The main treatment strategies for chronic pancreatitis in young patients include therapeutic endoscopic retrograde cholangio-pancreatography (ERCP) intervention and surgical intervention. Therapeutic ERCP intervention is performed much more extensively for its minimally invasive nature, but a part of patients are referred to surgery at last. Historical and follow-up data of 21 young patients with chronic pancreatitis undergoing duodenum-preserving total pancreatic head resection were analyzed to evaluate the outcomes of therapeutic ERCP intervention and surgical intervention in this study. The surgical complications of repeated therapeutic ERCP intervention and surgical intervention were 38% and 19% respectively. During the first therapeutic ERCP intervention to surgical intervention, 2 patients developed diabetes, 5 patients developed steatorrhea, and 5 patients developed pancreatic type B pain. During the follow-up of surgical intervention, 1 new case of diabetes occurred, 1 case of steatorrhea recovered, and 4 cases of pancreatic type B pain were completely relieved. In a part of young patients with chronic pancreatitis, surgical intervention was more effective than therapeutic ERCP intervention on delaying the progression of the disease and relieving the symptoms.

OBJECTIVETo explore the correlation between the expressions of hypoxia inducible factor-1α (HIF-1α) and insulin in pancreatic cancer.

METHODSHIF-1α and insulin expression was detected by immunohistochemistry in the center and the edge of pancreatic adenocarcinoma specimens of 65 cases. Western blot was used to detect HIF-1α expression and insulin level in the center and the edge of pancreatic adenocarcinoma specimens of 28 cases. The relationship between HIF-1α expression and insulin level in the pancreatic cancer was analyzed.

RESULTSThe results of immunohistochemistry and Western blot showed that HIF-1α protein expression was high in both the center and the edge of pancreatic cancers (P > 0.05), and insulin level was significantly higher at the edge of specimen than that in the center (P < 0.05). HIF-1α protein and insulin levels were positively correlated at the edge of cancer tissue (r = 0.374, P < 0.05), but no significant correlation between them in the center of cancerous tissue (r = -0.145, P > 0.05).

CONCLUSIONInsulin may promote the local invasion and metastasis of pancreatic cancer by up-regulating HIF-1α.

OBJECTIVEEosinophilic airway inflammation is one of the basic characteristics of allergic asthma. Toll-like receptor is one of the most important innate immunity pattern recognition receptors. Glucocorticoids (GCS) are still the most effective treatment for asthma. However, few reports of studies on regulatory mechanism of GCS on the innate immunity system are available. The mechanism of effects of GCS on TLR4 is unclear. The present study aimed at understanding the effect of dexamethasone (DXM) on change of TLR4 and mechanism of regulatory effect of TLR4 on eosinophil (EOS) apoptosis.

METHODSTwenty-seven Sprague-Dawley (SD) rats (age 28 to 42 days, body weight 120 to 180 gram) were randomly divided into the control group, asthma group and DXM group with 9 in each. Asthma model rats were sensitized with the mixture of ovalbumin (OVA, 1 mg) and Al (OH)(3), 100 mg on day 1 and day 8, repeatedly exposed to aerosolized OVA after day 15, once a day for three days and continued for 30 minutes at every time. During the sensitization stage, 100 microg/ml DXM were prepared with DXM group for every other day, and the same doses DXM were prepared for every day on the stage of challenge. The histopathological changes of lung tissues were observed with light microscope (LM). EOS and other inflammatory cells in bronchoalveolar lavage fluid (BALF) were counted; the concentrations of OVA-sIgE in serum were measured by using "sandwich" ELISA; The expressions of TLR4 mRNA were determined by in situ hybridization, the apoptosis of EOS was detected by TUNEL.

RESULTS(1) LM showed many inflammatory cells infiltration around the bronchi and blood vessels, bronchus mucus increased, airway epithelium damage and desquamation, and airway mucous plugs in asthma group, whereas DXM group showed significantly milder changes. (2) Inflammationary cells count in BALF of asthma group was significantly higher as compared to control group (P < 0.01); compared with asthma group, the total cell count, EOS absolute count and EOS% were all significantly decreased in DXM group [(2.14 +/- 0.10) x 10(9)/L, (4.78 +/- 1.23) x 10(7)/L, (2.17 +/- 0.25)%]. (3) Levels of OVA-sIgE in serum of asthma group [(83.40 +/- 6.80) microg/ml] were significantly higher than those of the control group [(14.38 +/- 4.25) microg/ml] (P < 0.01), while those of DXM group [(45.02 +/- 7.47) microg/ml] were significantly lower than asthma group (P < 0.0 1). (4) There were no significant differences in TLR4 mRNA detected by in situ hybridization between control group (24.71 +/- 0.85) and asthma group (25.81 +/- 3.56) (P > 0.05); but it significantly increased in DXM group (29.86 +/- 3.92) as compared to asthma group. (5) The percentages of apoptotic EOS in asthma group [(7.39 +/- 1.93)%] were significantly lower than those in control group [(9.06 +/- 1.52)%] (P < 0.01); and significantly higher in DXM group [(13.33 +/- 1.09)%] than in asthma group (P < 0.01). There were significantly positive correlations between TLR4 mRNA and the percentage of apoptotic EOS (r = 0.612, P < 0.01).

CONCLUSIONDXM can decrease OVA-sIgE level, induce EOS apoptosis, which may correlate with the activation of TLR4 signal transduction.

Sodium glucose co-transporter 2 (SGLT-2) inhibitors are newly developed but promising medicine for type 2 diabetes. However, patients with a different renal threshold for glucose excretion (RT(G)) may have a different reaction to this medicine. Therefore, the objective of this study was to investigate the characteristics of RT(G) and its impact factors in patients with type 2 diabetes mellitus (T2DM). The clinical and laboratory data of 36 healthy individuals and 168 in-hospital patients with T2DM were collected and analyzed, RTG was calculated using blood glucose (BG) measured by dynamic BG monitoring, urinary glucose excretion (UGE) and estimated glomerular filtration rate (eGFR). The characteristics of RT(G) were investigated. The risk factors for high RT(G) were analyzed using non-conditional logistic regression analysis. Our results found that RT(G) of the T2DM group was higher than that of the healthy individuals (P < 0.05); and 22.22% from the healthy individuals group but 58.33% from the T2DM group had high RT(G). Age, duration of diabetes, body mass index (BMI), and homeostasis model assessment insulin resistance index (HOMA-IR) were independently associated with high RT(G) (P < 0.05). Further stratified analysis revealed that RT(G) in T2DM patients increased with age, duration of diabetes, and BMI. In conclusion, RT(G) is increased in patients with T2DM, especially in those with longer diabetic duration, higher BMI, and those who are older. Therefore, these patients may be more sensitive to SGLT-2 inhibitors.

To compare the clinical outcome of autologous peripheral blood stem cell transplantation (APBSCT) and autologous bone marrow transplantation (ABMT) in treatment of patients with acute leukemia in first remission, 41 patients received APBSCT, 17 patients received unpurged ABMT and 30 patients received purged ABMT. The results showed that hematopoietic recovery was significantly earlier after APBSCT than that after purged or unpurged ABMT. The 3-year disease-free survival (DFS), relapse rate (RR) and transplant-related mortality (TRM) for all patients of 3 groups were 51.7%, 41.7% and 6.8%, respectively. DFS and RR were significantly influenced by disease types (ALL or AML) and intervals between diagnosis and CR(1) or CR(1) and transplant. The main causes of transplant-related death were infection and hemorrhage. After APBSCT, DFS, RR and TRM were 48.4%, 43.9% and 4.9%, respectively, and did not differ significantly from those found in unpurged ABMT (47.1%, 45.6% and 11.8%) or purged ABMT (66.5%, 29.6% and 6.7%). It is concluded that the clinical outcome of APBSCT is similar to unpurged or purged ABMT but APBSCT allows faster recovery of hematopoiesis and needs less transfusion support.

The purpose of this study was to investigate the etiology, pathological characteristics, management and prognosis of chronic pancreatitis in the Chinese population. The clinical data of 142 patients with chronic pancreatitis were retrospectively studied. All patients were of Chinese nationality and hospitalized from January 2008 to December 2011. Their ages ranged from 14 to 76 years, with a mean of 43 years. Of 142 patients, there were 72 cases of obstructive chronic pancreatitis (50.70%), 19 cases of alcoholic chronic pancreatitis (13.38%), 14 cases of autoimmune pancreatitis (9.86%) and 37 cases of undetermined etiology (26.06%). Pathologically, the average inflammatory mass diameter was 3.8 ± 3.3 cm, biliary obstruction occurred in 36 cases, gall stones in 70 cases, calcification in 88 cases, ductal dilatation in 61 cases, side branch dilatation in 32 cases, ductal irregularity in 10 cases, lymphocytic inflammation in 23 cases, obliterative phlebitis in 14 cases, extra pancreatic lesion in 19 cases and fibrosis in 142 cases. Location of pancreatic lesion in the region of head (n=97), neck (n=16), body (n=12), tail (n=15) and whole pancreas (n=2) influenced the choice of surgical procedures. Ninety-four patients (66.20%) received surgical treatment and 33.80% received other treatments. After operation, 80.85% of 94 patients experienced decreased pain, and 8.51% of 94 showed recovery of endocrine function but with a complication rate of 12.77%. All the operations were performed successfully. According to the pain scale of European Organization for Research and Treatment of Cancer (QLQ-C30) a decrease from 76 ± 22 to 14 ± 18 was observed. Etiology, pathological characteristics, management and prognosis of chronic pancreatitis in the Chinese population vary from others.

Objective To investigate the predictive values of platelet to lymphocyte ratio (PLR) and neutrophil to lymphocyte ratio (NLR)before percutaneous coronary intervention (PCI)and a reexamination of coronary angiography (CAG)on the development of in-stent restenosis (ISR)in patients implanted with coronary drug eluting stent (DES).Methods For this study we enrolled 123 patients who had undergone successful drug eluting stent implantation (SI)and a further CAG reexamination.Another 45 patients with non-coronary heart disease (NC)served as controls.PLR and NLR were measured before DES implantation or CAG and compared between the groups.Patients in SI group were further divided into two subgroups based on the results of CAG reexamination:ISR group and no-ISR group.Hematologic data were reexamined before further CAG and compared between the subgroups.Receiver operator characteristic curve (ROC)was drawn to evaluate the predictive values of PLR and NLR for ISR.Results PLR and NLR before PCI or a further CAG were significantly higher in ISR group (34 patients)than in non-ISR group (89 patients,P＜0.05).Before PCI,the best cutoff value of PLR in screening restenosis was 107.20;the sensitivity and the specificity were 64.7% and 65.2%.The best cutoff value of NLR in screening restenosis was 2.72; the sensitivity and the specificity were 61.8% and 70.8%. Before CAG reexamination,the best cutoff value of PLR in screening restenosis was 160.08;the sensitivity and the specificity were 26.5% and 97.8%.The best cutoff value of NLR in screening restenosis was 2.08;the sensitivity and the specificity were 73.5% and 56.2%.Conclusion Both PLR and NLR before PCI or CAG reexamination can be predictors of ISR in patients implanted with DES.

Individual identification by measuring the human skeleton is an important research in the field of forensic anthropology. Computed tomography （CT） technology can provide high-resolution image of skeleton. Skeleton image can be reformed by software in the post-processing workstation. Different skeleton measurement indexes of anthropology, such as diameter, angle, area and volume, can be measured on section and reformative images. Measurement process is barely affected by human factors. This paper reviews the literatures at home and abroad about the application of measuring skeleton by CT in forensic anthropology research for individual identification in four aspects, including sex determination, height infer, facial soft tissue thickness measurement and age estimation. The major technology and the application of CT in forensic anthropology research are compared and discussed, respectively.
