Prostate cancer is a common malignant tumor in male genitourinary system, and radical prostatectomy is one of the important methods to treat prostate cancer. Indocyanine green is a non-radioactive, water-soluble compound, which can help identify anatomical structures and visualize blood vessels through near-infrared fluorescence. The role and injection techniques of Indocyanine green in radical prostatectomy in sentinel lymph node identification, pelvic lymph node dissection and neurovascular bundle preservation are reviewed, so as to provide a reference for improving the surgical effect, reducing the difficulty of surgery, and prolonging the survival period of patients, and evaluate the potential research field of this technology in the future.

Objective To explore the clinicopathological and immunohistochemical features of nephrogenic adenoma(NA).Methods Clinical data of NA patients diagnosed in the Department of Pathology,Zhongshan Hospital,Fudan University from July 2016 to October 2022 were collected and analyzed to explore their clinicopathological features.Results A total of 13 NA cases were enrolled.There were 11 males and 2 females.Organs involved:ureter(n=7),bladder(n=5),bladder and ureter(n=1),renal pelvis(n=2).NA patients performed as ureteral stenosis(6/7),rough bladder wall(3/5),and renal pelvis polyp(2/2).The typical microscopical features of NA were tubular(13/13)and papillary(4/13)structures,covered with cuboidal or columnar epithelium(13/13),or a mixed hobnail-spike eosinophilic epithelium(12/13);the interstitium was loose,containing varied amounts of vasculature and inflammatory cells(13/13).Immunohistochemistry revealed specific expressions of CK7,PAX-8,CK19 and CK8.Conclusions NA is a rare neoplasm of the urinary system with unique histological features.NA has the risk of misdiagnosis and over-treatment,and the potential of recurrence and malignant conversion.The diagnosis of NA depends on pathology,and the immunohistochemistry can be helpful for its pathological diagnosis.

The patient, an 84-year-old man, was admitted to the hospital with "low back pain with limitation of movement for more than half a year". Admission examination: mild kyphotic deformity of the spine, significant tenderness and percussion pain in the lower back, bilateral lower limb muscle strength graded 5, normal skin sensation. Lumbar MRI and CT revealed a compressive fracture of the L 4 vertebra. Dual-energy X-ray absorptiometry (DEXA) indicated a bone mineral density T-score of -2.6, suggesting osteoporosis. Admission diagnosis: osteoporotic compressive fracture of the L 4 vertebra. The patient underwent thorough examinations to exclude surgical contraindications. On the fourth day of admission, the patient underwent percutaneous vertebroplasty of the L 4 vertebra. At the end of the operation, the patient became unresponsive, with a blood pressure drop to 94/63 mmHg and oxygen saturation falling to 80%. Cranial CT showed multiple punctate gas density shadows within the brain. Lumbar CT revealed gas accumulation in the soft tissue adjacent to the lumbar spinous processes, localized intraductal gas, and punctate gas density shadows within the vessels in both groin areas. The diagnosis was intracranial arterial gas embolism. The patient's condition deteriorated further, with loss of consciousness, neck stiffness, increased muscle tone of both lower limbs, and positive Babinski's sign on both sides. Symptomatic treatments included brain protection, maintaining cerebral perfusion, and improving collateral cerebral circulation, but the patient did not regain consciousness. The patient developed a pulmonary infection one month postoperatively and died three months postoperatively due to respiratory failure. This case highlights the potential risk of gas embolism during vertebroplasty. Measures to reduce such complications should be implemented, such as minimizing the duration of venous blood-air contact, pre-filling the cannula with saline to reduce the venous blood-air interface, and appropriately increasing venous pressure to reduce the risk of gas entry. It is recommended to use smaller diameter catheters. For patients with pre-existing cardiac conditions or elderly patients, preoperative cardiac Doppler ultrasound should be performed to exclude anatomical abnormalities such as patent foramen ovale.

Electroacupuncture treatment of primary insomnia is widely used and with confirmed efficacy. The factors influencing the therapeutic effect of electroacupuncture include waveform selection, treatment frequency, stimulation intensity, stimulation time and acupoint selection. The mechanism of electroacupuncture in treating this disease mainly includes regulating the levels of excitatory neurotransmitters, γ-aminobutyric acid, melatonin and interleukin cytokines.

Objective:To identify the risk factors for simple congenital ptosis.Methods:A case-control study was performed.A total of 106 children diagnosed with simple congenital ptosis at the Second Affiliated Hospital of Zhejiang University School of Medicine from October 2018 to January 2021 were recruited as a case group, and 106 sex-matched children without congenital abnormalities were enrolled as a control group at the same period.Ophthalmic examinations, including interpalpebral fissure height and margin reex distance 1, were performed on all participants.A questionnaire survey was administered to their mothers.The questionnaire included demographic information, prenatal maternal diseases, medical treatments and environmental exposures during pregnancy.Univariate analysis was used to compare the differences in variables between the case and control groups.Variables with P<0.20 were retained for multivariate logistic regression analysis to identify the risk factors for simple congenital ptosis.The goodness of fit of the model was evaluated by the Hosmer-Lemeshow test, and collinearity was assessed by the variance inflation factor (VIF). This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of the Second Affiliated Hospital of Zhejiang University School of Medicine (No.2019-136). The method and purpose of the study were fully explained to the children's guardians and written informed consent was obtained. Results:Comparisons of gestational age <37 weeks, birth order ≥2, maternal age, antibiotic use in the first trimester, paternal smoking ≥half a pack per day, and prenatal maternal passive smoking between the two groups were all with P<0.20.Multivariate logistic regression analysis showed that gestational age <37 weeks (odds ratio [ OR]=4.58; 95% confidence interval [ CI]: 1.24-16.85), paternal smoking ≥half a pack per day ( OR=2.28; 95% CI: 1.22-4.28) and prenatal maternal passive smoking ( OR=3.13; 95% CI: 1.16-8.41) were risk factors for simple congenital ptosis.No significant collinearity was found among these identified factors (all VIF<5). Conclusions:Preterm birth, paternal smoking, and prenatal maternal passive smoking are risk factors for simple congenital ptosis.

Objective:To establish and evaluate a nomogram for long-term survival of patients with intrahepatic cholangiocarcinoma (ICC) after radical resection.Methods:The data of ICC patients who underwent radical resection for the first time at Zhongshan Hospital, Fudan University from January 2014 to December 2017 were retrospectively analyzed. Of 167 patients who were enrolled, there were 104 males and 63 females, with the age of (60.3±10.9) years. Tumor tissues were collected for immunohistochemical staining and interpretation. Univariate Cox regression, LASSO regression and multivariate Cox regression were used to analyze influencing factors of postoperative long-term survival after ICC. R software was used to construct a nomogram in predicting ICC prognosis.Results:Cox regression analysis showed that TNM staging, poorly differentiated tumor, positive resection margin, positive mucin 5 expression and abnormal P53 expression to be independent risk factors associated with poor long-term survival after radical resection. The prognostic nomogram model of ICC was constructed based on these factors. The C-index was 0.821. The nomogram model consistency index had a high degree of prognostic differentiation. The 45° diagonal of the 3-year postoperative calibration curve which represented the actual survival fitted well with the segmented line which represented the predicted survival of the nomogram. The area under the receiver operating characteristic curve of the nomogram model was higher than that of AJCC TNM staging (0.894 vs. 0.803, z=4.10, P<0.001). The nomogram model was more effective in predicting postoperative survival of ICC patients than the TNM staging. Conclusion:TNM staging, poorly differentiated tumor, positive resection margin, positive mucin 5 expression and abnormal P53 expression were independent risk factors for postoperative survival of ICC. The nomogram model could better evaluate long-term prognosis of ICC patients after radical resection than the traditional TNM staging system.

Cancer pain is one of the main symptoms of patients suffering from malignant tumors. If it is not timely treated, it will lead to refractory pain and increase the burden on both the individuals and society. In China, the program titled" Good Pain Management" has been carried out for nearly 7 years, which increases the overall assessment and treatment levels for cancer pain among medical personnel. Nevertheless, the clinical efficacy for cancer pain treatment is not satisfactory. As an important treatment for malignant tumors, radiation therapy is also one of the main methods for treating cancer pain. For the first time, we proposed the concept of " peri-radiotherapeutic period" , and emphasized the continuous analgesic treatment for patients with cancer pain before, during and after radiotherapy. In this article, current status of cancer pain treatment at home and abroad was illustrated, and standardized assessment and management of cancer pain during the " peri-radiotherapeutic period" were summarized.

This corrects the article “Analysis of Tau Protein Expression in Predicting Pathological Complete Response to Neoadjuvant Chemotherapy in Different Molecular Subtypes of Breast Cancer” in volume 23 on page 47.This article was initially published on the Journal of Breast Cancer with a misspelled the abbreviation in figure 3. The abbreviation ‘HP’ should be corrected as ‘HR’.

PURPOSE: Tau is a microtubule-associated protein that can be found in both normal and abnormal breast cells. Whether the expression of Tau protein can predict the response to neoadjuvant chemotherapy (NACT) is still unclear. In this study, we assessed the role of Tau protein expression in predicting a pathological complete response (pCR) to NACT for different subtypes of breast cancer. METHODS: Four hundred and sixty-eight eligible patients were retrospectively recruited in our study. The relationship between clinicopathologic factors, including Tau protein expression, and pCR in different subtypes was evaluated using logistic regression analysis. Correlation between Tau and disease-free survival (DFS) and overall survival (OS) was performed using Kaplan–Meier analysis. RESULTS: The expression of Tau protein was negatively correlated with pCR, especially in triple-negative breast cancer (TNBC). No significant difference was observed in the luminal human epidermal growth factor receptor-2 (HER2)-negative subtype and HER2-positive subtype. Patients with pCR were associated with better DFS and OS (p < 0.05). However, Tau protein expression had no association with either DFS or OS (p > 0.05). CONCLUSION Tau protein expression can predict pCR before NACT in TNBC, but there was no correlation between Tau expression and DFS or OS.
