Purpose: To observe the efficacy and the side effects of oxaliplatin( OXA) in combination with vinorelbine (VRB) in the treatment of drug resistant non-small-cell lung cancer( NSCLC) . Methodii: Thirty-five patients with drug resistant lung cancer were treated by OXA + VRB. OXA 100 mg/m2, VRB 25 mg/m , on d 1, which were given by bronchial arteries injection, and VRB 25mg/m2 was given by venous injection on d 8. One cycle was given every 3 weeks and total six cycles was given. Results: There was 1 patient who showed completed remission( CR), 14 patients showed partial remission( PR), 13 patients showed stable disease( SD) and 7 patients showed progress disease( PD) after the sixth cycle. The response rate was 42. 9%. The major toxicities were peripheral sensory neuropathy and leukopenia. Conclusions: The regimen of OXA plus VRB is effective on drug resistant and advanced NSCLC and the side effects are tolerable. There is higher response rate and lower neurotoxicity when the medicines are given by arterial injection than by venous injection.

Kruppel-like factor 6 (KLF6) was reported as tumor suppressor in multiple cancers. However, loss of chromosomal locus spanning KLF6 is relatively infrequent in previous published studies. To explore the role of KLF6 in hepatocellular carcinoma (HCC), we examined the gene for expression change, loss of heterozygosity (LOH) and mutation in 26 HCC samples. The expression levels of KLF6 were significantly down-regulated in HCCs, as detected by qRT-PCR. LOH occurred in 11 (52%) of 21 tumors, and all the samples with LOH showed KLF6 down-regulation. The mutational frequency was 24%, and sequence changes located in activation domain of KLF6. Furthermore, MTT assay showed a significant antiproliferative effect of the wt KLF6 transfected in HepG2 hepatoblastoma cells. Fluorescence-activated cell sorting analysis revealed that KLF6 could induce apoptosis. These findings indicate that deregulation of KLF6, together with genetic abnormalities of allelic imbalance and mutations, may play a role in HCC pathogenesis.

Objective To analyze the phenotypes of lymphocytes in cerebrospinal fluid derived from the patients with neurosyphilis. Methods Samples of cerebrospinal fluid from 12 patients with neurosyphilis and 20 patients with latent syphilis were collected and analyzed by flow cytometry for CD4 and CD25 expression. Results There was a significant increase in the number of white blood cells in the cerebrospinal fluid of patients with neurosyphilis. FACS analysis showed that most leukocytes were lymphocytes predominated with CD4 + T cells in neurosyphilis patients which were almost 4 times more than that in latent syphilis. However, there was a significant decrease in the proportion of CD4+ CD25high regulatory T cells (Tr) in neurosyphilis patients compared with that in latent syphilis patients. Conclusion A dramatic increase in CD4+ T cell frequency suggested its pathogenic role in neurosyphilis, whereas a decrease in CD25high Tr frequency indicated that CD4 + CD25high Tr cells might play an important role in immune homeostasis of central nervous system.

Objective To investigate the expression and genetic alterations of KLF6 in hepatocellular carcinoma (HCC) and explore their functional mechanisms in the oncogenesis and development of HCC. Methods Real-time quantitative-PCR, direct sequencing and LOH approaches were used to detect KLF6 genetic abnormalities in HCC. The experiment had 2 groups, an experimental group and a control group. In the experimental group, the transfected plasmid pcDNA3.0 was recombined with KLF6 and tranfected into HCC HepG2 cells. MTT, flow cytometry and Western blotting were used to observe the effect of anti-oncogene wild type KLF6 on HepG2 cells by transgenic method for 48 h.Results Expression levels of KLF6 were significantly downregulated in HCCs(P＜0. 01), as detected by qRT-PCR. LOH occurred in 11 (52%) of the 21 tumors, and all the samples with LOH showed KLF6 down-regulation. The mutational frequency was 29%, and sequence changes located in activation domain of KLF6. Meanwhile, MTT assay showed a significant antiproliferative effect of the transfected wtKLF6 on HepG2 cells(42.7%, P＜0.05). Fluorescence-activated cell sorting analysis revealed that KLF6 induced apoptosis. Conclusion The deregulation of KLF6 together with genetic abnormalities of allelic imbalance and mutations may play an important role in HCC pathogenesis.

Objective To evaluate the efficacy of selective laser trabeculoplasty (SLT) as treatments of secondary glaucoma after intravitreal silicone oil injection. Methods Forty-five cases(45 eyes) of silicone oil glaucoma (SOG) from June 2014 to April 2016 were enrolled and divided into two groups according random digits table. The SLT treatment group had 21 cases (21 eyes), and drug treatment group had 23 cases(23 eyes).Intraocular pressure(IOP)changes were recorded 1 d, 1 week, 3 weeks, 1 month, 2 months, 3 months,4 months,5 months and 6 months after treatment.Results The decrease of IOP in SLT group was (11.47 ± 2.23), (11.27 ± 2.59), (10.43 ± 2.55), (11.93 ± 2.71), (13.75 ± 2.57),(13.93 ± 2.65),(10.45 ± 2.53)and(12.73 ±2.86)mmHg(1 mmHg=0.133 kPa).IOP of the control group decreased respectively (7.53 ± 3.29), (9.57 ± 3.49), (8.78 ± 4.21), (8.74 ± 3.86), (6.12 ± 4.41),(7.84 ± 3.26),(8.84 ± 4.25),(8.24 ± 3.56)mmHg.There was significant difference between the two groups 1 week, 1 month, 2 months, 3 months,4 months,5 months and 6 months after treatment (t = 4.17, 1.38, 2.89, 6.32, 3.89, 5.32, 5.19, P < 0.05 or < 0.01). Conclusions SLT is a safe and effective option for the treatment of patients with SOG.
