Geraniin, a polyphenol derived from the fruit peel of Nephelium lappaceum L., has been shown to possess anti-inflammatory and antioxidant properties in the cardiovascular system. The present study explored whether geraniin could protect against an isoproterenol (ISO)-induced cardiac hypertrophy model. Mice in the ISO group received an intraperitoneal injection of ISO (5 mg/kg) once daily for 9 days, and the administration group were injected with ISO after 5 days of treatment with geraniin or spironolactone. Potential therapeutic effects and related mechanisms analysed by anatomical coefficients, histopathology, blood biochemical indices, reverse transcription-PCR and immunoblotting. Geraniin decreased the cardiac pathologic remodeling and myocardial fibrosis induced by ISO, as evidenced by the modifications to anatomical coefficients, as well as the reduction in collagen I/III á1mRNA and protein expression and cross-sectional area in hypertrophic cardiac tissue. In addition, geraniin treatment reduced ISO-induced increase in the mRNA and protein expression levels of interleukin (IL)-6, IL-1β and tumor necrosis factor-α, whereas ISO-induced IL-10 showed the opposite behaviour in hypertrophic cardiac tissue.Further analysis showed that geraniin partially reversed the ISO-induced increase in malondialdehyde and nitric oxide, and the ISO-induced decrease in glutathione, superoxide dismutase and glutathione. Furthermore, it suppressed the ISO-induced cellular apoptosis of hypertrophic cardiac tissue, as evidenced by the decrease in Bcell lymphoma-2 (Bcl-2)-associated X/caspase-3/caspase-9 expression, increase in Bcl-2 expression, and decrease in TdT-mediated dUTP nick-end labeling-positive cells.These findings suggest that geraniin can attenuate ISO-induced cardiac hypertrophy by inhibiting inflammation, oxidative stress and cellular apoptosis.

Objective:To explore the correlation between abnormal expression of serum 25(OH)D and immune-related fac-tors and subclinical atherosclerosis(AS)in patients with impaired glucose regulation.Methods:A total of 142 patients with im-paired glucose regulation admitted to Zaozhuang Municipal Hospital from December 2019 to April 2021 were selected.The patients with impaired glucose regulation were selected as the control group(n=86)and patients with subclinical atherosclerosis were selected as the observation group(n=56)according to carotid ultrasound examination and bramolecular pulse wave conduction velocity.The serum 25(OH)D and immune factors were compared between the two groups.Carotid ultrasound was used to measure the carotid inti-media thickness,and Pearson method was used to determine the correlation between the intimedia thickness,25(OH)D and immune factors.Baseline data and hematological indicators were collected,univariate and multivariate Logistic regression analysis was per-formed to determine the influencing factors of subclinical atherosclerosis,and ROC curve was used to evaluate the diagnostic efficacy of serum 25(OH)D and immune factors in subclinical atherosclerosis.Results:The serum 25(OH)D[(24.01±4.87)mmol/L vs(30.74±5.01)mmol/L,t=7.909,P=0.000)in the observation group was significantly lower than that of control group.TNF-α[(48.32±8.02)ng/L vs(33.21±9.00)ng/L,t=10.199,P=0.000)and IL-6[(41.22±9.43)ng/L vs(30.21±7.01)ng/L,t=7.492,P=0.000)in ob-servation group were significantly higher than those in control group.Carotid intima-media thickness was negatively correlated with se-rum 25(OH)D(r=-0.428,P<0.001),and was positively correlated with serum TNF-α and IL-6(r=0.574,0.577,P<0.001).Logis-tic regression analysis showed that serum 25(OH)D(OR=0.520,95%CI:0.401～0.675),serum TNF-α(OR=1.667,95%CI:1.131～2.457)and serum IL-6(OR=1.478,95%CI:1.213～1.802)were the influencing factors of subclinical atherosclerosis.ROC curve showed that the optimal cut-off value of serum 25(OH)D was 28.32 mmol/L,and the corresponding sensitivity,specificity and AUC were 69.64%,70.93%and 0.803(95%CI:0.749～0.855),respectively.The critical value of serum TNF-α was 40.56 ng/L,corre-sponding sensitivity was 71.43%,specificity was 72.09%,and AUC was 0.761(95%CI:0.717～0.823).Serum IL-6 cut-off value was 36.13 ng/L,corresponding sensitivity was 60.71%,specificity was 60.47%,and AUC was 0.627(95%CI:0.566～0.702).The sensitivity,specificity and AUC of regression analysis were 85.71%,81.40%and 0.889(95%CI:0.830～0.915).Conclusion:Serum 25(OH)D and immune-related factors alone and in combination can effectively predict the occurrence of subclinical atherosclerosis,which is correlated with carotid intima-media thickness,and serum 25(OH)D and immune-related factors are predictors of subclinical atherosclerosis.

BACKGROUND:Numerous scholars have previously researched certain greater tuberosity fractures and the procedures used to treat them.Few researchers,however,have studied the comminuted split fracture of the greater tuberosity of the humerus(Liu-Gang type IV)with rotator cuff tear in great detail. OBJECTIVE:To compare the clinical therapeutic effect of open repair position modified calcaneal plate combined with suture anchors and proximal humeral internal locking system(PHILOS)plate in the treatment of comminuted fracture of split-type greater tuberosity of humerus combined with rotator cuff tears(Liu-Gang type IV). METHODS:Case data of 30 patients with comminuted fracture of split-type greater tuberosity of humerus combined with rotator cuff tears(Liu-Gang type IV)from May 2012 to May 2022 were retrospectively analyzed.They were divided into the modified calcaneal plate combined with suture anchor group(group A)and the PHILOS with#2 Johnson group(group B),with 15 cases in each group.Intraoperative blood loss,surgical time,and incision length of all patients were recorded.Pain visual analog scale score,Constant-Murley score,as well as shoulder joint abduction,forward flexion,external rotation,and dorsal expansion activities during the last follow-up(>1 year)were evaluated. RESULTS AND CONCLUSION:(1)The surgical incision length and operation time were shorter,and blood loss was less in group A than those in group B(P<0.05).(2)No significant difference in visual analog scale score and Constant-Murley score was detected between the two groups(P>0.05).(3)During the last follow-up,forward flexion in group A was better than that in group B(P<0.05).No significant difference in abduction,external rotation,and dorsal expansion was determined between group A and group B(P>0.05).(4)In terms of complications,there was 1 case of shoulder joint pain and discomfort in group A(7%),2 cases of subacromial impingement syndrome,2 cases of upward movement of nodules,and 2 cases of shoulder joint pain(40%)in group B.There were significant differences in complication rates between the two groups(P=0.031).(5)In summary,the modified calcaneal plate combined with suture anchors in the treatment of comminuted fracture of split-type greater tuberosity of humerus combined with rotator cuff tears(Liu-Gang type IV)could better restore the forward flexion function of the shoulder joint and has a small incision,less blood loss,shorter operation time and fewer complications.

IKBKG is the essential modulator for nuclear factor-κB(NF-κB) signaling pathway, and mutations within this gene can lead to anhidrotic ectodermal dysplasia and immunodeficiency (EDA-ID). Here we report a male patient, who presented with mild frontal bossing, sparse hair, skin pigmentation, conical teeth, and recurrent infections involving bacteria, fungi, and viruses after one month of age, together with hypogammaglobulinemia. These symptoms were consistent with the phenotype of EDA-ID. Genetic analysis revealed a hemizygous mutation c.1249T > G (p.Cys417Gly) in exon 10 of the IKBKG gene in the patient. The mother of the patient was identified as heterozygous carriers of the same mutation. Immunological assessment revealed a significant reduction in memory B cells. The patient showed no skewed TCR diversity. PHA-induced T-cell proliferation was impaired. IFN-γ secretion by Th cells was significantly reduced after PHA stimulation. IκBα degradation rate retained the same in the patient. We summarized the clinical features of the patient and conducted immunological analysis, in order to increase pediatricians′awareness of this rare disease. For boys with early-onset recurrent infections together with ectodermal dysplasia, IKBKG mutation should be considered. In addition, genetic analysis is needed to exclude pseudogene interference and functional evaluations are required.

Using methylated pyrroloxicam as a starting material and following the principles of drug design such as bioisosterism and active site binding,we designed and synthesized ten structurally novel target compounds,whose structures were characterized by 1H NMR and MS analysis.The in vitro antitumor activity of these title compounds was evaluated by measuring their inhibitory activity against pancreatic cancer cells Capan-1,leukemia cells L1210,and human liver cancer cells SMMC-7721.The results showed that compound 6f(IC50=4.8±0.5 μmol/L)exhibited good inhibitory activity against Capan-1 pancreatic cancer cells,that compound 6b(IC50=2.6±0.3 μmol/L)showed good inhibitory activity against L1210 leukemia cells,and that compound 6c(IC50=2.1±0.2 μmol/L)displayed good inhibitory activity against SMMC-7721 human liver cancer cells.These preliminary results from the antitumor activity experiments suggest that the introduction of benzothiazine derivatives plays a certain role in enhancing the antitumor activity of this class of compounds.
