Incremental value of epicardial fat volume on predicting obstructive coronary artery disease with myocardial ischemia / 中华心血管病杂志

Objective: This study aimed to investigate the association between epicardial fat volume (EFV) and obstructive coronary artery disease (CAD) with myocardial ischemia, and evaluate the incremental value of EFV on top of traditional risk factors and coronary artery calcium (CAC) in predicting obstructive CAD with myocardial ischemia. Methods: This study was a retrospective cross-sectional study. Patients with suspected CAD who underwent coronary angiography (CAG) and single photon emission computerized tomography-myocardial perfusion imaging (SPECT-MPI) at the Third Affiliated Hospital of Soochow University from March 2018 to November 2019 were consecutively enrolled. EFV and CAC were measured by non-contrast chest computed tomography (CT) scan. Obstructive CAD was defined as coronary artery stenosis≥50% in at least one of the major epicardial coronary arteries, and myocardial ischemia was defined as reversible perfusion defects in stress and rest MPI. Obstructive CAD with myocardial ischemia was defined in patients with coronary stenosis severity≥50% and reversible perfusion defects in the corresponding areas of SPECT-MPI. Patients with myocardial ischemia bot without obstructive CAD were defined as none-obstructive CAD with myocardial ischemia group. We collected and compared the general clinical data, CAC and EFV between the two groups. Multivariable logistic regression analysis was performed to identify the relationship between EFV and obstructive CAD with myocardial ischemia. ROC curves were performed to determine whether addition of EFV improved predictive value beyond traditional risk factors and CAC for obstructive CAD with myocardial ischemia. Results: Among the 164 patients with suspected CAD, 111 patients were males, and average age was (61.4±9.9) years old. 62 (37.8%) patients were included into the obstructive CAD with myocardial ischemia group. 102 (62.2%) patients were included into the none-obstructive CAD with myocardial ischemia group. EFV was significantly higher in obstructive CAD with myocardial ischemia group than in none-obstructive CAD with myocardial ischemia group ((135.63±33.29)cm3 and (105.18±31.16)cm3, P<0.01). Univariate regression analysis showed the risk of obstructive CAD with myocardial ischemia increased by 1.96 times for each SD increase in EFV(OR 2.96; 95%CI, 1.89-4.62; P<0.01). After adjustment for traditional risk factors and CAC, EFV remained as an independent predictor for obstructive CAD with myocardial ischemia (OR, 4.48, 95%CI, 2.17-9.23; P<0.01). Addition of EFV to CAC and traditional risk factors was related to larger AUC for predicting obstructive CAD with myocardial ischemia (0.90 vs. 0.85, P=0.04, 95%CI: 0.85-0.95) and the global chi-square increased by 21.81 (P<0.05). Conclusions: EFV is an independent predictor for obstructive CAD with myocardial ischemia. Addition of EFV to traditional risk factors and CAC has incremental value for predicting obstructive CAD with myocardial ischemia in this patient cohort.

Investigation of arterial stiffness and its influencing factors in prediabetic population / 中华超声影像学杂志

Objective:To explore the level of arterial stiffness and its influencing factors in prediabetic population.Methods:From June 2021 to June 2022, 207 prediabetes patients were prospectively and randomly recruited from the physical examination center and outpatient clinic of Tangdu Hospital of Air Force Military Medical University to be the prediabetic group and 130 healthy volunteers at the same time with the same gender and age as the healthy controls. The carotid-femoral pulse wave velocity (PWV), brachial-radial PWV, and femoral-ankle PWV were measured by an automatic ultrasonic arterial stiffness measurement technology. The common carotid artery wall intima-media thickness (IMT) and left heart function were routinely evaluated. A questionnaire was designed to investigate the subjects′ smoking, drinking, diet, staying up late, exercise and other living habits. Comparison between groups and multivariate linear regression analysis were used to analyze the relevant data.Results:The carotid-femoral PWV and common carotid artery wall IMT in prediabetic group were significantly higher than those in healthy controls [(7.10±2.00)m/s vs (6.26±1.14)m/s, (0.57±0.11)mm vs (0.51±0.08)mm; both P<0.001], but there were no significant differences in the brachial-radial PWV and femoral-ankle PWV between the two groups (both P>0.05). Multivariate linear regression analysis showed that prediabetes was an independent influencing factor in carotid-femoral PWV after adjusting for confounding factors ( P<0.001), in addition, age ( P<0.001), diastolic blood pressure ( P<0.001), staying up late ( P=0.011) and low density lipoprotein cholesterol ( P=0.022) were also the independent influencing factors of carotid-femoral PWV. Conclusions:Compared with healthy people, the stiffness of aorta is significantly increased in prediabetic people, but there is no significant change in the stiffness of peripheral arteries. Prediabetes, age, diastolic blood pressure, staying up late and low density lipoprotein cholesterol are independent influencing factors of carotid-femoral PWV.

OBJECTIVE To analyze the clinical characteristics of nephrotic syndrome induced by sunitinib， and to provide reference for clinical rational drug use. METHODS Retrieved from CNKI， VIP， Wanfang data， PubMed， Web of Science and Medline， case report about sunitinib-induced nephrotic syndrome were collected from the inception to Oct. 30th， 2022. Those case reports were analyzed statistically in terms of gender， age， primary disease， drug use， clinical manifestations， treatment and outcome. RESULTS A total of 15 pieces of literature were collected and 17 patients were involved， including 10 males and 7 females. The average age of patients was （59.35±15.72） years. Among 17 patients， there were 10 patients with renal cell carcinoma and 7 patients with gastrointestinal stromal tumor， all of whom received evidence-based medication； the dosage of sunitinib in 15 cases was recorded， and all of them were within the recommended range of the instructions； 9 patients received combined therapy； the time from sunitinib application to the occurrence of nephrotic syndrome was 21 days-52 months， of which 11 cases were ≤2 years. The clinical manifestations in 13 patients were described， including edema， oliguria， foamy urine， weight gain， fatigue， dyspnea on exertion， etc. Eight patients had other adverse reactions induced by sunitinib before suffering from nephrotic syndrome， including new hypertension or worsening of original hypertension， and hand-foot syndrome. Renal biopsy mainly manifested as thrombotic microangiopathy， focal segmental glomerular sclerosis and immune complex glomerulonephritis. Sunitinib withdrawal or dosage reduction was adopted in all patients， and they were given symptomatic treatment such as glucocorticoids and antihypertensive agents. Symptoms of 16 patients were improved， and renal function of one patient deteriorated and hemodialysis was started. Sunitinib was re-challenged in 6 patients， elevated creatinine and substantial proteinuria recurred in 5 patients. CONCLUSIONS In clinical use of sunitinib， it is advisable to periodically monitor renal function. In case of deterioration of renal function， albuminuria， edema， etc.， relevant examinations should be implemented in time， and symptomatic intervention should be taken as soon as possible. Besides， we should be alert to the recurrence of nephrotic syndrome after sunitinib rechallenge.

Screening of quantitative preparation quality markers of Zhibao Sanbian Wan / 药学学报

On the basis of the qualitative preparation quality markers of Zhibao Sanbian Wan (ZBSBW), we screened out the quantitative markers and evaluated the content consistency of ZBSBW. A method capable of simultaneously determining 34 compounds in ZBSBW was established based on HPLC-MS/MS, and 16 batches of ZBSBW were simultaneously analyzed by this method. Furthermore, we explored a general strategy for analyzing the component migration in preparation, plasma, brain tissue and cerebrospinal fluid. The methodological investigation was confirmed by linear range, recovery (85.10%-105.07%), precision (RSD: 1.37%-4.58%), stability, and repeatability (3.00%-12.45%), the established method was suitable for the detection and quantification of the compounds in ZBSBW. The contents of compounds in ZBSBW were all lower than 1 mg·g-1, and the contents and daily dose of nystose were the highest, followed by echinacoside, paeoniflorin, osthole and paeonol. The results of systematic clustering showed that the contents were consistent for ordinary preparations of ZBSBW. The principal component analysis showed that the components of berberine, ginsenoside Re, ginsenoside Rg1, pinoresinol diglucoside and tenuifolin had large variation, which contributed significantly to the grouping. The contents of echinacoside, verbascoside, polygalaxanthone Ⅲ, β-ecdysterone, osthole, alisol B 23-acetate, liquiritin and glycyrrhizic acid were stable from batch to batch. The animal experiment results showed that osthole, paeonol and liquiritin in ZBSBW could be absorbed into the blood and enter the brain tissue by passing through the blood-brain barrier. All animal studies were reviewed and approved by the Institutional Animal Care and Use Committee at Institute of Chinese Materia Medica, China Academy of Chinese Medical Sciences (No. 2020B071). The above compounds contributed the quantitative preparation quality markers of ZBSBW. In conclusion, the HPLC-MS/MS method established in this study was sensitive, accurate and rapid, and could be used for simultaneous quantification of 34 compounds and content consistency evaluation of multiple batches of preparations in ZBSBW. The result provided a methodological basis for the screening of quantitative preparation quality markers and material basis research of ZBSBW.

ObjectiveTo investigate the effects of the volatile oil of Linderae Radix on the apoptosis and autophagy of human gastric cancer cell line AGS， and to explore the regulatory role of adenosine monophosphate-activated protein kinase （AMPK）/mammalian target of rapamycin （mTOR） signaling pathway in this process. MethodThe volatile oil of Linderae Radix was extracted by steam distillation， and the effect of the volatile oil on the viability of AGS cells was detected by thiazolyl tetrazolium （MTT） colorimetry. The optimal intervention dose and time were determined according to the half maximal inhibitory concentration （IC50） for subsequent research. The blank， low， medium， and high-dose volatile oil （0， 15， 30， 60 mg·L-1） groups and the positive drug cyclophosphamide （CTX， 350 mg·L-1） group were designed. AGS cells were treated with different doses of volatile oil for 48 h. The changes in cell proliferation， cycle， and migration were measured by colony formation assay， flow cytometry， and cell scratch test， respectively. Hematoxylin-eosin （HE） staining was employed to observe the changes of cell morphology， Annexin-V/propidium iodide （PI） double staining to measure the apoptosis， and acridine orange （AO） staining to measure the autophagy level of the cells. Western blotting was employed to determine the expression of the autophagy effectors Beclin-1， p62， microtubule-associated protein 1-light chain 3 （LC3）， B-cell lymphoma-2 （Bcl-2）， Bcl-2-associated X protein （Bax）， cleaved Caspase-3， cleaved poly ADP-ribose polymerase （PARP）， adenosine monophosphate-activated protein kinase （AMPK）， phosphorylated AMPK （p-AMPK）， mTOR， and phosphorylated mTOR （p-mTOR）. ResultCompared with the blank group， 24 h and 48 h of intervention with the volatile oil of Linderae Radix inhibited the viability of AGS cells in a concentration- and time-dependent manner （P<0.05， P<0.01）. Compared with the blank group， the volatile oil decreased the cell proliferation and migration （P<0.05， P<0.01） and blocked the AGS cell cycle in G2/M phase （P<0.05， P<0.01） in a concentration-dependent manner. The cells treated with the volatile oil became spherical and smaller， with the formation of apoptotic bodies and increased apoptosis rate （P<0.05， P<0.01）. As the dose of the volatile oil increased， the number of autophagosomes increased and the red fluorescence gradually enhanced， indicating the elevated level of autophagy. Compared with the blank group， different doses of volatile oil up-regulated the protein levels of Beclin-1， LC3 Ⅱ/LC3 Ⅰ， cleaved Caspase-3， cleaved PARP， Bax/Bcl-2， and AMPK （P<0.05， P<0.01） and down-regulated the protein levels of p62 and p-mTOR （P<0.05， P<0.01）. ConclusionThe volatile oil of Linderae Radix induces the apoptosis and exerts the autophagy-mediated growth inhibition of AGS cells by regulating the AMPK/mTOR signaling pathway.

ObjectiveTo screen and establish animal models of combined stasis and toxin syndrome based on the comparison of three modeling methods， i.e.， carrageenan （Ca）， Ca combined with dried yeast （Ca+Yeast）， and Ca combined with lipopolysaccharide （Ca+LPS）. MethodForty SPF male SD rats were randomly divided into normal group， Ca group， Ca+Yeast group， and Ca+LPS group， with 10 rats in each group. The Ca group， Ca+Yeast group， and Ca+LPS group received an intraperitoneal injection of Ca （10 mg·kg-1） on the first day. The Ca+LPS group received an intraperitoneal injection of LPS （50 μg·kg-1） on the second day， and the Ca+Yeast group received a subcutaneous injection of dry yeast suspension （2 mg·kg-1） on the back on the second day. The rectal temperature of each group was dynamically observed after modeling. After 24 hours of modeling， the macroscopic evaluation indexes， including tongue manifestation， pulse， and black tail length in each group were observed. The PeriCam PSI imaging system was used to detect the blood flow perfusion of the rat tail. The automatic hemorheology analyzer was used to measure the whole blood viscosity and plasma viscosity of each group. The PL platelet function analyzer was used to detect the platelet aggregation rate of the rats. The enzyme-linked immunosorbent assay （ELISA） was used to detect the interleukin-6 （IL-6） level in the rat plasma. The myocardial tissue， brain tissue， and lung tissue of each group of rats were observed by hematoxylin-eosin （HE） staining. ResultCompared with the normal group， all three model groups showed varying degrees of black tail （P<0.05， P<0.01）， reduced blood flow perfusion at the tail end （P<0.05， P<0.01）， decreased R， G， and B values of tongue manifestation （P<0.05， P<0.01）， and increased maximum platelet aggregation rate （P<0.05， P<0.01）. The pulse amplitudes of the Ca+Yeast group and the Ca+LPS group were lower than that of the normal group （P<0.05， P<0.01）. In addition， the average rectal temperature of the Ca+Yeast group increased after 24 hours of modeling （P<0.01）， and the low-， medium-， and high-shear whole blood viscosity and plasma viscosity increased （P<0.05， P<0.01） as compared with those in the normal group. Additionally， the expression level of the plasma inflammatory factor IL-6 was significantly up-regulated （P<0.05）. Pathological morphology results showed that the Ca+Yeast group had the most severe pathological changes， with small foci of myocardial fiber dissolution， inflammatory cell infiltration， and fibroblast proliferation observed. In the hippocampal area， the neurons were sparse and had undergone red degeneration. In the small focus of the lung interstitium， lymphocytes and neutrophils were infiltrated. ConclusionThe animal model of combined stasis and toxin syndrome was properly established using Ca+Yeast. The systematic evaluation system of the model， which includes traditional Chinese medicine four diagnostic information， western medicine microscopic indicators， and tissue pathological morphology， is worthy of consideration and reference by researchers.

Perioperative efficacy analysis of robotic surgical system assisted anatomic and non-anatomic hepatectomy / 中华消化外科杂志

Objective:To investigate the perioperative efficacy of robot surgical system assisted anatomic and non-anatomic hepatectomy.Methods:The propensity score matching and retrospective cohort study was conducted. The clinical data of 103 patients who underwent robot surgical system assisted hepatectomy in Sir Run Run Shaw Hospital, Affiliated with the Zhejiang University School of Medicine from March 2016 to December 2021 were collected. There were 54 males and 49 females, aged 56(range, 44?64)years. Of the 103 patients, 55 cases undergoing robot surgical system assisted anatomic hepatectomy were divided into the anatomic group, and 48 cases undergoing robot surgical system assisted non-anatomic hepatectomy were divided into the non-anatomic group. Observation indicators: (1) propensity score matching and comparison of general data of patients between the two groups after matching; (2) intraoperative conditions; (3) perioperative complications. Propensity score matching was done by the 1:1 nearest neighbor matching method. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were expressed as M(range), and comparison between groups was conducted using the Mann-Whitney U test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Comparison of ordinal data was conducted using the rank sum test. Results:(1) Propensity score matching and compari-son of general data of patients between the two groups after matching. Of the 103 patients, 94 cases were successfully matched, including 47 cases in the anatomic group and 47 cases in the non-anatomic group. The elimination of preoperative body mass index, preoperative platelet and preoperative albumin confounding bias ensured comparability between the two groups after propensity score matching. (2) Intraoperative conditions. After propensity score matching, the operation time and volume of intraoperative blood loss were 175(range, 120?240)minutes and 50(range, 50?100)mL in patients of the anatomic group, versus 155(range, 105?190)minutes and 100(range, 50?200)mL in patients of the non-anatomic group, showing significant differences in the above indicators between the two groups ( Z=1.97, 2.49, P<0.05). (3) Perioperative complications. After propensity score matching, cases with pleural fluid and/or ascites, case with biliary fistula, case with thrombosis, case with peritoneal infection, case with incision infection were 11, 1, 2, 4, 1 in patients of the anatomic group, versus 12, 0, 4, 1, 0 in patients of the non-anatomic group, showing no significant difference in the above indicators between the two groups ( P>0.05). Cases with complications classified as grade Ⅰ, grade Ⅱ, grade Ⅲ, grade Ⅳ of the Clavien-Dindo classification were 33, 14, 0, 0 in patients of the anatomic group, versus 28, 14, 3, 2 in patients of the non-anatomic group, showing no significant difference in the above indicators between the two groups ( Z=?1.38, P>0.05). Conclusions:Robotic surgical system assisted anatomic and non-anatomic hepatectomy are safe and feasible for clinical application. Compared with robot surgical system assisted non-anatomic hepatectomy, patients under-going robot surgical system assisted anatomic hepatectomy have long operation time and less volume of intraoperative blood loss.

Of the 807 patients, 173 cases with portal hypertension were divided into the portal hypertension group, and 634 cases without portal hypertension were divided into the non-portal hypertension group. Observation indicators: (1) propensity score matching and comparison of general data of patients between the two groups after matching; (2) intraoperative and post-operative situations; (3) subgroup analysis. Propensity score matching was done by the 1:1 nearest neighbor matching method, with the caliper setting as 0.001. Measurement data with skewed distribution were represented as M( Q1, Q3), and comparison between groups was conducted using the rank sum test. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Comparison of ordinal data was constructed using the non-parameter rank sun test. Results:(1) Propensity score matching and comparison of general data of patients between the two groups after matching. Of the 807 patients, 268 cases were successfully matched, including 134 cases in the portal hypertension group and 134 cases in the non-portal hypertension group. The elimination of the tumor diameter and robot-assisted surgery confounding bias ensured comparability between the two groups after propensity score matching. (2) Intraoperative and postoperative situations. The occlusion time of porta hepatis, cases with intraoperative blood transfusion, cases with postoperative complication, cases with complication >Ⅱ grade of Clavien-Dindo classification, cases of Clavien-Dindo classification as Ⅰ grade, Ⅱ grade, Ⅲ grade, Ⅳ grade, cases with liver related complication were 27.0(15.0,43.0)minutes, 33, 55, 15, 13, 29, 14, 1, 37 in the portal hypertension group, versus 35.0(22.0,60.0)minutes, 17, 25, 5, 14, 9, 4, 1, 13 in the non-portal hypertension group, showing significant differences in the above indicators between the two groups ( Z=-2.15, χ2=6.30, 16.39, 4.38, 20.72, 14.16, P<0.05). (3) Subgroup analysis. Results of subgroups analysis showed that in cases with major live resection, the operation time, volume of intraoperative blood loss, duration of postoperative hospital stay were 243.5(174.6,296.3)minutes, 200.0(150.0,600.0)mL, 7.5(6.0,13.0)days in the portal hypertension group, versus 270.0(180.0,314.5)minutes, 200.0 (75.0,450.0)mL, 7.0(5.5,10.0)days in the non-portal hypertension group, showing no significant difference in the above indicators between the two groups ( Z=-0.54, -1.73, -0.92, P>0.05). In cases with non-major live resection, the operation time, volume of intraoperative blood loss, duration of postoperative hospital stay were 170.0(120.0,227.5)minutes, 100.0(50.0,200.0)mL, 8.0(5.0,10.0)days in the portal hypertension group, versus 170.0(120.0,227.5)minutes, 100.0(50.0,200.0)mL, 7.0(5.5,9.0)days in the non-portal hypertension group, showing no significant difference in the above indicators between the two groups ( Z=-1.39, -0.10, 1.05, P>0.05). In cases with anatomical liver resection, the operation time, volume of intraoperative blood loss, duration of postoperative hospital stay were 210.0(150.0,285.0)minutes, 150.0(50.0,200.0)mL, 8.0(6.0,9.3)days in the portal hypertension group, versus 225.5(146.3,306.8)minutes, 100.0(50.0,250.0)mL, 7.0(6.0,9.0)days in the non-portal hypertension group, showing no significant difference in the above indica-tors between the two groups ( Z=-0.75, -0.26, -0.91, P>0.05). In cases with non-anatomical liver resection, the operation time, volume of intraoperative blood loss, duration of postoperative hospital stay were 173.5(120.0,231.5)minutes, 175.0(50.0,300.0)mL, 7.0(5.0,11.0)days in the portal hyper-tension group, versus 186.0(123.0,262.5)minutes, 100.0(50.0,200.0)mL, 7.0(5.0,9.5)days in the non-portal hypertension group, showing no significant difference in the above indicators between the two groups ( Z=-0.97, -1.12, -0.98, P>0.05). Conclusion:Minimally invasive liver resection or even major liver resection is safe and feasible for screened HCC patients complicated with portal hyper-tension, but attention should be paid to the prevention and treatment of postoperative complications.

Application of microneedle-assisted percutaneous drug delivery system in treatment of rheumatoid arthritis:a review / 中国中药杂志

Rheumatoid arthritis(RA) is a chronic degenerative joint disease characterized by inflammation. Due to the complex causes, no specific therapy is available. Non-steroidal anti-inflammatory agents and corticosteroids are often used(long-term, oral/injection) to interfere with related pathways for reducing inflammatory response and delaying the progression of RA, which, however, induce many side effects. Microneedle, an emerging transdermal drug delivery system, is painless and less invasive and improves drug permeability. Thus, it is widely used in the treatment of RA and is expected to be a new strategy in clinical treatment. This paper summarized the application of microneedles in the treatment of RA, providing a reference for the development of new microneedles and the expansion of its clinical application.
