?AIM: To discuss the effect of laser exposure on visual acuity and macula.?METHODS: Retrospective and consecutive case series. A retrospective analysis of 11 patients (11 eyes) with laser retinal injury was carried out from January 2014 to June 2015 in Ophthalmology Department of No. 474 Hospital of Chinese PLA. All individuals underwent visual acuity, best corrected visual acuity ( BCVA ) , and spectral-domain optical coherence tomography ( SD-OCT) for macular at first visit, and fundus fluorescein angiography ( FFA ) , visual field, and multifocal electroretinogram ( mf ERG ) were perform if necessary. Symptomatic therapies, supportive therapies and pars plana vitrectomy ( PPV ) were performed depended on the patient’s condition. The patients were followed-up at 1, 3 and 6mo after the first visit, and patients were undertaken visual acuity, BCVA, macular SD-OCT and so on.?RESULTS: Eight patients ( 73%) were under 18 years old and all patients were young males, who were injured by laser pointers when playing. Three patients ( 27%) over 18 years old were injured accidentally at work. Ten (91%) patients’ BCVA were ≤0. 3, while one ( 9%) patient’s BCVA was higher ≥0. 3. Full-thickness macular holes ( the diameter 224-519 μm ) were detected in 10 patients (91%), while sub-foveal RPE changes and IS/OS injury in 1 patient ( 9%) . Macular hole with traction or cystoid edema in 6 eyes (55%) were received PPV, while the other 5 eyes ( 4 eyes with stable macular hole and 1 eyes with RPE injury ) received conservative treatment. Macular hole closed successfully in 1 eye ( 17%) after PPV, while macular hole in the other 5 eyes ( 83%) were stable after PPV of which the cystoid edema faded. The 4 patients with macular hole and 1 patient with RPE injury were stable during follow-up period. However, the BCVA in all patients had no significant improvement at end.?CONCLUSION: Exposure to laser devices could lead to severe macula injury that could reduce central vision, which is permanent.

OBJECTIVETo study the antalgic and antiphlogistic functions and mechanism of ronggudingtong (RGDT) plaster (traditional Chinese medicine).
METHODSThe painful models were established with hot plate test or acetic acid writhing and the inflammatory models were established with daubing dimethylbenzene on auricle or injecting formaldehyde in toe or synovial envelope to study the antalgic and antiphlogistic functions of RGDT Plaster. The total protein and leukotriene B4(LTB4) in inflammatory exudate were detected to investigate the antalgic and antiphlogistic mechanism of RGDT plaster. The mice were randomly divided into different groups (n = 11), on the basis of drug using, the indexes of pain threshold, swelling degree were observed. Sixty-six mice were used to establish gasbag synovitis model and randomly divided into normal control group,model control group, positive control group (Voltaren gel 0.8 mg/d)and low/medium/high dosage RGDT plaster treating groups(30 mg/d, 60 mg/d, 120 mg/d).
RESULTS30 mg/d, 60 mg/d,120 mg/d RGDT plaster could upgrade the pain thresholds, remit auricular and foot swelling (P < 0.05, P < 0.01), and degrade total protein and LTB4 in inflammatory exudates (P < 0.05, P < 0.01).
CONCLUSIONRGDT plaster has some antalgic and antiphlogistic functions, and one of the mechanisms is depressing synthesis of LTB4.

AIM: To investigate the alterations of tear film after sutureless large incision manual cataract extraction (SLIMCE). METHODS: Sixty-eight SLIMCE operation eyes were studied with slit-limp microscope, break- up time (BUT), SchirmmerⅠtest (SⅠt),and fluorescence(FL) to observe the alterations of tear film at different time points in postoperation. Impression cytology and microphoto-analyses technique were also applied to observe the goblet cells at different time points postoperation(7,14,30,60,90 days). RESULTS: Subjective complaint of dry eye within 90 days after the operations were significantly increased compare with preoperations(5-27,23,19,16,13; 2-16,14,8,6,3). The schirmmer Ⅰ test were greatly increased in 14 days postoperation(10.1±4.5;15.0±4.7,13.8±5.7),the mean scores of fluorescence increased (0-17,9,5;0-8,3,1) and the mean break-up time decreased in 30 days post-operation(10.3±2.2;5.5±2.3,7.0±2.4,7.9±2.2) (P<0.05). CONCLUSION: SLIMCE operation have effect on the stability of tear film.

OBJECTIVETo investigate the effect of Radix Astragali Injection on apoptosis of lymphocytes and immune function in treating patients with systemic lupus erythematosus (SLE).
METHODSEighty SLE patients were randomly assigned into the routine treatment group (RT) treated with conventional therapy and the Radix Astragali treated group (RA) treated with Radix Astragali Injection besides routine treatment. The expressions of Fas and Bcl-2 antigen on lymphocytes and the changes of T lymphocyte subsets in peripheral blood before and after treatment were observed.
RESULTSAfter treatment, the expression of Fas antigen on lymphocytes significantly lowered (P < 0.01), and that of Bcl-2 antigen, CD4+ lymphocyte subset and CD4+ / CD8+ ratio significantly increased in both groups (all P < 0.01). However, the changes of Fas antigen expression, CD4+ and CD4+ / CD8+ ratio were more significant in the RA group than those in the RT group (P < 0.05).
CONCLUSIONRadix Astragli Injection can enhance the inhibitory function of corticosteroid/immunosuppressant on apoptosis, and regulate the ratio and function of T lymphocyte subsets to normal range, which may be a useful approach for enhancing the efficacy of treatment to SLE.

Reversed phase high performance liquid chromatography with diode array detector was employed for simultaneous determination of five main index components and specific chromatograms analysis in Xiaochaihu granules with a linear gradient elution of acetonitrile-water (containing 0.1% phosphoric acid) as mobile phase. The results showed that five main index components (baicalin, baicalein, wogonoside, wogonin, enoxolone) were separated well under the analytical condition. The linear ranges of five components were 0.518 - 16.576, 0.069 - 2.197, 0.167 - 5.333, 0.009 - 0.297 and 0.006 - 0.270 mg x g(-1), respectively. The correlation coefficients were 0.999 9, and the average recoveries ranged from 95% to 105%. Twelve common peaks were selected as the specific chromatograms of Xiaochaihu granules with baicalin as the reference peak. There were good similarities between the reference and the ten batches of samples. The similarity coefficients were no less than 0.9. The analytical method established is highly sensitive with strong specificity and it can be used efficiently in the quality control of Xiaochaihu granules.
