CONCLUSION: The established method has high specificity and can be used for the quality control of Qindan granule.

Objective To discuss the causes and the prevention measures of the complications occurred after interventional therapy for different type of Budd-Chiari syndrome (BCS). Methods Based on the type of BCS, the corresponding interventional management was adopted in 204 patients with BCS. The interventional procedures included PTA and stent placement of inferior vena cava (IVC), percutaneous transhepatic recanalization and dilation (PTRD) of hepatic vein, percutaneous transjugular or transinferior vena cava recanalization, dilation and stent placement of hepatic vein and transjugular intrahepatic portal-systemic stenting shunt (TIPSS). Results The successful rate of interventional therapy was 95.5% (21 / 22) for type Ia, 81.8% (9 / 11) for type Ib, 97.3% (109 / 112) for type IIa, 92.9% (13 / 14) for type IIb, 88.9% (8 / 9) for type Ⅲa, 100% (2 / 2) type Ⅲb, 92% (23 / 25) for type Ⅳa and 88.9% (8 / 9) for type Ⅳb BCS. The main complications occurred during or after the operation included acute cardiac insufficiency (n = 2), pulmonary arterial embolization (n = 4), disseminated intravascular coagulation (n = 1), extravasation of contrast medium (n = 3), arrhythmia (n = 2), and cardiac tamponade (n = 1). Conclusion Interventional therapy is simple, safe and effective for the treatment of BCS, but its indications should be strictly considered and all kinds of effective prevention measures should be taken to avoid or to reduce the possible complications.

Objective To investigate the effects of captopril on intubation response and the mechanism. Methods Thirty ASA Ⅰ - Ⅱ patients aged 25-60 yr, weighing 45-70 kg, scheduled for elective surgery under general anesthesia with tracheal intubation and mechanical ventilation were randomly divided into 2 groups: captopril group ( n = 15) and control group ( n = 13) . Premedication consisted of intramuscular phenobarbital 0.2 g and atropine 0.5 mg. In captopril group, captopril 0.3-0.35 mg?kg-1 was injected intravenously 10 min before induction while in control group normal saline 10 ml was given instead. Anesthesia was induced with droperidol 0.05 mg?kg-1 , fentanyl 1 ?g?kg-1 , thiopentone 5-6 mg?kg-1 . Intubation was facilitated with succinylcholine 1.5 mg ? kg-1 . Laryngoscopy and tracheal intubation was successfully performed within 30 seconds. Mechanical ventilation was started and enflurane inhalation was begun and maintained at 2.1 % , SBP, DBF, HR, EGG and SpO2 were continuously monitored. Blood samples were taken from peripheral vein before induction (T0 ) , at intubation (T1 ), 1-1.5 min (T2) and 5 min (T3) after intubation for determination of plasma concentrations of angiotensin- Ⅰ (A 1 ), angiotensin- Ⅱ (A Ⅱ ), aldosterone (ALD), noradrenaline (NE), adrenaline (E), atrial natriuretic polypeptide (ANP) and thromboxane B2(TXB2) .Results (1) In captopril group SBP, DBF, HR, and heart rate-systolic BP product (RPP) remained unchanged at intubation, while in control group the parameters were significantly increased at T1 or T2 as compared with the baseline values ( P

ObjectiveTo study the characteristics in negative energy balance in different-aged patients with metabolic syndrome (MS) and come out with nursing countermeasures.Methods Twenty-four hour dietary data reviewing and the international physical activity questionnaire were used to investigate energy intake and consumption among 384 MS patients.The fat content,fat percentage and lean body mass were measured by the human body composition analyzer.Body mass index (BMI),waist/height,fat percentage,lean body mass,energy intake and energy consumption were compared between different ages and sexes.Results In the group aged over 51 years,the waist/height of female MS patients was significantly smaller than their male counterparts (P<0.05).For all groups of different ages,the percentage of fat in the female patients was significantly larger,their lean body mass was less(P<0.01), their intake of energy was significantly lower than that of the males (P<0.05).The intake of energy among the male patients at the group aged 21~30was significantly larger than the males of other age groups and so it was with the energy intake of the males aged 21-70 years as compared to the males aged 71~80 years (P<0.05).Conclusion Education on disease knowledge should be strengthened among healthy people so as to realize the negative energy balance based on the rate of waist/height,body composition,energy intake and energy consumption,which is of great significance for the prevention and control of metabolic syndromes.

Objective To investigate the effect of asymptomatic hyperuricemia after renal transplantation on renal function of the grafts.Methods The follow-up data were retrospectively collected and analyzed in 144 patients with renal transplantation from January 2010 to March 2015.The patients were classified into three groups according to the level of serum uric acid (SUA):group A (normal group),group B (asymptomatic hyperuricernia with average SUA less than or equal to 360 μmol/L after treatment),and group C (asymptomatic hyperuricemia with average SUA greater than 360μmol/L after treatment).The renal function indexes such as serum creatinine (SCr) and estimated glomerular filtration rate (eGFR) were compared among three groups from 12 to 48 months after transplantation.Results The SCr and eGFR showed no significant difference between group A and group B at 12th month (P＞0.05),but ther are superior than Group Ⅲ (P＜0.05).Conclusion After renal transplantation,asymptomatic hyperuricemia can lead to impaired renal function,and there are no significant differences in renal function between renal transplant recipients with normal SUA levels after treatment and those without hyperuricemia.

Objective To investigate the effects and mechanism of remifentanil on renal ischemia/reperfusion(IR) injury via mediating Fas apoptosis signal pathway in rats.Methods Sprague-Dawley rats were divided into 3 groups (n =20 each) by using the random number table method:sham operation group (S group),IR control group (IR group),experimental group (Rgroup).The renal IR model was prepared by clamping the bilateral renal arteries for 45 min followedby reperfusion in IR group and R group.In R group,remifentanil was infused at 1.0μg·kg-1 ·min-1 via the tail vein starting from 15 min before ischemia until 30 min of reperfusion.In S group and IR group,the same volume of physiological saline was given.At 15 min before ischemia and at 3 h,12 h,24 h of reperfusion,the renal tissue samples were obtained for detecting the apoptosis rate by flow cytometry,determining the level of Fas mRNA expression by RT-PCR,the level of caspase-8 and caspase-3 activation by Western blotting,and scoring the number of kidney tubules injury by Paller'method.Results In IR group,the renal tubular injury score,the apoptosis rate,the expression of Fas mRNA and the activation of caspase-3 in renal tissue increased at 3 h after reperfusion,and those continued to increase at 12 h after reperfusion and reached the peak at 24 h after reperfusion (P＜0.01),and the activity of caspase-8 increased at 3 b,reached the peak at 12 h after reperfusion and decreased at 24 h after reperfusion (P＜0.01).As compared with S group,the renal tubular injury score,apoptosis rate,the expression of Fas mRNA and the activation of caspase-3 at 3 h,12 h and 24 h of reperfusion and the activation of caspase-8 at 12 h,24 h of reperfusion were all increased in IR group and R group (P＜0.05 or 0.01).As compared with IR group,the renal tubular injury score,apoptosis rate,the expression of Fas mRNA and the activation of caspase-8 and caspase-3 at 3 h,12 h and 24 h of reperfusion were decreased in R group (P＜0.05 or 0.01).Conclusion Remifentanil inhibits cell apoptosis and alleviates renal IR damage by reducing the expression of Fas receptor and the activation of caspase-8 and caspase-3,and regulating the apoptotic signal pathway of Fas.

OBJECTIVE: The medicinal mushroom Sanghuangporus vaninii produces pharmaceutically valuable hispidin polyphenols in natural habitats. However, due to the slow growth in nature, S. vaninii grown in the field (sclerotia) is not reliable for pharmaceutical purposes. Although higher biomass of fungal mycelia can be obtained in submerged cultures, the accumulation of hispidin polyphenols is rare. METHODS: In this study, the polyunsaturated fatty acids (PUFAs), linoleic acid (LA), linolenic acid (ALA), and methyl jasmonate (MeJa) were employed as the stimulant agents to coordinate the accumulation of biomass and hispidin polyphenols in its submerged cultures. RESULTS: The addition of LA and ALA promoted the mycelial accumulation, while the addition of MeJa inhibited the growth of S. vaninii concomitant with reduced total polyphenols. UPLC-Triple-TOF-MS analysis revealed an increased production of hispidin, phellinstatin, pinnilidine, and its derivatives upon the addition of LA and ALA, and hypholomine B and its isomer, 3,14'-bihispidinyl, and phelligridin E upon the addition of MeJa on day 13. Intriguingly, total polyphenols from the MeJa-supplementing cultures harbored a high capacity in scavenging free radicals. Chemical structural analysis showed that hispidin polyphenols had higher antioxidant activity due to more hispidin moieties induced by MeJa. CONCLUSION The supplement of PUFAs affects the synthesis and composition of hispidin polyphenols in S. vaninii. Our results provide a possibility to coordinate the production of hispidin polyphenols via submerged cultures of S. vaninii.
