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 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.

10.Occurrence, diagnosis and treatment of de novo gastrointestinal malignancies after organ transplantation.
Chinese Journal of Gastrointestinal Surgery 2017;20(10):1206-1210
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.
