Smoke water and distillation liquid were used to treat the seeds of Trichosathes kirilowii and to study the effects of smoke water and distillation liquid on the seed germination and seedling growth of T. kirilowii. The results showed that germination rate, germination index and germination vigor of T. kirilowii all were significantly improved with the treatment of SW and DL treatment. The activity of α-amylase were significantly increased with the treatment of SW and DL at 1:2,000. SW and DL treatment showed no significant effects on the activity of SOD. The activity of POD were markedly enhanced under the treatment of SW (1:000) and DL (1:2,000). CAT activity were increased with the treatment of SW and DL at 1:2,000 while were inhibited by SW and DL at 1:500. Seedling height and root length were increased with the treatment of SW and DL (1:1,000, 1:2,000). SW and DL treaments improved the content of chlorophyll, and moreover with the concentration of SW and DL, the stimulatory were also increased. This work demonstrated that smoke water and diatillation liquid at 1:2,000 could stimulate the seed germination and seedling growth of T. kirilowii, and it provided the references for the study of seed germination technology.

Objective To evaluate the clinical efficacy of tacrolimus and cyclophosphamide (CTX) on lupus nephritis.Methods The clinical trials on treatment of lupus nephritis with tacrolimus and CTX published before October 2012 were searched at Cochrane library,PubMed,OVID,Wanfang database,Chinese Journal full-text Database,Chongqing Weipu Database by using the methods of Cochrane systematic review.At the same time the information from related journals,professional data and network were hand-searched.The homogeneous evaluation was performed by Meta-analysis.Statistical analysis of clinical data was performed by using Stata11 software.Results A total of 4783 reports were found,while only 9 papers (8 randomized controlled trials and 1 cohort study) met the inclusion criteria.Tacrolimus group got better complete remission ratio (Z =4.05,P ＜ 0.01),similar partial remission ratio (Z =0.44,P =0.661),and better overall remission ratio (Z =4.29,P ＜ 0.01) as compared with CTX group.There were no significant differences between tacrolimus group and CTX group in the incidence of infection (Z=1.75,P=0.081),renal damage (Z=0.88,P=0.38) and abnormal glucose metabolism (Z =1.91,P =0.070).Side effects such as liver function impairment (Z =2.65,P＜0.01),gastrointestinal discomfort (Z=2.31,P＜0.05),menstrual disorders (Z=3.88,P＜0.01),bone marrow suppression (Z =3.29,P ＜ 0.01) in tacrolimus group were lower than those in CTX group.Conclusions Compared with CTX,tacrolimus has better complete remission ratio and overall remission ratio,with less side-effects in the treatment of lupus nephritis.However,large scale,multicenter,well-designed clinical trials should be adopted to further confirm the conclusions.

Objective to construct the high titers rat Hes1 adenovirus expression vector (Ad-Hes1).Methods With the rat cDNA as a template,the Hes1 fragment was amplified by PCR,which constructed pShuttle-CMV-Hes1 shuttle plasmid by directly clone.Based on pShuttle-CMV-Hes1,pAdeno-Hes1 virus plasmid was constructed,pAdeno-Hes1 was transfected into 293 cells to package Ad-Hes1,virus titers were determined by modified TCID50.Hes1 was detected by Western blot after Ad-Hes1 infected with H9c2 myocardial cells.Results pShuttle-CMV-Hes1 shuttle plasmid and pAdeno-Hes1 plasmid were constructed successfully,with a general titer of 1.6 × 1011 PFU,Ad-Hes1 can be expressed in H9c2 myocardial cells,and its MOI value was 30.Conclusion Ad-Hes1 is successfully constructedand packaged,thus provide basis for further research on the protection effect of Hes1 on myocardium.

Objective To study the immunophenotypic features of NK/T cell lymphoma in children and its association with Epstein-Barr virus (EBV) infection. Methods Five cases of children′s NK/T cell lymphoma were studied. CD45RO, CD3?, CD56, CD20, TIA-1 and granzyme B were detected by immunohistochemistry staining for investigating immunophenotype. The expression of EBV-latent membrane protein (LMP-1) were detected by immunohistochemistry. EBV-encoded RNA (EBER1/2) were detected by in situ hybridization (ISH). Results CD45RO, CD3?, TIA-1 and granzyme B were positive in 5 cases, CD56 was positive in 2 cases, while CD20 negative in 5 cases.EBER1/2 positive in 4 cases and LMP-1 positive in 3 cases.Conclusions NK/T cell lymphoma in children is strong associated with EBV infection,and EBV infection may play an important role in the pathogenesis of children NK/T cell lymphoma.

OBJECTIVETo investigate a new method for the analysis of IR fingerprint spectra of Radix Glycyrrhizae.

METHODTwo indexes, common peak ratio and variation peak ratio, are used to compare the IR spectra of various Radix Glycyrrhizae samples, and the values are calculated by means of sequent analysis.

RESULT AND CONCLUSIONThe dual-index sequence method provides a good approach to discriminate Radix Glycyrrhizae samples of different species and geographical origins.

OBJECTIVETo investigate the effects of dendritic cells (DCs) transfected with survivin gene, and to observe the effective and specific anti-tumor immunological effect induced by modified DC in vitro.

METHODSSurvivin gene was transfected to DCs with liposomes. Survivin expression could be detected both in DCs cells and in cell culture with method of Western blot. Cytokines as well as cellular surface molecule such as IL-12, TNF-alpha, CD1 alpha, CD83, MHCII, CD80 and CD86 were detected. The competence of inducing human specific cytotoxic T lymphocyte (CTLs) was also detected with MTT.

RESULTSSurvivin expression could be detected both in DCs which were transfected with survivin cDNA and in cell culture superior. The IL-12 and TNF-alpha level was (265.2 +/- 32.7), (437.1 +/- 83.5) pg/ml, and much higher in transgened DC cells than blank DC cells (P < 0.05). CD1 alpha, CD83, MHCII, CD80 and CD86 was high expressed in survivin-DC cells, however, it was low expressed in blank DC cells. The lyse rate to gastric cancer cell, colon cancer cell and bile duct cancer cell was 65%, 77%, and 85% respectively, and these were much higher than those of blank DC cells.

CONCLUSIONSDCs transfected with survivin gene could induce specific cytotoxic T lymphocytes and strikingly raised DC cell's antigen present function, and have specific CTL killing activity.

OBJECTIVEA new pattern recognition method suitable for traditional Chinese patent medicine was established in this paper, which is named as the Dual index grade sequence pattern recognition.

METHODIn this method the quality gradation was defined mathematically relying on normal distribution. By this way samples can be clustered and classified depending on which quality gradation is wanted, and the grading samples quantitatively relative to quality can be performed simultaneously. Especially, the redundant information with respect to pattern recognition hiding in dual index sequences of samples can be removed effectively by applying the good grade sequences, which make the pattern recognition results accurate excellently. This approach possesses the advantages of both supervised classification and unsupervised cluster methods. Samples can be clustered and classified at the same time without any standard samples, and the operation is accomplished based on the good grade similar sequences themselves being as the classifying marks. Moreover, the subclasses in each class can be identified more subtly.

RESULTThe infrared fingerprint spectra of extracts of 27 kinds of Mingmu Dihuangwan pills and Zhibo Dihuangwan pills samples extracted with ethanol were analyzed with the method proposed in this paper. The results showed that these pills can be classified in their subclasses clearly, respectively.

CONCLUSIONThe Dual index grade sequence pattern recognition is a new and effective one for identifying complex biological products made from complex herbal medicines.
