Objective To analyzed the left ventricular (LV) regional and global strains in coronary artery stenosis by using three-dimensional speckle tracking imaging (3D-STI) and two-dimensional speckle tracking imaging (2D-STI) for the assessment of left ventricular systolic function,and to compare the clinical values between 3D-STI and 2D-STI in the detection of coronary stenosis.Methods 39 patients with coronary artery stenosis and 32 sex-age matched controls were enrolled in this study.Coronary artery stenosis group was divided into ischemic group and non-ischemic group.Real-time three dimensional full volume and two-dimensional dynamic image of the LV were obtained and then analyzed by off-line analysis software.The parameters of 3D-STI were three-dimensional longitudinal strain (3D-LS),circumferential strain (3D-CS),radial strain (3D-RS),area strain (3D-AS),global longitudinal strain (3D-GLS),global circumferential train (3D-GCS),global radial strain (3D-GRS) and global area strain (3D-GAS).The parameters of 2D-STI were two-dimensional longitudinal strain (2D-LS),circumferential strain (2D-CS),radial strain (2D-RS),global longitudinal strain (2D-GLS),global circumferential train (2D-GCS) and global radial strain (2D-GRS).The global/regional strains derived from 3D-STI and 2D-STI in patient group and controls were analyzed for comparing their efficacy in detecting coronary artery stenosis.Results Compared with non-ischemic group,2D-LS,2D-CS,3D-LS,3D-CS and 3D-AS were lower in ischemic group (P ＜0.05).ROC curves showed the sensitivity of 2D-LS,3D-LS and 3D-AS for the diagnosis of myocardial ischemia was 60.1％,64.2 ％ and 74.0 ％,while the specificity of them was 60.0％,61.0％ and 63.1％,respectively.There was no significant difference in 2D-GCS and 2D-GRS between coronary artery stenosis group and control group (P ＞ 0.05).Compared with control group,2D-GLS,3D-GLS,3D-GCS,3D-GRS and 3D-GAS were significantly lower in coronary artery stenosis group (P ＜0.05).ROC curves showed the sensitivity of 2D-GLS,3D-GLS and 3D-GAS in the diagnosis of coronary artery stenosis was 61.3％,73.3％ and 79.3 ％,while the specificity was 65.4％,66.0 ％ and 70.8 ％,respectively.The sensitivity and specificity of 3D-GAS were the highest in these parameters.It is revealed that 2D-GLS,2D-GCS and 2D-GRS were correlated with LVEF (r1 =-0.668,P1 ＜0.001 ;r2 =-0.551,P2 ＜0.001 ;r3 =0.310,P3 ＜0.05),and 3D-GLS,3D-GCS,3D-GRS,3D-GAS were correlated with LVEF (r1 =-0.634,P1 ＜0.001 ;r2 =-0.672,P2＜0.001 ;r3 =0.698,P3＜0.001 ;r4 =-0.707,P4＜0.001).The correlate of 3D-GAS and LVEF was higher than other parameters.Conclusions 3D-STI is superior to 2D-STI in assessing regional and global left ventricular systolic function in patients with coronary artery stenosis,and 3D-GAS derived from 3D-STI is a ideal parameter of detecting significant coronary artery stenosis based on its highest sensitivity and specificity.

Originating from Treatise on Cold Damage （ZHANG Zhongjing）， Wumeiwan is a representative prescription for pungent dispersing and bitter descending， upper clearing and warm purging， and combining cold and warm， which can be used to treat abdominal pain， enduring diarrhea， and syncope caused by cold and heat in complexity and asthenia in origin and sthenia in superficiality. Owing to the remarkable clinical efficacy， it is widely applied to the treatment of various internal injuries and external-contraction diseases. In recent years， the incidence of diseases of large intestine such as ulcerative colitis， Crohn's disease， and colorectal cancer has been on the rise， threatening the quality of life and health of patients. Major headway has been made in the clinical research on the treatment of the above diseases with Wumeiwan and on the mechanisms. However， no relevant summary is available， leading to the failure of further excavation and utilization of the value of this prescription in the treatment of the above diseases in time. Therefore， this paper reviews the theoretical basis， clinical research， and mechanism research of Wumeiwan and its modified formulas in the treatment of diseases of large intestine in recent years. The literature research suggests that Wumeiwan can effectively relieve clinical symptoms and reduce recurrence rate of large intestine diseases （including ulcerative colitis， Crohn's disease， diarrhea-predominant irritable bowel syndrome， colorectal cancer， chemotherapy-induced intestinal mucositis， and postoperative colorectal adenoma） with little adverse reactions. At the moment， the mechanisms of Wumeiwan against the above diseases are anti-inflammatory response， regulating immune function， repairing intestinal mucosal barrier， anti-tumor， regulating intestinal flora， anti-oxidative damage， analgesia， and inhibiting colonic epithelial cell apoptosis， but the specific molecular mechanism should be further explored. Through literature research， this paper comprehensively analyzes the theoretical basis， clinical research， and mechanisms of Wumeiwan in the treatment of diseases of large intestine， which is expected to serve as a reference for the further research on Wumeiwan in the prevention and treatment of diseases of large intestine and the mechanisms.

OBJECTIVETo explore the influence of recombinant human growth hormones (rhGH) postburn systemic metabolism.

METHODSTwenty-four burn patients were randomly and equally divided into treatment and control groups. Same amount of rhGH (9 U/d) or isotonic saline was injected subcutaneously to respective patients during 3 approximately 17 postburn days (PBDs). Blood samples were harvested at 3, 10 and 17 PBDs for the determination of serum growth hormone, insulin-like growth factor (IGF-1), insulin-like growth factor binding protein-3 (IGFBP-3), serum proteins, plasma insulin, plasma glucagons and blood glucose, which were then compared and analyzed between two the groups.

RESULTSThe serum levels of GH, IGF-1, IGFBP-3, serum prealbumin and transferrin in rhGH treatment group were evidently higher than those in control groups at 10 and 17 PBDs (P < 0.05 approximately 0.01). But there was no obvious difference in serum albumin, plasma insulin, glucagon and blood glucose (P > 0.05).

CONCLUSIONSmall dose of rhGH could promote systemic protein synthesis with no side effects on blood glucose levels.

OBJECTIVES: To observe the efficacy and adverse reactions of the combination of endostar with chemotherapy in the treatment of advanced (IVb) and recurrent metastatic cervical cancer. METHODS: Forty-four patients with recurrent and metastatic cervical cancer, who were admitted to the Second Xiangya Hospital, Central South University from December 2016 to December 2018 were randomly divided into an experimental group and a control group (22 cases in each group). The control group was given gemcitabine plus cisplatin (GP) or docetaxel plus cisplatin (DP) treatment, the experimental group was treated with endostar on the basis of the control group. RESULTS: The objective response rate (ORR) was 42.9% in the experimental group and 22.7% in the control group. There was no significant difference between the 2 groups ( CONCLUSIONS Compared with chemotherapy alone, endostar combined with chemotherapy can prolong the median progression-free survival, with higher ORR and similar adverse reactions.
