Objectives:To explore the relationship between insomnia symptoms and neuroticism in patients with COVID-19,and to explore the role of anxiety and psychological capital in the relationship.Methods:Totally 687 patients with COVID-19 were recruited from Shanghai Fangcang Hospital.The Athens Insomnia Scale(AIS),Eysenck Personality Questionnaire-Revised Short Scale for Chinese Neuroticism Subscale(EPQ-RSC-N),Self-Rat-ing Anxiety Scale(SAS)and Psychological Capital Questionnaire(PCQ)were used to measure insomnia symp-toms,neuroticism personality trait,anxiety symptoms and psychological capital levels.The deviation-corrected per-centile Bootstrap method was used to test the mediating effect,and the PROCESS program was used to test the moderated effect.Results:The detection rate of insomnia symptoms was 49.93％.The AIS scores were lower in male patients than in female patients(P＜0.01).The SAS scores partly mediated the relationship between neuroti-cism scores and AIS scores,with an effect size of 0.03,accounting for 18.29％of the total effect.With the im-provement of PCQ scores,the predictive effect of SAS scores on AIS scores gradually decreased(β=-0.01,t=-4.41,P＜0.001).Conclusions:Anxiety symptoms in patients with COVID-19 play a partial mediating role in the positive relationship between insomnia symptoms and neuroticism.The psychological capital moderates the relation-ship between insomnia and anxiety symptoms.

At present,in medical academic circle there is no consensus on the optimal diameter of the stent used in transjugular intrahepatic portosystemic shunt(TIPS).In 2021,the Advancing Liver Therapeutic Approaches Consortium(ALTAC)recommended the use of controllable diameter TIPS covered stent system in the performance of TIPS,the stent diameter of this system can be adjusted within the range of 8 mm to 10 mm,and its stability can be maintained for a long time.This system carries several advantages such as accurately regulating portal venous pressure gradient(PPG),optimizing hemodynamic target,protecting liver blood perfusion,reducing shunt-related complications,etc.,indicating that this system has a promising clinical application prospect.Through reviewing the relevant literature,this paper summarizes the research progress of controllable diameter TIPS covered stent system,aiming to better help clinicians engaged in related fields to gain a further understanding of this new technology.

Diabetes, hypertension, and dyslipidemia, collectively referred to the " Three Highs, " represent increasingly prevalent metabolic risk factors in China. Many individuals experience all three conditions concurrently, significantly heightening the risk of cardiovascular disease and mortality. Although the National Metabolic Management Center(MMC) has been established for over eight years and has its unique features, the awareness, treatment, and control rates of these diseases in China remain low, and the efficiency of community management is insufficient. According to the previous two editions of management guidelines and the most recent domestic and international diagnostic and treatment guidelines, this paper conducts an in-depth analysis of the operational experience and management strategies of the MMC. Its aim is to improve the efficiency of grassroots MMC mode management for " Three Highs" patients and ensure that patients receive more standardized management.

Objective To investigate the current situation of skin tests for β-lactams in 155 hospitals in Beijing.Methods The questionnaires were sent to medical institutions in Beijing to statistically described the current situation of β-lactams skin test,and the relevant influencing factors were analyzed by Fisher exact test,and Chi-square test.Results A total of 3 097 questionnaires were received from 155 medical institutions,of which 3 057 were valid questionnaires(effective rate is 98.71％).In this study,122 hospitals conducted skin test before using intravenous penicillins,accounting for 99.19％of 123 hospitals with intravenous penicillins.Hospitals with infectious disease pharmacists conducted more skin tests before using intravenous penicillins(98.59％vs 88.46％,P＜0.001),and some hospitals didn't conduct skin tests before using oral penicillins.Seventy hospitals(45.16％)had not yet cancelled skin tests for cephalosporins,more hospitals with infectious disease pharmacists cancelled routine skin test(59.74％vs 50.00％,P＜0.05),and more tertiary hospitals cancelled cephalosporin skin test(80.65％vs 51.40％,29.41％,all P＜0.01).After the promulgation of the"Guiding Principle for Skin Test of β-lactams(2021 edition)",more primary hospitals have developed or updated the rules or regulation for skin test of β-lactams according to the Guiding Principle,compared with secondary hospitals(72.22％vs 41.18％,P＜0.05).Hospitals with infectious disease pharmacists developed or updated the rules or regulation for skin test of β-lactams in their hospitals(78.57％vs 60.00％,P＜0.05).Infectious disease pharmacists had promoting effect on the publicity of the rules or regulation of skin test in the hospital(92.65％vs 80.46％,P＜0.05).Conclusion Many hospitals in Beijing have not cancelled cephalosporins skin test,and the current situation of cancelling cephalosporins skin test in tertiary hospitals is better than that in primary and secondary hospitals.

【Objective】 To investigate the clinical effects of treatment of single-segment lumbar tuberculosis by oblique lateral interbody fusion with autologous iliac bone and percutaneous pedicle screw fixation. 【Methods】 We collected the clinical data of 47 patients with lumbar tuberculosis treated in The First Affiliated Hospital of Xi’an Jiaotong University from March 2017 to January 2020. Among them， 22 patients underwent oblique lateral interbody fusion with autologous iliac bone and percutaneous pedicle screw fixation （minimally invasive group） and 25 patients underwent open surgery combined anterior-debridement and posterior-fixation （control group）. The related data were collected， including gender， sex， body mass index （BMI）， systemic symptoms of tuberculosis， operation duration， intraoperative bleeding， postoperative drainage， hospital stay， complications， visual analogue score （VAS）， erythrocyte sedimentation rate （ESR）， and Oswestry disability index （ODI）. 【Results】 Baseline clinical characteristics did not significantly differ between the two groups （P>0.05）. Compared with control group， the minimally invasive group had shorter operation duration ［（188.64±18.59） min vs. （201.60±22.67） min］， less intraoperative blood loss ［（118.64±22.95） mL vs. （553.60±100.54） mL］， less postoperative drainage ［（134.55±36.48） mL vs. （291.20±61.53） mL］， and shorter hospitalization time ［（12.86±2.17） d vs. （15.80±3.03） d］ （all P<0.05）. However， there was no significant difference in fusion time or complication rate （P>0.05）. Compared with the preoperative ones， ESR， VAS score and ODI score significantly decreased and Cobb angle significantly increased in both groups （all P<0.001）. At postoperative 3 months， the VAS score was lower in the minimally invasive group than in control group ［（3.59±0.96） vs. （4.16±0.85）］ （P<0.05）. With regard to other characteristics， there was no significant difference between the two groups at the same point （P>0.05）. 【Conclusion】 Both minimally invasive technique and open surgery can achieve excellent clinical results， but the minimally invasive technique can reduce the surgical trauma and shorten the hospitalization time.

Objective:To explore the effect and mechanism of Guizhitang with different proportions of Cinnamomi Ramulus and Paeoniae Alba Radix on overactive cardiac sympathetic nerves in salt-sensitive hypertensive rats. Method:Randomly divide the forty male 6-week-old salt-sensitive hypertensive rats into five groups： the normal control group， the model group， the Cinnamomi Ramulus and Paeoniae Alba Radix 1∶1 group， the Cinnamomi Ramulus and Paeoniae Alba Radix 1∶2 group，and the Cinnamomi Ramulus and Paeoniae Alba Radix 2∶1 group， each group has 8 animals， the normal control group was fed with low-salt feed， and the remaining four groups were fed with 8% high-salt feed. After 4 weeks of feeding， gastric feeding was started. Give both the normal control group and model group saline and the Cinnamomi Ramulus and Paeoniae Alba Radix 1∶1 group， the 1∶2 group，and the 2∶1 group， were given Guizhitang aqueous solution at 4.0， 5.5 and 5.5 g·kg^-1， respectively. Continuous gavage intervention was held for 4 weeks. IITC multi-channel non-invasive sphygmomanometer was used to detect changes of systolic blood pressure before and after treatment in rats. Left ventricular anterior wall end-diastolic thickness （LVAWd） and interventricular septal diastolic thickness （IVSd） were detected by echocardiography. Hematoxylin-eosin（HE）staining and Masson staining were used to observe the myocardial morphological changes of rats in each group， Western blot was used to detect the expression of nerve growth factor （NGF）， growth-associated protein 43 （GAP43） and tyrosine hydroxylase （TH） protein. Result:After 4 weeks of intervention with Guizhitang， compared with the normal control group， the blood pressure， LVAWd and IVSd of the model group were significantly increased， and the expressions of NGF， TH and GAP43 protein were significantly increased （P<0.01）. HE and Masson staining results showed that the model group had myocardial cell edema， a large number of inflammatory cell infiltration， myocardial fiber hyperplasia and disordered arrangement， and a large amount of collagen deposition could be seen in the intercellular substance. Compared with model group， the systolic blood pressure of rats in each Guizhitang group increased slowly， and the expression of NGF， TH and GAP43 protein decreased （P<0.05，P<0.01），the Cinnamomi Ramulus and Paeoniae Alba Radix 1∶1 group has the best effect. The results of echocardiography shows that the 1∶1 Guishao group could reduce LVAWd and IVSd levels （P<0.05，P<0.01）， the Cinnamomi Ramulus and Paeoniae Alba Radix 1∶2 group could reduce IVSd level （P<0.05）， there was no statistical difference in LVAWd， there was no statistical difference in LVAWd and IVSd in 2∶1 group. In terms of myocardial morphology， each group of Guizhitang can reduce cell edema and inflammatory cell infiltration， reduce myocardial fiber hyperplasia and collagen deposition， and improve the disorder of myocardial fiber arrangement. Among them， the 1∶1 group has the best effect. Conclusion:Guizhitang can inhibit the overactive activation of cardiac sympathetic nervous system，reduce the extent of myocardial fibrosis， inflammatory infiltration and myocardial hypertrophy， and protect salt-sensitive hypertension rats， whose mechanism may be related to regulating the expression of heart NGF.Among them， the Cinnamomi Ramulus and Paeoniae Alba Radix 1∶1 group is better than the 1∶2 and 2∶1 group in reducing myocardial fibrosis， inflammatory infiltration and myocardial hypertrophy.
