Language,as a cartier of specified social culture,is closely and complementarily associated with it.Considering the especial education targets of medical universities and colleges,the present curriculum and the trend of international communication,College English is obliged to focus on humanistic value and necessarily plays its constructive role in heightening students' humanistic quality.

Papillary thyroid cancer (PTC) is the most common type in thyroid carcinomas.Recently,the prevalence and diagnostic rate of PTC has got significantly high with the general use of ultrasound.Nowadays,more and more studies have suggested that the coexistence of PTC and diabetes is common.They indicated that hyperglycemia would induce the deterioration of oxidative stress injury,chronic inflammation,insulin resistance,obesity,dyslipidemia,deficiency of vitamin D and dysimmunity.All of these may break the balance of oxidation and antioxidation and result in disordering signal pathway,accumulation of inflammatory cytokines,over activating of insulin and insulin-like growth factor-1,changing the metabolic pathways,which will promote the occurrence and progression of PTC.

Traditional Chinese medicine (TCM), an important component of complementary and alternative medicine, has evolved over thousands of years with its own unique system of theories, diagnostics and therapies. TCM has been increasingly used in the last decades and become well known for its significant role in preventing and treating cancer. We believe that TCM possesses advantages over Western medicine in specific aspects at a certain stage of cancer treatment. Here we summarize the advantages of TCM from three aspects: preventing tumorigenesis; attenuating toxicity and enhancing the treatment effect; and reducing tumor recurrence and metastasis.

Objective To preliminarily investigate the conditions of the performance of chlorine dioxide generator for drinking water disinfection and know the overall situation of the industry.Methods From 2007 to 2008,6 companies'products were chosen for this investigation according to certain rules,and their performance indicators,such as chlorine dioxide output and conversion rate were tested by using the Five-step iodimetry method.Results On-site generating technology was commonly used,and the average conversion rate of the compound type generator was 57.06%,and the pure type generator was 84.78%.Conclusion The conversion rate of the pure type generator is better than the compound type,and the newly invented pure type generator has much better performance and lower disinfection cost.

Aim To investigate the reversal of resistance to doxorubicin by CJZ3,a lomerizine derivative,in doxorubicin-resistant human myelogenous leukemia(K562/DOX)cells.Methods The effect of CJZ3 on P-glycoprotein(P-gp)function and resistance to doxorubicin in K562/DOX cells were observed by using flow cytometry and MTT assay.Results CJZ3 increased intracellular uptake and accumulation of rhodamine123(Rh123)in K562/DOX cells in a concentration-related manner,significantly inhibited the efflux of Rh123 from the cells,and increased the doxorubicin-induced cytotoxicity,apoptosis rate,Caspase-3 activity in doxorubicin-treated cells and the intracellular accumulation of doxorubicin.Conclusions The reversed effect of CJZ3 on resistance to doxorubicin in K562/DOX cells was associated with its inhibitory effect on P-gp function in vitro.

OBJECTIVETo explore the mechanism of natural moxibustion on regulating immune imbalance in asthma rats.

METHODSSeventy SD male rats were divided into a normal group, a placebo group, a dexamethasone group, a big-cake for long-course moxibustion group, a big-cake for short-course moxibustion group, a small-cake for long-course moxibustion group and a small-cake for short-course moxibustion group, ten rats in each one. The rat model of asthma was established by egg albumen sensitization and stimulation in all the groups except the normal group. The natural moxibustion was used in all moxibustion groups, in which big cake of 1 cmX 1 cm size was used in the big-cake groups and small cake of 0.5 cmX 0. 5 cm size was used in the small cake groups. According to relevant acupoints, the natural moxibustion was performed, 5 h per time, once a day. Four times of treatment was considered one course, and three courses were required in the long-course groups and one course was required in the short-course groups. Intraperitoneal injection of dexamethasone was applied in the dexamethasone group, which had the same course as long-course moxibustion group. After the treatment, changes of EOS in peripheral blood of asthma rats were observed; enzyme linked immunosorbent assay (ELISA) was applied to test the contents of IgE, IL-4 and IFN-gamma in the lung tissue; real-time Q-PCR method was adopted to measure the expression level of transcription factor T-bet and GATA binding protein 3 (GATA-3) in the lung tissue.

RESULTSCompared with the normal group, the EOS in whole blood as well as IL-4 and IgE in plasma were all increased in the placebo group (all P< 0. 01), IFN-gamma in plasma was obviously decreased (P<0. 01); while the levels of EOS, IgE and IL-4 were significantly reduced (all P<0. 01), the content of IFN-gamma was increased (P<0. 01) in all moxibustion groups and dexametnasone group. Compared with the normal group, the expression of T-bet mRNA in the placebo group was significantly reduced (P<0. 01). Each treatment group could significantly increase the expression of T-bet mRNA and reduce that of GATA-3 mRNA (P<0. 01). Compared with the short-course moxibustion groups, the expression of T-bet mRNA was obviously increased in the long-course moxibustion group and dexamethasone group (both P<0.01), and that of GATA-3 mRNA was reduced (P<0.01). There was no significant difference between long-course moxibustion group and dexamethasone group (P> 0. 05), and also no significant difference could be seen between big-cake moxibustion group and small-cake moxibustion group (P>0. 05).

CONCLUSIONThe natural moxibustion could obviously reduce airway inflammation in asthma rats. With time passing, the efficacy is enhanced, indicating evident timeliness, which has no apparent relationship with the size of moxibustion cake.

Objective To observe the changes of neutrophil gelatinase associated lipocalin,NGAL after endoplasmic reticulum stress by thapsigargin in renal tubular epithelial cells.Methods The renal tubular epithelial cells were treated with thapsigargin to establish the model of endoplasmic reticulum stress (ER group).CHOP and GRP78 expression were detected by Western-blot to confirm endoplasmic reticulum stress in renal tubular epithelial cells by thapsigargin.NGAL expression were detected by Western-blot in ER group and control group(normal renal tubular epithelial cells).Results After treated with 2.5 μmol/L and 5 μmol/L thapsigargin for 4 hours and 8 hours respectively,endoplasmic reticulum stress in the renal tubular epithelial cells were significantly increased comparing with control group (0.585 ± 0.045 to 0.523 ± 0.030;0.785 ± 0.049 to 0.728 ± 0.064),which was approved by the increased expression of CHOP and GRP78 (P ＜ 0.05).The expression of NGAL was significantly increased in ER group (0.567 ± 0.024 to 0.826 ± 0.057,P ＜ 0.05) and it was corresponded with the changes of CHOP and GRP78,which increased significantly with the severity of endoplasmic reticulum stress.Conclusion Endoplasmic reticulum stress can be induced by thapsigargin in renal tubular epithelial cells.The expression of CHOP,GRP78 and NGAL were significantly increased correspondingly with the severity of endoplasmic reticulum stress.It is speculated that the expression of NGAL may be related with endoplasmic reticulum stress in tubular epithelial cells.
