Objective To explore a new method of parapancreatic abscess treatment and establish an idea of minimally invasive technologies for parapancreatic abscess to improve the recovery rate of acute pancreatitis. Methods The patients had experienced percutaneous puncture and placed drainage tube under the ultrasound guidance first, then the sinus tract was expanded gradually to 24F perimeter by Cook's fascia expender. Finally, the necrotic tissue and pyogenic membrane was removed and repeatedly washed under guidance of choledochoscopy. Results The recovery rate was 91.1 %(33/36). The complication incidence was 10.7% (hemorrage:2 cases, external intestinal fistula:3 cases, and fatal MOF: 1 case). Conclusions The viewpoint which parapancreatic abscess only can be cured by drainage operation can be changed by associating debridement by choledochoscope with percutaneous puncture drainage under the ultrasound guidance. It is a simple, safe and effective method. It can be used to reduce the patients' damage, complication and mortality and accomplish the idea of damage control by minimally invasive technologies.

Objective To study the expression of monocyte chemotactic factor -1(MCP-1) and fibronectin (FN ) in secondary acquired middle ear cholesteatoma epithelium ,and to investigate the ability of cholesteatoma of e-rosion .Methods MaxVisionTM immunohistochemical method was used to detect the expression of MCP -1 and FN in the secondary acquired middle ear cholesteatoma tissues from 30 patients ,in the retroauricular skin from 20 pa-tients and in the retroauricular skin from 16 normal subjects .Then we scanned it into a computer by an image scan-ner and quantified the gray value of them using commercial software .Results MCP-1 appeared to be localized in all epithelial layers of middle ear cholesteatoma ,particularly in the spinous layers .The positive expression rates of MCP-1 was 70% ,the gray value was 147 .2 ± 20 .1 ,which were siginificantly higher than those of in the retroau-ricular skin from patients(35% ,200 .8 ± 18 .4)and from normal subjects(37 .5% ,193 .3 ± 15 .5)(P<0 .05) .The ex-pression of FN in all epithelial layers of middle ear cholesteatoma were abundantly stained ,especially in the basal and spinous layers and the matrix of cholesteatoma .The positive expression rates of FN was 76 .7% ,the gray value was 147 .2 20 .1 ,which were siginificantly higher than those of in the retroauricular skin from patients (30% ,195 .0 ± 12 .9)and from normal subjects(31 .3% ,191 .6 ± 13 .5)(P<0 .05) .It showed statistically significant correlation between the expression of MCP -1 and FN and the erosion ability of middle ear cholesteatoma (rmcp-1 = -0 .682 , rfn = -0 .531 ,P<0 .01) .There was not linear correlation between the expression of MCP -1 and FN .Conclusion MCP-1 and FN are overexpressed in middle ear cholesteatoma .There was correlation between the expression of MCP-1 or FN and the erosion ability of middle ear cholesteatoma ,indicating that MCP -1 and FN may play an im-portant roles in invasive behavior of cholesteatoma .

0.05). At time points of end of cold preservation, 10, 30 and 60 min of reperfusion, the activity of p38MAPK in control group was significantly higher than that at the time points of before resection and 120 min of reperfusion (P0.05). The expressions of TNF-? mRNA and ICAM1 mRNA at the time points of before resection, end of cold preservation, and 10 and 30 min of reperfusion were significantly lower than those in 60 and 120 min of reperfusion in both two groups (P

Objective To expand the utilization of minimally invasive technologies for parapancreatic abscess,and summarize the application experience of choledochoscope for treatment of parapancreatic abscess.Methods The clinical data and treatment effectiveness of 36 patients with parapancreatic abscess from Dec.2000 to Dec.2008 were analyzed retrospectively.These patients had experienced percutaneous puncture and been placed drainage tube under the ultrasound guidance first,then expanded the sinus tract gradually,and performed debridement by choledochoscope.The flexibility of choledochoscope was used to remove the necrotic tissue and pyogenic membrane repeatedly by clamping,netting and vacuum aspiration in every domain.Results Thirty-six patients were performed percutaneous puncture and placed drainage tube,3 cases were given canalis singularis,7 cases were double tube,26 cases were over three tube.The debridement times were 3-14 by choledochoscope,average 5.6 times.There were 6 cases with improving systemic symptoms,blood routine and temperature recovering normal,and drink and food recovering,then discharged from hospital with tube after 1-2 times of debridement.Length of stay was 25-132 d,average 76 d.The curing rate was 91.7% (33/36).Two cases were turned into open surgery because of broad necrotic tissue range combined with many abdominal cavity abscess with good postoperative recovery and cured.One case was dead of severe multiple organ failure combination.There were 2 patients with hemorrhage,3 patients with external intestinal fistula.Conclusions The debridement of choledochoscope for parapancreatic abscess treatment is a simple,flexible and effective method.It changes the viewpoint that parapancreatic abscess can be cured only by operation drainage,decreases the patients’ trauma and accomplishes the idea of damage control by minimally invasive technologies.

This paper reported the suitable medium of L S-1 stain in detail,which could yield natural blue pigment.Single-factor exper imental design shows that the best carbon source was 2% glucose and nitrogen was 0 1% KNO 3.Orthogonal experimental design shows that the most suitable fermen tation medium was consisted of 4% glucose,0 1% KNO 3,0 075% salt and 10?g/m L FeSO 4.The best cultivation temperature was 30℃ and pH7 4.The dissolved oxyg en on the process of fermentation,as well as the variety of pH and the utilized condition of carbon and nitrogen were measured and analyzed.The separation of th is blue pigment by HPLC shows that this material contains actinorhordin and at l east other four ingredients.

OBJECTIVETo explore the effect of peimine on excision repair cross-complementation 1 (ERCC1) mRNA and lung resistant protein (LRP) expressions in A549/cisplatin (DDP) multidrug resistance (MDR) cell line.

METHODSLung cancer A549/DDP cells were cultured in vitro.Cells at logarithmic growth phase were divided into 4 groups, i.e., the blank control group, the DDP group, the ligustrazine group (DDP+ligustrazine), the peimine group (DDP + peimine). After 48-h drug action, ERCC1 mRNA expression was detected by RT-PCR and LRP expression detected by cell immunofluorescence.

RESULTSThere was no statistical difference in expression levels of ERCC1 mRNA and LRP between the DDP group and the blank control group (P > 0.05). Compared with the DDP group, expression levels of ERCC1 mRNA and LRP obviously decreased in the ligustrazine group and the peimine group (P < 0.05). They were obviously lower in the peimine group than in the ligustrazine group (P < 0.05).

CONCLUSIONSPeimine could reverse MDR of A549/DDP cell line. Its mechanism might be associated with down-regulating ERCC1 mRNA and LRP expression levels.

OBJECTIVETo discuss the drug intervention in diversity changes of TCRVbeta gene in AIDS patients with incomplete immune reconstitution.

METHODPBMCs were isolated from 37 cases of AIDS patients failure to immune reconstitution before and after treatment with Immune 2 and 15 cases of HIV negative healthy donors. The human gene TCRVbeta CDR3 diversity quantitative detection reagent box were used, and mapped the distribution of gene scanning and calculated different CDR3 fragme of each Vbeta family size.

RESULT(1) Gaussian distribution of TCRVbeta families in patients with incomplete immune reconstitution after one year of HAART, had been broken with the occurrence of the offset TCR lineage. After six months of treatment of traditional Chinese medicine combined HAART, the TCR lineage has been partially restored. (2) Evaluated by the D (distance) value calculated by a quantitative analysis software which the kit provides, there were no significant difference in D value change between the two groups, but with traditional Chinese medicine can reduce the data variability. (3) CD4+ T cell counts had a significant correlation (r = -0.772, P = 0.000) with TCRVbeta genetic diversity.

CONCLUSIONStudy of the mechanism showed oligoclonal of TCRVbeta family can get recovery in some degrees after treated by Immune 2 plus HAART, suggesting that the medicine may promote T-cell receptor gene rearrangement, helping immune cells to effectively identify the virus to reduce T-cell apoptosis.

The study was to research the clinical characteristics of Shenmai injection treating tumor based on hospital information system, including the characteristics of the age, the sex, the dosage, the course of the treatment and the combination drugs. The data of tumor patients injected with Shenmai injection was analyzed. The information was collected from the hospital information system (HIS) in twenty hospitals of grade III-A. The method of frequencies and association rules was used in this reaearch. The patients over 45 years old were up to 3 338, about 79.36% of the whole. The ratio of male and female was 1.73: 1. The hospitalization day between 15 and 28 was most. The complications of the hypertension and coronary heart disease happened most. The support was 5.939% and 5.099% respectively. Fifty-five patients had the traditional Chinese medicine (TCM) syndrome of Qi-Yin deficiency, about 14.78% of the whole. There were 8 491 patients treated with the single dose of 81 to 100 mL, about 48.70% of the whole. The main combination drugs were dexamethasone, tropisetron and maxolon. The confidence was 44.63%, 31.22% and 20.53% respectively. The information from HIS showed that tumor patients used Shenmai injection were most quinquagenarian with smooth condition. The dose of the Shenmai injection sometimes was higher than that of the drug use instructions in clinical. Shenmai injection was most often combined with glucocorticoid, antemetic and nutritional support medicine when treating tumor in clinical.
