Abstract
The importance of real estate development has been widely accepted by all countries. Through early warning and avoidance of real estate financial risks, it can effectively promote the healthy and healthy development of the real estate industry, avoiding the impact of accidental factors, such as the COVID-19 pandemic, and promoting the overall economic development. Based on multiple regression analysis and grey prediction methods, this article constructs a real estate financial risk estimation model, and the real estate financial risk is estimated using the relevant data of Liaoning Province from 2001 to 2020. Analyzing the research results of financial risks in Liaoning Province, we can find that the real estate financial risks reached the peak in 2013, and then the real estate financial risks gradually showed a slow decline trend. In general, the financial risks in Liaoning Province are controllable. The study of financial risks in Liaoning Province will help to judge the development of the real estate industry and promote the continuous improvement of the overall economy. The article, through the study of real estate financial risks in Liaoning Province, can promote the development of regional real estate in Liaoning Province and promote the overall economic development of Liaoning Province, which has strong practical significance. The study of real estate financial risks, relevant risk research theories can be enriched, the identification of financial risks can be improved, and the study of real estate financial risks can be strengthened. The article uses a combination of multivariate statistics and grey fuzzy theory to complete the study of real estate financial risks. Therefore, through the exploration of multivariate statistics and grey fuzzy theory, its application value can be elevated.

Abstract
Objective: To use metagenomic sequencing to compare the differences in intestinal microbiota species and metabolic pathways in patients with hepatitis B cirrhosis with or without ascites and further explore the correlation between the differential microbiota and clinical indicators and metabolic pathways. Methods: 20 hepatitis B cirrhosis cases [10 without ascites (HBLC-WOA), 10 with ascites (HBLC-WA), and 5 healthy controls (HC)] were selected from the previously studied 16S rRNA samples. Metagenome sequencing was performed on the intestinal microbiota samples. The Kruskal-Wallis rank sum test and Spearman test were used to identify and analyse differential intestinal microbiota populations, metabolic pathways, and their correlations. Results: (1) The overall structure of the intestinal microbiota differed significantly among the three groups (R = 0.19, P = 0.018). The HC group had the largest abundance of Firmicutes and the lowest abundance of Proteobacteria at the genus level. Firmicutes abundance was significantly decreased (P(fdr) < 0.01), while Proteobacteria abundance was significantly increased (P(fdr) < 0.01) in patients with cirrhosis accompanied by ascites; (2) LEfSe analysis revealed that 29 intestinal microbiota (18 in the HBLC-WA group and 11 in the HBLC-WOA group) played a significant role in the disease group. The unclassified Enterobacteriaceae and Klebsiella species in the HBLC-WA group and Enterobacteriaceae in the HBLC-WOA group were positively correlated with the Child-Turcotte-Pugh (CTP) score, prothrombin time, and international normalized ratio score and negatively correlated with albumin and hemoglobin levels (P < 0.05). Escherichia and Shigella in the HBLC-WA group were positively correlated with CTP scores (P < 0.05); (3) The correlation analysis results between the KEGG pathway and 29 specific intestinal microbiota revealed that Enterobacteriaceae and arachidonic acid, α-linolenic acid, glycerolipid metabolism, and fatty acid degradation were positively correlated in the lipid metabolism pathway, while most Enterobacteriaceae were positively correlated with branched-chain amino acid degradation and negatively correlated with aromatic amino acid biosynthesis in the amino acid metabolic pathway. Conclusion: A significant increment of Enterobacteriaceae in the intestines of HBLC-WA patients influenced hepatic reserve function and was associated with amino acid and lipid metabolic pathways. Therefore, attention should be paid to controlling the intestinal microbiota to prevent complications and improve the prognosis in patients with hepatitis B cirrhosis, especially in those with ascites.

Abstract
Objective: To investigate the changes of CTCs and the correlation between the changes of CTCs and the clinical efficacy of neoadjuvant immunotherapy for non-small cell lung cancer (NSCLC). Methods: A retrospective case-control study was conducted to collect the data of 23 patients with NSCLC who received neoadjuvant immunotherapy in the Third Xiangya Hospital from June 2018 to December 2019. They were 35-76 years old with a median age of 52 years old, including 13 male patients and 10 female patients. The CTCs value, evaluation results from response evaluation criteria in solid tumor (RECIST) and major pathological response were evaluated before treatment, after neoadjuvant immunotherapy and after operation. Mann Whitney U test was used for the comparison between the two groups, Wilcoxon test was used for the comparison of association samples, and Kruskal Wallis test was used for the comparison between multiple samples. Results: The CTCs value was positively correlated with tumor progression, that the CTCs value of ⅡB group, ⅢA group and ⅢB group was 10.69 (3.87) FU/3 ml, 12.90 (2.24) FU/3 ml and 16.04 (3.43) FU/3 ml, and the difference was statistically significant (χ2=7.829, P=0.020). Then CTCs decreased to 7.60(4.79) FU/3 ml significantly (Z=4.197,P=0.000), and decreased to 6.22(2.80) FU/3 ml significantly again after surgery(Z=-2.950,P=0.005). In RECIST results, the CTCs value of CR group, PR group and SD group was 12.90(3.79)FU/3 ml, 12.52(3.96) FU/3 ml and 13.58(5.11) FU/3 ml,and no significant difference before treatment (χ²=1.806, P=0.405). After neoadjuvant immunotherapy, the CTCs of CR group decreased to 6.22(3.87) FU/3 ml significantly (Z=-4.950, P= 0.000), and also PR group to7.32(4.31) FU/3 ml (Z=-3.180, P=0.001) or SD group to (Z=-2.023, P=0.043). There was no significant difference between CR group and PR group (Z=-0.838, P=0.402), but significant difference between SD group and CR/PR group (Z=-1.922, P=0.050). After operation, the CTCs of CR, PR and SD group decreased to 6.09(3.43) FU/3 ml, 6.40(1.82) FU/3 ml and 9.20(5.16) FU/3 ml,and there was no significant difference to preparation in CR group and PR group, but significant difference in SD group (Z=-2.023, P=0.043). There was no significant difference between CR group and PR group (Z=-1.134, P=0.257), but significant difference between SD group and CR/PR group (Z=-1.624, P=0.014). Before treatment,CTCs of MPR group and non-MPR group were 11.98(4.14) FU/3 ml and 13.54(4.76) FU/3 ml,and there was no significant difference between them (Z=-1.354, P=0.176). After neoadjuvant immunotherapy, the CTCs of MPR group decreased to 6.36(2.65) FU/3 ml significantly (Z=-2.934, P=0.001) and also in non-MPR group to 10.88(2.80) FU/3 ml (Z=-2.840, P=0.003); but there was significant difference between MPR group and non-MPR group (Z=-3.693, P=0.000), and also the change of CTCs between two groups (Z=-2.770, P=0.006). After operation, the CTCs of MPR group decreased to 5.40(1.33) FU/3 ml insignificantly (Z=-0.533, P=0.594) but significantly to 7.05(3.80) FU/3 ml in non-MPR group (Z=-2.734, P=0.030), and significant difference between them (Z=-1.900, P=0.011). Conclusion: The value of CTCs is negatively correlated with the efficacy (RECIST and MPR) of neoadjuvant immunotherapy for NSCLC, which can be used for clinical efficacy evaluation of neoadjuvant immunotherapy.

Abstract
This study aimed to establish nomograms to preoperatively predict the possibility of testicular salvage (TS) in patients with testicular torsion. The clinical data of 204 patients with testicular torsion diagnosed at Xijing Hospital and Tangdu Hospital (Xi'an, China) between August 2008 and November 2019 were retrospectively analyzed. Univariate and multivariate logistic regression analyses were used to determine the independent predictors of TS. Based on multivariate regression coefficients, nomograms to predict possibility of TS were established. The predictive ability of the nomograms was internally validated by receiver operating characteristic (ROC) curves and calibration plots. The duration of symptoms ranged from 2 h to 1 month, with a median of 3.5 days. Thirty (14.7%) patients underwent surgical reduction and contralateral orchiopexy, while the remaining 174 (85.3%) underwent orchiectomy and contralateral orchiopexy. Finally, long symptom duration was an independent risk predictor for TS, while visible intratesticular blood flow and homogeneous testicular echotexture under color Doppler ultrasound were independent protective predictors. Internal validation showed that the nomograms, which were established by integrating these three predictive factors, had good discrimination ability in predicting the possibility of TS (areas under the ROC curves were 0.851 and 0.828, respectively). The calibration plots showed good agreement between the nomogram-predicted possibility of TS and the actual situation. In conclusion, this brief preoperative prediction tool will help clinicians to quickly determine the urgency of surgical exploration.

Abstract
BACKGROUND To investigate the functions of the hyperpolarization-activated cation currents in medium-size dorsal root ganglion cells in a rat model of overactive bladder syndrome. METHODS Rats with OAB were screened using a urodynamic testing device. The whole-cell patch clamp technique was used to investigate changes in excitability and hyperpolarization-activated cation current (Ih) of medium-size cells in the L6 dorsal root ganglia (DRG) of the OAB rats. Intrathecal injection of the specific Ih inhibitor ZD7288 was used to investigate changes of voiding function and Ih of medium-size cells in the L6 DRG. RESULTS The urinary bladder weight of the OAB rats was significantly increased (p < 0.01); However, 7 days after intrathecally administration of ZD7288 (2 μM), the weight of rat bladder was significantly reduced (p < 0.01). The excitability of the medium-size cells in the L6 DRG of the OAB rats was significantly increased, and the number of action potentials elicited by a 500 pA stimulus was also markedly increased. Furthermore, ZD7288 significantly reduced the excitability of the medium-size DRG cells. The medium-size cells in the DRG of the OAB rats had a significantly increased Ih current density, which was blocked by ZD7288. CONCLUSIONS The Ih current density significantly increased in medium-size cells of the L6 DRG in the OAB model. A decrease of the Ih current was able to significantly improve the voiding function of the OAB rats, in addition to lowering their urinary bladder weight. Our finding suggested that the observed increase of Ih current in the medium-size DRG neurons might play an important role in the pathological processes of OAB.

Abstract
Constipation has a significant influence on quality of life. Patients with constipation have slow waves in their gastrointestinal smooth muscles and less faecal water contents, which are closely associated with down-regulation of the interstitial cells of Cajal (ICC) in the gastrointestinal muscles and the aquaporin protein AQP3 expressed in colon epithelial cells. Recent studies supported that patients with constipation have altered intestinal microbial structures compared with healthy controls. Intestinal dysbiosis might be one possible pathophysiological mechanism causing constipation. Bacterial strains, such as Lactobacillus spp., have shown many beneficial effects on the amelioration of constipation. However, few studies reported the structural changes of intestinal microbiota post-intervention of probiotics. In this study, a bacterial mixture was administrated to rats with loperamide-induced constipation. Effects of the bacterial mixture on small intestine transit (SIT), faecal water content, and the intestinal microbiome in rats were evaluated. Meanwhile, we investigated several factors involved in signalling pathways that regulate function of ICC and expression of AQP3 to discuss the possible underlying molecular mechanisms. Intervention of the bacterial mixture improved SIT and faecal water content in constipated rats. The up-regulation of C-kit/SP signalling pathways in ICC and AQP3 significantly contributed to improvements. These changes were closely associated with the manipulation of intestinal dysbiosis in constipated rats. Furthermore, our results revealed the important role of intestinal microbiota in affecting gut motility through regulation of serotonin biosynthesis. This monoamine neurotransmitter, secreted from enterochromaffin cells, up-regulated both substance P/neurokinin 1 receptors pathway of ICC and the expression of AQP3 in intestinal epithelial cells. Our study suggested that the disrupted microbiome in patients could be a potential therapeutic target for the improvement of constipation.

Abstract
BACKGROUND Although triptorelin is increasingly used in China for biochemical castration, its effects on primary prostate cancer symptoms remain unclear. This study aimed to assess the prevalence of lower urinary tract symptoms (LUTS) in Chinese prostate cancer patients and the effectiveness of triptorelin on LUTS. METHODS In this 48-week multicenter, non-interventional, prospective study, we enrolled patients with locally advanced or metastatic prostate cancer. Patients received triptorelin (15 mg) intramuscularly at baseline and at weeks 12, 24, and 36 with symptom assessment using the International Prostate Symptoms Score (IPSS). The primary endpoints were the prevalence of LUTS at baseline per IPSS categories and the percentage of patients with moderate to severe LUTS (IPSS > 7) at baseline, having at least a 3-point reduction of IPSS score at week 48. RESULTS A total of 398 patients were included; 211 (53.0%) and 160 (40.2%) among them had severe and moderate LUTS, respectively. Of the patients with IPSS scores available at baseline and at week 48 (n = 213), 81.2% achieved a reduction in IPSS of at least 3 points. Of the patients with moderate to severe LUTS at baseline and IPSS scores available at baseline and at week 48 (n = 194), 86.6% achieved a total IPSS reduction of at least 3 points. CONCLUSIONS The vast majority of Chinese patients with locally advanced or metastatic prostate cancer scheduled to receive triptorelin as part of their standard treatment have severe or moderate LUTS. Triptorelin therapy resulted in sustained improvement of LUTS in these patients.

Abstract
Macrophages, characterized by considerable diversity and plasticity, play a crucial role in a broad spectrum of biological processes, including inflammation. However, the molecular mechanisms underlying the diverse phenotypes of macrophages are not well defined. Here, we show that the RNA-binding protein, quaking (QKI), dynamically modulates macrophage polarization states. After lipopolysaccharide (LPS) stimulation, QKI-silenced RAW 264.7 cells displayed a pro-inflammatory M1 phenotype characterized by increased expression of iNOS, TNF-α, and IL-6 and decreased expression of anti-inflammatory factors, such as IL-10, found in inflammatory zone (Fizz1), and chitinase-like 3 (Chil3 or Ym1). By contrast, QKI5 overexpression led to a suppressive phenotype resembling M2 macrophages, even under M1 differentiation conditions. Moreover, myeloid-specific QKI-deficient mice tended to be more susceptible to LPS-induced endotoxic shock, while the exogenous transfer of macrophages overexpressing QKI5 exerted a significant improving effect. This improvement corresponded to a higher proportion of M2 macrophages, in line with elevated levels of IL-10, and a decrease in levels of pro-inflammatory mediators, such as IL-6, TNF-α, and IL-1β. Further mechanistic studies disclosed that QKI was a potent inhibitor of the nuclear factor-kappa B (NF-κB) pathway, suppressing p65 expression and phosphorylation. Strikingly, reduced expression of the aryl hydrocarbon receptor (Ahr) and reduced phosphorylation of signal transducer and activator of transcription 1 in QKI-deficient cells failed to restrain the transcriptional activity of NF-κB and NRL pyrin domain containing 3 (NLRP3) activation, while restoring QKI expression skewed the above M1-like response toward an anti-inflammatory M2 state. Taken together, these findings suggest a role for QKI in restraining overt innate immune responses by regulating the Ahr/STAT1–NF-κB pathway.

Abstract
Background To evaluate anti-prostate cancer effects of a chimeric tumor-targeted killer protein. Methods We established a novel fusion gene, immunocasp-3, composed of NH2-terminal leader sequence fused with an anti-prostate-specific membrane antigen (PSMA) antibody (J591), the furin cleavage sequences of diphtheria toxin (Fdt), and the reverse coding sequences of the large and small subunits of caspase-3 (revcaspase-3). The expressing level of the immunocasp-3 gene was evaluated by using the reverse transcription-PCR (RT-PCR) and western blot analysis. Cell viability assay and cytotoxicity assay were used to evaluate its anti-tumor effects in vitro. Apoptosis was confirmed by electron microscopy and Annexin V-FITC staining. The antitumor effects of immunocasp-3 were assessed in nude mice xenograft models containing PSMA-overexpressing LNCaP cells. Results This study shows that the immunocasp-3 proteins selectively recognized and induced apoptotic death in PSMA-overexpressing LNCaP cells in vitro, where apoptotic cells were present in 15.3% of the cells transfected with the immunocasp-3 expression vector at 48 h after the transfection, in contrast to 5.5% in the control cells. Moreover, LNCaP cells were significantly killed under the condition of the co-culture of the immunocasp-3-secreting Jurkat cells and more than 50% of the LNCaP cells died when the two cell lines were co-cultured within 5 days. In addition, The expression of immunocasp-3 also significantly suppressed tumor growth and greatly prolonged the animal survival rate in vivo. Conclusion A novel fusion gene, immunocasp-3, may represent a viable approach to treating PSMA-positive prostate cancer.

Abstract
Transgene silencing, which is common in transgenic plants and animals, limits the generation and application of genetically modified organisms, and is associated with the exogenous gene copy number, the methylation status of its promoters, and histone modification abnormalities. Here, we analyzed the expression of the exogenous gene DsRed and the methylation status of its cytomegalovirus (CMV) promoter in six healthy transgenic cashmere goats and transgenic nuclear donor cells. The CMV promoter exhibited high methylation levels (74.4-88.2%) in four of the goats, a moderate methylation level (58.7%) in one, and a low methylation level (21.2%) in one, while the methylation level of the transgenic nuclear donor cells was comparatively low (14.3%). DsRed expression was negatively correlated with promoter methylation status. Transgenic cashmere goats carried one to three copies of the CMV promoter fragment and one to six copies of the DsRed fragment, but copy number showed no obvious correlation with DsRed expression. After treatment with the methylation inhibitor 5-azacytidine, DsRed expression in transgenic goat cells significantly increased and CMV promoter methylation significantly decreased; this indicated an inverse correlation between promoter methylation status and DsRed expression. After treatment with the histone deacetylase inhibitor trichostatin A, DsRed expression increased, indicating that an abnormal histone modification in transgenic goats is also involved in exogenous gene silencing. These findings indicate the potential of trichostatin A and 5-azacytidine to rescue the biological activity of silenced exogenous transgenes in adult-derived transgenic cells under culture conditions.

Abstract
Percent free prostatic-specific antigen (%fPSA) has been introduced as a tool to avoid unnecessary biopsies in patients with a serum PSA level of 4.0–10.0 ng ml−1, however, it remains controversial whether %fPSA is effective in PSA range of 10.1–20.0 ng ml−1 in both Chinese and Western population. In this study, the diagnostic performance of %fPSA and serum PSA in predicting prostate cancer (PCa) and high-grade PCa (HGPCa) was analyzed in a multi-center biopsy cohort of 5915 consecutive Chinese patients who underwent prostate biopsy in 22 hospitals across China from January 1, 2010 to December 31, 2013. The indication for biopsy was PSA>4.0 ng ml−1 or/and suspicious digital rectal examination. Total and free serum PSA determinations were performed by three types of electrochemiluminescence immunoassays with recalibration to the World Health Organization standards. The diagnostics accuracy of PSA, %fPSA and %fPSA in combination with PSA (%fPSA + PSA) was determined by the area under the receivers operating characteristic curve (AUC). %fPSA was more effective than PSA in men aged ≥60 years old. The AUC was 0.584 and 0.635 in men aged ≥60 years old with a PSA of 4.0–10.0 ng ml−1 and 10.1–20.0 ng ml−1, respectively. The AUC of %fPSA was superior to that of PSA in predicting HGPCa in patients ≥60 years old in these two PSA range. Our results indicated that %fPSA is both statistically effective and clinical applicable to predict prostate biopsy outcome in Chinese patients aged ≥60 years old with a PSA of 4.0–10.0 ng ml−1 and 10.1–20.0 ng ml−1.

Abstract
Background We analyzed the expression of heme oxygenase-1 (HO-1) in patients undergoing radical nephrectomy for advanced clear cell renal cell carcinoma (CC-RCC) and evaluated the effects of the targeted therapies treated with sorafenib and sunitinib. Methods Expression of HO-1 in cancer tissue from 66 patients was measured by immunohis-tochemical staining. The patients received either oral sorafenib (n=40) or oral sunitinib (n=26) within 4 weeks after nephrectomy and were followed up long term to determine the tumor response and prognosis. Results Our current study revealed a high HO-1 expression level in 57.6% (38/66) of patients and a low HO-1 expression level in 42.4% (28/66) of patients with CC-RCC. The study also revealed that patients with high HO-1 expression did not have a higher objective response rate (2.6% versus 53.6%, P<0.01), clinical benefit rate (47.4% versus 92.9%, P<0.01), longer progression-free survival (4.4 versus 42 months, P=0.022), or overall survival (χ2=4.775, P=0.029) than patients with low HO-1 expression. In the low HO-1 level group, a higher tumor response rate and a longer survival time was achieved in patients who received sorafenib or sunitinib. Multivariate analysis showed that HO-1 expression was an independent prognostic factor for tumor response and overall survival. Conclusion High expression of HO-1 was associated with a lower tumor response rate and a shorter overall survival time when compared with low expression of HO-1. Overall, HO-1 expression might be a useful biomarker for predicting the response to sunitinib and sorafenib for patients with metastatic CC-RCC.

Abstract
Although radical nephrectomy alone is widely accepted as the standard of care in
localized treatment for renal cell carcinoma (RCC), it is not sufficient for the
treatment of metastatic RCC (mRCC), which invariably leads to an unfavorable outcome
despite the use of multiple therapies. Currently, sequential targeted agents are
recommended for the management of mRCC, but the optimal drug sequence is still
debated. This case was a 57-year-old man with clear-cell mRCC who received multiple
therapies following his first operation in 2003 and has survived for over 10 years
with a satisfactory quality of life. The treatments given included several surgeries,
immunotherapy, and sequentially administered sorafenib, sunitinib, and everolimus
regimens. In the course of mRCC treatment, well-planned surgeries, effective
sequential targeted therapies and close follow-up are all of great importance for
optimal management and a satisfactory outcome.

Abstract
OBJECTIVE To assess the feasibility and safety of robot-assisted laparoscopic radical prostatectomy (RLRP) in the treatment of prostate cancer. METHODS Using the da Vinci robot surgical system, we performed RLRP for 34 patients with localized prostate cancer and analyzed the intraoperative and follow-up data. RESULTS The procedures were performed successfully in all the patients, with the mean operation time of 198 min (range 135-340 min), average blood loss of 257 ml (range 50-700 ml), and 1 case of blood transfusion, but no postoperative complications. Three cases had positive surgical margins. Postoperative examination at 4 weeks showed PSA > 0.2 microg/L in 2 cases, suggestive of residual tumor, for which maximal androgen block therapy was administered. The other 32 patients were followed up for 3-10 (mean 7.5) months, during which the average level of serum tPSA remained < 0.2 microg/L. Urinary continence was found in 94% (32/34) and 97% (33/34) of the patients at 3 and 6 months, respectively, of whom 77% (26/34) and 88% (30/34) had no urinary leakage (0 pad per day). CONCLUSION RLRP, with its advantages of less perioperative blood loss, low rate of positive margin, and good urinary continence, is a safe and effective surgical option for the treatment of prostate cancer.

Abstract
Although CD44 was overexpressed and considered as a useful prognostic marker in renal cell carcinoma, the prognostic role of CD44s in clear cell renal cell carcinoma (ccRCC) remains controversial. Moreover, the correlation and prognostic significance of CD44s and its downstream signaling target pSTAT3 are unclear in ccRCC. In this study, 75 pairs of carcinoma and paired adjacent non-tumor renal tissue samples were collected from patients with localized ccRCC who underwent a nephrectomy. The expression levels of CD44s and pSTAT3 were analyzed using immunohistochemistry. Correlations between CD44s/pSTAT3 expression and clinical and pathological characteristics were determined using x(2) test, Kaplan-Meier analysis and Cox's proportional hazards model. We found that CD44s is highly expressed in 46.67% of tumor tissues, and its high expression was significantly associated with high tumor grade (P < 0.001), large tumor size (P = 0.009) and advanced T stage (P = 0.004). A strong correlation exists between high expression of CD44s and pSTAT3 (r = 0.4013, P = 0.0004). The joint over expression of CD44s and pSTAT3 was present in 42.66% of tumor specimens and had an additive negative impact on overall survival. Patients with CD44s(high)pSTAT3(high) expression had significantly poor survival as compared to patients with CD44s(low)pSTAT3(low) tumor expression (P = 0.024), though the concurrent overexpression of CD44s and pSTAT3 was not an independent prognostic factor for overall survival. Our data indicate that expression of both CD44s and pSTAT3 in ccRCC is associated with advanced tumor stage and patient survival. The conclusions from this study may improve the prediction of ccRCC prognosis information when CD44s and pSTAT3 expression are evaluated together with classical clinicopathological parameters.

Abstract
HeLa cells were exposed to formaldehyde and its metabolic derivatives, methanol, formic acid, and acetaldehyde, to investigate that the toxicity of formaldehyde is not caused by the chemical group. After 1 h of treatment with formaldehyde, mitochondrial assays showed that low concentrations (e.g. 10 μmol/L) of formaldehyde promoted growth of the HeLa cells, while higher concentrations (e.g. ≥62.5 μmol/L) inhibited cell growth; while all four chemicals at a concentration of 125 μmol/L affected cell growth, formaldehyde affected the largest. Reactive oxygen species concentration increased with the concentration of the exposure chemical. The endogenous formaldehyde content increased the most in the formaldehyde group, but in other three groups, it did not increase as the exposure concentration increased. Expression of dehydrogenase (formaldehyde dehydrogenase (FDH)) in the formaldehyde (10.40) and methanol (10.60) groups increased significantly compared with the control (1), while it was similar to the control in formic acid (0.90) and acetaldehyde (1.10) groups. Our results suggest that formaldehyde could affect cell activity and even enter cells. Exposure to formaldehyde changes the endogenous formaldehyde concentration in cells within 24 h, and this induces expression of FDH for formaldehyde degradation to maintain the formaldehyde balance. The toxicity of formaldehyde is not caused by the carbon atoms in the aldehyde, hydroxyl, or carboxyl groups. Formaldehyde is hypothesized to be an important signaling molecule in the regulation of cell growth and maintenance of the endogenous formaldehyde level.

Abstract
Increased expression of CARMA3 has been reported to be involved in tumorigenesis and tumor progression of several cancer types. The aim of our study is to investigate the prognostic role of CARMA3 expression in patients with renal cell carcinoma (RCC). Real-time quantitative PCR was performed to detect CARMA3 mRNA expression level in 31 paired samples of RCC and adjacent noncancerous renal tissues. Subsequently, extensive immunohistochemistry was performed to detect CARMA3 protein expression in 114 RCC cases. Clinicopathological data for these patients were evaluated. The prognostic significance was assessed using the Kaplan-Meier survival estimates and log-rank tests. CARMA3 mRNA expression was significantly higher in RCC tissues compared with adjacent noncancerous renal tissues (3.525 ± 1.233 vs. 1.512 ± 0.784, P < 0.001). In addition, high CARMA3 expression in RCC tissues was significantly associated with tumor size (P = 0.026), histological differentiation (P = 0.039), tumor stage (P = 0.006), and the presence of metastasis (P < 0.001). Moreover, Kaplan-Meier analysis showed that patients with high CARMA3 expression also had a significantly poorer prognosis than those with low CARMA3 expression (log-rank test, P < 0.001). Furthermore, multivariate analysis illustrated that CARMA3 overexpression might be an independent prognostic indicator for the survival of patients with RCC. In conclusion, this work shows that CARMA3 may serve as a novel and prognostic marker for RCC and play a role during the development and progression of the disease.

Abstract
This study aimed to assess the efficiency and effects of insulin-like growth factor receptor-1 (IGF-IR) siRNA knockdown during bovine preimplantation embryonic development. In oocytes injected with IGF-IR siRNA, the relative IGF-IR mRNA levels compared to controls were 28% and 46% at 6 and 24 h after injection, respectively. With respect to the injection of IGF-IR siRNA in zygotes, 24 h after injection the relative levels of IGF-IR mRNA and protein in the two-cell embryos were 74% and 78% of those in the controls, respectively. IGF-IR siRNA reduced blastocyst formation (23.2%) compared to siRNA controls (33.0%) and uninjected oocytes (35.4%; P < 0.05) and the number of viable cells per IGF-IR siRNA-treated blastocyst (64 ± 3) was significantly reduced, compared to control siRNA and uninjected blastocysts (81 ± 3 and 116 ± 4; P < 0.01). In conclusion, IGF-IR siRNA knockdown reduces the development of bovine embryos, and microinjection in zygotes can decrease blastocyst cell number.

Abstract
OBJECTIVE To evaluate the safety and efficacy of intraperitoneal anatomical radical nephrectomy (IARN). METHODS A retrospective analysis was performed for 60 consecutive patients undergoing IARN at our hospital from March 2007 to December 2009. Various clinical parameters were collected and analyzed statistically. RESULTS Sixty operations were performed successfully. There was neither conversion into open surgery nor blood transfusion. The mean operative time was (106 ± 23) min, mean intraoperative estimated blood loss (112 ± 37) ml, mean time of resuming oral intake (2.1 ± 0.7) d, mean time to ambulation (1.9 ± 1.1) d, mean postoperative analgesics (pethidine) dosage (65 ± 25) mg, average drainage volume 100 (50 - 300) ml, mean time of extracting drainage tube (3.6 ± 1.3) d and mean postoperative hospital stay (9.4 ± 2.1) d. CONCLUSION IARN offers the advantages of distinct anatomical level, shorter operative time, less hemorrhage, less damage, faster postoperative recovery and a lower rate of complications.

Abstract
N-myc downstream regulated gene 2 (NDRG2) is involved in invasion and metastasis of cancer, furthermore it is frequently down-regulated in prostate cancer. Herein we evaluated the effect of NDRG2 overexpression on invasiveness and bone destruction in prostate cancer. The human prostate cancer cell line PC-3 and DU145 were infected with Ad-NDRG2 or Ad-LacZ. Overexpression of NDRG2 not only inhibited the growth of the cells, but also suppressed invasiveness of the cells in an in vitro assay. PC-3 cells infected with Ad-NDRG2 or Ad-LacZ were injected into the tibias of nude mice. Four weeks later, we found the mice injected with PC-3 cells overexpressing NDRG2 had smaller tumors and less bone destruction. These results demonstrate that NDRG2 overexpression can inhibit tumor growth and invasion, furthermore, it can decrease bone destruction caused by prostate cancer bone metastasis.

Abstract
OBJECTIVE To investigate the expressions of cadherin molecules CDH18 and PCDH17 in normal and azoospermic human testes and their significance. METHODS We studied the routine pathological slices of normal and non-obstructive azoospermic human testis tissues for changes in the tight junction of Sertoli-germ cells, and identified the differential gene expression profiles of the normal and azoospermic testis tissues using cDNA microarrays containing multiple cadherin molecules. The results were confirmed by Western blot. RESULTS Abnormal tight junction of the Sertoli-germ cells was observed in 37.5% of the azoospermic testis samples, and obvious changes were seen in the expressions of some cadherin molecules, with down-regulation of CDH18 and PCDH17. CONCLUSION Cadherin molecules such as CDH18 and PCDH17 may play a certain role in the development and progression of azoospermia, which might be related with the abnormal tight junction of the Sertoli-germ cells.

Abstract
OBJECTIVE To evaluate the expression of COX10 mRNA in the testes of non-obstructive azoospermia patients and normal men. METHODS A cDNA microarray containing COX10 and some other genes as RBM and EIF1AY was used to identify the differential gene expression profiles in the normal and azoospermic testes. The cDNA probes were prepared by labeling mRNA from azoospermic and normal testis tissues with Cy5-dUTP and Cy3-dUTP respectively through reverse transcription. The mixed cDNA probes were then hybridized with cDNA microarray. Later the fluorescent signals were scanned and the values of Cy5-dUTP and Cy3-dUTP on each spot were calculated and analyzed. After that an ISH was employed to detect the expression of COX10 mRNA in 10 fertile and 39 non-obstructive azoospermic testes, and the expression levels were compared to evaluate the significance. RESULTS We obtained 128 differentially expressed genes that might be related with azoospermia, among which 56 were up-regulated and 72 down-regulated, with the expression of COX10 significantly decreased. In situ hybridization confirmed that the mRNA expression of COX10 was stronger in the spermatogenic cells of the normal fertile than the azoospermic testes. CONCLUSION COX10 may play a certain role in the development and progression of azoospermia. The technique of cDNA microarray can be applied to further studies of screening non-obstructive azoospermia associated genes.

Abstract
The aim of this study was to explore the mechanism underlying the dual effect of androgen on prostate cancer cells and further explore its correlation with dopa decarboxylase (DDC), an androgen receptor (AR) coactivator and a traditional neuroendocrine differentiation (NED) marker. Cell proliferation and cycling after treatment with synthetic nonmetabolizable androgen R1881 was determined by the MTT (3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl tetrazolium bromide) method and flow cytometry. Differential gene expression was analyzed by cDNA microarrays. DDC expression during the dual effect of R1881 was further explored with microarray, quantitative reverse transcriptase-polymerase chain reaction (RT-PCR), Western blot, and enzyme activity assays. Proliferation of LNCaP cells was inhibited by 1 nM R1881 but stimulated by 0.1 nM R1881. Compared with the untreated cells, 320 (2.26%; 170 up-regulated, 150 down-regulated) and 4608 (32.65%; 2046 up-regulated, 2562 down-regulated) genes were found to be expressed differentially in the 1 nM and 0.1 nM R1881-treated cells, respectively. The results were partially confirmed by RT-PCR and Western blot. The DDC gene was down-regulated in the 1 nM R1881-treated cells and up-regulated in 0.1 nM R1881- and 30 nM hydroxyflutamide-treated cells. The enzymatic activity of DDC in the latter 2 groups was also strengthened. Meanwhile, the NED markers CgA and synaptophysin were not affected by these AR activators. R1881 had a dose-dependent biphasic effect on LNCaP cell proliferation. AR coactivator DDC was respectively down- and up-regulated in high and low concentrations of R1881. DDC up-regulation by exogenous AR activators is not accompanied by up-regulation of definitive NED markers.

Abstract
With increased use of intensity-modulated radiation therapy (IMRT) for head and neck treatment questions have arisen as to selection of an optimum treatment approach when either superficial sparing or treatment is desired. Other work has pointed out the increased superficial dose resulting from obliquity effects when multiple tangential beams are applied to head and neck treatment, as is the general case in IMRT planning. Helical tomotherapy might be expected to result in even further enhanced superficial dose compared with conventional bilateral field treatment. We have designed a typical right oropharynx target volume in an anthropomorphic head and neck phantom. Three different treatment techniques have been used to optimally treat this target, including bilateral static fields, eight-field IMRT and helical tomotherapy. The phantom was immobilized in a standard treatment position and treated on a Varian 2300cd linear accelerator and on a Hi-Art Helical Tomotherapy unit. 1 mm3 lithium-fluoride thermoluminescent dosimeters (TLDs) were placed on the surface of the phantom at a number of axial test positions. Film strips (Kodak EDR2) were either wrapped around the surface or sandwiched within the phantom. Measured doses at the surface and as a function of depth are compared with the planning system predictions for each treatment technique. The maximum surface doses on the proximal treatment side, averaged from TLDs and films, were measured to be 69-82% of the target dose with the bilateral fields yielding the lowest surface doses (69%), tomotherapy about 2% more than that (71%) and IMRT 13% more (82%). Anterior to the target volume, doses are always low for bilateral treatment. In this case the minimum anterior surface dose (chin area) was 6% of the prescription dose from that technique as compared with 26% and 35% from the IMRT and tomotherapy methods, respectively. The Eclipse and Tomotherapy planning systems both modelled deep and superficial doses well. Surface doses were better modelled by Eclipse at the test points, while the tomotherapy plans consistently overestimated the measured doses by 10% or more. Depth dose measurements, extracted from embedded films, indicated the depth of dose build-up to >99% to be the shallowest for IMRT (2-5 mm) followed by tomotherapy (5-8 mm) and bilateral fields (10-15 mm). The amount of surface dose is clearly technique dependent and should be taken into account in the planning stage.

Abstract
OBJECTIVE To study the differential gene expression profiles between the normal and aspermia human testes by genechips. METHODS Probes were prepared from mRNA extracted from both normal and aspermia testes and employed on Biostar H-40s genechips to detect the differential gene expression profiles. A distinctly up-regulated gene RAP1A was analyzed by bibliogrphic retrieval. RESULTS Six hundred and twenty-three differential expressed genes were found, among which the distinctly up-regulated gene RAP1A was closely related to human sperm regulation. CONCLUSIONS Screening the differential gene expression profiles between the normal and aspermia human testes by genechips can be used in the study of aspermia-related genes.

Abstract
AIM To establish a renal carcinoma cell line which can highly express beta-glucuronidase(betaG), and to observe the biological characteristics of the transfected cells. METHODS Recombinant eukaryotic expression vector pcDNA3.1-betaG was constructed. It was transfected into renal cancer cells GRC-1 via liposome. The transcription and expression of betaG gene were detected by dot blot and Western blot. The biological characteristics of the betaG gene transfected cells was observed under light microscope, transmission electron microscope and flow cytometry. RESULTS Dot blot and Western blot detection confirmed that the betaG gene had been stably integrated into the genomic DNA of the GRC-1 cells and was highly expressed. Transmission electron microscope observation showed that the lysosomes and endoplasmic reticulum were abundant, the number of microvili and process was significantly increased in the transfected cells, but growth condition and cell cycle of GRC-1 cells had no notable difference before and after transfection. CONCLUSION A renal carcinoma cell line that can highly express betaG gene was established, which lays the foundation for further study on gene therapy.

To study the escaping behavior of 1030 schizophrenic in-patients, "Brief Rating Scale for Dangerous Behavior of In-patient" was used to asses them within their first week hospitalization from May 1994 to March 1996. The result showed that 276 (26.8%) patients had escaping behavior. The patients with paranoid schizophrenia had higher rate of escaping behavior. There was no correlation being found between sex, age, duration of illness, and escaping behavior. The patients with the history of such behavior were more likely to escape from ward (41.9%). The suggestion for preventing such behavior were discussed.

Abstract
By random screening test, Marsdenia koi was found to have antifertility activity on SD rat. From MeOH extracts of this plant two steroidal glycosides, marsdekoiside A and B, were isolated, and their structures were elucidated on the basis of spectral evidence and by comparison of the hydrolysis products with the authentic samples. Both are newly identified compounds, and marsdekoiside A has good antifertility activity.
