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.
3.Molecular markers of autophagy.
Acta Pharmaceutica Sinica 2016;51(1):33-38
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.

4.Monte Carlo simulation of the divergent beam propagation in a semi-infinite bio-tissue.
Journal of Biomedical Engineering 2013;30(6):1209-1212
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.

5.Perioperative treatment strategy for colorectal liver metastases
Chinese Journal of Digestive Surgery 2015;14(6):445-448
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.

7.Immunological impact of autologous peripheral blood stem cell infusion on lung adenocarcinoma
Chinese Journal of Tissue Engineering Research 2017;21(9):1402-1407
BACKGROUND: Although clinical methods for autologous peripheral blood stem cell separation and identification arerelatively more, there is no unified standard. Moreover, little is reported on immune effects on lung adenocarcinomaduring autologous peripheral blood stem cell transplantation.OBJECTIVE: To study the effect of autologous peripheral blood stem cell transplantation on immunological function oflung adenocarcinoma rats by exploring the separation and identification methods of autologous peripheral blood stemcells.METHODS: The mononuclear cells were isolated from the peripheral blood of Wistar rats by density gradientcentrifugation method and then identified. Eighteen Wistar rats were randomly divided into routine treatment group andcell transplantation group, with nine rats in each group. Animal models of lung adenocarcinoma were established in therats, and underwent no treatment in the routine treatment group but injection of autologous peripheral blood stem cellsuspension (0.2 mL, 2.5×106/L) via the tail vein in the cell transplantation group. Immune indicators were detected in twogroups after treatment. Three rats from each group were anesthetized and scarified at 4, 10, 14 days after treatment,respectively. Afterwards, we detected the effects of autologous peripheral blood stem cell transplantation onimmunological function of lung adenocarcinoma rats.RESULTS AND CONCLUSION: Newly isolated mononuclear cells from rat peripheral blood showed a round or ovalshape and were relatively small in size. After 5 days of culture, autologous peripheral blood stem cells grew rapidly, andthe round cells began to spread to both ends and became spindle-shaped, thereby forming small colonies. Autologousperipheral blood stem cells induced in vitro experienced three stages successively: cell arrest, logarithmic and plateauphases. Flow cytometry showed that sorted cells were identified as autologous peripheral blood stem cells by expressingCD90, CD133 and Flk-1. After 4, 10 and 14 days culture, the expression of CD133 increased first and then descended,and Flk-1 showed an increasing trend. Compared with the routine treatment group, the expression of tumor necrosisfactor-α induced protein 6 in the cell transplantation group was significantly higher (P < 0.05), while the expression ofnuclear factor κB was significantly lower (P < 0.05). In conclusion, the isolation and identification methods of autologousperipheral blood stem cells are simple and can be used to secrete a large number of nutritional factors in the treatment oflung adenocarcinoma, which can enhance body immunity in the treatment.
