Studies suggest that some patients with synchronous oligometastatic lesions in brain,adrenal gland,lung,et al,may achieve long-term survival via complete resection. Some subgroups of patients with stage Ⅰ or Ⅱ primary lesions, without or with single mediastinal lymph node involvement and with resectable oligometastatic lesions may benefit from surgery. A better understanding of the prognostic factors related may help improve surgical interventions.

Objective To evaluate the biological behavior,clinical features,and diagnosis and treatment of inverted urothelial papilloma. Methods A total of 113 cases of urothelial inverted papilloma were included in this retrospective analysis.Of them 102 were male and 11 were female,with a mean age of 55 years.Among the 113 cases of urothelial inverted papilloma 108 had the papilloma at low urinary tract.Of these cases,88 were treated by TURBT,6 by TURBT and TURP,10 by partial cystectomy,4 by partial cystectomy and prostatectomy,1 by total cystectomy.Five cases who had the papilloma at upper urinary tract underwent nephroureterectomy. Results 86 cases were followed up 0.5 to 10 years.Intravesical recurrentce occurred in 5 cases.Of them 2 cases developed malignance and 1 case underwent total cystectomy. Conclusions Inverted urothelial papilloma is a benign tumor,which appears male predominant.Most of the lesions localize at the bladder.The diagnosis can be established mainly by cystoscopy.Most of the inverted urothelial papilloma can be cured by TURBT with a satisfactory prognosis.

The change of Dietary pattern matched to a change in diseases spectrum of Chinese people in recent years. For improving the function of clinical nutrition branch in hospitals, in accordance with the change in the spectrum and patients' characters, we need to adjust the clinical nutrition treatments individually, to enhance the health education and consultation, to set new dietary pattern for people rationally, and to carry out the scientific research in the field of the relation between concerned chemical elements of organical foods and human health status in general, in order to reach the advanced hospital standards.

Objective To provide scientific evidence for nutrition therapy and health education for patients with type 2 diabetes mellitus (T2DM).Methods Based on body mass index (BMI),75 newly admitted T2DM patients were assigned to the normal body-weight group and the over-weight group.Three days before admission,their dietary status was investigated.The average energy intake was compared with the average standard supply.The energy from protein,fat or carbohydrate and the intake of fiber were compared with the recommendations from the American Diabetes Association (ADA).The intake of other nutrient was compared with the recommended nutrient intakes (RNI) or adequate intakes (AI).Results Compared with the standard supply,the average energy intake of the normal body-weight group was significantly decreased (t =2.61,P ＜ 0.05 ),however the average energy intake of the overweight group was significantly increased (t =3.91,P＜0.05).The percentage of energy from protein of the two groups was significantly higher than target levels ( t values were 13.23,21.13 respectively; all P ＜ 0.05 ) ; the percentage of energy from protein of the two groups was significantly higher than target levels (t values were 5.36,10.66 respectively ; all P ＜ 0.05 ) ; however,the percentage of energy from carbohydrate was lower in both groups ( t values were 6.94,15.76 respectively; all P ＜ 0.05 ) ; the average intake of fiber were also lower in both groups (t values were 26.54,40.80 respectively ; all P ＜ 0.05 ).ConclusionThe participants showed insufficient knowledge on healthy diet.Health education could play a role in balanced diet and energy intake.

Objective:To lay background for studying rejection mechanisms in xenotransplantation, class II DQA genes of swine leukocyte antigens (SLA) of three Chinese pig strains GXP, GZP and YNP were cloned and sequenced.Methods:RT-PCR was performed to proliferate SLA-DQA genes (GXPDQA, GZPDQA and YNPDQA),which were cloned into pGEM-T Easy vector for sequencing and analysis.Results:All three allelic sequences examined, are not identical to those reported, which allows the sequences receiving their accession numbers from GenBank as AY102473, AY102474 and AY102475, which encompass an open reading frame of 765, 768 and 768 nucleotides respectively.Conclusion:Three new alleles of SLA-DQA genes were obtained. Analysis of the amino acid sequences of swine, human and mouse DQA (or equivalent) also indicated that GXPDQA, GZPDQA and YNPDQA were more similar to human DQA than mouse H-2-A?, which might provide an understanding of how the immune system evolved.

Objective: To investigate the effects of lycopene on T lymphocyte subpopulations and pulmonary alveolar macrophagic (PAM) functions in rats with acute lung injury (ALI). Methods: Rats were randomly divided into the following groups. (1) Control group, (2) ALI model group, (3) Low dose group, (4) Mid dose group and (5) High dose group. Control group and ALI model group were treated with solvent of lycopene, and the other groups were gastrically incubated with lycopene. Thirty-five days later, control group were given physiological saline, ALI model group and lycopene administrated groups were injected with lipopolysaccharide (LPS) (6.0 mg/kg) to induce ALI. One hour, four hours or six hours after LPS or physiological saline challenged, abdominal aorta blood for measuring lymphocyte subpopulations and bronchoalveolar lavage fluid for measuring function of PAM were gathered respectively. Results: (1) At h 1, the percentages of CD3+,CD4+ and CD8+ of lycopene administrated groups compared with control group were not significantly different. At h 4, the percentage of CD4+ was similar to that at h 1. As for the percentages of CD3+, except high dose group [(28.8?9.9)%] was significantly lower, low dose, mid dose and ALI model group showed no significant difference compared with control group[(39.5?4.5)%]. The percentages of CD8+ of ALI model and lycopene administrated rats, separately (10.2?3.9)%,(10.3?2.8)%,(9.8?2.8)%,(10.1?3.5)%, had been significantly reduced compared with control group[(15.1?2.5)%]; between ALI model and lycopene ad-ministrated groups there was no significant difference. The instance at h 6 was the same as that at h 4. The percentage ratios of CD4+ T-lymphocyte to CD8+ T-lymphocyte of ALI model rats were not significantly different compared with control group or lycopene administrated groups at h 1 and h 6. At h 4, the ratio of the CD4 + and CD8 + in Low dose and Mid dose groups had significant difference and ALI model, high dose hadn’t when they were compared with control group. (2) Lycopene increased the phagocytic function of PAMs significantly at h 1(P

Objective To establish the type Ⅱ collagen specific T cell line of Wistar rat and observe its effect on transferring arthritis.Methods The Wistar rats were immunized with emulsified chicken type Ⅱ collagen (CCⅡ) in complete Freund′s adjuvant by intradermal injection to induce the rat model of collagen induced arthritis (CIA).The lymphocytes were obtained from mesenteric lymph nodes of CIA rats,and the type Ⅱ collagen reactive T cell line was selected and propagated by CCⅡ stimulating in vitro .The proliferation response and phenotype were analyzed by 3 H TdR incorporation and fluorescence activated cell sorter (FACS).The onset of arthritis and pathological characteristic in ankle joints of recipient rats were observed with naked eye and histochemical examination.Anti CCⅡ antibody in serum was assayed by enzyme linked immunosorbent assay (ELISA).Results A T cell line was successfully established.The results of FACS labeled with fluorescent antibodies showed that 98 2% of the line cells were T cells,of which 89 7% were CD4 + T cells.The results of adoptive transfer showed that the incidence of arthritis was 50% when the injected cell number was 5?10 7,meanwhile the level of anti CCⅡ antibody in serum was elevated more than that of the control.Conclusion A cell line has been successfully established.The result of arthritis transferring by T cell line shows that the T cell plays a great role in the pathogenesis of CIA and provides a research datum for rheumatoid arthritis therapy with T cell vaccine.

Objective To investigate the protective effect of carnosine on radiation-induced lung injury in mice.Methods A total of 108 C57/BL female mice were randomly divided into 4 groups:control group without treatment,irradiation alone group,irradiation + carnosine group (15 mg·kg-1·d-1),and carnosine alone group (15 mg· kg-1· d-1).There were 18 mice in control group and 30 mice in every other group.Whole lung anterior chest was irradiated with a single dose of 13 Gy 10 MV X-rays.The mice were administered with carnosine (15 mg· kg-1· d-1) at 30 minutes before irradiation and then garaged once a day until the end of the experiment.The control group was given with saline.At 7,28,and 56 d after irradiation,6 mice of control group and 10 mice of each other group were killed.A portion of lung tissues were stained with HE and other part of lung tissues were used to detect the levels of SOD.Meanwhile,TGF-β1 and TNF-α in the serum were detected with ELISA.Results Different levels of inflammation factors were expressed in the lung tissues of irradiation group and irradiation + carnosine group at 56 d after irradiation,but the inflammation in the irradiation + carnosine group was significantly lighter than that in the irradiation group.Among (7,28 and 56 d) after radiation,TGF-β1,TNF-α,and SOD levels in different groups had significant differences.At the same time point after irradiation,the level of SOD in lung tissue of irradiation + carnosine group was significantly higher than that of irradiation group (F =4.33,4.19,3.34,P ＜0.05),but the levels of TGF-β1 and TNF-α in serum were reduced.Conclusions Carnosine can prevent and inhibit radiation-induced lung injury in mice by increasing SOD and reducing TGF-β1 and TNF-α.

Objective To explore the clinical value of CEUS guided biopsy of lymphoma in anterior mediastinum.Methods The data of 36 patients with lymphoma of anterior mediastinum underwent biopsy guided by CEUS and 36 patients by conventional ultrasound retrospectively.The successful rate of biopsy and rate of complication occurence were compared between the CEUS group and conventional ultrasound group.Results The successful rate of biopsy in CEUS group was 100％ (36/36),including 26 non-Hodgkin's lymphoma (NHL),10 Hodgkin's lymphoma (HL).The total times of puncture were 60 in 36 patients.The rate of complication occurrence was 11.11 ％ (4/36).The successful rate in conventional ultrasound group was 88.89％ (32/36),including 22 NHL,14 HL.The times of puncture were 91 in 36 patients.The rate of complication occurrence was 41.67％ (15/36).There were significant differences in successful rate and the rate of complication occurrence between two groups (x2 =4.235,8.651,P=0.040,0.003).Conclusion CEUS can reflect the microcirculation of lymphomas in anterior mediastinum,and can guide targeted biopsy.It can improve the successful rate of biopsy and reduce the complications.

Objective To investigate the family burden of patients with severe mental illness. Methods 148 patients with schizophrenia and bipolar disorder were assessed with Family Burden Scale of disease (FBS). Results Family burden broadly exists among those patients with schizophrenia and bipolar disorder, and the burden tends to involve several dimensions, including family relations (51%), home entertainment (50%), daily routine (45%), economic burden (43%), mental health of family members (36%) and physical health of family members (32%). Conclusion Integrated psychological and social intervention should be made to reduce the family burden of patients with schizophrenia and bipolar disorder.
