Percentage of tonsil hypertrophy in orthodontic patients with different sagittal skeletal relationship / 中华口腔医学杂志

Objective: To investigate the prevalence of tonsil hypertrophy in patients with different sagittal skeletal craniofacial patterns, as well as the correlation between tonsil hypertrophy and the type of skeletal pattern. Methods: Lateral cephalograms of patients who visited the Department of Orthodontics Division 1, School of Stomatology, Wuhan University during January to August, 2019 were retrospectively collected. Patients (children: age≥6 and ≤12 year; adults: age≥18 year) were divided into three groups according to the ANB (subspinale-nasion-supramental) angle: the skeletal class Ⅰ group (0°≤ANB≤4°), skeletal class Ⅱ group (ANB>4°) and skeletal class Ⅲ group (ANB<0°). Tonsil hypertrophy was diagnosed with lateral cephalogram by two specifically trained orthodontists independently, according to the Baroni's method. The between-group differences in tonsil hypertrophy prevalence were analyzed using chi-square tests with Bonferroni correction (α=0.017). Results: A total of 1 776 patients (593 children and 1 183 adults) were included, among which 672 (37.8%) were with class Ⅰ, 849 (47.8%) with class Ⅱ, and 255 (14.4%) with class Ⅲ skeletal pattern. The prevalence of tonsil hypertrophy in children was 66.3% (393/593). The proportion of children with tonsil hypertrophy in class Ⅲ group [87.0% (60/69)] were significantly higher than that in class Ⅰ [65.6% (145/221), χ²=11.56, P<0.017] and class Ⅱ [62.0% (188/303), χ²=15.69, P<0.017] groups. The prevalence of tonsil hypertrophy in adults was 23.2% (275/1 183). The proportion of adults with tonsil hypertrophy in class Ⅲ group [42.5% (79/186)] was significantly higher than that in class Ⅰ [19.1% (86/451), χ²=36.50, P<0.017] and class Ⅱ [20.2% (110/546), χ²=35.00, P<0.017] groups. However, there was no significant difference in the prevalence of tonsil hypertrophy between class Ⅰ and class Ⅱ groups for both children (χ²=0.70, P>0.017) and adults (χ²=0.18, P>0.017). Conclusions: The prevalence of tonsil hypertrophy in skeletal class Ⅲ patients was significantly higher than that in patients with skeletal class Ⅰ and Ⅱmalocclusion. Tonsil hypertrophy could be an important risk factor for skeletal class Ⅲ patients.

MethodUltra high performance liquid chromatography tandem quadrupole orbitrap high resolution mass spectrometry （UHPLC-Q-Orbitrap HRMS） was used to qualitatively analyze the main chemical components in water extract of Chuanxiong Rhizoma based on the spectral information of compound， comparison of reference substance and references. The chemical pattern recognition method was used to screen the differential components of Chuanxiong Rhizoma before and after processing. Based on these differential components， the potential targets of differential components were predicted by online databases， and the related targets of cerebral ischemia were searched. Cytoscape 3.6.0 was used to establish the network diagram of differential components-action targets-diseases of Chuanxiong Rhizoma processed with wine. The protein-protein interaction （PPI） network of intersection targets was constructed by STRING 11.5. The potential targets of differential components against cerebral ischemia were analyzed by Gene Ontology （GO） and Kyoto Encyclopedia of Genes and Genomes （KEGG） enrichment analysis through DAVID 6.8. At the same time， the chemical compounds with high relative content and increased peak area after wine processing were docked with their corresponding targets to verify the mechanism of enhanced effect after wine processing. ResultA total of 71 chemical components were identified from Chuanxiong Rhizoma， 34 differential components and 603 potential targets were screened out. At the same time， a total of 769 disease targets and 60 intersection targets were obtained. Seven key targets were identified through PPI network analysis， including JUN， signal transducer and activator of transcription 3 （STAT3）， mitogen-activated protein kinase 3 （MAPK3）， interleukin-1β （IL-1β）， vascular endothelial growth factor A （VEGFA）， Caspase-3 （CASP3） and mtrix metalloproteinase 9 （MMP9）. Tumor necrosis factor （TNF） signaling pathway was the main differential signaling pathway. The results of molecular docking showed that differential components （senkyunolide K， senkyunolide F， 3-n-butylphthalide， Z，Z′-6，8′，7，3′-diligustilide， ferulic acid and Z-ligustilide） and corresponding targets had good binding activities. ConclusionThe synergistic mechanism of Chuanxiong Rhizoma processed with wine may be related to the enhanced inhibitory effect of inflammatory reaction.

Material Attribute Research in Quality Control of Traditional Chinese Medicine Pills： A Review / 中国实验方剂学杂志

As intelligent production of traditional Chinese medicine （TCM） has been inevitable， informatization and automation of the production process have become the precondition for realizing intelligent manufacturing of TCM， of which the accumulation of critical material attribute and the critical quality attribute are the basis. The study of material properties is of great significance to achieve the quality control of the final product in the process， but there is a lack of systematic induction and summary of the research on the attribute of TCM pills. Therefore， the authors analyzed and summarized the attributes of raw materials， excipients and intermediates in the pill unit process according to the classification of powder properties， rheological properties and texture properties. What’s more， the impact of material attributes on the quality of the final product was summarized. Besides， this review summarized the attribute characterization techniques involved in the pill process and provided some suggestions for the characterization of product quality attributes. Finally， based on the concept of quality by design （QbD）， the authors proposed that the study of material attribute should be combined with process analytical technology （PAT）， and the focus of drug quality control should be moved forward to guide equipment upgrading， so as to realize intelligent continuous manufacturing of TCM pills.

ObjectiveTo investigate the effect of Biejiajian Wan （BJJW） on transforming growth factor-β1 （TGF-β1）-induced epithelial-mesenchymal transition （EMT） of HepG2 cells， and explore its mechanism against EMT of hepatocellular carcinoma cells. MethodHepG2 cells were randomly divided into a blank group， a TGF-β1 model group （10 μg·L-1 TGF-β1）， a low-dose BJJW group （10 μg·L-1 TGF-β1+0.55 g·kg-1 BJJW）， a medium-dose BJJW group （10 μg·L-1 TGF-β1+1.1 g·kg-1 BJJW）， a high-dose BJJW group （10 μg·L-1 TGF-β1+2.2 g·kg-1 BJJW）， and a sorafenib group （10 μg·L-1 TGF-β1+0.03 g·kg-1 sorafenib）. The EMT model was induced by 10 μg·L-1 TGF-β1 in HepG2 cells. After treatment with corresponding medicated serum， cell counting kit -8 （CCK-8） assay was used to detect cell proliferation. Cell migration ability was detected by the Transwell assay and wound healing assay. The protein expression related to EMT and nuclear factor-kappa B （NF-κB） signaling pathway was detected by cell immunofluorescence assay and Western blot. ResultCompared with the blank group 4 days later， the TGF-β1 model group showed fusiform and loose cells with widened gap and antennae reaching out， decreased protein expression of E-cadherin （P<0.05）， and increased protein expression of N-cadherin and vimentin （P<0.05）， which indicated that the EMT model was properly induced in HepG2 cells by TGF-β1 stimulation for 4 days. After 48 hours of treatment with the corresponding medicated serum， each medication group showed inhibited proliferation of HepG2 cells that had undergone EMT， especially the low- and high-dose BJJW groups （P<0.01）， and the medium-dose BJJW group showed increased E-cadherin protein expression （P<0.05） and decreased p-p65， N-cadherin， and vimentin protein expression （P<0.05）， as compared with the TGF-β1 model group. As revealed by the transwell assay and wound healing assay， TGF-β1 enhanced the migration ability of HepG2 cells （P<0.05， P<0.01） compared with the results in the blank group， compared with the TGF-β1 model group， the medication groups showed inhibited migration ability of HepG2 cells （P<0.05， P<0.01）. Compared with the blank group， the TGF-β1 model group promoted the expression of p65 and Snail into the nucleus. Compared with the TGF-β1 model group， the medication groups inhibited the expression of p65 and Snail into the nucleus. ConclusionBJJW may inhibit the EMT， proliferation， and migration of HepG2 cells induced by TGF-β1 by suppressing the NF-κB signaling pathway to exert an anti-hepatocellular carcinoma effect.

Butyl alcohol extract of Baitouweng Decoction alleviates vulvovaginal candidiasis in mice by downregulating NLRP3 inflammasome and related signal pathways / 中国中药杂志

This study aims to explore the effect of butyl alcohol extract of Baitouweng Decoction(BAEB) on vulvovaginal candidiasis(VVC) in mice and to clarify the mechanism from Toll-like receptors(TLRs)/MyD88 and Dectin-1/Syk signal pathways and NLRP3 inflammasome. To be specific, female KM mice were randomized into control group(i.g., normal saline), model group, fluco-nazole group(i.g., 20 mg·kg~(-1)), and low-dose, medium-dose, and high-dose BAEB groups(i.g., 20, 40, and 80 mg·kg~(-1), respectively). VVC was induced in mice except the control group. After the modeling, administration began and lasted 7 days. The ge-neral conditions and body weight of mice were recorded every day. On the 1 st, 3 rd, 7 th, and 14 th after vaginal infection by Candida albicans, the fungal load in the vaginal lavage fluid of the mice was measured with the plate method, and the morphology of C. albicans in vaginal lavage fluid was observed based on Gram staining. After the mice were killed, vaginal tissues were subjected to hematoxylin-eosin(HE) staining and periodic acid-Schiff(PAS) staining for vaginal histopathological analysis. The content of cytokines in vaginal lavage fluid, such as interleukin(IL)-1β, IL-18, tumor necrosis factor-α(TNF-α), IL-6, and S100 a8, was determined by enzyme-linked immunosorbent assay(ELISA), and content of reactive oxygen species(ROS) in vaginal tissues by tissue ROS detection kit. The protein expression of NLRP3, ASC, caspase-1, Dectin-1, Syk, MyD88, TLR2, TLR4, and nuclear factor-κB(NF-κB) in vaginal tissues was detected by Western blot, and the levels and distribution of NLRP3, Dectin-1, Syk, MyD88, TLR2, and TLR4 in vaginal tissues were determined with the immunohistochemical method. The results show that BAEB can improve the general conditions of VVC mice, reduce the fungal load and C. albicans hyphae in vaginal secretion, decrease ROS content in vaginal tissues and content of cytokines in vaginal lavage fluid, and down-regulate the expression of NLRP3, ASC, caspase-1, Dectin-1, Syk, MyD88, TLR2, TLR4, and NF-κB in vaginal tissues. The above results indicate that BAEB exerts therapeutic effect on VVC mice by down-regulating the key proteins in the TLRs/MyD88 and Dectin-1/Syk signal pathways and NLRP3 inflammasome.

Objective:To explore the alteration of JAK2/STAT3 pathway after carbon ion ( 12C 6+) irradiation and the difference in the infiltration of CD8 + T cells in lung cancer regulated by downstream protein FOXP3. Methods:Significantly altered JAK2/STAT3 pathway and related differentially-expressed genes and proteins such as FOXP3 in lung cancer after carbon ion irradiation were screened based on RNA sequencing analysis in the Lewis tumor model of C57BL/6 mice. The correlation between FOXP3 and major immune cell infiltration in the immune microenvironment of lung cancer was analyzed using the ssGSEA immune infiltration algorithm in the R software "GSVA" and CD8 + T cell infiltration in the immune microenvironment of lung cancer was evaluated based on the carbon ion combined with STAT3 inhibition pathway (niclosamide). Results:The JAK2/STAT3 pathway was inhibited and the expression of related genes and proteins was downregulated in lung cancer after carbon ion irradiation. Immune scoring based on the ssGSEA algorithm showed that FOXP3 expression was significantly negatively correlated with CD8 + T cell infiltration in the immune microenvironment of lung cancer. The role of targeting the JAK2/STAT3 pathway in increasing CD8 + T cell infiltration in lung cancer was further clarified by carbon ion irradiation combined with STAT3 inhibition (niclosamide). Conclusion:Carbon ion irradiation ( 12C 6+) can play a synergistic role with immunotherapy by targeting the JAK2/STAT3 pathway.

The application of blood oxygen level dependent functional magnetic resonance imaging (BOLD-fMRI) to the protection of language functional area during postoperative IMRT of cerebral gliomas / 中华放射医学与防护杂志

Objective:To investigate the clinical application value of blood oxygen level dependent functional magnetic resonance imaging (BOLD-fMRI) to the protection of language function in patients with unilateral frontal and temporal lobes glioma receiving postoperative intensity modulation radiation therapy (IMRT).Methods:A total of 27 patients with unilateral frontal and temporal lobe gliomas were treated with postoperative radiotherapy. The planning CT and BOLD-fMRI were performed before radiotherapy, and the language functional areas were delineated based on the fused images of 3D T1 and CT. IMRT technology was used to develop radiotherapy plans with and without language function area protection, naming conventional and protective radiotherapy plans respectively. The maximum radiation dose ( Dmax), average radiation dose ( Dmean), target conformal (CI) and dose uniformity (HI) of PTV of the two plans were compared and analyzed to ensure that the protective radiotherapy plan could meet the radiotherapy standard. Then, the Dmax and Dmean of the language function area were compared and analyzed to evaluate whether the Dmax and Dmean of the language function area were decreased in the protective radiotherapy plan. Results:There were no significant differences in CI, HI, Dmax and Dmean of PTV between the conventional radiotherapy plan and protective radiotherapy plan ( P>0.05). There were statistically significant differences in Dmax and Dmean of Wernicke′s and Broca′s (healthy side and affected side) between the conventional radiotherapy plan and protective radiotherapy plan ( t=3.073-12.707, P<0.05). Dmax and Dmean of Wernicke′s and Broca′s (healthy side and affected side) were decreased in the protective radiotherapy plan compared with the conventional radiotherapy plan, and the decrease was significant in the healthy side. Conclusions:BOLD-fMRI combined with IMRT can not only guarantee the target dose of patients with glioma receiving postoperative radiotherapy, but also reduces the radiation dose to the language function area. Chinese reading task and paragraph comprehension task are the stimulation mode of language function in patients after brain tumor surgery. These tasks are simple and the effect is accurate.

On the whole ，top 4 orthopedic diseases in the list of the consumption of tranexamic acid were joint replacement （25.5％-29.6％），hip fracture （19.3％-23.6％），diaphysis fracture （13.5％-18.6％）and pelvic and acetabular fracture （8.2％-14.0％）. The route of administration for tranexamic acid in spinal surgery department ，joint surgery department and orthopedic trauma department was mainly intravenous application every year （accounting for 55.1％-81.0％，46.9％-77.1％，49.3％-73.3％，44.9％-71.5％）. CONCLUSIONS ：The consumption of tranexamic acid in orthopedic inpatients is increased year by year ，and is dominated by joint surgery department and orthopedic trauma department. The route of tranexamic acid is still mainly intravenous administration ，which is safe and reliable.

Botanical origin identification of Rhei Radix et Rhizoma based on color digitalization / 中国中药杂志

The color characteristic information of Rhei Radix et Rhizoma powder was obtained by spectrophotometer, the feasibility of rapid identification of Rhei Radix et Rhizoma origin based on chromaticity value was studied by statistical analysis. The results of rank correlation analysis showed that a~*(P<0.01), b~*(P<0.01) had significantly correlation with the origin of medicinal herbs, which could be used as two important parameters to distinguish the origin of Rhei Radix et Rhizoma, the larger the a~* value, the more red the powder color,and the greater the b~* value, the more yellow the powder color. Meanwhile, through Fisher discriminant analysis, the linear discriminant functions of different genus Rhei Radix et Rhizoma were established, which was Rheum tanguticum=40.666a~*+0.019b~*-213.303, Rh. palmatum=34.121a~*+0.061b~*-151.770, Rh. officinale=28.071a~*+0.113b~*-104.604 3, the coincidence rate of cross-validation was over 95%, among them, the discriminant rate of Rh. tanguticum and Rh. officinale reached 100%;In addition, using the percentile method to analyze the 90% reference value range of three different origin of Rhei Radix et Rhizoma, as a result, Rh. tanguticum a~*(10.236 5-10.604 7), b~*(32.294 8-34.841 7); Rh. palmatum a~*(8.602 7-8.770 0), b~*(27.534 8-28.968 6), and Rh. officinale a~*(6.825 7-7.464 3),b~*(21.001 6-27.716 4). According to this study, rank correlation analysis and Fisher discriminant analysis are feasible to distinguish the base of Rhei Radix et Rhizoma in a certain range, and provide some theoretical basis for the identification of Rhei Radix et Rhizoma. It also provides a new method and idea for the identification of other multi-base Chinese medicine.

Assessment of the burden of clonorchiasis and its temporal changes in China / 中国血吸虫病防治杂志

Objective To assess the burden of clonorchiasis and identify its temporal and spatial changes in China, thus to provide insights into the control and prevention of the diseases. Methods The disability-adjusted life years (DALYs) was employed as the primary indicator for the disease burden. The prevalence data of Clonorchis sinensis infection were obtainted from the three national surveys on important human parasitic diseases in China, conducting during the period from 1988 to 1922, from 2001 to 2004 and from 2014 to 2016, respectively, and the demographic data from National Bureau of Statistics of China. DALYs of clonorchiasis were calculated and the temporal changes were analyzed at both national and provincial levels, using the disability weight (DW) obtained from a community study in China. Sensitivity analysis was carried out to compare the resulted DALYs of China calculated under the method adopted in this study and that calculated with other commonly used methods. Results The national burden of clonorchiasis was 489174.04 [95% confidence interval (CI): (391648.87, 597509.87)] DALYs in China in 2016, indicating 0.36 [95% CI: (0.28, 0.43)] DALYs per 1 000 populations. The regions with a high burden of clonorchiasis were concentrated in southern China and northeastern China, and the provinces with the three highest burdens of clonorchiasis included Guangxi Zhuang Autonomous Region, Guangdong Province and Heilongjiang Province, which accounted for 91.18% of total burdens of clonorchiasis in China. During the periods of the three national surveys on important human parasitic diseases in China, the national burden of clonorchiasis was found to show a tendency of first rise and then decrease in China; however, the burden of clonorchiasis has recently shown a tendency towards a rise in Guangxi Zhuang Autonomous Region, Heilongjiang Province and Jiangxi Province. Sensitivity analysis showed that the calculation of diseases burden with age-stratified prevalence of clonorchiasis was similar to that of our method without age stratification; however, the burden estimates calculated only based on the DW of the severe symptoms were much lower than our estimates. Conclusions The burden of clonorchiasis is high in China, with a large regional difference. Recently, the overall burden of clonorchiasis has shown a tendency of decline in China; however, there is a tendency towards a rise in some provinces. Therefore, the control of clonorchiasis requires more adaptations to local circumstances.
