OBJECTIVETo observe interventional effects of anti-viral therapy and Compound Qin-gre Granule (CQG) on host cellular immune functions of acute virus infection patients.

METHODSThirty acute virus infection patients were recruited to detect peripheral lymphocyte subsets. They were randomly assigned to two groups, the Western medicine treatment group (treated with anti-virus Western medicine) and the integrative medicine treatment group (treated with anti-virus Western medicine plus CQG). T-cell subsets were re-examined 7 days later. Changes between before and after treatment were observed. Effect on host cellular immune functions and efficacy were compared between the Western medicine treatment and the integrative medicine treatment.

RESULTSCompared with the normal control group, the percentage of peripheral T cells increased, and the percentage of B/NK cells decreased in acute virus infection patients (P < 0.01). Meanwhile, in T cell subsets, the percentage of CD8+ T cells and CD8+ CD38+ T cells increased (P < 0.05, P < 0.01); and percentages of CD4+ T cells, CD4+ CD28 + T cells, and CD8+ CD28+ T cells decreased (P < 0.05, P < 0.01). After one-week treatment, percentages of CD4+ T cells, CD4+ CD28+ T cells, and CD8+ CD28+ T cells increased (P < 0.05, P < 0.01), while the percentage of CD8+ CD38+ T cells decreased (P < 0.01). More significantly, these changes were greater in the integrative medicine treatment group than in the Western medicine treatment group (P < 0.05).

CONCLUSIONSDisarranged cellular immune functions existed in acute virus infection patients. CQG could significantly improve viral infection induced immunologic derangement and immunologic injury.

OBJECTIVETo study the effects of Naoxintong Capsule (NC) on the inflammation and long-term prognosis in the borderline lesion coronary heart disease patients.

METHODSA total of 240 coronary heart disease patients with angina symptoms and accompanied with borderline lesion coronary heart disease (with the diameter stenosis in critical 50% -70%) by means of coronary angiography or multislice computed tomography coronary angiography were recruited. These patients were randomly assigned to the conventional treatment group (including nitrate, beta blockers, anti-platelet, anticoagulation, angiotensin converting enzyme inhibitors, and so on) and the NC treatment group (treated the same way as those for the conventional treatment group and NC). All patients were treated for 12 months. The occurrence of cardiovascular events was observed after treatment. The inflammatory factors in serum [interleukin 6 (IL-6), tumor necrosis factor alpha (TNF-alpha), and high sensitive C reaction protein (hs-CRP)], matrix metalloproteinases-9 (MMP-9), blood lipids and blood sugar, liver and kidney functions were measured before and after treatment.

RESULTSAfter 12 months of treatment, the incidence of angina pectoris patients (6.67% vs 15.83%, P < 0.05) and hospitalization due to acute coronary syndrome (ACS) attacks (4.17% vs 10.83%) was significantly lower in the NC treatment group than in the conventional treatment group. There was no statistical difference in the serum levels of IL-6, TNF-alpha, hs-CRP, and MMP-9 between the two groups before treatment (P > 0.05). After 12 months of treatment, serum levels of IL-6, TNF-alpha, hs-CRP, and MMP-9 were significantly lower when compared with before treatment in the same group (P < 0.05). Besides, the serum levels of IL-6, TNF-alpha, hs-CRP, and MMP-9 were significantly lower in the NC group than in the conventional treatment group (P < 0.05). By means of Logistic regression analysis we found that the post-treatment MMP-9 level and IL-6 level were independent risk factors influencing the recurrence of angina pectoris.

CONCLUSIONSNC could alleviate the inflammation. Long-term administration of NC could reduce the recurrence of angina pectoris and decrease the incidence of ACS attack in borderline lesion coronary heart disease patients. The post-treatment MMP-9 level and IL-6 level were independent risk factors influencing the recurrence of angina pectoris.

OBJECTIVESTo study the relationship between the mutation of Leu60Val in HBV core region and the cellular immunity in patients with chronic hepatitis B (CHB).

METHODSHBV DNA C gene mutation was confirmed by polymerase chain reaction (PCR) and sequencing the products directly. The cytokines (IFN-gamma, TNF-alpha and IL-2) levels in serum were measured by enzyme linked immunosorbent assay (ELISA). The distribution of T-lymphocyte subpopulations in peripheral blood was detected by flow cytometry (FCM).

RESULTSThe mutation of Leu60Val was found in 19 out of the 91 CHB patients. With the CHB severity, the mutation rate was getting higher, especially in the severe hepatitis group. The IFN-gamma and TNF-alpha levels were much higher in mutant strain group than those in wild strain group (t=2.584, 4.766, P<0.01), so was the ratio of CD4+/CD8+ (t=2.275, P<0.05).

CONCLUSIONThe mutant strain of 60Val may increase affinity to HLA-I molecule, or up-regulate the expression of HLA-I molecule, resulting in the activation of CTL to release the cytokines and cause immune response in liver.

With the development of various laboratory testing techniques such as serum calcium and parathyroid hormone (PTH) , a large number of asymptomatic or normocalcemic primary hyperparathyroidism (PHPT) can be diagnosed early. PHPT has become the third most common endocrine disease affecting human health. Currently, most PHPT, especially normocalcemic primary hyperparathyroidism, are not primary diseases and may be related to vitamin D deficiency/insufficiency and/or insufficient calcium supplementation. That is, the relative hypocalcemia caused by long-term vitamin D deficiency/insufficiency and/or insufficient calcium supplementation leads to parathyroid hyperfunction, stimulates parathyroid hyperplasia, and secretes excessive parathyroid hormone to compensate for the regulation of calcium and phosphorus balance. When it is in the initial reversible stage, it can be cured by internal medicine; if it progresses freely, long-term hypocalcemia stimulation will lead to excessive parathyroid hyperplasia and even tumor occurrence with the formation of so-called PHPT and parathyroidectomy has to be performed. Therefore, routine screening of bone mineral density, calcium, magnesium, phosphours, 25-hydroxyvitamin D, parathyroid hormone and other bone metabolism indicators in the physical examination of general population is beneficial to the prevention and treatment of bone metabolism diseases, urinary stones and hyperparathyroidism. At the same time, attention should be paid to identifying the stage of prehyperparathyroidism in which vitamin D deficiency/insufficiency and insufficient calcium supplementation will stimulate parathyroid hyperfunction. Active intervention on prehyperparathyroidism is an effective way to avoid the development of primary hyperparathyroidism.

OBJECTIVETo study the relationship between HBeAg expression and HBV-DNA in serum and peripheral blood mononuclear cells (PBMCs).

METHODS208 patients with chronic hepatitis B were included in this present study. HBV-DNA in the PBMCs were performed by polymerase chain reaction (PCR), with the serum HBV-DNA level being determined by the way of fluoresces quantities PCR (FQ-PCR). Meanwhile, HBV-GM was also detected via enzyme-linked immunosorbent assay (ELISA).

RESULTSThere were 106 patients for positivity in the HBV-DNA level of PBMCs with 102 for negativity, in which the HBV-DNA high levels (HBV DNA load > or = 1.0E5) in serum were 91.5%, 45.1% (chi2=52.12, P>0.01) respectively, with 76.4% and 50.9% (chi2=21.55, P>0.01) for the positive percentage of HBeAg expression.

CONCLUSIONA significantly positive correlation was found between HBV-DNA in PBMCs and serum HBV-DNA along with the positive percentage of HBeAg, indicating that obvious PBMCs' increase infected by HBV in patients with positivity of HBeAg and high level of serum HBV-DNA.

OBJECTIVE: To compare the iterative decomposition of water and fat with echo asymmetry and the least-squares estimation (IDEAL) method with a fat-saturated T2-weighted (T2W) fast recovery fast spin-echo (FRFSE) imaging of the spine. MATERIALS AND METHODS: Images acquired at 3.0 Tesla (T) in 35 patients with different spine lesions using fat-saturated T2W FRFSE imaging were compared with T2W IDEAL FRFSE images. Signal-to-noise ratio (SNR)-efficiencies measurements were made in the vertebral bodies and spinal cord in the mid-sagittal plane or nearest to the mid-sagittal plane. Images were scored with the consensus of two experienced radiologists on a four-point grading scale for fat suppression and overall image quality. Statistical analysis of SNR-efficiency, fat suppression and image quality scores was performed with a paired Student's t test and Wilcoxon's signed rank test. RESULTS: Signal-to-noise ratio-efficiency for both vertebral body and spinal cord was higher with T2W IDEAL FRFSE imaging (p < 0.05) than with T2W FRFSE imaging. T2W IDEAL FRFSE demonstrated superior fat suppression (p < 0.01) and image quality (p < 0.01) compared to fat-saturated T2W FRFSE. CONCLUSION: As compared with fat-saturated T2W FRFSE, IDEAL can provide a higher image quality, higher SNR-efficiency, and consistent, robust and uniform fat suppression. T2W IDEAL FRFSE is a promising technique for MR imaging of the spine at 3.0T.

Objective To study the proliferative inhibition and apoptosis promoting activity of oxymatrine on human lung cancer cells (A549) and human hepatocellular carcinoma cells (HepG-2) in vitro,and make a comparison.Methods Effect of oxymatrine on the proliferation activity of two kinds of tumor cells were compared by MTT method and growth curve method.HE staining,Hoechst 33258 fluorescent staining and transmission electron microscopy were used to compare morphological changes.Results MTr results showed that,compared with control group,the survival rate of oxymatrine 200,400,and 800 μg/mL concentration group in A549 and HepG-2 cells decreased significantly (P ＜ 0.05,0.01),half inhibitory concentration (IC50) were 1055.45 and 774.11 g/mL respectively;The growth curve showed that,compared with control group,the number of cells in oxymatrine group of HepG-2 cells cultured for fourth and fifth day and A549 cells cultured for fifth day decreased significantly (P ＜ 0.05,0.01).Oxymatrine affected morphological changes of HepG-2 cells more significantly than A549 cells.The number of cells in the oxymatrine group was significantly reduced;And the cell villi was decreased,the nucleus was small and round,and the cell apoptosis morphological characteristics were obvious.Conclusion Oxymatrine can inhibit the proliferation cells and promote the apoptosis of tumor cells.It affected HepG-2 cells more obviously,which suggests that it may have different sensitivity to different tumor cells.

Objective To investigate the dynamics and development trends of drinking water type of endemic fluorosis after water improvement in Xinbaerhuyouqi of Hulunbeir city, Inner Mongolia and to provide a scientific evidence for the development of countermeasures. Methods We mainly selected Adunchulusumu and Kerlunsumu in Xinbaerhuyouqi of Hulunbeir city as the two monitoring points after water improvement in 2000 -2009. Of these, 1 sample of centralized water supply source water and 3 samples of tap water and 5 samples of noncentralized water supply source water according to water well locations of east, west, south, north and center were collected and the levels of water fluoride were tested; the prevalence of dental fluorosis of school children aged 8 to 12 were examined; from 2002 onwards, the urine samples of 30 children aged 8 to 12(five age groups, six urine samples for each age group) were collected, and all urine samples were collected in the case of less than 30, and urine fluoride was tested. Dental fluorosis was diagnosed using Dean method; water fluoride was tested using fluoride ion selective electrode(WS/T 106-1999); urinary fluoride was tested by determination of fluoride in urine using ion-selective electrode(WS/T 89-1996). Results In 2000 - 2009, the mean levels of fluorine in drinking water in Adunchulusumu and Kerlunsumu were 1.79 - 4.35 mg/L and 1.38 - 3.18 mg/L, respectively; the detection rate of dental fluorosis of children aged 8 to 12 were 45.24％(19/42) - 89.78％(123/137) and 40.00％ (28/70) - 74.47％ (70/94), respectively; the median urinary fluoride of them were 2.30 - 4.15 mg/L and 2.73 - 4.55 mg/L, respectively. ConclusionsThe detection rate of children's dental fluorosis remains high in Xinbaerhuyouqi during the past 10 years after changing water. The endemic fluorosis remains a serious disease. Effective prevention and control measures must be taken to control the occurrence of fluorosis in the future.
