Schizophrenia is a chronic and debilitating mental disorder.Around 20%to 40%of patients do not respond well to normal antipsychotic medication,and are ultimately diagnosed with treatment-resistant schizophrenia(TRS),representing the most severe and challenging form of schizophrenia.Currently,clozapine is the standard treatment for TRS.Early identification and standardized treatment can be beneficial to patients with TRS by controlling acute-phase symptoms as soon as possible,reducing suicidal rate and improving their quality of life.Under the guidance of the Steering Committee,this consensus was formed after multiple discussions by 30 psychiatric experts and anonymous Delphi surveys including 17 consensus opinions on treatment-resistant schizophrenia,which cover risk factors and prevention,diagnosis and evaluation,standardized clozapine treatment and management of adverse reactions,treatment regimens for clozapine resistance and intolerance,and psychosocial intervention,etc.The consensus-making process also incorporated evidence-based medicine to help standardize and guide diagnosis and treatment for adults with TRS in China.

Objective To explore the clinial value of airbronchogram in diagnosis of peripheral lung cancer (diameter≤3). Methods Comparing study between thin section CT and pathology was done on 174 nodules (129malignant and 45 benigin) in 150 patients. Results Thin section CT showed 30 cases (23%) of airbronehogram in nodules,only seen in bronchioalveolocarcinoma, adenocarcinoma and squamous cell carcinoma (significance difference). Conclusion Airbronchogram in peripheral small nodules was a certain sign of malignant nodule. The sign suggested diagnosis of histologic types in lung center.

Objective To evaluate the value of X-ray stereoscopic localized biopsy in diagnosis of breast minute calcification.Methods X-ray stereoscopic localized puncture and biopsy in 50 cases with breast minute calcification were analyzed retrospectively.Results In 50 cases,there were 18 cases of breast cancer,in which 3 were carcinoma in situ,10 were in clinical stage Ⅰ,5 were in clinical stage Ⅱ.The other 32 cases were benign lesion,in which there were 6 fibroadenoma ,5 microcyst,1 intraductal papilloma,18 cystic hyperplasia,2 duct ectasia.Conclusion Calcification is an important manifestation in diagnosis of breast cancer,especially the early stage of breast cancer.X-ray localized biopsy is the first and useful method in detecting the position and quality of the caicification.

Objective To evaluate the value of X-ray stereotaxic puncture in the diagnosis of early breast cancer.Methods The X-ray manifestations of 53 cases of early breast cancer verified by pathology were analysed.Results In 53 cases,there were 23 cases of lumps,17 were simple calcification,8 nodes with calcification,12 asymmetry improved density with disorder structue,15 stellatesign,18 augmentation blood,3 conduit breakag.Conclusion Mammography with X-ray stereotaxic localized puncture is the first useful method in diagnosing the early stage of breast cancer.
