Objective:To explore the expression of LOX-1(lectin like oxidizeol low density lipoprotein receptor-1,LOX-1) in aorta of atherosclerotic rabbits and modulating the effect of fluvastatin and Shexiang baoxin pill on the gene and protein expression of LOX-1. Methods:Tirty-two New Zealand white rabbits were randomly divided into four groups: hypercholesterol diet group (fed mth high cholesterol diet),hypercholesterol diet plus Fhevastatin group(fed with high cholesterol diet plus Fhe vastain 25mgl kgld).hypercholesterol diet plus shexiang Bao xin Pill group (fed with high cholesterol diet plus shegxiang Baoxinpill 25mgl kgld).normal diet gwup(fed mith regnlar chow),the protein expression of LOX-1 in aorta of rabbits were examined by immunohistochemsthy,the gene expresswin of LOX-1 in aorte of rabbits were examined by R7-PCK. Results:hypercholesterol diet group(fed with high cholesterol diet),hypercholesterol diet plus fluvastatin group(fed with high cholesterol diet plus Fluvastatin 25mg/kg?d), hypercholesterol diet plus Shexiang baoxin pill group(fed with high cholesterol diet plus Shexiang Baoxin Pill 25mg/kg?d),normal diet group(fed with regular chow),the protein expression of LOX-1 in aorta of rabbits were examined by immunohistochemistry,the gene expression of LOX-1 in aorta of rabbits were examined by RT-PCR. Conclusion:LOX-1 was expressed in rabbit aorta of hypercholesterol diet group and two treatment groups, expression of LOX-1 in two treatment groups both significantly reduced compared with hypercholesterol diet group(P

Objective:To search for a simple and rapid method of preparating the IL-2 conjugated immunoliposomes with high conjugate rate.Methods:The IL-2 conjugated immunoliposomes were prepared by Glutaraldhyde,Undecanal or Derivatization.All methods were analyzed and compared.The conjugate rate of IL-2 was determined by Bradford Assay.Centrifugal acceleration experiment served to prove the liposome stability.Results:IL-2 conjugated liposome by shiff’s base through Undecanal didn’t cause IL-2-self or liposme-self inter-cross link,and conjugate rate was high and stability was good.Conclution:Undecanal is suggested to prepare the IL-2 conjugated immunoliposomes for the anaphase cell experiment.

Objective To explore the effect of self-made water pillow on absolute bed rest patients.Methods Eight-eight patients were randomly allocated into observation group(n=46)and control group(n=42).The patients in the control group received daily care with conventional cotton pillows which were placed at the compression part, while those in the observation group were treated with newly designed water pillows.Both groups received constant turn-over to avoid pressure sores.The two groups were compared in terms of times of daily turn-over,degree of comfort and rate of skin pressuring red.Results The time of daily turn-over in the observation group was less than that of the control group and the degree of comfort was higher and the rate of skin pressuring red smaller all with statistically significant differences(P<0.05).Conclusion The application of the self-made water pillow can effectively prevent pressure sore,enhance comfort degree of absolute bed rest patients and reduce the workload of nursery.It is simple, economical,convenient and safe.

Objective: To study the effect of Resen heche tablets (RSHC) on tonyfing and warming Shen Yang. Methods: The mice model of Shen Yang deficiency was established by injecting hydrocortisone. The body weight, autonomic activity and swimming time in ice water in model mice were observed. The level of superoxide dismutase (SOD) in red cell and lipid peroxide (LPO) in plasma of aged rats were analyzed. The effect on anti stress in mice was examined. Results: RSHC had the remarkable effect to improve body weight and autonomic activity and to prolong swimming time in ice water in model mice, and to increase SOD activity and reduce LPO in blood of aged rats, and to elevate the ability of anti fatigue and anoxic tolerance in mice. Conclusion: RSHC drug has the effect on tonifying and warming Shen Yang; can promote growth, enhance organism activity, elevate the adaptation to circumstances and protect injury from free radicals.

Genome editing is defined as highly-effective and precise modification of cellular genome in a large scale. In recent years, such genome-editing methods have been rapidly developed in the field of industrial strain improvement. The quickly-updating methods thoroughly change the old mode of inefficient genetic modification, which is "one modification, one selection marker, and one target site". Highly-effective modification mode in genome editing have been developed including simultaneous modification of multiplex genes, highly-effective insertion, replacement, and deletion of target genes in the genome scale, cut-paste of a large DNA fragment. These new tools for microbial genome editing will certainly be applied widely, and increase the efficiency of industrial strain improvement, and promote the revolution of traditional fermentation industry and rapid development of novel industrial biotechnology like production of biofuel and biomaterial. The technological principle of these genome-editing methods and their applications were summarized in this review, which can benefit engineering and construction of industrial microorganism.

Objective To research the expression and clinical significance of miR‐145 in the marrow of acute myeloid leuke‐mia (AML) .Methods A total of 70 cases of bone marrow samples were collected from AML patients ,of which included 46 cases of new diagnosed patients(initial treatment group) ,24 cases of AML patients in complete remission(remission group) .Fourteen ca‐ses of non‐neoplastic patients were used as controls(control group) .The miR‐145 relative expression level was detected by real‐time quantitative PCR .Results The relative expression level of miR‐145 in initial treatment group was less than those of control group and remission group(P<0 .01) .Compared to before‐chemotherapy patients ,the expression level of miR‐145 in the 9 case of AML patients with complete remission after chemotherapy increased significantly(P<0 .05) .The relative expression of miR‐145 showed no significantly correlation with the percentage of blasts cells in bone marrow and the percentage of peripheral blood leukocyte count (P=0 .456 ,0 .394) .Conclusion The expression of miR‐145 in bone marrow cells of AML patients is down‐regulated ,which sug‐gested the development of acute leukemia .

Objective To investigate the epidemic situation of trematode Aspidogastrea in the Huaihe River. Methods The mussels in the Huaihe River were collected numbered and dissected to detect the trematode and the species of trematodes were identified after dyeing. Results Totally 79 mussels were collected and the trematode Aspidogastrea were found from 23 mussels with the infection rate of 29.11% 209 trematode Aspidogastrea were collected and the average infectiosity of mussels was 9.09. Conclusion Trematode Aspidogastrea is endemic in the Huaihe River and the species is Aspidogaster sp.

It is the direct and main cause of trigeminal neuralgia that responsible vessel compresses the root entry zone of sensory root of trigeminal nerve.Microvascular decompression is an effective way in treating trigeminal neuralgia with higher cure and lower recurrence,which can eradicate the common cause of trigeminal neuralgia and maintain the normal function of trigeminal nerve;At the same time it is an safe way with lower risk on the basis of skilled microsurgical technique.So it is an optimal approach to treat trigeminal neuralgia.
