Multilocus sequence typing (MLST) is a molecular genotyping method based on nucleotide sequencing. The procedure of this method characterizes isolates of bacterial species using the DNA sequencing of multiple housekeeping genes(usually seven). For each housekeeping gene, the different sequences present within a bacterial species are assigned as distinct alleles.For each isolate, the alleles at each of the loci define the allelic profile or sequence type (ST). MLST has the advantages of being robust (based on genetic data) and electronically portable to generate data that allow rapid and global comparisons between different laboratories. In this paper, the principle, method, data analysis, application, advantages and flaws of MLST are introduced.

AlM: To investigate the effect of endocapsular phacoemulsification cataract extraction and intraocular lens (lOL) implantation with a 1. 8mm or 3. 0mm clear corneal incision on total root mean square ( RMS ) value of the cornea, corneal astigmatism, spherical aberration, coma, trefoil and tear film.
METHODS:ln a prospective study, 156 age- related patients ( 196 eyes ) were randomly distributed into two groups. 1. 8mm-group comprised 94 eyes that had a silicone lOL inserted through a 1. 8mm sutureless clear corneal incision, while, 3. 0mm- group comprised 102 eyes through a 3. 0mm clear corneal incision. Postoperatively, the changes in the total RMS value of the cornea, corneal astigmatism, spherical aberration, coma, trefoil and tear film at 1wk, 1 and 3mo were determined respectively.
RESULTS:ln both groups, postoperatively at 1wk,there were statistically significant differences ( P<0. 05 ) in the total RMS value of the cornea, corneal astigmatism, spherical aberration, coma, trefoil and tear film, while, there were statistically minimal differences ( P< 0. 05 ) between 1. 8mm-group and 3. 0mm-group at 1mo, but were not statistically significantly different ( P > 0. 05 ) between two groups at 3mo postoperative.
CONCLUSlON:This study confirms that incision size has strong impact on the corneal higher-order aberrations, especially, 3. 0mm incision caused significant differences in the total RMS value of cornea, corneal astigmatism, spherical aberration, coma, trefoil and tear film compared with 1. 8mm micro-incision, therefore, micro-incision is very beneficial for clinical use in phacoemulsification.

Objective To explore the clinical features, diagnosis, and treatment of non-immunologic hydrops fetalis (NIHF). Methods The clinical data of 10 cases of NIHF in neonatal intensive case unit during January 2011 to December 2016 were analyzed retrospectively. The related literatures were reviewed. Results In 10 cases of NIHF (6 males and 4 females). the gestational age were 32-42 weeks, and the birth weight was 2.25-3.95 kg. Among them, there were 3 cases of infectious diseases (cytomegalovirus, Streptococcus agalactiae, and parvovirus infection, one case each), 2 cases of fetal cardiovascular abnormalities, 2 cases of chromosomal abnormalities, 1 case of abnormal thoracic structures, 1 case of twin transfusion syndrome, and 1 case of etiology unknown of fetal hydrops. The clinical manifestations showed that there were 8 cases with 2 or more areas of edema (or hydrops), and only 2 cases with skin edema. Finally, 6 cases were cured and discharged, 2 cases were discharged by themself, and 2 cases died. Conclusions Prenatal ultrasound is a reliable method for the diagnosis of NIHF. Fetal edema in early pregnancy, especially with congenital malformations, is recommended for termination of pregnancy. After birth, NIHF should be diagnosed promptly so as to avoid or reduce severe complications.

Objective To investigate the immunoregulatory effect of thalidomide on the peripheral blood T-iymphocytes in systemic lupus erythematosus patients in vitro. Methods T-lymphoeytes were treated by thalidomide with different concentrations, then the proliferation of these T-lymphocytes proliferation was deteted by MTT while apoptosis and lymphocyte activation marker were analyzed by flow cytometry. The mRNA expression of IL-6, IL-10 and TNF-α was measured by real-time RT-PCR, One-way ANOVA was used for statistical analysis. Results In vitro, thalidomide inhibited the expression of CD3~+CD28~+ [500 μg/ml group vs the control group, (48±9)% vs (57±9)% P<0.05]. The pro-portion of apoptotic T-lymphoeytes in the 500 μg/ml group was (36±8)%, which was significantly higher than that in the control group [(23±5)%,P<0.05 ]. The values of A_(570nm) T-lymphocytes were significantly lower in the 100 μg/ml group, 300 μg/ml groupand 500 μg/ml group compared with those of the control group ( 100 μg/ml group vs 300 μg/ml group vs 500μg/ml group vs the control group, 0.39±0.05 vs 0.34±0.04 vs 0.30±0.03 vs 0.51±0.07, P<0.05), while thalidomide promoted the expression of CD8~+CD152~+ [ 100 μg/ml group vs 500 μg/ml group vs the control group, (5.0±0.6)% vs (7.8±0.7)% vs (4.2±0.6)%, P<0.05 ]. 500 μg/ml thalidomide inhibited the mRNA expression of IL-6, 2.5~500 μg/ml thalidomide inhibited IL-10, TNF-α mRNA expression of T-lymphocytes.Conclusion Thalidomide can inhibit the proliferative activities and CD28 expression of T-lymphocytes,reduce mRNA expression of IL-6, IL-10, TNF-α, stimulate CD28 expression and apoptosis of T-lymphocytes. These effects may play an important role in it's immune-suppressive effects on systemic lupus erythematosus.
