Objective:To explore the molecular pathogenesis of hereditary protein C (PC) deficiency due to a p. Gly86Asp variant of the PROC gene through in vitro expression experiment.Methods:Wild type and Gly86Asp mutant expression plasmids of PC were constructed and respectively transfected into HEK 293FT cells. Total RNA was extracted from the transfected cells, and the expression of PROC gene was determined by quantitative real-time PCR (qRT-PCR). PC antigen (PC: Ag) in the supernatant of cell culture and cell lysate was determined by enzyme-linked immunosorbent assay (ELISA), and the level of PC protein was detected by Western blotting. Results:qRT-PCR has detected no significant difference in the transcription level of wild-type and mutant-type PC. Compared with the wild type, the level of mutant PC: Ag in the supernatant and cell lysate were 81.3%±2.6% and 110.0%±2.8%, respectively. No difference was detected in the molecular weight between the wild-type and mutant-type PC by Western blotting. The PC content of mutant type was higher than wild-type in cell lysate, while the opposite was found with the cell culture supernatant.Conclusion:The impaired secretion by mutant PC may be the molecular mechanism of PC deficiency caused by the p.

Objective To evaluate the effects of chronic disease management on carotid atherosclerosis. Methods From May 2016 to October 2016, 500 subjects with carotid atherosclerosis diagnosed by ultrasound at the Physical examination center of the First Hospital of Jilin University were enrolled. The participants were aged 55?65(60.7±3.5) years. They were divided into the control group (n=250) and intervention group (n=250) using a random number table; a total of 20patients, 13 in the control group and 7 in the intervention group, were lost to follow-up at the end of the study. The control group only received anti-atherosclerosis treatment, while the intervention group underwent additional chronic disease management, and a 1-year follow-up study was conducted. The health of all the subjects was assessed at the beginning of the study and after the study, based on the health file. The chi-square test, two independent sample t-tests, and rank sum test were used to evaluate the effect of chronic disease management on carotid atherosclerosis. Results After 1 year of intervention, the proportion of patients with an unhealthy lifestyle (smoking, excessive drinking, high-salt diet intake, high-fat diet intake, lack of exercise, and overweight/obesity) decreased in the intervention group(10.3%, 13.1%, 7.8%, 8.6%, 6.2%, 28.0%, vs. 28.8%, 35.0%, 21.0%, 22.6%, 13.2%, 39.5%; χ2=26.49, 33.01, 17.09, 18.03, 6.80, 7.21; P<0.05), while the drug compliance increased(44.4% vs. 35.4%, χ2=4.15, P<0.05), and the total cholesterol (TC), triglyceride (TG), low density lipoproteincholesterol (LDL-C), fasting plasma glucose (FPG), uric acid (UA) and blood pressure (BP) compliance rate also increased (91.8%, 73.3%, 83.1%, 83.1%, 52.3%, 76.5%, 74.1%, 60.5%, vs. 67.5%,72.8%,28.0%,58.8%, respectively; χ2=26.86, 8.92, 15.97, 7.49, 29.81, 17.39, respectively; P<0.05); all indicators, except the drug compliance control rate, were better than those in the control group. After 1 year of intervention, the degree of carotid atherosclerosis in the intervention group was significantly reduced compared to that in the control group. Conclusions Chronic disease management could effectively interfere the control risk factors of atherosclerosis, such as smoking, drinking, obesity or overweight, BP, levels of FPG, blood lipids, and UA, improve drug compliance, delay the progression of atherosclerosis and provide a basis for the construction of the atherosclerosis management model.

OBJECTIVE:
To investigate the expression of apoptosis related protein cellular Fas associated death domain like interleukin 1 converting enzyme inhibitory protein (c-FLIP) in peripheral blood mononuclear cells (PBMCs) of patients with rheumatoid arthritis and its relation with extrinsic apoptotic pathway.
METHODS:
Sixty patients with rheumatoid arthritis were collected from Zhangzhou Affiliated Hospital of Fujian Medical University during January 2014 and June 2015, including 22 patients with low activities (DAS28<3.2), 20 patients with middle activities (3.2 ≤ DAS28 ≤ 5.1), and 18 patients with high activities (DAS28>5.1). And 25 healthy controls were also collected. The mRNA and protein expression levels of c-FLIP and the extrinsic apoptotic pathway related proteins Fas-associated protein with death domain (FADD), caspase-8 in PBMCs were detected by real-time RT-PCR and Western blot, respectively. Correlations between c-FLIP and FADD, caspase-8 in PBMCs were analyzed by pearson test.
RESULTS:
mRNA expression levels of c-FLIP, FADD and caspase-8 in PBMCs of patients with rheumatoid arthritis were all higher than those of healthy controls (all <0.05). mRNA expression levels of FADD and caspase-8 in patients with middle activities were significantly higher than those in patients with low activities (all <0.05), but the mRNA expression level of c-FLIP was not significantly higher than that in patients with low activities. mRNA expression level of c-FLIP in patients with high activities was higher than those in patients with middle or low activities (all <0.05), while the mRNA expression level of caspase-8 was lower than those in patients with middle or low activities (all <0.05). mRNA expression level of FADD in patients with high activities was higher than those in patients with low activities (<0.05). Pearson analysis showed that there was a positive correlation between c-FLIP and FADD mRNA expression (=0.323, <0.05), and negative correlation between c-FLIP and caspase-8 mRNA expression (-1.104, <0.05). The protein expression levels of c-FLIP and FADD in patients with middle activities were significantly higher than those in control group and patients with low or high activities (<0.05 or 0.01). The protein expression levels of caspase-8 in patients with middle and high activities were significantly higher than those in control group and patients with low activities (<0.05 or <0.01), and the protein expression level of caspase-8 in patients with high activities was higher than that in patients with middle activities (<0.05).
CONCLUSIONS
c-FLIP may be involved in the extrinsic apoptotic pathway in rheumatoid arthritis, and can provide reference for the evaluation of disease activities.

Objective To explore the association between the C46T polymorphism of coagulation factor Ⅻ (FⅫ) gene and the involvement of FⅫ activity (FⅫ:C) in patients with unexplained recurrent spontaneous abortion (URSA), and to elucidate its role in the pathogenesis of URSA. Methods This study included 203 patients with URSA (URSA group) and 171 healthy women with at least one child and no history of infertility or miscarriage (control group) in the southern area of Zhejiang Province. The C 46T polymorphism of the FⅫ gene was analyzed with matrix-assisted laser desorption/ionization time of flight-mass spectrometry (MALDI-TOF-MS) in all subjects. The values of prothrombin time, activated partial thromboplastin time (APTT), fibrinogen, FⅫ:C and other coagulant parameters were determined. The frequency distribution of the wild-type (CC), heterozygote (CT), homozygote (TT) genotypes and C and T alleles were compared between the patients and controls. A comprehensive analysis of association was conducted between C46T genotypes and the FⅫ:C levels in URSA patients. Results The CC, CT, TT genotypes of the FⅫgene were observed in 7 (3.4%, 7/203), 83 (40.9%, 83/203) and 113 (55.7%, 113/203) patients with URSA versus 7 (4.1%, 7/171), 46 (26.9%, 46/171) and 118 (69.0%, 118/171) controls. The frequency of CT in the patients with URSA was significantly higher than that in controls, but the frequency of TT in the patients was lower than that in controls (χ2=7.939, OR=1.884, 95%CI:1.210-2.935, P<0.05). The frequencies of allele C and allele T were observed in 97 (23.9%, 97/406) and 309 (76.1%, 309/406) patients with URSA versus 60 (17.5%, 60/342) and 282 (82.5%, 282/342) controls. The distribution frequency of allele T in URSA group was lower than that in control group (χ2=4.510, OR=1.475, 95%CI:1.029-2.115, P<0.05). The FⅫ:C levels in the patients were (102±13)%in CC genotype, (78±11)%in CT genotype and (59± 9)%in TT genotype, respectively. The differences of the FⅫ:C levels between the CC and CT, CT and TT, CC and TT genotypes in the patients were significant (all P<0.05). Conclusions The low level of FⅫ:C maybe result from the T allele of the FⅫgene in URSA patients. The CT genotype might be relative to the pathogenesis of URSA in a Chinese Han female population from the southern area of Zhejiang province.

Polyethylene glycol (PEG) is extensively used to increasing the in vivo and in vitro stability of liposomes. However, PEGylated liposomes also produce some negative effects with further research, such as low cellular uptake, poor "endosomal escape" of pH sensitive liposome (PSL) and accelerated blood clearance (ABC) phenomenon, and this situation is referred as the "PEG dilemma". "PEG dilemma" posed severe challenges for the targeted delivery of PEGylated liposomes-loaded anticancer drugs, effective intracellular release of PEGylated PSL-encapsulated gene and protein drugs, and repeated administration of PEGylated liposomes. Therefore, it is urgent to solve the "PEG dilemma". This review focused on the definition, classification of "PEG dilemma", and discussed several possible approaches to overcome "PEG dilemma".
