Methods The mice were randomly divided into high concentration of Mieyou Soup group, low concentration of Mieyou Soup group, gastric triad group, model group and control group. BALB/c mice of H.Pylori-associated gastritis mice of Pi-Wei hygropyrexia syndrome model was established by composite factor. After modeling, the mice were administered for of continuous 14 days. The drug dosage of high concentration of Mieyou Soup group, low concentrations of Mieyou Soup group, and gastric triad group were 12.4, 6.2 g/kg, and 0.279 8 mg/kg, respectively. Western Blot was used to detect the expression of HSP70 protein, and immunohistochemistry was employed to detect the expression of AQP4 protein. Results Compared with control group, the expression of HSP70 and AQP4 in model group significantly increased (P<0.05);compared with the model group, the HSP70 in high concentration of Mieyou Soup group, low concentrations of Mieyou Soup group, gastric triad group increased, the AQP4 in high concentration of Mieyou Soup group, low concentrations of Mieyou Soup group, gastric triad group decreased, with statistical significance (P<0.01). Conclusion Mieyou Soup may play a role in treatment of H.Pylori-associated gastritis mice of Pi-Wei hygropyrexia syndrome by raising the expression of HSP70, and reducing the expression of AQP4 protein expression.

This study investigated the abnormal expression of ATP synthase β-subunit (ATPsyn-β) in pancreas islets of rat model of polycystic ovary syndrome (PCOS) with type 2 diabetes mellitus (T2DM),and the secretion function changes after up-regulation of ATP5b.Sixty female SD rats were divided into three groups randomly and equally.The rat model of PCOS with T2DM was established by free access to the high-carbohydrate/high-fat diet,subcutaneous injections of DHEA,and a single injection of streptozotocin.The pancreas was removed for the detection of the ATPsyn-β expression by immunohistochemical staining,Western blotting and reverse transcription-PCR (RT-PCR).The pancreas islets of the rats were cultured,isolated with collagenase Ⅴ and purified by gradient centrifugation,and the insulin secretion after treatment with different glucose concentrations was tested.Lentivirus ATP5b was successfully constructed with the vector of GV208 and transfected into the pancreas islets for the over-expression of ATPsyn-β.The insulin secretion and intracellular ATP content were determined after transfection of the PCOS-T2DM pancreas islets with Lenti-ATP5b.The results showed that the expression of ATPsyn-β protein and mRNA was significantly decreased in the pancreas of PCOS-T2DM rats.The ATP content in the pancreas islets was greatly increased and the insulin secretion was improved after the up-regulation of ATPsyn-β in the pancreas islets transfected with lenti-ATP5b.These results indicated that for PCOS,the ATPsyn-β might be one of the key factors for the attack of T2DM.

BACKGROUND:In recent years, increasing research emphasizes the puncture position of the foramen ovale in skul , but most of the positin methods require a higher personal experience of surgeons and lack of individualized quantitative parameters. OBJECTIVE:To establish a visualized digital model of the foramen ovale in skul , explore the reasonable puncture path and puncture depth of percutaneous treatment of foramen ovale puncture for trigeminal neuralgia, and develop the individualized treatment of trigeminal neuralgia. METHODS:Head CT images from healthy adult male volunteers were obtained and were input into three-dimensional reconstruction software MIMICS 10.01, the three-dimensional visualized models of the skul and skin were established. Using the models, the puncture path of the foramen ovale was designed and the preliminary model of the puncture locator was plotted. RESULTS AND CONCLUSION:The three-dimensional visualized digital model of the foramen ovale puncture path was established with CT scan images by using MIMICS software, which provides reliable anatomical data for clinical teaching and lays the groundwork for the simulation of puncture surgery. On the three-dimensional models, the“needle points”,“target points”, and“midpoint”were determined, and the triangle consisted of the three points was regarded as“positioning plane”. Using these parameters, the positioning instrument is characterized by simple structure, convenient operation, high positioning precision and short period of exposure to radiation, it simulates the foramen ovale puncture needle depth and needle direction in a precise and individualized manner.

OBJECTIVETo elucidate the relationship between collagen degradation and cervical ripening by detecting dynamic expressions of matrix metalloproteinases 2 (MMP-2) and 8 (MMP-8) in rat cervix.
METHODSPF rats were divided into 5 groups (n=6), namely non-pregnancy estrus interval group, gestational days 10, 16, and 19 groups, and immediately postpartum group. The wet weight of the cervix was measured and HE staining was used to display the general structure of the cervix. VG staining was applied to visualize the collagen fibers and muscular fibers. Immunohistochemistry was performed to observe the expressions of MMP-2 and MMP-8 in the cervix.
RESULTSHE staining showed that the rat uterine cervix consisted mainly of fibroblasts and fibrous connective tissues. A small quantity of neutrophils could be seen in the cervix stroma of the rats immediately after immediately parturition, but not at the other time points. The wet weight of the antepartum cervix had increased, and a more obvious increase was seen in the wet weight of the cervix immediately after parturition. The collagen fibers of the cervix consisted of collagen fibers and smooth muscle fibers, and their proportions showed no significant variation at the time points around the parturition. Immediately after parturition, the collagen fibers and muscular fibers in the cervix became loosened as compared with that before parturition. MMP-2 expression was found in the cervical stroma but not in the squamous epithelium in nonpregnancy, term pregnancy, and immediately after parturition; the smooth muscle cells, vascular wall, and stromal fibroblasts showed positive expression of MMP-2. Enhanced intensity of MMP-2 staining was seen in term pregnancy and postpartum group in comparison with that in the other groups. MMP-8 expression was observed in the cervix of rats immediately after parturition, with scattered neutrophils positive for MMP-8 spotted in the stroma of the ripened cervix. MMP-8 expression was not detected in the other groups.
CONCLUSIONRipened cervical fibrous tissue becomes loose and broken, and cervical ripening is accompanied by infiltration of neutrophils from exogenous vessels. These changes are particularly evident after parturition. MMP-2 and MMP-8 cooperate to degrade the cervical fibers, leading to cervical softening and expansion.

Objective To evaluate the relationship between the changes in gray matter volume ( GMV) in different brain regions in the early postoperative period and the development of chronic pain after radical mastectomy. Methods Forty-four American Society of Anesthesiologists physical status Ⅰ or Ⅱpatients, aged 25-64 yr, scheduled for elective radical mastectomy, were divided into 3 groups according to the numeric rating scale ( NRS) score within 3 months after surgery: severe chronic pain group ( NRS score≥3, group SEP), slight chronic pain group (NRS score=1 or 2, group SLP) and no chronic pain group ( NRS score=0, group NP ) . All the patients underwent whole brain MRI scan within 7 days after surgery. MRI data processing and analysis were carried out using SPM8-based VBM software package and REST 1. 8 software. Results There were 17 cases in group SEP, 10 cases in group SLP and 17 cases in group NP. Compared with group NP, GMV in the right postcentral gyrus was significantly decreased, and GMV in the right superior frontal gyrus was increased in group SEP ( P<0. 01) . Conclusion The changes in GMV in the right postcentral and superior frontal gyrus in the early postoperative period may be related to the development of chronic pain after radical mastectomy.
