加强型鼻咽通气道应用于鼻腔手术后气道管理临床研究

目的研制加强型鼻咽通气道应用于五官科鼻腔手术后的气道管理。方法选取2014年1月至2015年3月行五官科鼻腔手术的患者60例,将其分为A组和B组,各30例。A组作为加强型鼻咽通气道组,术毕在膨胀止血海绵中放置加强型鼻咽通气道保留鼻腔通气;B组作为对照组,术毕采用传统单纯填塞膨胀止血海绵。通过术后24、48 h随访,对两组患者进行疼痛、睡眠质量、口干程度评分,并对其进行对比分析。结果加强型鼻咽通气道具有良好的抗压抗折性;A组患者24、48 h睡眠质量、口干程度评分均明显优于B组,差异均有统计学意义(P<0.05)。结论加强型鼻咽通气道用于五官科鼻腔手术后气道管理可增强气道管理安全性及患者舒适度。     

水针疗法联合清热祛毒汤治疗寻常型银屑病(血热证)的疗效及其作用机制分析

目的观察分析水针疗法联合清热祛毒汤治疗寻常型银屑病(血热证)的疗效及其作用机制。方法选择2018年8月—2019年7月在我院接收治疗的112例寻常型银屑病患者作为分析对象,采取随机分组的办法将其分为对照组56例和研究组56例,对照组患者采取水针疗法治疗,研究组在对照组的基础上联合清热祛毒汤治疗。比较分析2组患者的疗效;治疗前后的中医证候评分、皮肤病生活质量指数(DLQI)评分;治疗前后皮损面积、浸润、鳞屑、红斑等评分;治疗前后肿瘤坏死因子α(TNF-α)、白细胞介素6(IL-6)、血管内皮生长因子(VEGF)水平变化情况。结果研究组患者治疗总有效率89.29%明显高于对照组73.21%(P<0.05);治疗前,2组患者的中医证候评分、DLQI评分、皮损面积、浸润、鳞屑、红斑等评分及TNF-α、IL-6、VEGF等水平比较(P>0.05);研究组患者治疗后的中医证候评分与DLQI评分明显低于治疗前(P<0.05);研究组患者治疗后的皮损面积、浸润、鳞屑、红斑等评分明显低于对照组(P<0.05);研究组患者治疗后的TNF-α、IL-6、VEGF等水平明显低于对照组(P<0.05)。结论对寻常型银屑病患者采取水针疗法联合清热祛毒汤治疗的疗效显著,能有效改善中医证候表现,提高生活质量,减轻皮损程度,降低炎症反应,其作用机制可能与炎症因子水平、皮损血管增生相关。     

基于BGP、TGF-β1的表达探究蛇床子素对去卵巢致骨质疏松大鼠的作用

目的观察蛇床子素对去卵巢致骨质疏松大鼠的影响。方法选取3月龄雌性SD大鼠30只,随机分为蛇床子素组(A组)、模型对照组(B组)、假手术组(C组),各10只。A、B 2组摘除卵巢构建去势大鼠骨质疏松模型,C组仅进行手术、不摘除卵巢。造模成功后,分别给予相应药物灌胃,连续给药12周,处死。然后测量骨密度,检测治疗后血清BGP、TGF-β1、钙指标。结果B组大鼠股骨骨密度较C组明显降低(P<0.05);经12周治疗,A组股骨骨密度较B组明显升高(P<0.05)。与C组比较,B组大鼠血清中BGP含量升高、TGF-β1降低(P<0.05);与B组比较,A组大鼠血清中BGP降低、TGF-β1含量升高(P<0.05)。与C组比较,B组大鼠血清Ca水平明显降低(P<0.05);与B组比较,A组大鼠血清Ca水平明显升高(P<0.05)。差异均有统计学意义。结论蛇床子素能够有效通过调节大鼠体内激素分泌改善去卵巢大鼠的骨代谢异常,提高骨密度,对骨质疏松症起到一定的防治作用。     

Subscapularis Transthoracic Versus Posterolateral Approaches in the Surgical Management of Upper Thoracic Tuberculosis: A Prospective,Randomized Controlled Study

The objective of the present study was to evaluate the clinical, radiological, and functional outcomes of a subscapularis transthoracic surgical approach and a posterolateral surgical approach with debridement, bone graft fusion, and internal fixation for the treatment of upper thoracic tuberculosis.There is currently debate over the best surgical approach for the treatment of upper thoracic tuberculosis. Traditionally, the subscapularis transthoracic approach has been preferred; however, the posterolateral approach has gained popularity in the past few years.A prospective, consecutive cohort of 43 upper thoracic tuberculosis patients with a mean age of 39 years (range: 20–52 years) was followed up for a minimum of 12 months (range: 12–60 months). Patients were randomly divided into 2 groups. Group A (n = 21) was treated by the subscapularis transthoracic approach and group B (n = 22) was treated by the posterolateral approach. All cases were evaluated for clinical, radiological, and functional outcomes. Intraoperative blood loss, operative duration, intraoperative and postoperative complications, hospital stay, the cure rate, fusion time, and the Frankel scale were used for clinical and functional evaluation, whereas the kyphosis angle was used for radiological evaluation.Grafted bones were fused by 10 months in all cases. There was no statistically significant difference between groups before surgery in terms of gender, age, segmental tuberculosis, erythrocyte sedimentation rate (ESR), Frankel scale, or Cobb''s angle (P > 0.05). The average operative duration for Group B was lower than that of Group A. There were no significant differences in intraoperative blood loss, intraoperative and postoperative complications, hospital stay, grafted bone fusion time, or cure rate between groups (P > 0.05). The Cobb''s angle correction rate for group B (68.5%) was significantly better than that of group A (30.9%). The neurological score showed significant postoperative improvement in both groups, with no significant difference between the groups.The subscapularis transthoracic approach and the posterolateral approach with debridement, bone graft fusion, and internal fixation are both sufficient and satisfactory for the surgical treatment of upper thoracic tuberculosis. However, the posterolateral approach is superior to the subscapularis transthoracic approach in terms of surgical trauma, operative time, and kyphosis correction.

营养风险与腹膜后肿瘤患者住院时间的相关性研究

目的 探讨营养风险与腹膜后肿瘤患者住院时间的相关性。方法 采用回顾性研究，选取2012年1月至2018年12月四川大学华西医院血管外科新入院腹膜后肿瘤患者60例，采用营养风险筛查表评估患者营养风险，收集患者体质指数、围术期血红蛋白和白蛋白水平、住院天数、术后恶心呕吐发生情况、术后排气、排便时间和首次进食时间。采用单因素分析比较不同患者住院时间，采用多重线性逐步回归分析患者住院时间的影响因素。结果 纳入的60例腹膜后肿瘤患者中，40例患者（66.7%）术前存在营养风险，52例患者（86.7%）术后存在营养风险；单因素分析显示，患者术前、术后营养风险 （术前P<0.001，术后P=0.043）、术前白蛋白 （P=0.019）、术后血红蛋白 （P=0.019）、术后白蛋白（P=0.025） 水平以及术后恶心呕吐 （P=0.001） 均会影响患者的住院时间；患者住院时间与围术期营养风险筛查工具评分、术后首次进食时间、术后排气时间和排便时间具有相关性，且相关性强（r=0.759~0.770； P<0.01）；多因素分析显示术前营养风险是腹膜后肿瘤患者住院时间的重要预测因素（β=0.399）。结论 术前营养风险是腹膜后肿瘤患者住院时间的预测因子。     

The influence of processed total non-forward and non-motile sperm count on the outcome of artificial insemination with the husband’s semen

BackgroundArtificial insemination with the husband’s semen (AIH) is an economical and noninvasive method of infertility treatment. However, AIH’s pregnancy rate is much lower than in vitro fertilization (IVF) as its multiple and complex uncertainty factors. Semen quality has been one of the main factors which affect the pregnancy outcome of AIH.MethodsThe relevant parameters of 1,142 AIH cycles were retrospectively studied, including the general parameters and the semen quality parameters among clinical pregnancy, biochemical pregnancy, non-pregnancy group, age, infertility duration, infertility type, body mass index (BMI), cycle count, morphology in previously semen examination, and semen quality parameters on the day of AIH.ResultsThe statistically significant difference was only found on processed total non-forward and non-motile sperm count (N-TFMSC). The mean processed N-TFMSC in the biochemical pregnancy group was 6.37±4.27 million, significantly higher than the other two groups (vs. 4.40±3.15 million or vs. 4.48±3.60 million, P<0.05). The study was then divided into two groups according to processed N-TFMSC, Group 1 ≤5.0 million, and Group 2 >5.0 million. A statistical increase in biochemical pregnancy rate was observed when the processed N-TFMSC was >5.0 million (2.72% vs. 0.90%).ConclusionsProcessed N-TFMSC may be one of the independent factors on AIH’s outcome; it should be given equal attention the same as processed total forward motile sperm count (TFMSC).     

骨折早期调节RANKL表达对骨折愈合影响的实验研究

目的通过对大鼠股骨骨折早期局部应用重组人骨保护素Fc融合蛋白(OPG-Fc),研究调节骨保护素(OPG)和核因子-κB受体活化因子配体(RANKL)的表达变化对骨折早期的影响,探讨其表达调节方式及作用机制。方法 48只雌性SD大鼠随机分成实验组和对照组,每组24只。建立大鼠股骨骨折模型,于术后第7天、第14天、第21天、第28天4个时间节段分批处死模型,标本切片后通过HE染色观察骨折愈合情况,免疫组织化学染色研究破骨细胞数量变化。结果 HE染色示单纯骨折组呈典型骨折愈合过程,而骨折局部注射OPG组骨痂形成及改造提前,骨折愈合加速。免疫组织化学染色显示在第7天、第14天、第21天、第28天各个时间节段单纯骨折组破骨细胞计数值均高于骨折应用OPG组,差异有统计学意义(P0.05)。结论骨折早期调节RANKL表达,当RANKL/OPG比值减小时,骨折局部破骨细胞减少,骨痂形成增多,骨折愈合加速。
