Chemotherapy- induced peripheral neuropathy (CIPN) can be caused by many commonly used chemotherapeutic agents, such as taxanes, vinca alkaloids, platinum drugs, thalidomide,and also by newer agents such as bortezomib. Both animal experiments and clinical studies are being conducted to investigate strategies for preventing CIPN or ameliorating established CIPN without affecting the antitumor efficacy of chemotherapy. Treatments using calcium and magnesium infusions,glutathione,lipoid acid are being evaluated for their clinical application.

Objective To predict the length of peripherally inserted central venous catheters(PICC) with electronic chest radiograph scale measurement techniques, and observe its clinical effect. Methods A total of 185 breast cancer patients from October 2012 to December 2013 who were treated by PICC combined with MST guided by ultrasonic technology were as control group. A total of 192 breast cancer patients from January to November 2014 were as observation group. Control group adopted from the puncture point to right sternoclavicular joints impreaaion nip down again to the third floor of PICC in vitro measurement method. Observation group used to right sternoclavicular joints from the puncture point plus right sternoclavicular joints to subcarinal 1 vertebral body length, right sternoclavicular joints to subcarinal 1 vertebral body length measurement by electronic chest radiograph scale technology directly measured from the electronic chest radiographs.

AIM:To investigate the effect of high glucose on the expression of an endoplasmic reticulum stress marker glucose-regulated protein 78(GRP78),and explore its underlying mechanism.METHODS:(1) Human umbilical vein endothelial cells(HUVECs) were exposed to normal glucose(5.5 mmol/L) and high glucose(30 mmol/L) for 24 h,36 h or 48 h.Cell viability was determined by MTT method.Cell apoptosis was detected by flow cytometry analysis.The expression of proteins was evaluated by Western blotting analysis.RESULTS:After treated with high glucose for 24-48 h,the expression of GRP78 increased early but decreased at 48 h of incubation,while cyclooxygenase-2(COX-2) expression increased in a time-dependent manner.COX-2 selective inhibitor nimesulide inhibited high glucose induced changes of GRP78 expression and also inhibited high glucose induced cell apoptosis.CONCLUSION:Prolonged high glucose exposure changes the expression of GRP78 in a COX-2 dependent manner in HUVECs.

Objective To investigate the relationship between peripheral inflammatory cytokines and anxiety symptoms in patients with the first?episode generalized anxiety disorder. Methods 48 patients diagnosed with the first?episode generalized anxiety disorder according to ICD?10 criteria and 48 healthy sub?jects were recruited. Peripheral levels of IL?1, IL?2, IL?4, IL?5, IL?6, IL?8, IL?10, IL?12p70, GM?CSF and IFN?γ of both groups were evaluated by enzyme?linked immunosorbent assay ( ELISA) ,and CRP was evalua?ted by immunoturbidimetric method. Generalized Anxiety Disorder Scale( GAD?7) and State?Trait Anxiety Inventory ( STAI ) were used to assess the levels of overall anxiety, state anxiety and trait anxiety. Results The levels of CRP ( ( 1. 19 ± 0. 80 ) mg/L vs ( 0. 68 ± 0. 70 ) mg/L, t=3. 31 ) , IL?1α( ( 70. 34 ± 3.60)pg/ml vs (16.94±3.42)pg/ml, t=74.50),IL?2((7.25±3.42)pg/ml vs (4.95±2.31)pg/ml, t=3.85), IL?4((102.02±73.14)pg/ml vs (75.55±32.78)pg/ml, t=2.29),IL?6((12.55±2.37)pg/ml vs (2.71±1.35) pg/ml, t=14.79),IL?8((44.64±16.21)pg/ml vs (35.69±11.70)pg/ml, t=3.10),IL?12((18.16±24.17) pg/ml vs (10.82±4.72)pg/ml, t=2.06),IFN?γ((23.32±15.52)pg/ml vs (16.48±6.80)pg/ml, t=2.79), GM?CSF((19.07±11.12)pg/ml vs (13.40±8.54)pg/ml, t=2.80) in patients with the first?episode general?ized anxiety disorder were significantly higher than normal controls(P<0.05) . Both SAI and TAI had signifi? cantly positive correlation with the levels of IL?1α, IL?2, IL?6, IL?8, IL?12, IFN?γ and GM?CSF ( r=0.24?0.76, P<0.05) . Conclusion The levels of some peripheral inflammatory cytokines in patients with the first?episode generalized anxiety disorder are significantly increased,and they have positive correlation with gener?al anxiety,state anxiety and trait anxiety,which may suggest some immune system defects in the patients.

To investigate the presence of integrated Epstein-Barr virus (EBV) DNA in the NK/T cell lymphoma (NKTCL) ge-nome and analyze the integration information in the genome of NKTCL cell lines. Methods: PCR and in situ hybridization were used to detect EBV infection in five EBV (+) NK/T samples and four EBV (-) NK/T samples provided by the biobanks of the First Affiliated Hospi-tal of Zhengzhou University. Whole-genome DNA of the samples was sequenced and subjected to bioinformatics analysis. Whole-ge-nome sequence alignment was used to identify the EBV integration sequence. BLAST analysis was used to compare EBV fasta files of the samples and EBV fasta library. CREST software was used to extract softclip reads, filter all paired reads, and enumerate their distri-bution on chromosomes. The integrated genomics viewer (IGV) was used to compare the distribution of reads in partial regions of chromosome. PCR was used to amplify the high-frequency integration region of the EBV DNA. The amplified fragments were sanger se-quenced. Results: EBV DNA and EBER expression were detected in five EBV (+) NK/T samples but not in the four EBV (-) NK/T samples. Sequencing depth, coverage depth, proportion of coverage, and proportion of alignment all met the requirements for subsequent re-search. Sequence alignment revealed that the captured sequences were viral sequences. Filtered reads were most numerous in EBV (+) NKTCL cell line SNK, YTS, and EBV (+) nasal NKTCL tissue. The reads were non-randomly enriched in chromosome 2. EBV DNA inte-gration in the 400 bp region of chr2:30234084-30234483 caused insertion or deletion in the chr2p23.1 site. Conclusions: EBV DNA is highly integrated in the chr2p23.1 site of EBV (+) NKTCL cells and may affect the expression of related genes.

Neurexin-3α, discovered in 2016, is a new type of autoimmune encephalitis antibody. Anti-neurexin-3α antibody-associated encephalitis is generally associated with prodromal symptoms or mood changes, having main clinical manifestations as seizures, memory disorders, confusion or loss of consciousness, central ventilation insufficiency, abnormal behavior, and speech disorders. This paper reviews the relevant research progress at home and abroad about pathogenesis, diagnosis and differential diagnosis, treatment and prognosis of anti-neurexin-3α antibody-associated encephalitis, so as to expand the understanding of clinicians for this disease.

Background and objective Afatinib is an irreversible ErbB-family blocker with a clinical activity in non-small cell lung cancer with epidermal growth factor receptor (EGFR) mutations. hTe aim of this study is to assess the safety of afatinib in patients with advanced lung adenocarcinoma. Methods Patients with lung adenocarcinoma (stage IIIb or IV) with EGFR mutations were ifrst-line treated with an oral administration of afatinib (40 mg/d) until disease progression. Adverse events, effects, and survival condition were observed. Results hTe most common adverse events were diarrhea (n=5, 100%), skin rash (n=4, 80%), and mucositis/stomatitis (n=4, 80%). Moderate toxicities not exceeding grade 3 were observed. Relatively, the most serious adverse reaction was mucositis/stomatitis. Mild diarrhea occurred in all patients. hTree patients experienced temporary drug withdrawal and dose reduction because of adverse reaction. Among the four patients who were evaluated, partial response was observed in two patients (50%), one with stable disease (25%) and one with progressive disease (25%). Median progression-free survival was 9.7 months, whereas median overall survival was 18.4 months. Conclusion Afa-tinib was approved as ifrst-line treatment for patients with advanced lung adenocarcinoma. hTe most common adverse events were diarrhea and skin rash. However, mucositis/stomatitis related to afatinib should also be considered. Considering the small number of cases, the conclusion requires more trials for conifrmation.
