Objective To evaluate the clinical efficacy of Chevron minimally-invasive osteotomy and internal fixation with ISO intramedullary plate plus traditional Chinese medicine(TCM)bone-setting manipulations for the treatment of moderate hallux valgus.Methods A retrospective study was conducted.A total of 49 patients(62 feet)with moderate hallux valgus were treated with Chevron minimally-invasive osteotomy and internal fixation with ISO intramedullary plate,and were given TCM bone-setting manipulations before the operation,during the operation,and after the operation.The efficacy was evaluated by using the Visual Analogue Scale(VAS)score and the American Orthopedic Foot and Ankle Society(AOFAS)forefoot score after the operation.Before the operation and 12 months after the operation,the hallux valgus angle(HVA),intermetatarsal angle(IMA)between the first and second metatarsal bone,and the distal metatarsal articular angle(DMAA)showed by X-ray imaging in the weight-bearing position of the foot were recorded.Results(1)All of the 49 patients were followed up for 12 to 24 months,with a mean of(20.6±3.1)months.(2)The X-ray imaging assessment showed that 12 months after the operation,the mean HVA,IMA and DMAA values of the 49 patients(62 feet)were significantly lower than those before the operation,and the differences were all statistically significant(P＜0.01).(3)Twelve months after the operation,the pain VAS score of 49 patients was(3.14±1.21)points,which was significantly lower than the preoperative score points(7.26±2.52),and the difference was statistically significant(P＜0.01).(4)The assessment of joint function showed that 12 months after the operation,the scores of various AOFAS items of pain,function and hallux alignment as well as the overall AOFAS scores of 49 patients were significantly higher than those before the operation,and the differences were statistically significant(P＜0.01).(5)For the 62 feet in 49 patients,the excellent efficacy was achieved in 53 feet,good efficacy was achieved in 7 feet,and fair efficacy was achieved in 2 feet,with the fine rate of 96.77%(60/62).Conclusion For the treatment of moderate hallux valgus,the application of Chevron minimally-invasive osteotomy and internal fixation with ISO intramedullary plate plus TCM bone-setting manipulations is effective on promoting the reset of hallux-metatarsophalangeal joint,restoring the balance of the joint,and maintaining the equilibrium state of the joint through postoperative rehabilitation guidance.The combined therapy exerts certain efficacy,reduces the recurrence rate,and eventually achieves the early rehabilitation after the operation.

Objective:To evaluate the efficacy and safety of unilateral adrenalectomy for treating primary bilateral macronodular adrenal hyperplasia (PBMAH) of different clinical types.Methods:The clinical and biochemical data of 54 patients with PBMAH who underwent unilateral adrenalectomy from May 2008 to March 2023 were retrospectively collected. Preoperative CT images of all patients showed enlarged bilateral adrenal glands with multiple nodules of " fused masses". Mean preoperative blood cortisol concentration at 8am was (21.5±7.7)μg/dl, urinary free cortisol concentration was (442.6±300.4)μg/24h, and mean 8am ACTH concentration was (6.4±2.3)pg/ml. Postoperative symptoms, BMI, blood pressure, mass diameter, cortisol and ACTH concentration were recorded and analyzed.Results:Compared with ordinary laparoscopic surgery, robot-assisted surgery showed shorter operation time [(115.4±22.1)min vs.(95.0±19.8)min, P=0.045]; less blood loss [(118.2±57.0)ml vs. (125.6±45.3)ml, P=0.441] and shorter hospitalization time [(5.2±0.9)day vs. (6.4±1.2)day, P=0.279]. Compared with laparoscopic surgery, open surgery showed longer operation time [(134 34.5) min vs. (104.3±20.1) min, P=0.035]; more blood loss [(305.5±85.2) ml vs. (122.5±44.3) ml, P=0.012] and longer hospitalization time[(10.4±3.2)day vs. (5.7±1.0) day, P=0.020]. The average follow-up time was (23.7±11.7) months. Sixteen cases biochemically relapsed, and the average relapse-free time was (25.4±13.4) month. Mean postoperative systolic blood pressure was (131.1±16.8)mmHg ( P=0.001) while diastolic blood pressure decreased to (82.2±11.1)mmHg ( P=0.002). Postsurgical average blood cortisol concentration decreased to (10.2±4.0)μg/dl ( P<0.01), while urine cortisol concentration decreased to (106.6±43.4)μg/24h( P<0.01). Average ACTH concentration increased to (12.6±4.1)pg/ml( P=0.005). Recurrent patients had higher preoperative blood and urine cortisol concentration(24.7±8.2)μg/dl( P=0.046), (522.8±234.2)μg/24h( P=0.028), and all of them underwent contralateral adrenalectomy. Conclusions:Unilateral adrenalectomy is safe and effective for treatment of PBMAH while part of patients biochemically relapsed. Subclinical patients were observed no recurrent cases after surgery. Recurrent patients have higher preoperative blood and urine cortisol levels and should undertake contralateral adrenalectomy and supplement corticosteroids for whole life.

Objective:To investigate the effect of safflower yellow pigment injection combined with alprostadil on patients after coronary artery bypass grafting(CABG).Methods:A total of 92 patients with coronary heart disease who received CABG in Department of Cardiovascular Surgery,Handan Central Hospital between September 2018 and September 2020 were selected.According to order of admission,they were divided into control group(n=46,from September 2018 to Sep-tember 2019,routine therapy+alprostadil after CABG)and study group(n=46,from October 2019 to September 2020,safflower yellow pigment injection based on control group),both groups were treated for 28d.On 3d after drug withdraw-al,therapeutic effect,cardiac function indexes,four myocardial enzyme spectrum and perioperative indexes were compared between two groups.Results:On 3d after drug withdrawal,compared with control group,patients in study group had sig-nificant higher total effective rate(73.9％vs.91.3％),left ventricular ejection fraction(LVEF)[(55.77±4.48)％vs.(62.18±4.21)％](P=0.028,＜0.001),and significant lower left atrial diameter(LAD)[(36.83±3.45)mm vs.(32.09±3.23)mm],left ventricular end-diastolic diameter(LVEDd)[(49.04±4.65)mm vs.(43.83±5.24)mm],levels of creatine kinase(CK)[(125.13±14.21)U/L vs.(62.56±8.42)U/L],lactate dehydrogenase(LDH)[(203.58±31.63)U/L vs.(156.07±22.26)U/L],aspartate aminotransferase(AST)[(44.25±12.98)U/L vs.(35.41±12.37)U/L]and creatine kinase isoenzyme MB(CK-MB)[(28.11±9.84)U/L vs.(17.59±7.41)U/L](P＜0.001 all).Conclusion:The combination of safflower yellow pigment injection and alprostadil can improve the thera-peutic effect and heart function,and reduce myocardial injury in patients after CABG.

OBJECTIVE: To investigate the clinicopathological characteristics and factors influencing the prognosis of non-Hodgkin lymphoma (NHL) in oral and maxillofacial regions. METHODS: Clinicopathological data of 369 patients with oral and maxillofacial NHL initially diagnosed in Peking University Hospital of Stomatology from 2008 to 2020 were collected and analyzed retrospectively. RESULTS: There were 180 males and 189 females. The median age of the patients was 56 years (3 months to 92 years), and the median duration was three months. Clinically, 283 cases manifested as mass, 38 cases as ulcerative necrotizing lesions, and 48 cases as diffuse soft tissue swelling. The lesions of 90 cases located in face and neck (75 cases neck, 20.3%), 99 cases were of major salivary glands (79 cases parotid glands, 20.9%), 103 cases of oral cavity, 50 cases of maxillofacial bones, 20 cases of Waldeyer's ring, and 7 cases of infratemporal fossa. In the study, 247 of the 369 patients had cervical lymphadenopathy, only 40 cases had B symptoms, and 23 cases had the bulky disease. Of the 369 NHLs, 299 (81%) were B-cell NHL, and 70(19%) were T-cell NHL. Diffuse large B-cell lymphoma, extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue, follicular lymphoma, and extranodal natural killer (NK)/T-cell lymphoma nasal type were the most common pathological subtypes. According to Ann Arbor staging, 87, 138, 106, and 38 cases were classified as staged Ⅰ, Ⅱ, Ⅲ, Ⅳ, respectively. The me-dian follow-up time was 48 months, 164 patients died during the follow-up period. The overall survival rates for one year, two years, and five years were 90.1%, 82.4%, and 59.9%, respectively, and the median survival was (86.00±7.98) months. Multivariate analysis showed that age (P < 0.001), Ann Arbor staging (P < 0.001), elevated lactate dehydrogenase (P=0.014), and pathological subtype (P=0.049) were the independent factors influencing the overall survival rate of NHL patients. CONCLUSION Oral and maxillofacial NHL has unique clinical characteristics and distribution patterns of pathological subtypes. Fewer patients had systemic symptoms. Neck and parotid glands were the most common sites invaded by NHL. Advanced age, Ann Arbor stage Ⅲ-Ⅳ, B symptoms, and T-cell NHL may predict a poor prognosis in oral and maxillofacial NHL patients.

To screen and identify the endophytic fungal strains that could promote the accumulation of flavonoids in the callus of Scutellaria baicalensis. Seventeen endophytic fungal strains from S. baicalensis were used to prepare mycelium elicitors and fermentation broth elicitors. Their effects on flavonoid accumulation in S. baicalensis callus were then determined. The results showed that the fermentation broth elicitors of two strains(CL79, CL105) promoted the accumulation of flavonoids. The fermentation broth elicitor of CL79 significantly promoted accumulation of baicalin, wogonoside, baicalein, and wogonin, with the maximum levels increased by 37.8%, 40.4%, 44.7%, and 42.2%(vs. blank), respectively. Similarly, the fermentation broth elicitor of CL105 significantly promoted the accumulation of baicalin, wogonoside, baicalein, and wogonin, with the maximum levels increased by 78.1%, 140.9%, 275.6%, and 208.5%(vs. blank), respectively. CL79 was identified as Alternaria alternata, and CL105 as Fusarium solani. The fermentation broth elicitors of A. alternata CL79 and F. solani CL105 were able to promote the flavonoid accumulation in the callus of S. baicalensis, which enriched the resources of endophytic fungi and provided candidate strains for the development of microbial fertili-zers for improving the quality of S. baicalensis.
