Objective To analyze the characteristics of pulse pressure index(PPI) and its value in predicting the risk for cerebral and cardiac vascular events in old males with hypertension. Meth-ods The 24-hours ambulatory blood pressure monitoring was performed in a total of 265 elderly men with essential hypertension(EH). The patients were classified into 3 groups based on the lev-el of PPI.PPI≤0.400(103) ,0. 401-0. 500(124) ,and≥0.501(38). Results There was significant difference in PP between day-time and night-time in hypertensive patients. The change of PPI was less than that of PP. With the increase in PPI, SBP(24 h, day-time, night-time), PP(24 h, day-time, night-time), the load of SBP(night-time), systolic blood pressure variation(BPV, 24 h, day-time) were raised significantly (P<0.01); while DBP(24 h, day-time, night-time), nocturnal de-cline in BP and the load of DBP(day-time) declined with the decrease in PPI (P<0.01). High PPI would increase the incidence of cardiac-cerebral vascular events (P < 0.01). Conclusion PPI is a useful parameter in clinical evaluation of arteriosclerosis. It may also have prognostic value for cardiac-cerebral vascular events in elderly men with EH.

Clinical competence was estimated for grades 2011-2013 general practitioners (GPs)trained by the DxR Clinician software.Clinical cases were solved on computer.And the abilities of diagnosis,thinking and handling were assessed.The average score of all GPs was 61.68 ± 10.69.The average score of diagnostic ability was the highest at 71.82 ± 15.47 (weighted score of 25.1).The average score of thinking ability was 62.36 ± 10.40 (weighted score of 28.1).And the average score of handling ability was the least at 42.27 ± 18.22 (weighted score of 8.5).Significant differences in average scores existed between grades 2011 and 2013 (P ＜ 0.05).Significant differences in score of clinical thinking ability existed between grades 2011,2012 and 2013 (P ＜ 0.01) respectively.None of them passed the part of handling.The longer period of training,the higher scores the residents obtained.Since the ability of clinical handling fared the worst,targeted training should be strengthened.

Objective To understand the drug resistance and changes of Pseudomonas aeruginosa in Tianjin Medical University Eye Hospita and to explore the relationship between the drug resistance and the dosage of antimicrobial agents, so as to provide the basis for clinical rational drug use.MethodsUsage of antibiotics in our hospital during 2012 to 2016 were analyzed retrospectively, and the drug resistance of pseudomonas aeruginosa were calculated respectively.SPSS 22.0 software was used to analyze the drug resistance and the frequency of use of antimicrobial agents (DDDs).ResultsResistance rate of pseudomonas aeruginosa to aztreonam, ceftazidime and meropenem were decreased gradually.Resistance rate of pseudomonas aeruginosa to gentamicin increased gradually.The resistance of pseudomonas aeruginosa to piperacillin, imipenem, cefepime, evil ciprofloxacin, piperacillin/tazobactam tazobactam and cefempidone/sulbactam is in a state of fluctuation.Piperacillin DDDs were significantly negatively correlated with gentamicin resistance.There was a significant positive correlation between imipenem DDDs and gentamicin resistance and there was a significant negative correlation between imipenem DDDs and drug resistance rates of piperacillin, imipenem, ceftazidime, meropenem, levofloxacin and cefoperazone/sulbactam.There was a significant positive correlation between aztreonam DDDs and ceftazidime, meropenem, ciprofloxacin and cefoperazone/sulbactam, There was a significant negative correlation between cephalosporin DDDs and gentamicin resistance rates.There was a significant positive correlation between the DDDs of piperacillin/tazobactam and the resistance rate of piperacillin/tazobactam;the resistance rates of cefoperazone/sulbactam DDDs to aztreonam and meropenem were Significant negative correlation.ConclusionDrug resistance of pseudomonas aeruginosa and the dosage of clinical antibacterial drug is closely related, suggesting that clinicians should use antibiotics for clinical rationally, in order to reduce the number of drug resistance of pseudomonas aeruginosa.

Objective To investigate the effects of collateral pathways on prognosis of cerebral infarct patients with prior transient ischemic attack (TIA) and its role in neuroprotective mechanism of TIA. Methods A total of 164 cases of the first ever cerebral infarct patients were consecutively allocated into three groups: A , B and C group according to their age.Three groups were divided into two subgroups respectively based on the absence or presence of prior ipsilateral TIA: A1, A2, B1, B2, C1, C2 group. Neurological dysfunctional scores at admission and 1 month after treatment, barthel index, collateral pathways status, and cerebral infarction volume were evaluated respectively. The relationship between development of collateral pathways and prognosis was assessed at the same time. Results The neurological dysfunctional scores and cerebral infarction volume of patients in A1 group and B1 group were significantly lower than those of A2 group and B2 group (P

Objective To explore the most suitable equation in accessing renal function for the elderly type 2 diabetic patients, and its clinical utility in combination with hypersensitive C-reactive protein (hsCRP). Methods The new Cystatin C-based equations for estimated glomerular filtration rate (Cys-eGFR) and conventional predictive equations were compared with isotopic GFR (iGFR) by linear regression analysis, paired t-test, Bland and Altman procedures and non-parametric receiver operating characteristic (ROC) curves. The new Cys-eGFR equation and hsCRP were also incorporated for detecting renal disease in this population. Results The new Cys-eGFR equation had a better relativity with iGFR (r= 0.767, P＜0.001), a less bias (bias: 0.0007, P＞0.05), a higher conformance (2SD: 21.56), higher sensitivity (90.7%) and specificity (88.6%) for diagnosing moderate decrease in renal function. There was a negative relationship between the new Cys-eGFR and hsCRP (r=-0.655, P＜0.01). When the new Cys-eGFR was 67.06 ml· min-1 ·1.73 m-2 and hsCRP was 5.65 mg/L, the combination of Cys-eGFR and hsCRP was better than the combination of serum creatinine and urine albumin/creatinine ratio in screening stage 3 chronic kidney disease (95%vs.46%). Conclusions The combination of new Cys-eGFR equation and hsCRP may screen an early decrease of moderate GFR.

Objective To investigate the influence of stigma on QOL of patients with mental disorders.Methods By using Link stigma series scale and schizophrenic quality of life scale,we assessed and analyzed 406 psychiatric patients′stigma and QOL, as well as the correlation and influence between them.Results The score of perceived devaluation-discrimination dimension of the stigma scale had positive correlation with total score of QOL,score of psycho-social dimension and score of motivation and energy dimension (P <0.05).The scores of challenge dimension and separation dimension in the stigma scale had positive correlation with motivation and energy dimension of the QOL scale (P <0.05).Regression analysis showed that stigma did not have influence on QOL of patients with mental disorders.Conclusion Stigma in psychiatric patients has no significant influence on QOL,but correla-tion relationship exists between them.The higher score of perceived devaluation-discrimination dimension,challenge dimension and separation dimension of stigma scale,the poor QOL the patient would have.

Objective To investigate the effects of blocking gastrin receptor on the proliferation,apoptosis and expression of key proteins in the related pathway in gastric cancer cell lines.Methods In the experimental group,the gastric cancer cell lines SGC-7901 and AGS cells were treated with 5 mmol/L proglumide,a kind of a gastrin receptor antagonist.And the normal cultured gastric cancer cells SGC-7901 and AGS were used in control group.The growth of each group was detected by MTT assay;the cell growth curve was drawn by flow cytometry;the cell cycle of each group was detected by flow cytometry.Annexin V-FITC/PI double staining was used to detect the cell growth of apoptosis.The relative mRNA expression of β-catenin,nuclear factor-P65,mammalian target of rapamycin and glycogen synthase kinase 3 beta in Wnt,NF-κB and PI3K-AKT-MTOR pathways were detected by RT-qPCR.The expression of β-catenin protein was detected by Western blotting.Results After treatment with proglumide,the growth of the cells in the experimental group was lower than that in the control group;and the proportion of S phase cells in the cell cycle was also lower than that in the control group,but the proportion of cells in G0/G1 phase was higher than that in the control group(P<0.05).The percentage of apoptotic cells was also increased after treatment with proglumide(P<0.05).Furthermore,proglumide treatment significantly reduced the expression of β-catenin at both mRNA and protein levels(P<0.05).Conclusion Blocking gastrin receptor can down-regulate the expression of β-catenin,inhibit the cell proliferation and promote the cell apoptosis in gastric cancer cells.

OBJECTIVETo explore the effects of early intervention of acupuncture on urinary function reconstruction of neurogenic bladder after spinal cord injury, so as to find the optimal treatment timing of acupuncture.

METHODSFifty-three patients of neurogenic bladder after spinal cord injury were randomly divided into a prior-to-catheter group (25 cases) and a posterior-to-catheter group (28 cases). For the prior-to-catheter group, one week before the removal of catheter, acupoints on the abdomen and back such as Guanyuan (CV 4), Zhongji (CV 3), Baliao (Shangliao (BL 31), Ciliao (BL 32), Zhongliao (BL 33), Xialiao (BL 34), Jiaji (EX-B 2) and acupoints at distal end such as Zusanli (ST 36) and Sanyinjiao (SP 6) were selected; after the catheter removal, simple method. of water column was used to measure bladder capacity pressure to classify the type of bladder, and then different acupuncture manipulations were given; intermittent catheterization was performed if condition was allowed. The posterior-to-catheter group applied identical treatment after removal of catheter as the prior-to-catheter group. The treatment was given 5 times per week; after one-month treatment, five aspects including the time of first effective urination, time of establishing reflex urination, average residual volume of urine, time of residual urine less than 100 mL and quality of life (QOL) were evaluated.

RESULTSAfter treatment, the time of first effective urination, time of establishing reflex urination, average residual volume of urine and time of residual urineless than 100 mL in the prior-to-catheter group were all superior to those in the posterior-to-catheter group (all P<0. 05) ; the score of QOL was improved in two groups after treatment (both P<0. 01), but the difference between two groups was not statistically significant (P>0. 05); each index of urination function was not significant among patients with different injured segments of spinal cord (all P>0. 05).

CONCLUSIONThe early intervention of acupuncture (prior to catheter) has obvious improving function on establishing balanced bladder in patients with neurogenic bladder after spinal cord injury, which is superior to acupuncture intervention after removal of catheter, however, the effects of different injured segments on establishing balanced bladder are not different.
