Objective To study the expression of intercellular adhesion molecule-1 ( ICAM-1 ) and vascular cell adhesion molecule-l(VCAM-L) on human mesangial cells (HMC) after stimulation by endothelin-1 (ET-1). Methods The ex-pression of ICAM-1 and VCAM-1 was detected at mRNA and protein levels by using Northern bolt and cell ELISA respectively. Results There was basic mRNA and protein expression of ICAM-1 and VCAM-1 on HMC in the control groups without ET-1. ET-l(10-7mol)augmented the mRNA expression of ICAM-1 and VCAM-1 with the maximum at 4 -8 hr. Increased protein expression of ICAM-1 and VCAM-1 was followed thereafter in a time-depended manner. Conclusion The upregulated expression of ICAM-1 and VCAM-1 by ET-1 may have an important role in the development of glomerulonephritis.

Objective To investigate the incidence and relevant information of preterm birth and the outcomes of preterm infants delivered at various gestational weeks and for different causes. Methods Totally 955 women, who ended their pregnancies before term, and 1066 neonates of the previous mothers were enrolled in this survey, among 15 197 deliveries at Peking University First Hospital, Beijing Gynecological and Obstetric Hospital, Women's and Children's Hospital of Haidian District and Peking University Third Hospital, respectively, from December 1~(st), 2006 to May 31~(st), 2007. Results (1)Incidence of preterm birth: The overall incidence of preterm birth of the 4 hospitals was 6. 3% (955/15 197), and it was 8.1% (125/1549) in Peking University First Hospital, 13.1% (150/1142), which was the highest (P<0.01), in Peking University Third Hospital, 5.5% (369/6656) in Beijing Gynecological and Obstetric Hospital and 34.0% (311/5850) in Women's and Children's Hospital of Haidian District.The preterm birth rate at the two comprehensive hospitals was significantly higher than that of the two specialized hospitals [10.2% (275/2691) vs 5.4% (680/12 506), P <0.01]. (2) Gestational weeks at delivery: The incidence of preterm birth before 34 weeks was 28.5% (272/954) and the number changed to 71.5% (682/954)for those preterm deliveries after 34 weeks. However, this number varied among the 4 hospitals. Peking University First Hospital had the highest incidence of preterm birth before 34 weeks(P< 0.05), and the lowest was found in Women's and Children's Hospital of Haidian District(P<0.01), but no difference was found between Peking University Third Hospital and Beijing Gynecological and Obstetric Hospital. (3) Etiology of preterm birth: Preterm premature rupture of membranes (PPROM) accounted for the most proportion of all preterm birth cases, followed by iatrogenic preterm birth and spontaneous preterm birth. But the causes of preterm birth in the 4 hospitals were different. Peking University Third Hospital had a higher incidence of iatrogenic preterm birth than the others (P<0.01), and Peking University First Hospital had a higher incidence of preterm birth caused by PPROM and lower incidence of spontaneous preterm birth. The first four reasons of iatrogenic preterm birth were preeclampsia (143, 42.0%), fetal distress (58, 17.1%), placenta previa (43, 12.6%) and placenta abruption (33,9.7%). (4) Neonatal outcomes in different hospitals: The neonatal outcomes were quite different among the 4 hospitals due to different causes and different delivery weeks. The highest neonatal mortality rate was found in Beijing Gynecological and Obstetric Hospital (5.4%, 22/408) compared to that in Women's and Children's Hospital of Haidian District (1.3%,4/320) and Peking University Third Hospital (0. 6%, 1/170) (P< 0.01), but without any difference when compared to that in Peking University First Hospital (2.4%, 3/ 124) (P>0.05). (5) Neonatal outcomes at different gostational age: The recovery rate of preterm infants delivered at <32 weeks was lower than those delivered ≥32 weeks (P<0.01), and this number rose to 99. 6% in those delivered ≥34 weeks. More infants delivered <32 weeks were given up for treatment or died during the perinatal period than those delivered ≥32 weeks, with the neonatal mortality rate of 22.1% for those delivered at <32 weeks and only 0.3% for those delivered at ≥ 34 weeks (P<0.01). (6) Neonatal outcomes for various causes: The premature neonatal mortality rate for iatrogenic preterm births was higher than that of PPROM (4.9% vs 1.6%, P<0.05). But the neonatal recovery rates were similar among the PPROM, spontaneous and iatrogenic preterm birth group (P>0.05). Conclusions Preterm birth is associated with high perinatal mortality rate, especially for those delivered before 32 weeks which would be highlighted in prevention. Reduction of the iatrogenic preterm birth, combined with proper prevention of PPROM, is an important issue in decreasing the prevalence of preterm birth.

BACKGROUND:
Cardiovascular (CV) disease is the leading cause of morbidity and mortality in adults with type 2 diabetes (T2D). The aim of this study was to determine the CV risk in Chinese patients with T2D based on the 2019 European Society of Cardiology (ESC) and the European Association for the Study of Diabetes (EASD) guidelines on diabetes, pre-diabetes, and CV diseases.
METHODS:
A total of 25,411 patients with T2D, who participated in the study of China Cardiometabolic Registries 3B study, were included in our analysis. We assessed the proportions of patients in each CV risk category according to 2019 ESC/EASD guidelines.
RESULTS:
Based on the 2019 ESC/EASD guidelines, 16,663 (65.6%), 1895 (7.5%), and 152 (0.6%) of patients were included in "very high risk," "high risk," and "moderate risk" categories, respectively. The proportions of patients in each category varied based on age, sex, body mass index, and duration. While 58.7% (9786/16,663) of elderly patients were classified to "very high risk" group, 89.6% (3732/4165) of patients with obesity were divided into "very high risk" group. Almost all patients with a duration of diabetes >10 years had "very high risk" or "high risk." However, 6701 (26.4%) of Chinese T2D patients, who had shorter duration, and one or two risk factors, could not be included in any category (the "unclear risk" category).
CONCLUSIONS
In China, most patients with T2D have "very high" or "high" CV risk based on 2019 ESC/EASD guidelines. However, the risk of patients in "unclear risk" group needs to be further classified.

OBJECTIVE:
To observe the skin surface microcirculation of acupoints of conception vessel, governor vessel and thoroughfare vessel in patients with primary dysmenorrhea using laser speckle contrast imaging (LSCI), and provide acupoint selection basis of acupuncture-moxibustion for primary dysmenorrhea.
METHODS:
Ninety-nine healthy female college students with regular menstrual cycles (normal group) and 94 female college students with primary dysmenorrhea (dysmenorrhea group) were recruited. Before menstrual period, on the first day of menstruation, and on the third day after menstruation, LSCI was used to observe the surface microcirculation at the abdominal acupoints of conception vessel, i. e. Yinjiao (CV 7), Qihai (CV 6), Shimen (CV 5), Guanyuan (CV 4), Zhongji (CV 3) and Qugou (CV 2), acupoints of thoroughfare vessel, i. e. Huangshu (KI 16), Zhongzhu (KI 15), Siman (KI 14), Qixue (KI 13), Dahe (KI 12), Henggu (KI 11) and acupoints of lumbosacral region of governor vessel, i. e. Xuanshu (GV 5), Mingmen (GV 4), Yaoyangguan (GV 3), Yaoshu (GV 2) as well as two non-acupoints.
RESULTS:
Before menstrual period, there was no significant difference in the surface blood perfusion of the acupoints between the dysmenorrhea group and the normal group (P>0.05). On the first day of menstruation, the surface blood perfusion of Xuanshu (GV 5), Mingmen (GV 4), Yaoyangguan (GV 3) and right Huangshu (KI 16) in the dysmenorrhea group was higher than that in the normal group (P<0.05, P<0.01). On the third day after menstruation, the surface blood perfusion of the right Henggu (KI 11) in the dysmenorrhea group was lower than that in the normal group (P<0.05).
CONCLUSION
In patients with primary dysmenorrhea, on the first day of menstruation, the surface blood perfusion of Xuanshu (GV 5), Mingmen (GV 4), Yaoyangguan (GV 3) of governor vessel, and the right Huangshu (KI 16) of thoroughfare vessel is increased, while on the third day after menstruation, the surface blood perfusion of the right Henggu (KI 11) of thoroughfare vessel is decreased. These findings might provide a basis for acupoint selection in the acupuncture-moxibustion treatment of primary dysmenorrhea.
