The SRY gene from buffalo (Bubalus bubalis) genome was amplified by the polymerase chain reaction ( PCR) with primers based on the sequence of Hostein SRY gene. The amplified fragment was 2005 bp include 5UTR ( 1 - 504bp) and 3'UTR(1196 - 2005bp). And the amplified fragment was cloned and sequenced. Sequence analysis showed that the coding region of SRY gene (505 - 1195bp) from buffalo was highly homologous with those of other bovine counterpart genes (96% homology) , especially in the HMG box region (99%homology). It was found that there were only signal on male buffalo genome on Southern blot,which indicate SRY gene are highly conservative on evolves.

Objective:To observe influence of alprostadil injection on contrast-induced nephropathy (CIN) in high risk patients after percutaneous coronary intervention (PCI).Methods: A total of 263 CIN high risk (CIN risk score ≥16 scores) patients were selected.According to random number table, patients were randomly divided into routine treatment group (n=121, received routine hydration therapy) and alprostadil group (n=142, received additional alprostadil injection based on routine treatment group).Serum creatinine (SCr), glomerular filtration rate(GFR), cystatin C (CysC) and β trace protein (β-TP) level before, 48h and 72h after PCI were measured and compared, and incidence rate of CIN, percentage of blood purification therapy and mortality were compared between two groups.Results: Compared with before PCI, there was significant rise in SCr level and significant reduction in GFR in both groups on 48h and 72h after PCI (P<0.01 all);Compared with routine treatment group, there were significant reductions in levels of SCr [72h: (190.04±28.92) μmol/L vs.(141.10±21.18) μmol/L], and significant rise in GFR [72h: (26.0±4.4) ml/min vs.(36.4±4.9) ml/min], and levels of CysC[72h: (1.75±0.74) mg/L vs.(1.47±0.55) mg/L] and β-TP [72h: (1.53±0.50) mg/L vs.(1.22±0.38) mg/L] significantly decreased in alprostadil group on 48h and 72h after PCI, P<0.05 or <0.01;there were significant reductions in incidence rate of CIN (30.6% vs.18.3%) and percentage of blood purification therapy (10.7% vs.3.5%) in alprostadil group, P=0.001, 0.045 respectively.There was no significant difference in mortality between two groups, P=0.728.Conclusion: Alprostadil injection can significantly improve kidney function, reduce incidence rate of CIN and percentage of blood purification therapy in CIN high risk patients after PCI, which is worth extending.

AIM: To observe effect of the iris location to femtosecond - combined wavefront guided LASIK for myopia and astigmatism.?METHODS:The patients with astigmatism >1. 0D during the same time and followed up for 1a were selected. A total of 129 eyes in 67 patients were treated under iris location with femtosecond-combined wavefront guided LASIK ( experimental group) and 161 eyes in 82 cases with femtosecond-combined wavefront guided LASIK ( control group) . Laser cutting went with the same laser machine. The uncorrected visual acuity ( UCVA ) , best corrected visual acuity ( BCVA) , and wavefront aberration between the two groups were compared at 1, 3, 6mo and 1a after surgery.?RESULTS:At 1 and 3mo after surgery, the number of patients with better postoperative UCVA than preoperative BCVA between the two group showed a statistically significant difference (χ2=6. 423, P=0. 011,χ2=14. 431, P=0. 01 ); at 1d and 1mo after surgery, the residual astigmatism showed a statistically significant difference between two groups (t=1. 98, P<0. 05; t=2. 23, P<0. 05). At 3, 6mo and 1a after surgery, the differences on the change of residual astigmatism between the two groups weren’t significant ( P > 0. 05 ). At 6mo and 1a after surgery, the differences on UCVA between the two groups weren’t significant ( P > 0. 05 ). Until 1a after surgery, the root mean square ( RMS ) of high order wavefront aberration of the two groups, spherical aberration and coma aberration ( COMA ) were all enhanced compared to before surgery(P<0. 05). At 1, 3mo after surgery, the RMS showed a statistically significant difference between two groups (P<0. 05). At 1, 3, 6mo, 1a after surgery, the increase of COMA in experimental group was significantly lower than that in control group (P<0. 05).? CONCLUSION: Iris location technology applied in femtosecond - combined wavefront guided LASIK for myopia and astigmatism, can make the vision recovery faster, the RMS of high order and COMA increase less, the residual astigmatism less, show better and more stable treatment effect.

AIM:To contrast analysis of postoperative variation of corneal posterior surface heights after Femtosecond LASlK ( FS - LASlK ) and small incision lenticule extraction ( SMlLE) for high myopia.
●METHODS: Sixty-seven cases of high myopic patients (132 eyes) operated with laser corneal refractive in our hospital from May to Dec. in 2015 (-6. 00D≤spherical equivalent degree≤-10. 00D) were selected and divided into FS-LASlK group and SMlLE group. The thickness of corneal flaps at FS-LASlK and the thickness of map at SMlLE were designed to be 110μm. Corneal posterior surface heights were examined by Pentacam at preoperation, postoperative 3 and 6mo after FS-LASlK and SMlLE operation. Surface height changes after preoperative, postoperative 3 and 6mo were compared by measuring Pentacam corneal analysis system.
●RESULTS: Six months after operation, the FS-LASlK posterior corneal surface height was 6. 47 ± 1. 65mm, significantly higher than 5. 20 ± 1. 32mm before operation. SMlLE posterior corneal surface height was 6. 40 ± 1. 33mm, significantly higher than 5. 18 ± 1. 25mm before operation, the differences were statistically significant( P<0. 05). Six month after surgery, two methods of corneal surface height variation obtained was 1. 29 ± 1. 28mm and 1. 22 ± 0. 89mm, there was no significant difference ( P>0. 05).
●CONCLUSION:After FS-LASlK and SMlLE, the corneal posterior surface is protrusive. FS - LASlK is slightly obvious than SMlLE in early period. The stability of the posterior surface is better after SMlLE.
