Objective:Three-dimensional (3D) ultrasound (US) is increasingly being introduced in the clinic,both for diagnostics and image guidance.Although dedicated 3D US probes exist,because of its expensive cost,3D US can also be acquired with the still frequently used two-dimensional (2D) US probes.Methods:Obtaining 3D volumes with 2D US probes is a two-step process.First,a positioning sensor must be attached to the probe for 2D image matching;second,a reconstruction of a 3D volume can be performed into a regular voxel grid.Results:This paper presents a way to realize the 3D US in irled-based Image Guided Radiotherapy using a homemade 2D US.Conclusions:The experiments demonstrate a method of saving costs and having advantages in clinic application.

Objective To investigate the clinical, electrophysiological and pathological features of critical illness polyneuropathy and myopathy (CIPNM). Methods The clinical outcomes, electromyogram Results as well as pathological features in nerves and muscles of 3 patients with CIPNM were investigated and analyzed. Results 3 patients were all provided with assisted respiration after tracheal intubation. 7~10 d after intubation, all the patients emerged muscle strength and tendon reflexes of extremities weakening; while 14 days after that, 2 patients appeared amyotrophy of extremities. Electromyogram showed that the conduction of many motor and sensory nerves for extremities decreased, while the amplitude of compound muscle action potential (CMAP) of part of motor nerves decreased. Biopsy for nerves revealed decreased medullated nerve fibers and regeneration phenomenon of auxiliary fibers; while that for muscles showed neuralgic damage and myopathy-like changes. Conclusion CIPNM can complicate after tracheal intubation. The electrophysiological and pathological examinations for nerves and muscles can be helpful for the diagnosis.

The average life expectancy in Macau is ranking the second in the world, the consumption of fresh medicinal plants is a profound culture in Macau. The paper focus on the distribution of the antioxidant herbs, a comprehensive investigation and analysis the amount of the plant resources was carried out. The antioxidant activity of alcohol extracts was determined by using the DPPH method, and six kinds fresh herbs with high antioxidant free radical activity were screened out. Reference to adult daily dose of vitamin C, it is calculated that the daily dose amount of fresh herbs is less than 200 g. For the expected shortage of resources and the ecological status of Macau, we give some suggestions of herbal introduction in population ecology reconstruction.

OBJCETIVETo investigate the method of separation of culture of bone microvascular endothelial cells (BMECs) of human femoral head in vitro.
METHODSFrom October 2013 to January 2014,15 femoral heads without pathologic change from patients resected during hip replacement were selected involving 2 males and 13 females with a mean age of 71.2 years old ranging from 38 to 92. Cancellous bone in femoral head was bited into broken bone grain and transfered into medium in aseptic contidion. Cells were isolated by the methods of enzymic digestion and density gradient centrifugation,purified by differiential attachment. The characteristics of cells was observed by inverted microscope. vWF and CD31 immunofluorescence analysis was applied for identification of cells.
RESULTSThe number of cells was positively correlated with patients' age after 24 hours in primary culture. The older patients had the less cells numbered. After 4 to 5 days' culture, primary cells appeared short spindle,polygon shaped and cobblestone-like morphology. After 7 to 10 days' culture, primary cells proliferated densely, became fusion, arranged in swirl, and contact inhibition appeared significantly. Immunofluorescence staining revealed the cells were 100% positive for vWF and CD31, and it showed that the cultured cells were BMECs.
CONCLUSIONIt was a simple, steady, effective method with good reproducibility, by which highly purified human BMECs can be obtained.

OBJECTIVETo investigate the clinical effect of mild warming moxibustion (MWM) on acupoints Shenque (RN8) and Guanyuan (RN4) for treatment of recurrent respiratory tract infection (RRTI) in children with cerebral palsy (CP).
METHODSSixty-four CP patients with RRTI were randomly and equally assigned to two groups, all received conventional rehabilitation treatment, but in acute infection stage, MWM was applied on the treated group, and intravenous dripping of immunoglobulin was given to the control group, all for 3 months. The frequency of RRTI attacking (Fre), the mean cough alleviating time (T-CA) and rale disappearing time (T-RA) during infection, as well as the serum levels of immune globulins during the post-treatment 1-year follow-up period were observed.
RESULTSThe effectiveness in the treated group was better than that in the control group, showing in aspects of Fre (2.38 +/- 0.64 times vs. 6.50 +/- 0.84 times), T-CA (3.92 +/- 1.32 days vs. 6.48 +/- 2.18 days) and T-RA (4.66 +/- 1.82 days vs. 7.64 +/- 1.44 days), significant difference was shown between groups (P < 0.01). The serum levels of IgG, IgM and IgA all raised in both two groups (P < 0.05), comparison of immunoglobulin levels between groups showed that they were lower immediately after treatment, but higher at the end of the 1-year follow-up in the treated group than those in the control group.
CONCLUSIONMWM on acupoints Shengue and Guanyuan has a better and long-term clinical effect for treatment of RRTI in children with CP.

9.Diagnostic values of X-ray and CT examinations for traumatic diaphragmatic rupture
Chinese Medical Equipment Journal 2017;38(11):72-74,93
Objective To explore the diagnostic values of X-ray and CT examinations for the traumatic diaphragmatic rupture. Methods Totally 17 patients with traumatic diaphragmatic rupture were retrospectively analyzed, who underwent X-ray chest radiograph and 64-slice spiral CT examinations as well as coronal and sagittal imaging by multi-planar reconstruction with GE ADW 4.6 workstation. Results Of the 17 patients, there were 15 ones had the rupture occurred on the left side (93.7%), one case on the right side (6.3%) and the remained one had no diaphragmatic injury;there were 10 ones of diaphragmatic contour discontinuity, 6 ones of intrathoracic hernia, 2 ones of cervical stenosis, one case of hanging sign and two cases of falling viscera sign. Conclusion Routine chest X-ray radiography has difficulty in diagnosing diaphragmatic rupture, while CT multiplanar imaging contributes to determining traumatic diaphragmatic rupture. Diaphragmatic rupture may occur after multiple trauma, and CT with multiplanar reformations has to be used as the routine examination for diagnosing diaphragmatic rupture.

?AlM:To explore the influence factors of orthokeratology controlling development of juvenile myopia.
?Methods: A retrospective analysis of 86 cases ( 169 eyes ) who performed orthokeratology from November 2012 to November 2013 in our hospital was carried out. Ater 2a treatment, diopter increased > -0. 25D as invalid control group (54 eyes), diopter increased ≤ -0. 25D as effective control group ( 115 eyes ) . The difference of various factors between two groups were compared.
?RESULTS: Univariate comparison showed that the two groups had no statistical significance (P>0. 05) in terms of gender, whether wear glasses in the past, anterior corneal diameter before treatment, central corneal thickness, intraocular pressure and anterior chamber depth. However, the two groups had statistical significance (P<0. 05) in the terms of age, dioptre before trement, corneal curvature, and axial length basis. Logistic regression analysis showed that foundation axial length, age and corneal curvature were in line with regression model ( P<0. 05 ), these were independent factors that orthokeratology lens control juvenile myopia development.
? CONCLUSlON: lndependent factors affecting orthokeratology control juvenile myopia development is foundation axial length, age and corneal curvature. For juvenile patients, the longer of foundation axial length, the longer the age, the greater the curvature of cornea, orthokeratology can better control the myopia’s development.
