The cognitive impairment of type 2 diabetes patients caused by long-term metabolic disorders has been the current focus of attention. In order to find the related electroencephalogram (EEG) characteristics to the mild cognitive impairment (MCI) of diabetes patients, this study analyses the EEG synchronization with the method of multichannel synchronization analysis--S estimator based on phase synchronization. The results showed that the S estimator values in each frequency band of diabetes patients with MCI were almost lower than that of control group. Especially, the S estimator values decreased significantly in the delta and alpha band, which indicated the EEG synchronization decrease. The MoCA scores and S value had a significant positive correlation in alpha band.

Objective: To analyze the current situation and effect of vertical integrated of rural health services in Dafeng County. Method: Policy documents and data are collected and interviews are implemented for studying the integrated situation. Results: The vertical integration in Dafeng County is virtual joint form with forming 6 city-level medical volunteer service teams and 52 health management teams. With the imple-mentation of fully integrated management, signing service with rural doctor mode is carried out, which pro-mote the establishment of rural unified service standards and regulations. Using health card of residents which promote the regional shared of treatment information. Conclusions: Vertically integrated mode had connection in health management teams, supported by fully integration, developed by signing service with rural doctor and carried by residents’ health card, which could provide reference for implementing vertical integration of rural health service. But strategies needed to be strengthened in improving health services’ ability of township hospitals, clarifying interest relationship as well as integrating health service regulations and strengthen the health information system for sharing and docking.

Aiming at the problem that it is difficult to accurately recognize the position and the figure of P wave in the ECGs easily influenced by the diversified interference,a P wave detection algorithm based on approximating functions in the optimum region is proposed in this paper. In the algorithm we use a conic to approach the P wave by means of the least square method in every region, which is shifted in local range. Then we find the optimum approach region of P wave by comparing the approximating error. Finally, we attain the characteristic points of P wave by using the approximating functions to approach P wave in the optimum region. The performance of the algorithm tested using the records of the MIT-BIH database is effective and accurate.

Epilepsy is a recurrent, transient seizure disorder of the nervous system that affects the intellectual development, life and work, and psychological health of patients. People with epilepsy worldwide experience great suffering. Stressful stimuli such as infection, mental stress, and sleep deprivation are important triggers of epilepsy, and chronic stressful stimuli can lead to frequent seizures and comorbidities. The hypothalamic-pituitary-adrenal (HPA) axis is the most important system involved in the body’s stress response, and dysfunction thereof is thought to be associated with core epilepsy symptoms and related psychopathology. This article explores the intrinsic relationships of corticotropin-releasing hormone, adrenocorticotropic hormone, and glucocorticoids with epilepsy in order to reveal the role of the HPA axis in the pathogenesis of epilepsy. We hope that this information will yield future possible directions and ideas for fully understanding the pathogenesis of epilepsy and developing antiepileptic drugs.

As the main stabilizing structure of the medial ankle joint, deltoid ligament plays a role in counteracting excessive eversion of the hindfoot and external rotation of the talus during ankle movement so as to maintain the biomechanical stability of ankle joint. Although the incidence of deltoid ligament injury is low, improper diagnosis and treatment can affect the path of talus motion and eventually lead to chronic medial instability or traumatic arthritis of the ankle joint, seriously affecting the normal life and motor function of the patients. The diagnosis of deltoid ligament injury needs to be based on the characteristics of the injury, physical examination and imaging, among which X-ray, MRI and ultrasonography are most frequently used. There are various methods to treat deltoid ligament injury according to the type of injury, and thus the choice of treatment has been a hot topic in the field of foot and ankle surgery. The choice of non-surgical or surgical treatment for acute deltoid ligament injury remains controversial. For the treatment of chronic deltoid ligament injury, there is no consensus on direct repair or deltoid ligament reconstruction. In addition, the choice of autologous or allograft tendon or wire anchors for deltoid ligament reconstruction is also disputed. The rehabilitation of deltoid ligament injury is crucial to the early restoration of motor function of the ankle joint, but the related guidelines or consensus are scarce. In order to fully understand the characteristics of deltoid ligament injury, make accurate diagnosis and formulate reasonable treatment and rehabilitation programs, the authors review the research progress in deltoid ligament injury from aspects of anatomical characteristics, biomechanical mechanism of injury, diagnosis, treatment and postoperative functional rehabilitation, hoping to provide a reference for the clinical diagnosis and treatment of deltoid ligament injury.

BACKGROUND:
The previous study has indicated that lung cancer has a high incidence and mortality in China, and has caused a large economic burden. The purpose of this study was to analyze the incidence and economic burden of lung cancer by analyzing the information on the home page of discharge history of lung cancer patients in Hebei Tumor Hospital, and to provide scientific basis for the prevention and treatment of lung cancer.
METHODS:
The information of all of the discharges, new cases, surgical patients, age, gender, length of stay and hospitalization cost of lung cancer patients in Hebei Tumor Hospital from January 2012 to December 2019 were retrieved based on the medical record management system, and the incidence trend, gender and age distribution as well as the economic burden of the disease were statistically described.
RESULTS:
The number of new cases of lung cancer increased year by year, from 2,235 cases in 2012 to 5,012 cases in 2019. The number of males always outnumbered females, but the gender ratio decreased year by year, from 2.25 in 2012 to 1.56 in 2019. Among new cases of lung cancer, the proportion of surgical treatment increased year by year, from 28.14% in 2012 to 44.83% in 2019. Except for 2012, the proportion of surgical operations in female patients was higher than that in male patients from 2013 to 2019. The proportion of surgical operations in male and female patients was 23.52% and 28.07% in 2013, and 36.14% and 58.37% in 2019, respectively. The median age at the onset of lung cancer has increased year by year, from 61 years old in 2012 to 63 years old in 2019. The median age of onset in all lung cancer patients was higher in males than in females. The number of new lung cancer patients and surgical patients both showed an increasing trend with the increase of age, and both reached the maximum value in the age group of 60-69 years old. With the increase of age, the number of patients gradually decreased. The median length of hospital stay for all discharged lung cancer patients or surgical patients decreased year by year, from 10 d and 19 d in 2012 to 8 d and 17 d in 2019, respectively, while the median hospitalization cost increased year by year. It increased from 10,611.46 yuan and 38,750.13 yuan in 2012 to 17,187.15 yuan and 84,030.16 yuan in 2019, respectively.
CONCLUSIONS
Lung cancer is still one of the main cancers endangering the health of Chinese residents. The incidence of lung cancer is increasing year by year, and the distribution of gender and age has certain characteristics. In order to reduce the number of cases and the economic burden, effective prevention and control measures should be formulated and medical reform should be strengthened.
