A harmonious physician-patient relationship is closely correlated with hospital culture construction.This paper explores the correlation from the perspectives of roles in building up decent fame of hospitals,promoting the construction of medical ethics,cultivating a fine humanistic medical atmosphere,strengthening the social responsibility of hospitals,and further clarifies the important function of hospital culture construction in constructing a harmonious physician-patient relationship.

Objective: Sonodynamic therapy (SDT), using sono-sensitizer and ultrasound, is a new combined therapy for cancer treatment. The study used ultrasound to stimulate sono-sensitizer SonneLuxe, and study the tumor-killing effects of SDT on S-180 sarcoma in mice. Methods: The mice bearing S180 sarcoma were injected i. p. SonneLuxe 20 mg/kg. Six hours later, the tumor area was irradiated by 1.0 MHz ultrasound for 3 min. The mice were divided into three groups which were irradiated by ultrasound at intensity of 0.3 W/cm2, 0.6 W/cm2 and 1.2 W/cm2, respectively. The empty control, ultrasound-irradiated, and SonneLuxe-treated mice bearing S-180 sarcoma were used as different controls. The tumor size was recorded every 2 days and the tumor was weighted on the 15th day after treatment. Results: Ultrasound or SonneLuxe alone had no significant killing effect on S-180 sarcoma in mice. The proliferation of tumor was significant. SDT/SonneLuxe stimulated by ultrasound had significant inhibitory effect on the growth of S-180 sarcoma. The efficacy of SDT was enhanced accompanied with the increase in the ultrasound intensity. The adverse reaction such as photosensitive dermatitis was not observed. Conclusion: SonneLuxe/SDT had significant killing effect on S-180 sarcoma in mice. It may be a promising modality for cancer therapy.

Objective To measure Tei index in patients with idiopathic or ischemia dilated cardiomyopathy, and to evaluate its correlation with other conventional indexes of echocardiography of left ventricular(LV) function,and its applicability in assessing cardiopulmonary exercise capacity in those patients.Methods Seventy consecutive patients (53?14 years) with heart failure(New York Heart Association [NYHA] class, Ⅱ to IV) who had received echocardiographic diagnosis, and believed to be suffering from dilated or ischemia cardiomyopathy were studied. Echocardiography were performed; LV volume as well as ejection fraction were measured from the apical view of the two-dimensional echocardiogram using a modified Simpson’s rule algorithm in all patients. The following variables: peak early transmitral filling velocity (E), late transmitral filling velocity (A), their ratio (E/A), the deceleration time of E (DT), and Tei index were measured by spectral Doppler echocardiography. Furthermore, all patients underwent a cardiopulmonary exercise using 6min walk test. Results Advanced NYHA class was associated with higher Tei index values. A positive correlation was found between Tei index and early /late filling velocity ratio, while a negative correlation was found between Tei index and A wave, E wave, DT, and LV EF. Tei index showed no correlation with heart rate, blood pressure or age. Compared with the parameters of left ventricular function Tei index had a closer relation to the distance of 6min walk. Stepwise regression analysis revealed that the Tei index and the late LV filling velocity were the only independent predictors for cardiopulmonary exercise capacity.Conclusion Tei index correlates inversely with LV performance and reflects disease severity, which is a useful complimentary variable in the assessment of cardiopulmonary exercise performance in patients with heart failure.

Objective To determine the mechanism of nitric oxide synthase(NOS) and prostacyclin(PGI2) acting on splanchnic hyperdynamic circulation of portal hypertention(PHT). Methods Ninety-six Sprague-Dawley rats were divided into three groups, namely, intrahepatic portal hypertension(IHPH, n=31), prehepatic portal hypertension(PHPH, n=33) and sham-operated controls(SO, n=32). Animals of each group were received indomethacin(INDO) either on a short term or long term with saline as control. Portal venous pressure, together with the concentration of nitric oxide (NO) and PGI2 in serum was measured. The constitutive nitric oxide synthase(cNOS)and inducible nitric oxide synthase(iNOS)activity in the abdominal aorta and small intestine of these rats were detrmined by spectrophotometry method. RT-PCR was performed to measure the levels of iNOS and cNOS mRNA in the arteries and guts mentioned above. Results Although INDO decreased the concentration of PGI2 in serum, the long-term INDO-treated group restored splanchnic hyperdynamic circulation in both IHPH and PHPH rats, concomitant with enhanced expression of iNOS and concentration of NO(P0.05). Conclusion Overproduction of NO inducing hemodynamic abnormalities of PHT is synthesized principally by increase of iNOS. There may be a possible interaction between PGI2 and NO in hyperhemodynamics of PHT, while PGI2 may not be a mediator in the formation and development of hyperdynamic circulatory state.

Thoracic vascular ultrasound was used to evaluate left internal mammary artery to left anterior descending artery (LAD) bypass (LIMA) blood flow pattern in CABG patients. A transthoracic vascular transducer (5～10 MHz) was placed in the second rib space left to the sternum. Doppler spectrum was obtained under 2 D color Doppler image guide. Systolic and diastolic flow was analysed as systolic peak velocity (SPV), systolic velocity time integrate (SVTI), diastolic peak velocity (DPV) and diastolic velocity time integrate (DVTI). Successful examination was done in 106 patients ( 106/110, 94% ) , In patients with patent LIMA, Doppler spectrum showed a notable diastolic flow spectrum. The results of this study suggested that trans thoracic echocardiographic examination could provide avaluable blood flow information. A notable diastolic flow spectrum can be taken as a sign of satisfactory LIMA coronary diastolic myocardium perfusion.

High mobility group box-1 protein (HMGB1) has recently been shown as a crucial late mediator of inflammation and sepsis, and is involved in mediating multi-organ functional lesions, including acute lung, liver, and intestine injuries. As a delayed inflammatory cytokine, HMGB1 provides a wider therapeutic time window for clinical intervention. HMGB1 has been proven to be a promising therapeutic target to prevent the development of multiple organ dysfunction syndrome in experimental models of severe sepsis. The pharmacological strategies include neutralization of antibodies or specific HMGB1 antagonists, suppression of HMGB1 secretion (ethyl pyruvate, agonists for alpha7-nicotinic acetylcholine receptors), and down-regulation of HMGB1 expression (sodium butyrate, signaling inhibitors for Janus kinase/signal transducer and activator of transcription).

OBJECTIVETo systematically evaluate prostate health index (PHI) in predicting the results of prostate biopsy in the diagnosis of prostate cancer.

METHODSWe retrieved the literature relevant to the value of PHI in predicting prostate cancer at prostate biopsy published from the inception to February 2014 in the databanks of PubMed (1966 - 2014), CNKI (1982 - 2014), VIP (1989 - 2014), and Cochrane Library (1999 - 2014). According to the inclusion and exclusion criteria and retrieval strategies, we extracted the data, evaluated the quality of the included literature, and performed meta-analysis using the Meta-Disc 1.4 software.

RESULTSTotally, 64 articles were identified, of which 52 were excluded and 12 included with 1 430 cases of prostate cancer and 2 159 normal or BPH controls. There was heterogeneity among the included studies. Based on the random effect model, in predicting the results of prostate biopsy in the diagnosis of prostate cancer, serum PHI exhibited a pooled sensitivity of 55.1% (95% CI: 0.525 - 0.577), a pooled specificity of 71.5% (95% CI: 0.695 - 0.734), a positive likelihood ratio (P-LR) of 2.379 (95% CI: 1.922 - 2.943), a negative likelihood ratio (N-LR) of 0.515 (95% CI: 0.428 - 0.619), a diagnosis odds ratio (DOR) of 5.268 (95% CI: 3.870 - 7.170), a summary receiver operating characteristic curve--area under the curve (SROC AUC) of 0.7578, and a Q * index of 0.6999.

CONCLUSIONSerum PHI plays a role of auxiliary diagnosis in detecting prostate cancer and can be used in the prediction of the results of prostate biopsy.
