Objective To investigate the diagnosis and operation treatment of primary intrahepatic cholangiocelhlar carcinoma (PICC), for improving the level of diagnosis and treament of PICC. Methods The clinical data of 18 cases with PICC confirmed by operation were analyzed retrospectively. Results In the early stage, no specific symptoms was found in all the 18 cases, the positive cases of AFP, CEA, CA199 and live cirrhosis were 2, 4, 3 and 4. The diagnostic rates of ultrasound examination, CT and MRI were 11.1%(2/18), 42.9%(6/14) and 45.5% (5/11 ). Seven cases were diagnosed as suffering from PICC and the others were misdiagnosed. Of all the 18 patients, 8 cases underwent radical resection and 10 cases received palliative excision. Conclusions PICC patients lack clinical features and serum tumor marker,the rato of misdiagnosis is high, but that of radical resection is low. Knowing its clinicopathological features well. Radicalresection is the best way for treatment of PICC.

Objective To evaluate the clinical significance of serum levels of ProGRP, TPS and NSE in diagnosis and therapy monitoring in small cell lung cancer patients. Methods The levels of serum ProGRP, TPS and NSE in 51 SCLC patients (SCLC group), 60 benign pulmonary disease patients (benign disease group ) and 60 healthy people (healthy group ) were determined using chemiluminescent immunoassay, ELISA and electrochemiluminescent immunoassay respectively. Blood samples were collected and detected prior to therapy, before the second course of chemotherapy and the third course of chemotherapy consecutively in all the 51 SCLC patients. Results The serum ProGRP, TPS and NSE concentrations prior to chemotherapy in limited stage SCLC (LSCLC) were 136. 9(22.8-631.7)ng/L, 78. 2(56.4-114.6) U/L and 28.1(20.9-46.1)μg/L, respectively; And in extensive stage SCLC patients (ESCLC) were 1 106.6(41.2-2161.1) ng/L, 230. 9( 143.5-259.0) U/L and 81.1 (34.3-140.0)μg/L, respectively. The serum concentrations of the 3 markers in benign disease group were 19. 7 ( 9. 5-29. 1 )ng/L, 48. 7 ( 17.9-95.4) U/L and 12. 1(1.2-13.9) μg/L; and in healthy group were 20.3(10.7-30.6) ng/L, 50.3(19.5-70.7) U/L and 11.7 (1.1-13.4)μg/L, respectively. The Kruskal-Wallis test showed significantly statistical difference in different groups of the 3 tumor markers, Chi-Square were 51. 368,36. 532 and 81. 645( P <0. 01 ). Significant statistically differences showed when the concentrations of the 3 marks of the 2 control group were compared with that of the LSCLC group ( U =491, 827, 609 and 476, 831, 585,respectively, P < 0. 05 ). Differences were also statistically significant when the 2 control group compared with that of the ESCLC group ( U = 314,532,456 and 302,553,430, respectively, P < 0. 01 ). The AUC of ProGRP was 0.832 +0.029(95% CI:0.774-0.890). When cutoff value of ProGRP set as 37.7 ng/L, the diagnostic sensitivity, specificity, positive predictive value, negative predictive value and Youden's index were 71% (36/51), 97% (116/120), 90% (36/40), 89% ( 116/131 ) and 67%, respectively; show good detection performance. The sensitivity increased to 92%, 86%, 92% and 88%, when combination detection of ProGRP + TPS + NSE, ProGRP + TPS, ProGRP + NSE and TPS + NSE were used, and the specificities were 77%, 77% , 92% and 77% accordingly. The Fridman test showed significantly statistical difference in the 3 tumor markers at different stages of treatment, x2 were 49. 120, 10. 614 and 44. 392, P <0. 01. After the first chemotherapy course, all the tumor marker levels except TPS decreased significantly in comparison with the pretreatment concentrations. However, only ProGRP levels showed a progressive drop during the two consecutive courses of therapy, and the median concentrations were 68.0 ( 18. 6-158.4 ) and 21.0( 14. 9-63.5) ng/L (compared to the level before therapy,Z=-4. 889 and -5. 594, P <0. 01 ). The median of serum TPS increased slightly to 105.2 (54. 1-181.2 ) U/L after the first chemotherapy course (Z=-1.248, P>0.05), and decreased significantly to 79.0(48.7-155.3) U/L after the second chemotherapy course (Z=-2.484, P<0. 05 ). As to the NSE, the median concentration decreased to 11.8(8.0-16.0)μg/L after the first chemotherapy course ( Z= - 5. 568, P < 0. 01 ). However, the median was 10. 6(9.0-12.7)μg/L, which showed no significant decrease after the second chemotherapy course (Z=-1.851, P>0.05).Forty-six SCLC patients evaluated as clinical remission ( 3 CR and 43 PR) after the second chemotherapy course, among them there were 38 patients (83%) with normal serum ProGRP, TPS and NSE level ( 19 patients) or with only 1 abnormal tumor level ( 19 patients). There were only 2 patients with all abnormal serum ProGRP, TPS and NSE level, and both patients were evaluated as clinical PD. Two patients with 2 abnormal tumors results were classified as SD, the only 1 patient without therapy evaluation also had 2 abnormal tumor marker results. Conclusions The serum ProGRP, TPS and NSE are valuable tumor markers for diagnosis and treat monitoring of SCLC, particularly the ProGRP + NSE shows the highest clinical value. Combing detection of the 3 tumor markers are valuable for therapy monitoring and prognosis in SCLC patients.

Objective:To analyze the serum and urinary amino acid (AA) profiles of urolithiasis patients to explore the potential biomarkers for clinical screening and early diagnosis.Methods:Case-control study. Serum and urine samples were collected from 74 urolithiasis patients (aged 20-82 years, 41 men, 33 female) in the department of urology of the First Affiliated Hospital of Fujian Medical University and 35 healthy controls (HC, aged 22-80 years old, 20 men, 15 female) from the health examination center from February 2015 to October 2017. Serum and urinary AA levels of patients and HC were analyzed using Gas Chromatography-Mass Spectrometry (GC-MS) based metabolomic strategy. The multivariate statistical analysis methods of principal component analysis (PCA) and orthogonal partial least squares discrimination analysis (OPLS-DA) were employed for modeling. The variable importance projection (VIP) value of OPLS-DA model>1 and P<0.05 of t test were selected to screen the differential amino acid metabolites. The diagnostic capabilities of potential markers were evaluated by receiver operating characteristic (ROC) curve and binary logistic regression analysis. Results:Five AA metabolites including serine, glutamate, aspartic acid, isoleucine and glycine were found, which had statistically significant differences between the patient group and the control group ( P<0.05) and were associated with seven metabolic pathways. Serum serine, glutamate, aspartic acid, isoleucine and urine glycine and aspartic acid were combined into an integrated marker panel whose AUC value was 0.890, the sensitivity was 78.0%, and the specificity was 96.4%. Conclusion:Five amino acids in serum and urine could be used as an integrated biomarker panel for the clinical screening and early diagnosis of urolithiasis, which could provide some experimental basis for molecular urolithiasis research.

Porcine interferon-alpha (pIFN-alpha) fermentative production by recombinant Pichia pastoris was carried out in a 10-L bioreactor to study its metabolism changes and effects on fermentation under different inducing strategies, by analyzing the change patterns of the corresponding metabolism and energy regeneration. The results show that the specific activities of alcohol oxidase (AOX), formaldehyde dehydrogenase (FLD) and formate dehydrogenase (FDH) largely increased when reducing temperature from 30 degrees C to 20 degrees C under pure methanol induction, leading significant enhancements in methanol metabolism, formaldehyde dissimilatory energy metabolism and pIFN-alpha antiviral activity. The highest pIFN-alpha antiviral activity reached 1.4 x 10(6) IU/mL, which was about 10-folds of that obtained under 30 degrees C induction. Using methanol/sorbitol co-feeding strategy at 30 degrees C, the major energy metabolism energizing pIFN-alpha synthesis shifted from formaldehyde dissimilatory energy metabolism pathway to TCA cycle, formaldehyde dissimilatory pathway was weakened and accumulation of toxic intermediate metabolite-formaldehyde was relieved, and methanol flux distribution towards to pIFN-alpha synthesis was enhanced. Under this condition, the highest pIFN-alpha antiviral activity reached 1.8 x 10(7) IU/mL which was about 100-folds of that obtained under pure methanol induction at 30 degrees C. More important, enhanced pIFN-alpha production with methanol/sorbitol co-feeding strategy could be implemented under mild conditions, which greatly reduced the fermentation costs and improved the entire fermentation performance.
