Many college students’ English is not good enough to meet the need of the society. Pairing general English with ESP is proposed so as to solve the problem. Taking college English teaching in schools of traditional Chinese medicine as a case, this paper analyzes the key factors such as teaching materials, language teachers, students, teaching objectives, methods and environment in the teaching process in order to prove that pairing general English with ESP is feasible.

Objective To investigate the role of GST-? mRNA in the development and pathogenesis of esophageal cancer. Methods Twenty two matched pairs of esophageal cancerous and noncancerous tissues were obtained from 22 patients with esophageal cancer in an endemic region. AP-PCR was used for determining the differential gene fragments and RT-PCR for detecting the expression of GST-? mRNA. Results Differential random amplified fragments were found in 6 cancerous tissues, and none of the noncancerous tissues. The 5T differential gene fragments were of 1.0 kb, and by cloning, sequencing, and sequence homology analysis, no homologous sequence was found in the gene library. The expression rates of GST-? mRNA in cancerous and noncancerous tissues were 54.5%(12/22) and 18.2%(4/22), respectively. Conclusions Whether the 5T differential gene fragment is a new gene candidate or is a marker of oncogene remains to be further studied. The expression of GST-? mRNA in esophageal cancerous tissue was markedly enhanced.

The survival ability of electro medical equipment under complex electromagnetic environment is researched and then various kinds of electromagnetic pulse threats of medical equipment are discussed.At last,the strategies on strengthening medical equipment electromagnetic protection capability are studied form the transfer ways of electromagnetic pollution.

OBJECTIVE To investigation central venous catheter-related infections(CRI) in critical patients. METHODS Fifty-nine cases from Jul 2006 to Jun 2007 in intensive care unit (ICU) of our hospital were analysed retrospectively. RESULTS Among 59 cases, 27 cases were with positive results of fungi (51.85%) and bacteria(48.15%) in which G+(25.93%) and G-(22.22%). CONCLUSIONS CRI is related to the indwelling time, fungi are the major pathogens. It is important to prevent CRI through careful nursing. We must pull out the catheters if recessary and antibiotics should be used reasonablly.

5cm hepatic cancer, the effective rate (CR+PR) was 60 8% (62/102), no change (NC) rate 39 2% (40/102), and the 1-, 2-, 3-year survival rates 67 6% (69/102), 49 1% (50/102) and 39 2% (40/102), respectively. The effective rates (CR+PR) in patients with bone tumor and lung cancer were 100%(12/12) and 60%(3/5), respectively. There were no other severe complications found. Conclusions Ultrasound-guided microwave intervention is a safe, effective and feasible method for hepatic cancer, lung cancer and bone tumor.

Objective: To study the apoptosis and the expression of proliferating cell nuclear antigen (PCNA) in colorec-tal neoplasms and their relationship with neoplasm biological behavior. Methods: Apoptotic index (AI) and proliferative index (PI) were determined in paraffin-embedded tissues from 62 cases of colorectal carcinomas, 15 cases of colon adenomas and 10 cases of normal colon mucosa with immunohistochemistry S-P method and TUNEL technique. Results: The difference of PI and AI was significant in normal colon mucosa, colon adenomas and colorectal carcinomas (P

Objective To investigate the protective effect of Quercetin on kidneys in diabetic rats. Methods STZ induced diabetic rats were given quercetin 100 mg?kg -1 ?d -1 for 8 weeks. Urinary albumin excretion rate (UAER) was measured by radioimmunoassay. The changes of creatinine clearance rate (Ccr) and glomerular protein kinase C (PKC) activities were determined. The expression of TGF ? 1 mRNA of renal cortex in diabetic rats were determined by RT PCR analysis. The glomerular changes were also observed morphologically. Results In untreated diabetic rats, Ccr, UAER, kidney weight/body weight and PKC activity in renal glomeruli were significantly increased, the expression of TGF ? 1 mRNA in renal cortex was elevated, and glomerular hypertrophy existed. After Quercetin treatment, Ccr, UAER, PKC activity and the expression of TGF ? 1 mRNA were markedly reduced as compared with those of untreated diabetic rats in 2 and 8 weeks, no significantly abnormal changes in kidney morphology were observed in Quercetin treated group. Conclusion Quercetin ameliorates early diabetic renal hyperdynamic abnormality via inhibiting PKC activity, in which inhibiting of TGF ? 1 production seems to be involved. Reduction of the PKC activity is important in preventing or delaying the development of diabetic nephropathy.

AIM: To investigate the effect of yigu capsule drug-containing serum on proliferation, ALP activity and expression of interleukin-11 mRNA in Sprague-Dawley rat osteobalsts in the co-culture system. METHODS: (1) Osteoblasts and osteoclasts were isolated from 1 and 5-day-old Sprague-Dawley rats, respectively. The osteoblasts-osteoclasts co-culture system was built to prevent the two kinds of cells from contact and allow the media to exchange. The experiment included two groups, drug-containing sera group and control group. (2) The osteoblasts proliferation, ALP activity and expression of interleukin-11 mRNA were detected by the MTT, 4-aminoantipyrine spectrometric methods and FQ-PCR,respectively. RESULTS: In drug-containing sera group, the osteoblasts proliferation, ALP activity, expression of IL-11 mRNA were higher than those of control group (P

AIM:To observe the effect of TNF-? and Yigu capsule drug-containing sera on osteoblasts apoptosis in osteoblasts-osteoclasts coculture system.METHODS:(1)Twenty female Sprague-Dawley rats,10 months old,were randomly assigned into 2 groups,NS and Yigu capsule groups,to prepare blank sera and drug-containing sera.(2)The DNA gel electrophoresis method was used to detect apoptosis of osteoblasts treated with different concentration of TNF-? in order to determine the best dosage in the co-culture system.(3)The cells were divided into four groups,TNF-? group,normal group,TNF-? + blank serum group and TNF-? + drug-containing serum group.DNA gel electrophoresis,acridine orange staining and flow cytometry were used to observe osteoblast apoptosis in these groups.RESULTS:(1)After induced by TNF-? for 72 h at a concentration of 60 ?g/L,relatively typical DNA ladder appeared in TNF-? group.(2)Only two DNA brands appeared and most of cells were well-proportioned stained in TNF-? + drug-containing serum group,the rate of osteoblasts apoptosis in TNF-? + drug-containing serum group(9.60%?0.26%)was obviously lower than that in the TNF-? group(26.90%?0.06%)and TNF-? + blank serum group(18.10%?0.06%).CONCLUSION:TNF-? induces osteoblast apoptosis in the co-culture system,and Yigu capsule drug-containing serum prevents osteoblast apoptosis induced by TNF-?.
