Superficial temporal fascia,which has various names,such as temporal fascia,temporoparietal fascia,epicranial aponeurosis and galeal extension,has been used to define the fascial layers of the temporal region.All these different names reflect an anatomical feature of the related fascia.This region exists superficial temporal vessels,the temporal branch of the facial nerve and the auriculotemporal nerve,so is very important in otoplasty.This paper reviews the progress of superficial temporal fascia application in otoplasty.

Objectives To investigate the proliferation and apoptosis of smooth muscle cells(SMCs) after implantation of NiTi radioactive stents. Methods Radioactive and nonradioactive stents were implanted in abdominal aortas of 76 rabbits.The proliferation and apoptosis of SMCs were observed using immunohistochemistry and TUNEL.Results (1) Neointima areas on radioactive stents were less than those on nonradioacvtive stents at 1-month and 3-month respectively (P0 05).(2)The expressions of PCNA were lower in radioactive stent groups at different times compared with those of controls(P0.05).Conclusions (1) Radioactive stents can reduce the neointima areas on the implanted stents.(2)Radioactive stents can inhibit the proliferation of SMCs.(3)Radioactive stents promote the apoptosis of SMCs.

Neovascular glaucoma is a rare and severe complication of hypoperfusion retinopathy.The appearance of hypoperfu- sion retinopathy complicating neovascular glaucoma in ophthalmolscopy and fundus fluorescein angiography shows a special feature. Neovascular glaucoma occurs when new fibrovascular tissues proliferate onto the chamber angle and obstruct the trabecular meshwork. The stenosis or occlusion of internal carotid artery is the most common reason of hypoperfusion retinopathy in elder people.Early recog- nition and treatment of patients with carotid occlusive diseases may prevent more serious complications.

OBJECTIVE: To establish a rapid molecular identification method for Polygonatum filipe species. METHODS: Polymorphism analysis on DNA of P. filipe and P. cyrtonema was performed by using inter simple sequence repeat (ISSR) and sequence-related amplified polymorphism (SRAP) molecular markers. Differential ISSR and SRAP bands between the two species were sequenced and species-specific sequence characterized amplified region (SCAR) primers were designed for the identification of P. filipe and P. cyrtonema. RESULTS: Under respective optimal annealing temperature, three pairs of SCAR primers can specifically amplify three fragments of 150, 354 and 518 bp only from P. filipe, respectively, not from P. cyrtonema. The SCAR-PCR test was simple and convinent to operate, and reproducible. The molecular identification technology based on SCAR markers was further validated by testing 8 samples of Polygonatum tubes sold in market. CONCLUSION: SCAR molecular technology developed in this study can be used for the assistant identification of P. filipe species.

Background It has not been reported that if the visual cortex M receptor changed during the development of myopia and how it changed if given acupuncture treatment.Objective The aim of this study was to observe the effect of electroacupuncture stimulation on the expression of acetylcholine receptors M1 (AchRM1) in visual cortex of guinea with lens-induced myopia (LIM).Methods Forty-eight three-week-old healthy guinea pigs were randomized into the normal control group,the LIM model group and the LIM electroacupuncture group.The right eyes of the guinea pigs were selected as the experimental eyes.LIM was created by monocularly wearing of-10 D lens for 4 weeks in the right eyes in the LIM model group and LIM electroacupuncture group,and then the acupuncture at the temple and hegu point was performed for 30 minutes per day for consequent 4 weeks,in the LIM electroacupuncture group.The fellow eyes of the guinea pigs were used as the self-control eyes.The refractive power and axial length were examined with retinoscopy and A-type sonography before and 4 weeks after modeling,respectively.The animals were sacrificed by excessive anesthesia at the fourth week after acupuncture and visual vertex tissue was obtained.The expression of M1 receptor mRNA in visual vertex was detected by fluorescence quantitative PCR,and the content of M1 receptor protein in visual vertex was assyed by ELISA.The study protocal was approved by Animal Ethic Committee of Shandong University of Traditional Chinese Medicine,and the use and care complied with Statement of the Association for Research in Vision and Ophthalmology.Results At the fourth week after modeling,the mean diopters were (-3.24±0.28) D and (-3.30±0.45) D in the LIM model group and the LIM eleetroacupuncture group,which were significantly higher than (0.83 ±0.86)D in the normal control group (both at P=0.000),and there was no significant difference in the diopter between the LIM model group and the LIM electroacupuncture group (t =0.200,P =0.659).The mean axial lengths were (8.67 ±0.14) mm and (8.60±0.06) mm in the LIM model group and the LIM electroacupuncture group,which were considerably increased in comparison with (8.33±0.08)mm in the normal control group (both at P＜0.05).The relative expression levels of AchRM1 mRNA in visual cortex were 0.79±0.18,1.36±0.23 and 1.13±0.13 in the normal control group,LIM model group and LIM electroacupuncture group,and the relative expression level of AchRM1 mRNA in the LIM electroacupuncture group was significantly higher than that of the normal control group and lower than that of the LIM model group (both at P＜0.05).In addition,the contents of AchRM1 receptor protein in the visual cortex were 248.00±33.31,455.17±42.40 and 396.17±47.57 in the normal control group,LIM model group and the LIM electroacupuncture group,with a similar pattern among the groups (both at P＜0.05).Conclusions A electroacupuncture stimmulation do not affect the myopic diopter and axial length in LIM model.The AchRM1 and AchRM1 receptor in the visual cortex up-regulate in LIM eyes,infering that electroacupuncture stimmulation can improve vision by decreasing the level of AchRM1 receptor in visual cortex in LIM eyes in guinea pigs.

Objective The aim of this study was to investigate the understanding and application of the Chinese Urological Association (CUA) guidelines of Benign Prostatic Hyperplasia (BPH) (2011 edition) in Chinese urologists.Methods The survey was conducted between September,2012 and November,2012.Questionnaires designed by the CUA were used to investigate the understanding and management of BPH in CUA-registered urologists,who work in clinic for at least 20 hours per week.Data,including general characteristics of the urologists,understanding of BPH,BPH diagnosing in suspected patients,BPH treatment,and follow up,were collected.7500 questionnaires were distributed.A total of 4 897 participants responded (response rate 70.0％).86 questionnaires with incomplete information and 37 duplicate questionnaires were excluded.And 4 774 validate questionnaires were included for the analysis,finally.The mean age of those investigated urologists was (39.9±9.2) years old.Among them,3 802 (81.0％) urologists work in the tertiary hospital,878 (18.7％) urologists work in the secondary hospital and 12 (0.3％) urologists work in the other hospital.The district distribution in those urologists included 455 (9.6％) in northeast china,812 (17.1％) in north china,1 696 (35.6％) in east china,869 (18.2％) in south china,634 (13.3％) in southwest china,295 (6.2％) in northwest china.1 835 (43.8％) urologists have less than ten years working experience.1 505 (35.9％) urologists have 11 to 20 years working experience.The 21 to 20 years working experience was reported in 705 (16.8％) urologist.And the other 149 (3.5％) urologists have working experience more than 31 years.The educational background in this study included doctor degree in 732 (15.8％) urologists,master degree in 1 729 (37.4％) urologists,bachelor degree in 2 067 (44.7％)urologists and college degree in 101 (2.1％) urologists.The position composition included 834 (18.2) directors,1 371 (30.0％) deputy directors,1 605 (35.1％) attendings and 765 (16.7％) residents.The data were analyzed using rank-sum test,2 test,or Fisher's exact test.Results The understanding of BPH clinical progression and progression-associated risk factors in Chinese urologists was poor.Compared to the guidelines,the rate of consistent were only 43.4％ (2 023/4 665) and 10.2％ (477/4 660),respectively.The initial evaluation methods for suspected BPH patients were in low consistency with the guidelines (20.2％,845/4 181) and were inconsistent among different areas [66.5％ (290/436) in northeast china,64.7％ (556/859) in south china,55.6％ (158/284) in northwest china,55.1％ (922/1 672) in east china,54.7％ (435/795) in north china,48.0％ (296/617) in southwest china].The participants showed poor understanding of the primary goal of treatment for BPH (4.9％ consistent,229/4 666) and the criteria about watchful waiting (22.5％ consistent,1 051/4 674).However,the understanding of surgical indications for BPH was good (94.6％ consistent,4 410/4 663).The therapeutic effects of 5α-reductase inhibitor for BPH were acknowledged by 93.4％ (4 388/4 699) participants.The consistent rate with the guidelines of follow-up examinations was low for patients with watchful waiting (7.8％,355/4 531),medication treatment (8.4％,373/4432),and surgery (44.8％,2 105/4 702).Conclusions The understanding of the CUA BPH guidelines is poor in Chinese urologists.Target training in the specific urologists with tailored contents is necessary.

Objective To compare the effect of 5-fluorouridine(5-FUR) prodrug liposome on the cell proliferation and apoptosis in HEP-2 cells.Methods MTT assay was used to investigate the cell proliferation after 5-FU or 5-FUR prodrug liposome at the dose of 3.0,0.6,0.12 or 0.024 ?g/ml was added into the culture medium of HEP-2 cells for 72 h.Flow cytometry(FCM) was used to measure the cell cycle when the cells were treated with 0.17 ?g/ml 5-FU or 0.05 ?g/ml 5-FUR prodrug liposome for 72 h.The apoptosis of cells treated with 0.05 ?g/ml 5-FU or 5-FUR for 48 h were assayed with FCM.Results The IC50 of 5-FU on HEP-2 cells was 300% higher when compared with 5-FUR prodrug liposome.Treated with 5-FU and 5-FUR prodrug liposome respectively,HEP-2 cell lines were both arrested at S stage.the apoptosis rate of HEP-2 were(10.35?1.33)% and(21.57?0.11)% respectively.Conclusion Compared with 5-FU,5-FUR prodrug liposome inhibits the cell proliferation of HEP-2 cells more significantly,arrests more cells at S phase,and improves cell apoptosis.

Objective:To describe a feasible surgical technique for patients with renal cell carcinoma associated with a supradiaphragmatic tumor thrombus that avoids cardiopulmonary bypass procedure. Methods:We retrospectively analyzed 2 cases with right kidney tumor and tumor thrombus above the dia-phragm treated in April and August,2015.The two patients were both female,aged 73 and 67 years. The tumor sizes of right kidneys were 7.0 cm ×6.3 cm ×5.7 cm and 8.7 cm ×7.0 cm ×5.2 cm,and the tumor thrombuses were 1.3 cm and 1.8 cm above the diaphragm.The second patient had synchro-nous metastasis in right adrenal gland ,and the tumor thrombus arose from the adrenal vein but not the renal vein.Intraoperative transesophageal echocardiography (TEE)was used to assess real-time mobility of the thrombus.A modified chevron incision was used,the right kidney was mobilized laterally and pos-teriorly,and the renal artery was identified,ligated,and divided.The infradiaphragmatic inferior vena cava (IVC)was exposed and isolated by mobilizing the liver off the diaphragm or to the left (piggyback liver mobilization,case 2).The central diaphragm tendon was dissected or incised in the midline until the supradiaphragmatic intrapericardial IVC was identified and gently pulled beneath the diaphragm and into the abdomen.The tumor thrombus was then “milked”downward out of the intrapericardial IVC un-der the guidance of TEE.The distal and proximal IVC to the tumor thrombus,porta hepatis,and left re-nal vein were clamped.Tumor thrombus was removed from the IVC.The IVC was sutured and vascular clamps were placed below the major hepatic veins.Pringle’s maneuver was then released and hepatic blood drainage was permitted during closure of the remaining IVC.Related literature was reviewed.Re-sults:Complete resection was successful through the transabdominal approach without CBP in both pa-tients.Estimated blood loss was 1 500 mL and 2 000 mL,and 1 200 mL and 800 mL of blood were trans-fused.The postoperative courses were uneventful.Both patients subsequently underwent tyrosine-kinase inhibitor therapy.Both patients were alive without tumor recurrence or new metastasis during the follow-up of 6 months and 9 months.Conclusion:In selected cases,renal cell carcinoma extending into the IVC above the diaphragm can be resected without sternotomy,CBP or DHCA.
