Abstract
Objective: To analyze the clinicopathologic characteristics and prognosis of testicular diffuse large B-cell lymphoma (DLBCL) . Methods: A retrospective analysis was performed on 68 patients with testicular DLBCL admitted to Ruijin Hospital affiliated to Shanghai Jiao Tong University School of Medicine from October 2001 to April 2020. The gene mutation profile was evaluated by targeted sequencing (55 lymphoma-related genes) , and prognostic factors were analyzed. Results: A total of 68 patients were included, of whom 45 (66.2% ) had primary testicular DLBCL and 23 (33.8% ) had secondary testicular DLBCL. The proportion of secondary testicular DLBCL patients with Ann Arbor stage Ⅲ-Ⅳ (P<0.001) , elevated LDH (P<0.001) , ECOG score ≥ 2 points (P=0.005) , and IPI score 3-5 points (P<0.001) is higher than that of primary testicular DLBCL patients. Sixty-two (91% ) patients received rituximab in combination with cyclophosphamide, adriamycin, vincristine, and prednisone (R-CHOP) -based first-line regimen, whereas 54 cases (79% ) underwent orchiectomy prior to chemotherapy. Patients with secondary testicular DLBCL had a lower estimated 5-year progression-free survival (PFS) rate (16.5% vs 68.1% , P<0.001) and 5-year overall survival (OS) rate (63.4% vs 74.9% , P=0.008) than those with primary testicular DLBCL, and their complete remission rate (57% vs 91% , P=0.003) was also lower than that of primary testicular DLBCL. The ECOG scores of ≥2 (PFS: P=0.018; OS: P<0.001) , Ann Arbor stages Ⅲ-Ⅳ (PFS: P<0.001; OS: P=0.018) , increased LDH levels (PFS: P=0.015; OS: P=0.006) , and multiple extra-nodal involvements (PFS: P<0.001; OS: P=0.013) were poor prognostic factors in testicular DLBCL. Targeted sequencing data in 20 patients with testicular DLBCL showed that the mutation frequencies of ≥20% were PIM1 (12 cases, 60% ) , MYD88 (11 cases, 55% ) , CD79B (9 cases, 45% ) , CREBBP (5 cases, 25% ) , KMT2D (5 cases, 25% ) , ATM (4 cases, 20% ) , and BTG2 (4 cases, 20% ) . The frequency of mutations in KMT2D in patients with secondary testicular DLBCL was higher than that in patients with primary testicular DLBCL (66.7% vs 7.1% , P=0.014) and was associated with a lower 5-year PFS rate in patients with testicular DLBCL (P=0.019) . Conclusion: Patients with secondary testicular DLBCL had worse PFS and OS than those with primary testicular DLBCL. The ECOG scores of ≥2, Ann Arbor stages Ⅲ-Ⅳ, increased LDH levels, and multiple extra-nodal involvements were poor prognostic factors in testicular DLBCL. PIM1, MYD88, CD79B, CREBBP, KMT2D, ATM, and BTG2 were commonly mutated genes in testicular DLBCL, and the prognosis of patients with KMT2D mutations was poor.

Abstract
Objective: To analyze the clinical characteristics and prognosis of primary and secondary pancreatic diffuse large B-cell lymphoma (DLBCL) . Methods: Clinical data of patients with pancreatic DLBCL admitted at Shanghai Rui Jin Hospital affiliated with Shanghai Jiao Tong University School of Medicine from April 2003 to June 2020 were analyzed. Gene mutation profiles were evaluated by targeted sequencing (55 lymphoma-related genes). Univariate and multivariate Cox regression models were used to evaluate the prognostic factors of overall survival (OS) and progression-free survival (PFS) . Results: Overall, 80 patients were included; 12 patients had primary pancreatic DLBCL (PPDLBCL), and 68 patients had secondary pancreatic DLBCL (SPDLBCL). Compared with those with PPDLBCL, patients with SPDLBCL had a higher number of affected extranodal sites (P<0.001) and had higher IPI scores (P=0.013). There was no significant difference in the OS (P=0.120) and PFS (P=0.067) between the two groups. Multivariate analysis indicated that IPI intermediate-high/high risk (P=0.025) and double expressor (DE) (P=0.017) were independent adverse prognostic factors of OS in patients with pancreatic DLBCL. IPI intermediate-high/high risk (P=0.021) was an independent adverse prognostic factor of PFS in patients with pancreatic DLBCL. Targeted sequencing of 29 patients showed that the mutation frequency of PIM1, SGK1, BTG2, FAS, MYC, and MYD88 in patients with pancreatic DLBCL were all >20%. PIM1 (P=0.006 for OS, P=0.032 for PFS) and MYD88 (P=0.001 for OS, P=0.017 for PFS) mutations were associated with poor OS and PFS in patients with SPDLBCL. Conclusion: There was no significant difference in the OS and PFS between patients with PPDLBCL and those with SPDLBCL. IPI intermediate-high/high risk and DE were adverse prognostic factors of pancreatic DLBCL. PIM1, SGK1, BTG2, FAS, MYC, and MYD88 were common mutations in pancreatic DLBCL. PIM1 and MYD88 mutations indicated worse prognosis.

Abstract
OBJECTIVE To investigate the application of high offset femoral stem prosthesis in primary total hip arthroplasty. METHODS From January 2015 to June 2017, 51 patients with unilateral hip diseases who underwent primary total hip arthroplasty with Corail high offset femoral stem prosthesis(KHO type) were selected for retrospective study, including 20 females and 31 males;the age ranged from 21 to 71 years old with an average of(50.8±13.3) years old. The abduction arm, femoral offset, acetabular offset and the length of lower limbs were measured on the positive X-ray film of hip joint after operation. Harris scores before and after operation and related complications were recorded, and the stability of prosthesis was analyzed. RESULTS The femoral offset, combined offset and abduction arm of the affected side were significantly greater than those of the healthy side(P<0.05). There was no significant difference in acetabular offset between the affected side and the healthy side (P>0.05). The femoral offset of 17 hips (33.3%) was reconstructed normally, of which 15 cases (88.2%) had equal length of both lower limbs. The femoral offset of 34 hips (66.7%) was greater than that of the healthy side, and 34 cases (100%) had equal length of both lower limbs. All 51 patients were followed up for(42.3±7.3) months. The Harris score increased from 38.0±7.6 before operation to 92.1±3.1 at the final follow-up(P<0.001). CONCLUSION Although the high offset Corail prosthesis can not normally reconstruct the femoral offset in unilateral primary total hip arthroplasty, it does not affect the reconstruction of the length of lower limbs and the stability of the prosthesis.

Abstract
Objective: To compare the clinical efficacy of a recombinant bovine basic fibroblast growth factor (rb-bFGF) gel and a gel matrix in the treatment of moderate dry eye. Methods: It was a prospective random double-blind controlled study. One hundred patients diagnosed as moderate dry eye in Eye Institute and Affiliated Xiamen Eye Center of Xiamen University, Union Hospital Affiliated to Tongji Medical College of Huazhong University of Science and Technology, Beijing Tongren Hospital, Capital Medical University, Eye & ENT Hospital of Fudan University and Zhongshan Ophthalmic Center from August 2015 to April 2019 were divided into two groups: experimental group and control group. Two groups of patients were allocated to receive either a rb-bFGF gel or a gel matrix 4 times per day for 4 weeks. Subjective symptoms, break-up time of the tear film (BUT), Schirmer Ⅰ test (SⅠt) and corneal fluorescein sodium staining were assessed at baseline, 2 and 4 weeks after treatment. Bulbar impression cytology was evaluated at baseline and 4 weeks after treatment. Irritation of the rb-bFGF gel and the gel matrix was estimated after treatment. T test, Wilcoxon signed-rank test or Mann-Whitney U test was used for quantitative data, and Chi-square test was used for enumerative data. Results: Eighty-four subjects were included for statistical analyses after the exclusion of 16 subjects who were lost for followup, with an age of 43±14 years. There were 42 cases in the experimental group and the control group, respectively. There was no statistically significant difference between the two groups in demographic baseline characteristics before treatment (P>0.05). The total score of subjective symptoms was 7.17±3.60 and 5.95±3.25 at 2 and 4 weeks after therapy in the experimental group, which were lower than 9.48±3.88 before treatment (t=6.226, 6.563; both P<0.05); in the control group, it was 7.01±3.25 and 6.32±3.85 at 2 and 4 weeks after treatment, with a significant reduction in comparison with that before treatment (9.15±3.58; t=4.693, 4.726; both P<0.05). The median (lower quartile, upper quartile) BUT was 4.00 (2.40, 5.00) s and 4.64 (3.00, 5.00) s at 2 and 4 weeks after therapy in the experimental group, which were longer than 3.72 (2.00, 4.39) s before treatment (Z=-2.485, -3.152; both P<0.05). The BUT was 4.41 (2.79, 5.12) s at 2 weeks after therapy in the control group, which was of no statistical difference compared with 3.89 (2.09, 4.25) s before treatment (Z=-1.953, P>0.05). The BUT was 5.21 (3.00, 5.02) s at 4 weeks after therapy in the control group, which was longer than that before treatment (Z=-2.485, P<0.05). The SⅠt score was 7.31 (3.75, 10.00) mm and 8.50 (4.00, 11.00) mm at 2 and 4 weeks after therapy in the experimental group, which were significantly higher than 6.69 (2.00, 8.13) mm before treatment (Z=-2.031, -2.236; both P<0.05); in the control group, it was 6.82 (2.00, 8.25) mm and 6.86 (3.00, 9.25) mm at 2 and 4 weeks after therapy, which were not significantly increased compared with 6.50 (2.00, 7.75) mm before treatment (Z=-0.179, -1.161; both P>0.05). The corneal fluorescein sodium staining points were 5.00 (2.00, 5.00) and 3.71 (0.00, 5.00) at 2 and 4 weeks after therapy in the experimental group, which were significantly lower than 7.10 (5.00, 7.00) before treatment (t=-2.895, -4.639; both P<0.05); those in the control group were 5.52 (0.00, 7.00) and 6.19 (0.75, 6.25) at 2 and 4 weeks after treatment, with a significant reduction in comparison with 8.90 (5.00, 10.50) before treatment (t=-2.776, -1.991; both P<0.05). The differences in the average total score of subjective symptoms, BUT, SIt, and corneal fluorescein sodium staining points between both groups were not statistically significant at each time point. The impression cytology grade was decreased from 1.72 (1.00, 2.00) before treatment to 0.94 (0.00, 2.00) at 4 weeks after therapy in the experimental group (Z=-2.803, P<0.05). The staining grade of conjunctival imprinted cells in the control group was 1.42 (1.00, 2.00) at 4 weeks, which showed no statistical significance compared with 1.56 (1.00, 2.00) before treatment (Z=1.195, P>0.05). The impression cytology grade was significantly reduced in the experimental group compared with the control group at 4 weeks after treatment (Z=-3.308, P<0.05). The number of goblet cells was 10.90 (5.00, 20.00) at 4 weeks after therapy in the experimental group, which was significantly higher than 6.30 (5.00, 8.00) before treatment (Z=-2.383, P<0.05); in the control group, it was 8.36 (4.00, 12.00) at 4 weeks after treatment, with no significant increase in comparison with that before treatment [7.55 (5.00, 11.00)] (Z=-0.095, P>0.05). The number of goblet cells was not significantly increased in the experimental group compared with the control group at 4 weeks after treatment (Z=-1.162, P>0.05). Most patients indicated that the drug was non-irritating, and no patient had intolerable irritation affecting daily lives at 4 weeks after therapy; there was no difference between the two groups (Z=-0.290, P>0.05). Conclusions: Both the rb-bFGF gel and the gel matrix can effectively improve the symptoms and signs of moderate dry eye. However, compared with the gel matrix, the rb-bFGF gel shows obvious advantages in promoting conjunctival epithelial cell repair and increasing the number of goblet cells.

Abstract
This article was published ahead of print on the official website of Chinese Journal of Ophthalmology on April 14, 2020. Currently, it is commonly reported that coronavirus disease 2019 (COVID-19) patients are associated with conjunctival congestion and other symptoms, and the transmission route and high-risk eye diseases and high-risk working status are speculated. Are conjunctival congestion and conjunctiva-related symptoms in patients with 2019 novel coronavirus definitely related to the novel coronavirus? Conjunctival congestion is one of the common clinical signs of various types of conjunctivitis. The symptoms and signs of conjunctivitis in COVID-19 patients may be attributed to a variety of factors. Therefore, conjunctival symptoms should not be linked to 2019 novel coronavirus without evidence. ( Chin J Ophthalmol, 2020, 56: 571-572).

Abstract
Objective: To investigate the efficacy of RCDOP (Rituximab, cyclophosphamide, liposome doxorubicin, vincristine and prednisone) regimen in patients with de novo diffuse large B-cell lymphoma (DLBCL), especially in those patients with multiple extra-nodal involvement or Bulky diseases. Methods: A total of 87 newly diagnosed DLBCL patients who received RCDOP regimen from October 2012 to October 2017 were enrolled into this study. Survival functions were estimated using the Kaplan-Meier method and compared by the log-rank test, and χ(2) tests were used for categorical data. Results: Among the 87 DLBCL patients treated with RCDOP regimen, 81 patients achieved complete remission (CR) or partial remission (PR), with ORR as 93.1%. Patients were further classified into groups, according to the risk factors, such as IPI scores, multiple extra-nodal involvement, bulky disease, age>60, tumor Ki-67>80%, elevated serum LDH level and advanced Ann Arbor stage. The progression-free survival (PFS, P=0.084) and overall survival (OS, P=0.515) had no statistical difference among the IPI low risk (0-1 score) group, intermediate risk (2-3 scores) group and high risk (4-5 scores) group. Similarly, no statistical difference were fou nd in PFS and OS of patients with extra-nodal involvements ≥2 (P=0.303 and P=0.624), with bulky disease (P=0.518 and P=0.466), with age>60 (P=0.600 and P=0.183), with elevated serum LDH level (P=0.054 and P=0.880), with advanced Ann Arbor stage (P=0.075 and P=0.286), and with tumor Ki-67 over 80% (P=0.190 and P=0.109), when compared with those of patients without these risk factors. Conclusion: RCDOP can improve the therapeutic effect and prognosis of DLBCL patients with certain high risk factors, such as intermediate and high IPI risks, multiple extra-nodal involvements, bulky disease, age over 60, elevated LDH level, advanced Ann Arbor stage and tumor Ki-67 over 80%.

Abstract
Objective: To evaluate the efficacy and prognostic factors of second-line regimens for patients with relapsed/refractory diffuse large B-cell lymphoma (DLBCL). Methods: A retrospective analysis was performed in 98 patients with relapsed/refractory DLBCL who were treated with salvage regimens in Rui Jin Hospital from July 2004 to June 2016. Overall response rate (ORR) was evaluated after all treatment finished. Overall survival (OS) was analyzed by Kaplan-Meier method and multivariate by Cox proportional hazards models. Results: There were 60 males and 38 females with a median age of 55.5 (15-77) years. 48 (49.0%) patients responded to chemotherapy, and 32 (32.7%) patients achieved complete remission (CR). Factors affecting ORR were progression disease or refractory/relapse status less than 12 months after diagnosis (χ(2)=5.878, P=0.015) , IPI intermediate-high/high risk (χ(2)=5.930, P=0.015) and NCCN-IPI intermediate-high/high risk (χ(2)=4.961, P=0.026). No significance difference was observed in ORR between germinal-center B-cell type (GCB) and non-GCB (χ(2)=0.660, P=0.417). One-year and 2-year OS rates were 51.0% and 31.5%, with median OS at 13.17 months, respectively. Multivariate analysis indicated NCCN-IPI intermediate-high/high risk[HR=2.176 (95%CI 1.338-3.538) , P=0.002] and response to chemotherapy [HR=0.273 (95%CI 0.165-0.452) , P<0.001] were independent prognostic factors for survival. Conclusion: NCCN-IPI is a valid predictor of outcome for patients with relapse/refractory DLBCL. Response to chemotherapy is an independent prognostic factor for better survival.

Abstract
Objective: To investigate the influence of blue light from visual display terminals (VDTs) on human ocular surface. Methods: Prospective intervention test Thirty volunteers were recruited to watch videos on the same VDT in a dark environment, about 40 cm from the screen. Volunteers were supposed to watch videos in the night shift mode that reduces the amount of blue light for 1 hour. At the same time of the second day, they watched the same videos on the VDT in the normal mode for 1 hour. Tear film break-up time (BUT), corneal fluorescein staining scores, lipid layer thickness (LLT), times of blinking in 19.1 seconds and the ratio of partial blinking in 19.1 seconds were measured before and after each watching. Meanwhile, volunteers were asked to complete a questionnaire about their subjective experience after watching. Results: BUT, corneal fluorescein staining scores and LLT showed no significant decreases in the volunteers after they watched videos on the VDT in the night shift mode [BUT before watching: (8.08±3.15)s, BUT after watching in the night shift mode: (5.31±2.49)s, t=-0.52, P>0.05], but there were significant decreases after they watched videos in the normal mode [BUT after watching in the normal mode: (3.35±1.95) s, t=2.40, P<0.05]. At the same time, there was a significant difference between night shift mode and normal mode[BUT after watching in the night shift mode (5.31±2.49)s, BUT after watching in the normal mode: (3.35±1.95)s, t=3.67, P<0.05). Times of blinking and the ratio of partial blinking in 19.1 seconds were increased modestly after watching in 2 different modes, but there was no significant difference(times of blinking after watching in the night shift mode were 5.55±3.27, times of blinking after watching in the normal mode were 5.93±3.59, t=-0.92, P>0.05). The questionnaire results showed that 70.0%(21) of the volunteers reported mild discomfort including eye dryness, itching, pain, foreign body sensation, redness and asthenopia, 46.7%(14) reported no difference between the 2 modes, 36.7%(11) preferred the night shift mode, 16.6%(5) felt better with the normal mode, and 80.0%(24) would like to try the night shift mode in their daily life. Conclusions: Use of VDTs for a short period of time can lower the stability of tear film. The night shift mode may cause less damage to the ocular surface than the normal mode. High-energy blue light from VDTs can be a risk factor in the ocular surface damage, but the damage is reversible. (Chin J Ophthalmol, 2018, 54: 426-431).

Abstract
Objective: To investigate the imaging diagnosis, treatment and prognosis of primary hepatic neuroendocrine tumors. Methods: The clinical features, imaging manifestations, histopathological and immunohistochemical findings and interventional therapy of 6 patients identified with pathologically confirmed primary hepatic neuroendocrine tumors were retrospectively analyzed, and the related literatures were reviewed. Results: All 6 patients presented with symptoms of abdominal pain. 4 patients had solitary hepatic mass and 2 patients had multiple hepatic masses. Magnetic resonance imaging showed low signal intensity on T1 weighted imaging, high signal intensity on T2 weighted imaging and clear boundary; the arterial phase of enhancement scan was uneven and enhanced, and portal venous phase or delayed phase showed continuous enhancement, surrounded by ring enhanced capsule. A pathological diagnosis was primary neuroendocrine tumor of the liver. After interventional treatment, 6 patients had some therapeutic effects. Among them, 4 patients underwent multiple interventional therapies, followed by 4 years of follow-up has shown satisfactory results. Conclusion: Primary hepatic neuroendocrine tumors are very rare and their imaging manifestations are specific. Eventually, relies on pathological and immunohistochemical diagnosis. Transarterial chemoembolization therapy can bring satisfactory results in the treatment of primary hepatic neuroendocrine tumor.

Abstract
AIM Cryoglobulinaemic glomerulonephritis related to hepatitis B virus (HBV) infection has been rarely reported. The aim of this study was to investigate the clinical features, renal biopsy findings in patients with HBV-associated cryoglobulinaemia. METHODS Twelve patients with HBV-associated cryoglobulinaemia were identified in this study. The demographic, clinical, pathological characteristics, treatment and follow-up data were analyzed. RESULTS Renal involvement was characterized by nephrotic range proteinuria with microscopic haematuria in all patients, and impaired renal function in nine patients (75%). Purpuric rash was the main extrarenal manifestation (58.3%). Type II cryoglobulinaemia was presented in three patients and type III in nine patients. Hypocomplementaemia and positive of rheumatoid factors were present in all patients. Membranoproliferative glomerulonephritis (MPGN) was observed in all kidney specimens. Seven patients also had evidence of prominent cryoglobulins thrombi on renal biopsy, but only three patients had HBV antigen deposits in renal tissues. Antiviral and steroids or immunosuppressive agents have been used in most of patients. During follow-up, two patients died, and four reaching end-stage renal disease; three patients had complete remission, and three patients had renal function improved after therapy. CONCLUSIONS Nephrotic syndrome with haematuria and renal insufficiency are the main clinical manifestation; cryoglobulinaemic glomerulonephritis are the main renal lesion in patients with HBV-Associated cryoglobulinaemia; half of patients have poor outcome even with antiviral and immunosuppressive therapy. The results of this study indicate that cryoglobulins should be detected in hepatitis B virus-Associated nephropathy in endemic area.

Abstract
Amino acids and energy deficiency lead to lower milk protein content in dairy cows. However, the known mechanisms involved in this process do not adequately explain the variability of milk protein concentration in the mammary gland. We hypothesized that a deficiency in d-glucose (d-Glc) or AA would inhibit casein synthesis by regulating signaling pathways in mammary epithelial cells. Cow mammary epithelial cells (CMEC) were subjected to combinations of 1 of 3 concentrations of d-Glc (0, 2.50, or 17.5 mM) and 1 of 3 concentrations of AA (0, 1.03, or 7.20 mM). The effect of each mixture on cell cycle stage was assessed by flow cytometry. The expression levels of β-casein and κ-casein (encoded by CSN2 and CSN3) were measured by quantitative real-time PCR and Western blotting. Phosphorylation of Janus kinase 2 (Jak2), signal transducer and activator of transcription 5a (Stat5a), AMP-activated protein kinase (AMPK), mammalian target of rapamycin (mTOR), ribosomal protein S6 kinase 1 (S6K1), and eukaryotic factor 4E-binding protein 1 (4EBP1) were analyzed by Western blotting. The percentages of cells in the DNA postsynthetic (G2) and DNA synthesis (S) phases would decrease, with the level of d-Glc or AA declining individually, but no interaction was observed between the d-Glc and AA effects. The CSN2 and CSN3 mRNA and protein were downregulated when d-Glc or AA decreased individually from 17.5 to 2.50 mM or from 7.20 to 1.03 mM, but d-Glc deficiency had a greater effect according to the regression analysis. The phosphorylation ratio of Jak2 (Tyr1007/1008), Stat5a (Tyr694), mTOR (Ser2448), S6K1 (Thr389), and 4EBP1 (Thr37) was downregulated with the level of d-Glc or AA decline, whereas the phosphorylation ratio of AMPK (Thr183/172) was upregulated. And the change of d-Glc level had a more marked effect than AA in regulating the activity of these signaling protein above according to the regression analysis. Thus, d-Glc or AA deficiency likely reduced casein transcription via inhibition of the Jak2/Stat5 pathway, and reduced translation via suppression of the mTOR pathway by activation of AMPK, but d-Glc deficiency had a more marked effect. These indicated that deficiency of AA, and especially Glc, suppressed proliferation of CMEC and casein gene and protein expression, associated with inhibition of JAK2/STAT5 and AMPK/mTOR signaling pathways.

Abstract
OBJECTIVES To explore the occurrence and the differences of clinical manifestations of organic personality disorder with varying degrees of craniocerebral trauma. METHODS According to the International Classification of Diseases-10, 396 subjects with craniocerebral trauma caused by traffic accidents were diagnosed, and the degrees of craniocerebral trauma were graded. The personality characteristics of all patients were evaluated using the simplified Neuroticism Extraversion Openness Five-Factor Inventory (NEO-FFI). RESULTS The occurrence rate of organic personality disorder was 34.6% while it was 34.9% and 49.5% in the patients with moderate and severe craniocerebral trauma, respectively, which significantly higher than that in the patients (18.7%) of mild craniocerebral trauma (P<0.05). Compared with the patients without personality disorder, the neuroticism, extraversion and agreeableness scores all showed significantly differences (P<0.05) in the patients of mild craniocerebral trauma with personality disorder; the neuroticism, extraversion, agreeableness and conscientiousness scores showed significantly differences ( P>0.05) in the patients of moderate and severe craniocerebral trauma with personality disorder. The agreeableness and conscientiousness scores in the patients of moderate and severe craniocerebral trauma with personality disorder were significantly lower than that of mild craniocerebral trauma, and the patients of severe craniocerebral trauma had a lower score in extraversion than in the patients of mild craniocerebral trauma. CONCLUSIONS The severity of craniocerebral trauma is closely related to the incidence of organic personality disorder, and it also affects the clinical features of the latter, which provides a certain significance and help for forensic psychiatric assessment.

Abstract
Alport syndrome (AS) is a clinically and genetically heterogeneous, progressive nephropathy caused by mutations in COL4A3, COL4A4, and COL4A5, which encode type IV collagen. The large sizes of these genes and the absence of mutation hot spots have complicated mutational analysis by routine polymerase chain reaction (PCR)-based approaches. Here, in order to design a rapid and effective method for the genetic diagnosis of AS, we developed a strategy by utilizing targeted capture associated with next-generation sequencing (NGS) to analyze COL4A3, COL4A4, and COL4A5 simultaneously in 20 AS patients. All the coding exons and flanking sequences of COL4A3, COL4A4, and COL4A5 from the probands were captured followed by HiSeq 2500 sequencing. Candidate mutations were validated by classic Sanger sequencing and quantitative (q)PCR. Sixteen patients (16/20, 75%) showed X-linked inheritance, and four patients (4/20, 20%) showed autosomal recessive inheritance. None of the individuals had autosomal-dominant AS. Fifteen novel mutations, 6 known mutations, and 2 novel fragment deletions were detected by targeted capture and NGS. Of these novel mutations, 12, 3, and 2 mutations were detected in COL4A5, COL4A4, and COL4A3, respectively. A comparison of the clinical manifestations caused by different types of mutations in COL4A5 suggested that nonsense mutations and glycine substitution by an acidic amino acid are more severe than the other missense mutations. Pathogenic mutations were detected in 20 patients. These novel mutations can expand the genotypic spectrum of AS. Our results demonstrated that targeted capture and NGS technology are effective in the genetic diagnosis of AS.

Abstract
OBJECTIVE To investigate the correlation of the single nucleotide polymorphism (SNP) rs4880 of the superoxide dismutase 2 (SOD2) gene with the risk of male infertility. METHODS This casecontrol study included 519 male patients with idiopathic infertility (aged 19-40 [28.93±4.93] years) in the case group and 338 fertile men (aged 19-40 [28.40±4.25] years) in the control group. We collected the clinical data, genotyped the SNP rs4880 of the SOD2 gene by Sequenom Mass Array, and analyzed the association of different genotypes with male infertility using the logistic regression model. RESULTS Statically significant differences were observed between the case and control groups in the level of folliclestimulating hormone (FSH) ([4.72±2.51] vs [15.65±17.24] U/L, P< 0.01), the percentage of progressively mobile sperm ([9.12±13.5] vs [41.95±9.03]%, P< 0.01), and sperm concentration ([12.95±24.38] vs [72.88±45.60] ×106/ml, P< 0.01), but not in other parameters. No correlation was found between male infertility and the heterozygous genotype TC (OR = 0.90, 95% CI: 0.65-1.25, P = 0.516) or the homozygous genotype CC (OR=1.49, 95% CI: 0.38-5.81, P = 0.566) as compared with the wild genotype TT, and similar results were obtained in the analysis of the subgroups. CONCLUSIONS The SNP rs4880 of the SOD2 gene was not correlated with male infertility, which, however, is to be supported by further studies with larger samples from more areas.

Abstract
Background The association between psoriasis and membranous nephropathy (MN) remains largely unclear. We examined the prevalence of serum PLA2R antibody and characterized the expression of PLA2R and THSD7A in glomeruli in patients with MN and psoriasis. Methods A total of 24 patients with MN without evidence of a secondary cause except psoriasis were enrolled. The clinical and pathological features were retrospectively analyzed. Serum anti-PLA2R antibody was measured using IFA Mosaic. Renal tissue samples stored in the laboratory bio-bank were used for PLA2R staining under immunofluorescence microscopy and THSD7A immunohistochemical analysis. Results Twenty-four patients (21 male and 3 female) with a mean age of 43.6 ± 15.7 years old were enrolled. Serum anti-PLA2R antibody was positive in 7 patients, which was significantly lower than the positivity observed in idiopathic MN (29.2% vs. 81.7%, P < 0.001). Glomerular PLA2R staining was positive in 7 patients with positive serum anti-PLA2R antibody. THSD7A staining was negative in all 24 patients. During the follow-up visits, 13 patients with negative serum PLA2R antibody achieved CR. In contrast, CR was only achieved in 1 patient with positive serum PLA2R antibody, PR was achieved in 2 patients. Conclusions The prevalence of serum anti-PLA2R antibody and glomerular expression of PLA2R was significantly lower in patients with psoriasis and MN than in those with idiopathic MN, and THSD7A staining was negative, suggesting that MN is associated with psoriasis in the majority of patients. However, idiopathic MN might also accompany psoriasis in a minority of psoriatic patients with positive serum anti-PLA2R antibody.

Abstract
BACKGROUND The interaction between activated microglia and T lymphocytes can yield abundant pro-inflammatory cytokines. Our previous study proved that thymus immune tolerance could alleviate the inflammatory response. This study aimed to investigate whether intrathymic injection of myelin basic protein (MBP) in mice could suppress the inflammatory response after co-culture of T lymphocytes and BV-2 microglia cells. METHODS Totally, 72 male C57BL/6 mice were randomly assigned to three groups (n = 24 in each): Group A: intrathymic injection of 100 μl MBP (1 mg/ml); Group B: intrathymic injection of 100 μl phosphate-buffered saline (PBS); and Group C: sham operation group. Every eight mice in each group were sacrificed to obtain the spleen at postoperative days 3, 7, and 14, respectively. T lymphocytes those were extracted and purified from the spleens were then co-cultured with activated BV-2 microglia cells at a proportion of 1:2 in the medium containing MBP for 3 days. After identified the T lymphocytes by CD3, surface antigens of T lymphocytes (CD4, CD8, CD152, and CD154) and BV-2 microglia cells (CD45 and CD54) were detected by flow cytometry. The expressions of pro-inflammatory factors of BV-2 microglia cells (interleukin [IL]-1β, tumor necrosis factor-α [TNF-α], and inducible nitric oxide synthase [iNOS]) were detected by quantitative real-time polymerase chain reaction (PCR). One-way analysis of variance (ANOVA) and the least significant difference test were used for data analysis. RESULTS The levels of CD152 in Group A showed an upward trend from the 3rd to 7th day, with a downward trend from the 7th to 14th day (20.12 ± 0.71%, 30.71 ± 1.14%, 13.50 ± 0.71% at postoperative days 3, 7, and 14, respectively, P < 0.05). The levels of CD154 in Group A showed a downward trend from the 3rd to 7th day, with an upward trend from the 7th to 14th day (10.00 ± 0.23%, 5.28 ± 0.69%, 14.67 ± 2.71% at postoperative days 3, 7, and 14, respectively, P < 0.05). The ratio of CD4+/CD8 + T in Group A showed a downward trend from the 3rd to 7th day, with the minimum at postoperative day 7, then an upward trend from the 7th to 14th day (P < 0.05). Meanwhile, the levels of CD45 and CD54 in Group A were found as the same trend as the ratio of CD4+/CD8 + T (CD45: 83.39 ± 2.56%, 82.74 ± 2.09%, 87.56 ± 2.11%; CD54: 3.80 ± 0.24%, 0.94 ± 0.40%, 3.41 ± 0.33% at postoperative days 3, 7, and 14, respectively, P < 0.05). The expressions of TNF-α, IL-1β, and iNOS in Group A were significantly lower than those in Groups B and C, and the values at postoperative day 7 were the lowest compared with those at postoperative days 3 and 14 (P < 0.05). No significant difference was found between Groups B and C. CONCLUSIONS Intrathymic injection of MBP could suppress the immune reaction that might reduce the secondary immune injury of brain tissue induced by an inflammatory response.

Abstract
Serum phospholipase A2 receptor antibodies (SAbs) and glomerular phospholipase A2 receptor antigen (GAg) deposits have been observed in idiopathic membranous nephropathy (IMN). However, the clinical application of these two biomarkers, particularly GAg deposition, needs to be further evaluated. We measured SAb concentration by ELISA and GAg deposition by immunofluorescence in 572 patients with biopsy-proven IMN. Overall, 68.5% of patients (392 of 572) had detectable SAb (SAb+), and 98.7% of patients who were SAb+ (387 of 392) and 70.6% of patients who were SAb- (127 of 180) had GAg deposition (GAg+). Compared with patients who were SAb-/GAg+, patients who were SAb+/GAg+ exhibited higher levels of proteinuria (P<0.001) and a lower chance of proteinuria remission (P<0.001). In 52 patients who underwent repeat biopsies, patients who did not achieve remission had a higher SAb+ rate on the first biopsy than patients who went into remission (P=0.001). Furthermore, SAb+ levels persisted in patients who did not achieve remission but significantly decreased in patients who achieved remission by the second biopsy. Patients who did not achieve remission also had a higher GAg+ rate on the first biopsy than patients who achieved remission (P<0.01). Sustained GAg+ deposits correlated with disease relapse. In conclusion, combining the measurements of SAb levels and detection of GAg deposition may provide additional information regarding diagnoses, treatment response, and disease relapse in patients with IMN.

Abstract
The mechanism by which glucocorticoids alleviate renal inflammatory disorders remains incompletely understood. Here, we report that the efficacy of glucocorticoids in ameliorating FSGS depends on the capacity to expand myeloid-derived suppressor cells (MDSCs). After glucocorticoid treatment, the frequency of CD11b(+)HLA-DR(-)CD14(-)CD15(+) MDSCs in peripheral blood rapidly increased in patients with glucocorticoid-sensitive FSGS but remained unchanged in patients with glucocorticoid-resistant FSGS. The frequency of CD11b(+)Gr-1(+) MDSCs in mouse peripheral blood, bone marrow, spleen, kidney-draining lymph nodes (KDLNs), and kidney also increased after glucocorticoid treatment. The induced MDSCs from glucocorticoid-treated mice strongly suppressed T cells, dendritic cells, and macrophages but induced regulatory T cells in spleen, KDLNs, and kidney. Moreover, glucocorticoid treatment suppressed doxorubicin-induced T cell proliferation, dendritic cell and macrophage infiltration, and proinflammatory cytokine production, whereas this protective effect was largely abolished by depleting MDSCs using anti-Gr-1 antibody. Finally, the adoptive transfer of induced MDSCs into the doxorubicin-treated mice not only confirmed the protective role of MDSCs in doxorubicin-induced renal injury but also showed that the transferred MDSCs rapidly migrated into the lymphocyte-accumulating organs, such as the spleen and KDLNs, where they suppressed T cell proliferation. Taken together, these results demonstrate that glucocorticoid treatment ameliorates FSGS by expanding functional MDSCs and that this rapid elevation of MDSCs in peripheral blood may serve as an indicator for predicting the efficacy of glucocorticoid treatment.

Abstract
The aim of this study was to determine the effect of IL-23 on the activity and proliferation of osteoclasts (OC) in co-culture with osteoblasts (OB). OB and OC were individually separated from the skull and femoral bone of a SD rat. OB-OC co-culture with IL-23 added was designed as the experimental group, while the OB-OC co-culture without IL-23 was the control group. In the experimental group, five different concentrations of IL-23 were added, and the cells were then cultured for 24, 48 and 72 h. For each concentration at these three time points, cell proliferation, tartrate-resistant acid phosphatase (TRAP) activity and the lacunae in the bone slices were evaluated, compared with control group at the same time points. Compared to the control group, proliferation and TRAP activity of OC were significantly increased at 24, 48 and 72 h with addition of 0.5 to 10 ng/mL IL-23 (P<0.05). In addition, a dose- and time-dependent correlation between the effect of IL-23 and osteoclastogenesis was noticed though the comparison. Moreover, the area of lacunar resorption in each experimental group was significantly larger than in the control group (P<0.05). In conclusion, IL-23 promotes the proliferation, TRAP activity and bone resorption of OC in OB-OC co-culture.

Abstract
We fabricated and tested periodic metal (Ag)-dielectric (SiO2 or TiO2) multilayers with transparency bands in the visible range. For samples with Ag-TiO2 interfaces, the optical properties exhibited relatively poor predictability, likely due to oxidation of the Ag layers. Ag/SiO2-based multilayers were found to be more predictable and stable, but the relatively low refractive index of SiO2 limits their inherent transparency and pass-band bandwidth. We show that termination of the multilayer with a single high-index layer reduces the admittance mismatch with the ambient media, and thus improves the properties of the transparency band.

Abstract
The auto-test equipment for relative spectral response of charge coupled devices (CCD) was designed and realized. The equipment covered the range of 400 to 950 nm. Firstly, testing theory of relative spectral response for detectors was introduced. Secondly, taking the high sensitive and broad spectral scientific spectrometer-QE65000 as reference, auto-test equipment for relative spectral response was built up by direct comparison method in the same radiation field. Uncertainty analysis showed that the maximum uncertainty of the equipment was less than 6.21%. This auto-test equipment can be used in the CCD assessment and its photoelectrical parameters testing.

Abstract
In order to realize the irradiance calibration of SBUV-ICCD (solar blind ultraviolent Intensified change-coupled device) with dynamic range reaching 120 dB, a light source with long dynamic range was designed and realized. Firstly, the irradiance dynamic range was estimated. Then using deuterium lamp, integrating sphere, precise stop and rail, an ultraviolent light source was developed, which has fixed structure of spectrum, but the irradiance can change continuously in long range. At last the light source's performance was tested. The result shows that the irradiance between 0.278 and 2.8 x 10(-7) microW x cm(-2) was covered, and the stability was 0.93%/3 h. So the demand of calibration of irradiance was satisfied. It will help for measuring the surface uniformity of detector and the calibration of imaging systems.

Abstract
The current study was performed to investigate the effect of aminoguanidine (AG) on spinal cord injury (SCI) in rat. AG (75, 150 and 300mg/kg, i.p. respectively ) was administered to rats immediately following SCI. It was found that AG (150mg/kg) significantly reduced spinal cord water content and improved motor function, however, AG at the doses of 75 and 300mg/kg had no effect. Compared to SCI group without treatment, AG at the dosage of 150mg/kg induced a reduction in the permeability of blood-spinal cord barrier (BSCB) after injury 48h (from 59.8+/-5.5microl/g to 39.8+/-3.8microl/g), a 38% decrease of Malondialdehyde (MDA) values and a 1-fold increase of the Glutathione (GSH) levels at 12h after SCI. And the expression of inducible nitric oxide synthase (iNOS) protein reached a peak at 24h after injury, which was significantly attenuated by treatment with AG (150mg/kg). In addition, the expression of AQP4 protein was down-regulated by the treatment of AG (150mg/kg) at 24h after SCI, and the changes still lasted at 48h after injury. Our results indicated that AG could induce spinal cord edema clearance and improve motor function, which could be correlated with antioxidative property, the down-regulation of iNOS and AQP4 protein expression after SCI.

Abstract
MRL/Mp mice bearing the Fas deletion mutant gene, lpr (MRL/lpr), spontaneously develop polyarthritis, sialoadenitis and dacryoadenitis, resembling rheumatoid arthritis (RA), and also corneal involvement such as keratopathy and scleritis, which is a major complication in RA patients. In this study, we found that the expression levels of IL-1beta and MMP-1 mRNAs in cornea were high in both MRL/lpr and MRL/Mp-+/+ strains of mice at an age younger than when they develop any inflammatory lesions. This was not true of other inbred strains, even those bearing the lpr gene, and also not of (NZB x NZW) F1 lupus mice. There was no significant difference in the expression of IL-1alpha and TGFbeta in cornea in these strains. Using crosses between MRL/lpr and C3H/HeJ-lpr/lpr (C3H/lpr) mice, at least the expression of IL-1beta was found to be under the control of the MRL genetic background, likely with a recessive mode of inheritance. Considering that IL-1beta in cornea was detected particularly in the epithelial layer, the high expression of IL-1beta in cornea is most likely involved in the genetic predisposition for corneal involvement and possibly also for arthritis in an MRL strain of mice.

Abstract
OBJECTIVE To study variations of genome late region of human papillomavirus type 6 (HPV-6) isolated from Chinese patients with condyloma acuminatum. METHODS Using overlap PCR design, major capsid protein (L1) and minor capsid protein (L2) genes were separately amplified from clinical samples following HPV type determination, and were further assembled into HPV-6 genome late region sequences after inserting into plasmid and sequencing. RESULTS Two sequences (GenBank accession number AY015006, AY015008) of HPV-6 late region were assembled, which are 2,869 bp long covering 35% HPV-6 genome and with complete open reading frames (ORFs) for L1 and L2. Compared with prototype sequence, nine point mutations were found, including four missense mutations, three of which were located in L2 ORF. Phylogenetic analysis indicated that the cloned sequences are classified into HPV-6b. CONCLUSIONS HPV-6 genome late region, especially in L1 ORF, is very conserved (variation rate < 0.28%). The mutation from A to G at position 7081 in HPV-6 genome and from G to A at 7099 may represent region characteristics. This is the first report that describes sequence variations among genome late region of HPV-6 isolated from Chinese patients.

Abstract
We showed previously that human malignant non-Hodgkin's lymphomas (NHL) degrade extracellular matrix (ECM) components through the action of metalloproteinases and that elevated expression of matrix metalloproteinase-9 (MMP-9) and tissue inhibitor of metalloproteinase-1 (TIMP-1) correlated with a poor clinical outcome in patients with NHL. In the present study we sought to investigate whether there is any correlation between the expression of gelatinases (MMP-2 and MMP-9), TIMP-1, and the expression of cytokines and growth factors such as interleukin-1beta (IL-1beta), IL-6, IL-10, tumor necrosis factor alpha (TNF-alpha), transforming growth factor beta (TGFbeta), and basic fibroblast growth factor (bFGF) in human NHL. In lymphoma tissues obtained from 32 patients, elevated expression of IL-6 correlated significantly with elevated messenger RNA (mRNA) levels of MMP-9, MMP-2, and TIMP-1. Moreover, in human lymphoid cell lines of B- and T-cell origin (Raji, Jurkat, and NC-37), IL-6 stimulated production of MMP-9 and MMP-2 but not TIMP-1. In the Matrigel invasion assay IL-6 significantly upregulated transmigration of Raji and Jurkat cells, which in turn was inhibited by recombinant human TIMP-1 and anti-MMP-9 and MMP-2 antibodies. We postulate that IL-6 may play a role in the clinical aggressiveness of human NHL by stimulating MMP production.

Abstract
We compared the expression of matrix metalloproteinases (MMP-2 and MMP-9) and tissue inhibitors of metalloproteinases (TIMP-1 and TIMP-2) in bone marrow acute myelogenous leukaemia (AML) blasts and leukaemic cell lines (HEL, HL-60, K-562 and KG-1) with their expression in normal bone marrow cells. All AML samples and leukaemic cell lines tested expressed MMP-9 and/or MMP-2 mRNA and, accordingly, these gelatinases were secreted into media. Moreover, TIMP-1 and TIMP-2 mRNA and secreted proteins were demonstrated in all the AML samples. Although all the leukaemic cell lines expressed TIMP-1, the HL-60 cells also expressed TIMP-2. In contrast, normal steady-state bone marrow immature progenitor cells (CD34+ cells) did not express or secrete either MMP-2 or MMP-9, but more mature mononuclear cells from normal bone marrow expressed and secreted MMP-9. Also, normal bone marrow CD34+ cells and mononuclear cells expressed TIMP-1 and TIMP-2 mRNA, but these proteins were not detectable by reverse zymography. Furthermore, whereas bone marrow fibroblasts and endothelial cells secreted only latent MMP-2, the activated form of this enzyme was found in media conditioned by cells obtained from long-term cultures of normal and AML bone marrow adherent layers. Our finding of up-regulated production of gelatinases, TIMP-1 and TIMP-2 by leukaemic cells suggests that these proteins may be implicated in the invasive phenotype of AML.

Abstract
Congenital cutis laxa, a rare syndrome with marked skin laxity and pulmonary and cardiovascular compromise, is due to defective elastic fiber formation. In several cases, skin fibroblast tropoelastin production is markedly reduced yet reversed in vitro by transforming growth factor-beta treatment. We previously showed that this reversal was due to elastin mRNA stabilization in one cell strain, and here this behavior was confirmed in skin fibroblasts from two generations of a second family. cDNA sequencing and heteroduplex analysis of elastin gene transcripts from three fibroblast strains in two kindreds now identify two frameshift mutations (2012DeltaG and 2039DeltaC) in elastin gene exon 30, thus leading to missense C termini. No other mutations were present in the ELN cDNA sequences of all three affected individuals. Transcripts from both alleles in each kindred were unstable and responsive to transforming growth factor-beta. Exons 22, 23, 26A, and 32 were always absent. Since exon 30 underwent alternative splicing in fibroblasts, we speculate that a differential splicing pattern could conceivably lead to phenotypic rescue. These two dominant-acting, apparently de novo mutations in the elastin gene appear to be responsible for qualitative and quantitative defects in elastin, resulting in the cutis laxa phenotype.

Abstract
Skin fibroblasts from two cases of autosomal recessive cutis laxa (CL), having insignificant elastin production and mRNA levels, were challenged with transforming growth factor beta-1 (TGF-beta 1). Elastin production was brought from undetectable values to amounts typical of normal human skin fibroblasts in a dose-dependent fashion. Basic fibroblast growth factor (100 ng/ml) alone or in combination with TGF-beta 1 reduced elastin production and mRNA expression in CL skin fibroblasts more extensively than in normal cells. In situ hybridization showed that these effects were at the transcript level. One of the CL strains was examined in detail. Transcription rates for elastin were similar in normal and CL and unchanged by TGF-beta 1 or TGF-beta 2 (10 ng/ml), while in CL elastin mRNA half-life was increased > 10-fold by TGF-beta 2 and reduced 6-fold after TGF-beta 2 withdrawal, as compared with a control strain. Cycloheximide partially reversed elastin mRNA instability. These data are consistent with a defect in elastin mRNA stability that requires synthesis of labile factors or intact translational machinery, resulting in an extremely low steady state level of mRNA present in this strain of CL. Furthermore, TGF-beta can relieve elastin mRNA instability in at least one CL strain and elastin production defects in both CL strains.

Abstract
In 1985-1987, a field trial of malaria control using deltamethrin impregnated mosquito nets was carried out with 4,450 people in the Buji district, Bao'an County, Guangdong Province, China. The vectors were exophilic Anopheles sinensis (80%) and the endophilic and anthropophilic An. anthropophagus (20%). The first impregnation of the nets was in June 1985 and the second in April 1986. About 87% of the population slept under treated nets. The indoor vector density decreased by 93% and remained at the same level during the second year. During the second year the average monthly malaria incidence was 1.3% for January-June, a decrease of 74.6% as compared with pretreatment data, and 0.85% from July to December, a decrease of 92.7%. In April 1986 and April 1987, the treatment was extended to the whole Buji District, which has a total population of approximately 40,000. The average monthly malaria incidence (April-December 1986 and 1987) was 0.54% and 0.17%, a decrease of 64.7% and 89% respectively as compared with the same period for the previous year.
