Objective: To objectively evaluate the short-term and long-term efficacies of arthrolysis under brachial plexus anesthesia in treating adhesive capsulitis of the shoulder (ACS). Methods: One hundred patients diagnosed with ACS were divided into two groups using the random number method. The two groups both received same active rehabilitation exercises. Besides, 55 cases in the treatment group were given one session of arthrolysis under brachial plexus anesthesia, and 45 cases in the control group were given tuina treatment. Changes in the visual analog scale (VAS) score, Melle score and pressure pain index were observed 1 month and 3 months after treatment. The therapeutic efficacies were also compared. Results: The total effective rate was 96.4％ at the 1-month follow-up and 96.4％ at the 3-month follow-up in the treatment group. The total effective rate was 33.3％ at the 1-month follow-up and 28.9％ at the 3-month follow-up in the control group. There were significant differences between the two groups comparing the total effective rate at the two time points (both P<0.05). The scores of VAS, Melle and pressure pain were significantly different at the 1-month and 3-month follow-ups from those before treatment in the treatment group (all P<0.05); the three scores did not show significant differences at the 1-month and 3-month follow-ups compared with those before treatment in the control group (all P>0.05). Conclusion: Based on the active rehabilitation exercises, one session of arthrolysis under brachial plexus anesthesia can release the adhesion and restore the range of motion and function of shoulder joint in ACS patients. It is superior to rehabilitation exercises plus tuina treatment comparing both short-term and long-term efficacies.

Objective To explore the clinical and pathologic features of Langerhans cell histiocytosis(LCH).Method Thirty-eight cases of LCH from both in hospital and outpatient department in dermatology and pediatry department from Jan.1991 to Jun.2006 were analyzed about the features of clinic,pathology and immunohistochemistry.Results The mean age of onset was 2.18 years old.The male /female ratio was 1.71.Skin lesions occurred in 78.9% of the patients.Among them,68.5% were as the first manifestation.The eruptions mainly distributed on trunk,90% of them presented as hemorrhagic maculopapules,nevertheless,3.3% of the eruptions showed as crust with hilar depression,which was similar to pityriasis lichenoides etvarioliformis acuta.Fever,hepatomegalia and splenomegia occurred in patients at a rate of 60.5%,68.4%,55.3% respectively.Thirty-one point six percent of the patients had got lymphadenectasis,the neck and inguinal lymph nodes were the common site to be affected.Ossature involvement occurred in 31.6% of the patients,which 8.3% got multiple injuries,howe-ver,91.7% got a solitary bone involved.Skull was the main site to be injured,else were lumbar,humerus,hipbone,an so on.Respiratory tract,auditory canal,mucosa were also the sites involved in this disease,but the incidence rate was lower than 10%,respectively.The laboratory data showed that 81.3% of the patients were anaemia,60.7% with abnormal subgroup of T-cell,and 32.1% positive for EBV-IgG.The skin histopathology data of 26/30 cases revealed that lichenoid infiltrates of Langerhans cells confined to the upper dermis.Cytologic features were cells with abundant eosinophilic cytoplasms,and longitudinally grooved or reniform nuclei.Lymphocytes and a few eosinophils also could be seen.Four cases of thirty showed that the proliferative Langerhans cells were with pale cytoplasms,besides,there were numerous eosinophils,and sometimes a few multinucleate cells were scattered.The immunity test of 20 cases of thirty displayed that CD1a(+)S100(+)KP-1(-).Biopsy of lymphaden and tumor of the skull of the rest 8 patients were all diagnosed as eosinophilic granuloma through both hematoxylin and eosin-stained section and immune marks.Conclusions Multiple systems can be involved in LCH.Hemorrhagic maculopapules,fever and splenohepatomegalia are common presentations in this disease.The morphous of nucles of histiocytes is particular,and to diagnose definitely,both CD1a(+) and S-100(+) are needed.

Twelve cases of Bartter's syndrome were reported and reviewed retrospectively.Usually vomiting was the first sympton in children,while fatigue was common in adults.Bartter's syndrome was characteristic of hypokalemia,metabolic alkalosis,elevations of plasma renin activity,serum angiotersinⅡand aldosterone and juxtaglomerular apperatus hyperplasia.Supplementation of potassium choloride was the main manner of therapy.

Taking application of some isolation and purification technologies, such as solvent extraction, preliminary solvent isolation, column chromatographies over silica gel and Sephadex LH-20 gel and preparative HPLC, 10 compounds were obtained from Gynura nepalensis cultivated in the suburban area of Beijing. Their structures were identified by spectroscopic methods and comparison with literature as (3R) -3-hydroxy-β-ionone (1), (3S,5R, 6S, 7E) -5, 6-epoxy-3-hydroxy-7-megastigmen-9-one (2), (+) -boscialin (3), 3, 6-trans-3-hydroxy-α-ionone (4), 3, 6-cis-3-hydroxy-α-ionone (5), 3, 4-cis-3, 4-dihydroxy-β-ionone (6), ethyl caffeate (7), loliolide (8), 1H-indole-3-carbaldehyde (9), and 3-(hydroxyacetyl)indole (10), respectively. All compounds were isolated from the title plant for the first time, and with compounds 1, 2, 4-7, 9 and 10 being isolated from Gynura species for the first time. Structurally, the above compounds 1-6 belong to C13 nor-sesquiterpenoids, sharing the same carbon skeleton of megastigmane. According to this study, they are one of major kinds of chemical constituents of Gynura nepalensis and have important reference value for the investigation on phytotaxonomy of this species.

In order to improve the sharing of DICOM, a proposal is offered to introduce XML into DICOM on the SPIE 2005 and in this way, better readability and expansibility of DICOM files have been achieved. On this basis, the DICOM data structure is improved further by replacing the one-dimension linear data structure with multilayer tree-shaped data structure. And thus the nesting and dependence relationships between information object and data elements are much clearer and it is more convenient and easy to browse DICOM image files.

RESULTSAfter treatment, serum T3 increased and TSH decreased in the treatment group as compared with the control group (P < 0.05).

CONCLUSIONAuricular acupuncture combined with iodine salt can promote reduction of endemic goitre or elimination, and effectively regulate synthesis and metabolism of thyroid hormones.

OBJECTIVE: To establish the fingerprint of Xianling Gubao Capsules (XLGB) by multi-wavelength HPLC-UVD-ELSD and determine the main representative components simultaneously, in order to provide reference for the overall quality control of XLGB.METHODS: The separation was developed on Poroshell 120 EC-C18 column (4.6 mm×100 mm, 2.7 μm) by gradient elution with methanol-water at 240, 270 and 334 nm, the temperature of drift tube was maintained at 105 ℃ and the carrier gas flow rate was 2.0 L•min-1. An HPLC-UVD-ELSD fingerprint of XLGB was set up, and 15 batches of XLGB were evaluated by similarity assay. Furthermore, the contents of the main representative components were determined on the premise of small disparities between batches. RESULTS: The multi-wavelength HPLC-UVD-ELSD fingerprint of XLGB was established with good separation, and six chemical components were determined simultaneously. Thirty-one main characteristic peaks from six herbs of XLGB were chemically identified and 26 main characteristic peaks were assigned to individual herbs. The similarity of 15 batches of XLGB was about 0.943 to 0.997. Moreover, good linear relationships were found (r=0.999 0-0.999 6), and the average recovery rates were 98.5%-104.9%. CONCLUSION: The method can be used for the overall quality control of XLGB with good specificity and high efficiency and is close to the actual production, which is promising to be further improved to be used as an industry internal control standard.
