AIM:To investigate the effect of different cutting centers on the visual acuity, refractive diopter and visual quality of patients undergoing laser assisted in situ keratomileusis (LASIK).METHODS: A total of 80 patients (160 eyes) with myopia treated by elective LASIK were divided into two groups.Thirty-six cases (72 eyes) with visual axis corneal reflection point (VACRP) as the cutting center were included into the VACRP group while 44 cases (88 eyes) with pupil center (PC) as the cutting center were included into the PC group.The uncorrected visual acuity (UCVA), the best corrected visual acuity (BCVA), refractive diopter, corneal aberration [total corneal and anterior corneal surface higher-order aberrations (HOA), spherical aberration (Z40), vertical coma (Z3-1), horizontal coma (totZ31) and offset of cutting centers were determined before surgery and 1mo after surgery.RESULTS: There was no difference in the probability of UCVA ≥ 0.1, BCVA and refractive diopter between the two groups at 1mo after surgery (P>0.05).The astigmatism and cutting center deviation of VACRP group were lower than those of PC group (P<0.05).The totHOA, totZ40, totZ3-1, totZ31, froHOA, froZ3-1、froZ31 and froZ40 were lower in VACRP group than PC group at 1mo after surgery (P<0.05).CONCLUSION: The UCVA of patients treated with both cutting centers for LASIK is good but VACRP has more advantages in reducing the offset of cutting center and improving postoperative visual quality.

At present,diagnostic programs of food allergy in children mainly include medical history,skin prick test,detection of serum specific immunoglobulin E (sIgE) antibody,food challenge test,and so on.Among them,skin prick test and detection of sIgE antibody are used as primary screening tests with high diagnostic sensitivity while low specificity.Additionally,double-blind placebo-controlled food challenge test is the gold standard for the diagnosis,but it is faced with a potential risk of causing systemic allergic reactions,resulting in its rare application in clinic.Moreover,basophil activation test,as an in vitro test for allergen diagnosis,has significant value in diagnosis of food allergy in children due to its high specificity and safety.Besides,basophil activation test can also be used to evaluate the severity of food allergy in children,monitor immune therapy,detect trace allergens,and so on.

There is a new research model named 'registry study/patient registry' in Western medicine, which could be referred to by Chinese medicine researchers, such as active safety surveillance. This article will introduce registry study from different aspects as the developing history, features, and application in order to inform Chinese medicine researchers of future studies.

Objective To evaluate the expression of vascular endothelial growth factor (VEGF)and endostatin (ES) in the serum of patients with differentiated thyroid cancer at the time of before and after operation and postoperative recurrence. Methods The serum samples were obtained from 7 patients with postoperative lung metastasis and 21 patients with local recurrence after operation.The serum samples from 30 normal subjects were obtained as control.The levels of serum VEGF and serum endostatin were analyzed by enzyme-linked immunosorbentassay (ELISA).Thelevelsofserumthyroglobulinwereanalyzedby Chemiluminescence method.Statistical analysis was performed with t-test using SPSS 13.0 software.Pearson correlation analysis was performed for the correlation between serum VEGF and serum ES and thyroglobulin.ResultsThe levels of serum VEGF and serum ES in patients with lung metastasis 3 weeks after operation were significantly lower than those before operation and at the time of recurrence [ VEGF:( 210.3 ± 30.4) ng/L vs (412.6 ±57.3) ng/L and(619.5 ± 126.4) ng/L,P <0.05 ;ES:(25.2 ±6.2)ng/L vs (34.3 ±7.6)ng/L and (38.6 ± 8.7) ng/L,P < 0.05 ].And the levels of serum VEGF and serum ES in patients with local regional recurrence 3 weeks after operation were significantly lower than those before operation and at the time of recurrence [ VEGF:(209.3 ±36.7) ng/L vs (399.4 ±56.3) ng/L and (406.5 ±59.2) ng/L,P <0.05;ES:(25.7 ± 4.7 ) ng/L vs ( 35.2 ± 6.8 ) ng/L and ( 31.2 ± 7.6 ) ng/L,P < 0.05 ].The expression of serum VEGF and serum ES in patients with pulmonary metastasis were significantly higher than those in patients with local regional postoperative recurrence ( P < 0.05 ).There was a linear positive correlation between serum VEGF,serum ES and thyroglobulin levels in the patient with recurrent differentiated thyroid cancer( r =0.752,0.349,P <0.01 ).Conclusion The serum VEGF and serum ES level were significantly elevated in patients with differentiated thyroid cancer before operation and recurrence.The serum VEGF and serum ES were importantindicators to reveal the biological behaviors of differentiated thyroid cancer.

Asthma is a common disease with recurrent onset which severely affects patients' quality of life.Acupuncture can improve pulmonary functions in asthma patients and thus treat this disorder.To summarize the status of acupuncture treatment for asthma,we have collected clinical literatures published in the recent 10 years and analyzed the influence of acupuncture on pulmonary functions in asthma patients from the aspects of frequently used points,needling techniques,manipulation and mechanisms to provide references for treating asthma with acupuncture.

Objective:To study the influence of Wnt5a gene silence on the proliferation,migration and invasion of lung squamous carcinoma cells.Methods:A recombinant plasmid pHI-siRNA~(Wnt5a-)was constructed and used to deliver small interference RNA (siRNA)targeting Wnt5a in SK-MES-1 cells;the transfected cells were screened to establish a stable transgenic cell line.MTT,cell cycle and Transwell assays were employed to evaluate the effect of Wnt5a gene silence on the proliferation,migration and invasion of lung squamous carcinoma cells.Results:Western blotting assay revealed that Wnt5a was lowly expressed in SK-MES-1~(Wnt5a-)(13.6%).The proliferation index(PI)of transgenic cell line was slightly lower than that of the control cell line([28.3?3.8]% vs[30.5?5.2]%). The migration and invasion capabilities of SK-MES-1~(Wnt5a-)cells were(47.3?9.2)% and(39.7?11.7)% of the control cells, respectively.Conclusion:Low Wnt5a expression can significantly inhibit the migration and invasion capabilities of SK-MES-1 cells, indicating that Wnt5a might be a potential target for gene therapy of lung squamous carcinoma.

Objective To investigate the surgical method and clinical curative results of acetabulum top compression fractures with sea gull sign. Methods Data of 14 patients who had acetabulum top compression fractures with sea gull sign were retrospectively analyzed and were accepted surgical therapy and followed up. There were 5 females and 9 males, aged from 28 to 71 years (average, 49.9 years). The pre-operative time was from 4 to 14 days (average, 9 days). Letournel-Judet fracture classifica-tion:eight cases for the anterior column+posterior semi-transverse, six cases for a simple anterior column. Three patients with lum-bar compression fracture, two patients with tibial plateau fracture, one patient with multiple rib fractures. All patients were accept-ed open reduction and bone graft and internal fixation through ilioinguinal approach or ilioinguinal approach+Kocher-Langenbeck approach. The quality of fracture reduction was assessed according to the Matta reduction criterion after operation. The hip func-tion was evaluated according to Matta. Results 14 patients were followed up from 6 to 60 months (average, 36 months). All pa-tients reached bone healing;healing time was from 3 months to 4 months (average, 3.4 months). According to the Matta reset stan-dard after operation, there were 6 excellent cases, 5 good cases, 2 fair cases, 1 poor case, the excellent and good rate was 78.5%(11/14). The Matta was from 10 to 18 scores (average, 16.4 scores), 5 excellent cases, 5 good cases, 3 fair cases, 1 poor case, the ex-cellent and good rate was 71.4%(10/14). Traumatic arthritis occurred in 3 patients. Pain was serious in two patients and disap-peared after total hip joint replacement. Pain was mild for one patient and disappeared after accepted non steroidal painkiller. One patient had heterotopic ossification after operation, which was not treatmented because of no obvious symptom. Conclusion The appropriate operation time of acetabular roof compression fracture with sea gull sign was from 5 to 10 days after fracture, which was no more than two weeks had best. Through ilioinguinal approach or ilioinguinal approach+Kocher-Langenbeck approach, the articular surface could be reduced excellent and got sufficient bone graft. The clinical efficacy was satisfactory after operation.
