The currently unfavorable physician - patient relationship has lead to a total loss of interests from multiple sides of hospitals,patients,medical staff,medical education and the society,which specifies in the wellbeing loss of patients and the whole population.The social stability has also been affected.The health care reform should aim to minimize the conflicts between doctors and patients,thus the above mentioned losses will be diminished and a harmonious physician - patient relationship will be built up and the win - win pattern of benefits between doctors and patients will also be realized.Multiple efforts from the government,society,hospitals,medical staff,and patients are all needed to achieve such a goal.

?AIM:To study the changes of ocular surface in cataract patients with Meibomian gland dysfunction ( MGD) who treated with Meibomian gland massage before surgery.?METHODS: Totally 90 patients ( 93 eyes ) with cataract and MGD were randomly divided into two groups. Patients in experimental group were treated with hot compress and Meibomian gland massage every day before surgery, while the patients in the control group were not taken. Two groups of patients received phacoemulsification combined with intraocular lens implantation. Lid margin abnormalities, secretion characteristics, Schimer I test ( SⅠt) and tear film break-up time ( BUT ) were recorded and compared between two groups using slit lamp microscope inspection preoperatively and postoperatively 1wk.?RESULTS:In the control group, the postoperative score of eyelid margin and Meibomian gland secretion was increased significantly than preoperative, while the value of BUT and SⅠt was down significantly. Compared with control group, the postoperative score of eyelid margin shape and Meibomian gland secretion in the experimental group was decreased significantly, while the value of BUT and SIT improved significantly (P<0. 05).?CONCLUSION: Phacoemulsification can aggravate the Meibomian gland dysfunction and have some extent of effects on the ocular surface. Meibomian gland massage before surgery can significantly improve the function of Meibomian gland and the state of ocular surface in patients with MDG.

The gene types of breast cancer can be classified into three types according to its molecules: Luminal type A, Luminal type B, HER-2-positive type, triple negative type. Authors combined pathological characteristics of breast cancer, biological characteristics, and comprehensive treatment, used syndrome typing based medication, and explored treatment meticulous ideas and methods of "treating the same disease with different methods" as well as "different treatment methods in accordance with patients individually".

Objective To explore the effect of postasphyxial-serum in neonate on the expressions of Bcl-2-antagonist of cell death(BAD)and Bcl-2-associated X protein(BAX)in renal tubular cells(HK-2).Methods HK-2 cells were used as target cells.The experiment were divided into control group,asphyxia group and pyrrolodine dithiocarbamate(PDTC)blocking group.Control group:DMEM culture fluid was not contained asphyxia blood serum in every group;asphxia group:DMEM culture fluid contained 20 mL/L asphyxia blood serum in every group;PDTC blocking group:DMEM culture fluid contained 20 mL/L asphyxia blood serum and 40 ?mol/L PDTC in every group.The expressions of both BAD and BAX on cytoplast were detected by immunohistochemical method.Results Calculated Points according to HSCORE,compared with controls group[(1.97?0.26)and(1.77?0.11)],after stimulated with postasphyxial-serum,the expressions of both BAD and BAX of HK-2 cells of asphyxia group[(2.73?0.20)and(2.44?0.13)] and PDTC blocking group[(2.38?0.13)and(2.17?0.08)] significantly increased[F(BAD)=28.61,F(BAX)=15.51 Pa

ObjectiveTo explore the detection significance of insulin-like growth factor-I(IGF-I),IGF-binding protein-3(IGFBP-3) in children with acute lymphoblastic leukemia(ALL).MethodsSerum samples were obtained from 30 ALL children without any medication;serum control samples were obtained from 30 cases of healthy children.There were no significant differences of body weight,age and sex between 2 groups.All children had no case history of liver,kidney,malnutrition and endocrine system disease.IGF-Ⅰ was determined by radioimmunoassay kit.IGFBP-3 was determined by immunoradiometric kit.The data were analyzed with SPSS 11.0 software.ResultsThe level of IGF-Ⅰ in ALL group [(18.95?4.02)?106 g/L] was significantly lower than that in control group [(34.12?7.86)?106 g/L](t =9.412P

AIM:To compare the higher-order aberrations between implantations of AcrySof and AcrySof ReStor multifocal aspherical intraocular lens(IOL) with various pupil diameters.METHODS:Fifty-four patients(62 eyes)with bilateral senile cataracts were retrospectively selected.Patients were operated with phacoemulsification and IOL implantation.They were divided into two groups based on the IOL implantation of AcrySof IQ and AcrySof ReStor.Wave front aberration:spherical aberration(C12)and the root mean square of the total higher-order aberration(RMSh)were observed 3 months after surgery.RESULTS:The larger the pupil was, the higher the C12 and RMSh were in the eyes (P<0.01).There were no statistical differences in C12 or RMSh between two groups at 5, 6 or 7mm pupil diameters (P>0.05). CONCLUSION:There are no differences between AcrySof IQ group and AcrySof ReStor group at 5, 6 or 7mm pupil diameters.

OBJECTIVETo observe the influence of lead exposure on the activity of nitric oxide synthase (NOS) in different brain regions of rat.

METHODSBy establishing a series of rat models exposed to different low levels of lead (drinking water containing 0.025%, 0.050%, 0.075% of lead acetate) during developing period, NOS activities in hippocampus, cerebellum, cerebral cortex and brain stem were studied.

RESULTSOn the 21st day after birth, NOS activities in hippocampus of three levels of lead exposed groups [(1.53 +/- 0.20), (1.66 +/- 0.23), (1.88 +/- 0.32) U/mg pro respectively], and in cerebellum [(0.87 +/- 0.24), (0.85 +/- 0.09), (0.91 +/- 0.18) U/mg pro respectively] were significantly lower than those of control group [(2.36 +/- 0.18), (1.41 +/- 0.18) U/mg pro, respectively, P < 0.01]. NOS activities in cerebral cortex of 0.075% group [at 7, 14, 21 d of age [(1.29 +/- 0.14), (1.03 +/- 0.15), (0.69 +/- 0.10) U/mg pro] were significantly lower than those in control group [(2.54 +/- 0.31), (1.64 +/- 0.22), (1.24 +/- 0.14) U/mg pro respectively], and 0.025% group [(2.42 +/- 0.19), (1.59 +/- 0.17), (1.27 +/- 0.12) U/mg pro respectively], and 0.050% group [(2.56 +/- 0.53), (1.77 +/- 0.19), (1.24 +/- 0.10) U/mg pro respectively, P < 0.05]. There were no significant differences among control, 0.025%, and 0.050% groups (P > 0.05). Lead exposure had no influence on NOS activity in brain stem at the same age (P > 0.05).

CONCLUSIONNOS activities in hippocampus, cerebellum and cerebral cortex were inhibited by low level lead exposure and the degree of the effect was related to Pb exposure time and/or level of Pb exposed.
