2.Thinking on building the network cardiovasology of Chinese medicine.
Journal of Integrative Medicine 2012;10(11):1206-10
With advances in complex network theory, the thinking and methods regarding complex systems have changed revolutionarily. Network biology and network pharmacology were built by applying network-based approaches in biomedical research. The cardiovascular system may be regarded as a complex network, and cardiovascular diseases may be taken as the damage of structure and function of the cardiovascular network. Although Chinese medicine (CM) is effective in treating cardiovascular diseases, its mechanisms are still unclear. With the guidance of complex network theory, network biology and network pharmacology, network-based approaches could be used in the study of CM in preventing and treating cardiovascular diseases. A new discipline-network cardiovasology of CM was, therefore, developed. In this paper, complex network theory, network biology and network pharmacology were introduced and the connotation of "disease-syndrome-formula-herb" was illustrated from the network angle. Network biology could be used to analyze cardiovascular diseases and syndromes and network pharmacology could be used to analyze CM formulas and herbs. The "network-network"-based approaches could provide a new view for elucidating the mechanisms of CM treatment.

Objective To investigate the effect of sufentanil on anoxia/rexogenation (A/R)-induced injury to H9c2 cells incubated in high-glucose culture medium. Methods The H9c2 cells were cultured in low-glucose DMEM/F12 culture medium supplemented with 10% fetal bovine serum. The cells were seeded in 96-well or 6-well plates and randomly divided into 5 groups ( n = 12 wells each): normal glucose control group (group NC),high-glucose control group (group HC), high-glucose + A/R group (group HA/R), high-glucose + sufentanil +A/R group (group HSA/R), high glucose + naloxone + A/R group (group HNA/R). The cells were exposed to 95 % N2-5 % CO2 in an incubator at 37 ℃ for 3 h followed by 3 h reoxygenation. In group NC, the cells were incubated in low-glucose culture medium for 48 h. In group HC, the cells were incubated in high-glucose culture medium for 48 h. In group HA/R, the cells were incubated in high-glucose culture medium for 48 h before anoxia.In group HSA/R, after the cells were incubated in high-glucose culture medium for48 h, sufentanil was added to the culture medium with the final concentration of 10-9 mol/L at 15 min before anoxia. In group HNA/R, after the cells were incubated inhigh-glucose culture medium for 48 h, naloxone was added to the culture medium with the final concentration of 10-6 mol/L, 10 min later sufentanil was added with the final concentration of 10-9 mol/L at 15 min before anoxia. The cell viability was measured by MTT assay. The amount of lactic dehydrogenase (LDH) released in the supernatant and superoxide dismutase (SOD) activity were measured. Results The cell viability and SOD activity were significantly lower, while the amount of LDH released was significantly higher in the other groups than in group NC, in groups HA/R and HNA/R than in group HC, and in group HNA/R than in group HSA/R (P < 0.01 ). The cell viability and SOD activity were significantly higher, while the amount of LDH released was significantly lower in group HSA/R than in group HA/R ( P < 0.01 ). There was no significant difference in the parameters mentioned above between group HNA/R and group HA/R ( P > 0.05). Conclusion Sufentanil can attenuate A/R-induced injury to H9c2 cells with high-glucose incubation, and the mechanism may be related to the activation of opioid receptors.

Objective To investigate the effects of radix salvia miltiorrhizae on the apoptosis of hepatoeytes during cold preservation and reperfusion injury in rat donor liver. Methods Forty male SD rats were divided into experimental group, control group and sham operation group. The rat model of liver transplantation was established according to the Kamada method. The grafts were preserved in lactated Ringer's solution with radix salvia miltiorrhizae in experimental group and in lactated Ringer's solution in control group for 5 hours, then they were transplanted orthotopically. Six hours after transplantation, the recipients were sacrificed, and the serum ALT and AST were detected by automatic biochemistry analyzer, the hepatocyte apoptosis by TUNEL, the expression of Bcl-2 and FasL protein by flow cytometry. The histopathological changes of the liver grafts were observed under light microscope. Results The levels of ALT and AST in the experimental group were significantly lower than those in the control group after reperfusion. Compared with that in the control group, the apoptosis index of the hepatoeyte was signifieandy decreased in the experimental group ( F = 133.802, P <0.05 ), while the level of Bel-2 protein expression was increased ( F = 91.063, P < 0.01 ). No statistical difference upon FasL protein expression was detected between the 2 groups( F = 1.329, P >0.05). The histopathological injury of the liver grafts in the experimental group was significantly slighter than that in the control group. Conclusions Radix salvia mihiorrhizae inhibits the apoptosis of hepatocytes by increasing the Bcl-2 protein expression during cold preservation and reperfusion injury, so it has a protective effect on the liver graft against ischemia reperfusion injury.

Objective To investigate the surgical treatment for ipsilateral fractures of femoral neck and shaft. Methods 26 cases of ipsilateral fractures of femoral neck and shaft treated from January 1996 to December 2002 were retrospectively reviewed. There were 22 males and 4 females, with an average of 28 years (range 17-50 years). The causes of fractures were traffic accident in 17 and fall in 9. The femoral neck fractures were diagnosed in emergency in 16 cases, and delayedly in 10 cases. The delayed time was 3-75 days, with an average of 13.1 days. All cases were divided into three types according to the site of femeral shaft fracture. Type Ⅰ: the proximal 1/3 femoral shaft fracture combined with neck fracture, in 3 cases; Type Ⅱ: the middle 1/3 femoral shaft combined with neck fracture, in 18 cases; Type Ⅲ: the distal 1/3 femoral shaft fracture combined with neck fracture in 5 cases. All cases were undergone surgical reduction and internal fixation. The femoral shaft fractures were stabilized with dynamic compression plate (DCP) in 13, with antegrade intramedullary locking nail in 2 cases, with retrograde intramudullary locking nail in 5 cases. The femoral neck fractures of these 20 patients were stabilized with cannulated lag screw. The femoral neck and shaft were stabilized with dynamic hip screw system (DHS) in 2, with constructive nail in 4. Results All of the patients were followed up for 3 to 9 years, with an average of 4.4 years. The femoral shaft fractures obtained rigid union at the latest follow-up study in 25. The duration for bone union ranged from 16 to 32 weeks, with an average of 20 weeks. The femoral neck fractures were united at the latest follow-up study in 25. The duration for bone union ranged from 12 to 28 weeks, with an average of 16 weeks. The complications included infection in 1, hardware failure in 1, nonunion of femoral neck fracture in 1 and osteonecrosis of femoral head in 1. Conclusion The ipsilateral fracture of femoral neck and shaft is rare, and the neck fracture is easy to miss diagnosis. The surgical treatment for ipsilateral fractures of femoral neck and shaft depends on the position of femoral shaft, and the situation of femoral neck.
