AIM: Although the evidence indicates that extracellular matrix metalloproteinase inducer (EMMPRIN) is closely associated with matrix metalloproteinase (MMP) expression in tumor cells, tumor invasion and metastasis, no direct proof that EMMPRIN regulates MMPs in monocytes, especially in the atherogenic milieu is observed. Here we tested this hypothesis by examining MMP-9 expression in macrophages/foam cells and monocyte migration through EMMPRIN knockdown by siRNA. METHODS: The methods of qPCR and Western blotting were used to detect the suppressions of EMMPRIN mRNA and protein expression in macrophages and foam cells transfected with EMMPRIN-specific siRNA. The protein expression of MMP-9 in macrophages and foam cells was also determined. Monocyte migration after EMMPRIN knockdown was observed by a Transwell assay. RESULTS: EMMPRIN knockdown by siRNA markedly abolished the MMP-9 expression by 50% and 40% in macrophages and foam cells, respectively. Migration induced by chemotactic factor MCP-1 and VEGF was significantly attenuated (P<0.05) in monocytes treated with EMMPRIN-siRNA. CONCLUSION: The protein expression and secretion of MMP-9 are down-regulated by EMMPRIN knockdown during monocyte differentiation into macrophages and foam cells. Moreover, EMMPRIN siRNA treatment also prevents monocyte migration. Thus, EMMPRIN plays a key regulatory role for MMP activity and monocyte migration, making it a potential target for pharmacological intervention of atherosclerosis.

OBJECTIVETo explore the effect and feasibility of acupuncture in uterine involution after cesarean section.

METHODSSeventy cases of cesarean section in primipara were randomized into an observation group (33 cases) and a control group (37 cases). In the control group, the conventional treatment was adopted after cesarean section. In the observation group, on the basic treatment as the control group, acupuncture was applied at Sanyinjiao (SP 6), Hegu (LI 4), Qihai (CV 6) and Guanyuan (CV 4). In 2 h after operation, acupuncture started, once a day, continuously for five times. The daily height of uterine fundus, daily uterine fundus decreasing degree, postpartum blood loss, lochia duration and ultrasonic B test in 42 days of postpartum were compared between the two groups.

RESULTSThe therapeutic methods of the two groups all promoted uterine contraction. The postpartum height of uterine fundus in the observation group was lower than that in the control group (all P<0.05) and the uterine fundus decreasing degree was higher than that in the control group (all P<0.05). The blood loss in 2 h, 6 to 12 h and 24 to 48 h of postpartum was less than that in the control group (all P<0.05). The lochia duration in the observation group was shorter than that in the control group (P<0.05).

CONCLUSIONAcupuncture promotes uterine contraction, reduces postpartum blood loss and lochia duration and benefits uterine involution after cesarean section.

Taking the Ligustrum lucidum extract as an example, this study investigated the influence of external mechanical forces under different processing conditions on the crystallographic solid form and the key parameter of drug dissolution rate, so as to provide guidance for the preparation and quality control of traditional Chinese medicine preparations. Under different pulverization and tableting conditions, the change of crystallographic solid form of L. lucidum extract was observed by polarizing light microscope. Meanwhile, the effect of this change on the dissolution rate was investigated, and the mathematical relationship between crystal content and dissolution rate was analyzed. The results showed that the process of ball milling and tableting had a significant impact on the crystallographic solid form of L. lucidum extract. The amorphous extract displayed crystal transformation, which induced a significant decline in dissolution rate. Further studies revealed that there was a negative linear relationship between crystal content and dissolution rate. The results of this study indicated that the crystallographic solid form transformation of traditional Chinese medicine extracts might occur during the preparation process, which may cause potential risks to the quality of traditional Chinese medicine preparations. It is suggested that we should pay attention to and strengthen the investigation of the crystallographic solid form during the preparation process, so as to guarantee the safety, effectiveness, and quality controllability of traditional Chinese medicine preparations.

OBJECTIVETo observe the effect of purgation and detoxification therapy on gastrointestinal dysfunction of critically ill patients undergoing abdominal surgery.

METHODSTotally 56 inpatients with severe gastrointestinal dysfunction after abdominal surgery at ICU of Guangdong Provincial Hospital of Traditional Chinese Medicine were assigned to the treatment group and the control group, 28 in each group. All patients received routine Western medical treatment. Patients in the treatment group additionally took Modified Huanglian Jiedu Decoction (MHJD) and received electroacupuncture (EA) for 7 days. The first exhaust time, defecation time, scores for gastrointestinal dysfunction, mechanical ventilation time, ICU hospitalization time, and 28-day fatality rate were observed. Furthermore, serum levels of diamine oxidase (DAO) and D-lactic acid were detected at day 1, 3, and 7 after treatment.

RESULTSThe first exhaust time and the first defecation time in the treatment group were ahead of schedule, when compared with those of the control group (P <0. 05). Scores for gastrointestinal dysfunction, mechanical ventilation time, serum levels of DAO obviously decreased in the treatment group (P <0. 05). There was no statistical difference in serum levels of D-lactic acid, ICU stay time, the incidence of pulmonary infection, and 28-day mortality between the two groups (P >0. 05). Results of Logistic analysis showed that scores for gastrointestinal dysfunction were related with the incidence of pulmonary infection (P <0. 05).

CONCLUSIONMHJD combined EA could promote the recovery of gastrointestinal function in critically ill patients after abdominal surgery via improving intestinal barrier function, which was benefit for shortening mechanical ventilation time.
