Objective To determine the monokine levels of serum and synovial fluid (SF) in patients with JSpAs and estimate the correlation between monokines and inflammatory indices.Methods Serum and SF monokines (IL 1?,IL 1?,IL 6,IL 8,IL 12 and TNF ?) were measured by sandwich ELISA in patients with JSpAs ( n =28) and healthy controls ( n =10).The correlation between serum monokines and inflammatory indeces and between both serum and SF monokine levels was analysed.Results Elevated serum level of IL 6 was found in patients with JSpAs as compared to healthy controls ( P

ITS2 sequence was used as a barcode to identify Viticis Fructus and its adulterants. The study collected 46 samples include Viticis Fructus and its adulterants. The sequences were obtained by extracting DNA, amplification, sequencing bi-direstionlly, and then assembling with CodonCode Aligner. To identify Viticis Fructus and its adulterants, the study used the methods of computing the genetic distances by Kimura 2-Parameter (K2P) model and constructing the Neighbor-joining (NJ) phylogenetic trees using MEGA5.0. The results showed that the maximum inter-specific K2P distance of Viticis Fructus was less than the minimum inter-specific K2P distance of Viticis Fructus and its adulterants and the NJ tree indicated that the Viticis Fructus and its adulterants could be distinguished clearly. Therefore, using ITS2 barcode can distinguished Viticis Fructus and its adulterants accurately.

A new kind of curcin (curcin 2), induced by several kinds of stresses from Jatropha curcas leaves, under the control of the 35S CaMV (cauliflower mosaic virus) promoter, was introduced into tobacco genome by Agrobacterium tumefaciens-mediated transformation method. Curcin 2 protein was only detected in the transgenic tobacco plants transformed with the cur2p fragment (coding premature curcin 2 protein), but not in the plants transformed with cur2m fragment (coding mature curcin 2 protein). The transgenic lines expressing curcin 2 showed increased tolerance to tobacco mosaic virus (TMV).

Objective To observe the MVD and integrin αvβ3 mRNA expression changes in tumor -bearing rats by using endostar combined with radiotherapy ,and to explore the potential synergy mechanism .Meth-ods We randomly divided the tumor -bearing rats into four groups:control group(NC),endostar group(ES), radiation treatment group ( RT) and endostar combined radiotherapy group ( ES +RT) .Tumor inhibition rate was calculated every other day .Microvessel density and αvβ3mRNA were texted by immunohistochemical or real time PCR in each group.Results (1)ES+RT group showed the most obvious inhibition rate;(2)Compared with NC group,microvessel density of RT was increased ,but decreased in ES group and ES +RT group significantly ( P<0.05);(3)Compared with NC group,αvβ3 mRNA expression of RT group was increased,while decreased in ES group and ES+RT group,and ES +RT group displayed a greater decrease when compared to ES group ( P<0.05).Conclusion Endostar combined radiotherapy can inhibit the growth of cancer and the expression ofαvβ3mRNA,improve the disorders of tumor vascular network .It may be one of the mechanisms of increasing radi-osensitization.

Objective To observe the immunologic effect of lactoferrin on repeated respiratory infection(IRRI) in children.Methods Ninety-eight cases of IRRI were divided into two groups randomly.The control group (48 cases)were treated with routine therapy.The treatment group(50 cases) were treated with lactoferrin based on routine therapy for 2-3 months.T cell subgroup,immunoglobulin and complements were determined before and after treatment.Results Total effective rates in treatment group and control group were 86% and 22.9% respectively.The therapeutic efficacy in treatment group was significantly higher than that in control group(P

AIM: To compare the clinical outcomes of pterygium excision followed by translocation of adjacent conjunctival autograft with stem cells or transplantation of conjunctival autograft with stem cells to treat and prevent the recurrence of pterygium.METHODS: Fifty patients (60 eyes) were divided into 2groups, and pterygium excision followed by translocation of adjacent conjunctival autograft with stem cells (group A) and pterygium excision followed by transplantation of conjunctiva autograft harvested from counter-side limbus with stem cells (group B) were performed respectively.The surgical time of each case was recorded.RESULTS: All the 50 cases (60 eyes) of pterygium were recruited. The epithelization of cornea and conjunctiva in all cases finished in 2-5d, During the follow-up of 6-12mo, pterygium reoccurred in 2 cases (1 in each group), with no difference in recurrence rate. The mean surgical time was 25± 8min for group A,43± 11min for group B, the difference being statistically significant (P<0.05, t-test).CONCLUSION: Both methods, pterygium excision followed by translocation of adjacent conjunctival autograft with stem cells or transplantation of conjunctival autograft with stem cells are effective on treating and reducing the recurrence of pterygium. Compared with the latter, pterygium excision followed by translocation of adjacent conjunctival autograft with stem cells is simpler and easier to perform, and is preferred by the patients too.

Objective To research the expression and clinical significance of SALL 4 gene in cervical cancer .Methods The ex-pression of SALL4 in 56 samples of cervical cancer and 35 samples of normal cervical tissues was detected by immunohistochemistry and RT-PCR ,and its relationship with the clinicopathological characteristics of cervical cancer was analyzed .Results The expres-sion of SALL4 mRNA was 2 .56 ± 0 .22 in cervical cancer tissues ,which was significantly higher than 0 .38 ± 0 .03 in the normal cer-vical tissues .the difference between them had statistical significance(t=58 .1 ,P<0 .01);the positive expression rate of SALL4 pro-tein was 80 .4% (45/56) in cervical cancer ,which was significantly higher than 11 .4% (4/35) in the normal cervical tissues (χ2 =41 .177 ,P<0 .01) .The positive expression of SALL4 in the cervical cancer tissues was correlated with the differentiation status of tumor ,which in the middle and high differentiation groups was lower than that in the low differentiation group (χ2 =4 .226 ,P=0 .039) ,but had no correlation with age ,International Federation of Gynecology and Obstetrics (FIGO) stage ,tumor size ,pathologi-cal type and lymph node metastasis(P>0 .05) .Conclusion SALL4 is highly expressed in the cervical cancer tissues and correlated with the tumor differentiation ,which might play an important role in the occurrence and development of cervical cancer .
