OBJECTIVE: To design and synthesize two kinds of allyl-substituted quercetin and investigate their anti-oxidation and anti-tumor activities in vitro. METHODS: The target compounds 1 and 2 were first synthesized from quercetin by hydroxyl protection, allylation,Claisen rearrangement and deprotection. The anti-oxidation and anti-tumor activities of the target compounds and intermediate products were evaluated by DPPH and MTT assay. RESULTS: Eight compounds were synthesized,including six intermediates and two target compounds,in which four were new compounds. All of them were confirmed by 1H-NMR,13C-NMR and LC-MS spectra. The anti-oxidation and anti-tumor tests showed that compounds 1,2,5,6,8 and 9 had anti-oxidation activities and compound 5 inhibited A549 lung cancer cell proliferation. Compound 9 could inhibit the proliferation of lung cancer A549 cells and HepG2 cells. CONCLUSION: The compounds with electron-donating groups have significant anti-oxidant activity. When acetyl and methyl ether groups are used as the protecting groups,the position of introducing allyl group to quercetin has obvious impact on the anti-tumor activity.

Objective To investigate the clinical outcomes of minimally invasive percutaneous nephrolithotomy(MPCNL)in the treatment of lower caliceal calculi.Methods We retrospectively re- viewed the clinical outcomes and complications of 33 patients who underwent MPCNL for lower caliceal cal- culi from March 2001 to April 2005.The average diameter of the calculi was 2.8 cm.Single tract nephrosto- my was performed in all 33 cases;among them renal access was obtained through a middle calyx in 10 cases and a lower calyx in 23.Nine cases had F14 renal access;and 24 cases,F16.Results Of 33 cases,28 (85%)achieved stone-free at 1 session.A second-look was needed in 3 cases due to intraoperative bleed- ing;ESWL,in 1 case with residual,calculi;no treatment,in 1 case with residual calculi＜4 ram.The mean operative time was 93 min;mean blood loss was 113 ml;mean hospital stay was 11 d.Blood transfusion was needed in 1 patient who suffered from hepatic cirrhosis preoperatively;another experienced severe bleeding 7 d after operation and was cured with hyperselective spongia gelatinosa embolization of the renal artery.Fol- low-up was available in 19 cases for 2-48 months,and no recurrence of renal calculi was noted.Conclu- sions Minimally invasive percutaneous nepbrolithotomy has advantages of safety,less invasion,and easy re- covery for the treatment of lower caliceal calculi.

Objective To evaluate the effects of serum procalcitonin (PCT)-guided antibiotic therapy in elderly patients with early-onset stroke-associated pneumonia (EOP).Methods Totally 179 eligible elderly patients with EOP were randomly devided into 2 groups:standard therapy group (standard group,n=88) and PCT-guided group (PCT group,n=91).Patients in standard group received antibiotics according to antibiotics guidelines in China by the treating physicians.Patients in PCT group were treated with antibiotics for 5 days,then the antibiotic treatment was based on serum PCT levels as follows:discouraged if PCT＜0.25 μg/L and encouraged if PCT≥0.25 μg/L.Length of hospitalization,duration of antibiotics,costs of hospitalization and antibiotics,clinical efficacy,andmortality,National Institutes of Health Stroke Scale (NIHSS) score and Barthel index (BI) on the 28th day were observed.Results There were no significant differences in clinical efficacy,mortality,NIHSS score and BI between the two groups on the 28th day [(85.7％ vs.86.3％),(8.8％ vs.7.9％),10.1 (7.8,16.2) vs.9.8 (6.0,15.5),60.1(42.5,82.3) vs.57.9 (39.2,84.8),respectively,all P＞ 0.05].The length of hospitalization,antibiotic duration,costs of hospitalization and antibiotics were lower in PCT group than in standard group [19 (10,38) d vs.26(17,42) d,10 (7,14) dvs.15 (6,21) d,3350 (2052,6163) yuanvs.10355 (6877,15421) yuan,7532 (4810,12116) yuan vs.5358 (3089,8144) yuan,respectively,all P＜0.05].Conclusions PCT guidance of antibiotic therapy is effective and safe for the treatment of early-onset stroke associated pneumonia in elderly patients.It can reduce the antibiotic duration and costs of hospitalization.

OBJECTIVETo explore the effect of Danggui Yinzi (DY) on delayed allergy in model mice with qi-blood deficiency syndrome (QBDS).

METHODSQBDS model was established in 48 Kuming mice of SPF grade by using reserpine and acetophenone hydrazine. Forty of them were then randomly divided into the model group, the loratadine group, the high dose DY group, the middle dose DY group, and the low dose DY group, 8 in each group. Another 8 in line with the same standard were recruited as a blank group. Mice in high, middle, and low dose DY groups were administered with DY concentrated solution at 60, 30, 15 g/kg by gastrogavage. Mice in the loratadine group were administered with loratadine solution at 1.66 mg/kg by gastrogavage. Equal volume of normal saline was administered to mice in the model group and the blank group by gastrogavage. All medication was given once per day for 1 successive week. Except those in the blank group, the rest mice were evenly smeared with 1% DNCB solution on the abdomen. Five days after skin allergy, 1% DNCB solution was smeared to right ear of all mice to stimulate allergic reaction. Mice in the blank group were smeared in the same way without allergenic reaction. The auricle swelling and the inhibition ratio were determined at 24 h after attack. Blood was collected from orbit and serum IgE level detected using double-antibody sandwich ELISA.

RESULTSCompared with the blank group, auricle swelling obviously increased and serum IgE level was obviously elevated in the model group (P < 0.01). Compared with the model group, auricle swelling obviously decreased and serum IgE level was obviously reduced in the 3 dose DY groups (P < 0.05, P < 0.01). Meanwhile, the auricle swelling degree was superior in high and middle dose DY groups to that in the loratadine group (P < 0.05). The inhibition ratio of auricle swelling was sequenced from high to low as 67.3% in the high dose DY group, 56.0% in the middle dose DY group, 48.1% in the low dose DY group, 47.3% in the loratadine group.

CONCLUSIONSDY could inhibit auricle swelling and lower serum IgE level. It also could inhibit delayed allergic reaction in model mice with QBDS to some extent.

OBJECTIVETo observe the regulatory effects of electroacupuncture with different acupoints combinations on blood lipid and atherosclerosis index (AI) in rats with hyperlipemia, so as to make a preliminary screening for the optimal acupoints combination for hyperlipemia.

METHODSOne hundred and five clean-grade SD male rats were randomly divided into 9 groups, including a normal group, a model group, a Quchi group, a Zhongwan group, a Fenglong group, a Quchi+Zhongwan group, a Quchi+Fenglong group, a Zhongwan+Fenglong group and a Quchi+Zhongwan+Fenglong group (three acupoints group), 17 rats in the normal group and 11 rats in the rest groups. The normal group was fed with normal diet, while the rest groups were fed with high-fat diet for 3 weeks to prepare the hyperlipemia model. All the rats were given unlimited water. After the establishment of model, the normal group was fed freely without any treatment; the model group was bundled and immobilized everyday; the rest groups were bundled, immobilized and treated with electroacupuncture at corresponding acupoints with disperse-dense wave, 20 min per time, once a day. After 4 weeks, the blood examples were collected from abdominal aorta to measure the total cholesterol (TC), triglyceride (TG), high-density lipoprotein (HDL-C) and low-density lipoprotein (LDL-C), and analyzed the AI in each group.

RESULTSAfter the treatment, TC, TG, HDL-C, LDL-C and AI in each acupuncture group were all lower than those in the model group (P<0.05, P<0.01). Compared with single acupoint group and the Quchi+Zhongwan group, the content of TC in the three acupoints group was lower (P<0.01). The differences of content of TG among each acupuncture group were not significant (all P>0.05). Compared with the rest 6 acupuncture groups, the content of HDL-C and AI in the three acupoints group were significantly different (all P<0.05). The content of LDL-C in the three acupoints group was decreased as compared with the Quchi group and the Zhong-wan group.

CONCLUSIONThe electroacupuncture at "Quchi" (LI 11), "Zhongwan" (CV 12) and "Fenglong" (ST 40) has more advantages on regulating the content of HDL-C and LDL-C as well as improving AI in hyperlipemia rats, and it has superior effects on blood lipid metabolism.

A series of isoindoline derivatives were designed, synthesized, and evaluated for their double inhibitory activities. All of them were new compounds, and their structures were confirmed by 1H NMR and HR-MS. Preliminary in vitro pharmacological tests showed that all compounds exhibited 5-HT or NE reuptake inhibition activity. Among the tested compounds, compound I-3 exhibited potent inhibitory activity against 5-HT and NE reuptake in vitro, and exhibited potent antidepressant activity in vivo. These compounds designed can be further optimized for finding more potent 5-HT/NE dual reuptake inhibitors and antidepressant candidates as well.

OBJECTIVE: To investigate the correlationship between the assessment of subjective and objective in patients with chronic(CRS) rhinosinusitis before and after FESS. METHOD: Seventy patients with CRS were objectively assessment of VAS and subjectively assessment including the Lund-Kennedy endoscopic scale and Lund-Mackay scale. All patients were followed up 1 year and repeated both the objective and subjective assessment. The correlationship among the different assessments were investigated and the scales of before and after FESS were compared. RESULT: There were positive correlation between the scale of VAS and Lund-Mackay(r = 0.866, P < 0.01), positive correlation between the scale of Lund-Kennedy and Lund-Mackay(r = 0.803, P < 0.01), and positive correlation between the scale of VAS and Lund-Kennedy (r = 0.912, P < 0.01) before the FESS. There were positive correlation between scale of VAS and Lund-Kennedy after 6 and 12 months of FESS with the r-value of 0.798 and 0.882 respectively. The scales of VAS including nasal obstruction, nasal discharge and head pain have positive correlation with the total scale of Lund-Kennedy with r-value of 0.691, 0.760 and 0.751 respectively. And the scales of VAS including hyposmia and general malaise have positive correlation with the total scale of Lund-Kennedy with r-value of 0.327, and 0.438 respectively. The scale of Lund-Mackay before has positive correlation with both the scale of Lund-Kennedy and VAS. CONCLUSION In patients with CRS, there were correlations among the scales of CT assessment, nasal endoscopic evaluation and VAS before FESS, and there were also correlations between the scales of CT assessment and nasal endoscopic evaluation after 6 and 12 months of FESS. It indicated that to evaluate the patients with CRS properly, the comprehensive assessment including subjective and CT and endoscopic scale should been applied in clinic.
