Abstract
The objective of this study was to evaluate whether RSV inhibits neutrophil extracellular traps (NETs) that induce joint hyperalgesia in C57BL/6 mice after adjuvant-induced arthritis. A subplantar injection of Freund's complete adjuvant was administered to C57BL/6 mice on day 0 for immunization in the AIA model. Resveratrol (RSV, 25 mg/kg) was administered intraperitoneally once daily starting on day 22 and continuing for two weeks. The effects of mechanical hyperalgesia and edema formation have been assessed in addition to histopathological scoring. Mice were sacrificed on day 35 to determine cytokine levels and PADI4 and COX-2 expression levels. ELISA was used to quantify neutrophil extracellular traps (NETs) along with neutrophil elastase-DNA and myeloperoxidase-DNA complexes in neutrophils. An immunohistochemical stain was performed on knee joints to determine the presence of nuclear factor kappa B p65 (NF-kappaB p65). AIA mice were found to have higher levels of NET in joints and their joint cells demonstrated an increased expression of the PADI4 gene. Treatment with RSV in AIA mice (25 mg/kg, i.p.) significantly (P<0.05) inhibited joint hyperalgesia, resulting in a significant increase in mechanical threshold, a decrease in articular edema, a decrease in the production of inflammatory cytokines, increased COX-2 expression, and a decrease in the immunostaining of NF-kappaB. Furthermore, treatment with RSV significantly reduced the amount of neutrophil elastase (NE)-DNA and MPO-DNA complexes, which were used as indicators of NET formation (P<0.05). This study indicates that RSV reduces NET production and hyperalgesia by reducing inflammation mediated by PADI4 and COX-2. According to these data, NETs contribute to joint pain and resveratrol can be used to treat pain in RA through this pathway.

Abstract
Several cellular processes, including the recovery of misfolded proteins, the folding of polypeptide chains, transit of polypeptides across the membrane, construction and disassembly of protein complexes, and modulation of protein control, are carried out by DnaJ homolog subfamily A member 1 (DNAJA1), which belongs to the DnaJ heat-shock protein family. It is unknown if DNAJA1 regulates the production of milk in bovine mammary epithelium cells (BMECs). Methionine and leucine increased DNAJA1 expression and nuclear location, as seen by us. In contrast to DNAJA1 knockdown, overexpression of DNAJA1 boosted the production of milk proteins and fats as well as mammalian target of rapamycin (mTOR) and sterol regulatory element binding protein-1c (SREBP-1c). As a result of amino acids, mTOR and SREBP-1c gene expression are stimulated, and DNAJA1 is a positive regulator of BMECs' amino acid-induced controlled milk protein and fat production.

Abstract
Tudor staphylococcal nuclease (Tudor-SN) participates in milk synthesis and cell proliferation in response to prolactin (PRL) and plays a regulatory role on mTOR phosphorylation. However, the complicated molecular mechanism of Tudor-SN regulating milk protein synthesis and cell proliferation still remains to be illustrated. In present study, we observed that the proteins level of phosphorylated Tudor-SN and phosphorylated STAT5 were simultaneously enhanced upon PRL treatment in bovine mammary epithelial cells (BMECs). Tudor-SN overexpression and knockdown experiment showed that Tudor-SN positively regulated the synthesis of milk protein, cell proliferation and the phosphorylation of STAT5, which was dependent on Tudor-SN phosphorylation. STAT5 knockdown experiment showed that Tudor-SN stimulated mTOR pathway through regulating STAT5 activation, which was required for PRL to activate the mTOR pathway. Thus, these results demonstrate the primary mechanism of Tudor-SN coordinating with STAT5 to regulate milk protein synthesis and cell proliferation under stimulation of PRL in BMECs, which may provide some new perspectives for increasing milk production.

Abstract
Nuclear ubiquitous casein and cyclin-dependent kinase substrate 1 (NUCKS1) is a highly phosphorylated nuclear protein ubiquitously expressed in vertebrates. NUCKS1 has been reported to be a key chromatin modifier and transcriptional regulator of a number of signaling pathways, but the physiological role and detailed mechanism are still limited. In this study, we assessed the role of NUCKS1 on milk synthesis in and proliferation of mammary epithelial cells from a dairy cow. NUCKS1 was located in the nucleus of mammary epithelial cells, and the expression of NUCKS1 was stimulated by amino acids (Met and Leu) and hormones (estrogen and prolactin). Gene function study approaches detected that NUCKS1 positively regulated milk protein, milk fat, and lactose synthesis, and also increased the cell number, cell viability, and cell cycle progression. NUCKS1 mediated the stimulation of amino acids and hormones on the messenger RNA expression of the mechanistic target of rapamycin (mTOR), SREBP-1c, and Cyclin D1. The expression of NUCKS1 is dramatically higher in mouse mammary tissue of lactating period, compared with that in puberty and dry period. Taken together, these results reveal that NUCKS1 is a new mediator of milk synthesis in and proliferation of mammary epithelial cells via regulating the mTOR signaling pathway.

Abstract
BACKGROUND MicroRNAs have important roles in many biological processes. However, the role of miR-139 in healthy mammary gland remains unclear. The objective of this study was to investigate the effects of miR-139 on lactation in dairy cows. RESULTS Here, we found that miR-139 was down-regulated in mid-lactation dairy cow mammary tissues compared with mid-pregnancy tissues. Then, we prioritized two of potential target genes of miR-139 in cow, growth hormone receptor (GHR) and type I insulin-like growth factor receptor (IGF1R) for further functional studies based on their roles in lactation processes. Dual luciferase reporter assays validated direct binding of miR-139 to the 3'- untranslated region (UTR) of GHR and IGF1R. Moreover, over-expression or silencing of miR-139 affected mRNA levels of GHR and IGF1R in cultured bovine mammary epithelial cells (BMECs). Furthermore, over-expression of miR-139 decreased protein levels of β-casein, proliferation in mammary epithelial cell, and the protein levels of IGF1R and key members of the GHR or IGF1R pathways as well, whereas silencing miR-139 produced the opposite result. Among these signal molecules, signal transducer and activator of transcription-5 (STAT5), protein kinase B (also known as AKT1), mammalian target of rapamycin (mTOR), and p70-S6 Kinase (p70S6K) are involed in β-casein synthesis, and Cyclin D1 is involved in cell proliferation. In addition, silencing GHR decreased protein levels of β-casein, IGF1R, and key members of the IGF1R pathway, whereas co-silencing miR-139 and GHR rescued the expression of GHR and reversed GHR silencing effects. CONCLUSIONS Our results demonstrate that GHR and IGF1R are target genes of miR-139 in dairy cow. MiR-139 suppresses β-casein synthesis and proliferation in BMECs by targeting the GHR and IGF1R signaling pathways.

Abstract
Tudor staphylococcal nuclease (Tudor-SN) is a highly conserved and ubiquitously expressed multifunctional protein, related to multiple and diverse cell type- and species-specific cellular processes. Studies have shown that Tudor-SN is mainly expressed in secretory cells, however knowledge of its role is limited. In our previous work, we found that the protein level of Tudor-SN was upregulated in the nucleus of bovine mammary epithelial cells (BMEC). In this study, we assessed the role of Tudor-SN in milk synthesis and cell proliferation of BMEC. We exploited gene overexpression and silencing methods, and found that Tudor-SN positively regulates milk synthesis and proliferation via Stat5a activation. Both amino acids (methionine) and estrogen triggered NFκB1 to bind to the gene promoters of Tudor-SN and Stat5a, and this enhanced the protein level and nuclear localization of Tudor-SN and p-Stat5a. Taken together, these results suggest the key role of Tudor-SN in the transcriptional regulation of milk synthesis and proliferation of BMEC under the stimulation of amino acids and hormones.

Abstract
Neonatal chronic intermittent hypoxia (CIH) enhances the ventilatory sensitivity to acute hypoxia (acute hypoxic ventilatory response, HVR), whereas sustained hypoxia (SH) can have the opposite effect. Therefore, we investigated whether neonatal rats pre-treated with SH prior to CIH exhibit a modified HVR. Rat pups were exposed to CIH (5% O2/5min, 8h/day) between 6 and 15 days of postnatal age (P6-15) after pre-treatment with either normoxia or SH (11% O2; P1-5). Using whole-body plethysmography, the acute (5min, 10% O2) HVR at P16 (1 day post-CIH) was unchanged following CIH (67.9±6.7% above baseline) and also SH (58.8±10.5%) compared to age-matched normoxic rats (54.7±6.3%). In contrast, the HVR was attenuated (16.5±6.0%) in CIH exposed rats pre-treated with SH. These data suggest that while neonatal SH and CIH alone have little effect on the magnitude of the acute HVR, their combined effects impose a synergistic disturbance to postnatal development of the HVR. These data could provide important insight into the consequences of not maintaining adequate levels of oxygen saturation during the early neonatal period, especially in vulnerable preterm infants susceptible to frequent bouts of hypoxemic events (CIH) that are commonly associated with apnea of prematurity.

Abstract
OBJECTIVE To establish a new method for observing renal allografts microcirculation and microstructure with acoustic densitometry (integrated backscatter, contrast, second harmonics). METHODS 27 patients with renal allografts were investigated by Doppler, IBS, contrast and second harmonics. Renal allografts failed age in 5 patients 20-61 years. Intravenous injection of SHU-508A was given, compared with pre-injection by quantitative assessment of acoustic densitometry (AD) of renal microstructure. RESULTS There was a significant difference in the peak intensity, the area under the curve and the half-time of wash-out between pre-injection and injection contrast agent. The wish-in and wish-out curve was shown in a peak shape. The renal allografts with acute rejection were significantly lower than the control group in AD (P < 0.05). No contrast opacification of renal microstructure was present in 5 failed renal allografts and the wish-in and wish-out curve appeared in a straight line shape. CONCLUSION AD is safe, and efficient in assessing renal allografts microstructure. It more sensitive in detecting allograft complication such as rejection than Doppler.

Abstract
OBJECTIVE To analyze the outcome of twenty-two years of cadaveric kidney transplantation and the predict factors impacting on graft survival. METHODS The data of 1,180 cadaveric kidney graftings in 1,039 patients between October of 1977 and June of 1999 were summarized by calculation of patient and graft survival rates using Kaplan-Meier product limit estimates. 13 factors that may influence on graft survival were analyzed by the log-rank and Cox model. RESULTS The total of 1-, 5-, 10-, 15-, and 20-year patient survival rates were 93.02%, 80.25%, 67.86%, 65.34% and 65.34%, and the corresponding graft survival rates 88.6%, 68.3%, 43.8%, 43.8%, and 32.8%, respectively. Graft half-life was (13.98 +/- 0.96) years. The longest survivor was 22 years after cadaveric kidney transplantation. The quality of life after grafting in 835 alive patients was improved apparently; 95% of them had a normal graft function and 85% returned to work. The result of multivariable analysis using Cox model showed that 8 factors of patient's age, grafting time, pretransplant blood transfusion, cold ischemia time, delayed graft function, time of normal graft function, immunosuppressive regimen, and acute rejection were very important to affect the graft survival. CONCLUSION Cadaveric kidney transplantation is a successful and effective method to rescue the patients with end-stage renal disease.

PURPOSE To investigate the feasibility of Trabeculectomy on outpatients. METHODS Postspectively compared and discussed the surgery effect and complications of trabeculectomy on 38 eyes of 27 outpatients with those on 38 eyes of 30 inpatients. All the surgeries were performed by the same surgeon in the same period. RESULT The IOP of outpatients' group after one week, one month, three months or more are respectively 1.4800 +/- 0.5977 kPa, 1.8379 +/- 0.5517 kPa, 1.9650 +/- 0.4879 kPa, while the inpatients' group are 1.3468 +/- 0.5994 kPa, 1.7737 +/- 0.5177 kPa, 2.0144 +/- 0.5447 kPa. t-test has shown that the differences of the IOP after the surgery, the surgery effect and complications of trabeculectomy between the outpatients and the inpatients had no significance. CONCLUSION Trabeculectomy on outpatients in hospital with satisfied facility would be effective, safe and feasible.

Abstract
OBJECTIVE To observe the effect of ATG and OKT3 on the treatment of refractory rejection, including acute and chronic rejection after cadaveric kidney transplantation. METHOD 87 patients with refractory rejection after cadaveric kidney transplantation were treated by using ATG (13 patients) and OKT3 (74). A total dose of 1 000 mg for ATG group or 45 mg for OKT3 group was administered for each patient. RESULT Two accelerating rejection and acute rejection were reversed and 7 in the ATG group, 90.00% (27/30) and 90.47% (38/42) in the OKT3 group respectively. A significant difference of total reverse rates was seen between the ATG and OKT3 groups (69.23% verse 90.28%, P < 0.05). In retransplant patients, the reverse rate of acute rejection by OKT3 was 91.67% (11/12). But OKT3 did not show any effect in patients with chronic rejection. CONCLUSION OKT3 is better than ATG for reversing the refractory rejection, especially in retransplant patients, but it has no any effect on chronic rejection.

Abstract
PURPOSE We tried to assess the relationship between quality of life and visual impairment and restoring of patients with cataract and explore the factors which affect quality of life of patients with cataract. METHODS The 142 cases of cataract with different visual impairment and the 33 cases of cataract prior to surgery and at 3 months after cataract extraction and intraocular lens implantation were measured by the scale of quality of life for diseases with visual impairment. RESULTS The scores of quality of life and their subscores were significantly associated with the visual acuity of patients with cataract. The scores of quality of life between preoperation and after surgery had significantly difference. The factors which affect quality of life of patients with cataract included visual impairment, age and occupations. CONCLUSION Visual impairment that caused by cataract would cause decline in quality of life. Cataract surgery was effective in improving visual acuity and quality of life of the patients. Measuring quality of life would afford a new method for evaluating visual impairment of cataract.

Abstract
PURPOSE To describe the development of the of scale quality of life which can measure the quality of life of Chinese patients with visual impairment. METHODS Based on a thorough literature search and consultation with ophthalmologists and public health professionals, 20 items were selected to create a scale. Fifty-seven cataract patients with vision impairment and 60 glaucoma patients with vision impairment and visual field loss were measured by the scale to evaluate the validity, reliability and responsiveness of the scale. RESULTS The scale covered four domains of the quality of life (QOL). The criterion related validity of the scale: r = 0.6865 (P = 0.001). The test-retest reliability of the scale: r = 0.8959 (P = 0.001). Coronback's alpha was 0.9359. The variance ratio (VR) of intra-individual variance to inter-individual variance was 0.0551 for overall scores. The correlation coefficient of split-half method was 0.9553. The responsiveness: T-test, T = 5.95 (P = 0.001), effect size statistic was 1.533. CONCLUSIONS The result demonstrates that the scale has a satisfactory validity, reliability and responsiveness. It suggests that the scale can be applied to clinical trials.

Abstract
A total of 201 consecutive cadaveric kidney transplantations were performed in 188 patients at the Chinese Great Wall Hospital, Beijing, from October 1977 to May 1990. The overall 1-, 2-, 5-, and 10-year graft survival rates were 75.5%, 64.5%, 37.0%, and 32.9%, respectively. In the last 5 years, these figures have risen to 83.7% at 1 year, 69.5% at 2 years, and 40.8% at 5 years, respectively. The 14 variables correlating to graft survival in the present study were analyzed using the log rank test for univariate analysis and the Cox proportional hazard model for multivariate analysis. The results show that immunosuppressive drug therapy, cold ischemia time, acute tubular necrosis, and infection were significant factors affecting the survival of cadaveric kidney grafts. Triple therapy with low-dose cyclosporin, as compared to conventional immunosuppressive drug therapy, significantly increased the 1-year graft survival rate (90.3% vs 31.3%) but did not influence the long-term graft survival rate after 3 years. The incidence of acute tubular necrosis significantly correlated to the cold ischemia time and influenced the 1-year graft survival. Analysis showed that the lymphocytotoxic crossmatch affected graft survival after 3 years and that most late graft losses were due to chronic rejection, suggesting that histocompatibility is the strongest factor affecting long-term graft survival. A beneficial effect of pretransplant blood transfusions on long-term graft survival was seen in patients treated with conventional immunosuppressive drugs but not in cyclosporin-treated patients.
