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.

For the determination of the usefulness of the pulsed Doppler echocardiographic diagnosis of ASD. We evaluated 185 children with congenital heart disase by subxiphoid approach. ASD was diagnosed when abnormal flow was recorded in right atrium. ASD was proved by surgery in 33 of 185 children with congenital heart disease, and all children had sugical correction of their heart deformities. On pulsed Doppler echocardiographic exmination, abnormal flow was recorded in 32 of the 33 children with ASD and 3 of 152 children without ASD. This pulsed Doppler echocardiographic diagnosis of ASD by abnormal flow in right atrium has sensitively of 97% and specificity of 98%. High correlation was found between the estimates of Qp/Qs ratio by Doppler and Fick method(r=0.90, P<0.01). So we concluded that pulsed Doppler echocardiographic diagnosis of ASD was specific and sensitive method and careful pulsed Doppler echocardiographic examination may avoid the unnecessary cardiac catheterizetion in patients with ASD.

Objective To evaluate the effects of curcumin on the activity of NR2B and NR1 in the spinal dorsal horn in a rat model of diabetic neuropathic pain (DNP).Methods Diabetes mellitus was induced by high-sucrose and high-fat diet and intraperitoneal streptozotocin 35 mg/kg,then confirmed by fasting blood glucose level ≥ 16.7 mmol/L 3 days later in male Sprague-Dawley rats.DNP was confirmed by the mechanical paw withdrawal threshold (MWT) and thermal paw withdrawal latency (TWL) measured on day 14 after streptozotocin administration < 80% of the baseline value.The rats were then randomly divided into 3 groups (n =27 each) using a random number table:DNP,DNP+ curcumin group (group DCur)and DNP + solvent control group (group DSC).Curcumin 100 mg· kg-1 · d-1 and corn oil 4 ml· kg-1 · d-1 were injected intraperitoneally for 14 consecutive days starting from 14 days after administration of streptozotocin in DCur and DSC groups,respectively.Another 27 normal male Sprague-Dawley rats served as control group (group C) and were fed with normal forage.At 3,7 and 14 days after curcumin injection,MWT and TWL were measured and the lumbar segments (L4-6) of the spinal cord were removed.The expression of pTyr1472-NR2B and pSer896-NR1 in the spinal dorsal horn was determined by immunohistochemistry and Western blot.Results Compared with group C,MWT was significantly decreased,TWL was shortened,and the expression of pTyr1472-NR2B was up-regulated at each time point in group DNP.Compared with group DNP,MWT was significantly increased,and TWL was prolonged at 7 days after curcumin injection,and the expression of pTyr1472-NR2B was down-regulated at 3 days after curcumin injection in group DCur.There was no significant difference in each parameter between DNP and DSC groups,and in the expression of pSer896-NR1 between the four groups.Conclusion The mechanism by which curcumin mitigates neuropathic pain in type 2 diabetic rats may be related to inhibition of up-regulation of pTyr1472-NR2B expression,while unrelated to pSer896-NR1 expression in the spinal dorsal horn.
