Allosteric regulation of nitrate transporter NRT via the signaling protein PII.

Coordinated carbon and nitrogen metabolism is crucial for bacteria living in the fluctuating environments. Intracellular carbon and nitrogen homeostasis is maintained by a sophisticated network, in which the widespread signaling protein PII acts as a major regulatory hub. In cyanobacteria, PII was proposed to regulate the nitrate uptake by an ABC (ATP-binding cassette)-type nitrate transporter NrtABCD, in which the nucleotide-binding domain of NrtC is fused with a C-terminal regulatory domain (CRD).

A Chinese Herbal Decoction, Huoxue Qingyi Decoction, Promotes Rehabilitation of Patients with Severe Acute Pancreatitis: A Retrospective Study.

Severe acute pancreatitis (SAP) still remains an important surgical problem with high morbidity and mortality. The utilization of Traditional Chinese Medicine shows good prospects in therapy of SAP since it has advantages of more extensive pharmacological effects and fewer adverse effects. In this retrospective study, 38 patients received standardized treatment (control group) and 37 patients received Chinese herbal decoction, Huoxue Qingyi Decoction (HQD group), in addition to standard treatment for SAP.

[G6PD deficiency among children under 7 years old from Yunnan with unique ethnic minority origin].

Objective: To investigate the epidemiological status of glucose-6-phosphate dehydrogenase (G6PD) deficiency among children from Yunnan with unique ethnic origins.

Methods: DNA samples from 11759 children were tested with fluorescent spot test, G6PD/6PGD quantitative ratio assay and hemoglobin electrophoresis.

Results: The detection rate of G6PD deficiency was 2.

[A survey on anemia among children under 7 years of age from 15 minority ethnic groups in Yunnan].

Objective: To investigate the level and distribution characteristics of anemia of the minority ethnic group children in Yunnan.

Method: The cases with anemia were surveyed from 13 336 samples of 15 minority ethnic groups and Han children in Yunnan by Taking the method of random cluster sampling.

Result: The prevalence of anemia among the children under 7 years of age of 15 ethnic groups of minority in Yunnan was 13.

Percutaneous transhepatic biliary stenting vs. surgical bypass in advanced malignant biliary obstruction: cost- effectiveness analysis.

Background/aims: This study aims to compare the clinical outcomes and costs between percutaneous transhepatic biliary stenting (PTBS) and surgical bypass.

Methodology: We randomly assigned 142 patients with unresectable malignant biliary obstruction between 2005 and 2010 to receive PTBS or surgical bypass as palliative treatment. PTBS was successfully performed in 70 patients who formed the PTBS group (failed in 7 patients).

Self-expanding metallic stents drainage for acute proximal colon obstruction.

Aim: To clarify the usefulness of the self-expanding metallic stents (SEMS) in the management of acute proximal colon obstruction due to colon carcinoma before curative surgery.

Methods: Eighty-one colon (proximal to spleen flex) carcinoma patients (47 males and 34 females, aged 18-94 years, mean = 66.2 years) treated between September 2004 and June 2010 for acute colon obstruction were enrolled to this study, and their clinical and radiological features were reviewed.
