钻石之光--山药

"每个人都能在自家的后院找到钻石",有人借用此言,把山药比做养生的钻石. 山药是一种薯科植物,它的根茎垂直而颀长,往往盈尺,生长在坚硬的山冈的土质中,旋转攀缘.阳光下,山药的叶子很美,颜色从浓到浅,绿得缤纷,但被我们称之为钻石的是它营养丰富的块状根茎.山药的外观看上去粗糙,细小密布的根须如刺如须,但削了皮,却洁白得如水生荸荠,分泌一些透明的黏液,柔滑得抓它不住,仿佛泥鳅从手中挣脱.     

Benefit of adjuvant chemoradiotherapy in patients with pathologically lymph node-positive and locally advanced gastric cancer

Objective This study aimed to compare the effectiveness of adjuvant chemoradiotherapy(CRT)and adjuvant chemotherapy(ChT)for T3–4/N+gastric cancer(GC)following D2/R0 dissection,and identify the specific subgroups that could benefit from adjuvant CRT.Methods All eligible patients were divided into the CRT group and ChT group.We assessed the survival outcomes and patterns of recurrence for each group,and determined the prognostic factors for survival by performing Cox proportional risk regression analyses.Results A total of 192 gastric cancer patients were included in the study.The estimated 3-year and 5-year disease-free survival(DFS)probabilities in the CRT and ChT groups were 52.9%vs.36.7%(P=0.024)and 41.2%vs.31.1%(P=0.148),respectively,and the estimated 3-year and 5-year overall survival(OS)probabilities were 82.4%vs.70.0%(P=0.044)and 52.0%vs.35.6%(P=0.022).Patients in the CRT group had a lower risk of locoregional recurrence than those in the ChT group(20.6%vs.34.4%;P=0.031).The subset analyses revealed that patients with stage N1–2 disease were more likely to benefit from adjuvant CRT than from adjuvant ChT(DFS:53.1%vs.36.4%;P=0.039;OS:53.1%vs.38.6%;P=0.036).Conclusion For locally advanced gastric cancer patients with LN+,adjuvant CRT showed superior survival benefits compared with adjuvant ChT alone.Patients with N1–2 achieved better survival from adjuvant CRT.     

苦参碱对HepG2细胞杀伤作用及机制研究

Objective:To investigate the death mode of human hepatoma cells exposed to matrine and the role of glutathione (GSH) and cytochrome c.Methods:The MTT test and Cell Death Detection ELISA were used to identify cell death mode and viability of cells exposed to matrine.The volume of intracellular GSH was detected by GSH reductase.Finally Western blotting was chosen to analyze the expression of cytochrome c and Caspase-9 in HepG2 cells treated by matrine.Results:The apoptotic cell death induced by matrine in Hep G2 cells dramatically increased in the time-,dose-dependent manner.Matrine can exhaust intracellular GSH effectively to change the redox state in cells.Furthermore it affect the cytotoxicity of matrine.Results of Western blotting showed that matrine induced the release of cytochrome c from mitochondria to cytoplasm,and then stimulate the cleavage of Cespese-9 in a time-dependent manner.Conclusion:Matrine induced apoptosis in Hep G2 cells through the mitochondrial pathway,and oxidative stress via depletion of GSH is directly involved in the apoptotic process.

The role of neuropathology in the management of progressive glioblastoma

Question

1. What are the most important diagnostic considerations in reporting progressive glioblastoma?

Target population

These recommendations apply to adults with progressive glioblastoma

Recommendations

Level III

For patients who undergo biopsy or neurosurgical resection at the time of radiologic or clinical progression, it is recommended that the pathologist report the presence and extent of progressive neoplasm as well as the presence and extent of necrosis within the pathologic material examined. Furthermore, to ensure the proper interpretation of progressive glioblastoma, it is recommended that the pathologist take into account the patient’s previous diagnosis and treatment, as well as the current clinical and neuroimaging features that have led to a second biopsy or resection.

Question

2. What techniques and ancillary studies are most useful in separating malignant progression from treatment effect?

Target population

These recommendations apply to adults with progressive glioblastoma

Recommendations

Level III

In the setting of prior radiation and chemotherapy, it is recommended to adhere to strict histologic criteria for microvascular proliferation and necrosis in order to establish a diagnosis of a glioblastoma. Immunohistochemistry and genetic studies are selectively recommended for distinguishing neoplastic cells from atypical reactive cells in progressive glioblastoma.     

Diagnostic significance of nasal eosinophilia in allergic rhinitis

Background

Nasal eosinophilia is one of the potential tests for substantiating the diagnosis of allergic rhinitis.

Objective

The aim was to establish the validity of nasal eosinophilia in allergic rhinitis, to study it's various clinical correlates and interpret it in context of skin sensitivity pattern.

Study Design

Prospective cased study.

Setting

Hospital based.

Patients

The patients were selected on the basis of history and clinical examination and were from the Himalayan region.

Intervention

Diagnostic.

Methods

The patients and the equal number of controls, were subjected to nasal smear for eosinophilia and intra-dermal skin tests to various allergeus.

Results

Overall, eighty percent of nasal smears were positive in various degrees among the cases. Around eighty-eight percent of cases showed both smear and skin test positivity, thereby signifying a high degree of harmony among them and further validating and confirming the diagnosis of allergic rhinitis.

Conclusion

Nasal eosinophilia was found to be a useful diagnostic test in allergic rhinitis, with a moderately high sensitivity and a high specificity.

The role of radiotherapy in the management of progressive glioblastoma

Question

Can re-irradiation (by using conventional radiotherapy, fractionated radiosurgery, or single fraction radiosurgery) be used in patients with progressive glioblastoma multiforme after the first adjuvant combined multimodality treatment with radiation and chemotherapy?

Target population

These recommendations apply to adult patients with progressive glioblastoma after first line combined multimodality treatment with chemotherapy and radiation.

Recommendations

Level III

When the target tumor is amenable for additional radiation, re-irradiation is recommended as it provides improved local tumor control, as measured by best imaging response. Such re-irradiation can take the form of conventional fractionation radiotherapy, fractionated radiosurgery, or single fraction radiosurgery.

Level III

Re-irradiation is recommended in order to maintain or improve a patient’s neurological status and quality of life prior to any further tumor progression.

Occupational exposure to endocrine disruptors and lymphoma risk in a multi-centric European study

Background:

Incidence rates of lymphoma are usually higher in men than in women, and oestrogens may protect against lymphoma.

Methods:

We evaluated occupational exposure to endocrine disrupting chemicals (EDCs) among 2457 controls and 2178 incident lymphoma cases and subtypes from the European Epilymph study.

Results:

Over 30 years of exposure to EDCs compared to no exposure was associated with a 24% increased risk of mature B-cell neoplasms (P-trend=0.02). Associations were observed among men, but not women.

Conclusions:

Prolonged occupational exposure to endocrine disruptors seems to be moderately associated with some lymphoma subtypes.

Comparative study of hearing improvement in type 1 tympanoplasty with and without canalplasty

Introduction

Widening of the external auditory canal is canalplasty. It is an intergral part of tympanoplasty, especially in anterior perforations and gives wide surgical access for proper repair.

Materials and methods

After elevating tympanomeatal flaps the canal is widened using conical cutting and diamond burrs following which entire tympanic annulus is visible and corresponds to an inverted truncated cone.

Results

Canalplasty gives 9 db gain in hearing compared to without canalplasty.

Conclusion

Canalplasty gives better visualization, better graft placement and better post-operative care.
