To genuinely orient our service towards the needs of patients, we modified the wards in our hospital, turning previous wards housing 8 to 10 patients each into medium-sized and small ones, with each one having a separate toilet, balcony, and air conditioner, meeting the diversified needs of patients, and attracting more patients to seek service at the hospital. As a result, in 2000, as compared with 1999, the number of emergency outpatients increased by 14.4%, the number of discharged patients increased by 16.2%, the average ratio of bed usage increased by 9.0%, the turnover rate of beds increased by 6.8%, the average length of stay dropped by 7.0%, income from outpatient service increased by 43.9%, the proportion of income from the sale of pharmaceuticals in the total business income dropped by 10.5%, and the annual business income increased by 18.9%.

Background and purpose:Zhongshan City is one of the areas with the highest NPC incidence worldwide and nationwide. Although its incidence rate had been analyzed thoroughly, but its mortality rate was not studied further until now. This study was to explore NPC mortality status in Zhongshan City from 1970 to 2010, and to provide scientiifc information for its control and prevention.Methods:NPC death data in Zhongshan City from 1970 to 2010 came from Zhongshan Cancer Registry Ofifce. Such indices as its death number, crude rate, age standardized rate (ASR) and truncated rate etc were calculated and analyzed. Results:There were 5 267 NPC death cases in Zhongshan City from 1970 to 2010, its crude world ASR and truncated rates were 11.03/105, 12.34/105 and 29.31/105 respectively. Its world ASRs increased before 1999 but no statistical signiifcance (P=0.64) and decreased thereafter with obvious statistical signiifcance (P=0.001). But overall, there were a decreasing trend for its ASRs (P=0.001) from 1970 to 2010 in Zhongshan City. Moreover, NPC mortality rate in male was remarkably higher than in female, the death peak age was 55-59 age group, and the different age groups were with different trends fro 1970 to 2010. Conclusion:Although with declining trend from 1970 to 2010, NPC mortality rate in Zhongshan City was at high level worldwide. It suggested that NPC control and prevention should be enhanced.

Objective To explore the expression of survivin gene in retinoblastoma (RB) and its relationship with the stages and histodifferentiation degree of RB and the expression of p53?bcl-2 proteins. Methods Expression of survivin, p53 and bcl-2 proteins in 38 RB conventional paraffin samples were detected with survivin, p53 and bcl-2 monoclonal antibodies respectively by immunohistochemical assay. The expression of survivin of normal retina in 6 control samples was observed. Results In 38 cases of RB, positive expression of survivin was found in 20 (52.6%); while none of the 6 normal retinal tissue expressed survivin, which had significant difference between the two group (P0.05). In 38 RB cases, positive expression of p53 was in 25 with the rate of 65.8%, and of bcl-2 in 18 with the rate of 47.4%. The positive-expressed rates were much higher in positive-expressed p53 and bcl-2 group than those in the negative-expressed p53 and bcl-2 group (P

0.05) except for 8 kHz. Air conduction thresholds were basically normal in children's simple type CSOM, whereas hearing loss during intermediate frequency and high frequency in adults with osteitis and cholesteatoma type was more severe than that in children.Conclusion Hearing-loss in children's CSOM was the same as adult patients, although course of disease was not long in children. Inner ear was not or mildly impaired in children's CSOM.

Objective To study the expression and its significance of Platelet-derived growth factor(PDGF) and Collagen type Ⅰ (Col- Ⅰ) mRNA in hepatic tissue in mice exposed to arsenic in drinking water. Methods Fifty mice were divided into control group, sodium arsenite group(iAs3+ group, 300 mg/L) and sodium arsenate group (iAs5+ group, 300mg/L) at random. The mice were sacrificed after 10 months for liver function test (ALT, AST and GLB examined by automatic biochemical analyzer) and pathologic examinations. Masson staining and immunohistochemical SABC methods were used. Through the result of Masson staining fibrosis semi-quantitative analysis of the fibrosis number was carried out in the per unit area. Using immuonhistochemical SABC methods, the expression of PDGF and Col- Ⅰ was detected. Results ①Serum ALT was statistically significant among control group [(36.67±3.51) U/L], iAs3+ group[(61.46±13.85) U/L] and iAs5+ group[(43.31±4.21) U/L, F= 6.56, P < 0.05], especially between the control and iAs3+ group (P < 0.05) ;Serum AST had a statistical significance among control group [(135.00 ± 20.42)U/L], iA3+ group [(510.86 ± 59.01)U/L] and iAs5+ group[(258.93 ± 22.40) U/L, F= 83.36, P < 0.05] ;Serum GLB had no statistical significance among control group [(20.86 ± 0.61)g/L], iAs3+ group [(26.94± 3.73)g/L] and iAs5+ group[(24.59 ± 5.27)g/L, F = 2.80, P < 0.05]. ②Masson staining revealed notable liver cell necrosis, regeneration, infiltration of inflammatory cells in portal area. Masson staining Semi-quantitative results showed significantly increasing size of fibrosis in model group. Compared with control group(0.069 ± 0.013) and iAs5+ group(0.143 ± 0.122), fiber hyperplasia of iAs3+ group(0.192 ± 0.108) had statistical significance (F = 1.91, P < 0.05). ③Immunohistochemistry results showed higher expression of PDGF in the portal area, sepetal and preisinus cells in model group. The heavy expression of Col- Ⅰ distributed in the surrounding of blood vessels and bile duet and along portal wall extensting to the liver in model group. Semi-quantitative results showed that PDGF among control group(202.79 ± 7.46), iAs3+ group(174.38 ± 7.71) and iAs5+ group(177.64 ± 7.81) had a statistical significance(F= 102.91, P < 0.05);Col-Ⅰ had a statistical significance among control group(200.11 ± 7.46), iAs3+ group (176.47±10.20) and iAs5+ group (177.378 ±7.948, F = 78.51, P < 0.05). Conclusions Exposed in oral drinking arsenic, mice can develop hepatic injury and hepatic fibrosis. The PDGF and Col-Ⅰ play significant effects on the process of hepatic fibrosis caused by oral drinking arsenic exposed mice.

At present, the research regarding repair of spinal cord mainly focuses on tissue engineering. Neural tissue engineering materials provide three-dimensional template for tissue regeneration and also environment for synthesis of extracellular matrix. This paper summarizes the types of nerve transplant materials and the research progress in application for treatment of spinal cord injury, so as to provide theoretical evidence for repair of spinal cord injury. But some problems exist in application of nerve cell scaffold materials for repair of spinal cord injury: poor mechanical properties lead to slow degradation speed, causing difficulties in tissue reconstruction with respect to velocity and in subsequent reconstruction of porous three-dimensional scaffold. In recent years, novel biomaterials with specific repair function have been made by the engineering method through combining the biological molecule with specific signal identification function and available materials, which is an advanced projeot in the current field of biomaterials.

The concentrations of borneol in the serum and brain tissue of rats were determined by gas chromatography. Using brain tissue as a relatively independent system, PHARMFIT and PCNONLIN softwares are applied for the kinetic analysis of the infracorporal process of borneol in order to find out and compare the pharmacokinetic characteristics of borneol in the brain and serum. The results showed that borneol was absorbed very rapidly in the gastrointestinal tract and readily permeates the blood-brain barrier into brain tissue. There was a higher specific value of borneol concentration in the brain and serum. Moreover, the half life of distribution phase of borneol in the brain was three times higher than that in the serum. But the constants of elimination rate of borneol in the brain and serum decreased simultaneously and parallelly, hence the accumulation of borneol in brain will not be found.
