Laser peripheral iridotomy ( LPI) is one of the main therapy for glaucoma due to its reliable efficacy of widening peripheral angle and therefore decreasing intraocular pressure by partially relieving pupillary block. The parameters of the anterior chamber angle following the LPI are the main evaluation indexes. At present,the detecting and diagnosis technique for the anterior chamber angle is deeply advancing, including gonioscopy, ultrasound biomicroscopy, anterior segment optical coherence tomography and Pentacam. These methods offer some useful parameters and also present with some limits in the application respectively in the evaluation of anterior chamber and angle structure. This review focuses on the application of Methods mentioned above and morphologic changes of anterior chamber and angle structure following the LPI.

Purpose To investigate the clinicopathological features, histogenesis, morphological characteristics, immunophenotypes and differential diagnosis of primary extragonadal yolk sac tumor ( eYST) . Methods Clinicopathological data, morphological charac-teristics and immunophenotypes results of 40 cases of eYST were retrospectively studied and the relevant literatures were reviewed. Re-sults All 40 patients, which included 24 male and 16 female, aged from 6 months to 42 years with a 12 years average age and 17 (42.5%) cases were over 12 years old. Mediastinum, sacrococcygeal, retroperitoneal, pineal gland and vagina were involved in 16 (40.0%), 12(30.0%), 5(12.5%), 4(10.0%) and 3(7.5%), respectively. All 40 cases included 32(80.0%) cases pure YSTs, while other 8(20.0%) cases contained other one or two types of germ cell tumor (GCT) components. Conclusions Primary eYST is rare, mediastinum and sacrococcygeal are the most common anatomic sites for eYST, and these mediastinal tumor patients are overwhelmingly confined to adult males, whose average age are significantly older than that in sacrococcygeal, retroperitoneal, pineal gland and vaginal tumor patients (P<0.05), while other sites eYST are restricted to prepubertal children. Adult eYST contain other types of GCT components in some cases, and children's counterparts are always pure YST. Extragonadal eYST manifestate pleomorphic histological features, which combine with immunohistochemical markers is definite value for diagnosis, differential diagnosis.

Operation rules of sterilizing are put forward.Responsible persons with working licenses are selected.The cleanout,packing,loading of pre-sterilized goods are standardized.Sterilizing effects(physical monitoring,chemical monitoring,biological monitoring,B-D test) are inspected.Requirements in maintenance and metrology test are raised.The content and methods for quality control of sterilized goods by using decontamination device are introduced systematically.It is instructive to enhance decontamination quality and lower infection rate in hospitals.

Objective To explore the prenatal ultrasonographic features of fetuses diagnosed as echogenic bowel and chromosomal abnormalities. Methods From September 2009 to June 2013, eighty cases diagnosed as echogenic bowel by prenatal ultrasound screening in our hospitals underwent chromosomal karyotype analysis and were followed up till fetal birth. The prenatal ultrasonographic features were carefully correlated with the postnatal findings. Results Prenatal ultrasoundand chromosomal findings of the 80 cases were:(1) Fifty-eight cases of fetuses with echogenic bowel alone (72.5%, 58/80, without chromosomal karyotype abnormalities). (2) Eleven cases of fetuses with additional ultrasound soft markers (13.8%, 11/80, without chromosomal karyotype abnormalities). The ultrasound examination revealed 8 cases of choroid plexus cysts, 1 case of single umbilical artery, 1 case of shorter nasal bone, and 1 case of echogenic intracardiac focus. (3) Five cases of fetuses with severe functional abnormalities or complex structural malformations and normal chromosomal karyotype. The ultrasound examination revealed 3 cases of structural cardiac malformations, 1 case of heart failure and 2 cases of central nervous system malformations. Of them,one case showed complex malformations (right ventricular dysplasia syndrome, cerebellar dysplasia and single umbilical artery), whereas the remaining 4 cases only involve single malformation. (4)Six cases had chromosomal abnormalities (7.5%, 6/80), including 3 cases of abnormal chromosome microdeletions, and 3 cases of abnormal chromosome numbers (1 21-trisomy syndrome, 1 18-trisomy syndrome, and 1 triploid syndrome). All of them had severe structural malformations and abnormal soft markers. The ultrasound examination revealed 2 cases of severe cardiac malformations, 2 cases of central nervous system malformations, 1 case of pericardial/peritoneal effusion, and 1 case of placental chorionic multiple hemangioma. One case of holoprosencephaly (donor of the twins) ended with intrauterine death. The associated abnormal soft markers include nuchal fold (NF) thickening, choroid plexus cysts, umbilical cord cysts, single umbilical artery, and placental chorionic hemangioma. Conclusions The fetuses with echogenic bowelaloneusualyhaveagoodprognosis.Insomecases,echogenicbowelmaydisappearduringvfolow-up.The fetuses complicated with severe structural malformations and chromosomal abnormalities have poor prognosis. For the fetuses diagnosed of echogenic bowel by prenatal ultrasound screening, systematic ultrasound examination should be carried out and clinical chromosomal karyotype analysis was suggested.

OBJECTIVE:To establish the method for the determination of particle size distribution of Budesonide nasal spray, and to analyze the consistency of particle size distribution of spray samples. METHODS:Water was used as dispersant for mixing and dispersing(1800 r/min). The particle sizes [d(0.1),d(0.5),d(0.9)] corresponded to accumulative particle size of 10%,50%and 90%were used as characteristic value. The distribution of granularity was determined by laser scattering method. The consisten-cy of particle size distribution of samples from 2 manufacturers (A,B) were analyzed among different batches or same batch of same manufacturer by SAS 9.3 statistical software. RESULTS:The mean values of d(0.1),d(0.5) and d(0.9) were 3.96 μm, 29.58 μm and 67.10 μm in manufacturer A. The mean values of d(0.1),d(0.5)and d(0.9)were 2.00 μm,7.53 μm and 28.51 μm in manufacturer B. By analysis,there was great difference in particle size of samples from 2 manufacturers. The particle size of the samples from manufacturer A were larger than that of manufacturer B. The consistency among different batches from manufacturer B was better,and the consistency among same batch were all good from 2 manufacturers. CONCLUSIONS:The established meth-od is suitable for particle size distribution of Budesonide nasal spray and the consistency analysis of particle size distribution.

Objective To investigate the level change and clinical significance of serum IL-6, IL-8 and IL-13 in the patients with lupus nephritis(LN). Methods The levels of serum IL-6,IL-8 and IL-13 were measured by enzyme linked immunosorbent assay (ELISA) in 56 patients with LN. Results The levels of serum IL-6,IL-8 and IL-13 in the patients with active LN were significantly higher than those in the patients with non-active LN and the controls, but had no significant difference between the patients with non-active LN and controls. The levels of serum IL-6,IL-8 and IL-13 in the patients with active LN were positively correlated with anti-dsDNA antibody titre and erythrocyte sedimentation rate, but negatively correlated with the serum levels of complements C 3 and C 4. Conclusion IL-6,IL-8 and IL-13 may be involved in the pathogenesis of lupus nephritis, can serve as a clinical reference index for activity of LN, and have important clinical significance in guiding LN therapy and improving LN prognosis.
