ObjectiveTo investigate the effect of medical elastic bandage and passive lower limb movement on blood pressure changes for patients with lithotomy surgery. Methods300 cases of lithotomy surgery patients in our hospital were randomly divided into three groups with 100 cases in each group.Group A was taken with routine care as the control group.Group B was taken with the medical elastic bandage based upon routine care.Group C was given passive movement in the lower limb based upon routine care.The blood pressure changes for three groups of patients were compared. ResultsThe lower extremities flat blood pressure was significantly reduced for patients of group A.The average arterial blood pressure decreased significantly at the flat lower limb immediately and after 5 min.The changes were statistically significant compared with patients of group B and C. ConclusionsThe medical elastic bandages and lower limb passive motion play a role in stabilizing the blood pressure of patients with lithotomy position surgery,which is worthy of clinical promotion.

Medical nutrition therapy (MNT)is the basic and long-term treatment of diabetes patients. At present,the dietary structure of type 2 diabetes mellitus(T2DM)patients in China has yet to be further improved. This article focused on the effect,dietary structure,food selection and guarantee of compliance of MNT in T2DM.We recommended that the dietary pattern should be designed based on the traditional dietary habits around the country,combined with people living and working reality. The rational utilization of network platform can improve the efficiency and compliance of nutrition education.

Different cells could be utilized as seed cells in the construction of tissue-engineered skelet al muscle, which include satellite stem cells, myohlasts, embryonic stem cells and mesenchymal stem cells includ-ing bone marrow-derived stem cells, amniotic fluid-derived stem cells, and adipose tissue-derived stem cells. Seed cells from different origins are capable of trans-differentiating into myogenic cells or fusing with myogenic cells, expressing the surface antigen of sarcogenic cells, and participating in the regeneration of muscle fiber, both in vivo and ex vivo. This review gives a summarization of the recent progress in the research on seed cell source in skelet al muscle tissue engineering.

[Objective] To observe the therapeutic effect of electroacupuncture(EA) collagen-induced arthritis(CIA) in rats and explore the partial mechanism via regulating blood rheology.[Methods] Bovine type II collagen was intradermally injected into the back of anesthetized rats to induce arthritis,the animal model of rheumatoid arthritis.Electroacupuncture(continuous waves,2 Hz,5 mA) was applied unilaterally and alternatively to Zusanli(ST 36) and Sanyinjiao(SP 6) for 30min,given once a day for 30 days.The paw edema,pain threshold and joint pathological changes in CIA rats were observed.Some indexes in blood rheology such as viscosity and erythrocyte aggregation were also examined.[Results] EA at point Zuansanli(ST 36) and Sanyinjiao(SP 6) reduced paw swelling and increased pain threshold significantly.Pathological damages of joint in CIA rats were effectively prevented by EA treatment.Meanwhile,the low blood viscosity in EA group were lower obviously than that in control group,and the erythrocyte aggregation indexes were down-regulated by EA.[Conclusion] EA has a pronounced therapeutic effect on collagen-induced arthritis in rats.Regulating the blood rheology in CIA rats may be the mechanism of EA.

As a new biotechnology, protein transduction connects the target fragment with biology active and protein transduction domain, and transducer it in to cells, exert its biological effects. Protein transduc-tion domain is a small molecule peptide, not only the protein transduction domain can penetrate through cell membrane, but could maintain the activity of its fusion protein. Protein transduction is an emerging biology technology, it has been applied into all aspects of cell gene regulation since its invention. In this article, we take Tat, Pdx-1 and Beta/NeuroD for instance and review the application of transduction protein in the dif-ferentiation of pancreatic stem cell.

Diabetic gastroparesis (DGP) is a common complication in patients with diabetes mellitus of long duration, presenting with recurrent nausea, vomiting, postprandial fullness and early satiety caused by delayed gastric emptying. The treatments of DGP include dietary therapy, nutritional support, glycemic control, use of prokinetic and antiemetic agents. This review focuses on current status of the drug treatment and the progress of new agents of DGF under the preclinical and clinical trials.

Epstein-Barr(EB)virus is the first carcinogenic virus discovered in 1964.EBV infection is common in pediatrics and most of the infected children are asymptomatic.When the immune function of children becomes low or deficient, EBV may cause a series of benign or malignant lymphoproliferative diseases, such as infectious mononucleosis, chronic active EBV infection, hemophagocytic lymphohistiocytosis, post-transplant lymphoproliferative disorders, X-linked lymphoproliferative syndrome and so on.Most of these diseases have complex pathogenesis, diverse clinical manifestations, poor prognosis and high mortality.The only effective treatment is allogeneic hematopoietic stem cell transplantation.

Melatonin has a significant inhibitory effect on various cancers,especially on breast cancer.In estrogen receptor (ER)-positive human breast cancer,anti-cancer effects ofmelatonin on breast cancer cells and transplanted tumors mainly achieve by suppressing ER mRNA expression and ER transcriptional activity via the MT1 receptor.In addition,melatonin regulates the transactivation of other members of the nuclear receptor super-family,estrogen metabolizing enzymes,and the expression of related genes.Furthermore,melatonin also suppresses tumor aerobic metabolism,critical cell-signaling pathways relevant to cell proliferation,survival,metastasis,and drug resistance.Melatonin demonstrates both cytostatic and cytotoxic activity in breast cancer cells that appears to be cell-type specific.Studies on animal and human models indicate that disruption of the circadian nocturnal melatonin signal promotes the growth,metabolism,and signaling of human breast cancer,resulting in invalid hormone therapy and chemotherapeutic resistance in breast tumors.

Objective :To explore the significance of mitochondrial DNA mutations of articular chondrocytes in the rat model of temporomandibular joint osteoarthrosis (TMJOA). Methods:TMJOA models were created in left sides of TMJ of 15 SD rats by the partial resection of the articular disc.The experimental rats were killed 3 months after operation. After the chondrocytes culture, the entire mtDNA were amplified using 32 pairs of overlapping. DNA fragments showing different banding patterns between normal and experimental mtDNA by temporal temperature gradient gel electrophoresis were sequenced to identify the mutations. Results: Of the 35 heteroplasmic pattern PCR products, 42 novel mutations were found, Majority of the novel mutations were in the tRNA and D-loop regions. Conclusion:The mutations occurred in the mtDNA of TMJOA articular chondrocytes.

Objective To explore the anxiety and depression in caregivers of patients in persist vegetative state and minimally conscious state, and discuss the related factors. Methods From January, 2010 to December, 2014, 60 caregivers of 60 patients in persist vegetative state and minimally conscious state were assessed with Self-rating Anxiety Scale (SAS) and Self-rating Depression Scale (SDS). The sex, ed-ucation level, relation to the patients and family income of the caregivers, and the age of the patients and number of the families of the pa-tients were recorded, and analyzed with Logistic regression. Results 55％caregivers were found in anxiety, and 48.4％in depression. The fe-male caregivers (OR>6.870, P<0.05), the number of the family of the patients (OR<0.233, P<0.05) and age of the patients (OR<0.294, P<0.05) were independent factors associated with anxiety and depression. Conclusion The caregivers of patients in persist vegetative state and minimally conscious state are troubled in anxiety and depression, especially the female, while age and the number of the families of patient may be important factors for it.
