AIM: To investigate the acute clinical manifestations of cosmetology-related ocular damage(COD).METHODS:Retrospective study. A total of 53 cases(89 eyes)with ocular damage caused by cosmetology from April 2016 to October 2021 were collected. The clinical features were analyzed, including age, gender, affected eye(s), clinical manifestations, injury cause, treatment procedures, and prognosis.RESULTS: All 53 patients were female, aged 22-45 years, with an average age of 28.4±6.7 years. Monocular injuries were observed in 17 patients, and binocular injuries in 36 patients. The same eye could exhibit two or more ocular damage simultaneously. The primary cosmetology procedures causing COD were eyeliner tattooing(38 eyes; 43%), eyelash extensions(18 eyes; 20%), removal of false eyelashes(11 eyes; 12%), mascara application(8 eyes; 9%), double eyelid surgery(6 eyes; 7%), and others(8 eyes; 9%). Major ocular damages included corneal damage(56 eyes; 63%), eyelid contact dermatitis(26 eyes; 29%), conjunctivitis(19 eyes; 21%), reactive eyelid edema(13 eyes; 15%), ocular surface foreign bodies(12 eyes; 14%), bacterial infection of the palpebral margin(10 eyes; 11%), and others(5 eyes; 6%). These 5 eyes included 1 eye(1%)with central retinal artery occlusion caused by periocular injection of hyaluronic acid. The majority of patients(74 eyes)recovered within 1-2 wk with appropriate treatment, while filamentosa keratitis appeared in 3 eyes and the eye with central retinal artery occlusion had poor prognosis.CONCLUSIONS: COD predominantly occurs in young and middle-aged females with cosmetology experience. The most common cosmetology procedure leading to COD is eyeliner tattooing, and corneal damage is the most significant type of COD. COD can be effectively prevented and treated, resulting in a generally favorable prognosis.

Background and objective Different degrees of self-transcendence exist in lung cancer patients,which can stimulate patients'self-awareness and promote them to face negative events in life positively,thus improving pa-tients'quality of life and treatment outcomes.However,there are few reports on self-transcendence in lung cancer patients in China,and the related influencing factors have not yet been clarified.This study aims to investigate the current situation of self-transcendence in lung cancer patients and explore its risk factors,so as to provide a theoretical basis for clinical intervention decision-making.Methods 243 lung cancer patients who were admitted to the Department of Lung Cancer Center of West China Hospital,Sichuan University from September 2023 to February 2024 were enrolled as the study subjects;general infor-mation questionnaire,self-transcendence scale,Herth hope scale and social support scale were used for the investigation.The influencing factors related to self-transcendence of lung cancer patients were analyzed.Results The total mean score of self-transcendence in lung cancer patients was(44.73±8.94);the total mean score of hope level was(37.60±4.98),and the total mean score of social support was(41.31±7.27).Self-transcendence was positively correlated with hope level and social support(P＜0.001,P＜0.001).Education,hope level and social support were influencing factors of self-transcendence in lung cancer pa-tients(P＜0.05,P＜0.001,P＜0.05).Conclusion Self-transcendence in lung cancer patients was at a low level and was influenced by hope level and social support.Healthcare professionals should pay attention to improving the hope level of lung cancer pa-tients,carrying out targeted psychological interventions,and at the same time guiding them to enhance the perception of social support,so as to promote the realization of self-transcendence in patients.

Objective: To investigate the histopathological and immunohistochemical characteristics of benign apocrine cystic papillary hyperplasia of the breast with loss of myoepithelial cell layer. Methods: The clinical data, histopathological features and immunohistochemical profile of patients with benign apocrine cystic papillary hyperplasia of breast with loss of myoepithelial cell layer from January 2016 to December 2021 were examined, in which six patients were identified. Results: All six patients were female, aged 36-61 years (median 46 years), who presented with a breast mass; three cases were from the left breast and three cases were from the right breast. Microscopic examination of all cases showed breast hyperplasia with apocrine cysts, accompanied by different degrees of micropapillary and papillary hyperplasia of apocrine cells. One case was associated with lobular carcinoma in situ, and one case was associated with apocrine ductal carcinoma in situ with intraductal dissemination in adenosis. Immunohistochemical staining of CK5/6, p63, SMA, SMMHC, Calponin and CD10 showed complete absence of myoepithelial cell layer surrounding ducts in apocrine cystic papillary hyperplasia. Conclusions: The myoepithelial cells of apocrine cystic papillary hyperplasia of the breast may undergo abnormal changes and may even be completely lost. The diagnosis should be comprehensively considered along with cytomorphological and histological features to avoid overdiagnosis.

Surgery is the standard treatment for resectable non-small cell lung cancer (NSCLC). Neoadjuvant and adjuvant therapy have been widely used for preventing recurrence and metastasis. Immune checkpoint inhibitors (ICIs) have brought long-term survival benefits in advanced NSCLC and showed higher downstage rates and pathological remission in the neoadjuvant setting. Predictive biomarkers are of great significance to identify the beneficiaries of neoadjuvant ICIs. At present, the biomarkers are still inconclusive. We summarized the clinical trials of neoadjuvant immune checkpoint inhibitors that have been disclosed so far, and reviewed the progress of the biomarkers associated with those trials.

Objective:To investigate the therapeutic effect of dorsal skin-tightening technique on the correction of mild penile curvature in children with hypospadias.Methods:The clinical characteristics of hypospadias patients (95 cases) with mild penile curvature (<30°) after degloving penis during operation in our hospital from Jan 2017 to Sep 2020 were analyzed retrospectively. Group A: A new technique, reconstructing penile pubic angle at 12 o'clock position of penile dorsal side after degloving and suturing forskin outer and inner plate with tension at 12 o'clock position, was performed in dorsal skin-tightening group (43 cases). Gtoup B: while in dorsal midline tunica albuginea plication group (52 cases), Buck fascia was incised on dorsal midline area, following by tunica albuginea plication with one or two stitches. The patients in Group A were 0.4 to 1.5 years old, and the median age was 1.1 years, urethral orifice were located on distal shaft in 36 cases, proximal in 7 cases.The patients in Group B were 0.5 to 2.6 years old, and the median age was 1.5 years, urethral orifice were located on distal shaft in 41 cases, proximal in 11 cases. The penile ventral curvature degree was recorded during regular follow-up (postoperative 6 and 12 months), as well as postoperative complications.Results:Artificial erection test showed penile curvature was corrected during surgery by measuring with protractor. There was no chordee by measuring with the side photos in all patients during an average of 1.6 years follow-ups. There were 4 case of urethral fistula in Group B and 3 cases in Group A. No cases of urethrostenosis, diverticulum or concealed penis was recorded. The difference of postoperative complications had no statistical significance.Conclusion:Hypospadias with mild penile curvature could be effectively corrected by dorsal skin-tightening technique, which showed a good result of early follow-up.

BACKGROUND: Bronchial sleeve lobectomy is essential surgical approach to treat centralized lung cancer. It is the best reflected the principle of lung cancer surgery, "remove tumor completely while minimize pulmonary function loss". Bronchial pleural fistula (BPF) is not common but very severe complication of bronchial sleeve lobectomy, that is usually fatal. Present article is to explore clinical effect on prevention of bronchial pleural fistula (BPF) in bronchial sleeve lobectomy, by wrapping brachial anastomosis with pedicled pericardial fat flap. METHODS: Clinical data of 39 non-small cell lung cancer (NSCLC) patients who underwent surgical resection during January 2016 to May 2019 in Lung Cancer Center of West China Hospital, Sichuan University were collected and retrospectively analyzed. All of the patients underwent bronchial sleeve lobectomy and a brachial anastomosis wrapping with pedicled pericardial fat flap. RESULTS: All patients recovered well and were discharged within 6 d-14 d after operation. No BPF occurred, nor other severe complications, such as reoperation needing intrathoracic bleeding, several pneumonia and respiratory failure, and life threatening cardiac arrhythmia. Only one patient (1/39) had several anastomotic stenosis and consequential atelectasis of residual lung in operative side 6 months after surgery. CONCLUSIONS Wrapping bronchial anastomosis with pedicled pericardial fat flap in bronchial lobectomy for centralized NSCLC is a simple and effective approach to prevent BPF, thus safety of the operation could be significantly improved.

Objective To investigate the effect of a modified preputial flap urethroplasty in twostage treatment of severe hypospadias.Methods The clinical characteristics of the severe hypospadias patients (41 cases) who underwent the staged urethroplasty by using the procedure of preset urethral plate with preputial flap from January 2015 to December 2016 were analyzed retrospectively.We used a modified method (modified group,23 cases):Form the distal urethra with the transected distal urethral plate by using tubularize incised plate (TIP) procedure during the first stage operation,after completely straightened the penis,urethral plate was preseted with transverse preputial flap at the penis shaft.While in the traditional group (18 cases),urethral plate was preseted with preputial flap by using Bracka procedure after transecting urethral plate.The corresponding missing part of urethra underwent urethroplasty at the second stage operation six months later.The patients in the modified group were 9 to 18 months old,and the median age was 13 months;meatus were located at the penis shaft in 10 cases,scrotum in 12 cases,perineum in 1 case.The patients in the traditional group were 9 to 18 months old,and the median age was 13 months;meatus were located at the penis shaft in 6 cases,scrotum in 10 cases,and perineum in 2 cases.There was no statistic difference in age and meatus position between the two groups.Results During the first stage operation,distal urethra was repaired by 13-19 mm,with an average of (14.5 ± 1.3) mm,and the proximal urethra was repaired by 0-6 mm,with an average of (3.1 ± 2.4) mm at the modified group.While at the traditional group,the length of proximal urethra was repaired of 0-9 mm,with an average of (5.6:±:2.9) mm.The urethral length required for reconstruction was measured during the second stage operation,with an average of (26.3:t:4.4) mm in the modified group and (40.5 ± 3.3) mm in the traditional group (P ＜ 0.05).There were 3 case of urethral stricture after removed the catheter,with 2 cases in the modified group and 1 case in the traditional group.Postoperative follow-up was 2 to 3 years,with an average of 2.4 years.There were 3 cases (3/23,13.0％) of urethral fistula in the modified group and 3 cases (3/18,16.7％) in the traditional group.Ascended testis occured in 2 patients in the traditional group after operation.No case of urethrostenosis,diverticulum,chordee or concealed pennis was recorded.There was no significant difference in postoperative complications between the two groups (P ＞ 0.05).Conclusions The modified staged preputial flap method shorten the new forming urethra by making full use of its own materials at the second stage operation,which was helpful to reduce complications.

Objective: To evaluate the value of different sequences magnetic resonance imaging (MRI) in rectal cancer re-staging after neoadjuvant chemoradiation therapy (NCRT). Methods: The clinical data of 117 patients with rectal cancer who underwent NCRT before surgery operation in Peking University cancer hospital from January 2016 to December 2018 were retrospectively analyzed. Among 117 patients, 101 patients underwent MRI scanning before and after NCRT, and 16 patient underwent MRI scanning after NCRT; T₂ weighted imaging (T₂WI) and diffusion weighted imaging (DWI) scanning were performed in all patients, and dynamic contrast enhancement (DCE) scanning was performed in 96 patients. T₂WI, T₂WI combined with DWI, T₂WI combined with DCE were used for T re-staging of rectal cancer after NCRT respectively, and the results of which were compared with those of pathology after operation. Results: The sensitivity of diagnosis of ypT_0-2 rectal cancer after NCRT using T₂WI combined with DWI, T₂WI combined with DCE respectively was significantly higher than that using T₂WI: 52.7% (29/55) and 30.4% (14/46) vs. 10.9% (6/55), and there was statistical difference (P<0.05). The accuracy rate and specificity of diagnosis of ypT₃ and ypT₄ rectal cancer after NCRT using T₂WI combined with DWI were significantly higher than that using T₂WI, with an accuracy rate of 60.7% (71/117) vs. 47.0%(55/117) and 92.3% (108/117) vs. 80.3% (94/117), and a specificity of 55.9% (33/59) vs. 23.7% (14/59) and 92.9% (105/113) vs. 80.5% (91/113), and there were statistical differences (P<0.05). The accuracy rate of down-staging after NCRT using T₂WI combined with DWI was significantly higher than that using T₂WI: 72.3% (73/101) vs. 58.4% (59/101), and there was statistical difference (P<0.05); there was no significant difference in accuracy rate between using T₂WI and using T₂WI combined with DWI and between using T₂WI combined with DWI and using T₂WI combined with DCE (P > 0.05). Conclusions T₂WI combined with DWI is superior to T₂WI in re-staging of rectal cancer after NCRT.

Objective To investigate the application of pedicled tunica vaginalis flap cover new urethra in redo and second-stage hypospadias repair.Methods Retrospective analysis was performed in 45 redo hypospadias repair cases,aged from 1 year 3 months to 9 years 4 months (median 5 years 3month).All patients were divided into urethral dehiscence after hypospadias repair (group A) and the second stage surgery of two-stage hypospadias repair (group B) based on medical history.According to the site of dehiscence,the group A were further divided into midshaft urethral dehiscence (A1) and glans and distal urethral dehiscence with urethral opening located on midshaft (A2).After new urethra was completed,the appropriate size of the pedicledtunica vaginalis flap was transferred to cover the new urethra.Results There was no scrotal hematoma occurred in all 45 cases,and somecomplications occurred,including scrotal swelling in 1 case,high-riding testicle in 2 cases,penile clockwise torsion in 1 case,urethrocutaneous fistula in 6 cases.All the 45 cases were followed up for 1 to 4 years,with mean of 1.8 years.One more urethrocutaneous fistula occurred in group A2 and 1 more urethrocutaneous fistula with urethral stricture occurred in group B.There was no penile curvature and urethral diverticulum occurred in all cases.Conclusions Pedicled tunica vaginalis flap could be used as waterproofing layer to cover new urethra in redo hypospadias repair and presented a low incidence rate of postoperative complications.
