Objective To explore the clinical effect of small incision extracapsular cataract extraction combined with implantation of artificial lens and phacoemulsification combined with implantation of artificial lens for patients with cataract.Methods One hundred and ten patients (142 eyes) with cataract were selected,55 patients (69 eyes) were treated with small incision extracapsular cataract extraction combined with implantation of artificial lens (observation group),and 55 patients (73 eyes) were treated with phacoemulsification combined with implantation of artificial lens (control group).After treatment,the corrected vision and quality of life were observed 1-week,1-and 3-month after operation,and the complications were recorded.Results The vision 0.6-1.0 of 1-week,1-and 3-month in observation group were 34 eyes (49.3％,34/69),61 eyes (88.4％,61/69) and 63 eyes (91.3％,63/69) respectively,in control group were 37 eyes (50.7％,37/73),64 eyes (87.7％,64/73) and 65 eyes (89.0％,65/73) respectively,there were no statistical differences (P ＞0.05).The quality of life score 1-week,1-and 3-month in observation group were (87.5 ± 10.7),(91.2 ± 5.3),(94.3 ± 5.8) scores respectively,in control group were (85.9 ± 11.5),(90.6 ± 6.7),(94.5 ± 6.0) scores respectively,there were nostatistical differences (P ＞ 0.05).The rate of complications in observation group was 23.2％ (16/69),in control group was 37.0％ (27/73),there was statistical difference (P ＜ 0.05).Conclusions The vision recovery and quality of life in cataract patients treated with small incision extracapsular cataract extraction combined with implantation of artificial lens are similar to treated with phacoemulsification combined with implantation of artificial lens.However,with fewer complications,small incision extracapsular cataract extraction combined with implantation of artificial lens is a more safe and reliable treatment method.

Objective:To explore antitumor mechanism of a recombinant vaccinia virus expressing human carcinomembryonic antigen(rV CEA).Methods:C57bl/6 mice were immunized three times with rV CEA.Six weeks later,the splenocytes from rV CEA immunized donors were adoptively tranfered in sublethally irradiated CEA + HePa bearing recipients,meanwhile the antiumor effect of the donor splencytes in virtro was detected.Results:Splenocytes from rV CEA immunized donors expressed strong antiumor activity in CEA positive tumorbearing recipients,whereas W VV immunized and nonimmune donor cell did not.The antiumor activity was abolished when immune T cells were depleted before splencytes transfer.Conclusion:It was demonstrated that antiumor acivity induced by rV CEA was essentially mediated by immune T cells which were activated by CEA specific immune response.Adoptive immunotherapy strategies may have implications for both the study of rV CEA and the development of potential clinical applications for tumor immunotherapy.

To analyze the prescription and medication regularities of traditional Chinese medicines in the treatment of melancholia in the Chinese journal full text database (CNKI), Wanfang Data knowledge service platform, VIP, Chinese biomedical literature database (CBM) in based on the traditional Chinese medicine inheritance support platform software, in order to provide reference for further mining traditional Chinese medicines for the treatment of melancholia and new drug development. The traditional Chinese medicine inheritance support platform software V2.0 was used to establish the prescription database of traditional Chinese medicines for treating melancholia. The software integrated data mining method was adopted to analyze four Qis, five flavors, meridian distribution, frequency statistics, syndrome distribution, composition regularity and new prescriptions. Totally 358 prescriptions for treating melancholia were analyzed to determine the frequency of prescription drugs, commonly used drug pairs and combinations and develop 22 new prescriptions. According to this study, prescriptions for treating depression collected in modern literature databases mainly have the effects in soothing liver and resolving melancholia, strengthening spleen and eliminating phlegm, activating and replenishing blood, regulating liver qi, tonifying spleen qi, clearing heat and purging heat, soothing the mind, nourishing yin and tonifying kidney, with neutral drug property and sweet or bitter flavor, and follow the melancholia treatment principle of "regulating qi and opening the mind, regulating qi and empathy".

AIM: To research the correlation factor of the anterior segment values of eyes with different axial lengths.METHODS: In this study, 697 cases 697 eyes were included.According to axial length we divided all the cases into short axial length group, normal axial length group, mild long axial length group, moderate long axial length group and severe long axial length group.The relevant indicators of the anterior segment values of patients in the five groups was comparatively analyzed.RESULTS: In the short axial length group, the anterior chamber volume (ACV) showed a significantly negative correlation with age;anterior chamber depth (ACD) showed a significantly negative correlation with age.In the normal axial length group, the ACV showed a significantly negative correlation with age and a significantly positive correlation with axial length(AXL);the anterior chamber angle (ACA) showed a significantly negative correlation with age and a significantly positive correlation with AXL, and a significantly positive correlation with corneal curvature;the ACD showed a significantly negative correlation with age and a significantly positive correlation with AXL.In the mild long axial length group, the ACV showed a significantly negative correlation with age and a significantly positive correlation with AXL, and a significantly negative correlation with corneal curvature;the ACA showed a significantly negative correlation with age and a significantly positive correlation with AXL, and a significantly positive correlation with corneal curvature;the ACD showed a significantly negative correlation with age and a significantly positive correlation with AXL.In the moderate long axial length group, the ACV showed a significantly negative correlation with age;the ACA showed a significantly positive correlation with AXL;the ACD showed a significantly positive correlation with AXL.In the severe long axial length group, the ACV showed a significantly negative correlation with age.There were no significant differences on ACV, ACA and ACD among mild long axial length group, moderate long axial length group and severe long axial length group (P>0.05), while the difference between other groups was significant (P<0.05).CONCLUSION: There has a correlation between the anterior chamber values (ACV, ACA, ACD) age and AXL for eyes which AXL were 22-27mm, while the correlation would disappear as the AXL became shorter or longer.There was a significant growth trend of anterior chamber values for eyes with AXL <27mm.

AIM: To compare the visual acuity and contrast sensitivity of eyes with different corneal spherical aberration implanted with the same aspherical IOL and evaluate the effect of different ocular spherical aberration on visual performance after phacoemulsification.
METHODS:It was a prospective case series study. Forty-six eyes of thirty-nine age-related cataract patients in our department were included. The patients were divided into 3 groups according to the value of preoperative corneal spherical aberration. Eyes with corneal spherical aberration≤0. 2μm were assigned to group A, those with corneal spherical aberration >0. 2μm and ≤0. 3μm to group B, and those with corneal spherical aberration≥ 0. 3μm to group C. All patients underwent phacoemulcification and recieved AcrySof IQ aspheric IOL. Uncorrected visual acuity ( UCVA ) , best-corrected visual acuity( BCVA) , contrast sensitivity, and total ocular higher - order aberrations for a 6. 0mm pupil were recorded 3mo postoperatively. ANOVA were used to analyze the data.
RESULTS: There were no significant differences in UCVA and BCVA between the 3 groups (P=0. 287, 0. 115). Contrast sensitivity was no statistically significant difference between the 3 groups at any spatial frequency under photopic、 mesopic, and mesopic with glare conditions (P>0. 05). With a 6. 0mm pupil diameter, root mean square values for total ocular higher - order aberrations were lower in groups A and B than that in group C (P=0. 000). The difference of total ocular spherical aberration was statistically significant between the 3 groups (P=0. 000). Coma and trefoil were similar between the groups (P=0. 788,0. 590), with no statistically significant differences.CONCLUSION:Implantation of the same aspherical IOL in eyes with different corneal spherical aberration results in similar visual acuity and contrast sensitivity. Small differences of ocular spherical aberration after phacoemulsification have no effect on visual performance.
