OBJECTIVE: To investigate the effect of Shenfuqiangxin capsule and the underlying mechanism on cardio-renal syndrome(CRS) in rats induced by infrarenal aortic-clamping after renal ischaemia.METHODS: Male Wistar rats underwent infrarenal aortic-clamping after renal ischaemia or sham operation. The surviving CRS rats were divided randomly into three groups: CRS group(CRS + 10 m L·kg-1·d-1pure water by gavage), SFQX group(CRS + 13.2 g crude drug·kg- 1·d- 1Shenfuqiangxin by gavage),and handleregionpeptide(HRP)group(CRS+10mg/kg HRP by vein). Sham operation rats were given10 m L·kg-1·d-1pure water. Treatments were given8 weeks after surgery, which lasted for 4 weeks. Therats were detected for heart structure and function by transthoracic echocardiography. PPR m RNA was detected by Reverse Transcription Polymerase Chain Reaction(RT-PCR). To determine whether the mitogen-activated protein kinase(MAPK) signal pathway is included in the heart and kidney protective function of Shenfuqiangxin capsule, MAPK related proteins such as posophorylated C-Jun amino terminal kinase(p-JNK), posophorylated extracellular signal-regulated kinase ?(p-ERK1/2), posophorylated p38(p-p38) were examined by Western Blot.Apoptosis in heart and kidney tissues were detected by d UTP Nick End Labeling staining.RESULTS: Shenfuqiangxin capsule alleviated myocardial apoptosis and inhibited PRR m RNA expression and p-JNK, p-ERK1/2, p-p38 proteins expression in CRS rats.CONCLUSION: All the results suggest that Shenfuqiangxin capsule improves the injured heart and kidney function maybe through inhibition of MAPK response pathway.
OBJECTIVE:To study the effects of temperature on different facial areas by suspended moxibustion at two points,Zusanli(ST 36) and Hegu(LI 4),and probe the phenomena underlying self-regulation in the human body after thermal stimulation.METHODS:Thirty healthy volunteers accepted moxibustion over Zusanli(ST 36) and Hegu(LI 4),and the order of moxibustion points was randomly determined.Moxibustion method:suspension of moxibustion over Zusanli(ST 36) and Hegu(LI 4) on both sides was performed using an ignited moxa stick stuck in a support for 20 min.Observation method:An infrared thermal image of the face was taken before and after suspended moxibustion using a CK350 medical infrared thermal imaging instrument.Data analysis:A thermal microscopic section view system(TMTSys) was used to analyze the change in temperature in special facial areas.Statistical analysis was carried out using SPSS 14.0 software.RESULTS:Before moxibustion was suspended,the facial thermal image showed a T-shaped thermal area related to the vascular distribution with even temperature and good symmetry on both sides.Suspended moxibustion over Zusanli(ST 36) have a very significant increase in temperature at the forehead,around the nose,at the corners of the mouth,and at the cheeks and lips(P<0.01).Suspended moxibustion over Hegu(LI 4) also have a significant(P<0.05) increase in temperature around the nose,the corners of the mouth,the cheeks,and lips,where has a new high temperature area was formed(P<0.01).Suspended moxibustion over Hegu(LI 4) raised the temperature at the middle point of the lips more obviously than did Zusanli(ST 36) in the same person,(P<0.05).After 10 min of moxibustion over Zusanli(ST 36) and Hegu(LI 4),the change in temperature in the facial area reached its peak value.CONCLUSIONS:Facial infrared thermography of healthy people revealed a T-shaped thermal area reflecting a physiological thermal area.Moxibustion over Zusanli(ST 36) or Hegu(LI 4) raised the temperature in this facial T-shaped thermal area.Hegu(LI 4) led to the
