Objective Arrhythmias are one of the main causes of postoperative morbidity after thoracic surgery.The aim of this study was to evaluate whether video-assisted thoracoscopic surgery decreases the risk of postoperative arrhythmias compared with traditional open lung lobectomy.Methods 138 consecutive patients were enrolled from January 2011 to February 2012,after five age and risk factors matched,68 patients undergoing video-assisted thoracic surgery and 70 patients undergoing traditional open lung lobectomy were eligible for analysis.The rhythm was documented preoperatively and postoperatively with standard electrocardiogram (ECG) recording and ECG monitoring.All patients followed 3 months after hospital admission.Results There was a 17.6％ incidence (12/68) of postoperative new-onset arrhythmias undergoing video-assisted thoracic surgery and 18.6％ of patients (13/70) undergoing thoracotomy,but the difference was not statistically significant.In both groups,atrial fibrillation was the most common arrhythmia (60％).There was no significant difference in the other morbidity (P ＞0.05) and mortality rate(P =0.57,1.5％ vs 2.9％) between the two groups.Conclusion New-onset arrhythmias,most frequently atrial fibrillation,are common after lung lobectomy.Regardless of surgical approach,postoperative arrhythmias after lobectomy occurred with equal frequency.New insights in the pathophysiology of postoperative thoracic arrhythmias and advances in prevention and therapy are need future study.

Objective To examine whether neonate′s cord blood T-lymphocytes is related to infant temperament.Methods Twenty-five healthy babies were randomly chosen in Changsha from Jul.2005 to Aug.2005 and their cord blood was drown when they were born. CD4+ and CD8+ counts, CD4+%, CD8+%, CD4+/ CD8+ratios were obtained using flow cytometry analysis. Infant temperament were measured after 1-4 months( mean age 2.52 months) with parent response to carey revised infant temperament questionnaire(EITQ/RITQ) administered.Results The percentage of CD4+ T-cell subsets to total lymphocytes correlated negatively with persistence scores (r=-0.43 P=0.033). However, CD8+%, CD8+ and CD4+ counts, CD4+/ CD8+ ratios were not correlated with temperament traits.Conclusions The lower CD4 %, the better infants' persistence.

Objective:To observe the clinical efficacy of auricular point sticking at different points to relieve the pain in arteriovenous fistula puncture. Methods: A total of 42 patients with arteriovenous fistula were randomized into a Shenmen (TF4) group and an Elbow (SF3) group by the random number table method, with 21 cases in each group. After enrolled into different groups, before the dialysis, patients were given auricular point sticking with Wang Bu Liu Xing ( Semen Vaccariae) seeds at Shenmen (TF4) and Elbow (SF3), respectively. Patients were asked to press the seeds themselves for 2 min each time, four times a day, and an additional 5-15 min before the arteriovenous fistula puncture. Intensive pressing was offered during the puncture, 15-20 presses for each time, and the plasters were changed every 2-3 d. The numerical rating scale (NRS) was used to score the pain level one week before and after auricular point sticking. The NRS score was then compared and analyzed. Results: The intra-group comparison showed that the changes of NRS score in both groups were statistically significant after auricular point sticking (both P＜0.05). After the treatment, there was no significant difference in NRS score between the two groups (P＞0.05). Conclusion: Auricular point sticking at Shenmen (TF4) or Elbow (SF3) can effectively relieve the pain of arteriovenous fistula puncture, and these two points have equivalent analgesic effect.

OBJECTIVETo investigate the time trends and age-related characteristics of mortality and disease burden for cardiocerebrovascular diseases (CVD) in Hunan, China during three periods (1973-1975, 1990-1992 and 2004-2005).

METHODSThe cardiocerebrovascular death data of Hunan residents were collected by three national retrospective sample surveys of death. Cause-specific mortality, proportion, years of potential life lost (YPLL) and associated indicators were identified in the population of Hunan in above mentioned three periods. Time trends of age-specific mortality rate were assessed by fitting curvilinear regression lines and the increase rates of mortality with age were analyzed in each period.

RESULTSThe standard all-cause mortality of residents in Hunan decreased (chi2 = 189.947, P < 0.001, chi2 = 54.201, P < 0.001; chi2 = 27,396.898, P < 0.001) while the standard mortality for CVD increased (chi2 = 54.201, P < 0.001; chi2 = 27,396.898, P < 0.001) from 1973 to 2005. The age-specific mortality rate for CVD increased with age in all three periods, especially for citizens older than 60 years. There were age stages in each period in which the mortality increase rate was the fastest (10-14 and 15-19 years old in 1973-1975; 10-14, 15-19 and over 80 years old in 1990-1992; 15-19 and over 80 years old in 2004-2005). Exponential regression function (y = b0e(b1x)) can be used for the proper description of age-specific mortality change. The ratio of YPLL for CVD in all death causes showed increase trend (chi2 = 275,630.407, P < 0.001). YPLL rate (YPLLs per 1000) in 1973-1975 was higher than those in 1990-1992 and 2004-2005. YPLL rate was positively correlated with mortality in all periods.

CONCLUSIONSThe mortality for CVD increased with time and aging. People older than 60 years were threatened by CVD mostly. Mortality trend analysis also found higher CVD deaths in people age 15-19 in Hunan residents.

Curcumin-ethyl-cellulose (EC) sustained-release composite particles were prepared by using supercritical CO2 anti-solvent technology. With drug loading and yield of inclusion complex as evaluation indexes, on the basis of single factor tests, orthogonal experimental design was used to optimize the preparation process of curcumin-EC sustained-release composite particles. The experiments such as drug loading, yield, particle size distribution, electron microscope analysis (SEM) , infrared spectrum (IR), differential scanning calorimetry (DSC) and in vitro dissolution were used to analyze the optimal process combination. The orthogonal experimental optimization process conditions were set as follows: crystallization temperature 45 degrees C, crystallization pressure 10 MPa, curcumin concentration 8 g x L(-1), solvent flow rate 0.9 mL x min(-1), and CO2 velocity 4 L x min(-1). Under the optimal conditions, the average drug loading and yield of curcumin-EC sustained-release composite particles were 33.01% and 83.97%, and the average particle size of the particles was 20.632 μm. IR and DSC analysis showed that curcumin might complex with EC. The experiments of in vitro dissolution showed that curcumin-EC composite particles had good sustained-release effect. Curcumin-EC sustained-release composite particles can be prepared by supercritical CO2 anti-solvent technology.
