OBJECTIVETo explore protective effects of acupuncture at "Zusanli" (ST 36) on cerebral tissue in rats with sepsis.

METHODSCecal ligation and puncture (CLP) was applied to duplicate the rat model of sepsis. According to random number table, thirty SD rats were divided into a sepsis model group (group A), a sepsis model plus electroacupuncture (EA) group (group B), and a sepsis model plus non-acupoint EA group (group C), ten rats in each one. EA with the same frequency and intensity at "Zusanli" (ST 36) and non-acupoint (0.5 cm laterally to "Zusanli") for 30 min was applied in the group B and group C, respectively. No treatment was given in the goup A. 6 hours after CLP, blood was acquired from abdominal aorta to measure the levels of neuron specific enolase (NSE). Then the rats were sacrificed by abdominal aorta exsanguination to take their cerebral tissue for measuring the levels of tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6).

RESULTSSix hours after CLP, the level of NSE was (3.51 +/- 0.39) ng/mL in group B, which was significantly lower than (7.72 +/- 0.64) ng/mL in group A (P<0.05). The level of NSE was (8.02 +/- 0.72) ng/mL in the group C, which had no statistical significance with group A (P>0.05). The levels of TNF-alpha, IL-6 in cerebral tissue in group B were significantly lower than that of group A and C (all P>0.05).

CONCLUSIONEA at "Zusanli" (ST 36) has certain protective effect on septic rat's brain, which has some relationship with decreasing levels of cerebral tissue proinflammatory cytokine and plasma NSE. EA at non-acupoint has no the same action.

AlM: To observe the therapeutic effects of improved external dacryocystorhinostomy.
METHODS:Retrospective analysis on 94 patients with monocular chronic dacryocystitis in our hospital from October 2010 to December 2013 were taken the improved external dacryocystorhinostomy. The improved surgery which was based on the traditional surgery including: 1. Nasal packing after anesthesia to relieve the pain and bleeding; 2. Not cut the medial palpebral ligament; 3. Suture the upper membrane of the nasal mucosa only;4. Pipe placement;5. Skin layered hairdressing suture. The patients were follow-up 3mo-2a after operation.
RESULTS: Ninety-three cases of patients cured with completely asymptomatic, no epiphora or mucopurulent secretion flow out from the lacrimal punctum, unobstructed lacrimal irrigation, the efficiency is 99%, 1 case of patient was epiphora, obstructed lacrimal irrigation, 1% was invalid.
CONCLUSlON:The improved external dacryocystorhinostomy is an effective surgical method which is easy to operate with high cure rate and its long term effect is precise.

This study was aimed to establish the quality and quantity analysis methods of tectoridin contented in the Iris tectorum Maxim. Thin layer chromatography (TLC) method was used to give quality analysis on tectoridin in I. tectorum. And the HPLC method was used to give quantity analysis on tectoridin in I. tectorum. The Diamonsil C18 (200 mm í 4.6 mm, 5 μm) column was used as analytical column. The acetonitrile-0.2% phosphoric acid (20:80) was used as mobile phase at the flow rate of 1.0 mL·min-1.
