GWG was a risk factor for LGA (OR1.12, 95% CI 1.09-1.14, P0.000) and macrosomia (OR1.14, 95% CI 1.11-1.16, P0.000). The GWG was positively associated with gestational age (β0.03, 95% CI 0.03-0.04, P0.000). The incidence of the premature delivery decreased with the increasing of GWG (OR0.91, 95% CI 0.88-0.95, P0.000). Women with insufficient GWG exhibited increased risks of SGA infants (OR1.54, 95% CI 1.22-1.94, P0.000) and premature delivery (OR1.53, 95% CI 1.03-2.26, P0.034), whereas women with excessive GWG exhibited increased risk of LGA (OR2.20, 95% CI 1.71-2.84, P0.000) and macrosomia (OR2.41, 95% CI 1.86-3.11, P0.000), when compared with women who had normal GWG. Conclusion · It is of great significance to maintain proper GWG and to improve the outcome of birth. Attention should be paid to the management of weight during pregnancy. Related Articles | Metrics

Advances in function and ligands of transient receptor potential melastain 2 channels LIU Han-wei, YU Dong-zhen, YIN Shan-kai 2018, 38 (12):  1484.  doi: 10.3969/j.issn.1674-8115.2018.12.016 Abstract ( 981 )   PDF (7358KB) ( 568 )   As nonselective cation channels, transient receptor potential melastain 2 (TRPM2) channels are widely distributed in the brain, mainly mediate the inflow of Na+ and Ca2+, leading to cell depolarization and the increasement of intracellular concentration of Ca2+, which are involved in many physiological and pathophysiological processes. Due to increased calcium concentration or oxidative stress, channel gating is inducedeither direct or indirect formation of adenosine diphosphate ribose (ADPR) that binds to a NUDT9 homology domain (NUDT9-H) in the channel. There is no specific TRPM2 antagonist so far. Considering some pathological processes are mediatedTRPM2 channels, the study and discovery of specific TRPM2 blockers might contribute to the effective treatment of many related diseases.

Methods · A sample of 124 inpatient schizophrenics who were diagnosed according to International Classification of Diseases 10th Revision in Shanghai Mental Health Center and collectedconvenience sampling, were interviewedquestionnaire. Item analysis, internal consistency, construct validity and criterion validity were tested using total sample. Patient-Doctor Relationship Questionnaire-15 (PDRQ-15) and Chinese version of Wake Forest Physician Trust Scale (WFPTS) were used as criteria to test criterion validity. Results · Exploratory factor analysis extracted two dimensions labeled “goal and task” and “affective bond”, and the cumulative variance contribution rate was 63.99%. Confirmatory factor analysis showed that the two-factor model had higher adjusted goodness of fit index. The scores of scale and its two dimensions exhibited positive correlations with PDRQ-15 and WFPTS (r0.324-0.726, P<0.01). The internal consistency of the scale (Cronbachs α coefficient) was 0.864, and split-half reliability was 0.919. Conclusion · The Chinese version of WAI-SR is accepin reliability and validity and can be recommended for alliance assessment in the inpatients with schizophrenia. Related Articles | Metrics
