Objective To explore the clinic value of blood loss during and after cesarean section in women with scarred uterus. Methods From July 2007 to December 2008, thirty-six women with scarred uterus received weighing methods to evaluate the actual blood loss during and after cesarean section in Yuhuangding hospital, while 98 cases without pregnant complications were chosen as control. Results In women with scarred uterus, the blood loss during operation Was (372.4 ± 180.0) ml, and the total amount after 2 hours and 24 hours were (444.7± 228.2) ml and (527.4 ±251.6) ml respectively, which were higher than corresponding values in control group (P < 0. 05). The incidence of postpartum hemorrhage in scarred uterus was 47.2%, higher than that in control group (P < 0. 05). There were no significant differences between two groups in the tests of hemoglobin and coagulation functions (P > 0. 05). Conclusions Scarred uterus may be one of the important reasons which lead to postpartum hemorrhage. The clinical treatment of pregnant women with scarred uterus should focus on the prevention of blood loss during the cesarean section.

Objective To explore the possible association of oxidative stress reaction with the mRNA expression of podocin in rats with adriarnycin(ADR)-induced nephrotic syndrome.Methods mRNA expression of podocin in renal cortex were investigated by in situ hybridization staining and semi-quantitative RT-PCR in ADR-induced nephrotic rats,the level of malondialdehyde(MDA), superoxide dismutase(SOD)and total antioxidative capacity(T-AOC) in renal cortex were measured, then the relationship between them was evaluated.Results In ADR rats, MDA increased at d7 and reached a significant higher level at d14 and d21;SOD decreased at d14 and persisted to d21; T-AOC decreased at d21.The podocin mRNA mostly expressed in cytoplasm of glomerular cells. Both the number and the intensity of positive cells increased notably as time progressed in ADR rats.The level of podocin mRNA expression showed no obvious changes at d7, while prominently increased at d14 and pesisted to d21 in ADR rats.There was significant correlativity between the mRNA expression of podocin and the level of MDA,SOD,T-AOC.Conclusion The mRNA expression of podocin is correlated with oxidative stress reaction in rats with ADR-induced nephrotic syndrome.

Objective To investigate the association between the target organ damage and morning blood pres- sure surge(MBPS) in the elderly hypertensives.Methods Three hundred thirty-two patients submitted to 24 h ambulatory blood pressure monitoring were categorized as with MBPS (n=173),and non-MBPS(n=149).Total cholesterol,body mass index(BMI),left ventricular mass index (LVMI),carotid endothelial medium thickness (CCA-IMT and ICA-IMT) and corrected QT dispersion(QTcd) were determined.Results 24 h,day and night mean systolic blood pressure in MBPS group were significantly higher than that in the non-MBPS group(P

Objective To evaluate the diagnosis and treatment of urinary tract endometriosis.Methods Retrospective review of 10 female cases of urinary tract endometriosis was carried out. All cases age was from 28-49, and the average age was 39-year-old. The course of this disease was from 6 months to 3 years. Four of 10 cases were bladder endometriosis. The clinical presentations included the urgency, frequency, pain at micturition and lower abdomen pain during menstruation, gross hematuria coinciding with menstruation 1 case. B-ultrasound and CT showed the mass of bladder from 2. 0 -3.5 cm but were not specific. Four of 6 cases ureteral endometriosis were the left side and 2 cases were the right side. This clinical presentation included non-specific flank or abdomenal discomfort in 4 cases, intermittent gross hematuria in 1 case and 1 case renal hydronephrosis was found incidentally by B-ultrasound. B-ultrasound indicated unilateral upper urinary tract dilation and hydrops in all cases,with pyelic separation from 2.0-4.5 cm and ureteral separation from 1-2 cm. CT indicated stenosis of the lower ureter in 5 cases, ureter tumor in 1 case. Results All cases were treated surgically.Partial cystectomy were performed in 4 cases of bladder endometriosis, of which, 1 case bilateral oophorectomy and hysterectomy. Five cases were performed ureteral segmental resection, of which, 3 ureterocystostomy and 2 terminoterminal anastomosis. 1 case was performed radical nephrectomy and ureterectomy. Postoperative pathological findings confirmed the diagnosis of endometriosis. Postoperative oral hormone therapy was given to 9 cases for 6-12 months. All cases were followed for 12-60months. 2 cases ureteral endometriosis had recurrent hydronephrosis in 18-24 months. The 2 cases received ureteral stent and cured by oral hormone therapy or goserelin subcutaneous injection for 3 months. Conclusions Urinary tract endometriosis usually shows non-specific symptoms. The diagnosis can be missed on both clinical examination and preoperative work-up. Surgical treatment is effective and adjuvant hormone therapy is often recommended to prevent the recurrence.

OBJECTIVE To discuss a highly effective method to immobilize probe on the surfaces of piezoelectric DNA sensors.METHODS Pseudomonas aeruginosa probe was immobilized on the gold surface of gene sensor(array) with routine self-assembly method(SAM)(non-reduction method) and SAM with deoxidized probe((reduction) method),respectively.The changes in frequency and time-cost were compared in reactions with(different) concentrations of probe.RESULTS Reduction method had the advantage of more probe immobilization;less time consumed in testing and higher changes in frequency during the reaction than non-reduction method.CONCLUSIONS Reduction method has a better ability to immobilize probe on the surfaces of piezoelectric DNA sensors.

Objective To investigate the therapeutic efficacy of castration with 125I brachtherapy in middle and late stage prostate cancer. Methods Sixty-six patients with prostate cancer from 2004 to 2009 were analyzed, 40 were at clinical stage C and 26 were at clinical stage D, 42 had a pathologic grade G2 and 24 had a pathologic grade G3. The first endocrinal therapy used was total androgen blockade (chemical castration and anti-androgen drugs). The therapeutic time was three months before bilateral orchidectomy and brachtherapy. A 3D radiotherapy planning system was used for brachtherapy with transrectal ultrasound-guided radioactive 125I seed uniform implantation. Follow-up endocrinal therapy was decided according to a monthly check of serum PSA (prostate specific antigen) levels. After six months, serum PSA, IPSS and volume of the prostate before and after treatment were compared. Results The operations were completed successfully in all cases. The mean number of 125I seeds implanted was 55. The mean follow-up was 10 to 62 months, with an average of 49 months. Serum PSA, IPSS and the volume of the prostate was reduced significantly six months after operation (P<0.05). Conclusions Castration with 125I brachtherapy is an effective approach in combination therapy for treating middle and late stage prostate cancer.

Objective To investigate the level and value of serum uric acid (UA) in patients with multiple system atrophy (MSA).Methods One hundred and one MSA patients were selected as the MSA group and 101 age and sex-matched healthy controls as control group.The UA concentrations and other biochemical indexes were measured by an enzymatic method and carefully analyzed.By comparing the UA concentrations for different genders, subtypes, and different levels of certainty of the MSA group with their counterparts in the control group, we obtained the differences between these two groups and also discussed possible reasons and factors.Results The serum UA levels of MSA patients ((283.74 ± 87.76) μmol/L) were significantly lower than the controls ((317.86 ± 76.95) μmol/L;t =-2.94, P ＜ 0.05).In addition, when the male and female groups were investigated separately, the decrease of serum UA was more significant in the male group compared to the female group (t =-3.88, P ＜ 0.01).Furthermore, by comparing different subtypes of the MSA patients with the control group, we found that the serum UA levels in both P-type or C-type MSA patients were significantly lower than in controls (t =2.92, 2.02;all P ＜ 0.05).By comparing different levels of MSA with the control group, we obtained that UA levels in both probable MSA patients and possible MSA patients were significantly lower than in controls (t =3.13, 2.09;all P ＜ 0.05).By adjusting for the confounding factors, such as age, alanine aminotransferase, aspartate aminotransferase, urea nitrogen, creatinine, high density lipoprotein-cholesterol and low density lipoprotein-cholesterol, the multiple Logistic regression analysis showed that the numbers of MSA patients in the lowest level UA group (UA ＜ 263.0 μmol/L) were higher than the high level UA group (UA ＞ 370.5 μmol/L), though the difference did not reach statistical significance (P ＞ 0.05).Nevertheless, the numbers of male MSA patients in the lowest level and the lower level UA groups (UA =263.0-309.0 μmol/L) were 11.5 and 10.8 times that in the high level UA group (P =0.001, P =0.003).No obviously linear relation between the level of UA and disease progression was found.Conclusions The level of serum UA is significantly decreased in MSA patients, especially in the male patients.The UA, as an antioxidant, may be beneficial to the neurodegenerative diseases.

Objective To study the antitumor effect of toremifene on MCF7 cell lines,and investigate the role of mitogen-activated protein kinase pathway. Methods Inhibitory effect of toremifene alone or combined with MEK inhibitor PD98059 on MCF7 cells was measured by SRB test,and that on phosphorylated ERK was detected by Western blotting.Results Toremifene exhibited a concentration-dependent inhibitory effect on the activity of MCF7 cells.Phosphorylated ERK was significantly inhibited by 5,10 and 20 mmol/L toremifene.Combined with PD98059,toremifene had a significantly enhanced cytotoxity effect,which exceeded that of application alone. Conclusion Mitogen-activated protein kinase pathway may play an important role in the antitumor effect of toremifene which is independent of estrogens.Combined with PD98059,the antitumor effect of toremifene can be reinforced,indicating a synergistic effect of these two drugs.
