Objective To compare the anesthetic effects of remifentanil and fentanyl in elderly patient undergoing transurethral electro-vaporization of the prostate.Methods Eighty cases of the elderly patients (age ≥60 years) with transurethral resection of the prostate operation in the hospital were randomly divided into remifentanil group(R group,n =40) and fentanyl group (F group,n =40).Patients in R group and F group were administrated remifentanil and fentanyl respectively for induction and maintenance of anesthesia.The following indices were recorded including the changes of emodynamics (lood pressure,heart rate) in before-and after-anesthesia,postoperative recovery (spontaneous breathing recovery time,open the recovery time,extubation time) and the adverse reaction within 24 hours after operation (awareness during operation,nausea,vomiting).Results Blood pressures,heart rate of after-anesthesia in R group were lower than that in before-anesthesia and F group,the difference were significant(Blood pressures:F within group =58.306,P within group =0.000,F interactive group =142.450,p interactive group =0.000,F between group =7.417,P between group =0.010;heart rate:F within group =41.512,P within group =0.000,F interactive group =269.103,P interactive group =0.000,F between grouP =39.703,P between group =0.000).Spontaneous breathing recovery time,opening eye time and extubation time in group R were significantly shorter than that of F group (Spontaneous breathing recovery time:(7.5 ± 1.3) min vs.(10.7 ± 3.1) min,t =3.011 ; Opening eye time:(13.5 ± 3.2) min vs.(18.3 ± 5.2) min,t =2.611 ; Extubation time:(24.4 ± 5.5) min vs.(29.2 ± 7.1) min,t =2.696 ; all P ＜ 0.05).No significant differences were found in R and F group in terms of intraoperative awareness postoperative nausea,vomiting (P ＞ 0.05).Conclusion Remifentanil used in elderly patients with transurethral electro-vaporization of the prostate was safer and more effective than fentanyl.Meanwhile postoperative recovery in Remifentanil patient was more rapidly.Therefore Remifentanil was ideal drug during the process clinical anesthesia.

Objective To study the relationship between hearing loss and serum bilirubin of neonates with hypercholesterolemia .Methods The serum bilirubin level and auditory brainstem response thresholds of 70 hyper_cholesterolemia neonates of full term pregnancy and normal weight were tested ,and the correlations of serum biliru_bin ,and occurrence time of jaundice with hearing threshold were analyzed .ResuIts Among the 70 neonates ,there were 17 cases with normal ABR thresholds and 53 with abnormal ABR thresholds ,including 27 with middle and se_rious hearing loss .In the cases of serum bilirubin less than 342μmol/L ,the percentage of cases with middle and se_rious hearing loss and with occurrence time of jaundice less than 48 hours was higher than theses cases with occur_rence time of jaundice more than 48 hours (P<0 .05) .In the cases of serum bilirubin higher than 342μmol/L ,there was no obvious difference between the percentage of cases of middle and serious hearing loss with occurrence time of jaundice less than 48 hours and those with occurrence time of jaundice more than 48 hours .Among the 53 cases with abnormal hearing thresholds ,positive correlation was observed between serum bilirubin and ABR threshold (r=0 .041) ,whereas negative correlation was observed between occurrence time of jaundice and ABR threshold (r=-0 .291) .ConcIusion The higher probability of hearing loss for hypercholesterolemia neonates with earlier occur_rence of jaundice ,the more serious hearing loss with higher serum bilirubin .

Objective To systematically evaluate the efficacy of acupotomy treatment for the stenosing tenovaginitis of flexor digitorum.Methods Articles about RCTs of acupotomy treatment and local blocking for the treatment of stenosing tenovaginitis of flexor digitorum were retrieved from CBM, CNKI, VIP, Wanfang database, PubMed, Embase, and Cochrane library. And then according to the requirement of Cochrane Handbook for Systemetic Reviews 5.1.0, two reviewers independently chose tests, extracted data, had a cross check, accessed methodological qualities and finally used RevMan 5.3 software for Meta analysis. The total effective rate, cure rate and improvement rate of acupotomy treatment and local blocking in treating stenosing tenovaginitis of flexor digitorum were assessed by using odds ratio (OR).Results Totally 10 articles involving 1426 cases were included. The cure rate in acupotomy treatment group was higher than that of local blocking group [OR=13.11 (95% CI: 8.23–20.89),Z=10.83 (P<0.000 01)], funnel plot Begg’s testP=0.858, Egger’s testP=0.579; the improvement rate of local blocking rate was higher than that of acupotomy treatment group [OR=0.14 (95% CI: 0.10–0.19),Z=11.60 (P<0.000 01)], funnel plot Begg’s test P=1.000, Egger’s testP=0.926; the total effective rate of acupotomy treatment group was higher than that of local blocking group [OR=18.26 (95% CI: 9.95–33.50),Z=9.38 (P<0.000 01)], funnel plot Begg’s testP=0.592, Egger’s testP=0.936.Conclusion Acupotomy treatment for stenosing tenovaginitis of flexor digitorum is superior to local blocking injection. However, the quality of the RCTs is low, so more large-sample, multi-center, and high-quality clinical RCTs are required for further verification.

UNLABELLEDTo study the effect of a Chinese herbal prescription on external calcium deposition to weight-bearing bone in simulated weightlessness rats.

METHODTwenty-one male Wistar rats were divided into 3 groups: control group, tail suspension group, tail suspension with Chinese medicine group which takes a Chinese herbal prescription extract (containing Radix Rehmanniae Preparata, Radix Acanthopanacis Bidentatae, Radix Astragali, Radix Angelicae Sinensis, Concha Ostreae prepared by acetic acid) by intragastric administration. After 1 week adaption, there start off 3 weeks simulated weightlessness by tail suspension. At the eleventh day of simulated weightlessness, every rat was given one equal dose of 41Ca tracer by intragastric administration. Right femurs were separated as experiment over, and the ratio of 41Ca to 40Ca (41Ca/40Ca) was measured by accelerator mass spectrometry (AMS), while total femur calcium was measured by inductively coupled plasma-atomic emission spectroscopy (ICP-AES). Femur 41Ca deposition amount (DA) and femur 41Ca deposition ratio (DR) were calculated.

RESULTThe results showed that compared with control group, 41Ca/40Ca decreased significantly (P < 0.001) in tail suspension group, while in tail suspension with Chinese medicine group, it significantly increased (P < 0.05). DA and DR were both decreased significantly (P < 0.001) in tail suspension group, but no significant change in tail suspension with Chinese medicine group as compared with control group. Compared with tail suspension group, DA and DR increased significantly (P < 0.001) in tail suspension with Chinese medicine group.

CONCLUSIONSimulated weightlessness by tail suspension can cause decreased deposition of external calcium to weight-bearing bone, and the Chinese herbal prescription in this trial is effective to prevent the decrease. Moreover, multiple mechanisms may contribute to weightlessness induced osteoporosis, besides calcium deposition disturbance.

Background:Acute lung injury(ALI)is the most common organ dysfunction in severe acute pancreatitis(SAP).Somatostatin analogue octreotide is a common used drug in acute pancreatitis.Aims:To explore the protective mechanism of octreotide on lung injury in SAP mice.Methods:In the first part,the experimental mice were randomly assigned into four groups.SAP model was induced by caerulin and lipopolysaccharide,and the mice were sacrificed 24 hours,48 hours and 72 hours after establishment.HE staining was used to observe the pathological score of pancreas and lung.Serum amylase and lung tissue myeloperoxidase(MPO)activity were detected.Real-time quantitative PCR was used to detect mRNA expressions of pyroptosis-related molecules apoptosis-associated speck-like protein containing a CARD(ASC),caspase-1,Gasdermin D(GSDMD),interleukin(IL)-1β,IL-18 and inflammatory factors IL-6,tumor necrosis factor(TNF)-α,high mobility group protein B1(HMGB1)in lung tissue.Western blotting was used to detect protein expressions of NOD-like receptor thermal protein domain associated protein 3(NLRP3),caspase-1,GSDMD and IL-1β in lung tissue.In the second part,mice were randomly divided into control group,SAP group,and octreotide group.HE staining was used to observe the pathological score of pancreas and lung.Serum amylase and lung tissue MPO activity were detected.Real-time quantitative PCR was used to detect mRNA expressions of pyroptosis-related molecules caspase-1,ASC,IL-1β,IL-18 and inflammatory factors IL-6,TNF-α,HMGB1.Immunofluorescence was used to detect protein expressions of NLRP3,caspase-1,GSDMD,ASC,IL-1β in lung tissue.Results:In the first part,compared with control group,pathological score of pancreas and lung tissue,serum amylase and MPO activity were significantly increased in SAP group(all P<0.05),mRNA expressions of pyroptosis-related molecules caspase-1,ASC,GSDMD,IL-1β,IL-18 and inflammatory factors IL-6,TNF-α,HMGB1 were significantly increased(all P<0.05),protein expressions of NLRP3,caspase-1,GSDMD and IL-1β in lung tissue were significantly increased(all P<0.05),especially in 24 hours after establishment group.In the second part,compared with SAP group,pathological score of pancreas and lung tissue,serum amylase were significantly decreased in octreotide group(all P<0.05),mRNA expressions of pyroptosis-related molecules caspase-1,ASC,IL-1β,IL-18 and inflammatory factors IL-6,TNF-α,HMGB1 were significantly decreased in lung tissue in octreotide group(all P<0.05),protein expressions of NLRP3,caspase-1,GSDMD,ASC and IL-1β in lung tissue were significantly decreased(all P<0.05).Conclusions:Cell pyroptosis is involved in the occurrence and development of lung injury in SAP mice,and octreotide may attenuate lung injury in SAP mice by inhibiting pyroptosis.

Objective: To investigate the clinical characteristics, prognosis and affected branches of vestibular neuritis in children. Methods: Twenty-five patients with vestibular neuritis in ENT department, Beijing Children′s Hospital, from October 2015 to October 2016, were collected. All patients were 4-14 (mean 9.8) years old including 17 boys and 8 girls. The clinical manifestations history, pure tone audiometry (PTA), vestibular function tests were done for each patient. We also took the blood samples for pathogenic virus in order to analyze the premorbid risk factors. Results: Rotational vertigo were complained by all presents. There were 17 cases (68%, 17/25) with nausea and vomiting and 19 cases (76%, 19/25) with balance dysfunction. There were 12 cases (60%, 12/20) with positive results in 20 blood samples for virology, among which 6 cases of influenza B virus and 4 cases of herpes simplex virus, 1 case of cytomegalovirus and 1 case of coxsackie were identified. The results of PTA were normal. Bithermal caloric test was abnormal in 22 cases (88%, 22/25). The ocular vestibular-evoked myogenic potential (oVEMP) in 12 cases (48%, 12/25) and cervical vestibular-evoked myogenic potential (cVEMP) in 5 cases (20%, 5/25) were abnormal. The bithermal caloric test along with oVEMP and cVEMP in 4 cases (16%, 4/25) were abnormal. The bithermal caloric test and oVEMP in 7 cases (28%, 7/25) were abnormal. The bithermal caloric test in 11 cases (44%, 11/25) were abnormal. The oVEMP in 1 cases (4%, 1/25) was abnormal. The cVEMP in 1 cases (4%, 1/25) was abnormal. All patients recovered well, but the time varied. The symptoms of 21 patients were complete recovery within 1 month. 3 patients were complete recovery within 2 months (aged 8 - 14 years old). One patient was complete recovery within 6 months (aged 13 years old). Conclusion Rotary vertigo is most commonly in children with vestibular neuritis, accompany with imbalance and vomiting. The vestibular neuritis in children might be related with upper respiratory tract infection. Audiometry test is normal. Because of the bithermal caloric test and oVEMP are obvious abnormality, therefore it is speculated that the superior vestibular nerve may most commonly be affected. The younger patients with vestibular neuritis recovered more quickly than the older children.
