Objective To observe the effect of Professor Deng Tietao’s Brain-strengthening Recipe 1 on learning and memory abilities of rats with vascular dementia, and to explore its molecular biology mechanism. Methods The vascular dementia rat model was established by permanent occlusion of the bilateral arteria carotis communis. Sixty male SD rats were randomly divided into 5 groups, namely sham-operation group, model group, nimodipine (5.4 mg·kg-1·d-1) group, and high-and low-dose Chinese medicine groups (57.6 and 14.4 g·kg-1·d-1, respecitvely) . After medication for 30 days, the learning and memory abilities were evaluated by Morris water maze test. The histological changes of the rat hippocampal tissues were observed after HE staining, and the mRNA expression of N-methyl-D-aspartate receptor subunit 2B ( NR2B) in rat hippocampus was measured by real-time fluorescence quantitative polymerase chain reaction (RT-PCR) . Results The water maze test results showed that the escape latency of the rats in the sham-operation group was significantly decreased on the third day, and was significantly decreased in the high-dose Chinese medicine group on the fourth day ( P<0.05 compared with the model group). The results of spatial probe test showed that the times of rats passing through the platform within 60 seconds were significantly higher in high-dose Chinese medicine group ( P<0.01compared with the model group) , but the time for rat staying at the quadrant of the platform in the other four groups did not differ from that in the model group ( P>0.05). HE staining results for the model group were presented as the absence of neural cells in hippocampus CA1 region, karyorrhexis of nerve cells, indistinctness of nuclear membrane, disappearance of nucleolus, shrinkage of nerve cells, increase of cytoplasm acidophily, and reactive hyperplasia of astrocytes. And in the hippocampal CA1 region of high- and low-dose Chinese medicine groups, the injured neural cells were found, and the lesions were slighter than those of the model group. Compared with the model group, the mRNA expression of NR2B was increased in nimodipine group and high-dose Chinese medicine group ( P<0.05) . The mRNA expression of NR2B showed a increasing trend in low-dose Chinese medicine group, but the differences were insignificant compared with that of the model group ( P>0.05). Conclusion Brain-strengthening Recipe 1 has obvious effects on improving the learning and memory abilities of vascular dementia rats, and the therapeutic mechanism is associated with reduction of the degree of neuronal damage in hippocampus and with the upregulation of the mRNA expression of NR2B.

3.Analysis on Clinical Application and Significance of Skin Allergy Test of TCM Injections
Chinese Journal of Information on Traditional Chinese Medicine 2016;23(11):121-123
Type I allergic reaction is the most common and serious one in the adverse drug reactions (ADR) of TCM injections. Skin test can be used to predict the occurrence of allergic reactions, which is a simple and effective method for safe use of TCM injections. To a certain extent, it can reduce ADR of medicine and ensure the safety of clinical medication. However, the medicine instructions of TCM injections that clearly point out the need for skin test are few, and there are many problems of skin test in clinical practice. For example, lack of systematic research on skin test, no uniform standard for clinical judgment, lack of diagnostic reagents and proprietary methods of skin test. Therefore, specifications for clinical skin test of TCM injections are needed to provide guarantee for the safe use of TCM injections.

OBJECTIVETo observe preventive and therapeutic effects of Tanshinone IIA (T II A) on oxaliplatin induced peripheral neuropathy (OlPN) and to explore its effects on the expression of calcitonin gene related peptide (CGRP) and never growth factor (NGF).
METHODSTotally 36 phase II - III patients with malignant tumor of digestive tract undergoing chemotherapy program with oxaliplatin, were equally assigned to the T II A group (using THA at 80 mg/day 1 day before oxaliplatin chemotherapy for 3 successive days) and the control group (using chemotherapy program with oxaliplatin alone) by segmented randomization. After 4 cycles of chemotherapy, the incidence degree and incidence of OlPN were evaluated. Sensory nerve conduction velocity (SNCV) and motor nerve conduction velocity ( MNCV) were tested by EMG evoked potential device. Serum levels of CGRP and NGF were also detected in the two groups before and after chemotherapy. The correlation of serum levels of CGRP and NGF to OIPN was assessed using linear correlation analysis.
RESULTSAfter chemotherapy the OlPN incidence was 27.8% (5/18 cases) in the T II A group, obviously lower than that in the control group (55.6%, 10/18 cases; P < 0.05). Compared with before treatment in the same group, SNCV and MNCV of common peroneal nerve were slowed down, serum NGF levels decreased, and serum CGRP levels obviously increased in the two groups (all P < 0.05). Compared with the control group after treatment, SNCV and MNCV of common peroneal nerve were obviously accelerated, serum NGF levels increased, and serum CGRP levels obviously decreased in the THA group (all P < 0.05). Results of linear correlation analysis indicated serum NGF level was negatively correlated with peripheral neuropathy (PN), serum CGRP expression was positively correlated with neurotoxicity (P < 0.05).
CONCLUSIONT II A could reduce the incidence of OlPN, which might be associated with inhibiting the expression of CGRP and up-regulating NGF activities.

Aim To investigate the effect of intrathecal injection of CCR2 antagonist on pain behaviours,spinal astrocytes activation in the spinal cord in a rat model of bone cancer pain. Methods Forty female SD rats weighing 150 ~180 g were randomly divided into five groups ( n=8 each ):(Ⅰ) sham group;(Ⅱ) sham +RS102895 group;(Ⅲ) bone cancer pain group;(Ⅳ) bone cancer pain + DMSO group;(Ⅴ) bone cancer pain+RS102895 group. Rats received i. t. injections of either RS102895 (3 g·L-1 ) 10 μl or 10%DMSO 10 μl at the time of 10-12 days after the operation. Bone cancer was induced by intra-tibial inoculation of 1 × 105 Walker 256 breast cancer cell. Mechanical hind paw withdrawal threshold test was performed one day before and at 3rd,6th,9th, 10th,11th and 12th days after surgery. Immunofluorescence was used to observe the activation of the spinal astrocytes. Results Compared with group Ⅰ, the rats in bone cancer pain group appeared obvious mechanical hyperalgesia (Ⅲ、Ⅳ、Ⅴ) ,the volume,shape and mean optical den-sity ( MOD) of spinal astrocytes could be seen obvious-ly increased,groupⅡhad no obvious statistical signifi-cance (P>0. 05). Compared with group Ⅳ ,i. t. in-jections of RS102895 increased the paw mechanical withdrawal threshold, suppressed the action of astro-cytes,reduced the MOD of spinal astrocytes. Conclu-sion CCR2 might participate in the formation of bone cancer pain via activating spinal astrocytes. CCR2 will be a potential target for the treatment of bone cancer pain.
