Objective To compare the effect of active compression-decompression cardiopulmonary resuscitation(ACD-CPR) with standard- cardiopulmonary resuscitation(S-CPR) on ventricular function in a canine ventricular fibrillation model. Methods Ventricular fibrillation was induced in anesthetized and instrumented canine. Twenty-four dogs were randomly assigned to either ACD-CPR group or S-CPR group.After 4 minutes of untreated VF,two-dimension echocardiography was used to evaluate the left ventricular end-diastolic volume(LVEDV),left ventricular end-systolic volume(LVESV) and left ventricular ejection fraction (LVEF) of every canine of the two groups when they were undergoing cardiopulmonary resuscitation. Results During ventricular fibrillation, both ACD-CPR group and S-CPR group showed decreased LVEDV compared with pre-ventricular fibrillation, but not statistically significant( P >0.05).LVEDV was increased in ACD-CPR group compared with S-CPR group, but not statistically significant (P> 0. 05). Both ACD-CPR group and S-CPR group showed significantly increased LVESV compared with pre-ventricular fibrillation,of which the difference was statistically significant ( P <0. 001). Both ACD-CPRgroup and S-CPR group showed significantly decreased LVEF compared with pre-ventricular fibrillation,of which the difference was statistically significant (P <0. 001). LVEF was increased in ACD-CPR group compared with S-CPR group,of which the difference was statistically significant ( P = 0.019). Conclusions Compared with S-CPR,ACD-CPR resulted in higher LVEF.

Objective To raise the awareness of acute kidney injury (AKI) and improve the level of diagnosis.Methods All the hospitalized adult patients in the Affiliated People's Hospital of Shanxi Medical University from January 2012 to July 2013 were screened.Those patients diagnosed as AKI were retrospectively analyzed in terms of incidence,the rate of missed diagnosis,etiology,distribution and prognosis of AKI.Results (1) The incidence of AKI in the patients was 0.67% (381/56 835),the ratio of male to female was 1.91 ∶ 1,and the average age was (63.45±16.95) years.(2)There were 321 cases diagnosed as pre-renal AKI (84.25%),42 cases diagnosed as renal AKI (11.02%) and 18 cases diagnosed as post-renal AKI (4.72%).(3)There were 189 cases(49.61%) missed diagnosed among all the screened cases.The rates of missed diagnosis in neurosurgery,general surgery and cardiac surgery department was 62.96%,59.09% and 50.00%,in cardiology,respiratory and neurology department was 50.00%,50.00% and 45.45% respectively.(4) Multivariate Logistic regression analysis showed that hypertension [odds ratio(OR)=1.631],renal replacement therapy(RRT)(OR=23.256) and oliguria history (OR=1.936) were independent risk factors of missed AKI diagnosis.Conclusion The missed diagnosis rate of AKI is high and has certain characteristics in different departments.Hypertension,RRT and oliguria history are independent impact factors of missed AKI diagnosis.

OBJECTIVETo explore the procedures of dynamic infusion cavernosometry and cavernosography (DICC) and their application in the diagnosis and classification of venous erectile dysfunction (VED).
METHODSThis study included 103 ED patients, aged 20 to 43 years, highly suspected of VED, with disease courses of 4 months to 6 years. DICC was performed and analyses were made on the results, especially the parameters of flow-to-maintain (FTM) and pressure decay (PD) in the corpus cavernosum.
RESULTSBased on the parameters of FTM and PD, 21 of the patients were normal, 5 were suspected of VED, 39 had mild VED, 25 had moderate VED, and 13 had severe VED. Penile subcutaneous hematoma was found in 4 of the patients, all recovered after 3 to 5 days, with no other complications.
CONCLUSIONDICC is a reliable, safe and minimally invasive method for the diagnosis and classification of VED.

Bioimprinting is a new developed technique to improve the characteristics of enzymes.Bioimprinting by lauric acid was conducted to improve the esterification activity of lipase PS in sol-gel immobilization process with methyltrimethoxysila(MTMS) and tetramethoxysila(TMOS) as the precursors.Results generated by checking the esterification activity and scanning electron microscope showed that bioimprinting can enhance the specific activity and thermal stability of lipase PS.The bioimprinting system was optimized by orthogonal experiment,and the optimal condition for lipase bioimprinting is water/silane molar ration(R) 12,polyethylene glycol(PEG) 120?l,and lauric acid 0.15 mmol.Compared with the free enzyme and the non-imprinted enzymes,the specific activity of imprinted enzymes has been improved 44.3 fold and 2.4 fold,respectively.Imprinted lipase show better thermal stability,and the relative activity is 58% after incubated in 80 ℃ for 0.5 h,while no activity was detected for the free enzyme.

AIM:To investigate the effect of vitrectomy in treatment of metal intraocular foreign bodies and the factors affecting visual prognosis.
METHODS:Fourty seven cases ( 48 eyes ) with foreign bodies from January 2010 to June 2013 in our hospital underwent vitrectomy combined with intraocular foreign body removal were retrospectively analyzed. The changes of visual acuity, the size of foreign body, the complications of preoperative, and the relationship between treatment time and visual acuity were recorded.RESULTS: Totally 46 eyes were successfully removed the complete foreign body, 2 eyes of orbital foreign bodies had not been removed. After 6mo of followed-up, the best corrected visual acuity were all improved in varying degrees (P<0. 05), intraocular foreign body size combined with retinal detachment was the risk factor for visual impact (P<0. 05).
CONCLUSION:Vitrectomy has obvious advantages in the treatment of metal intraocular foreign bodies. Timely and appropriate vitrectomy is very important to the recovery of visual function.

The tissue-specific and MeJA-induced transcriptional levels of BcUGT3 and BcUGT6 in Bupleurum chinense were analyzed in the present study. The transcriptional levels of BcUGT3 in root, leaf, flower and fruit were similar and they all were higher than those in stem. The transcriptional level of BcUGT6 was the highest in leaf and the lowest in flower among in all tested tissues. With non-treated adventitious roots as control, BcUGT6's transcriptional levels were elevated to nearly 2 folds for 2 h, 8 h, 24 h, 2 d and 4 d in MeJA-treated adventitious roots of B. chinense. It showed that the transcriptional level of BcUGT6 was slightly affected by MeJA. While, BcUGT3's transcriptional levels were gradually elevated, and till 4 d after MeJA treatment, the expression level was about 7 folds than that of non-treated control. Using pET-28a (+), the expressions of two genes was investigated. Induced by IPTG, the target proteins were expressed in E. coli and then purified. All the results obtained in the present study will be helpful for follow-up bio-function analysis of BcUGT3 and BcUGT6.

OBJECTIVE: To explore the effects of Salvia miltiorrhiza on renal morphology and renal function of rats with streptozotocin diabetes. METHODS: Thirty male Wistar rats were randomly divided into three groups, which were normal control group, untreated group and Salvia miltiorrhiza-treated group. Diabetic nephropathy was induced in rats of the last two groups by intraperitoneal injection of streptozotocin after unilateral nephrectomy. Then the rats in the normal control and untreated groups were fed with normal saline while those in the Salvia miltiorrhiza-treated group were fed Salvia miltiorrhiza preparation for 8 weeks. The glomerular volume (VG), kidney-to-body weight ratio (KW/BW), urinary albumin excretion rate (UAER) and creatinine clearance (Ccr) were observed. The expression levels of transforming growth factor-beta1 (TGF-beta1), connective tissue growth factor (CTGF), fibronectin (FN) and plasminogen activator inhibitor-1 (PAI-1) were detected by real-time quantitative reverse transcriptase-polymerase chain reaction (RT-PCR) at the end of the experiment. RESULTS: UAER, Ccr, VG and KW/BW ratio were significantly higher in the untreated group than those in the normal control group (P<0.05). The expression levels of TGF-beta1, CTGF, PAI-1 and FN in the untreated group were also significantly higher as compared with those in the normal control group (P<0.05). UAER, Ccr, VG, KW/BW ratio and the levels of TGF-beta1, CTGF, PAI-1 and FN in the Salvia miltiorrhiza-treated group were obviously lower than those in the untreated group (P<0.05). CONCLUSION: Salvia miltiorrhiza can protect rats with streptozotocin diabetes from diabetic nephropathy by suppressing the over-expressions of TGF-beta1, CTGF, PAI-1 and FN in renal cortex.
