OBJECTIVE: To investigate the effectiveness of Youngswick-Akin osteotomy in the treatment of moderate hallux valgus combined with mild to moderate hallux rigidus. METHODS: The clinical data of 43 patients with moderate hallux valgus combined with mild to moderate hallux rigidus who were admitted between August 2019 and August 2022 and met the selection criteria were retrospectively analyzed. There were 8 males and 35 females. The age ranged from 28 to 77 years, with an average age of 59.0 years. The disease duration ranged from 10 to 35 months, with an average of 20 months. The degree of hallux rigidus included 2 cases of CoughlinⅠ degree, 29 cases of Ⅱ degree, 12 cases of Ⅲ degree. The preoperative hallux valgus angle ranged from 25° to 40°, with an average of 32°. All patients were treated with Youngswick-Akin osteotomy. The first metatarsophalangeal joint space was compared before operation and at 6 months after operation. The American Orthopaedic Foot and Ankle Society (AOFAS) score and visual analogue scale (VAS) score were used to evaluate the functional recovery and pain relief of the patients before operation and at 6 and 24 months after operation. According to the severity of hallux rigidus, the patients were divided into mild group (Ⅰ, Ⅱ degree) and moderate group (Ⅲ degree) to compare the prognosis, including the changes of AOFAS score, VAS score, and the first metatarsophalangeal joint space. RESULTS: The operation time was 60-75 minutes (mean, 65 minutes). The intraoperative blood loss was 10-30 mL (mean, 20 mL). Two cases had superficial infection of the incision margin after operation, and healed well after dressing change and antibiotic treatment. The incisions of the other patients healed by first intention, and no medial cutaneous nerve injury of the great toe occurred. All patients were followed up 24-31 months, with an average of 25.8 months. The patient's hallux valgus deformity was corrected without recurrence; no complication such as osteomyelitis and hallux varus occurred. The AOFAS score, VAS score, and the first metatarsophalangeal joint space after operation significantly improved when compared with those before operation, the AOFAS score and VAS score at 24 months after operation further improved when compared with those at 6 months after operation, and the differences were significant ( P<0.05). The change of VAS score in mild group was significantly better than that in moderate group ( P<0.05); but there was no significant difference in the changes of AOFAS score and the first metatarsophalangeal joint space between the two groups ( P>0.05). CONCLUSION Youngswick-Akin osteotomy for moderate valgus deformity with mild to moderate hallux rigidus can achieve good functional recovery, pain relief, and joint space improvement.

Objective To investigate the effects of transcutaneous electrical nerve stimulation(TENS)combined with mobilization with movement(MWM)on clinical efficacy,musculoskeletal ultrasound findings and bone metabolism indicators in patients with knee osteoarthritis(KOA).Methods Ninety KOA patients were collected and randomly divided into the control group(conventional rehabilitation+TENS,n=45)and the observation group(conventional rehabilitation+TENS+MWM,n=45)using a random number table.Clinical efficacy,knee joint function,musculoskeletal ultrasound indices and bone metabolism indices were compared between the two groups.Results The clinical efficacy of the observation group was superior to that of the control group(P＜0.05).At 2 and 6 months post-treatment,Western Ontario and McMaster Universities Osteoarthritis Index(WOMAC)were significantly lower in the observation group than those of the control group,and Lysholm Knee Scoring Scale scores were higher in the observation group than those of the control group(P＜0.05).Additionally,articular cartilage thickness,bone gla protein(BGP)and bone-specific alkaline phosphatase(BALP)were higher in the observation group than those of the control group,and synovial thickness,suprapatellar effusion and tartrate-resistant acid phosphatase 5b(TRACP-5b)were lower in the observation group than those of the control group(P＜0.05).Conclusion TENS combined with MWM in the treatment of KOA patients can not only improve knee joint function but also optimize musculoskeletal ultrasound indices and regulate bone metabolism indices.

Objective:To investigate the gene expression of pulmonary metastatic papillary thyroid cancer (PTC) and its association with lung metastasis, facilitating risk assessment and personalized therapeutic strategies.Methods:A retrospective cohort study was conducted on 269 PTC patients (61 males, 208 females, age (38.9±11.9) years) treated at the Affiliated Cancer Hospital of Xiangya School of Medicine, Central South University from January 2017 to June 2020, including 60 cases with lung metastasis and 209 without. Primary tumor tissues underwent targeted next-generation sequencing (tNGS). Univariate and multivariate logistic regression analyses were performed to identify risk factors for lung metastasis, and χ2 test was used to evaluate the differences between the effective and ineffective groups of radioactive iodine (RAI) therapy. Results:In 60 PTC patients with lung metastasis, the mutation rates of B-Raf proto-oncogene, serine/threonine protein kinase (BRAF) V600E, telomerase reverse transcriptase (TERT) promoter, and rearranged in transformation (RET) fusion mutations were 28.3%(17/60), 25.0%(15/60), and 26.7%(16/60), respectively. Univariate analysis demonstrated that age≥55 years, multifocality, lateral cervical lymph node metastasis, extrathyroidal extension, BRAF V600E mutation, RET fusion, and TERT promoter mutation were significantly associated with lung metastasis in PTC ( Wald χ2 values: 4.13-31.28, all P<0.05). However, no significant statistical associations were observed between lung metastasis and gender, rat sarcoma type GTPase family (RAS) mutation, tumor protein p53 (TP53) mutation, phosphatidylinositol-4, 5-bisphosphate 3-kinase catalytic subunit alpha (PIK3CA) mutation, neurotrophic tyrosine receptor kinase 1 (NTRK1) fusion, or anaplastic lymphoma kinase (ALK) fusion ( Wald χ2 values: 0.01-3.50, all P>0.05). Multivariate analysis identified TERT promoter mutation (odds ratio ( OR)=11.86, 95% CI: 3.68-38.29, P<0.001), multifocality ( OR=5.30, 95% CI: 2.41-11.69, P<0.001), extrathyroidal extension ( OR=3.98, 95% CI: 1.77-8.98, P=0.001), and lateral cervical lymph node metastasis ( OR=3.13, 95% CI: 1.28-7.68, P=0.013) as independent risk factors for lung metastasis in PTC. Conversely, BRAF V600E mutation emerged as a potential protective factor ( OR=0.09, 95% CI: 0.04-0.21, P<0.001). The proportions of BRAF V600E mutation ( χ2=20.49, P<0.001) and TERT promoter mutation ( χ2=4.91, P=0.027) were higher in the RAI ineffective group. Conclusions:BRAF V600E mutation, TERT promoter mutation and RET fusion are related gene expression in lung metastasis of PTC. Multifocality, extrathyroidal extension, lateral cervical lymph node metastasis and TERT promoter mutation are risk factors for lung metastasis of PTC (TERT is an independent molecular risk marker), while BRAF V600E mutation may be a protective factor. RAI treatment efficacy of PTC patients with lung metastasis and BRAF V600E mutation/TERT promoter mutation is worse.

Objective To observe the effect of buccal needle therapy on perioperative analgesia in patients undergoing laparoscopic radical colon cancer surgery.Methods Sixty patients underwent dective laparoscopic radical of colon cancer surgery were selected,32 males and 28 females,aged 45-74 years,BMI 18.5-25.0 kg/m2 and ASA physical status Ⅱ or Ⅲ.The patients were divided into two groups using the randomized numerical table method:buccal needle group and control group,30 patients in each group.Before the induction of anesthesia,the buccal needle group was given buccal needle therapy once,and buc-cal needle therapy was performed once a day at 9 a.m.in the postoperative period,leaving the needle in place for 30 minutes each time,for 3 consecutive days of treatment,and the control group was not treated with buccal needle therapy.The amount of intraoperative propofol,remifentanil,sufentanil used in the 48 hours postoperative period and recorded.VAS pain scores were recorded at 1 hour,4,24,and 48 hours postoperatively.Venous blood was collected at the time of admission to the hand room and at 1 day,2,and 3 days postoperatively,respectively,and the concentrations of plasma C-reactive protein(CRP),interleu-kin-6(IL-6),and tumor necrosis factor-alpha(TNF-α)were measured.The occurrence of adverse reactions within 48 hours after operation was recorded.Results Compared with the control group,intraop-erative propofol,remifentanil,the amount of sufentanil used and the number of analgesic pump presses with-in 48 hours after operation in the buccal needle group were significantly reduced in the buccal needle group(P＜0.05),VAS pain scores were significantly lower at 1 hour,4,24,and 48 hours postoperatively(P＜0.05),CRP,IL-6,and TNF-α concentrations were significantly lower at 1 day,2,and 3 days postopera-tively(P＜0.05),and nausea and vomiting,incidence of laryngospasm and laryngeal discomfort were sig-nificantly reduced(P＜0.05).Conclusion The perioperative use of buccal needle therapy in patients un-dergoing laparoscopic radical colon cancer surgery can effectively reduce pain,inhibit inflammatory respon-ses,and decrease the incidence of postoperative adverse reactions.

Objective:To explore and evaluate the feasibility and accuracy of using optical coherence tomography and optical coherence microscope (OCT/OCM) for diagnosis of oral cancer.Methods:In this study, OCT/OCM was utilized to image the oral mucosa specimens. A total of 289 ex vivo oral mucosa specimens were collected from 68 patients with oral cancer who were hospitalized at Department of Oral and Maxillofacial Head and Neck Tumors, Capital Medical University School of Stomatology, between January 2021 and February 2023, resulting in a dataset of 1 445 OCT/OCM images. By observing the characteristic patterns in the OCT/OCM images, including normal oral mucosa, epithelial abnormal proliferation (mild, moderate, severe), and oral cancer, these patterns were matched with corresponding pathological images. A diagnostic study was conducted, employing pathological diagnosis as the gold standard and utilizing a double-blind experimental design involving three diagnostic evaluators who participated in the analysis and diagnosis of OCT/OCM images. Results:The OCT/OCM images demonstrated good correlation with the corresponding pathological images, and diagnostic criteria were established based on the comparative results. In the diagnostic study involving three investigators, the accuracy was 82%, sensitivity was 84% (95% CI: 80%-88%), and specificity was 81% (95% CI: 77%-85%). There was a high level of agreement among the observers (kappa=0.614), indicating substantial concordance in the diagnostic results among the three investigators. Conclusions:This study demonstrates the potential of OCT/OCM for diagnosis of oral cancer. The technology accurately distinguishes between normal oral mucosa, epithelial abnormal proliferation and oral cancer.

Objective To compare the effect of palliative mitral valve surgeries and medication therapies for secondary non-ischemic mitral regurgitation. Methods The clinical data of patients with non-ischemic functional mitral regurgitation treated in our hospital between 2009 and 2019 were retrospectively analyzed. Patients with a left ventricular ejection fraction (LVEF)＜40% underwent a dobutamine stress test, and a positive result was determined when the LVEF improved by more than 15% compared to the baseline value. Positive patients were divided into a surgery group and a medication group. The surgery group underwent surgical mitral valve repair or replacement, while the medication group received simple medication treatment. Follow-up on survival and cardiac function status through outpatient or telephone visits every six months after surgery, and patients underwent cardiac ultrasound examination one year after surgery. The main research endpoint was a composite endpoint of all-cause death, heart failure readmission, and heart transplantation, and the differences in cardiac function and cardiac ultrasound parameters between the two groups were compared. Results Ultimately 41 patients were collected, including 28 males and 13 females with an average age of 55.5±11.1 years. Twenty-five patients were in the surgery group and sixteen patients in the medication group. The median follow-up time was 16 months, ranging 1-96 months. The occurrence of all-cause death in the surgery group was lower than that in the medication group (HR=0.124, 95%CI 0.024-0.641, P=0.034). The difference between the two groups was not statistically significant in the composite endpoint (HR=0.499, 95%CI 0.523-1.631, P=0.229). The New York Heart Association (NYHA) grade of the surgery group was better (NYHA Ⅰ-Ⅱ accounted for 68.0% in the surgury group and 18.8% in the medication group, P<0.01) as well as the grade of mitral valve regurgitation (87.5% of the patients in the medication group had moderate or above regurgitation at follow-up, while all the patients in the surgery group had moderate below regurgitation, P<0.01). There was no statistical difference in preoperative and follow-up changes in echocardiograph parameters between the two groups (P＞0.05). Conclusion For non-ischemic functional mitral regurgitation, if the cardiac systolic function is well reserved, mitral valve surgery can improve survival and quality of life compare to simple medication therapy.

Objective:To analyze the construction and operation of the 19th Hangzhou Asian Games designated hospitals, and to discuss the medical emergency security work of large-scale sports events, so as to provide references for the planning of designated hospitals in future large-scale sports events.Methods:Retrospective analysis was made on the establishment principles, requirements, selection of medical support personnel, and training exercises of the designated hospitals, focusing on the key links such as organizational system, staffing, designated areas, and drug management.Results:Total of 40 designated hospitals have successfully completed the task of medical security by rebuilding the medical security area of the Asian Games, elevating the process, equipping facilities, and strengthening staff training. During the Asian Games, 349 people were transferred to designated hospitals by ambulance, 54 people were hospitalized, 19 people underwent surgery, and 1022 people went to designated hospitals by themselves.Conclusion:The construction of the designated hospitals during the 19th Hangzhou Asian Games was of high quality, efficient and smooth operation. It is suggested that efforts should be made in the reconstruction of the medical security area for the Asian Games to be "relatively independent". The treatment process of self-visiting patients should be fully considered and the flat urgent emergency response mechanism needs to be established.
