OBJECTIVE Tostudytheeffectofeffectivefractions(EFC)frommodifiedSimiaoWan (MSW)onthelevelofuricacidinhyperuricemicratsandinvestigatethemechanism.METHODS Two types of hyperurice mic models were established.A persistant hyperurice mic model was prepared by giving rats oxonic acid 200 mg·kg -1 and feeding the m with hypoxanthine.The models were ig given with modified Simiaowan (MSW)50 g·kg -1 or EFC 1 2.5,25 and 50 g·kg -1 consecutively for 5 d.The models were treated with MSW or EFC 50 g·kg -1 for 3 d.After the final treatment,the uric acid concen-trations in seru m and urine were determined by an auto matic bioche mistry analyzer.The activity of xan-thine oxidase (XOD )in the serum and liver was determined by enzymic colorimetric method.The activity of purine nucleoside phosphorylase (PNP)and uricase was detected by spectrophotometry. RESULTS Comparedwithnormalcontrolgroup,theserumlevelofuricacidinbothmodelgroupswas remarkably increased(P<0.01 ).Compared to model control group,MSW 50 g·kg -1 and EFC 12.5, 25 and 50 g·kg -1 significantly reduced the serum level of uric acid(P<0.05,P<0.01 ),but increased the activity of erythrocyte PNP(P<0.01 )in the oxonic acid potassium-induced hyperuricemia rats. MSW 50 g·kg -1 and EFC 50 g·kg -1 elevated the activity of liver uricase in the nicotinic acid-induced hyperuricemia rats(P<0.05).EFC 50 g·kg -1 also significantly decreased the serum XOD activity of hyperuricemicrats.CONCLUSION EFCsignificantlyinhibitstheserumlevelofuricacidinhyperurice-mic rats,which might involve down-regulation of protein levels of serum XOD to inhibit the production of uric acid and activation of uricase to pro mote the deco mposition of uric acid.

Objective To explore the clinical significance of prenatal diagnosis for absence of fetal cavum septum pellucidum (CSP) by ultrasonography. Methods The ultrasonographic characteristics were retrospectively analyzed in 63 fetuses, whose CSPs were not detected in prenatal two and three dimensional ultrasonography in Nanjing Medical University Affiliated Suzhou Hospital. Results In 63 fetuses with absent CSP, the related malformations included:(1) Five cases were diagnosed as agenesis of corpus callosum (ACC, including four complete ACC and one partial ACC);(2) Twenty-seven cases were diagnosed as holoprosencephaly (HPE, including 18 alobar HPE, ifve semilobar HPE and four lobar HPE);(3) One case was diagnosed as schizencephaly;(4) Two cases were diagnosed as porencephaly;(5) Five cases were diagnosed as hydranencephaly;(6) Twenty-three cases were diagnosed as severe hydrocephalus, among which ifve cases were caused by aqueductal stenosis and the other 18 cases were caused by open spina biifda (Chiari Ⅱ malformation). These absent CSP fetuses had other abnormalities including one case of Dandy-Walker Malformation, one case of Dandy-Walker Variation, 14 cases of median cleft lip, ifve cases of single naris, two cases of proboscis nose, three cases of talipes foot and four cases of single umbilical artery, etc. These 63 cases were all followed up after prenatal ultrasonography but 4 cases were missed and one case of septo-optic dysplasia was misdiagnosed as lobar HPE. The diagnoses of other 58 fetuses by ultrasonography were conifrmed by follow up. Conclusions CSP is considered as an essential part in prenatal evaluations of the fetal central nervous system during second-and third-trimester. Absence of CSP is always accompanied with an extremely wide spectrum of fetal neuroanatomic malformations, including prosencephalon diseases, intracranial midline anomalies, etc. Prenatal ultrasonography is the best choice for the observation of CSP.

OBJECTIVETo study the effect of acupuncture on skeletal muscle endurance in rats as a pre-games assistant training.

METHODSThirty male SD rats were randomly divided into 3 groups: control, model and acupuncture group. Acupuncture group was treated at "Dazhui" (GV 14), "Housanli" (ST 36) by twisting mild reinforcing-reducing method for 20 min, no interventions were added on control and model group. Muscle strength was detected in three groups under anaesthetic (after model established in model group, after model established and treated in acupuncture group). Averaged change percentage of mean skeletal muscle endurance (P(m)) and averaged maximum percentage of skeletal muscle endurance (P(max)) were evaluated.

RESULTS(1) 10P(m) in model group decreased more than acupuncture group statistically (P < 0.05); 20P(m), 30P(m) and 40P(m) in model group decreased significantly compared to those in control group and acupuncture group (P < 0.05, P < 0.01). (2) Changes of 10P(max) in acupuncture group was much less than in model group (P < 0.05); changes of 20P(max), 30P(max), 40P(max) and 50P(max) decreased more in model group than in acupuncture group and control group (P < 0.01, P < 0.05).

CONCLUSIONAs an assistant training method, acupuncture can postpone descending point of muscle strength endurance to delay sport fatigue.

OBJECTIVETo investigate the clinicopathological features, diagnosis, treatment and prognosis of primary clear cell carcinoma of the liver (PCCCL).

METHODSThe clinicopathological data of 24 cases with pathologically proven PCCCL in the First Affiliated Hospital of Guangxi Medical University from May 1996 to December 2003 were collected and analyzed.

RESULTSThere were 21 males and 3 females in this group, with an average age of 46 years (range: 30 approximately 78 years). HBV infection was detected in 83.3%, and AFP expression was found in 75.0% of them. Of the 24 cases, 28 tumors were found with an average size of (6.64 +/- 5.54) cm. Liver cirrhosis was found in 75.0% of the patients. Macroscopic and microscopic tumor thrombi were found in 20.8% and 29.2%, respectively. Lymph node metastasis was found in 4.2% of the patents. The 1-, 3-, and 5-year overall survival rates of the 24 cases were 75.0%, 41.7% and 27.8%, respectively, with a median survival time of 29 months.

CONCLUSIONThe clinical characteristics of primary clear cell carcinoma of the liver are similar to that of common hepatocellular carcinoma. It is difficult to be diagnosed preoperatively and final diagnosis depends on pathological examination. Surgical resection is an effective way to achieve favorable treatment outcome and even long-term survival.

Objective:To investigate the long-term death of patients with ischemic stroke and its influencing factors.Methods:Based on the data of patients with ischemic stroke in the multi-center oral fibrinogen-lowering drug secondary prevention database, the follow-up patient information and the cause of death were registered through the epidemiological investigation method, and then compared with the baseline data of patients in the original database.Results:A total of 278 patients completed the follow-up, and 166 were in lumbrokinase group and 112 were in control group. There were 124 deaths (44.6%) within 10 years, of which 92 (74.2%) were vascular deaths. In the lumbrokinase group, 74 patients (44.6%) died of all causes and 55 (33.1%) died of vascular diseases; in the control group, 50 (44.6%) died of all causes and 37 (33.0%) died of vascular diseases. Cox proportional risk model analysis showed that lumbrokinase treatment had no significant effect on the 10-year survival rate of patients with ischemic stroke. The analysis of death influencing factors showed that the baseline international normalized ratio (INR) was significantly associated with the 10-year non-vascular death risk of patients (hazard ratio [ HR] 1.98, 95% confidence interval [ CI] 1.21-3.25; P=0.006). The greater the decrease of tissue plasminogen activator (tPA) within half a year, the lower the 10-year all-cause mortality risk ( HR 0.94, 95% CI 0.90-0.99; P=0.011); the greater the decrease in INR within one year , the lower the 10-year vascular death risk ( HR 0.41, 95% CI 0.17-0.96; P=0.040); the greater the decrease of D-dimer within one year , the higher the risk of the 10-year vascular death ( HR 1.37, 95% CI 1.02-1.83; P=0.034). The greater the decrease of INR in patients with ischemic stroke within one year, the higher the 10-year non-vascular death risk ( HR 2.15, 95% CI 1.29-3.59; P=0.004). Conclusions:The 10-year mortality rate of patients with ischemic stroke is higher, and about 3/4 are vascular deaths. The fibrinogen-lowering treatment in the acute stage has no significant effect on the 10-year all-cause mortality of patients with ischemic stroke. The greater the decrease of tPA in half a year, the lower the all-cause mortality; the greater the decrease of D-dimer level at baseline and within 1 year, the higher the 10-year vascular death; the greater the decrease of INR at baseline and within 1 year, the higher the 10-year non-vascular death risk.

Objective:To compare the effects of staged percutaneous coronary intervention(PCI)after emergency PCI and emergency culprit-only PCI on clinical outcomes of elderly patients with ST-segment elevation myocardial infarction(STEMI)and multivessel disease.Methods:A retrospective analysis was performed on 389 elderly patients with STEMI and multivessel lesions, aged ≥70 years and within 12 h of onset, admitted to the Clinical College of Thoracic Medicine, Tianjin Medical University, between January 2014 and September 2019.According to different revascularization strategies, enrolled patients were divided into the culprit-only PCI group(79.18%, 308)and the staged PCI group(20.82%, 81). Kaplan-Meier analysis and the Cox proportional hazards regression model were used to compare the incidences of major adverse cardiac and cerebrovascular events(MACCE), all-cause death, cardiac death, recurrent myocardial infarction, stroke and ischemia-driven revascularization between the two groups and to evaluate the effects of different revascularization strategies on MACCE and all-cause death.Then subgroup analysis was performed.Results:During a 56-month follow-up, 131 patients developed MACCE and 96 patients died.Compared with the culprit-only PCI group, the staged PCI group had a lower risk of MACCE( HR: 0.404, 95% CI: 0.227-0.716, P=0.002), all-cause death( HR: 0.354, 95% CI: 0.171-0.730, P=0.005), cardiac death( HR: 0.363, 95% CI: 0.157-0.838, P=0.018), and recurrent myocardial infarction( HR: 0.229, 95% CI: 0.055-0.953, P=0.043). There was no significant difference in the incidence of stroke or ischemia-driven revascularization between the two groups( P>0.05). The reduced risk with staged PCI for MACCE and for all-cause mortality persisted in all subgroups.Multivariate Cox proportional hazards regression revealed that, after adjusting for confounding factors, staged PCI was an independent protective factor for MACCE( HR: 0.44, 95% CI: 0.239-0.815, P=0.009)and for all-cause death( HR: 0.390, 95% CI: 0.90, P=0.020). Conclusion:Compared with culprit-only PCI, staged PCI can significantly improve the long-term prognosis of elderly patients ≥70 years with STEMI and multivessel disease within 12 h of onset.

Objective To investigate the expression of peroxisome proliferator-activated receptors (PPARs) α/δ/γ protein and the effect of berberine on them in diabetic rat kidney.Methods Type 2 diabetic rats were induced by injection (ip) with streptozotocin 35 mg·kg1 and feeding with a high-carbohydrate/high-fat diet for 16 weeks.From week 17 to 32, diabetic rats were given low, middle, high-dose berberine 75, 150, 300 mg×kg-1, fenofibrate 100 mg×kg1 and rosiglitazone 4 mg×kg-1, respectively.The expression of PPARα/δ/γ protein in kidney were detected by immunohistochemistry.Results The expression of PPARα and PPARδ protein in the kidney of diabetic rat, which were significantly higher than that of the control one (P＜0.01), while PPARγ expression was obviously lower than that of the control one (P＜0.01).The expression of PPARα and PPARδ in in diabetic kidney were increased notably after middle-dose, high-dose berberine and fenofibrate treatment (P＜0.01);middle-dose, high-dose berberine and rosiglitazone treatment significantly reduced PPARγ expression (P＜0.01).Conclusion Berberine can restore the disturbed PPARα/δ/γ protein expression in diabetic rat kidney.
