OBJECTIVE:To evaluate the clinical efficacy of Shuanghuanglian injection in the treatment of acute exacerbation of chronic obstructive pulmonary disease (AECOPD),and to observe its effects on the plasma levels of C-reactive protein (CRP),procalcitonin(PCT)and interleukin-6(IL-6). METHODS:A total of 100 AECOPD patients were randomly divided into observation group and control group,with 50 cases in each group. Control group received routine treatment,such as controlled oxygen therapy,intravenous dripping of moxifloxacin,bronchodilator for relieving asthma,mucolytic for eliminating phlegm,nu-tritional support. Observation group was additionally given Shuanghuanglian injection 1 ml/(kg·d)added into 5% Glucose injec-tion 250 ml intravenously,qd,on the basis of control group. Treatment course of 2 groups lasted for 10 d. Clinical efficacies of 2 groups were compared as well as the changes of serum levels of CRP,PCT and IL-6 before and after treatment and the occur-rence of ADR. RESULTS:After treatment,total effective rate of observation group was 96.0%,which was significantly higher than 82.0% of control group,with statistical significance(P<0.05). Before treatment,there was no statistical significance in se-rum levels of CRP,PCT and IL-6 between 2 groups (P>0.05). After treatment,serum levels of CRP,PCT and IL-6 were de-creased significantly in 2 groups,and those of observation group were significantly lower than those of control group,with statis-tical significance (P<0.05). There was no statistical significance in the incidence of ADR between 2 groups (P>0.05). CON-CLUSIONS:Shuanghuanglian injection can effectively improve serum inflammatory factors of AECOPD patients,and shows good clinical efficacy and safety.

Objective To investigate the prevalence features of helicobacter pylori (Hp) infection,anemia and iron deficiency in a po-pulation of Wuhan children with 2 to 6 years old,and the relationship between Hp infection and anemia,iron deficiency in the children.Methods Randomly taking 95 children who had taken tests in our hospital's check-up centre in 2008 as the study objects,2 kinds of exa-mination were employed to detect Hp infection.Serum levels of Hp-IgG were measured by enzyme linked immunosorbent assay (ELISA) methods to evaluate past infection.The 14C urea breath test (14C-UBT) was conducted to obtain information of the presence of current/active Hp infection.In the morning 3 mL fasting venous blood was collected to determine the serum levels of Hp-IgG antibodies and ferritin.Hemoglobin values were determined with a hemoglobinometer.Serum levels of C-reactive protein (CRP) were tested in order to determine whether the children had evidence of current inflammation or infection.In addition,demographic information such as age and gender of the children and information about their use of antibiotics within the prior month were recorded.All cases were divided into 2 groups including the Hp infection group and non-Hp infection group according to laboratory examinations,then the Logistic regression was applied to analyze the relationship between Hp infection and anemia,iron deficiency.The Kappa identity test was taked to compare the 2 measures.Results Of the 95 children,18.9% were anemic and 36.8% were iron deficient.Forty percent of the cohort had Hp-IgG antibodies,74.4% tested positive by the UBT.Presence of Hp-IgG emerged as a significant risk factor for anemia,iron deficiency in adjusted analysis controlling for demographic factors,current inflammation,and antibiotic use.Conclusions Findings from different measure of Hp may reflect different stages of infection,with UBT results reflecting an earlier stage of infection,and presence of Hp-IgG reflecting established Hp infection associated with anemia,iron deficiency.

Objective To discuss the effects of extract of Ginkgo BilobaLeaves(EGb) on expression of cytokine of renal interstitial fibrosis induced by transforming growth factor-?1 (TGF-?1) and extracellular matrix. Methods Cultured human kidney cells(HKC) were divided into three groups: control group,TGF-?1(8 ng/mL) group,and TGF-?1(8 ng/mL) added EGb(25,50,100,150 mg/L)group.After 72 h,expression of ?-SMA was detected by cell immunochemistry ABC,and collagen type I by Real-time PCR and Western blotting. Results Treated with TGF-?1(8 ng/mL) for 72 h,expression of ?-SMA and collagen type Ⅰ were up-regulated markedly compared with control group.Treated with EGb(25,50,100,150 mg/L)and TGF-?1(8 ng/mL)concomitantly for 72 h,expression of ?-SMA and collagen typeⅠ were down-regulated in dosage dependent manner compared with TGF-?1 group. Conclusion EGb can inhibit expression of ?-SMA and collagen type I in HKC induced by TGF-?1,and the possible mechanism might be related to the inhibition of EGb on renal tubular epithelial-myofibroblast transdifferentiation.

BACKGROUND: Ascariasis is one of the most common human parasitic infections worldwide. In some rare cases, ascariasis may cause serious consequences even sudden death. This study was undertaken to review the life-threatening complications of ascariasis in trauma patients reported in the literature. DATA SOURCES: Relevant articles about ascariasis and trauma were searched from Pubmed, Google scholar, Scirus, and Wanfang databases. RESULTS: Twenty-four patients with ascariasis were collected from 21 articles searched. Most of these patients were from tropical and subtropical countries. Of the 24 patients, 12 were children. Their major complications occurred in the airway passage and digestive tract. There were 3 fatal cases in these patients. Twelve of the 24 patients described in 10 articles were reported in the last 10 years. CONCLUSIONS: Early diagnosis and prompt intervention are essential to minimize the high morbidity and mortality of these serious complications in trauma patients. Physicians should be aware of the possibility of Ascaris infection in a trauma patient from endemic area of ascariasis. History of Ascaris infection and routine examination of feces forAscaris eggs may be helpful to make a correct diagnosis.

Objective To investigate the correlation of single nucleotide polymorphism of rs3731055 and rs2607775 of xeroderma pigmentosum group C (XPC) and smoking with genetic susceptibility to pancreatic cancer.Methods The clinical data of 214 patients with pancreatic cancer who were admitted to the First and Third Affiliated Hospitals of Xinjiang Medical University from January 2009 to June 2011 and 214 healthly individuals were retrospectively analyzed.The samples of venous blood of 214 patients with pancreatic cancer (case group) and 214 healthy individuals (control group) were analyzed by the Multiplex SNaPshot method.The count data were analyzed using the chi-square test.The association between the single nucleotide polymorphism of rs3731055 and rs2607775 with genetic susceptibility to pancreatic cancer was analyzed using the Logistic regression method.Results Four hundred and twenty-three samples of gene were successfully typed,including 210 in the case group and 213 in the control group.The frequency of G allele of XPC rs3731055 was 75.95％ (319/420) in the case group and 77.00％ (328/426) in the control group,with no significant difference between the 2 groups (x2 =0.12,P ＞ 0.05).The frequencies of genotypes GG,GA and AA were 58.57％ (123/210),34.76％ (73/210) and 6.67％ (14/210) in the case group,and 60.09％ (128/213),33.80％ (72/213) and 6.10％ (13/213) in the control group,with no significant difference between the 2 groups (x2=0.12,P ＞ 0.05).The frequency of C allele of XPC rs2607775 was 87.86％ (369/420) in the case group and 93.43％ (398/426) in the control group,with significant difference between the 2 groups (x2=7.75,P ＜ 0.05).The frequencies of genotypes CC,CG and GG were 77.62％ (163/210),20.48％ (43/210) and 1.90％ (4/210) in the case group,and 86.85％ (185/213),13.15％ (28/213) and 0(0/213) in the control group,with significant difference between the 2 groups (x2=8.54,P ＜ 0.05).Patients with rs2607775 GC genotype were associated with a significantly increased risk of pancreatic cancer compared with patients with rs2607775 CC genotype (adjusted OR =1.81,95％ CI:1.06-3.10,P ＜ 0.05).Patients with rs2607775 GC + GG genotype were associated with a significantly increased risk of pancreatic cancer compared with patients with rs2607775 CC (adjusted OR =1.98,95％ CI:1.16-3.36,P ＜ 0.05).The ratio of patients in the case group who smoked cigarettes ≥ 17 pack years was 25.24％ (53/210),which was significantly higher than 13.15 ％ (28/213) of the control group (x2 =11.37,P ＜ 0.05).The results of univariate analysis showed that patients who smoked cigarettes ≥ 17 pack years had higher risk of getting pancreatic cancer (adjusted OR =2.82,95％ CI:1.27-6.29,P ＜ 0.05).Patients who smoked cigarettes ≥ 17 pack years and with rs2607775 CC also had higher risk of getting pancreatic cancer (adjusted OR =2.87,95％ CI:1.18-6.99,P ＜0.05).No significant gene-environment interaction was observed between rs2607775 GC + GG and smoking ≥ 17 pack years (adjusted OR =3.65,95％ CI:0.67-20.03,P ＞ 0.05).Conclusions The polymorphisms of XPC rs2607775 may play a role in the onset of pancreatic cancer.Patients who smoke cigarettes ≥ 17 pack years are more easily to have pancreatic cancer.There is no interaction between smoking and XPC rs2607775 in influencing the progression of pancreatic cancer.

Objective To study the gait of children with spastic cerebral palsy (SCP) using plantar pressure measurement (PPM).Methods Twenty SCP children and 84 healthy children were recruited,and PPM was used to compare their gait cycle time,cadence,and standardized gait cycle parameters.Results Compared with the control group,gait cycle times in the SCP group were obviously prolonged,and their cadence was significantly slower.The side support phase and swing time in the SCP group were shorter,while the double support phase was longer than that of children in the control group.Conclusion PPM can be used to assess the gait of SCP children efficiently.

Baicalin extremely fine powder was made by using ball-mill and the effect of micronization on the micromeritics properties of baicalin was studied and analyzed. The microstructures of baicalin ordinary and extremely fine powder were compared by scanning electron microscope, differential scanning calorimeter and X-ray diffraction and the powder characteristic of them was investigated. The hygroscopicity was studied. The effect of micronization on the dissolution of baicalin was investigated. The results showed that the chemical constituents of baicalin were not changed after micronization with better compressibility. It was confirmed that micronization technology had a certain application value in promoting the insoluble component of baicalin absorption with higher dissolution.
