BACKGROUND:Because it can reduce the risk of postoperative bone cement leakage, percutaneous kyphoplasty is increasingly used for treatment of severe osteoporotic thoracolumbar vertebral compression fractures. Studies have found that injection of mixed bone cement with high viscosity can significantly reduce the leakage of bone cement. OBJECTIVE:To compare the therapeutic efficacy of percutaneous vertebroplasty with high viscosity bone cement and percutaneous kyphoplasty with standard viscosity bone cement in the treatment of severe osteoporotic thoracolumbar vertebral compression fractures. METHODS:Eighty patients with severe osteoporotic thoracolumbar vertebral compression fractures were enroled and randomized into vertebroplasty group and kyphoplasty group, 40 patients in each group. Visual analog scale score and Oswestry disability index score were compared between groups before and after treatment. Incidence rate of bone cement leakage and other complications were also compared between two groups after treatment. RESULTS AND CONCLUSION:No significant difference was found between the visual analog scale scores of two groups after treatment (P> 0.05). Patients in the two groups al presented with good recovery of spinal function after treatment, and there was no difference in the Oswestry disability index scores between groups at 3 months after treatment (P> 0.05). The incidence rate of bone cement leakage was 45% in the vertebroplasty group and 30% in the kyphoplasty group, with a significant difference (P < 0.05). But the patients in both groups showed no obvious clinical symptoms and underwent no treatment. After treatment, al patients had no pulmonary embolism, bone cement toxicity, spinal cord and nerve root injury. These findings show that there is no significant difference between percutaneous vertebroplasty and kyphoplasty with high-viscosity bone cement in the folowing aspects: pain improvement, recovery of the spinal function, incidence rate of bone cement leakage and clinical efficacy.

Objective: To investigate the significance of laminin(LN) and laminin receptor(LN-R) in the proceeding and prognosis of hydatidiform mole.Methods: Immunohistochemical SP staining was used to detect the expression of LN and LN-R in 41 hydatidiform mole cases(13 cases were learned to have turned malignant by following up).20 cases of normal early gestational chorion were detected as control.Results: The strong positive rates of LN and LN-R in normal chorion,hydatidiform mole un-malignant group and malignant group were respectively 90.0%(18/20),71.4%(20/28),38.5%(5/13),and 70.0%(14/20),71.4%(20/28),84.6%(11/13).The strong expression of LN had a significant difference between malignant group and the other 2 groups(P

Objective To explore the etiology of abdominia incision hernia and treatments of giant incisional hernia of abdominal wall. Methods 14 cases with AGIH treated in our hospital from Oct 2003 to May 2008 were analyzed retrospectively. Results The etiology of abdominia incision hernia were very important,and abdominal longitudinal incision was performed, 10 cases ＞ 67y among 14 cases with incision hernia were 71.42%. Infection of incision and essential conditions( diabetes, chronic cough ,hypoalbum inemia)were also easily induced of incisional hernia. All of them chose the marlex patch. The cases were all cured and no serious postoperative complications. None of cases recurred during a follow up of 3 to 56 months. Conclusion The etiology of AGIH related with longitudinal incision,old ( ＞ 60y)and essential conditions. AGIH were repained with polypropylene mesh. Essential conditions should be treated before operation and abdominal wall should be trained comfortablely. Repairing abdominal incision hernial with artifical patch was a safe and simple operation with minimal postoperation pain.

The constitutional medical thoughts in Inner Canon of Huangdi is the foundation for TCM constitution theory, it discusses the influence of constitution on disease in detail. Constitution factors determine the disease onset or not; Constitution factors determine the tendency and character of disease. Constitution factors effect the changes of pathogenesis, the character of syndrome, the therapeutic principle and methods; Constitution factors effect the turnover and prognosis. Constitution therapies are profit to correct the partial body, preventing the development of disease and heal the disease.

Objective To investigate the application value of intraoperative ultrasound (IOUS) in living donor liver transplantation(LDLT). Methods In LDLT, IOUS techniques (gray scale ultrasound and color Doppler flow imaging) were adopted in 26 donors and recipients for parenchymal and vascular examinations. The abnormal sonograms were observed, and the anatomic findings of hepatic veins were recorded. All the reanastomosed blood vessels were examined by gray scale ultrasound and color Doppler flow imaging before the operations were completed. Results A hepatic parenchymatous tumor was revealed by IOUS in one donor. Besides, middle hepatic veins in 13 donors and secondary hepatic veins with diameter﹥0.5 cm in 5 donors were confirmed by IOUS. Furthermore, one operation procedure was changed and one hepatic artery stenosis was established according to IOUS findings. Conclusion IOUS is a very useful means in evaluation of parenchymal and vascular conditions of donors and recipients in LDLT, which helps to select the best cross section and provides evidence for the change of surgical procedures.

Objective To screen and optimize the preparation process of Radix Ginseng Capsules.This paper compares the reflux extraction and effects of infiltration percolation extraction to the renshenshouwu capsules.Methods Based on the Orthogonal test,the content of ginsenosides Rg1 and Stilbene glycoside were measured by HPLC.The transferring rates of ginsenosides Rg1 and Stilbene glycoside (1:1 )were regarded as the index to evaluate extracting conditions ,such as the ethanol concentration (%),consumption of alcohol (times),extraction time and extraction times (times). Results The optimum extract conditions of ginsenosides Rg1 and Stilbene glycoside are:with 8 times volume of 50%concentration ethanol as the extract liquid,to refluxing extract 1 times,1.5 h every time.Conclusion The preparation method is simple,practical,high stability and provides the basis for industrial production.

ObjectiveTo analyse the changes of electrolytes and electrolyte disturbances within 72 h in asphyxia neonates. MethodsTwenty-three severe-asphyxia neonates (asphyxia group) and 27 mildasphyxia neonates(control group) were selected.Venous blood samples of 2 ml were drawn at 0-24 h, 25-48h and 49-72 h respectively. The changes of electrolytes(such as plasma sodium, potassium, chlorine,calcium and magnesium) and the incidence of hyponatremia,hypokalemia,hypocalcaemia and hypomagnesemia were compared between two groups. ResultsThe levels of plasma sodium, calcium at 0-24 h, 25-48 h and 49-72 h in asphyxia group were lower than those in control group (P ＜ 0.05). The levels of plasma magnesium at 25-48 h and 49-72 h in asphyxia group were lower than those in control group (P ＜ 0.05 ), but there was no significant difference at 0-24 h (P ＞ 0.05 ). The levels of plasma potassium at 49-72 h in asphyxia group was lower than that in control group(P＜ 0.05). There were no obvious changes in plasma chlorine, phosphorus in two groups (P＞0.05). Hyponatremia, hypokalemia, hypocalcaemia was happened within 72 h in asphyxia neonates especially at 25-48 h, but hypomagnesemia was more at 25-48 h and 49-72 h. ConclusionElectrolyte disturbances can appear not only in 24 h, but also in different periods after asphyxia, therefore, it is necessary to maintain homeostasis by taking corresponding measures according to the changes of blood gas and the changes of electrolytes.

Breast cancer stem cells (BCSCs) play an important role in radiation and chemotherapy resistance.Different cancer subtypes mean different BCSCs.Inhibitors for BCSCs are gradually explored in clinical trials.Circulating tumor cells (CTCs) are crucial process to tumor metastasis.CTCs seem to be associated with stem cell phenotype.Therefore,further research for BCSCs will enable us to achieve improvement of their clinical application.
