ABSTRACT

ABSTRACT Spinal cord ischemia due to decreased cord perfusion is a devastating complication in patients with thoracoabdominal dissection following frozen elephant trunk (FET) repair surgery. However, rare occurrence of spinal cord ischemia leading to paraplegia after long-term follow-up of FET repair has been reported. Here, we describe a case of spinal cord ischemia resulting in paraplegia nine years after hybrid total arch repair with FET. Cerebrospinal fluid drainage and serial treatment were utilized to decrease intraspinal pressure and increase blood flow to the spinal cord. Three months after the onset of paraplegia and with treatment and rehabilitation, the patient recovered to walk.

ABSTRACT

Objective:To observe the impact of core stability training in the sling exercise therapy pattern on the balance of stroke survivors.Methods:Sixty stroke survivors were randomly divided into a control group ( n=30) and an experimental group ( n=30). In addition to routine rehabilitation training, the control group received traditional core stability training, while the experimental group underwent core stability training applying the sling exercise therapy pattern. Before and after 4 weeks of training, the standing balance of both groups was evaluated using the Prokin balance trainer, with the length and area of motion recorded when performing the balance test with the eyes open and closed. Surface electromyography was used to record the average EMG (AEMG) values of the bilateral erector spinae and multifidus muscles during the balance testing. Results:After the 4 weeks of training the length and the area of progression of the center of the pressure were both significantly smaller for both groups than before the training with the eyes both open and closed. The average length and area in the experimental group were significantly less than among the controls. The AEMG values recorded during the balance tests were significantly higher than those before the intervention for both groups, with the multifidus muscle averages on the affected side significantly greater in the experimental group than among the controls when performing the balance test with the eyes closed.Conclusion:Core stability training in the sling exercise therapy pattern is superior to conventional core stability training because it can better improve the balance of stroke survivors.

ABSTRACT

To explore the relationship between the early or delayed age at natural menopause and metabolic syndrome (MS) in women. A total of 4 734 natural menopausal women who completed the baseline survey from November 2017 to January 2020 in the Guangzhou Middle-aged and Elderly Chronic Disease Prospective Cohort Study were selected in this cross-sectional study. Data on general demographic characteristics, disease history and female physiological health indicators were collected. Logistic regression model and restricted cubic spline curve were used to analyze the relationship between the age at natural menopause and MS. The results showed that the mean age of the subjects was (60±6) years old. The median (Q1,Q3) age at natural menopause was 50 (49, 52) years old, and the prevalence of MS was 14.8%(699/4 734). After adjusting for confounders, the age at natural menopause was closely related to MS in an approximate"U"shape. Compared with the group of normal age at natural menopause, the early age at menopause (OR=1.52, 95%CI: 1.12-2.06) and delayed age at menopause (OR=1.77, 95%CI: 1.36-2.30) had a higher risk of MS. In the group with time since menopause ≤6 years and 7-9 years, the risk of MS in the group with delayed age at menopause was 2.40 times (95%CI: 1.54-3.75) and 2.19 times (95%CI: 1.11-4.31) higher than that in the group with normal menopausal age, respectively. In conclusion, the early and delayed age at natural menopause increased the risk of MS. The increased risk of MS in delayed age at natural menopause mainly occurred within 10 years since menopause.

ABSTRACT

Variations in the dynein axonemal heavy chain gene, dynein axonemal heavy chain 6 (DNAH6), lead to multiple morphological abnormalities of the flagella. Recent studies have reported that these deficiencies may result in sperm head deformation. However, whether DNAH6 is also involved in human acrosome biogenesis remains unknown. The purpose of this study was to investigate DNAH6 gene variants and their potential functions in the formation of defective sperm heads and flagella. Whole-exome sequencing was performed on a cohort of 375 patients with asthenoteratozoospermia from the First Affiliated Hospital of Anhui Medical University (Hefei, China). Hematoxylin and eosin staining, scanning electron microscopy, and transmission electron microscopy were performed to analyze the sperm morphology and ultrastructure. Immunofluorescence staining and Western blot analysis were conducted to examine the effects of genetic variants. We identified three novel deleterious variants in DNAH6 among three unrelated families. The absence of inner dynein arms and radial spokes was observed in the sperm of patients with DNAH6 variants. Additionally, deficiencies in the acrosome, abnormal chromatin compaction, and vacuole-containing sperm heads were observed in these patients with DNAH6 variants. The decreased levels of the component proteins in these defective structures were further confirmed in sperm from patients with DNAH6 variants using Western blot. After intracytoplasmic sperm injection (ICSI) treatment, the partner of one patient with a DNAH6 variant achieved successful pregnancy. Overall, novel variants in DNAH6 genes that contribute to defects in the sperm head and flagella were identified, and the findings indicated ICSI as an effective clinical treatment for such patients.

ABSTRACT

Objective:To confirm the mechanism of Sedum alfredii extract (SafE) alleviating radiation injury in human small intestinal epithelial cells (HIEC-6). Methods:HIEC-6 cells were divided into 4 groups, including control group (Con), irradiation group (IR), SafE alone group (SafE) and SafE plus irradiation group (SafE+ IR). All of the SafE groups were treated with 0.02 g/ml (W/V) SafE for 24 h. Cell viability (CCK-8 method ) and intracellular ROS levels were investigated at 24 h after 2, 4, and 6 Gy irradiation. Samples were taken at 24 h after 4 Gy irradiation for transcriptome analysis, and the intracellular E3 ubiquitin ligase PRKN expression level was measured. The thickness of endoplasmic reticulum was detected at 24 h after 4 Gy irradiation using fluorescent dye.Results:SafE could maintain cell viability after irradiation ( t=2.94-10.40, P<0.05), and significantly reduced the level of ROS in the irradiated cells ( t=-13.29--4.53, P<0.05). PRKN was preliminarily verified to be the target gene of SafE that maintained PRKN transcript level and endoplasmic reticulum thickness after irradiation (IR group vs. Con group: t=-5.55, 3.27, P<0.05, SafE group vs. SafE+ IR group: P>0.05). Conclusion:SafE is effective in maintaining ER thickness and reducing cellular radiation damage and its target gene PRKN could be regulated by ionizing radiation.

ABSTRACT

In mammals, the piezoelectric protein, Prestin, endows the outer hair cells (OHCs) with electromotility (eM), which confers the capacity to change cellular length in response to alterations in membrane potential. Together with basilar membrane resonance and possible stereociliary motility, Prestin-based OHC eM lays the foundation for enhancing cochlear sensitivity and frequency selectivity. However, it remains debatable whether Prestin contributes to ultrahigh-frequency hearing due to the intrinsic nature of the cell's low-pass features. The low-pass property of mouse OHC eM is based on the finding that eM magnitude dissipates within the frequency bandwidth of human speech. In this study, we examined the role of Prestin in sensing broad-range frequencies (4-80 kHz) in mice that use ultrasonic hearing and vocalization (to >100 kHz) for social communication. The audiometric measurements in mice showed that ablation of Prestin did not abolish hearing at frequencies >40 kHz. Acoustic associative behavior tests confirmed that Prestin-knockout mice can learn ultrahigh-frequency sound-coupled tasks, similar to control mice. Ex vivo cochlear Ca2+ imaging experiments demonstrated that without Prestin, the OHCs still exhibit ultrahigh-frequency transduction, which in contrast, can be abolished by a universal cation channel blocker, Gadolinium. In vivo salicylate treatment disrupts hearing at frequencies <40 kHz but not ultrahigh-frequency hearing. By pharmacogenetic manipulation, we showed that specific ablation of the OHCs largely abolished hearing at frequencies >40 kHz. These findings demonstrate that cochlear OHCs are the target cells that support ultrahigh-frequency transduction, which does not require Prestin.

ABSTRACT

The ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry(UPLC-Q-TOF-MS~E) technology was employed to compare the chemical components between the aerial and underground parts of Coptis chinensis samples from different batches. According to the retention time, molecular ion peak, and LC-MS~E fragment information of the reference substances and available literature, we identified a total of 40 components. Thirty-three and 31 compounds were respectively identified in the underground part(taproots) and the aerial part(stems and leaves) of C. chinensis. Among them, 24 compounds, including alkaloids(e.g., berberine and jatrorrhizine) and phenolic acids(e.g., chlorogenic acid, quinic acid, and tanshinol), were common in the two parts. In addition, differential components were also identified, such as magnoline glucoside in the underground part and(±) lariciresionol-4-β-D-glucopyranoside in the aerial part. The analysis of fragmentation pathways based on spectra of reference substances indicated the differences among samples of different batches. Furthermore, we performed the principal component analysis(PCA) for the peak areas of C. chinensis in different batches. The results showed that the underground part and the aerial part were clearly clustered into two groups, indicating that the chemical components contained in the two parts were different. Furthermore, the results of partial least squares discriminant analysis(PLS-DA) identified 31 differential compounds(VIP value>1) between the underground part and the aerial part, mainly including alkaloids, phenolic acids, lignans, and flavonoids. This study proves that C. chinensis possesses great development potential with multiple available compounds in stems and leaves. Moreover, it sheds light on for the development and utilization of non-medicinal organs of C. chinensis and other Chinese medicinal herbs.

Objective:To control the quality of the reference sample of Wenjingtang by establishing the specific chromatograms. Method:On the basis of analyzing 15 batches of Wenjingtang freeze-dried powder samples, a high performance liquid chromatography (HPLC) specific chromatogram analysis method of Wenjingtang was established. The system adaptability was investigated and the retention time, relative retention value and deviation caused by different chromatographic columns and instruments were calculated by using the same brand of chromatographic columns, four different brands of chromatographic columns and instruments from three different manufacturers. The precision, repeatability and stability of this method was further completed. The possible chemical components of the freeze-dried powders were speculated and identified by ultra-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry (UPLC-Q-TOF-MS<italic><sup>n</sup></italic>). Chromatographic separation was performed on ACQUITY UPLC BEH C<sub>18</sub> column (2.1 mm×100 mm, 1.7 μm) with acetonitrile (A)-0.1% formic acid aqueous solution (B) as mobile phase for gradient elution (0-2.8 min, 10%A; 2.8-8.0 min, 10%-18%A; 8.0-12.2 min, 18%-25%A; 12.2-15.3 min, 25%-40%A; 15.3-17.4 min, 40%A; 17.4-20.5 min, 40%-90%A), and column temperature was set at 30 ℃ with flow rate of 0.4 mL·min<sup>-1</sup>. Mass spectrometry was performed on electrospray ionization, data were collected under positive and negative ion modes, and the detection range was <italic>m</italic>/<italic>z</italic> 50-1 600. Result:Ten characteristic peaks were selected as the distinguishing features in this specific chromatograms, and eight of them were identified by comparing with the reference standards, including paeoniflorin (peak 1), liquiritin apioside (peak 2), liquiritin (peak 3), ferulic acid (peak 4), iquiritigenin (peak 6), cinnamaldehyde (peak 8), paeonol (peak 9)and glycyrrhizic acid (peak 10). By mass spectrometry analysis, 30 compounds were identified, and the source of medicinal materials were assigned. It mainly contained triterpenoid saponins and flavonoids from Glycyrrhizae Radix et Rhizoma, ginsenosides from Ginseng Radix et Rhizoma, monoterpenoid glycosides and tannins from Paeoniae Radix Alba, steroids in Achyranthis Bidentatae Radix, phenolic acids in Angelicae Sinensis Radix. Conclusion:The established characteristic chromatographic analysis method of Wenjingtang is simple, stable and repeatable. The chemical composition of the freeze-dried powder of Wenjingtang is basically defined by mass spectrometry identification and source attribution, which can provide reference for the development and quality control of Wenjingtang in the future.

ABSTRACT

The present study determined the quantitative markers of total proanthocyanidins in the purification of the industrial waste Choerospondias axillaris pericarp based on the comparison results of high-performance liquid chromatography(HPLC) and mass spectrometry(MS) and optimized the purification process with two stable procyanidins as markers. The adsorption and desorption of five different macroporous adsorption resins, the static adsorption kinetics curve of NKA-Ⅱ resin, the maximum sample load, and the gradient elution were investigated. The UPLC-Q-TOF-MS/MS was employed for qualitative analysis of the newly-prepared total proanthocyanidins of C. axillaris pericarp. As revealed by the results, NKA-Ⅱ resin displayed strong adsorption and desorption toward total proanthocyanidins. The sample solution(50 mg·mL~(-1)) was prepared from 70% ethanol crude extract of C. axillaris pericarp dissolved in water and 7-fold BV of the sample solution was loaded, followed by static adsorption for 12 h. After 8-fold BV of distilled water and 6-fold BV of 10% ethanol were employed to remove impurities, the solution was eluted with 8-fold BV of 50% ethanol, concentrated, and dried under reduced pressure, and purified total proanthocyanidin powder was therefore obtained. Measured by vanillin-hydrochloric acid method, the purity and transfer rate of total proanthocyanidins were 47.67% and 59.92%, respectively, indicating the feasibi-lity of the optimized process. UPLC-Q-TOF-MS/MS qualitative analysis identified 16 procyanidins in C. axillaris total proanthocyanidins. The optimized purification process is simple in operation and accurate in component identification, and it can be applied to the process investigation of a class of components that are difficult to be separated and purified. It can also provide technical support and research ideas for the comprehensive utilization of industrial waste.

ABSTRACT

Objective:To investigate the value of chest CT quantitative index in clinical classification and lung injury severity evaluation of COVID-19.Methods:The current study retrospectively analyzed the clinical and CT data of 438 patients with COVID-19 between January 2020 and March 2020 in Tongji Hospital, Tongji Medical College, Huazhong University of Science & Technology. The clinical types included common type ( n=146), severe type ( n=247) and critical type ( n=45). The chest CT indexes of all patients were quantitatively analyzed by artificial intelligence (AI) deep learning, including whole lung volume, CT lung opacification, ground glass opacification volume (GGO volume; CT value<-300 HU), solid opacification volume (SO volume; CT value ≥-300 HU) and the ratio of volume to the whole lung volume, the ratio of SO volume to GGO volume (SO volume/GGO volume). Kruskal-Wallis test was used to conduct statistical analysis of the differences in quantitative parameters among clinical types, and multiple ordered logistic regression was used to analyze the correlation between quantitative parameters and clinical types. Results:Among the 438 patients diagnosed with COVID-19, severe and critical patients were older ( P<0.05), and most of the critical patients were male ( P<0.05). The main clinical manifestations of all clinical types were fever, followed by cough, fatigue, chest tightness, dyspnea, gastrointestinal symptoms and so on. GGO volume was the main CT manifestation of all the three clinical subtypes. The whole-lung opacification volume, GGO volume, SO volume and their proportions in whole-lung volume significantly increased from common, severe to critical types (all P<0.05). SO volume/GGO volume increased with the severity of clinical type [common type 0.12 (0.03, 0.34), severe type 0.29 (0.11, 0.59), critical type 0.61 (0.39, 0.97)]. Multiple ordered logistic regression analysis showed that whole-lung opacification volume (OR=1.009), SO volume/GGO volume (OR=1.866), GGO volume (OR=1.008) and SO volume (OR=1.016) had a significant positive effect on the severity of clinical typing ( P<0.01). Conclusion:Quantitative indicators of chest CT based on deep learning algorithm (SO volume, GGO volume, SO volume/GGO volume) are closely related to the clinical severity of COVID-19.

ABSTRACT

Background@#Postherpetic neuralgia (PHN) is the most common complication of acute herpes zoster. The treatment of PHN remains a challenge for clinical pain management. Despite the effectiveness of anticonvulsants, antidepressants, and lidocaine patches in reducing PHN, many patients still face intractable pain disorders.In this randomized controlled study, we evaluated whether hydromorphone through intravenous patient-controlled analgesia (IV PCA) was effective in relieving PHN. @*Methods@#Patients with PHN were randomly divided into two groups, one group received oral pregabalin with IV normal saline, another group received oral pregabalin with additional IV PCA hydromorphone for two weeks. Efficacy was evaluated at 1, 4, and 12 weeks after the end of the treatments. @*Results@#Two hundred and one patients were followed up for 12 weeks. After treatment, numerical rating scale (NRS) score of patients in the hydromorphone group was significantly lower than that of the control group, and the difference of NRS scores between the two groups was statistically significant at 4 and 12 weeks after treatment. The frequency of breakthrough pain in the hydromorphone group was significantly lower than that in the control group 1 and 4 weeks after treatment.After treatment, the quality of sleep in the hydromorphone group was significantly improved compared with the control group. The most common adverse reactions in the hydromorphone group were dizziness and nausea, with no significant respiratory depression. @*Conclusions@#IV PCA hydromorphone combined with oral pregabalin provides superior pain relief in patients with PHN, which is worthy of clinical application and promotion.

ABSTRACT

Objective:To evaluate the effect of using a walking support band on the gait of stroke survivors.Methods:Sixty stroke survivors were randomly divided into a walking support band group ( n=20), an ankle foot orthosis (AFO) group ( n=20) and a conventional rehabilitation group ( n=20). All three groups received conventional rehabilitation therapy, while the AFO group members were additionally provided with an ankle-foot orthosis and the walking support band group members received training wearing a walking support band. Before and after 4 weeks of treatment, all three groups were evaluated using three-dimensional gait analysis. Results:A total of 57 patients finished the study. After the interventions, the average step speed, frequency and step length of the three groups had all increased significantly, while the average stride width, the percentage of double stance phase, unaffected and affected side stance phase, and the ratio between unaffected and affected side stance phase had all decreased significantly. After the intervention, the average step speed, frequency and length of the AFO and walking support band groups had increased significantly compared with the conventional rehabilitation group, while the average stride width of the AFO group, and the stride width, the percentage of double stance phase and unaffected side stance phase of the walking support band group had decreased significantly. After the treatment, the average percentages of double stance phase and unaffected side stance phase of the walking support band group had decreased significantly more than in the AFO group.Conclusions:A walking support band can significantly improve the abnormal gait of stroke survivors and is superior to an ankle-foot orthosis when combined with conventional rehabilitation therapy.

ABSTRACT

A girl, aged 12 years, was admitted due to fever and rash for 3 days. The child developed recurrent high fever and rash on both lower extremities 3 days before, and the rash on left lower extremity quickly merged into a patch within 24 hours, with hemorrhage and necrosis in black and purple, large vesicles, and blisters in the center. Laboratory examination showed a reduction in platelet count and significant increases in fibrinogen and D-dimer during the course of the disease. The child was diagnosed with purpura flulminans. She was given meropenem combined with linezolid for anti-infection, injection of gamma globulin for immunoregulation, and low-molecular-weight heparin for anticoagulation. The fluid in the rash blisters was drawn and the wound was treated to prevent infection. The child's temperature returned to normal, with improvement in gangrene. She was discharged after platelet count, fibrinogen, and D-dimer had returned to normal. Purpura fulminans is a rare thrombotic hemorrhagic disease with rapid progression and is commonly seen in children. Without timely treatment, it may cause severe sequelae with high disability and mortality rates. Anti-infection, correction of coagulation function, and local management of gangrene skin are of great importance during treatment.

ABSTRACT

ObjectiveTo investigate the expression of CD90 in human intrahepatic cholangiocellular carcinoma and its association with lymph node metastasis and poor prognosis. MethodsA total of 49 samples of intrahepatic cholangiocellular carcinoma tissue and 49 samples of adjacent tissue were collected after surgical resection in The Affiliated Hospital of Chengde Medical College from March 2013 to March 2016, and 40 normal liver tissue samples were selected as control. Immunohistochemistry was used to measure the expression of CD90 in each sample, and its association with clinical indices, survival, and prognosis of patients with intrahepatic cholangiocellular carcinoma was analyzed. The t-test was used for comparison of continuous data between two groups; the chi-square test was used for comparison of categorical data between two groups, the Kruskal-Wallis H test was used for comparison between three groups and further comparison between two groups. The Kaplan-Meier curve was used to analyze postoperative recurrence and survival, and the log-rank test was used for comparison. Results The moderately positive expression rate of CD90 was 65.31% in intrahepatic cholangiocellular carcinoma tissue, 30.61% in adjacent normal tissue, and 0% in normal liver tissue, suggesting that the intrahepatic cholangiocellular carcinoma tissue had a significantly higher moderately positive expression rate of CD90 than adjacent normal tissue and normal liver tissue (P<0.05). The expression of CD90 was associated with TNM stage and hilar lymph node metastasis in the patients with intrahepatic cholangiocellular carcinoma (χ2=12837 and 17.824, both P<0.001). The patients with negative/weakly positive expression of CD90 had significantly higher relapse-free survival rate and overall survival rate after surgery than those with moderately/strongly positive expression (χ2=3.845 and 4.152, P=0025 and 0.021). ConclusionCD90 is highly expressed in human intrahepatic cholangiocellular carcinoma tissue, which is associated with hilar lymph node metastasis and poor prognosis and plays an important role in tumor development, progression, and metastasis.
