Chest wall tuberculosis is a common extra-pulmonary tuberculosis, which often occurs in lung or pleura tuberculosis, or coexists with tuberculosis in other parts. The final manifestation of the disease is cold abscess on the chest wall, chronic sinuses with repeated exudation after the abscess is broken. At present, There were a series of problems in the diagnosis, treatment, and extremely prognosis of tuberculosis of the chest wall. Therefore, we reviewed the diagnosis of chest wall tuberculosis, including B-ultrasound, chest CT and positron emission tomography/computed tomography (PET/CT), tuberculous infectin of T cells spot test (T-SPOT TB), pathological examination. The related treatments including medical treatment, surgical treatment and other local treatment in order to better understand the chest wall tuberculosis.

BACKGROUNDSleep deprivation (SD) has been used in treatment of depression disorder, and could effectively improve the patients' depressive symptoms.The aim of the study was to explore the effects of SD on electroencephalographic (EEG) and executive function changes in patients with depression.

METHODSEighteen depression patients (DPs) and 21 healthy controls (HCs) were enrolled in the present study. The whole night polysomnography (PSG) was recorded by Neurofax-1518K (Nihon Kohden, Japan) system before and after 36 hours of SD. The level of subjects' depression state was assessed by Visual Analogue Scale (VAS), and the executive function was assessed by Wisconsin Card Sorting Test (WCST).

RESULTSSignificantly decreased sleep latency (SL; before SD: (31.8 ± 11.1) minutes, after SD: (8.8 ± 5.2) minutes, P < 0.01) and REM sleep latency (RL; before SD: (79.8 ± 13.5) minutes, after SD: (62.9 ± 10.2) minutes, P < 0.01) were found after SD PSG in depression patients. Decreased Stage 1 (S1; before SD: (11.7 ± 2.9)%, after SD: (7.3 ± 1.1)%, P < 0.01) and Stage 2 (S2, before SD: (53.8 ± 15.5)%, after SD: (42.3 ± 14.7)%, P < 0.05) of non-rapid eye movement (NREM) sleep, and increased Stage 3 (S3, before SD: (11.8 ± 5.5)%, after SD: (23.6 ± 5.8)%, P < 0.01) and Stage 4 (S4, before SD: (8.8 ± 3.3)%, after SD: (27.4 ± 4.8)%, P < 0.01) NREM sleep were also found. After SD, the depression level in patients decreased from 6.7 ± 2.1 to 2.9 ± 0.7 (P < 0.01). In WCST, the patients showed significantly decreased Response errors (Re, before SD: 22.3 ± 2.4, after SD: 18.3 ± 2.7, P < 0.01) and Response preservative errors (Rpe, before SD: 11.6 ± 3.6, after SD: 9.3 ± 2.9, P < 0.05). Depression patients' RE (t = 2.17, P < 0.05) and Rpe (t = 2.96, P < 0.01) also decreased significantly compared to healthy controls.

CONCLUSIONSD can improve depression symptom and executive function in depression patients.

Objective To evaluate the patency rate of two types of metallic biliary stent in treating malignant biliary stenosis, and to discuss the patient’s survival rate. Methods A total of 126 patients with malignant biliary stenosis were treated with percutaneous implantation of biliary stent. The clinical data were retrospectively analyzed. A total of 167 metallic biliary stents were used in 126 patients. Ninety - two metal stents of mesh type were employed in 70 cases, while 75 metal stents of laser engraving type were adopted in 56 cases. After the treatment all patients were followed up, and the stent patency time as well as the median survival time was determined. The results were analyzed and compared between the two types of stents. Results Technical success rate was 100% (126/126). The median patency rate time of mesh type and laser type was 182 days and 196 days respectively, the patient’s median survival time of mesh type group and laser type group was 179 days and 186 days respectively. No statistically significant differences in the stent patency time and in the median survival time existed between the two groups (P > 0.05). Conclusion In treating malignant biliary obstruction with stenting, the mesh type stent and the laser type stent have quite same therapeutic effect. Therefore, in clinical practice the two types of stent can be replaced with each other to a certain degree.

PurposeTo study the characteristics of contingent negative variation (CNV) in vascular dementia.MethodsCNV was tested and compared in 24 vascular dementia (VD) patients and 22 normal aged persons. Results The data showed that in compare with normal controls the latencies of early component and late component of CNV in VD were greatly prolonged and closely correlated to the extent of dementia. The amplitude of early component was greatly reduced. The reactive time (RT) was prolonged prominently and also correlated with the extent of dementia. The occurrence of postimperative negative variation (PINV) increased. Conclusions The value of CNV can be used to reflect the extent of dementia. Test the CNV in series may help to evaluate the cognitive impairment in VD.
