Objective To investigate the association between the three single nucleotide polymorphisms (SNP) in angiotensin Ⅱ type one receptor (AT1R) gene with coronary artery disease (CAD) in Chinese Han nationality.Methods Extracted DNA and RNA samples of peripheral blood white cells from 192 CAD patients and 189 healthy individuals in Jan 2011 to Oct 2013 from the general hospital of the PLA Rocket Force.Designed primes and the three SNPs as rs6801836,rs2675511 and rs5182 of AT1R gene were analyzed with allele-specific fluorogenic oligonucleotide probes in an assay combining extension and hybridization.Results The genotype and allele frequencies of the three SNPs were not significantly different between the control group and CAD group (x2 =0.047～2.226,all P＞0.05).The major haplotype constructed with linkaged rs6801836 and rs5182 was TT.The frequency of every haplotypes showed no significantly difference between the two groups (x2 =0.025～1.020,all P＞0.05).Conclusion The three polymorphisms of AT1R gene studied in this work showed no association with CAD susceptibility.

Moxibustion,which is simple for manipulation and effective,has always been a very important way for external treatment.Acupuncture and moxibustion were complementary to each other sincc ancient times.but modem people usually only pay attention to acupuncture and neglect the usage of moxibustion.In this paper the importance of moxibustion is expounded briefly.

Purpose To investigate the value of real-time three-dimensional contrast-enhanced ultrasound (RT3D-CEUS) for the evaluation of blunt renal trauma hemorrhage. Materials and Methods Nine healthy New Zealand white rabbits were randomly divided into three groups, and after heparinization, the models of ongoing hemorrhage of blunt renal trauma were developed by self-made minitype striker in the three groups with different force levels:77.2 N (group A), 106.2 N (group B), 135.1 N (group C). All rabbits were performed ultrasonography (US), color Doppler flow imaging (CDFI) and RT3D-CEUS before and after strike (within 20 minutes). The results achieved by US, CDFI, 2D-CEUS (A-plane results in RT3D-CEUS) and RT3D-CEUS were compared with each other, and further compared with the pathological results of the executed animals after blood pressure decreased lower than 40 mmHg. Results All rabbits showed traumatic renal lesions and it proved that the bigger the force the heavier the injury (group A: 1 case of levelⅠ, 2 cases of levelⅡ;group B:3 cases of levelⅢ;group C:1 case of levelⅢ, 2 cases of level Ⅳ ). After strike, US identified the presence of increasing hematoma under the capsule but could not detect active bleeding. In CDFI, only 1 case was detected ongoing hemorrhage. 2D-CEUS clearly presented the bleeding in all cases. RT3D-CEUS presented a vivid real-time and stereoscopical image of active hemorrhage in all cases and also showed that the wider the bleeding area was shorter than the shock duration time. Conclusion RT3D-CEUS can present a real-time dynamic bleeding and locate headstream of blood in renal trauma vividly and stereoscopically, and can be used to preliminarily evaluate the degree of ongoing hemorrhage in traumatic kidney.

Abstract:Photodynamic therapy(PDT)is a minimal invasive therapy that have been clinically approved for the cancer treatment with selective cell toxicity. When activated by appropriate wavelength of light, photosensitizers transfer the absorbed photon energy to the surrounding molecular oxygen to generate reactive oxygen species, which result in cell death, vessel damage and immune activation of tumor site. This paper summarize the main challenges and recent solutions for PDT application, such as the low tissue penetration of light, toxicity induced by nonspecific accumulation of skin and poor PDT effect of hypoxia tumor.

In this study, 1 065 infants and young children aged 24 months below in ethnic minorities gathering in poor rural areas in poor rural areas of Liangshan Yi Autonomous Prefecture of Sichuan Province and Gannan Tibetan Autonomous Prefecture of Gansu Province were investigated for their anemia status from October to November 2014, and the association between anemia and the utilization of maternal and child health services was analyzed. The prevalence of anemia in this area was 52.68%(561/1 065). After the adjustment of socio-demographic characteristics of mothers and infants, compared with infants aged 2-5 months, Han ethnic group, and infants whose mother was not anemic, the OR(95%CI) values of infant anemia for infants aged 6-12 months, 13-8 months, 19-24 months, ethnic minorities group, and infants whose mother was anemic were 11.65 (7.09-19.14), 9.91 (5.99-16.38), 5.87 (3.39-10.16), 1.55 (1.10-2.18) and 1.52 (1.14-2.04), respectively; Compared with infants whose child examination times not up to standard, and who were not only non-hospital delivered but also received inadequate number of inoculation, the OR (95%CI) values of infant anemia for infants whose child examination times up to standard, and who were not only hospital delivered but also received adequate number of inoculation were 0.60 (0.38-0.94) and 0.71 (0.52-0.98), respectively. The infants anemia is associated with the utilization of maternal and child health services.

Objective:To investigate the protective function and mechanism of β-hydroxybutyrate (β-HOB) on cisplatin (CP)-induced nephrotoxicity.Methods:C57BL/6 male mice aged 10 weeks were randomly divided into the following three groups: control group (no special treatment), β- HOB+CP group (mice received intraperitoneal injection of 20 mmol/kg β-HOB for 10 days), CP group (received intraperitoneal injection of normal saline for 10 days). CP group and β-HOB+CP group were given once cisplatin (20 mg/kg) intraperitoneal injection on the 8th day in the experiment. On the 10th day, all the mice were sacrificed. Renal pathology was evaluated by HE staining; blood samples were collected for blood urea nitrogen (BUN) and serum creatinine (Scr) measurement; immunohistochemistry staining was performed to detect the protein level of Caspase3, Cleaved-caspase3, mitogen-activated protein kinase (MAPK) and nuclear factor-κB (NF-κB) in renal tissues; Western blotting was used to detect the relative expression levels of p-MAPK/MAPK and p-NF-κB/NF-κB. In vitro experiment, HK-2 cells were set into three groups: control group, CP group, β-HOB+CP group, and β-HOB+CP+Sappanone A (Sap, MAPK-p38 activator) group. The expression levels of p-MAPK, p-NF-κB, Caspase3 and Cleaved-caspase3 were tested by cell immunofluorescence. The cell apoptosis and mitochondrial membrane potential (MMP) were examined by flow cytometry. DNA damage was detected by TUNEL staining. Results:In vivo experiments, the renal pathological injury score, BUN and Scr in CP group were significantly higher than those in control group (all P<0.05), while renal pathological injury score, BUN and Scr in β-HOB+CP group were lower than those in CP group (all P<0.05). The protein expression levels of p-MAPK, p-NF-κB, Caspase3 and Cleaved-caspase3 in CP group were higher than those in control group, while these indexes in β-HOB+CP group were lower than those in CP group (all P<0.05). In vitro experiments, compared with CP group, the MMP was higher in β-HOB+CP group; the ratio of cell apoptosis, the expression of Caspase3, Cleaved-caspase3, p-MAPK and p-NF-κB, and the number of TUNEL staining positive cells were significantly lower (all P<0.05). Compared with β-HOB+CP group, the MMP in β-HOB+CP+Sap group was lower; the ratio of cell apoptosis, the expression of Caspase3 and Cleaved-caspase3, and the number of TUNEL staining positive cells were significantly higher (all P<0.05). Conclusions:β-HOB can alleviate the acute renal injury induced by cisplatin, which may be related to the reduction of apoptosis and inhibition of MAPK/NF-κB pathway.

Objective To provide a scientific basis for the formulation of effective incentive measures for rural health workers,by analyzing the factors influencing their work enthusiasm and constructing an incentive mechanism framework.Methods A field questionnaire survey and personal in-depth interview were conducted on 803 health technicians from 45 township health centers in Shandong,Anhui and Shanxi provinces.The study covered economic,management,education and career supports aspects,and the data were analyzed in descriptive,multi-level model and correlation analyses.Results The work enthusiasm scoring of rural health workers was 89.83 + 9.54.Workload,doctor-patient relationship,work competence and income index were the four influencing factors,with the differences showing statistical significance(P ＜0.05).The income index (income expectancy/real income affects work) influences the enthusiasm negatively,while the rest of the factors were positive.Work enthusiasm was positively correlated with three dimensions of job performance.The satisfaction of interpersonal relationship,workload and competence were positively correlated with work enthusiasm.The correlation indexes are respectively 0.35,0.33 and 0.21 (P ＜ 0.01).Conclusions To motivate primary health institutions and their health workers,the authorities should focus on the economic factors,and take into account non-economic ones,while improving the performance-based wage system and creating a fair workplace culture.

Objective:To explore the risk factors for early mortality in heart transplant(HT)recipients and construct a nomogram prediction model.Methods:From 2018 to 2022, preoperative clinical data were retrospectively reviewed for 163 consecutive HT recipients.Risk factor variables were shortlisted by univariate correlation analysis based upon early(90-day)postoperative patient survival.Lasso regression was then employed for screening all variables and common variables were combined.A nomogram was constructed for predicting the probability of early mortality after considering actual circumstance.Receiver operating characteristic(ROC)curve, area under the ROC curve(AUC), Harrell's C-index and calibration curves were employed for evaluating and internally validate the performance of the model.Decision curve analysis was performed for assessing clinical utility of the model.Results:In survival and mortality groups, mechanical ventilation, nervous system lesions, use of extracorporeal membrane oxygenation, red blood cell count ≤3.52×10 12/L, mean pulmonary arterial pressure>27 mmHg, pulmonary vascular resistance>4.01 Wood Unit, albumin≤33 g/L, aspartate aminotransferase >50 U/L, hemoglobin ≤108 g/L, platelet count ≤109×10 9/L and total bilirubin>57 μmol/L demonstrated statistically significant differences( P<0.05). At the same time, according to actual situations and different variables, hemoglobin ≤108 g/L, albumin ≤33 g/L, platelet count ≤109×10 9/L, total bilirubin>57μmol/L, aspartate aminotransferase>50 U/L, nervous system lesions and average pulmonary arterial pressure >27 mmHg were seven variables.And a nomogram with relatively high reliability was constructed for predicting the probability of early mortality post-HT(nomogram model evaluation, AUC 0.917, C index 0.910 and good calibration curve). Decision curve analysis indicated that the nomogram could benefit HT recipients. Conclusions:Risk factors have been identified for early mortality in HT recipients.And the nomogram prediction model offers a simple and reliable tool for predicting early mortality post-HT.It has important implications for individualized treatment of HT candidates.

Objective:To analyze the effects of β-receptor blockers on all-cause mortality in elderly patients with mild-moderate chronic heart failure(CHF)and chronic obstructive pulmonary disease(COPD), and to analyze risk factors relevant to death.Methods:This was a multicenter retrospective cohort study from January 2013 to December 2017.The 400 elderly patients with CHF and COPD treated in Rizhao People's Hospital(187 cases), Shandong Provincial Hospital(122 cases)and Beijing Anzhen Hospital(91 cases)were enrolled.The patients receiving β-receptor blockers were included as β-receptor blockers group(n=200), and the patients matching for similar age and cardio-pulmonary function, not receiving β-receptor blockers were selected as the control group(n=200). All patients were followed up until December 31, 2019.The primary endpoints were all-cause mortality.The risk factors for all-cause death were compared and analyzed.Results:Among 400 patients, the average age was(72.2±11.7)years with 226 males(56.5%). There was no significant difference in baseline data such as age, gender ratio, body mass index, heart function, lung function, and treatment regimen after matching between the two groups(all P>0.05). At end of 3-years follow-up, risks of all-cause mortality( χ2=7.284, P<0.01), and re-hospitalization risk due to worsening heart failure( χ2=6.782, P<0.01), acute exacerbation of COPD( χ2=6.921, P<0.01)were significantly reduced in β-receptor blockers group versus control group.Multivariate Cox regression analysis showed that age ≥75 years( HR=2.142), diabetes( HR=1.929), ratio of baseline forced expiratory volume in the first second / forced vital capacity <66.8%( HR=1.114), baseline glomerular filtration rate <72.0 ml/min( HR=3.572)and left ventricular ejection fraction <46.4%( HR=2.294)at end of 3-year follow-up were risk factors for mortality, whileβ-receptor blockers( HR=0.745)was a protective factor(all P<0.05). Conclusions:β-receptor blockers can significantly reduce the mortality and re-hospitalization rate in elderly patients with CHF and COPD.

Objective:To determine the application effect of the "full chain" information-based health management model in the home care of children with bronchial asthma.Methods:Sixty children with bronchial asthma who were hospitalized in the Respiratory Department of Xuzhou Children's Hospital from January to June 2020 were selected and divided into a control group and an observation group according to a random number table with 30 cases in each group. The control group received routine nursing care, and the observation group implemented a "full-chain" informatized health management on the basis of the control group.The intervention time was 6 months. The condition control, medication compliance, self-management and airway function were observed and compared between the two groups.Results:After 6 months of intervention, the frequency of attacks, emergency cases, the medication compliance, the maximum expiratory flow rate, symptom days and peak expiratory flow days were 6.67%(2/30), 3.33%(1/30), 93.33%(28/30), (1.83±0.23) L, (163.00±6.74) d, (168.00±3.78) d in the observation group, and 26.67%(8/30), 20.00%(6/30), 66.67%(20/30), (1.67±0.24) L, (144.00±5.88) d, (157.00±4.08) d in the control group. The differences were statistically significant (χ 2 values were 4.320, 4.043, 6.667, t values were 2.636, 11.635, 10.833, P<0.05). There was no significant difference in the ratio of forced expiratory volume and forced expiratory volume in forced vital capacity in the first second after 6 months of intervention between the two groups ( P>0.05). Conclusions:"Full chain" information health management can reduce the number of attacks and emergency visits of children with asthma, effectively improve medication compliance, thus improving airway function and improving the quality of life of children.
