Objective To explore the clinical and radiological findings of skeletal desmoplastic fibromas.Methods Radiographs of six patients with desmoplastic fibromas proved by pathology were retrospectively reviewed.Results Two tumors arose in femur,two in tibia,one in radius and one in humur.In plain radiography,these lesions were always metaphyseal and expansile lytic with a reactive bony rim(n=6).They often had a trabeculated or honeycomb appearance into lesion and four tumors invaded adjacent soft tissue.Conclusion Desmoplastic fibromas of long bones are nearly always metaphyseal.Radiographs disclose a expansile lytic lesion with a sclerotic rim and a trabeculated apperance into it.And the "root hair"sign is fairly characteristic for this tumor.No calcification and periosteal reaction can be seen.

OBJECTIVE: To observe the therapeutic efficacy of compressed atomized inhalation of Tanreqing injection for herpangina.METHODS: A total of 137 children with herpangina were enrolled: 69 cases(trial group) received Tanreqing injection 0.5 mL?kg-1?d-1 plus 5 mL normal saline q.d by atomized inhalation for 5 consecutive days,and 68(control group) received penicilin G sodium and ribavirin by iv gtt.The curative efficacy of the two groups was followed.RESULTS: There were significant differences between the trial group and the control group in total effective rate and marked effective rate(85.51 % vs.95.65% for total effective rate and 27.94% vs.66.18% for marked effective rate,P

BACKGROUND:With the development of minimal y invasive technique, more and more forearm fracture, especial y in children, was treated by elastic stable intramedul ary nailing. Recently, elastic stable intramedul ary nailing was also used in elder children, even adults. In particular, this technique has obtained good curative effects for open fracture and unstable fracture. OBJECTIVE:To evaluate the clinical effectiveness and safety of elastic intramedul ary nail and plate fixation for double fracture of forearm using evidence-based medicine. METHODS:We retrieved PubMed, Embase, Cochrane Library, China Biology Medicine, VIP, China National Knowledge Infrastructure, WanFang, and other electronic databases. The quality of the included studies was assessed using Cochrane Systematic Review. The analysis was performed using RevMan 5.2 software. RESULTS AND CONCLUSION:A total of 7 randomized control ed trials involving 468 cases were included. The results of meta-analyses showed that compared with plate fixation group, effective rate was higher in the titanium elastic nail group (P<0.000 1), the time of fracture healing was shorter (P<0.000 01), and the hospitalization time was shorter (P<0.000 01). In the aspect of adverse reactions, incidence of refracture (P=0.03) and breakage of internal fixation (P=0.03) was significantly lower. These indicated that compared with plate fixation, titanium elastic nail can improve the total effective rate, shorten the time of fracture healing on X-ray and the hospitalization time, at the same time, can effectively reduce the complications of refracture and breakage of internal fixation.

Objective To determine the roles of thymic stromal lymphopoietin receptor (TSLPR) and its antibody in airway inflammatory response in asthmatic mice, and to promote maturation and activation of dendritic cells (DCs) in mouse airway. Methods BALB/c mice were randomly divided into group A, B and C. The mice in group B and C were intraperitoneally injected with OVA for allergization while the mice in group A were intraperitoneally injected with PBS as the normal control. The mice in group B and C were treated by inhalation of non-specific IgG and TSLPR IgG respectively, before provocation of asthma using OVA. The bronchoalveolar lavage fluid (BALF) of the mice in different groups were collected for cell differential counts and quantitative detection of IL-4, IL-5, IFN-γand IL-10 levels by ELISA. Moreover, the pulmonary tissue specimens of the mice were collected for pathological examination, and the numbers and phenotypes of DCs from the local lymph nodes and pulmonary tissue were determined by flow cytometry. Results The levels of all the tested cytokines in the BALF from mice in group B and C were remarkably higher compared to those from mice in group A (P<0.01). However, both the IL-4 and IL-5 levels in the BALF from group C mice that pre-blocked with TSLPR IgG were lower than those from group B (P<0.05, P<0.01), whereas both the IFN-γ and IL-10 levels in the BALF from group C mice were higher than those from group B (P<0.05, P<0.01). Furthermore, the numbers of total cells, eosinophils and lymphocytes in the BALF from group C mice were also lower than those from group B (P<0.01). A large number of inflammatory cell infiltration around the bronchus, beaker cell proliferation and mucous secretion reinforcement could be found in the samples from group B mice, while slight inflammatory cell infiltration and beaker cell proliferation in the samples from group C mice. The numbers of DCs in mediastinal lymph node and the levels of I-Ad, CD40, CD80 and CD86 expression of pulmonary DCs from group B mice were higher than those from group C mice (P<0.05). Conclusion TSLP/TSLPR have an effect on promoting asthma, which is closely relative to its regulation of DCs activation. And the interference of TSLPR antibody can decrease the effect of TSLP/TSLPR which indicating a potential of the antibody as a novel anti-asthma drug.

Ebola virus (EBOV) and Marburg virus (MARV) are causative agents of severe hemorrhagic fever with high mortality rates in humans and non-human primates and there is currently no licensed vaccine or therapeutics.To date,there is no specific laboratory diagnostic test in China,while there is a national need to provide differential diagnosis during outbreaks and for instituting acceptable quarantine procedures.In this study,the TaqMan RT-PCR assays targeting the nucleoprotein genes of the Zaire Ebolavirus (ZEBOV) and MARV were developed and their sensitivities and specificities were investigated.Our results indicated that the assays were able to make reliable diagnosis over a wide range of virus copies from 103 to 109,corresponding to the threshold of a standard RNA transcript.The results showed that there were about 1010 RNA copies per milliliter of virus culture supernatant,equivalent to 10,000 RNA molecules per infectious virion,suggesting the presence of many non-infectious particles.These data indicated that the TaqMan RT-PCR assays developed in this study will be suitable for future surveillance and specific diagnosis of ZEBOV and MARV in China.

Objective To analyze the difference of the venous port access (VPA) and peripherally inserted central catheter (PICC) in cancer chemotherapy.Methods All eligible studies on VPA and PICC were searched in the databases of PubMed,China National Knowledge Internet (CNKI),Chinese Biomedical Database (CBM),WANFANG Database and VIP Database.Literatures screening,quality evaluation and data extraction were conducted according to Cochrane Handbook;Meta-analysis was calculated by using RevMan 5.2.Results Twenty-nine studies with a total of 4 449 cases of patients were included in this Meta-analysis,with 1 912 cases in experimental group which adopted VPA and 2 537 cases in controlled group which adopted PICC.Experimental group had advantages in the average catheter retention time (SMD=3.36,95％CI 2.51-4.21) and quality of life (RR=1.61,95％CI 1.15-2.24) compared with controlled group.The overall complication rate (RR=0.26,95％CI 0.20-0.34,P＜0.01),phlebitis incidence (RR=0.08,95％CI 0.04-0.16,P＜0.01),catheter infection incidence (RR=0.32,95％CI 0.23-0.44,P＜0.01),catheter obstruction incidence (RR=0.32,95％CI 0.22-0.48,P＜0.01),catheter dystopy incidence (RR=0.18,95％CI 0.09-0.37,P＜0.01) in experimental group were remarkably lower than that in controlled group.However,no significant difference was found between the two groups in the incidence of the puncture success rate for the first time,errhysis or hematoncus,thrombus and catheter leakage (P ＞0.05).Conclusions Compared with PICC,VPA had advantages in a long retention time,fewer complications and few influence on quality of life.Therefore,VPA should be widely used in cancer chemotherapy.

Objective To analyze the change in the concentration of IL-17 and IL-10 inflammatory factors among the deadaptation personnel who returned from the plateau.Methods A total 21 healthy males were investigated who averaged 25 years in age, lived permanently in the plains (200 m), and once stayed to the plateau (Lasha) for 6 months.Their venous blood was collected at three time points:the day before ascending to the plateau(control), the second day after return to the plains(d2) and the 30th day(d30), respectively.Their serum was seperated from the whole blood and the level of IL-17A and IL-10 was detected by ELISA method.Results The concentration of IL-17A and the IL-17A/IL-10 ratio were significant increased at d2 and d30, respectively, compared with control (P<0.05).Compared with d2, IL-17A and the IL-17A/IL-10 ratio were decreased obviously at d30(P <0.05).The level of IL-10 at d2 and d30 was significantly reduced compared with control ( P <0.05), but increased at d30 compared with d2.Correlative analysis showed that there was a negative correlation in the levels of IL-10 and IL-17A between control, d2 and d30, respectively (r1=0.948, P<0.05;r2=0.969, P<0.05;r3=0.972, P<0.05).A significant negative correlation was observed in the alteration levels of IL-10 and IL-17A between the three groups(r4=-0.793, P<0.05; r5=-0.756, P<0.05). Conclusion The concentration of inflammatory factors among the plateau deadaptation patients is imbalanced, but it is gradually reduced with time.The mechanism is still not clear.

Objective To explore effects of different urostomy education paths in patients undergoing cystectomy with creation of a urostomy.Methods 42 cases of patients after radical cystectomy with creation of a urostomy were randomly divided into the control group and the observation group. The control group received the original version of urostomy education path, while observation group received modified version of urostomy education path. Knowledge of urostomy, stoma bag replacing skills, and length of hospital stay were compared between the two groups. Results Patients in the observation group who received modified version of urostomy education path showed better knowledge of urostomy and skills of replaceing stomy bag, as well as shorter hospital stay (P<0.05).Conclusions Our modified version of urostomy education path results in improved self-care ability among patients and their family members. It suggests the urostomy education needs constant innovation and enhancement on the basis of practice.

OBJECTIVETo investigate the effect of apigenin on the protein expression levels of peroxisome proliferator-activated receptors (PPARs) in liver tissues of rats with nonalcoholic steatohepatitis (NASH).

METHODSThe NASH rat model was established by feeding of a high-fat diet. Unmodeled rats served as the normal controls. The modeled rats were divided into a model control group, Essentiale treatment grouP(300 mg/kg/day),and three apigenin treatment groups for low-dose (15 mg/kg/day), moderate-dose (30 mg/kg/day) and high-dose (60 mg/kg/day). After 13 weeks of treatment,changes in insulin sensitivity from pre-treatment baseline were assessed by measuring the alanine aminotransferase (ALT), aspartate aminotransferase (AST),total cholesterol (TC),triglycerides (TG),low-density and high-density lipoprotein cholesterol (LDL-C and HDL-C),fasting blood glucose (FBG) and fasting insulin (FINS).The liver index and HOMA-IR were also calculated.Protein and gene expression of PPARα and PPARgamma in liver tissue were assessed by immunohistochemistry and RT-PCR.Statistical analysis was performed by the LSD test and Games-Howell test.

RESULTSThe apigenin-treated groups showed a significantly greater change in insulin sensitivity than the untreated model group,with the most significant change occurring in the high-dose grouP(P less than 0.05).Compared with the untreated model group,the apigenin-treated groups showed lower levels of ALT (95.4+/-7.3),AST (183.7+/-14.3),TC (1.61+/-0.25),TG (1.23+/-0.21),LDL-C (1.86+/-0.14),FBG (5.29+/-1.45) and FINS (0.76+/-0.86),but a higher level of HDL-C (1.04+/-0.17); again,the high-dose group showed the greatest change (all P less than 0.05).Compared to the untreated model group,the apigenin-treated groups showed significantly lower liver index (3.75+/-0.25 vs.2.90+/-0.17) and HOMA-IR (1.34+/-0.06 vs.0.18+/-0.04),with the high-dose group showing the greatest change (both P less than 0.05). Compared to the untreated model group,the apigenin-treated groups showed higher levels of protein and mRNA of PPARα (18.27+/-4.05 and 0.63+/-0.02,respectively) and PPARgamma(8.48+/-5.05 and 0.39+/-0.02),with the high-dose group showing the greatest change (all P < 0.05).

CONCLUSIONApigenin can improve glucose tolerance,lipid metabolism and insulin resistance while decreasing blood levels of TC,TG,LDL-C,FBG,FINS and HOMA-IR,and increasing HDL-C in NASH,as shown in a high-fat diet induced rat model, and may have therapeutic potential.
