We report a rare case of pleomorphic adenoma arising from the nasal septum. A 37-year-old woman presented with a 1-year-history of right-sided occasional epistaxis. Computed tomographic scans revealed an oval mass in the right nasal cavity. The tumor was removed endoscopically with endonasal approach. The microscopic finding showed numbers of myoepithelial cells and duct-like structures consisting of loose myxoid stroma. This lesion had histological characteristics of a pleomorphic adenoma, and this was confirmed by immunohistochemical expression of cytokeratin, S-100 protein and SMA. Her post-operative course was uneventful, and she is currently free from the disease 1.5 years after surgery.

OBJECTIVETo compare the differences in the clinical efficacy on post-stroke upper limb spasmodio hemiplegia among the combined therapy of relaxing needling (Huici) technique combined with wheat-grain moxibustion, simple relaxing needling and conventional acupuncture.

METHODSNinety patients were-randomized into a group with the combined therapy of relaxing needling technique combined with wheat-grain moxibustion (a combined therapy group), a simple relaxing needling group and a conventional acupuncture group, 30 cases in each group. In the combined therapy group, the relaxing needling technique was used in combination with wheat-grain moxibustion. The relaxing needling technique was applied to Jianyu (LI 15), Quchi (LI 11), Shousanli (LI 10), etc. The wheat-grain moxibustion was applied to Qihai (CV 6), Guanyuan (CV 4), Mingmen (GV 4), etc. In thel simple relaxing needling group, the relaxing needling technique was used simply. In the conventional acupuncture group, the conventional lifting, thrusting and rotating technique with filiform needle was adopted at the same acupoints as the simple relaxing needling group. The treatment was given once every day; 6 treatments made one session. Totally 4 sessions were required, with 1 day at intervals. The modified Ashworth scale (MAS), Fugl-Meyer assessment (FMA) and Barthel index (BD were adopted to assess the upper limb muscle tension, motor functioni and daily life activity.

RESULTSAfter treatment, MAS score was all reduced as compared with that before treatment in each group, and FMA score and BI score were increased as compared with those before treatment (all P<0.01). MAS score in the combined therapy group was lower than that in either the simple relaxing needling group or the conventional acupuncture group (both P<0.01), and the score in the simple relaxing needling group was lower than that in the conventional acupuncture group (P<0.05). FMA score and BI score in the combined therapy group were higher than those in the simple relaxing needling group and the conventional acupuncture group (both P<0.01). FMA score in the simple relaxing needleing group was higher than that the Enventional acupuncture group (P<0.05). The total effective rate in the combined therapy group was 93.3% (28/30), higher; than 86.7% (26/30) in the simple relaxing needling group (P<0.01), and 83.8% (25/30) in the conventionaP acupuncture group (P<0.01).

CONCLUSIONThe combined therapy of relaxing needling technique and wheat-grain moxibustion achieves more satisfactory efficacy on post-stroke upper limb spasmodic hemiplegia compared with the simple relaxing needling and conventional acupuncture.

The EP model rats exhibited a significant decrease in the concentration of endogenous antioxidants (CAT, GSH, SOD, GR and T-AOC), while an increase of the concentration of MDA and phosphorylation p38 protein as compared to sham group (P<0.05) . After treatment of the Gas,treatment group rats attenuated the seizure degree,exhibited a significant increase of the concentration of endogenous antioxidants (P<0.05),while a decrease in concentration of MDA and phosphorylation of p38 as compared to model group (P<0.05) . Conclusion Gas may have a neuroprotective role in central nervous system of epileptic rats modle by down-regulateing the seizure degree and the activity of p38 kinase and up-regulateing the content of endogenous antioxidants.

Objective To evaluate the efficacy of multimodal-antiemetic therapy on postoperative dizziness,headache,nausea and vomiting (PONV) in patients undergoing thyroidectomy.Methods One hundred patients (39 males and 61 females,ASA physical status Ⅰ or Ⅱ) scheduled for thyroidectomy were randomly divided into two groups according to random number table: control group (group C) and multimodal-antiemetic therapy group (group M).Two groups received total intravenous anesthesia (TIVA) with propofol and remifentanil.Prophylactic dexamethasone 10 mg were given after anesthesia induction and palonosetron hydrochloride 0.25 mg was used 30 min before the end of surgery in both groups.Mannitol 2 ml/kg in group M and the same amount of normal saline in group C were given 30 min before the end of surgery.The incidence of dizziness,headache and PONV were observed for 24 h in two groups.Results The incidence of headache was 5 cases (10%)and PONV was 5 cases (10%) in group M,which were respectively significantly lower than that of group C of 15 cases (30%) and 12 cases (24%) in 24 h after surgery (P<0.05).The additional antiemetic therapy for 24 h after surgery in group M of 2 cases (4%) was significantly lower than that of group C of 9 cases (18%) (P<0.05).Conclusion The multimodal-antiemetic therapy: prophylactic dexamethasone,palonosetron hydrochloride and mannitol were used 30 min before the end of surgery could significantly reduce the incidence of dizziness,headache and PONV after thyroidectomy.

OBJECTIVETo explore the protective mechanism of electroacupuncture (EA) at "Neiguan" (PC 6) on ischemic myocardial injury, and to explain the response patterns and characteristics of the specific effect of acupoints along meridians in sodium channel in the level of cardiac organ.

METHODSA total of 60 SPF male rats were randomly divided into a blank group, a model group, a non-acupoint group, a Neiguan group and a Lieque group, 12 cases in each one. Except the blank group, rats in the remaining group were treated with subcutaneous injection of isoprenaline to establish the model of myocardial ischemia. Rats in the Neiguan group, Lieque group and non- acupoint group were treated with EA, dilatational wave, with a frequency of 2 Hz/20 Hz. The intensity was 2-3 mA. The needles were retained for 20 min per time, once a day for consecutive 7 days. In the blank group and control group, the rats were grasped and fixed at the treating time each day. The western-blot method was used to test the expression of voltage-gated sodium channel alpha subunit (Nav 1.5), protein tyrosine kinase (PTKs) and protein tyrosine phosphatase (PTPs).

RESULTSThe expression of Nav 1.5 and PTKs in the model group was lower than that in the blank group (both P<0. 01); the expression in the Neiguan group and Lieque group was higher than that in the model group (all P < 0.01); the expression of Nav 1.5 and PTKs in the Neiguan group was higher than that in the Lieque group (both P < 0.01). The expression of PTPs in the model group and non-acupoint group was higher than that in the blank group (both P < 0.01); the expression of PTPs in the Neiguan group and Lieque group was significantly down-regulated, which was lower than the model group (both P < 0.01); the down-regulation in the Neiguan group was significantly different from that in the Lieque group (P < 0.05).

CONCLUSIONEA at "Neiguan" (PC 6), by down-regulating the expression of PTPs, up-regulating the expression of Nav 1.5 and PTKs, is likely to achieve the aim of regulation on sodium channel activity and calcium overload, further to improve myocardial ischemia, which provides experimental basis for the theory of the specific effect of acupoints along meridians.
