Objective:To investigate the cognitive functions of temporal lobe epilepsy (TLE) patients with bilateral asynchronous interictal discharges.Methods:A total of 162 TLE patients who were treated at Zhongshan Hospital, Fudan University, from June 2021 to December 2023 were collected. According to the interictal scalp electroencephalogram, TLE patients were classified to the TLE with bilateral temporal asynchronous interictal epileptiform discharges ( n=51) and TLE with unilateral temporal epileptiform discharges ( n=111). Unilateral TLE patients were divided into TLE with right ( n=48) and left ( n=63) temporal epileptiform discharges. The Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment (MoCA), Digital Span (DS), Verbal Fluency Test (VFT), the third part of Color Word Test (CWT-C), Trail Making Test-B (TMT-B), Symbol Digit Modalities Test (SDMT), Auditory Verbal Learning Test (AVLT), Rey-Osterrieth Complex Figure (ROCF), and Similarity Comprehension Test were performed for the participants. The differences of cognitive functions between patients with bilateral and unilateral temporal discharges were compared. Univariate and multivariate Logistic regression models were used to analyze the risk factors for patients with bilateral temporal asynchronous discharges. Spearman analysis was used to explore the correlation between cognitive function and clinical indicators. Results:In the group of TLE patients with bilateral asynchronous discharges compared to those with unilateral discharges, the completion time of CWT-C [67 (55, 103) s vs 59 (50, 71) s, Z=-2.904, P=0.004], TMT-B [159 (108, 219) s vs 129 (95, 180) s, Z=-2.361, P=0.018] was longer. Additionally, TLE patients with bilateral asynchronous discharges got lower scores of MMSE [28 (26, 29) vs 29 (28, 30), Z=3.098, P=0.002], MoCA [23 (19, 28) vs 27 (23, 28), Z=3.175, P=0.001], AVLT1+2+3 [16.843±6.482 vs 19.162±5.526, t=-2.347, P=0.020], AVLT6 [6 (3, 10) vs 8 (5, 10), Z=3.275, P=0.001], ROCF2 [15 (8, 22) vs 20 (12, 25), Z=2.870, P=0.004], ROCF3 [14 (8, 22) vs 20 (11, 25), Z=2.634, P=0.008], and Similarity Test [13 (8, 18) vs 16 (12, 20), Z=2.387, P=0.017] as well as lower VFT-vegetable and fruit count [15 (13, 19) vs 18 (15, 21), Z=2.402, P=0.016] and SDMT completion count [41 (30, 53) vs 51 (40, 60), Z=3.089, P=0.002]. The multivariate Logistic regression analysis showed that the decrease in AVLT6 scores ( OR=1.546, 95% CI 1.150-2.078, P=0.004) and longer TMT-B time ( OR=1.013, 95% CI 1.001-1.025, P=0.035) were independent risk factors for TLE patients with bilateral asynchronous discharges. Conclusions:Compared to the patients with TLE characterized by unilateral temporal lobe discharges, those with asynchronous discharges in bilateral temporal lobes show statistically significant declines in all domains of cognitive functions, including executive function, memory, and language abilities. Decreased cue recall ability in language memory and prolonged trail-making test in executive function are independent cognitive impairment risk factors for bilateral temporal asynchronous discharges.

Background At present, a large number of reports focus on the bones of limbs and trunk, while there are few studies on the effect of fluorosis on jawbone which is the inevitable structural basis for the development and treatment of oral diseases. Objective To preliminarily investigate the effect of fluoride exposure on the mechanical properties of jawbone by observing the changes in the intraosseous environment and the maximum load against shearing force (LSF_max) of the jawbone in rats with chronic fluoride treatment. Methods Screening experiment: 48 SD male rats were randomly divided into a control group and three fluoride exposure groups (50, 150, and 250 mg·L⁻¹ fluoride concentration), 12 rats in each group. The fluoride exposure groups were molded by feeding different concentrations of sodium fluoride solution, and the control group drank tap water from Guizhou area. Each group was further divided into 4 subgroups with 3 animals each according to observation time points after 0, 2, 4, and 6 months. The LSF_max of the jawbone was measured with an electronic universal ergometer, the expression of type I collagen (Col1) was shown by Sirius red staining, and the expression of runt-related transcription factor 2 (Runx2) was determined semi-quantitatively by immunohistochemistry at selected time points. Formal experiment: 12 male SD rats were randomly divided into a fluoride exposure group and a control group. The fluoride exposure group were fed with 150 mg·L⁻¹ sodium fluoride solution, and the control group drank tap water from Guizhou. After feeding with fluoride for 5 months, the ergometer was used to measure the LSF_max of the jawbone. Osteoclasts were counted after tartrate resistant acid phosphatase (TRAP) staining. Col1, Runx2, bone morphogenetic protein 2 (BMP-2), alkaline phosphatase (ALP), and cathepsin K (Cath K) were detected semi-quantitatively by immunohistochemistry expression and Sirius red staining. Micro computed tomography (Micro CT) was used to observe the trabecular bone microstructure. Results Screening experiment: The LSF_max of the control group and the 50 mg·L⁻¹ fluoride exposure group reached the peak value at the 2nd month, and the LSF_max of the 50 mg·L⁻¹ fluoride exposure group reached the valley value at the 4th month. The LSF_max of the 150 mg·L⁻¹ fluoride exposure group at the 4th month was higher than that at the 6th month (P<0.05). There was no significant difference in the LSF_max at each time point in the 250 mg·L⁻¹ fluoride exposure group. At the same time point, there was no statistically significant difference in LSF_max among the groups. The Col1 levels of the 50 mg·L⁻¹, 150 mg·L⁻¹, and 250 mg·L⁻¹ fluoride exposure groups were higher than the time point 0 from the 2nd month (P＜0.05). The Runx2 showed no statistically significant difference by concentration or time. Formal experiment: After feeding with 150 mg·L⁻¹ fluoride for 5 months, the LSF_max of the fluoride exposure group was greater than that of the control group (P<0.05). The expressions of Col1, Runx2, BMP2, ALP, and Cath K in the fluorosis exposure group were higher than those in the control group (P<0.05). There were no statistically significant differences in osteoclast count or indicators of bone trabecular microstructure. Conclusion Chronic fluoride exposure may increase the shear strength of jaw bone.

Anti-seizure medications (ASMs) are the main therapy for epilepsy.There are many kinds of ASMs with complex mechanism of action, so it is difficult for pharmacists to examine prescriptions.This paper put forward some suggestions on the indications, dosage forms/routes of administration, appropriateness of usage and dosage, combined medication and drug interaction, long-term prescription review, individual differences in pathophysiology of children, and drug selection when complicated with common epilepsy, for the reference of doctors and pharmacists.

Objective Based on hemodynamic analysis, to investigate the cause of distal re-entry tear in Stanford type B aortic dissection after thoracic endovascular aortic repair (TEVAR).Methods A patient with type B aortic dissection was reexamined regularly with computed tomography angiography (CTA) at 1st month, 6th month, 12th month and 24th month after TEVAR. Based on the CTA images in each period, three-dimensional (3D) aorta models were reconstructed to perform morphological analysis and hemodynamic simulation.Results Compared with the diameter at 1st month after TEVAR, the diameter of true lumen at 12 months after TEVAR increased by 1.8 times and the global distortion of aorta increased by 16.67%. At postoperative 1st, 6th and 12th month, the maximum blood velocities at the new entry tear in systole were 69.6%, 33.7% and 92.1% higher than the average ones at distal landing zone, and the maximum wall shear stresses (WSSs) were 2.52, 2.32 and 3.52 times of the average WSSs respectively. In addition, the maximum time-averaged WSS (TAWSS) at 1st, 6th and 12th month after TEVAR were 1.88, 2.53 and 3.62 times of the mean TAWSS respectively.ConclusionsThe morphology of the aorta remodeled after TEVAR, and a sudden change in the diameter of true lumen occurred at distal anchoring zone and continued to increase. As a result, the blood flow velocity in this area accelerated, and the intima was continuously exposed to high WSS, leading to the redissection.

Objective:To analyze the clinical effects of the pre-expanded internal mammary artery perforator flap in large chest keloids surgical treatment.Methods:Patients with large chest keloid were treated with the pre-expanded internal mammary artery perforator flap between January 2017 and September 2021. The surgical treatment was divided into two different phases. In the first phase, a tissue expander was implanted beneath the skin within the angiosome of the internal mammary artery perforator. The expander was injected with normal saline once a week. In the second phase, the expander and the keloid tissue were removed, and a pre-expanded internal mammary artery perforator flap was designed to cover the wound. Radiotherapy and hyperbaric oxygen therapy were performed in the postoperative period. The treatment effect was followed up. The postoperative complications were analyzed, and the recurrence and patient satisfaction rates were recorded.Results:A total of 41 patients were enrolled, including 20 male and 21 female patients. The patients’ age ranged from 24 to 64, with a mean disease history of 11.9 years. The mean size of the keloid was 9 cm × 8 cm. Some patients were treated with one expander, but four expanders were needed in some extensive cases. The volume of the expander ranged from 80 to 600 ml. The mean volume was 300 ml, with a mean expansion time of 3 months. The mean flap size was 9 cm × 8 cm. Two cases with distal necrosis were observed. Five cases suffered from partial incision scar hyperplasia. No recurrence occurred during the followed-up period. Thirty-six patients (87.8%) were satisfied with the operation effect, and five (12.2%) thought the effect was acceptable.Conclusions:The pre-expanded internal mammary artery perforator flap is an effective treatment for the large chest keloid. It can provide sufficient skin tissue for wound repair, with a stable blood supply and an excellent curative effect.

Objective:To explore the clinical features and survival of newly diagnosed follicular lymphoma (FL) patients with diffuse large B-cell lymphoma (DLBCL) component.Methods:1845 newly diagnosed FL patients aged ≥ 18 years with grades 1-3a in 11 medical centers in China from 2000 to 2020 were included, and patients with DLBCL component were screened. The clinical data and survival data of the patients were retrospectively analyzed, and the prognostic factors were screened by univariate and multivariate analysis.Results:146 patients (7.9% ) with newly diagnosed FL had DLBCL component. The median age was 56 (25-83) years, 79 males (54.1% ) . The pathology of 127 patients showed the proportion of DLBCL component. Patients were divided into two groups according to whether the proportion of DLBCL component was ≥ 50% . The study found that patients with DLBCL component ≥ 50% had higher grade 3 ratio (94.3% vs 91.9% , P=0.010) , Ki-67 index ≥ 70% ratio (58.5% vs 32.9% , P=0.013) and PET-CT SUVmax ≥ 13 ratio (72.4% vs 46.3% , P=0.030) than patients with DLBCL component<50% . All patients received CHOP or CHOP like ± rituximab chemotherapy. The overall response rate (ORR) was 88.2% , and the complete response (CR) rate was 76.4% . In the groups with different proportions of DLBCL component, there was no significant difference in the remission rate after induction treatment and the incidence of disease progression within 2 years after initiation of treatment (POD24) ( P<0.05) . The overall estimated 5-year progression free survival (PFS) rate was 58.9% , and the 5-year overall survival (OS) rate was 90.4% . The 5-year OS rate of POD24 patients was lower than that of non POD24 patients (70.3% vs 98.5% , P<0.001) . Compared with non maintenance treatment of rituximab, maintenance treatment of rituximab could not benefit the 5-year PFS rate (57.7% vs 58.8% , P=0.543) , and the 5-year OS rate had a benefit trend, but the difference was not statistically significant (100% vs 87.8% , P=0.082) . Multivariate analysis showed that failure to reach CR after induction treatment was an independent risk factor for PFS ( P=0.006) , while LDH higher than normal was an independent risk factor for OS ( P=0.031) . Conclusion:FL patients with DLBCL component ≥50% have more invasive clinical and pathological features. CHOP/CHOP like ± rituximab regimen can improve the clinical efficacy of patients. Rituximab maintenance therapy can not benefit the PFS and OS of patients. Failure to reach CR after induction therapy was the independent unfavorable factor for PFS.

Objective:To compare the difference of epileptiform discharges detection in patients with epilepsy between the 25 electrodes electroencephalogram (EEG) system proposed by the International Federation of Clinical Neurophysiology in 2017 and the previous 19 electrodes EEG system.Methods:Patients suspected of epilepsy or with confirmed epilepsy who need a follow-up EEG were collected in Zhongshan Hospital, Fudan University from March 2018 to November 2019, and conventional video-EEG recording was performed on all patients for two hours with the standard 25 electrodes EEG system. Two neurophysiologists reviewed the recordings blindly using the 19 electrodes system and the 25 electrodes system, marking the epileptiform discharges and their amplitudes. Finally, the data were statistically analyzed.Results:A total of 403 patients were included in the study, in which 263 cases were diagnosed as epilepsy, including 129 cases of generalized epilepsy, 115 cases of temporal lobe epilepsy, 13 cases of frontal lobe epilepsy, two cases of parietal lobe epilepsy and four cases of occipital lobe epilepsy. In 115 temporal lobe epilepsy patients, 76 (66.09%) and 100 (86.96%) records were detected epileptiform discharges by the 19 or 25 electrodes EEG system respectively, and the difference was statistically significant (χ2=13.939, P<0.001). While in patients with non-temporal lobe epilepsy, there was not statistically significant difference between the two systems. In 76 patients whose temporal epileptiform discharges were detected by the two systems, the amplitudes of epileptiform discharges in the newly-added inferior temporal electrodes (F9/F10, T9/T10, P9/P10) and the original temporal electrodes (F7/F8, T7/T8, P7/P8) were (61.53±22.64) μV and (48.25±20.90) μV, respectively, with statistically significant difference between the two groups ( t=5.486, P<0.001). In patients with abnormal [79.59% (39/49) vs 61.22% (30/49), χ2=3.967, P=0.046] and normal [95.45% (42/44) vs 70.45% (31/44), χ2=9.724, P=0.003] imaging, the ability of the 25 electrodes EEG system to detect epileptiform discharges was higher than that of the 19 electrodes EEG system. Conclusion:The 25 electrodes EEG system can significantly improve the detection ability of temporal epileptiform discharges in patients with epilepsy, which is recommended for regular use to increase the detection ability of temporal area abnormal wave and assist the diagnosis and treatment of epilepsy.

Objective:To explore the correlation between the level of heart rate deceleration (DC), serum homocysteine(Hcy), the scope and extent of coronary artery lesion in coronary heart disease patients with hypertension.Methods:From January 2019 to October 2019, 103 coronary heart disease patients with hypertension who were diagnosed and hospitalized in cardiovascular department of Binzhou Central Hospital were selected as coronary heart disease(CHD) group, and 52 patients with simple hypertension were selected as control group.The serum Hcy levels of the two groups were measured and analyzed.The DC value and the difference of the two groups were analyzed.The degree of coronary artery lesion was evaluated by the number of coronary artery lesion and Gensini score.The relationship between DC, Hcy and the degree of coronary artery lesion was analyzed.Results:Compared with the control group, the DC value of CHD group was significantly lower [(6.02±1.97)ms vs.(4.97±1.59)ms, t=-3.989, P<0.05], and the serum Hcy level was increased [(11.46±4.38)μmol/L vs.(16.79±6.31)μmol/L, t=4.260, P<0.05]. In the CHD group, the DC values and Gensini scores of the patients with single vessel lesion, double vessel lesions and three vessel lesions were (5.52±1.34)ms, (5.06±1.29)ms, (4.39±1.19)ms, (21.35±17.10)points, (26.93±18.18)points, (49.39±30.14)points, respectively.The DC value of patients with three vessel lesions was lower than that of patients with single vessel lesion( F=7.349, P<0.05), and the Gensini score was higher( F=13.487, P<0.05). There were no statistically significant differences in DC value and Gensini score between patients with three vessel lesions and those with two vessel lesions and those with single vessel lesion( P>0.05). The serum Hcy levels of patients with single, double and three vessel lesions were (14.67±5.97)μmol/L, (15.85±6.29)μmol/L and (16.97±7.13)μmol/L, respectively.The difference among the three groups was statistically significant ( F=12.427, P<0.05). There was a negative correlation between DC and Gensini score( r=-0.310, P<0.05), and a positive correlation between serum Hcy and Gensini score( r=0.369, P<0.05). Conclusion:The DC value and Hcy level in coronary heart disease patients with hypertension are significantly decreased, which are closely related to the degree of coronary artery lesion.

Objective:To know the work status of clinical pharmacy in medical institutions of Guizhou province. Methods:Ques-tionnaires were used to analyze the situation of clinical pharmacy in 108 medical institutions of Guizhou province. Results: A total of 246 questionnaires were taken back, and among the 231 valid questionnaires were received including gradeⅡor above hospitals. The main contents of clinical pharmacy work carried out in medical institutions included 7 aspects: pharmacists ’ participation in ward rounds, which accounted for 47. 11%; pharmacists’ participation in case consultation, which accounted for 16. 65%; pharmacists’ participation in teaching practice, which accounted for 38. 84%; pharmacists’ participation in prescription evaluation and analysis, which accounted for 72. 73%;pharmacists’ participation in antimicrobial drug monitoring and drug use evaluation, which accounted for 62. 37%;pharmacists’ participation in drug counsultation and education, which accounted for 58. 68%;pharmacists’ participation in adverse drug reaction monitoring and supervision, which accounted for 77. 32%. Conclusion:The development of clinical pharmacy in Guizhou province still lags behind, and the number of clinical pharmacists is insufficient, which can’ t meet the growing demand for personalized medicine. In particular, the development of clinical pharmacy is restricted by the limited pharmaceutical service. The cog-nition degree of pharmacist group in Guizhou province has been improved. However, the number and the service quality of clinical pharmacists need to be improved further.
