Objective To investigate the therapeutic effect and analgesic mechanism of percutaneous vertebral angioplasty in the treatment of painful osteoporotic thoracolumbar vertebral compression fracture.Methods80 cases of patients with painful osteoporotic thoracolumbar vertebral compression fracture in Shaoxing second hospital from May 2014 to May 2016 were selected, they were randomly divided into percutaneous vertebroplasty group (40 cases) and conservative treatment group (40 cases) two groups, the clinical efficacy, VAS scores and ODI scores of the two groups were statistically analyzed.ResultsThe total treatment effective rate of the percutaneous vertebroplasty group 95% (38/40) was significantly higher than the conservative treatment group (30/40) (P<0.05);The VAS scores and ODI scores of the two groups after treatment were significantly lower than before treatment (P<0.05);The differences of VAS scores and ODI scores before treatment between the two groups were not significant.The VAS score and ODI score after treatment of the percutaneous vertebroplasty group were significantly lower than the conservative treatment group (P<0.05).ConclusionThe therapeutic effect of percutaneous vertebral angioplasty in the treatment of painful osteoporotic thoracolumbar vertebral compression fractures is more significant than conservative treatment, it has better analgesic effect, so is worthy of promotion in the clinical.

Objective To investigate the role of bone marrow-derived cells (EMC) plays in choroidal neovascularization (CNV).Methods Green fluorescent protein (C-FP) chimeric mice were built by transplanting BMC from GFP transgenic mice to adult wild type C57BL/6J mice.Retinal laser photocoagulation was used to induce CNV in the chimeric mice (treated group) and adult wild type mice (control group).Four weeks later,choroidal flatmount was prepared to detect GFP positive BMC expression in the CNV lesions,and immunofluorescence stain was used to determine the expression of vascular endothelia growth factor (VEGF) and basic fibroblast cell growth factor (bFGF).Results Twenty-nine days after photocoagulation lots of GFP positive BMC presented in the CNV area,which accounted approximate 16.22% of the total CNV area.Some BMC in the CNV area expressed VEGF and bFGF.Conclusions BMC may play an important role in CNV by forming new vessles and secreting angiogenic factors.

Objective　To evaluate the clinical efficiency of diode laser transscleral cyclophotocoagulation(TSCPC) for the treatment of refractory glaucoma.Methods　TSCPC were performed in 23 eyes of 23 patients with medically and surgically uncontrolled glaucoma. The laser was operated with a power of 2～3W,duration of 1.5～2s and laser spots(18) were evenly placed 270 around the limbus except temporal. Followed for 3～24 months (average:11 months) . Results　The mean intraocular pressure before and after treatment in 23 eyes were 6.10kPa±2.34kPa and 2.55kPa±1.22kPa respectively,which was statistically significant (P<0.01). IOP below 2.80kPa was obtained in 20 eyes (86.9%). At the time of last visit,the post-operative visual acuity was partly improved besides NLP.Conclusion　Diode laser transscleral cyclophotocoagulation is effective in treating refractory glaucoma. Its advantages are low ratio of ocular hypotension,no atrophy of eyeball,no pain, acceptability,reoperation and therapeuty in clinic and so on.

Objective To evaluation of curative effect of Yiqi-Wenshen decoction combined with salmon calcitonin subcutaneous injection for the patients with postoperative bone atrophy after calcaneal fracture.Methods According to the inclusion criteria, 120 patients with calcaneal fracture were randomly divided into 2 groups, 60 in each group. The control group received the subcutaneous injection of salmon calcitonin, and the combined group received the control group treatment plus Yiqi-Wenshen decoction. Both groups were treated for 6 weeks. The X-ray was used to detecte the local bone density of limbs, and the foot function scores of ankle function and the changes of clinical symptoms and signs before and after treatment were observed.Results After treatment, joint pain (2.8 ± 1.1vs. 3.6 ± 1.1,t=4.129), tenderness (1.0 ± 0.5vs. 1.4 ± 0.7,t=3.297), the color change of (1.5 ± 0.8vs. 2.0 ± 0.6,t=3.117) score in the combined group were significantly lower than those in the control group (P<0.05). The degree of swelling (112.5 ± 11.8 cm3vs. 122.5 ± 13.6 cm3,t=3.816) in the combined group was significantly lower than that in control group (P<0.05). The bone mineral density (0.762 ± 0.020 g/cm2vs. 0.722 ± 0.023 g/cm2,t=3.803,P<0.05) in the combined group was significantly higher than that in the control group. The effect rate of the combined group was 90% (54/60), and the control group was 70%. There was significant difference between 2 groups (χ2=7.500,P=0.006). The effect rate of ankle joint function of the combined group was 83.3% (50/60), and the control group was 70% (42/60). There was significant difference between 2 groups (χ2=4.444,P=0.035).Conclusions The Yiqi-Wenshen decoction combined with subcutaneous injection of salmon calcitonin could relieve the pain, swelling and other symptoms of the patients with bone atrophy after calcaneal fractures, and could benefit the recovery of ankle joint function.

Mitochondrial DNA mutations are one of the most important causes of sensorineural hearing loss. A1555G and C1494T mutations of mitochondrial 12S rRNA gene are the molecular basis for aminoglycoside hyper- sensitivity and can lead to aminoglycoside-induced hearing loss. Primary mutations in tRNA such as tRNA(Ser(UCN))7472insC are associated with syndromic hearing loss. While other mutations such as tRNA"(Se(UCN) )G7444A were considered synergy with the primary RNA mutations, modulating the phenotypic manifestation. This review de- scribes a detailed summary of hearing loss associated with mtDNA mutations and/or aminoglycoside antibiotics, and provides the possible molecular mechanisms in deafness expression.

Objective To assess the contribution of CT perfusion in the quantitative diagnosis of meningiomas Methods The CT perfusion imaging was performed in 13 patients (including 2 recurrent meningiomas) by using Somatom Plus 4 helical CT The color map of relative cerebral blood volume (rCBV), relative cerebral blood flow (rCBF), and mean transit time (MTT) was obtained by perfusion software, and rCBF, rCBV, and MTT were calculated in different areas Then the perfusion parameters and its mean ratios between tumor and contralateral normal brain tissue (CNBT) in each group of different pathologic types of meningiomas were compared using an unpaired or a paired Student t test Results The rCBV, rCBF, and MTT of meningiomas were significantly higher than those of CNBT [rCBV:(16 125?12 135) ml/100 g vs (2 158?1 345) ml/100 g, P 0 05) The characteristic time density curve (TDC) with high peaks was seen in 5 cases The rCBV and rCBF of 4 cases with peritumor brain edema were significantly lower than those of CNBT Conclusion CT perfusion imaging can not only provide quantitative information of meningiomas blood flow and show characteristic dynamic TDC, but also is useful in assessing pathology of tumor and demonstrating lower perfusion in peritumor brain edema and diagnosis of recurrent meningiomas

Objective To evaluate skin barrier function in children with atopic dermatitis (AD) as well as healthy children from two communities in Shanghai and to assess the relationship between skin barrier function and AD severity.Methods Totally,169 children with AD and 142 healthy children aged 3-12 years were recruited from two communities (Changning Xining community and Jiading Juyuan community) in Shanghai,China.Transepidermal water loss (TEWL) and stratum corneum hydration were measured in normal appearing nonlesional skin at four body sites (dorsal and volar forearm,cheek and anterior shin) of the patients,as well as in normal skin at the same sites of the controls.AD severity was evaluated by using the severity scoring of atopic dermatitis (SCORAD) index.Results Compared with the healthy children,the patients with AD showed higher TEWL value at all of the four body sites (all P ＜ 0.05),but lower water content in stratum corneum at dorsal forearm and anterior shin (both P ＜ 0.05).In patients with AD,the SCORAD index was positively correlated with mean TEWL value,but negatively correlated with the mean water content in stratum corneum.Conclusion Skin barrier function may serve as an index for evaluating the severity of AD.
