Objective To assess the significance and the relationship of BODE index score and inflammation factors in stable chronic obstructive pulmonary disease(COPD).Methods Sixty COPD patients in their stable condition were evaluated for BODE index score and the level of tumor necrosis factor-α(TNF-α),interleukin-8(IL-8) and C reactive protein (CRP) were determined.Results BODE index score in COPD patients was positively correlated with serum concentrations of TNF-α,IL-8 (r =0.455,P ＜ 0.01 ; r =0.303,P ＜0.05),but not with CRP (r =0.111,P =0.398).IL-8 and TNF-α were both significantly negatively correlated to body mass index(BMI),force exhale volume of the first second (FEV1) and 6 minute walking distance (6MWD) (r=-0.417,P ＜0.01;r=-0.538,P＜0.01;r =-0.419,P＜0.01 for IL-8;and r=-0.262,P＜0.05;r=-0.348,P＜0.01;r=-0.334,P＜0.01 for TNF-α).Conclusion The BODE index,as a simple multidimensional grading system for COPD,is closely related to system inflammation,which indicates that system inflammation may contribute to the systemic development of COPD.

Objective To provide evidences for rational use of antibiotics in treatment of hospital-acquired urinary tract infection.Methods The bacteria isolated from mid-stream urine samples were collected for susceptibility test(MIC)using international standard plate dilution method.According to breakpoints defined in CILS guidelines(2009),each strain of bacteria was determine for susceptibility to antimicrobial agents,and calculated for rates of resistance(R%),intermediate(I%)and susceptibility(R%)to compounds tested.Results 552 strains of bacteria were collected,including 432 strains(78.3%)of Gram-negative bacilli and 120(21.7%)of Gram-positive bacilli;Escherichia coli was one of the most common bacteria in the urinary tract infection(55.3 %),followed by Enterococcus(17.4%).The results of antibiotic susceptibility test in vitro showed that Enterobacteriaceae was 100% susceptible to imipenem;Gram-positive cocci were sensitive most to glycopeptide antibiotics.Conclusion Clinicians should pay attention to the species of pathogenic bacteria causing urinary tract infection and their susceptibility to clinically common used antibiotics for reasonable use of drugs.

Objective To investigate the prevalence of latent tuberculosis infection(LTBI),and to identify the risk factors in primary schoolchildren from Shanghai through the population-based field investigation combined with the tuberculosis infection enzyme-linked immunospot assay(T-SPOT.TB)assay.Methods The children in grade 4 and 5 were enrolled from four primary schools in Pudong new district and Yangpu district of Shanghai.Questionnaire interview was applied to investigate the soeiodemographic and clinical information related to LTBI.The T-SPOT.TB assay was used to detect LTBI in the enrolled subjects.Univaitate and multivariate analyses were used to identify the risk factors associated with LTBI among the primary schoolchildren.Results Totally 472 schoolchildren were enrolled in the present study,with 439(93.0%)being vaccinated with bacillus calmette-guerin (BCG) and ten (2.1%) having contact history with tuberculosis (TB) patients.Among the 472 eligible subjects,16(3.4%) children were T-SPOT.TB positive,who had no clinical symptoms andsigns relevant to TB and were defined as LTBI.The LTBI prevalence in BCG vaccinated and unvaccinated children were 2.7% and 12.1%,respectively (OR:6.972;95%CI:1.834-26.500);those in TB contacts and children without TB contact history were 30.0% and 2.8%, respectively (OR: 16. 38; 95% CI: 3. 692-72. 700). Conclusions The prevalence of LTBI among senior schoolchildren in Shanghai is 3.4%. BCG vaccination is protective for children from LTBI, while daily contacts with TB patients increases the risk of LTBI in schoolchildren.

?AlM: To evaluate the clinical efficacy of posterior continuous curvilinear capsulorhexis ( PCCC ) combined with anterior vitrectomy in preventing posterior capsule opacification of congenital cataract surgery.
?METHODS:Postoperative clinical follow-up data of 82 cases ( 87 eyes ) with congenital cataract treated in Eye Center of our hospital from January 2011 to August 2014 were retrospectively analyzed. The patients were divided into the surgical control group ( 38 cases, 40 eyes, recieved phacoemulsification + PCCC ) and the study group ( 44 cases, 47 eyes, accepted phacoemulsification+ PCCC + anterior vitrectomy). The incidence of central optic axis opaque and postoperative visual acuity distribution were recorded at 1a follow - up. lntraoperative and postoperative complications were observed.
?RESULTS:The rate of central optic axis opaque grade 0 in control group was 37. 5%, compared to 76. 6% in study groups. The opacity distribution ratio of grade 1,2,3 and 4 in study group were lower than that of control group, and the central optic axis opacity distribution ratio in study group was significantly better than that of control group (P<0. 05). The 19 eyes(47. 5%) of visual acuity testing ≤0. 5 in control group , was higher than the 7 eyes(14. 89%) of that in the study group, The 21 eyes (52. 5%) of visual acuity testing >0. 5 in control group was lower than the 40 eyes ( 85. 11%) of that in study group. The visual acuity between two groups has statistical significance difference after 1a follow-up ( P<0. 05 ) , and the visual acuity in study group was significantly better than that in the control group. The postoperative intraocular pressure at 1mo and 1a follow-up was lower than before operation in two groups ( P<0. 05), but there was no significant difference between two groups in intraocular pressure (P<0. 05).
?CONCLUSlON: Combination of phacoemulsification, PCCC and anterior vitrectomy presents reliable clinical effects on postoperative central optic axis opacity distribution ratio and visual acuity, and it should be adopted to prevent the occurrence of posterior capsule opacification.

According to birth weight, 130 neonates were divided into 3 groups: macrosomia (n=28), intrauterine growth restriction (IUGR) (n=31) and normal neonates (n=71). The serum levels of LH, FSH and T were measured by radioimmunoassay.Results 1.The levels of LH, FSH and T in umbilical vein blood were significantly higher in male neonates than those in females (P

Persicae Semen (PS), a traditional Chinese medicine, has been widely used for the syndrome of blood stasis in China since the Eastern Han Dynasty. In the present study, we developed an HPLC-UV fingerprint analysis method for the quality control of PS. The HPLC fingerprint was performed on Shimadzu Inertsil C18 column (4.6 mm x 250 mm, 5 microm) at 35 degrees C. The mobile phases were composed of acetonitrile and water using a gradient elution. The flow rate was 1.0 mL x min(-1), and the detection wavelength was set at 210 nm. The fingerprint method was validated according to the Guidelines for Traditional Chinese Medicine Injection Fingerprint, and applied to determine 41 batches representative herbs collected from Xinjiang of China. The chromatographic peaks were characterized by UPLC-Q-TOF-MS, and nine of them were identified by comparison with the literature and/or reference standards. In order to classify and assess the samples, hierarchical clustering analysis and partial least square discriminant analysis were performed based on the common chromatographic peaks, and the samples were geographically classified into two classes, with six chemical compounds as classification markers which were significantly different between the two classes (P < 0.05).

A novel serine protease with high purity was extracted from the venom of Agkistrodon hlays Pallas using monoclonal antibody affinity chromatography. This protease releases bradykinin and has arginine esterase activity without being activated. After purification, its hydrolytic activity exceeded 800 U/mg, far higher than its counterparts from mammalian sources. The purity of the kininogenase could exceed 95%. The acute toxicity and the long-term toxicity of this kallikrein was studied for its potential clinical application. The maximum tolerance dose in adult was 150,000 times greater than the maximum applied dose, and long-term administration at the dose 50 times of allowed clinical dose did not obviously after the animals' body weight, survival condition, liver function, renal function, or blood routines, suggesting the extremely low toxicity of the kallidrein.

Objective:To explore the amplitude of normal kidney motion in the 3D direction and its influencing factors under free-breathing condition.Methods:Clinical data of 28 patients with a KPS score≥80 who received 4D CT scan from March 2018 to March 2019 were collected. All patients were diagnosed with liver, pancreatic or lung tumors. The kidney was outlined and the geometric center and 3D coordinate values were recorded. The motion of bilateral kidneys in each direction and the 3D direction was calculated. The volume of kidney and surrounding organs, age, sex, height and body mass index (BMI) were recorded. Clinical data were statistically compared by t-test or nonparametric test. Results:The motion of the left and right kidneys in the the sup-inf (SI) direction were the largest up to (8.39±3.18) mm and (7.71±3.55) mm. The motion amplitudes of bilateral kidneys in male patients were significantly larger than those of the female counterparts in the left-right (LR), SI and 3D directions (all P<0.05). The motion amplitudes of bilateral kidneys in patients taller than 165 cm were significantly larger than those of their counterparts with a height of ≤165 cm (all P<0.05). Patients with a BMI≥25 kg/m 2 had significantly larger motion amplitudes of the left kidney in the LR and ant-post (AP) directions compared with those of normal weight counterparts (all P<0.05). The motion amplitude of the left kidney in the AP direction in patients with the left kidney volume of >180 cm 3 was significantly larger than that of patients with smaller left kidney volume ( P=0.014). Age was not significantly associated with kidney motion in each direction ( P>0.05). Conclusions:Kidney motion mainly occurs in the SI direction. The kidney motion amplitudes in male and taller patients are larger. Special attention should be paid to the use of breath motion control device to decrease the normal tissue damage.

Objective To study the regiments of continuous subcutaneous insulin infusion (CSII) in admitted type 2 diabetic patients, and to analyse the factors related to its effectiveness and insulin dosage. Methods A total of 1 276 type 2 diabetic patients were treated by CSII. The total efficacy of CSII was evaluted. The use of CSII was also analysed in the newly diagnosed patients, elderly patients, and patients with obese or infectious disease. Results The excellent control of blood glucose were achieved in (5.7±2.6)days in the dosage more early and quickly in the newly diagnosed group than that in the previously diagnosed group after the blood glucose levels achieved good control. The percentage of the patients reached the clinical relieve was also higher in the newly diagnosed group. The incidence of hypoglycemia was significantly higher in the elderly patients with lower basal insulin dosage at night. The bolus insulin dosage in the obese patients was higher than that in the non-obese patients. The patients with infectious disease usually have a higher basal insulin dosage than those without infectious disease. The days needed for achieving good control of blood glucose and the insulin dosage were related to infectious factors, the basal blood glucose and obesity. Conclusion The application of CSII among the patients is varied with different conditions. Blood glucose level, body mass index and infection factors are important to determine the initial insulin dosage.
