Objective To explore the clinical effect of one new type of short section pedicle of vertebral arch nail system(internal fixation system by nail-stick) on patients with thoracolumbar fracture.Methods 68 patients with thoracolumbar fracture were selected.Internal fixation system by nail-stick was used on the patients with thoracolumbar fracture,the clinical effect was observed.Results After following up for six to eighteen months,the vertebral height was measured by X-ray.The anterior edge height of the vertebral was 47% before operation and 94% after operation,the posterior edge height of the vertebral was 76% before operation and 97% after operation,there was significant difference between preoperation and post operation(P<0.01).All the cases with AF intemal fixation system had better clinical effect,18 cases had satisfactory effect.Except that the neurological deficits of 4 cases had not been improved,those of the other cases all had been impreved at some degree.Conclusion Thoracolumbar fracture should be treated early,AF imtermal fixation system has significant effect on the thoracolumbar fracture,the skilled performance is important during the operation,and contraindications of internal fixation system by nail-stick should be noticed.

Objective To evaluate the accuracy of bispectral index (BIS) in predicting outcomes in patients with cerebral hemorrhage.Methods A total of 103 patients of either sex with acute cerebral hemorrhage,aged 18-77 yr,with body mass index of 17-29 kg/m2,of American Society of Anesthesiologists physical status Ⅱ-Ⅳ,undergoing craniotomy for evacuation of hematoma,were enrolled in this prospective study.BIS electrodes were adhered to the forehead of patients,and the BIS value was continuously recorded for 20 min.The maximum BIS value (BISmax) and minimum BIS value (BISmin) were recorded,and the mean BIS value (BISmean) was calculated.The patients were divided into 2 groups according to Glasgow Outcome Scale (GOS) scores assessed at 6 months after surgery:good outcome group (GOS score≥ 3) and poor outcome group (GOS score 1 or 2).The receiver operating characteristic curve of BIS in predicting outcomes was plotted,and the area under the curve (AUC) and 95％ confidential interval (CI) were calculated.The best cut point and sensitivity and specificity were calculated according to the BIS value when Youden index reached the maximal value.Results The AUC (95％ CI) for BISmax in predicting outcomes was 0.903 (0.830-0.976),the best cut point 79,the sensitivity 84％,the specificity 86％,and Youden index 0.695.The AUC (95％ CI) tor BISmin in predicting outcomes was 0.841 (0.760-0.921),the best cut point 43,the sensitivity 86％,the specificity 71％,and Youden index 0.577.The AUC (95％ CI) for BISmean in predicting outcomes w() 0.883 (0.800-0.958),the best cut point 60,the sensitivity 90％,the specificity 76％,and Youden index 0 562.Conclusion BIS can accurately predict outcomes in patients with acute cerebral hemoorrhage,and BISmax provides the highest accuracy.

Objective To investigate the effect of puerarin and compound salvia injection on P2selectin change in patients with traumatic cerebral infarction(TCI)so as to understand the difference of their curative effect. Methods Twenty patients with TCI were randomly divided into four groups,ie,conventional treatment group,puerarin group,compound salvia injection group and combined treatment group to observe the improvement of the symptoms(Glasgow Outcome Scale,GOS)and change of plasma P2 selecfin after treatment.Results The symptoms(GOS score)and level of plasma P2 selectin in the puerarin group,the compound salvia injection group and the combined treatment group were superior to those of the conventional treatment group(P<0.05).The TCI patients had obviously higher level of plasma P2 Selectin than the healthy persons before treatment.The level of plasma P2 selectin was decreased after treatment,with better curative effect in three other groups compared with the conventional treatment group. Conclusions There is positive synergistic interaction between puerarin and compound salvia injection.Both puerarin and compound salvia injection Can decrease the level of plasma P2 Selectin to reduce the blood viscosity,inhibit the platelet activation,reduce the cerebral vasospasm and inhibit the thrombosis,as contributes to the recovery of the TCI patients.

Histone deacetylase (HDAC1) has a high expression in many cancer cells and curcumin can inhibit the growth of cancer cells. This paper was designed to investigate the expression of HDAC1 of Raji cells and the effect of curcumin on their proliferation and apoptosis. Raji cells were treated with 3.125-50 micromol/L curcumin for 8-48 h and the growth inhibition rates of Raji cells were measured by MTT. The expression of HDAC1 on Raji cells were examined by mRNA, Western blot at 24 h various concertrations (1.6-50 micromol/L). Curcumin could selectively inhibit the proliferation of Raji cells in a dose- and time-dependent manner, with the inhibition rate being 52.47 %-82.18 % (P<0.01). The up-regulation of HDAC1 expression was observed within 24 h after the treatment with curcumin as shown by RT-PCR and Western blot. With the increase of concentration, the expression was down-regulated in a dose- dependent manner. It is concluded that the expression of HDAC1 plays an important role in the proliferation and apoptosis of Raji cells and curcumin can inhibit the growth of Raji cells at various concentrations and promote the apoptosis of Raji cells.

Berberine (BBR) is a type of alkaloids isolated from Coptidis Rhizoma and Phellodendri Chinensis Cortex and has been used to treat bacterial gastroenteritis, diarrhea and other digestive diseases for more than 1 000 years. According to recent studies, berberine has been found to have multiple pharmacological activities, including lowering blood glucose and lipid, anti-inflammation, antioxidation, relieving type 2 diabetic nephropathy (DN), diabetic cardiovascular disease, diabetic peripheral neuropathy ( DPN) and other complications. In this article, the authors summarized the literature reports about the effects of BBR in lowering blood glucose and preventing and treating the above type 2 diabetes and its complications, in order to provide reference to further studies and promotion of BBR's application.

Objective To compare the therapeutic effect of routine dose of calcitriol and large dose impulsion therapy on hemodialysis patients with secondary hyperparathyroidism(SHPT). Methods 48 uremic hemodialysis patients were divided into group A(routine group, n = 22) and group B(control group, n = 21 ). In group A,22 pa-tients were administered with calcitriol for 6 months at the dosage of 0.25～0.5μg/d,adding calcium agents simul-taneously;the patients in group B were not given calcitriol for economic reason. In group C,21 patients were given calcitriol twice a week at the dosage of 2μg/time after hemodialysis for 3 months. Results Comparing to group B,serum PTH,AKP in group A had no significant difference,but serum hypocalcium and hyperphasphate were partly corrected,symptoms of bone pain, muscular convulsion and akin pruriter were improved. Comparing to group A,serum hypocalcium and hyperphasphate in group C were corrected, serum PTH, AKP were significantly decreased( t=2.031,P<0.05;t =3.317,P<0.001),and no hypercalcium oecurred. Conelosion Routine dose of calcitriol can not control uremic-SHirr,while impulsion therapy with lower dose oral calcitriol is effective and safe.

At present, the level of diagnosis and treatment of early gastrointestinal cancer has a larger gap between China and developed countries. In recent years, the advent of new endoscopic imaging techniques has improved the detection rate of early gastrointestinal cancer. Along with this, endoscopic submucosal dissection(ESD) enables radical resection for early cancer. In this article, we discuss how to improve the level of endoscopic diagnosis and treatment of early gastrointestinal cancer.
