Objective To focus on the transitional nursing needs and its influencing factors of patients accepted transjugular intrahepatic portosystemic shunt (TIPS). Methods The study was conducted with a self-designed questionnaire involving 54 patients accepted TIPS. Also, in-depth semi-structured interviews were conducted among 10 patients. Results The total score of transitional nursing needs among patients accepted TIPS was (4.53 ± 0.48) points, which was in the relatively high lever. The multiple linear regression analysis showed that age, hepatic function and levels of venous ammonia were influence factors of transitional nursing needs among patients accepted TIPS (P<0.05). Conclusions The transitional nursing needs of patients accepted TIPS is urgent. Postoperative transitional nursing should be focused on younger, poor hepatic function and venous ammonia big change among patients accepted TIPS. Low-protein diet and the prevention of complications should be taken priority over all others.

Objective To investigate natural killer(NK) and NKT cells in acute pancreatitis(AP).Methods Changes of NK and NKT cells in peripheral blood of 86 AP cases were detected using muhiparameter flow cytometry.Results Compared with control group,the NKT cells decreased in AP patients (t =5.23,P =0.00),but NK cells didn't (t =-1.15,P =0.25).NKT cells in severe SAP and mnoderate MAP were lower than that in the control group (t =-3.92,P =0.00;t =4.84,P =0.00).There was no statistically significant difference of NK cells between MAP and the controls (t =-0.54,P =0.59),but NK cells in SAP group was obviously higher than that in control group (t =3.12,P =0.00).After one week treatment,NK cells significantly decreased (t =8.43,P =0.00).NKT cells were higher than control group (t =-4.44,P =0.00).Dynamic monitoring in AP patients found continuous declination in NK cells,and NKT cells experienced an increase before a falling.Conclusion Monitoring of NK and NKT cells can be used as an important index for the severity and response to treatment in acute pancreatitis.

Objective To study the physiological properties of a potassium channel in the basolateral membrane (BLM) of proximal tubule. Methods Nephrons were dissected from rat kidney under a stereoscopic microscope. The standard configuration for single channel tight seal patch clamp technique was used to record channel currents from the BLM. Results A kind of potassium channel with low conductance and inward rectification was easily recorded in the BLM of the proximal tubule. The channel current occurred spontaneously in 81% seals made on the BLM. In the patches, with no spontaneous channel activity, the channel current occurred when the pressure increased. In the inside out configuration, run down was present in channel activity. The open dwelling time constants of the potassium channel were 0.524 ms and 5.087 ms, while the closed dwelling time constants were 1.029 ms and 16.500 ms. Conclusion A type of potassium channels with low conductance, stretch sensibility and chemistry sensibility, presenting kinetic properties as two opening and two closing states, are widely distributed in the basolateral membrane of proximal tubule.

Objective To determine the expression of glial fibrillary acidic protein(GFAP) and vascular endothelial growth factor(VEGF) in the hippocampus of rats with Alzheimer's disease(AD), and to determine the effect of butylphthalide on them and its significance. Methods Sixty male adult rats were randomly divided into a model group, a Butylphthalide group, and a control group. AD models were established by injecting β-amyloid protein 1-42 into the hippocampus of rats. Sixty days later,the rats were sacrificed and both sides of the hippocampus were sectioned for immunohistochemistry. Results Positive cells of GFAP in the hippocampus of the model group increased and the expression of VEGF decreased statistically, compared with the control group(P<0.01). The positive cells of GFAP in the hippocampus of the butylphthalide group decreased and the expression of VEGF increased significantly, compared with the model group(P<0.05). Conclusion Butylphthalide may protect the neuron-vascular unit of the hippocampus of Alzheimer model rats by inhibiting the expression of GFAP and increasing the expression of VEGF.

This study pharmacokinetically examined the lovastatin sustained-release tablet and sustained-release capsule in Beagle dogs. An reversed-phase HPLC method was established for the determination of lovastatin in Beagle dog plasma. Pharmacokinetic findings were compared among three preparation(lovastatin sustained-release tablet, Tp; sustained-release capsule, TJ and conventional capsule). Our results showed that the pharmacokinetic parameters in 6 dogs after single-dose oral administration of three perparations were calculated. Tmax, Cmax and MRT revealed significant difference (P<0.05). Relative bioavailability was 111.5 +/- 16.9% (Tp) and 110.4% +/- 9.6% (Tj). The pharmacokinetic parameters in the 6 dogs after multiple-dose oral administration of three perparations, Tmax, Cmax MRT and DF had significant difference (P < 0.05); Cav, Cmin and AUC0-24 h displayed no significant difference (P>0.05). It is concluded that the lovastatin sustained-release tablet and sustained-release capsule are able to maintain a sustained-release for 24 h.

Euphorbia lathyris （Caper spurge） is a toxic and potent Chinese materia medica （T/PCMM）. This study sought a method for identifying five diterpenoids （Euphorbia factors LI-L3, L7a, and Ls） with the spectra of UV and mass, quantifying three diterpenoids L1, L2, and L8 in crude extracts of unprocessed and processed E. lathyris seeds by liquid chromatography/ electrospray ionization mass spectrometry （LC-ESI-MS）. The analysis was achieved on an Agilent Eclipse XDB-C18 column （4.6 mm× 150mm i.d., 5 μm） with an isocratic elution with a mobile phase consisting of water and acetonitrile at a flow rate of 0.25 mL/min at column temperature of 30 ℃ and UV detection was set at 272 nm. An ESI source was used with a positive ionization mode. The calibration curve was linear in the ranges of 9.9-79 μg/mL for Euphorbia factor Lb 3.8-30.5μg/mL for Euphorbia factor L2, and 1.0-20.6 μg/mL for Euphorbia factor LB. The average recoveries （n=6） of three diterpenoids were 98.39%, 91.10% and 96.94%, respectively, with RSD of 2.5%, 2.4% and 2.1%, respectively. The contents of the three diterpenoids in processed E. lathyris seeds were 3.435, 1.367 and 0.286 mg/g, respectively, which decreased more sharply than those in unprocessed E. lathyris seeds which were 4.915, 1.944 and 0.425 mg/g, respectively. The method is simple, accurate, reliable and reproducible, and it can be applied to control the quality of unprocessed and processed E. lathyris seeds.
