Effects of endogenous dopamine induced by low concentration atropine eye drops on choroidal neovascularization in high myopia mice.

Aim: To evaluate effects of endogenous dopamine induced by low concentration atropine eye drops on choroidal neovascularization (CNV) in high myopia mice.

Methods: The C57BL/6J mice were deprived of the right eye for 4wk, and the high myopia was diagnosed by optometry, the diopter was less than -6.00 D, and CNV was induced by 532 nm laser.

Low Serum Hepatitis B Surface Antigen Level Predicts Compensated Cirrhosis Caused by Chronic Hepatitis B in HBeAg Positive Patients in East China.

Backgrounds: Serum hepatitis B surface antigen (HBsAg) levels are associated with fibrosis in patients with chronic hepatitis B (CHB) infection.

Objectives: The aim of our study was to evaluate serum HBsAg level as a biomarker for compensated cirrhosis in hepatitis B e antigen (HBeAg) positive CHB patients.

Patients And Methods: Two-hundred and one HBeAg-positive Chinese CHB patients with or without cirrhosis were enrolled in this retrospective study.

Response-guided treatment of cirrhotic chronic hepatitis B patients: multicenter prospective study.

Aim: To observe the effect of response-guided add-on therapy with adefovir (ADV) and lamivudine (LAM) in cirrhotic hepatitis B (CHB) patients.

Methods: A total of 100 patients with CHB and cirrhosis were divided into three arms according to hepatitis B virus (HBV) DNA level after 24 wk LAM monotherapy: Arm A (complete response, HBV DNA ≤ 60 IU/mL, n = 49), Arm B (partial response, HBV DNA: 60-2000 IU/mL, n = 31) and Arm C (inadequate response, HBV DNA > 2000 IU/mL, n = 20). ADV was added to LAM at week 48 in Arms A and B, but at week 24 in Arm C.

[Effects of different fertilizer application on soil active organic carbon].

The variation characteristics of the content and components of soil active organic carbon under different fertilizer application were investigated in samples of calcareous fluvo-aquic soil from a field experiment growing winter wheat and summer maize in rotation in the North China Plain. The results showed that RF (recommended fertilization), CF (conventional fertilization) and NPK (mineral fertilizer alone) significantly increased the content of soil dissolved organic carbon and easily oxidized organic carbon by 24.92-38.
