1.A very high frequency index of heart rate variability for evaluation of left ventricular systolic function and prognosis in chronic heart failure patients using five-minute electrocardiogram
Journal of Geriatric Cardiology 2009;6(4):213-217
Objective Anovel index based on frequency-domain analysis of heart rate variability (HRV) was tested on patients with reduced left ventricular systolic function.This index,namely VHFI,was defined as the very high frequency (VHF) component of the power spectrum normalized to represent its relative value in proportion to the total power minus the very low frequency component.Methods Patients (n=130) were divided into a study group,consisting 66 patients with decreased left ventricular systolic function,and a control group,consisting 64 patients with normal heart structure and function and without severe coronary artery stenosis (<50%).Results VHFI in the study group was significantly higher than that in the control group (19.17±13.35 vs 11.37±10.77,P<0.001).Cardiac events occurred in 18 patients during follow-up (33.34±3.26 months).Defining the positive test as VHFI =15 and negative test as VHFI <15,achieved a sensitivity of 57.58% and a specificity of 78.13% for predicting decreased left ventricular systolic function,and achieved a sensitivity of 66.67% and a specificity of 64.29% for predicting cardiac events.Univariate Cox regression analysis showed that positive VHFI test was an independent variable in predictive cardiac events.Conclusions The results suggest that VHFI is a useful tool for quick evaluation of left ventricular systolic function and prediction of prognosis.
2.Effects of self-made Yishen Antai Decoction combined with progesterone in the treatment of patients with recurrent spontaneous abortion and the effect on pregnancy outcomes and blocking antibodies
Chinese Journal of Biochemical Pharmaceutics 2017;37(9):104-105,107
Objective To investigate the effects of self-made Yishen Antai Decoction combined with progesterone in the treatment of recurrent spontaneous abortion (RSA) and the effect on pregnancy outcomes and blocking antibodies (BA). Methods 100 cases of patients with RSA were randomly divided into the observation group and the control group, 50 cases in each group. The control group was treated with progesterone and on the basis, the observation group was additionally treated with self-made Yishen Antai Decoction. Both groups were intervened till 12 weeks of gestation, and the clinical curative effect was evaluated. Results The total effective rate of treatment, the success rate of pregnancy and the positive rate of blocking antibody (BA) showed significant differences between the observation group and the control group (P< 0.05). After treatment, the total TCM symptom score and serum levels of interleukin-2 (IL-2) and interferon-γ (IFN-γ) were significantly lower while interleukin-10 (IL-10) level was significantly higher in the observation group than the control group (P< 0.05). There were no serious adverse reactions in the two groups. Conclusion Self-made Yishen Antai Decoction is effective and safe in the treatment of RSA. It can significantly improve the success rate of pregnancy and the positive rate of BA, which may be associated with the regulation of IL-2, IL-10 and IFN-γ levels.

Objective To make an evidence-based rehabilitation plan for a patient with osteogenesis imperfecta after external fixation. Methods Based on a comprehensive assessment for the patient's condition, the clinical problems were listed. Related articles were searched from National Guideline Clearinghouse (NGC), The Cochrane Library, PubMed, CBM, CNKI and Wanfang databases. And the reference list of each eligible article was also included. Finally the optimum rehabilitation program was designed with optimal clinical evidence, patient's conditions and relatives' willingness. Results 1 randomized controlled trial and 4 case reports were included. A progressive exercise program was developed and implemented. No new fractures occurred during the intervention. Muscle strength, gait, activities of daily living had been greatly improved. 20 weeks later, the Berg score was 43 and the Barthel index was 80. Conclusion The progressive rehabilitation exercise program developed from evidence-based practice is safe, effective and feasible.
4.Advances on internal fixation treatment for femoral neck fracture in elderly patients.
China Journal of Orthopaedics and Traumatology 2014;27(8):706-708
Compared with hip replacement, internal fixation in the treatment of the elderly femoral neck fracture, especially the application of cannulated screws, is minimally invasive, easy to operate and economical. In recent years, it becomes the research focus in the field of orthopedic clinical research. However, configuration of cannulated screws is still controversial. Most clinicians believe that three cannulated screws being placed in parallel in an inverted triangle configuration is better than that in a triangular configuration in biomechanics and clinical effect. Nonparallel strong oblique nailing technique allows the screws to share more weight to reduce postoperative complications, so that it is more suitable for elderly patients with osteoporosis. However, the related complications of internal fixation such as nonunion, femoral neck shortening and other problems are still the focus of domestic and foreign scholars. Issues about how to control the indication of internal fixation surgery, understand related factors of the complications, and prevent complications are required to be further explored.

5.Feeding intolerance in preterm infants
International Journal of Pediatrics 2015;(4):385-388
Feeding intolerance in preterm infants,which is an important issue that the neonatal pediatri-cians have to work out,leads to malnutrition of early preterm infants and growth restriction which have an impact on later behavioral and cognitive outcomes. Feeding intolerance is related to the immature of gastrointestinal function,perinatal asphyxia,infection and other diseases. Minimal enteral feeding,prokinetic agents and supple-mentation of the enteral probiotics,are used generally,but at present there is no guidelines for the prevention and treatment.
6.Measurement of femoral neck shortening after cannulated screwing for elderly femoral neck fractures and the effect of shortening on hip function
Chinese Journal of Orthopaedic Trauma 2014;16(8):651-655
Objective To explore the measurement of femoral neck shortening (FNS) after cannulated screwing for elderly femoral neck fractures and the effect of FNS on hip functional outcome.Methods Totally 214 elderly patients with femoral neck fracture were included in this study who had been treated by fixation with cannulated screws from June 2007 to October 2013.They were 71 males and 143 females,with an average age of 77.2 years.According to Garden classification system,65 cases were types Ⅰ and Ⅱ (undisplaced fractures),and 149 types Ⅲ and Ⅳ (displaced fractures).The postoperative X-ray and follow-up X-ray films were compared to observe whether the trailing end of screw shaft was exposed to the outer cortex of the proximal femur.We chose the screw which had the longest exposure of trailing end to measure the length of the exposed screw shaft as the length of FNS.FNS indexes were defined according to the ratio of the length of exposed screw shaft to the thickness of screw head.FNS degree 1:< 1 screw head; FNS degree 2:1 to 2 screw heads; FNS degree 3:> 2 screw heads.The relationships of the FNS length respectively with thefemur length decrease and Harris scores of hip functional outcome were analyzed statistically.Results FNS occurred in 78 cases,giving an incidence of FNS of 36.4% (78/214).Of them,12 cases (15.4%)were defined as degree 1,24 cases (30.8%) as degree 2,and 42 cases (53.8%) as degree 3.There was a significant positive correlation between the FNS length and the femur length decrease(r =0.919,P =0.000).The average Harris score at 12 months postoperation for 180 cases was 77.3 points (ranging from 32 to 98 points).The average Harris score for those with FNS was significantly lower than that for those without FNS (t =9.904,P =0.000).There was a significant negative correlation between the FNS length and Harris scores (r =-0.707,P =0.000).Conclusions Our measurement of FNS and FNS indexes are easy to be used in clinic.Severe FNS can influence the function of hip joint.
7.Pay attention to the long-term toxicities of therapy on lymphoma
Journal of Leukemia & Lymphoma 2010;19(11):641-645
There are an increasing number of survivors of successful treatment of lymphomas over the past 30 years. Although these survivors may be cured of their lymphoma, long-term morbidity and mortality are associated with late toxicities of the treatment. Identification of these late complications will lead to strategies to manage them when they occur and hopefully decrease the risk of their development. Secondary malignancies and treatment associated cardiovascular disease are the leading causes of late morbidity and mortality.Musculoskeletal difficulties, endocrine abnormalities, including sterility and thyroid disease, and heart and lung damage, have also been seen.The late complications of primary treatment of lymphoma and autologous stem cell transplantation usually for relapsed disease are the subjects of this paper.

Pharmacogenomics is defined as the study of the association between genetics and drug response. This review includes basic concepts of pharmacogenomics, heterogeneity of hypertension and antihypertensive drug responses, genes associate with drug metabolism, and individualized drug therapy. The knowledge of genes that influence the pharmacodynamic determinants of blood pressure response to antihypertensive medications has the potential to provide new insights not only into molecular mechanisms influencing drug response, but also into the role that these genes may play in determining interindividual differences in blood pressure level and the occurrence of hypertension.
9.Changes of vascular endothelial growth factor and tumor necrosis factor-α levels in serum of patients with primary hepatocellur carcinoma
Chinese Journal of Primary Medicine and Pharmacy 2009;16(2):227-228
Objective To investigate vascular endothelial growth factor(VEGF) and TNF-α levels in the serum of patients with primary hepatocellur carcinoma(HCC),and to evaluate their relevance with the development and metastasis of HCC.Methods VEGF and TNF-α levels in serum were examined by enzyme linked immunosorbent assay(ELISA) technology in 87 patients with HCC and 10 healthy individuals.Results Serum VEGF and TNF-α,levels in HCC patients were significantly higher than that in the contorl group.In addition,HCC patients infected with hepatitis virus(including HBV and HCV) showed a remarkable elevation in serum VEGF and TNF-α levels.The VEGF and TNF-α levels in HCC with metastasis were also higher than those without metastasis.Conclusion The serum VEGF and TNF-α levels in HCC patients might serve as the pivotal biological indices that could reflect HCC progressien and metastasis.
