Simulated weightlessness led to the transformation of glycolipid metabolism in the livers of mice / La antigravedad simulada provocó la transformación del metabolismo de los glicolípidos en el hígado de ratones / Antigravidade simulada levou à transformação do metabolismo de glicolipídios no fígado de camundongos

ABSTRACT Objectives: The effects of weightlessness on the liver were studied using a tail suspension (TS) male mouse model. Methods: The effects of 0-, 2- and 4-week TS (CON, TS2 and TS4 groups) on glycogen and lipid content, as well as on the molecular processes of the synthesis and degradation pathways, were examined. Results: (1) The number of glycogenosomes under ultrastructure and the glycogen content were considerably larger in the TS4 group than in the other two groups. (2) In the TS4 group, glycogen synthase activity remained constant while glycogen phosphorylase activity dropped, indicating that glycogen breakdown was reduced. (3) The livers of the TS2 group had the highest lipid and triglyceride content, indicating lipid buildup in the liver at this time. (4) In the TS2 group, the activities of the fatty acid synthesis-related factors acetyl-CoA carboxylase and fatty acid synthase increased, while hepatic lipase decreased, indicating that lipid synthesis increased, while decomposition decreased. (5) In the TS2 group, the protein expression of glucose transporters 1 and 2 increased. Conclusions: From TS2 weeks to TS4 weeks, the main energy consumption mode in the livers of mice transitioned from glucose metabolism to lipid metabolism as glucose use decreased. Level of evidence II; Comparative prospective study.

RESUMEN Objetivos: Se estudiaron los efectos de la antigravedad en el hígado utilizando un modelo de ratón macho en prueba de suspensión de la cola (TS, tail suspension). Métodos: Se examinaron los efectos de la TS a las 0, 2 y 4 semanas (grupos CON, TS2 y TS4) sobre el contenido de glucógeno y lípidos, así como sobre los procesos moleculares de las vías de síntesis y degradación. Resultados: (1) El número de glucogenosomas ultraestructurales y el contenido de glucógeno fueron expresivamente más altos en el grupo TS4 que en los otros dos grupos. (2) En el grupo TS4, la actividad de la glucógeno sintasa se mantuvo constante, mientras que la actividad de la glucógeno fosforilasa disminuyó, lo que indica que la degradación del glucógeno se redujo. (3) Los hígados del grupo TS2 presentaron el mayor contenido de lípidos y triglicéridos, lo que indica la acumulación de lípidos en el hígado en ese momento. (4) En el grupo TS2, la actividad de los factores relacionados con la síntesis de ácidos grasos acetil-CoA carboxilasa y ácido graso sintasa aumentó, mientras que la lipasa hepática disminuyó, indicando que la síntesis de lípidos aumentó mientras que la descomposición disminuyó. (5) En el grupo TS2, la expresión proteica de los transportadores de glucosa 1 y 2 aumentó. Conclusiones: Desde la semana TS2 hasta la semana TS4, el principal modo de consumo de energía en el hígado de los ratones pasó del metabolismo de la glucosa al metabolismo de los lípidos a medida que disminuía el uso de la glucosa. Nivel de Evidencia II, Estudio retrospectivo comparativo.

Novel PAX9 compound heterozygous variants in a Chinese family with non-syndromic oligodontia and genotype-phenotype analysis of PAX9 variants

Abstract Studies have reported that >91.9% of non-syndromic tooth agenesis cases are caused by seven pathogenic genes. Objective To report novel heterozygous PAX9 variants in a Chinese family with non-syndromic oligodontia and summarize the reported genotype-phenotype relationship of PAX9 variants. Methodology We recruited 28 patients with non-syndromic oligodontia who were admitted to the Hospital of Stomatology Hebei Medical University (China) from 2018 to 2021. Peripheral blood was collected from the probands and their core family members for whole-exome sequencing (WES) and variants were verified by Sanger sequencing. Bioinformatics tools were used to predict the pathogenicity of the variants. SWISS-MODEL homology modeling was used to analyze the three-dimensional structural changes of variant proteins. We also analyzed the genotype-phenotype relationships of PAX9 variants. Results We identified novel compound heterozygous PAX9 variants (reference sequence NM_001372076.1) in a Chinese family with non-syndromic oligodontia: a new missense variant c.1010C>A (p.T337K) in exon 4 and a new frameshift variant c.330_331insGT (p.D113Afs*9) in exon 2, which was identified as the pathogenic variant in this family. This discovery expands the known variant spectrum of PAX9; then, we summarized the phenotypes of non-syndromic oligodontia with PAX9 variants. Conclusion We found that PAX9 variants commonly lead to loss of the second molars.

Objective @#To investigate the feasibility of epidural catheters in parotid gland duct anastomosis and the function of the affected side gland after parotid gland duct anastomosis. @* Methods@# Thirteen patients who were treated in the Department of Oral and Maxillofacial Surgery of Xuzhou Central Hospital using an epidural catheter as the scaffold for parotid gland catheter anastomosis were enrolled from Jan. 2019 to June 2021. The swelling, salivary fistula and catheter patency in the parotid gland area were evaluated two weeks after the operation. 99mTcO4- single photon emission computed tomography (SPECT) was used for quantitative detection of salivary gland secretion function@*Results@# Thirteen patients had no swelling or salivary fistula in the parotid gland area of the affected side two weeks after the operation, and the catheter secretion was unobstructed. There was no significant difference in the uptake rate between the parotid gland on the affected side and the parotid gland on the healthy side (t = -0.859, P = 0.399), and there was no significant difference in the excretion rate between the parotid gland on the affected side and the parotid gland on the healthy side (t = 0.693, P = 0.495). The parotid gland excretion function of the affected side was excellent three months after the operation.@*Conclusion @#Parotid duct anastomosis with an epidural catheter as the stent has good feasibility, and parotid gland secretion function recovers well after the operation, which is worthy of clinical application.

Refractory pneumoparotid in children: a case report and literature review / 口腔疾病防治

Objective @#To discuss the treatment of pneumoparotid and to provide a reference for clinical practice. @*Methods@# A case of refractory pneumoparotid was reported, and the diagnosis and treatment of parotid emphysema were reviewed and analyzed in combination with the literature.@*Results @#This child had parotid gland enlargement without any obvious cause for more than 1 month. Conservative treatment, such as anti-inflammatory agents, psychological interventions and physical compression were ineffective. The patient had a history of cerebral palsy with epilepsy and involuntary cheek bulging behavior. Therefore, we considered it a refractory case. It was cured after parotid duct ligation and partial parotidectomy of the superficial lobe. A literature review showed that a pneumoparotid is a rare parotid enlargement. Most of the clinical cases were considered to be caused by the return of air into the parotid gland through the parotid duct due to an increase in oral pressure. The diagnosis of pneumoparotid mainly depends on intermittent parotid gland swelling and other clinical manifestations and imaging examination methods, such as ultrasound, CT, MRI and angiography. Its treatment mainly includes conservative anti-inflammatory treatment, physical therapy and psychological intervention. Surgical treatment is indicated for refractory parotid emphysema.@*Conclusion@# Pneumoparotid cases may further develop into parotid inflammation, which is generally treated conservatively. For some severe, recurrent and poor compliance cases, surgical treatment is sometimes needed.

Nomogram for predicting post-traumatic hydrocephalus after decompressive craniectomy for traumatic brain injury

SUMMARY OBJECTIVE: This study aimed to develop and validate a practical nomogram to predict the occurrence of post-traumatic hydrocephalus in patients who have undergone decompressive craniectomy for traumatic brain injury. METHODS: A total of 516 cases were enrolled and divided into the training (n=364) and validation (n=152) cohorts. Optimal predictors were selected through least absolute shrinkage and selection operator regression analysis of the training cohort then used to develop a nomogram. Receiver operating characteristic, calibration plot, and decision curve analysis, respectively, were used to evaluate the discrimination, fitting performance, and clinical utility of the resulting nomogram in the validation cohort. RESULTS: Preoperative subarachnoid hemorrhage Fisher grade, type of decompressive craniectomy, transcalvarial herniation volume, subdural hygroma, and functional outcome were all identified as predictors and included in the predicting model. The nomogram exhibited good discrimination in the validation cohort and had an area under the receiver operating characteristic curve of 0.80 (95%CI 0.72-0.88). The calibration plot demonstrated goodness-of-fit between the nomogram's prediction and actual observation in the validation cohort. Finally, decision curve analysis indicated significant clinical adaptability. CONCLUSION: The present study developed and validated a model to predict post-traumatic hydrocephalus. The nomogram that had good discrimination, calibration, and clinical practicality can be useful for screening patients at a high risk of post-traumatic hydrocephalus. The nomogram can also be used in clinical practice to develop better therapeutic strategies.

Ossification of bilateral stylohyoid ligament with Bell facial paralysis: a case report and literature review / 口腔疾病防治

Objective @# investigate the correlation between the ossification of the styloid hyoid ligament and Bell’s facial paralysis and provide a reference for clinical diagnosis and treatment.@* Methods@# A case of ossification of the bilateral stylohyoid ligament with Bell's facial palsy caused by ossification of the bilateral stylohyoid ligament was diagnosed by clinical manifestations, differential diagnosis and imaging examination. The surgical plan was determined, and combined surgical resection of the ossified area of the styloid hyoid ligament and the greater horn of the hyoid was performed. Postoperative cefoxitin sodium anti-inflammatory treatment, methylprednisolone hormone treatment, acyclovir antiviral treatment, mecobalamin nutritional neurotherapy, and the relevant literature were analyzed. @* Results@# The patient experienced pain when swallowing before surgery, disappearance of right frontal ridges, incomplete eyelid closure, and ptosis of mouth corners. An MRI scan of the brain excluded intracranial space-occupying lesions and resulted in the diagnosis of Bell’s facial paralysis. High-resolution CT of the styloid process confirmed ossification of the styloid hyoid ligament. Styloid process shortening and partial hyoid resection were performed under general anesthesia. Half a month after discharge, the symptoms of sore throat and pain in swallowing disappeared, facial nerve function recovered well, right eyelid closure function recovered well, and right mouth droop improved. The facial nerve function basically returned to normal after 1 month of follow-up. A review of the relevant literature showed that ossification of the stylohyoid ligament to form pseudojoint dilation can locally stimulate the peripheral facial nerve and lead to facial paralysis symptoms. @*Conclusion@# Ossification of the styloid hyoid ligament is usually characterized by pharyngeal pain, which can be confirmed by imaging examination. Ossification of the styloid hyoid ligament with facial paralysis is rare in the clinic, so it is necessary to make a clear diagnosis and treat the symptoms.

@#Abstract: Objective　To study the characteristics and diagnostic efficacy of Rose-Bengal plate agglutination test (RBPT), standard-tube agglutination test (SAT) and enzyme-linked immunosorbent assay (ELISA) in the diagnosis of brucellosis. Methods　A total of 489 suspected brucellosis patients with complete records, who admitted to Xing'anmeng People's Hospital from March 2020 to May 2021, were selected as the subjects. The diagnostic value of SAT, RBPT and ELISA for brucellosis was analyzed with exposure history + clinical symptoms + serological test/brucellosis isolation and culture as the gold standard. Results　Of the 489 suspected patients, 183 (37.42%) were diagnosed with brucellosis, while 234 (47.85%), 148 (30.27%) and 195 (39.88%) were positive by RBPT, ELISA and SAT, respectively. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of RBPT in the diagnosis of brucellosis were 95.08%, 80.39%, 74.36%, 96.47%, and 85.89%, respectively; the values of the above parameters for ELISA were 78.69%, 98.69%, 97.30%, 88.56%, and 91.21%, respectively; those values of SAT were 98.36%, 95.10%, 92.31%, 98.98%, and 96.32%, respectively. The sensitivity of RBPT was significantly higher than ELISA, but the specificity and accuracy were significantly lower than ELISA (all P<0.05). The sensitivity and accuracy of SAT diagnosis were significantly higher than ELISA, but the specificity was significantly lower than ELISA (all P<0.05). There was no significant difference between SAT and RBPT in the sensitivity of diagnosis, but the specificity and accuracy were significantly higher than those of RBPT (P<0.05). Conclusion　RBPT and SAT have high sensitivity in diagnosis of brucellosis, while ELISA has high specificity in diagnosis. RBPT with high sensitivity and convenient operation can be used for primary screening in field detection, and then the other two methods can be used for rechecking, so as to further improve the efficiency and accuracy of diagnosis of brucellosis.

Host-schistosome interactions mediated by cross-species microRNA / 中国热带医学

@#Abstract: Schistosomiasis is a serious major parasitic disease that threatens human life and health. A better understanding of the mechanism of host-schistosome interactions is the key to designing new prevention and control strategies. MicroRNAs (miRNAs) are endogenous small non-coding RNA molecules, which lead to the degradation of the target messenger RNA (mRNA) or inhibition of its translation in a sequence-specific manner. Both schistosome and its host produce miRNAs, which can be secreted by extracellular vesicles (EVs). There is accumulating evidence that miRNAs from schistosome can be taken up by host cells, and finely manipulate the phenotype of host cells for their survival or pathogenesis in a cross-species manner, even inhibiting the growth and metastases of hepatoma cells. It is still unknown whether host free miRNAs can be taken up by schistosome, but this phenomenon is highly probable. miRNA-mediated cross-species regulation has emerged as a novel mechanism for host-schistosome interactions, and this review summarizes the advances in this regard.

A total of 56 dyslexia group (group DD), attention deficit hyperactivity disorder group (group ADHD), comorbidity group and normal control group were selected and compared the differences of their visual motor integration ability and related factors ability. Multiple linear regression analysis was used to explore the predictive effects of related factors on visual motor integration ability.@*Results@#The scores of visual integration ability and visual perception in comorbidity group (95.05±14.01, 12.71±7.40) were lower than those in DD group (104.77±17.19，23.04±11.48), ADHD group (104.00±14.11，25.70±10.74) and normal control group (129.80±12.91, 44.05±16.56) ( F/Z =58.24,110.49, P <0.05). The visual working memory score of the comorbidity group ( 73.64 ±5.36) was lower than the normal control group (78.96±4.68) ( P <0.05)，and there was no significant difference between the DD group (74.48±7.06) and the ADHD group (75.98±7.36) ( P >0.05). The results of multiple regression showed that visual perception, age, IQ and visual working memory were associated with visual and motor integration ability of dyslexia children with ADHD ( R 2=0.32，0.17，0.11， 0.04 ， P <0.05).@*Conclusion@#Visual motor integration and visual perception among children with DD combined ADHD are more severely impaired than those with ADHD and DD alone. Visual perception, age, IQ and visual working memory could help predict the development of visual and motor integration ability in children with DD combined ADHD.

Ulinastatin alleviates early brain injury after intracerebral hemorrhage by inhibiting oxidative stress and neuroinflammation via ROS/MAPK/Nrf2 signaling pathway

Purpose: Spontaneous intracerebral hemorrhage (ICH) is still a major public health problem, with high mortality and disability. Ulinastatin (UTI) was purified from human urine and has been reported to be anti-inflammatory, organ protective, and antioxidative stress. However, the neuroprotection of UTI in ICH has not been confirmed, and the potential mechanism is unclear. In the present study, we aimed to investigate the neuroprotection and potential molecular mechanisms of UTI in ICH-induced early brain injury in a C57BL/6 mouse model. Methods: The neurological score, brain water content, neuroinflammatory cytokine levels, oxidative stress levels, and neuronal damage were evaluated. Results: UTI treatment markedly increased the neurological score, alleviated brain edema, decreased the levels of the inflammatory cytokines tumor necrosis factor-α (TNF-α), interleukin-1ß (IL-1ß), IL-6, and NF-κB, decreased the levels of reactive oxygen species (ROS) and malondialdehyde (MDA), and upregulated the levels of glutathione (GSH), superoxide dismutase (SOD), and Nrf2. This finding indicated that UTI-mediated inhibition of neuroinflammation and oxidative stress alleviated neuronal damage after ICH. The neuroprotective capacity of UTI is partly dependent on the ROS/MAPK/Nrf2 signaling pathway. Conclusions: UTI improves neurological outcomes in mice and reduces neuronal death by protecting against neural neuroinflammation and oxidative stress.
