Objective:To investigate the effects of iron sucrose combined with recombinant human erythropoietin(EPO)on perioperative anemia and early functional recovery in elderly patients with intertrochanteric fractures.Methods:A retrospective comparative analysis was performed on 78 elderly patients who received PFNA treatment for intertrochanteric fractures in our hospital from July 2016 to December 2018.In the observation group, 40 cases were treated with iron sucrose combined with erythropoietin during the perioperative period.No perioperative intervention measures were taken for the control group.Hemoglobin(Hb)levels at 1, 3, 5, 7 days and before discharge and Harris scores of hip joints before surgery, 2 weeks and 3 months after surgery were compared between the two groups.Results:Hb levels were higher in the observation group than in the control group at 5 d[(98.8±8.6 g/L vs.92.2±8.5 g/L, t=3.389, P=0.001)]and 7 d[(105.4±8.9)g/L vs.(94.8±8.5)g/L, t=5.370, P=0.000]after surgery and before discharge[(115.4±8.6)g/L vs.(100.6±8.2)g/L, t=7.771, P=0.000]. Harris scores were higher in the observation group than in the control group 3 months after surgery(82.4±3.8 vs.75.8±2.5, t=8.933, P=0.000). Pearson' s correlation analysis showed that Hb levels at 5d and 7d after surgery were positively correlated with Harris scores at 3 months after surgery.Hb levels before discharge had an effect on Harris scores at 3 months after surgery. Conclusions:The combined administration of iron sucrose and EPO perioperatively can promote postoperative Hb recovery, reduce the incidence of anemia, accelerate early functional recovery and improve the quality of life in elderly patients with intertrochanteric fractures.

Objective To explore the level of Th2 type cytokines including IL-4, IL-10 and IL-13, and the immunoreg-ulation of cytokines in patients with neurocysticercosis. Methods Lymphocytes in patients with neurocysticercosis were separated from the blood sample with density gradient centrifugation and the total RNA was extracted by guanidine isothiocynate method. cDNA was synthesized by reversed transcription reaction. The target gene was then amplified by PCR. The PCR products were analyzed by electrophoresis. Results Results of RT-PCR showed that cytokines mRNA in lymphocytes of peripheral blcod were detected in 27 patients with neurocysticercosis but not in the other 3 cases. Among the positive cases, mRNA of IL-4, IL-10 and IL-13 was detected in 16, 17 and 14 cases respectively and mRNA of IL-4, IL-10 and/or IL-13 was detected in all the 27 cases. In the detection of lymphocytes in peripheral blcod of 10 healthy subjects, expression of IL-4 and IL-10 was found in only one case at low level. Conclusion The study revealed that Th2 associated cytokines were expressed at high level and the humoral immunocompetence was relatively strong in patients with neurocysticercosis.

Objective To study the clinical significance of vires infection and serum interleukin-2 (IL-2)Ievels in recurrent childhood idiopathic thrombocytopenic purpura(ITP).Methods The cytomegalovirus(CMV),epstein-Barrvirus(EBV)-adenovirus(ADV),herpesvirus(HSV)antibodies ISM and IL-2 levels were determined in the serum of 4 childhood with recurrent childhood ITP as well as in 40 normal controls with ELISA and RIA.Re-sults The CMV-lgM positive cases were 18,EBV-IgM were 14-ADV-IgM were 5,HSV-lgM were 3.In the controls,those were 3,2,1,and 0 respectively(P<0.05 or P<0.01).The serum IL-2(0.35±0.12)μg/L levels were sig-nificantly lower than those in the controls[(0.61±0.17)μ/L,P<0.05].Conclusion DNA virus antibodies and IL-2 levels can reflect virus infection and immune condition of diseases in recurrent childhood ITP.It is impor-rant to comprehend the mechanism of recurrent childhood ITP for guiding clinical treatment.

BACKGROUND:Recent studies indicate that osteolysis surrounding prosthesis is the main reason causing artificial joint loosening.The reason and development process of osteolysis surrounding prosthesis are not fully understood.OBJECTIVE:To observe the pathological changes of limiting membrane surrounding sterile loosened prosthesis of artificial hip ioint and compare that with cicatricial tissue surrounding internal fixation.DESIGN,TIME AND SETTING:Histological observation was done at The Second Hospital of Soochow University between September 2000 and December 2005.PARTICIPANTS:Limiting membrane surrounding prosthesis of eight artificial hip joints overhauled for loosening were removed during operation for pathological examination.METHODS:Specimens were fixed with 10%formaldehyde solution and embedded with paraffin,and were cut into sections,the sections were stained by hematoxylin-eosin(HE)staining and immunohistochemistry staining.The specimens were done bacterial culture.MAIN OUTCOME MEASURES:Histopathological changes.RESULTS:Wear particles,cellular proliferation and osteolytic factors were found in the limiting membrane surrounding loosening prosthesis.The bacterial culture results of the specimens were negative.CONCLUSION:Wear particles generated in the using process of prosthesis can activate osteolytic factors produced by inflammatory cells and is an important reason leading to sterile loosening of prosthesis.

Objective:To observe the effect of warm needling plus oral administration of rosuvastatin calcium tablets on blood lipids in cerebral infarction patients. Methods:A total of 125 eligible cases were randomly allocated into group A (n=42), group B (n=40) and group C (n=43). Cases in group A received warm needling plus oral administration of rosuvastatin calcium tablets, cases in group B received warm needling, whereas cases in group C received oral administration of rosuvastatin calcium tablets. Results:After treatment, the total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C) all dropped obviously in the three groups, with significant differences (allP<0.05), modified Barthel index (BI) scores all significantly rise (allP<0.05), and high-density lipoprotein cholesterol (HDL-C) remained unchanged (allP>0.05). After treatment, the changes of TC, TG and LDL-C in group A were significantly different from those in group B and group C (allP<0.05), while the changes showed no statistical significance between group B and group C (P>0.05). There were no between-group differences in HDL-C among the three groups (allP>0.05); the modified BI scores in groupA and groupB were significantly higher than that in group C (bothP<0.05), while there was no significant difference between group A and group B (P>0.05).After treatment, the total effective rate was significantly higher in group A than that in group B and group C (bothP<0.05), there was no significant difference between group B and group C (P>0.05). Conclusion:Warm needling and oral administration of rosuvastatin calcium tablets both can adjust blood lipids effectively in cerebral infarction patients with a similar therapeutic efficacy, while the effect gets better based upon combining both methods; acupuncture-moxibustion plays an important role in the recovery of nerve functions in cerebral infarction patients.

Objective To examine the application value of reticulocyte hemoglobin content (CHr)for diagnosing iron deficiency in premenopausal women.Methods The levels of CHr,hemoglobin (Hb), mean cellular volume(MCV),red cell distribution width (RDW) were measured on the ADVIA 120 (Bayer Diagnostics) automated hematology analyzer.Transferrin saturation (TS) and ferritin (SF) were measured on chemistry analyzer.Results CHr in iron deficiency without anemia group were significantly lower than that in the healthy control group (P＜0.01)and significantly higher than that in iron deficiency anemia group(P＜0.01).CHr in anemia of chronic disease group were significantly higher than that in iron deficiency anemia group(P＜0.01).Receiver operator characteristic curve (ROC) analysis in diagnosis of iron dificiency without anemia demonstrated that the area under the curve for CHr,SF,RDW,MCV,Hb were 0.872,0.798,0.721,0.713,0.677,respectively (P＜0.01).So CHr has a better overall sensitivity than SF,Hb,MCV and RDW in the diagnosis of iron deficiency without anemia.ROC also showed that the area under the curve for Hb,RDW,CHr,SF and MCV was 1.000,0.969,0.958,0.953 and 0.926,respectively (P＜0.01) in iron deficiency anemia.Conclusion CHr is the early and sensitive predictor of iron deficiency in premenopausal women,especially for the diagnosis of iron deficiency without anemia.
