Objective To compare the efficacy and safety of the non-invasive high frequency ventilation (NHFV) and non-invasive intermittent positive pressure ventilation (NIPPV)in neonates with respiratory distress syndrome (RDS) after extubation.Method Neonates with RDS from January 2015 to January 2016,who required high frequency ventilation after birth and were extubated after treatment were retrospectively studied.The enrolled patients were divided into NHFV group and NIPPV group to compare the rate of successful extubation within 7 days,non-invasive respiratory ventilation support time and complication incidence.Result In total 42 neonates were included,NHFV group were 21 cases and NIPPV group were 21 cases.The rates of successful extubation were not statistically different (71.4％ vs.80.9％,P ＞ 0.05);Compared with NIPPV group,NHFV group had shorter ventilation time [3.5 (2.2,4.1) d vs.4.6 (2.8,5.3)];the incidence of bronchopulmonary dysplasia,pneumothorax,intraventricular hemorrhage,periventricular leukomalacia,retinopathy of premature and necrotizing enterocolitis between groups were not statistically different (P ＞ 0.05).Conclusion NHFV is a new safe and efficient ventilation support method for extubated neonates,and needs further research.

Objective To evaluate the efficacy of repetitive transcranial magnetic stimulation (rTMS) combined with gabapentin for treatment of recurrent pain after trigeminal radiofrequency thermocoagulation.Methods Forty patients of both sexes suffering from recurrent pain after trigeminal radiofrequency thermocoagulation,who refused surgical treatment,aged 45-80 yr,of American Society of Anesthesiologists physical status Ⅰ or Ⅱ,with visual analog scale score ≥4,with the course of recurrent pain 0.5-17.0 months,were randomized into 2 groups (n =20 each) using a random number table:gabapentin group (group A) and gabapentin plus rTMS group (group B).The patients were treated with 2 courses of rTMS in total (5 days for 1 course,1 time per day) and with the second course at a 2-day interval in group B.Effective analgesia and pain relief were recorded within 6 months after treatment,and the therapeutic efficacy was evaluated according to the modified Macnab criteria.The daily consumption of gabapentin and development of rTMS-and gabapentin-related adverse reactions were recorded.Results No rTMS-related adverse reactions were found in group B.Compared with group A,the rates of effective analgesia and pain relief were significantly increased,the therapeutic efficacy was enhanced,the daily consumption of gabapentin was decreased,and the incidence of gabapentin-related adverse reactions was decreased in group B (P＜0.05).Conclusion Combination of rTMS and gabapentin produces better efficacy than gabapentin alone when used to treat the recurrent pain after trigeminal radiofrequency thermocoagulation,and the safety is good.

Purpose: Gastric cancer (GC) is a malignant tumor with a high mortality rate. Drug resistance is a major obstacle to GC therapy. This study aimed to investigate the role and mechanism of exosomal circPRRX1 in doxorubicin resistance in GC. Materials and Methods: HGC-27 and AGS cells were exposed to different doses of doxorubicin to construct doxorubicin-resistant cell lines. Levels of circPRRX1, miR-3064-5p, and nonreceptor tyrosine phosphatase 14 (PTPN14) were detected by quantitative real-time PCR or Western blot assay. Then, 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide, transwell,and Western blot assays were used to explore the function of circPRRX1 in GC cells. Interactions among circPRRX1, miR-3064-5p,and PTPN14 were confirmed by dual-luciferase reporter assay. The in vivo function of circPRRX1 was analyzed in a xenograft tumor model. Results: CircPRRX1 was highly expressed in doxorubicin-resistant GC cell lines. Knockdown of circPRRX1 reversed doxorubicin resistance in doxorubicin-resistant GC cells. Additionally, extracellular circPRRX1 was carried by exosomes to spread doxorubicin resistance. CircPRRX1 silencing reduced doxorubicin resistance by targeting miR-3064-5p or regulating PTPN14. In GC patients,high levels of circPRRX1 in serum exosomes were associated with poor responses to doxorubicin treatment. Moreover, depletion of circPRRX1 reduced doxorubicin resistance in vivo. Conclusion CircPRRX1 strengthened doxorubicin resistance by modulating miR-3064-5p/PTPN14 signaling and might be a therapeutic target for GC patients.

Objective To analyze the effect of the fracture healing by using selective sensory radicotomy before and after the ganglion.Methods From September,2014 to August,2015,120 rats were averagely divided into 3 groups,which was the sham operate group(SO),the anterior injury of ganglion rhizotomy group (AGR) and the posterior injury of ganglion rhizotomy group (PGR).Tibial transverse fracture was performed on right or left randomly and the fracture was fixed with intramedullary.In coordination with the fractured-side,the selective radicotomy from L4 to L6 was made.The mRNA level of collagen-Ⅰ and collagen-Ⅱ in bony callus was quantified at 3,7 days and 2 weeks after the operation by RT-PCR(n=5).The histological examination,X-ray,biomechanical testing were performed at 4 and 8 weeks.The quantitative data of iconography and biomechanics was acquired by using the relative ration which resulted from fractured-side data dividing the unfractured-side one for every pair tibia in same rat.Results At 3 days after surgery,the mRNA of collagen-Ⅰ were 81.3±11.1,37.5±8.2 and 24.7±9.2,the mRNA of collagen-Ⅱ were 2.4±0.5,2.1±1.0 and 2.9±1.2 in SO,AGR and PGR group respectively;At 7 days after surgery,the mRNA of collagen-Ⅰ were 17.9±5.8,7.2±1.8 and 6.7±2.4,the mRNA of collagen-Ⅱ were 12.5±3.4,2.8±1.3 and 1.2±0.4 in SO,AGR and PGR group respectively.The SO group had significantly upregulation of collagen-Ⅰ and collagen-Ⅱ mRNA compared with the AGR and PGR groups at 3 days and 7 days respectively after surgery(P＜0.05).There was a significant difference of the collagen-Ⅱ between AGR group (2.8±1.3) and PGR group (1.2±0.4) at 7 days after injury(P＜ 0.05).The fracture bony callus in PGR group was a significantly larger and less ossified than that in the AGR group.The mechanical load of fracture in SO group was larger than that of the other 2 groups (P＜0.05).Conclusion Sensory denervation negatively affects fracture-healing.The ganglion of sensory nerve plays an important role in bone fracture healing and normal innervation is essential for the fracture repair.

OBJECTIVE: To determine serum levels of betatrophin in patients with polycystic ovary syndrome (PCOS) and the influential factors. 
 METHODS: A total of 100 PCOS patients were enrolled randomly as a PCOS group, and 40 age-matched healthy women were recruited as a normal control (NC) group. Primary clinical or biochemical parameters of the subjects were detected. The results were analyzed by SPSS 19.0.
 RESULTS: Serum betatrophin levels were elevated in the PCOS group compared with the NC group. Serum betatrophin levels were positively correlated with age and Whole Body Insulin Sensitivity Index (WBISI),and negatively correlated with body mass index, fasting insulin(FINS), homeostatic model assessment insulin resistance (HOMA-IR) and homeostatic model assessment β cell function (HOMA-β). Multiple linear stepwise regression analysis showed that age and waist hip ratio (WHR) were independent influential factors for the level of betatrophin. PCOS was more likely to occur in women with higher betatrophin levels.
 CONCLUSION Serum betatrophin levels increase in women with PCOS and they are independently associated with age and WHR. There is no significant correlation between betatrophin and insulin resistance or insulin levels.
