The effect of dark tea fermentation liquid with Eurotium Cristatum on the activity of digestive enzyme was researched, as fellowing amylase, protease, lipase. The results showed that dark tea fermentation liquid with Eurotium Cristatum may increase remarkably the activity of ?-amylase and protease, but decrease efficiently the activity of lipase. The fermentation liquid improves the digestion and absorption of starch and protein, but inhibits the decomposition and absorption of fat, so it can explain the mechanism of Fu-brick tea's health functions.

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.

Objective To study the mechanism of mast cell increase in cellular leiomyoma of uterus.Methods Tissue sections from 30 cases of cellular leiomyoma of uterus,15 cases of leiomyosarcoma and 30 cases of ordinary leiomyoma were studied using immunohistochemical double labeling techniques.The expression of mast cell tryptase ahd Ki-67 as well as mast cell tryptase and chemotactic factors RANTES,Eotaxin,monocyte chemoattractant protein-1(MCP-1),transforming growth factor-? (TGF-?)were double immunostained.Results Ki-67 in mast cells was rarely expressed in each group. Expressions of regulate upon activation normal T cell expressed and secreted(RANTES),Eotaxin and TGF-? in cellular leiomyoma were 78%,89%,91%,respectively.They were all higher than those in ordinary leiomyoma and leiomyosarcoma(P

Objective To analyze the results of syphilis serology test among inpatients and to provide information for the control of syphilis.Methods Syphilis serology test results of inpatients from Jan.2010 to Nov.2012 in a tertiary general hospital were collected and retrospectively analyzed.The serum samples were screened by Treponema pallidum (TP) antibody enzyme linked immunosorbent assay (ELISA) and syphilis toluidine red unheated serum reagin test (TRUST) simultaneously.The TP-ELISA positive samples were confirmed by Treponema pallidum particle agglutination test (TPPA).Difference of measurement data was compared with analysis of variance.Results A total of 81 946 cases were collected,among which 1618 cases were positive of anti-TP.The positive rate of anti-TP was 2.27％ in the year 2010,1.58％ in 2011,and 2.11％ in 2012.For male and female patients,the positive rates of anti-TP were 2.38％ and 1.69％,respectively (x2 =48.97,P=0.00).The positive rates of anti-TP in the age groups of ≤19 years,20-39 years,40-59 years,60-79 years,and ≥80 years were 2.83％,0.94％,2.14％,2.37％,and 3.63％,respectively.The titer of TRUST was relatively lower in anti-TP positive inpatients.The anti-TP positive patients with TRUST titer ＜ 1∶8 accounted for 84.65％ in the age group of ≤19 years,79.69％ in the 20-39 years group,81.69％ in the 40-59 years group,86.12％ in the 60-79 years group,and 87.45％ in the age group of ≥80 years.The highest anti-TP positive rate (3.63％) was observed in the age group of ≥80 years with the lowest percentage (12.55 ％) of TRUST titer ≥1∶8.The lowest anti-TP positive rate (0.94％) was observed in the 20-39 years group with the highest percentage (20.31％) of TRUST titer ≥1∶8.Conclusions The characteristics of syphilis serological positivity vary depending on genders and ages.The prevention and control measures for syphilis should be strengthened,especially in the senior population.

Objective:To study the dental and skeletal changes after orthodontic treatment for malocclusion patients with rapid maxil-lary and mandibular expansion companied with fixed appliance.Methods:36 patients underwent the treatment with rapid maxillary and mandibular expansion companied with straight wire appliance.Pre-and post-treatment dental casts and lateral cephalometric radiographs were measured and compared.Results:After treatment,the maxillary and mandibular arch width perimeters increased(P <0.05).The anterior arch depths decreased(P <0.05).No significant differences were found in vertical skeletal variables(P >0.05).U1-SN and U1-NA decreased,L1-MP and L1-NB increased(P <0.05).Conclusion:Dental crowding can be solved effectively and occlusion re-lationship can be kept well with rapid maxillary and mandibular expansion companied with straight wire appliance without influence on the vertical skeletal relationship.

Objective:To evaluate the effects of maxillary protraction with or without rapid maxillary expansion in the treatment of Class Ⅲ malocclusion by Meta-Analysis.Methods:The randomized controlled trail,quasi-randomized controlled trail and the clinical controlled trail about the treatment of Class Ⅲ malocclusion by protraction with or without expansion were searched in the database of Cochrane Library,Embase,PubMed,Medline,CBM,Wan Fang,CNKI,VIP.2 authors qualified and extracted the data independently.Then the Meta-analysis was performed by using the RevMan 5.3 software.Results:7 studies with 228 cases were included,114 cases were treated by maxillary protraction with expansion and the other 114 cases by maxillary protraction without expansion.The Meta-analysis showed that:there was no significant difference in SNA,SNB,ANB and SN-PP except ANS-Me,U1-NA,SN-MP.A favorable improvement of the sagittal relationship between maxillary and mandibular was observed by using protraction whether with expansion or not.The expansion did not shorten the course of treatment,but it lowered the inclination of upper incisors,resulting in more clockwise rotation of mandibular plane and increase of the facial vertical dimension.Conclusion:Maxillary protraction with rapid maxillary expansion can be used in the treatment of class Ⅲ malocclusion with incisor labioclination.
