Objective To summarize the effectiveness of 3.5 mm T support plate fixation for simple postero-lateral tibial plateau fractures by posterolateral inverted L-shaped approach. Methods Between March 2011 and January 2016, 13 patients with simple posterolateral tibial plateau fracture were treated with 3.5 mm T support plate fixation by posterolateral inverted L-shaped approach. Of 13 cases, 6 were male and 7 were female, aged 28 to 52 years (mean, 43 years). The left side was involved in 5 cases and the right side in 8 cases. The causes of injury were traffic accidents in 6 cases, falls in 3 cases, and falling from height in 4 cases. All of patients had fresh closed fracture by X-ray, CT three dimensional reconstruction, and MRI. According to Schatzker classification, 4 cases were rated as type II and 9 cases as type III. The time between injury and operation was 5-9 days (mean, 7 days). Results One case had incision skin necrosis, which was cured after debridement and skin grafting; and primary healing was obtained in the other cases. The patients were followed up 10-16 months (mean, 13 months). The X-ray film showed that the fracture line was blurred at 3 months after operation, and disappeared at 12 months after operation. There was no complications of wound infection, major neurovascular injury, loosening or breakage of internal fixation, and dislocation of joint surface. The Hospital for Special Surgery (HSS) knee function score was 94 (range, 89-97) at last follow-up; all were excellent. Conclusion The 3.5 mm T support plate fixation by posterolateral inverted L-shaped approach is one of preferred surgical method for the treatment of simple posterolateral tibial plateau fractures.
ObjectiveTo summarize the experience of diagnosis and treatment of a case of adult hepatic fibrohistiocytoma with recurrent rupture and hemorrhage.MethodsRetrospective analysis on this case of recurrent adult fibrohistiocytoma with rupture and hemorrhage admitted to Shengjing Hospital Affiliated to China Medical University in May 2018 was conducted, discussion on MDT was conducted before surgery, and the causes of recurrent rupture and hemorrhage, as well as the experience of diagnosis and treatment were summarized and analyzed.ResultsThis patient was generally in good condition. After MDT discussions among the imaging department, oncology department, interventional department, and hepatobiliary surgeons, it was considered that surgical treatment was the best treatment scheme. After full communication with the patient and his family, the patient had chosen open tumor resection and the operation was smooth. The operation time was 278 min, intraoperative bleeding was about 100 mL, and no blood transfusion was performed. No bleeding, abdominal infection, gastroparesis, and other complications occurred after the operation, and the patient was discharged successfully on the 13th day after the operation. The patient had been interviewed for 8 months and the tumor recurred again 1 month ago. Currently, oral apatinib had been targeted for treatment for more than 1 month, and the follow-up treatment continued.ConclusionsRecurrent adult fibrous histiocytoma with rupture and hemorrhage is rare in clinical practice, and the treatment is mainly based on surgical resection. Postoperative comprehensive treatment combined with radiotherapy, chemotherapy, molecular targeting, and immunotherapy is the main treatment. Its short-term efficacy is satisfactory, but long-term efficacy still needs to befurther observed.
ObjectiveTo investigate the role of endoplasmic reticulum stress in liver regeneration after associating liver partition and portal vein ligation for staged hepatectomy (ALPPS).MethodsSeventy-two C57bl/6 mice were randomly divided into ALPPS group, portal vein ligation group (PVL group), and sham operation group (Sham group), 24 mice in each group. And then one-stage ALPPS operation, simple PVL, and sham operation will be performed. Six mice were randomized selected of the three groups on the 1st, 2nd, 4th, and 7th day after surgery, respectively, the liver weight to body weight ratio (FLR/BW) of each group was measured, and the liver tissues were taken for immunohistochemical staining to calculate the proportion of Ki-67 positive cells, Western blot was used to detect the expression levels of X-box binding protein 1 (XBP1) and inositol-requiring enzyme 1α (IRE1α) proteins.Results① FLR/BW: On the 4th day and the 7th day after operation, the FLR/BW of the Sham group, PVL group, and ALPPS group increased in sequence at the same time, and the difference between the three groups was statistically significant (P<0.05). ② Ki-67 positive cell ratio: On the 2nd day after operation, the ratio of Ki-67 positive cells in the Sham group, PVL group, and ALPPS group increased sequentially, and the difference between the two groups was statistically significant (P<0.05). On the 4th day after operation, the ratio of Ki-67 positive cells in the PVL group and the ALPPS group were still higher than that of the Sham group (P<0.05). ③ Expression levels of XBP1 and IRE1α: On the 2nd and 4th postoperative day, the expression levels of XBP1 and IRE1α in the ALPPS group were higher than those in the Sham group and the PVL group (P<0.05). On the 7th day after surgery, the expression levels of XBP1 and IRE1α in the ALPPS group were higher than those in the Sham group (P<0.05), while compared with the PVL group, the expression level of XBP1 in the ALPPS group was still higher (P<0.05).ConclusionsALPPS-induced liver regeneration is more advantageous than traditional PVL in mice. It may be attributed to the obvious endoplasmic reticulum stress activation after ALPPS leading to the up-regulation of IRE1α-XBP1 expression, which is involved in the regulation of hepatocyte cell cycle and promotes hepatocyte proliferation, thus promoting rapid liver regeneration.

Objective To design a new type of three-dimensional honeycomb guide for percutaneous cannulated screw placement in femoral neck fracture and evaluate its effectiveness. Methods The clinical data of 40 patients with femoral neck fracture who met the selection criteria between June 2019 and December 2020 were retrospectively analyzed. According to different intraoperative positioning methods, they were divided into control group (20 cases, free hand positioning screws) and study group (20 cases, new guide assisted positioning screws). There was no significant difference in gender, age, side, cause of injury, Garden classification, and time from injury to operation between the two groups (P>0.05). The operation time, fluoroscopy times, guide needle puncture times, and fracture healing time of the two groups were recorded. The hip function was evaluated by Harris score at last follow-up. At immediate after operation, the following imaging indexes were used to evaluate the accuracy of screw implantation distribution: screw spacing, screw coverage area, distance from screw to cervical cortex, parallelism between screws, and screw to cervical axial deviation. Results All operations were successfully completed, and the guide needle did not penetrate the femoral neck cortex. There was no significant difference in operation time and fluoroscopy times between the two groups (P>0.05); the guide needle puncture times in the study group was significantly less than that in the control group (t=8.209, P=0.000). Imaging detection at immediate after operation showed that the screw spacing and screw coverage area in the study group were significantly greater than those in the control group (P<0.05); the distance from screw to cervical cortex, parallelism between screws, and screw to cervical axial deviation were significantly smaller than those in the control group (P<0.05). All patients were followed up 7-25 months, with an average of 19.3 months. There was no significant difference in follow-up time between the two groups (t=−0.349, P=0.729). There were 2 cases of fracture nonunion in the control group and 1 case in the study group, and the other fractures completely healed. One case of osteonecrosis of the femoral head occurred in the control group. During the follow-up, there was no complication such as vascular and nerve injury, venous thrombosis, screw penetration, withdrawal, breakage, and refracture, etc. There was no significant difference in fracture healing time and Harris score at last follow-up between the two groups (P>0.05). ConclusionThe new three-dimensional honeycomb guide has the advantages of simple structure and convenient use. It can reduce the puncture times of the guide needle and effectively improve the accuracy distribution of cannulated screw implantation.
