The relation between the critical radius and the particle size distribution for generalized Ostwald type ripening processes whereby the mass transfer coefficient is modelled by a power law was derived. The critical radius is determined by the growth rate, the mass transfer coefficient and the mass balance, and is independent of whether the limiting stationary growth regime has been obtained.

AIM: To analyze the associated factors of poor vision after phacoemulsification operation.
METHODS:Clinical data of cases with poor vision after cataract phacoemulsification combined with IOL implantation from 341 patients(418 eyes) during Jan. 2015 to Jan. 2016 in our hospital were collected and logistic correlation analyzed.
RESULTS: The incidences of postoperative low vision were 10. 3% for one month after operation. Forty-three eyes were reported low vision, and 41 of 43 the patients with postoperative low vision had fundus oculi disease before operation, which included 20 eyes ( 48. 8%) with age-related macular degeneration, 16 eyes(39. 0%) with diabetic retinopathy, 3 eyes ( 7. 3%) with glaucomatous optic neuropathy, 1 eye(2. 4%) with pathologic myopia of retinopathy and 1 eye ( 2. 4%) with branch retinal vein occlusion.
CONCLUSION: The associated factors of poor vision after phacoemulsification operation are preoperative eye diseases and the nuclear hardness, and preoperative eye diseases may be the main causes of postoperative low vision. Comprehensive examination should be attached importance to, and be careful in the operation to decrease the harm for visual performance.

Iron uptake mechanism of Vibrio alginolyticus was primarily investigated. V.alginolyticus could survive in the medium with high-concentration iron chelator. The strain of V. alginolyticus isolated from diseased fish produced more siderophore than that from marine environment. The extract of siderophore from V. alginolyticus could stimulate the growth of Escherichia coli mutant AN93. Under iron limitation,the growth rate was decreased and several outer membrane proteins were induced. Adding iron into the iron-limited medium the normal growth could be recovered.

Objective It is difficult to differentiate tumors in upper GI muscularis proporia, such as GI stromal tumors (GISTs) , leiomyomas and schwannomas. We performed EUS guided fine needle aspirations (FNA) and immunohistochemical evaluation of these tumors in upper GI muscularis proporia. Methods We selected 35 Patients with lesions in upper GI muscularis proporia by EGD and EUS. We assessed the shape , size, and position of the lesions and the status of metastasis. After excluding blood vessel between the lesions and the fine needle, EUS FNA were carried out and immunohistochemical staining for CD-117 (c-kit) , CD34 and smooth muscle actin ( SMA) was performed. Results All patients were performed EUS FNA and enough specimens were obtained in 31 patients. The other 4 failed, although we tried it for several times. Among the 31 patients, Cytology and immunohistochemisty demonstrated 21 GISTs and 10 leiomyomas. All the results were evaluated by surgery. The sensitivity is 88. 6% , and the speciality is 100%. No complication occurred. Conclusion EUS-guided FNA and immunohistochemical evaluation is an accurate method for diferential diagnosis of tumors in upper GI muscularis propria.
