Liver transplantation is one of the most effective treatment of hepatocellular carcinoma.And rapamycin is a new class of immunosuppressors already in use after liver transplantation.Recently.more and more studies find that rapamyein not only can exert immunosuppressive effects but also has antitumor properties.Therefore,the research about rapamycin in hepatocellular carcinoma has become a focus.Herein,we review the progress of rapamycin in the treatment of hepatocelhlar carcinoma together with current results and future developments.

Objective:To investigate the effects of iron sucrose combined with recombinant human erythropoietin(EPO)on perioperative anemia and early functional recovery in elderly patients with intertrochanteric fractures.Methods:A retrospective comparative analysis was performed on 78 elderly patients who received PFNA treatment for intertrochanteric fractures in our hospital from July 2016 to December 2018.In the observation group, 40 cases were treated with iron sucrose combined with erythropoietin during the perioperative period.No perioperative intervention measures were taken for the control group.Hemoglobin(Hb)levels at 1, 3, 5, 7 days and before discharge and Harris scores of hip joints before surgery, 2 weeks and 3 months after surgery were compared between the two groups.Results:Hb levels were higher in the observation group than in the control group at 5 d[(98.8±8.6 g/L vs.92.2±8.5 g/L, t=3.389, P=0.001)]and 7 d[(105.4±8.9)g/L vs.(94.8±8.5)g/L, t=5.370, P=0.000]after surgery and before discharge[(115.4±8.6)g/L vs.(100.6±8.2)g/L, t=7.771, P=0.000]. Harris scores were higher in the observation group than in the control group 3 months after surgery(82.4±3.8 vs.75.8±2.5, t=8.933, P=0.000). Pearson' s correlation analysis showed that Hb levels at 5d and 7d after surgery were positively correlated with Harris scores at 3 months after surgery.Hb levels before discharge had an effect on Harris scores at 3 months after surgery. Conclusions:The combined administration of iron sucrose and EPO perioperatively can promote postoperative Hb recovery, reduce the incidence of anemia, accelerate early functional recovery and improve the quality of life in elderly patients with intertrochanteric fractures.

Objective To explore the level of Th2 type cytokines including IL-4, IL-10 and IL-13, and the immunoreg-ulation of cytokines in patients with neurocysticercosis. Methods Lymphocytes in patients with neurocysticercosis were separated from the blood sample with density gradient centrifugation and the total RNA was extracted by guanidine isothiocynate method. cDNA was synthesized by reversed transcription reaction. The target gene was then amplified by PCR. The PCR products were analyzed by electrophoresis. Results Results of RT-PCR showed that cytokines mRNA in lymphocytes of peripheral blcod were detected in 27 patients with neurocysticercosis but not in the other 3 cases. Among the positive cases, mRNA of IL-4, IL-10 and IL-13 was detected in 16, 17 and 14 cases respectively and mRNA of IL-4, IL-10 and/or IL-13 was detected in all the 27 cases. In the detection of lymphocytes in peripheral blcod of 10 healthy subjects, expression of IL-4 and IL-10 was found in only one case at low level. Conclusion The study revealed that Th2 associated cytokines were expressed at high level and the humoral immunocompetence was relatively strong in patients with neurocysticercosis.

Objective To examine the application value of reticulocyte hemoglobin content (CHr)for diagnosing iron deficiency in premenopausal women.Methods The levels of CHr,hemoglobin (Hb), mean cellular volume(MCV),red cell distribution width (RDW) were measured on the ADVIA 120 (Bayer Diagnostics) automated hematology analyzer.Transferrin saturation (TS) and ferritin (SF) were measured on chemistry analyzer.Results CHr in iron deficiency without anemia group were significantly lower than that in the healthy control group (P＜0.01)and significantly higher than that in iron deficiency anemia group(P＜0.01).CHr in anemia of chronic disease group were significantly higher than that in iron deficiency anemia group(P＜0.01).Receiver operator characteristic curve (ROC) analysis in diagnosis of iron dificiency without anemia demonstrated that the area under the curve for CHr,SF,RDW,MCV,Hb were 0.872,0.798,0.721,0.713,0.677,respectively (P＜0.01).So CHr has a better overall sensitivity than SF,Hb,MCV and RDW in the diagnosis of iron deficiency without anemia.ROC also showed that the area under the curve for Hb,RDW,CHr,SF and MCV was 1.000,0.969,0.958,0.953 and 0.926,respectively (P＜0.01) in iron deficiency anemia.Conclusion CHr is the early and sensitive predictor of iron deficiency in premenopausal women,especially for the diagnosis of iron deficiency without anemia.

This paper describes the anti-inflammatory, antipyretic and analgesic effects of Sudoxicam ( Sud) synthesized by Shenyang Pharmaceutic College.Sud is found to possess significant anti-inflammatory, antipyretic and analgesic quality in such animal models as carrayeenan-induced paw oedema ( ED50=5.26mg/kg ) , tylolinduced ear oedema in mice, adjuvant-induced arthritis in rats, yeast-induced fever in rats, acetic acid-induced arithing ( ED50= 5.0mg/kg ) and hot plate-induced pain reaction in mice.

Objective To investigate the biological activity of cytokine-induced killer(CIK)cells in vitro.Methods Lymphocytes isolated from peripheral blood in leukemic children were induced with interferon-?(IFN-?),anti-CD3 monoclonal antibody(CD3McAb)and interleukin-2(IL-2)and co-cultured with dendritic cells(DC)to generate DC-CIK cells.The morphology and immunophenotype of these cells were determined by electron microscopy and flow cytometry,respectively.Cytotoxicity of DC-CIK cells against leukemia cell lines was measured by the methyl thiazolyl tetrazolium (MTT) assay.Interleukin-12(IL-12),tumor necrosis factor-?(TNF-?)levels released by DC-CIK cells were quantified by enzyme-linked immunosorbent assays.Results Induced DC-CIK cells were regular,round and transparent with variable cell volume and cellular aggregation.At the 0th-4th day,its amplification was very slow,and it increased quickly at the 5th-8th day,it reached its peak amplification at the 9th-10th day,at approximately 100-fold.The main effector cells in this population were CD3+CD8+ cells and CD3+CD56+ cells.DC-CIK cells were cytotoxic to B95 cells,K562 cells and HL-60 cells,with the highest cytotoxicity towards B95 cells.The expression levels of IL-12 and TNF-? in supernatant were very high.Conclusions DC-CIK cells induced with cytokines displayed powerful amplification and strongly killing activities in vitro.It suggested that DC-CIK cells induced with cytokines may play killing activities through Th1 pathway in vitro,as a result of high secretion of Th1 cytokines,such as IL-12 and TNF-?.

BACKGROUND:The micro-ecological environment has been broken when the ocular prosthesis was inset into the conjunctival sac. The recede of self cleaning function is more conducive to the microbial growth and colonization. The cleaning of plaque biofilm on ocular prosthesis surface affects the patient's wearing comfort and quality of life. It is necessary to seek an effective cleaning method. OBJECTIVE:To compare the clearance effect of five cleaning methods on the palque biofilm on ocular prosthesis surface. METHODS: The conjunctival secretions from 84 patients who were subjected to ocular prosthesis repair were taken for bacterial culture and identification. Fifty pieces of self-curing resin and thermosetting resin artificial eyes were produced. The artificial eyes in each group were randomly divided into five groups, and were cleaned respectively with clear water, volume fraction of 75% ethanol, Boston SIMPLUS, polident and toothpaste. After the completion of the cleaning, the test piece was conducted residual biofilm culture. The clearance effects of different processing modes were evaluated using colony counting method. RESULTS AND CONCLUSION: Eighty-four specimens were submitted for inspection, of which 49 were positive. The Staphylococcusaureus separation rate was 14.29%.Staphylococcus epidermidis separation rate accounted for 13.10%. Maxwel Corynebacterium separation rate accounted for 7.14%. When water, Boston SIMPLUS and toothpaste were used for cleaning, theStaphylococcus aureus colony number in the self-curing resin group was higher than that in the thermosetting resin group (P< 0.05); when ethanol and polident were used for cleaning, there was no difference in the Staphylococcus aureus colony number between these two groups. In self-curing resin, the colony count in the clear water treatment group was higher than that in the other treatment groups (P < 0.05). The colony count in the ethanol treatment group was lower than that in the Boston SIMPLUS group (P < 0.05). There was no significant difference in the colony count between other groups. In thermosetting resin, the colony count in the clear water treatment group was higher than that in the other treatment groups (P < 0.05). There was no significant difference in the colony count between other groups. These results demonstrate that ethanol, Boston SIMPLUS, polident and toothpaste have better cleaning effects onStaphylococcus aureusbiofilms on the surface of two kinds of ocular prostheses than the clear water rinse. Overal, it is encouraged to clean the artificial eyes using polident and Boston SIMPLUS, in order to avoid the occurrence of microbial infection in the conjunctival sac after wearing ocular prosthesis.
