Objective To analyse the clinical characteristics,therapeutic modalities and prognosis of pulmonary large cell neuroendocrine carcinoma(LCNEC). Methods The clinical data of 14 patients with pulmonary LCNEC confirmed by surgery were retrospectively reviewed. Results No case was correctely diagnosed before surgery.The immunohistochemical amalysis of the specimens revealed the characters of endocrine carcinoma.Twelve cases received adjuvant chemotherapy of platinum agents,but recurrence or metastasis was found in 8 of them several months after surgery.The median survival time was 19 months.The 1-year,2-year and 3-year survival rate were 85.7%(12/14),21.4%(3/14) and not more than 14.3%(2/14),respectively.The statistical analysis showed that the stage,lymph node metastasis and postoperative adjuvant chemotherapy may have impacts on the prognosis of pulmonary LCNEC. Conclusion Pulmonary LCNEC is a carcinoma with poor prognosis,high tendency of invasion and metastasis.The stage of disease,lymph node metastasis,and adjuvant chemotherapy may be related to the prognosis.

Objective:To investigate the effect of JAK2 V617F gene mutation status and burden on BCR-ABL-negative myeloproliferative neoplasms (MPN).Methods:Clinical data of 199 patients with MPN in Cangzhou Central Hospital in Hebei Province from September 2015 to January 2020 were retrospectively analyzed, and the correlations of JAK2 V617F gene mutation burden with clinicopathological features and prognostic score of MPN patients were analyzed.Results:Of the 199 BCR-ABL-negative MPN patients, 138 patients (69.4%) were positive for JAK2 V617F mutation; of these patients, 64 (88.9%) of 72 patients with polycythemia vera (PV) were mutation-positive, 54 (53.5%) of 101 patients with essential thrombocytosis (ET) were positive, 20 (80.0%) of 25 patients with myelofibrosis (MF) were mutation-positive, and 1 patient with hypereosinophilic syndrome (HES) was mutation-positive. About 55.1% (76/138) of patients had a high JAK2 V617F mutation burden. The mutation burden in PV group was the highest, MF was the second, and ET was the lowest; the mutation burdens in these three groups were (73.9±18.3)%, (59.9±25.2)% and (25.0±16.5)%, respectively. Mutation burden was positively correlated with the white blood cell counts of patients with PV, ET and MF ( r values were 0.626, 0.675 and 0.796, all P < 0.01). JAK2 V617F mutation burden was positively correlated with the prognostic scores of patients with PV and ET ( r values were 0.296 and 0.404, both P < 0.05). Conclusion:The JAK2 V617F mutation burden of BCR-ABL-negative MPN patients is related to clinicopathological factors, and the prognosis of patients with high JAK2 V617F mutation burden is poor.

Objective To elucidate the roles of TANK-binding kinase-1(TBKl)in hepatitis B virus (HBV)infection induced interferon antiviral immunity.Methods Peripheral blood monocytes were separated by CD14 magnetic microbeads from healthy volunteers(HV)and chronic hepatitis B(CHB)patients.Purified mDCs were induced and proliferated in the culture medium with human granulocyte-macrophage concentration of 25 mg/L were stimulated.The mRNA expressions of TBK1,interferon regulatory factor (IRF)3 and interferon(IFN)-βwere quantified by real time polymerase chain reaction(PCR).The levels of IFN-β in supernatants were determined by enzyme-linked immunosorbent assay(ELISA).Reslllts The mRNA levels of TBK1,IRF3 and IFN-β did not change significantly at 0,12,24 and 48 h after the significantly at 0, 12, 24 and 48 h in CHB group, whereas, it was significantly up-regulated at 12 h in HV group. Conclusions Our results suggest that there may be some disorders in host antiviral signal transduction pathways downstream the binding between ligands and receptors on mDC surface. The insufficient IFN-β expression after HBV infection may result in persistent chronic infection.

OBJECTIVETo evaluate the efficacy of water knife needle release combined with bone peptide injection in the management of heel pain.

METHODSThirty-five patients with unilateral heel pain were treated with water knife needle release and bone peptide injection under local anesthesia. The deep tissue with the tenderness was released in the operation, and the result was evaluated 1 week after the surgery to decide whether to conduct another surgery. No more than 3 treatment sessions were administered. The efficacy was evaluated according to nimodipine method by the principles of Chinese clinical drug guidance, and the complications of the surgery were observed.

RESULTSSix months after the surgery, 28 cases had excellent results, 3 had good outcomes, 2 showed improvement, and 2 failed to respond favorably, with a rate of good and excellent result of 94.2%. No adverse side effect was recorded in the follow up of the patients.

CONCLUSIONWater needle knife release combined with bone peptide injection can produce a good result in the treatment of heel pain.

OBJECTIVETo analyze the clinical characteristics and treatment of eosinophilic gastroenteritis (EG) in children.

METHODA retrospective analysis of the clinical manifestation, laboratory test, endoscopy, biopsy, bone marrow examination and treatment of 6 children diagnosed with EG in Beijing Children's Hospital seen from Jun. 2005 to May 2009 was performed.

RESULTFive of the cases were boys and 1 was girl, the range of age was from 2 to 13 years; food allergy test was positive in 4 cases. Clinical manifestations included:abdominal pain, diarrhea, vomiting, digestive tract hemorrhage, and ascites was found in 4 children. The eosinophilic cell count in blood increased in 5 cases [(160 - 13,560) × 10(6)/L]. The percentage of eosinophilic cell in bone marrow increased in 6 cases (0.18 - 0.41). Beside stomach and duodenum, anatomical foci were found in mesentery (5 cases), small intestine (4 cases), colon (3 cases), and esophagus (2 cases). Endoscopy and imaging showed edema, congestion, erosion, ulcer, bile reflux and gastric juice retention. Stomach and duodenum pathological changes included epithelial erosion, large quantities of eosinophilic cell infiltration in lamina propria and scattered lymphoid cells, which were more obvious in duodenum. In the group received glucocorticoid therapy, clinical symptoms disappeared 3 days later, the eosinophilic cell count in blood returned to normal one-week later;in the group of non-glucocorticoid therapy, most of the clinical symptoms disappeared after two weeks. The eosinophilic cell count in blood was still high 5 weeks later.

CONCLUSIONCompared to the common gastroenteritis, gastrointestinal symptoms in EG cases were nonspecific, the increase of blood eosinophilic cells can suggest the possibility of EG, but biopsy is the key to the diagnosis of EG. The therapeutic effect of glucocorticoid seemed to be better than non-glucocorticoid therapies in the improvement of clinical symptoms and the decrease of blood eosinophilic cell.

To investigate the knowledge, attitude and practice (KAP) on rabies among a mass of the exposed population in Beijing so as to provide scientific evidence for development of measures on the prevention and protection of rabies, the descriptive studies were employed, in which patients were interviewed face to face with a standard questionnaire in hospital or the center for disease control and prevention (CDC), including history of exposure, knowledge on rabies, post-exposure treatment etc. Of 478 respondents, 76% of them were bitten on the upper limbs with the exposure proportions in category Ⅰ, Ⅱ and Ⅲ of 24%, 70% and 6% respectively. The proportions of awareness of knowledge in rabies before biting, its prevention, the correct measure to treat their wounds themselves, rabies vaccine inoculation, and injections with rabies antiserum constituted in 82%, 55%, 59%, 99% and 22% respectively. Result of this investigation indicates that most of the people investigated had a lower awareness of knowledge on rabies, the correct measures to treat rabies after biting as well as the measures to prevent rabies, suggesting that community-based prevention and control measures should be emphasized, especially targeting the population with high risk and the heath education on rabies should performed promptly by several governmental departments.
