Objective To summarise a clinical experience of nursing care for 3 children who were treated with ECMO for sepsis and complicated with fulminant myocarditis.Methods Clinical data in nursing cares for 3 children treated with ECMO for sepsis and complicated with fulminant myocarditis were collected and analysed,with the spotted difficulties in nursing care and proposed coping strategies.Results The 3 children survived and were transferred out of the(pediatric intensive care unit,PICU)with stable vital signs and haemodynamics after emergency treatment with ECMO and continuous renal replacement therapy(CRRT).Conclusion Children with sepsis leading to myocardial depression and subsequent heart failure require close observation of the changes and consequently specialised cares after having initiated an ECMO in emergency treatment.This includes ensuring proper fixation of the cannulas,managing anticoagulation,monitoring the speed,flow rate and pressure of ECMO,management of body temperature,skin care,sedation and pain,as well as prevention of complications.These nursing care measures would improve the survival rate after the treatment of ECMO.

Objective:To access the therapeutic efficacy of newly-designed digital cholangioscope-assisted bedside one-stage lithotomy and biliary drainage for severe acute cholangitis caused by choledocholithiasis.Methods:Data of 26 patients were retrospectively analyzed, who were admitted into the intensive care unit (ICU), Zhongda Hospital, Southeast University, due to choledocholithiasis induced by severe acute cholangitis and underwent cholangioscope-assisted bedside one-stage lithotomy and biliary drainage from June 2020 to February 2022. Clinical outcomes were analyzed.Results:The time interval from disease onset to endoscopic intervention was 36.2±15.5 hours, with 7.2±4.9 hours from ICU admission to endoscopic intervention. Technical success rate was 100.0% in one-stage stone removal and biliary drainage. Except for one mild pancreatitis, no other complication occurred. Acute physiology and chronic health evaluation (APACHE)Ⅱ and sequential organ failure assessment (SOFA) scores prior to endoscopic intervention were 25.2±6.6 and 11.9±3.5, respectively. APACHE Ⅱ scores at day 1, 3, and 7 after endoscopic intervention were 21.7±6.5, 17.2±6.8 and 12.7±7.7, respectively, and SOFA scores were 10.6±2.9, 8.4±3.0 and 5.4±3.7, respectively, all of them were lower than those before operation ( P<0.001). The lengths of ICU stay and total hospitalization were 9.7±5.0 days and 12.8±4.5 days, respectively. In-hospital mortality occurred in 3 (11.5%) patients. According to a 6-month follow-up, one patient died of pneumonia, and another died of acute myocardial infarction. No acute cholangitis re-occurred in those survivors. Conclusion:Newly-designed digital cholangioscope-assisted bedside one-stage lithotomy and biliary drainage demonstrate significant improvements in prognosis, highlighting its safety in managing severe acute cholangitis.

Objective:To evaluate a newly designed basket fit for digital cholangioscope in non-radiation endoscopic lithotomy for common bile duct stones.Methods:Seventy-eight patients who underwent non-radiation endoscopic removal of common bile duct stones at Zhongda Hospital Southeast University between February and October 2021 were enrolled in the randomized controlled trial, and were randomly assigned into the new basket group ( n=35) and the conventional basket group ( n=43) by drawing lots. Procedures of cholangioscope-based biliary exploration and stone removal by baskets, volume of water irrigation, time lengths of biliary exploration, stone removal and whole endoscopic procedure, and adverse events were compared. Results:Compared with the conventional basket group, the new basket group needed less biliary explorations (1.08±0.28 VS 2.30±0.51, t=-12.535, P<0.001), smaller volume of water irrigation (46.14±11.89 mL VS 78.62±10.09 mL, t=-13.052, P<0.001), and shorter time of biliary exploration and stone removal (9.69±2.97 min VS 12.67±2.51 min, t=-4.815, P<0.001) and whole endoscopic procedure (30.17±7.19 min VS 33.44±6.69 min, t=-2.076, P=0.041). The incidence of adverse events was not significantly different between the two groups [5.7% (2/35) VS 11.6% (5/43), χ2=0.826, P=0.363]. Conclusion:This newly designed basket can facilitate digital cholangioscope-guided non-radiation endoscopic removal of common bile duct stones with the advantages of shorter operation time, less exploration time of choledochoscopy and smaller volume of water irrigation.

Objective: To explore the clinical effects of free superficial peroneal artery perforator flaps in repairing skin and soft tissue defects of the hallux. Methods: A retrospective observational study was conducted. From January 2020 to January 2021, 13 patients with skin and soft tissue defects of the hallux who met the inclusion criteria were admitted to Department of Foot and Ankle Surgery of Ruihua Affiliated Hospital of Soochow University, including 12 males and 1 female, aged 26 to 53 years. Before operation, the perforating point of the superficial peroneal artery perforator was located by color Doppler ultrasound on the calf on the same side of the affected hallux and marked on the body surface. The operation was performed under spinal anesthesia combined with continuous epidural anesthesia. The area of skin and soft tissue defect after debridement was 4.5 cm×2.5 cm to 12.0 cm×3.0 cm. According to the size and shape of the wound, the superficial peroneal artery perforator flap was designed with the line between the fibular head and the lateral malleolus tip parallel shifting 2 cm to the tibial side as the flap axis line, and the perforating point of the perforator near the midpoint of the axis line as the center. The cut area of the flap was 5.0 cm×3.0 cm to 13.0 cm×4.0 cm, and part of the deep fascia was cut when the pedicle was freed. The donor site wound was sutured directly. During the operation, the number and type of the perforator and the cutting time of the flap were recorded, and the length of the perforator pedicle and diameter of the perforator were measured. The survival of the flap, the healing time and the healing condition of the donor and recipient areas were recorded after operation. The color, texture, elasticity of the flap, standing and walking functions of patients, the recovery of the donor area, and the patients' satisfaction with the recovery of the donor and recipient areas were recorded during the follow-up. At the last follow-up, the sensation of the flap was evaluated by the British Medical Association sensory function evaluation standard, the function of the affected limb was evaluated by the American Society of Foot and Ankle Surgery scoring system, and the excellent and good rate of the function of the affected limb was calculated. Results: A total of 13 perforators of the superficial peroneal artery were detected during the operation, all of which were septocutaneous perforators, and the perforator diameter was 0.3 to 0.5 mm. The vascular pedicle length was 2 to 5 cm. Flap cutting time was 11 to 26 minutes. The flaps of 13 patients all survived completely. The wounds at the donor and recipient sites healed well 9 to 18 days after operation. During follow-up of 6 to 14 months, the flaps had good color, texture, and elasticity; 11 patients had no obvious bloated appearance, and the other 2 patients underwent flap thinning and plastic surgery in the second stage because of their bloated appearance; all the patients returned to normal walking and standing functions. There was only one linear scar left in the donor site, with no obvious scar hyperplasia or hyperpigmentation. All the patients were satisfied with the recovery of the donor and recipient areas. At the last follow-up, the sensation of the flap was evaluated as grade S₃ in 2 cases, grade S₂ in 9 cases, and grade S₁ in 2 cases; the function of the affected limb was evaluated as excellent in 7 cases and good in 6 cases, with an excellent and good rate of 100%. Conclusions: The free superficial peroneal artery perforator flap has relatively constant vascular anatomy, which is thin and wear-resistant, with less damage to the donor site after flap excision, and can preserve the shape and function of the hallux to the greatest extent. It is an effective method for repairing skin and soft tissue defect of the hallux.

Objective: To investigate the regularity of sensory recovery after repairing the wounds on the wrist and back of hand with anterolateral femoral flap without nerve anastomosis. Methods: A cross-sectional study was conducted. From January 2018 to December 2020, patients who underwent free anterolateral femoral flaps without nerve anastomosis to repair wounds on the wrist and back of hand and met the inclusion criteria in Changshu Hai Yu Health Centre and Suzhou Ruihua Orthopedic Hospital were included in this study. Depending on the time interval between the day of the patient's surgery and the day of the cross-sectional survey, 80 patients were divided into 6-month group (15 males and 5 females, aged 22-63 years), 12-month group (16 males and 4 females, aged 21-65 years), 18-month group (15 males and 5 females, aged 25-61 years), and 24-month group (14 males and 6 females, aged 20-65 years), with 20 patients in each group. The area of skin and soft tissue defects after debridement ranged from 6.0 cm×4.5 cm to 18.0 cm×9.0 cm. Anterolateral femoral flaps were cut with areas of 7 cm×5 cm to 20 cm×10 cm and a thickness of 1.0 to 2.5 cm. Each transplanted flap was divided into A (proximal), B/D (bilateral), C (distal), and E (central) regions. The pain sensation, touch sensation, cold sensation, warmth sensation, and two-point discrimination (2-PD) in the aforementioned five regions and the differences in the five senses of the whole flap were tested and compared. Data were statistically analyzed with one-way analysis of variance, Fisher's exact probability test, chi-square test, or McNemar test. Results: In A region of anterolateral femoral flap without nerve anastomosis, compared with those in 6-month group, the pain sensation, touch sensation, cold sensation, and warmth sensation of flap of patients in 12-month group were significantly recovered (with χ² values of 10.10, 14.55, 12.13, and 4.29, respectively, P<0.05 or P<0.01); compared with that in 12-month group, the warmth sensation of flap of patients in 18-month group recovered significantly (χ²=5.23, P<0.05). In B region, compared with those in 6-month group, the pain sensation, touch sensation, and cold sensation of flap of patients in 12-month group recovered significantly (with χ² values of 5.58, 3.96, and 4.29, respectively, P<0.05); compared with those in 12-month group, the pain sensation, touch sensation, cold sensation, and warmth sensation of flap of patients in 18-month group recovered significantly (with χ² values of 5.58, 3.96, 7.03, and 12.38, respectively, P<0.05 or P<0.01). In C region, compared with that in 6-month group, the pain sensation of flap of patients in 12-month group recovered significantly (χ²=4.80, P<0.05); Compared with that in 12-month group, the warmth sensation of flap of patients in 18-month group recovered significantly (χ²=10.16, P<0.01). In D region, compared with those in 6-month group, the pain sensation, touch sensation, and cold sensation of flap of patients in 12-month group recovered significantly (with χ² values of 5.58, 4.29, and 3.96, respectively, P<0.05); compared with those in 12-month group, the pain sensation, touch sensation, cold sensation, and warmth sensation of flap of patients in 18-month group recovered significantly (with χ² values of 5.58, 4.29, 3.96, and 10.10, respectively, P<0.05 or P<0.01). In E region, compared with that in 6-month group, the cold sensation of flap of patients in 12-month group recovered significantly (χ²=4.80, P<0.05); compared with those in 12-month group, the pain sensation, touch sensation, and warmth sensation of flap of patients in 18-month group recovered significantly (with χ² values of 6.47, 4.91, and 9.23, respectively, P<0.05 or P<0.01). The five senses in the 5 regions of flap of patients in 24-month group were similar to those in 18-month group (P>0.05). The recovery of 2-PD in the 5 regions of flap of patients was similar between the two adjacent groups (P>0.05). In 12-month group, the recoveries of pain sensation, touch sensation, and cold sensation of flap of patients in A region were better than those in the other 4 regions (P<0.05 or P<0.01), the recovery of warmth sensation was better than that of B region, C region, and E region (P<0.05 or P<0.01); in 18-month group, the recovery of pain sensation, touch sensation, cold sensation, and warmth sensation of flap of patients in A region of was better than those in area C region (P<0.05). Compared with those in 6-month group, the pain sensation, touch sensation, and cold sensation of the whole flap of patients in 12-month group recovered significantly (with χ² values of 7.62, 7.03, and 5.58, respectively, P<0.05 or P<0.01). Compared with the 12-month group in which 10, 11, 10, and 4 patients had a recovery of pain, touch sensation, cold sensation, and warmth sensation in the whole flap, the 18-month group had significantly more patients with sensations recovered, which were 17, 17, 16, and 14, respectively (with χ² values of 5.58, 4.29, 3.96, and 10.10, respectively, P<0.05 or P<0.01). The five senses of the whole flap of patients in 24-month group were similar to those in 18-month group (P>0.05). Conclusions: In the anterolateral femoral flap without nerve anastomosis for repairing wounds on the wrist and back of hand, the sensation gradually recovered from the proximal end to the distal end. The sensation of touch, pain, and cold began to recover from 6 months after operation, and entered the stable recover period at 18 months after operation. Warmth sensation began to recover from 12 months after operation, and entered the stable recovery period at 18 months after operation. The 2-PD of most flaps was still not recovered 2-year after operation.

Objectives: . Despite the efficacy of surgical treatments, the high rate of recurrence in juvenile nasopharyngeal angiofibroma (JNA) after surgery remains an unresolved problem. The present study comprehensively analyzed the risk factors and characteristics of JNA recurrence, providing clinical guidance for reducing recurrence. Methods: . A total of 123 patients who underwent surgery for JNA between 1997 and 2019 at a single hospital were analyzed retrospectively. Univariate and multivariate analyses were used to assess the clinical risk factors for the recurrence of JNA. The relapse-free survival and annual cumulative recurrence rates were analyzed for subgroups defined according to clinical parameters. Results: . After screening, 78 of the 123 patients were included in the present study. The main risk factors associated with JNA recurrence included the year of diagnosis, tumor size, sphenoid bone invasion, Radkowski stage, surgical approach, and intraoperative bleeding. Importantly, the surgical approach and sphenoid bone invasion were independent prognostic factors affecting recurrence. Patients who underwent endoscopic surgery without sphenoid bone invasion exhibited longer relapse-free survival. In the present study, the overall cumulative recurrence rate of JNA was 38.7%, and recurrence occurred mainly in the first year after the initial surgery. Conclusion . Endoscopic surgery achieved better relapse-free survival in JNA patients, and patients with sphenoid bone invasion should be carefully explored to avoid residual JNA. The recurrence rate of JNA differed among subgroups defined based on clinical parameters and was highest in the first year after surgery. Computed tomography or magnetic resonance imaging, along with close follow-up, should be performed strictly within 1 year after the primary operation.

Objective:To investigate the medium- and long-term efficacy of peroral endoscopic myotomy (POEM) for esophageal diverticulum and the risk factors for postoperative recurrence.Methods:A retrospective study was conducted on 31 cases of esophageal diverticulum who were treated by POEM in Zhongda Hospital, Southeast University from May 1st 2016 to August 1st 2019. The Eckardt score, the operative success rate, and the recurrence rate after the operation were observed and recorded. Multivariate logistic regression analysis was performed to explore the risk factors for postoperative recurrence.Results:POEM was successfully completed in all 31 patients, who were followed up for 30.6±11.1 months (20-63 months). The Eckardt score before the operation was 8.2±2.4, and was 1.4±0.7, 1.4±1.1, 1.3±1.1, and 1.3±0.9 at 1, 6, 12 and 24 months, respectively after the operation, which significantly decreased at all follow-up time points ( P<0.001). The success rates at 1, 6, 12, and 24 months after the operation were 96.8% (30/31), 90.3% (28/31), 90.3% (28/31) and 90.3% (28/31), respectively. Three patients suffered symptom relapse, with an overall recurrence rate of 9.7% (3/31). Logistic regression analysis showed that the disease duration ( P=0.038, OR=1.041, 95% CI: 1.002-1.080) and preoperative Eckardt score ( P=0.024, OR=2.299, 95% CI: 1.117-4.728) were risk factors for postoperative recurrence of POEM. Conclusion:POEM is safe and effective for esophageal diverticulum. Patients with long disease duration and high preoperative Eckardt score are associated with recurrence.

Objective: To explore HIV-1 drug resistance and influencing factors among people living with HIV/AIDS before antiretroviral therapy in Liangshan Yi Autonomous Prefecture (Liangshan). Methods: Between January 1 and June 30, in both 2017 and 2018, a cross-sectional survey was conducted in Liangshan HIV-1 pol sequences were gathered and analyzed according to WHO Guidelines on HIV drug resistance surveillance of 2014. Both HyPhy 2.2.4 and Cytoscape 3.6.1 software were used to analyze the drug resistant strains of HIV-1 transmission network. Results: A total of 464 people living with HIV/AIDS was recruited. The proportion of HIV-1 CRF07_BC subtype was 88.6% (411/464), with HIV-1 drug resistance rate was 9.9% (46/464). The HIV-1 drug resistance rates of non-nucleoside reverse transcriptase inhibitors (NNRTI), nucleoside reverse transcriptase inhibitors(NRTI) and protease inhibitors (PI) were 6.7% (31/464), 1.9% (9/464) and 0.4% (2/464) respectively. New recombinant strains of HIV-1 URF_01BC subtype was independently clustered according to the drug resistant mutation sites. Results from the multivariate logistic analysis showed that injected drug users group had higher risk on HIV-1 drug resistance (aOR=3.03, 95%CI:1.40-6.54) than heterosexual group among people living with HIV/AIDS. Conclusions HIV-1 drug resistance rate had already been in a high level before antiretroviral therapy was in place. The newly identified recombinant strains of HIV-1 URF_01BC subtype were independently clustered according to the drug resistant mutation sites. It was necessary to strengthen the prevention of the HIV-1 drug resistant strains transmission.

Objective: To investigate the clinical effects of extra-long lateral femoral supercharged perforator flaps in repair of ankle and foot wounds. Methods: From March 2014 to October 2018, 16 patients with foot and ankle injuries were admitted to our hospital and left large area of wounds on foot and ankle after emergency treatment. There were 13 males and 3 females, with age of 27 to 60 years. The area of the wounds ranged from 14 cm×10 cm to 40 cm×17 cm. The wounds were repaired with extra-long lateral femoral supercharged perforator flaps. The widths of flaps in 8 patients were longer than 8 cm, and the bilobed flaps were designed to repair the wounds. The area of the flaps ranged from 12 cm×5 cm to 40 cm×9 cm. During the operation, 54 perforators were detected, with an average of 3.2 perforators in each flap, and 36 source arteries of perforators were detected. The blood vessel trunk of 15 patients was descending branch of the lateral femoral circumflex artery, and their supercharged mode was anastomosis of the bulky perforator of descending branch of the lateral femoral circumflex artery with the oblique branch of the lateral femoral circumflex artery and/or medial femoral circumflex artery or the descending branch of superficial illiac circumflex artery. The blood vessel trunk of 1 patient was oblique branch of the lateral femoral circumflex artery, and the supercharged mode of the patient was anastomosis of the oblique branch of the lateral femoral circumflex artery with the bulky perforator of the descending branch of the lateral femoral circumflex artery. The wounds were covered with the flaps after supercharged blood vessel anastomosis, and blood vessels in the donor sites were anastomosed with those in the recipient sites. The donor site was sutured directly. The survival of the flap after the operation and healing time of the wound, and the flap condition, the two-point discrimination distance of flap in patients who were reconstructed with sensation, the recovery of the ankle function, and the appearance of the donor site during follow-up were recorded. Results: A total of 17 flaps in 16 patients were designed, including 8 bilobed flaps and 9 non-lobulated flaps. Sixteen flaps in 15 patients survived. Vascular crisis occurred in the flap of one patient, and the flap survived when the vascular crisis was relieved by the second operation. The healing time of foot and ankle wounds ranged from 12 to 90 days. All the lateral femoral donor sites healed completely. During follow-up of 8 to 48 months, flaps in 2 patients were slightly bloated and were trimmed in 6 months after the operation. The other flaps were with good appearance, soft texture, good elasticity, and no rupture or ulceration. The two-point discrimination distances of flaps ranged from 7 to 16 mm in 8 patients who were reconstructed with sensation, and the other flaps recovered protective sensation. The flexion and extension function of ankle joint recovered well, and the walking function was not affected significantly. All donor sites formed linear scar, with no deep tissue infection such as osteomyelitis. Conclusions The application of extra-long lateral femoral supercharged perforator flaps to repair the large area of wounds in foot and ankle can significantly reduce damage to donor sites and has advantages of rich blood supply and good safety, thus it has satisfactory clinical effects.

Objective: To explore the clinical effect of bilateral anterolateral thigh flaps in repairing complex wounds of foot and ankle. Methods: From April 2014 to June 2017, 16 patients with complex foot and ankle wounds were treated in Ruihua Hospital Affiliated to Soochow University. There were 15 males and 1 female, aged from 12 to 73 years. Two of them had two wounds for each, the area of which was from 4 cm ×5 cm to 6 cm×10 cm. Fourteen cases were single-wounds, the area of which ranged from 11 cm×8 cm to 42 cm×15 cm. According to the wound surfaces, the wide wound cloth was divided into two pieces of cloth with a width less than 8 cm. The double-leaf skin flap was designed at the point of the perforating branch of the skin flap located by B-ultrasound on the iliac-patellar connecting line of the donor area. The course of the origin artery of the skin perforating branch of the skin flap was observed by DSA image. If the perforating branch of the double-leaf skin flaps was the common origin artery, the two adjacent wounds would be repaired directly. If the perforator of the double-leaf skin flaps is not the common artery, the double-leaf skin flaps were cut separately. After the pedicle division, the perforator vessels of the high perforator skin flaps were anastomosed with the distal end of the medial circumflex lateral femoral artery of the low perforator skin flaps to form a new parallel double-leaf skin flaps, which were then assembled or lobed to the recipient area. Flap donor sites were sutured directly. Results: 11 cases were repaired with parallel bilateral anterolateral thigh flaps with double perforators, and 5 cases were repaired with new parallel bilateral thigh flaps formed by anastomotic bridging of perforator vessels. The area of the flaps ranged from 5 cm×6 cm to 8 cm×22 cm. All the 16 flaps survived and the donor site wounds healed in one stage. Five cases underwent internal fixation removal and skin flap thinning 6 to 10 months after operation. Follow-up for 6 to 18 months showed that the skin flaps were of good color and texture, and the sensation of the flaps ranged from S1 to S3. Linear scars were left in all donor sites and lower limb movements were normal. Conclusions It is a good method to repair complex foot and ankle wounds with bilateral anterolateral thigh flaps, and it has the advantages of flexible design, less damage to donor site and good blood supply of the flap.
