Edema, as one of common clinical diseases, could be treated by taking medicines and adopting external therapies with traditional Chinese medicines (TCM). In recent years, there have been many clinical and basic studies concerning external therapies with TCM on edema Data showed that the external therapies are mostly composed of such purgating drugs as Rhei Radix et Rhizoma, Natrii Sulfas and Pharbitidis Semen, heat-clearing drug such as Phellodendri Chinensis Cortex and resuscitation-inducing drug such as Borneolum Syntheticum. The study showed that ingredients of external therapies did not pass through hilum and hepatic system, and thus avoided the first pass effect of livers. They enabled effective components of drugs to be rapidly absorbed through pores and skins, strengthened the effect against edema, shortened the treatment course, decreased side effects, and were convenient and inexpensive. External therapies with TCM could play unique advantages in inhibiting edema in the future clinical studies.

Objective To study the relevance between blood loss, widespread brain contusion injury and consumptive coagulopathy. Methods One hundred and fifty-three cases with severe brain injury was studied about their coagulation data. Analyzed the relationship between blood loss group according to ≥3000 ml and < 3000 ml and coagulation features, the relationship between widespread brain contusion injury and disorder of coagulation;according to whether with brain contusion injury,kinds of bloods transplant and prognosis were asseseed;according to whether with widespread brain contusion injury in ≥ 3000 ml blood loss group,kinds of bloods transplant and prognosis were assessed. Results Compared with < 3000 ml blood loss patients, ≥ 3000 ml patients' blood coagulation changed obviously, with PT prolonging, Fbg and Plt decreasing, the differences were statistically significant (P < 0.05). Compared with no extensive brain contusion injury patients, in extensive brain contusion injury patients, APTT, PT, TT prolonged, Fbg and Plt decreased,and the difference was statistically significant (P <0.05). Extensive brain contusion injury patients with blood loss compared with those without such loss, needed more blood transfusion volume,larger amount of input of fresh frozen plasma Plt volume,the former survival rate was lower [68.29%(28/41)vs. 96.43%(108/112)], the difference between them was statistically significant (P< 0.05 ). In 41 patients who had brain widespread contusion ,the cases with extensive blood loss ( ≥ 3000 ml) were compared with those < 3000 ml, and the differences in blood transfusion treatment, fresh frozen plasma, Plt volume,survival rate were statistically significant (P < 0.05). Conclusion When blood loss ≥ 3000 ml after trauma,patients show various degrees of coagulopathy,and when accompanied with extensive brain tissue injury,coagulation disorders are more obvious, and the prognosis is even worse.

Lenalidomide is an oral immunomodulator with multiple functions including immune regulation, anti-tumor, and regulation of tumor microenvironment. Since the United States Food and Drug Administration (FDA) approved lenalidomide for the treatment of mantle cell lymphoma, recent studies have indicated that lenalidomide monotherapy or lenalidomide combinations in other types of lymphoma also has broad prospects. The treatment progress of lenalidomide in lymphoma will be summarized in this paper based on the new reports in the 57th American Society of Hematology (ASH) annual meeting.

OBJECTIVETo compare clinical effects between percutaneous compressing plating (PCCP) and proximal femoral nail antirotation (PFNA) for the treatment of patients with intertrochanteric fracture with risk external wall.
METHODSFrom September 2007 to June 2010, 43 patients with intertrochanteric fracture with risk external wall were treated by PCCP or PFNA according to different kinds of internal fixations. There were 22 cases in PCCP, including 9 males and 13 females with an average age of 68.4 (ranged, 60 to 86) years old, and 13 cases with type A2.2 and 9 cases with type A2.3; while 21 cases in PFNA, including 7 males and 14 females with an average age of 67.7 (ranged, 57 to 93) years old, and 10 cases with type A2.2 and 11 cases with type A2.3. Blood loss, operation time, hospital stay, fracture healing time, complications and Harris score after 1 years' following-up were observed and compared.
RESULTSAll patients were followed up for 12 to 22 (means 18.4) months, and all patients were obtained fracture healing, and recovered walking ability as before injury. There were no significant differences in blood loss, operation time, hospital stay, fracture healing time, complications and Harris score after 1 years' following-up (P>0.05). One case occurred displacement on the top of greater trochanter, and 1 case injuried weakness of hip abduction. One case occurred screw breakage in PCCP, while 1 case occurred hip joint pain in PFNA.
CONCLUSIONBoth of PCCP and PFNA in treating patients with intertrochanteric fracture with risk external wall can receive good clinical effects, while the effects and therapy strategy for displacement of bone on the top of lateral wall should further study.
