OBJECTIVE: To explore the pain-location interaction between pressure-sensitive points on the body surface and traditional acupoints in patients with chronic non-specific low back pain (CNLBP) under different disease courses, using Euclidean distance and multivariate statistical analysis. METHODS: A pressure-sensitive point detection was performed on 30 CNLBP patients with varying disease courses. A constant pressure was applied using an FDK20 algometer within a designated lumbar area, a total of 50 points were tested, and the tested points were numbered; the visual analogue scale (VAS) pain score was recorded simultaneously. MatlabR2022a9.12. software was used to extract the positions of pressure-sensitive points, and preprocessing and normalization of point location and VAS scores data were conducted. Under constraint conditions (VAS≥8.0 ∩ Euclidean distance to acupoint≤0.5), the proportion of pressure-sensitive points within the Euclidean distance threshold to each acupoint (PVD_acupoint) was calculated, followed by multivariate statistical analysis. RESULTS: ①Constrained analysis of PVD_acupoint showed that PVD_{Qihaishu (BL24)} and PVD_{Dachangshu (BL25)} were positively correlated with disease course (r=0.55, P<0.01). ②Factor analysis and silhouette analysis revealed that PVD_{Shenshu (BL23)} and PVD_{Dachangshu (BL25)} exhibited trends consistent with disease course progression (P>0.05), with different degree (P<0.01). CONCLUSION The PVD_acupoint value based on Euclidean distance can characterize the pressure sensitivity features of traditional acupoints associated with disease. Multivariate statistical analysis of PVD_acupoint confirms that selecting the acupoint combination of Shenshu (BL23) and Dachangshu (BL25) for CNLBP is associated with the distribution of surrounding pressure-sensitive points and the pathological characteristics of the condition.

Objective:To investigate the status of iodine deficiency disorders in children and pregnant women in Ganzhou City, Jiangxi Province, and to provide a basis for scientific iodine supplementation and adjustment of prevention and control strategies.Methods:According to the requirements of the National Iodine Deficiency Disorders Surveillance Program (2016 Edition), iodine deficiency disorders surveillance was carried out in 18 counties (cities, districts) under the jurisdiction of Ganzhou City from 2018 to 2022. Edible salt and urine samples taken from children aged 8 to 10 and pregnant women were collected to detect salt and urine iodine levels. At the same time, B-ultrasound method was adopted to measure children's thyroid volume, and the goiter rate was calculated.Results:From 2018 to 2022, a total of 27 075 edible salt samples were collected from key populations (children aged 8 - 10 and pregnant women), with a median salt iodine of 25.00 mg/kg and a qualified iodized salt consumption rate of 96.24% (26 057/27 075). The difference in the qualified iodized salt consumption rate among key populations in different years was statistically significant (χ 2 = 29.09, P < 0.001). A total of 18 061 urine samples were collected from children, with a median urine iodine of 192.10 μg/L, there was a statistically significant difference in the urine iodine level of children between different years ( H = 82.59, P < 0.001). A total of 9 014 urine samples were collected from pregnant women, with a median urine iodine of 177.20 μg/L, there was a statistically significant difference in urine iodine level of pregnant women between different years ( H = 78.78, P < 0.001). A total of 8 621 children's thyroid glands were examined, including 34 cases of goiter, with a goiter rate of 0.39%, and the goiter rate showed a decreasing trend year by year (χ 2trend = 11.09, P < 0.001). Conclusions:From 2018 to 2022, the iodine nutrition of children and pregnant women in Ganzhou City is at an appropriate level, the consumption rate of qualified iodized salt (> 90%) and the children's goiter rate (< 5%) met the national iodine deficiency disorders elimination standards. Ganzhou City continues to maintain the status of eliminating iodine deficiency disorders.

To evaluate the efficacy and safety of endoscopic submucosal dissection (ESD) for rectal neuroendocrine tumor (RNET). Data of 71 patients (43 males and 28 females, aged 46.66±10.15 years) with histologically diagnosed RNET ≤15 mm in diameter who underwent ESD in Department One of Gastroenterology, Digestive Diseases Hospital, Heilongjiang Provincial Hospital from December 2012 to January 2021 were retrospectively analyzed. Epidemiological characteristics, endoscopic characteristics, the operation time, complications, pathology results, the consistency of endoscopic ultrasound (EUS) and pathology and prognosis were analyzed. Sixty-nine patients had single lesion and 2 patients had multiple lesions (two of each). Seventy lesions (70/73, 95.89%) were?located?in?the?middle-lower?rectal?segment, and 3 lesions (3/73, 4.11%) in the upper segment. The maximum diameter was 8.54±3.12 mm. The en bloc resection rate was 100%. No adverse event was observed. The R0 resection rate was 87.67% (64/73), with 8 had undetermined vertical resection margin and 1 had lymphovascular invasion. EUS showed no case involving the muscularis propria with pathologic coincidence rate of 100.0%. The follow-up period was 4.52±3.85 years (1-9 years). No local recurrence or distant metastasis was found. ESD is safe and effective in RNET ≤15 mm in diameter. For?tumors of G1 without metastasis in preoperative evaluation, close?follow-up?seems?to?be?a?feasible?option with lymphovascular invasion or undetermined margin after?ESD.

Objective To investigate the relationship between intelligence impairment and interictal epileptiform discharges spreading in mesial temporal lobe epilepsy(mTLE)patients. Method We assessed 145 patients diagnosed as mTLE and their general materials, analyzed the relationship between intelligence impairment and interictal epileptiform discharges spreading. Results ①Patients with mTLE with longer disease course and higher frequencies of epilepsy tended to have a severe impairment in the total intelligence quotient (IQ), verbal intelligence quotient (vIQ) and performance intelligence quotient (pIQ). ② IQ of was negatively correlated with the condition that interictal epileptiform discharges spreading to the ipsilateral central and parietal region in patients with left lesion; pIQ was negatively correlated with the condition that interictal epileptiform discharges spreading to the ipsilateral frontal region, while positively correlated with the condition that interictal epileptiform discharges spreading to the ipsilateral occipital region in patients with right lesion. Conclusion ①Intelligence impairment of mTLE patients is related with courses and frequencies.②Total IQ is more severely impaired by interictal epileptiform discharges spreading to the ipsilateral central and parietal region in left mTLE patients, and the pIQ is more severely impaired by interictal epileptiform discharges spreading to the ipsilateral frontal region in right mTLE patients.

Objective To investigate the status quo of preoperative urination training in the selective neurosurgical patients and to analyze reasons and its nursing strategies.Methods A self-designed questionnaire was used to investigate the status of preoperative urination training from April 2016.and reasons were analyzedand the nursing strategies were proposed.Meanwhile.the status of preoperative urination training for patients from August 2016 with nursing strategies was analyzed.Results Only 54％ of the selective neurosurgical patients performed preoperative urination training.Though patients were aware of the necessity of preoperative urination training.attached little importance to preoperative urination training.Therefore,the overall compliance rate was low than nursing before,but increased to 89％ after nursing.Conclusion The patient's compliance can be greatly improved by normalizing preoperative urination training methods and processes.adding urination training related knowledge and health education forms and contents.monitoring efficacy of health education.
