BACKGROUND:The repair and management of ful-thickness skin defects resulting from burns and chronic wounds remain a significant unmet clinical chal enge. Using epidermal stem cel s and keratinocyte growth factor for ful-thickness wound repair is a promising approach. Low-frequency electromagnetic fields which are a non-invasive physical stimulation therapy have been recognized as a good method to enhance wound healing. OBJECTIVE:To develop a new strategy to accelerate wound healing by transplanting transfected epidermal stem cel s and keratinocyte growth factor and treating with low-frequency electromagnetic fields in a mouse model. METHODS:Epidermal stem cel s from Sprague-Dawley neonatal rats were isolated and cultured in vitro, then the cel s were labeled with 5-bromo-2-deoxyuridine and transfected by Ad-KGF, a recombinant adenovirus carrying the keratinocyte growth factor. Mice were given to create ful thickness skin wound on the dorsum and randomly assigned to four groups:control group, transplantation of epidermal stem cel s group, transplantation of keratinocyte growth factor gene modified epidermal stem cel s group, and transplantation of keratinocyte growth factor gene modified epidermal stem cel s plus low-frequency electromagnetic field exposure group. RESULTS AND CONCLUSION:The best healing pattern was observed in the keratinocyte growth factor gene modified epidermal stem cel s plus low-frequency electromagnetic field exposure group (P<0.05) at days 9 and 16. 5-Bromo-2-deoxyuridine labeled cel s existed in the wound in the treated groups at day 9. A significantly increased expression of endogenous keratinocyte growth factor was detected in the transplantation of Keratinocyte Growth Factor gene modified epidermal stem cel s group, and transplantation of keratinocyte growth factor gene modified epidermal stem cel s plus low-frequency electromagnetic field exposure group at day 16. A wel-advanced epithelialization was observed in transplantation of keratinocyte growth factor gene modified epidermal stem cel s plus low-frequency electromagnetic field exposure group at days 16 and 30. These results suggest that low-frequency electromagnetic fields enhanced wound healing fol owing the transplantation of keratinocyte growth factor gene modified epidermal stem cel s.

Objective:To investigate the ocular clinical manifestations in pediatric patients with incontinentia pigmenti (IP).Methods:A case series study was carried out and a retrospective analysis was performed.Clinical data of 13 pediatric patients with IP treated from January 2013 to December 2019 in Xijing Hospital were collected.All the patients underwent regular ophthalmologic examination.Three patients accepted fundus fluorescein angiography and six eyes of five patients were treated with retinal photocoagulation or anti-vascular endothelial growth factor (VEGF) intravitreal injection according to severity of the condition.The follow-up period ranged from 6 months to 6 years.The medical history, family history, systemic manifestations, ocular characteristics, diagnosis, treatment as well as ocular and systemic changes during follow-up were recorded and analyzed.This study followed the Declaration of Helsinki and the study protocol was approved by the Ethics Committee of Xijing Hospital, Fourth Military Medical University (No.KY20203287-1).Results:All the 13 patients were female aged from 5 days to 42 months at first visit, with the average age of 2.0 (1.0, 8.5) months.As for the main skin lesions at first visit, there were 4 cases in erythematous vesicle stage, 3 cases in verrucous exanthema stage, and 6 cases in hyperpigmented stage.There were 7 cases in shrinkage stage during follow-up.Among the 26 eyes of 13 patients, 18 eyes of 10 patients showed ocular anomalies, accounting for 76.9% of total patients (69.2% of total eyes). Among the 13 patients, 8 patients presented bilateral ocular involvement, 2 patients showed unilateral anomalies, and 3 patients had no ocular lesions.The retina was involved in all patients with ocular manifestations.The typical retinal lesions included avascular zone of peripheral retina in 13 eyes, tortuous and dilated retinal vessels in 10 eyes, increased vascular branch in 7 eyes, white linear retinal arteries and partial vascular occlusion in 4 eyes, retinal neovascularization in 3 eyes, total retinal detachment in 2 eyes, and retinal fold with macular lamellar hole in 1 eye.In addition, there was retinal hemorrhage in 11 eyes, retinal pigment changes in 4 eyes, grey ridge lesions in 3 eyes, macular dysplasia in 2 eyes, choroidal atrophy in 1 eye, optic gliosis in 1 eye and yellowish-white retinal exudate in 1 eye.There were also 4 patients with other ocular manifestations, such as strabismus and eyeball atrophy.Retinal photocoagulation was performed in 4 eyes of 3 patients and anti-VEGF intravitreal injection in 2 eyes of 2 patients.The retinal lesions regressed and the condition of patients kept stable during follow-up.Conclusions:The ocular clinical manifestations in patients with IP are usually typical and diverse, and the retinal vascular lesion is the main type.Early diagnosis and timely treatment are of great significance.

Objective:The study aimed was to explore the safety and efficacy of neoadjuvant immunochemotherapy for non-small cell lung cancer (NSCLC).Methods:We retrospectively collected data of all patients who received neoadjuvant immunochemotherapy and chemotherapy for NSCLC followed by surgery in our unit between January 2019 to September 2021.Results:Forty-four patients were diagnosed with NSCLC in a stageⅠ(2 cases), ⅡA(7 cases), ⅡB(11 cases), ⅢA (15 cases), ⅢB (1 case). The average age was 63 years old(range 44-71 years old). Squamous cell carcinoma accounted for 65.91% of all patients. Central lung cancer accounted for the vast majority, with 39 patients (88.64%). There were 19 cases in the neoadjuvant immunochemotherapy group and 25 cases in the neoadjuvant chemotherapy group; the average interval between the end of neoadjuvant therapy and the day of operation was 34 days, including( 33.74±10.66 )days in the immunochemotherapy group and (33.88±11.9) days in the chemotherapy group, and there was no significant difference between the two groups. No grade 3 or more adverse events occurred in all patients. There were 13 cases (63.16%) reached PR (partial response)+ CR (complete response) according to the Response Evaluation Criteria in Solid Tumors (RECIST v. 1.1) in the neoadjuvant immunity group and 11 cases (44.00%) in the neoadjuvant chemotherapy group. There was no significant difference between the two groups. In the neoadjuvant immunochemotherapy group, 9 cases (47.37%) achieved down-staging, In the neoadjuvant chemotherapy group, 8 cases (32.00%) achieved down-staging, there was no significant difference between the two groups. Seven patients (36.84%) in neoadjuvant immunochemotherapy group showed pCR (pathologic complete remission), but there were no patients who reached pCR in the neoadjuvant chemotherapy group., the difference was statistically significant ( P=0.001). Four patients (21.05%) in the neoadjuvant immunochemotherapy group reached mPR (major pathologic response), 6 patients (24.00%) in the neoadjuvant chemotherapy group reached mPR, and the difference was no statistically significant( P= 0.817). Conclusion:The safety of neoadjuvant immunochemotherapy was satisfactory; Compared with neoadjuvant chemotherapy, neoadjuvant immunochemotherapy did not increase the preoperative grade 3 adverse events and prolong the waiting time before operation; neoadjuvant immunochemotherapy had obvious advantages in pCR, which provided the possibility for the cure of tumor.

Objective:To improve the understanding of acute pain after thoracoscopic surgery in patients with early-stage lung adenocarcinoma, to analyze and screen out the independent risk factors that may induce acute postoperative pain. The patients' surgery experience may get improved through the corresponding timely and effective interventions.Methods:We retrospectively reviewed the clinical data of 204 patients with early-stage lung adenocarcinoma who were treated by a single medical team of our center from May 2021 to October 2021, and analyzed the assessment results of acute postoperative pain. Patients were grouped according to the general condition, past medical history, social and spiritual attributes, lesion characteristics, surgical approaches and anesthetic methods. Comparison of proportions of acute postoperative pain between the groups were made, and independent risk factors were identified.Results:A total of 84 males and 120 females were enrolled, with a mean age of(57.9±11.5)years old and a median operation time of 120(110, 145) min. No serious complication or perioperative death occurred in the whole group. Postoperative pain control failed in 76 cases(37.3%), 24 cases(11.8%) suffered from severe postoperative pain, and 33 cases(16.2%) required additional intramuscular injection of strong analgesics after surgery. Those who were younger than 60 years old, with a university degree or above, received two-incision surgery, operated for more than 2 h, received general anesthesia only, or in a state of depression, had significantly higher rates of postoperative acute pain, compared with their respective control groups( P<0.05). The independent risk factors for acute pain after thoracoscopic surgery included age( P=0.002), history of alcoholism( P=0.014), number of incisions( P=0.016), operation time( P=0.010), depression status( P=0.037) and enhanced anesthetic method( P=0.012). Conclusion:A large amount of patients with early-stage lung cancer suffered from acute pain after thoracoscopic surgery, which seriously affected their treatment experience and even quality of life. Young patients with a history of alcoholism and depression status were high-risk groups for postoperative acute pain. Applying Uniportal video-assisted thoracoscopic surgery, reducing the operation time as much as possible, and choosing enhanced analgesic anesthesia represented by epidural block combined with general anesthesia might be effective ways to reduce the probability of acute postoperative pain.
