Objective To investigate the clinical characteristics,surgical strategy,pathological features and prognosis of pulmonary pleomorphic carcinoma.Methods The clinicopathological data of 23 patients with pulmonary pleomorphic carcinoma who underwent surgical resection from January 201 0 to March 201 4 in Tongji Hospital were collected.Results There were 1 6 male patients and 7 female pa-tients,with the male /female ratio of 2.3∶1 .The mean age of was 54(35 ~75)years old.A total of 1 7 pa-tients were heavy smokers and the mean smoking index was 688(400 -1 200).The initial main symptoms were cough,blood in phlegm and hemoptysis.It was difficult for fiberoptic bronchoscopy to confirm the di-agnosis.All patients underwent surgical resection,including 22 cases of radical resection and one case of biopsy.Microscopically,neoplastic epithelial cells and pleomorphic components were found in pulmonary pleomorphic carcinoma in 1 9 cases,and pleomorphic components only in the other 4 cases.Positive CK ex-pression in pleomorphic components was observed.The longest survival time was 1 8 months and the pa-tient was still alive.The median survival time was 1 2 months.Conclusion Pulmonary pleomorphic carci-noma usually occurs in middle-aged and elderly male smokers.Immunohistochemistry staining contribute to the diagnosis.The main treatment is surgery and the prognosis is poor.

This study was aimed to develop an HPLC method for simultaneous determination of five active components in Baihu and Guizhi decoction.Simultaneous determination of mangiferin,neomangiferin,glycyrrhizic acid,liquiritin,and cinnamic acid in Baihu and Guizhi decoction were conducted by HPLC-PDA under multiple UV wavelengths.An Waters xBridge BEH C18 Column (4.6 mm × 250 μm,5 μm) was used.The mobile phase was acetonitrile-0.01％ formic acid solution.The flow rate was 1 mL·min-1.The column temperature was kept at 24℃.The detection wavelength was set at 255 nm and 280 nm.The results showed that the linear range of mangiferin,neomangiferin,glycyrrhizic acid,liquiritin,and cinnamic acid was 66-1 976 μg (r =0.999 3),70-3487 μg (r =0.999 7),30-913 μg (r =0.999 5),35-1 734 μg (r =0.999 5),0.6-187 μg (r =0.999 8) in 70 min,respectively.The average recovery was between 95.29％ and 100.17％.It was concluded that the method was convenient,stable,reliable and accurate for simultaneous determination of the five components in Baihu and Guizhi decoction.It provided an evaluation method for the quality control of Baihu and Guizhi decoction and the research o its granules.

The caudal forelimb area (CFA) of the mouse cortex is essential in many forelimb movements, and diverse types of GABAergic interneuron in the CFA are distinct in the mediation of cortical inhibition in motor information processing. However, their long-range inputs remain unclear. In the present study, we combined the monosynaptic rabies virus system with Cre driver mouse lines to generate a whole-brain map of the inputs to three major inhibitory interneuron types in the CFA. We discovered that each type was innervated by the same upstream areas, but there were quantitative differences in the inputs from the cortex, thalamus, and pallidum. Comparing the locations of the interneurons in two sub-regions of the CFA, we discovered that their long-range inputs were remarkably different in distribution and proportion. This whole-brain mapping indicates the existence of parallel pathway organization in the forelimb subnetwork and provides insight into the inhibitory processes in forelimb movement to reveal the structural architecture underlying the functions of the CFA.
