Objective To evaluate the clinical features of nasopharyngeal carcinoma with different sur英文摘要>=rival time and to analyze the factors associated with prognosis improvement.Methods Three hundred and fifty three patients with nasopharyngeal carcinoma treated in our hospital from January 2000 to April 2002 were analyzed retrospectively.They were divided into three groups based on their survival time.One hundred and forty five patients were divided into A groups whose overall survival time were less than five years.Sixteen patients were included in B group whose overall survival time were greater than or equal to five years and less than ten years,and the other one hundred and ninety two patients were divided into C groups whose overall survival time were greater than or equal to ten years.The clinical features were compared and factors associated with survival were identified.Results The 5 and 10 years overall survival rates of the 353 nasopharyngeal carcinoma patients underwent radiotherapy were 58.924％ and 54.391％ respectively.Curative effect of early nasopharyngeal carcinoma was better.Cox regression analysis identified age,N stage,combined with chemotherapy or not and complete remission rate of nasopharynx and neck lymph were independent prognostic factors.Conclusion For nasopharyngeal carcinoma patients,early detection,early treatment,rational comprehensive treatment and complete remission after treatment and complications prevention are important.

Objective To evaluate the therapeutic effects of platinum alone chemotherapy combined with radiotherapy for esophageal carcinoma without operation.Methods Form April 2008 to February 2010,47 initial treatment patients with esophageal carcinoma were treated by platinum alone chemotherapy (cisplatin or nedaplatin 20 mg/m2,one times per weeks) and conventional fractionated radiation therapy (200 cGy per fraction,2 times per day,5 days per week,to a total dose of 6 000-7 000 cGy).Results 1-,2-,3-,4-year overall survival rates were 63.83 ％ (30/47),40.43 ％ (19/47),38.30 ％ (18/47),30.77 ％ (4/13).4-year survival rate of 13 cases with lymph node metastasis was 0,it was lower than that of cases without lymph node metastasis (40 ％,4/10),the difference was statistically significant (x2 =6.295,P =0.012).The 3-year survival rates in cisplatin or nedaplatin combined with radiotherapy group were 31.25 ％ (5/16) and 41.94 ％ (13/31),the difference was not statistically significant (x2 =0.510,P =0.475).Conclusion Low doses of platinum alone chemotherapy combined with radiotherapy for the treatment of esophageal cancer are safe,but long-term efficacy needs to be confirmed in larger clinical trials.

The proto-oncogene, c-kit gene, widely expresses on the mast cell, melanoeyte, haemopoietic stem cell, intestinal cell of cajal and germoeyte. Recent researches have revealed the relationship between the e-kit gene and the carcinogenesis, proliferation, infiltration and metastasis of some malignant tumor. This article aimed to make a review of its biological function, lab and clinical research advancement in the digestive tract tumor.

Cholesterol is an essential nutrient for human body.Dietary cholesterol comes from animal sources,including eggs,pork and others.A number of epidemiological and experimental studies showed that too much intake of cholesterol or consumption of more than 1 egg per day would slightly elevate blood cholesterol level.Results of studies in different areas and populations suggested that there is a lack of sufficient evidence to support the association between cholesterol intakes or egg consumption and cardiovascular disease incidence or deaths.

Objective To evaluate the clinical efficacy of platinum-based chemotherapy combined radiotherapy for cervical cancer.Methods From October 2008 to June 2010,61 patients with cervical cancer were treated by radiotherapy( conventional external radiation and after-loading brachytherapy,to a total dose of 8000- 8500 cGy)combined platinum-based chemotherapy (cisplatin or nedaplatin 20 mg/m2,one times per weeks) in our department.The clinical efficacy and side effects were evaluated.Results Among 61 patients,the short-term effective rate was 100％ ( 61/61 ) and 1-year survival rate was 85.2％ ( 52/61 ).There was no significant difference between cisplatin group and nedaplatin in 1-year survival rate ( 84.6％ vs.85.7％,x2 =0.014,P=0.095).Arrest of bone marrow at Ⅰ,Ⅱ,Ⅲ and Ⅳlevel occurred 5,24,5 and 1 patients in the cisplatin group,and 6,12,3 and 3 patients in the nedaplatin group.There was also no significant difference between these two groups in great mass side effects induced by chemoradiotherapy (x2 =6.402,P =0.171 ).Conclusion It is worth practising of platinum-based chemotherapy combined radiotherapy for cervical carcinoma.The side effects induced by chemoradiotherapy is low.

Objective To study the effects of treating limbs pain of patients with depression after cerebral apoplexy with self-designed hemiparalysis-washing formula.Methods 80 patients with limbs pain after cerebral apoplexy in our hospital from May 2013 to November 2013 were recruited into a control group and a treatment group randomly,40 patients in each group.The control group was treated with 30mg edamvone and 100ml 0.9％ sodium chloride or 0.5％ glucose injection,Ⅳ in 30min,and twice daily.Meanwhile,regular functional rehabilitation training was adopted for the patients.The treatment group was additional treated with self-designed hemiparalysis-washing formula on the basis of the control group.VAS,HAMD-24,MESSS,STREAM and therapeutic effects were evaluated in both groups after one month treatment.Results ① clinical therapeutic effects comparison:the total effective rate was 90％ and 70％ in the treatment group and the control group respectively,with statistical difference between the two groups (t=3.58,P＜ 0.01).② VAS,HAMD-24,MESSS,STREAM comparison:VAS,HAMD-24,MESSS,STREAM score was (2.28 ± 0.54)、(11.34 ± 3.02)、(13.49±4.27)、(44.76±20.71)in the treatment group respectively,and(2.90 ± 0.75) 、(14.24 ± 3.35)、(17.55 ±4.91) 、(34.56 ±15.56) in the control group respectively.Both groups showed obviously improvement than the before treatment,and the effects were better in the treatment group than the control group (all P＜0.05).Conclusion Self-designed hemiparalysis-washing formula improve limbs pain in patients with cerebral apoplexy and relieve their depression.

Objective To evaluate the value of magnetic resonance imaging in rheumatoid arthritis(RA) of the knee and compare with radiography.Methods 34 cases of RA of the knee were performed MRI and radiography.Enhanced MRI scans were obtained in 13 knees.Results On MRI there were bone erosion in 34 knees,subchondral sclerosis in 21 knees,meniscus destruction in 22 knees,cartilage damage in 15 knees,tibia movement in 10 knees,posterior cruciate ligament dragged in 8 knees.Pannus adhesion,proliferation synovium and joint effusion were showed on enhanced MRI in all of the 13 knees.On radiography bone erosion was showed in 1 knee,subchondral sclerosis in 11 knees,joint space stricture in 16 knees,tibia movement in 8 knees.Conclusion MRI is much better than radiolgraphy for diagnosis of RA of the knee.

OBJECTIVEThis study aimed at using cone beam computed tomography (CBCT) to study the influence ofprolonged unilateral posterior teeth loss on bilateral condylar morphology.

METHODSThe CBCT images of 30 patients withprolonged unilateral posterior teeth loss and 30 healthy people as controls were corrected. Mimics 15.0 software was used tomeasure volume, area, distance, and bone density of condyle. The results were statistically analyzed.

RESULTSThe volumeand bone density of condylar head and the entire condyle on missing teeth side were less than the contralateral side (P<0.05).The area and bone density of condylar transverse plane were greater than the contralateral side (P<0.05).

CONCLUSIONAfter prolonged unilateral posterior teeth loss, adaptive reconstruction occurs in the bilateral condyles, and condyle of missing teethside is smaller than the contralateral side.

Objective To evaluate the clinical effectiveness and the major toxic effect of radiotherapy combined with docetaxol and cisplatin respectively in the treatment of locally advanced non-small cell lung cancer (NSCLC).Methods 98 patients with locally advanced NSCLC were randomly divided into two groups.All of the patients were treated with 3D-CRT.One group was treated combined with docetaxel,20mg/m2,every week,totally 6 times.The other group was treated combined with cisplatin,30mg/m2,every week,totally 6 times.The total dose was 60 ～66Gy,2Gy/F,5 times each week for 5 ～7 weeks.The clinical effect and the major toxic effect between two groups were compared.Results The median survival time in group that treated with docetaxol was 17.2 months,median progression-free survival time was 13.5 months,and the 1,2 and 3-year survival rates of the patients were 78.6％,35.7％ and 19.5％ respectively.The median survival time in group that treated with cisplatin was 16 months,median progression-free survival time was 16.5 months,and the 1,2 and 3-year survival rates of the patients were 74％,34％ and 20％ respectively.The differences between two group were not stetisticelly significant( P ＞0.05 ).However,the side effect of the stomach and intestine and late radiation complication in group treated with docetaxol were slighter than those in group treated with cisplatin.Conclusion The clinical effect of radiotherapy combined with docetaxol in the treatment of locally advanced NSCLC was equal to radiotherapy combined with cisplatin.But radiotherapy combined with docetaxol has a slighter and acceptable toxic effect,which was worth the clinical application.

Objective To evaluate the efficacy and safety of induction chemotherapy and three-dimensional conformal radiation (3D-CRT) combined with endostar in the treatment of locally advanced non-small cell lung cancer (NSCLC).Methods Thirty patients with locally advanced NSCLC were enrolled and divided into observation group (15 cases) and control group (15 cases).In the observation group,the patients received induction chemotherapy and 3D-CRT combined with endostar.Chemotherapy:Vinorelbine 25mg/m2 on day 1 and 8,DDP 30mg/m2 on day 2 to 4.Endostar 7.5mg/m2 on day 1 to 14,which was used again after 7 days for 2 to 4 cycles.In the control group,the patients received induction chemotherapy and 3D-CRT at the same dosage.All patients were treated with 3D-CRT and the prescription dose was 60 ～ 68Gy per fraction.The responses were evaluated according to WHO criteria.The shortterm efficacy between the 2 groups was compared.Results The overall effective rate of the two groups were 66.7％ and 60.0％,respectively (P ＞ 0.05).The median progression-free survival time was 12 months in the observation group and 10 months in the control group.The median survival time was 20 months in the observation group and 18 months in the control group.The 1 year overall survival rate was 80.0％ in the observation group and 73.3％ in the control group(P ＞ 0.05).The main toxicities in the two groups were marrow suppression,gastrointestinal symptoms,acute radiation pneumonitis and acute radiation esophagitis.There was no significant difference between the two groups (P ＞ 0.05).Conclusions The combination of endostar with induction chemotherapy and 3D-CRT can improve the short-term efficacy rate of locally advanced NSCLC,the adverse events of which are tolerable,but the improvement is not significant in both groups.The result pending further randomized multi-center phase Ⅲ clinical study.
