Objective To investigate the role of ribosomal S6 kinase (RSK) in the pathogenesis of rat hepatic fibrosis. Methods Intra-abdominal injection of dimethylnitrosamine was carried out to (establish) the model of rat experimental hepatic fibrosis. Immunofluorescent double labeling laser scanning (confocal) microscope was performed to detect the location of RSK, ?-smooth muscle actin(?-SMA) and the collagen type Ⅰ. Immunohistochemistry was used to determine the correlation of the expression of RSK and collagen type Ⅰ, Ⅲ in the tissue of hepatic fibrosis. Results In the tissue of hepatic fibrosis, RSK was coexpressed with ?-SMA, and the collagen type Ⅰ located around RSK. The expression of RSK was also correlated with that of collagen type Ⅰ and Ⅲ( P

Objective To investigate the expressions of CXC chemokine 10(CXCL10) in chronic non-atrophy gastritis(CNAG) , precancerous lesions(PL)and gastric cancer(GC) ,primitively understanding of CXCL10 expression levels in three gastric types ,ex-ploring their clinical significances .Methods The expressions of CXCL10 in 20 cases of CNAG ,60 cases of PL ,60 cases of GC tis-sues were examined with immunohistochemistry method ,the expression level of CXCL10 was analyzed by computer-assisted image analysis system ,and then analyzed statistically .Results CXCL10 expression were positive in parts of CNAG ,PL and GC the posi-tive rates were 10 .00% ,26 .67% ,71 .67% respectively) .Expression levels of CXCL10 in the GC tissue specimens were significant-ly higher than in CNAG and PL(P<0 .01) .Expression levels of CXCL10 in the PL and CNAG tissue specimens have no significant difference(P>0 .05) .Expression levels of CXCL10 in CAG with IM ,CAG with Dys had no significant difference(P>0 .05) ,and in CAG with Severe Dys and Light-Moderate Dys had no significant difference(P>0 .05) .The expression levels of CXCL10 were rele-vant to the differentiation degree of GC (P>0 .05) .Conclusion The expression levels of CXCL10 were gradually rose from CNAG , PL to GC ,and had significant correlation with each other in CNAG ,PL and GC ,indicating that CXCL10 have a key role in the pro-duce and development of GC .

AIM: To observe the effect of intravenous methylprednisolone combined with peri - orbital injection of triamcinolone acetonide for diffuse - type orbital inflammatory pseudotumor.
METHODS: Diffuse - type orbital inflammatory pseudotumor in 15 cases ( 19 eyes ) were treated. Intravenous implosive methylprednisolone therapy (0. 5g/ d) was used in the first 3d, and 0. 5g once a week in the following 3wk, ended by 0. 25g once a week in the last 6wk, which meant the total dose was 4. 5g and the whole course lasted for 10wk. At the same time, peri - orbital injection of triamcinolone acetonide ( 40mg ) was performed once in every 3wk, totally 2-4 times.
RESULTS: Eight eyes from 7 cases were completely cured, 11 eyes from 8 cases were partly cured. No recurrence and severe complications were observed in the treatment duration.
CONCLUSION: Intravenous methylprednisolone combined with peri - orbital injection of triamcinolone acetonide is effective, safe and feasible in treatment of diffuse type orbital pseudotumor with less complications.

Objective To analyze the clinical features of fungal septicemia in premature infants in a hospital,and provide reference for clinical diagnosis and treatment.Methods Clinical data of 18 premature infants with fungal septicemia in a hospital between January 2011 and December 2013 were analyzed retrospectively.Results Gesta-tional ages of 18 premature infants were 27-36 weeks,birth weights were 1 050 g-3 100 g,8 of whom were very low birth weight infants(VLBWI);all premature infants were treated with broad-spectrum antimicrobial agents,and were given long-term parenteral nutrition before infection,10 with mechanical ventilation,2 with peripherally insert-ed central catheters(PICC).The main clinical manifestations were apnoea,twitch,feeding difficulty,and poor reac-tion;manifestations appeared 3 hours-52 days after birth.13(72.22%)premature infants had abnormal white blood cell count,12 (66.67%)had thrombocytopenia (< 100 × 109/L),18 (100.00%)had elevated C-reactive protein (CRP),the average CRP level was (41 .90 ±26.77)mg/L.The main pathogens were Candida spp .(n = 17, 94.44%),including Candida parapsilosis (n=7),Candida albicans (n =5 ),biovariety of Candida albicans (n =4),and Candida famata (n=1);premature infants were treated with fluconazol and amphotericin B,15 (83.33%) were cured,2 (11 .11 %)improved,and 1 (5.56%)died.Conclusion Fungal septicemia in premature infants are mainly caused by Candida,there is no specific clinical manifestations,clinical symptoms in premature infants with high risk factors should be closely observed,blood routine and CRP should be detected periodically,timely treat-ment with antifungal agents should be given,which are beneficial to achieve good therapeutic effect.

Objective To study the relationship between clinicopathological features and central lymph nodes metastasis in patients with papillary thyroid microcarcinoma(PTMC).Methods From Jan.2013 to Jun.2013,400 cases with PTMC in cN0 stage undergoing thyroidectomy and central neck dissection were collected.Results Univariate analysis showed that the rate of central lymph node metastasis in PTMC was 28.0％,nevertheless,the rate of central lymph node metastasis was 32.5％,42.6％,44.1％,33.3％,and 37.4％ respectively in patients aging below 45 years old,in male patients,in patients with extrathyroidal extension,in patients with tumor diameter larger than 5 mm and in patients with multifocality.Gender,age,extrathyroidal extension,tumor diameter,multifocality of patients had correlation with central lymph node metastasis.Multivariate binary logistic regression analysis revealed that the rate of lymph node metastasis significantly increased in cases of male,ageing below 45 years old,with extrathyroidal extension and multifocality(P ＜ 0.05).Conclusions The treatment for central lymph node metastasis of PTMC should be different considering elements including gender,age,multifocality of the tumor,and extrathyroidal extension.Prophylactic central lymphadenectomy should be performed when the primary lesion was resected.
