[Construction of GJB2 mutations common in Chinese EGFP fusion protein vectors].

Objective: To construct GJB2 gene mutations common in Chinese EGFP fusion protein vectors, and to search for better way to study the mechanism of deletion mutations in GJB2 gene.

Method: Non-fusion protein vectors of 235delC, 299-300 del AT and 176 del 16 bp were first made by point mutation methods in vitro. Then expression part of the upper 3 mutations were amplified by PCR and the PCR products were cloned into TA cloning vector.

Vindesine-induced neuropathy mimicking Guillain-Barré syndrome.

A 13-year-old girl with acute lymphoblastic leukaemia, who was being treated with chemotherapy (including vindesine), developed paraplegia without paresthesia, which mimic Guillain-Barré syndrome. Spinal fluid analysis showed a normal protein level, vindesine neuropathy seemed to be the cause of the patient's neurological symptoms. The patient seemed to benefit from human normal immunoglobulin therapy and recovered 4 weeks later.

Clinical evaluation of the recombinant 38 kDa protein of Mycobacterium tuberculosis.

The diagnosis of tuberculosis remains among public health concerns due to shortcomings of the purified protein derivative (PPD). Recombinant truncated 38 kDa protein (rTPA38) of Mycobacterium tuberculosis was evaluated to screen new tuberculosis-specific tuberculin. 539 patients, 1133 healthy controls, and 55 guinea pigs were recruited to assess their sensitivity and specificity to rTPA38; 221 healthy controls, with negative responses to rTPA38 and PPD, were vaccinated with M.
