BACKGROUND:Based on the integration of virtual reality technology with acupoints, acupuncture can be expressed three-dimensional y.
OBJECTIVE:To explore the structure of points through reconstructing digitalized three-dimensional visualization of Neiguan (PC6) structure based on VOXEL-MAN and Micro-XCT.
METHODS:Muscles and other tissues adjacent with Neiguan (PC6) were segmented and merged based on the VOXEL-MAN system combined with the anatomical knowledge of acupoints;nerves and blood vessels were performed with three-dimensional reconstruction;the needle-inserting animation of Neiguan (PC6) was obtained by running script file. Three-dimensional visualization and virtual needle-inserting researches of Neiguan (PC6) were performed. Nature of the acupoints was detected by the Micro-XCT-200 machine additional y.
RESULTS AND CONCLUSION:The visualization of the anatomical structure of local Neiguan (PC6) was completed, and the localization and expression of Neiguan (PC6) in the digitized virtual human were realized. The Neiguan (PC6) structure was researched with Micro-XCT-200, and showed there was no new tissue. Local three-dimensional reconstruction of the acupoint structure could help to display the anatomical structure of acupoints and simulate the acupuncture process. It could also help to observe the relationship between the needle body and the surrounding tissues during needle-inserting, which supplying a good basis not only for exploring the security of needle-inserting, but also for improving the clinical effect of acupuncture. The research on the structure of acupoint Neiguan (PC6) by Micro-XCT-200 provides further experimental evidence for the hypothesis of three-dimensional acupoint.

OBJECTIVE:
To evaluate the inhibitive effect of matrine modification X on the growth of human nasopharyngeal carcinoma CNE2 cell xenografts in nude mice.
METHOD:
Tumor model was established by subcutaneous inoculation of nasopharyngeal carcinoma cell CNE2 into nude mice, which was used to evaluate the antitumor effect of matrine modification X in vivo. The expression levels of Bax, Bcl-2, Caspase3 were detected by real-time PCR and western blot.
RESULT:
The growth of xenografts in nude mice was significantly suppressed after application of matrine modification X in a dose-dependent manner. The inhibition rates were 32.55% and 44.89% when treated at medium and high dose respectively. Real-time fluorescence quantitative-PCR and Western Blot results showed that the expression of Bax and Caspase3 increased, while the expression of Bcl-2 decreased in a dose-dependent manner. The change of high dose group was obvious, and the difference was statistically significant (P < 0.05).
CONCLUSION
Matrine modification X could significantly inhibit the growth of human nasopharyngeal carcinoma CNE2 cell xenografts in nude mice, probably by inducing the apoptosis of nasopharyngeal carcinoma cells, and the possible mechanism is related to regulating the expression level of Bax/Bcl-2 and Casepase3.

OBJECTIVETo summarize the imaging features of urinary dysfunction associated with ketamine abuse (KAUD) for imaging diagnosis of KAUD.
METHODSWe analyzed the imaging findings in 45 patients with KAUD, all having a history of ketamine abuse and presenting with severe lower urinary tract symptoms. The patients underwent imaging examinations with ultrasonography (n=45), X-ray (n=38), computed tomography (n=28), magnetic resonance imaging (n=10) or single photon emission computed tomography (n=25), and the results were classified and evaluated to identify the common imaging findings.
RESULTSThe imaging changes of KAUD were found primarily in the urinary and biliary system. The most common imaging characteristics included thickening of the bladder wall, contracture and decreased functional volume of the bladder, dilation of the ureter and hydronephrosis, stricture of the upper ureter, renal impairment, dilation of the biliary system, and inflammation or swelling of the adjacent organs and lymph nodes
CONCLUSIONKAUD presents with typical imaging changes. Radiologists should be aware of KAUD if the typical imaging features are detected, especially in cases with a history of ketamine abuse.

OBJECTIVE:
To summarize our experience of successful and failed management in 8 huge lobulated nasopharyngeal angiofibromas with intracranial extensions, and introduce some key points of perioperative treatments.
METHOD:
Eight male case with an average age of 18 years, were all lobes extending into middle and/or anterior cranial fossa, in which 5 cases revealed blood supply from the internal carotid arteries and 3 cases were reoperated because of recurrence. Preoperatively, the tumor were evaluated by CT, CTA, MRI and/or MRA, and super selective embolization of the feeding arteries were crucial procedures. The combined craniofacial approaches were used to excise these tumors.
RESULT:
Five cases were removed completely, and 3 cases were removed partly in which 2 were due to serious bleeding caused by lack of DSA technique at that time and 1 were due to neglecting the tumor lobe in the sphenoid sinus of the other side.
CONCLUSION
Reasonable perioperative management are very important for control of intra-operative blood loss, complete remodeling of the tumor and avoiding complication.

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.
