Journal of Acupuncture and Tuina Science 2015;(1):44-48
Objective:To observe the clinical efficacy of acupoint massage plus moxibustion in treating refractory insomnia.
Methods:Sixty patients with refractory insomnia were randomized into two groups, 30 in each group. The treatment group was intervened by acupoint massage on the face and head plus moxibustion at Yongquan (KI 1);the control group was intervened only by the same acupoint massage. For both groups, the treatment was given once a day, and the therapeutic efficacy was evaluated after 4-week treatment.
Results:The total effective rate was 93.3%in the treatment group versus 80.0%in the control group, and the difference was statistically significant (P<0.05).
Conclusion:Acupoint massage plus moxibustion can produce a better efficacy than acupoint massage alone in treating refractory insomnia.

Objective To comparative analyze the CT enhanced scan and digital substraction angiography (DSA) in showing the residual and new lesions after treatment of transcatheter arterial chemoembolization (TACE).Methods 60 cases of patients with complete clinical information and imaging data from June 2010 to February 2013 were collected,these patients were diagnosed of primary hepatocelluar carcinoma and underwent TACE treatment.The sensitivity and specificity of CT and DSA to detect the residual and new lesions after TACE treatment were analyzed.By analysis of the main factors affecting the low detection rate to seek a method that can improve PHC residual new lesions detection rate after TACE.Results There were 86 lesions in 60 cases,CT enhanced scan clearly determined the diagnosis of 49 lesions (42 residues,7 new lesions).37 lesions did not prompted to tumor recurrence (residual and new lesions).DSA as the gold standard,the sensitivity of CT enhanced scan to check out the lesions was 84.5 % (49/58),specificity was 100.0 % (28/28),the false negative rate was 15.5 % (9/58),the accuracy was 89.5 % (77/86).Enhanced CT detection rate of tumor recurrence was 57.0 % (49/86),the DSA detection rate of tumor recurrence was 67.4 % (58/86).The difference of determining tumor recurrence between the CT enhanced scan and DSA was significant (x2 =7.11,P < 0.05).Conclusions Three dynamic contrast-enhanced CT scan is the first choice for follow-up examination methods after TACE for hepatocellular carcinoma,but many factors will affect the detection rate of the residual and new lesions.Compared with CT examination,DSA examination has more advantages.DSA examination should be performed when the clinical suspicion of tumor recurrence is negative after enhanced CT scan.

Objective To investigate the effects of hyperbaric oxygen preconditioning (HBOP) on brain edema, inflammatory reaction and neuronal cell apoptosis induced by experimental hemorrhage in rats. Method Eighteen male Spraque-Dawley rats, weighing 300 - 350 g,received five successive sessions of HBOP with 3 atmosphere absolute pressure and 100% O2 one hour daily for five successive days, and other eighteen rats received five successive sessions of pretreatment with one atmosphere absolute pressure, air, one hour daily for five successive days. Twenty-four hours after the final pre-conditioning, rats received an infusion of 100 μL autologous blood into the basal ganglion. Seventy-two hours later, rats were sacrificed for brain edema measurements in 12 rats of each group. The histopathological changes around the hematoma were observed microscopically, and the neuronal cell apoptosis was detected by using the terminal deoxynucleotidyl transferase-mediated nick end labeling (TUNEL) in six rats of each group. Data of brain water content were analyzed by using Stata 7.0 software and statistical analysis was carried out by two-tailed Student t -test. Results Compared with the control group, HBOP significantly attenuated brain edema 72 hours after intra-cerebral hemorrhage in experimental rats (81. 6± 0. 7% vs. 82. 8± 0.9%, P < 0.01). Inflammatory cell infiltration and neuronal cell apoptosis were also significantly decreased in the HBOP group. Conclusions HBOP protects the rats against brain edema formation, and quells inflammatory reaction and neuronal cell apoptosis following intra-cerebral hemorrhage in experimental rats.

Objective To evaluate the role of nuclear factor erythroid 2?related factor 2 ( Nrf2)∕antioxidant response element( ARE) signaling pathway in inhibition of lipopolysaccharide ( LPS)?induced inflammatory factor release from macrophages by hydrogen. Methods RAW264. 7 macrophages of mice were cultured in 6?well plates (2×106 cells∕well) and were divided into 4 groups (n=24 each) using a random number table: control group ( group C); LPS group; hydrogen?rich saline+LPS group ( group LPS+H2); Nrf2 small interference RNA (siRNA)+LPS+hydrogen?rich saline group (siRNA+LPS+H2 group) . LPS 1 μg∕ml was added in group LPS. In group LPS+H2 , LPS 1μg∕ml was added, and the cul?ture medium was then replaced with the culture medium containing 0. 6 mmol∕L hydrogen?rich saline. In group siRNA+LPS+H2 , after Nrf2?siRN was successfully transfected into the cells, the cells were continu?ously incubated for 24 h, and the culture medium was then replaced with the culture medium containing 0.6 mmol∕L hydrogen?rich saline after LPS 1 μg∕ml was added. At 24 h of incubation, the supernatant was sep?arated for determination of the lactic dehydrogenase (LDH) activity (using colorimetric method) and for detection of the concentrations of tumor necrosis factor?alpha ( TNF?α) , interleukin?1 beta ( IL?1β) , high mobility group box?1 (HMGB1) and IL?6 (by ELISA). The cells were collected for measurement of the proliferation of cells ( by methyl thiazolyl tetrazolium assay) and for determination of the expression of Nrf2 and heme oxygenase?1 ( HO?1) in cells ( by Western blot) . Results Compared with group C, the LDH activity and concentrations of TNF?α, IL?1β, IL?6 and HMGB1 in the supernatant were significantly in?creased, the proliferation of cells was significantly decreased, and the expression of HO?1 in cells was sig?nificantly up?regulated in LPS and siRNA+LPS+H2 groups, and the expression of Nrf2 in cells was signifi?cantly up?regulated in LPS and LPS+H2 groups (P<0.05). Compared with group LPS, the LDH activity and concentrations of TNF?α, IL?1β, IL?6 and HMGB1 in the supernatant were significantly decreased, the proliferation of cells was significantly increased, and the expression of Nrf2 and HO?1 in cells was sig?nificantly up?regulated in group LPS+H2 , and the expression of Nrf2 and HO?1 in cells was significantly down?regulated in group siRNA+LPS+H2 ( P<0.05) . Compared with group LPS+H2 , the LDH activity and concentrations of TNF?α, IL?1β, IL?6 and HMGB1 in the supernatant were significantly increased, the proliferation of cells was significantly decreased, and the expression of Nrf2 and HO?1 in cells was signifi?cantly down?regulated in group LPS+H2+siRNA ( P<0.05) . Conclusion The mechanism by which hydro?gen inhibits LPS?induced inflammatory factor release from macrophages is related to the activation of Nrf2∕ARE signaling pathway in mice.

A gas chromatography mass spectrometry (GC-MS) method has been developed and fully validated for the simultaneous determination of natural borneol (NB) and its metabolite, camphor, in rat plasma. Following a single liquid-liquid extraction, the analytes were separated using an HP-5MS capillary column (0.25 mm ? 30 m ? 0.25μm) and analyzed by MS in the selected ion monitoring mode. Selected ion monitor (m/z) of borneol, camphor and internal standard was 95, 95 and 128, respectively. Linearity, accuracy, precision and extraction recovery of the analytes were all satisfactory. The method was successfully applied to pharmacokinetic studies of NB after oral administration to Wistar rats.
