OBJECTIVETo develop a quality of life scale for patients with congenital external and middle ear malformation, and to explore its reliability and validity.

METHODSThe initial quality of life scale for patients with congenital external and middle ear malformation was constructed based on quality of life scales from home and abroad. A total of 140 patients with congenital external and middle ear malformation had been recruited in the study. After pretest and item sifting, the quality of life scale was constructed, and its reliability and validity were evaluated.

RESULTSEighteen-item quality of life scale for patients with congenital external and middle ear malformation was constructed, which included three parts: physiological function, psychological status and social interaction. The retest reliability was 0.878; split-half reliability coefficient and Cronbach's alpha coefficient were 0.927 and 0.899, respectively. The results of factor analysis showed satisfactory construct validity. The reliability and validity of this scale was consistent with the demands of psychometrics.

CONCLUSIONCongenital external and middle ear malformation quality of life scale is believable and effective, which can be used for clinical practice.

OBJECTIVETo evaluate the feasibility and efficacy of enteral nutrition (EN) in patients underwent open-abdomen managements.

METHODSTwenty-one patients who received at least 3 days of EN after opening the peritoneal cavity between January 2003 and November 2006 were included in this study. Energy expenditure and actual caloric and protein intake were determined in some patients. The levels of serum protein and nitrogen balance before and after the EN were analyzed. Other related complications were also evaluated.

RESULTSAverage daily total caloric intake was 93% - 95% of estimated needs. The EN support was administered (8.8 +/- 5.5) d after opening the abdominal cavity and lasted for (51.5 +/- 33.6) d. Initial serum protein levels were low and below normal but increased in all of the patients after the EN. The average nitrogen balance was (-28.6 +/- 5.4) g/d. Diarrhea, gastric reflux, vomiting and abdominal distention occurred in 67%, 23%, 9.5% and 23% of the patients, respectively. All the complications were managed well.

CONCLUSIONSEN support could be effectively and safely given in patients requiring opening peritoneal cavity management.

The chemical shift of fluoxetine hydrochloride appears at delta 14.15 in 19F NMR analysis. The delta moved upfield slightly from 14.158 to 14.145 when the concentration of solution became diluted from 2.00 to 0.05 mmol x L(-1). Spiking test was suggested to confirm the existence of the compound for qualitative analysis. 19F NMR detection sensitivity test illustrated that a concentration of 17 mg in 1 L water could be detected while the sample was scanned 500 times with optimum parameters. In quantitative analysis, standard curve of concentration versus fluorine signal intensity was proposed to determine the amount of fluoxetine. Long capillary tube containing trifluoroacetic acid was used as internal standard for the integration measurements and straight line was obtained with good fitting. Direct additions of trifluoroethanol to fluoxetine solutions gave a poorer standard curve.

OBJECTIVETo research the effects of chronic suppurative otitis media on bone conduction threshold in old patients.

METHODSThe files of patients with unilateral chronic otitis media were retrospective analyzed, who were all oder than 60 years, who were inpatient in our department since January 2005 to March 2009. Conventional puretone audiometry test was carried out. Bone conduction thresholds were calculated for frequencies of 0.5, 1, 2, and 4 kHz, with comparison between the ear with chronic otitis media and contralateral ear. Thresholds were examined separately for each frequency.

RESULTSThe bone conduction threshold for the normal side was lower than those for the ear with chronic otitis media. The threshold shift was statistically significant for each frequency (P < 0.01). There were no differences between the groups when analyzed for the presence of cholesteatoma except at 2 kHz frequencies (Z = -1.975, P = 0.048). There were differences between the groups when analyzed for an interruption of the ossicular chain only at 2 kHz frequencies (Z = -2.721, P = 0.007). There were differences between the groups when the duration of middle ear disease was not same at 1 kHz and 2 kHz frequencies (Z value were -2.877, -2.624, P < 0.01, respectively).

CONCLUSIONSThis study shows that chronic otitis media can enhance bone conduction threshold for old patients. All measures for early cure should be considered as early as possible in oder patients with chronic otitis media to prevent advance of sensorineural hearing loss.

AIMTo study the antidiabetic effects of cortex Moutan polysaccharide-2b (CMP-2b) in type 2 diabetes mellitus (T2DM) rats.

METHODSThe T2DM model rats were induced by a single intravenous injection of low dose streptozotocin (STZ) and intake of high sucrose-fat diet. CMP-2b was given to T2DM rats daily through gavage for 4-5 weeks. The body weight, water and food intake, fasting blood glucose (FBG), glucose tolerance, plasma lipids, serum insulin, and insulin receptor (Ins R) were determined.

RESULTSOral administration of CMP-2b significantly decreased water and food intake, FBG, total cholesterol (Tch), and triglyceride (TG), improved the impaired glucose tolerance (IGT), and remarkably raised the number of low affinity InsR and insulin sensitivity index (ISI) in T2DM rats.

CONCLUSIONCMP-2b may be useful for treating T2DM and its complications.

Objective Clinical data of 19 Chinese patients with 21 hydroxylase deficiency (21OHD) were analyzed to improve the diagnosis and treatment level. Methods Clinical features and laboratory data were collected from 19 patients with 21OHD before and after treatment. Results In male patients, the average age of early appearance of secondary sexual character was (9.3?2.8)yrs, and excess androgen resulted in phallic enlargement. Primary amenorrhea was the most common complaint in female(87.5%), and the signs included a varying degree of labioscrotal fusion and clitoral enlargement. The average level of 17-hydroxy progesterone(17OHP) was (63.42?35.07) ?g/L, and adrenocorticotrophic hormone(ACTH), dehydroepiandrosterone(sodium) sulfate(DHEAS) and testosterone(T) were obviously elevated. CT scan showed bilateral adrenal hyperplasia. The level of 17OHP was significantly decreased after treatment[(63.42?35.07) ?g/L vs (3.15?2.71) ?g/L](P

The borneol was included with β-CD and prepared Fufang Danshen intestinal adhesion pellets. GC method for determination of borneol in Fufang Danshen intestinal adhesion pellets was established to study its in vitro dissolution and make a comparison with the Fufang Danshen tablet, in this way, the rationality of dosage form was evaluated. The first method of dissolution determination was used for determining the in vitro dissolution of borneol in Fufang Danshen intestinal adhesion pellets in artificial intestinal juice, and Fufang Danshen tablet in artificial gastric juice and intestinal juice, respectively. Result shows: the concentration of borneol in Fufang Danshen intestinal adhesion pellets and Fufang Danshen tablet was 0.79% and 0.80%, respectively. Its in vitro dissolution was nearly 70% within 12 h in Fufang Danshen intestinal adhesion pellets, and in Fufang Danshen tablet, the dissolution was about 60% within 20 min and more than 90% within 40 min, and in artificial gastric juice, was less than 20% within 40 min but more than 80% till 150 min. Research suggests that in comparison with Fufang Danshen tablet, in vitro dissolution of borneol in the Fufang Danshen intestinal adhesion pellets showed an obvious sustained release behavior. The borneol in Fufang Danshen intestinal adhesion pellets was included with β-CD and prepared enteric preparations. To some extent, the stimulation on stomach and intestinal mucosa can be reduced and safety can be improved.
