Objective To analyze the color Doppler ultrasonography of trauma-caused deep venous free-floating thrombus(FFT)of lower limbs,discuss the relations between sonography and the prognosis. Methods Clinical data and color Doppler ultrasound examination results of 130 cases with trauma-caused deep venous FFT of lower limbs were retrospectively analysed.Univariate analysis was conducted to identify the statistically significant factors of patients' prognosis,non-conditional logistic regression analysis was performed to analyse the independent prognostic factors of FFT.Results The non-conditional logistic regression analysis showed that the position of FFT,thrombosis edge definition,floating degree and the volume of detouring blood around the thrombus were independent factors of patients'prognosis(P <0.05). The FFT prognosis of iliofemoral vein was more likely to be fixed than the FFT prognosis of popliteal vein. The FFT prognosis with blurring edges was more likely to be fixed.The more obvious the floating degree of FFT,the higher chance that the FFT prognosis is recanalized.More detouring blood flow around FFT indicated more possibilities that the prognosis could be recanalized.Conclusions The color Doppler ultrasound is able to evaluate the relations between the deep venous free-floating thrombus of lower limbs and prognosis of the patients,which is beneficial for early detection and early treatment,as well as reducing mortality and disability resulted from deep venous thrombus during the orthopaedic perioperative period.

OBJECTIVE: To observe the effects of sleeping body posture on sleeping structure and respiratory events in patients with OSAHS. METHOD: We assessed the sleeping body position, the sleeping structure, position specific AHI and the Epworth Sleepiness Scale (ESS) in a total of 80 patients with Positional OSAHS. The patients were grouped according to AHI: mild OSAHS (5 < or = AHI <15), moderate (15 < or = AHI < 30) and severe (AHI > or = 30). The polysomnography data and clinical characteristics were compared between each group. RESULT: The severe OSAHS group, when compared with the mild and the moderate ones, had a significant different in REM%, NREM%, NREM LSaO2, RDI, S-AHI and L-AHI due to posture (P < 0.05). The severe and the mild OSAHS groups had significant different in MSaO2, LSaO2 due to posture (P < 0.05). The moderate and the mild OSAHS group had significant different in LSaO2, REM LSaO2 and RDI (P < 0.05). In all mild, moderate and severe groups, the LT% were higher than ST%, but the difference was not significant (P > 0.05). For mild-to-moderate groups, there was no correlation between the ESS and the AHI for any position different (P > 0.05). For severe group, the ESS was significantly correlated with L-AHI (r = 0.551; P < 0.01); the REM L-AHI and NREM L-AHI was also significantly correlated with ESS of severe group (r were 0.516 and 0.528, P < 0.01). CONCLUSION The L-AHI, NREM L-AHI, REM L-AHI and NREM LSaO2 were considered to monitor the stability of OS-AHS, while REM LSaO2 were consider to clarify the severity of OSAHS.

Objective To examine the association of urinary neutrophil gelatinase-associated lipocalin(NGAL) and interleukin 18(IL-18) with acute kidney injury (AKI) in patients after cardiac surgery. Methods Thirty-three patients undergone cardiac surgery were divided into AKI group and non-AKI group according to the AKI criteria. The Scr, urinary NGAL and IL-18 were measured at different time points. Results Nine of 33 patients (27.27%)developed postoperative AKI, and Scr concentration in AKI group reached its peak within 12-48 hours after cardiac surgery. Urinary concentrations of NGAL and IL-18 at 2 h and 4 h after cardiac surgery were significantly higher than those before operation in AKI patients (P<0.01). The urinary concentrations of NGAL at each time point and that of IL-18 at 2 h and 4 h after cardiac surgery in AKI patients were significantly higher than those in non-AKI patients. After correction by urinary creatinine, the differences of NGAL/Ucr and IL-18/Ucr ratios were still significant (P< 0.01). For concentrations of urinary NGAL, IL-18 and ratios of NGAL/Ucr, IL-18/Ucr at 2 h after surgery, sensitivities and specificities were good with cutoff values at 250 μg/L, 250 μg/mmol and 1800 ng/L, 1800 ng/mmol, respectively. Urinary concentration of NGAL at 2 h after cardiac surgery was positively correlated with Scr at 12 h postoperation in AKI group (r=0.638, P<0.05).Conclusions The incidence of AKI in patients after cardiac surgery is quite high. Urinary concentrations of NGAL, IL-18 and ratios of NGAL/Ucr, IL-18/Ucr at 2 h after cardiac surgery are the early diagnostic markers for AKI, among which urinary NGAL/Ucr is the most sensitive one.

OBJECTIVETo prepare monoclonal antibodies of mice anti-human sperm protein 22 (SP22) and to identify their specificities.

METHODSBALB/c mice were immunized with human SP22, monoclonal antibodies were prepared by hybridoma technique and the sensitivity and specificity of SP22 McAb were investigated by ELISA and Western-blot assay, respectively. The distribution of human SP22 in sperm were shown by immunohistochemistry.

RESULTSThree strains of hybridoma cells were obtained, with the affinity constant (K) of 1.0 x 10(7) L/mol and the titers were 1:10(3) and 1:3,200 in the mixed supernatant of cell cultures and abdominal dropsy, respectively. IgG isotype of the antibody was identified as IgG1. Western blot demonstrated that there was a specific recognition between human SP22 and the obtained monoclonal antibody. Immunohistochemistry displayed that human SP22 mainly distributed on the acrosome surface of human sperm.

CONCLUSIONThe monoclonal antibodies of anti-human 22 was prepared by the technique of hybridoma cell has higher titer and specificity, which can combine specially with the SP22 protein on the surface of human sperm.

The paper reported an investigation of the pharmacokinetics of SN-38 (7-ethyl-10-hydroxy-camptothecin) in rats and the tissue distribution in mice after injection of irinotecan hydrochloride nanoparticles (CPT-11) via tail veins. An LC-MS/MS method was established to determine the concentrations of SN-38 in whole blood of rats and in different tissues of mice. The pharmacokinetics and tissue distribution of SN-38 were compared after the intravenous injection of CPT-11 NPs and CPT-11 solution. Compared with irinotecan solution, the elimination half-life of SN-38 was prolonged from 2.17 h to 2.67 h after the intravenous injection of CPT-11 NPs, but its AUC had little change. After the injection of CPT-11 NPs in mice, over time, the concentrations of CPT-11-metabolized SN-38 in CPT-11 NPs were significantly higher in the whole blood, colon and lungs than those in CPT-11 solution, followed by in the spleen and liver, but those in the heart and brain had no change. However, the amount of SN-38 in the kidneys was reduced with time. CPT-11 NPs could prolong SN-38's (one of its metabolites) blood circulation time in rats and significantly increased the concentration of CPT-11-metabolized SN-38 in the whole blood, colon and lungs of mice. CPT-11 NPs made SN-38 efficiently target-bind to the colon and lungs of mice.

Objective To explore the clinical characteristics ,diagnosis, treatment and prognosis of phaeohyphomycosis. Methods Clinical data were collected, including history, physical examination, cranial and spinal imaging. Brain biopsy was performed. Data of the pathology and incubation of brain tissue were analyzed. Responsiveness to treatment was followed up. Results A previously healthy three and half years old boy was presented to our unit, with a three- month history of recurrent headache, vomiting, progressive paraplegia accompanied by urinary continence and constipation. A computed tomogram scan and magnetic resonance imaging of the brain revealed multiple lesions located in the region of the parietal - occipital lobes, periventricular area and frontal lobe, with prominent surrounding edema and irregular peripheral enhancement of the mass after the administration of contrast materials. A cerebral biopsy was performed and the pathological report was cerebral phaeohyphomycosis. The culture of the tissue and cerebrospinal fluid grew a same fungus identified as exo-phiala dermatitidis. The patient's response to therapy was poor, the parents of the boy gave up therapy, and the boy died 1 month later. Conclusions Cerebral Phaeohyphomycosis caused by Exophiala dermatitidis is rare, but the most serious form of fungus infection. Pathology and incubation of the tissue are essential for diagnosis. There is no curative therapy and the prognosis is poor.

OBJECTIVETo study the clinical features of drug-induced liver injury in children.

METHODSThe clinical data of the hospitalized children with drug-induced liver injury over 5 years were retrospectively reviewed.

RESULTSOf 641 cases of hospitalized children with liver injury, there were 64 cases (10%) of drug induced liver injury. Hepatocellular injury was the most common type of drug-induced liver injury (81%). The major drugs causing drug-induced liver injury included chemotherapy drugs, antibiotics and anti-tuberculosis drugs. Rash (16%), gastrointestinal reaction (15%), fever (14%) and liver intumescence (12%) were common clinical symptoms. A part of patients with drug-induced liver injury (11%) had no symptoms and signs.

CONCLUSIONSDrug-induced liver injury is one of the common causes of liver damage in hospitalized children. Some children with drug-induced liver injury have no symptoms and signs. Hepatocellular injury is a major type of drug-induced liver injury in children, resulting less severe liver damage.

Objective: To assess the risk of public health emergencies in Zhejiang Province, March 2021. Methods: An expert counsel was conducted to assess the risk of coronavirus disease 2019 ( COVID-19 ) , enteritis due to norovirus, chicken pox and influenza by professionals in Zhejiang CDC, based on the information from infectious disease and public health emergency surveillance in Zhejiang Province, domestic health administrative departments, World Health Organization, and European CDC. Results: In March 2021, the risk of imported COVID-19 epidemic will be high in Zhejiang Province, and the possibility of local spread could not be ruled out. The possibility of a large-scale outbreak of enteritis due to norovirus and a small-scale outbreak of chickenpox in schools and kindergartens could not be ruled out after the new term begins. An increased risk of influenza epidemic is predicted in collective units such as schools and kindergartens, yet the risk of a large-scale one will be low. Conclusion High attention should be paid to COVID-19 and enteritis due to norovirus, and general attention should be paid to chicken pox and influenza outbreak.

OBJECTIVETo observe the protective effects of total flavones of metasequosia (TFM) on cerebral ischemia-reperfusion injury in rats.

METHODThe bilateral vertebral arteries of rats were occluded under anesthesia, and 4-5 h later the carotid arteries of rats in the conscious condition were occluded for 30 min followed by reperfusion for 90 min. The effects of TFM on the contents of water, Na+, Ca2+ in cortex, malondialdehyde (MDA) content and superoxide dismutase (SOD) activity in brain hemispheres, as well as the EEG activities were observed.

RESULTAfter 30 min ischemia and 90 min reperfusion, the contents of water, Na+ , Ca2+ and MDA were increased, and the SOD activity was reduced with abnormal EEG activity and ischemic injury in the brain tissues. TFM 25-100 mg x kg(-1) ip 30 min before the carotid arteries were occluded, decreased the elevated water, Na+, Ca2+ and MDA contents, increased the SOD activity, reduced the ischemic injury of brain tissue, and promoted the recovery of EEG activities.

CONCLUSIONTFM has a protective effect on cerebral ischemia-reperfusion injury in rats.
