[Objective]To summarize the experiences of total hip replacement with cementless joint components in the treatment of osteoarthritis secondary to acetabular dysplasia in adults and to evaluate its early effect. [Method]From March 2000 to March 2007, thirty hips in 25 adult patients with osteoarthritis secondary to acetabular dysplasia undergoing total hip replacement with cementless joint components were included in this study. Of the patients, 5 were male and 20 were female.Their ages ranged from 35 to 55 years with an average age of 55 years. The patients mainly complained of pain and claudication. According to the Hartofilakidis classification , Semi-dislocation occurred in 21 hips and high-dislocation in 9 hips.Five patients underwent bilateral total hip replacements and twenty patients had unilateral total hip replacement.[Result]The duration of follow-up ranged from 8 months to 7 years ( average 3 years and 9 months ) . The average Harris score was increased from 36.09 to 88.21 points, They could take care of themselves and returned to their previous job. All the patients were pain-free and there was no sign of aseptic looseing or subsidence.[Conclusion]Total hip replacement with cementless joint components is an effective method for the treatment of osteoarthritis secondray to acetabular dysplasia in adults.The key point to the success for operation are appropriate cementless joint components, deepened medial wall of the acetabulum and improved the techniques of bone graft in the true acetabulum.

Objective To assess the prevalence of Personality Diagnostic Questionnaire (PDQ)personality deviations in patients referred for functional dyspepsia (FD) with reliable and universal psychological measures, and to explore the relationship between co-occurring PDQ-personality deviations and functional dyspepsia. Methods The sample comprised 246 patients referred for functional dyspepsia. Four groups were divided according to their patterns of gastrointestinal symptoms: the FD group, FD with refluxlike symptom group(FD + RS group), FD with irritable bowel syndrome group( FD + IBS group), and FD with reflux-like symptom and irritable bowel syndrome group ( FD + RS + IBS group). Participants were assessed with the Personality Diagnostic Questionnaire for DSM-Ⅳ ( PDQ-4 ) to evaluate the presence of personality deviations. Results Overall 65% patients scored positive for any personality deviation, male and female alike. Cluster C (anxious/fearful) personality was most commonly found in FD patients (142 patients, 57.7% ). The FD + IBS group and the FD + RS +IBS group had significantly higher total PDQ scores than the FD group (23.39 ± 8. 77 and 24. 22 ± 10. 97 vs 18.98 ± 11.88, P ＜ 0. 05, respectively),indicating that FD patients with greater level of personality deviations tend to report other symptoms involving the esophagus and lower gastrointestinal tract. Reflux-like symptom without actual pathological acid regurgitation indicated cluster A (odd/eccentric) personality deviations. Conclusions The current study shows personality deviations are common in patients referred for functional dyspepsia. Negative emotions,maladaptive coping, and lack of social support, may strongly influence their healthcare-seeking behavior.There is no single personality type specific for some kind of gastrointestinal symptom. But FD patients with personality deviations tend to report other symptoms involving the esophagus and lower gastrointestinal tract.

Objective:To explore the value of serum procalcitonin (PCT) and acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score on predicting prognosis of elderly patients with sepsis.Methods:A retrospective cohort study, patients with sepsis who admitted to the department of emergency and the department of geriatric medicine of Peking University Third Hospital from March 2020 to June 2021 were enrolled. Patients' demographics, routine laboratory examinations, APACHE Ⅱ score that within 24 hours of admission were obtained from their electronic medical records. The prognosis during the hospitalization and one year after discharge were collected, retrospectively. Univariate and multivariate analysis of prognostic factors were performed. And Kaplan-Meier survival curves were used to examine overall survival.Results:A total of 116 elderly patients met inclusion criteria, 55 were alive and 61 were died. On univariate analysis, clinical variables such as lactic acid [Lac, hazard ratio ( HR) = 1.16, 95% confidence interval (95% CI) was 1.07-1.26, P < 0.001], PCT ( HR = 1.02, 95% CI was 1.01-1.04, P < 0.001), alanine aminotransferase (ALT, HR = 1.00, 95% CI was 1.00-1.00, P = 0.143), aspartate aminotransferase (AST, HR = 1.00, 95% CI was 1.00-1.01, P = 0.014), lactate dehydrogenase (LDH, HR = 1.00, 95% CI was 1.00-1.00, P < 0.001), hydroxybutyrate dehydrogenase (HBDH, HR = 1.00, 95% CI was 1.00-1.00, P = 0.001), creatine kinase (CK, HR = 1.00, 95% CI was 1.00-1.00, P = 0.002), MB isoenzyme of creatine kinase (CK-MB, HR = 1.01, 95% CI was 1.01-1.02, P < 0.001), Na ( HR = 1.02, 95% CI was 0.99-1.05, P = 0.183), blood urea nitrogen (BUN, HR = 1.02, 95% CI was 0.99-1.05, P = 0.139), fibrinogen (FIB, HR = 0.85, 95% CI was 0.71-1.02, P = 0.078), neutrophil ratio (NEU%, HR = 0.99, 95% CI was 0.97-1.00, P = 0.114), platelet count (PLT, HR = 1.00, 95% CI was 0.99-1.00, P = 0.108) and total bile acid (TBA, HR = 1.01, 95% CI was 1.00-1.02, P = 0.096) shown to be associated with poor prognosis. On multivariable analysis, level of PCT was an important factor influencing the outcome of sepsis ( HR = 1.03, 95% CI was 1.01-1.05, P = 0.002). Kaplan-Meier survival curve showed that there was no significant difference with respect to the overall survival between the two groups, with patients of PCT ≤ 0.25 μg/L and PCT > 0.25 μg/L ( P = 0.220). It also showed that the overall survival rate in patients with high APACHE Ⅱ score (> 27 points) was significantly lower than that in patients with low APACHE Ⅱ score (≤ 27 points, P = 0.015). Conclusion:Serum PCT level is valuable prognostic factors of elderly patients with sepsis, and higher APACHE Ⅱ score (> 27 points) indicates a poor prognosis.

Objective:To investigate the risk factors for nonunion after surgery for femoral shaft fractures in order to reduce them.Methods:The clinical data were retrospectively analyzed of the 804 patients with femoral shaft fracture who had been treated from January 2014 to December 2020 at Department of Orthopaedics, Xijing Hospital. There were 575 males and 229 females, aged from 18 to 96 years (average, 43.7 years). The patients were divided into 2 groups according to whether nonunion had occurred after surgery: a nonunion group of 112 cases and a fracture healing group of 692 cases. The preoperative general data, such as age, gender and fracture type, as well as intraoperative and postoperative data, such as operation time, internal fixation method, reduction method and internal fixation failure, were compared between the 2 groups. Items with P<0.05 were included in the multivariate logistic regression analysis to identify the risk factors for nonunion. Results:There were statistically significant differences between the nonunion group and the fracture healing group in smoking history, drinking history, injury mechanism, injury type, multiple injuries, fracture AO classification, fixation method, internal fixation failure, postoperative infection and use of non-steroid anti-inflammtory drugs ( P<0.05). Multivariate logistic regression analysis showed that smoking ( OR=3.261, 95% CI: 2.072 to 5.133, P<0.001), high energy injury ( OR=2.010, 95% CI: 1.085 to 3.722, P=0.026), multiple injuries ( OR=3.354, 95% CI: 1.985 to 5.669, P<0.001), AO type 32-C fracture (type 32-C fracture used as a reference, P=0.034), internal fixation failure ( OR=3.517, 95% CI: 1.806 to 6.849, P<0.001), external stent fixation (external stent fixation used as a reference, P=0.009) were the risk factors for nonunion after femoral shaft fractures. Conclusions:After surgery for patients with femoral shaft fracture, special attention should be paid to those with a smoking habit, high-energy injury, multiple injuries, AO type 32-C fracture, external stent fixation or a failed internal fixation, because they are high-risk groups prone to postoperative nonunion.

Objective To observe neuropsychological development status in children after surgical treatment of congenital heart diseases(CHDs)and analyze the risk factors. Methods 89 children who received outpatient review in Fuwai Hospital from September 2015 to March 2016 after surgical treatment of CHDs were recruited in this study and 90 normal children were recruited as the control group. The children with CHDs were divided into simple CHDs group(RACHS- 1 score≤2)and com-plex CHDs group(RACHS- 1 score≥3)according to RACHS- 1 classification. Neuropsychological development status was meas-ured according to pediatric-psychological mental test scale developed by Capital institute of pediatrics,Beijing and statistical a-nalysis was compared. Results The measurements of neuropsychological development showed the normal children behaved better than the children with CHDs(P < 0. 05). The simple CHDs group achieved better distribution of development quotient than complex CHDs group(P = 0. 032)and there was no difference between the normal control group and simple CHDs group (P = 0. 420). Multivariate regression analysis indicated that younger age at cardiac surgery,lower preoperative blood urea ni-trogen(BUN),higher preoperative creatinine(Cr)and prolonged duration of cardiopulmonary bypass(CPB)accounted for low-er scores in the test scale(P < 0. 05). Conclusion Distinct neuropsychological difficulties could be present especially in chil-dren with complex CHDs. Younger age at cardiac surgery,preoperative BUN,Cr and CPB duration were perioperative factors that were associated with long-time neuropsychological development.
