OBJECTIVE To investigate and elucidate the role of histamine on the regulation of tight junctions(TJs) gene expression of the airway epithelial cells. METHODS We cultured primary human bronchial epithelial cells from healthy and asthmatic individuals in the presence of histamine for 96 hours in air-liquid interface (ALI) culture system. The TJs expression on the level of mRNA and protein was determined by RT-qPCR and immunofluorescence (confocal microscopy), respectively. RESULTS A RT-qPCR analysis revealed that the mRNA expression of several TJs were up- or down-regulated by histamine. However, examination by confocal microscope revealed no detectable alterations in the morphology of the tight junctions after stimulating with histamine. CONCLUSION Our findings that histamine could regulate the mRNA expression of TJs of bronchial epithelial cells. That might contribute to the pathogenesis of chronic airway inflammatory diseases.

Objective To study the clinical and imaging features of neonatal acute osteomyelitis.Method From 2011 to 2016,the clinical feature,laboratory results,pathogen,imaging features,treatment and prognosis of neonates who were diagnosed with acute osteomyelitis in NICU of People's Hospital of Xinjiang Uygur Autonomous Region were retrospectively studied.Result A total of 13 cases were enrolled during the study period,5 males and 8 females,with onset age of 7 ～30 d.8 cases had different degrees of fever and 5 of them showed dyspnea;8 cases had elevated skin temperature and swelling at the affected area;7 cases presented with irritability;6 cases had anorexia;all cases had elevated white blood cell count.Blood culture were taken immediately after their admission,and culture from the pus were taken for some patients.5 cases had positive blood culture and Staphylococcus aureus was the main pathogen.6 cases had positive pus culture,and 4 cases showed gram positive (G +) bacteria and 2 cases gram negative (G-) bacteria.Humerus and tibia were the main foci of the infection.4 cases had X-ray examination within 7 days of onset showing soft tissue swelling and no sign of bone destruction.13 cases had X-ray examination at 7 to 14 days of disease.Among them only 1 case showed soft tissue swelling,and the rest 12 cases had different levels of bone destruction and periosteal reaction.2 cases had X-ray examination after 14 days of disease,showing stiffening ring,inflammatory changes and periosteal reaction.All patients were treated with broad-spectrum antibiotics after admission,and the affected limbs were immobilized.3 cases had further surgical treatment.11 patients recovered and were discharged,1 patient was treated at local hospital after diagnosis and 1 patient refused further treatment due to serious complications after 35 d of hospital stay and was lost on follow-up.Conclusion The clinical manifestation of neonatal osteomyelitis is atypical,the radiological and pathogen examination should be carried out once osteomyelitis is suspected.Appropriate antibiotics and timely surgery can prevent further damage and long-term sequela.

Objective To observe the role of mulberry flavone on the expression of insulin receptor substrate(IRS)in HepG2 cells with insulin resistance, and to explore the possible molecular mechanism that mulberry flavone improves insulin resistance. Methods HepG2 cells were cultured to establish insulin-resistance cell model in high concentration of insulin, and then incubated with mulberry flavone. Effect of mulberry flavone on the HepG2 cell model of glucose incorporation rate was observed. Western blot was used to observe the variety of IRS protein expression. Results Mulberry flavone increased the glucose incorporation rate of (33. 9 ± 1.0)higher than that of Conclusions Mulberry flavone can improve insulin resistance. Furthermore, IRS protein expression increasing is the possible molecular mechanism that mulberry flavone improves insulin resistance.

Near infrared spectroscopy ( NIRS) is capable of determining water contents in oils. However, too much moisture contents in the oils will scatter rather than absorb the NIRS. This may cause greater measurement error. For this reason, a nonionic surfactant (Span-80) was screened to make the water in the oils evenly dispersed into small droplets. The NIRS analysis was subsequently employed to build support vector regression ( SVR ) model of the water content. In this experiments, the upper limit of the water content determination was improved from the conventional 0. 1% to 1. 0% ( V/V) by the oil-water stabilization. Applying successive projection algorithm, 15 valid variables (2. 9% of the original ones) from 511 NIRS variables were selected. With the proposed SVR model, the measurement precision criteria for the validation dataset were root mean squares error percentage 2 . 93%, correlation coefficient 0 . 9944 , and relative percent derivation 9 . 4732%.

Objective To observe the clinical efficacy of acupuncture plus medication and kinesiotherapy in treating cerebral stroke.Method A total of 126 patients with cerebral stroke were randomized into a treatment group of 42 cases, control group 1 of 40 cases and control group 2 of 44 cases. The treatment group was intervened by acupuncture, Chinese medication plus kinesiotherapy, control group 1 by acupuncture alone and control group 2 by kinesiotherapy alone. Before the intervention and respectively after 2-week and 4-week treatment, the three groups were observed by adopting the modified Barthel Index (MBI) and Fugl-Meyer Assessment (FMA), as well as the Activities of Daily Living (ADL).Result After the treatment, the MBI score, FMA score and ADL grading were significantly changed in the three groups (P<0.01). After 4-week treatment, the MBI score in the treatment group was significantly different from that in control group 2 (P<0.05). After 4-week treatment, the FMA score and ADL grading in the treatment group were significantly different from those in both control group 1 and 2 (P<0.05).Conclusion Acupuncture plus medication and kinesiotherapy is an effective approach in treating cerebral stroke and it can improve the ADL.

Twenty kinds of amino acids are simplified into 3 types: hydrophobic amino acids (H), hydrophilic amino acids (P) and neutral amino acids (N). Each residue is reduced to a bead which locates in the position of the C?琢 atom. The off-lattice model is adopted and the relative entropy is used as a minimization function to predict the tertiary structure of a protein. A new contact intensity function is given to consist with protein design research based on the relative entropy. Testing on several real proteins from Protein Data Bank (PDB) shows the good results obtained with the model and method. The root mean square deviations (RMSD) of the predicted structures relative to the native structures range from 0.30 to 0.70 nm. A foundation for studying protein design using the HNP model and the relative entropy was made.

Objective To evaluate the cause of ischemia related to myocardial bridge (MB) by using SPECT/CT MPI and CTCA.Methods A total of 294 patients with chest pain,tightness or palpitation undergoing both CTCA and MPI were retrospectively enrolled in this study from March 2008 to March 2013.Among them,49 patients (26 males,23 females,age:32-85 (55.4± 16.6) years) had MB.Locations of MB and myocardial ischemia were recorded.Fused MPI/CTCA was analyzed.If there was no mural atherosclerotic plaque-related stenosis on CAG at the same location of coronary artery where ischemic myocardium was found,then MB was considered as the ischemic cause.Myocardial ischemia rates of different MB locations were compared by x2 test.Results Among 49 patients with MB,3 cases had MB in proximal segment of LAD,34 in mid LAD,4 in distal LAD,3 in septal branch,2 in distal LCX,1 in intermedius,and 2 in mid RCA.There were 41 cases with myocardial ischemia.Myocardial ischemia in 32 cases was caused by MB,including 23 caused by MB in mid LAD.The myocardial ischemia rates of the most common MB location (mid LAD,n =34) and other locations (n =15) were not significantly different (67.6％ (23/34) vs 60.0％ (9/15),x2 =0.27,P＞0.05).Conclusions MB is commonly found in the mid LAD.The myocardial ischemia rates caused by MB is not related the MB location.Hybrid MPI/CTCA could evaluate the sites of coronary MB and myocardial ischemia simultaneously and therefore may be useful to evaluate the relationship between MB and myocardial ischemia.

Objective:Primary gastric choriocarcinoma (PGC) is a rare tumor. This study aimed to analyze cases reported in Chi-nese and two cases in our hospital. This study was also conducted to investigate the clinical characteristics and treatment of PGC. Meth-ods:The Chinese Medical Current Contents and China Biology Medicine database was retrieved with the following terms:primary gas-tric choriocarcinoma, stomach choriocarcinoma, and ectopic choriocarcinoma. The clinical data in published literature were retrospec-tively analyzed. Two cases from our hospital were also retrospectively analyzed. Results:A total of 16 patients with PGC (14 case stud-ies and 2 cases from our hospital) were included in this study. The average age of the patients was 57.69 years (ranging from 42 years to 79 years). Among the 16 patients, 4 were females and 12 were males. The main clinical manifestation was abdominal discomfort (12/16). Laboratory and imaging tests were non-specific, but HCG-βin all of the patients increased (11/11). Organ or lymph node metasta-sis was found in 13 patients, including 6 cases in which two or more organs showed metastasis. These organs were primarily the liver, the stomach lymph nodes, the lungs, the brain, and the abdominal cavity. Pathological examination results showed that 12 of the 16 cas-es displayed ulcers with necrosis and hemorrhage. The four remaining cases manifested lesions. Lesions may occur in the stomach less-er curvature (5 cases), stomach sinus (6 cases), cardiac (2 cases), and gastric body (3 cases). The histological components of PGC co-ex-isted with other factors, such as adenocarcinoma (7 cases), adenocarcinoma and squamous (2 cases), adenocarcinoma and a signet ring cell (1 case), or pure choriocarcinoma (6 cases). Surgery combined with chemotherapy was the main treatment. A total of 14 patients un-derwent surgical operations. Among these patients seven underwent chemotherapy after surgery and one underwent chemotherapy. Among the 10 patients who were followed up, 8 died within six months after diagnosis. Conclusion:PGC is a rare stomach cancer with poor prognosis and primarily affects older men. No characteristic clinical manifestations were observed, but HCG-βas a specific serum tumor biomarker increased in all of the affected patients. Histological components co-existed with other stomach cancers. Surgical exci-sion combined with chemotherapy was the preferred treatment in early stages, and systemic chemotherapy was the recommended treat-ment in advanced stages.
