A comparative study of systemic lupus erythematosus in 39 male(MSLE) and 120 female (FSLE) patients was carried out. The results showed that, in MSLE, the mean age at the time of disease onset was similar to FSLE, and the clinical features were nearly the same as those in females, except that the first signs of MSLE were less complicated than those of FSLE, malar rash occurred less commonly in MSLE than in FSLE(P

Objective To investigate the chang and impaction of TM and D- Dimer on peripherally inserted central catheter (PICC) associated thrombosis in cancer patients. Methods The expression of TM and D-Dimer from 207 cancer patients with PICC was examined using nzyme-linked immunoassay. Paitents were divided into thrombosis group and control group according to Doppler Sonography. Results The thrombosis group had 33 cases and the control group had 174 cases in 207 malignant tumor patients with PICC. Compared with that in control group, the expression of TM (6.806 ± 1.805)μg/L and D-Dimer (0.786 ± 0.294) mg/L was significantly higher in thrombosis group and respectively statistically significant (P<0.05), The expression of TM and D-Dimer was positively correlated with thrombosis respectively (r=0.572 and 0.530, P<0.05). The multi-factor Logistics analysis showed the odd ratio of TM was 1.899 and the odd ratio of D-Dimer was 7.292, and the difference was statistically significant (P<0.05). Patients were dichotomized into elevated and noneelevated groups according to the 50th percentile of the levels of TM and D-Dimer of the total study population. In multivariable analysis, the odd ratio of both elevated TM and elevated D-Dimer was 2.04, which was higher than elevated TM (1.286) alone and elevated D-Dimer (1.044) alone, and there was difference in statistics (P<0.05). The results showed that the risk of PICC associated with thrombosis in both elevated TM and elevated D-Dimer TM increased 2.042 times. The expression of TM and D-Dimer was correlated with clinical stage respectively (r=0.477 and 0.492, P<0.05);but was not correlated with age, sex, site of tumor and concurrent radiochemotherapy (P>0.05). Conclusions The expression of TM, D-Dimer is elevated, which is expected to assess the early diagnosis and clinical value of PICC associated thrombosis in cancer.

Abstract: Objective　To investigate the expression level and clinical significance of serum liver fibrosis-associated lncRNA1 (lnc-LFAR1) in patients with chronic hepatitis B cirrhosis, aiming to analyze its correlation with interleukin-6 (IL-6), interleukin-1β (IL-1β), and liver function. Methods　Patients with chronic hepatitis B (CHB) cirrhosis and CHB diagnosed and treated in Dongguan City People's Hospital from March 2016 to December 2019 were selected and divided into the liver cirrhosis group (n=80) and the CHB group (n=80), and 80 healthy people with physical examination during the same period were selected as healthy group. The serum levels of lnc-LFAR1, interleukin-6 (IL-6), albumin (ALB), interleukin-1β (IL-1β) and liver function indicators, including albumin (ALB) and alanine aminotransferase (ALT) were measured and analyzed. The correlation between serum lnc-LFAR1 expression level and IL-6, IL-1β was assessed, and the levels of lnc-LFAR1, IL-6, IL-1β, ALB and ALT were compared among patients with CHB cirrhosis of different Child-Pugh grades. Results The serum levels of lnc-LFAR1, IL-6, IL-1β and ALT in the patients with liver cirrhosis [(1.85± 0.62), (41.76±13.92) ng/mL, (7.78±1.95) pg/mL, (148.37±29.67) U/L] were higher than those in the CHB group [(1.42±0.47), (23.56± 7.85) ng/mL, (5.42±1.41) pg/mL, (87.59±17.52) U/L] and the healthy group [(1.01±0.34), (6.70±2.23) ng/mL, (3.13± 0.78) pg/mL, (15.44±3.10) U/L] (P<0.05), while the ALB levels (30.54±3.82) g/L were lower than those in the CHB group (37.27±4.34) g/L and the healthy group (45.26±5.66) g/L (P<0.05). Serum lnc-LFAR1, IL-6, IL-1β and ALT levels in the CHB group were higher than those in the healthy group (P<0.05), and ALB levels were lower than those in the healthy group (P<0.05); the serum levels of lnc-LFAR1, IL-6, IL-1β in patients with CHB cirrhosis were negatively correlated with ALB (P<0.05), and positively correlated with ALT (P<0.05); the serum expression level of lnc-LFAR1 in patients with CHB cirrhosis was positively correlated with IL-6 and IL-1β (r=0.598, 0.571, P<0.05); with the increase of Child-Pugh grade, the serum levels of lnc-LFAR1, IL-6, IL-1β, and ALT in patients with CHB cirrhosis gradually increased (P<0.05), and the level of ALB gradually decreased (P<0.05). Conclusions Serum lnc-LFAR1 expression level is higher in patients with CHB cirrhosis, which is obviously related to IL-6, IL-1β, ALB and ALT. Therefore, the evaluation of serum lnc-LFAR1 expression level is helpful in the clinical assessment of the condition of CHB cirrhosis patients.

Objective To investigate the effects of ginsenoside Rg3 on growth and apoptosis of gastric cancer cell line MKN-45 and SGC-7901 in vitro. Methods MKN-45 and SGC-7901 cells at logarithmic growth phase were obtained, and were cultured with ginsenoside Rg3 of different concentrations (20, 30, 40, 50 μg/mL) for 24, 48 h or 24, 48 and 72 h. Cells cultured without ginsenoside Rg3 were served as controls. The inhibition rates of ginsenoside Rg3 on MKN-45 and SGC-7901 cells were detected by MTT assay, apoptosis rate of SGC-7901 cells was determined by Annexin V/PI double staining flow cytometry, cell cycles of SGC-7901 cells were analysed by flow cytometry, and morphological changes of SGC-7901 cells in 50 μg/mL ginsenoside Rg3 treatment group were observed by transmission electron microscopy. Results The inhibition rates on MKN-45 and SGC-7901 cells in each ginsenoside Rg3 treatment group were significantly higher than those in control group (P < 0.05), and the inhibition rates increased with the concentrations of ginsenoside Rg3 and time of culture ( P < 0.05). Compared with control group, the apoptosis rates of SGC-7901 cells and percentages of cells in G_1/G_1 cell cycle in each ginsenoside Rg3 treatment group were significantly increased in a concentration and time dependent manner. Typical morphology of SGC-7901 cell apoptosis was observed by transmission electron microscopy in 50 μg/mL ginsenoside Rg3 treatment group. Conclusion Ginsenoside Rg3 has significant inhibition effect on gastric cancer cell lines in vitro with a concentration and time dependent manner, the mechanism of which may involve the induction of gastric cell line apoptosis.

9α-hydroxy-4-androstene-3,17-dione (9-OH-AD) is an important intermediate in the steroidal drugs production. 3-ketosteroid-9α-hydroxylase (KSH), a two protein system of KshA and KshB, is a key-enzyme in the microbial steroid ring B-opening pathway. KSH catalyzes the transformation of 4-androstene-3,17-dione (AD) into 9-OH-AD specifically. In the present study, the putative KshA and KshB genes were cloned from Mycobacterium smegmatis mc(2)155 and Gordonia neofelifaecis NRRL B-59395 respectively, and were inserted into the expression vector pNIT, the co-expression plasmids of kshA-kshB were obtained and electroporated into Mycobacterium sp. NRRL B-3805 cells. The recombinants were used to transform steroids, the main product was characterized as 9α-hydroxy-4-androstene-3,17-dione (9-OH-AD), showing that kshA and kshB were expressed successfully. Different from the original strain Mycobacterium sp. NRRL B-3805 that accumulates 4-androstene-3,17-dione, the recombinants accumulates 9α-hydroxy-4-androstene-3,17-dione as the main product. This results indicates that the putative genes kshA, kshB encode active KshA and KshB, respectively. The process of biotransformation was investigated and the results show that phytosterol is the most suitable substrate for biotransformation, kshA and kshB from M. smegmatis mc(2)155 seemed to exhibit high activity, because the resultant recombinant of them catalyzed the biotransformation of phytosterol to 9-OH-AD in a percent conversion of 90%, which was much higher than that of G. neofelifaecis NRRL B-59395. This study on the manipulation of the ksh genes in Mycobacterium sp. NRRL B-3805 provides a new pathway for producing steroid medicines.
