OBJECTIVETo observe the dynamic time-phase expressions of key genes of brain-gut CaM signal pathway of spleen Qi deficiency rats and the intervention effect of Sijunzi decoction.

METHODMale Wistar rats were randomly divided into the normal control group, model 14 d, 21 d, 28 d groups, and Sijunzi decoction 14 d, 21 d, 28 d groups. Except for the normal control group, the remaining groups were included into the spleen Qi deficiency model with the bitter cold breaking Qi method (ig 7.5 g · kg⁻¹ · d⁻¹ of Rheum officinale, Fructus aurantii immaturus, Magnolia officinalis preparation) and the exhaustive swimming method. On the 7th day after the modeling, the Sijunzi decoction groups were orally administered with Sijunzi decoction 20 g · kg⁻¹ · d⁻¹. The expressions of key genes CaM/CaMK II of CaM signaling pathway in hippocampus and intestine at different time points by immunohistochemical method and Western blot. At the same time, the intervention effect of Sijunzi decoction on spleen Qi deficiency rats and its mechanism were analyzed.

RESULTSpleen Qi deficiency rats showed higher intestinal CaM/CaMK II expression and lower hippocampus CaM/CaMK II expression than normal rats (P < 0.05, P < 0.01). After the treatment of Sijunzi decoction, spleen Qi deficiency rats showed reduction in intestinal CaM/CaMK II expression and increase in hippocampus CaM/CaMK II expression (P < 0.05, P < 0.01).

CONCLUSIONThe formation of spleen Qi deficiency syndrome may be related to the high expression of CaM/CaMK II in small intestine tissues and its low expression in hippocampus tissues. Sijunzi decoction may achieve the therapeutic effect in spleen Qi deficiency syndrome by reducing the CaM/CaMK II expression in intestinal tissues and increasing it in hippocampus tissues.

OBJECTIVESevere acute respiratory syndrome (SARS) is an emerging infectious disease that first manifested in humans in November 2002. The SARS-associated coronavirus (SARS-CoV) has been identified as the causal agent, but the pathology and pathogenesis are still not quite clear.

METHODSPost-mortem lung samples from six patients who died from SARS from April to July 2003 were studied by light and electron microscopy, Masson trichromal staining and immunohistochemistry. Evidence of infection with the SARS-CoV was determined by reverse-transcription PCR (RT-PCR) , serological examination and electron microscopy.

RESULTSFour of six patients had serological and RT-PCR evidence of recent infection of SARS-CoV. Morphologic changes are summarized as follows: (1) Diffuse and bilateral lung consolidation was seen in all patients (6/6) with increasing lung weight. (2) Diffuse alveolar damage was universal (6/6) with hyaline membrane formation (6/6), intra-alveolar edema/hemorrhage (6/6), fibrin deposition (6/6), pneumocyte desquamation (6/6). A marked disruption in the integrity of the alveolar epithelium was confirmed by immunostaining for the epithelial marker AE1/AE3 (6/6). (3) Type II pneumocytes, with mild hyperplasia, atypia, cytomegaly with granular amphophilic cytoplasm and intracytoplasmic lipid accumulation (5/6). (4) Giant cells in the alveoli were seen in five of 6 patients (5/6) , most of which were positive for the epithelial marker AE1/AE3 (5/6), but some cells were positive for the macrophage marker CD68(2/6). (5) A pronounced increase of macrophages were seen in the alveoli and the interstitium of the lung (6/6), which was confirmed by histological study and immunohistochemistry. (6) Haemophagocytosis was present in five of the 6 patients(5/6). (7) Lung fibrosis was seen in five patients(5/6), with alveolar septa and interstitium thickening(5/6), intraalveolar organizing exudates (6/6) and pleura thickening (4/6). Proliferation of collagen was confirmed by Masson trichromal staining, most of which was type III collagen by immunostaining. The formation of distinctive fibroblast/myofibroblast foci was seen in five patients (5/6) by light microscopy and immunochemistry. (8) Squamous metaplasia of bronchial mucosa was seen in five patients(5/6). (9) Thrombi was seen in all patients(6/6). (10) Accompanying infection was present in two patients, one was bacteria, the other was fungus. In addition, electron microscopy revealed viral particles in the cytoplasm of alveolar epithelial cells and endothelial cells corresponding to coronavirus.

CONCLUSIONDirect injury of SARS-CoV on alveolar epithelium, prominent macrophage infiltration and distinctive fibroblast/myofibroblast proliferation may play major roles in the pathogenesis of SARS.

BACKGROUNDThere are no reports on the association between perinatal characteristics and comprehensive physical function in Chinese elderly people. In this study, we traced 875 subjects who were born at the Peking Union Medical College Hospital (PUMCH) of China from 1921 to 1941. The purpose of this study was to determine the effects of perinatal characteristics on activities of daily living (ADL) function in the geriatric period.

METHODSBirth data of 875 subjects were obtained from obstetric birth records of PUMCH. Adulthood data collection was conducted in the outpatient clinics of PUMCH. During the clinic visits, trained research staff administered physical examinations, activities of daily living scale and a demographic questionnaire. ADLs of all subjects were assessed with the activities of daily living scale.

RESULTSThere were 101 subjects whose ADL function was limited and the rate of ADL limitation was 11.5%. Binary logistic regression analyses results showed that the main influencing factors of ADL were age, maternal age at birth, occupation, daily exercise and chronic disease. Subjects whose maternal age at their birth exceeded 35 years were at 2.202 times (1.188 - 4.083) greater risk of ADL limitation when we applied multivariate logistic regression models.

CONCLUSIONSThis study validated the relationship between perinatal characteristics and ADL in the geriatric period. An older maternal age at birth could predict a higher ADL limitation rate in the geriatric period.

Lipid accumulation in the vessel wall and tunica intima vasorum pathological changes are important factors in the development of atherosclerosis, which are closely related with hemodynamics. In this paper, we established a model of local low shear stress in rabbits using carotid artery cannula and a high cholesterol diet for 2 weeks, 4 weeks and 8 weeks. The effects of Shenlian extract on blood flow, vascular pathology formation and lipid metabolism were assessed by electromagnetic blood flow meter and hematoxylin-eosin staining of the proximal end in carotid artery at different times. The results demonstrate that the relationship between blood flow and shear stress for control, atorvastatin, Shenlian extract high-dose, Shenlian extract middle-dose, and Shenlian extract low-dose were linearly related. The blood flow and the shear stress of proximal end in carotid artery of Shenlian extract (1.12, 2.24, 4.48 g x kg(-1)), and atorvastatin (4.7 x 10(-4) g x kg(-1)) were significantly (P < 0.05)increased compared with the control. Plasma total cholesterol (TC), low density lipoprotein cholesterol (LDL-C) ,and high density lipoprotein cholesterol (HDL-C) were markedly decreased with the increasing of dose and time. This study is the first to prove that the inhibition of Shenlian extract on low shear stress (LSS) induces rabbits carotid atherosclerosis with increasing blood flow and decreasing lipids and vessel pathological changes.

OBJECTIVE: To investigate the effects of Radix Angelicae Sinensis (RASI) and hydrocortisone combination on the murine asthma model and the mechanism. METHODS: BALB/c mice were randomly divided into control group, blood stasis model group, asthma model group, HSS group, RASI group and RASI+HSS group (=12). Ovalbumin (OVA) was used to replicate mice asthma model and hydrocortisone sodium succinate (HSS) to copy blood stasis model. Effects of RASI, HSS and their combination on hemorheology, anti-asthma (asthmatic behaviors, lung function, lung index and water content in lung tissue) were observed. and anti-asthma mechanisms The expression of relative cytokines, high-mobility group box 1 (HMGB1), toll-like receptor 4 (TLR4) and nuclear factor-κB (NF-κB) was detected by ELISA and immunohistochemistry respectively. RESULTS: Eight g/kg RASI, 0.05 g/kg HSS and their combination could significantly relieve asthma behavioral indicators, improve lung function, reduce lung index and water content in lung tissue, decrease the levels of TNF-α, IL-1β and IL-6 in broncho-alveolar lavage fluid (BALF), and inhibit the high expression of HMGB1, TLR4 and NF-κB in lung tissue. The improvement of lung function and the decrease in level of relative cytokines (TNF-α、IL-1βIL-6) were better in RASI+HSS group than those in RASI group and HSS group, and the inhibition of protein expression of TLR4 and NF-κB was also too. Combined administration of RASI and hydrocortisone could decrease serum thromboxane B2 (TXB2) content and blood viscosity, which were increased induced by hydrocortisone. CONCLUSIONS Combined administration of RASI and hydrocortisone have obvious anti-asthma effects and one of the mechanisms is to inhibit protein synthetization of HMGB1, TLR4 and NF-κB.The combined administration of RASI and hydrocortisone has stronger improvement of lung function than that of RASI and hydrocortisone alone, and it may be related to the inhibition of TLR4 and NF-κB synthetization. The combined administration of RASI can alleviate abnormal changes of hemorheology induced by hydrocortisone in treatment of asthma.

Objective:To investigate the effect of Huangqi Jianzhongtang on Janusprotein tyrosine kinase 2/signal transducers and transcriptional activator protein 3 (JAK2/STAT3) signal pathway in rats with spleen-stomach deficiency cold type gastric ulcer (GU). Method:A total of 60 SPF level Wistar rats were randomly divided into two groups: blank group and model group. Model rats were used to reconstruct the spleen-stomach deficiency cold type GU model by comprehensive modeling method. Model rats were divided into model group, Anweiyang group and high, medium and low-dose Huangqi Jianzhongtang groups according to the random number table, with 10 rats in each group. Rats in blank group and model group were given 10 mL·kg^-1·d^-1 distilled water, and 16, 8, 4 g·kg^-1·d^-1 Huangqi Jianzhongtang, respectively. Rats in the positive control group were given 0.14 g·kg^-1·d^-1 Anweiyang for 21 days. The gene expressions of JAK2 and STAT3 in the ulcer tissue were detected by Real-time fluorescent quantitative polymerase chain reaction (Real-time PCR), the protein expressions and phosphorylation levels of JAK2 and STAT3 in the ulcer tissue were detected by Western blot, and the contents of interleukin-10（IL-10）and interleukin-17（IL-17）in the gastric tissue of each group were detected by enzyme-linked immunosorbent assay (ELISA). Result:Compared with the blank group, the general survival condition of the model group was worse, the content of IL-10 in gastric homogenate was significantly reduced, while the content of IL-17 was significantly increased (P<0.05), the protein expressions of JAK2 and STAT3 in gastric tissue was not significantly increased, whereas the gene expressions and phosphorylation levels of JAK2 and STAT3 were significantly increased (P<0.05). Compared with the model group, the content of IL-10 increased, but the content of IL-17 decreased, the gene expressions of JAK2 and STAT3 and the level of protein phosphorylation decreased in the treatment group, especially in the high-dose Huangqi Jianzhongtang group, with statistically significant differences (P<0.05). Conclusion:Huangqi Jianzhongtang can improve the survival condition of rats with spleen stomach deficiency cold type gastric ulcer, and its mechanism may be related to the intervention of gastric mucosal immune barrier dysfunction mediated by JAK2/STAT3 pathway activation.
