Liquidus temperatures in the molten salt system Na3AlF6-K3AlF6-AlF3 of interest for aluminum electrolysis were determined by thermal analysis method. The results were presented and an empirical equation describing liquidus temperatures for primary crystallization was derived t=1003.5–0.081×A2.3159–5.87×B0.657–0.024×A2.22×B1.14＋ 0.035×A2.17×B1.084, where t is the liquidus temperature in degree Celsius, A denotes the mass fraction of AlF3 in system Na3AlF6-K3AlF6- AlF3, and B denotes K3AlF6/（Na3AlF6＋K3AlF6 ） in mass（%, the value was defined as KR in this paper）. The composition limitations are 0w（AlF3）30%, and 0KR50%. The isothermal diagram of molten salt system Na3AlF6-K3AlF6-AlF3 was obtained in this composition limitation.

BACKGROUND Duodenal varices are a lesser-known complication with non-cirrhotic portal hypertension. We report a circuitous route from missed diagnosis of duodenal varices to correction. An extremely rare case of duodenal variceal bleeding secondary to idiopathic portal hypertension(IPH) is expounded in this study, which was controlled by transjugular intra-hepatic porto-systemic shunt(TIPS) plus embolization. CASE SUMMARY A 46-year-old woman with anemia for two years was frequently admitted to the local hospital. Upon examination, anemia was attributed to gastrointestinal tract bleeding, which resulted from duodenal variceal bleeding detected by repeated esophagogastroduodenoscopy. At the end of a complete workup, IPH leadingto duodenal varices was diagnosed. Portal venography revealed that the remarked duodenal varices originated from the proximal superior mesenteric vein. TIPS plus embolization with coils and Histoacryl was performed to obliterate the rupture of duodenal varices. The anemia resolved, and the duodenal varices completely vanished by 2 mo after the initial operation. CONCLUSION TIPS plus embolization may be more appropriate to treat the bleeding of large duodenal varices.

Investigating the transmission of infectious diseases, predicting the epidemic trend of an infectious disease and evaluating the effects of control measures are the continuing subject of public health participators. In recent years the spatial-temporal model has been proposed as a powerful tool to get this information from large incomplete and insufficiently general monitoring data.

Objective To review the transmission models of tuberculosis in heterogeneous population. Data sources The data used in this review were adopted mainly from the studies of models of tuberculosis reported from 1995 to 2006. Study selection Relevant literature on transmission models of tuberculosis in heterogeneous populations are referenced. Results Casual/random factors and genetic factors are the main reasons for epidemics of tuberculosis in recent years. Mass public transport is playing the primary role in casually close contact which can facilitate the transmission of tuberculosis. Genetic susceptibility not only varies endemic prevalence levels, but also drastically alters the effects of treatment for tuberculosis patients. Detailed studies further exhibit that casual contact and genetic factor are responsible for over 30%-40% of the total new cases in recent years. The prevalence of tuberculosis could double （from 33% to 60%） if a genetically susceptible phenotype is present in only 30% of the population. And some challenges have emerged along with these exciting results. Conclusions Casual/random contact, public transport and genetic susceptibility are responsible for most new tuberculosis cases and a wide variation in endemic tuberculosis levels between regions. Hence, the transmission model of tuberculosis in a heterogeneous population can provide more clues to underlying mechanism of tuberculosis transmission than in a homogeneous population. However, many challenges remain for us in understanding transmission of disease.

AIM To explore the natural history of covert hepatic encephalopathy(CHE) in absence of medication *** Consecutive outpatient cirrhotic patients in a Chinese tertiary care hospital were enrolled and evaluated for CHE diagnosis. They were followed up for a mean of 11.2 ± 1.3 mo. Time to the first cirrhosis-related complications requiring hospitalization, including overt HE(OHE), resolution of CHE and death/transplantation, were compared between CHE and no-CHE patients. Predictors for complication(s) and death/transplantation were also *** A total of 366 patients(age: 47.2 ± 8.6 years, male: 73.0%) were enrolled. CHE was identified in 131 patients(35.8%). CHE patients had higher rates of death and incidence of complications requiring hospitalization, including OHE, compared to unimpaired patients. Moreover, 17.6% of CHE patients developed OHE, 42.0% suffered persistent CHE, and 19.8% of CHE spontaneously resolved. In CHE patients, serum albumin 133 μmol/L(HR = 4.75, P = 0.036) predicted mortality. Child-Pugh B/C(HR = 0.084, P < 0.001) and OHE history(HR = 0.15, P = 0.014) were predictors of spontaneous resolution of *** CHE exacerbates, persists or resolves without medication intervention in clinically stable cirrhosis. Triage of patients based on these predictors will allow for more cost-effect management of CHE.

丁香是中国古典诗歌的传统意象,是美丽、高洁、忧郁的象征。自唐代开始,以丁香为题材的作品增多,它作为一种意象也进入诗人的创作视阈,其审美意蕴和情感、思想内涵也得到进一步的拓展。从历代关于丁香的文学作品分析,丁香意象的意蕴是多样性的,有着丰富的人文或社会内涵:或为高洁情趣的象征,独立人格的载体;或借以抒发愁怨、忧伤之情;或烘托恋情等。但是,对丁香意象多义的解读不能忽视其"幽怨"的基本特质。
