Objective To assess the value of intra-aortic balloon pump (IABP) support in patients with acute myocardial infarction (AMI) complicated by cardiogenic shock (CS) undergoing percutaneous coronary intervention (PCI). Methods The clinical data of 41 patients with AMI complicated by CS receiving emergency PCI with IABP support were retrospectively reviewed, and 47 patients receiving emergency PCI without IABP support at the same time were included as the control group. Left ventricular function was evaluated in the 2 groups at 2 weeks and at 3 months after the operation respectively. The incidence of MACE was compared between the 2 groups at 30 days and also at 3 months after the operation. Results Patients receiving IABP support had greater improvement in left ventricular function at 2-week and 3-month after operation (43.8?8.2% vs 39.4?5.9%, 45.5?6.6 vs 40.6?4.6%, both P

Recently,the relationship between psoriasis and coronary heart disease(CHD)have been casting close attention.It has been demonstrated that the prevalence of CHD in patients with psoriasis is more than one time higher than that of healthy people. Meanwhile,the prevalences of hypertension,diabetes mellitus, hyperlipoidemia and smoking in patients with psoriasis are higher than those of normal people,and some drugs for treatment of psoriasis may induce CHD.Therefore,the relationship between psoriasis and CHD is still unclear.In this paper,two cases of psoriasis complicated with CHD are reported,and the relationship between psoriasis and CHD is explored.

Objective To investigate laparoscopic-guided selective portal vein ligation in the two-stage hepatectomy for patients with primary hepatocellular carcinoma (HCC).Methods Twenty-three patients with HCC who were not suitable for one-stage hepatectomy were admitted to the Sichuan Provincial People's Hospital from March 2009 to February 2012.Their clinical data were retrospectively analyzed.Laparoscopic-guided selective portal vein ligation was firstly performed,dynamic changes of hepatic volume and predicted volume of liver to be resected were detected by computed tomography.Two-stage open hepatectomy was performed after assessment of resectability of HCC.All data were analyzed using the analysis of variance or q test.Results Laparoscopic-guided selective portal vein ligation was successfully performed on 22 patients (2 patients received concomitant cholecystectomy because the right branch of portal vein was difficult to expose),1 patient was converted to open surgery because of hemorrhage during portal vein separation.Three patients with multiple lesions received transcatheter arterial chemoembolization at 1 week after selective portal vein ligation.Dull pain in the hepatic region,low fever,nausea and vomiting were observed in the 23 patients,while no severe complications including peritoneal hemorrhage,bile leakage,hepatapostema was observed.The levels of aspartate aminotransferase,alanine aminotransferase and total bilirubin were back to normal at 1 week after the surgery.The right liver volume at postoperative week 3 was (590 ± 154)cm3,which was significantly smaller than (698 ± 135)cm3 before surgery.Compared with right liver volume at postoperative week 1,2,3,the right liver volume before operation was significantly smaller (F=15.62,P ＜0.05).The left hepatic volume at postoperative week 3 was (408 ± 149)cm3,which was significantly bigger than (331 ± 68)cm3 before operation.The left liver volume before operation was significantly different from those at postoperative week 1,2,3 (F =17.48,P ＜ 0.05).The predicted ratio of liver to be resected was 60％ ± 18％ at postoperative week 3,which was significantly smaller than 67％ ± 15％ before operation (F =12.35,P ＜ 0.05).Two patients with insufficient hyperplasia of offside liver,2 patients with intrahepatic metastasis at postoperative week 3,2 patients were lost to follow up and 3 patients gave up hepatectomy,14 patients received hepatectomy at 2-4 weeks after laparoscopic-guided selective portal vein ligation.The resection rate was 60.9％ (14/23).There were 2 patients received extended right hepatectomy,8 received right hepatectomy,4 received non-anatomical hepatectomy.All the 14 patients recovered well,and no hepatic failure,severe peritoneal effusion and infection was observed.Conclusion Laparoscopic-guided selective portal vein ligation is easy to perform,and it extends the indication of hepatectomy,increases the safety of two-stage hepatectomy.

Objective To detect the micrometastasis status and necessity of dissection of lymph nodes of hepatodudenal ligament in advanced gastric antral cancer. Methods Eighty-six lymph node samples of hepatodudenal ligament which were negative in routine pathological examinations were collected from 45 gastric antral cancer patients with radical dissection.The expressions of CK20 mRNA were detected for the existence of micrometastasis by RT-PCR. Results Micrometastasis was found in 46 out of 86 lymph nodes(53.49%) and 23 out of 45 patients(51.11%),significantly different from the routine pathological examinations(both P

AlM:To determine the changes of regional macular retinal thickness ( RT ) with spectral domain optical coherence tomography ( SD-OCT ) after successful pars plana vitrectomy ( PPV ) surgery with inner limiting membrane ( lLM ) peeling in patients with idiopathic macular hole.
METHODS:A non-randomized retrospective case study on 17 patients ( 17 eyes ) who were hospitalized between March 1, 2011 and June 30, 2013. All 17 eyes had been diagnosed with idiopathic macular hole and thereafter underwent 25G-PPV surgeries performed by the same surgeon with lLM peeling and short - term gas tamponade. ln the 6mo-plus follow-up after surgery, these eyes were found to have successful closure in the macular hole. The macular RT of the nine areas in the Early Treatment Diabetic Retinopathy Study was measured by SD-OCT. All patients were applied by SD-OCT with linear scan of the macular. At least four examinations on the operated eye were conducted in contrast to the other normal eye: before the surgery, 3~5wk after the surgery (stage A), 2~3mo after the surgery (stage B), and >6mo after the surgery (stage C).
RESULTS:ln stage A, the macular RT of operated eyes in the areas of C, lS, ll, lN, OS, Ol, ON (263. 00±39. 48, 313. 92±18. 35, 311. 00±18. 02, 335. 67±19. 91, 280. 83±33. 74, 269. 92 ± 23. 32, 307. 00 ± 28. 40 ) were significantly thicker than the corresponding areas of the normal fellow eyes (220. 51 ± 23. 94, 292. 08 ± 21. 93, 282. 50 ± 20. 30, 288. 33 ± 20. 76, 251. 25±17. 60, 247. 75±21. 48, 265. 17±24. 76ü m) (P<0. 01) with the exception of the lT (291. 58±18. 97, 280. 33± 20.82üm) and OT (250.83±21.21, 242.08±24.02üm) (P>0. 01). ln Stage B, the macular RT in the areas of ll, lN, OS (335.67±19.20,319.75±19.20, 273.50±16.89üm) were significantly thicker than the corresponding areas of the normal fellow eyes (286. 33±20. 46, 293. 42±17. 64, 252. 50± 16.32üm) (P<0. 01). However, the macular RT of the operated eyes in the areas of C, lS, lT, Ol and OT had no statistically significant difference compared with the corresponding areas of the normal fellow eyes (P> 0. 01). ln Stage C, the macular RT of operated eyes with the areas of lN (321. 17 ± 19. 71ü m) were significantly thicker than the corresponding areas of the normal fellow eyes (296.25±19.57üm) (P<0.01). Meanwhile the other areas of the operated eyes were not significantly different from the normal fellow eyes (P>0. 01). Moreover, the macular RT of operated eyes in the areas of ON, lT (307. 00±28. 40, 291. 58 ± 18. 97ü m ) in stage A significantly decreased compared to that of the corresponding areas in stage C (276. 08±32. 39, 278. 75±10. 19ü m) (P<0. 01).
CONCLUSlON: SD-OCT is a convenient tool for the observation of macular regional changes after macular hole surgery. Macular RT had persistent changes after vitrectomy on eyes with macular hole by SD-OCT. lLM peeling may have caused microstructural changes in wide areas of the macular region after PPV surgery. More support and evidence were provided to the further study of the long - term observation for the structural and function of macular after macular hole surgery.

Objective: To develop a headspace gas chromatography ( HS-GC ) assay for simultaneous determination of dichloroacetic acid ( DCA ) and trichloroacetic acid ( TCA ) in urine. Methods: Urine samples (5 mL) were transferred to a 22 mL headspace bottle, added with 0.5 mL 10% sodium acetate solution , immediately sealed, and shaken evenly. The bottle was placed in the HS-GC system, and equilibrated at 90 ℃ for 60 minutes. The mixture was separated with the HP-INNOWAX chromatographic column, and the DCA and TCA concentrations were detected with the hydrogen flame detector. Results: Under the optimal experimental conditions, the correlation coefficient of DCA and TAC was both > 0.999 0 within the range of 10-500.0 μg/L, and the lowest detection limits of DCA and TAC were 2.0 and 3.5 μg/L, with the spike recovery rate of 87.40% to 101.44%, and relative standard deviations of 1.89% to 3.25%. Of the 35 urine samples sampled from occupational populations, DCA and TCA were not detected. Conclusions The establishment of the HS-GAS assay through addition of sodium acetate and optimization of the headspace conditions, has high recovery and precision, which is effective to meet the requirements for daily determination of DCA and TCA in urine samples.

ObjectiveTo evaluate gallbladder conserving gallstone removal and polyps resection using combination laparoscopy,hard gallbladder endoscopy and soft choledochoscopy.MethodsClinical data of 122 patients with cholecystolithiasis or polyps undergoing removal of calculus (polyps) and preservation of gallbladder were analyzed retrospectively.ResultsGallstones in 56 patients and polyps in 24 cases was removed or resected successfully by laparoscopy and hard gallbladder endoscopy; In the remaining 34 cases stones were completely removed by combination soft choledochoscopy; 8 cases were converted to laparoscopic cholecystectomy.Romoved stone was single in 25 cases and multiple in 65 cases,with the number ranging from 1to 52,the diameter of stone ranged from 0.2 cm to 3.2 cm.In the 24 gallbladder polyps,7 cases were single,17 cases were multiple,the diameter of polyp ranged from 0.8cm to 1.2 cm.The operation time was 40-125 (78) min. The mean hospitalization was 4 days. No intraoperative and postoperative complications occurred.All patients were followed up for 1year.Gallstones recurred in 3 cases,and the recurrence rate was 3.06％. ConclusionsLaparoscopy combined with hard gallbladder endoscopy and soft choledochoscopy for removing calculi (polyp) and conserving gallbladder is safe and feasible.

Objective To compare the effects of higher dosage of atorvastatin alone and combination of lower dosage of atorvastatin with ezetimibe on levels of lipid and metalloproteinases in patients with coronary artery disease. Methods Forty-two patients with coronary artery stenosis (50% to 70% stenosis) without stent replacement were selected, and were randomly divided into atorvastatin group (treated with 20 mg or 40 mg atorvastatin alone, n = 19) and combined-therapy group(treated with 5 mg, 10 mg atorvastatin and 10 mg ezetimibe, n =23). The levels of serum lipid, hepatic and renal functions, creatine kinase, metalloproteinase (MMP)-2, MMP-9 and tissue inhibitor of MMP-1 (TIMP-1) were detected 12 weeks after treatment. Results Twelve weeks after treatment, the level of LDL-C in atorvastain group was (1.94 ± 0.49) mmol/L (37.82% decrease from baseline), and that in combined-therapy group was (1.92 ±0.54) mmol/L(38. 26% decrease from baseline), and there was no significant difference between these two groups (P >0.05). Twelve weeks after treatment, the levels of MMP-2 and MMP-9 were significantly decreased and that of TIMP-1 was significantly increased compared with baseline levels in atorvastatin, while no such changes were detected in combined-therapy group. Conclusion In patients with coronary artery stenosis, combined therapy with lower dosage of atorvastatin and ezetimibe may lead to the same lipid-lowing effects compared with therapy with higher dosage of atorvastatin, but it may not result in a significant reduction in serum levels of MMP-2, MMP-9 and increase of TIMP-1.
