Cerebral salt wasting is characterized by inappropriate natriuresis and volume contraction with associated cerebral pathology. It is distinct from the syndrome of inappropriate antidiuretic hormone secretion, which is characterized by inappropriate retention of free water. We report a patient with a porencephalic cyst who developed cerebral salt wasting. His initial treatment was supplementation of water and salt, which did not improve natriuresis or volume contraction. Fludrocortisone administration effectively managed the cerebral salt wasting.

OBJECTIVETo observe the effect of sodium bicarbonate combined with ulinastatin on cholinesterase activity for patients with acute phoxim pesticide poisoning.

METHODSA total of 67 eligible patients with acute phoxim pesticide poisoning, Who were admitted to the emeryency department of hospital from March 2011 to February 2014, Acording to different treatments au patients were randomly divided into the conventional treatment group (n=34) and the sodium bicarbonate+ulinastatin group (n=35) . The conventional treatment group were given thorough gastric lavage with water, the sodium bicarbonate + ulinastatin group were given gastric lavage with 2% sodium bicarbonate solution. Both groups were given such treatments as catharsis, administration of oxygen, fluid infusion, diuresis, and antidotes such as atropine and pralidoxime methylchloride. On the basis of comprehensive treatment, people in the sodium bicarbonate+ulinastatin group were given 5% sodium bicarbonate injection and ulinastatin. The clinical effect of the two groups were compared.

RESULTSThe serum cholinesterase activity of the sodium bicarbonate+ulinastatin group was significantly higher than the conventional treatment group from the 5th day, and the difference was statistically significant (P<0.05) . The total atropine dosage, total pralidoxime methylchloride dosage and hospitalization days were better than the conventional treatment group, and the differences were statistically significant (P<0.05) . The difference in the time of atropinization between the two groups was not statistically significant (P>0.05) . The results of arterial blood pH, HCO3- of the sodium bicarbonate + ulinastatin group were higher than the conventional treatment group, and the difference of HCO3- at the 10th day was statistically significant (P<0.05) .

CONCLUSIONSSodium bicarbonate combined with ulinastatin can improve the therapeutic effect and reduce complications in the treatment of acute phoxim pesticide poisoning, and have beneficial effects on the recovery of cholinesterase activity.

Objective: To determine the electrophysiological effects and related mechanisms of late sodium current inhibitors on hearts with short QT intervals. Methods: The electrophysiological study was performed on isolated Langendorff perfused rabbit hearts. A total of 80 New Zealand White rabbits were used and 34 hearts without drug treatment were defined as control group A, these hearts were then treated with I_KATP opener pinacidil, defined as pinacidil group A. Then, 27 hearts from pinacidil group A were selected to receive combined perfusion with sodium channel inhibitors or quinidine, a traditional drug used to treat short QT syndrome, including ranolazine combined group (n=9), mexiletine combined group (n=9), and quinidine combined group (n=9). Nineteen out of the remaining 46 New Zealand rabbits were selected as control group B (no drug treatments, n=19), and then treated with pinacidil, defined as pinacidil group B (n=19). The remaining 27 rabbits were treated with sodium inhibitors or quinidine alone, including ranolazine alone group (n=9), mexiletine alone group (n=9), and quinidine alone group (n=9). Electrocardiogram (ECG) physiological parameters of control group A and pinacidil group A were collected. In control group B and pinacidil group B, programmed electrical stimulation was used to induce ventricular arrhythmias and ECG was collected. ECG physiological parameters and ventricular arrhythmia status of various groups were analyzed. The concentrations of pinacidil, ranolazine, mexiletine and quinidine used in this study were 30, 10, 30 and 1 μmol/L, respectively. Results: Compared with control group A, the QT interval, 90% of the repolarization in epicardial and endocardial monophasic action potential duration (MAPD₉₀-Epi, MAPD₉₀-Endo) was shortened, the transmural dispersion of repolarization (TDR) was increased, and the effective refractor period (ERP) and post-repolarization refractoriness (PRR) were reduced in pinacidil group A (all P<0.05). Compared with the pinacidil group A, MAPD₉₀-Epi, MAPD₉₀-Endo, QT interval changes were reversed in quinidine combined group and mexiletine combined group (all P<0.05), but not in ranolazine combined group. All these three drugs reversed the pinacidil-induced increases of TDR and the decreases of ERP and PRR. The induced ventricular arrhythmia rate was 0 in control group B, and increased to 10/19 (χ²=13.6, P<0.05) in pinacidil group B during programmed electrical stimulation. Compared with the pinacidil group B, incidences of ventricular arrhythmia decreased to 11% (1/9), 11% (1/9) and 0 (0/9) (χ²=4.5, 4.5, 7.4, P<0.05) respectively in ranolazine group, mexiletine group and quinidine group. Conclusions: Inhibition of late sodium current does not increase but even decreases the risk of malignant arrhythmia in hearts with a shortened QT interval. The antiarrhythmic mechanism might be associated with the reversal of the increase of TDR and the decrease of refractoriness (including both ERP and PRR) of hearts with shortened QT interval.

OBJECTIVE: The study was aimed to investigate the effects of different levels of pressure and duration of carbon dioxide and saline in the neck of rabbits on metabolic, hemodynamic, serum sodium concentrations and hematocrit changes. METHOD: Twenty-one New Zealand rabbits were randomly divided into 7 groups according to the following pressure of CO2 or saline: 0 kPa, 0.67 kPa CO2, 1.33 kPa CO2, 2.00 kPa CO2, 0.67 kPa saline, 1.33 kPa saline, and 2.00 kPa saline. In order to make a space for the endoscopic thyroidectomy, we filled the neck of rabbits with carbon dioxide and saline. Arterial partial pressure of CO2 (PaCO2), pH, heart rate (HR), mean arterial pressure (MAP), central venous pressure (CVP), serum sodium concentration and hematocrit were measured at baseline, 45 min and 90 min after filling with gas or saline and 30 min post-filling. RESULT: Insufflation of CO2 at 0.67 kPa did not have any significant effect on the parameters, PaCO2 increased significantly 45 min and 90 min after insufflation of 1.33 kPa CO2 (P < 0.01). Marked changes in PaCO2, pH and CVP occurred 45 min and 90 min after insufflation of 2.00 kPa CO2 (P < 0.01), and the parameters did not return to baseline in 30 min after desufflation (P < 0.05). In animals receiving saline irrigation no significant changes occurred in PaCO2, pH and serum sodium concentrations at any time point. There was a tendency of decrease in HCT, but no statistically significant changes were found (P > 0.05). CVP increased significantly 90 min after saline irrigation at 1.33 kPa (P < 0.05). A significant increase in CVP occurred 45 min and 90 min after saline irrigation at 2.00 kPa (P < 0.05). No significant changes in HR and MAP occurred in all animals. CONCLUSION Filling with saline which does not cause hypercapnia, acidosis or dilutional hyponatremia can be used in endoscopic neck surgery to create and maintain a working space.

OBJECTIVETo evaluate the impact of universal salt iodization using monitoring data on correctional status of iodine deficiency and hospitalized thyroid diseases.

METHODSRetrospective survey was conducted to collect medical records of hospitalized thyroid disease cases. Routine monitoring data on population iodine nutrition status and goiter prevalence were analyzed.

RESULTSThe coverage of adequately iodized salt was consistently above 95%. Hospitalization rate of thyroid diseases rose steadily, and peaked at 54.5 per 100,000. The proportion of hospitalized thyroid disease among hospitalized diseases also rose with female and those aged above 40 years old mostly affected. The proportion of hospitalized hyperthyroidism among total hospitalized thyroid disease rose from 13.6% to 34.7%.

CONCLUSIONSUniversal salt iodization might eliminate iodine deficiency while other impact still exists. However, the benefits of universal salt iodization should be far overweight the adverse effects.
