A novel series of bis-nicotine derivatives (3a-3i) were designed, synthesized and evaluated as bivalent anti-Alzheimer's disease agents. The pharmacological results indicated that compounds 3e-3i inhibited both acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) in the micromolar range (IC50, 2.28-117.86 micromol x L(-1) for AChE and 1.67-125 micromol x L(-1) for BChE), which was at the same potency as rivastigmine. A Lineweaver-Burk plot and molecular modeling study showed that these derivatives targeted both the catalytic active site (CAS) and the peripheral anionic site (PAS) of AChE. Besides, these compounds could significantly inhibit the self-induced Abeta aggregation with inhibition activity (11.85%-62.14%) at the concentration of 20 micromol x L(-1).

Objective By comparing the medical complaints and disputes between the two tertiary general hospitals in Beijing and Lhasa, this paper proposed on how to build a harmonious doctor-patient relationship.Methods A study of annual reports of these two hospitals analyzed descriptively patient complaint rate, rate of medical disputes registered for court jurisdiction, makeup of medical disputes, and their solutions.Results In 2016, the patient complaint rate, and rate of medical disputes registered for court jurisdiction were 3.5/10 000 and 12.4/10 000 respectively, much higher than 0.8/10 000 and 1.1/10 000 of the Lhasa counterpart hospital.A significant gap was also found in the makeup of medical disputes, their solutions, and role of hospital leadership between the two hospitals.Conclusions Beijing is recommended to appoint hospital leader on duty, to assist in handling medical complaints and disputes, and ease doctor-patient contradictions.Lhasa is recommended to improve the medical dispute handling mechanism, improve medical service competency and management.

Objective:To detect the expressions of survivin, galectin-3 and thyroid peroxidase in papillary thyroid microcarcinoma ( PTMC) and cancer adjacent normal tissue to explore the clinical significant.The correlations between the expressions of survivin,Gal-3 and TPO with BRAFV600E gene mutation in PTMC were analyzed.Methods: The expressions of survivin,Gal-3 and TPO were measured by immunohistochemical ( IHC ) method in 56 cases of PTMC tissue and adjacent normal tissue; BRAFV600E mutation was detected by PCR amplification and subsequently sequencing.Chi square test was used to analyse the relation in the expression rates of survivin,Gal-3 and TPO and BRAFV600E gene mutation.Results:The survivin and Gal-3 were strongly expressed but TPO was negatively expressed.The survivin and Gal-3 were negative in adjacent normal tissues but TPO was expressed.There were sig-nificant differences in the expression rates of survivin, Gal-3 and TPO between PTMC tissue and adjacent normal tissue (all P<0.001).The BRAFV600E mutation rate (32.1%) and the expression rates of survivin,Gal-3 and TPO in PTMC tissue were found to be positively related to lymph node metastases (P=0.009,P=0.025,P=0.007,P=0.008),and negatively related to gender and age (all P>0.05).There were no correlation was found between the expressions of survivin,Gal-3,TPO and the BRAFV600E gene mutation in PTMC(all P>0.05).Conclusion: The strong expressions of survivin and Gal-3,the mild expression of TPO and BRAF mutation may be important in the development of PTMC,and the detection of BRAFV600E gene mutation and the expressions of survivin, Gal-3 and TPO could be used to the judgment of pathogenetic condition and prognostic outcomes.

Objective:To investigate the value of the three-dimensional CT reconstruction by computer photo process system for laryngeal carcinoma and control study with pathologic feature. Methods: Fifty patients with laryngeal carcinoma were scanned by helical CT which photos were three-dimensionally reconstructed with a photo processing system,and the images were compared with pathologic feature.Results:Clear three-dimensional photo of the laryngeal was obtained through the reconstruction of the helical CT.The images could be circular fully around the axis of X,Y and Z in order to find the best view of the diagnosis.Ninety-six percentage of the TNM stage of patients according to the images of three-dimensional reconstruction were consistent with the TNM stage after operation.The safe edge was obtained in 98% of the surgery for patients.Good correlations were showed in the images of the three-dimensional reconstruction of the larynx and pathologic specimens.Conclusion:Good consistent of the three-dimensional images of the larynx with pathologic specimen were useful for diagnosis,operation design and education.
7. Molecular detection and genotyping of human papillomavirus
Chinese Journal of Oncology 2018;40(10):729-735
The development of cervical cancer is associated with persistent infection of high-risk human papillomavirus. The detection and genotyping of HPV could be used to evaluate the epidemiology of HPV infections, monitor HPV vaccine efficacy, and screen cervical cancer. There are a lot of commercially available molecular tests for HPV, based on different methodologies and detection systems. In principle, it mainly includes two categories, namely signal amplification and target amplification. Most of them are based on PCR amplification, such as fluorescent PCR, PCR-reverse hybridization, etc. The performances of detection reagents are different. In addition, HPV genotyping assays based on next-generation sequencing and quantitative HPV detection kits are developed. However, only a small number of commercial assays have been clinically verified. A large number of assays which may bring greater values in the screening of cervical cancer are needed to be clinically validated.

Objective To analyze the outcome indexes selected in the randomized controlled trials(RCTs)on traditional Chinese medicine(TCM)for skin rash caused by EGFR-TKI.Methods Seven databases were researched and the literature was screened according to the inclusion and exclusion criteria,then summarize and categorize outcome indexes to calculate frequency of outcomes and analyze.Results 46 out of 2241 papers were included.The outcome indexes of 40 RCTs were mainly divided into seven categories,that is physical symptoms/signs(37.97%),quality of life(17.65%),safety indicators(13.37%),traditional Chinese medicine symptoms/syndromes(16.58%),long-term prognosis(1.60%),blood biochemical index(9.09%)and others(3.74%).Problems as follow:First,there is a high risk of clinical trial bias in the treatment of EGFR-TKI-associated rash with TCM.Besides,the measurement time points was largely different with the severity of rash not considered.What's more,oversimplify the reports of compound outcome indicators and safety evaluation,lack of treatment time window and full process observation.Last,grading criteria for rash were inconsistent and the function of quality of life assessment tool was relatively simple.Conclusion At present,the use of outcome indicators has not been standardized in the RCTs for skin rash related EGFR-TKI by TCM,and relevant construction work should be carried out in the future to build a core index set with the characteristics of TCM treatment.
