Objective To study the protective effect of recombination human erythropoietin (rhEPO) on the apoptosis of retinal neurons induced by glutamate.Methods The primary retinal neurons of postnatal SD rats were cultured in vitro for 7 days and divided into 3 groups :control group ,glutamate group and rhEPO pretreatment group.The neurons in the rhEPO pre-treatment group were afterwards allocated to three subgroups in terms of different rhEPO treatments (0.15 ,0.30 or 0.50 U/mL rhEPO for 12 h).Those in glutamate group and rhEPO pretreatment group were treated with glutamate at the concentration of 20μmol/L for 30 min for establishment of the apoptosis model.Twenty-four h later ,the apoptosis index (AI) was assayed by TUNEL and the expressions of BCL-xL mRNA and protein was detected by RT-PCR and immunocytochemistry respective-ly.Results The AI was significantly higher in the glutamate group than in the control group (P<0.01).The AI was signifi-cantly reduced ,and the expression level of BCL-xL mRNA and protein was markedly dose-dependently increased in the rhEPO pretreatment groups compared with the glutamate group (P<0.01).Conclusion The rhEPO pretreatment can inhibit the glu-tamate-induced apoptosis of retinal neurons by up-regulating the expression of BCL-xL .

AIM:To evaluate changes in tear film stability and meibomian gland function and the clinic efficacy of three different artificial tears in patients with preoperative dry eye after phacoemulsification.METHODS:All 90 cataract patients (90 eyes) with preoperative dry eye who underwent phacoemulsification randomly divided into three groups (Group A treated with protein-free calf blood extract ophthalmic gel;Group B treated with sodium hyaluronate eye drops;Group C treated with Vitamin A palmitate eye gel).Ocular Surface Disease Index (OSDI), Schimer's I test(SⅠt), tear film break time (BUT), corneal fluorescein staining (FL) and meibography were performed for all patients preoperatively and 7, 30 and 90d postoperatively.RESULTS:No statistical differences existed among the three preoperative groups (P>0.05).Except meibomian gland score, there was no statistical significance among preoperatively and 7, 30, 90d postoperatively of the three groups (P>0.05).At 7d postoperatively, SⅠt and BUT of every group were lower than those before treatment, FL scores and OSDI scores were higher than those preoperative (P<0.05);there were no statistical differences among the three groups(P>0.05).At 30d postoperatively, SIt, BUT, OSDI scores in group A and C were better than in group B, which displayed statistical differences (P<0.05);FL scores in group A were significantly better than in group B and C (P<0.05).At 30, 90d postoperatively, SIt, BUT, FL scores, OSDI scores were better than preoperative results, which displayed statistical differences (P<0.05).There were no statistical differences among the three groups at 90d postoperatively (P>0.05).CONCLUSION:Tear film stability and meibomian gland function were affected by phacoemulsification.Topical application of deproteinised calf blood extract eye gel, sodium hyaluronate eye drops and Vitamin A palmitate eye gel all hase a clearly beneficial effect on subjective symptoms.Deproteinised calf blood extract eye gel and Vitamin A Palmitate Eye Gel had more powerful effect on BUT than sodium hyaluronate, however deproteinised calf blood extract eye gel is more effective in superficial punctuate keratopathy.

With GC-MS、LC-UV and gene analysis,we studied Pseudonomas sp.W2 metabolic pathway of bisphenol A(Bpa).It was discovered that 4'-(trimethylsiloxy)-Acetophenone、p-Hydroxy benzaldehyde and p-Hydroxy benzoic acid are medium metabolites and that the bacteria has pcaG.

Luteinized unruptured follicle syndrome (LUFS), a specific type of ovulation disorder, is for a cause of female infertility. Acupuncture therapy has a good effect for LUFS. In order to understand the clinical effects and research situation of acupuncture therapy for LUFS, the author analyzed and reviewed the relevant literature. It was indicated by the findings that acupuncture therapy and integrative therapy of acupuncture and Chinese herbs have good therapeutic effect for this disease. Acupuncture therapy has the effect to promote ovulation. By the therapeutic principle to tonify the kidney and circulate blood, acupuncture therapy mostly was adopted in the period of ovulation. The acupoints are mostly selected from the lower abdomen and lower limbs, possibly based upon syndrome differentiation at the same time. The needling techniques are of certain characteristics. But, the issues of low quality, un-standardized inclusive, exclusive criteria and effective criteria still exist in the current clinical study.

0.1), but duration of sensory and motor block in S group was longer than that in C group (P

Objective To investigate the clinical and intellectual characteristics of children with cerebral palsy of ataxia type.Methods Twenty-one children with cerebral palsy of ataxia type were evaluated by the illness history,clinical physical examination,brain MRI scan and intellectual assessment.Results Delayed motor milestones and dysfunction of balance were found in these children,and 80.9% of brain MRI scan was abnormal as cerebellar damage,and delayed intellectual ability found in these children was ameliorated as improvement of motor function.Conclusion Cerebral palsy of ataxia type is mainly caused by cerebellar damage manifests as delayed motor function,dysfunction of balance and mental retardation.

Corneal endothelial cell(CEC)is the most critical part for the cornea, of which activity can influence the postoperative vision.It is very important for the clinical cornea preservation considering the function and its self-purification of donor cornea.There are a variety of classical methods, which can significantly prolong the saving time of donor cornea with its good quality of CEC.We reviewed the published papers about present preservation methods of cornea, which can give us many suggestions for the clinical cornea preservation.

Objective: It was to investigate the content alteration of the tannins in cibot rhizome and its processed samples. Method: The casein method was used to determine the content of tannins. Results: The content of tannins decreased after the medicinal material was processed. Conclusion: Processing may decrease the content of tannins in cibot rhizome. The raw was better than the other processed samples if the tannins were used as active constituents.

ObjectiveTo investigate the role of signal transduction of TLRs in the Henoch-Schonlein purpura (HSP). Methods Reverse-transcription PCR (RT-PCR) and real-time PCR were used to evaluate the levels of TLRs(1～10), MyD88, TRAF6, TRIF, IFN-α, IFN-β, IL-6, IL-1β, TNF-α, IP-10, RANTES,iNOS, Blys/April mRNA expression in peripheral blood mononuclear cells and their expression levels were compared using t test., while the concentration of plasma cytokines such as Blys、IFN-α、IFN-β、IL-6、IL-1、TNF-α was measured by enzyme-linked immunosorbent assay(ELISA).Expression levels of those genes were compared using t test. Results①Compared with the control group, the expression levels of TLR1, TLR2,TLR6, TLR5, TLR3, TLR7, TLR9 mRNA were up-regulated significantly(P＜0.01), while no difference of TLR4 was detected (P＞0.05).②Transcription levels of MyDg8(2.47±1.06) vs(0.73±0.22), TRAF6 (2.54±0.72)×10-3vs(0.70±0.20)×10-3, TRIF(3.18±0.86)×10-3vs(0.93±0.35)×10-3 were significantly up-regulated in acute phase of HSP (P＜0.01).③The levels of IFN-α and IFN-β protein and mRNA were remarkable increased (P＜0.01).④ The expression of cytokine/chemotactic factor such as IL-6, IL-1β, IP-10, RANTES,iNOS was higher than that of the control group(p＜0.01), while TNF-αdid not change in children with HSP (P＞0.05). ⑤ It was detected that the expression of Blys/April was higher than that of the control group(P＜0.01). ConclusionExpressions of TLR1, TLR2, TLR6, TIR5, TLR3, TLR7, TLR9, MyD88, TRAF6, and TRIF are up-regulated during acute phase of HSP, suggesting that aberrant activation of TLRs triggered by microbes may be one of the initiating factors of immune aberrance in HSP. Over expression of cytokine/chemotactic factor or Blys/April owning to the aberrant activation of TLRs, may be correlated with immunological pathogenesis of HSP.
