Objective To explore the risk factors of painful diabetic neuropathy (PDN) in patients with type 2 diabetes mellitus (T2DM). Methods A total of 269 patients with type 2 diabetes mellitus (T2DM) who were treated in the Department of Endocrinology at Zhangjiagang Hospital Affiliated to Soochow University from January 2020 to December 2024 were selected. The patients were divided into two groups: T2DM without PDN (n=190) and T2DM with PDN (n=79). The general characteristics and biochemical indicators of the two groups of patients were compared. Multivariate logistic regression was used to analyze the associated factors with PDN in T2DM. The receiver operating characteristic (ROC) curve was used to evaluate fasting C-peptide (FC-P), body mass index (BMI), and disease duration to predict the risk of PDN. Results Compared with the T2DM group without concurrent PDN, the T2DM group with concurrent PDN had a longer disease course, lower BMI, higher HDL-C, lower FC-P, and a higher proportion of diabetic retinopathy. The differences between the two groups were statistically significant (P<0.05). The results of multivariate logistic regression analysis showed that BMI, duration, and FC-P were associated factors of PDN. Conclusion BMI, duration and FC-P are associated factors of painful neuropathy complicated with type 2 diabetes.

Objective:To investigate the application and effect of a competency-oriented teaching model in standardized nutritional diagnosis and treatment training for clinical physicians.Methods:A blended teaching method combining online and offline lectures was used to teach core knowledge and skills of clinical nutrition among clinical physicians by implementing a step-by-step "popularization-strengthening-deepening" strategy. The number of nutritional consultations, the improvement in nutritional diagnosis and treatment among clinical physicians, and the degree of satisfaction after training were used as assessment indices.Results:Compared with the data in 2021, the number of annual nutritional consultations was increased by 21.41% in 2022 and 53.18% in 2023. A total of 281 clinical physicians received online deepening course training, among whom 237 (84.34%) completed the online clinical nutrition knowledge test, with a mean score of (86.17±5.48) points and a pass rate of 81.86% (194/237). The online training received a satisfaction rate of 80.39%.Conclusions:The training program designed with competency-based objectives, systematic content, and diverse methodologies can significantly enhance the standardized thinking and capabilities of clinical physicians in nutritional diagnosis and treatment.

Objective:To observe the effect of point injection at Zusanli(ST36)plus abdominal point application on gastrointestinal dysfunction after laparoscopic surgery.Methods:A total of 204 patients with gastrointestinal dysfunction after laparoscopic surgery were recruited and divided into four groups using the random number table method,with 51 cases in each group.The control group received conventional postoperative intervention.In addition to the treatment in the control group,the point injection group was given point injection at Zusanli(ST36),the application group was offered abdominal point application,and the integrated group received point injection at Zusanli(ST36)and abdominal point application.The treatment lasted 3 consecutive days in all four groups.The recovery time of gastrointestinal function indicators and the incidence rate of postoperative nausea and vomiting(PONV)were observed and recorded.Before and after treatment,the visual analog scale(VAS)was used to assess abdominal pain intensity,the venous blood type 1 helper T cells/type 2 helper T cells(Th1/Th2)was determined,the serum levels of interleukin(IL)-6 and interferon(IFN)-γ were detected using the enzyme-linked immunosorbent assay,and the plasma levels of motilin and gastrin were measured using radioimmunoassay.Results:Compared to the control group,the first exhaust time,the first defecation time,and the time of restoring fluid diet came earlier in the other three groups(P<0.05)and were earlier in the integrated group than in the point injection and application groups(P<0.05).The point injection,application,and integrated groups had a lower PONV incidence rate than the control group,and the integrated group was lower than the point injection and application groups(P<0.05).The intra-group comparisons showed that the VAS score and the levels of IL-6 and INF-γ decreased after treatment in all four groups(P<0.05);the point injection,application,and integrated groups were lower than the control group(P<0.05),and the integrated group was lower than the point injection and application groups(P<0.05).The intra-group comparisons also demonstrated that the levels of Th1/Th2,motilin,and gastrin increased after the intervention in the four groups(P<0.05);the point injection,application,and integrated groups were higher than the control group(P<0.05),and the integrated group was higher than the point injection and application groups(P<0.05).Conclusion:Point injection at Zusanli(ST36)plus abdominal point application can encourage postoperative exhaust,defecation,and the recovery of diet fluid,alleviate postoperative abdominal pain,reduce PONV,balance Th1/Th2,and regulate the secretion of motilin and gastrin in patients with gastrointestinal dysfunction after laparoscopic surgery.

OBJECTIVE: To review the application and progress of unilateral biportal endoscopy (UBE) technology in the treatment of cervical degenerative diseases, and to provide reference for clinical treatment decisions. METHODS: The literature related to UBE technology in the treatment of cervical spondylotic radiculopathy (CSR) and cervical spondylotic myelopathy (CSM) at home and abroad was extensively reviewed, and the surgical methods, indications, effectiveness, and safety were analyzed and summarized. RESULTS: UBE technology is effective in the treatment of CSR and CSM, and has the advantages of good surgical field, reducing the injury of the posterior structure of the cervical spine, and protecting the facet joint process, but in general, the indications are relatively narrow, limited to single-segment or adjacent double-segment lesions, and the requirements for the operator are relatively high, and the learning curve is long. CONCLUSION UBE technology can be applied to the treatment of CSR and CSM, but it needs to be carried out by experienced UBE surgeons for specific cases.

Objective: To analyze the distribution characteristics of immunoglobulin A (IgA) concentration in Nanning Zhuang blood donors by measuring the concentration of plasma IgA. Methods: Enzyme-linked immunosorbent assay (ELISA) was performed to measure the absorbance of 2 000 plasma samples from Zhuang blood donors. The IgA concentration in samples was calculated using the ELISA Calc regression/fitting technology program. Results: The standard curve demonstrated that ELISA detection of plasma IgA concentration exhibited good precision. The frequency of IgA deficiency was 0/2 000. No statistically significant difference in the distribution of IgA concentration was observed between males and females (P>0.05). The distribution of IgA concentration varied significantly across age groups: younger individuals (18-39 years old) had lower plasma IgA levels (mg/dL) compared to older individuals (40-56 years old): 5-89.99 mg/dL group, 8.80% (176/2 000) vs 17.20% (344/2 000); 90-450 mg/dL group,20.65% (413/2 000) vs 51.20% (1 024/2 000); >450 mg/dL group, 0.45%, (9/2 000) vs 1.70% (34/2 000), P<0.05. No significant difference in IgA concentration was found among different ABO blood types in Zhuang blood donors (P>0.05). Spearman correlation analysis revealed a positive correlation between age and IgA concentration (R =0.114, P<0.05). Conclusion: No individuals with IgA deficiency were screened out among the Zhuang blood donors in Nanning area, and plasma IgA levels progressively increase with age.

Objective:To investigate the effect of blood glucose control on the imaging severity and clinical symptoms of facet joint osteoarthritis (FJOA) in patients with type 2 diabetes mellitus (T2DM).Methods:A total of 286 patients with lumbar degenerative diseases who were diagnosed and treated in the Department of Spinal Surgery of the Third Affiliated Hospital of Sun Yat-sen University from December 2021 to December 2022 were retrospectively collected. Patients were divided into diabetic and non-diabetic groups according to whether T2DM was diagnosed at admission. Age, gender, presence of hypertension, and body mass index (BMI) were recorded. The duration of diabetes was recorded. Fasting blood glucose and peak postprandial blood glucose were monitored for 3 consecutive days. Plasma glucose and glycosylated hemoglobin were assessed by blood biochemical results. Diabetic patients were divided into three sub-groups according to fasting blood glucose and glycosylated hemoglobin levels (HbA1c): ideal blood glucose control (HbA1c<6.5% and fasting blood glucose<6.1 mmol/L), good (6.5%≤HbA1c≤7.5% or 6.1 mmol/L≤fasting blood glucose≤7.0 mmol/L), and poor (HbA1c>7.5% and fasting blood glucose>7.0 mmol/L). Visual analogue scale (VAS) was used to assess the degree of low back pain. Pathria grading system was used to assess the severity of FJOA at different levels of the lumbar spine on lumbar CT. Mann-whitney U test was used to compare the difference of FJOA between L 1-S 1 segments in diabetic and non-diabetic patients. Logistic regression was used to analyze the effect of diabetes on FJOA. Kruskal-Wallis test was used to compare the difference of FJOA between different segments in diabetic patients among different sub-groups. Logistic regression was used to analyze the effect of blood glucose control on FJOA. Results:A total of 121 patients in the diabetic group and 165 patients in the non-diabetic group were included. L 4, 5 FJOA grade 3(2, 3) in diabetic patients was greater than grade 2(1, 3) in non-diabetic patients with significant difference ( Z=-3.179, P=0.001), and diabetes was an independent risk factor for L 4, 5 FJOA [ OR=1.767, 95% CI(1.032, 3.025), P=0.038]. There was no significant difference in age, BMI, sex ratio, prevalence of hypertension and blood glucose fluctuation values among different subgroups of glycemic control in the diabetic group. Patients in the poor glucose group had higher FJOA grades 2(1, 2), 3(3, 3) and 3(2, 4) at L 1, 2, L 4, 5 and L 5S 1 than those in the ideal glucose group at grades 1(1, 2), 2(1.5, 3) and 2(1, 2) with significant differences ( H=9.530, P=0.009; H=18.248, P<0.001; H=27.916, P<0.001). Patients in the poor glucose group had higher grades 3(3, 3) and 3(2, 4) of osteoarthritis of the L 4, 5 and L 5S 1 facet joints than those in the good glucose group, grades 3(2, 3) and 2(1, 2) with significant differences ( H=18.248, P<0.001; H=27.916, P<0.001). Low back pain was positively correlated with poor glycemic control, L 4, 5 and L 5S 1 FJOA ( r=0.512, P<0.001; r=0.383, P<0.001; r=0.484, P<0.001). Poor glycemic control was an independent risk factor for FJOA at L 4, 5 and L 5S 1 [ OR=4.963, 95% CI (1.095, 22.496), P=0.038; OR=6.010, 95% CI(1.061, 34.049), P=0.043]. Conclusion:Compared with non-diabetic patients, patients with type 2 diabetes have a higher risk of osteoarthritis in the facet joints of L 4, 5. Compared with diabetic patients with good or ideal glycemic control. Patients with poor glycemic control had more severe osteoarthritis of the L 4, 5 and L 5S 1 facet joints. Patients with severe facet joint degeneration and poor glycemic control often suffered more from severe low back pain.
