UNLABELLED: AbstractObjective: To explore the distribution characteristics and clinical significance of peripheral blood monocyte subgroups in patients with diffuse large Bcell lymphoma(DLBCL). METHODS: The percentage of peripheral blood monocyte subsets of 82 DLBCL patients (including 32 newly diagnosis, 29 remission and 21 relapse) and 30 healthy controls were detected by flow cytometry, and the correlation with the clinical characteristics and its diagnostic value of DLBCL were analyzed. RESULTS: The proportion of intermediate monocytes in patients with newly diagnosed DLBCL group was higher than that in healthy controls (t=5.888, P<0.01). The proportion in relapsed group was higher than those in newly diagnosed DLBCL group（t=2.106，P=0.04） and remission group （t=6.882， P＜0.01）, and the proportion of intermediate monocytes in newly diagnosed DLBCL group was higher than that in Remission group (t=3.969, P<0.01). With the increase of International Prognostic Index (IPI) score, the percentage of intermediate monocytes in patients with DLBCL increased (r=0.37). Furthermore, when the proportion of intermediate monocytes was 10.91% as the cutoff value, the sensitivity and specificity of the whole sample were 90.60% and 9100%, respectively. CONCLUSION The disease progression is related to the increased intermediate monocytes, which can be used as a potential diagnostic index for DLBCL.

Gastric cancer is the second most common cancer in China. Alcohol consumption is related to gastric cancer as a sig-nificant risk factor. Some key enzymes is expected to influence the alcohol-associated metabolism. There are many molecular mechanisms of alcohol-related gastric cancer, such as generation of acetaldehyde by microbiome, inflammation, up-regulation of Pol Ⅲ genes, carcinogen-DNA adduct formation and genetic polymorphisms of alcohol metabolizing enzymes. Different types and concentrations of alcohol have different effects on the devel-opment of gastric cancer. This review presents a systematic ex-position on the molecular mechanism of alcohol-associated gastric cancer.

Long non-coding RNA(lncRNA)is a class of RNAs with a number of nucleotides greater than 200,no specific open reading frame and no protein coding. LncRNA could have a sig-nificant influence on the regulation of gene expression during cell growth,and also play a potential role in the development,pro-gression and resistance of tumors. Consequently,it becomes a new tumor research hot spot after miRNA. Many studies have shown that aberrant expression of lncRNA may lead to anti-tumor drug resistance. Furthermore,this resistance is not only derived from individual differences in patients,but also from genetic and epigenetic differences in the tumor. In this paper,we summarize the recent advances in lncRNAs associated with drug resistance that may help overcome drug resistance,so as to improve and develop new therapeutic strategies.

Objective To evaluate the ergotropic effect of bone cement on pedicle screw fixation in treatment of osteopo-rotic thoracolumbar fracture.Methods Fifty-three patients with osteoporotic thoracolumbar fracture, admitted from Jun. 2013 to Dec. 2014, were included for treatment by augmentation of pedicle screw fixation with bone cement. All patients underwent pre-operative examination of bone mineral density with T-score ≤-2.5 and augmentation of pedicle screw fixation with injection of 1.5 ml bone cement in adjacent to fractured vertebra. All patients were treated with anti-osteoporosis therapy pre- and post-operation, ob-served and recorded with basic conditions and complications. At pre-operation, one-week post-operation and last follow-up, pain vi-sual analogue scale (VAS) and neurological function score (ASIA) of all patients were recorded, and the compression rats of anterior and posterior edge of fractured vertebra, and compression rats of spinal canal and Cobb angel of all patients were measured.Results All the 53 patients were successfully undergone operation in about 90-140 min with blood loss of about 150-350 ml. No spinal cord or nerve injury, dural tear and obvious leakage of bone cement and screw loosening occurred during operation. All patients were followed up for 12 to 36 months and the neurological function obviously recovered contrasted with pre-operation. X-ray and CT examination at last follow-up showed good fractures healing, good position and non-loosening of internal fixation device and non-leakage of bone cement. At one week post-operation and last follow-up, VAS, compression rats of anterior edge and posterior edge of fractured vertebra, compression rats of spinal canal and Cobb angel were significantly lower than those at pre-operation (P<0.05), but no significant differences existed on these parameters between 1 week post-operation and last follow-up (P>0.05).Conclusions Augmentation of pedicle screw fixation with bone cement can effectively strengthen the initial stability of pedicle screw in osteo-porosis, restore the height of fractured vertebra and reduce the compression of spinal canal, which will help the correction of spinal kyphosis and neurological function recovery. This method can well maintain long-term stability of internal fixation in osteoporosis and height of fractured vertebra, and significantly reduce the risks of long-term screw loosening and vertebral collapse.

Objective To investigate the expression of the excision re-pair cross complementing 2( ERCC2) and P53 in the tissue of advanced liver cancer, and the relationship between the expression and the scheme with platinum chemotherapy curative effect and prognosis.Methods A total of 56 cancer patients were given oxaliplatin 135 mg? m-2 and cisp-latin 75 mg? m-2 for treatment of 2-4 recycle.Use the immunohisto-chemistry to detect the expression of the ERCC2 and P53 in the tissue of advanced liver cancer, give a platinum-based drugs chemotherapy, and then evaluate the chemotherapeutic effect, progression -free survival time and overall survival time.Results The expression of ERCC2 and P53 was associated with curative effect of platinum chemotherapy (P<0.05).The overall survival time of patients with positive expression of ERCC2 and P53 was longer than that of patients with the negative expression ( P<0.05 ) , and the progression-free survival time of patients with P53 positives was extended ( P <0.05 ) .Conclusion The expression of the ERCC2 and P53 was associated with the curative effect of platinum chemo-therapy in the gastric carcinoma patients, which can be used as a detection index to evaluate the prognosis of the gastric cancer by chemotherapy.

Appropriate selection and measurement of lead biomarkers of exposure are critically important for health care management purposes, public health decision making, and primary prevention synthesis. Lead is one of the neurotoxicants that seems to be involved in the etiology of psychologies. Biomarkers are generally classified into three groups: biomarkers of exposure, effect, and susceptibility.The main body compartments that store lead are the blood, soft tissues, and bone; the half-life of lead in these tissues is measured in weeks for blood, months for soft tissues, and years for bone. Within the brain, lead-induced damage in the prefrontal cerebral cortex, hippocampus, and cerebellum can lead to a variety of neurological disorders, such as brain damage, mental retardation, behavioral problems, nerve damage, and possibly Alzheimer's disease, Parkinsons disease, and schizophrenia. This paper presents an overview of biomarkers of lead exposure and discusses the neurotoxic effects of lead with regard to children and adults.

OBJECTIVETo evaluate levels of lead (Pb) and cadmium (Cd) in the breast milk in the second postpartum month, to investigate the relationship between Pb/Cd levels in breast milk and some sociodemographic parameters, and to explore whether these levels affect the infants' physical status or the mothers' psychological status (postpartum depression).

METHODSA cross-sectional study was conducted between November 2009 and December 2010. Altogether 170 healthy mothers were enrolled from Nanjing Maternity and Child Health Care Hospital. The inclusion criteria were: voluntary to participate in this study, healthy, with no chronic disease, breastfeeding in the second postpartum month, living in a suburban but not non-industrial area of Nanjing, and not occupationally exposed to toxic metals. All the mothers completed a questionnaire and were evaluated based on the Edinburgh Postpartum Depression Scale (EPDS) to identify the risk of postpartum depression. Pb and Cd levels in breast milk were determined by inductively coupled plasma mass spectroscopy. The infants of these mothers were examined for their z scores of weight for age, length for age, head circumference for age, and body mass index for age.

RESULTSThe median breast milk levels of Pb and Cd were 40.6 μg/L and 0.67 μg/L, respectively. In 164 (96.5%) of the 170 samples, Pb levels were higher than the limit reported by the World Health Organization (> 5 μg/L). Breast milk Cd level was > 1 μg/L in 54 (31.8%) mothers. The mothers with a history of anemia had a higher breast milk Pb level than those without a history of anemia (41.1 μg/L vs. 37.9 μg/L, P = 0.050). The median breast milk Cd level in those who were active and passive smokers during pregnancy was significantly higher than that in non-smokers (0.88 μg/L vs. 0.00 μg/L, P = 0.025). The breast milk Cd level in the mothers not taking iron and vitamin supplements for 2 months postpartum was higher than in those taking the supplements (iron supplement: 0.74 μg/L vs. 0.00 μg/L, P = 0.025; vitamin supplement: 0.78 μg/L vs. 0.00 μg/L, P = 0.005). Breast milk Cd level at the second postpartum month was negatively correlated with the z scores of head circumference (r = - 0.248, P = 0.042) and weight for age at birth (r =- 0.241, P = 0.024) in girls. No correlation was found between the breast milk Pb/Cd levels and the EPDS scores.

CONCLUSIONConsidering the high levels of Pb and Cd in breast milk in this study, breast milk monitoring programs are necessary.
