Objective To investigate the impact of laparoscopic versus. open hepatic resection for liver cancer on clinical rehabilitation and humoral immune function in patients organism. Methods Forty-four patients of laparoscopic and open left-lateral sectionectomy from January 2010 to June 2012 were selected， including 22 patients of laparoscopy group and 22 patients of conventional laparotomy group. The levels of IgG， IgA， IgM， C3， C4， C reactive protein （CRP）， IL-2， IL-6， and TNF-α in peripheral blood of patients on the last day before operation， first day and 5th day after operation were determinated by using ELISA assay. At the same time， the operative time， intraoperative bleeding， hospitalization time， and complications after operation between two groups were compared. Results The postoperative analgesic using time， first time eating， and hospitalization time in laparoscopic group were （1.9±0.8） days， （2.2±0.5） days， and （6.3±1.3） days， respectively， they were shorter than that in conventional laparotomy group （P＜0.05）. The operative time， intraoperative bleeding， complication rate， and mortality in two groups were not significant differences（P＞0.05） . Compared with before operation， the levels of C3， C4， IgA， IgG， IgM， and IL-2 on the first day after oper-ation in two groups were obviusly reduced， the levels of CRP， IL-6， and TNF-α on the first day after operation in two groups were significantly increased. The levels of C3， C4， lgA， IgG， lgM， and IL-2 on the first day after operation in conventional laparotomy group were significantly decreased than that in laparoscopic group （P＜0.05）. On the 5th day after operation， the levels of C3， C4， lgA， IgG， lgM， and IL-2 of laparoscopy group increased， the levels of CRP， IL-6，and TNF-α were reduced，that were no difference compared with before operation. Compared with before operation，the levels of C3， C4， lgA， IgG， lgM， and IL-2 of conventional laparotomy group were still at a low level state， and the levels of CRP， IL-6， and TNF-α were still at a high level state on the 5th day after operation. Conclusions Laparoscopic resection of liver cancer after operation， the patients’ recovery are quickly， and the impact on humoral immune function of laparoscopic radical resection for liver cancer patients is significantly less than that conventional laparotomy.
Idiopathic thrombocytopenic purpura (ITP) is a common bloody disease with a high incidence in children, but its diagnostic method is exclusive diagnosis, and the existing detection techniques are mostly invasive, which may cause secondary injury to patients and also may increase the risk of disease. In order to make up for the lack of the detection method, this study made a preliminary exploration on the diagnosis of children's ITP from the perspective of infrared thermography. In this study, a total of 11 healthy children and 22 ITP children's frontal infrared thermal images were collected, and the pattern characteristic (PFD), average temperature (Troi) and maximum temperature (MAX) characteristics of 7 target areas were extracted. The weighted PFD parameters were correlated with the platelet count commonly used in clinical diagnosis, and the sensitivity and specificity of the weighted PFD parameters for children's ITP were calculated through the receiver operating characteristic curve (ROC). The final results showed that the difference of the weighted PFD parameters between healthy children and ITP children was statistically significant, and the parameters negatively correlated with platelet count. Under the ROC curve, the area under the curve (AUC) of this parameter is as high as 92.1%. Based on the research results of this paper, infrared thermography can clearly show the difference between ITP children and healthy children. It is hoped that the methods proposed in this paper can non-invasively and objectively describe the characteristics of ITP infrared thermal imaging of children, and provide a new ideas for ITP diagnosis.
Objective To evaluate whether respiratory training can improve motor function, exercise endurance, and activity of daily living (ADL) in stroke patients. Methods The randomized controlled trials of the effects of respiratory training on motor function, exercise endurance, and ADL in stroke patients were searched in PubMed, Embase, Google Scholar, China National Knowledge Infrastructure, Wanfang, and VIP Database. The search date was from the establishment of each database to December 2018. The control group received routine rehabilitation, medical treatment or other interventions, and the trial group added respiratory training on that basis. Outcome measures included the Fugl-Meyer Assessment (FMA), the 6-minute walk test (6MWT), and the modified Barthel Index (BI). The literature was independently screened by two investigators according to the inclusion and exclusion criteria, and the quality of the included articles was evaluated using the Physiotherapy Evidence Database scale and Cochrane Library systematic review criteria. Statistical analysis was performed using RevMan 5.3 software. Results A total of 11 articles with 741 stroke patients were included. Meta-analysis showed that in the trial group the exercise endurance [mean difference (MD)=41.50 m, 95% confidence interval (CI) (7.63, 75.37) m, P=0.02], ADL [MD=9.97, 95%CI (3.99, 15.96), P=0.001], and motor function [MD=8.00, 95%CI (1.29, 14.70), P=0.02] were improved compared with those in the control group. Subgroup analysis showed that after 8-10 weeks of intervention, BI of the trial group was higher than that of the control group [MD=25.37, 95%CI (16.49, 34.25), P<0.000 01]; after 8 weeks and 12 weeks to 3 months of intervention, FMA of the trial group was higher than that of the control group [ after 8 weeks: MD=20.40, 95%CI (9.72, 31.08), P=0.000 2; after 12 weeks to 3 months: MD=6.18, 95%CI (3.57, 8.79), P<0.000 01]. Conclusions The results of this study showed that respiratory training can improve exercise tolerance, ADL, and motor function in stroke patients. In consideration of the limited number of included articles as well as the heterogeneity among included articles in the current study, and the lack of long-term follow-up period, further studies could use more optimized respiratory training programs to conduct high-quality researches with bigger sample sizes.
Reduced chemotactic migration of polymorphonuclear neutrophil (PMN) in sepsis patients leads to decreased bacterial clearance and accelerates the progression of sepsis disease. Quantification of PMN chemotaxis in sepsis patients can help characterize the immune health of sepsis patients. Microfluidic microarrays have been widely used for cell chemotaxis analysis because of the advantages of low reagent consumption, near-physiological environment, and visualization of the migration process. Currently, the study of PMN chemotaxis using microfluidic chips is mainly limited by the cumbersome cell separation operation and low throughput of microfluidic chips. In this paper, we first designed an inertial cell sorting chip to achieve label-free separation of the two major cell types by using the basic principle that leukocytes (mainly granulocytes, lymphocytes and monocytes) and erythrocytes move to different positions of the spiral microchannel when they move in the spiral microchannel under different strength of inertial force and Dean's resistance. Subsequently, in this paper, we designed a multi-channel cell migration chip and constructed a microfluidic PMN inertial label-free sorting and chemotaxis analysis platform. The inertial cell sorting chip separates leukocyte populations and then injects them into the multi-channel cell migration chip, which can complete the chemotaxis test of PMN to chemotactic peptide (fMLP) within 15 min. The remaining cells, such as monocytes with slow motility and lymphocytes that require pre-activation with proliferative culture, do not undergo significant chemotactic migration. The test results of sepsis patients (n=6) and healthy volunteers (n=3) recruited in this study showed that the chemotaxis index (CI) and migration velocity (v) of PMN from sepsis patients were significantly weaker than those from healthy volunteers. In conclusion, the microfluidic PMN inertial label-free sorting and chemotaxis analysis platform constructed in this paper can be used as a new tool for cell label-free sorting and migration studies.
ObjectiveTo investigate the clinical efficacy of multidisciplinary team (MDT) model combined with Da Vinci robot-assisted thoracic surgery in the treatment of early non-small cell lung cancer (NSCLC). MethodsFrom July 2020 to December 2021, the patients with NSCLC who received Da Vinci robot-assisted thoracic surgery in the Department of Thoracic Surgery, General Hospital of Northern Theater Command were collected. According to whether MDT were performed before hospitalization, the patients were divided into an MDT group and a common group. The recovery and clinical efficacy were compared between the two groups. ResultsA total of 187 patients were enrolled, including 81 males and 106 females, aged 63 (56, 67) years. There were 85 patients in the MDT group, and 102 patients in the common group. Compared with the common group, the MDT group had lower incidence of postoperative complications (9.4% vs. 29.4%, P=0.017), shorter intraoperative operation time [55 (45, 61) min vs. 79 (65, 90) min, P<0.001], and less intraoperative blood loss [25 (20, 30) mL vs. 30 (20, 50) mL, P=0.029] in the same operation mode. In addition, the drainage volume on the second postoperative day [270 (200, 350) mL vs. 215 (190, 300) mL, P=0.004], the number of dissected lymph nodes groups [6 (5, 6) groups vs. 5 (3, 6) groups, P=0.004] and the number of dissected lymph nodes [16 (13, 21) vs. 13 (9, 20), P=0.005] in the MDT group were significantly better than those in the common group. The differences in the postoperative intubation time and postoperative hospital stay between the two groups were not statistically significant (P>0.05). ConclusionMDT combined with Da Vinci robot-assisted thoracic surgery can further reduce the risk of surgery, improve the clinical treatment effect, reduce the incidence of postoperative complications, and accelerate the rehabilitation of patients.
Objective To investigate the early effectiveness of the limited unique coracoid osteotomy suture button fixation Latarjet (LU-tarjet)-congruent-arc (CA) technique (LU-tarjet-CA) in treating recurrent shoulder dislocations with huge glenoid defect. Methods The clinical data of 12 patients with recurrent shoulder dislocation and huge glenoid defect who met the selection criteria and treated with arthroscopic LU-tarjet-CA between January 2021 and December 2023 were retrospectively analyzed. The cohort included 8 males and 4 females, aged 20-40 years with an average age of 30.4 years. The range of glenoid bone loss was 30%-40%, with an average of 35.5%. The time from symptom onset to hospital admission ranged from 1 to 36 months, with an average of 18.5 months. The University of California Los Angeles (UCLA) score, American Association for Shoulder and Elbow Surgery (ASES) score, Walch-Duplay score, and Rowe score were used to evaluate shoulder function preoperatively and at 3, 6, and 12 months postoperatively. CT three-dimensional (3D) reconstruction was used to assess coracoid healing and plasticity at 3, 6, and 12 months postoperatively. Subjective satisfaction of patient was recorded at last follow-up. Results All incisions healed by first intention, with no incision infection or nerve injury. All 12 patients were followed up 12 months. One patient developed Propionibacterium acnes infection within the joint postoperatively and recovered after initial arthroscopic debridement and anti-inflammatory treatment. At 3 months after operation, CT 3D-reconstruction showed 1 case of complete coracoid absorption; neither of these two patients experienced redislocation. The remaining patients exhibited partial coracoid absorption but displayed local reshaping, filling the preoperative defect area, and bony fusion between the coracoid and the glenoid. At last follow-up, 9 patients (75%) were very satisfied with the outcome, and 3 patients (25%) were satisfied; the satisfied patients experienced postoperative shoulder stiffness caused by suboptimal functional exercise but did not have impaired daily life activities. The UCLA score, ASES score, Walch-Duplay score, and Rowe score at 3, 6, and 12 months postoperatively were significantly better than preoperative scores, and each score improved further over time postoperatively, with significant differences between different time points (P<0.05). Conclusion The arthroscopic LU-tarjet-CA technique for treating recurrent shoulder dislocations with huge glenoid defect can achieve the surgical objective of bony blockade and filling bone defects to prevent shoulder dislocation, thereby improving patients’ quality of life and shoulder joint function and stability.
Objective To investigate the effect of common iliac vein allograft replacing the portal vein-superior mesenteric vein transition area invaded by pancreatic cancer. Methods The clinical data of a patient with pancreatic cancer admitted to the Beijing Tsinghua Changgung Hospital in December 2021 who underwent pancreaticoduodenectomy combined with common iliac vein allograft replacing the junction of portal vein, superior mesenteric vein and splenic vein were analyzed retrospectively. The patient was a 77-year-old man who complained of “epigastric pain for 1 month and pancreatic mass was found for 1 week”. After admission, the patient was diagnosed with pancreatic cancer through inspection, and then the surgery was required. Preoperative examination and intraoperative exploration confirmed that the junction of portal vein, superior mesenteric vein, and spleen vein was invaded by tumor. In addition, the length of the invaded vessels measured by preoperative 3D reconstruction image was 5.5 cm, and the distance between the broken end of portal vein and the broken end of superior mesenteric vein measured was 4.5 cm during the operation. After tumor and vessels were resected, vascular anastomosis could not be performed directly. After accurate evaluation, pancreaticoduodenectomy combined with common iliac vein allograft replacing the junction of portal vein, superior mesenteric vein and splenic vein was performed. The operative time was 11 h, and the intraoperative blood loss was 400 mL. After the operation, the routine treatment was performed in ICU and was transferred to the general ward on the 7th day. Postoperative laboratory tests were performed to monitor liver function changes routinely, and imaging examination were was performed to monitor portal venous system blood flow. Results Postoperative complications such as biliary fistula, pancreatic fistula, hemorrhage, infection and thrombosis were not occurred. Postoperative pathological diagnosis: pancreatic ductal adenocarcinoma, medium-low differentiation. Enhanced CT reexamination on the 2nd and 13th day after the operation showed that the blood flow at the junction of portal vein, superior mesenteric vein and splenic vein of the common iliac vein allograft was unobstructed, and there was no stenosis or thrombosis at each anastomosis. Conclusions The application of common iliac vein allograft replacing the portal vein-superior mesenteric vein transition area invaded by pancreatic cancer is safe and feasible. The short-term efficacy is satisfactory, and long-term prognosis remains to be further observed.
