OBJECTIVETo observe the intervention of Dachengqi Granule (DG) on the apoptosis of small intestine smooth muscle cells (SMCs) in rats with multiple organ dysfunction syndrome (MODS) and its mechanisms.

METHODSHealthy 100 adult Wistar rats were randomly divided into the control group (n =20), the MODS model group (n =40), and the DG group (n =40).E. coli suspension was peritoneally injected to rats in the model group and the DG group to establish bacterial peritonitis induced MODS model. DG at 1 mL/100 g was administered by gastrogavage to rats of the DG group, twice daily for 3 successive days. Twenty-four hours after modeling, the proximal segment of intestine was taken and stained by using terminal-deoxynucleotidyl transferase mediated nick end labeling (TUNEL) and immunohistochemistry. Changes of apoptosis quantity of SMCs and the expression of Bcl-2 associated X protein (Bax), B cell lymphoma/leukemia-2 (Bcl-2) and cytochrome c protein (Cyt c) in mitochondrial apoptotic signaling pathway were observed.

RESULTSCompared with the control group, the apoptosis quantity of SMCs and the expression of Bax and Cyt c protein significantly increased, and the expression of Bcl-2 protein significantly decreased in the MODS model group (P <0.01). Compared with the MODS model group, the apoptosis quantity of SMCs and the expression of Bax and Cyt c proteins significantly decreased, and the expression of Bcl-2 protein significantly increased in the DG group (allP <0.01).

CONCLUSIONDG could inhibit apoptosis of SMCs through suppressing activation of mitochondrial apoptotic signaling pathway in intestinal SMCs, thus promoting the recovery of the gastrointestinal motility function in rats with MODS.

Panax japonicas C.A. Meyd are mostly produced in southwestern China. It is widely used by Tujia and Miao nationality. It has the actions of reinforcing deficiency and being strong, reducing swelling and paln, dissolving stasis and stopping bleeding. Total saponins ofPanax japonicas (TSPJ) are principal active component ofPanax japonicas C.A. Meyd. The researchers found that it had remarkable therapeutic effects on the diseases, especially rheumatism and cardio-cerebrovascular in recent years. This article is to summarize the pharmacological actions of TSPJ and to provide the references for future studies.

Objective The application value of CTA for BA in interventional theray of lung cancer.Methods 15 patients with lung cancers including central type(13 cases)and peripheral type(2 cases) proven by pathology were analyzed prospectively.They were all examined with contrast enhanced.MDCT and the data were sent to the workstation and reconstructed with thin section multi-planar reformation(MPR),maximum intensity projection(MIP)and volume rendering(VR).Results All cases of central type lung cancer were supplied by the bronchial artery including two by the bronchial artery and intercostal artery,clearly demonstrated on the scans with the origin,branches and routes.One case of peripheral lung cancer was supplied by the bronchial artery and the other could not find the definite supplying artery.Conclusions CTA of BA for lung cancer can provide the accurate localization and other reference data for interventional therapy.

OBJECTIVE: Comparative analysis of the clinical curative effect of manipulative reduction and TRV- CRP treatment of BPPV, comfort degree during reset and quality of life improvement. METHOD: One hundred and thirty-two patients with BPPV were randomly divided into two groups ,one group underwent the traditional manip- ulative reduction, the other group with TRV-CRP. DRI and VAS was evaluated in the pre and after treatment and evaluation of the efficacy was conducted. The results of two groups were compared. RESULT: The effective rate of manipulative reduction after a week treatment was 89. 23% and TRV-CRP.was 98. 51%, which was higher in TRV-CRP group than that of the manipulation reduction group(P<0. 05). The comfort degree of the manipulation reduction group was 4. 54±2. 48,higher than the TRV-CRP group which was 5. 48±1. 44 (P<0. 05). The score of DHI showed no significant difference before treatment between manipulation reduction group and TRV-CRP group(P>0. 05), the score of the two groups were decreased after a week of reduction, but the improvement of TRV-CRP group was higher than that of manipulation reduction group(P<0. 05). CONCLUSION The success rate of TRV-CRP was higher than that of manipulative reduction,but manipulative reduction comfort degree was higher than TRV-CRP, the two methods can both improve the quality of life of patients with BPPV. TRV-CRP has many advantages over manipulative reduction, but manipulative reduction is simple with low cost, and the effect is still a great advantage. In clinical work, we should reasonable combine the two methods,so as to improve the cure rate of RPPV.

OBJECTIVETo investigate the species of Ligularia distributed in the northwestern China and their medicinal uses in the local area.

METHODField investigation, specimen collection, taxonomic study and datum check were adopted.

RESULTThere are 29 species and 1 varieties of Ligularia distributed in the northwestern China, and 18 species of them had been used as folk medicines with the function of resolving phlegm, relieving cough, clearing heat and toxins.

CONCLUSIONThe northwestern China is abundant in medicinal resource of Ligularia.

OBJECTIVE To investigate the distribution of bacteria in general ICU then discuss the susceptible factors and the treatment.METHODS A retrospective analysis of clinical information was performed on 123 patients diagnosed infection who stayed in ICU from May 2002 to May 2004.RESULTS Most of bacteria resulted in infection of general ICU were Gram-negative(62.88%) and then Gram-positive(19.65%). Fungal infection accounted for 17.47%.Pseudomonas aeruginosa occupied the highest percentage among Gram-negative bacteria.Most of Gram-positive bacteria were Staphylococcus aureus and all of them were MRS.The infection site in ICU focused on lower respiratory tract(89.09%).The second was urinary tract(11.79%).CONCLUSIONS Most of the bacteria causing infection in general ICU locate in respiratory tract.They are mainly Gram-negative.All of the Gram-positive bacteria are MRS.The risk factors of hospital-acquired infection are related with patient′s age,underlying disease,intensive care time,ventilation time and invasive operation.

Objective To study the effect of two-step pretargeting radioimmunotherapy of CD45 McAb and 188Re-Avidin on lymphoma Raji cell line.Methods The CD45 McAb and Avidin were directly labeled with 188Re,and the labeling efficiency and radiochemical purity were measured by the paper chromatography.The specific binding test and competition binding test between 188 Re-CD45 McAb and Raji cells in vitro were also performed.CCK-8 assay was used to determine the inhibition effect on Raji cell proliferation in the pretargeted group,188Re-CD45 McAb,188Re-Avidin and 188ReO4 groups,then the cell survival and proliferation inhibition rate were calculated.Results The specific cell binding rate of 188Re-CD45 McAb with Raji cells was (70.92 ± 1.91) ％,in the competition group,the binging rate of 188Re-CD45 McAb with Raji cells was only (7.96 ± 0.87)％.The Raji cells proliferation was inhibited in all groups with 188Re radiolabel,and the inhibition rate was positively correlated with the radioactivity dose (r=0.907-0.992,P ＜0.05).However,at the same dose,the inhibition effect in the group of two-step pretargeting at each time point were all stronger than those of 188Re-CD45 McAb,188Re-Avidin and 188 ReO4-alone (t =124.76-607.98,P ＜ 0.05).But there was no significantly statistical difference in the inhibitory effect between the groups of 188Re-Avidin and 188ReO4-(P ＞ 0.05).Conclusions It is confirmed that 188Re-CD45 McAb could be specifically bound to Raji cells,and the two-step pretargeting of CD45 McAb and 188Re-Avidin has obvious inhibitory effect on the Raji cell proliferation.
