[Impacts of rotating or lifting-thrusting manipulation on distant vision of naked eye in patients of juvenile myopia: a randomized controlled trial].

Objective: To compare the differences in the efficacy on distant version of naked eye in the patients of juvenile myopia between rotating manipulation and lifting-thrusting manipulation of acupuncture.

Methods: One hundred and twenty cases (240 eyes) were randomized into a rotating manipulation group and a lifting-thrusting manipulation group, 60 cases (120 eyes) in each group. Additionally, a corrective lenses group, 60 cases (120 eyes), was set up as the control.

[Clinical observation on strong stimulation of acupoints around eyes for treatment of adolescent myopia].

Objective: To observe the therapeutic effect and influential factors of strong stimulation of acupoints around eyes by reducing method of twisting the needle for treatment of adolescent myopia, and to compare the different curative effects of both weak and strong stimulus intensities and wearing glasses in daytime.

Methods: According to the principle of knowing and permission, the patients were divided into a strong stimulation group (60 cases, 120 eyes), a weak stimulation group (60 cases, 120 eyes) and a wearing glasses group (60 cases, 120 eyes). Both the strong stimulation group and the weak stimulation group were treated by reducing method of twisting the needle, with Cuanzhu (BL 2), Yuyao (EX-HN 4), Sizhukong (TE 23), Sibai (ST 2) and Taiyang (EX-HN 5) selected.

Assembly of helical hydrogen bonds in a new layered aluminophosphate [C6N3H17][Al2(HPO4)(PO4)2].

A new layered aluminophosphate, [C6N3H17][Al2(HPO4)(PO4)2] (denoted AlPO-CJ21), has been prepared in an alcoholic system by the use of N-(2-aminoethyl)-piperazine (AEPP) as the template. Its inorganic layer containing a series of bridged six-membered rings (MRs) is a new type of 4.6-net sheet built up from AlO4, PO2(OH)(=O), and PO3(=O) tetrahedra.

Tetraaqua(2,2'-bipyridine)nickel(II) terephthalate.

The reaction of nickel(II) nitrate with terephthalic acid and 2,2'-bipyridine in dimethylformamide solution gives the title complex, [Ni(C(10)H(8)N(2))(H(2)O)(4)](C(8)H(4)O(4)). The Ni(II) ion is octahedrally coordinated to one 2,2'-bipyridine and four water molecules and does not coordinate to the terephthalate anion. Hydrogen bonds between the terephthalate anions and the [Ni(2,2'-bipy)(H(2)O)(4)](2+) cations produce a two-dimensional hydrogen-bonding architecture with double sheets.
