Objective To investigate the outcomes of patients undergoing off-pump coronary artery bypass grafting (OPCABG) under morphine-fentanyl combined anesthesia. MethodsSeventy-two patients aged 41-64 yr undergoing OPCABG were randomly divided into 2 groups (n = 36 each): Ⅰ group morphine + fentanyl (group MF) and Ⅱ group fentanyl (group F). Anesthesia was induced with midazolam, etomidate, and vecuronium.Fentanyl 10-20 μg/kg was given iv when needed. The patients were mechanically ventilated after tracheal intubation. Anesthesia was maintsined with inhalation of 0.5%-2.0% isoflurane and intermittent iv boluses of vecuronium in both groups. Morphine 0.15 mg·kg-1·h-1 + fentanyl 8 μg·kg-1·h-1 were infused during operation in group MF, while in group F fentanyl 10 μg·kg-1·h-1 was infused. Morphine 0.75 mg/h was infused in group MF or fentanyl 10 μg/h in group F for postoperative analgesia after extubation. Recovery from anesthesia was assessed using a nine point (QoR) questionnaire. Pain was measured with VAS score and sedation with Ramsay sedation score ( 1 = fully awake, 6 = asleep, no response to verbal stimulus). The postoperative complications were recorded. ResultsQoR scores were significantly higher in group MF and in group F. The incidence of postoperative febrile reaction was significantly reduced in group MF. There was no significant difference in Ramsay sedation score and other postoperative complications between the 2 groups. ConclusionMorphine-fentanyl combined anesthesia is more beneficial for the prognosis in patients undergoing OPCABG compared with fentanyl combined anesthesia.

OBJECTIVE:To investigate sodium intake via drug used by hypertensive inpatients during hospitalization. METH-ODS:290 inpatients with hypertension were collected from vasculocardiology department of our hospital between Jan. and Oct. 2013. The types of sodium-containing drugs and sodium-intake during hospitalization were analyzed statistically. RESULTS:275 pa-tients with hypertension were prescribed 38 sodium-containing drugs(94.8%);82.7% were administered by iv gtt with a average drug treatment course of 6.7 days(average hospitalization days of 6.8 days). Solvent containing sodium such as 0.9% Sodium chlo-ride injection and Creatine phosphate sodium for injection were the most sodium donors. 43.3% patients’sodium intake exceeded upper limit of 2 g/day recommended by WHO. CONCLUSIONS:Hypertensive inpatients are prescribed too much sodium-contain-ing drugs,and less intravenous solutions and less adjuvant medicines should be took to decrease sodium intake. Only when prospec-tive benefit are greater than risk,the patients can be prescribed sodium-containing drug prescription.At the same time,manufacturers should annotate the content of sodium in package inserts,which is convenient for physicians to choose drugs.

Objective To analyze the characteristics of the common first attack of headache in patients with cerebral venous sinus thrombosis (CVST). Methods The clinical data of 51 patients who were diagnosed as CVST with MR venography (MRV)or DSA were collected retrospectively. The patients were divided into either a acute group (≤3 week,n= 32)or a chronic group (>3 weeks, n=19). Results (1)The age of onset of symptoms in these patients was 20 to 40 years,and most of them were females. Of all the first symptoms,headache ranked first,accounting for 84. 3%(43/51 );headache only accounted for 52. 9%(27/51 ),headache with other symptoms (ophthalmic symptoms, hemiplegia,and aphasia,etc. )accounted for 31. 4%(16/51 ),and other symptoms such as epilepsy, paralysis,and ophthalmic symptoms accounted for 15. 7%(8/51). (2)The proportion of headache only as the first symptom in the acute group was higher than that in the chronic group (65. 6% vs. 31. 6%,P<0. 05), and the proportion of chronic headache with other symptoms as the first symptom in the chronic group was higher than that of the acute group (P<0. 05). In addition,the proportion of the first symptom including ophthalmic manifestations in the chronic group was higher than that of the acute group (P <0.01 ). (3)Forty-three patients with headache,dull headache or distensible pain accounted for 72. 1%(31/43), thunderclap headache accounted for 11. 6%(5/43),and other kinds of headache accounted for 16. 3%(6/43),however,there were no significant differences about the types of headache between the two groups (all P>0. 05 ). Conclusion Young patients without previous history of migraine,especially women of childbearing age with sudden onset and progressive worsening headache,and the patients with idiopathic intracranial hypertension,CVST should be considered as an important possibility.

Objective To observe the effects of family cognitive training on patients with vascular cognitive impairment but without dementia.Methods Sixty patients with non-dementia type vascular cognitive impairment were divided at random into a group which received family cognitive training (30 cases) and a control group (30 cases).The 2 groups all took routine drugs and exercise.The family cognitive training group received cognitive training additionally.Before treatment and after 1 and 6 months of treatment,all of the patients of both groups were assessed using the mini-mental state examination (MMSE),the Montreal cognitive assessment (MoCA) and the modified Barthel index (MBI).Results After 1 month of treatment there was no significant difference between the 2 groups in any of the assessments.After6 months the scores on each item of the MMSE,MoCA and MBI had improved significantly more in the family cognitive training group than in the control group.Conclusion Family cognitive training is effective in treating non-dementia type vascular cognitive impairment.It can delay disease progression and improve cognitive function and ability in the activities of daily living.

To explore the anti-tumor proliferation activity of human interleukin-29 (hIL-29) variant and based on bioinformatics analyzed data of hIL-29, a mutant gene hIL-29(mut33,35) was amplified by site-directed mutagenesis and megaprimer PCR. The hIL-29(mut33,35) was inserted into an eukaryotic expression plasmid pPIC9K and successfully expressed in Pichia pastoris GS115. A recombinant variant protein (rhIL-29(mut33,35)) was purified from the ferment supernatant of the engineering GS115. To observe the antineoplastic activity of the variant rhIL-29(mut33,35), a CCK-8 reagent was used to detect the anti-proliferation effect. Results show that it has strong anti-proliferation effect when acted on liver cancer cell BEL7402, colon cancer cell HCT8 and gastric cancer cell SGC7901. The inhibition ratios of the three tumor cells were (30.99 ± 1.58)%, (22.47 ± 1.37)% and (32.05 ± 2.02)%, respectively. In high dose group, the anti-proliferation effect of the rhIL-29(mut33,35) was stronger than that of wild type rhIL-29 (P < 0.01). This indicates the variant rhIL-29(mut33,35) has potential development value for medicine.

To establish a new immune assay for Penicillic Acid (PA) from Penicillium cyclopium, we studied the synthesis of conjugated complete antigens for penicillic acid. PA was conjugated to bovine serum album (BSA) and ovalbumin (OVA) by 1-ethyl-3-(3-dimethyl-aminopropyl) carbodiimide hydrochloride (EDC). The artificial antigens PA-BSA and PA-OVA were identified by ultraviolet spectrometric scanning, SDS-PAGE and immunization. Results showed that the absorption peak of conjugation were different from that of the carrier protein alone and of the PA. The conjugated ratio of PA and BSA was 23.2:1 and that of PA and OVA was 10.4:1. Balb/c mice were immunized by the artificial antigen of PA-BSA, with PA-OVA as coating antigen. The average titer of antiserums was more than 12 800 by indirect ELISA. The obtained antigens offered a basis for developing immunoassay method.

Betulinic acid (BA), a pentacyclic lupane-type triterpene, has a wide range of bioactivities. The main objective of this work was to evaluate the hepatoprotective activity of BA and the potential mechanism underlying the ability of this compound to prevent liver damage induced by alcohol in vivo. Mice were given oral doses of BA (0.25, 0.5, and 1.0 mg/kg) daily for 14 days, and induced liver injury by feeding 50% alcohol orally at the dosage of 10 ml/kg after 1 h last administration of BA. BA pretreatment significantly reduced the serum levels of alanine transaminase, aspartate transaminase, total cholesterol, and triacylglycerides in a dose-dependent manner in the mice administered alcohol. Hepatic levels of glutathione, superoxide dismutase, glutathione peroxidase, and catalase were remarkably increased, while malondialdehyde contents and microvesicular steatosis in the liver were decreased by BA in a dose-dependent manner after alcohol-induced liver injury. These findings suggest that the mechanism underlying the hepatoprotective effects of BA might be due to increased antioxidant capacity, mainly through improvement of the tissue redox system, maintenance of the antioxidant system, and decreased lipid peroxidation in the liver.
