Objective: To investigate the effect of rigosertib (RGS) combined with classic chemotherapy drugs including 5-fluorouracil, oxaliplatin, and irinotecan in colorectal cancer. Methods: Explore the synergy effects of RGS and 5-fluorouracil (5-FU), oxaliplatin (OXA), and irinotecan (IRI) on colorectal cancer by subcutaneously transplanted tumor models of mice. The mice were randomly divided into control group, RGS group, 5-FU group, OXA group, IRI group, 5-FU+ RGS group, OXA+ RGS group and IRI+ RGS group. The synergy effects of RGS and OXA on KRAS mutant colorectal cancer cell lines in vitro was detected by CCK-8. Ki-67 immunohistochemistry and TdT-mediated dUTP nick-end labeling (TUNEL) staining were performed on the mouse tumor tissue sections, and the extracted tumor tissue was analyzed by western blot. The blood samples of mice after chemotherapy and RGS treatment were collected, blood routine and liver and kidney function analysis were conducted, and H&E staining on liver sections was performed to observe the side effects of chemotherapy and RGS. Results: The subcutaneously transplanted tumor models were established successfully in all groups. 55 days after administration, the fold change of tumor size of OXA+ RGS group was 37.019±8.634, which is significantly smaller than 77.571±15.387 of RGS group (P=0.029) and 92.500±13.279 of OXA group (P=0.008). Immunohistochemical staining showed that the Ki-67 index of tumor tissue in control group, OXA group, RGS group and OXA+ RGS group were (100.0±16.8)%, (35.6±11.3)%, (54.5±18.1)% and (15.4±3.9)%, respectively. The Ki-67 index of OXA+ RGS group was significantly lower than that in control group (P=0.014), but there was no significant difference compared to OXA group and RGS group (OXA: P=0.549; RGS: P=0.218). TUNEL fluorescence staining showed that the apoptotic level of OXA+ RGS group was 3.878±0.547, which was significantly higher than 1.515±0.442 of OXA group (P=0.005) and 1.966±0.261 of RGS group (P=0.008). Western blot showed that the expressions of apoptosis related proteins such as cleaved-PARP, cleaved-caspase 3 and cleaved-caspase 8 in the tumor tissues of mice in the OXA+ RGS group were higher than those in control group, OXA group and RGS group. After the mice received RGS combined with chemotherapy drugs, there was no significant effect on liver and kidney function indexes, but the combined use of oxaliplatin and RGS significantly reduced the white blood cells [(0.385±0.215)×10(9)/L vs (5.598±0.605)×10(9)/L, P<0.001] and hemoglobin[(56.000±24.000)g/L vs (153.333±2.231)g/L, P=0.001] of the mice. RGS, chemotherapy combined with RGS and chemotherapy alone did not significantly increase the damage to liver cells. Conclusions: The combination of RGS and oxaliplatin has a stronger anti-tumor effect on KRAS mutant colorectal cancer. RGS single agent will not cause significant bone marrow suppression and hepatorenal injury in mice, but its side effects may increase correspondingly after combined with chemotherapy.

Mibefradil improves skeletal muscle mass, function and structure in obese mice / 南方医科大学学报

OBJECTIVE@#To observe the effect of mibefradil on skeletal muscle mass, function and structure in obese mice.@*METHODS@#Fifteen 6-week-old C57BL/6 mice were randomized equally into normal diet group (control group), high-fat diet (HFD) group and high-fat diet +mibefradil intervention group (HFD +Mibe group). The grip strength of the mice was measured using an electronic grip strength meter, and the muscle content of the hindlimb was analyzed by X-ray absorptiometry (DXA). Triglyceride (TG) and total cholesterol (TC) levels of the mice were measured with GPO-PAP method. The cross-sectional area of the muscle fibers was observed with HE staining. The changes in the level of autophagy in the muscles were detected by Western blotting and immunofluorescence assay, and the activation of the Akt/mTOR signaling pathway was detected with Western blotting.@*RESULTS@#Compared with those in the control group, the mice in HFD group had a significantly greater body weight, lower relative grip strength, smaller average cross sectional area of the muscle fibers, and a lower hindlimb muscle ratio (P < 0.05). Immunofluorescence assay revealed a homogenous distribution of LC3 emitting light red fluorescence in the cytoplasm in the muscle cells in HFD group and HFD+Mibe group, while bright spots of red fluorescence were detected in HFD group. In HFD group, the muscular tissues of the mice showed an increased expression level of LC3 II protein with lowered expressions of p62 protein and phosphorylated AKT and mTOR (P < 0.05). Mibefradil treatment significantly reduced body weight of the mice, lowered the expression level of p62 protein, and increased forelimb grip strength, hindlimb muscle ratio, cross-sectional area of the muscle fibers, and the expression levels of LC3 II protein and phosphorylated AKT and mTOR (P < 0.05).@*CONCLUSION@#Mibefradil treatment can moderate high-fat diet-induced weight gain and improve muscle mass and function in obese mice possibly by activating AKT/mTOR signal pathway to improve lipid metabolism and inhibit obesityinduced autophagy.

ConclusionWe employed the traditional Chinese medicine（TCM） inheritance auxiliary platform to explore the compatibility of Citri Sarcodactylis Fructus-containing clinical prescriptions and the corresponding TCM syndromes， which intuitively showcased the medication rules of Citri Sarcodactylis Fructus. Specifically， Citri Sarcodactylis Fructus was mainly combined with the medicines for tonifying Qi， invigorating Qi， tonifying blood， alleviating edema and promoting urination， promoting digestion， and activating blood and relieving pain to treat different TCM syndromes. While soothing liver， regulating Qi， harmonizing stomach， and relieving pain， the combinations tonify and activate blood， invigorate spleen， and resolve dampness. The findings are of great significance to the rational application of Citri Sarcodactylis Fructus， the development of health food， and the research of new drugs and will bolster the development of Chinese medicine industry.

Changes in sensitivity of bilateral medial vestibular nuclear neurons responding to input stimuli during vestibular compensation and the underlying ionic mechanism / 生理学报

Vestibular compensation is an important model for developing the prevention and intervention strategies of vestibular disorders, and investigating the plasticity of the adult central nervous system induced by peripheral injury. Medial vestibular nucleus (MVN) in brainstem is critical center for vestibular compensation. Its neuronal excitability and sensitivity have been implicated in normal function of vestibular system. Previous studies mainly focused on the changes in neuronal excitability of the MVN in lesional side of the rat model of vestibular compensation following the unilateral labyrinthectomy (UL). However, the plasticity of sensitivity of bilateral MVN neurons dynamically responding to input stimuli is still largely unknown. In the present study, by using qPCR, whole-cell patch clamp recording in acute brain slices and behavioral techniques, we observed that 6 h after UL, rats showed a significant deficit in spontaneous locomotion, and a decrease in excitability of type B neurons in the ipsilesional rather than contralesional MVN. By contrast, type B neurons in the contralesional rather than ipsilesional MVN exhibited an increase in response sensitivity to the ramp and step input current stimuli. One week after UL, both the neuronal excitability of the ipsilesional MVN and the neuronal sensitivity of the contralesional MVN recovered to the baseline, accompanied by a compensation of spontaneous locomotion. In addition, the data showed that the small conductance Ca2+-activated K+ (SK) channel involved in the regulation of type B MVN neuronal sensitivity, showed a selective decrease in expression in the contralesional MVN 6 h after UL, and returned to normal level 1 week later. Pharmacological blockage of SK channel in contralateral MVN to inhibit the UL-induced functional plasticity of SK channel significantly delayed the compensation of vestibular motor dysfunction. These results suggest that the changes in plasticity of the ipsilesional MVN neuronal excitability, together with changes in the contralesional MVN neuronal sensitivity, may both contribute to the development of vestibular symptoms as well as vestibular compensation, and SK channel may be an essential ionic mechanism responsible for the dynamic changes of MVN neuronal sensitivity during vestibular compensation.

The relationship between comorbidity and oral health in hospitalized elderly patients / 中华老年医学杂志

Objective:To explore the relationship between comorbidity and oral health in the elderly.Methods:As a retrospective study, 852 patients hospitalized at the Department of Geriatrics, the First Affiliated Hospital of Chongqing Medical University between July 2017 and July 2018 were selected, including 380 male and 472 female patients, with 274 between 60 and 74 years old, 519 between 75 and 89 years old and 59 ≥90 years old.Patients' clinical data and records on the Chinese version of the Kayser-Jones Brief Oral Health Status Examination(BOHSE)were retrospectively collected.The cumulative illness rating scale(CIRS)and the Chinese version of the BOHSE scale were calculated.The distribution of oral health problems measured using indicators in the Chinese version of the BOHSE scale was compared between the comorbidity group and the non-comorbidity group.The relationship between the CIRS score and oral health was analyzed by multiple linear regression.Results:Of the 808 patients with comorbidities, each patient had(3.63±1.33), (4.26±1.64)and(5.14±1.90)diseases, respectively, in the 60-74, 75-89 and ≥90 age groups( F=35.555, P<0.01). The age groups' CIRS scores were(8.88±3.59), (11.67±4.32)and(13.64±4.42)( F=51.532, P<0.01). The incidence of oral problems in hospitalized elderly patients was 92.72 %(790/852). The average oral health BOHSE score was(4.58 ± 2.88). There was a significant difference in oral health condition among the 60-74, 75-89 and ≥90 age groups( F=19.370, P<0.05). There were also significant differences in gums between teeth and/or under artificial teeth, condition of natural teeth and condition of artificial teeth between hospitalized elderly patients with and without comorbidities(all P<0.05). CIRS scores of patients with comorbidities were correlated with scores of natural tooth condition and pairs of teeth in the chewing position(natural or artificial)( t values were 2.565 and 2.495, P<0.05 for both). Conclusions:The comorbidity rate of hospitalized elderly patients is high and their oral health problems are common.As the age increases, the number of comorbidities increases and oral health condition becomes worse.The natural tooth condition and pairs of teeth in the chewing position(natural or artificial)are related to the severity of comorbidities in the elderly.

Objective:To investigate the relationship between hyperuricemia and outcome in patients with acute ischemic stroke.Methods:Patients with acute ischemic stroke admitted to Department of Neurology, Putuo Hospital, Shanghai University of Tranditional Chinese Medicine between January 2020 and September 2020 were enrolled retrospectively. The modified Rankin Scale (mRS) score was used to evaluate the clinical outcome 3 months after the onset. ≤2 was considered as good outcome, and >2 was considered as poor outcome. The demography and baseline characteristics were compared between the good outcome group and the poor outcome group. Multivariate logistic regression analysis was used to determine the independent influencing factors of the outcome. Results:A total of 210 patients were included, their age was 69.87±62.62 years. There were 125 males (59.52%) and 85 females (40.48%). The baseline median National Institutes of Health Stroke Scale (NIHSS) score was 4. The serum uric acid level in 169 patients (80.48%) was normal and 41 (19.52%) had hyperuricemia; 120 patients (57.14%) had a good outcome, and 90 (42.86%) had a poor outcome. Blood glucose level, serum uric acid level, baseline NIHSS score and the proportions of diabetes mellitus, history of stroke or transient ischemic attack, hyperuricemia in the poor outcome group were significantly higher than those in the good outcome group (all P<0.05). Multivariate logistic regression analysis showed that diabetes mellitus (odds ratio [ OR] 2.735, 95% confidence interval [ CI] 1.461-5.121; P=0.002), hyperuricemia ( OR 2.400, 95% CI 1.102-5.228; P=0.027), and higher baseline NIHSS score ( OR 1.233, 95% CI 1.118-1.360; P<0.001) were the independent risk factors for poor outcome in patient with acute ischemic stroke. Conclusion:Hyperuricemia is an independent risk factor for poor outcome in patients with acute ischemic stroke.

Cyclic Stretch Induces Adhesion of VSMCs with Platelet-Derived Microparticles and the Role in Autophagy / 医用生物力学

Objective To investigate the effect of cyclic stretch on adhesion of vascular smooth muscle cells (VSMCs) with platelet-derived microparticles (PMPs), and the role of PMPs in VSMC autophagy. Methods Cyclic stretch with the magnitude of 5% (simulating physiological mechanical stretch) or 15% (simulating pathological mechanical stretch) was subjected to VSMCs in vitro by using FX-5000T cyclic stretch loading system, and the adhesion of PMPs in VSMCs was detected by using flow cytometry. Immunofluorescence was used to detect the expression of autophagy microtubule associated protein light chain 3 (LC3) after 24 h stimulation with PMPs. Western blotting was used to detect the expression of autophagy related protein (Atg) in VSMCs after 24 h stimulation by PMPs. Results Compared with 5% cyclic stretch, 15% cyclic stretch significantly increased the adhesion ability of VSMCs with PMPs. Immunofluorescence and Western blotting result revealed that PMPs stimulation significantly increased the expression of autophagy marker protein LC3 in VSMCs. Furthermore, the protein expressions of Atg5, Atg7 and Atg12 were all significantly increased in VSMCs stimulated with PMPs. Conclusions High cyclic stretch may enhance the autophagy of VSMCs by promoting the adhesion of PMPs, which will subsequently increase the expressions of Atg5, Atg7, Atg12 and LC3.

Effect of Shaolin internal qigong exercise on the surface electromyography signals of shoulder muscle groups in patients with capsulitis of the shoulder / 针灸推拿医学（英文版）

Objective: To unveil the efficacy of Shaolin internal qigong exercise in treating capsulitis of the shoulder (CS) and explore objective outcome measures by observing the changes in the surface electromyography (sEMG) signals of shoulder muscle groups after regular practice of Shaolin internal qigong exercise in CS patients. Methods: Sixty CS patients were randomized into two groups by the random number table method, with 30 cases in each group. Patients in the qigong group practiced Shaolin internal qigong exercise on a regular basis, while patients in the electroacupuncture (EA) group received EA treatment. Before and after treatment, the sEMG signals of six muscles, i.e. biceps brachii, triceps brachii, deltoid, pectoralis major, latissimus dorsi and trapezius muscles, of the affected side were recorded at 45° abduction of the shoulder, 60° forward flexion and 90° internal rotation with the elbow flexed during maximal isometric contraction, and the integrated electromyography (iEMG) of each muscle was calculated. Results: The total effective rate was 93.3％ in the qigong group, higher than 83.3％ in the EA group (P<0.05). Intra-group comparison showed that the iEMG of biceps brachii, triceps brachii, pectoralis major and deltoid muscles in the qigong group increased significantly after intervention at 45° abduction of the shoulder, 60° forward flexion and 90° internal rotation with the elbow flexed (all P<0.05), and the iEMG of trapezius and latissimus dorsi muscles decreased (both P<0.05); in the EA group, the iEMG of biceps brachii, pectoralis major and deltoid muscles increased significantly during contraction (all P<0.05), while the iEMG of triceps brachii, trapezius and latissimus dorsi muscles had no significant changes (all P>0.05). After intervention, there were significant differences in the iEMG of most of muscles between the two groups (all P<0.05), except for the iEMG of deltoid muscle at 45° of abduction of the shoulder joint during isometric contraction (P>0.05). Conclusion: Shaolin internal qigong exercise can effectively increase the motion intensity of the biceps brachii, triceps brachii, pectoralis major and deltoid muscles and reduce the compensation of the latissimus dorsi and trapezius muscles in CS patients; compared with EA, it produces a better result in improving the coordination and stability in shoulder joint movements.

Objective:To investigate the interfering factors in the determination of creatinine(Cr) using the American Clinical Laboratory Standards Association (CLSI) EP7-A3 document.Methods:According to the CLSI EP7-A3 document, fresh serum (no hemolysis, lipemia, and jaundice) was used on the day of the experiment and confirmed the interfering substances through the pairing difference experiment and the point-to-point analysis method was used in the dose effect experiment to clarify the difference of interfering substances.Results:Triglyceride (16.94 mmol/L), dobutamine hydrochloride (4.01 μmol/L), ascorbic acid (298 μmol/L) did not interfere with the determination of Cr. Free bilirubin (684 μmol/L), conjugated bilirubin (684 μmol/L), calcium hydroxybenzene sulfonate (144 μmol/L) and hemoglobin (10 g/L) were used as the maximum concentrations of interferences for the dose effect test, the results showed that the above interferences had negative interference on the determination of Cr.Conclusion:According to EP7-A3, it is valuable to evaluate the interference factors of creatinine determination.

Aberrant Resting-State Functional Connectivity in the Default Mode Network in Pediatric Bipolar Disorder Patients with and without Psychotic Symptoms / 神经科学通报·英文版

Mood disorders/psychosis have been associated with dysfunctions in the default mode network (DMN). However, the relative contributions of DMN regions to state and trait disturbances in pediatric bipolar disorder (PBD) remain unclear. The aim of this study was to investigate the possible mechanisms of PBD through brain imaging and explore the influence of psychotic symptoms on functional alterations in PBD patients. Twenty-nine psychotic and 26 non-psychotic PBD patients, as well as 19 age- and sex-matched healthy controls underwent a resting-state functional MRI scan and the data were analyzed by independent component analysis. The DMN component from the fMRI data was extracted for each participant. Spearman's rank correlation analysis was performed between aberrant connectivity and clinical measurements. The results demonstrated that psychotic PBD was characterized by aberrant DMN connectivity in the anterior cingulate cortex/medial prefrontal cortex, bilateral caudate nucleus, bilateral angular gyri, and left middle temporal gyrus, while non-psychotic PBD was not, suggesting further impairment with the development of psychosis. In summary, we demonstrated unique impairment in DMN functional connectivity in the psychotic PBD group. These specific neuroanatomical abnormalities may shed light on the underlying pathophysiology and presentation of PBD.
