Abstract? AlM: To study the effect of pterygium excision combined with limbal stem cell on visual acuity and refractive status.?METHODS:A total of 120 cases ( 178 eyes ) pterygium cases were enrolled in our hospital from March 2012 to May 2014 and divided into observation group ( 60 cases, 90 eyes) and control group (60 cases, 88 eyes) according to different treatment methods. Patients in observation group received pterygium excision combined with limbal stem cell transplantation, those in control group received pterygium excision. Vision levels, astigmatism degrees were compared. The effects of age, working environment and medial rectus muscle insertion distance from corneal limbus on postoperative visual acuity were analyzed.? RESULTS: Before operation, acuity levels and astigmatism degrees of two groups had no difference ( P>0. 05 ); 1, 2 , 3, 4wk after operation, visual acuity in observation group were higher than that in control group (0.49±0.09 vs 0.34±0.07, 0.76±0.11 vs 0.42±0.04, 0.95± 0. 14 vs 0. 59±0. 08, 1. 09±0. 18 vs 0. 74±0. 10), astigmatism degrees were lower than that in control group (0. 96±0. 12 vs 1. 85±0. 28, 0. 68±0. 08 vs 1. 51±0. 23, 0. 54±0. 08 vs 1. 23± 0.19,0.42±0.07 vs 0.91±0.14); visual acuity of patients older than 45 years old, indoor work, medial rectus muscle insertion distance from corneal limbus 3-5 mm were higher, astigmatism degrees were lower.?CONCLUSlON:Pterygium excision combined with limbal stem cell transplantation is helpful to improve visual acuity and astigmatism degree; recovery of visual acuity is affected by age, working environment and medial rectus muscle insertion distance from corneal limbus.

OBJECTIVE:
To study ApoB gene genetic polymorphism of Han nationality and Mongolian nationality in midwest area of Inner Mongolia.
METHODS:
Some unrelated individuals of Han nationality and Mongolian nationality in midwest area of Inner Mongolia were selected. Polymerase chain reaction-restriction fragment length polymorphism technology was used to check the presence of Xba I (X+) and EcoR I (E-) sites of rare alleles. The genotype frequency, allelic frequency and population genetics parameters were calculated.
RESULTS:
The frequencies of Xba I (X+) and EcoR I (E-) rare alleles were 2% and 4.6% in Han population. There was no Xba I (X+) or EcoR I (E-) rare alleles found in Mongolian nationality.
CONCLUSION
The allelic frequencies of ApoB gene Xba I and EcoR I sites are very different in different races. These sites may be used in identification of ethnicity.

OBJECTIVETo observe the effects of Mongolian pharmaceutical Betel shisanwei ingredients pill on AC-cAMP-PKA signal transduction pathways in hippocampus and prefrontal cortex of depressive rats.
METHODSixty male Wistar rats were randomly divided into six groups according to the sugar consumption test (10 rats in each group), normal control group,model group,fluoxetine group (3.3 mg x kg(-1)) and low dose, medium dose and high dose group (0.25, 0.5, 1 g x kg(-1)) of Betel shisanwei ingredients pill. Except the normal control,the other groups were treated with the chronic unpredictable mild stress stimulation combined with lonely raising for 28 days. 10 mL x kg(-1) of drugs were given to each rat once daily,continuously for 28 days. The AC activity of the hippocampus and prefrontal cortex were determined by radiation immunity analysis (RIA), while cAMP and PKA quantity were determinated by Enzyme-linked immunosorbent (ELISA).
RESULTThe AC activity, cAMP and PKA quantity of hippocampus and prefrontal of mouse model of Chronic stress depression decreased significantly than those of control group (P < 0.05 or P < 0.01). However, the AC activity, cAMP and PKA quantity of rat hippocampus and prefrontal cortex in the fluoxetine group and the Mongolian pharmaceutical Betel shisanwei ingredients pill group indecreased significantly than those of model group (P < 0.01 or P < 0.05). Especially for the high dose group of Mongolian pharmaceutical Betel shisanwei ingredients pill.
CONCLUSIONThe AC-cAMP-PKA signal transduction pathways in hippocampus and prefrontal cortex of depression model of rats is down-regulated, whereas Mongolian pharmaceutical Betel shisanwei ingredients pill could up-regulated it to resist depression.

AIM:To evaluate the efficacy and safety of "one-stitch anastomosis through the skin" repair of canalicular laceration.METHODS:The data of 32 cases (32 eyes) of canalicular laceration who underwent repair of lacerated canaliculi with one-stitch anastomosis through the skin were retrospectively reviewed, inferior canalicular laceration in 29 patients,superior canalicular laceration in 1 patient, 2 cases involving both the inferior and superior canalicular laceration. All the operations were performed under surgical microscope, 5-0 silk sutures were used and silicone tube of 0.8mm diameter was employed in intubation. The stents were left in place for 3 months postoperatively and then removed. The follow-up period was 1 to 36 months.RESULTS: In 32 patients, 28 (88%)patients were cured entirely, 3 (9%)patients were meliorated, and 1 (3%)patient had no effects. A total of 29 patients complied with scheduled follow up 1-36 months (average 12 months) after stent removal, and 3 patients were lost in follow-up. All the patients had got good recovery of eyelid laceration with no traumatic deformity in eyelid and canthus.CONCLUSION: In "one-stitch anastomosis through the skin"repair of canalicular laceration, the cut ends could be anastomosed directly,for there was no suture remained in the wound permanently, so there was no suture-related granuloma which might cause obstruction or stenosis of canaliculi. It was simple, economical ,effective and safe.
