Long Noncoding RNA Cytoskeleton Regulator RNA Suppresses Apoptosis in Hepatoma Cells by Modulating the miR-125a-5p/ HS1-Associated Protein X-1 Axis to Induce Caspase-9 Inactivation

Background/Aims@#The involvement of long noncoding RNAs in the carcinogenesis of hepatocellular carcinoma (HCC) has been well documented by substantial evidence. However, whether cytoskeleton regulator RNA (CYTOR) could affect the progression of HCC remains unclear. @*Methods@#The relative expression of CYTOR, miR-125a-5p and HS1-associated protein X-1 (HAX-1) mRNA in HCC cells were determined via quantitative real-time polymerase chain reaction. The viability of treated HCC cells was measured by Cell Counting Kit-8 assay. Cell apoptosis was estimated by flow cytometry analysis, assessment of caspase-9 activity and terminal deoxynucleotidyl transferase dUTP nick-end labeling staining, and Western blot of apoptosisrelated proteins. The interplay between CYTOR or HAX-1 and miR-125a-5p was validated by dual-luciferase reporter assay. @*Results@#CYTOR was upregulated and miR-125a-5p was downregulated in HCC cells. CYTOR silencing inhibited cell proliferation and promoted cell apoptosis in HepG2 and SMMC-7721 cells.miR-125a-5p was sponged and negatively regulated by CYTOR, and HAX-1 was directly targeted and negatively modulated by miR-125a-5p. Overexpression of miR-125a-5p enhanced the repressive effects of CYTOR knockdown on HCC cells, and knockdown of HAX-1 enhanced the inhibitory effects of miR-125a-5p mimics on HCC cells. @*Conclusions@#CYTOR silencing facilitates HCC cell apoptosis in vitro via the miR-125a-5p/HAX-1 axis.

Clinical characteristics analysis of adult femoral neck fracture: a retrospective hospital-based study / 中华骨科杂志

Objective:To analyze the clinical characteristics of patients with femoral neck fracture in Tianjin Hospital.Methods:Data of femoral neck fracture patients discharged from Tianjin Hospital from January 1, 2016 to December 31, 2017 were retrospectively analyzed. The gender, age, fracture type, injury mechanism and treatment method were collected.Results:Total of 2,150 eligible patients including 736 males and 1414 females were selected. There were significant differences in the gender distribution in different age groups ( χ2=91.63, P<0.001). Among young patients, males were more than females, while among middle-aged and elderly patients, females were more than males. The main type of fracture was displaced type (75.56%, 1,646/2,150), the displaced rate was the lowest in young patients (55.17%, 64/116), while it was the highest in old patients (81.91%, 1,159/1,415). The main injury mechanism of the three age groups were falls [young 61.21% (71/116), middle 80.29% (497/619), eldly 91.24% (1,291/1,415)]. There was a significant difference in the treatment methods between different age groups ( χ2=1,057.11, P<0.001). The main treatment method for young and middle-aged patients was internal fixation, no matter whether the fracture was displaced or not. The proportion of undisplaced patients with internal fixation (86.22%, 169/196) was higher than that of displaced patients with internal fixation (62.88%, 266/423) in middle-aged group ( χ2=34.93, P<0.001). In the elderly, more patients used internal fixation in undisplaced group, while more patients used hemiarthroplasty in displaced group. The age of old femoral neck fracture (median age was 74) was older than that of fresh fracture (median age was 70) ( Z=-2.777, P=0.005). And the displaced rate of patients with old femoral neck fracture (92.41%, 73/79) was higher than that of the fresh ones (75.95%, 1,573/2,071)( χ2=11.48, P=0.001). The patients with old femoral neck fracture usually adopt total hip replacement, while the proportion of three kinds of operation (internal fixation, hemiarthroplasty, total hip replacement) were similar among the fresh ones, and the internal fixation was the most. Conclusion:Femoral neck fracture is the most common in elderly women. The patients with displaced fracture are more than that with undisplaced fracture. Falling is the main injury mechanism in both young and old people. Internal fixation is commonly used in young and middle-aged patients, while arthroplasty is often used in elderly patients.

The role of coupler perfusion in transrectal ultrasound in the diagnosis of T-stage rectal cancer / 中华超声影像学杂志

Objective:To investigate the role of coupler perfusion in transrectal ultrasound in the diagnosis of preoperative T staging of rectal cancer.Methods:A retrospective analysis of the preoperative clinical data of 132 patients with rectal cancer in the People′s Hospital of Inner Mongolia Autonomous Region from June 2015 to November 2020. According to whether or not the patients agreed to coupler perfusion before ultrasound examination, they were divided into 2 groups, namely the perfusion group 69 cases and the non-perfusion group of 63 cases, with postoperative pathology as the gold standard, and compared with magnetic resonance imaging(MRI) to evaluate the accuracy of the 2 groups and MRI in the T staging of rectal cancer.Results:The total coincidence rates of the coupling agent perfusion group, non-perfusion group and MRI group for the diagnosis of rectal cancer T staging were 89.9%, 76.2% and 87.9%, respectively, and the difference among the three methods was statistically significant (χ 2=6.096, P=0.047). The diagnostic sensitivity of the coupling agent perfusion group for T1 stage was 96.0%, which was higher than 61.5% of the non-perfusion group and 92.3% of the MRI ( P=0.010). The specificity of the perfusion group for the diagnosis of T2 stage was 95.7%, higher than the non-perfusion group and MRI ( P=0.037), the positive predictive value of the perfusion group for T2 stage was 90.9%, which was higher than the non-perfusion group and MRI ( P=0.035). The diagnostic accuracy of the perfusion group for T2 stage was 94.2%, higher than the non-perfusion group and MRI (χ 2=7.070, P=0.029). There were no statistically significant differences in diagnostic sensitivity, specificity, positive predictive value, negative predictive value and accuracy among the perfusion group and the non-perfusion group and the MRI for T3 and T4 (all P>0.05). Conclusions:Coupled-agent perfusion makes it convenient and fast for intracavity ultrasound to diagnose T staging of rectal cancer, and the diagnostic efficiency is comparable to MRI. In particular, it can be used as a highly reliable imaging method for T1 and T2 rectal cancer.

Analysis of etiology and cytokines of benign infantile convulsions with mild gastroenteritis / 中国小儿急救医学

Objective:To investigate the pathogenic distribution of benign infantile convulsions with mild gastroenteritis(BICE)and explore the relevance of serum cytokines and BICE.Methods:Eighty BICE infants admitted in Inner Mongolia Maternal and Child Health Hospital from January 2017 to December 2019 were selected as BICE group, and 80 mild gastroenteritis infants without convulsion attack were selected as control group during the same period.Fluorometric real-time PCR was used to detect the pathogen of enterovirus.Serum cytokines including interleukin(IL)-6, tumor necrosis factor(TNF)-α, IL-8 and soluble interleukin-2 receptor(SIL-2R)were detected by using chemiluminescence method.The relevance of frequency and duration of convulsion in infants with BICE and the indicators above were analyzed.Results:Rotavirus infection was the main cause of BICE during the study period in this region.Among 80 cases in the BICE group, rotavirus positive infants accounted for 38.8%(31/80) and norovirus positive infants accounted for 10.0%(8/80). The levels of IL-6, IL-8 and SIL-2R in the BICE group were prominently higher than those in the control group( P<0.05); the difference of TNF-α level between two groups had no statistical significance( P>0.05). The levels of IL-6, TNF -α, IL-8, SIL-2R in the group with convulsion attack times ≥ 2 and convulsion duration ≥5 min were higher than those in the group with convulsion attack times<2 and convulsion duration<5 min( P<0.05). The frequency and duration of convulsions were positively correlated with the levels of IL-6, TNF -α, IL-8 and SIL-2R( P<0.05). Conclusion:Rotavirus is the main pathogen of BICE in this region.There is immunologic imbalance in children with BICE, especially the changes of IL-6 and SIL-2R levels, which may provide effective cytological and experimental data evidence for judging progression and prognosis of the disease.

A multicenter clinical study on 1 138 cases of invasive pneumococcal disease in children from 2012 to 2017 / 中华儿科杂志

Objective@#To explore the clinical features, the serotype distribution and drug resistance of the isolates in patient with invasive pneumococcal disease (IPD).@*Methods@#By retrieving the laboratory information system in 18 children′s hospitals from 2012 to 2017, the children with IPD were enrolled. Streptococcus pneumoniae (Spn) must be isolated from the sterile sites (blood, cerebrospinal fluid, hydrothorax and joint effusion etc.). The clinical characteristics, serotype, drug resistance, treatment and prognosis were reviewed and analyzed. According to the telephone follow up results, the patients were divided into death group and recovered group. The index as an independent risk factor of mortality was demonstrated by multivariate logistic regression analysis.@*Results@#There were 1 138 children with IPD, including 684 male and 454 female. The proportion of male to female was 1.5∶1. The age ranged from one day to 16 years. The median age was 1 year 3 month. The majority was under 5 years of age (89.3%, n= 1 016), especially under 2 years of age (61.9%, n=704). In all cases, 88.2% (n=1 004) were community acquired infection. The infections included meningitis (n=446, 39.2%), pneumonia with bacteremia (n=339, 29.8%), and bacteremia without focus (n=232, 20.4%). Underlying diseases were found in 242 cases (21.3%). Co-infections were determined in 62 cases (5.4%) with mycoplasma, 27 cases (2.4%) with adenovirus and 34 cases with influenza virus (3.0%). The penicillin insensitivity (PNSP) rates in meningitis and non-meningitis isolates were 69.5% (276/397) and 35.9% (221/615), respectively. There were 81 strains serotyped, in which 93.8% (76/81) were covered by 13-valent protein-polysaccharide conjugate vaccine (PCV13). In the 965 patients who were followed up by phone call, 156 cases (16.2%) were confirmed dead. The independent risk factors for the death were under 2 years of age (OR=2.143, 95%CI 1.284-3.577, P=0.004), meningitis (OR=3.066, 95%CI 1.852-5.074, P<0.01), underlying disease (OR=4.801, 95%CI 2.953-7.804, P<0.01), septic shock(OR=3.542, 95%CI 1.829-6.859, P<0.01), disseminated intravascular coagulation (DIC) (OR=4.150, 95%CI 1.468-11.733, P=0.007), multiple organ failure (OR=12.693, 95%CI 6.623-24.325, P<0.01) and complications of central nervous system (OR=1.975, 95%CI 1.144-3.410, P=0.015).@*Conclusions@#Most children with IPD were under 5 years of age, having underlying diseases and acquired the infection in community. The independent risk factors for death were under two years old, meningitis, underlying diseases and multiple organ failure. The problem of drug resistance was severe. The universal immunization of PCV13 would be effective to prevent IPD in Chinese children.

Overexpression of constitutively active MAP3K7 in ameloblasts causes enamel defects of mouse teeth.

OBJECTIVE: Compelling evidence suggests that mitogen-activated protein kinases (Mapks) play an important role in amelogenesis. However, the role of transforming growth factor (TGF)-ß-activating kinase 1 (Tak1, Map3k7), which is a known upstream kinase of Mapks, during amelogenesis remains to be determined. The aim of this study was to investigate the possible involvement of Map3k7 in amelogenesis. DESIGN: We generated transgenic mice that produced constitutively active human MAP3K7 (caMAP3K7) under the control of amelogenin (Amelx) gene promoter. Radiography and micro-computed tomography (µCT) analysis was used to detect the radio-opacity and density of the teeth. The enamel microstructure was observed with a scanning electron microscope. Histological analysis was used to observe the adhesion between ameloblasts and residual organic matrix of the enamel. Quantitative real-time polymerase chain reaction (qRT-PCR) was used to analyze the expression of enamel matrix protein. RESULTS: The enamel of mandibular molars in caMAP3K7-overexpressing mice displayed pigmentation and a highly irregular structure compared with the wild type littermates. Teeth of transgenic animals underwent rapid attrition due to the brittleness of the enamel layer. The microstructure of enamel, normally a highly ordered arrangement of hydroxyapatite crystals, was completely disorganized. The gross histological appearances of ameloblasts and supporting cellular structures, as well as the expression of the enamel protein amelotin (Amtn) were altered by the overexpression of caMAP3K7. CONCLUSIONS: Our data demonstrated that protein expression, processing and secretion occurred abnormally in transgenic mice overexpressing caMAP3K7. The overexpression of caMAP3K7 had a profound effect on enamel structure by disrupting the orderly growth of enamel prisms.

Objective To investigate the clinical effects of high restrictive anti-dislocation prosthesis total hip arthroplasty(THA)in treating elderly femoral neck fracture patients with hemiplegia.Methods From June 2015 to January 2017,Fortythree elderly femoral neck fracture patients with hemiplegia were treated with CombiCup THA system.There were 15 males and 28 females with an average age of 71.5±5.6 years (60-84 years).The left side was involved in 20 cases,while the right side in 23 cases.There were 15 cases with Garden Ⅲ type and 28 cases with type Ⅳ.Lower limb muscle strength grade were 20 cases in grade 3,19 cases in grade 4,and 5 cases in grade 5.Sixteen cases walked independently before injury,while 27 of them walked with the aid of crutches.The duration between injuries to operation ranged from 2 days to 5 days.The size of the prosthesis and offset distance were recorded by template technique pre-operation.The appropriate type of prosthesis was selected to restore the offset and to reconstruct the abductor muscle arm,according to the actual measurement in the operation and the preoperative plan.Based on the bone mineral density and medullary cavity morphology,biological or cemented femoral stem prosthesis was selected.The quality of the implant and the length of both lower limbs were evaluated by pelvic X-ray immediately after operation.The patients were followed-up at 2 weeks,1 months,2 months,3 months,6 months,1 and 2 years.Functional exercise guidance and complications were recorded at the follow-up duration.At the last follow-up,the hip function and limb function were evaluated according to the Harris score and Fugl-Meyer motor function assessment respectively.Results Based on pelvic X-ray evaluation after operation,all prosthesis position were favorable with the average angle of acetabular abduction 45.1±2.3 degrees and the length difference of both limbs less than 5 mm (average 2.2±0.8 mm).The follow-up duration ranged from 6 to 24 months with an average of 11.2±3.5 months.There was no complication such as prosthesis dislocation and infection.Deep venous thrombosis in calf occurred in 3 patients at 2 days after operation,who underwent recanalization after thrombolysis.At the last follow-up,the average score of Harris hip function and Fugl-Meyer were 90.2±3.8 (77 to 96) and 97.1±2.5 (83 to 100),respectively.No dislocation,infection,loosening,subsidence and osteolysis phenomenon was found during the follow-up.Conclusion The elderly patients with Garden type Ⅲ or Ⅳ femoral neck fractures accompanied with hemiplegia can be treated with anti-dislocation prosthesis THA.It does have the advantages of low dislocation rate and imoroved hemiolegic limb function.

Application of next generation sequencing technology in Mendelian movement disorders / 中南大学学报(医学版)

Next generation sequencing (NGS) has developed very rapidly in the last decade. Compared with Sanger sequencing, NGS has the advantages of high sensitivity and high throughput. Movement disorders are a common type of neurological disease. Although traditional linkage analysis has become a standard method to identify the pathogenic genes in diseases, it is getting difficult to find new pathogenic genes in rare Mendelian disorders, such as movement disorders, due to a lack of appropriate families with high penetrance or enough affected individuals. Thus, NGS is an ideal approach to identify the causal alleles for inherited disorders. NGS is used to identify genes in several diseases and new mutant sites in Mendelian movement disorders. This article reviewed the recent progress in NGS and the use of NGS in Mendelian movement disorders from genome sequencing and transcriptome sequencing. A perspective on how NGS could be employed in rare Mendelian disorders is also provided.

Objective To investigate the therapeutic effect of microinvasive PGLA thread embedding on neck pain due to cervical spondylosis. Method One hundred and five cervical spondylosis patients with complaints of neck pain were randomly allocated to three groups, 35 cases each. The thread embedding group received PGLA thread embedding therapy;the control group, acupuncture with thread-embedding needles (without thread embedding);the acupuncture group, conventional acupuncture. Result There was a significant difference in the relief of symptoms and signs between the thread embedding or acupuncture group and the control group (P<0.05). There were statistically significant pre-/post-treatment differences in the VAS score and the PPI score in the thread embedding and acupuncture groups (P<0.05). There were statistically significant post-treatment differences in the above scores between the thread embedding or acupuncture group and the control group (P<0.05). The total efficacy rate was 17.1% in the control group, 77.1%in the acupuncture group and 94.3%in the thread embedding group. The total efficacy rate was significantly higher in the thread embedding group than in acupuncture and control groups. Conclusion The therapeutic effect on neck pain due to cervical spondylosis is produced by PGLA thread stimulation of the acupoints and not by simple injurious stimulation with thread-embedding needles. PGLA thread embedding has a marked therapeutic effect on neck pain due to cervical spondylosis.

Antitumor effects and immune regulation activities of a purified polysaccharide extracted from Juglan regia.

A water-soluble polysaccharide, named as JRP1, was extracted and fractioned from the epicarp of immature fruit of Juglans mandshurica Maxim. The determination of the monosaccharide composition in JRP1 with gas chromatography (GC) showed that JRP1 was composed of Gal (43.1%), Glu (23.6%), Ara (16.2%), Rha (9.8%) and Fru (7.3%). The results in vitro showed that 25, 50 and 100 µg/mL of JRP1 could present a significant inhibition on the growth of S180 cells, and furthermore, a significant improvement on the proliferation ability of lymphocytes and the phagocytic activity of macrophages. The results in vivo showed that compared with those in the control group, the inhibition rates of different doses of JRP1 on S180 cells in the tumor-bearing mice were 35.3%, 40.6% and 48.1%, respectively, and serum immune cytokine levels such as IL-2, TNF-α and IFN-γ were significantly improved. Our results confirm that JRP1 has the activities of effective antitumor and immunomodulatory function.

The neck disability index (NDI) was compared.</p><p><b>RESULTS</b>The score of symptoms and function after treatment was increased apparently in the deep-layer embedding group (P < 0.05), which was increased more apparently as compared with those in the shallow-layer embedding group and the middle-layer embedding group (both P < 0.05). PRI, VAS and PPI after treatment were all reduced apparently as compared with those before treatment in the deep-layer embedding group and the middle-layer embedding group (all P < 0.05), which were reduced more remarkably than the shallow-layer embedding group (all P < 0.05). After treatment, the scores of NDI in the deep-layer embedding group and the middle-layer embedding group, were reduced apparently as compared with those before treatment (both P < 0.05), and that in the deep-layer embedding group was reduced more remarkably as compared with the shallow-layer embedding group and the middle-layer embedding group after treatment (both P < 0.05).</p><p><b>CONCLUSION</b>In the acupoint embedding treatment of cervical spondylosis of nerve root type, the efficacy is different apparently in terms of the implantation depth. The deep-layer implantation, meaning to the multifidus muscle layer is more conductive to the treatment of cervical spondylosis.</p>

Preliminary study on depth of embedded catgut and qi arrival at cervical Jiaji (EX-B 2) under ultrasound guidance / 中国针灸

<p><b>OBJECTIVE</b>To explore the relationship between the needling sensation of catgut embedding therapy and the depth of embedded catgut so as to improve the safety of the needle insertion and catgut implantation of the therapy.</p><p><b>METHODS</b>Twenty healthy adults were selected. Under the ultrasound, the structure of the cervical Jiaji (EX-B 2) was observed. In the ultrasound guidance, the catgut was embedded. The two-dimensional imaging method was adopted to observe the anatomic structure and the procedure of needle insertion at the cervical Jiaji (EX-B 2). The high-frequency ultrasound was used to collect the images at Jiaji (EX-B 2) of C5 and determine the depths from the skin surface to the different layers of the point. Additionally, the visual analogue scale (VAS) was adopted to score the needling sensations when the needle inserted at different layers. The persistent sensation duration in the local area was followed continuously.</p><p><b>RESULTS</b>Under the ultrasound, the anatomic structure and tissue layers of cervical Jiaji (EX-B 2) were displayed clearly. The difference was significant in the average depth from the skin surface to the subcutaneous tissue, trapezius, splenius capitis, semispinalis capitis, semipinalis cervicis, multifidus and vertebral arch between the males and females (all P<0. 01). During the needle insertion, the sensations were apparently different when the implantation went to different layers. The qi arrival presented when the catgut was embedded to the trapezius, splenius capitis, semispinalis capitis, semipinalis cervicis and multifidus. But the distending pain was the most significant when in the myofascial. Commonly, the embedded catgut 2. 5 cm in length may be implanted deeply to the multifidus and the local needling sensation lasted averagely for (72. 0 ± 10. 2) h. Conclusion Under the ultrasound guidance, the depth of embedded catgut is clearly displayed at cervical Jiaji (EX-B 2). The needle insertion and the implanted material are visible, and the relationship between qi arrival and the layer of needle insertion is determined. The accuracy and safety of minimally invasive catgut embedding therapy is improved in the treatment of cervical spondylosis.</p>

Inhibition of Glioblastoma Cell Growth In Vitro and In Vivo by Brucine, a Component of Chinese Medicine.

Glioblastoma multiforme (GBM) is one of the most common glial cell tumors and has drawn more and more attention in the clinic in recent years. Brucine has been reported to significantly suppress gastric cancer, lung cancer, and prostate cancer growth in vivo by inducing cell apoptosis. Here, the effects of brucine on U251 human glioma cell growth were investigated in vitro by cell proliferation assay, FACs, and qPCR in a xenograft tumor model. Treatment with brucine reduced the expression of BCL-2 and cyclooxygenase-2 (COX-2), while upregulated BAX expression in U251 human glioma cells resulted in reduced glioma cell survival rate and inhibited the growth of xenograft tumors. We concluded that brucine has a suppressive effect on U251 human glioma cells in vitro and in vivo, which could help in understanding the role of brucine in glioma cells and guiding drug use in the clinic.

Objective To investigate the clinical results and related key points of surgical treatment for Hawkins Ⅲ talus neck fractures.Methods From March 2005 to March 2010,26 patients with Hawkins Ⅲ talus neck fracture were treated and 21 of them were followed,including 13 males and 8 females,with an average age of 37.6 years.The fractures occurred on the left side in 11 patients and on the right side in 10patients.The mechanism of injury included high falling injury in 13 patients,traffic accident injury in 7 patients and rolling down injury in 1 patient.Five cases were closed fractures and 6 cases were open fractures.A bilateral approach,the medial and lateral approaches,was used to perform the operation with cannulated screw fixation in emergency.After external fixation in functional position for 6 weeks without loading,ankle joints were allowed to take exercise with hinge brace and to bear partially basing on plain radiograph 12-16weeks later.The weight-bearing should be adjusted with follow-up.Functional results were assessed according to AOFAS (American Orthupaedic Foot and Ankle Society,AOFAS)score.Results The average duration of follow-up was 36.6 months (range,6-60 months).All fractures gained union and the average union time was 4.5 months.The average AOFAS score was 78.6.There were 4 cases in excellent results,10 in good,5 in fair and 2 in poor.The overall excellent and good rate was 67.8％.Traumatic arthritis occurred in 13 cases and avascular necrosis in 5 cases.Conclusion The effect of surgical treatment for Hawkins Ⅲtalus neck fracture via a bilateral approach is satisfactory.

Prevalence of human papillomavirus infection in women with uterine cervical cancer in Wenzhou / 中华临床感染病杂志

Objective To investigate the prevalence of human papillomavirus(HPV)infections in women with uterine cervical cancer in Wenzhou.Methods Exfoliated cells samples of cervix uteri were collected from 198 patients with cervical cancer. Flow-through hybridization technique was used to detect HPV and its genotypes.The relationship of HPV infection with cervical cancer stage,histological type and differentiation degree were analyzed.The prevalence of HPV infections in patients with different cervical diseases was observed.SPSS 13.0 was used for statistical analysis.Results In 198 patients with cervical cancer,HPV infection was occunrred in 147 (74.24%), of whom 101patients were superinfected (51.01%),and 129 patients(65.15%)were infected with the high-risk HPVs,which were significantly higher than those in cervicitis and cervical dysplasia(x2 = 28.28,65.34 and 95.22,P ＜ 0.01).HPV positive rate was not correlated with clinical stages,differentiation degree of cervical cancer(x2 = 0.475 and 0.969,P＞0.05).HPV positive rates in squamous cancer and adenocarcinoma had no statistical difference (x2 =0.582,P＞0.05).The logistic regression analysis showed that HPV 16/58 infection and age over 40might increase the risk of carcinogenesis of the cervix.Conclusion sHPV infection and superinfection are popular in women with cervix cancer in Wenzhou.HPV16/58 infection and age over 40 years are the risk factors of cervical cancer.

New idea of treatment of heart failure with traditional Chinese medical / 中国中药杂志

To discuss the potential role of medicinal herbs, especially those with effect of strengthening Qi, in the treatment of chronic heart failure (CHF) via modulating myocardial substrate metabolism. The relationships among heart failure, myocardial energetic metabolism and herbal medicine were analyzed in detail through reviewing and summarizing the accumulating knowledge and recent findings on myocardial metabolism, heart failure and herbal medicine. Either energy lack or abnormal energetic metabolism is one of the main causes to the initiation and development of heart failure. Recent studies suggest that the cardiac function in the patients with CHF could be improved by inhibiting the energy production from metabolism of fatty acid and enhancing the energy production from glucose metabolism. The concept of Qi in Chinese medicine is very close to the energy in western medicine. The decoction of Chinese medicine containing herbal medicine with effect of strengthening Qi and the herbal medicine themselves and their components were evidenced to be effective in improvement of heart failure and regulation of both lipid and glucose metabolism; more importantly, all these herbal medicine contain the multi-sugar which can be metabolized into single unit of sugar which may be metabolized as a substrate by myocardium and potentially produce the cardioprotective effect. Therefore, we may find out a novel way to explain why the herbal medicine with effect of strengthening Qi can improve cardiac function in patients with CHF. In other words, regulating myocardial metabolism is one of the mechanisms underlying the cardioprotection produced by herbal medicine with effect of strengthening Qi in the treatment of heart failure.
