Objective To evaluate the clinical effectiveness of early interfering of yellow-water on Deep Venous Thrombosis (DVT) in lower extremities of hip fracture patients after operation. Methods 60 patients with hip fracture were recruited into a control group and a treatment group randomly. The control group was treated with low molecular heparin,while the treatment group was treated additionally with yellow-water on that basis. The status of pain, swelling levels, vascular color doppler ultrasound and safety of medication were reviewed after two weeks. Results There was 23.3% cure rate and 60.0% significant improvement rate in the treatment group, and 13.3% cure rate and 40.0% significant improvement rate in the treatment group. The therapeutic effect in the treatment group was better than the control group, with significant difference (P＜0.05 ) . Conclusion Yellow-water was effective in early interfering in DVT in lower extremity due to its quickness in eliminating swelling and alleviating pains with no stimulus feeling.

Objective To explore the clinical features and causes of misdiagnosis of the patients with acquired deficiency of vitamin K-dependent coagulation factors (ADVKDCF). Methods Retrospective analysis was performed with the data from 62 patients with ADVKDCF for etiological factors, clinical manifestations,laboratory examinations, diagnosis and treatments. Results Among the 62 patients, 51 patients were with unknown causes( subgroup A) and 11 were with clear histories of anticoagulant rodenticide poisoning( subgroup B). The presentations of hemorrhage of the patients varied with hematuria as the most common first symptom,followed by skin, mucosa, muscle, internal organs bleeding (28/62). The most common hemorrhage symptom is hematuria. 35 of the 62 patients had hemoglobin(Hb) levels less than 100 g/L due to blood loss( the lowest level was 32 g/L). Thirty-eight patients were misdiagnosed at the first visit and the median time from hemorrhage manifestation to definite diagnosis was 8 days (range,2 to 192 days). ADVKDCF was mostly misdiagnosed as the urinary system diseases (23/38), followed by hemophilia (8/38). Laboratory examinations showed normal platelet count , throm bin time (TT) and normal fibrinogen(Fg) concentration, but prolonged plasma prothrombin time (PT), activated partial prothrombin time (APTT) and international normalized ration (INR). All of patients received high dose vitamin K ( intravenous vitamin K1 with a initial dose of 20 to 240 mg/d and then oral vitamin K4 maintenance) . The bleeding symptoms disappeared 1 day after treatment and the Hb levels increased dramatically. There were significant differences in PT, APTT and INR of the patients before and after treatment( P ＜0. 01 ). Followed by a median follow - up of 8 months , no patient had severe adverse effects or recurrence. Conclusion The hemorrhage presentations of the patients with ADVKDCF are various. The most common hemorrhage symptom is hematuria. The misdiagnosis rate of ADVKDCF is high with urinary systems disorders as the most common misdiagnosis. Sequential treatment with vitamin K is an effective and safe method to prevent recurrence. Early detection of coagulation function is helpful to reduce misdiagnosis possibility.

Objective:To monitor and evaluate in vivo dose changes of intensity-modulated radiotherapy (IMRT) in patients with cervical cancer in a real-time manner. Methods:Twelve patients with cervical cancer admitted to our hospital were enrolled in this study. The in vivo doses were monitored by PerFRACTION?. Electronic portal imaging device (EPID) were collected in each treatment fraction for two-dimensional in vivo dose verification[γ index and dose difference (DD) index]. Log files were recorded for three-dimensional in vivo dose verification (γ index). The correlation between in vivo dose and treatment duration was analyzed by Pearson correlation analysis. Results:A total of 206 sets of EPID images and corresponding Log files were collected. The three-dimensional in vivo dose verification γ 1%/1mm of all patients was not correlated with treatment fraction ( P>0.05). Among them, the absolute difference of γ 1%/1mm of 94.66% fractions was< 1%. The mean DD 3% of two-dimensional in vivo dose verification of all patients was negatively correlated with treatment fraction ( P<0.05). Among which, the average γ 3%/3mm of 9 patients was>89% in the treatment fractions, and the average γ 3%/3mm of 98.57% fractions of these 9 patients was>93%. The other 3 patients had an average γ 3%/3mm ranged from 38% to 100%. CBCT images showed that the bladder volume of these 3 patients was significantly decreased with the relative changes by 82.08%, 84.41% and 73.59%, respectively, and the target area was retracted significantly with the relative changes by 38.12%, 59.79% and 24.46%, respectively. Conclusion:Combined with γ index and DD index, PerFRACTION? can monitor the mechanical stability of accelerator and MU delivery accuracy during treatment fractions, and monitor the changes of in vivo dose in patients with cervical cancer, which can improve the safety and quality assurance of IMRT for cervical cancer patients and provide guidance for patients with adaptive radiotherapy.
