Chinese Journal of Information on Traditional Chinese Medicine 2015;(6):25-27
Objective To discuss the correlation between the distribution of TCM constitutional types and carotid artery intima-media thickness (CIMT) in patients with subclinical hypothyroidism;To select the biased constitution type with high risk factors for atherosclerosis;To provide theoretical basis for preventing this disease from the perspective of TCM physique. Methods Totally 120 patients with subclinical hypothyroidism and 50 cases of normal healthy subjects were selected. TCM constitutional types of two groups were distinguished by KY3H TCM physique recognition software. CIMT was determined, and the correlation between the distribution of TCM constitutional types and CIMT in patients with subclinical hypothyroidism was analyzed. Results In 120 cases of subclinical hypothyroidism, there were 3 cases of gentleness type (2.50%), 30 cases of qi-depression type (25.00%), 28 cases of qi-deficiency type (23.33%), 25 cases of yang-deficiency type (20.83%), 13 cases of phlegm-damp type (10.84%), 9 cases of yin-deficiency type (7.50%), 6 cases of blood stasis type (5.00%), 5 cases of dampness heat type (4.17%), 1 case of particular type (0.83%). The main TCM constitutional types of subclinical hypothyroidism were qi-depression type, qi-deficiency type, yang-deficiency type and phlegm-damp type. The morbidity of atherosclerosis in patients with qi-depression type and qi-deficiency type were higher than other constitutional types. Conclusion The main TCM constitutional types of subclinical hypothyroidism were qi-depression type, qi-deficiency type, yang-deficiency type and phlegm-damp type.

China Medical Equipment 2017;14(8):144-147
Objective:To explore the status and characteristic of psychology for primipara and gravida with second child so as to improve psychological status of them and take them keep positive mentality in whole gestation.Methods: 176 gravidas randomly were selected in this study, and a self-designed questionnaire of psychology was applied to evaluate and compare the psychological status and self-care capacity between primipara and gravida with second child by using method of questionnaire survey. The primipara and gravida with second child were implemented hierarchical management depended on their differently psychological problem, and personalized intervening measurement was adopted to enhance their self-care capacity.Results: The psychological enduring capacity, self-care capacity and the ability of deal with problem about interpersonal relationship of gravidas with second child were obviously better than that of primiparas, while the neglect degree for antenatal care of them was higher than that of primiparas.Conclusion: The whole society should pay attention to the process for gestation of pregnant woman, and give them higher social support so as to promote the maternal and child health and effectively decrease the occurrence rate of delivery risk.

Chinese Journal of Primary Medicine and Pharmacy 2015;22(3):357-359,后插2
Objective To observe the level of urinary microalbumin(MAU) and carotid artery intima-media thickness(CIMT) in patients with subclinical hypothyroidism,and to explore the relationship between subclinical hypothyroidism and MAU,arteriosclerosis.Methods 70 patients with subclinical hypothyroidism were randomly divided into the two groups according to the level of CIMT.33 patients were selected as the arteriosclerosis group and 37 patients were selected as the non-arteriosclerosis group,and 30 healthy people were selected as the control group.The levels of FT3,FT4,TSH,blood fat,MAU,CIMT observed.Results Compared with the healthy controls,the levels of TC,TG,LDL-C,CIMT were significantly higher in the arteriosclerosis group (P =0.008,0.007,0.009,0.006),the level of HDL-C was significantly lower in the arteriosclerosis group(P =0.006).The levels of TC,TG,LDL-C,CIMT were significantly higher in the non-arteriosclerosis group (P =0.042,0.037,0.008,0.035),the level of HDL-C was significantly lower in the non-arteriosclerosis group(P =0.038).The levels of TC,TG,LDL-C,CIMT in arteriosclerosis group were significantly higher than those in the non-arteriosclerosis group (P =0.032,0.041,0.039,0.007).The level of HDL-C in the arteriosclerosis group was significantly lower than the non-arteriosclerosis group(P =0.044).The level of MAU had no significant difference among the three groups(P =0.052,0.087,0.092).TSH had no relationship with MAU (r =0.195,P > 0.05),TSH had positive correlation with CIMT(r =0.578,P < 0.01).Conclusion The patients with subclinical hypothyroidism have lipid metabolism disorder and CIMT incrassation,which can increase the risk of arteriosclerosis.

Objective To explore the expression of aquaporin (AQP)-4 in white matter of spinal cord after spinal cord contusion (SCC). Methods 88 adult Sprague-Dawley rats were assigned randomly to sham operation group and SCC group. The model was established by Al-len's method. BBB sore was used to assess the motor function of rats. The relative expression of AQP-4 mRNA was determined by Q-PCR technique. The localization of AQP-4 was observed by immunohistochemistry. Results BBB score showed motor dysfunction in SCC group, and it increased 7 and 14 days after SCC (t>5.061, P<0.001). The level of AQP-4 mRNA decreased on the 1st and 3rd days (t>50.44, P<0.001), and increased on the 5th day (t=-3.968, P=0.001), and lasted until the 28th day (t=-4.227, P=0.001) compared with that on the 3rd day. The immunohistochemistry showed AQP-4 was located on the process of glial cell and vascular endothelial cells in white matter of spi-nal cord. Conclusion AQP-4 may play various roles at different stages in SCC.

BACKGROUND:Induced pluripotent stem cel technology have solved the contradiction between the ethics and immune rejection, and this high-efficient and safe technique is becoming the mainstream of today’s research. OBJECTIVE:To comprehensively review the safety and application of induced pluripotent stem cel s.METHODS:A computer-based online retrieval of PubMed and CNKI was performed to search relevant papers published from January 2006 to April 2016, with the key words of“induced pluripotent stem cel , reprogramming, clinical application, safety, transcription factor, disease mode”in English and Chinese, respectively. RESULTS AND CONCLUSION:In recent years, research on induced pluripotent stem cel s has attracted much attention from the scientific community and the medical community, and this technique has successful y gained induced pluripotent stem cel s and overcome the problems of immunity and ethics. However, it is limited to the theoretical and laboratory research due to the inability to solve the safety, efficiency and re-differentiation mechanism of induced pluripotent stem cel s. Therefore, we are faced with enormous difficulties and chal enges, which involve al aspects of basic research, including how to safely and effectively induce the differentiation of induced pluripotent stem cel s into the desired cel type and how to establish a suitable disease model as wel as a high-throughput drug screening platform.

Objective:The effect of naltrexone on function of murine peritoneal macrophage in vitro was studied in order to illuminate its immune activity futher. Methods:Peritoneal macrophages were divided in three groups:RPMI1640 blank control group, LPS positive control group and NTX treated group. Various phenotypic and functional indices were tested by MTS, flow cytometry technology,phagocytosis experiment and ELISA. Results: Compared with RPMI1640 group,at a LDN exhibits paradoxical properties;the expression of CD64 on surface increased while the expression of CD206 decreased in NTX group;the expression of tumour necrosis factor-α(TNF-α),interleukin-6(IL-6),interleukin-1β(IL-1β)were increased. Conclusion:The results of experiment had proved that LDN could influence macrophage polarzation, regulate the inflamatory mediators production and affect the phagocytosis function of peritoneal macrophage.

Objective: To compare the volatile compounds extracted from Rhodiola renulata respectively by HS-SPME and SD. Methods:The volatile constituents from Rhodiola crenulata were extracted respectively by HS-SPME and SD, and then the contents and the names were confirmed by GC-MS. Results:Totally 39 compounds were identified from Rhodiola crenulata by HS-SPME while 16 ones were identified by SD. Among them, 4 common compounds were detected. Conclusion: There are some differences between the two methods. Compared with SD, HS-SPME is obviously better because more volatile constituents can be extracted from the herb, furthermore, HS-SPME has notable advantages of higher retrieval matching and sensitivity.
