Epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) is one of the most important targeted drugs for lung cancer patients carrying EGFR sensitive mutations.However,almost all patients that are effective to this treatment will eventually develop secondary resistance to EGFR-TKI.The most accepted mechanisms of resistance mainly include T790M mutation,MET amplification,PIK3CA mutation,down-regulation of PTEN expression and activation of Fas-transcription factor-κB.Recent years,many new drugs are developed to overcome this resistance.Although most of drugs are in the stages of cell or animal experiment,some new drugs get positive clinical results.

OBJECTIVE To evaluate the functional outcomes in patients undergoing supracricoid partial laryngectomy(SCPL).METHODS Twenty-one cases underwent supracricoid partial laryngectomy with functional reconstruction.In these cases.14 were glottic cancers(cricohyoidoepiglottopexy,CHEP),7 were supraglottic cancers(Cricohyokdopexy,CHP). RESULTS The mean time of decanulation was36.4 days,decannulation rate was 90.5%(19/21).All the patients recovered the function of speech and swallowing,but had variously hoarse.CONCLUSION The SCPL technique is effect in laryngeal functional reservation of laryngeal neoplasms.

Objective To explore the correlation between expression of nuclear factor kappa B (NF-kappa B) in peripheral blood monouclear cells(PBMC) and the severity of coronary artery lesion in patients with acute coronary syndrome(ACS). Methods The 81 patients were diagnosed with coronary heart disease, and all of them underwent immediate or selective coronary angiography(CAG) The nuclear protein level of activated NF-B was detected by Western blot and semi-quantity image analysis was done. Coronary angiograms were scored according to Gensini integration. The relationship between NF-κB and Gensini score was analyzed. Results The protein expression of NF-κB in PBMC in ACS group was significantly higher than that in stable angina group and control group (0.85±0.18 vs. O.75±0.21 and 0.71±0.23, F=3.72, P<0.05). The protein expression of NF-κB was not correlated with Gensini score(r=0.07, P>0.05). Conclusions The ACS patients have the activation of NF-κB in PBMC. The protein expression of NF-κB is not correlated with Gensini score, which does not suggest an implication of the severity of coronary artery.

AIM: To investigate the changes of Gq-phosphoinositide pathway in left ventricular tissue of rats with chronic heart failure in order to assess the role of this signal pathway in the formation of heart failure. METHODS: Male Sprague-Dawle rats were divided into three groups: control, chronic heart failure and benazepril therapy group. Chronic heart failure was induced with adriamycin. Rats in benazepril group received benazepril 10 mg?kg-1?d-1 and adriamycin at the same time. Hemodynamic measurement was carried out after 4 weeks. The expression of G? q/11 protein in left ventricle was detected by Western blotting analysis and activity of phospholipase C was measured by the method of hydrolysis of nuclear substrate. RESULTS: Compared with control group, the ?dp/dtmax in chronic heart failure group significantly decreased, and protein G? q/11 expression, basic and stimulated phospholipase C activity significantly increased (P

Background and purpose:Surgical operation is the main method in the treatment of laryngeal carcinoma, but different patients have different impacts on the survival time and the quality of life with different type of operation. This study was to analyze the methods of surgical treatment and its long-term effect of laryngeal carcinoma, to increase survival rates, laryngeal function reservation and reconstruction and improve life quality.Methods:A total mumber of 424 patients of laryngeal carcinoma treated with surgical treatment during between Jan. 2002 and Dec. 2012 were researched by clinical follow-up and data analysis. Surgical method: CO2 laser-assisted laryngeal microsurgery for laryngeal tumors for 50 cases, frontal partial laryngectomy or modiifed thyroid cartilage window partial laryngectomy without tracheostomy for 42 cases, vertical frontolateral partial laryngectomy for 119 cases, horizontal partial laryngectomy and extended subtotal laryngectomy for 22cases, anastomosis of pharynx and trachea for 4 cases, supra cricoid partial laryngectomy for 129 cases (CHEP of them for 103 cases, CHP for 26 cases), total laryngectomy for 58 cases, cervical lymph node dissection at the same term for 121 cases.Results:Partial laryngectomy without tracheostomy for 92 cases (21.7%), total laryngectomy for 58 cases (13.7%); decannulation rate was 86.5%, vertical frontolateral partial laryngectomy of them for 93.2%, horizontal partial laryngectomy of them for 90.9%,supra cricoid partial laryngeal of them for 82.2%; laryngeal function reservation rate for 86.3%; all patients did outpatient review and telephone follow-up, 9 cases loss to follow-up, a total of tumor recurrence, cervical lymph node metastasis and distant metastasis were 41 cases, mostly occurred in 1 year after surgery; death for 57 cases, relapse of them for 8 cases, cervical metastasis for 13 cases, pulmonary metastasis for 5 cases, hepatic metastases for 2 cases, brain metastases for 1 case, esophagus metastases for 1 case, pulmonary infection for 6 cases, acute renal failure for 2 cases, unknown reason for 19 cases, according to Kaplan-Meier to count survival rate, 3-year and 5-year survival rate were 90.7% and 84.1%, relapse and metastasis were the main causes of death.Conclusion:Surgical treatment is the main therapy mode of laryngeal carcinoma. We choose individualized surgical methods for patients according to tumor staging, invasion site, age, occupation and education background of patient, health condition and so on. On the premise that tumor is completely cut off, we always advocate function surgery and minimally invasive surgery, and adopt comprehensive treatment at the same time, in order to increase survival rates, lesson suffering and improve life quality as far as possible.

Objective To evaluate the significance of COLD-PCR in detecting KRAS mutation of pancreatic cancer and colorectal cancer patients. Methods First, set up COLD-PCR and compared the sensitivities of COLD-PCR/Sanger sequencing with PCR/Sanger sequencing using mixed cell lines ( KRAS wild-type cell line SW116 and KRAS mutant cell line SW480).Then, detected KRAS mutation of 20 formalin-fixed paraffin-embedded samples of pancreatic cancer and 39 formalin-fixed paraffin-embedded samples of colorectal cancer using PCR/Sanger sequencing and COLD-PCR/Sanger sequencing, respectively and compared the coincidence rate and consistency. Results The low detection limits of PCR/Sanger respectively. KRAS frequency detected by COLD-PCR/Sanger sequencing [75% (15/20)] in 20 cases of pancreatic cancer was higher than that detected by regular PCR/Sanger sequencing [40% ( 8/20 ) ,x2 =5.013, P < 0.05]. KRAS frequency detected by COLD-PCR/Sanger sequencing [44% (17/39)] in 39 cases of colorectal cancer was higher than that detected by regular PCR/Sanger sequencing [31% (12/39) ,x2 =1. 372, P = 0. 174]. The coincidence rate of these two methods was 0. 730 and the difference had no statistical significance. The coincidence rate of detecting KRAS mutation was 65% in pancreatic cancer and the results showed a good correlation between two methods and the two methods had bad agreement in diagnosis (Kappa = 0. 364, P < 0. 05 ). COLD-PCR/Sanger sequencing could detect more cases of KRAS mutations from pancreatic caner than regular PCR/Sanger sequencing. This was because there were many non-tumor cells in pancreatic tumor tissue and COLD-PCR/Sanger sequencing was more sensitive than regular PCR/Sanger sequencing. The coincidence rate of detecting KRAS mutations was 87% in colorectal cancer and the results were showed a good correlation between two methods and the two methods had substantical agreement in diagonsis ( Kappa = 0. 730, P < 0. 05 ) . Conclusion COLD-PCR/Sanger sequencing is highly sensitive to screen KRAS mutation in pancreatic cancer and colorectal cancer patients.

OBJECTIVE: To explore the surgical methods for management of early-stage glottic carcinoma involved anterior commissure. METHOD: Fifty-eight cases of early-stage glottic carcinoma (T1, n = 23; T2, n = 35) treated with vertical frontolateral partial laryngectomy and frontal partial laryngectomy or modified window partial laryngectomy without tracheostomy were retrospectively reviewed. RESULT: All patients can swallow smoothly and phonate clearly after operation. And the extubation rate with vertical fronto vertical partial laryngectomy is 97.2%. Tracheostomy was performed in one case after operation because of dyspnea. The most common postoperative complication was subcutaneous emphysema which developed postoperatively in 6 patients, but subsided after discharge. Follow-up was conducted for 8 months to 7 years, recurrence was observed in 3 cases. The 3 and 5 year survival rates were 97.5% and 91.8% respectively. CONCLUSION To choose the optimal surgical method for patients with early-stage glottic carcinoma not only can reduce the risk of recurrence but also can save the laryngeal function and thus improves the quality of life.

This study was aimed to reveal the species characteristics of Chinese patent medicines for antitussive ef-fect and provide references for developing new drugs. This research targeted Chinese patent medicines for antitussive effect which were included in the Pharmacopoeia of the People's Republic of China and the New National Chinese Patent Medicines as well as those characterized by keywords such as cough cure, cough alleviating, antitussive effect, cough, persistent cough. The analysis was made on the species characteristics, such as the number of Chinese patent medicines for antitussive effect, license number, ethnomedicine patent medicines, drugs for children use, protection of varieties of traditional Chinese medicine, the number of drugs, the generic names of drug, and drug forms. The results showed that 684 Chinese patent medicines for antitussive effect collected in this research had ac-counted for 8.60% of the total 7 260 of Chinese patent medicines. A total of 7 450 license numbers were approved, and 33% of the Chinese patent medicines shares one license number. One Chinese patent medicine owns 16.6 li-cense numbers on average. Ethnomedicine patent medicines had 3 Tibetan prescriptions such as the Shiwuwei Chenxiang pill and 4 Mongolian prescriptions, such as the Siwei Tumuxiang powder. Drugs for children accounted for 14%, including 9 forms. The type of the generic names of drug reached 16 and most of them originate from abbrevia-tions of the main drug in prescription. The number of drugs in prescription ranges from 8 to 16. Chinese patent medicines for antitussive effect involved 16 forms, of which the proportion of the use of solid preparation was higher than the liquid preparation. It was concluded that Chinese patent medicines for antitussive effect were characterized by such advantages such as a variety of species, various forms, the reasonable number of drugs, considerable medicine retail market share and drug for children use which can meet the clinical needs, and meanwhile some prob-lems, such as a lack of criteria for the generic names of drug, the homogenization of fierce competition, and inade-quacy of ethnomedicine patent medicines.

Objective To evaluate the effect of comprehensive schistosomiasis control measures based on infection source control in plateau mountain areas of Yunnan Province. Methods From 2006 to 2004,four administrative villages were selected as test areas from plateau canyon and plateau basin endemic areas in Jindun Town,Heqing County,two villages each type,and the comprehensive control measures were implemented,including the examination and treatment of schistosomiasis,Oncomela?nia hupensis snail survey and control,health education,improving drinking water and lavatories,banning grazing,constructing sanitary pen of livestock,replacing cattle with machine,etc. The schistosome infection state and snail status in 2006 were treat?ed as the baseline information,and the effect of the comprehensive measures were evaluated. Results The infection rate of hu?man in plateau canyon areas decreased from 4.94%in 2006 to 0.06%in 2014,and that of livestock decreased from 1.11%to 0. In plateau basin areas,there was only 1 case of schistosomiasis found in Xiaolian Village in 2007,and no any other cases found in the other years,the infection rates of livestock dropped from 7.38%to 0. Compared with 2006,the snail areas in the two type areas decreased by 74.89%and 75.30%,respectively,meanwhile,the percentage of snail area,the occurrence rate of frames with snails,as well as the average density of living snails also decreased,and no infected snails were found since 2008. Xidian and Xinzhuang villages in plateau canyon area reached the criteria of schistosomiasis transmission controlled in 2009,and Xiao?lian and Kangfu villages in plateau basin reached the criteria of transmission interrupted in 2014. Conclusions The comprehen?sive schistosomiasis control measures based on infection source control can effectively control the endemic situation of schistoso? miasis in plateau areas of Yunnan Province. In the future,we should pay an equal attention to the infection sources control and snail control to consolidate and amplify the achievement of schistosomiasis control.
