Objective To understand the current economical operation of public hospitals in Hubei province and its effect on their public welfare performance. Methods To collect data in field survey and to analyze the current economic situation of such hospitals in the province based on relevant statistics.Results Financial revenue and expenditure of these hospitals keep rising and achieving a balance in general; for the insufficient government financial subsidy, 90% of the revenue of such hospitals come from their medical services and drugs sold; the per capita revenue of these public hospitals maintains a yearly rising trend; their asset-liability ratio was relatively high. Conclusions The public welfare performance of these hospitals tends to be impeded by the reform on the macro economic system and health policy changes, on top of the attraction of economic interests. Improving the government subsidy mechanism for public hospitals and standardizing the financial management mechanism of public hospitals.

Objective To observe different effects of cyclic and continuous nutrition infusion on serum nutritional indicators, peripheral white blood cell counts (WBC), arterial partial pressure of oxygen (PaO2), arterial partial pressure of carbon dioxide (PaCO2) and acute physiology and chronic health evaluation Ⅲ (APACHE Ⅲ ) score in patients with mechanical ventilated respiratory failure (MVRF).Methods A cross-over and self-controlled trial was conducted in 48 patients with MVRF treated in a medical intensive care unit during December 2006 to June 2009, and continuous nutrition (group A) and cyclic nutrition (group B) were infused respectively for patients of the two groups.Serum levels of albumin (ALB), pre-albumin (PA), transferrin (TR), PaO2, PaCO2, WBC and APACHE Ⅲ score were measured for the patients with 24-hour continuous nutrition (group A) and 16-hour cyclic nutrition (group B)infusion.Effects of the two nutritional therapies were compared.Results After nutrition infusion, serum levels of ALB, PA and TR were (34±3)g/L, (196±28)mg/L and (2.1±0.3 ) g/L in group A, and (35 ±4) g/L, (198 ±25) mg/L and (2.0 ±0.4) g/L in group B, respectively; and PaO2 and PaCO2levels were (92 ± 12) mm Hg ( 1 mm Hg =0.133 kPa) and (42 ± 10) mm Hg in group A, and (91 ±9)mm Hg and (42 ± 10) mm Hg in group B, respectively.WBC and APACHE Ⅲ score were ( 11.8 ± 1.7) ×109/L and 38 ±7 in group A, and ( 12.6 ± 1.2) × 109/L and 40 ±6 in group B, respectively.Significant difference in serum levels of PA and TR was found between the two groups (PPA =0.019 and PTR =0.013),while there was no significant difference in other indictors between the two groups.Conclusions 24-hour continuous nutrition infusion for patients with MVRF can obviously improve their serum levels of PA and TR,but has no effect on serum level of ALB, PaO2, WBC and APACHE Ⅲ score in critical ill patients, as compared to those with 16-hour cyclic nutrition infusion.

Objective To investigate the effect of surgical trauma on the expression of COX-2 and PGE2in the hippocampus in aged rats. Methods Forty-five 18-month-old male SD rats weighing 500-600 g were randomly divided into 3 groups (n = 15 each): group Ⅰ control (group C); group Ⅱ anesthesia (group A) and group Ⅲ surgery + anesthesia (group S). Anesthesia was induced by intraperitoneal 1% pentobarbital sodium 50 mg/kg in group A and S. The animals underwent appendectomy and splenectomy under anesthesia in group S.Cognitive function was assessed by open field test and Y-mase test on the 1st, 3rd and 7th day after anesthesia and surgery (T1-3). The animals were sacrificed after behavior tests at T1.2.3 and the hippocampi were removed for determination of the expression of COX-2 mRNA (by RT-PCR) and PGE2 content (by ELISA). Results The time the animal spent in the central square was significantly prolonged, the number of crossing grid and standing on the back legs and the number of right response were decreased, the total reaction time was prolonged and the COX-2mRNA expression at T1 and PGE2 content in the hippocampus were increased at T1,2 in group S as compared with group C and A. There was no significant difference in the variables mentioned above between group C and A. Conclusion Surgical trauma can induce early postoperative cognitive dysfunction through up-regulation of COX-2 mRNA expression and by increasing PGE2 content in the hippocampus in aged rats.

In order to enhance the specificity of TNF-α monoclonal antibody to inflamed site, a bispecific antibody BsDb that targets TNF-α and the extra-domain B (ED-B) of fibronectin (FN) was constructed by covalently linking the anti-TNF-α single chain Fv antibody (TNF-scFv) and the anti-ED-B scFv L19 via a flexible peptide linker deriving from human serum albumin (HSA). ED-B is an antigen specifically expressed at the inflamed site. BsDb is expressed in E. coli, identified by immunoblot, and purified with affinity chromatography. This was followed by further examination of its bioactivities and pharmacokinetics. We demonstrated that BsDb retained the immunoreactivity of its original antibodies as it could simultaneously bind to TNF-α and ED-B and neutralize the biological action of TNF-α. In the collagen-induced arthritis mice model, BsDb selectively accumulate in the inflamed joint with a maximal uptake of (12.2 ± 1.50)% ID/g in a single inflamed paw and retain in the inflamed paw for at least 72 h. In contrast, BsDb showed a short serum half-life of (0.50 ± 0.05) h and a rapid clearance from normal tissues. The findings reported herein indicate that BsDb has good specificity to the inflamed site and low toxicity to normal tissues. BsDb is therefore likely to have greater clinical applications in the treatment of rheumatoid arthritis and other autoimmune diseases. This laid a stable basis for its preclinical study.

Objective:To evaluate the role of miR-146a in hippocampal inflammatory responses in postoperative cognitive dysfunction (POCD) in mice.Methods:One hundred and sixty clean-grade male C57BL/6 mice, aged 12-16 weeks, weighing 22-28 g, were divided into 5 groups ( n=32 each) using a random number table method: control group (group C), group POCD, miR-146a agomir group (group Ag), miR-146a antagomir group (group At) and negative control group (group NC). The mice were subjected to an intramedullary fixation for tibial fracture under 1.5% isoflurane anesthesia to establish POCD model.At 2 days before operation, miR-146a agomir 0.5 nmol (0.1 nmol/μl) was injected into bilateral hippocampi in group Ag, miR-146a antagomir 2.5 nmol (0.5 nmol/μl) was injected in group At, miR-146a negative control solution 2.5 nmol (0.5 nmol/μl) was given in group NC, and the animals in group C did not receive any treatment.At 1 day before operation and at 1, 3 and 7 days after operation, open-field test was performed to evaluate spontaneous motor activity, and contextual fear conditioning test was performed to evaluate cognitive ability 15 min later.At 1 and 3 days after operation, the animals were sacrificed and hippocampi was removed for determination of expression of CD11b (a marker for activation of microglia) in hippocampal CA1 region by immunofluorescence staining.At 6, 12 and 24 h after operation, the expression of miR-146a was detected by quantitative real-time polymerase chain reaction, the expression of interleukin-1 receptor-associated kinase 1 (IRAK1), tumor necrosis factor receptor-associated factor 6 (TRAF6), nuclear factor kappa B p65 (NF-κB p65) and tumor necrosis factor-alpha (TNF-α) was determined by Western blot and interleukin-1beta (IL-1β) and IL-6 contents were determined by enzyme-linked immunosorbent assay. Results:There was no significant difference in the total exploring distance in the open-field test or percentage of freezing time in tone-fear conditioning test at each time point among the five groups( P>0.05). Compared with group C, the percentage of freezing time in the contextual fear conditioning test was significantly decreased at 1, 3 and 7 days after operation, the expression of CD11b at 1 and 3 days after surgery and expression of miR-146a, IRAK1, TRAF6, NF-κB p65 and TNF-α were up-regulated and the contents of IL-1 β and IL-6 were increased at 6, 12 and 24 h after operation in group POCD ( P<0.05). Compared with group NC, the percentage of freezing time in the contextual fear conditioning test was significantly increased at 1, 3 and 7 days after operation, and the expression of CD11b was down-regulated at 1 and 3 days after surgery, and the expression of miR-146a, IRAK1, TRAF6, NF-κB p65 and TNF-α was up-regulated and IL-1β and IL-6 contents were decreased at 6, 12 and 24 h after operation in group Ag, and the percentage of freezing time in the contextual fear conditioning test was decreased at 1, 3 and 7 days after operation, the expression of CD11b at 1 and 3 days after surgery was up-regulated, the expression of miR-146a was down-regulated and IRAK1, TRAF6, NF-κB p65 expression was up-regulated at 6, 12 and 24 h after operation, TNF-α expression was up-regulated and IL-1β and IL-6 contents were increased at 12 and 24 h after operation in group At ( P<0.05). Conclusion:miR-146a is involved in the process of hippocampal inflammatory responses, and the mechanism may be related to the inhibition of IRAK1-TRAF6-NF-κB signaling pathway in mice.

OBJECTIVETo evaluate the efficacy of different modes of lymphadenectomies in the surgical treatment for early gastric cancer (EGC) in order to provide evidence for reasonable selection of lymphadenectomy for the ECG.

METHODSThe clinicopathological data of 325 EGC patients were reviewed. The lymph node metastasis (LNM) rate of different levels and the efficiency of different modes of lymphadenectomies were analyzed, and the correlation between LNM and clinicopathological features were analyzed either.

RESULTSThe overall LNM rate in the EGC was 14.8%, and the overall LNM degree was 3.0%. In the ECG located in the lower third of the stomach, the rate of first level nodal involvement was 14.5%, which was detected in the No. 3, No. 4, No. 5, No. 6 station of draining lymph nodes for the stomach; and it was 6.9% in the second level lymph nodes which were seen in the No.7 and No. 8a station. There was rare metastasis in the No. 1, No. 9, No. 11p, No. 12a and No. 14v station. In the ECG located in the middle third of the stomach, the rate of first level nodal involvement was 13.8% , which was found in the No. 1, No. 3, No. 5 and No. 6 station, and it was 6.9% in the second level nodes only seen in the No. 7 and No. 8a station. The LNM rate was significantly higher in the lesion larger than 3.0 cm in diameter, or having submucosa invasion, or being poorly differentiated, or with lymphatic involvement than that of the lesion smaller than 3.0 cm in diameter, without mucosa invasion or lymphatic involvement, or being well differentiated (P < 0.05).

CONCLUSIONBased on our data, it is suggested that the D1 or D1 + lymphadenectomy of the No. 7 station of lymph node may be suitable for the lesion smaller than 1.0 cm in diameter or only located in the mucosa; the D1 + lymphadenectomy of the No. 7 and No. 8a station of lymph nodes may be suitable for the lesion larger than 1.0 cm in diameter, or being depressed type or with submucosa invasion in the middle and/or lower third of the stomach. For the lesion larger than 3.0 cm in diameter, the No. 1 and No. 9 station lymph node should be dissected. It is also suggested that regular D2/ D3 lymphadenectomy should be avoided in the surgical treatment for the early gastric cancer whenever the tumor situation is suitable.

Objective To analyze the association of elevated carotid intima-media thickness(CIMT)with low-grade albuminuria in a community-based population. Methods A total of 10 375 participants aged 40 years or older were recruited using cluster sampling from Jiading district, Shanghai. Standardized questionnaires were adopted to collect information on health status and lifestyles. Anthropometric measurements including weight, height, and blood pressure, and biochemical tests for blood and urine were performed. CIMT was detected by B-mode ultrasound examinations. 9 523 subjects were included for final analysis. All these subjects were divided into 4 groups according to sex-specific urinary albumin to creatinine ratio ( UACR ) quartiles. CIMT≥upper decile of the population was defined as elevated CIMT and low-grade albuminuria was defined as UACR≥sex-specific upper quartile. The relationship between UACR and CIMT was investigated by multiple logistic regression analysis. Results The prevalence of elevated CIMT in this population aged 40 years or older with albuminuria in normal range was 21. 44%. Comparing to participants without elevated CIMT, those with elevated CIMT showed higher level of UACR (4. 79 vs 4. 51 mg/g, P<0. 01). The metabolic status was deteriorated with the increment of UACR level. The prevalences of elevated CIMT were 18. 99%, 19. 24%, 20. 20%, and 27. 33% from the lowest to highest UACR quartile, respectively(Ptrend<0. 01). After adjusting for some conventional cardiovascular risk factors, multiple logistic regression revealed that compared with the participants in the lowest quartile of UACR, those in the highest quartile had a 1. 25-fold risk of elevated CIMT. Conclusions This study shows that low-grade albuminuria is positively associated with elevated CIMT, independent of conventional cardiovascular risk factors in middle-aged and elderly adults.

OBJECTIVETo analyze the clinicopathologic features and prognosis of young patients with gastric cancer by comparing with older patients.

METHODThe clinicopathologic data of 157 younger adults (age, 40 years) was analyzed and compared retrospectively. All of the 1918 patients were surgically treated between January 1980 and December 2000.

RESULTSThe rates of poorly differentiation, diffusive growth, Borrmann 4 type, whole-stomach invasion were significantly higher in younger cases than those in the elder counterparts (P < 0.05), especially in young female patients. The rate of early gastric cancer was significantly higher in young patients than that in older patients (P < 0.05), especially in young male patients. There was significant difference between the survival rate of younger male cases (median survival, 35 months) and younger female cases (median survival, 19 months) (P = 0.0219), but no significant difference was found between elder male and elder female (median survival, 26 vs. 30 months). TNM stage, operative curability, gross type were independent predictive factors of survival for younger patients.

CONCLUSIONSYounger female gastric cancer patients tends to have worse prognosis than older patients, while younger male patients have better prognosis due to higher percentage of early gastric cancer when diagnosed. Pathologic staging and operative curability are the independent predictive factors of survival for younger patients.

OBJECTIVETo evaluate the detective efficacy of Chromogenic Coliform and Escherichia Coli Agar (CCEA).

METHODSA new chromogenic medium CCEA prepared by Huankai laboratory was used to compare with a classical medium of violet red bile agar (VRBA), and other two Chromogenic media Agar I and Agar II by detecting separately 11 reference strains, thirteen sterile samples with Coliform or E.coli and other four samples, and the accordant rates of detection were observed.

RESULTSCCEA had the good selectivity. To seven kinds of quality strains in the resultant analysis, CCEA with VRBA and Agar I had not shown salience difference (P > 0.05), and CCEA with Agar II had significant difference (P < 0.05). CCEA showed more advantages than the Agar II. To thirteen sterile samples with Coliform or E.coli in resultant analysis, CCEA with Agar I and Agar II had shown no significant difference (P > 0.05), while CCEA with VRBA had significant difference (P < 0.05). CCEA might be more advantageous than the VRBA. In analysis of the four actual samples of Coliform, CCEA with VRBA, Agar I and Agar II showed no significant difference (P > 0.05). The accordant rates were 90%, 71.88%, 86.25% and 81.25% respectively, showing CCEA > Agar I > Agar II > VRBA. To two actual samples of E.coli in the resultant analysis, the CCEA with Agar I and Agar II had not shown significant difference (P > 0.05). The accordant rates were 100% respectively.

CONCLUSIONSThe CCEA might be more advantageous than the VRBA, having the same efficacy as with Agar I and Agar II.
