Objective To study the feasibility of the treatment of tubule pregnancy by interventional technique. Methods By using Seldinger′s method, 40 cases of tubule pregnancy received superselective angiography of uterine artery,followed by perfusion of methotrexate (MTX) through the catheter and embolization of uterine artery with gelatin sponge. The concentration of serum ? HCG, the change of pelvic cavity, and the open condition of oviduct were regularly monitored postoperatively. Results Angiographic findings of tubule pregnancy were classified into 3 types. Type Ⅰ, no abnormal vascular appearance were found in 3 cases (7.5%). Type Ⅱ, patchy vascular staining of villi in parauterine area was observed in 4 cases (10.0%). Type Ⅲ, a round vascular staining of villi surrounded by small blood vessels in parauterine area occurred in 33 cases (82.5%). The cure rate in total 40 cases achieved 97.5% (39/40). After treatment, the mean time that the serum ? HCG concentration returned to normal was (7.66?2.01) d and the mean time that the menstruation returned to normal was (29.78?7.14) d. In 21 cases who hoped their fertility remaining intact, the oviduct were verified open by hysterosalpingography (HSG) in 20 cases, the open rate was 95.24%. Conclusion The treatment of tubule pregnancy by interventional technique was proved no harmful effect to reproductive organs and would expect to preserve fertility. This method could resolve the difficult problem of celiac hemorrhage which making conservative treatment impossible and internal hemorrhage happened in the course of traditional conservative therapy leading to treatment failure finally. This method might be a new conception and a choice to treat tubal pregnancy through artery.

Objective To evaluate a modified liver hanging maneuver(retrohepatic tunnel of the IVC) in patients undergoing hemihepatectomy.Methods Twenty-four patients undergoing hemihepatectomy were divided into two groups:modified liver hanging maneuver group(n=12)and Pringle's maneuver group(n=12).The amount of intraoperative bleeding,operation time,postoperative liver function,liver function recovery and complications were compared between the two groups.Reset All operation were performed successfully and there were no difference in the time of operation etween the two groups.There was a difierence in the amount of mean intraoperative blood loss between the two groups.It was(160±40)ml in liver hanging group and(560±120)ml in Pringle's group(P＜0.01).Liver function recovery measured on postoperative day 3 and day 7 was better in liver hanging groupthan that in Pringle's group(P＜0.01).The volume of postoperative peritoneal serous fluid dranage was significantly less in liver hanging group(P＜0.01).Conclusion The modified liver hanging maneuver is useful for hemihepatectomy.

Objective To study the molecular characters of porA and porB genes which encode outer membrane proteins (OMP), and predominated clonal complex of Neisseria meningitidis isolates from Guangdong province. Methods Eighteen Neisseria meningitidis isolates from Guangdong province during year 1967 to 2007 were recovered and reconfirmed by API NH biochemical system, and serogrouped by antiserum. The characters of porA and porB gene were analyzed by DNA sequencing. The allele profiles and the sequence types (ST) were determined by multilocus sequence typing (MLST). Based on their allelic profiles, the evolution relationship was analyzed by PHYLIP software. The predominant clonal complex was determined through comparing with the information of reference strains from the PubMLST database. Results For porA gene, type 20 was more frequently in the variable region (VR) 1 and type 9 in VR2 before year 2004. However, for porB gene, type 4 was more frequently in VR Ⅰ, type7 in VR Ⅳ, type 11 in VR Ⅴ,and type 10 in VR Ⅵ, respectively. The multi-types character was presented in VR Ⅴ and VR Ⅵ after2004. VR Ⅶ and VR Ⅷ can not be found among all the isolates except for one W135 isolate in 2007. Among the seven housekeeping genes, the polymorphism of abcZ was the lowest one with 4 allele numbers, while pgm was the highest one with 13 allele numbers. The predominant clonal complex was ST-5 before 2004. The ST-4821 clone complex appeared in 2004 and caused cases every year since then. More important, highly invasive ST-11 clonal complex firstly appeared in Guangdong in 2007. Conclusion The molecular characteristic of OMP genes presents polymorphism for the Neisseria meningitidis isolates from patients in Guangdong province during 1967 to 2007. ST-5 is the predominant clonal complex before 2004 and the highly invasive clonal complex is circulating in recent 3 years. It suggests that the surveillance based on laboratory should be further enhanced.

In temporomandibular disorders (TMD), pain takes place when neuropeptides stimulate synovial tissue to produce several cytokines such as interleukin (IL)-1β, IL-6 and tumor necrosis factor (TNF)-α, which activate neurons and glia of synovial membrane at the bilaminar regions of temporomandibular joint (TMJ). It has been reported that, after neurogenic differentiation, the synovial mesenchymal stem cells (SMSCs), deriving from TMJ, possess the same cytological features as the neuronal cells. This study examined the ability of substance P (SP) and calcitonin gene-related peptide (CGRP) to stimulate SMSCs and neurogenic SMSCs secreting inflammatory cytokines during TMD, evaluated the mutual effects of inflammatory cytokines and neuropeptides and tested the analgesic effect of hyaluronic acid (HA). The levels of IL-1β, IL-6 and TNF-α in SMSCs and neurogenic SMSCs in the presence of neuropeptides were measured by ELISA. SP and CGRP produced by SMSCs and neurogenic SMSCs were determined by RT-PCR and Western blotting. The results showed that the expression of SP and CGRP was significantly enhanced in the neurogenic SMSCs in response to IL-1β, IL-6 and TNF-α, and the effect was remarkably inhibited by HA. IL-1β, IL-6 and TNF-α, in return, could be enhanced in the neurogenic SMSCs upon stimulation by SP and CGRP. Neuropeptides and inflammatory cytokines might work mutually on the TMD pain. The HA-mediated analgesic effect may be implicated in the inhibition of SP and CGRP expression in neurogenic SMSCs.

Objective To investigate the effect of C peptide on tubulointerstitial oxidative stress injury in rats with diabetic nephropathy (DN) induced by streptozotocin (STZ). Methods Wistar rats with DN induced by STZ were randomly divided into control group and C peptide group. All rats were treated via intraperitoneal micro-osmotic pump. Normal Wistar rats at the same age were used as the normal group. Blood glucose and24 h urinary albumin were measured before treatment and every 4 weeks during treatment period. After 12 weeks of treatment, the expression of transforming growth factor - β1 (TGF - β1) in renal tubulointerstitium was detected by immunohistochemical staining. Fresh tubulointerstitial tissue homogenate was harvested and the activity of superoxide dismutase (SOD) was detected in WST-1 method, the content of malondialdehyde (MDA) was detected in TBA method, and the expression of protein kinase A (PKA) mRNA was detected by Real-time PCR. Results Levels of blood glucose, 24 h urinary albumin, MDA content and the expression of TGF-β1 were higher in the control group than those in the normal group, while SOD activity decreased and PKA mRNA was downregulated. C peptide treatment did not change blood glucose level but slowed down the increasing of 24 h urinary albumin, reduced the tubulointerstitial TGF-β1 expression and MDA content, increased the SOD activity and upregulated the PKA mRNA expression. Conclusions C-peptide can decrease the tubulointerstitial oxidative stress in DN rats by activating PKA pathway and then improve tubulointerstitial fibrosis and attenuate proteinuria.

Shanghai University of TCM was the first Chinese medicine university that established field-grade experimental teaching center in China.And both of the Chinese medicine and Chinese herbs experimental teaching centers became national experimental teaching demonstration centers.There is general improvement in laboratories conditions,so the experimental teaching team building is the critical factor of improving experimental teaching quality.The experimental teaching team of Shanghai University of TCM consists of excellent teachers as its backbone,and lecturers and technicians from fields in traditional Chinese medicine Chinese herbs and clinical practices.The team members cooperate with each other by setting up experimental teaching research groups to improve teaching quality,which plays an important role in building experimental teaching demonstration center.
