Objective To evaluate CT manifestations and its clinical significance of the laryngopharyngeal carcinoma.Methods CT findings of 18 cases with laryngopharyngeal carcinoma proved by surgery and pathology were analysed.Results Of 18 cases,11 cases were in the piriform fossa,5 cases were in the postcricoid region and 2 cases were in the posterior wall of laryngeal pharynx.The tumor showed isodense or mixed density and slightly enhancement.It was the characteristic feature of the laryngopharyngeal carcinoma that the tumor pushed the annular and arytenoid cartilage displacement anteriorly,the thyroarytenoid gap and cricothyroid joint were widened.Other indirect findings included invasion of the larynx and esophageal ostium,destruction of laryngeal cartilage and metastasis of lymph node of neck.Conclusion CT can reliably exhibit the location,size and extent of the tumors and metastasis of lymph node of neck.It is useful in working out the thearapeutic program and evaluating prognoses.

OBJECTIVE: To raise awareness of granulomatosis with polyangiitis by summarizing its nasal mani- festations and treatment experience. METHOD: Retrospective studies were done to the nasal clinical manifestations and treatment processes of 21 GPA patients in this study. All were treated by the combined treatment of glucocorticoid, cyclophosphamide as well as tripterygium wilfordii, and 4 of them who had much heavier nasal symptoms were treated by endoscopic sinus operation at the same time. RESULT: Eighteen cases were effective treated by medical treatments besides 3 were died of all 21 cases. The nasal symptoms of those 4 patients were obviously improved, and still had effective drainage of sinus after operation with 8-22 months follow up, although the sinus ostiums were reduced comparing to themselves intraoperation at different degree. CONCLUSION GPA is always been ignored which will lead to delay treatment due to the lack of specificity of its clinical manifestations. So, enough attention is the key point of avoiding misdiagnosis as well as providing timely treatment for these patients.

Patient, 30-year-old, male,was admitted to our hospital because of discontinuously spit fresh blood without any inducing factors for three days. In the course, the patient suffered mild dry sensation of pharyngeal, poor spirit condition, fatigue, poor sleep, poor appetite and was with black stool 2 times. Physical examination: T36. 6°C, R 21/min, P98/min, BP135/90 mmHg (1 mmHg = 0.133 kPa). Bilateral tonsils were III hypertrophy and with scar shape surfaces. The left tonsil's surface had longitudinal small blood vessels markedly dilated. His oropharynx, laryngopharynx and laryngeal did not be find any obvious bleeding sites. Laboratory findings: WBC 13.82 x 10(9)/L, N 0.8084, L 0.1632, Hb 81.00 g/L, HCT 25.20; PT 9.60 s, APTT 25.50 s, TT 15.80 s, FIB 1.900 g/L. After 3 hours of admission,the patient spit out fresh blood again,checked the body to see:the left peri-tonsil with fresh blood and found a slowly bleeding site at the 1/3 junction of the middle lower part of left tonsil's rear surface, the size was about 0.5 cm x 0.6 cm. We finally diagnosed spontaneous tonsillar hemorrhage and successfully managed with low-temperature radiofrequency technology.

Objective To observe the clinical efficacy ofWuzi Yishen Oral Liquid for female stress urinary incontinence.Methods Ninety patients were randomized into treatment group (45 cases) and control group (45 cases). The treatment group was treated byWuzi Yishen Oral Liquid, while control group was treated bySuoquan capsule. After three-month treatment, the clinical efficacy was observed by 1 h pad-test and urinary incontinence questionnaire scores.Results Compared with before treatment, the quantity of fluid loss of 1 h pad-test of the two groups was reduced significantly, and the symptom scores of urinary incontinence questionnaire were improved after treatment (P<0.05). The symptom scores of urinary incontinence questionnaire of the treatment group were higher than the control group (P<0.05).ConclusionWuzi Yishen Oral Liquid has obvious clinical efficacy for the treatment of female stress urinary incontinence.

Objective To explore the therapeutic effects of isokinetic eccentric exercise (IEE)in patients with knee osteoarthritis. Methods Forty patients, including 70 knees with osteoarthritis, were measured and trained by use of Cybex-6000 and its isokinetic exercise system 3 times per week for 4 weeks. The peak of moment, single largest work, average power and accelerate energy of moment of isokinetic speed in 60?/s、120?/s and 180?/s were measured before and after exercise. The scores of pain and lower limb function were compared before and after IEE. Results The parameters of extensor and flexor groups were significantly increased after exercise, especially the parameters of knee flexors. The scores of pain and lower limb function were also improved. Conclusion IEE could improve effectively the function of knee extensors and flexors in patients with knee osteoarthritis, and relieve the pain.

Polymerase chain reaction(PCR) was used for the first time in China for the diagnosis of cryptococcal meningitis by amplification of specific sequence of the rDNA genes of C.neoformans.All 11 strains of C.neoformans yielded a specific 136 bp fragment but 21 non-C,neoformans strains did not. The sensitivity of the amplification was about 10 cfu.With the aid of the rDNA-PCR,23 of the 23 cere- brospinal fluids (CSF) specimens which had been confirmed C.neoforrnans positive by smear and/or cul- ture were PCR-positive(100%),and 13 of the 14 CSF specimens which had been confirmed C.neofor- mans negative by smear and culture were PCR-negative (93%).The results of the present study suggest that rDNA-PCR is a sensitive and specific method for rapid diagnosis of cryptococcal meningitis.

At present, the teaching management department is facing a big puzzle in the education of medical professional postgraduate degree. How to strengthen the appropriate scientific research training while successfully completing the 33-months clinical rotation. With the social development and increasing demands, the original training model that training professional technical personnel and scientific academic personnel seperately has been confirmed unable to adapt to the current requirements. Combining with the practi-cal experience of the medical postgraduate degree education, we put forward some constructive suggestions of boosting the innovation of the medical postgraduate degree education from several aspects, such as optimizing the training process, strengthening the stage man-agement, improving the quality of the tutor team, smoothing the communication mechanism between teachers and students, cultivating clinical research thinking, etc.

Objective To investigate the methods and effects of abdominal and pelvic shielding for pediatric chest CT examinations.Methods The 705-D phantom made by Computerized Imaging Reference Systems (CIRS) was used to replace a 5-year-old child,thermoluminescent dosimeters were set in the abdomen and pelvis to measure the organ and tissue doses.Chest scans were conducted with the routine protocol for pediatric chest CT examinations.Doses to main organs and tissues in the abdomen and pelvis were measured after chest CT scans without lead apron,with lead apron covering anterior of the abdomen and pelvis and with apron wrapping same part,respectively.Results Absorbed doses to some abdominal organs near the irradiation field were up to several mGy in a procedure of pediatric chest CT examination.There were statistically significant differences among the dose values for three different scans at the same location (x2 =16.00,P ＜ 0.05).Statistically significant difference was also found between the dose values for scans,which were measured with wrapping and covering approaches (Z =-2.52,P ＜ 0.05).Compared to the doses in the condition of no shielding,the doses in testis and colon reduced by 71.2％ and 42.3％,respectively,if the abdomen and pelvis was wrapped with a lead apron (0.35 mm Pb),and reduced by 55.9％ and 26.1％,respectively,if the same lead apron was used to cover the anterior of the abdomen and pelvis.Conclusions In pediatric chest CT examinations,the use of a lead apron can effectively shield the abdomen and pelvis,and plays an important role in protection of the gonad and colon.The wrapping measure is worth being recommended.

ObjectiveThis study was to evaluate the effects of different pneumoperitoneum used in laparoscopy on in vitro tumor cells growth. Methods 3H-TdR incorporation was used to compare the DNA synthesis (CPM value) of tumor cells after exposure to simulated laparoscopic environments, composed of carbon dioxide, helium and room air, respectively. Results At 24 hours after pneumoperitoneum, compared with group of helium, air and control, CPM increased in group of carbon dioxide (F=47.576 5,P0.05). At 48,72 and 96 hours, pneumoperitoneum, compared with helium group, air group and control group, CPM increased significantly in carbon dioxide group (F=116.183,1082.92 and 5116.75, P0.05). Conclusion Carbon dioxide promotes tumor cells growth, while helium restrains the growth of tumor cells. [
