?Proliferative diabetic retinopathy ( PDR ) is a group of disease characterized by neovascular disease complication of diabetes mellitus. Neovascular diseases of eye are one of the major causes of blindness of the world. Recent studies showed that vascular endothelial growth factor ( VEGF) and pigment epithelium-derived factor ( PEDF ) are now accepted as the key cytokine in the development of diabetic retinopathy. Recent progress in the investigation of VEGF and PEDF of PDR are summarized in this review.

Objective:To investigate the application value of lauromacrogol in the treatment of varicose veins of lower limb.Methods:The medical records of 75 patients (75 affected limbs) with varicosis of great saphenous vein of lower limbs confirmed between September 2013 and September 2015 were analyzed retrospectively.According to the treatment regimen,the patients were divided into two groups.Among them,33 cases (33 limbs) treated by ultrasound guided injection of foam sclerosing agent lauromacrogol were included in the lauromacrogol group while 42 cases (42 limbs) treated by high ligation of great saphenous vein combined with stripping were included in the operation group.The operation time,intraoperative blood loss,off-bed time,treatment costs and incidence of postoperative complications were recorded.Patients were followed up for 6 to 12 months after operation,and the recurrence rate was recorded.Results:The operation time,off-bed and length of hospital stay of the lauromacrogol group were shorter than those of the operation group;the intraoperative blood loss and hospitalization expenses were less than those of the operation group (P＜0.05);The incidence rates of subcutaneous hematoma and skin numbness in the lauromacrogol group were significantly lower than those in the operation group (P＜0.05);The 12-month recurrence rate in the lauromacrogol group (12.12％) was lower than that in the operation group (33.33％)(P＜0.05).Conclusion:Injection of foam sclerosing agent lauromacrogol is an alternative minimally invasive therapy for treating varicosis of great saphenous vein of lower limbs.

OBJECTIVETo verify the pharmacological hypothesis of prescriptions by studying the targeted distribution of major components in stewed rhubarb in the rat model with acute pancreatitis (AP).

METHODNormal SD rats (control group, n = 5) and the AP model induced with intraperitoneal cerulein (model group, n = 5) were taken as the experimental objects. Rats of the two groups were orally administered with stewed rhubarb granules (20 g x kg(-1)). Their heart, liver, spleen, lung, kidney and pancreas were collected two hours after the administration. Such constituents as emodin, chrysophanol, physcion, rhein and aloe-emodin and their concentrations in each tissue homogenate were detected by high performance liquid chromatography-mass-mass.

RESULTAloe-emodin and physcion in stewed rhubarb whose concentrations in liver and kidney of normal rats were higher than that in pancreatic tissues, while the distribution spectrums and concentrations of the remaining components in pancreatic tissues had no significant difference with that of other organs. The concentrations of emodin, aloe-emodin, rhein and chrysophanol in stewed rhubarb in pancreatic tissues of the AP model group were higher than that in other tissues and organs, while their concentrations in pancreatic, renal and splenic tissues were notably higher than that in the normal group.

CONCLUSIONIn the conditions of AP, effective components in stewed rhubarb show a targeted distribution feature in pancreas, which provides experimental basis for the pharmacological hypothesis of prescriptions.

Background Lattice corneal dystrophy (LCD) is a progressive disease,whose clinical features are varied in different stages.It is rarely be reported that clinical findings of different stages and factors of promoting the occurrence and development on LCD in a family.Objective The aim of this study was to identify the characteristics of the pedigree and clinical features of different stages in a LCD family,and further to discuss its influence factors.Methods A cross-sectional study was performed in this study.A Chinese family with LCD was enrolled in Shenzhen Eye Hospital from 2015 to 2016.Questionnaires for disease-related history,visual acuity measurement,ocular anterior segment examination and color photography were carried out for all the members of the family.In addition,anterior segment OCT (AS-OCT),laser scanning confocal microscope and corneal endothelium microscope were used to observe the morphology of corneal stroma and changes of corneal endothelial cells.The pedigree chart was drawn by Cyrillic2.1 software and analyzed based on Mendel law.Results This family included 5 generations of 73 members.Patients with LCD were found in each generation with similar morbidity in different gender,which followed the law of autosomal dominant inheritance.Eleven patients were found in 49 members related with Ⅲ1 of this family with the prevalence rate of 22.45％ and onset age at 21-50 years old,and the course of disease was 3-34 years.All of the members had no systemic disease except for two patients (Ⅲ 1 and Ⅲ 5) with hypertension.In the early stage of LCD,some bifurcate striolae appeared in the patients' corneal stroma without symptoms for many years.In the progressive stage,there was corneal irritation symptom accompanying with vision's decrease in the eyes with LCD.The bifurcate striolae were increased,widened and interwoven into lattice lines that the boundaries gradually became fuzzy,then corneal macula was formed because of recurrent corneal infiltration,and eventually resulted in corneal leucoma.High reflection corresponding to the pathologic region was showed by laser scanning confocal microscope and AS-OCT.No significant differences were found in corneal endothelial cell density and the percentage of hexagonal cells between LCD patients and normal phenotype families (t =1.887,P=0.075;t=-0.719,P =0.481).Penetrating keratoplasty was performed in a patient with corneal opacity and serious corneal opacity occurred near the surgical incision one year after the surgery.One patient was diagnosed as LCD 2 years after laser assisted in-situ keratomileusis.One patient was a welder.Conclusions LCD is autosomal dominant inheritance in the family.The clinical manifestations of LCD in the early,progressive and late stage can be seen in the pedigree,which offers a reference for ophthahnologists.Corneal surgery and lesion may induce the onset or aggravation of LCD.

AlM: To observe clinical effect of vitrectomy with intravitreal ranibizumab for the treatment of diabetic retinopathy ( DR) .
METHODS:From February 2011 to February 2013, there were 90 cases in our hospital diabetic retinopathy patients withvitrectomy surgery. lt was randomly divided into observation group ( 45 cases ) and control group ( 45 cases ) . Two groups of patients were performed vitrectomy. Patients in observation group were injected intravitreal ranibizumab before surgery, then vitrectomy was underwent for diabetic retinopathy. Vitrectomy was only underwent in control group.
RESULTS:The patients in observation group with good effect accounting for 71% (32/45) and good rate was 89%(40/45 ), which were significantly higher than that in control group 51% ( 23/45 ) , 71% ( 32/45 ) . Differences were statistically significant ( P < 0. 05 ). Amount of bleeding was 9. 64 ± 2. 27mL, intraocular pressure was 13. 64 ± 3. 27mmHg. lt was significantly less than that in control group 10. 21 ± 3. 14mL, 16. 00 ± 3. 14mmHg. Differences were statistically significant (P<0. 05).
CONCLUSlON: The vitrectomy with intravitreal ranibizumab treatment of diabetic retinopathy can not only reduce blood loss, but also reduce edema and improve effectiveness and safety. lt's worth recommending for clinical practice.

The study is a paticular embodiment of Chinese patent medicine based on biopharmaceutics classification system of Chinese materia medica (CMMBCS) , focusing on assessment of synchronization issues of dissolution that may affect the timing of the multicomponent absorption. The accumulative dissolution percentages of nine components in Gengen Qinlian tablets in different dissolution solvents and times were determined by HPLC. The dissolution curve was drew and its similarity was evaluated by similarity factors (f2) and cluster method. Results in this experiment showed that the components that peak 7 and peak 8 (baicalin) represented had poor similarity with the reference peak 2 (puerarin). Their similarity factors were both 43 in water dissolution media and 31 and 45 in pH 7.4 dissolution media, respectively. Components that peaks represented had better similarity with the reference peak 2 (puerarin) in other medium. It illustrated that components that peak 3,4,5,6 (berberine) represented had fully synchronous dissolution characteristics with the reference peak 2 (puerarin), components peak 1 and 9 represented had nearly fully synchronous dissolution characteristics with the reference peak 2 (puerarin), while components that peak 7 and 8 (baicalin) represented had no synchronous dissolution characteristics with the reference peak 2 (puerarin).
