ABSTRACT
The STAR tool was used to evaluate and analyze the science, transparency, and applicability of Chinese pathology guidelines and consensus published in medical journals in 2022. There were a total of 18 pathology guidelines and consensuses published in 2022, including 1 guideline and 17 consensuses. The results showed that the guideline score was 21.83 points, lower than the overall guideline average (43.4 points). Consensus ratings scored an average of 27.87 points, on par with the overall consensus level (28.3 points). Areas that scored above the overall level were "conflict of interest" and "working groups", while areas that scored below the overall level were "proposals", "funding", "evidence", "consensus approaches" and "accessibility". To sum up, the formulation of pathology guidelines and consensuses in 2022 is not standardized, and the evidence retrieval process, evidence evaluation methods and grading criteria for recommendations on clinical issues are not provided in the formulation process; the process and method for reaching consensus are not provided, the plan is lacking, and registration is not carried out. It is therefore suggested that guidelines/consensus makers in the field of pathology should attach importance to evidence-based medical evidence, strictly follow guideline formulation methods and processes, further improve the scientific, applicable and transparent guidelines/consensuses in the field, and better provide support for clinicians and patients.

Pumonary salivary gland-type tumours (SGT) represent a small but distinct group of primary lung neoplasms. These types of tumours originate from the submucosal bronchial glands of the tracheobronchial tree. Pulmonary SGTs differ greatly in the incidence of individual tumours from salivary gland tumours of the head and neck. Additionally, the vast majority of pulmonary SGT are malignant. Recently, pathological diagnosis has significantly improved with the application of molecular diagnostic technologies. However, the current knowledge of benign SGTs is limited; moreover, tumour diversity and overlapping morphological features of SGT represent diagnostic challenges such as correct tumour categorisation and their accurate differentiation from malignant lesions. Compounding this inherent difficulty has been the recent introduction of new variants, including sialadenoma papilliferum (SP). Pulmonary SP is very rare, with limited reports available, and most of the initial diagnoses rendered so far were incorrect, resulting in inappropriate treatment. Several cases of SP have recently been reported. This review will serve to update practicing pathologists on the morphology, immunophenotype and molecular characteristics of SP and its mimics.

Objective: To investigate the relationship between micropapillary patten, cribriform pattern and retraction clefting of HPV associated endocervical adenocarcinoma and Silva classification and prognosis; and to validate the application and clinical significance of Silva system in endocervical adenocarcinoma. Methods: Cases of endocervical adenocarcinoma from January 2009 to November 2017 were selected from the Second Hospital of Jilin University and followed up. The morphologic characteristics of Silva classification, micropapillary patten, cribriform pattern and retraction clefting were observed and recorded. Inferential analysis was performed to compare clinicopathological variables data between pattern subgroups. Results: The study included 120 patients (ranging from 26 to 73 years) with an average age of (48.0±9.1)years. Silva A, B and C accounted for 9.2% (11/120), 18.3% (22/120) and 72.5% (87/120), respectively. Cases with micropapillary pattern accounted for 25.8%(31/120), of which six cases were Silva B and 25 cases were Silva C. Cases with cribriform pattern accounted for 53.3%(64/120), including three cases of Silva A, 17 cases of Silva B and 44 cases of Silva C. Retraction clefting occurred in 28.3%(34/120) cases, all were Silva C. The three morphologic features were associated with lymph node metastasis (P<0.05). Univariate analysis showed that micropapillary pattern was related to prognosis of endocervical carcinoma (P<0.05), while cribriform pattern, retraction clefting and Silva classification showed no correlation with overall survival and disease-free survival. Conclusions: The suggestion is revising the Silva C criteria by adding papillary patten and retraction clefting as factors and expanding the Silva pattern system to include more histologic variants. The Silva system is helpful to select appropriate operation before surgery, but its prognostic value requires further evaluation.

Objective: To summarize the etiologies of bilateral adrenal lesions and the changes of the disease profile in hospitalized patients. Methods: Bilateral adrenal lesion screening was conducted in all patients admitted to Peking University Third Hospital from 1994 to 2017. The etiologies and disease profiles of bilateral adrenal lesions were retrospectively analyzed. Results: A total of 260 patients with bilateral adrenal lesions were included in the study. There were 146 males and 114 females with a mean age of (55.4±16.2) years. The most common adrenal lesion was bilateral adrenal hyperplasia (75 cases, 28.8%), followed by bilateral adrenal adenomas (71 cases, 27.3%), metastatic carcinoma (51 cases, 19.6%), discordant bilateral adrenal lesions (27 cases, 10.4%), bilateral pheochromocytomas (13 cases, 5.0%), and others. The clear data of endocrine function evaluation could be found in 184 patients. Among them, 111 cases (60.3%) were nonfunctioning lessions, 34 cases (18.5%) with primary aldosteronism, 15 cases (8.1%) with pheochromocytoma, 13 cases (7.1%) with congenital adrenal hyperplasia, 6 cases (3.3%) with primary hypoadrenocorticism, and 5 cases (2.7%) with Cushing syndrome. Using every 8 years as a period of time, the number of hospitalized patients with bilateral adrenal lesions increased with years in three periods (8, 41 and 211 cases, respectively). Conclusions: The most common cause of bilateral adrenal lesions is adrenal hyperplasia in the hospitalized patients. More than half of bilateral adrenal lesions are nonfunctioning. In functional bilateral lesions, primary aldosteronism and pheochromocytoma account for a large proportion.

Objective: To evaluate the predictive value of 3 different risk stratification models including the risk adjustment in congenital heart surgery-1 (RACHS-1), Aristotle basic complexity (ABC), and Society of Thoracic Surgeons-European Association for cardiothoracic surgery congenital heart surgery mortality score (STAT) risk scoring system for death and major complications in patients after congenital heart surgeries. Methods: A total of 3 578 patients (age<18 years old) received surgery for congenital heart diseases from January to December 2015 in Fuwai hospital were enrolled, and the clinical data were retrospectively analyzed. The congenital heart disease patients were 1.7 (0.8, 4.5) years old, and the male accounted for 54.3% (1 943 cases).Death after surgery and major complications including use of extracorporeal membrane oxygenation, bedside thoracotomy, peritoneal dialysis for renal failure, bedside hemofiltration for renal failure, tracheotomy, reoperation for mediastinum infection, reoperation for heart in hospital were observed. The area under the receiver operating characteristic (ROC) curve was calculated to evaluate the predictive value for mortality after surgery and major complications with RACHS-1, ABC, and STAT risk scoring systems. Results: The mortality after surgery was 0.4% (14/3 578) , and the rate of major complications was 3.2% (113/3 578) . For mortality after surgery, areas under the ROC curve were 0.682 (95%CI 0.570-0.795, P=0.002), 0.722 (95%CI 0.612-0.832, P<0.001), and 0.753 (95%CI 0.659-0.847, P<0.001) with RACHS-1, ABC and STAT risk scoring systems, respectively. For major complications, areas under the ROC curve were 0.709 (95%CI 0.667-0.751, P<0.001), 0.743 (95%CI 0.702-0.784, P<0.001), and 0.731 (95%CI 0.693-0.770, P<0.001) with RACHS-1, ABC and STAT risk scoring systems, respectively. Conclusion: STAT risk scoring system is superior to RACHS-1 and ABC risk scoring systems on predicting death after surgery, and ABC risk scoring system is superior to RACHS-1 and STAT risk scoring systems on predicting major complications in Chinese patients with congenital heart disease in the single center.

Objective: To investigate the clinicopathologic features, molecular characteristics and prognosis of spread through air space (STAS) in patients with adenocarcinoma of the lung. Methods: Two hundred and eighty-eight lung adenocarcinoma patients with complete clinicopathologic and follow-up data were included. The patients were divided into STAS positive (178 cases) and negative (110 cases) groups.EGFR and KRAS gene mutations were detected by amplification refractory mutation system (ARMS), and ALK and ROS1 gene fusion were detected by fluorescence in situ hybridization method. The relationship between STAS and clinicopathologic, molecular features, and patient outcome was analyzed. Results: STAS was present in 61.8%(178/288) of lung adenocarcinomas. The positive rate of STAS in tumors >3 cm was significantly higher than that in tumors ≤3 cm (P=0.009), and was significantly higher in tumors with pleural invasion (P<0.01), venous invasion (P<0.01), lymphatic invasion (P<0.01), perineural invasion (P=0.029) and tumors with necrosis (P<0.01). STAS was also correlated with tumor recurrence (P<0.01) and advanced pathologic TNM stage (P=0.002). There was no significant correlation with patients' gender, age and smoking history. Histologically, STAS was present in 58.0%(91/157), 67.6%(50/74), 2/6, 64.3%(27/42) and 8/9 of acinar, papillary, lepidic, solid and micropapillary adenocarcinomas, respectively. In addition, the positive rates of STAS in tumor with micropapillary (>5%) and without micropapillary pattern were 80.9%(55/68) and 55.9%(123/220), respectively (P<0.01). STAS was significantly higher in EGFR negative group (P=0.034), ALK gene rearrangement group (P=0.003) and ROS1 gene rearrangement group (P=0.012), but there was no significant correlation with KRAS mutation. Univariate survival analysis showed that patients with STAS had a shorter progression-free survival (PFS, P<0.01) and overall survival (P=0.013). Multivariate analysis confirmed that STAS was an independent predictor of PFS in lung adenocarcinoma patients (HR: 2.749, 95%CI: 1.550-4.876, P=0.001). Conclusions: The presence of STAS in lung adenocarcinoma suggests high risk of recurrence and invasion and is thus an important prognostic factor. In addition, STAS is associated with EGFR mutation, ALK and ROS1 gene rearrangement.

OBJECTIVE: To observe the effect of transplantation of marrow mesenchymal stem cells (BMSCs) transfected with insulin-like growth factor-1 (IGF-1) on fracture healing of rats with diabetes and discuss the gene therapy for diabetic fracture. METHODS: 60 8-week-old male Wistar rats weighing 180-200 g were divided into the control group and experimental group at random. All of them suffered from right tibia fracture following the model of diabetes induced by streptozotocin. BMSCs were transfected with Ad- IGF-1 and BMSCs of the appropriate group were transplanted to part of the fracture area. 6 rats were selected from each group at 1, 2, 3, 5 and 7 weeks after the surgery. Local bone callus was stained with hematoxylin-eosin (H-E) and IGF-1 in the bone callus and serum was tested. RESULTS: Osteoid tissues formed at 3 weeks in the experimental group; mature lamellar bone formed at 7 weeks in the experimental group; fibrous bone callus was observed in the control group. IGF-1 in bone callus of the experimental group is increasing and significantly different from that of the control group (p < 0.05). Concentrations of IGF-1 in the serum of the two groups were increasing gradually from the first week. The control group reached its peak in the 5th week. The experimental group reached a high concentration in the 5th week and maintained a high concentration in the 7th week. The differences at various times between the two groups have statistical significance (p < 0.05). CONCLUSION: Transplantation of BMSCs transfected with IGF-1 gene can promote fracture healing of rats with diabetes (Tab. 4, Fig. 1, Ref. 20).
