AIM: To compare the efficacy of different locations scleral tunnel incision in phacoemulsification cataract on preoperative corneal astigmatism.
METHODS:Totally 90 patients (94 eyes) in our hospital who had undergone the phaco-surgery from March 2013 to October 2014 were divided into two groups. The group A was those with 3. 2mm scleral tunnel incision at the direction of 10:00 ~11:00 points. The group B was those with 3.2mm scleral tunnel incision at the steepest corneal meridian. Incision was not sutured. Corneal astigmatism status of preoperative and postoperative at different times were detected by corneal refractive. The impact of different surgical incision on postoperative corneal astigmatism was compared. In the two groups, patients with preoperative corneal astigmatism<1. 00D, 1. 00 ~2.00D and > 2. 00D were compared respectively. The changes of the uncorrected visual acuity and corneal astigmatism at postoperative 1wk, 1 and 3mo were observed.
RESULTS:The uncorrected visual acuity of the patients who were in the group B preoperative corneal astigmatism <1. 00D and 1. 00 ~ 2. 00D was better than that in the group A. The postoperative corneal astigmatism of the patients who were in the group B preoperative corneal astigmatism <1. 00D was lower than that in the group A.
CONCLUSION: On the basis of preoperative corneal astigmatism, 3. 2mm scleral tunnel incision at the steepest corneal meridian to some extent can correct preoperative corneal astigmatism < 1. 00D, and accordingly improve the uncorrected visual acuity.

OBJECTIVETo explore the mechanism of natural moxibustion on regulating immune imbalance in asthma rats.

METHODSSeventy SD male rats were divided into a normal group, a placebo group, a dexamethasone group, a big-cake for long-course moxibustion group, a big-cake for short-course moxibustion group, a small-cake for long-course moxibustion group and a small-cake for short-course moxibustion group, ten rats in each one. The rat model of asthma was established by egg albumen sensitization and stimulation in all the groups except the normal group. The natural moxibustion was used in all moxibustion groups, in which big cake of 1 cmX 1 cm size was used in the big-cake groups and small cake of 0.5 cmX 0. 5 cm size was used in the small cake groups. According to relevant acupoints, the natural moxibustion was performed, 5 h per time, once a day. Four times of treatment was considered one course, and three courses were required in the long-course groups and one course was required in the short-course groups. Intraperitoneal injection of dexamethasone was applied in the dexamethasone group, which had the same course as long-course moxibustion group. After the treatment, changes of EOS in peripheral blood of asthma rats were observed; enzyme linked immunosorbent assay (ELISA) was applied to test the contents of IgE, IL-4 and IFN-gamma in the lung tissue; real-time Q-PCR method was adopted to measure the expression level of transcription factor T-bet and GATA binding protein 3 (GATA-3) in the lung tissue.

RESULTSCompared with the normal group, the EOS in whole blood as well as IL-4 and IgE in plasma were all increased in the placebo group (all P< 0. 01), IFN-gamma in plasma was obviously decreased (P<0. 01); while the levels of EOS, IgE and IL-4 were significantly reduced (all P<0. 01), the content of IFN-gamma was increased (P<0. 01) in all moxibustion groups and dexametnasone group. Compared with the normal group, the expression of T-bet mRNA in the placebo group was significantly reduced (P<0. 01). Each treatment group could significantly increase the expression of T-bet mRNA and reduce that of GATA-3 mRNA (P<0. 01). Compared with the short-course moxibustion groups, the expression of T-bet mRNA was obviously increased in the long-course moxibustion group and dexamethasone group (both P<0.01), and that of GATA-3 mRNA was reduced (P<0.01). There was no significant difference between long-course moxibustion group and dexamethasone group (P> 0. 05), and also no significant difference could be seen between big-cake moxibustion group and small-cake moxibustion group (P>0. 05).

CONCLUSIONThe natural moxibustion could obviously reduce airway inflammation in asthma rats. With time passing, the efficacy is enhanced, indicating evident timeliness, which has no apparent relationship with the size of moxibustion cake.

Objective To investigate the role of peripheral blood lymphocyte apoptosis through Fas/ Fas ligand pathway in the development of viral myocarditis. Methods Twenty-five viral myocarditis (VMC) and 25 healthy children were chosen for study. The apoptosis percentage in peripheral blood iymphocytes was quantitatively examined, flow cytometry with Annexin V/PI double parameter was used. And the expressions of Fas and Fasl protein in peripheral blood lymphocytes were analyzed with flow cytometry. Results The percentage of apoptosis in peripheral blood lymphocytes in children with VMC [(0. 6976 ± 0. 1109)%] was significantly higher than that of healthy children [(0. 1288 ± 0. 1069) %] (t = 18.459, P ＜ 0.001). Moreover, the apoptosis cell percentage showed a significant positive correlation with the serum levels of myocardium enzyme (creatine kinase-MB, lactate dehydrogenase, creatine kinase, hydroxybutyrate dehydrogenase)(r =0. 817 ,P ＜0. 01 ;r =0. 785 ,P ＜0.01 ;r =0. 726 ,P ＜0. 01 ;r =0. 712 ,P ＜0. 01). The expression of Fas and Fasl protein in VMC patients(2. 8804 ± 0. 3020,4. 4496 ± 0. 4836) were higher than those of health children(2. 1300 ±0. 6200,0. 1238 ±0. 0384) ,which had significant difference(t = 17. 321 ,P ＜0. 001 ;t' =44. 577, P ＜ 0. 001). The apoptosis percentage of peripheral blood lymphocytes in children with VMC showed a significant positive correlation with the Fas and Fasl protein expression in peripheral blood lymphocytes(r =0. 972, P ＜ 0. 01; r = 0. 958, P ＜ 0. 01). Conclusion Apoptosis percentage of peripheral blood lymphocytes increases among children with VMC, probably because immune response decreased or it is related with the degree of myocardium damaged. Fas and Fasl play an important role in apoptosis of peripheral blood lymphocytes in children with VMC.

Objective To study the effect of millimeter wave radiation on human hepatoma cell. Methods BEL7404 hepatoma cells were cultured in vitro and randomly divided into 4 groups: the control group, the group radiated by millimeter wave for 30 min, the group treated with Fluorouracil(5 FU), and the group radiated by millimeter wave and treated with 5 FU simultaneously at same time. The ability of 35.8 GHz millimeter wave to induce the apoptosis of hepatoma cell was evaluated by analyses of fluorescence microscopy, DNA fragmentation assay and flow cytometry assay. Results BEL7404 cells radiated by the millimeter wave had the typical characteristics of apoptosis. Comparaed with the control group [(3.21? 1.06)%], the apoptosis rates were higher in 30 min radiating or/and 5 FU groups[ (14.33? 2.66)%, (18.58? 2.57)%, (27.91? 3.66)%]. Poly adp ribose polymerase(PARP) was found to be cleavaged in all the cells in millmeter wave radiation or/and 5 FU groups. Conclusion Radiation of 35.8 GHz could induce apoptosis of BEL7404 cell in vitro, and could act synergistcally with 5 FU treatment.

Objective To study the expression of proliferating cell nuclear antigen (PCNA), CDK4 and P16 on rat hepatocellular carcinoma by millimeter wave radiation. Methods Fourty male Wistar rats were randomly divided into four groups. Group one to three were feeded by diethylnitrosamine (DEN). Group one was a tumor control group. In group two and three the liver was directly radiated by 35.8 GHz, 100 mW/cm 2 millimeter wave for 20 min, twice a week for 10 or 5 weeks. Group four was a normal control radiated group. Fourteen weeks later all rats were sacrificed to undergo serological test and immunohistochemical stain of liver. Results The serum levels of ? glutamyltransferase in group two and three were lower than that in group one. Adenocarcinoma was only existed in group one by histological examination of liver tissue. Other groups of DEN exposure only had basophilic and eosinophilic nodules. Liver tissue expression of PCNA and CDK4 in group two and three were significantly lower than in group one, but the expression of P16 in group two and three was higher than that in group one. Conclusions Radiation with millimeter wave can partially inhibit cell proliferation and suppress the DEN induced hepatocellular carcinoma in rats.

Objective To investigate the characteristics and analyze the differences of choroidal neovascularization (CNV) image between exudative age-related macular degeneration (AMD) and central exudative chorioretinopathy (CEC) using optical coherence tomography (OCT). Methods Twenty-three eyes of 22 patients with exudative AMD and 20 eyes of 19 patients with CEC, which were diagnosed as CNV using fundus fluorescein angiograph (FFA) or indocyanine green angiograph (ICGA), were exami- ned by OCT. The size of CNV and the thickness of retinal neurosensory layer in foveola were measured by OCT software. Results On OCT image, CNV had three main types of morphological features including simple CNV, CNV with serous retinal neurosensory layer detachment and CNV with choroidoretinal exudation. Exudative AMD mainly showed CNV with choroidoretinal exudation (56.52%) and CEC showed simple CNV (90 0%). The thickness of retinal neurosensory layer in foveola of patients with exudative AMD was thicker than that of patients with CEC and the size of CNV of patients with exudative AMD was larger than that of patients with CEC. Negative correlation was found between retinal neurosensory layer thickness in foveola and vision in both groups (?=-0.521, P =0.001). Conclusions There were certain discrepancy in morphology and area involved of CNV between exudative AMD and CEC on OCT images.
