Objective:To explore the latent classes of fatigue trajectories and influencing factors in elderly patients with chronic pneumonia.Methods:A convenience sampling method was used to select 188 elderly patients with chronic pneumonia admitted to the Department of Geriatrics at Zhejiang Provincial Tongde Hospital from January 2023 to January 2024. General Data Questionnaires, Nutrition Risk Screening 2002, Athens Insomnia Scale, Hamilton Anxiety Scale, Community Commitment Scale, and Fatigue Scale were used to assess the patients. Patients were followed up for fatigue Scale at the time of consultation (T0) , and at the third (T1) and sixth (T2) months after consultation. Latent class growth analysis was used to model the trajectory of fatigue changes in elderly patients with chronic pneumonia.Results:A total of 188 questionnaires were distributed, with 165 valid responses, yielding an effective response rate of 87.8% (165/188) . The Fatigue Scale scores at T0, T1, and T2 were (4.63±1.74) , (5.54±1.90) , and (7.82±2.84) , respectively. The fatigue trajectories could be classified into three latent classes: low fatigue-slow increase group (74.5%, 123/165) , low fatigue-worsening group (10.3%, 17/165) , and high fatigue-slow increase group (15.2%, 25/165) . Multivariate logistic regression analysis showed that age, smoking index, number of chronic diseases, sleep, anxiety, and duration of cough and sputum were significant influencing factors for the fatigue trajectory in elderly patients with chronic pneumonia ( P<0.05) . Conclusions:Fatigue trajectories in elderly patients with chronic pneumonia exhibit group heterogeneity. Healthcare providers should develop targeted nursing measures based on different trajectory classes to alleviate fatigue and improve quality of life.

Objective To understand and explore the personality characteristic of patients with migraine .To prevent and solve the health problems and provide scientific basis .Methods 100 patients with migraineurs were examined by self -edited question-naier and the Chinese version of the Minnesota Multiphasic Personality Inventory .86 effective questionnaiers which made up by 30 males and 56 females(aged from 18 to 65 ,46 years in average) were collected and analyzed .The subjects were grouped according to the gender ,and compared with the Chinese normal .Results In the male patients ,the measured scales of L ,HS ,D ,Hy ,Pd ,Pt and Ma appeared significantly higher than those in the normal males (P<0 .05) ,while in the female ,the measured scales of F ,Hs ,D , Hy ,Pa ,Pt and Ma appeared significantly higher than those in the normal females (P<0 .05) .Conclusion Patients with migraine have some changes in personality .Male patients and female patients were different .Eealy screening and intervention in the treatment of personality will help to improve the treatment of migraine effect .

Objective To observe the effect of electroacupuncture on the expression of vascular endothelial growth factor receptor-2 (VEGFR-2) mRNA and brain-derived neurotrophic factor (BDNF) protein in brain tissue of rats with focal cerebral ischemia/reperfusion.Methods The focal cerebral ischemia/reperfusion model was established with filament occlusion. 90 rats were randomly divided into control group (n=6), model group (n=42) and electroacupuncture group (n=42). They were observed 2 h, 12 h, 24 h, 3 d, 7 d, 14 d, 21 d after ischemia/reperfusion, 6 rats in each points. Reverse transcription-polymerase chain reaction (RT-PCR) was used to detect the expression of VEGFR-2 mRNA. Immunohistology method was used to detect the expression of BDNF protein. Results The expression of VEGFR-2 mRNA was higher in the electroacupuncture group than in the model group 12 h, 24 h, 3 d after reperfusion (P<0.05). The expression of BDNF protein in the hippocampus increased 2 h (P<0.05), reached peak 24 h (P<0.01) and still higher 3 d (P<0.05) in the electroacupuncture group than in the model group after reperfusion. Conclusion Electroacupuncture can upregulate the expression of VEGFR-2 mRNA and BDNF protein in brain tissue of rats with focal cerebral ischemia/reperfusion. Neuro-angiogenic factor is possibly the molecular basis of coordinated interaction of the nervous and vascular system.

Objective To investigate whether the silicotic process leads to the predominant extrahepatic ceruloplasmin (Cp) gene expression found within the plasma and lung tissue contributing to the significant increase.Methods The previous work of our research group demonstrated changes of ceruloplasmin (Cp) in rat lung tissue and alveolar macrophages during silicosis by electrophoresis analysis, radioimmunological assay and immunoflurescent technique. It is of interest to clarify the cause of elevation of Cp, particularly in the silicotic lung. Though Cp is mainly synthesized in the liver, recent studies have also demonstrated Cp synthesis in rat sertoli cells and human synovial tissue. Wistar male rats (180-220 g) were instilled intratracheally with 50 mg of silica (more than 97% of SiO2 and 95% of the silica particles with diameters less than 5 μm) suspended in 1.0 ml saline. Rats were killed for excising their lung and liver on the 21st day after instillation. Lung cells were harvested by repeated bronchial lavages with saline. Monolayer cells were cultured for 12-16 hours in the serum-free culture medium. Then the alveolar macrophages were collected for assay.Results Dot blotting results showed that Cp mRNA content increased in the liver as expected and was also detectable in the lung, with a nearly 2-fold increase compared with the normal rat lung in the normal group (saline injection). In situ hybrodization and Northern blotting revealed that the lung mesenchymal cells and the alveolar macrophages can express Cp mRNA in silicosis.Conclusions These data indicate that the lung is a prominent site of extrahepatic Cp gene expression during silicosis, thus suggesting that this protein may play a previously unknown role in pulmonary injury or repair.
