ObjectiveTo determine the impact of lupus flares on maternal and fetal outcomes in pregnant patients with systemic lupus erythematosus(SLE).MethodsData was obtained from 46 pregnancies of 44 pregnant women with SLE.The relationship between lupus flares and pregnant outcomes,and the risk factors for adverse maternal and fetal prognosis were analyzed.T-test,X2 test or Fisher's exact test and Logistic regression were used for statistical analysis.Results① Lupus flares occurred in19(41％)pregnancies(group A) and stable lupus disease was observed in 27(59％) pregnancies(group B) during pregnancy.Compared to pregnancies in patients with stable lupus disease at the conception(n=32),pregnancies in patients with unstable lupus disease at the conception(n=8) had higher lupus flare during pregnancy( 100％ vs 16％,P＜0.05).(②) The common manifestations of lupus flares during pregnancy were lupus nephritis (LN) (11 cases),skin rashes (10 cases),arthritis (7 cases),and the common complication was infection ( 11 cases).(③) The incidence of premature labor,fetal growth retardation (FGR) and fetal loss in group A was 42％,47％ and 26％ respectively,which was significantly higher than that of the group B (7％,15％ and 0 respectively)(P＜0.05).There was no difference in the incidence of preeclampsia,fetal distress and neonatal asphyxia between the two groups ( 16％ vs 7％,16％ vs 19％,5％ vs O,respectively,P＞0.05).The incidence of premature labor and FGR in patients with active LN was higher than that of patients without active LN (55％ vs 11％,64％ vs 17％,respectively,P＜0.05).(④)The binary Logistic regression analysis showed that renal impairment,hypocomplementemia,aPL and serum urea nitrogen level were independent risk factors for premature delivery,FGR,fetal loss and fetal distress.Conclusion(①) Lupus flares during pregnancy increase the incidence of premature labor,FGR and fetal loss.Active LN during pregnancy can increase the incidence of premature labor and FGR.② Renal impairment,hypocomplementemia,aPL and serum urea nitrogen level are associated with adverse fetal outcomes in pregnant patients with SLE.

OBJECTIVETo study the expression of the Trp-p8 protein in the prostate tissue of the PSA "grey zone" with different PSA density of the transition zone (PSADTZ) and explore the value of determining Trp-p8 expression and PSADTZ in the early diagnosis of prostate cancer (PCa).

METHODSThis study involved 30 cases of benign prostatic hyperplasia (BPH) and another 30 cases of PCa with different PSADTZ values. Using a data imaging and analysis system, we determined the expression levels of Trp-p8 in BPH and PCa tissues and analyzed their correlation with PSADTZ.

RESULTSThe expression of Trp-p8 was weak or negative in the BPH but strong in the PCa tissue and even stronger in the PCa tissue with high PSADTZ (F = 34. 05, P < 0.05).

CONCLUSIONThe Trp-p8 protein is expressed differently in BPH and PCa tissues of the PSA " grey zone" and its expression is positively correlated with PSADTZ. Determination of the Trp-p8 expression and PSADTZ contributes to the early diagnosis of prostate cancer.

Osteonecrosis of the femoral head is frequently observed in patients treated with excessive corticosteroids. However, the pathogenesis of corticosteroid-induced osteonecrosis remains unclear. The purpose of this study was to investigate the role of Toll-like receptor 4 (TLR4) signaling pathway in steroid-induced femoral head osteonecrosis in rats. Male Sprague-Dawley rats were injected intramuscularly with 20 mg/kg methylprednisolone (MP) for 8 weeks, twice per week. The animals were sacrificed at 2, 4 and 8 weeks after the last MP injection, respectively, and then allocated to the 2-, 4- and 8-week model groups (n=24 each). Rats in the control group (n=12) were not given any treatment. Histopathological analysis was performed and the concentration of tartrate-resistant acid phosphatase (TRAP) in plasma was determined. The activation of osteoclasts in the femoral head was assessed by TRAP staining. The expression of TLR4, MyD88, TRAF6 and NF-κB p65 that are involved in TLR4 signaling, and MCP-1 production were detected by using real-time PCR (RT-PCR) and Western blotting. The results showed that the osteonecrosis in the femoral head was clearly observed and the concentration of TRAP in the plasma was increased in the model rats. The femoral head tissues in MP-treated rats were positive for TRAP and the intensity of TRAP staining was greater in MP-treated rats than in control rats. As compared with the control group, the mRNA expression of TLR4 signaling-related factors was enhanced significantly at 4 and 8 weeks, and the protein levels of these factors increased significantly with time. It was concluded that MP could induce the femoral head osteonecrosis in rats, which was associated with osteoclast activation via the TLR4 signaling pathway. These findings suggest that TLR4 signaling pathway plays a pivotal role in the pathogenesis of steroid-induced osteonecrosis.

Papillary cystadenoma of the epididymis is a rare benign tumor, accounting for only 4 per cent of all epididymal tumors. Histologically, it can be confused with metastatic renal cell carcinoma. This extremely rare lesion may occur sporadically or as a manifestation of von Hippel-Lindau(VHL) disease. The present paper reported a case of papillary cystadenoma accompanied by testicular atrophy with no signs of VHL syndrome or infertility. To date, no similar case was reported in the literature. The tumor measured 5.0 cm x 4.0 cm x 4.0 cm and was located in the right epididymis. Histopathologic examination of a surgically removed specimen indicated a primary papillary cystadenoma. Histomorphologically, these tumors are characterized by cysts with colloid-like contents and papillary formations of light epithelium. Since metastatic renal cell carcinoma may be histologically similar to papillary cystadenoma, the importance of long-term urologic follow-up for possible presentation of renal cell carcinoma is discussed.

Objective To observe the effects of acupuncture therapy with finger on back-shu point on acid reflux and lower esophageal sphincter pressure (LESP) of the patients with gastroesophageal reflux disease (GERD). Methods Totally 120 patients of GERD were randomly divided into treatment group and control group through random number table method, 60 cases in each group. Patients in the treatment group were treated with the acupuncture therapy with finger on back-shu point, and patients in control group were treated with lansoprazole tablets and dispersible mosapride citrate for two weeks. Total percentage of acid reflux time, the long time acid reflux episodes, and the longest acid reflux time of two groups were observed six months after the treatment. At the same time, the LESP variation of two groups was followed up six months after the treatment. Results The total percentage of acid reflux time, the long time acid reflux episodes, and the longest acid reflux time decreased significantly in all patients after treatment (P<0.01), while the comparison between groups showed no significant difference (P>0.05). After treatment, LESP of two groups was significantly improved (P<0.05) than before treatment. After stopping treatment half a year, the treatment group had obvious difference (P<0.05) compared with before treatment, while the control group had no significant difference (P>0.05). Conclusion The acupuncture therapy with finger on back-shu point can reduce acid reflux, and achieve the goal of treatment of GERD by improving the lower esophageal sphincter pressure. The duration of improving LESP is longer.

Objective： To study the application of DSA in the diagnosis and treatment of ENT diseases. Methods： The diagnostic and therapeutic roles of DSA in ENT patients admitted from November 1995 to December 1999 were retrospectively studied. Results： Therapeutic vascular embolization using DSA was performed in 9/10 patients with severe epistaxis. The treatment was successful in 8/9 patients with a successful rate of 88.89%; embolization of tumor supplying vessels using DSA as a preoperative measure for reducing operative blood loss in 3 patients with nasopharyngeal fibrohemangioma obtained a total success; diagnosis was clarified in 2 patients using DSA. No patients were with severe complications. Conclusion： DSA is not only a safe and effective measure for diagnosis and therapy, but also effective in differential diagnosis of space occupying lesions. Preoperative selective embolization of tumor supplying arteries can reduce operative blood loss.

BACKGROUNDLiving donor kidney transplantation (LKT) has been booming in China. This study aimed to elucidate the renal function of both Chinese donors and recipients after the donation and transplantation.

METHODSOne hundred and forty-one pairs of donors and recipients for LKT were randomly selected and followed up for up to seven years. The donors' and recipients' renal function was recorded before and after operation.

RESULTSThe donors presented a mean age of (43.9 ± 7.5) years at donation. The female contributed 101/141 (71.6%) in all donors, and no effect was shown between genders on healthy donors' renal function. The donors' glomerular filtration rates (GFR) were (119.5 ± 20.4) ml/min, (85.2 ± 17.6) ml/min, (87.2 ± 15.9) ml/min, (82.1 ± 14.6) ml/min and (83.0 ± 13.7) ml/min preoperatively, and for five days, three months, one year and beyond one year after the operation. The donors for the period of 1 - 3 years, 3 - 5 years and more than 5 years after donation showed GFR as (83.9 ± 12.7) ml/min, (83.0 ± 17.6) ml/min, and (80.9 ± 20.8) ml/min, respectively, no statistically significant difference was found. Moreover, no significant clinical changes in blood pressure and proteinuria were found among the donors. In the recipients, delayed graft function (DGF) rate was 6.4%, acute rejection rate was 11.3%, and GFR were (66.5 ± 16.4) ml/min, (73.2 ± 19.6) ml/min and (63.9 ± 18.6) ml/min respectively at three months, one year and beyond one year post-transplantation respectively.

CONCLUSIONThe donors/recipients of LKT in Chinese population experience well-functioning remaining/donor kidneys.

OBJECTIVESTo study the occurrence of different anomalies associated with hypospadias and to instruct relevant treatment in clinical practice.

METHODSThree hundred and forty-one cases of hypospadias were investigated, all treated respectively corresponding to their specific anomalies.

RESULTSThe morbidity of associated anomalies in cases of hypospadias was as high as 21.1%. Most of the anomaly cases were undescended testes and inguinal hernia, and the incidence of associated anomalies was related to the degree of hypospadias.

CONCLUSIONSHypospadias is not just a local dysmorphic problem but rather a local manifestation of a systemic disease. It is necessary to take those associated anomalies as a systemic whole and attach enough importance to their clinical treatment.
