Objectives To explore the correlation between the heteroplasmy level of mt5178C>A mutation in ND2 gene of mitochondria DNA and essential hypertension(EH)in middle-aged and elderly adults.Methods EH patients and normotensive controls were recruited consecutively from 2014-2015 from general population.Demographics,clinical characteristics and blood leukocytes were collected.The mt5178C>A mutation heteroplasmy level was quantified by the rapid and sensitive realtime polymerase chain reaction(PCR) method for each participant.Results A total of 108 EH patients and 109 controls were recruited.The mt5178C>A mutation heteroplasmy level was(42 ± 11%)in EH patients and (54± 13)% in control subjects,with statistically significant difference between the two groups(P<0.01).Using a two-step cluster analysis,the mt5178C>A heteroplasmy level exceeding 44% was associated with a decreased risk of EH(OR=0.18,95%,CI:0.10-0.31,P<0.01).Correlation analysis showed mt5178C> A heteroplasmy level was significantly negatively correlated with both systolic blood pressure (r =-0.38,P< 0.001) and diastolic blood pressure (r =-0.49,P< 0.01)in 109 controls.Logistic regression analysis demonstrated that in single-factor analysis,mt5178C > A heteroplasmy level (OR =0.82,95 % CI:0.77 0.87,P < 0.01) was protective factor for EH,however,BMI(OR=1.30,95%CI:1.12-1.45,P<0.01),total cholesterol(OR=2.13,95%CI:1.39-3.28,P=0.00),triglyceride(OR=7.62,95%CI:3.45-16.84,P<0.01)and blood urea nitrogen(OR =1.35,95 % CI,P =0.03) were risk factors for EH.And a multiple logistic regression analysis showed that mt5178C> A heteroplasmy level (OR =0.83,95 % CI:0.78-0.89,P< 0.01) was independent protective factor for E H,however,only total cholesterol (OR =2.17,95 % CI:1.58-2.98,P =0.02) and low density lipoprotein cholesterol (OR =0.06,95% CI:0.01-0.83,P =0.04) were independent risk factors for EH,and the P at critical 0.05 value.Conclusions Mitochondrial ND2 gene 5178C> A mutation heteroplasmy level exerts protective role against EH in middle-aged and elderly adults in Chinese population.

Objective:To explore the influencing and prognosis factors of emphysematous urinary tract infection (EUTI).Methods:The baseline clinical data of the patients admitted to Shandong University Qilu Hospital (Qingdao) from December 2013 to June 2020 and diagnosed with EUTI were analyzed retrospectively. The patients with non-EUTI (NEUTI) during the same period were selected as the control group. The baseline characteristics between the two groups were compared. Logistic regression analysis method was used to analyze the influencing factors of EUTI.Results:(1) 24 EUTI patients and 53 NEUTI patients were included in the present study. Compared with the NEUTI group, the hemoglobin level was lower ( t=-5.245, P<0.001) and the levels of blood urine nitrogen ( Z=-4.361, P<0.001), serum creatinine (Scr, Z=-4.543, P<0.001), blood glucose ( Z=-2.608, P=0.009), and triacylglycerol ( Z=-2.408, P=0.016) were higher in the EUTI group. The proportions of diabetes mellitus ( χ2=13.453, P<0.001) and chronic kidney disease ( χ2=17.936, P<0.001) in the EUTI group were higher than those in the NEUTI group. Increasing Scr was the risk factor of EUTI in patients with urinary tract infection ( OR=1.011, 95% CI 1.001-1.020, P=0.025). (2) Escherichia coli ( E.coli, 14 cases, 58.3%) was the most common causative organism. The other causative organisms included Klebsiella pneumoniae (2 cases, 8.3%), Enterococcus faecium (1 case, 4.2%), Pantoea (1 case, 4.2%), and mixed bacteria of E.coli and Enterococcus faecium (1 case, 4.2%). Ten cases of E.coli were extended-spectrum β-lactamases (ESBL)-positive. (3) Of the 24 patients with EUTI, 4 patients had adverse outcomes. The length of stay ( Z=-2.457, P=0.014), blood urea nitrogen ( t=2.432, P=0.024), shock ( P=0.002), autoimmune disease ( P=0.022), and white blood cell count ( Z=-2.091, P=0.036) were statistically different between good prognosis group ( n=20) and poor prognosis group ( n=4). However, logistic regression analysis results showed that neither was the influencing factor of poor prognosis of EUTI. Conclusions:The elevated Scr level is the independent influencing factor of EUTI among urinary infection patients. E.coli is the most common pathogenic bacteria, and ESBL-positive bacteria are common.

Objective To compare the efficacy of different rehabilitation models on acalculia after acquired brain injury. Methods 113 cases were randomly assigned to 3 groups: control group(n=37), computer-assisted training group(n=38) and face-to-face training group(n=38). The control group just received cognitive dysfunction evaluation. The training groups received cognitive rehabilitation training 5 days a week and 30 minutes a day which sustained for 6 weeks. And 33 patients were selected to prolong for 12 weeks. They were evaluated with Revised EC301Calculation and Number Processing Battery in Chinese version (EC301-CR) at the beginning, the 6th week point and the 12th week point respectively. Results 6-week after treatment, The performance of both the computer-assisted training group and face-to-face training group significantly improved(P<0.001); It showed that computer-assisted group>face-to-face group>control group(P<0.001) both 6 weeks and 12 weeks latter. Significant negative correlation was found between age and performance of EC301-CR(P<0.05).Conclusion The effect of computer-assisted training on acalculia is superior to face-to-face training; The first 6 weeks of training is the best period for rehabilitation; The younger the patient is, the better results are.
