Research status of relationship between schistosomiasis and colorectal cancer

<p>In clinical practice, intestinal mucosal inflammation caused by schistosomiasis has great risks to lead to tumor proliferation and migration of cancer cells. Without timely and effective intervention, chronic schistosomiasis infection induced will further deteriorate into colorectal cancer. On the whole, schistosomiasis once caused serious infection to China. Patients suffering from colorectal cancer who have been infected with schistosomiasis can be diagnosed as schistosomiasis-related colorectal cancer if their preoperative intestinal tract has infection manifestations and postoperative pathology indicates that eggs are deposited near the focus. This paper explores the relationship between schistosomiasis and colorectal cancer by combining relevant data and literature at home and abroad.</p>

Circular RNA (circRNA) and YAP in tumor: A review

<p><strong>Background:</strong> Circular Ribonucleic Acid (circRNA) is a type of RNA that has been found in recent years and is a closed loop structure widely found in eukaryotic cells. <strong>Present situation:</strong> The circRNA is stable in nature, highly conserved and tissue and disease specific, and regulates target gene expression at the transcriptional or posttranscriptional level, which is related to the occurrence and development of tumors. YAP (Yes-associated protein) is the main effector of Hippo signaling pathway. It is found that YAP level is closely related to cell proliferation and apoptosis, tissue organ size control and tumorigenesis. <strong>Aim:</strong> to study the correlation between circRNA and YAP in tumors.</p>

Effect of chloroquine on the apoptosis of tongue squamous cell carcinoma SCC25 cells induced by bleomycin and nedaplatin

<p><strong>Objective:</strong> To study the effect and mechanism of chloroquine-induced chemotherapy drugs bleomycin and nedaplatin on apoptosis of tongue squamous cell carcinoma SCC25 cells. <strong>Methods</strong>: The inhibitory effect of different drugs on the growth of SCC25 cells was screened by MTT assay. MTT, Hoechst33258 staining and FCM were used to observe the changes of morphology, cell cycle and apoptosis of SCC25 cells after different treatments. The quantitative analysis of chloroquine induced by Western blot The effect of chemotherapy drugs on the expression of Bax, Bcl-2 and NFkB apoptosis- related proteins in SCC25 cells. <strong>Results</strong>: The proliferation inhibition rate of bleomycin and nedaplatin SCC25 cells induced by chloroquine was significantly higher than that of bleomycin and nedaplatin alone (p&lt;0.05); Hoechst33358 fluorescence staining and flow cytometry showed In the bleomycin group, the apoptotic rate of the chloroquine plus bleomycin group was significantly increased, and the apoptosis rate of the chloroquine + nedaplatin group was significantly higher than that of the nedaplatin group (p&lt;0.05). The proportion of G0/G1 phase in the chloroquine + bleomycin group was higher than that in the bleomycin group (p&lt;0.05), and the ratio of cells in the S phase to the G2/M phase was decreased; the same chloroquine + nedaplatin group G0/G1 The proportion of cells in the period was higher than that in the nedaplatin group (p&lt;0.05), and the proportion of cells in the S phase and G2/M phase decreased. WB results showed that the expression levels of Bax and NFkB in chloroquine + bleomycin group were significantly higher than those in bleomycin group alone, and the expression level of Bcl-2 was lower than that in bleomycin group alone. Bax and NFkB in chloroquine + nedaplatin group The expression level was significantly higher than that of the nedaplatin group alone. The expression level of Bcl-2 was lower than that of the nedaplatin group alone, and the difference was significant (p&lt;0.05). <strong>Conclusion:</strong> Chloroquine induced bleomycin and nedaplatin can significantly inhibit the proliferation of tongue squamous cell carcinoma SCC25 cells, and its proapoptotic effect may be related to the activation of mitochondrial apoptosis-related proteins and nuclear transcription factors.</p>

Port site hernia: What are the risk factors?

<p><strong>Background &amp; Aim</strong>: The port site hernia is a type of incisional hernia that occurs at port sites after laparoscopic surgery. Various factors have been implicated in the development of port site hernia.</p><p>The aim of this study was to know the risk factors of the port site hernia.</p><p><strong>Patients &amp; Methods:</strong> A retrospective study of patients who underwent different elective laparoscopic procedures in Rizgary Teaching Hospital in Erbil in a period from March 2013 to September 2014.</p><p><strong>Results</strong>: Out of 300 patients only 8 (2.7%) patients developed port site hernia. The time of the hernia occurrence ranged from 3 weeks to six months postoperatively. Half of the hernias were found in cases of age group (60-80) years. Six (75%) of the cases were female patients. All 8 hernias developed after laparoscopic cholecystectomy. Six (75%) hernias developed after open port entrance technique. All hernias occurred when the fascia in 10 mm port was not closed. Seven hernias (87.5%) occurred in patients with BMI ranged (25-34).</p><p><strong>Conclusion:</strong> Age of the patients, technique of entrance, site and size of the port with unclosed fascial layer are important factors for developing port site hernia.</p>

Observation on clinical efficacy of hyperbaric oxygen combined with neurosurgery in treating craniocerebral trauma

<p>The probability of craniocerebral trauma is higher and higher, along with the increasing number of traffic and construction accidents in our lives which cause physical injuries. Main symptoms of such injuries are headache, dizziness, and impairment in language function and limb activity to varying degrees. For patients with severe craniocerebral trauma whose nerve tissue are greatly damaged, there are difficulties in effectively recovering, which may lead to some obstacles in consciousness, intelligence and even action. The current treatment research has found that inappropriate treatment method will increase patients' mortality or disability rate. At present, the effect of hyperbaric oxygen treatment for craniocerebral trauma has been recognized in many clinical trails, seen from increased cure rate.</p>

A Comparative Study of Iranian Smell Identification Test (Iran-SIT) and Single-photon Emission Computed Tomography (SPECT) Results in Discrimination of Anosmia and Malingering in Forensic Cases

<p>Purpose: Olfactory dysfunction is a common complaint following head trauma. Few subjective and objective tests had been proposed for purposes of litigation. Currently, the two most common methodologies for separating malingerers from genuine anosmics are single-photon emission computed tomography (SPECT) and smell identification tests as objective and subjective tests, respectively. The objective of the present study was to compare the efficacy of the SPECT and Iranian Smell Identification Test (Iran-SIT) in discrimination of anosmia and malingering in forensic cases. Method: All of the 16 subjects that fulfilled the requirements completely, underwent both SPECT imaging and Iran-SIT assessment. Results: The sensitivity of SPECT in diagnosing malingering and anosmia was estimated to be 66.6% and 87.5%, respectively. That of Iran-SIT was estimated to be 90% and 75%, respectively. In addition, the sensitivity and specificity of Iran-SIT in diagnosing hyposmia were 100%. Conclusion: Because of the higher sensitivity of Iran-SIT in diagnosing anosmia and higher specificity in diagnosing malingering, it is recommended for directly ruling out the suspicious cases.</p>
