To analyze the clinical characteristics,imaging and pathological features of 1 case with partial right lung atelectasis and summarize the relevant domestic reports on the false positive of positron emission tomography-computed tomography (PET-CT) and tumor markers.The patient was diagnosed by PET-CT as partial atelectasis and there were progressive increases of CEA,CA199 and CA242.But site of lesion biopsy showed no malignancy.After treatments of anti-inflammatory and eliminating phlegm,the tumor markers returned to normal and the lesion site had excellent re-expansion.The detection of PET-CT plus tumor markers may have false positive probability.The reason is probably related with inflammation and glandular secretion of lesion site.

Objective: To revise the Chinese version of Father-Child Relationship Scale(FCRS) and to examine its reliability and validity. Methods: Data were collected with Child-Parent Relationship Scale based on a sample of 400 young children and their fathers,retest was given after a month,and follow-up study was carried out to 106 children for 9 months. Results: The results of Confirmatory Factor Analysis showed a good fit to the data,and the examination of its criterion-related validity,by using children's behavior problems and social competence as criterions,also indicated that both the concurrent and the predictive validities of FCRS were satisfactory. The internal consistency reliability of FCRS was satisfactory,with Cronbach ? coefficient 0.71; and the test-retest reliability was also satisfactory,with test-retest correlation coefficient 0.68(P

For more than 40 years primary hepatocytes culture technique has been utilized extensively for assessing effects of drug on metabolizing enzymes (especially cytochromes P450), drug metabolism, drug-drug interactions, and the mechanisms of cytotoxicity and genotoxicity. Human derived primary hepatocytes reserve the metabolism function and enzyme activity of liver. Therefore, this technique has been widely used as a reliable and efficient tool in the drug and xenobiotics evaluation and screen in vitro. This review focuses on primary culture technique of hepatocytes and its application in drug metabolism and toxicology research and evaluation.

Objective To explore the effect of vaginal pressure feedback combined with pelvic floor muscle resistant training on stress urinary incontinence (SUI). Methods 125 women with SUI in our hospital from February, 2014 to May, 2015 were randomized into control group (n=65) and experimental group (n=60). The control group took Kegel exercise, which asked for patients to contract their pelvic floor muscles, while the experimental group first received biofeedback electrical stimulation for 20 minutes with XFT-2002 pelvic floor stimula-tor, then instructed the patients to contract their pelvic floor muscles and pressed the pneumatic probe which placed in vagina according to the voice navigation of XFT-0010 pelvic floor muscle stimulator after they learnt the contraction skill. Both groups received training with 10 seconds' contraction and 10 seconds' rest 30 minutes per day for 30 days in total. They were assessed by GRRUG and International Consulta-tion Incontinence Questionnaire-UI Short Form (ICIQ-SF). Results After treatment, the muscle strength of the pelvic floor (t=-3.570) and the scores of ICIQ (t=4.198) improved significantly in both groups (P<0.01), and was higher in the experimental group than in the control group (t=6.833, t=-2.445, P<0.01), as well as the therapeutic efficiency (Z=63.954, P<0.001). Conclusion Vaginal pressure feedback com-bined with pelvic floor muscle resistant training can further improve stress urinary incontinence in women.

Objective To investigate the effects of surface anesthesia on assisted balloon dilatation when treating dysphagia caused by radiotherapy for nasopharyngeal carcinoma.Methods Fifty-four patients with dysphagia after radiotherapy were divided randomly into an anesthesia group and a non-anesthesia group.The anesthesia group received anesthetics before treatment while the non-anesthesia group did not.All of the patients were treated with low-frequency electrical stimulation and assisted balloon dilatation for 3 weeks.They were then assessed using videofluoroscopy and self-reports of difficulty in swallowing before and after the treatment.Results After the treatment, significant improvement was observed in pharyngeal delay time, in cricopharyngeal opening, and in laryngeal elevation and forwardness.There was also a significant decrease in self-reported swallowing difficulty and failed swallows in both groups compared with before the treatment.The improvements in the non-anesthesia group were significantly greater than in the anesthesia group.After the treatment, the average aspiration rate of the anesthesia group was significantly higher than before treatment and higher than that of the non-anesthesia group.The improvement in oral intake of the non-anesthesia group was significantly better than that of the anesthesia group.Conclusion Balloon dilatation and low-frequency electrical stimulation have a synergistic effect and can improve patients' swallowing after radiation-induced cranial nerve damage, thus promoting survival.Assisted balloon dilatation without anesthesia has a better effect than when surface anesthesia is used.

Seventy-five preschool children with hemoglobin content below 11 g/dl in kindergartens and nurseries were divided into five groups. The first, second and third groups were given 10 mg, 20 mg and 30 mg of iron in the form of ferrous sulfate syrup respectively every day for two months, while the fourth and fifth groups were given 100 mg ascorbic acid and 100 mg ascorbic acid plus 10 mg iron respectively every day for one month. The average hemoglobin content in the order of the five groups were 9.6?1.16, 10.6?1.34, 9.7?0.91, 9.7?0.85 and 11.0?1.86 g/dl respectively before treatment. After 1-2 months of iron or ascorbic acid therapy, the average hemoglobin contents raised to 12.0?.31, 12.0?1.06, 12.0?0.79, 11.0?1.86 and 12.7?1.37 g/dl respectively. There were highly significant differences (P

Objective: To evaluate the relationship between bolus volume and hyoid displacement in dysphagia patients with nasopharyngeal carcinoma after radiation therapy. Methods: Twenty-three nasopharyngeal carcinoma patients with dysphagia were recruited and their swallowing of 3, 5, 10 and 20ml of liquid food was studied fluoroscopically. The vertical and horizontal displacement of the hyoid as well as its time in motion were measured, and the relationship between the bolus volume, hyoid displacement and time in motion time was evaluated. Results: The largest vertical displacement of the hyoid (1.01±0.65cm) was observed when swallowing a 10ml bolus. The hyoid showed the smallest average horizontal displacement (0.39±0.34cm), when swallowing a 3ml bolus. The average motion time of the hyoid was (2.11±0.65) seconds. It was shorter when swallowing a 10 or 20ml bolus than when dealing with a smaller one. Hyoid motion time was negatively correlated with the horizontal displacement of the hyoid bone, and the volume of a swallow was negatively correlated with the hyoid motion time but positively correlated with the penetration-aspiration scale score. Conclusion Bolus volume affects hyoid displacement and hyoid motion time in nasopharyngeal carcinoma patients with dysphagia after radiation therapy. For patients with a penetration-aspiration scale score of 5 or less, the optimum bolus volume is 5 to 10ml.
