Radiotherapy and chemotherapy are the main treatment means for locally advanced squamous cell carcinoma of the pharynx and larynx, to guarantee efficacy and avoid the damage of radical surgery, so as to preserve the laryngeal function of swallowing and pronunciation.With the progressing of radiotherapy technology,concept of treatment and radiotherapy mode have been advanced constantly,that have prolonged the survival time and improved the quality of life.This study will review the progress of radiotherapy in the pharynx and larynx squamous cell carcinoma, investigate the improvement of radiotherapy technology and hypofractionated IMRT, and provide reference for reducing the toxicity and after effects of radiotherapy.

Chemotherapy with or without molecule-targeting agents is the primary choice for patients with unresectable metastatic coloreetal cancer. New treatment strategies like intermittent therapy and maintenance therapy may not inferior to treatment until progression or unacceptable toxicity in maintaining the benefit for patients who responded or had stable disease after the first-line therapy,and also can reduce the drug related side effeets and improve the quality of life.

Objective To investigate the possible role of mycobacterial infection in the pathogenesis of sarcoidosis.Methods DNA fragments of mycobacterial16S rRNA gene and the complex-specific insertion sequence IS6110of M.tuberculosis were detected by polymerase chain reaction(PCR)in formalin-fixed,paraffin-embeded skin biopsy specimens from12patients with sarcoidosis.Results Mycobacterial common sequence16S rRNA gene was found in6patients,among which5were further confirmed as M.tuberculosis,the other one was atypical mycobacteria.The IS6110DNA fragment amplified by PCR was confirmed by DNA sequencing.Conclusion The above findings suggest an aetiological role of mycobacterial infection,especially M.tuberculosis,in some patients with sarcoidosis.

Objective To summarize and analyze the failure reason of internal fixation operation in peritrochanteric fractures and propose appropriate prevention measures.Methods The clinical data of 229 patients with peritrochanteric fractures were retrospectively analyzed,the failure reason of internal fixation was analyzed by the univariate and multivariate Logistic regression analysis.Results The univariate analysis showed that the patients' age,gender composition,types of internal fixation had no significantly correlated with the failure of internal fixation (P ＞ 0.05) ; the Garden reset index,bone quality,fracture type and load time had significantly correlated with the failure of internal fixation (P ＜ 0.05).The multivariate Logistic analysis showed that load time was the independent risk factors for fixation failure (OR =13.515).Conclusion The weight-bearing time points should be selected according to the bone quality,fracture type,and degree of intraoperative reset,thereby reducing the risk of surgery failure.

Objective To study the effect of transmembrane tumor necrosis factor-alpha (TM-TNF-αt) on human cervical carcinoma HeLa cells,and explore the correlations with silencer of death domain (SODD).Methods The expression of proliferating cell nuclear antigen (PCNA) was detected by immunocytochemistry.The expression of SODD in human cervical carcinoma HeLa cells undisposed and after disposed with TM-TNF-α was detected by reverse transcription-polymerase chain reaction,and the influence of TM-TNF-α on human cervical carcinoma HeLa cells was analyzed.Results The positive rate of PCNA in undisposed human cervical carcinoma HeLa cells was 80.3％ (155/193),in human cervical carcinoma HeLa cells disposed with TM-TNF-α was 46.7％ (85/182),there was statistical difference (P ＜ 0.05).The cycle index of polymerase chain reaction in human cervical carcinoma HeLa cells was 28 times,the amplification product was disposed by 2％ agarose gel electrophoresis,the gray scale disposed by TM-TNF-α and undisposed human cervical carcinoma HeLa cells were 1.377 ± 0.170 and 0.815 ± 0.040,there was statistical difference (P ＜ 0.05).Conclusion TM-TNF-α has obvious cytotoxic effect on human cervical carcinoma HeLa cells in vitro which may due to its up-regulating the expression of SODD.
