Objective:To investigate the inhibitory effect and mechanism of different doses of Xiao Chai Hu Tang on C6 glioma cells cultured in vitro. Methods:C6 glioma cells were inoculated in 96 holes,24 holes and 6 holes,each culture plate was divided into 4 groups:control group, low dose group, middle dose group and high dose group, when the cells covered the bottom of culture plate 80%-90%,began adding,cultured for 24 hours after the ter mination of training. Cell proliferation activity,cell viability,protein content and protein positive expression intensity of VEGF and ESM-1,cell apoptosis in early and late stage were detected by CCK-8,in vivo staining,ELISA, immunocytochemistry and flow cytometry. Results: CCK-8 assay showed that the growth of C6 glioma cells was inhibited by low,medium and high dose group;ELISA and immunocytochemistry showed that the expression of VEGF and ESM-1 was lower in the lower, middle and high dose groups, and the levels of protein expression and protein levels were decreased. The flow cytometry showed that the low dose of small radix,middle and high dose group could promote the cell apoptosis. Inverted microscope ob-servation showed that with the increase of dose,the number of cells increased gradually,and the number of dead cells increased,and all kinds of detection methods showed that the inhibition effect increased with dose and dose dependence. The difference between the two groups was statistically significant(P<0. 01). Conclusion:The growth of C6 glioma cells was significantly inhibited by Xiao Chai Hu Tang. It may play a role in inhibiting tumor growth by down regulating ESM-1 and VEGF protein level and promoting cell apoptosis.

BACKGROUND:Previous studies of our research group have confirmed that the texture of porcine reticular dermis at lateral ventral part is softer and has more extensibility than other parts. Therefore, it may serve as the raw material of xenogenic aceluar dermal matrix. However, its comparison with human and rat reticular dermis has not been reported systematicaly in aspects of histomorphology and material characterization. OBJECTIVE:To compare the reticular dermis from the lateral region of porcine abdomen and rat dorsal part with the reticular dermis from human in histology, biomechanics, molecular structure, thermal stability and other properties. METHODS:The reticular dermis samples were taken from adult human, the lateral region of porcine abdomen, the back of rats, for gross observation. Paraffin sections were observed by hematoxylin and eosin staining and sirius red staining under a light microscopy. The relevant data of micrograph were measured by imagine analysis software. These samples were also vacuum-freezing dried and rehydrated, and then their mechanical properties were tested with a electronic tensile machine to calculate the Young’s modulus. Some vacuum-freezing dried samples were powdered and detected by Fourier transform infrared spectrometer and simultaneous thermal analyzer. RESULTS AND CONCLUSION:There were no differences in colagen fiber bundle diameter of the reticular dermis from adult human and the lateral region of porcine abdomen, but the reticular dermis from the back of rats was thinner than that from adult human (P < 0.01). The gap between the reticular layer of the dermis of the lateral region of porcine abdomen was lower than that from adult human (P < 0.0.1); however, there was no difference in the gap between the reticular layers of the dermis of the rat back and adult human (P=0.17). Colagen fibers of porcine reticular dermis were arranged tightly in disorder; the content of type I colagen and ratio of type I/III colagen were higher than those in the reticular dermis from adult human (P < 0.05), but the content of type III colagen was less than that in the reticular dermis from adult human (P < 0.05). Contents of type I and III colagen and their ratio were similar between the reticular dermis of rats and adult human (P > 0.05). There was no significant difference in the Young’s modulus of the three kinds of reticular dermises. Hydrogen bonds involved in the reticular dermal colagen molecules ranged as folows: rats > swine > human. Rat reticular dermis has better thermal stability than that of swine and adult human.

The present study aimed to explore the effects of Eerdun-Wurile on brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF) expressions in the prefrontal cortex of MCAO / R injury rats.Sixty SD male rats of SPF grade were selected to establish the model of MCAO / R with Zea-Longa thread occlusion,and divided into five groups at random:the sham operation group,the model group,the nimodipine group and the Eerdun-Wurile group.After modeling,rats were anesthetized for preparing the brains.The pathomorphological changes of the brains were evaluated by immunohistochemical techniques,such as HE staining and SP.The protein and mRNA expressions of BDNF and NGF in the prefrontal cortex of rats were detected by ELISA and RT-PCR,respectively.As a result,compared with the model group,it was found that the number of necrotic cells in the prefrontal cortex were significantly reduced in the Eerdun-Wurile group (P ＜ 0.05),while the mRNA and protein expressions of BDNF and NGF were significantly increased (P ＜ 0.05).In conclusion,the BDNF and NGF expressions in the prefrontal cortex were up-regulated for stimulating the activation of astrocytes and protecting the neurons with the treatment of Eerdun-Wurile in MCAO / R injured rats,which may be the mechanism of the treatment of Eerdun-Wurile for white vein disease.

Objective To analyze the treatment strategy of the atrial septal defect in the surgical treatment of Ebstein's anomaly combined with the atrial septal defect and the short-term follow-up results of the treatment of Ebstein's anomaly.Methods A retrospective analysis of the clinical data and follow-up results of 20 patients with Ebstein's anomaly and atrial septal defect was conducted from September 2017 to February 2021.And the statistical analysis on the preoperative and postoperative echocardiography results of this group of patients was performed.Results Sixteen patients underwent the biventricular correction surgery,among whom two cases underwent the horizontal atrial tricuspid valvuloplasty(Danielsons procedure),four cases underwent the vertical atrial tricuspid valvuloplasty(Carpentier procedure),and ten cases underwent the conical reconstruction.Two patients were given a half ventricular correction surgery(tricuspid valve reconstruction combined with bidirectional Glenn surgery)and two patients underwent the bidirectional Glenn surgery.The combined atrial septal defects were closed in one stage during extracorporeal circulation for correction of deformitie in 20 patients.At 1,3,6,and 12 months after the surgery,the patient's right ventricular size significantly decreased compared to preoperative(P<0.05),and cardiac function(left ventricular ejection fraction)significantly improved(P<0.05).Conclusion The surgical treatment of Ebstein's anomaly combined with the atrial septal defect should follow the principle of individualized treatment.Biventricular correction is still the first choice for the treatment of Ebstein's anomaly,and the atrial septal defect should be closed at one stage,so as to obtain a good therapeutic effect.

OBJECTIVETo observe sperm motion parameters in pre-freeze and post-thaw semen samples using computer-assisted sperm analysis (CASA) system.

METHODSSemen analyses of 238 samples before freezing and after thawing were separately performed by Hamilton-Thorne Sperm Analyzer.

RESULTSSperm motility in post-thaw samples was significantly decreased. There was significant correlation and difference between pre-freeze and post-thaw samples in sperm motion parameters, including average path velocity (VAP), straight line velocity (VSL), curvilinear velocity (VCL), amplitude of lateral head displacement (ALH), straightness (STR) and linearity (LIN), except heat cross frequency (BCF). The percentage of sperm movement velocity parameters (VAP, VSL and VCL) and moving pattern parameters (ALH) significantly decreased, while that of LIN and STR significantly increased in post-thaw samples.

CONCLUSIONCASA system is of clinically applied value and is a useful tool for evaluating sperm motion parameters in pre-freeze and post-thaw semen samples.

Exocrine ductal carcinoma is an important part of malignant tumors of exocrine glands, including invasive breast ductal carcinoma, salivary duct carcinoma, pancreatic ductal adenocarcinoma and cholangiocarcinoma. Most of these diseases are aggressive, highly malignant and endanger human health. Early detection and diagnosis are the key to a good prognosis for exocrine ductal carcinoma. Different exocrine ductal carcinomas also have certain connections, and their molecular biological characteristics, pathological characteristics and molecular mechanisms have similarities. Surgical resection combined with adjuvant radiotherapy and chemotherapy is currently a common treatment method for exocrine ductal carcinoma. At the same time, its related targeted therapy and immunotherapy sites can also learn from each other. Human epidermal growth factor receptor-2 (HER-2) and the family markers have become breast ductal carcinoma and salivary duct carcinoma targeted therapy sites, and immunotherapy at programmed death ligand 1 (PD-L1) sites has also been involved in many studies, but there is no clear conclusion yet.
