"Three-in-One" Structural-Building-Mode-Based Ti-Type Titanium Oxo Cluster Entirely Protected by the Ligands Benzoate and Salicylhydroxamate.

Titanium oxo clusters (TOCs) with accurate molecular structures have potential applications in photocatalysis, such as photocatalytic degradation, hydrogen production, and water oxidation. The hydrolytic stability and light absorption ability of TOCs have important impacts on photocatalysis, where the selection of peripheral organic ligands plays a significant role. In this regard, salicylhydroxamic acid (abbreviated as HL) attracts our attention, acting as a ligand for its multidentate and dye-functional features, which can increase the hydrolytic stability and broaden light absorption for TOCs.

The microstructures and mechanical properties of nanocrystalline LiSiO: molecular dynamics simulations.

The microstructures and mechanical properties of nanocrystalline LiSiO have been investigated molecular dynamics calculations. The results indicate that the mean atomic mass densities of nanostructured LiSiO with different mean grain size are slightly lower than that of ordinary crystal LiSiO. Interestingly, a significant anti-Hall-Petch effect between yield stress and average grain size is observed in the tensile deformation simulation of the samples.

Syntheses, crystal-solution structures and magnetic properties of a series of decanuclear heterometallic [LnCoCo] (Ln = Eu, Gd, Tb, Dy) clusters.

Four unprecedented decanuclear heterometallic [Ln2CoII4CoIII4] clusters based on a diethanolamine ligand (H2dea), namely [Eu2CoII4CoIII4(dea)8(HCOO)4(OH)2(Cl)2(CH3OH)2]Cl2·4CH3OH·2H2O (1), [Gd2CoII4CoIII4(dea)8(HCOO)4(OH)2(Cl)2(CH3OH)2]Cl2·4CH3OH·2H2O (2), [Tb2CoII4CoIII4(dea)8(HCOO)4(OH)2(Cl)2(CH3OH)2]Cl2·2CH3OH·4H2O (3) and [Dy2CoII4CoIII4(dea)8(HCOO)4(OH)2(Cl)2(CH3OH)2]Cl2·2CH3OH·4H2O (4) were synthesized through a facile solution method. Single-crystal X-ray diffraction analyses reveal that complexes 1-4 consist of a [Ln2CoII4CoIII4] core, which is constructed by bridging a quasi-double cuboidal [Ln2CoII2CoIII2] core with two [CoIICoIII] units. Electrospray ionization mass spectrometry (ESI-MS) using methanol solution reveals that complexes 1-4 are stable in the solution, and the clusters undergo three different substitution reactions (Cl- replaced by OH-, OH- replaced by CH3O- and HCOO- replaced by OH-/CH3O-) at the same time in the ionization state.

[Effect of stiletto needle intervention combined with massage on dysfunction and pain of knee-joints in patients with knee osteoarthrosis].

Objective: To observe the effectiveness of stiletto needle stimulation combined with massage in the treatment of dysfunction and pain of knee joints in knee osteoarthrosis (KOA) patients.

Methods: One hundred KOA outpatients and inpatients were randomly and equally divided into treatment and control groups. Patients of the treatment group were treated by using stiletto needle stimulation of 5-10 tender-points (at the medial collateral ligament, internal condyle of femur, medial condyle of femur, etc.

[Treatment of lumbar disc herniation combine with buttock tender node with Pizhen].

Objective: To observe the therapeutic effects of Pizhen in treating lumbar disc herniation combined with buttock tender node.

Methods: From August 2009 to February 2010,83 patients (29 males and 54 females) with lumbar disc herniation combined with buttock tender node were randomly divided into the Pizhen group and acupuncture group. Pizhen group were treated with Pizhen manipulation, inserting needle by vertical prick with quacking inserting and quick withdrawing the needle, no rotating and the depth was through the surface of fascia, two times as a course of treatment; acupuncture group were treated with acupuncture, inserting Ashi-point, retaining the needle 20 min, ten times as a course of treatment.

[Effect of Chinese medicinal massage on endocrinal function in women with climacteric syndrome].

Objective: To explore the therapeutic effect of Chinese medicinal massage with nourishing-Shen and activating-blood manipulation in treating women with climacteric syndrome and its influence on endocrinal function.

Methods: Sixty patients were assigned to two groups, the 40 patients in the treated group were treated by Chinese medicinal massage for 20 min once every other day; the 20 patients in the control group were treated by hormone replacement therapy with Premarin 0.625 g, once daily by oral taking.

Risk factors for HPV infection and cervical cancer among unscreened women in a high-risk rural area of China.

We report a prevalence rate of 23.6% human papillomavirus (HPV) infection with oncogenic subtypes and 2.4% cervical intraepithelial neoplasia (CIN) III and cervical cancer (CC) in rural middle-aged women in 2 counties with the highest CC mortality in Shanxi Province, China.

[Population-based study of human papillomavirus infection in high-risk area for cervical cancer in Shanxi Province, China].

Objectives: To investigate the prevalence of oncogenic type of human papillomavirus (HPV) infection and identify the high risk population for conducting immuno/chemoprevention of cervical cancer.

Methods: All married women aged 30 to 50 with no history of hysterectomy, pelvic radiation and non-pregnant from certain villages of Xiangyuan and Yangcheng County were invited. This study was conducted through two phases.
