ABSTRACT
BACKGROUND: Pleural effusion caused by fibrosing mediastinitis is rarely reported. This study aimed to summarize the clinical manifestations, diagnosis and treatment of transudative pleural effusion due to fibrosing mediastinitis. METHODS: Medical records and follow-up data of 7 patients with transudative pleural effusion due to fibrosing mediastinitis in Beijing Chaoyang Hospital between May 2014 and Feb 2018 were retrospectively analyzed. RESULTS: These patients included 4 males and 3 females, with an average age of (64 ± 9) years. There were 3 left-sided effusions, 2 right-sided effusions and 2 bilateral effusions. Previous or latent tuberculosis was found in 6 patients. Pulmonary hypertension was indicated by echocardiography in all the 7 patients. Computed tomography pulmonary angiography (CTPA) of all the 7 cases showed increased soft tissue images visible in the mediastinum and bilateral hilus, different degrees of stenosis or occlusion in the pulmonary artery and pulmonary vein. In addition, 4 cases were found of right middle lobe atelectasis with a mediastinal window setting. There was interstitial pulmonary edema on the side of pleural effusion with a lung window setting. All the 7 patients were treated with intermittent drainage of pleural effusion combined with diuretic therapy. Five patients were treated with antituberculosis therapy. Up to now, two patients died of right heart failure and respiratory failure after 2 and 16 months respectively; The remaining 5 patients were still in follow up. CONCLUSION: Fibrosing mediastinitis can lead to pulmonary vein stenosis or occlusion, and thus cause transudative pleural effusion, which can be detected by CTPA. Pulmonary hypertension, long time of cough, and a history of tuberculosis are common in these patients. The common therapy is intermittent drainage of pleural effusion combined with diuretic therapy.

OBJECTIVES: To investigate the ultrasound (US) characteristics of metastatic malignancies (MM) in the major salivary glands and to assess the diagnostic value of the close relationship with the glandular capsule in identifying MM. METHODS: From January 2016 and April 2022, 122 patients with major salivary gland malignancies, including 20 patients with MM and 102 patients with primary malignancies (PM) confirmed by histopathological examination, were enrolled in this study. Their clinicopathologic and US data were recorded and analyzed. The diagnostic performance of the close relationship with the glandular capsule for differentiating MM from PM was analyzed. RESULTS: The mean age of MM were older than that of PM (59.50 ± 14.57 vs. 49.96 ± 15.73, p = 0.013). Compared with PM patients, MM were associated with a higher prevalence of local pain symptoms (p = 0.007) and abnormal facial nerve function (p < 0.001). MM were also more frequently characterized by unclear borders, rough margins, irregular shapes, heterogeneous internal echos, absence of cystic areas, presence of calcifications, close relationship with the glandular capsule, and US-reported positive cervical lymph nodes (all p < 0.05). The close relationship with the glandular capsule showed to be a good indicator in distinguishing between MM and PM, with an area under the receiver operating characteristic curve of 0.863, a sensitivity of 100%, a specificity of 72.5%, and an accuracy of 92.2%. Positive and negative predictive were calculated at 41.7% and 100%, respectively. CONCLUSIONS: The US finding of a close relationship with the glandular capsule is a highly sensitive diagnostic indicator for MM. Following this finding, US-guided needle biopsy should be recommended to further confirm the diagnosis.
ABSTRACT
ABSTRACT: We aimed to develop and validate a nomogram based on conventional ultrasound (CUS) radiomics model to differentiate radial scar (RS) from invasive ductal carcinoma (IDC) of the breast. In total, 208 patients with histopathologically diagnosed RS or IDC of the breast were enrolled. They were randomly divided in a 7:3 ratio into a training cohort (n = 145) and a validation cohort (n = 63). Overall, 1316 radiomics features were extracted from CUS images. Then a radiomics score was constructed by filtering unstable features and using the maximum relevance minimum redundancy algorithm and the least absolute shrinkage and selection operator logistic regression algorithm. Two models were developed using data from the training cohort: one using clinical and CUS characteristics (Clin + CUS model) and one using clinical information, CUS characteristics, and the radiomics score (radiomics model). The usefulness of nomogram was assessed based on their differentiating ability and clinical utility. Nine features from CUS images were used to build the radiomics score. The radiomics nomogram showed a favorable predictive value for differentiating RS from IDC, with areas under the curve of 0.953 and 0.922 for the training and validation cohorts, respectively. Decision curve analysis indicated that this model outperformed the Clin + CUS model and the radiomics score in terms of clinical usefulness. The results of this study may provide a novel method for noninvasively distinguish RS from IDC.

OBJECTIVES: Preoperative identification of different stromal subtypes of pleomorphic adenoma (PA) of the salivary gland is crucial for making treatment decisions. We aimed to develop and validate a model based on histogram analysis (HA) of ultrasound (US) images for predicting tumour stroma ratio (TSR) in salivary gland PA. METHODS: A total of 219 PA patients were divided into low-TSR (stroma-low) and high-TSR (stroma-high) groups and enrolled in a training cohort (n = 151) and a validation cohort (n = 68). The least absolute shrinkage and selection operator regression algorithm was used to screen the most optimal clinical, US, and HA features. The selected features were entered into multivariable logistic regression analyses for further selection of independent predictors. Different models, including the nomogram model, the clinic-US (Clin + US) model, and the HA model, were built based on independent predictors using logistic regression. The performance levels of the models were evaluated and validated on the training and validation cohorts. RESULTS: Lesion size, shape, cystic areas, vascularity, HA_mean, and HA_skewness were identified as independent predictors for constructing the nomogram model. The nomogram model incorporating the clinical, US, and HA features achieved areas under the curve of 0.839 and 0.852 in the training and validation cohorts, respectively, demonstrating good predictive performance and calibration. Decision curve analysis and clinical impact curves further confirmed its clinical usefulness. CONCLUSIONS: The nomogram model we developed offers a practical tool for preoperative TSR prediction in PA, potentially enhancing clinical decision-making.

OBJECTIVES: Accurate distinguishing between immunoglobulin G4-related sialadenitis (IgG4-RS) and primary Sjögren syndrome (pSS) is crucial due to their different treatment approaches. This study aimed to construct and validate a nomogram based on the ultrasound (US) scoring system for the differentiation of IgG4-RS and pSS. METHODS: A total of 193 patients with a clinical diagnosis of IgG4-RS or pSS treated at our institution were enrolled in the training cohort (n = 135; IgG4-RS = 28, pSS = 107) and the validation cohort (n = 58; IgG4-RS = 15, pSS = 43). The least absolute shrinkage and selection operator regression algorithm was utilized to screen the most optimal clinical features and US scoring parameters. A model for the differential diagnosis of IgG4-RS or pSS was built using logistic regression and visualized as a nomogram. The performance levels of the nomogram model were evaluated and validated in both the training and validation cohorts. RESULTS: The nomogram incorporating clinical features and US scoring parameters showed better predictive value in differentiating IgG4-RS from pSS, with the area under the curves of 0.947 and 0.958 for the training cohort and the validation cohort, respectively. Decision curve analysis demonstrated that the nomogram was clinically useful. CONCLUSIONS: A nomogram based on the US scoring system showed favourable predictive efficacy in differentiating IgG4-RS from pSS. It has the potential to aid in clinical decision-making.

OBJECTIVES@#To observe the effects of electroacupuncture (EA) at "Neiguan" (PC 6) and "Zusanli"(ST 36) on the gastric emptying rate, the level of serotonin (5-HT) and the protein expression of motilin (MTL), ghrelin, substance P (SP) and vasoactive intestinal peptide (VIP) in the antral tissue of the rats with functional dyspepsia (FD) and explore the effect mechanism of EA in treatment of FD.@*METHODS@#A total of 21 SPF male SD rat pups were randomly divided into a normal group, a model group and an EA group, with 7 rats in each group. In the model group and the EA group, FD model was prepared by the gavage with 0.1% sucrose iodoacetamide solution combined with the modified small platform method. After the successful modeling, EA was applied to "Neiguan" (PC 6) and "Zusanli"(ST 36) in the rats of the EA group, with disperse-dense wave, 20 Hz/100 Hz in frequency, stimulated for 30 min, once daily, for 7 days consecutively. Before and after intervention, the general condition of the rats was observed in each group. After the completion of intervention, the gastric emptying rate was measured, the morphological changes of gastric antral tissue were observed using HE staining, the level of 5-HT was detected with ELISA method, and the protein expression of MTL, ghrelin, SP, and VIP was determined with Western blot method in the antral tissue of rats.@*RESULTS@#In the normal group, the rats were in a good mental state, with lustrous fur, flexible movement and the increase of food intake and body mass. In the model group, the rats were poor in mental state, lack of lustre in fur, preference for the body curled up, reduced activity and response; and a part of rats had loose stool, obviously enlarged gastric body and gastric food retention. In the EA group, the general condition of rats, e.g. the mental state, food intake and activity, were improved, the gastric body got smaller obviously and the gastric food retention was reduced when compared with the model group. The antral structure was intact, the glands were rich and no injury of the gastric mucosa was found, e.g. inflammatory reaction and edema in the rats of each group. Compared with the normal group, the gastric emptying rate was decreased (P<0.01), 5-HT level was increased (P<0.01), the protein expression of MTL and ghrelin was reduced (P<0.01) and that of VIP was elevated (P<0.01) in the rats of the model group. The gastric emptying rate was increased (P<0.01), 5-HT level was decreased (P<0.01), and the protein expression of MTL and ghrelin was elevated (P<0.05, P<0.01) in the rats of the EA group when compared with those in the model group.@*CONCLUSIONS@#Electroacupuncture at "Neiguan" (PC 6) and "Zusanli"(ST 36) may effectively relieve gastric dysfunction, strengthen gastric motility and promote gastric emptying so as to alleviate the symptoms of dyspepsia in FD rats, and its mechanism may be related to the regulation of gastrointestinal hormones in the antral tissue.

OBJECTIVE@#This study explored the rejuvenation mechanisms of Thai polyherbal medicines using different approaches, including in vitro methods, as well as a well-defined nematode model, Caenorhabditis elegans.@*METHODS@#THP-R-SR012 decoction was selected from 23 polyherbal medicines, based on metal-chelating and chain-breaking antioxidant capacities. The influences of this extract on the survival and some stress biomarkers of C. elegans under paraquat-induced oxidative stress were evaluated. Furthermore, lifespan analysis and levels of lipofuscin accumulation were examined in senescent nematodes. The phytochemical profile of THP-R-SR012 was analyzed.@*RESULTS@#Supplementation with THP-R-SR012 decoction significantly increased the mean lifespan and reduced the oxidative damage to C. elegans under oxidative stress conditions. Further, THP-R-SR012 supplementation slightly influenced the lifespan and the level of lipofuscin accumulation during adulthood. Antioxidant-related phytochemical constituents of THP-R-SR012 decoction were rutin, naringenin, 3,4-dihydroxybenzoic acid, gallic acid, glycyrrhizic acid, demethoxycurcumin and 18α-glycyrrhetinic acid.@*CONCLUSION@#The antioxidant potential of THP-R-SR012 was due to its scavenging properties, its enhancement of antioxidant-related enzyme activities, and the presence of the antioxidant-related compound. These results support the traditional use of THP-R-SR012 decoction as a tonic for nourishing and strengthening the whole body.

Objective:To optimize the topological design of locking plate for distal radial fracture so that the internal fixation stiffness can be customized.Methods:Models of both the distal radial fracture and the conventional locking plate fixation were constructed using software for three-dimensional modeling and computer-aided design. Based on the data from our previous finite element analysis, a decrease of 33.33% in axial stiffness but retention of more than 90.00% in torsional stiffness were defined as the optimization limits. The conventional plate was redesigned by way of topological optimization iterations. Finite element analysis was done to compare stiffness and interfragmentary strain (IFS) between the new optimized design and conventional design of the locking plate under both compressive and torsional loads.Results:The axial stiffness of the optimized plate was 636.5 N/mm with a downgrading magnitude of 19.7% which was close to the given limit; the torsional stiffness was 634.12 Nmm/° with a downgrading magnitude of 8.8% which remained under the given limit. In the optimized design, a more significant increase was observed in axial IFS than that in shear IFS, leading to a similar effect as the stiffness regulation did.Conclusion:The optimized design of locking plate for distal radial fracture can provide a reliable solution for customized regulation of the internal fixation stiffness.
ABSTRACT
On the base of the idea of traditional Chinese medicine as "disease prevention", the mode and the protocol of the moxibustion intervention for the group under quarantine after close contact with coronavirus disease 2019 (COVID-19) were explored. The group under quarantine after close contact with COVID-19 was taken as the subjects. By the non-contact physician-patient communication network platform co-developed by China Association of Acupuncture-Moxibustion, Hunan Provincial Association of Acupuncture-Moxibustion, Data Center of China Academy of Chinese Medical Sciences and Yuge Medicine Company, an exploratory randomized controlled trial was designed. A total of 100 cases were included and randomized into a moxibustion group and a conventional intervention group, 50 cases in each one. In the moxibustion group, moxibustion intervention was used. In the conventional intervention group, the conventional observation was adopted without moxibusiton intervention applied. The outcomes included the symptoms changes, e.g. anxiety, emotional disturbance, fatigue, headache and diarrhea, as well as whether quarantine release and the case confirmed or not, etc. The results were evaluated before intervention, in 14 days of intervention and 2 weeks after intervention separately. In this research, on the base of internet plus technology and with the internet communication platform adopted, through mobile phone WeChat App, it was to implement the subject screen, the random allocation and the instruction of moxibustion intervention as well as the quality control of patient's diary and data collection. It is anticipated that the significance and the implementation mode of moxibustion intervention can be assessed preliminarily for the group under quarantine after close contact with COVID-19.

Objective·To amplify the interferon regulator factor 3 (IRF3) short hairpin RNA (shRNA) virus and investigate the effect of the virus on the nuclear expression of Irak1bp1 protein in lipopolysaccharide (LPS)-stimulated Raw 264.7 cells. Methods?·?Adenovirus was amplified in HEK293T cells and the virus titer was detected by TCID 50 assay. The Raw 264.7 cells were randomly divided into four groups including adenovirus (-) LPS (-) group, adenovirus (-) LPS (+) group, adenovirus (+) LPS (-) group and adenovirus (+) LPS (+) group. The expression of intracellular IRF3 mRNA was detected by real-time PCR, and the nuclear expression of IRF3 and Irak1bp1 protein were detected by Western blotting. Results?·?The titer of adenovirus was 2.2×1011PFU/mL and the best MOI was 300. The expression of IRF3 mRNA and nuclear IRF3 protein in LPS-stimulated Raw 264.7 cells were significantly higher than those of the control group. The cellular constitutive expression of IRF3 at mRNA level and the LPS-induced expression of IRF3 were significantly inhibited after transfection of Raw 264.7 cells with adenovirus strains carrying IRF3 shRNA. However, the nuclear constitutive expression of IRF3 protein was not affected by IRF3 shRNA in the unstimulated state. The expression of nuclear Irak1bp1 protein was significantly higher than that of the control group. The nuclear constitutive expression and the LPS-induced expression of Irak1bp1 protein were not affected by IRF3 shRNA. Conclusion?·?Transfection of LPS-stimulated Raw 264.7 cells with adenovirus strains carrying IRF3 shRNA could effectively inhibit the expression of IRF3, but not affect the nuclear expression of Irak1bp1 protein.
ABSTRACT
Objective To compare cortical bone screwing and Endobutton plating for the treatment of ankle joint fracture complicated with injury to the distal tibiofibular syndesmosis. Methods Fifty-eight pa-tients with ankle joint fracture and injury to the distal tibiofibular syndesmosis were treated at Department of Orthopedic Surgery, The Affiliated Hospital to Guangdong Medical University from January 2014 to June 2016. Half of them were treated by conventional cortical bone screwing. They were 16 males and 13 females with an average age of 43.2 ± 4.1 years. The other half were treated by Endobutton plating. They were 15 males and 14 females with an average age of 44.1 ± 3.9 years. The 2 groups were compared in terms of intraoperative bleed-ing, operation time, tibiofibular clear space ( TBCS ) , tibiofibular overlap ( TBOL ) , the American Orthopedic Foot Ankle Society (AOFAS) ankle-hindfoot scale and complications. Results The cortical bone screwing group needed significantly shorter operation time (63.4 ± 5.4 min) than the plating group (89.6 ± 6.2 min) ( P <0.05) . There were no significant differences between the 2 groups in intraoperative bleeding ( 68.9 ± 6.3 mL versus 67.4 ± 6.4 mL ) , TBCS ( 4.6 ± 0.3 mm versus 4.7 ± 0.3 mm) , TBOL ( 7.5 ± 0.4 mm versus 7.4 ± 0.4 mm ) , good to excellent rate by AOFAS score ( 72.4% versus 75.9%) , or rate of complications ( 6.9% versus 10.3%) ( P > 0.05 ). Conclusion Since cortical bone screwing and Endobutton plating show no signifi-cant difference for the treatment of ankle joint fracture complicated with distal tibiofibular syndesmosis injury, a proper surgical procedure should be decided according to the specific conditions of the patient.

Objective:To observe the clinical effect of wheat grain-sized cone moxibustion combined with fire needle therapy in the treatment of dorsal wrist ganglion (DWG). Methods:A total of 63 patients with DWG were randomized into a treatment group (n=32) and a control group (n=31). Cases in the control group were treated with fire needle therapy. Based on the therapy given to the control group, cases in the treatment group were additionally given wheat grain-sized cone moxibustion therapy. Then the therapeutic efficacies and recurrence rate were evaluated. Results:After treatment, the overall effective rate was 93.8% in the treatment group, versus 77.4% in the control group, and the between-group comparison showed a statistical significance (P<0.05); 6 months after the treatment, the recurrence rate in the treatment group was obviously lower than that in the control group (P<0.05). Conclusion:The long-term and short-term effects of wheat grain-sized cone moxibustion combined with fire needle therapy in the treatment of DWG are better than those of fire needle therapy alone, and therefore, worth popularizing.
ABSTRACT
Based on the understanding of TCM and western medicine on diabetes mellitus (DM) and diabetic peripheral neuropathy (DPN), the relationship between DPN pathogenesis and blood stasis of TCM is discussed from the perspective of modern medicine. It is indicated blood stasis is the key pathogenesis to DPN, and a two-step acupuncture treatment of DPN from the theory of blood stasis is proposed. The first step is to analyze the pathogenesis of blood stasis, which could block the progress of the disease and diminish the symptoms. The second step is to apply acupuncture for pathological result of blood stasis by following the principle of, as a result, the purpose of treating both symptoms and root cause is achieved.

ABSTRACT
Objective:To investigate the effects of moxibustion on the serum metabolism in healthy human body based on the 1H nuclear magnetic resonance (1H NMR) metabolomics technology, and to find the differences in metabolites, as well as to elucidate the effects of moxibustion on healthy human body from the viewpoint of global metabolism. Methods:Sixty subjects of healthy young men from the enrolled students were randomly divided into a moxibustion group and a control group using random number table, with 30 cases in each group. Subjects in the moxibustion group accepted mild moxibustion on the right Zusanli (ST 36), once a day, 15 min for each time, and continuous treatment for 10 d; those in the control group did not receive any intervention. There were 28 cases in the moxibustion group and 23 cases in the control group after interventions. On the 1st day, 5th day and 10th day of the intervention, serum samples were collected from subjects of the two groups, and metabolic spectra were obtained by the1H NMR technology. Results: Before and after the intervention, serum1H NMR of the moxibustion group was significantly different, while the difference was insignificant in the control group. Metabolite changes in the moxibustion group were mainly in low density lipoprotein (LDL)/very low density lipoprotein (VLDL), valine, isoleucine, leucine, lactic acid, glutamine, citric acid, polyunsaturated fatty acids, creatine, glycine, glycerol, glucose, tyrosine, histidine, formic acid, alanine, lysine, acetic acid, and glutamic acid. Conclusion:Moxibustion can cause changes of serum metabolic patterns in healthy human by influencing the concentrations of branched-chain amino acids, polyunsaturated fatty acids, and other metabolites to strengthen body's metabolisms of amino acids and fatty acid.
