The effect of porcine SIRT5 on replication of foot and mouth disease virus type O(FMDV-O)and the underlying regulatory mechanism were investigated.Western blot and RT-qPCR analyses were employed to monitor expression of endoge-nous SIRT5 in PK-15 cells infected with FMDV-O.Three pairs of SIRT5-specific siRNAs were synthesized.Changes to SIRT5 and FMDV-O protein and transcript levels,in addition to virus copy numbers,were measured by western blot and RT-qPCR analyses.PK-15 cells were transfected with a eukaryotic SIRT5 expression plasmid.Western blot and RT-qPCR analyses were used to explore the impact of SIRT5 overexpression on FMDV-O replication.Meanwhile,RT-qPCR analysis was used to detect the effect of SIRT5 overexpression on the mRNA expression levels of type I interferon-stimulated genes induced by SeV and FMDV-O.The results showed that expression of SIRT5 was up-regulated in PK-15 cells infected with FMDV-O and siRNA interfered with SIRT5 to inhibit FMDV-O replication.SIRT5 overexpression promoted FMDV-O replication.SIRT5 over-expression decreased mRNA expression levels of interferon-stimulated genes induced by SeV and FMDV-O.These results suggest that FMDV-O infection stimulated expression of SIRT5 in PK-15 cells,while SIRT5 promoted FMDV-O rep-lication by inhibiting production of type I interferon-stimula-ted genes.These findings provide a reference to further ex-plore the mechanism underlying the ability of porcine SIRT5 to promote FMDV-O replication.

This review introduced the research progress of covalent modification strategies in local anesthetic drug delivery systems. As a commonly used and multimodal analgesic drug, local anesthetics have limited duration of action and potential toxicity in clinical application. In order to prolong the analgesic effect and reduce systemic toxicity, researchers are committed to the development of sustained-release local anesthetics with long-lasting dose-controlled-release functions. When it comes to the delivery of local anesthetics, the covalent modification strategy is a key approach. By covalently binding drugs to large molecule carriers, covalent modification strategies can improve drug stability, targeting and delivery efficiency. Macromolecular prodrugs can modulate the kinetic process of the drug, so that the drug is released in the form of the active ingredient and achieve better therapeutic effects. In recent years, stimulus-responsive macromolecular prodrugs have become a research hotpot for local anesthetic drug delivery systems, and the stimulus-responsive performance of macromolecular prodrugs can rapidly release drugs under internal and external stimulus conditions, and maintain low toxicity and high efficiency in blood circulation and normal tissues. These emerging research directions provide important guidance for prolonging the analgesic effect of local anesthetics and reducing systemic toxicity, and provide new idea for the development of more effective drug delivery systems in the future.

Objective To investigate the impact of microvascular obstruction (MVO) on the global and regional myocardial function by cardiac magnetic resonance feature-tracking (CMR-FT) in ST-segment-elevation myocardial infarction (STEMI) patients after percutaneous coronary intervention.Methods Consecutive acute STEMI patients who underwent cardiac magnetic resonance imaging 1 - 7 days after successful reperfusion by percutaneous coronary intervention treatment were included in this retrospective study. Based on the presence or absence of MVO on late gadolinium enhancement images, patients were divided into groups with MVO and without MVO. The infarct zone, adjacent zone, and remote zone were determined based on a myocardial 16-segment model. The radial strain (RS), circumferential strain (CS), and longitudinal strain (LS) of the global left ventricle (LV) and the infarct, adjacent, and remote zones were measured by CMR-FT from cine images and compared between patients with and without MVO using independent-samples t-test. Logistic regression analysis was used to assess the association of MVO with the impaired LV function.Results A total of 157 STEMI patients (mean age 56.66 ± 11.38 years) were enrolled. MVO was detected in 37.58% (59/157) of STEMI patients, and the mean size of MVO was 3.00 ±3.76 mL. Compared with patients without MVO (n =98 ), the MVO group had significantly reduced LV global RS (t= -4.30, P < 0.001), global CS (t= 4.99, P < 0.001), and global LS ( t= 3.51, P = 0.001). The RS and CS of the infarct zone in patients with MVO were significantly reduced (t= -3.38, P = 0.001; t= 2.64, P = 0.01; respectively) and the infarct size was significantly larger (t= 8.37, P < 0.001) than that of patients without MVO. The presence of LV MVO [OR= 4.10, 95%CI: 2.05 - 8.19, P<0.001) and its size [OR=1.38, 95%CI: 1.10-1.72, P=0.01], along with the heart rate and LV infarct size were significantly associated with impaired LV global CS in univariable Logistic regression analysis, while only heart rate (OR=1.08, 95%CI: 1.03 - 1.13, P=0.001) and LV infarct size (OR=1.10, 95%CI: 1.03 - 1.16, P=0.003) were independent influencing factors for the impaired LV global CS in multivariable Logistic regression analysis.Conclusion The infarct size was larger in STEMI patients with MVO, and MVO deteriorates the global and regional LV myocardial function.

Glioblastoma(GBM)is a lethal cancer with limited therapeutic options.Dendritic cell(DC)-based cancer vaccines provide a promising approach for GBM treatment.Clinical studies suggest that other immu-notherapeutic agents may be combined with DC vaccines to further enhance antitumor activity.Here,we report a GBM case with combination immunotherapy consisting of DC vaccines,anti-programmed death-1(anti-PD-1)and poly I:C as well as the chemotherapeutic agent cyclophosphamide that was integrated with standard chemoradiation therapy,and the patient remained disease-free for 69 months.The patient received DC vaccines loaded with multiple forms of tumor antigens,including mRNA-tumor associated antigens(TAA),mRNA-neoantigens,and hypochlorous acid(HOCl)-oxidized tumor lysates.Furthermore,mRNA-TAAAs were modified with a novel TriVac technology that fuses TAAs with a destabilization domain and inserts TAAs into full-length lysosomal associated membrane protein-1 to enhance major histo-compatibility complex(MHC)class Ⅰ and Ⅱ antigen presentation.The treatment consisted of 42 DC cancer vaccine infusions,26 anti-PD-1 antibody nivolumab administrations and 126 poly I:C injections for DC infusions.The patient also received 28 doses of cyclophosphamide for depletion of regulatory T cells.No immunotherapy-related adverse events were observed during the treatment.Robust antitumor CD4+and CD8+T-cell responses were detected.The patient remains free of disease progression.This is the first case report on the combination of the above three agents to treat glioblastoma patients.Our results suggest that integrated combination immunotherapy is safe and feasible for long-term treatment in this patient.A large-scale trial to validate these findings is warranted.

Objective:To investigate the clinical characteristics, diagnosis and treatment of dermatomyositis with kidney neoplasm.Methods:The data of two patients with dermatomyositis complicated with kidney neoplasm in Tongji Hospital from January to February 2022 were retrospectively analyzed. The first case was a 55-year-old female, who was admitted with the chief complaints of recurrent erythema of upper extremities for 2 months and facial erythema for 1 month. Physical examination: erythema can be seen on upper limbs and face, no tenderness or percussion pain in kidney area. Myositis enzyme profile test showed that anti-Mi-2 antibody and anti-SSA /Ro-52 antibody were positive. Contrast CT showed nodular uneven enhancement in the right kidney with a size of 50 mm×41 mm. The second case was a 58-year-old female, who was admitted with the chief complaints of kidney occupying for a month. Physical examination: flaky erythema on face, no tenderness or percussion pain in kidney area. Myositis enzyme profile test showed that anti-Ro-52 antibody and anti-MDA5 antibody were positive. Contrast CT showed a significantly uneven enhanced mass with a size of about 50 mm×41 mm on left kidney. Both patients were diagnosed with kidney neoplasm before surgery and underwent laparoscopic partial nephrectomy in Tongji Hospital.Results:Both patients received regular oral prednisone after surgery. The pathological presentation of case 1 was papillary renal cell carcinoma, the facial erythema subsided 1 month after surgery, and there was no tumor recurrence for 13 months. The pathological presentation of case 2 was clear cell renal cell carcinoma, facial erythema subsided 2 weeks after surgery, and there was no tumor recurrence for 12 months.Conclusions:The diagnosis of dermatomyositis should be combined with clinical manifestations and laboratory examination, and the possibility of malignant tumor should be excluded due to the high likelihood of concomitant malignancy. For patients with dermatomyositis with kidney neoplasm, the main treatment is still surgery, and supplemented with glucocorticoid therapy.

Objective:To investigate the relationship between advanced glycation end products (AGEs) in the lens and type 2 diabetes mellitus.Methods:226 subjects were recruited between August 14 to September 14, 2018 from the Endocrinology Department of Central South University Xiangya Hospital, the Third Hospital of Changsha City, and the Fourth Hospital of Changsha City. The OGTT test, combined with clinical indicators, were used as the gold standard. Subjects were screened for type 2 diabetes using both the lens AGE fluorescence assay and the gold standard. Drawing the receiver operating characteristic (ROC) curve, we calculated the area under the curve (AUC) and its 95% CI and calculated the AGE for the diagnosis of type 2 diabetes. Sensitivity, specificity, Youden index, Kappa value, and its 95% CI, and the optimal cut-off value were determined according to the Youden index. Taking diabetes as the outcome indicator and AGE as the binary indicator, three logistic regression models were constructed. Stratified by age and sub-center, the differences between fasting blood glucose and 2 h postprandial blood glucose were compared between the AGE-negative and AGE-positive groups to determine the relationship between AGE and diabetes. Results:The area under the ROC curve was 0.86(95% CI: 0.81-0.91). According to the Youden index, the optimal cut-off point for AGE was 0.24. At this time, the sensitivity was 82.86(95% CI: 77.81-87.91), the specificity was 77.06(95% CI: 71.43-82.7), the Youden index was 59.92(95% CI: 53.36-66.49), the Kappa value was 79.62(95% CI: 74.22-85.02). Except for the 20-39-year-old group, the fasting blood glucose and 2 h postprandial blood glucose of the AGE-positive group in different age groups, different sub-centers, and the general population were higher than those of the AGE-negative group (all P<0.05). After adjusting for the confounding effects of age, gender, and sub-center (model 3), the relative risk of diabetes in the AGE-positive group was 11.75 times higher than the AGE-negative group (95% CI: 5.61-24.60), all with P<0.001. Conclusion:There was a high correlation between AGE in the lens and the risk of type 2 diabetes. When the cut-off point of AGE is 0.24, it had high sensitivity and specificity and could be used as a practical tool for early screening of type 2 diabetes.

ObjectiveTo explore the effect of Xianlian Jiedu prescription (XLJDP) on the proliferation and glycolysis of human colorectal cancer HCT-116 cells and the underlying mechanism. MethodHCT-116 cells were cultured with XLJDP and then the survival rate was examined by methyl thiazolyl tetrazolium (MTT) assay. The effect on the HCT116 cell proliferation was detected by colony formation assay and 5-ethynyl-2′-deoxyuridine (EDU) incorporation assay. The amount of glucose consumed by HCT-116 cells was measured by glucose test kit, and the amount of produced lactic acid was determined by lactic acid test kit 48 h after the treatment with XLJDP. The expression of glycolysis-related proteins mammalian target of rapamycin (mTOR), phosphorylated mTOR (p-mTOR), glucose transporter 1 (GLUT1), and lactate dehydrogenase (LDHA) was detected by Western blot. ResultThe half-maximal inhibitory concentration (IC50) of XLJDP against HCT-116 cells was 6.82 g·L-1. Compared with the blank group, XLJDP (1.625, 3.25, 6.50 g·L-1) inhibited the proliferation of HCT-116 cells (P<0.05, P<0.01). Moreover, compared with the blank group, XLJDP (1.625, 3.25, 6.50 g·L-1) suppressed glucose uptake and lactic acid production in a dose-dependent manner (P<0.05, P<0.01). The expression of p-mTOR/mTOR, LDHA, and GLUT1 was down-regulated by XLJDP (P<0.05, P<0.01). ConclusionXLJDP can significantly inhibit the proliferation and the Warburg effect of glycolysis in colorectal cancer cells by regulating the mTOR signaling pathway and the down-regulating the expression of LDHA, GLUT1, and other key proteins and enzymes in glycolysis.

OBJECTIVE:
To explore effects of acupotomy on pain, function, gait and serum inflammatory factors in patients with knee osteoarthritis(KOA).
METHODS:
From December 2017 to June 2019, 110 patients with KOA were collected and divided into acupotomy group(56 cases) and western medicine group(54 cases) by using random number table method. In acupotomy group, there were 16 males and 40 females, aged from 46 to 74 years old with an average of (62.98±6.68) years old, the course of disease ranged from 1 to 240 months with an average of 24.5(15.25, 33.00) months;were treated with acupotomy on the pain points around knee joint once a week for 3 weeks. In western medicine group, there were 18 males and 36 females, aged from 47 to 73 years old with an average of (64.19±5.98 ) years old;the course of disease ranged from 1 to 220 months with an average of 25.00(13.75, 33.00) months;were took celecoxib capsule orally, 200 mg once a day for 3 weeks. Oxford Knee Score(OKS) was performed before treatment, 3 weeks and 3 months after treatment. Gait kinematics analysis and serum levels of tumor necrosis factor-α(TNF-α) and interleukin-1β (IL-1β) were measured before and after treatment for 3 weeks.
RESULTS:
All patients were followed up from 6 to 24 months with an average of(15.03±4.55) months. OKS between two groups decreased significantly at 3 weeks and 3 months after treatment(P<0.001). Functional scores and overall scores in acupotomology group were significantly decreased at 3 months compared with 3 weeks after treatment(P<0.001). OKS of acupotomy group were significantly lower than those of western medicine group at 3 weeks and 3 months after treatment(P<0.05). Gait speed, frequency and length between two groups were significantly improved at 3 weeks after treatment(P<0.05). At 3 weeks after treatment, gait freguency of acupotomy group was significantly improved compared with western medicine group(P<0.05). TNF-α and IL-1β were significantly lower in both groups at 3 weeks after treatment than before treatment(P<0.05). At 3 weeks after treatment, level of IL-1 β was lower in western medicine group than in acupotomy group(P<0.05), and difference in TNF-α level was not statistically significant(P>0.05).
CONCLUSION
Acupotomology of pain points could significantly improve pain, function, gait, and decreased serum inflammatory factors at early to mid stage of KOA patients, in particular, it is superior to non-steroidal anti-inflammatory drugs in terms of knee function recovery and cadence improvement.
