Objective To evaluate the value of the short-segment nerve conduction studies (SSCSs, inching test) in the diagnosis and localization of cubital tunnel syndrome (CubTS).Methods The clinical and electrophysiologic data of 46 patients (92 limbs from 32 men and 14 women, aged from 19 to 59 years, with average age of 41.2 years) with CubTS were collected.The symptoms occurred in unilateral arm in 41 patients and bilateral arms in 5 patients, involving 35 left arms and 16 right arms.SSCSs were performed in both arms in all the 46 patients.Sixty ulnar nerves were studied in 30 healthy control subjects using SSCSs.Results The 51 symptomatic arms with CubTS were abnormal in long segment motor nerve conduction studies.There were 68 abnormal arms ( 51 symptomatic arms, 17 asymptomatic arms ) in SSCSs.The lesions were located 2 cm proximal to the elbow-the elbow segment ( AE2-E ) in 41 arms (44.6%),the elbow-2 cm distal to the elbow segment (E-BE2) in 23 arms (25%), 4 cm proximal to the elbow-2 cm proximal to the elbow segment (AE4-AE2) in 18 arms (19.6%), 6 cm proximal to the elbow-4 cm proximal to the elbow segment (AE6-AE4) in 9 arms (9.8%), 2 cm distal to the elbow-4 cm distal to the elbow segment (BE2-BE4) in 8 arms(8.6%) and 4 cm distal to the elbow-6 cm distal to the elbow segment (BE4-BE6) in 6 arms(6.5%),respectively.Conclusions SSCSs are more sensitive in detecting CubTS than the conventional long segment motor conduction studies.SSCSs could precisely localize the entrapment lesions in patients with CubTS ,might be a useful tool for the detection of ulnar mononeuropathy at the elbow, especially for diagnosing the patients with CubTS who have no clinical features or have a normal long segmental nerve conduction findings.

Objective To investigate the clinical presentation,laboratory features,imaging findings and CYP27A1 gene mutations of cerebrotendinous xanthomatosis (CTX) for improving the recognition and the early diagnosis and treatment of the disease.Methods Medical records and 8 months follow-up data of one patient who had been clinical diagnosed as CTX were collected and the pedigree and gene mutation analysis of the patient were carried out.Meanwhile,the clinical characters of CTX were analyzed according to the data from our patient and the review of the literature. Results Patient was a 36 years old male manifested with mental retardation, bilateral corticospinal tract and corticonuclear tract impairment,cerebellar lesions and peripheral neuropathy; head MRI indicated symmetric abnormal signals of bilateral basal ganglia,cerebellar dentate nucleus softening and calcification lesions; Achilles tendon MRI indicated markedly thickened Achilles tendon; gene mutation analysis showed sterol-27-hydroxylase gene( CPY27A1 )C→T homozygous mutation in 1016 nucleotide of exon 5.Ursodesoxycholic acid was given as treatment.In 8 months of follow up,for the first 6 months,the patient took medicine regularly and the illness condition was stable.But for the nearly 2 months,the patient voluntarily stopped medicine and the illness condition was worse.Conclusions CPY27A1 gene C→T homozygous mutation in 1016 nucleotide of exon 5 leads to CTX in the patient, which conforms to the characteristic of autosomal recessive disorder. CTX has some characteristic clinical manifestations,such as Achilles tendon thickening,intelligent declining and so on.But lack of specificity of early radiographic examination makes CTX easy to be delayed diagnosis and treatment.CYP27A1 gene mutation analysis has an important significance for early diagnosis of CTX,which should be paid more attention,while the early application of chenodeoxycholicacid treatment can delay the progression of the disease.

Objectives To report the clinical features and treatment in a case with paroxysmal diagonistic ideomotor apraxia after ischemic infarction of the corpus callosum.Methods The neuropsychological tests,brain MRI,the TCD and carotid duplex sonography were carried out in the patient who is right handed and had had presentation of paroxysmal diagonistic ideomotor apraxia for ten days.Results Neuropsychological tests confirmed the diagnosis of paroxysmal diagonistic apraxia in this patient.MRI showed ischemic infarction in the right corpus callosum.The symptomsin the patient were improved after the treatment with aspirin for three months.Conclusion The infarction of corpus callosum may induce paroxysmal diagonistic apraxia.

Objective To analyze the features of the latency and interval in somatosensory evoked potentials (SEP) of the upper limbs in subacute combined degeneration(SCD),and evaluate the SEP of the upper limbs in the diagnosis of SCD.Methods Thirty-four defined SCD patients and 22 healthy controls were included in this study.The patients underwent the SEP test and the magnetic resonance imaging(MRI)of spinal cord.The SEP results of the patients were compared with those of the controls.The results of the SEP,which were divided into the peripheral part and central part to be evaluated,were also compared with the related results of the SEP and MRI.Results Compared with the controls,the N9 ((10.80 ± 1.07) ms vs (10.23 ± 0.64) ms,t =3.223),P14 ((17.28 ± 2.56) ms vs (14.62 ± 0.84) ms,t =6.643),N9-P14 ((6.48±2.27) ms vs(4.40-0.58) ms,t =5.951) in the upper limbs and N9((12.11 ±0.83) ms vs (10.93±0.56) ms,t=5.690),P30((36.96±5.56) ms vs(30.37±2.20) ms,t=7.217),P38 ((46.94 ±5.83) ms vs(39.80 ±2.54) ms,t =7.353) in the lower limbs of SCD patients were prolonged (all P ＜0.01),however,the P14-N20 was prolonged without statistical significance.The abnormality of SEP was 80.9％ (110/136),in which the abnormality of the upper limbs was 85.3％ (58/68)while that of the lower limbs was 76.5％ (52/68).N9-P14 had the highest abnormality rate which was 72.1％ (49/68).The patients with SCD with normal N9 had prolonged N9-P14 ((5.98 ± 1.90) ms vs(4.40 ± 0.58) ms,t =5.267,P ＜ 0.01).Conclusions Subacute combined degeneration can involve not only the peripheral part of the somatosensory pathway but also the central part including the brainstem and brain.In the SEP of upper limbs,N9-P14 has the highest abnormality rate which suggests that the part from cervical spinal cord to the brainstem may be the most vulnerable in SCD.The test of SEP in the upper limbs may provide evidence for the damage in the central part in SCD.

Objective To analyze the characteristics of the F waves,H-reflex and nerve conductions and its diagnostic value in the patients with Guillain-Barré syndrome(GBS)onset within 4 weeks.Methods The electrophysiological data of the 40 patients with GBS were analyzed retrospectively.These patients were divided into 2 groups according to the duration of illness including in 2 week' s group and over 2 week' s group.The results of the F waves,H-reflex,the motor nerve conduction velocity (MCV),and the sensory nerve conduction velocity(SCV)of these patients were analyzed.Results The abnormality rate of the F waves was 17/20 and 7/18 respectively in less 2 week' s group and over 2 week' s.The H-reflexes were 13/20 and 12/19.The MCV was 28.4％(25/88)and 32.9％(26/79).The distal motor latency was 40.9％(36/88)and 36.7％(29/79).The compound muscle action potential amplitude was 35.2％(31/88)and 32.9％(26/79)respectively in these two groups.The abnormality rate of the SCV was 11.2％(10/89)and 25.2％(24/95)respectively in the two groups.The higher abnormality rate of these tests was the F waves and H-reflex in both the groups.The abnormality rates of the F waves(x2 =8.657,P =0.003)and SCV(x2 =6.002,P =0.014)were significantly different between the two groups.There were no significant differences in the other tests.Conclusion The electrophysiological tests are valuable in the diagnosis of GBS.The F waves and H-reflex are more significant for early diagnosis of GBS.

Objective To evaluate the efficacy and safety of tacrolimus 0.03％ ointment for the treatment of 2-year-old patients with moderate to severe AD.Methods An open-labeled,non-comparative,multi-center study was carried out,which included 59 2-year-old children with moderate to severe AD.All the patients were given topical tacrolimus 0.03％ ointment twice daily for 3 weeks.The evaluation of patients was scheduled at the baseline,1,2,and 3 weeks after the start of treatment.Clinical outcome parameters included the total response rate,eczema area and severity index score (EASI score),the percentage of body surface area (BSA％) affected,physician's global evaluation (PGE),children's dermatology life quality index (CDLQI),visual analog scale (VAS) pruritus score.Safety was assessed based on adverse events reported by patients or observed by the physicians.Results At the end of the treatment,the total response rate was 65.85％ with an EASI score of 4.18,and BSA％ of 16.41％.Of these patients,85.10％ achieved a satisfactory outcome,2.13％ achieved a complete cure,and all achieved an improvement,with no exacerbation observed.The 3-week treatment also resulted in a significant decrease in VAS pruritus score (from 6.80 to 3.21) and CDLQI (frown 7.06 to 2.91).Side effects mainly manifested as temporary burning sensation at the application site,and no severe adverse events associated with tacrolimus were observed.Conclusion Tacrolimus 0.03％ ointment seems safe and effective for the treatment of 2-year-old patients with moderate to severe AD.

Objective To investigate the effects of heat-inactivated Cryptococcus neoformans(H-CN)on an experimental murine model of meningoencephalitis and on IL-1?,IFN-?and TNF-?gene ex-pression on the brain and spleen.Methods An experimental murine model of intracerebral infection with C.neoformans was established.Mice were divided into H-CN-treated group and control group.The brain and spleen of two groups were collected to obtain total RNA,and IL-1?,IFN-?and TNF-?were detected by RT-PCR method.After intracerebral challenging with lethal doses of C.neoformans,the survival time and colony forming units(cfu)of C.neoformans in the brain of two group were observed.Results The survival time was prolonged,and cfu of C.neoformans were decreased in the brain of H-CN-treated group in com-parison with those of control group.Expression of IL-1?was positive,and IFN-?and TNF-?negative in the brain tissue of H-CN-treated mice;while expression of IL-1?,IFN-?and TNF-?was all negative in the control mice,as indicated by RT-PCR.Expression of3cytokines,IL-1?,IFN-?and TNF-?was all positive in the spleen tissue of both groups,suggesting that there was no significant difference in the levels of cytokine gene transcripts in both groups.Conclusion These findings suggest that murine resistance to central nervous system infection of C.neoformans be enhanced by intracerebral administration of H-CN,and anti-cryptococcal mechanism probably involves a local cytokine IL-1?elicitated by H-CN in central nerve system.
