Objective To analyze the clinical data of 112 patients with adult-measles in the Af- filiated Shanghai Sixth People's Hospital and Third People's Hospital of Shanghai Jiaotong University from January to June in 2005,and to evaluate the epidemiologieal and clinical characteristics of adult- measles.Methods To retrospectively analyze the clinical data of 112 patients with adult-measles. Results Totally,112 measles patients were involved in this study,with male 63 and female 49 re- spectively.The gender rate was 1.3:1,average age about 32 years and the proportion of non-resi- dents was 40.18%.The peak of the incidence of disease emerged in April and May,and the positive rate of measle virus IgM antibody in serum was 96.43%.There were 97 patients(86.61%)who had the fever that beyond 39℃and 36 patients(32.14%)who had measle caused viral hepatitis.Conclu- sions There is a trend that the ages of patients that suffered from measle were postponed and the in cidences of disease are increased year by year,which maybe related to the nonstandard inoculation of measle vaccine,or the decrease of IgM antibody levels and so on.Meanwhile,serious toxemie symp- toms and liver damage can be observed.

Objective To investigate individualized and multi-phase management of recurrent epithelial ovarian carcinoma in order to improve survival of the patients. Methods From 1998 to 2002, 70 patients with recurrent epithelial ovarian carcinoma were enrolled in the present study. The treatments were divided into: (1) Induction of tumor remission:platinum sensitive patients were treated with paclitaxol + cisplatin (TP) or carboplatin + cyclophosphamide(CP)regimen; platinum resistant patients used Taxol + mitomycin(TM)or etoposide+ mitomycin(VM)regimen. Resection of tumors was done in an attempt to reduce the residual tumor with a diameter less than 1cm. Local radiotherapy was performed for those with residual tumor and who achieved clinical response after chemotherapy or surgery. (2) Consolidation therapy: chemotherapy with lower doses was administrated after disease remission. Interferon was used as immunotherapy during chemotherapy and radiotherapy. Survial analysis was done. Results (1) The 1, 2, 3, 4, 5-year survival rates were 67%, 51%, 45%, 38%, 32% . Median survival was 38.57 months. (3)The 1,2,3-year progression-free survival rates of the research arm were 41%, 37%, 24%. Median progression-free survival was 12.00 months. (4) Multivariate analysis revealed that platinum-free interval (P

Objective To investigate and compare the argumentativeness and attitudes towards thinking and learning between clinical nurses in general adult wards and wards for patients requiring particularity healthcare for the identification and development of core communication skills.Mettods “Argumentativeness Scale” and “Attitudes toward Thinking and Learning Survey” in Chinese were used to measure a convenience sample of 504 clinical nurses in seven hospitals.Results The scores in items reflecting rationality,positivism,empathy and acceptance in 247 nurses in wards for particularity heahhcare were significantly different from those nurses working in internal medical wards for adults with internal medical problems.Conclusions To develop harmonious interpersonal relationships in nurses,we should strengthen competencies in emotional regulation and rational thinking in nurses in wards for adults with in-ternal medical problems.

Gene therapy refers to the introduction of normal genes into human target cells for correcting gene defects or exerting therapeutic action,and thus achieves the goal of treatment of disease.Bone marrow stromal cells (BMSCs) are stem cells that possess self-renewal and multi-directional differentiation potential and easy to amplify in vitro,and they also express many therapeutic exogenous genes in vitro or in vivo.So BMSCs have been regarded as an ideal target cell of cell and gene therapy.This article reviews the biological characteristic of BMSCs,some commonly used gene therapy vectors and their applications in gene therapy of central nervous system diseases.

ObjectiveTo find out if the immune system derived thyroid stimulating hormone(TSH) β splice variant(TSHβ-Ⅴ) would be regulated by circulating thyroid hormone levels to get a further understanding of the function and mechanism of this TSHβ-Ⅴ in thyroid homeostasis.MethodsA total of 20 weaning Balb/c mice (half male and half female) were selected and randomly divided into two groups according to their body mass and gender(n =10).Mice of control group were fed with common diet and deionized water.Mice of the low-iodine(LI) group were fed with low-iodine diet(containing iodine 20 - 40 μg/kg,iodine-intake about 0.25 μg/d) and deionized water.The experimental period was 3 months.At the end of the experiment,mice were executed and the blood was collected to observe the levels of TSH and thyroid hormone by chemiluminescence immunoassay (CIA) ; bone marrow (BM),peripheral blood(PBL),thyroid gland and pituitary were collected to assay the TSHβ-Ⅴ mRNA expression by real-time quantitative reverse transcriptase polymerase chain reaction (RT-PCR).ResultsThe serum free thyroxine(FT4) and total thyroxine(TT4) levels in LI group of mice[(0.47 ± 0.70)nmol/L,(2.41 ± 0.28)pmol/L] were significantly lower than that of the control group of mice [(55.2 ± 3.68) nmol/L, (32.72 ± 1.02) pmol/L,t =43.81,86.04 、all P ＜ 0.01 ] and the serum total triiodothyronine(TT3) and free triiodothyronine(FT3) reduction in LI group of mice[ (0.76 ± 0.08)nmol/L,(4.01 ± 0.40)pmol/L] were significantly lower than that of the control group of mice [ (1.10 ± 0.06)nmol/L,(5.40 ± 0.38)pmol/L,t =9.81,7.5 1,P ＜ 0.01 ].Iodine insufficiency strongly elevated the serum TSH in LI group of mice[ (35.67 ± 17.39)mU/L] than that in control group of mice[ (0.24 ± 0.10)mU/L,t =- 6.11,P ＜ 0.01 ].The mRNA levels of TSH β-Ⅴ in BM (9.62 ± 0.60) and in PBL( 9.25 ± 0.83 ) of LI group of mice were lower than those in control group of mice (7.69 ± 0.36,7.11 ± 0.41,t =6.77,5.64,P ＜ 0.01),while the mRNA level of TSH β-Ⅴ in pituitary of LI group of mice (1.99 ± 0.61) was increased compared with that in control group of mice (5.75 ± 0.98,t =- 8.02,P＜ 0.01).Compared with control group of mice(9.12 ± 0.62),the level of thyroid TSH β-Ⅴ mRNA in LI group of mice (9.32 ± 0.91 ) was not significantly changed (t =0.45,P ＞ 0.05).There was no detectable native TSHβ in BM,PBL and thyroid.The mRNA level of native TSHβ in pituitary in LI group of mice( - 7.17 ± 1.78) was dramatically elevated compared to that in control group of mice( - 1.43 ± 0.51,t =- 7.60,P ＜ 0.01 ).ConclusionsThe mRNA levels of TSHβ-Ⅴ are suppressed in BM and PBL in low iodinediet induced hypothyroidism mice,which suggest that immune system derived TSHβ-Ⅴ may be more important thannative TSHβ in immune-thyroid regulation.

Objective To observe the different effects of iodine excess on inducing two strain mice thyroiditis. Methods NOD and Balb/c mice, each having 14 mice, were divided into NaI and control group. The mice were given 0.05% NaI water for 8 weeks in NaI group. RIA and ELISA were used respectively to detect TT4, TgAb, TPOAb and TSH level in serum. Morphology changes of thyroid and apoptosis of thyrocytes stained by immunohistochemistry were observed under light microscope. Lymphocytic proliferation of cervical lymph node and spleen to responding to Tg were detected by MTr method. Results After intake of iodine water for 8 weeks, NOD and Balb/c mice showed relative quality of thyroid in Nal group[(104.83±14.52), (155.79±20.77)mg/kg]obviously increased compared with control group[(71.80±20.42), (105.15±21.98)mg/kg, t values:-3.293,-4.429, all P< 0.01)], enlarged follicular lumen with colloid accumulation were observed in thyroid. Serum level of TT4 in Nal group [(29.52±4.42), (19.53± 2.35)nmol/L]to control group[33.40±5.38), (23.47±6.22)nmol/L]of NOD and Balb/c mice showed a decreasing tendency(t values: 1.374,1.567, all P > 0.05). TSH of Nal group showed an increasing tendency in Balb/c mice[(4.14±1.71)μg/L, compared with control [(3.55±1.41)μg/L, t values:-0.705, P > 0.05]and obviously increased in NOD mice [(6.98±0.66)μg/L, compared with control[(555±056)μg/L, t values:-3.562, P< 0.01], but no change of TgAb and TPOAb level in Nal group(1281,1364 cpm, 2.50×103, 0.14×103U/L were observed, compared with control(1297,1220 cpm, 3.17×103,0.03×103 U/L; Zvalues:-0.081,-0.703, -0.244,-1.293, all P > 0.05). In NOD mice NaI group, apoptosis of thyrocytes was more intense than Balb/c mice, obvious infiltration of lymphoeytes, disorganization and focus fibrosis was seen in thyroid. The cell amount of NaI group increased in NOD mice lymph node and spleen cells[(1.100±0.014), (1.076±0.033)]were more than that in the control group [(0.993±0.011), (1.005±0.003), t value:-11.672,-4.314, P < 0.01). Conclusions Iodine leads to enlargement of thyroid and malfunction of thyroid in Balb/c mice. Besides, NOD mice have generate inflammatory reaction in thyroid and produced sensitized lymphocytes to Tg. Iodine excess can induce NOD mice to occur autoimmune thyroiditis.

Objective To discuss the mid?to long?term results and possible prognostic factors of Bernese periacetabu?lar osteotomy for adolescents and young adults with developmental dysplasia of the hip. Methods Bernese periacetabular os?teotomy was performed on 162 patients (171 hips) with hip dysplasia from August 1997 to July 2009. Follow?up data was ac?quirable completely in 123 cases (137 hips), including 30 males (33 hips) and 93 females (104 hips). Age of surgery was 12-48 years (average 27.1 years). The X?ray radiographs and Harris scores were recorded preoperatively and at the last follow?up. The lateral center?edge angle (LCE), acetabular incline angle (AI), continuity of Shenton's line were also recorded. The grades of the hip osteoarthritis were classified by T?nnis classification. Insufficient corrections of osteotomy, excessive corrections of osteotomy, nonunion of the pubis, nerve injuries, and vascular injuries were recorded as complications. Results All the con?tactable cases was followed up again in June and July in 2014. Follow?up duration was 5-17 years (mean, 8.1 years). The LCE angle improved from 7.13° ± 8.86° preoperatively to 30.17° ± 14.98° at the final follow?up. The T?nnis acetabular incline angle decreased from 27.84° ± 12.85° preoperatively to 7.06° ± 10.58° at the final follow?up. The continuity of Shenton's line was in?tact in 106 cases postoperatively, compared with 87 cases preoperatively. Harris score improved from 83.34±9.82 preoperative?ly to 92.79±7.05 at the last follow?up. There was significant correlation between preoperative Harris score and Harris score at the last follow?up. Early complications were observed in 15 cases (15 hips), along with 17 cases (17 hips) of progressions of hip osteoarthritis. Survival rate of the hip at the last follow?up was 97.8%. Conclusion Bernese periacetabular osteotomies can significantly improve bone coverage and joint function of hip dysplasia patients with low rate of short?term complications. Further?more, there was little osteoarthritis progression observed, with good survival rate of the joint in mid?to long?term follow?up. Lower pre?operative Harris scores and higher pre?operative T?nnis classifications are important prognostic factors for post?operative pain.
