To summarize the clinical experience of Professor LIU Jinmin in treatment for epilepsy. It is believed that main pathogenesis of epilepsy is yangming failure to close and vital activity loss control， so a therapeutic approach focused on restoring the closure of yangming and regaining vital activity was proposed for the treatment of epilepsy. For excess syndrome， the treatment focuses on draining excess and descending qi， promoting purgation and restoring spirit. When yangming dryness-heat predominates， the approach involves unblock the bowels and regulating the spirit， descending qi and reducing fire， with modified Chengqi Decoction （承气汤） as prescription； when yangming phlegm-fire predominates， the treatment focuses on clearing heat and resolving phlegm， calming mind and suppressing fright， with modified Qingxin Wendan Decoction （清心温胆汤） as prescription； when yangming blood stasis predominates， the approach involves breaking up blood stasis and promoting purgation， eliminating stasis and awakening the mind， with Taoren Chengqi Decoction （桃核承气汤） as prescription. For deficiency syndrome， the treatment emphasizes tonifying deficiency and raising qi， strengthening the stomach and nourishing the spirit. When center qi deficiency and sinking of clear qi of the nutrients from food， the approach involves replenishing and uplifting qi while nourishing vital activity， with modified Liujunzi Decoction （六君子汤） as prescription； when yin deficiency and fluid consumption， the treatment focuses on nourishing stomach and tonifying yin， promoting fluid production and calming the spirit， with modified Maimendong Decoction （麦门冬汤） combined with Yiwei Decoction （益胃汤） as prescriptions. In clinical situations of deficiency-excess complex， it is essential to distinguish the primary condition from the secondary， applying both supplementing and draining methods flexibly to achieve optimal treatment.

Objective:To analyze the bubble dynamic characteristics of shock wave enhanced emission photoacoustic streaming(SWEEPS)technique in free water region under different temporay delays.Methods:The Er∶YAG laser tip was activated in free water model with SWEEPS mode at 150-600 μs pulse delay.The bubble dynamic process during irrigation was recorded by a high-speed camera(200 000 Hz).Matlab was used to analyze the interaction between bubble made by the dual pulses frame by frame.The distance between bubble remnants and laser tip was measured before the bubble disappeared.The experimental data were statisti-cally analyzed by SPSS 19.0.Results:In free water region,different temporal delays caused different interaction between the bub-bles activated by the SWEEPS technique with a dual pulse modality.The interactions include bubble fusion,bubble collision and bubble separation.When the temporal delay between 360-440 μs,bubble collision was the most violent,and the farthest distance between bubble remnants and laser tip was reached.Conclusion:In free water region,the dual pulse of SWEEPS technique can lead to bubble interaction which may enhance the cavitation effect of Er∶YAG laser irrigation,and improve the debridement in clinic ap-plication.

Objective To investigate the clinical efficacy of Kangfuxin solution combined with lidocaine and gentamicin in the treatment of oral ulcers. Method A total of 120 patients with oral ulcer admitted to Tongzhou District Maternity and Child Health Care Hospital of Beijing from May 2019 to July 2021 were selected and divided into observation group and control group randomly. 58 patients were treated with lidocaine as a control group and 62 patients in the observation group were treated with Kangfuxin solution combined with lidocaine and gentamicin. The clinical efficacy, including oral ulcer condition, visual analogue scale (VAS score) after 3d and 5d of treatment, inflammatory factor levels and adverse reactions were observed and compared between the two groups before and after treatment. Results The overall effective rate of the treatment group (95.12%) was higher than that of the control group (74.36%) and the difference was statistically significant (P<0.05). The ulcer area, ulcer healing time, and chewing improvement period were remarkably reduced compared with those in the control group (P<0.05). The VAS scores after 3d and 5d of treatment, the levels of tumor necrosis factor-α (TNF-α), C-reactive protein (CRP) and interleukin-6 (IL-6) between the two groups were statistically significant (P<0.05). There was no significant difference in the incidence of adverse reactions (3.22%) between the observation group and the control group (6.90%) (P>0.05). Conclusion Kangfuxin solution combined with lidocaine and gentamicin showed better curative effect on oral ulcer. This treatment regimen could effectively ameliorate various clinical symptoms of patients with oral ulcer, reduce patient pain and downregulate the levels of inflammatory factors, and help patients recover with high safety profile.

There were statistically significant differences in MMN( Fz, F4) amplitude (before-intervention: (-0.98±0.19)μV, (-0.96±0.19)μV; after-intervention: (-1.38±0.16)μV, (-1.17±0.19)μV)before and after intervention in the intervention group (both P<0.05), but there was no significant difference in MMN(F3) amplitude(before-intervention: (-0.90±0.28)μV; after-intervention: (-1.01±0.59)μV)before and after intervention in the intervention group ( P>0.05), and there were statistically significant differences in MMN(F3, Fz, F4) latency (before-intervention: (184.16±33.07)ms, (179.20±25.35)ms, (184.95±28.22)ms; after-intervention: (177.38±26.45)ms, (172.17±23.87)ms, (179.84±23.60)ms)before and after intervention in the intervention group(all P<0.05). After pseudo-stimulation, there were no statistically significant differences in MMN( F3, Fz, F4) amplitude(before-intervention: (-0.92±0.21)μV, (-0.89±0.20)μV, (-0.94±0.16)μV; after-intervention: (-0.80±0.50)μV, (-0.91±0.17)μV, (-0.99±0.16)μV)and latency (before-intervention: (184.91±26.96)ms, (180.99±25.29)ms, (181.55±23.19)ms; after-intervention: (182.08±24.95)ms, (177.94±21.30)ms, (179.18±21.62)ms) before and after intervention in the control group (all P>0.05). Conclusion:After repeated transcranial magnetic stimulation, the pre-attentive processing of the intervention group is improved, which shows that bilateral simultaneous stimulation of the rTMS program is effective.

Objective:To investigate the association of blood oxidative stress level with hypertriglyceridemia in the elderly aged 65 years and older in China.Methods:A total of 2 393 participants aged 65 years and older were recruited in 9 longevity areas from Heathy Aging and Biomarkers Cohort Study, during 2017 to 2018. Information on demographics characteristic, life style and health status were collected by questionnaire and physical examination, and venous blood was collected to detect the levels of blood oxidative stress and hypertriglyceridemia. The linear or non-linear association between oxidative stress and hypertriglyceridemia was described by restrictive cubic splines (RCS) fitting multiple linear regression model. The generalized linear mixed effect model was conducted to assess the association between oxidative stress and hypertriglyceridemia.Results:A total of 2 393 participants, mean age was 84.6 years, the youngest was 65 and the oldest was 112, the male was 47.9%(1 145/2 393), the triglyceride level was (1.4±0.8) mmol/L. The hypertriglyceridemia detection rate was 9.99%(239/2 393). The results of multiple linear regression model with restrictive cubic spline fitting showed that MDA level was linear association with triglyceride level; SOD level was nonlinear association with triglyceride level. MDA level had significantly association with hypertriglyceridemia, and the corresponding OR value was 1.063 (95% CI: 1.046,1.081) with 1 nmol/ml increment of blood MDA; SOD level had significantly association with hypertriglyceridemia, and the corresponding OR value was 0.986(95% CI: 0.983,0.989) with 1 U/ml increment of blood SOD. Conclusion:Among the elderly aged 65 and older in 9 longevity areas in China, MDA and SOD levels were associated with the risk of hypertriglyceridemia.

Objective:To investigate the association between blood lead concentrations and cognition impairment among Chinese older adults aged 65 or over.Method:Data was collected in 9 longevity areas from Heathy Aging and Biomarkers Cohort Study between 2017 and 2018. This study included 1 684 elderly aged 65 years and older. Information about demographic characteristics, socioeconomic factors, health status and cognitive function score of respondents were collected by questionnaire survey and physical examination. Venous blood of the subjects was collected to detect the blood lead concentration. Subjects were stratified into four groups ( Q 1- Q 4) by quartile of blood lead concentration. Multivariate logistic regression model was used to analyze the association between blood lead concentration and cognitive impairment. The linear or non-linear association between blood lead concentration and cognitive impairment were described by restrictive cubic splines (RCS). Results:Among the 1 684 respondents, 843 (50.1%) were female and 191 (11.3%) suffered from cognition impairment. After adjusting for confounding factors, the OR value and 95% CI of cognition impairment was 1.05 (1.01-1.10) for every 10 μg/L increase in blood lead concentration in elderly; Compared with the elderly in Q 1, the elderly with higher blood lead concentration had an increased risk of cognitive impairment. The OR value and 95% CIof Q2, Q3 and Q4 groups were 1.19 (0.69-2.05), 1.45 (0.84-2.51) and 1.92 (1.13-3.27), respectively. Conclusion:Higher blood lead concentration is associated with cognitive impairment among the elderly aged 65 years and older in 9 longevity areas in China.

Objective:To investigate the impact of diabetes mellitus (DM) and stroke on long-term outcomes in patients with acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI).Methods:Total 411 consecutive ACS patients undergoing PCI at the Ninth People′s Hospital of Zhengzhou between December 2014 and June 2018 were recruited, including 319 males and 92 females with a mean age of (64.7±10.1) years. These patients were divided into 4 groups according to the presence or absence of history of diabetes or stroke: non-DM non-stroke group ( n=192) , DM group ( n=140), stroke group ( n=41), and DM+stroke group ( n=38). The data of baseline demographic characteristics, clinical feature, coronary angiographic findings, and cardiovascular adverse events during long-term follow-up were obtained. Kaplan-Meier curves were used to investigate the long-term clinical outcomes among groups. Results:The mean interval of follow-up was (24.1±13.8) months. Patients with DM+stroke had the highest rates of non-fetal myocardial infarction (χ 2=24.932) , non-fetal stroke (χ 2=9.434) , hospitalization due to heart failure/angina (χ 2=69.290) , revascularization (χ 2=22.918) , cardiovascular death(χ 2=13.473)and all-cause death(χ 2=17.724)as well as hard endpoint events (the sum of non-fetal myocardial infarction, non-fetal stroke, and all-cause death) (χ 2=30.268)and combined major adverse cardiovascular events (MACE) (the sum of hard endpoint events, hospitalization due to heart failure/angina, and revascularization) (χ 2=119.556)among 4 groups(all P<0.01). In Kaplan-Meier survival analysis, the cumulative ratio of freedom from all-cause death decreased significantly in DM+stroke group compared with no DM no stroke group ( HR=17.121, 95 %CI: 2.527-115.934, P<0.01), but no statistical difference was observed in the cumulative ratio of freedom from all-cause death between DM+stroke group and DM group or stroke group respectively ( HR=3.178, 95 %CI: 0.744-13.582; HR=1.383, 95 %CI: 0.374-5.118; all P>0.05) . Meanwhile, patients with DM+stroke presented significantly lower cumulated ratio free from combined MACE than patients with non-DM non-stroke ( HR=5.423, 95 %CI:2.941-10.036, P<0.01), and the cumulated ratio free from combined MACE also decreased significantly in DM+stroke group as compared to DM group or stroke group respectively ( HR=1.859,95 %CI: 1.167-2.962; HR=1.991,95 %CI: 1.178-3.364; all P<0.01) . Conclusions:ACS patients with combined history of DM and stroke have a worse long-term outcomes after PCI than those with DM alone or stroke alone or without DM or stroke. DM and stroke seemed to have an additive effect on decrease in the cumulative ratio free from combined MACE in ACS patients following PCI.
