In the past, panretinal photocoagulation (PRP) and vitrectomy (PPV) were the main treatments for proliferative diabetic retinopathy (PDR). In recent years, anti-vascular endothelial growth factor (VEGF) drugs have been used more and more widely in PDR due to their advantages in rapidly subtracting new blood vessels, reducing leakage, and promoting the absorption of blood. The combination of anti-VEGF drugs and PRP in the treatment of PDR, especially high-risk PDR, can increase the rate of neovascularization and prevent some patients with mild to moderate vitreous hemorrhage from PPV. The application of anti-VEGF drugs during the perioperative period of PPV can also reduce bleeding during the operation, shorten the operation time, and reduce surgical complications. Although clinical studies have confirmed that anti-VEGF drugs can be used as an alternative treatment for PRP, most patients require multiple and long-term treatments, which increase the psychological and economic burden of patients. It is expected that the cost of anti-VEGF drugs and the development of long-acting dosage forms can be reduced and bring better efficacy and benefits to PDR patients in the future.

Objective To evaluate the efficacy of dexmedetomidine injected into axillary sheath in alleviating the tourniquet pain during brachial plexus block with ropivacaine.Methods Sixty ASA physical status Ⅰ or Ⅱ patients,aged 18-60 yr,weighing 52-85 kg,scheduled for the replantation of amputated finger,were randomly divided into 2 equal groups (n =30 each):ropivacaine group (group R) and dexmedetomidine mixed with ropivacaine group (group DR).All patients underwent axillary brachial plexus block guided by a nerve stimulator.When the intensity of electric stimulation ≤ 0.4 mA,flexion of fingers or wrist still existed,and the local anesthetic was injected into the axillary sheath.0.5％ ropivacaine 40ml was injected in group R.0.5％ ropivacaine mixed with 100μg dexmedetomidine 40ml was injected in group DR.The pressure of inflation was set at 200-250mmHg,and the stress duration was 120 min.Tourniquet pain and the level that the patients could tolerate was evaluated using visual analog scale (VAS) at 120 min of stress status.The patient' s satisfaction with anesthesia was rated and the development of adverse cadiovascular events and local and systemic adverse reactions were recorded.Excessive sedation was measured with Ramsay score in group DR.Results Compared with group R,the tourniquet pain that the patients could tolerate was significantly increased,the severity of tourniquet pain was reduced and the incidence of adverse cadiovascular events was decreased in group DR (P ＜ 0.01).No serious tourniquet-related complications were observed in both groups.No patients developed excessive sedation in group DR.Conclusion Dexmedetomidine 100μg injected into the axillary sheath can safely and effectively alleviate the tourniquet pain when used during brachial plexus block with ropivacaine.

Objective:Entrepreneurial failure refers to the process of entrepreneurial performance continuous decline until the business is bankrupt. The aim of this research is to analyze implicit stigma effect against entrepre-neurial failure in college students. Methods:Sixty-four college students in a natural class participated in this survey, 4 D values of the total tool of entrepreneurial failure implicit stigma and its three dimensions (including cognitive appraisal,emotional reaction,and behavior tendency)were assessed with the traditional implicit association test (IAT). Through independent sample t test,the differences between zero and 4 D values were analyzed. The differ-ences of four D values at gender and entrepreneurial experienceon were explored,the difference between reaction time of the compatibility task and incompatibility task was analyzed,and the reliability of the tool of implicit stigma effect against entrepreneurial failure was evaluated. Results:The 4 D values were all greater than zero. In 3 inde-pendent dimensions and total IATs,the automatic association between entrepreneurial failure and negative words was closer relative to positive words (P<0. 001 ),it showed that their implicit negative attitude against entrepre-neurial failure was significant. Split-halfreliability and internal consistency coefficient of the total tool of entrepre-neurial failure implicit stigma were respectively 0. 87 and 0. 82. Conclusion:In this study,the entrepreneurial failure implicit stigma effect may be significant in college students. These college studeuts have implicit negative cognition and emotion,and discrimination behavior tendency against entrepreneurial failure.

Purpose To study the clinicopathological features and immunohistochemical characteristics of IgG4-related disease. Meth-ods The microscopic characteristics and immunohistochemical staining (EnVision) of IgG, IgG4, CD138 and CD34 have been per-formed on 12 cases of IgG4-related disease. Results IgG4-related disease were characterized by diffuse fibrosis, accompanied with in-filtrating of dense lymphocytes and plasma cells surrounding neurovascular and occlusive phlebitis. Immunohistochemical staining re-sults showed the ratio of IgG4+/IgG+ cells were over 40%. Conclusions IgG4-related disease is absent of characteristic clinical and radiographic features and is easily misdiagnosed as tumor. Preoperative serum IgG4 detection could be used as the prior examina-tion for the suspected cases.

BACKGROUND:Nowadays, the component content of assisted reproductive culture medium and their test methods are unclear in the quality standards. We need to establish the test methods to fil this vacancy, so as to control the quality of assisted reproductive culture medium effectively. OBJECTIVE:To establish an evaluation method for determination of fructose and glucose in assisted reproductive culture medium, thereby based on which to establish the quality standards. METHODS:High performance liquid chromatography-differential refractive index detector was adopted and Rezex RCM-Monosaccharide Ca2+(8%) (300.0 mm×7.8 mm) column was used. The mobile phase was ultrapure water at the flow rate of 0.6 mL/min and the temperature of 80 ℃. RESULTS AND CONCLUSION:Resolution of the peaks of glucose and fructose was 3.2. The linear ranges of glucose and fructose were 30.1-502 mg/L (r=0.999 8) and 102-408 mg/L (r=0.999 8), respectively. The relative standard deviation of reproducibility test was 0.17%and 0.40%, respectively. The relative standard deviation of stability test was 0.22%and 0.73%, respectively. The glucose group and fructose group average recovery rates were 1.22%and 1.38%, respectively. The methodology of High performance liquid chromatography-differential refractive index detector accorded with the requirements.
