ABSTRACT:Objective To investigate CA125 and ALDH1 levels in diagnosis and postoperative follow‐up of endometriosis (EMs) .Methods Serum CA125 and ALDH1 levels were tested by enzyme‐linked immunosorbent assay (ELISA) in 105 patients with EMs and 100 healthy subjects who came to our hospital between January 2011 and June 2013 .Results The preoperative serum CA125 and ALDH1 levels of EMs patients were significantly higher than those in the control group ( P<0 .05) .Serum ALDH1 levels in stages I and II of EMs were significantly higher than those in the control group (P<0 .05) ,but there was no difference in serum CA125 level between the two groups ( P>0 .05) .Taking CA125≥35 U/mL and ALDH1≥2 .0 pg/mL as the boundary values ,the specificity , sensitivity ,positive predictive value and negative predictive value of serum CA 125 combined with ALDH1 for diagnosis of EMs were 87 .1% ,91 .6% ,84 .6% and 89 .3% ,respectively .One month after operation ,serum CA125 and ALDH1 levels of EMs patients were decreased significantly (P<0 .05) ,but they were still higher than those in the control group ( P<0 .05) .Six months after operation ,their serum CA125 and ALDH1 levels did not differ from those in the control group (P>0 .05) .Relapse occurred in 1 patient 1 year after treatment and in 6 patients 2 years after treatment ;all these patients had a higher serum ALDH1 level than the control group ,but only 2 of them had a higher serum CA125 level .Conclusion The combined detection of serum CA125 and ALDH1 has a higher sensitivity in diagnosis of EMs .Serum ALDH1 level increases in stages Ⅰ and Ⅱ and recurrent patients and can become a better serum marker for early diagnosis and detection of the recurrence of EMs in patients .

Objective To study the possible protective mechanisms of Anisodamine against liver injury induced by hemorrhage shock(HS). Methods In this study, we established animal models induced by HS and endotoxin, observed the expressions of NF-?B mRNA and heat shock protein 70(HSP 70) mRNA by In-situ hybridization (ISH) in liver kupffercells(KC) and studied the pathologic changes of the liver tissue by microscope. Results After stimulus of HS and injection of endotoxin, the mRNA expressions of HSP70 and NF-?B in KC were (0.1565?0.0260) and (0.1659?0.0103),respectively, and significantly higher than those in the control group (0.0328?0.0201; 0.0256?0.0043)(P

ObjectiveTo explore the renal functions of vasopressin-deficient Brattleboro(BB) rats by using different concentrated Gadolinium-diethylenetetramine pentaacetic acid(Gd-DTPA) dynamic enhanced magnetic resonance imaging(MRI).MethodsThe study included 14 BB rats(male rats of 3 month-old) and 14 normal male Wistar rats used as control group.Dynamic MRI was performed by using either a low dosage(0.05 mmol/kg) or a high dosage of Gd-DTPA(0.5 mmol/kg).Data of 0-60 min renal cortex,medulla and pelvic were obtained after using contrast medium.MRI of kidneys at different time was analyzed and the mean relative signal intensity(RSI) was measured.Then the RSI curves of different groups were marked.Data of each group were caculated separately by SPSS 11.0 software.ResultsThe findings demonstrated that RSI curves of the vasopressin-deficient kidneys showed different patterns as compared with those of the control group(P

To study the influence of foreign plasmid DNA on spleen metabolism in immune-stimulated mice via the gastrointestinal tract. Mice were oral administered by pipette with 200?g of plasmid pcDNA3 and spleen were isolated at 4h and 18h after oral administration. Total RNA were extracted from spleen and spleen gene expression profile of Balb/c mice was analyzed by using Affymetrix oligonucleotide genechip after oral plasmid pcDNA3 administration. Functional cluster analysis was conducted by Genmapp and MAPPFinder software. By functional cluster analyzing the genes which were up-regulated more than twofolds, Genmapp results showed that plenty of metabolic pathway were induced in spleen after oral administration of plasmid pcDNA3. These metabolic process included purine metabolism, pyrimidine metabolism, protein synthesis, cholesterol synthesis, fatty acid synthesis, Glycolysis, TCA cycle and mitochondria oxidative phosphorylation pathway. The similar results also took place at 18h after oral administration. The result indicated that foreign plasmid DNA can modulate metabolism process in spleen of mice via the gastrointestinal tract, and may help understand the mechanism of action of foreign plasmid DNA uptaked via the gastrointestinal tract.

AIM:To report the safty and efficiency of intravitreal injection of bevacizumab (Avastin) in patients with macular edema (ME) due to branch retinal vein occlusion (BRVO).METHODS: A consecutive series of patients with ME due to BRVO who were treated with intravitreal bevacizumab injection (2.5g/0.1L) were retrospectively studied. Patients underwent complete ophthalmoscopic examination, including Snellen visual acuity testing, optical coherence tomography (OCT) imaging, and/or flurescence angiographic testing at baseline and follow-up visits.RESULTS: There were 32 eyes of 32 consecutive patients who received at least one intravitreal bevacizumab injections (range from 1 to 3). The mean length of follow-up was 4.7 (range from 3 to 8) months. The mean visual acuity improved from 20/200- at baseline to 20/100- at 1 month and 20/100+ at 3 months and last follow-up (P＜0.01). The mean central 1mm macular thickness was 483μm at baseline and decreased to 275, 314,and 301μm at 1 month,3 months, and last follow-up (P＜0.01)respectively.No adverse side effects were observed following injections in any eyes.CONCLUSION: Intravitreal bevacizumab (Avastin) showed a marked decrease in ME secondary to BRVO, improvement in visual acuity and lack of adverse side effects.

Objective To research the effects of bosentan in on unilateral ureteral obstruction (UUO) rats. Methods Wistar rats were randomly divided into three groups. UUO group was subjected to complete ligation of left ureter, sham operation group with sham operation was used as control. Bosenten group was subjected to complete ligation of left ureter and to stomach with bosentan suspension. Three groups were killed at 5,10,15,20 d. We examined renal pathological changes and the expressions of transforming growth factor-?1 (TGF-?1) in kidney of all rats using immunohistochemistry analisis method. The plasma and ureteral obstructive kidney urinary concentration of endothelin - 1 (ET - 1) was determined by radioimmunoassay. Results In Bos and UUO groups, the urinary concentration of ET - 1 increased substantially and the expression of TGF - ?1 were much higher than those in the S group. At the same time.tubulointerstitial fibrosis was present in the kidney of rats in Bos and UUO group. But the expression of TGF- ?1 and tubu-lointerstitial fibrosis in Bos group were lower than those of UUO group. Conclusion Bosentan can effectively amelirate tubulointerstitial fibrosis in rats with UUO by ET and TGF - ?1 machanism.

Objective To determine the expression of endothelin in kidneys of rats with unilateral ureteral obstruction (UUO). Methods Rats were evenly divided into two groups. Some were subjected to complete ligation of left ureter and the others with sham operation were used as control group.Four weeks later, we examined the mRNA expressions of ET-1 in kidneys of all these rats using reverse transcription-polymerase chain reaction (RT-PCR) method.The immunohistochemistry analysis was carried out to investigate the protein level of ET-1. The urinary concentration of ET-1 was determined by radioimmunoassay.Results In UUO group, the urinary concentration of ET-1 increased substantially;both gene expression and protein level of ET-1 were much higher than those in control group. At the same time, tubulointerstitial fibrosis was present in the kidneys of rats with UUO. Conclusion ET-1 is involved in the pathogenesis of the injury of UUO.

Objective To observe the long term effects of triancinolone acetonide(T-A)as a substitution for prednisone,a maintenance therapy in treating children with nephrotic syndrome(NS).Methods Twenty-five children with idiopathic NS(10 children with simple type NS and 15 children with nephritic type NS).Prednisone treatment for 4-8 weeks would bring remission,and immunosupression was added if remission failed.Then oral prednisone was reduced to 2 mg/kg per alternate day for 2 weeks,followed by a small dose of T-A(0.5-1.0 mg/kg)intramuscular injection,once a year per month for the first year,and every other month for the second year,as for the 8 frequently relapse cases,it would be every 3 months for the third year,other 17 cases stopped T-A intramuscular injection in the third year.Two weeks after T-A treatment stopped using prednisone.The relapse and the side-effects was observed through the observation of 25 NS children's clinical manifestation,routine urine test,and biochemistry variation before and during the T-A treatment,along with a 6 to 10 years follow-up survey after T-A therapy stopped.Statistical analysis was performed by using SPSS 10.0 software.Results 1.Median dose of T-A was 0.97 mg/kg per time,total doses of T-A was 18.1 mg/kg(13.5-24.4 mg/kg).2.There were 16 relapse cases by prednisone treatment,while 7 relapse cases by T-A treatment for 2 years,there existed a significant comparison(P0.05).4.There were only 4 relapsed cases in the 6-10 years of follow-up observation,the difference was sharp compared with the 16 relapsed cases before T-A treatment(P
