OBJECTIVETo explore the therapeutic efficacy of unilateral multiple channels approach in percutaneous vertebroplasty (PVP) for osteoporotic vertebral fractures.

METHODSA retrospective review (from March 2003 to October 2012) was conducted on 685 consecutive patients, a total of 885 vertebrae were involved. Eighty-two cases (99 vertebrae) with bone cement leakage when less than 0.3 ml bone cement was injected to fill the fracture were given PVP procedure by unilateral multiple channels approach. 38 cases were male (45 vertebrae) and 44 cases were female (54 vertebrae). The average age was 75.4 years old (from 69 to 92). The operation time, amount of injected bone cement and complications were recorded. Rate of excellent and good outcomes was studied by measuring the cement distribution on the X-ray film. The visual analogue scale (VAS) score and Oswestry disability index (ODI) system were used to evaluate the pain relief and improvement of daily activity function respectively at preoperation and 1 hour, 1 month, 3 months and 6 months after operation.

RESULTSAll these ninety-nine vertebrae were treated in 82 cases with PVP of unilateral multiple channels approach. The average operation time was 33 minutes. The rate of excellent and good outcomes of cement distribution was 98.8%. The VAS score was (8.40 +/- 0.73) before surgery,and (2.50 +/- 0.43), (2.00 +/- 0.33), (1.80 +/- 0.28), (2.10 +/- 0.17) at 1 hour, 1 month,3 months and 6 months respectively after operation. ODI was (40.94 +/- 2.72) before surgery, (9.64 +/- 2.60) at 1 month after surgery, (8.52 +/- 2.30) at 3 months after surgery and (7.77 +/- 2.15) at the final follow-up. The differences of the VAS and ODI between pre-operation and post-operation had statistical significance (P<0.01). No spine or nerve injuries occurred intraoperatively.

CONCLUSIONThe unilateral multiple channels approach in percutaneous vertebroplasty can obviously relieve the pain and effectively improve the functional activity, provide a satisfied cement distribution in vertebral body with cement leakage after a small amount infusion.

Four specific salt-tolerant fungi for dissolving phosphate rock (FM) w ere isolated from the coastal saline soils. It was found that the biomass and a b ility to release phosphate from the materials decreased with increasing of the N aCl content. During pH7.0～8.5, the biomass and ability of to release phospho rus from the materials of FM1 decreased sharply with pH rising, but the FM2 and FM4 decreased not considerably, optimal pH for FM3 was at pH8.5. At pH9.0, the bi oma ss and ability of to release phosphorus from the materials decreased quickly. F M2 was stable at alkaline and high salt content condition.

Objective To investigate etiology and clinical features of acute pancreatitis (AP) in young patients. Methods In total, 423 patients with AP admitted to Renmin Hospital of Wuhan University, Wuhan, Hubei province during January 2006 to December 2009 were retrospectively analyzed, 55 cases aged 34 years or less as young group and another 55 cases aged more than 34 years as middle- and elderly-age group. Their etiology, clinical features and illness scores based on some standard criteria were assessed. Results Proportion of varied etiologies of AP in young group was different from that in middle- and elderly-age one (x2 = 17. 107, P = 0. 009) , mainly as biliary and idiopathic pancreatitis in young group and as biliary and alcoholic pancreatitis in middle- and elderly-age one. Incidence of diet-related and idiopathic pancreatitis were higher in young group than that in middle- and elderly-age one ( x2 =4. 853, P = 0. 028 and x2=4. 274, P = 0. 039 ). Scores of the acute physiology and chronic health evaluation II ( APACHE II ) , Ranson criteria and the bedside index for severity in acute pancreatitis ( BISAP) were all lower in young group than those in middle- and elderly-age one (t = 5. 381 , P = 0. 000; t = 4. 388 , P = 0. 000 and t=3. 083, P = 0. 003 ) . There was no statistically significant difference in scores of computed tomography severity index ( CTSI) between young group and middle- and elderly-age one (t = ±0. 750, P > 0. 05 ) . Recurrence rate of AP was lower in young group than that in middle- and elderly-age one ( x2 =4. 251, P = 0. 039). Cholecystitis was more complicated in young group, pregnancy was more complicated in young group (x2 =4. 151 , P =0. 042) , and elevated blood glucose was more complicated in middle- and elderly-age one (x2 = 13. 285 , P = 0. 000 ) . Conclusions Etiology of AP varies in young patients with more dietary factors, occurrence of systemic complications and risks for death are lower in young group than those in middle- and elderly-age one, and there was no statistically significant difference in local complications and severity of illness between the two groups.

The prevalence of obesity is increasing. It is associated with conditions such as type 2 diabetes mellitus, hypertension, dyslipidaemia and non-alcoholic fatty liver disease and together with its co-morbidities, obesity has become a fast-growing public health concern and health burden. However, weight loss has been shown to reduce the development and improve these conditions. This paper looks at the epidemiology, obesity-related comorbidities, in particular pre-diabetes, and the various strategies that can be implemented to prevent and treat this looming problem.

Aim To discuss the pathway of resveratrol for anti-acute myeloblastic leukemia.Methods Human acute myeloblastic leukemia cell Kasumi-1 was applied in this study.After different doses of Res treatment for different time, methyl thiazolyl tetrazolium(MTT)colorimetry was used to detect the cell proliferation.Furthermore, apoptosis and cell cycle were detected by flow cytometry.Western blot and reverse transcription polymerase chain reaction(RT-PCR)were used to detect the expression levels of Bcl-2 and Bax for mRNA and protein.The activity of signal transducers and activators of transcription 3(STAT3)was detected by immunoblotting and Luciferase reporter gene assay.On the other hand, leukemia-bearing mice models were made to investigate the live situation, survival time and the activation of STAT3 by Western blot and immunohistochemical method.Results Resveratrol could suppress the proliferation of Kasumi-1, and induce cell cycle arrest and apoptosis.At the same time, the ratios of Bcl-2/Bax and phosphor-signal transducers and activators of transcription 3(p-STAT3)were decreased significantly.In vivo, resveratrol could prolong the life span of Kasumi-1-bearing mice and attenuate the activity of STAT3 in a dose-dependent manner.Conclusions Resveratrol is a natural occurring chemotherapeutic agent present in Chinese Herbals.The regulatory effect on signaling pathways involved in STAT3 by resveratrol may be associated with its anti-leukemia effect.

Objective To analyze the clinical features in patients with primary cardiac tumors and surgical treatment of primary cardiac tumors.Methods A retrospective analysis of primary cardiac tumors patients from June 2002 to September 2012 was performed.79 patients were confirmed using cardiac echocardiography.Primary cardiac tumors were excised using general anesthesia during cardiopulmonary bypass.Results Only 5 patients relapsed after the follow-up for 6 months to 5 years.No tumor recurrence and distant metastases were found in the other patients.Conclusion Left atrial myxoma should be removed by surgical resection as soon as possible once there is a clear diagnosis.The surgical effect of left atrial myxoma is good but it may relapse.The malignant cardiac tumors progress rapidly and should be removed by early surgery combined with comprehensive treatment to improve the prognosis.
