Objective:To explore the risk factors of deep vein thrombosis (DVT) in hospitalized rehabilitation patients.Method:Clinical data of 1 130 patients, 737 males and 393 females with the mean age of 63.0 (54.0, 73.0) years, admitted in the Department of Rehabilitation Medicine of the Second Hospital of Jiaxing from August 2021 to September 2022 were retrospectively analyzed. Patient underwent vascular color ultrasound examination, DVT was detected in 194 cases (DVT group) and not detected in 936 cases (control group). The general clinical data, venous thromboembolism (VTE) risk stratification and traditional VTE risk factors of patients were documented. The risk factors of DVT formation were analyzed with multivariate logistic regression.Results:Compared with the control group, the DVT group had a higher proportion of patients with older age, longer length of hospital stay, and positive D-dimer (all P<0.001). The proportion of patients with high risk of VTE in the DVT group was 49.5% (96/194), which was higher than that in the control group (27.0% (253/936), P<0.01). The proportion of patients with age≥70 years, previous venous thromboembolism, and history of recent (≤1 month) trauma or surgery in the DVT group was significantly higher than that in the control group (all P<0.001). The proportion of patients with primary diagnoses of quadriplegia, hemiplegia or other motor disorders in the DVT group was significantly higher than that in the control group ( P<0.01). Multivariate logistic regression analysis showed that old age ( OR=1.014, 95% CI: 1.012-1.016), length of hospital stay ( OR=1.001, 95% CI: 1.001-1.002), positive D-dimer ( OR=2.508, 95% CI: 2.368-2.655), high risk of VTE ( OR=1.178, 95% CI: 1.10-1.250), quadriplegia ( OR=2.776, 95% CI: 2.552-3.021), hemiplegia ( OR=3.232, 95% CI: 2.996-3.488), motor disorders ( OR=2.308, 95% CI: 2.110-2.525), paraplegia ( OR=1.878, 95% CI: 1.622-2.175), previous venous thromboembolism ( OR=1.385, 95% CI: 1.314-1.460), history of recent (≤1 month) trauma or surgery ( OR=1.987, 95% CI: 1.886-2.093) (all P<0.001) were independent risk factors for DVT in rehabilitation inpatients. Conclusion:Age, length of hospital stay, primary diagnosis of quadriplegia, hemiplegia, paraplegia or other motor disorders, positive D-dimer, high risk of VTE, previous venous thromboembolism, and history of recent trauma or surgery are independent risk factors for DVT in rehabilitation specialty inpatients.

Objective To evaluate the levels of oxidative stress in patients undergoing long-term and repetitive exposure to hyperbaric oxygen (HBO) treatment. Methods 16 healthy volunteers and 58 patients with sub-acute sudden hearing loss (SHL) exposed to HBO were included in the study. Oxidative stress indices (malondialdehyde, MDA, advanced oxidation protein products, AOPP; superoxide dismutase, SOD) were measured in peripheral blood samples collected at the 5th,10th, 20th and 30th HBO treatments sessions (PO2 0.18 MPa, 1 session per day and 5 sessions per week) and under normal ambient pressure respectively. Results After 5th,10th, 20th and 30th sessions of HBOT, no relevant differences in these three indices were detected compared to pre-HBO exposure, between healthy volunteers (P > 0.05). Conclusions The long-term repetitive HBO treatment for 0.18 MPa of PO2 and 30 sessions could not affect in particular the response of the oxidative stress in healthy persons and patients with sub-acute SHL. The influence on three indices of patients with abnormal situation of oxidative stress undergoing lower pressure of HBO (0.18 MPa) is under investigation.

Objective To observe the oxygen-breathing efficacy by using different breathing apparatuses during normal pressure oxygen-breathing treatment and HBO treatment (HBOT) in the multi-seats chamber.Methods Changes in curve of transcutaneous oxygen partial pressure (TcPO2) for the 30 subjects,who had oxygen-breathing both at normal pressure and at a pressure of 0.22 MPa by using different types of apparatus were monitored continuously.Results (1) The curves of normal TcPO2 both at normal pressure and at 0.22 MPa were displayed in three stages:the compressing stage (1-5min after oxygen-breathing started until peak was reached) ; the plateau peak stage (the time when the peak arrived till decompression started) ; the decompression stage (the time when decompression was started till 20 minutes after oxygen-breathing was terminated).The elevation and declining of the curve synchronized with oxygen-breathing.(2) Oxygenbreathing by using different types of breathing apparatus tended to induce changes in the TcPO2 curves.(3)Before entrance into the chamber,instruction on the correct wearing of oxygen-breathing apparatus was an important measure for maintenance of the TcPO2 curves.Conclusions The TcPO2 curves synchronized with oxygen-breathing and was obviously affected by different types of apparatus.The TcPO2 curve could be used as an objective indicator for dynamic and real-time monitoring of oxygen-breathing efficacy in the multi-seats chamber.

Serum Ca, P, AKP, plasma iPTH, cAMP, urinary Hyp and BMC were measured in 31 cases of Graves' disease. The results showed that about 66.67% of the patients (including 21 controlled and 10 uncontrolled cases) had a decreased BMC, while serum Ca, P, plasma iPTH, cAMP were within the normal range. The data also showed that about 54.6% of the patients had increased serum AKP, but it would not exceed 25 U if no hepatic disease existed. There were positive correlations between serum T, and urinary Hyp, and between urinary Hyp and serum AKP, but a negative correlation between urinary Hyp and BMC. It was suggested that serum AKP and urinary Hyp could be considered as the indices of negative balance of bone metabolism in Graves' disease, and probably it was induced by excessive thyroid hormone directly.
