Objective : To explore the prognostic value of chemoradiotherapy based on the depth of invasion (DOI) in patients with oral squamous cell carcinoma. Methods : Patients with oral squamous cell carcinoma who received surgical treatment in a hospital from 2008 to 2016 were enrolled. The chi-square test was used to compare the effects of DOI on postoperative cervical lymph node metastasis and local recurrence. The effects of chemoradiotherapy on postoperative cervical lymph node metastasis, local recurrence, and survival were analyzed based on the DOI. Results: A total of 111 patients with oral squamous cell carcinoma were included in this study. The postoperative local recurrence rate (P<0.05) and cervical lymph node metastasis rate (P<0.05) of patients with 5 mm < DOI ≤ 10 mm and DOI > 10 mm were significantly higher than those with DOI ≤ 5 mm. The time of postoperative recurrence was concentrated within two years after the operation. The greater the DOI was, the shorter the time to postoperative recurrence (P<0.05). The addition of postoperative chemoradiotherapy did not significantly improve the postoperative local recurrence rate, cervical lymph node metastasis or survival rate of patients with different DOIs (P > 0.05). Conclusion DOI has important predictive value for postoperative recurrence, cervical lymph node metastasis and survival rate. However, DOI cannot be used as an independent index to guide whether chemoradiotherapy is needed after oral cancer surgery.

High quality is the premise for the implementation of high quality and good price for decoction pieces， and grade is the most direct manifestation of high quality of decoction pieces. However， there is still a lack of scientific and reasonable methods for evaluating the grade of decoction pieces， and it is urgent to establish a widely recognized and unified standard for the grade of decoction pieces to ensure the quality of the decoction pieces and guarantee the safety and efficacy of clinical use. Based on this， this paper focused on analyzing the problems of the current grade evaluation methods， such as unclear distinction between quality standards and grade standards， unreasonable selection of grade evaluation indicators， and inaccurate application of mathematical statistical methods. Based on the analysis of the grade evaluation of decoction pieces， this paper proposed four criteria for establishing the grade evaluation method of decoction pieces， namely universality， comprehensiveness， reliability and convenience， in order to establish a more reasonable and unified grade standard for decoction pieces and promote the quality improvement of decoction pieces and the development of the industry.

Diabetic kidney disease is one of the complications of diabetes,which can progress to end-stage renal disease.In recent years,it has been found that miRNAs have become a research hotspot,with miRNA-21 regulating transforming growth factor β1(TGF-β1)/Smads,phosphoinositide 3-kinase(PI3K)/protein kinase B(AKT),Wnt/β-catenin and other signaling pathways to promote the progress of diabetic kidney disease.Studies have showed that traditional Chinese medicine has a regulatory effect on the expression of miRNA-21 and can target miRNA-21 to regulate TGF-β1/Smads,phosphatase and tensin homolog/PI3K/AKT/mammalian target of rapamycin(mTOR),peroxisome proliferator activated receptors and other signal transduction pathways to trigger signal cascade reactions,which intervene in pathological processes such as fibrosis,inflammation,oxidative stress and autophagy.In this article,the role of miRNA-21 in diabetic kidney disease and the intervention of traditional Chinese medicine were summarized,in order to provide some reference for the treatment of diabetic kidney disease and the development of new drugs.

During coronavirus disease 2019 epidemic, the treatment of severe trauma has been impacted. The Consensus on emergency surgery and infection prevention and control for severe trauma patients with 2019 novel corona virus pneumonia was published online on February 12, 2020, providing a strong guidance for the emergency treatment of severe trauma and the self-protection of medical staffs in the early stage of the epidemic. With the Joint Prevention and Control Mechanism of the State Council renaming "novel coronavirus pneumonia" to "novel coronavirus infection" and the infection being managed with measures against class B infectious diseases since January 8, 2023, the consensus published in 2020 is no longer applicable to the emergency treatment of severe trauma in the new stage of epidemic prevention and control. In this context, led by the Chinese Traumatology Association, Chinese Trauma Surgeon Association, Trauma Medicine Branch of Chinese International Exchange and Promotive Association for Medical and Health Care, and Editorial Board of Chinese Journal of Traumatology, the Chinese expert consensus on emergency surgery for severe trauma and infection prevention during coronavirus disease 2019 epidemic ( version 2023) is formulated to ensure the effectiveness and safety in the treatment of severe trauma in the new stage. Based on the policy of the Joint Prevention and Control Mechanism of the State Council and by using evidence-based medical evidence as well as Delphi expert consultation and voting, 16 recommendations are put forward from the four aspects of the related definitions, infection prevention, preoperative assessment and preparation, emergency operation and postoperative management, hoping to provide a reference for severe trauma care in the new stage of the epidemic prevention and control.

Objective:To evaluate the clinical effects of anatomical reconstruction of the deltoid ligament and medial migration calcaneal osteotomy in the treatment of chronic ankle instability after trauma.Methods:A retrospective study was conducted to analyze of the clinical data of 16 patients with chronic post-traumatic instability of the medial malleolus who had been treated at The Eighth Department of Orthopedics, Foshan Hospital of Traditional Chinese Medicine from December 2015 to February 2017. There were 14 males and 2 females with an age of (28.1±4.2) years. Seven left sides and 9 right sides were affected; the time from injury to operation was (8.9±2.4) months. Before operation, X-rays (anteroposterior, lateral and Saltzman views) and MRI of weight-bearing ankle were taken. All patients were treated by anatomical reconstruction of the deltoid ligament using the autologous semitendinosus and medial migration osteotomy of the calcaneus. The time for injury healing and occurrence of complications were recorded. The talus tilt angle, Meary angle, hindfoot valgus angle, visual analogue scale (VAS), and the American Orthopedic Foot & Ankle Society (AOFAS) ankle-hindfoot function score were compared between the preoperation and the last follow-up. The Sefton evaluation for efficacy in ankle ligament reconstruction was used to assess stability of the ankle joint.Results:Of this cohort, 14 patients were followed up for (16.4±4.9) months after operation and 2 patients lost to follow-up. The 14 patients all returned to normal physical activities 3 months after operation. All incisions healed at the first stage with no infection. One patient experienced pain at the site for harvest of the semitendinosus but the symptoms were relieved after rehabilitation treatment like massage and physical therapy. At the last follow-up, the talus tilt angle [1.0 (0.0, 2.0)°], Meary angle (1.4°±4.2°), hindfoot valgus angle (3.2°±2.4°), VAS score [0.5 (0.0, 1.0) points], and AOFAS ankle-hindfoot score [(89.2±6.1) points] were all significantly improved compared with the preoperative values [8.3°±1.8°, 0.8°±3.8°, 9.9°±3.4°, (5.7±2.5) points, and (49.6±9.8) points] (all P<0.05). According to the Sefton evaluation, the stability of the ankle joint was excellent in 9 cases, good in 4 cases, and fair in 1 case. Conclusion:In the treatment of chronic ankle instability after trauma, anatomical reconstruction of the deltoid ligament and medial migration calcaneal osteotomy is safe and effective, resulting in limited complications.

Pulmonary blast injury has become the main type of trauma in modern warfare, characterized by externally mild injuries but internally severe injuries, rapid disease progression, and a high rate of early death. The injury is complicated in clinical practice, often with multiple and compound injuries. Currently, there is a lack of effective protective materials, accurate injury detection instrument and portable monitoring and transportation equipment, standardized clinical treatment guidelines in various medical centers, and evidence-based guidelines at home and abroad, resulting in a high mortality in clinlcal practice. Therefore, the Trauma Branch of Chinese Medical Association and the Editorial Committee of Chinese Journal of Trauma organized military and civilian experts in related fields such as thoracic surgery and traumatic surgery to jointly develop the Clinical treatment guideline for pulmonary blast injury ( version 2023) by combining evidence for effectiveness and clinical first-line treatment experience. This guideline provided 16 recommended opinions surrounding definition, characteristics, pre-hospital diagnosis and treatment, and in-hospital treatment of pulmonary blast injury, hoping to provide a basis for the clinical treatment in hospitals at different levels.

Objective:To evaluate three-stage induced membrane technique combined with anterior and posterior double-plate fixation in the treatment of a total talus defect after infection.Methods:Included in this study were 11 patients with talus infection who had been treated at Department of Orthopaedics, Foshan Hospital of Traditional Chinese Medicine from January 2014 to December 2018. They were 8 males and 3 females, aged from 23 to 63 years (mean, 37.0 years). The infection followed re-implantation after open dislocation of total talus in 4 cases, internal fixation for open talus fracture of Gustilo type Ⅲa in 3 cases and surgery of open ankle fracture of Gustilo type Ⅲc in 2 cases, and was complicated with ankle intraarticular tuberculosis in 2 cases. The three-stage operations consisted of debridement, total talus resection, implantation of antibiotic bone cement and vacuum sealing drainage at the first stage, change of bone cement, re-debridement, wound closure or flap covering at the second stage 7 to 10 days later, and reconstruction after infection control using anterior and posterior double-plate fixation and induced membrane technique at the third stage 6 to 12 weeks later. Assessment of lower limb shortening was performed by comparing the full length of the leg between the normal and affected sides; the functions were assessed by comparing the ankle-hindfoot scores of American Orthopedic Foot and Ankle Society (AOFAS) and visual analogue scale (VAS) between preoperation and the final follow-up.Results:The 11 patients were followed up for an average of 24.3 months (from 12.2 to 37.5 months). Superficial skin necrosis was observed in 2 patients and injury to superficial peroneal nerve in one. Absolute calcification of the autograft area was observed in all patients, leading to ankle fusion. The final follow-ups observed no significant difference in the full length of the leg between the normal and affected sides [(380.4±35.5) mm versus (376.3±32.8) mm] ( P>0.05) , a significant increase in the ankle-hindfoot AOFAS scores from preoperative 28.0±3.4 to 72.8±5.4, and a significant decrease in VAS scores from preoperative 5(5,6) to 0(0,1) (all P<0.05). Slight varus developed in 2 patients and slight ankle stiffness in 3; recurrence of infection or breakage of implants was found in none of the patients. Conclusion:Three-stage induced membrane technique combined with anterior and posterior double-plate fixation can effectively control infection of the talus, maintain the length and reconstruct the function of the lower limb after a total talus defect.

Objective:To study the efficacy of minimally PCWO combined with Akin osteotomy on severe hallux valgus.Methods:This retrospective study was conducted on 45 patients (50 feet) with severe hallux valgus treated by minimally PCWO combined with Akin osteotomy in Eight Department of Bone, Foshan Hospital of traditional Chinese Medicine from August 2016 to August 2018. HVA, IMA, DMAA, DASA, IPA were measured by X-ray examination preoperatively and after operative 3, 6, 12 months and at the final follow-up. The efficacy was evaluated in accordance with the American Orthopaedic Foot and Ankle Association (AOFAS) Ankle Hindfoot Scale and the Olerud-Molander Ankle (OMA) Score. The absolute and relative lengths of the first metatarsus were measured by X-ray examination preoperatively and at the last follow-up, with calculating the differences.Result:All patients were followed up within 18.20±2.04 months. There was no recurrence during follow-up period. HVA was 42.83°±4.63°, 12.83°±1.53°, 13.49°±1.33°, 14.08°±1.49° and 14.12°±1.35° at the preoperative, postoperative 3 months, 6 months, 12 months and the last follow-up, respectively, and the difference between pre-operation and post-operation was statistically significant ( P<0.05). IMA was 18.29°±0.94°, 7.84°±1.22°, 8.31°±1.03°, 9.01°±1.08° and 9.09°±1.11° at the preoperative, postoperative 3 months, 6 months, 12 months and the last follow-up, respectively, and the difference between pre-operation and post-operation was statistically significant ( P<0.05). AOFAS scores were 50.64±7.94, 88.80±2.68, 90.10±3.51, 91.20±3.89 and 91.37±3.71 points at the preoperative, postoperative 3 months, 6 months, 12 months and the last follow-up, respectively, and the difference between pre-operation and post-operation was statistically significant ( P<0.05). The OMA scores were 61.00±7.00, 90.90±5.02, 91.60±4.57, 93.20±3.61 and 93.48±4.91 at preoperative, postoperative 3 months, 6 months, 12 months and the last follow-up, respectively, and the difference between pre-operation and post-operation was statistically significant ( P<0.05). The absolute shortening of the first metatarsal was 3.03 mm and relative shortening was 0.72 mm. Conclusion:For severe hallux valgus, minimally PCWO combined with Akin osteotomy can effectively correct the hallux valgus deformity with small surgical incision, high safety and curative effect, which is worthy of popularization and application in clinical.
