OBJECTIVETo understand the levels of total physical activities among different populations, and the distribution of four domains.

METHODSWith proportional stratified sampling and cluster sampling method, 3555 subjects were selected including officials, company staff, high school students, community population and floating population.

RESULTSThe proportions for inactive, insufficiently active, minimally active and health enhancing physical active (HEPA active) as a whole were 20.5%, 10.1%, 26.5% and 42.9% respectively. Community population had the highest level of HEPA active which was 65.6%. Floating population had the highest level of inactivity of 33.1%. Apart from the male floating population, the active level in transportation, physical activity among the investigated were the highest compared to other three active domains. Leisure-time physical activity was in the opposite.

CONCLUSIONThe type of physical activities among general citizens were mainly of physical activity related to transportation but less leisure-time physical activity was seen. Floating population had the highest level of both HEPA activity and inactivity.

The dosage-efficacy/toxicity relationship of the 50% alcohol extracts of Polygonum multiflorum was comparatively investigated on either normal or CCl4-induced chronic liver injury rats, by determining the general condition, serum biochemical indices and liver histopathology, coupled with the factor analysis. The dosages were 10 and 20 g raw materials per kg body weight. Compared with the normal control group, the normal high dose group showed significant increases of the serum alanine transaminase (ALT), total bilirubin (TBIL), high mobility group box 1 (HMGB-1) and interleukin-1β (IL-1β) (P < 0.05 or P < 0.01), as well the frequent incidences of inflammatory cell infiltration, hepatic sinus enlargement and fiber stripes formation in histopathological sections. Compared with the model control group, the model low dose group showed significant declines of serum ALT, aspartate transaminase (AST) and total bile acid (TBA) (P < 0.05), as well the alleviation of vacuoles of hepatocytes, but no amelioration of the inflammatory cell infiltration and fibrous tissue hyperplasia; moreover, the model high dose group showed significant degeneration declines of serum HMGB-1, tumor necrosis factor-α (TNF-α) and IL-1β (P < 0.05, P < 0.01), as well the evident alleviation of vacuoles degeneration of hepatocytes, inflammatory cells infiltration and fibrosis degree. The factor analysis showed that the low dosage treatment had almost neither injuring effect on the normal rats nor protective effect on the model rats; while the high dosage treatment showed observable injuring effect on the normal rats, expressed by the significant increases of the factor-1 (HMGB-1, TNF-α and IL-1β as the main contributors) and factor-2 (TBIL, ALT and TBA as the main contributors) relative to the normal control group. The liver protective effect of the high dosage treatment could be observed with the significant reduction of the factor-1, indicating the effective alleviation of the expression of inflammatory cytokines. In conclusion, it could illustrated the phenomenon of symptom-based prescription theory of Polygonum multiflorum on rat livers: the high dosage of the herb had either an injuring effect on normal rats, or a therapeutic effect on the rats with chronic liver injury.

OBJECTIVETo compare the bidirectional effect of rhubarb total anthraquinone (TA) and total tannins (TT) on rats' liver.

METHODSOne hundred rats were randomly divided into 10 groups, i.e., the blank group, the model group, the blank + high dose TA group, the blank +low dose TA group, the blank + high dose TT group, the blank + low dose TT group, the model + high dose TA group, the model + low dose TA group, the model +high dose TT group, and the model + low dose TT group, 10 in each group. The carbon tetrachloride (CCI4) was used to prepare the acute liver injury rat model. TA and TT of rhubarb (at 5.40 g crude drugs/kg and 14.69 g crude drugs/kg) were intragastrically administrated to rats in all groups except the blank group and the model group, once daily for 6 successive days.The general state of rats, biochemical indices such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), laminin (LN), hyaluronic acid (HA), transforming growth factor beta1 (TGF-beta1), as well pathological results of rat liver tissues. Finally the protection laws of TA and TT for rats' liver were analyzed using factor analysis.

RESULTSCompared with the blank control group, all biochemical indices increased in the blank group (P < 0.05, P < 0.01). HA also increased in the blank + high dose TA group; AST, ALT, and HA also increased in the blank +high dose TT group (P < 0.05). Compared with the model group, AST, ALT, ALP, HA, and TGF-beta1 significantly decreased in the model + low dose TA group, the model + high dose TA group, the model + low dose TT group (P < 0.05, P < 0.01). Serum AST, ALT, and ALP also decreased in the model + high dose TT group (P < 0.05, P < 0.01). Pathological results showed that mild swollen liver cells in the model + high dose TA group. Fatty degeneration and fragmental necrosis around the central veins occurred in the blank + high dose TA group. The pathological injury was inproved in the model +low dose TA group. Two common factors, liver fibrosis and liver cell injury, were extracted by using factor analysis. TA showed stronger improvement of the two common factors than TT.

CONCLUSIONSRhubarb TA and TT showed protective and harmful effects on rats' liver. At an equivalent dosage, TA had better liver protection than TT. High dose TT played a role in liver injury to some extent.

To observe the characteristics of primary biliary cirrhosis (PBC) with a suboptimal biochemical response to ursodeoxycholic acid. A total of 38 Chinse PBC patients (5 male patients, 33 female patients, average age 55 years old) with treatment of ursodeoxycholic acid in our hospital from January 1999 to January 2009 were erolled and studied retrospectively. 17 suboptimal biochemical responders mainly presented with liver diseases related symptoms including jaundice (41.1%), fatigue, anorexia (23.5%), edema and abdominal distension (11.7%). 21 good biochemical responders mainly presented with abnormal liver function tests without symptoms. The suboptimal biochemical responders had significantly higher baseline levels of total serum bilirubin, alkaline phosphatase, alanine aminotransferase, aspartate aminotransferase, immunoglobulin G and globulin as compared to the good biochemical responsers. There were no differences in gender, age and the dose of UDCA. PBC patients with liver diseases related symptoms, marked abnormal liver tests and characteristics of autoimmune hepatitis may have a suboptimal biochemical response to ursodeoxycholic acid treatment.

OBJECTIVEClinical features of 30 cases of amyloidosis, a rare disease in China, were analyzed in order to improve the recognition of the disease here.

METHODS30 cases of biopsy-proven amyloidosis, admitted to Beijing Friendship Hospital from July 1980 to December 2003 were retrospectively reviewed.

RESULTS12 of the 30 cases were systemic amyloidosis. Among them 9 were primary amyloidosis, 1 secondary amyloidosis and 2 familial amyloid polyneuropathy. The other 18 cases were localized amyloidosis. Males (17) were more than females (13). In the 12 primary amyloidosis patients, kidney (75.00%), liver (58.33%), peripheral nervous system (58.33%) and heart (50.00%) were most commonly involved. Nonspecific symptoms such as fatigue, weight loss, hepatomegaly, limb numbness, edema and heavy albuminuria were the most common clinical manifestations. Localized amyloidosis involved only one organ, such as skin, alimentary tract and nasopharynx without evidences of a systemic disease. Excision of the localized amyloid deposits was performed in 13 cases.

CONCLUSIONSystemic amyloidosis usually involves multiple organs and systems, leading to highly variable clinical manifestations. An increase in the vigilance of the awareness of this disease among clinicians will improve the possibilities for its diagnosis.

OBJECTIVETo investigate the effect of phosphatidylinositol 3-kinase inhibitor LY294002 combined with NF-κB P65 nuclear translocation inhibitor SN50 on the tumor cell growth and apoptosis using a nude mouse model of gastric cancer.

METHODSHuman gastric cancer cell strain SGC7901 was transplanted subcutaneously to nude mice to establish tumor models. Model mice were randomly divided into the control group, the LY294002 treatment group, the SN50 treatment group, and the LY294002+SN50 treatment group, with 5 in each group. After being treated for 10 days, the inhibition rate of tumor growth was ascertained by measuring the size of tumor. Immunohistochemical method was used to detect the expression levels of Bcl-2, P53 and Bax proteins and transmission electron microscopy to investigate the apoptosis of tumor cells.

RESULTSOn the 10th day after treatment, the inhibition rate of gastric cancer cellular growth in the LY294002+SN50 group was (49.2±2.5)%, which was significantly higher than that in the LY294002 group(29.4±1.5)% and SN50 group (19.7±1.6)%(P<0.05). In comparison with the other two groups, LY294002+SN50 group exhibited more severe apoptosis, with expression of Bcl-2 decreased and that of P53 and Bax increased more significantly(P<0.05).

CONCLUSIONLY294002 combined with SN50 inhibits the growth of SGC7901 transplanted tumor and aggravates the apoptosis of gastric cancer cells in nude mice model.
