Chinese Journal of Immunology 1985;0(05):-
11 patients with chronic hepatitisB virus(HBV)infection were studiedby enumeration of T cell subsetsin peripheral blood withStaphylococco-SRBC DoubleRosette Forming Technique.It was found that T_3~+ cell subsetwas higher and T_4/T_8 ratio was sig-nificantly lower in patients withchronic HBV infection than in con-rol and higher numbers of doublelabeled cells (expressing both T_4 andT_8 antigens) were also found in pa-tients with chronic HBV infection.

0.05. Fixed effect model analysis showed that the summary RR was 1.43 (95%CI, 1.36 to 1.90), indicating a higher risk of future coronary heart disease in individuals with periodontal disease compared with those without. Conclusion This result suggests that periodontal disease is significantly related with coronary heart disease, they may be a risk indicator for each other. However, we should strengthen the prevention and cure of PD and control the probability of CHD.

Smooth muscle cell (SMC) proliferation, platelet free calcium level and aggregation of experimental atherosclerotic rabbits were investigated in this study. Aortic SMC ofhyperlipidemic rabbits in vitro showed higher growth activity than did normal rabbit SMC. And also hyperlipidemic serum stimulated SMC to proliferate at a significantly greater rate than control serum. Moreover, the level of platelet free calcium and the platelet aggregation was also higher in hyperlipidemic rabbits, indicating that activitated platelets possibly release more PDGF to act as a stimulator to SMC proliferation and calcium is an important factor to activate platelets. Furthermore, SMC from 8501-treated rabbits appeared lower proliferative rate than thecells from hyperlipidemic rabbits. And serum from those rabbits inhibited SMC proliferation compared with hyperlipidemic serum, the inhibitory effect was even stronger than that of normal serum. It may be relevant to the favorable effects of 8501 to TXA2/PGI2 balance.

Objective To reveal the expression and potential mechanisms of TGF?_1 and CTGF mRNA in liver of rats with nonalcoholic fatty hepatic fibrosis induced by highly fat-enriched diet.Methods The model group(10 rats) was fed with highly fat-enriched diet while the normal control group(10 rats) was raised by standard animal feeds for 24 weeks.Hepatic histopathological changes were evaluated,and RT-PCR method was used to assay TGF?_1 and CTGF mRNA expression levels in the liver.Results The analysis indicated that liver inflammation and fibrosis were apparently present in model rats.RT-PCR analysis revealed that the expression of TGF?_1 and CTGF in hepatic tissue were inreased in the model group as compared with the normal control group.Conclusions The rats model for hepatic fibrosis can be established by feeding with highly fat-enriched diet for 24 weeks.The expression of TGF?_1 and CTGF were enhanced in hepatic liver tissue of fatty hepatic fibrosis rats,and these changes might stimulate the fatty fibrosis.

Objective To investigate the changes of TNF-?,IL-2 and IL-1? level in serum of patients with viral myocarditis and its clinical meaning.Methods The level of serum TNF-?,IL-2 and IL-1? in 45 cases of viral myocarditis was detected by ELISA,and the data were compared with control group.Results Serum TNF-?,IL-2 and IL-1? levels in viral myocarditis patients were significantly higher than control group and related to severity of the disease.Conclusion It suggests that immune dysfunction exists in patients with viral myocarditis.Higher level of TNF-?,IL-2 and IL-1? may be associated with development of the viral myocarditis,and it can be a new indicator for viral myocarditis.

Objective To observe the relationship between C-reactive protein (CRP) and the stability of coronary artery lesions and major adverse cardiac events.Methods By using coronary arteriography,coronary heart disease was diagnosed in 30 stable angina patients and 45 unstable ones.serum CRP and troponin T (cTnT) levels were measured on 0hs,6hs,24hs,48hs and 7days after hospital admission.The patients were divided into two groups according to the absence or presence of major adverse cardiac events.Results There was no relationship between CRP level and the severity of coronary artery lesions,whereas the CRP level of unstable angina(3.9?0.4 mg/L)was much higher than that of stable angina(2.2?0.3 mg/L),P

Objective To explore the clinical value of the ten-point scale in the early diagnosis of fat embolism syndrome.Methods The data of 129 patients with fat embolism syndrome diagnosed by Gurd criteria admitted from January 1993 to February 2012 were analyzed retrospectively.At the same time,another 97 patients with single or multiple long bone fracture and/or pelvic fracture without fat embolism admitted from July 2005 to February 2012 were enrolled as control group.Patients were excluded if they had any of the following diseases:simple brain trauma,thoracic injury,spine fracture,hemorrhagic shock and the complications of cardiopulmonary cerebral resuscitation (CPCR).The patients of two groups were comparable in respect of clinical setting.The clinical data were analyzed and scored by the ten-point scale.The x2 test were applied to statistical works.Results Among all the clinical characteristics,the incidence of increased D-dimer was the highest (74.1%) in early fat embolism syndrome,followed by the progressive decrease in hemoglobin (63.6%) and hypoxemia (57.4%),and the occurrence of dyspnea was the lowest (17.8%).The percentage of total scores over ten points in patients with fat embolism syndrome group was higher than that in those without fat embolism syndrome (x2 =202.6,P < 0.01).The sensitivity of tenpoint scale was 96.12% and the specificity was 99.8%.Conclusions Ten-point scale could be used to make early diagnosis of fat embolism syndrome,thereby reducing the occurrence of misdiagnosis and misseddiagnosis.

Objective:To elucidate action mechanism of δ-tocotrienol in inducing apoptosis of human hepatoma HepG2 cells. Methods:Cell proliferation and viability were assessed by MTT assay; cell cycle distribution, apoptotic rate and mitochondrial membrane potential were measured by using high content screening system; the expression of apoptosis-related protein such as caspase-3, caspase-8, caspase-9, Bcl-2, Bax, tBid and cytochrome C in the HepG2 cells were evaluated by Western blotting. Results:δ-Toco-trienol inhibited HepG2 cell proliferation and induced apoptosis in a dose-dependent manner. This growth-inhibiting effect of δ-toco-trienol correlated with loss of mitochondrial membrane potential and release of cytochrome C from mitochondria to cytoplasm, and regulation of the protein expression of Bcl-2 family members, such as up-regulation of Bax and tBid and down-regulation of Bcl-2. Subsequently tocotrienol induced the activation of caspase-3, caspase-8, and caspase-9 which finally induced apoptosis of hepatoma HepG2 cells. Conclusion:δ-Tocotrienol induced apoptosis of human hepatoma HepG2 cells via mitochondrial pathway and membrane death receptor pathway.

Treatment with the combination of Chinese herbs and cytotoxic chemotherapies showed a higher survival rate in clinical trials. In this report, the results demonstrated that the tanshinone II A, a key component of Salvia miltiorrhiza bunge, when it is combined with the cytotoxic drug cisplatin showed synergistic antitumor effects on human prostate cancer PC3 cells and LNCaP cells in vitro. Antiproliferative effects were detected with MTT assay. Cell cycle distribution and apoptosis were detected by flow cytometer. Protein expression was detected by Western blotting. The intracellular concentration of cisplatin was detected by high performance liquid chromatography. The results demonstrated that tanshinone II A significantly enhanced the antiproliferative effects of cisplatin on human prostate cancer PC3 cells and LNCaP cells with the increase of the intracellular concentration of cisplatin. These effects were correlated with cell cycle arrested at S phase and cell apoptosis. The apoptosis might be achieved through death receptor pathway and mitochondrial pathway. Furthermore, the Bcl-2 family members were also involved in this apoptotic process. Collectively, these results indicated that the combination of tanshinone II A and cisplatin had a better treatment effect in vitro not only on androgen-dependent LNCaP cells but also on androgen-independent PC3 cells.
