Objective To evaluate the effect of transverse position and numbers on the stability of the spinal pedicle screw fixation during the pedicle cortex perforation. Methods The vertebral compression fracture was performed in the L1 vertebral body using the Chiba's method from 60 fresh thoracic and lumbar vertebrae samples of sheep(T13-L3),which were randomly divided into 6 groups(A,B,C,D,E,and F)using a lottery method. Bilateral pedicles of vertebral arch of T14 and L2 were inserted pedicle screws,connecting titanium rods to fix T14-L2 segments. Then the samples of groups B,C,D,E,and F were removed a quarter of right side of lateral T14 thoracic pedicle cortical,which were considered the pedicle cortex perforation model. Finally,each group was fixed on different numbers of crosslinks:group A(0 crosslink,Intact),group B(0 crosslink,NCL),group C(1 crosslink,1/2 of the rods,MCL),group D(1 crosslink,1/3 of the rods close to T14,PCL),group E(1 crosslink,2/3 of the rods away from T14,DCL)and group F(2 crosslinks,1/3 and 2/3 of the rods respectively,TCL). After all samples were subject to 10 000 times of fatigue test with biomechanics test machines,the axial compressive stiffness,range of the motion(ROM)of the 6 directions(flexion,extension,lateral bending,and axial rotation),and the maximum pullout of the screws of the T14 pedicle cortex perforation were measured and compared among these 6 groups. Results The axial compressive stiffness in groups A,C,D,E,and F was significantly higher than that in group B(all P<0.05),and group A was significantly higher than group F(P<0.05) . The maximum pullout in groups A,C,D,E,and F were significantly higher than that in group B(all P<0.05),and group A was significantly higher than group F and groups C,D,and E were significantly lower than group F(all P<0.05). ROM of flexion,extension,lateral bending,and axial rotation in groups A,B,C,D,E,and F were significantly lower than that in group B(P=0.000),and ROM of left and right axial rotation in groups C,D,and E were significantly higher than in that group F(P=0.000). Conclusions During the pedicle cortex perforation,adding of one crosslink can improve the stability of the pedicle cortex perforation,and adding of two crosslinks can approximately achieve the same stability as the pedicle screw fixation with no pedicle cortex perforation. The location of the crosslink has no obvious effect on the short segment of spinal fixation.

Objective:To investigate the clinical therapeutic effect of low-dose chemotherapy in advanced gastrointestinal cancer patients with weak physical condition, and to evaluate the related factors affecting the prognosis.Methods:The clinical data of 118 advanced gastrointestinal cancer patients with weak physical condition who were admitted to Xiamen Branch, Zhongshan Hospital, Fudan University from March 2018 to May 2019 were retrospectively analyzed. Kaplan-Meier method was used to make survival analysis in patients stratified by different factors, and log-rank was used to test. Multiple factor analysis of prognosis was performed by using Cox regression model. The association of clinicopathological factors with the prognosis was evaluated.Results:Among 118 patients, 16 (13.6%) cases were esophageal cancer, 41 (34.7%) cases were gastric cancer, 48 (40.7%) cases were colorectal cancer, 13 (11.0%) cases were pancreatic cancer. The overall survival (OS) rates of 6 months and 1-year were 44.1% and 10.2%, respectively. Survival analysis showed that patients with hemoglobin ≥100 g/L, serum albumin > 40 g/L and normal gastrointestinal function had better OS (all P < 0.05), while patients with physical status score of 3 scores and pain had worse OS (all P < 0.05). Cox multivariate analysis showed that after adjusting age and gender, hemoglobin level ( HR = 0.314, 95% CI 0.241-0.977, P = 0.001), pain ( HR = 2.016, 95% CI 1.697-7.038, P = 0.008) and gastrointestinal function ( HR = 1.751, 95% CI 1.607-6.080, P = 0.036) were independent influencing factors of OS in advanced gastrointestinal cancer patients with weak physical condition after receiving low-dose chemotherapy. Conclusions:Low-dose chemotherapy can still benefit advanced gastrointestinal cancer patients with weak physical condition. Hemoglobin level, pain and gastrointestinal function are independent prognostic factors for these patients.

OBJECTIVE: To compare the hepatotoxicity which induced by rifamycin sodium and isoniazid by alone or combination in mice. METHODS: Forty mice were divided randomly into 4 groups: the sodium chloride group, the rifamycin sodium group, the isoniazid group and the drug - combination group. The drugs were administered to mice by i. p. or i. g. once daily for 8 days. Each mouse was killed by ophthalmectomy. The blood was collected and the liver was excised immediately. The activity of serum ALT and AST was measured and the liver index in mice was calculated. Light microscope was used to observe the histopathological changes of the hepatic cells. RESULTS: The liver index and the activity of serum ALT and AST increased in all groups expect the sodium chloride group( P

The present study aims to isolate neural stem cells from neonatal rat hippocampus and induce them to differentiate into cholinergic neurons. A multipotent cell line derived from the hippocampi of neonatal rats which had the ability to form clones was incubated in serum-free DMEM/F12 medium added with 20ng/ml basic fibroblast growth factor (bFGF) and B27. After differentiation of the neural stem cells, immunocytochemistry was used to detect nestin, the antigen of the cell clone, and β-tubulin (Tuj 1 ), glial fibrillary acidic protein (GFAP) and galactocerebroside (Galc), the markers specific for neurons, astrocytes and oligodendrocytes, respectively. Embryonic chick skeletal muscle extract was used to induce the differentiation of the neural stem cells into cholinergic neurons. The results showed that the cell line isolated from the hippocampi of neonatal rats expressed nestin and had the potential to form clones and differentiate into neurons, astrocytes and oligodendrocytes. Embryonic chick skeletal muscle extract can induce 9.6% of the isolated cell line to differentiate into cholinergic neurons compared with 3.9% in controls. These findings suggested that the cell line, which expressed nestin antigen, was a multipotent cell line capable of self-renewing, and was believed to contain stem cells of the CNS. These neural stem cells can be induced to differentiate into cholinergic neurons by using embryonic chick skeletal muscle extract.
