Parkinson's disease(PD) is a common neurodegenerative disorder with no effective protective treatment,characterized by a massive degeneration of dopaminergic neurons in the substantia nigra(SNpc) and the subsequent loss of their projecting nerve fibers in the striatum.The major neurochemical manifestation of this disorder is the loss of the neurotransmitter dopamine(DA) in the striatum as a result of the progressive degeneration of the dopaminergic neurons in the substantia nigra.There have been significant progresses in recent years reporting on the use of mesenchymal stem cells(MSCs)in gene therapy,with specific application towards PD.MSCs,a kind of multipotent adult progenitor cells,are considered as a useful vehicle for cell and gene therapy because of their multiple differentiation potentiality and self-transplantation.The present study was focused on treating rat model of PD using human tyrosine hydroxylase gene(hTH),human aromatic L-amino acid decarboxylase gene(hAADC) and human GT Pcyclohydrolase I gene(hGCH-I) engineered MSCs,in order to provide a better understanding about the application of these cells in the therapeutic benifit of PD.The gene of hTH,hAADC and hGCH-I were introduced via recombinant adeno-associated virus(rAAV) infection into the MSCs in vitro.The genetically modified MSCs expressing hTH,hAADC and hGCH-I were transplanted into the striatum of PD rat models.The behavior,the nigra-striatal level of DA and its metabolite were detected.The results of present study were shown as follows:hTH,hAADC,hGCH-I and LacZ gene were transfected into MSCs with adeno-associated virus vectors.The HEK293 packaging cells(ATCC) were transfected with the plasmids of pAAV-hTH,pAAV-hAADC,pAAV-hGCH-I,pAAV-LacZ,pAAV-RC,pHelper by using calcium phosphate precipitation.Titer was detected using HT1080 cells.Viral particles were collected and used to infect MSCs.The purified modified MSCs expressing the three kinds of genes were selected separately and were grafted in the striatum of the PD model rats in the lesion side.The MSCs genetically modified suvived well 12 weeks after transplantation.The improvements of the behavior were observed every week after transplantation.Compared with the control group,the rounds of asymmetric rotation after apomorphine administration decreased in the groups double or triple genes engineered MSCs grafted(p

AIM:To observe the effect of fresh amniotic membrane transplantation ( FAMT) in acute ocular chemical burns.
●METHODS:A prospective study of 25 consecutive cases (36 eyes) with acute ocular chemical burns were treated with FAMT. The clinical efficacy was observed such as the time of amniotic membrane absorbed, corneal epithelialization & transparency, visual acuities and complications.
●RESULTS: With follow-up ranged from 3 to 6mo, 31 eyes′ amniotic membrane were dissolved in 2wk (86%). A total of 33 eyes showed corneal epithelialization in 4wk ( 92%) , 3 eyes showed persistent corneal epithelial defects and need secondary limbal stem cell transplantation or corneal transplantation ( 8%) . A total of 10 eyes showed superficial corneal vascularization (28%), 6 eyes′ cornea were opacity in part (17%), and one eye was symblepharon (3%).
●CONCLUSION:Early FAMT is an effective treatment in the management of acute ocular chemical burns to support epithelial healing, restore ocular surface integrity with potential to improve vision and reduce the incidence of complications. Furthermore, FAMT has advantages of easily obtain and convenient usage, which is suitable in local hospital of our country.

OBJECTIVETo evaluate the clinic outcome and indications of sternocleidomastoid (SCM) myocutaneous flap for reconstruction after resection of carcinoma in floor of mouth.

METHODSThirty-two patients underwent SCM myocutaneous flap for reconstruction of the floor of mouth were reviewed. According to the clinical data and the follow-up, the appearance and function were analyzed.

RESULTSOnly one myocutaneous flap was partial necrosis in termination of the flap, and growth with granular. In eight cases, partial epidermal loss over the skin paddle occurred with secondary healing with mucosal epithelium. All patients had oral diet with good separation of the oral floor and the tongue, and had no difficulty in speech intelligibility. The patients' appearance, function and the overall quality of life were improved.

CONCLUSIONThe SCM myocutaneous flap appears to be easy to use and suitable for reconstruction of the defect after resection of oral floor carcinoma, the indications of this flap should be selected carefully.

0.05).Seroquel showed high incidence rate of drowsiness,dizziness and weight gain(26.1%,23.9%,17.3%),chlorpromazine showed high incidence rate of extrapyramidal side effect,pyknocardia and erect collapse(60.9%,39.1%,32.6%).CONCLUSIONS:There was no significant difference of curative effect for the treat-ment of schizophrenia between seroquel-treated group and chlorpromazine-treated group,but seroque showed low side effect and high safety.

The uhrastructure and atrial natriuretic peptide(ANP)mRNA in myocardium of streptozotocin-induced diabetic rats were studied along with the effect of rosiglitazone.It was found that the myocardial ultrastructure was demaged in diabetic rats.Rosiglitazone may ameliorate the lesion in myocardium,and lower the ANP mRNA in diabetic rats(1.14?0.05 at 6 weeks and 1.12?0.09 at 10 weeks vs 0.97?0.14,both P

Objective To investigate the current situation and variation in the tendency of Kaschin-Beck disease (KBD) in Shanxi province, to assess the effectiveness of prevention measures, and to provide evidence for making scientific and effective tactics in prevention and control of the disease. Methods In 2008, according to "The National Technical Scheme for Kaschin-Beck Disease Control in 2007", children aged 7 - 12 years underwent clinical and X-ray examination in two historical severe KBD areas of Shanxi province, the observed position on Xray film was finger bone and carpal bone. Adults aged 16 years and above were clinically examined in 50 villages of 13 counties of KBD areas, Shanxi province. The diagnosis was based on "Diagnostic Standard of Kashin-Beck Disease"(GB 16003-1995), the adult patients were degreed according to the state of illness and divided into different groups according to their ages. Results A total of 181 children were examined, none of them was diagnosed as clinical KBD patient. The positive cases of X-ray were 2, X-ray detectable rate of metaphysis was 1.1% for children.In the 50 villages 13 871 of adults were examined and 801 KBD patients were found and the detectable rate was 5.77%. The detectable rate increased with age. The adult patients distributed mainly in the subpopulation aged 51years and above and these patients accounted for 70.66% (566/801) of total people examined. Degrees Ⅱ and Ⅲ patients at these ages accounted for 71.78%(206/287) of total degrees Ⅱ and Ⅲ patients. Conclusions The state of child KBD in Shanxi is under the national control standards. The detectable rate of adult KBD is higher. Relevant departments should pay close attention to the treatment of adult patients.

Molecular imprinting technique (MIT) involves the synthesis of polymer in the presence of a template to produce complementary binding sites in terms of its size, shape and functional group orientation. Such kind of polymer possesses specific recognition ability towards its template molecule. Despite the rapid development of MIT over the years, the majority of the template molecules that have been studied are small molecules, while molecular imprinting of proteins remains a significant yet challenging task due to their large size, structural flexibility and complex conformation. This review, we summarized the research findings over the past years, and discussed the nano-reinforcing materials used to prepare molecular imprinting of proteins and the perspective of these nano-reinforcing materials.
