Shi-Style Cervical Mobilizations Versus Massage for Cervical Vertigo: A Multicenter, Randomized, Controlled Clinical Trial.

Large sample and high-quality evidence to evaluate the preliminary safety of the mobilizations and massage for cervical vertigo are not yet available. Thus, the present study aimed to investigate the comparative effectiveness and preliminary safety of Shi-style cervical mobilizations (SCM) compared with traditional massage (TM) in cervical vertigo patients. A prospective, multicenter, open-label, randomized, controlled clinical trial with a 1:1 allocation ratio.

Comparison of clinical outcomes and postoperative quality of life after surgical treatment of type II submucous myoma via laparoscopy or hysteroscopy.

Objective: This study was performed to compare the clinical outcomes, advantages, and disadvantages of laparoscopic myomectomy (LM) and transcervical resection of myoma (TCRM) in the treatment of type II submucous myoma.

Methods: In total, 136 patients with type II submucous myoma with a tumour diameter of 4 to 5 cm were randomly assigned to the hysteroscopy group or laparoscopy group.

Results: The operative duration was shorter and the intraoperative bleeding volume was lower in the hysteroscopy than laparoscopy group.

Shi-style cervical manipulations for cervical radiculopathy: A multicenter randomized-controlled clinical trial.

Background: There is a lack of high-quality evidence supporting the use of manipulation therapy for patients with cervical radiculopathy (CR). This study aimed to evaluate the effectiveness of Shi-style cervical manipulations (SCMs) versus mechanical cervical traction (MCT) for CR.

Methods: This was a randomized, open-label, controlled trial carried out at 5 hospitals in patients with CR for at least 2 weeks and neck pain.

Structures and aromaticity of X(2)Y(2)(-) (X = C, Si, Ge and Y = N, P, As) anions.

The equilibrium geometries, total energies, and vibrational frequencies of anions X(2)Y(2)(-) (X = C, Si, Ge and Y = N, P, As) are theoretically investigated with density functional theory (DFT) method. Our calculation shows that for C(2)N(2)(-) species, the D(2h) isomer is the most stable four-membered structure, and for other species the C(2v) isomer in which two X atoms are contrapuntal is the most stable structure at the B3LYP/6-311 +G(*) level. Wiberg bond index (WBI) and negative nucleus-independent chemical shift (NICS) value indicate the existence of delocalization in stable X(2)Y(2)(-) structures.
