Objective To compare the result of percutaneous or open drainage for muhilocular bacterial liver abscess. Methods The clinical data of 45 patients with multilocular bacterial liver abscess were reviewed retrospectively over the past 5 years. Twenty-one cases underwent B-us or CT-guided pereutaneons drainage (PD) and 24 received surgical drainage (SD) as the first-line treatment. The treatment outcomes in both groups were compared, and clinical end-points included time to defervescence, failure of treatment, secondary procedures, hospital stay, morbidity, and mortality. Results The time of defervesecnce was not statistically different between the two groups (4.85 day vs. 4.38 days, P＞0.05). However, patients in SD group suffered from less treatment failures (2 cases vs. 9 cases, P<0.05), less requirement for secondary procedures (1 cases vs. 11 cases,P<0.01), and shorter hospital stay (8 day vs. 11 days, P<0.05). There was no difference in morbidity or mortality rates between the two groups. Conclusions It was concluded that for multilocular liver abscess, SD provides better clinical outcomes than PD in terms of treatment success, number of secondary procedures, and hospital stay with comparable morbidity and mortality rates. SD should be considered as first-line treatment for multilocular bacterial liver abscesses.

Objective To investigate the immunosuppressive regimen of cyclosporine A(CsA) reduced or withdrawn in the HBV-DNA positive kidney transplanted patients. Methods The program of 64 kidney transplanted patients with HBV-DNA positive from Jan,2004 to Dec,2007 were analyzed, the patients were divided into 3 groups ①CsA + MMF group(A group) ;②FK506 + MMF group(B group) ;③low dose of CsA + SRL group(C group). All the patients received entecavir to resist HBV replication and were followed up for acute rejection incidence,liverfunc- tion and HBV-DNA test for 6 months. Results There was no significant difference in 3 groups about acute rejection incidence rate. Liver dysfunction took place in 12 patients of A group (80%) ,8 patients(53%) in A group HBV-DNA became negative; 5 patients (20%) in B group appeared the liver dysfunction, HBV-DNA became negative in 18 patients(75%). 4 patients in C group(16%) appeared liver dysfunction sHBV-DNA was negative in 18 patients (72%) of C group. Conclusion It was safe and efficient for the immunosuppressive regimen of cyclosporin A re-duced or withdrawn in the HBV-DNA positive kidney transplanted patients,not increasing the incidence of acute re-jection and aggratating the liver injury.

Objective To explore the related protein which lead to rheumatoid arthritis (RA) and to find different proteins associated with active RA by comparing the expression levels of proteins in the peripheral blood mononuclear cells (PBMCs) of healthy individuals to patients with rheumatoid arthritis using a proteomics approach. Methods Samples of peripheral blood were collected from 9 patients diagnosed as active RA and 9 healthy individuals. PBMCs were isolated from blood using lymphoeytes separation medium. The total protein was extracted from the peripheral blood mononuclear cells. The total protein from either RA patients or normal controls was prepared by means of immobilized pH gradient based on two-dimensional gel eleetrophoresis. After Coomassie brilliant blue G250 staining, gel-image analysis was performed by using PDQuest.The differentially expressed proteins were identified by matrix-assisted laser desorption ionization-time-of-flight mass spectrometry (MALD I-TOF-MS). Then APOA-I was validated by RT-PCR. Results 2-DE patterns of PBMCs from controls and RA patients were presented. The results showed that the average number of protein spots was 556 and 579 respectively, and the corresponding average matching rate was 89.4％ and 88.5％ respectively. Gel-image analysis revealed that there were 23 differential protein spots. Fourteen of total 18 differential protein spots were successfully identified by MALD I-TOF-MS, of which 8 proteins were upregulated such as actin beta, fibrinogen beta chain, ApoA-I ; and 6 proteins such as peroxiredoxin-2, glu-tathione S-transferase omega 1 were down-regulated when compared with controls. The result of ApoA-I by RT-PCR was consistent with the proteomics results. Conclusion Some differentially expressed proteins are observed in the PBMCs of patients with rheumatoid arthritis, which may play a potential role in the pathogenesis of RA.

[Objective] To establish an effective and stable method to induce hematopoietic cells from embryonic stem(ES) cells,the phenotype and function of ES-derived hematopoietic cells induced by stromal cell conditioned medium (SCCM) of yolk sac (YS),fetal liver (FL) or bone marrow (BM) were analyzed and compared.[Methods] 10% of YS-SCCM,FL-SCCM or BM-SCCM was added to culture system for differentiation of ES cells.Flow cytometric analysis was used to identify expression of Flk1,Integrin α4,Sca-1,and CD34.Colony analysis was used to identify the quantity of high proliferative potential colony-forming cells (HPP-CFC) in differentiated ES cells.The yield of CFU-S (colony-forming unit-spleen) was also analyzed by transplanting ES cell derivatives into lethally irradiated mice.[Results] Expression of Flk1,Integrin α4,Sca-1,and CD34 could be tested on induced EB cells.The percentage of Flk-1+,Integrin α4+ and Sca-1+ cells induced by were 3.03%,2.9%,and 13.74%,respectively,which are greater than other groups.The percentage of CD34+ cells induced by BMSC-CM was 1.07% which was greater than other groups.The yields of HPP-CFC from hematopoietic cells induced by FLSC-CM or BMSC-CM were 7.4 /105 cells (P ＜ 0.01) and 5.8 /105 cells (P ＜ 0.05) which were greater than the yields of control group.The yields of CFU-S from hematopoietic cells induced by FLSC-CM or BMSC-CM were 8.5/5 × 105 cells and 6.75/5 × 105 cells which were also greater than the yields of control group (P ＜ 0.001).[Conclusion] Both YS-SCCM,FL-SCCM,and BM-SCCM could promote hematopoietic differentiation of ESE14.1 cells.Hematopoietic differentiation induced by FL-SCCM or BM-SCCM is more effective,which generates hematopoietic progenitor cells with normal function.Application of FL-SCCM generates more primitive hematopoietic progenitor cells than that of BM-SCCM.

OBJECTIVETo evaluate the influence of superovulation by GnRHa protocol and pregnant mare's serum gonadotropin (PMSG) alone on the expression of estrogen receptor (ER), progesterone receptor (PR) and leukemia inhibitory factor (LIF) mRNA on endometrium.

METHODSForty-five female ICR mice were randomly allocated into 3 groups:(1) GnRHa+PMSG group: alarelin was give first for desensitizing the pituitary, then superovulation with PMSG; (2) PMSG group: mice were injected with PMSG only; (3) Natural cycle group: mice were given with same volume of saline. Endometrium samples were taken at 48 hours after given hCG or ovulation (control group). ER and PR in glandular cells were detected with SP immunohistochemistry semiquantitatively. Expression of LIF mRNA on endometrium was detected with reverse transcriptase-polymerase chain reaction (RT-PCR) analysis.

RESULTThe positive rate(%) and expression intense (AU) of ER and PR on glandular epithelium cells were significantly lower in GnRHa+PMSG group and PMSG group than those in natural cycle group (all P <0.01). The expression of LIF mRNA was significantly lower in GnRHa+PMSG group and PMSG group than that in natural cycle group (all P <0.01); but the expressions of ER, PR and LIF in GnRHa+PMSG group were higher than those in PMSG group.

CONCLUSIONThe protocol with GnRHa down regulates the expressions of ER, PR and the LIF mRNA on the mice of secretive phase endometrium, suggesting it may have an adverse effect on the endometrial receptivity in mice, but it may still be better than PMSG alone.

Objective To evaluate the development level of public health in Zhejiang Province during China's 12th Five-Year Plan period (from 2011 to 2015)for health policy making in the future. Methods Totally 30 indexes were first summarized into 4 components, including the residents' health level, the allocation of public health resource, the level of public health service and public health security. The evaluation index system was developed by Delphi method. The indicators of 2010 were selected as the baseline for comparison with those corresponding indicators from 2011 to 2015. Each index(the comprehensive development index, the developmental speed, as well as the indicator index)calculated during 12th Five-Year Plan period was evaluated after the targeted indicators were weighed. Results Overall, at a provincial level of Zhejiang, the comprehensive development index was increased from 100 in 2010 to 138.44 in 2015, representing an annual average development speed of 6.72%. The annual average development speed of 13 indexes, ranging from 6.72% to 26.18%, were higher than those in the China's 11th Five-Year Plan period(6.72%); while the annual average development speed of another 17 indexes was lower, with 1 index below zero. However, the number of medical staff per 10000 population(5.23), the treatment success rate among new smear-positive cases (90.76%)and the number of annual outpatient visits in primary hospitals(49.45%)in Zhejiang Province were lower than those in China during the same period(6.39, 92.49%, 56.40%). At a prefectural level, the comprehensive development index fluctuated from 128.65 in Quzhou to 156.35 in Jiaxing and the developmental speed was from 3.90% to 11.26%. These results indicated that the coefficient variant(CV)was 5.76 during China's 12 th Five-year Plan period, which had recorded the historically lowest level since 2010. Conclusion During the China's 12th Five-year Plan period, the development of public health in Zhejiang Province was steadily enhanced. Public health variably developed across 11 prefectures with shrinking gaps. Nevertheless, the number of medical staff per 10 000 population, the treatment success rate among new smear-positive cases and the number of annual outpatient visits in primary hospitals should be improved.

Objective To make clear the incidence, clinical characteristics and possible regional difference of gallbladder cancer in China.Methods A total of 430 cases of gallbladder cancer from 28 hospitals between 1986-1996 were reviewed, according to a standard protocol called "the clinical epidemiological list of gallbladder cancer".Results The incidence of gallbladder cancer was higher in the females than in the males. There was significant difference in the incidence between the north and south of China, and between the mountain area and flatlands. Gallbladder cancer accounted for 1.6% of bile tract disease in the same period. Gallstones were found in about 50% of the cases of gallbladder cancer. The clinical symptoms included abdominal pain, ictus, etc. The major pathohistologic type was adenocarcinoma, and 58% of tumors were localized in the whole gallbladder. Metastasis occurred mainly along the biliary tract or directly to the bed of gallbladder and liver. Ultrasonography and CT were useful to diagnosis. The positive imaging diagnostic rate was higher in the first 5 years (1986-1990) than in the last 5 years (1991-1996, P<0.05). The rate of operative resection was 100% for stage Ⅰ and Ⅱ disease, 75% for stage Ⅲ and Ⅳ, and significantly lower for stage Ⅴ (P<0.05). The 3-year survival rate in patients with stage Ⅰ or Ⅱ disease was significantly higher than that in those with terminal cancer (P<0.05). Conclusions There is specific populational, time and regional difference in the distribution of gallbladder cancer. Ultrasonography and CT are the most important diagnostic methods. Early diagnosis and early radical resection are the key to increasing the 5-year survival rate.
