Objective To explore the effect of eletroacupuncture (EA) on angiogenesis after cerebral ischemia and reperfusion through observing the number of peripheral blood endothelial progenitor cells (EPCs) and the expression of vascular endothelial growth factor (VEGF) in the hippocampus.Methods Among 50 male Sprague-Dawley (SD) rats,10 were randomly selected as a control group (CG).Qi deficiency and blood stasis were induced in the other 40 rats by intragastric administration of dahuang daily for 7 days.A model of focal cerebral ischemia and reperfusion injury was then created by thread-occlusion of the middle cerebral artery,except in 10 rats selected for the sham operation group (SOG) who received the same operation without tightening the thread.The successfully modeled rats were divided into a model group (MG,n =10) and an electroacupuncture group (EAG,n =10).The rats in EAG started acupuncture treatment the next day after modeling,while no treatment was given to those in the other groups.On day 1,3 and 7 after the modeling,the neurological functioning of the 4 groups was assessed using Basso-Beattie-Bresnahan locomotion scoring and the number of EPCs in the peripheral circulation was detected by flow cytometry.On the 8th day,all the rats were decapitated and the VEGF expression was detected immunohistochemically.Results The average BBB locomotion score of the EAG rose significantly from (4.50 ± 1.05) on day 1,to (13.67 ± 1.21) on day 3,and then further to (20.00 ±0.89) by day 7,significantly higher than that of MG at the same time points,but still significantly lower than that of the control group.The average number of EPCs in the peripheral circulation in the MG also increased from (26.83 ± 6.05) on day 1 to (33.67 ± 5.39) on day 3,and decreased to (32.83 ± 5.04) on day 7 after modeling,significantly lower than that of the CG [(45.50 ±9.40),(42.17 ±4.62) and (41.33 ±5.50)],the SOG [(58.00 ±8.05),(59.67±4.84) and (53.83 ±5.38)[and the EAG [(66.17 ±4.36),(127.50 ±73.75) and (55.00 ±35.15)] at each time point.After occlusion,the average expression of VEGF-positive cells in the hippocampus of the EAG [(27.80 ± 2.39)%] was significantly higher than that of the MG,and both were significantly higher than that of the CG.Conclusions Eletroacupuncture can up-regulate VEGF expression and EPCs in the peripheral blood in rats after cerebral ischemia-reperfusion,which can promote angiogenesis and neural functional recovery.

OBJECTIVETo explore an ideal surgical method for nipple hypertrophy correction.
METHODSFrom July 2008 to June 2011, 44 nipple reductions were performed for 22 women (44 sides) by using the modified Z-shaped incision technique. The incision consists of two circles, one quadrangle and one triangle located on the top, body and base of the nipple. The nipple's height was decreased and the nipple diameter and base area were reduced. Bilateral nipples were designed symmetrically.
RESULTS22 cases(44 sides) were treated with primary healing. The mean diameter of the nipple was reduced to (9.8 +/- 1.6) mm from (17.6 +/- 3.4) mm, the average height from (18.8 +/- 3.6) mm to (8.2 +/- 1.4) mm, with the patient supine. All the patients were followed up for 14 months to 4 years with satisfactory results. No nipple necrosis, infection and numb happened. 20 patients completed the self-designed survey scale 1 year after operation, of which 4 cases achieved normal lactation, and the remaining patients didn't have childbirth and breastfeeding yet.
CONCLUSIONSThe modified Z-shaped incision technique could reduce the height, diameter, and most importantly, reduce the basal shape of all types of hypertrophic nipple to create a desired new cylindrical nipple without affection of nipple sensation and function.

Objective To explore the relationship between the four different molecular subtypes of locally advanced breast cancer(LABC) and the clinical effect of neoadjuvant chemotherapy containing docetaxel and anthracyclines on breast cancer. Methods The record of 68 patients with LABC who were treated with the therapeutic scheme was reviewed. Breast cancer molecules were diagnosed by core needle biopsy through IHC and were divided into four subtypes. After 3 to 5 courses of treatment, the relationship of molecular subtype and clinical effects was analyzed. Results Univariate analysis showed that absence of estrogen receptor (ER) expression and size of tumor (≤5cm) were predictive factors for clinical complete response (cCR) (P<0.05).Over expression of HER-2 and molecular subtypes were predictive for pathologic complete response (pCR) (P<0.05). pCR rate of HER2+/ER- subtype in this therapeutic scheme was, higher than that of other subtypes and pCR rate of Luminal A subtype was the lowest. Multivariate analysis showed that molecular subtypes cant be the predictive factors for this therapeutic scheme (P>0.05) and only HER-2 (P<0.05) was the independent variable in predicting pCR for this therapeutic scheme. Conclusion Molecular subtypes can not independently predict pCR for neoadjuvant chemotherapy regimen containing docetaxel and anthracyclines.

OBJECTIVE To explore mecha-nisms of imperatorin on regulating P-glycoprotein(P-gp)in blood-brain barrier(BBB)based on net-work pharmacology combined with in vitro experi-ment.METHODS Drug targets were predicted using the Pharmapper and Swiss targets data-bases;disease targets were obtained through the Genecards database;intersections between drugs and disease targets were screened by Cytoscape software;the obtained core targets were used to construct protein-protein interaction(PPI)network,gene ontology(GO)functions,and Kyoto encyclopedia of genes and genomes(KEGG)pathway enrichment analysis.The effects of imperatorin(20,50,100 μ mol·L-1)on P-gp activity were monitored in hCMEC/D3in vitro BBB model,and the effects of imperatorin on the expression of target proteins were verified using Western blot method.RESULTS 55 drug targets and 3102 disease targets were obtained from the network pharmacology screening,and 37 core targets were obtained after the combination.Enrichment analysis showed that core targets were closely related to chemical synaptic trans-mission regulation,neurotransmitter receptor activity,proteinkinaseregulationactivity,G protein-coupled receptor signaling pathway,neural active ligand receptor interaction pathway,PI3K-Akt sig-naling pathway,VEGF signaling pathway,etc..In vitro experimental validation suggested that all tested concentration groups of imperatorin signifi-cantly reduced the activity and expression of P-gp,which were achieved by significantly downregu-lating the phosphorylation levels of PI3K and Akt,and repressing the expression of VEGFR2 pro-tein.CONCLUSION Network pharmacology was used to predict the core targets and signaling pathways of imperatorin on regulating P-gp in BBB and relevant validation was conducted through in vitro experiments,providing a refer-ence basis for further exploration of the mecha-nisms of imperatorin on regulating P-gp in BBB.

Objective:To compare the detection and amplitude of epileptiform discharges (EDs) between surface sphenoidal electrode and anterior temporal electrode in patients with interictal EDs in the temporal region, and to explore the value of surface sphenoidal electrode.Methods:A total of 1 356 outpatients with epilepsy who underwent 2-hour video electroencephalogram (EEG) monitoring in Xuanwu Hospital from October to December 2021 were retrospectively enrolled. All patients were hooked up with scalp electrode according to the international 10-20 system as well as surface sphenoidal electrode and anterior temporal electrode. The EEGs with EDs recorded by surface sphenoidal electrode and/or anterior temporal electrode were selected for analysis. The detection rate and the amplitude of EDs by surface sphenoidal electrode and anterior temporal electrode were compared.Results:Seventy-three EEGs were collected and 250 EDs were counted. The detection rate of the anterior temporal electrode and surface sphenoidal electrode were 88.0% (220/250) and 98.4% (246/250) respectively. The difference in detection rate was statistically significant (χ 2=18.38, P<0.001). For the EDs from anterior temporal regions (taking the discharges recorded by anterior temporal electrode as "gold standard"), the detection rate of surface sphenoidal electrode was 98.2% (216/220). There was no statistically significant difference in detection rate between the anterior temporal electrode and surface sphenoidal electrode (χ 2=2.27, P=0.132). There were 216 EDs recorded by these two kinds of electrode simultaneously. The average amplitude of the EDs on surface sphenoidal electrode and anterior temporal electrode was (77.1±38.9) μV and (80.2±44.9) μV, respectively. The difference was statistically significant ( t=2.28, P=0.031). Conclusions:The detection rate of surface sphenoid electrodes was higher than that of anterior temporal electrodes for the EDs in the temporal region, and surface sphenoidal electrodes can be used routinely in outpatient. The surface sphenoidal electrode had more chance to detect EDs originating from regions out of the anterior temporal regions.

Objective To compare the the levels of serum adipose factors and glucagon like peptide-1 (GLP-1) in patients with stable coronary artery disease ( SCAD ) and different body mass index (BMI). Methods From August 2011 to December 2013, seventy-nine patients with stable coronary artery disease (SCAD,n=79) undergone coronary angiography and controls with matched age and sex (n=80) in Beijing Anzhen Hospital, Capital Medical University with stable coronary heart disease with normal body mass and obesity confirmed by coronary angiography (CAG) were selected,and eighty non CHD patients confirmed by age and sex matched by CAG were selected as the control group. According to the body mass index ( BMI) and the diagnosis of coronary heart disease,the subjects were divided into normal group (n=40,BMI=18. 5-24 kg/m2), obesity group (n=40,weight≥28 kg/m2),SCAD group (n=39) and obesity SCAD group (n=39). The levels of TNF-α,HMW-APN,Irisin,FGF-21,GLP-1,Apelin were measured by enzyme-linked immuno sorbent assay (ELISA). Results The serum GLP-1 and HMW-APN level of obesity participants was (18. 50±5. 27)ng/L, (3. 85±1. 59) mg/L,much lower than those in non-obesity participants ((20. 35±5. 5)ng/L,( 4. 57±2. 01) mg/L( P<0. 05). The serum GLP-1 level of obesity SCAD group ((17. 59±5. 13)ng/L) was also lower than that in SCAD group ((21. 21±5. 06) mg/L) (P<0. 05). The level of FGF-21 was negatively correlated with fasting blood glucose (r=-0. 169,P<0. 05). Conclusion The decrease of GLP-1 level was associated with obesity and stable coronary heart disease. Irisin,FGF-21 and Apelin were found to have no predictive value for obese patients with stable coronary heart disease

Objective:
We used polysomnography (PSG) monitoring and neuropsychological scales to explore the characteristics of coronavirus disease-2019 (COVID-19) patients diagnosed with post-traumatic stress disorder (PTSD) in Wuhan, two years after the onset of the COVID-19 pandemic.
Methods:
A total of 42 patients in the Sleep Medicine Center were diagnosed with insomnia between December 2021 and May 2022; they were divided into the PTSD group (patients with PTSD diagnosed with insomnia after COVID-19 infection) and the non-PTSD group (patients with insomnia without PTSD). A healthy control group was simultaneously included.
Results:
The PTSD group was more significant than the non-PTSD group in partial manifestations of sleep disorders, neuropsychological clinical symptoms, and partial PSG data. Patients with different COVID-19 subtypes showed significant differences in the course of disease, sleep disorders, neuropsychological clinical symptoms, relevant scale scores, and PSG data analysis.
Conclusion
The emotional anxiety and depression of COVID-19 patients diagnosed with PTSD two years after the COVID-19 pandemic in Wuhan are more significant, and will not be self-alleviated with the passage of time. It is necessary to continue to pay attention to the PTSD symptoms and sleep psychology of COVID-19 infected patients, and take appropriate measures. Patients with severe and critical COVID-19 have more severe sleep and mental disorders, and there is a significant correlation between the duration of the disease and the severity of mental and mental disorders and sleep disorders after recovery.

Objective To investigate the changes of prevalence of hyperuricemia ( HUA) and its correlations with blood glucose and lipid in healthy adults receiving physical examination at Peking Union Medical College Hospital (PUMCH) from 2012 to 2017. Meth-ods An observational approach was adopted for the data analysis.The test results of uric acid (UA),fasting blood glucose (FBG),to-tal cholesterol (TC),triacylglycerol (TG),low density lipoprotein cholesterol (LDL-C),high density lipoprotein cholesterol (HDL-C), creatinine (Cr) and Urea of 399 089 cases (206 881 males and 192 208 females) at PUMCH from January 2012 to December 2017 were collected and statistically analyzed.Results The total prevalence of HUA was 17.4% in which the prevalence of males was signif-icantly higher than that of females (25.6% vs 8.5%,χ2=20 234.850,P<0.01).During the years of 2012 to 2017,the prevalence of HUA was 26.5%,24.7%,28.6%,23.9%,24.8% and 24.5% in males,and 13.8%,6.3%,7.9%,6.1%,6.2% and 6.8% in females for each year respectively.The prevalence of HUA in males aged 18 to 64 years old was significantly higher than that in the age-matched fe-males (all P<0.05).However, the prevalence of HUA in males aged≥65 years old was similar to the age-matched females.There was no statistically significant difference of HUA prevalence between males and females aged ≥65 in 2013,2015,2016 and 2017 ( χ2=1.792,0.017,1.440 and 0.205 respectively;all P>0.05).The percentages of hyperlipidemia in both males and females of HUA group were higher than those of non-HUA group respectively (all P<0.01).The percentage of hyperglycemia in males of non-HUA group was higher than that of HUA group,but the percentage of hyperglycemia in females of non-HUA group was lower than that of HUA group ( all P<0.01).High levels of TC,TG and FBG were risk factors of HUA with increased OR values in increased concentrations of TC,TG and FBG,respectively.Conclusion During the recent 6 years, in healthy adults receiving physiced examination at PVMCH, the preva-lence of male HUA diagnosed was at overall high level,but the prevalence of female HUA was in decreasing and relatively stable trend. Hyperlipidemia and hyperglycemia should be the risk factors of HUA.
