Objective To investigate the safety,efficacy and effects of emergent percutaneous coronary intervention (PCI) in patients from Second Affiliated Hospital,Medical College,Zhejiang University with cardiogenic shock (CS) complicating acute myocardial infarction (AMI).Method Twenty-seven patients with CS complicating with AMI were treated by PCI with intraaortic balloon counterpulsation (IABP) support.The change of hemodynamics before and after IABP and PCI,the characteristics of PCI,the mortality during hospitalization, the major adverse cardiac events (MACE) and left ventricular ejection fraction at 30-day follow-up were observed.Results The hemodynamics were significantly improved after IABP.No patients died during PCI.Two patients died after PCI and the total mortality was 7.4% in hospital.During the period of 30-day follow-up, one patient died of heart failure.The left ventricular ejection fraction greatly improved at 30 days after PCI. Conclusions The data suggested that the use of IABP during PCI in patients with CS complicating AMI was safe, decreased mortality and improved prognosis.

Background and purpose:The occurrence and development of lung cancer are closely correlated with the immune function in the human body.The patients with malignant tumors have shown a disorder of immune function,especially in terms of loss of cellular immune function.The purpose of this study was to investigate the possible auxiliary effect of sipulin in the treatment of advanced non-small-cell lung cancer(NSCLC).methods: Ninety-three patients were randomly divided into two groups:sipulin group:sipulin plus docetaxel+cisplatin;control group:only administered docetaxel+cisplatin.The leukocyte,haemoglobin and platelet,toxicity of digestive tract,body weight,Karnofsky status and efficacy of those patients were evaluated before and after therapy,respectively.Results: Overall response rates were 46.67% and 30.23%(P=0.023)in sipulin group and control group,respectively.The median survival time was 10.1months versus 8.3 months(P=0.035)in sipulin group and control group,respectively.The 1-year survival rate for sipulin group and control group was 52.9% versus 39.4%(P=0.038),respectively.The clinical efficacy and the frequence of leukocyte reduction were better in sipulin group than in control group,the quality of life and clinical symptom of the patients in sipulin group were improved more significantly than those in control group (P

Objective: To obtain polycystin-1 intracellular region. Methods: cDNA of polycystin-1 intracellular region was generated by PCR and then cloned into pProEX Hta, which was prokaryotic expression vector. After verified by sequencing, the recombinant was transformed into E.coli host to express and purify the fusion protein by affinity chromatography. Results: 660 bp cDNA of polycystin-1 intracellular region and 2.6×104 fusion protein were obtained. Conclusion: The fusion protein containing polycystin-1 intracellular region is obtained and is helpful for preparing anti-polycystin-1 monoclonal antibody.

Objective To compare the diagnostic value of renal ultrasound scan (RUS) and 99Tcmdimercaptosuccinic acid (DMSA) renal scintigraphy in children with acute pyelonephritis (APN). Methods In all, 165 children with initial clinical diagnosis of APN, aged from 1.5 months to 11 yrs ( median 20 months), were included in the study, all of which were examined with RUS and DMSA renal scientigraphy. The diagnosis with DMSA renal scientigraphy results was taken as the standard reference to evaluate the diagnostic sensitivity and specificity of RUS. Results Of 99 out of all 330 kidneys that were found abnormal on DMSA renal scientigraphy, 31 were abnormal on RUS. Of the rest normal kidneys on DMSA scans renal scientigraphy, 4 were abnormal on RUS. Thus diagnostic sensitivity of RUS for APN was 31.3%(31/99) and specificity was 98.3% (227/231). Conclusions Although RUS provides with high diagnostic specificity for children with APN, its low sensitivity may underestimate the clinical evaluation of APN.More often than not, 99Tcm-DMSA renal scientigraphy is a clinical necesscity for the definite RUS diagnosis.

Objective To evaluate the intervention effects of low-fluoride brick tea in the population, and to provide data for the prevention and control of the brick-tea type fluorosis. Methods Eighty-six Kazakh families with 5-12 years old children were selected and divided into two groups in the severe brick-tea type fluorosis areas of Akesai County of Gansu Province. Forty-six households were intervened by drinking low-fluoride brick tea as intervention group and another 40 households drank general brick tea as control group. The fluoride content in water, tea and urine was monitored and the total daily fluoride intake of adults and children was calculated by the fluoride content of the tea before and during intervention. The baseline prevalence of dental fluorosis was surveyed in all Kazakh school students aged 5 - 12 years before intervention, dental fluorosis prevalence were surveyed in two groups after the intervention. The fluoride content in water, urine,tea, and brick-tea samples was detected by iron electrode method, and dental fluorosis was diagnosed by Dean's method. Results The fluoride content of water were 0.36,0.50 mg/L respectively before and 42 months after intervention. The total daily fluoride intake of adults and children in the intervention group (being 4.39,5.12,5.38,4.49 mg in adults and 1.90,2.33 in children, 2.33, 1.94 mg for four calculations) were lower than those in control group (8.42,9.07,8.35,7.92 and 3.65,3.93, 3.62,3.43 mg). Except the second batch (530.4 mg/kg), the average fluoride content of the other 3 batches of low-fluoride brick tea(239.3,222.88,154.7 mg/kg) was lower than that of 4 batches of market brick tea(366.9,412.2, 286.0,379.6 mg/kg). The fluoride content of low-fluoride brick tea samples was in accordance with the national standard(< 300 mg/kg) in 16 of 21 samples in 4 the batches, and the qualifying rate was 76.19%(16/21). Only 5 of 21 market brick tea samples in 4 batches was qualified, accounting for 23.80%(5/21), both were significantly different(χ2= 11.52, P < 0.01). In 12, 36, 42 months after intervention, urine fluoride content in the intervention group of adult(1.84,1.23,1.77 mg/L) and children(1.55,0.65,1.10 mg/L) was less than that of the control group (adults: 3.37,3.68,3.02 mg/L, children: 2.64,1.64,2.62 mg/L), both being statistically significant (t value were 2.94,2.43,3.91,3.29,2.31,4.42, P < 0.01 or 0.05). The detective rate of dental fluorosis was 69.02%(127/184)at baseline among children. After the intervention, it lowered to [44.83% (13/29) in the intervention group, significantly lower than that in the control group[71.88%(23/32), χ2 = 4.60, P < 0.05]. Conclusion Low-fluoride brick tea can reduce the fluoride intake of the residents who drink brick tea, and alleviate excessive fluoride and the damage of high-fluoride.

?AlM:To observe the eye complications in the cases of acute chlorine gas poisoning.
?METHODS:A retrospective review of 121 cases of acute chlorine gas poising with eye irritation, dry eye and other eye complications in Linyi People’s Hospital from February 2009 to February 2013 was performed.
?RESULTS: Among 121 patients, 117 cases ( about 96. 7%) had complications of eye irritation and conjunctival and corneal epithelial damage, and the ocular surface damage was aggravated with the increasing level of chlorine gas poisoning. After 3, 6mo being discharged, 32 and 7 patients respectively occurred dry eye among 115 patients followed up. One mild chlorine poisoning patient, during the hormonotherapy of pulmonary complication, complicated with bullous retinal detachment, of which symptoms and physical signs had been improved after stopping hormonotherapy and adding drugs facilitating fluid absorption. One severe chlorine poisoning patient with loss of consciousness during the treatment, had corneal ulcer and after ulcer being healed with drug and conjunctival flap covering surgery, was left permanent leukoma cornea.
?CONCLUSlON: Acute chlorine poisoning can cause corneal and conjunctival epithelial damage and dry eye. Ocular complications like bullous retinal detachment associated with hormone application should be paid more attention to in the hormonotherapy. For some patients with severe poisoning, the therapy of corneal and conjunctival epitheliums should be taken seriously in case of irreparable damage in rescuing patient’s life.
