Objective To investigate the effect of erector spinae plane block on postoperative delirium and cognitive function in elderly patients with lung cancer undergoing thoracoscopic radical surgery.Methods A total of 90 elderly patients with lung cancer underwent thoracoscopic radical surgery were selected and randomly divided into the control group and the observation group,with 45 cases in each group.The patients in the control group were given general anesthesia,while the patients in the observation group were given erector spinae plane block before general anesthesia.The vital signs at different time points,opioid dosage,number of analgesic pump compressions,incision pain visual analogue scale(VAS)score,cognitive function and postoperative delirium of patients between the two groups were compared.Results At the end of anesthesia,the mean arterial pressure(MAP)and heart rate of patients in the observation group were significantly lower than those in the control group(P<0.05).The dosage of remifentanil during operation,sufentanil during perioperative period and number of analgesia pumps compressions of patients in the observation group were significantly less than those in the control group(P<0.05).The incision pain VAS scores 6 hours,12 hours,24 hours and 48 hours after surgery of patients in the observation group were significantly lower than those in the control group(P<0.05).The scores of cognitive function 6 hours and 24 hours after surgery of patients in the observation group were significantly higher than those in the control group(P<0.05);and the incidence of delirium 6 hours and 24 hours after surgery in the control group was significantly higher than those in the observation group(P<0.05).Conclusion Erector spinae plane block can significantly relieve the perioperative pain of elderly patients with lung cancer undergoing thoracoscopic radical surgery,reduce the dosage of opioids and the incidence of postoperative delirium,improve the postoperative cognitive function of patients,which provides a new idea for reducing the incidence of postoperative mental diseases.

OBJECTIVES: To investigate the clinical treatment outcomes and the changes of the outcomes over time in extremely preterm twins in Guangdong Province, China. METHODS: A retrospective analysis was performed for 269 pairs of extremely preterm twins with a gestational age of <28 weeks who were admitted to the department of neonatology in 26 grade A tertiary hospitals in Guangdong Province from January 2008 to December 2017. According to the admission time, they were divided into two groups: 2008-2012 and 2013-2017. Besides, each pair of twins was divided into the heavier infant and the lighter infant subgroups according to birth weight. The perinatal data of mothers and hospitalization data of neonates were collected. The survival rate of twins and the incidence rate of complications were compared between the 2008-2012 and 2013-2017 groups. RESULTS: Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of severe asphyxia and smaller head circumference at birth (P<0.05). The mortality rates of both of the twins, the heavier infant of the twins, and the lighter infant of the twins were lower in the 2013-2017 group compared with the 2008-2012 group (P<0.05). Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of pulmonary hemorrhage, patent ductus arteriosus (PDA), periventricular-intraventricular hemorrhage (P-IVH), and neonatal respiratory distress syndrome (NRDS) and a higher incidence rate of bronchopulmonary dysplasia (P<0.05). CONCLUSIONS There is a significant increase in the survival rate over time in extremely preterm twins with a gestational age of <28 weeks in the 26 grade A tertiary hospitals in Guangdong Province. The incidences of severe asphyxia, pulmonary hemorrhage, PDA, P-IVH, and NRDS decrease in both the heavier and lighter infants of the twins, but the incidence of bronchopulmonary dysplasia increases. With the improvement of diagnosis and treatment, the multidisciplinary collaboration between different fields of fetal medicine including prenatal diagnosis, obstetrics, and neonatology is needed in the future to jointly develop management strategies for twin pregnancy.

This study was designed to investigate the flavor and taste change rules of Sophora Flavescentis Radix processed using the ancient classical method documented in Master Lei's Discourse on Medicinal Processing(Lei Gong Pao Zhi Lun). The Sophora Flavescentis Radix pieces and the corresponding test samples in each processing stage were first prepared based on the processing method for Sophora Flavescentis Radix recorded in Master Lei's Discourse on Medicinal Processing(Lei Gong Pao Zhi Lun). Then the flavors and tastes of Sophora Flavescentis Radix test samples undergoing the soaking in rice-washed water, washing with clean water, and steaming for different time were compared with the electronic nose and tongue. The results showed that in the preparation of Sophora Flavescentis Radix with the ancient method, such processes as soaking in rice-washed water and washing with clean water had no significant influences on the flavor, which, however, was weakened by steaming. In terms of the taste, soaking with rice-washed water enhanced the bitter taste of Sophora Flavescentis Radix, which remained unchanged after being washed with the clean water. The steaming would also diminish the bitter taste, making it taste similar to the original Sophora Flavescentis Radix medicinal materials. During the steaming for six to eight hours, the flavor did not vary significantly over time, while the bitter taste was first weakened and then intensified. The bitter taste of Sophora Flavescentis Radix steamed for six hours was similar to that steamed for eight hours. In addition, the differences in flavor and taste between Sophora Flavescentis Radix pieces processed by the ancient method in Master Lei's Discourse on Medicinal Processing(Lei Gong Pao Zhi Lun)and those by the modern method in the 2020 edition of Chinese Pharmacopoeia were analyzed. The findings demonstrated that the flavor of Sophora Flavescentis Radix pieces prepared by the ancient method was weaker than that by the modern method, whereas the bitter taste showed the opposite trend. The exploration on the flavor and taste change rules of Sophora Flavescentis Radix in its preparation by the ancient classical method and the differences in flavor and taste between Sophora Flavescentis Radix decoction pieces prepared by ancient and modern methods will lay a foundation for further elucidation of the scientific connotation of the ancient processing method and the medication principles of Sophora Flavescentis Radix in both ancient and modern times.

Objective: To explore the associations of Hand-Foot-Mouth disease (HFM) among children of different age groups in kindergartens, and to provide scientific evidence for HFM prevention and control. Methods: Cluster sampling was used to select 9 912 children from 40 kindergartens. The major caregivers of children were invited to participate into the study and fulfill a self-administered questionnaire that consisted of general background, hand washing and the history of HFM among children in the recent 1 year. Chi-square and binary logistic regression were applied,to analyze the influencing factors of HFM among children of different age groups. Results: In the 2 year-old-group, children who were male (OR=1.76, 95%CI=1.24-2.50), had the major caregiver with high school educational background or below (OR=1.54, 95%CI=1.06-2.24), had family income more than 100 000 yuan or more per year(OR=1.49, 95%CI=1.01-2.20), children whose major caregiver seldom wash hands immediately after coming home(OR=2.10, 95%CI=1.05-4.19)，and 3-5 times per week(OR=2.07, 95%CI=1.26-3.41) were more likely to have HFM. In the 3 year-old-group, the more time children spent in the outdoors, the less likely they got HFM(3-5 times per week: OR=0.58, 95%CI=0.43-0.81; ≥6 times per week: OR=0.45, 95%CI=0.29-0.70). Children whose major caregiver did not use soap were more likely to have HFM(OR=1.67, 95%CI=1.11-2.49). In the 4 year-old-group, children who occasionally took toys when going out were less likely to get HFM (vs always, OR=0.57, 95%CI=0.38-0.88). No significant factors were found in the 5 year-old-group. Conclusion The behaviors and activities of major caregivers and children could influence the HFM incidence.To prevent HFM, it was advised that the major caregivers should wash hands immediately after coming home, and develop the habit of using soap for handwashing together with children at the earlier age, and encourage children to take more outside-door activities according to the age characteristics. Attention should be paid to avoid contaminating takeout snacks, and to clean the takeout toys timely.

Objective:To compare the clinical effect of percutaneous sacroiliac screw fixation assisted by O-arm navigation or C-arm X-ray fluoroscopy in the treatment of sacroiliac joint complex injury.Methods:A retrospective case-control study was conducted on 32 patients with sacroiliac joint complex injury admitted to Second Affiliated Hospital of Army Medical University from July 2016 to January 2019.There were 21 males and 11 females, aged from 20 to 59 years (mean, 41.3 years). According to Tile classification, there were 7 patients with type B1 fracturs, 13 with type B2, 5 with type B3, 5 with type C1, and 2 with type C1. Group A ( n=17) had percutaneous sacroiliac screw fixation assisted by O-arm navigation, while Group B ( n=15) had percutaneous sacroiliac screw fixation assisted by C-arm X-ray fluoroscopy. Time of single screw placement, time of intraoperative fluoroscopy, intraoperative bleeding volume and bone union time were measured. Reduction quality was evaluated by Matta standard score. Majeed function score was assessed 6 months at the latest follow-up. Complications were also observed. Results:All patients were followed up for 6-37 months (mean, 18.6 months). The time of sacroiliac joint screw placement [(27.3±5.1)minutes] and time of intraoperative fluoroscopy [(43.3±3.2)s] in Group A were significantly less than those in Group B [(52.3±5.9)minutes, (64.6±5.4)s] ( P<0.05). There were no significant differences between Group A and Group B in intraoperative bleeding [(17.8±2.6)ml vs. (20.7±3.1)ml] and bone union time [(13.4±1.4)weeks vs. (14.1±1.9)weeks] ( P>0.05). According to the reduction quality evaluated by Matta standard score, the good and excellent rate was 88% (15/17) in Group A and 87% (13/15) in Group B ( P>0.05). The good and excellent rate of the Majeed function score was 94% (16/17) in Group A and 87% (13/15) in Group B at the latest follow-up ( P>0.05). One patient in Group B demonstrated one screw slightly penetrating the anterior cortex of vertebral body. No neurovascular injury, wound infection, or screw loosening occurred. Conclusion:For sacroiliac joint complex injury, percutaneous sacroiliac screw fixation assisted by O-arm navigation has advantages in the duration of screw placement and intraoperative fluoroscopy over percutaneous sacroiliac screw fixation assisted by C-arm X-ray fluoroscopy.

OBJECTIVE: To compare clinical effect of dynamic locking screws and common screws in treating humeral shaft fractures. METHODS: From January 2016 to October 2018, clinical data of 46 patients with humeral shaft fracture were retrospectively analyzed, which were divided into dynamic locking screw internal fixation group (treatment group) and ordinary screw internal fixation group (control group). In treatment group, there were 14 males and 10 females, aged from 20 to 61 years old with an average of (36.8±10.9) years old;22 patients in control group, there were 13 males and 9 females, aged from 19 to 60 years old with an average of (35.9±12.8) years old. Length of incision, operation time, amount of bleeding, fracture healing time and complications were compared between two groups, Constant-Murley score of shoulder joint and Mayo score of elbow joint at 3 and 9 months after operation were compared to evaluate clinical effect. RESULTS: Forty six patients were followed up from 9 to 43 months with an average of (18.6±7.9) months. There were no statistical differences in length of incision, operation time, amount of bleeding between two groups (>0.05);fracture healing time in treatment group was (12.2±3.2) weeks, and (15.6±4.7) weeks in control group;there was difference between two groups (<0.05). Constant-Murley score and Mayo score of elbow joint at 3 months after operation in treatment group were 84.9±5.9 and 81.8±6.7, while in control group were 74.6±9.2 and 71.5±10.7;there were differences between two groups (<0.05). There were no statistical differences in Constant-Murley score and Mayo score of elbow joint between two groups at 9 months after operation (>0.05);One patient occurred neural paralysis in treatment group;1 patient occurred delayedunion, 2 patients occurred bone nonunion and 1 patient occurred broken nail in control group;while there was no statistical difference between two groups in complication. CONCLUSION Both of dynamic locking screws and ordinary screws could effectively treat humeral shaft fractures. dynamic locking screws has an advantage in fracture healing time, and recovery of early shoulder and elbow function. However, the active time of this technology is not too long in China, further study on long-term efficacy of large samples is needed.

Objective: To analyze the features of Norovirus outbreaks in schools and kindergartens and the associated factors in Chengdu, 2017, and to provide the scientific basis for Norovious outbreaks prevention and control. Methods: A total of 75 schools and kindergartens in Chengdu of 2017 participated in the study about Norovirus outbreaks. ANOVA and binary Logistic regression models were used to analyze the influencing factors and duration of Norovirus outbreaks. Results: Overall 710 cases were included. There was an average of 9.47 cases and 27.52 hours for each outbreak,decreasing by 1.06 cases and 10.56 hours compared with those of 2016. Most outbreaks happened in kindergartens and in the firstlevel economy regions from January to March, with GII type as the main outbreak. Compared with the first case of vomiting at home, vomiting in public area (OR=11.76, 95%CI=1.63-84.69) was much more serious, and compared with the active report of school/ community, being informed of the outbreak passively (OR=4.09，95%CI=1.04-16.03) was positively associated with outbreak severity. Conclusion To prevent Norovirus infection, specific development and training of dealing with vomiting and feces should be introduced, and measures to increase the ability to surveil and report Norovirus outbreaks should be enhanced.
