It was the honor to participate in the exchange program between University of Malta and Soochow University focusing on Dementia care;gerontology and elderly rehabilitation care from September 2016 to January 2017. During those 5 months, as a nursing graduate student, the experience which made me a deeply impression is the point of view ofperson-centred carefrom the medical care I′ve seen in Malta. This essay combined with the exchange experience through clinical observation and practice at hospitals in Malta, is going to highlight the point of view of person-centred care. That can reflect on some shortages of domestic in the medical care environment in China, hoping for a morehumane, moreperson-centred, andperson in heartmedical care environment.

Objective To systematically study solvatomorphism of indomethacin and provide a scientific basis for the quality control of the solvated impurities in this drug. Methods By changing the recrystallization solvent, solvent volume, recrystallization temperature, time and pressure, nine solvates and four non-solvated forms were discovered and prepared. The differential scanning calorimetry (DSC), thermogravimetric analysis ( TGA), X-ray powder diffraction ( PXRD) and infrared spectrometry (IR) were introduced for characterization analysis. Furthermore, the test of influencing factors was used to explore the stability of solvate crystal form and the crystal transformation rules among them. Results Nine solvates were prepared, which including two solvates reported for the first time in this work. Results showed that crystal forms of the 9 solvates have different types or proportions of crystal solvents according to the various results of DSC, TGA, PXRD and IR. Moreover, the nine solvates prepared in this work were metastable crystal forms which could be transformed to non-medicinal forms. Conclusion The composition, thermodynamic property and transformation rule of all the solvates are elucidated in this work. In addition, an effective method for qualitative or quantitative analysis of these solvates was established. The standard graphs and data were used as basic data and scientific basis for the solvate control in the manufacturing of indomethacin.

Objective:To investigate the relationship between heart rate, blood pressure and autonomic nerve function in patients with obstructive sleep apnea hypopnea syndrome (OSAHS) after uvulopalatopharyngoplasty (UPPP).Methods:One hundred patients with OSAHS who underwent UPPP in Wuhan Central Hospital Tongji Medical College, Huazhong University of Science and Technology from July 2018 to July 2019 were selected.

OBJECTIVETo summarize the clinical manifestation and diagnosis of ganglioneuroma in spine and investigate the clinical effect of surgical treatment.

METHODSThe clinical data of 6 patients underwent a surgery for ganglioneuroma in spine from January 2008 to January 2015 were retrospectively analyzed. There were 4 males and 2 females, aged from 2 to 63 years old with an average of 34.6 years. The courses of disease were from 3 days to 17 years. Five patients complicated with superficial hypesthesia in correlative level of tumor, and the muscle strength under tumor plane had decreased at different levels, with the strength of grade II-IV. Two cases complicated with hypermyotonia and positive bilateral Hoffmann's and Babinski sign. Five cases were sporadic lesion in correlative spinal canal and one case complicated with the giant occupying lesion in thoracic cavity.

RESULTSSix operations had been performed including 5 en bloc and 1 subtotal resection. Postoperative pathological results showed tumor cells scattered or fasciculated inserted into Schwann cells in the stroma. In 2 patients complicated with radiculalgia before operation, 1 case was relieved and 1 was invariant after operation. All 4 patients with preoperative dyscinesia in the limbs obtained improvement after operation. All the patients were followed up from 0.3 to 6.8 years with an average of 2.5 years. At the final follow-up, according to ASIA grade, 5 cases were good and 1 case was invariant. During the follow-up, only 1 patient experienced chemoradiation because of merging ganglioneuroblastoma and receiving subtotal resection. No recurrence in other 5 cases.

CONCLUSIONGanglioneuroma is a benign and rare tumors in spine. Clinically, radicular pain and sensory-motor disorders are the main manifestations. Its diagnosis depends on pathological examination. Prognosis of surgical treatment is good.

Objective To explore the differences between normotrophic and hypertrophic scars of lip after the surgical repair of the unilateral complete cleft lip in density of microvessels and the pattern of angiogenesis.Methods Hypertrophic scars (n=11) and normotrophic scars (n=20) were collected after correction of deformity of the unilateral complete cleft lip,and the tissues were stained with haematoxylin and eosin,and immunostained with anti-CD34 antibody.The structure of scar was observed and the microvessels were counted according to the CD34 expression.Using ImageJ software,the capillary density and length of the major and minor axes were measured,and the major:minor axes ratio was calculated.Results By statistical analysis of the capillary density,the length of the major and minor axes and the major:minor axes ratio were measured;we clarified that there were more capillaries in hypertrophic scars (87.91 ± 5.95)/mm2 than in normotrophic scars (49.84 ± 7.05)/mm2,(P＜0.01),and the length of the major and minor axes of hypertrophic scars (38.36± 26.36)and (17.33±10.45) μm were longer than the normotrophic scars (13.77±9.56)and (9.00± 5.14) μm,(P＜0.05.) The major:minor axes ratio of hypertrophic scars (2.85±0.57) was higher than the normotrophic scars (2.85 ± 0.57) (P＜0.01).Conclusions The significant increase in the density of microvessels and the variation in the pattern and morphology of angiogenesis are related to the formation and development of scar after operation of upper lip.
