This study aims to investigate the relationship between odor and contents of the chemical compounds in Lonicera japonica, including chlorogenic acid, galuteolin and polyphenols. High performance liquid chromatography (HPLC) was applied to determine the contents of chlorogenic acid and galuteolin in L. japonica. The ponptent of polyphenols was determined by UV-Vis Spectrophotometry. Electronic nose was used to extract and measure the odor of L. japonica. Then SPSS 17.0 software was employed for data processing. There is a significant positive correlation between the comprehensive index value of aroma and the contents of chlorogenic acid and polyphenols. The regression equations have been established. However, the relationship between the comprehensive index value and the content of galuteolin is not obvious. This is proof that the odor of L. japonica has close connection with the chemical compounds. Therefore, this research offered a new method for initially determine or predict the content of the chemical composition in L. japonica,

Objective To investigate the characteristics of IL-22 in Helicobacter pylori (H.pylori)infection.Methods Thirty H.pyloripositive and fifteen H.pylori negative gastric biopsy specimens were enrolled,IL-22 mRNA expression was detected by real-time PCR and the protein level of IL-22 was determined by ELISA in gastric tissue.The H.pyloriand cell coculture system was established and IL-22 expression was measured by real-time PCR to investigate the main source of IL-22 in gastric tissue.The IL-22-producing T cell was examined by FCM in the gastric mucosa tissue.Results Gastric mucosal IL-22 mRNA and protein levels were significantly higher in H.pylori-positive patients than uninfected patients (P＜0.05).A H.pyloriand cell coculture system was established successfully and gastric epithelial cell and T cell were the main source of IL-22 in gastric tissue.IL-22 was produced by CD4+ and CD8+ T cells and these T cells were increased in H.pylori-infected gastric mucosa (P＜0.05).Conclusion IL-22 took part in H.pyloriinfection induced immune response and increased IL-22-producing T cells was the important feature of H.pyloriinfection.

Heat shock factor 1 (HSF1) is the key protein in regulating stress response. It can be activated under heat, oxidative or another stress conditions. Dominant-positive and dominant-negative HSF1 are two types of HSF1 mutants. Both of them gain the DNA binding activity in the absence of stress. In addition, dominant-positive HSF1 acquires transcriptional activity, which dominant-negative HSF1 does not acquire. In this paper, the progress of using these HSF1 mutants in the research of cancer, neurodegenerative disorders and cardiovascular diseases will be discussed.

OBJECTIVETo observe the effect of electro-acupuncture (EA) on clinical outcomes and the occurrence of ovarian hyperstimulation syndrome (OHSS) in in vitro fertilization and embryo transplantation.

METHODSTotally 109 patients who routinely received in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) at Reproductive Center were assigned to the control group (56 cases) and the EA group (53 cases) according to even and odd-numbered date. Patients in the control group received controlled ovarian hyperstimulation (COH) referring to GnRH-a long protocol. On the basis of COH, those in the EA group received EA from the day of Gn injection to the day of embryo transfer. Estradiol (E2), vascular endothelial growth factor (VEGF), interleukin-6 (IL-6), and angiotensin (AT) II were measured in all patients on the day of hCG injection, the day of ovum pick up (OPU), and the day of embryo transfer (ET), respectively. The oocyte retrieval rate, good quality embryo rate, clinical pregnancy rate, the abortion rate, and the occurrence of OHSS were compared between the two groups.

RESULTSCompared with the control group, serum E2 levels on the day of OPU and the day of ET were significantly lower in the EA group (P < 0.05). On the day of OPU levels of VEGF and IL-6 also significantly decreased (P < 0.05). Serum levels of VEGF and IL-6 reached the highest line on the day of hCG in the two groups, and then showed a decreasing trend. Compared with the control group at the same time point, serum levels of VEGF and IL-6 obviously decreased on on the day of OPU, hCG, and ET (P < 0.05). The occurrence of OHSS and the canceling rate of transplant cycle were significantly lower in the EA group than in the control group (P < 0.05).

CONCLUSIONSEA, as an adjunctive therapy, could reduce the occurrence of OHSS in IVF. Besides, it did not decrease good embryo rates and pregnancy rates in IVF-ET, which might be associated with lowering local vascular permeability of ovaries.

OBJECTIVETo retrospectively analyze 95 cases of traumatic carotid cavernous fistula treated by endovascular embolization.

METHODSFrom January 1994 to December 2008, 95 patients with traumatic carotid cavernous fistula were treated in our hospital. All patients received selective cerebral angiography through femoral artery catheterization. Accordingly, 89 cases were treated by detachable balloon embolization, 5 by platinum microcoils and 1 by covered-stent, respectively.

RESULTSIn the study, 61 cases achieved successful balloon embolization at the first time. Fifty-six cases had multiple balloons due to the big fistula. Nine cases received balloon embolization twice. But among the 5 patients treated with platinum microcoils, one developed slight brainstem ischemia. After operation the patient had hemiparesis and swallow difficulty, but gradually recovered 3 months later. No neurological deficits were observed in other cases. All the cases recovered. Eighty-five cases were followed up for 1-15 years and no recurrence was found.

CONCLUSIONSThe endovascular embolization for traumatic carotid cavernous fistula is minimally invasive, safe, effective and reliable. The detachable balloon embolization is the first choice in the treatment of TCCF.

OBJECTIVETo investigate the involvement of MAPK p38 pathway in treatment of chronic renal failure with Jianpi Qinghua Decoction in rats.

METHODSForty SPF SD rats were divided into sham group (n=10),model group (n=10), Jianpi Qinghua group (n=10) and losartan group (n=10). Rat chronic renal failure was induced by 5/6 nephrectomy (Platt method) in model, Jianpi Qinghua and losartan groups, and rats in sham group received sham operation. Jianpi Qinghua decoction (3.9 g 200 g(-1)) or losartan (3.3 g 200 g(-1)) daily were administrated by gavage in Jianpi Qinghua and losartan groups for 60 days, respectively, Rats in sham and model groups were orally administered with saline of the same volume. The serum levels of creatinine and urea nitrogen were measured by biochemical method, the expression of MAPK p38 was detected by Western Blot,and renal pathological changes were observed with hematoxylin-eosin staining.

RESULTSCompared to model group,serum creatinine levels after 60d in Jianpi Qinghua and losartan groups were decreased significantly (42.67 ± 5.98 or 40.90 ± 5.07 compared with 60.90 ± 9.54, both P<0.01), the expression of MAPK p38 was significantly down-regulated (0.555 ± 0.004 or 0.587 ± 0.045 compared with 0.930 ± 0.265,both P<0.01) and serum urea nitrogen was also decreased (8.56 ± 0.75 or 7.97 ± 0.86 compared with 8.62 ± 0.62,both P<0.05). The renal pathology in the model group presented glomerular mesangial proliferation,hyperplasia of glomenrulus mesangial cells and interstitial inflammation. Those pathological changes were attenuated significantly in Jianpi Qinghua and losartan groups.

CONCLUSIONJianpi Qinghua Decoctions can improve the renal function and renal pathological changes in a rat with chronic renal failure, which may be associated with down-regulation of MAPK p38 immune inflammatory pathways.

OBJECTIVEPrimary airway neoplasms are extremely rare in the pediatric age group. This paper reports 4 children with primary airway neoplasms to explore the clinical manifestations, safety and efficacy of bronchoscopic interventions.

METHODThe data of pathology, photographic documentation and imaging studies were analyzed.

RESULTOf the 4 reported lesions, 2 were characterized by low-grade (2 with mucoepidermoid carcinoma) and 2 by high grade malignant (spindle cell carcinoma and malignant lymphoma). Onset of clinical manifestations occurred at the ages of 7 months to 7 years. All of them were initially misdiagnosed as bronchitis, asthma or atelectasis. The lesions located in trachea in 2 patients, in left bronchus of 1 patient and in right middle bronchus of 1 case. Atelectases occurred in bilateral bronchus where the lesions obstructed almost the entire lumen at the time of diagnosis. The diagnosis of airway masses depends upon maintaining a high index of suspicion, complemented by imaging and timely diagnostic endoscopy. The lesions were completely removed in 3/4 patients except 1 died during bronchoscopic procedures.

CONCLUSIONThe children with malignant airway neoplasms were presented with cough and wheezing without specific manifestations. Bronchoscopic interventions were effective in the treatment of non-operative cases. General anesthesia is strongly recommended for interventional bronchoscopy.
