Objective To study the induction of IL-6 on expression and activity of tissue factor (TF)in peripheral blood monocytes(PBMCs).Methods rhIL-6 100 ng/L and rhIL-6 100 ng/L+ rhIL-6 MoAb 10?g/L were used respectively to stimulate the PBMCs for 24 h,PBMCs without any stimulation as control group,to study the changes of antigen content,mRNA expression and the ac- tivity of the TF.Results The antigen content,mRNA expression and activity of TF were increased significantly in 100 ng/L rhIL-6 group as compared with rhIL-6 100 ng/L+rhIL-6 MoAb 10?g/L and control groups(P＜0.01).Conclusions rhIL-6 can induce the increase of antigen expression,activity and mRNA expression in PBMCs,and these effects can be suppressed successfully by rhIL-6 MoAb. This study demonstrated that there was potential relations between cytokines and thrombogenesis, which may play an important role the pathogenesis of chronic rejection.

OBJECTIVE To study the risk factors and clinical characteristics of nosocomial infection in senile patients with acute myelogenous leukemia who received chemotherapy.METHODS Ninety-one cases of senile patients with acute myelogenous leukemia received 304 times of chemotherapy with etiological examination,to analyze the relationship between nosocomial infection and absolute neutrophil count in peripheral blood,the cellularity of the marrow and chronic systemic disorder.RESULTS All indicators of senile patients with acute myelogenous leukemia were higher than those of younger patients(P0.05).CONCLUSIONS Age,different stage of chemotherapy,the neutrocytopenia level and prolongation,and hypocellularity of bone marrow are related to the nosocomial infection in senile patients with acute myelogenous leukemia,and the chronic systemic disorder is not a risk factor.

Objective To explore the effect of?-3 fish oil fat emulsion on the release of pro-inflam- matory cytokines in patients with systemic inflammatory response syndrome(SIRS).Methods Forty patients with SIRS in the intensive care unit(ICU)from June 2006 to June 2007 were randomly divided into routine total parenteral nutrition(TPN)group(group A,20 cases)and?-3 fish oil fat emulsion+TPN treatment group(group B,20 cases).All the patients received treatment of parenteral nutrition with equal nitrogen content and calories.The caloric value given was 83.68 kJ?kg~(-1)?d~(-1),with 0.2 g?kg~(-1)?d~(-1)of nitrogen. Group A patients received routine TPN,and group B patients received TPN with?-3 fish oil fat emulsion 1-2 ml?kg~(-1)?d~(-1),and both regimes lasted for 7 days.The levels of serum tumor necrosis factor-?(TNF-?),interleukin-1(IL-1)and IL-6 were checked before the treatment,and on the 1st,3rd and 7th day after the beginning of the treatment.The duration in ICU,the incidence of multiple organ dysfunction syndrome(MODS)and the mortality rates in 28 days of the two groups were also assessed.Results Compared with the routine treatment group,the levels of serum TNF-?,IL-1,and IL-6 in the?-3 fish oil fat emulsion+TPN treatment group were lower markedly(P0.05).Conclusion The emulsion of?-3 fish oil fat seems to have a protective effect on patients with SIRS through decreasing the levels of serum TNF-?,IL-1 and IL-6,thus reducing the incidence of MODS,shortening the ICU stay, and increasing the survival rate of serious patients.

OBJECTIVETo investigate the effect of bone resorption by odontogenic cysts and ameloblastomas in vitro.

METHODSFragments of odontogenic cysts (14 odontogenic keratocysts, 6 inflamed odontogenic keratocysts, 5 dentigerous cysts) and ameloblastomas (n = 7) were incubated in vitro for 24 h. The supernatant was then removed into the culture system of SD rat calvaria. After incubation (48 h), the calcium contents of the media were measured by atom spectrophotometer. The supernatant of odontogenic cysts and ameloblastomas was measured for the bone resorption related factors such as IL-6, TNF-alpha, PGE(2), bone Gla-containing protein (BGP) and calcitonin (CT) by a radioimmunoassay system.

RESULTSThe calcium released in the calvaria culture media by all the odontogenic lesions was significantly higher than that in the blank controls (P < 0.01). The inflamed odontogenic keratocyst group had a significantly higher calcium concentration than odontogenic keratocyst and ameloblastoma groups (P < 0.05). In addition, the concentration of IL-6, TNF-alpha, PGE(2) and CT in the culture media of all odontogenic lesions were significantly higher than that of the blank controls (P < 0.05). IL-6 concentration in the inflamed and non-inflamed odontogenic keratocyst groups were significantly higher than that of ameloblastoma group (P < 0.05). CT concentration in the inflamed odontogenic keratocyst was significantly higher than those of odontogenic keratocyst and dentigerous cyst groups (P < 0.05). Correlation and regression analysis showed that IL-6 was significantly correlated with the calcium content (P < 0.01).

CONCLUSIONSThe odontogenic lesions could promote bone resorption in vitro and it is likely to be related to some of the cytokines secreted by the lesions.

OBJECTIVETo summarize and analyze the compatibility laws for acupoint selection of acupuncture in treating diabetic gastroparasis (DGP) in modern literatures of clinical researches.

METHODSRetrieved were literatures related to treating DGP by acupuncture or acupuncture combined other therapies from PubMed, CNKI, and WF from 1982 to 2014. Analyzed were frequency of acupoint use, meridians selected acupoints belonged to, regions selected, association laws of selected compatible acupoints.

RESULTSRetrieved were 35 with compatibility frequencies more than 15 listed as follows: compatibility frequency of Zusanli (ST36) and Zhongwan (CV12) was 33 (94.29%); compatibility frequency of Zusanli (ST36) and Neiguan (PC6) was 23 (65.71%), compatibility frequency of Zhongwan (CV12) and Neiguan (PC6) was 22 (62.86%), compatibility frequency of Zusanli (ST36), Zhongwan (CV12), and Neiguan (PC6) was 22 (62.86%); compatibility frequency of Zusanli (ST36) and Sanyinjiao (SP6) was 16 (45.71%); compatibility frequency of Zhongwan (CV12) and Sanyinjiao (SP6) was 16 (45.71%); compatibility frequency of Zusanli (ST36), Zhongwan (CV12), and Sanyinjiao (SP6) was 15 (42.86%). Meridians selected acupoints belonged to were sequenced as Foot Yangming Stomach channel, Ren channel, Foot Taiyang Bladder channel, and so on. Acupoints selected were mainly in lower limbs, chest and abdomen, waist and back. The compatibility of Zusanli (ST36) and Zhongwan (CV12) was the most often used with the highest frequency.

CONCLUSIONSThe compatibility laws for acupoint selection of acupuncture in treating DGP were mainly dominated as upper-lower selection, three regions selection, local selection, anterior-posterior selection. The compatibility laws for acupoint selection of acupuncture along meridians were mainly dominated as the convergence points and exterior-interior meridian points.

To investigate the effect of acid and alkali stress on ginsenoside content of Panax ginseng, adventitious roots culture in bioreactors were incubated for 30 d and pH value was adjusted. Ginsenoside content increased by reducing or raising the pH in culture medium, the muxium ginsenoside content was determined on the 5th days after acid treatment and on the 7th days after alkali treatment. The result of histochemical localization of ginsenoside revealed that the red color from light to dark were found in the adventitious root tissue, and ginsenoside mainly located in the pericycle cells where appeared the dark red color.
