Objective:To prove the feasibility and validity ofXing Nao Jing acupoint-injection (XNJ-AI) at Fengchi (GB 20) for pseudobulbar palsy caused by ischemic stroke (PBP-IS).
Methods:An assessor-blinded, two-parallel-group, randomized controlled trial was conducted, and the patients with PBP-IS were recruited and randomly divided into two groups. Patients in the control group received oral aspirin (100 mg per day for 2 weeks). In addition to oral aspirin; patients in the treatment group received XNJ-AI at Fengchi (GB 20), once a day, for two weeks. The primary outcome was assessed by the water-swallowing test (WST). Thromboxane B2 (TXB2) and 6-keto-prostaglandin F1a (6-keto-PGF1a) in plasma were measured before and after the treatment.
Results:In the treatment group, the percentage of swallowing function no less than grade 3 before and after the treatment was 32% and 88%, respectively; in the control group, it was 28% and 76% before and after the treatment, respectively; the difference after the treatment between the two groups was statistically significant (P<0.05). There were statistical differences between pre- and post-treatment levels of plasma TXB2and 6-keto-PGF1αin the two groups (bothP<0.05). After the treatment, there were significant differences in the levels of plasma TXB2 and 6-keto-PGF1α between the two groups (bothP<0.05).
Conclusion:XNJ-AI at Fengchi (GB 20) can improve the patients’ swallowing function and balance the levels of TXB2 and 6-keto-PGF1α in plasma.

Objective To explore the effect of motivational interviewing on the self-care of type 2 diabetic patients . Methods Totally 96 inpatients with type 2 diabetes were randomly divided into the control group and the intervention group , each group containing 48 patients. The control group received routine diabetes education, while the intervention group received face-to-face and one-by-one motivational interviewing intervention for three months. The patients′self-care level were evaluated by using diabetes self-care scale after intervention. Result After intervention, the score on the self-care behaviors including diet control, exercise therapy, medication , blood glucose monitoring and foot care were significantly higher in the intervention group than those in the control group (P < 0.01). Conclusion Motivational interviewing can improve the ability of type 2 diabetic patients to control the glycemic level.

OBJECTIVE: Inter-oocyte cytoplasmic transfer has been performed recently as a means to improve the outcome of assisted reproductive methods and becomes a hotspot. To overview the recent advances and problems in this area in this article, and put forth a new concept of reverse cloning technique based on ooplasmic transfer. DATA SOURCES: An online search of PUBMED was undertaken to identify correlative English articles published from January 1998 to December 2006 by using the keywords of "ooplasmic transfer, mitochondria heteroplasmy,animal cloning". Meanwhile, relevant Chinese articles published between January 1998 and December 2005 were searched in Wanfang database with the same keywords in Chinese. STUDY SELECTION:The articles were primarily screened, and the citations at the end of each reference were reviewed. Inclusion criteria: The articles related to the research of ooplasmic transfer, cloning or reverse cloning. Exclusion criteria: Repetitive studies or Meta analytical articles. DATA EXTRACTION:Totally 126 relevant articles were collected, and 31 of them were in accordance with the inclusion criteria, while 95 of them were excluded because of repetition or obsolescence. In 31 articles met the criteria, 17 studies were relevant to the ooplasmic transfer, 13 studies related to animal cloning and one study related to reverse cloning. DATA SYNTHESIS: Exciting advances have been achieved in human gamete biology, and ooplasmic transfer have been widely applied. Many studies indicated that mitochondria in oocytoplasm affected obviously the fertilization of the oocytes and early embryo development. Lots of experiments have been done on the interaction of cytoplasm and nucleus as well as the mechanism of genomic reprogramming to further the investigation. Meanwhile, the techniques are progressed. Cloning techniques is excellent in application prospect, while there are some problems at the same time. Therefore the concept of reverse cloning technique was proposed based on ooplasmic transfer. CONCLUSION: The mitochondria in oocytoplasm has remarkable effect on the fertilization of the oocytes and early embryonic development. However, ooplasm transfer can lead to mitochondria DNA heteroplasmy, and more work must be done on potential problems. The reverse cloning technique based on the ooplasmic transfer has a good prospect.
