International Eye Science 2017;17(10):1849-1851
Internal limiting membrane ( ILM) peeling is commonly used in the operation of idiopathic macular hole ( IMH ) surgery. The success of ILM peeling has been greatly improved with the assistance of vital dyes. Currently, several kinds of vital dyes such as indocyanine green ( ICG ) , brilliant blue G ( BBG ) are applied in the ILM staining. However, all of the vital dyes have potential toxicity and side effects on the retina. In recent years, many kinds of dyes and staining improved emerge in endlessly. This paper reports the progress in the application of different colorants in the operation of IMH.

Objective: To review the problems existing in the development and application of current electroacupuncture (EA) apparatuses, and provide reference for the development of EA apparatuses. Methods: Related literatures about EA apparatus were derived from China National Knowledge Infrastructure (CNKI), Wanfang Academic Journal Full-text Database (Wanfang) and Chongqing VIP Database (CQVIP) between 2013 and 2017. Literatures about the development of EA apparatuses and the application for experimental research and clinical treatment published in Chinese journals were retrieved, and the development and application of EA apparatuses were summarized. Results: Among the 107 selected literatures, 48 types of EA apparatuses were used, of which only 11 models could be found in the registration list and within the validity period. There was no registration information for the EA apparatus newly developed in the past 5 years. The EA parameters used in experimental research and clinical treatment in Chinese medicine were different, and the combination of stimulation parameters was diverse. Conclusion: At present, most of the new EA products are still in the experimental or research stage, and the transformation of results has not yet been achieved. Moreover, there is no unified standard for the use of EA apparatus and its stimulation parameters in experimental research and clinical treatment, which is not conducive to the standardization process of EA stimulation.

Measuring the content of soluble reducing sugar, total sugar, soluble protein, guanosine, alkaloids, and succinic acid of Pinellia ternata tuber were measured by anthrone-sulfuric acid colorimetric method, Coomassie brilliant blue method, RP-HPLC, reverse potentiometric titration, acid dye colorimetry, respectively. The result showed that yellow light could promote the growth and development of P. ternata and increase the content of soluble reducing sugar, total sugar, alkaloids, and succinic acid. Under blue light could promote the content of soluble protein and guanosine. Red and yellow light increased the content of chlorophyll a and chlorophyll b, contrastively blue light reduced the content of chlorophyll a and chlorophyll b. White film through the most uniform spectrum was most conducive to the synthesis of chlorophyll a. As single film, blue film, yellow film were more conducive to the synthesis of chlorophyll a, green film and red film had been relatively beneficial to the synthesis of chlorophyll b. Bulbil formed the largest number and the biggest propagation coefficient of P. ternata under red light showed that it could increase the production of P. ternata under red light.

Objective To evaluate the CT findings and classification of the Le Fort fracture. Methods Sixty-two cases with Le Fort fractures were studied with thin-slice high-resolution CT scanning and analyzed with three-dimensional(3D)imaging reconstruction.Results Of the 62 patients,10 had Le Fort type Ⅰ fracture,9 had Le Fort type Ⅱ fracture,8 had Le Fort type Ⅲ fracture,and 35 had various combinations of the three types of Le Fort fractures,including 18 Le Fort Ⅰ+Ⅱ fracture,7 Le Fort Ⅰ+ Ⅱ+Ⅲ fracture and 10 Le Fort Ⅱ+Ⅲ fracture.Fifty-five cases had associated multiple fractures in the maxillofacial region.On 2D CT images,Le Fort fracture manifested as multiple and complex fractures. Though 2D image was better than 3D image in accurately defining tiny fractures and fractures of deep structures,the diagnosis of Le Fort fracture could not be correctly made solely on 2D image.3D CT clearly and stereoscopically demonstrated the entire shape and orientation of Le Fort fracture,thus facilitating the correct classification of Le Fort fracture.Conclusion 3D CT image is important in providing information about the space relationship of Le Fort fracture,thus very valuable for the preoperative planning.

BACKGROUND: Cerebral infarction is commonly associated with blood stasis syndrome. Abnormal alternation of blood rheology is generally manifested as increased blood viscosity and hematocrit (HCT). In isometric hemodilution, a certain amount of red blood cell (RBC) is shifted by bleeding and simultaneously, isometric diluter is supplemented to reduce whole blood viscosity.OBJECTIVE: To observe the improvement of astragalus injection, the Chinese herb for qi tonification and isometric hemodilution on blood rheology in blood stasis syndrome of cerebral infarction.DESIGN: Randomized controlled experiment and case-control analysis were designed.SETTING: Union Hospital Affiliated to Tongji Medical College, Huazhong University of Science and Technology. PARTICIPANTS: In cerebral infarction group (infarction group), 64 inpatients of senile ischemic cerebral vascular disease were collected from Union Hospital Affiliated to Huazhong University of Science and Technology from March 2002 to March 2004. Al l of cases were aged over 60 years and were in conformity with the diagnostic criteria on blood stasis syndrome. According to random number table, routine treatment group (routine group) and the group of integrative therapy of Chinese and western medicine (experimental group) were divided, 32 cases in each one. 47 healthy people of similar age and diagnosed with routine physical examination were selected in normal control. METHODS: In routine group, cerebral infarction was treated with routine therapy, including extending capacity, reducing viscosity, resisting coagulation, blocking aggregation of platelet and dehydration and general symp tomatic supporting treatment. In experimental group, on basis of routine treatment, isometric hemodilution and astragalus injection, the Chinese herb for qi tonification were used. 10% of total blood amount (about 450-650 mL) was collected from vein, and colloid solution of same volume was injected intravenously. The treatment was applied once every 5 days, continuously for 3 times. Astragalus injection 50 mL mixed with physical saline 250 mL was intravenous dropped, once per day, continuously for 3 weeks. MAIN OUTCOME MEASURES: ① Comparison of indexes in bloodrheology before and after treatment in routine group and experimental group. ② Comparison of indexes in blood rheology between normal control and infarction group. RESULTS: According to intention management, 64 patients and 47 normal persons all entered result analysis. ① Comparison between infarction group and normal control: RVB, HCT and PFC (fibrinogen) were higher than normal control [(3.90±0.73), (3.40±0.28) mPa·s; (46.39±6.03) %,(42.61±2.91)%; (3.25±0.75), (3.08±0.46) g/L, P < 0.01, 0.05], MTIE (de formity index of RBC) was lower than normal control (0.958±0.006, 0.961 Shen H,Lu YD.Study on quantitative messurement of immunohistochemical ±0.004, P < 0.05). ② Comparison between routine group and experimental group: Difference in some indexes presented before the treatment. After treatment, RVB, HCT and PFC in experimental grou p were all lower than routine group [(3.90±0.52), (4.21±0.68) mPa·s; (43.80±3.29)%, (48.47±4.50)%; (3.31±0.60), (3.68±0.67) g/L, P < 0.01, 0.05]. CONCLUSION: Isometric hemodilution therapy and astragalus injection reduces blood viscosity, improves blood rheology and alleviates clinical svmptoms of blood stasis syndrome in senile cerebral infarction.
