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 evaluate the correlation of the ion selectivity electrode assay and arsenazo Ⅲ assay for serum calcium determination and compare the differences between two methods.Methods 142 serum samples were collected from patients and detected by ion selectivity electrode assay and arsenazo Ⅲ assay,the differences of two methods were compared,person correlation and Bland -Altman was used to discuss the correlation.Results The serum calcium concentration detected by ion selectivity electrode assay was (2.23 ±0.10)mmol/L and detected by arsenazo Ⅲ assay was (2.24 ±0.12)mmol/L,the difference between the two methods was not statistically significant (t =-1.09,P >0.05).The person correlation analysis demonstrated that the two methods had a positive correlation (r =0.393,P <0.01).The Bland -Altman consistency analysis showed that ion selectivity electrode assay was agreed with arsenazo Ⅲ assay.Conclusion The two methods for serum calcium concentration determination,the ion selectivity electrode assay was coincidence with the arsenazo Ⅲ assay.

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.

OBJECTIVETo observe the efficacy of Xingnaojing Injection (XI) in treatment of sepsis-associated encephalopathy (SAE).

METHODSTotally 65 SAE patients were retrospectively analyzed at EICU from September 2010 to September 2013. They were assigned to the control group (32 cases) and the treatment group (33 cases) according to whether they received XI. Patients in the control group received anti-infection and symptomatic support, while those in the treatment group were intravenously injected with XI at 20 mL per day for additional 7-10 days. The fever clearance time, Glasgow coma scale (GCS), C-reactive protein (CRP), neuron-specific enolase (NSE), and improvement of electroen-cephalogram (EEG) were observed in the two groups.

RESULTSCompared with the control group, the fever clearance time was shortened, CRP levels decreased, GCS score and efficacy of EEG was alleviated in the treatment group after treatment with statistical difference (P < 0.05). No adverse reaction occurred during medication.

CONCLUSIONX1 was safe and effective in treatment of SAE.

Hexafluoroisopropanol (HFIP)-induced sodium dodecyl sulfate/dodecyltrimethylammonium bromide (SDS/DTAB) catanionic surfactant coacervate extraction method coupled with high performance liquid chromatography (HPLC) was used to detect the migration of phthalates from disposable tablewares to drinking water. The concentration factors are larger than 82 and extraction recoveries over 53%for water samples spiked with 100 or 200 ng/mL phthalates. Limit of detection is in the range of 1.0–2.6 ng/mL. Good linearity with correlation coefficients larger than 0.9985 is obtained in the concentration of 20–1500 or 40–3000 ng/mL. Relative recoveries are from 82.4%to 123.6%for water samples spiked with 30/60, 250/500, and 1500/3000 ng/mL phthalates, respectively. Relative standard deviations (RSDs) are 0.4%–7.4% for intraday precision (n ? 5) and 0.6%–7.8% for interday precision (n ? 3). Four of studied phthalates are found in the drinking water samples prepared from four kinds of tablewares.

Objective To evaluate the effects of dexmedetomidine on the expression of aquaporins 1 (AQP1) and AQP5 during lung ischemia/reperfusion (I/R) in rats in an in vitro experiment.Methods SPF healthy male Sprague-Dawley rats,aged 3-4 months,weighing 250-320 g,were used in this study.Forty-five isolated rat lungs in which the model of isolated lung perfusion was successfully established were divided into 3 groups (n=15 each) using a random number table:sham operation group (S group),I/R group and dexmedetomidine group (D group).The isolated rat lungs were continuously perfused for 150 min in group S.After 15 min of perfusion,the isolated rat lungs were subjected to 60 min of ischemia and apnea followed by 75 min of ventilation and reperfusion to establish the model of isolated lung I/R injury in group I/R.In group D,the isolated rat lungs were perfused for 15 min with K-H perfusion fluid containing 10 nmol/L dexmedetomidine,and then subjected to 60 min of ischemia and apnea followed by 75 min of ventilation and reperfusion with K-H perfusion fluid containing 10 nmol/L dexmedetotnidine.The lung compliance,airway resistance,perfusion flow and partial pressure of arterial oxygen (PaO2) were recorded at 10 min of perfusion and 15,45 and 75 min after restoration of perfusion.Lung tissues were obtained at 75 min after restoration of perfusion for determination of wet/dry weight ratio (W/D ratio) and for examination of the pathological changes and changes in the uhrastructure.The expression of AQP1 and AQP5 protein and mRNA in lung tissues was detected by Western blot and real-time polymerase chain reaction,respectively.Results Compared with S group,the airway resistance was significantly increased and lung compliance,perfusion flow and PaO2 were decreased during reperfusion,and W/D ratio was increased in I/R and D groups (P＜0.05),the expression of AQP1 and AQP5 protein and mRNA in lung tissues was significantly down-regulated in group I/R,and the expression of AQP 1 and AQP5 protein and mRNA in lung tissues was significantly up-regulated in group D (P＜0.05).Compared with I/R group,the airway resistance was significantly decreased and lung compliance,perfusion flow and PaO2 were increased during reperfusion,W/D ratio was decreased,the expression of AQP1 and AQP5 protein and mRNA in lung tissues was up-regulated (P＜0.05),and the pathological changes of lung tissues was significantly attenuated in group D.Conclusion The mechanism by which dexmedetomidine reduces I/R injury may be related to up-regulation of the expression of AQP1 and AQP5 in rats in an in vitro experiment.

Objective To investigate the changes of the cell cycle regulators ATM, Chk2 and p53 and cell cycle arrest in HeLa cells after cisplatin therapy. Methods The proliferation-inhibiting rates of HeLa cells induced by eisplatin of different concentrations were measured by MTT assays. The mRNA and protein expressions of ATM, Chk2 and p53 of HeLa cells with and withont cisplatin were detected by RT-PCR and Western blot, respectively. The cell cycle analysis was conducted by flow cytometric analysis. Results Cisplatin inhibited the proliferation of HeLa cells in a dose- and time-dependent manner. The mRNA and protein expressions of ATM, Chk2 and p53 were increased in HeLa cells treated with cisplatin. The cell cycle was arrested in G2/M phase in HeLa cells treated with cisplatin. Conclusion Activation of ATM, Chk2 and p53 might be critical in determining whether cells survive or undergo apoptesis. Targeting ATM, Chk2 and p53 pathway might he a promising strategy for reversing chemoresistance to clsplatin in cervical cancer.
