OBJECTIVE: To investigate short-term effectiveness of robot-assisted fracture reduction and fixation combined with arthroscopic exploration for posterolateral depressed tibial plateau fractures. METHODS: Between January 2022 and January 2024, 8 patients with posterolateral depressed tibial plateau fractures (Schatzker type Ⅲ) were treated using robot-assisted fracture reduction and fixation combined with arthroscopic exploration, with simultaneous treatment of concomitant ligament or meniscus tears. There were 3 males and 5 females with an average age of 54.1 years (range, 42-68 years). Injury mechanisms included traffic accidents (3 cases) and falls (5 cases). The time from injury to operation ranged from 2 to 4 days (mean, 3.1 days). Operation time, intraoperative blood loss, hospital stay duration, visual analogue scale (VAS) score for pain, and complications were recorded. Fracture healing and knee Rasmussen scores were assessed radiographically, while knee function was evaluated using range of motion and Hospital for Special Surgery (HSS) scores. RESULTS: All operations were successfully completed. The operation time was 108-129 minutes (mean, 120.1 minutes). The intraoperative blood loss was 10-100 mL (mean, 41.3 mL). The hospital stay duration was 4-7 days (mean, 5.6 days). All incisions healed by first intention without complication such as peroneal nerve injury, vascular damage, or infection. All patients were followed up 32-48 weeks (mean, 40 weeks). Radiographic follow-up confirmed that the knee Rasmussen scores rated as excellent in 8 patients and all fractures healed with the healing time of 12-16 weeks (mean, 13.5 weeks). The VAS score for pain was 2-4 (mean, 2.8) at discharge and improved to 0 at 1 month after operation. The knee range of motion was 80°-110° (mean, 96.1°) at discharge and increased to 135°-140° (mean, 137.9°) at 1 month after operation. At 3 months after operation, the HSS score was 91-94 (mean, 92.8), all graded as excellent. No severe complication, including implant failure, occurred during follow-up. CONCLUSION For posterolateral depressed tibial plateau fractures, the minimally invasive approach combining robot-assisted fracture reduction and fixation with arthroscopic exploration demonstrates multiple advantages, including shorter operation time, reduced intraoperative blood loss, excellent wound healing, fewer complications, and rapid recovery of knee function. This technique achieves satisfactory short-term effectiveness, while its long-term effectiveness requires further evaluation.

Objective: To analyze the effect and adverse reactions of radiotherapy in patients with primary orbital lymphoma. Methods: A total of 28 patients with primary orbital lymphoma from Tianjin Union Medical Center, the First Central Hospital of Tianjin and Tianjin Dagang Oil Company Hospital between March 2006 and August 2012 were retrospectively analyzed. All the patients received orbital tumor dissection or biopsy, then received radiation therapy. Three patients received chemotherapy with CHOP protocol before radiotherapy. Radiotherapy was delivered routinely with 3D-conformal radiation therapy (CRT) technique with daily 2-2.5 Gy for 5 times per week and 3-5 fields. Total dosage was 20-50 Gy. There were 18 cases of 30 Gy, 1 case of 22 Gy, 1 case of 25 Gy, 1 case of 20 Gy, 1 case of 28.8 Gy, 3 cases of 40 Gy, 1 case of 42 Gy, 1 case of 46 Gy and 1 case of 50 Gy. Results: All the patients had complete remission (CR) after radiotherapy during follow-up. One patient recurred after radiotherapy of 4 months and received CR with radiotherapy again. One patient died of lung infiltration. Acute complications during radiotherapy were conjunctivitis (28 cases, 100.0%) and keratitis (1 case, 3.6%), long-term complications with ophthalmoxerosis (10 cases, 35.7%) and decreased visual acuity (1 case, 3.6%). Conclusion Radiotherapy is an effective method for primary orbital lymphoma, and the adverse reactions can be tolerated for most patients.

OBJECTIVETo explore the risk factors and their differences of metabolic syndrome (MS) on male criminal police, thereby provide the scientific basis to make prevention and control strategies about the metabolic syndrome for the criminal police career.

METHODSBased on physical examination data of criminal police in 2010, 439 patients with MS (CDS) were randomly selected as cases. And as the 1:2 matched nested case-control study, 878 health controls were employed, which were matched with on the basis of sex and age (±1 year). An face-to-face epidemiological investigations on the past exposure status of several possible risk factors was conducted, such as the family history of hypertension and other social economic status, as well as body height and weight, waist circumference, blood pressure, serum lipid and plasma sugar. and the data were analyzed with logistic regression.

RESULTS1317 cases were surveyed, through single factor logistic regression analysis found that 12 factors are related to exposure. Multivariate logistic regression analysis suggested that six factors, such as stress events (OR = 1.989, 95%CI: 1.467∼2.696), snoring (OR = 1.672, 95%CI: 1.218∼2.294), sweets (OR = 0.562, 95%CI: 0.412∼0.766), meat and products (OR = 1.494, 95%CI: 1.065∼2.094), siting after dinner for more than 3 h (OR = 1.399, 95%CI: 1.023∼1.915).

CONCLUSIONSMS has become a important public health problems among criminal police. For their professional special, a series of bad habits , unhealthy life style and psychological problems became important risk factors of MS on criminal police. Targeted prevention and control measures should be taken to reduce the incidence of MS.
