临床检验不合格血液标本产生原因及质量改进研究

目的:分析临床检验不合格血液标本的原因为何,研究相应的质量改进方法。方法:本课题自我院检验血液标本样本中抽取140份,其中2018年2月~2019年3月的70份命名成对照组,2019年4月~2020年3月的70份命名成试验组,前一组未进行质量改进,后一组进行质量改进,比较检验结果有何不同。结果:试验组这组的检验标本不合格率要比对照组那组的检验标本不合格率低,数据上是P<0.05的情况,即表明有统计学意义。结论:凝血反应、溶血反应、样本问题、送检失误、抗凝不全等是导致临床检验不合格血液标本的原因所在,实施质量改进可将血液标本质量提高。     

脑后部可逆性脑病综合征(PRES)的临床MR诊断

目的：探讨MR对PRES的临床诊断价值。方法应用3.0 T MR对30例PRES患者进行常规扫描，其中19例同时行MRA检查，13例行MRV检查。结果 PRES病变主要累及顶枕叶，双侧基本对称；病变主要位于脑白质内，也可累及其它部位。PRES病变的特点是呈长T 1长T 2信号，边缘不清，无明显占位效应。MRA及MRV均无异常发现。结论 MR对PRES可以作出准确诊断，对临床有重要的指导意义。

Lower body mass index and higher height are correlated with increased varicocele risk

To evaluate the anthropometric indexes in subjects with varicocele compared to controls and the incidence of varicocele in different body mass index (BMI) groups for the purpose of exploring the association between varicocele and anthropometric indexes. A comprehensive literature search was conducted by using PubMed, MEDLINE, EMBASE databases and Cochrane Library up to February 2019. A systematic review and meta‐analysis was conducted by STATA, and Newcastle–Ottawa Scale was utilised for assessing risk of bias. Ultimately, 13 articles containing seven case–control studies and six cross‐sectional studies with 1,385,630 subjects were involved in our study. Pooled results demonstrated that varicocele patients had a lower BMI (WMD = ?0.77, 95% CI = ?1.03 to ?0.51) and a higher height than nonvaricocele participants, especially in grade 3 varicocele patients. Subgroup analyses showed that normal BMI individuals had a higher risk of varicocele than obese or overweight individuals and a lower risk than underweight individuals. In conclusion, this study indicates that varicocele patients have a lower BMI and a higher height than nonvaricocele participants. Moreover, men with excess bodyweight have a lower incidence of varicocele compared to normal weight or underweight people. That is to say, high BMI and adiposity protect against varicocele and high BMI is associated with a decreased risk of varicocele.     

保妇康凝胶联合诺氟沙星治疗宫颈糜烂50例疗效观察

目的：探讨保妇康凝胶联合诺氟沙星治疗宫颈糜烂的临床效果。方法将100例宫颈糜烂患者根据随机数字表法分为观察组和对照组各50例。观察组给予保妇康凝胶和诺氟沙星联合治疗，对照组单独给予治糜灵栓治疗，比较两组患者临床症状的变化，并对临床疗效进行评价。结果观察组治愈率为86.00%，明显高于对照组的74.00%，临床症状评分改善较对照组明显，且其临床症状消失的时间短于对照组，差异均有统计学意义(P<0.05)。结论保妇康凝胶与诺氟沙星合用比治糜灵栓治疗宫颈糜烂效果更佳，且治愈时间上明显较优，值得临床上推广应用。

Clinical observation on the effect of Chinese medicine-“TCM formula” intervention on recurrence and metastasis of triple negative breast cancer

ObjectiveThis study used a prospective cohort study to observe the effect of triple-negative breast cancer on the 2-year disease-free survival rate with or without “TCM formula”.MethodsFrom November 1 st, 2016, the first patient was enrolled in the cohort study. A total of 356 patients were enrolled on January 30, 2019. Among them, 154 cases were followed up for 2 years. During the follow-up, there were 6 cases of shedding, so 6 cases were affected. A total of 148 cases were included in the analysis, including 73 in the exposed group and 75 in the non-exposed group. The exposed group was given “TCM formula” on the basis of standardized treatment, and the non-exposed group was treated with simple triple-negative breast cancer. The two groups visited each of the three months. The interview included safety examination (hematology and imaging). The endpoint was the difference in 2-year invasive disease-free survival between the exposed and non-exposed groups and the safety of the “TCM formula”.ResultsThere were 6 cases of shedding during the experiment and the shedding rate was 3.9 %. The 2-year rate of invasive disease-free survival in the exposed team was 88.7 % and the non-exposed group was 82.5 %. Logistic multivariate regression analysis predicted that “TCM formula” could reduce the disease-related recurrence and metastasis rate by 11 % (OR = 0.89, 95 % CI 0.37−0.956, P＜0.05). Through K–M survival analysis, TNBC patients with age ≤35 years and regional lymph node stage N1 may be the benefit group of “TCM formula”(P＜0.05). During the study, the incidence of total adverse events was 8.2 % in the exposed group, mainly manifested as stomach discomfort, diarrhea, and hepatocyte damage.Conclusion1. In the exposed group, the two-year rate of invasive disease-free survival increased by 6.2 % compared with the non-exposed group(P＞0.05). 2. According to K–M survival analysis, TNBC patients with age ≤35 years and regional lymph node metastasis to N1 may be potential beneficiaries of “TCM formula”. 3. “TCM Formula” is safe and tolerable to most patients.
