Objective To explore the influence of fluid management and prognosis guided by goal direction on patients undergoing gastrointestinal surgery.Methods Eighty ASA grade Ⅰ-Ⅲ,consecutive consenting patients undergoing gastrointestinal surgery were divided into observation group (40 patients)and control group (40 patients) by random digits table method.The intraoperative fluid management in control group was based on central venous pressure(CVP),and kept CVP at 8-10 mmHg(1 mmHg =0.133 kPa).The intraoperative fluid management in observation group was based on stroke volume variation (SVV),and kept SVV at 10 ％-12％.The operation time,intraoperative and postoperative 3 d fluid management,time of defecation and exhaust,time of full or semi-liquid diet,length of stay in hospital,rate of complications after operation for 48 h between two groups were compared.Results The volume of total fluid,colloid solution and crystalloid solution received during operation in observation group were significantly lower than those in control group[(2 686.0 ± 977.5) ml vs.(4 837.5 ± 1 566.0) ml,(792.4 ± 197.6) ml vs.(1 284.6 ± 356.7)ml,(1 894.9 ± 460.4) ml vs.(3 569.9 ± 1 318.7) ml] (P ＜ 0.05).The time of semi-liquid diet,length of stay in hospital in observation group were significantly lower than those in control group [(171.1 ± 45.3) h vs.(235.8 ±89.5) h,(11.4 ±1.8) d vs.(14.7 ±4.9) d] (P＜0.05).The time of full liquid diet,time of defecation and exhaust between two groups had no significant difference(P ＞ 0.05).The rate of complications between two groups had no significant difference(P ＞ 0.05).Conclusion Compared with monitoring CVP,the fluid management based on SVV can decrease the fluid volume during operation and shorten the length of stay in hospital.

Objective: To observe the therapeutical effects of Lipo PGE_ 1 in the treatment of diabetic peripheral neuropathy. Methods: 42 cases of type 2 diabetes patients with diabetic peripheral neuropathy were recruited and were divided into two groups at random:therapy group treated with Lipo PGE_ l and control group treated with Vitamine B_ 1 and Vitamine B_ l2 . Results: After a treatment of 20 days,symptoms such as pain,numbness and hypoesthesia in cases of therapy group had been improved at different degrees.Examination of Neuroelectrophysiology indicated an increase of sensory nerves conduction velocity and motor nerve conduction velocity.The effects of therapy group outweighed that of control group. Conclusion: Lipo PGE_ 1 can significantly relief the symptoms of diabetic peripheral neuropathy and increase nerve conduction velocity.The mechanism of action may involve improvement of blood-supply of nerve by vasodilatation and inhibition of platelet aggregation that caused by PGE_ l .

AIM: To study the effect of tissue kallikrein gene (HK) treatment on blood pressure in type 2 diabetic rats and its mechanism. METHODS: Male Wistar rats were injected with low dose streptozotocin and fed with diets enriched in fat and sugar to form type 2 diabetic model. Recombinant adeno-associated viral vectors (rAAV)-mediated HK gene (HK group) or LacZ gene (LacZ group) was introduced to the diabetic rats. The systolic blood pressure was measured every 2 weeks. The acetylcholine (Ach)-dependent vasodilation response, the synthesis of nitric oxide (NO), the expression of endothelin-1 (ET-1) and endothelin-A receptor (ET_A-R) in the aorta were detected. RESULTS: (1) Systolic blood pressure was significantly higher in diabetic rats than that in normal control rats. In HK group, systolic blood pressure was significantly reduced within 2 weeks after injection with rAAV?HK, reached near normal levels at 4 weeks and kept until the experiments ended (16 weeks). (2) In LacZ group, Ach-dependent vasodilation response of isolated aorta was markedly decreased than that in HK group (P

Objective:To determine whether the immortalized human odo nt oblast-like cell line hTERT-hOd-l has transformed phenotype. Methods: The tumorigenicity, anchorage-independent growth, serum dependence and contact inhibition of the immortalized human odontoblast-like cell line hTERT- hOd-l were observed during continuous culture in vitro. Results: The cells showed to be nontumorigenic in nude mice, and to have no anchorag e-independent growth. The cells maintained the normal serum dependence and cont act inhibition. Conclusion:hTERT-hOd-l is a normal cell line w ithout obvious transformed phenotype.

This article discusses the functions of massage in acupuncture treatment and argues that massage acts to diagnose diseases, locate acupoints, activate meridian qi before acupuncture treatment,protect healthy qi, dispel pathogenic factors, promote qi arrival and movement during acupuncture treatment, warm and nourish the body, and further promote qi movement and eliminate pathogenic factors after acupuncture treatment. Therefore, massage complements with acupuncture and becomes an essential method in acupuncture treatment.

Objective To establish the characteristic biothermokinetic methods in different extract fractions of Radix Isatis using Escherichia coli as model bacteria under biothermodynamics. MethodsMicrocalorimetry was used to obtain the characteristic metabolic growth power-time curves and biothermodynamic parameters of bacteria affected by different extract fractions of Radix Isatis, and evaluate the differences among the different extract fractions of Radix Isatis. Results Different extracting fractions of Radix Isatis could inhibit or promote the growth and metabolism of E. coli in different levels. Water-extract fractions and residues could promote its growth while organic solvent extract fractions did the opposite. Furthermore, with the decline of the solvent polarity, the inhibiting rate of organic solvent extract fraction was decreased and the generation time of bacteria was prolonged. There were steady and distinct differences among the different extract fractions in the characteristic metabolic growth power-time curves, such as the maximum power value's decrease and peak time's delay of water-extract fraction and residue, the specific power enhancement in later stage of organic solvent extract fraction. ConclusionMicrocalorimetry is a new and useful mean for the study on the biothermodynamic parameters and characteristics of Radix Isatis which can be helpful to investigate the other models using microcalorimetry.

OBJECTIVETo investigate the dosage-efficacy/toxicity relationship of prepared rhubarb, in order to explore the bidirectional effects in hepatoprotection and hepatotoxicity of prepared rhubarb and the objective authenticity for attenuating toxicity by processing.

METHODNormal and pathological animals were adopted simultaneous to investigate the effect of total extracts from prepared rhubarb within a high dose range (2.0, 5.4, 14.7, 40.0 g x kg(-1) x d(-1)) on normal state, biochemical index and histopathology of experimental animals. The factor analytic approach was used to analyze the dosage-efficacy/toxicity relationship of prepared rhubarb.

RESULTThe factor analytic approach was used to extract two common factors from the nine biochemical indexes. The firs common factor was mainly dominated by HA, LN and TGF-β1, and could be explained as fibrotic factors. The second common factor was mainly dominated by ALT, AST and ALP, and could be explained as cellular factor. The results of the factor analysis suggested that prepared rhubarb showed significant bidirectional effects in hepatoprotection and hepatotoxicity, which could protect liver in CC14 injured chronic hepatic injury, but had a certain hepatotoxic effect to normal animals. The pathological examination showed consistent results with the factor analysis. Under comparable dosages, prepared rhubarb showed a stronger liver protecting effect than crude rhubarb, with a lower toxicity.

CONCLUSIONAlthough prepared rhubarb has a certain hepatotoxic effect to normal animals, it has also a significant therapeutic effect to animals with liver injury. The results proved the symptom-based prescription theory and the scientificity of the symptom-based medication. The symptom-based prescription theory is important to correctly realize the dosage-efficacy/toxicity relationship of traditional Chinese medicines and guide the symptom-based medication.

Gene expression exhibits temporal and spatial patterns to response environmental changes and growth cycle. Gene expression is under strict control at different levels among which control at transcription level is the predominant mode, especially in prokaryotes. In this review, we summarized the new developments of methods used in transcriptional studies, including modifications and improvements of the classic methods, such as gel-shift assay, DNA foot printing, and in vivo reporter system. In addition, we introduced examples to apply new methods, such as surface plasmon resonance (SPR) and isothermal titration calorimetry (ITC) to characterize protein-DNA, ligand-protein, and ligand-protein-DNA interactions. The collection of these methods and their application could guide and accelerate relevant studies.
