Chinese prescription is composed of Chinese herbal medicines according to "seven compatible relations" and "sovereign, minister, assistant and courier" principles. There are many methods in the research on combination and composition of Chinese herbal medicines. These methods are classified into traditional model and modern model. For the time being, compatibility study of traditional Chinese herbal medicines has developed from traditional model to modern model. The traditional model mainly studies the effects and mechanisms of the whole and split formulae in medical crude drug level, while the modern model mainly studies the effects and mechanisms of Chinese herbal medicine compositions in components combination level. Moreover, quantitative analysis becomes probable by modern model method. Now, setting up of new components combination model and optimal composition methods will not only develop the combination and the composition of Chinese herbal medicines from medicinal crude drug level to components composition level, but also get new formulae which have clear components and effects, and action targets and mechanisms. It will effectively promote the development of Chinese medicine formula.

To investigate the classification and modeling of traditional Chinese medicine (TCM) syndromes in post-hepatitic cirrhosis by partial least-squares (PLS) method, and to study the clinical application of PLS method in TCM research.

Objective To investigate the effects of 2.45 GHz microwave on the apoptosis of HeLa cells and explore the underlying mechanism.Methods HeLa cells were divided into five groups randomly:control group,sham-irradiation group,and three irradiation groups exposed with 10,15 and 20 mW/cm2 2.45 GHz microwave for 10 min.Cell survival was tested by MTT assay,cell nucleus fashion was observed by a laser scanning confocal microscope,cell cycle distribution was measured by flow cytometry,and cell protein expressions were detected by Western blot.Results The cell survival in control group,shamirradiation group and low dose irradiation group had no difference but it became lower in the middle and high dose irradiated group(t =-16.47,-14.23,P ＜ 0.05).The abnormal rates of nuclear fashion in the low,middle and high dose irradiation groups were obviously higher compared with control group (t =9.37,11.25,8.47,P ＜ 0.05),while high dose irradiation group was higher than the low and middle dose group (t =15.32,10.25,P ＜0.05).The rate of HeLa cells in sub-G1 in the irradiation groups were higher than that in control group (t =15.24,22.31,10.69,P ＜ 0.05).The results of immunohistochemistry showed that the expression of Bax and Caspase-3 in irradiation groups was significantly increased,and the expression of Bcl-2 was decreased.Conclusions 2.45 GHz microwave can induce HeLa cells apoptosis with a positive correlation with microwave dose.

Objective To observe protective effects of allicin on heart and lung in aging mice induced by D-galactose, and try to explore the possible mechanism from the aspect of oxidative stress. Methods Fifty male Kunming mice were randomly divided into 5 groups:normal control group ( group C) ,model control group ( group D) and high-,middle-and low-dose of allicin groups ( H,M,L group) . The rats in group D,L,M and H were injected with D-galactose. At the same time,the rats in group L,M and H were injected with allicin. All of the injection lasted for 6 weeks. After that,athletic ability of the mice was evaluated by behavioral experiments. Malondialdehyde ( MDA ) content, superoxide dismutase ( SOD ) activity and total antioxidant capacity ( T-AOC) in the homogenate of heart and lung tissues were measured,and the expression levels of Bax and Bcl-2 were tested in heart and lung. Results Behavioral experiment showed that standing time on Rota Rod System and continuous running time on mice treadmill were significantly shortened in group D as compared with group C ( P<0.05) ,but those were prolonged in the allicin groups. Compared with group C,MDA content in homogenate of myocardium and lung tissues was significantly increased in group D (P<0.05),the activity of SOD was decreased (P<0.05) and T-AOC was decreased (P<0.05) . As compared with group D,MDA content in allicin groups was significantly decreased ( P<0.05) ,SOD activity increased (P<0.05) and A-TOC increased (P<0.05) in a dose-dependent manner. The results of immunohistochemistry showed that the expression of Bax was significantly increased in group D as compared with group C,and the expression of Bcl-2 was decreased. After the intervention of allicin,expression of Bax was decreased in group L,M and H as compared with group D, and expression of Bcl-2 was increased as compared with group D. Expression levels of Bax and Bcl-2 in lung tissues showed the same changing trend. Conclusion Allicin has a potential protect role on heart and lung in D-galactose-induced aging mice by increasing athletic ability,decreasing oxidative stress and decreasing cell apoptosis of myocardium and lung tissues.

ObjectiveTo introduce the new method of full reconstruction for Ⅰ to Ⅲ-degree finger defect.MethodsFor reconstruction of Ⅰ to Ⅱ-degree finger defect, the surgery procedure was as follows:Harvest part of nail,skin and dorsal part of distal phalanx from hallux to form a composite flap,and then the flap was transplanted to the finger stump to reconstruct the defect part of the finger.The design of the composite flap was according to the recipient part. For reconstruction of Ⅲ-degree finger defect, the skin included in the flap could be designed according to the recipient part, but the bone can only be harvested from the fibulodoral part of the hallux and far from the insertion of the extensor hallucis longus tendon, which means the length was limited.If the bone length was not enough,one bone mass with appropriate size and shape was harvested from the iliac bone and connected with the bone of the composite flap. Some cases of Ⅲ-degree finger defect were reconstructed by harvesting interphalangeal joints from the second toes to reconstruct distal interphalangeal joints(DIP). The bone defect was reconstituted by bone mass from the iliac bone to conserve the contour of the second toe.The hallux wound was covered by a local flap or free flap transplantation.ResultsOne hundred and eighteen cases (126 fingers) of Ⅰ-degree defect, one hundred and eighty-seven cases (201 fingers) of Ⅱ-degree defect and 90 cases (111 fingers) of Ⅲ-degree finger defect were applied full reconstruction. All the reconstructed fingers survived completely and the configurations were similar to real fingers. Followed up our work on 150 fingers from a number of patients, between 1 and 11 years after the original surgery.Total ranges of motion of the reconstructed fingers got to over 180°.The reconstructed DIP joints had the range of motion of 15°-40°. The donor halluxes and toes were conserved with the normal length,relatively primary appearance and full function. ConclusionFull reconstruction for Ⅰ to Ⅲ-degree finger defect has great advantages in that the reconstructed finger has very realistic configuration as well as ideal function and the donor hallux is conserve well.

OBJECTIVE To observe the effect of the autophagy and endoplasmic reticulum stress (ERS) in vascular smooth muscle cells (VSMCs) with hydrogen peroxide (H2O2). METHODS The VSMCs were incubated with different concentrations of H2O2(50, 100, 200, 400, 600, 800, 1200 and 1600 μmol · L-1)for 12 and 24 h. The cell viability was determined by MTT assay. The cell morphology was observed under an inverted phase contrast microscope. The expression of autophagy related protein ubiquitin binding protein p62 and microtubule-associated protein light chain 3(LC3)was detected by indirect immunofluorescence. Western blotting was used to detect autophagy related protein human coiled-coil myosin-like BCL2-interacting protein (Beclin-1),LC3 and mammalian target of sirolimus Rapamycin(mTOR),as well as the expression of endoplasmic reticulum stress(ERS)related protein glucose regulated proteins 78 ku(GRP78)and C/EBP homologous protein(CHOP). RESULTS MTT results showed that H2O2 inhibited the growth of VSMCs cells. The half inhibitory concentration (IC50) was 597.2±2.3 and(447.4±1.7)μmol·L-1 at 12 and 24 h,respectively. The results of the inverted phase contrast microscope showed that VSMCs in H2O2 group shrinked and turned into smaller round cells. The cell survival rate declined from(97.5 ± 0.1)% in normal control group to(74.4 ± 1.0)% and(56.8 ± 0.9)% in H2O2 400μmol·L-1 at 12 and 24 h, respectively. The results of the laser scanning confocal micro?scope showed that H2O2 400 μmol · L- 1 increased the expression of LC3 and p62 protein in a cytoplasmic time-dependent manner, and increased the colocalization of LC3 and p62,especially at 8 h. The results of Western blotting demonstrated that H2O2 increased the expression of ERS related protein GRP78 and CHOP,autophagy related protein Beclin-1 and LC3Ⅱ/LC3Ⅰ(P<0.01),and decreased mTOR(P<0.01)in VSMCs. CONCLUSION H2O2 induces autophagy through ERS in VSMCs.
