AIM: To explore the surgical methods and clinical effects on young patients with congenital lower eyelid entropion.
METHODS: There were 27 patients ( 45 cases ) who suffered congenital lower eyelid entropion accepted the modified blepharosphincterectomy. The clinical effects and complications were evaluated.
RESULTS: After followed up for 6mo, 42 eyes were fully recovered, 3 eyes were unsuccessful and the cure rate was 93%, 5 eyes suffered minor lower eyelid skin folds, none had lower eyelid retraction and ectropion.CONCLUSION: Modified blepharosphincterectomy is an ideal cosmetic surgical treatment for young patients with congenital lower eyelid entropion. It is an effective surgical treatment with fewer complications.

ObjectiveTo explore the value of virtual touch tissue quantification (VTQ) in the evaluation of clinical pathological typing of advanced gastric cancer.MethodsFifty six patients who had been diagnosed as gastric cancer were examined using acoustic radiation force impulse.According to clinical pathological typing,all cases were divided into highly-moderately differentiated adenocarcinoma (14 cases) and non-highly-moderately differentiated adenocarcinoma (42 cases).A comparison with clinical pathologic results was made after surgery.The correlation of VTQ results and clinical pathological typing of gastric cancer was analyzed.ResultsThe VTQ value of highly-moderately differentiated adenocarcinoma was lower than that of non-highly-moderately differentiated adenocarcinoma [(1.49 ± 0.44) m/s vs (2.12 ± 0.45) m/s],with statistical significance( t =-4.53,P <0.05).According to the maximum area under the ROC curve,the cutoff value of VTQ was 1.795 m/s,the sensitivity and specificity were 78% and 86%,respectively,the Youden's index was 0.64,and with high reproducibility(Kappa =0.81).ConclusionsVTQ could initial estimate the clinical pathological typing of advanced gastric cancer before operation.

ObjectiveTo explore the value of virtual touch tissue quantification (VTQ) in evaluating Lauren classification of advanced gastric carcinoma.MethodsForty-one patients with gastric cancer proved by endoscopic biopsy performed preoperative VTQ examination,and the findings were compared with postoperative pathologic results via hematoxylin -eosin and Alcian Blue-Periodic Acid Schiff (AB-PAS) staining.ResultsIn 41 patients,26 cases were diagnosed as diffuse type and 15 cases as intestinal type by pathology after operation.The shear wave velocity(SWV) of diffuse type was higher than that of intestinal type [(1.72± 0.83)m/s vs (1.05± 0.66)m/s,t =2.819,P=0.008] measured by virtual touch tissue quantification (VTQ).According to the area under the ROC curve,the cut- off value of SWV in gastric cancer tissues for assessing the diffuse type was 1.045 m/s with a sensitivity of 80.8% and specificity of 73.3 % respectively.ConclusionsVTQ could be considered as a promising method to distinguish the Lauren classification in patients with advanced gastric carcinoma.

Electronic case report forms (eCRFs) instead of the traditional paper case report forms (pCRFs) are increasingly used by investigators and sponsors of clinical research. We include a total of 14 phase III studies (8 pCRF, 6 eCRF) to compare paper and electronic data documentation both quantitatively and qualitatively in clinical studies. The result suggests that adaptions of electronic data capture (EDC) in clinical trials have the advantages in optimization of data capture process, improvement of data quality and earlier clinical decision compared to paper-based methods. Furthermore, the successful implementation of EDC requires accouplements with corresponding data management processes and reallocation of resources.

Due to a great amount of data in clinical trials, the data cleansing needs to adopt a variety of measures, including the latest developed visual check approach. According to the different types of clinical data and the different stages in the course of clinical data management, this study reviews 8 types of visual graphics that show the relevance and trend among the data. The series of graphics can rapidly detect abnormal data, monitor clinical research in real-time, make the data management process much easier and improve the clinical trial efficiency and data quality.

Objective: To explore the correlation between serum level of high molecular weight adiponectin (HMW-ADPN) and arteriosclerosis. Methods: Clinical data of 87 middle-aged and aged people living in home, who underwent health examinations in Xiangya second hospital from Jan 2011 to Dec 2011, were collected. According to carotid-femoral pulse wave velocity (cf-PWV) = 9 m/s, they were divided into group A (cf-PWV<9 m/s, n=21) and group B (cf-PWV≥9 m/s, n=66). Blood pressure, blood lipid, blood glucose etc. were measured and compared between two groups. Results: Compared with group A, there were significant rise in blood pressure, levels of low density lipoprotein cholesterol, triglyceride and total cholesterol, and significant reduction in levels of high density lipoprotein cholesterol (HDL-C), serum total ADPN and HMW-ADPN in group B, P<0.05 or <0.01. Multiple regression analysis indicated that serum HMW-ADPN (B= - 4.469,P=0.011), total ADPN ((B= - 3.965,P=0.012), HDL-C(B= - 2.077,P=0.015) and systolic blood pressure levels (B= 0.045,P=0.045) were independent predictors of cf-PWV. Conclusion: Serum high molecular weight adiponectin and total adiponectin levels may be protective factors against arteriosclerosis. Its role in predicting occurrence and development of arteriosclerosis is worthy of further study.

Objective To investigate the physical fitness status of stationed on an island and the influence factors of military operational ability in order to take effective intervention measures to cope with the problems encountered by the garrison force.Methods The outdoor environment heat intensity of the island was monitored and evaluated by thermal environment monitors.The physical fitness of thirty-eight soldiers randomly selected was evaluated by measuring VO 2max. Ninety soldiers stationed on this island were selected by random sampling , for whom questionnaires and interviews were designed, involving the influence factors of military operational ability .Results This island was a typical humid-hot environment, with high temperature , high humidity and high radiation .The physical fitness of soldiers declined obviously because of the typical humid-hot environment.The top five working environmental factors were high temperature , humidity, solar radiation, wind and seasonal drying .The top five personal factors were physical fatigue , overtraining, injury, mental fatigue and lack of sleep .Conclusion Considering the obviously decreased physical fitness of soldiers caused by the typical humid-hot environment , how to assess military combat effectiveness and how to determine whether the level of combat effectiveness can meet the actual needs of tropical combat , requires scientific indicators and criteria of evaluation .

The target compounds were prepared from 5-aminobenzimidazolone by two steps reaction, and their AChE inhibitory activities were measured by Ellman method in vitro. The AChE inhibitory activity of compound 4d is the best of them, and its IC50 value is equal to 7.2 μmol·L(-1), which is better than that of rivastigmine; moreover the 4d had no inhibitory activities to BuChE. Therefore, the inhibitory activities of 5-aminobenzimidazolone derivatives to acetylcholinesterase are worth further researching.

OBJECTIVETo investigate the effect of antisense VEGF165 infection on the growth of A375 cells in nude mice.
METHODSA375 cells were injected s.c into the axilla of the nude mouse. After the tumor formed, we cut it into 16 pieces equally, then transplanted into another 15 nude mice. There were three groups: Group PBS, Group Ad-GFP, and Group Ad-aVEGF. Four weeks after interfere, the mice were sacrificed and their tumors were excised for naked eye and histological observation. The VEGF expression was checked with ISH and immunohistochemistry staining. The micro-vessel density (MVD) in tumor mass was counted by VIII factor immunohistochemistry staining.
RESULTSThe visible and palpable nodules had developed at all the injected sites. Tumor growth speed was more slowly in Group Ad-aVEGF than that in other groups. GFP gene could express effectively in tumor mass. Ad-aVEGF infection could suppress the growth of tumors, and there were no obvious side effects. Ad-aVEGF resulted more tissue necrosis, but it had no obvious effect on cell apoptosis. VEGF expression was inhibited significantly in Group Ad-aVEGF, and MVD was decreased accordingly.
CONCLUSIONSAd-aVEGF interfere may be a new method against human malignant melanoma, whose main mechanism is to induce ischemia, but not apoptosis.
