Objective:To investigate the type and severity of skin adverse reactions induced by afatinib in the treatment of lung cancer, and to analyze their correlation with anti-lung cancer efficacy.Methods:A case-case-control study was conducted on lung cancer patients treated with afatinib in ZhongDa Hospital, Southeast University from December 2016 to January 2018. The type and severity of skin adverse reactions were evaluated in 76 patients with lung cancer based on the National Cancer Institute-Common Terminology Criteria for Adverse Events (NCI-CTCAE) Version 4.0, and these patients were divided into 3 groups according to the severity of skin lesions, including grade-0, -1, and -2/3 groups. The patients underwent chest computed tomography (CT) examination every 3 months, and the tumor response to afatinib was evaluated according to the Response Evaluation Criteria in Solid Tumors (RECIST) . Anti-lung cancer efficacy of afatinib was compared among the patients with different grades of skin lesions by using the Kruskal-wallis H rank sum test. Results:After treatment with afatinib, 44 of the 76 patients with lung cancer achieved stable condition or partial remission, and 32 experienced disease progression. Skin adverse reactions occurred in 69 patients, and manifested as acneiform lesions in 42 (55.3%) patients, paronychia in 35 (46.1%) , mucosal erosions in 30 (39%) , hair changes in 8 (10.5%) , and hand-foot syndrome in 6 (7.9%) . Improvement was achieved in 3, 7 and 34 cases in the grade-0, -1, and -2/3 groups ( n = 7, 19 and 50 respectively) , respectively. There was a significant difference in the response rate among the 3 groups ( χ2 = 6.117, P = 0.047) , and the response rate was significantly higher in the grade-1 and -2/3 groups than in the grade-0 group (both P < 0.001) , and higher in the grade-2/3 group than in the grade-1 group ( P < 0.001) . Conclusion:The treatment of lung cancer with afatinib can cause various types of skin lesions, such as acneiform lesions, paronychia, mucosal erosions, hair changes and hand-foot syndrome, and the higher the severity of the skin lesions, the more marked the anti-lung cancer efficacy of afatinib.

Objective To observe the effect of early occupational therapy intervention on unilateral spatial neglect caused by stroke.Methods A total of 92 patients with unilateral spatial neglect caused by stroke were ran- domly divided into a treatment group(46 cases)and a control group(46 cases).The cases of the control group were treated by routine clinical treatment plus positioning on the bed,passive joint motion,bridging movement,facilitation techniques,balance training in sitting and standing positions,gait training immediately after the patients' conditions got stable.The patients in the treatment group were treated with activities of daily living(ADL)training in addition to the interventions employed in the control group.Results Effect of the treatment group are superior to that of the control group as reflected by the scores with Fug1-Meyer scale and Barthel Index(P

OBJECTIVETo establish a method for the determination of 5-hydroxy-7-methoxyflavan in Daemrnonorops draco by HPLC.

METHODDikma Diamonsil C15 column(4. 6 mm x 150 mm, 5 microm) was used. The mobile phase consisted of (60:40). The temperature of column was 30 degrees C. The flow rate was 1:0 mL x min(-1) and the detection wavelength was at 210 nm.

RESULTThe calibration curve was in good linearity with in the range from 0.01 to 0.10 microg (r = 0.9999). The average recovery was 100.1% (n=6).

CONCLUSIONThe method is simple, rapid, as well as precise and reliable, and can be used for the determination of 5-hydroxy-7-methoxyflavan in D. draco.

Objective:To investigate the correlation between collateral flow compensation mode and interventional treatment decision in patients with severe bilateral internal carotid artery stenosis/occlusion.Methods:According to the location of internal carotid artery lesions, patients with severe stenosis/occlusion of bilateral internal carotid artery were selected at the Second Affiliated Hospital, Qiqihar Medical University and the Sixth Medical Center of PLA General Hospital from May 2017 to June 2020.Results:A total of 42 patients were finally enrolled and divided into 4 types, including 34 males and 8 females with median age 61±8(48-82)years. The collateral circulation pathways manifested as following modes: anterior communicating artery collateral, posterior communicating artery collateral, ophthalmic artery collateral, posterior cerebral middle cerebral artery pial anastomosis collateral, posterior choroidal artery anterior choroidal artery collateral, external carotid internal carotid artery C4 segment collateral, pericallosal artery anastomosis collateral, dural and pial collateral and neovascularization. Type Ⅰ severe stenosis/occlusion of C1 segment was found in 20 cases (47.6%). There were 5 cases (11.9%) of type Ⅱ severe stenosis/occlusion from C2 to C6 prior to ophthalmic artery branch. Type Ⅲ severe stenosis/occlusion occurred in 2 cases (4.8%) after the split of ophthalmic artery. Type Ⅳ was mixed type in 15 cases (35.7%).Conclusions:The compensatory pathway of collateral circulation is closely related to the lesion location. To explore the compensatory pattern of collateral circulation is helpful for clinicians to accurately analyze the lesion characteristics and guide individualized interventional therapy.
