In order to improve the efficacy of vibration expectoration and prevent secondary injury in patients with chest trauma,the body surface marking method was used in vibration expectoration.The exact injured locations and areas were identified via CT ot X-ray results.Then,the restricted and focused areas of expectoration were marked with red and green colors,which could guide the machines to avoid the fracture sites,reduce pain,prevent secondary injury and administrate effective expectoration in the areas of sputum and atelectasis.However,the dynamic CT or X-ray results must be used for reference to ensure the accuracy of the body surface marking.

Objective To investigate the expressions of thymidylate synthase (TS) and adenosine triphosphate (ATP)-binding cassette superfamily G member 2 (ABCG2) in advanced gastric cancer (GC) and to explore their correlation with clinical pathological features.Methods A total of 80surgical specimens of advanced gastric cancer patients were collected.The expressions of TS and ABCG2 in gastric cancer tissues and adjacent normal gastric tissues were detected by immunohistochemical method.The expression of P-glycoprotein in gastric cancer tissues was also examined.The correlations between TS,ABCG2 and clinical pathological features and P-glycoprotein were analyzed.Chi-square test was performed for two groups comparison and Kruskal-Wallis H test were used for multi-groups comparison.Results The positive rates of both TS and ABCG2 in gastric cancer tissues [85.0％ (68/80) and 90.0％ (72/80)] were higher than those of adjacent normal gastric tissues [62.5 ％ (50/80) and 78.7 ％ (63/80)],the differences were statistically significant (x2 =11.466 and 16.463,P=0.009 and 0.001).There were close correlation between the expression of TS,ABCG2 and tumor TNM stage,differentiation status,invasion depth (TS:x2 =30.686,61.470 and 40.545 ; ABCG2:x2=48.192,63.150 and 47.512; all P＜0.01).The later the tumor staged,the worse the cells differentiated and the deeper the tumor invaded,the higher level they expressed.Both TS and ABCG2expressions in gastric cancer tissues were correlated with the expression level of P glycoprotein (x2 =43.977and 29.509,both P＜0.01).Conclusion TS and ABCG2 may be potential indexes to predict the degree of malignancy,progression,drug resistance and prognosis in gastric cancer.

Objective To study the imaging of inner ear malformations in children with congenital sensorineural hearing loss(SNHL).Methods CT and MRI examinations were performed on children with SNHL diagnosed by audiological test.One hundred and eighty-eight patients with complete imaging information were obtained.The imaging of inner ear malformations was analyzed according to Sennaroglu's classification. Results Thirty-five patients(54 ears) were found with inner ear malformations by CT and MRI,3 of whom(5 ears) were accompanied by outer and middle ear malformations.Among the 35 patients,2(4 ears) were found to be common cavity deformity,1(1 ear) cochlear hypoplasia,13(26 ears) incomplete partition II(Mondini deformity),4(7 ears) vestibule dilation,13(19 ears) semicircular canal deformity and 19(34 ears) large vestibular aqueduct.Internal auditory canal was found narrow in 7 patients(10 ears) and wide in 1(2 ears) with classic Mondini deformity. Conclusion CT and MRI examinations are of great importance to the diagnosis and treatment of inner ear malformations in children with congenital SNHL,especially for the candidates of cochlear implantation.

OBJECTIVETo investigate the morphological features of the perforator from the first plantar metatarsal artery, so as to provide anatomic basis for the reconstruction of soft-tissue defects of the forefoot.

METHODSThe first metatarsophalangeal joint was chosen as the landmark on 30 human cadaveric feet prefused with red latex. The following contents were observed under surgical magnifier: (1)The origin, courses,branches,distribution of the perforator of the first plantar metatarsal artery; (2)The anastomoses among the perforator of the first plantar metatarsal artery and other arteries on the medial aspect of the foot. Simulated operation was performed on one fresh specimen.

RESULTSThe perforator of the first plantar metatarsal artery passed through the space between the tendon, the abductor hallucis and the first metatarsal bone, and its entry point into the deep fascia was located (2. 3 ± 0.7 ) cm proximal to the first metatarsophalangeal joint. The perforator anastomosed with either the medial tarsal artery, the medial anterior malleolus artery or the branch of the medial plantar artery on the superior margin of the abductor hallucis, forming a longitudinal arterial chain,through which small branches were given off to the skin of the medial aspect of the foot. The perforator was( 1. 1 ± 0.2) mm in diameter and(3.2 ± 0.2) cm in length.

CONCLUSIONThe flap based on the perforator of the first plantar metatarsal artery can be harvested as an axial flap to repair the defects of soft tissue on the forefoot.

OBJECTIVETo explore effects of Shenqi preparation,Traditional Chinese Medicine, on anti-fatigue and anti-oxidant functions.

METHODSOne hundred and twenty mice were randomly divided into control group and 3 experimental groups. The high, medium and low-dose of Shenqi preparation were given to the 3 experimental groups respectively, while distilled water to the control group for 15 d. The loaded swimming time, the level of lactate, serum urea nitrogen (SUN), muscle and liver glycogen, liver super-oxide dismutase (SOD), the content of malondialdehyde (MDA), glutathione peroxidase(GSH-Px) were assayed.

RESULTSThe loaded swimming test showed that the exhausted swimming time of 3 experimental groups [(296.0 +/- 25.3)s, (437.0 ĝ 38.9)s, (595.0 +/- 53.9)s respectively] was longer than that of control group [(231.0 +/- 22.5)s, P < 0.05, P < 0.01]. The liver glycogen content of the high and medium-dose experimental groups were higher than that of control group respectively (P < 0.01). The SUN content of each experimental group was less than that of the control group (P < 0.01, P < 0.05). Moreover,in the medium and high dose experimental groups, less accumulation of lactate was found (P < 0.01, P < 0.05), and the content of liver SOD and GSH-Px was higher (P < 0.01, P < 0.05). The content of liver MDA in high-dose experimental group was less than that of the control group (P < 0.05).

CONCLUSIONShenqi preparation, especially the high and medium-dose experimental groups, is able to improve exercise tolerance and has anti-fatigue and anti-oxidant effects in mice.
