Objective To evaluate clinical features, diagnosis and treatment of anorectal malignant melanoma (ARMM).Methods The clinical data of 15 patients of ARMM in our hospital and 18 patients in the First Affiliated Hospital of China Medical University from 1990 to 2010 were reviewed.Twenty-five patients underwent curative surgical resection, 14 patients underwent abdominoperineal excision of the rectum (APR), and 11 patients underwent local excision (LE).Survival analysis was carried out.Fisher's exact test and Log-rank test was used to compare the effects of these two different surgical procedures.Results ARMM had a female predominance, the mean age was 22 -77(54.5 ± 7.6) years.The major clinical signs included hematochezia, anus pain.The misdiagnosis rate was 67% (22/33).The average tumor size was (3.5 ±1.7) cm.Thirty-one petients(94% ,31/33) had ARMM within 5 cm from anus margin.Mean survival time was (14.0 ± 6.5)months.The overall 1-,3-,and 5-year survival rates were 48% ,22% , and 10% , respectively.Local recurrence after curative LE was higher than APR (LE,64% vs APR, 21% , P = 0.049) , The overall 3-year disease-specific survival rates after curative LE was not significantly different from that of APR (LE, 28% vs APR ,31%, x2 = 0.268, P = 0.582).Conclusions Anorectal malignant melanoma has a high rate of misdiagnosis.Radical resection could not prolong the survival time significantly in anorectal malignent melanoma patients.

Objective To evaluate the adaption,effectiveness,dose,complication of the treatment for cranio pharygiomas with gamma knife surgery.Methods Gamma knife surgery was performed in 41 patients.Patients with mixed solid and cystic tumors were treated with stereotaxic aspiration while six cases were treated with divergence surgery prior to gamma knife therapy.The central dose ranges from 17.1 ～40 Gy(29.6Gy in average).The patients were treated at 30%～50% equal dose curve with 6 ～14Gy of tumormargin dose(9.5Gy in average).The exposure dose of the optic nerve and optic tract is less than 10Gy.Results Of twenty-nine patients who were followed up from 6 to 100 months,sixteen had disappeared or decreased tumor,six had unchanged,two was performed craniotomy one year or three years after gamma knife surgery,and the remaining five were dead one year to three years.The tumor control rate was 75.9%(22/29).Conclusion The treatment of stereotaxic radiation with single and high dose is sensitive to most of the solid craniopharyngioma,and the treatment of stereotaxic resection combined with gamma knife surgery may be feasible for the recurrent mixed solid and cystic craniopharyngioma.

ObjectiveTo evaluate the effect and complication of whole γ-knife stereotactic radiotherapy on the non-small cell lung cancer and explore the value of γ-knife stereotactic radiotherapy in treatment of non - small cell lung cancer. Methods42 patients with non -small cell lung cancer:γ-knife radiotherapy patients ,4 ～ 8Gy once a day,five times a week,4 ～ 10times and 40 ～50Gy in total. ResultsThe overall response rate (CR + PR) in γ-knife was 71.4％. The1-,2-and 3-year survival rates were 95.5％, 59.5％, 33.3％. ConclusionCompared with conventional radiation,γ-knife stereotactic radiotherapy could achieve tumor dose escalation,and give the normal tissue better protection at the same time. It could improve the tumor control rate of non-small cell lung cancer,improve long survival rate,and so could reduce the radiation reaction.

This study is to investigate the effect of 8-prenylnaringenin (8-PNG) on osteoclastogensis of bone marrow cells and bone resorption activity of osteoclasts. Osteoclasts were separated from long bone marrow of newborn rabbits and cultured in alpha-MEM containing 10% FBS. 8-PNG was added into culture media at 1 x 10(-7), 1 x 10(-6), 1 x 10(-5) mol xL(-1), separately. 17beta-Estradiol (E2, 1 x 10(-7) mol x L(-7)) was used as positive control. T RAP staining and TRAP activity measurement were performed after 5 days, and the bone resorption pits were analyzed after 7 days. Annexin V staining for the detection of apoptotic osteoclasts was performed after 2, 4, 8, 12, 24, 36 and 48 h separately. The mRNA expression level of TRAP and cathepsin K (CTSK) was measured by real-time RT-PCR. 8-PNG significantly reduced the number of osteoclasts which was TRAP staining positive and with more than three nucleus, the area and number of bone resorption pits decreased obviously in 8-PNG-supplemented groups. The apoptosis rate peaked earlier in the 8-PNG-supplemented groups and the mRNA expression level of TRAP and CTSK decreased significantly. All these inhibitory effects were in a dose dependent manner, the highest effect was obtained by 1 x 10(-5) mol x L(-1) 8-PNG. 8-PNG inhibits bone resorption activity of osteoclasts by inducing osteoclast apoptosis and inhibiting the gene expression and enzyme activity including TRAP and CTSK, and restrains bone marrow cells to osteoclast differentiation.

This observation was to assess the treatment effects of free medial sural artery perforator muscle flap on foot reconstruction.Seven patients(6 men,and 1 woman;age 19 to 46 years,mean 33) with soft tissue defects on the foot underwent surgical procedures by using free medial sural artery perforator muscle flap.The coverage of the muscle flaps was performed by a meshed split-thickness skin graft.The donor site Was closed.Median follow-up Was 2.5 years(range 7 monks to 5.5 years).All the muscle flaps and skin grafts survived without major complications,and no morbidity was found at the donor sites.The muscle flaps seem to have advantage in blood supply,vascular anatomy and pedicle length,and may be helpful in the mpmr of soft tissue defects on the foot.

Seventy-five preschool children with hemoglobin content below 11 g/dl in kindergartens and nurseries were divided into five groups. The first, second and third groups were given 10 mg, 20 mg and 30 mg of iron in the form of ferrous sulfate syrup respectively every day for two months, while the fourth and fifth groups were given 100 mg ascorbic acid and 100 mg ascorbic acid plus 10 mg iron respectively every day for one month. The average hemoglobin content in the order of the five groups were 9.6?1.16, 10.6?1.34, 9.7?0.91, 9.7?0.85 and 11.0?1.86 g/dl respectively before treatment. After 1-2 months of iron or ascorbic acid therapy, the average hemoglobin contents raised to 12.0?.31, 12.0?1.06, 12.0?0.79, 11.0?1.86 and 12.7?1.37 g/dl respectively. There were highly significant differences (P

OBJECTIVE: Diterpenoids with a wide variety of biological activities from Anoectochilus roxburghii, a precious medicinal plant, are important active components. However, due to the lack of genetic information on the metabolic process of diterpenoids in A. roxburghii, the genes involved in the molecular regulation mechanism of diterpenoid metabolism are still unclear. This study revealed the complex metabolic genes for diterpenoids biosynthesis in different organs of A. roxburghii by combining analysis of transcriptomics and metabolomics. METHODS: The differences in diterpenoid accumulation in roots, stems and leaves of A. roxburghii were analyzed by metabonomic analysis, and its metabolic gene information was obtained by transcriptome sequencing. Then, the molecular mechanism of differential diterpenoid accumulation in different organs of A. roxburghii was analyzed from the perspective of gene expression patterns. RESULTS: A total of 296 terpenoid metabolites were identified in the five terpenoid metabolic pathways in A. roxburghii. There were 38, 34, and 18 diterpenoids with different contents between roots and leaves, between leaves and stems, and between roots and stems, respectively. Twenty-nine metabolic enzyme genes with 883 unigenes in the diterpenoid synthesis process were identified, and the DXS and FDPS in the terpenoid backbone biosynthesis stage and CPA, GA20ox, GA3ox, GA2ox, and MAS in the diterpenoid biosynthesis stage were predicted to be the key metabolic enzymes for the accumulation of diterpenoids. In addition, 14 key transcription factor coding genes were predicted to be involved in the regulation of the diterpenoid biosynthesis. The expression of genes such as GA2ox, MAS, CPA, GA20ox and GA3ox might be activated by some of the 14 transcription factors. The transcription factor NTF-Y and PRE6 were predicted to be the most important transcription factors. CONCLUSION This study determined 29 metabolic enzyme genes and predicted 14 transcription factors involved in the molecular regulation mechanism of diterpenoid metabolism in A. roxburghii, which provided a reference for the further study of the molecular regulation mechanism of the accumulation of diterpenoids in different organs of A. roxburghii.
