ABSTRACT
In order to improve the level of epidemic prevention and control, and strengthen the observation and monitoring of potential patients with viral pneumonia in isolated state, a medical intelligent monitoring collar based on DA14699 Bluetooth low-power chip was proposed. DA14699 chip is used as the main controller in the design scheme, and the temperature, cough and location information of potential patients are recorded and analyzed by its high-efficiency wireless multi-core processing ability. The LIS3DH three-axis acceleration sensor is used to judge the cough symptoms. The MLX90640 infrared sensor is used to continuously measure the body temperature. The L218 four frequency GSM / GPRS positioning module is used to complete the rapid and accurate positioning of personnel, so as to realize the comprehensive supervision of the implementation of home isolation measures. DA14699 chip supports Bluetooth BLE5.1 protocol. Epidemic prevention personnel can transmit and read the data recorded in the smart collar from a long distance, and display it directly on the intelligent Bluetooth handheld terminal, effectively avoid the risk of infection caused by close contact. Through the actual test, the monitoring function of the key parameters of the collar is reliable and has high application value.

Objective To explore an ideal surgical method for mid-low face lifting.Methods In this procedure,the first surgical step was subcutaneous undermining that was performed through the incision along temporal hairline,anteriorear,and mastoideae.It extended distally beyond the furthest skin fold and along the mandibular border or the midline of the neck if nacessary.Then three layers suspension were performed,which included three procedures:first,SMAS was purse string sutured in certain direction;secondly,the malar fat pad was suspended to tow directions backward and upward and anchored in the periosteum of zygoma and SMAS too;lastly,through traction suture of reducing tension step-by-step,lots of the tension was relieved from the incision;at the same time,new retaining ligaments between flap and SMAS were reestablished.And redundant skin was removed in incision at the end of the procedure.Results A total of 22 cases received this operation.16 cases were followed up from 3 months to 24 months after operation.The results of operation were divided into three degrees:excellent,acceptable and poor;and those were evaluated by patients themselves.14 cases obtained excellent result (87.5 ％),2 cases regarded that their results were acceptable (12.5 ％).The total satisfactory rate was 100 ％.None serious complication occurred in those eases except some slight complications,such as local edema,skin numbness and small hematoma which relieved in 3 to 6 months after operation.Scar was inconspicuous.Conclusions This technique can correct the posies of lower tow-third face better,especially for mitigating the nasolabial fold and enhancing the elastic of face skin.Simultaneously,it is an effective,safe and simple technique.
ABSTRACT
To enhance the scientific and fair evaluation about proprietary Chinese medicines containing toxic herbs during the switch process of non-prescription drugs, and to ensure those medicines to be used safely by the public in their self-medication. Combined with current research status of toxic herbs, the experience and knowledge accumulated in the practical work of selection and switch of OTC Chinese medicines for years, thinking about the feasible standards about evaluation and management of proprietary Chinese medicines containing toxic herbs at this stage. Initially established ideas and methods about evaluation of proprietary Chinese medicines containing toxic herbs during the switch process of non-prescription drugs. Basically solved the main problem currently faced by toxic herbs during the OTC switch process of proprietary Chinese medicines, effectively promoted the work on OTC switch, and had the important significance in making consumers use non-prescription drugs conveniently and safely.

This study examined the adipocytokine-vascular interactions and link between epicardial adipose tissue and coronary artery atherosclerosis. Thirty-four patients undergoing open heart surgery were chosen randomly, and divided into group I (non-coronary artery disease group) and group II (coronary artery disease group). Blood samples were taken through peripheral vein prior to surgery. Plasma levels of a panel of proteins (adiponectin, IL-10, TNF-α) were detected by using ELISA. Epicardial adipose tissue was taken near the proximal tract of the right coronary artery and subcutaneous adipose was taken from the leg before cardiopulmonary bypassing, adiponectin and CD68 + were detected by using RT-PCR and immunohistochemistry. Our results showed that plasma adiponectin level was significantly lower in the group II as compared with group I (P<0.05). There were no differences in plasma concentration (IL-10, TNF-α, tatal-chol, HDL-chol, LDL-chol) between group I and group II. The number of CD68+ cells in epicardial adipose tissue of group II was significantly higher than that in subcutaneous adipose tissue. Adiponectin mRNA expression was 6 fold higher in subcutaneous adipose tissue than in epicardial adipose tissue of group II (P<0.01). Furthermore, the level of adiponectin mRNA in the epicardial adipose tissue in group II was also significantly lower than in group I (P<0.05). We are led to conclude that inflammation that occurs locally in epicardial adipose tissue of CAD contributes to the pathogenesis of coronary artery disease.
ABSTRACT
Objective To explore an ideal surgical treatment for cervical sear eontraeture. Methods From January, 2005 to December, 2008, 11 eases of cervical sear contraeture (Ⅱ-Ⅲ) were treated with the expanded flaps based on the cervical cutaneous branch of transverse cervical artery. At the first step, one or two soft tissue expanders were implanted beneath the skin at the clavicular-pectoral region. At the second step, after fully expanding, an expanded clavicular-pectoral flap that based on the cervical cutaneous branch of transverse cervical artery was designed and raised completely according to cervical cutaneous defect. And then, the flap was transferred to reconstruct the defect in cervix. The donor area was closed directly or covered with graft. Results The 11 cases were performed with unilateral flaps based on the cervical cutaneous branch of transverse cervical artery. No necrosis occurred. And the cervical contour and function have been mended. All of them had been followed up for 6-18 months with satisfactory results. Conclusions This procedure can be very useful for the plastic and reconstruction surgeons who are confronted with a difficult case of cervical scar contracture. By this means, a lot of materials of reparation with similar color, and texture can be obtained. And this method is simple, safe, and effective.
