To the Editor:Biliary stricture formation at the bilioenteric anastomosis is an infrequent complication(2%-3%)after pancreaticoduodenectomy;the average presentation is within 13-14 months(range from 1 month to 9 years)after surgery[1,2].While the etiology is unknown,development of biliary stricture has shown to be more likely if a bile leak occurs in the postoperative period[3,4]and with younger patients[5].

SOIL erosion in the hilly region of Shanxi and Shaanxi provinces is very severe, and unreason-able land use is the main reason. There have been many research reports on the prediction ofsoil erosion, and most of them use regression methods. The resulting co-relative equations areused to predict small-scale erosion of fields or farms and to select agricultural measures.

The nonlinear behaviors of plane coupled motions for a given two-point tension mooring system, are discussed in the present paper. For a cylinder moored by two taut lines under the action of gravity, buoyance and forces due to wave-current and mooring lines, a mathematical model of motions with three degrees of freedom is established. The steady solution and stability are analyzed. By integrating the equations of motions, history, phase map and Poincare map are obtained. The Liapunov exponents are also computed. The numerical results show that: the horizontal movement will increase, and stability will also increase as the steady force increases. The amplitude of responses will decrease as time-dependent forces decrease. Because of the geometric nonlinearity, there exist many windows bifurcating to pseudo-periodic or multi-periodic solution. The bifurcating patterns may be different. The behaviors are very complex. Under wave excitation alone, the motions are nonsymmetrical but still symmetrical statistically.

Elapsed time of serrations in AI-Li single crystals was investigated with two definitions: one is the time elapsed in one cycle of serrations, the other is the average elapsed time within a strain limit. Elapsed time of individual serration appears independent on stress drops during serrated flow. It primarily distributes within the limits of short elapsed time in peak aged condition compared with underaged and overaged conditions, corresponding to low level of the average elapsed time that appears indifferent to increasing strain. It seems that shearing behaviour of delta' particles could be responsible for the variations in elapsed time of serrations.

AIM： To investigate the safety and efficacy of the formulation HD-03/ES capsules in the management of patients with chronic hepatitis B infection.METHODS： A total of 25 patients were recruited to the study and were given HD-03/ES, two capsules twice daily for six months. Clinical assessment of symptoms and signs were done using the ＂clinical observation table＂ once a month before and after the treatment. Biochemical investigations of total bilirubin, ALT, AST, serum protein for liver function tests were done every month after initiating treatment. Serum was analyzed for HBV markers for HBsAg, HBeAg and HBV DNA at baseline, 4 and 6 mo alter therapy using ELISA kits from Roche.RESULTS： After 6 mo of therapy with HD-03/ES, a significant reduction of ALT values from 66.5 ± 11.1 to 39.1 ± 5.2 （P 〈 0.01） and a significant HBsAg loss （52%, P 〈 0.001）, HBeAg loss （60%, P 〈 0.05） and HBV DNA loss （60%, P 〈 0.05） was observed. Adverse effects were mild and never warranted withdrawal of the drug.CONCLUSION： The results of this pilot study indicate that HD-03/ES might be a safe and effective treatment for chronic hepatitis B infection and a long-term multicentric comparator trial is warranted and under way.

The Salem/Hope Creek nuclear plant in southern New Jersey is one of just four U.S. plants with three large reactors (all others consist of one or two). These reactors started operations in 1976, 1980, and 1986 and routinely released toxic radioactive gases and particles into the environment. Only a single study has been performed by federal officials on cancer near nuclear plants—a study now 30 years old. A review of official mortality data using four-year periods shows the Salem County cancer death rate was consistently just below that of other New Jersey counties up to the mid-1980s. However, from 1983-1986 to 2015-2017, the county rate soared from -5.4% below the rest of the state to +32.6% above. The county/state mortality ratio for all causes also increased rapidly in these periods, from +0.6% above to +28.4% above the state. Salem now has the highest cancer death rate, and the 2nd highest total death rate of any New Jersey county. Had the 1983-1986 county-state ratios not changed in the following 31 years, 3493 fewer deaths (1018 of them from cancer) would have occurred among Salem County residents. The lack of any apparent etiologies that could have caused such a dramatic and unexpected change, plus the fact that the Salem/Hope Creek reactors are aging, corroding, and more prone to leaking radionuclides, emphasizes the immediate need for more studies of this type, and the inclusion of local health as a crucial factor in public decisions on the plant’s future.
