Objective To observe blood pressure variability(BPV) and analyze the correlation between BPV and carotid artery-intima media thickness (CA-IMT) in elderly hypertension. Methods Totally 156 patients with primary hypertension were divided into 3 groups:patients aged 45-59years (48 cases) 60-79 years (52 eases),and 80-94 years (56 cases).24 h ambulatory blood pressure monitoring (24 h ABPM) was used to measure 24 h mean systolic blood pressure (24 hSBP),24 h SBP standard deviation (24 h SBPSD),and to calculate 24 h SBP coefficient of variation (24 hSBP CV).Meanwhile,SBP of daytime (DSBP) and nighttime (NSBP),DSBPSD and NSBPSD were measured,and DSBPCV and NSBPCV were calculated.CA-IMT was examined by ultrasound.Spearman rank correlation coefficient was employed to assess the relationship between above indicators and CA-IMT,age. Results No differences were found in 24 h SBP,DSBP and NSBP among the groups.24 hSBPSD( 14.3 ± 3.1),24 h SBPCV ( 11.5 ± 2.1 ),DSBPSD ( 13.8 ± 3.8),DSBPCV ( 10.7 ± 2.6),NSBPSD (13.4±3.3)of patients aged 80-90 years were higher than those of patients aged 60-79 years (12.2±2.5,10.1±2.0,11.6±2.6,9.5±2.3,11.9±2.8)and patients aged 40-59 years (11.7±2.8,9.4±1.9,10.9±3.1,8.4±1.8,11.6±3.0) (P＜0.05).NSBPCVof patients aged 80-90years was increased as compared with patients aged 40-59 years (10.9±2.7 vs.9.6±2.4,P＜0.05).24 h SBPSD,24 h SBPCV were associated with CA-IMT and age(r=0.26,0.39;0.28,0.42,all P＜0.01). Conclusions SBPSD and SBPCV of 24 h ABPM are higher in very older patient with hypertension and could be the useful markers for assessment of BPV.

Objective To investigate the effects of peri-operative enteral nutrition (EN) and antibiotics on intestinal flora balance in patients with esophageal carcinoma.Methods Sixty patients were randomly divided into six groups:Group B,treated with antibiotics for 3 days and supported with EN before and after operation; Group C,treated with antibiotics for 3 days and supported with parenteral nutrition (PN) before operation and EN after operation ; Group D,treated with antibiotics for 3 days and supported with PN before and after operation ; Group E,treated with antibiotics for 7 days and supported with EN before and after operation; Group F,treated with antibiotics for 7 days and supported with PN before operation and EN after operation ; and Group G,treated with antibiotics for 7 days and supported with PN before and after operation.The first stool after surgery was obtained and tested for Bacteroides,Bifidobacterium,Lactobacillus,Escherichia coli,and Enterococcus.Ten healthy adults were enrolled as the blank control group.The numbers of the flora and ratio of Bifidobacteria to Enterococci (B/E) were compared.Complications such as incision infections,lung infections,and anastomotic fistula were recorded.Results The numbers of Bifidobacterium [(10.59 ± 0.39) vs.(10.88 ± 0.10) lg10n/ml,P =0.186),Lactobacillus [(8.59±0.31) vs.(8.72 ±0.22) lg10n/ml,P=0.534],Escherichia coli [(8.43 ±0.50) vs.(8.67 ±0.24) lg10n/ml,P=0.266],Enterococcus [(7.40 ±0.61) vs.(7.78 ±0.16) lg10n/ml,P =0.111],and B/E value [(1.2589 ± 0.0644) vs.(1.2560 ± 0.0330),P =0.825] in the Group B were not significantly different from the blank control group.The numbers of Bacteroids [(11.08 ± 0.48),P =0.139 ; (9.23 ± 0.42),P =0.000; (10.80±0.26),P=0.004; (10.24±0.45),P=0.000; (8.05±0.53),P=0.000vs.(11.36±0.48) lg10n/ml],Bifidobacterium [(10.19 ±0.49),P=0.062; (9.00 ±0.52),P=0.000; (9.31 ±0.45),P=0.000; (8.47±0.56),P=0.000; (6.99 ±0.56),P =0.000 vs.(10.59±0.39) lg10n/ml],Lactobacillus [(7.99 ± 0.58),P =0.006 ; (6.84 ± 0.47),P =0.000 ; (7.72 ± 0.35),P =0.000 ; (6.93 ±0.43),P =0.000; (5.93 ±0.76),P=0.000 vs.(8.59 ±0.31) lg10n/ml],Escherichia coli [(8.19 ±0.43),P=0.258; (7.93±0.60),P=0.020; (7.47±0.43),P=0.000; (6.90±0.42),P=0.000; (6.58±0.57),P =0.000 vs.(8.43 ± 0.50) lg10n/ml],and Enterococcus [(6.90 ± 0.54),P =0.037 ; (5.89 ± 0.68),P =0.000; (6.20±0.52),P=0.000; (5.91 ±0.39),P=0.000; (5.14±0.58),P=0.000 vs.(7.40±0.61) lg10n/ml] of groups C,D,E,F,and G decreased compared with those of the Group B.The values of B/Ein the D and G groups decreased significantly when compared to the blank control group (1.1433 ±0.1350,P =0.025 ; 1.0706 ± 0.1413,P =0.000 vs.1.2560 ± 0.0330).The incidences of pulmonary infections (x2 =3.647,P =0.601) and anastomotic leak (x2 =5.000,P =0.416) among all groups were not significantly different.Conclusions EN applied 3 days before surgery and after surgery is beneficial for maintaining the balance of intestinal flora.Long-term administration of antibiotics may cause dysbacteriosis and even increase complications.

Objective To investigate the application of functional assessment to determine the needs of intermediate care services of elderly,and to analyze the needs of intermediate care services of elderly patients in different grades of hospital,different departments and different age.Method 2481 cases of patients aged over 60 years hospitalized due to acute diseases were collected.The ability of activities of daily living (ADL) scale (Barthel index) and limb function were determined in patients aged over 60 years within 1 week after admission as acute diseases.According to the clinical data and scoring scales,the patients were divided into three groups of self-care group without declined independent function of life with Barthel index ＞ 95 points;intermediate care group in whom the ability of daily activities was decreased due to the acute diseases,the function of the body was decreased,and Barthel index was between 45 ～ 95 points;and long-term care group with long term bed rest,severely declined autonomic function or complete dependence and Barthel index less than 45 points,and no opportunity of further recovery.A total of 382 elderly patients (195 male) were in intermediate care group.Analyzed were the intermediate care needs of elderly patients in different levels of hospitals,different departments (including respiratory,cardiovascular,emergency department,geriatrics) and different age.Results The proportion of needs of intermediate care services was 16.1％ (194/1205) in third grade hospitals,24.3％ (33/136) in grade 2 hospitals,38.1 ％ (91/239) in grade 1 hospitals,and 7.1％ (64/901) in community hospital.In general hospital the proportion of needs of intermediate care services were 24.5 ％ (13/53) in emergency department,12.1％ (4/33) in cardiology department,14.6％ (6/41) in respiratory department,and 10.4％ (7/ 67) in geriatric department.The proportion of needs of intermediate care services was 19.0％ (22/ 116) in age group of 60～69,42.2％ (62/147) in age groupof 70～79,and 28.6％ (34/119) in age group of over 80 years.Conclusion The needs of intermediate care services are different in different age groups.Patients aged 70 ～ 79 years have the highest needs of intermediate care services.The needs of intermediate care services are different in different grade levels of hospitals and in different departments.

Examination reform was explored in Introduction to clinical medicine, and a new evaluation system was constructed which included the combination of formative assessment and sum-mative assessment as well as content system, operation system and monitoring system. The feedback mechanism of formative assessment was put into a full use to improve the teaching effect in this new evaluation system. At the same time, the method of summative assessment was substituted from the traditional closed-book exam to literature translation and presentation carried out by groups. The com-bination of summative assessment and formative assessment could evaluate the teaching efficiency of introduction to clinical medicine more comprehensively and objectively. In addition, it played an ac-tive role in improving students' comprehensive ability and their learning enthusiasm.
