In order to clarify material basis of effective parts of liangxue tongyu prescription, blood-heat and blood-stasis rat model induced by dry yeast was established. The changes of rectal temperature, blood viscosity and plasma viscosity were used to evaluate the cooling-blood and activating-blood effects of liangxue tongyu prescription and its parts. Compared with the model group, the extract from liangxue tongyu prescription, its volatile oil and n-butanol part could significantly reduce rectal temperature (P<0.01), and also reduce blood viscosity and plasma viscosity to various degrees (P<0.01 or P<0.05). So volatile oil and n-butanol part were primarily identified as effective parts of liangxue tongyu prescription. By using GC-MS with normalization method of area to analyze volatile oil of liangxue tongyu prescription, 70 compounds were identified, accounting for about 92.54%, mainly as β-asarone, paeonol, α-asarone and shyobunone. 42 compounds such as peony glycosides, tannins, and iridoid glycosides were identified by HPLC-MS techniques and standard comparison. The study determined the effective parts of liangxue tongyu prescription and clarified the chemical composition providing the foundation for further studies on material basis of liangxue tongyu prescription.

Objective To investigate the effects of evodiamine on autophagy of human colon a cleno carcinoma lovo cells, and to explore the role and mechanism of autophagy which was induced by evodiamine (EVO). Methods MTT assay combined with the morphologic changes were used to observe the cell viability. Monodansylcadaverine was used to detect autophagy by fluorospectrophotometer and the confocal laser fluorescence microscopy respectively. Immunoblotting assay was used to observe the microtubule-associated protein 1 light chain 3. Finally, evodiamine combined with 3-methyladenine to detect the cell viability with MTT assay and the apoptosis with the flow cytometry, respectively.Results Evodiamine inhibited the viability of Lovo cells in dose-dependent manner ( P ＜ 0. 05 ), especially in 60 μmol/L that was obviously(60% ). Further more, the cell lysis and cell gap widened was observed by the light microscope. Evo triggered the autophagy, and after inhibition the autophagy by 3-MA, the killing capacities of the Evo was enhanced ( P ＜ 0. 01 ). However, autophagy prohibited the apoptosis pathways.Conclusions Evodiamine can trigger the autophagy, which might play a self-defense role in evodiamineinduced cell death. The cytototoxicity of evodiamine can be augmented by the autophagy inhibitors. The joint application of autophagy regulators with the chemotherapeutic agents might enhance the cell killing effects of chemotherapeutic drugs and show a potent role in cancer drug resistance.

The effectiveness and safety of acupuncture-moxibustion for the treatment of agrypnia was systematically reviewed. The clinical randomized controlled trial (RCT) of acupuncture-moxibustion for agrypnia were collected. The literature and document on acupuncture-moxibustion RCT for the treatment of agrypnia that published from January of 2001 to March of 2012 was searched with computer in PubMed, CNKI, Wanfang and VIP database. According to Cochrane Handbook 5. 1. 0, the bias risk and quality assessment were performed on every included trial and RevMan 5. 0 software was applied to make the Meta analysis. Totally 14 researches were included, involving 2662 cases. The Meta analysis showed that the differences of total effective rate between acupuncture-moxibustion and clinical routine treatment were significant [RR = 1.16, 95% CI (1.12, 1.19), Z = 9.32, P < 0.000 01]. The results indicate that total effective rate of acupuncture-moxibustion for agrypnia is obviously superior to that of clinical routine treatment, meaning clinical efficacy of acupuncture-moxibustion is served credit.

Aim To establish a new model of skin damage by u-sing vincristine to transgenic zebrafish (krt4:NTR-hKikGR).Methods Skin fluorescent transgenic zebrafish embryos after 24 h fertilization were treated with the 0.01~0.04 mmol·L-1 vincristine,and zebrafish skin cell ablation was investigated un-der fluorescence microscope after 24 h,at same time skin death cells were detected with TUNEL assay and image processed, then the protein expressions of KRT4, caspase-3 and p53 were assessed with Western blot. Results 0.02 mmol·L-1and 0.04 mmol·L-1vincristine could obviously induce zebrafish skin cell apoptosis(P<0.01) with statistically significant differ-ence compared with the control, and the same result could be accomplished in TUNEL assay. Results of Western bolt showed that vincristine could increase the embryos caspase-3 and p53 expression(P <0.01), while vincristine in high concentration might decrease KRT4 markedly(P<0.01). Conclusion Vin-cristine can induce damage on zebrafish skin with suppression KTR4,which can be used as a new skin damage model.

OBJECTIVETo investigate the morphological features and immunophenotype of unspecified peripheral T cell lymphoma with distinct lymphoid follicular growth pattern.

METHODSThree cases of peripheral T cell lymphoma with special pathohistological features were collected. Morphologic analysis and immunohistochemical staining for CD3, CD45RO, CD43, CD20, CD79a, cyclinD1, bcl-2, CD4, CD8 and S-100 were performed. PCR was used to study TCR gamma gene rearrangements.

RESULTSThe main symptoms of all the three patients with the primary sites of cervix and lower jaw. There were intermittent fever and skin rashes in the course of the disease. Morphological study showed lymphoid follicular reactive hyperplasia, mantle zone disappear, prominent infiltration of marginal zones by medium-sized tumor cells with clear cytoplasm and significant nuclear atypia. The immunophenotypic profile confirmed that they were T cell lymphomas. TCR gamma gene rearrangements were found in all the three patients.

CONCLUSIONIn some unspecified peripheral T cell lymphomas, the distinct follicular growth pattern and incomplete effacement of the lymph node architecture make it necessary to differentiate them from reactive hyperplasia, marginal zone B cell lymphoma, follicular B cell lymphoma and mantle cell lymphoma.

The aneurysms at the initial segment of splenic artery are rare. This paper aimed to investigate the methods to treat the true aneurysm at the initial segment of splenic artery by aneurysmectomy plus vascular reconstruction. Retrospectively reviewed were 11 cases of true aneurysm at the initial segment of splenic artery who were treated in our hospital from January 2000 to June 2013. All cases were diagnosed by color ultrasonography, computer tomography (CT) and angiography. Upon resection of the aneurysm, the auto-vein transplantation was performed in situ between the hepatic artery and the distal part of the splenic artery in 1 case; the artificial vessel bypass was done between the infra-renal aorta and distal portion of the splenic artery in 7 cases; the splenectomy was done in 2 cases; the splenectomy in combination with ligation of multiple small aneurysms were performed in 1 case. All cases were cured and discharged from the hospital 10-14 days after operation. A 1-14 year follow-up showed that 9 cases survived, and 2 cases died, including 1 case who died of acute myocardial infarction 2 years after aorta-splenic artery bypass operation and 1 case who died of acute cerebral hemorrhage 5 years after aneurysm resection and the splenectomy. Among 6 cases receiving aorta-splenic artery bypass, 1 gradually developed stenosis at anatomosed site, which eventually progressed to complete occlusion 2 years to 6 years after operation, without suffering from splenic infarction because the spleen was supplied by the short gastric vessel and its collaterals. The other 5 cases receiving aorta-splenic artery bypass and 1 case undergoing autologous vascular transplantation did not develop stricture or pseudoaneurysm at the stoma. Our study showed that the aneurysmectomy plus vascular reconstruction is a better treatment for aneurysm at the initial segment of splenic artery.

OBJECTIVETo evaluate the effects of infant formula containing palm oil on the nutrient absorption and defecation in infants.

METHODSA search in Cochrane Library, PubMed, OVID, Springer, China National Knowledge Infrastructure, Vip Chinese Periodical Database, Wanfang Chinese Periodical Database and Chinese Bio-medicine Database was performed to identify relevant English and Chinese language articles between January 1990 and March 2009. Two reviewers independently performed data extraction and appraised using Jadad instrument. Double data were input and analyzed by software of Review Manager 4.2 recommended by Cochrane Collaboration. Intestinal nutrient absorption, electrolyte content of fecal excretion, in vivo calcium deposition, and defecation were included as the target outcomes. These outcomes were evaluated as the combined standardized mean difference (SMD) and relative risk (RR) value and 95% CI of them.

RESULTSThirteen articles were included. Three articles meeting inclusion criteria were analyzed for the effects between infant formula containing palmitic acid at the Sn-2 positions and palmitic acid at the Sn-1, 3 positions; five articles were analyzed for the effects between infant formula containing palmitic acid at the Sn-1, 3 and without palmitic acid; another five articles were analyzed for the effects between infant formula containing palmitic acid at the Sn-2 positions and without palmitic acid. Absorption of fat and calcium was higher, the Ca(2+) of fecal excretion was lower when the infant formula provided palmitic acid at the Sn-2 positions or without palmitic acid than that determined when formula containing palmitic acid at the Sn-1 and Sn-3 positions was given (P < 0.01). The bone mineral content (BMC) and bone mineral density (BMD) increased at 3, 6 months when the infant formula without palmitic acid as compared with using the formula containing palmitic acid at the Sn-1 and Sn-3 positions (P < 0.01). The formation of calcium soaps in stool was reduced, the BMC increased when the infant formula provided palmitic acid at the Sn-2 positions as compared with using the infant formula without palmitic acid (P < 0.01). The incidence of soft stools was higher, and the incidence of hard stools was lower when the infant formula provided palmitic acid at the Sn-2 positions or without palmitic acid than that when formula containing palmitic acid at the Sn-1 and Sn-3 positions was used (P < 0.01).

CONCLUSIONAbsorption of fat and calcium was lower, the Ca(2+) of fecal excretion was higher, the BMC was reduced, the incidence of hard stools increased when the infant formula provided the palmitic acid at the Sn-1 and Sn-3 positions as compared with using formula contained palmitic acid at the Sn-2 positions or without palmitic acid. However, this conclusion should be used cautiously because of the limited quality of studies included into the analysis.
