10 cm respectively from the tumor),the metastatic rate of lymph nodes was 34.7%,2.5% and 1.7%,respectively.The metastatic rate of LN in right colon was significantly higher than that in left colon(52.0% vs 33.8%,P

Objective To discuss the safety management of hemodialysis equipment for safe and effective treatment to patients.Methods The management methods were summarized in aspects of the installation,utilization and maintenance of hemodialysis equipment.Results The hemodialysis patients received the safe and effective treatment through the strict management and the standardized system.Conclusion The standardized management can not only reduce the unnecessary failures of the equipment,and prolong the service life,but also increase the utilization rate of the equipment,and provide the best,safest and most satisfactory treatment for patients.

Objective To investigate effects of cerebral isehemic preconditioning on neurological function,in- farct volume,and the expression of caspase-3 in brain issue after brain ischemia again,and to investigate the brain protection mechanism produced by cerebral ischemia preconditioning.Methods 48 healthy male Sprague-Dawley (SD)rats(weighted 200～250g)were randomly divided into 2 groups:ischemia group(n=24),ischemia precondi- tioning group(namely preconditioning group,n=24).Each group was divided into 4 subgroups according to 6h,1d, 2d,4d after ischemia again.Results At the same point of time after ischemia,neurological deficit in preconditioning group was much less than that in ischemia group,the difference was significant(P

Objective To measure and analyze the staffing standards of family doctor interdisciplinary team by means of the WHO workload indicator of staffing need (WISN)method,for reference of the government in building family doctor interdisciplinary teams.Methods 150 community health centers in 16 provinces were selected.The related data from 150 centers were collected to analyze the population served by each family doctor,and the staffing standards of family doctor interdisciplinary team by means of the WHO workload indicator of staffing need(WISN)method.Results There were 10 721 community health professionals in the sample centers which provide 132.14 million standard equivalents of service to the public.1 9 6 1 6 community health professionals were needed to ensure the quality of service and no extra workload after work for professionals.Averagely,each family doctor can serve 1 558 residents,who needs 1.3~1.5 nurses or public health workers.Conclusions A huge gap was found for community health professionals.The population served by each family doctor should be lowered compared to the governmental requirement and more nurses should be introduced to the family doctor interdisciplinary team.

Objective:To investigate effects of depside salt from salvia miltiorrhiza(DSSM)on the dental pulp of rats under repeated exposure to +Gz acceleration.Methods:27 male SD rats were randomly divided into 9 groups(n =3).The rats in negative control group was only fixed with rats kept-keeling device,in positive control group were exposed to +5 Gz and +10 Gz respectively for 30 s each time,5 times per day,4 days per week,for 3 consecutive weeks.The rats in other groups were respectively given DSSMat 2,6 and 18 mg/kg respectively 30 min before each +Gz exposure.The rats in negative and positive control groups were injected with 0.9%sodium chloride solution 30 min prior to +Gz exposure.After the experiment,The pulp changes were observed by HE staining.Real time qPCR was applied to determine the relative expression of heat sheck protein(HSP70)mRNA.Results:+Gz exposure decreased the activity degree of the rats,and resulted in damage of rat dental pulp.With the increase of +Gz value,the relative expression of HSP70 mRNA was increased(P ＜0.05).HSP70 mRNA expression in drug groups was less than that in their own positive control groups,but showed statistical significance only in the 18 mg/kg and +10 Gz group(P ＜0.05).Conclusion:+Gz exposure may dam-age dental pulp.DSSMhas certain protective effect under +Gz exposure.

Objective To observe the relationship between homocysteine (Hcy),C-reactive protein (CRP) and type 2 diabetes peripheral vascular disease (PVD).Methods Fifty-eight patients with type 2 diabetes according to the condition of PVD were divided into simple type 2 diabetes mellitus group (DM group,30 cases) and PVD group (28 cases).Twenty-five healthy people were chosen at the same period as control group.The fasting blood glucose (FBG),glycosylated hemoglobin (HbA1c),total cholesterol(TC),triglyceride (TG),high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C),Hcy and CRP levels were detected among 3 groups,and the body mass index (BMI),ankle brachial index(ABI) was calculated.Results The BMI,TG,TC and HDL-C levels among 3 groups had no statistical significance (P ＞0.05).The FBG,HbA1c and LDL-C in DM group and PVD group were significantly higher than those in control group [(7.54 ± 1.25),(8.12 ± 1.57) mmol/L vs.(4.68 ±0.54)mmol/L; (6.92 ± 0.89)％,(7.54 ± 0.97)％ vs.(4.80 ± 0.54)％ ; (3.79 ± 0.73),(4.41 ± 0.93) mmol/L vs.(2.68 ± 0.54) mmol/L],and the difference was statistically significant (P ＜ 0.05).But the difference between PVD group and DM group had no statistical significance (P ＞ 0.05).Hcy and CRP in DM group and PVD group were higher than those in control group [(10.26 ± 3.62),(19.83 ± 5.54) μ mol/L vs.(8.92 ± 2.41)μ mol/L; (4.12 ±0.57),(5.47 ±0.85) mg/L vs.(2.73 ±0.54) mg/L],ABI was lower than that in control group(0.92 ± 0.18,0.81 ± 0.16 vs.1.02 ± 0.23),and the difference was statistically significant (P ＜ 0.05);Hcy,CRP in PVD group were obviously higher than those in DM group,ABI was lower than that in DM group,and the differences were statistically significant (P＜ 0.05).Spearman analysis showed that Hcy was negatively correlated with ABI (r =-0.635,P ＜ 0.05),CRP was negatively correlated with ABI (r =-0.529,P ＜ 0.05),and Hcy was positively correlated with CRP (r =0.528,P ＜ 0.05).The partial correlation analysis results showed that Hcy and ABI still showed a negative correlation (r =-0.315,P ＜ 0.05),CRP and ABI still showed a negative correlation (r =-0.243,P ＜ 0.05).Conclusion Hcy and CRP participating in the occurrence and development of type 2 diabetes PVD,can be used as a predictor of type 2 diabetes PVD.

Objectives To analysis the expression difference of eIF4E in bone marrow between the acute myeloid leukemia (AML) and the non-tumor patient,before and after induction therapy,and the different subtypes of AML,and to explore the relation between eIF4E and other molecular biology abnormalities in AML.Methods The bone marrow specimens of newly diagnosed AML and non-tumor control patients were collected.The expression level of eIF4E was detected by RT-PCR.Results The positive rate of eIF4E was 65.2 ％ (101/155) in AML.eIF4E turned to negative in 12 patients (17.6 ％) who got complete remission after induction therapy.eIF4E was negatively expressed in bone marrow of the nontumor control patients.The positive rates of eIF4E were 75.0 ％ (15/20) and 80.8 ％ (21/26) in M4 and M5 type AML,respectively,and was 59.6 ％ (65/109) in other subtype AML (P ＞ 0.05).FLT3/ITD gene mutation was found in 26 cases of newly diagnosed AML.The eIF4E expression and FLT3-ITD gene mutation were independent each other (P ＞ 0.05).Conclusions eIF4E is positive in most of the newly diagnosed AML and turns to negative in part of AML achieving complete remission.The expression of eIF4E is no difference among different subtype of AMLs.eIF4E and FLT3-ITD gene mutation are independent each other.

AIM:To observe the treatment for ptosis patients with severe undercorrection after frontal muscle flap suspension surgery. · METHODS: Totally 46 patients ( 67 eyes ) were randomly divided into 2 groups: 23 cases ( 33 eyes ) in Group A were given conjoint fascial sheath ( CFS ) suspension surgery; 23 cases ( 34 eyes ) in Group B Whitnall ligament suspension. Postoperative follow-up was 6mo. Corrected rate, recurrence rate and postoperative adverse reactions were compared and analyzed. ·RESULTS:The corrected rates of the two groups were both satisfied without significant difference between the two groups (P>0. 05). the Whitnall ligament suspension surgery had less recurrence than CFS suspension surgery, but the difference was not statistically significant (P>0. 05). The rate of hypophasis after CFS suspension surgery was significantly less than that after Whitnall ligament suspension (P<0. 05). ·CONCLUSION:The two operations both have satisfied corrected rate and low recurrence rate, the Whitnall ligament suspension surgery is less damaging and more easy to operate, while CFS suspension surgery is repeatable and less rate of hypophasis.
