Objective To investigate the indications and surgical approaches of full-thickness eyelid reconstruction with superficial temporal artery island flap and oral mucosa free grafting,and evaluate the safety and efficacy.Methods A total of 13 eyes of 13 patients with wide full-thickness eyelid defect were treated by the eyelid reconstruction with superficial temporal artery island flap and oral mucosa free grafting.The defect area was(33.67?8.35) mm?(16.44?4.45) mm and the size of island flap was(38.56?8.99)mm?(18.44?4.00)mm.Eight cases were treated with oral lip mucosa grafting,while the other 5 with hard plate muco-periosteal free grafting.Follow up was conducted for 6 to 24 months. Results The flaps were clinically viable in 10 cases and partially viable in 2.One was inviable for venous circumfluence failure,and a successful free skin grafting was conducted 3 months postoperation.All the grafted oral mucosa survived.Five cases underwent the second surgery to thin the island flap,among whom 3 were performed eyelid suspension with the frontal muscle.The survived flaps were similar to skin in colour,soft in nature,and could effectively protect the eyeballs. Conclusion The superficial temporal artery island flap along with oral mucosa free grafting works well in wide full-thickness eyelid reconstruction.

While the medicine pattern of biomedicine turn to biological-psychology-society, the medical trouble communication becomes more and more important in the medical service. Good medical trouble communication ability is the essential condition of doctor. As oral cavity clinicians, only by gasping the principle of communication can we appropriately utilize some skills of communication exchange,establish the good medical trouble relations with the patient and achieve the good treatment result finally.

Retinal vein occlusion (RVO) is a common clinical disease causing vision loss. Risk factors such as diabetes, atherosclerosis are closely associated with RVO. Xuesaitong injection is used extensively in clinical treatment of RVO, however the mechanism is still unclear. In this study, we investigated the protective effect of Xuesaitong injection on RVO rat model. Using a compound-target network of Xuesaitong on anti-RVO constructed by literature mining, we aim to elucidate the multi-compound, multi-target effect of Xuesaitong injection. Fifteen potential targets of Xuesaitong injection associated with inflammation, angiogenesis, apoptosis, and coagulation were identified in this study. VEGF, IL-1beta and IL-6, three important targets in the compound-target network were further experimentally validated. This study provided experimental evidence for Xuesaitong injection being effective in treating RVO and a network view on its anti-RVO mode of action through a multi-compound and multiple-target mechanism.

Toxicogenomics (TGx) refers to a set of technologies that assess genome-wide responses after toxic agent exposure. Altered gene expression patterns that are caused by specific exposures reveal how toxicants may disrupt cellular processes and lead to side effects. Development and application of " omics" technology facilitate the toxicogenomic research which sharing and interpretation of the enormous amount of biological information generated in toxicologic field. In recent years TGx has been widely valued and successfully applied as an effective research tool to evaluate the toxic effects of traditional Chinese medicine (TCM). Here we reviewed current progress in the field of TGx and focused on its application in traditional Chinese medicine safety evaluation, especially in revealing the mechanism, finding potential toxic biomarkers and studying compatibility detoxification of TCM.

OBJECTIVE: To analyze the latency of posture evoked response of normal lower limb muscle in different stimulations and explore its influencing factors. METHODS: The normal lower limb was induced to produce postural evoked response by the dynamic posturography through two kinds of perturbations, the supporting surface rotation stimulation (Toes-up and Toes-down) and the horizontal perturbation stimulation (Forward and Backward). The latencies of tibialis anterior muscle and gastrocnemius muscle were recorded by surface electromyography acquisition system. The differences of the left and right limb, gender and height on the latency of postural evoked response were analyzed. RESULTS: (1) Under the Toes-up and Backward perturbation, the latency of tibialis anterior muscle was longer than gastrocnemius muscle; under the Toes-down and Forward perturbation, the latency of gastrocnemius muscle was longer than tibialis anterior muscle. (2) The latencies of left limb and right limb had no significant difference. (3) The latency in male was longer than that in female. (4) The latency gradually increased with the increase of height. CONCLUSION In the postural evoked response, different perturbations, gender and height have significant impacts on the latency of posture evoked response of lower limb muscle. However, the effect of height and gender should be not considered referring to the same individual.

Background Currently,the recommendation when treating acute biliary or pancreatic disease during pregnancy is to perform endoscopic retrograde cholangiopancreatography (ERCP) without radiation exposure,either empirically (with no radiographic guidance) or with ultrasound guidance.However,few published studies compared these two ways.This study aimed to compare ultrasound-guided ERCP with the procedure without radiographic guidance in the treatment of acute pancreaticobiliary disease in pregnant patients.Methods The clinical data of 68 pregnant patients with acute pancreaticobiliary disease admitted to our hospital between January 2004 and May 2010 were reviewed retrospectively.ERCP was performed without radiographic guidance in 36 cases (group A) and with ultrasound guidance in 32 cases (group B).Data on the following variables were compared between the two groups:surgical success rate,rate of complete stone removal,time to resolution of clinical manifestations and laboratory indicators,length of hospital stay,complications,outcome and differences in efficacy of ERCP during different stages of pregnancy.Results In group A,the rates of surgical success and complete removal of stones were 69％ and 60％,respectively; the corresponding values were 91％ and 89％ in group B (P ＜0.05).Postoperatively,clinical manifestations improved rapidly in all patients; there was no statistically significant difference between the groups (P ＞0.05).Leukocyte counts and liver function had improved significantly after one week in all patients; they recovered more quickly in group B ((8.64±1.83)days vs.(14.57±3.74) days,(14.29±4.64) days vs.(20.00±5.40) days,P ＜0.01).The hospital stay was shorter in group B ((16.28±7.25) days vs.(28.00±6.83) days,P＜0.001).The complication rate was 14％ in group A and 3％ in group B (P ＜0.05).There were no significant differences between the two groups in the procedure's efficacy during different stages of pregnancy.Conclusions In the treatment of acute pancreaticobiliary disease during pregnancy,ultrasound-guided ERCP is safer and more effective than performing the procedure empirically without radiographic guidance when performed by experienced practitioners.Its more widespread use is recommended.

0.05), CGI and HAMA.

OBJECTIVETo evaluate the diagnostic value of bone marrow (BM) involvement detected by F-18-fluorodeoxyglucose-positron emission tomography/computed tomography ((18)F-FDG PET/CT) in patients with newly diagnosed diffuse large B-cell lymphoma (DLBCL).

METHODSThe study population comprised 81 consecutive patients with newly diagnosed DLBCL. All patients had both (18)F-FDG PET/CT and standard BM biopsy at iliac crest. In 9 patients, additional direct BM biopsy at FDG-avid bone lesion was performed.

RESULTSAmong all 81 cases, 23 were diagnosed as BM involvement by PET/CT. Of the 23 positive cases 17 were confirmed by biopsy. However, only 11 cases were diagnosed by merely bilateral iliac crest biopsy. In patients in early stage of disease (18)F-FDG PET/CT had the same results as bilateral iliac crest biopsy.

CONCLUSION(18)F-FDG PET/CT is superior to standard BM biopsy in detecting BM involvement in newly diagnosed DLBCL patients. In patients with FDG-avid bone lesions, direct PET/CT-guided bone biopsy seems to be more accurate than standard BM biopsy.
