To evaluate the clinical efficacy of corneal lamellar debridement combined with sutureless amniotic membrane transplantation for the treatment of superficial fungal keratitis.
●METHODS:Totally 22 cases (22 eyes) with superficial fungal keratitis were referred to our hospital from April 2012 to October 2013. The patients with persistent cornea ulcer after treatment of local and systemic antifungal drugs underwent corneal lamellar debridement combined with sutureless amniotic membrane transplantation, and the recipient bed was covered with an amniotic membrane using fibrin sealant during the operation. All patients were still given topical antifungal therapy for 1 -2mo after operation. The followed- up time was 3mo or above. We observed the corneal healing and amniotic membrane adhesion by split lamp microscope, and investigated the transformation of amniotic membrane and fungal infection recurrence with confocal microscope.
●RESULTS: Corneal edema and anterior chamber reaction of 21 patients disappeared gradually, and no amniotic membrane graft dissolved and shed off within 1-2wk postoperatively. Two weeks after operation, the graft integrated into the corneal and the corneal wounds' thickness increased gradually, the corneal epithelium reconstructed and corneas became clear. Four weeks after operation, the corneal scarring developed gradually and fluorescence staining was negative. Nineteen cases' amniotic membranes that adhered with the cornea dissolved 4wk after operation. There were different degrees of corneal nebula or macula remained 3mo postoperatively. All patients' vision improved in varying degrees, except in 1 case with fungal keratitis who had been cured by lamellar keratoplasty.
●CONCLUSlON:Corneal lamellar debridement combined with sutureless amniotic membrane transplantation can effectively remove the foci of inflammation, improve the local efficacy, shorten the operation time, relieve the postoperative reaction, and promote cornea union, which is an effective way to treat superficial fungal keratitis.

Objective: To analyze the influencing factors of whole blood colloid osmotic pressure (COP) and predict reference range of plasma protein for safe COP to guide clinical infusion of protein in critically ill patients. Methods: Physical data and blood gas analysis of 405 patients were collected. hTe patients were divided into 2 groups by COP: group A (COP≤18 mmHg) and group B (COP>18 mmHg). The serum proteins including total protein (TP), albumin (Alb), globumin (Glb) and ifbrinogen (FIB) were detected. Results: APACHE II of group B was signiifcantly lower than that of group A (P<0.05). hTe survival rate, TP, Alb, Glb and FIB of group B were significantly higher than these of group A (P<0.05).Standardized regression coeffcient of Alb, Glb and FIB was 0.518,0.283 and 0.113 (P<0.05); the 95% reference range of 4 types of protein level in group B: Alb>23.3 g/L,Glb 12.6-37.6 g/L and FIB 1.3-8.7 g/L; 5 reformed equations were made. Conclusion: The main influencing factors of COP include Alb, Glb and FIB. We can use the reference range of 4 types of protein level to guide the clinical management of protein agents, and reformed equations can be used to preliminarily forecast COP in critically ill patients.

OBJECTIVE: To evaluate the sustained efficacy of 2-year sublingual immunotherapy (SLIT) and 1 year after 2-year SLIT in children with allergic rhinitis (AR). METHOD: This study is a randomized, open and prospective trial. One hundred twenty children (between 4 and 11 years old) suffering from AR duo to mite were chosen from November, 2008 to June, 2009 in department of otolaryngology in our hospital divided into two groups: 60 underwent 2-year course of SLIT and one year follow-up combined with 3-year drug therapy as SLIT group; 60 received only drug therapy as control group. The patients were evaluated at three time points (baseline, end of SLIT and 1 year after SLIT discontinuation) regarding symptom scores including total nasal symptom score (TNSS), sneezing, rhinorrhoea, nasal obstruction, nasal itching and total medication scores (TMS) and adverse reaction. RESULT: (1) At the end of SLIT, the symptom scores excepting sneezing and total medication scores in SLIT group are obviously lower than those in control group (P < 0.01). At 1 year after SLIT discontinuation, all of the score including sneezing (P < 0.05) in SLIT group are lower than those of control group. (2) At the end of SLIT and 1 year after SLIT discontinuation, all of the scores are lower than those at baseline in SLIT group (P < 0.01); the scores were no different in SLIT group between the end of SLIT and 1 year after SLIT discontinuation (P > 0.05). But at the end of SLIT and 1 year after SLIT discontinuation, TMS was higher than it at baseline in control group (P < 0.01). At 1 year after SLIT discontinuation, nasal obstruction score was higher than it at baseline (P < 0.05). CONCLUSION SLIT can obviously improve the AR and the efficacy can sustain after 1-year SLIT discontinua tion. Drug increased in 3 years without SLIT.

Objective To investigate the morphology and quantity of melanin and blood vessels in chloasma lesions by using reflectance confocal microscopy(RCM)and dermoscopy, and to explore the relationship of melanin and blood vessels with lesion color. Methods RCM was used to evaluate the quantity and distribution of melanin in lesions of 135 patients with chloasma, and to observe the morphology of melanin and dendritic melanocytes in 54 of the 135 patients, and dermoscopy was performed to assess the quantity and morphology of blood vessels in lesions of the 54 patients. Statistical analysis was carried out by Spearman correlation analysis to assess the relationship of melanin and blood vessels with lesion color. Results Increased quantity of melanin was observed in both the epidermal layer and dermo?epidermal junction in all the 135 patients, and in only the superficial dermis in 36(27%)patients. No patients showed increased quantity of melanin in only the dermis without epidermal involvement. Among the 54 patients, there was a positive correlation between the quantity score and morphology score of melanin(r=0.73, P<0.001), between the quantity score and morphology score of blood vessels(r=0.87, P<0.001), as well as between the total melanin score and total blood vessel score(r=0.554, P<0.001). Lesion color was positively correlated with the quantity and morphology of melanin(r = 0.51, 0.39, respectively, both P < 0.05)and blood vessels(r = 0.46, 0.44, respectively, both P<0.05). Conclusions RCM and dermoscopy can be used to evaluate melanin and blood vessels in chloasma lesions. There is a positive correlation between the quantity and morphology of melanin and between those of blood vessels in chloasma lesions, and lesion color is positively correlated with the quantity and morphology of melanin and blood vessels.
