Objective To study and analyze the effects of triple therapy (clarithromycin, amoxicillin, and lansorazole) combined with psychological intervention in the treatment of elderly peptic gastric ulcer. Methods 100 patients with aged gastrointestinal ulcer who were admitted to the hospital from February 2015 to April 2016 were selected as the study subjects, randomly divided into the control group and the experimental group, and 50 patients in each group.The control group was treated with conventional treatment, the experimental group was treated with triple therapy (clarithromycin, amoxicillin, lansorazole) combined with psychological intervention therapy, pay attention to the psychological state of the patients, strengthen the communication and exchanges with the patient, the treatment of patients with increased confidence and treatment compliance. The treatment effect of the experimental group and the control group was compared. Results After the corresponding treatment, the effective rate of treatment in the experimental group was 96.0%, significantly higher than the control group (86.0%), the difference was statistically significant (P<0.05). No obvious adverse reactions were found in the experimental group and the control group. The recurrence rate in the control group was 400%, which was significantly higher than that in the experimental group (14.0%), the difference was statistically significant (P<0.05). Conclusion Triple therapy (clarithromycin, amoxicillin, lansorazole) combined with psychological intervention in treatment of elderly peptic ulcer effect is good, can significantly improve the treatment efficiency, the recurrence rate is low.

OBJECTIVETo examine the association between Ponderal index (PI) at birth and metabolic syndrome during middle age.

METHODSTotally, 975 adults (494 men and 481 women) aged 41-52 from the study cohort of Fetal Origin of Adult Disease were recruited in the study for clinic examinations, involving anthropometry and measurements of blood pressure, fasting and 2 hr plasma levels of glucose and insulin, serum lipid profile. Their HOMA-insulin resistance (IR) index was estimated. Metabolic syndrome (MS) was diagnosed according to 1999 WHO definition. Multivariate logistic regression analysis was used to estimate the effect of PI on MS and the interaction between PI at birth and body mass index (BMI) in adulthood.

RESULTSPrevalence of MS was 18.7% in this mid-aged population, 24.8%, 19.4%, 16.3% and 14.0% in those with less than the 25th percentile, the 25th to less than the 50th percentile, the 50th to less than the 75th percentile and more than 75th percentile of PI at birth, respectively, in a decreasing trend (chi2 M-H for trend=9.938 adjusted for gender, P=0.002). Logistic regression analysis showed that both PI at birth and BMI during adulthood could influence their occurrence of MS (beta=-0.125, P=0.002, for PI; and beta=0.430, P=0.000, for BMI). A synergistic effect between PI at birth and BMI in adulthood was observed in this population. Persons who were thin at birth with PI less than the 25th percentile, and became overweight with BMI greater than or equal to 24 kg/m2 later in their life, were at higher risk of suffering from metabolic syndrome (OR=29.1, 95% CI=13.6-62.1), in comparison with those who became overweight during adulthood from a higher PI at birth (OR=16.0, 95% CI=7.9-32.3) and those who were thin at birth and remained a appropriate BMI during their adulthood (OR=2.0, 95% CI=0.7-5.7). Attributable fraction of the interaction to MS was 34.6%.

CONCLUSIONSThin at birth was a predictor for later occurrence of metabolic syndrome, as well as an effect modifier for the association between of later BMI and metabolic syndrome, i.e., overweight later in his life was most deleterious for a person with growth retardation at birth.

BACKGROUNDThe role of epigenetics in gene expression regulation and development significantly enhances our understanding of carcinogenesis. All the tumor related genes may be the target of epigenetical or genetic regulation. We selected some epigenetically regulated genes for cDNA array analysis and observed variability in the expression of the DICER1 gene in distinct stages of gastric cancer. The aim of this study was to assess the correlation between the expression of DICER1, an epigenetically regulated gene, and gastric cancer.

METHODSTo detect the expression of 506 tumor-associated genes, including DICER1, in the matched cancerous mucosa, pre-malignant lesion (adjacent mucosa), non-cancerous gastric mucosa and distant lymphocyte metastatic lesion in 3 cases of gastric cancers using cDNA array. DICER1 mRNA expression and DICER1 protein expression were further analyzed by Real-time PCR and Western blot in 32 cases of progressive gastric cancer. DICER1 protein expression was also detected in 33 early and 30 progressive gastric cancers by the immunohistochemistry (IHC) method.

RESULTSIn 3 cases of gastric cancer cDNA array showed dramatically decreased expression of DICER1 in pre-malignant lesion, cancerous mucosa and distant lymphocyte metastatic lesions compared with matched noncancerous gastric mucosa, pre-malignant lesion and cancerous mucosa. Real-time PCR results showed that the expression level of DICER1 mRNA in gastric cancer was significantly down-regulated compared to normal gastric tissue (P < 0.05). The IHC assay also showed that the expression of DICER1 was significantly decreased in progressive gastric cancer. Among the 63 cases of gastric cancers, 13/33 early (39.4%) and 19/30 (63.3%) progressive cancers showed negative expression of DICER1 (50.8%). The difference in expression of DICER1 between early and progressive gastric cancers was significant (P < 0.01). The result of Western blotting showed that DICER1 protein was down-regulated significantly in advanced gastric cancer (P < 0.05).

CONCLUSIONSDICER1 expression is decreased during the progression of gastric cancer, especially in progressive gastric cancers, which indicating DICER1 may play an important role in the development of cancer and the epigenetical regulation involved.

OBJECTIVETo study the clinicopathological features and diagnostic criteria of Ewing's sarcoma/primitive neuroectodermal tumor (Ewing's sarcoma/PNET) in oral and maxillofacial region.

METHODSThere were 15 patients with Ewing's sarcoma/PNET in the last 35 years at our hospital, aged 1-49 years and mean 14.5 years. The most common manifestation was swelling of the affected region. The cases were analyzed and histological and immunohistochemical studies were also conducted to examine CD99 (12E7), Vimentin, NSE, S-100, Syn, CD45 (LCA), desmin.

RESULTS(1) The most common histological pattern of Ewing's sarcoma/PNET was a lobular arrangement of uniform, small, hyperchromatic cells in a fibrous background. Some of these tumors were rich in cytoplasmic glycogen. (2) Of the 7 cases, IHC was positive for CD99 (12E7) and Vimentin and negative for lymphoid (CD45), muscle (desmin) markers. S-100 was positive in 4 cases and NSE negative in 3, Syn positive in 1. NSE, S-100, Syn were all negative in 2 cases.

CONCLUSIONSEwing's sarcoma/PNET is more common in teenagers and young people. Immunohistochemistry is essential to distinguish Ewing's sarcoma/PNET from other small round cell tumors. Immunohistochemistry is useful in the diagnosis.

OBJECTIVETo analyse the clinical and pathological characteristics of minor salivary gland tumors.

METHODSA retrospective analysis on 615 cases of intraoral minor salivary gland tumors from 1990-2002 with a confirmed pathologic diagnosis was carried out.

RESULTSIn 615 cases of minor salivary gland tumors, 265 cases were benign, 350 cases malignant. Pleomorphic adenoma was the most common entity and accounted for 81.1% of all benign tumors. Adenoid cystic carcinoma comprised 32.9% of the malignant sample and was the most frequent malignant tumor. The principal location was the palate. Female was a little more of the benign and a male prevalence was observed on the malignant tumor. The mean age of patients with benign and malignant tumors were 40.9 and 49.1 years old, respectively (P < 0.05).

CONCLUSIONWe consider extraordinary manifestation as histopathology, tumor, primary location, age and sex, presenting the results of a review of our experience with those minor salivary gland tumors.

OBJECTIVETo study the expression of P63 in human salivary gland development and the existing of salivary gland stem cells.

METHODS24 embryonic salivary gland samples in different stage, 10 normal salivary gland samples were collected. HE-stained and immunochemistry stain were used.

RESULTSIt could be seen on the HE-stained sections that the epithelial buds proliferated to form the epithelial branches and duct systems, finally the terminal cells differentiated into ductal, myoepithelial and acinous. During the development of salivary gland, the expression of P63 was gradually reduced. In normal adult salivary gland samples, the positive cell interspersed in the basal layer of intercalated duct, secretory duct and excretory duct.

CONCLUSIONP63 plays an important role in human salivary gland development. The result of our experiment shows the distributive characteristic of salivary gland stem cells, which exist abroad in bud stage, but decrease and only exist in the basal layer of ducts in normal adult salivary gland.

OBJECTIVETo investigate the correlation of prolactin receptor (PRL-R) expression to estrogen receptor (ER) and progesterone receptor (PR) expressions in primary breast cancer.

METHODSFor 130 female patients with breast cancer (median age 46 years), PRL-R expression in the primary tumor was detected by immunohistochemistry, and the correlation between PRL-R and ER/PR expressions was analyzed statistically.

RESULTSPRL-R positivity in the primary tumor was found in 89 of the patients (68.5%), and the positivity rate for PRL-R was positively correlated to ER expression (P<0.05). Further stratification of the patients according to the CerbB-2 status revealed such a correlation only in CerbB-2-positive patients (P<0.05). In the patient cohort, no significant correlation was found in the positivity rate between PRL-R and PR expressions (P>0.05), but in CerbB-2-positive patients, the positivity rate of PRL-R showed a positive correlation to PR expression (P<0.05).

CONCLUSIONThe positive correlations in positivity rate between the PRL-R and ER/PR expressions are found only in CerbB-2 positive patients with breast cancer, and the expressional status of CerbB-2 affects the correlation between PRL-R and ER/PR expression in breast cancer.

OBJECTIVETo study the clinicopathologic and immunohistochemical features, biological behavior, diagnosis and treatment of solid pseudopapillary tumor of the pancreas (SPTP).

METHODSA retrospective clinical and clinicopathologic analysis was made on 33 cases of SPTP admitted from May 2001 to 2010 July. There were 7 male and 26 female patients, aging from 13 to 66 years with a mean of 34.3 years.

RESULTSThe tumor was located in pancreatic head of 10 patients, in pancreatic neck of 5 patients, in pancreatic body and tail of 18 patients. Of the 33 patients treated with surgery, 8 underwent simple resection of pancreatic tumor, 6 underwent pancreaticoduodenectomy, 3 underwent tumor resection plus pancreaticojejunostomy, 1 underwent tumor resection plus pancreaticogastrostomy, 11 underwent distal pancreatectomy, 4 underwent distal pancreatectomy plus spleen resection (1 underwent mesohepatectomy for hepatic metastasis). Sixteen of the 33 operations were completed by laparoscopy. Histologically, tumors were composed of papillary and microcystic solid structures, with uniformed population of cells. The pancreas and blood vessels invasion were identified in 3 cases, one of them was combined with liver metastasis, and they are male. Immunohistologically, the tumors were positive for α1-antitrypsin, α1-antichymotrypsin, β-catenin, CD10, CD56 and vimentin (all cases), neuron-specific enolase (3 cases), synaptophysin (6 cases), chromogranin A (4 cases), progesterone receptor (28 cases), estrogen receptor (3 cases), S-100 (6 cases). Totally 33 cases were followed up with a median period of 49 months without tumor recurrence.

CONCLUSIONSSPTP is of low graded malignancy. It primarily affects young women. It may be located in any part of pancreas. Immunohistochemistry is very important for the diagnosis and differential diagnosis of SPTP. Surgical resection is recommended as the treatment of choice. Laparoscopic distal pancreatectomy or tumor resection is feasible and safe for some selected patients, and the prognosis is good.
