Objective To evaluate the efficacy of recombinant human interferon α-2b gel onflooding prevention in loop electrosurgical excision procedure (LEEP) during and after the operation.Method The 152 patients with cervical disease were randomly divided into three groups: group A(recombinant human interferon α-2b gel treatment group), group B (hypophysin treatment group)and groupC(control group). Results The amount of intraoperative bleeding and the amount of post-operative bleedingof the group A was (2.57±1.19) ml and (2.24±1.75) ml, the group B was (3.00±1.49) ml and (45.86±26.14) hal, the group C was (45.62±39.57) ml and (56.90±41.90) ml, respectively. There was no differencebetween group A and group B in the amount of intraoperative bleeding (P>0.05), but significantly less thangroup C (P<0.01). There was no difference between group B and group C in the amount of post-operativebleeding (P>0.05), but significantly much more than group A (P<0.01). Conclusion Recombinanthuman interferon α-2b gel is effective on reducing intraoperative and post-operative bleeding in LEEP.

Objective To investigate the retrieval mechanism of prospective memory,spatiotemporal patterns of event-related potentials (ERP) were used to reveal neural correlates of the prospective interference effect. Methods A task of matching two sequential patterns was taken as the ongoing task and the detection of patterns with two salient levels as prospective memory tasks. Experiments were performed in blocks for single ongoing task block and two prospective memory blocks. Results No significant behavioral effect was found for prospective interference [reaction time(ms):control blocks 750.29±161.33,high salience blocks 770.94±174.89,low salience bocks 764.79±174.12,F(1.52,25.82)=0.48,P =0.57 and correction rate(%):control blocks 85.89±8.07,high salience blocks 88.26±7.00,low salience blocks 87.91±7.28,F(1.50,25.57)=2.46,P =0.12].But significant ERP effect was found at bilateral frontal regions from 160 ms to 240 ms for both two prospective memory blocks. Moreover,greater negativity at the right frontal polar region appeared significantly at 360'440 ms for higher salient patterns. Conclusion Prospective memory is retrieved based on strategic monitoring and high salient stimuli may enhance to keep the prospective goal and improve task switching.

Objective To establish a HPLC method for the determination of baicalin and berberine hydrochloride in Com-pound Qinbo Granules. Methods The gradient elution was performed on a Diamonsil C18 column using method-water (0. 05 % phosphate acid and 0. 1% trithylamine) as mobile phase, and the detection wavelength was 276 nm. Results The linear calibration curve of baicalin was obtained in the range of 10. 08～201.6 mg·L-1 with an average recovery of 98. 1% (RSD=1.11%). The linear calibration curve of berberine hydrochloride was in the range of 4. 08～81.6 mg·L-1 with an average re-covery of 97.9 % (RSD=1.24 %). Conclusion The method is simple and reproducible. It can be used for the quality con-trol of Compound Qinbo Granules.

Pharmacogenetics and pharmacogenomics are promising fields that will enable personalized therapy. However, one of the most important issues to be conquered in the practice of personalized medicine is the translation of scientific discoveries into better therapeutic outcomes. The international pharmacogenetic and pharmacogenomic approaches made in the field of personalized medicine and drug discovery are summarized in this review.

Objective To observe the levels of intercellar adhesion molecule-1(ICAM-1)of rat intestinal mucosa microvascular endothelial cells in sepsis rat,and to investigate the possible protective effect of adrenomedullin on the expression of intercellar adhesion molecule-1(ICAM-1)of rat intestinal mucosa microvascular endothelial cells,and to confirm whether adrenomedullin can decrease released inflammatory factors to slow down or inhibit the occurrence and development of sepsis.Methods The rat intestinal mucosa microvascular endothelial cells were isolated and cultured in vitro,and it was divided into sham operated(sham operated serum),sepsis serum(with addition of sepsis serum)and ADM serum(with 0.lng/kg adrenomedullin 6h after sepsis treatment)groups.The soluble ICAM-1(sICAM-1)content in RIMMVECs culture supernatant was measured by ELISA at the 24th hour after serum stimulation.Results The ICAM-1 content in the supernatant of sepsis group [(0.33 ±0.04)ng/L] was obviously higher than that in sham operated [(0.15 ± 0.02)ng/L] and ADM [(0.17 ± 0.04)ng/L] group(P ＜ 0.05),but ADM group was no significantly different compared with sham operated group(P ＞ 0.05).Conclusions ADM could decrease the expression of ICAM-I in RIMMVECs,and the low level of ICAM-1 could suppress its downstream inflammation factors and inhibit the occurrence and development of sepsis.

Research in lymph node imaging has made great progress in recent years. With the increasing in-depth researches and clinical applications of MRI, PET and molecular imaging, the sensitivity, specificity and accuracy of detecting lymph node metastases have also been improved. Incorporating techniques such as various pulse sequences, contrast enhancement and lymph-node contrast agents has made MRI a superior method for detecting lymph node metastasis of breast cancer in clinical settings.

Identification of the cellular targets of bioactive compounds is a major challenge and a key issue in chemical biology and drug discovery. As an important technology in functional proteomics, small molecule probes play a pivotal role in the identification of cellular targets of bioactive compounds. This review is intended to introduce the application principles and structural design philosophy of chemical probes for the purpose of mechanistic study. Recent cases of successful application were also discussed to further demonstrate the principles and significance ofbioactive small molecule-based probes.

Objective To compare the risk effects of different antiplatelet therapies on gastrointestinal injury and summarize the endoscopic characteristics of gastrointestinal mucosal injury in the elderly. Methods The dyspepsia symptoms, gastrointestinal bleeding and endoscopic findings were retrospectively evaluated among 577 patients who received the antiplatelet therapy with aspirin and/or clopidogrel. Results The risk of dyspepsia symptoms and gastrointestinal bleeding was slightly higher in clopidogrel group than in aspirin group (both P＞0.05, x2=0.48, 0.72), and OR (95% CI): 1.10 (0.59-2.07) and 1.74 (0.48-6.33), for the risk of dyspepsia symptoms and gastrointestinal bleeding, respectively. In aspirin plus clopidogrel group, the risk of dyspepsia symptoms had no significant increase as compared with aspirin or clopidogrel group (x2=0.37, 0.03, for aspirin or clopidogrel group, respectively, both P＞0.05), but the risk of gastrointestinal bleeding was significantly higher than in aspirin group (x2=5.43, P＜0.05), OR (95% CI): 4.77 (1.15-19.79) and slightly higher than in clopidogrel group (P＞0.05). In this study, 57 patients received endoscopy and the detection rate of erosion or ulcer was 78.9%. Erosion (61.4%) was most in the gastric antrum; gastric ulcer (10.6%) located in gastric antrum and angle; duodenal ulcer (18.0%) located in bulb. In patients with dyspepsia symptoms erosion (70.5%), were most likely found but patients with gastrointestinal bleeding showed mainly ulcer (69.2%). Conclusions In the elderly the use of clopidogrel alone is not safer than low-dose aspirin and the combination would increase the risk of gastrointestinal bleeding. The detection rate of erosion or ulcer is high in patients with symptoms. Patients with dyspepsia symptoms most likely show erosion, but patients with gastrointestinal bleeding have mainly ulcer and complex ulcers more common.

Patients with long-standing history of ulcerative colitis have an increased risk of developing colitis-associated colorectal cancer.The risk factors include longer duration of colitis,greater anatomic extent of colitis,degree of inflammation of the bowel,family history of colorectal callcer,the presence of primary sclerosing cholangitis.etc.The two kinds of molecular pathogenesis that contribute to colon carcinogenesis are chromosomal instability and microsatellite instability.In order to reduce cancer morbidity,colonescopic surveillance and chemoprevention should be carried out in patients with ulcerative colitis especially in those high risk patients.New endoscopic techniques increase the sensitivity and shed a new light on tumor surveillance.
