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
Studies of the neurobiological causes of anxiety disorders have suggested that the γ-aminobutyric acid (GABA) system increases synaptic concentrations and enhances the affinity of GABAA (type A) receptors for benzodiazepine ligands. Flumazenil antagonizes the benzodiazepine-binding site of the GABA/benzodiazepine receptor (BZR) complex in the central nervous system (CNS). The investigation of flumazenil metabolites using liquid chromatography (LC)-tandem mass spectrometry will provide a complete understanding of the in vivo metabolism of flumazenil and accelerate radiopharmaceutical inspection and registration. The main goal of this study was to investigate the use of reversed-phase high performance liquid chromatography (PR-HPLC), coupled with electrospray ionization triple-quadrupole tandem mass spectrometry (ESI-QqQ MS), to identify flumazenil and its metabolites in the hepatic matrix. Carrier-free nucleophilic fluorination with an automatic synthesizer for [18F]flumazenil, combined with nano-positron emission tomography (NanoPET)/computed tomography (CT) imaging, was used to predict the biodistribution in normal rats. The study showed that 50% of the flumazenil was biotransformed by the rat liver homogenate in 60 min, whereas one metabolite (M1) was a methyl transesterification product of flumazenil. In the rat liver microsomal system, two metabolites were identified (M2 and M3), as their carboxylic acid and hydroxylated ethyl ester forms between 10 and 120 min, respectively. A total of 10-30 min post-injection of [18F]flumazenil showed an immediate decreased in the distribution ratio observed in the plasma. Nevertheless, a higher ratio of the complete [18F]flumazenil compound could be used for subsequent animal studies. [18F] According to in vivo nanoPET/CT imaging and ex vivo biodistribution assays, flumazenil also showed significant effects on GABAA receptor availability in the amygdala, prefrontal cortex, cortex, and hippocampus in the rat brain, indicating the formation of metabolites. We reported the completion of the biotransformation of flumazenil by the hepatic system, as well as [18F]flumazenil's potential as an ideal ligand and PET agent for the determination of the GABAA/BZR complex for multiplex neurological syndromes at the clinical stage.

Abstract
The Arg–Gly–Asp (RGD) peptide shows a high affinity for αvβ3 integrin, which is overexpressed in new tumor blood vessels and many types of tumor cells. The radiolabeled RGD peptide has been studied for cancer imaging and radionuclide therapy. We have developed a long-term tumor-targeting peptide DOTA-EB-cRGDfK, which combines a DOTA chelator, a truncated Evans blue dye (EB), a modified linker, and cRGDfK peptide. The aim of this study was to evaluate the potential of indium-111(111In) radiolabeled DOTA-EB-cRGDfK in αvβ3 integrin-expressing tumors. The human glioblastoma cell line U-87 MG was used to determine the in vitro binding affinity of the radiolabeled peptide. The in vivo distribution of radiolabeled peptides in U-87 MG xenografts was investigated by biodistribution, nanoSPECT/CT, pharmacokinetic and excretion studies. The in vitro competition assay showed that 111In-DOTA-EB-cRGDfK had a significant binding affinity to U-87 MG cancer cells (IC50 = 71.7 nM). NanoSPECT/CT imaging showed 111In-DOTA-EB-cRGDfK has higher tumor uptake than control peptides (111In-DOTA-cRGDfK and 111In-DOTA-EB), and there is still a clear signal until 72 h after injection. The biodistribution results showed significant tumor accumulation (27.1 ± 2.7% ID/g) and the tumor to non-tumor ratio was 22.85 at 24 h after injection. In addition, the pharmacokinetics results indicated that the 111In-DOTA-EB-cRGDfK peptide has a long-term half-life (T1/2λz = 77.3 h) and that the calculated absorbed dose was safe for humans. We demonstrated that radiolabeled DOTA-EB-cRGDfK may be a promising agent for glioblastoma tumor imaging and has the potential as a theranostic radiopharmaceutical.

Abstract
Objective: To investigate the therapeutic effects of surgical management for local retroperitoneal recurrence of renal cell carcinoma after radical nephrectomy. Methods: Clinical and follow-up data of 33 cases of local recurrence after radical nephrectomy in Renji Hospital from January 2010 to April 2018 were retrospectively analyzed. Results: In these 33 patients, 25 was male and 8 was female; The median age was 54 years old. The pathological stage of radical nephrectomy included 14 cases of pT1-2N0M0 stage, 16 cases of pT3-4 N0M0 stage, and 3 cases of pN1 stage. Only 4 relapsing patients had symptoms, the others were all found to have recurrence by imaging examination during follow up period of postoperation.The median recurrence time for all patients was 30 months, and the median diameter of recurrent tumors was 4.5 cm.Twenty-nine patients underwent complete resection of local recurrent lesions, and 4 patients whose recurrent lesions could not be completely resected converted receive palliative surgery. The median intraoperative blood loss was 500 ml and the median hospital stay after surgery was 4 days. Clavien grade Ⅰ-Ⅱ complications occurred in 5 patients after surgery, and no serious complications of Clavien grade Ⅲ-Ⅴ complications occurred. Six patients received postoperative adjuvant target therapy and distant metastasis occurred in one patient.In the 27 patients without adjuvant target therapy, postoperative distant metastases occurred in 12 patients. The median survival time for all patients after local recurrence surgery was 31 months. The 1-year and 3-year survival rates were 86.8% and 36.9%, respectively. Conclusions: The rigorous imaging examination after radical nephrectomy can detect local recurrent lesions as early as possible in most relapsing patients and imaging examination can predict the integrity of surgical resection of local recurrence.Although intraoperative bleeding of resection of local recurrence is relatively high, the operation is safe and the postoperative complications are controllable. Postoperative adjuvant therapy may also provide better survival benefit for patients with local recurrence.

Abstract
Objective:This study was aimed to compare the long-term effects of house dust mite (HDM) subcutaneous immunotherapy (SCIT) in a cohort of Chinese pediatric and adult patients with allergic rhinitis (AR).Method:Total of 48 AR patients received standardized HDM-SCIT for 3 years, and they received 3 years of standardized dust mite-specific subcutaneous immunotherapy, followed by 2 years after treatment. Prior to treatment (baseline) and at the end of the 3-year and 5-year treatment periods, all patients were evaluated for total nasal symptom scores(TNSS),total combined score (TCS;symptoms(nasal+ocular)+daily medication score),and rhinoconjunctivitis quality of life questionnaire(RQLQ).Safety of HDM-SCIT was assessed according to adverse events reported.Result:Fifteen pediatric and 33 adult AR patients completed the study.HDM-SCIT significantly improved symptoms and RQLQ scores at the 3 rd year and 5th year in both children and adults. Superior efficacy was observed at the 3-year and 5-year timepoints in children compared to adults. The safety of HDM-SCIT was comparable in children and adults with AR.Conclusion:A 3-year course of HDM-SCIT is an effective, safe and sustainable long-term treatment in both pediatric patients and adults with AR, although children appear to achieve better long-term efficacy compared to the adults.

Abstract
Nonspecific nasal hyperreactivity (NHR) has been widespread observed in patients with allergic rhinitis (AR) and nonallergic rhinitis (NAR). As a clinical hallmark, NHR is more common in patients with NAR. The cold dry air (CDA) can stimulate nasal symptoms such as rhinorrhea and nasal obstruction, and the CDA provocation test can be used as a reliable objective method to evaluate NHR. The mechanism of CDA-induced nasal symptoms is very complicated and thus it has not yet been fully illuminated. The innervation of the nasal nerves includes sensory nerve (trigeminal ganglion), sympathetic nerve (superior cervical ganglion) and parasympathetic nerve (sphenopalatine ganglion). CDA innervation may also be associated with these nerves and associated signal pathway. Recently, general attention has been focused on the transient receptor potential (TRP) channel, including TRP vanilloid-1 (TRPV1) and TRP ankyrin-1 (TRPA1). More relevant researches are needed to further clarify the mechanism.

Abstract
BACKGROUND Management of high-grade T1 (formerly T1G3) bladder cancer continues to be controversial. Should patients with T1G3 bladder cancer have an immediate radical cystectomy or should they receive intravesical bacillus Calmette-Guérin preserving bladder? Gemcitabine and cisplatin (GC) adjuvant chemotherapy may help to strike a balance between intravesical and early cystectomy. For purposes of this study, we continue to refer high-grade T1 lesion as "T1G3." OBJECTIVE To evaluate the characteristics and the long-term outcome of GC adjuvant chemotherapy in T1G3 bladder cancer after transurethral resection of bladder tumor (TURBT). MATERIALS AND METHODS We, retrospectively, reviewed 48 patients who were newly diagnosed with T1G3 bladder cancer between January 2009 and December 2012. A total of 48 patients received 4 cycles of GC adjuvant chemotherapy after TURBT. One month after 4 cycles of GC adjuvant chemotherapy, response was evaluated by re-TURBT. Median follow-up was 59.5 (range: 18-70) months, all patients have been observed for more than 3 years. Salvage cystectomy was recommended for patients with persistent disease and for tumor progression after initial complete response. RESULT Complete response was achieved in 44 (91.7%) patients. Of complete responders, 5 patients experienced recurrence and 5 patients showed progression. The progression rate and disease-specific survival rate were 10.4% and 91.7% at 3 years, respectively. More than 80% of survivors preserved their bladder. Kaplan-Meier curves showed that concomitant carcinoma in situ (CIS) was the only factor that had an influence on progression-free survival (P = 0.022) and disease-specific survival (P = 0.017). Concomitant CIS was the prognostic factor for progression rate and disease-specific survival rate at 3 years (P = 0.008 and P = 0.035). CONCLUSION GC adjuvant chemotherapy is a safe conservative treatment for T1G3 bladder cancer, but effective is really a phase II study. Patients with T1G3 bladder cancer with concomitant CIS should be treated more aggressively because of the high risk of progression.

Objective: To investigate the efficacy and drug related adverse reactions of sorafenib and sunitinib as first-line tyrosine-kinase inhibitors (TKIs) for patients with metastatic renal cell carcinoma (mRCC) and analyze the clinical prognostic factor for survival. Methods: The data of 271 patients with metastatic renal cell carcinoma who had complete clinicopathological data were retrospectively analyzed, including 174 cases in sorafenib group and 97 cases in sunitinib group, to access patients' overall survival (OS) and progression-free survival (PFS). Prognostic values of all characteristics were determined by using univariate and multivariate Cox regression models. Results: The objective response rates (ORR) of the sorafenib and sunitinib groups were 14.9% and 19.6%, respectively, and the disease control rates (DCR) were 85.1% and 88.6%, respectively. No significant difference was found between the sorafenib and sunitinib group in ORR (P=0.325) or DCR (P=0.408). The most common grade 3 to 4 adverse events in the sorafenib group were hand-foot syndrome (6.7%), diarrhea (2.3%), and rash (2.3%). The most common grade 3 to 4 adverse events in the sunitinib group were neutropenia (6.2%), hand-foot syndrome (6.2%), and thrombocytopenia (4.6%). During the follow-up, 97 cases death occurred and 81 cases disease progression occurred in sorafenib group. The median PFS was 12 months (95% CI: 9-15 months), and the median OS was 25 months (95% CI: 21-29 months) in sorafenib group. While 74 cases death occurred and 40 cases disease progression occurred in sunitinib group, the median PFS was 12 months (95% CI: 10-12 months) and the median OS was 23 months (95% CI: 20-32 months) in sunitinib group. No significant difference was found between the sorafenib and the sunitinib group in PFS (P=0.771) or OS (P=0.548). Multivariate analysis showed Fuhrman grades (HR=1.358, 95%CI: 1.004-1.835), number of metastatic sites (HR=1.550, 95%CI: 1.143-2.101) and MSKCC risk grade (Intermediate risk group: HR=1.621, 95%CI: 1.117-2.232; Poor risk group: HR=2.890, 95%CI: 1.942-4.298) were independent prognostic factors for PFS. Fuhrman grades (HR=2.135, 95%CI: 1.533-2.974), number of metastatic sites (HR=1.774, 95%CI: 1.279-2.461) and MSKCC risk grade (Intermediate risk group: HR=1.415, 95%CI: 1.002-1.998; Poor risk group: HR=3.161, 95%CI: 2.065-4.838) were independent prognostic factors for OS. Conclusions: The results of this study indicate that sorafenib and sunitinib are both effective as the first-line TKIs for mRCC patients and sorafenib has comparable efficacy to sunitinib. But they have differences in the incidence of adverse effects. Fuhrman grades, number of metastatic sites and MSKCC risk grade are independent prognostic factors for mRCC patients.

Abstract
OBJECTIVE To assess perineural invasion in prostatectomy specimen(PNIp)on tumor progression and prognosis after radical prostatectomy. METHODS Retrospective analysis including 502 prostate cancer patients admitted in Renji Hospital, School of Medicine, Shanghai Jiaotong University from December 2002 to May 2014 was studied.Differences of serum prostate specific antigen(PSA), Gleason score of prostate biopsy, Gleason score of prostatectomy specimen, tumor stage, capsular invasion, positive surgical margin, seminal invasion, pelvic lymph node metastasis, nadir PSA were analyzed in patients with PNIp and without PNIp. Logistic regression analysis, Log-rank test and Cox regression analysis was used to analyzed the data, respectively. RESULTS There were 91 patients with PNIp(18.1%) and 411 patients without PNIp(81.9%). Differences of serum PSA, Gleason score of prostate biopsy, Gleason score of prostatectomy specimen, tumor stage, capsular invasion, seminal invasion, nadir PSA between the two groups were found(all P<0.05). In the multivariable logistic regression analysis, PNIp was independent predictor of Gleason score of prostate biopsy, Gleason score of prostatectomy specimen, tumor stage, capsular invasion(OR=1.515, 1.955, 2.069, 1.859, all P<0.05). One hundred and twenty-one patients with biochemical serum recurrence(26.7%). Serum PSA, Gleason score of prostate biopsy, Gleason score of prostatectomy specimen, tumor stage, PNIp, seminal invasion were related to biochemical serum recurrence(P<0.05). In the multivariable cox regression analysis, serum PSA, Gleason score of prostate biopsy, PNIp, seminal invasion were independent predictors of biochemical serum recurrence(HR=1.021, 1.441, 1.663, 3.257, all P<0.05). CONCLUSION PNIp is the important predictor of the tumor progression and prognosis of prostate cancer.

Abstract
To evaluate the effect of Schisandrol A on rabbit corpus cavernosum smooth muscle and elucidate the potential mechanism. Penises were obtained from healthy male New Zealand White rabbits (2.5-3.0 kg). The pre-contracted penis with phenylephrine (Phe, 10 µM) was treated with accumulative concentrations of Schisandrol A (10-7, 10-6, 10-5 and 10-4 M). The change in intracavernosum pressure (ICP) and tension was recorded, cyclic nucleotides in the cavernosum tissue were measured by radioimmunoassay, mRNA level and expression of endothelial nitric oxide synthase (eNOS) and neuronal NOS (nNOS) were measured by real time PCR and western blot respectively. The corpus cavernosum smooth muscle relaxation induced by Schisandrol A was in a dose-dependent manner. Pre-treatment with NOS inhibitor (Nω nitro-L-arginine-methyl ester, L-NAME) or guanylyl cyclase inhibitor (1H-(1,2,4)oxadiazolo(4,3-a)quinoxalin-1-one, ODQ) significantly diminished the relaxation. The cyclic guanosine monophosphate (cGMP) level was significantly increased in the cavernosum tissue. Real time PCR and western blot showed the mRNA level and expression of eNOS and nNOS was also upregulated. Schisandrol A relaxes the cavernosum smooth muscle by activating NO-cGMP signaling pathway. It may be a new promising treatment for erectile dysfunction and cardiovascular disease.

Abstract
OBJECTIVES This research aims to specify the prognostic value of P-cadherin on recurrence and progression in non-muscle-invasive bladder cancers (NMIBC). METHODS A total of 110 NMIBC cases were collected and P-cadherin protein was assessed by immunohistochemical test in these samples. Correlations between P-cadherin expression and clinicopathologic features were analyzed. For recurrence-free and progression-free survival, Kaplan-Meier log-rank test was used. Then Cox univariate and multivariate analyses were further performed. RESULTS P-cadherin high expression correlated with tumor progression (P = 0.031). Kaplan-Meier results showed that patients with high P-cadherin expression had worse progression-free survival (P = 0.034) but not recurrence-free survival (P = 0.133) than low-expression patients. Cox regression results showed P-cadherin expression was an independent predictor for progression (P = 0.042) but not recurrence (P = 0.139) in NMIBC. CONCLUSIONS Our results demonstrated that P-cadherin expression correlated with tumor progression and could be taken as an independent predictor for progression in NMIBC.

Abstract
PURPOSE This study was carried out to examine P53-induced Ring-h2 protein (Pirh2) expression and investigate its clinical and prognostic significance in patients with clear cell renal cell carcinoma (ccRCC). METHODS Pirh2 mRNA and protein expressions were detected by quantitative reverse-transcription polymerase chain reaction (Q-RT PCR) and Western blotting in 35 frozen renal cancer tissue specimens and 35 adjacent normal renal tissue specimens of the same patients. Pirh2 protein expression was assessed by immunohistochemical analysis in 92 paraffin-embedded specimens of human ccRCC and 30 specimens of adjacent normal renal tissue. Correlations between Pirh2 and clinicopathologic features and prognosis were analyzed statistically. RESULTS Pirh2 mRNA and protein levels in ccRCC samples were increased significantly as compared with the adjacent normal renal tissues (P < 0.001). Pirh2 mRNA overexpression correlated with high stage and grade of the renal cancer (P < 0.001 and P < 0.001 respectively). Pirh2 protein expression was negative in most normal renal tissue specimens (23/30) but positive in 52.2% (48/92) of ccRCC specimens (P = 0.006). Pirh2 protein expression correlated with tumor grade and stage (P < 0.001 and P < 0.001 respectively). The median follow-up interval was 42.0 months. Overexpression of Pirh2 protein in ccRCC was significantly associated with shorter overall survival and recurrence-free survival (P = 0.001 and P = 0.003, respectively). Multivariate analysis showed that Pirh2 expression was an independent prognostic factor for ccRCC patients (P = 0.037). CONCLUSIONS Pirh2 was up-regulated in ccRCC at both transcriptional and translational levels compared with normal renal tissues, suggesting that Pirh2 may be a potential prognostic marker for ccRCC.

Abstract
PURPOSE [(123)I]Epidepride is a radio-tracer with very high affinity for dopamine D(2)/D(3) receptors in brain. The importance of alteration in dopamine D(2)/D(3) receptor binding condition has been wildly verified in schizophrenia. In the present study we set up a rat schizophrenia model by chronic injection of a non-competitive NMDA receptor antagonist, MK-801, to examine if [(123)I]epidepride could be used to evaluate the alterations of dopamine D(2)/D(3) receptor binding condition in specific brain regions. METHOD Rats were given repeated injection of MK-801 (dissolved in saline, 0.3mg/kg) or saline for 1month. Afterwards, total distance traveled (cm) and social interaction changes were recorded. Radiochemical purity of [(123)I]epidepride was analyzed by Radio-Thin-Layer Chromatography (chloroform: methanol, 9:1, v/v) and [(123)I]epidepride neuroimages were obtained by ex vivo autoradiography and small animal SPECT/CT. Data obtained were then analyzed to determine the changes of specific binding ratio. RESULT Chronic MK-801 treatment for a month caused significantly increased local motor activity and induced an inhibition of social interaction. As shown in [(123)I]epidepride ex vivo autoradiographs, MK-801 induced a decrease of specific binding ratio in the striatum (24.01%), hypothalamus (35.43%), midbrain (41.73%) and substantia nigra (37.93%). In addition, [(123)I]epidepride small animal SPECT/CT neuroimaging was performed in the striatum and midbrain. There were statistically significant decreases in specific binding ratio in both the striatum (P<.01) and midbrain (P<.05) between the saline and MK-801 group. CONCLUSION These results suggest that [(123)I]epidepride is a useful radio-tracer to reveal the alterations of dopamine D(2)/D(3) receptor binding in a rat schizophrenia model and is also helpful to evaluate therapeutic effects of schizophrenia in the future.

Abstract
PURPOSE To examine HMGA2 expression and investigate its clinical and prognostic significance in human urothelial bladder cancer (BUC). METHODS We detected HMGA2 mRNA and protein expression by quantitative reverse-transcription polymerase chain reaction and western blotting, respectively in 44 frozen bladder cancer tissues and 18 adjacent normal bladder tissues. HMGA2 protein expression was assessed by immunohistochemical analysis of 148 paraffin-embedded specimens of human BUC and 30 specimens of adjacent normal bladder tissue. Correlations between HMGA2 and clinicopathologic features and prognosis were tested by statistical analyses. RESULTS HMGA2 mRNA and protein levels in bladder cancer samples were significantly increased compared with adjacent normal bladder tissues (P < 0.001). mRNA overexpression correlated with high stage and grade of the bladder cancer (P < 0.001 and P = 0.002 respectively). HMGA2 protein expression was negative in all normal urothelial tissue samples, but positive in 52% (77/148) of bladder cancers (P < 0.001). HMGA2 expression correlated with tumor grade and stage (P < 0.001 and P = 0.003 respectively), Overexpression of HMGA2 protein in non-muscle-invasive bladder cancer was significantly associated with shorter recurrence-free survival (P < 0.001), and progression-free survival (P = 0.0004). Multivariate analysis showed that HMGA2 expression was an independent prognostic factor for both tumor recurrence (P < 0.001) and tumor progression (P = 0.006). CONCLUSIONS HMGA2 is up-regulated in bladder cancer at both the transcriptional and translational levels compared with normal bladder tissue, HMGA2 protein is thus a potential prognostic marker for predicting tumor recurrence and progression.

Abstract
The main purpose of the present work is to predict from benchmark many-body quantum mechanical calculations the results of experimental studies of the valence electronic structure of dimethoxymethane employing electron momentum spectroscopy, and to establish once and for all the guidelines that should systematically be followed in order to reliably interpret the results of such experiments on conformationally versatile molecules. In a first step, accurate calculations of the energy differences between stationary points on the potential energy surface of this molecule are performed using Hartree-Fock (HF) theory and post-HF treatments of improving quality (MP2, MP3, CCSD, CCSD(T), along with basis sets of increasing size. This study focuses on the four conformers of this molecule, namely the trans-trans (TT), trans-gauche (TG), gauche-gauche (G+G+), and gauche-gauche (G+G-) structures, belonging to the C2v, C1, C2, and Cs symmetry point groups, respectively. A focal point analysis supplemented by suited extrapolations to the limit of asymptotically complete basis sets is carried out to determine how the conformational energy differences at 0 K approach the full CI limit. In a second step, statistical thermodynamics accounting for hindered rotations is used to calculate Gibbs free energy corrections to the above energy differences, and to evaluate the abundance of each conformer in the gas phase. It is found that, at room temperature, the G+G+ species accounts for 96% of the conformational mixture characterizing dimethoxymethane. In a third step, the valence one-electron and shake-up ionization spectrum of dimethoxymethane is analyzed according to calculations on the G+G+ conformer alone by means of one-particle Green's function [1p-GF] theory along with the benchmark third-order algebraic diagrammatic construction [ADC(3)] scheme. A complete breakdown of the orbital picture of ionization is noted at electron binding energies above 22 eV. A comparison with available (e,2e) ionization spectra enables us to identify specific fingerprints of through-space orbital interactions associated with the anomeric effect. At last, based on our 1p-GF/ADC(3) assignment of spectral bands, accurate and spherically averaged (e,2e) electron momentum distributions at an electron impact energy of 1200 eV are computed from the related Dyson orbitals. Very significant discrepancies are observed with momentum distributions obtained for several outer-valence levels using standard Kohn-Sham orbitals.

Abstract
AIM AND METHODS To evaluate the protective effects of hypoxic preconditioning (HPC) on myocardial energy metabolism, Langendorff-perfused hearts, exposed to HPC, were subjected to hypoxia/reoxygenation (5/10 min). 31P NMR was used to sequentially follow the time courses of high energy phosphates (HEP) contents and intracellular pH (pHi) of the rat myocardium. RESULTS The Contents of Phosphocreatine (PCr), Adenosine Triphosphate (ATP) and the PCr/Pi (inorganic phosphate) ratios decreased during 30 min hypoxia, but the reduction was slower for the HPC group compared with Control. Reoxygenation induced recovery of myocardial HEP in both groups, HPC enhanced t he recovery especially in initial stage o f reoxygenation. However, pHi change was not significant for HPC group in this experiment. CONCLUSION HPC improves the myocardial energy metabolism level during prolonged hypoxia and subsequent reoxygenation and protects myocardium against hypoxia/reoxygenation injury.

Abstract
Recently, we developed a novel triaryl-substituted pyrazole ligand system that has high affinity for the estrogen receptor (ER) (Fink, B. E.: Mortenson, D. S.: Stauffer, S. R.; Aron, Z. D.: Katzenellenbogen, J. A. Chem. Biol. 1999, 6, 205). Subsequent work has shown that some analogues in this series are very selective for the ERalpha subtype in terms of binding affinity and agonist potency (Stauffer, S. R.: Coletta, C. J.: Tedesco. R.: Sun, J.: Katzenellenbogen, J. A. J. Med. Chem. 2000, submitted). We now investigate how this pyrazole ER agonist system might be converted into an antagonist or a selective estrogen receptor modifier (SERM) by incorporating a basic or polar side chain like those typically found in antiestrogens and known to be essential determinants of their mixed agonist/antagonist character. We selected an N-piperidinyl-ethyl chain as a first attempt, and introduced it at the four possible sites of substitution on the pyrazole core structure to determine the orientation that the pyrazole might adopt in the ER ligand binding pocket. Of these four, the C(5) piperidinyl-ethoxy-substituted pyrazole 5 had by far the highest affinity. Also, it bound to the ER subtype alpha (ERalpha) with 20-fold higher affinity than to ERbeta. In cell-based transcription assays, pyrazole 5 was an antagonist on both ERalpha and ERbeta, and it was also more potent on ERalpha. Based on structure-binding affinity relationships and on molecular modeling studies of these pyrazoles in a crystal structure of the ERalpha-raloxifene complex, we propose that pyrazoles having a basic substituent on the C(5) phenyl group adopt a binding mode that is different from that of the pyrazole agonists that lack this group. The most favorable orientation appears to be one which places the N(1) phenol in the A-ring binding pocket so that the basic side chain can adopt an orientation similar to that of the basic side chain of raloxifene.

AIM AND METHODS To assess the myocardial effects of Salvia Miltiorrhiza (SM) injection against hypoxia-reoxygenation injury, 31P NMR was used to trace the time courses of high energy phosphates (HEP) content and intracellular pH (pHi) of the isolated perfused rat hearts under hypoxia (30 min) and subsequent reoxygenation (40 min). RESULTS It was discovered that SM significantly preven-ted the decrease in the myocardial HEP content during hypoxia, enhanced the recovery of myocardial phosphocreatine (PCr), adenosine triphosphate (ATP) and the PCr/Pi (inorganic phosphate) ratios during reoxygenation, and lightened the decrease of the myocardial pHi value caused by hypoxia. CONCLUSION SM improves the myocardial energy metabolism level during prolonged hypoxia and subsequent reoxygenation and protects myocardium against hypoxia/reoxygenation injury. SM significantly attenuates acidosis during hypoxia and prevents the appearance of very acidic areas of the myocardium after reoxygenation.

Abstract
Laryngospasm occurring after tracheal extubation in children is potentially dangerous. This study uses acupuncture with bloodletting at the Shao Shang (L 11) or Shang Yang (Li 1) acupoints to investigate whether this technique can prevent or treat laryngospasm. Seventy-six patients were randomly divided into two groups. Patients in the acupuncture group (n = 38) were treated with bilateral Shao Shang acupunctures at the end of the operation. Patients in the control group (n = 38) were not. The incidence of laryngospasm in the acupuncture group (5.3%) was less than that in the control group (23.7%) (p < 0.05). If laryngospasm developed, patients were immediately treated with acupuncture at either the Shao Shang or Shang Yang acupoints. As judged by an increase in peripheral oxygen saturation, the laryngospasm was relieved within 1 min of acupuncture in all patients. It is concluded that acupuncture with bloodletting at the Shao Shang acupoint may prevent and treat laryngospasm occurring after tracheal extubation in children.

Abstract
BACKGROUND This study was conducted to determine whether the paranasal extension of a primary non-Hodgkin's lymphoma (NHL) of the nasal cavity has any deleterious effect on patient outcome. METHODS One hundred and seventy-five patients with previously untreated nasal NHL were reviewed. There were 2 with low grade, 107 with intermediate grade, 17 with high grade, and 49 with unclassifiable lymphomas. In 48 cases the immunophenotype was available and 46 were T-cell lymphoma. According to the Ann Arbor system, there were 133 patients with Stage IE, 28 with Stage IIE, 4 with Stage IIIE, and 10 with Stage IVE lymphomas. Stage IE was subdivided into limited Stage IE (i.e., confined to the nasal cavity [67 patients]) or extensive Stage IE (i.e., presenting with extension beyond the nasal cavity [66 patients]). For patients with limited Stage IE disease the treatment of choice was radiotherapy with or without chemotherapy. In patients with extensive Stage IE disease, treatment was comprised of a combination of chemotherapy and radiotherapy or radiotherapy alone. For patients with a more advanced stage of disease (IIE-IVE), chemotherapy was an integral part of the treatment and was completed by irradiation, especially for patients with Stage IIE disease. RESULTS The actuarial overall survival (OS) and disease free survival (DFS) rates at 5 years for the whole group were 65% and 57%, respectively. The 5-year OS and DFS rates were influenced by stage, with a gradual decrease from 75% and 68% for Stage IE disease to 35% and 28% for Stage IIE disease, and 31% and 19% for Stage IIIE/IVE disease. Patients with limited Stage IE disease survived significantly longer (90% 5-year OS) compared with those with extensive Stage IE disease (57% 5-year OS; P < 0.001). For 67 patients with limited Stage IE disease, the 5-year OS was 89% with radiotherapy alone and 92% with radiotherapy and chemotherapy, whereas for 66 patients with extensive Stage IE disease, the 5-year OS was 54% with radiotherapy and 58% with combined modality therapy or chemotherapy (P > 0.05). CONCLUSIONS The prognosis of patients with primary NHL of the nasal cavity is stage dependent. In this large cohort of Stage IE patients, it was demonstrated that the paranasal local extension was a significant prognostic factor associated with poorer treatment outcome. The authors believe that Ann Arbor Stage IE should be subclassified further into limited and extensive Stage IE. The addition of chemotherapy did not appear to modify significantly the survival of patients with either limited or extensive Stage IE disease. The extranodal progression observed in patients with extensive Stage IE and Stage IIE-IVE disease clearly illustrates the need for improvement of systemic treatment.

Abstract
Sleep quality and psychical health were investigated with Pittsburgh Sleeping Quality Index (PSQI) and SCL-90 in 128 patients with hyperthyroidism. The results showed that: 1. The PSQI scores of the patients with ages over 35 years old were higher than that less than 35 years old (P < 0.05). 2. Sleep problems occurred in 87.55% of the patients. Sleep quality of 9.38% of patients were worse. The sleep quality of the female patients were better than the male (P < 0.05). 3. Apart from interpersonal sensitivity, paranoid ideation and psychoticism, scores of the rest were higher than the general people (P < 0.05). 10.2% of the patients with hyperthyroidism had psychical problems. 4. Apart from sleep time and using sleep pill, there was a high correlation between the scores of SCL-90 and PSQI (P < 0.05-P < 0.001). The results showed that sleep problems of the patients with hyperthyroidism affected their psychical health. Lower sleep quality was a main dangerous factor which affected psychical health of the patients with hyperthyroidism.

Abstract
PURPOSE The purpose of this study was to analyze prognosis and treatment results for seminoma arising in corrected and uncorrected inguinal cryptorchidism (SCIC and SUIC). METHODS AND MATERIALS We reviewed 66 patients with inguinal seminomas between June 1958 and December 1991 at the Cancer Hospital and Institute of Chinese Academy of Medical Sciences. Of these patients, 23 had prior orchiopexy and 43 presented with an inguinal form of cryptorchidism. At presentation, 17 of 66 (26%) patients had nodal metastases. This nodal involvement was 30% (7 of 23) for SCIC and 23% (10 of 43) for SUIC, respectively. These numbers are comparable with those in a series of patients treated for scrotal seminoma at our institution (26% vs. 20%). However, 3 of 23 (13%) patients who had prior orchiopexy presented with inguinal nodal metastasis as compared with 0 of 43 patients with SUIC or 4 of 237 patients with scrotal seminoma (p < .05). There were 49 stage I, 5 stage IIA, 8 stage IIB, 3 stage III, and 1 stage IV patients. All patients underwent radical orchiectomy and received further radiotherapy, chemotherapy, or both. Patients with stage I and stage II disease were treated primarily with radiotherapy, whereas patients with stage III and IV disease were treated with chemotherapy. RESULTS The overall and disease-free survival at 5 and 10 years was 94% and 92%, 89% and 87%, respectively. The overall 5- and 10-year survival by stage was 100% and 100% for stage I, and 77% and 68% for stage II, respectively (p < .05). There was no significant difference in survival between SUIC and SCIC (93% vs. 96% at 5 years). Four patients developed relapse. Two of these four patients experienced relapse at the inguinal area, due to a marginal miss. Three of four patients with relapse were successfully salvaged, and one died of disease. CONCLUSION Our results indicate that prognosis for inguinal seminoma is excellent and similar to that of scrotal seminoma. Postorchiectomy radiotherapy can be considered as the standard treatment for stage I and IIA inguinal seminoma. We recommend routinely including the para-aortic and ipsilateral pelvic nodes.

Abstract
PURPOSE To analyze the clinical characteristics, prognosis, and treatment outcome of pelvic cryptorchid seminoma (PCS), and to determine whether whole abdominal-pelvic irradiation for Stage I disease is necessary. METHODS AND MATERIALS From 1958 to 1991, 60 patients with PCS were treated at the Cancer Hospital of Chinese Academy of Medical Sciences, Beijing. They presented with a lower abdominal mass and showed a predominance for the right side. A high proportion of patients with PCS [26 of 60 (43%)] had metastatic disease, compared to 20% of those with scrotal seminoma, and there was a tendency toward a higher frequency of pelvic nodal metastases. There were 34 Stage I, 6 Stage IIA, 11 Stage IIB, 5 Stage III, and 4 Stage IV patients. Of these 60 patients, 56 underwent laparotomy with or without cryptorchiectomy (37 radical orchiectomy, 7 partial orchiectomy, and 12 biopsy of the primary or cervical node), and 4 cervical node biopsy only. All patients were further treated with radiotherapy, chemotherapy, or a combination of both. Patients with Stage I and II disease received radiotherapy, whereas patients with Stage III and IV were treated with chemotherapy. RESULTS The overall and disease-free survivals at 5 and 10 years were 92% and 87%, and 88% and 84%, respectively. The 5- and 10-year survivals were 100% for Stage I, 94% and 87% for Stage II, and 56% and 42% for Stage III/IV, respectively (p < 0.05). Volume of irradiation, i.e., whole abdominal-pelvic radiotherapy (10 patients), versus hockey-stick encompassing paraaortic, ipsilateral iliac nodes and the primary tumor or tumor bed (17) did not influence outcome in Stage I patients. Five patients relapsed within 2-12 years after treatment, and four of these patients were successfully salvaged. Four patients developed a second malignant tumor and died. CONCLUSION Stage I and II PCS can be adequately controlled by radiotherapy regardless of the surgical procedure. Whole abdominal-pelvic irradiation for Stage I and IIA disease is not required, and fields can be limited to the paraaortic, ipsilateral iliac nodes and primary tumor or tumor bed. We recommend platinum-based chemotherapy for Stage IIB-IV PCS.

Abstract
From June 1983 to Jan. 1985, 75 patients with early stage non-Hodgkin's lymphoma were treated in our hospital. The ages ranged from 3 to 65 years. The ratio of male to female was 2.75. The intermediate and high grade malignant lymphoma comprised 89.3% of the whole group. By clinical staging, there were 23 Stage I, 44 Stage II, and 8 Stage III lesions. The primary sites were: 33 in the Waldeyer's ring, 22 in lymph nodes, 10 in the nasal cavity and 10 in the other organs. The two-year survival rate of the whole group was 69.3%. In view of the results, the prognosis was related to the staging, A or B symptoms, primary site and CR or PR after treatment, but the age was irrelevant. The results also showed that intermediate or high grade malignancy gave no significant difference in the two-year survival rate. It might be due to the fact that they were originated from the large cell type of lymphoma in the intermediate group and possessed similar malignant properties as the high grade lymphoma.

Abstract
This paper reports 40 patients with primary gastric malignant lymphoma as proved by pathology and treated in our hospital from October 1958 to December 1984. There were 20 males and 20 females, including 3 Hodgkin's disease and 37 non-Hodgkin's lymphoma. The patients were treated by surgery, radiotherapy and chemotherapy separately or combined. In this series, the 5 and 10 year survival rates were 48.6% and 47.6%. The combination of surgery with postoperative radiotherapy and/or chemotherapy gave better results. In postoperative radiation to the whole abdomen, the tissue dose should not be less than 30-35 Gy. The incidence, diagnosis, clinical staging and the indication of primary gastric malignant lymphoma are discussed with a review of literature.

Abstract
Clinical, X-ray and pathological materials of 21 cases of primary non-Hodgkin's lymphoma (NHL) of the stomach were reviewed. According to NHL classification--working formulation for clinical usage sponsored by NCI, USA, there were 13 (61.9%) intermediate grade, 6 (28.6%) high grade and 2 (9.5%) low grade malignant lymphomas. By X-ray manifestations, they were classified into 5 types: multinodular type (4 cases), infiltrative (4), ulcerative (3), giant rugal (1) and mixed (9). Clinically, 10 lesions were stage I, 4 stage II, 1 stage III and 4 stage IV, 2 unclassified. The median survivals were 101 months for stage I, 15 months for stage II and less than 6 months for stages III and IV. The 5 and 10 year survival rates were 70% and 40% in stage I patients. The prognosis is related to clinical stage, depth of the tumor infiltration and histology type but not related to the tumor size or X-ray manifestations.

Abstract
From Mar. 1958 through 1985, 50 male patients with breast cancer were treated in our hospital. The ratio of male and female with primary breast cancer was 1:90 during the same period. All were proven by pathology except one case. Forty seven have been followed for more than 5 years. There were 12 stage I lesions, 19 stage II and 16 stage III. Radical mastectomy was performed in 22 patients, total mastectomy in 11 and lobectomy in 12, supplemented by radiotherapy, chemotherapy, hormonal therapy or their combination. Two were not indicated for surgery and were only given a combination combination therapy without operation. The irradiation after radical mastectomy was to deliver to the regional lymph nodes and for the rest, a dose of 5,000-6,000 cGy/5-6 weeks should be added to the chest wall. The chemotherapy, including Thio-TEPA, 5-fluorouracil, cyclophosphamide and methotrexate etc, in the form of single or multi-drug for 1-3 courses, was given. The overall 5 and 10 year survival rates were 51% and 22.5%. The 5 year survival rates of stage I, II and III patients were 83%, 53% and 25%. The 5 year survivals of radical mastectomy, total mastectomy and lobectomy combined with radiotherapy, chemotherapy and hormonal therapy were 59%, 27% and 67%. In those who failed, 50% developed local recurrence or regional metastasis or both and 60% had extensive dissemination. The results indicate that the combination therapy comprising radical mastectomy and lobectomy has a good prognosis. The authors believe that the male breast cancer is more hormone-dependent than the female breast cancer, orchiectomy plays an important role in the treatment of advanced lesions.

Abstract
A series of 60 patients with malignant lymphoma was proved by pathology except two with mediastinal lesions. All were admitted for radiotherapy from Oct, 1979 to June 1983 and the abdomen was scanned by CT. There were 29 cases of Hodgkin's disease (HD) and 31 of non-Hodgkin's lymphoma (NHL). The age ranged from 8 to 69 years 5 were scanned before, 32 during and 23 after treatment. The results showed that 18 patients had subdiaphragmatic lesions, of which 10 were HD and 8 NHL. The sites of the 18 positive abdominal scan were 9 lymphatic involvement (para-aortic, coeliac, splenic-hilar, mesenteric, gastric, hepatic-hilar, diaphragmatic posterior group and presacral) and 3 visceral involvement (liver, spleen and adrenal gland). As to the change in clinical staging of malignant lymphoma after CT scan, 5 patients (26%) with stage I were downed to stages II and III; 6 (22%) with stage II to stages III, IV and 1 stage III to stage IV. Altogether 22% of stages I, II and III were down staged. According to our experiences, abdominal CT scan can not take the place of exploration or lymphography because the small lesions in the spleen and liver are not visible on the CT scans using conventional intravenous water soluble contrast media. Lymphography is more accurate in showing the retroperitoneal lymph nodes. The CT scan is valuable in detecting lesions in the upper para-aortic, mesenteric, splenic-hilar, hepatic-hilar and renal-hilar lymph nodes.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
This paper reports 35 patients treated for giant cell tumor of bone. Ten patients were treated by surgery followed by postoperative irradiation. All 10 were cured; eight have survived for more than 5 years and four for more than 10 years without recurrence. Twenty-five patients were treated by radiation alone. All patients were followed for 2 to 17 years. For those who received more than 3500 rad, the local control rate was 82% (14/17); for those who received more than 4000 rad, the local control rate was 85% (11/13). Thirteen have lived for more than 5 years and nine have lived for more than 10. Our experience reveals that surgery and postoperative radiation produce the best results, and that these results are better than those reported in the literature. The results of radiation alone are comparable to that of surgery. For lesions not amenable to surgery, or those which would become crippling if surgery is attempted, radiation should be used either alone or in combination with conservative surgery. The dose for radiation alone should be 5000 to 6000 rad and for postoperative radiation, 3000 to 4000 rad. Supervoltage X rays (60Co or 8 Mv X ray), but not orthovoltage X rays, are indicated. A single radiation course with higher dose is preferred to multiple courses with lower doses. In 62% (15/24) of patients, pain relief begins before treatment is completed. In 74% (14/19) of patients, the tumor mass will not resolve until the sixth month after radiation.

Abstract
CT scans of the nasopharynx and the base of skull were performed in 54 patients with histologically proven NPC. The CT findings are compared to those obtained by routine clinical examination. In this series, involvement of the parapharyngeal spaces was found by CT scan in 61% (33/54) of patients, which is impossible to assess by clinical means. Intracranial invasion was demonstrated by CT scan with intravenous contrast enhancement in five patients. CT is more sensitive in showing the erosion of skull base than X ray film. CT scans demonstrated 17% (5/30) of bony invasion in X ray negative patients. Clinical examination showed one involved wall in nine patients; CT scan discovered involvement of two or more walls in five (55%) of these nine. Routine clinical examination discovered extra-nasopharyngeal extensions in 34 locations, whereas CT scans discovered 106, a ratio of 1:3.1. The common sites of extra-nasopharyngeal extension detected by CT scan are: parapharyngeal space, intracranial invasion, sphenoidal sinus, orbit, ethmoidal sinus, maxillary antrum, oropharynx and the nasal cavity. In T-staging of NPC, 55% (6/11) of clinical T2 lesions are up-staged by CT. Thirty-six percent (4/11) of clinical T3 lesions were also up-staged. However, 94% (17/18) of clinical T4 lesions remained unchanged. Only 6% (1/18) of clinical T4 lesions were down-staged.
