Objective:To explore the therapeutic effect and safety of direct and selective percutaneous coronary inter-vention (PCI)in patients with ST elevation myocardial infarction (STEMI).Methods:A total of 138 STEMI pa-tients were randomly divided into direct PCI group (n=69,received PCI immediately after diagnosis)and selective PCI group (n=69,received acute thrombolysis therapy and then PCI in a selected time).Left ventricular ejection fraction (LVEF),peak creatine phosphokinase (CPK),CPK peak time,peak creatine kinase isoenzyme (CK-MB), CK-MB peak time,cardiac rupture rate during hospitalization,re-infarction rate and mortality rate within 30d and one year were compared between two groups.Results:Compared with selective PCI group after treatment,there were significant rise in LVEF [(49.3±6.8)% vs.(58.2±7.7)%],peak CPK [(74.9±49.3)IU/L vs.(113.0± 59.3)IU/L ]and peak CK-MB [(1983.1±1251.2)IU/L vs.(2588.6±1592.3)IU/L],and significant reduction in CPK peak time [(19.4±6.5)h vs.(13.9±4.5)h ]and CK-MB peak time [(19.7±7.7)h vs.(12.7±7.2) h]in direct PCI group,P <0.01 all;there were significant reductions in cardiac rupture rate (5.8% vs.0),re-in-farction rate (17.5% vs.6.3%)during hospitalization;mortality rates within 30d (11.0% vs.2.2%)and one year (22.2% vs.8.2%)in direct PCI group,P <0.05 all.Conclusion:Direct PCI in STEMI patients possesses better therapeutic effect and safety,which is worthy extending.

Objective To investigate the effects of prostaglandin E1 on proinflammatory and anti-inflammatory cytokines in sepsis patients.Methods One hundred and twenty cases of sepsis in ICU of our hospital were assigned to the groups:A,B,C and D,30 cases in each group.On the basis of conventional therapy,group A was added with prostaglandin El+ Xuebijing injection.The group was treated with prostaglandin E1,while the group C was treated with Xuebijing injection.The changes of APACHE Ⅱ score,Marshall score,anti-inflammatory and pro-inflammatory factors,mechanical ventilation time,ICU treatment time,28 d mortality rate in the 4 grups were observed and compared among 4 groups.Results The APACHE Ⅱ score and Marshall score after treatment in 4 groups were significantly decreased compared with before freatment (P＜0.05),Compared with the group B,C and D,The decrease of APACHE Ⅱ score,Marshace score,IL-1β,IL-6 and TNF-α levels was more significantly(P＜0.05),While the IL-10 level was significantly increastol(P＜0.05);duration of mechanical ventilation,length of stay ICU in were significantly shorter (P＜0.05),28 d mortality was significantly lower (P＜0.05).Conclusion Prostaglandin E1 combined with Xuebijing injection can effectively inhibit the inflammatory response in septic patients and promote the recovery of patients,reduces the mortality rate.

Objective To study the clinical value of combined detection of CA125 and CA153 for diagnosis of endometrial carcinoma.Methods The combimed detection of CA125 and CA153 were performed in 36 patients with endometrial carcinoma,confirmed by pathological examination,on admission and 2-3 months after operation.Fifty-seven patients with uterine myoma,admitted for laparotomy in the same period and confirmed by pathology,were as controls.Results The sensitivity of combined detection of CA125 and CA153 for diagnosing endometrial carcinoma increased to 82.3% and the specificity decreased.Total accuracy rate of diagnosis reached 75.1%.There was statistical difference between the group of endometrial carcinoma and controls(P

Fifty postoperative patients who suf- fered esophageal carcinoma were divided randomly into two groups.They received either enteral nutrition(Group EN,n=2 7) or parenteral nutrilion(Group PN,n=2 3) . The provisions of calorie and nitrogen were equal in the two groups.Nutrition support was started on the first postoperative day and continued for8days.The weight plas- ma proteins,immunological parameters and nitrogen balance were evaluated.The re- sults showed that there was no significant difference in body weight and serum albu- min level between the two groups.The pos- itive nitrogen balance were reached in both groups on the8th day.The CD4+percents age,the ratio of CD4+/ CD8+and NK cell activity were elevated,The conclusion is that the values of both EN and PN are sati- factory.In contrast with PN,EN has the advantages of physiological concordance and low cost.

OBJECTIVE: To investigate the changes and determine the difference of electrode impedance and neural response telemetry ( NRT) value with cochlear implants in children with malformed inner ear and normal inner ear. METHOD: Eighty-eight children with multi-channel cochlear implants participated in this study. Children were divided into malformed inner ear group and normal inner ear group. To test the electrode impedance values and NRT value. RESULT: The changes of electrode impedance showed the similar changing pattern in two groups. There was not different in electrode impedance values between the two groups (P > 0.05). The changes of electrode neural response telemetry values showed the similar changing pattern in two groups. There was significantly different in electrode impedance values between the two groups (P < 0.05). The NRT were going up higher from electrode 22 to electrode 1. CONCLUSION The values vary are different programming sessions and electrodes during the first 3 months of cochlear implant use. To acquire better hearing frequent programming sessions are necessary.

Objective To assess whether AECOPD patients can breathe independently at the PIC window and thus whether NPPV was necessary after extubation.Methods We performed a prospective observational study, we used the spontaneous breathing trial (SBT)to assess whether each patient could breathe independently at the PIC window,then performed extubation.Patients who passed the SBT received oxygen therapy only,whereas those who failed received NPPV.However,if the former showed respiratory distress,they also received NPPV.The primary out-come variables were SBT pass/fail,the demand for NPPV and rate of reintubation within 72h following extubation. Results In all,23 patients were enrolled,15cases(65.2%)of which passed the SBT.Of these,12cases (80.0%) patients developed respiratory distress after extubation and required NPPV (one of whom required reintubation).Of the eight patients that failed,one received reintubation after NPPV.The reintubation rates within 72h following extuba-tion of SBT-pass(7.0%)and SBT-fail (13.0%)(χ2 =1.476,P>0.05)patients were comparable.Conclusion Most AECOPD patients can breathe independently at the PIC window,but nonetheless develop respiratory distress and thus require NPPV following extubation.

Purpose: A kind of sine wave magnetic field generator with the extremely low frequency (ELF) is developed, the frequency and intensity of the magnetic field can be adjusted, and has been easily used in Bio-experimental study. Methods: At first ,we design a DC power supply which provide DC voltage to other chips,then the signal generated by single chip ma-chine system and the power amplifier combined by discrete components, it provides current 0 mA～136 mA.The current coil is designed by experiment's required,the size or turns is changed, the magnetic field intensity is changed too. Results: The fre-quency of the device output is 0 kHz-25 kHz with the intensity in the range of 0 mT～10 mT within which the continuous lin-earity is adjustable. Power sources are less than 30 W ,which can work for long.This device performs reliably and the measured values in accord with the theoretical values and has been used in the experiment of magnetic biological effect. Conclusions: The experiment results indicate that there exist the effects of ELF sine wave magnetic field upon potassium current of neurons, and that such bioeffects vary with the intensity and frequency of the field.Also,there may exist window effect areas.
