Abstract
Objective: To compare the short-term efficacy of Kamikawa anastomosis and double-tract reconstruction (DTR) after proximal gastrectomy. Methods: This was a propensity score matched, retrospective, cohort study. Inclusion criteria comprised age 20-70 years, diagnosis of gastric cancer by pathological examination of preoperative endoscopic biopsies, tumor diameter ≤4 cm, and location in the upper 1/3 of the stomach (including the gastroesophageal junction), and TNM stage IA, IB, or IIA. The study cohort comprised 73 patients who had undergone laparoscopic proximal gastric cancer radical surgery in the Department of Gastroenterology, Tangdu Hospital, Air Force Medical University between June 2020 and February 2023, 19 of whom were in the Kamikawa group and 54 in the DTR group. After using R language to match the baseline characteristics of patients in a ratio of 1:2, there were 17 patients in the Kamikawa group and 34 in the DTR group. Surgery-related conditions, postoperative quality of life, and postoperative complications were compared between the two groups. Results: After propensity score matching, there were no statistically significant differences in baseline data between the two groups (P>0.05). Compared with the DTR group, the Kamikawa group had longer operative times (321.5±15.7 minutes vs. 296.8±26.1 minutes, t=32.056, P<0.001), longer anastomosis times (93.0±6.8 minutes vs. 45.3±7.7 minutes, t=56.303, P<0.001), and less bleeding (76 [54~103] mL vs.112 [82~148) mL, Z=71.536, P<0.001); these differences are statistically significant. There were no statistically significant differences between the two groups in tumor size, time to first postoperative passage of gas, postoperative hospital stay, number of lymph nodes removed, duration of lymph node dissection, or total hospitalization cost (all P>0.05). The median follow-up time was 6.1 ± 1.8 months. As to postoperative quality of life, the Kamikawa group had a lower rate of upper gastrointestinal contrast reflux than did the DTR group (0 vs. 29.4% [10/34], χ2=6.220, P=0.013); this difference is statistically significant. However, differences between the two groups in quality of life score on follow-up of 3 months and 6 months on the Gastroesophageal Reflux Disease (GERD) scale were not statistically significant (all P>0.05). The incidence of postoperative complications was 2/17 in the Kamikawa group, which is significantly lower than the 41.2% (14/34) in the DTR group (χ2=4.554, P=0.033). Conclusion: Kamikawa anastomosis and DTR are equally safe and effective procedures for reconstructing the digestive tract after proximal gastric surgery. Although Kamikawa anastomosis takes slightly longer and places higher demands on the surgical team, it is more effective at preventing postoperative reflux.

Abstract
Schrödinger cat states, quantum superpositions of macroscopically distinct classical states, are an important resource for quantum communication, quantum metrology and quantum computation. Especially, cat states in a phase space protected against phase-flip errors can be used as a logical qubit. However, cat states, normally generated in three-dimensional cavities and/or strong multi-photon drives, are facing the challenges of scalability and controllability. Here, we present a strategy to generate and preserve cat states in a coplanar superconducting circuit by the fast modulation of Kerr nonlinearity. At the Kerr-free work point, our cat states are passively preserved due to the vanishing Kerr effect. We are able to prepare a 2-component cat state in our chip-based device with a fidelity reaching 89.1% under a 96 ns gate time. Our scheme shows an excellent route to constructing a chip-based bosonic quantum processor.

Abstract
Objective: To analyze the clinical features, efficacy and prognosis factors of core binding factor (CBF) acute myeloid leukemia (AML) children in South China. Methods: This was a retrospective cohort study. Clinical data of 584 AML patients from 9 hospitals between January 2015 to December 2020 was collected. According to fusion gene results, all patients were divided into two groups: CBF-AML group (189 cases) and non-CBF-AML group (395 cases). CBF-AML group were divided into AML1-ETO subgroup (154 cases) and CBFβ-MYH11 subgroup (35 cases). Patients in CBF-AML group chosen different induction scheme were divided into group A (fludarabine, cytarabine, granulocyte colony stimulating factor and idarubicin (FLAG-IDA) scheme, 134 cases) and group B (daunorubicin, cytarabine and etoposide (DAE) scheme, 55 cases). Age, gender, response rate, recurrence rate, mortality, molecular genetic characteristics and other clinical data were compared between groups. Kaplan-Meier method was used for survival analysis and survival curve was drawn. Cox regression model was used to analyze prognostic factors. Results: A total of 584 AML children were diagnosed, including 346 males and 238 females. And a total of 189 children with CBF-AML were included, including 117 males and 72 females. The age of diagnosis was 7.3 (4.5,10.0)years, and the white blood cell count at initial diagnosis was 21.4 (9.7, 47.7)×109/L.The complete remission rate of the first course (CR1) of induction therapy, relapse rate, and mortality of children with CBF-AML were significantly different from those in the non-CBF-AML group (91.0% (172/189) vs. 78.0% (308/395); 10.1% (19/189) vs. 18.7% (74/395); 13.2% (25/189) vs. 25.6% (101/395), all P<0.05). In children with CBF-AML, the CBFβ-MYH11 subgroup had higher initial white blood cells and lower proportion of extramedullary invasion than the AML1-ETO subgroup, with statistical significance (65.7% (23/35) vs. 14.9% (23/154), 2.9% (1/35) vs. 16.9% (26/154), both P<0.05). AML1-ETO subgroup had more additional chromosome abnormalities (75/154), especially sex chromosome loss (53/154). Compared with group B, group A had more additional chromosome abnormalities and a higher proportion of tumor reduction regimen, with statistical significance (50.0% (67/134) vs. 29.1% (16/55), 34.3% (46/134) vs. 18.2% (10/55), both P<0.05). Significant differences were found in 5-years event free survival (EFS) rate and 5-year overall survival (OS) rate between CBF-AML group and non-CBF-AML group ((77.0±6.4)%vs. (61.9±6.7)%,(83.7±9.0)%vs. (67.3±7.2)%, both P<0.05).EFS and OS rates of AML1-ETO subgroup and CBFβ-MYH11 subgroup in children with CBF-AML were not significantly different (both P>0.05). Multivariate analysis showed in the AML1-ETO subgroup, CR1 rate and high white blood cell count (≥50×109/L) were independent risk factors for EFS (HR=0.24, 95%CI 0.07-0.85,HR=1.01, 95%CI 1.00-1.02, both P<0.05) and OS (HR=0.24, 95%CI 0.06-0.87; HR=1.01, 95%CI 1.00-1.02; both P<0.05). Conclusions: In CBF-AML, AML1-ETO is more common which has a higher extramedullary involvement and additional chromosome abnormalities, especially sex chromosome loss. The prognosis of AML1-ETO was similar to that of CBFβ-MYH11. The selection of induction regimen group FLAG-IDA for high white blood cell count and additional chromosome abnormality can improve the prognosis.

Abstract
A series of pleuromutilin derivatives containing an oxazolidinone skeleton were synthesized and evaluated in vitro and in vivo as antibacterial agents. Most of the synthesized derivatives exhibited potent antibacterial activities against three strains of Staphylococcus aureus (including MRSA ATCC 33591, MRSA ATCC 43300, and MSSA ATCC 29213) and two strains of Staphylococcus epidermidis (including MRSE ATCC 51625 and MSSE ATCC 12228). Compound 28 was the most active antibacterial agent in vitro (MIC = 0.008-0.125 μg·mL-1) and exhibited a significant bactericidal effect, low cytotoxicity, and weak inhibition (IC50 = 20.66 μmol·L-1) for CYP3A4, as well as exhibited less possibility to cause bacterial resistance. Furthermore, in vivo activities indicated that the compound was effective in reducing MRSA load in a murine thigh infection model. Moreover, it clearly facilitated the healing of MRSA skin infection and inhibited the secretion of the TNF-α, IL-6, and MCP-1 inflammatory factors in serum. These results suggest that oxazolidinone pleuromutilin is a promising therapeutic candidate for drug-resistant bacterial infections.

Abstract
Objective: To investigate the safety and feasibility of using an endoscopic suturing instrument in laparoscopic gastrojejunostomy. Methods: A descriptive case series study was conducted to retrospectively analyze the clinical data of 5 patients with gastric cancer who underwent laparoscopic distal gastrectomy (Billroth II + Braun anastomosis) at Tangdu Hospital, Air Force Medical University from October 2022 to January 2023. The common opening was closed using an endoscopic suturing instrument. The indications were as follows: (1) patients aged between 18 and 80 years; (2) patients with gastric adenocarcinoma; (3) cTNM between I-III; (4) lower-third gastric cancer and radical gastrectomy is recommended; (5) no history of upper abdominal surgery (except for laparoscopic cholecystectomy). The surgery was performed as follows: A side-to-side gastrojejunostomy was performed with endoscopic linear cutter stapler. Then the common opening was closed with endoscopic suturing instrument. During suturing and closing the common opening, a vertical mattress suture was used to completely invert and close the mucosa-to-mucosa and serosa-to-serosa of the gastric and jejunum walls. After the first layer of suture was completed, the seromuscular layer was sutured from top to bottom to embed the common opening of stomach and jejunum. Results: Laparoscopic closure of the common gastrojejunal opening with endoscopic suturing instrument was successfully completed in all 5 patients. The operative time was (308.6±22.6) minutes, while the time of gastrojejunostomy was (15.4±3.1) minutes. The operative blood loss was (34.0±10.8) ml. No intraoperative or postoperative complications occurred in any of the patients. The first passage of gas occurred at (2.6±0.9) days, and the postoperative hospital stay was (7.0±1.9) days. Conclusion: The application of endoscopic suturing instrument in laparoscopic gastrojejunostomy is safe and feasible.

Abstract
Spiroindolizidine oxindoles represent a kind of privileged scaffold in many biologically active natural alkaloids. 2,3-Dihydrobenzofuran derivatives exhibit significant bioactivities in a variety of pharmaceuticals. Herein, we assembled these two privileged fragments into a small molecule via double-dearomative [3 + 2] cycloadditions with pyridinium ylides and 2-nitrobenzofurans. This protocol features remarkable advantages including wide substrate scope, mild condition, high level of diastereoselectivities and yields. Thus, a collection of spiroindolizidine-fused dihydrobenzofurans/indolines were facilely produced efficiently.

Abstract
Abstract
The human heart is composed of various cell types with distinct embryonic origins and functions. Having an understanding of the components of the developing heart at a molecular level should provide better insights into its function in health and disease. Current single cell studies of human fetal hearts are limited by low cell numbers and poor cell type resolution. Here, we aimed to increase the number of cells studied while adding a spatial resolution. We analysed human hearts aged between post conception weeks of 8 and 11, where apex and base in each were processed, providing spatial resolution on cells constituting the myocardium and the great vessels. Our analysis suggests 6 main cell types in the developing hearts with a total of 28 subtypes and provides a differential expression signature for similar cell types with different origins and anatomical locations, including the smooth muscle cells and endothelial cells of the myocardium and the great vessels. Through immunohistochemistry, we validated our findings on these subtypes, as well as on the cells that were less clearly described before, such sinoatrial node cells or resident macrophages. Cell to cell interaction analysis inferred distinct molecular crosstalk across subtypes, including the cells of the great vessels or the vessels of the myocardium. Our findings suggest a list of transcription factors that might be involved in governing the identity of these cells. Collectively, our analysis provides a better understanding of human heart development, and will inform studies into disease modelling and disease progression.

Abstract
Objective: Currently, the Overlap anastomosis is one of the most favored reconstruction methods of intracorporeal esophagojejunostomy (EJS). Despite many advantages of the method, it remains some shortcomings to be improved when it comes to the retraction of the esophagus stump, the insertion of the anvil fork of the linear stapler into a "pseudo" lumen, and the closure of the common entry hole. This study aims to investigate the safety and feasibility of a multi-mode modified Overlap anastomosis. Methods: A descriptive case series study was conducted. Medical records of 152 consecutive patients who underwent totally laparoscopic total gastrectomy (TLTG) with our multi-mode modified Overlap EJS method by the same surgical team at our department from February 2017 to June 2020 were retrospectively analyzed. The multi-mode modified Overlap method mainly included (1) After ensuring the safety of tumor resection margin (proximal margin was at least 3 cm from the tumor), the esophagus was partially transected from left to right (with 5-8 mm width esophagus continuation). The specimen was then placed in a plastic bag which was tied up at the mouth using strings with a part of the esophageal wall poking through. Then the plastic bag containing the specimen was transferred to the right lumbar region, while the patient's body position was adjusted so that the abdominal esophagus could be pulled by the gravity of the specimen. (2) Using the "three-direction traction" method. The esophageal lumen was properly exposed, then guided by the gastric tube, the anvil fork was accurately placed into the esophageal lumen for completing the side-to-side EJS. (3) The 3-0 barbed suture was used in the closure of the common entry hole of the stapler from dorsally to ventrally with simple one-layer continuous suture (the stitch going from inside to inside) followed by continuous Lembert's suture (the stitch going from outside to outside). Combined with clinicopathological characteristics, the perioperative outcomes and postoperative complications of the whole group were analyzed and evaluated. Results: The study cohort included 129 men and 23 women, with a mean age of (60.2±9.1) years and a mean body mass index (BMI) of (23.2±3.1) kg/m(2). Of the 152 patients, 23 patients (15.1%) had a history of previous abdominal surgery; dentate line was invaded by tumor in 21 patients (13.8%). The mean length of the proximal resection margin was (3.3±0.3) cm and the postoperative pathological examination indicated negative resection margin tumor. The mean operative time and anastomotic time were (302.1±39.9) minutes and (29.8±5.4) minutes, respectively. The mean estimated blood loss was (87.9±46.4) ml. The mean length of postoperative hospital stay was (12.3±7.3) days. The overall severe postoperative complications (Clavien-Dindo ≥ II) occurred in 22 patients (14.5%). Six cases of pancreatic leakage were successfully recovered by adequate drainage, inhibition of pancreatic exocrine secretion and nutritional support. Ten cases of pneumonia and three cases of abdominal infection were cured with anti-infection and physical therapy. Two patients developed anastomotic leakage postoperatively. One case was caused by excessive tension of the Roux loop of the jejunum and excessive opening on the side of the jejunum after side-to-side anastomosis, and the other case was caused by an accidental intraoperative occurrence of "nasogastric tube stapled to the side-to-side anastomosis". Both of them recovered after conservative treatment including adequate drainage, anti-infection, and adequate nutritional support. One patient underwent immediate open surgery because of Peterson's hernia 7 days after TLTG, and the patient died due to extensive small bowel necrosis. Conclusions: Multi-mode modified overlap method simplifies the operation and reduces the difficulty of EJS. It is a safe and feasible method for EJS.

Abstract
With the development of instrument, equipment and surgical skills, especially the emergence of a series of high-level medical evidence, the laparoscopic techniques in the field of gastric surgery has been further expanded. Totally laparoscopic total gastrectomy (TLTG) has certain technical difficulties, and more challenges are reflected in the digestive tract reconstruction. The use of linear staplers has reduced the difficulty of digestive tract reconstruction to a certain extent and has strongly promoted the transition from laparoscopic-assisted total gastrectomy to TLTG. However, for TLTG, there are still many details that should be carefully concerned, so as to effectively avoid the surgical pitfalls and ensure the fluency and safety of the procedure. In this article, we discuss the surgical details based on our own experiences, including how to obtain surgical field exposure well, how to manage specific accidents when using linear stapler for esophagojejunostomy, how to prevent intra-abdominal hernias and Roux stasis syndrome, and how to prevent the stapled lines of the esophageal or jejunal stumps from direct contact with aorta.

Abstract
OBJECTIVE To analyze the composition of prostatic calculus in patients with BPH and explore its pathogenic factors and histopathological characteristics. METHODS Strictly following the inclusion and exclusion criteria, we included in this retrospective study 580 cases of bipolar transurethral plasma kinetic prostatectomy (TUPKP) performed in our hospital from May 2015 to May 2019, analyzed the histopathological and calculus-composition features of the patients with BPH complicated by prostatic calculi (the BPH+PC group) and the histopathological data of those with BPH only (the BPH group). We compared the related factors between the two groups of patients and performed uni- and multivariate logistic regression analyses of the data on those in the BPH+PC group. RESULTS The incidence rate of chronic inflammation was significantly higher in the BPH+PC than in the BPH group (83.1% vs 61.1%, P < 0.05), 90% of the cases moderate to severe and 81% with inflammatory cells mainly distributed in the prostate gland in the BPH+PC group, and 74% with inflammatory cells chiefly distributed in the prostate gland and stroma in the BPH group, with statistically significant difference between the two groups (P < 0.05). Prostatic calculi were found in 302 (52.1%) of the patients, including 71 cases of simple calculi (23.5%) and 231 cases of mixed calculi (76.5%). As for the chemical composition, calcium oxalate was detected in 212 cases (70.2%), carbonate apatite in 206 (68.2%), magnesium ammonium phosphate in 158 (52.3%), and uric acid calculi in 19 (6.3%). The calculus composition was not correlated with the age of the patients. There were statistically significant differences between the two groups of patients in age, prostate volume and IPSS (P < 0.05), but not in the PSA level, postvoid residual urine volume (PRV) or maximum urinary flow rate (Qmax) (P > 0.05). Logistic regression analyses showed that prostatic calculus was significantly correlated with chronic inflammation of the prostate, the patient's age and IPSS (P < 0.05) but not with the PSA level, PRV or Qmax (P > 0.05). CONCLUSIONS Prostatic calculus has a high incidence in BPH patients and varies widely in composition, chiefly consisting of calcium oxalate and carbonate apatite. The major factors contributing to prostatic calculi include chronic inflammation of the prostate (primarily the severe type), age and BPH. Prostate calculi may aggravate lower urinary tract symptoms, especially urinary storage symptoms, in patients with BPH, but not significantly affect the PSA level.?.

Abstract
Objective: To explore the effect of perioperative chemotherapy on the prognosis of gastric cancer patients under real-world condition. Methods: A retrospective cohort study was carried out. Real world data of gastric cancer patients receiving perioperative chemotherapy and surgery + adjuvant chemotherapy in 33 domestic hospitals from January 1, 2014 to January 31, 2016 were collected. Inclusion criteria: (1) gastric adenocarcinoma was confirmed by histopathology, and clinical stage was cT2-4aN0-3M0 (AJCC 8th edition); (2) D2 radical gastric cancer surgery was performed; (3) at least one cycle of neoadjuvant chemotherapy (NAC) was completed; (4) at least 4 cycles of adjuvant chemotherapy (AC) [SOX (S-1+oxaliplatin) or CapeOX (capecitabine + oxaliplatin)] were completed. Exclusion criteria: (1) complicated with other malignant tumors; (2) radiotherapy received; (3) patients with incomplete data. The enrolled patients who received neoadjuvant chemotherapy and adjuvant chemotherapy were included in the perioperative chemotherapy group, and those who received only postoperative adjuvant chemotherapy were included in the surgery + adjuvant chemotherapy group. Propensity score matching (PSM) method was used to control selection bias. The primary outcome were overall survival (OS) and progression-free survival (PFS) after PSM. OS was defined as the time from the first neoadjuvant chemotherapy (operation + adjuvant chemotherapy group: from the date of operation) to the last effective follow-up or death. PFS was defined as the time from the first neoadjuvant chemotherapy (operation + adjuvant chemotherapy group: from the date of operation) to the first imaging diagnosis of tumor progression or death. The Kaplan-Meier method was used to estimate the survival rate, and the Cox proportional hazards model was used to evaluate the independent effect of perioperative chemo therapy on OS and PFS. Results: 2 045 cases were included, including 1 293 cases in the surgery+adjuvant chemotherapy group and 752 cases in the perioperative chemotherapy group. After PSM, 492 pairs were included in the analysis. There were no statistically significant differences in gender, age, body mass index, tumor stage before treatment, and tumor location between the two groups (all P>0.05). Compared with the surgery + adjuvant chemotherapy group, patients in the perioperative chemotherapy group had higher proportion of total gastrectomy (χ(2)=40.526, P<0.001), smaller maximum tumor diameter (t=3.969, P<0.001), less number of metastatic lymph nodes (t=1.343, P<0.001), lower ratio of vessel invasion (χ(2)=11.897, P=0.001) and nerve invasion (χ(2)=12.338, P<0.001). In the perioperative chemotherapy group and surgery + adjuvant chemotherapy group, 24 cases (4.9%) and 17 cases (3.4%) developed postoperative complications, respectively, and no significant difference was found between two groups (χ(2)=0.815, P=0.367). The median OS of the perioperative chemotherapy group was longer than that of the surgery + adjuvant chemotherapy group (65 months vs. 45 months, HR: 0.74, 95% CI: 0.62-0.89, P=0.001); the median PFS of the perioperative chemotherapy group was also longer than that of the surgery+adjuvant chemotherapy group (56 months vs. 36 months, HR=0.72, 95% CI:0.61-0.85, P<0.001). The forest plot results of subgroup analysis showed that both men and women could benefit from perioperative chemotherapy (all P<0.05); patients over 45 years of age (P<0.05) and with normal body mass (P<0.01) could benefit significantly; patients with cTNM stage II and III presented a trend of benefit or could benefit significantly (P<0.05); patients with signet ring cell carcinoma benefited little (P>0.05); tumors in the gastric body and gastric antrum benefited more significantly (P<0.05). Conclusion: Perioperative chemotherapy can improve the prognosis of gastric cancer patients.

Abstract
Objective: To develop a convolutional neural network based model for assisting pathological diagnoses on thyroid liquid-based cytology specimens. Methods: Seven-hundred thyroid TCT slides were collected, scanned for whole slide imaging (WSI), and divided into training and test sets after labeling the correct diagnosis (benign versus malignant). The extracted regions of interest after noise filtering were cropped into pieces of 512 × 512 patch on 10 × and 40 × magnifications, respectively. A classification model was constructed using deeply learning algorithms, and applied to the training set, then automatically tuned in the test set. After data enhancement and parameters optimization, accuracy, sensitivity, specificity, positive predictive value and negative predictive value of the model were calculated. Results The training set with 560 WSI contained 4 926 cell clusters (11 164 patches), while the test set with 140 WSI contained 977 cell clusters (1 402 patches). YOLO network was selected to establish a detection model, and ResNet50 was used as a classification model. With 40 epochs training, results from 10× magnifications showed an accuracy of 90.01%, sensitivity of 89.31%, specificity of 92.51%, positive predictive value of 97.70% and negative predictive value of 70.82%. The area under curve was 0.97. The average diagnostic time was less than 1 second. Although the model for data of 40× magnifications was very sensitive (98.72%), but its specificity was poor, suggesting that the model was more reliable at 10× magnification. Conclusions: The performance of a deep-learning based model is equivalent to pathologists' diagnostic performance, but its efficiency is far beyond. The model can greatly improve consistency and efficiency, and reduce the missed diagnosis rate. In the future, larger studies should have more morphology diversity, improve model's accuracy and eventually develop a model for direct clinical use.

Abstract
Objective: Surgical site infection (SSI) can markedly prolong postoperative hospital stay, aggravate the burden on patients and society, even endanger the life of patients. This study aims to investigate the national incidence of SSI following abdominal surgery and to analyze the related risk factors in order to provide reference for the control and prevention of SSI following abdominal surgery. Methods: A multicenter cross-sectional study was conducted. Clinical data of all the adult patients undergoing abdominal surgery in 68 hospitals across the country from June 1 to 30, 2020 were collected, including demographic characteristics, clinical parameters during the perioperative period, and the results of microbial culture of infected incisions. The primary outcome was the incidence of SSI within postoperative 30 days, and the secondary outcomes were ICU stay, postoperative hospital stay, cost of hospitalization and the mortality within postoperative 30-day. Multivariable logistic regression was used to analyze risk factors of SSI after abdominal surgery. Results: A total of 5560 patients undergoing abdominal surgery were included, and 163 cases (2.9%) developed SSI after surgery, including 98 cases (60.1%) with organ/space infections, 19 cases (11.7%) with deep incisional infections, and 46 cases (28.2%) with superficial incisional infections. The results from microbial culture showed that Escherichia coli was the main pathogen of SSI. Multivariate analysis revealed hypertension (OR=1.792, 95% CI: 1.194-2.687, P=0.005), small intestine as surgical site (OR=6.911, 95% CI: 1.846-25.878, P=0.004), surgical duration (OR=1.002, 95% CI: 1.001-1.003, P<0.001), and surgical incision grade (contaminated incision: OR=3.212, 95% CI: 1.495-6.903, P=0.003; Infection incision: OR=11.562, 95%CI: 3.777-35.391, P<0.001) were risk factors for SSI, while laparoscopic or robotic surgery (OR=0.564, 95%CI: 0.376-0.846, P=0.006) and increased preoperative albumin level (OR=0.920, 95%CI: 0.888-0.952, P<0.001) were protective factors for SSI. In addition, as compared to non-SSI patients, the SSI patients had significantly higher rate of ICU stay [26.4% (43/163) vs. 9.5% (514/5397), χ(2)=54.999, P<0.001] and mortality within postoperative 30-day [1.84% (3/163) vs.0.01% (5/5397), χ(2)=33.642, P<0.001], longer ICU stay (median: 0 vs. 0, U=518 414, P<0.001), postoperative hospital stay (median: 17 days vs. 7 days, U=656 386, P<0.001), and total duration of hospitalization (median: 25 days vs. 12 days, U=648 129, P<0.001), and higher hospitalization costs (median: 71 000 yuan vs. 39 000 yuan, U=557 966, P<0.001). Conclusions: The incidence of SSI after abdominal surgery is 2.9%. In order to reduce the incidence of postoperative SSI, hypoproteinemia should be corrected before surgery, laparoscopic or robotic surgery should be selected when feasible, and the operating time should be minimized. More attentions should be paid and nursing should be strengthened for those patients with hypertension, small bowel surgery and seriously contaminated incision during the perioperative period.

Abstract
Objective: To investigate the clinicopathological characteristics and molecular genetics of atypical renal cysts. Methods: Six cases of atypical renal cysts were collected from Zhejiang Provincial People's Hospital, Hangzhou, China, between February 2014 and February 2019. The clinicopathological characteristics and disease progression were analyzed. The 3p deletion and trisomy of chromosomes 7 and 17 were detected using fluorescence in situ hybridization (FISH). Results: All of the 6 patients were male, aged 43-63 years (median: 52 years). Preoperative Bosniak classification showed 4 cases of grade Ⅱ, 1 case of grade Ⅰ and 1 of grade Ⅲ. Histologically, atypical renal cysts appeared as unilocular or multilocular cysts, lined by multilayered flattened or cuboidal-shaped clear or eosinophilic cells. They often showed short papillary projections, and lacked solid or nodular growth of the lesional cells within the wall or septa of the cysts. Histologically, these cysts could be classified into three categories: acquired cystic disease-associated renal cell carcinoma (ACKD-RCC)-like (3 cases), clear cell type (2 cases), and eosinophilic papillary type (1 case). Two cases of ACKD-RCC-like atypical renal cysts were accompanied by clear cell renal cell carcinomas. On immunohistochemical staining, ACKD-RCC-like atypical renal cysts were focally CK7+/AMACR+/CD57+, the clear-cell type atypical renal cysts were CK7+/CAⅨ+, and eosinophilic papillary type atypical renal cysts were CK7+/AMACR+. FISH analyses showed that one case of ACKD-RCC-like atypical renal cysts had trisomy 17 and one case of clear cell type had 3p deletion, while no signal abnormality was detected in the other cases. The six patients were followed up for 13 to 70 months (median: 27 months), and no evidence of renal cell carcinoma was noted. Conclusion: Atypical renal cysts are a group of lesions that are heterogeneous in clinical, histological and immunophenotypical and molecular genetic features. FISH analyses suggest that a subset of the cases may be precursors of currently known renal cell carcinomas. Extensively sampling and careful observation of the histological characteristics of the cyst wall are important for distinguishing atypical renal cysts from extensively cystic renal cell carcinomas.

Abstract
Objective: To investigate the clinicopathological characteristics, immunophenotypes, and diagnostic and differential diagnostic features of myxoid solitary fibrous tumor (SFT). Methods: Seven cases of myxoid SFT were collected from the archives of Zhejiang Provincial People's Hospital from January 2014 to December 2019. The clinical features, histomorphology, immunohistochemistry, molecular genetics and prognosis were analyzed and the relevant literature was reviewed. Results: There were three male and four female patients ranging from 32 to 67 years. Locations included the pleura (three cases), pelvic cavity, vagina, parotid gland, and nasal cavity(one each). Tumor size ranged from 2.7 to 13.5 cm. Histologically, all cases were characterized predominantly by the presence of myxoid stroma comprising 55% to 90% of the tumor (mean 72%). The tumors were composed of predominantly stellated, spindled or ovoid cells disposed haphazardly, in loose fascicles, or in anastomosing strands imparting a microcystic/reticular appearance in a extensively myxoid, richly vascularized stroma. Staghorn-shaped branching vessels and thin strands of collagen were commonly seen between tumors cells amidst the myxoid background. These myxoid areas were punctuated by small cellular areas showing diagnostic features of classical SFT, which were present in all seven cases. Areas showing giant cell angifibroma-like change were noted in 2 cases and focal lipomatous metaplasia was identified in 1 case. Atypical features suggestive of aggressive behavior were present in 2 cases and in one of the cases myxoid SFT with high-grade sarcomatous overgrowth was noted. Immunohistochemically, tumor cells in all cases stained positively for STAT6 and CD34. Polymerase chain reaction technique showed in both the examined cases the characteristic NAB2ex4-STAT6ex2 fusion gene. According to the Demicco's risk assessment model, four cases were classfied as low, one was classified as moderate and 2 was classified as high. Follow-up information was obtained in 4 cases. One tumor recurred 3 times within 48 months after operation, and the other 3 cases had no tumor recurrence and metastasis. Conclusions: Myxoid SFT represents a rare morphologic variant of SFT with biological behaviors ranging from indolent to aggressive. Myxoid SFT should be included in the differential diagnostic spectrums of soft tissue tumors with significantly myxoid change. Carefully searching for the typical SFT histomorphology with the use of immunohistochemistry and if necessary, molecularly testing for NAB2-STAT6 fusion can help to distinguish myxoid SFT from its many mimickers.

Abstract
Dao-di herbs are an important part of clinical medicine in traditional Chinese medicine. They are also precious wealth left to human beings from history, which contain deep traditional Chinese cultural connotations and play an important role in supporting and serving the Chinese medicine business. The relevant policy documents introduced by various national ministries and commissions have many contents and requirements related to the promotion of Dao-di herbs protection and industrial development. Due to the Dao-di herbs industry has a series of characteristics, such as a long chain, many involved links, long cycles, multiple production entities, multiple locations, and various types, the high-quality development of the industry has put forward higher requirements on the linkage between upstream and downstream, production entities, traceability of the whole process and information sharing. This article takes Dao-di herbs certification work as an application scenario and entry point, and discusses it from the perspective of block chain and information technology. It proposes the following work ideas: establish multi-party consensus from the macro-organizational management, business, and operational technical levels, and unblock channels for data and information, to achieve institutionalization of certification; establish certification-related standards and specifications to achieve certification standardization; build a certification hardware system to achieve certification networking; build a certification software system to develop functions for specific information content such as identity, origin, production, production process, quality, product and brand of authentic medicinal material production interactively, and realize certification programmatic; data security and sharing of related production activities to achieve socialization of certification. Make full use of modern technologies such as blockchain, the internet of things, big data and information technology, and through the joint participation of management, production, use and the public, the whole process information of Daodi herbs is integrated to form an interconnected information sharing application mode, thus, to serve and promote the high-quality development of Dao-di herbs industry.

Abstract
Beta-glucosidase (GBA), also known as acid β-glucosidase, exhibits an activity of glucosylceramidase (EC 3.2.1.45). Three main isoforms of β-glucosidases have been identified in mammals: GBA1, GBA2, and GBA3. The deficiency of these enzymes leads to glucosylceramide accumulation, resulting in Gaucher's disease. The present study is focused on the cytosolic β-glucosidase, GBA3, and its relationship with hepatocellular carcinoma (HCC). The expression of GBA3 mRNA in HCC was evaluated first using the TCGA database, and then by immunohistochemistry using tissue microarrays of 328 clinically characterized HCC samples and 151 non-tumor liver controls. Moreover, the presence of a correlation between GBA3 expression and clinicopathological characteristics of patients was examined. The obtained results indicated that the expression of GBA3 mRNA was significantly lower in HCC than in the adjacent non-tumor liver tissues. The expression of GBA3 was inversely related to the number of tumors (p=0.041), tumor size (p<0.001), Edmondson grade (p=0.007), microvascular invasion (p=0.049), patient status (p<0.001), and α-fetoprotein level (p<0.001). Patients exhibiting low GBA3 expression had a shorter survival time than those with high expression (p<0.001). In conclusion, the decreased GBA3 expression is strongly associated with a poor prognosis in HCC patients, and GBA3 may be a potential therapeutic target for HCC.

Abstract
Objective: To investigate the clinicopathological features,diagnosis and differential diagnosis of renal angiomyolipoma with epithelial cysts(AMLEC). Methods: Four cases of renal AMLEC diagnosed between January 2014 and June 2019 at the Department of Pathology,Zhejiang Provincial People's Hospital were subjected to clinicopathological, histological and immunohistochemistry analyses along with a literature review. Results: All the four patients were females and aged from 19 to 52 years (mean 34.5 years). Three cases were accidentally discovered by physical examination, and the medical history was 1 to 6 years. The preoperative imaging Bosniak classification was grade Ⅲ in 3 and grade Ⅳ in 1 case. The maximum diameter of the tumor ranged from 2.5 to 9.0 cm (average 5.0 cm). Histologically, all of the 4 tumors showed three histological components: (1) simple epithelial cysts lined by a layer of cuboidal/low-columnar to occasionally, hobnailcells; (2) a thin, compact subepithelial "cambium-like" layer of cellular, mullerian-like short spindle cell stromas with prominent admixedchronic inflammation; (3) a outermost layer of thick, long-fascicles of smooth muscle-like stromas, often surrounded by dysplastic, tortuous thick-walled blood vessels. There was often a prominent lymphatic channel network in the smooth muscle component forming slit like branched and curvilinear spaces. None of the 4 tumors had fat content.Immunohistochemically, the epithelial cells lining the cysts strongly expressed PAX8 and CK7. The subepithelial "cambium-like" stromas strongly expressed melanocytic markers (HMB45, Melan A, Cathspin K, MiTF) and mullerian markers (ER,PR,CD10), and were negative for smooth-muscle markers(SMA,desmin,calponin). The outermost layer of smooth muscle-like stromas strongly expressed smooth-muscle markers, and were only focally positive for melanocytic and mullerian markers. Follow-up information was obtained in 3 cases, among which no evidence of tumor recurrence or metastasis was found at 3, 5, and 66 months of follow-up, respectively. Conclusions: Renal AMLEC is a rare histological subtype of angiomyolipoma with benign biological behavior, and has characteristic histological and immunophenotypic characteristics.Pathologists should be familiar with the clinicopathological appearances of AMLEC and include it in the differential diagnostic spectrums of renal tumors with biphasic epithelial and mesenchymal features.

Abstract
Objective: To investigate the clinicopathologic features, diagnosis and differential diagnosis of large nested variant of urothelial carcinoma (LNUC) of urinary bladder. Methods: The clinical and pathologic data of five cases of LNUC of urinary bladder diagnosed between January 2014 and December 2018 at the Department of Pathology, Zhejiang Provincial People's Hospital were analyzed by immunohistochemistry (IHC) and Sanger sequencing. The relevant literature was reviewed. Results: All five patients were male with a mean age of 63 years (range, 48 to 81 years). The mean tumor size was 3.4 cm (range, 1.7 to 4.7 cm). Histologically, the invasive LNUC tumor cells formed medium to large sized nests of varying shapes, from regular round, bulbous, oval to irregularly fused, branched, dumbbell shaped glands, with mild stromal reaction. In all five cases, focal central necrosis and microcystic changes in the tumor nests were identified. Cytologically, the tumor cells were low grade in four cases; the remaining case was overall low grade with focal high grade areas. Mitoses were scarce. All cases possessed surface urothelial tumors, including three low-grade papillary carcinomas, one high-grade papillary carcinoma and one carcinoma in situ. Three of the LNUC were accompanied by small nested variant of urothelial carcinoma and two by conventional high grade invasive urothelial carcinoma. Perineural involvement and angiolymphatic invasion were each noted in four tumors. Radical cystectomy was performed in four cases with TNM stages as followings: pT3aN0M0 in two cases, pT4aN0M0 and pT4aN1M0 in one case each. The remaining case had transurethral bladder resection and was of pT2 stage. By IHC, all five cases were positive for CK7 and p40; four were positive for GATA3; two were positive for CK20; and the mean Ki-67 proliferation index was 18%. TERT promoter mutation status were successfully performed in three cases, with one showing mutation (C228T) and two were wild type. All patients received postoperative chemotherapy. At a follow-up of 2 to 11 months, one patient died of unrelated causes, two patients developed metastases, and two were alive with no evidence of disease. Conclusions: LNUC is a histologic subtype of urothelial carcinoma with deceptively benign features but aggressive behavior, and appreciation of its unique infiltration patterns can aid in diagnosis and differential diagnosis. LNUC tends to coexist with small nested variant of urothelial carcinoma, suggesting these may represent different manifestations of the same urothelial carcinoma subtype.

Abstract
Objective: To detect the clinicopathological features, immunophenotype, diagnosis, and differential diagnosis of composite pheochromocytoma(CP). Methods: Five cases of CP were collected at Zhejiang Provincial People's Hospital from January 2011 to January 2019. The clinical, radiological, histologic, immunohistochemical and outcome data were analyzed; the diagnosis and differential diagnosis were discussed. Results: The patients' age range was 52-68 years (mean 59 years, median 54 years), There were 4 males and 1 female, and the male to female ratio was 4∶1. Tumor size was 3-4 cm (mean 3.6 cm, median 3.5 cm). The most common clinical manifestation was adrenal mass. Histologically, the classical feature was two distinct morphologic components, one with tumor cells arranged in irregular nests, and with fine granular and basophilic oramphophilic cytoplasm; the other was composed of scattered ganglion cells in the background of Schwann cells organized in interwoven bundles. The components of pheochromocytoma expressed PHOX2B(5/5), synaptophysin (5/5), CgA (5/5), the sustentacular cells expressed S-100 protein; the components of ganglioneuroma expressed S-100 protein (5/5), NF (5/5), the ganglion cells were weakly positive for PHOX2B, synaptophysin and CgA. All the cases were surgically resected and all patients were free of recurrence at follow-up. Conclusions: CP is rare adrenal tumor, and it has typical histologic features but no specific clinical manifestations. Attention should be paid to its characteristic histomorphology with the use of PHOX2B, CgA, synaptophysin and S-100 protein immunohistochemistry that is helpful for its diagnosis.

Abstract
Bacterial infection remains one of the leading causes of death worldwide due to the continuous rise of multiple antibiotic-resistant bacteria. Focusing solely on bacteria as the drug targets is a major limitation inherent in the conventional antibiotic therapy. Recently, host-directed therapies have become such an innovative approach to modulate the host defense system and the interplay of innate and adaptive immunity. Our previous studies showed that memantine (MEM), an α7 nAChR antagonist, could efficiently block multi-drug resistant Escherichia coli-caused bacteremia and meningitis in a mouse model. However, the underlying mechanisms that govern the antibacterial effects of MEM are still unknown. In this study, we demonstrated that MEM is able to significantly suppress E. coli infection by enhancing E. coli-induced formation and release of NETs in vitro and in vivo. MEM could promote the trapping and bactericidal activities of the polymorphonuclear neutrophils (PMNs) in a manner dependent on α7 nAChR, since knockdown of this receptor noticeably reduces the survival ability of bacteria in PMNs while MEM no longer affects the survival of bacteria in PMNs. Our results also showed that when the expression of S100A9, an antiseptic protein, is inhibited, pathogen survival rates in PMNs increase significantly. MEM reverses this effect in a concentration-dependent manner. MEM stimulates the production of MPO, S100A9, and DNA in PMNs and accelerates the release of depolymerized chromatin fibers into the extracellular space, suggesting the formation of NETs. Taken together, our data suggest that MEM effectively blocks bacterial infection through the promotion of the antibacterial function of NETs induced by E. coli.

Abstract
Pennisetum sinese is a good forage grass with high biomass production and crude proteins. However, little is known about the endophytic fungi diversity of P. sinese, which might play an important role in the plant’s growth and biomass production. Here, we used high throughput sequencing of the Internal Transcribed Spacer (ITS) sequences based on primers ITS5-1737 and ITS2-2043R to investigate the endophytic fungi diversity of P. sinese roots at the maturity stage, as collected from four provinces (Shaanxi province, SX; Fujian province, FJ; the Xinjiang Uyghur autonomous prefecture, XJ and Inner Mongolia, including sand (NS) and saline-alkali land (NY), China). The ITS sequences were processed using QIIME and R software. A total of 374,875 effective tags were obtained, and 708 operational taxonomic units (OTUs) were yielded with 97% identity in the five samples. Ascomycota and Basidiomycota were the two dominant phyla in the five samples, and the genera Khuskia and Heydenia were the most abundant in the FJ and XJ samples, respectively, while the most abundant tags in the other three samples could not be annotated at the genus level. In addition, our study revealed that the FJ sample possessed the highest OTU numbers (242) and the NS sample had the lowest (86). Moreover, only 22 OTUs were present in all samples simultaneously. The beta diversity analysis suggested a division of two endophytic fungi groups: the FJ sample from the south of China and the other four samples from north or northwest China. Correlation analysis between the environmental factors and endophytic fungi at the class level revealed that Sordariomycetes and Pucciniomycetes had extremely significant positive correlations with the total carbon, annual average precipitation, and annual average temperature, while Leotiomycetes showed an extremely significant negative correlation with quick acting potassium. The results revealed significant differences in the root endophytic fungi diversity of P. sinese in different provinces and might be useful for growth promotion and biomass production in the future.

Abstract
Objective:The aim of this study is to assess the application value of maximum Young's modulus of shear wave elastography in combination with Thyroid Imaging Reporting and Data System set by the American College of Radiology in the diagnosis of benign and malignant thyroid nodules. Method:A retrospective analysis of 113 thyroid nodules with ultrasonographic imaging data was carried out. All nodules were subjected to SWE and conventional ultrasonography, and Emax was recorded and classified according to the 2017 ACR TI-RADS. With pathology as the gold standard, the ROC curve was drawn and the best diagnostic cut-off was selected for comparing their diagnostic performance. Result:Of the 113 thyroid nodules, 51 were benign and 62 were malignant. Best cut-off point for diagnosing malignant by SWE was Emax>40 kPa. And at that point, the sensitivity, specificity and accuracy of the average value of it were 74.2%, 76.5% and 75.2 %. Best cut-off point for diagnosing malignant by ACR TI-RADS was>TR4. The sensitivity, specificity and accuracy of the average value of it were 80.6%, 78.4% and 79.6%. The sensitivity of the combination of the two examinations was significantly higher than that of simple application of each of them, while there was no significant difference in the specificity and accuracy between them. Conclusion:The SWE and ACR TI-RADS classification systems have important clinical value in identifying the benign and malignant thyroid nodules. The combination of the two methods can improve the sensitivity, specificity and accuracy of the diagnosis.

Abstract
A novel synthetic route of producing ursodeoxycholic acid (UDCA) and obeticholic acid (OCA) was developed through multiple reactions from cheap and readily-available cholic acid. The reaction conditions of the key elimination reaction of mesylate ester group were also investigated and optimized, including solvent, base and reaction temperature. In the straightforward synthetic route for preparation of UDCA and OCA, most of the reaction steps have high conversions with average yields of 94% and 92%, and overall yield up to 65% (7 steps) and 36% (11 steps) from cholic acid, respectively. This promising route offers economical and efficient strategies for potential large-scale production of UDCA and OCA.

Abstract
OBJECTIVE To study the correlation of leukocyte subsets with sperm DNA damage in the semen of infertile men with asymptomatic genital tract infection (AGTI). METHODS This study included 111 infertile males with AGTI. After routine semen analysis, we determined the concentration of CD45+ leukocytes in the semen by immunocytochemistry, measured the concentrations of CD14+ cells of the mononuclear / macrophagic system and activated macrophages and HLA-DR+ cells in the semen by flow cytometry, and examined the sperm DNA fragmentation index (DFI) and the expression of 8-hydroxy-2'-deoxyguanosine (8-OHdG) by TUNEL assay. Then we analyzed the correlation of seminal leukocyte subsets with sperm DNA damage and routine semen parameters. RESULTS The concentration of CD45+ leukocytes was correlated significantly with those of CD14+ and HLA-DR+ cells in the semen (P <0.01), but not that of leukocyte subsets with routine semen parameters, sperm DFI, or the percentage of 8-OHdG-positive cells. The percentage of 8-OHdG-positive sperm was correlated positively with the sperm DFI (r = 0.48, P<0.01) but negatively with sperm concentration (r = -0.44, P <0.01). After adjusted for age, abstinence time and cigarette smoking, the percentage of 8-OHdG-positive sperm was correlated independently with sperm concentration (β = -0.25, P = 0.008) and DFI (β = 0.23, P = 0.05). CONCLUSIONS Sperm DNA damage is associated with poor semen quality but not with seminal leukocyte subsets in infertile males with asymptomatic genital tract infection.

Methods: Six cases of SCSG were collected from Zhejiang Provincial People's Hospital from January 2011 to March 2018. The clinical, histopathological and immunohistochemical features were analyzed and fluorescence in situ hybridization (FISH) was used to detect ETV6 gene rearrangement. Results: Four out of 6 tumors originated in the parotid gland and one of each in the minor salivary glands of soft palate and the buccal mucosa. Grossly, 4 cases were solid and 2 were partially cystic with maximum diameter ranging from 1.0 to 4.0 cm. Microscopically, 5 tumors showed typical features of low grade SCSG with tumor divided by thin fibrous septa into lobules composed of solid acinar, microcystic, follicular and papillary structures with abundant extracellular mucinous secretions. The tumor cells had cuolated or hobnail cytoplasm with low-grade nuclei and scarce mitoses. Perineural invasion was present in 1 case. The remaining tumor showed about 30% of the tumor areas with high-grade transformation characterized by proliferation of a distinct population of anaplastic cells arranged in irregular glandular, small nested and single cell patterns that were surrounded by desmoplastic stroma and invaded into surface mucosa with ulceration. Immunohistochemistry showed that all 6 tumors had diffuse and strong reactivities to S100 protein and cytokeratin 7, and 4 cases showed focal reactivity to gross cystic disease fluid protein 15 (GCDFP15), all were negative for discovered on gist 1 (DOG1), cytokeratin 20, p63 and calponin. High grade transformation cases were analysed, the high grade SCSG components showed a significantly increased Ki-67 index and cyclin D1 positive tumor cells compared to the conventional SCSG components. FISH analyses showed that 4 cases had ETV6 gene rearrangement. Eleven to seventy one months' follow-up showed no evidence of tumor recurrence nor metastasis. Conclusions: SCSG harbors characteristic genetic abnormalities with ETV6 gene rearrangement and typically shows a low grade morphology with occasionally, high grade transformation can be present.

Abstract
Objective: To investigate the clinicopathologic and differential diagnostic features of glomus tumor of the kidney. Methods: Four cases of glomus tumor of the kidney were collected from the archives of Peking University Third Hospital, the Second Hospital of Tianjin Medical University, Ningbo Yinzhou Second Hospital and Zhejiang Provincial People's Hospital between January 2012 to June 2017; the clinical and radiologic features, histomorphology, immunohistochemistry, ultrastucture and prognosis were analyzed and the relevant literature was reviewed. Results: Patients consisted of 2 men and 2 women with ages ranging from 37 years to 66 years (mean 55 years). Three patients had history of hypertensive disease (grade Ⅱ, 3 to 10 years). The tumors measured in maximum diameter from 3.0 cm to 4.0 cm (mean 3.6 cm) and showed gray-white to yellow and tan on cut surface. Macroscopical examinations showed all tumors were circumscribed but non-encapsulated. Histologically, 1 tumor presented as glomus tumor with extensive myxoid change, 1 as cellular and solid pattern glomus tumor, 1 as glomangioma with focal myopericytoma-like pattern and 1 as symplastic glomus tumor with areas resembling myopericytoma. The tumor cells in two cases showed scant cytoplasm and uniform, bland-appearing nuclei without mitoses. In one case, the tumor cells were epithelioid with abundant eosinophilic cytoplasm and relatively well-defined cell borders. There was an increased mitosis of 4/50 HPF; however, no evidence of atypical mitosis or nuclear atypia was noted. In the symplastic glomus tumor the tumor cells showed frequently nuclear pleomorphism without mitoses. By immunohistochemistry, all tumors showed strong and diffuse reactivities to at least 3 of the 4 muscle-associated markers (SMA, h-Caldesmon, MSA and Calponin), 3 tumors strongly and diffusely expressed collagen Ⅳ, 2 expressed CD34 and 1 focally expressed desmin; whereas markers including epithelial, neuroendocrine, nephrogenic, melanoma-associated, STAT6, S-100 protein, CD117 and β-catenin all were negative in all the 4 tumors. Ultrastuctural analysis was done in 2 cases and showed prominent cytoplasmic actin bundles and pericellular basement membrane, and lacking of rhomboid renin crystals in both tumors. The hypertension persisted after surgical resection for all the 3 patients with this medical history. Follow-up information (range: 6-64 months, mean: 44 months)showed that no evidence of local recurrence or distant metastasis was identified in all 4 patients. Conclusions: Glomus tumor rarely occurs in the kidney and usually has a good prognosis. Careful attention to its morphology with the judicious use of immunohistochemistry and ultrastuctural analysis can be helpful for its diagnosis and differential diagnosis.

Abstract
Objective: To investigate the histomorpholgic spectrum, immunophenotypic, and molecular genetic features of Sertoli cell tumor, not otherwise specified (SCT, NOS) of the testis. Methods: Seven cases of SCT, NOS of the testis were analyzed(4 from Peking University Third Hospital and 3 from Zhejiang Provincial People's Hospital) between 2008 and 2017. The histopathologic features were examined based on HE staining, and EnVision method was used for immunohistochemistry staining of calretinin, inhibin, β-catenin, cyclinD1, CD10, CKpan, neuroendocrine markers, WT1, Melan A, vimentin, SALL4, GATA3, PAX8, and S-100 protein. Mutational analysis of exon 3 of the CTNNB1 gene by polymerase chain reaction (PCR)-amplified sequences and direct sequencing was performed. Results: Patients ages ranged from 22 to 65 years (mean 43 years). The clinical manifestation in all was a slowly enlarging, painless testicular mass.The maximum diameter of the tumor ranged from 1.5 cm to 3.0 cm (mean 2.1 cm). Sectioning usually disclosed a tan-gray to white mass with vague lobular cut-surface. Microscopically, the tumors were well circumscribed and non-encapsulated; the tumor cells were rearranged in multiple growth patterns from diffuse solid sheets to trabeculae and cords, ribbon and solid or hollow tubules setting in variable amount of acellular fibrous stroma. Two cases showed acellular collagenous stroma constituted >50% of the tumor confirming to the diagnosis of sclerosing SCT. One case demonstrated a prominent myxoid stromal change. The tumor cells typically had moderate amounts of pale to lightly eosinophilic cytoplasm, 2 tumors had variable cells with abundant lipid-rich cytoplasm, and 1 other tumor showed scattered aggregates of multinucleated tumor cells. The tumor cells were bland-appearing without any evidence of atypia, mitoses were noted in 2 tumors (both were 1/50 HPF), but necrosis was absent. Immunohistochemical staining results as follows: vimentin (diffuse, 7/7), CD10 (diffuse membrane, 7/7); diffuse β-catenin nuclear and cytoplasm staining in 5 of 7 cases, and all the 5 cases showed diffuse cyclin D1 nuclear staining, β-catenin membrane staining in 2 of 7 cases, CKpan (5/7, focal or diffuse), calretinin (focal, 5/6), inhibin (focal, 3/7), synaptophysin (focal, 2/6), CD56 (focal or diffuse, 4/5), WT1 (diffuse nuclear, 4/5), and S-100 protein (diffuse, 3/7), and chromogranin A, Melan A, PAX8, GATA3 and SALL4 all were negative. Molecular genetic studies of PCR and direct sequencing showed CTNNB1 mutations in 4 of 7 (4/7) cases, 4 of the four mutation-carrying cases showed diffuse β-catenin nuclear and cytoplasm immunoreactivity and diffuse cyclin D1 nuclear immunoreactivity in the tumor cells. Conclusions: SCT, NOS of the testis typically shows significant heterogeneities in both morphology and immunohistochemistry, thus causing differential diagnostic confusions. Molecular analyses showed mutations of exon 3 of CTNNB1 in more than half of these tumors, and nuclear accumulation of β-catenin and over expression of cyclin D1 can be useful for the differential diagnosis of SCT, NOS.

Abstract
Objective: To investigate the clinicopathologic characteristics, immunophenotype, differential and diagnostic features of atypical spindle cell lipomatous tumor (ASLT). Methods: Three cases of ASLT were collected from January 2010 to March 2017 at Zhejiang Provincial People's Hospital. The clinical and imaging features, histomorphology, immunophenotype and prognosis were analyzed. Fluorescence in situ hybridization (FISH) was used to detect MDM2 gene amplification, and relevant literature was reviewed. Results: All three patients were adult males, aged 38, 43 and 54 years, respectively. One tumor originated in the subcutaneous soft tissue in the head and neck, one was located in the left primary bronchus and one in the latissimus dorsi muscle. Grossly, all three tumors were circumscribed and ranged from 4.0 to 5.8 cm in size. Microscopically, all showed a focally infiltrative front. These tumors were composed of variable proportions of spindle-shaped and adipocytic cells in a background of variable fibrous and edematous matrix. Scattered lipoblasts were easily seen. One tumor was composed predominately of spindle tumor cells, one of adipocytic cells, and one of equally mixed cell populations. The spindle tumor cells were generally bland-appearing with focal nuclear enlargement and hyperchromasia noted in one case. Mitosis was not seen in neither the spindle cells nor the adipocytic cells. By immunohistochemistry, diffuse and strong reactivity to CD34 of the spindle cells was noted in all cases, definite loss of Rb expression was noted in one of three cases, and S-100 protein was expressed only in the adipocytic cells. INI-1 was intact and Ki-67 index was 1% to 3%. All other markers including CDK4, MDM2, STAT6, SOX10, CD99, bcl-2, β-catenin, CD117, GFAP, CK, EMA, SMA and desmin were negative. FISH of MDM2 was done in two cases, and both showed no amplification. The ASLT in the head and neck had two recurrences during 17 months of follow-up, whereas the tumor in the latissimus dorsi was free of disease during 33 months of follow-up. Conclusions: ASLT is a rare subtype of low-grade adipocytic neoplasm and is distinctive from atypical lipomatous tumor/well-differentiated liposarcoma. The histomorpholgy of ASLT has significant heterogeneity and forms a continuous spectrum. ASLT needs to be distinguished from a series of benign and malignant soft tissue tumors.

Abstract
Objective: To investigate the clinicopathologic characteristics, immunophenotypes, molecular genetics, and diagnostic and differential diagnostic features of biphenotypic sinonasal sarcoma (BSNS). Methods: Three cases of BSNS were retrieved, the histomorphology, immunophenotype and molecular genetics were analyzed with review of literature. Results: There were 2 male and 1 female patient aged 45, 29 and 40 years, respectively.Computed tomography and magnetic resonance imaging examinations showed a large polypoid mass occupying the sinonasal cavity in all 3 patients. Microscopically, these tumors were un-circumscribed and composed of cellular spindle-shaped cells arranged in long and interlaced fascicles. A hemangiopericytoma-like growth pattern was frequently identified. The overlying hyperplastic respiratory epithelium invaginated down into the tumor forming a cystic (2 cases), glandular (1 case) structures and inverted in a papilloma-like (1 case)pattern, and foci of eosinophilic metaplasia were also noted in 2 of the three cases. The tumor nuclei were bland-appearing, mitoses were scarce and necrosis was absent. Immunohistochemically, the tumor cells showed co-expression of neural and myogenic markers in all the 3 cases, including that 3/3 showed diffuse and strong positivity of S-100 protein, 3/3 positivity of smooth muscle actin (1 diffuse and 2 focal), 1/2 diffuse positivity of calponin, 1/3 focal positivity of desmin, and 1/1 focal positivity of MyoD1.In addition, 1 detected for β-catenin showed focal nuclear positivity. None of the 3 showed positivity to cytokeratin, CD34 or SOX10 in the tumor cells.Ki-67 showed an index <5%, 10% and <2%, respectively. Fluorescence in situ hybridization analysis showed rearrangements of PAX3 gene in all 3 cases. In case 3, reverse transcription polymerase chain reaction, followed by Sanger sequencing, demonstrated an in-frame fusion between PAX3 and FOXO1.Follow-up information (range 3-15 months)showed no evidence of local recurrence or distant metastasis in three cases. Conclusions: BSNS is a newly described entity which can be readily confused with a variety of benign and malignant spindle cell tumors encountered in the sinonasal cavity; immunohistochemistry co-expression of neural and myogenic markers and PAX3 gene rearrangement can help distinguish this tumor from its many mimickers.

Abstract
Objective: To investigate the clinicopathologic characteristics, immunophenotypes, and differential diagnostic features of extra-pleural solitary fibrous tumor (SFT) with uncommon histology. Methods: Seven cases of extra-pleural SFT with uncommon histology were collected during January 2015 and December 2016 in Zhejiang Provincal People's Hospital; the clinical and radiologic features, histomorphology, immunophenotype and prognosis were analyzed. EnVision method was used for immunohistochemical staining of STAT6, CD34 and other differential diagnosis associated markers. Results: There were five male and two female patients, age from 23 to 54 years (mean=39 years). Three tumors were located in the soft tissue of head and neck, two in trunk subcutaneous soft tissue, one in sella region, and one in the kidney. Grossly the tumors ranged from 0.4 to 8.0 cm (mean=3.1 cm). Microscopically, all three head and neck cases resembled giant cell angiofibroma/giant cell subtype SFT, and one case showed sheet-like pattern of the multinucleated syncytial cells, creating a biphasic arrangement similar to myofibroma. Both truncal tumor resembled lipomatous type SFT, with one similar to dermatofibrosarcoma protuberans and the other to atypical spindle cell lipomatous tumor. The sella tumor showed morphology of a conventional SFT with high grade sarcomatous transformation. The renal tumor demonstrated a malignant SFT with entrapped benign renal tubules, mimicking a biphase synovial sarcoma or a malignant mixed epithelial and stromal tumor. By immunohistochemistry, all seven SFTs showed diffuse and strong nuclear reactivity to antibody against STAT6. Conclusions: Extra-pleural SFTs show a significant heterogeneity of morphology and biological behavior which could cause differential confusion.Careful attention to its characteristic histomorphology with the use of STAT6 immunohistochemistry can help distinguish this tumor from its many mimickers.
