Objective To explore the effect of individualized nursing intervention on life quality and efficacy of senile patients undergoing percutaneous coronary intervention (PCI) during perioperative period. Methods 212 senile patients with PCI were divided randomly into the control group and the study group with 106 patients in each. The individualized nursing intervention and routine nursing were used in the study group, while only routine nursing was used in the control group. The patients in both groups were investigated in 3 days after PCI with questionnaire designed by the author to compare life quality and efficacy during perioperative period. Results The occurring rate of side-effect of the study group was lower than that of the control group, and the satisfaction degree, quality of life and efficacy were also higher than those of the control group. Conclusions Effective individualized nursing intervention can cor-rect the patients' pre-treatment behavior, provide more health information to the patients and give them the rules of self-nursing, so as to reduce the occurrence rate of complication, improve the patients quality of life and curative effect.

This paper aims to develop a method for the determination of aloe-emodin, rhein, chrysophanol and physcion and study the pharmacokinetic properties of four anthraquinones in rat plasma after oral administration of gardenia and rhubarb decoction. The plasma concentrations at different time points of four anthraquinones were determined by HPLC-FLD method. Plasma samples were extracted with liquid-liquid extraction procedure. Plasma samples were separated on a C18 column (4.6 mm x 150 mm, 5 μm), using 0.2% acetic acid and methanol as mobile phase at a flow rate of 1.0 mL min(-1) with gradient elution. The excitation and emission wavelengths were set at 430, 525 nm, respectively. DAS 2.0 software was applied to calculate the pharmacokinetic parameters. The results showed four anthraquinones can be absorbed. The main parameters of aloe-emodin, rhein, chrysophanol and physcion were as follows: C(max) for aloe-emodin was (0.085 ± 0.058), (3.772 ± 1.152), (0.464 ± 0.267), (0.028 ± 0.008) mg x L(-1) respectively; t(max) for rhein was (1.042 ± 0.510), (0.805 ± 0.307), (1.167 ± 0.283), (0.616 ± 0.162) h respectively; t½ for chrysophanol was (3.557 ± 1.250), (6.879 ± 1.126), (5.196 ± 2.032), (4.337 ± 1.816) h; AUC(0-t) for physcion was (0.504 ± 0.130), (9.558 ± 1.106), (2.545 ± 1.554), (0.052 ± 0.018) mg x h x L(-1). This paper developed a selective, accurate and sensitive HPLC-FLD method for the simultaneous determination of four anthraquiones in rat plasma.

This study is to investigate the protection effect of schisandrin B (Sch B) against oxidation stress of HK-2 cells induced by cisplatin and the mechanisms involved. HK-2 cells were cultured and divided into different groups: solvent control group, cisplatin exposure group, positive group, Sch B treatment group. Cell viability and toxicity were evaluated by MTT and LDH assay. GSH level and SOD enzymes activities were also measured. DCFH-DA as fluorescence probe was used to detect ROS level by fluorescence microplate reader. Nrf2 translocation was detected by Western blotting. Real time Q-PCR was used to detect expressions of NQO1, HO-1 and GCLC mRNA level. The results showed that Sch B could significantly inhibit the decline of cell viability induced by cisplatin treatment (P < 0.05) and the protective effect was in a dose dependent manner. Furthermore, Sch B treatment significantly inhibited the increase of ROS level induced by cisplatin and reversed the decrease of GSH level (P < 0.05). When Sch B concentration was up to 5 micromol x L(-1), SOD enzyme activities were also enhanced significantly compared with that of the cisplatin group (P < 0.05). It was shown that Sch B could cause nuclear accumulation of Nrf2 in association with downstream activation of Nrf2 mediated oxidative response genes such as GCLC, NQO1 and HO-1. These results suggested Sch B could protect against the oxidative damage of HK-2 cells induced by cisplatin via the activation of Nrf2/ARE signal pathway.

Objective:Immune cells and inflammatory mediators play important roles in the development of atherosclerotic vascular inflammation.This study focuses on the direct effect ofIL-27 on human coronary artery endothelial cells.Methods:In this study,the effects of IL-27 and TNF-α on inflammatory cytokines and chemokines were investigated.Results:IL-27 could significantly enhance the TNF-α-mediated upregulation of inflammatory cytokine IL-6 and chemokines CCL5 from human coronary artery endothelial cells.The release of IL-6 and CCL5 was significantly suppressed by specific signaling molecule inhibitors.Conclusion:The induction of these mediators from the human coronary artery endothelial cells could be differentially regulated by the c-Jun N-terminal kinase,p38 mitogen-activated protein kinase,and nuclear factor-κB pathways.These results provided new insights into the effect of IL-27 on the TNF-α mediated activation of human coronary artery endothelial cells in atherosclerotic vascular inflammation.

Objective To compare the traditional electrophysiological testing with modified methods for differential diagnosis of Radial Tunnel Syndrome (RTS).Methods A total of 87 selected patients were initially diagnosed as Lateral Epicondylitis (LE) or Tennis Elbow (TE) by doctors from the Outpatient Department of Orthopedics and Rehabilitation.Medical history was asked.Patients received physical examination and examinations for the sensory nerve action potential (SNAP) of superficial radial nerve,the compound muscle action potential (CMAP) of radial nerve and needle electromyography (EMG) to record the muscle Motor Unit Action Potentials (MUAPs).Then,the modified methods for CMAP of radial nerve were conducted on the forearm in the neutral,pronation and supination positions.Three values of CMAP latency were compared.RTS was diagnosed when the difference value ≥0.3 ms.The x 2 test was used to compare the positive detectable rates of the two methods for the RTS diagnosis.Results Thirteen out of 87 patients were diagnosed as RTS,among which three had interosseous nerve lesion and one had superficial radial nerve lesion.The traditional EMG failed to diagnose the remaining 9 RTS cases.These patients were finally diagnosed due to their latency difference of radial nerve CMAP ≥0.3ms when their forearms were examined in three positions.Conclusion The modified electrophysiology method shows a higher positive rate for the diagnosis of RTS.(P＜0.05).

Objective To discuss the clinical management and significance of the prenatal diagnosis of Fetal Choroid Plexus Cysts(CPC).Methods From May 2004 to March 2007,55 cases of fetal CPC diagnosed by B-ultrasound during second trimester were prospectively studied.Each case was studied regarding fetal chromosome karyotype,disappearance weeks of the cyst,the clinical outcome and follow-up results respectively.Result The cases were diagnosed during 16-25 gestational weeks.The diameters of the cysts varied from 0.2 cm to 2.4 cm.There were 25 cases of bilateral cysts and 30 cases of unilateral or 50 cases of isolated CPC and 5 cases of complicated CPC.The cysts of all cases who continued pregnancy disappeared before 28 weeks.Fetal chromosome karyotypes were obtained in 50 cases.Among them,two cases were 18-trisomy,and one case was 21-trisomy.Five cases were terminated pregnancy because of abnormal chromosome karyotype or malformation during second trimester.One neonate was diagnosed as ventricular septal defect among 50 cases of follow up.Among these six cases,three were from advanced-age pregnant women,five cases were with abnormal fetal structure and five cases were with the diameter of bilateral or unilateral cysts more than 1.0 cm.Conclusion(1)Fetal CPC can be diagnosed during second trimester,and the majority disappear before 28 gestational weeks.(2)High risk factors for fetal abnormal chromosome karyotype may be:advanced-age pregnant women,abnormal structure of fetus,and the diameter of bilateral or unilateral cyst more than 1.0 cm.It is suggested that fetal CPC with the high risks should receive fetal chromosome karyotype test during pregnancy.

Abstract: Objective　To analyze the epidemic characteristics of hand, foot and mouth disease (HFMD) in Nanping City, Fujian province and to provide the basis for formulating effective prevention and control measures as well as evaluating the efficacy of prevention and treatment. Methods　Descriptive epidemiological method was used to analyze the incidence data of HFMD in Nanping City from 2012 to 2021. Results　A total of 49 231 cases of HFMD were reported in Nanping City from 2012 to 2021. The incidence fluctuated greatly over the 10-year period, ranging from 76.10/100 000 to 308.93/100 000, with an average incidence of 184.99/100 000 per year. The overall incidence and the number of cases showed a fluctuating downward trend over time, but the incidence was high in the next year, and there were statistically significant differences in the incidence rates between different years(χ2=8 169.176, P<0.001). There were significant regional differences in the incidence, the top three average annual incidence rates were: Guanze County (370.76/100 000), Zhenghe County (295.31/100 000) and Wuyishan City (250.31/100 000). There were two peaks of HFMD incidence each year, with the first occurring in May and June and the second occurring in September and October. The incidence rate was higher among males (215.86/100 000) than females (152.93/100 000), and males were more susceptible than females (RR=1.412, 95%CI=1.387-1.438). The cases were mainly aged 0-4 years, accounting for 86.25% (42 461/49 231) of all cases, and the incidence rate gradually decreased with increasing age (χ2trend=570,105.801, P<0.001). The majority of cases (85.22%, 41 953/49 231) occurred in children living in scattered areas, followed by children in kindergartens (12.39%, 6 101/49 231). The etiological results showed a total of 3 476 laboratory-confirmed cases, and the proportion of three (classes) of enterovirus positivity varied each year, with different pathogen compositions showing statistical significance (χ2=584.613, P<0.001). In addition to the years 2015-2017, during which Cox A16 and EV71 were the dominant strains, other years were dominated by other enteroviruses, with EV71 being the main type in severe and fatal cases of HFMD in Nanping City. Conclusion　Nanping City should strengthen health education for children living in the diaspora and in day-care centers, enhance surveillance of epidemics and pathogenology, improve vaccination rates against EV71, focus on the detection and typing of other enteroviruses, and implement effective prevention and control measures for HFMD.
