Objective: To study the features of spontaneous isolated superior mesenteric artery dissection (SISMAD) by unexpected detection of renal artery dual-source CT (DSCT) imaging in hypertension patients. Methods: A total of 4107 patients with suspected secondary hypertension received renal artery DSCT examination in our hospital from 2010-03 to 2015-04 were studied and SISMAD was unexpectedly found in 12 patients. There were 3 patients with mild abdominal pain and the rest without obvious abdominal symptoms. The position and length, true and false lumens, detached tunica intimal flap and branch involvement of dissection, intestinal wall edema and ileus were recorded. Results: SISMAD in all 12 (0.3%) patients were found unexpectedly. Axial CT with post-processing technique clearly displayed the ruptured tunica intimal orifice, true and false lumens, detached intimal flap; the branches were all originated from true lumen. According to Sakamoto classification, all 12 patients were belong to Type I as the true and false lumens were with an entry and re-entry respectively, no filling defect in false lumen. The distance from orifice of dissection to root of abdominal aorta was (26.7 ± 11.3) mm and the length of dissection was (35.1 ± 11.7) mm.There were 10 patients with aneurysmal expansion with the diameter of (11.9 ± 2.5) mm. Conclusion: Unexpected detection of SISMAD by renal artery CT imaging was about 0.3%, radiologist should pay special attention to find superior mesenteric artery dissection in hypertension patients.

Objective To explore the effect of low frequency repetitive transranial magnetic stimulation (rTMS) on unilateral spatial neglect (USN). Methods 40 stroke patients with USN were divided into treatment group (n=20) and control group (n=20). Patients in the treatment group were treated with low frequency rTMS for 2 weeks. The USN degree of these groups were evaluated before and after the treatment. Results There was no significant difference of USN degree between these groups before the treatment (P>0.05); Compared with the control group, the treatment group improved significantly after the treatment (P<0.05). The USN degree of patients in the treatment group decreased significantly after the treatment (P<0.05), while patients in the controlled group had no difference (P>0.05). Conclusion USN induced by stroke could be improved obviously through low frequency rTMS.

Objective To assess the safety and feasibility of video electroencephalographic (VEEG) monitoring in preterm infants and critically ill neonates in neonatal intensive care unit (NICU). Method From December 2017 to June 2018, high risk infants were prospectively enrolled and received VEEG monitoring in our NICU. Their basic information, adverse events and disturbances of any procedure during VEEG monitoring were collected by specially-trained nurses. Result A total of 245 times of VEEG were recorded. The average gestational age (GA) was (32.1 ± 3.6) weeks, the birth weight (BW) was (1879 ± 757) g, the corrected GA (cGA) at VEEG monitoring was (33.8±3.3) weeks, and the average weight at VEEG monitoring was (2008±716) g. The earliest cGA at VEEG monitoring was 25+5 weeks, and the lowest weight at VEEG monitoring was 520 g. The average monitoring duration was (4.9±2.4) h, ranging from 3 to 20 hours. During VEEG monitoring, 80 cases (32.7％) received noninvasive ventilation, 43 cases (17.6％) mechanical ventilation. The adverse events during electrodes placement were oxygen desaturation in 8(3.3％) cases. During VEEG monitoring, local skin erythema were found in 4 cases (1.6％), and electrodes displacement in 2(0.8％) cases. The disturbances of any clinical procedures were reported in 18(7.3％) cases. No severe adverse events such as displacement of endotracheal tube nor events requiring cardiopulmonary resuscitation occurred during VEEG monitoring. Conclusion It is feasible and safe for trained NICU nurses to place electrodes for high risk neonates.

This paper explored the relationship between systemic lupus erythematosus （SLE） and yin-yang toxins based on the discussion of yin-yang toxin in Synopsis of the Golden Chamber （《金匮要略》）， and found that the two are similar in symptoms， and there is a potential relationship between adverse prognosis factors； and the idea that early treatment of SLE can improve prognosis is in accordance with the opinion in traditional Chinese medicine claiming that yin-yang toxin should be diagnosed and treated as soon as possible. Therefore， it is proposed to take yin-yang as general and toxin pathogen as key to explain the pathogenesis， use yin-yang toxin theory for guidance， discuss on the treatment of SLE around the pathological elements including “toxin， heat， stasis”， and take into account of the kidney essence. Accordingly， Shengma Biejia Decoction （升麻鳖甲汤） is recommended as the basic formula with modifications in accordance with different syndromes in staged treatment， providing reference for the clinical diagnosis and treatment of SLE.

Objective:To study the clinical application and complications of umbilical arterial catheterization (UAC) in premature infants.Methods:From January 2021 to December 2022, premature infants with UAC successfully inserted in NICU of our hospital were enrolled. According to birth weight (BW), the infants were assigned into three groups: <1 000 g, 1 000~1 499 g and ≥1 500 g. The perinatal data, UAC usage, UAC-related complications and risk factors of UAC-related complications were retrospectively analyzed.Results:A total of 39 premature infants received UAC, with gestational age 29.3(27.3, 30.4) weeks and BW 1 100 (900, 1 310) g. The insertion length (IL) of UAC was calculated using the average value of two formulas: a, IL (cm) =4×BW (kg) +7; and b, IL(cm) =3×BW (kg)+9. The accuracy of tube end position was determined using chest/abdomen radiography. 30(76.9%) cases had accurate position, 6(15.4%) had higher position and 3(7.7%) had lower position. The proportion of appropriately positioned tube end in <1 000 g, 1 000~1 499 g and ≥1 500 g groups were 80.0%, 76.5% and 71.4%, respectively, without statistically significant differences ( P>0.05) .No significant differences existed among the three groups in UAC duration and UAC routinely removal rate ( P>0.05). 9 cases (23.1%) of UAC were removed for specific reasons, including 4 cases of arterial spasm, 2 cases of withdrawal of treatment, 1 case of tube end displacement, 1 case of abdominal distension and 1 case of death. 21 cases received 1 U/ml heparin (0.9%NaCl solution) 0.5~1 ml/h arterial infusion. 23.8% (5/21) had hypernatremia and the level of sodium became normal after reducing the concentration of NaCl solution. Arterial vasospasm occurred in 4 patients with skin color changes of one side of the lower extremities. After UAC removal, the skin color returned to normal. Conclusions:UAC is helpful and safe for preterm infants, however, its complications should be alerted to.

ObjectiveTo explore the effect of low frequency or high frequency repetitive transcranial magnetic stimulation (rTMS) on right Broca's homologue in stroke patients with nonfluent aphasia. MethodsFrom January, 2019 to August, 2022, 80 inpatients in Beijing Bo'ai Hospital were randomly divided into control group (n = 20), sham stimulation group (n = 20), low-frequency (1 Hz) rTMS (LF-rTMS) group (n = 20) and high-frequency (10 Hz) rTMS (HF-rTMS) group (n = 20). All the patients received routine language therapy. LF-rTMS group and HF-rTMS group received ten days of rTMS (1 Hz or 10 Hz), and the sham group received ten days of sham rTMS. The Western Aphasia Battery (WAB) was used to evaluate the language function before, after treatment, and two months after treatment. ResultsBefore treatment, there was no significant difference in the scores of WAB among four groups (P > 0.05). All the scores improved in the four groups immediately after treatment and two months after treatment (P < 0.05). Compared with immediately after treatment, all the scores of WAB improved in LF-rTMS group (P < 0.05), and the scores of recall, name and aphasia quotient (AQ) improved in HF-rTMS group (P < 0.05) two months after treatment. Immediately after treatment, the scores of content and fluency, auditory comprehension and AQ were higher in LF-rTMS group than in HF-rTMS group (P < 0.05). Two months after treatment, the scores of content and fluency were higher in LF-rTMS group than in HF-rTMS group (P < 0.05). ConclusionBoth 1 Hz and 10 Hz rTMS could improve the language function of stroke patients with nonfluent aphasia, especially 1 Hz.

Objective:To assess the clinical effectiveness and safety of Omalizumab for treating pediatric allergic asthma in real world in China.Methods:The clinical data of children aged 6 to 11 years with allergic asthma who received Omalizumab treatment in 17 hospitals in China between July 6, 2018 and September 30, 2020 were retrospectively analyzed.Such information as the demographic characteristics, allergic history, family history, total immunoglobulin E (IgE) levels, specific IgE levels, skin prick test, exhaled nitric oxide (FeNO) levels, eosinophil (EOS) counts, and comorbidities at baseline were collected.Descriptive analysis of the Omalizumab treatment mode was made, and the difference in the first dose, injection frequency and course of treatment between the Omalizumab treatment mode and the mode recommended in the instruction was investigated.Global Evaluation of Treatment Effectiveness (GETE) analysis was made after Omalizumab treatment.The moderate-to-severe asthma exacerbation rate, inhaled corticosteroid (ICS) dose, lung functions were compared before and after Omalizumab treatment.Changes in the Childhood Asthma Control Test (C-ACT) and Pediatric Asthma Quality of Life Questionnaire (PAQLQ) results from baseline to 4, 8, 12, 16, 24, and 52 weeks after Omalizumab treatment were studied.The commodity improvement was assessed.The adverse event (AE) and serious adverse event (SAE) were analyzed for the evaluation of Omalizumab treatment safety.The difference in the annual rate of moderate-to-severe asthma exacerbation and ICS reduction was investigated by using t test.The significance level was set to 0.05.Other parameters were all subject to descriptive analysis.A total of 200 allergic asthma patients were enrolled, including 75.5% ( n=151) males and 24.5% ( n=49) females.The patients aged (8.20±1.81) years. Results:The median total IgE level of the 200 patients was 513.5 (24.4-11 600.0) IU/mL.Their median treatment time with Omalizumab was 112 (1-666) days.Their first dose of Omalizumab was 300 (150-600) mg.Of the 200 cases, 114 cases (57.0%) followed the first Omalizumab dosage recommended in the instruction.After 4-6 months of Omalizumab treatment, 88.5% of the patients enrolled ( n=117) responded to Omalizumab.After 4 weeks of treatment with Omalizumab, asthma was well-controlled, with an increased C-ACT score [from (22.70±3.70) points to (18.90±3.74) points at baseline]. Four-six months after Omalizumab administration, the annual rate of moderate-to-severe asthma exacerbation had a reduction of (2.00±5.68) per patient year( t=4.702 5, P<0.001), the median ICS daily dose was lowered [0 (0-240) μg vs. 160 (50-4 000) μg at baseline] ( P<0.001), the PAQLQ score was improved [(154.90±8.57) points vs. (122.80±27.15) points at baseline], and the forced expiratory volume in one second % predicted (FEV 1%pred) was increased [(92.80±10.50)% vs. (89.70±18.17)% at baseline]. In patients with available evaluations for comorbidities, including allergic rhinitis, atopic dermatitis or eczema, urticaria, allergic conjunctivitis and sinusitis, 92.8%-100.0% showed improved symptoms.A total of 124 AE were reported in 58 (29.0%) of the 200 patients, and the annual incidence was 0(0-15.1) per patient year.In 53 patients who suffered AE, 44 patients (83.0%) and 9 patients (17.0%) reported mild and moderate AE, respectively.No severe AE were observed in patients.The annual incidence of SAE was 0(0-1.9) per patient year.Most common drug-related AE were abdominal pain (2 patients, 1.0%) and fever (2 patients, 1.0%). No patient withdrew Omalizumab due to AE. Conclusions:Omalizumab shows good effectiveness and safety for the treatment of asthma in children.It can reduce the moderate-to-severe asthma exacerbation rate, reduce the ICS dose, improve asthma control levels, and improve lung functions and quality of life of patients.

Objective: To investigate the self-reported prevalence, clinical characteristics, complications of allergic rhinitis (AR) and the sensitization of outdoor air pollen allergens in children in the Inner mongolia grassland region. Methods: A multistage, stratified and random clustered sampling with a face-to-face interview survey study in children from 0 to 17 years old was performed together with 10 common allergen skin prick tests (SPT) and measurements of the daily pollen count in 6 regions in the Inner mongolia grassland region from May to August of 2015. SAS 9.4 software was used for data analysis. Results: A total of 2 443 subjects completed the study. The self-reported prevalence of AR was 26.6%. The prevalence of boys was higher than that of girls (28.8% vs 24.3%, χ²=6.157, P<0.05). Subjects from urban areas showed higher prevalence than rural areas (34.7% vs 18.8%, χ²=79.107, P<0.05). There was significant regional difference in the prevalence of AR among the six areas investigated (χ²=221.416, P<0.05). The main clinical symptoms of AR were sneezing (88.2%) and nasal congestion (78.6%). Among combined diseases, asthma accounted for 16.5% (107/650), rhinoconjunctivitis accounted for 47.9% (311/650). The peak season of AR was April and July, with the top SPT positive allergens of Artemisia species and chenopodium in this area. Conclusions The prevalence AR in children in the Inner mongolia grassland region is extremely high. Sneezing is the main clinical symptom. Rhinoconjunctivitis is the most common combined disease. High summer and autumn pollen exposure is the main cause of AR.

Objective To investigate the incidence of Holmes tremor (HT) after stroke and its outcome after medication and rehabilitation. Methods Patients diagnosed as HT after stroke in the ward of neurorehabilitation department from October, 2019 to September, 2021 were reviewed the clinical features, imaging manifestations, drug treatment plan, rehabilitation evaluation scales scores, rehabilitation plan and outcome. Results There were five inpatients with HT (0.7%, 5/715), and all were hemorrhagic stroke, accounting for 1.7% of hemorrhagic stroke. The lesions were located in the midbrain and pons in three cases, cerebellum in one case and thalamus in one case. The tremor appeared 1.5 to seven months after stroke, limited on head and limbs, with other neurological dysfunction. After the comprehensive treatment of drugs and rehabilitation, tremor improved in four cases, and ineffective in one case. The motor and balance function improved less, and the activities of daily living improved somehow. Conclusion The incidence of Holmes tremor is low in stroke patients. The tremor might respond to the treatment, but motor function would not.
