Objective To evaluate the effect of selective angiography and embolization for the pa-tients with haemodynamically unstable pelvic fracture. Methods Sixty-two patients with haemodynami-cally unstable pelvic fracture were treated in our hospital from 2002 to 2008. Their pelvie fractures were classified on the basis of their X-ray and CT data. By AO classification, there were 2 cases of type A2, 6 B1, 9 B2, 8 B3, 16 C1, 13 C2, and 8 C. There were 6 cases of open injury (by Gustilo classification, 1 type Ⅱ and 5 type Ⅲ). Of the 46 eases of multiple injuries, 12 had shock. While active fluid infusion and vascular medication were conducted, the angiograph was done for all patients, 59 of whom also received embolization. Results Seventy-nine angiographs were performed for the 62 cases, and 12 of them received more than twice angiographa. Exams revealed that 32 patients had suffered injury to more than 2 arteries. The injured arteries were sequentially superior gluteal artery, iliolumbar artery, lateral sacra] artery, obturator artery, inferior gluteal artery, internal pudendal artery, internal iliae artery and external lilac artery. Of the 59 cases of embolization, 56 were successful. Seven patients died due to severe abdominal organ injury. Forty-five patients got an average follow-up of 14 months (range, 6 to 52 months) . No severe complications were no-ticed. Conclusions Selective angiography and embolization is an effective intervention for patients with haemodynamically unstable pelvic fracture. It is mandatory to conduct recurrent angiographic embolization for patients with multiple artery injuries or delayed artery injuries.

Objective To investigate the strategy to improve successful treatment for severe acute pancreatitis (SAP). Methods The study period was divided into from 1992 to 2000, and from 2001 to 2009.The patients during these two phases were comparable as regard to sex and age. Results The proportion of patients received anti-inflammatory medications from 2001 to 2009 was 88.7% (94/106), medications which can improve the pancreatic microcirculation were used in 93.4% (99/106), early enteral nutrition was used in 58.5% (62/106), medications which can protect intestinal barrier function were used in 98.1% ( 104/106),all these parameters were significantly higher than those (22.4%, 19/85; 43.5%, 37/85; 29.4%, 25/85;17.7%,15/85) from 1992 to 2000. Also from 1992 to 2000, more patients underwent operation such as basin-shaped open drainage, pancreatic necrosis debridement. While more patients underwent operation such as laparoscopic drainage, CT or B-ultrasound guided percutaneous drainage from 2001 to 2009. The proportion of patients underwent surgical treatment decreased from 56.5% (48/85) to 32. 1%(34/106); the survival rate increased from 68.8% to 84.0%. Conclusions The research progress of medications was the foundation to improve successful treatment for SAP. Operation was an important option during SAP therapy. The individualized treatment was beneficial to improve successful treatment for SAP.

Objective To evaluate the effect of different degrees of pubic symphysis diastasis on the stress distribution of posterior pelvic ring. Methods Eight embalmed pelvis and articulated proximal 1/3 of the femurs were harvested for this study. The samples were positioned as both legs standing straight and loaded to 600 N on the on the CSS-44020 biomechanical machine. The strain gages were adhered to 38 sites distributed symmetrically on the two sides of sacroiliac joint, anterior sacrum and posterior ilium. The strain gages were connected to WS3811 digital strainometer to record strain changes of the intact pelvic ring and at 1,2, 2.5 cm of pubic symphysis diastasis. Results Elastic changes occurred in the cortical bone of the pelvis under 600 N load. The symmetrical sites had similar strain changes without significant difference in the intact pelvic ring and at 1,2, 2.5 cm of pubic symphysis diastasis ( P ＞0.05 ). The sites with more strain changes were distributed on the iliofemoral arch in the intact pelvis.The strain changes were increased significantly frona the posterolateral sites to the iliofemoral arch. But the strain changes on the iliofemoral arch were decreased significantly during pubic symphysis diastasis.Conclusion The conduction of vertical load runs along the sacrofemoral arch in the intact pelvic ring and redistributes posterolaterally during pubic symphysis diastasis.

This study aimed at unfolding the therapeutic effects of freeze-dried powder separated from Shuang Xia decoction (SXD) on female senile drosophila melanogaster with fragmented sleep.Taking drosophilas as the model organisms,the locomotor activity was monitored using the autonomic monitoring software to explore the regulation of fragmented sleep in senile drosophilas by the treatment of SXD.As a result,it was found that the optimum concentration of SXD was 2.50％,while the desirable therapeutic duration was 4 days.In comparison with the control group,35-day-old virgin drosophilas'sleep was prolonged in the SXD group and the positive control group.The positive drug mainly affected their sleep in the daytime,while SXD impacted their sleep at night featuring the prolonged fragmented sleep.In conclusion,it was demonstrated that the freeze-dried powder of SXD effectively alleviated intermittent insomnia in the female senile drosophilas.Compared with positive drug,SXD also mitigated intermittent insomnia at night without significant changes in the sleep of the drosophilas in the daytime.Above all,SXD was beneficial in the regulation of sleep-wake rhythm in the drosophilas.

Objective To study the effects of Weibimei and its Chinese medicine portions(cortex frangulae, fennel powder, acorus tatarinowii, glycyrrhizae and asparagus) on cell cycle regulation in gastric cancer cells and growth inhibition in gastric cancer Xenografts.Methods Gastric cancer SGC-7901 cells were normally cultured and treated with Weibimei, extractum glycyrrhizae, cortex frangulae, fennel powder, acorus tatarinowii and asparagus.Then, the proliferation of SGC-7901 cells were detected by MTT assay, their effect on SGC-7901 cell cycle were measured by flow cytometry, and the expression of cell cycle related proteins were examined by Western blot.Animal models of SGC-7901 cells xenografts in nude mice were constructed to evaluate the growth inhibition effects of Weibimei and its Chinese medicine portions, and the expression of STAT3,p-STAT3, Cyclin D1, Bcl-2 and Survivin in gastric tumors were detected by immunohistochemical assays.Results Weibimei and its three kinds of Chinese medicine portions, cortex frangulae, fennel and acorus tatarinowii could obviously inhibit the proliferation of SGC-7901 cells, compared to control group, with a statistical significant difference (P<0.05).The cell cycle of SGC-7901 was arrested at G1 phase with cortex frangulae, fennel and acorus tatarinowii treatment, the expression of Cyclin A, B, D, E were decreased significantly (P<0.05).However, no significant effects was found in glycyrrhizae or asparagus group.Xenografts tumor sizes in Weibimei, cortex frangulae, fennel or acorus tatarinowi groups were much smaller than that in saline group or Triple Therapy group (three-kinds-drugs-combination for the treatment of gastric ulcer) (P<0.05).Xenografts experiments showed that the tumor growth in nude mice in Weibimei, cortex frangulae, fennel or acorus tatarinowi groups were significantly smaller than that in control group or in Triple Therapy Group (P<0.05), and phosphorylated STAT3, and STAT3 signaling targeted genes, including Bcl-2, Cyclin D1 and Survivin were all significantly down-regulated by immunostaining.Conclusion Weibimei and its Chinese medicine portions including cortex frangulae, fennel and acorus tatarinowii can could significantly inhibit the growth of SGC-7901 cells proliferation and arrested the cell cycle of G1 phase in vitro, and inhibit gastric cancer xenografts in nude mice in vivo.

OBJECTIVETo explore material bases and neurobiological mechanisms of "Shen storing will" by observing learning and memory capacities and N-methyl-D-aspartic acid (NMDA) receptor expressions in Shen deficiency constitution (SDC) rats.

METHODSTotally 40 SD rats were randomly divided into the model group, the Zuogui Pill (ZP) group, the Yougui Pill (YP) group, the blank control group (consisting of normal pregnant rats), 10 in each group. SDC young rat model (inherent deficiency and postnatal malnutrition) was prepared by the classic way of "cat scaring rat". Medication started when they were scared by cat. Rats in the ZP group and the YP group were administered by gastrogavage with ZP suspension 0.1875 g/mL and YP suspension 0.0938 g/mL respectively. Equal volume of normal saline was administered to rats in the blank control group and the model group by gastrogavage. All medication was given once per day, 5 days in a week for 2 consecutive months. Learning and memory capacities were detected by Morris water maze test. Expressions of NMDA receptor subunits NR2A and NR2B in hippocamus were detected by immunohistochemical method.

RESULTSCompared with the blank control group, the latency period, total distance in Morris water maze test were longer in the model group (P < 0.05). All the aforesaid indices all decreased in the ZP group and the YP group, with statistical difference when compared with the model group (P < 0.05). The protein expressions of NR2A and NR2B in hippocamus were lower in the model group than in the blank control group (P < 0.05). But when compared with the model group, they were obviously higher in the ZP group and the YP group (P < 0.05).

CONCLUSIONSSDC rats had degenerated learning and memory capacities and lowered NMDA receptor expressions. ZP and YP could up-regulate learning and memory capacities and NMDA receptor expressions, thereby improving deterioration of brain functions in SDC rats.
