Abstract
Objective: To explore the role of transient elastography technology in the assessment of disease staging and treatment in patients with chronic hepatitis B virus (HBV) infection. Methods: Patients who were clinically diagnosed with chronic HBV infection at Beijing Tsinghua Changgung Hospital from January 2018 to December 2021 was collected. Liver stiffness measurement (LSM) examination was performed more than once by transient elastography. The count data were expressed as cases (%) and the χ (2) test was made. Fisher's exact test was used with theoretical frequency less than 5. The measurement data between two groups was compared by t-test. Multiple groups were compared with an analysis of variance. Results: 1 055 patients were included in this study, including 669 (63.4%) males and 386 (36.6%) females. 757 (71.8%) patients were untreated. Among the untreated patients, the LSM value in the immune clearance (10.2 ± 3.8) kPa (187 cases, 40.4%), and the reactivation stages (9.1 ± 3.4) kPa (114 cases, 24.6%) was significantly higher than that in the immune tolerance (8.7 ± 3.6) kPa (78 cases, 16.8%) and immune control stages (8.4 ± 3.5) KPa (84 cases, 18.1%), and the difference between the four groups was statistically significant (F = 5.31 and P = 0.03). With ALT (male: 30 U/L, female: 19 U/L) as defined the normal value, the LSM value in the immune tolerance and the immune control stages were (5.8 ± 0.9) kPa and (7.1 ± 2.5) kPa, respectively, which were significantly lower than those of patients in the immune tolerance and immune control stages, and the difference was statistically significant (P < 0.01). There were 294 (38.8%) patients with uncertain period, excluding patients with fatty liver. Patients with uncertain periods were divided into four gray zone (GZ) groups: immune tolerance stage: LSM (5.1 ± 1.3) kPa was significantly lower than GZ-A (6.5 ± 2.4) kPa, t = 2.06, P = 0.03, and the difference was statistically significant; immune control stage: LSM was (5.6 ± 1.5) kPa, which was also lower than GZ-C (6.8 ± 1.3) kPa, t = 3.08, P = 0.02, and the difference was statistically significant; immune clearance stage: LSM > 8.0 kPa. LSM values showed a year-by-year reduction in patients with expanded indications who started antiviral treatment and were followed up for three years. Conclusion: The LSM value is significantly lower after the decrease of the defined high-normal ALT value in patients with the immune tolerance and immune control stages of chronic HBV infection. The LSM values of GZ-A and GZ-C in the uncertain periods of chronic HBV infection are higher than those of patients in the immune tolerance and immune control stages.

Abstract
Objective: To analyze the clinical characteristics of oral candidiasis (OC) in in-patients with rheumatism, in order to provide theoretical basis for the prevention and treatment of OC in rheumatism patients. Methods: One thousand eight hundred and eight in-patients were recruited in the Department of Rheumatology, the Second Hospital of Shanxi Medical University from January 2017 to December 2017. The patients included 607 males and 1 201 females. Their average age was (49.5±15.5) years old with a ranging from 14 to 81 years. According to occurrence of OC or not, the patients were divided into OC group and non-OC group. The differences of general data, primary diseases, laboratory examinations, usage of glucocorticoid and immunosuppressant therapy were compared between the two groups, and the risk factors of OC occurrence were analyzed. Results: Two hundred and sixty-nine patients had OC and 1 539 patients had no OC. Age [(54.9±14.7) years], duration of illness [(9.4±4.4) years] and hospital stay [(15.3±5.7) d] in OC group were significantly longer than those in non-OC group. OC incidence in patients with connective tissue disease (CTD) [17.40% (193/1 109)] was higher than that in non-CTD patients [10.87% (75/699)] (P<0.001). OC most likely occurred in patients with such CTD as Sjögren syndrome (SS) and Behcet syndrome. OC incidence in non-CTD patients with osteoarthritis (OA) was highest. The salivary flow rate in OC group [(0.65±0.45) ml/min] was significantly lower than that in non-OC group [(0.78± 0.39) ml/min] (t=2.394, P=0.017). There was no statistical differences in other laboratory examinations between the two groups, including white blood cells (WBC), lymphocyte, platelet count, liver function, renal function, erythrocyte sedimentation rate, C-reactive protein, procalcitonin, immunoglobulin G, immunoglobulin M, immunoglobulin A, C(3), C(4) and so on. OC incidence in patients using prednisone≥15 mg/d [17.16% (133/775)] was higher than that in patients using prednisone<15 mg/d [12.53% (94/750)] and patients not using prednisone [14.84% (42/283)] (P<0.05). The incidence of OC in patients with immunosuppressant therapy [16.11% (226/1 403)] was statistically higher than that in non-immunosuppressant patients [10.62% (43/405)] (P<0.01). Logistic regression analysis showed that the risk factors of OC occurrence included primary diseases (P<0.001), age (P<0.001), duration of illness (P=0.001) and duration of hospitalization (P=0.002). Conclusions: OC occurred commonly in rheumatism in-patients, especially in elder patients, patients with long duration of illness and hospital stay. OC incidence in CTD patients is significantly higher than that in non-CTD patients. Glucocorticoid and immunosuppressant therapy might significantly reduce the anti-fungal immunity of the patients.

Abstract
Abstract
Background
Two-dimensional speckle-tracking echocardiography (2D-STE) for the measurement of circumferential ascending thoracic aortic strain (CAAS) in healthy adults is not elucidated. We aimed to establish normal adult STE-derived CAAS and to evaluate associations with age, gender and other physiologic parameters.
Methods
One hundred eighty-one healthy subjects aged 24–75 were prospectively gathered and examined with two-dimensional echocardiography. The global peak CAAS was the parameter used, and an average of six segments of arterial wall deformation was calculated. The corrected CAAS was calculated as the global CAAS/pulse pressure (PP). Aortic stiffness (β2) index was assessed according to ln(Ps/Pd)/CAAS.
Results
We included 171 healthy subjects (age 44.3±10.9 years, 50% female, CAAS16.0±6.9%). The CAAS was independently predicted by age (β=−0.387, P<0.001), and gender (β=−2.701, P=0.001). The corrected CAAS was independently predicted by age (β=−0.009, P<0.001), SAC (β=−0.206, P<0.001) and gender (β=−0.068, P=0.001). The β2 index was independently predicted by age (β=0.136, P<0.001), and PP (β=0.059, P=0.007).
Conclusion
CAAS using 2D-STE can be performed on a clinical basis and may become an important method for the assessment of aortic mechanical parameter. Age, gender and LV afterload-related variables were the most import determinants of 2D-STE global CAAS. Therefore, these factors should be taken into account for strain interpretation in clinical practice.

Abstract
BACKGROUND Excretory/secretory products (ESPs) released by parasites influence the development and functions of host dendritic cells (DCs). However, little is known about changes of DNA (hydroxy)methylation on DC development during Fasciola gigantica infection. The present study aimed to investigate whether F. gigantica ESPs (FgESPs) affects the development and functions of buffalo DCs through altering the DNA (hydroxy)methylation of DCs. METHODS Buffalo DCs were prepared from peripheral blood mononuclear cells (PBMCs) and characterized using scanning and transmission electron microscopy (SEM/TEM) and quantitative reverse transcriptional PCR (qRT-RCR). DCs were treated with 200 μg/ml of FgESPs in vitro, following DNA extraction. The DNA methylome and hydroxymethylome were profiled based on (hydroxy)methylated DNA immunoprecipitation sequencing [(h)MeDIP-Seq] and bioinformatics analyses. qRT-RCR was also performed to assess the gene transcription levels of interest. RESULTS FgESPs markedly suppressed DC maturation evidenced by morphological changes and downregulated gene expression of CD1a and MHC II. Totals of 5432 and 360 genes with significant changes in the 5-methylcytosine (5-mC) and the 5-hydroxymethylcytosine (5-hmC) levels, respectively, were identified in buffalo DCs in response to FgESPs challenge. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis revealed that these differentially expressed genes were highly enriched in pathways associated with immune response. Some cancer-related pathways were also indicated. There were 111 genes demonstrating changes in both 5-mC and 5-hmC levels, 12 of which were interconnected and enriched in 12 pathways. The transcription of hypermethylated genes TLR2, TLR4 and IL-12B were downregulated or in a decreasing trend, while the mRNA level of high-hydroxymethylated TNF gene was upregulated in buffalo DCs post-exposure to FgESPs in vitro. CONCLUSIONS To our knowledge, the present study provides for the first time a unique genome-wide profile of DNA (hydroxy)methylation for DCs that interact with FgESPs, and suggests a possible mechanism of FgESPs in suppressing DC maturation and functions that are involved in TLR signaling.

Abstract
Objective: To analyze and summarize the surgical experience of robotic-assisted laparoscopic partial nephrectomy (RAPN) for treating renal hilar tumors, and assess the efficacy and safety of this surgery. Methods: The clinical data of 22 renal hilar tumor patients who underwent RAPN in Sir Run Run Shaw Hospital, Zhejiang University School of Medicine between September 2015 and September 2017 was analyzed. The patients included 19 males and 3 females, with an average age of (55.6 ±13.0) years old and the age range was 28-75 years. In 13 cases, the tumors were in left kidney, and 9 in the right. There were 10 large tumors (>4 cm diameter), the average tumor size was (3.7±1.9) cm. Preoperative glomerular filtration rate was normal in all cases. Results: The surgery was successfully finished in all of the cases, with no conversion to open surgery. The mean duration of the surgery was 80-270 min, with an average of (134.7±44.5) min. The blood loss was 80-500 ml, with an average of (135.9±130.7) ml, and none of the cases needed intraoperative blood transfusion. The warm ischemia time was 8-25 min, with an average of (18.2±4.0) min. The postoperative length of hospitalization was 7-23 d, with an average of (11.5±4.1) d. Serious gross hematuria occurred in 1 patient, and paroxysmal atrial fibrillation occurred in 1 patient after surgery. The post-operative pathology showed renal clear cell carcinoma in 18 cases, papillary renal cell carcinoma in 2 cases, chromophobe cell carcinoma in 1 case and well differentiated neuroendocrine tumor in 1 case. The tumor resection margin was negative in all cases. Neither local recurrence nor metastasis was observed during a follow-up of 1 to 15 months. Renal function of all the patients was in normal range. Conclusion: RAPN is a safe, useful approach and a minimally invasive operation for treating renal hilar tumors and it owns crucial advantages in complete and accurate resection of the renal hilar tumors and the reconstruction of the kidney.

Abstract
OBJECTIVE To study the effect of reserving articular capsule and traditional total hip replacement for old patients with unstable femoral neck fractures. METHODS From January 2010 to January 2015, one hundred and twenty patients with femoral neck fracture were retrospective review. Among them, sixty patients were treated with total hip arthroplasty reserving articular capsule, the others were treated with traditional total hip arthroplasty without reserving articular capsule. The gender of reserving articular capsule group and traditional group were (male/female) 34/26, 31/29 respectively; the age were (73.4±4.4), (72.3±4.1) years old, respectively. All patients were followed up for six months, the operation time, blood loss, length of stay, incidence of postoperative complications, incidence of postoperative hip dislocation and hip Harris score of the two groups were observed. RESULTS The operative time of the reserving articular capsule group and traditional group were (95.68±6.90), (93.39±7.90) min (P>0.05), and the blood loss were (998.78±15.20), (1 000.25±16.80) ml (P>0.05). The time for hospital stay were (10.74±2.90), (13.25±2.20) days(P<0.05). The Harris scores were 58.53±5.10, 49.38±4.90(P<0.05) at 1 month after operation;91.08±7.50, 90.74±7.10(P>0.05) at 6 months after operation. CONCLUSIONS The method of reserving auricular capsule can not increase the operative time and the blood loss. But it has a favorable effect on decreasing the hospital stay, complication, the rate of early dislocation of the hip joint, improving the function of hip joint.

Abstract
OBJECTIVES To introduce the application of the J-Valve™ system in elderly patients with predominant aortic incompetence without significant valve calcification, and to evaluate its feasibility. METHODS From April 2014 to July 2015, 33 cases of transapical implantation of J-Valve™ were performed in Department of Cardiac Surgery, Zhongshan Hospital, Fudan University. Sixteen of these patients were diagnosed as predominant aortic incompetence without significant valve calcification. There were 11 male and 5 female patients aged from 61 to 84 years, with a mean age of (76±6) years. All patients had symptoms of left ventricular dysfunction for at least 3 months. They were considered to be prohibitive for surgical valve replacement (logistic European system for cardiac operative risk evaluation: 22.2% to 44.4%, mean 27%±6% after evaluation by an interdisciplinary heart team. The J-Valve™ system was applied in transapical transcatheter aortic valve replacement for patients. The multi-slice CT was performed before discharge. Clinical evaluation including patients' history, symptoms and New York Heart Association classification and echocardiogram evaluation were performed before discharge, 1(st) month, 3(th) month and 12(th) month after the operation respectively. RESULTS Implantations were successful in all patients. One patient died from moderate paravalvular leak which led to multi-organ failure during the hospital stay. The mean time of postoperative hospital stay of the other 15 patients was (6.1±1.3) days. The 15 patients were followed by 174 to 410 days, with a median time of 188 days. Only two patients had trivial prosthetic valve incompetence, the other 13 patients had no prosthetic valve incompetence; two patients had no paravavular leak and the other 13 patients had paravavular leak of no more than moderate grade. There were no major complication or mortality during the follow-up. CONCLUSIONS The transapical implantation of the J-Valve™ system in high risk elderly patients with predominant aortic incompetence is feasible.The early postoperative outcome is satisfactory.

Abstract
Macrophage migration inhibitory factor (MIF) is a well-described proinflammatory mediator. MIF overexpression has been observed in many tumors and is implicated in oncogenic transformation and tumor progression. However, the molecular mechanisms responsible for regulating MIF expression remain poorly understood. In this study, we showed that the transcriptional repressor HBP1 (HMG box-containing protein 1) negatively regulates MIF expression. We first identified a large high-affinity HBP1 DNA-binding element at positions -811 to -792 from the transcriptional start site within the MIF promoter by computer analysis. Reporter analyses showed that this element was required for HBP1-mediated transcriptional repression. Furthermore, HBP1 associated with the MIF promoter in vivo and repressed endogenous MIF gene expression. Consistent with HBP1-mediated repression of MIF, low levels of HBP1 expression were associated with high levels of MIF expression in prostate cancer samples. Importantly, HBP1-mediated repression of MIF inhibited tumorigenic growth and invasion, and the repressive effect of HBP1 on tumorigenic growth and invasion could be partially rescued by the addition of recombinant MIF to the culture medium. Finally, prostate tumor samples with low HBP1 and high MIF expression were associated with a significant decrease in relapse-free survival. Taken together, these results indicated that HBP1 directly inhibited MIF gene transcription, and suggested that the loss of HBP1 expression or activity may contribute to the upregulation of MIF expression in prostate tumor tissue.

Abstract
We investigated the effectiveness of celecoxib in reducing symptoms in patients with difficult chronic pelvic pain syndrome (CPPS), NIH category IIIA. Sixty-four patients with category IIIA CPPS were randomized into two groups of 32 subjects each. One group was treated with celecoxib (200 mg daily) and the other with placebo. All patients underwent treatment for 6 weeks and were evaluated clinically before (baseline) and after 1, 2, 4, 6, and 8 weeks of treatment. The evaluation included the NIH Chronic Prostatitis Symptom Index (NIH-CPSI) and a subjective global assessment (SGA). Repeated measures analysis of variance was used to evaluate treatment and time effects and their interaction. A decrease (means +/- SD) in total NIH-CPSI score from 23.91 +/- 5.27 to 15.88 +/- 2.51 in the celecoxib group and from 24.25 +/- 5.09 to 19.50 +/- 2.50 in the placebo group was observed during treatment (0 to 6 weeks). A statistically significant decrease was observed in pain subscore (P < 0.006), quality of life subscore (P < 0.032) and total NIH-CPSI score (P < 0.015) after 2, 4 and 6 weeks, but not in urinary subscore. In addition, 38% of the celecoxib and 13% of the placebo subjects had at least a moderate improvement in SGA. The trend was similar for the NIH-CPSI scores. However, the response to treatment in terms of total NIH-CPSI score or subscore was not significantly different from placebo after interruption of treatment for 2 weeks. Our results show that celecoxib provides significant symptomatic improvement limited to the duration of the therapy in patients with difficult category IIIA CPPS compared to placebo.

Abstract
STUDY DESIGN This comparative study was conducted on 19 patients (13 men and 6 women) with lumbar disc herniation (LDH). The histologic and histochemical differences and changes in the back muscles of the diseased and normal sides were evaluated. OBJECTIVES To determine the histologic differences in the back muscles between the diseased and normal sides in lumbar disc herniation. SUMMARY OF BACKGROUND DATA The morphologic changes of back muscles between the diseased and normal sides in lumbar disc herniation were examined using histologic and histochemical methods. Few studies have reported the difference in these changes based on quantitative analyses. METHODS All samples were harvested bilaterally from the multifidus muscle at the level of L4-L5 or L5-S1 in patients with lumbar disc herniation and then were examined by histologic and histochemical methods (hematoxylin-eosin, Gomori trichrome, NADH-TR, and ATPase stains). The percentage, cross-sectional area (CSA), and lesser diameter (LD) of muscle fibers were measured using computerized image analysis. The Wilcoxon, paired t, Kruskal Wallis, and Fisher tests were used for statistical analysis. RESULTS Both Type I and II fibers in the diseased side were significantly smaller than those from the normal side. In the diseased side, the potential strength of Type II fibers was weakened. Some pathologic changes (fiber type grouping, small angulated fibers, group atrophy, moth-eaten appearance, and internal nuclei, etc.) in the diseased side were more obvious than those in the normal side. When the straight leg raising test results were abnormal, both Type I and II fibers in the diseased side were smaller than those in the normal side. The Type I fibers of the diseased side were significantly smaller when the patients had symptoms of central low back pain. The size of the Type I fibers as well as of the Type II fibers did not differ between the diseased and normal sides in patients with unilateral and bilateral low back pain. CONCLUSIONS The present study indicated that there were differences in the characteristics of the multifidus muscle between the diseased and normal sides in patients with lumbar disc herniation. The changes in muscle characteristics primarily were related to the disc protrusion. In addition, different locations of the low back pain seemed to cause different secondary effects on the muscle characteristics.

Abstract
Successful cytogenetic analysis was performed on 27 samples from 25 patients with RCC, including 7 of 11 tumors studied and 20 cell lines. Clonal chromosomal abnormalities were detected in all 27 samples. The most frequently involved chromosomes were 7, 1, 3, 9, and the Y (20, 17, 17, 14, and 10 cases, respectively). Polysomy 7 or rearrangement of 7q was seen in 80% (20/25) of the patients, and loss or rearrangement of 3p was seen in 48% (12/25); of the latter, four patients had loss of the whole chromosome and 10 patients had deletions or translocations involving 3p, with breakpoints at either 3p11-14 or 3p21-23 (5/7 translocation breakpoints were at 3p21-23). Loss of the sex chromosomes was seen in 15 patients, including -Y in 10/22 males. Other clonal changes included structural abnormalities of chromosome 1 centromere and the long arm, breakpoints at or near the centromere of chromosome 9 (10 patients), polysomy 16, monosomy 17, polysomy 20, and monosomy 22. With the exception of chromosome 3p loss, which was primarily confined to the nonpapillary cases, no specific clonal abnormality was noted for any particular subtype of RCC. Trisomy or tetrasomy 7 and -Y were seen in all subtypes of renal cell carcinoma.

Abstract
Few reports correlating specific cytogenetic abnormalities with distinct subtypes of lymphoma have performed serial studies at diagnosis and at tumor recurrence or progression. In our file of 325 cytogenetically analyzed non-Hodgkin's lymphoma (NHL) patients studied over the past decade, 43 had serial biopsies, 39 of whom had at least two successful preparations; of the 43, nine had one and 32 had two or more cytogenetically abnormal specimens. In this study, we correlated cytogenetic, histopathologic, molecular, and clinical parameters. Patients with low-grade lymphomas were as likely as patients with intermediate- or high-grade lymphomas to acquire new chromosomal abnormalities with time (16 of 23 patients as compared with 7 of 16; P2 = .11, chi 2 test). In four patients, originally diagnosed indolent disease progressed to aggressive disease; all had t(14;18), all gained additional chromosomal abnormalities with disease progression, and three of the four expressed abnormalities associated with disease progression and/or short survival: der(18), +7, and/or +12. Cytogenetic results from early disease were compared with those obtained later in disease: in the t(14;18) group, the most common abnormalities were +7 (eight patients) and der(18) (five patients), both seen later in disease. The most common abnormalities in patients without t(14;18) were 6q deletions; they were seen in both early and late disease and were associated with significantly shorter survivals (P2 = .0014) compared with all patients without 6q deletions. Secondary chromosomal abnormalities, observed after at least one previous abnormal study, were seen in 19 of 22 t(14;18) patients and in 11 of 21 patients without t(14;18) and were associated with a poor survival (P2 = .13) compared with patients without any secondary chromosomal abnormalities. Chromosome 1 abnormalities were seen in almost half of the patients and were observed in initial specimens and early in disease as well as late in disease and as secondary abnormalities; 1q involvement was more frequent than 1p (15 versus eight patients) and was significantly associated with poor survival only in patients with intermediate-/high-grade disease; the most common breakpoints were 1q21-q22 (nine patients) and 1p36 (six patients). Breakpoints at 2q21 and 3q27-q29 were limited to patients with t(14;18) and were almost exclusively secondary in nature. Molecular studies in 24 of our patients showed discrepancies with the cytogenetic results in only three patients: two had t(14;18) but no molecular rearrangements while two patients had no visible t(14;18) but were positive for major breakpoint region (MBR) rearrangement. The presence of MBR or minor breakpoint cluster (MCR) rearrangement had no apparent effect on survival.(ABSTRACT TRUNCATED AT 400 WORDS)

Abstract
Cytogenetic studies have been reported in fewer than 20 patients with lymphoma of mucosa associated lymphoid tissue (MALT). Two patients with this disease at the Clinical Center, National Institutes of health had numerical and structural chromosome abnormalities, including +12 in both cases. The clonal karyotypes observed were 48-49,XX,t(2;8)(q33;p23), +3, -10,del(10)(q23), +12, +18 [cp] and 47,X,-X,i(6p), +7, +inv(12)(p13q13). Review of cytogenetic studies from published data showed that all cases of MALT lymphoma reported to date also have both numerical and structural chromosome abnormalities, the most frequent being numerical involvement of chromosomes 3, 7, and 12. Identification of a clonal abnormality can help establish the diagnosis when differential diagnosis includes atypical hyperplasia. Although trisomy 12 has been associated with a poor prognosis in B-cell chronic lymphocytic lymphoma (B-CLL), both these patients with MALT lymphoma have had long survival: 8 and 11 years, respectively.

Abstract
rhoA encodes a ras-related GTP-binding protein that is thought to play a role in cytoskeletal organization. Recent evidence has suggested both that rhoA could act either as a dominant oncogene, since transfection of both normal and activated rho genes confer a transformed phenotype on fibroblast cells in culture, or as a recessive tumor suppressor gene, by virtue, in part, of its chromosomal location at 3p21, a site deleted in many human malignancies. In either case, a role for rhoA in the oncogenesis of human tumors would be supported by the finding of rhoA mutations in tumors. We therefore examined human tumors and cell lines for mutations in the protein coding regions of rhoA by RNAase protection analysis. We first examined the expression of rhoA in renal cell carcinoma cell lines in which 3p21 was heterozygously deleted or retained. We found no evidence for rhoA mutations in these specimens. We also examined RNA from lung, breast, colon or ovarian tumors and also found no evidence of activating rhoA mutations. Furthermore, there was no relation between the level of rhoA mRNA expression and the presence or absence of 3p21 deletions in the renal cell carcinoma specimens. Thus, although rhoA has transforming potential in vitro, there is no evidence that it is activated by mutation in human malignancies, or that it could act as a tumor suppressor gene in tumors in which 3p21 is deleted.

Abstract
HTLV-I, II and HIV-1, 2 are T-cell tropic viruses, all belonging to the retrovirus family. These viruses are transmitted horizontally by intimate contact or through blood products. The study of chromosomal changes in these T cells may enhance our understanding of the nature and mechanism of these viral infections. However, because of the cytopathic effect of these viruses on T cells, the direct observation of abnormalities in these cells is sometimes difficult. We performed chromosomal analysis on six HTLV-I cell lines from patients with HTLV-I-positive leukemia/lymphoma, one HTLV-I variant cell line, and two HTLV-II-positive cell lines. The results of these studies were compared with the findings in an earlier (published) study of direct preparations and short-term cultures of cells from 11 HTLV-I-positive NIH patients. Our study also included cytogenetic analysis of seven established cell lines and six normal peripheral bloods infected in vitro with the HTLV-IIIB strain of HIV-1 (five cell lines and six bloods) or HIV-2 (two lines); all were studied both before and after viral infection. The results showed that all six HTLV-I cell lines and the variant cell line had multiple chromosomal changes: three lines had deletions of chromosome 6, with breakpoints between q21 and q25. Nine of the 11 NIH patients with HTLV-I had clonal abnormalities, and six of these nine had chromosome 6 deletions with breakpoints ranging from band q11 to band q23. The high incidence of 6q involvement may be of considerable significance in this clinical subgroup of HTLV-I patients. The two HTLV-II cell lines were established from patients suffering from HTLV-II infection. Both of these cell lines had translocations of chromosome 21 at p11, and both had extra copies of chromosome 20; no known oncogenes or receptors are located on these two chromosomes. Chromosome 17 was the chromosome most frequently involved (three lines) in the five HIV-1-infected cell lines, followed by chromosomes 3 and 21; it is of interest that NGL (also known as C-ERBB2 or NEU oncogene), CD7 (a lymphocyte antigen), HTLV-1 receptor, NGFR (nerve growth factor receptor), and MIC6 are all cell surface antigens coded by genes on chromosome 17q. No specific chromosome abnormalities were found in the normal blood samples infected with HIV-1, and no unique chromosome changes were noted in the two cell lines infected with HIV-2; however, the infected H9 line had a chromosome 17 abnormality, a translocation involving band 17p11.

Abstract
Flavoxate is a smooth muscle relaxant widely used to treat urgency and urge incontinence. It has been used in an unblinded, uncontrolled clinical trial in 14 urology departments in universities and major hospitals in the People's Republic of China involving 361 patients with urgency/incontinence of various types. Patients were given 200 mg three times daily, orally, for 2 weeks, although 33 patients received a daily dosage of 1200 mg. Frequency, urgency, dysuria, nocturia and incontinence were assessed and scored clinically prior to and after treatment. Three departments also included urodynamic investigations, e.g. monitoring of the end-residual volume. Results from 336 evaluable patients indicate that 228 (67%) were completely cured of urgency/incontinence symptoms, 66 (20%) were improved and 42 (13%) patients were unchanged. Flavoxate was also effective in 77.4% of patients refractory to previous anti-cholinergic treatment. Treatment did not increase the end-residual volume and adverse events occurred only in four (1.3%) patients, two (0.6%) of which discontinued the therapy. The 1200 mg dose produced a complete cure in 82% of patients and improvement in the remaining 18%, with no side-effects. In conclusion, flavoxate is an effective and well tolerated treatment for urgency/incontinence of various causes.

Abstract
It is difficult to diagnose malignant chromaffinoma among the endocrine tumors. At present, using biochemical and histochemical methods, tumors with the estrogen or nonestrogen target organs have been proved to possess estradiol receptors. In this paper, binding of steroid to active chromaffinoma was observed using synthesized 4-amino-N-fluorescent isothiocyanate-17 beta-estradiol (4 NHEF) as a probe. Benign and malignant chromaffinoma may be differentiated by the fluorescence difference. Under the same condition, the binding of fluorescence estradiol to the normal adrenal cells was weak. It was stronger in the majority of benign chromaffinoma, but was very strong in the malignant type. In a case of malignant chromaffinoma, the adrenal was excised first which was diagnosed as a benign tumor by pathological examination. But it was malignant by 4 NHEF stain. After two days, the patient's blood pressure became elevated and a second operation had to be done. Still, the tumor cells were benign by pathological examination. This chromaffinoma was finally diagnosed by fluorescence labelled estradiol which is more sensitive than pathology.
