Evidence suggests that the nociceptive flexion reflex threshold may not be different between patients with fibromyalgia and healthy controls. A unified and rigorous methodology and sample size calculation (probably sex specific investigation) is required for the assessment of nociceptive flexion reflex threshold in patients with fibromyalgia.

The present study aims to evaluate the comparability of the results of two methodologies for detecting human chorionic gonadotropin (HCG) to assess whether the immunofluorescence method for detecting HCG is adequate for clinical applications.
Referring to the protocol requirements of the American Clinical Laboratory Standards Institute (CLSI) EP9-A2 (methodological matching and bias assessment with patient samples), we collected 40 fresh serum specimens from our outpatients and inpatients, including 20 specimens with abnormal HCG concentrations (eight samples with different concentration ranges were selected daily and HCG was measured simultaneously with the two testing systems for five consecutive days). The assays were performed on a Dxl 800 fully automated immunoassay analyzer from Beckman Coulter Inc., USA, as a comparative method and on a Jet-iStar 3000 immunoassay analyzer from Zhonghan Shengtai Inc. as an experimental method. Methodological comparison and bias assessment of the results of the two methods for HCG detection were performed. The OLR regression model was used for calculating bias and regression analysis, and Spearman's rank correlation coefficient was used for correlation analysis. The correlation and comparability of the two systems were calculated based on the results of the analysis.
A good correlation in HCG results in the range of 5-50,000 U/mL was obtained from the two assay systems (r = 0.998) with the regression equation of y = 1.020x + 12.96. The estimated deviation was within the permissible deviation and acceptable.
The results of HCG measurement by the two different assay systems were well correlated and comparable.

To explore the value of medical three-dimensional visualization technology in precise preoperative assessment of complex abdominal wall defects.
The clinical data of 30 patients were analyzed retrospectively from November 2017 to December 2020 in our department. Ten patients had abdominal wall hernias and 20 patients suffered from abdominal wall tumors. CT examination was performed, and data were stored in the form of DICOM. Three-dimensional reconstruction and related data analysis were performed by Medraw software, which can accurately show the calculation of the abdominal wall defect area, abdominal wall defect classification and zoning.
The ratio of the volume of the hernia sac to the whole abdominal volume in 10 patients with abdominal wall hernia was 4.75%. The average ratio of defect area to the whole abdominal wall in 16 patients suffered from abdominal wall tumors was 17.68%. CPI-1205 Preoperative three-dimensional reconstruction can accurately obtain an average abdominal wall defect area of 227.83 ± 157.33 cm
and accurate abdominal wall classification and zoning. Combined with clinical information, we can develop personalized surgical plans for patients. The average operating time was 5.39 ± 2.71 h, respectively, and the average hospital stay was 22.77 ± 11.59 days. The mean follow-up time was 21.09 ± 9.72 months. The incidence of postoperative complications was 23.33% (7/30). The recurrence rates of incisional hernias and abdominal wall tumors were 20.00% (2/10) and 15.00% (3/20), respectively. The patient survival rate was 86.67% (26/30).
Three-dimensional visualization technology can be used for the accurate evaluation of patients with complex abdominal defects before surgery and can help surgeons design personalized surgical plans for patients.

To compare the therapeutic effect of the quadrant channel and delta large channel techniques in lumbar degenerative diseases.
According to the inclusion criteria, 62 patients suffering from lumbar degenerative disease were selected for the present study, which was conducted from September 2018 to June 2020. Patients were divided into Group A (quadrant channel technology) and Group B (delta large channel technology), which comprised 28 and 34 patients, respectively. The factors compared between the two groups were operation time, length of incision, blood loss, ambulation time, length of hospitalization, visual analogue scale (VAS) preoperatively, 7 days postoperatively, and 30 days postoperatively, and Oswestry dysfunction score (ODI).
The length of incision, blood loss, ambulation time, and length of hospitalization stay in Group A were significantly higher compared with Group B (P < 0.05). There was no significant difference between the two groups in operation time, preoperative ODI index, preoperative VAS scores, and thirty-day postoperative VAS scores (P > 0.05). The seven-day postoperative VAS score, seven-day postoperative ODI index, and thirty-day postoperative ODI index of Group A were significantly higher than those of Group B (P < 0.05). The preoperative VAS score and ODI index in both groups were significantly higher compared with after operation (P < 0.05).
Both surgical methods achieved a good clinical outcome in the treatment of lumbar degenerative diseases. The delta large channel technique may offer some advantages over quadrant channel technology, such as less trauma and bleeding and faster recovery time.
