Objective To analyse effect of different dose of sustained-release theophyline on prealbumin, C-reactive protein and white blood cell count in patients with pediatric asthma.Methods 58 children with acute asthma attack in our hospital were collected.All children were randomly divided into high dose group and low dose group,29 cases in each group.On the basis of conventional treatment, high dose group were treated with high dose theophylline sustained release tablets 5 mg/kg, one times per eight hours,orally,and low dose group was treated with low dose theophylline sustained release tablets,2 mg/kg, one times per eight hours,orally.Two groups were treatment for two weeks.After the treatment, the serum levels of pre albumin, C-reactive protein and veinal blood level of white blood cell count were detected in all children.Results Compared with high dose group post-treatment, the serum level PA was higher in low dose group (P<0.05);the serum level of CRP was lower in low dose group (P<0.05);the veinal blood level of WBC, percentage of neutrophils and percentage of eosinophils was lower in low dose group (P<0.05) .Conclusion Compared with high dose of sustained-release theophyline,the low dose of sustained-release theophyline can significantly reduce the serum CRP level and veinal blood level of WBC, percentage of neutrophils and percentage of eosinophils, improve serum PA level in patients with pediatric asthma, reduce inflammation in patients.

Monascus-fermented rice is a natural food and traditional Chinese medicine. Besides its wellknown effectiveness in lowering blood lipids, Monascus-fermented rice is also beneficial for decreasing blood pressure, preventing osteoporosis, and lowering blood sugar. This article reviews recent advances in its non-anti-hyperlipemic effects and their potential mechanisms.

Alpha-lipoic acid is a potent antioxidant.Its protective effects on oxidative stress induced by diabetes and othe factors are mainly achieved via its antioxidant property.Such effects have been observed in cardiovascular system,kidney,and liver.This article reviews the recent advances in the anti-oxidation mechanisms and protective effects of alpha-lipoic acid in peripheral organs.

Objective To give nutritional evaluation in diabetic patients.Methods The human body measurements,biochemical tests,NSR2002 of 109 patients with diabetes mellitus were used for nutritional assessment and risk screening,and were analyzed for its clinical application.Results Diabetes prevalence rate of malnutrition assessed by NRS2002 was 17.4%.Low birth weight assessed by BMI was 4.6%.BMI of patients with diabetes and normal nutrition was higher than normal value,and there was a significant difference(P

0.05).CONCLUSION:The critical twinkle visual frequency of red light in normal persons is higher than that in schizophrenia patients and alcoholism patients.And the critical twinkle visual frequency in alcoholism patients is a little lower than that in schizophrenia patients.

We compared the results of heating the joint and of applying the Hot-spike and electric stimulus to the YUSEN and SANINKO points to disperse the fluid at the Knee.
The tests with the points resulted in little change in the fluid level at the Knee.
This time we measured the circumference of the Knee. A therapist established the standard measuring method, and tried to make the error decrease.
While they were observing the circumference of the Knee, they would not allow anyother medical treatments or any movement by the patient.

BACKGROUND:Mesenchymal stem cel s as potential seeded cel s have been widely used in tissue engineering and clinic therapy;thus, the precise, safe, effective isolation of mesenchymal stem cel s is the particular important premise to build culture system.
OBJECTIVE:To review the methods of isolating mesenchymal stem cel s and to compare the merit and demerit of different methods, thereby providing theoretical basis for safe and high-effective isolation of mesenchymal stem cel s.
METHODS:A computer-based online research of CNKI and PubMed databases was performed to col ect articles, which included reviews, clinical trials and experiments, published between 1965 and 2014 with the key words of“mesenchymal stem cel s (MSCs), isolation methods”in Chinese and English. A total of 52 articles were included according inclusion and exclusion criteria
RESULTS AND CONCLUSION:(1) The whole bone marrow culture method can derive a mass of mesenchymal stem cel s, which need to be purified. (2) The density gradient centrifugation method which uses the media with the density of 1.073 g/mL can be used to harvest more purified cel s. (3) The tissue digestion method is suitable for digestion and isolation of adipose tissue and umbilical cord tissue. Type II col agenase digestion is better, but they are both limited by a high demand for operative techniques. (4) Immunomagnetic bead separation is appropriate to study the biological characteristics of a kind of subpopulation of mesenchymal stem cel s which express special surface markers. (5) The combination method is also an optimal way. (6) Some new methods limited by few dates require further studies.

Objective To investigate the expression of osteopontin in colorectal cancer and hepatic metastatic cancer and its clinical significance.Methods The expression of osteopontin in 76 cases of colorectal cancer tissues,30 para carcinoma normal mucosa,liver metastatic tumor tissues in 16 patients was examined by immunohistochemical SP staining method.Results The expression rates of osteopontin in normal mucosa,colorectal cancer tissues and liver metastatic cancer tissues were 6.7％ (2/30),69.7％ (53/76),75.0％ (12/16) respectively.The expression rates of osteopontinin colorectal cancer and liver metastatic cancer was significantly higher than those in the normal mucosa (respectively x2 =34.273,23.014,all P ＜ 0.001).The expression of osteopontin was related to infiltration depth,lymph node metastasis,and distant metastasis (respectively x2 =14.347,6.577,7.278,5.537,all P ＜ 0.05).There was no significant difference in the sex and age.Kaplan-Meier survival analysis showed that patients with osteopontin positive had poor prognosis compared with osteopontin negative patients (P ＜ 0.001).Conclusions The expression of osteopontin is closely related to the invasion and metastasis of colorectal carcinoma,a hopeful indicator for the prognosis of colorectal cancer.

BACKGROUND:In previous studies, it is satisfied to sorting bone marrow mesenchymal stem cels based on natural sedimentation combined with low permeation. Then, based on particle hydromechanics theory, the settling velocity of bone marrow mesenchymal stem cels in culture liquid is calculated. A simple and easy method of separation, purification and proliferation of bone marrow mesenchymal stem cels is established by natural sedimentation velocity. OBJECTIVE:To explore the feasibility of sorting bone marrow mesenchymal stem cels by natural sedimentation velocity method. METHODS:The density interval of rabbit bone marrow mesenchymal stemcels (ρ1) was determined by density gradient centrifugation method. The diameter of rabbit bone marrow mesenchymal stem cels (d) was measured by scanning electron microscope. The density of culture liquid (ρ2) was measured by liquid density meter. The viscosity of the culture liquid (μ) was measured by viscosity meter. The settling velocity of bone marrow mesenchymal stem cels (Vt) was derived from the above four numerical values with the appropriate formula. Bone marrow mesenchymal stem cels were sorted from bone marrow tissue by natural sedimentation velocity method. Cel proliferation, purity and differentiation were observed. Meanwhile, the primary culture time of three different cel sorting methods was recorded; the colony formation rate of rabbit bone marrow mesenchymal stem cels was determined. RESULTS AND CONCLUSION:(1) The diameter of rabbit bone marrow mesenchymal stem cels was (20.37±4.58) μm, and the setting velocity of rabbit bone marrow mesenchymal stem cels in the culture liquid was 50-55 mm/h. (2) Bone marrow mesenchymal stem cels could be successfuly isolated from bone marrow tissue of rabbits by the natural sedimentation velocity method, which could be induced into osteoblasts and adipocytes. (3) The natural sedimentation velocity group cost less time than the other two density gradient centrifugation groups in the primary culture stage. The colony formation rate of the natural sedimentation velocity group was higher than that of the other two groups. (4) Natural sedimentation velocity method did not impose any intervention measures for sorting cels, which maybe maximaly maintain cel viability and biological characteristics. The whole separation process was simple and safe, which may have little damage to the cels.
