AlM: To explore the clinical significances and changes of related parameters of corneal endothelial cell in keratouveitis patients before and after treatment.
METHODS:Fifty-two keratouveitis patients ( 52 eyes ) diagnosed and treated in our hospital from October 2012 to December 2013 were collected. Before and after treatment, the related parameters of corneal endothelial cell in all patients were measured with non - contact corneal specular microscope and these parameters were statistically analyzed.
RESULTS: Compared with the normal group, obvious endothelial cell edema and great variation was observed in diseased group. The shorter duration of treatment, the better the recovery of endothelial cells and the fewer cells lose. Conversely, the longer the healing of normal hexagonal cell ratio was smaller, the larger the coefficient of variation. Before and after treatment, the differences of each parameter were statistical significance (P<0. 05).
CONCLUSlON: The functional recovery of corneal endothelial cell has directly relation with disease times.

Objective To study the relationships of hemoglobin(Hb)level with the levels of neurohormones,and cytokines,and the effect of them on ventricular remodeling in patients with congestive heart failure(CHF). Methods Hb level,serum angiotensinⅡ(Ang Ⅱ ),tumor necrosis factor-α(TNF-α),nitric oxide(NO),soluble intereellular adhesion molecule-1(sICAM-1)and B-type natriuretic peptide(BNP)were measured in 121 CHF patients.The left ventrieular ejection fraction (LVEF)from echocardiography,left ventricular mass index(LVMI),and mean wall stress(MWS)were calculated. Results The levels of Ang Ⅱ,TNF-α,NO,siCAM-1,BNP[(144.5±64.1)ng/L,(92.3±6.4)ng/L,(65.2±4.2)μmol/L,(253.6±26.0)μg/L,(1294.0±223.0)ng/L]and LVMI,MWS in the anemia group of CHF patients were higher than those in the non-anemia group[(76.7±48.5)ng/L,(55.6±10.2)ng/L,(42.1±11.9)μmol/L,(237.18±33.26)μg/L,(437.0±115.0)ng/L,all P＜0.01].With the increase of anemia severity,the levels of AngⅡ,TNF-α,NO,siCAM-1,BNP and LVMI,MWS were significantly increased.There were negative correlations between Hb level and the 1evels of AngⅡ,TNF-α,NO,siCAM-1,BNP,LVMI,MWS(r=-0.8173,-0.8509,-0.6001,-0.6692,-0.6283,-0.8604,-0.8733,all P＜0.01),and negative correlations between LVMI,MWS and Hb levels and LVEF(P＜0.01). Conclusions Neurohormones and cytokines play roles in ventrieular remodeling and anemia in CHF aggravates the severity of ventricular remodeling.

Exosome is a self-secreted phospholipid bilayer nanovesicles, and has shown great potential in drug delivery field due to the important advantages of low immunogenicity and homologous targeting. Phototherapy, mainly includes photodynamic therapy (PDT) and photothermal therapy (PTT), utilize light to activate photoactive drug for tumor cell killing. The advanced therapeutic strategy shows low toxic side-effect and non-invasion precise advantages, and thus has made great progress in tumor treatment over the past few years. Therefore, using exosomes as a drug delivery system to deliver phototherapeutic agents can improve therapeutic performances with a reduced side-effect, and further enhance their application potential for clinical tumor therapy. This review focus on the rising cross-subjects field involving exosomes and phototherapy, and mainly introduce the research progress and relative case of exosomes-based delivery system for cancer phototherapy. Additionally, the advantages and challenges of exosome-based phototherapy are also discussed and proposed.

Objective To evaluate endoscopic ultrasonography (EUS) for TN restaging and predicting response to advanced gastric cancer after neoadjuvant chemotherapy. Methods A total of 22 patients,15 males and 7 females, mean age 64 (36-80 years ), with advanced gastric cancer were recruited to the study from June 2007 to December 2009 with written informed consents. All patients underwent 3 cycles of neoadjuvant chemotherapy ( Folfox 6 ), and subsequent surgery ( R0 resction) in 3-4 weeks after chemotherapy. EUS was performed 1-2 weeks before and 1-2 weeks after chemotherapy. EUS TN staging was compared with pathological findings. The correlation of peri-chemotherapy EUS TN staging with postoperative pathological response was evaluated. Results After chemotherapy, the overall accuracy of EUS T staging was 63.6% (14/22), with overstaging (36. 4%, 8/22) more frequent than understaging (0). The overall accuracy of N staging was 54. 5% (12/22) with 4 ( 18. 2%, 4/22) overstaging and 6 ( 27. 3%, 6/22 ) understaging. EUS revealed T and/or N downstaging ( concyrrence of T and N downstaging was accounted once) after chemotherapy in 10 patients, with 9 T downstaging (4 from T3 to T2, 5 from T4 to T3) and 4 N downstaging (4 from N1 to N0). TN downstaging was correlated with pathological response, with 7 patients achieving pathological response 2 and 1 patient 3. Conclusion T and N restaging by EUS after neoadjuvant chemotherapy in patients with locally advanced gastric cancer is not accurate enough. However, T and/or N downstaging confirmed by EUS is well correlated with a better degree of pathological response to chemotherapy.

Objective To investigate the expression and clinical significance of Survivin and Ki-67 in breast carcinoma,and explore their correlation.Method The expression of Survivin and Ki-67 in breast carcinoma(49 cases)and normal breast tissues(12 cases)were examined by immunohistochemical method.Results The positive expression rates of Survivin and Ki-67 in breast carcinoma were significantly higher than those in normal breast tissues(P<0.05).The expression of Survivin was significantly related to clinical stage and lymph node metastasis(P<0.05).The expression of Ki-67 Was significantly related to clinical stage,lymph node metastasis,and pathological grade(P<0.05).The expression of Survivin was obviously related with Ki-67 in breast carcinoma(r=0.734,P<0.05).Conclusions The overexpression of Survivin and Ki-67 may play a cooperative role in the occurrence and development of breast carcinoma.They may serve as useful markers for assessment of biological behavior of breast carcinoma.

Objective To collect the data of present basic constructive situation of intensive care units (ICUs) in second and tertiary grade hospitals in Xinjiang Uygur Autonomous Region and to provide a data base beneficial to the construction of ICUs in the whole region.Methods The information including basic situation of ICUs in a total of 49 second and tertiary grade hospitals as samples in Xinjiang Uygur Autonomous Region were investigated by questionnaire survey from December 2012 to April 2013. The contents of questionnaire chiefly included the basic situations of hospitals, ICU constructions, ICU human resources and allocation of equipments.Results Forty-nine questionnaires were sent out, and all of them gave answers, the recovery rate being 100%. In the whole region of Xinjiang, there were 49 second and tertiary grade hospitals with establishment of 66 various types of ICUs. ① Medical unit basic situation: the second grade A hospitals accounted for 59.2%, and the tertiary grade A hospitals, 34.7%. There was a larger proportion of local hospitals (67.3%); most of the hospitals had beds over 500 (57.14%), the designed hospital bed number was 41 403, and 35 442 beds were open up for service (85.60%). ② The ICU basic construction situation: the construction of ICUs concentrated mainly after the year 2000, from 2000 to 2010, a total of 37 units, and from 2010 to 2012, 12 units were constructed; when they opened to the public, the beds were relatively few, and the ICUs containing less than 10 beds occupied 79.00%. In the 66 ICUs surveyed, there were 43 general ICUs, accounting the largest proportion, followed by 7 emergency ICUs, and the least were 1 neurosurgery and 1 cardiac surgery ICU. In the 66 ICUs, all together 765 beds were prepared, but actually 808 beds were opening up to public; most of ICUs had 5 - 20 beds, accounting for 71% in all the ICUs. At present, in the whole Xinjiang region, the rate of beds in ICUs in various grades of hospitals opening to the outside for use accounted for more than 80% of which 56% ICUs were almost turning round fully. ③ ICU human resources situation: totally, there were 484 doctors in ICUs in the whole region, the ratio of full-time doctor to nurses was 1:3.50, the ratio for bed to physician 1:0.55 and the ratio for bed to nurse 1:0.92. The title of doctor was primarily resident, and the various title gradient levels were good. Most doctors graduated from a regular medical college, and the doctors having obtained a master degree were few. The physician professional backgrounds were mainly critical disease medicine, emergency medicine and respiratory medicine, the professional relevance being good; the chief way of ICU physicians to engage in advanced study of their professional training was in China, and generally they joined professional continuing education programs poorly, mostly joining once a year or non at all. The physicians who obtained the identification of Chinese critical care medicine specialist accounted only for 23.56%. ④ ICU equipment allocation situation: according to the requirements of ICU construction guidelines, the equipments must be allocated including bedside monitors (703 units), ventilators (516 units) and infusion pumps (702 units), occupying the highest proportion. In the optional equipments, there were enteral nutritional pump (89 stations), blood glucose monitoring device (57 units) and anti-decubitus mattresses (54 units), the proportion being the largest, bispectral index monitor (2 units), extracorporeal membrane oxygenation (ECMO, 1 table) and gastric mucosal carbon dioxide tension pHi meter (0 unit), the proportion being the least or non at all.Conclusions In the whole Xinjiang region, the construction of ICUs is still at the developing stage, and needs to further strengthen the standardized construction. The human resources, equipments, etc. are not distributed in balance, and it is necessary to move forward the adjustment to benefit the development of ICUs in the whole region.
