Acute and chronic graft rejection are the major factors leading to graft non-function.There is an active expression of chemokines early after transplantation.They recruit T cells and antigen presenting cells selectively to the graft, leading to inflammatory reaction and finally to graft non-function.Accordingly,monitoring the expression status of chemokines and their receptors regularly may help to the diagnose rejection.To determine one or more chemokines or their receptors as the new targets for anti-rejection therapy will be of great clinical significance.This review focuses on the research progression in the above areas.

Objective To study the preventive effects of vitamin K2 on tumor recurrence in patients with hepatocellalar carcinoma (HCC) after radical resection. Methods The clinical data of 50 patients with HCC who received radical resection from March 2006 to March 2007 in No. 181 Hospital of PLA were analyzed retrospec-tively. All the patients were divided into 2 groups according to the random number table. Twenty-six patients in vitamin K2 group were administered with menatetrenone (45 mg per day), and the rest 24 pateints were in the control group. The accumulative and tumor-free survival rates, differences between the 2 groups, multivariate factors for prognosis were analyzed by Kaplan-Meier curve, Log-rank test and Cox regression model, respectively. Results During a period of 36 month follow-up, 10 patients died and 28 had tunor recurrence. The 1-, 2-, 3-year accumulative survival rates were 96%, 92% and 83% in vitamin K2 group, and 96%, 82% and 63% in control group (χ2 = 3.61, P > 0.05). The 1-, 2-, 3-year tumor-free survival rates were 92%, 60% and 38% in vitamin K2 group, and 75%, 42% and 12% in control group, with significant difference between the 2 groups (χ2 =5.61, P <0.05). Univariate and multivariate Cox proportional hazard analysis showed that without taking menate-trenone, the preoperative level of alpha fetoprotein (AFP) ≥800 μg/L and vascular invasion were the indepen-dent risk factors for tumor recurrence. Conclusions Vitamin K2 has a suppressive effect on tumor recurrence of HCC, while patients with AFP≥800 μg/L before operation or with vascular invasion have poor prognosis.

Isolated alkaloids from Coptis chinensis Franch. The compounds were identified as berberine, columbamine, groenlandicine, jatrorrhizine, magnoflorine, corydaldine and ferulic acid methylester. Then measured their bitter degree based on the electronic tongue and evaluated the antibacterial. The results based on the Electronic Tongue showed that berberine, columbamine, groenlandicine and jatrorrhizine have higher bitter degree than magnoflorine and corydaldine. And they also appeared better antibacterial activity on E. coli and S. aureus. The correlation coefficients between bitter degree and the two bacteria antibacterial activity were 0.983 and 0.911. So there was close relationship between the bitter degree and antibacterial activity of bitter components. Thus, it is confirmed further that bitter components are the material foundation of medicinal effectiveness of bitter herbs.

AlM:To study the treatment effect of traditional Chinese medicine in the treatment of high myopia macular hemorrhage, using Chinese medicine etiology and pathogenesis, syndrome differentiation treatment, and provide the basis for the clinical treatment. METHODS: Eighty patients ( 135 eyes ) with high myopia macular hemorrhage were selected in the hospital from January 2012 to september 2014 as treatment group, and applied traditional Chinese medicine treatment. Forty-five patients (64 eyes) with the same period, as the control group, received routine western medicine treatment. After 1mo treatement, the treatment effect and vision improvement situation of two groups were observed, and after 6mo follow-up, the relapse was observed.RESULTS: The total effective rate of treatment group was 85. 19% (115/135), higher than the control group 78. 13% (50/64) (P<0. 05). The average corrected visual acuity of treatment group was 0. 48±0. 11, higher than the control group 0. 36 ± 0. 09, the difference was statistically significant (P<0. 05). The average diopter and macular bleeding scope of the treatment group were -9. 81±0. 85D and 0. 51 ± 0. 27PD, lower than the control group -10. 76 ± 0. 91D and 0. 78 ± 0. 23PD, the differences were statistically significant ( P < 0. 05 ). The eye ground hemorrhage absorption time of treatment group was 25. 34±2. 28d, less than the control group 29. 72 ± 2. 13d, the difference was statistically significant (P<0. 05). The bleeding again of the control group 7. 81% ( 5/64 ), higher than the treatment group was 5. 19% (7/135), the difference was statistically significant (P<0. 05).CONCLUSlON: Evidence-based treatment of traditional Chinese medicine for high myopia macular hemorrhage has good clinical effect, can shorten the treatment time, and is beneficial to the recovery of postoperative vision, worthy of clinical popularization and application.

Objective To-identify the factors associated with radiation-induced liver disease (RILD) and to describe the probability of RILD using the Lyman normal tissue complication(NTCP) model for primary liver carcinoma(PLC) treated with hypofractionated conformal therapy (CRT).Methods A total of 109 PLC patients treated with hypofractionated CRT were prospectively followed according to the Child-Pugh classification for liver cirrhosis,93 patients in class A and 16 in class B.The mean dose of radi- ation to the isocenter was (53.5?5.5) Gy,fractions of (4.8?0.5) Gy,with interfraction interval of 48 hours and irradiation 3 times per week.Maximal likelihood analysis yielded the best estimates of parameters of the Lyman NTCP model for all patients;Child-Pugh A and Child-Pugh B patients,respectively.Results Of all the patients,17 developed RILD (17/109),8 in Child-Pugh A(8/93 ) and 9 in Child-Pugh B(9/ 16).By multivariate analysis,only the Child-Pugh Grade of liver cirrhosis was the independent factor (P= 0.000) associated with the developing of RILD.The best estimates of the NTCP parameters for all 109 pa- tients were n=1.1,m=0.35 and TD_(50) (1)=38.5 Gy.The n,m,TD_(50) (1) estimated from patients with Child-Pugh A was 1.1,0.28,40.5 Gy,respectively,compared with 0.7,0.43,23 Gy respectively,for patients with Child-Pugh B.Conclusions Primary liver cancer patients who possess Child-Pugh B cirrho- sis would present a significantly greater susceptibility to RILD after hypofractionated CRT than patients with Child-Pugh A cirrhosis.The predominant risk factor for developing RILD is the severity of hepatic cirrhosis in the liver of PLC patients.
