BACKGROUND:Morinda has been reported to promote the proliferation, the secretion of alkaline phosphatase and osteocalcin, and mRNA expression of transforming growth factor of osteoblasts. However, little information is available addressing the effects of Morinda on receptor activator of nuclear factor-κB expression in osteoclasts in rats with osteoporosis. OBJECTIVE:To study the effects of Morinda on receptor activator of nuclear factor-κB expression in osteoclastsofosteoporosis rats. METHODS:Thirty Sprague-Dawley rats were equaly and randomly divided into Morinda and 17β-estradiol groups. Rat models of osteoporosis were established by bilateral ovariectomy, and then 5 mL of Morinda decocta(1.0mmol/L)and 17β-estradiol (1×10-6mmol/L) were administered intragastricaly to rats in Morinda and 17β-estradiol groups for 3 consecutive months, respectively. Primary osteoclasts were isolated from rats in both groups, andthen cultured for 3, 6 and 9 days folowed by TRAP staining andcelcounting. Bone mineral density of the proximal and distal femur, urine and serum levels of Ca2+and progesterone, and receptor activator of nuclear factor-κB expression in osteoclasts ofrats in both groups were determined. RESULTS AND CONCLUSION:Osteoclast fusion was reduced in Morinda group. In contrast, number of osteoclastswas increased andcels becamemore maturein the17β-estradiol group. Bone mineral density of the proximal and distal femur bilateraly, urine and serum levels of Ca2+and progesterone were significantly increased, while receptor activator of nuclear factor-κB expression was significantly decreased in osteoclasts in Morinda group compared with 17β-estradiol group (P< 0.05). These results indicate that Morinda reduces receptor activator of nuclear factor-κB expression in osteoclasts in osteoporosis rats, thereby inhibiting the development and progression of osteoporosis.

Objective To explore the integration of the digital imaging medical records system and the hospital information system ( HIS), for a hospital-wide information platform for digital medical records management. Methods All the medical records were classified as " to copy and not to copy" by sampling, and an item corresponding table was developed for both HIS medical record files and imaging records copying types. The imaging copying system for paper-based medical records only covers those must-copy ones, while those medical record files without need to be copied were directly transcoded via the interface to the imaging medical records system from the HIS system. This makes digital imaging medical records complete. Results The digital imaging medical record system is thus integrated, and the cost of making imaging medical records was sizably reduced without compromising the quality and integrity of medical records. Conclusions Imaging medical records produced by copying paper-based ones are integrated with those directly sent via the interface to the imaging medical records system, forming complete digital imaging records, at a much lower cost.

ObjectiveTo observe the architectural parameter changes of the muscles around the knee in middle-aged and elderly women with early knee osteoarthritis (KOA) by musculoskeletal ultrasound, and to clarify the indicators of muscles that affect early KOA. MethodsFrom January to August, 2022, 20 healthy middle-aged and elderly healthy women (controls) and 20 middle-aged and elderly women with unilateral early KOA (KOA group) were recruited through Beijing Bo'ai Hospital, to measure muscle thickness of the popliteus muscle, the muscle thickness and the pennation angle of the quadriceps, as rectus femoris, vastus intermedius, vastus lateralis, vastus medialis longus and vastus medialis oblique. ResultsCompared with the healthy limb of KOA group, and the controls, the muscle thickness of vastus medialis longus, vastus medialis oblique and popliteus muscle of the affected limb of KOA group became thinner (t > 2.133, P < 0.05); the proportion of thickness of vastus medialis oblique to thickness of vastus lateralis became smaller (t > 3.660, P < 0.05). The pennation angle was smaller in the affected limb of KOA group than in the matched dominant side of the controls (t = 3.101, P < 0.05). Logistic regression analysis showed that the muscle thickness of vastus medialis oblique (OR = 0.235, 95%CI 0.068 to 0.805, P = 0.021) and popliteus muscle (OR = 0.387, 95%CI 0.152 to 0.980, P = 0.045) were related to the onset of early KOA. ConclusionThe thickness of vastus medialis longus, vastus medialis oblique and popliteus muscle decrease, and the balance of the strength of vastus medialis oblique and vastus lateralis weakens in the affected limbs of the middle-aged and elderly women with early KOA. The thickness of vastus medialis oblique and popliteus muscle are protective factors for onset of KOA.

OBJECTIVETo investigate the clinical features, diagnostic and therapeutic strategy of primary intraspinal melanocytoma.
METHODThe clinical data of primary intraspinal melanocytoma patients who underwent surgical operations from June 2011 to December 2014 in Department of Neurosurgery, Beijing Tiantan Hospital, Capital Medical University were retrospectively reviewed.
RESULTSSix cases of intraspinal melanocytoma, identified with pathology were collected, including 5 male and 1 female patients with the average age of 39.8 years (range 23-50 years). Limbs anesthesia and weakness were present in 2 cases. Neck and back pain were present in 4 cases. All patients performed MRI examination before operation, and only 1 case was diagnosed as primary melanocytoma, and the others were confirmed by postoperative pathology. All cases were confirmed by the pathological examination. Total resection was achieved in 2 cases, subtotal resection was achieved in 2 cases, 2 disseminated cases only achieved partial resection. The average period of postoperative follow-up process was 25.7 months(range 9-52 months). One case recurred in 9 months after surgery and died in 16 months, one case recurred in 1 year after surgery, and the other 4 cases had no recurrence. The recurrenced 2 patients had been not treated with radiotherapy, 2 patients of the 4 that not recurrenced had received radiotherapy. All patients didn't receive chemotherapy. The other patients were in good condition after surgery.
CONCLUSIONSThe intraspinal primary melanocytoma is less likely to recurrence and metastasis if total resection is achieved. Diagnosis relies on pathology. Surgery is the first choice and early total resection is strongly recommend. Appropriate radiotherapy for partial resection cases can delay tumor recurrence.
