Objective:To explore the application value of combined detection of troponin I (cTnI) and creatine kinase isoenzyme mass (CKMBmass), interleukin-6 (IL-6) and fibrinogen degradation products (FDP) in the diagnosis and treatment of acute myocardial infarction (AMI).Methods:A total of 102 AMI patients in Wanbei Coal Power Group General Hospital from July 2019 to June 2020 were selected as the AMI group. In addition, 60 patients diagnosed with chest pain (CP) and chest distress (CD) during the same period were selected as the CPCD group, and 60 healthy patients were selected as the healthy control group. The levels of cTnI, CKMBmass, IL-6 and FDP in the peripheral blood of the three groups were compared, and the receiver operating characteristic (ROC) curve was used to evaluate the diagnostic value of cTnI, CKMBmass, IL-6, and FDP. The AMI group was given thrombolytic therapy. The clinical data of patients with different curative effects, the trend of changes in peripheral blood cTnI, CKMBmass, IL-6 and FDP levels before and after treatment were compared, and the relationship between the above indicators and clinical indicators and curative effects were analyzed.Results:The levels of peripheral blood cTnI, CKMBmass, IL-6 and FDP in the AMI group were higher than those in the CPCD group and the healthy control group, and the levels of peripheral blood cTnI, CKMBmass, IL-6 and FDP in CPCD group were higher than those in the healthy control group ( P<0.05). The area under the curve (AUC) values of cTnI, CKMBmass, IL-6 and FDP in the combined diagnosis of CPCD and AMI were 0.898 and 0.926, respectively, which were higher than those of single diagnosis. The time from onset to thrombolysis, infarct location, diabetes, diastolic blood pressure (DBP), systolic blood pressure (SBP), left ventricular end systolic volume (LVESV), left ventricular end systolic diameter (LVESD), left ventricular end diastolic volume (LVEDV), left ventricular end diastolic diameter (LVEDD), left ventricular ejection fraction (LVEF) on admission of effective patients and ineffective patients were statistically significant ( P<0.05). The levels of peripheral blood cTnI, CKMBmass, IL-6, and FDP of effective patients were lower than those of ineffective patients when they were admitted to the hospital and 6, 12, 24, 48, and 72 h after treatment ( P<0.05). The peripheral blood cTnI, CKMBmass, IL-6, and FDP on admission were positively correlated with DBP, SBP, LVESV, LVESD, LVEDD, LVEDV, and was negatively correlated with LVEF ( P<0.05). Multiple linear stepwise regression analysis showed that after the onset to thrombolysis time, infarct location, smoking, diabetes, SBP, DBP, LVESV, LVESD, LVEDD, LVEDV, LVEF and other factors at admission were controlled, the levels of peripheral blood cTnI, CKMBmass, IL-6, FDP were still significantly related to the efficacy ( P<0.05). Conclusions:The peripheral blood cTnI, CKMBmass, IL-6, and FDP are all abnormally expressed in AMI patients. Combined detection has clinical significance for the diagnosis and treatment of AMI.

Objective To investigate the prevalence and spectrum of β-thalassemia mutations in C, uangdong province, and provide a reference for prenatal diagnosis and genetic counseling in this population. Methods Three thousand two hundred and forty-seven blood samples were randomly selected from Guangzhou and 2984 blood samples from Shenzhen from January in 2005 to January in 2009. PCR and reverse dot blot hybridization (RDB) were adopted for detection of β-thalassemia mutations in Guangzhou and Shenzhen city. Results Seven hundred and fifty-one individuals in Guangzhou were found to have β-hemoglobin gene mutations, the detection rate was 23.13%(751/3247); 10 different mutations were identified, namely CD41-42(-TCTT), IVS-Ⅱ-654(C→T), -28(A→G), CDI7(A→T), CD71-72(+A), 13E, IVS-I-1(G→T), CD43(G→T), -29(A→G), CDI4-15(+G), which accounted for 42.53% (336/790) ,25.19% (199/790), 12.66% (100/790), 10.89% (86/790) ,3.29% (26/790), 2.15%(17/790), 1.27%( 10/790), 1.14%(9/790) ,0.51%(4/790) ,0.38%(3/790), respectively; the most common mutation was CD41-42(-TCTT), which accounted for 42.53%(336/790). In Shenzhen, 179 individuals were found to have β-thalassemia mutations, the detection rate was 6.00% (179/2984); 8 different mutations were identified excluding CD43 (G→T) and CD14-15 (+G); the most common mutation, however, was IVS-lI--654(C→T), which accounted for 40.44% (74/183). Conclusions The β-thalassemia mutations in Guangdong province are not only frequent, but also obviously heterogeneous, and the mutations differ from region to region. CD41-42 (-TCTT),ⅣS-Ⅱ-654(C→T), -28(A→G), CD17(A→T) were the 4 predominant mutations.

Objective To study the effect of antiapoptosis factors PED/PEA-15 and XIAP on prostate cancer cells(PC-3)apoptosis.Methods The expressions of XIAP and PED/PEA-15 in prostate cancer cells(PC-3)were respectively assayed using the RT-PCR technique.XIAP and PED/ PEA-15 specific siRNA vectors were designed and constructed and then were transiently cotransfected into PC-3 cells under induction of liposome.The effects of siRNA vectors on PED/PEA-15 and XIAP transcription were assayed by RT-PCR technique,and the effect of XIAP and PED/PEA-15 on cancer cell apoptosis were determined by flow cytometry and microscope observation.Results PED/PEA- 15 and XIAP were both highly expressed in PC-3 cells.Enzyme digestion analysis and DNA sequencing confirmed that the PED/PEA-15 and XIAP-specific siRNA expression vectors were constructed successfully.The designed siRNA sequences of PED/PEA-15 and XIAP could specifically inhibit their transcription.The PC-3 cells which were cotransfected with PED/PEA-15 and XIAP- specific siRNA vectors were more sensitive to doxorubicin.The apoptosis rate of cotransfected cells was significantly increased.Conclusions PED/PEA-15 and XIAP might be involved in the development of prostate cancer.

RESULTSGood results were achieved in all the patients with primary healing. No flap necrosis happened. The result was satisfactory.

CONCLUSIONSWith bilateral subdermal soft tissue "C" flaps and " lambda" flap, nasal base depression deformities and lip whistle deformities can be corrected. It is an ideal method for correction of deformities after BCCL repair.

Armillariella tabescens EJLY2098 was capable of secreting p-mannanase by konjac inducement. A 34 orthogonal design was applied to determine the optimum medium of inducing mannanase by Armillariella tabescens EJLY2098. The results suggested that Armillariella tabescens EJLY2098 secreted the high-activity enzyme in the optimum medium, which was composed of 2% konjac, 1% peptone, 25% potato juice,0.3% KH2PO4,15% MgSO4?7H2O, 0.01% VitB1. Purified by DEAE-anion exchange chromatography, two eluting peaks (P1 and P2) with the p-mannanase activity were obtained, and one of them (named?-mannanase P2) was a single band by the SDS-PAGE, and the molecular weight of?-mannanase P2 was 78. 9kDa. The isoelectric point of?-mannanase P2 was estimated to be 4.0-4. 1. The optimum activity for the enzyme was found at 60℃and pH4. 0 - 6. 0, and the enzyme was stable between pH4. 5 - 6. 0. The activity of?-mannanase P2 were enhanced by Na+ and Ba2+ . This?-mannanase can be used in feed industy. a new fungi secreting?-mannanase was obtained, providing an important base for cloning mannanase gene and constructing recombin microbe expressing?-mannanase .

The HPLC fingerprint determination method of Jinzhen oral solution was established to provide a new method for quality control of Jinzhen oral solution. RP-HPLC was used for phenomenex Luna C18 (4.6 mm x 250 mm, 5 μm) chromatographic column, with 0.1% H3 PO4 water solution and acetonitrile as the mobile phase for gradient elution. The detection wavelength was 280 nm. HPLC fingerprint of Jinzhen oral solution was established to identify 17 common peaks in Jinzhen oral solution. The similarity of fingerprints of 10 batches of finished products was more than 0. 90. The established HPLC fingerprint has a better precision, reproducibility and stability, and can be applied in quality control of Jinzhen oral solution.
