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.

Objective To explore the relationship betw een injury age and expressions of erythropoietin (EPO ) and its receptor EPO R in the brain tissue of rats after cerebral injury. Methods Seventy-tw o rats w ere random ly divided into control group (36 rats) and cerebral injury group (36 rats). The rats w ere sac-rificed at 1, 2, 4, 8, 12, 24 h after cerebral injury (6 rats at each tim e point) and the brain tissues w ere extracted. The expressions of m RNA and protein of EPO and EPO R at different tim e points w ere de-tected by real-tim e fluorescent quantitative PC R and W estern bloting. Results The expressions of EPO and EPO R increased w ithin 24 h after injury. The expressions of m RNA and protein of EPO w ere relat-ed to the injury age, and the correlations w ere 0.875, 0.911, respectively (P<0.05). The expressions of m RNA and protein of EPO R w ere related to the injury age, and the correlation coefficients w ere 0.936, 0.905, respectively (P<0.05). Conclusion The expressions of EPO and EPO R increase gradually in the early stage of the rat’s cerebral injury, w hich are associated w ith the injury age and could be a useful value for estim ating injury age.

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

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.

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.

Objective:Peripherally inserted central catheter(PICC) has been application in clinical for many years,but the training in the knowledge about maintenance wasn't univesal systematically yet.To analyze the existed problems on the clinical peripherally inserted central catheter in washpipe technology and find out countermeasures. Methods: The self-made questionnaire was used to survey a total of 46 nurses in every department and make on-site operation demonstration. Results: Only 12 nurses' operation was completely correct and the correct rate was 26.1percent,which was related to the training,manager's attention,nurses' participate awareness. Conclusion: The training on nurses' operation of red tube needed to be strengthen.
