BACKGROUND: Femoral neck fractures can be treated with cannulated screws, dynamic hip screws, locking plates, and intramedullary nails. However, there are still high risks of internal fixation failure, femoral neck shortening, varus deformity, femoral head necrosis and nonunion. The femoral neck system is minimally invasive and provides stable rotation resistance with minimal screw cutting and screw withdrawal. OBJECTIVE: To compare early clinical effects of femoral neck system and femoral neck system combined with cannulated screw on femoral neck fracture. METHODS: The data of 42 patients with femoral neck fracture treated in Department of Orthopedics, Baoding First Central Hospital from March 2020 to October 2021 were retrospectively analyzed. Of them, 33 patients were followed up and divided into femoral neck system group (group A; n=26) and femoral neck system combined with cannulated screw group (group B; n=7). Operation time, intraoperative fluoroscopy times, intraoperative blood loss, length of hospital stay, fracture healing time, curative effect (Harris score) and complications at the last follow-up were recorded. RESULTS AND CONCLUSION: (1) Thirty-three patients were followed up for 3-19 months. (2) Operation time, intraoperative fluoroscopy times, and intraoperative blood loss were significantly less in group A than those in group B (P < 0.05). Length of hospital stay and Harris score postoperatively and at final follow-up were not significantly different (P > 0.05). Hip function was evaluated as follows: excellent in 15 cases, good in 9 cases, and average in 2 cases in group A; excellent in 6 cases and good in 1 case in group B. (3) Postoperative X-ray films showed that all fractures healed, and the healing time was 3-6 months, with an average of 4.5 months. (4) There was no significant difference in the degree of femoral neck shortening between the two groups after operation and at the final follow-up (P > 0.05). (5) None of the patients had complications such as infection and loosening of internal fixation during follow-up. (6) The treatment of femoral neck fractures with femoral neck system or combined with cannulated screw fixation is simple and minimally invasive with satisfactory short-term results.

BACKGROUND: The posterolateral approach is the most commonly used surgical approach for total hip arthroplasty. In recent years, total hip replacement by direct anterior approach has been applied in clinic gradually, and has achieved good treatment outcomes. OBJECTIVE: To compare the clinical efficacy of the direct anterior approach in supine position and the posterolateral approach in supine position for total hip arthroplasty. METHODS: Ninety patients undergoing unilateral primary total hip arthroplasty at Baoding Municipal First Center Hospital from April 2015 to April 2019 were included, including 35 males and 55 females, aged 35-70 years. The patients were divided into direct anterior approach group (n=45) and posterolateral approach group (n=45) by the random number table method. Postoperative follow-up was used to evaluate the Harris hip scores, Visual Analogue Scale scores, initial fixation mass of prosthesis and safe range of the cup. The study was approved by the Ethics Committee of Baoding Municipal First Center Hospital. RESULTS AND CONCLUSION: (1) Ninety patients were followed up for 3-51 months, with an average 14 months. There were 2 cases of intraoperative great trochanteric fracture, 1 case of femoral lateral cutaneous nerve injury, 4 cases of femoral nerve injury, and 20 cases of tensor fascia lata injury. No such complications occurred in the posterolateral approach group. (2) The direct anterior approach group showed significant superior outcomes compared with the posterolateral approach group in the Harris hip scores and Visual Analogue Scale scores at 1 month after surgery (P < 0.05). The scores showed no significant differences between two groups at the last follow-up (P > 0.05). (3) In the direct anterior approach group, the femoral prosthesis of 44 hips was in neutral position, and 1 hip was in varus position. The initial fixation quality of all prosthesis was excellent. In the posterolateral approach group, the femoral prosthesis of 43 hips was in neutral position, 2 hips were in varus position and all prosthesis initial fixation quality was excellent. No significant difference was found between two groups (P > 0.05). (4) The ratio of acetabular cups in the safety range of Lewinnek in the direct anterior approach group was higher than that in the posterolateral approach group (100%, 82%, P < 0.05). (5) These results imply that compared with the posterolateral approach, direct anterior approach in supine position for total hip arthroplasty can significantly reduce postoperative pain, promote postoperative early rapid recovery, obtain more accurate angle of the acetabular prosthesis, and be more conducive to the equalization of both lower limbs. It is a safe and reliable approach. However, direct anterior approach has certain technical difficulty and needs a learning curve. And there are some complications different from other approaches.

OBJECTIVE: To probe into the effect of early immune enteral nutrition on postoperative immune status and prognosis in patients with gastric cancer. METHODS: 76 patients undergoing radical operation for gastric cancer admitted into the First Hospital of Hohhot from Jan. 2015 to May 2017 were selected and divided into obervation group and control group via random number table, with 38 cases in each group. The observation group was given early immune enteral nutrition, while the control group was given total parenteral nutrition. At 1 day before operation and 8 days after, levels of immune cell subset and immune globulin(Ig), indices of nutritional status [serum total protein(TP), pre-albumin(PA) and albumin(ALB)], inflammatory factor levels [interleukin 10(IL-10), tumor necrosis factor α(TNF-α), interferon-γ(IFN-γ) and interleukin 2(IL-2)], incidences of complications and 1-year progression-free survival of both groups were observed. RESULTS: At 8 days after operation, the CD4~+, CD4~+/CD8~+, natural killer cell and natural killer T-cell levels of observation group were significantly higher than those of before treatment and the control group; the IgA, IgM and IgG levels of observation group were significantly higher than those of the control group; the TP, PA and ALB levels of observation group were significantly higher than those of the control group;the IL-10 and TNF-α levels of observation group were significantly lower than those of the control group, the IFN-γ and IL-2 levels were significantly higher than the control group, with statistically significant differences(P<0.05). The incidence of postoperative complications of observation group was significantly lower than that of the control group, and the 1-year progression-free survival was significantly higher than the control group, with statistically significant differences(P<0.05). CONCLUSIONS: Early immune enteral nutrition can improve postoperative immunologic function and nutritional status for patients with gastric cancer, reduce the incidence of complications and improve 1-year progression-free survival rate.
