Objective To discuss whether potassium sensitivity test(PST) is correlated with PUF in Interstitial Cystitis (IC). Methods The data of 14 IC patients (female 13, male 1) were an-alyzed. The mean age was 48 years (range 35-67 years). The clinical symptoms included urinary fre-quency, urgency, pelvic and peritoneal region pain after bladder filling. All the patients met the diag-nostic criteria of NIDDK for IC. Dilatations by hyponome were performed, medicine including heparin-sodium, lidocaine, NaHCO3 were used by intravesical instillation. PST and the pelvic pain and urgen-cy/frequency patient symptom (PUF) were used for evaluation. The relationship of the PST and PUF was assessed by statistics. Results PST median decreased from 4.0 to 1.0 (P<0.01). PUF medi-an decreased from 27.5 to 13.5(P<0.01). PST was directly correlated with PUF (rs=0. 868, t= 4.418, P= 0.001 before treatment, rs = 0.779, t=4.300, P = 0.001 after treatment). Conclusions PST and PUF are correlated. Both can be used as index in diagnosis, differential diagno-sis, symptom severity and treatment effectiveness evaluation of IC.

Objective To evaluate the prognostic value of intraoperalive detection in rib bone marrow micmmetastasis(BMMs)of patients with non-small-cell lung cancer(NSCLC)and the relationship between the micROmetast ases and clinicopathologic factors.Method From April 2004 to May 2007,146 patients undergoing surgical treatment for NSCLC were prospectively investigated for the presence of BMMs by the immunohistochemisury method.Remits 30.82%(45/146)of NSCLC patients were detected with BMMs,15(33.33%)patients developed remote metastases of the 45 patients with BMMs,14(13.86%)patients developed metastases of the 101 patients without BMMs.Patients with BMMs demonstrated an earlier metastasis and a lower survival rate compared with patients without BMMs(P＜0.05).There Was trend for ahigher frequency and the occurrence of BMMs changed with tumor stages and the histologic differentiation of the tumor.No relationship was found between BMMs and age,T grade,as well as tumor dimension.Conclusions The detection of BMMs can predict the prognosis of NSCLC patients and identifies patients withNSCLC who are at significantly increased risk for metastasis and survival,which may be useful in evalnatingpatients for adjuvant treatment

Objective To evaluate the prediction value on distant metastases of fib bone marrow micrometastases (BMM) of patients with non-small lung cancer ( NSCLC ). Methods From January 2003 to March 2006, 168 patients undergoing surgical treatment for NSCLC were prospectively investigated for the presence of BMM by using immnnohistochemistry. The sensitivity and specificity of the rib bone marrow micrometastases technique were also calculated. Receiver operating characteristic curve (ROC curve)was drawn according to data. Results Occult BMM were detected in 29.76 %(50/168) of patients with NSCLC. 15(29.76 %) patients developed metastases in the 50 patients with BMM and 15 (12.71%) patients developed metastases in the 118 patients without BMM. The sensitivity and the specificity of the technique was 61.54 % and 79.84 %. The false negative rate was 38.46 % and the false positive rate was 20.16 %. The positive predictive value, negative predictive value and Youden' s index were 87.5 %, 93.33 %, 74.33 % respectively. Conclusion The detection of BMM could predict the distant metastases of non-small lung cancer patients through receiver operating characteristic curve evaluation, however, the detecting sensitivity should be improved.

Objective To study relationships between myocardial injury and the levels of serum complement C3, C4 and C5b-9 in patients with acute coronary syndrome (ACS). Methods A retrospectively analysis was conducted. 170 ACS patients [including 110 cases of ST-segment elevation myocardial infarction (STEMI) and 60 cases of non-ST-segment elevation acute coronary syndrome (NSTE-ACS)] with ischemic chest pain or chest discomfort onset within the prior 12 hours admitted to the cardiology department of Tianjin Union Medicine Center from January 2014 to July 2016 were enrolled. Thirty-six healthy cases were enrolled as control during the same time. The levels of serum complement C3, C4 and C5b-9 on 1, 3 and 7 days after admission and myocardial function indicators were analyzed. Major adverse cardiovascular events (MACE) and readmission rate were analyzed after 1 year follow-up. The correlation between serum complement levels and myocardial function indicators was analyzed by Pearson correlation analysis. Results ① The levels of serum C3, C4 and C5b-9 on the first day in NSTE-ACS group and STEMI group were significantly higher than control group [C3 (g/L): 1.04±0.33, 1.26±0.35 vs. 0.39±0.21, C4 (g/L): 0.31±0.14, 0.33±0.10 vs. 0.19±0.07, C5b-9 (g/L): 575.46±197.26, 659.26±160.77 vs. 501.40±141.51, all P < 0.05]. There were no changes of serum C3, C4 in NSTE-ACS group, but C5b-9 decreased after a peak (g/L: 700.63±218.42) at 3 days. Serum complements in STEMI group reached peak on the third day [C3 (g/L): 1.37±0.33, C4 (g/L): 0.42±0.12, C5b-9 (g/L): 754.72±136.22]. The levels of serum C4 and C5b-9 in STEMI group were higher than NSTE-ACS group on the third and seventh day. ② The levels of troponin T (TnT), creatine kinase-MB (CK-MB), solution intercellular adhesion molecule-1 (sICAM-1), global registry of acute coronary events (GRACE) scores and percutaneous coronary intervention (PCI) numbers in STEMI group were significantly higher than those in the NSTE-ACS group, which were as opposite as left ventricular ejection fraction (LVEF). However, there were no significant differences in levels of serum N-terminal pro-brain nitric peptide (NT-proBNP), Fibrinogen (Fib), readmission rate and incidence of MACE between STEMI and NSTE-ACS groups. ③ According to GRACE, patients with ACS were divided into low risk group (≤ 108 scores, 26 cases), intermediate risk group (109-140 scores, 61 cases) and highest group (> 140 scores, 83 cases). TnT and sICAM-1 in intermediate risk group were significantly increased as compared with low risk group. Levels of TnT, sICAM-1, C3, C4 and C5b-9 in the highest group were significantly higher than the low and intermediate risk groups, however the lowest LVEF was found in the highest group. ④ It was shown by Pearson correlation analyses that levels of serum C3, C4, C5b-9 were positively correlated with TnT (r value was 0.481, 0.367, 0.292, respectively, all P <0.01), sICAM-1 (r value was 0.298, 0.249, 0.365, respectively, all P < 0.01), but negatively correlated with LVEF (r value was -0.384, -0.260, -0.200, respectively, all P < 0.01). In addition sICAM-1 positively correlated with TnT (r = 0.536, P = 0.000), but negatively correlated with LVEF (r = -0.341, P = 0.001). Conclusions Serum complements activation was found in the acute phase of ACS patients. Serum complement C3, C4 and C5b-9 are involved in the process of myocardial injury, and may reflect severity of myocardial injury and cardiac dysfunction.

Objective To investigate the xenotransplantation model of fetal pig skin precursor tissue and its development after transplantaion. Methods Porcine skin precursor tissue was obtained from the embryo of gestation day 56 (E56), and made into microskin or stamp skin graft. The microskin was transplanted to the dorsal wound in BALB/c nude mice, then covered with human corpse skin. The stamp skin graft was imbedded subcutaneously into the back of nude mice, and microskin was injected subcutaneously into the auricles of nude mice. Their growth and development were observed and they were examined by HE staining at 6th and 12th week after transplantation respectively. Two-sample t test was used to analyze the size of newly grown skin tissue. Results Porcine skin precursor tissue graft in three models above survived and continued growth after transplantation, and growth ability of the dorsal wound transplantation model was significantly stronger than that of the auricle model. Epidermis and hypodermis were detected in newly grown skin tissues. Hair follicles, a few of sebaceous glands, but no sweat glands were observed in auricle model, while many sebaceous glands and sweat glands were observed in the dorsal wound model. Conclusion Transplantation of microskin to dorsal wound is the optimal model of investigating the xenotransplantation of fetal pig skin precursor tissue and its development after transplantion.

objective The roles of TLRs and their signal pathway in gouty arthritis(GA)were explored.Methods TLR2 and TLR4 mRNA was measured using real-time quantitative polymerase chain reaction(RT-PCR)in PBMCs,IL-1β level was detected using ELISA in plasma,and NF-κB p65 protein level in PBMCs was measured using Western blot.Level of TLR2 mRNA,ILR4 mRNA,IL-1β,NF-κB p65protein was compared among acute GA,non-acute GA and healthy controls.Correlation between TLR2mRNA,TLR4 mRNA and serum uric acid,IL-1β level in GA patients was analyzed.One-way ANOVA was used to analyze data between multiple groups and q-test was used for two-two comparison.Spearman's analysis was applied for correlation analysis.Resuits The expression of TLR4 mRNA,NF-KB p65 protein,IL-1β arid serum uric acid level in patients with acute GA [(5.0±1.2), (7.11±0.18), (283±83)pg/ml,[585±123)μmol/L] was significantly increased compared to non-acute GA[(2.3±0.4),(0.63±0.06),(134±29)pg/ml,(493±107)μmol/Lj and healthy controls(1.1±0.6),(0.52±0.12),(97±17)pg/ml,(326±65)μmol/L](P<0.01,respectively).Significant diffefence was also observed between non-acute GA patients and healthy controls(P<0.05,respectively).The level of TLRR4 mRNA was positively correlated with uric acid and IL-1β level in GA patients(rs=0.876,0.779;P<0.05,respectively).Conclusion Innate immunity are activated by membrane-type pattern recognition receptors in primary GA.TLR4-NFκB p65-IL-1β signat transduction may participate in the inflammatory mechanisms of gout.Urate crystals in patients with gout may:be involved in the activation of TLR4 and its signal pathway.

Objective:To study the CT features for solitary fibrous tumor (SFT) in the abdomen and pelvis and to improve the diagnostic accuracy.Methods:Fourteen patients with SFT were collected in our hospital from January,2011 to December,2015.Characteristic of images were analyzed and compared for 10 SFT,which located outside the abdominal organs with extragastrointestinal stromal tumors (EGIST),leiomyosarcoma,and schwannoma.Results:Necrosis and cystic formation were frequently present in SFT in the abdomen and pelvis.CE-CT showed serpentine vessels along the periphery,while pattern of enhancement was maplike inhomogeneous progressive.Comparing with the EGIST or schwannoma,the difference of CT value in non-contrast and the arterial phase were statistically significant (P＜0.05).The numbers of peritumoral circuity vessel were significantly different between SFT and EGIST (~=18.27,P＜0.008) or between SFT and schwannoma (x2=19.25,P＜0.008).Comparing with the leiomyosarcoma or schwannoma,SFT located outside the abdominal organs.We found that tumor necrosis rate was significantly different between SFT and leiomyoscarcoma (x2=8.00,P＜0.008).Conclusion:SFT in the abdomen and pelvis show certain CT characteristics.The CT value in noncontrast and at the arterial phase,tumor necrosis rate,and serpentine vessels along the periphery were pivotal in differentiating SFT from leiomyosarcoma,EGIST and schwannoma.
