AIM: To observe the effects of scleral buckling surgery for retinal detachment under microscope and under indirect ophthalmoscope.
METHODS: Forty - six patients ( 46 eyes ) with rhegmatogenous retinal detachment were retrospectively analyzed. Twenty-six patients received surgeries under microscope was retrospectively analyzed and compared to that of 20 patients who received surgeries under indirect ophthalmoscope by the same operator.
RESULTS: No statistical difference was found in patients' operation method choice, including condensation reaction reattachment situation and the retina reset operation at a time ( P> 0. 05 ). The best corrected visual acuity of microscopic group after 1mo of operation was better than before operation, and the improving rate of vision after operation was higher than that of the traditional group (P<0. 05).
CONCLUSION:The curative effect of external approach microsurgery has the similar efficacy with the conventional external approach surgery, and gets better visual acuity.

? AlM: To analyze the reason of corneal epithelial implantation and ingrowth after laser in situ keratomileusis ( LASlK ) , and summarize the treatment experiences.
?METHODS: The clinical data of postoperative corneal epithelial ingrowth on 18 cases (30 eyes) from 1 256 cases (2 256 eyes) after LASlK were retrospectively analyzed in our hospital from January 2008 to December 2012. After the treatment of all eyes, patients’ general visual quality scores before and after treatment were analyzed.
?RESULTS:There were 18 cases ( 30 eyes ) with corneal epithelial implantation and ingrowth after LASlK, and the incidence rate was 1. 3%. ln the 18 cases (30 eyes), there were 12 eyes corneal flap epithelial ingrowth caused by postoperative trauma, 12 eyes caused by multiple corneal flap flush, 2 eyes caused by intraoperative irregular corneal flap, and nothing special for 4 eyes. The classification of corneal epithelial ingrowth of 30 eyes:grade I, 11 cases (18 eyes);gradeII, 4 cases (8 eyes);grade Ⅲ, 3 cases ( 4 eyes ) . Grade I-II were treated with TobraDex eye drops and intraocular pressure lowering drug. Grade Ⅲ firstly were treated by drugs, otherwise by surgery if it didn’t improve. After treatment, 8 cases (13 eyes) epithelial ingrowth disappeared from 11 cases ( 18 eyes ) , 3 cases ( 5 eyes ) implanted epithelial tumor shrank in grade l;epithelial implantation of 2 cases (4 eyes) in grade II disappeared, implantation degree of 2 cases (4 eyes) reduced to grade I;2 cases (2 eyes) in grade Ⅲ had 0. 5 ~ 1mm wide flap edge shallow gray ribbon 1 mm inside the limbus, visual acuity was 0. 8 ~1. 2, 1 case ( 2 eyes ) treated with curettage corneal epithelial implantation and endophytic epithelium hadn’t relapsed in the follow-up. After the treatment, 18 cases of corneal epithelial ingrowth got lower visual quality scores than those before therapy (Hc=10. 511, P<0. 01).
?CONCLUSlON: Operation standardized, postoperative early detection and aggressive treatment are important for prevention and treatment of complications after LASlK.

Objective To investigate the influence of early hyperbaric oxygen (HBO) therapy on cerebral edema and neural function in patients after minimally invasive surgery for intracerebral hemorrhage (ICH).Methods A random number table was used to divide 148 ICH surgery patients into a control group (n =75) and a treatment group (n =73).In the treatment group,HBO was administered in 51 cases 6-24 hours after surgery and then once a day for twenty days.Cerebral edema volume was measured by brain CT before the operation and on the 3rd,7th,14th and 21st day after the surgery.Neurological impairment was scored at the same time points.Results Average cerebral edema volume was significantly smaller in the treatment group than in the control group on the 7th,14th and 21st days,but not on the 3rd day.The neurological impairment scores (NIS) after therapy were significantly lower than that before therapy in both groups.The two groups' average scores were not significantly different before the operation or on the 3rd day,but they were significantly lower in the treatment group thereafter.Conclusion Early HBO therapy can significantly reduce cerebral edema and contribute to nerve functional recovery in patients after minimally invasive ICH surgery.

OBJECTIVETo investigate the effect and mechanism of Bufei Qingyu Granule (BQG) in mollifying the skin of scleroderma model mice.

METHODSScleroderma model induced with bleomycin in BALB/C mice 8-weeks old were administered with different dose of BQG for 26 days. The pathological changes of the mice skin were observed.

RESULTSTreatment with low, medium and high dose of BQG showed a tendency to ameliorate the thickened dermis in scleroderma mice but without statistical significance. Medium and high dose of BQG reduced the perivasculitis of dermis and alleviated the reduction or deletion of accessory structure, such as hair follicle and sweat gland. And the spleen index was lower markedly in mice treated with BQG of any dose than that in the untreated model mice (P < 0.05).

CONCLUSIONBQG could ameliorate the sclerosed skin in model mice and prevent the occurrence of splenomegaly.

This study aims to investigate the biotransformation of Epimedium brevicornu flavonoids under the effect of hydrolytic enzymes in vitro. Snailase was mainly used to hydrolyze E. brevicornu flavonoids, and HPLC was used to determine the content of the main flavonoids in E. brevicornu flavonoids. The data results showed that the main known flavonoids included icariin, epimedin A, epi-mendin B and epimendin C, which were completely transformed into baohuoside I, sagittatoside A, sagittatoside B and 2"-O-rhamnosyl-icariside II in 1-2 h, respectively. Their transformed products were continuously hydrolyzed over time. In conclusion, snailase could transform E. brevicornu flavonoids into secondary glycoside or aglycone under 37 degrees C in pH 6.0 HBSS balanced salt solution in 2 h. Moreover, its enzymatic hydrolysates were consistent with intestinal metabolites.

Objective To construct and purify the recombinant protein of platelet-activating factor acetylhydrolase(PAF-AH) isoformⅠ,and study the enzyme activity by different substrates. Methods The ? subunit of PAF-AH isoformⅠwas cloned and expressed in E.coli.Exogenously expressed recombinant protein was purified to SDS-PAGE homogeneity,and its activity was identified by arylesterase detection.Phenylacetate,l-O-hexadecyl-2-deoxy-2-thioacetyl-sn-glycero-3-phosphocholine(2-Thio PAF) and 1-myristoyl-2-(4-nitrophenylsuccinyl) phosphatidylcholine(the latter two were commercial plasma PAF-AH substrates) were used for the substrate identification.The plasma type PAF-AH was served as positive control. Results Recombinant protein of ? subunit of PAF-AH isoformⅠwas successfully constructed and expressed in E.coli after purification.Compared with positive control,the recombinant protein could hydrolyze phenylacetate and 2-Thio PAF,but could not hydrolyze 1-myristoyl-2-(4-nitrophenylsuccinyl) phosphatidylcholine.Conclusion Recombinant protein of ? subunit of PAF-AH isoformⅠcan be successfully constructed.There are differences in the substrate specification to the two commercial PAF substrates for PAF-AH isoformⅠand plasma type PAF-AH,which provides a quick method to differentiate PAF-AH isoformⅠfrom plasma type PAF-AH.

Objective To evaluate the predicting value of the marker of endothelial injury: plasma matrix metalloproteinase-9( MMP-9) and high sensitivity C-reactive protein( hsCRP) level on the progression of acute anterior circulating territory infarction progressing to malignant middle cerebral artery infarction (m-MCAI). Methods 90 patients with acute anterior circulating territory infarction, in which 46 patients progressed to m-MCAI, were collected and sampled consecutively. The plasma MMP-9 and hsCRP of all patients were determined by ELISA and immunotur-bidimetry,respectively,at admission. And the clinical characters and cranial CT features of the patients were analyzed. Results At admission,the plasma MMP-9 level in the patients with m-MCAI(242.0 ±58.0)ng/ml was significantly higher than that in the patients with non m-MCAI( 169.0 ± 50.0) ng/ml( P < 0. 01) ,the plasma hsCRP level in the patients with m-MCAI(6.25 ±1.2) ng/ml was significantly higher than that in the patients with non m-MCAI( 1.55 ± 0.9) mg/ml( P <0. 01).Conclusion The increased level of plasma MMP-9 and hsCRP could be predictors for the m-MCAI proceeding.
