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.

OBJECTIVETo discuss whether asiaticosides could effectively reduce the endothelial cell damage as a biochemical modulator, so as to further inhibit the post-stenting intima-media membrane hyperplasia.
METHODHuman aortic smooth muscle cells and aortic fibroblasts were selected and divided into the blank group, the rapamycin group and the asiaticoside group and the rapamycin and asiaticoside group. The expressions of muscle cells and fibroblasts TGF-beta1, Smad7 and I-collagen gene were determined by RT-PCR. The expression quantity of I-collagen protein was assayed by ELISA. The coefficient of drug interaction (CDI) between rapamycin and asiaticoside was calculated. Additionally, 16 Chinese mini-swines were randomly divided into group A and group B. One sirolimus drug-eluting stent of the same type was implanted after the high-pressure pre-expansion of anterior descending artery balloon. After the operation, the group A was intravenously injected with normal saline 30 mL x d(-1). Whereas the group B was intravenously injected with asiaticoside 30 mg x kg(-1) x d(-1)(diluted to 30 mL). The expressions of plasma vWF of the two groups were measured at the 7th and 14th days after the operation. At the 28th day after the operation, tissues of the stented vessel segments were sliced and stained to calculate the vessel area, inner stent area, lumen area and neointima area
RESULTCompared with the control group, the combination group showed significant up-regulation in smooth muscle cells and fibroblast Smad7 gene, down-regulation in TGF-beta, and obvious inhibition of I-collagen gene expression (P < 0.01). As for smooth muscle cells, there was no difference in the expression of I-collagen between the combination group and the rapamycin group, with CDI at 0. 83. As for fibroblasts, there was a significant difference in the expression of I-collagen between the combination group and the rapamycin group (P < 0.05), with CDI at 0.77. Plasma vWF of the group B was significantly lower than that of the group A (P < 0.05) at the 7th and 14th days after the operation. At the 28th day after the operation, no difference was observed in vessel area and stent area between the two groups. However, the lumen area in the group B was significantly larger than that of the group A(P < 0.05), and the neointima area of the group B was significantly smaller than that of the group A (P < 0.05).
CONCLUSIONAs an effective biochemical modulator for rapamycin, asiaticosides could inhibit TGF-beta expression, significantly decrease the synthesis and secretion of extracellular matrix, further inhibit the post-stenting intima-media membrane hyperplasia and reduce the endothelial cell damage by effectively up-regulate the expression of Smad7 protein.

Objective To summarize experiences of serious perioperative complications management of obstructive sleep apnea hypopnea syndrome (OSAHS) , and evaluate the effect of intervention in decreasing the incidence of serious complications. Methods Retrospective analysis of clinical data in Shenyang General Hospital of PLA and Liaoning Province Jinqiu Hospital of OSAHS surgery cases from January 1995 to December 2009 were included in this study, patients were divided into two groups according to with or without intervention. Experience and lessons were analyzed. Results Patients without and with intervention were 402 and 521 respectively, and uvulopalatopharyngoplasty (UPPP) cases in each group were 387 and 390. Five patients in the first group who accepted UPPP had breathing difficulty and were all successfully rescued, while no one in the second group had breathing difficulty. The difference was significant (P<0. 05). Sixteen patients in the first group had severe bleeding after UPPP, while only 5 patients had the severe bleeding in the second group. The difference was significant, too P <0. 05. No breathing difficulty cases in the second group, and serious bleeding cases in each group was 5 and in 1, there was no significant difference (P > 0. 05 ). Conclusions Breath difficulty and serious bleeding are serious perioperative complications of OSAHS surgery, and with systemic intervention the incidence of the complications can be decreased.

The study was aimed to investigate the influence of penicillin and streptomycin on proliferation, apoptosis and extracellular secretion (ECS) produced from human umbilical cord derived mesenchymal stem cells (MSC). MSC were isolated from umbilical cord tissue, then the immunotyping, multipotent differentiation and proliferation of these cells were assayed by cytometry, cytochemistry and MTT respectively. The expressions of ECS and apoptosis-related genes (bcl-2, bax) were detected by quantitative RT-PCR. The results showed that the phenotype of these cells matched with the characteristics of MSC. Penicillin and streptomycin of low concentrations promoted MSC proliferation, with the most effective concentration of 100 U/ml. Expressions of ECS cultured in addition of penicillin and streptomycin were down-regulated. Furthermore, apoptosis-related factor (bcl-2/bax) expression levels in low concentrations penicillin and streptomycin groups were higher than that in the control group. It is concluded that low concentrations penicillin and streptomycin can promote the proliferation and reduce the apoptotic rate, but high dose can inhibit the ECS component expression of MSC.
