Objective To investigate the typing, staging and therapeutic outcome of intrahepatic cholan-giocarcinoma (ICC). Methods The clinical data of 60 ICC patients who were admitted to the Renji Hospital of Shanghai Jiaotong University from January 2000 to December 2008 were retrospectively analyzed. ICC was classi-fied according to the type and TNM staging proposed by the Liver Cancer Study Group of Japan (LCSGJ). The relationships between typing, staging, surgical procedures and therapeutic outcome were investigated, as well as the relationship between the LCSGJ staging system and UICC staging system. Results The 1-, 3-, and 5-year survivals of the 60 ICC patients were 44% (23/52), 19% (10/52) and 10% (5/52), respectively. The median survival time for patients with radical resection (n =30) , liver transplantation (n = 10), palliative surgery (n = 11) and exploratory laparotomy (n=9) were 13, 3, 3 and 1 months, respectively. The radical resection rates for mass-forming type, periductal-infiltrating type, intraductal growth type and mixed type were 23/31, 9/15, 5/6 and 3/8, respectively. There were significant relationships between tumor type, degree of differentiation and prog-nosis (χ2 = 8. 308, 10. 009, P < 0. 05), and between tumor type and lymph node metastasis (χ2 = 13. 261, 5.702, P <0.05). There was no significant difference in survival time between patients with different pathological types, but the prognosis of patients with mucinous adenocarcinoma was better than that in the other types, with a median survival time of 20months. The median survival time of patients in LCSGJ stage Ⅳ was 3. 0 months, which was significantly longer than that in UICC stage Ⅳ (χ2 =3. 877, P <0. 05). Tumor staging was intimately related to the macroscopic type χ2 =8.288, P <0. 05). Conclusions The prognosis of ICC is poor. The typing and staging of LCSGJ is concise and practical, which is helpful in guiding treatment and evaluating progno-sis. Surgical treatment should be applied to mucinous ICC, and liver transplantation is not recommended for the treatment of ICC.

Objective The properties of anthocyanins in Suaeda heteroptera Kitag.were investigated.Methods Properties of the extract were determined via spectral absorption,physco-chemical analyses.Results Spectrogram results showed that the red pigment was classified to anthocyanins.The color properties of the pigment were similar to plant anthocyanins and pH changes could affect the tone of the color.The pigment was soluble in water,alcohol;slightly soluble in acetone;and insoluble in petroleum ether.Under natural light,degradation of the pigment could be accelerated.High temperature was disadvantage to the pigment stability.Redox stability was very low.Fe~(2+),Mg~(2+),Cu~(2+) and Mn~(2+) did not significant affect the tone of the color.Conclusion The pigment from Suaeda heteroptera Kitag.is water-soluble anthocyanins,and may be important nature edible pigment resource.

Objective To explore the difference of gene profile between Cold syndrome and Heat syndrome in traditional Chinese medicine in stable and active stage of rheumatoid arthritis (RA). Methods Peripheral CD4+ lymphocytes from RA cases with defined Cold or Heat syndrome in TCM and healthy persons were obtained. Genechip analytical techniques were applied for analysis. Results There are 63 genes found different between active stage and stable stage of RA patients, and they refer to immune responses and signal transduction mainly. 48 genes were found different between Cold syndrome and Heat syndrome in stable stage of RA patients, and only 4 gene was found in the 63 genes for stable and active stage comparison, they are mainly referring to functional metabolism. 59 genes were found to be different among Cold syndrome and Heat syndrome in active stage of RA patients, and among them, no gene was same as in the 48 genes for Cold and Heat syndrome comparison in stable stage of RA, nor in the 63 genes for stable and active stage comparison. Conclusion The genes referred with Cold or Heat syndrome in the stable and active stage of RA are different with those genes referring to the difference of gene profile between active stage and active stage of RA, and further suggest that differentiation theory in traditional Chinese medicine have solid foundation in gene expression profile.

Objective To investigate the effects of Xuebijing injection on expression of myeloid cell triggering receptor-1(TREM-1)and the plasma levels of soluble TREM-1(sTREM-1),tumor necrosis factor-α(TNF-α), interleukin-6(IL-6)in patients with severe sepsis. Methods Twenty patients with severe sepsis admitted into Critical Care Medicine Department,Affiliated Hospital of Nantong University were given comprehensive treatments according to the guidelines for management of severe sepsis and septic shock(2004),and they were divided into Xuebijing group and control group(each 20 cases). The Xuebijing injection group was given Xuebijing injection 50 mL,3 times daily for 5-7 days followed by regular treatments. The changes in blood TREM-1 mRNA expression and plasma concentrations of sTREM-1,TNF-α,and IL-6 were detected before and after treatments on the 3rd and 5th day,and the above indexes were compared between the two groups. Results Before treatments,there were no significant differences in TREM-1 mRNA expression and levels of sTREM-1,TNF-α,IL-6 between two groups (all P>0.05). The TREM-1 expression and plasma concentrations of sTREM-1,TNF-α,and IL-6 of two groups were declined after treatments compared to their baselines,the degree of decline being more prominent in Xuebijing group〔TREM-1 mRNA 3 days:1.065±0.277 vs. 1.217±0.301,t=-3.267,P=0.047;5 days:0.912±0.239 vs. 1.071±0.254,t=-5.072,P=0.032;sTREM-1(ng/L):146.93±13.76 vs. 176.22±19.46,t=-5.442,P=0.033;TNF-α(ng/L):77.51±11.28 vs. 107.72±13.17,t=-4.355,P=0.032;IL-6(ng/L):288.35±14.59 vs. 323.89± 24.51, t=-3.941,P=0.028〕. Conclusion Early implication of Xuebijing injection is of great significance in patients with severe sepsis,it may reduce the expression level of TREM-1 and serum levels of downstream inflammatory mediators,that is beneficial to the control of inflammatory responses and improvement of systemic inflammatory response syndrome in such patients.

Objective To investigate the positive rates and susceptibility of Ureaplasma urealyticum(Uu) and Mycoplasma hominis(Mh) in urogenital mycoplasma infection under three years.Methods Culture,identification and susceptibility test were performed on 4 414 specimens collected from suspected patients with mycoplasma infection by using Antu mycoplasma kits.Results In the 4 414 patients,2 295 cases with mycoplasma infection were detected and the positive rate was 51.99％.The infection rates of Uu and Mh respectively were 40.69％ and 2.08％,and the both infection rate was 9.22％.Antibiotic sensitive rates of josamycin(JOX),doxycycline(DOX),clarithromycin(CLA),gatifloxacin(GAT) and erythromycin(ERY) were 96.03％,95.51 ％,78.69 ％％,77.21 ％ and 72.55 ％.Drug resistant rates of roxithromycin(RXT),thiamphenicol (THI),clindamycin (CLI) and clarithromycin(CLA) were 16.90％,22.27％,41.96％ and 17.60％.Conclusion Uu is the predominant mycoplasma in urogenital tract infection in the study.DOX,JOS,GAT and ERY can be chosen as the fist line drugs for the treatment of urogenital tract infection.RXT,THI,CLI and CLA with high drug resistant rates are not recommended to be used.

Objective To investigate the significances of karyotyping analysis on umbilical cord vein blood lymphocytes in the diagnosis of abnormal karyotypes in middle to late period of pregnant fetus.Methods A volume (0.5 ～ 1 ml) of umbilical cord vein blood was extracted from pregnant women in third trimester pregnancy with prenatal detection indications,and collected in sterilized anticoagulant tube.Lymphocytes were cultured and collected for karyotyping analysis after fixed and dropped on slides.Data were analyzed statistically.Results Lymphocytes were cultured successfully in 1 211 cases out of total 1 213 cases collected.Totally 142 abnormal karyotypes were found,which includes 81 cases (detection rate 6.68 ％) of non-heteromorphic abnormal chromosomes and 61 cases (detection rate 5.03％) of heteromorphic chromosomes.Among these abnormal karyotypes,50 cases (accounting for 35.21％ in total abnormal cases) of aneuploidy include 4 cases of chimerical karyotype.Structural abnormalities were found in 31 cases (accounting for 21.83％ in total abnormal cases) samples including 11 cases of translocations,17 cases of inversion and 3 cases of deletion.Conclusions Based on our findings,karyotyping analysis on umbilical cord vein blood lymphocytes could be an effective method for detect abnormal karyotypes in middle to late period of pregnant fetus and played an important role in prenatal diagnosis.

Objective To explore the effects of the stromal cell-derived factor on chemotaxis of cord blood ACl33+ cells.Methods The optimal SDF-1 concentration is detected in Transwell system.Migration was calculated from the number of cells found to have passed through an 8-um pore size polycarbonate membrane.Results The chemotactic rate of fresh cord blood AC133+ cells increases along with the concentration of SDF-1,however,it tends to be stable when the concentration of SDF-1 reaches 150 ng/ml.There is no difference in the chemotactic rate of cord blood AC133+ cells between the group with CXCR4-blocking antibody and the group without SDF-1.Conclusion Transwell Plate can simulate the phenomenon of cell crossing endothelium.The chemotactic rate of cord blood AC133+ cells increases progressively along with the concentration of SDF-1,however,the chemotactic rate tends to equability when SDF-1 reaches a certain concentration.The chemotactic rate does not have a marked change while continuing to increase the concentration of SDF-1.There is no difference in the chemotactic rate of cord blood AC133+ cells between the group using CXCR4-blocking antibody and the group without SDF-1.

Objective To explore the value of procalcitonin (PCT) in the prediction of the prognosis and severity of bacterial infection in critically ill patients.Methods A total of 116 eligible patients with bacterial infection admitted in the intensive care unit were enrolled in this prospective study from February,2012 through November,2012.Within 24 hours after admission,the serum PCT was determined with immune-chromatography and acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score of patients was calculated.Based on the 28-day clinical outcome of patients,the patients were divided into fatal group (n =36) and survival group (n =80).The differences in PCT and APACHE Ⅱ score between the two groups were compared with t test or rank-sum test.The correlation between PCT and APACHE Ⅱ score was determined with Spearman's correlation analysis.Both PCT and APACHE Ⅱ score were analyzed separately and jointly with area under receiver operator characteristic curve (ROC curve,AUC) to predict 28-day survival.Comparison of prediction performance for predicting 28-day survival of patients with bacterial infection between PCT and APACHE Ⅱ was made with U test.Results PCT concentration was significantly higher in fatal group than that in survival group [5.36 (2.07,25) vs.0.24 (1.00,2.14)] (Z =5.596,P ＜0.01).APACHE Ⅱ score within 24 hour after admission was significantly higher in fatal group than that in survival group (24.30 ± 6.71) vs.(16.03 ± 7.23),t =6.147,P ＜ 0.01.Positive correlation between PCT and APACHE Ⅱscore was found to be statistical significance (r =0.388,P＜ 0.01).When rates of 28-day survival in patients were predicted by using PCT and APACHE Ⅱ score,the areas of under curve were 0.804 and 0.792,respectively.AUC of PCT was tenuously larger than that of APACHE Ⅱ score (U =0.2073,P =0.802).Using PCT and APACHE Ⅱ score together to predict 28-day survival,AUC (0.817) was increased.The joint prediction performance was higher than that of either alone,increasing the sensitivity to 90.7％ and the specificity to 75.2％.Conclusions Serum PCT can reflect the severity of the illness and prognosis of infectious disease in the intensive care unit.It can serve as a sensitive marker of predicting 28-day survival.Combining PCT and APACHE Ⅱ score together can increase the prognostic value.

With the continuous use of immunosuppressive agents routinely, the long-term survival rate of organ transplant recipients has been incessantly improved. However, the risk of de novo malignancies is also increasing, which has become the second cause of death after organ transplantation. De novo gastrointestinal malignancies are common after liver or kidney transplantation, mostly with advanced stage when diagnosed and poor prognosis. There is a significant trend in the development of de novo malignancies in transplant recipients, which is probably related to factors, including direct or indirect effects of immunosuppressive agents, precancerosis and survival time of transplanted grafts and recipients. Long-term postoperative use of immunosuppressive agents can keep the recipient's immune system in the inhibitory state, which provides the conditions for tumor cells to escape immune surveillance and to proliferate. In addition, some immunosuppressive agents [such as calcium phosphatase inhibitor (CNI)] are carcinogenic and the use of anti-tumor combined with immunosuppressive drugs can be considered [such as mycophenolate mofetil (MMF), mammalian rapamycin target protein (mTOR) inhibitors]. De novo gastrointestinal malignancy has no specific clinical manifestations. It is suggested that the recipients need to strictly comply with the follow-up time, avoid exposure to carcinogens, treat the precancerosis positively and have a medical examination carefully. At present, there are no literatures and guidelines about a standard treatment for de novo gastrointestinal malignancies after transplantation. The primary treatment of de novo malignancies should be adjusting the dosage of immunosuppressive agents to ensure that their minimum dose can effectively maintain the graft function. For patients with stable postoperative organ function and without acute or chronic rejection, the dosage of immunosuppressive agents can be reduced gradually to avoid an excessive immunosuppressive effect. Thereafter, the incidence of de novo malignancies is reduced to a minimum. Minimization of using CNI as soon as possible after transplantation has been widely recognized, and CNI plus mTOR inhibitor or MMF has become a relatively reasonable method.
