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 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 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 evaluate the hemodynamic situation of the patients with moyamoya disease using MR perfusion imaging,and to explore the relationship between compensatory collateral circulation and perfusion. Methods:Seventy-two hospitalized patients with moyamoya disease were selected as typical moyamoya disease group,including 37 males and 35 females,aged 10 - 62 years old,all patients underwent cerebral angiography (DSA)and MR perfusion imaging.And 20 patients with out neurological history were used as control group.With mean transit time (MTT)image as a standard,the abnormal perfusion ranges were classified as region of interest (ROI),and the corresponding perfusion parameter values,including cerebral blood flow (CBF),cerebral blood volume (CBV),MTT and time to peak (TTP)were recorded,respectively.The cerebellum was used as a reference in this study,the perfusion parameters were standardized,and the relative ratios of the perfusion parameters (rMTT,rTTP,rCBF,rCBV)were obtained.Results:Compared with control group,the rMTT and rTTP of the patients in typical moyamoya disease group were prolonged and the rCBF was reduced (P <0.05 or P < 0.01), but the rCBV had no obvious difference (P >0.05).②Compared with the contralateral side,the rMTT and rTTP of the suffered side were prolonged,and the rCBF and rCBV were reduced (P < 0.05 or P < 0.01).Compared with chronic onset group,the rCBV and rCBF of the patients in acute onset group were reduced (P <0.05 or P <0.01),but the rMTT and rTTP had no statistically significant difference (P > 0.05).There were no significant differences in all parameters between hemorrhagic moyamoya disease group and ischemia group (P > 0.05 ). Conclusion:MR perfusion imaging can accurately evaluate the hemodynamic condition of moyamoya disease;MTT and TTP hve higher sensitivities than CBF and CBV.MR perfusion imaging can evaluate the compensation of collateral circulation of moyamoya disease and provide the objective basis for the clinician to select the proper surgical timing and the best operation methods.

OBJECTIVE:To investigate the occurrence of ADR induced by Shuxuening injection in Beijing area,and to pro-vide reference for rational drug use in clinic. METHODS:ADR induced by Shuxuening injection in Beijing area during 2003-2013 was classified statistically in respects of population,organs/systems involved in ADR,clinical manifestations,occurrence time, drug combination and prognosis. RESULTS:Of 1648 ADR cases,the incidence of ADR in the elderly patients was higher than young patients,and that of female patients (60.92％) was higher than that of male patients (39.14％). Multiple organs/systems were involved in Shuxuening injection-induced ADR,and top 3 were nervous system (422 cases,21.33％),skin and its appen-dants (411 cases,20.78％) and others (305 cases,15.42％). Clinical manifestations were skin rash,itching,dizziness and ner-vousness,palpitation,arrhythmia,etc. ADR mostly occurred within 5-30 min after medication. In ADR reports,there were a vari-ety of drugs combined with Shuxuening injection. Shuxuening injection combined with Alprostadil injection was most common(61 cases,accounting for 23.46％ of drug combination). Among 1648 ADR cases,there were 622 cured cases and 1039 cases im-proved,4 cases were not improved,3 cases had sequelae and 1 case died. CONCLUSIONS:Clinical application of Shuxuening in-jection should strictly follow the indications of drug package inserts;differentiation of symptoms and signs is based on specific dos-age,solvent,route of administration,etc. It is necessary to strengthen the prescription check,and strengthen the observation after medication especially for the elderly and other special groups so as to reduce and avoid ADR.
