Objective To study the clinical efficacy of naloxone combined with edaravone on acute alcoholism. Methods One hundred and twenty-five patients with acute alcoholism were randomly divided into the control and treatment groups. The control group accepted conventional treatment and taking naloxone, while the treatment group accepted edaravone on the basis. Before and after treatment,the treatment recovery time,recovery respiratory rate time and symptom disappearance time were recorded. The malondialdehyde (MDA), superoxide dismutase (SOD), glutathione (GSH), neuron-specific enolase (NSE), S-100βand vascular cell adhesion points-1 (VCAM-1) were detected. Results After treatment,the recovery time and recovery respiratory rate time of the treatment group were significantly shorter than those of the control group ( <0.05) . In the control group, S-100β was significantly improved after treatment ( <0.05) . NSE, S-100β, VCAM-1 and MDA have significantly decreased ( <0.05) after treatment in the treatment group. Compared with the control group, there were significant differences of S-100β,VCAM-1 and MDA in the treatment group before and after treatment (<0.05) . While SOD and GSH have significantly increased ( <0.05) after treatment and showed significant differences compared with the control group ( <0.05) . Conclusion Naloxone and edaravone combination therapy can improve oxidative stress and nerve damage, which help early rehabilitation in patients with acute alcoholism.

To observe the time-dependent course of potentiation of vecuronium produced by 1MAC of end-tidal sevoflurane and isoflurane. Method: At the beginning, a steady infusion rate of vecuronium to maintain 90 of neuromuscular block was established in 40 patient undergoing neurosurgical procedures under propofol fentanyl nitrous oxide oxygen anesthesia. The patients were randomly assigned to receiving IMAC end-tidal concentration of either sevoflurane (Group Sev) or isoflurane(Group Iso). Vecuronium infusion rate was adjusted to maintain 90%, neuromuscular block. The change of infusion rate of vecuronium with time was observed after inhalation of Sev or Iso. Result: Sev and Iso decreased the infusion dosage of vecuronium in an exponential manner, maximal potentiation occurred 90 min after inhalation. Maximal reduction in infusion rate was 67.87% in group Sev and 69.87% in group Iso without the significant difference between them. Conclusion: Sev and Iso can potentate the muscular relaxation of vecuronium at similar degree in strong time-dependent way.

Objective To assess the effects of hyperventilation on the balance of cerebral oxygen supply and consumption during craniotomy Methods Twenty ASA Ⅰ Ⅱ patients with supratentorial tumor undergoing elective craniotomy were studied Anesthesia was induced with fentanyl 2 4 ?g/kg and propofol 1 2mg/kg I V and tracheal intubation was facilitated with succinylcholine 1 5 2 0mg/kg I V After tracheal intubation the patients were mechanically ventilated Anesthesia was maintained with isoflurane with or without nitrous oxide and intermittent intravenous bolus of vecuroinum The patients were randomly divided into two groups : in group Ⅰ anesthesia was maintained with 1 5% isoflurane alone (ISO group, n=10); in group Ⅱ with 0 8% isoflurane and 60% 65% N 2O(ISO N 2O group, n=10) Demographic data including age, sex and weight were not significantly different between the two groups In group Ⅰ there were 6 male and 4 female, the mean age was (40 1?9 7) years and weight (64 5?7 3)kg whereas in group Ⅱ there were 5 male and 5 female, mean age was(43 6?8 4)years and mean body weight (62 7?6 5)kg After the opening of dura mechanical ventilation was regulated to maintain PaCO 2 at 4 7 6 0kPa(normal ventilation), 0 9) Arterial and venous blood lactate was within normal range but had a tendency to increase Conclusions Severe hyperventilation influences the balance of cerebral oxygen supply and consumption significantly during either isoflurane or isoflurane N 2O anesthesia at equal MAC, particularly in ISO N 2O group Severe hyperventilation should not be used during anesthesia for brain surgery

Objective To analyze the clinical and immunological features of 45 pediatric patients with lupus nephritis (LN). Methods Forty-five LN patients were included in this study. Clinical, pathological data and immunological parameters were retrospectively analyzed. Results Forty-five LN patients had 6 males and 39 females, with the mean onset age of (10.9 ± 2.8) years. Acute nephritis was the most common type, accounting for 42.2%. Nephrotic syndrome accounted for 31.1%. Renal biopsy showed class II (17.8%), III (4.4%), IV (48.9%), V (2.2%), V+III (6.7%)and V+IV (13.3%)in 42 cases. The remis-sion rate reached 91.1%in the early therapeutic stage, and 15.0%patients recurred after 24-month follow-up. Conclusions The clinical manifestations of LN children are diverse. The renal pathology is complex. The clinical manifestations in part of the chil-dren are not consistent with renal pathology.

Objective: Our purpose was to study the effect of anisodamine on the injury of myocardium after myocardial ischemia reperfusion. Methods: Eighteen patients (ASA grade Ⅱto Ⅲ) scheduled for valve replacement, were randomly divided into 2 groups during extracorporeal circulation. Anisodamine (0.25 mg/kg) was given intravenously in the anisodamine group before reperfusion. Equivalent volumes of normal saline were administered in the control group. The central venous blood samples were collected at different time after ischemia and reperfusion. We then measured the concentrations of lactic dehydrogenase (LDH), creatine kinase (CK), and malondiadehyde (MDA) with biochemical methods. Results: The levels of serum LDH, CK, and plasma MDA increased significantly in the control group during ischemia and reperfusion. In the anisodamine group, the levels of serum LDH and CK increased. But the values were lower at corresponding time than those in the control group (P<0.05) during reperfusion. The plasma level of MDA unchanged in the anisodamine group during ischemia and reperfusion. The postoperative cardiac function recovered much more better in the anisodamine group. Conclusion: Anisodamine can reduce the degree of reperfusion injury. A certain protective effect on myocardial ischemia reperfusion injury exsists during valve replacement.

Objective: This paper constructed the children’s multiple sports activity module from the perspective of Multiple Intelligences, and explored the effect of sports activity module on physical fitness of young children. Methods: A total of 176 children aged 3-6 years were randomly divided into control and experimental classes for 24 weeks, 5 times/week, 30 minutes/time. Children in the experimental class received multi-sports activity module, and children in the control class received general sports activities. Activity duration, intensity and frequency of the experimental class and the control class were basically the same. Results: This study constructed the children’s multiple sports activity module with eight pieces of content from the perspective of Multiple Intelligences. Before the intervention, there was no statistical difference between the experimental class and the control class(P>0.05), and the height of the children aged 3 to 4 years after the intervention in the experimental class [(109.29±6.56)cm] was significantly higher than that before the intervention[(105.11±5.51)cm](P<0.01). After intervention, the walking balance beam, the 10-meter reverse run and the feet continuous jump of the children aged 3 to 4 years in the experimental class were significantly higher than those in the control class(P<0.01). The standing long jump, sitting position forward flexion of the children aged 3 to 4 years were also significantly higher than those in the control class(P<0.05). The balance beam of the children aged 4 to 5 years in the experimental class was significantly higher than that in the control class(P<0.01). Tennis throw, sitting position forward flexion, 10-meter reverse run, feet continuous jump of the children aged 4 to 5 years were also significantly higher than the control class(P<0.05). The walking balance beam of the children aged 5 to 6 years was significantly higher in the experimental class than that in the control class(P<0.01), the standing long jump tennis throw, the sitting position forward flexion, The 10-meter reverse run and the continuous jump of the feet of the children aged 5 to 6 years were also significantly higher than those in the control group(P<0.05). Conclusion The multi-sports activity module is superior to the general sports activities in developing children’s physical fitness and can be promoted as a project to develop children’s physical fitness.

OBJECTIVETo analyze deaf-related genes in patients with nonsyndromic hearing loss (NSHL) and set up a prenatal diagnosis system for such patients.

METHODSNine NSHL families were collected. Potential mutations of GJB2 (35delG, 176del16, 235delC, 299delAT), SLC26A4 (2168A> G, IVS7-2A> G), GJB3 (538C> T) and mtDNA (1494C> T, 12S rRNA 1555A> G) were detected by direct sequencing. Maternal blood contamination was excluded prior to the testing.

RESULTSSixteen patients from 4 families were detected with GJB2 mutations, 8 patients from 2 families were found with SLC26A4 mutations, and 4 patients from 2 families were found with mutations in mtDNA. For 2 patients from one remaining family, no mutations were found with above genes.

CONCLUSIONA diagnostic system for NSHL has been established, which may provide a basis for prenatal diagnosis and genetic counseling to NSHL families.

OBJECTIVETo investigate the role of endogenous carbon monoxide (CO) in hypoxia.

METHODSAfter rats were inhaled with hypoxic gases and the heme oxygenase inhibitor ZnPPIX was administered, we measured the CO levels in plasma, liver, lung and kidney. Meanwhile plasma cGMP levels were observed. Furthermore, we recorded the change of hemodynamic and blood gases.

RESULTSAcute mild hypoxia (10% O2) significantly increaed CO levels in plasma as well as liver, kidney and lung, while acute severe hypoxia (5% O2) significantly decreased CO levels in plasma as well as liver, kidney and lung. In addition, the former significantly elevated cGMP levels in plasma while the latter markedly reduced cGMP levels in plasma. The hemodynamic change occurred in accordance with the changes carbon monoxide.

CONCLUSIONOur results indicate, for the first time, that the endogenous carbon monoxide plays an important role in regulating the vessel tone during hypoxia.

This study was aimed to identify the photodegradation impurities (PD1 and PD2) in melphalan hydrochloride and establish a method for determining PD1 and PD2.The structures of the photodegradation impurities were inferred by LC-MS/MS.The impurities were confirmed by comparing with synthesized impurities.An HILIC method was established to determine PD1 and PD2.The method was carried out on an Atlantis HILIC column(4.6 mm × 150 mm,3 μm) with the mobile phase consisting of 0.1 mol/L ammonium formate (adjusted to pH 3.0 with formic acid) and acetonitrile (13∶ 87) at the flow rate of 1.0 mL/min.The column temperature was 35 ℃.The detection wavelength was 260 nm.PD1 and PD2 were characterized as 4-amino-L-phenylalanine hydrochloride and 4-(2-chloroethyl) amino-L-phenylalanine hydrochloride,respectively.Melphalan hydrochloride,PD1 and PD2 were separated completely under the HILIC condition.The established HILIC method can be used to determine the photodegradation impurities.

Objective To investigate the MR findings of fetal cleft lip (CL) and evaluate the advantages and limitations of MRI in the diagnosis. Methods Twelve pregnant women suspicious of fetal CL/cleft palate(CP) on ultrasonography were enrolled in the study. The findings of ultrasonography, MRI and following-up were compared. Results MRI and ultrasonography detected 12 fetuses with CL/CP. The following-up results showed 1 case with incomplete cleft lip and the other 11 cases with complete cleft lips and cleft palates. MRI and unltrasonography were consistent with the follow-up in CL detection, showing completed or uncompleted soft tissue interruption of the fetal lips with amniotic fluid filling which is high signal on T_2WI. On MRI, CP showed discontinuous of the soft tissue which were interrupted by long T_2 signal and communicating with oral cavity and nasal cavity. MRI missed 1 case and excluded 1 case of CP. Ultrasonography predicted 5 case of CL, excluded 1 CP but missed 6 cases. The accuracy, sensitivity and specificity in detection CL/CP was 91.7% (11/12), 90.9% (10/11), 100% (1/1) for MRI and 50.0% (6/12),45.5% (5/11), 100% (1/1) for ultrasonography, respectively. Conclusion MR imaging had advantage over ultrasonography in detecting CP, MRI is an essential when CP is suspicious on ultrasonography.
