Abstract
Objective: To compare the efficacy and safety of Tonghua Dongbao's insulin aspart injection (Rishulin) and NovoRapid (Novo Nordisk) in the treatment of diabetes. Methods: A 26-week, randomized, open-label, parallel-group, positive control drug and non-inferiority trial was conducted in 23 centers in China. A total of 563 diabetes with poor blood glucose control treated with insulin for at least 3 months before were included. The subjects were randomized(stratified block random method) into those receiving Rishulin or NovoRapid at a ratio of 3∶1. Both groups were combined with basal insulin (Lantus). The primary endpoint was the change in glycosylated hemoglobin (HbA1c) from baseline to the end of 24 weeks of treatment. Results: For full analysis set, after 24 weeks of treatment, HbA1c level of Ruishulin group decreased from (8.66±1.28)% to (7.77±1.09)% (P<0.001), and that of NovoRapid group decreased from (8.47±1.28) % to (7.65±0.97) % (P<0.001). Treatment difference in HbA1c (NovoRapid group-Ruishulin group) was -0.061% (95%CI -0.320-0.199). HbA1c<7.0% target reacing rates were 24.26% and 21.21% (P=0.456), and HbA1c<6.5% target reacing rates were 9.65% and 6.82% (P=0.310) in Ruishulin group and NovoRapid group, repectively. The standard 2 hours postprandial blood glucose (2hPG) in Ruishulin group decreased from (16.23±5.22) mmol/L to (12.65±4.57) mmol/L (P<0.001), and 2hPG in NovoRapid group decreased from (16.13±5.37) mmol/L to (11.91)±4.21) mmol/L (P<0.001). The fingertips blood glucose at 7-point of both groups exhibited varying degrees of reduction compared with those at baseline, repectively. Positive ratios of specific antibodies were 31.68% in Ruishulin group and 36.36% in NovoRapid group (P=0.320). Ratios of negative to positive were 7.43% and 10.61% (P=0.360), and ratios of positive to negative were 10.40% and 7.58% (P=0.360) in Ruishulin group and NovoRapid group, respectively. The incidence of hypoglycemia was 60.05% and 55.40% (P=0.371), and the incidence of adverse events was 76.60% and 77.70% (P=0.818) in Ruishulin group and NovoRapid group, respectively. Conclusions: Rishulin is not inferior to NovoRapid, and has shown good efficacy and safety. It can be an ideal choice for clinicians in patients with poor blood glucose control with insulin.

Abstract
The structure and performance of nuclear cytoplasmic autophagosomes was explored. Seventeen cases of hepatocellular carcinoma and liver cells with other diseases from liver tissues were selected. The nuclear cytoplasm were isolated and degraded by the nuclear membrane. Damaged cytoplasm had damaged its own membrane and the surrounding nuclear tissues other than the nuclear membrane, leading to specific nucleolysis and cell death of liver cancer cells and liver cells.

Abstract
Background Esophageal neuroendocrine carcinomas (NECs) are exceedingly rare and poorly understood. The aims of the retrospective study were to delineate the clinicopathologic features and prognosis of patients with the disease. Methods We performed a retrospective study containing 53 patients of esophageal NECs in our center from 2002 through 2018. Patients were assigned to the pure esophageal NECs group and the esophageal NECs mixed with squamous carcinoma and/or esophageal adenocarcinoma (MiNECs) group. Demographic, clinical, pathologic and prognostic factors were recorded and analyzed. Results Of the 53 patients, elderly male patients were predominant. Dysphagia was the most common symptom (45/53, 84.9%). Most tumors were centered in the middle esophagus (36/53,67.9%).Ulcerated appearance was frequently seen in the pure NECs (56.8%), and the tumors in the MiNECs group mostly represented elevated types (57.9%). Synaptophysin (38/45, 84.4%), chromogranin A (21/38, 55.3%) and CD56(23/27, 85.2%) have been proven to be positive markers for NECs. Most patients (46/53, 86.8%) received surgery combined with chemotherapy. Though the pathologic stages were alike (P = 0.129), the median survival time was 3.53 years for the pure NECs group and 7 years for the MiNECs group. In multivariate analysis, pathologic stage (RR = 1.938, P = 0.045) and age (RR = 2.410, P = 0.028) were independent prognostic factors for patients with MiNECs. The prognosis of patients with pure NECs was independent from any factors. Conclusions Careful endoscopic examination could help distinguish pure NECs from MiNECs. NECs were aggressive, but a relative better prognosis for patients with MiNECs. Surgery should be performed if applicable, and chemotherapy might be helpful.

Abstract
OBJECTIVE To investigate the clinical and histopathologic features of testicular seminoma with syncytoplasmic trophoblastic components. METHODS Using light microscopic staining, we analyzed the clinical and histopathologic characteristics, diagnosis, differential diagnosis and prognosis of 3 cases of testicular seminoma with syncytoplasmic trophoblastic components, and reviewed the relevant literature. RESULTS All the 3 cases were typical seminoma with syncytiotrophoblastic giant cells. Immunohistochemistry showed strong expressions of CD117 OCT-4, SALL4 and PLAP in diffuse tumor cells, and that of hCG in syncytiotrophoblastic cells. Continuous monitoring and consultation exhibited normal levels of serum β-hCG in all the cases after postoperative chemotherapy. CONCLUSIONS Testicular seminoma with syncytiotrophoblastic giant cells and increased serum β-hCG is a rare subtype, which occurs mostly in young people, sensitive to chemotherapy postoperatively and with a relatively good prognosis.

Abstract
Eph/ephrin signaling plays important roles both in embryonic development and human disease. The Eph receptors are involved in tumor development, progression, metastasis, and prognosis. The tumor microenvironment plays a critical role in tumor initiation, progression, metastasis, and resistance to therapy. Increasing data show that Ephs and ephrins mediate cell-cell interactions both in tumor cells and in tumor microenvironment. This review focuses on recent advances in dissecting the role of Eph and ephrin in tumor cells, tumor angiogenesis, epithelial-mesenchymal transition, hypoxia, and inflammation.

Abstract
Adiposis is reputed as a twin disease of type 2 diabetes and greatly harmful to human health. In order to understand the molecular mechanisms of adiposis, the changes of physiological, pathological, epigenetic and correlative gene expression were investigated during the adiposis development of C57BL/6J mice induced by long time (9 months) high-fat and high-sucrose diet (HFSD) sustainably. The results showed that mRNA transcription level of the Leptin, Glut4 and Glut2 genes have been obviously changed, which exhibit a negative correlation with methylation on their promoter DNA. The results also revealed that HFSD induced higher level of DNA methyltransferase 1 (DNMT1) in fat tissue might play important role in regulating the changes of methylation pattern on Glut4 and Leptin genes, and which might be one of the molecular mechanisms for the adiposis development.

Abstract
Objective: To explore short-term effect of intense pulsed light (IPL) combined with meibomian gland expression in treating meibomian gland dysfunction (MGD). Methods: This study was a prospective, randomized, double-masked, controlled study. Forty-four MGD patients were enrolled in the study and received three consecutive IPL treatments with an interval of 4 weeks. One eye of each patient was randomly assigned as the study eye receiving the IPL therapy with an energy of 14-16 J/cm(2), and the fellow eye was as the control eye receiving a placebo therapy with 0 J/cm(2). Meibomian gland expression was immediately performed after the IPL treatment in both eyes. Efficacy was evaluated through assessment of the meibomian gland yielding secretion score (MGYSS) , SPEED questionnaire, tear film break-up time (TBUT), cornea fluorescein staining and infrared meibography. Safety was evaluated through best spectacle corrected visual acuity, intraocular pressure, slit lamp examination and fundus examination. These examinations were performed before and after each treatment. Results: Significant improvements were observed in the MGYSS and TBUT after IPL treatments (P<0.05). The improvements compared to the baseline of MGYSS at the upper eyelid in the treatment eyes were significantly higher than those in the control eyes after the first treatment (Z=-2.036, P=0.003). The improvements compared to baseline of MGYSS at the lower eyelid and the TBUT in the treatment eyes were significantly higher than those in the control eyes after the second treatment (Z=-2.999 and -2.036, respectively P=0.007 and 0.042, respectively). SPEED and cornea fluorescein staining were decreased in both eyes after IPL treatments, but there was no statistical difference between the two eyes. No obvious complication was observed in the study. Conclusions: IPL treatment combined with meibomian gland expression is an efficient and safe therapy, and can increase meibomian gland yielding secretion, increase the TBUT, relieve the symptoms and repair the corneal epithelium defects for MGD eyes.

Abstract
Circulating tumor cells (CTCs), isolated as a 'liquid biopsy', may provide important diagnostic and prognostic information. Therefore, rapid, reliable and unbiased detection of CTCs are required for routine clinical analyses. It was demonstrated that negative enrichment, an epithelial marker-independent technique for isolating CTCs, exhibits a better efficiency in the detection of CTCs compared with positive enrichment techniques that only use specific anti-epithelial cell adhesion molecules. However, negative enrichment techniques incur significant cell loss during the isolation procedure, and as it is a method that uses only one type of antibody, it is inherently biased. The detection procedure and identification of cell types also relies on skilled and experienced technicians. In the present study, the detection sensitivity of using negative enrichment and a previously described unbiased detection method was compared. The results revealed that unbiased detection methods may efficiently detect >90% of cancer cells in blood samples containing CTCs. By contrast, only 40-60% of CTCs were detected by negative enrichment. Additionally, CTCs were identified in >65% of patients with stage I/II lung cancer. This simple yet efficient approach may achieve a high level of sensitivity. It demonstrates a potential for the large-scale clinical implementation of CTC-based diagnostic and prognostic strategies.

Abstract
OBJECTIVE To investigate the pathological characteristics, diagnosis, and differential diagnosis of embryonal rhabdomyosarcoma (ERMS) in the male reproductive system. METHODS We obtained the clinicopathological features, immunophenotypes, and electron microscopic findings of 11 male patients with ERMS in the reproductive system from 2000 to 2015, analyzed the data, and reviewed relevant literature. RESULTS ERMS developed in these patients at a median age of 17 (9-58) years, 3 cases in the testis, 4 in the scrotum, 1 in the epididymis, and 3 in the prostate. ERMS presented no clinical specificity, which made it difficult to be differentiated from inflammatory and other benign lesions. Microscopically, the tumor cells were arranged in a diffuse or fascicular distribution and mainly composed of short spindle-like, round, or irregularly shaped cells with nuclear hyperchromatism, the cytoplasm strongly eosinophilic, with differentiation of the striated muscle. Some of the cells were naively differentiated or tennis racket-shaped and some exhibited vacuolar degeneration in the cytoplasm. The nuclei were round or short spindle-shaped with visible nucleoli and mitoses. Immunohistochemically, the tumor cells were positive for Myogenin (5/6), Desmin (11/11), MyoD1 (8/9), and Myosin (1/2). Electron microscopy revealed early myofibrils in the cytoplasm of the tumor cells. CONCLUSIONS ERMS is a rare and highly malignant tumor characterized by local invasion and early metastasis and apt to develop in the reproductive system of young males. The diagnosis of the malignancy is mainly based on its histopathological and immunohistochemical manifestations, combined with electron microscopy when necessary. Early surgical resection in combination with radio- and chemotherapy is recommended for its treatment, which could reduce the recurrence of the tumor and improve the survival of the patients.

Abstract
Ovarian small-cell carcinoma hypercalcemic type (OSCCHT) is a relatively rare and highly fatal gynecological malignancy. Prognosis is generally poor, and no treatment guidelines are offered. Here, we report a case of OSCCHT successfully treated by complete excision and a postoperative chemotherapy scheme of carboplatin and paclitaxel. A 29-year-old female with with pelvic mass and significantly increased serum calcium (4.90 mmol/L) was referred to our hospital on August 22, 2013. Abdominal ultrasonography and computed tomography revealed a pelvic nonhomogeneous echo of a 113×102 mm mass, possibly coming from the adnexa of the uterus. Preoperative examinations indicated high levels of serum calcium and relevant acute renal dysfunction; hence, continuous renal replacement therapy was performed until all tests reached minimum operation requirements. Interestingly, after excision, serum calcium levels decreased rapidly and therefore, extra calcium had to be taken in order to take the level back up to normal. The patient was diagnosed with OSCCHT based on the clinical data and pathological examinations. After six cycles of chemotherapy, the patient was in a good condition and on follow-up there were no signs of recurrence.

Abstract
Recent studies have revealed that the receptor activator of nuclear factor-kappa B ligand/RANK/osteoprotegerin (RANKL/RANK/OPG) system has an important role in vascular calcification, which is contributory to various cardiovascular diseases and intimately linked to the regulation of blood pressure. Therefore, we performed a case-control study to investigate the associations of 21 single-nucleotide polymorphisms (SNPs) in the TNFSF11, TNFRSF11A and TNFRSF11B genes in the RANKL/RANK/OPG system with hypertension and blood pressure in post-menopausal Chinese women. In this study, 503 hypertensive patients and 509 normal controls were recruited. Genotyping was performed using the high-throughput Sequenom genotyping platform. The results showed that two SNPs (rs6567270 and rs4603673) in the TNFRSF11A were associated with hypertension (P=0.010 and P=0.013, respectively) and systolic blood pressure (P=0.024 and P=0.023, respectively). One SNP (rs9646629) in the TNFRSF11A showed significant association with diastolic blood pressure (P=0.031). The results of this study suggest that TNFRSF11A but not TNFSF11 and TNFRSF11B genetic variation is associated with hypertension and blood pressure in Chinese women. The findings provide additional support for the genetic role of RANKL/RANK/OPG system in hypertension and blood pressure regulation.

Abstract
OBJECTIVE To study the clinicopathological characteristics of papillary cystadenoma of the epididymis. METHODS Using routine pathology and immunohistochemistry, we observed the surgically obtained samples from 2 cases of papillary cystadenoma of the epididymis, analyzed their pathological features and clinical presentations, and reviewed the related literature. RESULTS The 2 patients were both adult males. The tumors typically manifested as painless swelling in the epididymis, with occasionally dull pain and tenesmus in 1 of the cases. Pathologically, the lesions exhibited three morphological features, i. e., dilated ducts and small cysts surrounded by fibrous connective tissue, adenoid papillary hyperplasia into the cysts embraced by fibrovascular stroma, and acidophil substance present in the cysts. Immunohistochemistry showed that the tumors were strongly positive for CK8/18, CK7, and EMA, but negative for CK20, CEA, MC, Calretenin, P53, P63, SMA, VHL, and CD10, with the positive rate of Ki-67 <1%. Follow-up visits revealed good prognosis in both cases. CONCLUSION Papillary cystadenoma of the epididymis is a rare benign tumor in the male urogenital system, which may be accompanied by the VHL syndrome. Surgery is the first choice for its treatment.

Abstract
UNLABELLED Association between 22 single nucleotide polymorphisms (SNPs) in the TNFSF11, TNFRSF11A, and TNFRSF11B genes in the RANKL/RANK/OPG pathway with bone mineral density (BMD) in 881 post-menopausal women. Our results suggest that TNFSF11 and TNFRSF11A, but not TNFRSF11B, genetic polymorphisms influence BMD mainly in the femoral neck in post-menopausal Chinese women. INTRODUCTION The aim of this study was to assess the relationship of polymorphisms in the TNFSF11, TNFRSF11A, and TNFRSF11B genes in the RANKL/RANK/OPG pathway with bone mineral density (BMD) in a cohort of Chinese post-menopausal women. METHODS A cross-sectional study was conducted in 881 post-menopausal women aged 50-89 years. All participants underwent lumbar spinal (LS) and femoral neck (FN) BMD evaluation by dual-energy X-ray absorptiometry. Twenty-two TNFSF11, TNFRSF11A, and TNFRSF11B SNPs were genotyped. We tested whether a single SNP or a haplotype was associated with BMD variations. RESULTS Two SNPs in the TNFSF11 gene (rs2277439 and rs2324851) and one in the TNFRSF11A gene (rs7239261) were found to be significantly associated with FN BMD (p = 0.014, 0.013, and 0.047, respectively). Haplotype TGACGT of TNFSF11 rs9525641-rs2277439-rs2324851-rs2875459-rs2200287-rs9533166 was a genetic risk factor toward a lower FN BMD (beta = -0.1473; p = 0.01126). In contrary, haplotype TAGCGT of TNFSF11 rs9525641-rs2277439-rs2324851-rs2875459-rs2200287-rs9533166 was genetic protective factor for LS BMD (beta = 0.3923; p = 0.04917). CONCLUSIONS Our findings suggest that TNFSF11 and TNFRSF11A, but not TNFRSF11B, genetic polymorphisms influence BMD mainly in the femoral neck in post-menopausal Chinese women. This contributes to the understanding of the role of genetic variation in this pathway in determining bone health.

Abstract
BACKGROUND Basal cell carcinoma (BCC) is a prevalent form of nonmelanoma skin cancer. Although numerous studies in white populations suggest that mutations in the TP53 gene play an important role in the development of BCC, it is not clear whether this is also the case in East Asian populations such as in China. AIM To investigate the frequency and the features of TP53 mutation in sporadic BCC in a Chinese population. METHODS In total, 30 patients with sporadic BCC, who had previously taken part in a study on PTCH1 mutations, were enrolled. BCC and control cells were obtained by laser-capture microdissection, and DNA was amplified and sequenced for analysis of TP53 mutations. RESULTS In the 30 BCC samples, 6 TP53 point mutations were found (frequency of 20%), and 4 of these 6 mutations had ultraviolet (UV)-specific alterations. Combining these results with those of the previous study on PTCH1 mutations, we found that two patients with had three types of genetic alterations (each had two PTCH1 mutations and one TP53 point mutation). A further two patients each had one PTCH1 mutation and one UV signature TP53 mutation. In addition, the total number of UV-specific mutations of PTCH1 and TP53 accounted for 20% of the total patient group. CONCLUSIONS The incidence of TP53 mutation in BCC in our Chinese subjects was lower than that reported for white populations. Many of the patients carried mutations of other genes in addition to of TP53. The majority of TP53 mutations were UV-induced specific alterations. However, the results of the two studies on TP53 and PTCH1 indicated that the incidence of UV-specific mutations is much lower in Chinese than in white populations.

Abstract
In this study, we reported the first PEComa arising within the cervix with TFE3 gene rearrangement and aggressive biological behavior. Morphologically, the tumor showed infiltrative growth into the surrounding parenchyma. The majority of tumor cells were arrayed in sheets, alveolar structures, or nests separated by delicate fibrovascular septa. There was marked intratumoral hemorrhage, necrosis, and stromal calcifications. The tumor cells had abundant clear cytoplasm, focally containing finely granular dark brown pigment, morphologically considered to be melanin. Immunohistochemically, the tumor cells demonstrated moderately (2+) or strongly (3+) positive staining for TFE3, HMB45, and Melan A but negative for CKpan, SMA, S100, PAX8, and PAX2. The presence of Ki-67 protein demonstrated a moderate proliferation rate, with a few Ki-67-positive nuclei. Using a recently developed TFE3 split FISH assay, the presence of TFE3 rearrangement was demonstrated. All these clinicopathologic features are suggestive of TFE3-rearranged PEComas of the cervix. Our results both expand the known characteristics of primary cervix PEComas and add to the data regarding TFE3 rearrangement-associated PEComas.

Abstract
In this study, we analyzed the immunohistochemical and molecular profiles of an unusual RCC showed coexistent absence of INI1 and BRG1 expression, rhabdoid morphology, and poor prognosis. Histologically, the tumor had rhabdoid features, which were demonstrated by large round to polygonal cells with eccentric nuclei, prominent nucleoli, and eosinophilic cytoplasm varying from abundant to scanty. Immunohistochemically, the tumor were positive for BRM, PBRM1, ARID1A, CD10, CKpan, Vimentin, carbonic anhydrase IX (CA-IX), and P504S (AMACR) but negative for INI1, BRG1, HMB45, melan A, CK7, CD117, Ksp-cadherin, TFEB, TFE3, and Cathepsin K. We detected all three exons status of the VHL gene of the tumor and observed 1 somatic mutations in 1st exon. Chromosome 3p deletion, coupled with polysomy of chromosome 3 was also found. Based on these findings, it is further indicated that in some cases, rhabdoid RCC may arise from clear cell RCC. SWI/SNF chromatin remodeling complex may be an attractive candidate for being the "second hit" in RCCs and may play an important role during tumor progression. The role of SWI/SNF complex in rhabdoid RCC should be further studied on a larger number of cases.

Abstract
Recent studies have demonstrated that cathepsin K seems to be a powerful marker in identifying the microphthalmia associated transcription factor (MITF) family tumors such as renal perivascular epithelioid cell neoplasms (PEComas), alveolar soft part sarcoma, and translocation-associated renal cell carcinomas. However, the expression of cathepsin K in melanocytic lesions has not been well characterized. Our aim was to investigate the expression of cathepsin K in a wide histological spectrum of melanocytic lesions and to evaluate its potential diagnostic and molecular target therapy usefulness in comparison with other commonly used markers. 143 consecutive melanocytic lesions were selected for study including 56 primary malignant melanomas, 62 metastatic melanomas, and 25 benign nevi (16 intradermal melanocytic nevi and 9 compound melanocytic nevi). 107 of the 118 (91%) primary and metastatic melanomas displayed a high percentage of cells with moderately to strongly positive reactions for cathepsin K (mean 82%; range 0-95%). MITF, HMB45, Melan-A, and S100 were expressed in 85, 76, 78 and 96% of cases, respectively, with various percentages of positive cells (mean, 63, 49, 55 and 86%; range 0-90, 0-80, 0-90 and 0-95%). Among the benign nevi, cathepsin K, MITF, HMB45, Melan-A, and S100 were expressed in 88, 80, 36, 68 and 100% of cases, respectively. Cathepsin K appears to be consistently and strongly expressed in melanocytic lesions and valuable in distinguishing malignant melanomas from the majority of human cancers.

Abstract
Clear cell papillary renal cell carcinoma (CCPRCC) is a recently recognized renal neoplasm, which was initially described in end-stage renal disease (ESRD), but some cases have been reported in otherwise normal kidneys. We report a series of 11 CCPRCC (age range, 33-72 years; male-to-female ratio, 8:3). Follow-up was available for 8 patients. No patients developed local recurrence, distant or lymph-node metastasis, or cancer death. Histologically, all tumors exhibit morphologic features typical of CCPRCC including a mixture of cystic and papillary components, covered by small to medium-sized cuboidal cells with abundant clear cytoplasm. All 11 cases exhibited moderate to strong positivity for CK7, CA9, Vim, and HIF-1α, coupled with negative reactions for CD10, P504S, and RCC. We did not find any VHL gene mutations in all 11 cases. Losses of chromosomes 3 (monoploid chromosome 3) was detected in 3 cases. Ultrastructurally, the tumor cells composed of numerous glycogens with scanty cell organelles, reminiscent of clear cell renal cell carcinoma (CCRCC). In conclusion, the coexpression of CA9 and HIF-1α in the absence of VHL gene abnormalities in CCPRCC suggests activation of the HIF pathway by mechanisms independent of VHL gene mutation. Losses of chromosomes 3 (monosomies chromosome 3) was detected in 3 cases suggesting that at least some of these lesions have demonstrated abnormalities of chromosomes 3. Ultrastructurally, CCPRCC composed of numerous glycogens with scanty cell organelles, reminiscent of CCRCC suggesting the close pathogenesis relationship of CCPRCC with CCRCC.

Abstract
OBJECTIVE To study the clinicopathologic features, immunophenotype and genetic changes of perivascular epithelioid cell neoplasms (PEComa). METHODS A total of 25 cases of PEComa located in various anatomic sites were selected for immunohistochemical staining (SP or EnVision method). TFE3 fluorescence in-situ hybridization was also performed to determine the TFE3 gene status. RESULTS The age of patient ranged from 21 to 61 years (mean = 43 years). The male-to-female ratio was 1: 1.3. Histologically, 22 cases represented conventional angiomyolipomas, composed of a mixture of adipose tissue, spindle element, epithelioid smooth muscle cells and abnormal thick-walled blood vessels in various proportions. Three cases involving lung, soft tissue and broad ligament had subtle but distinctive morphologic features. Nested or sheet-like architecture with epithelioid or spindle cells was observed. Immunohistochemical study showed that HMB 45, melan A, smooth muscle actin and cathepsin K were expressed in 80% (20/25), 88% (22/25), 88% (22/25) and 100% (25/25) of PEComa, respectively. Within positive cases, the average proportion of positive tumor cells was 36%, 41%, 35% and 90% respectively for HMB 45, melan A, smooth muscle actin and cathepsin K. TFE3 was negative in all of the 22 renal and hepatic PEComa studied, while it was positive in the 3 cases of extra-hepatorenal PEComa. None of the 25 cases exhibited evidence of TFE3 gene fusion or amplification. CONCLUSIONS Extra-hepatorenal PEComa have distinctive morphologic features and are associated with TFE3 overexpression. Cathepsin K immunostaining demonstrates high sensitivity and specificity in PEComa, better than other commonly employed immunomarkers. This marker is thus useful in diagnosis of PEComa and distinction with other neoplasms.

Abstract
In this study, we presented an additional case of renal hemangioblastoma, which demonstrates PAX2 and focal CD10 expression. Histologically, the tumor consisted of sheets of oval or polygonal cells and a prominent vascular network. The tumor cells varied in size, and possessed pale or eosinophilic cytoplasm that sometimes contained sharply delineated fine vacuoles. The tumor cell nuclei with inconspicuous nucleoli showed moderate nuclear atypia and pleomorphism. Focal areas of stromal hyalinization and sclerosis were detected. On account of its strong or moderate immunoreactivity for the a-inhibin, S100, NSE, and EGFR, the diagnosis of renal hemangioblastoma was established. For further evidence of VHL deficiency, the tumor was subjected to VHL sequence analysis of all three exons and fluorescence in situ hybridization (FISH) detection for chromosome 3p deletion. None of the VHL gene mutations and chromosome 3p deletion was detected in the tumor. Because of several shared morphological and immunophenotypic features, renal hemangioblastoma may be underrecognized and should be included in the differential diagnosis of primary renal tumors, in particular clear cell renal cell carcinoma. The unexpected positive staining of PAX2 and CD10 in renal hemangioblastoma should be particular concerned. Using a combination of immunoprofile may be helpful to the differential diagnosis of these renal tumors.

Abstract
In this study, we reported an additional genetically confirmed case of renal cell carcinomas (RCCs) with t(6;11)(p21;q12) showing an unusual histological pattern. Histologically, the tumor was entirely composed of small to intermediate sized tubules and cysts. The tubules and cysts were lined by a single layer of flat, hobnail, cuboidal to columnar epithelial cells. Most cells demonstrated abundant eosinophilic cytoplasm with regular, round or oval nuclei and some inconspicuous nucleoli. All these morphological features are suggestive of tubulocystic carcinoma of the kidney. However, the tumor demonstrated moderately (2+) or strongly (3+) positive staining for TFEB, Cathepsin K, Ksp-cadherin, and vimentin but negative for TFE3, CD10, HMB45, melan A, CKpan, and CK7. Using a recently developed TFEB split FISH assay, the presence of TFEB rearrangement was demonstrated. Our results support the clinical application of a TFEB break-apart FISH assay for diagnosis and confirmation of TFEB RCC and further expand the morphologic spectrum that may be present in these neoplasms, sometimes raising a challenging differential diagnosis with other renal tumors.

Abstract
AIMS Recent studies have demonstrated that cathepsin K seems to be a powerful marker in identifying renal perivascular epithelioid cell neoplasms (PEComas). However, the expression in extrarenal PEComas has not been well characterized due to their rare incidence. Our aim was to investigate the expression of cathepsin K in a wide spectrum of extrarenal PEComas and evaluate its potential diagnostic usefulness in comparison with other commonly used markers. METHODS AND RESULTS Twenty-three cases of PEComa (liver, n = 9; lung, n = 1; broad ligament of uterus, n = 1; vertex subcutaneous soft tissue, n = 1; abdominal wall, n = 1; and kidney, n = 10) were selected for study. All displayed a high percentage of cells with moderately to strongly positive reactions for cathepsin K (mean 91%; range 80-100%). HMB45, Melan-A and smooth muscle actin (SMA) were expressed in 78, 87 and 87% of cases, respectively, with various percentages of positive cells (mean, 34, 40 and 38%; range 0-80, 0-90 and 0-90%). Transcription factor E3 (TFE3) was expressed strongly in only three cases; none exhibited evidence of TFE3 gene fusion or amplification. CONCLUSIONS Cathepsin K appears to be more powerful than other commonly used markers in diagnosing a wide spectrum of PEComas and distinguishing them from the majority of human cancers.

Abstract
Drug-drug interactions (DDIs) may adversely affect the prevention and cure of diseases. The effects of three polyether ionophore antibiotics, salinomycin (SAL), monensin (MON), and maduramycin (MAD) on the pharmacokinetics of florfenicol (FFC) were investigated in broilers. The chickens were fed rations with or without SAL (60 mg/kg feeds), MON (120 mg/kg feeds), or MAD (5 mg/kg feeds) for 14 consecutive days. FFC was given to the chickens either intravenously (i.v.) or orally (p.o.) at a single dose of 30 mg/kg body weight. Blood samples were taken from each chicken at 0-24 h postadministration of FFC. The plasma concentration of FFC was detected by high-performance liquid chromatography. The plasma concentration of FFC decreased with i.v. or p.o. co-administration of SAL, MON, or MAD in broilers, implying occurrence of DDIs during the co-administration of FFC with these ionophores. Our findings suggest that more attention should be given to the use of FFC to treat bacterial infections in chickens supplemented with polyether ionophore antibiotics.

Abstract
OBJECTIVE The aims of this study were to evaluate the clinical utility of a fluorescence in situ hybridization (FISH) assay as a non-invasive molecular test to distinguish urothelial carcinoma (UC) in the upper urinary tract (UUT) from benign lesions presenting with hematuria. STUDY DESIGN The chromosomal abnormalities of chromosomes 3, 7, 17 and 9 (p16) in hematuria specimens from 34 patients with UUT-UC and 33 patients with benign disorders were detected using a set of fluorescently labeled DNA probes. The abnormalities of the chromosomes were determined and analyzed between UUT-UC and benign disorders. RESULTS Chromosomal abnormalities were detected in 25 of 34 (73.5%) patients with UUT-UC and in 2 of 33 (6.1%) patients with benign disorders (p < 0.001). CONCLUSIONS FISH of chromosomes 3, 7, 9 and 17 performed on exfoliated cells from voided urine specimens may serve as a non-invasive tool to distinguish UUT-UC from benign disorders presenting with hematuria.

Abstract
BACKGROUND Alterations of the PTCH1 gene have been found to contribute to both familial and sporadic basal cell carcinoma (BCC), especially in Caucasian patients. Furthermore, the majority of PTCH1 gene mutations in sporadic BCCs in Caucasian patients carry ultraviolet (UV) signatures, suggesting the key role of UV light in BCC development. However, sporadic BCC in non-Caucasian population has a lower incidence, and the pathogenesis remains largely unknown. To date, there has been no mutation analysis on PTCH1 gene in Chinese patients with sporadic BCCs. OBJECTIVE To investigate genetic alterations of the PTCH1 gene in Chinese sporadic BCCs. METHODS Direct sequencing was used to screen for mutations in PTCH1 in 31 microdissected samples in Chinese sporadic BCCs. In addition, single nucleotide polymorphisms (SNPs) were studied for loss of heterozygosity (LOH). RESULTS Nineteen PTCH1 mutations in 17 of the 31 BCCs (54.8%) were identified. SNP analysis revealed LOH of PTCH1 in 10 of 23 BCCs (43.5%). Interestingly, the majority of mutations identified (63.2%) were insertion/deletion, which was different from the results in Caucasian cases whose mutations are predominantly point mutations. Only two (10.5%) of the remaining seven mutations were UV-specific C → T transition or tandem CC → TT transitions. All mutations occurred evenly throughout the entire PTCH1 protein domain without a hot-spot detected. CONCLUSION Mutations and LOH in PTCH1 were also highly prevalent in Chinese sporadic BCCs. However, UV light plays a less role in causing these mutations, suggesting other potential mechanisms in the development of sporadic BCC in Chinese patients.

Abstract
OBJECTIVE To explore the ultrastructural changes of hepatocyte fibrogenesis in cholelithiasis in biliary tract. METHODS l0 liver biopsies were taken from the patients suffered from gallstone and choledocholithiasis during surgical treatment and the ultrastructural changes were observed under electromicroscope. RESULTS There were plentiful collagenous microfibrils (CMFs) grown within some hepatocytes. These CMFs distributed locally or diffusely in cytoplasm even extended into nucleus. In 7 cases numerous megamitochondrias appeared in several hepatocytes, the inclusions mimicking fibrils could be frequently seen and grew beyond the envelope. Furthermore, typical CMFs could be seen in the large microbodies, and several vesicular or cystic structures similar as fibroblast were presented in marginal areas of the hepatocytes. CONCLUSIONS We deduce that the fibrosed hepatocytes may be remained and take part in the hyperplasia of hepatic fibrous tissue.

Abstract
AIM Previous studies have shown that tenuigenin, a crude extract of Polygala tenuifolia Willd. that is commonly used in traditional Chinese herbal medicine for memory loss, can reduce the secretion of Abeta from cultured cells. However, the mechanism underlying this effect and the active compound derived from tenuigenin is unknown. In this study, a purified component of tenuigenin, tenuifolin, was examined and revealed to be an effective compound in vitro. METHODS Abeta secretion from three sets of COS-7 cells, each carrying a plasmid expressing a different form of APP was examined following the treatment with tenuifolin. Initially, tenuifolin was determined to have no inherent toxicity to either the transfected or wild type cells at the effective concentrations. Cells were then treated with 0.5-2.0 microg mL(-1) tenuifolin for 12 h and their media were examined via an ELISA for Abeta1-40 and Abeta-42. RESULTS We found that treatment with 2.0 microg mL(-1) tenuifolin significantly decreased Abeta secretion from COS-7 cells without altering the ratio of Abeta1-40 and Abeta-42. This effect is most probably due to inhibition of the beta-site APP cleaving enzyme as Abeta secretion was not inhibited from cells expressing the C99 fragment. CONCLUSION Tenuifolin is an effective compound from tenuigenin. We believe that this finding should lead the way for future experiments to determine the exact mechanism for tenuifolin's effect on Abeta secretion.
