Purpose:To determine the efficacy of paclitaxel in human bladder cancer lines and to investigate the mechanism by which paclita xel induce apoptosis in human bladder cancer cells. Methods:BIU-87, 5637, T24 and EJ bladder cancer cell lines wer e cultured by techniques of cell culture in vitro. The cytotoxic activity an d apoptosis induction abilities of paclitaxel were analyzed by MTT and Annexin- V assay as well as DNA cytometry , respectively. The effects on the cell cycle w ere assessed by flow cytometry of propidium iodide. The expressions of Bcl-2, B ax, p53 and Caspase3 proteins were determined by flow cytometry immunofluorescen ce. Results:Paclitaxel dose-dependent inhibition of cell prolifera tion was seen.Paclitaxel induced G_2/M arrest (71.29% and 64.57%) which was maximal in 5637 and EJ cell lines. While paclitaxel at 1?g/ml concentration ex posure to 5637 12h, 14h and 48h respectively, the apoptosis rates of the respect ive times were 5.0%, 12.9%, 27.6%. The expression of genes p53 and Bcl-2 was no t influenced, whereas the expression of Bax and Caspase3 had increases time-dep endently after exposure to paclitaxel. The analysis of Annexin-V showed a drama tic dose-dependent increase of apoptosis. Conclusions:Paclitaxel inhibited bladder cancer cells prolifera tion and had more effect on those cells whose grade was lower and doubling time was longer. Paclitaxel could block G_2/M arrest, and induce apoptosis by th e path of Bcl-2/Bax in bladder cancer cell lines.

Objective To know the influence of gastrointestinal decontamination (including gastric lavage and activated charcoal treatment) on prognosis of asymptomatic presentation poisoning patients.Method six hundred and twenty seven asymptomatic presentation poisoning cases through January 1999 to December 2006 were reviewed retrospectively.Duration of ED stay and intubation requiring rate were compared between the intervention group and control group (patients treated only with supportive care),as well as complications associated with gastrointestinal decontamination intervention.Results Statistic analysis reveals no difference between the intervention group and the control group in rate of intubation (6.5 % vs 5.3 %,P=0.51) and emergency care unit admission (28.1% vs 26.6%,P=0.68).Meanwhile duration of ED stay is prolonged profoundly in prevention group [ (11.2?4.7) vs (8.9?5.0),P

Objective To investigate the basic clinical features of non-allergic rhinitis (NAR) in age, sex, incentives, and the effect of treatment with combined intranasal steroids and antihistamines. Methods One hundred consecutive NAR patients were included in this study and the age, gender, predisposing factors and clinical symptoms were analyzed. Combined intranasal steroids and antihistamines used for 8 weeks, the symptoms were recorded before and after treatment with visual analogue scale( VAS) score as the assessment of treatment effects. SPSS 17.0 software was used to analyze the data. Results Ninty-three NAR patients were adults, and the sex ratio was 1 : 1.2( male: female) , and the peak age incidence was between 30 - 39 years old. The main nasal symptoms were sneezing (96 cases) , rhinorrhea (88 cases) , nasal blockage (72 cases) and nasal itching (69 cases). The symptoms of eye and respiratory tract were always accompanied as eye itching (49 cases) , tears ( 32 cases) , congestion ( 22 cases) , swelling ( 13 cases) , cough (21 cases) , suffocation ( 19 cases) , chest compression ( 13 cases) , wheezing ( 10 cases) ; Seventy-nine(79. 0% ) patients could indicate at least one kind of incentives, the temperature change (54 cases) , dust (28 cases) , irritating odor (21 cases) was the main incentive of NAR. Forty-seven patients completed the combined treatment of intranasal steroids and antihistamines, 38 (80.9%) patients were satisfied with the result with all symptoms relieved except wheezing ( P < 0. 05 ) , but36 patients had the NAR returned when they were exposed with the predisposing factors in the coming year; the remaining 9 (19. 1 % ) patients failed the treatment. Conclusions The clinical features of NAR were as follows: adult constituted the main patient population, women were slightly more than man but with no difference between genders; sneezing and nasal discharge were the main clinical symptoms, always more than 1 incentives. The combination of intranasal steroids and antihistamines could control the most of clinical symptoms.

OBJECTIVETo observe the therapeutic effect of continuous blood purification (CBP) combined with hemoperfusion (HP) in children with hemolytic-uremic syndrome (HUS) and to investigate its possible mechanism.

METHODSEight children with HUS received CBP combined with HP on the basis of internal medicine treatment in the acute stage. Before and after treatment, serum levels of interleukin-6 (IL-6), IL-8 and tumor necrosis factor-α (TNF-α) were measured by chemiluminescence method, and levels of blood urea nitrogen (BUN), serum creatinine (SCr), alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatine kinase (CK), creatine kinase MB (CKMB), hemoglobin (Hb), platelet (PLT) and C-reactive protein (CRP) were measured. Eight healthy children undergoing physical examination were used as controls.

RESULTSThe 8 children with HUS all survived after CBP combined with HP and showed improved conditions. They had increased Hb and PLT levels and decreased serum levels of IL-6, IL-8, TNF-α, BUN, SCr, ALT, CK and CRP after treatment (P<0.05).

CONCLUSIONSCBP combined with HP can quickly remove pathogenic factors, continually eliminate inflammatory mediators and toxins, and reverse multiple organ dysfunction, and is one of effective methods for treating HUS in children.

OBJECTIVETo investigate the effect of Bushen Ningxin decoction (BSNXD) on postmenopausal osteoporosis.

METHODSPostmenopausal osteoporosis model of female BALB/c mice were founded and afforded with BSNXD. The experiment was ceased, and the skeleton and blood of mice in each group were collected following 12 weeks of the treatment. Change of osteoblastic organelle in right femur was observed by transmission electron microscope (TEM). Osteoblasts from calvaria of different groups were isolated and cultured by the tissue fragment migrating growth method and the proliferation ratio of osteoblasts in the second passage was examined with thiazolyl blue reagents when cultured for 1 day and 5 days, respectively.

RESULTSTEM showed that the osteoblasts of the animal treated by BSNXD had more cell organelles and developed Golgi complex, whose ability of proliferation(P < 0.05) and anti-apoptosis is stronger than that of OVX group.

CONCLUSIONBSNXD can accelerate the proliferation and inhibit the apoptosis of osteoblasts, the effective concentration of pharmacological serum varies from 10% to 20%.

Background and purpose: Pancreatic intraepithelial neoplasia (PanIN) is thought to be a precursor lesion of infiltrating pancreatic ductal adenocarcinoma. The mutation of the phenotypic impact of K-ras G12D alone, silencing of p53 and p16 could promote this process. The role of Smad4 in this progression was poorly understood. In the present study, we investigated the role of Smad4 in the development of pancreatic tumor, based on PanIN cell line from mice with K-ras G12D mutation in order to investigate the effect of Smad4 silencing on PanIN cells in the development and malignant transformation in nude mice. Methods: Smad4 knock-down PanIN cells (PanIN-S) were established by stable transfeetion with lentiviral-mediated Smad4 RNA interference (RNAi). In xenograft model experiments, BALB/c nude mice were randomly divided into 2 groups (5 mice per group) implanted with PanIN or PanlN-S cells subcutaneously. Two weeks after tumor cells inoculation, tumor volume and weight were estimated. PCNA staining was used to evaluate cell proliferation and CD31 polyclonal antibody was used to assess micro-vessel density (MVD) in tumors. Results: Effect of siRNA of Smad4 gene in PanlN cells was confirmed by RT-PCR and Western blot. Compared with PanlN groups, there was a dramatic increase in tumor volume and weight in PanIN-S groups (P<0.05). Furthermore, immunohistochemical analysis of the harvested tumors suggested that Smad4 silencing was associated with 'increased tumor cell proliferation (PCNA reactivity) and angiogenesis (micro-vessel density, MVD). The percentage of PCNA-positive cells in the PanlN-S groups were significantly increased than PanIN groups (P<0.05). CD31 staining revealed a significant increase in the PanlN-S groups compared to the PanlN groups (P<0.05). Conclusion: Silencing of Smad4 in PanlN cells with endogenous expression of K-ras G12D, enhanced progression to invasive adenocarcinomas. Cell proliferation and vascularization may be its important mechanisms.

Objective To compare and analyze the clinical characteristics in patients with hyperreactive non-allergic rhinitis (HNA R) and allergic rhinitis (AR). Methods A questionnaire survey on AR and HNAR patients between January and August 2009 was conducted. The clinical data of 298 AR patients and 100 HNAR patients were analyzed, including gender, age distribution, seasonal, clinical symptom and induced factors. Results The number of male patients was more than female in AR, while in NAR, the number of female patients was more than male(χ2 =6. 415, P =0. 01). The highest morbidity age in AR was teenagers, aged between 10 - 19 (χ2 = 12. 772, P = 0. 00), while in HNAR, the highest morbidity age was middle-aged and youth, aged between 30-39(χ2 =51. 533, P =0. 00). The main onset seasons in AR was autumn, while there was no seasonal diversity in HNAR. The main allergen in AR was mugwort and ragweed, consistent with the vegetative cover characteristic in Jilin province. The main classification of AR was moderate-severe persistent(χ2 = 123.991, P =0. 00), while the main classification of HNAR was moderate-severe intermittent (χ2 = 97. 420, P = 0. 00) . The clinical symptoms were significantly different between AR and HNAR except rhinocnesmus(all P < 0. 05). There was consistency about non-specificity induced factors in AR and HNAR(all P > 0. 05). Conclusions There were significant differences between AR and HNAR in sex, age, classification and seasons. The severity of clinical symptoms in AR was higher than that in HNAR except sneezing and gasping. There was consistency about induced factors in AR and HNAR.

BACKGROUNDWith a type C3 distal radius fracture it is extremely difficult to maintain the reduction and to restore congruity of the articular surface because the support for the volar and dorsal bone cortex has been lost. An external fixator crossing wrist in combination with Kirschner wire (K-wire) fixation was popularly used by most studies in recent years. But loss of reduction often occurred especially in the volar sides.

METHODSA total of 30 cases of type C3 distal radius fracture were treated by a volar buttress plate combined with a transarticular external fixator and other techniques such as K-wire fixation and bone grafting if necessary. The postoperative volar tilt angles, ulnar inclinations, radial heights, range of motion, grip strength and complications were recorded to assess the therapeutic effects.

RESULTSOf the 30 patients, 27 patients were followed up for 12 - 29 (mean 18) months and all fractures healed in 8 - 13 weeks after surgery (mean 10 weeks). The wrist function was excellent in 8 cases, good in 16 cases and fair in 3 cases according to the Sarmiento scoring system (modified by Stewart).

CONCLUSIONSFor type C3 comminuted fracture with severe volar and dorsal instability, fixation by volar buttress plate combined with transarticular external fixator should be adopted. Dorsal instability could be further stabilized by other techniques such as Kirschner wire fixation, and bone grafting.
