AIM: The reasons of explicit and occult Descemet's membrane detachment ( DMD ) after phacoemulsification were analyzed and the therapeutic measures were further provided.
METHODS:A total of 31 cases diagnosed as explicit and occult DMD between Jan. 2013 and Apr. 2016 received the injection of sterile air into anterior chamber by 1-3 times, and were followed up for 3mo to observe the recoveries of cornea.
RESULTS: A total of 30 cases recovered with no visual impairment and other related complications. One case which refused being treated resulted in bullous keratitis.CONCLUSION:Both the internal and external factors can influence the operation effect of explicit and occult DMD after phacoemulsification. Early detection and timely treatment play important roles in improving patients'visual acuity. Early examination of anterior segment OCT or UBM for intractable corneal edema is helpful to find the occult DMD with different degree and work out the targeted therapies.

AlM: To evaluate the clinical efficacy and safety of capsular tension ring ( CTR) combined with iris hooks in eyes with large traumatic zonular dialysis or weakness that underwent micro -incision coaxial phacoemulsification with posterior chamber ( PC ) intraocular lens ( lOL) implantation.METHODS: This prospective study was carried on 21 patients ( 21 eyes ) with traumatic cataract and traumaticzonular dialysis (<180 degrees determined pre-or intra-operatively ) in our hospital from January 2011 to September 2014. After CCC, 1-4 iris hooks might be used probably and a in-the-bag CTR was inserted in order to maintain or re-establish an extended capsular diaphragm before or at any time during cataract removal. Then micro-incision coaxial phacoemulsification with foldable acrylic PC lOL implantation was performed. Zonular dialysis range, posterior capsule rupture, vitreous loss, pupil size, best corrected visual acuity ( BCVA ) , intraocular pressure ( lOP ) in the pre- and post-operative periods and postoperative lOL decentration were observed after operation.RESULTS: The mean follow-up period was 3 ~12mo. No serious postoperative complication was found. BCVA in our cases: <0. 3 in 1 eye, 0. 4~0. 7 in 15 eyes ,>0. 8 in 5 eyes. lOPs were in normal range too. The lOLs in 20 eyes remained the required position to the final follow- up examination except one eye in which the PC lOL was dislocated into vitreous cavity due to a postoperative spontaneity PCR, and in which vitrectomy and lOL suture fixation was performed.CONCLUSlON: ln cases of cataract associated with traumatic zonular dialysis (<180.) , by setting the rational parameters of phacoemulsification, the CTR and iris hooks are found to be efficient in preventing lOL decentration and reducing operation complication. ln our cases, the CTR combined with iris hooks is relatively safe application.

Danshen is one of the traditional Chinese herbal medicines and nas a long history or being used clinically in the treatment of cardiovascular and cerebrovascular conditions such as coronary heart disease and angina pectoris. Tanshinone IIA is a derivative of phenanthrene-quinone isolated from Danshen. It has been reported to be the major bioactive compound of Danshen and has diverse biological effects. Recent studies demonstrated that tanshinone IIA had neuroprotective effects on experimental ischemic stroke through its antiinflammatory, anti-oxidant, anti-apoptosis effects and its inhibitory effect on excitatory amino acid toxicity. In this review, we summarized all the recent progresses on the protective effect of tanshinone IIA on cerebral ischemic stroke. Hopefully, this article will throw some light on further study and application of tanshinone IIA.

Objective: To study the effect of nitrogen (N), phosphorus (P), and potassium (K) fertilizers on the sclerotial formation and germination of southern blight of Coptis chinensis so as to provide scientific basis for its integrated pest management (IPM). Methods: Preparation of different concentrations of N, P and K was added into soil and the mycelium and sclerotia were put on the soil, and then the effect of the fertilizers on the sclerotial formation and germination was observed. Results: The treatment of CO(NH 2)2 and NH4HCO3 had significant inhibition on sclerotial formation and germination. The treatment of NaH 2PO4, KCl, and KNO3 showed the facilitation in various degrees to promote the sclerotial formation and germination. The treatment of KH2PO4 had no significant effect on sclerotial germination, but it had significant inhibitory activity to sclerotial formation. Conclusion: In the production, the partial N, while less K and P fertilizers should be put to control the sclerotial formation and germination of southern blight of C. chinensis.
