1.Immune relevant issues on Mycoplasma pneumoniae infection
Chinese Journal of Applied Clinical Pediatrics 2016;31(9):645-649
Mycoplasma pneumoniae(MP) is the smallest organism that dose not need a host cell for replication.It is one of the most common pathogens of community acquired pneumonia in children.In recent years,the incidence of pneumonia mycoplasma pneumonia increased year by year,and severe pneumonia mycoplasma pneumonia,refractory pneumonia mycoplasma pneumonia cases also increased.MP causes a variety of clinical presentations,in addition to respiratory infections,there are also many extrapulmonary manifestations.Immune response plays a very important part in pathogenesis of MP infection.This article focused on the immune aspects in pathogenesis and extends to some diagnosis and therapeutic implications.

Chinese Journal of Minimally Invasive Surgery 2015;(1):68-70
Objective To explore the feasibility of a novel technique of anvil placement in combined use of laparoscopic and thoracoscopic Ivor Lewis esophagectomy. Methods From June 2011 to October 2012, we performed a novel technique of minimally invasive Ivor Lewis esophagogastrectomy in 20 patients with midthoracic esophageal cancer.The anvil was placed to connection with the esophageal stump under thoracoscopic vision, and an apical pleural stomach esophagus anastomosis was performed by using normal stapling. Results The mean operation time lasted for 200 minutes (150-300 minutes) with a mean blood loss of 180 ml (150-250 ml) without blood transfusion.The mean number of lymph nodes resected was 18 (12-44).No additional incision was required. There were no complications at post-operation and no anastomic leakage.The patient’s hospital stay lasted a mean of 10 days (8-12 days) .Follow-up reviews were conducted for 6 months and no recurrence was found in all the 20 patients. Conclusion Laparoscopic and thoracoscopic Ivor Lewis esophagectomy with novel technique of anvil placement for the treatment of esophageal carcinoma ensures the feasibility and safety.

Objective To establish the equation of chest CR for the estimation of age, and evaluate the significance of forensic medicine. Methods 5 measurements were selected to carry on the independent samples, and the status were analyzed by SPSS 19.0. Results The 5 measurements and age were line-related(P<0.05); Three group regression models were formulated; In a separate test, a control sample of 30 chest CR that not involved with formulating the regression equation was correctly estimated with 73.3% to 86.7% accuracy within 3 years. Conclusion The method set up in this paper can be used to estimate the age of Chinese Han adults.

Objective To investigate the effects of aloperine (ALO) on a model of dextran sulphate sodium (DSS)-induced chronic colitis in C57BL/6 mice.Methods Repeated colitis was induced by administration of four cycles of 4% DSS.The severity of colitis was assessed on the basis of clinical signs,ratio of colon weight and colon length,and histological grading scores.Moreover,secretory immunoglobulin A (S-IgA) and plasma haptoglobin (HP) were analyzed by enzyme-linked immunosorbent assay,and the changes of mRNA expression of ICAM-1and MIF gene in colorectal tissue were detected by quantitative reverse transcriptase real-time polymerase chain reaction using SYBR Green Ⅰ.Results ALO administration significantly attenuated the colon damage,caused substantial reductions of the rise in HP,and maintained the level of cecum S-IgA.ALO inhibited the ICAM-1mRNA expression and had no effect on MIF mRNA expression.Conclusion The effect of ALO on DSS-induced chronic colitis in mice is investigated for the first time,which suggests that ALO could be an attractive therapeutic candidate in the treatment of inflammatory bowel disease.

Objective:To explore the effect of glycynhizinatis on serum IgE level of rat model and patients with asthma.Methods:Trie rats were divided into four groups randomly: normal control, asthmatic model, model treated with GL, model treated with DS. The rats were sensitized and challenged with ovalbumin to establish an asthmatic model. The established models were measured by breathing curves, pathological changes in pulmonary tissue slices and the level of serum IgE. Furthermore, serum IgE level of patients with asthma was also detected. Results: High amplitude of breathing curve and fast rhythm were showed in group of asthmatic model, there were more inflammatary cells infiltration in the tiny bronchial wall, hyperplasia of cup-shaped cells and thicker smooth muscle in the pulmonary tissue slices. Compared with normal control, the level of serum IgE in model group increased obviously. The rats treated with glycyrrhizinatis showed low amplitude of breathing curve, decreasing inflammatary cells infiltration in pulmonary tissue slices of tiny bronchial wall, no hyperplasia of cup-shaped cells, and decreased serum IgE level. There were no significant difference between the groups of GL and DS. At the same time, the serum IgE level in patients with asthma was observed. The results showed that the level of serum IgE was higher in patients with asthma than that in normal control (P

Methods:HPLC was performed on a DiamonsilTM C18 column (250 mm × 4. 6 mm, 5 μm), the mobile phase A was 0. 025 mol·L-1 phosphonic acid solution (adjusting pH to 3. 0 with triethylamine)-methanol- acetonitrile (80∶10∶10) and the phase B was 0. 025 mol·L-1 phosphonic acid solution (adjusting pH to 3. 0 with triethylamine)-methanol-acetonitrile (350∶325∶325) with gradient elution at a flow rate of 1. 1 ml·min-1 , the detection wavelength was 269 nm and 284 nm, the injection volume was 20μl, and the column temperature was 40℃. Results:Under the HPLC conditions, the samples had good stability and separation. The calibration curve was linear within the concentration range of 19. 80 ng·ml-1-19. 80 μg·ml-1(r=0. 999 9) for 5-hydroxymethylfur-fural with the detection limit of 0. 18ng, and the average recovery was 99. 68% with RSD of 0. 12% (n=9). Conclusion:The method is accurate, sensitive, specific and reproducible, and can be used in the determination of related substances in enoxacin gluconate in-jection.
