Polychlorinated biphenyls(PCBs) is one of persistent organic pollutants which are widely exist in environment.This review described PCBs characteristics and toxicity on animals and human livers.Before now,it was identified that PCBs caused liver damage and hepatocarcinogenicity for animals.However,occupational studies and long-term,low level exposure studies to human beings have found no direct correlation between PCBs exposure and liver damage and carcinogenicity,only accidental environmental exposures have found increased mortality of liver disease.But high morbidity of human liver cancer and detected PCBs in the environment were reported in some regions.It is evident that more researches should be done.

Objective To explore the relationship between postoperative cancer-related fatigue and nutritional risk in patients with colorectal cancer. Method Using convenience sampling method, 159 postoperative colorectal cancer patients were interviewed with cancer-related fatigue scale and PG-SGA 7 days after operation. Results The average score of CRF was (21.28 ± 6.06). The score by PG-SGA was (15.18 ± 5.55). About 94.34%patients were in need of nutritional intervention. The postoperative cancer-related fatigue was positively related to PG-SGA scores(all P<0.05). Conclusions The postoperative colorectal cancer patients are at a high risk of malnutrition, with nutrition risk positively related with somatic cancer-related fatigue. The clinical nursing staff should pay attention to the nutritional status of patients and correct their malnutrition so as to reduce the symptoms of cancer-related fatigue.

ObjectiveTo observe the effects of ultrafiltration extract from Angelica Sinensis Radix and Hedysari Radix on PC12 cell apoptosis induced by H2O2; To discuss its mechanism of action.Methods H2O2 was used in the incubation of PC12 cells to establish the oxidative damage nerve cell apoptosis model. The experiment was divided into normal control group, model group, and three different dosages (0.375, 0.75, 1.5 g/L) of ultra-filtration extracted from Angelica Sinensis Radix and Hedysari Radix after modeling for interference. Rate of cell apoptosis was detected by flow cytometry; mitochondrial membrane potential was measured by laser scanning confocal microscopy; the protein expressions of cleaved Caspase-3, Bax and Bcl-2 were detected by Western blot.Results Compared with the model group, rates of cell apoptosis in the different dosage groups decreased significantly; membrane potential of mitochondria increased; the protein expressions of cleaved Caspase-3 and Bax decreased; the expression of Bcl-2 increased; the ratio of Bcl-2 and Bax increased (P<0.05).Conclusion The ultra-filtration extracted from Angelica Sinensis Radix and Hedysari Radix can inhibit PC12 cell apoptosis induced by H2O2.

Objective To study the prevention and treatment effect of ω-3 fatty acids on intestinal mucosa in critical illness. Methods Forty patients including severe trauma, infection shock were enrolled as experimental group, while 30 healthy people as control group. At the same time, the patients in expermental group were randomly divided into group A and group B(20 cases each). While the patients were. Treated with low calorie parenteral nutrition totally, those in group A received ω-3 fatty acids additionally. The plasma concentrations of dimnine oxidase (DAO), endotoxin were detected by spectrophotography, and TNF-α was detected by ELISA. Results After treatment the concentration of DAO, endotoxin, TNF-α in group A and that of endotoxin in group B decreased significantly (P<0.05 ). While there was no significant difference of endotoxin levels between group A and group B. After therapy, DAO and TNF-α levels in group A were sig-nificantly lower than those in group B (P<0.05 ). The concentrations of DAO and TNF-α in group B were also significantly higher than those in control group (P<0.05). Conclusion ω-3 fatty acids can prevent and treat critical intestinal mucosa effectively.

OBJECTIVE:To discuss the drug resistance situation and influential factors of sputum culture positive tuberculosis patients in a specialized subject hospital. METHODS:The information of sputum culture positive tuberculosis inpatients were col-lected from Heze infectious disease hospital during Jan. 1st 2014 to Apr. 30th 2015;the results of drug sensitive test were analyzed retrospectively by using absolute concentration method. RESULTS:Among 259 patients,137 cases were drug-resistant(52.90%), among including 69(26.64%) mono-drug resistant cases,52(20.08%) poly-drug resistant cases,15(5.79%)multi-drug resistant cases and 1(0.39%)extensively drug resistant case;streptomycin (31.66%) and amikacin (15.44%) were drugs with the highest drug-resistant rate;there was no statistical significance in resistant rate between different genders and ages(P>0.05),the rate of drug resistance in first-treatment patients was 47.21%,and that of the re-treatment patients was 70.97%,the difference was statisti-cal significant(P<0.05). In addition to ethambutol and kanamycin,other all had mono-drug resistance,there were 27 combinations of poly-drug resistance and 9 combinations of multi-drug resistance. Logistic regression analysis showed that treatment history was a risk factor for drug-resistance,the risk of re-treatment patient was 2.734 times of first-treatment patients. CONCLUSIONS:Sputum culture positive tuberculosis inpatients patients have high drug resistance and complex spectrum in the hospital;we should pay great attention to the risk of drug resistance in senile patients and re-treatment patients,and rational use of streptomycin,amikacin,isoni-azid and capreomycin.

Objective To analyze the survey results of iodine nutritional level among women of childbearing age,pregnant,lactating women and infants before and after the adjustment of iodine concentration in salt of Zibo City,in order to provide a scientific basis for reasonable iodine supplement.Methods The iodine content in the residents' edible salt samples was determined in 2011 and 2015.Four groups of target populations including women of childbearing age,pregnant,lactating women and infants from 7 districts and towns of Zibo were investigated to test their urinary iodine level in 2011 and 2015.The monitoring results of the two years were compared and analyzed.Results A total of 2 100 and 2 160 residents edible salt were monitored in 2011 and 2015,and the median of salt iodine were 30.2 and 22.7 mg/kg,there was statistically significant difference in the constitute of salt iodine level between the two years (x2 =141.90,P < 0.01).A total of 354,402,403,362 urine samples of women of childbearing age,pregnant,lactating women and infants' were detected and the median urinary iodine were 161.80,127.20,138.80,147.10 μg/L in 2011,and 350,706,350 and 352 of the corresponding target population's urine samples were detected and the median urinary iodine were 127.80,129.95,70.20 and 152.35 μg/L in 2015.Conclusions The salt iodine median has reduced and the urinary iodine in childbearing age women and infant is in the appropriate level,while it is insufficient in the pregnant women and lactating women after the adjustment of iodized salt concentration in Zibo.It is necessary to promote health education and instruct pregnant women and lactating women to supplement iodine,additionally,surveillance of the iodine nutrition status of the targeted populations should be strengthened.
