Abstract: Objective　To investigate the clinical and laboratory characteristics of pulmonary infection caused by Nocardia otitidiscaviarum. Methods　The clinical data of a patient with pulmonary infection caused by Nocardia otitidiscaviarum were reported, and the clinical characteristics, laboratory characteristics and drug sensitivity of pulmonary infection caused by Nocardia otitidiscaviarum were summarized in combination with the relevant literature at home and abroad from January 2010 to December 2022. Results　A 67-year-old female patient was admitted to the hospital on June 30, 2020 because of "repeated chest tightness and shortness of breath for 3 years, aggravated cough, expectoration and fever". The sputum, alveolar lavage fluid and blood of the patient were collected for culture, and the detected pathogenic bacteria were identified. There are pathogenic bacteria growing in sputum and alveolar lavage fluid, which are identified as Nocardia otitidiscaviarum by Autof ms mass spectrometer. According to the results of pathogenic bacteria and the patient's condition, meropenem combined with compound sulfamethoxazole tablets were given anti-infection treatment, and the patient's condition improved and discharged. Conclusion　The clinical manifestations and imaging features of nocardiosis are lack of specificity, and are prone to misdiagnosis and missed diagnosis. Etiology is the key to disease diagnosis, and clinical examination and culture should be conducted in time.

The study is to develop a method to determine 3 batches leaves of Nauclea officinalis and stems of N. officinalis by HPLC. The differences between strictosamide contents and fingerprints was compared, then chromatographic peak of fingerprints was validated with the assistance of LC-MS. The strictosamide contents in stems of N. officinalis were higher than leaves of N. officinalis. The main chemical composition in leaves of N. officinalis and stems of N. officinalis were alkaloid which revealed by LC-MS. There are 7 chemical compositions were same between them, but the chemical composition in leaves of N. officinalis is more than stems of N. officinalis. This provides a scientific basis for the development of the potential medicinal value of leaves of N. officinalis and the sustainable utilization of N. officinalis.

BACKGROUNDWith a trend that renal tumors are being detected at an earlier stage, classical radical nephrectomy is being reconsidered. More conservative techniques are being proposed. To clarify the indication for synchronous adrenalectomy in radical nephrectomy for renal cell carcinoma which has been questioned since the 1980s, this study evaluates the role of adrenalectomy and recommends a new indication for adrenalectomy in renal cell carcinoma.

METHODSA systemic search was performed, using PubMed and Google Scholar, of all English language studies published up to March 2012 that compared adrenalectomy with adrenal-sparing surgery, in surgery for renal cell carcinoma. We assessed preoperative imaging for adrenal involvement and the relationship of tumor location with adrenal metastases. Twenty-one studies (20 retrospective and 1 prospective) involving 11 736 patients were included.

RESULTSThe mean incidence of ipsilateral adrenal involvement from renal cell carcinoma was 4.5%. Synchronous adrenalectomy did not alter survival (hazard ratio (HR) = 0.89, 95% confidence interval (CI) 0.67 - 1.19, P = 0.43; odds ratio (OR) = 1.10, 95%CI 0.84 - 1.44, P = 0.49). Upper pole tumors were not associated with a higher incidence of ipsilateral adrenal metastases. Pooled preoperative imaging: sensitivity, specificity, positive predictive value and negative predictive value were 92% (95%CI 0.84 - 0.97), 95% (95%CI 0.93 - 0.96), 71.6% and 98.5% respectively.

CONCLUSIONSAdrenal involvement from renal cell carcinoma is rare, even in advanced tumours. Synchronous adrenalectomy does not offer any benefit, even for "high risk" patients. We suggest that only patients with a positive preoperative adrenal finding on preoperative imaging for a solitary adrenal metastasis should undergo adrenalectomy as part of the radical nephrectomy.
