. 1.19±0.04, TIMP-1 ( A value): 0.49±0.06 vs. 0.87±0.02, TGF-β1 ( A value): 0.67±0.04 vs. 0.89±0.10, all P < 0.05]. Conclusions:The degree of peritoneal fibrosis gradually increased with the increase of PDF sugar content in rats. Modified Shenling Baizhu San can improve peritoneal fibrosis induced by PDF with different sugar contents in rats, and the mechanism is related to the changes in the expression of fibrosis markers and ECM accumulation.
ABSTRACT
The pathogenesis, diagnosis and management of glaucoma are complex and the population with glaucoma is huge in China now.With the development and popularization of cataract surgery, the visual disability and blindness caused by glaucoma are becoming more and more prominent.With the advantages of the combination of clinical pathway and public health in China, it is necessary to pay close attention to the following focuses of the prevention and control of glaucoma according to China's national conditions.(1)The awareness of glaucoma prevention and control should be strengthened, and the relevant screening technology and the construction of special team should be promoted to achieve the goal of early screening, early diagnosis and early treatment.(2)The diagnosis and treatment guidelines for glaucoma should be further well-established to promote the application of appropriate technologies in glaucoma diagnosis and treatment.In addition, glaucoma should be included in the chronic disease management system to accelerate the establishment and improvement of a three-level medical network system.(3)At the same time, the rehabilitation measurement for the patients with glaucomatous low vision should be reinforced to reduce the glaucomatous blindness rate.(4)The whole-process management for glaucoma patients should be enhanced, and nationwide popular science education should be well implemented.
ABSTRACT
Objective:To investigate the correlation between decline of intrinsic capacity and falls in the elderly, in order to provide a new method and basis for fall risk assessment.Methods:A total of 125 elderly inpatients were selected between March 2019 and December 2019 for the survey.The intrinsic capacity of elderly inpatients was evaluated, and the history of falls in the past year were obtained through interviewing.The impact of intrinsic capacity on the risk of falls was analyzed by using logistics regression analysis.Results:Of 125 elderly patients, 37 had experienced falls in the past year, with an incidence of 29.6%(37/125). A decline of intrinsic capacity in varying degrees was found in 92.0%(115/125)of elderly patients and the average score of decline was 2.2(1.0, 3.0). The more intrinsic capacity decreased, the greater the risk of falls( OR=2.425, 95% CI: 1.132-4.848, P=0.016). After taking demographics into consideration, age( OR=1.786, 95% CI: 1.034-2.023)and decline of intrinsic capacity( OR=2.425, 95% CI: 1.132-4.848)were independent risk factors for falls. Conclusions:Decline of intrinsic capacity is closely related to the occurrence of falls.The five-dimension framework of intrinsic capacity provides new ideas and directions for predicting the risk of falls.
ABSTRACT
The pathogenesis and clinical manifestations of glaucoma in children are quite complex and diverse.Because the visual function of childhood is in a developing stage, even the intraocular pressure is controlled well, the visual function of childhood glaucoma patients is often poor from ametropia and amblyopia.So the prognosis is unsatisfying.New diagnostic classification of childhood glaucoma of the World Glaucoma Association showed that, except for glaucoma associated with acquired conditions and secondary glaucoma following cataract surgery, ocular anterior segment dysplasia in tissue structure and genetic factors are involved in the pathogenesis to different degrees in other classifications of childhood glaucoma.Therefore, it is very important for researchers to actively carry out genetic evaluation for childhood glaucoma.Current research status of molecular genetics in childhood glaucoma is briefly described here to emphasize that the researchers should make full use of available disease resources in China to carry out the study of molecular genetics in the diagnosis and classification of childhood glaucoma, which can provide more evidences for the prevention and treatment of blindness in children and healthy birth policy.
ABSTRACT
Objective To investigate the clinical significance of biochemical markers in EBC and serum in patients with bronchial asthma and chronic obstructive pulmonary disease overlap syndrome(ACOS). Methods We selected Patients with chronic airway inflammatory diseases in our hospital,These patients underwent clinical trial after the stable phase,including 18 ACOS patients,22 asthma patients,24 COPD patients and 20 healthy non-smokers in the same period.8-isoPG and other inflammatory factors levels in EBC and serum were measured in the selected patients. A comparative analysis was performed. Results The levels of EBC 8-isoPG in the ACOS group were significantly higher than those in the healthy control group,The levels of serum and EBC 8-isoPG in the ACOS group were significantly higher than the asthma group and the COPD group(P < 0.05). The level of 8-isoPG in EBC was not related to age,smoking index,weight,and FEV1value(P>0.05).Conclusions Inflam-matory factors including 8-isoPG,are involved in chronic inflammation in lung tissues of patients with ACOS. 8-isoPG in EBC may have potential value in identifying ACOS from COPD and asthma as biomarkers and deserve further study.
ABSTRACT
Objective To investigate the effect of transitional care on postpartum negative mood for puerpera. Methods One hundred sixty eligible puerperas were recruited between January 2013 and October 2014. By order of hospitalization, participants were randomly assigned into two groups. The control group (80 cases) received routine care. The study group received transitional care which consisted of predischarge assessment, structured home visits and telephone follow-ups, psychological rehabilitation group activities, phone and internet consulting services within six months after discharge. Screenings of predischarge depression and anxiety symptoms of the study group were done by Hospital Anxiety and Depression Scale (HADS). Evaluations of depression and anxiety symptoms of two groups were done by Edinburgh postnatal depression scale (EPDS) and Self-Rating Anxiety Scale(SAS)on postpartum forty-two days and six months. Results There were no differences in demographics, maternal indicators and completion of follow-up between groups (P > 0.05). On postpartum forty-two days, the study group had significantly better depression and anxiety scores (P 0.05). On postpartum six months, the study group had significantly better depression and anxiety scores, less incidences of depression and anxiety than the control group (P group were 7.13±2.52 and 42.6±6.0, those of control group were 8.87±2.66 and 48.8±5.9. The incidences of depression and anxiety of study group were 6.4%(5/78)and 7.7%(6/78), those of control group were both 26.0%(20/77). Analysis of multiple linear regression suggested that age, education level and family income would affect transitional care intervention on postpartum depression. Conclusions This study established a nurse-led transitional care model which selected the gynecology and obstetrics professional nurse as advanced practice nurse. Results demonstrated that transitional care was effective on improving maternal postpartum depression and anxiety.

ABSTRACT
@#ObjectiveTo investigate the changes of non-linear dynamics characteristic of electroencephalogram (EEG) under three states (eyes closed, mental arithmetic with eyes closed and orientation test with eyes closed), and the application of non-linear dynamic analysis for cognitive function research.MethodsEEG was recorded in 30 healthy young volunteers at three stages. The correlation dimension (D2) and approximate entropy (ApEn) were calculated for all subjects.ResultsD2 and ApEn increased significantly during mental tasks as compared to the rest state with eyes closed (P<0.01). In different mental tasks, the complexity of mental functions and the regions involved in the cognitive task were different.ConclusionNon-linear analysis methods are appropriate for the study of cognitive functions and can help to understand the working mechanism of brain during mental activities.
ABSTRACT
@#ObjectiveTo study the prevalence rate of post-stroke depression (PSD) of the elderly in the community and analyze risk factors of them. MethodsThe elders of the age of 60 or over were sampled as subjects from a community. Zung (SDS) was used as screening instruments and Hamilton rating scale for depression (HRSD-24) as evaluating scales. The prevalence rate of PSD was surveyed. A structured questionnaire was used and physical examination was carried out. Risk factors measured included baseline information, daily habits, and history of main diseases (hypertension, coronary heart disease, diabetes mellitus, myocardial infarction, and so on). The relationship between risk factors and PSD was analyzed.ResultsThe prevalence of PSD was 9.5%. The risk factors for PSD were life quality and age. ConclusionPost-stroke depression disturbs elder's health and rehabilitation. The prevalence rate and harm of PSD are higher than depression without stroke.
