Objective To analyze the CT characteristics and misdiagnosis reasons in mass-forming intrahepatic cholangiocarcinoma(ICC)and liver abscess to reduce the misdiagnosis rate.Methods CT features of 21 patients with mass-forming ICC and 20 patients with liver abscess proved by operation or puncture pathology were analyzed,in which 10 cases of mass-forming ICC were misdiagnosed as liver abscess.CT plain scan and three period enhanced scan were performed in 41 cases.Results Irregular edge enhancement rings,irregular patch or flocculent strengthened in delayed phase,arterial through surrounded lesions,liver capsule shrinkage,tissue nodule in intrahepatic bile duct,intrahepatic bile duct dilatation,hilar and retroperitoneal lymph node enlargement,portal vein invasion stenosis or occlusion,which possibility prompted to be the diagnosis of mass-forming ICC.Regular shape,slippery and intact ring-wall,edema syndrome around the ring wall,separate and annulate enhancement in delayed phase,reduction of tumor size and similar low density liquid in ring hints prompted to be the diagnosis of liver abscess.Liver abscess appears abnormal perfusion likely and significant.Conclusion Mass-forming ICC sharing similar imaging characteristics with liver abscess,having characteristic CT features.A comprehensive analysis of multiple signs may be helpful to arrive at a correct diagnosis.

To investigate the effects of iron deficiency on cochlear structure and functions, an auditory electrophysiological and histopathological study was conducted in the rats which were fed with either a basic Fe-deficient diet or a standard diet.It was found in iron-deficient rats that the incidence of threshold elevation (more than 15 dB) in both auditory brain-stem response and electrocochleogram-N1Was 31.85%, and cochlear histopathological changes were stria atrophy and reduction of spiral ganglion cells. No change was found in the controls.These findings suggest that iron deficiency could be a direct cause of sensorineural hearing loss, or could provide a pathological basis for cochlear deafness.

Objective To study the effect of acupuncture and medication on plasma ealcitonin gene-related peptide(CGRP) levels in patients with acute cerebral infarction. Methods 90 patients with simple obesity were ran-domly divided into acupuncture and medication group( n = 45) and medication group( n = 45 ). All patients were ex-amined the plasma level of CGRP to observe clinical curative effect before and after 1 month treatment. Results The total effective rate of acupuncture and medication group 91.1% (41/45) was significantly higher than that in medication group 77.8 % (36/45) (P < 0.05) ; after treatment the plasma level of CGRP in two groups were signifi-candy higher than those before treatment(P < 0.05) , acupuncture and medication group was significantly higher than that in medication group (P < 0.05). Conclusion Acupuncture in combination with drug could cut down nerve cell damage, and it may be significantly related to levels of CGRP in patients with acute cerebral infarction.

ObjectiveTo discuss the diagnosis and treatment methods of endometriosis, so as to improve the diagnosis and treatment level. MethodThe clinical data of 236 patients with endometriosis was analyzed retrospectively, all the patients were treated with surgery and mifepristone. ResultOf the 236 patients, 69 to retain reproductive function routine surgery, the cure rate was 60.9％(42/69); 146 to retain ovarian function routine surgery, the cure rate was 58.9％(86/146); 21 to undergo radical surgery, 12 patients with menopause symptoms. ConclusionSurgical treatment with mifepristone in endometriosis can get better results.

About 40 % of testicular germ-cell tumours are seminomas, and most of them are clinical stage Ⅰ . For a long time, the standard treatment approach for stage Ⅰ testicular seminoma has been radical inguinal orchiectomy followed by radiotherapy to the para-aortic and ipsilateral pelvic lymph nodes. In recent years, many oncologists indicate that the effect of the adjuvant postoperative para-ortic lymph nodal irradiation and chemotherapy using carboplatin is equivalent to para-aortic and ipsilateral pelvic irradiation post orchiectomy for patients with Stage Ⅰ seminoma of the testis, and the side effects is obviously declined, but the long-term side effects are still indefinite. This review presents the treatment development of the stage Ⅰ testicular seminoma after radical inguinal orchiectomy.

Objective To compare the effect of adenoidectomy with adenoidectomy under nasal endoscope in the treatment of adenoid hypertrophy.Methods 120 cases with adenoid hypertrophy were selected as the research subjects.The patients were randomly divided into two groups by random number table,and the control group(n =60) was treated with routine adenoidectomy.The surgical treatment of the observation group(n =60) was performed under nasal endoscope.Surgical treatment,surgery related indicators (operative time,the average amount of bleeding,hospitalization time and the incidence of postoperative complications) were compared between the two groups.Before and after operation,acoustic rhinometry examination of nasopharynx was used to detect the smallest cross-sectional area and compared.Results In the observation group,the operation time,the average amount of bleeding,hospitalization time and incidence rate of postoperative complication were (5.32 ± 2.05) min,(51.05 ± 8.26) mL,(8.50 ± 2.50) d,15.00％,respectively,which in the control group were (8.56 ± 2.68) min,(78.45 ± 10.15) mL,(12.00 ± 3.50) d,36.67 ％,respectively,there were significant differences between the two groups (t =7.44,15.98,6.30,x2 =7.35,all P ＜0.05).12 months after surgery,the nasal minimal cross-sectional area of nasal pharynx in the observation group was (1.99 ± 0.51) cm2,which of the control group was (1.81 ± 0.48) cm2,there was significant difference between the two groups(t =3.99,P ＜ 0.05).Conclusion Compared with conventional adenoidectomy,endoscopic adenoidectomy in the treatment of adenoid hypertrophy has good clinical curative effect,less bleeding,shorter operative time and less postoperative complications and other advantages,it is worthy of promotion.

Objective To study MRI and CT manifestations and characteristics of primary intracranial lymphoma,and improve the diagnosis and differential diagnosis.Methods Imaging features of primary intracranial lymphoma in 1 1 patients proved by pathology were analyzed retrospectively.Results 9 cases were solitary tumor and 2 cases multiple lesions.Tumors were located in the frontal lobe in 2 cases,the corpus callosum 2 cases,near meningeal 2 cases,the occipital lobe 3 cases.Tumors presented as isodensity or slight hyper density on CT and equal or slight long T1 and T2 signal on MRI.All the lesions were found with obvious homogenous en-hancement;in which 2 cases were found meningeal strengthened;1 case room tube film strengthened.There were slight space occup-ing effect,mostly mild to moderate edema,severe edema in 2 cases.7 typical cases presented “umbilicus sign”,“notch sign”,“lobu-lated”,“incision sign (fist sign)”,and “half month”and so on.Conclusion Imaging manifestations of primary intracranial lymphoma has certain specificity and MRI plays an important role in making accurate diagnosis in the position and qualitative diagnosis.

Haemophilus influenzae (Hi)is an important human pathogen that causes severe infections inclu-ding meningitis,bacteremic pneumonia and sepsis,mostly affecting young children.The resistance of Hi to antimicro-bials has risen and wide variations exist in antibiotic resistance,both geographically and over time.The main mecha-nisms of resistance of Hi are those to β-lactam antibiotics.Antibiotic utilization is the main risk factors for the deve-lopment of antimicrobial resistance.Third -generation cephalosporins is the most effective antibiotic agent to treat the infections of Hi in children population.With continued research,progress toward a broadly effective vaccine to prevent infections caused by Hi is expected in the near future.

Objective To identify the posttraumatic growth (PTG) level of cancer patients and to examine the effects of rumination on posttraumatic growth of cancer patients.Methods A total of 312 cancer patients were recruited by convenience sampling.A cross-sectional study was conducted in cancer patient by means of questionnaires that included demographic scale,Event Related Rumination Inventory and the Posttraumatic Growth Inventory (PTGI).Results A total score of event-related rumination in cancer patients was 25.13±11.11,and the total score of posttraumatic growth was 67,21±14.66.The PTG was positively correlated to event-related rumination in cancer patients (r=0.384,P ＜ 0.01).Multiple stepwise regressions indicated that the variables of deliberate of rumination,gender,age,degree of psychological distress,intrusive rumination and education level were main predictors of PTG.Among those deliberate of rumination positively predicts PTG,while intrusive rumination negatively predicts PTG.The level of PTG in female gender cancer patients were higher than male patients,younger age and high education level,less psychological distress patients related to higher PTG.Conclusions Cancer patients reported a lower level of rumination and PTG.Clinical healthcare providers should inspire and promote cancer patients' deliberate rumination,decrease their intrusive rumination,pay attention to male,more psychological distress,older age and lower education level patients,in order to facilitate patients' PTG and then improve their quality of life.
