Objective To determine the occurrence and clinical characteristics of ectopic pituitary adenoma (EPA) in China.Methods The study are done by searching systematically and comprehensively on major Chinese and English medical literature databases and conference papers before 2015,which are only limited to collected,summarized,sorted and analyzed EPA cases that reported by Chinese authors in English or Chinese occurred in China.Results ① Among the 86 Chinese articles and 27 English articles related to ectopic pituitary adenoma (EPA) gathered by the author,except for cases that have been confirmed as repeated reports,a total of 73 EPA cases were found.Of 70 cases with complete data,31 were male cases,accounting for 44.29％;39 were female cases,accounting for 55.71％;the ratio is 1:1.3.The frequency of EPA occurrence according to the location of the lesion,from high to low in turn,was sphenoid sinus (31 cases,42.47％),nasopharynx (7 cases,9.59％),suprasellar region (7 cases,9.59％),clivus (5 cases,6.85％),followed by the third ventricle,sphenoid sinus/clivus,nasal cavity,and the temporal lobe of the brain,with the same incidence of 4.11％.According to the functional properties of EPA,the frequency of different secreting hormones adenoma was PRL-ma(21 cases,28.77％),NF-ma (21 cases,28.77％),ACTH-ma (15 cases,20.55％),GH-ma (10 cases,13.70％),TSH-ma (2 cases,2.74％) and FSH-ma (1 cases.1.37％).Three cases of EPA were uncertain in their property due to lack of information.The incidence of PRL and nonfunctional tumors was the highest,which was different from what was reported in other countries.Among them,one case of EPA was in pineal region and one in parapharyngeal space,which was even more rare and were never reported abroad.(② Except for 3 cases with incomplete medical records,15 out of 70 cases of EPA were accompanied by empty sella,accounting for 21.43％,among which 11 (73.33％) cases involved the sphenoid sinus,and 3 (20％) cases involved clivus.The sphenoid sinus and clivus cases together accounted for 93.33％.(③ 29 out of the 69 cases of EPA with complete record were invasive pituitary adenomas,accounting for 42.03％ and including 1 case of pituitary adenocarcinoma,which accounted for 1.45％.(④ All cases were treated with surgery as the first choice,and some of them were treated with radiotherapy or drug therapy.Conc lusion Ectopic pituitary adenoma is extremely rare.By the end of 2015,the total number of cases reported in China is only 73,which are mostly located in the sphenoid sinus,suprasellar region and nasopharynx.In the functional classification,the most common types are still PRL adenoma and nonfunctional adenoma as in situ pituitary adenoma.42.03％ of EPA adenomas are invasive.Surgical resection of EPA is the first choice and some cases can be treated with radiotherapy and drug therapy.

OBJECTIVE This study was conducted to analyze the underlying bacterial pathogens of the tonsils and adenoids in children with sleep-disordered breathing(SDB).METHODS The core tissue from the tonsils and/or adenoids of 163 SDB children was cultured aerobically. Of the 163 cases, 120 children underwent adenoidectomy and tonsillectomy simultaneously(A+T), 39 children underwent adenoidectomy(A) and 4 tonsillectom(T) only. 124 children who underwent tonsillectomy were subdivided into two groups based on history(with or without a history of recurrent tonsillitis). 71 children with the history were enrolled in the 'recurrent tonsillitis group' and 53 children without the history were enrolled in 'non- recurrent tonsillitis group'.RESULTS Of the total 120 cases who underwent A+T, 114(95.00%) cases had same distribution of bacteria detected in both sides in the same patient. Besides this, 17 cases in whom mixed organisms were identified in both sites shared common pathogen. No significant difference in the detection rates of staphylococcus aureus and haemophilus influenzae were found when we compared seasons(Tonsil:χ2=8.538,P=0.201; Adenoid:χ2=5.427, P=0.490). No significant difference in the type and detection rate of essential bacteria was found when we compared between recurrent tonsillitis group and 'non-recurrent tonsillitis group' (χ2=3.028,P=0.387).CONCLUSION The bacterial isolates from the tonsils and adenoids are virtually identical in type and detection rate in the same SDB patient. The bacterial distribution of the tonsillar and adenoidal core is unaffected by the seasonal variation and history of recurrent tonsillitis.

OBJECTIVE To investigate the value of rigid bronchoscope combined with fiber bronchoscope application in children with airway obstruction.METHODS Retrospective analysis of 176 cases children with airway obstruction from January 1, 2006 to January1, 2016, all patients were diagnosised and treated in our hospital. RESULTS All children were acceptted rigid bronchoscopy combined with fiber bronchoscope under general anesthesia, then received the different thrapy according to the different causes. 104 patients with airway foreign body were all obtained satisfactory effect, 2 cases of children with bronchial foreign body(cap) inspection, failed to remove and contact thoracic surgery doctors to remove the foreign body by thoracotomy. 10 plastic bronchitis patients improved after treatment or cured. 7 cases of bronchial tuberculosis were cured after treatment. 4 patients with airway tumor after minimally invasive surgery, obtained good effect, 2 cases were turned to the other cancer hospital. 2 cases of patients with tracheal stenosis, the symptom is reduced after expansion. Bronchial granulation, tracheomalacia, bronchial softening, bronchial atresia patients improved after treatment. This group of all patients with pneumonia were cured after symptomatic treatment.CONCLUSION Rigid bronchoscopy and fiber bronchoscope are both useful for diagnosis and treatment of children with airway obstruction, both have its advantages and disadvantages, combined application can improve the accuracy of disease diagnosis and timely intervention on the patients.

Objective To investigate the safety and efficacy of mechanical thrombectomy (MT) compared with In?tra-arterial Thrombolysis (IAT) treatment in patients with severe acute ischemic stroke (AIS) caused by large cerebral ar?tery occlusion. Method The patients with AIS caused by large cerebral artery occlusion and underwent MT or IAT from 2005 May to 2014 May was included. A retrospective analysis was conducted on the onset to emergency(OTE)time, emergency to acupuncture(ETA)time, acupuncture to recanalization (ATR) time, stroke severity as measured by the Na?tional Institutes of Health Stroke Scale (NIHSS) score, and site of arterial occlusion on magnetic resonance angiography (MRA). A comparison was made between MT and IAT patients in rates of recanalization, symptomatic intracranial bleed?ing (SIB), mortality, and functional outcome. Three-month favourable outcome was defined as a modified Rankin Scale (mRS) score≤2. Result One hundred and two AIS patients were treated with MT and 50 with IAT. There was no differ?ence between MT and IAT groups with regard to demographics, onset NIHSS score (13.37±6.95 vs. 12.70±6.11;P=0.572) and discharge NIHSS score (8.40 ± 6.69 vs. 7.53 ± 7.28, P= 0.522) and the change of NIHSS score (3.87 ± 7.14 vs. 4.26 ± 5.42, P=0.766). There were significantly differences between MT and IAT groups in the OTE time (Median 300 min vs. 120 min,Z=-5.704,P=0.000) , ATR time (Median 30 min vs. 65 min,Z=-5.011,P=0.001) ,recanalization (91.2%vs. 60.0%,P =0.01),the rate of AIB(21.7% vs. 36.0%,P =0.046),3-month mortality (16.6% vs. 26.0%,P =0.043). The above parameters were better in MT group than in the IAT group. There were no significant differences between MT and IAT groups in the rate of SIB (12% vs. 16%,P =0.055), the NIHSS change(Median 3 vs. 4,Z =-0.236,P =0.823) and mRS score on 90d ( 48.2%vs. 46.0%, P=0.823). MT patients had significantly higher percentages of stent use (22.5%vs. 8%,P=0.018) . The Recanalization for ICA(81.8%vs. 55.6%,P=0.048),BA(93.1%vs. 55.6%,P=0.032)and MCA( 97.5% vs. 60.0%,P =0.026)was higher in MT group than in IAT group .The SIB rate for ICA(13.8% vs. 33.3%,P =0.000),BA(13.8%vs. 33.3%,P=0.000)was lower in MT group than in IAT group . The mortality rate of was significant?ly lower in MT than in IAT group for MCA (2.5%vs. 20.0%,P=0.000) . the good outcome rate for BA was higher in MT group than in IAT group(41.3%vs. 22.2%,P﹤0.01). Conclusions Compared to IAT,MT can provide broader time win?dow,higher recanalization rate and better outcome in patients with severe acute ischemic stroke (AIS) caused by large ce?rebral artery occlusion.

Objective To analyse the correlation between tone burst auditory brainstem response (tone burst auditory brainstem response,tb-ABR) and CE-Chirp voice evoked auditory steady-state response (auditory steady-state response,CE-Chirp ASSR) in infants with profound sensorineural hearing loss.Methods A total of 45 infants with profound sensorineural hearing loss underwent threshold tone burst ABR and CE-Chirp ASSR of the frequency response test,response thresholds were recorded in 0.5,1.0,2.0 and 4.0 kHz.Whether there was correlation or not existed between two methods were analyzed,SPSS 11.0 statistics software was used.Results Tone burst ABR and CE-Chirp ASSR could lead to different degrees of threshold in each frequency.Response e elicited threshold percentage mainly concentrated in the 91-100 dBnHL,correlation coefficient between 500-4 000 Hz response threshold elicited rate were:0.837,0.913,0.909,and 0.919,respectively (P ＜ 0.001).The difference of the frequency response threshold test between CE-Chirp ASSR and tone burst ABR were not significant (P ＞ 0.05,Chi square).Conclusions The tone burst ABR and CE-Chirp ASSR each frequency have different levels of residual hearing in infants with profound sensorineural hearing loss diagnosed by Click ABR,good correlation exists between tone burst ABR and CE-Chirp ASSR.

Objective To investigate the clinical application of the coblation in the treatment of the infant with sleep-disordered breathing. Methods The clinical data were reviewed from 161 infants, who had the cobtilaon tonsillectomy and/or adenoidectomy sugeries in our hospital from January , 2008 to June, 2012. Among the 161 SDB cases, there were 85 obstructive sleep apnea hypopnea syndrom cases and 76 primary snoring cases. After 12 months, the follow-up visit is cut off in January, 2013. Successful follow-ups had been done to 161 infant with SDB. And the clinical efficacy and the occurrence of the complications were investigated. Results the intra-operative blood loss was 10 mL or less. 2(1.24%) were delayed hemorrhage with less pain afteroperation. One year after the surgery, there were 141 cured (87.6%), 15 with apparent effects (9.3%), 3 with effective results (1.9%), 2 with no effect(1.2%)and the total effective rate is 98.8%. Conclusion It is minimally invasive, safe and effective to use coblation to remove tonsil and adenoid in the treatment of infants with sleep-disordered breathing.

OBJECTIVE: To explore the characteristics of post-operative pain following coblation tonsillectomy and/or adenoidectomy in children with sleep-disordered breathing (SDB) and explore the correlation between the first day post-operative pain scores and age and operating time. METHOD: 1) A total of 113 SDB children scheduled to undergo coblation tonsillectomy and/or adenoidectomy were recruited. 113 children were divided into two groups according to the method of operation, children who underwent coblation tonsillectomy and adenoidectomy were enrolled in study group one and children who underwent coblation adenoidectomy only were in study group two. Be sides, children of study group one with a history of chronic tonsillitis were in chronic tonsillitis group, children without a history of chronic tonsillitis were in non-chronic tonsillitis group. 2) The parents scored pain in their children on a VAS (anchored by "no pain" at 0 and "worst pain" at 10) in the morning, before using any analgesics and having breakfast, over the first 3 and the seventh post-operative days. 3) Post-operative pain scores were compared between both the study group one and two and chronic tonsillitis group and non-chronic tonsillitis group. Futhermore, the correlation between the first day post-operative pain scores and age and operating time were also analysed. RESULT: 1) The difference of post-operative pain scores over the first 3 and the seventh post-operative days were significant between the study group one and group two (P<0.05). 2) Non-chronic tonsillitis group were significantly less painful than chronic tonsillitis group on day 1, day 2 and day 7 (z=-2.004, -2.059, -2.334, P<0.05). But there was no significant difference in pain levels on day 3 (P>0.05). 3) The first day post-operative pain scores was correlated with age (r=0.273, P<0.01) and operating time (r=0.423, P<0.01). CONCLUSION The first day post-operative pain scores was correlated with age and operating time. Children with a history of chronic tonsillitis were more painful than children without the history.

Objective To evaluate the efficacy of eszopiclone for patients with acute insomnia and the impact of premedication with eszopiclone on sleep structure of patients with acute insomnia.Methods In an open-label,self-control trial was conducted at Changzheng Hospital Sleep Centers,and patients (n =32) with acute insomnia (12 men,20 women; mean age,36.2 years) were administered eszopiclone 3 mg for three consecutive nights.Sleep was monitored via polysomnography.The insomnia severity index (ISI),and mini-mental state examination (MMSE) were used to assess the degree of insomnia and impact of drugs on cognitive function during the day.Results Eszopiclone can shorten sleep latency ( before treatment:(52.92 ± 11.71 ) min,after treatment:(28.2 ± 10.11 ) min; t =-4.376,P ＜0.01 ),prolong total sleep time(before treatment:(365.22 ±30.13) min,after treatment:(429.18 ±26.93 ) min; t =4.102,P ＜ 0.01 ),decrease wake up times( before treatment:( 5.00 ± 1.92 ) times,after treatment:( 2.73 ± 0.91 )times; t =- 4.592,P ＜ 0.01 ),improve sleep efficiency ( before treatment:72.69％ ± 6.32％,after treatment:82.67％ ± 4.16％ ; t =3.371,P ＜ 0.01 ),reduce awake time ( before treatment:( 88.51 ±17.48) min,after treatment:(65.93 ±21.l0)min; t =-4.592,P ＜0.01 ),decrease light sleep ( NREM1 period) the percentage of time ( before treatment:12.54％ ± 2.10％,after treatment:7.30％ ± 2.90％ ;t=-3.155,P ＜ 0.01 ),and increase the percentage of slow wave sleep (before treatment:8.03％ ±5.37％,after treatment:9.31％ ±5.29％; t =4.228,P ＜0.01).No effect was observed on the percentage of NERM2 period (t =0.731,P ＞0.05) and REM period (t =-0.813,P ＞0.05).Eszopiclone can improve the quality of subjective assessment of sleep ( ISI score decreased,t =- 2.551,P ＜ 0.05) and has no significant effect on cognitive function on first the morning after patients taking the medication.Conclusion Eszopiclone can positively regulate the sleep structure in patients with acute insomnia and improve subjective assessment of sleep quality.It is safe and has no significant effect on cognitive function.

Objective To investigate the microRNAs expression profile in human colorectal cancer with or without liver metastasis and try to screen miRNA associated with liver metastasis in colorectal cancer. Methods Twenty five surgical resected colorectal cancer specimens were collected and frozen in liquid nitrogen. Three without liver metastasis and three with liver metastasis were selected, from which total RNAs were isolated. The expressions of miRNAs in these two types of specimens were detected by illumine microRNA microarray, and the difference of miRNA expression was screened. The biochip results were verified with real-time RT-PCR in all colorectal caner specimens. Results The miRNA expression was significantly different in colorectal cancer with liver metastasis and without liver metastasis. Compared with colorectal cancer without liver metastasis, 28 miRNA expressions was different in colorectal cancer with liver metastasis, 4 up regulated and 24 down regulated. The quantity of miR-139-3p expression in colorectal cancer with liver metastasis was 1.75±0.40, up regulated compared with that incolorectal cancer without liver metastasis(0. 69 ±0.58,P＜0.05). The quantity of miR-19a expression in liver metastasis was 0. 39±0. 20, downregulated compare with no liver metastasis( 1.38 ± 0.98, P＜0. 05). The result of miRNA biochip was consistent with that of RT-PCR. Conclusion The difference of miRNA expression might relate to liver metastasis of colorectal cancer. The specific miRNAs expression profile might provide new target for diagnosis and treatment of colorectal cancer with liver metastasis.
