Diagnosis and treatment of 38 cases of tsutsugamushi disease / 中国生化药物杂志

Objective To deepen the understanding of the clinical features of tsutsugamushi disease, in order to improve the diagnosis and treatment level. Methods The clinical data of 38 patients with tsutsugamushi disease were analyzed retrospectively in Shengzhou People 's Hospital from June 2015 to October 2016. Results All patients had persistent fever, were found eschar; 5 cases of elevated white blood cells, decreased in 10 cases, 23 cases of normal, C-reactive protein increased in 32 cases, 19 cases of thrombocytopenia, alanine aminotransferase increased in 29 cases, 22 cases of serum sodium, 19 cases of hypokalemia, 38 cases of serum albumin decreased; 26 cases of rash, 23 cases of pneumonia, inguinal lymph nodes in 22 cases, complicated by septic shock, respiratory failure in 3 cases. Conclusion The clinical symptoms of tsutsugamushi disease are diverse and lack of specificity. In patients with persistent fever in summer and autumn, it is necessary to guard against tsutsugamushi, and the eschar is found in time. The diagnosis and treatment is reduced and the misdiagnosis rate is reduced.

[Impacts of alkaline thermal treatment on characteristics of sludge from sewage treatment plant].

Alkaline thermal treatment is an important pretreatment method for sewage sludge. In this paper, in order to optimize the alkaline thermal treatment conditions for sludge pretreatment, four pretreatment parameters ( sludge concentration, pH, temperature and treatment time) were investigated through orthogonal experiments to determine their effects on the sludge disintegration, sludge concentration and sludge morphology of sewage sludge. The experimental results showed that the significance of the four factors on sludge characteristics was in the order of pH > temperature > treatment time > sludge concentration. Additionally, the optimal conditions of the four factors for the release of soluble chemical oxygen demand (SCOD) of unit sludge and decrease of sludge concentration were as follows: 36.55 g x L(-1), pH 12.45, 175 degrees C and 60 min. While the optimal conditions for the decrease of particle size and fractal dimension were 36.55 g x L(-1), pH 12.5, 175 degrees C and 45 min.

[Mechanism of the organic pollutant degradation in water by hybrid gas-liquid electrical discharge].

The method of hybrid gas-liquid electrical discharge was investigated for the removal of phenol. The results indicate that this new method can remove phenol in water effectively. The removal rate increases with increasing voltage and air aeration. The production quantity of H2O2 and O3 is measured respectively in the discharge region and the production quantity increases with increasing of voltage and air aeration. The energy consumption analysis indicates that with increasing the voltage, the increase extent of the phenol removal rate is smaller than the energy's, so the increase of energy efficiency is very small. Air aeration increases the energy consumption. At the same time, a considerable part of energy in the overall input energy makes the temperature of the solution increase, and more energy is transformed into heat, which leads to the waste of energy.

Removal of phenol by activated alumina bed in pulsed high-voltage electric field.

A new process for removing the pollutants in aqueous solution-activated alumina bed in pulsed high-voltage electric field was investigated for the removal of phenol under different conditions. The experimental results indicated the increase in removal rate with increasing applied voltage, increasing pH value of the solution, aeration, and adding Fe2+. The removal rate of phenol could reach 72.1% when air aeration flow rate was 1200 ml/min, and 88.2% when 0.05 mmol/L Fe2+ was added into the solution under the conditions of applied voltage 25 kV, initial phenol concentration of 5 mg/L, and initial pH value 5.5. The addition of sodium carbonate reduced the phenol removal rate. In the pulsed high-voltage electric field, local discharge occurred at the surface of activated alumina, which promoted phenol degradation in the thin water film. At the same time, the space-time distribution of gas-liquid phases was more uniform and the contact areas of the activated species generated from the discharge and the pollutant molecules were much wider due to the effect of the activated alumina bed. The synthetical effects of the pulsed high-voltage electric field and the activated alumina particles accelerated phenol degradation.
