Objective To investigate the risk factors and prognosis of no-reflow phenomenon in patients after percutaneous coronary intervention(PCI).Methods Retrospectively analyzed 524 patients with acute coronary syndrome after PCI of which 427 patients had detailed record.Angiographic no-reflow phenomenon was designated as TIMI≤2 flow without mechanical obstruction of embolism,thrombus,dissection and spasm.Normal flow designated as TIMI 3 flow.Using random count table of Excel,70 patients were randomized from 393 patients with coronary flow TIMI 3 after PCI as the control normal flow group.Results The no reflow group enrolled 34 patients.Compared with the normal flow group,their incidence of AMI and diabetes,the blood insulin level and mean leukocyte count were significantly higher.The incidence of MACE in and out of hospital was higher in the no reflow group than the normal flow group.Within the no reflow group,the EF decreased while the LVEDD increased significantly PCI.Conclusion History of diabetes,blood insulin level and leukocyte count may be the risk factors of no-reflow.On the other hand,the no reflow phenomenon maybe a prognostic factor of MACE,ventricular remodeling and heart function for patients after PCI.

Objective To study whether Hirsutella sinensis (HS) can antagonize aristolochic acid (AA) induced fibrogenesis on human proximal tubular epithelial cells (HKC). Methods HKC were incubated with medium alone, medium with HS 10 mg/L, medium with AA-Na 40 mg/L or medium with AA-Na 40 mg/L and HS 10 mg/L, respectively. After 12 h (for mRNA) or 36 h (for protein) ,cells were lysed,and the mRNA and protein expression level of transforming growth factor-?1 (TGF-?1), connective tissue growth factor (CTGF), tissue inhibitor of metalloproteinase-1 (TIMP-1)and plasminogen activator inhibitor-1 (PAI-1) of HKC were measured by RT-PCR, ELISA (for TGF-?1, TIMP-1 and PAI-1) and Western blotting (for CTGF), respectively. Results The mRNA and protein expression of TGF-?1, PAI-1, CTGF and TIMP-1 were significandy up-regulated by AA-Na 40 mg/L. Compared with the control group, the mRNA expression of TGF-?1,.CTGF, TIMP-1 and PAI-1 was up-regulated to 1.24,1.31,1.27 and 1.36 times,respectively (P

Objective To study the effects of transcranial magnetic stimulation (TMS) on learning and memory, and angiogenesis and the dendritic structure of hippocampal CA3 pyramidal neurons after cerebral infarction. Methods Forty-eight male Sprague-Dawley rats were divided into a sham operated group, a model group and a TMS group (n = 16). Rat models of focal cerebral infarction were established with unilateral middle cerebral artery (MCA) suture occlusion in the model and TMS groups. The rats of the TMS group were given 4 weeks of TMS treatment beginning 1 day after the infarction (2 times per day, 30 pulses per time). Their learning and memory abilities were tested with a Y-maze. Angiogenesis and the dendritic structure of their hippocampal CA3 pyramidal neurons were detected after 4 weeks. Results Compared with the model group, learning and memory improved significantly in the TMS group. The average microvessel density of the hippocampus in the TMS group was significantly more than in the model group. The total length of apical dendrites of hippocampal CA3 pyramidal neurons in TMS group was significantly longer than in the model group. Conclusions The improved learning and memory observed following TMS treatment are likely to be related to changes in angiogenesis, the dendritic.structure of the hippocampal CA3 pyramidal neurons, and enhanced synaptic plasticity.

Objective: : The facial nerve trace on the ipsilateral side of the vestibular schwannoma was reconstructed by diffusion tensor imaging tractography to identify the adjacent relationship between the facial nerve and the tumor, and to improve the level of intraoperative facial nerve protection. Methods: : The clinical data of 30 cases of unilateral vestibular schwannoma who underwent tumor resection via retrosigmoid approach were collected between January 2019 and December 2020. All cases underwent magnetic resonance imaging examination before operation. Diffusion tensor imaging and anatomical images were used to reconstruct the facial nerve track of the affected side, so as to predict the course of the nerve and its adjacent relationship with the tumor, to compare the actual trace of the facial nerve during operation, verify the degree of coincidence, and evaluate the nerve function (House-Brackmann grade) after surgery. Results: : The facial nerve of 27 out of 30 cases could be displayed by diffusion tensor imaging tractography, and the tracking rate was 90% (27/30). The intraoperative locations of facial nerve shown in 25 cases were consistent with the preoperative reconstruction results. The coincidence rate was 92.6% (25/27). The facial nerves were located on the anterior middle part of the tumor in 14 cases, anterior upper part in eight cases, anterior lower part in seven cases, and superior polar in one case. Intraoperative facial nerve anatomy was preserved in 30 cases. Among the 30 patients, total resection was performed in 28 cases and subtotal resection in two cases. The facial nerve function was evaluated 2 weeks after operation, and the results showed grade I in 12 cases, grade II in 16 cases and grade III in two cases. Conclusion : Preoperative diffusion tensor imaging tractography can clearly show the trajectory and adjacent position of the facial nerve on the side of vestibular schwannoma, which is beneficial to accurately identify and effectively protect the facial nerve during the operation, and is worthy of clinical application and promotion.

Objective:To determine the concentration of hydroxychloroquine (HCQ) and its active metabolite deethylhydroxychloroquine (DHCQ) in breast milk of lactating patients with autoimmune disease. To observe the safety of hydroxychloroquine in lactation period, and to explore the factors that may affect HCQ and DHCQ concentration in the milk.Methods:Lactating patients with autoimmune disease who have taken HCQ for at least 6 months were included in our study. A new high performance liquid chromatography (HPLC) method was established to detect HCQ and DHCQ levels in breast milk. Milk samples were collected at different time points: before taking the drug (0 hours), and 2 hours, 4 hours, 6 hours after taking the drug. In addition, the genotype of cytochrome CYP3A4*1G, CYP3A5*3 and CYP2D6*10 which were related to HCQ metabolism were tested by dideoxy chain termination method. Visual acuity, hearing and growth status of the patients' infants were followed up on a regular basis. T-test, one-way ANOVA and Pearson's test were used for data analysis. Results:In 15 patients, the average concentration of HCQ and DHCQ in the milk of patients taking 200 mg/d were (520±261) ng/ml and (177±112) ng/ml, respectively. While the average concentration of HCQ and DHCQ in the milk of patients taking 400 mg/d were (1 036±374) ng/ml and (397±271) ng/ml, respectively. The peak of HCQ level for 11 patients was at 4 hour after taking the drug, while the others' were at 2 hour. The breast-fed infants did not show any abnormal symptoms of hearing, vision and growth. However, cytochrome gene polymorphism did not affect the peak of HCQ and DHCQ.Conclusion:The concentration of HCQ and DHCQ in breast milk is positively correlated to the dosage. The peak level of HCQ milk is 4 hours after taking the drug. The levels of HCQ and DHCQ at 6 hours are similar as those in the whole blood. It is suggested that patients who take HCQ can feed 4 hours after taking the drug to reduce the HCQ and its active metabolites being absorbed by infants. However, the impact of HCQ on infant safety and gene polymorphism of CYP on milk concentration among individuals needs to be further verified in large sample studies and long-term follow-up.

Objective:To consolidate the current evidences regarding the efficacy of vitamin D supplementation in age-related sarcopenia.Methods:In this systemic review, a comprehensive literature search of scientific research including journal articles and academic dissertations was performed in prominent databases such as PubMed, Web of Science, China National Knowledge Infrastructure (CNKI) and Wanfang Database platforms, spanning from January 31, 2014 to January 31, 2024. Two search protocols integrating keywords and citation tracking were adopted to ensure comprehensiveness of the literature. Using “vitamin D” “ergocalciferols” “cholecalciferol” “sarcopenia” “muscle mass” “muscle strength” “myopenia” “muscle loss” “muscle reduction” “gait speed” “grip strength” “handgrip” as the main key words, focusing on the systematic reviews, meta-analyses of randomized controlled trials (RCT), and individual RCT, the scientific evidence of individual vitamin D intervention on age-related sarcopenia was evaluated and summarized. Research concerning particular disease conditions, children and adolescents, menopausal women, athletes and other specific populations were excluded.Results:A initial search yielded 2 448 articles in Chinese or English. A total of 8 systemic reviews/meta-analysis and 22 individual RCT literatures were included in the final analysis. Although some earlier lower-quality studies reported subtle improvements in skeletal muscle strength with vitamin D supplementation, high-quality systematic reviews/meta-analysis over the past three years had not shown significant positive effects of vitamin D intervention on sarcopenia and its breakdown parameters, such as skeletal muscle mass, muscle strength, and muscle function. Furthermore, the efficiency was influenced to some extent by the participants′ baseline status, such as muscle health and vitamin D nutritional status.Conclusions:Present evidence does not robustly support the efficacy of sole vitamin D supplement on age-related sarcopenia. High-quality clinical trials are imperative to accumulate more robust evidence in the future.

OBJECTIVE：To investigate the ro le of clinical pharmacists in the therapy of fetal tachycardia by oral administration of digoxin through mother. METHODS ：The clinical pharmacists participated in the whole process of drug therapy for a pregnant woman with fetal tachycardia. According to 31+6 weeks of gestation ，the fetal heart rate of 230 beats/min at admission，clinical pharmacists provided the suggestion for the doctor about the safety and blood concentration determination of digoxin in the treatment of fetal tachycardia by mother. The patient ’s blood potassium value was lower than the normal range ，and it was suggested that potassium should be supplemented before digoxin was used ，and the initial dose of digoxin was 0.5 mg per 12 h. On the 7th day in the hospital ，the dosage of digoxin should be adjusted to maintaining dose （0.25 mg per 12 h）；on the 11th day in the hospital ，the patient ’s blood sodium value was low ，and the clinical pharmacists gave diet guidance. At the same time ， the clinical pharmacists explained the adverse reactions of digoxin to the doctors ，nurses and patients ，and closely observed and educated the patients. RESULTS ：Doctors adopted the suggestions of the clinical pharmacists. The fetal heart rate decreased to 180 beats/min from hospital after 13 days of treatment. The maternal digoxin concentration remained stable. No adverse drug reactions occurred in the mother and infant. CONCLUSIONS ：Maternal and child safety should be taken into account in the medication of pregnant patients. The clinical pharmacists assisting doctors to formulate medication strategying ，and carrying out pharmaceutical care for patients ，can ensure the effectiveness and safety of medication for fetal tachycardia.
