Object To survey the worldwide medicinal plant resources of Illicium L Methods On the basis of herbarium, we studied on more than 10 000 speciemens of Illicium L from 121 Herbaria in 18 countries and the reviewed literature Results Fifteen species in Illicium L in the world belong to the medicinal plants, and they distribute in China, India, Burma and Vietnam In addition, the province scale distribution, habitat preference, and medicinal value are provided for each of the 15 medicinal plants Conclusion The medicinal plant resources of Illicium L from China are the most abundant in the world, and should be rationally exploited and widely utilized

The present paper reports a determination of copper, zinc and aluminium in caudate nuclei in 8 adult cadavers and in 15 newborn cadavers by atomic absorption spectrophotometry using the graphite furnace atomizer. The results showed that the normal content of copper in the adult caudate nucleus was 24.04?8.93mg/kg dry tissue, zinc 129.92+89.17mg/kg and aluminium 2.38?0.77mg/kg. In the newborn cadavers, the normal contents of copper zinc and aluminium were 11.00+5.49, 75.35+27.52 and 1.72?0.56mg/kg dry tissue respectively. These results indicate that the data Iisted above in adults are higher than in newborn in fants.

In order to study the light propagation in biological tissue, we analyzed the divergent beam propagation in turbid medium. We set up a Monte Carlo simulation model for simulating the divergent beam propagation in a semi-infinite bio-tissue. Using this model, we studied the absorbed photon density with different tissue parameters in the case of a divergent beam injecting the tissue. The simulation results showed that the rules of optical propagation in the tissue were found and further the results also suggested that the diagnosis and treatment of the light could refer to the rules of optical propagation.

Autophagy is a physiological process which delivers the mutant cytoplasmic proteins and dysfunctional subcellular organs into lysosomes for degradation to generate fuel in the deficiency conditions. It is mainly classified into macroautophagy, microautophagy and chaperon-mediated autophagy (CMA), as well as the selective autophagy such as mitophagy and aggrephagy. This review mainly introduces the key molecular markers of macroautophagy, CMA and mitophagy.

Lyme disease is continuing worldwide spread and its prevalence still presents raising tendency.The causative agent is Borrelia Burgdorferi(Bb) and the special biological intermedia is ixodid ticks(Ixodes scaputaris).The current study on the genetic strain of Bb and the interpretation of laboratory diagnosis(microscopic,immunologic and biomolecular test)results as well as the preparation of vaccine for the disease are made in this review.

Several resistant characteristics of Glycyrrhiza uralensis seeds were studied. The results showed that hard seed can resist attack from fungi or bacteria. It can endure high temperature for 4h at 80℃ and 10 min at 100℃, but when at 100℃ for 1 h it loses its germinating power. The seeds stored for 4 years do not reduce viability. After long period storage for 13 years,about 60% of the seed still retains its germinating power.

Liver metastasis is the leading cause of death from colorectal cancer.Surgical treatment is so far the best choice for the treatment of colorectal liver metastases (CRLM).However,how to suitably select an individualized chemotherapy in perioperative period and surgical time and tool is still under controversy.Therefore,the key factors of improving the prognosis of patients with CRLM include overall evaluation of the patients and their preoperative examination outcomes,dividing patients into different groups based on different therapeutic goals,understanding different therapeutic goals of each group,selecting suitable chemotherapy and targeted therapy,ensuring surgical time (synchronous or stepwise resection) and tools (minimally invasive or open surgery) through multidisciplinary team model.

Objective To explore the clinic effect of marvelon and estrogen on puberty dysfunctional uterine bleeding.Methods 50 patients were evaluated inclouding 20 patients treated by estrogen in estrogen(E) group and 30 patients treated by marvelon in progestin and estrogen(PE) group.Results The time when bleeding was stoped completely were (21.65?9.62) hours in E group and (13.68?5.67) hours in PE group(P

DNA methylation is one of the regulators on the expression of genes,and the expression of genes can be ”silenced” by hypermethylation of the tumor suppressor genes,which is in close relationship with carcinogenesis.Gastric cancer is caused by multiple factors and multiple genes alteration and prolonged interaction.among them ,There is considerable relation between the hypermethylation of the tumor suppressor genes and the gastric carcinogenesis.

As antigen-presenting cells, DCs are the most potent and unique,they can stimulate the primitive T cells. They play a major role in initiating the immune response. Tumor infiltrating dendritic cells (TIDCs) can reflect the antitumor immune capability of the host. The density of TIDC perhaps is associated with the prognosis in some cancers. The disablement of TIDCS is partly due to the phenotype they have. Perhaps it is the immunosuppressive factors secreted by tumor cells that have changed their phenotype.The studies about TIDCs provide the basis for DC-mediated antitumor immune therapy,and suggest the use of DC to treat tumors through different approaches.
