[Clinical observation of rapid massage at Shuidao (ST 28) to prevent postpartum urinary retention].

OBJECTIVE: To explore the clinical effect of rapid massage at Shuidao (ST 28) to prevent puerpera from postpartum urinary retention. METHODS: A total of 200 puerpera giving birth through vagina were enrolled and divided into an observation group and a control group according to the random number table method, 100 cases in each group. In the observation group, rapid massage at Shuidao (ST 28) was applied. In the control group,there was no intervention and urinated naturally. The traditional Chinese medicine syndrome scale was used to evaluate poor sense of urination, and record puerpera with or without postpartum urinary retention, the poor sense of first urination, the first time of urination, the amount of first urination and postpartum hemorrhage. RESULTS: The poor sense of first urination in the observation group was significantly lower than that in the control (P<0.001), the first time of urination in the observation group was significantly earlier than that in the control group (P<0.001), the amount of first urination in the observation group was significantly more than that in the control group (P<0.001), the observation group was superior to the control group to prevent postpartum urinary retention (P<0.05). CONCLUSION: Rapid massage at Shuidao (ST 28) can reduce the poor sense of first urination, significantly advance the time of spontaneous urination, significantly increase the amount of first urination and effectively prevent postpartum urinary retention.

Dachengqi Decoction Attenuates Intestinal Vascular Endothelial Injury in Severe Acute Pancreatitis in Vitro and in Vivo.

BACKGROUND/AIMS: Dachengqi decoction (DCQD) is a well-known traditional Chinese herbal drug with strong anti-inflammatory effects. Angiopoietin-1 (Ang-1) plays a vital role in maintaining the stability and integrity of the vascular wall and prevents vascular leakage due to inflammatory mediators. Our previous work found that DCQD protects against pancreatic injury in rats with severe acute pancreatitis (SAP). This study aims to investigate the effects of DCQD on intestinal endothelial damage in both damaged human umbilical vein endothelial cells (HUVECs) and SAP rats. METHODS: HUVECs were randomly divided into four groups: control group, TNF-α group, TNF-α plus Ang-1 group (Ang-1 group), and TNF-α plus DCQD group (DCQD group). Cells were incubated for 6 h, 12 h, and 24 h, before collection. The treatment concentration of DCQD was decided based on a Cell Counting Kit-8 (CCK-8) assay. The monolayer permeability of the HUVECs was assessed by measuring the transendothelial electrical resistance (TEER). Apoptosis was analyzed by flow cytometry. mRNA and protein expression of aquaporin 1 (AQP-1), matrix metalloproteinase 9 (MMP9), and junctional adhesion molecule-C (JAM-C) was evaluated by RT-PCR, immunocytofluorescence, and western blot. Forty male Sprague-Dawley rats were randomized into a control group, SAP group, SAP plus Ang-1 group (Ang-1 group), and SAP plus DCQD group (DCQD group). SAP was induced by intraperitoneal injection of cerulein and lipopolysaccharide (LPS), while the control group received 0.9% saline solution. Evans blue was injected through the penile vein and the rats were then sacrificed 12 h after modeling. Levels of serum amylase, TNF-α, IL-1ß, IL-2, and IL-6 were determined by using ELISA. Intestinal tissue was analysed by histology, and capillary permeability in the tissues was evaluated by Evans blue extravasation assay. Protein and mRNA expression of AQP-1, MMP9, and JAM-C were assessed by immunohistofluorescence, western blot, and RT-PCR. RESULTS: DCQD reduced the permeability of HUVEC induced by TNF-α in vitro. Furthermore, DCQD altered the mRNA and protein levels of JAM-C, MMP9, and AQP-1 in HUVECs after TNF-α induction. SAP intestinal injury induced by cerulein combined with lipopolysaccharides was concomitant with increased expression of JAM-C and MMP9, and reduced expression of AQP-1 in intestinal tissue. Pretreatment with DCQD attenuated SAP intestinal injury and lowered the levels of serum amylase, TNF-α, IL-1ß, IL-2, and IL-6 effectively. Our study demonstrated that DCQD decreased the expression of JAM-C and MMP9 and increased the expression of AQP-1 both in vitro and in vivo. CONCLUSION: DCQD can reduce capillary endothelial damage in acute pancreatitis-associated intestinal injury and the mechanism may be associated with the regulation of endothelial barrier function-associated proteins AQP-1, MMP9, and JAM-C.

Susceptibility-Weighted Imaging of the Anatomic Variation of Thalamostriate Vein and Its Tributaries.

BACKGROUND AND PURPOSE: Thalamostriate vein (TSV) is an important tributary of the internal cerebral vein, which mainly drains the basal ganglia and deep medulla. The purpose of this study was to explore the anatomic variation and quality of TSV and its smaller tributaries using susceptibility-weighted imaging (SWI). METHODS: We acquired SWI images in 40 volunteers on a 3.0T MR system using an 8-channel high-resolution phased array coil. The frequencies of the TSV and its tributaries were evaluated. We classified TSV into types I (forming a venous angle) and II (forming a false venous angle). We classified anterior caudate vein (ACV)into types 1 (1 trunk) and 2 (2 trunks) as well as into types A (joiningTSV), B (joining anterior septal vein), and C (joining the angle of both veins). RESULTS: The TSV drains the areas of caudate nucleus, internal capsule,lentiform nucleus, external capsule, claustrum, extreme capsule and the white matter of the frontoparietal lobes,except thalamus. The frequencies of the TSV, ACV and transverse caudate vein (ACV) were 92.5%, 87.5% and 63.8%, respectively. We found TSV types I and II in 79.7%, and 20.3% with significantly different constitution ratios (P< 0.05). The most common types of ACV were type 1 (90.0%) and type A (64.3%). CONCLUSION: The complex three-dimensional (3D) venous architecture of TSV and its small tributaries manifests great variation, with significant and practical implications for neurosurgery.
