Objective To investigate the expression of soluble triggering receptors expressed on myeloid cells-1 ( sTREM-1 ) in intraperitoneal drainage fluid of patients with abdorminal trauma and its predictive value for post-traumatic sepsis. Methods A total of 80 abdominal trauma patients were served as the trauma group and 25 patients treated with subtotal gastrectomy as the control group.Intraperitoneal drainage fluid sTREM-1,serum sTREM-1,procalcitonin (PCT) and C-reactive protein (CRP)at 0,24,48,72 hours after admission were determined in two groups for assessing their value in early prediction of post-traumatic sepsis. Results The levels of drainage fluid sTREM-1,serum sTREM-1,PCT and CRP in the trauma group were significantly higher than those in the control group (P ＜ 0.05 ).Drainage fluid sTREM-1 showed the area under the receiver operating characteristic (ROC) curve,sensitivity and specificity for 0.84,77％,and 83％ in the prediction of post-traumatic sepsis,which was superior to the serum sTREM-1,PCT and CRP. Conclusion Intraperitoneal drainage fluid sTREM-1 has high accuracy in predicting the sepsis in abdominal trauma patients.

Objective To investigate the effect of high volume hemofiltration (HVHF) on expression of miRNA-146 in peripheral blood mononuclear cells in posttraumatic sepsis patients and its therapeutic mechanism.Methods Twenty-five cases of posttraumatic sepsis were included as HVHF group.Another 25 age-and gender-matched traumatic sepsis patients with similar APACHE-Ⅱ who received no HVHF treatment for some reasons were used as controls.Therapeutic measurements were the same of the two groups except for HVHF.At 0-,6-,12-,24-and 48-hour time points,the peripheral blood mononuclear cells were isolated from patients of both groups to detect level of miRNA-146.Peripheral blood mononuclear cells isolated at 24 hours were incubated with lipopolysaccharide (LPS) in vitro.At hours 4,8,12,24 and 48 after incubation,level of miRNA-146 in mononuclear cells was determined and levels of TNF-α,IL-6,and IL-10 in the substrate was detected by ELISA.Results (1) Level of miRNA-146 in HVHF group was decreased significantly over time as compared with that in sepsis group;(2) Before incubation and at 4-and 8-hour after incubation,miRNA-146 level was lowered significantly in HVHF group as compared with that in sepsis group.After LPS stimulation,mononuclear cell also presented a stronger inflammatory response in HVHF group than in sepsis group.Conclusions HVHF provides a definite effect on immune function recovery and a significant improvement in prognosis.Moreover,HVHF may attenuate the impact of miRNA-146 on mononuclear cell inflammatory factor release and enhance the cell ability to respond to external stimuli again via down-regulating miRNA-146,as may be one of the therapeutic mechanisms of HVHF for posttraumatic sepsis.

Objective To evaluate the combination use of thyroid fine needle aspiration biopsy (FNAB)and V-Raf murine sarcoma viral oncogene homolog B1 (BRAF) V600E gene mutation testing in differentiating benign from malignant thyroid nodules.Methods A total of 64 patients with pathologically-proved thyroid nodules were included in this study.The clinical data,including preoperative ultrasound-guided thyroid FNAB and BRAF V600E gene mutation detection,were retrospectively analyzed.Taking postoperative histopathological results as diagnostic gold standard for the thyroid nodule,the diagnostic values of simple FNAB,simple BRAF V600E gene mutation testing,and combination use of FNAB and BRAF V600E gene mutation detection were separately assessed.Results In the 62 patients a total of 64 nodules were detected (2 patients having bilateral nodules) and treated with surgery.Of the 64 nodules,BRAF V600E mutation was detected in 44 nodules,and 43 nodules were proved to be thyroid papillary carcinoma by postoperative pathological examination.Among the 44 nodules showing BRAF V600E mutation,FNAB made malignant diagnosis in 28,benign diagnosis in 6,and uncertain diagnosis in 10.Of the 20 nodules showing no BRAF V600E mutation,FNAB made malignant diagnosis in 5,benign diagnosis in 3,and uncertain diagnosis in 12.The postoperative pathological examination confirmed that 14 lesions were thyroid papillary carcinoma,4lesions were nodular goiter,one lesion was subacute thyroiditis,and one lesion was thyroid adenoma.Among the 57 thyroid papillary carcinomas,BRAF V600E mutation was detected in 43,with the mutation rate being 75.4％.Compared with the gold standard based on pathological diagnosis,the sensitivity,specificity,positive predictive value,negative predictive value,correct diagnosis rate of FNAB for judging benign or malignant thyroid nodules were 78.9％,85.7％,97.8％,33.3％ and 79.7％ respectively,which of BRAF V600E gene mutation detection for judging benign or malignant thyroid nodules were 75.4％,85.7％,97.7％,30.0％ and 76.6％ respectively,and which of FNAB plus BRAF V600E gene mutation detection for judging benign or malignant thyroid nodules were 94.7％,71.4％,96.4％,62.5％ and 92.2％ respectively.By using McNemar paired data x2 test to compare FNAB with combination use of FNAB plus BRAF V600E gene mutation detection in diagnosing thyroid nodules,the results indicated that statistically significant deference in differentiating benign from malignant thyroid nodules existed between the two methods (P＜0.001).Conclusion For the qualitative diagnosis of thyroid nodules which nature cannot be determined by simple FNAB,FNAB combined with BRAF V600E gene mutation detection can improve the diagnostic accuracy for benign and malignant thyroid nodules.

Objective To study the relationship between menstrual disorder and ovarian morphology of adolescent women in order to provide basis for diagnosis of adolescent polycystic ovary syndrome (PCOS).Methods We analyzed the clinical data of 212 patients with adolescent menstrual disorders 2 years after menstruation collected from the Department of Gynecology and Women's Health of First Affiliated Hospital of Xi'an Jiaotong University between September 2014 and September 2015.Results ① Oligomenorrhea was the most common in the 212 adolescent women (33.96 ％),followed by amenorrhea (16.51％).There was a significant difference in F-G score and acne score among patients with different types of menstrual disorder (F=1.39,1.77,all P＜0.05),the highest in those with oligomenorrhea.② The volume of the ovary,number of sinusoidal follicles,maximum area of the ovary in women with oligomenorrhea were significantly higher than those in non-oligomenorrhea women (t =2.89,5.76,6.23,all P＜ 0.05).③ Clinical manifestations differed significantly among normal ovarian group,MFO group and PCO group (x2=43.25,P＜0.05).Incidence rate of oligomenorrhea ranked the top in polycystic ovary group (49.30％),followed by multiple ovarian follicles group (42.59％),and there were significant differences in blood LH,T,and LH/FSH (F=3.45,2.43,2.76,all P＜0.05) was found in PCO group.There was significant difference in diagnosis of puberty PCOS (x2=26.58,P＜0.05).④ Among these 212 adolescent women,45 ones had puberty PCOS (21.23％).The ovary volume,number of sinus follicles,and the largest area in the obese patients were significantly higher than those in non-obese group (t =3.42,7.89,4.02,all P＜0.05);HOMA IR was also significantly higher than that in non-obese group (t =8.89,10.62,all P ＜ 0.05).Conclusion Oligomenorrhea is the most common menstrual disorder in adolescent women.Ovarian morphological abnormalities occur in most women with oligomenorrhea and obesity,who should be followed up regularly.

ObjectiveTo explore the feasibility of hilar bile duct using ultrasonography (US) in identification of different types of biliary strictures after orthotopic liver transplantation.MethodsThe US images of hilar bile duct of 62 patients with non-anastomotic biliary stricture (NAS) and 30 patients with anastomotic biliary stricture (AS) were reviewed.Four US feathers including the presence of hilar biliary dilatation,the display of hilar biliary lumen,the thickening of bile duct wall and the echo of bile duct wail were assessed.Results The presence of hilar biliary dilatation,the display of hilar biliary lumen,the thickening of bile duct wall showed a significant difference between NAS and AS groups (P＜0.001).The feature with the greatest performance in the diagnosis of NAS was unclear displayed hilar biliary lumen.The sensitivity,specificity and accuracy were 93.7％,86.7％ and 92.3％,respectively.Conclusions The observation of hilar bile duct has great vaule in identification of different types of biliary strictures after orthotopic liver transplantation.The display of hilar biliary lumen is more likely to differentiate between NAS and AS
