Objective Based on the PSQ-18 scale, to evaluate the effects of disease classification early warning system (DCEWS) on operation quality of health examination center (HEC). Methods By means of the comparable and retrospective cohort study methods, using “PSQ-18” of American Rand Corporation as a tool, taking the date when HEC implemented DCEWS as node, and adopting statistic software for random sampling, it was divided into two groups: the traditional group (before implementing DCEWS, n=475) and the early warning group (after implementing DCEWS, n=473). The PSQ-18 scale scores of both groups were analyzed so as to assess the effects of DCEWS on HEC. Results Such factors as sex, age, education level and family average monthly income had certain effects on the score of PSQ-18, but there was no significant difference between the two groups (Pgt;0.05); in the following 4 dimensions as the ways of interpersonal communication, degree of doctor-patient communication, convenience degree and the overall satisfaction of patients, the PSQ-18 scores of the traditional group and the early warning group were 4.0±0.92/4.2±0.97, 3.8±0.94/4.0±0.96, 4.4±0.60/4.6±0.6, 4.2±0.87/4.4±0.94, respectively, with significant differences (all Plt;0.05). Conclusion The implementation of “Disease classification early waning system” can significantly increase the “patient satisfaction” of health examinees, and can significantly improve the operation quality of health examination center.
ObjectiveTo evaluate the effectivness of using high porous polyethylene lower eyelid spacers (Medpor LES) combined with the lateral tarsal-strip procedure for reconstruction of the eyelid closure function in paralytic lagophthalmus after facial palsy. MethodsBetween March 2008 and December 2012, 32 patients (32 eyelids) with hypophasis in facial palsy which all sorts of causes lead to were treated with Medpor LES combined with the lateral tarsal-strip procedure. Of 32 cases, 20 were male and 12 were female, aged from 20 to 72 years (mean, 46.8 years). The left eye was involved in 18 cases and the right eye in 14 cases with a disease duration of 1.5 months to 2 years (mean, 4.4 months). All the patients were shown as lower eyelid ectropion, lower eyelid retraction, exposure keratitis, and corneal ulcer, but no obvious upper eyelid retraction was observed. ResultsPrimary healing of incision was obtained in all patients. The edema time of the eyelid was from 5 days to 3 weeks (mean, 2 weeks). Conjunctival edema appeared in 4 cases after 2 weeks of operation, which was cured after expectant treatment. The patients were followed up 5-8 months (mean, 6 months). At 1 week, 3 and 6 months after operation, the height of palpebral fissure was reduced, and the degree of lagophthalmus and low eyelid retraction were significantly corrected (P<0.05), but no significant difference among different time points after operation (P>0.05). Outer canthus displacement occurred in 3 cases at 1 month postoperatively, and was cured after the lateral tarsal strip procedure. No lower eyelid ectropion, corneal exposure, or Medpor LES displacement and exposure occurred during follow-up. ConclusionMedpor LES combined with the lateral tarsal-strip procedure has good effectiveness for reconstruction of eyelid closure function in most cases of paralytic lagophthalmus after facial palsy.
Cardiotocography (CTG) is a commonly used technique of electronic fetal monitoring (EFM) for evaluating fetal well-being, which has the disadvantage of lower diagnostic rate caused by subjective factors. To reduce the rate of misdiagnosis and assist obstetricians in making accurate medical decisions, this paper proposed an intelligent assessment approach for analyzing fetal state based on fetal heart rate (FHR) signals. First, the FHR signals from the public database of the Czech Technical University-University Hospital in Brno (CTU-UHB) was preprocessed, and the comprehensive features were extracted. Then the optimal feature subset based on the k-nearest neighbor (KNN) genetic algorithm (GA) was selected. At last the classification using least square support vector machine (LS-SVM) was executed. The experimental results showed that the classification of fetal state achieved better performance using the proposed method in this paper: the accuracy is 91%, sensitivity is 89%, specificity is 94%, quality index is 92%, and area under the receiver operating characteristic curve is 92%, which can assist clinicians in assessing fetal state effectively.
With the development and improved availability of low-dose computed tomography (LDCT), an increasing number of patients are clinically diagnosed with lung cancer manifesting as ground-glass nodules. Although radical surgery is currently the mainstay of treatment for patients with early-stage lung cancer, traditional anatomic lobectomy and mediastinal lymph node dissection (MLND) are not ideal for every patient. Clinically, it is critical to adopt an appropriate approach to pulmonary lobectomy, determine whether it is necessary to perform MLND, establish standard criteria to define the scope of lymph node dissection, and optimize the decision-making process. Thereby avoiding over- and under-treatment of lung cancer with surgical intervention and achieving optimal results from clinical diagnosis and treatment are important issues before us.
Along with the popularity of low-dose computed tomography lung cancer screening, an increasing number of lung ground-glass opacity (GGO) lesions are detected. The pathology of GGO could be benign, but persistent GGO indicates early-stage lung cancer. Distinct from traditional lung cancer, GGO-featured lung cancer is more common in the young, nonsmokers and females. GGO-featured lung cancer represents an indolent type of malignancy with a long time to intervene. However, there is still no consensus on the screening, pathology, surgical procedure, and postoperative surveillance of GGO-featured lung cancer. Therefore, we proposed a personalized treatment strategy for GGO-featured lung cancer. The screening for GGO-featured lung cancer should be conducted at young age and low frequency. Adenocarcinoma in situ, minimally invasive adenocarcinoma, lepidic, and non-lepidic growth patterns could present as GGO. The following issues should be taken into consideration while determining the treatment of GGO-featured lung cancer: avoiding treating benign disease as malignancies, avoiding treating early-stage disease as advanced-stage disease, avoiding treating indolent malignancy as aggressive malignancy, and choosing appropriate timing to receive surgery without affecting life tracks and career developments. Bronchoscope and bone scan are not necessary for preoperative examinations of GGO-featured lung adenocarcinoma. For selected patients, sublobar resection without mediastinal lymph node dissection might be sufficient. Intraoperative frozen section is an effective method to guide resection strategy. Given the excellent survival of GGO-featured lung cancer, a less intensive postoperative surveillance strategy may be sufficient.
Along with the popularity of low-dose computed tomography lung cancer screening, an increasing number of early-stage lung cancers are detected. Radical lobectomy with systematic nodal dissection (SND) remains the standard-of-care for operable lung cancer patients. However, whether SND should be performed on non-metastatic lymph nodes remains controversy. Unnecessary lymph node dissection can increase the difficulty of surgery while also causing additional surgical damage. In addition, non-metastatic lymph nodes have been recently reported to play a key role in immunotherapy. How to reduce the surgical damage of mediastinal lymph node dissection for early-stage lung cancer patients is pivotal for modern concept of "minimally invasive surgery for lung cancer 3.0". The selective mediastinal lymph node dissection strategy aims to dissect lymph nodes with tumor metastasis while preserving normal mediastinal lymph nodes. Previous studies have shown that combination of specific tumor segment site, radiology and intraoperative frozen pathology characteristics can accurately predict the pattern of mediastinal lymph node metastasis. The personalized selective mediastinal lymph node dissection strategy formed from this has been successfully validated in a recent prospective clinical trial, providing an important basis for early-stage lung cancer patients to receive more personalized selective lymph node dissection with "precision surgery" strategies.
Objective To evaluate the current status of classification and repair methods for dural injury caused by spinal surgery or trauma, providing new strategies and ideas for the clinical repair of dural injury and the development of related materials. MethodsThe literature related to dural injury both at home and abroad in recent years was thoroughly reviewed and analyzed in order to draw meaningful conclusions. ResultsThere have been numerous retrospective studies on dural injury, but there is a scarcity of prospective and multi-center studies, resulting in a low level of evidence-based research. The incidence and risk factors of dural injury have primarily been studied in relation to common degenerative spinal diseases of the cervical and lumbar spine, with insufficient research on thoracic spine-related diseases. Currently, a universally recognized method for grading and classifying dural injury has not been established, which hampers the development of clinical guidelines for their repair. Furthermore, although there are repair materials and surgical strategies available to address clinical issues such as suture leakage and surgical repair of dural injury in complex locations, there is a lack of comprehensive clinical research and evidence-based data to validate their scientificity and reliability. ConclusionRegardless of the classification of dural injury, suture remains the most important repair method. It is important to further develop new patches or sealants that can meet clinical needs and reduce the difficulty of repair.
