Objective Toinvestigatetheeffectoffolicacidonplasmahomocysteine(Hcy)levels and vascular endothelial function in elderly cerebral infarction patients with hyperhomocysteinemia. Methods Thisstudywasaprospectivecontrolledtrial.Atotalof112elderlylacunarinfarction patients with high hyperhomocysteinemia admitted to the Department of Neurology,Nanjing Municipal Government Hospital from November 2012 to October 2013 were enrolled. The patients were divided into two groups according to the method of random number table. The patients of both groups received the conventional drug treatment of ischemic stroke at the same time. Fifty-six patients were in group A,and they were treated with folic acid 20 mg,once a day;56 patients were in group B,and they did not treat with folic acid. The Hcy levels on admission and after 24 weeks treatment were measured. Brachial artery flow-mediated endothelium-dependent dilation (FMD)was measured by high resolution ultrasound,and nitric oxide (NO), nitricoxidesynthase(NOS),andendothelin(ET)weredetectedatthesametime.Results Twenty-four weeks after treatment,the plasma Hcy level in group A was significantly decreased as compared with prior treatment (12. 2 ± 4. 2 vs. 22. 6 ± 3. 7μmol/L;P<0. 05),moreover,it was lower than the level of group B at the same period (12. 2 ± 4. 2 vs. 21. 8 ± 4. 0μmol/L;P <0. 05 ). The FMD level of group A was significantly higher than that of prior treatment and group B (11. 2 ± 3. 6 vs. 9. 2 ± 3. 3,9. 3 ± 3. 3;P<0. 05). The NO and NOS levels of group A at 24 weeks after treatment were significantly higher than those of prior treatment and group B at the same period (76. 2 ± 9. 4 vs. 49. 2 ± 9. 0,50. 0 ± 9. 1μmol/L,47. 6 ± 9. 5 vs.38. 4 ± 7. 5,37. 8 ± 8. 8 kU/L;P<0.05). The ET level of group A was decreased as compared with that of prior treatment and group B at the same period (81. 3 ± 20. 5 vs. 105. 6 ± 25. 2,105. 3 ± 21. 8 ng/L;P<0.05).NoadversereactionwasfoundduringthetreatmentingroupA.Conclusion Alargerdoseof folic acid can significantly reduce the plasma Hcy level,decrease the FMD level,and ameliorate vascular endothelial function in elderly cerebral infarction patients with hyperhomocysteinemia.

Recently more and more ophthalmologists selected a multifocal intraocular lens (IOL) for their cataract patient in order to get good unaided reading vision. Although the design of IOL have made a great progress, we are still dissatisfied compared with our natural crystal lens. Understanding the design theory and improving our surgery technique are basic for better utilization the multifocal IOL. Does the multifocal IOL reduce contrast sensitivity? Should we implant the multifocal IOL in pediatric cataract surgery? How can we deal with the residual refractive error after multifocal IOL implantation? In this editorial, we try to clarify these problems to make us select and use multifocal IOL better.

Objective:To observe the efficacy and safety of Qingpeng ointment in the prevention and treatment of chemotherapeutic phlebitis. Methods:Totally 72 patients with non-small cell lung cancer undergoing chemotherapy after pneumonectomy were randomly divided into control and observation groups. The control group was treated with the conventional therapy to prevent phlebitis, and on the basis of conrentional therapy the observation group was treated with Qingpeng ointment at the injection site and along with the vein be-fore the chemotherapy, at the beginning of the chemotherapy, during the chemotherapy and after the chemotherapy in the same day and on the next day. The treatment course was 3 days. The incidence of phlebitis, hierarchical cases, VAS score and pain duration between the groups were compared, and the adverse drug reactions were observed. Results:The pain degree and duration induced by phlebitis showed no significant differences between the groups(P>0. 05), while the pain degree and duration in the observation group were de-creased when compared with those in the control group. The incidence of phlebitis in the observation group was obviously lower than that in the control group with statistically significant difference (P <0. 05). No adverse reactions were found with the external use of Qingpeng ointment. Conclusion:Qingpeng ointment has certain efficacy with high safety in the prevention of tumor-chemotherapeutic phlebitis, which can improve patients’ compliance, and is worthy of promoted application in clinics.

Abstract Frailty is a clinical state characterized by increased vulnerability due to the decline of multiple organ functions. It is clinically manifested as slow movement, reduced activity, low energy level and involuntary weight loss. Frailty heightens the risk of disability, long-term hospitalization and mortality in the elderly when they face stressful events. Early assessment of frailty and personalized interventions can prevent and delay its progression, thereby reducing the occurrence of adverse events. This article reviews the literature on frailty published both domestically and internationally from January 2015 to January 2024. It provides an overview of the tools for assessing frailty in the elderly, such as the Clinical Frailty Scale, Frailty Index, Fried Frailty Phenotype, FRAIL Scale, and biological markers, and the management of frailty, including exercise, nutritional interventions, oral health management, and medication management, so as to provide the evidence for early assessment and intervention of frailty.

Objective To evaluate the usefulness of real-time three-dimensional transesophageal echocardiography(RT-3D-TEE)in cardiac valvular diseases.Methods Preoperative and postoperative RT-3D-TEE studies were performed in 32 patients who had undertaken cardiac valve repair or valvular replacement using Philips iE33 with X7-2 probe,and quantitative analysed the mitral structure in cases of mitral valve prolapse by using online QLAB7.0 quantitative analysis software.Results RT-3D-TEE can demonstrate the anatomicsl structure clearly,evaluate the function of cardiac valves precisely,and reveal details of type,position and extent of lesions vividly in surgical view.RT-3D-TEE helped correct misdiagnose in 2 cases,revised surgical plans in 3 cases,and guided implementation of remedial surgery in 1 case.Conclusions RT-3D-TEE can present images lively,and it can provide adequate information for preoperative diagnosis,aid the formulation of surgical plan and evaluate surgical effect.

Objective To study the quantification of MDR1 and WT1 gene expression in patients with de novo acute myeloid leukemia(AML)and to explore the role of these two genes in clinical drug resistance and their correlation with risk stratification. Methods A real time quantitative reverse transcriptase polymerase chain reaction method was established for detecting MDR1 and WT1 gene expression levels in 63 de novo AML patients.Resuits The expression of WT1 and MDR1 was significantly higher in de novo AML patients than in normal controls (P＜0.001).WT1 levels were significantly correlated with corresponding levels of MDR1 gene in de novo AML patients(P=0.004).Expression levels of WT1 and MDR1 gene were not associated with FAB subtype and risk stratication(P＞0.05).AML patients with FLT3-ITD mutations had a significantly higher WT1 expression level as compared to with those without(P＜0.05),on the contrary MDR1 expression was not associated with FLT3-ITD mutations(P＞0.05).Patients with co-expression of high levels of WT1 and MDR1 had a significantly lower complete remission rate after induction therapy than those with low levels(P＜0.05).Conclusion There is a positive correlation between MDR1 gene expression and WT1 gene expression in AML.Quantification of the two gene expression together is more effective for judgement of prognosis in AML.

This study is to investigate the anti-tumor activities of a novel cyclophosphamide derivate 4, 6-diphenyl cyclophosphamide (9b) in vivo and in vitro, and its possible mechanism of action. The inhibitory effects of 9b on human hepatoma cell line HepG2, human breast carcinoma cell line MCF-7 and human myeloid leukemia cell line K562 were measured by MTT assay in vitro. Cell cycle distribution and apoptotic rate were evaluated by flow cytometry. To evaluate the anti-tumor effect of 9b in vivo, mouse model bearing inoculated H22 tumor was established. The results indicated that 9b could inhibit the proliferation of HepG2, MCF-7 and K562 cells in a dose and time dependent manner. The ICo50 values of 9b were 32.34 micromol.L-1 to HepG2 cells, 87.07 micromol.L-1 to MCF-7 cells and 149.10 micromol.L-1 to K562 cells after incubation for 48 h. The results of flow cytometry indicated that after being treated for 48 h with different concentrations of 9b, the ratios of HepG2, MCF-7 cells at the Go/G1 phase and K562 cells at the G0/Gl phase and G2/M phase increased significantly compared with control group, and the apoptotic rate increased with the increase of the concentration of 9b. 9b could significantly reduce tumor weight of H22 solid tumor mouse model in vivo. To summarize, 9b showed significantly anti-tumor activity in vivo and in vitro, of which the mechanism might be associated with the change of cell cycle distribution and induction of tumor cell apoptosis.

OBJECTIVETo compare the difference in depression relief in the treatment of depressive disorder at the acute stage between the combined therapy of acupuncture and 5-HT (5-hydroxytryptamine) selective serotonini reuptake inhibitors (SSRIs) and the single application of SSRIs and explore the impact on the imbalance of 5-HT and TH1/TH2.

METHODSNinety cases of depressive disorder at the acute stage were randomized into a combined therapy group and a medication group, 45 cases in each one. In the medication group, SSRIs were prescribed forl oral administration, once or twice a day, continuously for 4 weeks. In the combined therapy group, on the basis of treatment as the medication group, acupuncture was combined. The main acupoints were Baihui (GV 20), Yintang (GV 29), Shenting (GV 24), Fengchi (GB 20), Dazhui (GV 14) and Sishencong (EX-HN 1), once every two. days, continuously for 4 weeks. Before treatment, and after the 1st, 2nd and 4th weeks of treatment, the Hamilton depression scale (HAMD) was used to evaluate the depression severity. Separately, before and after the 4 weeks of treatment, the levels of serum 5-HT, interleukin-1 beta (IL-1β), interleukin-6 (IL-6), interleukin-4 (IL-4) and interleukin-10 (IL-10) were determined and compared with those in 45 cases of the healthy group.

RESULTSHAMD score was reduced in the 1st, 2nd and 4th weeks of treatment as compared with that before treatment in the combined therapy group (all P<0 01). HAMD score was reduced in the 2nd and 4th weeks of treatment as compared with that before treatment in the medication group (all P<0. 01). HAMD scores in the combined therapy group were lower than those in the medication group in the 1st, 2nd and 4th weeks of treatment (all P< 0. 01). Before treatment, in the combined therapy group and the medication group, the levels of serum 5-HT, IL-4 and IL-10 were all lower than those in the healthy group (all P<0. 01); the levels of IL-1β and IL-6 were higher than those in the healthy group (all P<0. 01). In the combined therapy group and the medication group, the levels of 5-HT, IL-4 and IL-10 in 4 weeks of treatment were all increased as compared with those before treatment (all P<0. 01), and the levels of IL-1β and IL-6 were lower than those before treatment (all P<0. 01). In the combined therapy group, the levels of IL-1β and IL-6 in 4 weeks of treatment were lower than those in the medication group, and the levels of 5-HT, IL-4 and IL-10 were higher than those in the medication group (P<0. 01, P< 0. 05).

CONCLUSIONThe combined therapy of acupuncture and SSRIs achieves much quicker and more effective re-' sult for relieving depression in the patients of depressive disorder as compared with simple oral administration of' SSRIs, and much more contributes to adjust the imbalance of serum 5-HT and TH1/TH2.
