目的评价综合治疗对难治性便秘的疗效及影响因素。方法将84例难治性便秘分为非重叠组和重叠组。应用个体化综合治疗4周,观察便秘症状评分变化及总有效率,分析IC患者的重叠症状和心理障碍状态对疗效的影响。结果(1)84例便秘患者中,重叠组和非重叠组分别占40.5%和59.5%。(2)重叠组和非重叠组的总有效率分别为50.0%和78.0%(P<0.05)。(3)对37例IC患者的心理测试调查显示,59.4%(22/37)有心理障碍状态,重叠组和非重叠组伴有心理障碍状态对治疗的总有效率分别为4.8%和31.5%(P<0.05)。结论适合个体化的综合治疗使多数难治性便秘缓解症状,但伴有重叠症状,尤其心理障碍状态则影响疗效。     

Transitions to parenthood: his,hers, and theirs

This study explores marital processes that may underlie the apparent decline in satisfaction with marriage in partners becoming parents for the 1st time. The study assessed 47 couples expecting a 1st child and 15 couples not yet decided about having a child at pretest, post 1 (6 months post partum of 9 months after pretest) and post 2 (18 months postpartum or 21 months after pretest). Questionnaires examined: 1) psychological sense of self; 2) partners' role arrangements and communication; 3) parenting ideology; 4) perceptions of the family of origin; and 5) social support and life stress, including parents' work patterns. Parenthood seems to bring more change, and more negative change, in each of the 5 domains of family life that were investigated for comparable couples not having a 1st child experience over a similar period of time. Quantitative data support this conclusion in 4 of the 5 domains (individuals sense of self, marital, parent-child, and outside the family). Interview data suggest that new parents' relationships with their families of origin also undergo change at this time. Although shifts within domains often showed patterns similar to change in overall satisfaction with the marriage, the connection between the 2 was not linear and direct, especially for women. Men and women in transition to parenthood become increasingly different from one another; the results suggest that increased gender differentiation accompanying the transition to parenthood is a factor in accounting for marital satisfaction decline.     

Global versus local processing: Is there a hemispheric dichotomy?

A major dichotomy proposed for lateralized information processing is that the right and left cerebral hemispheres are "global" and "analytic" processors respectively. Here three experiments employed a tachistoscopic recognition paradigm with letter patterns varying in size and composition. No visual field asymmetries in RT were found in the first two experiments, although statistical power was high and a Stroop-like effect ("global precedence") was supported. Experiment 3 resulted in a right field advantage for vocal naming responses yet no asymmetry for manual responses, suggesting that both hemispheres can recognize global and local patterns, but that introduction of a laterally controlled response independently determines asymmetry.

脑卒中肺部感染危险因素及血清免疫炎性因子的预测价值

目的基于主成分分析(PCA)-决策树模型分析脑卒中肺部感染的危险因素及血清免疫炎性因子的预测价值。方法回顾性分析2014年12月-2019年12月江西省上饶市人民医院确诊的176例脑卒中患者,根据是否发生肺部感染,分为感染组40例和未感染组136例。记录患者临床特征,检测血白细胞(WBC)计数、血清C-反应蛋白(CRP)、降钙素原(PCT)和可溶性白细胞介素-2受体(SIL-2R)水平。采用Logistic回归和卡方自动交叉检验(CHAID)模型分析影响脑卒中后肺部感染的危险因素;受试者工作特征曲线(ROC)分析血WBC、CRP、PCT、SIL-2R预测肺部感染的价值。结果脑卒中肺部感染与患者年龄、卒中类型、是否合并糖尿病、吸烟史、吞咽困难、意识障碍、侵入性操作有关(P<0.05);感染组患者血WBC、CRP、PCT和SIL-2R水平高于未感染组(P<0.05);糖尿病、侵入性操作、CRP和PCT均为影响脑卒中患者肺部感染的独立危险因素(P<0.05);PCA-ROC分析显示,血WBC、CRP、PCT、SIL-2R和联合预测主成分1(PC1)的曲线下面积(AUC)分别为0.670、0.816、0.854、0.686、0.918;PCA-卡方自动交互检测(CHAID)模型分析显示,WBC、CRP、PCT、SIL-2R和PC1预测肺部感染的准确率为77.33%、84.72%、86.90%、79.02%和89.24%。结论血清PCT水平可用于预测脑卒中患者肺部感染的发生,临床可重点关注合并糖尿病、意识障碍和侵入性操作的患者。

目的 探讨血清CA125和唾液酸（SA）对卵巢子宫内膜异位症及卵巢良性肿瘤的诊断价值。方法 对30例卵巢巧克力囊肿、30例卵巢良性肿瘤和15例正常妇女采用放免法测定血清CA125值,比色法测定血清SA值。结果 卵巢巧克力囊肿组血清CA125均值明显高于良性肿瘤组及正常对照组（P＜0．01）,而血清SA增值三组间无显著性差异（P＞0．05）。结论 血清CA125测定对巧克力囊肿有辅助诊断价值,且有助于与卵巢良性肿瘤的鉴别。     

The changing face of reoperative parathyroidectomy: a single-centre comparison of 147 parathyroid reoperations

IntroductionReoperative parathyroidectomy for persistent and recurrent primary hyperparathyroidism is dependent on radiology. This study aimed to compare outcomes in reoperative parathyroidectomy at a single centre using a combination of traditional and newer imaging studies.Materials and methodsRetrospective case note review of all reoperative parathyroidectomies for persistent and recurrent primary hyperparathyroidism over five years (June 2014 to June 2019; group A). Imaging modalities used and their positive predictive value, complications and cure rates were compared with a published dataset spanning the preceding nine years (group B).ResultsFrom over 2000 parathyroidectomies, 147 were reoperations (101 in group A and 46 in group B). Age and sex ratios were similar (56 vs 62 years; 77% vs 72% female). Ultrasound use remains high and shows better positive predictive value (76% vs 57 %). 99mTc-sestamibi use has declined (79% vs 91%) but the positive predictive value has improved (74% vs 53%). 4DCT use has almost doubled (61% vs 37%) with better positive predictive value (88% vs 75%). 18F-fluorocholine positron emission tomography-computed tomography and ultrasound-guided fine-needle aspiration for parathyroid hormone are novel modalities only available for group A. Both carried a positive predictive value of 100%. Venous sampling with or without angiography use has decreased (35% vs 39%) but maintains a high positive predictive value (86% vs 91%). Cure rates were similar (96% vs 100%). Group A had 5% permanent hypoparathyroidism, 1% permanent vocal cord palsy and 1% haematoma requiring reoperation. No complications for group B.ConclusionOptimal imaging is key to good cure rates in reoperative parathyroidectomy. High-quality, non-interventional imaging techniques have produced a shift in the preoperative algorithm without compromising outcomes.     

Autologous peripheral blood stem cell transplantation in the patients with hematologic malignancies and solid tumors

Objective To evaluate the long-term therapeutic effects of autologous peripheral blood st em cell transplantation (auto-PBSCT) on the treatment of hematological and soli d tumors. Methods Fifty-one patients were recruited in this auto-PBSCT study, in which several p otentially important parameters were studied including the optimal time for stem cell co llection, the dose of stem cell reinfusion, the time of hematopoietic reconsti tution, the disease free survival (DFS) and overall survival (OS), complication s related to transplantation, and maintenance chemotherapy after auto-PBSCT. Results After APBSCT, 3-year and 5-year survival rates of NHL were 83.3%; those of AM L were 74.7%; those of MM were 37.9% and 19%; those of ALL were 40% and 0% res pectively. Hematopoietic reconstitution was greatly promoted by granulocyte col ony stimulating factor (G-CSF). The mean time for patients’ neutrophil to reco ver up to &gt;0.5×10(9) /L after APBSCT was 11.14 days in the group of the patien ts receiving G-CSF in contrast to 17.6 days in the group receiving no G-CSF. The most common complications of transplantation were fever, liver dysfunction and hypokalaemia, which were curable. No death was due to transplantation related complications.Conclusion Comparing with conventional chemotherapy, our study suggests that auto-PBSCT i s a very important therapeutic option that can significantly improve the prognos is in the patients with hematological and solid tumors, especially in the patien ts with AML and NHL.
