The review explains the function and mechanism of the promoting blood circulation for removing blood stasis herbs in treating hepatic fibrosis from the aspects of the monomer, effective constituent and compound recipe. It provides basis for application of promoting blood circulation for removing blood stasis herbs in study and treating hepatic fibrosis.

Objective To observe and analyze the reasons of intra-abdominal hypertension,and to discuss the influence of intra-abdominal hypertension (IAH) on recipients' respiratory function and its changes after disposition.Method During January to June in 2012,50 patients who had performed orthotopic liver transplantation were involved in this study.Intra-abdominal pressure was measured by AbViser Intra-Abdominal Pressure Monitoring Kit.According to the value of intra-abdominal pressure,the patients were divided into two groups (IAH group and control group).The reasons of IAH were observed and analyzed.Respiratory rate,oxygenation index,and the arterial partial pressure of carbon dioxide between IAH and control groups were compared.IAH was dealt with restricting oral input,inserting nasogastric tube,administering enema,inserting ilues tube or placing percutaneous catheter drainage according to reasons.Intra-abdominal pressure,respiratory rate,oxygenation index,and arterial partial pressure of carbon dioxide were also observed after disposition.Result The incidence of IAH was 44％ (22/50).The respiratory rate of patients in IAH group was quicker than that in control group.The oxygenation index in IAH group was lower than that in control group.The arterial partial pressure of carbon dioxide in IAH grade I group was not higher than in control group.However,the arterial partial pressure of carbon dioxide in IAH grade Ⅱ and Ⅲ groups was higher than in control group.After disposition,the intra-abdominal pressure,respiratory rate and arterial partial pressure of carbon dioxide in IAH groups were decreased from 16.4 ± 3.1 mmHg,33.0 ± 5.2 L/min and 47.6 ± 9.4 mmHg to 10.5 ± 1.8 mrnHg,19.7 ± 4.1 L/min and 39.9 ± 2.9 mmHg respectively,while the oxygenation index was increased from 202.7 ± 72.9 mmHg to 350.5 ± 98.5 mmHg.Conclusion The incidence of IAH after orthotopic liver transplantation was high.The influence of IAH on patients' respiratory function was serious.After timely and proper disposition,the respiratory function of patients with IAH could be improved.

BACKGROUND:The vascularization plays a key role in bone formation and reconstruction. Bioactiveβ-tricalcium phosphate has a porosity and absorbability that al ow a possibility of constructing vascularized bone.
OBJECTIVE:To explore the blood supply and construction of the central vascularizedβ-tricalcium phosphate, as wel as the mechanism of vascularization in artificial bone for its further clinical application.
METHODS:The lumbar dorsal artery of New Zealand rabbits was isolated and prepared into vascular bundle. At the experimental side, the vascular bundle was implanted into channel of theβ-tricalcium phosphate, then fil ed with the autologous tiny bone particles, and embedded into the latissimus dorsi muscle. Animals without the vascular bundle implantation were taken as the control group. The samples were determined for the morphology and histology at 4, 8, and 12 weeks post-surgery.
RESULTS AND CONCLUSION:The site where the vascular bundle was implanted appeared foramen nutriens-like structure, the blood vessels were abundant and smooth. The central vascularized tricalcium phosphate were fil ed with new-born vessels at 4-8 weeks. The newly formed bone and bone metabolism appeared at 4 weeks and newly formed bones were more mature at 12 weeks. In the control group, there were only a few new-born vessels, the newly formed bone was immature. The central vascularizedβ-tricalcium phosphate can significantly improve the vascularization of artificial bone. This model can probably serve as a new method for tricalcium phosphate in clinical use.

AIM: To observe the clinical effect of the tonifying kidney pills with mingmuwuzi treating evaporative dry eyes.METHODS: This study adopted the positive drug control,prospective study,random number remainder grouping method to 65 cases of outpatient patients diagnosed with evaporative dry eyes which were divided into the treatment group 32 cases (64 eyes) and the control group 33 cases (66 eyes).The treatment group took the decoction of kidney pills with mingmuwuzi,combined with sodium hyaluronate eye drops.The control group simply use sodium hyaluronate eye drops,both group were set to 4wk for a course of treatment.To observe the symptoms and signs of two groups before and after the treatment,the change of the evaluation index and curative effect were evaluated.RESULTS: The effectiveness of the treatment group was 87.5%,the control group was 78.8%,the difference was statistically significant (z=-3.149,P<0.05).CONCLUSION: The treatment of the kidney pills with mingmuwuzi combined with sodium hyaluronate eye drops to evaporative dry eyes is more effective than the simple use of sodium hyaluronate eye drops.

Many Novel approaches of epigenetic reprogramming of somatic cells have been reported. However,ethical issues caused by somatic nuclear transfer have triggered the development of alternative strategies for reprogramming somatic cells. Recently,many new advances have been acquired for reprogramming somatic cells,which could reverse differentiated somatic cells to a totipotent embryonic state,such as fusion of potential stem cells with somatic cells,incubation of cells in potential cell-free extraction and introduction of defined pluripotency factors into somatic cells. The epigenetic modification in these reprogramming processes,including germ cells and early embryoes,somatic nuclear transfer and other approaches for reprogramming of somatic cells were reviewed. Studies of epigenetics will be benefit for understanding the precise mechanism and improving the efficiency of somatic nuclear reprogramming,which will be eventually applied in the basic study and practice.
