Dexmedetomidine reduced cytokine release during postpartum bleeding-induced multiple organ dysfunction syndrome in rats.

Dexmedetomidine (DEX) is an α 2-adrenergic agonist. It decreases the levels of norepinephrine release, resulting in a reduction of postsynaptic adrenergic activity. In the present study, the effects of DEX on postpartum bleeding-induced multiple organ dysfunction syndrome (BMODS) were studied in rats in which BMODS was induced by the combination of hypotension and clamping of the superior mesenteric artery. We evaluated the role of dexmedetomidine (DEX) in cytokine release during postpartum BMODS in rats. In summary, the present study demonstrated that DEX administration reduced IFN-r and IL-4 release and decreased lung injury during postpartum BMODS. It is possible that DEX administration decreased inflammatory cytokine production in BMODS by inhibiting inflammation and free radical release by leukocytes independent of the DEX dose.

Auxiliary diagnostic value of D2-40 in early lung adenocarcinoma and precursor lesions.

AIMS: Objective to investigate whether D2-40 can be used as a marker of early lung adenocarcinoma and precursor lesions. METHODS: In order to explore the value of D2-40, a monoclonal antibody that recognises the podoplanin, as an auxiliary diagnostic marker to aid the diagnosis of these conditions, we performed the immunohistochemical (IHC) staining using early lung adenocarcinoma, infiltrating adenocarcinoma, benign lung lesions and relevant peritumour normal tissues. The microscopic examination was performed to analyse the D2-40 IHC staining. RESULTS: We found that there was no D2-40 staining in 47 cases of early stage lung adenocarcinoma and precursor lesions; only 1 of the 32 cases (3.13%) of infiltrating adenocarcinoma stained positive. There was 100% D2-40 staining in 30 cases of benign lung lesions and 79 cases of peritumour normal tissues. The positivity rate in carcinoma group was 1.27% and the normal tissue group was 100%, (p<0.01). Based on our findings, we concluded that D2-40 IHC staining in lung adenocarcinoma and precursor lesions compared with normal alveolar epithelia displayed the 'none or all' phenomenon. CONCLUSIONS: The results from our study suggested that D2-40 can be sued as auxiliary diagnostic tool in early lung adenocarcinoma and its precursor lesions.

Giant extralobar pulmonary sequestration with severe pleural effusion in neonatal period: A case report / 中国胸心血管外科临床杂志

@#Giant extralobar pulmonary sequestration in newborns is still relatively rare in pulmonary diseases, and there are few relevant studies published. A neonate with the giant extralobar pulmonary sequestration accompanied by severe pleural effusion was reported here. After 12 days of birth, the diseased lung tissue was surgically extracted. The patient had an uneventful postoperative recovery and was discharged from the hospital. The case shows the advantage of early surgical treatment to extralobar pulmonary sequestration with severe pleural effusion in neonatal period.

Clinical Value of Platelet and Its Parameters Combined with Tumor Markers in Preoperative Differentiation of Hepatocellular Carcinoma and Intrahepatic Cholangiocarcinoma / 肿瘤防治研究

Objective To evaluate the value of PLT and its parameters combined with AFP, CA199, CA125 and CEA on the preoperative differential diagnosis of hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (ICC). Methods We analyzed retrospectively 274 patients with liver cancer who underwent surgery in the Second Hospital of Lanzhou University. They were divided into 229 cases in HCC group and 45 cases in ICC group according to postoperative pathological results. The differences of PLT, its parameters and tumor markers between the two groups were compared. ROC curve was used to evaluate the differential diagnosis effect on HCC and ICC by significantly different indicators in single and combined forms. The best scheme was verified in the patients with determined and undetermined preoperative diagnosis. Results Compared with HCC group, the levels of PLT, PCT, CA199 and CA125 in ICC group were higher (P < 0.05) and the level of AFP was lower (P < 0.05). The diagnostic analysis results of ROC curve showed that in single test, the AUC of AFP for HCC diagnosis was the largest (0.827). The AUC of the combined groups was higher than the single groups of tumor markers; the AUC of the PCT+AFP+CA199+CA125 group was the highest in all combination groups, and AUC was 0.891. The verification of the best combination group showed that the AUC was 0.924 in the preoperative determined diagnosis group and 0.854 in the undetermined diagnosis group. Conclusion Tumor markers in combination with PLT and PCT can increase the preoperative differential diagnosis efficacy of HCC and ICC. The combination of PCT, AFP, CA199 and CA125 before operation is helpful to further determine the diagnosis and plan the operation scheme.

Clinicopathological analysis and literature review of Burkitt-like lymphoma with 11q aberration / 中国综合临床

Objective:To investigate the clinicopathological features,differential diagnosis,treatment and prognosis of Burkitt-like lymphoma with 11q aberration (BLL-11q).Methods:The clinical manifestations,histological morphology,immunophenotype and molecular genetic changes of 2 cases of BLL-11q admitted to the department of pathology of The First People's Hospital of Lianyungang in 2020 and 2021 were analyzed retrospectively,and the relevant literatures were reviewed.Results:Patients were found with right neck masses inadvertently and grew rapidly. They presented with localized disease with Ann Arbor stages IA and IIA. Microscopically, the normal structure of the lymph node disappeared and was replaced by a diffuse proliferation of lymphocytes, with consistent morphology and medium size. And the presence of "star-sky" phenomenon was obvious, the morphological characteristics were similar to Burkitt lymphoma. Immunophenotypically, tumor cells were diffusely positive for CD20, CD79α, PAX5, CD10 and Bcl-6, partly moderately positive for C-MYC and MUM-1, however, CD3, Bcl-2, CD30 and TDT were negative,Ki-67 positive index was more than 95%, and EBER was negative. FISH detection showed that MYC, Bcl-2, and Bcl-6 were negative. Both cases had the 11q23.3 gain and 11q24.3 loss. Both patients were treated with chemotherapy and followed up for 10-22 months,and achieved complete remission and disease-free survival.Conclusion:BLL-11q is a rare germinal center B-cell lymphoma with abnormal long arm of chromosome 11 and lack of MYC gene rearrangement. It should be distinguished from Burkitt lymphoma, diffuse large B-cell lymphoma, B-lymphoblastic lymphoma, large B-cell lymphoma with IRF4 rearrangement and high-grade B-cell lymphoma. On the basis of morphology and immunophenotype, the diagnosis depends on genetic detection. There may be a better prognosis.

Analysis of the efficacy and related influencing factors of pelvic packing in the treatment of intractable postpartum hemorrhage after emergency perinatal hysterectomy / 中华妇产科杂志

Objective:To investigate the effect of pelvic packing on the control of intractable postpartum hemorrhage after emergency perinatal hysterectomy (EPH).Methods:Eleven cases with complete clinical data of pelvic packing due to failure of hemostasis after EPH were collected to evaluate the outcome, complications, hospital stay of pregnant women, and to analyze the factors affecting the effect of pelvic packing. The cases included patients who were admitted to the Third Affiliated Hospital of Guangzhou Medical University after pelvic packing treatment in the other hospital due to continuous bleeding after EPH or who were referred to our hospital for pelvic packing treatment due to continuous bleeding after EPH from January 2014 to August 2021.Results:The median gestational week of 11 pregnant women was 38.3 weeks(38.0-39.9 weeks) , and the methods of termination of pregnancy were cesarean section in 7 cases (7/11) and vaginal delivery in 4 cases (4/11). The median time between postpartum hemorrhage and pelvic tamponade was 10 hours (5-57 hours), the median amount of bleeding was 8 500 ml(4 800-15 600 ml) , the median number of pelvic tamponade was 3 pieces (2-7 pieces), and the median retention time of gauze pad was 6.0 days (3.0-6.0 days). The median frequency of laparotomy in this pregnancy was 3 times (2-3 times), with a maximum of 4 among the 11 cases, the first pelvic packing was successful in hemostasis in 9 cases, and the final successful treatment in all of the 11 cases. All parturients had hemorrhagic shock (11/11) and disseminated intravascular coagulation (11/11) before pelvic packing. Other common complications were multiple organ dysfunction syndrome (9/11), cardiac arrest (4/11), deep vein thrombosis (3/11), septic shock (3/11), and intestinal obstruction (1/11). All parturients took out the gauze after the coagulation function returned to normal and there was no active bleeding. The recovery time of coagulation function in 11 cases was 3 days (3-5 days), the retention time of gauze pad was 6 days (3-6 days), the median length of stay in intensive care unit was 14 days (11-26 days), and the median total length of stay was 22 days (16-49 days).Conclusions:Pelvic packing could be used as a temporary strategy for intractable postpartum hemorrhage after EPH, which provides a key time for injury control resuscitation for patients with unstable vital signs. This technology provides an opportunity for referral to superior medical institutions and further treatment.

Only 1 patient was completely relieved after operation, and most patients needed combined treatment to control the disease.Conclusions:Mixed thyrotropin and growth hormone secreting adenoma is the most common type of the disease, the clinical manifestations are complex, and the tumor is aggressive growth, surgical treatment can not be completely relieved and radiotherapy and/or combination of medicine treatment can help to improve the condition.

Research Progress of Pulmonary Epithelioid Hemangioendothelioma / 中国肺癌杂志

Epithelioid hemangioendothelioma (EHE) is a rare vascular neoplasm that develops from vascular endothelial cells. It has been reported to occur many sites of body, but the most common EHE presentations are soft tissue (limbs), bone, liver and lung. Compared with other pulmonary tumors, pulmonary epithelioid hemangioendothelioma (P-EHE) is relatively rare. According to a literature review, more than 100 cases have been described all over the world. Due to the low incidence of P-EHE, lack of specificity in clinical symptoms and radiological findings, it is often misdiagnosed. Meanwhile, many patients do not receive appropriate treatment, resulting in poor prognosis in some cases. Histology and immunohistochemical methods are essential for diagnosis. However, there is no established standard treatment for P-EHE, because of the rarity of the disease. When the lesions are small and limited in number, surgical is the best treatment, achieving the purpose of diagnosis and treatment at the same time. This article tries to present the etiopathogenesis, clinical manifestations, diagnosis, treatment and prognosis of P-EHE.

To evaluate the expression of cAMP-dependent protein kinase type I-alpha regulatory subunit (PRKAR1α) in non-small cell lung cancer (NSCLC) and its correlation with clinicopathological features.
 Methods: PRKAR1α expressions in 79 NSCLC patients and matched adjacent non-carcinoma tissues were analyzed by using qRT-PCR and immunohistochemistry.
 Results: The negative rates of PRKAR1α protein in NSCLC, lung squamous cell carcinoma (SCL) and lung adenocarcinoma (ACL) were 58.2%, 77.8%, 32.4%, respectively. Compared to the matched adjacent non-carcinoma tissues, there were significant differences in levels of PRKAR1α mRNA and protein in ACL (P0.05). The expression of PRKAR1α protein was positively correlated with histological type, TNM stage, and lymph node metastasis (P0.05).
 Conclusion: Low expression of PRKAR1α in ACL might be involved in the pathogenesis, which might serve as a novel diagnostic candidate.

Intravascular ultrasound-guided interventional treatment of coronary true bifurcation lesions:a clinical ;study / 介入放射学杂志

Objective To investigate the application of intravascular ultrasonography in guiding the performance of interventional management for coronary true bifurcation lesions. Methods A total of 62 patients with coronary true bifurcation lesions, who were admitted to authors’ hospital during the period from April 2010 to Jan. 2014 to receive double stenting treatment, were included in this study. The patients were randomly divided into intravascular ultrasonography group (IVUS group, n=32) and coronary angiography group(CA group, n=30). The minimal lumen diameter(MLD), the minimal lumen area(MLA), the reference lumen diameter (RLD), the length of the lesion and the diameter and length of the implanted stent were determined, and the results were compared between the two groups. During the follow-up period lasting for 12 months after percutaneous coronary intervention, the incidence of in - stent thrombus, target lesion revascularization (TLR) and major adverse cardiac events were recorded. Results The MLD values of the main artery and branches in IVUS group were higher than those in CA group, but the difference was not significant (P>0.05). The MLA, RLD, the diameter and length of the implanted stent in IVUS group were significantly larger than those in CA group (P0.05). Conclusion Intravascular ultrasound- guided double stent implantation for coronary true bifurcation lesions can help optimize the performance of stenting and improve the long-term outcome of percutaneous coronary intervention.

Diagnostic utility of immunohistochemical markers SALL4, D2-40 and Glypican-3 in primary testicular germ cell tumors / 临床与实验病理学杂志

Purpose To investigate the diagnostic utility of the immunohistochemical markers SALL4, D2-40 and Glypican-3 in prima-ry testicular germ cell tumors (TGCTs). Methods The expression of SALL4, D2-40 and Glypican-3 protein was detected by EnVi-sion immunohistochemical method in 56 cases of primary testicular germ cell tumors, including 5 intratubular germ cell neoplasms ( IT-GCNs) , 10 seminomas, 14 embryonal carcinomas ( ECs) , 14 yolk sac tumors ( YSTs) , 1 choriocarcinoma, 5 immature teratomas and 12 mature teratomas. 10 normal testicular tissues and 5 lymphomas were selected as control. Results All of ITGCNs, seminomas, YSTs and ECs were diffusely strongly positive for SALL4. Focal SALL4 staining was seen in choriocarcinoma, 3 of 5 immature terato-mas and 3 of 12 mature teratomas. All of ITGCNs, seminomas showed diffusely strong D2-40 staining. ECs (4/14) were focally posi-tive for D2-40, while choriocarcinoma, YSTs and teratomas were negative for D2-40. Glypican-3 was diffusely positive in YSTs (13/14), and focally weakly positive in ECs (2/14), respectively. ITGCNs, seminomas, choriocarcinoma and teratoma were negative for Glypican-3. In contrast, 10 normal testicular tissues and 5 lymphomas showed no SALL4, D2-40 and Glypican-3 staining. Conclu-sions SALL4 is a useful diagnostic marker with high sensitivity and specificity for TGCTs. Combination of SALL4, D2-40 and Glypi-can-3 is helpful to the diagnosis and differential diagnosis for TGCTs.
