To study corneal lymphangiogenesis after corneal transplantation, corneal allogenic transplantation models were established in rats. 8 female Wister rats were used as donors, and 16 Sprague Dawley (SD) rats were used as recipients and 2 SD served as controls. Corneal lymphangiogenesis and hemangiogenesis was examined by electron microscopy 1 and 2 weeks after corneal penetrating transplantation, and the expression of lymphatic vessel endothelial receptor (LYVE-1) was examined 1, 3, 7, 14 days after the transplantation respectively. In addition, 19 allograft failed human corneas were examined by 5'-nase-alkaline phosphatase (5'-NA-ALP) double-enzyme-histochemistry staining to detect corneal lymphangiogenesis and hemangiogenesis. By immunohistochemistry for LYVE-1, it was found that blown lymphatics were localized in the stroma 3 days after the corneal transplantation. With electron microscopy, new lymphatic vessels and blood vessels were found 1 and 2 weeks after the corneal transplantation. By 5'-NA-ALP enzyme-histochemistry, corneal hemangiogenesis was found in all allograft failed human corneas and 5 of 19 (26.3 %) cases had developed corneal lymphangiogenesis. It is concluded that corneal lymphangiogenesis is present after corneal transplantation, which may play an important role in allograft rejection.

In order to investigate the efficiency of a new quantitative head-band formed ocular compressor to reduce intraocular pressure (IOP), ocular compression by this new reducer with 40 mmHg for 10 min was performed on 87 cataractous eyes of 78 cases. The changes of IOP (87 eyes) and anterior chamber depth (ACD) were observed. There was a significant decrease of IOP and increase of ACD within 30 min after decompression (P < 0.001). The mean decrease of IOP was 5.62 +/- 2.41 mmHg and the mean increase of ACD was 0.18 +/- 0.09 mm within 5 min after decompression. The IOP 5 min after decompression had no significant difference with that 10 min after decompression (P > 0.05). IOP below 10 mmHg could last for about 15 min. This apparatus had been successfully applied to 80 eyes for extracapsular cataract extraction. It was suggested that this device had the advantages of safety, accurate quantification, reliable effect, casually adjusting pressure according to various demands and time-saving.

Objective To determine the clinical efficacy of the combination of Aidi injection and chemotherapy in patients of advanced non-small-cell lung cancer (NSCLC). Methods One hundred and twenty three patients with stage ⅢB/Ⅳ NSCLC complying with diagnosis standard were eligible.Those patients were randomly divided into treatment group (63 patients) and control group (60 patients). Both of groups received NP regimens( NVB 25 mg/m2, ivgtt, d1,d8; DDP 25 mg/m2, ivgtt, d1-3, watering). In treatment group,patients received Aidi injection (50 ml, ivgtt, d1-10) combined with NP regimens. Then some indexes were observed, including outcomes in the overall response rates, adverse drug reaction, quality of life. Results In treatment group, outcomes in the overall response rates were 50.8 %, 5 patients were completely remitted(CR),27 patients were partly remitted(PR). In control group, outcomes in the overall response rates were 35.0 %(3 CR, 18 PR). Gastrointestinal reaction and bone marrow depression of treatment group was lower than control group. Quality of life of treatment group was higher than control group. The difference was significant between two groups (P＜0.05). Conclusion This Aidi injection plus chemotherapy combination is effective against NSCLC with mild toxicities and quality of life can be improved.

Objective To investigate alterations in epigenetic regulation in B cells in subacute cutaneous lupus erythematosus (SCLE).Methods Peripheral blood mononuclear cells (PBMC) were isolated from the peripheral venous blood of SCLE patients and healthy donors with density gradient centrifugation.B cells were isolated with CD19 micro beads and protocols provided by the manufacturer.Total RNAs were isolated with RNA kits.The expressions of silence information regulator 1 (Sirt1) mRNA were investigated with quantitative real time polymerase chain reaction (PCR).Results The levels of Sirt1 mRNA were significantly increased in SCLE B cells relative to healthy controls (P ＜ 0.01).Conclusions Histone modifications appear abnormal in B cells in SCLE.

Objective To explore the early diagnostic significance of anti-cyclic citrullinated peptide(CCP) antibody and hidden rheumatoid factor immunoglobulin M(HRF-IgM) detected by ELISA in patients with juvenile rheumatoid arthritis(JRA). Methods The synthesized CCP was used as the antigen to detect anti-CCP antibody. Anti-CCP antibody and HRF-IgM were detected dynamically in 27 patients with early diagnosed JRA and their specificity and sensitivity were determined for early diagnosed JRA by calculating the positive predicting value (PPV) and negative predicting value (NPV). Results The total positive rate of anti-CCP antibody and HRF-IgM were 58.5 % and 65.0 % respectively in patients with JRA. The sensitivity of HRF-IgM was more predominant than that of anti-CCP antibody. There was a positive correlation between the positive rate of antibodies and the subtype of JRA. The specificity of anti-CCP antibody for predicting early JRA was superior to that of HRF-IgM. When using these two tests in combination, the PPV predicting rate of early JRA was 93.7 % . Conclusions Both anti-CCP antibody and HRF-IgM are elevated in patients with JRA, which show positive correlations with the subtype of the disease. The specificity of anti-CCP antibody testing is considerably higher for diagnosing early JRA, and when it was used together with HRF-IgM testing, the PPV for JRA can be raised further.

Objective To investigate the relativity of the lupus anticoagulant(LAC), anticadiolipin antibody(aCL) - IgG,aCL-IgM,aCL-IgA levels and clinical symptoms of systemic lupus erythematosus (SLE), and to determine the significance of the LAC level in the prognosis of idiopathic thrombocytopenic purpura (ITP) by detecting the LAC and aCL-IgG, IgM,IgA levels in 310 children with SLE and 249 children with ITP. Methods Kadin-cephalin clotting time(KCCT) and correcting test to detect the plasma LAC level and to the serum aCL- IgG, IgM, IgA levels with enzyme - linked immunosorbent assay. Results In SLE group, there were 66.1% patients with higher LAC among whom 45.9% patients suffered from lupus nephritis , aCL subantibody level elevated in 46.8% patients (90.2% IgG and/or IgM) serum; 46.9% and 11.7% patients suffered from central nervous system diseases and blood diseases with SLE respectively. In ITP group, 36.2% patients with LAC positive were diagnosed as SLE by detecting the serum antinuclear antibody level, and 7.6% suffered from SLE subsequently in the period of 2 months to 2.4 years. Conclusions The LAC and aCL subantibody levels may have an important relativity with the clinical symptoms of SLE. The LAC is the predominant pathologic autoantibody in patients with lupus nephritis, and the aCL subantibody( IgM, IgG) levels were related to lupus thromboangiitis. The IAC level of children with ITP should be monitored in order to determine the prognosis of the disease as soon as possible.

To explore the expression and clinical significance of molecular chaperone heat shock protein 90 (HSP90) in peripheral blood mononuclear cells (PBMC) and plasma level of interleukin-6 (IL-6) in patients with systemic lupus erythematosus (SLE), HSP90 was detected in PBMC by Western blot assay and the plasma level of IL-6 was measured by ELISA in 38 SLE patients and 20 normal controls. The correlation analysis was performed between the SLE disease activity index (SLE-DAI) and the expression of HSP90 and IL-6. The results showed that there was increased expression of HSP90 in the SLE patients. The active SLE group exhibited higher HSP90 levels (0.82+/-0.10) than the inactive SLE group (0.54+/-0.09) (P<0.01). The expression of HSP90 in normal control group (0.37+/-0.11) showed significant statistical difference as compared to both the inactive and active SLE groups (P<0.01, P<0.01, respectively). The plasma level of IL-6 exhibited a significant increase in both the inactive and active SLE groups (28.99+/-1.74 pg/mL, 44.58+/-9.15 pg/mL, respectively) compared with normal control group (P<0.01, P<0.01, respectively). The expression of HSP90 and IL-6 in SLE patients showed significant positive correlation with SLEDAI scoring (r=0.80, P<0.01: r= 0.74, P<0.01, respectively). In addition, there was a positive correlation between the level of IL-6 and HSP90 in SLE patients (r=0.86, P<0.01). The increased expression of molecular chaperone HSP90 and IL-6 may play an important role in the pathogenesis of SLE by regulating autoimmunity.

The present study aimed to compare the clinical efficacy of a 0.4% carbomer gel and 1% carboxymethyl cellulose (CMC) containing artificial tears in treatment of dry eye patients. Sixty subjects with mean age of 45.89 years who had symptoms and signs of dry eye were enrolled in this prospective, investigator-masked and stratified random sampling study. The subjects were divided into two parallel groups with 30 subjects (60 eyes) in each group. One group received carbomer gel, and the other group received 1% CMC containing artificial tears. Subjects received the drops 3 to 4 times or more per day for 3 months. At the first visit time, the precorneal residence time of these two drops was measured. The efficacy was assessed by comparing the subjective symptoms (ocular dryness, foreign body sensation, burning sensation and pain), and the objective test results of tears breakup time, Schirmer's test and corneal fluorescein staining prior to the study and after the treatment. As a result, the ocular residence time of carbomer gel was significantly longer than that of 1% CMC (P<0.001). Most of the primary subjective symptoms and objective test results were improved after treatment in both carbomer gel group and 1% CMC group. As to the improvement of each symptom and objective test result, carbomer gel was more effective than 1% CMC group (P<0.01). In conclusion, carbomer gel had longer precorneal residence time and was more effective than 1% CMC in the treatment of patients with dry eyes.
