The biochemical mechanism of degrading keratins by S.fradiae var S-221 was primarily studied.The compounds (Na_ 2 SO_ 4 , Na_ 2 SO_ 3 and sulfdryl acohol), which respecitively enhance specific activity of keratinase, activate keratinase intensively and mainly act on the disulfide bonds reductase in the keratinase, Na_ 2 SO_ 3 activates intensively both disulfide bonds reductase and polypeptide hydrolytase at 0.01 mol/L, whereas Na_ 2 S_ 2 O_ 3 , which acts on the disulfide bonds reductase, inhibits keratinase.On the condition that substrate, keratins exists, S.fradiae var S-221 is induced to produce exo-keratinase, which is a multiproteinase, containing disulfide bonds reductase, which is a key enzyme degrading keratins, then, with polypeptidic, hydrolytase, graduately hydrolyzates denatured keratins into polypeptides, oligopeptides and free amino acids, so that keratins have been decomposed completely.Sulfur in the keratins was transferred into sulfhydryl compounds, H_ 2 S and sulfates in the course of keratinolysine.

The aim of this study was to observe the inhibitory effect of daunorubicin on KG1a cells and the expression of Eps8 which is a novel tumor-associated antigen with its full name epidermal growth factor receptor pathway substrate 8 (Eps8), and to explore the effect of daunorubicin on Eps8 expression in KG1a cells at mRNA and protein levels. The KG1a cells were treated with different concentration of daunorubicin for 24, 48, 72 h, then trypan blue staining was used to detect the inhibitory rate of KGla cells, RQ-PCR and Western blot were used to detect Eps8 mRNA and Eps8 protein expression. The results showed that daunorubicin inhibited the proliferation of KG1a cells in a dose and time dependent manner (r = 0.983, P < 0.01). Daunorubicin could reduce the mRNA and protein levels of Eps8 expression in dose and time dependent manners in KG1a cells (r = 0.979, P < 0.05). It is concluded that with the increasing of concentration and time of daunorubicin acting on KG1a cells, the cell proliferative inhibitory effect increased and the expression of Eps8 decreased, suggesting that the inhibitory effect of daunorubicin on KG1a cell proliferation is realized through downregulation of Eps8 expression.

BACKGROUNDDilation resistance to stenting in non-calcified coronary plaques was compared in patients with percutaneous coronary intervention (PCI) in order to confirm the clinical usefulness of multislice computed tomography in examining coronary plaque type and to provide information pertaining to the effects of plaque type on dilatation resistance.

METHODSA retrospective analysis of 64-slice computed tomography coronary imaging data collected in the month prior to coronary stenting in 93 patients (65 male and 28 female, mean age of (57.22±7.22) years) was conducted. Non-calcified coronary plaques were divided into lipid-rich (lipid content >25% of plaque volume) and fibrous plaques according to the Hammer-Hansen S method: where lipids, fiber, and intraluminal components were indicated by contrast using Hu values of -100-49, 50-129, and >130, respectively. Clinical features, pre-dilatation balloon specifications and filling pressure, and stent size and release pressure were compared.

RESULTSHigh-sensitivity C-reactive protein levels were higher in the lipid-rich plaque group. In patients with typical symptoms, unstable angina was more commonly observed in the lipid-rich plaque group. No significant differences in low density lipoprotein, pre-dilatation balloon specifications, pre-dilatation pressure, or stent specifications were observed. Stent release pressure in the lipid-rich plaque group ((1130.16±202.04) kPa), was significantly lower than that observed in the fibrous plaque group ((1240.61±193.29) kPa, P = 0.009).

CONCLUSIONSofter, lipid-rich plaques exhibit lower dilation resistance during stenting in PCI patients.

Objective To explore the application effect of Interactive continuing nursing intervention model with three subjects and two tracks,which is based on internet and applied to chronic heart failure patients.Methods During January 1 to December 30,2017,110 chronic heart failure patients,who were going to discharge from the Second People's Hospital of Guangdong Province,were selected for this research.Participants were equally divided into control group and observation group with random number table with 55 cases each.Participants were adopted conventional medication and traditional care,while patients in control group were given extra interactive continuing nursing intervention with three subjects and two tracks,which was relied on internet-based cardiovascular disease management platform.Comparing patients' scores of life quality,self-care ability,anxiety and depression degree before intervention and that in 6 months after intervention with Minnesota Living with Heart Failure Questionnaire (MLHFQ),Self Care of Heart Failure Index (SCHFI),Self-rating Anxiety Scale(SAS)and Hamilton Depression Scale (HAMD) respectively.Moreover,6 minute walk test was conducted,simultaneously,the incidence of cardiovascular events was calculated respectively before intervention,3 months after intervention and 6 months after intervention.Results It showed that total scores of MLHFQ,SCHFI,SAS and HAMD for patients in observation group before intervention were (49.05 ± 4.39),(101.57 ±21.04),(58.3 ± 5.2) and (40.1 ± 3.5) points respectively while that for patients in observation group after 6 months intervention were (43.03 ± 6.85),(123.17 ± 18.23),(42.3 ± 4.2) and (24.4 ± 4.3) points respectively.The difference was statistically significant (t =5.49-20.60,all P ＜0.01).In comparison,intervention effect of observation group was better than that of control group,although,the SAS scores of the control group were statistically significant.Furthermore,after intervention,the difference of MLHFQ,SCHFI,SAS and HAMD scores were statistically significant(t =3.48-17.79,all P ＜0.01).Moreover,6 months after intervention,6 minute walk test evaluation showed that there was statistical significance between observation group and control group (~=8.11,P ＜0.05).Besides,The death rate in observation group was lower than that in control group after 6 months intervention (~=6.30,P ＜0.05).Meanwhile,readmission rate after 3 months and 6 months indicates that there was statistical significance between observation group and control group(x2=5.25,6.30,P ＜0.05).Conclusions Interactive nursing intervention model with three subjects and two tracks which based on internet is able to enhance chronic heart failure patients' self-care ability and life quality,decrease the incidence of cardiovascular events and negative emotion of patients.

OBJECTIVETo investigate the clinical characteristics of intracranial hematoma and the mechanism involved in its rapid natural resolution.

METHODSSeventeen cases of intracranial hematoma with typical clinical and CT manifestations were retrospectively studied.

RESULTSIntracranial hematoma was found obviously decreased in size within 72 h after its occurrence in 8 cases. The rest 9 cases presented complete resolution.

CONCLUSIONSRapid natural resolution of acute epidural hematoma is mostly found in teenagers and the resolution is correlated with cranial fracture at the hematoma site. As for acute subdural hematoma, its rapid resolution is associated with the transfer of cerebrospinal fluid toward subdural space, the lavage effect, and the compression caused by the increased intracranial pressure or the space left resulting from redistribution of the hematoma in brain atrophy.

OBJECTIVETo optimize the condition for inducing the differentiation of 3T3-L1 preadipocytes into adipocytes and study the expression of PTEN tumor suppression gene in this process, aiming to understand the regulatory role of PTEN in normal adipocyte differentiation and collect laboratory evidence for developing drugs targeting PTEN.

METHODSThe differentiation of 3T3-L1 preadipocytes cultured in high-glucose DMEM were induced according to 2 protocols with different combinations of dexamethasone, isobutylmethylxanthine (IBMX) and insulin, and the resultant adipocytes were identified by oil red O staining. The total proteins of 3T3-L1 were extracted and analyzed by Western blotting, and PTEN homology between mice and human was analyzed by bioinformatic method.

RESULTSFor optimized 3T3-L1 differentiation, 3T3-L1 cells were initially induced with the combination of 1 micromol/L dexamethasone, 0.5 mmol/L IBMX and 5 microg/ml insulin for 48 h, followed by treatment with 5 microg/ml insulin in 4.5 g/L glucose DMEM for 48 h, which resulted in high differentiation rate of 3T3-L1 cells (up to 90% on the 10th day) with unified morphology and size. PTEN expression varied quantitatively in the process of differentiation, especially low on the 12th day as compared with those measured on days 4, 6 and 9. The mice PTEN mRNA shared 96% homology and PTEN amino acid 100% homology with their human counterparts.

CONCLUSIONEndogenous PTEN expression is down-regulated during 3T3-L1 differentiation, suggesting that PTEN may enhance insulin sensitivity and promote adipogenesis under physiological conditions.

OBJECTIVETo investigate the efficacy and feasibility of duodenojejunal bypass(DJB)on non-severe obese patients with type 2 diabetes mellitus(T2DM).

METHODSThe body mass index (BMI), fasting plasma glucose(FPG), 2h-postprandial plasma glucose(2hPG), fasting insulin(F-ins), fasting c-peptide(F-CP), glycated hemoglobin and hypoglycemic agents dose changes were tested in 7 patients with non-severe obese T2DM undergoing DJB, preoperatively and within 24 weeks after surgery during the follow-up. Data were collected and the clinical outcomes of T2DM were analyzed.

RESULTSIn 7 cases of non-obese T2DM who underwent DJB, one patient was weaned off hypoglycemic agents with normal FPG, 2hPG and HbA1c postoperatively. Five required significantly lower dosage. No significant improvement in 1 case. Complete remission rate of hyperglycemia was 1/7, effective rate was 6/7, and effective rate of HbA1c was 5/7. No significant changes in BMI were observed between the preoperative and postoperative phases.

CONCLUSIONPlasma glucose level can be markedly reduced by duodenojejunal bypass in non-obese T2DM, independent of weight loss, and the mechanism remains unclear.
