To clarify the origin and application development of the traditional Chinese medicine " Zi-hua Qianhu" and " Qianhu", the medicinal literatures of past dynasties and modern researches were analysed. The plant Angelica decursivum was used as a substitute for traditional Chinese medicine "Angelica sinensis Radix" for a long historical period, it is used incorrectly for traditional Chinese medicine "Qianhu" due to origin research in modern times. The plant origin of "Qianhu" is Peucedanum praeruptorum. There are significant differences in clinical applications and chemical composition of the two drugs. The same efficacy description of "Zi-huaQianhu" and "Qianhu" could not stop "Zi-huaQianhu" used as "Qianhu" in practical application. Therefore, we need to further research for the plant A. decursivum, delimit its medicinal attribution.

To clarify the origin and development of the traditional Chinese medicine "Duhuo" and "Qianghuo" with medicinal literatures. Medical literatures of past dynasties were analysed and combined with the modern material. The "Duhuo" in Herbal writing Shen Nong Ben Cao Jing include traditional Chinese medicine "Duhuo" and "Qianghuo", "Qianghuo" was separated from "Duhuo" due to the distinguish of clinical application. The origin of "Qianghuo" is Notopterygium incisum and N. forbesii, However, The origin of "Duhuo" is very complex, Angelica pubescens f. biserrata as authentic "Duhuo" was used from Song Dynasty. "Qianghuo" was originated from "Duhuo".

0.05).The effective rate on relieving traditional Chinese medical syndrome was 95.0% in the treatment group and 73.3% in the control group,the difference being significant(P0.05).After treatment,the parameters of 24-h dynamic blood pressure were improved in both groups(P

Objective To investigate the transcription and protein expressions of chemokines CL16, CL12 and their receptors CR6, CR4 in first-trimester human cytotrophoblast cells and human choriocarcinoma cell line JAR. Methods Transcriptions of CR6, CL16, CR4, CL12 in purified first-trimester human trophoblast cells and JAR line were assessed by semi-quantitative RT-PCR, and protein expressions of CR6, CL16, CR4, CL12 were analyzed in primary cultured villous cytotrophoblasts (VCT), extravillous cytotrophoblasts (EVCT), JAR line and placentas by immunostaining. Results CR6 and CR4 were highly transcribed in primary cultured trophoblast cells with mRNA relative level of 1.12?0.25 and 1.08?0.11 respectively, and their ligands CL16 and CL12 were transcribed moderately with mRNA relative level of 0.89?0.11 and 0.78?0.10 respectively. It was demonstrated that CL16, CL12, CR6 and CR4 were expressed in primary cultured VCT, EVCT, JAR line and placentas by immunostaining. Conclusion The co-expression of CL16/CR6 and CL12/CR4 in trophoblast cells may play a role in the proliferation and differentiation of first-trimester trophoblast cells in a manner of autocrine.

As an important part of Chinese medicinal materials, uncommon-territorial herbs are also the most complex parts in the herbal medicine markets. Through years of investigation on the key markets of Chinese herbal medicine, the meaning of uncommon-territorial herbs, their historical evolution, origin and characteristics were clarified in this paper, and some countermeasures were put forward for its development.

OBJECTIVETo evaluate perioperative occult blood loss following total knee arthroplasty (TKA).

METHODSA retrospective analysis of 40 patients undergoing TKA was conducted to calculate the mean blood loss and occult blood loss according to Gross formula.

RESULTSThe mean total blood loss was 1538 ml in these cases with occult blood loss of 791 ml. In patients with autologous blood transfusion, the mean total blood loss was 1650 ml with occult blood loss of 786 ml. In patients without autologous blood transfusion, the mean total blood loss was 1370 ml with occult loss of 798 ml.

CONCLUSIONTKA often results in large volume of occult blood loss in the perioperative period which can not be fully compensated by autologous blood transfusion, and additional blood supply is needed for maintenance of the circulating volume.

OBJECTIVETo investigate the effect of Botulinum toxin type A (Botox) injection into the masseter muscle on mandibular development in rats.

METHODS12 28-day-old Wistar rats were divided into two groups as Botox group (n= 6) and control group (n = 6) which received anesthesia only. In Botox group, Botox was injected into the right masseter muscle, while only sterile saline into the left muscle. When the rats were 75-day-old, CT scan and 3D reconstruction were performed for cephalometry. The masseter muscles at both sides were weighed. Histologic study of masseter muscle and mandible was also performed.

RESULTSThe weight of right masseter muscle was (0.4575 +/- 0.0940) g in Botox group, and (0.8899 +/- 0.1030) g in control group (< 0.05). The mandibular height II and III was (10.8 +/- 0.8) mm and (9.5 +/- 0.6) mm in Botox group and (12.5 +/- 0.6) mm and (10.7 +/- 0.4) mm in control group, respectively (P < 0.05). The intergonial distance was (11.6 +/- 0.6) mm and (12.4 +/- 0. 6) mm in Botox and control group, respectively (P > 0.05).

CONCLUSIONSWhen the rats receive Botox injection into the masseter muscle at young age, the grown-up rats have a decreased mandibular height, but the mandibular length and intergonial distance are not affected.

Objective To evaluate the effect of denervation of masseter muscle on the development of mandible.Methods Twenty-four 28-day-old Wistar rats were randomly divided into operative(n=9),sham-operative(n=9)and control(n=6)groups.The main trunk and initial branches of the masseter nerve on the right side were resected in the operative group.The nerve was exposed,but not resected in the sham-oporative group.The control group was only anaesthetised.CT scan and 3D reconstruction were performed when the rats were 75 d old.Seven cephaiometric points were selected and digitized and selected 7 linear distances were measured.The rots were killed with an overdose of 10% chloral hydrate after the CT scan.Masseter muscles on each side were obtained and weighted immediately.Results The mass of the mandible of the operative side was significantly lighter than that of the non-operative side in the operative group(P<0.05).No significant variances on length of the mandible Ⅰ,Ⅱ and Ⅲ,and height of the mandible Ⅰ were found among the 3 groups(P>0.05).Compared with the control group,the operative group showed shorter height of the mandible Ⅱ and width of the mandible,and the operative and sham-operative groups showed shorter height of the mandible Ⅲ(P<0.05).Conclusion Changes on mandibular height Ⅱ and bilateral width after denervation of masseter muscle are noted and no influence on mandibular length is found.

Angelicae Sinensis Radix-Chuanxiong Rhizoma has the effects of nourishing and tonifying blood, activating blood and dissipating blood stasis, regulating menstruation and analgetic, which is commonly used Chinese medicine pair (CMP) in traditional Chinese medicine (TCM) clinic. It might be an independent formula, and is also usually used in many gynecological formulae and modern TCM prescriptions. This paper mainly analyzed and summarized the compatibility theory, bio-active constituents, compatibility effects and action mechanism, and clinical applications of the CMP, which can provide a basis for the depth research and development of the CMP.

Objective To evaluate the efficacy and feasibility of the coil-and-glue method for the reduction of lung volume in rabbit emphysema model.Methods Sixteen rabbits of emphysema model were divided into the occlusion group(n=10),in which both anterior bronchi were occluded using the coil-and- glue method,and the control group(n=6).The maximal static pressure of airway(P_(max)),peak expiratory flow(PEF),end-expiratory volume(EEV)and pressure of oxygen(PO_2)were measured at ante- emphysema,post-emphysema,1 week and 4 week after occlusion respectively.The expectoration(or migration)of coil and collapse of lung were also investigated.Results P_(max)was(20.0?1.3)and(17.1? 1.4)cm H_2O(1 cm H_2O=0.098 kPa)in the occlusion group at ante-emphysema and post-emphysema respectively.P_(max)was(19.2?1.4)cm H_2O in the occlusion group in the 1 week after the occlusion,while (17.1?1.5)cm H_2O in the control group(F=6.68,P
