Objective To compare the effect of right ventricular outflow tract (RVOT) and right ventricular apex (RVA) pacing on ventricular systolic synchrony using gated blood pool SPECT (GBPS).Methods A total of 50 patients implanted with pacemaker due to high degree or complete atria-ventricular block were enrolled in the study. Twenty-three patients were RVOT paced ( Group A, n = 23) and 27 were RVA paced (Group B, n=27). Twenty-four patients with malignancy, normal echocardiographic findings and no history of cardiac diseases were scheduled for pre-chemotherapy evaluation of cardiac structure and function and were enrolled as control group ( Group C, n = 24). All patients underwent GBPS imaging and the values of phase angle (PS), mean phase of each wall, standard deviation (SD) of mean phase of each wall, lateral-septal motion delay of left ventricle ( LV Sep-Lat Delay), septal-right ventricular (RV) delay of LV ( LV Sep-RV Delay) and LV-RV Delay were acquired. The parameters of ventricular systolic synchrony among the three groups were compared using one-way ANOVA. Results The mean phase of LV lateral wall in Groups A and B were significantly higher than that in Group C: Group A (120.50 ±40.58) ms; Group B (103.23±28.34) ms; Group C (84.63 ±22.38) ms (F=7.72, P ＜0.05). There was no significant difference between Groups A and B ( t = 1.30, P ＞ 0.05 ). The mean phase of RV in Group A was significantly larger than those in Groups B and C: Group A ( 137.05 ± 39.27) ms, Group B ( 100.85 ± 23.79) ms,Group C (59. 13 ±30.52) ms (F=35.55, P＜0.05). PS, SD and LV Sep-Lat Delay in Groups A and B were significantly higher than those in Group C: (85.73 ± 12.00)°vs (89.85 ± 15.61 )°vs (58.95 ±9.87)°, (27.68±10.66) ms vs (26.15 ±13.02) ms vs (15.63 ±8.35) ms, (25.06±34.23) ms vs (2. 62 ± 60. 31 ) ms vs ( - 23.66 ± 31.39) ms, F = 41.54,8.55,6.81, all P ＜ 0.01 ), however, there was no significant difference between Groups A and B ( t = 0. 68, 0.68, 1.30, all P ＞ 0.05 ). LV Sep-RV Delay and LV-RV Delay were significantly different among the three groups ( LV Sep-RV Delay: Group A (57.60 ±56.77) ms, Group B (6.36 ±61.88) ms, Group C ( -41.89 ±35.78) ms; LV-RV Delay:Group A (47.36 ±42.59) ms, Group B ( 3.08 ± 38.81 ) ms Group C ( - 26.50 ± 20.99 ) ms, F = 20. 32,25.38, both P ＜ 0.01 ). Conclusion Both RVA and RVOT pacing increase the segmental phases detected by GBPS, causing inter- and intra- ventricular asynchrony compared with patients without pacemakers.

Objective To investigate in vitro activity of antimicrobial agents against Enterococcus spp . isolated from clinic specimens in a hospital.Methods 188 Enterococcus spp . isolates from specimens sent by clinic depart-ments in June 2013-July 2014 were identified and performed antimicrobial susceptibility testing.Results Of 188 En-terococcus spp . isolates,119 were Enterococcus faecium (E.faecium),60 were E.faecalis ,and 9 were E.avium, these strains were mainly isolated from urine (34.57%)and blood specimens (19.15% ).No daptomycin and linezolid-resistant strain was detected;resistant rates of E.faecium to vancomycin was 1 .68%,to penicillin, ampicillin,high concentration gentamycin,erythromycin,and levofloxacin were all > 70%;except tetracycline, resistant rates of E.faecalis to the other antimicrobial agents were all lower than E.faecium,resistant rates of E. faecalis to penicillin and ampicillin were 16.67% and 13.33% respectively.Conclusion Daptomycin has high activity against Enterococcus spp . in this hospital.

Background Placement of an orbital implant is a main way to prevent orbital atrophy with aging.But its mechanism is under clear.Researchs showed that bone growth factors play important role during the development and repair of bone,especially transforming growth factor-β1(TGF-β1).Objective Present study was to investigate the expression of TGF-β1 protein in orbital bone after enucleation or enucleation with placement of an orbital implant and its function in the mechanisms of preventing and treating the orbital malformed development after enucleation with placement of an orbital implant.Methods Twenty-one age- and weight-matched New Zealand white young rabbits were randomly divided into the enucleation,implant and control groups,and each group including seven rabbits.Eyeball nucleation surgery was performed in the left eyes of 7 1-month-old rabbits,and a spherical orbital implant was inserted after enucleation of the left in matched rabbits in implant group.The left eye of normal rabbits served as controls.The rabbits were sacrificed in 1 month after surgery.The expression of TGF-β1 protein in the left orbital bone was detected using enzyme immunoassay and FITC labelling immunoassay technique in the sections of zygomatic bones.The content of TGF-β1 protein in the left orbital bone tissue was measured by ELISA method.This use of animals complied with the Regulations for the Administration of Affair Concerning Experimental Animals by State Science and Technology Commission.Results The height and width of orbital in enucleation group were significantly lower than those of implant and normal control groups(height:P=0.00,P=0.00;width:P =0.00,P=0.00).The positive bone cells of both enzyme immunoassay and FITC staining were increased in the implant and control groups in comparison with enucleation group,but the positive response intensity for TGF-β1 was resembled between implant group and control group.ELISA result revealed that the content of TGF-β1 protein in bone tissue was significantly lower in the enucleation group than in implant and control groups(P=0.00,P=0.00).The expression and content of TGF-β1 protein in bone tissue is similar between the implant group and the control group(P=0.41). Conclusion The experiment results indicate that TGF-β1 protein participate in the orbital development.TGF-β1 played important role in the prevention and treatment of enucleation-induced orbital malformation in the eye with placement of an orbital implant.

OBJECTIVETo observe the effects of Jinshuibao Capsule (JC) combined losartan potassium on some indices of early renal damage of hypertension patients of yin and yang deficiency syndrome (YYDS), such as levels of serum cystatin C (Cys C), beta2-microglobulin (beta2-MG), hypersensitive C-reactive protein (hs-CRP), uric acid (UA), blood pressure, blood lipids, and fasting blood glucose (FBG), and to explore their protective effects on early renal damage of hypertension patients and on the metabolisms of blood lipids and blood glucose.

METHODSTotally 106 hypertension patients of YYDS were randomly assigned to two groups, 53 patients in the control group (treated by losartan potassium) and 53 patients in the treatment group (treated by JC + losartan potassium). The treatment lasted for 16 weeks. The serum changes of UA, Cys C, beta2-MG, hs-CRP, blood lipids [including total cholesterol (TC), triglyceride (TG), low density lipoprotein cholesterol (LDL-C), and high density lipoprotein cholesterol (HDL-C)], and FBG levels were measured to evaluate the renal protective effects and to assess their effect on the metabolisms of blood lipids and blood glucose.

RESULTSCompared with before treatment in the same group, the systolic blood pressure (SBP) decreased in the two groups after treatment, showing statistical difference (P < 0.05, P < 0.01), but there was no statistical difference between the two groups (P > 0.05). The diastolic blood pressure (DBP) was not obviously declined in the two groups after treatment, showing no statistical difference. Compared with before treatment in the same group, the LDL-C level decreased obviously after treatment in the control group. But there was no obvious change in FBG, TC, HDL-C, and TG in the control group, showing no statistical difference when compared with before treatment (P < 0.05). The FBG, TC, and LDL-C obviously decreased in the treatment group more obviously after treatment than before treatment, showing statistical difference (P < 0.05, P < 0.01). There was no statistical difference when compared with the control group after treatment (P > 0.05). Compared with before treatment in the same group, the levels of UA, Cys C, beta2-MG, and hs-CRP all decreased in the two groups, showing statistical difference (P < 0.05, P < 0.01). The SCr level decreased in the treatment group more obviously after treatment than before treatment, showing statistical difference (P < 0.05). Compared with the control group after treatment, the levels of Cys C, beta2-MG, and hs-CRP decreased more obviously after treatment in the treatment group, showing statistical difference (P < 0.05).

CONCLUSIONSJC combined losartan potassium showed better effects in treating early renal damage of hypertension patients of YYDS. They could protect and stabilize the renal functions more effectively. JC could regulate blood lipids and blood glucose.

Objective To analyze the clinical characteristics of auditory neuropathy under pure tone audiometry and acoustic immitance examination.Methods Seventeen patients (32 ears) diagnosed as having auditory neuropathy were examined for audiology features by pure tone audiometry and acoustic immitance.Results Bilateral and symmetrical hearing loss was found in 15 patients and low-frequency sensorineural hearing loss was noted in 26 ears.Seventeen ears with a course of disease less than 5 years presented light or moderate dysaudia,and those with more than 5 years presented grave loss of aural comprehension.16 patients (31 ears) in the acoustic immitance examination showed type A tympanogram,and absence of stapedius muscle reflex was found in 15 patients (30 ears).The threshold of acoustic stapedius reflex increased in 2 patients (2 ears).Conclusion Auditory neuropathy primarily presents bilateral and symmetrical hearing loss,low-frequency hearing loss at the initial stage and total-frequency hearing loss finally,absence of stapedius muscle reflex and type A tympanogram,and absence of loudness recruitment phenomenon.

OBJECTIVETo assess postoperative effects of microelectrode-guided posteroventral pallidotomy (PVP) for Parkinson's disease.

METHODSIntraoperative microelectrode recordings and microstimulation were used to explore the globus pallidus to performance of posteroventral pallidotomy in 48 patients with Parkinson's disease (47 unilateral and 1 bilateral). Assessment was made at baseline preoperatively and at 6 months intervals postoperatively, with unified Parkinson's disease rating scale (UPDRS).

RESULTSAll patients were significantly improved on the limbs contralateral to the lesion side 6 - 34 months after operation (mean 24 months). The improvement was seen in the 'on' or 'off' state: UPDRS scores with patients on levodopa were improved by an average of 28.7%, while off medication scores showed reductions (47.6%) at 24 months. There were no deaths and no visual complications, but there were 4 patients (8.3%) of a delayed contralateral limbs dystonia after pallidotomy.

CONCLUSIONSThe techniques of microelectrode recording and microstimulation indicate the location of the internal capsule and optic tract, which allow easy identification of these structure and facilitate PVP target in conjunction with radiofrequency microelectrode stimulation.

OBJECTIVESTo discuss the correlation of C-reactive protein (CRP) concentration in the EPS of chronic prostatitis (CP) patients with CP types, WBC count in EPS, lecithin corpuscles (LLZXT) and chronic prostatitis symptom index (CPSI).

METHODSAccording to the NIH classification standard, 196 cases of CP were diagnosed by the pro and post massage test (PPMT) and EPS routine, of which 68 were chronic bacterial prostatitis (Type II ), 76 inflammatory chronic non-bacterial prostatitis/chronic pelvic pain syndrome (Type III A) and 52 non-inflammatory chronic non-bacterial prostatitis/chronic pain syndrome (Type III B). Another 50 healthy volunteers were enrolled as normal controls. The CRP concentration in the EPS of all the patients was determined by immunoturbidimetry and 196 groups of data were obtained.

RESULTSThe average concentration of CRP was significantly higher in the CP group ( [2.945 +/- 1.996] mg/L) than in the control ( [1.101 +/- 0.440] mg/L) (P < 0. 01) , and it decreased progressively from the Type II to Type III A and Type III B group, with statistical difference between Type III B and Type II or Type III A (P < 0. 01 ), but not between Type II and Type III A (P = 0.058). The CRP concentration was correlated negatively with LLZXT (r = -0.33, P < 0.01) and positively with WBC count (r = 0.63, P < 0.01) and the score on the first 6 items of CPSI (r = 0. 28, P < 0. 01).

CONCLUSIONThe CRP concentration in EPS, with its significant role in the pathogenesis of CP, may serve as a basis for the diagnosis and classification of CP as well as an objective index for assessing the therapeutic effect on the disease.
