Abnormal expression of secreted protein acidic and rich in cysteine like 1 (SPARCL1 )gene is closely related to the development,metastasis and prognosis of a variety of tumors.Recent studies show that SPARCL1 gene is high expressed in glioma.The protein product of SPARCL1 gene encoded can interact with collagen,thus affecting the metastasis ability of tumor,which is positively correlated with tumor malignant de-gree.SPARCL1 gene is low expressed in gastric cancer,colorectal cancer,prostate cancer and breast cancer, which is negatively correlated with the invasion and metastasis abilities of tumors.At present,the role of speci-fic molecular mechanisms of SPARCL1 gene remains controversial. The expressions and functions of SPARCL1 gene in tumor tissues seem to depend on the tumor microenvironment.

Objectives To investigate the incidence of the heparin-induced thrombocytopenia (HIT) and positivity of anti-heparin/platelet factor 4 complex antibody (HIT-antibody) in inpatients treated with heparin preparations.Methods A total of 197 consecutive patients,including 120 men and 77 women,who were treated with unfractioned heparin (UFH) or low molecular weight heparin (LMWH),were enrolled in this study.HIT-antibody was detected by enzyme-linked immunosorbent assay (ELISA).All patients were classified into subgroups based on 4Ts (Pretest Clinical Scoring System) and types of underlying disorders.The incidence of HIT and positivity of HIT-antibody among different groups were analyzed.Results The overall incidence of HIT was 3.0％ (6/197),and the positivity of HIT antibody was 12.2％ (24/197).The positivity of HIT-antibody was 10.1％ (18/178),7.7％ (1/13) and 83.3％(5/6) in low,moderate and high HIT probability group respectively.There were significant differences of HIT positivity and mean level of HIT-antibody between the high HIT probability group and the low or moderate HIT probability group (P =0.000).Both the incidence of HIT and positivity of HIT-antibody were higher in surgical patients than in medical patients (5.8％ vs 0.9％,P =0.047 and 19.8％ vs 6.3％,P =0.004).Conclusions The incidence of HIT and positivity of HIT-antibody were 3.0％ and 12.2％ respectively,both of which were related with the types of disorders.Detection of HIT-antibody has a better applicable value in patients with high HIT probability.

Objective To investigate the status of self-management behaviors and sense of coherence (SOC) in patients with type 2 diabetes as well as their correlation. Method A total of 348 patients with type 2 diabetes participated in the survey by way of the general demographic data form, diabetes self-care scale (2-DSCS) and sense of coherence scale (SOC-13). Results The total score on 2-DSCS was (65.61 ± 14.55), and 17.24%of them were scored fairly well. The total score on SOC-13 was (63.25 ± 11.46), with an average score of (4.87 ± 0.88) on every dimension of it. The total score on 2-DSCS together with its dimensions was positively correlated with the total score on SOC-13(P<0.05, P<0.01). Conclusions The SOC and self-management in patients with type 2 diabetes should be enhanced. In order to improve the level of self-management, nurses should take some individualized interventional measures based on the level of SOC in patients.

High-speed counter-current chromatographic ( HSCCC ) method was successfully used to separate and purify prim-O-glucosylcimifugin and 5-0-methylvisammioside from Saposhnikovia divaricata(Thicz. ) Schis-chk. ,a traditional Chinese herb,with a solvent system composed of ethyl acetate-n-butanol-water(2:7:9,V/V). The lower phase of the system was used as the mobile phase at the flow rate of 2.0 mL/min,and the upper phase was used as the stationary phase. The separation produced a total 13.9 mg prim-O-glucosylcimifugin and 25.0 mg 5-0-methylvisammioside with the purity of 98. 1% and 99.2% determined by high performance liquid chromatography (HPLC) from 316 mg of crude sample from S. divaricata. The structures of isolated compounds were identified by ESI-MS,~1H NMR and ~(13)C NMR.

BACKGROUND:The etiological factor for rheumatoid arthritis remains unclear, but the effects of nuclear factor-κB on the onset of rheumatoid arthritis have been gradual y paid great attention by rheumatologists.
OBJECTIVE:By using the RNA interference (RNAi) technique to block the signal pathway of nuclear factor-κB
mRNA of human rheumatoid arthritis synovial cells, this study explored its application prospect in the treatment of rheumatoid arthritis.
METHODS:The synovial cells were isolated, digested, and cultured for further use. In accordance with the
design principle of smal interfering RNA (siRNA), target sequences of siRNA of nuclear factor-κB were identified, and siRNA expression vector of nuclear factor-κB was synthesized and constructed. The four pGenesil-1/nuclear factor-κB siRNA expression vectors were transfected into the first passage of synovial cells that wel grew. Blank and negative control groups were set. cells at 12, 24, 48, 72 hours, 5 and 7 days after transfection were col ected, and RNA was extracted. Intracellular nuclear factor-κB mRNA expression levels were measured, and siRNA plasmid vector that could effectively inhibit nuclear factor-κB mRNA expression was screened out.
RESULTS AND CONCLUSION:Nuclear factor-κB highly expressed in synovial cells after human rheumatoid arthritis. 3#pGenesil-1/nuclear factor-κB apparently suppressed nuclear factor-κB mRNA expression in synovial cells with human rheumatoid arthritis. RNAi technique blocked nuclear factor-κB mRNA expression. Therefore, the block of nuclear factor-κB signal pathway might be a good target for rheumatoid arthritis gene therapy.

Objective To explore the efficacy of tepronone and folic acid in the treatment of chronic atrophic gastritis (CAG) evaluated by the marking targeting biopsy (MTB).Methods A total of 224 H.pylori negative CAG patients were selected and divided into group A (n 96,tepronone 50 mg/time,folic acid 10 mg/time,three times/day),group B (n=23,tepronone 50 mg/time,three times/day),group C (n=74,unspecific treatment) and group D (n=31,no treatment).The treatment course lasted for one year.The clinical symptoms improvement of each group was observed before and after treatment.The pathological improvement of gastric mucosa by MTB was inspected before and after treatment.The chi square test was performed for the comparison between groups.Results The total efficacy rates of group A,B,C and D were 43.8％ (42/96),39.1％ (9/23),33.8％(25/74) and 32.3％ (10/31) respectively,there was no significant difference between groups (x2 =2.328,P =0.507).For the significant efficacy rate of gastric mucosa pathological improvement,group A was compared with group D,group A was compared with group C and group B was comparedwith group D,the differences were significant (x2 =14.520,14.628 and 8.995,all P＜0.01).In the total efficacy rate of gastric mucosa pathological improvement,group A (49.8％,131/263) was compared with group D (24.2％,16/66),group A was compared with group C (35.9％,66/184)and group B (44.7％,21/47) was compared with group D,the differences were significant (x2 =13.953,8.535 and 5.207,all P＜0.05).Conclusion Teprenone alone or teprenone and folic acid combination can obviously improve pathological changes of CAG patients.

Objective To explore the effect of decoction of four-drug juice plus glutamine on nutritional support in the elderly critically ill patients. Methods One hundred and twenty-four elderly critical ill patients in The First Hospital of Jilin University from May 2010 to May 2012 were randomly divided into treatment group(n = 62)and control group(n = 62). Patients in both two groups were given enteral nutrition(EN)plus parenteral nutrition(PN)after the hemodynamics became stable. In addition,patients in control group were given routine EN + PN,while in treatment group was given decoction o four-drug juice + EN plus glutamine + PN. Prealbumin (PA),serum total protein( TP),transferrin( TF)and serum albumin( ALB)were detected before and after treatment of nutritional support. The informations including recovery of bowel sounds,the occurrence of complications,antibiotic use time and the duration of ICU stay were recorded. Results There were no significant differences between two groups in terms of nutrition indices before treatment(P > 0. 05). After treatment,the contents of pre albumin,transferrin,total serum protein,serum albumin in treatment group were( 145. 24 ± 6. 72)g/ L,(1. 93 ± 0. 98)g/ L,(79. 86 ± 10. 38)g/ L,(54. 91 ± 2. 91)g/ L respectively,better than those in control groups((139. 24 ± 38. 76),(1. 68 ± 0. 33),(74. 73 ± 7. 31),(49. 87 ± 2. 61)g/ L),and the differences were statistically significant( t = 3. 610,2. 929,4. 360,6. 767;P < 0. 05). The incidence of stress ulcer and double infection in treatment group were 42%(26 / 62),37%(23 / 62),significantly lower than the control group(59%(37 / 62),53%(33 / 62)),and the differences were statistically significant( χ2 = 5. 186, 5. 271,P < 0. 05). Antibiotic use time and the duration of ICU stay in treatment group were(8. 82 ± 0. 71)d and(16. 14 ± 3. 01)d,and reaching full eternal nutrition time was(6. 90 ± 1. 01)d,decreased less than that in control group((10. 21 ± 1. 30),(20. 67 ± 2. 29),(13. 91 ± 1. 51)d)and the differences were statistically significant(t = 8. 892,7. 786,3. 609,P < 0. 05). The average recovery time of bowel sounds and first anal exhaust time average in treatment group were(26. 8 ± 3. 6)h,(25. 4 ± 3. 2)h,lower than that in control group ((38. 4 ± 4. 8)h,(37. 6 ± 4. 9)h)and the differences were statistically significant( t = 3. 551,2. 516,P< 0. 05). Conclusion The application of decoction of four-drug juice plus glutamine on nutritional support of the elderly critically ill patients can reduce complications,shorten the duration of ICU,recover the intestinal function as soon as possible. Meanwhile,patients can transit to full eternal nutrition as soon as possible,then the cost of therapy is reduced and rehabilitation is quickly.
