Objective To explore the effects of Shaoyao Gancao granule on hair growth,behavior,and the hypothalamic pituitary adrenal(HPA)axis in mice with alopecia areata(AA).Methods Forty-two C3H/HeJ mice were randomly divided into control,model,Shaoyao Gancao granule high-,middle-,low-dose,corticotropin-releasing hormone receptor 1(CRHR1)antagonist,and compound glycyrrhizin tablet(CGT)groups.Photography,dermoscopy,weight analysis,and behavioral measurement were performed.Corticotropin-releasing hormone(CRH),adrenocorticotropic hormone(ACTH),cortisol,glucocorticoid receptor(GR),and brain-derived neurotrophic factor(BDNF)were also assessed.Results Compared with the model group,high-dose Shaoyao Gancao granules improve hair regeneration and weight gain(P<0.05),increased the percentage of total exercise distance and central area exercise distance in an open field test(P<0.05),reduced the immobility time in the forced swimming and tail suspension experiments(P<0.05),reduced peripheral blood levels of CRH,ACTH,and cortisol(P<0.05),and increased expression of GR and BDNF in the hippocampus(P<0.05).Conclusions Shaoyao Gancao granule promotes hair growth and improves behavioral performance in mice with AA.These effects may be related to downregulating CRH,ACTH,and cortisol expression,upregulating GR and BDNF expression,and inhibiting excessive activation of the HPA axis.

Objective To study the prevalence situation of chronic diseases among teachers from some middle and primary schools in Chongqing City.Methods The physical examination data of 6969 teachers in 52 middle and primary schools in a district of Chongqing major city were collected.The survey data of overweight,obesity,hyperlipidemia,osteoporosis,fatty liver and hyperuricemia were statistically analyzed.Results The total morbidity rates of overweight,obesity,hyperlipidemia,osteoporosis,fatty liver and hyperuricemia were 31.3 %,7.5 %,35.1%,34.7 %,22.4 % and 22.2 % respectively.The incidence rates of above diseases had difference among the age periods of ≤44 year old,>44 <60 years old and ≥60 year old (P<0.05).The incidence rate was significantly increased with age increase (P<0.05).The incidence rate of osteoporosis in females was higher than that in males(P< 0.01);while the incidence rate of fatty liver and hyperuricemia in males were higher that in females (P<0.01).Conclusion The incidence of chronic diseases among teachers in middle and primary schools is worth attention.Therefore it is necessary to carry out the health education aiming at the teacher population characteristics,strengthen their heath management and behavior intervention for increasing their health level.

Objective:
Preliminary study on the clinical effect of preoperative ultrasound endoscopy combined with staining labeling technique to locate the actual boundary of esophageal and gastric cancer
Methods:
From September 1, 2015 to October 30, 2017, 18 patients with esophageal adenocarcinoma were enrolled in this study. The actual boundaries of esophageal and gastric-derived adenocarcinoma lesions were localized by endoscopic ultrasonography and staining. There were 10 males and 8 females. After completing the preoperative examination, 1-2 days before operation, endoscopic ultrasonography was used to locate the edge of the lesion. Two point injection of carbon nano suspension was used to mark the location of 1cm at the longest distance from the longitudinal axis of the tumor. According to the length of longitudinal axial staining, the thoracotomy was performed. Intraoperative proximal margin resection was used to send frozen pathology. According to the results of freezing, the operation was decided. After the operation, the specimens from the margin of the tumor were segmented into paraffin section, which was about 0.5cm in each segment, and the tumor cells were observed under the electron microscope at all levels of the paraffin sections.
Results:
The average time of preoperative endoscopic ultrasonography staining was(10.16±1.38) min, and the diameter of nano carbon diffusion was(1.43±0.41)cm. All patients in the operation could clearly see the nano carbon staining area under the naked eye. In the field, the average time of locating lesions was(1.27±0.53)min. 5 patients underwent thoracoabdominal surgery and 13 underwent abdominal surgery. The average length of the cut margin of the tumor was(4.74±1.12)cm, and the frozen pathology of the incision margin was negative, and no additional operation was performed. The routine pathology confirmed that all the specimens were negative.
Conclusion
The staining and labeling technique for adenocarcinoma of the esophagogastric junction under endoscopic ultrasonography can detect the tumor edge and the scope of invasion accurately. It provides guidance and guarantee for the smooth implementation of AEG precision surgery. It is a safe, rapid and effective positioning technique.
