Objective To introduce a novel modified CT severity index based on the assessment of extrapancreatic inflammation and pancreatic necrosis on CT index (EPIPN) and to evaluate its effect in predicting the severity and prognosis of acute pancreatitis. Methods Seventy-seven consecutive patients diagnosed as acute pancreatitis (AP) from August 2006 to December 2007 were retrospectively analyzed. The clinical data included age, sex, cause, the C-reactive protein(CRP) level with in 72 hours of onset of symptom, Ranson signs, the APACHE I1 score, the disappearing time of the abdominal pain, the presence of organ failure, the length of hospital stay, etc. All patients underwent contrast-enhanced multisection CT scan after admission of 48-72 hours. The CT severity index (CTSI) and EPIPN scores were obtained. The severity of pancreatitis for each patient was then categorized as severe if CTSI≥7 or EPIPN>5. The diagnostic value of EPIPN in predicting the severe acute pancreatitis (SAP) was compared with that of CTSI using ROC curve. The correlation of EPIPN or CTSI with clinical coutcome was conducted. Results Of 77 patients, 34 were males and 43 were females with mean age of 51.79 years (age range 22-92 years). The causes of AP were gallstones (63 cases), hyperlipemia (6 cases), alcohol (1 case) and idiopathic (7 cases). Organ system failure was present in 14 (18.2%) of the 77 patients. The area under the ROC curve of CTSI in predicting the SAP was 0.72 (95% CI: 0.59-0.88) with sensitivity of 80.4% and specificity of 55% when CTSI≥7, and that in EPIPN was 0.82 (95% CI: 0.73-0.91) with sensitivity of 91.3% and specificity of 63% when EPIPN >5. EPIPN was well correlated with hospital stay, APACHE Ⅱ score and CRP levels. Conclusions The EPIPN allows accurate estimation of disease severity and prognosis in AP patients. The diagnostic effect of EPIPN for predicting SAP is superior to CTSI. The EPIPN index is-both convenient and practical, and has clinical value.

Objective:To evaluate the utilization of Kanglaite injections in lung cancer patients in 11 hospitals of Zhejiang and analyze the prescription data. Methods: Totally 40-day prescription data of the patients with lung cancer in 11 hospitals of Zhejiang were withdrawn every year from 2009 to 2013. The data in respect of the consumption sum, DDDs, department distribution and medical insurance category of Kanglaite injections were analyzed. Results: The consumption sum of Kanglaite injections used in the patients with lung cancer in 11 hospitals of Zhejiang showed an upward trend year by year, the growth in 2011 and 2012 was the fastest, and the sum in 2012 was 1. 77-fold of that in 2009. The consumption sum proportion of Kanglaite injections in total amount of drug consumption rose after the first drop. The top 3 departments were oncology, radiotherapy and thoracic surgery in the five years. The dosage and DDDs of Kanglaite injections were also in an increase trend year by year, and the growth in 2011 and 2012 was the fastest. Conclusion:The utilization of Kanglaite injections in the patients with lung cancer in Zhejiang area shows a continuous rapid growth momentum, therefore, it is still essential to strengthen the reasonable application in clinics.

Objective To observe the anaesthetic effect of sulfentanil combined with bupivacaine for subarachnoid block on cesarean section patients and the influence on the patient and fetus.Methods Eighty patients who were scheduled for elective cesarean section under subarachnoid block,were distributed into two groups:bupivacaine with no sulfenlanil(group B)and bupivacaine with sulfentanil(group BS).Detected SBP,DBP,MAP,HR,SpO2 before and after anesthesia.The time of drug onset,motor recovery and pain recovery were recorded,the effect of muscle relaxation was evaluated,and the drag reaction,neonatal Apgar score and anesthesia complication were recorded.Results There was no significant difference in the time of drug onset and motor recovery,muscle relaxation,neonatal Apgar score between the two groups.MAP was lower after 3-10 min of anesthesia than before anesthesia,but there was no significant difference after 30-120 min of anesthesia in the two groups.The rate of drag reaction was 27.5% in group B,but no case in group BS.The time of pain recovery was longer in group BS than that in group B(P＜0.01).The rate of temporary itch of skin after operation was 17.5% in group BS.Conclusion The addition of sulfentanil to hyperbaric bupivacaine provides adequate anesthesia for cesarean section and good postoperative analgesia.

Objective To investigate the effects of dexmedetomidine on the end-tidal concentration of sevoflurane during recovery from breast cancer surgery under general anaesthesia. Methods A total of 120 patients undergoing unilateral breast cancer radical operation were randomly divided into four groups:group C (infusion of saline, n=30), group D0.5 [infusion of dexmedetomidine 0.5μg/(kg·h) during operation, n=30], group D0.6 [dexmedetomidine 0.6μg/(kg·h), n=30] and group D0.7 [dexmedetomidine 0.7 μg/(kg · h), n=30]. The end-tidal concentrations of sevoflurane during surgery and postoperation were observed. The end-tidal concentration of sevoflurane on palinesthesia was recorded. The time from stopping administration of anesthetic drug to palinesthesia and the operation time were recorded. The palinesthesia of patients from general anaesthesia and the degree of emergence agitation of the patient were measured using Riker ’s sedation-agitation scale. The operation time, anesthesia time, intraoperative remifentanil dosage, intraoperative auditory evoked potential index (AAI), sevoflurane inhalation concentration and the corresponding time were recorded. Results There were no significant differences in clinical data, remifentanil dosage, operation time and AAI between four groups. The anesthesia time was longer in group D0.7 than that in the other three groups (P<0.05). Compared to group C, the end-tidal concentration of sevoflurane during surgery, postoperation and palinesthesia were lower and the time of palinesthesia was delayed in groups D0.5, D0.6 and D0.7 (P<0.05). And the time of palinesthesia was delayed in group D0.7 than that of group D0.5 and group D0.6. Compared with group C, the ratio of Riker’s sedation-agitation scale>7 was lower in groups D0.5, D0.6 and D0.7 (P<0.05). The ratio of Riker’s sedation-agitation scale>4 was significantly higher in group D0.6 and group D0.7 than that in group C and group D0.5, but the ratio of score>6 was lower (P<0.05). The ratio of score>3 was higher in group D0.7 than that of other three groups (P<0.05). Intraoperative cardiac tachycardia was found in group D0.6 and group D0.7 (4 cases, 13%and 8cases, 7%). Conclusion Sevoflurane inhalation anesthesia and intravenous infusion of dexmedetomidine 0.6μg/(kg·h) can effectively reduce intraoperative sevoflurane dosage, the end-tidal concentration of sevoflurane during recovery, and the occurrence of agitation in patients undergoing general anesthesia.

Objective To investigate the blood perfusion characteristic of acute pancreatitis (AP) using multisection dynamic CT. To detect the changes of the perfusion parameters in patients with AP and assess the value of the perfusion parameters as severity indicators in AP. Methods 120 cases (34 cases of normal pancreas and 86 cases of AP) were examined for pancreatic perfusion from August 2006 to April 2008. The multisection dynamic CT perfusion series was performed by a multisection CT scanner (Siemens somatom Sensation 64) and the perfusion parameters, including BF, BV, TTP, PS, were collected and were compared with APACHE Ⅱ score, Ranson score, CRP, CTSI, time to abdominal pain cessation, length of hospital stay and complication rate for correlation analysis. Results The mean BF, BV, TTP and PS in AP patients were (113.57 ±50.04) ml · 100 mg~(-1) · min~(-1), (146.61 ±45.11) ml/L, (148. 88 ±21. 16) 0.1 s, (119.53± 52.36) 0. 5 ml · 100 ml · min , respectively; when compared with normal control, BF, BV decreased significantly (P<0.05) , while the change of TTP, PS were not statistically significant. Both BF and BV were correlated with APACHE II score, Ranson score, CRP, CTSI (P<0. 05) , as well as the time to abdominal pain cessation, length of hospital stay and complication rate (P < 0. 05). Conclusions Pancreatic vessel perfusion was decreased in AP. Both BF and BV were correlated with APACHE Ⅱ score and Ranson score, CRP, CTSI, and could be used to predict severity of acute pancreatitis.
