Objective To explore the associations between fasting serum lipids and high-sensitivity C-reactive protein ( hsCRP).Methods Serum triglyceride ( TG),high-density lipoprotein cholesterol (HDL-C) and hsCRP were measured in residents of Chengdu,China.Subjects with potential factors which might influence lipids and hsCRP were excluded,580 subjects [ mean age ( 62.3 ± 6.6 ) years ; male:58.7％ ] were finally recruited by random sampling methods.Results There was a weak positive relationship between TG and hsCRP ( r =0.108,P =0.01 ) and a weak negative relationship between HDLC and hsCRP (r =- 0.197,P ＜ 0.001 ),this was also true in the sub-group with BMI ＜ 24 kg/m2 ( r =0.236,-0.140 respectively,all P ＜0.001 ).In subjects with BMI ＜24 kg/m2,the hsCRP concentration was significantly higher in subjects with higher TG or lower HDL-C ( all P ＜ 0.05 ).hsCRP increased in proportion with the degree of dyslipidemia.After adjusting for gender,age,TC,LDL-C,fasting blood glucose,systolic blood pressure,diastolic blood pressure,history of hypertension and diabetes,smoking and alcohol drinking,logistic regression analysis showed that the odds ratio for increased hsCRP was 1.970 in subjects with either increased TG or lower HDL-C (P =0.105) and 9.098 in subjects with both higher TG or lower HDL-C levels (P =0.031 ).However,the observed relationship between TG,HDL-C and hsCRP in subjects with BMI ＜ 24 kg/m2 could not be observed in subjects with subjects with BMI ＞ 24 kg/m2despite significant more cardiovascular risk factors in these subjects.Conclusions A weak positive correlation between TG and hsCRP as well as a weak negative correlation between HDL-C and hsCRP was evidenced in the whole cohort suggesting dyslipidemia might be related to enhanced inflammatory status.However,this relationship is not observed in subjects with BMI ＞ 24 kg/m2 despite existence of more cardiovascular risk factors in these subjects.

OBJECTIVETo evaluate the clinical effectiveness of transurethral seminal vesiculoscopy (TUSV) combined with finasteride in the treatment of recurrent hemospermia.

METHODSThis study included 32 patients with recurrent hematospermia, with the disease course of 3 months to 4 years. After administration of finasteride at 5 mg/d for 2 weeks, the patients underwent TUSV for both exploration of the causes and treatment, followed by medication with finasteride at the same dose for another 2 weeks. Postoperative follow-up was conducted for observation of the outcomes and complications.

RESULTSTUSV was successfully accomplished in all the 32 cases, which revealed 16 cases of seminal vesiculitis, 10 seminal calculi, 1 seminal vesicle cyst, 2 seminal vesicle polyps, and 3 seminal vesicle abscess. The operative time was 20 to 51 (31.0 +/- 5.2) minutes. Postoperative complications included 1 case of acute epididymitis and 3 cases of breast discomfort within the first 4 weeks. No incontinence, urethral stricture, rectal injury, retrograde ejaculation, and sexual dysfunction occurred postoperatively. All the patients but 1 were followed up for 6 months to 2 years. Twenty-nine of the cases were cured, and 2 experienced recurrence.

CONCLUSIONTransurethral seminal vesiculoscopy combined with finasteride is safe and effective for the treatment of recurrent hemospermia.

Objective To explore the application of nurse-nurse independence shift mode in the clinical nursing morning-evening shift so as to promote the continuous improvement of nursing quality.Methods Based on the conventional shifting mode and bedside shifting mode,an independent shifting mode between nurses and nurses was adopted that introduced the condition of each patient in the wards in detail.The nurses' knowledge of each patients' condition,the patients' satisfaction,the approbation of medical staff,and the shift delivery time were observed and compared before and after implementation.Results After the nurse-nurse independence shift mode applied,the score of nurses' knowledge of each patients' condition and patients' satisfaction were ( 8.65 ±0.59 ),( 96.15 ± 3.3 1 ),higher than before that ( 6.30 ± 1.30 ),( 90.40 ± 5.82 ),and the differences were statistically significant (t =- 7.19,- 5.20,respectively ; P ＜ 0.01 ).And doctors' and nurses' approbation on the new shift mode was 91.67％ and 90.00％,respeetively,and significantly higher than 41.67 ％ and 45.00％that of before,the differences were statistically significant ( x2 =6.75,9.23,respectively ; P ＜ 0.05 ).while there was no significant difference was detected in the shift delivery time after the new mode was applied( P ＞0.05 ).Conclusions The nurse-nurse independent shift mode combines with the mixed shift mode can improve the nursing quality and worth promoting in clinic.

The prenatal ethanol exposure induced the alterations of dendritic spine and synapse in visual cortex and their long-term effect would be investigated in mice from P0 to P30. Pregnant mice were intubated ethanol daily from E5 through the pup's birth to establish mode of prenatal alcohol abuse. The dendritic spines of pyramidal cells in visual cortex of pups were labeled with DiI diolistic assay, and the synaptic ultrastructure was observed under transmission electron microscope. Prenatal alcohol exposure was associated with a significant decrease in the number of dendritic spines of pyramidal neurons in the visual cortex and an increase in their mean length; ultrastructural changes were also observed, with decreased numbers of synaptic vesicles, narrowing of the synaptic cleft and thickening of the postsynaptic density compared to controls. Prenatal alcohol exposure is associated with long-term changes in dendritic spines and synaptic ultrastructure. The changes were dose-dependent with long term effect even at postnatal 30.

In order to explore the underlying mechanism of high effects and low toxicity of trichostatin A (TSA), the effect of TSA on growth inhibition, histone acetylation level and apoptosis in HL-60 cells and normal human peripheral blood mononuclear cells (NPBMNC) were examined using MTT method, immunocytochemistry technology, and Annexin-V-FITC/PI double staining flow cytometry. The results showed that TSA inhibited growth of HL-60 in time- and dose-dependent manners, and the IC(50) of 36 hours was 100 ng/ml. The apoptosis induction effect of TSA in HL-60 cells was also time- and dose-dependent. Besides, the dose of TSA showing significant apoptotic cytotoxicity in HL-60 cells did not demonstrate apparent apoptosis induction in NPBMNC within definite dose and time range. The histone acetylation level in HL-60 cells and NPBMNC both showed remarkable increase (P < 0.05) after incubated with 100 ng/ml TSA for 4 hours without statistical difference between them is detected (P > 0.05). It is concluded that TSA shows effects of definite and significant growth inhibition and apoptosis induction on HL-60 cells in time- and dose-dependent manners. TSA is able to selectively induce apoptosis in HL-60 cells with low toxicity in NPBMNC at the same time. The mechanism of this selectivity can not be ascribed to the differential regulation of histone acetylation level between HL-60 cells and NPBMNC.

OBJECTIVETo study the application of retroperitoneal laparoscopic partial nephrectomy in renal carcinoma patients with intermediate risk PADUA score.

METHODSFrom April 2005 to June 2011, 79 cases (48 males and 31 females) of intermediate risk PADUA score (range from 8 to 9 score) renal cell carcinoma were retrospectively analyzed. Mean age was (54 ± 9) years, mean tumor size was (2.8 ± 0.8) cm in diameter, with 37 cases on the left side and 42 cases on the right side. Tumor located anteriorly in 35 cases, and 44 cases were located posteriorly. Preoperative imaging examinations showed tumor invasion of the collecting system was dislocated or infiltrated by tumor invasion were in 13 cases, renal sinus were involved in 5 cases, tumor located near the renal hilum were in 10 cases. All of the 79 patients received retroperitoneal laparoscopic partial nephrectomy.

RESULTSThe 79 cases were operated successfully without conversion to open surgery, no severe perioperative complications. The mean operation time was (105 ± 24) minutes, and the median of operation time was 115 minutes (range from 80 - 180 minutes), and mean warm ischemia time (WIT) was (20 ± 5) minutes, and mean blood loss was (24 ± 8) ml; mean postoperative hospital stay was (5.2 ± 1.5) days. Postoperative urinary leakage in 3 cases, symptoms disappeared one week after indwelling catheterization and ureteral catheter. Serum creatinine transient increased in 7 cases after surgery, and fell to normal range within 6 weeks. In a mean follow up for (34 ± 12) months (range from 10 to 84 months), estimated glomerular filtration rate (eGFR) 6 months after operation was no statistical significance compared with preoperation in 77 cases, another 2 patients' eGFR decreased by 30% and 35%. Postoperative renal function remained in CKD3 period and CKD2 period were in 2 cases respectively, none of these cases were treated with hemodialysis, and the remaining patients with normal renal function after surgery, no tumor recurrence and metastasis during follow-up in all cases.

CONCLUSIONSTreatment of retroperitoneal laparoscopic partial nephrectomy in renal carcinoma patients with intermediate risk PADUA score is safe and effective, but its long-term effects still need to study with large samples compare and long-term follow-up.

OBJECTIVETo assess the diagnostic value of magnetic resonance imaging (MRI) in the follow-up of patients with hepatocellular carcinomas treated with radiofrequency ablation (RFA) and to compare it with that of computed tomography (CT).

METHODSFrom December 2009 to September 2011, 40 patients (47 hepatocellular carcinomas) were treated with RFA after transcatheter arterial chemoembolization and underwent MRI and CT for follow-up. RFA margins were assessed on a five-point scale with receiver operating characteristic curve analysis. Sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were evaluated.

RESULTSThe interobserver agreement rate for MRI was significantly higher (Kappa=0.935) than for CT (Kappa=0.714; P < 0.05). The scores of 1 and 5 points for MRI, which confirms the presence or absence of residual tumor, accounted for 89.4% (84/94), while for CT accounting for only 31.9% (30/94). The area under the receiver operating characteristic curve of MRI was significantly higher than that of CT (P < 0.05), as were the sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of detection rate (mean, 100%, 96.4%, 76.9%, 100%, and 96.8% for MRI, respectively, vs. 30.0%, 57.1%, 10.3%, 87.7%, and 63.8% for CT).

CONCLUSIONMRI is superior to CT in assessing the RFA margins in terms of the diagnostic accuracy and detection rate .

Objective To prospectively investigate the diagnostic accuracy for coronary artery stenosis of prospectively electrocardiogram-triggered spiral acquisition mode (high pitch mode) dual-source computed tomography coronary angiography (CTCA) in patients with relatively higher heart rates (HR) compared with catheter coronary angiography (CCA). Methods Forty-seven consecutive patients with relatively higher HR (>65 and <100 bpm) (20 male, 27 female; age 55±10 years) who both underwent dual-source CTCA and CCA were prospectively included in this study. All patients were performed CTCA using high pitch mode setting at 20%-30% of the R-R interval for the image acquisition. All coronary segments were evaluated by two blinded and independent observers with regard to image quality on a three-point scale (1: excellent to 3: non-diagnostic) and for the presence of significant coronary stenoses (defined as diameter narrowing exceeding 50%). Considered CCA as the standard of reference, the sensitivity, specificity, positive predictive value and negative predictive value were calculated. Radiation dose values were calculated using the dose-length product. Results Image quality was rated as being score 1 in 92.4% of segments, score 2 in 6.1% of segmentsand score 3 in 1.5% of segments. The average image quality score per segment was 1.064±0.306. The HR variability of patients with image score 1, 2 and 3 were 2.29±1.06 bpm, 5.17±1.37 bpm, 8.88±1.53 bpm, respectively. The average HR variability of patients with different image scores were significantly different (F=170.402, P=0.001). The sensitivity, specificity, positive and negative predictive values were 92.6%, 97.0%, 87.6%, 98.3%, respectively, per segment and 90.0%, 95.2%, 85.3%, 96.9%, respectively, per vessel and 100%, 63.6%, 90.0%, 100%, respectively, per patient. The effective radiation dose was on average 0.86±0.16 mSv. Conclusion In patients with HR more than 65 bpm and below 100 bpm without cardiac arrhythmia, the prospectively electrocardiogram-gated high-pitch spiral acquisition mode with image acquired timing set at 20%-30% of the R-R interval provides a high diagnostic accuracy for the assessment of coronary stenoses combined with a 1.5% of non-diagnostic coronary segments and a radiation dose below 1 mSv.

Objective To study the anti-reflux effect of conical gastric stump embedding in radical resection of esophageal cancer.Methods A total of 60 patients who planned to undergo radical resection of esophageal cancer in our hospital from June 2020 to June 2022 were selected as the study objects,and the patients were divided into the observation group and the control group by random number table method,with 30 cases in each group.Patients in both groups underwent laparoscopic radical resection of esophageal cancer and esophagogastric end-to-side mechanical anastomosis.The observation group adopted the conical gastric stump embedding technique after esophagogastric end-to-side mechanical anastomosis.The perioperative related indexes,postoperative complications and gastroesophageal reflux of patients in the two groups were compared.The postoperative anti-reflux effect was evaluated by reflux disease questionnaire(RDQ)score and 24-hour intraesophageal pH monitoring.Results The operation time and digestive tract reconstruction time of patients in the observation group were longer than those in the control group(P<0.05),while there was no statistically significant difference in the amount of intraoperative bleeding,the number of lymph node dissection,the first exhaust time,or the postoperative hospital stay of patients between the two groups(P>0.05).There was no statistically significant difference in the overall incidence of postoperative complications between the two groups(P>0.05).The severity of postoperative gastroesophageal reflux of patients in the observation group was lighter than that in the control group,and the difference was statistically significant(P<0.05).The RDQ score,24-hour reflux frequency,>5 minutes reflux frequency,pH<4 time,and longest reflux time of patients in the observation group was significantly lower/less/shorter than those in the control group(P<0.05).Conclusion The conical gastric stump embedding technique is safe and feasible in the radical resection of esophageal cancer.Although the operation time and digestive tract reconstruction time are slightly prolonged,it does not increase the perioperative risks,which can significantly reduce the occurrence and severity of postoperative gastroesophageal reflux of patients,and achieve a good anti-reflux effect.
