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.

ObjectiveTo study the expression changes of peripheral blood monocyte human leukocyte antigen DR (HLA-DR) in patients with severe craniocerebral injury,and investigate the correlation between HLA-DR expression and infection and prognosis.MethodsNinety patients with craniocerebral injury were selected as experimental group and were divided according to the Glasgow coma scale (GCS) score after hospitalization into experimental group 1 (GCS score 13-15 scores ),experimental group 2 (GCS score 9-12 scores) and experimental group 3 (GCS score 3-8 scores) with 30 patients each,which were moderate,medium,severe craniocerebral injury,respectively.Thirty healthy people were chosen at the same period as control group.The HLA-DR expression of experimental group was detected after 1,3,7 and 14 d of admission by flow cytometry,and the HLA-DR expression of control group was detected on the day they got physical examination.The rates of infection,cure,disability,vegetative state and mortality were counted after 30 d of admission.ResultsThe HLA-DR expressions in experimental group 1 and experimental group 2 after 1,3,7,14 d of admission were (28.11 ± 2.37),(26.45 ± 1.63),(27.75 ± 1.83),(27.15 ± 2.17) MCF and (29.34 ±2.07),(27.55 ± 1.63),(28.42 ± 1.94),(29.46 ±2.12) MCF,which had no statistical difference compared with that in control group [(29.18 ± 1.91 ) MCF](P＞ 0.05).The HLA-DR expressions in experimental group 1 and experimental group 2 after 1,3,7 d of admission and control group had statistical differences compared with those in experimental group 3 after 1,3,7 d of admission [(18.02 ± 1.78),(16.05 ± 1.97 ),(20.76 ± 1.65) MCF ] (P ＜ 0.05).The HLA-DR expressions in experimental group 1 and experimental group 2 after 14 d of admission and control group had no statistical significance compared with that in experimental group 3 after 14 d of admission [ (26.13 ± 2.15) MCF](P＞ 0.05).The infection rates of experimental group 1,experimental group 2 and experimental group 3 were 0,3.6％(1/28),82.8％(24/29),respectively,while the cure rates were 100.0％ (30/30),100.0％ (28/28),10.3％ (3/29),the disability rates were 0,0,41.4％ (12/29),the vegetative state rates were 0,0,20.7％ (6/29),and the mortality were 0,0,27.6％ (8/29).There was no statistical significance in the rates of infection,cure,disability,vegetative state and mortality between experimental group 1 and experimental group 2 (P＞ 0.05 ).While there was statistical differences in the rates of infection,cure,disability,vegetative state and mortality among experimental group 1,experimental group 2 and experimental group 3 (P ＜ 0.05).ConclusionsThe HLA-DR expression changes of patients with moderate and medium craniocerebral injury after 1,3,7,14 d of admission are not significant.The HLA-DR expression of patients with severe craniocerebral injury begins to decline from 1 d after injury,declines obviously at 3 d,increases from 7 d,returns to normal level at 14 d.The decline of HLA-DR expression in patients with severe craniocerebral injury is correlated with the infection,and predicts poor prognosis.

OBJECTIVE To explore a novel pH-sensitive fluorescent probe for in vivo tumor imaging. METHODS Zn5 were obtained in 140℃ after mixed with MeOH, water, Zn(NO3)2 · 6H2O, H4L and trimethylamine. The fluorescence spectra of Zn5 with the same concentration in different pH aqueous solutions were detected. And the stability of Zn5 was investigated by time dependent fluorescence emission spectra of Zn5 in BSA aqueous solution and 5.0% serum solution. Then, the cytotoxicity of Zn5 was detected by MTT assays. To clarify whether a similar fluorescence response occurs in biological organisms, HeLa cells were pretreated with probe Zn5 (0.5 μmol·L- 1) and fluorescence imaging were collected for targeting lysosomes in living cells because of lysosomes' acidic microenvironment. The A375 tumor-bearing mice were used to assess the imaging ability of Zn5 in vivo. Mouse tumor xenografts were established by injection of A375 cells with 2×106 cells per flank. Probe (1 μg·g-1) was administered to mice by injection. Images were obtained using IVIS Spectrum CT Imaging System. RESULTS There is a 11-fold intensity increasing as the pH values changing from 8 to 2. The almost unchanged emission intensities suggest Zn5 is stable in both BSA and serum. Zn5 has negligible cytotoxicity for HeLa, 293T and CHO-K1 cells. Zn5 can selectively display lysosomes in living cells. Both the 2D and 3D images in vivo distinguish the tumor from other tissues with good fluorescence contrast. CONCLUSION The high chemical stability, emission in the Vis/NIR range, pH sensitivity, a pKa located in the tumor pH range, and low toxicity make Zn5 is suitable for application as a pH- sensitive fluorescent probe for bio-imaging.

Objective To investigate the clinical significance of flow cytometry (FCM) assay in following up of the minimal residual disease (MRD) used for predicting relapse and guiding chemotherapy. Methods The clinical data of 43 acute leukemia patients diagnosed by MIC were collected in our hospital from 2005 July to 2008 June.Bone marrow aspirates were collected from 43 patients with newly diagnosed acute leukemia after induction therapy and during constimulation therapy. The cells with leukemia associated with immunophenotype were investigated using FCM, as immunologic target of MRD. Results MRD were detected earlier in predicting the relapse than those of the traditional bone marrow cells morphology assay by an average of 4-6 months. The results of the MRD following up: MRD was negative at CR in 26 cases, 6 cases relapse, 20 cases of them were kept negative during following up. MRD was positive in 17 cases at CR, 9 cases of them were relapse. 4 cases after intensified chemotherapy the MRD became negative and kept egative for more than one year. The MRD of the 43 cases at CR were divided into 3 groups, MRD less than 1×10-4 group (A group) MRD between 5×10-3 and 1×10-4 group (B group) and MRD above 5×10-3 group(C group). By chi square test. There was no statistical significance between A group and B group, but there was tatistical significance between B group and C group (P=0.02). Conclusion The application of FCM in detecting MRD has important clinical significance in predicting relapse and guiding chemotherapy.

Human rhinoviruses (HRVs) are the causative pathogens in more than half of viral upper respiratory tract infections. Currently, no antiviral agents that are active against HRVs are available for clinical use. Because only higher primates are susceptible to HRVs, the screening of new drug is most commonly based on the cell line model. In this study, isolated rabbit airway smooth muscles (ASM) tissue model has been established, and the airway responsiveness with different treatment has been examined. Relative to control tissues, the maximal constrictor (Tmax) response to ACh increased significantly 150% in ASM inoculated with HRV, and relaxation to isoproterenol has been attenuated to 63%. And the abnormal responsiveness can be inhibited in presence of pretreatment with several new compounds which have been exhibited effective anti-HRV activity on cell lines. The results demonstrate that the established ASM model will be applied to screening the anti-HRVs drugs.

More and more studies have shown that NOD-like receptor protein 3 (NLRP3) inflammasome has become the regulatory factor of inflammatory response and protective immunity, and the assembly and activation of NLRP3 inflammasomes are closely related to the anti-tumor immunity effect. Depending on the cell type and stimuli, activation of the NLRP3 inflammasome can induce immune cells to become polarized, hyperactive, or pyroptotic, releasing interleukin (IL)-1β and IL-18, which leads to cascade immune or inflammatory responses, and its role in tumor immunity has received extensive attention. Here, we review the mechanisms of the NLRP3 inflammasome enhancing CD8⁺ T cells-mediated anti-tumor immunity by inducing the pyroptosis of tumor cell, the pyroptosis or hyperactive state of dendritic cells (DCs), and the pyroptosis or polarization of the macrophages. Different anti-tumor immune roles of NLRP3 inflammasome activation in tumor cells and immune cells provide new directions for future research and may influence the development of next-generation immunotherapy.

Objective To explore the clinic application value of ultrasonography examination of optic nerve sheath diameter(ONSD) in brain injury.Methods From July 2008-June 2011,90 cases of brain injured patients were chosen as experimental group including light (A group),medium (B group),and heavy (C group) brain injured patients according to the admission GCS score ;50 cases of conventional physical examination and 90 cases of volunteers 50 in neurosurgical outpatient were chosen as control group.The ONSD of both groups were measured 3 mm behind the globe through orbital using color sonographic with different time after admission.3 times measurements were carried out for every optic nerve sheath.All client's ONSD mean and standard deviation were calculated.In 0.5 h after color dopplar ultrasound examination,lumbar vertebra puncturing measured intracranial pressure in different groups.Results After admission (1d,3 d,7 d,14 d),the ONSD of A group was (4.54 ±0.32)mm,(4.42 ±0.30)mm,(4.44 ±0.32) m,and (4.43 ± 0.25) mm,respectively; The ONSD of B groups was (4.48 ± 0.28) mm,(4.52 ± 0.24) mm,(4.46 ±0.28)mm,and (4.38 ±0.22)mm,respectively; The ONSD of C group was (5.67 ±0.35)mm,(6.36 ± 0.42) mm,(5.65 ± 0.23) mm,and (4.76 ± 0.35) mm,respectively.After admission (1 d,3 d,7 d,14 d),the intracranial pressure (IP) of A group was (82 ± 11) mmH2O,(79 ± 12) mmH2O,(90 ±15) mmH2O,and (86 ± 14) mmH2O,respectively; The IP of B group was (78 ± 15) mmH2O,(85 ± 10)mmH2O,(78 ± 16) mmH2O,(80 ± 11) mmH2O,The IP of C group was (225 ± 26) mmH2 O,(288 ± 23)mmH2O,(256 ± 23) mmH2O,(122 ± 18) mmH2O,respectively.Group D had the ONSD average of (4.58± 0.41)mm and IP of (88 ± 10)mmH2O after eyeball 3-mm place.No difference was found between A and B,A and D,or B and D (P＞0.05) ; A difference was found between A and C,B and C,or D and C (t =12.24～24.67,P＜0.01).Conclusions The ONSD and IP in light medium brain injured patients had no change.In patients with severe brain injury,IP changed with the time after injury,the ONSD increased with the IP,the ultrasonography examination of ONSD with the important value in the diagnosis and treatment can respond the IP increase,which is a non-invasion,convenient,fast,and feasible method for evaluation of cranial high pressure.

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.

OBJECTIVETo research the treatment effect of complex prescription of Chinese crude drug in BALB/c athymic mice with human liver cancer, which were built by Bel-7402.

METHOD48 male BALB/c athymic mouse models were built by Bel-7402 with an indirect method. After 24 hours of postoperation, the 48 athymic mice were distributed randomly into 4 groups which were treated by intragastric administration with complex prescription of Chinese crude drug that had been deliquated into 3 groups by the different density as the low, middle, and high and FT207 (Tegafur) for 4 weeks. At last, athymic mice were put to death and PTEN was detected in hepatic tissue, latero-cancer tissue and cancer tissue by immunohistochemistry (PowerVision Two-Step Histostaining Reagent).

RESULTAll of the 48 athymic mice survived 12 to 28 days (Ms 24 days) and every mouse with liver cancer demonstrated by dissection. The result of immunohistochemistry represents that the intensity of PTEN in latero-cancer tissue is the highest, and then the hepatic tissue, the lowest is cancer tissue, P < 0.01. It also represents that the intensity of PTEN in treatment groups (A, B, C) is more higher than the control group (D), P < 0.05 or P < 0.01, and group B is the highest in the treatment groups, P < 0.05 or P < 0.01. However, there is no significant statistic difference between group A and group C.

CONCLUSIONThe higher expression of PTEN in the laterocancer tissue can represent the protective reaction of stress of the organism. And anticancer effect of this complex prescription of Chinese crude drug relates to an eligible density of it. Mechanisms of this complex prescription of Chinese crude drug healing HCC may partially be explained by enhancing the expression of PTEN in liver.
