ObjectiveTo investigate the genomic and non-genomic effects of 17β-estradiol on gallbladder smooth muscle strips of guinea pig and their possible mechanism. MethodsAfter ovariectomized operation (OVX) and subcutaneous injection of 17β-estradiol, the contents of serum estradiol and cholecystokinin-octopeptide (CCK-8) of the sham operation group (Sham) guinea pigs, the OVX group, the OVX and subcutaneous injection 17β-estradiol for 1 day (OVX+E2, 1 d), 3 days (OVX+E2, 3 d) and 7 days (OVX+E2, 7 d) were detected by EILSA respectively. The effects of CCK-8/Ach on constriction of gallbladder muscle strip were observed among various groups by using tension transducer, and the acute effects of 17β-estradiol on guinea pig gallbladder smooth muscle strips were observed to probe its possible mechanism. ResultsCompared with the Sham group, the serum contents of estradiol and CCK-8 decreased in OVX group (P＜ 0. 05) whereas the sensitivity of OVX guinea pigs gallbladder muscle strips to CCK-8/Ach increased (P＜0.05). With the extension of the subcutaneous injection 17β-estradiol time (for 1, 3, 7 days), both the serum estradiol and CCK level increased (P＜ 0.05) while the guinea pig gallbladder strips sensitivity to CCK-8/Ach decreased (P＜0.05).17β-estradiol at concentration ranging from 10 9 to 10-7 mol/L have no effect on the guinea pig gallbladder strips contraction (P＞0.05), but at concentration of 10-6 and 10 5 mol/L, it can inhibit the gallbladder contraction (P＜0.05). The blocking agents, such as nimodipine, atropine, devazepide, ICI 182,780 and Y-27632, can block the inhibited effects of 17β-estradiol. ConclusionThe 17β-estradiol can affect the gallbladder motility, both by genomic and non-genomic pathway.

Objective To study the body composition of public security staffs and to prevent sub-health condition positively. Methods Body compositions of 771 public security staffs were measured and analyzed with bioelectrical impedance analytic process (BIA). Results The male public security staffs had obviously lower body fat percentage (P< 0.01) but higher body mass index and obesity (P<0.05) than female public security staffs. Both male and female public security staffs fad the highest content of fat in the lower limbs. The body part ranked the second place, followed by the upper limbs. Measured by body-fat percentage(BF%), the obesity rate of the male and female staffs was 10.08% and 45.59% respectively. Measured by body mass index (BMI), the hypergravity rate of the male and female staffs was 44.09% and 20.59% respectively; and the obesity rate of the male and female staffs was 8.35% and 0.74% respectively. Measured by obesity degree (OBD), the hypergravity rate of the male and female staffs was 21.73% and 4.41% respectively; and the obesity rate of the male and female staffs was 11.65% and 1.47% respectively. Conclusion Public security staffs should pay attention to their over-weight and hyper-fat level. Proper dict and body exercise are needed.

Objective To discuss the Clinical character of pulmonary tuberculosis combined malignant lymphoma and its Pathogenesis,and to review the literature.Methods Eighteen cases of pulmonary tuberculosis combined malignant lymphoma from 1996 to 2003 were retrospectively analyzed by its clinical manifestations,X-ray features,diagnosis and treatments.Results 18 cases were all infiltrative pulmonary tuberculosis,13 them were calcification focals,5 were active pulmonary tuberculosis;5 of all were Hodgkin’s lymphomas,13 of all were non-Hodgkin′s lymphomas.16 cases were lymphomas after tuberculosis,2 cases tuberculosis after lymphomas,none were co-existent malignant lymphoma and tuberculosis.Tuberculosis may precede or complicate a lymphomatous process during the development of both diseases,This might is linked to immune deficiency and chronic inflammation;Lymphomas might cause pulmonary tuberculosis,it might cause the immune turbulence of an individual,Pulmonary tuberculosis infection occurring during or after the radiotherapy and chemotherapy of lymphoma.Conclusions It may pulmonary tuberculosis combined malignant lymphoma in the patients in the endemic areas of tuberculosis,Appropriate invasive biopsy procedures are necessary for early diagnosis.

Objective To explore the early diagnostic significance of anti-cyclic citrullinated peptide(CCP) antibody and hidden rheumatoid factor immunoglobulin M(HRF-IgM) detected by ELISA in patients with juvenile rheumatoid arthritis(JRA). Methods The synthesized CCP was used as the antigen to detect anti-CCP antibody. Anti-CCP antibody and HRF-IgM were detected dynamically in 27 patients with early diagnosed JRA and their specificity and sensitivity were determined for early diagnosed JRA by calculating the positive predicting value (PPV) and negative predicting value (NPV). Results The total positive rate of anti-CCP antibody and HRF-IgM were 58.5 % and 65.0 % respectively in patients with JRA. The sensitivity of HRF-IgM was more predominant than that of anti-CCP antibody. There was a positive correlation between the positive rate of antibodies and the subtype of JRA. The specificity of anti-CCP antibody for predicting early JRA was superior to that of HRF-IgM. When using these two tests in combination, the PPV predicting rate of early JRA was 93.7 % . Conclusions Both anti-CCP antibody and HRF-IgM are elevated in patients with JRA, which show positive correlations with the subtype of the disease. The specificity of anti-CCP antibody testing is considerably higher for diagnosing early JRA, and when it was used together with HRF-IgM testing, the PPV for JRA can be raised further.

Objective To investigate the prevalence of nodular gastritis,duodenal ulcer before and after eradicative treatment of helicobactor pylori(Hp) infection in children with gastroscopy.Methods This was a retrospective analysis of 1 275 children,age ranging 1 to 16 years old,collected from our hospital in recent 10 years,detecting rates of before eradicative treatment and after eradicative treatment were analyzed.Gastroscopes were analyzed with regard to a possible association with the infection.Results The detecting rate(11.89%) of duodenal ulcer after eradicative treatment was lower than that(17%) before eradicative treatment(P

0.05).There was significant difference of curative effect before and after treatment of children with RAP(?2=6.74,P

Objective To analyze the clinical features of urothelial carcinoma in renal allograft re- cipients and to investigate its diagnosis and treatment.Methods A retrospective study was undertaken on 1293 renal allograft recipients in our center between 1998 and 2003.Of them ,21 cases(72.4% )had urothe- lial carcinoma(4 males and 17 females).All the cases had not had tumor before transplantation.In 17 cases the protopathy was chronic interstitial nephritis(CIN).The mean interval between tumorigenesis and trans- plantation was 26 months(range,6-62 months).Of the 21 cases,6 had bladder transitional cell carcinoma (TCC);6 had unilateral pelvic or ureter TCC;8 had unilateral pelvic or ureter and bladder TCC;1 had bilat- eral pelvic and ureter TCC.In 10 cases,the ipsilateral upper urinary tract of the graft was involved;and in 4 cases,the contralateral upper urinary tract was involved.Painless gross hematuria and iterative urinary tract infection were the cardinal symptoms.Surgical treatment was performed in 19 cases.Postoperatively,all the cases received immunosuppressants at one third reduction dose in combination with intravesical instillation chemotherapy.Results Two cases receiving palliative treatment died 5 and 8 months after diagnosis.The other 19 cases were followed for 2-5 years.Of them,13 cases had tumor recurrence.The recurrence sites were bladder and the contralateral upper urinary tract.All the cases had no acute rejection at reduced dose of immunosuppressants,and all had normal renal function except for 2 cases,who underwent removal of the graft and had dialysis again.Conclusions Renal allograft recipients whose protopathy is CIN and female recipients have the risk of urothelial carcinoma after renal transplantation.Urothelial carcinoma occurs more often in ipsilateral upper urinary tract of the graft than in contralateral upper urinary tract.Considering the high possibility of bilateral upper urinary tract involvement by TCC,prophylactic bilateral nephroureterectomy with bladder cuff excision should be considered in renal allograft recipients who have involvement of contra- lateral upper urinary tract of the graft.

Objective To study the effect of antiapoptosis factors PED/PEA-15 and XIAP on prostate cancer cells(PC-3)apoptosis.Methods The expressions of XIAP and PED/PEA-15 in prostate cancer cells(PC-3)were respectively assayed using the RT-PCR technique.XIAP and PED/ PEA-15 specific siRNA vectors were designed and constructed and then were transiently cotransfected into PC-3 cells under induction of liposome.The effects of siRNA vectors on PED/PEA-15 and XIAP transcription were assayed by RT-PCR technique,and the effect of XIAP and PED/PEA-15 on cancer cell apoptosis were determined by flow cytometry and microscope observation.Results PED/PEA- 15 and XIAP were both highly expressed in PC-3 cells.Enzyme digestion analysis and DNA sequencing confirmed that the PED/PEA-15 and XIAP-specific siRNA expression vectors were constructed successfully.The designed siRNA sequences of PED/PEA-15 and XIAP could specifically inhibit their transcription.The PC-3 cells which were cotransfected with PED/PEA-15 and XIAP- specific siRNA vectors were more sensitive to doxorubicin.The apoptosis rate of cotransfected cells was significantly increased.Conclusions PED/PEA-15 and XIAP might be involved in the development of prostate cancer.

BACKGROUNDMalignant tumor is the most common complication occurred in transplant recipients. It is widely recognized that immunosuppressive treatments increase the risk of cancer in transplant recipients. The efficacy and safety of rapamycin (RPM) in combination with low-dose calcineurin inhibitor (CNI) in treating 15 renal allograft recipients which developed urothelial carcinoma were observed.

METHODSImmunosuppressive regimen in all recipients was altered with rapamycin to replace mycophenolate mofetil (MMF) or azathioprine (Aza). The initial loading dosage was 2 mg/d, and the next dosage was 1 mg/d. The dosage of rapamycin was carefully adjusted according to the blood drug level and concentration of the drug was maintained at 4 - 6 microg/L. In all the 15 patients, the calcineurin inhibitor was reduced down to one third of the original dosage after the rapamycin blood concentration became stable. Surgical treatment and intravesical instillation chemotherapy were carried out in all patients. Recurrence of the tumor was monitored throughout the study. Post-transplant renal function and side effects were also closely monitored.

RESULTSAmong the 15 patients, 9 had no tumor recurrence in 2 years, 2 had tumor recurrences twice, and 4 had once. There was no acute rejection observed during RPM treatment. Post-transplant renal function in 11 patients was improved, with a decreased creatinine level. Hyperlipoidemia and thrombocytopenia were the most frequent adverse events which responded well to corresponding treatments.

CONCLUSIONAmong the renal allograft recipients with urothelial carcinoma, combination of rapamycin and low dose calcineurin inhibitor treatment is effective and safe.
