Objective To investigate the mRNA expression of CC Chemokines, including RANTES (regulated upon activation, normal T cell expressed and secreted), monocyte chemoattracctant protein-1 (MCP-1), monocyte chemoattracctant protein-3 (MCP-3) and macrophage inhibitory protein 1? (MIP-1?), in peripheral blood mononuclear cells (PBMCs) of patients with chronic urticaria, their mutual correlation, and the relationship between the expression level of CC chemokines and the serum level of IgE and eosinophil cationic protein (ECP) in the patients. Methods Reverse transcription-polymerase reaction (RT-PCR) was applied to semiquantitatively analyze the mRNA expression of RANTES, MCP-1, MCP-3 and MIP-1? in PBMCs from 31 patients with chronic urticaria and 22 healthy subjects. Results The mRNA expression of RANTES, MCP-1, MCP-3 and MIP-1?was significantly higher in the patients than those in the normal controls (P 0.05). In the patients, the mRNA expression of RANTES negatively correlated with the serum level of IgE and ECP (P

Objective To explore the difference of DISC1 gene polymorphism between schizophrenia patients and normal subjects,as well as the association of gene polymorphism with mRNA expression.methods 40 schizophrenia patients and 40 normal subjects were recruited randomly from southern region of Fujian,China.DISC1 mRNA level was assessed by RT-PCR and the genotype was evaluated by sequencing with the amplified PCR products from peripheral blood DNA.Result srs6675281 locus only found CC type,other types were not found.According to the genotyping Result ,the rs821616 locus has AA,AT and TT three types,but the genotype and allele frequency between the two groups were not significantly different (Genotype:x2=0.923,P=0.63;Allele:A>T,x2=0.656,P=0.418).As far as rs11122319 locus,AA,AG and GG three types were found in this study,there was no significant difference between patients and normal controls (Genotype:x2=3.922,P=0.141;Allele:A>G,x2=0.184,P=0.668).Subjects were divided into AA,AG,GG three types based on rs1417584 locus genotyping,however the genotypes and alleles of this locus between the two groups were significant difference (Genotype:x2=6.631,P=0.042;Allele:A>G,x2=4.592,P=0.032),and the DISC1 mRNA expression that corresponding to the genotype AG in patients and normal subjects was significantly different (t=3.916,P=0.004).Conclusion Based on these findings,rs1417584 locus may be implicated the expression and regulation of DISC1 gene,may be a pathogenic factor of schizophrenia and the genotype AG may be corresponding to a higher risk.

Objective To explore the effects of berberine(BBR)on the prevention of left ventricular remodeling after acute myocardial infarction(AMI)in New Zealand rabbits.Methods AMI were conducted by ligating left coronary artery in female New Zealand rabbits.Five days after the procedure,the 28 survival rabbits were randomized into the controls(n=14)or BBR treatment group [n=14,BBR 8 mg/(kg?d)iv.].Hemodynamic studies were performed 4 weeks after the completion of treatment.Pathology study of the rabbits hearts was carried ont and matrix metalloproteinases(MMPs)2 and 9 were detected by immunohistochemical analysis in the non-infarct myocardium.Results Compared with the control group,left ventricular relative weight(LVRW)and LV end diastolic pressure(LVEDP)were decreased in the treatment group 4 weeks after BBR intervention(1.55?0.12 vs 1.69?0.13,P

Objective To investigate the characteristics of optical coherence tomography (OCT) in eyes with repaired idiopathic macular hole (IMH) after operation and the relation with recovery of visual acuity. Methods The characteristics of OCT images of 24 patients (25 eyes) with repaired IMH after vitrectomy,internal limiting membrane(ILM)peeling and auto-serum healing were analyzed retrospectively. In the patients with IMH, the macular hole was found in 9 eyes at stage Ⅱ, 13 eyes at stage Ⅲ, and 3 eyes at stage Ⅳ. Examinations of best-corrected visual acuity, slit-lamp biomicroscopy with fundus contact lens, fundus photography, fundus fluorescein angiography(FFA) and OCT were performed on the patients 3 to 24 months after surgery. Results OCT images of the repaired IMH were categorized into 3 patterns: U-type (5 eyes) with relative normal foveal contour; V-type (7 eyes) with steep foveal contour;W-type (13 eyes) with foveal defect of neurosensory retina, but without warped hem of retinal hole or cystic formation. Postoperative visual acuities were improved in all of the patients and the best ones were in group U-type. Conclusion Characteristics of OCT images of repaired IMH may be related to the postoperative visual acuity.

Objective To assess the efficacy of almitrine and raubasine (Duxil) on post stroke rehabilitation Methods A clinical trial was done with a randomized, double blind, placebo controlled method Patients with ischemic stroke were included as having 1 month after the acute onset and receiving randomized treatment of either Duxil or placebo 2 tablets daily for 3 months The patients were assessed by using Barthel Index (BI), neurological functional deficit scores (NFDS), and Hasagawa dementia scales (HDS) each month after giving treatment Results In this study, only 74 cases were observed Of them, 38 patients received Duxil and 36 patients received placebo The baseline characteristics were compared between both groups Duxil was significantly shown more effective than placebo by increasing BI at 1, 2 or 3 months and by reducing NFDS at 1 month after treatment, more Duxil treated patients' NFDS had improved as compared with placebo treated patients In comparing with the pre treatment condition, there appeared a strong tendency of improvement in HDS with Duxil, although this significance was not confirmed by the difference of scores between two groups More Duxil treated patients than placebo controlled patients were reported having adverse events, but the difference was not significant at the 5% level All these events were mild, of short duration and resolved without treatment Conclusion Duxil can accelerate the recovery of nervous function to some degrees after stroke

Objective To evaluate the therapeutic effects and side effects of MMF on severe SLE patients compared with CTX.Method All 106 severe SLE patients were randomly allocated to 2 groups:MMF treatment group (53 patients):1 5 g/d for 3 months,1 0 g/d for following 3 months,and then 0 5～0 75 g/d;IVCTX treatment group:0 75 g/m 2 per month for 6～12 months.Prednisone was used in all patients.Clinical and laboratory parameters including SLE DAI,Hb,platelet,urine protein,albumin,SCr,aCL,ANA and anti dsDNA were observed.Results After 3 month treatment,all clinical and laboratory parameters were significantly improved in MMF group,while only partial parameters were improved in CTX group.Hb and platelet increased and urine protein and anti dsDNA decreased faster in MMF group than in CTX group.At month 6 the clinical and laboratory parameters improved significantly in both groups ( P

Objective To explore the effect of CYP2D6 gene polymorphism on blood concentration,therapeutic efficacy and adverse effects of anti-depression drug venlafaxine.Methods 69 cases of patients with depression were selected randomly from southern region of FuJian,China.The blood concentration of venlafaxine was detected by HPLC,and the CYP2D6 genotype was determined by sequencing with the amplified PCR products from peripheral blood DNA.The therapeutic efficacy and adverse effects of venlafaxine were evaluated by Hamilton depression scale(HAMD) and treatment emergent symptom scale(TESS) respectively.Results Subjects was divided into CC,CT,TT three groups based on rs16947 locus genotyping.The blood concentrations of venlafaxine were (157.35±15.63) ng/ml,(70.17±5.11) ng/ml,(115.72± 10.2) ng/ml respectively and there was no significant difference (F=1.257,P=0.301).The dose-corrected concentrations and normalized concentrations were not significantly different (F=1.683,1.547,P＞ 0.05).Similarly,the reduction rate of HAMD (CC:(40.6 ± 7.23) ％,CT:(51.7±7.09)％,TT:(42.8±14.1)％) and TESS scores (CC:1.3±0.21,CT:1.3±0.36,TT:1.2±0.28) were not significantly different either (P＞0.05).In 69 samples in this study,genotyping of rs3892097 locus only found GG type,and no further examination was performed.Genotyping divided rs1065852 locus into CC,CT,TT three groups.The blood concentrations of venlafaxine were (42.87±9.9) ng/ml,(64.25 ± 13.59) ng/ml,(181.56± 14.15) ng/ml respectively,and there was significant difference among the three groups (F=4.893,P=0.016).The dose-corrected concentrations and normalized concentrations were also significantly different (F=3.985,3.648,P＜0.05).The reduction rate of HAMD (CC:(42.6±8.23) ％,CT:(48.8± 10.8) ％,TT:(63.4±9.15) ％) was not significantly different (F=2.961,P=0.07).The difference of TESS scores was similar to that of HAMD reduction rate.Conclusion Among the 3 loci studied,only rs1065852 locus within CYP2D6 gene can affect its enzyme activity and then influence the therapeutic efficacy and adverse effects of venlafaxine.

Crohn's disease (CD) is a chronic nonspecific inflammatory disease.CD can affect any location in the digestive tract,and it also affect other organs,including the eyes,skin,liver and joints,which are termed extraintestinal manifestations (EIMs).The cutaneous manifestations of CD are common and occur in about one-third of patients.EIMs of CD have been divided into 3 categories.(1) Specific lesion,cutaneous manifestations of CD were the same as histopathologic findings of underlying gastrointestinal lesion.(2) Reactive lesion,it was also inflammatory lesion which was usually accompanied by underlying gastrointestinal disease while inflammatory injury was different from histopathologic findings of gastrointestinal lesion.(3) Associated lesion,it was caused by sequelae of human leucocyte antigen and chronic inflammation.In the current era of ever-expanding therapeutic options for CD,some investigators have proposed a fourth category of EIMs,namely those that are therapy-related lesion.The therapy-related lesion is closely related to disease-associated conditions in light of certain skin findings,and there is potential overlap between them.

OBJECTIVE:To analysis the distribution and antibiotic resistance of common isolated pathogenic bacteria in urinary-tract infection cases in our hospital so as to provide scientific basis for the rational clinical use of antibacterials.MET-HODS:625 urine samples were collected from urinary-tract infection cases in our hospital in 2006,from which,344 strains of bacteria were isolated,which were cultured and subjected to drug sensitivity test.RESULTS:Of the 344 strains of bacteria,Gram-negative bacilli took the lead,accounting for 60.2% of the total,followed by Gram-positive cocci(33.4%) and fungi(6.4%).The detection rates of ESBLs-producing Escherichia coli.and Klebsiella pneumoniae were 49.2% and 27.3%,respectively.The bacteria had different resistant rate to different antibiotics and were multidrug resistant.CONCLUSION:Bacterial culture of urine and drug-sensitivity test should be performed promptly and drugs should be used with prudence for urinary infection cases to reduce drug-resistance bacteria.

Objective To analyse the clinicopathological characteristics of synovial sarcoma (SS) from histomorphology,immunohistochemical (IHC) and fluorescence in situ hybridization (FISH),and to investigate the related factors influencing the prognosis of SS patients.Methods 94 cases were collected,including 60 SS cases and 34 in dined to SS cases.The expressions of common antibodies related to the diagnosis of SS Vimentin,CD99,AE1/AE3,EMA,CD34,Calponin,Ki-67 were detected by IHC,and the SYT-SSX fusion gene was detected by FISH.The clinical pathologic factors that affecting the prognosis of patients were analyzed through the statistical method.Results The positive rates of Vimentin,CD99,AE1/AE3,EMA,CD34,Calponin,Ki-67 were 100.00 ％,74.47 ％,36.17 ％,28.72 ％,17.02 ％,90.43 ％ and 60.64 ％ respectively.FISH results showed that 81 patients were tested with SYT gene translocation,including 54 cases who were considered as SS,and 27 cases who were suspected/inclined to SS,and the number of positive cells surpassed 80 ％.The gene translocation was not related with the patient' s age,sex,tumor position,histological type,differentiation of the cancer (all P ＞ 0.05).Single factor survival analysis showed that the degree of differentiation,tumor diameter,the recurrence and metastasis had certain influences on patients' survival time (all P ＜ 0.05).Multiple factors regression analysis showed that the degree of differentiation and tumor diameter were the risk factors influencing the prognosis of SS (risk coefficients ＞ 1,P ＜ 0.05).Conclusions IHC combined with FISH SYT-SSX fusion gene detection have the vital significance in the diagnosis of SS.The degree of differentiation and tumor size are the risk factors influencing the prognosis of SS.
