Objective To observe the correlations of chest CT quantitative parameters in patients with acute exacerbation of chronic obstructive pulmonary disease(AECOPD)with blood eosinophil(EOS)level.Methods Chest CT data of 162 AECOPD patients with elevated eosinophils were retrospectively analyzed.The patients were divided into low EOS group(n=105)and high EOS group(n=57)according to the absolute counting of blood EOS.The quantitative CT parameters,including the number of whole lung bronchi and the volume of blood vessels,low-attenuation area percentage(LAA％)of whole lung,of left/right lung and each lobe of lung,as well as the luminal diameter(LD),wall thickness(WT),wall area(WA)and WA percentage of total bronchial cross-section(WA％)of grade 3 to 8 bronchi were compared between groups.Spearman correlations were performed to analyze the correlations of quantitative CT parameters with blood EOS level.Results LAA％of the whole lung,of the left/right lung and each lobe of lung,as well as of the upper lobe of right lung LDgrade4,middle lobe of right lung WTgrade5,upper lobe of right lung WAgrade4,middle lobe of right lung WAgrade5 and lower lobe of left lung WAgrade3 in low EOS group were all higher than those in high EOS group(all P＜0.05).Except for the upper lobe of right lung LDgrade4,the above quantitative CT indexes being significant different between groups were all weakly and negatively correlated with blood EOS level(r=-0.335 to-0.164,all P＜0.05).Conclusion Chest CT quantitative parameters of AECOPD patients were correlated with blood EOS level,among which LAA％,a part of WT and WA were all weakly negatively correlated with blood EOS level.

Objective:To establish a nomogram prediction model for recurrence within 2 years after radical resection of hepatocellular carcinoma (HCC) based on clinical and ultrasonographic characteristics.Methods:Clinical data from 405 HCC patients (including 327 males and 78 females), aged 60 (53, 66) years old, who underwent radical hepatectomy in the Zhongshan Hospital, Fudan University, from January to December 2021, were retrospectively collected. The patients were divided into two groups: the training group ( n=283) and the validation group ( n=122). Based on recurrence within 2 years after surgery, the 283 patients in the training group were further categorized into the recurrence group ( n=73) and the non-recurrence group ( n=210). Among the 122 patients in the validation group, 33 had recurrence within 2 years, while 89 did not. Data on age, microvascular invasion, alpha-fetoprotein (AFP), AFP lentil lectin-reactive fraction (AFP-L3), protein induced by vitamin K absence or antagonist-II (PIVKA-II), tumor number, and enhancement homogeneity were collected. Logistic regression analysis was performed on the training group to identify risk factors associated with postoperative recurrence, and a nomogram model for predicting HCC recurrence was constructed based on these factors. Calibration curves were used to compare the consistency between predicted and actual outcomes in both the training and validation groups. Results:Multivariate logistic regression analysis revealed that younger age ( OR=0.976, 95% CI: 0.953-1.000, P=0.004), higher AFP-L3 ( OR=1.066, 95% CI: 1.014-1.120, P=0.012), higher PIVKA-II ( OR=1.000, 95% CI: 1.000-1.001, P=0.042), multiple tumors ( OR=0.399, 95% CI: 0.225-0.706, P=0.038), and heterogeneous enhancement ( OR=0.472, 95% CI: 0.243-0.916, P=0.045) were significant risk factors for recurrence after partial hepatectomy in HCC patients. The nomogram constructed based on these variables had a C-index of 0.87 (95% CI: 0.81-0.93) in the training group and 0.83 (95% CI: 0.77-0.89) in the validation group. The calibration curves for predicting recurrence within 2 years after partial hepatectomy in HCC patients showed a high degree of fit in both the training and validation groups, indicating a good agreement between predicted and actual outcomes. Conclusion:The nomogram model constructed based on preoperative clinical and ultrasonographic characteristics can effectively predict the risk of recurrence within 2 years after radical resection of HCC.

Objective:To investigate the effect and of piperine(PIP)on nerve injury in rats with cerebral infarction.Meth-ods:The rat model of cerebral infarction was prepared by modified thread embolism method.The rats were divided into Sham group,Model group,piperine group(PIP group,20 mg/kg piperine),piperine+PKA inhibitor group(PIP+H-89 group,20 mg/kg PIP+5 mg/kg H-89).The rats were scored for neurological impairment,the volume of cerebral infarction,neuronal damage and neuronal apoptosis were observed,and the levels of cAMP,IL-1β and IL-6 in hippocampus and the protein expressions of GFAP,NSE,AC6,PKA,p-CREB,CREB and BDNF were detected.Results:Compared with Sham group,Model group had large cerebral infarction,cerebral in-farction volume,the neurological deficit score,neuronal apoptosis rate,the levels of IL-6 and IL-1β in hippocampus,and number of GFAP positive cells,the positive expression rates of NSE protein increased,the number of Nissl bodies,and the expressions of cAMP,AC6,PKA,p-CREB and BDNF proteins in hippocampus decreased(P<0.05);compared with Model group,cerebral infarc-tion volume,the neurological deficit score,neuronal apoptosis rate,the levels of IL-6 and IL-1β in hippocampus,and number of GFAP positive cells,the positive expression rates of NSE protein in the PIP group decreased,the number of Nissl bodies,and the ex-pressions of cAMP,AC6,PKA,p-CREB and BDNF proteins in hippocampus increased(P<0.05);the effect of piperine in improving nerve injury in rats with cerebral infarction was able to be reversed by H-89.Conclusion:PIP can inhibit the apoptosis of hippocampal neurons,and improve the neural injury induced by cerebral infarction by activating AC/PKA/CREB signal pathway.

Acupuncture can improve the motor and non-motor symptoms of Parkinson's disease, and the effect of acupuncture combined with drug therapy is better than that of drug therapy alone. The possible mechanism includes inhibiting α-synuclein aggregation, oxidative stress, and neuroinflammation, inhibiting the apoptosis of dopaminergic neurons, and achieving a neuroprotective effect. The points mainly selected for Acupuncture treatment for this disease are Zusanli (ST 36), Yanglingquan (GB 34), Taichong (LR 3), Xuehai (SP 10), and other points. Early use of acupuncture and acupuncture combined with medical treatment strategy is worthy of clinical application.

Objective:To explore the effects of information drug close-loop management mode on adverse events of nursing medication and to analyze the 46 cases of adverse events after implementing the information drug close-loop management mode so as to understand the event characteristics and formulate the countermeasures with the aim to reduce the nursing medication errors.Methods:We retrospectively analyzed the 46 cases of adverse events of nursing medication reported by system in the First Affiliated Hospital of Xiamen University after implementing the information drug close-loop management mode (from January to December 2018) . Among the 46 cases of events, we analyzed the classifications, causes and links of error and compared those events with adverse events of nursing medication before implementing the information drug close-loop management mode in 2017.Results:After carrying out the drug close-loop management, the adverse events of medication declined compared with that in 2017, but there was no statistical difference ( P>0.05) . The adverse events included 17 (17/46, 36.96%) errors in identification, 8 (8/46, 17.39%) medication omissions, 7 (7/46, 15.22%) errors in dose and 5 (5/46, 10.87%) errors in route. The links of medication errors were mainly in drug dispensing (26 cases) and arranging (14 cases) . Conclusions:Adverse events of medication most often occur in drug dispensing. The most common errors were misidentification. Nursing managers should formulate the preventive intervention based on the classifications and characteristics of adverse events in nursing medication administering, and monitor as well as improve the rate of sweeping code in drug close-loop, strength training for nurses, and check the drug dispensing and arranging well.
