Objective To explore the changes and role of levels of serum IL-18 and IL-13 in children with Guillain-Barr? syndrome(GBS).Methods The levels of serum IL-13 and IL-18 were determined by enzyme-linked immunoabsordent assay(ELISA)in 42 children with GBS(GBS group)in stages of acute and recovery,and compared with the normal control(NC)group.Results The serum levels of IL-18 and IL-13 in GBS group at acute stage[(44.87?7.53)pg/ml,(37.46?6.94)pg/ml] were significantly higher than those at recovery stage[(38.25?5.86)pg/ml,(32.14?6.89)pg/ml] and NC group[(32.35?4.93)pg/ml,(24.76?5.59)pg/ml](all P

It had been proved by many evidences that several heat shock proteins (HSPs) expression is up-regulated in tissue-derived primary lung cancer, and HSPs may play important roles in development, in resistant to drugs and in prognosis of lung cancer. However, there have not still systemic research on which HSPs,especially HSP70 can be or not thought as a new biological target in the therapy to lung cancer. In order to address the expression and roles of heat shock protein 70 (HSP70) in lung adenocarcinoma, immunoblotting was performed to detect the expression of HSP70 in tissue specimens from lung adenocarcinoma which were diagnosed unambiguously by branch fibromicroscopy and were excised. It showed that in the normal lung tissues, the expression of HSP70 was less then that in cancer tissues. After down-regulation of HSP70 protein by HSP70 anti-sense oligonucleotides in A549 cell line, MTT assay showed that the proliferation of A549 cells was inhibited remarkably after the treatment with HSP70 antisense oligonucleotides and Act D. There had significant differential in HSP70 antisense treatment group followed by Act D treatment and Act D treatment group. Results of Hoechst33258 staining revealed that HSP70 antisense oligonucleotides could promote Act D-mediated apoptosis in A549 cells with a higher percentage of apoptotic cells (26.91?3.73)% than that of Act D-treated group (16.83?3.41)% (P

Objective To observe effects of four extracts (water, n-butanol, acetoacetate and petro-leum benzine extracts) from Hippocampus japonicus on kidney-yang deficiency mice induced by extradiol, and reveal the modern scientific connotation about sweet-flavor, warm-nature, meridian tropism in liver and kidney. Methods Kidney-yang deficiency mice was induced by intraperitoneal injection of estradiol benzoate. Effects of four extracts from H. japonicus were observed by measuring physical signs, rectal temperature, grip strength, swimming time, autonomic mobility, creatinine (Cr) and urea (UR) level in serum, haematological indexes, testis index and seminal vesicle index. Results All the four extracts from H. japonicus could markedly improve physical signs and increase seminal vesicle index, RBC, Hb and PLT in blood, and decrease UR level in serum of kidney-yang deficiency mice, water extract and petoleum benzine extract could increase rectal temperature, grip strength, swimming time, autonomic mobility, testis index, WBC, lymphocyte (LY), monocyte (MO), and neutrophilic granulocyte (NE), n-butanol extract could increase autonomic mobility and NE, acetoacetate extract could enhance grip strength and prolong swimming time. Conclusion All above effects of extracts from H. japonicus could be as the basic of improving kidney-yang deficiency, could be an important part of the modern scientific connotation about sweet-flavor, warm-nature, meridian tropism in liver and kidney. Effects of water extract and petroleum ether extract were closer and stronger, which offer enlightenment for searching the common effective substance groups of H. japoniacs.

OBJECTIVETo study the effect and its mechanism of antihypertensive of drug combination of Jimaitong tablt and nifedipine on spontaneously hypertensive rats.

METHODThe spontaneously hypertensive rats (SHR) were treated by intragastric administration (ig) with Jimaitong (450 mg x kg(-1)), Jimaitong (300 mg x kg(-1)) combined with the nifedipine (0.5 mg x kg(-1)), nifedipine (5 mg x kg(-1)) for 8 weeks. Blood pressure and heart rate was measured. The level of oxidation indicators, lipid indicators, as well as hormones related to blood pressure was detected.

RESULTSCompared with that in the control group, systolic blood pressure, diastolic blood pressure, mean arterial pressure of SHR decreased significantly in all the three administration groups (P < 0.01). Heart rates of nifedipine group was faster than other groups (P < 0.05). In combination group, contents of URE, MDA, ET and Ang II were decreased significantly (P < 0.05, P < 0.05, P < 0.05, P < 0.01), the contents of NO and CAMP, SOD and NOS were significantly enhanced (P < 0.05).

CONCLUSIONCombination use of Jimaitong and nifedipine has synergistic effects on anti-hypertension in spontaneously hypertensive rats. It indicates the potential applications of combination of traditional Chinese medicine and western medicine for the hypertension treatment.

OBJECTIVETo observe the effects of three traditional Chinese medicine (TCM) such as Amomi Fructus Rotundus, Perillae Folium and Angelicae Dahuricae Radix on lung-yang deficiency rats induced by compound factors.

METHODLung-yang deficiency rats were established with three-factor combination, such as smoking (exogenous evil effect on lung), swimming in common and ice water (cold body and exhaustoin) and drinking ice water (inhale cold). Meanwhile, rats were given water extracts of the three TCM by intragastric administration for 24 days everyday. Indexes such as general behavior, weight, rectal temperature, back temperature and grip strength were observed. Blood was collected to determine NO, IgG in blood serum. Lung and heart were dissected to measure organs index.

RESULTThe water extracts of Amomi Fructrs Rotundus, Perillae Folium and Angelicae Dahuricae Radix could markedly heighten weight, back temperature, grip strength, content of IgG in blood serum, reduce content of NO in blood serum, lung index and heart index. The water extracts of Amomi Fructrs Rotundus and Perillae Folium could heighten rectal temperature.

CONCLUSIONAmomi Fructrs Rotundus, Perillae Folium and Angelicae Dahuricae Radix were TCM with pungent-flavor, warm-nature and meridian tropism in lung, which could improve the symptoms of physique emaciation, aversion to cold of the back, weary and acratia and so on. It provides an important reference for the regularity of the properties theories about pungent-flavor, warm-nature and meridian tropism in lung.
