This article introduced the experience of Professor YU Yun in treating the primary carcinoma of liver by using acupuncture after pulse diagnosis. Professor YU thinks that the overall pathogenesis of liver cancer is deficiency of zang-fu organs, so the cancer cells can invade and occupy in the liver. Therefore, Professor YU uses the way of supporting the healthy qi and driving out the cancer as the treatment principle from multiple organs and meridians. On the basis of the theories of Nei Jing, Professor YU creates the acupuncture after pulse diagnosis. He feels the pulse on the basis of four pulses: Cunkou, Renying, Chongyang, and Taixi. According to the feelings of the pulses, he compares the size and speed, strong or weak, smooth or nonfluency of the four pulses. In treatment, he uses reducing method when the pulse is strong and fast, and tonic method when the pulse is weak and slow. He chooses the main acupuncture points on head, face, belly, flank and lower limbs. According to the experience, Professor YU uses gold needle in tonic method and uses silver needle in reducing method. In this way, the acupuncture after pulse diagnosis can regulate zang-fu organs and meridians, yin and yang, qi and blood, and promote blood circulation for removing blood stasis and resolving dampness, and attack the retained fluid and tumour in the liver, and combined with adjunct points to treat cancer.

Objective To assess the effect of anemia on long-term outcomes in patients with acute coronary syndrome(ACS) undergoing pereutaneous coronary intervention(PCI). Methods In 3136 patients presenting with ACS,636 patients were anemic. The clinical features, mortality and major cardiocerebral events including non-fatal acute myocardial infaret,revascularization and non-fatal cerebral stroke were compared in patients with or without anemia. The average follow-up period was 550 days. Results Anemic patients were older and had a higher percentage of comorbidities compared with nonanemic cohorts. Compared with nonanemic patients, anemic patients had higher mortality (4.7% versus 1.5% ,P <0. 001) and a higher major adverse end point events,including nonfatalmyocardial infarction, stroke and revaseularization (14.2% versus 11.0%, P = 0.032). After adjustment for comorbidities, anemia was associated with a higher risk of mortality after percutaneous coronary intervention (adjusted hazard rate ratioRR2. 166 ;95% CI 1. 298-3. 612 ;P =0.003). Conclusion Anemia before PCI is an independent factor for predicting the long-term mortality of ACS.

OBJECTIVETo explore the changes in the mRNA expression of adiponectin (Adp), adiponectin receptors(AdpR), and leptin in different adipose tissues of Wannanhua pigs at different stages of development, and their sexual dimorphism.
METHODSFive Wannanhua boars and five Wannanhua gilts were sampled at birth, 30, 45, 90, and 180 days of age respectively. The delta delta Ct relative quantification real-time PCR was used to detect the transcription levels of Adp, AdpR1, AdpR2, and leptin mRNAs in subcutaneous (SC) and perirenal (PR) adipose tissues, and beta-actin were used as internal standards.
RESULTSThe expression level of Adp, AdpR1, AdpR2, and leptin mRNA in SC and PR adipose tissue were changed with age significantly (P < 0.01). In general, Adp mRNA expression in SC adipose tissue was significantly lower than that in PR adipose tissue (P < 0.05), while AdpR1, AdpR2, and leptin mRNA expression in SC adipose tissue were significantly higher than those in PR adipose tissue (P < 0.05 or P < 0.01). Although the sexual dimorphism were found in apart genes or apart days of age, Adp, AdpR1, AdpR2, and leptin mRNA expression both in SC adipose tissue and PR adipose tissue had no significant differences between Wannanhua gilts and boars in general. Significant positive correlation was found between Adp and AdpR1, AdpR2 (P < 0.05 or P < 0.01), and significant negative correlation was found between Adp and leptin (P < 0.05) in SC adipose tissue and PR adipose tissue respectively (P < 0.05).
CONCLUSIONThe expression of Adp, AdpR1, AdpR2, and leptin mRNA in adipose tissue of Wannanhua pigs followed specific developmental patterns and tissue specificity. Adp correlated with its receptors.
