Progress in diagnosis and treatment of ovarian metastases in rectal cancer / 中华胃肠外科杂志

Rectal cancer is the most common tumor of digestive tract. For female patients, ovarian metastasis ranks the second place in intraperitoneal organ metastasis. Its symptoms are occult, easily missed and insensitive to systemic treatment, so the prognosis is poor. Surgery is the treatment of choice for patients with rectal ovarian metastases, whether R0 resection is possible or not, and reducing tumor load is associated with better prognosis. With the continuous development of hyperthermic intraperitoneal chemotherapy (HIPEC), tumor reduction can reach the cellular level, which can significantly improve survival. Prophylactic ovariectomy remains a controversial issue in patients at high risk of ovarian metastasis. In this review, we summarize the diagnosis, treatment and prevention strategies of rectal cancer ovarian metastases, hoping to provide some reference for clinical practice.

Breakdown of blood-retinal outer barrier in mice following acute high intraocular pressure / 中华实验眼科杂志

Objective:To investigate the breakdown of blood-retinal outer barrier in the ischemia-reperfusion injury mice following acute intraocular hypertension.Methods:Fifty-seven SPF male C57BL/6J mice were selected and divided into the control group and high-intraocular pressure (IOP) group by using the random number table method.There were 25 mice in the control group and 32 mice in the high-IOP group.After the failure and poor modeling excluded, 20 mice were included in each group, and the left eyes were selected as the experimental eyes.The ischemia-reperfusion injury model of the high-IOP group was established following acute intraocular hypertension by anterior chamber perfusion of 0.9% sodium chloride solution, and the control group only received anterior chamber puncture.Optical coherence tomography was used to detect retinal thickness.Immunofluorescence staining was utilized to identify zonula occludens-1 (ZO-1) protein distribution in retina.Retinal capillary degeneration was identified by trypsin digestion.Inflammatory cell infiltration in retinal sections was observed by hematoxylin and eosin staining.The use and care of the animals complied with the Statement of the Association for Research in Vision and Ophthalmology, and the study protocol was approved by an Ethics Committee of Changsha Aier Eye Hospital (No.2018-KYPJ005).Results:Compared with the control group, the structure of the retinal pigment epithelium (RPE) layer was irregular with obvious exudation and local neuroepithelial detachment and elevation.The thickness of the full retinal layer of mice in the high-IOP group was (235.8±5.3)μm, which was significantly thicker than (213.3±3.9)μm in the control group ( t=3.427, P=0.009). ZO-1 staining results showed that ZO-1 was mainly located in cell membrane and a small part in cytoplasm in the RPE layer of mice.Two days after modeling, ZO-1 in the high-IOP group was significantly internalized with decrease in cell membrane and increase in cytoplasm, and its distribution was irregular.Seven days after modeling, retinal capillary degeneration was observed in the high-IOP group, and the number of degenerated retinal capillaries was 201.0±13.2, which was significantly larger than 11.2±1.7 in the control group ( t=14.280, P<0.01). Hematoxylin-eosin staining results showed that inflammatory cell infiltration, mainly neutrophils, could be observed in the mice retina with high IOP, and the infiltrated inflammatory cells were mainly located under the internal limiting membrane. Conclusions:Acute intraocular hypertension induced retinal ischemia-reperfusion injury in mice destroys the integrity of the outer retinal barriers, and causes granulocyte infiltration in the peripheral circulation, retinal edema as well as retinal capillary degeneration.

Clinical Efficacy of Modified Qilang Prescription in Treatment of Drug-dependent Constipation with Qi and Yin Deficiency and Its Effect on MTL， VIP， 5-HT， and 5-HT4R in Peripheral Blood / 中国实验方剂学杂志

Objective:To investigate the curative efficacy of modified Qilang prescription on drug-dependent constipation with Qi and Yin deficiency and the effects on serum vasoactive intestinal peptide （VIP）， motilin （MTL）， 5-hydroxytryptamine （5-HT）， and 5-hydroxytryptamine 4 receptor （5-HT4R）. Method:A total of 160 patients diagnosed with drug-dependent constipation were randomly divided into a treatment group （<italic>n</italic>=80， Qilang prescription） and a control group （<italic>n</italic>=80， lactulose oral solution）. The treatment lasted for eight weeks. Changes in clinical symptoms， traditional Chinese medicine （TCM） syndrome， and serum VIP， MTL， 5-HT， and 5-HT4R before and after treatment were observed. The clinical efficacies of the two groups were compared. An eight-week follow-up was carried out for the observation of recurrent rate and TCM syndrome. Result:The overall response rate of the treatment group （90.91%） was higher than that （75.00%） of the control group<italic> </italic>（<italic>Z</italic>=-6.514，<italic>P</italic><0.05）. There was no significant difference in serum VIP， MTL， 5-HT， and 5-HT4R between the two groups before treatment. After treatment for eight weeks， both groups showed reduced serum VIP level as compared with those before treatment， and the treatment group was inferior to the control group （<italic>P</italic><0.05）. The serum MTL levels of the two groups were both higher than those before treatment （<italic>P</italic><0.05）， and the treatment group was superior to the control group （<italic>P</italic><0.05）. After treatment， the level of 5-HT in the treatment group was higher than that in the control group （<italic>P</italic><0.05）. The post-treatment 5-HT4R level in the treatment group slightly increased （<italic>P</italic><0.05）， but no significant difference in 5-HT4R levels between the two groups after treatment was observed. During the eight-week follow-up， the recurrence rate in the treatment group was significantly lower than that in the control group at the 2nd and 4th weeks （<italic>P</italic><0.05）. There was no significant difference in the recurrence rate between the treatment group ［57.14% （40/70）］ and the control group ［64.81% （35/54）］ after eight weeks. Conclusion:Modified Qilang prescription was superior to lactulose in the short- and mid-term efficacy on drug-dependent constipation with Qi and Yin deficiency. No significant difference in the long-term efficacy was observed. The underlying therapeutic mechanism might be related to the regulation of serum VIP， MTL， 5-HT， and 5-HT4R levels.

Morphological characteristics associated with rupture risk of multiple intracranial aneurysms

Objective To identify the morphological parameters that are related to intracranial aneurysms (IAs) rupture using a case-control model. Methods A total of 107 patients with multiple IAs and aneurysmal subarachnoid hemorrhage between August 2011 and February 2017 were enrolled in this study. Characteristics of IAs location, shape, neck width, perpendicular height, depth, maximum size, flow angle, parent vessel diameter (PVD), aspect ratio (AR) and size ratio (SR) were evaluated using CT angiography. Multiple logistic regression analysis was used to identify the independent risk factors associated with IAs rupture. Receiver operating characteristic curve analysis was performed on the final model, and the optimal thresholds were obtained. Results IAs located in the internal carotid artery (ICA) was associated with a negative risk of rupture, whereas AR, SR1 (height/PVD) and SR2 (depth/PVD) were associated with increased risk of rupture. When SR was calculated differently, the odds ratio values of these factors were also different. The receiver operating characteristic curve showed that AR, SR1 and SR2 had cut-off values of 1.01, 1.48 and 1.40, respectively. SR3 (maximum size/PVD) was not associated with IAs rupture. Conclusions IAs located in the ICA are associated with a negative risk of rupture, while high AR (>1.01), SR1 (>1.48) or SR2 (>1.40) are risk factors for multiple IAs rupture.

Diagnostic methods for initial evaluation of primary gastrointestinal stromal tumors

To describe the imaging features of gastrointestinal stromal tumors [GISTs] at initial presentation with clinical, surgical, and pathologic correlation, and to evaluate values of various techniques in GISTs. This retrospective study recruited 70 patients with histologically proved GISTs between December 2004, and May 2009 in the Department of General Surgery, Zhongshan Hospital, Fudan Univeristy, Shanghai, China. Each patient underwent CT scanning, 39 patients underwent simultaneous endoscopy, 12 patients underwent endoscopic ultrasound [EUS], and 36 patients underwent transabdominal ultrasonography [TAUS] simultaneously. Features of GISTs were assessed. Computerized tomography findings showed an eccentric mass in 44 patients, an intraluminal component in 24, and a transmural distribution in 2. Forty-two tumors were dumbbell-shaped, 2 were round, while 26 were irregular. Forty-three tumors presented with well-defined masses, while 27 with unclear borders. The arterial phase attenuation showed the continuous enhancement. The portal-venous phase attenuation was heterogeneous in 26 and homogeneous in the other 44. There was a significant correlation between certain CT features and tumor risk stratification. Gastrointestinal stromal tumors were characterized by a smooth shape and normal overlying mucosa in endoscopy, hypoechoic, and solid in TAUS. Imaging examinations are pivotal in the management of GISTs. The CT scan is valuable in the diagnosis, staging, and treatment planning of GISTs. Endoscopy and EUS contribute to the detection of mucosal lesions. Other methods including TAUS, fluorodeoxyglucose positron emission tomography, CT gastrography, and MRI help in specific cases

Compared with GCV, allitridin had stronger inhibitory effect on IE86 expressing, although its efficacy on IE72 was weaker than GCV.</p><p><b>CONCLUSION</b>Allitridin could suppress the expression of IE72 and IE86, especially for IE86 expressing, maybe it is ore of key role in the mechanism of allitridin against HCMV.</p>
