Abstract
BACKGROUND Immune checkpoint inhibitors in combination with tyrosine kinase inhibitors are standard treatments for advanced clear cell renal cell carcinoma (RCC). This phase III RENOTORCH study compared the efficacy and safety of toripalimab plus axitinib versus sunitinib for the first-line treatment of patients with intermediate-/poor-risk advanced RCC. PATIENTS AND METHODS Patients with intermediate-/poor-risk unresectable or metastatic RCC were randomized in a ratio of 1 : 1 to receive toripalimab (240 mg intravenously once every 3 weeks) plus axitinib (5 mg orally twice daily) or sunitinib [50 mg orally once daily for 4 weeks (6-week cycle) or 2 weeks (3-week cycle)]. The primary endpoint was progression-free survival (PFS) assessed by an independent review committee (IRC). The secondary endpoints were investigator-assessed PFS, overall response rate (ORR), overall survival (OS), and safety. RESULTS A total of 421 patients were randomized to receive toripalimab plus axitinib (n = 210) or sunitinib (n = 211). With a median follow-up of 14.6 months, toripalimab plus axitinib significantly reduced the risk of disease progression or death by 35% compared with sunitinib as assessed by an IRC [hazard ratio (HR) 0.65, 95% confidence interval (CI) 0.49-0.86; P = 0.0028]. The median PFS was 18.0 months in the toripalimab-axitinib group, whereas it was 9.8 months in the sunitinib group. The IRC-assessed ORR was significantly higher in the toripalimab-axitinib group compared with the sunitinib group (56.7% versus 30.8%; P < 0.0001). An OS trend favoring toripalimab plus axitinib was also observed (HR 0.61, 95% CI 0.40-0.92). Treatment-related grade ≥3 adverse events occurred in 61.5% of patients in the toripalimab-axitinib group and 58.6% of patients in the sunitinib group. CONCLUSION In patients with previously untreated intermediate-/poor-risk advanced RCC, toripalimab plus axitinib provided significantly longer PFS and higher ORR than sunitinib and had a manageable safety profile TRIAL REGISTRATION: ClinicalTrials.gov NCT04394975.

Abstract
SCO6993 (606 amino acids) in Streptomyces coelicolor belongs to the large ATP-binding regulators of the LuxR family regulators having one DNA-binding motif. Our previous findings predicted that SCO6993 may suppress the production of pigmented antibiotics, actinorhodin, and undecylprodigiosin, in S. coelicolor, resulting in the characterization of its properties at the molecular level. SCO6993-disruptant, S. coelicolor ΔSCO6993 produced excess pigments in R2YE plates as early as the third day of culture and showed 9.0-fold and 1.8-fold increased production of actinorhodin and undecylprodigiosin in R2YE broth, respectively, compared with that by the wild strain and S. coelicolor ΔSCO6993/SCO6993+. Real-time polymerase chain reaction analysis showed that the transcription of actA and actII-ORF4 in the actinorhodin biosynthetic gene cluster and that of redD and redQ in the undecylprodigiosin biosynthetic gene cluster were significantly increased by SCO6993-disruptant. Electrophoretic mobility shift assay and DNase footprinting analysis confirmed that SCO6993 protein could bind only to the promoters of pathway-specific transcriptional activator genes, actII-ORF4 and redD, and a specific palindromic sequence is essential for SCO6993 binding. Moreover, SCO6993 bound to two palindromic sequences on its promoter region. These results indicate that SCO6993 suppresses the expression of other biosynthetic genes in the cluster by repressing the transcription of actII-ORF4 and redD and consequently negatively regulating antibiotic production.

Abstract
Objective: To investigate the effect of anti-vascular endothelial growth factor (VEGF) therapy on the expression levels of transforming growth factor-beta (TGF-β) and its related microRNAs in the vitreous of patients with proliferative diabetic retinopathy (PDR). Methods: This cross-sectional study included 67 patients (67 eyes), 38 males and 29 females, aged (54.37±11.70) years, who underwent vitrectomy from June 2020 to February 2021. There were 45 PDR patients (45 eyes), including 29 patients (29 eyes) without anti-VEGF therapy in the disease group and 16 patients (16 eyes) who were admitted at 7 days after anti-VEGF therapy in the treatment group. The other 22 idiopathic macular hole patients (22 eyes) were in the negative control group. The microRNA (hsa-miR-24-3p and hsa-miR-197-3p) levels in the vitreous of 36 patients (12 cases randomly chosen from each group) were detected by quantitative reverse transcription polymerase chain reaction. The levels of TGF-β and VEGF-A in the vitreous of 67 patients were detected by enzyme-linked immunosorbent assay. Target gene prediction of hsa-miR-24-3p and hsa-miR-197-3p was performed on RNAhybrid, miRanda and TargetScan7.2 databases, and pathway enrichment analyses were conducted for all target mRNAs. One-way ANOVA was used to compare the levels of growth factors and microRNAs among the three groups, and the least significant difference method was used for multiple comparisons between groups. Pearson correlation test was used to analyze the correlation between growth factors and microRNAs. Results: The expression levels of VEGF-A, TGF-β, hsa-miR-24-3p and hsa-miR-197-3p were (158.15±17.72) pg/ml, (640.47±24.80) pg/ml, 0.81±0.11 and 1.07±0.15 in the control group, (1 047.54±26.61) pg/ml, (3 553.17±92.61) pg/ml, 8.50±2.33 and 12.23±3.38 in the disease group, and (778.10±27.73) pg/ml, (3 376.02±78.83) pg/ml, 4.54±0.67 and 3.90±0.65 in the treatment group, respectively. All indicators were significantly higher in the disease group than those in the control group (F=355.581, 440.538, 7.546 and 7.546; all P<0.05). The expression levels of VEGF-A, hsa-miR-24-3p and hsa-miR-197-3p in the treatment group were significantly lower than those in the disease group (all P<0.05). The concentration of TGF-β was not statistically significantly lower in the treatment group compared to the disease group. The concentrations of VEGF-A and TGF-β were significantly positively correlated with the expression levels of hsa-miR-24-3p and hsa-miR-197-3p in the vitreous of randomly chosen 36 patients (r=0.48, 0.51, 0.40 and 0.42; all P<0.05). Pathway enrichment analysis showed that some target mRNAs of hsa-miR-24-3p and hsa-miR-197-3p were involved in VEGF and TGF-β signal pathways. Conclusions: In the vitreous of patients with PDR, hsa-miR-24-3p and hsa-miR-197-3p were positively related to VEGF-A and TGF-β, and may be potential risk factors. Anti-VEGF treatment can significantly reduce the expression level of TGF-β-related microRNAs, namely hsa-miR-24-3p and hsa-miR-197-3p, but cannot effectively reduce the concentration of TGF-β, suggesting that combined anti-TGF treatment may be beneficial for delaying the progression of PDR. Furthermore, it may be a new research direction of PDR to validate the target mRNAs of hsa-miR-24-3p and hsa-miR-197-3p involved in VEGF and TGF-β signal pathways.

Abstract
Streptomyces coelicolor is a filamentous soil bacterium producing several kinds of antibiotics. S. coelicolor abs8752 is an abs (antibiotic synthesis deficient)-type mutation at the absR locus; it is characterized by an incapacity to produce any of the four antibiotics synthesized by its parental strain J1501. A chromosomal DNA fragment from S. coelicolor J1501, capable of complementing the abs- phenotype of the abs8752 mutant, was cloned and analyzed. DNA sequencing revealed that two complete ORFs (SCO6992 and SCO6993) were present in opposite directions in the clone. Introduction of SCO6992 in the mutant strain resulted in a remarkable increase in the production of two pigmented antibiotics, actinorhodin and undecylprodigiosin, in S. coelicolor J1501 and abs8752. However, introduction of SCO6993 did not show any significant difference compared to the control, suggesting that SCO6992 is primarily involved in stimulating the biosynthesis of antibiotics in S. coelicolor. In silico analysis of SCO6992 (359 aa, 39.5 kDa) revealed that sequences homologous to SCO6992 were all annotated as hypothetical proteins. Although a metalloprotease domain with a conserved metal-binding motif was found in SCO6992, the recombinant rSCO6992 did not show any protease activity. Instead, it showed very strong β-glucuronidase activity in an API ZYM assay and toward two artificial substrates, p-nitrophenyl-β-D-glucuronide and AS-BI-β-D-glucuronide. The binding between rSCO6992 and Zn2+ was confirmed by circular dichroism spectroscopy. We report for the first time that SCO6992 is a novel protein with β-glucuronidase activity, that has a distinct primary structure and physiological role from those of previously reported β-glucuronidases.

Abstract
Objective: To understand the infection status of HCV and Treponema pallidum (TP) in HIV/AIDS cases in Yunnan province,and identify the risk factors. Methods: Between January 1 and June 30 in 2020,a cross-sectional survey was conducted in Yunnan. Two enzyme-linked immunosorbent assay (ELISA) kits were used to detect anti-HCV, the positive results of both two kits indicated HCV infection. ELISA and syphilis toluidine red untreated serum test were applied to identify TP infection. Both Excel 2016 and SPSS 22.0 software were used for statistical analysis, and logistic regression model was conducted to identify the relevant factors of HCV and TP infection. Results: A total of 5 922 HIV/AIDS cases were included in this study, the infection rates of HCV and TP were 6.5% (383/5 922) and 5.8% (344/5 922) respectively. The co-infection rate of HCV and TP was 0.4% (22/5 922). The risk for HCV infection in HIV/AIDS cases was higher in younger age groups compared with age group ≥50 years (15-19:aOR=3.53;20-29:aOR=3.02;30-39:aOR=2.91;40-49:aOR=3.61), in males than in females (aOR=2.31), in the married and unmarried than in the divorced or widowed (married:aOR=1.61;unmarried:aOR=1.63), in other ethnic groups than in Han ethnic group (aOR=1.70), in people with lower education level than in people with education level of college and above (primary school degree and below:aOR=4.69;middle school:aOR=3.96), in people living in the central and western Yunnan than in people living in eastern Yunnan (central Yunnan:aOR=2.46; western Yunnan:aOR=7.08), in injection drug users than in MSM (aOR=131.08). The risk of TP infection in HIV/AIDS cases was higher in people with education level of college and primary school than in middle school degree (primary school and below:aOR=1.73;college and above:aOR=1.77), in people with other occupations than in farmers (aOR=1.39), in people living in eastern Yunnan than in people living in western Yunnan (aOR=1.75); in MSM than in people with heterosex (aOR=9.75). Conclusions: A certain proportion of HIV/AIDS cases reported between January and June in 2020 in Yunnan were co-infected with HCV and TP, many factors were associated with the co-infection. It is suggested to strengthen HCV and TP tests in HIV/AIDS cases and conduct active treatment of the co-infection.

Abstract
BACKGROUND Primary chondrosarcoma of the liver are extremely rare. Moreover, there are few reports focusing on typical clinical symptoms and imaging characteristics. Therefore, the diagnosis of chondrosarcoma of the liver remains a challenge.
CASE SUMMARY A 59-year-old male was admitted due to a lesion occupying the right liver lobe that was found by physical examination. Magnetic resonance imaging showed a lobular mass with high T2 weighted image and low T1 weighted image with enhanced internal separation and edge in the right liver. He was diagnosed with liver cystadenoma by using magnetic resonance imaging. At 3 mo later, the magnetic resonance scan showed that the mass was enlarged. Laparoscopic liver tumor resection was performed with a pathological diagnosis of liver chondrosarcoma. Then he received a surgical resection for the recurrent lesion. However, intrahepatic and abdominal metastases were found again at 8 mo after the second operation. The patient then received conservative management and is now under follow-up.
CONCLUSION Primary liver chondrosarcoma generally is presented as lobulated and heterogeneous density/signal, cystic, solid masses without calcification with enhanced edge, internal septa and solid part. The imaging features are closely related to pathology, which may be helpful for clinical diagnosis.

Abstract
Objective: To understand the characteristics of HIV-1 genotypes and drug resistance among men who have sex with men in Kunming in 2018. Methods: A total of 193 plasma samples were collected from the newly reported HIV-1 infected MSM in Kunming from January to December 2018. Viral RNA was extracted, and the gag, pol, env gene segments were amplified by nested PCR. HIV-1 genotypes and drug resistance were also analyzed. Subsequently, the evolutionary characteristics of CRF55_01B and CRF68_01B among MSM in Kunming were analyzed by Bayesian Markov Chain Monte Carlo method. Results: Multiple HIV-1 genotypes were identified among these 193 samples, including CRF07_BC (39.4%, 76/193), CRF01_AE (34.2%, 66/193), unique recombinant forms (URFs) (20.2%, 39/193), CRF08_BC (3.1%, 6/193), CRF55_01B (1.6%, 3/193), subtype B (1.0%, 2/193) and CRF68_01B (0.5%, 1/193). Results from the Bayesian evolutionary analysis showed that CRF55_01B started to spread locally after being imported from other provinces, while CRF68_01B was likely to have been brought in from the eastern provinces of China. Prevalence of HIV-1 drug resistant strains was 2.6%(5/190) before antiviral treatment, with mutation rates resistant to non-nucleoside reverse transcriptase inhibitors being the highest (2.1%, 4/190) among MSM in Kunming, 2018. Conclusion: The diversity of HIV-1 was increasing among MSM in Kunming. Although the resistance rate on pretreatment drug was relatively low, the emergence of multiple resistant strains to first-line antiviral drugs posed a challenge to antiretroviral therapy, in Kunming.

Abstract
Objective: To analyze the characteristics of HIV-1 molecular network in men who have sex with men (MSM) from 2016 to 2018 in Kunming, Yunnan province, explore the risk factors associated with HIV-1 transmission network and provide evidence for the effective implementation of intervention. Methods: A total of 540 samples of newly reported HIV-1 positive MSM were consecutively collected in Kunming from 2016 to 2018, the pol gene fragments were amplified by nested polymerase chain reaction (PCR). HIV-1 molecular networks were constructed according to the bootstrap value of the maximum likelihood evolutionary tree over 95% and the genetic distance less than 3%. The factors associated with the subjects entering network and network growth were further analyzed. Results: Among 459 successfully sequenced samples, seven genotypes were found, in which CRF07_BC (49.2%, 226/459) and CRF01_AE (40.3%, 185/459 ) were predominant. Other genotypes included URFs (4.8%, 22/459), CRF08_BC (3.1%, 14/459), CRF55_01B (1.7%, 8/459), B (0.7%, 3/459) and CRF68_01B (0.2%, 1/459). A total of 163 sequences entered the network, with an entry rate of 35.5%(163/459), forming 56 clusters with the number of individuals in the cluster was between 2 and 13. The analysis of the factors associated with entering network showed that the MSM who married and had multiple homosexual partners were more likely to be found in HIV-1 molecular networks. Multivariate logistic regression analysis showed that the number of sexual partners was the factor for the growth of HIV-1 molecular network. According to the criteria for the emergence of three or more newly reported cases in every year, six transmission clusters were judged as active transmission clusters, in which MSM who were not Kunming natives, had sexually transmitted diseases (STD), were divorced and students were the key targets of intervention. Conclusions: HIV-1 genotypes in MSM in Kunming were becoming complex, the risk factors associated with transmission networks in MSM in Kunming included being married and having multiple partners, the intervention targets in active transmission clusters included MSM who were not Kunming natives, had STD, were divorced and students. This study provided the basis for applying HIV-1 molecular networks to real-time intervention in this population.

Abstract
In two growing seasons of wheat (2015-2017), we conducted a field trial with Taishan 28 in Tai'an Academy of Agricultural Science Feicheng experimental base, Tai'an City, Shandong Province. There were four irrigation levels of 150 (A1), 300 (A2), 450 (A3), and 600 (A4) m3·hm-2, and four nitrogen application levels of 90 (B1), 135 (B2), 180 (B3), and 225 (B4) kg·hm-2. We examined the effects of the combination effects of irrigation and nitrogen on dry matter accumulation and transport, nitrogen accumulation and transport, water consumption and utilization, photosynthetic characteristics, wheat grain yield and yield components of wheat. The results showed that dry matter accumulation, nitrogen accumulation, vegetative organs production, storage and the transportation volume to grains of the dry matter and nitrogen, and dry matter and nitrogen accumulation of grain in the mature stage of wheat all reached the maximum in A3B3 treatment, which were significantly different from other treatments. Under all the nitrogen treatments, soil water consumption in the 60-200 cm soil layer was A3>A4>A2>A1. Water use efficiency and nitrogen use efficiency in A3B3 treatment were higher than that under A3B4, A4B3 and A4B4. The net photosynthetic rate, stomatal conductance and transpiration rate of flag leaves from 7 to 28 days after flowe-ring were all significantly higher in A3B3 treatment, which was conducive to the photosynthetic synthesis of carbohydrates in wheat. The interaction effect of water and nitrogen addition significantly affected grain yield and yield components. Wheat yield was the highest in A3B3 treatment which reached at 9400 kg·hm-2. In conclusion, the treatment with irrigation of 450 m3·hm-2 and nitrogen of 180 kg·hm-2 could significantly improve dry matter and nitrogen accumulation, and promote transportation volume of the dry matter and nitrogen to grain. Compared with the high water and nitrogen treatment, it could effectively increase water use efficiency and nitrogen use efficiency, enhance photosynthetic capacity of flag leaf, produce more carbohydrate, and increase grain yield.

Abstract
Most of the biosynthetic pathways for secondary metabolites are influenced by carbon metabolism and supply of cytosolic NADPH. We engineered carbon distribution to the pentose phosphate pathway (PPP) and redesigned the host to produce high levels of NADPH and primary intermediates from the PPP. The main enzymes producing NADPH in the PPP, glucose 6-phosphate dehydrogenase (encoded by zwf1 and zwf2) and 6-phosphogluconate dehydrogenase (encoded by zwf3), were overexpressed with opc encoding a positive allosteric effector essential for Zwf activity in various combinations in Streptomyces lividans TK24. Most S. lividans transformants showed better cell growth and higher concentration of cytosolic NADPH than those of the control, and S. lividans TK24/pWHM3-Z23O2 containing zwf2+zwf3+opc2 showed the highest NADPH concentration but poor sporulation in R2YE medium. S. lividans TK24/pWHM3-Z23O2 in minimal medium showed the maximum growth (6.2 mg/ml) at day 4. Thereafter, a gradual decrease of biomass and a sharp increase of cytosolic NADPH and sedoheptulose 7-phosphate between days 2 and 4 and between days 1 and 3, respectively, were observed. Moreover, S. lividans TK24/pWHM3-Z23O2 produced 0.9 times less actinorhodin but 1.8 times more undecylprodigiosin than the control. These results suggested that the increased NADPH concentration and various intermediates from the PPP specifically triggered undecylprodigiosin biosynthesis that required many precursors and NADPH-dependent reduction reaction. This study is the first report on bespoke metabolic engineering of PPP routes especially suitable for producing secondary metabolites that need diverse primary precursors and NADPH, which is useful information for metabolic engineering in Streptomyces.

Abstract
OBJECTIVE To determine the association between incident proton pump inhibitor (PPI) use and Clostridium difficile infections across multiple countries Method: National data covering the total population in Australia and Korea, the Canadian population over 65 years and a 3 million person random sample data set from Taiwan were assessed, as were data from a worker insurance population and a hospital inpatient/outpatient population in Japan. Sequence symmetry analysis was used to assess the association with oral vancomycin dispensing as the outcome of interest. RESULTS 54,957 patients were included. Positive associations were observed in Australia; adjusted sequence ratio (ASR) 2.48 (95% CI 1.90, 3.12), Korea ASR 2.15 (95%CI 2.11, 2.19), Canada ASR 1.45 (95% CI 1.16, 1.79), Japan hospital dataset ASR 3.21 (95%CI 2.12, 4.55) and Japan worker insurance dataset ASR 5.40 (95% CI 2.73, 8.75). The pooled result was ASR 2.40 (95%CI 1.88, 3.05) and 3.16 (95%CI 1.95, 5.10) when limited to Japan, Korean and Taiwan. Results did not vary by individual PPI. The temporal analysis showed effects within the first two weeks of PPI initiation. CONCLUSION Our study confirms the association between PPI initiation and C. difficile infections across countries in the Asia-Pacific region.

Abstract
Retinoblastoma is a commonly seen and dangerous intraocular malignant tumor in infants. Studies have found that Claudin-1 and MMP-2, whose expressions may be connected, play roles in tissues of retinoblastoma. In this study we analyze and discuss changes of Claudin-1 and MMP-2 expressions, and the correlation between the expressions and retinoblastoma histological differentiation and optic nerve invasion. MaxVisionTM was applied to detect expressions of Claudin-1 and MMP-2 in 45 samples of retinoblastoma and 15 paraffin-embedded samples of normal retina. The correlation between Claudin-1 expression and MMP-2 expression was analyzed based on chi-squared test and Spearmans correlation test. Positive expressions of Claudin-1 in retinoblastoma were fewer than those in retina; higher positive expressions were found in differentiated tissues than in undifferentiated tissues; while compared to expressions in invasive optic nerves, Claudin-1 expressed more positively in optic nerves without invasion. As for MMP-2, its expressions were higher in retinoblastoma than in normal retina; undifferentiated tissues had higher positive expressions than differentiated tissues, which were not statistically significant; higher positive expressions were detected in invasive optic nerves. Thus, it could be concluded that the correlation between Claudin-1 expression and MMP-2 expression in retinoblastoma was negative. Expressions of Claudin-1 were positively related to histological differentiation and optic nerve invasion of retinoblastoma; while MMp-2 expression had negative correlation with histological differentiation and optic nerve invasion of retinoblastoma. Claudin-1 and MMP-2 played a negative role in the optic nerve invasion and tumor development of retinoblastoma.

Abstract
This study was conducted to investigate disease-modifying antirheumatic drug (DMARD) utilization in Korean elderly patients with rheumatoid arthritis (RA). We used data from January 1, 2005 to June 30, 2006 from the Health Insurance Review and Assessment Service claims database. The study subjects were defined as patients aged 65 yr or older with at least two claims with a diagnosis of RA. DMARD use was compared by the patients' age-group, gender, medical service, and geographic divisions. The patterns of DMARD use in mono- and combination therapy were calculated. RA medication use was calculated by the number of defined daily doses (DDD)/1,000 patients/day. A total of 166,388 patients were identified during the study period. DMARD use in RA patients was 12.0%. The proportion of DMARD use was higher in the younger elderly, females, and patients treated in big cities. Hydroxychloroquine was the most commonly used DMARD in monotherapy, and most of the combination therapies prescribed it with methotrexate. DMARD use in elderly RA patients was noticeably low, although drug prescriptions showed an increasing trend during the study period, clinicians may need to pay more attention to elderly RA patients.

Abstract
We aimed to determine the characteristic adverse events (AEs) of iodinated contrast media (IOCM) and to compare the safety profiles of different IOCM. This study used the database of AEs reports submitted by healthcare professionals from 15 Regional Pharmacovigilance Centers between June 24, 2009 and December 31, 2010 in Korea. All reports of IOCM, including iopromide, iohexol, iopamidol, iomeprol, ioversol, iobitridol and iodixanol, were analyzed. Safety profiles were compared between different IOCM at the system organ level using the proportional reporting ratio (PRR) and 95% confidence interval (95% CI). Among a total of 48,261 reports, 6,524 (13.5%) reports were related to the use of IOCM. Iopromide (45.5%), iohexol (16.9%), iopamidol (14.3%) and iomeprol (10.3%) were identified as frequently reported media. 'Platelet, bleeding & clotting disorders' (PRR, 29.6; 95%CI, 1.9-472.6) and 'urinary system disorders' (PRR, 22.3; 95% CI, 17.1-29.1) were more frequently reported for iodixanol than the other IOCM. In conclusion, the frequency of AEs by organ class was significantly different between individual media. These differences among different IOCM should be considered when selecting a medium among various IOCM and when monitoring patients during and after its use to ensure optimum usage and patient safety.

Abstract
Plasma gelsolin, the extracellular gelsolin isoform, circulates in the blood of healthy individuals at a concentration of 200 ± 50 mg/l and plays important roles in the extracellular actin-scavenging system during tissue damage. Decreased plasma gelsolin levels have been observed in many inflammatory diseases. In the present study, the variation and potential clinical application of plasma gelsolin levels in patients with systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA) were analysed. Plasma samples and clinical data were collected from informed and consenting participants: 47 SLE patients, 60 RA patients and 50 age- and gender-matched healthy individuals. Semiquantitative western blotting was used for measuring plasma gelsolin levels. The plasma gelsolin levels in patients with SLE and RA were significantly decreased compared with healthy controls (145.3 ± 40.4 versus 182.7 ± 38.3 mg/l and 100.8 ± 36 versus 182.7 ± 38.3 mg/l, p < 0.001), and plasma gelsolin levels were especially lower in RA than in SLE patients (100.8 ± 36 versus 145.3 ± 40.4 mg/L, p < 0.001). An analysis of the clinical data showed a significant negative correlation between plasma gelsolin levels and SLE Disease Activity Index (SLEDAI) scores (r = 0.659, p < 0.001) but no correlation between plasma gelsolin levels and RA disease activity score 28 (DAS28) (r = 0.076, p = 0.569). Different clinical characteristics were also observed in SLE and RA patients with normal and decreased plasma gelsolin levels.This study found significantly lower plasma gelsolin levels in patients with SLE and RA compared with healthy controls and documented a significant negative correlation between plasma gelsolin levels and SLEDAI, which suggested the potential clinical application of plasma gelsolin in SLE diagnosis and disease activity evaluation. The different clinical characteristics in SLE and RA patients with normal and decreased plasma gelsolin levels indicate differences in the basis of the diseases.

Abstract
The knockdown of Bmi-1 could effectively suppress cancer cell proliferation and tumourigenicity in several cancers. This study aims to investigate whether or not Bmi-1 plays a causative role in the proliferation of ovarian epithelial cancer cells and telomerase activity. The messenger RNA (mRNA) and protein expression levels of Bmi-1 in the human ovarian carcinoma cell line OVCAR-3 were downregulated by Bmi-1 siRNA, as confirmed by real-time polymerase chain reaction (PCR) and Western blot. Cell viability was analysed by MTT assay, and telomerase activity was analysed by a modified telomeric repeat amplification protocol. Targeting Bmi-1 with siRNA inhibited Bmi-1 mRNA over five-fold compared with the control cells, and inhibited Bmi-1 protein expression over three-fold compared with control cells. The viability of the OVCAR-3 ovarian cancer cell line was reduced by Bmi-1 mRNA compared to control cells. Telomerase activity was decreased 22.73% (from 0.33 to 0.255) by Bmi-1 siRNA treatment compared to control cells. As Bmi-1 siRNA depressed telomerase activity, cell immortalisation may be prevented; thus, silencing Bmi-1 may be a potential therapy to manage ovarian cancer.

Abstract
Polymerase chain reaction (PCR) products of the MSTN gene amplified from sixty sheep of nine Chinese indigenous sheep breeds and one imported sheep breed were sequenced to identify the single-nucleotide polymorphisms (SNPs) in a 378-bp fragment including intron 2 and exon 3 of the MSTN gene. A total of fifteen SNPs (A1937C, T1942G, C1956T, A1972C, A1990G, A2008C, A2011G, C2019T, A2025C, A2027C, T2085G, T2173C, C2198T, C2210T and C2213T) were detected among the sixty sequenced individuals and they were all located in intron 2. Twelve haplotypes were identified from these fifteen SNPs, of which haplotype I (CGTCGCGTCCGCTTT) and VIII (ATCAAAACAATTCCC) were the two major and basic ones with frequencies of 12.25% and 77.80%, respectively. Haplotype VIII was distributed in all sheep breeds and all individuals of the meat or meat-wool type sheep breeds were homozygous with respect to this haplotype. This suggests that haplotype VIII might be related to meat production traits in sheep. Haplotype I was only distributed in the fur, lambskin type and fur-meat type sheep breeds. This suggests that haplotype I may have some relationship with fur traits in sheep.

Abstract
The epidemic of HIV/AIDS greatly threatens Chinese youth. Our study was intended to examine the effectiveness of the peer education method in HIV/AIDS prevention in different types of senior high schools in Shanghai. A peer education intervention was conducted in 10 different types of senior high schools, including three key senior schools, four ordinary senior schools and three vocational schools in Shanghai for three months. A cohort of 1910 students was surveyed (n=976 intervention group, n=934 control group) through anonymous questionnaires, both pre- and postintervention. There were significant differences in the results among these different types of senior schools. Peer education is an efficient method of increasing the knowledge of AIDS/sexually transmitted diseases in senior school students. However, the contents and the schedule should be different between different types of schools, and students in vocational schools require more health education.

Abstract
The 8-hydroxy-2′-deoxyguanosine (8-OHdG), an oxidized nucleoside of DNA, not only is a widely used biomarker for the measurement of endogenous oxidative DNA damage but might also be a risk factor for many diseases including cancer. Metal exposure may play an important role in oxidative DNA damage among children. However, few studies on urinary 8-OHdG and metals have been conducted in children with acute leukemia. In the present study, urinary Ni and 8-OHdG were examined in 116 children with acute leukaemia (94 acute lymphoid leukaemia [ALL] and 22 acute myeloid leukaemia [AML]) and 51 healthy child controls. Our result showed that urinary Ni in acute leukaemia patients (ALL: 68.40 ± 133.98, AML: 41.48 ± 76.31 ng/mg creatinine) was significantly higher than that in controls (62.47 ± 124.90 vs 17.63 ± 46.17 ng/mg creatinine, P < 0.05). Similarly, the pretherapy level of urinary 8-OHdG in patients (ALL: 11.83 ± 16.23, AML: 12.36 ± 11.36 ng/mg creatinine) was significantly elevated compared with controls (11.92 ± 15.42 vs 4.03 ± 4.70 ng/mg creatinine, P < 0.05). Moreover, urinary 8-OHdG and urinary Ni showed a weak but significant association with increased risk of childhood leukaemia. The present study suggests that Ni may be an etiologic factor for childhood acute leukaemia by oxidative DNA damage.

Abstract
BACKGROUND To explore the relationship between hepatitis B virus (HBV) infection and development of IgA nephropathy. METHODS HBsAg and HBcAg protein in renal biopsy specimens of 32 cases was detected on frozen sections and HBV DNA was detected in paraffin section of renal biopsies and in serum of 42 HBsAg positive cases. RESULTS The positive rate of HBAg in renal biopsies of IgA nephropathy was 59.1%, and 63.6% in non-IgA nephropathy, there was no significant difference between them. In 42 cases biopsies of renal tissues, only five were HBV-DNA positive (11.9%). The five cases were HBsAg, HBcAb and HBeAg positive, the pathological diagnosis of two cases were mesangial proliferative glomerulonephritis; one had minimal change of glomerulonephritis; and one had basement membrane change; and only one had IgA nephropathy. At the same time, in 42 HBsAg+ cases the serum specimens were detected; 12 cases were positive for HBsAg, HBcAg and HBeAg, in whom serum HBV-DNA was positive, but only 5 were positive for HBV-DNA in renal biopsy tissue, and HBV-DNA was negative in other 30 blood serum and tissue specimens. CONCLUSION The difference in expression of HBsAg, HBcAb and HBeAg protein between IgA nephropathy and non-IgA nephropathy tissue from renal biopsy was not significant. There is no direct relationship between HBV infection and IgA nephropathy.

Abstract
OBJECTIVE To explore whether is methylcobalamin effective in prophylaxis of AmAn ototoxic action. METHOD We attempted to use a single injection of gentamicin(125 mg/Kg b.i.w.) to make an animal (guinea pig) model of transient sensory disturbance of hearing, and by a series observation of the changes in ECochG to find out the antagonistic action of methylcobalamin which was simultaneously given to animals(1 mg/Kg, i.m.) followed injection of gentamicin. RESULT 1. The transient ototoxic action of gentamicin may cause delay of latency and diminution of amplitude of CAP N1 and N2 in animals with a single injection of gentamicin. Though the interval between N1 and N2 prolonged, the changes were still within normal ranges. 2. By contrast, the changes of delay at N1 and N2 as mentioned above were significantly improved in animals administered simultaneously with methylcobalamin. CONCLUSION It indicated that in addition to the improvement of physiologic function of nerve fibres, methylcobalamin may be also an agent to prevent the transient ototoxic action of gentamicin. Due to methylcobalamin acts as a methyl donor, it participates the synthesis of SAM (S-adenosylmethionine) and thus products GSH(Glutathion SH), the latter may inhibit ototoxic side-effects of gentamicin.

Abstract
OBJECTIVE To clarify the clinicopathologic features of neuroendocrine carcinomas (NECs) of the stomach, we reviewed 56 cases of surgically treated gastric carcinomas with a solid growth or with areas containing patterns characteristic for neuroendocrine (NE) tumors. METHODS Of the 56 cases reviewed, we selected 33 cases of NEC based both on histologic patterns common to NE tumors and on histochemical/immunohistochemical results. RESULTS The average age of patients with NEC was 69.8 years (range, 44-92 years). The majority of patients were men (male-female ratio, 23:10). The most frequently affected site was the upper third (46%) of the stomach. Grossly, 9 cases of NEC were fungating and 24 were ulcerated. As compared with 23 patients with non-NEC tumors, the patients with NECs had a worse prognosis. Histologically, NECs had a variety of histologic patterns, including solid, organoid, trabecular, pseudoglandular, spindle cell, and rosettelike. Based on both cell size and morphologic features, we subdivided NECs into 2 variants, namely, small cell NEC and large cell NEC. Our series included 12 cases of small cell NEC and 21 cases of large cell NEC. CONCLUSIONS Compared with small cell NECs, large cell NECs had a higher mitotic count, larger polygonal cells, a lower nuclear-cytoplasmic ratio, coarser nuclear chromatin, and more frequent conspicuous nucleoli. Large cell NEC was an aggressive tumor with a very poor prognosis (median survival time, 15.2 months; 1-year survival rate, 58%), which approached that for small cell NEC.

Abstract
We used a prospective study design to assess the effects of prenatal low-level lead exposure on the development of urban, inner-city children in Shanghai. Umbilical cord blood samples wee consecutively collected from 605 live newborns. Two hundred and fifty-seven samples were excluded from the study due to clotting. Lead levels were determined on 348 cord blood samples. The geometric mean was 9.2 micrograms/dl. Based on their cord blood lead levels, infants were classified into two exposure groups: 104 in a relatively low lead group (lead levels < or = 30 percentile), and 104 in a relatively high lead group (lead levels > or = 70 percentile). Seventy-five subjects failed to complete the study, and 133 babies were included in the final cohort: 69 babies in the high lead group and 64 in the low lead group. At 3, 6, and 12 months, the Bayley Scales of Infant Development were administered and capillary blood lead levels were measured. Detailed information was obtained on a wide range of variables relevant to infant development. At all three ages, the Mental Development index (MDI) scores, adjusted for confounders, were inversely related to the infants' cord blood lead levels. The difference of the mean adjusted MDI scores between low and high lead groups was 3.4 at 3 months, 6.3 at 6 months, and 5.2 at 12 months of age. These differences were statistically significant at all time points. No significant association between cord blood lead levels and the Psychomotor Development Index (PDI) scores was detected at all three visits after adjustment for confounders. Postnatal lead levels were unrelated to concurrent developmental status. We conclude that prenatal low-level lead exposure, which is relatively common in Shanghai, is associated with an adverse developmental impact on children through the first year of life.

Abstract
This study was designed to determine the cord blood lead (BPb) levels of babies born in one urban area of Shanghai, and to preliminarily identify the demographic, social environment and prenatal factors which have an effect on the cord BPb concentrations. From August to November 1993, umbilical cord blood samples were obtained from 605 live newborns in the Yangpu Maternal and Child Hospital. 257 samples were excluded from measurement because of clotting. In 348 cord samples, the geometric mean of cord BPb levels was 9.2 micrograms/dl, with a 95% confidence interval of the mean 8.86-9.54 (micrograms/dl). 142 babies (40.8%) had cord BPb levels of 10 micrograms/dl or greater. As a result of this high percentage of newborns with BPb levels equal to or greater than 10 micrograms/dl, we estimate that each year in the Shanghai City about 60,000 newborns are at risk for developing neuropsychological deficiencies caused by maternal lead exposure during pregnancy. To investigate the factors affecting cord blood levels, the subjects with levels greater than the 70th percentile (10.7 micrograms/dl) (n = 104) and less than the 30th percentile (7.4 micrograms/dl) (n = 104) were selected to compare the demographic, environment and prenatal medical history. Increased BPb levels at birth were associated with maternal passive smoking, a family member being occupationally exposed to lead, proximity to major traffic way, household coal combustion, neighborhood coal combustion, low level of maternal occupations, and the increasing occurrence of having the high lead foodstuff pidan (preserved duck egg) during pregnancy. We conclude that prenatal lead exposure has become an important health issue for young children in Shanghai.

Abstract
Microwave is used to treat temporal hearing loss caused by intravenous injection of the ethacrynic acid in guinea pigs. The recovery of hearing is much faster in the treated groups than in the control group. The article proposes possible mechanism of the effects against the ethacrynic acid induced deafness and assume that the result of this research can provide an experimental basis for treatment of some perceptive deafness due to ischemia of stria vascularis of the cochlea.

Abstract
In this paper, we reported a novel monoclonal antibody against human keratins, R 6-2-14. The antigen used for immunization was derived from human callus, keratins in which traditionally are classified as "Soft" keratins. However, when we studied the tissue specificity of this antibody, it was found that it only reacted strongly with "Hard" keratins of various mammalian species, but no detectable cross-reactivity with any of the "Soft" keratins. This antibody may provide a useful tool for the study of hair regeneration, nail regeneration, corn pathology and differentiation of mammalian epidermal derivatives.

Abstract
A reliable animal model of acute type of endolymphatic hydrops was made with injection of artificial endolymph into the cochlear duct. In 12 animals without Reissner's membrane rupture, the endolymphatic potentials (EP) were kept normal after injection of artificial endolymph, but their electrocochleography (ECoG) showed as: a rise of summating potentials (SP) amplitude, a decrease of action potentials (AP) amplitude, an increase of SP/AP ratio, as well as a delay of N1 latency. In 7 animals with membrane rupture, the EP significantly decreased. ECoG showed as: a decrease of hearing function in all test frequencies, a distortion of SP-AP wave and even a loss of AP. Based on the results of our experiment it can be assumed that the dominant -SP may be seen in the acute stage of endolymphatic hydrops without a rupture of Reissner's membrane. Therefore, the dominant -SP may only be of value in the clinical diagnosis during episodic vertigo and fluctuating hearing loss of Meniere's disease.

Abstract
DNA of peripheral blood or bone marrow leukocytes from 8 normal subjects, 7 cases of acute lymphocytic leukemia (ALL), 2 of acute myelogenous leukemia (AML) and 1 of chronic myelogenous leukemia (CML), having been digested by endonuclease Eco RI or Pst I separately, was hybridized with the probes of 3' fragment (Pst I/Hind III) or 5' fragment (Hinc II/Pst I) of Abelson murine leukemia virus (A-MuLV) oncogene v-abl. The proto-oncogene c-abl, which is homologous to v-abl, was found amplified in 4 ALL, 1 CML and 1 AML. In one of these 4 ALL, c-abl was amplified even over 100 times. A new c-abl BamH I fragment with 6.7 kilobase pairs (kb) in length was observed in 2 ALL and 1 CML out of these 6 cases with amplification, but none of this fragment was found in the normal subjects or other leukemia patients. These 3 patients with the presence of 6.7 kb fragment were high risk ones and 2 of them had died, suggesting that 6.7 kb fragment be the index of poor prognosis. The amplification and rearrangement of c-abl imply the activation of proto-oncogene in leukemogenesis.
