Objective To evaluate the sunscreen application and the level of photoprotective knowledge in both dermatologists and photosensitive patients. Methods The style, sites and amount of the sunscreen applied were examined by 0. 05 % dipyridamole cream in 39 dermatologists and 41 photosensitive patients with Wood's light. The participants were asked to fill in a questionnaire about the photoprotective knowledge. Results Frequent mistakes made by participants in this study were as follow: (1) using an inadequate amount of sunscreen; (2) putting sunscreen in the palm of the hand and rubbing the hands together before application; (3) lacking a systematic approach to sunscreen application. The median quantity of individual sites ranged from 0. 5 mg/cm2 to 1 mg/cm2 except for the forehead of the female dermatologist that had a median thickness of 1. 5 mg/cm2. The questionnaire survey showed that dermatologists also had less knowledge on sun protection even though better than photosensitive patients. Conclusions Dermatologists and photosensitive patients always fail to apply sunscreen in some prominently exposed sites and to paint the average thickness of sunscreen used far less than that of experimentally measured dose (2 mg/cm2). Continuing education and training about pho-toprotection for dermatologists should be carried out to provide better education for the patients on sun protection.

Objective To explore the effect of Lee Silverman voice treatment on the speech and life quality of Parkinson's disease patients.Methods A total of 98 patients with Parkinson's disease anddifferent degrees of speech disorder (Hoehn-Yahr clinical stages 1 to 3) were randomly divided into an intervention group and a control group,each of 49,according to a random number table.The control group was given routine speech therapy covering tongue and lip movement,rhythm,sound,volume,speed and respiratory control.The intervention group was provided with 12 weeks of Lee Silverman voice treatment aimed at abnormal voice and emphasizing pronunciation,4 times a week and 1 hour each time.During the treatment,all patients were required to practice once at home on treatment days and twice on days without treatment.The voice handicap index (VHI),the western aphasia battery (WAB),the speech function portion of UPDRS-Ⅲ and the speech articulation assesstnent were used to evaluate the 2 groups before and after the 12 weeks ofintervention.Results Beforethe intervention there was no significant differencebetween the two groups in any of the measurements.After the interventionsignificant improvement was ohserved in all of these indicesin bothgroups.After treatment the average total VHI score of the intervention group (60.39±9.84) had improved significantly more than that of the control group,as did the WAB score for spontaneous speech (14.64±1.98),listening comprehension (112.67± 19.43),repeating (65.31±7.98),Name (39.89±9.84) and the average AQ scores (69.19±10.78) and UPDRS-scores [(1.39±0.61)] [of the intervention group than the control group [(71.03±11.01),(13.67±1.06),(111.53±29.61),(63.75±7.41),(37.89± 9.29),(62.14±10.21) and (1.82±0.82)].After the intervention,the average speech articulation scores of the intervention and control group were (77.61± 11.72) and (59.67± 10.04),significantly higher than those before the intervention [(54.36±10.71) and (53.98±9.92)],with the improveinent of the intervention group significantly higher than the control group.Conclusion Lee Silverman voice treatment can effectively improve the speech and life quality of patients with Parkinson's disease.

Objective To analyze the correlation between polymorphisms at position 4 and 14 in exon 2 of the p73 gene and susceptibility to human papillomavirus (HPV) infection.Methods Tissue specimens were obtained from the lesions of 83 patients with condyloma acuminatum and 11 patients with bowenoid papulosis,and blood samples from all the patients as well as 150 health checkup examinees with high risk for sexually transmitted diseases (STDs) at STD clinics (negative control group).PCR was performed to detect HPV DNA in lesional tissue specimens,followed by direct sequencing and nucleotide alignment using the BLAST program for the determination of HPV genotypes.To assess polymorphisms at position 4 and 14 in exon 2 of the p73 gene,DNA was extracted from all the blood samples,and the p73 gene was amplified by PCR with the primer shP73 followed by gene sequencing.The association between the polymorphisms and susceptibility to HPV infection was analyzed.Results Of the 83 tissue specimens from patients with condyloma acuminatum,42.2％ (35/83) were positive for HPV 6,and 41.0％ (34/83) for HPV 11.Among the 11 tisssue specimens from bowenoid papulosis lesions,5 were positive for HPV 16,and 3 for HPV 6.The p73 gene was successfully amplified and sequenced from all the patients with condyloma acuminatum or bowenoid papulosis as well as from 132 out of 150 health checkup examinees.There were three genotypes at position 4 and 14 in exon 2 of the p73 gene,including A4T14/G4C14,A4T14/A4T14,G4C14/G4C14,of which,A4T14/A4T14 was associated with a higher risk for condyloma acuminatum (OR 4.89,95％ CI 1.50-15.91) as well as bowenoid papulosis (OR 7.11,95％ CI 1.144-44.20),and G4C14/G4C14 with a lower risk for bowenoid papulosis (OR 0.16,95％ CI0.04-0.65),in patients with HPV infection.Conclusions The A4T14 allele in exon 2 of the p73 gene increases the risk for bowenoid papulosis and condyloma acuminatum,but no significant correlation is found between the susceptibility to high-or low-risk HPV infection and polymorphisms at the two positions in the p73 gene.

Taking α-asarone as model drug, mono methoxy polyethylene glycol-polylactic acid copolymer (mPEG-PLA) as the drug carrier material to prepare drug-loading nanoparticles by premix membrane emulsification for nasal administration. The prepared nanoparticles were spherical with smooth surface and average particle size of 360 nm. Polydispersity index (PDI) was 0. 030, average drug loading of (11.5 ± 0.045) % (n = 3), and the encapsulation efficiency of (86.34 ± 0.11) % (n = 3). X-ray diffraction and differential scanning calorimetry results showed that, α-asarone existed in mPEG-PLA carrier in amorphous or molecular state, different from simple physical mixture. In the in vitro release test in simulated human nasal cavity, α-asarone apis can be released quickly at close to 94% at 102 h, in line with the first-order kinetics (R² = 0.981 9). mPEG-PLA drug-loading nanoparticles release only 54%, with slow release effect, in line with Riger-Peppas model (R² = 0.967 9, n = 0.630 2), for non-fick diffusion, released by the spread of drugs and skeleton dissolution dual control. This provided the foundation for nasal drug delivery in vivo pharmacokinetic study.

Objective To summarize the preliminary experience of early anticoagulant therapy after endovascular stent graft exclusion for Stanford B type aortic dissection.Methods From June 2006 to June 2011,75 patients[ 65 males,10 fe males,mean age (59.1±13.5) years,range 22 -81 years ] under went endovascular stent-graft exclusion for Stafford B type aortic dissection in Shanghai Xinhua Hospital.Computed tomography angiography (CTA) was used to evaluate the lesions of aortic dissection before endovascular stent-graft exchusion.The descending thoracic aortic diameters were 22 mm to 42 mm [ mean (30.3±4.0) mm ].The distance from the breakage of dissection to the left vertebral artery(LSA)was longer than 1.5 mm in 29 cases,and shorter than 1.5cmin 46 cases.During the operation,left subclavian artery revascularization was per formed to patient,whose left vertebral artery was advantage and needs to be fully or partially covered From the second day after operation,asprin was given to patint,whose left subclavian artery was fully or partially coverd by endovascular stent-graft(no endoleak and residual distal tear).Early anticoagulant therapy lasted 3 months.The symptoms or signs about nervous system were observed in the early stage of postoperation,and the CTA was examined at postoperative 3 months.Results The operation succeeded in 75 patients.The diameters of aortic stent were 26mm to 46rmm[ mean(34.3±4.0) mm ].Left subclavian ar tery revascularization was carried out for 2 cases of all patients.The left subclavian artery was fully or partially coverd in 58 patients(fully covered in 19 cases,2/3 covered in 15 cases,1/2 covered in 24 cases),and 56 patints(no endoleak and residualdistal tear) were given anticoagulant therapy to prevent vertebral artery thrombosis.2 patients(2.7％)died in the early stage after operation.1 patient died of renal failure,1 patient died of dissection rupture,The duration of hospitalization was 4 to 19 days [ mean (7.9±3.5)days ].No neurological complications occurred in hospital.The follow-up period was 6 to 66 months.1 patient died during the follow-up,1 patient had recurrence of Stanford A type aortic dissection and was cured by ascending aorta and aortic arch replacement,1 patient had recurrence of Stanford B type aortic dissection and was cured by second endovascular stent-graft exclusion.All patients had no neurological complications,such as cerebral infarction and paraplegia.Concluslon Early anticoagulant therapy could safely and effectively prevent the neurological complications (such as cerebral infarction and paraplegia) related to vertebral artery thrombosis for Stanford B type aortic dissection patients whose left subclavian artery was fully or partially coverd by endovascular stent-graft.

OBJECTIVEThis study explored the dynamic expression of the E3 ubiquitin-protein ligase gene, Arkadia, in response to carbon tetrachloride (CCl4)-induced liver fibrosis in a mouse model and investigated the differential expression that occurs following treatment with the anti-fibrotic bone morphogenetic protein-7 (BMP-7).

METHODSThirty healthy male imprinting control region (ICR) mice were randomly assigned to three groups: normal (control; n = 6), CCl4-induced model group (model; n = 18), and CCl4-induced model with BMP-7 treatment group (treatment; n = 6). The model group was further divided into three subgroups (n = 6 each) for analysis at 4, 8 and 12 weeks after fibrosis induction. Liver fibrosis was induced by hypodermic injections of 60% CCl4 /peanut oil (5 mL/kg) to the hind legs of mice two-times per week in alternating legs for a period of 12 weeks. At week 9, the treatment group of CCl4-induced mice were given an intraperitoneal injection of BMP-7 (300 pg/g) simultaneously with that day's hypodermic injection of 60% CCl4 /peanut oil, and then every other day for a period of four weeks. The pathological changes in liver tissues were observed after staining with hematoxylin-eosin (HE) and Masson's trichrome. Messenger RNA (mRNA) and protein expression of Arkadia in liver were evaluated using reverse transcription-polymerase chain reaction and immunohistochemistry and Western blotting, respectively.

RESULTSMouse models of liver fibrosis were successfully established by CCl4 exposure. Arkadia, Smad7 and TGF-beta1 mRNA levels were up-regulated in the model group in a time-dependent manner (vs. control group), and BMP-7 treatment led to significant down-regulation of the CCl4-induced expression of the three genes (vs. control group: F = 812.80, 451.46, and 998.96, respectively; P less than 0.01). At week 12, the mRNA levels of Arkadia, Smad7, and TGF-b1 were significantly lower in the BMP-7 treatment group than in the model group (t = 12.108, 18.737, and 16.364, respectively; P less than 0.01). Arkadia, Smad7, and TGF-b1 protein staining was weak in the portal area of control liver tissue. In contrast, the model group showed significantly stronger staining for all three proteins in the portal area and in the cytoplasm of liver cells. The staining of Arkadia, Smad7, and TGF-b1 proteins was significantly lower in the treatment group (vs. control group: F = 8.399, 609.690, and 900.561, respectively; P < 0.01). At week 12, the protein levels of Arkadia, Smad7, and TGF-b1 were significantly lower in the treatment group than in the model group (t = 23.438, 11.667, and 42.889, respectively; P < 0.01).

CONCLUSIONArkadia expression gradually increased along with the development of liver fibrosis but was suppressed by treatment with the anti-fibrotic factor, BMP-7.
