Objective:To evaluate the various wire tension belt ventral compression wiring technologiesfor treating several types of femoral greater trochanter fractures in total hip replacement, according to the different types of greater trochanter of femur fractures.Methods:From March 2013 to June 2019, a total of 1 280 cases of primary total hip arthroplasty were completed in our hospital, 21 patients with greater trochanter fractures were identified in total hip replacement. There were 11 males and 10 females with an average age of 65.81±6.45 years (range 42-76 years). All of them were unilateral. There were 11 cases on the left and 10 cases on the right. There were 11 cases of osteoarthritis secondary to hip dysplasia, 4 cases of hip osteoarthritis, 4 cases of aseptic necrosis of femoral head and 2 cases of femoral neck fracture. Different wire tension belt ventral compression wiring technologies were used for each fracture type. Harris hip function score, Parker activity score, and visual analogue scale (VAS) score of hip pain were evaluated during follow-up. X-ray films were taken to evaluate the fracture healing, prosthesis position, loosening and dislocation.Results:Three new fracture types were proposed: A transverse fracture from the greater trochanter tip to the base (4 cases); B oblique fracture from the greater trochanter tip to the base (according to the fracture line direction, type B was further divided into types B1 (4 cases) and B2 (6 cases); and C fracture line from the greater trochanter to subtrochanteric plane (7 cases). Among the 21 patients, one died at an early stage, two were lost during follow-up, and 18 were followed up for an average of 30.7±7.6 months. In 18 patients, the mean operation time was 110.0±20.0 min, and the mean intraoperative blood loss was 356.9±115.7 ml. The patients' Harris score was 35.26±5.52 at the preoperative, 65.7±6.42 at the 3 months after operation, and 87.75±6.21 at the final follow-up. The difference was statistically significant ( F=377.23, P<0.001). The patients' Parker score was 2.17±0.98 at the preoperative, 5.94±1.11 at the 3 months after operation,and 8.01±0.77 at the final follow-up. The difference was statistically significant ( F=170.96, P<0.001). The patients' VAS score was 6.22±1.11 at the preoperative, 2.61±0.92 at the 3 months after operation, and 1.28±0.67 at the final follow-up. The difference was statistically significant ( F=139.71, P<0.001). Deep vein embolism, heterotopic ossification was noted in one and another patient, respectively. The patient with non-union refused reoperation and had a broken steel wire, lower-limb limp, and no notable pain at the 12-month follow-up examination. Radiographs of 17 patients showed good location of the femoral prosthesis and no chronic pain. Conclusion:Different types of greater trochanter fractures in total hip arthroplasty were proposed, using different wire tension belt ventral compression wiring technologies for the various types of femoral greater trochanter fractures during total hip replacement can improve clinical outcomes.

AIM: To explore the clinical efficacy of three different kinds of Chinese patent medicines combined with tacrolimus and hormone in the treatment of nephrotic syndrome (NS). METHODS: A total of 199 patients with NS treated in department of nephrology of our hospital from January 2018 to December 2020 were analyzed retrospectively. All patients were treated with tacrolimus combined with hormone regimen for 12 weeks. According to different treatment schemes, they were divided into 4 groups: 57 cases in the control group, 51 cases in the Bailing capsule group (Bailing group), 55 cases in the Huangkui capsule group (Huangkui group) and 36 cases in the Wuzhi capsule group (Wuzhi group). The general data of patients, the biochemical indexes before and after treatment, and the tacrolimus blood concentration were collected. RESULTS: After 12 weeks of treatment, 24 h UTP and ALB of each group were statistically different (P<0.01). Compared with the control group, Bailing group had statistically significant differences in the reduction of TG and TC (P<0.05), Huangkui group had statistically significant differences in the reduction of 24 h UTP and serum TC (P<0.05), Wuzhi group had statistically significant differences in the reduction of 24 h UTP and AST (P<0.05). The steady-state trough concentration (C

AIM: To establish an ultra high performance liquid chromatography (UPLC) method for the determination of micafungin in plasma of critically ill patients. And to establish a model for estimating the area under the concentration-time curve (AUC) of micafungin by limited sampling strategy. METHODS: Patients with severe infection were administrated with micafungin once a day, 1 h for each infusion. The blood samples were collected before administration and 1, 2, 4, 8, 12, 24 h after administration and were measured by UPLC. The pharmacokinetic parameters were calculated by Phoenix winnonlin 6.4, and the drug concentrations at 2-4 blood collection points were analyzed with SPSS 22.0 to establish limited sampling models. RESULTS: The calibration curve was linear over a concentration range of 1.0 to 50 μg/mL (r
