Objective:To investigate the clinical and electroencephalogram (EEG) characteristics of pattern-sensitive epilepsy (PSE).Methods:This retrospective case summary study enrolled 4 pediatric patients with PSE treated at the Peking University People′s Hospital from January 2015 to September 2023.The clinical data, EEG findings, treatments, and prognosis were retrospectively analyzed.Results:Among the 4 patients, 3 were female, and 2 had developmental delays before the onset of the disease.Spontaneous seizures occurred in 3 cases, including spasticity and tonic seizures in case 1, atypical absence seizures, myoclonic seizures, and general tonic-clonic seizures in case 3, and eyelid myoclonic seizures in case 4.All 4 cases exhibited pattern-induced reflex seizures, and pattern-induced seizures with photosensitivity were monitored by EEG in 3 cases.Of the 3 cases, 1 had myoclonic seizures, 1 had eyelid myoclonic seizures, and 1 had both myoclonic seizures and focal to bilateral tonic-clonic seizures.Two out of the 4 patients were diagnosed with epilepsy syndromes: Lennox-Gastaut syndrome and epilepsy with eyelid myoclonia.All 4 patients had interictal discharges, including 2 cases of generalized discharges, 1 case of multifocal discharges combined with generalized discharges, and 1 case of anterior head discharges.Three cases underwent the detection of whole exon gene and copy number variation, and 1 case showed a novel heterozygous mutation c. 73T>C(p.W25R) in the MBD5 gene on chromosome 2.Three patients were treated with antiseizure medication (ASM), while 1 did not receive ASM treatment because the seizures were all induced.However, none of the 4 had seizures under control after 5 to 10 years of follow-up. Conclusions:PSE is more common in female children and may co-occur with developmental delays and intellectual disabilities.In PSE children, the EEG shows mostly generalized discharges, spontaneous seizures, induced seizures, and predominantly generalized seizures coexist.Reflex seizures in PSE patients are more difficult to control with ASM treatment.

Excessive levels of cadmium (Cd) in soil exert serious negative impacts on soil ecosystems. Microorganisms are a common component of soil and show great potential for mitigating soil Cd. This review summarizes the application and remediation mechanisms of microorganisms, microbial-plants, and microbial-biochar in Cd-contaminated soil. Microorganisms such as Bacillus, Acinetobacter, Pseudomonas, and arbuscular mycorrhizal fungi (AMF) can change the biological validity of Cd through adsorption, mineralization, precipitation and dissolution. Different factors such as pH, temperature, biomass, concentration, and duration have significant effects on Cd bioavailability by microorganisms. Pseudomonas, Burkholderia, and Flavobacterium can promote the uptake of Cd²⁺ by hyperaccumulator through promotion and activation. Biochar, a soil amendment, possesses unique physicochemical properties and could act as a shelter for microorganisms in agriculture. The use of combined microbial-biochar can further stabilize Cd compared to using biochar alone.

Objective:To explore the clinical application of robot-assisted laparoscopic single-position nephroureterectomy and bladder sleeve resection for upper urinary tract urothelial carcinoma (UTUC).Methods:The clinicopathological data of 15 UTUC patients admitted to Union Hospital of Tongji Medical College of Huazhong University of Science and Technology from October 2018 to May 2020 were retrospectively analyzed. There were 8 males and 7 females, with a median age of 58.6 (ranging 52.6-69.6) years, including 8 cases of renal pelvic cancer, 2 cases of upper ureteral cancer, 5 cases of middle and lower ureteral cancer.The tumor located on the left side in 5 cases and right side in 10 cases. All 15 patients underwent robot-assisted one-step transperitoneal nephroureterectomy and bladder sleeve resection by the same surgeon. The patients were placed in a 70° healthy side lying position with a 10° head lower and foot high position. After routinely dissecting the kidneys and controlling the renal hilum, we continued to dissect the ureter down to the orifice of the bladder. The lymph node dissection was performed when dissecting the kidney and ureter. Then the ureter was resected like a sleeve and the bladder was sutured. Observation indicators, such as operation time, blood loss, postoperative drainage tube and urinary catheter placement days, were recorded.Results:All 15 patients were successfully completed the operation in the same position and the same robot berth without conversion. The median operation time was 103 (ranging 82-185) min, and the intraoperative median blood loss was 60 (ranging 30-120) ml. The postoperative median drainage catheter placement time was 3 (ranging 2-5) d, the postoperative median hospital stay was 5 (ranging 4-7) d, and the postoperative urinary catheters were placed for 14 days. Postoperative pathological examinations of 15 patients showed UTUC without positive margins. The median follow-up time was 15 (ranging 10-30) months. All 15 patients survived. One patient was found a recurrence in the bladder after cystoscopy. There was no tumor progression after bladder tumor resection and bladder perfusion chemotherapy, and no tumor recurrence or metastasis was seen in the remaining 14 cases.Conclusions:Robot-assisted single-position transperitoneal nephroureterectomy for UTUC does not need to change patient position and robot berth, which effectively shortens the operation time, and achieves good tumor control effect. The short-term follow-up results were satisfactory.

Objective:To apply CBL combined with PBL based on SMART (specific, measurable, attainable, relevant and time-based) principle in nursing practice teaching in radiotherapy.Methods:A total of 100 nurses who performed nursing practice in the Department of Radiotherapy in Guangdong Provincial Hospital of Traditional Chinese Medicine from May 2016 to May 2020 were selected as the research objects. They were divided into a control group and a study group according to their admissions, with 50 people in each group. The study group used CBL combined with PBL teaching based on SMART principle, and the control group used traditional practice teaching. After the clinical practice, the two groups were assessed on theoretical and clinical practice skills, and the two groups' teaching satisfaction and teaching effects were evaluated through seminars and questionnaire surveys. SPSS 22.0 was used for t test and chi-square test. Results:The theoretical and clinical practice performance assessment scores of the practical nurses in the study group were higher than those in the control group, with statistically significant differences ( P<0.001). The teaching satisfaction rate of the practice nurses in the control group was 62.00% (31/50), and that of the practice nurses in the study group was 96.00% (48/50), with significant differences ( P<0.001). In terms of improving independent learning ability, information acquisition and problem analysis ability, improving clinical thinking ability, mobilizing learning enthusiasm, enhancing teamwork ability, nurse-patient communication ability, and recognition of innovation ability, the teaching satisfaction of the research group was higher than that of the control group. Conclusion:The application of SMART principle in teaching has the advantages of clear goals and quantifiable evaluation. The combination of CBL and PBL based on SMART principle can help to improve the mastery of theoretical and practical skills of radiotherapy practice nurses, and achieve satisfactory teaching results.

Objective: To investigate the correlation between damage to the dominant arcuate fasciculus (AF) and the occurrence of auditory comprehension dysfunction in post-stroke aphasia. Methods: Eighteen stroke survivors with non-fluent aphasia were recruited into the observation group, and nine healthy counterparts were chosen for the control group. All received diffusion tensor imaging (DTI) scans and fractional anisotropy (FA) values were measured. A Chinese aphasia battery was used to evaluate the aphasics′ language functioning, with the listening true or false, listening recognition and oral instruction auditory comprehension sub-scales used as the observation indices. Results: There were significant differences between the two groups in the FA value of the dominant AF. Spearman correlation showed that the FA value of the dominant AF was positively related to the listening recognition results. Conclusions Damage to the dominant AF may be one of the reasons for auditory comprehension dysfunction in post-stroke aphasia. It is significantly related to listening recognition.

Objective To investigate the role of TLR4/NF-κB signal pathway in pathogenesis of brain inju-ry during deep hypothermia circulatory arrest(DHCA). Methods BV2 microglia cells were subjected to oxygen-glucose deprivation/reoxygenation(OGD/R),in vitro model for DHCA. The BV2 were randomly divided into the control group(C group)and the experimental group(O group). BV2 viability was determined by CCK-8 assay. TLR4 and its downstream signaling molecules ,MyD88 and phosphorylated NF-κB (p-p65) expressions were detected by Western blotting. TLR4 mRNA expression in BV2 microglial cells were determined by RT-PCR. Level of interleukin-6 (IL-6) and tumor necrosis factor alpha (TNF-α) in culture medium was detected by ELASA. Results Compared with the group C,BV2 microglia cell viability in experiment group was obviously weaker(P<0.05). Expressions of TLR4,MyD88 and phosphorylated NF-κB(p-p65)from the experiment group increased remarkedly than those from the group C (P < 0.05). TLR4 mRNA level was higher significantly in the group O than in the group C (P < 0.01). Production of IL-6 and TNF-α in the group O were up-regulated apparently compared to the group C(P<0.01). Conclusion TLR4/NF-κB signaling pathway contributed to activation of BV2 microglia cells treated by OGD/Reoxygenation ,which was probably the exactly way that involved in pathogenesis of brain injury during deep hypothermia circulatory arrest.

Objective To explore the clinical effect of salt-hot compress based on the theory of“Maiweiji”on mechanical phlebitis after PICC catheterization. Methods According to random number table, 202 patients after PICC catheterization were divided into the control group including 100 cases and the experimental group including 102 cases. The study were divided into the prevention stage and the treatment stage. In the prevention stage, the control group were given routine nursing while the experimental group were received routine nursing plus salt-hot compress. In the treatment stage, all the patients in mechanical phlebitis after the prevention stage were randomly divided into the group of salt-hot and the group of wet-hot by lottery, meanwhile, the group of salt-hot were given salt-hot compress, the group of wet-hot were received wet-hot compress. Results In the prevention stage, the mechanical phlebitis rate of the experimental group was 8.82%(9/102), and it was 21%(21/100) in the control group, the difference had statistically significant (Z=-2.28, P<0.05). In the treatment stage, the cure rate in 3 days and 7 days of the Group of Wet-hot were 5/15 and 10/15, and were 9/15 and 6/15 in the Group of Salt-hot, the average treatment time were (3.71±1.82) d and (4.31±1.58) d respectively, but the difference had no statistically significant(P > 0.05). Conclusions Salt-hot compress has the positive effect of preventing mechanical phlebitis. Besides, the therapeutic effect on mechanical phlebitis between the group of salt-hot and the group of wet-hot is about the same. Because of the simple operation, bargain price, being not contaminated clothing, salt-hot compress is more advantage.

AIM:To observe the expression of hypoxia-inducible factor 1 (HIF-1) and neuroglobin (NGB) in piglet cortex during deep hypothermic circulatory arrest.METHODS:Wuzhishan piglets were randomly assigned to car-diopulmonary bypass group ( CPB group) , 40 min of circulatory arrest ( CA) at 18 ℃ without cerebral perfusion ( DHCA group) or with selective antegrade cerebral perfusion ( SACP group) .After 180 min of reperfusion, cortical tissue was har-vested for determining HIF-1αand NGB expression by HE staining, Western blot and real-time PCR.RESULTS:Severer cerebral injury was observed in DHCA group than that in SACP group.After 180 min of reperfusion, HIF-1αprotein and mRNA levels were significantly higher in DHCA group than those in CPB group (P<0.05).Accordingly, SACP animal had higher levels of HIF-1αprotein and mRNA than those in DHCA group (P<0.05).Simultaneously, higher NGB pro-tein and mRNA levels were found in DHCA group than those in CPB group after 180 min of reperfusion ( P<0.05) .The SACP animal had higher levels of NGB protein and mRNA than those in DHCA group (P<0.05).CONCLUSION:Up-regulation of HIF-1 and NGB are involved in the mechanism against cerebral injury resulting from DHCA in the cortex and possibly a part of cerebral protective effect of SACP.
