Objective To study the curative effectiveness of Itraconazole in the treatment of invasive pulmonary aspergillosis following bilateral lung transplantation.Methods One patients undergoing bilateral lung transplantation was readmitted at 8-month postoperatively due to cough, sputum, and fever. Sputum culture reported positive Aspergillus flavus. Chest X-ray manifested bilateral lung infiltration. Chest CT scan showed multiple small cavities. Itraconazole (Sporanox) therapy was performed.Results Sputum smear and culture reported negative aspergillus at sixth of Itraconazole therapy. Patient’s symptoms after Itraconazole treatment for 10 days were improved obviously. Chest CT scan showed the lung lesion still existed. After treatment by Itraconazole, FK506 dosage was decreased from 3 mg, twice a day to 0.5 mg, once a day.Conclusion Pulmonary aspergillosis is an important complication following lung transplantation. Itraconazole therapy can effectively treat invasive pulmonary aspergillosis following bilateral lung transplantation. Blood drug concentration monitoring indicated the dosage of FK506 was significantly decreased after Itraconazole therapy.

Objective To explore the surgical indications and safety of bilateral sequential lung transplantation in 9 cases.Methods Between Jan.2003 to June 2005,9 bilateral sequential lung transplantations were performed in Shanghai Chest Hospital.In 2 cases,the resection and re-transplantation of the second lung was done after ventilation and perfusion in the first lung transplantation.In 6 cases,after the first lung was transplanted,ECMO was established with heparin-bonded circuitry and centrifugal pump and the second lung was transplanted.In 1 case,CPB was used during the transplantation of the second lung.Meanwhile,inhaled nitric oxide(INO) therapy(40 ppm) was performed in 7 cases.Results Severe lung edema occurred in 2 cases,and the patients survived only 12 and 36 h respectively.Six cases with ECMO thereafter rided out the operation successfully.Postoperative days ventilated were 36 to 72 h(mean 48 h).Four patients of them discharged in good conditions and have survived 16,14,11,9 months respectively.One patient died of pulmonary infection and emptysis one month after operation.Another patient died of acute renal failure 3 weeks after operation.The operation performed under the support of CPB was unsuccessful because of heavy hemorrhage and severe acidosis.Conclusions Bilateral sequential lung transplantation is a high risk procedure.ECMO can reduce the risk significantly. Inhaled nitric oxide during and after operation is of benefit to stabilization of hemodynamics and reduce ischemic reperfusion injury.

Objective To detect the proliferation of and production of interferon-γ by drug-specific peripheral T cells from patients with severe drug eruption.Methods Peripheral blood mononuclear cells (PBMCs) were isolated from 10 patients with severe drug eruption,10 patients with mild or moderate drug eruption and 10 normal human controls,stimulated with causative drugs to obtain drug-specific T cells.Then,both PBMCs and drug-specific T cells were stimulated with causative drugs or unrelated drugs followed by the detection of secretion levels of IFN-γ with ex vivo enzyme-linked immunodotting (ELISpot) assay and cultured ELlSpot assav respectively.Results After stimulation with causative drugs,a higher level of IFN-γ was secreted by PBMCs and drug-specific T cells from patients with severe drug eruption compared with those from normal human controls (both P<0.01).and by drug-specific T cells than by PBMCs (P<0.01).The culture with unrelated drugs could neither induce the generation of drug-specific T cells nor promote the secretion of IFN-γ by PBMCs from the patients.Drug-specific T cells still existed in the peripheral blood of 3 patients within 1 to 3 years after recovery of drug eruption.Conclusions There are drug-specific T cells in peripheral blood of patients with severe drug eruption,and they may persist for a certain period of time after recovery of drug eruption.Ex vivo ELISpot combined with cultured ELISpot may be applied to the identification of causative drugs in vivo.

Objective To investigate the clinical manifestation and imaging features of diabetic striatopathy(DS).Methods A retrospective analysis was conducted on the clinical,laboratory,and imaging data of 8 patients with DS,which was then summarized in conjunction with relevant literature.Results Random blood glucose(8.39-24.80 mmol/L)and glycated hemoglobin(HbA1c)(9.0%-21.50%)were elevated in 8 patients.One case had positive urine ketone bodies(++),while 7 cases had negative urine ketone bodies(-).Hemichorea was present in 7 cases,while 1 case did not exhibit hemichorea.A total of 7 cases showed unilateral striatum T1WI hyperintensity on MRI,and 8 cases showed iso/hyper-density on CT scans.Following blood glucose control and other related treatments,involuntary movement disappeared in 2 cases,and symptoms improved in 5 cases.Conclusion DS mainly occurs in diabetic patients with poorly controlled blood glucose,presenting with typical clinical manifestation and neuroimaging features.It manifests exclusively in the contralateral striatum of the affected limb.The diagnosis should be based on a combination of clinical,laboratory,and imaging findings to prevent missed or misdiagnoses.

Heart failure is a group of complex clinical syndromes in the middle and late stages of cardiovascular diseases.Mitochondrial homeostasis imbalance is one of the pathological mechanisms in the occurrence and development of heart failure.This article revolved around the"yin-yang theory"in TCM and explained the pathological mechanism of heart failure through mitochondrial homeostasis.Heart failure is the syndrome of deficiency in nature and excess in superficiality fundamental.Its basic pathogenesis is"yang deficiency and yin excess".Based on the deficiency of heart yang qi and the stagnation of yin pathogens,the combination of deficiency and excess runs through the entire disease.Mitochondrial homeostasis imbalance is a manifestation of yin-yang imbalance at the cellular micro level,mainly manifested as inhibition of mitochondrial biosynthesis,mitochondrial dynamics imbalance,mitophagy disorder,etc.,which affects mitochondrial structure and function and leads to abnormal myocardial energy metabolism.Therefore,based on the"yin-yang theory",the basic treatment method is to"tonify deficiency and damage excess"to regulate mitochondrial biosynthesis,mitochondrial dynamics,and mitophagy,thereby maintaining mitochondrial homeostasis and improving myocardial energy metabolism,which is of great significance for the prevention and treatment of heart failure.

OBJECTIVE：To provide reference for improving TCM treatment of pulmonary nodule. METHODS ：The experience of famous TCM doctors in the TCM treatment of pulmonary nodule was searched by computer ，the formulations of the cases were sorted out ，and the data were recorded into the TCMISS V 2.5 for data analysis ，and the medicine frequency was counted. Apriori algorithm and association rules were used for statistical analysis of core combination of formulations （support degree was 16，confidence degree was 0.65）. Inner core combination and new combination were extracted according to the entropy clustering method of complex system （correlation was 6，penalty was 2）. RESULTS ：A total of 25 literatures were input ，including 64 formulations in total ，166 medicinal materials. For the prescriptions of pulmonary nodule ，the frequency of single ingredient from high to low was Bolbostemma paniculatum ，Glycyrrhiza uralensis ，Astragalus membranaceus ，Prunella vulgaris ，Ostrea gigas，Angelica sinensis ，Pinellia ternate ，Ligusticum chuanxiong ，Mori Corlex ，etc. The main compatibility of the drug model is to invigorate Qi ，dissipate phlegm ，invigorate Qi and activate blood circulation ，and promote Qi and softness ，such as “G. uralensis，B. paniculatum ”“A. membranaceus ，B. paniculatum ”“A. membranaceus ，G. uralensis ”，etc；10 core combinations of the drug were found out ， such as Begonia fimbristipula-Rhodiola rosea-Bupleurum Chinense ， Cervus elaphus Clematis chinensis-Buffalo Horn，etc. There were 5 new prescriptions ，i.e. B. fimbristipula-R. rosea-B. chinense-Setaria italic ，C. elaphus-C. chinensis-Buffalo Horn-French chalk ，A. sinensis-L. chuanxiong-Morus alba- Mori Corlex -P. vulgaris-Ganoderma lucidum ，Hedyotis diffusa-Prunus persica-Trichosanthes kirilowii-Achyranthes bidentata-Eupolyphaga sinensis- Cinnamomi Ramulus ，A. bidentata-E. sinensis-Ephedra sinica-Curcuma aromatica-Curcuma longa-Concretio silicea . CONCLUSIONS ：Most modern doctors believe that the interaction of phlegm and blood stasis is the main pathogenesis of pulmonary nodule ，and the treatment is mainly based on the treatment of lung ，spleen，liver and kidney ，focus on the elimination of symptoms and phlegm ，the elimination of blood stasis and the soft and hard treatment ，pay attention to the weak body of the patient. TCM treatment of pulmonary nodule has a good prospect.

Objective    To assess the early outcome of transapical transcatheter aortic valve replacement (TAVR) for patients with aortic insufficiency. Methods    The patients with aortic valvular disease who underwent transapical TAVR from October 2020 to October 2022 in the Department of Cardiac and Vascular Surgery, the First Affiliated Hospital of Anhui Medical University were enrolled in the current retrospective study. The patients with aortic stenosis were assembled in a group A, and the patients with aortic insufficiency were assembled in a group B. The improvements of heart function and complications were assessed for the two groups. Results    A total of 56 patients were enrolled, including 32 males and 24 females with an average age of 73.34±5.10 years. There were 31 patients in the group A and 25 patients in the group B. There was no statistical difference between the two groups in the age, gender, height, weight, hypertension, coronary artery disease, peripheral vascular disease, chronic obstructive pulmonary disease, renal disorder or classification of heart function (P>0.05). Also, there was still no statistical difference in the rate of permanent peacemaker implants, emergent open surgery, valve re-implants, or perivalvular leakage (P>0.05). After TAVR, the left ventricular diastolic diameter, left ventricular ejection fraction, complicated moderated mitral and tricuspid regurgitation were significantly improved in both groups compared with preoperative findings (P<0.05); however, there was no statistical difference in these parameters between groups (P>0.05). Conclusion    Interventional valve (J-Valve) in the treatment of patients with aortic insufficiency through transapical TAVR significantly improves cardiac function and reduces functional valve regurgitation.

Objective: To evaluate combined robotic and endoscopic surgery in the third space for gastric submucosal tumors(SMTs). Methods: Combined surgery in 4 patients were compared with 19 patients who underwent laparoscopic wedge resection between Aug 2017 and Feb 2018. Results: R₀ resection was achieved in all combined surgery patients. The operation time was longer (112±29 )min vs. (93±11 ) min (t=2.338, P<0.05), but less blood loss, (11±6)ml vs.(59±6)ml (t=15.102, P<0.01). In combined surgery group, there was a larger tumor over resected tissue percentage, 65.4%±28.2% vs.22.8%±19.6% ( t=3.680, P<0.05). Combined surgery group patients were with earlier first breaking wind (3±1.4) d vs.(4.1±0.9) d (t=2.026, P>0.05), and shorter hospital stay (6.5±1.3) d vs.( 8.5±0.6) d (t=4.902, P<0.01), but a little higher hospitalization costs(57 651±10 097)rmb vs.(42 620±5 086)rmb (t=4.508, P<0.01). There were no major postoperative complications occurred in neither groups, nor tumor recurrences after 3-month follow-up. Conclusion Combined robotic and endoscopic surgery in the third space for submucosal gastric tumors is a novel operation with short operation time, less blood loss and good result.

ObjectiveTo study the effect and mechanism of Yixintai on mitochondrial fission proteins in the rat model of chronic heart failure. MethodTen of 60 SD rats were randomly selected as the sham operation group， and the remaining 50 rats were subjected to ligation of the left anterior descending coronary artery for the modeling of heart failure post myocardial infarction. The successfully modeled rats were randomized into model， low-， medium-， and high-dose （1.4， 2.8， and 5.6 g·kg^-1， respectively） Yixintai， and trimetazidine （10 mg·kg^-1） groups. The rats were administrated with corresponding doses of drugs by gavage， and the rats in the model group and sham operation group were given an equal volume of normal saline by gavage for 28 consecutive days. Enzyme-linked immunosorbent assay （ELISA） was then employed to measure the levels of amino-terminal pro-B-type natriuretic peptide （NT-pro BNP）， B-type natriuretic peptide （BNP）， and adenosine triphosphate （ATP） in the serum. Color Doppler ultrasound imaging was conducted to examine the cardiac function indicators. Hematoxylin-eosin staining and Masson staining were conducted to observe the pathological changes in the heart， and Image J was used to calculate collagen volume fraction （CVF）. Transmission electron microscopy was employed to observe the ultrastructural changes of myocardial cells. Terminal-deoxynucleoitidyl transferase-mediated nick-end labeling （TUNEL） was employed to measure the apoptosis rate of myocardial cells. Western blot was employed to determine the protein levels of mitochondrial fission protein 1 （Fis1） and mitochondrial fission factor （Mff） in the outer mitochondrial membrane of the myocardial tissue. ResultCompared with the sham operation group， the model group showed elevated levels of NT-pro BNP and BNP in the serum， decreased ATP content， left ventricular ejection fraction （LVEF）， and left ventricular fraction shortening （LVFS）， increased left ventricular end-diastolic diameter （LVIDd） and left ventricular end-systolic diameter （LVIDs）， disarrangement of myocardial cells， inflammatory cell infiltration， increased collagen fibers and CVF， damaged myocardium and mitochondria， and increased apoptosis rate of myocardial cells， and up-regulated expression of Fis1 and Mff in the cardiac tissue （P<0.01）. Compared with the model group， different doses of Yixintai and trimetazidine lowered the serum levels of NT-pro BNP and BNP （P<0.05）， increased the ATP content （P<0.05）， increased LVEF and LVFS （P<0.01）， decreased LVIDd and LVIDs （P<0.01）. Moreover， the drugs alleviated the myocardial inflammatory damage and fibrosis， reduced CVF （P<0.01）， repaired the myocardial mitochondrial structure， and decreased the apoptosis rate of myocardial cells （P<0.01）. Medium- and high-dose Yixintai and trimetazidine down-regulated the expression of Fis1 and Mff in the myocardial tissue （P<0.05）. ConclusionYixintai can improve mitochondrial structure， reduce myocardial cell apoptosis， and improve cardiac function by inhibiting the expression of Fis1 and Mff in the myocardial tissue.
