Objective To study the expression and regulation of aquapofins (AQP) in cystic epithelial cells of jck mice with polycystic kidney disease. Methods Localization and regulation of AQP1, AQP2, AQP3 and AQP4 protein were analyzed by using the immunofluorescence and Western blotting. Results Kidneys of jck homozygous mice were 4 folds larger than those of litter matched wild-type mice. There were multiple cysts and fibrosis in the renal tissue of jck mice. The epithelial cells in cysts were flat in shape. Blood urea level in jck mice was (42.6 ± 6.7) mmol/L, which was 5 folds higher than that in wild-type mice [(8.4±1.9) mmol/L] (P<0.01). Immunofluorescence analysis showed that AQP1 was expressed in the apical and hasolatend membranes of epithelial cells in proximal tubules, as well as in the thin descending limb of Henle and endothelial cells of descending vasa recta. There was no AQP1 expression in epithelial cells of cysts. AQP2 was expressed in the apical membranes of collecting ducts and renal cysts. AQP3 and AQP4 were expressed in basolateral membranes of collecting duct and renal cystic epithelial cells of jck mice. Western blot analysis showed the same protein sizes of AQP1, AQP2, AQP3 and AQP4 in both jck and wild-type kidneys. However, AQP1 expression was down-regulated in jck kidneys (P<0.01). Conclusion The renal cystic epithelia expresses AQP2, AQP3 and AQP4, which indicates that epithelial cells in renal cysts are derived from renal collecting ducts in jck mice and aquaporins may play an important role in renal cyst development.

Blood glucose level responses to different diets were examined in 12 healthy man. The test breakfasts consist of different proportion of protein and carbohydrate. Three kinds of test breakfast were fed respectively for each person. Blood glucose were measured before and 1, 2 and 4 hr after breakfast. The results indicated that high-CHO diet maintained higher level of blood glucose than other diets in 1-2 hr after breakfast. However the blood glucose level began dropping from 2 hr and dropped below fasting level at 4 hr after breakfast. The high-protein diet resulted in decreasing of blood glucose level in 1-2 hr after breakfast. The blood glucose level then increased continuously until 4 hr after breakfast.The results in this experiment showed that adjustment of the proportion of carbohydrate and protein in diets could maintain the blood glucose to a higher and stable level.

Objective To evaluate the significance of sonographically detected thyroid calcification in the diagnosis of thyroid carcinoma.Methods Five hundred and twenty-two patients with thyroid disease,including 119 with thyroid cancer,were included in the study.Each patient underwent preoperative,highresolution sonography to evaluate the thyroid gland for the presence of calcification.Calcifications were classified:type Ⅰ,microcalcification;type Ⅱ,coarse calcification;type Ⅲ,annular or"egg-shell"calcification;typeⅣ,calcified nodules within a cyst.Results The incidence of calcification and microcalcification was significantly higher in thyroid cancer than in benign nodules(P＜0.001).The appearance of microcalcifications was highly specific for malignancy with a sonographic specificity of 88%.The sensitivity was 60%,and the odds ratio(0R)was 11.28.The incidence of calcifications of type Ⅱ and type Ⅲ did not differ significantly between the benign and malignant groups.Calcifications of type Ⅳ were showed totally in benign groups.Patients younger than 45 years with calcified nodules constituted a highrisk group,with a OR of 11.33 versus 2.96 in patients older than 45 years with calcified nodules.In the group of solitary thyroid nodules,the incidence of cancer in the calcified nodules was higher than in the nodules without calcifications,with a OR of 20.48.Conclusions The detection of thyroid calcifications by sonography is diagnostically valuable,especially in eases involving a solitary nodule or a young person.The presence of calcifications in these cases should raise the suspicion of malignancy,especially microcalcification.

Background and objective Apolipoprotein E is a constituent of lipoproteins with considerable variation due to cysteine-arginine exchanges. We investigated the relationship between apo E gene polymorphism and the occurrence of coronary artery disease(CAD) in the older population of northern China. Methods The distribution of the HhaI polymorphisms of the apolipoprotein E gene was determined among 55 patients with CAD (CAD group), which was compared with that of 36 elderly subjects without CAD(control group). Results Genotype distributions at both sites (apo E gene 112-bp and 158-bp sites ) were different between the CAD and control groups. The CAD group had lower apolipoprotein Eε2frequencies than the control group (P＜0.05). Conclusion Individuals with apolipoprotein Eε2are likely to have a reduced risk of developing coronary artery disease as demonstrated by elderly subjects in Northern China.

Objective To explore the effect of emergency nursing combined with predictive rehabilitation nursing on rehabilitation and prognosis of patients with acute stroke. Methods One hundred and thirty patients with acute stroke admitted to Zhejiang Hospital from June 2017 to December 2018 were enrolled, and they were divided into an emergency nursing group and a combined nursing group according to different nursing methods, 65 cases in each group. The emergency nursing group was given emergency nursing; and the combined nursing group was given emergency nursing combined with predictive rehabilitation nursing. After 2 weeks, the clinical efficacy was evaluated. The neurological function, motor ability, cognitive function, activities of daily living, clinical efficacy and the incidence of complications were observed in the two groups. Results After treatment, the scores of American National Institutes of Health Stroke Scale (NIHSS) in two groups was significantly lower than that before treatment, the scores of simple Fugl-Meyer motor function (FMA) and simple intelligent mental state examination scale (MMSE), Barthel index (BI) were obviously higher than those before treatment, and the changes of the above indexes in the combined nursing group were more significant than those in the emergency nursing group after treatment (NIHSS score: 13.68±4.01 vs. 19.47±3.82, FMA score: 31.65±4.11 vs. 26.47±4.53, MMSE: 25.34±3.71 vs. 20.07±3.08, BI: 54.68±7.01 vs. 47.37±6.51), the differences were statistically significant (all P < 0.05). The total effective rate of the combined nursing group was significantly higher than that of the emergency nursing group [90.77% (59/65) vs. 75.39% (49/65), P < 0.05], and the incidence of complications in the combined nursing group was obviously lower than that in the emergency nursing group [21.51% (14/65) vs. 40.00% (26/65), P < 0.05]. Conclusion The emergency nursing combined with predictive rehabilitation nursing has good clinical effect on patients with acute stroke, it can effectively elevate the neurological function, motor ability, cognitive function and daily living ability, improve blood lipid and coagulation function indicators, reduce the incidence of complications, facilitate rehabilitation and improve prognosis.

OBJECTIVE: To evaluate the efficacy and safety of the sublingual immunotherapy with dermatophagoides farinae drops on patients with allergic rhinitis. METHOD: One hundred and twelve cases were collected from adult patients with dust-mite allergic rhinitis of our hospital who could adhere to treatment and regular follow-up. These patients were randomly allocated to receive either sublingual immunotherapy (SLIT group, n = 56) or medical treatment (Control group, n = 56). To evaluate the clinical efficacy by side effects which were registered, symptom and medication scores which were assessed and rhinoconjunctivitis quality of life questionnaire (RQLQ) which was completed in the baseline and two years after treatment. RESULT: Dropouts after the 2 years' treatment were 5 of SLIT group and 4 of Control group respectively. SLIT group induced the significant reductions on both the symptom scores (7.81 ± 3.14 to 3.89 ± 2.01, P < 0.0 1) and the medication scores (2.86 ± 0.75 to 0.44 ± 0.06, P < 0.01). Meanwhile, Control group induced the reductions on both the symptom scores (8.01 ± 3.32 to 5.20 ± 2.43) and the medication scores (2.95 ± 0.80 to 1.75 ± 0.40). There were significant differences (P< 0. 01) in symptom and medication scores between the two groups after 2-year treatment. The patients in SLIT group had fewer symptoms and lower intake of medication. There were statistically significant differences in RQLQ between SLIT group [19 (15,22)] and Control group [36 (26,47)] after two years treatment (Z = -5. 21, P < 0.01). SLIT group also had significant improvement in RQLQ (Z = -6.10, P < 0.01) between before and after the treatment. There were 4 patients who showed adverse reactions in SLIT group (3 occurred in increment period, and 1 occurred in the maintenance period). The incidence of adverse reactions was 7.14%. No severe systemic side effects were registered. CONCLUSION SLIT with standardized dermatophagoides farinae drops in China is safe and effective to patients with allergic rhinitis.

Objective To investigate the association between arterial compliance and fundus oculi arteriosclerosis in elderly people. Methods A total of 73 elderly subjects,including 61 elderly patients with fundus oculi arteriosclerosis and 12 healthy volunteers were recruited into the study.Capacitive arterial compliance(C1)and oscillatory arterial compliance(C2)were measured by DO2020 Cardiovascular Profiling Instrument.Moreover,fundus photographs were measured using Canon figure fundus camera. Results There were significant differences in systolic blood pressure(SBP),diastolic blood pressure(DBP),mean artery pressure,pulse pressure,capacitive arterial compliance (C1),and oscillatory arterial compliance(C2)between patients with fundus oculi arteriosclerosis and healthy volunteers(all P<0.05).In multiple regression analysis,the grade of fundus oculi arteriosclerosis was significantly correlated with SBP,DBP,mean artery pressure and pulse pressure (r=0.357,0.261,0.342,0.280,all P<0.05).Moreover,there were significant correlations between the grade of fundus oculi arteriosclerosis and Cl(r=-0.281,P<:0.05),and C2(r=-0.308,P<0.01). Conclusions These findings underscore the efficacy of C1 and C2 in identifying patients with fundus oculi arteriosclerosis.

Grid management plays an important role in improving the efficiency of social service management. The authors explored the establishment of a nosocomial infection grid management model and implemented it at a tertiary general hospital in Shanghai. χ2 test results showed that since the hospital fully implemented the grid management model in early 2016, the number of hospital infections, surgical site infections, type I surgical incision infections, and ventilator-related pneumonia had shown a downward trend year by year. The number of inspections before the use of antibacterial drugs, the number of blood cultures submitted for fever patients, and the timing of hand hygiene compliance showed an increasing trend year by year( P<0.05), and the management of nosocomial infection was more effective than the previous period. The application of grid management model required establishment of grid organization structure, control of key links, implementation of the special personnel responsibility, formulation of a performance evaluation system, and implementation of incentive measures. The grid management model can significantly reduce the risk of hospital infection, improve the efficiency of hospital infection management, and was valuable to be applicated and promoted in medical institutions.

Objective:To study the protective effect and mechanism of paeoniflorin (pae) on myocardial injury in septic rats.Methods:Sprague-Dawley (SD) rats were randomly divided into 4 groups with 10 rats in each group. Rats were intraperitoneally injected with 1.4 ml normal saline and 1.4 ml 5% dimethyl sulfoxide (DMSO)solution independently in control group and DMSO group. Rats were intraperitoneally injected with 1.4 ml normal saline and 1.4 ml pae independently, then with 0.1 ml lipopolysaccharide (LPS) 1 hour later in sepsis group and pae group. Enzyme linked immunosorbent assay (ELISA) was used to detect serum cardiac troponin I (cTnI) levels and myocardial tissue tumor necrosis factor alpha (TNFα), interleukin(IL)-6, IL-1β, chemokine (C-X-C motif) ligand 1 (CXCL1), chemokine (C-X-C motif) ligand 2 (CXCL2), vascular cell adhesion molecule 1 (VCAM-1) levels. Evans blue (EB) method was used to detect the EB content of myocardial tissue. HE staining method was used to observe the pathological changes, real-time quantitative polymerase chain reaction (RT-qPCR) to detect mRNA expression levels of the above molecules, and Western-blot to detect vascular endothelium-cadherin (VE-cadherin), phosphorylated p38 mitogen-activated protein kinase (P-p38MAPK), phosphorylated Src protein (P-Src), Ras-Related C3 Botulinum Toxin Substrate 1 (Rac1) levels.Results:Compared with control group, cTnI level and the EB content in sepsis group increased significantly, and the myocardial inflammatory cell infiltration was obvious. The cTnI level and EB content in pae group were significantly reduced, and myocardial inflammatory cell infiltration was reduced [cTnI: (227.7±15.9)pg/ml vs. (312.9±17.9)pg/ml;EB: (13.2±2.3)μg/g vs. (23.8±2.9)μg/g; P<0.05]. Compared with control group, the levels of TNFα, IL-6, IL-1β, CXCL1, CXCL2, and VCAM-1 in sepsis group were increased. Compared with sepsis group, the above-mentioned molecular levels of pae group were significantly decreased [TNFα: (63.39±9.55)pg/ml vs. (126.54±19.17)pg/ml ;IL-6: (64.03±8.82)pg/ml vs. (85.60±9.52)pg/ml;IL-1β: (69.52±9.23)pg/ml vs. (130.45±15.10)pg/ml;CXCL1: (2 600.19±379.54)pg/ml vs. (4 903.89±533.42)pg/ml;CXCL2: (93.71±10.83)pg/ml vs. (127.24±13.92)pg/ml;VCAM-1: (112.22±13.49)pg/ml vs. (149.32±15.65)pg/ml, both P<0.05]. RT-qPCR results showed that the mRNA expressions of TNFα, IL-6, IL-1β, CXCL1, CXCL2 and VCAM-1 in the sepsis group were increased compared with the control group; Compared with sepsis group, the IL-6 mRNA (1.271±0.139 vs. 1.920±0.191, P<0.05), IL-1βmRNA (1.180±0.130 vs. 1.817±0.191, P<0.05), VCAM-1 mRNA (1.088±0.144 vs. 1.460±0.166, P<0.05) expression decreased significantly in the pae group. Compared with control group, the levels of P-p38MAPK and P-Src in sepsis group increased, and the level of VE-cadherin decreased. Compared with sepsis group, the levels of p38MAPK and P-p38MAPK in pae group were significantly decreased, and the level of VE-cadherin was increased (p38MAPK/β-actin: 1.125±0.078 vs. 1.520±0.164; P-p38MAPK protein: 1.639±0.133 vs. 2.112±0.222; both P<0.05). Conclusion:Paeoniflorin could improve the permeability of cardiac microvascular endothelium in sepsis rats and inhibit the secretion and expression of inflammation-related proteins and genes, which might be related to the inhibition of Src/VE-cadherin pathway by paeoniflorin.
