Objective To construct the eukaryotic expression vector pEGFP-N1/IL-37b and analyze the expression of IL-37 gene in THP-1 cells. Methods Total RNA was extracted from human peripheral blood mononuclear cells ( PB-MCs) and the coding region of IL-37b gene was amplified by RT-qPCR. Then, the gene was cloned into pEGFP-N1 eu-karyotic expression vector. After transfected the recombinant plasmid into THP-1 cells, the expression of IL-37 was detec-ted by RT-qPCR and Western blot. Results Double restriction enzyme digestion and gene sequencing showed that IL-37b gene was correctly inserted into the eukaryotic expression vector pEGFP-N1. RT-qPCR and Western blot showed that the IL-37 expression level was increased significantly (P<0. 01) after transfection in THP-1 cells. Conclusions We successful-ly constructed a novel anti-inflammatory cytokine IL-37 eukaryotic expression vector pEGFP-N1/IL-37b, which lays a foun-dation for further study on IL-37 functions and its association with related diseases.

·AIM: To investigate whether Erigeron Breviscapus (vant) Hand-Mazz (EBHM) EBHM has neuroprotective effect against N-methyl-D-aspartate (NMDA)-induced neuron death in retinal ganglion cell layer (RGCL).· METHODS: 60 healthy SD rats were randomly divided into four groups. 6 animals were normal control group (group A). The others were divided as group B (EBHM group), group C (normal saline+NMDA group) and group D (EBHM + NMDA group). Each group had 18 rats.10nmol NMDA was intravitreally injected to induce partial damage of the neurons in RGCL in the right eyes of Groups C and D. Same volume PBS was intravitreally injected into the left eyes as self-control. Groups B and D were pre-treated intraperitoneally with 6g/L EBHM solution at a dose of 150mg/kg body weight/day seven days before and after NMDA treatment. Group C were administrated intraperitoneally with 9g/L normal saline at the same time of EBHM injection. Rats were sacrificed at 4,7,14d after NMDA treatment. Flat whole retinas were stained with 5g/L cresyl violet and neuron counting in RGCL from both eyes were observed. Each subgroup had 6 rats.· RESULTS: There was no significant difference of neuron counting in RGCL between the right eye and the left eye in group A (P=0.200). There was no significant difference between normal control group and EBHM group either in the right eyes or in the left eyes at 4, 7 and 14 d respectively after intravitreal injection of 10nmol NMDA in group C and group D. (P=0.636, P=0.193). Neuron counting of RGCL in group C and D was significantly decreased in the NMDA-treated eyes at 4, 7 and 14d after intravitreal injection (P＜0.001). There was no significant difference between self-control eyes group and normai control group(P＞0.05). However, neuron counting was significantly higher in the EBHM+NMDA group than normal saline +NMDA group at 14days after intravitreal injection (P=0.044), but was lowered than normal control group (P＜0.05).· CONCLUSION: EBHM has no effect on neuron counting of RGCL when administered alone in normal rats.The results indicates that EBHM plays a partial protective role in NMDA-induced neuron loss in RGCL in the rats.

Objective To detect the differential gene expression between Streptococcus sobrinus(S.sobrinus) 6715 and its fluoride-resistant strains. Methods The fluoride-resistant strains of S.sobrinus 6715 was induced by increasing the concentration of fluoride step by step.Total RNA of both S.sobrinus 6715 and its fluoride-resistant strains was extracted,mRNA was separated and purificated,and then cDNA was obtained by reversed transcription.Suppression subtractive hybridization(SSH) technology was used to detect the differential gene expression between them.The differential gene expression fragments were cloned and compared with the GenBank by BLAST.Results After comparing with the GenBank by BLAST,it was identified that there were two differential gene expression fragments,fruA and SMU.438c. Conclusion The cDNA subtractive lib of differential gene expression between S.sobrinus 6715 and its fluoride-resistant strains was successfully constructed through SSH,which paves a way for the further study of fluoride-resistant mechanism.

Objective To investigate the effect of rehabilitation training on the sensory dysfunction after stroke.Methods Fifty three stroke patients with sensory dysfunction were randomly divided into 2 groups:a con- trol group and a treatment group.The control group composed of 25 patients was intervened with conventional treat- ment,while the treatment group composed of 28 patients with sensory training in addition to the conventional treat- ment.The effect of rehabilitation training of the two groups was evaluated by Fugl-Meyer Assessment (FMA) before and afer treatment.Results The FMA scores of patients of both groups increased significantly after 2 months of treatment (P

Objective To determine,the clinical significance of serum myocardial enzymes (Mb,cTNI, CK,CK-Mb,AST,LDH) in the classification of the disease severity of non-cardiogenic critically-ill patients. Compared with APACHEⅡscore concerned as the standard diagnosis of the critical ills,these biomarkers were investigated for the evaluation possibility of the degree and the prognosis of the critical ills.Method Patients admitted to our EICU were consecutively collected for the research from April to December in 2005 and the myocardial enzymes,and routine serum biochemical test and APACHEⅡscore were detected simultaneously.All the patients were classified to three groups according to the APACHEⅡscore (mild group,APACHEⅡ25) and two groups (survive group and death group) according to the prognosis.All the patients were followed up till recovery/discharge or death. Covariance,Wilcoxon and x~2 were used for the statistical analysis.Results The myocardial enzymes rose when the disease deteriorated and the APACHEⅡscore went up.AST,LDH,CK,CK-Mb,Mb were significantly different in the three groups according to the APACHEⅡscore (P

This study was aimed to explore the effect of Periplaneta Americana against alcohol-induced liver injury in mice, in order to provide a theoretical basis for the industrial production of P. Americana. Kunming mice were randomly divided into six groups, which were the normal group, model group, positive group, high-, middle-, low-dose of P. Americana groups. Intragastric administration of Tiopronin Enteric-coated Tablets 100 mg·kg-1 was given to the positive group. Intragastric administrations of whole powder of medicine were given to the high-, middle-, low-dose groups with the dosage of 6.667, 3.333, 1.667 g·kg-1, respectively. The drugs were given daily for 10 con-secutive days. After 3h of the 10th day drug administration, intragastric administration of distilled water was given to the normal group, while 14mL·kg-1 of 56℃ Red Star Liquor was given to other groups. No food was given but water for 12h. Blood was collected from the orbit. The ALT, AST and GGT in blood serum of mice were measured. The liver was dissected and liver coefficient was calculated. Histopathological examination was given on liver tissues. The results showed that compared with the normal group, the level of ALT, AST in blood serum of the model group had obvious enhanced (P< 0.01), the level of GGT had obvious enhanced (P< 0.05). Compared with the model group, the level of GGT, AST of the high-, middle-dose group had obvious enhanced (P< 0.05), the level of ALT activity had obvious enhanced (P< 0.01). There were severe liver histopathological damages in mice of the high-, middle-, low-dose group. It was concluded that P. Americana had some side effects in the treatment of alcohol-induced liver injury.

Objective To explore the eating behaviors associated with refractory functional dyspepsia (RFD).Methods In this multicenter,prospective trial,1341 new outpatients with functional dyspepsia (FD) from three Guangdong hospitals who had been diagnosed according to the Rome Ⅲ criteria were enrolled from May to September in 2012.One hundred healthy volunteers were also enrolled as controls.A questionnaire was used to obtain data,and logistic regression analysis was used for analysis.Results ①RFD was diagnosed in 24.4％ of the FD patients.②Unhealthy eating behaviors were significantly greater in patients with RFD and non-RFD than in the normal controls.Patients with RFD skipped meals more often,ate extra meals,and preferred sweets and gasproducing foods (P ＜ 0.05).③A comparison among the non-RFD subtypes,showed that those with epigastric pain syndrome had a greater preference for spicy foods (47.5 ％ vs 35.7 ％,P ＜ 0.05),and those with postprandial distress syndrome had a greater preference for sweets(50.0％ vs 36.4％,P ＜ 0.05) and gas-producing foods (14.9％ vs 7.1％,P＜0.05).Those with both subtypes skipped more meals (30.1％ vs 17.0％,P ＜ 0.05),and ate extra meals (15.0％ vs 6.5％,P＜0.05).④Logistic regression analysis showed that meal skipping(95％ CI,1.177 ～2.272; P=0.003),eating extra meals (95％ CI,1.015 ～2.604; P =0.043),and a preference for sweets (95 ％ CI,1.040 ～ 1.757 ; P =0.024) and gas-producing foods (95 ％ CI,1.022 ～ 2.306 ; P =0.039) were risk factors for RFD.Conclusion Unhealthy eating behaviors,especially,meal skipping,eating extra meals,preferring sweets and gas-producing foods correlate with RFD and these behaviors may be the key reasons for the refractory characteristic of RFD.
