Objective:To obtain the normal values of the facial soft tissue measurements of the attractive Uygur females in Xinjiang by photogrammetric analysis,and to study the relationship between the facial feature of attractive Uygur females and the neoclassical canons. Methods:31 attractive Uygur women were selected, standardized and referenced frontal photographs of faces were taken,and 14 standard anthropometric marks were determined,then measurements were performed by photoshopCS software.Results:Intercanthal width was rather smaller than nose width and larger than eye fissure width;nose width occupied more than 1/4 of face width or 2/3 of mouth width.The chin occupied 2/3 of the entire mandibular height.There was positive correlation among many horizontal and vertical facial soft tissue measurements.Conclusion:The facial features of the attractive Uygur females in Xinjiang fit the classical facial canons to some extent. There is pertinence in attractive facial form and features.

OBJECTIVETo explore the effect and mechanism of hirudin on atherosclerotic plaques in apolipoprotein E knockout (ApoE(-/-)) mice.

METHODSTotally 24 ApoE(-/-) mice, 7-8 weeks old were fed with high fat diets. They were randomly divided into the recombinant hirudin treatment group (drug group) and the model group according to body weight and different dens, 12 in each group. Twelve C57BL/6J mice, 7-8 weeks old fed with high fat diet were recruited as the normal control group. Recombinant hirudin (0.25 mg/kg) was intraperitoneally injected to mice in the drug group from the 10th week old once every other day for five successive weeks. Equal volume of normal saline was injected to mice in the model group. Mice in the normal control group received no treatment. All mice were sacrificed after fed with high fat diet until they were 20 weeks old. Serum levels of total cholesterol (TC), triglyceride (TG), low-density lipoprotein (LDL), high-density lipoprotein (HDL), high-sensitive C-reactive protein (hs-CRP), E-selectin, interleukin-6 (IL-6), and stromal metalloproteinase-2 (MMP-2) were detected. The plaque/lumen area and extracellular lipid composition/ plaque area were analyzed by HE staining and morphometry. Changes of signaling molecules in store-operated calcium channels, including stromal interacting molecule 1 (STIM1), Orail protein, and transient receptor potential channel 1 (TRPC1) were determined by Western blot. Results Lipid plaque formed in the aorta vessel wall of 20-week old mice in the model group. Compared with the normal control group, serum levels of TC, TG and LDL increased (P<0.01), hs-CRP, E-selction, IL-6, and MMP-2 obviously increased (P<0.01, P<0.05) in the model group; expression levels of STIM1, TRPC1, and Orail significantly increased (P<0.01). Compared with the model group, the plaque/lumen area and the extracellular lipid composition/plaque area significantly decreased in the drug group (P<0.05, P<0.01); serum levels of TC and LDL, hs-CRP, E-selction, IL-6, and MMP-2 obviously decreased (P<0.05, P<0.01); expression levels of STIM1, TRPC1, and Orail were significantly down-regulated (P<0.05, P<0.01).

CONCLUSIONHirudin could significantly improve lipids and endothelial functions of ApoE(-/-) mice, down-regulate expression levels of STIM1, Orai1, and TRPC1, and thus delaying the occurrence and development of atherosclerosis.

Since human society entered the 21st century, the rapid development of medical technology also gave birth to a series of negative effects:medical service technology first, trust crisis of the doctor-patient relation-ship, and medical industry money worship. Especially in recent years, due to the lack of humanistic spirit in medi-cal institutions, the doctor -patient relationship is of the worst state in the history. Therefore, it is urgent to strengthen the medical humanities education in the construction of hospital culture. Aiming at the problems existing in the current medical industry, this paper expounds the importance of strengthening the humanistic education in the construction of hospital culture.

Objective To evaluate the effect of video- assisted thoracoscopic pulmonary segmentectomy in patients with isolated pulmonary arteriovenous fistula (PAVF). Methods A retrospective analysis was performed on 10 patients with PAVF in the department of thoracic surgery of the first affiliated hospital of Nanjing Medical University between January 2010 and December 2016. Computed tomography angiography (CTA) and three-dimensional reconstruction were performed before operation, and all patients accepted video-assisted thoracoscopic pulmonary segmentectomy. Results The diagnosis of PAVF was identified by CTA, with maximum diameter of tumor of 3.0- 5.0 cm. No perioperative mortality or postoperative complications were observed including bleeding, hemoptysis, serious air leakage, and bronchopleural fistula. The lesions were completely removed in all 10 patients, and no patients converted to open surgery intraoperatively. Blood gas analysis showed that oxygen partial pressure before operation, in the first day after operation and the third month after operation was (62.5 ± 6.7), (70.2 ± 4.8) and (75.4 ± 4.8) mmHg (1 mmHg = 0.133kPa) respectively; which was significantly increased successively (P<0.05). After a follow-up time of 3-30 months, no recurrences were observed. Conclusions Video- assisted thoracoscopic pulmonary segmentectomy guided by preoperative CTA and three-dimensional reconstruction is a very effective method for the treatment of isolated PAVF.

Objective To investigate the clinicopathological characteristics and postoperative prognosis analysis of intra-thoracic localized Castleman disease (LCD).Methods The clinical data of 9 patients with intra-thoracic LCD who accepted surgical treatment were retrospectively analyzed.There were 5 males and 4 females,with age of (32.8 ± 10.9) years.Two patients complained of chest pain,1 patient suffered from paraneoplastic pemphigus,and the rest were diagnosed by physical examination.Four cases were diagnosed with LCD by preoperative CT examination.Results All patients underwent surgical resection.Four patients were performed open surgery and 5 patients had video assisted thoracic surgery.All patients accepted radical surgery.But 2 of these patients had postoperative complications.One patient was the injury of phrenic nerve and another was pericardial effusion.Patho-histological showed hyaline vascular type of Catleman disease in all patients.All patients survived without recurrence during the follow-up for 2-53 months.Conclusions Intra-thoracic is rare and liable to misdiagnosed.For increasing the preoperative diagnosis rate of LCD,the combined application of imaging tests is important,and clinicians and radiologists should also enhance the awareness of this disease.Complete surgical resection of the tumor is the best therapeutic alternative for intra-thoracic LCD.
