Objective: To clarify the long-term characteristics of tinnitus following treatment of sudden deafness and its long-term physical and mental effects on patients. Methods: A retrospective analysis was performed on 88 patients (46 males and 42 females; Age from 11 to 89 years) with sudden deafness treated in Department of Otoscope Surgery of Peoples's Libration Army General Hospital in Beijing from April 2020 to January 2021, and the occurrence of tinnitus and treatment effect of all patients were analyzed. Follow-up was conducted for patients with residual tinnitus after treatment for more than 1 year by the investigation and filling in the survey information collection form, Tinnitus Evaluation Questionnaire (TEQ) and Tinnitus Handicap Inventory (THI). Descriptive statistics and SPSS 22.0 software were used for statistical data analysis. Results: In this study, 93.2% (82/88) of patients with sudden deafness were accompanied by tinnitus at the onset, and the proportion of long-term tinnitus after treatment was 90.2% (74/82). After 1 year of treatment for sudden deafness, the improvement of tinnitus was significant in low-frequency sudden deafness compared with those of high-frequency, flat and total deafness sudden deafness (χ2 value was 6.801, 4.568 and 4.038, all P<0.05). In patients with residual tinnitus, 9 (12.2%) patients felt minimal loudness or even no loudness, 34 (46.0%) patients felt slight loudness, 28 (37.8%) patients felt tinnitus was relatively loud, and 3 (4.1%) patients felt tinnitus was loud or noisy. Nine (12.2%) patients's sleep was often affected, 41 (55.4%) patients's sleep was sometimes affected, 9 (12.2%) patients's sleep was rarely affected, 15 (20.3%) patients's sleep was almost not affected. Twenty-eight (37.8%) patients basically completely adapted to tinnitus and 46 (62.2%) patients did not completely adapted to residual tinnitus. Eight (10.8%) patients had no impact on life, 39 (52.7%) patients had slight impact, 22 (29.7%) patients had moderate impact, and the other 5 (6.8%) patients had greater impact. According to tinnitus evaluation questionnaire(TEQ), there were 12 cases (16.2%) of grade Ⅰ, 26 cases (35.1%) of grade Ⅱ, 28 cases (37.8%) of grade Ⅲ, 7 cases (9.5%) of grade Ⅳ and 1 case (1.4%) of grade Ⅴ. According to tinnitus handicap inventory(THI), tinnitus disability was classified into grade Ⅰ, 22 cases (29.7%), grade Ⅱ, 14 cases (18.9%), Grade Ⅲ, 27 cases (36.5%) and grade Ⅳ, 11 cases (14.9%). Conclusion: The rate of residual tinnitus following treatment of sudden deafness is high. Some of the patients can completely adapt residual tinnitus after one year, but some of them will be affected when sleep, work and study. Residual tinnitus can lead to tinnitus disability in different degrees.

Conclusion:RASAL3 is up-regulated in human cholangiocarcinoma, which can promote the occurrence and development of cholangiocarcinoma by activating FXYD6 and affecting Na +-K +-ATPase activity.

Effectiveness and safety of acupuncture for treating functional constipation: An overview of systematic reviews / 中西医结合学报

BACKGROUND@#Functional constipation (FC) is one of the most prevalent functional gastrointestinal disorders. Dissatisfaction with medications prescribed to treat FC may lead patients to seek alternative treatments. Numerous systematic reviews (SRs) examining the use of acupuncture to treat FC have reported inconsistent results, and the quality of these studies has not been fully evaluated.@*OBJECTIVE@#In this overview, we evaluated and summarized clinical evidence on the effectiveness and safety of acupuncture for treating FC and evaluated the quality and bias of the SRs we reviewed.@*SEARCH STRATEGY@#The search strategy was structured by medical subject headings and search terms such as "acupuncture therapy" and "functional constipation." Electronic searches were conducted in eight databases from their inception to September 2020.@*INCLUSION CRITERIA@#SRs that investigated the effectiveness and safety of acupuncture for managing FC were included.@*DATA EXTRACTION AND ANALYSIS@#Two authors independently extracted information and appraised the methodology, reporting accuracy, quality of evidence, and risk of bias using the following critical appraisal tools: (1) A Measurement Tool to Assess Systematic Reviews 2 (AMSTAR 2); (2) Risk of Bias in Systematic Reviews (ROBIS); (3) Preferred Reporting Items for Systematic Reviews and Meta-analyses for Acupuncture (PRISMA-A); and (4) the Grading of Recommendations, Assessment, Development and Evaluations (GRADE). A κ index was used to score the level of agreement between the 2 reviewers.@*RESULTS@#Thirteen SRs that examined the clinical utility of acupuncture for treating FC were identified. Using the AMSTAR 2 tool, we rated 92.3% (12/13) of the SRs as "critically low" confidence and one study as "low" confidence. Using the ROBIS criteria, 38.5% (5/13) of the SRs were considered to have "low risk" of bias. Based on PRISMA-A, 76.9% (10/13) of the SRs had over 70% compliance with reporting standards. The inter-rater agreement was good for AMSTAR 2, ROBIS, and PRISMA-A. Using the GRADE tool, we classified 22.5% (9/40) of the measured outcomes as "moderate" quality, 57.5% (23/40) as "low" quality, and 20.0% (8/40) as "very low" quality. The inter-rater agreement was moderate when using GRADE. Descriptive analyses indicated that acupuncture was more efficacious than sham acupuncture for improving weekly complete spontaneous bowel movements (CSBMs) and for raising the Bristol Stool Form Scale (BSFS) score. Acupuncture appeared to be superior to anti-constipation drugs for improving weekly spontaneous bowel movements, the total effective rate, and the Patient Assessment of Constipation Quality of Life score. Although ten SRs mentioned the occurrence of adverse events, serious adverse events were not associated with acupuncture treatment.@*CONCLUSION@#Acupuncture may be more efficacious than sham acupuncture for improving CSBMs and BSFS scores and may be superior to anti-constipation drugs for improving bowel movement frequency, as well as quality of life. Limitations to current studies and inconsistent evidence suggest a need for more rigorous and methodologically sound SRs to draw definitive conclusions.@*SYSTEMATIC REVIEW REGISTRATION@#PROSPERO CRD42020189173.

Self-assembled aggregations in Coptidis Rhizoma decoction dynamically regulate intestinal tissue permeability through Peyer's patch-associated immunity / 中草药·英文版

Objective: To investigate the dynamic regulation of self-assembled aggregations (SAA) in Coptidis Rhizoma decoction on the permeability of intestinal tissue and the mechanism underlying. Methods: The effects of SAA on berberine (Ber) absorption were respectively analyzed in an in situ intestinal perfusion model and in an Ussing Chamber jejunum model with or without Peyer's patches (PPs). The expression levels of ZO-1, Occludin and Claudin-1 were detected by immunofluorescence to evaluate the tight junction (TJ) between intestinal epithelium cells. The expression levels of T-box-containing protein expressed in T cells, signal transducers and activators of tranion-6, retinoic acid receptor-related orphan receptor γt and forkhead box P3 in PPs were detected by the reverse transcription-polymerase chain reaction and the secretions of interferon-γ (IFN-γ), interleukin-4 (IL-4), interleukin-17 (IL-17) and transforming growth factor-β (TGF-β) in PPs were evaluated by immunohistochemistry, to reflect the differentiation of T lymphocyte in PPs to helper T (Th) cell 1, Th2, Th17 and regulatory T (Treg) cell. To confirm the correlation between SAA in Coptidis Rhizoma decoction, PPs-associated immunity and intestinal epithelium permeability, SAA were administrated on an Ussing Chamber jejunum model with immunosuppressed PPs and evaluated its influences on intestinal tissue permeability and TJ proteins expression. Results: SAA in Coptidis Rhizoma decoction could dose-dependently promote Ber absorption in jejunum segment, with the participation of PPs. The dose-dependent and dynamical regulations of SAA on permeability of intestinal tissue and TJ proteins expression level between intestinal epithelium cells occurred along with the dynamically changed T lymphocyte differentiation and immune effectors secretion in PPs. The administration of SAA on immunosuppressed PPs exhibited dose-dependent PPs activation, inducing dynamic promotion on intestinal tissue permeability and inhibition on TJ proteins expression. Conclusion: SAA can improve the Ber absorption in small intestine, through the PPs-associated immunity induced dynamic regulation on intestinal tissue permeability and TJ proteins expression. These findings might enlighten the research of traditional Chinese medicine decoction.

In Vivo Detection of Lipid-Core Plaques by Coronary CT Angiography: A Head-to-Head Comparison with Histologic Findings

200 µm, a circumference > 60 degrees, and a cap thickness < 450 µm. The percentage distributions of CT pixel attenuation ≤ 20, 30, 40, and 50 HU were calculated using quantitative histogram analysis.RESULTS: A total of 271 transverse sections were co-registered between CCTA and pathological analysis. Overall, 26 lipid cores and 16 fibrous plaques were identified by pathological analysis. There was no significant difference in median CT attenuation between the lipid and fibrous plaques (51 HU [interquartile range, 46–63] vs. 57 HU [interquartile range, 50–64], p = 0.659). The median percentage of CT pixel attenuation ≤ 30 HU accounted for 11% (5–17) of lipid-core plaques and 0% (0–2) of fibrous plaques (p < 0.001). The sensitivity and specificity of the method for diagnosing lipid plaques by the average CT pixel attenuation ≤ 30 HU were 80.8% and 87.5%, respectively. The area under the receiver operator characteristics curve was 0.898 (95% confidence interval: 0.765–0.970; 3.0% was the best cut-off value). The diagnostic performance was significantly higher than those of the average pixel CT attenuation percentages ≤ 20, 40, and 50 HU and the mean CT attenuation (p < 0.05).CONCLUSION: In in vivo conditions, with the pathological lipid core as the gold standard, quantification of the percentage of average CT pixel attenuation ≤ 30 HU in the histogram can be useful for accurate identification of lipid plaques.

The regulation of gonadal somatic cell differentiation during sex determination in mice / 生理学报

In mammals, the gonad is composed of germ cells and somatic cells. The gonads have the potential of bidirectional differentiation before sex determination. The differentiation of somatic cells in the gonad determines the development of testis or ovary, and this process is regulated by many factors. SRY, SOX9, SOX3, SOX8, SOX10, FGF9/FGFR2, PGD2, AMH, and DMRT1 are involved in the differentiation of testis. By contrast, FOXL2, CTNNB1, RSPO1, WNT4, Follistatin, ERα/β, and BMP2 play important roles in ovary development. If these molecular regulatory networks are damaged by endogenous or exogenous factors, disorders of sex differentiation, even sex reversal, will occur. In this review, the regulation of somatic cell fate during gonad primordium formation and sex determination in mouse model was discussed.

Trimetazidine reduces formation of neutrophil extracellular traps via inhibiting autophagy / 中国药理学通报

Aim To study the effects of trimetazidine (TMZ)on theformationof neutrophil extracellular traps (NETs) induced by oxidized low-density lipoprotein (ox-LDL) in vitro and its relationship associated with cell autophagy. Methods The bone marrow neutrophils of mice were extracted by density gradient centrifugation,and NETs induction model was established using ox-LDL. Furthermore, TMZ, autophagy inhibitor LY294002 and autophagy inducer Rapamycin were added to disturb the induction of NETs induced by ox-LDL. The production of NETs marker MPO-DNA and the content of cfDNA/nets in the supernatantwere observed. Meanwhile, Western blot was employed to determine the protein expression of myeloperoxidase (MPO),beclin-l and LC3b in neutrophils. Results Treatment of ox-LDL to adhered neutrophils could lead to the formation of extracellular MPO-DNA and cfDNA/nets generation in a time-and concentration-dependent manner. The protein expression of LC3b,beclin-1 and MPO in neutrophils was up-regulated after treatedwith ox-LDL. TMZ pretreatment significantly inhibited NETs release and reduced the protein expression of LC3b,beclin-1 and MPO in neutrophils,which could be simulated by PI3K/AKT pathway blocker LY294002, while AKT/mTOR inhibitor rapamycin preconditioning did the opposite. Conclusions Ox-LDL-induces the formation of NETs in a time-and concentration-dependent manner. TMZ could down-regulate the level of autophagy and neutrophils, inhibit the induction of ox-LDL on NETs and reduce the release of NETs.

Advance in Aromatase Inhibitor Related Arthralgias (review) / 中国康复理论与实践

Estrogen deficiency, inflammatory reactions, metabolic disorders, etc., are considered to be possible mechanisms leading to arthralgias (or joint pain) associated with aromatase inhibitors (AIs) in breast cancer patients. The use of exercise and other non-pharmacological means (such as vitamin D, Omega-3 fatty acids, acupuncture, etc.) may relieve AIs-related arthralgia, and exercise may play a direct or indirect role to deal with the related pathogenesis. But the results of the studies are still controversial.

Aim To investigate the expression of CAR-MA3, NF-κB in hepatocellular carcinoma tissues and the underlying mechanism of sodium aescinate in inhib-iting the proliferation of human hepatocellular carcino-ma cells. Methods The expression of CARMA3 and NF-κB in HCC tissues were detected by tissue microar-ray immunohistochemistry. MTT was used to determine the effect of sodium aescinate on the proliferation of HCC cells. Cell apoptosis was detected by flow cytom-etry. The expression of CARMA3, NF-κB protein in HepG2 and Hep3B cells treated with sodium aescinate was detected by Western blot and cell immunofluores-cence. Results Tissue microarray analysis showed that the expression of CARMA3 in HCC was up-regulated compared with the adjacent adjacent liver tissues, and the histopathological differentiation, TNM stage, tumor volume and prognosis were correlated. Sodium aesci-nate in 40 μmol·L-1concentration ( IC50) inhibited the growth of HCC cell lines, promoting its apoptosis, but without toxic effects on normal liver cells. Western blot and cell immunofluorescence detection of sodium aescinate could significantly inhibit the expression of CARMA3 and NF-κB. Conclusion Sodium aescinate can effectively inhibit the proliferation of HCC cells by inhibiting the activation of CARMA3/NF-κB signaling in HCC.
