RESULTS:The extraction yield order of volatile oil was that F. suspensa heart was higher than F. suspensa,followed by F. suspensa shell and old F. suspensa;there were 18 common peaks in the volatile oil,and the content of β-pinene was the maxi-mum,followed by α-pinene,β-phellandrene,terpinen-4-ol and terpinene;in addition,4-methylene-1-cyclohexanone,3-cyclohex-ene-1-methanol,cumene formaldehyde,1,7-trimethyl-4-methylenedecahydro,palmitic acid,nutmeg aldehyde can only be detected in the volatile oil of old F. suspensa;while α-phellandrene,ocimene,α-terpineol,α-pinocarvone,cis-piperitol,bornyl acetate,α-cubebene and germacrene D can only present in F. suspensa. CONCLUSIONS:The main chemical components in the volatile oil of F. suspensa and old F. suspensa are basically the same,but there are also some differences. The discovery can provide some ba-sis for the material basic research in the pharmacodynamic differences of F. suspensa.

Objective:To investigate the effect of stroke center on the treatment time and short-term prognosis in patients with ultra-early acute cerebral infarction (ACI) within 6 h treated with intravenous thrombolysis.Methods:The clinical data of 113 patients with ultra-early ACI treated with intravenous thrombolysis from July 2017 to July 2019 in Chaoyang City Central Hospital, Liaoning Province were retrospectively analyzed. Among them, 40 patients who received intravenous thrombolysis before the establishment of the stroke center (from July 2017 to July 2018) were enrolled as control group, and 73 patients who received intravenous thrombolysis after the establishment of the stroke center (from August 2018 to July 2019) were as study group. The treatment time nodes were recorded, including the time of onset, time of ACI initial diagnosis, time of completing blood collection and index reporting, time of completing CT examination and diagnosis, time of informed consent and time of onset of intravenous thrombolysis. The short-term prognosis indexes were recorded, including the mortality rate, effective rate of intravenous thrombolysis, improvement rate of neurological deficit at discharge and length of stay.Results:The time of ACI initial diagnosis, time of informed consent and time of onset of intravenous thrombolysis in study group were significantly shorter than those in control group: (5.16 ± 1.97) min vs. (10.23 ± 7.80) min, (36.26 ± 21.89) min vs. (56.23 ± 40.97) min and (85.12 ± 35.46) min vs. (126.28 ± 50.14) min, and there were statistical differences ( P<0.01); there were no statistical difference in the time of onset, time of completing blood collection and index reporting and time of completing CT examination and diagnosis between 2 groups ( P>0.05). The mortality rate in study group was significantly lower than that in control group: 1.4% (1/73) vs. 12.5% (5/40), the effective rate of intravenous thrombolysis and improvement rate of neurological deficit at discharge were significantly higher than those in control group: 84.9% (62/73) vs. 67.5% (27/40) and 76.7% (56/73) vs. 55.0% (22/40), and there were statistical differences ( P<0.05); there was no statistical difference in length of stay between 2 groups ( P>0.05). Conclusions:The establishment of standard stroke center can shorten the treatment time and improve the prognosis of patients with ultra-early ACI.

【Objective】 To retrospectively analyze the epidemiological characteristics and regularity of HIV among voluntary blood donors in our hospital, so as to provide help for the formulation of effective coping strategies for voluntary blood donation, reduce the incidence of blood transmitted diseases, and improve blood safety. 【Methods】 HIV infection and population characteristics of voluntary blood donors in our hospital from January 2010 to December 2019 were statistically analyzed. 【Results】 A total of 330 000 blood donations occurred during 2010 to 2019, and 1 024 HIV-infected blood donors were screened out, with a positive rate of 0.31%. The detection rate was the highest in 2016, with 158 cases infected(158/35 889, 0.44%), followed by 151 in 2015(151/37 586, 0.40%), and 42 in 2010(42/20 824, 0.20%). The difference was statistically significant (χ²=88.754, P<0.001). Among the 1 024 HIV-infected patients, 876 were males and 148 females, with a gender ratio close to 6∶1. The majority were aged between 18~35 years old, accounting for 86.13%. 【Conclusion】 The HIV infection rate among voluntary blood donors had been increasing year by year in recent years. Major blood centers should strengthen the health information before blood donation, carry out HIV screening strictly, select blood donors appropriately, establish a stable blood donation team, so as to reduce the discarding rate of blood.

Objective: To investigate the expression of DNA damage repair factor PDZ binding kinase (PBK) and matrix metalloproteinase 9 (MMP-9) in cervical cancer and the effect on clinical outcomes of concurrent chemoradiotherapy. Methods: A total of 65 cervical cancer pathological specimens were collected from January 2014 to July 2016. Immunohistochemistry was used to detect PBK and MMP-9 expression in the specimens.External irrsdeation was treated with intensity-modulated radiation therapy at a dose of 50 Gy/25 F. After 18 times of external irradiation, high-dose rate postoperative treatment was giver at a dose of 30-36 Gy/5-6 F which lasts 3-4 weeks. Weekly chemotherapy with Cisplatin(DDP) begins simultaneously at the beginning of external irradiation. DDP was administered intravenously at a dosage of 40 mg/m² for 2 to 6 week. All patients were followed-up as routine. The relationship between clinical characteristics and prognosis of patients and the expression of PBK and MMP-9 were analyzed. Results: PBK was expressed in 92.3% of tissues and MMP-9 was expressed in 69.2% of tissues. The expression of PBK was positively associated with overall survival (OS) and disease progression-free survival (PFS) of cervical cancer patients (χ²=4.324, 8.068, P<0.05). The expression of MMP-9 was related with PFS (χ²=5.134, P<0.05). Patients with PBK and MMP-9 expression suffered poor OS and PFS (χ²=5.382, 9.364, P<0.05). Conclusions PBK and MMP-9 could be a biomarker to predict the prognosis of cervical cancer.

Recent studies have discovered a selective autophagy-lipophagy, which can selectively identify and degrade lipids and plays an important role in regulating cellular lipid metabolism and maintaining intracellular lipid homeostasis. The process of lipophagy can be directly or indirectly regulated by genes, enzymes, transcriptional regulators and other factors. This review examines the role of lipophagy in reducing liver lipid content, regulating pancreatic lipid metabolism, and regulating adipose tissue differentiation, and summarizes the findings of the molecules (Rab GTPase, enzymes, ion channels, transcription factors, small molecular substances) involved in the regulation of lipophagy, which points to new directions for the treatment of diseases caused by lipid accumulation.
