ABSTRACT

OBJECTIVE@#To investigate the clinicopathological features of intestinal diffuse large B-cell lymphoma (DLBCL).@*METHODS@#The clinical features, pathological morphology, immunophenotype, and EBER in situ hybridization of 136 DLBCL patients diagnosed in Jinan People's Hospital Affiliated to Shandong First Medical University from January 2007 to October 2014 were analyzed retrospectively. A total of 136 DLBCL samples were obtained, the DLBCL sites were categorized as: duodenum (n=23), ileocecal region (n=63), other small intestine (n=29), rectum (n=7), and other large intestine (n=14). Survival curves for the DLBCL patients were plotted using the Kaplan-Meier method and judged by the Log-rank test.@*RESULTS@#Patients with DLBCL of the ileocecal region and other small intestine except duodenum were mainly male (P=0.042), and had a higher proportion of limited-stage tumors(P=0.015), and lower International Prognostic Index (IPI) (P=0.001). Patients with DLBCL of ileocecal region had higher incidence of lactate dehydrogenase elevation (P=0.007), and higher incidence of intestinal obstruction or perforation (P<0.001) than those with DLBCL of other regions. The 5-year overall survival and 5-year progression-free survival of patients with DLBCL in ileocecal and other small intestine sites were higher than those in other sites, but the differences were not statistically significant (P=0.135, 0.459). Fifty percent of intestinal DLBCL were germinal center B cell-like (GCB) subtypes. A low-grade B-cell lymphoma was found in 21% of 136 tumor samples. In ileocecal and other small intestinal specimens, the proportion of low-grade B-cell lymphoma was 29%, and the difference was statistically significant(P=0.025). About 16% of 136 DLBCL samples expressed follicular lymphoma while no mucosa-associated lymphoid tissue lymphoma . The Epstein-Barr virus-encoded RNA-1 (EBER1) positive rate of duodenal DLBCL was significantly higher than that of other sites (5/23, 22% vs 2/63, 3%, P=0.001).@*CONCLUSION@#The intestinal DLBCL is commonly observed in male, and ileocecal is the most primary site. Patients with DLBCL of the ileocecal region and small intestine except duodenum have low IPI, high proportion of limited-stage tumors, low level of lactate dehydrogenase, high incidence of intestinal obstruction or perforation, and low incidence of inert lymphoma. The EBER1 positive rate of DLBCL in duodenal is higher.

ABSTRACT

Objective: To explore the efficacy of mild moxibustion plus loratadine tablets for children with allergic rhinitis (AR).Methods: A total of 80 children were randomized into a control group and an observation group, with 40 cases in each group. The control group was treated with loratadine tablets, and the observation group was treated with mild moxibustion plus loratadine tablets. Before and after treatment, the total nasal symptom score (TNSS) was evaluated, and the serum eosinophils (EOS) count, and the interleukin (IL)-27 and macrophage migration inhibitory factor (MIF) levels were measured. Clinical efficacy was evaluated after treatment. Results: The total effective rate of the observation group was higher than that of the control group (P<0.05). After treatment, the TNSS in both groups decreased (P<0.05), and the TNSS in the observation group was lower than that in the control group (P<0.05); the serum EOS count in both groups decreased (P<0.05), and the serum EOS count in the observation group was lower than that in the control group (P<0.05). The serum IL-27 level in the control group had no statistical difference compared with the same group before treatment (P>0.05), and the serum MIF level decreased after treatment (P<0.05). The serum IL-27 level in the observation group increased after treatment (P<0.05), and the serum MIF level decreased after treatment (P<0.05), and were both statistically different from those in the control group (P<0.05). Conclusion: Mild moxibustion plus loratadine tablets is effective in treating children with AR. It can significantly improve the nasal symptoms and reduce the serum EOS count, which may be related to the regulation of the serum IL-27 and MIF levels.

ABSTRACT

Objective::The effects of three different doses of borneol on acute myocardial infarction (AMI) model rats and the effects on oxidative stress factors were compared to provide reference for elucidation of the dose-effect relationship and mechanism of anti-myocardial infarction. Method::Healthy adult male SPF SD rats were randomly divided into sham operation group, model group, solvation model group, nitroglycerin group, Borneolum high, medium and low dose(0.6, 0.3, 0.15 g·kg-1) group, l-Borneolum and Borneolum syntheticum high, medium, low dose(0.2, 0.1, 0.05 g·kg-1) group, a total of 13 groups, 20 in each group. Gavage was performed at 20 mL·kg-1 once a day for 3 days of continuous preventive administration. The sham operation group and the model group were given the same volume of distilled water, and the solvation model group was given the same volume of 5% polysorbate 80.On the third day of the pre-administration, 30 minutes after the last dose, the left anterior descending coronary artery was ligated to make a model, and the successful rats were treated for 3 days. BL-420N biological system analyzer was used to record the ST-segment amplitude and hemodynamic changes. Rat body weight and cardiac weight were weighed to calculate cardiac viscera coefficients, 2, 3, 5-triphenyl tetrazolium chloride (TTC) staining was used to calculate the myocardial infarction rate. Hematoxylin-eosin (HE) staining was used to evaluate the degree of myocardial pathological damage. According to the kit requirements, serum levels of lactate dehydrogenase (LDH), aspartate amino-transaminase (AST), creatine kinase isoenzyme (CK-MB) and oxidative stress factors superoxide dismutase (SOD), malondialdehyde (MDA) were detected. Result::Compared with the sham operation group, the ST segment amplitude of the model group significantly increased after 5 minutes, the left ventricular diastolic blood pressure (LVDP) value increased significantly, and the measured maximum shortening velocity (Vpm) value of the left ventricular myocardial contraction component significantly decreased. The organ coefficient and myocardial infarction rate were extremely significantly increased, and the myocardial pathological tissue was severely damaged. The serum CK-MB, AST, LDH, and MDA contents were significantly increased (P<0.05, P<0.01). Compared with the solvation model group, the Borneolum and l-Borneolum in the middle and low, and the Borneolum syntheticum high dose groups could significantly inhibited the abnormal elevation of ST segments at different time points. The Borneolum and l-Borneolum high, medium, low, and Borneolum syntheticum high dose groups significantly increased the left ventricular systolic blood pressure (LVSP) value and decrease the LVDP value (P<0.01). The Borneolum medium, low, and l-Borneolum high, medium, Borneolum syntheticum high dose groups significantly increased the maximum rate of left ventricular pressure rise (dp/dt max) and Vpm value (P<0.05, P<0.01). The Borneolum and l-Borneolum medium, low dose groups significantly reduced rat cardiac organ coefficients. The Borneolum high, medium, low and l-Borneolum, Borneolum syntheticum medium, low dose groups significantly improved myocardial infarction in rats (P< 0.05, P<0.01). The Borneolum low, l-Borneolum high, medium, and Borneolum syntheticum high groups also significantly improved the degree of pathological damage (P<0.01). High dose of l-Borneolum significantly reduced CK-MB content, medium and low dose of l-Borneolum significantly reduced AST activity, medium and low dose of l-Borneolum, high, medium and low dose of Borneolum syntheticum significantly reduced LDH activity (P<0.05, P<0.01). Serum SOD activity of rats in l-Borneolum high, medium, and Borneolum syntheticum high dose groups increased significantly (P<0.05, P<0.01). Serum MDA levels in Borneolum high, medium, low, and l-Borneolum high, middle dose groups significantly decreased (P<0.01). Conclusion::Three kinds of borneol in different dose groups can play different degrees of myocardial protection. Under the experimental conditions, there was a trend of l-Borneolum>Borneolum>Borneolum syntheticum in improving the efficacy of myocardial infarction, the dose-effect of Borneolum was negatively correlated, Borneolum syntheticum was positively correlated, and no significant dose-effect relationship between l-Borneolum.

ABSTRACT

Objective To sum up the diagnosis experience of unexplained hepatitis with hyperbilirubinemia (UHH) for establishing its diagnostic pathways and etiological factors. Methods By referring to the research progress at home and abroad, various examination items were made in order to form the clinical diagnosis pathway of UHH, on the basis of retrospective analysis and follow-up investigation of UHH patients. Using this pathway we carried out prospective diagnosis analysis for 223 patients admitted to Fifth Medical Center of Chinese PLA General Hospital from June 2014 to June 2017, in the order of preliminary, in-depth, and ultimate screening. Results A total of 181 cases were identified through the pathway screening (181/223, 81.17%). Two cases were etiologically diagnosed by primary screening (2/223, 0.90%), 18(18/223, 8.07%) by in-depth screening, and 161(161/223, 72.20%) by ultimate screening. There were still 42 cases (42/223, 18.83%) failing to make a definite diagnosis, among which 14 cases (14/223, 6.28%) failed to make a definite diagnosis after completing the diagnostic pathway, and 28(28/223, 12.55%) failed to complete the diagnostic pathway due to the critical condition and failure of liver puncture or rejection of genetic test. Among the 195 patients who completed diagnostic pathway, 181 cases were identified, and the actual etiology diagnosis rate was 92.82%. Among the 223 cases, 143(64.13%) were caused by drug-induced liver damage, 11(4.93%) by hereditary metabolic liver disease, 8(3.58%) by autoimmune liver disease, 5(2.24%) by infectious diseases, 14(6.28%) by other systemic diseases, and 42(18.83%) by undetermined causes. Conclusion Drug-induced liver damage, and genetic metabolic liver disease are common causes of UHH. The three-step screening pathway is effective for the diagnosis of UHH, and also simple and easy to practice, thus being worthy of promotion on a trial basis.

ABSTRACT

To determine the optimum conditions of supercritical CO2 extraction of Xiaoyaosan, and establish its fingerprint by gas chromatography-mass spectrometry (GC-MS), the yield of extract were investigated, an orthogonal test was used to quantify the effects of extraction temperature, pressure, CO2 flow rate and time, and fingerprint analysis of different batches of extracts were by GC-MS. The optimal extraction conditions were determined as follows: extraction pressure 20 MPa, extraction temperature 50 degrees C, CO2 flow rate 25 kg x h(-1), extraction time 3 h, and average yield 2.2%. The GC-MS fingerprint was established and 27 common peaks were found, whose contents add up to 81.89% of the total peak area. Among them, 21 compounds were identified, accounting for 53.20% of the total extract. The extraction process is reasonable and favorable for industrial production. The GC-MS method is accurate, reliable, reproducible, and can be used for quality control of supercritical CO2 extract from Xiaoyaosan.

ABSTRACT

The tail suspension test (TST), forced swimming test (FST) and chronic unpredictable mild stress (CUMS) model were used to evaluate the anti-depressant effect of supercritical CO2 extract from Compound Chaigui Fang (FFCGF). A nuclear magnetic resonance (NMR)-based metabonomics combined with multivariate statistical analysis was performed to explore the mechanism of FFCGF. Rats were conducted by CUMS procedure for 28 days and drugs were administrated at the same time. The body weight, sucrose preference, crossings and rearings in open-field tests were evaluated and the urine was collected simultaneously. The metabonomic profiles of rats' urine were analyzed by NMR and potential biomarkers were searched by multivariate statistical analysis. The results showed that administration of FFCGF significantly decreasing the immobility time in FST and TST and improving rats' body weight, sucrose preference, crossings and rearings in CUMS, which were indication that the anti-depressant effect of FFCGF was abvious. Significant differences in the metabolic profile of the CUMS treated group and the control group were observed, which were consistent with the results of behavioral tests. Decreased levels of acetic acid, succinic acid, 2-oxidation glutaric acid and citric acid and increased glycine and pyruvic acid in urine were significantly affected by the CUMS procedure and the 6 biomarkers were reversed evidently after administration of FFCGF. These changes were suggestion that the anti-depressant mechanism of FFCGF was associated with energy metabolism, lipid metabolism and amino acid metabolism.

ABSTRACT

OBJECTIVE@#To construct a strain of recombinant Mycobacterium smegmatis expressing the heat shock protein 65 (Hsp65) and human interleukin 2 (IL-2) fusion protein (rMS-Hsp65/IL-2) and to explore the effect of this construct on lymphocyte function in mice.@*METHODS@#The fusion gene encoding Hsp65-hIL-2 was cloned into shuttle vector pSMT3. The recombinant plasmid pSMT3-Hsp65-hIL-2 was transferred to Mycobacterium smegmatis by electroporation. Positive clones were selected by hygromycin and identified by PCR. The expression of fusion protein Hsp65-hIL-2 was verified using indirect immunofluorescence staining. Mice were immunized for two times by subcutaneously injection with 1×10(6) CFU rMS-Hsp65/IL-2 at a three-week interval. Two weeks after the second immunization, mice were sacrificed and the serum samples were collected for determination of anti-Hsp65 specific IgG. Splenic lymphocytes were isolated and treated with the rMS-Hsp65/IL-2 to determine lymphocytic proliferation activity by MTT assay. IFN-γ- and IL-2 in the medium of the treated cells were also determined by ELISA.@*RESULTS@#Successful construction of rMS-Hsp65/IL-2 was verified by PCR and immunofluorescence staining. Compared to the splenic lymphocytes isolated from mice immunized with Bacille Calmette-Guerin or mice immunized with Mycobacterium smegmatis alone, the splenic lymphocytes isolated from mice immunized with rMS-Hsp65/IL-2 showed a marked increase in the proliferation of lymphocytes, together with an increased production of important cytokines such as IFN-γ-and IL-2.@*CONCLUSIONS@#rMS-Hsp65/IL-2 markedly enhances lymphocyte function. Therefore, the fusion protein generated by rMS-Hsp65/IL-2 may be of potential value in generating an effective vaccine against tuberculosis.

ABSTRACT

<p><b>OBJECTIVE</b>To explore the protective effect and the mechanism of controlled hypotension induced by transcutaneous electrical acupoint stimulation (TEAS) combined with general anesthesia.</p><p><b>METHODS</b>Sixteen male Beagles were randomly divided into a group of controlled hypotension induced by simple general anesthesia (control group) and a group of controlled hypotension induced by TEAS combined with general anesthesia (observation group). All the animals were administered with combination of Isoflurane and Sodium Nitroprusside (SNP) for controlled hypotension without TEAS until the arterial pressure was lowered to 30% basic mean arterial pressure (MAP) for 60 min. In the observation group, TEAS (2 Hz/100 Hz, 3-5 mA) was applied to "Hegu" (LI 4) "Zusanli" (ST 36), "Sanyinjiao" (SP 6) and "Quchi" (LI 11) from the beginning of physiological conditions stability to the end of maintained low MAP for 60 min, but there was no TEAS in control group. The changes of MAP, the left intraventricular pressure (LIVP), T wave and ST-T segment of II lead electrocardiogram (ECG) were monitored with the physiological signal acquisition system, and myocardial apoptosis was detected by TUNEL method.</p><p><b>RESULTS</b>All the animals could maintain stable required low blood pressure. At one hour after cease of controlled hypotension, MAP of (109.56 +/- 6.14) mmHg returned to the basic level in the observation group, while MAP of (84.91 +/- 6.36) mmHg was still lower than its basic MAP of (111.02 +/- 4.15) mmHg in the control group (P < 0.05), showing significant difference in MAP between the two groups (P < 0.05). -dp/dtmax of (3156.32 +/- 332.82) mmHg/s showed significant lower than its basic value of (4585.33 +/- 638.55) mmHg/s when blood pressure increased for 1 h in the control group (P < 0.05), but there was no difference in the observation group. When the objective low MAP maintaining for 60 min the ST segment was decreased significantly in the control group (P < 0.05), but there was no difference in the observation group. The numbers of positive apoptosis cardiocytes in the observation group were (24.67 +/- 2.45) cells/mm2, which were significantly fewer than (37.89 +/- 1.90) cells/mm2 in the control group (P < 0. 05).</p><p><b>CONCLUSIONS</b>TEAS combined with general anesthesia for controlled hypotension can significantly shorten restoration time of MAP, help to improve myocardial ischemia and the cardiac functional recovery and reduce myocardial apoptosis so as to produce myocardial protection.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the long-term effect and clinical value of endoscopic mucosal resection (EMR) with transparent cap for dysplasia and early-stage cancer of the esophagus and gastric cardia.</p><p><b>METHODS</b>From September 1996 to June 2007, 154 lesions in the esophagus or gastric cardia of 147 patients were treated using EMR with transparent cap. Among the lesions, there were 69 early-stage squamous-cell carcinomas in 64 patients and 47 squamous cell precancerous lesions of the esophagus in 45 patients, with an average lesion size of (14.8 +/- 6.1) mm (range, 3-40 mm), furthermore, there were 23 early-stage adenocarcinomas in 23 patients and 15 precancerous lesions in the gastric cardia in 15 patients, with an average lesion size of (8.2 +/- 4.3) mm (rang, 5-25 mm). All lesions were finally confirmed histopathologically.</p><p><b>RESULTS</b>Of the 154 lesions, 139 (90.3%) were resected completely through EMR procedure. A close relationship between the complete resection rate and the lesion size was observed. The bigger the lesion size, the lower the complete resection rate. Endoscopic follow-up was carried out in 7 patients for more than 10 years, in 43 for 5 - 10 years, in 31 for 3 - 5 years and in 66 for less than 3 years. Of 11 dead patients during following-up, 10 died of other diseases, only 1 of recurrence. The 5-year survival rate was 96.2% for early-stage esophageal cancer, and 100% for early cancer of the gastric cardia. Perioperative complications included oozing bleeding in 5 patients (3.4%) and stricture in 1 (0.7%), no perforation occurred in this series.</p><p><b>CONCLUSION</b>Endoscopic mucosal resection is suitable to treat precancerous lesions or early-stage esophageal cancers without invasion into submucosa. Compared with conventional resection through open thoracotomy, similar long-term survival and curative effect can be achieved by this EMR treatment, preserving a good quality of life.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To study the value of carboxyhemoglobin (COHb) in the diagnosis of neonatal jaundice.</p><p><b>METHODS</b>This study consisted of 189 patients with neonatal jaundice due to hemolytic disease (n=75), infectious disease (n=52), intracranial hemorrhage (n=32) and breast-milk feeding (n=30). One hundred and forty-two neonates without pathological jaundice that were gestational age, postnatal age- and birth weight-matched were used as the Control group. The level of arterial capillary blood COHb was detected by a 270 CO-oximeter connected to an 800 series system. Total serum bilirubin (STB) content was measured using an Abbott Spectrum CCX chemistry analyzer. The levels of COHb and STB were measured at baseline, and again in patients with jaundice due to hemolytic disease after intravenous gammaglobulin treatment for 2 days.</p><p><b>RESULTS</b>The levels of COHb [(3.64 +/- 0.83)%] and STB (330.84 +/- 77.15 micromol/L) in patients with jaundice due to hemolytic disease were significantly higher than those measured in the Control group [COHb (2.38 +/- 0.35) %; STB 130.18 +/- 32.86 micromol/L] (P < 0.01). The levels in patients with jaundice due to intracranial hemorrhage were also significantly higher than those in the Control group [COHb (2.48 +/- 0.53) % vs (2.24 +/- 0.32) %; STB 184.15 +/- 29.35 micromol/L vs 112.11 +/- 17.45 micromol/L; P < 0.05]. The patients with jaundice due to infectious disease or breast-milk feeding only demonstrated higher levels of serum STB (P < 0.01) while COHb levels were not different compared with the Control group. The patients with jaundice due to hemolytic disease or intracranial hemorrhage presented with hemolytic unconjugated hyperbilirubinemia and had significantly higher COHb levels and lower STB levels than those patients with nonhemolytic unconjugated hyperbilirubinemia (caused by breast jaundice) (P < 0.01). The levels of COHb [(2.68 +/- 0.51) %] and STB (230.18 +/- 42.96 micromol/L) in patients with jaundice due to hemolytic disease decreased markedly after intravenous gammaglobulin treatment (P < 0.01).</p><p><b>CONCLUSIONS</b>The COHb level can be used as a supplementary indicator of increased bilirubin production. The elevation of COHb can be useful in the diagnosis of neonatal jaundice since COHb is elevated in hemolytic disease and intracranial hemorrhage.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the clinical value of esophageal mucosal iodine stain during esophagoscopy for patients with early esophageal carcinoma or precancerous lesions without swallowing symptoms, through analyzing the correlation between endoscopic findings and pathological results of biopsy on the suspicious spots.</p><p><b>METHODS</b>For 366 patients examined by iodine stain during esophagoscopy, the position, size, shape and boundary of all visible unstained lesions were recorded and multiple biopsies were taken on the unstained spots.</p><p><b>RESULTS</b>Before iodine stain, 462 lesions had been discovered in 366 patients. However, 478 abnormal lesions stained in 341 patients were detected after iodine stain, the remaining 25 gave no abnormal findings. More than 1/3 of patients were found to have more than 2 abnormally stained lesions. 28.4% of them (104 cases) had moderate or severe dysplasia or early esophageal cancer. The sensitivity of iodine stain in this series was 89.8%.</p><p><b>CONCLUSION</b>Iodine stain is very useful in detecting occult early esophageal carcinoma and precancerous lesions. The degree of coloration and the margin of suspicious spots are closely correlated with the pathological results.</p>
