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

The experiment was performed at the Laboratory of Ultrasonic Medicine,Department of Biomedical Engineering,Tianjin Medical University between October 2007 and July 2008.Finite difference time domain method which was proposed by Morita to simulate nonlinear ultrasound transmission was applied together with bio-heat-transfers-equation to simulate temperature distribution in the focal region.The results show that when there was a blood vessel in tissue,the blood vessel temperature rise was lower than the surrounding tissue temperature rise.The highest temperature in the surrounding tissue and the focal region above 60 ℃ were decreased with increasing vessel diameter.The blood vessel diameters lead to great changes of temperature distribution.We should consider the influence of blood vessel diameters during high intensity focused ultrasound therapy to destroy tumors

Objective To investigate the expression and significance of ABCG2 and ALDH1 in malignant transformation of ovarian endometriosis.Methods The protein expressions of ABCG2 and ALDH1 were detected with immunohistochemistry in 38 cases of malignant transformation of ovarian endometriosis(EMs malignant transformation group),35 cases of endometriosis(EMs group)and 30 cases of normal endometrium(control group).Results The positive rates of ABCG2 and ALDH1 expressions in EMs malignant transformation group were significantly higher than those in EMs group and control group(P<0.05).The expressions of ABCG2 and ALDH1 were significantly associated with the serum CA125 level,differentiation and clinical stage of malignant transformation of ovarian endometriosis (P<0.05),but were not related to the patient′s age,dysmenorrhea history and pathology type(P>0.05).There was no correlation between the expression of ABCG2 and ALDH1 in malignant transformation of ovarian endometriosis(P>0.05).Conclusion The expressions of ABCG2 and ALDH1 might be involved in malignant transformation of ovarian endometriosis.

Hepatic encephalopathy is a common metabolic neuropsychiatric syndrome in the development of end-stage liver disease. Since the concept of intestinal-liver-brain axis was proposed, the relationship between the pathogenesis of hepatic encephalopathy and the gut microbiota has been a hot research topic. In recent years, studies have confirmed that gut microbiota is involved in and affects various pathological processes of hepatic encephalopathy. This article combines the latest research progress at home and abroad to elaborate on the research status of regulating gut microbiota and thus interfering with the pathological process of hepatic encephalopathy, hoping to provide new ideas and methods for the intervention of hepatic encephalopathy based on the regulation of gut microbiota.

To established an effective GC-MS /MS method for the contents determination of the residual DEHP in injection equipment, and investigate the effect of the pretreatment on the measurement. To simulate the clinical conditions of use, under the condition of 37 degrees C balance extraction, extract liquor by chloroform extraction, then the extract followed by analysis of GC-MS /MS. The method was simple, rapid, sensitive and accurate. The limits of quantitation (LOQ, S/N = 5) of cyclohexanone was 0.075 μg/mL, The spiked average recoveries ranged from 92% to 98%. The relative standard deviations (RSDs) of the method ranged from 1.01% to 1.61%, The method was simple, fast, sensitive and accurate, and may serve as a mass control method for residual DEHP in injection equipment.

Objective To investigate the dynamic changes and its significance of inflammatory factors in cervical secretions and prior cervical tissues after cervical conical resection.Methods Women who received prior cervical conization during December 2013 and December 2015 in this hospital were selected,then the cervical tissue and secretion were collected regular interval after the conization.The expression of tumor necrosis factor-α(TNF),interleukin 6 (IL-6) and high mobility group protein 1 (HMGB1) were quantitative detected and analyzed.The expression and infiltration of inflammatory cell were detected by HE and immunohistochemical staining.Results The expression of TNF-α,IL-6 and HMGB1 in cervical tissues and secretions increased gradually after priorcervical conization,which reached the peak at 1 to 2 weeks after priorcervical conization,and then gradually decreased,the differences were statistically significant when compared with the preoperative control group (P＜0.05).The inflammatory cell infiltration and the inflammatory response were most severe at 1st week after the conization.The expression of TNF-α,IL 6 and HMGB1 was at 1st week after the conization were significantly higher than that of the 4thweek group.Conclusion The cervical inflammatory were most severe after the prior cervical conization about 1-2weeks,and the hysterectomy should be avoided at this stage.

Objective To investigate the clinical and neuroimage characteristics of reversible posterior leukoencephalopathy syndrome (RPLS) in Chinese elderly patients. Methods The characteristic clinical presentation and neuroimaging of 5 elderly patients with RPLS were retrospectively analyzed. Results There were one male and four females in this study, with the average age of (63.0±2.4) years, all combined with hypertension. The most common clinical presentations were abnormality of visual perception (5 cases), headache (4 cases), epileptic seizure (4 cases), disturbance of consciousness (3 cases), pathological reflex (2 cases) and hemiplegia (2 cases). CT scan showed 4 cases with low density lesions. MR1 scan showed 5 cases with occipital lobe lesions, 2 with parietal lobe lesions and 1 with temporal lobe lesions. Re-examination of CT scans showed that 4 survived patients became normal at mean (48.8±29.2) days after discharging from hospital. Conclusions The etiologies of RPLS are diverse. The vasogenic theory is supported by neuroimage of RPLS. Neuroimage may be very important for the diagnosis of RPLS. Diffusion-weighted imaging and apparent diffusion coefficient map may be helpful for differential diagnosis between RPLS and cerebral infarct.
