The clinical analgesic effect of electro-acupuncture (EA) stimulation (EAS) on breakthrough pain induced by remifentanil in patients undergoing radical thoracic esophagectomy, and the mechanisms were assessed. Sixty patients (ASAIII) scheduled for elective radical esophagectomy were randomized into three groups: group A (control) receiving a general anesthesia only; group B (sham) given EA needles at PC4 (Ximen) and PC6 (Neiguan) but no stimulation; and group C (EAS) electrically given EAS of the ipsilateral PC4 and PC6 throughout the surgery. The EAS consisting of a disperse-dense wave with a low frequency of 2 Hz and a high frequency of 20 Hz, was performed 30 min prior to induction of general anesthesia and continued through the surgery. At the emergence, sufentanil infusion was given for postoperative analgesia with loading dose of 7.5 μg, followed by a continuous infusion of 2.25 μg/h. The patient self-administration of sufentanil was 0.75 μg with a lockout of 15 min as needed. Additional breakthrough pain was treated with dezocine (5 mg) intravenously at the patient's request. Blood samples were collected before (T1), 2 h (T2), 24 h (T3), and 48 h (T4) after operation to measure the plasma β-EP, PGE2, and 5-HT. The operative time, the total dose of sufentanil and the dose of self-administration, and the rescue doses of dezocine were recorded. Visual Analogue Scale (VAS) scores at 2, 12, 24 and 48 h postoperatively and the incidence of apnea and severe hypotension were recorded. The results showed that the gender, age, weight, operative time and remifentanil consumption were comparable among 3 groups. Patients in EAS group had the lowest VAS scores postoperatively among the three groups (P<0.05). The total dose of sufentanil was 115±6.0 μg in EAS group, significantly lower than that in control (134.3±5.9 μg) and sham (133.5±7.0 μg) groups. Similarly, the rescue dose of dezocine was the least in EAS group (P<0.05) among the three groups. Plasma β-EP levels in EAS group at T3 (176.90±45.73) and T4 (162.96±35.00 pg/mL) were significantly higher than those in control (132.33±36.75 and 128.79±41.24 pg/mL) and sham (136.56±45.80 and 129.85±36.14 pg/mL) groups, P<0.05 for all. EAS could decrease the release of PGE2. Plasma PGE2 levels in EAS group at T2 and T3 (41±5 and 40±5 pg/mL respectively) were significantly lower than those in control (64±5 and 62±7 pg/mL) and sham (66±6 and 62±6 pg/mL) groups. Plasma 5-HT levels in EAS group at T2 (133.66±40.85) and T3 (154.66±52.49 ng/mL) were significantly lower than those in control (168.33±56.94 and 225.28±82.03) and sham (164.54±47.53 and 217.74±76.45 ng/mL) groups. For intra-group comparison, plasma 5-HT and PGE2 levels in control and sham groups at T2 and T3, and β-EP in EAS group at T3 and T4 were significantly higher than those at T1 (P<0.05); PGE2 and 5-HT levels in EAS group showed no significant difference among the different time points (P>0.05). No apnea or severe hypotension was observed in any group. It was concluded that intraoperative ipsilateral EAS at PC4 and PC6 provides effective postoperative analgesia for patients undergoing radical esophagectomy with remifentanil anesthesia and significantly decrease requirement for parental narcotics. The underlying mechanism may be related to stimulation of the release of endogenous β-EP and inhibition of inflammatory mediators (5-HT and PGE2).

OBJECTIVETo explore the therapeutic effect of qi benefiting blood activating method (QB-BAM) on acute exacerbation of chronic obstructive pulmonary disease (AECOPD) patients with blood stasis syndrome (BSS) by observing its effect on plasma fibrinogen (Fg) and D-dimer (D-D) levels.

METHODSSixty AECOPD patients with BSS were randomly assigned to the treated group and the control group, 30 in each group. All patients received conventional therapy for AECOPD. Those in the treated group were additionally injected with Shengmai Injection and Tanshinone IIA Injection. Clinical efficacy and indices including levels of Fg, D-D, PaO2, and PaCO2 were measured and compared before and after treatment.

RESULTSThe effective rate was 93.3% (28/30 cases) in the treated group, higher than that of the control group [73.3% (22/30 cases) , P < 0.05]. There was no significant difference in all indices between the treated group and the control group before treatment (P >0.05). After treatment all indices were significantly improved in the two groups (P < 0.01). But in the treated group levels of Fg and D-D decreased more and levels of PaO2 increased more (P < 0.01). Plasma levels of Fg and D-D levels were negatively correlated with PaO2 (r = -0.493, r = -0.438, P < 0.01) before treatment, and also negatively correlated with PaO2 (r = -0.452, r = -0.325, P < 0.01, P < 0.05) after treatment, but they were not significantly correlated with PaCO2 before and after treatment (P >0.05).

CONCLUSIONSQBBAM could play a therapeutic role in improving prethrombotic states of AECOPD patients with BSS. Plasma levels of Fg and D-D were related to the severity of AECOPD.

OBJECTIVETo observe the efficacy difference of electroacupuncture and auricular acupuncture in the treatment of methamphetamine withdrawal syndrome.

METHODSNinety male patients of methamphetamine addiction were randomized into an electroacupuncture group, an auricular acupuncture group and a control group, 30 cases in each one. In the electroacupuncture group, Neiguan (PC 6), Shenmen (HT 7), Zusanli (ST 36), Sanyinjiao (SP 6), Jiaji (EX-B 2) at T5 and L2 were selected bilaterally. In the auricular acupuncture group, jiaogan (AH(6a)), shenmen (TF4), fei (CO14) and gan (CO12) were selected unilaterally. The treatment was given 3 times a week, totally 12 treatments were required. In the control group, no any intervention was applied. Separately, before treatment and after 1, 2, 3 and 4 weeks treatment, the scores of methamphetamine withdrawal syndrome, Hamilton anxiety scale and Hamilton depression scale were observed in each group.

RESULTSThe total score of methamphetamine withdrawal syndrome, anxiety score and depression score were obviously reduced in 2, 3 and 4 weeks of treatment as compared with those before treatment in the electroacupuncture group and the auricular acupuncture group (all P < 0.05), and showed a trend of gradual decline as the extension of treatment. In 1,2,3,4 weeks of treatment, the total score of withdrawal syndrome, anxiety score and depression score in the electroacupuncture group and auricular acupuncture group were lower significantly than those in the control group (all P < 0.05), in which, the total score of withdrawal syndrome in the electroacupuncture group was lower significantly than that in the auricular acupuncture group in the 4th week of treatment (3.69 +/- 2.446 vs 5.73 +/- 3.169, P < 0.05); the anxiety scores were lower significantly than those in the auricular acupuncture group in 3 and 4 weeks of treatment (8.19 +/- 4.57 vs 9.65 +/- 4.24, 5.27 +/- 2.89 vs 7.38 +/- 3.10, both P < 0.05); the depression scores were lower significantly than those in the auricular acupuncture group in 2, 3 and 4 weeks of treatment (15.35 +/- 5.64 vs 19.81 +/- 5.37, 10.96 +/- 4.52 vs 15.00 +/- 4.53, 7.96 +/- 2.69 vs 12.35 +/- 3.59, all P < 0.05).

CONCLUSIONElectroacupuncture at the body points and auricular acupuncture play the therapeutic role in the treatment of methamphetamine withdrawal syndrome, anxiety and depression. The longer time the treatment is with electroacupuncture at the body points, the more obvious the efficacy will be on the above symptoms.

AIM: (1) To investigate the effect of amniotic membrane transplantation (AMT) on rabbit conjunctival surface reconstruction with severe alkali burns. (2) To evaluate the possibility of AMT treatment for ocular alkali burns during recovering stage.METHODS: Animal models were established on 30 eyes of rabbits by creating severe alkali burns on the conjunctiva from the upper corneal limbus to the upper conjunctival fornix.Preserved human amniotic membrane transplantations and reconstruction of conjunctival fornix were performed at one week after injury (recovering stage). Epithelium growth of burned area after transplantation was observed using light microscope at 1, 2, 3, 4, and 8 weeks. Conjunctival tissue in transplantation area was collected at 1, 4 and 8 weeks. The ultrastructure of the collected tissue was studied by electron microscope. The results were compared with control group,which received only vitamin C subconjunctival injection and antibiotic eye drops as treatment for alkali burn. Exterior eye pictures were also taken at the end of the observation, the width from upper corneal limbus to the edge of upper fornix was measured. Data was analyzed statistically.RESULTS: 1) Tn the transplant group, conjunctival epithelium growth was observed in the area of AMT under both light and electron microscope 1 week after surgery. At 4weeks, conjunctival epithelium with goblet cells that resembled normal conjunctival tissues was observed in the whole amniotic membrane area. At 12 weeks, the conjunctival epithelium on the amniotic membrane was well formed, and the connective tissue under the epithelium was loose at the fornix. No fibrosis was identified. In contrast, conjunctival epithelium necrosis was observed in the control group at 2weeks after alkali burns. Re-epithelization did not occur through the 12-week observation. Severe fibrosis with inflammatory cells infiltration was observed between 4 to 8weeks. At 12 weeks, fibrosis of the connective tissue at the fornix developed and there were no conjunctival epithelium covering the burned area. 2) In the transplant group, the conjunctiva in transplanted area had no scarring and appeared smooth at 12 weeks. Upper fornix was reconstructed. The depth of fornix was 7.9±0.3mm (7.6-8.2mm), which was approximate to the normal depth 8.2±0.2mm (8.0-8.4 mm,P＞.05). While in the control group, the burned area appeared rough with granuloma formation and severe scarring. Upper fornix became shallow. The depth of fornix was 3.1±1.7mm(1.0 to 4.5mm.), and significant difference was found between control and transplant group (P＜0.01).CONCLUSION: Human amniotic membrane preserved in glycerin can promote cell adhering, migrating and differentiating of normal conjunctival epithelium.Reconstruction of conjunctival surface in early stage of alkali burn can be achieved by AMT. AMT can effectively prevent symblepharon formation.

BACKGROUND:Since cannulated screw has been applied to femoral neck fracture, it is not uncommon that the screw wear penetrates or refunds. What factors affect the stability of cannulated screw for treatment of femoral neck fractures in adults remains unclear. ＜br> OBJECTIVE:To explore factors related to internal fixation failure by cannulated screws in treatment of adult femoral neck fracture and improve the stability of the adult femoral neck fracture by cannulated screws. ＜br> METHODS:A total of 92 adult patients of femoral neck fracture were treated by cannulated screws in our department between June 2007 and June 2011. Their data were retrospectively analyzed. According to clinical information and fol ow-ups, we selected factors such as age, gender, Garden type of fracture, preoperative skeletal traction, timing of surgery, Garden index, standards of pedicle screws, pedicle screw shapes, partial weight bearing time and postoperative complications, which may affect the success rate of cannulated screws for ＜br> treating femoral neck fracture. The selected factors were then grouped and assigned, after unrelated factors were excluded by one-way χ2 analysis, multiariable Logistic regression analysis was performed. ＜br> RESULTS AND CONCLUSION:The involved 92 patients were fol owed up for 18-72 months. According to Harris assessment criteria, hip function was excellent in 28 cases, good in 25 cases, fair in 17 cases, and poor in 22 cases at the final fol ow-up, the excellent and good rate was 58%. Radiographic results showed that, the patients were divided into two groups according to the presence of the displacement, GardenⅠ (n=22) and GardenⅡ (n=29) as a group, and Garden Ⅲ (n=25) and Garden Ⅳ (n=16) as the other group, the fixation failure rate was 12%and 39%, respectively. In normol and abnormal Garden Index groups, the fixation failure rate was 16%and 59%, respectively. In nail position standards and non-attainment standards groups, the fixation failure rate was 19%and 70%, respectively. In the complication and non-complication groups, the fixation failure rate was 14%and 55%, respectively. These factor groups showed significant differences (P＜0.05). Multiariable Logistic regression analysis showed that, Garden type of fracture, Garden index, standards of pedicle screws, and postoperative complications are the risk factors for internal fixation failure using cannulated screws in treatment of the adult femoral neck fracture.

200 citrinin mutants were screened with the inhibition zone method from the transformants library of Monascus ruber M-7 by Agrobacterium-mediate DNA transfer, which contains more than 5,000 transformants.Then 53 mutants, whose citrinin contents ranged from 0.04?g/g to 154.57?g/g in the red fermented rice (RFR), were achieved by high performance liquid chromatography (HPLC).Color values of RFR prepared by these mutants were also detected.The results showed that there was a positive correlation between the citrinin content and the color value among the mutants.These results provide materials and research bases for ferrther studying the relationship between the production of citrinin and pigment of Monascus ruber at molecular level.

OBJECTIVETo observe the protective effect of active fractions of Huanglian Jiedu Decoction (HJD) on primary cortical neuron injury after oxygen-glucose deprivation (OGD)/reperfusion (R) injury. Methods Using macroporous resin method, HJDFE30, HJDFE50, HJDFE75, and HJDFE95 with 30%, 50%, 75%, and 95% alcohol were respectively prepared. Then the content of active components in different HJD fractions was determined with reverse phase high-performance liquid chromatography (RP-HPLC). The OGD/R injury model was induced by sodium dithionite on primary cortical neurons in neonate rats. MTT assay was used to observe the effect of four fractions (HJDFE30, HJDFE50, HJDFE75, and HJDFE95) and seven index components of HJD on the neuron viability.

RESULTSRP-HPLC showed active component(s) contained in HJDFE30 was geniposide; baicalin, palmatine, berberine, and wogonside contained in HJDFE50; baicalin, berberine, baicalein, and wogonin contained in HJDFE75. The neuron viability was decreased after OGD for 20 min and reperfusion for 1 h, (P <0. 01), and significantly increased after administered with HJD, HJDFE30, HJDFE50, and HJDFE75 (P <0. 05, P <0. 01). Geniposide, baicalin, baicalein, palmatine, wogonside, and wogonin could increase the cortical neuron viability (P <0. 05, P <0. 01).

CONCLUSIONSHJDFE30, HJDFE50, and HJDFE75, as active fractions of HJD, had protective effect on primary cortical neuron injury after OGD/R. Furthermore, geniposide, baicalin, and baicalein were main active components of HJD.
