Objective:To investigate the clinical efficacy of the modified superior gluteal artery perforator (SGAP) flap V-Y advancement technique in the repair of sacrococcygeal pilonidal sinus.Methods:A retrospective analysis was conducted on the clinical data of patients who underwent modified SGAP flap V-Y advancement for the reconstruction of sacrococcygeal pilonidal sinus wounds at the Department of Burns and Plastic Surgery, Affiliated Hospital of Zunyi Medical University, between January 2019 and January 2025. The surgical procedure involved two stages. During the first stage, the sinus tract was preoperatively marked with methylene blue, followed by complete excision of the sinus and surrounding involved tissues. The resultant wound was then treated with vacuum sealing drainage for 3 to 5 days. The second stage consisted of flap repair. A portable Doppler ultrasound was used to identify and mark the superior gluteal artery perforator on one side of the wound. A V-shaped flap was designed transversely, with the base corresponding to the length of the subcutaneous tissue defect on the wound side and the superior and inferior borders extending laterally along the wound margins, ensuring the 1-2 SGAP was included within the flap. Intraoperatively, the wound was re-debrided. The epidermis was removed from the base of the V-shaped flap, and the dermis and subcutaneous tissue were dissected. The dermis and superficial subcutaneous tissue of the contralateral wound edge were also dissected. The flap was then advanced in a V-Y fashion to cover the wound. The de-epithelialized portion of the flap was imbricated and sutured to the contralateral skin edge near the midline. The donor site at the apex of the V-shaped flap was closed directly after subcutaneous tissue tension relief, resulting in a Y-shaped closure. Postoperative flap survival, incision healing, and complications were observed. At the final follow-up, flap appearance, texture, surgical site scarring, and sinus recurrence were assessed, and patient satisfaction with the surgical outcome was investigated.Results:A total of eight patients were included in the study, comprising six males and two females, with ages ranging from 14 to 41 years (mean 22.4 years). Two patients presented with multiple sinus tracts, two with chronic sinus tracts and recurrent inflammation with scar formation, and four with postoperative recurrence. The area of the wound defect after debridement ranged from 4.5 cm×5.0 cm to 6.5 cm×8.0 cm. The flap dimensions ranged from 4.5 cm × 6.0 cm to 6.5 cm × 12.5 cm, with a mean V-shaped flap apex angle of 35° ± 2° (range 20° to 60°). In one patient, slight exudate was observed at the base of the flap, which healed after 12 days of dressing changes and drainage. The remaining flaps survived successfully, and primary closure was achieved in both the donor and recipient sites. The patients were followed for a period of 3 to 64 months, with a mean follow-up duration of 10.7 months. In all patients, the sacrococcygeal flap showed no evidence of bulkiness, exhibiting a color similar to the surrounding skin and a soft texture. Linear scars remained at the surgical site, with no complaints of itching, pain, or other discomfort affecting daily life. No recurrence of pilonidal sinus was observed during the follow-up period. Patients reported satisfaction with the appearance of their buttocks.Conclusion:The modified SGAP flap V-Y advancement technique for the repair of sacrococcygeal pilonidal sinus effectively elevates the gluteal cleft, facilitates off-midline closure, demonstrates reliable result, and provides a high level of patient satisfaction.

Objective:To evaluate the role of a single PET-CT scan in predicting survival and prognosis in patients with non-small cell lung cancer (NSCLC) who did not undergo surgery but received radiotherapy after neoadjuvant chemotherapy combined with immunotherapy.Methods:A retrospective analysis was conducted on the data of 23 NSCLC patients treated at the Cancer Hospital of the Chinese Academy of Medical Sciences from May 2022 to June 2024. All patients were pathologically confirmed, received neoadjuvant chemotherapy combined with immunotherapy, did not undergo surgery for various reasons, and instead received radiotherapy. Each patient underwent only one PET-CT scan after neoadjuvant chemotherapy combined with immunotherapy and before radiotherapy. According to the maximum standardized uptake value (SUV max) on PET-CT, patients were divided into the low-uptake group (SUV max < 8, n=12) and high-uptake group (SUV max ≥ 8, n=11). Survival analysis was performed using the Kaplan-Meier method with survival curves plotted. Univariate analysis of influencing factors of survival was conducted using the Cox proportional hazards regression model. Clinical characteristics and survival outcomes of the two groups were compared, including progression-free survival (PFS) and overall survival (OS). Results:The 1-year PFS rates were 100% in the low-uptake group, 54.5% in the high-uptake group. This difference was statistically significant ( P=0.007). The 1-year and 2-year OS rates were both 100% in the low-uptake group, the 1-year and 2-year OS rates were both 90.9% in the high-uptake group, with no statistically significant difference ( P=0.394). Univariate Cox analysis identified age as an independent factor affecting PFS. Conclusions:For NSCLC patients who did not undergo surgical resection but received radiotherapy after neoadjuvant chemotherapy combined with immunotherapy, a single PET-CT scan before radiotherapy has potential value in predicting PFS. However, clinical studies with larger sample size and longer follow-up are required to evaluate its predictive value for OS.

The objective of this study was to evaluate the toxicity and safety of novel Mycobacterium tuberculosis fusion strain protein derivatives,referred to as B/R strain active proteins.In cellular experiments,RAW264.7 cells were treated with each vaccine preparation,and apoptosis rates were measured.In subsequent animal experiments,C57BL/6 mice were immunized via subcutaneous injection,and their survival and body weight changes were monitored and recorded at 2,4,8,12,and 16 weeks.The lungs and spleens were harvested to calculate organ coefficients,and pathological examinations were conducted.At the eighth week of immunization,the mice were infected with high concentrations of BCG,and pathological changes in the lungs and spleens were observed 4 weeks post-infection.The apoptosis rate at 6 hours was significantly higher in the experimental group than the PBS group(P<0.05).At 12 and 24 hours,the apoptosis rate in the experimental group remained higher than that in the PBS group,although this difference was not statistically significant.After immunization,mice in all four groups exhibited normal growth patterns,as indicated by stable body weight changes.At 4 and 12 weeks post-immunization,the lung coefficients in the protein group were significantly higher than those in the PBS group at the same time points.Additionally,the lung coefficients in the BCG group were significantly elevated across all time periods(P<0.05).The spleen coefficients in the protein and BCG groups were significantly higher than those in the PBS group at 2,4,8,12,and 16 weeks,whereas the ICD B/R group showed higher spleen coefficients than the PBS group only at week 8(P<0.05).Pathological examination revealed normal lung and spleen tissues in the PBS group.However,during the 2-8 weeks immunization period,lung and spleen tissues in all experimental groups exhibited varying degrees of damage,which gradually diminished by 12-16 weeks.Notably,no tuberculosis nodules were observed in any experimental group.After infection with high concentrations of BCG,no overt pathological changes were observed on the surfaces of the lungs and spleens in any group.Microscopic examination revealed less severe pathological changes in the lungs and spleens of mice in the experimental groups than the PBS group.Furthermore,no statistically significant differences were observed between the protein group and the BCG group.Our findings suggested that the B/R strain active proteins'toxicity and safety profiles were comparable to those of BCG,and showed immunoprotective effects.This study provides an experimental foundation for the development of a novel tuberculosis vaccine.

Objective:To investigate the clinical effect of chimeric flap with perforating branch of superficial circumflex iliac artery in reconstruction of complex tissue defect in Achilles tendon region.Methods:A retrospective analysis was conducted on 9 patients who underwent reconstruction of composite tissue defects in Achilles tendon region with the perforator flap of lateral femoral circumflex artery, from January 2017 to January 2023 in the Department of Burns and Plastic Surgery, Affiliated Hospital of Zunyi Medical University. The patients were 7 males and 2 females and at 16 to 54 years, with 36.6 years in average. Causes of injury were: 5 patients by traffic accident, 2 by machine strangulation and 1 by heavy object, also 1 defect was caused by infection. The soft tissue defects were 4.5 cm×6.0 cm to 8.0 cm×12.0 cm in size, and the defects of Achilles tendon were 4.5 cm to 11.5 cm, with an average of 6.8 cm in length. The wounds were managed with VSD after primary surgery, and then stage Ⅰ surgery were followed to reconstruct the defects in Achilles tendon region with perforator flap of lateral femoral circumflex artery. The sizes of chimeric flaps were 6.5 cm×5.0 cm to 18.0 cm×6.5 cm, including 3 lobuated flaps. The fascia grafts were 5.5 cm to 12.0 cm, with an average of 7.0 cm. Scheduled postoperative follow-ups were conducted in outpatient clinic and via telephone or WeChat interviews, together with the advices for rehabilitation training. Postoperative functions of the Achilles tendon and ankle function were evaluated using Arner-Lindholm criteria and the ankle and hindfoot functional score of American Orthopaedic Foot and Ankle Society (AOFAS).Results:All of the 9 chimeric flaps survived and all the donor sites had primary healing. All patients were entered into the postoperative follow-up for 10 to 66 months, with 14.6 months in average. One chimeric flap was found bulky and a flap thinning surgery was further carried out in 3 months under the request of patient. The rest of patients were satisfied with the appearance and texture of the flaps. The range of ankle plantar flexions was found at 42.9°±1.8° and the dorsal flexions was at 16.2°±2.5°. There was no significant decrease in circumference and no discomfort or muscle re-rupture in the affected legs. Thompson test was found negative. There was no wound related complications during follow-up. Reconstructive surgery were found effective based on Arner-Lindholm criteria, with excellent in 6 patients, good in 2 and 1 in fair. The ankle and subtalar joint function was evaluated according to the ankle-hindfoot function score of AOFAS, with 7 patients scored 90-100 point and 2 scored 75-89 point, and 7 patients were in excellent and 2 in good.Conclusion:The chimeric perforator flap of lateral femoral circumflex artery is safe and reliable in reconstruction of composite tissue defects in Achilles tendon region. It can effectively restore the function and appearance of ankle and hindfoot in patients with composite tissue defects in the Achilles tendon region.

Objective:To explore the clinical effect of thin superficial circumflex iliac artery perforator flap with venous superdrainage in treatment of wound in extremities.Methods:Clinical data of 20 patients who were treated from January 2018 to January 2024 in the Department of Burns and Plastic Surgery, Affiliated Hospital of Zunyi Medical University were retrospectively analysed. The soft tissue defects in extremity were reconstructed with thin perforator flaps of superficial iliac circumflex artery with venous superdrainage. There were 13 patients with upper limb defects and 7 with ankle defects. Of the defects, 12 were of trauma, 2 of tumour resection, 3 of scar release surgery and 3 of donor flat harvesting. The defects ranged from 5.0 cm×4.0 cm to 18.0 cm×7.0 cm in size. During the surgery, portable Doppler was used to detect the perforating branches of the superficial rotational iliac artery and design flaps. The flaps were 5.0 cm×5.0 cm to 20.0 cm×7.0 cm in size, including 16 single-lobed flaps, 3 double-lobed flaps and 1 triple-lobed flaps. The flaps were 2-7 mm in thickness, with an average of 4 mm. Based on the distribution of perforators, the flaps carried the superficial helioiliac artery and the accompanying vein, as well as the superficial helioiliac vein. The superficial helioiliac artery and the accompanying vein were anastomosed during the surgery, and the superficial helioiliac vein was anastomosed to the superficial or deep vein of the recipient site for superreflux. The donor sites were all directly sutured and closed. Postoperative follow-up was conducted by visits of outpatient clinic, and via telephone and WeChat interviews. The survival and appearance of the flaps and complications were observed.Results:A total of 22 arteries and 42 veins of the 20 flaps were anastomosed in surgery. All flaps survived. The donor sites were closed in the first stage. No vascular compromise occurred. One patient had early exudate under the flap on the exposed wound of interphalangeal joint, which healed after routine dressing change and drainage. All patients were included in the postoperative follow-up, with a peroid over 5 to 40 months, at 10.8 months in average. The flaps were thin and soft, with good wear resistance and without pigmentation. The healing of donor sites was good except 1 donore site that had early lymphatic leakage, which was cured after compression and drainage. A linear scar left at the donor sites and it was acceptable to the patients.Conclusion:The treatment of defective soft tissue wounds in extremities using thin perforator flap with venous superdrainage of the superficial circumflex iliac artery is safe and feasible. No further flap thinning surgery is required, and there is a reliable clinical effect.

Objective:To evaluate the clinical effect of antibiotic-loaded bone cement implantation combined with free chimeric tissue flap transplantation in the sequential treatment of severe gouty wounds.Methods:This study was a retrospective observational study. From July 2019 to July 2022, 11 male patients with severe gouty wounds who were aged 33 to 71 years and met the inclusion criteria were admitted and treated at the Affiliated Hospital of Zunyi Medical University. The wounds were located on the hands in 2 cases, the ankles in 5 cases, and the feet in 4 cases. After debridement, the wound area ranged from 5.0 cm×4.0 cm to 22.0 cm×6.0 cm. All wounds were sequentially repaired with antibiotic-loaded bone cement implantation combined with free chimeric tissue flaps transplantation. Two cases were repaired by free perforating branch of superficial circumflex iliac artery with chimeric osseous flaps, with the areas of harvested skin flaps being 5.5 cm×4.0 cm and 8.0 cm×6.0 cm, respectively, and the volumes of iliac bone flaps being 2.0 cm×2.0 cm×1.5 cm and 3.5 cm×2.0 cm×2.0 cm, respectively. Two cases were repaired by free perforating branch of deep circumflex iliac artery with chimeric osseous flaps, with the areas of harvested skin flaps being 6.0 cm×4.0 cm and 7.5 cm×5.0 cm, respectively, and the volumes of iliac bone flaps being 2.0 cm×1.5 cm×1.5 cm and 2.5 cm×2.0 cm×1.5 cm, respectively. Seven cases were repaired by free chimeric myocutaneous flaps based on the descending branch of the lateral circumflex femoral artery. The areas of harvested skin flaps ranged from 9.5 cm×6.0 cm to 25.0 cm×6.5 cm, and the volumes of muscle flaps ranged from 4.0 cm×3.0 cm×2.0 cm to 6.0 cm×5.0 cm×2.5 cm. The donor site wounds were directly sutured. The chimeric tissue flap was freely transplanted to the recipient wound site, of which the iliac bone graft was used to fill the bone defect, the muscle flap was utilized to fill the wound cavity, and the skin flap was employed to cover the wound surface; the arteries and veins in the vascular pedicle were anastomosed with those in the recipient area. At admission and 3 days post antibiotic-loaded bone cement implantation, the changes in white blood cell count, neutrophil and hypersensitive C-reactive protein level, as well as the bacterial culture of wound secretions specimen, and the growth of granulation tissue were observed. After stage Ⅱ surgery, the survival of transplanted chimeric tissue flaps, the occurrence of vascular crisis, and the healing of wounds in donor and recipient sites were observed. During follow-up, the blood supply, appearance, and texture of the transplanted tissue flaps in the recipient sites, the function and appearance of the affected limbs and fingers, and the complications in the donor and recipient sites were observed.Results:Three days post antibiotic-loaded bone cement implantation, white blood cell count, hypersensitive C-reactive protein level, and neutrophil significantly decreased compared with those at admission (with Z values of -2.93 and -2.93 respectively, t=8.63, P<0.05). At admission, all patients exhibited bacterial infections with redness and swelling around the wounds. Three days post antibiotic-loaded bone cement implantation, bacterial cultures of wound secretions specimen were negative, local redness resolved, and granulation tissue showed good growth. After stage Ⅱ surgery, all chimeric flaps survived without vascular crises. The wound healing in the recipient site of the dorsum of the foot in one patient was poor and delayed but healed after dressing changes; all the other recipient sites in remaining patients healed successfully. The donor incision healed well in all patients. During 6 to 24 months of follow-up, the flaps in the recipient area demonstrated good blood circulation, texture, and appearance. Bone healing was achieved in 4 patients with iliac grafts. Nine patients with lower limb wounds were able to bear weight, and the functions including gripping, palm alignment, and finger alignment were significantly improved in 2 patients with hand wounds. No significant complications were observed in donor or recipient sites. Conclusions:In treating patients with severe gouty wounds, the sequential strategy of stage Ⅰ debridement with antibiotic-loaded bone cement implantation followed by stage Ⅱ free chimeric osseous flaps or myocutaneous flaps repair can achieve effectively control of postoperative wound infection, promote wound healing, and well restore the functions of affected finger or limb with no obvious complications, which is worthy of promotion for clinical application.

Objective:To investigate the effects of applying the lateral circumflex femoral artery chimeric perforator flap in repairing composite tissue defects in the ankle and foot area.Methods:This study was a retrospective observational study. From January 2018 to December 2023, 12 patients with composite tissue defects in the ankle and foot area who met the inclusion criteria were admitted to the Department of Burns and Plastic Surgery of the Affiliated Hospital of Zunyi Medical University, including 9 males and 3 females, aged from 4 to 64 years. The causes of the injuries included traffic accident injuries in 7 cases, wringing injuries in 2 cases, crush injuries in 2 cases, and fall injury in 1 case. All patients had combined skin and soft tissue defects, with the defect areas ranging from 10.0 cm×5.0 cm to 22.0 cm×7.0 cm. Among them, 7 patients had ankle joint capsule defects sized from 3 cm×2 cm to 6 cm×5 cm; 3 patients had Achilles tendon defects ranged from 4 to 8 cm in length; 1 patient had an extensor hallucis longus tendon defect of 4 cm in length; 1 patient had an extensor digitorum longus tendon defect of 10 cm in length. All patients underwent repair of the composite tissue defects using the lateral circumflex femoral artery chimeric perforator flaps. Flaps with sizes ranging from 11.0 cm×5.5 cm to 24.0 cm×6.5 cm were used to repair skin and soft tissue defects, and fascia lata flaps with sizes ranging from 4.0 cm×2.5 cm to 17.0 cm×2.0 cm were used to repair joint capsule and tendon defects. The flap donor area wound was closed by suturing. Postoperatively, regular follow-up was conducted to observe the survival of the flaps after surgery, the repair of the defects, the healing of the incisions in the flap donor area, the occurrence of complications, the appearance and texture of the flaps, the scar formation in the surgical area, and the movement of the lower limb on the flap donor side. At the last follow-up, the American Orthopaedic Foot and Ankle Society scoring standard was used to evaluate the function of the ankle and foot.Results:All patients were followed up for 2 to 38 months, with an average of 8.7 months. After surgery, all flaps survived, and all wounds in the recipient areas healed. In patients who underwent ankle joint capsule and tendon reconstruction, there was no swelling in the joints, and the joint movements were good without foot drop or toe drop deformities. All incisions in the flap donor areas were healed without any complication. The families of 2 children took their children back to the hospital for flap thinning at 3 and 4 months respectively after surgery because they felt that the flaps were bulky. The other patients were satisfied with the appearance and texture of the flaps. One child had obvious scar hyperplasia in the early stage, and the scar gradually faded after external application of anti-scar medications and pressure treatment. The scars of the other patients were not obvious. All patients had normal lower limb movements on the flap donor side. At the last follow-up, the functions of the ankle and foot were rated as excellent in 8 cases and good in 4 cases.Conclusions:The lateral circumflex femoral artery chimeric perforator flap is flexible in design. It can repair the composite tissue defects in the skin and soft tissue, joint capsules, and tendons of the ankle and foot simultaneously. There are no obvious complications in the flap donor area. Most patients are satisfied with the appearance of the flap in the recipient area. The flap is soft in texture, and the functions of the ankle and foot are well restored.

Objective:To evaluate the value of multi-slice spiral CT (MSCT) in the diagnosis of liver metastases with rich blood supply.Methods:The clinical data and imaging data of 19 patients with liver metastases with rich blood supply admitted to the 921st Hospital of the Joint Logistics Support Force of Chinese People′s Liberation Army from September 2018 to September 2023 were retrospectively analyzed, and the number, location, shape, size of the lesions and the images of CT plain scan and dynamic enhanced scan were analyzed.Results:Among the 19 patients, there were 18 multiple cases and 1 single case. A total of 108 lesions were found. There were 62 cases (57.4%) in the right lobe of liver and 87 cases (80.6%) in the peripheral part of liver. The form of circular or quasi-circular, there were 99, irregular shape or lobed 9. The focal diameter was 0.6-6.8 cm. CT plain scan showed that 99 lesions showed slightly low density, and the other 9 lesions showed equal density relative to the background liver. In the dynamic enhanced scan, 108 lesions in arterial stage showed high-density enhancement, 97 lesions showed circular enhancement, and 11 lesions showed nodular enhancement. Among them, 77 lesions had moderate to obvious intensification density. Of the 108 lesions in the portal vein stage, 31 lesions showed moderate to obvious enhancement density, 49 lesions showed slightly low clearance density, and 28 lesions showed continuous enhancement density. In the delayed stage, all 108 lesions showed slightly low density.Conclusions:The main features of liver metastases with rich blood supply are: low density on plain CT scan, annular or nodular enhancement in the arterial phase of enhanced CT scan, and the peak of enhanced density can be in the arterial phase or the portal vein phase. Combined with clinical data, CT can make a correct diagnosis.

Objective:To explore the clinical application value of infrared thermal imaging in assisting the repair of complex joint tissue defects in children using the lateral femoral circumflex artery (LFCA) chimeric perforator flap.Methods:A retrospective analysis was conducted on clinical data from the Department of Burns and Plastic Surgery at the Affiliated Hospital of Zunyi Medical University between May 2019 and September 2023. The study included cases where the LFCA perforator chimeric flap was used to repair complex joint tissue defects in children. Preoperative perforator mapping was performed using an infrared thermal imaging device combined with a portable Doppler. The flap and fascial flap were designed based on the distribution of hot spots and thermal lines. Intraoperative confirmation of perforator distribution was carried out. Postoperative follow-ups were conducted to assess flap survival, the need for secondary thinning procedures, wound healing status, donor site scarring, joint swelling, and functional recovery.Results:A total of 11 pediatric patients were enrolled, including 8 males and 3 females, aged 2 to 14 years (mean age: 5.8 years). The injury mechanisms included traffic accidents (6 cases), wheel spoke injuries (2 cases), falls (2 cases), and heavy object crush injuries (1 case). Affected joints included the wrist (1 case), knee (2 cases), and ankle (8 cases). Associated injuries included metacarpal fracture (1 case), metatarsal fractures (2 cases), and extensor tendon defects (1 case). Tendon defect length was 3 cm, joint capsule defect area ranged from 2 cm × 3 cm to 4 cm × 6 cm, and fascial flap size ranged from 2 cm × 4 cm to 2 cm × 14 cm. Skin defect area ranged from 5 cm × 3 cm to 16 cm × 9 cm, and flap size ranged from 6 cm × 4 cm to 15 cm × 5 cm. Preoperative infrared thermography identified 28 hot spots, with 26 perforators confirmed intraoperatively (positive rate: 92.9%). Thermal line distribution zones consistently corresponded to perforator branches. All 11 flaps survived, with primary healing achieved at both donor and recipient sites. Follow-up duration ranged from 6 to 36 months (mean: 10.5 months). All recipient sites exhibited soft flap texture. One case required secondary debulking due to flap bulkiness. Donor sites showed only linear scarring. During follow-up, no significant joint swelling, functional impairment, or joint dislocation was observed.Conclusion:Infrared thermal imaging-assisted perforator mapping for the design of LFCA chimeric perforator flaps is a safe and reliable method for repairing complex joint tissue defects in children. It provides accurate perforator localization, offering significant clinical value for the design and harvesting of LFCA chimeric perforator flaps in pediatric patients.
