A case of traumatic delayed meningo-encephalocele suffered orbital fracture, but bony defects in frontal sinus had not been found on CT scanning. We treated the patient with surgery of intranasal endoscopy and repaired the skull base defect successfully during the first attempt. There was no recurrence in 10 months followed up. The leak site may not correlate with imaging in traumatic delayed meningo-encephalocele by comparing operative findings with the imaging estimate and endoscopy. Therefore, endoscopical approaching is effective in seeking and treatment.

Objective: To study the factors and preventive method of post-operative complications of spinal implant operation. Methods: The post-operative complication of 451 cases who had undergone spinal implant operation were analysed retrospectively. The relative factors of complications were analyzed. Results: Infection, thrombosis of deep vein and failed fusion were the most common complications. Among the factors, the age, operation time and blood lose during operation were closely related with the complication. Using antibiotic was effective to reduce the infection. Conclusion: It is effective to reduce the post-operative complication of spinal implant operation by proper pre-operative evaluation. Using antibiotic to control other diseases is also effective.

Objective To investigate the effects of intense pulsed light(IPL) on the collagen metabolism in human fibroblasts.Methods The callan foreskin fibroblasts were cultured and treated with different wave length and designed dose of IPL irradiation(590-1 200 nm,and 29 J/cm2),while 10 without IPL irradiation as controls.By culturing 1,12,24 and 48 h after the irradiation,the synthesis of collagen was measured by 3H-proline incorporation determination. Results The synthesis of collagen activity increased significantly(P

Objective To explore the effectiveness of a respiratory function training instrument with stable chronic obstructive pulmonary disease (COPD) patients.Methods Sixty-seven COPD patients in the stable period were randomly divided into a treatment group of 36 and a control group of 31 using a random number table.Both groups were given conventional pulmonary rehabilitation,including half-closed lip respiration,abdominal respiration and upper limb training.The treatment group was additionally provided with 30 minutes of respiratory training using a respiration function training instrument 5 times per week for 6 months.Both groups were assessed for their mobility,life quality and pulmonary function using the 6-minute walk test (6 MWT),a COPD assessment test (CAT),the BODE index,forced vital capacity (FVC),forced expiratory volume in one second (FEV1) and surface electromyography (SEMG) of the respiratory muscles before and after the 6-month intervention.Results Before the treatment there were no significant differences between the two groups in terms of any of the measurements.After the treatment,significant improvement was observed in the average 6 MWT,CAT,BODE index and SEMG results in both groups,but with significantly greater improvement in the treatment group.The average FVC and FEV1 results did not improve significantly,so after the intervention there was still no significant difference between the groups.Conclusions Respiratory training using the pulmonary function training instrument can improve the mobility,life quality and the functioning of the respiratory muscles of COPD patients in the stable period.

Purpose To compare the CT features of hepatic metastases of gastro-entero-pancreatic adenocarcinomas with and without neuroendocrine differentiation [NED(+) and NED(-)] and to explore the value of CT features in differentiation of the two groups.Material and Methods From January 2009 to December 2015,abdominal CT scans of 17 pathologically proved cases of NED(+) gastro-entero-pancreatic adenocarcinomas with hepatic metastases and 34 pathologically proved cases of NED(-) hepatic metastases with sex,age and primary site matched were retrospectively reviewed.CT features including hepatic metastases number,size,distribution,shape and enhancement were assessed,as well as presence of lymphadenopathy or ascites.Differences of CT features between the two groups were analyzed.Results Compared with NED(-) group,hepatic metastases of NED(+) group more frequently demonstrated a peripheral enhancement on artery phase (94.1％ vs.44.1％,P＜0.05),and more washout on portal venous phase (41.2％ vs.5.9％,P＜0.05),while hepatic metastases of NED(--) group showed more plateau type (91.2％ vs.58.8％).There was no significant difference of other findings between the two groups (P＞0.05).Logistic regression revealed that enhancement area in hepatic artery phase and enhancement changes in portal venous phase were independent factors for differential diagnosis (P＜0.05).The area under the ROC curve of combining the two features was 0.811 (P＜0.05).Conclusion There are some different CT enhancement features between NED(+) and NED(-) hepatic metastases of gastro-entero-pancreatic adenocarcinomas,which are helpful in differential diagnosis.

In recent years, with the constant increase in the population with hypoimmunity, bacterial and fungal infections have been increasing. Due to the drug resistance, clinically optional anti-bacterial and antifungal medicines become increasingly limited. Scutellaria baicalensis, a species of perennial herbaceous plant of scutellaria genus of lamiaceae family, and its effective components have multiple pharmacological effects such as anti-inflammation, anti-oxidation, anti-tumor, anti-microbial. Especially, its remarkable antibacterial and antifungal activities are of great significance to treat the increasing number of cases with drug-fast bacterial and antifungal infections. In this paper, the authors summarized the advance in studies on antibacterial and antifungal effects and mechanisms in recent years on the basis of the domestic and foreign studies on S. baicalensis and its effective ingredients.

OBJECTIVETo investigate the effects of ethyl acetate extract of Huanglian Jiedu decoction (EAHD) on hyphae development of Candida albicans.

METHODInverted microscope, fluorescence microscope, SEM were applied to inspect the Morphological change of C. albicans treated by EAHD at different concentrations. Solid agar plate was utilized to evaluate the colony morphology. Quantitative Real-ime PCR(qRT-PCR) was adopted to observe the expression of hyphae-specific genes such as HWP1, ALS3, UME6, CSH1, SUN41, CaPDE2.

RESULTEAHD with concentration of 312 and 1 250 mg . L-1 could inhibit formation of hyphae and colony morphology. The expression of HWP1, ALS3, UME6, CSH1 were downregulated 4. 13, 3. 64, 2. 46, 2. 75 folds ,while the expression of SUN41 were upregulated 7. 26 folds, CaPDE2 keep unchanged.

CONCLUSIONEAHD could inhibit formation of hyphae and colony morphologies of C. albicans through downregulating HWP1, ALS3, UME6 and CSH1.
