Objective To evaluate the relationship between classification of clinical,the infarct size in patients with acute cerebral infarction and electrocardiographic(ECG)changes.Methods The ECG were done in 216 patients with acute cerebral infarction.ECG results of the patients were analyzed according to classification of the Oxfordshire Commumity Project Criteria(OCSP)and infarct size.Results The rates of ECG abnormality in classification of OCSP were 95.5% for total anterior circulation infarction(TACI),80.4% for partial anterior circulation infarction(PACI),62.5% for posterior circulation infarction(POCI)and 48.5% for lacunar cerebral infarction(LACI).The rates of ECG abnormality of TACI and PACI were signficantly higher than that of group of LACI(P

Objective To validate the accuracy of the revised Atlanta classification (RAC) and the determinant-based classification (DBC) for severity of acute pancreatitis.Methods We retrospectively analysed the clinical data from 192 patients with acute pancreatitis who were admitted to our hospital between January 2014 and October 2014.Using the RAC and the DBC,The duration of total parenteral nutrition,length of ICU and hospital stay,operation rate and mortality were assessed in the subgroups,respectively.Results Fluid collections in and around the pancreas was present in 74 patients (38.5％),pancreatic or peripancreatic necrosis in 51 (26.6％),and infection in 18 (9.4％).On the basis of the RAC,106 patients (55.2％),77 patients (40.1％),and 9 patients (4.7％) were classified to have mild,moderately severe,or severe AP,respectively.On the basis of the DBC,11l (57.8％),62 (32.3％),14 (7.3％),and 5 (2.6％) patients were classified to have mild,moderate,severe,or critical AP,respectively.The different categories of severity for each classification system were significantly associated with the duration of total parenteral nutrition,the length of ICU and hospital stay,the operation rate and mortality.Conclusion Both the RAC and DBC accurately classified the severity of AP and differentiated prognosis in the subgroups of patients.

Objective To investigate the incidence and risk factors of postcholecystectomy syndrome (PCS), and provide theoretical basis for the prevention of PCS. Methods A total of 338 patients with PCS were randomly selected in our hospital from May 1st 2013 to April 30th 2014, in which 316 cases were successful followed up including 101 males and 215 females. The data were collected from the 7 aspects including blood type, drinking history, smoking history, diabetes history, mental anxiety, dietary tendence and preoperative symptoms, and which were analyzed by binary-logistic regression analysis. Results According to the PCS diagnostic criteria, 115 patients were diagnosed with PCS (36.39%). The anxiety status and preoperative discomfort were closely related to the occurrence of PCS, with statistically significant difference (P<0.05). Conclusion The diagnosis and treatment of PCS are more complicated. We should focus on the prevention of PCS according to its risk factors, and pay attention to preoperative communication and individualized analysis of patients in order to reduce the occurrence of PCS.

Infected pancreatic necrosis (IPN) is a serious complication which may cause organ failure and death in patients with acute pancreatitis. Surgical debridement is an important therapeutic approach for IPN. With the development of evidence-based medicine, more and more high-level evidences emerge for surgical debridement of pancreatic necrosis tissue, and the traditional treatment strategy has also changed. In the era of minimally invasive surgery, whether 'delayed surgery' should still be executed and how to achieve 'delayed surgery' are the research hotspots in the treatment of IPN. Research evidences reveal that the 'step-up' strategy is not the best strategy for all IPN patients, and alternatives should be explored. In addition, the indications, advantages and disadvantages of open surgery, surgical minimally invasive surgery and endoscopic surgical debridement of pancreatic necrosis tissue have been widely discussed in recent years, and no consensus has yet been reached. At present, the personalized, multidisciplinary, and minimally invasive treatment of IPN is still the mainstream development direction. The authors investigate the timing and strategy of surgical treatment for IPN in order to provide theoretical basis for clinical practice.

Objective To determine the effect of video-assisted retroperitoneal debridement in treatment of infected necrotizing pancreatitis.Methods The clinical data of patients with infected necrotizing pancreatitis was retrospectively analyzed.Heart rate,mean arterial pressure,body temperature and indicators for inflammatory response including level of WBC,CRP and procalcitonin before and after VARD treatment were compared.Results After VARD treatment,the heart rate (preoperative vs.postoperative 8 h,108 ± 22/min vs.95 ± 17/min),mean arterial pressure (preoperative vs.postoperative 12 h,66 ± 18 mmHg vs.79 ± 19 mmHg) and body temperature(preoperative vs.postoperative 24 h,38.3 ± 1.7 ℃ vs.37.3 ± 1.3 ℃) improved significantly (all P ＜ 0.05).Level of WBC [preoperative vs.postoperative 48 h,(13.8 ±6.6) × 109/L vs.(10.1 ±5.2) × 109/L],CRP(preoperative vs.postoperative 48 h,145 ± 88 mg/L vs.95 ± 4 mg/L) and procalcitonin (preoperative vs.postoperative 48 h,1.4 ± 0.7 μg/L vs.0.9 ± 0.4 μg/L) also decreased significantly(all P ＜ 0.05).Conclusions VARD therapy can significantly reduce systemic inflammation and improve the general condition of infected necrotizing pancreatitis patients.

Objective To determine the effects of cyclooxygenase-2 (COX-2) on risk stratification and prognosis of patients with gastrointestinal stromal tumor (GIST).Methods Literatures in the Cochrane libraries of clinical comparative trials,PubMed,EMBASE,Cancer Lit and Chinese BioMedical Literature from 1966 to 2012 were retrieved using the Cochrane systematic evaluation method.The original data were extracted and crosschecked by 2 reviewers.The indicator for assessment including positive rates of COX-2 in GIST patients with different tumor diameters (＜5 cm versus ≥5 cm),mitosis of cancer cells (＜5/50 HPF versus ≥5/50 HPF) and National Institute of Health (NIH) risk stratifications (very low + low versus intermediate + high).The relationship between COX-2 expression and recurrence and metastasis of GIST was evaluated.All the data were analyzed using the RevMan 5.1 software with Meta analysis.The heterogeneity between studies was analyzed using the I2.The binary data were presented by odds ration (OR) and 95％ confidence interval (95 ％ CI).Results Seven articles with a total of 415 patients were included in the analysis.The COX-2 expression did not correlate with the tumor diameters,NIH risk stratifications and tumor metastasis and recurrence (OR =0.60,0.72,2.46,P ＞ 0.05),but with the mitosis of cancer cells (OR =0.46,P ＜ 0.05).Conclusion COX-2 expression is partly correlated with risk stratification of GIST,but has no effect on the prognosis.

Objective To observe the effects of hyperbaric oxygen therapy(HBOT) on Glasgow coma scale(GCS) in patients with traumatic brain injury(TBI) and the influences of course and initiating time of HBOT on the therapeutic effects.Methods 105 cases of TBI patients,which performed HBOT more than 30 days in HBOT Center of Southwest Hospital,were analyzed retrospectively.The GCS improvements were compared with 29 cases of TBI patients without HBOT during the same period.They were also compared between patients with different severity,initiating times and courses of HBOT.Results The GCS improvement of patients with HBOT was 3.97?2.65,especially in severe TBI patients(5.22?2.49),Both were higher than that without HBOT(2.38?2.16)(P

Objective To evaluate the MRI and clinic types of oxfordshire community stroke project(OCSP)in the diagnosis of acute young ischemic stroke patients.Methods 1 64 young patients (18-45 years)and 228 old patients (>60 years)with acute ischemic stroke were analyzed retrospectively.There are four groups according to MR and clinic types of OCSP:total anterior circulation infarct (TACI),partial anterior circulation infarction (PACI),posterior circulation infarction(POCI)and lacunar infarction (LACI).Results Cerebral infarction showed a mild hypo-signal on T1 WI,hyper-signal on T2 WI,FLAIR and DWI.Among the 164 young patients,8 (4.88%)were classified as TACI,72 (43.90%)as PACI,30 (18.29%)as POCI and 54 (32.93%)as LACI.Young and old group image types comparison,χ2 = 1.221,P >0.05.Young stroke patients image and clinical types comparison,Kappa =0.525,P <0.05.Conclusion OCSP imaging types has a good consistency with clinical types,which helps to evaluate ischemic stroke objectively in youth.
