Objective To explore the value of pneumatic lithotripsy under ureteroscope in the management of ureteral calculus . Methods The clinical data of 360 cases of ureteral stones treated ureteroscopically by pneumatic lithotripsy were retrospectively analyzed. Results Stones were successfully fragmented on one session in 85% of the cases (306/360). Complications were observed in 2 5% of the cases (9/360), including 6 cases of ureteral perforation and 3 cases of urinary infection. Conclusions Pneumatic lithotripsy under ureteroscope is safe, effective and minimally invasive.

To analysis the reason of the arguments of “Sexual hallucinations” or “Sexual harassment”between clinicians and patients,and find out how to prevent its happening.Methods:Base on clinical case about patients complaints that clinicians sexually assault,review and analysis the prtinent literatures.Results:Sexual hallucinations is a complication following anesthesia with psychotropic drugs,it 's easy to be misunderstand as Sexual harassment and result in allegations of sexual misconduct between patient and clinician.Conclusion:Clinicians need to be aware that sexual hallucinations to occur during sedation or after anesthesia,to protect themselves against the accusations of sexual harassment,the practitioner should never be unchaperoned with a patient of the opposite sex during sedation or anesthesia.

Objective:To study the effects of human CBS(Cord Blood Serum) on hematopoietic cells culture in vitro.Methods:CBS and/or different combinations of cytokines were added to the culture system derived from human bone marrow mononuclear cells.Colony forming capacity of colony forming unit-granulocyte/ monocyte (CFU-GM)?colony forming unit-granulocyte/ erythrocyte/ megakaryocyte/ monocyte (CFU-GEMM)?cobble-stone area forming cells (CAFC)?long-term culture initiating cells (LTC-IC) were observed.Results:CBS had certain cytokine-like stimulating activity that could promote the proliferation and differentiation of hematopoietic cells of bone marrow in vitro. By comparison with cytokines, its GM-CSF-like activity was equal to 65.6 ?g/L rhGM-CSF, and its IL-3-like activity was equal to 2.9 ?g/L rhIL-3.Conclusion:CBS contains stimulating activities for proliferating and differentiating of hematopoietic cells. CBS alone can maintain hematopoietic cells culture in vitro. This study showed the prospect of clinical application of CBS.

ObjectiveTo evaluate the efficacy of intravenous and intra-arterial thrombolysis with urokinase for acute cerebral infarction.Methods Fifty patients with acute cerebral infarction occurred within 6 hours were divided into two groups by random digits table method with 25 cases each:intravenous and intra-arterial thrombolysis group and intravenous thrombolysis group.The patients in intravenous and intra-arterial thrombolysis group were given 200 000 U urokinase by intravenous infusion for 30 minutes immediately after being hospitalized,and arterial thrombolysis was prepared at the same time.With cerebrovascular angiography,the thrombolytic therapy was carried out in the target vessel blocking points through micro-catheter.Urokinase dissolved in 0.9％ sodium chloride was infused at the rate of 10 000 U per minute,the total volume would not be more than 1 000 000 U.The patients in intravenous thrombolysis group were given 1 000 000 U urokinase in 100 ml 0.9％ sodium chloride by intravenous infusion within 60 minutes.The clinical efficacy after thrombolysis was assessed according to the National Institutes of Health stroke scale (NIHSS) score,the quality of life was judged by Barthel index (BI) score and the prognosis was evaluated by modified Rankin scale (mRS) score of 90 days after thrombolysis.ResultsThere was no significant difference between two groups before thrombolysis according to the NIHSS score (P ＞ 0.05).After thrombolysis,NIHSS scores in two groups showed a downward trend,but they were obviously lower in intravenous and intra-arterial thrombolysis group after 24 h,7 d and 14 d than those in intravenous thrombolysis group [(8.97±4.56) scores vs.(11.01±3.65) scores,(6.88±2.31) scores vs.(8.34±3.05) scores,( 4.06±3.02 ) scores vs.( 6.73±2.15 ) scores ] ( P ＜ 0.05 or ＜ 0.01 ).BI scores before thrombolysis between two groups had no significant difference(P ＞0.05),while BI score of 90 days after thrombolysis in intravenous and intra-arterial thrombolysis group [(79.55±19.64) scores] was higher than that in intravenous thrombolysis group [(69.31±21.35) scores](P=0.0162).The rate of mRS score 0-2 (good efficscy) in intravenous and intra-arterial thrombolysis group [72.0％(18/25) ] was obviously higher than that in intravenous thrombolysis group [ 52.0％ ( 13/25 ) ] (P =0.0198 ).ConclusionsIt is significantly effective to treat acute cerebral infarction by superselective intravenous and intra-arterial thrombolysis.Therefore,it is supposed to be an optimal option for treating acute cerebral infarction in the future.

Objective To analyze the practicality of current diagnostic criteria of invasive fungal infection (IFI) in patients with hematologic diseases/malignant tumors,so as to enhance the recognition of characteristics of pulmonary IFI after allogeneic hematopoietic stem cell transplantation (allo-HSCT).Methods The clinical features of 51 cases with IFI after allo-HSCT were analyzed retrospectively.Results Pulmonary IFI accounted for 42.1％ (51/121) of the whole infectious pneumonia diagnosed among the patients admitted during the study.One (2.0％) case was proven diagnosis ; 24 (47.1％) were probable diagnosis and 26(51.0％) were possible diagnosis.The using of immuno-suppressors and corticosteroids,and the presence of graft-versus-host disease (GVHD) were the main host factors.The patients with two or more host factors simultaneously accounted for 66.7％ (34/51) of all pulmonary IFI patients.Totally 94.1％ (48/51) of the patients with pulmonary IFI presented nodules and/or patches as the main features in high resolution computed tomography (HRCT) scanning.The positive rates of fungal antigen detection were 58.6％ for G test and 33.3％ for GM test,which were relatively high.Twenty patients (39.2％) showed decrease of arterial partial pressure of oxygen and hypoxia in blood-gas analysis.Conclusions For the diagnosis of pulmonary IFI post allo-HSCT,the administration of immuno-suppressors and corticosteroids,and the presence of GVHD were the main host factors.Nodules and/or patches were the main features in HRCT image.Fungus antigen detection is the main tool to support clinical diagnosis.

Objective To investigate the possibility of anti-liver fibrosis of 13-estradiol nanoparticle prepared by interfacial polymeri-zation method with butylcyanoacylate as carrier material (E2-PBCA-NP) and its effect on the expression of transforming growth factor β1 and connective tissue growth factor in pig serum induced animal fibrotic model. Methods Male Sprague-Dawley (SD) rats were random divided into five groups. Except normal control group, other four groups were all given intraperitoneal injection with pig serum. Therapeutic drugs were administered to rats from the ninth week after injection of pig serum. All rats were killed at the end of the twelfth week. Several experi-ments were done as below, the tissues of liver were observed by Masson staining, and the mRNA of TGF-β1 and CTGF of liver samples were detected by RT-PCR. Meanwhile, the expression of TGF-β1 and CTGF protein were detected by immunohistochemistry. Results It showed that both E2 and E2-PBCA-NP treatment groups had lower stage of liver fibrosis, according to the observation of pathology by Masson staining (P < 0.05). The anti-liver fibrosis effect of E2-PBCA-NP treatment group was better than that of E2 treatment group (P < 0.05). The mRNA and protein level of TGF-β1 and CTGF were markedly reduced by E2 and E2-PBCA-NP treatment, compared with liver fibrotic model groups (P <0.01). There was no statistical difference between E2-PBCA-NP and E2 treatment (P >0. 05), while no significant change was observed in blank nano -particle group (P > 0.05). Conclusion Both E2-PBCA-NP and E2 had anti-liver fibrosis activity. E2-PB-CA-NP has stronger anti - liver fibrosis activity than E2, which could be resulted from the inhibition of TGF-β1 and CTGF expression.

Objective To investigate the expression of CD24 and FAK in the invasive breast ductal carcinoma tissues and their clin-ical significance. Methods Tissues were obtained from 86 patients with breast carcinoma and 30 non-cancer specimens. The expression of CD24 and FAK was detected by immunohistochemical technique (ElivisionTMPlus) and their correlation with tumor clinicopathological char-acters was analyzed. Results The positive rate of CD24 and FAK expression in 86 cases of breast carcinoma was 87.2% (75/86) and 72.1% (62/86) respectively, which was significantly different from that in control group(P<0.01). Expression of CD24 was significantly correlated with axillary lymph node metastasis(P<0.01). Expression of FAK was correlated with histopathologic grade, axillary lymph node metastasis and clinical stage (P<0.05). There was a positive correlation between the expressions of CD24 and FAK in breast carci-noma tissues (rs = 0.222, P < 0.05). Conclusion Expression of CD24 and FAK are closely correlated with the development of breast carcinoma and there is a markedly positive correlation between CD24 and FAK expression. These indexes can be helpful in understanding the biological behaviors and predicting the prognosis of breast carcinoma.

Objective To investigate the expression of CD24 and Ki67 in the invasive breast ductal car-cinoma tissues, so as to assess the role of CD24 protein in the carcinogenesis and progression of breast canc-er. Methods The expression of CD24 and Ki67, Bcl-2 was examined by immunohistochemically in 86 breast cancer specimens and 30 non-cancer specimens ( ElivisionTM Plus). The relationship between CD24 expression and Ki67, Bcl-2, patient age, tumor size, histopathologic grade, axillary lymphnode metastasis, and clinical stage of breast cancer was analyzed. Results In 86 eases of invasive breast ductal carcinoma, the positive incidences of CD24 was 87.2% (75/86), which distinguished apparently from those of the con-trol group( P <0.01 ). In breast carcinoma tissues, the expression of CD24 was positively related to axillary lymphnode metastasis(P <0.01 ), but was not related to patients age,tumor size, histopathologic grade and clinical stage(P>0.05). CD24 expression was positively related to Ki67 (P<0.01 ) and negatively relat-ed to Bcl-2(P>0.05). Conclusion CD24 expression was related to the proliferation, invasion and me-tastasis of breast cancer cells and it can serve as an important marker for predicting biological behavior and prognosis of tumors.
