Objective To analyze the ultra microstructure and histological properties of implanted composites of decalcified bone matrix (DBM) impregnated calcium phosphate cement (CPC) with recombinant human bone morphogenetic protein-2 (rhBMP-2) in bone defect, and evaluate the osteoplastic efficiency of this composites. Methods The rabbit DBM was prepared beforehand. The composites of DBM impregnated CPC with rhBMP-2 was made at 0.2 proportion of DBM. The rabbit's bone defect of femur condyle was filled with implantation of the composites (group A, n=12) or CPC (group B, n=12) or bone cement (group C, n=12). Animals were sacrificed at 6, 12, or 24 weeks after operation, and the implants were examined by histological technique and scanning electron microscopy (SEM). Results In group A, at the 6th week after operation, the interface region between implants and bone tissue became fuzziness, and was crossed by the generated fibers of bone tissue, and filled with woven bone growing inside into the composites; at the 12th week after operation, blood vessels, osteoblasts and new bone were generated inside of composites; at the 24th week after operation, the bone defects were recovered and became solid union, most of the implants were replaced by new bones. In group B, at the 6th week after operation, the interface of CPC and bone tissue was sharp, and was not crossed by new bones; at the 24th week after operation, the bone defects were still filled with materials of CPC and no new bone was found inside CPC. In group C, at the 24th week after operation, the interface of bone cement and bone remained non-union. Higher osteoblastic activity,more neogenetic blood vessels and higher growth rate of woven bone were observed in group A compared with those in group B. Conclusions For bone defect, the implantation of composites with DBM proportion of 0.2 can stimulate the growth of osteoblast, blood vessel and woven bone. It is biodegradable and can be replaced by autogenous bone.

OBJECTIVETo evaluate the prevalence of primary gout in the Shantou area, China, and to understand its clinical features.
METHODSSamples from three surveys of the Chenghai across ten years were studied. Clinical, laboratory and radiology data of 419 cases of primary gout were collected and analyzed.
RESULTSPrevalence of primary gout in the three surveys were 0.17%, 0.15% and 0.26%, respectively. Among the clinical patients, the ratio of male to female was 21:1; the average age of onset of women was significantly higher than that of men. The number of cases in the last ten years has been increasing. In the first wave of cases, the first metatarsophalangeal joint was involved in 82.1% of all cases; no fourth metatarsophalangeal joint involvement had been observed. Hyperlipemia was the most common accompanying abnormal laboratory test (57.1%). Radiographic bone erosion was found in 49.4% patients, most of them with disease duration more than 5 years.
CONCLUSIONSThe prevalence of primary gout in Shantou area has been increasing in the last ten years. Changes in diet and lifestyle may be responsible for this rapid increase.

Objective:To investigate the safety and efficacy of pseudomonas aeruginosa Injection (PAI) in the treatment of coeliac leakage after cervical lymph node dissection for robotic thyroid cancer.Methods:Retrospective analysis of 1262 patients who underwent robotic thyroid surgery at the 960th Hospital of the People’s Liberation Army from Jan. 2021 to Aug. 2023 was made. Postoperative celiac leakage happened in 28 patients. The control and injection groups were divided according to whether pseudomonas aeruginosa injection was used or not. In the control group, there were 4 males and 11 females out of 15 patients, with an average age of (46.20±9.02) years old, and the treatment methods of low-fat diet, negative pressure suction, and pressure bandage were used. In the injection group, there were 7 males and 6 females among 13 patients, with an average age of (41.00±8.87) years. They were treated with low-fat diet, negative pressure suction, pressure bandage, and PAI .The number of lymph node dissection, total drainage volume, peak drainage volume, days of hospitalization and the rate of decline in drainage volume within 24 h after the use of PAI in the injection group, post-injection temperature, number of injections, and post-injection extubation time were statistically analyzed in both groups. Independent samples t test, Mann-Whitney U test, χ2 test or Fisher’s exact test were used for comparison between groups. Results:There was no statistically significant difference in age, gender, extent of thyroidectomy, highest daily drainage volume, and total drainage volume between the two groups ( P>0.05). The difference in the number of lymph node dissection (49.15±23.05 vs. 30.80±11.76, P=0.012) and hospitalization time (11.77±4.64 vs. 16.40±6.42, P=0.041) between the injection group and the control group was statistically significant. After the use of pseudomonas aeruginosa injection, the draining fluid decreased from the previous day (69.56± 20.82) % in the injection group; Twelve patients were successfully extubated after one injection of pseudomonas aeruginosa injection, and one patient was successfully extubated after two injections; the mean time to extubation after injection was (3.85±1.28) days; 76.9% patients (10/13) had fever symptoms within 48 h with body temperature (38.05±0.89) ℃ after injection, body temperature returned to normal after symptomatic treatment,and no other adverse reactions occurred except fever. Conclusion:Pseudomonas aeruginosa injection is safe and effective in the treatment of celiac leakage after cervical lymph node dissection for robotic thyroid cancer, effectively reducing cervical drainage and shortening hospitalization days.
