1. A trial with 4 pairs of piglets (litter mates) fed a synthetic diet ba- sed on 25% purified soya protein concentrate, Danpro-A, 25% soluble ma ize starch, 14.6% glucose, 12.0% lactose, 5% soya oil and 5% lard without (diet A) or with a supplement of 0.2% DL-methionine (diet B) has been carried out. The piglets were kept individually in metabolic crates during the whole experimental time from 7 to 56 days of age. By means of bottles with lambteats they could suck their liquid diet at any time. Five to six consecutive balances were carried out with each piglet in order to measure the digestibility, metabolizability, nitrogen balances and energy metabolism (Indirect calorimetry, open-air respiration chambers).2. No significant differences were found concerning feed intake or live weight gain between the piglets on diet A or B.3. The digestibility of dry matter, organic matters, nitrogen and energy together with the metabolizability (ME/GE) were significantly lower for piglets below 4 weeks of age than above that age where a high digestibility and metabolizability of about 95% were obtained with no significant difference between diet A and B.4. The intake of nitrogen was kept relatively low (17.4% crude protein in the diets) in order to measure any differences in the nitrogen metabolism which might occur by adding methionine. With the low nitrogen intake the nitrogen retention was a linear function of digested nitrogen. No significant difference was found between diet A and B, The pooled data gave a regression of RN = -0.524 + 0.829 DN5. Energy retention in relation to total ME gave a regression coefficient of 0.436 with no significant difference between diet A and B.6. The proportion between energy gain in fat and protein was fairly constant about 1.4 during the experimental time with no significant difference between diet A and B.7. The daily maintenance requirement was found to be 575KgJ/kg0.75 with no significant difference between the diets.8. The net availability of ME for growth, Kg, was high 0.767 but the accuracy of the estimate was low with CV=14.6%.9. The hige digestibility of nitrogen, the high utilization of digested nitrogen and the high value of Kg indicate that a soya protein concentrate as Danpro-A can be used as the only protein source in a sowmilk substitute. Adding 0.2% DL-methionine to the diet has not improved the results.

Survivin is one of inhibitors of apoptosis protein family members. It is highly expressed in lung cancer. Survivin can inhibit apoptosis. Apoptosis is closely related with development and prognosis in lung cancer. Survivin and apoptosis might become breakthrough point in treatment of lung cancer.

Vitamin D binding protein ( VDBP) is a multi-functional plasma globulin which binds to the vitamin D ( VD) in the circulation system and transporting the latter to various effective organs to exert its biological functions .Studies have found that VD and its carrier VDBP are associated with the risk of various cancers such as breast cancer , prostate cancer , and colorectal cancer however , lacking sufficient epidemiological evidences so far .Furthermore , it is still controversial regarding how VD controls and affects cancer progression.In addition, studies have also demonstrated that VDBP derived macrophage-activating factor (GcMAF) is a potent lymphokine in cancer treatment .Nonetheless, the relationship between VDBP and cancer including the VDBP polymorphism, VDBP plasma concentration are still unclear; more studies are needed to further uncover its role in cancer development and progression , thus providing new evidences for cancer diagnosis, treatment, and prognosis.

Objective:To prepare dexketoprofen enteric-coated pellets and explore the drug release rate respectively in 0. 1 mol· L-1 hydrochloric acid and phosphate buffered saline(PBS,pH 6. 8). Methods:Dexketoprofen enteric-coated pellets were prepared u-sing fluid-bed coating technology, the blank sugar pellets were coated with drug layer, isolation layer and enteric layer in order. Drug-loading rate as the index, the optimal concentrations of HPMC and drug were screened. Such indicators as adhesion, pellet uniform and surface color as the indices, the coating process was optimized by orthogonal experiment. Drug release in PBS of the enteric-coated pel-lets and the common enteric-coated tablets were compared. Results:The prepared pellets showed the properties of uniform drug load-ing, high drug-loading rate, complete round shape and lustrous appearance. The concentration of HPMC and drug was 5% and 15%, respectively. The optimal coating process was as follows:the material temperature was 36℃, the atomization pressure was 1. 0 bar and the airbrush rate was 0. 8 ml·min-1 . The drug release of the pellets in hydrochloric acid was below 10% in 2 hours, while the release in PBS was greater than that of the common enteric-coated tablets. Conclusion: The prepared enteric-coated pellets are feasible in technology, and exhibit satisfactory acid endurance and drug release in vitro.

Kupffer cells, the resident macrophages of the liver, play an important role in ischemia/reperfusion(L/R)injury in liver transplantation. 1schemic liver is reperfused through portal vein, and then Kupffer cells are activated. The liver is damaged by the released reactive oxygen species, inflammatory mediators and cytokines. On the other hand, upregulation of HO-1, induced by the activated kupffer cells, exerts a cytoprotective function for the IYR injury in liver transplantation models. Thus, Kupffer cells play the dual role on L/R injury in liver transplantation.

Objective To evaluate lipoprotein lipase (LPL) activity and its relationship to serum lipid. Methods Serum triglyceride (TG) ,total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C) and postheparin LPL activity in 40 elderly subjects and 45 subjects in control group. Results TG,TC and LDL-C levels were much higher in the elderly than in control group (P <0.05 orP <0.01) ;postheparin LPL activity was lower in elderly (P <0.05) ; and showed a negative correlation with serum TG level (r = -0. 513 ,P < 0.01), but was positively correlated with serum HDL-C concentration (r = 0. 390, P < 0.05). Conclusion The decreased activity of LPL in the elderly may contribute to hypertriglyceridemia associated with low level of high density lipoprotein cholesterol, and could be a risk factor for atherosclerosis.

BACKGROUND:Body mass is a critical factor affecting plantar pressure,and the systematic study on plantar pressure with different body mass has not been reported.OBJECTIVE:To measure the plantar pressure of normal people with different body weight,so as to provide reference for the application of plantar pressure.METHODS:Totally 80 healthy people with different body weight were enrolled,and the dynamic plantar pressure was measured by the Footscan 2 meter flat foot pressure distribution system (RSscan,Belgium).The participants were divided into four groups (n=20 per group) according to the classification criteria for prevention and control of overweight and obesity in Chinese adults,such as underweight,normal weight,overweight group,and obesity groups,and a comparative analysis was conducted.RESULTS AND CONCLUSION:(1) The peak pressure and impulse of each region of the foot were significantly increased with body mass index increasing (P ＜ 0.05).Compared with the normal weight people,the pressure of the part foot area of the overweight subjects and each part foot area of the obese subjects were significantly increased (P ＜ 0.05).(2) The percentage of the medial plantar contact area accounting the total contact area of the foot was significantly increased with body mass index increasing (P ＜ 0.01);the percentage in the obese group was significantly higher than that in the normal group (P ＜ 0.05).(3) These results show that the plantar pressure and impulse are increased in overweight and obese subjects due to weight gain,and foot will appear with pathological changes with time going.Obese people suffer from arch drop due to weight gain,and increase in contact area of midfoot,which are easy to cause flatfoot.Overweight especially obese,should pay attention to control weight,do appropriate exercise,wear suitable shoes,protect the foot,further to prevent the occurrence of foot injury and flatfoot.
