Objective Comparison the coincidence rate in the colloidal gold method and the passive agglu-tination method to detect mycoplasma pneumoniae (MP) infection, discuss the clinical value in rapid diagnosis of MP infection in the two methods. Methods Two-hundred patients with MP infection, including 100 cases in the the children group, and 100 cases in the adult group, were detected in MP-IgM antibody in serum with the colloidal gold method and the passive agglutination method. Results The positive rate of MP-IgM antibody with the passive agglutination method were slightly higher than that of the colloidal gold method in the children group (P > 0.05), While the positive rate of MP-IgM antibody with the passive agglutination method in the adult group were signifi-cantly higher than that of the colloidal gold method (P<0.05). When the antibody titer of MP-IgM antibody were 1:60, ≥1:320 in the children group, the coincidence rate of the positive results with the colloidal gold method and the passive agglutination method were 95.40%, 95.30%;When the antibody titer of MP-IgM antibody were 1:80, 1:160,≥1:320 in the adult group, the coincidence rate of the positive results with the colloidal gold method and the passive agglutination method were 0, 61.90%, 63.80%. Conclusions In the pediatric MP infection, for the high an-tibody titer of MP-IgM antibody, the positive coincidence rate with the colloidal gold method can reach clinical diag-nostic requirements. Clinical physicians according to the age and disease process of patients choose the appropriate method in order to realize the simple, rapid and accurate diagnosis of mycoplasma pneumoniae infection.

AIM:To investigate whether the protective effect of adiponectin on glucose and lipid metabolism is achieved through down-regulating major histocompatibility complex classⅡ( MHCⅡ) in the adipose tissue.METHODS:Adiponectin knockout ( KO) mice and C57BL/6 ( WT) mice were fed with high-fat diet and standard diet for 24 weeks, re-spectively.The body weight, fasting blood glucose (FBG), fasting insulin (FINS), homeostasis model assessment of insu-lin resistance (HOMA-IR), triglyceride (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol ( HDL-C) , hepatic histology, and classⅡtrans-activator ( CIITA) , histocompatibility 2 class II antigen E beta (H2-Eb1) and cluster of differentiation 74 (CD74) mRNA and MHC II protein levels in adipose tissue were measured at sacrifice.siRNA targeting MHC II and overexpression vector was used in 3T3-L1 cells to explore the effect of adiponectin on the protein level of MHCⅡ.RESULTS:The levels of body weight, FBG, FINS, HOMA-IR, TC, TG, LDL-C, hepatic steatosis, CIITA, H2-Eb1 and CD74 mRNA expression, and MHCⅡ protein expression in the KO mice were higher than those in the WT mice that fed with high-fat diet or standard diet.In 3T3-L1 cells, inhibition of adiponectin reversed MHC II protein level induced by specific siRNA.The expression of MHC II in adipocytes decreased after adiponectin was overexpressed.CONCLUSION: Adiponectin improves glucose and lipid metabolism through sup-pressing the expression of MHCⅡin the adipose tissue.

OBJECTIVE:To explore the clinical utilization of carbapenems in a hospital,analyze and evaluate its medication rationality. METHODS:All the 508 medical records of inpatients treated with carbapenems from Jul. 2012 to Jun. 2015 were retro-spectively investigated,the utilization and pathogenic examination of carbapenems were evaluated;by setting the carbapenems eval-uating standard,the medication rationality of carbapenems was evaluated and inappropriate cases were classified and analyzed statis-tically. RESULTS:The drug utilization indexed (DUI) of Imipenem and cilastatin sodium for injection and Meropenem for injec-tion were 0.80 and 1.32,respectively;the total rate of microbial inspection was 95.9%;according to the drug sensitive test result, the rate of drug selection was 62.8%;there were 54 cases(10.6%)of irrational use records,in which,irrational dosage(42.6%) and improper drug selection (31.4%) were the major problems. CONCLUSIONS:There are some inappropriate medication prob-lems in carbapenems utilization in the hospital. Developing the carbapenems utilization evaluation is helpful to discover typical medi-cation problems,which can provide reference for intervention and continuous improvement of rational drug use.

Objective To clarify the advantages and disadvantages of domestic precision radiotherapy equipment by comparing the clinical efficacies of domestic and imported precision radiotherapy equipments in the treatment of lymphoma. Methods We investigated the treatments of lymphoma in hospitals of different levels using domestic and imported medical linear accelerators and divided them into domestic and imported groups. The data of patients in the two groups were retrospectively analyzed, and the radiotherapy equipment brand, short-term efficacy, acute toxicity, dosimetric parameters of organs at risk and the costs of radiation therapy were compared between the two groups. Results A total of 101 cases receiving radiation therapy for lymphoma in 10 hospitals were collected, including 77 cases in the imported group and 24 cases in the domestic group. The overall response rates were high in both groups, being 88.3% (68/77) in the imported group and 87.5% (21/24) in the domestic group, with no significant difference (P=1.00). The incidences of hematological toxicity (>grade 2) were low in both groups, being 1.3% (1/77) vs 8.3% (2/24), with no significant difference (P=0.14). Subgroup analysis was performed on the dosimetric parameters of organs at risk and acute toxicity of the two groups for extranodal nasal type NK/T cell lymphoma, and there were no significant differences in the maximal dose (Dmax) of the lens, Dmaxof the optic nerve, or mean dose (Dmean) of the parotid gland between the two groups (all P>0.05). However, there was an increasing trend in the domestic group compared with the imported group for Dmeanof bilateral parotid gland (left: [2 306.53±1 119.66] cGy vs[ 1 279.44±1 026.95] cGy, P=0.16; right:[ 2 328.35±1 009.76] cGy vs[ 1 303.79±1 116.79] cGy, P=0.17). The incidence of grade 2 xerostomia in the domestic group was higher than that in the imported group, but the difference was not statistically significant (50.0%[ 2/4] vs 14.3%[ 1/7], P>0.05). The domestic group had significantly lower radiotherapy cost [( 26 743.9±8 061.2] yuan vs[ 42 428.7±14 744.7] yuan) and total hospitalization cost [( 36 702.1± 12 225.8] yuan vs[ 50 192.7±15 494.4] yuan) than the imported group (both P<0.01). Conclusion There is no significant difference in the short-term efficacy of lymphoma treatment between the domestic radiotherapy equipment and the imported radiotherapy equipment, while the treatment cost of the domestic radiotherapy equipment is relatively low. However, the dosimetric parameters of organs at risk of imported radiotherapy equipment is lower and the acute toxicity is less..

AIM:To explore the diagnosis and treatment methods of radioaction-induced optic neuritis ( RION) through the clinical dates of 17 patients.
METHODS: It was a retrospective case series study. From August 2008 to October 2013, 17 cases (24 eyes) of Rion clinical dates from Chinese PLA General Hospital were studied. The diagnosis methods including visual acuity, pupil, fundus, visual field, fundus fluorescein angiography (FFA), visual electrophysiological testing, and head MRI. To analysis the clinical date of patients with diagnosis of RION by statistical description.
RESULTS: The deterioration degree of vision: 13 eyes were classified as Ⅳ, 9 eyes as Ⅲ, 2 eyes as II. Ten eyes RAPD ( + ) , visual electrophysiology is extinguished. The retina of 5 eyes showed flame hemorrhages and cotton wool spots exudation. Optic nerve head edema in one eye. T1 - weighted MRI enhanced in 19 eyes which showed optic nerve of the intracranial and intratubal segments abnormal changed, optic chiasm and pituitary stalk signal abnormalities and enhancement of the optic nerve. Tortuous optic nerves and rough edges were observed in 5 eyes. Treatment effect: 4 eyes of visual acuity improved, 1 eye from blindness to light perception,1 eye from 0. 08 to 0. 2, 1 eye from 0. 4 to 0. 6,1 eye from 0. 04 to 0. 15, the rest of the cases did not see any improvement.
CONCLUSION: The unique clinical manifestation of RION can provide objective basis for clinical diagnosis in time, but there have not been proven any effective treatments.

ObjectiveTo evaluate the correlation between interleukin (IL)6 and primary hepatocellular carcinoma (HCC). MethodsCase-control studies that included quantitative data on plasma or serum IL-6 levels of patients with HCC were identified from PubMed, ISI Web of Knowledge, CBM, and CNKI. A meta-analysis was performed to quantitatively and comprehensively analyze data. ResultsTwenty-five studies were included and the meta-analysis was conducted separately for 3 groups: HCC vs controls, HCC vs liver cirrhosis, and HCC vs hepatitis. The serum IL-6 levels of patients with HCC were significantly higher than those of healthy controls (25 studies, standardized mean difference (SMD) 5.02, 95% CI: 4.13-5.91, Z=11.05, P＜0.000 1), patients with liver cirrhosis (15 studies, SMD=236, 95% CI: 1.54-3.19, Z=5.60, P＜0.000 1), and patients with hepatitis (7 studies, SMD=2.63, 95% CI: 1.24-4.03, Z=369, P=0.000 2). ConclusionThe inflammatory mediator, IL-6, may play an important role in the development and progression of HCC.
