Objective: The incidence and distribution of positional deformities(PD)were studied by measuring cranial types of infants aged 0-6 months of 3 hospitals in Chongqing, and the recommended values of local PD were discussed. Methods: Data of 3 406 infants with 0-6 months head size measurements were collected from the Second Affiliated Hospital of Army Military Medical University, Yongchuan Maternal and Child Health Care Hospital and Wanzhou Maternal and Child Health Care Hospital from September 1, 2017 to August 31, 2018, cranial vault asymmetry(CVA)and cranial index(CI)were calculated.According to different age groups, observe the distribution of cranial types, and use the current international common diagnostic criteria to understand the incidence of cranial abnormalities, and analyze the distribution of percentile values of CVA and CI in infants in Chongqing. Results: According to the current international standard diagnosis of PD, the incidence of simple brachycephaly was the highest(39.9%)in the overall cranial abnormalities of infants, followed by brachycephaly with plagiocephaly was the second(36.1%), simple plagiocephaly was the lowest(6.9%), and normal cranial type only accounted for 17.1%.The detection rates of plagiocephaly(36.9%)and brachycephaly(67.0%)were the lowest in the 0-2 months group, and the highest in the 3-4 months group(47.3%/83.3%), and then decreased in the 5-6 months group(46.6%/80.2%). Conclusion The basic values of cranial type measurement of full-term infants in chongqing were significantly different from international reports, mainly due to the large CI value.The general international diagnosis standard for positional deformities do not conform to Chinese infants.We suggest that the reference value for positional deformities in this region is as follows: CVA≥0.4 cm is abnormal, of which 0.4 cm≤CVA<0.6 cm for mild plagiocephaly, 0.6 cm≤CVA<1.0 cm for moderate plagiocephaly, CVA≥1.0 cm for severe plagiocephaly; 82%≤CI≤91% is abnormal, of which 91%≤CI<94% for mild brachycephaly; 94% ≤CI<99% for moderate brachycephaly; CI≥ 99% for severe brachycephaly.CI≤82% is scaphocephaly.

OBJECTIVETo research the central molecular mechanism of gastric motility in functional dyspepsia (FD) rats treated with electroacupuncture (EA) at and points of stomach.

METHODSA total of 30 SD rats were randomized into a blank group, a model group, a Zhongwan+Weishu group, a Weishu group and a Zhongwan group, 6 rats in each group. FD rats were established by moderate clipping tail infuriation and irregular feeding except in the blank group. EA was used at "Zhongwan"(CV 12),"Weishu"(BL 21), and"Zhongwan"(CV 12) +"Weishu"(BL 21) in the corresponding groups for 7 days, once a day, and 20 min a time. No intervention was used in the blank and model groups. Grabbing and fixation were applied in the model group. Gastric antrum motion range and frequency were recorded by gastrointestinal pressure transducer. The expression of subunit NR1 of N-methyl-D-aspartate recepter (NMDAR) in dorsal motor nucleus of the vagus (DMV) was determined by Western blotting. The content of serum nitric oxide (NO) was measured by ELISA.

RESULTSCompared with the blank group, the gastric antrum motion range and NR1 in the DMV decreased and the serum NO content increased in the model group (all <0.05). Compared with the model group, the gastric antrum motion range and NR1 in the DMV increased and the serum NO content decreased in the three EA groups (all <0.05). Compared with the Zhongwan and Weishu groups, the gastric antrum motion range and NR1 in the DMV increased in the Zhongwan + Weishu group (all <0.05). Compared with Zhongwan + Weishu and Zhongwan groups, the expression of NO in the Weishu group decreased (both <0.05). The gastric antrum motion frequency among the 5 groups had no statistical significance (all >0.05).

CONCLUSIONEA at the and points can regulate the gastric motility in FD rats which may be by modulating the activity of NMDAR in the central DMV region, thus regulating the serum NO content.
