Association of intraoperative hypotension and severe postoperative complications during non-cardiac surgery in adult patients: A systematic review and meta-analysis.

Background: Intraoperative hypotension (IOH) is a common side effect of non-cardiac surgery that might induce poor postoperative outcomes. The relationship between the IOH and severe postoperative complications is still unclear. Thus, we summarized the existing literature to evaluate whether IOH contributes to developing severe postoperative complications during non-cardiac surgery.

Combined Effects of Electroacupuncture and Behavioral Training on Learning-Memory Ability and Event-Related Potential P300 in Rats with Mid/Advanced Cerebral Infarction.

Background: The effectiveness of the combination of electroacupuncture (EA) and behavioral training (BT) for mid/advanced cerebral infarction (M/ACI) and related mechanisms remains unclear. This study aimed to investigate the combined effects on the learning-memory ability and event-related potential P300 in rats with M/ACI.

Methods: Eighty rats with M/ACI were divided into Group Model (M), Group EA, Group BT, and Group EA-BT (n = 20) according to the random number with five healthy rats in Group Control (CON).

Feasibility and safety of magnetic-controlled capsule endoscopy system in examination of human stomach: a pilot study in healthy volunteers.

Objective: To assess the feasibility and safety of magnetic-controlled capsule endoscopy (MCE) system for examination of human stomach.

Methods: This pilot study enrolled 34 healthy volunteers. All subjects swallowed the MCE and gas-producing powder for gastric distention.

[Regulation effects of liuwei dihuang pill, jingui shenqi pill, jiangu erxian pill containing serums on adipogenic and osteogenic differentiation-related genes expressions in the differentiation process of preadipocytes to osteoblasts].

Objective: To study the effects of Chinese medical recipes for invigorating Shen on rat bone marrow mesenchymal stem cells (BMSCs)-derived preadipocytes' differentiation to osteoblasts.

Methods: The BMSCs were cultured using whole bone marrow adherence wall method. The BMSCs were induced to preadipocytes by classic chemical method.

[Basic rules and characteristics of acupoint application therapy based upon data mining].

Objective: To analyze the basic characteristics of effects of acupoint application therapy in order to guide clinical decision better.

Methods: A database on acupoint application therapy was established first by collection, sorting, screening, recording, collation, data extraction, and statistical analyses of the related literature published in recent 60 years, and using modern computer system. Then, its predominant indications and application rules in clinical practice were analyzed using data mining techniques.

[Acupoint catgut-embedding therapy: superiorities and principles of application].

Objective: To analyze the superiorities of acupoint catgut-embedding therapy, discuss its law of clinical application and provide scientific decision-making for clinical treatment.

Methods: Literatures on acupoint catgut-embedding therapy in the recent 40 years were selected, input, examined and verified, picked up and analyzed by establishing database with the modern computer technology.

Results: (1) One thousand and seventy-five literatures were input.

[Research on characteristics of different clinical conditions treated by red-hot acupuncture needle based on data mining needle].

Objective: To analyze the regularities and characters of clinical application of red-hot needle therapy in ancient and modern literature of Chinese medicine by using data mining techniques, so as to provide a reference for study on the specificity of efficacy of red-hot needle therapy.

Methods: Sample data was collected from some medical books, medical cases, reports of modern journals for calculating frequent item sets by using methods of association rules of data mining. Then, the collected data was extracted, sorted out, and summed up by using our newly developed literature database platform of red-hot needle therapy in order to find out the most suitable indications of this therapy in clinical practice.

[Ecological stability on biological removal of iron and manganese filter under poor nutritional conditions].

To supply necessary bacteria and available nutrients, a method of returning backwashing wastewater to the bio-filter for removal of iron and manganese was used. The ecological stability of bio-filter was investigated from 3 aspects: iron and manganese removal efficiency, micro-ecological characteristics and the quantity distribution of dominant bacteria. The results indicated that, the bio-filter held strong antishock loading capability, when the system was operated at high filtration rate (10-13.

UV-catalytic treatment of spent caustic from ethene plant with hydrogen peroxide and ozone oxidation.

The performance of UV/H2O2, UV/O3 and UV/H2O2/O3 oxidation systems for treating spent caustic from an ethylene plant was investigated. In UV/H2O2 system, with the increase of H2O2 dosage, removal efficiencies of COD and the ratio of biochemical oxygen demand (BOD) to chemical oxygen demand (COD) of the effluent were increased and a better performance was obtained than the H2O2 system alone. In UV/H2O2 system, removal efficiency of COD reach 68% under the optimum condition, and BOD/COD ratio was significantly increased from 0.
