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 evaluate the diagnostic value of contrast-enhanced digital subtraction MRI in vertebra]metastatic tumors.Methods Forty-four vertebral metastatic tumors in thirty patients were scanned by routine MRI including SE T_1WI,SE T_2WI,STIR and enhanced T_1WI with an injection of Gd-DTPA(0.1 mmol/kg).Digital subtraction was performed between pre-contrast and enhanced T_1 weighted images.All the images of vertebral malignant tumors were evaluated by means of signal intensity ratio(SIR) and nose ratio(NR).The quality of images was also evaluated by comparing subtraction MRI with routine MRI.Results SIR and NR of subtraction MRI was 2.93,0.98 respectively.SIR of routine MRI (enhanced T_1WI,SE T_1 WI,SE T_2WI,STIR)was as follows:1.15,1.16,1.26,1.69.While NR of those was 5.25,3.44,4.56,23.32 respectively.SIR and NR of subtraction MRI images had significant statistical differences from those of routine MRI images(P

Objective To investigate the effects ofWenyujinessential oil on tau protein phosphorylation in mice with Alzheimer Disease (AD); To discuss the relevant mechanism of action.MethodsSixty Kunming mice were divided into six groups randomly: sham-operation group, model group,Wenyujin essential oil low- and high-dose group, donepezil group andShenzhiling group.β-Amyloid protein (Aβ25-35) was infused into the hippocampal of mice. Mice in each group were given relevant medicine for gavage for 15 d. After the last administration, immunohistochemistry was used to detect the expressions of tau protein phosphorylation points (Ser 404 and Thr 231). Western blot was used to detect tau protein phosphorylation points and the expression of PI3K/Akt protein. Results Compared with sham-operation group, tau protein phosphorylation points in the model group increased (P<0.05), but the phosphorylation levels of PI3K and Akt decreased significantly (P<0.05). Compared with the model group, tau protein phosphorylation (Thr231 and Ser404) inWenyujin essential oil high-dose group decreased significantly (P<0.05), and the phosphorylation levels of PI3K and Akt increased(P<0.01). ConclusionWenyujinessential oil can inhibit tau protein phosphorylation in mice. The possible mechanism may be related to the PI3K/Akt signal pathway.

Objective To investigate the curative effect of YU Yun pulse-feeling-based acupuncture therapy for the treatment of middle-late liver cancer. Methods A total of 60 middle-late liver cancer patients were divided into control group and treatment group by stratified randomization method,30 cases in each group. The control group was given integrated Chinese and western medicine therapy according to the clinical pathway, including anti-cancer treatment such as vascular interrention,molecular targeted therapy,chemotherapy,radio therapy, and focal ablation therapy,as well as chinese medicine treatment based on disease differentiation and syndrome differentiation. And the treatment group was given YU Yun pulse-feeling-based acupuncture therapy on the basis of treatment for the control group. The two groups received 12-week treatment, and then their curative effects were compared. Results The treatment group had better effect on increasing the survival rate, prolonging survival time, improving the scores of clinical symptoms, stabilizing tumor size, and increasing the scores of Karnofsky Performance Status (KPS)than the control group,the difference being significant (P < 0.05 or P <0.01). Conclusion YU Yun pulse-feeling-based acupuncture therapy exerts certain curative effect for the treatment of middle-late liver cancer.

Objective: To assess fluid-attenuated inversion recovery (FLAIR) vascular hyper-intensity (FVH) and explore its relationship with CT perfusion (CTP) penumbral/infarct core mismatch ratio and diffusion weighted imaging (DWI) final infarct volume in acute ischemic stroke (AIS) patients with middle cerebral artery occlusion (MCAO). Methods: The CTP and MRI images of 38 AIS patients with MCAO were reviewed. The FVH score (longitudinal direction) [FVH score (L)] and FVH score (transverse direction) [FVH score (T)] were quantified on the FLAIR images. The FVH score (L) (range, 0-16) was based on a rostrocaudal extension of FVH and the FVH score (T) (range, 0-3) was based on FVH supply of the occluded MCA territory. The mismatch ratio was calculated from the ratio of the [mean transit time - cerebral blood volume (CBV)] lesion/CBV lesion on the CTP images. The DWI infarct volume was measured on the DWI images. Results: The mismatch ratio was larger for the group of FVH score (L)=7~8 than those of FVH score (L)=5~6 and FVH score (L)=3~4 (p=0.03), whereas the DWI infarct volume was smaller (p=0.04). Similarly, the mismatch ratio of FVH score (T)=2~3 group was larger than FVH score (T)=1 group (p=0.01), whereas the DWI infarct volume was smaller (p=0.02). Both FVH score (L) and FVH score (T) correlated positively with mismatch ratio (P=0.02, P=0.001, respectively), but negatively with DWI infarct volume (P=0.03, P=0.004, respectively). Conclusions: Higher FVH score is associated with larger mismatch ratio and smaller DWI infarct volume in AIS patients with MCAO. FLAIR vascular hyperintensity may represent collateral arterial circulation, and may play a role in protecting the ischemic penumbra.

Objective To explore the dosage and injection method of concanavalin A(Con A) for inducing Wistar rats into the acute hepatic injury model. Methods (1)According to the dosage of Con A, 42 Wistar rats were randomly divided into groups A, B, C, D, E, N, 7 rats in each group. Group N was given tail intravenous injection of normal saline as normal control group. Groups A, B, C, D, E were given intravenous injection of 4, 8, 16, 30, 40 mg/kg of Con A respectively. At the 8th hour after modeling, the levels of alanine transaminase(ALT), aspartate aminotransferase(AST), albumin(ALB), interleukin(IL)-2 , IL-10, interferon (IFN)-γ, and tumor necrosis factor(TNF)-αwere detected. And HE staining was used to observe the pathological feature of hepatic tissue. (2)According to the injection method of Con A, 21 Wistar rats were randomly divided into normal control group, intraperitoneal injection group and tail intravenous injection group, 7 rats in each group. The dosage of Con A for the rats in intraperitoneal injection group and tail intravenous injection group was 16 mg/kg. At the 8th hour after modeling, the levels of serum ALT, AST, and ALB were determined. Results The number of abnormal deaths in various dose Con A groups at the end of each experiment was 0 in groups A, B, C, and 2 in group D, and 7 in group E. A small amount of spotty necrosis, inflammatory cell infiltration, and hepatic lobule with almost integrity of structure were found in groups A, B, while obvious bridging-like necrosis was seen in groups C, D. Serum ALT, AST, and ALB levels in intraperitoneal injection group had no statistically significant difference as compared with the normal control group. Conclusion Tail intravenous injection of 16 mg/kg of Con A can be used to induce an acute immunological liver injury rat model successfully.
