[Shen cha zheng ji yan fang (Inspection of the Collection of TCM Proved Prescriptions) , the first official collection of proved prescriptions in Modern China].

Yan Xishan, the local ruler of Shanxi Province in modern period, claiming that the folk TCM prescriptions should be collected, inspected and maintained because of its definite effect. The government of Shanxi Province provided a lot of resources in collecting TCM proved prescriptions since 1929. The TCM Improving Society of Shanxi made more effort on the inspecting process, with a reasonable incentive system and standardized methods established. As a result, the Shen cha zheng ji yan fang (Inspection of the Collection of TCM Proved Prescriptions) was published, characterized by the principles of "cheap, convenient and effective" . It was the beginning of official collection and collation of TCM proved prescriptions in modern China.

Relieving effect of Artemisia argyi aqueous extract on immune stress in broilers.

This experiment aimed to investigate the relieving action of Artemisia argyi aqueous extract (AAE) on immune stress in broiler chickens. A 2 × 2 factorial design was used to test the effect of 2 dietary treatments (adding 0 or 1000 mg/kg AAE) and 2 immune stress treatments (injecting saline or lipopolysaccharide (LPS)). A total of 96 one-day-old Arbor Acres (AA) broilers were randomly divided into four treatment groups with six replicates, four birds in each replicate. Broilers in Treatment groups 1 and 2 were fed with the basal diet, and those in Treatment groups 3 and 4 were fed with the experimental diet supplemented with 1000 mg/kg AAE. On days 14, 16, 18 and 20, broilers in both Treatments 1 and 3 were injected intra-abdominally with LPS solution at the dose of 500 µg LPS per kg BW with the LPS dissolved in sterile saline at a concentration of 100 µg/ml, and those in Treatments 2 and 4 were injected intra-abdominally with equal amount of sterile 0.9% saline. Blood samples were collected on days 21 and 28. The results showed that dietary supplementation of AAE prevented reductions in average daily gain (ADG) and average daily feed intake (ADFI) of broilers caused by LPS on d 15-21. On day 21, the injection of LPS increased serum adrenocorticotropic hormone (ACTH) and corticosterone (CORT); meanwhile, feeding AAE reduced the rise of CORT caused by LPS. Immune parameters such as interleukin-1 (IL-1), interleukin-2 (IL-2), interleukin-6 (IL-6), immunoglobulin G (IgG) and immunoglobulin A (IgA) were also improved by LPS, but the content of IL-2 and IgG in broilers fed with AAE diet was significantly lower than that of broilers fed with control diet. All the data suggested that diets supplemented with AAE could relieve the immune stress response of broilers.

[The first official organization of traditional Chinese medicine in modern China-TCM Improvement Research Association].

In modern China, most of the mass organizations of traditional Chinese medicine (TCM) were civilian and established by the individuals with self support financially.The TCM Improvement Research Association of Shanxi Province was the first official TCM organization in modern China. For the purpose of ruling and recognition of TCM, Yan Xishan, the chief executive of Shanxi province, gave a full support to its creation, development, and operation of the Association with the military and political officials in the government served as part-time staff members of a few of important position in the Association. The Association was given funding and policy support by official ways. The local administrative departments cooperated with the Association affairs actively. Because of the stable organization and the abundant fund, the TCM Improvement Research Association developed quickly and steadily. As a result, the Association had been playing an important and increasing role in academic research, TCM education, medical and epidemic prevention and so on. It had become one of the great national TCM academic societies with prolonged existence. As an official Association, it was characterized with a dual property: a better foundation for development and little independency.

Ca/Mg infusions for the prevention of oxaliplatin-related neurotoxicity in patients with colorectal cancer: a meta-analysis.

BACKGROUND: Oxaliplatin-related neurotoxicity is the main limitation for its continuation in adjuvant and palliative chemotherapy for patients with colorectal cancer. The purpose of this meta-analysis was to determine the efficacy of calcium and magnesium (Ca/Mg) infusions in oxaliplatin-induced neurotoxicity. METHODS: Two independent authors conducted database searches of the literature to find clinical-controlled trials analyzing Ca/Mg infusions in oxaliplatin-induced neurotoxicity. The keywords used to search were oxaliplatin, neurotoxicity, calcium, magnesium, neuropathy, and peripheral. Clinical studies that included at least one primary or secondary event were eligible for the analysis, where primary events were incidences of acute and cumulative neurotoxicity, and secondary events were the total doses and cycles of oxaliplatin, response rate (RR), overall survival (OS), and progression-free survival (PFS). Odds ratios (ORs) and weighted mean differences (MD) were analyzed using models of fixed and random effects. RESULTS: This meta-analysis comprised four prospective randomized clinical trials and three retrospective clinical trials involving 1170 colorectal cancer patients, of which 802 received Ca/Mg infusions (Ca/Mg group) and 368 did not (control group). According to the National Cancer Institute-Common Terminology Criteria for Adverse Events, the incidence of grade 3 acute neurotoxicity in those who received Ca/Mg was significantly lower than that of the control group (OR=0.26; 95% confidence interval (CI), 0.11 to 0.62; P=0.0002). The total rate of cumulative neurotoxicity, and that of grade 3 in particular, was significantly lower in the Ca/Mg group than in the control group (OR=0.42; 95% CI 0.26-0.65; P=0.0001; OR=0.60; 95% CI 0.39-0.92; P=0.02, respectively). The differences in total doses and cycles of oxaliplatin were also significant between the Ca/Mg and control group (MD=246.73 mg/m2; 95% CI 3.01-490.45; P=0.05; MD=1.55; 95% CI 0.46-2.63; P=0.005, respectively). No significant differences were found in median PFS (MD=0.71 month; 95% CI -0.59-2.01; P=0.29), median OS (MD=0.10 month; 95% CI -0.41-0.61; P=0.70) or RRs (OR=0.82; 95% CI 0.61-1.10; P=0.18). CONCLUSION: Ca/Mg infusions tend to decrease the incidence of oxaliplatin-induced acute and cumulative neurotoxicity and thus enhance patients' tolerance to oxaliplatin, without significantly altering the efficacy of chemotherapy.
