Electrophysiological studies have shown that the spinosolitary tract-dorsal column postsynaptic (SST-DCPS) neurons may project to both the dorsal column and solitary tract nuclei. In order to demonstrate the neurons morphologically, fluorescein dyes, PI and Bb, were injected into the dorsal column nuclei and the solitary tract nucleus respectively. A total 282 cells were found to be retrogradely labeled in the spinal dorsal horn in 10 adult rats. Of them, 51 (18%) cells were PI-Bb doubly labeled; 120 (43%) were PI labled alone; and 111 (39%) were Bb singly labled. Most of these double-labled cells were concentrated in laminae III-V. The existence of double projection neurons that project to both the dorsal column and solitary tract nuclei, namely the physiologically identified SST-DCPS neurons, is morphologically confirmed in the present study. These neurons may transmit information to both visceral and somatic sensory nuclei, indicating they may play an important role in the convergence of somato-visceral afferents.

Objective To study and observe the effect of astragalus membranaceus on serum free amino acids and chemokines in patients with rheumatoid arthritis. Methods 60 patients with rheumatoid arthritis in Lishui Hospital of traditional Chinese medicine from October 2014 to May 2016 were selected as the research object,and 60 patients were divided into control group and observation group with 30 cases in each group,according to the method of random number table,the control group were treated with conventional treatment of rheumatoid arthritis,the observation group were treated with astragalus mongholicus on the basic of control group,then the serum free amino acids and chemokines of two groups before the treatment and at 10th,20th,40th and 60th day after the treatment were respectively detected and compared. Results The serum free amino acids and chemokines of two groups before the treatment were compared, while the serum chemokines of observation group at 10th,20th,40th and 60th day after the treatment were all lower than those of control group,the serum free amino acids glutamic acid,asparagic acid and phenylalanine were all lower than those of control group,leucine,γ-aminobutyric acid, glycine and taurine were all higher than those of control group,the difference was statistically significant (P<0.05). Conclusion The influence of astragalus mongholicus for the serum free amino acids and chemokines of patients with rheumatoid arthritis is better,so its application in the patients with rheumatoid arthritis is higher.

Objective To establish the methods of isolating and culturing human ovarian endometriosis-derived microvascular endothelial cells (OEMEC).Methods The tissues of human endometriotic cyst of ovary were finely minced with scissors,then digested by collagenase Ⅰ,Ⅱ and trypsinethylene diamine tetraacetic acid (EDTA).The cells were purified by using centrifugation of 2000 r/min speed.OEMEC were identified by light microscope and transmission electron microscope observing CD34,FⅧ-Rag and Weibel-Palade in microvascular endothelial cells.Results The OEMEC grew as confluent monolayer like cobblestones under light microscope.CD34 and FⅧ-Rag were expressed strongly,and the percentages of CD34 and FⅧ-Rag positive cells were 91.4％ and 92.5％.Weibel-Palade bodies could be observed under transmission electron microscope.The time of cell doubling proliferation was 4.5 days.Conclusion The established system of isolating OEMEC would provide lab base for studying the mechanisms of angiogenesis in endometriosis lesions.

Objective To compare the efficacies and indications of locking compression plate (LCP) and external fixator plus Kirschner wires in treatment of complex intra-articular fracture of the dis-tal radius. Methods Ninety-eight patients with complex intra-articular fractures of the distal radius were treated with volar LCP or external fixator plus Kirschner wires, the efficacies of which were evaluated by comparing the grasping force and wrist function of the patients. Results All the patients were fol-lowed up for an average of 12.4 months, which showed fracture healing in all the patients. According to the wrist function assessment system of New York Orthopedic Hospital (1990), there was no statistical difference in the efficacy of LCP and external f'lxator plus Kirschner wires in treatment of types C1 or C2 fractures (P > 0.05), while the efficacy of external fixator plus Kirschner wires was significantly superior to that of LCP in treating type C3 fracture (P < 0.05). Conclusions For types C1 or C2 intra-articu-lar fractures of the distal radius, the efficacies of LCP and external fixator plus Kirschner wires are simi-lar, while the efficacy of external fixator plus Kirschner wires is superior to that of LCP in treating type C3 intra-articular fracture of the distal radius.

The battlefield rescuing unit of the current model is always restricted by some factors such as regional environments in wartime rescuing action and peacetime disaster relief, which can lead to failure of following and deploying action, so that wounded persons can not be rescued at the first time. Aiming at the special circumstances, a forward first-aid unit composed of five doctors and nurses should be established to give emergency medical rescue with rescuing emergent equipments and medicine packed in portable packages such as portable respiring machine, defibrillator and oxygen device at the battlefront. In this way, success rate of rescuing wounded persons would be increased obviously, while mortality rate and deformity rate would be decreased greatly.
