The role of general practitioners in the UK was analyzed and we found that in the UK, there was normalized general medical education system, perfect general practitioner training sys-tem, specific responsibilities and assessment index, close liaison group between primary and secondary care, strong economic supporting measures and high degree of recognition. Therefore, to deepen med-ical reform and improve basic medical service, we must accelerate general practitioners training, im-prove practice ability of general practitioners, establish the first-treatment system in community, reit-erate role of gatekeeper, enhance the payment of general practitioner and increase their sense of iden-tity. At the same time, we must strengthen the informatization construction, set up the first-treatment in the community and the patency of two-way referral system.

Objective To evaluate the mental status of malignant hematologic patients, explore the morbidity of depression in malignant hematologic patients, and investigate valid interventional treatment on them. Methods 134 malignant hematologic patients were evaluated by SDS and HAMD, and 49 patientswere selected who was diagnosed depressive disorder then randomly divided into 2 groups. One was experimental group and the other control group. The patients of experimental group were treated with antidepressant drug and mental intervention during common therapy, while the patients of control group only took common therapy. The change of immunological function after treatment was detected. Results The morbidity of depression in malignant hematologic patients was 37 %. The scores of SDS and HAMD were significandy decreased and the depressive symptoms were notablely improved in experimental group and there were significant differences after treatment and before treatment (P <0.01), but there was no significant difference in control group (P >0.1). The NPY plasma levels significantly increased after treatment in experimental group(P <0.01), but there was no significant difference in control group(P >0.05); the CD+4/CD+4 values of patients in the experimental group were significantly increased after treatments. Statistical analysis revealed significant differences in the experimental group patients between pre-treat and after-treat (P <0,05),but no obvious difference in the patients of control group (P>0.5). Conclusion Mental intervention and antidepressive treatment can improve all of the depression, immunological function and quality of life of malignant hematologic patients.

Background Diabetic complication is associated with lipid peroxidation.Aldehyde dehydrogenases (ALDH) catalyze the irreversible oxidation of a variety of biological aldehydes,including lipid-derived aldehydes (LDAs),and thus protect organs and tissues from toxic LDAs.Understanding the activity of ALDH in different ocular tissues in diabetic subjects is very important for prevention and treatment of diabetic ocular complications.Objective This research aimed to investigate the activity and expression of ALDH in different ocular tissues in diabetic rats and to explore the mechanism of ALDH in diabetes-induced eye disease.Methods Twenty-eight healthy SPF male Sprague-Dawley(SD) rats weighted 170-180 g were randomly divided into the normal control group and diabetic group.The diabetic animal model was established by intraperitonial injection of 4％ streptozotocin at 65 mg/kg.Isometric citric acid buffer was injected in the rats of the normal control group.The rats were sacrificed in each group 2 and 4 months after the establishment of the diabetic models,and eyeballs were obtained for the preparation of corneal,lens and retinal homogenates.ALDH activity was detected using a multifunctional microplate reader SpectraMax M5,and ALDH content was measured by ELISA at the wavelength of 450 nm with the SpectraMax M5 ELISA reader.Results The blood glucose level in diabetic rats was significantly elevated at various time points compared with the normal control group(P=0.000),and body weights were evidently lower in the diabetic group than in the normal group (P =0.000).The activities of ALDH (A340) in corneal,lens and retinal tissues in the diabetic group were increased in comparison with the normal control group (F =396.601,P=0.000),and showed an enhancement with the lapsing of time (F =53.139,P =0.000).In addition,the highest level of ALDH was found in the cornea and the lowest level in the lens(F =6973.000,P=0.000).The expression level of ALDH in the corneal,lens and retinal homogenates was significantly higher in the diabetic group compared with the normal control group (F=312.985,P =0.000) and showed a considerable increase over the course (F =19.203,P=0.000).The highest expression level was seen in the cornea and the lowest was in the lens,with a significant difference among these three kinds of tissues (F =3243.000,P =0.000).Conclusions ALDH can protect ocular tissue from the damage of lipid peroxidation.Thess results suggest that ALDH plays a role in preventing diabetes-related ocular complications.

Objective To establish a simple and sensitive method for the determination of serum copper by spectrophotometry.Methods Nitro-PAPS was used as a coloring agent for serum copper in the presence of surfactants Tween-80 and Triton X-100 and the formed complex was measured by spectrophotometry.Results The maximum absorption wavelength of the complex was 570 nm and the molar absorption coefficient was 7.95?10~4 L/(mol?cm).The lineafity of the method was up to 63.0 ?mol/L and the recoveries ranged from 98.6% to 103.1%.The within-run and between-run CVs were 2.1%-3.3% and 2.7%-3.8%.The method(Y)was compared with an AAS method(X)and a correlation of Y=1.01X -0.27(r=0.998 2)was obtained.A reference interval(x~-?2s)determined with this method on 68 individuals was 9.7-24.1 ?moL/L.Conclusions A simple and sensitive method for serum copper has been established.It may used for the analysis of serum copper in clinical laboratories.

In industrial glutamate fermentation, intermitted feeding glucose with the help of off-line glucose measurement is generally necessary. This kind of feeding strategy could cause large variations in glucose concentration so that it is not favorable for the achievement of efficient and stable glutamate fermentation. Glutamate fermentation is characterized with typical non-growth association behavior, and during glutamate production phase glucose consumption is closely correlated with ammonia consumption. In this study, glucose concentration was controlled at various pre-determined levels by predicting glucose consumption amount and thus its concentration with the aid of on-line monitoring ammonia consumption. When glucose concentration was controlled around a lower level of 5 g/L~10 g/L, the final glutamate concentration could reach a relatively higher level of 80 g/L. In this way, the huge osmotic stress change due to the large glucose concentration variation with the intermitted feeding method could be avoided and the glutamate fermentation performance enhancement be expected.

OBJECTIVETo analyze the long-term results of TIPS, TIPS with coronary vein occlusion (CVO) and combined TIPS and portal azygous disconnection for the treatment of portal hypertension and variceal bleedings.

METHODSThree hundreds and fifty-eight patients with portal hypertension were admitted because of variceal bleeding from July 1993 to May 2008. All patients were divided into 3 groups: 227 cases in group TIPS, 36 cases in TIPS and CVO group, 95 cases in combined TIPS and portal azygous disconnection group. The rates of successful operation, shunt patency, rebleeding, encephalopathy and survival were observed and compared by statistics methods.

RESULTSThere were 349 cases (97.5%) underwent successful surgery and 9 cases with failure surgery. The rates of occluded shunts, encephalopathy, rebleeding, and death in early periods were 2.5%, 31.8%, 4.7% and 9.0% respectively. The rate of encephalopathy and death in group with TIPS were higher than in group with combined TIPS and portal azygous disconnection (P < 0.01). The rate of encephalopathy and death were 41.2% and 24.7% in 85 cases with emergency TIPS. During the follow-up 1 - 15 years, the rate of patency shunts in 12 and 24 months after operation was 74.0% and 48.1% respectively. The rate of 1-year patency shunts in group with combined TIPS and portal azygous disconnection was higher than in group with TIPS, TIPS and CVO (P < 0.01 and P < 0.05). The rebleeding in group with TIPS was higher than in group with combined TIPS and portal azygous disconnection (P < 0.01), and the survival rate in group with TIPS was lower than in group with TIPS and CVO, combined TIPS and portal azygous disconnection (P < 0.01 and P < 0.01).

CONCLUSIONSTIPS is an efficient therapy for portal hypertension with CVO, combined TIPS and portal azygous disconnection can improve the results of TIPS for portal hypertension.
