Objective This study was conducted to investigate the clinical outcomes and safety of percutaneous coronary intervention (PCI) to the single-opened vessel lesion among patients with severe left ventricular systolic dysfunction. Methods Twenty-seven patients with severe left ventricular systolic dysfunction (ejection fraction≤35%) undergoing PCI were included. All the patients received PCI only to the single-opened vessel lesion under the conditions of: (1) There were limitations to open chronic total occlusion (CTO);(2) Single-opened vessel lesion was not calcified and tortuous. Clinical outcomes, including success rate of PCI, changes of symptoms in-hospital, brain natriuretic peptide (BNP) and left ventricular ejection fraction (LVEF) pre-and one week post-PCI, the major adverse cardiac events (MACE, including death, myocardial infarction and target vessel revascularization) at 30-days after discharged were observed. Results The success rate of PCI was obtained in all 27 patients(100%), and all the patients received drug eluting stent implantation. The symptoms improvement occurred in all patients and the NYHA class improved from grade Ⅳto grade Ⅲin 22 patients(81.5%) in-hospital. Significant differences were noted in the mean BNP and LVEF between pre-PCI and one week post-PCI, BNP[(2699.6±1104.7) pg/ml vs. (737.0 ± 261.7) pg/ml, P<0.05],LVEF[(26.9±5.7)%vs. (36.0±3.41)%, P<0.05)]. No MACE happened in-hospital and at 30-days follow up. Conclusions PCI only to the single-opened vessel lesion among patients with severe left ventricular systolic dysfunction under the condition of limitations to open CTO is safe and can significantly improve clinical outcomes in-hospital and at 30-days follow up, but it must be emphasized that single-opened vessel lesion not with obvious calcification and tortuosity.

Objective:To investigate the associations between the hormone receptors,Ki67 expression and response to neoadjuvant anthracycline-based chemotherapy in breast cancer patients.Methods:One hundred sixty-eight primary breast cancer patients received anthracycline-based neoadjuvant chemotherapy.The expression of estrogen receptor(ER),progesterone receptor(PR),and Ki67 were determined by immunohistochemistry assay in core-needle biopsy specimens prior to the chemotherapy,and pathologic response was assessed by Miller & Payne grade(G1 to G5).Results:40%(67/168)of the patients had a good pathologic response,defined as complete pathologic response(pCR or G5)and minimal residual disease(G4).Among the patients,20%(33/168)had a complete pathologic response(G5).ER or PR status was significantly associated with pathological response.Patients with PR-negative tumors had a higher pathological response rate or pCR than those with PR-positive tumors(17/67 vs 45/90,P=0.002;6/67 vs 25/90,P=0.003,respectively),whereas patients with ER-negative tumors had a higher pathological response rate than those with ER-positive tumors.Moreover,Patients with both ER-and PR-negative tumors exhibited a remarkable pathological response as compared with those with any single factor(36/17 vs 26/86,P=0.009).No association between Ki67 expression and pathological was found in this cohort of patients.There was a linear correlation between the expression of Ki-67,ER or PR status and pathologic response.Conclusion:There is a significant association between the hormone receptors and pathological response to neoadjvant anthracycline-based chemotherapy in breast cancer patients,and patients with PR-negative tumors are more likely to respond to chemotherapy.

OBJECTIVETo establish the model of microdialysis, and study the ocular pharmacokinetics of puerarin in anesthetic rabbits.

METHODImplanted the probe into anterior chamber of anesthetic rabbit by surgery. After balanced for 2 h, 1% puerarin eye drop (100 microL) was applied into the cul-de-sac with micropipette. Immediately the dialysate was collected at different time and detected by HPLC with the detection wavelength of 249 nm. The mobile phase was methanol and 0.1% citric acid solution (30:70); the flow rate was 1.0 mL x min(-1).

RESULTAfter the administration, puerarin can be absorbed into aqueous humor quickly. The peak concentration of puerarin appeared at about 1 h and then reduced gradually. The peak concentration(C(max)) is (2.52 +/- 0.31) mg x L(-1). The other lower peak was shown at 3.5 h during the eliminate phase. This might be attributed to the inhibition of aqueous humor production by the puerarin and resulted in a high drug concentration. The area under concentration-time curve (AUC(0-t)) is (5.04 +/- 0.21) mg x h x L(-1) and the eliminate half life (t1/2) is (0.38 +/- 0.13) h.

CONCLUSIONThe microdialysis technique can be used to detect the ocular pharmacokinetics of puerarin, and support the valuable pharmacokinetics parameter for the clinical applications of puerarin eye drop.

Freshwater crabs (Sinopotamon denticulatum) were examined for metacercariae. Cats and dogs were also examined for Paragonimus infection. Questionnairing was carried out on health knowledge and behaviors among local residents in a village of Baokang County, Hubei Province. Results showed that the infection rate of Paragonimus skrjabini metacercariae in Sinopotamon denticulatum was 20.5% (46/214), with 15.6% (20/128) in a mining area and 30.2%(26/86) for the non-mining area respectively ( ?2=6.5, P0.05). Questionnairing showed that dogs and cats were with the habit of foraging and defecating at streams and children had the habits of eating raw or under-cooked crabs. The natural and ecological environments are in favor of the life cycle of P. skrjabini.

Objective To investigate the clinical, radiological and pathological characteristics, treatment and prognosis of pulmonary benign metastasizing leiomyoma (PBML). Methods The clinical and image data of 6 patients with PBML confirmed by pathology from October 2012 to December 2016 were retrospectively analyzed, and the related literature was reviewed. Results Six cases were female, age was from 32 to 55 (43.80 ± 7.17) years. Two cases were found by physical examination, 2 cases had chest distress and asthma, 1 case had chest pain, and 1 case had hemoptysis. Pulmonary abnormalities were detected between 1 month and 15 years after uterine myomectomy. Chest CT showed that multiple lung nodules or masses were observed in 5 patients, among which random distribution was in 3 cases, diffuse military nodule pattern was in 2 cases, and single mass combined with primary lung adenocarcinoma was in 1 case. Fluorine-18-fluorodeoxyglucose positron emission tomography/CT (18F- FDG PET/CT) of one patient showed no obvious uptake of the maximum standardized uptake value. All patients were confirmed histologically with CT guided lung biopsy (2 cases), thoracoscopic lung biopsy (2 cases), and thoracoscopic lobectomy with wedge resection (2 cases). Tumor cells revealed the characteristics of smooth muscle cell differentiation. Immunohistochemistry showed strong positive express of Desmin, SMA smooth muscle specific markers, estrogen receptor and progesterone receptor. Three patients were treated with oral tamoxifen anti estrogen therapy with follow-up from 5 months to 5 years. Four cases had a good prognosis, and 2 cases were lost in follow-up. Conclusions PBML is a rare disease that is prone to occur in women of childbearing age. The clinical symptoms are atypical. Imaging examination and pathology are necessary for diagnosis. Surgery combined with endocrine therapy is effective.

Objective To investigate the predictors of early neurological deterioration (END) after intravenous thrombolysis in patients with acute ischemic stroke and its impact on short-term outcomes. Methods From January 2017 to April 2019, patients with acute ischemic stroke treated with intravenous thrombolysis in the Second Affiliated Hospital of Xuzhou Medical University were enrolled retrospectively. END was defined as the National Institutes of Health Stroke Scale (NIHSS) score within 7 days after admission increased by ≥2 compared with the baseline. The short-term outcomes were evaluated by the modified Rankin Scale at discharge. 0-2 was defined as good outcomes and 3-6 was defined as poor outcomes. Multivariate logistic regression analysis was used to determine the independent predictors of END and their correlation with short-term outcomes. Results A total of 199 patients with acute ischemic stroke received intravenous thrombolysis were enrolled. The median age was 68 years (interquartile range: 62- 76 years), 69 were women (34. 7％), and the baseline median NIHSS score was 6 (interquartile range: 3- 12). END occurred in 35 patients (17. 6％). Symptom progression occurred mainly 2 days after admission (31 patients, 88. 6％). Most of the causes of END were ischemic progression or recurrence (28 patients, 80. 0％). The univariate analysis showed that fasting blood glucose and symptomatic intracranial hemorrhage were associated with END (all P < 0. 05). However, multivariate logistic regression analysis did not find independent predictors of END. Excluding 12 patients with missing short-term outcome data, a total of 187 patients were included in the short-term outcome analysis. Among them, 110 patients had good outcomes and 77 had poor outcomes. Univariate analysis showed that ischemic heart disease, atrial fibrillation, mild stroke, etiological classification, baseline NIHSS score, absolute lymphocyte count, fasting blood sugar, neutrophil/lymphocyte ratio, whether to receive interventional therapy, and END were correlated with short-term outcomes (all P < 0. 05 ). Multivariate logistic regression analysis indicated that high baseline NIHSS score (odds ratio 1. 350, 95％ confidence interval 1. 182-1. 541; P < 0. 001) and END (odds ratio 32. 540, 95％ confidence interval 6. 149- 172. 21; P < 0. 001 ) were the independent risk factors for short-term poor outcomes. Conclusions END still occurs in some patients after intravenous thrombolysis for acute ischemic stroke, and END is an independent risk factor for short-term poor outcomes.
