Objective: To evaluate the efficacy and safety of chemotherapy alone or combined with multitargeted antiangiogenic TKI (tyrosine kinase inhibitor) for patients with advanced NSCLC (non-small cell lung cancer). Methods: A computer-based online search was performed by using EMBASE, Cochrane Library, PubMed, CNKI (China National Knowledge Infrastructure), Wanfang and VIP databases and Chinese Biomedical Literature Database. Studies of RCT (randomized controlled trial) in accordance with the inclusion and exclusion criteria were included. Quality of the studies was assessed using Jadad score. Data were extracted from the studies by 2 independent reviewers. The Meta-analysis was performed by Stata 12.0 software. Results: Nine RCTs (totally 5 286 patients) were eligible. Meta-analysis showed that there was significant improvement in ORR (objective response rate) [OR (odds ratio): 1.51, 95% CI (confidence interval): 1.21-1.87, P = 0.000] and PFS (progression-free survival) [HR (hazard ratio): 0.83, 95% CI: 0.77-0.88, P = 0.000) in multitargeted antiangiogenic TKI plus chemotherapy group, as compared with chemotherapy along group. Though the pooled HR (HR = 0.94, 95% CI: 0.87-1.01, P = 0.081) for OS (overall survival) showed no significant difference between the two groups. However, there were higher rates of diarrhea (OR: 2.09, 95% CI: 1.48-2.96, P = 0.000), rash (OR: 2.30, 95% CI: 1.59-3.29, P = 0.000), hypertension (OR: 3.30, 95% CI: 2.69-4.06, P = 0.000), hemorrhage (OR: 1.49, 95% CI: 1.07-2.06, P = 0.018), anorexia (OR: 1.45, P = 1.01-2.07, P = 0.042), stomatitis (OR: 2.13, 95% CI: 1.29-3.52, P = 0.003) and hand-foot skin reaction (OR: 4.55, 95% CI: 1.77-11.71, P = 0.002). Conclusion: In comparison with chemotherapy alone, multitargeted antiangiogenic TKI plus chemotherapy had better therapeutic effects on NSCLC. Meanwhile, it also increases the rates of adverse effects such as diarrhea, rash, hypertension, hemorrhage, anorexia, stomatitis and hand-foot skin reaction, which should be prevented and symptomatically treated.

Clinical data of one patient diagnosed as IgG4-related retroperitoneal fibrosis was analyzed.IgG4 and retroperitoneal fibrosis were used as the key words to search literatures from PubMed and Wanfang Database.Clinical data of 27 cases with IgG4 retroperitoneal fibrosis,including clinical manifestation,diagnostic basis,therapeutic method and prognosis,which were retrieved through literatures,were analyzed.A 82-year-old male patient presented with urinary tract obstruction and renal insufficiency.Imaging examination revealed a retroperitoneal irregular lump shadow,and showed chronic inflammation of soft tissues in posterior peritoneum with fibrosis by biopsy pathology.The IgG4-positive plasmocyte infiltration was found by immunohistochemical method.The serum level of IgG4 was significantly increased,which was in accord with IgG4-related retroperitoneal fibrosis.After treatment with methylprednisolone,retroperitoneal lump shadow was obviously dissipated.The serum level of IgG4 became normal.27 cases with IgG4-related retroperitoneal fibrosis were searched through literature retrieval,with 19 confirmed cases,3 suspected cases,and 5 suspicious cases.Male accounted for 92.6％ (25/27),and the average age was 67.6 years old.The cases with the involvement of extraperitoneal organs accounted for 37.0％ (10/27).The misdiagnosis rate was 55.6％ (15/27).23 cases took effective therapy with glucocorticoids.IgG4-related retroperitoneal fibrosis is an orphan disease,which can be misdiagnosed easily.The diagnosis is made with histopathological examination and determination on the serum level of IgG4.The therapy with glucocorticoids is effective.

A molecularly imprinted polymer (MIP) for the selective solid phase extraction of imidacloprid, imidaclothiz, thiacloprid was synthesized by polymerization for 24 h using thiacloprid as template. Dynamic adsorption and selective adsorption test showed that the MIP could quickly adsorb the imidacloprid, imidaclothiz, thiacloprid, with good selectivity for targets. The maximum static adsorption capacity of MIP was 31. 7, 36. 7 and 45. 3 mg / g, respectively. A molecularly imprinted solid phase extraction (MIP-SPE) was developed to separate, clean up and enrich the thiacloprid, imidacloprid and imidaclothiz residue in paddy water, soil, rice, tomato, cucumber. The average recoveries were 80. 2% -98. 8% , with relative standard deviation of 1. 4% -4. 5% . The MIP-SPE was used to analyses the real samples, the result was satisfied.

Objective To investigate the correlation between the expression of EG-1 in breast cancer and the clinicopathological factors and prognosis of breast cancer.Methods EG-1 mRNA expression in 72 malignant and 18 benign breast tissues were evaluated by RT-PCR method,and its correlation with clinical characteristics and prognosis were retrospectively analyzed.Results EG-1 expression level was higher in malignant tissue than in the corresponding benign breast tissue(71%vs.24%,P＜0.05).EG-1 expression was significantly correlated with lymph node metastasis and protein VEGF (P＜0.05)and was not significantly with age,menopause,tnmor size,grade,hormone status,protein Her2 and pS3.The metastastic rate and recurrence rate in EG-1 positive patients was higher than that in EG-1 negative patients.Multivariate Cox model showed that EG-1 positive was an independent factor affecting overall survival and disease free survival.Conclusions EG-1 expression was up-regulated in breast cancer and significantly correlated with lymph node metastasis and protein VEGF.
