We have conducted a two-color visible-ultraviolet （VIS-UV） resonance-enhanced laser pho- toionization and pulsed field ionization-photoelectron （PFI-PE） study of gaseous vana- dium mononitride （VN） in the total energy range of 56900-59020 cm-1. The VN molecules were selectively excited to single rotational levels of the intermediate VN（D3H0, v＇=0） state by using a VIS dye laser prior to photoionization by employing a UV laser. This two-color scheme allows the measurements of rovibronically selected and re- solved PFI-PE spectra for the VN＋（X2A; v＋=0, 1, and 2） ion vibrational bands. By simulating the rotationally resolved PFI-PE spectra, J＋=3/2 is determined to be the lowest rotational level of the ground electronic state, indicating that the symmetry of the ground VN＋ electronic state is 2A3/2. The analysis of the PFI-PE spectra for VN＋ also yields accurate values for the adiabatic ionization energy for the formation of VN＋（X2A3/2）, IE（VN）=56909.5＋0.8 cm-1 （7.05588±0.00010 eV）, the vibrational fre- quency wc＋=1068.0±0.8 cm-1, the anharmonicity constant wc＋Xe＋=5.8±0.8 cm-1, the rotational constants Be＋=0.6563±0.0005 cm-1 and ae＋=0.0069±0.0004 cm-1, and the equi-librium bond length, re＋=1.529A, for VN＋（X2A3/2）; along with the rotational constants Bc＋=0.6578i0.0028 cm-1 and a＋=0.0085±0.0028 cm-1, and the equilibrium bond length re＋=1.527A for VN＋（X2As/2）, and the spin-orbit coupling constant A=153.3±0.8 cm-1 for VN＋（X2/k5/2,3/2）. The highly precise energetic and spectroscopic data obtained in the present study are valuable for benchmarking the predictions based on state-of-the-art ab initio quantum calculations.

Background Obesity is a common risk factor for several diseases. Obesity related hormone and increased insulin resistance （IR） may contribute to the effects of obstructive sleep apnoea on cardiovascular consequences. We investigated ghrelin and IR in non-diabetic apnoeic patients with stable coronary heart disease and assessed the effects of continuous positive airway pressure （CPAP）. Methods Plasma ghrelin, glucose and insulin were measured in 22 patients with CPAP and 22 matched controls without CPAP at baseline and three months. Indexes including homeostasis model assessment IR （HOMA IR）, HOMA S and HOMA β were calculated for the assessment of IR, insulin sensitivity and pancreatic β cell function. Results At three months follow-up, plasma ghrelin levels and HOMA IR in CPAP group were significantly decreased （P=0.002 and 0.046, respectively） while those in control group increased significantly （P=0.012 and 0.009, respectively）. Significant moderate correlations were found between ghrelin vs. HOMA IR and ghrelin vs. HOMA S after CPAP, however, for those without CPAP, no significant associations were observed. Conclusions Short-term effective continuous positive airway pressure had a significant effect on lowering plasma ghrelin levels and IR, but not body fat. Further large scale and longer term studies are warranted to corroborate these findings.

AIM： To clarify the expression change of Wnt-induced secreted protein-1 （WISP-l） in human rectal cancer and to determine whether it is correlated with invasion and metastasis of human rectal cancer.METHODS： Eighty-six paired samples of rectal cancer and surgically resected distant normal rectal tissue were collected and allocated into cancer group and control group respectively. WISP-1 mRNA was detected by relative quantitative real-time RT-PCR and WISP-1 protein was examined by immunohistochemical staining.RESULTS： WISP-1 gene overexpression was found in 65% （56/86） primary rectal cancers, 2-30 times that of the level in normal matched rectal tissues （P = 0.001）. The mRNA expression level was correlated with Duke＇s staging, histological differentiation grade and lymph node status. The WISP-1 protein expression was in accordance with mRNA expression level. The positive degree of immunohistochemical staining in the cancer group （1.40±0.35） was different from that in control group （1.04± 0.08, P 〈 0.001）. Moreover, in cancer group the positive staining degree in high-level mRNA cancers （1.46 ±0.37, n = 56） was higher than that in low-level mRNA （1.28 ± 0.28, n = 30, P = 0.018）.CONCLUSION： Aberrant levels of WISP-1 expression may play a role in rectal tumorigenesis. WISP-1 may be used as a specific clinical diagnosis and prognosis marker in rectal cancer.

BACKGROUND: The treatment for primary tumor in the caudate lobe of the liver is difficult because of its unique anatomical location. This study was undertaken to improve operative techniques and results by a new anatomical method of caudate lobectomy. METHODS: Clinical data of 16 patients who had had caudate lobectomy for the liver from January 1996 to November 2004 were retrospectively analyzed. The third porta hepatis anatomical method was performed in all 16 patients. Operative time, intraoperative blood loss, postoperative complications were recorded. The 1-, 3-, and 5-year survival rates of 13 patients with caudate lobe carcinoma were followed up. Anatomical status, operative routes, operative procedures, liver blood supply were evaluated. RESULTS: The operation was successful in the 16 patients. The operative time was 255±70 minutes and blood loss 740±402 ml. None of the patients died from massive bleeding during the operation, nor did complications such as biliary fistula and liver failure occurred. In 13 patients with malignant tumor, 7 died from recurrence and metastasis of the tumor and the other 6 are still alive at the end of follow-up. One patient has survived for 6 years. The 1-, 3-, and 5-year survival rates in the 13 patients were 83.9%, 58.7% and 39.2%, respectively. CONCLUSION: Caudate lobectomy by the third porta hepatis anatomical method can improve operative effect and increase the resection probability for solitary tumor in the caudate lobe.

提出废旧镍氢(Ni-MH)电池全金属可持续回收的方法,分别用硫酸钠溶液电解获得的H_(2)SO_(4)和NaOH溶液作为浸出剂和沉淀试剂。电极材料在温和条件下浸出,超过99%的稀土元素在pH1.0时以双硫酸盐的形式从溶液中沉淀,进而通过与NaOH反应转化为氢氧化物。在后续浸出液的纯化过程中,Al^(3+)和Fe^(3+)在pH 5.5时沉积,Zn^(2+)和Mn^(2+)用皂化D2EHPA-煤油从浸出液中萃取出来,形成两种具有工业价值的氢氧化物副产品。Ni^(2+)和Co^(2+)在pH9.5时沉淀,总回收率为97.5%。Na_(2)SO_(4)的总回收率达97%。这种金属回收方法可带来明显的经济效益,且闭环处理过程中无固体或液体废弃物。

Aim: To explore the connection between Hoxa-10 and humanimplantation by observing the expression pattern of Hoxa-10 in hu-man endometrium during normal menstrual cycle. Methods:Human Hoxa-10 Riboprobe was prepared and the expression ofhomeobox gene Hoxa-10 in the human endometrium during men-strual cycle was determined through in situ hybridization. Re-sults: Hoxa-10 expressed in both glandular cells and stromalcells at proliferative phase and early secretory phase. But the ex-pression of Hoxa-10 was markedly decreased or disappeared inglandular epithelium at the mid secretory phase, which correspondsto the time of implantation, and at late secretory phase. Conclu-sion; The results suggest that Hoxa-10 may play an essential rolein establishing necessary conditions for implantation. (Reprod Con-tracep 2001; 21: 149-52)

The influence of Nb-V microalloying on the hot deformation behavior and microstructures of medium Mn steel(MMS)was investigated by uniaxial hot compression *** establishing the constitutive equations for simulating the measured flow curves,we successfully constructed deformation activation energy(Q)maps and processing maps for identifying the region of flow *** concluded the following consequences of Nb-V alloying for MMS.(i)The critical strain increases and the increment diminishes with the increasing deformation temperature,suggesting that NbC precipitates more efficiently retard dynamic recrystallization(DRX)in MMS compared with solute Nb.(ii)The deformation activation energy of MMS is significantly increased and even higher than that of some reported high Mn steels,suggesting that its ability to retard DRX is greater than that of the high Mn content.(iii)The hot workability of MMS is improved by narrowing the hot processing window for the unstable flow stress,in which fine recrystallized and coarse unrecrystallized grains are present.
