目的 探讨特发性肺纤维化(IPF)患者和结缔组织病相关性纤维化间质性肺疾病(CTD-fILD)患者急性加重(AE)的短期内死亡的危险因素。方法 回顾性分析2017年10月—2019年9月在深圳大学和广州医科大学附属第一医院住院的25例 AE-CTD-fILD和26例AE-IPF患者临床信息,Kaplan-Merier法对两组患者进行生存分析,Cox回顾分析年龄、性别、吸烟、白细胞总数、C反应蛋白、红细胞沉降率及肿瘤指标在急性加重患者死亡中的作用。结果 与AE-CTD-fILD比较,AE-IPF患者组男性比例、年龄、吸烟比例较高,红细胞沉降率较低(24/26 vs 10/25,P<0.001;63.77±9.97 vs 58.00±10.32,P=0.048;16/26 vs 9/25,P=0.02;28.07±29.45 vs 64.35±40.34,P=0.002 );90天内,26例AE-IPF患者11例死亡,25例AE-CTD-fILD患者5例死亡,死亡率无明显差异(42.3% vs 20%,P=0.073);Cox回归分析显示,白细胞计数是AE-IPF和AE-CTD-fILD患者的死亡危险因素(HR=1.305,P=0.001;HR=1.529,P=0.009);CA15-3是AE-IPF患者死亡危险因素(HR=1.015,P=0.005)。结论 急性加重IPF和CTD-fILD患者短期内死亡风险相似,白细胞计数及外周CA15-3水平可能是肺纤维化急性加重患者短期内死亡的危险因素。

Objective To explore the risk factors for acute exacerbation (AE) in patients with idiopathic pulmonary fibrosis (IPF) and connective tissue disease associated with fibrotic interstitial lung disease (CTD-fILD). Methods We retrospectively reviewed 25 patients with AE-CTD-fILD and 26 patients with AE-IPF, and Kaplan-Merier was used to analyze the survival of the two groups of patients. The impact of age,gender, smoking,WBC,CRP,ESR and tumor markers on acute exacerbation death were performed by Cox regression analysis. Results The AE-IPF patients had a higher proportion of men,age and smoking,and a lower ESR compared with AE-CTD-fILD patients(24/26 vs 10/25,P<0.001;63.77±9.97 vs 58.00±10.32,P=0.048;16/26 vs 9/25,P=0.02;28.07±29.45 vs 64.35±40.34,P=0.002 ). 11 cases of 26 patients with AE-IPF and 5 cases of 25 patients with AE-CTD-fILD died within 90 days, Log-rank tests showed patients with CTD-fILD had similar mortality rate compared with IPF patients after AE(42.3% vs 20%,P=0.073). The WBC count was negatively correlated with survival and the independent predictors for patients with AE-IPF and AE-CTD-fILD after adjusting for other clinical variates in Cox regression models(HR=1.305,P=0.001;HR=1.529,P=0.009). CA15-3 may be a risk factor for death of AE-IPF patients(HR=1.015,P=0.005). Conclusion AE-CTD-fILD and AE-IPF were associated with similar poor short-term survival, WBC count and plasma CA15-3 may be the independent survival predictors respectively for patients with acute exacerbation of pulmonary fibrosis in short term.

Objective To analyze the expression of O6-methylguanine-DNA methyltransferase (MGMT) and DNA topoisomerase II (Topo II) genes in human brain gliomas and its influence on the chemosensitivity. Methods A total of 80 fresh human brain glioma specimens resected by craniotomy and 30 normal brain tissues resected by craniocerebral operation for traumatic brain injury or decompression for cerebral hemorrhage during the period from April 2012 to June 2017 were collected. The expression of MGMT and Topo II genes in the two kinds of specimens was detected by immunohistochemical method, and the influence on chemosensitivity was analyzed through brain glioma U251 and U87 cell culture, in vitro drug (temozolomide) intervention and Transwell invasion in vitro. Results There was a significant difference in the expression of MGMT and Topo II genes in glioma specimens and normal brain tissues (P<0.05). The positive expression rates of MGMT gene in the two kinds of specimens were 63.75% and 3.33% respectively while the positive expression rates of Topo II gene were 55.00% and 0.00%, respectively (P<0.05). Both of MGMT and Topo II genes were displayed in the nucleus as positive staining. There was no significant difference in transmembrane cell count of U251 and U87 cells between the experimental group given drug intervention in vitro and negative control group without drug intervention before the intervention (P>0.05). However, the transmembrane cell count of U251 and U87 cells in the experimental group after intervention was higher than that in the negative control group (P<0.05). After intervetion, U251 and U87 cells were with stronger invasiveness in the experimental group. Conclusion The positive expression rates of MGMT and Topo II genes are high in human brain glioma specimens. They may be involved in promoting glioma cell invasion, affecting tumor chemosensitivity.

Objective To explore the changes of platelet, white blood cell and red blood cell counts of long-term platelet blood donors. Methods A retrospective study was conducted on 849 platelet blood donors who donated for the first time and continuously donated amounts to 10U plateletor or more from January 1, 2016 to September 30, 2018.The paired t test of the same group was used to evaluate the changes of platelet, red blood cell and white blood cell counts between the first time and the last time donation during the study period. Ordinal multinomial logistic regression was conducted to analyze the effects of platelet donation on the peripheral blood cell count of the donor during the survey. Results Paired t-test result showed that there was a increase in PLt (t=-8.58, P<0.000 1);a decrease in WBC(t=5.348, P<0.000 1); and no significant change in RBC (t=0.515, P=0.607).The results of ordinal multinomial logistic regression analysis showed that the change in PLt had no relationship with age, sex, and interval between the first and last blood donation, P>0.05. Compared with donors who donated 41U or above,the possibility of an increase in platelet count was relatively small for those who donated 30U or below(platelet donation amount 10~20U,χ²=13.737,P<0.000 1;platelet donation amount 21～30U,χ²=7.491,P=0.006). There was no relationship between age, gender, and blood donation interval and WBC changes, P>0.05. Compared with donors who donated 41U or above, WBC was more likely to increase for those who donated 10～20 U (OR=1.720, 95%CI=1.136~2.605, P=0.010).RBC changes had nothing to do with age, gender and platelet donation amount of the blood donor, P> 0.05; the longer the interval between the first and last blood donation took, the more likely the red blood cell count increased, (OR=1.005, 95%CI=1.000~1.009, P=0.030). Conclusion For continuous platelet donors with platelet donation intervals of no less than 2 weeks, platelet donation amount will affect the peripheral blood counts,and all the blood conuts are within the normal range.

Objective Our study is aim to investigate the possible relationship of seminal elastase, on semen parameters and DNA fragmentation in male patients of recurrent pregnancy loss (RPL) between June 2019 and January 2020. Methods The patients included 80 male patients of RPL couple and 25 male patients from couples with clinical pregnancy through in vitro fertilization due to the female tubal factor. The semen samples were used to determine the seminal elastase, computed assisted semen analysis, sperm dispersion test and sperm morphology analysis. Results Compared to the control group, the levels of seminal elastase was increased in the RPL group. The RPL group was divided into the normal group (Elastase<600 ng/mL) and abnormal group (Elastase ≤ 600 ng/mL).The abnormal group exhibited the lower percentage of progressive sperm (P=0.002) and normal morphology (P=0.009),but higher precentage of DNA fragmentation (P=0.002). Meanwhile, the seminal elastase was positively associated with DNA fragmentation (r=0.36,P=0.001), but was inversely associated with the sperm motility (r=-0.43,P<0.001) and normal morphology (r=-0.39,P<0.001). Conclusion Our study may unveil the possible effects of the seminal elastase on the semen parameters and DNA fragmentation in the male patients of RPL couples. Further studies should put more emphasis on the silent genital tract inflammation of the patients.

Objective To explore the correlation in serum uric acid level and bone mineral density (BMD) and fracture rate in male patients with type 2 diabetes mellitus (T2DM). Methods 192 cases of male patients with T2DM in Guangzhou First People's Hospital were selected in this study.BMD was measured by bone density machine. The patient's age, diabetes course and BMI were recorded. Fasting blood glucose, glycated hemoglobin (HbA1c), liver and kidney function, blood uric acid, blood lipid, alkaline phosphatase, 25 hydroxyvitamin D3 levels were measured, and the correlation between BMD and other indicators was analyzed. Results The serum uric acid level,lumbar and right femoral neck BMD in the osteoporosis group were lower than those in the normal and low bone mass groups (P<0.05). Serum uric acid was positively correlated with BMD values of lumbar spine and right femoral neck in male patients with type 2 diabetes (P<0.01). BMD value of right femoral neck was negatively correlated with age and positively correlated with fasting blood glucose (P<0.05). Multivariate logistic regression analysis showed a significant negative correlation between serum uric acid and clinical fractures in male patients with type 2 diabetes (model 1). When the model was adjusted for age, fasting blood glucose, ALP and other factors, serum uric acid levels were still associated with clinical fractures (model 2). When the BMD values of the lumbar spine and the right femoral neck were further included (model 3), the results were not statistically significant. Conclusion Slightly higher blood uric acid levels may help to reduce the incidence of OP and fracture rate in male patients with T2DM.

Objective To compare the short-term clinical effects difference between analgesic tincture and topical nonsteroidal anti-inflammatory drugs (NSAIDs) in the treatment of lateral epicondylitis (LE). Methods 60 cases of LE patients were randomly divided into an analgesic tincture group (n=30) and a NSAIDs group (n=30). Analgesic tincture was chosen for the analgesic tincture group and topical ketoprofen gel for the NSAIDs group to treat LE. Two groups were treated continuously for 3w, 3 times/day. Clinical results of each drug were followed-up at the time point of 3w, 6w and 12w after usage. Observational indexes included the visual analogue scale (VAS), disabilities of the arm, shoulder and hand questionnaire (DASH) and pain-free grip strength (PFGS). The inter-group difference of VAS (at activity), VAS (at rest), DASH score and PFGS were compared subsequently. Results No difference of the VAS (at activity), VAS (at rest), DASH score were ascertained (P> 0.05) between groups. Inter-group difference of PGFS was also not discerned at the time points of pre-treatment and 3 weeks and 6 weeks (P=0.91, P=0.42, P=0.13) post-treatment. However, PFGS of the analgesic tincture group was found to be higher than that of the NSAIDs group (P=0.02) after 12 weeks post-treatment. Conclusion Effect of analgesic tincture in releasing pain is almost the same to that of tropical NSAIDs, but a better effect in improving muscle strength.
