Objective To observe the changes of adrenal cortical function in children with growth hormone deficiency before and after treatment with recombinant human growth hormone. Methods Seventy-two children diagnosed with GHD who received rhGH treatment for no less than 6 month were included, among whom there were 32 children who were accompanied with adrenal cortical hormone (ACTH) deficiency. The changes of fasting plasma cortisol (COR) and ACTH levels before and 3 and 6 months after treatment with rhGH were retrospectively analyzed. Results Thirty-two children with ACTH deficiency were treated with rhGH after COR level reached normal by the supplementing exogenous hydrocortisone. There was negative correlation between COR level before treatment and the HC dose that make the COR reach normal lowest limit level (r?=?-0.899, P?0.01). One month after HC treatment only, the level of COR was obviously increased and ACTH was obviously decreased (P all?0.001). The levels of COR or ACTH at 3 or 6 months after rhGH and HC replacement therapy were not different from those at one month after HC treatment only (P all?>?0.05). The level of COR was obviously decreased after treatment with rhGH, and there was statistical difference compared with that before treatment (P?0.01) in 40 children without ACTH deficiency, among whom 10 children with abnormal hypothalamic pituitary MRI had lower level of COR. Conclusion Adrenal cortical function can be reduced during the treatment with rhGH in children with GHD, especially in children with abnormal hypophysis MRI. Thus, during the treatment period, adrenal cortical function should be monitored, so as to make early intervention.

Objective To evaluate the role of hypoxia inducible factor?1α ( HIF?1α) in reduction of apoptosis in cortical neurons of rats by sevoflurane preconditioning and the relationship with Slit2∕Robo signaling pathway. Methods Primary cortical neurons obtained from neonatal Sprague?Dawley rats were seeded in 6?well (2 ml∕well) or 96?well plates (100 μl∕well) at a density of 1×106∕ml, and randomly divided into 4 groups ( n=24 each ) using a random number table: control group ( C group ) , anoxia?reoxygenation ( A∕R ) group, sevoflurane preconditioning group ( SP group ) and HIF?1α inhibitor 2?methoxyestradiol group ( H group ) . The neurons were subjected to O2?glucose deprivation for 90 min followed by restoration of O2?glucose supply for 24 h. In group SP, the neurons were exposed to 2%sevoflurane for 2 h followed by 5 min washout with phosphate buffered saline for 3 times, and then sevoflurane preconditioning was performed immediately. In group H, sevoflurane preconditioning was performed with 5μmol∕L 2?methoxyestradiol at 72 h of incubation. The apoptosis in neurons was assessed using AnnexinⅤ?FITC∕PI assay, and apoptosis rate ( AR) was calculated. The amount of lactic dehydrogenase ( LDH) released was measured using colorimetric method. The expression of Slit2, Robo1 and Robo4 mRNA and protein was detected by fluorescent quantitative real?time polymerase chain reaction or Western blot. Results Compared with group C, the amount of LDH released and AR were significantly increased, Silt2 and Robo1 mRNA and protein expression was up?regulated, and no significant change was found in Robo4 mRNA and protein expression in A∕R group. Compared with group A∕R, the amount of LDH released and AR were significantly decreased in SP and H groups, and Silt2 and Robo1 mRNA and protein expression was up?regulated, and no significant change was found in Robo4 mRNA and protein expression in SP group. Compared with group SP, the amount of LDH released and AR were significantly increased, and Silt2 and Robo1 mRNA and protein expression was down?regulated in H group. Conclusion HIF?1α mediates reduction of apoptosis in cortical neurons of rats by sevoflurane preconditioning, and the mechanism is associated with Slit2∕Robo1 signaling pathway, but not with Slit2∕Robo4 signaling pathway.

Objective To seek the predictive value of pudendal nerve function that need preventive anti-incontinence surgery at the same time following pelvic prolapse surgery in severe pelvic organ prolapse (POP) patients. Methods Seventy women completed this study from January 2014 to June 2015 in Fuzhou General Hospital of Nanjing Military Command, dividing into four groups: POP with or without coexisting occult stress urinary incontinence (OSUI) in preoperation, women with persistent stress urinary incontinence (SUI) in postoperation, women without SUI in postoperation. The pudendal nerve function in preoperation was measured by using Solar Urodynamic Neuro Module, including pudendal nerve terminal motor latency (PNTML), and amplitude. Results There were statistical significance on bilateral PNTML between POP coexisting OSUI group and only severe POP group [(2.62±0.23) versus (2.40±0.26) ms in right of PNTML, (2.55 ± 0.21) versus (2.37 ± 0.30) ms in left of PNTML; all P<0.05], but no statistical significance on bilateral amplitude (P>0.05). Compared de novo SUI group with POP group in postoperation, de novo SUI group′s right of PNTML was significantly increased [(2.74 ± 0.16) versus (2.47 ± 0.26) ms; P<0.05]; and the right of PNTML was extending 2.5 standard deviation at least compared with the health′s [(2.10±0.20) ms]. Conclusions The PNTML of pudendal nerve of POP coexisting OSUI is severe than only severe POP, the velocity of nerve conduction is slowing, and PNTML extension has a predictive value for postoperative urinary incontinence. When the right of PNTML of preoperative POP increased by at least 2.5 standard deviations than health′s, the risk of SUI postoperative strongly increased, and a anti-incontinence surgery at the same time following pelvic prolapse surgery should be adviced.

Objective To develop a computer-aided-controlling and analysis system for light/dark box in mice and rats with a high degree of automation and intelligence.Methods Video recording and image processing were applied to develop the computer-aided-controlling and image analysis system for light/dark box test in mice and rats. The artificial environment was developed. The stability and reliability of the system was validated by male rats. Results The percentage of time spent in the lit chamber in total time was above 79.40%. The data showed that the artificial environment was successful. When the threshold was set at 18 cm/s, the data showed a high correlation coefficient of movement time between the computer and manual recordings(r > 0.99). Classical indexes including transition and time spent in both the lit and dark chambers also showed a high correlation. The model group showed a significantly decrease in the transitions and time spent in the lit chamber compared with the control group, indicating a high stability and reliability of the light/dark box test. Conclusions A stable and highly intelligent computer-aided-controlling and image analysis system for light/dark box test of mice and rats has been developed,and it could be used for pathological mechanism studies of anxiolytics.

Objective:To explore the effects of information drug close-loop management mode on adverse events of nursing medication and to analyze the 46 cases of adverse events after implementing the information drug close-loop management mode so as to understand the event characteristics and formulate the countermeasures with the aim to reduce the nursing medication errors.Methods:We retrospectively analyzed the 46 cases of adverse events of nursing medication reported by system in the First Affiliated Hospital of Xiamen University after implementing the information drug close-loop management mode (from January to December 2018) . Among the 46 cases of events, we analyzed the classifications, causes and links of error and compared those events with adverse events of nursing medication before implementing the information drug close-loop management mode in 2017.Results:After carrying out the drug close-loop management, the adverse events of medication declined compared with that in 2017, but there was no statistical difference ( P>0.05) . The adverse events included 17 (17/46, 36.96%) errors in identification, 8 (8/46, 17.39%) medication omissions, 7 (7/46, 15.22%) errors in dose and 5 (5/46, 10.87%) errors in route. The links of medication errors were mainly in drug dispensing (26 cases) and arranging (14 cases) . Conclusions:Adverse events of medication most often occur in drug dispensing. The most common errors were misidentification. Nursing managers should formulate the preventive intervention based on the classifications and characteristics of adverse events in nursing medication administering, and monitor as well as improve the rate of sweeping code in drug close-loop, strength training for nurses, and check the drug dispensing and arranging well.

Objective:To investigate the effect of perioperative intervention based on theory of planned behavior on postoperative complications and quality of life of patients undergoing endoscopic retrograde cholangiopancreatography (ERCP) combined with laparoscopic cholecystectomy.Methods:Taking the implementation time of perioperative intervention based on theory of planned behavior (July 2018) in the hospital as the cut-off point, 60 patients with common bile duct stones who needed ERCP combined with laparoscopic cholecystectomy from December 2017 to June 2018 were selected as the control group and they were given routine nursing intervention. And 60 patients with common bile duct stones requiring ERCP combined with laparoscopic cholecystectomy from July 2018 to December 2020 were enrolled as the observation group and they adopted perioperative intervention based on theory of planned behavior. The perioperative rehabilitation indicators, degree of pain at 24 hours after surgery [Short-form McGill Pain Questionnaire-2 (SF-MPQ-2) ] , the psychological state [Generalized Anxiety Disorder-7 (GAD-7) , Patient Health Questionnaire-9 (PHQ-9) ] , healthy behaviors [Health Promotion Lifestyle Profile-Ⅱ (HPLP-Ⅱ) ] , health literacy [Chinese Citizens' Health Literacy Questionnaire] and quality of life [Gastrointestinal Quality of Life Index, GIQLI] before intervention and at discharge were compared between the two groups. The occurrence of complications was compared.Results:There was no statistically significant difference in the operation time, intraoperative blood loss and hospitalization time between the two groups ( P>0.05) . The postoperative ventilation time of the observation group was lower than that of the control group ( P<0.05) . At 24 hours after operation, there was no statistically significant difference in the SF-MPQ-2 scores between the two groups ( P>0.05) . At discharge, the GAD-7 and PHQ-9 scores of the observation group were lower than those of the control group and the same group before the intervention, while the HPLP-Ⅱ score, health literacy and GIQLI score were higher than those of the control group and the same group before the intervention ( P<0.05) . There was no statistically significant difference in the incidence of complications between the two groups ( P>0.05) . Conclusions:Perioperative intervention based on the theory of planned behavior can promote the postoperative recovery of patients undergoing ERCP combined with laparoscopic cholecystectomy and improve their psychological state, health literacy and behavior and quality of life.

Objective:To evaluate the relationship between the mechanism by which aucubin improved attention deficit hyperactivity disorder (ADHD) induced by maternal exposure to S-ketamine and GABAergic neurons in the habenular nucleus of offspring mice.Methods:SPF healthy C57BL/6 wild-type pregnant mice were used in this study, and an ADHD model in offspring mice was established by intraperitoneally injecting S-ketamine in the middle and late pregnancy. Twenty-four offspring of pregnant mice exposed to S-ketamine were divided into 2 groups ( n=12 each) at 14 days after birth using a random number table method: ADHD + normal saline group (AN group) and ADHD + aucubin group (AA group). Twenty-four offspring of pregnant mice exposed to normal saline were divided into 2 groups ( n=12 each) at 14 days after birth by a random number table method: control + normal saline group (CN group) and control + aucubin group (CA group). Aucubin 40 mg/kg was intraperitoneally injected once a day for 7 consecutive days in CA group and AA group, and the equal volume of normal saline was given instead in CN group and AN group. At 14 days after birth, the 16-channel microfilament array electrode was placed in the habenular nucleus, and the ratio of excitatory neurons to inhibitory neurons in the habenular nucleus was recorded when the mice buried beads in the marble burying test. At 21 days after birth (after the end of peritoneal administration), the impulsive and stereotypical behaviors of offspring mice were evaluated by elevated zero maze and marble burying test, respectively, and then the expression of glutamate decarboxylase 2 (GAD2) in habenular nucleus was detected by the immunofluorescence method. Results:Compared with CN group, the ratio of excitatory neurons to inhibitory neurons in the habenular nucleus was significantly increased, the expression of GAD2 was down-regulated, the time spent in the open arm was prolonged, the number of entries into the open arm and the number of buried beads were increased in AN group ( P<0.05), and no statistically significant differences were found in the above indexes in CA group ( P>0.05). Compared with AN group, the ratio of excitatory neurons to inhibitory neurons in the habenular nucleus was significantly decreased, the expression of GAD2 was up-regulated, the time spent in the open arm was shortened, and the number of entries into the open arm and the number of buried beads were decreased in AA group ( P<0.05). Conclusions:The mechanism by which aucubin alleviates prenatal S-ketamine exposure-induced ADHD may be related to increasing the number of GABAergic neurons in the habenular nucleus of offspring mice.

Objective:To investigate the clinical effect of using combined lumbar pelvis fixation device in the treatment of old vertical unstable fracture dislocation of posterior pelvic ring.Methods:Data of 7 patients with old vertical unstable fracture dislocation of posterior pelvic ring admitted and followed up from January 2017 to April 2020 were retrospectively analyzed, including 4 males and 3 females with an average age of 42.4 years old (range, 22-73 years old). There were 3 cases of traffic injury, 3 cases of falling injury and 1 case of tumble injury. According to Tile classification for pelvic fractures, there were 5 cases of type C1, 1 case of type C2 and 1 case of type C3. The average time from fracture to surgery was 5.4 weeks (range, 3-10 weeks). Among the 7 patients, 4 patients' posterior ring fractures were fixed by combined lumbar pelvic triangle fixation, and 3 patients' posterior ring fracture were fixed by combined lumbar pelvic fixation. 4 patients' anterior ring injury were not treated, 2 patients' anterior ring injury were treated by closed cannulated screw and internal fixation, and 1 patient's anterior ring injury was fixed by INFIX and cannulated screw. Every patient's operating time, intraoperative blood loss, length of incision and times of X-ray fluoroscopy were recorded. Pelvic X-ray and CT scan were taken postoperatively to observe the condition of reduction and screw position. Postoperative fracture reduction quality was assessed by Matta radiological criteria and Majeed criteria was used at the final follow-ups to evaluate the degree of functional recovery after pelvic fracture.Results:The average operating time of 7 patients was 143 min (range, 96-205 min); the intraoperative average blood loss was 579 ml (range, 300-1 650 ml); the average length of incisions was 12.9 cm (range, 9-15 cm) and the average time of X-ray fluoroscopy was 27 times (range, 15-52 times). Postoperative X-ray and CT scan showed that the displacements of the posterior rings were reset well and all the hollow screws were located accurately and firmly. Postoperative radiation quality was evaluated according to Matta radiological criteria, and there were 4 cases of excellent, 2 cases of good and 1 case of fair, with an excellent and good rate of 85.7% (6/7). Seven patients had good fracture union. The average followed up time for all 7 patients was 12 months (range, 6-16 months). At the last follow-up, imaging examination showed good reduction of the sacroiliac joint, and the reduction of anterior and posterior rings were not lost. The healing time was 14.2 weeks (range, 12-20 weeks). Majeed score: postoperative 4.90±6.64 points (range, 48-58 points), postoperative 3 months 71.40±7.32 points (range, 67-75 points), postoperative 6 months 84.90±8.14 points (range, 68-96 points), the difference was statistically significant ( F=0.614, P=0.004). Majeed score 6 months after operation showed that 5 cases were excellent, 1 case was good and 1 case was fair, and the excellent and good rate was 85.7% (6/7). Conclusion:Using combined lumbar pelvis fixation device in the treatment of old vertical unstable fracture dislocation of posterior pelvic ring has good reduction quality, high fixed strength and good postoperative effect.

Objective:To investigate the icariin on cognitive function and astrocytic pyroptosis in hemorrhagic shock resuscitation model mice.Methods:Forty-eight SPF grade C57BL/6 mice (male) were randomly divided into four groups ( n=12 in each group): Sham operation control group (Group C), hemorrhagic shock and resuscitation group (Group H), hemorrhagic shock and resuscitation plus icariin group (Group HI) and hemorrhagic shock resuscitation plus icariin and SSK1 group (Group HIS, SSK1 was a phosphorylation agonist of mitogen-activated protein kinase p38(p38MAPK). The mice in Group H, HI and HIS were subjected to hemorrhagic shock and resuscitation model by bleeding and retransfusion via left femoral vein; the mice in Group HI and HIS were administered with icariin (10 mg/kg) intragastrically for 7 days; the mice in Group C and H were administered with the same amount of normal saline containing dimethyl sulfoxide(DMSO). The mice in Group HIS were administered with SSK1 (0.5 mg/kg) intraperitoneally, but the mice in Group C, H and HI were only administered with the same amount of normal saline containing DMSO.At 15 days after resuscitation, novel objective recognition test and fear conditioning test were used to assess cognitive dysfunction of mice.Microtubule-associated protein 2(MAP2), a specific marker protein of neurons reflecting astrocytic pyroptosis in the hippocampus of mice, were detected by immunofluorescence assay so as to assess neuronal injury and astrocytic pyroptosis.The levels of IL-1β, IL-18, the ratio of phosphorylated p38MAPK to total p38MAPK in the hippocampus were evaluated by Western blot.SPSS 21.0 software was used for data analysis, multiple samples among groups were compared by one-way ANOVA, and SNK- q test was used for further pairwise comparison. Results:The results of new object recognition test showed that the difference of new object recognition index among the four groups was statistically significant ( F=50.75, P<0.05). The new object recognition indexes in H group(22.7±6.9), HI group(40.1±7.0) and HIS group (22.5±7.5) were significantly lower than that in C group (58.5±11.2). The index in HI group was higher than that in H group, while the index in HIS group was lower than that in HI group (all P<0.05). The results of the fear conditioning test showed that there was a statistically significant difference in the percentage of freezing time among the four groups of mice ( F=60.54, P<0.05). And the percentage of freezing time in H group((21.8±5.0)%), HI group ((38.4±7.4) %)and HIS group((21.3±4.2)%)were lower than that in C group((49.1±7.0)%), which in HI group was higher than that in H group ( P<0.05)and which in HIS group was lower than that in HI group(all P<0.05). The results of immunofluorescence showed that there were significant decreases of MAP2 intensity ((35.3±9.3)%, (63.3±6.1)%, (28.7±10.3)%) but increases of pyroptotic astrocytes ((24.5±4.2)%, (9.3±1.5)%, (22.1±3.3)%) in the H, HI and HIS groups compared with those of C group ((106.7±19.7) %, (3.4±2.0)%). There was an increase of MAP2 intensity but a decrease of pyroptotic astrocytes in the HI group compared with those in H group, and there was a decrease of MAP2 intensity but an increase of pyroptotic astrocytes in the HIS group compared with those of HI group (all P<0.05). The Western blot results showed that there were significant increases of IL-1β, IL-18, the ratio of phosphorylated p38MAPK to total p38MAPK in the H, HI and HIS groups compared with C group, there were decreases of IL-1β, IL-18, the ratio of phosphorylated p38MAPK to total p38MAPK in the HI group compared with H group, and there were increases of IL-1β, IL-18, the ratio of phosphorylated p38MAPK to total p38MAPK in the HIS group compared with those in HI group (all P<0.05). Conclusion:Icariin alleviates hemorrhage shock and resuscitation-induced cognitive dysfunction and astrocytic pyroptosis in mice, and the mechanism may be associated with inhibition of phosphorylated p38MAPK.

Objective:To explore the risk factors of adjacent segment diseases (ASDis) after lumbar fusion, summarize the prevention strategies and provide reference for clinical treatment.Methods:All of 258 patients who underwent lumbar interbody fusion from March 2014 to March 2019 were retrospectively analyzed, including 95 males and 163 females, the age of whom was 61.8±8.4 years (range, 39-77 years). The patients were divided into ASDis group and non-ASDis group according to whether ASDis occurred at the follow-up of 24 months after operation. The patient's individual factors [gender, age, body mass index (BMI), main diagnosis, preoperative paraspinal muscle fatty degree, etc.] and surgical factors (operation type, fixed segment, fusion segment, etc.), sagittal parameters [lumbar lordosis (LL), pelvic incidence (PI), pelvic tilt (PT), sacral slope (SS), PI-LL] were recorded. After univariate analysis of potential risk factors, the factors with P<0.05 were substituted into logistic regression model for multivariate analysis to determine the risk factors of ASDis after lumbar fusion. Results:ASDis occurred in 24 patients after lumbar fusion, with an incidence of 9.3% (24/258); univariate analysis showed that age ≥ 60 years old, complicated with osteoporosis, preoperative fatty degree of paraspinal muscle (GCS grade≥3), PLIF operation, suspension fixation, total laminectomy and multi-segment fusion (≥ 3 segments) were the potential risk factors for ASDis after operation (P<0.05); Gender, education level, partner status, type of work, BMI, obesity (BMI≥24 kg/m 2) , smoking, use of bisphosphonates, concomitant lumbar spinal stenosis, lumbar lordosis angle, pelvic incidence angle, pelvic tilt angle, sacral slope angle, and PI-LL had no significant correlation with ASDis. Logistic regression analysis showed that age ≥ 60 years ( OR=5.63, 95% CI: 1.56, 20.29, P=0.008), preoperative paravertebral muscle fatty GCS ≥ 3 ( OR=4.82, 95% CI: 1.36, 17.13, P=0.015), combined with osteoporosis ( OR=14.04, 95% CI: 2.53, 77.79, P=0.002), PLIF ( OR=9.69, 95% CI: 1.91, 49.03, P=0.001), and multi-segment fixation ( OR=9.36, 95% CI: 1.77, 49.41, P=0.008) were the risk factors for ASDis after lumbar fusion; Incomplete laminectomy ( OR=0.09, 95% CI: 0.02, 0.37, P=0.001) and suspension fixation ( OR=0.16, 95% CI: 0.02, 0.94, P=0.042) were the protective factors of ASDis after lumbar fusion. Conclusion:The patients with age ≥ 60 years old, osteoporosis and preoperative paraspinal muscle fatty degree ≥ 3 grade GCS should be more careful in choosing the surgical methods, and try to choose transforaminal interbody fusion, posterolateral fusion, short segment fusion, decompression with preservation of vertebral lamina, suspension fixation and other surgical methods to reduce the incidence of postoperative ASDis.
