Objective To analyze regularities in selection of analogous points for acupuncture and moxibustion treatment of restless legs syndrome in modern Chinese literature. Three large Chinese databases, China National Knowledge Infrastructure (CNKI), Wan Fang database (Wanfang) and VIP Database (VIP), were searched by computer to retrieve literature on acupuncture and moxibustion treatment of restless legs syndrome. A database of acupuncture and moxibustion prescriptions was set up. The characteristics of and regularities in selection of analogous points for acupuncture and moxibustion treatment of restless legs syndrome were analyzed by use of data mining techniques. Results A total of 107 related articles were included, involving 105 selected acupoints. The main analogous points for modern acupuncture and moxibustion treatment of restless legs syndrome are Zusanli, Sanyinjiao, Chengshan and Yanglingquan. The main meridians that the analogous points belong to are the Bladder Meridian of Foot-Taiyang, the Gallbladder Meridian of Foot-Shaoyang and the Spleen Meridian of Foot-Taiyin. Most of these acupoints are distributed on the lower limb and the lumbodorsal region. The most frequently used specific points that the analogous points belong to are Five Shu points and lower He-Sea point. Association rule analysis shows that the points that are most highly correlated are Yanglingquan and Zusanli. Attention is paid to acupoint selection based on syndrome differentiation and compatible application of local acupoints.Conclusions Selection of analogous points that have the same or similar indications for modern acupuncture and moxibustion treatment of restless legs syndrome makes acupoint combinations produce a synergistic effect and can improve the clinical therapeutic effect.

BACKGROUND: The injury of peripheral nerve may cause electroneurographic changes. However, what is the correlation between electroneurographic changes and the extent of nerve injury?OBJECTIVE: To probe into the changes of evoked electroneurography in early stage after nerve injury for clinical application and reference.DESIGN: Paired t-test in three groups of samples.SETTING: Department of Traumatic Orthopaedics People' s Hospital of Beijing University.MATERIALS:The trial was conducted in the Animal Center of the People's Hospital of Beijing University from August 2003 to December 2003. The subjects were 8 adult New Zealand rabbits of SPF grade(weighing 1.5 kg) and either gender from the Animal Center of Medical College of Beijing University.METHODS:The model of nerve injury was made in the 16 tibial nerves of the 8 rabbits, in which one third or two thirds of each nerve was ligated at the same transverse part. The samples were thus divided into three groups: non-injury (normal) group, 1/3 nerve injury group and 2/3 nerve injury group.MAIN OUTCOME MEASURES: The indices of evoked electroneurography, i. e. motor nerve condution velocity, negative M wave amplitude, negative M wave area, maximal M wave amplitude and maximal M wave area were measured in the three groups. The correlation between the extent of nerve injury and the 5 indices was analyzed.RESULTS: All the 5 indices of the 3 groups were significantly different( P＜ 0.05). The mean values of the 5 indices were 1.00 ±0.0,0.97 ±0.18,1.01 ±0.22;0.98 ±0.16 and 0.98 ±0.19 in normal group, 0.76 ±0.12,0.41 ± 0.24, 0.47 ± 0.30, 0.48 ± 0.27 and 0.50 ± 0.29 in 1/3 nerve injury group, and 0. 62±0. 10, 0. 11 ±0. 11, 0. 11 ±0. 10, 0. 12 ±0. 14 and 0.13± 0. 12 in 2/3 nerve injury group. The coefficient of correlation between the 5 indices and the injury were 0. 902, 0. 938, 0. 936, 0. 907, and 0. 914, respectively.CONCLUSION: In the early stage after peripheral nerve injury, the electroneurographic indices negatively correlate with the extent of nerve injury. The negative M wave amplitude and area are relatively more closely correlated with the extent of injury.

Objective To evaluate the clinical efficacy of Achillon,a novel guide for Achilles tendon suture produced by Newdeal Ltd in France,in the mini-invasive surgical treatment of acute Achilles tendon rupture. Methods Between December 2010 and March 2011,7 patients(7 feet) with acute Achilles tendon rupture were treated in our department.They were 5 males (5 feet) and 2 females (2 feet),with an average age of 34.2 years (range,21 to 53 years).The interval between injury and operation ranged from 1 to 11 days(3.8 days on average).A longitudinal incision approximately 2.0-3.5 cm in length was made around the ruptured Achilles tendon for minimally invasive repair after insertion of the Achillon.Postoperative rehabilitation was carried out. Results All the wounds healed at the first stage.All patients were followed up for 5 to 11 months, with an average of 7.2 months. All patients regained normal weight-bearing walking 3 months after operation without any re-rupture. According to the ankle-hindfoot scoring system of American Orthopaedic Foot and Ankle Society (AOFAS),they scored 93.2 points.By the visual analogue scale(VAS),they scored 1.2 points at the operation site. Conclusion The surgical treatment of acute Achilles tendon rupture with Achillon has advantages of mini-invasion,a low rate of incision problems and quick function recovery.

Objective To investigate the role of peroxisome proliferator-activated receptor γ (PPARγ) in hematogenous spread of hepatocellular carcinoma after hepatic ischemia reperfusion in mice and its mechanism.Methods One hundred and sixty mice were randomly divided into 4 groups,sham,control,Rosiglitazone(R group) and Rosiglitazone + GW9662 (R + GW).The mice models with hepatic ischemia reperfusion combined with portal vein metastasis of hepatocellular carcinoma were well established.Serum ALT level,expressions of MMP-9,NF-κB and PPARγ,hepatic replacement area (HRA) and survival of mice were compared.Results (1) The median survival in sham group was 16.3 d,R group 12.1 d,control group 9.6 d,R + GW group 8.7 d.(2) Impact on portal venous metastasis:compared with left hepatic lobe (ischemic hepatic lobe) of control group,the HRA was significantly decreased in the left hepatic lobe of sham group (29.1％ vs.13.2％,P ＜0.05).Tumor load was higher in control group than R group (29.1％ vs.13.0％,P ＜ 0.05).(3) Serum ALT level:after 2 h,8 h and 24 h hepatic ischemia reperfusion injury (HIRI),the ALT levels in control group [(1 134.2 ± 320.5) U/L],R group [(1 017.3 ± 365.9)U/L] and R + GW group [(1 344.0 ± 304.3) U/L] were all higher than sham group [(20.6 ± 7.8) U/L],P ＜0.05.With 8 and 24 h HIRI,ALT levels were highest in R + GW group [(4 101.7 ± 462.2) U/L,(3 730.8 ± 582.7) U/L],following by control group [(3 649.1 ± 440.1) U/L,(2 226.7 ± 442.7) U/L],andRgroup [(1691.9±398.6)U/L,(1 109.2±237.4)U/L],P＜0.05.(4) MMP-9 expression:after 8 h HIRI,MMP-9 expression level was predominantly elevated in control group than R group [(41.3 ± 10.7) vs.(4.7 ± 1.1),P ＜ 0.05].Similarly,MMP-9 expression was higher in R + GW group than both control and R groups [(166.9 ± 7.9) vs.(41.3 ± 10.7) and (4.7 ± 1.1),P ＜ 0.05].(5) Expressions of PPARγand NF-κB:in the control group,PPARγ expression emerged after 2 h HIRI,and reached the peak with 8 h HIRI,decreased significantly with 24 h HIRI.NF-κB expression elevated with time,and at the peak with 24 h HIRRI.In R + GW group,the PPARγ expression was similar to control group and high expression of NF-κB were detected at all three endpoints.In R group,marked expression of PPARγ was observed after 2 h HIRI,and reached to peak after 24 h HIRI.NF-κB showed weakly positive expression after 2 h HIRI.Conclusions Rosiglitazone could significantly reduce hematogenous spread of hepatocellular carcinoma after hepatic ischemia reperfusion in mice.This may be attributed to NF-κB expression inhibition by PPARγ up-regulation and decreased MMP-9 production after pretreatment with Rosiglitazone.

AIM: To explore the cytokines level and the discrepancy of reaction to dexamethasone (Dex) in ALI rats induced by hydrochloric acid (HCl) and lipopolysaccharide (LPS). METHODS: Ninety-six SD rats were divided into six groups at random (n=16 in each group): NS group, HCl group, LPS group, NS+Dex group, HCl+Dex group and LPS+Dex group. Every group was divided into two subgroups: the bronchoalveolar lavage (BAL) subgroup and no bronchoalveolar lavage (NBAL) subgroup. The total leukocytes, PMN%, macrophage%, lymphocyte%, total protein in BALF and the wet/dry of the lung weight were measured. The concentrations of TNF-?, IL-1?, IL-4 and IL-10 in serum and BALF in every group were compared. RESULTS: (1) In the groups of LPS and HCl, the total leukocytes, PMN numbers, the protein concentration in the BALF and W/D were higher than those in control group (P

ObjectiveTo study the correlation with Genes Coding forESBLs and ClassⅠIntegron in ESBLs-producing Escherichia coli from children.MethodsPCR was used for gene typing detection of 100 strains of ESBLs-producingEsche-richia colistrains. While detection of class I integrase gene in the 100 strains ESBLs-producingEscherichia coli and 100 strains of non-ESBLs producingEscherichia coli were separately performed by PCR. It provides the solid base not only to reveal the relationship between class I integron and drug resistance, but also the relationship between class I integron and ESBLs-producing. ResultsThe most frequently genotyping from ESBLs-producingEscherichia coli in children isCTX-M (84%), followed by TEM-1(63%). The predominant distribution of genotype in ESBL- producing strains isTEM-1 +CTX-M (45%), followed by CTX-M (34%). Class I integrase gene detected in ESBLs- producing and non- ESBLs producing strain were 100 cases (100%) and 25 cases (25%) separately, the difference was statistically signiifcant (P<0.05); drug resistance in class I integron positive strains were signiifcantly higher than in class I integron negative strains, especially in Ciprolfoxacin, Levolfoxacin, and Amino-glycoside (86.4%, 88%, and 80%).ConclusionsThe distribution of Class I integron in ESBLs-producingEscherichia coli is signiifcantly higher than that in non-ESBLs-producing strains, It is rational that Class I integron highly correlate with strong drug resistance in ESBLs-producing strains.

Objective To measure mitral annual displacement (MAD) by M-mode echocardiography in normal second and third trimester fetuses,and assess relationships between MAD and gestational age and routine echocardiographic parameters for evaluation of left ventricular function.Methods One hundred fifty-five normal fetuses from 19 to 38 weeks of gestation were recruited in the study.MVD and tricuspid annual displacement (TAD) were measured.Early diastolic inflow velocities (E) of the atrioventricular valves were assessed by pulsed-wave Doppler(PW),and early diastolic velocities (Em) of the mitral annular were estimated by pulsed-wave tissue Doppler imaging (TDI).The ratio of E/Em was calculated.Results In normal fetuses,the MAD was (7.05 ± 1.17) mm.There was significant positive correlation between the fetal MAD and advancing gestational age ( r =0.82,P ＜0.01 ),and between MAD and E,A,Em,Am or Sm ( r =0.25,0.24,0.32,0.29 and 0.40 respectively,P ＜0.01).There was no correlation between fetal MAD and E/A,E/Em,LVEF or LVFS.The left MAD was significantly lower than the right TAD ( P ＜0.01 ).Conclusions MAD of fetuses from 19 to 38 weeks of gestation can be quantitatively measured by Mmode echocardiogram.The measurement of MAD provides a reliable quantitative standard to estimate long axis ventricular function of fetuses,which may be clinically useful in prenatal detecting early cardiac failure.

Objective To explore the common causes and associated risk factors for unintentional injuries among inpatient children from Yuying Children's Hospital of Wenzhou Medical College during 2007～2008.Methods This retrospective study involved 2 672 children of 0～18 years of age treated for unintentional injuries in Yuying Children's Hospital of Wenzhou Medical Collge from 2007 to 2008.Statistical evluation included x2 analysis and computation of relative risk(RR)with a 95％ confidence interval(CI).Results The top five types of unintentional injury were falls from one level to another(e.g.from playground equipment,chair,bed,stationary vehicle,and so on.)or falls on same level(e.g.from slipping,tripping,stumbling,collision,and so on)(30.84％),traffic accident(25.15％),falls from height(e.g.from balcony,bridge,building,window,and so on)(11.56％),foreign body ingestion/inhalations(6.89％),open wounds including cut,lacerarion and puncture wound(6.51％).The types of unintentional injury were not uniform among different age groups(x2 =602.12,P ＜0.01).Boys had a higher incidence of injury than did girls with a ratio of 2.34∶ 1.Unintentional injury rates varied considerably by age(x2 =583.90,P ＜0.01).The most prevalent age group was 1～4 years old.The most common body part injuried was the extremity region(54.00％).20.40％ of cases had injuried to the neck and head,15.27％ had thorax and abdomen injuries,3.78％ had vertebral column injuries and 1.87％ had pelvis injuries.Significant differences existed in injuried body site among different age children(x2 =315.21,P ＜0.01).The discharge departments were traumatic department(42.07％),hand surgery and spinal department(22.16％),department of otorhinolaryngology(6.89％),orthopaedic department(6.32％),neurosurgical department(5.84％),and the other discharge departments included pediatric surgical department,chest surgery department,stomatology department,ophthalmic department,pediatric intensive care unit and pediatric internal department.The number and rate of unintentional injury were the highest in summer(July-September),accounting for 28.63％.The estimated days and cost of unintentional injuries were 1 1.72 d and 9 617.96 yuan RMB each child,respectively.Conclusion Injury prevention efforts should include consideration of the substantial differences in the leading causes of unintentional injuries,in regard to sex,age and type of injury.Unintentional injuries lead to a threat to health and well-being and waste a majory source of medical spending in China for children and youth 0 to 18 years age.Making efforts to prevent child injury and establishing a complete emergency medical system are very important.
