ABSTRACT

Objective:To explore the relationship between small-worldness of brain network and cognitive impairment in patients with white matter lesions (WMLs) based on diffusion tensor imaging (DTI). Methods:From January, 2016 to December, 2017, 46 WMLs patients and 36 controls matched genders, ages and education levels from Beijing Tiantan Hospital were screened with DTI. The patients were divided into vascular cognitive impairment non-dementia (VCIND) and vascular dementia (VaD) groups according to the results of cognitive assessments. The brain structure network was created based on DTI data, and the topological properties of the whole-brain small-world network were calculated, and the correlation between the small-worldness and the severity of cognitive impairment was analyzed. Results:The global efficiency, local efficiency, shortest path length and clustering coefficient were different between the patients and the controls (F > 3.252, P < 0.05), as well as the properties of the small-world network, λ, γ and σ (F > 7.378, P < 0.01). The λ, γ and σ were correlated with the total score of Montreal Cognitive Assessment (|r| > 0.402, P < 0.05). Conclusion:The brain structure network is small-world network for patients with WMLs, and the decrease of small-world properties may relate to the cognitive impairment.

ABSTRACT

Objective: To review the systematic reviews of acupuncture for diabetic peripheral neuropathy (DPN) and to provide evidence for clinical decisions. Methods: Published systematic reviews targeting acupuncture treatment of DPN were searched using computer through both Chinese and English databases till July 1, 2019. Two researchers screened the papers based on inclusion and exclusion criteria and conducted report quality evaluation, methodological quality assessment and evidence quality grading using the preferred reporting items for systematic reviews and meta-analyses (PRISMA), assessment of multiple systematic review 2 (AMSTAR 2) and grading of recommendations assessment, development and evaluation (GRADE). Results: Ten systematic reviews were included, involving 11 outcome measures. According to PRISMA, 6 items were sufficiently reported while 1 item was not; AMSTAR 2 appraised that all the included systematic reviews were of low quality in the methodological evaluation; according to GRADE, of the 30 clinical evidences, only 5 were graded moderate while the remained were graded low or extremely low. Descriptive analysis showed that acupuncture can significantly improve DPN symptoms, accelerate the conduction velocities of sensory and motor nerves, and up-regulate the content of plasma nitric oxide (NO), while the adverse reaction rate was low. Conclusion: Acupuncture can produce satisfactory clinical efficacy in treating DPN, but the existing problems, such as low-quality evidence, unitary outcome measures, poor methodological quality of systematic reviews and nonstandard reporting, need to be treated cautiously; meanwhile, more high-quality clinical trials are required to elevate the level of evidence.

ABSTRACT

Abstract  Langerhans cell histiocytosis (LCH) is a disease originated from bone marrow dendritic cells, and classified as a tumor by the discovery of a recurrent somatic BRAF-V600E point mutation in the RAS-RAF-MEK-ERK signaling pathway. The clinical manifestations of LCH are mainly granulomatous lesions composed of clonal pathological tissue cells. According to the lesions and invasive risk organs, it is divided into single system diseases, multi-system diseases with risk-free organ infiltration and multi-system diseases with risk organ infiltration. The diagnosis was based on immunohistochemical pathological dendritic cell-specific markers CD1α+and/or CD207,therefore, according to risk stratification, the regiment and intensity of combination chemotherapy and targeted therapy are drawn up. Prognosis is associates with risk organ infiltration, initial treatment response, and BRAF mutations. Due to the low incidence and lack of systematic knowledge, the clinical understanding of this disease is insufficient, thus the rates of misdiagnosis and therapeutic error are high. In this review, the pathogenesis, clinical manifestations, diagnostic and treatment are summarized. So on to provide a theroretical basis for clinical diagnosis and treatment of the diseases.

ABSTRACT

Objective:To investigate the clinical features, treatment and prognosis of anti-γ-aminobutyric acid type B receptor (GABA B R) encephalitis. Methods:Retrospective analysis of five patients of anti-GABA BR encephalitis from the Department of Neurology, the University of Hong Kong-Shenzhen Hospital from September 2017 to June 2019 was carried out. Clinical manifestations, auxiliary examination, and treatment were analyzed. The patients were followed up for 3.5-23.0 months to assess their prognosis. Results:Five cases of anti-GABA BR encephalitis (19-81 years old) presented acute onset, with refractory epilepsy as the main clinical manifestation. There were hyperintensive signals on T 2/fluid attenuated inversion recovery in four patients′ temporal lobe and hippocampus. Electroencephalogram showed slow wave or epileptic discharge; Lung mass was found in four patients, and all were small cell lung cancer. Five cases had poor response to first-line immunotherapy (intravenous use of pulse methylprednisolone, high dose immunoglobulin or plasma exchange), then three patients received second-line immunotherapy (rituximab, cyclophosphamide), two of whom with tumor also received tumor chemotherapy. Patients who received second-line treatment and tumor chemotherapy showed better outcome than those who only received first-line treatment. Conclusions:Anti-GABA BR encephalitis present with limbic encephalitis syndromes characterized by refractory epilepsy. For patients with poor response to first-line immunotherapy, initiating second-line immunotherapy as soon as possible can improve the prognosis significantly.

ABSTRACT

Objective To analyze nutritional status among students participating in "nutrition improvement program" for the compulsory education students in Xi'an, and to provide a reference basis for student nutrition improvement. Methods Eleven districts and counties were selected. About 10% primary and junior high schools were selected from the nutrition improvement program. A total of 31,941 primary and junior high school students were selected. Height and weight were measured according to the standard methods. Results Malnutrition rate of 6~15 years old boys was 10.58% (stunting rate 2.40%, wasting rate 8.18%). Overweight and obesity rate was 14.23% and 11.22%, respectively. Malnutrition rate of 6~15 years old girls was 8.56% (stunting rate 2.17%, and wasting rate 6.40%). Overweight and obesity rate was 10.43% and 7.56%, respectively. The nutritional status of students in different gender, school period, feeding pattern and school location was analyzed. The malnutrition rate was higher in boys than in girls (10.58% vs 8.56%) (P<0.05). The combined obesity-overweight rate was higher in boys than girls (25.45% vs 17.99%) (P<0.05). The combined obesity-overweight rate was higher in 6~12 aged students than in 13-15 aged (22.82% vs 16.06%) (P<0.05). The combined obesity-overweight rate was higher (26.10%) (P<0.05) in the schools located in urban areas. The rate of malnutrition among students in the school-based cafeteria was higher (10.93%) (P<0.05), while the rate of overweight and obesity was higher in the students with meals supplied by the food suppling enterprise (25.18%) (P<0.05). Conclusions The malnutrition and overweight and obesity both existed in students who benefitted from the nutrition improvement program. Attention should be paid to the malnutrition of boys and county schools, the overweight and obesity of boys, 6-12 years old students, and urban students. It is suggested that while implementing the nutrition improvement plan, the nutrition health education in students should be strengthened to avoid an increase of overweight and obesity rate.

ABSTRACT

OBJECTIVE@#To explore the effects of different concentration of pomalidomide on human multiple myeloma cell line MM1.S and the expression of CRBN.@*METHODS@#CCK-8 method was used for detecting inhibition effect of promalidomide on proliferation of MM1.S cells. Apoptosis rate of MM1.S cells was detected by flow cytometry with Annexin V-FITC/PI double staining. Real-time quantitative PCR was used to determine CRBN gene expression level. Western blot was used to detect the effect of pomalidomide on the protein expression of CRBN in MM1.S cells.@*RESULTS@#Pomalidomide has an inhibitory effect on MM1.S cells with time-and dose-dependent manners. Pomalidomide induced apoptosis in MM1.S cells. When the concentration of pomalidomide was 0, 40 and 80 μmol/L, the expression of CRBN gene after the treatment of MM1.S cells for 72 hours was 1.487±0.340, 0.211±0.054 and 0.055±0.005, by using actin as internal refereme. Pomalidomide significantly reduced CRBN protein expression in MM1.S cells.@*CONCLUSION@#Pomalidomide can inhibit the proliferation of MM1.S cells and promote its apoptosis. A certain concentration of pomalidomide can reduce the expression of CRBN gene and down-regulate its protein expression in MM1.S cells.

ABSTRACT

Objective To analyze the clinical characteristics of pheochromocytoma crisis (PCC). Meth-ods Data of 123 cases of pheochromocytoma and paraganglioma (PPGL) admitted from Apr. 2011 to Feb. 2017 were retrospectively analyzed and they were divided into crisis group and noncrisis group according to the pa-tients with or without haemodynamic instability and end-organ damage. The differences of demographics charac-teristics, presentations, laboratory tests, imaging findings, perioperative clinical conditions and pathological fea-tures were compared between the two groups. Results ①16 cases were enrolled into crisis group, among whom 5 were misdiagnosed, while 107 cases were enrolled into noncrisis group. ②Compared with noncrisis group, the incidence of headache, palpitation, sweating, the classic triad, other presentations of PPGL, severe hypertension and hypotension were higher, and more patients had paroxysmal hypertension and admitted to our hospital for paroxysmal presentations in crisis group (P<0.05). ③Leukocyte, fasting blood glucose, liver transaminases, tro-ponin and D-dimmer were higher, while estimated glomerular filtration rate(eGFR) was lower, more tumors locat-ed in the left of adrenal in crisis group(P<0.05). ④ Patients in crisis group had higher plasma free metanephrines (MNs), larger maximal tumor diameter, higher enhanced CT value in each period, more benign tumors and hem-orrhage or necrosis in the tumors, but all the differences were not significant when compared with the noncrisis group. ⑤Patients in crisis group were more likely to undergo elective surgery. However, there was no difference in the preoperative time of α-blockade, type of surgery, intraoperative and postoperative complications, mortality a-mong the two groups. Conclusions PCC is a rare endocrinological emergency with a highly variable manifesta-tions, which commonly presents with typical triad, with higher incidence of hemodynamic instability and end-organ damage. Although biochemical and imaging examinations are relatively effective in the diagnosis of PCC, the mis-diagnosis remains inappropriate high. Once the diagnosis is established, clinicians should timely start drug prepa-ration while surgical resection is the key to the treatment of PCC.

ABSTRACT

Objective@#To understand the homosexual behavior and related factors among married MSM in Mianyang city.@*Methods@#Between January and October in 2017, a snowball sampling method was adopted to carry out cross-sectional survey through questionnaires plus HIV testing among those MSM in Mianyang city. Logistic regression model was used to analyze homosexual behaviors and related factors among married MSM under study. Statistical analysis was used by EpiData 3.1 and SPSS 19.0 software.@*Results@#A total of 234 MSM participated in this survey. The overall rate of homosexual behavior in these married MSM appeared as 94.9% (222/234). Rate of having anal sex behavior was 94.4% (221/234) in the past 6 months, with rate of condom use as 57.9% (128/221). HIV positive rate was 8.1% (18/222). As for the motives for homosexual behavior after marriage, 87.8% (195/222) were driven by feelings of love, 12.2% (27/222) due to 'releasing pressure’. Proportion of male sex partners would include occasional sex partners (62.2%, 138/222), stable male sex partners (26.1%, 58/222) and stable boyfriends (11.7%, 26/222). Factors from logistic regression analysis showed that homosexual behaviors were related to the factors including education level of senior high school or above vs. education level of junior middle school or below (OR=3.65, 95%CI: 1.33-9.98); local residency over one year vs. the ones having local residency less than one year (OR=23.28, 95%CI:1.67-324.89); having 10 or more friends in the MSM community vs. having below 10 friends in MSM community (OR=4.15, 95%CI: 1.28-13.43); without sex pleasure with spouse vs. having sex pleasure with spouse (OR=3.25, 95%CI: 1.22-8.62); having 2 or more anal sex partners in the past 6 months vs. having less than 2 anal sex partners in the past 6 months (OR=0.28,95%CI: 0.09-0.81).@*Conclusions@#The rate of homosexual behavior and HIV positive rate were high among MSM in Mianyang city. Homosexual behaviors after marriage were influenced by multiple factors among MSM. The motives of homosexual behavior after marriage were driven by feelings of love, the related factors were education level of senior high school or above, local residency over one year, having 10 or more friends in the MSM community and without sex pleasure with spouse. As for the motives of these behaviors was caused by releasing pressure, the related factors was having more than 2 anal sex partners.

ABSTRACT

Myelofibrosis, a clonal stem-cell disorder which is difficult to cure, The treatment for most of patients is conservative treatment, but the treatment effect is not ideal. Lenalidomide as a novel immunomodulator in the treatment of blood diseases showed good results in recent years, Its studies have shown that lenalidomide in myelofibrosis also showed a certain effect. As companed with single drug lenalidomide, the thalidomide has a higher response rate, clinical symptoms improved significantly. Ruxolitinib, JAK2 inhibitor, combined with lenalidomide not only can improve the quality of life of patients, but also extend the survival of patients. In addition, lenalidomide combined with prednisone for the treatment of bone marrow fibrosis is more effective and more safe, lenalidomide can significantly improve the clinical symptoms of patients, especially anemia, and prednisone can reduce the hematologic toxicity of lenalidomids. The purpose of this review is to evaluate the efficacy and safety of lenalidomide in the treatment of myelofibrosis, and focuses on the newest clinical research and application progress of lenalidomide for myelofibrosis.
