Influence of Acupuncture on Microcirculation Perfusion of Pericardium Meridian and Heart in Acute Myocardial Ischemia Model Rats / 中国结合医学杂志

OBJECTIVE@#To observe the influence of acupuncture on microcirculation perfusion of the pericardium meridian and heart in acute myocardial ischemia (AMI) rats and evaluate whether acupuncture can simultaneously affect the meridians and corresponding viscera. Additionally, acupoints at different meridians were compared and whether they exert the same effects was discussed.@*METHODS@#Totally 32 Sprague-Dawley rats were subjected to left anterior descending (LAD) ligation to develop an AMI model. Rats were divided into 4 groups, including AMI, acupuncture Neiguan (PC 6), Lieque (LU 7) and Qiansanli (LI 10) groups (n=8). Eight rats received only thoracotomy (sham-operated group). The rats in the acupuncture groups received manual acupuncture at PC 6, LU 7 and LI 10 acupoints for 15 min, respectively. The microcirculation perfusion of pericardium meridian and heart was monitored by laser speckle perfusion imager (LSPI) before, during and after acupuncture manipulation for 15 min. Subsequently, the perfusion unit (PU) was calculated and analyzed by PSI System.@*RESULTS@#After LAD, compared to pre-acupuncture stage, the heart microcirculation perfusion (HMP) in the AMI group decreased continuously at during-acupuncture (P>0.05) and post-acupuncture stages (P0.05). Compared to pre-acupuncture stage, the PMP and HMP in PC 6 group significantly increased during acupuncture manipulation (both P0.05); however, they were significantly reduced after acupuncture manipulation (both P<0.05). Additionally, HMP of LI 10 group was decreased significantly during acupuncture, especially compared to pre-acupuncture stage (P<0.05).@*CONCLUSIONS@#Acupuncture at PC 6 obviously increased the PMP and HMP in AMI rats, and the effects were superior to at LU 7 and LI 10 acupoints. It was further confirmed that acupuncture promoted qi and blood circulation, indicating that acupoint specificity exists and features a meridian-propagated effect.

A young boy with elevated aminotransferases in physical examination--Two novel missense mutations associated with Wilson's disease were found / 中国当代儿科杂志

A 3-year-old boy had abnormal liver function, which was found in physical examination, for 5 months before admission. He had no symptoms such as anorexia, poor appetite, and jaundice, had normal growth and development, and showed no hepatosplenomegaly. Laboratory examination revealed significantly reduced ceruloplasmin (35 mg/L), as well as negative hepatotropic virus, cytomegalovirus, and Epstein-Barr virus. There were normal muscle enzymes, blood glucose, and blood ammonia and negative liver-specific autoantibodies. The boy had negative K-F ring and normal 24-hour urine copper (0.56 μmol/L). The ATP7B gene testing for the boy, his sister, and their parents detected two novel missense mutations in the boy and his sister, i.e., compound heterozygous mutations in exon 7 (c.2075T>C, p.L692P) and exon 13 (c.3044T>C, p.L1015P), which were inherited from their father and mother, respectively. Wilson's disease was confirmed by genetic diagnosis in the boy and his sister. The boy and his sister were given a low-copper diet. The boy was administered with penicillamine for decoppering and zinc supplement against copper uptake. His sister received zinc supplement alone because no clinical symptoms were observed. The boy showed normal liver function in the reexamination after 3 months of treatment.

Effect of different sorts of fertilizer on content of Tanshinone Ⅱ_A of cultivated Radix Salvia Miltiorrhizae / 中成药

Objective: To study the effect of different sorts of fertilizer on the content of tanshinone Ⅱ A, the effective element of cultivated Radix Salvia miltiorrhizae. Methods: Fertilize Radix Salvia miltiorrhizae with the several kinds of combination: the oddment cake(round flat cake made of residue of seed after extracting oil form it), pig manure, chicken manure, duck manure, human excrement, plant ashes, dregs of a decoction (residue of Traditional Chinese medicine material after being extracted), phosphoric fertilizer and compound fertilizer; and gather Radix Salvia miltiorrhizae one year later. Determine the content of Tanshinone Ⅱ A in cultivated Radix Salvia miltiorrhizae by HPLC. Results: The contents of Tanshinone Ⅱ A in Radix Salvia miltiorrhizae fertilized by different sorts of fertilizer are of significant difference. Conclusion: Plant ashes, oddment cake and compound fertilizer are good for growing of Radix Salvia miltiorrhizae and raises of the content of Tanshinone Ⅱ A.
