Efficacy of rehabilitation physiotherapy combined with brace correction in patients with mild to moderate scoliosis secondary to cerebral palsy.

BACKGROUND: Scoliosis secondary to cerebral palsy is one of the common complications of cerebral palsy in children with cerebral palsy. OBJECTIVE: This study aimed to explore the efficacy of rehabilitation combined with brace correction in patients with scoliosis secondary to cerebral palsy. METHODS: A total of 52 patients with scoliosis secondary to cerebral palsy were selected from our hospital from April 2019 to April 2022 and divided into the control group and experimental group according to the statistical randomization method (n= 26 in each group). Control group: mean age (14.28 ± 2.31) years; 16 males and 10 females. Experimental group: average age (14.24 ± 2.35) years; 15 males and 11 females. The control group wore scoliosis orthopedic brace, while the experimental group was treated with rehabilitation manipulation and rehabilitation training (including gymnastic training and weight training) on the basis of the control group for 1 year. The clinical efficacy of the two groups was compared and observed; the number of degrees of scoliosis (Cobb angle), the angle of vertebral rotation (AVR) and the distance of the parietal vertebrae from the sacral midline (AVT) were compared before and after treatment; the incidence of adverse events during treatment was observed in the two groups. RESULTS: After treatment, both groups showed significant improvement in the overall effectiveness of treatment, Cobb's angle, AVR and AVT compared with those before treatment (P< 0.05). The experimental group had a significantly higher overall effective rate of treatment than the control group (P< 0.05), a significantly smaller Cobb's angle and AVR than the control group (P< 0.05) and a significantly shorter AVT than the control group (P< 0.05). The incidence of adverse events during treatment was lower in both groups and was not significantly different (P> 0.05). CONCLUSION: The combination of rehabilitation physiotherapy and bracing is effective in optimizing the clinical outcome of patients with scoliosis secondary to cerebral palsy, improving their scoliosis dysfunction and providing a high level of safety in treatment.

One-Pot Stereoselective Synthesis of the Naphthofurano-Iminosugars via a [3 + 2] Cycloaddition Reaction.

This study presents the synthesis of novel naphthofurano-iminosugars (4) using 2,3-O-isopropylidene D-ribose tosylate (1a), anilines (2), and 1,4-benzoquinone (3a) as starting materials through key iminium ion/enamine intermediates via [3 + 2] cyclization reactions at room temperature. The reaction has unique regioselectivity and stereoselectivity with moderate to excellent yields. The adaptability of this method has been demonstrated using various substituted anilines, on which both electron-donating and electron-withdrawing groups were well employed in the reactions. Notably, the treatment of the fused multicyclic iminosugar 4 with TFA efficiently leads to an interesting unexpected pyridinium salt (8), possible via four sequential steps: deprotection of the 2,3-O-isopropylidene group, furan ring opening, dehydration condensation of the OH groups, and elimination of water.

Ovarian function in patients with systemic lupus erythematosus: Pathogenesis, drug application and prospective therapies.

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease in which multiple organs are damaged that prevails in fertile women. Currently, glucocorticoids and immunosuppressants are widely used to treat SLE patients. However, ovarian dysfunction occurs following the use of these drugs in women with SLE. Here, we summarize recent progress in terms of understanding ovarian injury, the effects of drug application and strategies to improve ovarian function in women with SLE. This review could be helpful to precisely cure SLE in women desiring to have offspring.

Amphiphilic α-Peptoid-deoxynojirimycin Conjugate-based Multivalent Glycosidase Inhibitor for Hypoglycemic Effect and Fluorescence Imaging.

Multivalent glycosidase inhibitors based on 1-deoxynojirimycin derivatives against α-glucosidases have been rapidly developed. Nonetheless, the mechanism based on self-assembled multivalent glucosidase inhibitors in living systems needs to be further studied. It remains to be determined whether the self-assembly possesses sufficient stability to endure transit through the small intestine and subsequently bind to the glycosidases located therein. In this paper, two amphiphilic compounds, 1-deoxynojirimycin and α-peptoid conjugates (LP-4DNJ-3C and LP-4DNJ-6C), were designed. Their self-assembling behaviors, multivalent α-glucosidase inhibition effect, and fluorescence imaging on living organs were studied. LP-4DNJ-6C exhibited better multivalent α-glucosidase inhibition activities in vitro. Moreover, the self-assembly of LP-4DNJ-6C could effectively form a complex with Nile red. The complex showed fluorescence quenching effect upon binding with α-glucosidases and exhibited potent fluorescence imaging in the small intestine. This result suggests that a multivalent hypoglycemic effect achieved through self-assembly in the intestine is a viable approach, enabling the rational design of multivalent hypoglycemic drugs.

Nucleolus imaging based on naphthalimide derivatives.

Nucleolus was an important cellular organelle. The abnormal morphology and number of the nucleolus have been considered as diagnostic biomarkers for some human diseases. However, the imaging agent based on nucleolus was limited. In this manuscript, a series of nucleolar fluorescent probes based on naphthalimide derivatives (NI-1 âˆ¼ NI-5) had been designed and synthesized. NI-1 âˆ¼ NI-5 could penetrate cell membranes and nuclear membranes, achieve clear nucleolar staining in living cells. These results suggested that the presence of amino groups on the side chains of naphthalimide backbone could enhance the targeting to the cell nucleolus. In addition, the molecular docking results showed that NI-1 âˆ¼ NI-5 formed hydrogen bonds and hydrophobic interactions with RNA, and exhibited enhanced fluorescence upon binding with RNA. These results will provide favorable support for the diagnosis and treatment of nucleolus-related diseases in the future.

Calixarene-based cryoprotectants for ice recrystallization inhibition and cell cryopreservation.

The development of new cryoprotectants for cryopreservation of cells has attracted considerable interest. Herein, five calixarene-based CPAs (SC4A, S-S-C4A, S-SO2-C4A, SBAC4A, and CAC4A) were developed, and their IRI activity, DIS property and cryoprotective effect were studied. SBAC4A with a sulphobetaine zwitterion and SC4A with sulfo group modification possessed better cryoprotective effects than the other calixarene-based CPAs, especially for SBAC4A with the enhanced cell viabilities of 16.16 ± 1.78%, 12.60 ± 1.15% and 14.90 ± 1.66% against MCF-7, hucMSCs and A549 cells, respectively. This result provides a supramolecular principle for developing novel CPAs with consideration of the factors of hydrogen bonding, the macromolecular crowding principle and the three-dimensional (3D) structure.

An alternative route for tricyclic quinazolinone-iminosugars and their glucosidase inhibitory activities.

A series of novel tricyclic quinazolinone-iminosugars 5 and their derivatives 7 were obtained from the tosylated sugars by three steps. Firstly, the reaction of the isopropylidene protected sugar tosylate 1 and o-aminobenzylamine 2 generated the precursor tricyclic quinazolin-iminosuar 3, which was then oxidized by KMnO4 to produce the corresponding quinazolinone 4. Finally, removal of the isopropylidene group yielded the target tricyclic quinazolinone iminosugars 5. In addition, quinazolinone-iminosugars 4ac, 4bc and 4cc who contain bromine in the aromatic region underwent Suzuki reaction with phenylboronic acid, followed with the removal of the isopropylidene group to afford the derivatives 7. This strategy will help to construct such fused multicyclic quinazolinone-iminosugars efficiently. Some compounds show certain inhibition against α-glucosidase (saccharomyce cerevisiae).

This method has high atom and step economy, high stereoselectivity, and gram-scale synthesis (yield 67%).

[Mechanism of Yanghe Decoction against subcutaneous tumor in pulmonary metastasis from breast cancer through HIF-1α signaling pathway regulating glycolysis:based on network pharmacology and animal experiment].

This study aims to explore the mechanism of Yanghe Decoction(YHD) against subcutaneous tumor in pulmonary metastasis from breast cancer, which is expected to lay a basis for the treatment of breast carcinoma with YHD. The chemical components of medicinals in YHD, and the targets of the components were retrieved from Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP) and SwissTargetPrediction. The disease-related targets were searched from GeneCards and Online Mendelian Inheritance in Man(OMIM). Excel was employed to screen the common targets and plot the Venn diagram. The protein-protein interaction network was constructed. R language was used for Gene Ontology(GO) term enrichment and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment. A total of 53 female SPF Bablc/6 mice were randomized into normal group(same volume of normal saline, ig), model group(same volume of normal saline, ig), and low-dose and high-dose YHD groups(YHD, ig, 30 days), with 8 mice in normal group and 15 mice in each of the other groups. Body weight and tumor size was measured every day. Curves for body weight variation and growth of tumor in situ were plotted. In the end, the subcutaneous tumor sample was collected and observed based on hematoxylin and eosin(HE) staining. The mRNA and protein levels of hypoxia inducible factor-1α(HIF-1α), pyruvate kinase M2(PKM2), lactate dehydrogenase A(LDHA), and glucose transporter type 1(GLUT1) were detected by PCR and Western blot. A total of 213 active components of YHD and 185 targets against the disease were screened out. The hypothesis that YHD may regulate glycolysis through HIF-1α signaling pathway to intervene in breast cancer was proposed. Animal experiment confirmed that the mRNA and protein levels of HIF-1α, PKM2, LDHA, and GLUT1 in the high-and low-dose YHD groups were lower than those in the model group. YHD has certain inhibitory effect on subcutaneous tumor in pulmonary metastasis from breast cancer in the early stage, which may intervene pulmonary metastasis from breast cancer by regulating glycolysis through HIF-1α signaling pathway.

A simple ratiometric fluorescent probe for two-photon imaging of carbon monoxide in living cells and zebrafish.

Carbon monoxide (CO) is an important gas signaling molecule and has been widely involved in regulating important life processes. Effective monitoring of CO in living systems is critical. Combined with the accuracy of ratio detection and the advantages of two-photon imaging, a simple ratiometric two-photon fluorescent probe RTFP was rationally designed and synthesized using 7-(diethylamino)-4-hydroxycoumarin as a two-photon fluorophore and allyl carbonate as the reactive unit. Probe RTFP exhibited excellent selectivity and sensitivity towards CO, and was successfully applied to image endogenous CO in living cells and zebrafish.

Rehabilitation Training Can Significantly Increase the Serum IL-11 Levels and Improve the Prognosis in Ischemic Stroke Patients.

We aimed to explore the expression of IL-11 in ischemic stroke patients and its correlation with rehabilitation training and prognosis. The present randomized control study recruited ischemic stroke patients who were admitted during March 2014 to November 2020. All patients underwent computer tomography (CT) and magnetic resonance imaging (MRI) examination. All patients were randomly divided into two groups, including rehabilitation training (RT) group and control group. The patients in the RT group were received rehabilitation training within 2 days after the vital signs were stable while control group received routine nursing. The serum interleukin- (IL-) 11 levels were measured by enzyme-linked immunosorbent assay (ELISA) when patients were just hospitalized and 6 h, 24 h, 48 h, 72 h, and 90 h after treatment. Demographic, clinical statistics, imaging data, and the National Institutes of Health Stroke Scores (NIHSS) were recorded. The modified Rankin Scale (mRS) scores were measured after 90 days treatment to assess the prognosis of ischemic patients. The serum IL-11 levels of the RT group elevated more quickly during the study time compared with the control group. In addition, the NIHSS and mRS scores of ischemic stroke patients in the RT group were significantly lower than that in the control group. The NIHSS score, the proportion receiving rehabilitation training, and the levels of IL-11, triglyceride (TG), and high-density leptin cholesterol (HDLC) of ischemic stroke patients in the mRS score ≥ 3 group were remarkably elevated than that in the mRS score ≤ 2 group. However, the serum IL-11 levels of ischemic stroke patients were obviously decreased in the mRS score ≥ 3 group. IL-11 could be a potential diagnostic biomarker of poor prognosis of ischemic stroke patients. Furthermore, IL-11, NIHSS score, and rehabilitation training were the risk factors for poor prognosis of ischemic stroke patients. This study demonstrated that the ischemic stroke patients in the RT group had higher serum IL-11 levels and better prognosis. This study might provide a new approach to improve the prognosis of patients with ischemic stroke. This trial is registered with ChiCTR-PNR-16007706.

Fluorescence sensing and glycosidase inhibition effect of multivalent glycosidase inhibitors based on Naphthalimide-deoxynojirimycin conjugates.

Synthetic glycoconjugates as chemical probes have been widely developed for the detection of glycosidase enzymes. However, the binding interactions between iminosugar derivatives and glycosidases were limited, especially for the binding interactions between multivalent glycosidase inhibitors and α-glycosidases. In this paper, three naphthalimide-DNJ conjugates were synthesized. Furthermore, the binding interactions and glycosidase inhibition effects of them were investigated. It was found that the strong binding interactions of multivalent glycosidase inhibitors with enzymes were related to the efficient inhibitory activity against glycosidase. Moreover, the lengths of the chain between DNJ moieties and the triazole ring for the naphthalimide-DNJ conjugates influenced the self-assembly properties, binding interactions and glycosidase inhibition activities with multisource glycosidases. Compound 13 with six carbons between the DNJ moiety and triazole ring showed the stronger binding interactions and better glycosidase inhibition activities against α-mannosidase (jack bean) and α-glucosidase (aspergillus niger). In addition, compound 13 showed an effective PBG inhibition effect in mice with 51.18 % decrease in blood glucose at 30 min. This result opens a way for detection of multivalent glycosidase inhibition effect by a fluorescent sensing method.

Elevated Serum Interleukin-17 Levels in Thoracic Trauma Patients with Poor Prognosis: A Prospective Observational Study.

PURPOSE: To measure interleukin (IL)-17 serum levels in thoracic trauma patients and to correlate these levels with other cytokines and with patient prognosis.  Methods: This prospective observational study recruited 130 thoracic trauma patients who were admitted to the Zhoupu Hospital Affiliated to Shanghai Medical College of Health June 2020 to April 2022 and 100 healthy volunteers. Patients were divided into two groups based on Injury Severity Score (ISS): ISS<16 (mild/moderate trauma) and ISS ≥16 (severe trauma). Serum IL-17, tumor necrosis factor α (TNF-α), IL-6, IL-1ß and C-reactive protein (CRP) levels were measured by enzyme-linked immunosorbent assay. Patients with poor prognosis were defined as those who developed serious complications or died during hospitalization or follow-up.  Results: Serum levels of IL-17, TNF-α, IL-6 and IL-1ß were significantly elevated in patients with ISS ≥16 (p<0.05). Serum cytokines levels increased within 48 h in both groups and then gradually decreased during subsequent treatment and rehabilitation. Pearson's analysis indicated a positive correlation among IL-17, TNF-α and IL-1ß. Serum IL-17 levels in patients with poor prognoses were higher than the patients with good prognoses at all time points (p<0.05). Furthermore, for patients with poor prognoses, the serum IL-17 levels had highest diagnostic value among all the cytokines measured. Logistic regression analysis showed that IL-17 was the risk factor for thoracic trauma patients with poor prognoses.  Conclusion: Serum IL-17 levels were significantly elevated in thoracic trauma patients and decreased gradually with rehabilitation. IL-17 was a risk factor for thoracic trauma patients with poor prognoses. This study suggests a new diagnostic and therapeutic target for thoracic trauma patients.

Increased Rates of Health Management and Health Education on Hypertension and Diabetes in Inner Mongolia, China: 10-Year Population Level Trends (2009-2018).

Health management and health education are two important tasks in the national basic public health service project with a wide audience, large service volume, and high accessibility. From 2009 to 2018, the Inner Mongolia Autonomous Region of China launched the basic public health service (BPHS) project comprehensively. The implementation of health management and health education was supported and instructed actively. This study aimed to document population-level trends in health management and health education on chronic diseases such as hypertension and diabetes in Inner Mongolia, China. We collected monthly and annual reports on the implementation progress of the BPHS project in Inner Mongolia, China. A two-stage random sampling method was used to investigate health management and health education for hypertension and diabetes patients. The rate of standard health management for both hypertension and diabetes has significantly increased. The blood pressure control rate and glycemic control rate have also improved. This work provides the most comprehensive evidence to date regarding the upward trends in health management and health education on chronic diseases such as hypertension and diabetes in Inner Mongolia, China.

Identification of the Exercise and Time Effects on Human Skeletal Muscle through Bioinformatics Methods.

Background: The human body has more than 600 kinds of skeletal muscles, which accounts for about 40% of the whole weight. Most skeletal muscles can make bones move, and their strength and endurance directly affect their performance during exercise. Methods: To determine the effects of exercise and time on human skeletal muscle, we downloaded the microarray expression profile of GSE1832 and analyzed it to select differentially expressed genes (DEGs). Then, a protein-protein interaction (PPI) network was established, and the hub genes were identified. Afterwards, DEGs were applied to perform Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis. Finally, with the help of Gene Set Enrichment Analysis (GSEA), the gene sets in the 7 samples were enriched in the KEGG pathway. Results: Through a series of bioinformatics analyses, we obtained a total of 271 DEGs. After that, four hub genes were determined through the PPI network, namely, EP300, STAT1, CDKN1A, and RAC2. In addition, we got that these DEGs were enriched in GO, such as regulation of cell population proliferation, cellular water homeostasis, and so on, and in KEGG, namely, hepatitis B, Epstein-Barr virus infection, small cell lung cancer, pathways in cancer, and others. Finally, the gene set in the samples obtained by GSEA was enriched in the cell cycle, chemokine signaling pathway, DNA replication, cytokine receptor interaction, ECM receptor interaction, and focal adhesion in KEGG. Conclusion: The findings obtained in this study will provide new clues for elucidating the mechanism of exercise and time on human skeletal muscles.

Multivalent glucosidase inhibitors based on perylene bisimide and iminosugar conjugates.

Although multivalent glucosidase inhibitors based on iminosugars have shown enhanced inhibition activity, an effective way to improve their hypoglycemic effect in vivo, is still in infancy and needs further development. In this paper, PBI-5DNJ and PBI-6DNJ, with three or four DNJ moieties respectively conjugated at the bay position were synthesized. PBI-6DNJ evidenced stronger π-π stacking interactions and, when self-assembled, a smaller size than that of PBI-5DNJ. It was found that PBI-6DNJ exhibited superior α-glucosidases (from mice) inhibition activity (Ki = 0.14 ± 0.007 µM) in vitro than that (Ki = 0.31 ± 0.01) of PBI-5DNJ and in vivo hypoglycemic effects in mice models. PBI-6DNJ possessed good hypoglycemic effects with the percentages of PBG levels of 40.40 ± 3.33% and 39.23 ± 4.84% at a dose of 2.0 mg/kg after 15 min and 30 min of administration, respectively. In terms of measuring percentage decrease of PBG level per DNJ unit, PBI-6DNJ displayed a 2.1-fold enhancement than miglitol, demonstrating a consistency between in vitro and in vivo experiments. This paves the way to the connection between in vivo hypoglycemic potency and in vitro glucosidase inhibition assay, leading to reliable and simplified assessment of hypoglycemic potency determination, and opening a basic understanding of the design of multivalent glucosidase inhibitors.

Analysis of the drainage effect of different incisions for high complex anal fistula based on FLUENT hydrodynamic simulation.

Purpose: The biomechanical characteristics of the trauma size and postoperative drainage of different incisions for high complex anal fistula surgery were compared by numerical simulation analysis to provide a theoretical basis for the clinical selection of minimally invasive incisions for surgery. Methods: Using FLUENT finite element software, a typical incision finite element model was established to obtain incision areas, and the total mass outlet flow within 200 s was calculated to evaluate the drainage effect of each incision. Results: The incisions with the largest to smallest areas were the curved, spindle, and curved plus extended groove incision, indicating that the curved plus extended groove incision caused the least damage to the perianal skin muscles. Conversely, the incisions with the largest to smallest total outlet flow were as follows: curved plus extended groove, spindle, curved, and straight incision, suggesting that the curved plus extended groove model had the best diversion effect, and the curved incision had better diversion effect than that of the straight incision. Conclusion: The curved plus extended groove surgical incision had the smallest incision area, minimized damage to the perianal skin and muscle tissue, conformed to the concept of minimally invasive surgery, ensured adequate drainage of exudate, maintained the normal growth of granulation tissue on the wound surface, preserved the original form of the anus, and thus better protected the function of the anus. This improved the quality of life of patients requiring high complex anal fistulas.

Macrocycle molecule-based cryoprotectants for ice recrystallization inhibition and cell cryopreservation.

Cyclodextrin-based cryoprotectants were developed. α-TMCD, which can be easily put into large-scale production, showed enhanced cell viabilities of 19.97 ± 0.78%, 13.93 ± 4.46% and 19.10 ± 0.95% against GES-1, hucMSCs and A549 cells. Moreover, the viable cells observed by light microscope imaging showed that the enhanced hucMSC cell number percentage of α-TMCD was 103.2%. An α-TMCD-DMSO-based CPA exhibited an enhanced cryoprotective effect by a mechanism of DMSO-enhanced cell penetrating effect and α-TMCD-DMSO synergistically enhanced IMA ability. α-TMCD exhibited potential for the discovery of macrocycle-molecule-based cryoprotectants.

Design and synthesis of novel benzimidazole-iminosugars linked a substituted phenyl group and their inhibitory activities against ß-glucosidase.

A series of novel benzimidazole-iminosugars linked a (substuituted) phenyl group on benzene ring of benzimidazole 5(a-p) and 6(a-p) have been rationally designed and conveniently synthesized through Suzuki coupling reaction in high yields. All compounds have been evaluated for their inhibitory activities against ß-glucosidase (almond). Six compounds 5d, 6d, 6e, 6i, 6n, and 6p showed more significant inhibitory activities with IC50 values in the range of 0.03-0.08 µM, almost 10-fold improved than that of the parent analogue 4, and much higher than that of the positive control castanospermine. The additional phenyl ring and the electron donating groups on it would be beneficial for the activity. Compounds 6d, 6n, and 4 had been chosen to be tested for their inhibition types against ß-glucosidase. Interestingly, three compounds have different inhibition types although they had very similar structure. Their Ki values were calculated to be 0.02 ± 0.01 µM, 0.02 ± 0.01 µM, and 0.66 ± 0.14 µM, respectively. The equilibrium dissociation constant (KD) for 6d, 6n, and 4 and ß-glucosidase was 0.04 µM, 0.03 µM and 0.45 µM by the ITC-based assay, respectively. Molecular docking work suggests that such benzimidazole-iminosugars derivatives might bind to the active site of ß-glucosidase mainly through hydrogen bonds, the additional phenyl ring towards the solvent-exposed region played an important effect on their inhibitory activity against ß-glucosidase.

Synthesis, Renal Clearance, and Photothermal Therapy Based on the Self-Assembly of a Nanomedicine Consisting of Quaterrylene Bisimide and Glycocluster Conjugates.

Renal-clearable nanomedicines are considered the next generation of nanomedicines, and show potential application for future clinical translations. However, it is important to determine whether self-assembly can form large aggregates that accrue in tumors and then tailor the size of these assemblies to be excreted renally. In this paper, a renal-clearable nanomedicine based on quanterrylene bisimide-mannose conjugates (QDI-Man) was developed. QDI-Man showed a high renal clearance efficiency of 80.31 ± 2.85% in mice. We confirmed that the self-assembly of QDI-Man exhibited a dynamic adjustment process through the renal filtration thresholds, that is, "aggregation → self-regulating the aggregate size through the renal filtration thresholds → reaggregating into aggregates". Benefiting from the modification of mannose-based glycoclusters, QDI-Man showed selective photothermal therapy because of the mannose receptors overexpressed in breast cancer cells, and showed good photothermal therapy in mice. This paper developed a dynamic adjustment theory for effective renal clearance based on organic self-assembly.
