  • Diagnostic Efficiency of Pleura Biopsy and Partial Pleura Cryobiopsy viaElectronic Bronchoscope in Exudative Pleural Effusion

    Objective To explore the clinical value of pleura biopsy and partial pleura cryobiopsy via electronic bronchoscope in diagnosis of unknown exudative pleural effusion. Methods Diagnostic results of 563 patients with unknown exudative pleural effusion were analyzed retrospectively. Bronchoscope and routine pleura biopsy were performed in 187 patients. Bronchoscope and routine pleura biopsy plus partial pleura cryobiopsy were performed in 376 patients. Pathological positive rates of the two groups were compared. Results In the 187 patients examined by bronchoscope and routine pleura biopsy from 2006 to 2008, 161 patients obtained pathological positive results ( 86.1% ) . In the 376 patients examined by bronchoscope and routine pleura biopsy plus partial pleura cryobiopsy from 2009 to 2012, 354 patients acquired pathological diagnosis ( 94.1% ) . There was significant difference between the two groups ( P lt; 0.05) . The main complications were bleeding and local chest pain, and they can be controlled easily. Conclusions Electronic bronchoscope and pleura biopsy can obtain high detection rate of nearly 90% in diagnosis of unknown exudative pleural effusion especially when combined with cryobiopsy of partial pleura. Electronic bronchoscope combined with pleura biopsy or cryobiopsy is an alternative in clinical settings when thoracoscope is unavailable.

  • Comparison of open airway inhalation and conventional inhalation in asthma patients

    ObjectiveTo study and compare the effects of inhaled preparations with open airway and conventional inhaled preparation on asthma patients.MethodsThe patients diagnosed with asthma and treated with the same inhaled preparation only who visited the outpatient department of West China Hospital of Sichuan University, were selected as the study subjects from April to September, 2019. The subjects were divided into the test group and the control group according to random ratio 1∶1. The conventional inhaled preparations were used in the control group. The inhaled preparations with open airway were used in the test group. Asthma control, life quality and treatment satisfaction rate were compared between the two groups after 3 months.ResultsA total of 150 subjects were included and one case dropped-off, then 149 effective subjects were obtained in which 75 cases in the test group and 74 cases in the control group. After 3 months’ treatment of inhaled preparations, the proportion of effective asthma control patients in the test group was higher than that in the control group, and the number of patients satisfied with the treatment of inhaled preparations was higher than that in the control group, with statistically significant differences (all P<0.05). The life quality of patients in both groups was improved compared with baseline, and the difference was statistically significant (P<0.05). However, the increase of scores in the test group was more than that in the control group, and the difference was also statistically significant (P<0.05). ConclusionInhaed preparations with open airway is superior to conventional inhaled preparation on asthma patients in asthma control, life quality and treatment satisfaction rate.

  • Effect of emergency fast-track treatment on dangerous upper gastrointestinal bleeding

    Objective To investigate the effect of emergency fast-track treatment on dangerous upper gastrointestinal bleeding. Methods Seventy-six patients who received traditional treatment between October 2020 and March 2021 were included in the traditional treatment group, and 82 patients who entered the emergency fast track for dangerous upper gastrointestinal bleeding between April 2021 and September 2021 were included in the fast-track treatment group. The patients in the traditional treatment group were treated with the traditional single-subject diagnosis and treatment mode, and the patients in the fast-track treatment group were treated according to the multidisciplinary diagnosis and treatment procedures of emergency fast track for dangerous upper gastrointestinal bleeding. The length of emergency stay, 24-hour endoscopic completion rate, effective rate, and length of hospital stay were compared between the two groups. Results The length of emergency stay [(3.75±3.19) vs. (6.51±4.72) h], the effective rate (96.3% vs. 85.5%) and the length of hospital stay [(8.26±2.51) vs. (11.07±2.79) d] were significantly better in the fast-track group than those in the traditional treatment group (P<0.05). There was no significant difference in the 24-hour endoscopic completion rate between the two groups (96.3% vs. 96.1%, P>0.05). Conclusion Compared with the traditional treatment mode, the fast-track treatment mode can significantly improve the treatment efficiency, and reduce the lengths of emergency stay and hospital stay.

  • Study on Significance and Expression of Transforming Growth Factor α and β1 after 90% Portal Vein Ligation in Rats

    Objective To investigate the expressions of transforming growth factor (TGF) -α and -β1 after 90% portal branch ligation (PBL) in rats. Methods Ninety-six SD rats were randomly divided into sham operation group and portal vein branches ligation group. The weight of both ligated and unligated lobes of liver were measured on 0.5, 1, 3, 5, 7, 14, 21, and 28 d after operation. The morphological changes of the unligated liver lobes were observed by microscope. The expressions of proliferating cell nuclear antigen (PCNA), TGF-α, and TGF-β1 of the unligated liver lobes were detected by immunohistochemistry. Results After the ligation of 90% portal vein branches, hepatic lobe at the ligated side diminished progressively after ligation, whereas the lobes of the unligated side underwent compensatory regeneration. The ratio of unligated lobes weight to the whole liver increased slowly within 1 d, speeded up significantly during 1-5 d period, increased slowly on 5 d, and reached plateau phase on 7 d after operation. The expressions of PCNA protein markedly increased within 0.5-3 d (Plt;0.01), which reached the peak on 5 d and decreased slightly on 7 d after operation, but still higher than sham operation group level, and then gradually returned to the level of sham operation group lately. The expressions of TGF-α and TGF-β1 in the unligated liver lobes markedly increased on 0.5 d, and reached the peak on 3 d and 1 d respectively, and then gradually returned to the level of sham operation group in 7-28 d after operation. Conclusion Ligation of 90% portal branches can induce active regeneration of unligated liver lobes in rats, whose initiation and proliferation are involved in the expressions of TGF-α and TGF-β1 protein.
