Objective To Investigate the clinical relationship between the interstitial cystitis and female hormone imbalance.Methods A retrospective analysis of 58 cases of IC female patients in our hospital from January 2006 to April 2012.The patients' age ranged from 21 to 76 years,and the average age was 40.2±12.4 years old.The suffering time of disease ranged from 9 to 120 months,and the average duration was 64.3±55.7 months.At the 1st,12th,22th day of the menstrual cycle,the O'Leary-Sant and PUF questionnaires were used to score,in order to analyze the relationship between IC symptoms and the menstrual cycle.The symptoms scores between postmenopausal patients and No menopause patients were compared.At the same time,the medical records and follow-ups were reviewed for all patients.Results 51 cases of IC premenopausal female patients suffered more urinary frequency,urgency,and bladder pain during the menstrual period.The proportion respectively were 54.9 ％ (28/51),60.8％ (31/51).The O'Leary-Sant scores of the 1st day were more significant difference than the12th and the 22th day (P＜0.05),but there was no significant difference between the 12th day and the 22th day (P＞0.05).The PUF scores of the 1st day were significant different than the 12th and the 22th day (P＜0.05),but there was no significant difference between the 12th day and the 22th day (P＞0.05).The average scores of O'Leary-Sant and PUF in 7 postmenopausal patients were statistically significant lower than non-menopausal patients (P＜0.05).The incidence of 58 cases with uterine fibroids,breast hyperplasia,ovarian cysts,endometriosis (48.3％,41.4％,5.2％,13.8％) were higher than the average persons (P=0.001,0.460,0.001,0.048),which were significantly higher than the incidence of the general population (30.0％,40.0％,0.3％,7.0％) excepting breast hyperplasia.Conclusions The symptoms of urinary frequency,urgency,and bladder pain in IC patients were more serious during the menstrual period than the other periods.The symptoms of the non-postmenopausal patients were more serious than the postmenopausal patients.The incidence of IC patients associated with hormone imbalance diseases was higher than the general persons,indicating that the fluctuation of female hormone level was likely to be one cause of IC onset.

Aim To investigate the apoptosis-inducing effects of AgLA2 on lung carcinoma cells SPC-A-1 and its mechanism in vitro.Methods The MTT assay was used to assess the proliferation of SPC-A-1 cells treated with AgLA2 in vitro.Apoptosis-inducing effects was investigated by DNA agarose gel electrophoresis,cell morphology and Elisa.RT-PCR was used to measure the expression of bcl-2 and bax mRNA,and immunocytochemistry was used to measure the expression of bcl-2 and bax protein.Results The IC50 of AgLA2 to SPC-A-1 cells was(3.447?0.436)mg?L-1.Treated with AgLA2,typical nuclear chromatine condensation and fragmentation were observed.The concentration of Caspase-3 in the group treated with AgLA2 was higher than that of the control group.Treated with AgLA2,bcl-2 mRNA,protein expression decreased while bax mRNA,protein expression increased.Conclusions AgLA2 can inhibit proliferation and induce apoptosis of SPC-A-1 cells.Its mechanism of action may be related to changing the ratio of bax/bcl-2 and the set-point of apoptosis,making the apoptosis power hold dominance.

OBJECTIVE To evaluate retrospectively the incidence and treatment of infectious complications within the first 60 days after hematopoietic stem cell transplantation,and to find more efficient anti-infective regimens. METHODS To study the incidence,pathogenic microorganism,prophylaxis,treatments of infectious complications in 150 patients accepted hematopoietic stem cell transplantation from April 1984 to March 1998 in our hospital.The results were analyzed statistically.RESULTS Incidence of infectious complications was 89.3% in all 150 cases.Three patients(2%) died of the fungal infection.The incidence of the infections was 32.5% in patients accepted treatment with imipenem or／and ceftazidine,and 15.7% in other patients without the treatment with imipenem or／and ceftazidine(P＜0.02).CONCLUSIONS The strong antibacterial prophylaxis can′t reduce the incidence of infection,and may increase the chance of fungal infection.

Objective To investigate the incidence of heterotopic ossification in cervical artificial disc replacement in Chinese mainland population by meta-analysis.Methods The related literatures published between 1997 and June 2012 were collected from both English databases,including Pubmed,Ovid,Cochrane library and Embase,and Chinese databases including Chinese Biomedical Literature Database,China National Knowledge Infrastructure,VIP database and Wanfang database.Literatures were selected in strict accordance with the inclusion and exclusion criteria.Studies providing data of prevalence of heterotopic ossification after cervical artificial disc replacement in Chinese mainland population were included.The information of literatures was extracted by excerpts questionnaire,and recorded by two independent researchers.I2 was calculated to test heterogeneity among studies.A random effects model was used if I2 ≥25％.Subgroup analysis was done according to the number of levels of disc replacement,brands of implants and duration of follow-up.Sensitivity analysis was done according to the sample size.The Meta-Analyst software was used for statistical analysis.Results A total of forty studies (1822 cases) were included in this study.The pooled incidence of heterotopic ossification was 7.3％ (95％CI:4.7％ to 11.0％).For single and mixed level disc replacement,the incidence was 11.6％ and 5.8％,respectively.For single and mixed level disc replacement using Bryan disc,the incidence was 13.8％ and 5.4％,respectively,and the total incidence was 7.2％.No matter the single or mixed level disc replacement,the incidence of heterotopic ossification increased with follow-up.Conclusion The incidence of heterotopic ossification in cervical artificial disc replacement is high in Chinese mainland population,while it is lower than in foreigners.However,it is necessary to monitor its long-term incidence due to its increase with follow-up.

Objective To retrospectively evaluate the incidence and treatment of fungous infection compli-cations after hematopoietic stem cell transplantation. Methods The incidence, pathogenic microorganism, prophy-laxis,treatments of infectious complications in 150 patients, who accepted hematopoietic stem cell transplantation from September 1990 to Martch 2000 in our hospital were analyzed. Results The incidence of infectious complica-tions was 89.3% (134/150) in all 150 cases. Three patients (2%) died of the fungal infection. The incidence of the fungal infections was 32.5% (26/80) in patients who accepted treatment with impenem or/and ceftazidine, and 15.7% (11/70) in other patients without the above treatment (P<0.05). 12 fungal infection cases were treated with small-dosage of amphotericin B(10 mg/d) ,with the healing rate was 100%. Conclusion The strong antibac-terial prophylaxis can't reduce the incidence of infection ,but may increase the risk of fungal infection;small-dosage of amphotericin B is a new effective way to treat fungal infection.

Objective To evaluate the clinical outcomes of sacral decompression and lumbopelvic fixation for neurologically impaired patients with sacral fracture-dislocation.Methods From January 2009 to December 2013,32 patients with sacral fracture and spino-pelvic dissociation of Roy-Camille types Ⅱand Ⅲ were treated at our department.They were 21 men and 11 women,with a mean age of 34.3 years.According to Roy-Camille classification,9 patients belonged to type Ⅱand 23 to type Ⅲ;25 patients had S1 fracture-dislocation and 7 S2 fracture-dislocation.After their overall conditions were stabilized,all were treated with open reduction,sacral decompression and lumbopelvic fixation.Pre-and post-operative neurological functions were recorded by Gibbons criteria.We analyzed the correlations between the neurological recovery and (i) the extent of cauda equina deficit and (ii) the continuity of sacral roots,as well as the correlations between the functional recovery of the bladder and bowels and the above two.The reduction and fusion status were evaluated by the Mears and Velyvis radiological criteria;clinical effectiveness was evaluated by Majeed scoring system.Intra-and post-operative complications were all recorded.Results The mean follow-up time for this series was 35 months (from 25 to 47 months).The average Gibbons score improved from 4.0 to 2.7 at the follow-ups.The patients with mild cauda equina deficit or with continuity of sacral roots achieved significantly better neurological recovery than those with severe cauda equina deficit or with discontinuity of sacral roots (P ＜ 0.001).However,the functional recovery of the bladder or bowels was not significantly correlated with the extent of cauda equina deficit or with the continuity of sacral roots.Anatomical reduction was achieved in 26 patients,satisfactory reduction in 5 and unsatisfactory reduction in one,yielding a satisfaction rate of 96.9％.Bony fusion was obtained in 29 patients at 3 months,but not until at 9 months in 2 patients,and still not at 9 months in one who showed no symptoms.The Majeed scoring showed 22 excellent,6 good and 4 moderate cases,giving an excellent to good rate of 87.5％.Two patients developed deep wound infection,3 complained of the pain related to hardware prominence,and one had unilateral rod breakage.Conclusions In treatment of sacral fracture with spino-pelvic dissociation,sacral decompression and lumbopelvic fixation can lead to effective neurological recovery,restoration of lumboscacral stability and alignment,early ambulation and prevention of deformity.Complete neurological recovery is more likely in patients with incomplete cauda equina deficit or with continuity of all sacral roots.

OBJECTIVETo examine the expression level of miR-24 in the plasma of nasopharyngeal carcinoma (NPC) patients and investigate the clinical significance of miR-24 in NPC development.

METHODSBlood samples were from 217 NPC patients admitted in our Department between December, 2007 and June, 2011, with those from 73 patients with chronic purulent otitis media or chronic sinusitis as control. The follow-up data of all the patients were reviewed and the expression of miR-24 in the plasma was examined by qRT-PCR. The correlation of miR-24 expression with clinical staging of NPC was analyzed, and miR-24 levels before and after the treatment were compared.

RESULTSCompared with the control group, the NPC patients showed significantly up-regulated level of miR-24 in the plasma (P<0.001). Plasma miR-24 level differed significantly among patients with different T stages (P=0.007) and was negatively correlated with the N stages (P=0.028) and plasma EBV-DNA (P=0.048). The expression levels of miR-24 were significantly reduced after treatment in the NPC patients and were significantly lowered in patients without relapse or metastasis (P=0.001).

CONCLUSIONPlasma miR-24 may serve as a novel molecular biomarker for early diagnosis and prognosis of NPC.
