The stable and controllable quality of decoction pieces is an important factor to ensure the efficacy of clinical medicine. Considering the dilemma that the existing standardization of processing mode cannot effectively eliminate the variability of quality raw ingredients, and ensure the stability between different batches, we first propose a new strategy for Chinese medicine processing technologies that coupled with individuation processed and cybernetics. In order to explain this thinking, an individual study case about different grades aconite is provided. We hope this strategy could better serve for clinical medicine, and promote the inheritance and innovation of Chinese medicine processing skills and theories.

Quality control is one of the key scientific tissues in the modernization of traditional Chinese medicines (TCM). In order to overcome the deficiencies of assessment indexes, including little systematization and quantification, as well as loose association with clinical efficacy and dosage, a new integrated method named controllability pyramid ( CP) is first proposed in this paper. In addition, some study cases are used to explain how this model is constructed. We hope the establishment of CP could promote the clinical-orien- ted integrated innovation research of TCM, and provide control strategy and technology examples for improving the quality of Chinese medicines and clinical efficacy.

Objective To explore the effect of complement activation on bone marrow mesenchymal stem cells (BMSCs)and evaluate the effect after transfection of complement regulatory proteins.Methods Bone marrow aspirate was harvested from 10 cases of patients suffered from fractures.Mesenchymal stem ceils were isolated,indentified cultured and then experimented in vitro.The complement cytotoxicity on the mesenchymal stem cells in autologous serum was measured by Europium cytotoxicity assay.The samples were divided into BMSCs group,BMSCs+ autologous human serum (AHS) group and BMSCs+ inactivated autologous human serum (iAHS) group.The complement membrane attack complex (MAC) deposited on the membranes was detected by flow cytometry.Finally,the cytotoxicity on BMSCs was measured after transfected with membrane complement regulatory proteins (mCRPs).All samples were divided into BMSCs with mCRPs untransfected group and BMSCs with mCRPs transfected group.Results More than 95％ of cells derived from bone marrow were identified to be mesenchymal stem cells through detection of cell surface markers by flow cytometry.The cytotoxicity of untreated cells was 0.41％± 1.48％.BMSCs harvested from the 10 patients all had cytotoxicity after incubated with autologous serum,and the cytotoxicity was 32.59％±2.73％,while cytotoxicity after incubated with complement inactivated autologous serum was 2.59％±3.08％,which was similar to control group.Complement attack complex (MAC) could be detected on the BMSCs incubated with autologous serum,which implied the complement activation.After transfection of mCRPs,the cytotoxicity of autologous serum on transfected cells was decreased.The cytotoxicity of untransfected cells (41.70％±4.47％) had significant difference compared to the cells transfected with CD55 (21.87％±2.19％),the cells transfected with CD59 (18.67％± 1.42％),and the cells transfected with CD46+CD55+CD59 (28.43％±2.14％).CD55,CD59 and CD46+CD55 +CD59 transfected groups could impair effectively the cytotoxicity from complement.However,the cytotoxicity impairment was less effective in CD46 transfected cells (39.30％±3.96％),which had no significant difference compared to untransfected cells.Conclusion Membrane complement regulatory proteins could effectively protect bone marrow mesenchymal stem cells from attacks by complement.

Good medicinal herbs, good drugs. Good evaluation method and indices are the prerequisite of good medicinal herbs. However, there exist numerous indices for quality evaluation and control in Chinese medicinal materials. However, most of these indices are non-interrelated each other, as well as having little relationship with efficiency and safety. The results of different evaluatior methods may not be consistent, even contradictory. Considering the complex material properties of Chinese medicinal materials, single method and index is difficult to objectively and comprehensively reflect the quality. Therefore, it is essential to explore the integrated evaluation methods. In this paper, oriented by the integrated evaluation strategies for traditional Chinese medicine quality, a new method called integrated quality index (IQI) by the integration of empirical evaluation, chemical evaluation, and biological evaluation was proposed. In addition, a study case of hypertoxic herb Aconitum carmichaelii Debx. was provided to explain this method in detail. The results suggested that in the view of specifications, the average weight of Jiangyou aconite was the greatest, followed by Weishan aconite, Butuo aconite, Hanzhong aconite, and Anxian aconite; from the point of chemical components, Jiangyou aconite had the characteristic with strong efficacy and weak toxicity, next was Hanzhong aconite, Butuo aconite, Weishan aconite, and Anxian aconite; taking toxicity price as the index, Hanzhong aconite and Jiangyou aconite have the lower toxicity, while Butuo aconite, Weishan aconite, and Anxian aconite have the relatively higher one. After the normalization and integration of evaluation results, we calculated the IQI value of Jiangyou aconite, Hanzhong aconite, Butuo aconite, Weishan aconite, and Anxian aconite were 0.842 +/- 0.091, 0.597 +/- 0.047, 0.442 +/- 0.033, 0.454 +/- 0.038, 0.170 +/- 0.021, respectively. The quality of Jiangyou aconite is significantly better than the others (P < 0.05) followed by Hanzhong aconite, which is consistent with the traditional understanding of genuineness. It can be concluded that IQI achieves the integrated control and evaluation for the quality of Chinese medicinal materials, and it is an exploration for building the good medicinal herbs standards. In addition, IQI provides technical supports for the geoherbalism evaluation, selective breeding, the development of precision decoction pieces, high quality and favourable price in market circulation, and rational drug use.

OBJECTIVEImpulse noise was adopted in adult rats to built acute deafferent animal model. Differential proteomics techniques were applied to detect the changes of protein expression in the auditory cortex before and after the noise exposure.

METHODSThirty adult SD rats were divided into three groups: normal group, rats with acute noise exposure and rats 28 days recovery after noise exposure (n=10/group). All animals were exposed to impulse noise at 156 dB for 50 pulses with a rise-time of 100 µs and duration of around 0.25 ms. ABR was used to evaluate the auditory function. The two-dimensional gel electrophoresis (2-DE) and matrix-assisted laser desorption ionization time-of-flight mass spectrometer (MALDI-TOF-MS) were used to identified the differential protein expression.

RESULTSCompared with the normal group, ABR thresholds were found significantly increased at 2, 4, 8, 16, 32 kHz (P<0.05) in the acute and recovery groups. There was a 40-60 dBSPL ABR threshold shift at all tested frequencies immediately after impulse noise exposure. There was a partial recovery of ABR thresholds at 7 day to 28 days after impulse noise exposure. In addition, it seemed that the thresholds were rather stable and no further ABR threshold recovery was observed from 14 day to 28 days after the impulse noise exposure. Using differential proteomic techniques, 36 spots containing 27 proteins were revealed and identified in auditory cortex. Those proteins are related to cytoskeleton, neurotransmission, energy supply, mitochondrial function and synaptic remolding.

CONCLUSIONSImpulse noise may influence the function of microtubule transport and cell metabolism, there after affect the neurotransmission of auditory neurons. The compensatory changes such as pre- and postsynaptic or such related functional changes may also happen in auditory cortex after the deafferentation treatment.

In this paper, Rhodiolae Crenulatae Radix et Rhizoma extract,with high hygroscopic,was selected as research model, while lactose was selected as modifiers to study the effect of the grinding modification method on the hygroscopic. Subsequently, particle size distribution, scannin electron microscopy, infrared spectroscopy and surface properties were adopted for a phase analysis. The results showed that the modified extract, prepared by Rhodiolae Crenulatae Radix et Rhizoma extract grinding 5 min with the same amount of lactose UP2, which hygroscopic initial velocity, acceleration, and critical relative humidity moisture were less than that of Rhodiolae Crenulatae Radix et Rhizoma extract and the mixture dramatically. In addition, compared with the mixture, the size distribution of modified extract was much less, the microstructure was also difference, while the infrared spectroscopy and surface properties were similar with that of lactose. It is the main principle that lactose particle adhered to the surface of Rhodiolae Crenulatae Radix et Rhizoma extract after grinding mofication to decress the moisture obviously.

The specification of decoction pieces and quality uniformity are the important factors to influence the efficacy of clinical medicine. Considering the deficiency of diversity, poor quality uniformity and confusion of decoction pieces specifications, we first propose a new idea of precision decoction pieces (PDP) based on clinical demands and fresh-processed technology. In order to explain the idea, a study case of aconite SUP is provided, including the optimized specification design, processing technology, extraction effects, quality uniformity, and toxic and efficacy variation and so on. The results showed that preparing 5 mm PDP by fresh-cutting is rather simple and practicable, with high efficiency and large yield; then, this technology could significantly decrease the ingredients loss and increase the efficacy components; moreover, it was helpful for achieving the quality uniformity and best extraction effects. This work revealed the quality superiority of PDP, and provided a good strategy and example for the standard of decoction pieces specification and modernization of processing technology.
