Objective To detect the type of gene mutation of thalassemia in Kunming city.Methods Sixty-three cases highly suspec-tive of thalassemia were determined with the methods of ploymerase chain reaction(PCR) and reverse dot blot(RDB) for the type of gene mutation.Results According to gene analysis,35 cases were final diagnosed from 63 cases suspective of thalassemia.Among the total,4 cases were gene deficiency ?-thalassemia,and 30 cases were gene deficiency ?-thalassemia,and there was 1 case both ?-thalassemia and ?-thalassemia.There were 9 types of gene mutation with 15 gene combinations in 35 samples.The main type of ?-thalassemia was--SEA/??,there were 6 types with 11 gene combinations from the types of genes of ?-thalassemia,the highest incidence of gene mutation was 17 site,including 17 site homozygote,heterozygote and double heterozygote.Conclusions The thalassemia invasion of Yunnan has its characters,and it is valuable to launch further research.In the same patient,there are ?-thalassemia and ?-thalassemia,it signifies that those 2 types should be diagnosed in the same time,to prevent missed diagnosis.

Objective To evaluate the effect of recombinant human tumor necrosis factor receptor type Ⅱ:IgG Fc fusion protein (rhTNFR:Fc,trade name Etanercept) combined with methotrexate on levels of interleukin-17A (IL-17A) and tumor necrosis factor-α (TNF-α) in the serum and mononuclear cells of patients with moderate to severe plaque psoriasis.Methods A total of 30 patients with moderate to severe plaque psoriasis were enrolled from Department of Dermatology of Tenth People's Hospital of Tongji University between August 2014 and February 2016,and then were randomly and equally divided into Etanercept group and Etanercept + methotrexate group.The treatment lasted 24 weeks.Fifteen healthy blood donors served as healthy control group.Enzyme-linked immunosorbent assay (ELISA) and real-time quantitative PCR were performed to measure the serum levels and mRNA expression of IL-17A and TNF-α,respectively,in the patients of the above two groups before and after the treatment.Results Before the treatment,the serum levels of IL-17A and TNF-ct,as well as the mRNA expression of IL-17A and TNF-α in peripheral blood mononuclear cells (PBMCs),were all significantly higher in all the patients than in the healthy controls (all P ＜ 0.05).After the treatment,compared with the Etanercept group,the Etanercept + methotrexate group showed significantly lower serum levels of IL-17A (142.67 ± 14.82 vs.163.54 ± 23.18,P ＜ 0.05) and TNF-α (70.07 ± 25.02 vs.91.98 ± 14.62,P ＜ 0.05),as well as lower mRNA expression of IL-17A (1.12 ± 0.33 vs.1.56 ± 0.77,P ＜ 0.05) and TNF-α in PBMCs (2.50 ± 1.04 vs.3.61 ± 2.14,P ＜ 0.05).Conclusion Etanercept combined with methotrexate is superior to Etanercept alone in the treatment of psoriasis,and can reduce treatment duration and improve therapeutic effect,likely by down-regulating the expression of IL-17A and TNF-α.

Purpose: To investigate the relationship between rumination, coping strategies, and subjective well-being (SWB) and test the mediating effects of coping strategies on rumination and SWB in patients with breast cancer (BC). Methods: This cross-sectional study assessed rumination, coping strategies, and SWB using the General Well-being Schedule, the Chinese Event-Related Rumination Inventory, and the Medical Coping Modes Questionnaire in BC patients admitted to a tertiary general hospital in China. Results: SWB was positively associated with the total score for rumination (r = .32, p < .01), deliberate rumination (r = .75, p < .01), and confrontation (r = .58, p < .01). The relationship between rumination and SWB was mediated by confrontation (indirect effect = .74). Conclusion BC diagnosis can affect patient's SWB. These findings indicate that rumination and confrontation have direct and indirect effects on SWB. Therefore, psychological interventions focused on improving coping may increase SWB. Notwithstanding, larger longitudinal studies are needed to further examine the relationship between cognitive processes, coping strategies, and SWB.

OBJECTIVETo investigate the influence of drug properties on the encapsulation effiency (EE) and drug release of transfersomes for a proper transfersome preparation.

METHODTo prepare the transfersomes of colchicines (CLC), vincristine sulfate (VCR) and mitoxantrone hydrochloride (DHAD) with the same materials and methods, and then measure their EE. To find out the relationship between drug properties like solubility, molecular weight and charges, and EE. To performe the drug release experiments of various types of transfersomes in vitro, and compare their differences.

RESULTVCR and DHAD are lipophilic or hydrophilic, owing positive charges and large molecular weight, as a result, their EE are high, while CLC is amphipathic, neutral, and of small molecular weight, its EE is very low. As DHAD can insert into the membrane of transfersome, the drug release of DHAD-T in vitro is much slower than that of VCR-T.

CONCLUSIONTo prepare transfersomes with high EE, drugs that are lipophilic or hydrophilic, high molecular weight and opposite charges to the membrane should be chosen. Interaction between drugs and membrane will influnce the rate of drug release.

Objective To compare the mid-term clinical results of primary implantation of a selfexpanding nitinol stent and primary percutaneous transluminal angioplasty (PTA) for long range arteriosclerosis obliterans of the superficial femoral artery. Methods From December 2005 to February 2007,109 patients who had moderate-severe claudication or chronic limb ischemia (CLI)due to stenosis or occlusion of the superficial femoral artery were treated by endovascular technology. 53 patients (73 limbs) were treated by primary stenting and 56 patients (76 limbs)by PTA. We compared the clinical data of stenting group and PTA group at 6,12 and 24 months. Results The mean length of the treated segment was (16± 8)cm in the stenting group and(15±7)cm in the PTA group. At 6 months, the rate of restenosis on duplex ultrasonography was 13.7% in stenting group and 30.2% in PTA group (X2=4.09, P<0.05);at 12 months the restenosis rates were 25.5% in stenting group and 46.9% in PTA group(X2=4.75, P<0.05);at 24 months the restenosis rates on duplex ultrasonography were 38.1% in stenting group and 65.9% in PTA group(X2=6.66, P<0.01). Rutherford stages in stenting group were significantly better than those in PTA group. Conclusion In the mid-term, primary implantation of a self-expanding nitinol stent yielded results that were superior to those with PTA for arteriosclerosis obliterans or long range stenosis of the superficial femoral artery.

Objective To observe the primary clinical results of Gore （R） Viabahn endoprosthesis for atherosclerotic stenosis or occlusion in superficial femoral artery (SFA).Methods From March 2013 to November 2013,45 consecutive patients (54 limbs) who had ischemic symptom due to stenosis or occlusion of superficial femoral artery were treated by endovascular deployment of Gore （R） Viabahn endoprosthesis.We observed patency rate,improvement of Rutherford classification and ankle-brachial index,limb salvage rate and survival rate after 1,3 and 6 months.Results 43 patients (52 limbs)were followed-up,among which 32 patients(38 limbs)belonged to TASC Ⅱ type C or type D lesion.The mean (± SD) length of treated segment in 52 limbs was(19 ±4)cm.The rate of postoperative patency on duplex ultrasonography:one month,3 months and 6 months were 96.15％ (50 limbs),92.31％ (48 limbs)and 90.38％ (47 limbs) ; Ankle-brachial index increased from(0.32 ±0.20)to(0.68 ±0.18) (t =3.180,P ＜ 0.005) after 6 months ; at 6 months limb salvage rate was 96.08 percent (49 limbs),and survival rate was 97.67％ (42 patients).Conclusions Implantation of Gore （R） Viabahn endoprosthesis in atherosclerotic stenotic or occluded superficial femoral artery safely achieves a definite primary clinical effectiveness.

Objective To analyze the mid and long term results of endovascular procedures for diabetic below-the-knee lesions.Methods We retrospectively analyzed data of 762 patients (797 limbs in Wagner Grade 1 to 4) who suffered ischemic symptoms of diabetic below-the-knee lesions,admitted for endovascular procedures from Aug 2005 to May 2012.Technical success rate and complications,anklebrachial index,wound healing,limb salvage and survival were evaluated.Results 762 patients (797 limbs) underwent 857 endovascular procedures with immediate technical success in 805 times (success rate 93.93％).30 day complications included 33 cases (4.33％) of hematoma or pseudoaneurysm related to access site,20 cases (2.62％) of vasovagal reflex,38 cases (4.99％) of belowthe-knee arteriorrhexis,75 cases (9.84％) of inflow-limited dissection,23 cases (3.02％) of arterial embolism,4 cases (0.52％) of blue-toe sign.Postoperative mean ABI was improved significantly,from 0.33 ± 0.20 to 0.68 ± 0.17,P ＜ 0.005.722 patients (751 limbs) were followed up for more than 12 months (35 ± 23 months),wound healing rate within 3 months was 72.28％,limb salvage rate after 12 months was 85.62％,survival rate was 95.01％.Conclusions Immediate technical success rate of endovascular procedures for diabetic below-the-knee lesions is high,complications rate is low,medium and long term efficacy is satisfactory.

Objective To explore the effect and safety of transcranial approach for spheno-orhital meningioma. Design Retro- spective case series. Participants Thirty-two patients being operated with transcranial approach. Twenty-four cases were meningothelial meningiomas, 3 cases were fibrous meningiomas, 1 case was psammomatous meningioma, 2 cases were atypital meningiomas, 2 case were malignant meningiomas. Methods All patients underwent frontal-temporal craniotomy, the involved sphenoid wing bone and peri- orbit were removed to prevent recurrence. The superior orbital fissure and optic canal were decompressed, the dural and periorbital de- feet were repaired by autogenous temporal fascia or artificial dura. Main Outcome Measures Preoperative and postoperative exoph- thalmus and eyeball movement, the extent of tumor resection, the ratio of recurrence. Results The extent of tumor resection: 8 cases were Simpson gradeⅡ, 20 cases Simpson gradeⅢ, 4 cases Simpson grade IV. After surgery, proptosis were improved in all patients, ophthalmoplegia was found in 6 eases. There was no operation-related death or other significant complication. Tumor recurred in 6 cas- es. Conclusions Adequate exposure of the tumor and bony decompression of the cranial nerves can result from transcranial approach, all the involved bone should be removed in order to prevent recurrence. This approach is relatively safe and the ptoptosis are improved significantly. Complete surgical resection is difficult because of the involvement of the orbital apex, superior orbital fissure and cav- ernous sinus.

Objective To investigate the characteristics of the road traffic accident (RTA) casualties in Shanghai in 2003.Methods.The characteristics of RTA casualties were analyzed retrospectively on the data of Public Security Bureau and other related information.Results There were 54 197 RTA cases in 2003 with 1 406 death and 11 178 injured.The incidence rate and fatality of RTA was 311.48/10~4 and 11.17% respectively.The vehicle or population injury rate and mortality were 64.24/10~4,8.08/10~4,83.31/10~5 and 10.48/10~5,respectively.The fatality of suburb was higher than that of urban.Most of the casualties were bicyclist,pedestrians and motorcyclist,ranged mainly from 21 to 50 years old. Head injury and multiple traumas were the leading cause of death.Conclusion The RTA related injury had become a public health problem.The key strategies to decrease the fatality and disability of RTA were to propagandize the traffic safety perception in citizen and enforce the construction of rescue system for RTA including the EMSS.
