ABSTRACT

In this experiment, an ultra-high performance liquid chromatographytandem triple quadrupole mass spectrometry was established for the determination of caffeine in commercially available Ginkgo Folium. The samples were extracted by ultrasonic method with methanol, and separated on Waters CORTECS T3 column(2.1 mm×100 mm, 2.7 μm), with mobile phase of 0.1% formic acid solution-0.1% formic acid acetonitrile solution for gradient elution, at flow rate of 0.3 mL·min~(-1); column temperature of 30 ℃, and injection volume of 2 μL. Mass spectrometry was conducted at ESI~+ multiple reaction monitoring(MRM) mode; quantitative analysis was conducted with external standard method. The results showed that in the range of 0.099 6-9.96 ng·mL~(-1), there was a good linear relationship between the mass concentration of caffeine and the peak area, R~2=0.999; the average recovery was 84.51%, with RSD of 6.2%. The results of precision, repeatability and stability showed that the RSD was 5.1%, 5.9%, 7.2%, respectively. The content range of caffeine in 10 batches of Ginkgo Folium was 1.52-60.86 μg·kg~(-1). In conclusion, this method is accurate, reliable and reproducible, which provides a reference for the safety study of Ginkgo Folium.

ABSTRACT

Heart transplantation can save the life and improve the quality of life of patients with end-stage heart failure. Nevertheless, it is not suitable for all patients with end-stage heart failure. As a common complication of end-stage heart failure, pulmonary artery hypertension may increase the incidence of right heart failure after heart transplantation, which is associated with the short- and long-term fatality risk in the recipients after heart transplantation. In clinical practice, different transplant centers have different criteria for heart transplantation indications in patients with end-stage heart failure complicated with pulmonary artery hypertension. Accurate preoperative evaluation of surgical indications plays a critical role in determining the success of heart transplantation. In this article, the definition, pathogenesis and effects on heart transplantation, diagnostic methods and reversibility judgment of pulmonary artery hypertension, diagnostic treatment of reversible pulmonary artery hypertension and indications of heart transplantation in patients with end-stage heart failure complicated with reversible pulmonary hypertension were reviewed.

ABSTRACT

Objective:To retrospectively analyze the data of patients undergoing extracorporeal membrane oxygenation (ECMO) during perioperative period of cardiac transplantation and provide objective and reliable evidence for further clinical promotion.Methods:Collect the clinical data of patients undergoing heart transplantation and ECMO support in Fuwai Hospital, analyze the duration of ECMO support, combined use of aortic balloon counterpulsation (IABP), and complications during the supporting period. All statistical analyses were processed by SPSS 23.0 software. Independent sample Student's test was employed for normal distribution and Mann-Whitney U test for abormal distribution. χ2 or Fisher exact test was utilized for comparinge the classification data between groups. Results:All ECMO support models were intravenous-arterial ECMO (V-A ECMO). Eight patients successfully bridging heart transplantation through VA-ECMO. Sixty-one patients (89.7%) who had undergone cardiac transplantation were successfully weaned from ECMO while 48 patients (70.5%) survived and discharged. The most common complications during circulation support are bleeding, acute renal insufficiency, and pulmonary infection. Patients with ECMO support in the operating room had a better rate of survival and weaning off(95.6%, 84.4%) than those with ECMO at the bedside of ICU(72.2%, 27.8%).Conclusions:ECMO can provide adequate circulation and respiratory function support for heart transplant patients, and it is an indispensable treatment for patients to go through the perioperative period of heart transplant surgery smoothly. It is advocated to use IABP combined with ECMO in the early stage and at the same time to increase the perfusion of vital organs, improve the prognosis of patients and obtain good outcomes.

ABSTRACT

Objective To analyze the early outcomes of heart transplantation in critical patients and its significance in donor allocation decision. Methods Clinical data of 449 recipients undergoing heart transplantation were retrospectively analyzed. According to preoperative status, all patients were divided into the critical status group (n=64) and general status group (n=385). The incidence of critical status was summarized. Clinical data of recipients were statistically compared between two groups. Postoperative survival and causes of death in recipients between two groups were analyzed. Perioperative results of critical recipients undergoing different mechanical circulation support as a bridge to heart transplantation were compared. Results Critical patients accounted for 14.3% of the total number of transplant recipients. The proportion of critical patients gradually increased in recent 5 years. Compared with the general status group, the recipients in critical status group had a lower proportion of smoking history, a higher proportion of cardiac surgery history, a higher serum level of creatinine, and a higher proportion of primary diseases of heart failure before heart transplantation(all P≤0.01). The proportion of undergoing mechanical circulation support was higher, the incidence of complications was higher, the stay time in intensive care unit (ICU) was longer and the in-hospital fatality was higher after heart transplantation in the critical status group (all P≤0.01). The 1-year survival rate of recipients in critical status group was significantly lower than that in general status group (83% vs. 95%, P < 0.01). The fatality of recipients due to infection and multiple organ failure in critical status group was higher than that in general status group. Among 64 critical recipients, 1 recipient received ventilator alone, and 63 recipients underwent mechanical circulation support devices as a bridge to heart transplantation. Among them, intra-aortic balloon pump (IABP) alone was applied in 49 cases (77%), 8 cases (13%) of extracorporeal membrane oxygenation (ECMO) combined with IABP, 4 cases (6%) of ECMO alone, and 2 cases (3%) of left ventricular assist device (LVAD) alone. Critical patients who received preoperative ECMO and ECMO combined with IABP bridging to heart transplantation have a higher proportion of postoperative complications, a longer ICU stay time, a longer mechanical ventilation time, and a higher proportion of hospital deaths. Conclusions The overall prognosis of critical patients undergoing heart transplantation is relatively poor. Effective preoperative management may reverse the high-risk status of critical patients in a certain extent. The limited quantity of donor heart should be allocated to the most urgent patients who can obtain the greatest benefit from heart transplantation.

ABSTRACT

BACKGROUND@#Shenyankangfu Tablet (SYKFT) is a Chinese patent medicine that has been used widely to decrease proteinuria and the progression of chronic kidney disease.@*OBJECTIVE@#This trial compared the efficacy and safety of SYKFT, for the control of proteinuria in primary glomerulonephritis patients, against the standard drug, losartan potassium.@*DESIGN, SETTING, PARTICIPANTS AND INTERVENTION@#This was a multicenter, double-blind, randomized, controlled clinical trial. Primary glomerulonephritis patients, aged 18-70 years, with blood pressure ≤ 140/90 mmHg, estimated glomerular filtration rate (eGFR) ≥ 45 mL/min per 1.73 m@*MAIN OUTCOME MEASURES@#The primary outcome was change in the 24-hour proteinuria level, after 48 weeks of treatment.@*RESULTS@#A total of 735 participants were enrolled. The percent decline of urine protein quantification in the SYKFT group after 48 weeks was 8.78% ± 2.56% (P = 0.006) more than that in the losartan 50 mg group, which was 0.51% ± 2.54% (P = 1.000) less than that in the losartan 100 mg group. Compared with the losartan potassium 50 mg group, the SYKFT plus losartan potassium 50 mg group had a 13.39% ± 2.49% (P < 0.001) greater reduction in urine protein level. Compared with the losartan potassium 100 mg group, the SYKFT plus losartan potassium 100 mg group had a 9.77% ± 2.52% (P = 0.001) greater reduction in urine protein. With a superiority threshold of 15%, neither was statistically significant. eGFR, serum creatinine and serum albumin from the baseline did not change statistically significant. The average change in TCM syndrome score between the patients who took SYKFT (-3.00 [-6.00, -2.00]) and who did not take SYKFT (-2.00 [-5.00, 0]) was statistically significant (P = 0.003). No obvious adverse reactions were observed in any group.@*CONCLUSION@#SYKFT decreased the proteinuria and improved the TCM syndrome scores of primary glomerulonephritis patients, with no change in the rate of decrease in the eGFR. SYKFT plus losartan potassium therapy decreased proteinuria more than losartan potassium therapy alone.@*TRIAL REGISTRATION NUMBER@#NCT02063100 on ClinicalTrials.gov.

ABSTRACT

Inflammatory bowel disease (IBD) has become a global disease with accelerating incidence worldwide in the 21st century while its accurate etiology remains unclear. In the past decade, gut microbiota dysbiosis has consistently been associated with IBD. Although many IBD-associated dysbiosis have not been proven to be a cause or an effect of IBD, it is often hypothesized that at least some of alteration in microbiome is protective or causative. In this article, we selectively reviewed the hypothesis supported by both association studies in human and pathogenesis studies in biological models. Specifically, we reviewed the potential protective bacterial pathways and species against IBD, as well as the potential causative bacterial pathways and species of IBD. We also reviewed the potential roles of some members of mycobiome and virome in IBD. Lastly, we covered the current status of therapeutic approaches targeting microbiome, which is a promising strategy to alleviate and cure this inflammatory disease.

ABSTRACT

Objective To improve the understanding of Danon disease and the efficacy of heart transplantation by multi-disciplinary team (MDT) pattern. Methods Prior to heart transplantation, MDT consultation was performed on one case of Danon disease, an extremely rare X-chromosome dominant genetic disease. The content of consultation included surgical indication, preoperative preparation and postoperative precaution, as well as the role of MDT in the treatment of Danon disease was summarized. Results Preoperative echocardiography showed that the patient presented withdilated-phase of hypertrophic cardiomyopathy complicated with heart failure, which was considered as Danon disease with end-stage heart failure. After MDT consultation, the patient received the preoperative treatment including anti-heart failure, reduction of pulmonary artery pressure, intra-aortic balloon pump (IABP) assistance, liver protection, strengthening nutritional support, etc. The patient underwent orthotopic heart transplantation after a suitable donor was matched. The patient developed muscle weakness in the limbs 5 days after operation, which was gradually mitigated after reducing the dose of glucocorticoid. At postoperative 48 days, the patient was discharged in good condition and continually treated with triple immunosuppressive regimen after discharge. Reexamination at postoperative 6 months revealed that the patient was in good health without any abnormality in electrocardiogram and echocardiography images. Conclusions Danon disease is extremely rare and MDT pattern may enhance the efficacy and safety of treatment by heart transplantation.

ABSTRACT

The arachidonic acid (AA) metabolic pathway participates in various physiological processes as well as in the development of malignancies. We analyzed genomic alterations in AA metabolic enzymes in the Cancer Genome Atlas (TCGA) prostate cancer (PCa) dataset and found that the gene encoding soluble epoxide hydrolase (EPHX2) is frequently deleted in PCa. EPHX2 mRNA and protein expression in PCa was examined in multiple datasets by differential gene expression analysis and in a tissue microarray by immunohistochemistry. The expression data were analyzed in conjunction with clinicopathological variables. Both the mRNA and protein expression levels of EPHX2 were significantly decreased in tumors compared with normal prostate tissues and were inversely correlated with the Gleason grade and disease-free survival time. Furthermore, EPHX2 mRNA expression was significantly decreased in metastatic and recurrent PCa compared with localized and primary PCa, respectively. In addition, EPHX2 protein expression correlated negatively with Ki67 expression. In conclusion, EPHX2 deregulation is significantly correlated with the clinical characteristics of PCa progression and may serve as a prognostic marker for PCa.

ABSTRACT

@#Objective    To summarize the clinical characteristics and the long-term results of pulmonary thromboendarterectomy (PTE) in the chronic thromboembolic pulmonary hypertension (CTEPH) patients with unilateral main pulmonary artery occlusion. Methods    We retrospectively analyzed the clinical data of 15 CTEPH patients with unilateral main pulmonary artery occlusion in Fuwai Hospital between 2004 and 2018. There were 11 males and 4 females aged 34.1±12.0 years at operation. Results    The mean circulatory arrest was 31.1±12.1 minutes. The ICU stay was 5 (2-29) d. The hospital stay was 15 (8-29) d. There was no hospital death. There was a decline in systolic pulmonary artery pressures (sPAP, 69.9±27.9 mm Hg to 35.1±9.7 mm Hg, P=0.020) after surgery. On postoperative V/Q scan, only 6 patients (40.0%) had significant improvement in reperfusion (≥75% estimated) of the occluded lung. There was no death during the median observation period of 49 months follow-up, while 2 patients had recurrence of pulmonary embolism. Conclusion    CTEPH patients with unilateral main pulmonary artery occlusion represent a challenging cohort. PTE is a curative resolution in both early- and long- term results, although there is a high requirement of perioperative management and a high risk of postoperative complications and rethrombosis.

ABSTRACT

ObjectiveThe assessment of volume load status in patients with acute heart failure is of great significance for preventing volume overload. The aim of this study was to explore the predictive value of NT-proBNP level and IVC-CI on volume load and prognosis in patients with acute heart failure. MethodsFrom January 2017 to April 2019, the clinical characteristics of 98 patients with acute heart failure diagnosed and treated in the Peking University People's Hospital were retrospectively reviewed in this study. All of them were treated with routine anti-heart failure treatment. According to the level of relative volume balance, they were divided into volume overload group (65 cases) and non-volume overload group (33 cases). All the patients were followed up for 30 days after discharge. The patients with death and cardiogenic rehospitalization were included in the event group (30 cases), and the rest were in the non-event group (68 cases). NT-proBNP and IVC-CI in different volume load groups and different prognosis groups were compared. The volume index levels (serum albumin, hemoglobin, hematocrit, PCWP, CVP) of patients in different volume load groups were compared. The effects of NT-proBNP and IVC-CI on volume load and prognosis of patients were analyzed.ResultsThe levels of NT-proBNP [(1306.39±313.98)pg/mL], PCWP [(19.63±1.95)mmHg] and CVP [(14.65±1.03)cmHg] in the volume overload group were higher than those in the non-volume overload group, while the IVC-CI [(38.26±8.14)%], albumin [(16.23±2.12)g/L], hemoglobin and hematocrit [(36.26±2.78)%] in the volume overload group were lower than those in the non-volume overload group (P0.05). On discharge, the AUC of NT-proBNP, IVC-CI in predicting patients with acute heart failure was respectively 0.806 and 0.847. Although the prediction accuracy was relatively high, the AUC of combined prediction was 0.982, which was significantly higher than that of NT-proBNP and IVC-CI (Z=3.589, 3.274, both P<0.05).Conclusion There is a correlation between NT-proBNP, IVC-CI and volume indexes. The combined detection of NT-proBNP and IVC-CI can help to assess the volume load status of patients with acute heart failure and improve the predictive value of short-term prognosis of patients.

ABSTRACT

Objective Transdifferentiation exists between stromal cells or between stromal cells and cancer cells. Evodiamine and berberine are predominant pharmacological components of pill, a prescription of Traditional Chinese Medicine, playing crucial functions in remolding of tumor microenvironment. This study aimed to explore the effect of combination of evodiamine with berberine (cBerEvo) on the phenotypic transition of colon epithelial cells induced by tumor-associated fibroblasts, as well as the involved mechanisms.Methods Human normal colon epithelial cell line HCoEpiC cells were treated with the prepared conditioned medium of CCD-18Co, a human colon myofibroblast line, to induce epithelial-mesenchymal transition. Phase contrast microscope was used to observe the morphological changes. Epithelial-mesenchymal transition markers including E-cadherin, vimentin and alpha-smooth muscle actin (α-SMA) were observed with immunofluorescence microscopy. Migration was assessed by wound healing assay. Western blotting was used to detect the expressions of E-cadherin, vimentin, α-SMA, Snail, ZEB1 and Smads. Results In contrast to the control, the tumor-associated fibroblasts-like CCD-18Co cells induced down-regulation of E-cadherin and up-regulation of vimentin, α-SMA, Snail and ZEB1 (<0.05), and promoted migration of HCoEpiCs (<0.05), with over expression of Smads including Smad2, p-Smad2, Smad3, p-Smad3 and Smad4 (<0.05), which were abolished by a transforming growth factor-β (TGF-β) receptor inhibitor LY364947 and by cBerEvo in a concentration dependent manner. In addition, cBerEvo-inhibited ratios of p-Smad2/Smad2 and p-Smad3/Smad3 were also dose dependent.Conclusion The above results suggest that cBerEvo can regulate the differentiation of colon epithelial cells induced by CCD-18Co through suppressing activity of TGF-β/Smads signaling pathway.

ABSTRACT

To investigate the safety and feasibility of longitudinal transpancreatic U-sutures invaginated pancreatojejunostomy (Chen's pancreaticojejunostomy technique) in laparoscopic pancreaticoduodenectomy (LPD). Clinical data of 116 consecutive patients who underwent LPD using Chen's pancreaticojejunostomy technique in Hunan Provincial People's Hospital from May 2017 to December 2018 were retrospectively analyzed. Among these patients, 66 were males and 50 were females. The median age was 58 years old (32-84 yeas old). All 116 patients underwent pure laparoscopic whipple procedure with Child reconstruction method, using Chen's pancreaticojejunostomy technique. The intraoperative and postoperative data of patients were analyzed. All 116 patients underwent LPD successfully. The mean operative time was (260.3±33.5) minutes (200-620 minutes). The mean time of pancreaticojejunostomy was (18.2±7.6) minutes (14-35 minutes). The mean time of hepaticojejunostomy was (14.6±6.3) minutes (10-25 minutes). The mean time of gastrojejunostomy was (12.0±5.5) minutes (8-20 minutes). The mean estimated blood loss was (106.0±87.6) ml (20-800 ml). Postoperative complications were: 11.2%(13/116) of cases had postoperative pancreatic fistula (POPF), including 10.3% (12/116) of biochemical fistula and 0.9%(1/116) of grade B POPF, no grade C POPF occurred; 10.3%(12/116) had gastrojejunal anastomotic bleeding; 3.4%(4/116) had hepaticojejunal anastomotic fistula; 3.4%(4/116) had delayed gastric emptying; 4.3% (5/116) had localized abdominal infection; 12.1%(14/116) had pulmonary infection; postoperative mortality were 0(0/116) and 1.7%(2/116) within 30 days and 90 days, respectively. One patient died of massive abdominal bleeding secondary to Gastroduodenal artery pseudoaneurysm rupture, the other patient died of extensive tumor recurrence and metastasis after surgery. Chen's pancreaticojejunostomy technique is safe and feasible for LPD.It is an option especially for surgeons who have not completed the learning curve of LPD.

ABSTRACT

Objective::To observe the clinical efficacy of Duhuo Xuduan Tang for oral administration and iontophoresis in the treatment of knee osteoarthritis (KOA) with liver and kidney deficiency and its effect on stromal cell-derived factor-1 (SDF-1)/C-X-C chemokine receptor type 4 (CXCR4) signaling pathway. Method::Totally 150 KOA patients with deficiency of liver and kidney diagnosed in the Teaching Hospital of Tianjin University of Traditional Chinese Medicine(TCM) were randomly divided into control group, oral TCM group and iontophoresis group, with 50 cases in each group. The control group was given glucosamine sulfate capsule, 0.5 g/time, twice a day, while the oral TCM group was given Duhuo Xuduan Tang, 150 mL/time, twice a day. In the iontophoresis group, Duhuo Xuduan Tang was administered at Kuangu acupoint, Xiguan acupoint, Xiyan acupoint and Dubi acupoint for iontophoresis for 30 minutes, once a day. All of the three groups were treated for 4 weeks. The swelling degree and the pain degree of knee joint before and after treatment were observed, and the clinical efficacy was recorded. The protein contents of SDF-1, CXCR4, matrix metalloproteinase-3 (MMP-3) and matrix metalloproteinase-13 (MMP-13) in knee joint fluid before and after treatment were detected by enzyme-linked immunosorbent assay (ELISA). Result::The efficacy of oral TCM group was better than that of iontophoresis group and control group, and the recurrence rate was the lowest (P<0.05). Compared with before treatment, the tenderness increased, whereas visual analogue scale(VAS) score, knee swelling score, The Western Ontario and McMaste Universities (WOMAC) score and SDF-1, CXCR4, MMP-3 and MMP-13 protein content in knee joint fluid decreased in oral TCM group after treatment, which were better than those in iontophoresis group and control group (P<0.05). Conclusion::Duhuo Xuduan Tang for oral administration and iontophoresis has an obvious effect on KOA with liver and kidney deficiency, with the best effect through oral administration. Its mechanism may be related to the inhibition of SDF-1/CXCR4 inflammatory signaling pathway and cartilage decomposition.

ABSTRACT

Objective:To observe the clinical efficacy of addition and subtraction therapy of Shashen Maidongtang for syndrome of Yin deficiency and lung heat at convalescent period in patients with mycoplasma pneumoniae pneumonia, and to investigate its regulatory effect on immune inflammatory response. Method:One hundred and forty-eight patients were randomly divided into control group (74 cases) and observation group (74 cases) by random number table. During the treatment, 70 patients completed the study in control group (loss to follow-up in 2 cases, elimination in 3 cases), and 71 patients completed the study in observation group (loss to follow-up in 4 cases). Patients in both groups got Azithromycin tablets for 3 days, 10 mg·kg-1·d-1, pidotimod granules, 0.4-0.8 g/time, 2 times/day, and Ambroxol oral solution, 2.5-15 mL/time, 2 times/day. The patients in control group additionally received Yangyin Qingfei oral liquid, 5-10 mL/time, 2-3 times/day, while the patients in observation group additionally received addition and subtraction therapy of Shashen Maidongtang, 1 dose/day, with a treatment course of 7 days in both groups. Before and after treatment, scores of cough symptom and cough visual analogue score (VAS) were graded, and the time to disappearance of cough, lung rales and expectoration as well as the time to recovery of chest radiograph were recorded. Scores of syndrome of yin deficiency and lung heat and Leicester Cough Questionnaire (LCQ) were also graded. Levels of T lymphocyte subsets (CD3+, CD4+, CD8+ and CD4+/CD8+), interleukin-6 (IL-6), IL-10, tumor necrosis factor-α (TNF-α), substance P (Substance P) and procalcitonin gene related peptide (CGRP) were detected, and the safety was also evaluated. Result:Total effective rate for the disease was 95.77% (68/71) in observation group, higher than 82.86% (58/70) in control group (χ2=6.186, P<0.05). Scores of cough symptoms and VAS were higher than those in control group (P<0.01), and scores of various items in LCQ scale and the total score of LCQ were all higher than those in control group (P<0.01). The time to disappearance of cough, lung rales and expectoration as well as the time to recovery of chest radiograph in observation group were shorter than those in control group (P<0.01). Levels of CD3+, CD4+ and CD4+/CD8+ were higher than those in control group (P<0.01), and levels of CD8+, IL-6, IL-10, TNF-α, SP in serum and CGRP in sputum were all lower than those in control group (P<0.01). Conclusion:On the basis of conventional western medicine treatment, addition and subtraction therapy of Shashen Maidongtang can reduce the degree of cough, shorten the course of disease, improve the quality of life, improve the cellular immune function, reduce the inflammatory injury, and reduce the sensitivity of cough, with better clinical efficacy and safety as compared with Western medicine alone.
