Chronic constipation(CC)is one of the most common gastrointestinal disorders. Treatment of CC includes drug and non-drug treatment. Biofeedback(BF)is a psychological behavior therapy and has become the first-line therapy of CC. However,the efficacy of BF reported varied substantially. This article reviewed the evaluation of efficacy of BF on CC.

Objective To investigate the value of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) in the diagnosis of pulmonary cryptococcosis.Methods 15 patients who were diagnosed as pulmonary cryptococcosis were retrospectively studied,all of them were examined by sputum smear,X ray,CT and EBUS-TBNA.Results 15 patients who received EBUS-TBNA were diagnosed pulmonary cryptococcosis by pathological methods and germiculture,during the process no complication was detected.Conclusion EBUS-TBNA is a safe and effective means in the diagnosis of pulmonary cryptococcosis for pulmonary cryptococcosis patients hard to be diagnosed clinically.

Method Summarized the nursing points of 24 patients who have accepted the breast tumor excision by endoscope. Results The key points of successful operation were sufficient preparation before the operation, the special skills of nurses, exactly and quickly transfer instruments and expert cooperation. Conclusion Paving attention on psychological nursing, the correct and skillful nursing care can reduce the operation time, and then make sure the successful operation.

Left ventricular noncompaction(LVNC)describes a rare cardiomyopathy of unknown etiology characterized by the presence of prominent trabeculations and deep intertrabecular recesses.It is one of the three major cardiomyopathies among children.LVNC can have different inheritance patterns, including X-linked recessive, autosomal dominant, and mitochondrial inheritance.Mutations in genes encoding sarcomere or cytoskeletal proteins have been identified as causes of LVNC.As a comprehensive cardiac event with serious complications such as life threatening arrhythmias, heart failure and thromboembolism, LVNC is mainly diagnosed through echocardiography, cardiac magnetic resonance and other examinations.Early improvement of genetic evaluation, screening of family members for the mutation, close follow-up of high-risk patients, and early management of complications will help to improve patients′ quality of life and prognosis.

ObjectiveTo determine the effect of acute and chronic spinal cord injury (SCI) resulted from thoracic cord transection on the urinary bladder spinal neural pathway.Methods76 adult Sprague-Dawley rats were randomly divided into 4 groups, non-SCI, SCIa, SCIb and SCIc respectively. The non-SCI rats underwent no surgical procedure except Pseudorabies virus (PRV) tracer injection into the bladder tissue, while the rats of other groups were spinalized and given PRV injection at different time after SCI. Transcardiac perfusion fixation was done in appropriate survival periods after PRV injection. Then sections of dorsal root ganglion (DRG) and spinal cord were processed for visualization of virus by the Streptavidin-Peroxidase (SP) immunohistochemical procedure. All sections were measured with the Olympus Cue-2 image analysis system.ResultsThe bladder weights in SCIb and SCIc groups markedly increased (P<0.001). The time-ordered flow charts of PRV tracing were similar in the non-SCI rats and in the SCI rats. The cross-sectional area of the labeled DRG cell profiles increased significantly after SCI (P<0.001). The number of labeled cells in dorsal horn in L6 and S1 segments 3 days after PRV injection markedly increased in chronic SCI rats, and so did the number of labeled motor neurons 4 days post-injection. ConclusionThe acute and chronic SCI have little effect on the process of virus transneuronal transport below the level of lesion. Subsequent to chronic SCI, marked reorganization of the micturition reflex pathways occurs.

Although the percentage of preterm infants developing intraventricular haemorrhage (IVH) has been greatly re-duced in the past three decades, increased survival of extremely preterms has meant that severe IVH with subsequent posthae-morrhagic hydrocephalus is still one of the serious unsolved problems for managements of preterms. Therapeutic interventions for posthaemorrhagic hydrocephalus include serial lumbar punctures, repeated aspiration through a ventricular access device, ventriculoperitoneal shunting, drainage, irrigation and fibrinolytic therapy, diuretic therapy treatment to reduce cerebrospinal fluid production, intraventricular fibrinolytic therapy, etc. This review summarizes the current concepts on the pathophysiology, inter-vention indications, and the effectiveness and safety of different interventions of subsequent posthaemorrhagic hydrocephalus.

Objective To analyze the clinical characteristics of drug-induced liver injury (DILI) from Chinese literatures published in Chinese Periodical Full-text Database (CNKI) from 2007 to 2011.Methods Using drug-induced liver injury as key words,the literatures in CNKI were searched,and the data of age,gender,medication,clinical manifestation and prognosis were analyzed.Results In search of CNKI,281 literatures were collected; finally 111 relevant papers were obtained.Total 10 693 cases of DILI were included with a male/female ratio of 1.14:1 and a mean age of 45.6 y ranging from 7 months to 93 y.Among 1093 cases with the age grouped,the highest incidence of DILI was in age 41-60 y(38.52％)and 20.68％ patients were over 60 y.Among 6592 cases with clinical manifestation recorded,43.51％ patients were asymptomatic and abnormal liver function was detected in health check-up; and others presented nonspecific gastrointestinal symptoms,including fatigue,nausea,vomiting and jaundice.In 9340 cases with medication recorded,the 6 most common drugs inducing DILI were antituberculotics (32.74％),Chinese herbs(22.12％),antibiotics(9.18％),antineoplastics(6.34％),NSAIDs (4.80％)and antithyroid drugs (4.37％).The most common type of toxicity was hepatocellular injury (63.66％,4438/6971).In general the prognosis was good with a fatality rate of 1.67％.Conclusions Antituberculotics and Chinese herbs are the main causes of DILI.Some DILI patients have occult onset and others have nonspecific gastrointestinal symptoms.Most patients have good prognosis if they are treated timely.

SALL4 gene is closely related to body malformations related diseases, embryonic stem cell development, and hematopoietic malignancies. SALL4 can activate hematopoietic stem cell through Wnt signaling pathways, and promote continued proliferation of leukemia stem cells, leading to leukemia. In-depth study of SALL4 gene and its protein function will help clarify the pathogenesis of leukemia, providing a new target for the treatment of leukemia.

OBJECTIVE To measure the dexamethasone concentration in the cochlear tissue after postaurical and intramuscular administration. METHODS After bilateral adrenalectomy,animals were divided into three groups:postaurical injection group,intramuscular injection group,and physiological saline injected blank control group.At 0.25,0.5, 2.5,5,12,24,72 h after injection(1mg/100g), cochleae together with the intact endolymphatic sac were removed and homogenated.After that, the dexamethasone was detected by enzymelinked immunosorbent assay(ELISA).RESULTS The dexamethasone levels in the cochlear tissue in postaurical injection group were significantly higher than that in the intramuscular injection group.In the postaurical administration group,a mean peak cochlear tissue concentration of(175.2?36.0) ng/ml was detected at 0.25 h after injection,then declined obviously 12 h and was below detection limits by 24h.While in the intramuscular administration group, a mean peak concentration was observed 2.5 h at the concentration of(141.1?8.9) ng/ml,then rapidly declined from 5h and beyond detection by 24 h.CONCLUSION Compared with intramuscular administration,the dexamethasone levels in the postaurical injection group were significantly higher, with peak concentration reached earlier,and last longer.
