Objective To analyze the phenotypes of lymphocytes in cerebrospinal fluid derived from the patients with neurosyphilis. Methods Samples of cerebrospinal fluid from 12 patients with neurosyphilis and 20 patients with latent syphilis were collected and analyzed by flow cytometry for CD4 and CD25 expression. Results There was a significant increase in the number of white blood cells in the cerebrospinal fluid of patients with neurosyphilis. FACS analysis showed that most leukocytes were lymphocytes predominated with CD4 + T cells in neurosyphilis patients which were almost 4 times more than that in latent syphilis. However, there was a significant decrease in the proportion of CD4+ CD25high regulatory T cells (Tr) in neurosyphilis patients compared with that in latent syphilis patients. Conclusion A dramatic increase in CD4+ T cell frequency suggested its pathogenic role in neurosyphilis, whereas a decrease in CD25high Tr frequency indicated that CD4 + CD25high Tr cells might play an important role in immune homeostasis of central nervous system.

Objective To assess the clinical presentations and treatment of neurosyphilis with mania as the first manifestation. Methods A retrospective study was performed. Clinical data on neurosyphilis patients with mania as the first manifestation collected from July 2009 to June 2010 were analyzed. Results Twenty cases of neurosyphilis were included in this study, which were all misdiagnosed as schizophrenia, anxiety,cerebral infarction, etc. All the patients had manic symptoms at onset, such as irritability, bad temper, impulsive behavior, disturbance in thinking, and so on. Some patients also suffered from a marked decrease in memory, calculation and cognitive ability. Rapid plasma reagin (RPR) test, Treponema pallidum hemagglutination (TPHA)test and cerebrospinal fluid (CSF) venereal disease research laboratory (VDRL) test were positive in all the patients. Varying degrees of symptomatic improvement was achieved after anti-syphilis and anti-psychotic treatment. CSF was retested in 13 patients 3 months after the end of treatment, and CSF VDRL titer decreased in 10 patients, remained unchanged in 2 patients, and turned negative in 1 patient. Conclusions Neurosyphilis lacks distinctive clinical characteristics. For patients with poor response to conventional antipsychotic therapy,neurosyphilis should be considered, and serology and cerebrospinal fluid tests for syphilis are warranted.

OBJECTIVETo summarize the therapeutic effect of 5 kinds of flaps for the treatment of skin and soft tissue defect in the hallex.

METHODSFrom Jan. 2008 to Jun. 2013, 24 cases with skin and soft tissue defects in the hallex were treated with 5 kinds of reversed flaps, including medial foot dorsal neurocutaneous flaps, medial foot neurocutaneous flaps, lateral tarsal flaps, anterior malleous flaps, medial cross leg and saphenous nerve flaps. The defects size ranged from 3 cm x 2 cm to 5 cm x 3 cm, with the flap size from 3. 5 cm x 2. 5 cm to 5. 5 cm x 4. 0 cm.

RESULTSPartial superficial necroisis happened at the distal end of one foot dorsal medial neurocutaneous flap. One third flap necrosis occurred in 1 foot medial neurocutaneous flap due to too tight suture at flap pedicle and resulted thrombosis. All the other 23 flaps survived completely. 15 cases were followed up for 3-36 months with normal walking function and satisfactory appearance. Among the 8 cases with nerve anastomosis, 4 cases were followed up with 2-point discrimination distance of 8-11 mm. the flaps without nerve anastomosis also had protective sense due to nerve ingrowth.

CONCLUSIONSSkin and soft tissue defects in the hallex can be treated with different appropriate flaps. The hallex length can be reserved with satisfactory function and appearance.
