The theory of ascending and descending activities of qi is one basic theory that guides diagnosis and treatment of disease clinically. It has been esteemed by ancient physicians throughout their academic thinking and clinical diagnosis. As a kind of unbalanced disease in the whole body, the basic internal mechanism of tumor formation may be caused by unbalanced ascending and descending activities of qi. Better clinical efficacy is liable to get by applying the theory of ascending and descending activities of qi in cancer treatment. Therefore, we hope to provide a reference for clinicians from the following aspects: historical status and academic value of the theory of ascending and descending activities of qi, case examples and classical prescriptions.

As a characteristic tumor therapy in China, Chinese medicine (CM) plays an important position in comprehensive treatment of tumor. It's a critical issue of objective realization, analysis and evaluation of CM safety for scientific decision-making in tumor safe medication and it also is a pivotal issue which affects the international communication. The safety evaluation of CM includes three phases: pre-clinical safety evaluation, clinical trials (micro-dose studies and traditional clinical trials) and post-marketing CM safety assessment. The key point of evaluation should be distinguished among different stages and various types of CM (such as classic formulas, Chinese herbal extracts, etc). Emphasis should be given to chronic toxicity when evaluating oral Chinese herbal , microdose studies and quality control must be underlined while injection is evaluated and more attention should be pay to the dose-effect relationship and time-effect relationship when turned to toxic Chinese medicine , and so as for the toxicity grading study. Moreover, we should constantly improve CM safety assessment method in various stages of tumor treatment, such as introducing the concept of syndrome classification theory, bringing in metabonomics and real-world research method which are similar to the CM therapeutic concept. Most importantly, we must keep its own feature of CM theory when we learn the concept of safety evaluation from abroad. Actively exploring the anti-tumor medicine safety evaluation methods and strategies is of great significance for clinical and experimental research, and it can provide supportability platform to CM's international communication.

Background Researches have suggested that the defocus can induce the change of static visual acuity,but whether it produce influence on dynamic visual acuity is not clear.Objective This study was to investigate the impact of myopic defocus on static visual acuity and dynamic visual acuity and explore the essential difierence between static visual acuity and dynamic visual acuity. Methods Forty volunteers were enrolled in this trial.including 20 adults with the age of 27.4±1.64 years and 20 children with the age of 11.70+1.49 years.All the eyes of subjects received regular examined to excluded the eye disease with the best corrected vision of ≥1.0 D,astigmatism of ≤0.75 D and anisometropia ＜1.50 D.+1.00 D,+1.50 D,+2.00 D,+2.50 D slasses were ware respectively for the defocus on the foundation of full correction.Dynamic visual acuity was inspected by using selfmade DVA-I training software.and static visual acuity wag tested by static visual acuity chart (Precision Vision,CAT.NO.2125).This clinical trial complied with the Helsinki Declaration and obtained the approval of Ethic Committee of Wenzhou Medical College.Written informed consent was received from each individual prior to the protocol. Results The dynamic and static visual acuities were gradually decreased with the elevation of defocus (F=506.907,P=0.000).No significant differences were found between static visual acuity and dynamic visual acuity in adult or children at various defocus(P＞0.05).The regression linear analysis showed that a positive correlation between static visual acuity with defoeus(R2=0.819,t=26.72,P=0.000) or dynamic visual acuity with defoeus(R2=0.826,t=27.42,P=0.000).The slope and intercept between defocus with static visual acuity were steeper than that between defocus and dynamic visual acuity (slope:F=34.18,P=0.000;intercept:F=1005.56,P=0.001). Conclusion The effect of defocus on static visual acuity is different from that of dynamic visual acuity.It could be speculated that dynamic visual acuity is related not only to refractive systems but also other factor.

Objective To explore the value of dexamethasone(DEX) for neuronal cell injury and death by observing the effect of DEX on excitatory amino acid(EAA) and monoamine neurotransmitter in cerebral tissue of neonatal rat with hypoxia-ischemia.Methods Hypoxic-ischemic neonatal rat models were established,the levels of EAA and monoamine neurotransmitter in cerebral tissue were analyzed by using capillary electrophoresis and fluorospectrophotometry method.The rats were divided into 4 groups: small dose DEX group pre-treated with DEX(0.5 mg/kg) prior to hypoxia-ischemia,large dose DEX group pre-treated with DEX(10 mg/kg) prior to hypoxia-ischemia,HIE group and shamful operation group.Results The levels of EAA and monoamine neurotransmitter contents in HIE group were significantly higher than those in shamful operation group(P0.05).EAA contents of large dose DEX group greatly decreased compared with HIE group (P

A new experiment curriculum system of environmental microbiology was established centering on applied microbiology in environmental protection field and emphasizing on design and research experi- ments to motivate the students’ interests for the course, which helped them to improve their ability of think- ing independently and creatively as well as their practicing ability.

OBJECTIVETo seek the effective treatment for peripheral neuropathy induced by chemotherapeutic drugs.

METHODSSixty-four cases of peripheral neuropathy induced by Paclitaxel or Oxaliplatin were randomly divided into an acupuncture group and a medication group, 32 cases in each group. The acupuncture group was treated with therapeutic principle of dredging meridians and collaterals, tonifying qi and eliminating blood stasis, supplementing liver and kidney, nourishing blood and tendon. Hegu (LI 4), Taichong (LR 3), Zusanli (ST 36), Qihai (CV 6) and Quchi (LI 11) etc. were selected. The medication group was treated with intramuscular injection of Cobamamide. The neurotoxicity of two groups was compared with questionnaire of peripheral neuropathy induced by chemotherapeutic drugs before and after treatment.

RESULTSThe total effective rate for sensory nerve disorder of acupuncture group was 66.7% (20/30), which was superior to that of 40.0% (12/30) in medication group (P < 0.05).

CONCLUSIONAcupuncture is more effective than Cobamamide for treatment of peripheral neuropathy induced by chemotherapeutic drugs, especially for moderate and severe sensory nerve disorder induced by paclitaxel.

In modern medicine, DSA is a powerful technique in visualizations of blood vessels of X-ray images. In DSA, the most important way for motion correction is image registration. In this paper, a new approach to the registration is used. It is based on means of template matching according to a combined invariants-based similarity measure and TPS image warping. Furthermore it has been improved through practice. and tests have proved to remove the motion artifacts effectively and rapidly.

Sphingolipids, especially ceramide and S1P, are structural components of biological membranes and bioactive molecules which participate in diverse cellular activities such as cell division, differentiation, gene expression and apoptosis. Emerging evidence demonstrates the role of sphingolipids in hepatocellular death, which contributes to the progression of several liver diseases including ischaemia-reperfusion liver injury, steatohepatitis or hepatocarcinogenesis. Furthermore, some data indicate that the accumulation of some sphingolipids contributes to the hepatic dysfunctions. Hence, understanding of sphingolipid may open up a novel therapeutic avenue to liver diseases. This review focuses on the progress in the sphingolipid metabolic pathway with a focus on hepatic diseases and drugs targeting the sphingolipid pathway.

OBJECTIVETo investigate the effect of traditional Chinese medicine (TCM) on quality of life (QOF) and survival period in patients with progressive gastric cancer, and thus exploring its clinical efficacy.

METHODSTCM therapy applied in the 34 patients assigned in the TCM group (Group I ) included intravenous injection of Cinobufotalin, beta-elemene, or orally taking of anti-cancer Chinese herbs. The same TCM was also applied in the 36 of the combined treatment group (Group II), but in combined use of FOLFOX chemotherapeutic protocol. Twenty-one days was taken as one cycle and all the patients received 2 cycles of treatment.

RESULTSThe median survival period in group II was 31 months, while it was 30 months in group I; the 1-, 2-, 3-year survival rates in group II were 88.89%, 84.38% and 59.26%, and those in the group I were 82.35%, 71.43% and 65.00%, respectively with insignificant difference between the two groups (chi2 = 0.298, P > 0.05); QOF in group I was significantly superior to that in group II (P < 0.05), and the adverse reaction occurrence was significantly less in Group I than that in group II.

CONCLUSIONChinese medicine treatment can improve the QOF and prolong the survival period of patients with progressive gastric cancer with few side effects.
