This study was aimed to analyze compatibility rules of Chinese drugs and prescription design in the pre-vention and treatment of scleroderma. The database of scleroderma treated by Chinese medicine was set up. And then, association rules were used to analyze the prescription compatibility rules. The results showed the highest fre-quency of drugs in the treatment of scleroderma were Astragalus, Angelica sinensis and Salvia. The tonifying and re-plenishing medicinal, blood-activating and stasis-resolving medicinal and exterior-releasing medicinal were with the highest frequency. The commonly used formula in the treatment of scleroderma was Y ang-He decoction. For herbal groups, occurrence of the highest was the combinations of Ramulus Cinnamomi-Astragalus and Carthamus tinctorius L.-Astragalus. Three kinds of herbals were commonly coupled, such as Polygonum multiflorum Thunb. and Caulis Spatholobi with Salvia, P. multiflorum Thunb. and R. Cinnamomi with Salvia, P. multiflorum Thunb. and Astragalus with Salvia, prepared Radix Rehmanniae and Codonopsis with C. tinctorius L., prepared Radix Rehmanniae and Codonopsis with R. Cinnamomi, Codonopsis and Radix paeoniae rubra with R. Cinnamomi. Four kinds of herbals such as R. Cinnamomi, Glycyrrhiza uralensis Fisch., Astragalus and Codonopsis were commonly coupled. It was con-cluded that compatibility rules of Chinese medicine in the prevention and treatment of scleroderma laid the founda-tion for herbal medicine selection and prescription design.

In response to viral infection, RIG-I-like RNA helicases detect viral RNA and signal through the mitochondrial adapter protein VISA. VISA activation leads to rapid activation of transcription factors IRF3 and NF-κB, which collaborate to induce transcription of type I interferon (IFN) genes and cellular antiviral response. It has been demonstrated that VISA is activated by forming prion-like aggregates. However, how this process is regulated remains unknown. Here we show that overexpression of HSC71 resulted in potent inhibition of virus-triggered transcription of IFNB1 gene and cellular antiviral response. Consistently, knockdown of HSC71 had opposite effects. HSC71 interacted with VISA, and negatively regulated virus-triggered VISA aggregation. These findings suggest that HSC71 functions as a check against VISA-mediated antiviral response.

BACKGROUND:The use of mesenchymal stem cels in the field of tissue engineering for osteoarticular injury repair is a very promising tool since these cels are readily expandable and able to differentiate into chondrocytes. Abundant evidence suggests that microRNAs play critical roles in chondrogenic differentiation of mesenchymal stem cels.
OBJECTIVE:To observe the chondrogenic effect of human bone marrow mesenchymal stem cels transfected with lentiviral vectors bearing miR-221-3p/222-3p inhibition, thereby provding new strategies for cartilage injury.
METHODS: miRNA microarray technology was applied to detect microRNAs expression profiles at three different stages of chondrogenic differentiation induction after transforming growth factor-β3 treatment and verified by real-time fluorescence quantitative PCR (RT-qPCR). Human bone marrow mesenchymal stem cels were infected with lentivirus bearing miR-221-3p/222-3p inhibition. After co-suppressing the expression of miR-221/222-3p, cel counting kit-8 was used to determine the cel proliferation, the differentiation of bone marrow mesenchymal stem cels towards chondrocytes was verified by type II colagen protein expression through immunohistochemistry and glycosaminoglycan accumulation was also elevated by sarranine O staining. RT-PCR was used to detect type II colagen and aggrecan mRNA expression at 21 days of chondrogenic induction.
RESULTS AND CONCLUSION: The expression of miR-221-3p/222-3p was inhibited after Lv-miR221-3p/222-3p inhibition co-transfected into bone marrow mesenchymal stem cels. microRNA microarray and RT-qPCR results showed that the expression of miR-221-3p/222-3p was declined significantly at the anaphase of chondrogenic differentiation. The expression levels of chondrogenic markers, Aggrecan and type II colagen were significantly increased in the miR-221-3p/222-3p inhibition group and cel proliferation was also inhibited significantly compared with non-transduced cels or transduced with the empty lentiviral vector group. miR-221-3p/222-3p knockdown in bone marrow mesenchymal stem cels could inhibit proliferation but promote chondrogenic differentiation of bone marrow mesenchymal stem cels.

Objective To introduce the clinical experience and investigate venous drainage of distal- ly-based dorsal digital neurocutaneous flap for finger-pulp reconstruction.Methods From Mar.2004 to Oct.2005,18 patients with traumatic finger-pulp defect (>2cm) were treated by distally based dorsal ho- modigital neurocutaneous flaps.The flap measured 2 cm?2cm~3cm?4cm with the neuro-veno-adipal ped- icle 1cm wide and 2~3cm long.The pivot points were proximal to the PIP joints.The dorsal digital nerve was neurorrhaphied with the proper digital nerve of the recipient site.The dorsal digital vein was ligated at 1cm distal to the pivot point to prevent venous ingress.No venous anastomosis was performed.Results All the flaps survived but had some degrees of venous congestion and swelling,and 8 flaps developed tension blisters. In 13 flaps with follow-up more than 6 months,protective sensation was restored.Conclusion Dorsal digit- al neurocutaneous flap is simple and effective for finger-pulp reconstruction.Ligating the big superficial vein at the distal base to interrupt venous ingress,and allowing the proximal vein open and venous egress,can reduce flap congestion and swelling.

AIMTo study the effects and mechanism of naloxone on the febrile response in IL-1beta-induced fever rats.
METHODSThe fever model was established by intracerebroventricular injection of IL-1beta in rats. The effect of naloxone on the body temperature of feverrats was observed. The contents of cAMP in hypothalamus and AVP in VSA were detected.
RESULTSNaloxone alleviated IL-1beta-induced fever and the contents of cAMP in hypothalamus and AVP in VSA were correspondingly decreased (P < 0.01).
CONCLUSIONNaloxone could inhibit IL-1beta-induced fever in rats, and the mechanism might be due to inhibiting synthesis of cAMP in hypothalamus and promoting release of AVP in VSA.

The aim of the present study was to observe whether protein tyrosine kinase (PTK) within the nucleus tractus solitarius (NTS) was involved in the regulation of ventilatory responses of peripheral chemoreflex. The experiments were performed on anesthetized, immobilized and artificially ventilated rabbits. Peripheral chemoreflex was elicited by ventilating the animal with 10% O2-balance 90% N2. Changes in the peak amplitude and frequency of integrated phrenic nerve activity were observed. The ventilatory responses of peripheral chemoreflex following 0.1 microl microinjection within the NTS of either PTK inhibitor genistein (10 mol/L), AMPA glutamate receptor inhibitor CNQX (10 mol/L),or inactive PTK inhibitor daidzein (10 mol/L) were recorded. The results are as follows: Both genistein and CNQX attenuated the ventilatory responses of peripheral chemoreflex, while no changes occurred following daidzein. The amplitude of integrated phrenic nerve discharge and the phrenic burst frequency were decreased by (-21.77+/-6.93)% and (-24.70+/-7.61)% respectively after administration of genistein. CNQX resulted in similar decreases in the amplitude of phrenic nerve discharge (-27.13+/-7.63)% and the burst frequency (-21.34+/-4.88)%. In addition, the inhibitory effects of CNQX and genistein were the same whether they were applied alone or one after another, indicating that they had no cooperative effects. The results obtained suggest that PTK within the NTS regulates the peripheral chemoreflex control of respiration and that this regulation of PTK may be mediated through the phosphorylation of AMPA receptors in NTS neurons.

The commodity specification and grade of Chinese medicinal materials is a measure of the quality of traditional Chinese medicines (TCMs), which directly impacts on the safety and effectiveness of clinical medicines. It is an urgent problem to establish a set of standards which can both interpret the scientific connotation of the commodity specification and grade of Chinese medicinal materials and play a significant role on clinical medicines as well as markets. This paper reviews the research methods of the commodity specification and grade of Chinese medicinal materials such as sensory evaluation, chemical assessment, biological evaluation, and cited the applications of various methods for the classification of TCMs. It provides technical support for establishing standards of the commodity specification and grade of Chinese medicinal materials, and also constructs scientific basis for clinical rational drug use.
