The author explained in the first place what was meant by the modernization of hospitals. In his view, modernization of a hospital includes modernization of its buildings and modernization of its science and technology. The former refers to the modernization of a hospital's main buildings and supporting facilities and modernization of its environment, the style of which should be in line with the main buildings. These manifest as having functional, ecological, humane, intelligent and artistic features. The latter refers to the degree of bit and modernization seen in the ideas and quality of the managers. Then the author gave an account of how the hospital he works with put the above ideas into practice during the second phase of its construction.

Taking the 8-year management practice of Sanjiu Brain Hospital of Guangdong since its founding as a case, the paper gives an account of how the hospital managed to grow by leaps and bounds. The steps taken include: guiding decision-making with innovations in thought and blazing new trails in such aspects as growth strategies, leadership structure, system of operation, quality control, nursing management, service skills, marketing management, hospital culture, and logistics management. The paper argues that innovation is the soul and driving force of hospital management and reform and that daring to and knowing how to make innovations are indispensable to enhancing the core competitiveness of the hospital and promoting its fast and sustainable growth.

Carotid atherosclerosis is a major cause of ischemie stroke. Understanding the compositions of carotid plaque arid preventing plaque rupture are of importance to reduce the risk of ischemic stroke. Magnetic resornance imaging (MRI) is noninvasive, highly reproducible, does not involve exposure to ionizing radiation. It is one of the most potential imaging tools for carotid atherosclerotic plaques. This article reviews the application of MRI in the imaging of carotid atherosclerotic plaques.

ObjectiveTo study the relationship between Borna disease virus (BDV) and the human viral encephalitis.MethodsThe P24 fragment of BDV RNA in peripheral blood mononuclear cells (PBMC) from 59 patients with viral encephalitis diagnosed clinically, and 112 healthy donors were examined by fluorescence quantitative nested reverse transcriptase polymerase chain reaction (FQ-nRT-PCR).ResultsThere were 3 positive of BDV P24 fragment in 59 patients with viral encephalitis, and no positive in blood donors. The positive rate of BDV p24 in PBMC in viral encephalitis (5.08%) was higher significantly than that in blood donors (P

BACKGROUND:In terms of the histocompatibility, immune rejection and scar formation after repair, acel ular nerve al ograft is closer to autologous nerve cel s. At present, hyaluronic acid has been applied for autologous peripheral nerve repair;however, research on the nerve al ograft is rarely reported.
OBJECTIVE:To explore the effect of hyaluronic acid on the anastomotic scar in acel ular nerve al ograft repair of rat sciatic nerve defect.
METHODS:Thirty-six Sprague-Dawley rats were randomly divided into three groups (n=12 per group). The rat model of nerve defect of 10 mm was established by cutting the sciatic nerve of the left hind leg and then given nerve al ograft combined with the injection of hyaluronic acid at anastomosis (experimental group), only nerve al ograft (control group) and autologous nerve graft (nerve autograft group), respectively. Afterwards, the healing of the proximal anastomosis was observed and scar components were assessed.
RESULTS AND CONCLUSION:Gross observations showed that the rat skin and muscle fascia had no significant differences in healing among groups, while the surrounding tissue adhesion in the experimental group was milder than that in the control group (P<0.05). Masson staining found that col agen deposition in the epinerium could be observed in each group. In the experimental group, a smal amount of col agen fibers arranged orderly in the epineurium;in the control group numerous col agen fibers accumulated and arranged irregularly;in the nerve autograft group, sparse epineurial col agen fibers appeared in an order arrangement. The gray value of col agen type I in the experimental group was higher than that in the control group (P<0.05), while the gray value of col agen type III was lower than that in the control group (P<0.05). No significant differences were found in the sum gray values of col agen type I and III among groups (P>0.05). These findings indicate that in the peripheral nerve repair, hyaluronic acid abrogates the scar formation by increasing the deposition of col agen type III and reducing the deposition of col agen type I.

Objective To investigate the chemical constituents of Wedelia trilobata.Methods The chemical constituents were separated by chromatography and their structures were determined by physico-chemical constants and spectral analyses.Results Eleven compounds were isolated and identified as grandiflorenic acid(1),1?-acetoxy-6?,9?-dihydroxy-4,10?-dimethyl-5?H,7?H,8?H-endesm-3-en-8,12-olide(2),1?-acetoxy-4?-hydroxy-6?-isobutyryloxy-9?-isovaleryloxyprostatolide(3),16?-hydroxy-ent-kauran-19-oic acid(4),(3R,4R,6R)-3,4-dihydroxy-1-menthene(5),trilobolide-6-O-isobutyrate(6),1?-acetoxy-4?,9?-dihydroxy-6?-isobutyroxyprostatolide(7),16?,17-dihydroxy-ent-kauran-19-oic acid(8),daucosterol(9),protocatechualdehyde(10),and caffeic acid(11).Conclusion All the compounds are isolated from W.trilobata for the first time except compounds 6 and 7.Compounds 2 and 3 are new sesquiterpene lactones,named as trilobolide A and 1?-acetoxy-4?-hydroxy-6?-isobutyryloxy-9?-isovaleryloxyprostatolide,respectively.

Objective To investigate the appropriate surgical procedure for unilateral papillary thyroid microcarcinoma (PTMC).Methods Clinical data of 323 patients with unilateral PTMC in Cancer Hospital of Chinese Academy of Medical Sciences from 1999-2007 were retrospectively studied.Survival outcomes and prognostic factors were analyzed.Results After a median follow-up of 102 (range,12-188) months,the 10-year overall and disease-specific survival was 95.3％ and 98.9％.The 10-year recurrence-free survival was 85.5％.The 10-year cumulative recurrence rate of residue glands was 6.5％.Capsular invasion,pT stage and clinical stage were significant predictive factors for recurrence of residue glands (all P ＜ 0.05).Cox regression multivariate analysis showed that pT stage (HR 2.153,95％ CI 1.231-3.767,P =0.007) was independent predictive factor.Of the 311 patients treated with non-total thyroidectomy,the 10-year cumulative recurrence rate of residue glands was 6.8％ Conclusions Unilateral PTMC has a good prognosis and hemithyroidectomy (lobectomy and isthmusectomy) is an appropriate surgical pattern.Extrathyroidal extension is a significant predictor for recurrence.

Objective:To explore the efficacy and safety of amisulpiride at low dosage combined with clozapine in the treatment of refractory schizophrenia. Methods:Totally 160 patients with refractory schizophrenia were chosen from the psychiatric department of 4 hospitals during January to September in 2014 and randomly divided into the observation group and the control group with 80 cases in each. The patients were treated with clozapine plus amisupiride or clozapine plus placebo for 12 weeks. The positive and negative syn-drome scale ( PANSS) and treatment emergent side effect scale ( TESS) was used to respectively evaluate the efficacy and the adverse effects. Results:At the weekend of the 4th, 8th and 12th week after the treatment, the clinical efficacy in the observation group was sig-nificantly better than that in the control group (all P<0. 05). The total and every factors scores of PANSS after the treatment were sig-nificantly lower than those before the treatment in both groups ( P<0. 01), and the decrease in the observation group was more signifi-cant than that in the control group (P<0. 05 or P<0. 01). There was no significant difference in the incidence of adverse effects be-tween the two groups (P>0. 05). Conclusion:Amisulpiride at low dosage combined with clozapine can significantly improve the effi-cacy in the treatment of refractory schizophrenia without added adverse effects.

Objective To explore the different expression of NF-κB in both K562 and its multidrug resistant cell line K562/A02 and discuss the mechanism of muhidrug resistance(MDR). Methods To detect the growing feature of the cells. Flow cytometry was used to analys the difference between the distribution profile of K562/S and K562/A02 cell. MTT colorimetry was used to determine the cytotoxic effect of adramycin, and expression of mdrl gene was detected by semi-quantitative reverse transcriptase poly-merase chain reaction (RT-PCR) in K562 and K562/A02 cells. FACS was used to determine the expression and function of glycoprotein (P-gp) on the cell membrane. Western blotting was used to determine the NF-κB p65protein in nueleus. Results There was a difference between K562 and K562/A02 cells growed in a halfadherent way rather than suspending ones, there were increases in the percentage number of cells at G0/G1 and S phases(P ＜0.05). This was mirrored by a decreasing number of cells within the G2/M phase(P＜0.05). Butthere was no difference in apoptosis rate(P ＞0.05). mdr1 mRNA was detected in K562/A02 cells, in which the expression P-gp was much higher [(94.17±0.89)%:(1.41 ±O.491)%]. NF-κB p65 protein in nucleus was overexpressed in K562/A02 cells. Conclusion The activation of NF-κB signaling pathway may attribute to the formation of MDR in K562/A02 cells.

Objective To investigate the efficacy of endovascular stenting complicating other craniocervical artery stenosis (OCAS) in patients with atherosclerotic subclavian artery stenosis/occlusion (SASO).Methods The clinical data of receiving endovascular stenting therapy in patients with atherosclerotic SASO were analyzed retrospectively,including demographic characteristics,vascular risk factors,complicating OCAS,as well as stenting for SASO and follow-up results.Results A total of 65 patients with SASO were included in the study,47 of them were males and 18 were females (mean age of 64 ± 9 years).Forty-six patients (70.8％ ) complicated OCAS.The overall technical success rate was 95.4％,in which the patients with stenosis (n =58) were 98.1％ and those with complete occlusion (n =7) were 71.4％.The complications occurred in 4 patients.There were no intervention-related serious stroke and death.Mean follow-up was 24 ± 19 months,6 patients with restenosis and 10 with clinically relevant events were found.They mainly occurred in patients with OCAS.The first angioplasty patency rates were 94.5％,81.8％ and 81.8％,respectively at 12 and 24 months after procedure and at the end of follow-up.The survival rates of no clinically relevant events were 92.9％,74.6％ and 68.3％,respectively.Conclusions Endovascular stenting can safely and effectively treat the SASO patients complicating OCAS.Its overall clinical outcome may be affected to some extent by OCAS.
