Glucocorticosteroid-induced osteoporosis is the most frequent of all secondary types of osteoporosis, and can increase the risk of vertebral compression fractures (VCFs). There are promising additions to current medical treatment for appropriately selected osteoporotic patients. Few studies have reported on the efficiency of percutaneous vertebroplasty (PVP) or kyphoplasty for whole thoracic and lumbar glucocorticosteroid-induced osteoporotic vertebral compression fractures. We report a case of a 67-year-old man with intractable pain caused by successional VCFs treated by PVP.

Objective: Clozapine is one of the most commonly used antipsychotic drugs in China. To date, few studies have investigated the patterns the prescription of clozapine nationwide. The present study examined these patterns in China in 2006 and identified the demographic and clinical characteristics associated with the use of clozapine. Methods: Using a standardized protocol and data collection procedure, we surveyed 5,898 patients with schizophrenia in 10provinces with differing levels of economic development. Results: Overall, clozapine had been prescribed for 31.9% (n=1,883) of the patients; however we found considerable variation among the 10 provinces. The frequency of clozapine use was highest in Sichuan (39.3%) and lowest in Beijing (17.3%). The mean daily dose of clozapine was 210.36±128.72 mg/day, and 25.1% of the patients were treated with clozapine in combination with other antipsychotics. Compared with the group not receiving clozapine, clozapine-user had been treated for longer durations and had experienced a greater number of relapses and hospitalizations. Furthermore, those in the clozapine-user had lower family incomes, were less able to seek psychiatric services, and more likely to be male and have a positive family history of schizophrenia. A multiple logistic regression analysis revealed that age, sex, professional help-seeking behaviors, duration of illness, economic status, educational level, and clinical manifestations were associated with the use of clozapine. Conclusion: Clozapine use is common in China. However, use of the antipsychotic varies among provinces, and demographic and clinical factors play important roles in the prescription of clozapine.

Objective: To investigate the patterns of antipsychotic use in China and to analyze the factors that influence antipsychotic prescriptions. Methods: A standardized survey was conducted from May 20 to 24 2002 in five different regions of China with varying economic levels. The patterns of antipsychotic medication use were analyzed in a sample of 4,779 patients with schizophrenia. The survey gathered information on demographic characteristics, clinical profiles, and antipsychotic medications prescribed. Multiple logistic regression was used to analyze factors related to patterns of antipsychotic medication use. Results: A plurality of patients with schizophrenia was treated with clozapine (39%); this was followed by risperidone, sulpride,chlorpromazine, perphenazine, and haloperidol. More than 56.3% of patients were treated with only one atypical antipsychotic. The mean daily dose of chlorpromazine was 365±253 mg (mean±standard deviation), and 6.5% of patients were treated with depot injections of typical antipsychotic medications. A total of 73.7% (n=3,523) of patients with schizophrenia received monotherapy,24.8% (n=1,183) received two antipsychotics, 1.1% (n=52) received three antipsychotics, and one received four different antipsychotics. Patients often simultaneously received other classes of medications including anticholinergic agents, benzodiazepines,β-blockers, antidepressants, and mood stabilizers. Economic status and clinical symptoms were the main factors that contributed to the patterns of antipsychotic prescription. Conclusion: The present study suggests that atypical antipsychotic medications, especially clozapine, are the primary psychiatric treatments of choice in the management of schizophrenia in China. Moreover, the economic status and clinical profile of the patient are the major factors affecting the prescription of antipsychotic medication.

Percutaneous Sacroplasty for Painful Sacral Metastases Involving Multiple Sacral Vertebral Bodies: Initial Experience with an Interpedicular Approach

Qing-Hua Tian,He-Fei Liu,Tao Wang,Ying-Sheng Cheng,Chun-Gen Wu 대한영상의학회 2019 Korean Journal of Radiology Vol.20 No.6

Objective: To report our initial experience of percutaneous sacroplasty (PSP) with an interpedicular approach for treating painful sacral metastases involving multiple sacral vertebral bodies. Materials and Methods: This study prospectively enrolled 10 consecutive patients (six men and four women; mean age, 56.3 ± 13.8 years) who underwent PSP for painful sacral metastases involving multiple sacral vertebral bodies from March 2017 to September 2018. Visual analogue scale (VAS) scores, Oswestry disability index (ODI) values, and the number of opioids prescribed to the patients were assessed before and after PSP. The procedure duration, length of hospitalization, and complications were also recorded. Results: Mean VAS and ODI declined significantly from 6.90 ± 1.20 and 74.40 ± 5.48 before the procedure to 2.70 ± 1.34 and 29.60 ± 14.57 after the procedure, respectively (p < 0.01). The median number of opioids prescribed per patient decreased from 2 (interquartile range [IQR] 1–3) pre-procedure to 1 (IQR 0–3) post-procedure (p < 0.01). Nine of the 10 patients showed no or decreased opioid usage, and only 1 patient showed unchanged usage. The mean procedure duration was 48.5 ± 3.0 minutes. The average length of hospitalization was 4.7 ± 1.7 days. Extraosseous cement leakage occurred in three cases without causing any clinical complications. Conclusion: PSP with an interpedicular approach is a safe and effective treatment in patients with painful sacral metastases involving multiple sacral vertebral bodies and can relieve pain and improve mobility.

Xiaoqing Tian,Ying-Hua Ling,Li-kui Fang,Peng Du,Xian-Chun Sang,Fang-Ming Zhao,Yun-Feng Li,Rong Xie,Guang-Hua He 한국유전학회 2013 Genes & Genomics Vol.35 No.1

Chlorophyll is an important photosynthetic pigment in the process of photosynthesis in plants and photosynthetic bacteria. Genes involved in chlorophyll biosynthesis in Arabidopsis and photosynthetic bacteria have been well documented. In rice, however, these genes have not been fully annotated. In this paper, a yellow-green leaf gene, yellow green leaf3 (ygl3) was cloned and analyzed. ygl3 encodes magnesium chelation ChlD (D) subunit,a key enzyme for chlorophyll synthesis, resulting in a yellow-green leaf phenotype in all growth stages in rice. Expression content of ygl3 is highest in the leaf blades,followed by the leaf sheaths, while there is virtually no expression of the gene in the stems and seeds. The subcellular structure and protein content of the photosynthetic system of the ygl3 mutant were revealed by transmission electron microscopy, BN-PAGE, and western blotting. The results show that the mutation of the ygl3 gene indirectly leads to a decrease in the protein content of the photosynthetic system and severely obstructs the formation of granum thylakoids.

Pan, Feng,Tian, Jing,Ji, Chu-Shu,He, Yi-Fu,Han, Xing-Hua,Wang, Yong,Du, Jian-Ping,Jiang, Feng-Shou,Zhang, Ying,Pan, Yue-Yin,Hu, Bing Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.11

Published data on the associations between tumor necrosis factor-alpha (TNF-${\alpha}$) promoter -308G>A and -238G>A polymorphisms and cervical cancer risk are inconclusive. To derive a more precise estimation of the relationship, a meta-analysis was performed. Data were collected from MEDLINE and PubMed databases. Crude odds ratios (ORs) with 95% confidence intervals (CIs) were calculated in a fixed/random effect model. 13 separate studies including 3294 cases and 3468 controls were involved in the meta-analysis. We found no association between TNF-${\alpha}$-308G>A polymorphism and cervical cancer in overall population. In subgroup analysis, significantly elevated risks were found in Caucasian population (A vs. G: OR = 1.43, 95% CI = 1.00-2.03; AA vs. GG: OR = 2.09, 95% CI = 1.34-3.25; Recessive model: OR = 2.09, 95% CI = 1.35-3.25) and African population (GA vs. GG: OR = 1.53, 95% CI = 1.02-2.30). An association of TNF-${\alpha}$-238G>A polymorphism with cervical cancer was found (A vs. G: OR = 0.61, 95% CI = 0.47-0.78; GA vs. GG: OR = 0.59, 95% CI = 0.45-0.77; Dominant model: OR = 0.59, 95% CI = 0.46-0.77). When stratified by ethnicity, similar association was observed in Caucasian population (A vs. G: OR = 0.62, 95% CI = 0.46-0.84; GA vs. GG: OR = 0.59, 95% CI = 0.43-0.82; Dominant model: OR = 0.60, 95% CI = 0.44-0.83). In summary, this meta-analysis suggests that TNF-${\alpha}$-238A allele significantly decreased the cervical cancer risk, and the TNF-${\alpha}$-308G>A polymorphism is associated with the susceptibility to cervical cancer in Caucasian and African population.

Zhang-Zhang He,Jie Luo,Lian-You Gui,Deng-Ke Hua,Tian-Hua Du,Fu-Lian Wang,Peng Liang,Yong-Fang Shi,Xuan Yang 한국응용곤충학회 2019 Journal of Asia-Pacific Entomology Vol.22 No.3

Previous work reveals that the adult Chinese citrus fly, Bactrocera minax (Enderlein), emerges from the ground in citrus orchards and presumably disperses to alternate food sources in neighboring shrubs and trees, where it stays and becomes reproductively mature, and then later returns to the orchard to lay eggs. We investigated the trajectories of early emerged adult Chinese citrus flies, which were tracked with portable harmonic radar in 2013, 2014, 2015, and 2016 in four different habitats in Hubei province of China that presumably provided food sources for adults. This study we investigated whether early emerged adult Chinese citrus flies migrate into forests. A total of 47 adults were tracked following release in a citrus orchard. Our results showed that a total of 33 adults released in a citrus orchard flew into the forest, and 14 adults that disappeared during the tracking process in the citrus orchard. A total of 10 adults (in 2014) that were tracked and released in the forest flew to the forest. Of the adult flies investigated, 54.5% flew directly into the forest, while the remaining 45.5% finally arrived in the forest after repeatedly adjusting their trajectories. When there were Castanea mollissima Blume (Fagaceae) in the surrounding forest, the proportion of frequency of adult landing on the plant represented 58.3% and 88.5% of landing on all species in 2014 and in 2015, respectively. We conclude that early emerged adult Chinese citrus flies in the mosaic-type citrus orchard of the hilly terrain landform dispersed into adjacent forest.

Corynebacterium defluvii sp. nov., isolated from Sewage

Qiu-Li Yu,Zheng-Fei Yan,Xin He,Feng-Hua Tian,Chuan-Wen Jia,Chang-Tian Li 한국미생물학회 2017 The journal of microbiology Vol.55 No.6

A Gram-positive, aerobic, non-motile, rod-shapeds, cata-lase-positive, and oxidase-negative strain, designated Y49T, was isolated from sewage collected from Jilin Agricultural University, China. It grew at 20–40°C (optimum at 30°C), at pH 6.0–8.0 (optimum at 7.0) and at 0–1.0% sodium chlo-ride (optimum at 0%). The major isoprenoid quinone was menaquinone-8 (MK-8) and the polar lipids were diphos-phatidylglycerol, phosphatidylglycerol, phosphatidylmethy-lethanolamine, four unidentified lipids, and two unidenti-fied aminolipids. The peptidoglycan was meso-diaminopi-melic acid. The cell-wall sugars were galactose, arabinose, and glucose. The fatty acids were C9:0, C16:0, C16:1 ω9c, C17:1 ω9c, C18:3 ω6c (6,9,12), C18:1 ω9c, and C18:0. The DNA G+C content was 51.4 mol%. Based on the 16S rRNA gene se-quence analysis, the nearest phylogenetic neighbors of strain Y49T were Corynebacterium efficiens DSM 44549T (97.5%), Corynebacterium callunae DSM 20147T (97.2%), Coryne-bacterium deserti GIMN 1.010T (96.8%), Corynebacterium glutamicum ATCC 13032T (96.4%), and other species belong-ing to this genus (92.3–95.4%). The DNA-DNA relatedness value between strain Y49T and C. efficiens DSM 44549T, C. callunae DSM 20147T, C. deserti GIMN1.010T, and C. gluta-micum ATCC 13032T was 25.5±2.0%, 21.1±1.0%, 16.5±0.5%, and 13.5±0.9%, respectively. Based on the phylogenetic an-alysis, chemotaxonomic data, physiological characteristics and DNA-DNA hybridization data, strain Y49T represents a novel species of the genus Corynebacterium, for which the name Corynebacterium defluvii sp nov. is proposed. The type strain is Y49T (= KCTC 39731T =CGMCC 1.15506T).
