目的 了解医务人员临床工作中血源性职业暴露的情况、暴露后的心理健康状况及其影响因素,采取干预措施,保障医务人员身心健康。方法 对医院2013年1月—2017年12月上报的79例血源性职业暴露者,在1个月内进行现状调查,同时采用自填式问卷症状自评量表(SCL-90)对调查对象进行调查,对其暴露后的心理影响程度进行评估。结果 医务人员在发生血源性职业暴露后其中躯体化因子、人际关系敏感因子、抑郁因子、焦虑因子在职业暴露前后的比较及与未发生职业暴露的医务人员相比较,均有不同程度的提高,差异均有统计学意义(P<0.001)。单因素分析显示影响血源性职业暴露后医务人员的心理健康状况的因素有年龄、职业、工龄、既往发生职业暴露史和患者患传染病种类(P<0.05)。其中年龄在21~25岁年龄的医务人员的得分较高,职业为医生和陪护工人的得分较高,工龄在1~5年的得分较高,既往发生过职业暴露的医务人员得分较高,患者患传染病类型为梅毒及暴露源不明的得分较高。结论 医务人员在发生血源性职业暴露后,其心理健康状态可受到较大影响;工龄、既往发生职业暴露史和患者患传染病种类是医务人员发生血源性职业暴露后心理状况健康的独立影响因素。医院管理者在重视预防及减少职业暴露的同时,更应关注血源性职业暴露后的心理变化,及时提供心理支持和医疗帮助。

Objective To explore the related factors affecting the re-donation of the first apheresis platelet donors, and to provide a basis for the retention strategy. Methods A total of 13 899 blood donors who successfully donated apheresis platelets for the first time in Guangzhou Blood Center from January 1, 2016 to December 31, 2016 were selected as subjects. The correlation among gender, age, education level, adverse reactions of blood donation and whether platelet collection was re-donated in the next year was analyzed. Results Re-donation rate of male blood donors (10.68%) was higher than that of female blood donors (8.94%). The difference was statistically significant (P<0.01). Re-donation rate of blood donors aged 18～25 was the highest 12.86%, and that of 46～60 was the lowest 6.46%. The difference was significant (P<0.001). Re-donation rate of high school or vocational college blood donors was the highest 11.23%. The lowest re-donation rate was 8.94% in the undergraduate group or above, and the difference was statistically significant (P< 0.001). The re-donation rate of donors without adverse reactions (10.37%) was higher than that of donors with adverse reactions (5.56%). The difference was statistically significant (P<0.01). Conclusion Male, younger, less educated and no adverse reactions to blood donation are more willing to return to donate platelet again. Targeting these donors for reserve measure will conducive to the establishment of a fixed platelet donor team.

Objective To study the efficacy and its influence on anal function of RPH combined with external ligation and internal ligation in the treatment of severe mixed hemorrhoids. Methods 100 patients with severe mixed hemorrhoids admitted to our hospital from May 2017 to May 2018 were selected as research subjects. They were randomly divided into the study group and the control group, 50 cases in each group. The control group was treated with PPH, and the study group was treated with RPH combined with external stripping and internal ligation. The therapeutic effect and operation related indexes of the two groups were compared, and the postoperative anal function scores were observed. Results The clinical efficacy of the study group was higher than that of the control group (P<0.05), and the intraoperative bleeding volume, operation time and hospitalization time of the study group were lower than that of the control group (P<0.05). The anal function scores such as dry stool, gas, dilution, lifestyle changes and padding requirement in the study group were lower than those in the control group (P<0.05). Conclusion RPH combined with external stripping and internal ligation is better than PPH alone in the treatment of severe mixed hemorrhoids.

Objective To investigate the effect on intestinal mucosal barrier dysfunction (IBF) of Xuebijing injection mediated by Toll-like receptor 4 (TLR4) signal pathway in rats of severe acute pancreatitis (SAP). Methods 24 Sprague Dawley (SD) rats were randomly divided into Sham group (n=8), control group (n=8) and treatment group (n=8). The SAP model was established by retrograde injection of 4.5% sodium taurocholate into the biliopancreatic duct in control group and treatment group, while control group was injected with the same amount of saline. In treatment group, Xuebijing injection (3 mL/kg) was injected via tail vein after 3h of modeling. All rats were monitored and sacrificed after 24 hours of modeling. Samples of pancreas and intestine were collected for pathologic determination. A fluorescent RT-PCR was used to determine the expression of TLR4 and NF-κB of small intestine. The serum levels of TNF-α, IL-6, amylase (AMS) and diamine oxidase (DAO) were measured by using ELISA. All parameters of three groups were compared. Results The expression of TLR4 and NF-κB of small intestine in control group and treatment group were higher than it in control group (P<0.05), as well as the serum levels of TNF-α, IL-6, AMS and DAO (P<0.05). The expression of TLR4 and NF-κB of small intestine in treatment group were lower than it in control group (P<0.05), as well as the serum levels of TNF-α, IL-6, AMS and DAO (P<0.05). Conclusion Xuebijing injection may not only reduce the expression of TLR4 and NF-κB of small intestine, but also alleviate the inflammation reaction of small intestine by interfering with TLR4 signal pathway, which may have a protective effect on intestinal mucosal barrier in SAP rats.

目的 探讨腹腔镜下输卵管积水既往手术史对血清AMH和卵巢储备功能的影响。方法 选择2016年1月—2016年12月期间在中山市博爱医院生殖内分泌科就诊拟行体外受精—胚胎移植术患者,按照既往的输卵管积水的不同处理方式将患者分为腹腔镜下双侧输卵管切除术组(A组,n=52)、腹腔镜下双侧输卵管开窗术组(B组,n=71)、双侧输卵管阻塞或通而不畅而无积水组(C组,n=96),比较各组在促排卵首日AMH、以及AFC、FSH、LH、E2、孕酮的差异,比较各组Gn治疗时间和用量,以及注射HCG日的成熟卵泡数的差异。结果 A组的AMH、LH低于B组和C组(P<0.05),而B组和C组间AMH、LH差异无统计学意义(P>0.05)。A组AFC水平低于C组(P<0.05),而E2水平高于C组(P<0.05)。A组的FSH高于B组和C组(P<0.05),B组和C组间FSH差异无统计学意义(P>0.05)。三组间孕酮差异无统计学意义(P>0.05)。A组的注射HCG日的成熟卵泡数低于B组和C组(P<0.05),而B组和C组间成熟卵泡数差异无统计学意义(P>0.05)。A组Gn用量高于B组和C组(P<0.05),而B组和C组间Gn用量差异无统计学意义(P>0.05)。三组间Gn治疗时间差异无统计学意义(P>0.05)。结论 通过AMH等指标检测,腹腔镜输卵管切除术会降低患者的卵巢储备功能,而开窗术则影响相对较小,对有生育要求的妇女应考虑行输卵管开窗术等方式以保护卵巢功能。

Objective To explore the stabilized total knee arthroplasty effects on early functional changes of condylar offset. Methods 121 cases of posterior stabilized total knee arthroplasty in our hospital from Jan.2013 to Jan.2016 were enrolled in the study. All patients with preoperative and postoperative posterior condylar offset records, according to the changes of femoral condylar offset were divided into A group and B group. The patients in the two groups were followed for at least 12 months, and the differences in the Osteoarthritis Index score (WOMAC), the American Knee association score (KS), HSS score and knee function were compared. Results After surgery, two patients in the anterior condylar offset changes, femoral prosthesis flexion angle, tibial angle, tibial angle difference was not statistically significant (P > 0.05). But after 1 years, the improvement of WOMAC score, HSS score and weight-bearing active flexion range in group A was better than that in group B, the difference was statistically significant (P < 0.05). Conclusions The reconstruction of the posterior condylar offset can improve the stability after total knee arthroplasty in patients with early osteoarthritis symptoms, and enhance the active flexion range of patients with weight-bearing, which has some clinical value.

目的 探讨自由体位分娩方式和传统体位分娩方式对产后盆底功能的影响。方法 2015年3月—2016年3月在广州市妇女儿童医疗中心定期产检并分娩单胎初产阴道分娩610例产妇,按分娩方式分为自由体位分娩298例为实验组,传统体位分娩312例为对照组,对两组产妇会阴损伤,产后6～8周筛查盆底肌力,探讨不同体位分娩方式对产后盆底肌力的影响。结果 实验组阴道静息压,阴道收缩压、Ⅰ类肌纤维强度、 Ⅱ类肌纤维强度、阴道收缩持续时间均较对照组有增加,差异性均有统计学意义(P<0.05)。结论 自由体位分娩方式不降低产后盆底肌力,对产后盆底有保护作用。

Objective To analyze the effects of liberal intrapartum postures on the pelvic floor function of postpartum. Methods 610 pregnant women (vaginal delivery,single birth,and head position) were classified and analyzed in Guangzhou Women and Children Medical Center from March 2015 to March 2016. All the pregnant women were mature without pregnancy complications; 298 pregnant women who adopted free posture delivery were selected as observation group,312 pregnant women who adopted traditional posture delivery were selected as control group. We counted the number of perineal injury incidence of the two group,and the pelvic floor strength of the two groups was measured after fetal birth after 6 to 8 weeks. Results We compared the vaginal resting pressure(VRP),vaginal squeezing pressure(VSP),classⅠfiber strength, class Ⅱ fiber strength and the time of vaginal contraction between the two groups. Pelvic floor muscle strength was significantly stronger in the observation group than that in the control group (P<0. 05). Conclusion There is a closely association between the different intrapartum postures and the pelvic floor function of postpartum. Adopting free posture delivery has no adverse impact on pelvic floor function of postpartum, which can protect the function of female pelvic floor.
