白术茯苓汤及其配伍对脾虚大鼠胃肠激素的影响

目的：探讨益气健脾方剂治疗脾虚证的配伍规律。方法：采用苦寒泻下法复制大鼠脾虚模型，运用放射免疫分析法（RIA）检测白术茯苓汤及其与补气药。行气药及除湿药的不同配伍对脾虚大鼠胃泌素（GAS）、胃动素（MTL）及血管活性肠肽（VIP）的含量影响。结果：与正常对照组比较，脾虚模型大鼠GAS、MTL降低（P＜0．01），VIP升高（P＜0．01）；与自然恢复组比较，各治疗组以上部分或全部指标均有不同程度的改善，其中，以综合配伍组改善作用最优。结论：白术茯苓汤的脾虚大鼠胃肠激素的紊乱的某些指标，有一定的改善作用，综合配合组以上指标的改善，优于白术茯苓汤组及其余各配伍组，说明中医关于复方配伍的理论与实践，有其科学价值。     

The difficult primary hip

Hip arthroplasty is a common orthopaedic procedure with proven long-term success and reliable results. A wide range of associated conditions may affect the outcome of the arthroplasty and the surgeon has to keep these in mind when planning the surgery. In this article, such situations are discussed and recommendations are drawn from the evidence available in literature.     

六味地黄冲剂对肾阴虚病人血浆中锌铜含量的影响

肾阴虚病人血浆中锌、铜含量均较正常人血浆中锌,铜含量明显增高(P<0.01)。男女性别间本组未见差异。服用治疗肾阴虚药物六味地黄3种剂型后均使锌,铜含量明显降低(P<0.01),六味地黄冲剂与汤剂效果一致。     

Hereditary plasma thromboplastin antecedent (PTA,FXI)

A rare case of factor XI (PTA) deficiency was discovered in a Saudi family in the Riyadh area. Nine members of the family were studied. Two were found to have a severe PTA deficiency’ levels of factor XI clotting activity were 0.01 i.u./ml and 0.02 i.u./ml respectively. Both plasmas were markedly deficient in factor XI antigen and appeared to be negative for cross-reactive material (CRM-). The parents were first cousins and both were found to have a minor PTA deficiency. Factor XI levels were: mother 0.048 i.u./ml and father 0.33 i.u./ml. Another sibling was found to have a FXI level of 0.47 i.u./ml. Menorrhagia and bleeding for 1 day after tooth extraction were the main bleeding manifestations found in one member with severe PTA deficiency. Clinically this member presented with iron deficiency anaemia. Other family members had no significant history of bleeding tendency. This is the first report of a Saudi Arabian family with PTA deficiency.     

Tension-free vaginal tape for the treatment of urodynamic stress incontinence with intrinsic sphincteric deficiency

The purpose of this study was to evaluate the outcome of tension-free vaginal tape (TVT) procedure in women with urodynamic stress incontinence diagnosed as having intrinsic sphincteric deficiency (ISD). The combination of a maximal urethral closure pressure <20 cm H₂O and a Valsalva leak point pressure <60 cm H₂O was considered as diagnostic of ISD. Subjects with detrusor overactivity on preoperative urodynamics were excluded. A total of 35 patients with both low closure pressure and leak point pressure were enrolled. Bladder perforation occurred in three (8.6%) cases. Postoperative urinary voiding difficulties occurred in nine (25.7%) women. Two patients underwent surgical detension of the tape, with complete resolution of urinary retention and no relapse of incontinence. Women with postoperative voiding dysfunction had a significantly lower detrusorial pressure at the peak flow on preoperative urodynamics compared to those who voided efficiently after TVT. The mean (range) follow-up time was 12.5 months (3–36). The objective cure rate for stress incontinence was 91.4%. Two of the three (66%) patients in whom the TVT procedure failed had a fixed urethra. De novo urge incontinence was found in five (14.3%) patients.     

Bone disorders following total gastrectomy

Bone disorders following gastrectomy were studied by measuring absolute and relative bone mineral density of the Wards triangle, serum 1,25-(OH)₂-D, alkaline phosphatase, and total serum calcium. The subjects were 20 males who had undergone total gastrectomy not more than three months previously (group A₁). Seventeen of these patients were reviewed three years later (group A₂). Absolute and relative bone density were significantly lower in group A₂ than in A₁ (0.52 ± 0.011 g/cm² versus 0.6 ± 0.014 g/cm²,P<0.01 and 85.5 ± 1.4% age-matched control versus 95 ± 1.3%,P<0.01). 1,25-(OH)₂-D was significantly lower in group A₂ than in group A₁ (14.3 ± 0.97 pg/ml versus 20.6 ± 1.02 pg/ml,P<0.01). There was no difference in alkaline phosphatase and calcium serum concentration. The mean weight loss was 6.26 ± 0.57% over the follow-up period, and weight loss correlated with absolute and relative bone density (r=–0.74,P<0.01). There was a positive correlation between 1,25-(OH)₂-D and absolute or relative bone density (r=0.67,r=0.62 andP<0.01). These data suggest that bone density decrease has already occurred three years after total gastrectomy and is positively correlated to 1,25-(OH)₂-D deficiency. As no differences in serum alkaline phosphatase and serum calcium concentration were found, these factors are of little value for the early detection of postgastrectomy bone disorders, whereas weight loss is a valuable screening parameter.     

广西毛南族农村妇女铁营养状况调查

对450名广西环江县毛南族农村育龄妇女进行血清铁蛋白(SF)、红细胞游离原卟啉(FEP)及血红蛋白(Hb)3项铁指标测定.结果发现:铁缺乏症患病率为27.8%(其中ID4.2%,IDE 7.8%,IDA 15.8%).随着孕次或产次的增加,血红蛋白水平逐渐下降,铁缺乏症患病率逐渐增高.有妊娠或分娩史的妇女与未孕或未生育的妇女血红蛋白水平与铁缺乏症患病率比较均有显著性差异(P<0.05).     

Is there a ‘Basque’ profile regarding autosomal recessive deficiencies of coagulation factors?*

When excluding haemophilia and von Willebrand disease, coagulation factors deficiencies constitute rare autosomal recessive disorders (<1 in 500,000) of less precisely defined epidemiology. We have reported herein the distribution of these entities in the French Basque Country, a genetic isolate of very old individualization with peculiar biological specificities. The prevalence of these disorders was markedly high, especially, as already shown, factor XI deficiency. This unusual profile needs to be discussed in the view of population genetics.
