Objective To analyze clinical features and sum up experience for the treatment of ischemic bowel disease. Methods Clinical data of 73 patients with the diagnosis of ischemic bowel disease were retrospectively analyzed. ResultsTwenty-eight patients were male and 45 patients were female. The median of age was 65 years (range of 38 to 89 years). Forty-eight patients were associated with hypertension, 23%(17/73) patients had a history of coronary disease and 15% (11/73) had diabetes. Seventy patients presented symptom of abdominal pain and 93% (68/73) had hematochezia. Symptoms relieved by conservative treatment in 96% (63/66) patients. Nine patients underwent a surgery. One patient died of sepsis postoperatively. One suffered from colostomy necrosis and leakage of the rectum segment. Conclusion 1. Elder patients presenting symptoms of abdominal pain and hematochezia, especially with a history of cardio-cerebrovascular disease and diabetes should be considered for the possibility of ischemic bowel disease. 2. Most patients with ischemic bowel disease could be successfully treated by conservative therapy. 3. Surgery for patients with chronic relapsing and nonresponsible symptoms was difficult and patients often suffer from high postoperative complications.

Human arrest defective 1 (hARD1) is an acetyltransferase; its physiological significance remains unclear. To explore the relationship between ARD1 protein and tumors, we detected the hARD1 protein in tumor tissues in vivo. We cloned hARD1 gene from Hela cell and construct recombinant plasmid pET28b-hARD1. The recombinant plasmid was transformed into E. coli BL21 (DE3)plysS. hARD1 protein was expressed by inducing with IPTG(1 mmol/L) and purified up to 95% through Ni2+ chelation affinity chromatography. We used the purified hARD1 protein as antigen immunized the Balb/c mice and obtained the hARD1 specific polyclonal antiserum. Through immunohistochemical analysis of different tumor tissues in vivo, we found that hARD1 expressed at high frequency in breast cancer, prostate cancer and lung cancer, especially, hARD1 expression frequency in breast cancer was up to 70%, which is higher than in the other tumors. These results indicate that the high expression level of hARD1 could be an indicator of the breast cancer. This new finding would be a foundation to further explore the relationship between breast tumor and hARD1.

BACKGROUNDTrichophyton rubrum is superficial fungi characteristically confined to dead keratinized tissues. These observations suggest that the soluble components released by the fungus could influence the host immune response in a cell in contact-free manner. Therefore, this research aimed to analyze whether the culture supernatant derived from T. rubrum grown in the nail medium could elicit the immune response of keratinocyte effectively.

METHODSThe culture supernatants of two strains (T1a, T XHB ) were compared for the β-glucan concentrations and their capacity to impact the innate immunity of keratinocytes. The β-glucan concentrations in the supernatants were determined with the fungal G-test kit and protein concentrations with bicinchoninic acid protein quantitative method, then HaCaT was stimulated with different concentrations of culture supernatants by adopting morphological method to select a suitable dosage. Expressions of host defense genes were assessed by quantitative polymerase chain reaction after the HaCaT was stimulated with the culture supernatants. Data were analyzed with one-way analysis of variance, followed by the least significant difference test.

RESULTSThe T. rubrum strains (T1a and T XHB ) released β-glucan of 87.530 ± 37.581 pg/ml and 15.747 ± 6.453 pg/ml, respectively into the media. The messenger RNA (mRNA) expressions of toll-like receptor-2 (TLR2), TLR4, and CARD9 were moderately up-regulated in HaCaT within 6-h applications of both supernatants. HaCaT cells were more responsive to T1a than T XHB . The slight increase of dendritic cells-specific intercellular adhesion molecule 3-grabbing nonintegrin expression was faster and stronger, induced by T1a supernatant than T XHB . The moderate decreases of RNase 7, the slight up-regulations of Dectin-1 and interleukin-8 at the mRNA level were detected only in response to T1a rather than T XHB . After a long-time contact, all the elevated defense genes decreased after 24 h.

CONCLUSIONThe culture supernatant of T. rubrum could directly and transiently activate the innate immune response of keratinocytes.

OBJECTIVETo construct cDNA subtracted libraries from gastric dysplasia and further screen differentially expressed genes.

METHODSRelatively pure dysplasia and normal tissue were procured by manual microdissection, and amplified by cDNA-PCR, which was used to carry on for suppression subtractive hybridization (SSH). Subtracted cDNA fragments were linked with vector, cloned, screened, sequenced, and made homologous search. Differentially expressed fragments were verified by dot hybridization.

RESULTSTwo subtracted cDNA libraries were constructed. Among 26 sequenced clones, 15 fragments corresponded to known genes, 3 fragments were known EST and 8 fragments were unknown EST (GenBank BQ164614-BQ164616, BQ291516-BQ291520). Fifteen fragments were verified to be differentially expressed in gastric dysplasia.

CONCLUSIONSSubtracted cDNA libraries from gastric dysplasia are constructed using combination of microdissection-cDNA PCR and SSH setup in our laboratory. Some fragments have been screened and verified to help to search for novel associated genes with gastric carcinogenesis.

OBJECTIVETo study the rotary angle and image features, so as to help early diagnosis.

METHODSFour adult cervical spine (C1-T1) specimens were used, including 2 males and 2 females,ranging in age from 28 to 40 years old. X-ray and CT examination were performed before the experiment. C2-C4 and C5-T1 were fixed respectively using self-made clamp. Unilateral locked facet of cervical spine was simulated under the violence of inflection and rotation, in which the muscle contraction was partially simulated, and at last the plain radiographs and CT of unilateral locked facet of cervical spine were analyzed.

RESULTSIn unilateral locked facet of cervical spine, the average rotary angle was 19.75 degrees, and average forward shift of vertebral was 3.68 mm. The intervertebral foramina below the injury plane were showed at 0 degrees,10 degrees, 180 degrees,190 degrees; the intervertebral foramina above the injury plane were showed at 150 degrees,160 degrees, 00 degrees, -10 degrees, and the facet was locked or in disorder at the injury plane. The intervertebral foramina at the anterior oblique position was bigger in interlocking side, but it was smaller in the opposite side. CT scan showed rotary spine, the naked facet sign; coronal plane reconstruction showed bilateral asymmetry; sagittal plane reconstruction obviously showed unilateral locked facet.

CONCLUSIONX-ray and CT both can independently diagnose unilateral locked facet of cervical spine. CT and three-dimensional reconstruction are more better than X-ray to diagnosing it.

Objective To observe the clinical efficacy of acupuncture plus medication in treating chronic pelvic inflammatory disease. Method By using the random number table, sixty-eight patients with chronic pelvic inflammatory disease were randomized into an acupuncture-medication group of 34 cases and a medication group of 34 cases. The clinical efficacies were compared after 2 courses of treatment, and the symptoms and body signs scores and syndrome score of traditional Chinese medicine (TCM) were also compared. Result There was a significant difference in comparing the therapeutic efficacy between the acupuncture-medication group and the medication group (P<0.05). After the treatment, the symptoms and body signs scores and TCM syndrome score dropped significantly in both groups (P<0.05), indicating that the two groups both had improvement in the symptoms, body signs and TCM syndrome; there were significant between-group differences in comparing the score differences in the symptoms and body signs scores and TCM syndrome score after the treatment (P<0.05), and the acupuncture-medication group was higher than the medication group. Conclusion Acupuncture plus medication can better ameliorate the symptoms and body signs and TCM syndrome in chronic pelvic inflammatory disease.

BACKGROUNDThe severity of respiratory distress was associated with neonatal prognosis. This study aimed to explore the clinical characteristics, therapeutic interventions and short-term outcomes of late preterm or term infants who required respiratory support, and compare the usage of different illness severity assessment tools.

METHODSSeven neonatal intensive care units in tertiary hospitals were recruited. From November 2008 to October 2009, neonates born at ≥ 34 weeks' gestational age, admitted at < 72 hours of age, requiring continuous positive airway pressure (CPAP) or mechanical ventilation for respiratory support were enrolled. Clinical data including demographic variables, underlying disease, complications, therapeutic interventions and short-term outcomes were collected. All infants were divided into three groups by Acute care of at-risk newborns (ACoRN) Respiratory Score < 5, 5 - 8, and > 8.

RESULTSDuring the study period, 503 newborn late preterm or term infants required respiratory support. The mean gestational age was (36.8 ± 2.2) weeks, mean birth weight was (2734.5 ± 603.5) g. The majority of the neonates were male (69.4%), late preterm (63.3%), delivered by cesarean section (74.8%), admitted in the first day of life (89.3%) and outborn (born at other hospitals, 76.9%). Of the cesarean section, 51.1% were performed electively. Infants in the severe group were more mature, had the highest rate of elective cesarean section, Apgar score < 7 at 5 minutes and resuscitated with intubation, the in-hospital mortality increased significantly. In total, 58.1% of the patients were supported with mechanical ventilation and 17.3% received high frequency oscillation. Adjunctive therapies were commonly needed. Higher rate of infants in severe group needed mechanical ventilation or high frequency oscillation, volume expansion, bicarbonate infusion or vasopressors therapy (P < 0.05). The incidence of complications was also increased significantly in severe group (P < 0.05). The in-hospital mortality in the severe group was significantly higher than other two groups (P < 0.05). ACoRN Respiratory Score was correlated with Score for Neonatal Acute Physiology-Version II (SNAP-II) (P < 0.01). High gestational age, high SNAP-II score and oxygenation index (OI), and Apgar score at 5 minutes < 5 were independent risks for death.

CONCLUSIONSNeonatal respiratory distress is still a common cause of hospitalization in China. Illness severity assessment is important for the management. ACoRN Respiratory Score which correlated with SNAP-II score is easy to use and may be helpful in facilitating the caregivers in local hospital to identify the early signs and make the transfer decision promptly.

OBJECTIVESTo analyze the survival outcomes of the surgery for colorectal cancer with liver metastases (CRCLM), and study the mode of multi-disciplinary team (MDT) for CRCLM.

METHODSThe retrospective analysis was conducted for 38 patients with CRCLM received MDT management and surgical treatment from January 2009 to August 2011. The peri-operative and survival outcomes of MDT and surgery were evaluated.

RESULTSAll the cases met the present criteria of resetability for CRCLM, but only 4 cases (10.5%) met the previous one. Coloproctectomy and hepatectomy were performed in all cases, with 39 colorectal neoplasms and 155 liver lesions removed. One case died of postoperative septic shock. Colorectal and hepatic specific complications were absent in the others patients except one case of biliary leak which was treated with conservative management. Neoadjuvant chemotherapy was arranged in 13 cases. Adjuvant chemotherapy was administered for every patient. After a mean follow-up of (22 ± 10) months according to the finding time of liver metastases, recurrence and metastases were observed in 16 cases and 6 cases died of late-stage cachexia. The 1-, 2- and 3-overall survival rate were 94.4%, 85.3% and 75.8% respectively, and the 1-, 2- and 3-disease-free survival rate were 70.1%, 54.2% and 54.2% respectively.

CONCLUSIONSMDT mode for resectable CRCLM is recommendable. Surgical resection of CRCLM is feasible and safe, which seems to achieve favourable short-middle oncologic outcomes. And long-term survival is expected.

To evaluate the efficacy and safety of left atrial appendage occlusion (LAAO) in patients with atrial fibrillation (AF) over 75 years. A total of 82 patients with AF who underwent LAAO successfully in Beijing Anzhen Hospital from March 2014 to March 2019 were divided into two groups according to age: the elderly group (aged>75 years) and the young group (aged ≤75 years). Risk of perioperative complications and incidence of ischemic stroke and major bleeding during follow-up were retrospectively analyzed. The results showed that there were no significant differences in procedure-related ischemic stroke(0 vs.1.6%, P=0.768) and major bleeding (0 vs.1.6%, P=0.768) during perioperative period between the two groups. No complications as death or pericardial tamponade occurred in the two group. During a (25.9±15.9) months period of followed up, ischemic stroke event rate was 3.6/100 person-years in the elderly group and 4.9/100 person-years in the young group, respectively. Major bleeding event rate was 2.5/100 person-years in the elderly group and 0/100 person-years in the young group, respectively. Compared with the expected ones, the relative risk reduction (RRR) of stroke in the elderly group was more profound than that in the young group (32.0% vs. 25.0%), while the risk of major bleeding in the young group was significantly lower than that in the elderly group (RRR 100% vs. 56.9%). Therefore, LAAO might be suitable for stroke prevention in the elderly AF patients.
