Due to the irregular of diet and overfeeding greasy and surfeit flavor closely associated with hyperuricemia disease, the lipid emulsion containing high cholesterol was used to model. To obtain a more stable and sustained animal model for the efficacy evaluation of traditional Chinese herbs, we observed the influence on the serum uric acid of rat induced by the lipid emulsion compared with high purine diet. 36 SD male rats were randomized to the normal control group, high purine diet group and lipid emulsion group respectively. The general behavior, body weight and daily food intake of rats were observed. The orbital blood was taken to separate into the serum and 24 hours urine was collected. The serum indexes such as UA, BUN, Cr, ALT, AST, TC, TG, LDL-c were determined every 2 weeks, and XOD, ADA enzyme activity were determined at the 4th week. The urine indexes such as UA, Cr and Cua/Ccr were determined at the 4th week. After stopping modeling, the serum UA were determined two weeks and four weeks later respectively. At the 2nd week, the body weight and daily food intake of rats in the lipid emulsion group reduced significantly, and the level of serum UA, BUN, Cr, TC, LDL-c, ATL, AST raised significantly meanwhile TG reduced. At the 4th week, the serum UA in high purine diet group did not raise, and the serum XOD raised obviously while ADA did not; the serum UA in lipid emulsion group was higher significantly, and the serum XOD and ADA raised while Cua/Ccr reduced obviously. At the 6th weeks, the serum UA in both the high purine diet group and lipid emulsion group raised obviously. After stopping modeling, the serum UA in lipid emulsion group still maintained a high level at the 2nd week and back to the normal level at the 4th week. Compared with high purine diet, the hyperuricemia model induced by lipid emulsion forms earlierand more stable. It maybe has great value to study the pharmacodynamics of traditional Chinese medicine treatment to hyperuricemia disease. Its mechanism may be related to increasing XOD and ADA enzyme activity which can promote uric acid synthesis, meanwhile inhibiting of uric acid excretion.

OBJECTIVETo observe the effect of composite factors, like long-term high-salt & fat diet and alcohol abuse on blood viscosity and blood pressure in rats, and compare with a model induced by high molecular dextran, in order to build a chronic hyperviscosity aminal model which is similar to human hyperviscosity in clinic and lay a foundation for efficacy evaluation on traditional Chinese medicines.
METHODMale SD rats were randomly divided into the normal group, the high molecular dextran (HMD) group and the high salt & fat and alcohol (HSFA) group. The HMD group was given normal diet and water for 23 day and then 10% HMD through tail vein for 5 days. The HSFA group was fed with high salt and high fat diets every day and alcohol for 20 h x d(-1) for 13 weeks. After the modeling, whole blood viscosity and plasma viscosity were measured in the 5th, 8th and 11th week. Blood pressure was measured in the 5d, 7h, and 10th week. Red cell count (RBC) and hematocrit (HCT) were measured in the 11th week. PAgT, Fb, ET-1, NO, PGI, TXA2 contents of the normal group and the HSFA group were measured in the 13th week, and IECa21 content was measured with flow cytometry. Result: After the modeling, the HMD group was in good conditions with glossy hairs and active behaviors. The HSFA group was depressed with withered hairs and less activities. During the 5th-11th weeks, the HMD group and the HSFA group showed higher values in high and low shear whole blood viscosity (WBV) than the normal control group. The plasma viscosity (PV) of HMD rats was significantly increased only in the 5th week, and that of HSFA rats significantly increased in the 8"' and 11th week, particularly in the 11'h week. In the 111h week, the HSFA group showed significant increases in RBC and HCT. After the modeling, the blood pressure of HMD rats showed no significant changes, but the blood pressure of HSFA rats significantly increased during 7' and 101h weeks, particularly in the 10"' week. In the 13th week, PAgT, IECa2+, Fb, ET-1 of HSFA rats significantly increased, but with decreases in NO and PGI2.
CONCLUSIONLong-term high salt & fat and alcohol diets can cause abnormal blood viscosity in rats. WBV significantly increased since the 5th week in rats, and PV increased since the 8th week. The mechanism for increasing BV may be: (1) increases in RBC, HCT, and IECa2+, (2) PAgT increase, (3) Fb content increase, or (4) TXA2/PGI2, ET-1/NO imbalance. Although the modeling time with the method is longer than that with the HMD method, the model is more stable and moderate, and could lead to abnormal increases in WBV and PV; Whereas the HMD method only induced transient increase in plasma viscosity and abnormal increase in SBP. The model is more similar to traditional Chinese medicine syndromes and pathogenesis, with higher value for studies on efficacy of traditional Chinese medicines.

OBJECTIVETo evaluate the role of nutritional status on serum immunoglobulins, body weight and postoperative infectious-related complications in patients with Crohn's disease receiving perioperative parenteral nutrition (PN).
METHODS32 patients with Crohn's disease receiving perioperative parenteral nutrition in our department between 1984 and 1994 were enrolled in this survey. 16 patients with loss of body weight in the range of 15%-30% were assigned to the malnutrition group, the other 16 patients with normal weight or loss of body weight less than 15% to the control group. Serum IgM, IgG and IgA levels were measured before and after PN by enzyme-linked immunosorbent assays. Liver function, body weight changes and postoperative complications were also analyzed.
RESULTSIgM levels were elevated before PN in both groups [control group: (133 +/- 16) mg/dl, malnutrition group: (139 +/- 41) mg/dl; normal value: (110 +/- 35) mg/dl; P = 0.04], decreased to normal value [(105 +/- 29) mg/dl, P = 0.02] in the malnutrition group while having no obvious changes in the control group [(129 +/- 13) mg/dl, P = 0.34]. No significant changes in concentrations of IgG and IgA were found (P in the range of 0.20-0.57). The average weight gain was 1.862 kg in malnutrition group [before PN: (45.8 +/- 8.9) kg, after PN: (48.0 +/- 8.8) kg; P = 0.005] and no significant changes in the control group [before PN: (55.6 +/- 6.1) kg, after PN: (56.3 +/- 6.0) kg; P = 0.46]. There was an increase in infectious complications in the control group (control group: 4 cases, 25%, malnourished group: 2 cases, 12.5%; P = 0.13).
CONCLUSIONSPerioperative parenteral nutrition ameliorated the humoral immunity, increased the body weight in patients with obvious malnutrition, whereas it had little value for those without or with mild malnutrition.

Objective To investigate the predictive significance of thromboelastography ( TEG) for early neurological deterioration ( END) in patients with acute cerebral infarction. Methods This was a case-control study. From March 2016 to August 2017,a total of 195 consecutive patients with acute mild to moderate cerebral infarction (National Institute of Health stroke scale [NIHSS] score <16) within 24 h after onset were registered prospectively. The demography, clinical data, and laboratory test results were collected. The TEG examinations were completed after admission. According to whether having END or not within 3 d after admission,they were divided into either a END group (n=60) or a non-END group (n=135). A logistic regression model was established to analyze the relationship between TEG parameters and END. Results Of the 195 eligible patients,60 (30. 8%) experienced END. TEG reaction time (RT) and kinetic time ( RT) in patients of the END group were significantly less than those of the non-END group (4. 1 ± 1. 1 min vs. 4. 4 ± 1. 2 min;1. 3 ± 0. 3 min vs. 1. 5 ± 0. 4 min,t=3. 395 and 3. 093,respectively;all P<0. 01). The proportions of the shortened RT and KT in patients of the END group were significantly higher than those of the non-END group (80. 0% [48/60] vs. 63. 0% [85/135],18. 3% [11/60] vs. 8. 1% [11/135]). There were significant differences (χ2 =5. 560 and 4. 305,all P <0. 05). After adjusting for the factors of age,sex,diabetes mellitus,smoking,baseline NIHSS score,and serum hypersensitive C-reactive protein, logistic regression analysis showed that the shortened RT was independently correlated with END (OR,1. 612,95% CI 1. 094-2. 376,P=0. 016). Conclusion The shortened TEG coagulation time RT on admission has a certain predictive value for END within 3 d after onset of acute mild to moderate cerebral infarction.

[Objective]To explore the adverse pregnancy outcomes(APO)and examine the predictive value of umbil-ical artery Doppler in systemic lupus erythematosus(SLE)pregnancies.[Methods]Data of 273 pregnancies from 2010 to 2016 were analyzed retrospectively. Pulsatility index(PI),resistance index(RI),and systolic/diastolic ratio(S/D)of the umbilical artery flow velocity data were monitored by Doppler ultrasound.[Results]One or more APO occurred in 61.9% of patients with SLE,among which pregnancy loss occurred in 60 cases;preterm birth in 56 cases;intrauterine growth retardation occurred in 20 cases;and fetal distress occurred in 21 cases.Twelve of pregnancies resulted in neona-tal Lupus. In total,118 patients underwent fetal umbilical artery Doppler during 28~34 gestational weeks. Doppler PI, RI,and S/D were significantly higher in the APO groups than in the patients without APO.[Conclusion]Pregnancies in lupus still had an increased risk of APO.Umbilical artery Doppler was useful in predicting APO in lupus pregnancies.

OBJECTIVETo evaluate the relationship between mammalian target of rapamycin (mTOR) signaling pathway and histone acetylation in cell survival, cell cycle, gene expression and protein level on human gastric cancer cells.
METHODSHuman gastric cancer cell lines, MKN45 and SGC7901 were treated with trichostatin A, rapamycin and/or LY294002, a PI3K inhibitor. Cell viability was analyzed by methylthiazolyl tetrazolium. Cell cycle distribution was evaluated by flow cytometry. The transcription level of p21(WAF1) gene was detected by using real-time polymerase chain reaction. Proteins were detected by Western blotting.
RESULTSCell viability remarkably reduced after treatment by more than two drugs (P< 0.01). Through flow cytometry assessment, MKN45 cells were arrested in G2 phase (P< 0.05), while SGC7901 cells were in G2 or G1 phase (P< 0.05) whether treated with single or more than two drugs. The expression of p21(WAF1) mRNA was remarkably increased in the gastric cancer cells treated with conjoined drugs (P< 0.01). Phosphorylation of Akt, p70S6K and 4E-BP1 was significantly reduced in cells treated with conjoined drugs (P< 0.01). And histone acetylation of H4/H3 was also increased in cells treated with conjoined drugs (P< 0.01).
CONCLUSIONmTOR singnaling pathway has an important relationship with histone acetylation in gastric cancer cell lines. There is a co-effect of mTOR inhibitor and histone deacetylase inhibitor on gastric cancer cells.
