Journal of Practical Medicine 2004;483(7):33-35
From December 2000 to March 2003, at Huu Nghi Hospital, 85 patients with endotracheal intubation were studied. Before making the examine of weaning from mechanical ventilation: There were no difference at the age, the predicted body mass, the duration of artificial ventilation between 2 groups of patients. The indices of f, Vt, VE, f/Vt were measured by EVITA breathing machine in the 5th minute after assisted ventilation of PS = 7cmH2O. No high values of predicting the weaning from mechanical ventilation of Vt, VE in the 5th minute were notified. The indices of Cst, Cdyn, R, PEEP measured by EVITA machine did not give predicted values for weaning from machanical ventilation.

Objective To investigate the differences of heart mass and lung mass in forensic autopsy cases and to explore their application value in forensic identification. Methods The data from 1 614 autopsy cases accepted by center of Medico-legal Investigation of China Medical University between 2007 to 2016 were collected. The correlation of heart and lung mass with age, height, body weight, and body mass index (BMI), as well as differences in different causes of death were analyzed by GraphPad Prism 6.0 software. Results The heart mass and lung mass of males were higher than those of females (P<0.05). The heart mass of males and females was positively correlated with age, height, body weight and body mass index (BMI) (P<0.05). The heart mass of patients dying from sudden cardiac death (SCD) was significantly higher than those dying from other causes of death. The lung mass of patients dying from drowning and delayed treatment was higher than those dying from other causes of death (P<0.05). Conclusion In forensic practice, measurement of the heart mass and lung mass has certain significance for differential diagnosis and diagnosis of different causes of death.

Super-resolution image reconstruction techniques play an important role for improving image resolution of lung 4D-CT. We presents a super-resolution approach based on fast sub-pixel motion estimation to reconstruct lung 4D-CT images. A fast sub-pixel motion estimation method was used to estimate the deformation fields between "frames", and then iterative back projection (IBP) algorithm was employed to reconstruct high-resolution images. Experimental results showed that compared with traditional interpolation method and super-resolution reconstruction algorithm based on full search motion estimation, the proposed method produced clearer images with significantly enhanced image structure details and reduced time for computation.

The bronchoarterial (BA) ratio measured with computed tomography is widely used in human medicine to diagnose bronchial dilation or collapse. Although use of the BA ratio in veterinary medicine has been recently studied, this has not been evaluated in brachycephalic dogs predisposed to bronchial diseases including bronchial collapse. The purpose of this study was to establish BA ratios for brachycephalic dogs and compare the values with those of non-brachycephalic dogs. Twenty-three brachycephalic dogs and 15 non-brachycephalic dogs without clinical pulmonary disease were evaluated. The BA ratio of the lobar bronchi in the left and right cranial as well as the right middle, left, and right caudal lung lobes was measured. No significant difference in mean BA ratio was observed between lung lobes or the individual animals (p = 0.148). The mean BA ratio was 1.08 +/- 0.10 (99% CI = 0.98~1.18) for brachycephalic dogs and 1.51 +/- 0.05 (99% CI = 1.46~1.56) for the non-brachycephalic group. There was a significant difference between the mean BA ratios of the brachycephalic and non-brachycephalic groups (p = 0.00). Defining the normal limit of the BA ratio for brachycephalic breeds may be helpful for diagnosing bronchial disease in brachycephalic dogs.

OBJECTIVETo explore distribution of the Liver and Lung Channels in the brain so as to provide imaging basis for construction of channel theory in the brain.
METHODSSixty healthy student volunteers were randomly divided into a Liver Channel group (I) and a Lung Channel group (II), and the each group was further divided into five subgroups with 6 volunteers in each subgroup, based on five-shu-point principles which, were Dadun (LR 1, I 1), Xingjian (LR 2, I 2), Taichong (LR 3, I 3), Zhongfeng (LR 4, I 4), Ququan (LR 8, I 5), Shaoshang (LU 11, II 1), Yuji (LU 10, II 2), Taiyuan (LU 9, II 3), Jingqu (LU 8, II 4), and Chize (LU 5, II 5), respectively. In order to observe the brain activating patterns during acupuncture at the different acupoints, functional magnetic resonance imaging (fMRI) technique was adopted. All image data were then analyzed with SPM 2 software. The statistical parameter gram was composed of the pixel P < 0.01, and anatomic location was made according to Talairach coordinate, attaining experimentally activated areas, and the commonly activated area of five-shu-point of each channel was considered as the brain distribution of the Liver and Lung Channels.
RESULTSThe common areas activated by the five-shu-points of the Liver Channel were homolateral Brodmann area (BA) 34, BA 47, red nucleus, contralateral BA 19, BA 30, BA 39, the superior parietal lobule, cerebellum decline, and bilateral BA 3 and culmen. The common areas activated by the five-shu-points of the Lung Channels included homolateral BA 2, BA 18, BA 35, and contralateral BA 9 and substania nigra.
CONCLUSIONThere are relatively specific corresponding brain areas for the Liver and Lung Channels, indicating that there is possible relatively specific connection between channels and the brain.

Micropigs are the most likely source animals for xenotransplantation. However, an appropriate method for evaluating the lung of micropigs had not been established. Therefore, this study was performed to evaluate the feasibility of 64-channel multi-detector row computed tomography (MDCT) to measure the diameter of the pulmonary arteries and the lung volume in micropigs. The mean diameters of the trachea, and left and right bronchi were 1.6 +/- 0.17, 1.18 +/- 0.14, and 1.1 +/- 0.11 cm, respectively. The mean diameters of the main, right, and left pulmonary arteries were 1.38 +/- 0.09, 1.07 +/- 0.26, and 0.98 +/- 0.13 cm and the diameters of right, left, and common inferior pulmonary veins were 0.97 +/- 0.20, 0.76 +/- 0.20, and 1.99 +/- 0.26 cm, respectively. The mean lung volume was 820.3 +/- 77.11 mL. The data presented in this study suggest that the MDCT may be a noninvasive, rapid, and accurate investigational method for pulmonary anatomy in living lung donors.

9.Occurrence of the lung fluke, Paragonimus heterotremus in Manipur, India.
Chinese Medical Sciences Journal 2003;18(1):20-25
OBJECTIVESTo determine the natural crustacean host, the Paragonimus species, and to investigate the potential host-parasite relationship between Manipur Paragonimus and some of the laboratory animals.
METHODSThe laboratory animals such as puppies, albino rats and Swiss mice were infected orally with metacercariae isolated from the fresh water crabs, Potamiscus manipurensis. The fecal specimens of the experimentally infected animals were examined microscopically for Paragonimus eggs at regular intervals. The animals were autopsied on days 35 to approximately 328 after infection and the isolated worms were flattened between glass slides and fixed in 70% alcohol. The worms were stained with carmine and mounted with Canada balsam for morphological studies. The eggs were collected in 5% formol saline solution for microscopy. The flukes were classified into 4 developmental stages.
RESULTSA total of 11 worms, 5 mature, 5 immature and 1 pre-adult were recovered. The morphological features of the metacercariae, worms and eggs were similar to those of Paragonimus heterotremus.
CONCLUSIONManipur is one of the rare areas in the world where Paragonimus heterotremus is prevalent and the puppies are ideal experimental animal host. This species may be one of the important causes of paragonimiasis in animals and humans in Manipur.

We aimed to compare the CT findings of nontuberculous mycobacterial pulmonary diseases caused by Mycobacterium avium-intracellulare complex (MAC) and Mycobacterium abscessus. Two chest radiologists analyzed retrospectively the thin-section CT findings of 51 patients with MAC and 36 with M. abscessus infection in terms of patterns and forms of lung lesions. No significant difference was found between MAC and M. abscessus infection in the presence of small nodules, tree-in-bud pattern, and bronchiectasis. However, lobar volume decrease (p=0.001), nodule (p=0.018), airspace consolidation (p=0.047) and thin-walled cavity (p=0.009) were more frequently observed in MAC infection. The upper lobe cavitary form was more frequent in the MAC (19 of 51 patients, 37%) group than M. abscessus (5 of 36, 14%) (p=0.029), whereas the nodular bronchiectatic form was more frequent in the M. abscessus group ([29 of 36, 81%] vs. [27 of 51, 53%] in MAC) (p=0.012). In conclusion, there is considerable overlap in common CT findings of MAC and M. abscessus pulmonary infection; however, lobar volume loss, nodule, airspace consolidation, and thin-walled cavity are more frequently seen in MAC than M. abscessus infection.
