Objective Mycoplasma pneumoniae is one of the main pathogens of community-acquired pneumonia in children and teenagers , which may cause mycoplasma pneumoniae pneumonia ( MPP) .Atelectasis is one of the most common manifestations of MPP.The aim of the article was to evaluate the diagnostic and therapeutic value of fiberoptic bronchoscopy ( FB) in children with MPP associated with atelectasis . Methods Retrospective analysis were made on clinical data and FB records of 99 cases of hospitalized children with MPP associated with atelectasis from August 2010 to December 2012 . Results The positive rate of MP-DNA was 92.9%(92/99) in bronchoalveolar lavage fluid (BALF), and the positive rate of MP-Ab-IgM in serum was 68.7%(68/99).All pa-tients showed obviously bronchial mucosa congestive edema during FB examination .The results are as follows:bronchial phlegm bloc-king in 31 cases (31.3%), lumen inflammatory stenosis in 22 cases (22.2%),mucosal ulcer change in 7 cases(7.1%) and mucous nodular change in 3 cases (3.0%).4 weeks after being treated with bronchoalveolar lavage (BAL), only 3 cases remained in atelec-tasis, the partial and complete re-expansion rate reaching 96.5%(82 of 85). Conclusion The positive rate of BALF MP-DNA de-tection technology for the diagnosis of MP infection is higher than that of serum MP-Ab-IgM examination .Early interventional therapy by FB can shorten the course of disease and promote the lung re-expansion in children with MPP associated with atelectasis .

Objective To study the effects of benzyl propionate nandrolone (BPN ) on the nicotinamide phosphoribosyl transferase (Nampt), insulin receptor substeate-2 (IRS-2 )and pancreatic duodenal homeobox-1 (PDX-1)expressions, cell cycle changes as well as insulin secretion in pancreatic islet cell NIT-1 lines, and to explore the influence of BPN in the Nampte xpression in NIT-1 cells and insulin signaling molecules in high glucose oxidation stress.Methods The NIT-1 cells were cultured with different concentrations (5.6,11.1,16.7,and 27.6 mmol·L-1)of glucose,then they were treated with 10 mg·L-1 BPN for 48 h with no BPN treatment as corresponding control groups.The expression levels of Nampt,IRS-2,and PDX-1 were tested by Western blotting assay.The changes of cell cycle were determined by FCM and the cell insulin secretion levels were measured with radioimmunoassay.Results Compared with corresponding control groups,the expression levels of Nampt,IRS-2, and PDX-1 proteins in the NIT-1 cells in various BPM groups were increased (P<0.05 or P<0.01).The G0/G1 phase arrest was relieved (P<0.01)when the cells was cultured in low glucose (5.6 mmol·L-1 )condition,and the G2/M block was remitted significantly in high glucose (27.6 mmol·L-1 )condition (P<0.01),furthermore, the cell insulin secretion was promoted compared with control groups except 1 1.1 mmol· L-1 glucose group (P<0.01).Conclusion BPN can promote the expression levels of Nampt,ISR-2 and PDX-1 proteins in NIT-1 cells. There is close relationship between the Nampt expression in NIT-1 cells and insulin signaling pathway and BPN prevents the cells from insulin resistance.

The effect of AMP-activated protein kinase (AMPK) on KiSS-1 mRNA levels was detected by realtime PCR in the hypothalamic GT1-7 neurons. The promoter activity of KiSS-1 gene was detected by DualLuciferase Reporter Assay System.The effects of AMPK on the protein expression and subcellular distribution of SP1 were determined by Western blot.The results showed that AMPK reduced the mRNA expression and promoter activity of KiSS-1 gene while SP1 increased the promoter activity of KiSS-1 gene. Besides,AMPK alse decreased the translocation of SP1.These results suggest that AMPK may inhibit the expression of KiSS-1 gene by decreasing the translocation of SP1 from cytoplasm to nucleus in the hypothalamus GT1-7 neurons.

TNFR-Fc is an important fusion protein that has great potential in therapeutic and diagnostic applications. We developed an efficient fed-batch process for GS-CHO cells to produce TNFR-Fc. The rationale of this fed-batch process relies on the supply of sufficient nutrients to meet the requirements of cell metabolism. The optimal feed medium was designed through ration design. A metabolically responsive feeding strategy was designed and dynamically adjusted based on the residual glucose concentration determined off-line. In this process, the maximal viable cell density and antibody concentration reached above 9.4x10(6) cells/mL and 207 mg/L, respectively. Compared with the batch process, the newly developed fed-batch process increased the cell yield by 3.4 fold and the final antibody concentration by 3 fold. This fed-batch process would therefore facilitate the production of therapeutic antibody by GS-CHO cells.

Objective To observe the clinical effect of traditional Chinese medicine (TCM) characteristic lung rehabilitation in treatment of patients with chronic obstructive pulmonary disease (COPD) and TCM syndrome of lung and kidney qi deficiency at stable period. Methods Sixty patients with stable COPD and lung and kidney qi deficiency syndrome admitted to the First Affiliated Hospital of Anhui University of Chinese Medicine from June to August 2017 were enrolled, and they were divided into routine treatment group and lung rehabilitation treatment group according to the random number table method, each group 30 cases. The routine treatment group was given Seretide (serevent/futicasone) dry powderi nhalation therapy; on the basis of therapy in the routine treatment group, the lung rehabilitation treatment group was treated with TCM characteristic lung rehabilitation technology (acupoint application + Chinese medicine ionic induction + oral administration of Chinese medicine Liuweibuqi granules, delivery at appropriate intervals); both groups were treated for 2 months. The changes of TCM syndrome score, western medicine symptom score, the times of acute exacerbation of COPD, COPD assessment test (CAT) score, lung function indexes: forced expiratory volume in one second (FEV1), FEV1/forced vital capacity (FVC) were observed before and after treatment in two groups. Results After treatment, TCM syndrome score, western medicine symptom score, CAT score, and after treatment the times of acute exacerbation of COPD in both groups were significantly lower than those before treatment, and the above indexes in the lung rehabilitation treatment group were markedly lower than those in routine treatment group [TCM syndrome score:11.93±1.80 vs. 14.27±2.88, western medicine symptom score: 14.20±2.75 vs. 11.93±4.23, CAT score: 14.87±2.60 vs. 16.23±4.39, the times of acute exacerbation of COPD (times): 0.63±0.49 vs. 0.95±0.83, all P < 0.05]. The improvement of FEV1 in the two groups was not significant; but FEV1/FVC in lung rehabilitation treatment group was obviously higher than that before treatment, FEV1/FVC in lung rehabilitation treatment group was significantly higher than that in the routine treatment group [(57.93±7.27)% vs. (52.49±6.61)%, P < 0.05]. Conclusion The application of TCM characteristic lung rehabilitation in the treatment of COPD patients with stable lung and kidney qi deficiency syndrome based on bronchodilators and glucocorticoids can reduce the number of acute exacerbation, improve the patients' clinical symptoms and living quality, but the improvement of lung function is not significant.

Objective:To investigate the efficacy of intramedullary plus extramedullary fixation in the treatment of fractures of distal radial diametaphyseal transition zone in children.Methods:The data were retrospectively analyzed of the 49 children who had been admitted to Pediatric Orthopedic Hospital, Honghui Hospital Affiliated to Xi'an Jiaotong University from July 2018 to April 2020 for fractures of distal radial diametaphyseal transition zone. There were 30 males and 19 females; 21 left sides, 27 right sides, and one case of bilateral sides. In the operation, an elastic intramedullary nail or Kirschner wire was used for intramedullary fixation while another Kirschner wire was used to fix the cortex at the distal and proximal ends of the fracture. The ranges of wrist motion and Disabilities of the Arm, Shoulder and Hand (DASH) scores at 1 and 9 months after operation were recorded and compared; the incidence of postoperative complications was also recorded.Results:The operation time for the 49 children averaged 45.0 min (from 39 to 51 min). The patients were followed up for 6 to 36 months (mean, 18.6 months). The fracture union time averaged 8.6 weeks (from 6.8 to 10.4 weeks). Needle tract infection developed in one case but the wound was healed after removal of the K-wire after callus formation and oral use of antibiotics for 3 days. Another case reported skin irritation the symptoms of which disappeared after the child reduced activities. The ranges of pronation, supination, flexion and extension of the wrist and DASH score were 47.9°±2.5°, 45.5°±3.0°, 51.2°±1.6°, 53.4°±1.7° and (36.7±4.5) points at one month after operation while they were 85.6°±3.1°, 87.6°±2.1°, 88.8°±2.0°, 88.0°±1.2° and (23.2±8.6) points at 9 months after operation. There were statistically significant differences in the above indexes between one and 9 months after operation ( P<0.05). Conclusion:In the treatment of fractures of distal radial diametaphyseal transition zone in children, intramedullary plus extramedullary fixation is simple in surgical techniques, easily repeatable, slightly invasive, and reliable in fixation.
