The experiment was performed on neurons freshly isolated from rat DRG by using whole cell patch clamp techniques. When 60 cells responded to GABA were treated with SKF38393, a selective agonist of dopamine Dl receptor, it was found that except one cell which exhibited a slight potentiation( l0.0%,l/60), the inhibition by SKF38393 of GABA-activated current was predominant (88.33%,53/60), while the remainders were of no effect( l.66%,6/60). In 50 neurons tested , when the neurons were treated with R(-)-NPA prior to the application of GABA for 30sec, It was found that GABA-activated membrane currents were inhibited (76%,38/50) , enhanced (2%,l/50) , no effected markedly (22%,11/50). The effect of SKF38393 and R(-)-NPA was dependent on the concentration of SKF38393 and R(-)-NPA . By intracellular application of 10-4mol/L H7, a potent inhibitor of protein kinase , via micropipette the inhibition of SKF38393 and R(-)-NPA was abolished apparently as compared with the control .

Background Postoperative ametropia, especially large astigmatism after deep anterior lamellar keratoplasty (DALK) for keratoconus often results in poor visual acuity.Though postoperative ametropia can be corrected by wearing glasses or performing corneal refractive surgery, the visual quality of patients is still poor, and the operations are difficult to implement because of insufficient corneal thickness.Toric intraocular collamer lens (TICL) implantation appears to have good corrective efficacy on severe astigmatism,but the research on the eyes after DALK is still less.Objective This study was to evaluate the efficacy and safety of TICL implantation for the ametropic eyes following DALK for keratoconus.Methods This study protocol was approved by Ethic Commission of Nanjing Drum Tower Hospital,and written informed consent was obtained from each patient prior to any medical procedure.A self-controlled serial observational research was carried out.Eight ametropic eyes of 8 patients who received the DALK for keratoconus before 18 months were enrolled in Nanjing Drum Tower Hospital from August 201 1 to March 2012, with the spherical diopter range from 0 D to-7.5 D and cylindrical diopter range from-2.5 D to-6.0 D.TICL implantation was performed on the eyes.The eye examinations were carried out before surgery and 1 week,3 months,6 months, 1 year and 2 years after surgery,including uncorrected visual acuity (UCVA) ,best corrected visual acuity (BCVA) ,comprehensive optometry, corneal astigmatism degree, the central corneal thickness and anterior chamber depth (ACD), corneal endothelial cell counts (ECD) ,intraocular pressure.The examination outcomes were compared before and after surgery.The intraoperative and postoperative complications were observed to evaluate the safety of TICL implantation for the ametropic eyes following DALK for keratoconus.Results The UCVA and BCVA were obviously improved at 6 months after TICL implantation in comparison with before surgery and maintained stable during the follow-up duration.The mean spherical diopter was from-0.5 D to-1.0 D and the mean cylindrical diopter was from-0.5 D to-2.0 D after surgery.The corneal endothelial cell counts were (2 520.2 ± 307.2) , (2 496.2 ± 306.2) , (2 469.6±304.5) , (2 432.0 ± 305.4), (2 383.4 ± 309.4)/mm2, and the intraoeular pressures were (14.57 ± 3.75), (16.62±4.21), (16.57±3.56), (15.66±3.37), (15.13±3.48) mmHg, showing insignificant differences among different time points (F =0.375,P =0.825;F =9.871, P =0.394).No significant differences were found in mean ACD and intraocular pressure between before and after surgery (t =1.56 ,P =0.16).The axial deviation of TICL was less than 10° in all the operated eyes 6 months after surgery.No intraoperative and postoperative complications were found during the follow-up duration.Conclusions TICL implantation is a safe and effective alternative and viable approach to myopic and astigmatism patients following DALK for keratoconus.

Objective To investigate the predictive value of the non-invasive indicator deceleration capacity of heart rate (DC) in the sudden cardiac death (SCD) after acute myocardial infarction. Methods A total of 417 myocardial infarc?tion patients with ST-segment elevation in sinus rhythm were enrolled in this study. DC was assessed from data of 24-hour ECG Holter. Regular follow-ups were carried out within 12 months. The SCD events were recorded and compared with pa?tients without SCD. Results During 12 months of follow-up, 20 patients were died due to SCD (4.8%). Compared with sur?vival group, patients showed significantly lower left ventricular ejection fraction (LVEF, 0.393 ± 0.065 vs 0.528 ± 0.042, P<0.05) and DC [(2.85±1.66) ms vs (5.49±1.71) ms,P<0.05]in SCD group. Multivariate Cox proportional hazard regression analysis showed that lower LVEF(<0.35)[RR: 2.167(1.384-4.661), P=0.013]and DC (DC<4.5 ms)[RR: 3.706(2.709-5.374),P=0.020]were risk factors for the occurrence of SCD. The prediction sensitivity by the decreased LVEF and DC was 52.1%and 76.4%respectively, and the specificity was 84.5%and 86.1%respectively. Conclusion The decreased value of DC after acute myocardial infarction can predict the SCD events.

Objective To investigate clinical therapeutic effects after a series of improvements of multi-site combination in the simple obese patient with tumescent liposuction. Methods Before tumescence anesthetization, short-acting benzo-diazepine was used as sedative inducer. The pressure and fluid velocity of short-acting benzodiazepine were regulated and injected into deeper level of fat at first, and all of these actions decreased the pain of patients, and promote the effect of the pain tolerance. The positions of the incisions were selected to hide from view and specifically protected, which could improve looks and decrease the scar formation after operation. In later stage of operation the flaps were pressurized and slid from outside, in order to make the flaps even and smooth and to keep their thickness according to the position of the flaps and the age of the patients. Opened draining was changed to block draining after operation. Results 73 cases were taken the follow-up for 6~24 months. All cases obtained satisfactory results, except that one cases was complicated by scar hypertrophy. The changes of the circumferences were as follows: the decrease of the maximum circumference of thigh was from 2 cm to 17cm, abdomen from 3 cm to 24 cm, and buttocks from 1 cm to 3 cm. Conclusions A series of improvement of key measures enhance the clinical therapeutic effects of multi-site combination in the simple obese patient with tumescent liposuction.

Objective To explore the activity of daily living in patients with schizophrenia and its related factors. Methods 200 patientswith schizophrenia were investigated with the questionnaire about general condition, the Positive and Negative Syndrome Scale (PANSS)and Activity of Daily Living Scale (ADL) when hospitalized. The relationship between the scores of ADL and sexuality, age, education level,marital status, profession before the disease attacking, household, disease type, course of the disease, frequency of attacking and hospitalizationor scores of PANSS was analyzed. Results The score of ADL was significantly above the normal level (t=32.206, P=0.000) in theschizophrenics. The score of ADL was not significantly different among the patients in different gender, education level, marital status, profession,household and the frequency of hospitalization (P>0.05), but was significantly different among the ages (F=3.851, P=0.023) and diseasetype (F=19.793, P=0.000). The score of ADL positively correlated with the course of the disease (r=0.161, P=0.023), frequency of attacking(r=0.396, P=0.000) and the difference value between the numbers of attacking and hospitalization (r=0.425, P=0.000), so as the totaland each factors scores of PANSS (P=0.000), but did not correlated with frequency of hospitalization (r= 0.097, P=0.174). By multiple regressionanalysis, only 3 factors score of PANSS, the frequency of attacking and the difference value between the numbers of attacking andhospitalization entered into the regression equation (F=53.630, P=0.000). Conclusion The patients with schizophrenia generally fall in activityof daily living. The more serious the disease, the more frequent the attacking and the more the difference value between the numbers ofattacking and hospitalization, the poorer the activity of daily living was.
