       目的   对比分析双极半髋关节置换术(BHA)与全髋关节置换术(THR)治疗股骨颈骨折(FNF)的效果。方法   回顾性收集北京中医药大学东直门医院洛阳医院2019年6月—2023年4月90例FNF患者临床资料,依照手术治疗方案差异分为两组,BHA组(45例)行BHA治疗,THR组(45例)行THR治疗,比较两组围术期指标、术前及术后3 d炎症因子水平、术后6个月髋关节活动度、术前及术后6个月生活质量[欧洲生活质量评分(EQ-5D评分)]。  THR组手术时间(108.76±15.33)min、下床活动时间(40.37±10.24)h、住院时间(19.02±5.11)d均较BHA组[(53.49±10.12)min、(25.92±7.15)h、(15.16±4.87)d]长(t分别为20.184、7.761、3.668,均P<0.05),术中失血量(318.69±35.14)mL、术后引流量(129.74±21.03)mL均较BHA组[(224.07±29.35)mL、(90.35±17.48)mL]多(t分别为13.863、9.663,均P<0.001);组间并发症发生率比较差异无统计学意义(P>0.05);术后3 d,BHA组血清白细胞介素-1为(17.35±3.06)pg/L、白细胞介素-6为(24.82±4.31)pg/L、C-反应蛋白为(26.17±4.59)pg/L,低于THR组的(20.16±3.48)pg/L、(27.04±5.06)pg/L、(28.90±5.12)pg/L(t分别为4.068、2.241、2.663,均P<0.05);两组术后6个月髋关节内旋、屈曲、外旋、外展、内收活动度及EQ-5D评分对比差异均无统计学意义(均P>0.05)。结论  THR相比,BHA能减少FNF患者围术期失血量,降低术后炎症因子表达水平,缩短手术及下床活动时间,促进恢复。
      Objective  To compare and analyze the effects of bipolar hemihip replacement(BHA)and total  hip replacement(THR)in the treatment of femoral neck fracture(FNF).Methods  The clinical data of 90 patients with FNF in the Luoyang Hospital,Dongzhimen Hospital,Beijing University of Chinese Medicine,from June 2019 to April 2023 were retrospectively collected.The patients were divided into two groups according to the difference in surgical treatment plan.The BHA group(45 cases)received BHA treatment,and the THR group(45 cases)received THR treatment.The perioperative indicators,preoperative and postoperative inflammatory factor levels,postoperative hip joint mobility at six months,preoperative and postoperative quality of life [European Quality of Life Scale(EQ-5D score)]were compared between the two groups.Results  The operation time(108.76±15.33)min,ambulation time(40.37±10.24)h,and hospitalization time(19.02±5.11)d in the  THR  group were longer than those in the BHA group [(53.49±10.12)min,(25.92±7.15)h,(15.16±4.87)d](t=20.184,8.630,3.668,respectively,all P<0.05).The intraoperative blood loss(318.69±35.14)mL and  postoperative  drainage volume(129.74±21.03)mL were both higher than those in the BHA group [(224.07±29.35)mL,(90.35±17.48)mL]t=13.863,9.663,respectively,all P<0.001).There was no significant difference in the incidence of complications between the groups(P>0.05).Three days after surgery,the serum levels of interleukin-1,interleukin-6,and C-reactive protein in the BHA group were(17.35±3.06)pg/L,(24.82±4.31)pg/L,and(26.17±4.59)pg/L,respectively,which were lower than those in the THR group(20.16±3.48)pg/L,(27.04±5.06)pg/L,and(28.90±5.12)pg/L(t=4.068,2.241,2.663,respectively,all P<0.05).There was no significant difference in the range of motion of internal rotation,flexion,external rotation,abduction,and adduction of the hip joint and EQ-5D scores between the two groups at six months after surgery(all P>0.05).Conclusions  Compared with THR,BHA can reduce perioperative blood loss in FNF patients,reduce postoperative inflammatory factor expression level,shorten operation and ambulation time,and promote recovery.

Comparison of the clinical effects of NIPPV and NCPAP as a noninvasive respiratory support for preterm infants after extubation

:516-522
 
       目的    探究经鼻间歇正压通气(NIPPV)和经鼻持续正压通气(NCPAP)作为早产儿呼吸窘迫综合征气管插管机械通气拔管后无创呼吸支持过渡的临床效果的差异。方法   纳入2021年1月—2023年6月在广东省吴川市妇幼保健计划生育服务中心治疗的新生儿呼吸窘迫综合征早产儿66例,用随机数字表法将患儿分为NIPPV组(33例)和NCPAP组(33例)。NIPPV组患儿予经鼻间歇正压通气作为过渡期无创呼吸支持,NCPAP组患儿则予以经鼻持续正压通气作为过渡期无创呼吸支持。对比两组患儿治疗前后血气分析结果、脱机失败率、无创呼吸支持时间、无创后吸氧时间、总给氧时间等指标。结果  接受无创呼吸支持12 h后,NIPPV组患儿的PaO2升至(76.46±1.10)mmHg,高于NCPAP组患儿的(75.51±2.15)mmHg(t=2.249,P=0.028)。此外,NIPPV组患儿的SaO2升至(96.36±0.52)%,也高于NCPAP组患儿的(96.07±0.59)%(t=2.138,P=0.034)。而NIPPV组患儿的PaCO2则降至(41.39±0.74)mmHg,较NCPAP组患儿的(41.87±0.95 )mmHg低(t=-2.230,P=0.025)。NIPPV组无创呼吸支持时间为(3.09±0.52)d,短于NCPAP组的(3.45±0.62)d,且该差异有统计学意义(t=2.584,P=0.012)。同样的,NIPPV组总给氧时间(9.52±0.76)天较NCPAP组的(10.00±0.79)天短,且该差异有统计学意义(t=-2.548,P=0.013)。而两组在脱机失败率、无创呼吸支持后吸氧时间、不良反应发生率等方面比较差异无统计学意义(均P>0.05)。结论   与NCPAP模式相比,早产儿拔管后应用NIPPV模式进行无创呼吸支持取得的临床效果更优。

Study on the anti-fatigue effect of compound Huangqi granules on mice and its mechanism

:509-515
 
       目的   探讨复方黄芪颗粒(CHG)的抗疲劳作用及其机制。方法  48只雄性BALB/C小鼠随机分为空白对照组、低剂量(9.1 g/kg)、中剂量(18.2 g/kg)、高剂量(27.3 g/kg)CHG 3个试验组,每组12只。试验组给予不同剂量的复方黄芪颗粒溶液灌胃,空白对照组小鼠给予等体积生理盐水。给药30 d后,检测小鼠体内相关指标变化,观察其抗疲劳作用并分析相关机制。结果   与空白对照组相比,试验组小鼠体质量差异无统计学意义(P>0.05),小鼠力竭游泳时间及转棒耐力时间均明显延长(P<0.01),血尿素氮(BUN)、乳酸脱氢酶(LDH)、丙二醛(MDA)水平明显降低P<0.01),肝糖原和肌糖原水平升高(P<0.05),超氧化物歧化酶(SOD)活性升高(P<0.01)。体外抗氧化试验表明CHG以剂量依赖性方式清除2,2-联氮-二(3-乙基-苯并噻唑-6-磺酸)二铵盐(ABTS)和1,1-二苯基-2-三硝基苯肼(DPPH)自由基。当CHG质量浓度为100.000 0 mg/mL时,CHG对DPPH自由基清除能力可达85.030 3%。当CHG质量浓度为25.000 0 mg/mL时,CHG对ABTS自由基清除能力可达96.357 2%。结论  CHG具有抗疲劳的作用,其作用机制可能与抗氧化作用相关。

宫腔镜病灶切除术与超声监测下吸宫术治疗剖宫产瘢痕部位妊娠的有效性比较

Comparison of effectiveness between hysteroscopic resection surgery and ultrasound-guided uterine aspiration in the treatment of cesarean scar pregnancy

:500-504
 
       目的   比较宫腔镜病灶切除术与超声监测下吸宫术治疗剖宫产瘢痕部位妊娠(CSP)的有效性。   回顾性分析2021年7月—2023年10月在南宁市妇幼保健院确诊为I、Ⅱ型CSP并接受治疗的129例患者,停经时间在38~83 d,中位停经时间48 d。其中42例患者接受了宫腔镜病灶切除术治疗(A组),87例患者接受超声监测下吸宫术治疗(B组),比较两组患者术后1、3、7、14 d的人绒毛膜促性腺激素水平以及手术出血量、手术时间、住院时间、住院花费。结果   两组患者在术后1 d,血清HCG水平下降,下降幅度均超过50%,且A组患者术后1 d血清HCG的下降幅度及下降速率大于B组患者(P<0.05);术后3、7、14 d,两组血清HCG水平仍持续下降。另外,A组患者手术出血量、手术时间、住院时间、住院花费分别为(15.35±14.53)mL、(60.73±53.05)min、(4.33±1.90)d、(6 689.23±2 216.19)元;B组患者手术出血量、手术时间、住院时间、住院费用分别为(26.09±29.24)mL、(51.59±54.46)min、(4.82±1.83)d、(6 270.34±2 547.85)元。A组患者术中出血量低于B组、住院时间短于B组(P<0.05),手术时间及住院费用与B组比较差异无统计学意义(P均>0.05)。结论   宫腔镜病灶切除术与超声监测下吸宫术均能有效治疗CSP,但宫腔镜病灶切除术在术后血清HCG的下降幅度及下降速率、术中出血量、住院时间等方面优于超声监测下吸宫术,而且手术时间和住院费用并没有显著增加。
       Objective  To compare the efficacy between hysteroscopic  resection surgery and ultrasound-guided uterine aspiration in the treatment of cesarean scar pregnancy(CSP).Methods  A  retrospective analysis was performed in 129 patients diagnosed with CSP(type I or Ⅱ)and treated in Nanning Maternal and Child Health Hospital from July 2021 to October 2023.Their duration of amenorrhea was between 38~83 d,with a median of 48 days.Among them,42  patients were treated with hysteroscopic resection surgery therapy(group A),87 patients were treated with ultrasound-guided uterine aspiration therapy and(group B).Then,the levels of human chorionic gonadotropin(HCG),the amount of the intraoperative bleeding volume,surgical time,hospitalization time,and hospitalization expenses were compared between the two groups at one,three,seven and 14 days postoperativey.Results  After one day of surgery,the serum HCG levels of two groups significantly decreased,with a decrease of more than 50%,and the magnitude and  rate of  decrease in  serum HCG levels of group A were  significantly larger than those of group B(P<0.05);After three,seven,and 14 day of surgery,serum HCG levels continued to decrease.Furthermore,the intraoperative bleeding volume,surgical time,hospitalization time,hospitalization expenses in group A were(15.35±14.53)mL,(60.73±53.05)min,(4.33±1.90)d,(6 689.23±2 216.19)yuan,respectively.That in group B were(26.09±29.24)mL,(51.59±54.46)min,(4.82±1.83)d,(6 270.34±2 547.85)yuan,respectively.Compared to group B,the intraoperative bleeding volume of group A was significantly lower(P<0.05),and the hospitalization time is shorter,while there was no significant difference in surgical time and hospitalization expenses.Conclusions  Both of hysteroscopic resection surgery and ultrasound-guided uterine aspiration can treat cesarean scar pregnancy effectively,but the former is superior to the latter in terms of the magnitude and rate of decrease in serum HCG levels after surgery,intraoperative bleeding volume,and hospitalization time,with no significant increase in surgical time and hospitalization expenses.
