AIM:To explore efficacy of the different kinds of artificial tears treatment in patients with xerophthalmia after phacoemulsification combined with intraocular lens implantation.METHODS:Totally 280 patients (280 eyes) with xerophthalmia after operation in our hospital from January 2015 to June 2016 were selected.According to the different treatment methods, they were divided into control group (n=70;treated with tobramycin and dexamethasone eye ointment 3 times per day for 1wk, levofloxacin eye drops 3 times per day for 1wk, pranoprofen eye drops 4 times per day for 1mo), polyacrylic acid group (n=70;besides the treatment of control group, polyacrylic acid was used 4 times per for 1mo), polyethylene glycol group(n=70;besides the treatment of control group, polyethylene glycol was used 4 times per for 1mo) and sodium hyaluronate group (n=70;besides the treatment of control group, sodium hyaluronate was used 4 times per for 1mo).The tear film break up time (BUT), Schirmer Ⅰ test (SⅠt), symptoms of dry eye and corneal staining in four groups were observed.RESULTS:(1) BUT:The BUT of the four groups significantly increased after treatment(P<0.05);that of polyacrylic acid group, polyethylene glycol group, and sodium hyaluronate group was different compared with control group(P<0.05);the BUT in sodium hyaluronate group was significantly higher than the other groups after 2wk of treatment(P<0.05).(2) SⅠt:SⅠt of the four groups significant increased after treatment(P<0.05);that of polyacrylic acid group, polyethylene glycol group, and sodium hyaluronate group was different compared with control group(P<0.05);and the SⅠt in sodium hyaluronate group was significantly higher than other groups (P<0.05).(3) Xeroma score:the scores of dry eye significantly decreased after treatment in the four groups(P<0.05);that of polyacrylic acid group, polyethylene glycol group, and sodium hyaluronate group was different compared with control group(P<0.05);and the scores of the sodium hyaluronate group after 3wk was significantly lower compared with other groups(P<0.05).(4) Corneal staining score:the scores significantly decreased after treatment in the four groups(P<0.05);at 1 and 2wk after treatment the corneal staining score had not statistically different among the four groups (P>0.05);sodium hyaluronate group was significant lower than other groups in corneal staining score at 3wk and 1mo after treatment(P<0.05).CONCLUSION:Artificial tears in the treatment of xerophthalmia after cataract phacoemulsification combined with intraocular lens implantation has better clinical efficacy, which contains sodium hyaluronate may be the better than others.

OBJECTIVETo evaluate the accuracy and precision of 4 methods including Hemacytometer, Makler chamber, Cell-VU chamber, and computer-aided semen analysis for determining sperm concentration.

METHODSLatex bead solutions with concentrations known as (35 +/- 5) x 10(6)/ml and (18.0 +/- 2.5) x 10(6)/ml and semen samples (n = 54) were counted by the above 4 methods and the results were then compared.

RESULTSMean bead concentrations for Hemacytometer, Makler, Cell-VU chambers and CASA were (44.84 +/- 4.86), (52.36 +/- 7.78), (39.70 +/- 4.76), (28.53 +/- 2.06) x 10(6)/ml respectively for the standard solution containing (35 +/- 5) x 10(6)/ml, and (21.04 +/- 1.87), (24.54 +/- 3.67), (19.09 +/- 2.02), (14.62 +/- 0.95) x 10(6)/ml respectively for a standard solution containing (18 +/- 2.5) x 10(6)/ml. The results of Cell-VU chamber were consistently similar and close to the standard solutions, while those of Hemacytometer, Makler chambers were overestimated, and those of CASA were underestimated. The coefficients of variation for Hemacytometer, Makler, Cell-VU chambers and CASA were 10.81%, 14.86%, 12.80%, and 7.22% respectively for a higher standard solution, while 8.89%, 14.96%, 10.58%, and 6.50% respectively for a lower standard solution. CASA has the lowest CV%. When semen samples were counted, the results of Hemacytometer, Makler, Cell-VU chambers and CASA were (76.98 +/- 59.90), (63.89 +/- 53.84), (45.28 +/- 34.52), (41.96 +/- 31.93) x 10(6)/ml respectively. There wasn't any significant difference either between Cell-VU chamber and CASA (P = 0.71), or between Hemacytometer and Makler chamber (P = 0.14), while there was significant difference between Cell-VU chamber or CASA and Hemacytometer or Makler chamber (P < 0.05 or P <0.01).

CONCLUSIONWhen counting semen sample, there wasnt any significant difference between Cell-VU chamber and CASA. Each laboratory can select its own proper method for manual or computer-aided analysis.

OBJECTIVETo study the inhibition effect of celastrol on neovascularization.

METHODSThe effect of celastrol on the in vitro proliferation of endothelial cell of vessel (ECV) was examined by MTT assay. The effect of celastrol on endothelial cell migration, tube formation on Matrigel and Chick chorioallantoic membrane angiogenesis was also examined. Matrigel plug assay was used to evaluate the effect of celastrol on angiogenesis in vivo.

RESULTSThe proliferation of ECV was inhibited significantly by celastrol with IC(50) being 1.33 microg/ml. Celastrol inhibited endothelial cell migration and tube formation in a dose-dependent manner. Celastrol also inhibited angiogenesis both in Matrigel plug of mouse model and in chick chorioallantoic membranes.

CONCLUSIONCelastrol, which can inhibit angiogenesis, could be developed as an antiangiogenic drug.
