[Comparison of therapeutic effects of arthroscopic popliteal cyst internal drainage and capsular wall resection].

OBJECTIVE: To investigate efficacy between arthroscopic popliteal cyst drainage and arthroscopic popliteal cyst resection. METHODS: From January 2013 to June 2021, 54 patients with popliteal cyst (Rausching-Lindgren gradeⅠto Ⅲ) were treated with arthroscopic surgery. There were 24 males and 30 females. The age ranged from 44 to 72 years old, with a mean of (62.67±6.08) years old. The course of the disease ranged from 1 to 72 months, with a mean of(15±14) months. Twenty-four patients (group A) were underwent arthroscopic internal drainage of popliteal cyst. Thirty patients (group B) were underwent arthroscopic resection of popliteal cyst. Preoperative main symptoms included knee pain, swelling, walking pain, popliteal swelling, popliteal mass and so on. After 1, 3, 6 months and 1, 2 years of surgery, routine outpatient follow-up was conducted to observe and compare the surgical time, bleeding volume, preoperative and postoperative visual analog scale (VAS), knee Lysholm score, and complications between two groups. RESULTS: All incisions healed at one stage after operation. All 54 patients were followed up, and the duration ranged from 6 months to 2 years, with an average of (13.89±4.29) months. There was no intraoperative vascular or nerve injury. Operation time and intraoperative blood loss of the two groups:group A of (62.08±9.55) min and (8.00±1.69) ml, group B of (69.50±6.99) min and (8.70±2.00) ml. Popliteal pain, swelling, limitation of flexion and extension were significantly relieved after operation. VAS before and one month after operation between two groups:group A of 5.38±1.21 and 2.63±0.71, group B of 5.60±1.26 and 2.80±0.81. Lysholm scores of knee joint before and 6 months after operation:group A of 62.59±4.99 and 89.74±2.90, group B of 63.87±3.23 and 89.02±2.35. Knee joint function improved significantly in both groups. In group A, 4 cases had popliteal cyst at 3 months after operation, and 2 cases had small isolated cyst at 1 year after operation. There was no recurrence of cyst in group B. CONCLUSION: The results between two arthroscopic treatments of popliteal cyst are satisfactory, and there is no significant difference in the amount of blood loss, safety, postoperative pain VAS score and knee function recovery. It is suggested that arthroscopic resection of the cyst wall should be performed when the technique is mature, especially for large cysts and septal cysts.

[Locking compression plate combined with medial buttress plate for the treatment of osteoporotic comminuted proximal humerus fractures].

OBJECTIVE: To explore clinical effect of lateral locking compression plate combined with medial buttress plate in treating osteoporotic comminuted fractures of proximal humerus. METHODS: From May 2017 to December 2021, 12 patients with osteoporotic comminution of proximal humerus were treated by lateral locking compression plates combined with medial buttress plates, including 5 males and 7 females, aged from 55 to 78 years old, bone mineral density(BMD) less than -2.5 g/cm3, the time from injury to operation was from 2 to 6 days. According to Neer classification, 7 patients were type Ⅲ, 4 patients were type Ⅳ and 1 patient was type Ⅵ. Postoperative complications, fracture healing and internal fixation were observed and Constant-Murley score of shoulder joint was used to evaluate clinical effects at 6 months after operation. RESULTS: Postoperative wound healed well at stage I. All patients were followed up from 6 to 18 months. Humeral head collapse and necrosis occurred in 1 patient and humeral head varus in 1 patient. No impact of shoulder joint, internal fixation loosening occurred. Constant-Murley score at 6 months ranged from 45 to 90 points, and 6 patients got excellent result, 3 good, and 3 poor. CONCLUSION: Locking compression plate combined with medial buttress plate could effectively reconstruct medial humeral column support and enhance fracture stability, and receive satisfactory clinical results. However, no control group was established in this study, and function of shoulder joint has not been evaluated many times after operation, so it cannot dynamically reflect changes of shoulder joint function.

Diagnosis and Treatment of Intraosseous Ganglion in the Ankle Region.

OBJECTIVE: To investigate the diagnosis and treatment of intraosseous ganglion cyst in the ankle region. METHODS: A retrospective analysis was performed on the diagnosis and treatment of 18 patients with intraosseous ganglion in the ankle region from January 2005 to March 2016. There were 11 males and 7 females, with an average age of 40.4 years (22-74 years). Thirteen of these had mild intermittent localized pain in the ankle and five were asymptomatic and fortuitously found on images. According to the location of the intraosseous ganglion cyst, nine were located in the distal end of tibia, seven were in the distal end of the fibula, and two were in the talus. After curettage of intraosseous ganglion, 15 cases were filled with autogenous iliac bone and 3 cases with artificial bone. RESULTS: Fifteen cases were diagnosed with radiographs and CT scans, two cases with MR images, and one case was confirmed by postoperative pathology. The cyst contents were jelly-like material with sclerotic bone margins. The mean size of the intraosseous ganglion cyst was 1.5 cm × 1.5 cm × 1 cm. Hematoxylin and eosin (H&E) staining of the tissue showed fibrous tissue, collagenous fiber, mucoid, and a few fibroblasts. Eighteen cases were followed up for 11 months to 10 years, with an average of 5.4 years. No recurrence was found. Sixteen patients were asymptomatic after surgery. Two cases of ankle pain occurred at 1 year and 6 months postoperatively, respectively. According to the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot scale, the mean AOFAS ankle-hindfoot score improved from 78.2 ± 13.7 points preoperatively to 97.3 ± 4.5 points at the final follow-up. CONCLUSION: For the intraosseous ganglion cyst in the ankle region, whether there are clinical symptoms or not, the cyst should be curettaged and the cavity should be filled with bone graft. The operation result is satisfactory.

Cepharanthine Ameliorates Chondrocytic Inflammation and Osteoarthritis via Regulating the MAPK/NF-κB-Autophagy Pathway.

Osteoarthritis is a worldwide joint disease caused by abnormal chondrocytic metabolism. However, traditional therapeutic methods aimed at anti-inflammation for early-stage disease are palliative. In the present study, we demonstrated that cepharanthine (CEP), extracted from the plant Stephania cepharantha, exerted protective medicinal efficacy on osteoarthritis for the first time. In our in vitro study, CEP suppressed the elevated expression of matrix metalloproteinases (MMPs), a disintegrin and metalloproteinase with thrombospondin motifs 5 (ADAMTS5) and inducible nitric oxide synthase (iNOS) stimulated by IL-1ß or TNF-α by inhibiting the activation of MAPK and NF-κB signaling pathways, and upregulated the protein expression of aggrecan, collagen II, and Sox9. Also, CEP could reverse the reduced level of cellular autophagy in IL-1ß or TNF-α-induced chondrocytes, indicating that the protective effect of CEP on osteoarthritis was achieved by restoring MAPK/NF-κB-mediated autophagy. Furthermore, in a murine OA model, CEP mitigated cartilage degradation and prevented osteoarthritis in the CEP-treated groups versus the OA group. Hence, our results revealed the therapeutic prospect of CEP for anti-osteoarthritic treatment.

A Nurse's Perspective on Visual Rehabilitation of Outpatients With Low Vision in China.

PURPOSE: The purposes of the study were to analyze patient use and satisfaction with low vision aids (LVAs) at the Wenzhou Medical University Low Vision and Rehabilitation Center and to assess the promotion of visual rehabilitation services as a new responsibility for nurses in China. METHODS: Records of 178 patients with low vision (LV) from the Low Vision and Rehabilitation Center examined between October 2015 and October 2016 included basic patient information (e.g., age, diagnosis, visual acuity, educational level) and use of LVAs (patients' own aids, daily duration of LVA use, or refusal to use aids). RESULTS: Sixty percent owned LVAs. Of these, 66% were obtained from a hospital, 26% were obtained from commercial stores, and others were obtained from government or gifts. Patients reported that use of LVAs was reduced because of visual fatigue (39%), inconvenience (22%), and lack of benefit (12%). Reasons for the 40% who had never used visual rehabilitation were nonreferral by doctors (76%), refusal because of inconvenience, discomfort and cosmetics (20%), or a preference for other treatments (4%). CONCLUSIONS: Greater awareness of LV rehabilitation by nurses, ophthalmologists, patients, and the public is necessary. Additional government support for LV rehabilitation is also required.

The Needs for Visual Improvement of Patients Presented at Low-Vision Center in Wenzhou, China.

PURPOSE: To characterize the needs for visual improvement of new-visit patients with low vision. METHODS: This cross-sectional study collected detailed information of patients presented at low-vision center of the Eye Hospital of Wenzhou Medical University between January 2015 and January 2017. A questionnaire interview, including demographic information and needs for visual improvement, was conducted before ophthalmology examinations. RESULTS: The main need for visual improvement was engagement in hobbies (68.9%), followed by reading (20.9%), engaging in occupation (20.1%), and watching TV or movies (17.1%). Less than 10% of patients mentioned the demand of using public transportation (5.8%), doing housework (3.7%), writing (1.9%), walking on irregular surfaces (1.5%), driving (1.1%), and others (2.4%). Women were significantly associated with a concern for performing hobbies (OR 1.45, 95% CI 1.0-2.0) but associated with lower odds of reading (OR 0.46, 95% CI 0.3-0.7). Older subjects were more willing to choose hobbies (OR 1.35 (per 10-year increase), 95% CI 1.3-1.4), reading (OR 1.11 (per 10-year increase), 95% CI 1.0-1.2), watching TV or movies (OR 1.4 (per 10-year increase), 95% CI 1.3-1.6), and housework (OR 1.21 (per 10-year increase), 95% CI 1.0-1.5) than younger individuals. In comparison with younger participants, older individuals were less likely to choose occupation (OR 0.53 (per 10-year increase), 95% CI 0.5-0.6). No significant association was found between visual acuity and needs for visual improvement. CONCLUSION: Hobbies, reading, engaging in occupation, and watching TV were the most common needs for visual rehabilitation in patients with visual impairment. Gender and age showed a modest influence on the choice of different needs.

[Surgical treatment of tibia plateau fractures with external fixator and the locking plate].

OBJECTIVE: To observe the clinical effect of the treatment for complex fractures of the tibial plateau through the application of the external fixator and the locking plate. METHODS: From Feb. 2006 to Oct. 2008,12 patients with tibial plateau fractures were treated with external fixator and locking plate included 8 males and 4 females with an average age of 38 years ranging from 23 to 59. According to Schatzker type, 7 cases were type V and 5 cases were type VI. Using an anteromedial incision and an anterolateral approach, the locking plate were fixed in the tibia lateral. The collapse and height lossing of tibial plateau was observed through X-ray film before and after operation. The function of knee joint was evaluated according to HSS scoring. RESULTS: These patients were followed up for 4 to 18 months (means 9.79 months). Eleven cases had bone primary union,and 1 delayed union. No deep phlebothrombosis and osteofascial compartment syndrome occurened. The average healing time was 3.1 months. Between the preoperative and postoperative X-ray film there were no second stage depression fracture of the tibial plateau,postoperative reduction loss and bad alignment. The range of knee flexion was 90 degrees to 110 degrees. The HSS knee functional scoring was(75.50 +/- 10.01)scores after operation and (21.50 +/- 11.68) scores before operation. CONCLUSION: The treatment with the external fixator and the locking plate for complex fractures of the tibial plateau could provid continuous stability of fixation,prevent the fracture from second stage displacement and the knee force line change, protect the soft-tissue around the knee, reduce the postoperative complications. The knee joint function is satisfied.
