Objective To summarize the experiences in clinical diagnosis and surgical treatment of chest cancers invading the superior vena cava (SVC). Method Retrospective study of 12 cases with chest cancers invading the SVC, SVC and innominate vein were reconstructed with prosthesis in 3 cases, the side wall of the SVC was excised and repaired in 9 cases. Results Complete resection was performed in 10cases,2 cases had incomplete resection. There was no death associated with operation in these patients. All patients were followed up for 1 - 7 years after operation,and 3 cases were lost to follow up,5 of remaining 9cases were dead because of relapse and metastasis, their median survival time was 8 months,other 4 cases lived, their median survival time was 42 months. Conclusions Patients with chest cancers invading the SVC should have surgical treatment of not only tumor resection but also the vessel reconstruction,the prognosis would be better than without surgical treatment. These patients have a high quality of life and live with long-term survival.

Objective To observe the anti-atherosclerosis effects of Guizhi Fuling Capsule. Methods 50 healthy SD male rats were randomly divided into 2 groups: normal group (n=12) and AS model group(n=38). The model of experimental AS rats was established by feeding high cholesterol diet and intraperitoneal injecting VitD3. The normal control group was fed by ordinary diet. AS model group was further divided into 3 groups randomly: AS group(n=12), control group (n= 12), and therapy group(n= 12). The therapy group was given Guizhi Fuling Capsule by intragastric administration.The control group was given simvastatin and captopril by intragastric administration. 0.9% NaCl was given to the AS group instead of Guizhi Fuling Capsule. The rats were killed at the 16th weekend, and their aorta arch and breast aorta were observed.Blood fat and serum levels of Endothelin-1 (ET-1), Nitric oxide (NO), high-sensitivity C-reactive protein (hs-CRP) were detected respectively. Immunohistochemistry technology was used for observing the expression of intercellular adhesion molecule- 1 (ICAM- 1 ) in breast aorta. Results The values of ET- 1, NO, hs-CRP and the amount of ICAM- 1 were (142.61 ±25.67)ng/ml, (66.05 ± 8.63) μmol/L, (2.86±0.40)mg/L, (0.29±0.05) in the normal group; (182.38±22.96)ng/ml, (28.70±4.49)μmol/L, (5.60±0.49)mg/L, (0.58±0.06)in the AS group; (154.37±21.11)ng/ml, (45.88±11.36)μmol/L, (3.66±0.34)mg/L, (0.37±0.04)in the control group and (152.13±23.23)ng/ml, (57.67±8.96)μmol/L, (3.70±0.40)mg/L, (0.36±0.04) in the therapy group respectively. The levels of ET-1, NO, hs-CRP and the amount of ICAM-1 have significant difference between the AS group and the normal group(P=2.47E-4, 6.02E-19, 1.11E-12, 2.51E-18). There was also significant difference between the control group and the AS group(P=0.005, 1.59E-14, 1.87E-5, 3.87E-14). The level of NO in the therapy group was higher than that in the control group (P=0.002). The levels of ET-1, hs-CRP and the amount of ICAM-1 did not have significant difference between the therapy group and the control group(P=0.81, 0.81, 0.48) Conclusion Guizhi Fuling Capsule has effects of Anti-atherosclerosis on rats with AS.

BACKGROUND:Human leukocyte antigen (HLA), the major histocompatibility complex of human, plays an important function in the transplant rejection. Decreasing the expression of HLA wil prolong the survival time of transplants.
OBJECTIVE:To design smal interfering RNA (siRNA) of HLA-A2 and to detect the effect of siRNA-HLA-A2 on the expression of HLA-A2.
METHODS:Four kinds of siRNA-HLA-A2 domains were designed, and recombinant lentivirus expression vector were formed. The 293T cells, highly expressing HLA-A2, were infected in vitro. Then the knockout efficacy of four domains was detected to select the highly efficient siRNA-HLA-A2 target sequences. The human embryo lung fibroblasts were cultured in vitro and infected with the lentivirus carrying the target sequence. The infecting efficiency of LV-siRNA-HLA-A2 was observed under the fluorescence microscope and the silence function of this siRNA in human embryo lung fibroblasts was detected by western blot analysis.
RESULTS AND CONCLUSION:According to the mRNA sequence of HLA-A2 in Genbank, three siRNAs were designed and synthesized. In vitro, the over expression of HLA-A2 in 293K cells was successful y silenced. The HLA-A2 expression in human embryo lung fibroblasts was also efficiently silenced after the human embryo lung fibroblasts were infected by the highly efficient siRNA of HLA-A2. The efficacy was up to 80%.

Objective To analyze the current situation of institutional care for people with disabilities in Shanghai, China. Methods Sec-ondary data were collected from the synthetical information platform of Shanghai Disabled Persons' Federation, including data about the res-idential institutions and people with disabilities living in the institutions from 2004 to 2015.

At the end of 2015, there was 368 residential institutions in Shanghai, providing institutional care for 5821 people with disabilities. People in the institutions were mainly with intelligence disability and mental disability, and mainly in 35 to 59 years old. Conclusion The institutional care for people with disabilities was generally in a good condition in Shanghai and met people's needs.

Background The tissue-engineered cornea is becoming the hot spot in the ophthalmologic field,while the research of corneal substitute is in the ascendant,because it is more similar to the corneal morpha and easy to survive in vivo.Objective This study was to investigate the biocompatibility of recombinant human type-Ⅲ collagen/poly9 ( 3-( methacryloylamino ) propyl dimethyl ( 3-sulfopropyl ) ammonium hydroxide ) ( PMPDSAH ) interpenetrating polymer network (IPN) (RHC-Ⅲ/PMPDSAH IPN) hydrogel as a tissue-engineered cornea in rabbit eye and its feasibility as the corneal substitute.Methods One hundred and eight rabbits were randomly divided into experimental group( 90 rabbits) and normal control group ( 3 rabbits),and 15 rabbits ( 30 eyes ) used as the donor corneas.RHC-Ⅲ/PMPDSAH IPN,NGF PMPDSAH IPN and corneal grafts were lamellarly transplanted into the right eyes in RHC-Ⅲ/PMPDSAH IPN group,NGF PMPDSAH IPN group and allograft group respectively.The corneal transparency and neovascularization were examined and scored under the slim lamp and compared among three groups using Kraskal-Wallis H test.The corneal epithelization time was observed and compared among these three groups using one way analysis of variance and LSD-t test.The histological examination of corneas was performed at the 3rd day,1st and 2nd week,1 st,3rd and 6th month after the surgery.The immunohistochemistry was used to detect the expression of K3 in cornea at the 6th month.Results The grafts were well attached in RHC-Ⅲ/PMPDSAH IPN group,NGF PMPDSAH IPN group and allograft group,and no rejection reaction was found throughout 6-month following up.Compared with normal control group,no significant differences were found in the scores of corneal opacification and neovescularization in these three groups (x2 =4.34,P =0.23 ;x2 =2.60,P =0.46 ) at the 6th month.NGF PMPDSAH IPN group achieved reepithelialization in (4.97±0.63) days and was obviously shorted than that in RHC-Ⅲ/PMPDSAH IPN group and allograft group ( t =11.97,P =0.00; t =5.80,P =0.00).The re-epithelialization time in RHC-Ⅲ/PMPDSAH IPN was (6.86±0.71) days,and that of allograft group was (5.87±0.43 ) days,showing a significant difference ( t =6.32,P =0.00).Hematoxylin-eosin staining results demonstrated that implanted materials integrated into the host corneal tissue well and support corneal epithelialization.Part of the material degraded at the 2nd week and degraded completely 1 month later.Regular alignment and distribution of collagen fibers were seen in the regenerated cornea and were similar to those of the normal stroma in 6 months.Immunohistochemistry showed the positive expression of keratin-3 in corneal epithelial cells.Conclusions RHC-Ⅲ/PMPDSAH IPN has a good biocompatibility without toxicity to corneal tissue.Furthermore,NGF can promote the corneal wound-healing and re-epithelialization.The material can be used as safe and reliable corneal substitute after improving the mechanical strength.

Objective To explore the rehabilitation needs and its influential factors of adults with physical disability in Shanghai, and to provide evidence for decision-making of the precise rehabilitation service. Methods From November to December, 2016, the rehabilitation demands, utilization rate and its influential factors of 390 registered people with physical disability were investigated with a questionnaire. Results The service of occupational rehabilitation met 62.34%and educational rehabilitation met 52.00%of the needs of adults with physi-cal disability at the age of 18 to 40 years. The service of occupational rehabilitation met 38.71%and educational rehabilitation met 35.29%of the needs of adults with physical disability of grade two. The main obstacle to the service utilization wasDo not know(67.34%). As a part ofotherreason, the cumulative frequency oftemporarily not neededaccounted for 16.41%in all reasons. Conclusion The rehabili-tation service should focus unmet needs to complete the community rehabilitation and health governance, and optimize the service system.

Objective To understand the present condition of preclinical dental undergraduate in-terns' AIDS-related knowledge. Methods The questionnaire was designed referring to domestic and foreign relevant questionnaires. The cluster sampling method was used to conduct the questionnaire survey among the undergraduates who started their clinical internship in July 2016 in three domestic colleges, using SPSS 14.0 statistical software to analyze it. Results In this survey, 144 questionnaires were distributed, and 144 ones were filled out and sent back. The survey results suggested that 97.22％ (140) of interns held a posi-tive attitude towards aiding HIV-infected patients despite that 96.53％ (139) of interns knew that dental medical staff was considered to be highly susceptible with HIV. In spite of the fact that most interns knew AIDS-related knowledge and protection measures, 40.28％ (58) of interns were not clear about incubation period of AIDS, and the average awareness of children's AIDS and methods to disinfect HIV-infected dental instruments was less than half in the interns. Meanwhile it was found that 86.81％ (125) of interns didn't perform well in terms of complying with the principles of confidentiality in AIDS prevention and treatment. Conclusion Dental clinical interns' attitudes towards AIDS-infected patients should be praised. Further-more, they should accept education about infection control to have a deeper understanding about AIDS-related clinical manifestations and legal knowledge in order to reduce the probability of nosocomial infec-tion of AIDS.

Objective To explore the correlation and significance of V312F locus polymorphism of PCSK9 gene in patients with coronary heart disease.Methods We selected 3560 patients with coronary heart disease who came to our hospital from January 2014 to January 2016 as the case group.They were divided into 5 subgroups:angina group,myocardial infarction group,silent myocardial ischemia group,ischemic cardiomyopathy group,and sudden death group,according to their anatomic and pathophysiological features.Data of 1 000 people for physical examination served as the control group.PCR assay combined with direct sequencing method was applied to test V312F locus polymorphism of PCSK9 gene.Logistic regression analysis was used to analyze relationship between V312F locus polymorphism of PCSK9 gene and types of coronary heart disease.The concentration of serum PCSK9 and lipids of the two groups were also measured.Results The serum levels of PCSK9,TC,TG and LDLC and ratio of positive family history in the case group were significantly higher than those in the control group,while the level of HDLC was lower than that of the controls (all P＜0.05).Indexes of sudden death subgroup in the case group showed the most significant changes,while asymptomatic myocardial ischemia subgroup showed the weakest changes.The frequency of genotype TT,GT and allele T in the case group was 3.4％,16.6％ and 11.7％,respectively,which was significantly higher than that in the control group (1.1％,10.2％ and 6.2％) (all P＜0.01).The highest frequency of genotype TT,GT and allele T was found in sudden death subgroup,and the lowest frequency of these indexes was found in asymptomatic myocardial ischemia subgroup (P＜0.05).Results of Logistic regression analysis showed that genotype TT in V312F locus of PCSK9 gene was related to the severity of coronary heart disease (OR =8.463,95％ CI from 3.505 to 17.854,P＜0.001).Conclusion The mutation of V312F (T/G)locus of PCSK9 gene might be related to the severity of coronary heart disease.

Objective To investigate the clinical results of the anterolateral thigh free flaps for the soft tissue coverage of Gustilo grade-Ⅲ B open bone fractures in lower extremities.Methods The anterolateral thigh free flaps were applied to treat 42 Gustilo grade-11Ⅲ B open fractures.Ten flaps were performed through an emergency procedure.Sixteen were performed at early stage and the other 16 were performed at later stage .The results of the therapy were analyzed after long time follow up. Results All limbs were salvaged and all the flaps survived without protracted course to obtain soft tissue coverage.The follow up ranged 11 to 47 months.The healing time of the bones were significant prolonged in the later stage therapy group compared with the emergency therapy group and the early stage therapy group.In the later stage therapy group,the incidences of the bone infection and nonunion were also higher than the other two groups,and the second stage bone transplantation to repair bone defect and nonunion were needed in 76% patients in this group.The lower limb functions of the later stage treated group were worse than those of the other two groups.Compared to the early stage treated group,better lower limb functions could be obtained in the emergency treated group. Conclusion Delayed soft tissue coverage resulted in higher incidence of complications.The immediate soft tissue coverage of severely injured limbs complicated by Gustilo grade-Ⅲ B open fractures and massive soft tissue defects had the advantages over traditional methods.Hard work though it was,one-stage soft tissue coverage using anterolateral thigh free flaps could obtain better lower limb function.
