[Acupuncture combined with tuina therapy for stiff neck with levator scapula injury type: a randomized controlled trial].

OBJECTIVE: To observe the clinical efficacy of acupuncture combined with tuina therapy for stiff neck with levator scapula injury type. METHODS: A total of 162 patients with stiff neck of levator scapula injury type were randomly divided into an acupuncture combined with tuina group (combined group, 52 patients), a tuina group (55 patients), and an acupuncture group (55 patients). The patients in the acupuncture group received acupuncture on the affected side's Houxi (SI 3), inserting the needle 10 to 20 mm towards Laogong (PC 8) with strong or moderate stimulation, and patients were instructed to move their neck, shoulders, and upper limbs during the process, with the needle retained for 2 to 3 min. The patients in the tuina group received strong stimulation pressing on tender points to release the starting and ending points of the trapezius muscle with modified techniques. The combined group first received tuina therapy, followed immediately by acupuncture treatment at the Houxi (SI 3). Treatments were administered every other day for a total of three sessions. Before treatment and on 1, 3, and 7 days after treatment, the simple McGill pain questionnaire (SF-MPQ) scores [including the pain rating index (PRI), visual analogue scale (VAS), and present pain intensity (PPI) scores] of the head, neck and shoulder, cervical spine mobility scores were observed, and the clinical efficacy and safety of each group were evaluated. RESULTS: On the 1, 3, and 7 days after treatment, the SF-MPQ, PRI, VAS, and PPI scores of the head, neck, and shoulder in all groups were significantly reduced (P<0.01). On the 1 and 3 days after treatment, the above scores in the combined group were lower than those in the tuina group and the acupuncture group (P<0.05, P<0.01). On the 7 days after treatment, the above scores in the combined group were lower than those in the acupuncture group (P<0.01). On the 3 days after treatment, the SF-MPQ, PRI, and VAS scores in the tuina group were lower than those in the acupuncture group (P<0.01). On the 7 days after treatment, the SF-MPQ, PRI, VAS, and PPI scores in the tuina group were lower than those in the acupuncture group (P<0.01, P<0.05). On the 1, 3, and 7 days after treatment, the cervical spine mobility scores in each group were decreased compared to those before treatment (P<0.01). On the 3 days after treatment, the cervical spine mobility score in the combined group was lower than that in the acupuncture group and the tuina group (P<0.01). On the 1, 3, and 7 days after treatment, the cured rate in the combined group was higher than that in the tuina group and the acupuncture group (P<0.01). During the treatment period, no serious adverse reactions occurred in any group. CONCLUSION: Acupuncture combined with tuina therapy could effectively improve stiff neck with levator scapula injury type, alleviate patient pain, restore cervical spine mobility, and clinically outperform both tuina and acupuncture therapy alone.

Isolation and characterization of two glutathione S-transferases from freshwater bivalve Anodonta woodiana: Chronic effects of pentachlorophenol on gene expression profiles.

Glutathione S-transferases (GST) play a prominent role in protecting cells against oxidative stress. Our previous study showed that the reactive oxygen species (ROS) generated from pentachlorophenol (PCP) could cause an acute impact on freshwater bivalve Anodonta Woodiana, but its chronic toxicity remain unclear. In order to investigate the chronic effect of PCP, clams A. Woodiana were randomly grouped into PCP treated group in which animals were administrated with 13.9 µg/L concentrations of PCP, and control group those with similar volume dimethyl sulfoxide. In addition, two complete GST sequences were isolated from A. Woodianaa and respectively named AwGST1 and AwGST2. The full-length cDNA of AwGST1 was consisted of a 5' untranslated region (UTR) of 132 bp, a 3' UTR of 80 bp and an open reading frame (ORF) of 609 bp encoding a polypeptide of 203 amino acids. The full-length cDNA of AwGST2 contained a 5' UTR of 57 bp, a 3' UTR of 291 bp and an ORF of 678 bp encoding a polypeptide of 226 amino acids. The constitutive expression levels of AwGST1 and AwGST2 were examined in different tissues including foot, mantle, adductor muscle, heart, hepatopancreas, hemocytes and gill. Administration of PCP could result in a significant increase of AwGST1 and AwGST2 expression in the hepatopancreas, gill and hemocytes. In the hepatopancreas, AwGST1 mRNA levels of PCP treated group increased more than 28.73% at day 1, then 70.37% (P < 0.05) at day 3, reach to 6.64 times (P < 0.01) at day 15 in contrasted with that of control group. AwGST2 increased more 18.18%, 82.88% (P < 0.05) and 2.43 times (P < 0.01) at day 1, 3 and 15, respectively. In the gill, AwGST1 expression showed a significant up-regulation in the PCP treated group during experiment observed compared with that of control group, mRNA level of AwGST2 increased more than 1.44 times (P < 0.05). In addition, expressions of AwGST1 and AwGST2 were significantly induced after PCP treatment in the hemocytes. These results indicated that up-regulations of AwGST1 and AwGST2 expression in bivalve A. woodiana are contribute to against oxidative stress derived from PCP treatment during experiment observed.
