OBJECTIVE：To i nvestigate the clini cal ch aracteristics of anaphylactic shock induced by piperacillin and its compound preparation ，and to provide reference for prevention and treatment of the severe ADR. METHODS ：A case of anaphylactic shock induced by piperacillin and sulbactam were analyzed in our hospital ，meanwhile ADR literatures about piperacillin alone and its compound preparation-induced anaphylactic shock were collected from Medline ，CNKI，Wanfang database and VIP during the inception to Jul. 2020. Gender and age of patients ，allergic history ，primary disease and treatment ，skin test ， administration route and dosage of piperacillin and its compound preparation ，occurrence time and main manifestations of anaphylactic shock ，treatment measure and prognosis were analyzed ，then prevention and treatment suggestions were put forward. RESULTS：The patient in this case was transferred to the ICU after partial hepatectomy. The use of piperacillin and sulbactam to prevent postoperative infection caused anaphylactic shock. A total of 28 literatures about anaphylactic shock induced by piperacillin and its compound preparations were collected from the database （involving 28 patients）. Among totally 29 patients，there were 12 male and 17 female；the majority of patients were 50-59 years old （6 cases，20.69％）. Three patients had allergic history （food， latex gloves ，etc.），and most of the primary diseases were infectious diseases or the drug used in perioperative period. Skin tests were carried out in 22 patients（75.86％）before medication and the results were negative. The possible allergenic drugs of 27 cases which were administered by intravenous route included piperacillin ，piperacillin sulbactam and piperacillin tazobactam. The dosage was different according to the primary disease and severity. 14 patients（55.56％）developed anaphylactic shock within 5 minutes after drug exposure. The main symptoms were systemic allergic reaction ，mainly involving the circulatory system. Except for two death cases ，the other patients ’symptoms were relieved after treatment. CONCLUSIONS ：Allergic history and skin test results may have limitation in predicting anaphylactic shock induced by piperacillin and its compound preparation. Close monitoring needs to be taken in patients during these medications. Rescue therapy should be prepared in advance and countermeasures need to be carried out promptly in case of anaphylactic shock.

Objective:To investigate the features of volume, distribution, grading and staging of prostate cancer(PCa)examined via whole-mount histopathology in transitional PCa.Methods:A total of 129 PCa patients undergone radical prostatectomy(RP)between July 2017 and March 2020 whose whole-mount prostate specimens were prepared after surgery were retrospectively studied.Pathological data on tumor locations, diameters and classification of the International Society of Urologic Pathology(ISUP), radiological data on regions of interest(ROI)and scores of the Prostate Imaging and Reporting Data System(PI-RADS v2)were recorded.The results of pathological whole-mount sections and prostate imaging were compared, and the characteristics and detection rates of lesions in different prostate regions were analyzed.Results:Of all 129 prostate specimens from RP, a total of 213 PCa lesions were detected through whole-mount histopathology.There were 21(9.9%)lesions involving both the peripheral zone(PZ)and the transition zone(TZ), with an average diameter of(2.82±0.71)cm.Of all lesions, 85(39.9%)involved PZ and 107(50.2%)involved TZ, with an average diameter of(1.36±0.81)cm and of(1.60±0.94)cm, respectively.The percentage of lesions involving TZ was higher than that lesions involving PZ, with larger diameters( P<0.05). Of 64 patients with complete MRI data, 105 PCa lesions were detected histopathologically by using whole mount sections, while 75 PCa lesions were detected by MRI, with a statistical difference( P<0.05). For lesions≥1.0 cm or lesions with an ISUP grade group≥2, the detection rate of MRI was lower in TZ lesions( P<0.05). Conclusions:PCa lesions within TZ account for a large proportion and have a relatively large tumor dimeter.PCa lesions within TZ are more likely to be missed in clinical examinations and on MRI, and clinicians should pay close attention during diagnosis and treatment.

Objective: To investigate the significance of circulating tumor cells (CTC) in squamous cell carcinoma of the head and neck (HNSCC). Methods: Twenty-four patients with HNSCC treated between October 2016 and July 2017 in our department were selected (experimental group), including 23 males and 1 females, aged 47-81 years. There were 14 cases of squamous cell carcinoma of larynx and 10 cases of hypopharynx, including I-Ⅱ stage (5 cases) and Ⅲ- Ⅳ stage (19 cases). All patients were primary and/or relapsed after treatment. Nine healthy volunteers were selected as control group. A novel in vivo capture technique (CellCellector system) was used to detect CTC. SPSS23.0 was used for statistical analysis. Results: The total capture rate of CTC in patients with HNSCC before treatment was 70.8% (17/24), with 40% (2/5) for patients at I-Ⅱ stage, and 78.9% (15/19) for patients at Ⅲ- Ⅳ stage, and was 0 in patients of control group. The total capture rate of CTC in patients with HNSCC after treatment was 50% (8/16). There was no significant correlation between CTC and age, sex, location of tumor or lymph node metastasis (P>0.05). CTC was related to tumor staging and tumor differentiation (P<0.05). The positive rate of EGFRVⅢ in CTC was 26.3% (5/19). Conclusions The CellCollector system is a very efficient way of detecting CTC, and CTC plays an important role in the occurrence, progression and metastasis of HNSCC.

Objective To investigate the nursing effects of Sanyrene in the drug extravasation induced by intravenous drip of potassium chloride in adults. Methods A total of 72 patients with drug extravasation caused by intravenous drip pf potassium chloride in Chinese PLA General Hospital from April 2016 to April 2017 were selected as study objects and divided into the control group and the experimental group according to the order of admission, 36 cases respectively. Patients in the control group were treated with magnesium sulfate, while patients in the experimental group were treated with Sanyrene. After the treatment, both groups were given comprehensive nursing intervention. The total clinical therapeutic efficiency, incidence of complications and patients' nursing satisfaction rate were compared between two groups. Results The total clinical therapeutic efficiency and patients' satisfaction rate in the experimental group were significantly higher than those in the control group (P< 0.05). The incidence of complications in the experimental group was significantly lower than that in the control group (P<0.05). Conclusions The application of Sanyrene in the treatment of drug extravasation induced by intravenous drip of potassium chloride in adults has significant therapeutic effect. The combination of Sanyrene with comprehensive nursing intervention can help to shorten the clinical symptom remission time, improve nursing satisfaction, and reduce the incidence of complications of patients, which is worthy of clinical promotion.

Objective:To investigate the effects of Mor-platin, a novel mitochondrial platinum complex, on proliferation and migration of human hepatoma carcinoma HepG2 cells. Methods:Cell counting kit-8 (CCK-8) assay was used to analyze cell proliferation of Mor-platin and classic anticancer drugs, particularly cisplatin, in HepG2 cells. A laser confocal microscope was used to observe whether Mor-platin can target mitochondria. The morphological changes in cellular mitochondria after treatment with Mor-platin were ob-served on a transmission electron microscope. Cell apoptosis was measured by flow cytometry, and cell invasion was evaluated by three-dimensional tumor spheroid model. Results:Mor-platin can inhibit cell proliferation and is dose dependent. The half inhibitory concentration (IC50) of Mor-platin is lower than that of cisplatin. Laser confocal images showed that Mor-platin can target cell mito-chondria and enrich cell mitochondria. Transmission electron microscopy images showed that cell mitochondrial morphology changed after Mor-platin treatment. Furthermore, cell mitochondrial membrane is incomplete and mitochondrial cristae are reduced. Cell apoptosis caused by Mor-platin is dose dependent. The three-dimensional tumor spheroid model showed that the cell areas of the group subjected to Mor-platin treatment are smaller than those of the control group. Conclusion:Mor-platin can target cell mitochon-dria, change the cell mitochondrial morphology, inhibit cell proliferation, and thus promote cell apoptosis. It also showed better anti-cancer effects than cisplatin. Furthermore, Mor-platin can inhibit three-dimensional tumor spheroid invasion. These results suggest that Mor-platin is a potential antitumor drug.
