Objective To investigate the ultrasound characteristics of prenatal fetus otocephaly . Methods Three prenatal fetus with otocephaly were examined with two -and three-dimensional ultrasoundand examined results were compared with the those of induced labor or autopsy ,and ultrasound characteristicsof prenatal fetus were analyzed and summarized .Results The ultrasound performance of three prenatal fetuswith otocephaly and the examination of the appearance after induced labor showed :(1) The most intuitiveinitial sonographic performance of otocephaly was manifested by the absence of stomach bubble andoverabundance of amniotic fluid.Among three fetus,one fetus had overabundance of amniotic fluid at the midstageof pregnancy,one fetus had normal amniotic fluid at the mid-stage of pregnancy and one fetus hadextremely high amount of amniotic fluid and absence of stomach bubble at late stage of pregnancy .(2) Allthree fetus showed agnathy and synotia (shifts of both ears to the midline) and microstomia deformity.(3) All three fetus had associated complications with deformity in other systems including two cases of patients withcleft lip and palat,both were the fracture unilateral cleft lip derived from small mouth .One fetus withdysmelia and one fetus with complicated cardiovascular deformity and situs inversus and .(4) The results ofexamination after induced labor or autopsy were consistent with those of the prenatal ultrasound examination . Conclusions Prenatal ultrasound examination is an effective and feasible means for the diagnoses ofotocephaly.When the symptoms of “absence of stomach bubble and extremely high amount of amniotic fluid ”occurred,the fetal ear and submaxilla should be examined to confirm stand -alone otocephaly prenatally.

OBJECTIVE:To compare home-made mu'an-eye-gel(acyclovir plus honey) with commercial aciclovir(ACV)-eye-gel in releasing drug characteristics in vitro.METHODS:The in vitro drug release test was conducted by the third method of dissolution determination stated in Chinese Pharmacopeia together with bag filler method.The cumulative drug-releasing percentage and the acyclovir amount in mu'an-eye-gel versus ACV-eye-gel were determined by UV spec-trophotometry,and the accumulative releasing drug percentages of the two preparations were computed and their drug release behaviors w ere compared.RESULTS:The in vitro releasing behaviors of mu'an-eye-gel followed the Weibull kinetic equa-tion,however the vitro releasing behavior of commercial ACV-eye-gel followed the zero order kinetic equation,and the T80%and Q8 h had statistical significances between(mu'an-eye-gel:T80%=3.156?0.013(h),Q8 h=93.28?0.010(%);ACV-eye-gel:T80%=10.16?0.009(h),Q8 h=67.85?0.025(%)) 2 kinds of preparation.CONCLUSION:Mu'an-eye-gel is superior to the commercial ACV ophthalmic gel in both releasing velocity and accumulative drug release percentage.

The research data at home and abroad show that the overall burnout rate of clinical professional graduate students was high. They are vulnerable to burnout because of long duty hours, learn-ing pressure, intense and overloading work and especially the significantly reduced personal accomplish-ment in the situation of the contradiction between doctors and patients in our country. Burnout not only re-sults in psychological distress and physical symptoms, but also has negative effect on the quality of graduate medical education during residency training. Therefore, educators need to develop an active awareness of burnout and ought to perform interventions such as formulating the appropriate learning goals, improving the work efficiency, reducing work hours, positive psychological counseling and stress management training to prevent such occurrences.

Objective: To evaluate the feasibility,the safety and the effect of early postoperative enteral nutrition in patients with esophageal cancer.Methods: On the first postoperative day,40 patients were randomly divided into two groups.One group was given isocaloric total parenteral nutrition through central vein(TPN group) and the other group was fed with enteral nutrition through nasoenteric tubes or jejunostomy tubes which were inserted during the operation(EEN group).All variables were measured before operation and on postoperative day 1 and 8.Blood was drawn at different time points to assess albumin,prealbumin and transferrin.Immune response was determined by immunoglobins,total lymphocytes,T-lymphocyte subsets and NK cells. Inflammatory response were determined by C-reactive protein,IL-6 and TNF-?.Morbidity,mortality and length of hospital stay were also evaluated. Results: Tolerance of enteral nutrition was excellent.Neither mortality nor serious morbidity occurred in all patients during the period of study.After the study,the levels of serum prealbumin,total lymphocytes,CD3,CD4 and CD4/CD8 ratio in the EEN group were significantly higher than the levels in the TPN group.The concentrations of IL-6 and the length of hospital stay in the EEN group were significantly lower than in the TPN group.Conclusion: Early postoperative enteral nutrition in patients with esophageal cancer is safe,and also has the benefit effects of enhancing the body status of nutrition and immune function,and reducing the inflammatory response and the length of hospital stay.

Objective:To study the effect of OSAHS on adult nasal-cycle.Method:The nasal cycle of 20 healthy adults,18 patients of snoring and 22 patients of OSAHS were examined with acoustic rhinometry,which was performed every 30 minutes in 7 hours.Result:The ratio of nasal cycle in healthy adults was(19/20,95.0%), in snoring patients was(15/18,83.0%),in patients of OSAHS was(15/22,68.2%). The mean alteration amplitude of nasal cycle in healthy adults was significantly larger than that in patients with OSAHS (P<0.05).The distribution of the healthy adults and patients with OSAHS between the typical cycle categories was significantly different(P<0.05).Conclusion:The characteristics of nasal-cycle in of OSAHS patients were different with healthy adults,which maybe owing to change of physical function of nasal cavity.

Objective To explore the clinicopathological characteristics of non-muscle-invasive bladder cancer patients association with chronic kidney disease (CKD).Methods Between Jan 2009 and Dec 2010,536 patients (390 males and 146 females with mean age of 63 years) underwent surgical treatment at our institute for pathologically proven non-muscle-invasive bladder cancer.The clinical and pathological data of these patients were reviewed,and the relationships of these factors and CKD were analyzed.Presence of CKD was confirmed in patients with estimated glomerular filtration rate (eGFR)＜ 60ml/(min · 1.73 m2)calculated using the Modification of Diet in Renal Disease Study equation.Results Of the 536 consecutive cases,57 patients (10.6％) had CKD.Compared to the patients without CKD,there were more females and older patients in the patients with CKD (52.6％ vs 24.2％ and 69 years vs 62 years,both P ＜ 0.05).The patients with CKD proned to have multiple bladder tumor (71.9％ vs 50.9％,P ＜ 0.05) and synchronous upper urinary tract urothelial carcinoma (7.0％ vs 2.3％,P ＜0.05).The history of bladder cancer and upper urinary tract urothelial carcinoma were also predominated in these patients (43.9％ vs 29.0％ and 40.4％ vs 6.5％,both P ＜ 0.05).ConclusionConcurrent CKD in non-muscle-invasive bladder cancer patients is associated with greater risk of multiple tumors in urinary tract,particularly in female patients.

The quality control and evaluation methods of Schizonepeta tenuifolia were established by HPLC fingerprint, multi index component content determination and chemical pattern recognition to provide basis for the quality control of medicinal materials. The chemical components of 25 batches of Schizonepeta tenuifolia panicle medicinal materials and decoction pieces collected were analyzed by high performance liquid chromatography, and the common pattern of fingerprint was established. A total of 22 common chromatographic peaks were calibrated, and their similarity was more than 0.9. The samples were divided into three categories according to different producing areas by cluster analysis. The results of principal component analysis and cluster analysis were consistent. Finally, five differential markers of different batches of Schizonepeta tenuifolia were selected by orthogonal partial least squares discriminant analysis. Through the identification of the reference substance, it was determined that peak 9 was hesperidin, peak 10 was rosmarinic acid, peak 13 was tilianin, peak 14 was quercetin, and peak 20 was pulegone. The quality evaluation method established in this study is stable and reliable, and is suitable for the quality control of Schizonepeta tenuifolia.
