Objective To explore serum IL-6 (interleukin-6) ,IL-10 (interleukin-10), the WBC (white blood cell count), CRP (C-reactive protein)and PCT ( procalcitonin ) level in early diagnosing of in children with hand, foot and mouth disease and bacterial infection. Methods 63 children in bacterial infection group and virus infection group respectively,collected 63 children in normal control group by physical examination. Enzyme-linked immunosorbent assay (ELISA) double antibody clamp method was used to determine serum IL-6 and IL-10 level. Immune turbidimetric , enzyme-linked fluorescent were used to detected serum CRP , PCT. WBC results were also compared. Resluts Serum IL-6, IL-10, CRP and PCT level were higher in normal control group compared with virus infection group , the WBC level was slightly lower than normal control grou with statistically different IL-6, IL-10, CRP level (P < 0.05);serum IL-6, IL-10, WBC, CRP and PCT levels in Bacteria infection group were higher than virus infection group and normal control group , while their serum WBC, CRP and PCT level were statistically significant compared to virus infection group (P < 0.05),IL-6 and IL-10 were no statistical different (P > 0.05). Conclusion IL-6, IL-10 levels increased significantly in the early stage of hand,foot and mouth disease, but in the aspect of combination of bacterial infection and bacterial infection, their clinical value was not so significant. WBC, CRP and PCT level had important value for early diagnosis in hand, foot and mouth disease with bacterial infection.

Objective To evaluate the effects of different smoking cessation interventions on cigarette consumption for young soldiers.Methods Sixty-eight soldiers were prospectively investigated in this randomly controlled clinical trial and assigned to the psychological intervention group,auricular acupuncture group,and smoking cessation medication group.Results All the participants showed significant reduction(33.3％ to 73.9％)in post-treatment cigarette consumption.The highest quit rate was found at 7 days,although this declining trend was faded over time.One-year follow-up indicated a 6-month quit rate of 16.7％,23.8％ and 30.4％ in three groups,respectively.Conclusion Psychological intervention,auricular acupuncture and smoking cessation medication may be effective methods of reducing cigarette consumption and improving quit rate in young soldiers.

OBJECTIVETo investigate the role of endogenous hydrogen sulfide (H2S) in erectile dysfunction (ED) induced by androgen deficiency.

METHODSWe randomly divided 30 eight-week-old healthy male SD rats into six groups: 2-week control (A), 4-week control (B), 2-week castration (C), 4-week castration (D), 2-week castration + androgen replacement (E), and 4-week castration + androgen replacement (F), those in groups E and F subcutaneously injected with testosterone propionate (TP) at the physiological dose of 3 mg/kg per day after castration, while those in the other groups with isodose oil instead. At 2 and 4 weeks after operation, we determined the level of serum testosterone (T) , intracavernous pressure (ICP) , mean carotid arterial pressure (MAP) of the rats, measured the concentration of H2S in the plasma and corpus cavernosum tissue, and detected the expressions of cystathionine-P3-synthase (CBS) and cystathionine-gamma-lyase (CSE) by immunohistochemistry and Western blot.

RESULTSThe serum T level was significantly lower in group C ([0.63 +/- 0.15] nmol/L) than in A ( [ 16.55 +/- 4.17] nmol/L) and E ( [ 18.99 +/- 4.62] nmol/L) (P <0.05), as well as in group D ([0.70 +/-0.22] nmol/L) than in B ([15.44 +/-5.18] nmol/L) and F ([20.99 +/-6.41] nmol/L) (P <0. 05) , and so were ICP/MAP after 5 and 7 V electrical stimulation of the pelvic ganglia (P <0. 05) , H2 S concentration (P <0.05), and the expressions of CBS and CSE (P <0.05). The expressions of CBS and CSE proteins were also significantly decreased in group C as compared with D (P <0.05).

CONCLUSIONThe reduced expressions of CBS and CSE may inhibit the H2 S signaling pathway, which might be one of the mechanisms underlying androgen deficiency-induced ED in rats.

AIM: To investigate the antitumor activity and mechanism of Paecilomyces tenuipes polysaccharide(PTPS).METHODS: PTPS-I was obtained by water extraction and alcohol precipitation,and purified by DEAE-cellulose and Sephadex G-100 chromatography.Human erythroleukemia cell line K562,laryngocarcinoma cell line Hep2 and hepatic carcinoma cell line SMMC-7721were co-cultured with PTPS-I or the conditioned medium which prepared with PTPS-I-stimulated human mononuclear cells(PTPS-I-MNC-CM),and the proliferation of tumor cells was determined.The cell counting kit-8(CCK-8) was used to determine the proliferation of MNCs.The FQ-RT-PCR was applied to investigate the expression of TNF-? and IL-6 mRNA in MNCs.RESULTS: PTPS-I-MNC-CM inhibited the proliferation of K562,Hep2 and SMMC-7721 cells in vitro(P

Aim To study the effect of melatonin on expression and activity of myosin light chain kinase in the artery wall of atherosclerotic rabbits.Methods The rabbit model of atherosclerosis was induced by a high-cholesterol diet.The blood lipid levels were assayed in the serum of each group.MLCK expression was detected by Western blot and immunohistochemical method.MLCK activity was measured by ?-32P-ATP incorporation into myosin light chain.Results The atherosclerosis model was established successfully.The levels of lipids decreased after MLT treatment.After fed with cholesterol for twelve weeks,the expression and activity of MLCK in the artery of atherosclerotic rabbits increased markedly,whereas there was no obvious difference in expression of MLCK in the artery of atherosclerotic rabbits fed with cholesterol and melatonin for twelve weeks compared with that of control.Conclusions It was suggest that high expression and activity of MLCK in the artery might be closely correlated with the development of atherosclerosis.Melatonin played an important role in inhibiting the development of atherosclerosis by decreasing the expression and activity of MLCK.

Objective To investigate the clinical characteristics of patients with idiopathic pulmonary arterial hypertension (IPAH) in China.Methods A total of 161 patients diagnosed as IPAH in Shanghai Pulmonary Hospital from June 2008 to June 2010 were retrospective analyzed.Results The mean diagnostic age was (33 ± 15 ) years old and 70.2％ patients were female. The median duration from symptoms onset to diagnostic right heart catheterization was 12 months.Incidence of NYHA class Ⅲ to Ⅳ was 56.5％ at diagnosis and the mean six minutes walk distance was limited to (398 ± 108) meters.Incidence of mild obstructive,restrictive and diffusing impairment in pulmonary function test was 7.8％,42.2％ and 82.2％ patients with IPAH,respectively. Right heart catheterization demonstrated severe elevated mean pulmonary arterial pressure [ ( 63 ± 17 ) mm Hg ( 1 mm Hg =0.133 kPa) ] and pulmonary vascular resistance index [ ( 25 ± 12 ) Wood U/m2 ] in this patient cohort.The response rate of acute pulmonary vasoreactivity testing was 8.7％ in this cohort. Compared with non-responders,responders to acute pulmonary vasoreactivity testing were younger and with less severe pulmonary hypertension. Among non-responders,89％ patients were treated by one specific anti-pulmonary arterial hypertension drug and 27％ patients received combined anti-pulmonary arterial hypertension medications.Conclusions Young female was predominantly involved in patients with IPAH in China.The diagnosis of IPAH is often made at advanced disease stage and majority patients with IPAH received specific anti-pulmonary arterial hypertension therapies in this patient cohort.

Objective To investigate the effect of occipitocervical fusion in patients with craniovertebral junction deformity combined with atlantoaxial instability. Methods The clinical data of 59 patients with craniovertebral junction deformity combined with atlantoaxial instability from March 2013 to June 2017 were retrospectively analyzed. The patients were treated with occipitocervical fusion. The atlantoaxial distance (ADI), distance between the odontoid and Chamberlain line and cervicomedullary angle (CMA) were used to evaluate atlantoaxial dislocation, vertical displacement and spinal cord compression, and the Japan Orthopedic Association (JOA) score was used to evaluate the effect before operation and 7 days after operation. Results The operation time was 109 to 214 (148.5 ± 20.1) min, the transoperative bleeding was 55 to 210 (122.0 ± 16.7) ml, and no injury of spinal cord nerve and vertebral artery occurred during operation. The CMA and JOA score 7 d after operation were significantly higher than that before operation: (153.8 ± 5.4)° vs. (131.2 ± 7.1) ° and (12.7 ± 1.8) scores vs. (10.6 ± 1.4) scores, and the ADI and distance between the odontoid and Chamberlain line 7 d after operation were significantly lower than that before operation: (2.9 ± 0.7) mm vs. (8.3 ± 2.7) mm and (3.2 ± 1.4) mm vs. (8.2 ± 2.3) mm, and there were statistical difference (P＜0.05). One case (1.7%, 1/59) died of massive brainstem infarction 1 d after operation; 2 patients (3.4%, 2/59) had undergone a revision operation due to fusion failure 3 months after operation; other 56 patients in reduction, internal fixation and bone graft fusion. The patients were followed up for 6 to 38 (15.9 ± 7.2) months, and the symptom relief was in 56 cases. The rate of symptom relief was 94.9% (56/59). The JOA score at last follow-up was significantly higher than that before operation: (13.3 ± 1.8) scores vs. (10.6 ± 1.4) scores, and there was statistical difference (P＜0.05). Conclusions The occipitocervical fusion can effectively relieve spinal cord compression and atlantoaxial instability in patients with craniovertebral junction deformity combined with atlantoaxial instability.

Glycogen storage disease type II (GSD II) is an autosomal recessive disorder caused by a deficiency of the lysosomal glycogen-hydrolyzing enzyme acid α-glucosidase (GAA) and can affect multiple systems including the heart and skeletal muscle. The aim of this study was to investigate three children with GSD II confirmed by GAA gene analysis and to report their clinical characteristics and gene mutations. One case was classified as infantile-onset GSD II, and two cases as late-onset GSD II. The infantile-onset patient (aged 4 months) showed no weight increase and had dyspnea, muscle hypotonia, and increased alanine aminotransferase and creatine kinase; echocardiography showed hypertrophic cardiomyopathy. The late-onset patients (aged 8 years and 13 years respectively) showed persistently elevated liver enzymes; one of them had recurrent respiratory tract infection and restrictive ventilation disorder, and the other case showed significantly increased creatase but normal electromyographic findings. Peripheral blood genetic testing for GAA gene showed six pathogenic mutations in the three cases, and the mutations c.2738C>T and c.568C>T had not been reported. Therefore, peripheral blood genetic testing for GAA gene is an effective diagnostic method.
