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.

Introduction:Transcatheter arterial chemoembolization (TACE) plus thermal ablation has been widely used recently in the treatment of hepatocellular carcinoma (HCC). In this study, we aimed to compare results of the combination of TACE and percutaneous thermal ablation with those of hepatectomy in patients with HCC. Methods:The clinical data of 137 HCC patients who sequentially received TACE and computed tomography (CT)-guided percutaneous thermal ablation as an initial curative treatment (combination group) and 148 matched HCC patients who received hepatectomy (surgery group) between 2004 and 2011 were collected and analyzed. After TACE, multiphase contrast-enhanced CT was performed to identify the total number of tumors as well as lipiodol deposition in the liver. Survival was calculated by using the Kaplan-Meier method and compared by using the log-rank test. The prognostic factors were assessed with multivariate Cox proportional hazards regression analysis. Results:Of all 285 patients, 225 (79.0%) had cancerous lesions≤5 cm in diameter. In preoperative contrast-enhanced CT or magnetic resonance imaging, the number of tumors was 1–4 for each patient. The 1-, 3-, and 5-year overal survival rates were 95, 74%, and 67%in the combination group and 88, 66, and 47%in the surgery group, respectively (P=0.004);the corresponding recurrence-free survival rates for the two groups were 92, 69, and 61%and 75, 58, and 44%, respectively (P=0.001). In the multivariate analysis, treatment al ocation was an independent prognostic factor for survival. Only 60 patients in the combination group had sufficient imaging data, and 135 new lesions with lipiodol deposition were diagnosed as malignancies in 22 of 60 patients, whereas 20 new lesions were found in 11 of 148 patients in the surgery group. Conclusion:The combination of TACE and CT-guided percutaneous thermal ablation for HCC improves survival of HCC patients compared with hepatectomy.

Objective To report the development of clinical symptoms in a Chinese family with autosomal dominant progressive external ophthalmoplegia(adPEO).Methods Electromyologram and muscle biopsy were performed in the proband and 4 family members with the disease.Results The proband was a 57 year-old woman,who developed bilateral ptosis after the age of 30,external ophthalmoplegia after the age of 35 years old,weakness of extremities at the age of 37 years old and bulb palsy with palmus at the age of 47 years old.In the family there were 20 male and female members from five generations.All of them complained about bilateral ptosis between 26—33 years old,external ophthalmoplegia(12/15)and weakness of all extremities(14/15)between 35—45,facial and masticatory weakness(9/9)as well as dysphagia(8/9)between 44—60,accompanied with heart lesions(4/7)after 50 years old.Some patients died due to cardiac impairment.Electromyologram showed myopathic abnormalities in the examined patients. The main myopathological changes were ragged red fibers,cytochrome c oxidase negative fibers and ragged blue fibers in succinate dehydrogenase staining.Conclusions The adPEO started from extra-ocular muscles to limbs,finally facial and bulbar muscles.Heart lesions were presented in late stage and lead to death in some members.The developing process of symptoms suggested that we should pay more attention to cardiac manifestations in this disease.

The original strain was treated with UV combining LiCl. The total carotenoid yield of the strain UL-61 was 7.62mg/L, the maximal yield of astaxanthin had reached 616.8?g/g under 25℃. 8 variables including fermentation temperature, initial pH were optimized by Plackett-Burman design and Response Surface Analysis of SAS software. The temperature, initial pH and corn steep liquor were the major factors. The optimal conditions were predictted to be 16.78℃, pH4.73 and 7.06 mg/L, respectively. Under these conditions, the theroretical maximal yield of carotenoid was 3.9407 mg/L and the practical maximal yield was about 3.9261mg/L. The carotenoid production was increased by 20.4% when Phaffia rhodozyma was cultivated under the optimal conditions as compared with the control.

Objective To analysis the clinical manifestations of mtDNA A3243G mutation in adulthood.Methods The clinical features were investigated in 36 cases (28 patients from 5 families with the mutation and 8 sporadic cases),in whom mtDNA A3243G mutation was confirmed genetically in 23 cases (15 cases from 5 mutation families and 8 sporadic cases).Cranium radiology was performed in 14 cases.Muscal biopsies were performed in l0 cases.Results Among 28 cases in the 5 family,there were 9 cases (32.1%) with stroke like episodes,17 cases (60.7%) with diabetic mellitus and 16 cases (57.1%) with deafness.Such symptoms usually combined with each other and rarely existed alone. Cardiomyopathy and renal failure were uncommon.In the 23 cases with mtDNA A3243G mutation,14 cases (61.0%) had mitochondria] myopathy,encephalopathy,lactic acidosis,and stroke-like episodes (MELAS),mostly presenting cognitive abnormalities,dysarthria or aphasia and headache,3 cases (13.0%) were asymptomatic carriers,2 cases (8.7%) had autonomic dysfunction,2 cases (8.7%) had diabetic mellitus with or without nerve deafness,1 case (4.3%) had diabetic mellitus with infertilitas and cardiomyopathy,respectively.Cranial radiological images revealed the changes more commonly in the temporal and occipital lobes and less frequently in the frontal lobes.Ragged red fibers were confirmed in 9 of 10 cases with muscle biopsies.The proportion of mutant mtDNA A3243C was not significantly different between MEALS (28.75%?13.69%) and non-MELAS (25.08%?11.54%).Conclusions mtDNA A3243G mutation mainly results in the lesions in the central nerve system,pancreatic island and acoustic nerve in adulthood.Heart and kidney are less frequently involved.Cognitive abnormalities,aphasia and headache are the major symptoms of adult MELAS.Families have with more than 1 patient with diabetic mellitus and deafness,indicating that the mutation is other than MELAS mutation.We should pay more attention to the non-MELAS symptoms in the families with mtDNA A3243G mutation.

In the present study, a new compound named 17-(6-cinnamamido-hexylamino-)-17-demethoxygeldanamycin (CDG) was obtained by introducing the cinnamic acid (CA) group into the 17-site of geldanamycin (GDM). The anti-cancer effects of CDG in vitro and in vivo were evaluated. MTT assay was used to examine the inhibitory effect of CDG on the proliferation of MCF-7, HepG2, H460 and SW1990 cells. Immunofluorescent staining flow cytometry combined with Annexin V-FITC/PI staining were used to detect apoptotic cells. Transwell assay was used to analyze the effect of CDG on cell invasion and migration ability. Western blotting was used to detect the expression levels of RAF-1, EGFR, AKT, CDK4 and HER-2 of MCF-7, HepG2 and H460 cells. The toxicities of CDG and GDM were evaluated in mice. Using the subcutaneously transplanted MCF-7 xenograft in nude mice, inhibitory effect was evaluated in vivo. The results showed that CDG inhibited the proliferation of cancer cells (IC50: 13.6-67.4 microg.mL-1). After exposure to CDG for 48 h, most cells presented typical morphologic changes of apoptosis such as chromatin condensation or shrunken nucleus. The rates of apoptosis of MCF-7, HepG2, H460 and SW1990 cells incubated with 10 microg.mL-1 CDG were 23.16%, 27.55%, 22.21%, 20.47%, respectively. A dose-dependent reduction of migration of four cell lines was found after exposure to CDG. The decreased levels of RAF-1, EGFR, AKT, CDK4 and HER-2 showed that CDG possessed HSP90 inhibitory effect. The result of animal toxicity test on the mice suggested that CDG had lower toxicity than GDM. Meanwhile, CDG inhibited the growth of MCF-7 xenografts of athymic mice.
