Objective To evaluate the effects of preoperative sleep disturbance on the consumption of propofol during the period of general anesthesia and postoperative sleep quality.Methods Sixty-five patients scheduled for elective thyroidectomy surgery under general anesthesia were enrolled in the study.According to the preoperative Pittsburgh Sleep Quality Index (PSQI) score,the patients were divided into sleep normal group (n =33) and sleep disorder group (n =32).Anesthesia was induced and maintained with propofol given by closed-loop target-controlled infusion (CLTCI).The consumption of propofol during the period of general anesthesia,postoperative sleep quality in the evening of surgery and at 24 h after operation,and the painful levels of the patients at 1 d and 2 d after operation were compared between two groups.Results The totalconsumption of propofol in sleep disorder group [(1 024.33 ±213.02)mg] was more than that in sleep normal group [(892.25 ± 242.30) mg] (P ＜ 0.05),and the dosage of unit surface area per minute of propofol in sleep disorder group [(4.94 ± 0.80) mg/(min · m2)] was also more than that in sleep normal group [(4.45 ± 0.96) mg/(min · m2)] (P ＜ 0.05).Each group suffered from bad sleep quality in the evening of operation,and got improvement one day later (P ＜ 0.05).The sleep quality in sleep disorder group was improved after general anesthesia (P ＜ 0.05).Conclusions Preoperative sleep disturbance increased the consumption of propofol in the general anesthesia.General anesthesia can improve the sleep quality of the patients who suffered from sleep disorder.

Objective To compare the accuracy of quantitative CT(QCT), perfusion scintigraphy and anatomical segmentation in predicting postoperative lung function in lung cancer patients. Methods Pulmonary functional tests, quantitative CT scan and perfusion seintigraphy in 12 cases before operation were performed. Forced vital capacity (FVC), the first second forced expiratory volume (FEV1.0) and diffusing capacity of carbon monoxide (DLco) were obtained from preoperative pulmonary functional tests. According to the corresponding formula for QCT, perfusion sintigraphy and anatomical segmentation method, the values of FVC, FEV1.0 and DLco were predicted. The correlation between the predicted values and postoperative values of FVC, FEV1.0 and DLco were assessed. The paired-t test,Pearson correlation test and Bland-Altman analysis were used for the statistics. Results The predicted values of QCT, perfusion sintigraphy and anatomical segmentation method were: FVC [(3.05±0.82), (2.98±0.75) and (2.98±0.86) L,respectively] , FEV1.0[(2.20±0.81), (2.17±0.78) and (2.16±0.84) L, respectively], DLco (FVC: r=0.87, 0.80 and 0.86; FEV1.0:r =0.93, 0.91 and 0.93; DLco:r =0.93, 0.95 and 0.93,respectively,P < 0.01). Conclusion QCT, perfusion sintigraphy and anatomical segmentation method can be used in predicting postoperative lung function. The predicted values are in concordance with the postoperative ones.

Objective To analyze the indications of clip deployment and influencing factors for clip dislocation immediately after stereotactic vacuum-assisted breast biopsy. Methods One hundred and fourteen microcalcifications in 108 women aged 35 to 85 years old (median 63 years) underwent 11-gauge stereotactic vacuum-assisted breast biopsy. Every lesion was marked on biopsy site with Gel Mark Ultra clips (n = 82) or MicroMark Ⅱ clips ( n = 32) after biopsy. All microcalcifications were classified 3 mono-focal groups: < 10 mm, 10--20 mm, > 20 mm and one muhi-focal group according to its diameter and distribution. The distances between clips and biopsy sites were directly measured on post-biopsy craniocaudal and mediolateral mammograms. The distance was recorded as < 10 mm, 10--20 mm and >20 mm. Results 88% (22/25) of mono-focal microcalcifications smaller than 10 mm and 70% (14/20) of mono-focal microcalcifications measured 10--20 mm were completely removed on mammograms, whereas none of mono-focal microcalcifications larger than 20 mm (n = 17) was completely removed. 65.8% (75/114) of the clips were accurately located. Thirty-nine clips were dislocated on at least one projection with 87.2% (34/39) of the clips dislocated only along the needle track, which is called "accordion effect". Hematoma was found in 4 patients, and the clip was accurately localized only in one case with hematoma, Conclusions Clips should be deployed as a standard procedure for mono-focal microcalcifications smaller than 20 mm and all multi-focal mierocalcifications. The major reasons for clip dislocation immediately after biopsy are the accordion effect and hematoma.

In order to study the factors influencing quantitative measurement of CT lung densitometry, 54 healthy adults underwent lung spiral scans at 50 % vital capacity (VC). Among the 54 cases, 40 received HRCT scan at carina and 5 cm away from carina (± 5 cm) at 10 % VC and 90 % VC, 23 lung HRCT at those three sections at 50 % VC. Using automatic evaluation software-Pulmo, mean lung density (ME) and pixel index (PI) at each section were evaluated. It was found that the depth of respiration affected ME and PI markedly. The ME changed 125.91 Hu between 10 % VC to 90 % VC. The ME and PI were also influenced by collimation, age and sex. It was concluded that it was very important to control the depth of respiratory. The normal CT attenuation values for the lung should be established.

Objective To explore the relationship between platelet to lymphocyte ratio (PLR) and microangiopathyin type 2 diabetes mellitus. Methods In this case-control study, the clinical data on 428 adult patients with type 2 diabetic microangiopathy in our hospital from January 2009 to December 2015 were retrospectively analyzed. PLR, age, sex, fasting blood glucose, glycosylated hemoglobin, total cholesterol and triglyceride were tested to investigate their relationship with type 2 diabetic microangiopathy. Results Logistic regression analysis showed that PLR was a risk factor of type 2 diabetic microangiopathy (OR = 3.162, 95%CI:1.556 ~ 7.421, P < 0.05). Conclusions Greater PLR is closely related to type 2 diabetic microangiopathy, and we should pay attention to type 2 diabetic microangiopathy with a greater PLR in clinical practice.

To explore the clinical manifestations, diagnosis and treatment of pulmonary thromboembolism associated with protein C (PC)/protein S (PS) deifciency. Two male patients 29 and 26 years old diagnosed with PC deifciency and/or PS deifciency were retrospectively analyzed and related literatures were reviewed. The most common symptoms were pain in the lower limbs with chest pain or decreased vision. Color dopper lfow imaging (CDFI) showed lower deep venous phlebothrombosis. Multislice CT angiography (CTA) revealed pulmonary embolism. The level of serum homocysteine (HCY) increased and the level of plasma PC/PS content decreased to PC 57.4%, and PS 28.9%in patient 1, while PS 33.4%in patient 2. Poor routine anticoagulant response was observed. After the diagnosis of PC/PS deficiency, vitiamin B6 and B12 anticoagulant therapy was added, and the symptoms in the patients improved significantly. Congenital thrombophilia should be taken into consideration for young patients with lower deep venous thrombosis and pulmonary embolism which occur recurrently without obvious predisposing causes before 40. Plasma PC/PS concentrations or activity help a lot in the diagnosis and treatment.
