In order to explore the significance of cardiomyocyte apoptosis in coronary heart disease (CHD), the TUNEL and transmission electron microscopic (TEM) techniques were performed. The results showed that the permillage of cardiomyocyte apoptosis in infarct area in patients of sudden death from CHD was significantly higher than that in control group (557.94? 144.10‰ VS 34.30?20.68‰, p

Objective To evaluate the effect of uterine-reserved in the pelvio floor reconstruction,and select the best surgery for patients. Methods Through the observation and follow-up for 14 cases of uterine-reserved (experimental group) and 17 cases of uterine-removed (control group), to compare the information during the surgery, postoperative recovery, and quality of life of the two groups. Results The operation time, blood loss, postoperative discharge time, antibiotics application time and hospitalization time in experimental group were significantly lower than those in control group(P ＜ 0.05). The paruria, abdominal distention in experimental group [14%(2/14), 14%(2/14)] were significantly lower than those in control group [53% (9/17), 24% (4/17)] (P ＜ 0.05), and sexual satisfaction was significantly higher in experimental group than that in control group [71% (10/14) vs. 47% (8/17)] (P ＜ 0.05). There were no significant difference in pelvic pain, constipation of the two groups (P＞ 0.05). The POP-Q scores were normal after the operation both the two groups, each group beforeand after surgery compared the POP-Q score, were statistically significant (P ＜ 0.05). Conclusions Uterine-r eserved in the pelvic floor reconstruction can maintain the structural stability of the pelvic floor, and has the advantage of shorter operation time, less bleeding, more rapid recovery. Recent results are similar with hysterectomy, can reduce the risk of perioperative period to the elderly women.

Objective To study the level of cyclooxygenase-2 (COX-2) and platelet-activating factor acetyl-hydrolase(PAF-AH) and high sensitive C reactive protein(hsCRP) on peripheral blood mononuclear cells in Acute Coronary Syndrome(ACS) patients and the effect of atorvastatin on them and the clinical significance. Methods To measure and compare the content of COX-2,PAF-AH and hsCRP in normal control group and ACS group(before and after treatment). Result The content of COX-2,PAF-AH and hsCRP are significantly different between normal con-trol group and ACS group (before treatment) (P < 0.05), and between ACS group (before treatment) and ACS group (after treatment) too(P < 0.05). Conclusions The inflammatory cytokines COX-2,PAF-AH and haCRP have sig-nificant correlation with the occurance of ACS. Atorvastatin can decrease COX-2 and hsCRP level, and can increase PAF-AH level. So atorvastatin takes an important role in lessening inflamatory reaction level in ACS patients.

Objective To investigate the dynamic expression of SOCS-3, TNF-α in live and spleen of mice induced by AOPP, and to discuss the mechanism of MODS induced by AOPP, so that to give some intervention method over MODS in the future. Method Thirty-six adult BALB/c mice were divided into 3 groups randomly: AOPP group (n=12). Water normal group (n=12) and normal group (n=12). After post poison 2 hours, 6 hours, 12 hours and 24 hours,the fiver and the spleen tissue were taken out. The expression of SOCS-3 and TNF-α were detected by RT-PCR. And data were analyzed with ANOVA. Results After AOPP of 2,6,12,24 hours, the mRNA expression of SOCS-3 increased obviously in the liver and spleen compared with the normal group (P<0.05), it reached peak at the 24th hour in liver,and reached peak at the 12th hour in spleen, then descended at 24th hour (P<0.05). The mRNA expression of TNF-α increased obviously in the liver and spleen than normal group (P<0.05), and reached peak at the 12th hour,then descended at 24th hour (P<0.05), the electro-phoresis image of RNA was 5 s 15 s and 30 s,RT-PCR amplification of β-actin showed,the expression of SOCS-3, reached peak at the 24th hour in liver and it reached peak at the 12th hour in spleen, then descended at 24th hour (P<0.05), TNF-α reached peak at 12th hour in the liver and spleen, then descended at 24th hour. By statistic analysis, positive correlation was indicated among SOCS-3 and TNF-α mRNA expression in liver (y=0.089+0.758x, r=0.939, F=252. 168, P<0.01) positive correlation was indicated among socs-3 and TNF-α mRNA expression in spleen (y=0.057+0.361x,r=0.953,F=336.122, P<0.01). Conclusions At different point of time after Aopp,the mRNA expression of socs-3 and TNF-α showe the same trend in liver and spleen,the levels of SOCS-3, TNF-α all increase significenfly.

Objective To evaluate the significance and role of ultrasound parameters in the female stress urinary incontinence (SUI). Methods The changes of the distance of bladder neck mobility,posterior urethra-vesical angle,urethral angle and residual urine volume before and after the operation of transobturator tension-free vaginal tape surgery (TVT-O) for 46 cases of female SUI (experimental group ) by ultrasound were studied,and compared with 43 normal women (control group). Results The experimental group before the operation had the greater distance of bladder neck mobility and posterior urethra-vesical angle [(14.46 ± 1.28) mm, (124.87 ±2.95)°] than the control group [(7.47 ±0.55) mm, (107.83 ±3.24)°] (P ＜ 0.01 ), but the urethral angle [( 23.61 ± 2.28 )°] was smaller than the control group [(36.24 ±2.23 )°] (P ＜ 0.01 ). There was no significant difference in the distance of bladder neck mobility, posterior urethra-vesical angle, urethral angle and residual urine volume between the experimental group after the operation and the control group (P ＞ 0.05 ). The experimental group before the operation had the greater distance of bladder neck mobility and posterior urethra-vesieal angle than those after the operation [(7.84±0.76) mm, (108.74±3.63)°] (P ＜0.01), the urethral angle was smaller than that after the operation [(34.39 ± 3.46)°] (P ＜ 0.01 ), but the residual urine volume had no significant difference (P ＞ 0.05 ).Conclusions After the operation, there are some changes in the distance of bladder neck mobility, posterior urethra-vesical angle and urethral angle for the patients with female SUI,and these parameters can be restored the normal state,and have the relatively stable effect. The residual urine volume dosen't increase after the operation. Ultrasound has the advantage in objectively assessing the severity and recovery status after the operation exclusion of mental and psychological factors.

Objective To investigate the change of the content of suppressor of cytokine signaling (SOCS-1) in the liver of septic mice and its working mechanism.Methods Adopted Cecalligation and puncture (CLP) to create models of sepsis and divided randomly adult male BALB/c mice into 8 groups,including normal controlled group,sham-operated group,and the killed groups 2 hours,6 hours,12 hours,24 hours and 48 hours after operation.After extracting the RNA and protein from the liver tissue of the mouse groups,reverse transcription polymerase chain reaction (RT-PCR) was adopted to determine the relative content of SOCS-1 mRNA in the tissue,Western blot was adopted to determine the relative content of protein and the SPSS statistics software was adopted to calculate the correlation.Then observed the pathological change of liver tissues,and detected SOCS-1 protein expression by immunohistochemistry.Results After CLP suergery,the expression of SOCS-1 on gene degree in the liver and the expression of SOCS1 on protein degree in the liver increased rapidly at the 6th hour ( P ＜ 0.05 ),with the former reaching peak ( P ＜ 0.05 ) at the 24th hour and the latter remaining high all the time.There were pathological changes such as fatty degeneration and necrosis in the septic liver tissue,hepatic SOCS-1 protein expression could be detected by immunohistochemistry.Conclusions CLP induced sepsis could lead to the increase of the expression of SOCS1 in the liver.

Objective To investigate the value of serum cholinesterase (S-ChE) levels in judgment of severity and prognosis in patients with severe pneumonia. Methods The clinical data of patients with severe pneumonia, who were admitted to the Department of Internal Medicine in the First Affiliated Hospital of Sun Yat-sen University, or the Department of Neurology in the Third People's Hospital of Foshan from May 2011 to May 2015, whose hospital time was longer than 24 hours, were retrospectively analyzed. They were divided into survival group and death group according to the final outcome. Lab data, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score, multiple organ dysfunction syndrome (MODS) score, the improved pneumonia score of British Thoracic Society (confusion, uremia, respiratory, blood pressure, age 65 years, CURB-65), and S-ChE levels of all patients were collected after they were hospitalized into the intensive care unit (ICU) within 24 hours. Independent risk factors for prognosis were analyzed by binary logistic regression analysis, and receiver operating characteristic curve (ROC) was plotted. Best truncation point analysis was used to compare their estimated value for prognosis of patients with severe pneumonia. Results Eighty-six patients with severe pneumonia were studied. Among them 46 patients survived, and 40 patients died. By the single factor analysis, the following lab data in the death group were found significantly lower than those in the survival group: S-ChE levels (kU/L: 2.748±0.826 vs. 4.489±1.360, t' = 7.274, P = 0.000), arterial partial pressure of oxygen [PaO2 (mmHg, 1 mmHg = 0.133 kPa): 52.55±18.29 vs. 60.83±16.65, t = 2.196, P = 0.031], oxygenation index (mmHg: 114.20±48.01 vs. 167.10±69.68, t' = 4.229, P = 0.000), and carbon dioxide combining power [CO2-CP (mmol/L): 22.85±5.44 vs. 26.00±7.63, t' = 2.225, P = 0.029]. The following clinical data were significantly higher in the death group than those in the survival group, namely body temperature (℃: 38.67±1.18 vs. 37.74±1.18, t = -3.627, P = 0.000), pulse (bpm: 130.65±15.72 vs. 107.26±19.61, t' = -6.133, P = 0.000), the ratio of concomitant chronic lung disease [45.0% (18/40) vs. 13.0% (6/46), χ2 = 10.860, P = 0.001], fraction of inspired oxygen [FiO2: 0.495 (0.410, 0.600) vs. 0.380 (0.290, 0.500), Z = -3.265, P = 0.001], APACHE Ⅱ score (25.80±5.07 vs. 16.39±5.12, t =-8.540, P = 0.000), CURB-65 score [3 (3, 4) vs. 2 (1, 2), Z = -5.562, P = 0.000], MODS score (8.15±2.49 vs. 4.35±2.01, t = -7.832, P = 0.000), international normalized ratio [INR: 1.22 (1.08, 1.31) vs. 1.07 (1.00, 1.10), Z = -4.231, P = 0.000], and activated partial thromboplastin time [APTT (s): 33.80 (32.13, 38.75) vs. 28.50 (25.70, 36.00), Z = -3.482, P = 0.000]. Binary logistic regression analysis showed that, S-ChE levels, APACHE Ⅱ score and MODS score were found to be the independent risk factors for prognosis in the patients with severe pneumonia, respectively [S-ChE: odds ratio (OR) = 0.084, 95% confidence interval (95%CI) = 0.017-0.424, P = 0.003; APACHE Ⅱ score: OR = 1.675, 95%CI = 1.098-2.556, P = 0.017; MODS score: OR = 2.189, 95%CI = 1.262-3.800, P = 0.005]. The area under ROC (AUC) for S-ChE levels, APACHE Ⅱ score and MODS score were 0.874±0.036, 0.889±0.033 and 0.884±0.035, respectively (all P > 0.05 as compared between any two means). At the best truncation points of S-ChE levels, APACHE Ⅱ score and MODS score were 3.372 kU/L, 19.5 score, and 6.5 score respectively. The sensitivity, specificity, positive predictive value and negative predictive value in predicting death risk in patients with severe pneumonia were (80.0%, 78.0%, 76.19% and 81.82%), (95.0%, 70.0%, 73.08% and 94.12%) and (70.0%, 91.0%, 87.50%, 77.78%), respectively. If S-ChE levels was combined with APACHE Ⅱ score or combined with MODS score, the sensitivity, specificity, positive predictive value and negative predictive value [S-ChE levels combined APACHE Ⅱ score: 100%, 92.0%, 93.75% and 100%; S-ChE levels combined MODS score: all 100%] were higher than single power of S-ChE levels, APACHE Ⅱ score or MODS score. Conclusions S-ChE levels can be considered as an effective and practical index to estimate the severity and prognosis in patients with severe pneumonia. The combined application of S-ChE levels and APACHE Ⅱ score or MODS score can obviously improve the prognostic power in patients with severe pneumonia.
