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 compare the diagnostic value of dual-phase 99Tcm-MIBI scintigraphy and color Doppler ultrasonography for localizing ectopic parathyroid lesions in patients with HPT secondary to chronic renal failure (CRF-HPT).Methods Medical records of 368 CRF-HPT patients (204 males,164 females,age range:12-76 years) from January 2011 to April 2015 were retrospectively analyzed.Pathological results was used as the gold standard for the diagnosis of HPT.The sensitivity and specificity of dualphase 99Tcm-MIBI scintigraphy and color Doppler ultrasonography for the diagnosis and localization of ectopic parathyroid lesions were studied and compared by x2 test.Results A total of 1 398 positive lesions were found in 356 patients by dual-phase 99Tcm-MIBI scintigraphy,and 54 ectopic lesions occupying 3.9％(54/1 398) of positive lesions were detected by delayed planar imaging or SPECT/CT fusion imaging in 45 patients.Most of them (n =53) were confirmed by pathology.While only 966 positive lesions were found in 254 patients and no ectopic lesions were identified by color Doppler ultrasonography.The diagnostic sensitivity and specificity of dual-phase 99Tcm-MIBI scintigraphy for CRF-HPT lesions were 97.2％(1 375/1 415) and 53.1％(26/49),respectively.The corresponding parameters of color Doppler ultrasonography were 66.4％ (940/1 415) and 46.9％ (23/49),respectively.The specificity of ectopic lesion localization by radionuclide imaging was 98.1％ (53/54).The accuracy of dual-phase 99Tcm-MIBI scintigraphy was significantly higher than that of color Doppler ultrasound in lesion localization (x2 =20.8,P ＜ 0.05).Conclusion Compared to color Doppler ultrasonography,99Tcm-MIBI scintigraphy is more sensitive in identifying the positive lesions and more specific in localizing the ectopic parathyroid lesions in patients with CRF-HPT.

Employee motivation is to meet their needs and improve their productivity and work enthusiasm for the organization.Therefore,an accurate understanding of their needs is a prerequisite for the implementation of effective motivation.In view of this,we conducted a questionnaire survey of incentive factors for young medical staff at a public hospital.This study aimed at analyzing different incentive factors among medical staff with different seniority and job categories as well as their differences,in an effort to provide references for fine human resource management and motivation implementation at public hospitals.

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.

Objective To investigate the inflammation levels of 2-diabetes patients before and after 3 months of improving glycemic control.Methods A longitudinal study was performed in a subgroup of 48 subjects with T2D and poor glycemic control.Forty-four healthy individuals were taken as control group.The serum concentration of C-reactionprotein (CRP),interleukin-6 (IL-6),interleukin-6 (IL-8),transforming growth factor-β1 (TGF-β1) and transforming growth factor-β1 (MCP1) in all participants were measured simultaneously by multiplexed Luminex assay.Results The serum levels of CRP,MCP-1 of 2-diabetes patients were 3.96 (3.45,5.58) mg/L and (195.0± 129.8) ng/L,significant higher than those in control group (2.25 (1.24,3.22) mg/L,(148.5±85.7) ng/L),and the differences were significant(t=-2.580,P=0.010;t=-2.118,P =0.047).No significant difference was found in the serum levels of IL-6,IL-8,TGF-β lbetween the two groups (P＞0.05).TGF-β1 level in patients with good glycemic control decreased to 26.85 (23.17-31.12) ng/l,significant lower than that before glycemic control (43.5(26.5-62.25) g/L;Z=-2.191,P=0.028),and there were no significant differences among the other 4 kinds of inflammatory factors before and after blood glucose control(CRP:Z =-0.937P =0.372;IL-6:Z =-0.875,P =0.396;IL-8:Z =-1.215,P =0.286;MCP-1:t =-1.846,P=0.065).Conclusion Low grade systemic inflammation status in T2D patients.Improvement of glycemic control reduces TGF-β1 levels and plays a key role in delaying the development of diabetic nephropathy.

Objective To provide a comprehensive reference index for different mouse models of herpes simplex virus 1 (HSV-1) infection by investigating the related clinical manifestations, pathological features and characteristics of viral distribution in tissues and organs of BALB/c mice infected with different HSV-1 strains by using different strategies.Methods Acute infection models were established by challenging BALB/c mice at age three or six weeks with HSV-1 17+ and McKrae strains via intranasal and corneal administrations.Correspondingly, chronic infection models were established with BALB/c mice through subcutaneous and foot pad injections.Results Although all experimental mice showed trichiasis and roachback, there were differences in weight and fatality rate among different groups.Results of the quantitative PCR detection indicated that the proliferation of HSV-1 in the nervous tissues (brain, spinal cord, trigeminal ganglion) varied among different groups.The pathological examination indicated that in the acute infection groups, significant pathological changes only occurred in the brain tissues, while in the chronic infection groups, pathological injuries only occurred in the trigeminal ganglia.Although a key index latency-associated transcript (LAT) was not detected in the trigeminal nerve tissues of mice in the chronic infection groups, co-culturing the tissues with Vero cells resulted in infectious lesions in the cells.Conclusion This study indicates that there are significant differences in weight and fatality rate among different BALB/c mouse models of HSV-1 infection.Varied replication dynamics of HSV-1 were observed in different tissues or organs of the BALB/c mice in different groups.Therefore, different indexes should be adopted to evaluate different HSV-1 infection models.

Objective: To summarize the mid-term effect of modified extended Morrow procedure in patients with hypertrophic obstructive cardiomyopathy (HOCM) combining sub aortic valve obstruction and mid left ventricular obstruction. Methods: We studied 34 consecutive HOCM patients with sub aortic and midventricular obstruction who received modiifed extended Morrow procedure with extracorporeal circulation in our hospital from 1996-11 to 2015-01. Transthoracic echocardiography was conducted at pre-, post-operation and follow-up period to evaluate the changes of mid-ventricular gradient, subarctic gradient and each heart valve function. Results: The average follow-up time was (25.7 ± 14.9) months, 2 patients lost contact and no death occurred. In rest 32 patients, the mid ventricular gradient decreased from (60.3 ± 29.4) mmHg to (21.0 ± 19.8) mmHg, subaortic valve gradient decreased from (77.9 ± 26.2) mmHg to (11.6 ± 6.5) mmHg, the maximum ventricular septal thickness dropped from (25.2 ± 4.9) mm to (17.9 ± 7.2) mm, left atrial diameter reduced from (41.1 ± 7.8) mm to (37.6 ± 6.4) mm, left ventricular end-diastolic diameter increased from (39.8 ± 5.1) mm to (42.2 ± 4.3) mm, allP<0.05; there were 5 patients without obviously improved mid ventricular gradient because of insufifcient resection of septal myocardium in mid-ventricle. The post-operative NYHA classiifcation was improved,P<0.01, mitral valve regurgitation degree was decreased,P<0.01 and SAM phenomenon was disappeared. Complications included 3 (8.8%) patients of III atrio-ventricular block, 1 (2.9%) patient of re-admission due to poorly healed sternum combining pneumonia Conclusion: Modified extended Morrow procedure may relieve sub aortic valve and mid ventricular obstruction, therefore improve left ventricular diastolic function and prognosis in relevant patients.

OBJECTIVE: To investigate the differential expression of the sensitive and resistant relative proteins in human breast cancer tissue. METHODS: A drug sensitive group and a drug resistant group for chemotherapy in patients with breast cancer were selected through neoadjuvant. The differential protein expression in 2 groups was detected by proteomics techniques, and parts of differential proteins were identified by Western blot. RESULTS: There were 13 differential proteins in the 2 groups, in which the expression of 3 proteins was up-regulated and 10 down-regulated. Seven proteins were identified by Western blot. The expression of keratin type I cytoskeletal 19 (KIC19), thymidine phosphorylase (TYPH) was upregulated, and the expression of heat shock protein 27 (HSP27), keratin type I cytoskeletal 9 (KIC9), collagen alpha-2(VI) (CO6A2), vimentin (VIME), and actin cytoplasmic 1 (ACTB) was down-regulated in the drug resistant group. There was significant difference between the 2 groups (P<0.01). CONCLUSION The expression of KIC19 and TYPH may be correlated with drug resistance in patients with breast cancer, and HSP27, KIC9, CO6A2, VIME, and ACTB may be correlated with drug sensitivity.

Objective: To report the medium-long term survival rates of ventricular septal myectomy for treating the patients with hypertrophic obstructive cardiomyopathy and to analyze the predictive factors affecting the outcomes. Methods: A total of 655 consecutive patients who received ventricular septal myectomy in our hospital from 1984-10 to 2014-12 were retrospectively summarized. The cohort study was conducted with questionnaires by cardiovascular nurses. Result: The operative mortality was 1.4% (9/655). The mean follow-up time was (30.8 ± 30.9, from 3 to 213) months, there were 52/646 (7.9%) patients lost contact and 583 patients having NYHA classification at I or II during that period. The overall survival rates for 1 year, 5-year and 8-year were 98.3%, 90.5% and 88.3% respectively. There were 80 patients suffered from end point events including HCM-related death, heart transplantation, repeated myectomy, permanent pacemaker implantation and re-admission for ischemic stroke, tachyarrhythmia, myocardial ischemia or infarction, congestive heart failure. The end point events free survival rates for 1 year, 5-year and 8-year were 94.2%, 76.7% and 65.9% respectively. Multivariable Cox regression analysis presented that age>50 years (HR=2.16, 95% CI 1.36-3.46,P=0.001) and pre-operative atrial ifbrillation (FA) (HR=2.31, 95% CI 1.35-3.94,P=0.002) were the independent predictors for end point events occurrence. Conclusion: Ventricular septal myectomy may achieve good medium-long term survival rate with less adverse event in patients with hypertrophic obstructive cardiomyopathy. Elder than 50 years of age and with pre-operative FA were the independent predictors for adverse events occurrence.
