Objective To observe the therapeutic effect of the new plan of concurrent capecitabine (CAP) and radiation therapy for hu-man cervical adenocarcinoma in nude mice. Methods The nude mice were injected with CAC-1 cells for the modelization of cervical ade-nocarcinoma. Before treatment,all mice with tumors were randomly divided into control group,CAP group,5-FU group,radiation group,CAP+ radiation group,5-FU+radiation group. According to the tumor size,mice were furtherly divided into large-size and small-size groups in the control group,CAP group,radiation group, CAP+radiation group. The change of tumor size,tumor growth percentage and the delay time of tu-mor growth were evaluated. Results The therapeutic effect of combining 2/3MTD CAP with 6 Gy radiation or fractionation 2 Gy × 8 times radiation was better than that of the control group,chemotherapy group and the radiation group. The difference was significant (P < 0.05). The restraint effect of the combining 2/3MTD CAP with 6 Gy radiotherapy was better than that of the combining 2/3MTD 5-FU with 6 Gy radiotherapy. Combining 2/3MTD CAP with fractionation 2 Gyx8 times radiation therapy was more efficient than Combining 2/3MTD CAP with fractionation 6 Gy radiation therapy. In combining therapy groups,the response of large-size tumors was more significant than that of the small-size tumors (P < 0.05),which had almost no obvious response. Conclusion Concurrent CAP and radiation therapy has obvious restraint effect on CAC-1 cervix adenocarcinoma in nude mice. The CAP and radiation therapy can promote the therapeutic effect to each oth-er. The therapeautic effect of the concurrent CAP and radiation therapy is affected by the radiation dose, radiation method and the tumor size.

Proteins extracted from two varieties of Chinese roses leaves were separated by two- dimensional polyacrylamide gel electrophoresis (2-DE) with immobilized pH gradient (IPG). Many difference proteins were isolated with molecular weights ranging 10-30 kDa and pI5-6. Three proteins of high levels observed in a gel were excised and identified using peptide mass fingerprinting and MS-MS. A summary of the identified proteins and their putative functions are presented. They are identified as eIF-5A、LEA protein and Hsp17. 5. Functions of these proteins in plant tolerance to high temperature were discussed.

ObjectiveTo screen mimetic HIV-1 neutralizing epitopes from plasma with high level neutralizing antibody,and to provide useful information for further study of the interaction between antigen and antibody.MethodsIn order to gain neutralizing antibody recognized mimotopes, we detected neutralizing antibodieslevelsof 11HIV-1infectedslowprogressorsbyPBMC-basedneutralization assays.High-titer HIV-neutralizing antibodies from plasma of SPs was used as the ligand for biopanning by phage-displayed random peptide library.Positive phage clones was evaluated by ELISA,sequenced,and analyzed for homology to HIV-1 env by local BLAST to deduce the neutralizing peptide.ResultsTwenty-two clones were obtained consistent with requirement through three rounds biopanning.After comparison analysis,twelve clones include C8 were obtained as mimotopes of neutralizing antibody,C40 located in gp41Ⅱ cluster with the highest titer by inhibition ratio may be as neutralizing epitope.Conclusion By the use of IgG antibodies from SPs to screen the phage random polypeptide library,one can acquire multiple phage mimetic peptides of HIV related antigen epitope.(Chin J Lab Med,2012,35:838-842 )

Objective To examine the expression of TLR7/8 in monocytes purified from HIV-1 infected individuals and to study its association with disease progression. Methods Sixty-three HIV-1 infected individuals and 18 normal controls were enrolled. Monocytes were purified by MACS system and RNA of them was extracted by RNA mini kit of QIAGEN company. TLR7/8 expression was tested by real-time RT-PCR with ABI7500. Results It was found that the expression of TLR7 was strongly correlated with absolute CD4 count (r =0.614, P＜0.01) , so was TLR8 (r =0.419, P＜0.01). The expression of TLR7 in slow progressor (SP) group was higher than that in HIV-1 infected patients group, AIDS patients group and normal group (P ＜ 0. 05 ) . HIV group and normal group were strongly higher than AIDS group (P ＜ 0. 05). It was no significant differentiation of expression of TLR7 between HIV infection group and normal control group. The expression of TLR8 in SP group and normal group were significantly higher than that in AIDS group (P ＜ 0. 05). The expression of TLR8 was no singnificantly difference between SP group and HIV group or normal control group, so was it between HIV group or normal control group and AIDS group. Conclusion The expression of TLR7/8 in monocytes from HIV-1 infected patients significantly correlated with disease progression.

Objective To observe the effects of Najia method of midday-midnight point selection for acute ischemic stroke (AIS) model rats onthe contents of NSE and S100B protein in serum. Methods SPF SD male rats were chosen to establish the models by middle cerebral artery bolt method. Rats were divided into blank group, sham-operation group, model group, channel-point group, and Najia method group by random number table method. Blank group, sham-operation group, and model group were in the absence of treatment, while the channel-point group received acupuncture treatment according to differentiation syndrome. Najia method group used Najia method of midday-midnight point selection to conduct acupuncture treatment once a day. Improvement of neural function and cerebral infarction volume were observed. The contents of NSE and S100B protein in serum were detected. Results Compared with model group, neurological function score, infarct volume and infarct volume percentage, and the contents of NSE and S100B protein in serum decreased in Najia method group and channel-point group (P<0.05, P<0.01). The effects of Najia group were generally better than the channel-point group. Conclusion Najia method of midday-midnight point selection can decrease the content of NSE and S100B protein in serum of AIS model rats, so as to achieve the effects of neuroprotection and treatment.

Objective To investigate the effects of prescription of nourishing blood and stretching of stoke (PNBSS) on the levels of TXB2 and 6-Keto-PGF1αin serum of patients with acute ischemic cerebrovascular disease (AICD);To discuss its action mechanism in AICD treatment. Methods Ninety patients with AICD were randomly divided into trial group and control group, 45 cases in each group. The control group received western routine treatment, while the trail group received the western routine treatment plus PNBSS, one dose per day, for one week. Rating scale of neurologic deficit was employed to evaluate treatment effectiveness. Venous blood was collected before the treatment and on the 3rd and 7th days of treatment. Levels of TXB2 and 6-Keto-PGF1αin serum were detected respectively. Results The score of neurologic deficit of post-treatment in two groups apparently decreased compared with baseline (P<0.01), and score of neurologic deficit in trial group on 7th day was lower than that of control group (P<0.05). The total effective rate in trial group was 93.3%, which was apparently higher than that of control group (84.4%). The level of TXB2 in serum and ratio of TXB2/6-Keto-PGF1α (T/P) in two groups on 3rd and 7th days remarkably decreased compared with baseline (P<0.01), while the level of 6-Keto-PGF1α in two groups on 3rd and 7th days was higher than that of baseline (P<0.01). Meanwhile, the level of TXB2 and ratio of T/P in two groups on 7th day were apparently lower than that of 3rd day (P<0.01), and the level of 6-Keto-PGF1αon 7th day was higher than that of 3rd day (P<0.01). The level of TXB2 in serum and ratio of T/P on 3rd and 7th days in trial group were apparently lower than that of control group (P<0.01, P<0.05), while the level of 6-Keto-PGF1α on 3rd and 7th days in trial group was apparently higher than that of control group (P<0.01, P<0.05). Conclusion One of the mechanisms of PNBSS for AICD appears to inhibit overavtivity of thrombocyte, and regulate the misadjustment of ratio of T/P.

OBJECTIVETo evaluate the safety and therapeutic effect of high-dose daunorubicin-based (HD-DNR) chemotherapy in the treatment of acute leukemia (AL).

METHODSThe clinical data of 25 AL patients, including 14 cases for induction chemotherapy, 8 for consolidation chemotherapy and 3 for reinduction therapy, which were treated with HD- DNR (DNR dosage of 90 mg/m(2)× 3 d) between June 2010 and August 2012 in our hospital were retrospectively analyzed, the adverse reaction of chemotherapy, especially cardiac toxicity and therapeutic effect were evaluated.

RESULTSMost of the adverse reactions were mild, including cardiac toxicity, and no patient discontinued therapy because of HD-DNR related toxicities. Grade 3 or higher adverse reactions occurred only in the infection (56%) and diarrhea (12%). Withdrawal or dose reduction due to strong adverse reactions was not observed in all patients. Adverse reactions of infections (92%), lower ejection fraction(52.6%), diarrhea (48%), nausea (36%), vomiting (36%), dental ulcer (36%) and myocardial ischemia (32%) were relatively more common. The median time of neutrophil count reached to ≥ 0.5 × 10(9)/L and platelet ≥ 20 × 10(9)/L were both 21 days(ranged 9-31 and 9-38 days). Nine patients were complicated with infections before chemotherapy and 14 after chemotherapy, mainly occurred in gastrointestinal tract and respiratory system. Gastrointestinal, liver and kidney toxicity was slight. The cardiac ejection decreased in 10 cases, but only 1 reached grade 2 without clinical symptoms. Of the 14 AL patients for induction chemotherapy, 13 achieved hematological complete remission. Eight patients received HD-DNR as consolidation chemotherapy remained complete remission, while 3 refractory/relapsed patients remained non-remission.

CONCLUSIONThe adverse reaction of HD-DNR based chemotherapy for AL treatment was mild, no obvious cardiac adverse reaction occurred. The treatment dose of DNR at 90 mg/m(2) × 3 d can be safely and effectively used to treat acute leukemia.
