When looking back to the literature regarding insomnia, it is believed that "disharmony of stomach leads to insomnia" is an important mechanism for the attack of insomnia. This theory is widely accepted in clinical practices by ancient and modern acupuncturists, thus the method treating insomnia from the stomach is developed. But deeper research on its mechanism is still lacking. Through correlation between stomach meridian and heart meridian, spleen and stomach being the pivot of rise and decline of qi movement and yin-yang and being the pivot of five zang-viscera housing spirit, modern abdomen-brain theory and experimental research, the mechanism of treating insomnia from the stomach is discussed in this paper, so as to be better to guide clinical acupoint-selection and treatment.

Objective To evaluate the medium and long-term therapeutic results of percutaneous transhepatic angioplasty for portal vein stenosis (PSV) following pediatric liver transplantation.Methods From Jan.2008 to Dec.2012,5 cases with PVS after pediatric liver transplantation received percutaneous transhepatic angioplasty.There were 3 male and 2 female cases ranging from 7 months to 8 year-old with the median age of 2 years and 10 months.The protopathy included 1 Carolis disease and 4 congenital biliary atresia.The therapeutic results were monitored by clinical follow-up and imaging examination.The clinical data,imaging examination and therapeutic results were analyzed.Results All interventions were performed successfully,and the treatment efficacy was 100％.One patient was diagnosed with earl-onset PVS at 0.5 month after liver transplantation.Four patients were diagnosed with late-onset PVS at 3-30 months after liver transplantation.The prestenotic portal venous average diameter was (2.3 ± 0.6) mm (1.2-3.0 mm),the degrees of stenosis were 70％-95％.The poststenotic portal venous average diameter was (9 ± 1) mm (8-10 mm) (t =32.560,P ＜ 0.05).The prestenotic portal venous average pressure gradient was (11.0 ± 3.2) mmHg (8-16 mmHg),and the poststenotic portal venous pressure gradient was(2.2 ± 1.5) mmHg(0-4.0 mmHg) (t =8.242,P ＜ 0.05).Postoperative follow-up was 10-66 months,the portal veins of all cases were patent,and patency rate was 100％.Conclusions Percutaneous transhepatic stent angioplasty is an effective and safe method for treatment of PVS following liver transplantation.Its medium and long-term patency rates are high.

AIM: To investigate the role of N-cadherin in the delamination of neural crest cells. METHODS: The normal expression of N-cadherin in neural tube was identified using in situ hybridization. The cells with N-cadherin over expression were obtained by transfection of wild-type N-cadherin (wt-N-cadherin) ,and the cells with N-cadherin silencing expression were obtained by transfection of dominant-negative N-cadherin (dn-N-cadherin). The migration of cranial neural crest cells was determined by the technique of immunohistochemistry. RESULTS: Either overexpression or down-regulation of N-cadherin significantly affected the migration of cranial neural crest cells. CONCLUSION: Delamination and migration of the cranial neural crest cells rely on the relative N-cadherin expression in the neural tube during neurulation.

This article presented our experience on transcatheter arterial chemoembolization (TACE) and portal vein embolization (PVE) before hepatic resection for huge hepatocellular carcinoma with cirrhosis.The preoperative future liver remnant/total estimated liver Volume (FLR/TELV) ratios of 5 patients were less than 40％,and preoperative TACE was implemented 3 weeks after PVE.In all these patients,right hepatectomy was successfully implemented.Preoperative TACE and PVE expanded the indication of hepatectomy,increased the safety of surgery and improved the curative rate.

Objective To evaluate the therapeutic results of percutaneous transhepatic stent angioplasty in patients with portal vein stenosis following liver transplantation.Methods From 2005 to 2013,38 patients developed portal vein stenosis following liver transplantation.Percutaneous transhepatic angioplasty of the portal vein stenosis was performed on these patients.The results were monitored by clinical follow-up and imaging studies.Results Percutaneous transhepatic angioplasty was successful in these patients.Self-expanding metallic stents (n=7),balloon-expandable coronary stent (n=29),and membranous stent (n=1) were used.The follow-up period ranged from 3 to 90 months.Portal venous patency was maintained in 34 patients (one patient died due to multi organ failure,1 patient accepted a third liver transplantation because of biliary tract complication,and 1 patient received a repeat placement of a membranous tent because the portal vein stent was blocked by a tumor thrombus,and 1 patient developed stent restenosis).There was 1 patient who developed hemorrhage in the early postoperative period (2.63％).A diagnosis of hepatic artery hemorrhage was made by hepatic artery angiography and the patient was treated by interventional embolization.Conclusion Percutaneous transhepatic stent angioplasty is an efficacious and safe method to treat portal vein stenosis following liver transplantation.

Objective To evaluate the therapeutic effectiveness of percutaneous endovascular treatment of hepatic venous outflow obstruction (HVOO)after pediatric liver transplantation(LT).Methods From January 2008 to January 2013,10 children with obstruction of hepatic vein (HV) or inferior vena cava (IVC) anastomosis underwent percutaneous transluminal angioplasty (PTA) with balloon dilation or stent placement.The hepatic venous outflow obstruction occurred 10-455 days (median,125 days) after pediatric liver transplantation.According to the time of obstruction,the obstruction was divide into early onset (＜1 month) and late onset(＞1 month).The effectiveness of PTA was analyzed.Results Twenty-one procedures were performed.One treatment was ineffective,and technical and initial clinical success ratio was 95.2％ (20/21) and 70.0％ (7/10),respectively.In 3 cases with early onset after LT,operation was performed after unsuccessful PTA in 1 case.One patient who developed recurrent stenosis was treated with PTAS.The other patient died of acute rejection.Late onset after LT was found in 7 cases,who were treated with PTA or stent successfully.Conclusions In cases of venous outflow obstruction resulting from HV and/or IVC lesions after pediatric liver transplantation,percutaneous endovascular treatment with balloon dilation or stent placement is a safe and effective alternative treatment that results in midterm and long-term patency.Early-onset or hepatic veins combined with superior vena cava obstruction should be implanted with stents as early as possible.Late-onset or hepatic veins obstruction alone can be get better results with Balloon Dilatation.

Primary gastric cancer (GC) is one of the most frequently diagnosed cancers worldwide.The incidence of GC in male is approximately twice the incidence thereof in female.Before 60 years of age, the male-female ratio of GC incidence has no geographic and ethic differences, and rises with the increase of age.Studies of classic and molecular epidemiology have proved that the sexual dimorphism in GC is due to synergetic effects of various factors including chronic infection, dietary habit, gene mutation, genetic susceptibility, estrogenic effects and differences in lifestyle behaviors, etc.Studies on the above-mentioned factors can not only help clarify the carcinogenesis of GC, but also help improve the strategies of GC control and prevention, and reducing GC incidence subsequently.

One new dicyclopeptide cyclo-(L-N-methyl Glu-L-N-methyl Glu) (1), together with one new natural dicyclopeptide cyclo-(L-methyl Glu ester-L-methyl Glu ester) (2), and two known dicyclopeptides cyclo-(L-methyl Glu ester-L-Glu) (3), and cyclo-(L-Glu-L-Glu) (4), were isolated from the aerial parts of Dianthus chinensis L. Their structures were determined by spectroscopic analyses and chemical methods.
