[Anatomic study and clinical application of thinned posterior tibial artery perforator flap].

Objective: To explore the feasibility and therapeutic effect of thinned posterior tibial artery free perforator flap for the reconstruction of soft tissue defects at dorsum of hands.

Methods: Six fresh adult lower limbs specimens were injected with red latex via arterial cannula and dissected. The number, distribution, branches, and outer diameter of posterior tibia artery perforators were observed.

[Factors related to the outcome of patients with chronic severe hepatitis B and effectiveness of antivirus therapy].

Objective: To investigate the factors related to the outcome of patients with chronic severe hepatitis B and effectiveness of antivirus therapy.

Methods: The effects of the factors including age, prothrombin activity (PTA), serum HBeAg, Anti-HBe, HBV-DNA load, with or without complication, antivirus therapy and so on, on outcome of 330 patients with chronic severe hepatitis B were analyzed in this retrospective study.

Results: The mortality of patients with chronic severe hepatitis B was significantly higher among patients at higher age, with lower PTA, and with more complications.

[Spectrophotometric determination of azithromycin by charge transfer reaction].

The charge transfer interactions of Azithromycin and 7,7,8,8-tetracyanoquinodimethane (TCNQ) or chloranilic acid (CL) were investigated by spectrophotometry. The apparent molar absorptivity of TCNQ complex is 2.7 x 10(4) L x mol(-1) x cm(-1) at 743 nm, and 5.

[Expression of caspase-3 mRNA in the hippocampus of seven-day-old hypoxic-ischemic rats and the mechanism of neural protection with magnesium sulfate].

Objective: There was consanguineous relationship between caspase-3 and early damage after hypoxia and ischemia. Caspase-3 plays a key role in the process of apoptosis in neuron. Magnesium sulfate could protect neuron from injuries, but the mechanism was not clear.

[Premature, low birth weight, small for gestational age and childhood cerebral palsy].

Objective: To investigate the relationship between perinatal risk factors such as premature, low birth weight, small for gestational age and childhood cerebral palsy (CP).

Methods: A cross sectional survey was carried out among 305,263 children aged 1 - 6 years old in seven cities of Jiangsu Province, China from May to July 1997. The perinatal risk factors were analysed.

[Study on determination of protein with Arsenazo I using resonance light scattering technique].

A new RLS (Resonance light scattering) probe is presented in this paper. In the Britton-Robinson buffer at pH 3.29, Arsenazo I combines with proteins by intermolecular forces, resulted in an enhanced Rayleigh light scattering.
