Objective:To investigate the effect of nourishing yin and tonifying yang method on inflammatory response and bone metabolism in patients with T2DM complicated with osteoporosis (OP).Methods:A randomized controlled trial. From January 2022 to December 2023,80 patients with T2DM and OP in our hospital were selected as the observation objects, and they were divided into two groups by random number table method, with 40 cases in each group.On the basis of conventional treatment, the control group chewed vitamin D calcium chewable tablets, and the observation group added nourishing yin and tonifying yang Chinese medicine.Both groups were treated for 6 months. TCM syndrome scores were performed before and after treatment ;the levels of fasting blood glucose (FPG), 2 hPG and HbA1c were detected by intelligent blood glucose monitor;the levels of serum neutrophils and lymphocytes were detected by automatic blood analyzer, and the neutrophil/lymphocyte ratio (NLR) was calculated;the levels of serum IL-1β and TNF-α were detected by automatic chemiluminescence analyzer, the levels of type I procollagen amino terminal propeptide (PINP), type I collagen carboxy terminal peptide β special sequence (β-CTX) and 25-hydroxy vitamin D3 [25-(OH)D3] were detected by ELISA;Bone mineral density (BMD) was detected by bone mineral density detector. The adverse reactions during treatment were observed and recorded, and the clinical efficacy was evaluated.Results:The total effective rate was 92.5 %(37/40) in the observation group and 75.0 % (30/40) in the control group,the difference between the two groups was statistically significant ( χ2=4.50, P=0.034).After treatment, the scores of soreness and weakness of waist and knees, soreness and pain of waist and back, clear and long urine, pale tongue and white coating in the observation group were lower than those in the control group ( t=3.11, 3.75, 3.51, 3.74, P<0.01);the levels of serum FPG, 2 hPG and HbA1c in the observation group were lower than those in the control group ( t=3.11,3.20,3.39, P<0.01).The levels of serum NLR (2.63 ± 0.68 vs. 3.24 ± 0.79, t=3.70), IL-1β [(81.65 ± 8.30) ng/L vs. (89.03 ± 8.98) ng/L, t=3.82] and TNF-α [(35.14 ± 5.11) μg/L vs. (39.96 ± 5.38) μg/L, t=4.11] in the observation group were lower than those in the control group ( P<0.01). After treatment, the levels of PINP [(29.83 ± 3.92) ng/L vs. (34.02 ± 4.03) ng/L, t=4.71] and β-CTX [(21.30 ± 3.95 ) ng/L vs. (25.32 ± 4.18) ng/L, t=4.42] in the observation group were lower than those in the control group ( P<0.01), the levels of 25-(OH)D3 [(42.86 ± 5.12) μg/L vs. (38.08 ± 4.55) μg/L, t=4.41] and BMD [(0.90 ± 0.18) g/cm 3vs. (0.78 ± 0.16) g/cm 3, t=3.15] were higher than those in the control group ( P<0.01).During the treatment, the incidence of adverse reactions was 12.5% (5/40) in the observation group and 10.0 % (4/40) in the control group,there was no significant difference between the two groups ( χ2=0.13, P=0.723). Conclusion:The method of nourishing yin and tonifying yang can effectively improve the TCM syndromes of T2DM patients with OP, reduce the levels of blood glucose and inflammatory factors, improve bone metabolism, improve clinical efficacy and have good treatment safety.

Post traumatic depression (PTD) is a serious complication after traumatic brain injury, with high incidence rate; PTD seriously affects the rehabilitation, outcome and quality of life of patients. Due to unclear pathogenesis of PTD, effective treatments have not yet been found in clinical practice. Repetitive transcranial magnetic stimulation (rTMS), as a new non-invasive neuroregulatory technique, has been used in major depression disorder (MDD). Few clinical evidence on PTD treated by rTMS is noted and optimal rTMS treatment regimen has not yet been defined.This article reviews the clinical studies of rTMS in PTD in recent years, with a view to provide references for clinical application.

Objective:To compare the clinical outcomes between percutaneous Kirschner wire leverage plus plaster fixation and elastic intramedullary nailing in the treatment of radial neck fractures in children.Methods:A retrospective study was conducted to analyze the 60 children with radial neck fracture who had been treated by percutaneous Kirschner wire leverage plus plaster fixation at Department of Pediatric Orthopedics, Children's Hospital of Soochow University from January 2016 to July 2023 (set as an internal fixation-free group). They were 30 males and 30 females (34 left and 26 right sides) with an age of (7.7±3.0) years. At the same time, another cohort of 60 patients were chosen as an intramedullary nailing group who had been treated by percutaneous Kirschner wire leverage plus elastic intramedullary nailing and matched in age and gender with those in the internal fixation-free group. The preoperative fracture angulation, operative time, hospitalization time, fracture angulation on the first postoperative day, fracture angulation at 1 month postoperatively, rate of angulation loss after reduction, Mayo elbow performance score (MEPS) at the last follow-up and complications were compared between the 2 groups.Results:There was no significant difference between the 2 groups in their preoperative general data, showing comparability ( P<0.05). The 120 pediatric patients were followed up for (7.5±3.2) months. The operative time [(27.4±15.0) min] and hospitalization time [(3.4±1.9) d] in the internal fixation-free group were significantly shorter than those in the intramedullary nailing group [(45.4±13.5) min and (4.4±1.3) d] ( P<0.05). The preoperative fracture angulation (50.8°±1.9°), fracture angulation on the first postoperative day (11.3°±1.2°), fracture angulation at 1 month postoperatively (12.1°±1.3°), rate of angulation loss after reduction (2.9%±0.5%), and MEPS at the last follow-up [(90.4±2.0) points] in the internal fixation-free group showed no significant differences from those in the intramedullary nailing group [49.5°±1.7°, 11.1°±1.2°, 13.3°±1.5°, 3.9%±1.4%, and (90.2±2.3) points] ( P>0.05). None of the patients in the internal fixation-free group developed pin-tail irritation sign or premature epiphyseal closure after surgery, whereas 3 patients in the intramedullary nailing group developed pin-tail irritation sign and 2 ones premature epiphyseal closure after surgery, showing a significant difference in the complication rate between the 2 groups [0 (0/60) versus 8.3% (5/60)] ( P<0.05). Conclusions:Percutaneous Kirschner wire leverage plus plaster fixation and close elastic intramedullary nailing can both achieve satisfactory outcomes in the treatment of radial neck fractures in children. However, percutaneous Kirschner wire leverage plus plaster fixation needs shorter operative time and hospitalization time, leads to fewer complications, and requires no reoperation to remove internal fixation.

Objective To investigate the effect of cornus officinalis glycosides on apoptosis and oxidative damage of human renal tubular epithelial cells line induced by high glucose by regulating E2-related factor 2(Nrf2)/heme oxygenase-1(HO-1)pathway.Methods Human renal tubule epithelial cell line HK-2 was divided into control group(control,5.5 mmol/L glucose),model group(HG,30 mmol/L glucose),and total cornus offici-nalis glycosides groups with low,medium and high dose(L-COG,M-COG,H-COG).After Nrf2 pathway inhibitors were added,HK-2 cells were divided into H-COG group and ML385 group.CCK8 method was used to detect cell activity.Apoptosis was detected by flow cytometry.The expressions of Bcl-2 associated X protein(Bax),B-cell lymphoma/leukemia 2(Bcl-2),activated caspase3(cleaved caspase3),Nrf2/HO-1 pathway protein were detected by Western blot.Reactive oxygen species(ROS)content was detected by DCFH-DA,glutathione peroxi-dase(GSH-Px)activity,superoxide dismutase(SOD)activity,interleukin-6(IL-6)content and tumor necrosis factor α(TNF-α)content were detected by ELISA.Results Compared with control group,the cell activity,Bcl-2 protein expression,GSH-Px and SOD activity in model group were significantly decreased,and the apoptosis rate,Bax,Nrf2,HO-1 and cleaved caspase3 protein expression,ROS,IL-6 and TNF-α content were significantly in-creased(P＜0.05).Compared with model group,the cell activity,Bcl-2 protein expression,GSH-Px and SOD ac-tivity of L-COG,M-COG,and H-COG were significantly increased.Apoptosis rate,Bax,Nrf2,HO-1,cleave-caspase3 protein expression,ROS,IL-6,TNF-α content were significantly decreased(P＜0.05).Compared with H-COG,the cell activity,Bcl-2 protein expression,GSH-Px and SOD activity in ML385 group were significantly increased.The apoptosis rate,Bax and cleaved caspase3 protein expression,ROS,IL-6,TNF-α content were sig-nificantly decreased(P＜0.05).Conclusions The total cornus officinis glucoside may reduce the oxidative stress and inflammatory response of renal tubular epithelial cells induced by high glucose through inhibiting Nrf2/HO-1 pathway and then reduce cell apoptosis.

Clinical data of a teenager with slipped capital femoral epiphysis (SCFE) combined with primary hyperparathyroidism (PHPT) treated in the Children′s Hospital of Soochow University in May 2022 were retrospectively analyzed.A girl, aged 13 years and 5 months, had claudication of both lower limbs for 1.5 years, and the symptom was aggravated for 1 month.X-ray examination of the hip joint showed bilateral SCFE.However, the patient had a body mass index of 18.2 kg/m 2 and no trauma, which did not meet the typical characteristics of SCFE.Further ultrasound examination of the parathyroid gland shows parathyroid adenoma.And parathyroid adenoma was considered to cause PHPT, which in turn triggered SCFE.After surgical resection of the PHPT, the patient had a better fusion of the femoral head and femoral neck and improved hip joint function.Therefore, SCFE fixation was not performed.The diagnosis and treatment of this patient indicated that for similar patients with SCFE and PHPT, SCFE may not be treated with internal fixation, if the femoral head and femoral neck have been fused, the hip joint function has improved, and the pain has been relieved after resection of PHPT.In patients with SCFE and PHPT, the management of hyperparathyroidism takes precedence over the treatment of SCFE.Acute and acute-on-chronic slip, with or without PHPT-induced hypercalcemia, should be treated first by SCFE fixation, and excising parathyroid adenoma should be performed simultaneously or as soon as possible.For chronic slip patients who have mild to moderate hypercalcemia and one or more related symptoms, parathyroidectomy should be performed firstly, and then the SCFE fixation should be considered after parathyroid hormone and blood calcium levels become stable.
