Objective To compare the treatment outcome of underwent surgery plus radiotherapy and radiotherapy/chemoradiotherapy plus salvage surgery for stage Ⅲ/Ⅳ laryngeal carcinoma,to investigate an optimized treatment for the patients of stage Ⅲ/Ⅳ laryngeal carcinoma.Methods Clinical data from 103 patients with stage Ⅲ (39 cases) or stage Ⅳ (64 cases) laryngeal carcinoma were retrospectively analyzed.The patients were divided into surgery plus radiotherapy group (S±R,46 cases) and radiotherapy/chemoradiotherapy plus salvage surgery group (R±S,57 cases).Overall survival,relapse free survival,and laryngeal preservation rate were used to compare the treatment outcome between two groups.Multivariate regression models were used to analyze the independent factors for survival and laryngeal preservation rate.Results Survival rate was higher in S±R group than in R±S group [2 year overall survival/relapse free survival 74.7 ％ (34/46) / 72.4 ％ (33/46) vs 46.4 ％ (26/57) / 40.9 ％ (23/57),P ＜ 0.05].Laryngeal preservation rate was higher in R±S group than in S±R group [93.0 ％ (15/46) vs 32.6 ％ (53/57),P ＜ 0.05].Multivariate analysis demonstrated that treatment modality and T stage were independent factors for long-term survival,while treatment modality was the only an independent factor for laryngeal preservation rate.Conclusions Surgery plus radiotherapy result in better survival and lower laryngeal preservation rate than radiotherapy/chemoradiotherapy plus salvage surgery in treatment of stage Ⅲ/Ⅳ laryngeal carcinoma.Surgery plus radiotherapy should be the first choice for treatment of locally advanced laryngeal carcinoma.Improvement of the quality of life could be achieved by laryngeal preservation surgery and phonation reconstruction procedures.

Objective:To evaluate the relationship between red blood cell distribution width (RDW) and metabolic syndrome (MS) in patients with impaired glucose tolerance (IGT).Methods:A total of 415 patients with abnormal glucose tolerance were screened by oral glucose tolerance test in Changsha Traditional Chinese Medicine Hospital (Changsha Eighth Hospital) from October 2015 to September 2019. General data were collected and blood routine and biochemical indexes were detected. There were 193 cases in the observation group and 222 cases in the control group. The RDW and other clinical indicators were compared between the two groups, the correlation between RDW and other indicators was analyzed, and the risk factors of metabolic syndrome were analyzed.Results:⑴ The RDW, systolic blood pressure (SBP), diastolic blood pressure (DBP), height (Ht), weight (Wt), waist circumferenc (Wc), triglyceride (TG), cholesterol (CHOL), low density lipoprotein (LDL), creatinine (Cr), uric acid (UA), alanine aminotransferase (ALT), high sensitive C-reactive protein (hs-CRP), body mass index (BMI) of the observation group were significantly higher than those of the control group, while the high density lipoprotein (HDL) was significantly lower than that of the control group, with statistically significant difference ( P<0.05); ⑵ correlation analysis showed that RDW was positively correlated with SBP, DBP, Ht, Wt, Wc, TG, CHOL, Cr, UA, ALT, hs-CRP, BMI, and negatively correlated with HDL ( P<0.05); ⑶ binary logistic regression analysis showed that RDW, Wt, Wc, CHOL, HDL, LDL and hs-CRP were independent risk factors for MS in patients with impaired glucose tolerance. Conclusions:The increase of RDW is a predictor of metabolic syndrome in people with abnormal glucose tolerance, which may provide some reference value for the prevention and treatment of metabolic syndrome.

Adult rats chronic unpredictable stress model of depression (CUS) was adopted to elucidate the antidepressant pharmacological activity and related neurogenesis protective effect of the total flavonoids extract (licorice flavonoids, LF) from the Glycyrrhiza uralensis Fisch. cultivated locally in Ningxia. The rats were exposed to 9 kinds of unpredictable sequence of stressors and were given flavonoids (300 mg x kg(-1), 100 mg x kg(-1) and 30 mg x kg(-1)) for 28 days. The antidepressant effect was elucidated by open field test, forced swimming test and tail suspension test. The level of serum corticosterone was detected by radioimmunoassay. 5'-Bromo-2'-deoxyuridine (BrdU) labeling experiments was employed to study the neurogenesis protective activities. The flavonoids can increase the sum of line crosses and number of rears, and decrease the number of fecal boli produced in the open field test of the CUS rats. Also the flavonoids can decrease the immobility time in forced swim test as well as in the tail suspension test. In addition, the flavonoids (300 mg x kg(-1)) can decrease the serum corticosterone level of the CUS rats, and increase the number of the new born BrdU positive progenitor cells at the subgranular zone (SGZ) of dentate gyrus (DG) region in hippocampus. The results demonstrated that the total flavonoids extract from the cultivated Glycyrrhiza uralensis Fisch. could produce the anti-depressive effect on chronic unpredictable stress of depression model rats and its mechanism may be associated with its neurogenesis protective effect.

Objective To explore the relationship between optical coherence tomography (OCT) characteristics and peripheral blood leukocyte count in patients with acute myocardial infarction(AMI). Methods A total of 33 patients with AMI hospitalized in Fuwai Hospital for primary percutaneous coronary intervention were consecutively enrolled,and underwent intracoronary OCT procedures after manual aspiration of coronary thrombus. Demographic data, risk factors, procedural and OCT data, past medical history and perioperative laboratory findings were collected in all patients. Results The lymphocyte count,monocyte count and basophil count were significantly higher in the patients with fibrous cap thickness ≥ 65 μm than in those patients with fibrous cap thickness ≤ 65 μm. Patients presenting with cholesterol crystallization had lower eosinophil count than those patients with crystallization-free [(0.04±0.06)×109/L vs.(0.10±0.09) ×109/L,P =0.028]. In addition,the former had significantly higher to neutrophil lymphocyte ratio than the latter [(8.35±6.13)vs.(4.97±2.01), P =0.020]. Higher monocyte count was found in the patients with calcified plaque (P <0.05). Platelet to lymphocyte ratio was significantly increased in the patients with macrophage infiltration [(165.72±85.93)vs.(113.47±19.13),P <0.05]. The leukocyte count,neutrophil count and monocyte count showed the treat of elevation as the number of OCT characteristics increased,but only the elevation of monocyte count had statistical significant level (P = 0.014). Conclusions Peripheral blood leukocyte count seems to be associated with OCT characteristics of plaque rupture in patients with acute myocardial infarction,suggesting the potential role of inflammation in plaque rupture.

Objective To investigate the predictive value of metabolic syndrome in patients with acute coronary syndrome (ACS) after percutaneous coronary intervention (PCI).Methods A total of 660 patients with ACS admited to cardiovascular department,first affiliated hospital of zhengzhou university were enrolled in this study from January 2009 to June 2010.The enrollment criteria were:the stenosis degree were above 75％ in at least one coronary artery by coronary angiography and successful PCI procedure.Exculsion criteria were:liver and renal insufficiency,malignancies and valvular heart diseases.The relevant clinical data and labtory examination were recorded after admission. The patients were followed up by outpatients interview or telephone from March to June 2011 and adverse cardiovascular events were recorded.The patients were divided into MS and non-MS groups,and basic clinical data were compared between two groups.The proportion difference between two groups were tested by chi square. Multivariate logistic regression was established to analyze the factors related to progonosis.The survival ratio was estimated using the Kaplan-Meier method.Statistical significance was established at a P value of less than 0.05.Results ①A total of 606 (91.7％) patients successfully accepted follow-up.Mean follow-up time were ( 14.3 ±1.7 ) months.95 patients experienced adverse cardiovascular events ( 15.7％ ).②There were 393 patients (64.96％ ) satisfied the definition of metabolic syndrome.The patients in MS group were with higher BMI,SBP,DBP,blood glucose and disordered lipid (all P ＜ 0.05 ),with less fale patients (P =0.016),less current somking (P =0.008 ) and with higher platelet (P =0.037 ). The incidence of adverse cardiovascular events in two groups were 17.81％ and 11.79％ ( P ＞ 0.05 ). ③ Multivarite logistic regression revealed that the predictors of adverse cardiovascular events were age [ OR =2.628,95％ confidence interval (CI) 1.395 ～ 4.954,P =0.003 ],New York Heart Association (NYHA) ≥ 3 grade ( OR =2.310,95％ CI 1.095 ～4.870,P =0.028) and left ventricular ejection fraction (LVEF) ( OR =4.328,95％ CI 1.955 ～9.580,P ＜ 0.001 ).However,MS was not related with prognosis ( OR =1.170,95％ CI 0.583 ～ 2.345,P =0.659 ).④The cumulative survival rates of no adverse cardiovascular events in the two groups were no significant difference ( P ＞ 0.05 ).Conclusions MS is a risk factor with coronary heart disease.Howerer,it has no relationship with adverse cardiovascular events in patients with ACS after PCI.

In contrast , HSCT-PTLD has an earlier onset and a higher incidence of EBV infectious .And application of ATG and high ECOG scores are poor prognosis factors of PTLD .

In the paper, it is introduced professor's recognition on the pathogenesis and professor's experience in the treatment of the motor impairment of the trunk after stroke. Professorbelieves that the motor impairment of the trunk after stroke is the essential factor affecting the rehabilitation in stroke. The motor impairment of the trunk after stroke results from brain marrow damage and spiritual impairment. Hence, regaining the consciousness and promoting the circulation of the governor vessel are the basic principles of the treatment, named regulating the mind and controlling, benefitingand warming, tonifying the kidney and filling up the essence, and promoting the circulation of the governor vessel. Those four therapeutic methods are equally important. Acupuncture, moxibusiton and herbal medicine are applied in combination in the treatment. Additionally, the psychotherapy and rehabilitation are the accessory therapies.

Objective: To investigate the clinical features and change trend of patients with acute coronary syndrome(ACS) undergoing emergent percutaneous coronary intervention(PCI). Methods: In this retrospective study, we retrieved all medical records of 4 907 ACS patients who underwent emergent PCI in Fuwai hospital from January 1,2010 to December 31,2016. We analyzed the clinical features and change trend in these patients. According to clinical diagnosis, patients were grouped as ST-elevated myocardial infarction(STEMI) group (3 719 cases) and NSTE-ACS group (patients with non-STEMI and unstable angina, 1 188 cases). Results: The ACS patients were aged (59.5±11.8) years old. There were 3 772 males and 1 135 females. The annual number of ACS patients underwent emergent PCI increased from 412 patients in 2010 to 1 067 patients in 2016. The number of NSTE-ACS patients increased from 11.4% (47/412) in 2010 to 26.5% (283/1 067) in 2016. Compared with STEMI group, patients in NSTE-ACS group were significantly older ((61.2±10.9) years old vs. (58.9±12.1) years old,P<0.01).The percent of female patients (30.1% (358/1 188) vs. 20.9% (777/3 719), P < 0.01), history of hypertension (69.1% (821/1 188) vs. 60.4% (2 248/3 719,P <0.01), previous PCI (25.8% (307/1 188) vs. 12.4% (461/3 719), P <0.01), and previous coronary artery bypass grafting (3.0% (36/1 188) vs. 1.0% (37/3 719), P <0.01) were all significantly higher in NSTE-ACS group than in STEMI group. On the other hand, NSTE-ACS patients presented less chronic renal failure (2.9% (35/1 188) vs. 4.3% (173/3 719), P <0.05) and hepatic dysfunction (8.5% (101/1 188) vs. 13.3% (495/3 719), P<0.01) as compared to ACS patients. In coronary angiography, NSTE-ACS patients had a higher prevalence of left-main disease (14.0% (166/1 188) vs. 7.8% (291/3 719), P<0.012 5) and triple vessel disease (47.8% (568/1 188) vs. 43.5% (1 619/3 719), P<0.012 5). There were no differences in prevalence of diabetes mellitus (31.9% (1 187/3 719) vs. 34.8% (414/1 188),P>0.05) and acute renal failure (0.1% (38/3 719) vs. 0.6% (7/1 188),P>0.05) between STEMI group and NSTE-ACS group. Conclusions This single center retrospective analysis reveals that there is an increasing trend of NSTE-ACS patients from 2010 to 2016. Furthermore, there are more high-risk clinical characteristics in NSTE-ACS patients than in STEMI patients.
