Chinese Journal of Clinical and Experimental Pathology 2009;(6):619-623
Purpose To investigate the anti-tumor effect of survivin antisense oligonucleotide (Asodn),and whether it can strengthen the sensitivity of chemical therapy with taxol.Methods The experiment was devided into four groups:control group,liposome group,sense oligonucleotide group,and antisense oligonucleotide group.Survivin antisense oligonucleotide was synthesized,and transfected into gastric cancer cells with liposome.The inhibitory rate of proliferation was tested with MTT,and the expression of survivin protein with Western blot;the morphological changes of apoptosis through Hoechst staining were observed, and the apoptosis rate with flow cytometer.Results As observed through Hoechst staining, the cancer cells had normal blue nucleus in the control group, Lip group, and Sodn group, while in Asodn transfection group the nucleus became condensed, with karyorrhexis. The cell inhibitoty rate in Asodn group increased, presenting in a time-dosage dependence manner; survivin protein expression reduced and apoptotic rate increased; there were differences in statistical significance (P<0.05), as compared with the control group, Lip group and Sodn group. The proliferation-inhibitory rate in Asodn plus taxol group [(78.1±0.8) %] was obviously higher than that in Asodn group [(54.9±1.6)%] and taxol group [(56.7%±0.7)%] (P<0.05).Conclusion Survivin antisense oligonucleotide can inhibit the proliferation of gastric cancer cells, induce apoptosis, and strengthen the effect of taxol on the inhibition of tumor growth.

Purpose:To study the roles of cyclin D1 and cyclin E in non small cell lung cancer(NSCLC) and the relationship between cyclin D1 and cyclin E.Methods:The expression of cyclin D1 and cyclin E in 87 NSCLC were studied immunohistochemically, PCNA was detected immunohistochemically to estimate the proliferative index(PI), the relationship between cyclin D1, cyclin E, PI, clinicopathological and prognostic factors were analysed.Results:Of the 87 NSCLC, 44 8%(39/87) were positive for cyclin D1 and 48.3%(42/87) for cyclin E, the PI of the cyclin D1 positive group was significantly higher than the cyclin D1 negative group( P 〈0.05).Significant differences were shown in the diameter of tumor, lymph node metastasis rate and survival rate between the positive and negative group of cyclin D1( P 〈0.01,0.05,0.01), and there were significant differences in lymph node metastasis, stages and survival rate between the positive and negative group of cyclin E( P 〈0.05,0.05,0.01). The expression of cyclin E in the cyclin D1 positive group was significantly higher than that of the cyclin D1 negative group( P 〈0.05), and the PI, diameter of tumor, lymph node metastasis rate in the coexpression group of cyclin D1 and cyclin E were significantly higher than that of the non coexpression group( P 〈0.05), while the coexpression group had significantly lower survival rate than that of the non coexpression group( P 〈0.05).Conclusions:Cyclin D1 and cyclin E are involved in NSCLC, but their effects are different: cyclin D1 is an important factor in the regulation of proliferation, cyclin E is related to the progression of NSCLC, cyclin D1 can promote the expression of cyclin E, while cyclin E can perhaps intensify the effect of cyclin D1, thus there could exist synergism between cyclin D1 and cyclin E.

Objective:To investigate the LOH at regions on chromosomal arm 8p22,11p15,17p13 and its relationship with clinicopathological parameters. Methods:Thirty-four paraffin-embedded tumor and corresponding noncancerous tissues were analysed. PCR was used to amplified three microsatellite markers D8S136,D11S988 and TP53 located at these chromosomal regions. PCR products were electrophoresed on 6%polyacrylamide gel and detected using silver staining. The P53, c-erBb-2,PR,ER status were determined by immunohistochemistry. Results:Of the three markers we studied, D8S136 was detected LOH at a frequency of 12 in 34 tumors(35.29%). D11S988 and TP53 were detected LOH at a frequency of 5 in 34 tumors(14.71%). There were no obvious associations between LOH at D11S988、TP53 and clinicopathological parameters, but the tumors with LOH at D8S136 were significant larger than that without LOH(P=0.0049). Conclusion: Invasive ductal carcinoma of the breast has a frequent LOH on chromosome 8p22. The loss or inactivation of putative tumor suppressor genes on 8p22 may contribute to the excessive growth of the tumors.

Objective: To observe the clinical efficacy of umbilicus application with Chinese medicine in treating children’s chronic diarrhea due to food intolerance and the value of healthy diet education. Methods:Eighty kids with chronic diarrhea due to food intolerance were recruited from multiple centers and divided by using the random number table into a treatment group of 40 cases and a control group of 40 cases. For both groups, based on the level of serum food-specific immunoglobulin G (Ig-G), the patients were given unified diet following the healthy diet guidance: safe, alternate, and forbidden, while the treatment group was additionally given umbilicus application with Chinese medicine. The therapeutic efficacy and symptom score of traditional Chinese medicine (TCM) were observed and compared respectively after 1-week, 2-week, 4-week, and 12-week treatment. Results:The diarrhea symptoms and coupled symptoms scores dropped significantly in the two groups after treatment ( all P<0.05), and the inter-group comparisons also showed statistical significances (P<0.05). The total effective rate was 97.5% in the treatment group versus 77.5% in the control group, and the inter-group difference was statistically significant (P<0.05). Conclusion:The healthy diet guidance based on the food intolerance test is effective in helping treat diarrhea, while umbilicus application with Chinese medicine works better in treating diarrhea for kids with chronic diarrhea due to food intolerance and can significantly enhance the therapeutic efficacy.

Objective To investigate the prognostic value of right ventricular end-diastolic diameter (RVDD) in patients with chronic systolic heart failure (CHF).Methods A retrospective study was conducted with clinical data of inpatients from 12 third-grade class-A hospitals of Hubei Province between 2000 to 2010,followed up by phone calls.Based on RVDD,patients diagnosed with chronic systolic CHF were divided into four groups:>38 mm,31-38 mm,25-30 mm and <25 mm groups;based on prognosis,patients were divided into the death group and the survival group.Of the death group,patients were further divided into the heart failure death subgroup and the sudden cardiac death subgroup.Single-factor and multi-factor Cox survival analyses were conducted to analyze the relationships between RVDD and mortality,including all-cause mortality,CHF mortality and sudden cardiac death (SCD).Results A total of 16681 patients were enrolled in this study.They were followed up for 1-4 years,during which 6453 died.Multivariate Cox survival analysis showed that the mortality risk for patients with RVDD between 25-30 mm,between 31-38 mm,and >38 mm groups was 1.87,2.41,3.95 times that for patients with RVDD<25 mm,respectively (95%CI:1.64-2.13,2.06-2.80,3.61-4.32,all P<0.01).The risk of sudden cardiac death for patients with RVDD>38mm was 3.82 times that for patients with RVDD<25 mm (95%CI:2.27-5.94,P<0.01).The areas under the ROC curve for death by the best prediction model alone and RVDD combined with the best respectively.RVDD increased the areas under the ROC curve for all cause mortality,CHF mortality and sudden cardiac death.The best prediction model combined with RVDD could discriminate between total mortality,heart failure mortality and sudden cardiac death for patients with different causes of death in multivariate analysis.Conclusions RVDD has a predictive value in the prognosis of patients with chronic systolic heart failure.RVDD increases the sensitivity and specificity of the best prediction model for total mortality prediction in patients with chronic systolic heart failure.RVDD increases the sensitivity and specificity of the best prediction model to discriminate between all-cause mortality,heart failure mortality and sudden cardiac death in patients with different causes of death.RVDD>38 mm can serve as an indicator for the assessment of sudden cardiac death in CHF patients.

AIM: To investigate the effect of sucking porcine liver extracts (LE) and doxorubicin (DXR) on BEL-7402 hepatoma cells in the renal capsulae of BALB/c nude mice. METHODS: Histo-cellular morphology, mitotic counting, ultrastructural observation and in situ DNA labeling apoptotic detection were performed. RESULTS: Both LE and DXR can apparently inhibit the tumors' growth and induce the apotosis of hepatoma cells. LE exerted no apparent effect on the hepatoma cell mitosis, but DXR inhibited it. Electron-microscopic observations showed LE can induce the hepatoma cells to apoptosis. CONCLUSIONS: LE can induce the hepatoma cells to apoptosis, but has no apparent effect of their differentiation and proliferation. DXR can not only induce the hepatoma cells to apoptosis and inhibit their growth, but also can promote their differentiation.

Purpose:
Whether patients suffering liver oligometastases from pancreatic ductal adenocarcinoma (LOPDA) should undergo surgical treatment remains controversial.
Methods:
PubMed and Embase databases were systematically reviewed until 2023 June. Survival data were collected from the Kaplan-Meier curves. Safety and survival were evaluated using primary outcomes such as 1-year, 3-year, and 5-year survival rates, and 30-day mortality and morbidity. A subgroup meta-analysis was conducted to compare survival rates post-synchronous resection and resection post-neoadjuvant chemotherapy in LOPDA.
Results:
Our analysis of 15 studies involving 1,818 patients (surgical group, 648 and nonsurgical group, 1,170) indicates that radical hepatectomy for LOPDA notably improved 1-year (odds ratio [OR], 3.24; 95% confidence interval [CI], 2.45–4.28; P < 0.001), 3-year (OR, 5.74; 95% CI, 3.36–8.90; P < 0.001), and 5-year (OR, 4.89; 95% CI, 2.56–9.35; P < 0.001) overall survival (OS) rates. A separate analysis of 6 studies with 750 patients demonstrated the safety of LOPDA surgery, with no increase in postoperative complications (P = 0.26 for overall morbidity and P = 0.99 for mortality) compared to the patients with no metastatic disease from the pancreatic ductal adenocarcinoma (NMPDA) group. The NMPDA group showed superior 1-year and 3-year OS rates, but not 5-year OS rates compared to the LOPDA group.
Conclusion
Surgical treatment apparently offers a survival advantage to LOPDA by comparing with nonsurgical groups in 1-, 3-, and 5-year OS rates. Radical resection for LOPDA is a safe treatment without more postoperative complications than NMPDA.

Objective To investigate the clinical features and prognosis of antimyelin oligodendrocyte glycoprotein-IgG (MOG-IgG) associated disorders (MOGAD).Methods Eight cases met the diagnostic criteria of MOGAD were reviewed,and the demographics,clinical manifestations,laboratory and imaging results,treatment and prognosis were analyzed. The Expanded Disability Status Scale (EDSS) and the modified Rankin Scale (mRS) were used to dynamically evaluate the neurological disability. Results The ratio of male to female in this 8-case series was 1∶1,the median onset age was 34 years old,and the median disease duration was 42 months. The most common initial symptom is optic neuritis (ON,50%),followed by meningitis and/or encephalitis (25%). Recurrence occurs in 50% of cases,and the recurrence rate of patients with high serum MOG IgG titer (≥1∶32) is 60%. The white blood cells in the cerebrospinal fluid in cases with meningitis/encephalitis or longitudinally extensive myelitis is often>100×10-6/L,which is higher than other phenotypes. There are 6 cases (75%) of patients with different MRI abnormalities,including hypertensity on T-2/Flair image with enhancement at affected optic nerve and orbital tissue,asymptomatic diencephalon/thalamus lesions on T2 and contrasted image,and MRI findings mimic typical multiple sclerosis may also be present. Cases with myelitis can show short-segment eccentric lesions or long-segment central lesions on MRI. Cases with meningitis/encephalitis showed unilateral cortical high T-2/Flair lesions on cranial MRI with various enhancements. After medication and rehabilitation,the peak EDSS of this case series was 5±1.069,and 2.19±1.689 points at the last visit;mRS was 3.25±1.165 points at the peak and 1.25±1.035 points at the last visit. The difference was statistically significant.Conclusions MOGAD is a rare type of demyelinating disease in central nervous with various manifestations,which is highly treatable. Fully understanding of the clinical characteristics,making a early diagnosis through comprehensive tests,and initiating immunization and rehabilitation treatment in time,will contribute to better prognosis for patients.
