Objective To investigate the regulatory effect of miR-21 on ADAMTS-1 expression in pulmonary fibrosis model. Methods A mouse model of pulmonary fibrosis was established using bleomycin (BLM) anda model of pulmonary fibrosis was constructed in vitro , the expression level of miR-21 was measured by quantitative real-time polymerase chain reaction (qRT-PCR), while the protein expression of ADAMTS-1 was measured by Western blot. NIH3T3 were transfected with miR-21 mimics and inhibitor in vitro and the cellular expression of ADAMTS-1 was measured by Western blot. Results Compared with the blank group , in mouse models of pulmonary fibrosis , the miR-21 expressions in lung tissues at three time points after BLM-treatment were significantly up-regulated while an evident decrease in ADAMTS-1 expressions were observed (P < 0.01). In vitro pulmonary fibrosis model , NIH3T3 cells after TGF-β1 in concentration 5 μg/L stimulation down-regulated ADAMTS-1 expression and up-regulated miR-21 expression (P < 0.01). NIH3T3 transfected with miR-21 mimics and inhibitor, up-regulated miR-21 expression, while down-regulated ADAMTS-1 protein expression. Conclusions Up-regulation of miR-21 and Down-regulation of ADAMTS-1 might be involved in the progression of pulmonary fibrosis model; miR-21 could negatively regulate ADAMTS-1 expression.

Objective To investigate the role of long noncoding RNA-AJ227913 in the pathogenesis of primary gout arthritis (GA). Methods The subjects were divided into three groups:30 acute gout patients (AGA), 30 non-acute gout patients (NAGA), 30 healthy controlsand 30 hyperuricemia patients (HUA). Real-time quantitative polymerase chain reaction (RT-qPCR) was employed to examine the expression of AJ227913 in peripheral blood mononuclear cells(PBMCs) from four groups. 100 μg/ml monosodium urate (MSU) was used to stimulate the peripheral blood of NAGA and healthy controls patients. Then the expression ofAJ227913 was detected by RT-qPCR. Kruskal-Wallis test, Mann-Whitney test, Spearman correlations were used for statistical analysis. Results The expression level of AJ227913 in the AGA group (0.0557 ±0.0156) was higher than that in the NAGA group (0.0223±0.018) and healthy controls group (0.0038±0.0013). There was significant difference between the NAGA group and healthy controls group (P>0.05). Compared with the control group, the expression of AJ227913 in NAGA group which were stimulated by MSU was significantly increased. The Spearman correlation analysis found that the AJ227913 expression levels in GA groups were correlated with UREA (r=0.608, P<0.01), CREA (r=0.337, P<0.05), CYSC (r=0.422, P<0.01). Conclusion Altered expression of AJ227913 may be involved in the inflammatory process of GA and the balance of uricacid.

OBJECTIVETo compare postoperative blood loss under different negative pressures of drainage after total hip arthroplasty for the treatment of femoral neck fractures.

METHODSFrom January 1st to December 30th 2013, 74 patients with femoral neck fractures treated with total hip arthroplasty were randomly divided into two groups: high negative pressure drainage group and low negative pressure drainage group. In high negative pressure drainage group, there were 34 cases including 10 males and 24 females, with a mean age of (75.94 ± 9.02) years old, and the patients were treated with 60 kPa negative pressure of drainage. In the low negative pressure drainage group, there were 40 cases including 13 males and 27 females, with an average age of (74.93 ± 8.90) years old, and the patients were treated with 30 kPa negative pressure of drainage. The amount of total drainage, total blood loss, and hemoglobin change were compared between these two groups.

RESULTSAll the patients got primary healing without infections. In high negative pressure drainage group,the change of hemoglobin was (41.74 ± 15.69) g/L, total blood loss was (1,217.73 ± 459.50) ml and the drainage volume was (312.94 ± 103.44) ml; while in low negative pressure drainage group,the results were (34.90 ± 12.90) g/L, (904.01 ± 381.58) ml and (129.25 ± 44.25) ml separately. All the results in high negative pressure drainage group were higher than those in the other group. Three days after operation, the change of hemoglobin was (46.00 ± 13.29) g/L and total blood loss was (1,304.72 ± 421.75) ml; while in low negative pressure drainage group, the changes of hemoglobin was (43.87 ± 11.39) g/L and total blood loss was (1,196.78 ± 344.20) ml; there were no statistically significant differences between two groups.

CONCLUSIONWhen placing drainage devices after total hip arthroplasty for the treatment of femoral neck fractures, the level of negative pressure should be chosen according to preoperative level of hemoglobin and HCT in patients. For old patients with femoral neck fracture, low negative pressure is more suitable.

Objective To summarize the clinical experience of three different treatments for gallbladder and common bile duct stones.Methods The clinical data of 180 cases of gallbladder stones combined with bile duct stones undergoing surgery from May 2010 to May 2013 were retrospectively analyzed.They were divided into three groups,A group of 60 patients underwent a period of endoscopic sphincterotomy (EST),under the second phase of laparoscopic cholecystectomy (LC);Group B 60 patients underwent laparoscopic cholecystectomy (LC) + laparoscopic common bile duct exploration surgery (LCBDE) + T tube drainage;Group C 60 patients underwent conventional open cholecystectomy (OC) + bile duct exploration (OCBDE) + T tube drainage.Results A group of 53 cases completed surgery successfully,5 cases of remaining 7 patients failured in the first phase surgery,2 cases of the 5 patients did LC + LCBDE,3 of the 5 patients underwent conventional surgery.Two patients underwent the conventional surgery in the second phase surgery.B group of 57 cases completed surgery successfully,three cases convert to open surgery.All of the group C completed the surgery successfully.Group A complication was the most in the three groups (P＜0.05);group B had the shortest time of hospitalization (P＜0.05),the complication rate was lower than that in group A (P＜0.05),the complication had no significant difference between A and B.(P and group B ＞ 0.05),group B had shortest operation time (P＜0.05);no statistically significant differences were found among three groups in fasting time.Conclusion Three treatment methods have advantages as well as disadvantages,a reasonable treatment should be selected according to the specific circumstances.

Objective To observed the immigration and proliferation of Schwann cells in acellular xe- no-nerve graft in rats.Methods The sciatic nerves on the right side of the rats were exposc.d and 0.8cm long segments of the nerves were removed from the mid-thigh level and replaced by 1.0cm long rabbit nerves made acellular through chemical extraction.After 4 months,the immigration and proliferation of Schwann cells in the graft were revealed by HE staining,S-100 immunohistochemieal staining and transmission electromicro- scope.Results In the rats repaired by acellular nerves,regenerated axons upgrow into the graft,and a- round regenerated axons there were abundant cells aligned,the cytoplasm of which were S-100 immunoreac- tive.Electromicroscope observing showed that regenerated axons were surrounded by myelin formed by the mi- grated cells reoccupied the acellular segments.Conclusion The host Schwann cells can immigrate into rab- bit nerve grafts made acellular through chemical extraction and form myelin enwrapping regenerated axons in rats.

Objective To explore the dynamic changes of soluble interleukin-2 receptor(SIL-2R) and tumor necrosis factor ?(TNF-?) levels in pediatric malignant solid tumors clinical value.Methods The levels of SIL-2R and tumor necrosis factor ?(TNF-?) were measured by ELISA in 15 cases with pediatric malignant solid tumors before and after chemotherapy.Results Before chemotherapy the levels of SIL-2R and TNF-? of every group patients were significantly higher those that of normal control group (P

Objective To investigate whether erythropoietin(Epo) is potentially beneficial in protecting cultured retinal neurocytes.Methods Primary isolated retinal nerve cells were cultured.Expressions of Epo and EpoR protein in cultured retinal neurocytes were decected by immunohistochemical analysis.Survival of cultured neurocytes that were incubated in the presence of Epo or glutamate in the presence or absence of Epo were estimated by determining the activity of their mitochondrial dehydrogenases using the MTT assay.Results Epo and EpoR protein were expressed on the cultured retinal neurocytes.The presence of different concentrations of Epo did not improve the survival of retinal neurocytes,and Epo could prevent glutamateinduced toxicity. Conclusion Epo is beneficial in protecting mixed cultured retinal neurocytes from glutamate-induced cytotoxicity.

OBJECTIVETo evaluate the clinical characteristics and long-term outcome of 310 cases of thymectomy for myasthenia Gravis.

METHODSThe data of 310 patients with thymectomy were analyzed retrospectively to study the patient selection, operative techniques, perioperative management and results for myasthenia Gravis. Absolute and relative scores for clinical evaluation were used as the criteria to determine the therapeutic effects of thymectomy.

This study is to investigate the effect and mechanism of puerarin on DNA damage of HaCaT cells induced by UVB. Puerarin pre-treated cells were irradiated with UVB at 30 mJ x cm(-2). Twenty four hours after irradiation, DNA damage was detected by comet assay, ceramide was measured by thin layer chromatography and gas chromatography, intracellular free calcium ion was analyzed by flow cytometry, the phosphorylation level of p38 protein was examined by Western blotting method. Levels of DNA damage, ceramide, free calcium ion and p-p38 protein were elevated in UVB model cells. Contrary to the model group, all indicators above were reduced in all groups pre-treated by puerarin. Puerarin restrains the ceramide accumulation to block downstream p38 MAPK pathway and calcium ion rising, therefore reduces DNA damage in HaCaT cells induced by UVB.
