A patient diagnosed with myoepithelial carcinoma was recently treated in our department. The neoplasm was huge, located in the left maxillofacial region, blocking both eyes, impeding feeding. About one month before admission, the tumor began to bleed frequently, about 100 ml each time, causing headache, dizziness, fatigue, and cold sweats. CT showed the maximum diameter of the tumor was about 23 cm, with uneven density, and maxillofacial bone destruction. MRI revealed internal bleeding and necrosis inside the tumor. After admission, blood routine test showed erythrocyte count 3.64 x 10(12)/L(↓), hemoglobin 106 g/L(↓), hematocrit 0.320 (↓), serum iron 6.2 μmol/L(↓). After surgery, the patient recovered smoothly.

Objective To analyze the impacts of early enteral nutrition (EN) and parenteral nutrition (PN) on the prognosis of acute pancreatitis.Method By searching relevant literature between January 1996 and August 2013 in Chinese and English databases including Wanfang,VIP,CNKI,PubMed,the Cochrane Library,CBM,and EMABSE,we compared the prognosis of acute pancreatitis after EN or PN in terms of casefatality rate,infections,multiple organ failure,and other complications.Result Compared with PN,early EN significantly reduced the case-fatality rate [OR =0.37,95％ CI (0.23,0.58),P ＜ 0.000 1],decreased the infection rate [OR =0.24,95％ CI (0.15,0.39),P ＜0.000 01],shortened hospital stay [MD =-9.87,95％ CI (-10.84,-8.89),P ＜ 0.000 01],and reduced complications [OR =0.26,95％ CI (0.12,0.58),P =0.001 0] in patients with acute pancreatitis,although the incident of multi-organ failure showed no significant difference [OR =0.35,95％ CI (0.10,1.19),P =0.09].Conclusions For patients with acute pancreatitis,early EN is superior than PN in terms of case-fatality rate,infection rate,hospital stay,and complications.Therefore,it should be applied in such patients whenever condition allows.

Objective To reconstitute hair follicles in mice using graft chambers,and to study the effect of different cell types on hair follicle regeneration.Methods Full-thickness skin was obtained from the back of C57BL/6 neonatal mice.Then,epidermal cell suspensions were prepared by shredding epidermis after trypsinization,hair follicles and dermal cells were collected by filtration,low-speed centrifugation and density gradient centrifugation,and hair follicle epithelial cells were obtained via trypsinization of hair follicles followed by filtration.Nude mice were classified into four groups to be transplanted with epidermal cells + follicular buds,dermal cells alone,epidermal cells + follicular buds + dermal cells,follicular epithelial cells + dermal cells,respectively.The cells were implanted into the dorsal skin of nude mice using fold chambers.After the grafting,the growth of skin and hairs was observed at the grafted sites on week 1,2,4 and 8,and skin specimens were obtained on week 2,4,and 8 for histological study of hair follicles using hematoxylin-eosin staining.Results After grafting,the chambers on the back of nude mice began to shed with crust formation on week 1; stunted hairs came out and follicle-like structures were seen under the microscope on week 2 at the grafted sites,normal hairs were observed on week 4 and 8 in all the mice except for those transplanted with epidermal cells + follicular buds,and the growth of hairs in mice grafted with epidermal cells + follicular buds + dermal cells and mice grafted with follicular epithelial cells +dermal cells was superior to that in mice grafted with dermal cells alone.Conclusions Hair follicles can regenerate after hair follicle cell transplantation into dorsal chambers in nude mice.Both epidermal cells and dermal cells play indispensable roles in hair follicle reconstitution.

This study aimed to promote medical and health informationization construction, strengthen the top-level design, construct a standard of medical and health information, and develop an information sharing and safety management system. For the reform of integrated hospital and clinical information systems, the Tumor Research Institute of the Second Affiliated Hospital of the Third Military Medical University aimed to solve the existing problem using pain assessment management (PAM). The PAM information platform is affiliated with the Military's No. 1 Basic Information System, which can manage PAM information. Moreover, PAM can optimize the pain assessment process and costs, and improve the work efficiency of nurses, Thus, PAM can achieve basic goals, such as data sharing, individualized records, and smart reminders, and encourages the use of pain management information systems outside the hospitals.

Objective To investigate the change of cardiac function in elderly hypertensive patients with heart valve degenerative by echocardiography.Methods A total of 126 cases were divided into a valve disease group and non-valve disease group groups.The parameters of trial size,cardiac function and pulmonary artery pressure were detected.Results Of all 126 cases were the patients with hypertension including 28.6% (36/126) of valve disease group and 71.4% (90/126) of non-valve disease.There were 31 cases with mitral valve disease,22 cases with tricuspid valve disease; 26 cases with aortic valve disease; 36 cases with double or three alvular lesions in valve disease group.There was a significant difference in ventricle size and systolic function among valve disease group and non-valve disease group and control group.But there was no significant difference in thickness of ventricular wall between valve disease group and non-valve disease group.Conclusion The elderly hypertensive patient with valve disease was an independent factor for the development of congestive heart failure.

Objective There is still a concern that epidural labor analgesia could affect uterinecontraction.The purpose of this study was to investigate the effect of epidural labor analgesia on uterinecontraction.Methods Forty ASA Ⅰ-Ⅱ primiparous women aged 20-30 yr at full term in normal uncomplicateddelivery were enrolled in this study.They were taller than 1.5 m and weighed less than 100 kg.The amnioticmembrane was artificially ruptured at 3 cm cervical dilation and a catheter was inserted into uterine cavity beyondthe head of the fetus and connected to a maternal-fetal monitor.The patients were randomly divided into 2 groupswith 20 patients in each group:Ⅰ control group received no analgesia and Ⅱ epidural group received continuousepidural analgesia(PCEA).An epidural catheter was placed at L_2-3.After a loading dose of 8-10 ml of the PCEAsolution(0.1% ropivacaine+1 ?g?ml~(-1) fentanyl)PCEA was started(bolus 3 ml,lockout interval 15 min andback ground infusion 6-8 ml?h~(-1)).The height of block was controlled below T_10.Blood samples were taken frommaternal vein at 3 cm cervical dilation(T_1),1h later(T_2)and at delivery(T_3)and from umbilical vein andamniotic fluid was aiso collected for determination of cortisol,PGE_2 and pitocin levels.VAS scores,intrauterinepressure,the frequency and duration of uterine contraction,the use of pitocin(%),incidence of cesareansection,the length of labor and neonatal Apgar scores were recorded.Results The maternal blood eortisolconcentration was significantly lower during PCEA(T_2,T_3)in group Ⅱ than in control group(P

Objective To investigate the inhibitory effects of IBI302 on experimental choroidal neovascularization (CNV).Methods Affinity of IBI302 to vascular endothelial growth factor (VEGF) family cytokines (including VEGF-A165,VEGF-A121 and placental growth factor PlGF) and complements (C3b,C4b) was determined by enzyme-linked immunosorbent assay (ELISA).The antagonist effect of IBI302 on VEGF was measured by proliferation,migration and tube formation tests of human umbilical vein endothelial cells (HUVEC).The anti-complement activity of IBI302 was measured by hemolysis test mediated by complement classical pathway and alternative pathway.Rhesus laser-induced CNV model was divided into 5 groups including model control group,bevacizumab group,IBI302 0.25 mg group,IBI302 0.50 mg group and IBI302 1.25 mg group.Fluorescein angiography and optical coherence tomography were performed on these monkeys at 14 and 28 days after drug delivery to observe the fluorescein leakage area and retinal thickness.The aqueous VEGF concentration was measured at 29 days after drug delivery.Results IBI302 showed good affinity to VEGF-A165,VEGF-A121 and PlGF,as well as C3b and C4b.IBI302 significantly inhibited the proliferation,migration and tube formation of HUVEC induced by VEGF-A165.IBI302 inhibited the hemolysis induced by complements obviously.At 14 and 28 days after drug delivery,the area of fluorescein leakage and retinal thickness in IBI302 0.25 mg group,IBI302 0.50 mg group,IBI302 1.25 mg group were reduced.The differences of the area of fluorescein leakage and retinal thickness in three IBI302 groups were not significant (P＞0.05).At 29 days after drug delivery,the VEGF concentration in the aqueous of rhesus monkey in bevacizumab group [(38.644 ± 6.521) pg/ml] was decreased than that in model control group [(94.203± 17.360) pg/ml],the difference was significant (P＜ 0.05).The VEGF concentration in the aqueous of rhesus monkey in three IBI302 groups were less than 31.300 pg/ml.Conclusion IBI302 inhibited experimental CNV through blocking the activity of VEGF and complement.
