OBJECTIVE: To evaluate the efficacy of autogenous bone marrow injection and elastic intramedullary injection in the treatment of bone cyst in children. METHODS: From January 2012 to December 2016, 56 children with simple bone cyst were divided into two groups: autogenous bone marrow blood injection group and elastic intramedullary needle group. There were 28 cases in the autogenous bone marrow blood injection group, 16 boys and 12 girls, aged (7.7±1.9) years old, 10 cases of proximal humerus, 8 cases of proximal femur, 6 cases of proximal tibia and 4 cases of femoral shaft. In the elastic intramedullary needle group, there were 28 cases, 18 boys and 10 girls, aged(7.5±2.2) years old, 11 cases of proximal humerus, 7 cases of proximal femur, 5 cases of proximal tibia, 4 cases of femoral shaft and 1 case of distal femur. The treatment effect was evaluated by Capanna standard. RESULTS: All the patients were followed up, including 17 to 35(25.6±4.2) months in the elastic intramedullary needle group and 19 to 35(27.4±4.8) months in the autogenous marrow blood injection group. According to Capanna's evaluation standard of bone cyst, 27 patients in the elastic intramedullary needle group were treated effectively(25 patients cured, 2 patients healed but some remained lesions), 1 patients recurred, 0 patient had no response to treatment; 18 patients in the autogenous bone marrow blood injection group were treated effectively(13 patients cured, 5 patients healed but some remained lesions), 8 patients of cyst recurred, 2 patients had no response to treatment; the difference between the two groups was statistically significant(<0.01). The overall cure time was calculated by the follow-up of 25 cases in the elastic intramedullary injection group and 13 cases in the autogenous marrow blood injection group. The cure time was(20.2±3.5) months in the elastic intramedullary injection group and(27.7±4.9) months in the autogenous marrow blood injection group. The difference was statistically significant(<0.05). CONCLUSIONS For the treatment of bone cyst in children, the therapeutic effect of elastic intramedullary needle is better than that of autogenous bone marrow blood injection, and the cure time is shorter.

OBJECTIVETo study the variation tendency of hypertension in two rural areas in Gansu, and provide epidemiological evidence to evaluate the hypertension of rural residents.

METHODSUsing equidistant random sampling method and cross-sectional sentinel monitoring, two remote natural villages, Yangzhuang and Xiangming, at Yellow river and Yangtze river valley were selected as hypertension monitoring site. From 1990 to 2012, clinical examination to the resident above 18 years old was carried out continuously for 23 years, 11 164 cases were included.

RESULTSHypertension prevalence of tested cases increased with years, Yangzhuang monitoring site increased from 6.9% (16/232) in 1990 to 36.7% (216/597) in 2012 with an increase of 29.8%, and Xiangming monitoring site increased from 3.4% (16/474) in 1995 to 20.6% (120/582) in 2011 with an increase of 17.2%. Total prevalence of Yangzhuang (24.1%, 1505/6240) was significantly higher than Xiangming (11.4%, 578/4924) (χ(2) = 277.9, P < 0.01). Total hypertension prevalence of 18 - 35 years old group was 9.9% (292/2944) in Yangzhuang and 4.2% (63/1495) in Xiangming, Yangzhuang was higher than Xiangming (χ(2) = 43.7, P < 0.01). Total hypertension prevalence of above 35 years old group was 36.8% (1213/3296) in Yangzhuang and 14.1% (515/3429) in Xiangming, Yangzhuang was higher than Xiangming (χ(2) = 417.7, P < 0.01). The growth rates of hypertension prevalence in 18 - 35 years old group of both areas (Yangzhuang: 823.5%, Xiangming: 614.3%) were higher than 35 years old group (Yangzhuang:310.5%, Xiangming: 368.0%), but the hypertension prevalence of above 35 years old group was higher than 18 - 35 years old group. Hypertension prevalence of male was 25.4% (761/2992) in Yangzhuang and 11.7% (238/2047) in Xiangming, Yangzhuang was higher than Xiangming (χ(2) = 145.8, P < 0.01), hypertension prevalence of female was 22.7% (738/3248) in Yangzhuang and 11.2% (340/2877)in Xiangming, Yangzhuang was higher than Xiangming (χ(2) = 125.1, P < 0.01). While the difference between male and female had no statistical significance in both areas.

CONCLUSIONHypertension of the two monitoring points was in high epidemic trend, but with different epidemic trend. From different region and environment research to discuss the cause of hypertension can provide scientific evidence for prevention and control.

This study was aimed to detect the peripheral blood serum neopterin (Npt) level in the patients with hemophagocytic lymphohistiocytosis (HLH) and to explore its significance in HLH. The enzyme-linked immunosorbent assay (ELISA) was applied to detect the serum Npt level and sCD25 level in 20 HLH patients before and after treatment and 15 healthy controls. The results indicated that the serum Npt and sCD25 levels in HLH patients were significantly higher than those in healthy controls (P < 0.0001). The serum Npt and sCD25 levels in the HLH group decreased significantly after treatment, respectively (P < 0.0001). The correlation analysis of Npt with sCD25 before and after treatment showed that they had significant correlation (r = 0.81, P < 0.05 before treatment; r = 0.65, P < 0.05 after treatment). Meanwhile, the level of serum Npt and ferritin had a significant correlation in newly diagnosed HLH patients (r = 0.55, P < 0.05). It is concluded that the serum Npt may play an important role in the HLH pathogenesis, the enhancement of Npt levels has an important significance for diagnosis and evaluation for HLH.

This study was purposed to investigate the molecular mechanism of 4-1BBL reverse signals in the human acute monocytic leukemia cell line of U937. The U937 cell line was used as target cells, and stimulated by the mouse anti-human 4-1BBL monoclonal antibody 1F1. The nuclear translocation of NF-κB and the co-location of 4-1BBL and CD28i molecules in U937 cells were observed with confocal laser scanning microscopy. The protein and m-RNA expression levels of 4-1BBL and CD28i were detected by flow cytometry and RT-PCR respectively. The results showed that the significant nuclear translocation of NF-κB and co-localization of 4-1BBL and CD28i on membrane of U937 cells appeared after being stimulated by mAb1F1. It is concluded that the 4-1BBL reverse signals transduction mediating the growth of U937 cells relates with the nuclear translocation of NF-κB. CD28i may be involved in intracellular 4-1BBL reverse signaling pathways.

OBJECTIVETo evaluate the effectiveness and safety of mosapride on treatment of functional dyspepsia.

METHODSRandomized controlled clinical trial was conducted and patients suffered from functional dyspepsia were included. 5 mg mosapride was given three times daily for 4 weeks in the treatment group. 10 mg domperidone was given three times daily for 4 weeks as control. Changes on symptom score, gastric empty or new occurring events were included as outcomes.

RESULTS231 patients suffered from functional dyspepsia were selected by inclusion and exclusion criteria from August 15 to Oct 22, 1999. Of these, 108 (46.8%) were males, versus 123 (53.2%) females and 118 (51.2%) in the treatment group and 113 (48.9%) as controls. 222 (96.1%) patients were followed up. Results showed that the total efficacy rates in early satiety and abdominal distension were 84.5% and 90.1% in mosapride after the 2 weeks of treatment. Mosapride seemed to be more effective in improving symptoms of belching and heartburn than that in controls (P < 0.05). In 4 weeks, the total efficacy in improving symptoms of abdominal distention and belching showed more effective in mosapride than that in controls (P < 0.05). Decrease of symptoms score was more in mosapride than that in controls (P < 0.05). Mosapride was less effective in controls in improving the gastric empty in terms of proportion (46.2% vs. 25.9%, P = 0.020) and range (46.2% vs. 24.0%, P = 0.003). Side effects would include diarrhea, constipation, headache, dizziness, insomnia, skin scare and the like. There was no significant difference between the two groups (9.6% in mosapride vs. 14.0% in controls).

CONCLUSIONMosapride was safe and effective in improving the symptoms and gastric empty of functional dyspepsia.
