Objective To explore the effect of respiratory training based on mechanical vibration-assisted sputum expulsion on arterial blood gases in patients with chronic obstructive pulmonary type 2 respiratory failure and clinical efficacy observation. Methods 105 patients with chronic obstructive pulmonary disease combined with type 2 respiratory failure who were hospitalized in our hospital from November 2019 to February 2023 were selected as study subjects. They were randomly numbered and divided into experimental and control groups according to the order of admission, and 3 patients withdrew from the study cohort due to their own reasons, and 51 cases each of the experimental and control groups were finally included. Patients in the control group were given conventional treatment and lung function exercise, while the experimental group was given respiratory training with mechanical vibration-assisted sputum expulsion. Lung function and blood gas analysis indexes were measured before and 2 weeks after treatment to evaluate the clinical efficacy and incidence of adverse events in the two groups. Results After the treatment, pulmonary function indexes such as PEF, FVC, FEV1 and FEV1/FVC, and blood gas analysis indexes such as PaO2, PaCO2 of the experimental group and daily sputum excretion improved significantly compared with those of the pre-treatment and control groups (P<0.05). The total clinical efficacy rate of the patients in the experimental group was significantly higher than that of the control group (P<0.05), and the incidence of adverse events was lower than that of the control group, but the difference was not statistically significant (P>0.05). Conclusion Respiratory training based on mechanical vibration-assisted sputum expectoration can help improve the lung function and blood gas level of patients with chronic obstructive pulmonary disease combined with type 2 respiratory failure, and it has a certain clinical value in promoting the rehabilitation and prognosis of patients.
Objective To introduce an effective method of treating old scaphoid fracture. Methods From April 1995 to April2002,11 patients with old scaphoid fracture were treated with transposition of vascularized periosteal flap and internal fixation; if necessary, the radial styloid was removed. Out of 11 patients( 8 males and 3 females, aged from 17 to 46 years), the fracture siteswere medialscaphoid in 7, the proximal one in 2 and the distal one in 2. The X-ray filmsshowed separated fracture lines. The fracture lines were less than 1 mm in 4patients and more than 1 mm in 3 patients. Sclerosis of skeleton ends and cystoid degeneration occurred in 2 patients, respectively. Results After a follow-up of 3 to 24 months, the fracture healing was obtained within 4 months in 9 casesand within 6 to 7 months in 2 cases. Internal fixation was taken out 3 months after bone healing. The carpal joint pain and weakness vanished in all cases.Conclusion Transposition of vascularized periosteal flap and internal fixation have many advantages, such as easy dissection, rich blood supply, quick new bone formation, short time of fracture healing and satisfactory function recovery of carpal joint.
Objective To compare the clinical effect of tissue selecting therapy stapler (TST) and procedure for prolapse and hemorrhoids (PPH) in treatment of hemorrhoid in Ⅲ-Ⅳ degree. Methods Clinical data of 80 cases of hemorrhoid in Ⅲ-Ⅳ degree who treated in The First Affiliated Hospital of Harbin Medical University from May 2015 to July 2015 were retrospectively collected. All the 80 cases were divided into TST group (n=40) and PPH group (n=40) according to the surgical types. The comparison of the clinical effect of 2 groups was performed. Results The operative time, hospital stay, intraoperative blood loss, anal fall bilge feeling score, postoperative pain score at 3 time points, and the incidence of anal secretions of TST group were lower or shorter than those corresponding indexes of PPH group (P<0.05). But there was no significant difference in cure rate, the incidence of urinary retention, the incidence of anal stenosis, the incidence of intractable pain, and satisfaction situation between the 2 groups (P>0.05). All of the cases were followed up for 3 months, during the follow-up period, no one suffered from rectal vaginal fistula, fecal incontinence, and recurrence. Conclusion TST and PPH both have satisfactory effect in treatment of hemorrhoid in Ⅲ-Ⅳ degree, but TST has advan- tages of less blood loss, shorter operative time, rapid postoperative recovery, and less pain.
Objective To summarize the new progress of circulating tumor cell markers and their clinical application. Methods The related literatures about the detection and clinical application of circulating tumor cell markers in recent years were reviewed. Resuts Epithelial markers, other markers such as human epidermal growth factor receptor 2 (HER2), estrogen receptor (ER), and immuno-checkpoint genes have also become a useful means to detect the ability of malignant metastasis of circulating tumor cells (CTCs). Moreover, the epithelial-to-mesenchymal transition (EMT) and cancer stem cells (CSCs) have also received increasing attention as important CTCs markers owing to their roles in the biological progression of metastasis. Conclusions Through the detection of peripheral blood CTCs, to identify early cancer, monitoring the metastasis and recurrence of cancer and its treatment on all has the very good guiding significance. Signs of circulating tumor cells has great clinical application value in diagnosis and treatment of tumor and prognosis.
Objective To systematically evaluate the efficacy and safety of palonosetron hydrochloride injection for the prevention of chemotherapy-induced nausea and vomiting (CINV) associated with moderately or highly emetogenic chemotherapy. Methods Searched PubMed, Embase, Web of Science, Cochrane Library, Chinese National Knowledge Infrastructure, Chinese Biological Medical Database, Wanfang Database and VIP Chinese Science and Technology Journal Database to find domestic and abroad published literatures of palonosetron used to control CINV associated with moderately or highly emetogenic chemotherapy. Two reviewers independently selected literatures, extracted data and assessed quality of the included studies by the Cochrane handbook 5.1. Meta-analysis was performed using RevMan 5.3 software. Results Twenty trials involving 4 919 patients were included. The results of meta-analysis showed statistically significant differences between palonosetron and first-generation 5-hydroxytryptamine3 receptor antagonists (5-HT3RAS) in prevention of acute〔RR=1.09, 95%CI (1.40, 1.14),P=0.000 4〕, delayed 〔RR=1.26, 95%CI (1.15, 1.37),P＜0.000 01〕, and overall phase of CINV 〔RR=1.19, 95%CI (1.10, 1.30),P＜0.000 1〕. Subgroup analyses indicated that there were no statistical significances between palonosetron and granisetron (P=0.09) or ondansetron (P=0.08) in prevention of acute CINV, as well as between palonosetron and first-generation 5-HT3RAS in prophylaxis of moderately CINV (P=0.18), while there was statistical significance in favor of palonosetron in prophylaxis of delayed and overall phase of CINV. Compared with first-generation 5-HT3RAS, there were different in prophylaxis of highly chemotherapy-induced acute〔RR=1.10, 95%CI (1.02, 1.18),P=0.01〕, delayed〔RR=1.20, 95%CI (1.06, 1.36),P=0.005〕, and overall phase〔RR=1.18, 95%CI (1.04,1.33),P=0.008〕of CINV. In terms of safety, such as headache, constipation, diarrhea and dizziness, there were no statistical differences between two groups. Conclusions Palonosetron hydrochloride injection showed efficacy in prophylaxis of moderately or highly CINV, and didn't increase adverse events. Palonosetron hydrochloride injection is more better than first-generation 5-HT3RAS, especially in prevention of highly CINV, and can significantly improve the control rate of acute, delayed, and overall phase of CINV.
