Objective To evaluate the curative effect of nasal non-Hodgkin lymphoma(N-NHL) by four types of therapy such as pure chemotherapy, pure radiotherapy, chemotherapy combined with radiotherapy, and APBSCT combined with TBI. Methods One hundred and thirty five patients with nasal NHL were treated between 1980 and 2000. All patients received radiotherapy alone or chemotherapy alone or radiotherapy combined with radiotherapy or TBI combined with APBSCT. The median radiation dose to the nasal cavity was 56.0 Gy with a range of 35.2 to 75.5 Gy. Six patients received TBI combined APBSCT. The TBI dose was 8 Gy. Two patients received 30 Gy in nasal of the six patients. The chemotherapy regimen consisted of 2-6 cycles of COP, COPP, COMP, CHOP, COBDP. Results The local control rate and 5-year survival rate of the four groups of pure chemotherapy, pure radiotherapy, combined chemotherapy and radiotherapy and APBSCT combined with TBI were 12 %, 69 %, 76 %, 83 % and 9 %, 52 %, 63 %, 83 %. For the four groups, the best is APBSCT, then combined chemotherapy and radiotherapy group ,then pure radiotherapy, the last is pure chemotherapy. There is significant difference between the four groups(P

Objective To evaluate the effects of nasal non-Hodgkin′s lymphoma(N-NHL) treated with chemotherapy alone, radiotherapy alone, chemotherapy plus radiotherapy and autologous peripheral blood stem cell transplantation(APBSCT) combined with total body irradiation(TBI);and to analyze the impact factors of prognosis. Methods 135 patients were treated between 1980 and 2000. All were confirmed by histopathology as N-NHL, including 122 T cell in origin, 12 B cell and 1 NK cell in origin. The main radiotherapy portal was set in front of the nose with a spade-like protrusion, supplement with a portal next to the ear on one side or both sides. Combined portal in facial cervical area was first used when there was invasion of the oropharynx. The median dose to the nasal cavity was 56.0Gy with a range of 35.2 to 75.5Gy, with added 30Gy to the primary lesion in two patients. Six patients received TBI combined with APBSCT, with 8Gy in the TBI group. Chemotherapy, given before or during after radiotherapy or alone, consisted of 2-6 cycles of COP, COPP, COMP, CHOP or COBDP. Prognostic factors were analyzed with Cox model. Results The local control rate was 12%,69%,76% and 83% in chemotherapy alone, radiotherapy alone, chemotherapy plus radiotherapy and APBSCT combined with TBI, respectively(P=0.057).The 5-year survival rate was 9%,52%,63% and 83%,respectively(P=0.032). Multi-factor analysis showed that tumor extension and treatment methods were the most important prognostic factors besides Ann-Arbor stage, but gender, pathology, age and symptoms had little effect on prognosis .Conclusions Chemotherapy plus radiotherapy group achieves a better survival rate than radiotherapy alone. It is helpful to evaluate prognosis to make more detail subareas on basis of local extensions in Ann Arbor staging system.For some N-NHL patients with good financial condition, APBSCT combined with TBI is a good choice.

Aim To study the activation of Nrf2 in-duced by baicalein ( BAI ) , and its protection against carbon tetrachloride ( CCl4 ) , ethanol and acetamino-phen ( APAP )-induced hepatotoxicity. Methods A reporter gene assay was conducted in human normal liver L-02 cells to detect the activation of transcription factor Nrf2 induced by baicalein. APAP ( 10 mmol · L-1 ) , CCl4 (10 mmol·L-1 ) and Ethanol (100 mmol · L-1 ) were used to induce hepatotoxicity in L-02 cells. After the pre-incubation with Baicalein (0, 1, 10, 25, 50, 100 μmol·L-1 ) for 15 min, cells were administrated with or without those above hepatotoxins. 48 h later, cell viability was detected by 3-(4, 5-dim-ethylthiazol-2-yl ) 2 , 5-diphenyltetrazolium bromide (MTT) method. Results Baicalein (25, 50 μmol· L-1 ) induced the activation of Nrf2 ( P <0. 01 , P <0. 05) in the reporter gene assay. As compared with control, three hepatotoxins ( APAP, CCl4 , Ethanol ) all decreased cell viability ( P<0. 01 ) , and baicalein significantly reversed such decreases in a concentra-tion-dependent manner ( P<0. 01 ) . Conclusion Ba-icalein can induce the activation of transcription factor Nrf2 , which is probably one of the mechanisms con-tributing to the protection of baicalein against hepato-toxins (APAP, CCl4, Ethanol)-induced hepatotoxici-ty.

OBJECTIVETo evaluate the short-term efficacy and long-term preventive effect on recurrence in prevention and treatment of children allergic rhinitis treated with the multiple therapy at Dazhui (GV 14) as the main acupoint and acupoint plaster therapy.

METHODSOne hundred and twenty cases of children allergic rhinitis were randomized into a triple-strong stimulation therapy group and an acupoint plaster therapy group, 60 cases in each one. In the triple-strong stimulation therapy group, Dazhui (GV 14) was the main acupoint, combined with one of Feishu (BL 13), Zhiyang (GV 9) and Shenshu (BL 23) accordingly. The heavy needling technique was adopted with the three-edged needle, followed by heavy cupping and heavy moxibustion. The treatment was given once every 3 days, continuously for 10 times. In the acupoint plaster therapy group, the acupoints selected were same as the triple-strong stimulation therapy group. The self-prepared Chinese herbal plaster was used, 4 h to 8 h each one time, once every 3 days, continuously for 10 times. The changes in the symptom and physical sign scores were observed before treatment, after treatment and in 6 months follow-up visit after treatment in the two groups. The clinical efficacy was compared between the two groups.

RESULTSAfter treatment and in 6 months follow-up visit after treatment, the symptom scores, physical sign scores and symptom scores of each item were different signi ficantly as compared with those before treatment in the triple-strong stimulation therapy group (P<0.01, P<0.05), and the results in the triple-strong stimulation therapy group were better than those in the acupoint plaster therapy group (all P<0.01). In 6 months follow-up visit, the total effective rate was 94.6% (53/56) in the triple-strong stimulation therapy group and was 25.9% (15/58) in the acupoint plaster therapy group, indicating the significant difference (P<0.001).

CONCLUSIONThe triple-strong stimulation therapy at Dazhui (GV 14) achieves the superior effect on the prevention and treatment of children allergic rhinitis as compared with the acupoint plas ter therapy and has good long-term effect of the prevention from recurrence.

Objective To investigate the expression of peroxisome proliferator-activated receptors (PPARs) in epidermal keratinocytes of patients with psoriasis vulgaris and its significance.Methods Immunohistochemical method was used to examine the expression of PPARα,β/δand.γ in tissue specimens from the normal skin of 5 human controls,lesional and normal skin adjacent to the lesions of 17 patients with psoriasis vulgaris.A semi-quantitative analysis was carried out by image analyzer.Results Different levels of expression of the three PPAR isotypes were observed in the nuclei of epidermal keratinocytes of normal human controls.The expression intensity of PPAR α,β/δand γ was statistically higher in the epidermis of adjacent normal skin than that in psoriatic lesions(all P<0.01)and normal control skin(all P<0.01).Conclusions The decreased expression of PPARα may be associated with the overproliferation and parakeratosis of epidermal keratinocytes in psoriatic lesions,and PPAR β/δ and γ may display a synergistic effect on the maintenance of homeostatic proliferation and difierentiafion of epidermal cells.

Objective To estimate the effect of glycoprotein (transmembrane) nonmetastatic melanoma protein B (GPNMB) on the proliferation and migration of as well as melanogenesis in melanoma cells.Methods The expression of GPNMB was detected by immunofluorescence assay in two melanoma cell lines M14 and G-361,as well as in primary human melanocytes.Then,the three kinds of cells each were classified into three groups:experimental group treated with small interfering RNA targeting GPNMB (GPNMB-siRNA),negative control group treated with the negative control siRNA,blank control group remaining untreated.Methyl thiazolyl tetrazolium (MTT) assay,transwell invasion assay and spectrophotometry were performed to evaluate cell proliferation activity,invasion potential and melanin levels,respectively.Statistical analysis was done using Student's t test.Results GPNMB was expressed in both melanoma cells and melanocytes.The transfection with GPNMB-siRNA down-regulated the mRNA and protein expressions of GPNMB in,and markedly suppressed the proliferation and migration of,melanoma cells.In detail,the proliferative activity (expressed as the absorbence value at 570 nm) of M14 and G361 cells was reduced by 35％ and 40％ respectively,the migration activity of M14 and G361 cells by 49％ and 51％ respectively,and the melanin levels in melanocytes,M14 cells and G361 cells by 73％,82％ and 69％ respectively,in the experiment group compared with those in the blank control group.Conclusions The siRNA-mediated silencing of GPNMB could effectively inhibit the proliferation of,invasion of and melanogenesis in melanoma cells,which suggests that GPNMB plays critical roles in the initiation and progression of melanoma.

BACKGROUND: The cel density is one of the factors involved in the state of cel differentiation, and the effect of cel density on transforming growth factor-β1-induced epithelial-mesenchymal transition of HaCaT cells is stil unclear. OBJECTIVE: To observe the effect of cel density on transforming growth factor-β1-induced epithelial-mesenchymal transition of HaCaT cells. METHODS: HaCaT cells was seeded in 6-wel plates at low density of 103/cm2 and high density of 105/cm2 then treated by 2 μg/L transforming growth factor-β1 for 48 hours, thereafter observed the changes in cel morphology. The transcription levels of epithelial cadherin, tight junction protein-1, vimentin, neuronal-cadherin were detected by real-time PCR, and expression levels of epithelial cadherin and vimentin were detected by Western blot. RESULTS AND CONCLUSION: Cel gap of HaCaT cells grew larger after treated with transforming growth factor-β1 for 48 hours, and cel morphology was long spindle rather than polygonal in low-density group, while in high-density group without obvious morphological changes. The real-time PCR showed that the transcriptions of epithelial cel marker epithelial cadherin and tight junction protein-1 were suppressed when compared with the control group (P < 0.05), and the decreasing deree in the high-density group was higher than that in the low-density group (P <0.05), mesenchymal cel marker neuronal-cadherin and vimentin were upregulated in the high-density group and the low-density group when compared with the control group (P < 0.05), and there were no significant differences between high-density group and low-density group. Western blot results verified the changes of neuronal-cadherin and vimentin expression level. These results suggest that the high seeding density can inhibit transforming growth factor-β1-induced epithelial-mesenchymal transition of HaCaT cells.

Objective To investigate the safety and feasibility of not placing prophylactic drainage after colorectal anastomosis.Methods A total of 100 patients with colorectal cancer who were admitted to the Sichuan Provincial People's Hospital from July 2007 to March 2009 were randomly divided into drainage group (50 patients) and non-drainage group (50 patients) according to the random number table.A drainage tube was placed after colorectal anastomosis in the drainage group,while no drainage tube was placed in patients in the non-drainage group.The duration of postoperative hospital stay,mortality and morbidity of the 2 groups were compared.All data were analyzed by using the chi-square test or t test.Results Two patients(1 from each group) were excluded in the study,and no death or pulmonary infection were found in the remaining 98 patients.The numbers of patients whose course was complicated by anastomotic leakage and wound infection were 2 and 7 in the drainage group,and 1 and 5 in the non-drainage group.The duration of postoperative hospital stays were ( 11.5 ± 2.4)days in the drainage group and(10.6 ± 2.2)days in the non-drainage group.There were significant differences in the morbidity and duration of postoperative hospital stay between the 2 groups(x2 =0.00,0.38,t =1.428,P ＞ 0.05).Conclusion It is safe and feasible not to place a prophylactic peri-anastomotic drainage tube after colorectal anastomosis.
