Objective To evaluate the long-term results of partial internal sphincterectomy for the treatment of internal anal sphincter achalasia in childhood. Methods The clinical,radiographic,manometrical and histochemical data of 6 cases were reviewed retrospectively. All patients had received partial internal sphincterectomy and were followed-up for 2 to 8 years. Results All patients presented with severe constipation with or without soiling. No stenosis zone of intestine could be noted in 3 patients by barium enema examination. The rectoanal inhibition reflex on rectal balloon inflation was absent in all patients. The normal acetylcholinesterase activity on rectal biopsies was demonstrated by histochemical staining. Ganglion cells within internal anal sphincter was noted in all cases. On follow-up,all patients regained regular bowel habits and are not on any laxatives. Conclusion The long term results of partial internal sphincterectomy for the treatment of internal anal sphincter achalasia in childhood are satisfactory.

Objective Using infrared spectroscopy to analyze three kinds of lignum Chinese medicine to provide a theoretical basis for the establishment of medicinal overall quality evaluation system. Methods Functional groups identification, Fourier Transform-infrared spectroscopy(FT-IR) and the second derivative infrared spectroscopy (SD-IR) could be applicable to analyze and identify the overall chemical composition of three kinds of lignum Chinese medicine. Results The main chemical components of Aquilariae Lignum Resinatum (ALR), Dalbergiae Odoriferae Lignum (DOL) and Sappan Lignum (SL) were cellulose, lignin and aromatics. The main chemical compositions of Sappan Lignum (SL) were cellulose, lignin and aromatics. The differences in FT-IR and SD-IR of DOL and SL indicated that they had different aromatic compounds. Conclusion Infrared spectroscopy can be used as a simple and accurate quality control method of three kinds of lignum Chinese medicine.

Objective To Establish an evaluation system of the quality of life for Chinese liver and kidney transplant recipients,and develop a specialized scale to measure the quality of life (QOL)for such recipients preliminarily.Methods By combining subjective and objective methods,this study determined the evaluation system and created items of QOL scale based on literature analysis,Delphi method (expert consultation),interviews,and experience of researchers.Then,a nationwide clinical survey was conducted on 5 Level Ⅲ Class A hospitals.454 valid questionnaires were collected,including 153 from liver recipients,and 301 from kidney recipients.Subjective statistical methods such as critical Ratio method,correlation coefficient method,dispersion tendency method,and exploratory factor analysis were used for selection of questionnaire items.Results The study established an evaluation system of QOL for liver and kidney transplant recipients,including 4 primary indexes and 12 secondary indexes,and developed QOL scales that were appropriate for liver and kidney transplant recipients respectively.Conclusions The structure of QOL scale for liver and kidney transplant recipients was basically consistent with theoretical assumption.The QOL scale for patients showed good reliability and validity,therefore,it can fully reflect the quality of their life.

Objective To provide effective reference for quality analysis of the chemical composition and extraction of astragalus separation process by comparing the extract of astragalus and it’s IR spectra. Methods The saponins and flavonoids in astragalus were firstly extracted by the method of circumfluence with ethanol as solvent and the residue of ethanol-extraction was then used to extract polysaccharides by distilled water. Fourier transform infrared spectroscopy (IR) combined with second derivative infrared spectroscopy was applied to quickly identify astragalus herbs powder, water extraction of astragalus, astragalus alcohol extraction and water extraction of the residue of ethanol-extraction. Results The powder and 70% ethanol extract, 80% ethanol extract were around at 1 735 cm-1 (carbonyl stretching vibration absorption peak) has a weak, broad absorption, while the absorption peak was less obvious in boiling water extraction. So the maln components of astragalus water extraction are polysaccharides and also contaln a small amount of water-insoluble flavonoids. Alcohol extraction malnly contalns saponins and flavonoids, and flavonoid extract volume increases with increasing alcohol concentration in a certaln range.Conclusion This method can be a quick and easy identification for astragalus and it’s extraction for its chemical composition class, and provide the basis for further research quality.

Neurofibromatosis type 1（NF1）is one of the most common autosomal dominant disorders. The disease is caused by mutations in the NF1 gene，which can involve multiple systems and have a variety of clinical manifestations，including café au lait macules，lisch nodules，neuroglioma，autism spectrum disorder，learning difficulties，neurofibromas，and skeletal dysplasia，et al.In previous studies on the pathogenesis of NF1，most of them have focused on the regulation of the RAS signaling pathway by neurofibromin. In recent years，researchers start exploring pathways other than RAS signaling to explore the potential functions of neurofibromin. This article reviews the research progress on the pathogenesis of NF1 in recent years，aiming to provide new ideas for treatment.

Chondroitin sulfate (CS) is a sulfurated glycosaminoglycan, a major component of the extracellular matrix, widely distributed in skin, cartilage and vascular tissue. CS plays an important role in the physiological state regulation of articular cartilage, which affects tensile strength and elasticity of tissues by influencing aggrecan. Previous studies have shown that CS sulfate modification may be related to the growth and development disorders of cartilage tissue and the occurrence of osteoarticular diseases. At the same time, CS is also a common joint supplement, often used in the treatment of osteoarthritis and Kashin-Beck disease. In this paper, the research progress of CS sulfate modification characteristics in Kashin-Beck disease and osteoarthritis and the application of the preparation in the treatment of Kashin-Beck disease and osteoarthritis are reviewed, aiming to provide help for the investigation of the etiology of Kashin-Beck disease and the treatment of osteoarthritis and Kashin-Beck disease.
