ABSTRACT
Objective To investigate the level change of interleukin-37(IL-37) and its clinical significance in the patients with chronic kidney disease(CKD) and nephrotic syndrome(NS) .Methods 57 cases of CKD (CKD group) and 13 cases of NS (NS group) in the Affiliated Donghua Hospital of Sun Yat-sen University from September to November 2016 were selected .The CKD group was redivided into the CKD stage 1 ,stage 3 and stage 5 groups .At the same time 22 individuals undergoing physical examina-tion were selected as the healthy control group .The ELISA sandwich method was adopted to detect the plasma IL-37 level .Then the detection results were statistically analyzed .Results The level of plasma IL-37 in the CKD group and NS group was significant-ly higher than that in the healthy control group ,the difference was statistically significant (P<0 .01);the level of plasma IL-37 had no statistical difference among the CKD stage 1 group ,CKD stage 3 group and CKD stage 5 group(P>0 .05);the plasma IL-37 lev-el after treatment in the CKD group and NS group was decreased compared with before treatment ,the difference was statistically significant(P<0 .01);the plasma IL-37 level in CKD patients was positively correlated with the WBC and lymphocyte cells levels . Conclusion The patients with CKD and NS have high level expression of plasma IL-37 ,which might have good auxiliary diagnostic value for CKD and NS .
ABSTRACT
Objective To investigate the treatment outcome of modified intracytoplasmic sperm injection (ICSI)using zona pellucida(ZP)-bound sperm.Methods 82 patients with less,weak,abnormal sperm disease who were conformed to ICSI,were divided into traditional ICSI group and the group of modified ICSI using ZP-bound sperm according to ICSI case number.The results of normal fertilization rate,cleavage rate,high-quality embryo rate, planting rate,clinical pregnancy rate and early abortion rate were compared.Results The women's age,the sterility year,mature egg rate,normal fertilization rate,cleavage rate in the two groups had no statistically significant differ-ences (all P>0.05).The planting rate and clinical pregnancy rate of the observation group (46.6%,63.3%)were higher than those of the control group(38.5%,53.6%),but there were no statistically significant differences(all P>0.05).The using embryo rate and high-quality embryo rate of the observation group (73.9%,51.0%)were signifi-cantly higher than those of control group(65.8%,38.6%),the differences were statistically significant(χ2 =5.84,χ2 =11.6,all P<0.05).Conclusion Modified ICSI using ZP-bound sperm can effectively improve the embryos quality in ICSI.
ABSTRACT
Objective To investigate the effects of sperm DNA fragmentation (SDF)and sperm morphology on the fertilization and embryo development in ICSI.Methods SDF and sperm morphology were detected in the meanwhile of taking eggs in 1 45 ICSI treatment cycle.On the basis of SDF index (DFI)divided into group A (DFI≤30%)and group B (DFI >30%).According to the normal sperm morphology divided into group C (NMSR≥4%), group D (1 %≤NMSR 30% and NMSR 0.05).(2)The normal fertilization rate was statistically significant in group C,group D,group E (χ2 =34.5,65.8,11 .8,all P 0.05).(3 )The normal fertilization rate,embryo utilization rate,good quality embryo rate,implantation rate and clinical pregnancy rate in group F were significantly higher than those in group G,and normal fertilization rate,embryos utilization rate,good quality embryo rate had statistically significant differences (χ2 =37.5,1 1 .0,4.3,all P <0.05). Conclusion Sperm abnormal morphology has negative effect on fertilization,and the high DNA fragments have negative effects on fertilization and embryo development.
ABSTRACT
Taxillus chinensis,belonging to hemiparasitic herbal medicine and featuring its wild host range,is used for relief from rheumatic conditions,reinforcement of liver and kidney,strengthening of tendon and bone,and prevention of abortion.It showed that host trees presented significant impacts on the quality of Taxillus chinensis in the modern researches.In this study,both domestic and foreign published articles over Taxillus chinensis from various host trees were reviewed to summarized its herbalogy,chemical constituents,toxicity,and pharmacological action.In regard to the influences on the quality of medicinal materials,ideas and references for the quality control of Taxillus chinensis were provided by analyzing the quality of Taxillus chinensis impacted by hosts.
ABSTRACT
Objective To explore the extensively drug resistant mechanism and clinical treatment strategy of Klebsiella pneu-moniae .Methods The isolate was identified by Vitek2 Compact System.Antimicrobial susceptibility testing was conducted by Kirby-Bauer method.KPC-2 carbapenemase was detected by modified Hodge test.The gene encoding KPC-2 carbapenemase was amplified by polymerase chain reaction (PCR)and then sequenced.Results The strain was resistant to all antibiotics used in routine antimicrobial susceptibility testing except amikacin.Modified Hodge test showed positive result.KPC-2 gene was detected by PCR.The sequence was consistent with that of 11844849 in GenBank.After treatment for one month,no exten-sively drug resistant K.pneumoniae strain was detected from the patient.Conclusions It is necessary to strengthen the monito-ring and improve the awareness of extensively drug resistant K.pneumoniae for better control of such infections.
ABSTRACT
<p><b>OBJECTIVE</b>To study the correlation of 1-deoxynojirimycin (DNJ) between Taxilli Herba parasitized in mulberry and its host-plants.</p><p><b>METHOD</b>The contents of DNJ of Taxilli Herba parasitized in mulberry and non-mulberry were determined by RP-HPLC. DNJ was extracted with 0.05 mol x L(-1) HCl, and then detected by fluorescence detector after derivatized with FMOC-Cl at pH 8.0 with borate buffer. The separation was performed on an Agilent C18 (4.6 mm x 250 mm, 5 microm) column with a mobile phase of acetonitrile-0.1% aqueous acetic acid (51: 49) at a flow rate of 1.0 mL x min(-1). The wavelength of fluorescence detector was operated at lambda(EX) = 254 nm and lambda(EM) = 322 nm.</p><p><b>RESULT</b>The linear range of DNJ was 3.72-37.2 mg x L(-1) (r = 0.999 9). The average recovery was 96.42%. The contents of DNJ in mulberry and Taxilli Herba parasitized in mulberry were 1.39-10.16 mg x g(-1) and 0.46-2.72 mg x g(-1), respectively. However, the contents of DNJ could not be detected in Taxilli Herba parasitized in non mulberry and its host-plants.</p><p><b>CONCLUSION</b>As the characteristic constituent of mulberry, DNJ was accumulated in Taxilli Herba This method can be applied to the quality control of Taxilli Herba from mulberry.</p>

Objective To understand the relationship between coagulation factors,inflammatory reaction and coronary heart disease(CHD) by analyzing the changes of fibrinogen (Fib), D-dimer (DD) ,C-reactive protein(CRP) and white blood cell (WBC) count. Methods The levels of Fib, DD, CRP and WBC were measured and compared in 91eases with CHD[ineluding 34 cases of acute myocar-dial infarction (AMI group),30 eases of unstable angina peetoris (UAP group) and 27 eases of stable angina peetoris (SAP group)] and 30 healthy controls (healthy control group). Results Plasma con-centrations of Fib, DD, CRP and WBC were the highest in AMI group, followed by those in UAP group,SAP group and healthy control group. There were statistical differences in the above parameters between AMI group and UAP group; so were between UAP group and SAP group. There was no sig-nificant difference between UAP group and healthy control group (P>0. 05). Conclusion The coagu-lation factors and inflammatory reaction are closely associated with occurrence and development of cor-onary heart disease. Four parameters (Fib,DD,CRP and WBC) can be used as adjuvant indicators of differentiating types of CHD and evaluating severity of disease.
