Objective To observe the therapeutic effect of single lower limb traction plus massage for the lumbosacral tunnel syndrome.Methods The selected 80 candidate patients were divided into the observation group with 38 patients and treatment group with 39 patients. The observation group received single lower limb traction plus massage and the treatment group received pelvic traction plus massage. Both groups therapy last 5 days, The Japanese orthopaedic association scores (JOA) was evaluated for subjective symptoms, signs, functional activity and bladder function score. The therapeutic effect was evaluated.Results The total effective rate (94.7% vs. 82.1%;χ2=12.160,P=0.007) in the observation group was significantly higher than that in the control group. O, The scores of JOA at one week after treatment (20.2 ± 2.0 vs. 18.3 ± 2.8;t=3.419, P<0.01) and two weeks after treatment (24.4 ± 1. 4vs. 22.6 ± 3.0;t=3.359,P<0.01) in the observation group were significantly higher than those in the control group.Conclusions The single lower limb traction plus massage can improve the clinical symptoms of patients with lumbosacral tunnel syndrome, and be superior to the pelvic traction plus massage.

OBJECTIVETo explore action mechanism of electroacupuncture (EA) at "Fenglong" (ST 40) for treatment of hyperlipidemia.

METHODSForty SPF-grade SD rats were randomly divided into a normal group (group A), a model group (group B), a model diet-control group (group C), a model + EA group (group D) and model diet-control + EA group (group E), 8 cases in each one. The rats in group A were fed with normal diet continuously while those in the rest 4 groups were fed with high-fat diet to establish hyperlipidemia model. Afterwards, the rats in group C and group E were fed with normal diet, while EA at "Fenglong" (ST 40) was applied in group D and group E, 30 min per time, once a day. After 28 days of treatment, macrophage was collected in each group. Oil red O-staining was applied to detect the formation of foam cells, and enzyme-linked immunosorbent assay (ELISE) was adopted to measure the contents of total cholesterol (TC) in macrophage and analyze the rate of cholesterol efflux.

RESULTSThe counts of positive cells of oil red O-staining and the contents of TC in the group B, group C and group D were significantly increased compared with those in the group A (all P < 0.01). The counts of positive cells and contents of TC in the group C, group D and group E were significantly clecreased compared with those in the group B (all P < 0.01), and the decline in group D was more obvious than that in the group C (all P < 0.01). Compared with group C and group D, the counts of positive cells and contents of TC in the group E was obviously decreased (all P < 0.01), which was not statistically different from group A (P > 0.05). In the meantime, compared with group C, the rate of cholesterol efflux in group D and group E was significantly increased (both P < 0.01), and the rise in group E was more obvious than that in the group D.

CONCLUSIONThe electroacupuncture at "Fenglong" (ST 40) could significantly prohibit the transformation of macrophage into foam cell and increase rate of cholesterol efflux in macrophage, which could prevent and reverse the formation of foam cell and play an essential role in treating hyperlipidemia and stopping it from developing into a further level.

Objective To explore the association of Gly71Arg mutation in gene of bilirubin uridine 5'-diphosphate-glucuronosyltransferase(UGT1A1)and neonatal jaundice in Beijing city Han population.Methods The genotypes and alleles of the Gly71 Arg polymorphism for UGT1A1 gene were identified by polymerase chain reaction-restricted fragment length polymorphism assay in infants of Beijing city Han population of China,including 96 infants with neonatal jaundice[serum bilirubin(307.06?38.5)?mol/L,indirect bilirubin(292.9?35.9)?mol/L] and 101 healthy control infants [serum bilirubin(131.2?42.1)?mol/L,indirect bilirubin(126.3?39.7)?mol/L].The genotypes and allele frequencies of the polymorphism were compared between infants with neonatal jaundice group and healthy infant group(control group).The effect of polymorphism in infants with neonatal jaundice group on serum bilirubin level were analyzed.Results There were significant differences in genotypes distribution in Gly71Arg polymorphism for UGT1A1 gene between the 2 groups(?2=9.47 P=0.002).Compared with control group,neonatal jaundice group had significantly higher Arg allele frequency in the polymorphism for UGT1A1 gene(?2=10.34 P=0.001).There were independent effects of Gly71Arg mutation in the gene on serum bilirubin level in neonatal jaundice group,at the carriers of homozygote of the Arg allele of Gly71Arg polymorphism had higher serum bilirubin levels compared to carriers of heterozygote of the Arg allele of the polymorphism and non-carriers of the Arg allele of the polymorphism(Pa

Eleven old male patients with hyperuricemia were collected ( hyperuricemia group,65-90 years old ).10 healthy middle-aged males ( middle-aged group,30-40 years old) and 10 healthy old males ( older group 60-70 years old ) with normal blood uric acid level were used as controls.All of the subjects were given low purine content diet ( 250 mg/d ) for 3 days followed by high purine content diet ( 800 mg/d ) consecutively for another three days.The samples of fasting blood and 24 h urine were collected for assay.The results showed that there were no significant changes of serum uric acid ( UA ) concentration in three groups after low purine content diet.But the levels of serum UA in three groups all increased significantly after high purine content diet,and the change was higher in hyperuricemia group than middle-aged group [ ( 507.7 ± 108.1 vs 378.9 ± 80.1 ) μmol/L,P＜0.05 ].24 h urine uric acid excretion in three groups was all significantly decreased after low purine content diet and increased after high purine content diet.After high purine content diet,24 h urine uric acid was lower in hyperuricemia group than middle-aged group [ ( 2.99 ± 1.21 vs 3.62 ± 1.02 ) mmol/24 h,P＜0.05 ].Blood urea nitrogen levels in all subjects decreased after low purine content diet and increased after high purine content diet ( P＜0.05 or P＜0.01 ).Creatinine clearance rate in hyperuricemia group was decreased after high purine content diet compared with baseline [ (75.3 ± 20.3 vs 80.7 ±20.0) ml/min ],and there were no significant changes in other groups after low and high purine content diet.24 h urine protein in hyperuricemia group was higher than middle-aged group ( P＜0.05 ),and increased after high purine content diet with significant difference ( P＜0.05 ).These results suggest that high purine content diet and decreased by renal uric acid clearance mainly contribute to hyperuricemia in old people.

Objective:To evaluate the safety and feasibility of the in-situ needle fenestration combined with the in vitro physician modified fenestration technique to reconstruct supra-aortic branches during thoracic endovascular aortic repair (TEVAR) for aortic arch lesions requiring landing at Z0 and Z1.Methods:From Nov 2017 to Dec 2019, eighteen patients who underwent both the in-situ needle fenestration and the in vitro physician modified fenestration techniques to extend the proximal landing zone to Z0 and Z1 during TEVAR were included in our study.Results:Sixteen patients underwent in vitro physician modified fenestration ,two patients underwent in vitro physician modified fenestration to reconstruct both the left common carotid artery and the innominate artery. All eighteen patients received in-situ needle fenestration to preserve the left subclavian artery. Supra aortic branches were preserved in all patients (38/38, 100%). There was no Type Ⅰ endoleak. Type Ⅱ endoleak was found in four paitnets (4/18). Type Ⅲ endoleak occurred in one patient (1/18). Type Ⅳ endoleak in four patients (4/18). Type Ⅲ endoleak needed open aortic arch repair 6 months later. The median follow-up time was 12 months. One (1/18) died in 12 months and the other patients were doing well.Conclusions:The joint application of the in-situ needle fenestration and the in vitro physician modified fenestration to reconstruct supra-aortic branches during TEVAR for aortic arch pathologies requiring landing at Z0 and Z1 was satisfactory.

Objective To explore the predictive value of brain lobe location of stroke lesion to development of long-term post-stroke depression(PSD)in the first-episode ischemic stroke patients for providing evidence for early intervention.Methods In the prospective study,158 patients aged 60 and over with first-episode ischemic stroke were continuously admitted into Department of Neurology of Shangqiu First People's Hospital from January 2013 to July 2013.The 2 to 3 years follow-up after stroke episode was performed in 126 cases for inquiring into correlation between brain lobe location of stroke lesion and development of PSD.The diagnosis of depression was in accordance with Mental Disorders Diagnostic and Statistical Manual 4(DSM-Ⅳ)standard,and divided into groups of stroke with depression(n=52)and stroke without depression(n=74).The degree of depression was evaluated by 17-item Hamilton Rating Scale for Depression(HAMD17).The location,number and volume of stroke lesions were determined by head MRI.The relationship between PSD and pathogenetic loci was analyzed by unconditional Logistic regression analysis.A difference in hemisphere commensalism.Results The morbidity of PSD was 41.3%(52/126),with 21.4%(27/126),12.7%(16/126),7.1%(9/126)in mild,moderate and severe PSD respectively.The frontal lobe(OR=2.824,95%CI=1.189-6.706)and the temporal lobe(OR=3.579,95%CI=1.233-10.393)cerebral infarction were correlated with the occurrence of PSD.The long-term PSD severity was more in frontal lobe than in temporal lobe(χ2=6.399,P<0.05).The average volume of cerebral infarction was larger in PSD group than in non-PSD group(t=3.271,P<0.05),and the average number of cerebral infarction loci was more in PSD group than in non-PSD group(t=3.176,P<0.05).The more severe the degree of depression according to HAMD17,the larger the average volume of cerebral infarction(F=6.280,P<0.05)and the more the average number of lesions(F=6.132,P<0.05).Conclusions The development of long-term PSD in the first-episode elderly patients is affected by the invasion site.The frontal lobe and temporal lobe infarction are independent risk factors for long-term PSD in patients with ischemic stroke,and the PSD was more severe in frontal lobe infarction than in temporal lobe infarction.

Objective To detect the characteristics of benign infantile seizures.Methods Fifty seven cases of benign infantile seizures were analyzed.Results All patients had a normal development before and after the onset of the seizures.The age of onset was from 1.5-30 months.The main manifestations included tonic clonic seizure,staring and motion arrest,64.9 % occurred in clusters.A family history of epilepsy or febrile seizures was present in 6 cases.Interictel electroen cephalograms were normal.The seizures were easily ceased after taking phenobarbital,carbamazepine or valproate.Antiepileptic drugs(AEDs)were discontinued in 51 patients.The mean ages of seizure stopping were 12.8 months and mean seizure′s durations were 4.1 months.Conclusion The benign infantile seizures can be easily controlled with a single AEDs for short time with favorable prognosis.

Objective To investigate the effects of maternal long-term exposure to low-dose trichlorfon on the serum paraoxonase (PON) activity of pregnant mice and development of embryos. Methods Female ICR mice (n=120) were randomly divided into control group and trichlorfon groups of different doses,and were managed by intragastric injection with trichlorfon of 0,2,10 and 50mg/kg,respectively. All the mice were managed once a day for a consecutive of 27 days,and were subjected to mating. The pregnant mice were continued to be managed with trichlorfon for 3 days,and were sacrificed on day 3 of gestation. The serum PON and acetylcholinesterase (AchE) activities were detected,and the development of embryos was evaluated. Results The serum PON activity of 2,10 and 50mg/kg trichlorfon group were (14.15?1.22),(12.78?1.80) and (10.45?1.95)IU/mL,respectively,and that of 50mg/kg trichlorfon group was significantly lower than that of control group [(13.37?2.31)IU/mL] (P0.05),while the the percentage of abnormal embryos of 50mg/kg trichlorfon group had an increased tendency. Conclusion Long-term exposure to low-dose trichlorfon can inhibit serum PON and AchE activity in pregnant mice without obvious effect on the development of embryos.

Background It has been determined that dipeptidyl peptidase Ⅲ (DPPⅢ) plays an important role in the metabolism and modification of proteins and DPPⅢ of human has highly homologous to rat.Researches have shown that DPPⅢ is associated with the formation of cataract.However,few relevant studies have been reported.ObjectiveThe present study is to find out the relationship between the expression of DPPⅢ in rat lenses and age-related cataract.Methods Lenses were obtained from general Wistar rats of ages 3,6,9,or 12 weeks old (10 lenses each ) and homogenized with different concentrations of standard bovine serum.The proteins were resolved using SDS-PAGE gel electrophoresis.Peak concentration and total concentration of DPPⅢ protein in lenses from rats of different ages were detected by Western blot.Enzyme activity of DPPⅢ was determined by monitoring the amount of dipeptides removed from a special substrate (Arg-Arg-4mb NA) by measuring the absorbance with UV-2500PC at 525 nm.The relationship between the enzyme activity of DPPⅢ in lenses and age of rats was evaluated using regression analysis.Results DPPⅢ was detected at a molecular weight of 82000 Da.The peak concentration and total concentration of DPPⅢ in normal rat lenses increased with the growth of age.The total protease activity of DPPⅢ in the lenses of rats was correlated with the ages of the rats (r=0.99,P＜0.05).Conclusion DPPⅢ may be involved in the alteration of crystallin during the development of lenses,and it may play an important role in the formation and aggravation of age-related cataract.
