OBJECTIVETo study whether the dose of controlling antihypertensive drug is reduced by transcutaneous electrical acupoint stimulation (TEAS) and the anesthetics, as well as the control of blood pressure (BP) and heart rate (HR) in endoscopic endonasal surgery with general anesthesia.

METHODSSixty patients for selective endoscopic endonasal surgery with general anesthetics and controlling antihypertension involved were selected and randomized into a TEAS group, a sham-TEAS group, 30 cases in each one. The electric pads were attached to bilateral Hegu (LI 4), Zusanli (ST 36), Sanyinjiao (SP 6) and Quchi (LI 11), stimulated with Hans-200 apparatus, 3 to 5 mA, 2 Hz/100 Hz in the TEAS group based on the patients' response to comfort. No electric stimulation was applied to the sham-TEAS group. The general anesthesia started after 30 min intervention and lasted till the end of surgery. The BP and HR were observed and recorded at the end of monitoring in operation room, 10 min after tranquilization (T0), 30 min after intervention (Tj, after induction~of general anestiesa (T2), 30 min after surgery start (T3), 60 min after surgery start (T4) and 30 min after extubation (T5). The doses of vecuronium bromide, propofol and nitroglycerin were recorded statistically in surgery, as well as the operative bleeding volume, the operative time, the resuscitation time and the visual analogue scale (VAS) score after resuscitation.

RESULTSCompared with that at T0, the mean arterial pressure (MAP) at T2, T3, T4 and T5 in the TEAS group and at T3 and T4 in the sham-TEAS group was all reduced, indicating the significant difference (all P < 0.01). MAP at T2 and T5 in the TEAS group was lower than that in the sham-TEAS group (both P < 0.01). Compared, with that at T5, except at T2 in the TEAS group (P<0. 05), HR was not different significantly at the rest time points (all P > 0.05). HR was different at T2 to Ts in the sham-TEAS group statistically (all P < 0.01). The doses of vecuronium bromide, propofol and nitroglycerin, the operative bleeding volume, the operative time, the resuscitation time and VAS after resuscitation were not different significantly between the two groups (all P > 0.05).

CONCLUSIONThe general anesthesia with TEAS and anesthetics involved for controlling antihypertension contributes to the control of BP and HR in the patients in endoscopic endonasal surgery. The impacts are not obvious on the doses of antihypertensive drug, the general anesthetics, the operative bleeding volume, the time of resuscitation and the postoperative analgesia.

Objective To study the ameliorative effects of pseudoginsenoside GQ (PGQ) on electrocardiogram changes in rats with acute myocardial ischemia induced by isoproterenol (ISO). Methods 50 Wistar rats were divided into five groups (n=10) randomly. Group I : i. v. 0.9% sodium chloride water liquor; Group II : i. v. verapamil hydrochloride of 0. 2 mg ? kg-1 ; Group III : i. v. 3. 0 mg ? kg-1 of PGQ; Group IV : i. v. 6. 0 mg ? kg-1 of PGQ; Group V : i. v. 12. 0 mg ? kg-1 of PGQ. Myocardial ischemia was induced by intravenous injection of ISO (2.0 mg ? kg-1). ST-segment changes in the lead II , precordial in lead V1 and precordial in lead V2 were examined. Results In lead II , lead precordial V 1 and lead precordial V 2 , ST-segment elevation of three PGQ groups were not obvious at every time point, the extents of ST-segment elevation were lower than those in sodium chloride water liquor group (P

Four compounds were isolated from the fruit of Panax quinquefolius L. , They were iden-tified as 20 (R)-ginsenoside-Rg3( Ⅲ ), ginsenoside-Ra1( Ⅱ ), pseudo ginsenoside-RTs (iⅣ) and a new com-pound named quinquetriose ( Ⅰ ). Its structure was established as β3-D-xylopyranosyl-(1→6)-α-D-glucopy-ranosyl (1→6)-β-D-glucopyranoside, on the basis of chemical and spectroscopic evidences.

Abstract?AIM: To observe the clinical efficacy of intravitreal Lucentis injection combined with panretinal photocoagulation ( PPR ) and compound trabeculectomy for neovascular glaucoma ( NVG) .?METHODS:A total of 14 cases (14 eyes) with NVG were collected from January to November 2015.All cases were treated with intravitreal lucentis injection, PPR and compound trabeculectomy by turns.Intraocular pressure ( IOP) , visual acuity and the complications at pre-or post-surgery were recorded, respectively.?RESULTS: Followed up for 3-6mo, the average IOP preoperatively was significantly decreased than that detected at post-operation ( 18.00 ±6.70 vs 41.65 ± 4.07mmHg, t=11.288, P<0.05).IOP less than 21mmHg with or without the usage of anti-intraocular pressure drugs was defined as the sign of successful or effective surgery, respectively.At the ultimate follow-up, 11 cases were successful, 2 cases were effective, and the success rate was 79%, effective rate was 14%.Only 1 case was applied cyclocryotherapy due to the uncontrolled IOP. Moreover, the results of visual acuity detection demonstrated that 6 eyes got a better visual acuity, 7 eyes remained the same condition and 1 case got no light perception. Meanwhile, 13 cases showed none iris neovascularization during the follow-up; 1 case got a reappearance of iris neovascularization on the third month, which was then dissolved subjected to the intravitreal lucentis injection in combination with PPR. One case developed post -operative hyphema and absorbed after 1wk. No shallow anterior chamber and eyeball atrophy happened.?CONCLUSION:Intravitreal lucentis injection combined with PPR and compound trabeculectomy is an effective and safe therapeutic strategy for the treatment of NVG.
