BACKGROUND:Bmi-1 (B-cel-specific moloney murineleukemia virus insertion site), a colorectal cancer stem cellgene is of great significance in the regulation of telomere reverse transcriptase activity and transcriptional status as wel as cellaging and carcinogenesis.
OBJECTIVE:To investigate the correlation between Bmi-1 expression and clinicopathological changes of colorectal cancer.
METHODS:The expression of Bmi-1 mRNA in carcinoma cells was detected in 50 cases of colorectal cancer using quantitative real-time PCR. The expression of Bmi-1 protein in cancer tissue was detected by hematoxylin-eosin staining and immunohistochemical staining SP method.
RESULTS AND CONCLUSION:Sex, age, and tumor size showed no different effects on the expression of Bmi-1 mRNA. The expression of Bmi-1 protein showed no significant difference in patients who were different in sex, age, tumor size and Duke staging of tumor. The expressions of Bmi-1 mRNA and protein in patients with lymph node metastasis and depth of invasion deeper than the serosa were much higher than those in patients with no lymph node metastasis and depth of invasion shal ower than the serosa (P<0.05). The expression of Bmi-1 mRNA was much higher in patients with higher Duke staging cancer (P<0.05). The expression of Bmi-1 mRNA and protein are closely related to different pathological features of colorectal cancer, such as metastasis, infiltration, and Duke staging.

Objective: To evaluate the safety and efficacy of domestic intravenous doxycycline in the treatment of urinary tract infections.Methods:A multicenter,double-blind,randomized controlled clinical trial of intravenous doxycycline and azithromycin on patients with urinary tract infections were conducted.The dosage of doxycycline was 0.2g,once daily,for 5~12d and that of azithromycin was 0.5g,once daily,for 5~12d.Both drugs were given intravenously.Results: In this trial,62 patients were enrolled in doxycycline group,and 60 were enrolled in azithromycin group.The overall efficacy rates and cure rate in trial and control group were 100%,90.32% and 73.33%,95% respectively.There was statistical significant difference in the cure rates between the two groups.The bacterial clearance rates in two groups were 92.5% and 88.9% respectively.The adverse drug reaction rates were7.9% and6.7% respectively.There were no statistical significant differences in the above results between the two groups.The activity of doxycycline against gram-positive organisms was generally higher than that of the other 5 antibacterial agents.Antibacterial activity of doxycycline against gram-negtive bacterium was similar to or stronger than the other antibacterial agents.Conclusion: The results suggest that domestic doxycycline injection with powerful antibacterial activity and wide spectrum is highly effective in treating urinary tract infections.

Objective:To evaluate the safety and efficacy of domestic cefepime in the treatment of lower-respiratory tract bacterial infections.Methods:A double-blind,randomized control clinical trial of intravenous cefepime on patients with lower-respiratory tract bacterial infections were conducted.The regimen of the two groups were 2g,twice daily for 7 to14ds.Both drugs were given intravenously.Results:In this trial,30 patients were enrolled in trial group and other 30 patients were enrolled in control group.The overall efficacy rates and cure rate in trial and control group were 93.33%?63.33% and 96.67%?70% respectively.The bacterial clearance rates were 96% and 100% respectively,and the adverse drug reaction rates were 3.3% and 0%. There was no statistical significant differences in the above results between the two groups.The activity of cefepime against gram-positive organisms was generally higher than that of the other 4 antibacterial agents.Conclusion:The results suggested that demostic cefepime with powerful antibacterial activity and wide spectrum has the same safety and efficacy as imported one in treating lower-respiratory tract bacterial infections.

Objective:To evaluate the safety and efficacy of domestic intravenous gatifloxacin in the treatment of respiratory tract infections.Methods:A multicenter,double-blind,randomized controlled clinical trials of intravenous gatifloxacin and levofloxacin on patients with respiratory tract infections were conducted.The regimen of the two groups were 0.2g,twice daily,7～14days.Both drugs were given intravenously.Results:In this trial,40 patients were enrolled in gatifloxacin group,39 patients were enrolled in levofloxacin group.The overall efficacy rates and cure rate in trial and control group were 95%,65% and 94.87%,64.1% respectively.The bacterial clearance rates were 86.8% and 81.1% respectively in two groups.The adverse drug reaction rates were 7.5% and 10.2% in trial and control group respectively.There were no statistically significant differences in the above results between the two groups.The activity of gatifloxacin against gram-positive organisms was generally higher than that of the other 4 antibacterial agents.Antibacterial activity of gatifloxacin against gram-negtive bacterium was similar or stronger than the other antibacterial agents.Conclusion:The results suggest that domestic gatifloxacin injection with powerful antibacterial activity and wide spectrum is a highly effective and safe broad-spectrum new quinolone in treating respiratory tract infections.

Objective To compare the effect of extracapsular cataract extraction and phacoemulsification. Methods Three hundred and twenty-six cases (360 eyes) of senile cataract were divided into two groups by random digits table with 163 cases (180 eyes) in each. One group underwent phacoemulsification (phacoemulsification group),and the other group underwent extracapsular cataract extraction with small incision(no-phacoemulsifieation group). A comparison was carried out between the two groups of the vision and complications after operation. Results In phacoemulsification group,7 d after operation 18.33%(33/180)had 0.4 or less in vision,66.11%( 119/180) were 0.5-0.9,15.56%(28/180) were 1.0 or better. In no-phacoemulsification group,7 d after operation, 18.89% (34/180) were 0.4 or less in vision,66.67% (120/180) were 0.5-0.9,14.44% (26/180) were 1.0 or better. During operation,posterior capsular ruptured and vitreous prolapsed in 4.44% (8/180) in phacoemulsification group and 3.33%(6/180) in no-phacoemulsification group. Corneal edema:there were 16.11%(29/180) in phacoemulsification group and 17.22%(31/180) in no-phacoemulsification group. The curative effect between the two kinds of operation mentioned above was almost the same and had no significant difference (P ＞0.05). Conclusion The no-phacoemulsification is simple and economical, wihch is suitable for basic hospitals.

Iron metabolism is involved in cancer initiation, progression, metastasis, and angiogenesis.Ferritin,ferritin receptor,transferrin, and transferrin receptor are often overexpressed in cancers. Not only iron deprivation can inhibit the growth of cancers,but also may suppress matrix metalloproteinases-related metastasis.

The conventional approach of systemic viral gene delivery is often associated with limited therapeutic efficacy and toxicity because of a lack of tumor specificity. Mesenchymal stem cells have the tumortracking abilities which provide possibility that the stable and high level of anti- cancer gene expression could be acquired within local tumor and a novel approach for better tumor-targeted gene delivery.

The citations of original foreign language books in doctorial dissertations of Suzhou University in 2013 were analyzed,which showed that the number of cited original foreign language books on humanities and social sciences was greater than that on other science, the cited books were not limited to those that were recently published, the number of cited original foreign language books published by university press was greater than that published by other publishers. Suggestions were put forward for improving the acquisition of original foreign language books.

Subjective visual perceptions experienced by patients during cataract surgery under local anesthesia have been given more and more attention now.Intraoperative visual experiences,including non-light perception,light perception,one or more color sensation,flash,movement,instrument,hands or fingers of surgeon etc.,are complained in parts of patients.These sensations and experience often lead to a fear of patient.Being aware of these intraoperative sensations of fear from patient is necessary for us to take the preventing strategy in advance.In addition,counseling of these patients prior to surgery may alleviate fears and improve the satisfaction of patient with surgery outcome.This paper reviewed the current studies on this phenomenon,discussed its clinical implications and possible mechanism,and suggested novel approaches to reduce its negative impact on the surgery.
