AIM: To observe the clinical efficacy and safety of vincamine sustained release capsules on non- arteritic anterior ischemic optic neuropathy ( NAION) . · METHODS: Patients who were diagnosed with monocular onset NAION in acute stage from January to September 2015 were divided into two groups. Routine treatment such as steroid pulse therapy and neurotrophic treatment were given to all the patients. Vincamine was added to the treatment group patients with 30mg twice a day for 3mo. The best corrected visual acuity ( BCVA), mean deviation ( MD) of visual field, retinal nerve fiber layer ( RNFL ) , ganglion cell complex ( GCC ) , pattern visual evoked potential ( PVEP ) and OCT results were analyzed before and after the treatment. ·RESULTS:Totally 42 eyes of 42 patients were enrolled in our study. There were 27 patients in the treatment group, aged from 33 to 79 years old, the average value was 55. 55± 11. 83 years old. The control group has 15 patients, aged from 40 to 70 years old, the average value was 55. 71 ± 10. 06 years old. There were no statistical differences between the two groups in the baseline. After 3mo of the treatment, MD value of the two groups were lower compared with the baseline, the difference was statistically significant in the treatment and control group respectively (t= 2. 342, 2. 692; P = 0. 027, 0. 041). The difference of PVEP amplitude and potential of the two groups before and after the treatment were not statistically significant. The thickness of retinal nerve fiber layer and the ganglion cell complex were all lower than the baseline, and the difference was statistically significant (P<0. 001). The treatment of the two groups were both effective, the treatment group has better treatment effect than the control group. Adverse events related to the treatment of vincamine had not been found. ·CONCLUSION:Vincamine is helpful in the treatment of non-arteritic anterior ischemic optic neuropathy.

OBJECTIVETo evaluate the orthopedic effect of presurgical nasoalveolar molding (PNAM) devices on the palatal deformities in unilateral complete cleft lip and palate (UCCLP) patients.

METHODSThree groups with 19 patients each were studied. All samples in groups A and B were non-syndromic UCCLP children. Group A was treated with PNAM prior to operation. Group B was untreated prior to operation. Samples in group C were normally developed nose and lip palate infants aged three months. The orthotopic palate photos before and after PNAM treatment for group A, as well as pre-operative photos of groups B and group C, were taken and measured. All statistics were analyzed using SPSS 21.0.

RESULTSPNAM treatment significantly increased the AW, AC, and PA of UCCLP patients (P < 0.05), whereas CPW, CWA, CWAS, CWAH, PMD, and CA significantly decreased (P < 0.05). However, no significant difference was observed with the cases in group C (P < 0.05). The AW, CPW, CA, and PA of the patients in group B significantly increased compared with the cases in group A before PNAM treatment (P < 0.05). Multivariate analysis of variance indicated that TW had no statistically significant difference among the three groups (P > 0.05).

CONCLUSIONPNAM treatment is a non-surgical early treatment for the effective improvement of palatal primary deformities in UCCLP patients.

OBJECTIVETo clone the gene coding for the peptidoglycan recognition protein (PGRP) domain (PGRPd) of mouse long PGRP (mPGRP-L) and express the protein in E. coli.

METHODSThe cDNA fragment encoding PGRPd of mPGRP-L was obtained by RT-PCR from the total RNA of Balb/C mouse liver cells and cloned into pUCm-T vector. The recombinant plasmid were identified by PCR, restriction endonucleases and sequence analysis. The PGRPd gene fragment was amplified by PCR from the recombinant plasmid, inserted into pQE-30 vector and transformed into E. coli strain M15, and the expressed PGRPd protein was purified.

RESULTSA cDNA fragment of about 500 bp was amplified by RT-PCR and the recombinant plasmid, pmPGRPd, was constructed by linking the fragment to pUCm-T vector. The results of restriction mapping of the recombinant vector were consistent with those of computer analyses. Sequence analysis showed that the cloned gene fragment (518 bp) had identical sequence with the gene encoding PGRPd of mPGRP-L gene in GenBank. The recombinant expression vector pQE-PGRPd was constructed and expressed in E. coli M15. SDS-PAGE showed that the expressed product existed mainly in the lysate supernatant as a soluble protein with relative molecular mass of 29 kD.

CONCLUSIONThe PGRPd cDNA of mPGRP-L has been successfully cloned and expressed in E. coli, which provides the basis for further study of PGRP molecule.
