Objective To observe clinical application of the apparent Shikani laryngoscope in difficult airway, so as to provide reference for basic-level hospitals to deal with difficult airway. Methods 50 patients with difficult airway were randomly divided into 2 groups:Shikani laryngoscope group (S) that direct laryngoscope group (M) . After conventional induction, patients in two groups were given endotracheal intubation with different intubation tools by the same anesthesiologist, then the intubation time and the one-time success rate of intubation were compared between two groups. The hemodynamics of patients, were observed in two groups,the HR,SBP,DBP and SPO2 at before (T0),during (T1),2 min after (T2) and 5 min after intubation (T3) were recorded. The complications including gingival and oral mucosa bleeding, sore throat, hoarseness were also recorded in two groups.Results During the process of intubation, the hemodynamic changes of patients had statistically significant difference between T0 and T1, T2,T3 subgroups ( <0.05),T2 and T3 subgroups ( <0.05) . The intubation had less influence on hemodynamics of patients in group S than M group,but the SPO2 and T0 had no significant difference between two groups ( >0.05) .Comared with M group,the one-time success rate of intubation was higher,and the intubation time was shorter in S group and there were significant differences ( <0.05) . There was no significant difference in the intubation complications between the two groups ( > 0.05), and this may be associated with small sample cases. Conclusion Compared with ordinary laryngoscope, Shikani laryngoscope has incomparable advantages in handling difficult airway and is convenient to apply,so it is worth popularizing in basic-level hospitals.

Objective:To summarize the clinical features, genetic testing and treatment efficacy of 6 children with Dent disease.Methods:Six children diagnosed with Dent disease in Guangzhou Women and Children′s Medical Center from January 2014 to March 2019 were enrolled.Their medical history, clinical manifestations, laboratory results, genetic test results, and proteinuria level, calciuria level and renal function after medication were measured.Results:All patients were male, with the onset age ranged from 1 to 9 years old.They were followed up for 6 months to 4 years.All the children had low molecular weight proteinuria.Urine protein electrophoresis showed that the ratio of low molecular weight proteinuria in only 2 cases was more than 50%.Renal biopsy suggested that all cases were combined with glomerular lesions.Five cases had hypercalciuria.Under the microscope, there were 5 cases of hematuria.Two case had rickets, and there was no renal calcium deposition and hypophosphatemia.Five cases were detected with CLCN5 mutations, of which p. C160Yfs*49 and p. G523D were first reported.One case had an OCRL1 mutation.Patients were treated with Hydrochlorothiazide and angiotensin converting enzyme inhibitor (ACEI). The 24 h urinary calcium level after treatment was lower than that before treatment [0.40 (0.24, 0.43) mmol/kg vs.0.12 (0.11, 0.14) mmol/kg, U=2.00, P<0.01]. However, there was no significant decrease in the 24 h-urinary protein level before and after treatment [77.09 (62.41, 88.01) mg/kg vs.80.33 (66.03, 92.52) mg/kg, U=12.00, P>0.05]. Conclusions:Dent disease is mainly characterized by low molecular weight proteinuria, and some patients may not be associated with hypercalciuria.Gene tests help to identify the disease type.ACEI and Hydrochlorothiazide can reduce the urinary calcium level, but cannot improve the level of urinary protein.

OBJECTIVETo study the effect of phenformin hydrochloride that may be illegally added in traditional Chinese medicine preparations on the pharmacokinetics of puerarin in rats.
METHODRats were randomly divided into the single pueraria group and the phenformin hydrochloride combined with pueraria group. After oral administration in the two groups, their bloods were sampled at different time points to determine the drug concentration of puerarin in rat blood and calculate pharmacokinetic parameters.
RESULTAfter oral administration with pueraria extracts and phenformin hydrochloride combined with pueraria extracts, the two groups showed main pharmacokinetic parameters as follows: Cmax were (2.39 +/- 1.01), (1.03 +/- 0.35) mg x L(-1), respectively; Tmax were (0.50 +/- 0.09), (1.5 +/- 0.5) h, respectively; Ke were (0.153 +/- 0.028), (0.172 +/- 0.042) h(-1), respectively; t(1/2) were (4.65 +/- 0.86), (4.20 +/- 0.81) h, respectively; AUC(0-t), were (5.73 +/- 2.60), (5.45 +/- 1.81) mg x h x L(-1), respectively; AUC(0-infinity) were (6.72 +/- 2.89), (6.26 +/- 1.88) mg x h x L(-1), respectively. Compared with the single puerarin group, the Cmax was significantly decreased (P < 0.05) and the Tmax was markedly longer (P < 0.01) than the hydrochloride combined with pueraria group.
CONCLUSIONPhenformin hydrochloride can slow down the absorption process of puerarin and change the pharmacokinetic process of puerarin to some extent.

OBJECTIVETo study the changes of the amplitude-integrated electroencephalography (aEEG) tracings within 6 hours after birth in term infants with hypoxic-ischemic encephalopathy (HIE) and explore the value of aEEG in early diagnosis and prediction of neurological outcome in term infants.
METHODSFrom May 2003 to February 2005, 33 term infants with HIE at the Division of Neonatology, Pediatric Hospital of Fudan University were studied by aEEG within 6 hours after birth. The results of aEEG were categorized into three groups (normal, mildly abnormal and severely abnormal aEEG), while HIE was clinically classified into three grades (mild, moderate and severe) and the neurological outcomes at 18 months were assessed (normal, disabled and dead). The correlation between the results of aEEG, severity of HIE and neurological outcome at 18 months were analyzed, respectively. The values of aEEG on early diagnosis and neurological outcome prediction of HIE were analyzed.
RESULTSAmong the 33 term infants with HIE, 20 infants had normal aEEG (normal amplitude aEEG), 5 had mildly abnormal aEEG (4 with mildly abnormal amplitude aEEG, 1 with normal amplitude and seizure) and 8 had severely abnormal aEEG (2 with mildly abnormal aEEG and seizures, 4 with severely abnormal amplitude and 2 with severely abnormal amplitude and seizures), respectively. Seventeen infants (51.5%) had mild HIE, 19 moderate (27.3%) and 7 (21.2%) severe HIE, respectively. Twenty-five cases were followed up, which showed that 19 had normal neurological outcome, 1 had disability and 5 died. By CMH square analysis and Spearman rank correlation analysis, the results of aEEG classification were correlated with the severity of HIE and the neurological outcome of term infants. Abnormal aEEG could predict the severity of HIE in term infants with a sensitivity of 100%, specificity of 81.3%, positive predictive value of 85.0% and negative predictive value of 100%, respectively. Abnormal aEEG could predict the neurological outcome of term infants with HIE, which showed a sensitivity of 100%, specificity of 90.9%, positive predictive value of 93.3% and negative predictive value of 100%, respectively. Severely abnormal aEEG could predict the severe HIE in term infants with sensitivity of 96.2%, specificity of 100%, positive predictive value of 100% and negative predictive value of 87.5%, respectively. Severely abnormal aEEG could predict the neurological outcome of term infants with HIE, which showed sensitivity of 94.7%, specificity of 100%, positive predictive value of 100% and negative predictive value of 85.7%, respectively.
CONCLUSIONSMonitoring with aEEG in term infants with HIE within 6 hours after birth could predict the severity of HIE and its neurological outcome at 18 months.

BACKGROUND: Mainly pathological changes of Parkinson disease (PD)are related to irreversible degeneration and reduction of dopamine neurons of substantia nigra in midbrain; however, oxidative stress reaction plays an important role in onset of PD. 3-nitropropionie acid (3-NP) is an inhibitor of mitochondria compound I, and it can inhibit oxidative phosphorylation so as to restrain energy metabolism. However, professor Riepe from Germany found that small dose of 3-NP can increase the tolerance of neurons to ischemic hypoxia. It is unclear whether it can also strengthen the tolerance of dopamine neurons to neurotoxin.OBJECTIVE: To investigate the possible mechanism and prevention of repetitively preconditioning 3-NP for treating PD.DESIGN: Controlled observational animal study. SETTING: Department of Neurology, Union Hospital affiliated to TongjiMedical College, Huazhong University of Science and Technology. MATERIALS: The experiment was carried out at the Neurological Lab oratory, Union Hospital affiliated to Tongji Medical College, Huazhong U niversity of Science and Technology from March to July 2004. A total of48 C57BL mice, weighing 18-20 g, aged 2-3 months, of both genders, were randomly divided into 6 groups with 8 in each group. ① Blank con trol group: Mice were not medicated. ② 3-NP single administrationgroup: Mice were intraperitoneally injected with 3-NP once. ③ 3-NPrepetitively administrations group: Mice were intraperitoneally injectedwith 3-NP every 5 days for 5 times in total. ④ Neurotoxin group: Micewere intraperitoneally injected with neurotoxin once every day for 5 timesin total. ⑤ 3-NP single preconditioning group: Mice were intraperitoneal ly injected with 3-NP once, and 3 days later, they were intraperitoneallyinjected with neurotoxin once every day for 5 times in total. ⑥ 3-NPrepetitively preconditionings group: Mice were intraperitoneally injectedwith 3-NP and repetitively every 5 days for 5 times in total; 3 days later, mice were intraperitoneally injected with neurotoxin once every day for5 times in total. Dosages of 3-NP and neurotoxin were 20 mg/kg and30 mg/kg, respectively. METHODS: Motor coordination of mice was scored with pole test andtraction test before experiment and at 3 days after the last injection ofneurotoxin. Three days after complete injection, mice were sacrificed rapid ly to measure the contents of malondialdehyde (MDA) and reduced glu tathione (GSH) in the substantia nigra of midbrain. MAIN OUTCOME MEASURES: ① Motor and behavior scores; ② con tent of MDA; ③ content of GSH.~ULTS: All 48 mice were involved in the final analysis. ① Scores of pole test and traction test were decreased in neurotoxin group as compared with those in control group (P<0.01); but the scores were increased after 3-NP single/repetitively preconditionings, and there were significant difference (P<0.05, P<0.01). Meanwhile, there was also significant differencebetween 3-NP repetitively preconditionings group and 3-NP single preconditioning group (P<0.05). ② Content of MDA was increased in neurotoxin group as compared with that in control group, and there was significant difference (P<0.01); content of MDA was decreased after 3-NP single preconditioning as compared with that in neurotoxin group, and there was significant difference (P<0.05); content of MDA was remarkably decreased after 3-NP repetitively preconditionings as compared with that in neurotoxin group, and there was greatly significant difference (P<0.01); meanwhile, there was also significant difference between 3-NP repetitively preconditionings group and 3-NP single preconditioning group (P<0.05). ③As compared with that in blank control group, content GSH in 3-NP single administration group was not changed; content of GSH in 3-NP repetitively administrations group was increased (P<0.05); content of GSH in neurotoxin group was decreased as compared with that in blank control group (P<0.01); content of GSH in 3-NP single preconditioning group was not changed as compared with that in neurotoxin group (P>0.05); content of GSH was increased after 3-NP repetitively preconditionings, and there was significant difference (P<0.05); meanwhile, there was significant difference between 3-NP repetitively preconditionings group and 3-NP single preconditioning group (P<0.05).CONCLUSION: 3-NP repetitively preconditionings can activate synthesis of GSH, protect dopamine neurons through decreasing production of MDA.
