[Guideline for clinical comprehensive evaluation of Chinese patent medicine (2022 version)].

Currently,the research or publications related to the clinical comprehensive evaluation of Chinese patent medicine are increasing,which attracts the broad attention of all circles. According to the completed clinical evaluation report on Chinese patent medicine,there are still practical problems and technical difficulties such as unclear responsibility of the evaluation organization,unclear evaluation subject,miscellaneous evaluation objects,and incomplete and nonstandard evaluation process. In terms of evaluation standards and specifications,there are different types of specifications or guidelines with different emphases issued by different academic groups or relevant institutions.

Efficacy and Safety of Modified Yupingfeng Nasal Spray in Controlling the Recurrence of Persistent and Moderate-Severe Allergic Rhinitis: Study Protocol for a Multicenter, Open-Label, Randomized, and Parallel-Arm Trial.

Background: Recurrent episode of allergic rhinitis (AR) is one of the leading illnesses that affects patients. However, there is little research evidence to support pharmacotherapy for AR recurrence. Therefore, this study was designed to explore the efficacy of pharmacotherapy in the control of the recurrence of AR.

Conlecs: A novel procedure for deriving the concentration limits of chemicals outside the criteria of human drinking water using existing criteria and species sensitivity distribution based on quantitative structure-activity relationship prediction.

Water quality criteria (WQC) for an increasing number of emerging chemicals need to be developed to protect human health and biological safety. Existing species sensitivity distribution (SSD) methods can only be used to help establish WQC for ecological protection, and cannot be extended to the protection of human beings from various hazards. In this study, a novel procedure called Conlecs is proposed to derive the concentration limits (ConLs) of pesticides outside the criteria for human drinking water (CHDW) using the existing criteria of pesticides and SSD integrated with the toxicity prediction achieved through robust QSAR models.

Immobilization of uranium into magnetite from aqueous solution by electrodepositing approach.

Immobilization of uranium into magnetite (FeO), which was generated from metallic iron by electrochemical method, was proposed to rapidly remove uranium from aqueous solution. The effects of electrochemical parameters such as electrode materials, voltage, electrode gap, reaction time and pH value on the crystallization of FeO and uranium removal efficiencies were investigated. More than 90% uranium in the solution was precipitated with FeO under laboratory conditions when uranium concentration range from 0.

[Contamination and ecological risk assessment of polycyclic aromatic hydrocarbons in water and in Karst underground river catchment].

Water samples in Laolongdong underground river catchment were collected to determine the concentration, compositional profiles, and evaluate ecological risk of 16 priority polycyclic aromatic hydrocarbons (PAHs). PAHs were measured by GC/MS. The total concentrations of 16 PAH ranged from 81.

[Hydrogeochemical characteristics of a typical karst groundwater system in Chongqing].

The two-year hydrologic process, hydrochemistry, and a portion of deltaD, delta18O of both the surface water at the inlet and the groundwater at the outlet, were investigated to identify the spatial and temporal variations of hydrogeochemistry in the Qingmuguan karst groundwater system. Research results show that there are wet and dry periods in the groundwater system owing to the striking influence of seasonal rainfall. The evolution of the chemical compositions in the groundwater is significantly influenced by the water and rock interaction, anthropogenic activities and rainwater dilution.

[Clinical and pathologic features of melanocytic lesion of the central nervous system].

Objective: To investigate the clinical and pathologic features of melanocytic lesion of the central nervous system.

Methods: We analyzed the clinical features, neuroimages, and operational and neuropathological findings of 2 patients of neurocutaneous melanosis and 4 patients of primary leptomeningeal melanoma.

Results: All the 6 patients had the common clinical features of intracranial hypertension and epilepsy.

[Genetic features of EEG abnormality in children with Tourette syndrome].

Objective: To investigate the biogenetic significance of EEG abnormality in Children with Tourette syndrome (TS) and their parents.

Methods: EEG monitoring was carried out for 2 hours in 25 children with TS and their parents.

Results: The rate of EEG abnormality was significantly higher than the incidence of tic disorders in parents of TS children.
