OBJECTIVE:To study the stability of omeprazole in micro-pump by continuous administration.METHODS:RP-HPLC were used to determine the concentrations of omeprazole at different times in micro-pump after administrcotion24h by simulating the dose mode in clinical.RESULTS:Omeprazole for injection was stable in6h after administration.CON?CLUSIONS:The time of taking omeprazole via micro-pump should be controled in6h.

Based on the lethal rate, positive and negative mutation rate, the optimal doses of UV, HNO2, UV + AO treating S. hygroscopicus NND-52-29 were determined. The mutant strain A19 that was obtained showed the derepres-sive property to glucose and the nigericin yield of A19 could be increased by 128%. When it was subcultured combined with natural screening, its stability was rather satisfied.

Objective To study the imaging features regarding perineural spread of tumor along the trigeminal nerve in malignant head and neck tumors, investigate its usefulness in improving diagnostic accuracy and palnning for clinical treatment. Methods Images in 9 patients with clinical or radiological findings suggestive of perineural spread along trigeminal nerve were retrospectively studied. Results Among the 9 patients, 6 were adenoid cystic carcinoma of the hard palate (n=3), maxillary sinus (n=1), parotid gland (n=1) and buccal space (n=1), respectively. Two were nasopharyngeal carcinoma and 1 was squamous carcinoma of the maxillary sinus. Enlargement and fat effacement of greater palatine foramen and pterygopalatine fossa distant from primary diseases were seen in all the 3 patients with adenoid cystic carcinoma of the hard palate and 1 with squamous carcinoma of maxillary sinus, furthermore, enlargement of foramen ovale and invasion of meckal cave was seen in 1 case. Erosion of infraorbital foramen and enlargement of the pterygopalatine fossa was seen in 1 patient with adenoid cystic carcinoma of maxillary sinus. Enlargement of pterygopalsatine fossa and foramen rotundum and invasion of the Meckal cave were seen in 1 patient with adenoid cystic carcinoma of buccal space. Perineural spread along auriculotemporal nerve and intracranial invasion through foramen ovale were seen in 1 patient with adenoid cystic carcinoma of parotid gland. Enhancement of mandibular nerve was seen in 2 patients with nasopharyngeal carcinoma. Conclusion Perineural tumor spread along trigeminal nerve can be seen in malignant head and neck tumors, and knowledge of the anatomy of trigeminal nerve and its surrounding structures is important for correct diagnosis.

Objective:To explore the influential factors of cognitive change among Chinese oldest-old.Method: Three waves of data from the Chinese Longitudinal Healthy Longevity Survey(CLHLS)were analyzed with a two-level repeated measures model.Results:In baseline,the male had a higher mean MMSE score than the female(27.0?3.7/24.4?5.6,P

Prostate cancer, bladder cancer, and rectal cancer are common malignancies in the male pelvis. The incidence rate of erectile dysfunction (ED) following radical prostatectomy, cystectomy or rectal cancer surgery is about 25% - 100%. The main cause of post-surgery ED is mainly attributed to injury of neurovascular bundles, which may lead to reduced oxygenation in and fibrosis of the penile tissue. Early penile rehabilitation after surgery can improve or restore the erectile function of the patients. This article focuses on penile rehabilitation after radical pelvic surgery.

Oral sustained- and controlled-release drug delivery systems of traditional Chinese medicine (TCM) are a research hotspot in the development of drug-delivery systems for TCM. The quality evaluation system is an important guarantee for the safety and efficiency of these drug-delivery systems. In this paper the methods to construct such quality evaluation system were discussed.

Objective To investigate the level of serum angiopoietin-like protein 4 (ANGPTL4) in normal subjects and patients with obesity and newly-diagnosed type 2 diabetes mellitus (T2DM),and to explore the relationship of serum ANGPTL4 with parameters of body fat,glucose-lipid metabolism,and insulin resistance index (HOMA-IR).Methods A total of 160 subjects with normal glucose regulation(NGR) and newly-diagnosed T2DM,were divided into 4 groups:NGR with normal weight group (NGR-NW),NGR with overweight/obese group (NGROW/OB),T2DM with normal weight group (T2DM-NW),and T2DM with overweight/obesity group (T2DM-OW/ OB) according to their body mass index(BMI).ELISA was used to determine the level of serum ANGPTL4.The weight,height,waist circumference,hip circumference,waist hip ratio(WHR),and BMI,fasting insulin(FINS),lipid metabolism parameters,and insulin resistance index (HOMA-IR) were measured.Results Compare with the NGR group,the level of ANGPTL4 was significantly decreased in the T2DM group [(25.75 ±2.85 vs 31.08 ±3.35)ng/ml,P＜0.01],the level of ANGPTL4 in OW/OB group was significantly lower than that in the NW group [(27.27± 3.05 vs 29.04 ± 4.64) ng/ml,P＜0.01].Partial correlation analysis showed that serum ANGPTL4 was negatively correlated with BMI,WHR,FPG,2hPG,HbA1C,FINS,HOMA-IR,AST,ALT,and TG levels(P＜0.01),but positively correlated with the HDL-C(P＜0.01).Multiple stepwise regression analysis showed that HbA1C,FINS,and HDL-C were independent risk factors of serum ANGPTL4 (β =-0.825,-0.119,3.301,P＜0.01).Conclusion Serum ANGPTL4 level in T2DM and OW/OB group was lower than that in NGR and NW group.Serum ANGPTL4 is associated with FINS and lipid metabolism,suggesting that it may play an important role in the pathophysiology of obesity and metabolic syndrome.

Objective To investigate the CT features of the invasion of sublingual space by malignant oropharyngeal tumors in order to provide more accurate information for clinical treatment. Methods Fifty-eight cases of pathologically proven malignant oropharyngeal tumors were collected and retrospectively analyzed. Results Among all the cases, invasion of sublingual space by malignant oropharyngeal tumors could be seen in 14 cases, of which, 7 cases got access to sublingual space through tongue base, 3 cases through parapharyngeal space, 2 cases through pterygomandibular raphe, 2 cases through uncertain routes. Invasion of sublingual space manifested on CT scan as obliteration of fat plane in sublingual space and involvement of the sublingual vessels in the space. Conclusion Malignant oropharyngeal tumors can invade the adjacent sublingual space via tongue base, pterygomandibular raphe, and parapharyngeal space. The invasion of sublingual space by malignant oropharyngeal tumors manifests in CT as effacement of sublingual fat plane and envelopment of hyoid artery.
