Objective To summarize and analyze data of solid pseudopapillary tumor of pancreas (SPTP) in China,and investigate its epidemiology,clinical features,diagnosis and treatment.Methods Retrieval of Chinese Medical Current Contents and China Biology Medicine disc by the key words of solid pseudopapillary tumor of the pancreas,papillary cystic tumor of the pancreas,pancreatic papillary epithelial tumor,cystic solid tumor of pancreas and Frantz tumor were performed,and relevant literatures were included.Results A total of 1180 SPTP patients from 117 articles were involved.There were 1054 women and 126 men and the ratio of male to female was 1:8.37.The average age was 29 years old (range 9 ～83 years).Detailed clinical information was available for 1172 cases,and the main clinical manifestations included abdominal discomfort (n=526,44.88％),medical check-up (n=464,39.59％),abdominal mass (n=131,11.18％).Laboratory and imaging tests were non-specific.The tumors size was 1.3～ 30 cm with a mean value of 7.84 cm.Four handreds and seven (36.8％) cases were located in pancreatic head,96 (8.7％)were in pancreas neck and 587 (53.1％) were in the body and tail of pancreas.Eleven handreds and sixteen patients received treatment,and the resection rate was 99.2％ (n =1107).Pathological examination showed that 628(57.0％) cases were benign and 306 (27.8％) were presented as malignant behavior,mainly as infiltrative growth and invasion of the surrounding organs,vessels.Nine handreds and seventy-seven cases were followed up (ranging from 1 month to 13 years),and re-occurrence or metastasis were detected in 42 cases (4.3％) and 24 patients died.Conclusions Solid pseudopapillary tumor of pancreas is a rare pancreatic tumor with low-grade malignant potential,and part of this tumor may present as malignant behavior and it primarily affects young females.No characteristics in clinical manifestations,laboratory and imaging tests are found.Pathological examination can confirm the diagnosis.Surgical resection is the therapy of choice and the prognosis is good.

Objective To establish a rabbit model of lumbar laminectomy and bone grains replantation and provide experimental evidence for the clinical application.Methods Eighteen healthy male New Zealand rabbits were selected and randomly divided into two groups:the control group (n=6) and experimental group (n=12).The rabbits of control group were given general anesthesia, and taking the L5 spinous process as the center to perfom left L5 laminectomy, using a micro lancet forceps to slowly bite the lamina and ligamentum flavum for fenestration and exposed to an approximately 0.8 cm x 0.3 cm sized bone window and then sutured the skin.The rabbits of experimental group were exposed to an approximately 0.8 x 0.3 cm sized bone window as well, and bone fragments were cut into small grains.Then the small bone grains were embedded in medical collagen sponge, to form an arch shape, and replanted them to the site of epidural fenestration.CT scan and histological changes were observed at 4, 8 and 12 weeks after operation.Results At 8 weeks after operation, CT examination showed that in the experimental group, a thin bone plate was formed by the bone grains.At 12 weeks after operation, the bone plate became thicker and was connected with the vertebral bone, and with continuous bone trabeculae.The spinal canal and volume were not obviously changed, and no spinal cord compression was observed. The rabbits of control group showed segment lamina defects, a small scar protruding into the spinal canal, and the vertebral canal was not completely reconstructed. Conclusions The bone grains replantation can effectively promote bone reconstruction in the laminectomized rabbits, and the formed bone plate can prevent epidural scar from intruding into the spinal canal, and can reduce the postlaminectomy adhesion.

Advancements in technology have enhanced the performance of pacemakers but made the interaction between the pacemaker and the heart becoming increasingly complex, and its is difficult to interpret the paced ECGs (PGCGs). This paper introduces a brief method to interpret PECGs, which illustrate the timing intervals graphically and avoid using symbols and strings.

Objective To observe the effects of lower limb motion control training using virtual games combined with core stability training (CST) on the lower limb motor function of hemiplegic patients after stroke.Methods Sixty hemiplegic stroke patients were divided into an observation group and a control group (n =30 in each) using a random number table.The control group was given conventional treatment and CST,while the observation group received lower limb motion control training using virtual games in addition to conventional treatment and CST.All of the patients were assessed using the Fugl-Meyer lower limb assessment (FMA),the Berg balance scale (BBS),the modified Barthel index (MBI),10 metre maximum walking speed (MWS) and functional ambulation categorization (FAC)before and after 8 weeks of treatment.Results Before the intervention there was no significant difference between the two groups in any of the measurements.After the treatment,however,the average FMA,BBS,MBI,MWS and FAC in the observation group were significantly better than those before treatment and those in the control group.Conclusions Lower limb motion control training using virtual games combined with core stability training can improve effectively the lower limb motor function of hemiplegic patients after stroke.Such a combination is worth applying in clinical practice.

Objective To explore the dose-dependent and time-dependent effect of docetaxel on the expression of mammalian eukaryotic initiation factor 3 subunit A (eIF3a) in lung cancer cell line. Methods The human lung cancer cell line A549 was treated with gradient concentrations of docetaxel for different time. Real-time PCR and Western blot were used to detect mRNA and protein expression levels of eIF3a and α-tubulin, respectively. Results Docetaxel did not affect α-tubulin expression at either mRNA level or protein level. When A549 cells were treated with high concentration of docetaxel (30 μg/L), the expression level of eIF3a mRNA tended to increase in a time-dependent manner. Protein expression level of α-tubulin was not associated with eIF3a expression significantly in cells treated by docetaxel.Conclusion Docetaxel could slightly increase the expression of eIF3a mRNA, and eIF3a does not regulate the expression of α-tubulin in A549 cells treated by docetaxel.

Tie effects of L-ascorbate 2-sulfate(AAS) on fatty liver and hyperli-pemia of rat and guinea pigs induced by various treatments were studied. The results showed that AAS lowered cholesterol and total lipid levels in the serum and liver of rats fed diets supplemented with lard and cholesterol, while ascorbic acid had no obvious effect. In guinea pigs, AAS not only lowered serum lipid values and liver cholesterol, triglyceride and total lipid levels of DDT treated animals, but also prevented from decline of body weights of these animals. It also had the same effects to lower the serum and liver lipid values of those animals fed pentabarbital or high lipid diet.Remarkable increases of the lipid peroxide value of animals given high doses of AsA were observed, but no such effect occurred in those fed AAS.
