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 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.

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.

BACKGROUNDMolecular hydrogen, as a novel antioxidant, has been proven effective in treating many diseases. This study aimed to evaluate the therapeutic effects of hydrogen saturated saline in treatment of a rat model of diabetes mellitus and a rat model of insulin resistant.

METHODSA rat diabetes mellitus model was established by feeding a high fat/high carbohydrate diet followed by injection of a small dose of streptozotocin, and an insulin resistant model was induced with a high glucose and high fat diet. Hydrogen saturated saline was administered to rats with both models conditions on a daily basis for eight weeks. A pioglitazone-treated group and normal saline-treated group served as positive and negative controls. The general condition, body weight, blood glucose, blood lipids, and serum insulin levels of rats were examined at the 8th week after treatment. The oxidative stress indices, including serum superoxide dismutase (SOD), glutathione (GSH) and malondialdehyde (MDA) were also evaluated after eight weeks of treatment using the commercial kits.

RESULTSHydrogen saturated saline showed great efficiency in improving the insulin sensitivity and lowering blood glucose and lipids. Meanwhile, the therapeutic effects of hydrogen saturated saline were superior to those of pioglitazone. Hydrogen saturated saline markedly attenuated the MDA level and elevated the levels of antioxidants SOD and GSH.

CONCLUSIONHydrogen saturated saline may improve the insulin resistance and alleviate the symptoms of diabetes mellitus by reducing the oxidative stress and enhancing the anti-oxidant system.

OBJECTIVE: To investigate the clinical effect of Shenfu injection combined with glucocorticoid in the treatment of acute left heart failure complicated with bronchospasm. METHODS: A prospective study was conducted.Ninety patients with acute left heart failure complicated with bronchospasm admitted to Huai'an Second People's Hospital from January 2021 to July 2022 were selected and divided into conventional treatment group, hormone therapy group and combined treatment group according to random number table method, with 30 cases in each group. All patients in the 3 groups received basic Western medicine treatment. On this basis, the conventional treatment group was given 0.25-0.50 g aminophylline injection plus 5% glucose injection or 0.9% sodium chloride injection (diabetes patients) 100 mL slow intravenous infusion, 1-2 times a day. In the hormone treatment group, 1 mg of budesonide suspension for inhalation was diluted to 2 mL by 0.9% sodium chloride injection, twice a day, and applied until 48 hours after the pulmonary wheezing disappeared. The combined treatment group was given glucocorticoid combined with Shenfu injection 80 mL plus 5% glucose injection or 0.9% sodium chloride injection (diabetes patients) 250 mL intravenously, once a day. All treated for 1 week. The general data, traditional Chinese medicine (TCM) syndrome score, TCM syndrone efficacy index, acute left heart failure efficacy, bronchospasm efficacy, systolic blood pressure (SBP), mean arterial pressure (MAP), serum N-terminal pro-brain natriuretic peptide (NT-proBNP) level and safety of the 3 groups were compared. The patients were followed up for 6 months, and the mortality and re-hospitalization rate of the 3 groups were recorded. RESULTS: Among the 90 patients, a total of 83 patients completed the study, excluding the cases dropped due to death and other reasons. There were 29 cases in the combined treatment group, 25 cases in the hormone therapy group and 29 cases in the conventional treatment group. There were no significant differences in age, gender, course of disease, and previous history (history of diabetes, history of hypertension, history of hyperlipidemia) among the 3 groups. Therefore, they were comparable. The difference of TCM syndrome score before and after treatment, TCM syndrome efficacy index of combined treatment group and hormone therapy group were higher than those of conventional treatment group [difference of TCM syndrome score: 15.14±5.74, 13.24±5.75 vs. 10.62±5.87, TCM syndrome efficacy index: (67.84±14.31)%, (59.94±14.26)% vs. (48.92±16.74)%, all P < 0.05], and the difference of TCM syndrome score and TCM syndrome efficacy index of combined treatment group were higher than those of hormone treatment group (both P < 0.05). The total effective rate of acute left heart failure and bronchospasm in the combined treatment group was significantly higher than that in the conventional treatment group (total effective rate of acute left heart failure: 96.55% vs. 75.86%, total effective rate of bronchospasm: 93.10% vs. 65.52%, both P < 0.05). The difference of serum NT-proBNP before and after treatment in combination therapy group and hormone therapy group was significantly higher than that in conventional treatment group (ng/L: 7 922.86±5 220.31, 7 314.92±4 450.28 vs. 4 644.79±3 388.23, all P < 0.05), and the difference of serum NT-proBNP before and after treatment in the combined treatment group was significantly higher than that in the hormone treatment group (P < 0.05). There were no significant differences in SBP difference, MAP difference, mortality and re-hospitalization rate among the 3 groups. No adverse reactions occurred in the 3 groups during treatment. CONCLUSIONS Shenfu injection combined with glucocorticoid is effective in the treatment of patients with acute left heart failure complicated with bronchospasm. It is superior to glucocorticoid and aminophylline in relieving bronchospasm, reducing NT-proBNP level and improving total effective rate, and has good prognosis and safety.

OBJECTIVETo observe the level of blood sodium in patients hospitalized for heart failure with water-sodium retention treated with loop diuretics and risk factors of low blood sodium.

METHODSWe selected 1 378 acute decompensated heart failure patients who visited Anzhen Hospital, and they are treated with loop diuretics, 259 patients with weight loses more than 1 kg in one week was enrolled in the final analysis, and divided into 3 groups: Group A (weight reduction between 1-3 kg), Group B (weight reduction between 3-5 kg) and Group C (weight reduction over 5 kg). Blood sodium, creatinine and uric acid were compared among groups and risk factors of low blood sodium were analyzed.

RESULTSBlood sodium was similar before and post loop diuretics treatment in Group A, and reduced in group B ((138.28 ± 3.73) mmol/L vs. (139.34 ± 3.66) mmol/L, P < 0.05) and in Group C((137.60 ± 4.07) mmol/L vs. (139.44 ± 4.12) mmol/L, P < 0.05). Forty-six (17.8%) patients developed hyponatremia post loop diuretics treatment. Duration of loop diuretics use was the independent risk infector for hyponatremia (OR = 1.191, 95%CI 1.010-1.385).

CONCLUSIONSLoop diuretics use is safe for treating hospitalized patients for heart failure with water-sodium retention and the risk of developing hyponatremia is low. Duration of loop diuretics use is the independent risk factor of hyponatremia.

OBJECTIVE: To observe the efficacy of allergen blocking nasal spray (ABNS) , combined with seawater spray (SS) and myrtol standardized capsules (MSS), in patients with rhinitis sicca. METHOD: Patients diagnosed as rhinitis sicca were randomly divided into 2 groups: ABNS+SS group and SS group. In ABNS+SS group, patients used ABNS and SS four times per day and MSS twice per day. In SS group, patients used the same medicine except ABNS. Both group were observed for 14 days. The visual analog scale (VAS) of dryness, the endoscopy evaluation score (EES) and the tolerability of the spray were compared between the 2 groups. RESULT: There were 30 patients included in each group. The VAS and EES were improved in both groups after 2 weeks' treatment. The improvement of VAS and EES in ABNS+SS group was significantly superior to SS group (VAS: P < 0.01, EES: P < 0.05). There were only 2 patients complaint of slight discomfort when using ABNS, which did not disturb the treatment. CONCLUSION There is good efficacy of allergen blocking nasal spray (ABNS), combined with seawater spray (SS) and myrtol standardized capsules (MSS), in patients with rhinitis sicca.

BACKGROUNDAt present, the most effective treatment for pulmonary alveolar proteinosis (PAP) remains whole-lung lavage in spite of the usually accompanying severe hypoxemia, which is expected to be prevented by hyperoxygenated solution improving oxygen supply during lavage. In this study, the efficacy and safety of the effect of hyperoxygenated solution were evaluated.

METHODSFive patients underwent whole-lung lavage over a 28-month period. Each lung was lavaged with hyperoxygenated (HO) and normal saline solution (plain lactated Ringer's solution, NO) randomly and alternatively until the reclaimed fluid was clear. Random number was generated by computer before every cycle of lavage. If the number was odd, the patient was assigned to receive a lavage cycle with hyperoxygenated solution (HO group, n = 109); if the number was even, normal saline solution was used (NO group, n = 115). Data of saturation of peripheral oxygen (SPO(2)), mean arterial pressure (MAP), central venous pressure (CVP), heart rate (HR) and end-tidal carbon dioxide tension (P(ET)CO(2)) were taken down at 0, 30, 60, 90, 120, 150, 180, 210 and 240 seconds from the beginning of the instillation of solution, and frequency and volume of unilateral lung lavage were also recorded. Time interval between the left and the right lung lavage was 1 week.

RESULTSNo patient was withdrawn from the study due to low SPO(2) or leakage. Oxygen pressure was (730.21 +/- 7.43) mmHg in the hyperoxygenated solution against (175.73 +/- 5.92) mmHg in the normal saline solution (P < 0.01). Compared with baseline, SPO(2) increased significantly as the instillation of solution began (P < 0.01), leveled for about 30 seconds (P > 0.05), and then decreased significantly to the lowest at the time of drainage (compared with 120 seconds or peak, P < 0.01). SPO2 was higher in HO group than in NO group (P < 0.01). There were no significant differences in MAP, HR, CVP and P(ET)CO(2) between HO group and NO group (P > 0.05) and also among different time points (P > 0.05).

CONCLUSIONDuring the lung lavage for pulmonary alveolar proteinosis, hyperoxygenated solution could significantly improve oxygen supply in comparison with normal saline solution without obvious side effects.

Thiazide is known to decrease urinary calcium excretion. We hypothesized that thiazide shows different hypocalciuric effects depending on the stimuli causing hypercalciuria. The hypocalciuric effect of hydrochlorothiazide (HCTZ) and the expression of transient receptor potential vanilloid 5 (TRPV5), calbindin-D(28K), and several sodium transporters were assessed in hypercalciuric rats induced by high calcium diet and vitamin D3. Urine calcium excretion and the expression of transporters were measured from 4 groups of Sprague-Dawley rats; control, HCTZ, high calcium-vitamin D, and high calcium-vitamin D with HCTZ groups. HCTZ decreased urinary calcium excretion by 51.4% in the HCTZ group and only 15% in the high calcium-vitamin D with HCTZ group. TRPV5 protein abundance was not changed by HCTZ in the high calcium-vitamin D with HCTZ group compared to the high calcium-vitamin D group. Protein abundance of NHE3, SGLT1, and NKCC2 decreased in the hypercalciuric rats, and only SGLT1 protein abundance was increased by HCTZ in the hypercalciuric rats. The hypocalciuric effect of HCTZ is attenuated in high calcium and vitamin D-induced hypercalciuric rats. This attenuation seems to have resulted from the lack of HCTZ's effect on protein abundance of TRPV5 in severe hypercalciuric condition induced by high calcium and vitamin D.
