The effect of acupuncture at the acupoints of 12 meridians on gastrointestinal and cardiac electricity in healthy adults was studied. Specific regulation between meridian points and viscera was also investigated. An electrogastrogram (EGG),electrointestinogram (EIG), carotid pulse graph, phonocardiogram and electrocardiogram were obtained in 30 healthy adults before and after acupuncture at various acupoints of 12 meridians. The effects of acupuncture on the amplitude and frequency of the EGG, EIG, pre-ejection period and the left ventricular ejection time were then analyzed. Acupuncture revealed that LR3 decreased the amplitude of the EGG while LI11 (Quchi), SJ5 (Waiguan), ST36 (Zusanli), SP9 (Yinlingquan) and SI6 (Yanglao) increased the amplitude. Multiple comparisons among the latter five acupoints indicated that there were significant differences between SP9, LI11, SJ5and ST36 (p < 0.01, p < 0.01, p < 0.05) and SI6, LI11 and SJ5 (p < 0.01, p < 0.05). SP9effected EGG amplitude the most, followed by SI6, ST36, SJ5 and LI11. Four acupoints increased the amplitude of the EIG (p < 0.05), including HT5 (Tongli), GB34(Yanglingquan), SP9 and SI6. No significant differences were observed between these acupoints, but SI6 showed the most obvious effect on EIG amplitude, followed by GB34, SP9 and HT5. No significant effects on the frequency of the gastrointestinal slow wave or on cardiac function indexes were observed. Effects were observed, however,on pre-ejection period and left ventricular ejection time. Routine acupuncture had no detrimental effects on the stomach, intestine and heart in healthy adults,but instead regulated physiological function within a normal range. These findings demonstrate the existence of specific connections between the meridian points and the viscera. The results suggest that multiple meridians control the same viscus,and the same meridian can regulate the functions of multiple viscera.

Background: Several studies have investigated predictive and prognostic biomarkers for patients treated with anti-epidermal growth factor receptor (EGFR) agents in lung cancer. However, the conclusion is controversial. Materials and Methods: A meta-analysis was conducted to evaluate the associations of mutant K-ras, PIK3CA and PTEN deficiency with the efficacy of anti-EGFR agents in lung cancer. The primary endpoint was objective response rate (ORR). The secondary endpoints were overall survival (OS) and progression-free survival (PFS). Results: A total of 61 studies were included in the final meta-analysis. The result showed that K-ras mutation was a good predictor for ORR (RR=0.42, 95%CI, 0.33-0.55, p=0.000) and an effective prognostic marker for OS (HR=1.37, 95%CI, 1.15-1.65, p=0.001) and PFS (HR=1.33, 95%CI, 1.05-1.69, p=0.019). However, PTEN deficiency or PIK3CA mutation did not show any significance predictive value for ORR (PTEN, RR=0.82, 95%CI, 0.56-1.19, p=0.286; PIK3CA, RR=1.08, 95%CI, 0.17-6.66, P=0.938). And PTEN deficiency or expression of PIK3CA did not show significance prognostic value for OS (PTEN, HR=0.88, 95%CI, 0.31-2.46,P=0.805; PIK3CA, HR=0.79, 95%CI: 0.23-2.68, P=0.706). Conclusions: Our meta-analysis showed that K-ras mutation may be an effective predictor in lung cancer patients treated with anti-EGFR agents. Whereas, the predictive and prognostic value of PTEN deficiency and PIK3CA mutation need to be further investigated.

Neurofibromatosis type 1 (NF-1) is an autosomal dominant disorder. Pseudoaneurysms formation and rupture is an unusual complication of neurofibromatosis. To date, pseudoaneurysm of the internal pudendal artery associated with NF-1 has not been reported. In this article, we present a 62-yr-old man with NF-1 suffering from spontaneous hematoma of the perinea and scrotum. A digital substraction angiography disclosed a ruptured pseudoaneurysm of the right internal pudendal artery, which was successfully managed with transcatheter embolization.

2-methyl-9,10-bis(naphthalen-2-yl)anthracene (MADN) based fluorescent blue organic light-emitting diodes (OLEDs) are demonstrated. With MADN as emitting layer, experiments indicate that thick MADN (40e60 nm) is preferable for constructing efficient blue OLED. With MADN as hole-transport and emitting layer and tris(8-hydroxy-quinolinato)aluminium (Alq3) as electron-transport layer, the OLED electroluminescent characteristics show a mixture emission of MADN and Alq3 with Commission Internationale d'Eclairage (CIE) color coordinates of (0.25, 0.34), indicating feasible hole transporting in MADN. Using 4,7-diphenyl-1,10-phenanthroline (BPhen) replacing Alq3 as electron-transport layer, the OLED shows deep blue emission with a maximum luminous efficiency of 4.8 cd/A and CIE color coordinates of (0.16, 0.09). The hole transport characteristics of MADN are further clarified by constructing hole-only device and performing impedance spectroscopy analysis. The results indicate that MADN shows superior hole-transport ability which is almost comparable to typical hole-transport material of N,N0-bis(naphthalen-1-yl)-N,N0-bis(phenyl)-benzidine (NPB), suggesting a promising application for constructing efficient blue OLED with integrated hole-transport layer and emitting layer.

Objective: To investigate the clinical efficacy of individual endovascular management for the treatment of different traumatic pseudoaneurysms presenting as intractable epistaxis. Materials and Methods: For 14 consecutive patients with traumatic pseudoaneurysm presenting as refractory epistaxes, 15 endovascular procedures were performed. Digital subtraction angiography revealed that the pseudoaneurysms originated from the internal maxillary artery in eight patients; and all were treated with occlusion of the feeding artery. In six cases, they originated from the internal carotid artery (ICA); out of which, two were managed with detachable balloons, two with covered stents, one by means of cavity embolization, and the remaining one with parent artery occlusion. All of these cases were followed up clinically from six to 18 months, with a mean follow up time of ten months; moreover, three cases were also followed with angiography. Results: Complete cessation of bleeding was achieved in all the 15 instances (100%) immediately after the endovascular therapies. Of the six patients who suffered from ICA pseudoaneurysms, one presented with a permanent stroke and one had an episode of rebleeding requiring intervention. Conclusion: In patients presenting with a history of craniocerebral trauma, traumatic pseudoaneurysm must be considered as a differential diagnosis. Individual endovascular treatment is a relatively safe, plausible, and reliable means of managing traumatic pseudoaneurysms.

The zinc phosphate nanocrystals were synthesized by the ultrasonic – hydrothermal synergisticroute. The ultrasonic – hydrothermal synergistic route can not only decrease the size of the zincphosphate material, but also improve the crystallinity of the product. The transmission electronmicroscopy (TEM) image showed that the needle-like zinc phosphate product was 200 – 300 nmin length and 70 – 80 nm in width. The anti-corrosion tests revealed that the salt atmosphere-resistant time about 1056 h was longer than 768 h common zinc phosphate materials in themarket. The mechanisms of ultrasonic – hydrothermal synergistic route and anti-corrosion werediscussed.
