The pine sawyer Monochamus alternatus Hope (Coleoptera: Cerambycidae) is a serious pest of several Pinus species, and the ectoparasitoid larvae of Dastarcus helophoroides (Fairmaire) (Coleoptera: Bothrideridae) is an important natural enemy of this pest. The transcriptome of M. alternatus larvae was sequenced using the Illumina platform and immunity‐related genes were specifically analyzed. De novo assembly resulted in the identification of 24 241 unigenes, with a mean length of 1122 bp, in unparasitized M. alternatus larvae and 23 807 unigenes, with a mean length of 1140 bp, for parasitized larvae. Removal of redundant unigenes resulted in 26 095 all‐unigenes, of which 16 959 (64.99%) showed clear homology with some of the known genes in the National Center for Biotechnology Information nr database. Parasitization had notable effects on the transcriptome profile of M. alternatus larvae. In all, 2702 genes were differentially expressed in M. alternatus larvae after parasitization, with 1491 (55.18%) upregulated and 1211 (44.82%) downregulated. Moreover, expression levels of immunity‐related genes in M. alternatus larvae were markedly altered in response to parasitization by D. helophoroides. In conclusion, the transcriptome profiling data, especially the discovered of immunity‐related genes, help illustrate the molecular mechanisms of parasitism between D. helophoroides and M. alternatus and provide new insights into developing immunity regulation‐mediated control methods of M. alternatus.

Monochamus alternatus is a destructive stem‐boring herbivore of Pinus massoniana, and the principal vector of pine wood nematode. To investigate the impacts of boring by M. alternatus larvae on the emission of volatile organic compounds (VOCs) from their host trees, the VOCs from uninfested and M. alternatus larvae infested P. massoniana trees were observed using a gas chromatograph–mass spectrometer. We detected 12, 9, 18 and 14 volatile organic compounds from infested xylem, infested phloem, uninfested xylem and uninfested phloem, respectively. In P. massoniana xylem, the boring of M. alternatus larvae induced cyclosativene, and inhibited 4‐carene, humulene, styrene, α‐phellandrene, β‐myrcene, β‐phellandrene and γ‐terpinene. The relative amounts of camphene, copacamphene, longicyclene, longifolene, tricyclene and α‐longipinene were significantly increased, and the relative amounts of α‐pinene and β‐pinene were significantly decreased by the boring behaviors of M. alternatus larvae. In P. massoniana phloem, the boring of M. alternatus larvae induced 2‐bornanone, copacamphene, longicyclene and α‐longipinene, and inhibited 2‐carene, 4‐carene, styrene, α‐phellandrene, β‐myrcene, β‐phellandrene, β‐pinene, γ‐terpinene and ο‐cymene. The relative amounts of camphene, caryophyllene and longifolene were significantly increased by the boring behaviors of M. alternatus larvae. The results indicate that the boring behaviors of M. alternatus larvae changed both the sorts and contents of the VOCs from P. massoniana trees.

Peng Wang,You-min Guo,Min Liu,Yong-qian Qiang,Xiao-juan Guo,Yi-li Zhang,Xiao-Yi Duan,Qiu-Juan Zhang,Weifeng Liang 대한영상의학회 2008 Korean Journal of Radiology Vol.9 No.5

Objective: We aimed to do a meta-analysis of the existing literature to assess the accuracy of prostate cancer studies which use magnetic resonance spectroscopy (MRS) as a diagnostic tool. Materials and Methods: Prospectively, independent, blind studies were selected from the Cochrane library, Pubmed, and other network databases. The criteria for inclusion and exclusion in this study referenced the criteria of diagnostic research published by the Cochrane center. The statistical analysis was adopted by using Meta-Test version 6.0. Using the homogeneity test, a statistical effect model was chosen to calculate different pooled weighted values of sensitivity, specificity, and the corresponding 95% confidence intervals (95% CI). The summary receiver operating characteristic (SROC) curves method was used to assess the results. Results: We chose two cut-off values (0.75 and 0.86) as the diagnostic criteria for discriminating between benign and malignant. In the first diagnostic criterion, the pooled weighted sensitivity, specificity, and corresponding 95% CI (expressed as area under curve [AUC]) were 0.82 (0.73, 0.89), 0.68 (0.58, 0.76), and 83.4% (74.97, 91.83). In the second criterion, the pooled weighted sensitivity, specificity, and corresponding 95% CI were 0.64 (0.55, 0.72), 0.86 (0.79, 0.91) and 82.7% (68.73, 96.68). Conclusion: As a new method in the diagnostic of prostate cancer, MRS has a better applied value compared to other common modalities. Ultimately, large scale RCT randomized controlled trial studies are necessary to assess its clinical value.

It has been reported that tight sportswear could have complicated influence on physiological function of human body. The purpose of this present study was to investigate the effect of wearing gradient compression tights (GCT) on muscle strength and EMG activity during repeated isokinetic muscle contractions. Four healthy male undergraduate students performed maximal voluntary isokinetic concentric muscle contractions on biomechanical test and training systems with GCT and loose pants as control (Cont) respectively. During each test, the peak torque of extensor and flexor contractions and the surface electromyography (sEMG) of the recrus femoris and medial gastrocnemius was recorded simultaneously, the peak torque was recorded as an indicator of muscle strength, and the average amplitude and mean power frequency of sEMO were calculated as indicators of EMG activity. The results showed that: the peak torque decreased gradually during continuous muscle contractions both when the Cont and GCT were worn. average sEMG and mean power frequency declined along with the repetitions of muscle contractions for both wearing conditions, and the change tendency was consistence with that of peak torque. There was no obvious, difference between the peak torque recorded wearing the Cont or wearing GCT, but when GCT were worn, average sEMG was lower and mean power frequency was higher than the Cont condition. In 24 samples obtained from four subjects, 80% of results showed the same trend. So we could make a conclusion that wearing ocr had no obvious effect on the improvement of muscle strength, but it would affect the EMO activity posiuvly.

Background The outbreak of Coronavirus disease 2019 (COVID-19) has caused more than 180 million infections and 3.9 million deaths. To date, emerging clinical evidence has shown the synergetic benefits of Chinese herbal injections in treating this contagious respiratory disease. This review aims to summarize and analyze the efficacy and safety of Chinese herbal injections in the therapy of COVID-19. Methods The literature from 3 electronic databases, PubMed, CNKI, and Web of Science, were searched using the search terms “COVID-19”, “SARS-CoV-2”, “traditional Chinese medicine”, “herb”, “herbal”, and “injection”. Then the identified articles were comprehensively evaluated. Results Limited data demonstrated that Chinese herbal injections could significantly improve the clinical outcomes of COVID-19 patients, especially in combination with conventional treatment strategies. The benefits of which were mainly associated with the relief of symptoms, prevention of secondary infection, regulation of inflammation and immune function. There was also evidence showing the inhibitory effects on SARS-CoV-2 replication in vitro. Nevertheless, available real-world data suggested the increased risk of adverse event. Furthermore, the defects of existing researches and the insights for discovering novel antiviral drugs were prospectively discussed. Conclusion Evidence-based advances revealed that Chinese herbal injections such as XueBiJing injection and ShenMai injection, exerted potent effects against COVID-19. Further laboratory researches and clinical evaluation are needed to gather scientific evidence on the efficacy and safety.

Xiao-Juan Zhang,Li He,Hong-Ming Guo,Jie Tian,Yu-Xing Bai,Song Li 대한치과교정학회 2015 대한치과교정학회지 Vol.45 No.6

Objective: To assess the accuracy of anterior tooth movement using clear aligners in integrated three-dimensional digital models. Methods: Cone-beam computed tomography was performed before and after treatment with clear aligners in 32 patients. Plaster casts were laser-scanned for virtual setup and aligner fabrication. Differences in predicted and achieved root and crown positions of anterior teeth were compared on superimposed maxillofacial digital images and virtual models and analyzed by Student’s t-test. Results: The mean discrepancies in maxillary and mandibular crown positions were 0.376 ± 0.041 mm and 0.398 ± 0.037 mm, respectively. Maxillary and mandibular root positions differed by 2.062 ± 0.128 mm and 1.941 ± 0.154 mm, respectively. Conclusions: Crowns but not roots of anterior teeth can be moved to designated positions using clear aligners, because these appliances cause tooth movement by tilting motion.

Objective: to investigate the effect and side effects of recombinant human interleukin - 11 (rhIL - 11, in Chinese Juheli, produced by Qi Lu Biotechnology CO., LTD) in the second prevention of chemotherapy induced thrombocytopenia (CIT). Methods: Cancer patients with CIT were recruited and were treated with rhIL - 11 (treatment phase, TP), and in the following cycle, all these patients administered with rhIL - 11 24 hours immediately after chemotherapy (preventive treatment phase, PTP). Duration and severity of thrombocytopenia between two phases were compared. Results: for patients in TP or PTP, nadir values of platelet were ($29.28{\pm}20.08){\times}10^9/L$ and ($45.24{\pm}19.66){\times}10^9/L$, duration of thrombocytopenia in TP and PTP was ($11.52{\pm}4.33$) and ($8.20{\pm}+2.77$)days, recovery time was ($19.40{\pm}3.89$)and ($13.44{\pm}3.02$)days, duration of rhIL - 11 administration was ($10.68{\pm}2.46$)and ($6.28{\pm}1.77$)days, number of patients needing platelet infusion was 16and4 respectively, all differences were statistically significant (p value were 0.007, 0.002, 0.000, 0.000, 0.034 respectively). For TP and PTP, number of patients with hemorrhage was 8 and 4, duration of bleeding was ($5.00{\pm}0.82$) and ($4.50{\pm}0.71$) days respectively, with no statistically significant difference. Adverse reactions mainly included fever, edema, arrhythmia, joint pain, fatigue, skin rash, headache, dizziness, etc., all were not statistically significant between TP and PTP. Conclusion: rhIL - 11 could be well tolerated and is effective that could reduce the duration, severity of CIT, platelet transfusion, and incidence of bleeding, as well as shorten the recovery time, duration of rhIL - 11 administration. Thus, rhIL - 11 could be commended in the second prevention of CIT for patients with cancer.

( Xiao Juan Zhu ),( Shao Hui Wang ),( Ravi Jacob ),( Zhi Ning Fan ),( Fa Ming Zhang ),( Guo Zhong Ji ) 대한소화기기능성질환·운동학회 2011 Gut and Liver Vol.5 No.2

Background/Aims: Pyogenic liver abscess (PLA) is a serious, life threatening condition with a high mortality rate that represents a diagnostic and therapeutic challenge. The aim of this study was to collect demographic data and clinical, laboratory and microbiological characteristics of PLA patients treated between 2000 and 2010. We also aimed to collect information regarding our management experience of these cases. Methods: As a retrospective review, 47 patients with PLA in a tertiary referral center were examined to determine their demographic characteristics, clinical features, and laboratory, imaging, and microbiologic findings as well as the treatment outcome. Results: Cryptogenic PLA was the most frequently identified type of PLA, while benign biliary tract disease was the most frequently identifi able cause of PLA (18/47 patients; 38.3%). Leukocytosis and elevated alanine transaminase were common laboratory findings and were observed in 35 (74.5%) and 22 (46.8%) patients, respectively. Increased fibrinogen was also detected in 11 of 15 investigated cases (73.3%). Notably, infection-induced thrombocytopenia occurred in 8 patients (17%). Diabetes mellitus was associated with the occurrence of infection induced shock when compared to the non-diabetic group (p<0.05). Patients with two or more comorbid diseases had longer hospitalizations when compared to patients with one comorbid disease or those without comorbidities (p<0.001). The number of days needed to establish diagnosis was correlated with the length of hospitalization (p<0.001). The overall hospital mortality rate was 2.1% (1/47). Conclusions: Characteristics of PLA patients from the past 10 years are presented. The number of days needed to establish a PLA diagnosis was correlated with the length of the hospital stay. The hospital stay of PLA patients can be further improved by early diagnosis and effective treatments during the early stages of PLA progression. (Gut Liver 2011;5:221-227)
