Objective To evaluate the efficacy of neuronavigation-guided selective percutaneous radiofrequency aiming at the target point semilunar ganglion in the treatment of trigeminal neuralgia.Methods One hundred and forty-seven patients with primary trigeminal neuralgia of both sexes,aged 32-99 yr,with VAS score ≥ 8,were randomly divided into 2 groups:C-arm group (group C,n =72) and neuronavigation group (group N,n =72).Hartel anterior puncture was used and the C-arm guided puncture was performed at the target point foramen ovale in group C.In group N,three-dimensional reconstruction was made after the skull MRI images were transmired to the navigational system of StealthStation,and then the puncture path and point were designed after the target in the trigeminal ganglion was determined.The successful puncture and puncture-and radiofrequency-related complications were also recorded.The VAS scores were recorded at 1 and 7 days and 1,6,12 and 24 months after operation and the analgesic efficacy was evaluated.The therapeutic effect was evaluated by using Barrow Neurological Institute scoring system at 1 and 24 months after operation.Results No puncture-related side effects,damage to the oculomotor nerve or tinnitus developed in group N.The success rate of puncture at first attempt and the effective analgesia rate at different time points after operation were significantly higher,and the treatment effect was better in group N than in group C (P ＜ 0.05).There was no significant difference in the time for location of the nerve and incidence of facial numbness between the two groups (P ＞ 0.05).Conclusion Neuronavigation-guided selective percutaneous radiofrequency aiming at the target point semilunar ganglion in the treatment of trigeminal neuralgia provides a better efficacy,and a lower recurrence rate and a higher probability of successful puncture,with fewer complications.

Objective To investigate the effect of exercise on calcium modulin in myocardial sarcoplasmic re-ticulum of animal type 1 diabetes model in rat. Methods A total of 40 Spragne-Dawley rats were randomly dividedinto 4 groups : a normal control group, an exercise training group, a diabetes group and a diabetes plus exercise-traininggroup. At the end of 4- week-exercise training after the establishment of the diabetes model by intraperitoncal injectionof sterptozotocin, the animals were sacrificed and the level of blood glucose, insulin, blood fat and glycosylated serumprotein were tested. The gene expression of calcium modulin proteins was measured by reverse transcription-polymerasechain reaction, and the Western blotting technique was used to measure the protein of sarcoplasmic endoplasmic reticu-lure Ca<'2+> -ATPase (SERCA2) and phaspholamban (PLB). Results The level of biochemical indicator of exercisegroup is not affected when comparing with that of the control group, but significantly changed in diabetic group ( P <0. 01 ) ; The level of blood glucose, insulin, blood fat and glycosylated serum protein were ameliorated in diabetic rats inthe exercise training group. No significant changes in mRNA level of SERCA2, PLB and ryanodine receptor type 2(RYR2) were observed between control and diabetic group, the same to protein expression of SERCA2 and PLB. Butexpression of calcium modulin mRNA was significantly increased in exercise group and diabetic rats in the exercisetraining group comparing with that of the control and diabetic groups ( P < 0.01 ), the same to protein expression ofSERCA2 and PLB. Conclusion Exercise exerted good protective effects on the myocardial injury with 1 type diabetesrat, which might attribute to the upregnlated expression of SERCA2, PLB and RYR2 in diabetic rat heart.

Objective To evaluate the effects of sevoflurane-remifentanil anesthesia on the balance between cerebral oxygen supply and demand during cerebral revascularization for ischemic moyamoya disease by monitoring regional cerebral O2 saturation (rSO2) with near infrared spectroscopy.Methods Forty patients of both sexes aged 19-59 yr with a body mass index of 19-25 kg/m2 undergoing superficial temporal artery-middle cerebral artery anastomosis were randomly allocated into 2 groups (n =20 each):propofol-remifentanil group (group PR) and sevoflurane-remifentanil group (group SR).Radial artery was cannulated for direct BP monitoring and blood sampling.Near infrared spectroscopy probe was placed on the forehead.Anesthesia was induced with propofol TCI (Cp =5 μg/ml),fentanyl 3 μg/kg and rocuronium 0.6 mg/kg.The patients were mechanically ventilated after tracheal intubation (VT 8-10 ml/kg,RR 10-12 bpm,I∶ E 1∶2,FiO2 =1.0).PETCO2 was maintained at 35-40 mm Hg.Anesthesia was maintained with sevoflurane (end-tidal concentration 1.0％-1.7 ％) or propofol TCI (Cp =3-4 μg/ml) in combination with remifentanil TCI (Cp =3.5 ng/ml) and intermittent iv boluses of rocuronium 0.3 mg/kg.BIS was maintained at 40-60 during operation.rSO2 was recorded before induction of anesthesia (T0),10 min before and 10 min after blood vessel was clamped (T1,T2) and 10 min after anastomosis was completed (T3).Results rSO2 was significantly increased on the operated side at T3 in PR group while in SR group bilateral rSO2 was significantly increased at T1-3 as compared with the baseline values at T0 (P ＜ 0.05 or 0.01).rSO2 on the operated side was significantly higher at T1 in group SR than in PR group (P ＜ 0.05).Conclusion The efficacy of sevoflurane-remifentanil anesthesia is similar to that of propofol-remifentanil anesthesia for revascularization for moyamoya disease in terms of maintence of the balance between cerebral oxygen supply and demand.

Objective To observe the efficacy of Mimics finite element analysis software in the gasserian ganglion radiofrequency treatment of trigeminal neuralgia. Methods 180 cases with primary trigeminal neuralgia and VAS score ≥8 were randomly divided into 2 groups (n = 90 each): CT group (group C) and Mimics group (group M). The preoperative skull CT image of the foramen of cranial base could be analyzed in group C. The preoperative cranial CT image could be reconstructed and analyzed by Mimics finite element analysis software in group M. The puncturing success rate, complications rate and the outcomes between two groups were recorded. Results The puncturing success rates were 100% in group M and 92% in group C (P < 0.05). 6 cases with hematoma and 1 case, which were stabbed into the oral cavity were found in group C. No puncture complication was found in group G. There was no statistically significant between the two groups (P < 0.05). The VAS score was 1.6 ± 0.3 in group C and 1.3 ± 0.4 in group G, there was no statistical significance (P > 0.05) between them. Conclusions The Mimics finite element analysis software could improve the success rate of basicranial foramen ovale puncture and reduce the occurrence rate of puncture complications. Therefore , it could be safely applied to the treatment of primary trigeminal neuralgia by gasserian ganglion radio frequency.

Background lnterleuldn-18(IL- 18) plays a key role in the development,progression and outcome of coronary artery disease and its complications.However,its variability relation to the characterization of atherosclerotic plaque and percutaneous coronary intervention are still unknown.Methods Fifty four patients with coronary artery disease [22 patients with stable angina (SA) and 32 patients with acute coronary syndrome (ACS)] were enrolled in this study.All patients underwent percutaneous coronary intervention (PCI).The stability of the plaques at the criminal vessels was assessed with analogical IVUS.Serum IL-18 levels were measured at the time points of 5 rain before PCI,and Oh,6h,24h and lmonth after PCI in all patients.Results ACS group consisted mainly of lipidic unstable plaques while SA group of fibrous stable plaques.Moreover,compared with those in SA group,eccentricity index (EI) and remodeling index (RI) were significantly higher in ACS group.Positive remodeling was seen in ACS group while negative or no remodeling in SA group.Further,serum IL-18 levels were significantly elevated in patients with ACS than those in SA group before PCI,increased at Oh,6h,24h after PCI (P＜0.05)and were not significant different at 1 month after PCI from those before PCI.Conclusions There is significant difference in the composition and structural characteristics of atherosclerotic plaques between ACS and UA groups.PCI triggersd and enhances the inflammatory response in a short time.Serum levels of IL- 18 are the predictors of progression of unstable plaque in atherosclerosis.Post-operative complications of PCI might be reduced by inhibiting IL- 18.(J Geriatr Cardiol 2008;5:21-24)

Objective To explore the predictive value of ventricle late potential (LP) for arrhythmic events in the patients with Brugada syndrome. Methods Totally 43 patients with Brugada syndrome were divided into symptom group (n=24) and asymptom group (n=19).Signalaveraged electrocardiography(SAECG) was performed to analyze characteristics of LP in all subjects.The occurrence of arrhythmic events was observed in all patients during the dynamic follow-up for (33.8±9.0) months.Results There were 22 cases (91.7％) and 7 cases (36.8％) with LP positive in patients with symptom and asymptom,respectively.The incidences of arrhythmic events were 72.4％ in Brugada syndrome patients with positive LP and 14.3％ in patients with negative LP,respectively.The relative risk (RR,95％ CI) for LP prediction of the arrhythmic events was [5.1,(1.4～ 18.6)] (P =0.002). ConclusionsLP may be one of effective factors predicting arrhythmic events in the patients with Brugada syndrome.

To investigate the phenotypic characteristics of the strain of the rabies virus CTNCEC25, the strain of the China rabies virus CTN-1 adapted to primary chicken embryo cells (CECs), Vero cells, and mouse neuroblastoma N2a cells was inoculated with CTNCEC25 and parental CTN-1 strains to explore the cytopathic effect (CPE) and growth kinetics of CTNCEC25 on cultured cells. To determine the pathogenicity of CTNCEC25, suckling mice, adult mice, guinea pigs and rabbits were inoculated with CTNCEC25 via the intracerebral route and their survival monitored every day. Furthermore, the CTNCEC25 strain was passed serially in CECs for 20 passages and then 3 passages in the brains of suckling mice to determine phenotypic stability. CTNCEC25 achieved similar growth kinetics in Vero cells and N2a cells compared with parental CTN-1, but CTNCEC25 replicated more efficiently in CECs than the CTN-1 strain with a titer 72 h after infection reaching 10(7.5-7.6) FFU/mL, which was significantly higher than the 10(5.8) FFU/mL achieved by its parental strain, CTN-1. Moreover, CTNCEC25 induced apparent CPE in Vero cells, CECs and N2a cells. Analyses of intracerebral inoculation demonstrated that CTNCEC25 was attenuated profoundly in adult mice and was completely apathogenic to guinea pigs and rabbits, though it caused death in suckling mice. The CTNCEC25 strain proliferated steadily after serial passage in CECs and the brains of suckling mice, and remained avirulent in adult mice. These results suggest that CTNCEC25 is a highly attenuated and genetically stable strain of the rabies virus. CTNCEC25 replicated stably and efficiently in cultured cells and achieved high titers, so it could be a promising and safe vaccine strain for rabies prevention in China.

Objective:To compare the effects of paliperidone palmitate and olanzapine in the treatment of schizophrenia and its influence on the metabolism of patients.Methods:From February 2017 to February 2019, 86 patients with schizophrenia admitted to the Second People's Hospital of Taizhou were divided into observation group(43 cases) and control group(43 cases) according to random number table method.The observation group was injected paliperidone palmitate into deltoid muscle, while the control group was given olanzapine orally.Both two groups were treated for 12 weeks.The changes of PANSS and CGI scores, body mass, glucose metabolism, lipid metabolism and serum prolactin were compared between the two groups before and after treatment.Results:Before treatment, there were no statistically significant differences in the PANSS score, CGI score, body mass, glucose metabolism, lipid metabolism and serum prolactin between the two groups(all P>0.05). After treatment, the PANSS score and CGI score in the control group were (37.25±3.78)points and (2.51±0.36)points, respectively, which in the observation group were (37.28±4.35)points and (2.63±0.43)points, respectively, which were lower than before treatment(control group: t=29.010 and 11.817, observation group: t=36.257 and 13.503, all P<0.05), there were no statistically significant differences between the two groups(all P>0.05). After treatment, the body weight of the observation group was (62.18±3.56)kg, which was lower than that of the control group[(68.27±4.35)kg] ( t=7.105, P<0.05). After treatment, the fasting blood glucose(FBG) and HbA1c of the control group were (5.91±0.27)mmol/L, (8.94±0.78)%, respectively, which were higher than those of the observation group [(5.39±0.34)mmol/L and (7.65±0.63)%] ( t=7.854, 8.437, all P<0.05). The levels of TC, LDL-C and TG in the control group were (4.27±0.42)mmol/L, (3.27±0.43)mmol/L, (1.87±0.28)mmol/L, respectively, which in the observation group were (3.54±0.48)mmol/L, (2.56±0.54)mmol/L, (1.35±0.36)mmol/L, respectively, the differences were statistically significant between the two groups ( t=7.505, 6.745, 7.477, all P<0.05). After treatment, the serum level of prolactin of the control group was (84.35±12.41)μg/L, which was higher than that of the observation group [(59.87±9.53)μg/L]( t=10.259, P<0.05). Conclusion:Paliperidone palmitate is as effective as olanzapine in the treatment of schizophrenia, but it has little effect on body weight, glucose metabolism, lipid metabolism and prolactin level.
