Objective To investigate whether antipsychotic drugs will increase the risk of venous thromboembolism (VTE) and pulmonary embolism (PE), and to provide evidence for the prevention of VTE and PE in patients with APs exposure. Methods Databases including PubMed, Web of Science, CNKI, VIP and Elsevier were searched from inception to July 2016 to collect case-control studies and cohort studies on the association between APs exposure and the risk of VTE and PE. The literature were screened according to the inclusion and exclusion criteria, the data were extracted and the bias risk of the included studies were evaluated by two reviewers independently. The Meta-analysis was performed by using Stata 12 software. Results Nineteen studies were included. The results of meta-analysis showed that APs exposure was associated with VTE (OR=1.50, 95%CI 1.30 to 1.74,P<0.001). Exposure to low-potency FGA (OR=2.28, 95%CI 1.02 to 5.10,P=0.045), high-potency FGA (OR=1.68, 95%CI 1.37 to 2.05,P<0.001) and SGA (OR=1.74, 95%CI 1.24 to 2.44,P=0.001) revealed an increased risk of VTE. Exposure to APs also signi?cantly increase the risk of PE (OR=3.69, 95%CI 1.23 to 11.07,P=0.02), especially exposure to FGA (OR=2.54, 95%CI 1.22 to 5.32,P=0.013), but exposure to SGA could not revealed an increased risk of PE. Conclusion FGA and SGA exposure maybe associated with an increase in the risk of developing VTE. And exposure to the FGA could increase the risk of PE. The occurrence of VTE and PE should be monitored when taking Aps.

ObjectiveTo evaluate the incidence of osteoporosis and relevant factors in the elderly male patients with chronic obstructive pulmonary disease(COPD).Methods Forty elderly male patients with COPD were enrolled and thirty age-matched healthy subjectss were enrolled.The BMD of lumbar vertebrae and proximal end of the femur were measured by dual energy X-ray absorptiometry.Serum levels of osteocalcin （BGP）and lung function were measured while blood-gas analysis of arterial blood was conducted.Results The BMD of lumbar vertebrae and proximal end of the femur(including lumbar 1 to 4，femoral neck，wards triangle，trochanter and shaft) in the COPD group were significantly lower than those in the control subjects(all Plt;0.01).Serum BGP level in the COPD group was higher than that in the control group[(5.67±1.59)ng/mL vs (4.37±1.47)ng/mL，Plt;0.01).The prevalence of osteoporosis among the COPD patients was significantly higher than that among the control subjects（65% vs 40%，50% vs 20%，both Plt;0.05）.BMD in the COPD patients who had a history of smoking was significantly lower than those who did not smoke cigarettes（Plt;0.01 or Plt;0.05）.BMD in the COPD patients treated with glucocorticoid were significantly lower than those who were not receiving glucocorticoid therapy(Plt;0.01 or Plt;0.05).BMD was positively correlated with PaO2，BMI，FEV1%pred and FEV1/FVC(Plt;0.01 or Plt;0.05).Conclusions Compared with age-matched normal controls，BMD in elderly male COPD patients are significantly lower with increased osteoporosis risk.Osteoporosis induced by COPD is high change-over pattern. BMD in patients with COPD may be correlated with hypoxia，lung function，smoking，low body mass index and glucocorticoids therapy.
Objective To summarize the nutritional management strategies of patients undergoing electively gastrointestinal surgery. Methods This article reviewed the recent researches on perioperative nutritional management in electively gastrointestinal surgery, including four major directions: preoperative nutritional evaluation, glucose level control, nutritional type, and immunonutrition. Results At present, preoperative nutritional evaluation methods included anthropometry, laboratory tests, subjective global assessment (SGA), nutritional risk screening (NRS) 2002, Reilly nutritional risk screening, nutritional risk indicator (NRI), and so on. For preoperative nutritional assessment system, however, current data could not single out superiority for any nutritional assessment methods in the ability to predict surgery-related complications. The usage of enhanced recovery after surgery (ERAS) protocol to reduce surgical stress and preclude postoperative insulin resistance had recently been clearly linked to reductions in postoperative morbidity and adverse outcomes. There were specific criterias for perioperative parenteral and enteral nutrition in undernourished patients, who were defined in clinical guidelines recently, such as the Guidelines for Adult Perioperative Nutrition Support issued by Chinese Society of Parenteral and Enteral Nutrition (CSPEN). Several systematic reviews showed that immunonutrition could reduce both morbidity and length of stay after major electively gastrointestinal surgery. Conclusion Perioperative nutritional management can ensure patients benefit from nutritional support by nutritional assessment, can reduce the nutritional risk and metabolic disorder caused by operation, can achieve the goal of optimal nutrition support in surgical patients, and can ultimately reduce postoperative complications.
ObjectiveTo compare the indirect calorimetry (IC) measured resting energy expenditure (MREE) with adjusted Harris-Benedict formula calculating resting energy expenditure (CREE) in the mechanically ventilated surgical critically ill patients and to evaluate the relationship between the resting energy expenditure (REE) with the severity of illness. MethodsTwenty-one patients undergonging mechanical ventilation for critical illness in the intensive care unit of general surgery between August 2008 and February 2010 were included in this study. Data during the study period of nutrition support were collected for computation of the severity of critical illness by acute physiology and chronic health evaluation Ⅱ scores (APACHE Ⅱ scores) and organ dysfunction scores (Marshall scores). MREE was measured by using IC of the MedGraphics CCM/D System within the first 7 d after nutrition therapy. CREE was calculated by using the HarrisBenedict formula adjusted with correction factors for illness at the same time. According to APACHE Ⅱ scores on admission, the enrolled patients were divided into two groups: APACHEⅡ score ≥20 scores group (n=8) and APACHE Ⅱ score lt;20 scores group (n=13), and the differences between MREE and CREE of patients in two groups were determined. ResultsThe reduction of variation tendency in CREE other than MREE in the enrolled patients within the first week of nutritional support was statistical significance (Plt;0.001). The CREE of patients 〔(1 984.49±461.83) kcal/d〕 was significantly higher than the MREE 〔(1 563.88±496.93) kcal/d〕 during the first week of nutritional support (Plt;0.001). The MREE on the 0, 1, 2, and 4 d after nutrition therapy were statistically significant lower than CREE at the same time interval in these patients (Plt;0.01), and the differences at the other time points were not significant (Pgt;0.05). There was a trend towards a reduction in APACHE Ⅱ and Marshall scores within the first week of nutrition therapy that reached statistical significance (Plt;0.001). During the first week of nutrition therapy, APACHEⅡ and Marshall scores of patients in ≥20 scores group were significantly higher than those in lt;20 scores group, respectively (Plt;0.05 or Plt;0.01), and the reductions of APACHE Ⅱ scores and Marshall scores were significant in patients of two groups (Plt;0.001). A significant positive correlation was found between CREE with APACHE Ⅱ scores (r=0.656, Plt;0.001) and Marshall scores (r=0.608，Plt;0.001) in patients within the first week after nutrition support. Although no statistically significant correlation was observed between MREE and APACHEⅡ scores (r=-0.045， P=0.563), a significant positive correlation was observed between MREE and Marshall scores (r=0.263, P=0.001) within the first week after nutrition therapy. There was no correlation between MREE and CREE (r=0.064, P=0.408) in patients at the same time interval. The reduction of MREE of patients in ≥20 scores group other than in lt;20 scores group was statistically significant within the first week after nutrition therapy (P=0.034). In addition, the MREE of patients in ≥20 scores group were not significantly different from those in lt;20 scores group (Pgt;0.05), and the mean CREE was not different in two groups patients within the first week of nutritional therapy 〔(1 999.55±372.73) kcal/d vs. (1 918.39±375.27) kcal/d, P=0.887〕. CREE was significantly higher than MREE of patients in ≥20 scores group within the first week except the 3 d and 5 d after nutrition therapy (Plt;0.05), while in lt;20 scores group CREE was significantly higher than MREE in patients only within the first 3 d after nutrition therapy (Plt;0.05 or Plt;0.01). MREE and CREE of patients in ≥20 scores group were not different from those in lt;20 scores group, respectively (Pgt;0.05).
Objective To investigate the effectiveness of double-needle suture for mixed meniscus tear repair under arthroscope. Methods Between April 2006 and January 2011, 22 patients with mixed meniscus tear were treated with double-needle suture under arthroscope. There were 14 males and 8 females, aged 18-41 years (mean, 31.3 years). All injuries were caused by sports. The time between injury and admission ranged from 2 days to 4 years (median, 11 months). International Knee Documentation Committee (IKDC) score was 42.5 ± 15.2, Lysholm score was 45.5 ± 13.5, and Tegner score was 2.9 ± 1.6. Seventeen cases complicated with anterior cruciate ligament injury. Results Healing of incision by first intention was achieved in all patients. No injury of nerve and blood occurred. The patients were followed up 12-48 months with an average of 27.6 months. According to Barrett et al. standard, 19 cases (86%) got clinical healing. The IKDC, Lysholm, and Tegner scores were improved to 77.1 ± 8.9, 79.8 ± 9.9, and 6.8 ± 1.6 respectively at last follow-up, showing significant differences when compared with preoperative scores (P lt; 0.05). Conclusion Arthroscopic meniscus repair using double-needle suture can provide good effectiveness because it has high firmness.
Objective To assess the risk factors associated with postoperative infection after elective abdominal operation for elderly in department of general surgery. Methods One hundred and fifty-nine consecutive elderly patients admitted to the department of general surgery in our hospital for elective abdominal operation between May 2010 and February 2012 were considered for inclusion and retrospectively analyzed. Thirty-eight patients （23.90%）with postoperative infection were taken as the infection group and 121 patients without postoperative infection as noninfection group. The differences in the objective physiological indicators， subjective health status indicators， operation status， the incidence of postoperative infective complications， and mortality were compared between the two groups. Results Of enrolled 159 patients in this study， the incidence of postoperative infective complications was 23.90% （38/159）； 2 patients died， and the postoperative mortality rate was 1.26%. Single factor and multivariate logistic regression analysis showed that preoperative malnutrition risk， history of diabetes， and chronic respiratory system disease were the independent risk factors of postoperative infection complications in elective abdominal surgery for elderly patients. Conclusion Improving preoperative respiratory function， diabetes mellitus， and nutritional status would help to reduce incidence of postoperative infection for elderly patients with elective abdominal operation.
COPD 是一種可預防、可治療, 以氣流不完全可逆受限并呈進行性發展為特征的疾病, 與肺部對有害氣體或有毒顆粒的異常炎癥反應有關。在全球范圍內COPD 是引起死亡和功能致殘的主要疾病之一。COPD 在全球患病率和死亡率位居第四, 并呈不斷上升的趨勢[1] 。本病具有明顯的肺外效應, 包括引起全身系統性炎癥、代謝改變、神經激素激活,以及對肌肉骨骼、心血管系統等其他系統的影響等[2] 。既往認為COPD 僅引起紅細胞增多, 但近期研究發現COPD 引起的系統性炎癥可影響紅細胞的生成, 貧血亦同樣存在于部分COPD 患者。目前認為, COPD導致的貧血與其他許多慢性疾病如慢性心衰一樣, 同屬于一種慢性病性貧血( anemia of chronic disease, ACD) , 稱為COPD 相關性貧血, 其患病率高于繼發性紅細胞增多癥在COPD 的患病率[3-5] 。本文就COPD 相關性貧血的流行病學概況、病理生理機制、臨床重要性及干預的最新研究進展如下綜述。
Objective To estimate the effects of N-acetylcystein (NAC) combined with conventional treatment on the patients with stable COPD. Methods Literatures published between January 1995 and September 2010 were searched in the databases including PubMed, CHEST, CNKI, CBM, VIP and WANGFANG for collecting the randomized control trials (RCTs) of NAC combined with the conventional treatment versus the conventional treatment on patients with stable COPD. The studies were screened according to the inclusive and exclusive criteria, the data were extracted, the quality was assessed and the meta-analysis was conducted with RevMan 5.0 software. Results A total of seven RCTs including 404 patients with stable COPD were enrolled. The meta-analysis demonstrated that, a) the short-term usage of NAC could improve PaO2 (SMD=0.05 mmHg, 95%CI –0.23 to 0.32) and PaCO2 (SMD= –0.29 mmHg, 95%CI –0.76 to 0.17) without significant differences compared with the control group; and b) the NAC could significantly improve FEV1 (SMD=1.11L, 95%CI 0.69 to 1.50) and clinical symptoms (RR=17.32, 95%CI 7.11 to 42.18), and reduce the frequency of acute exacerbation (RR=0.20, 95%CI 0.07 to 0.54) with significant differences. Conclusion The NAC used in a short-term can significantly improve arterial blood gas (ABG) and pulmonary function, and it can improve clinical symptoms and reduce the frequency of acute exacerbation. But for the possibility of moderate bias due to lower quality of the included studies and unclear implementation of RCTs, this conclusion should be cautiously applied in clinic with patients’ conditions in considered and it has to be verified with more large-scale and high-quality RCTs.

Methods Using a self-designed questionnaire in March 2010, we did a survey on students who attended the course of hospital infection control and occupational protection. Results Among all the students, 92.73% did not know standard prevention measures, and the correct treatment and remedial measures for sharp injuries; 27.27% did not know gloves should be worn at the time of blood drawing; 25.45% did not know the "six-step" hand-washing; and less than one out of ten students used hospital laundry to wash their uniform. Conclusions The students have a low level of relevant knowledge on occupational protection, and their protection behaviors were not complete or standard. Therefore, the teaching should help and support students to have a concept of standard prevention, and acquire sound knowledge and behavior of occupational protection in order to avoid and reduce the risk factors from their future clinical practices.
