Objective:To investigate the effect of ultrasound-guided thoracic paravertebral nerve block (TPNB) on anesthesia efficacy and stress response in middle-aged and elderly patients undergoing radical surgery for lung cancer.Methods:A total of 104 lung cancer patients who underwent thoracoscopic radical resection for lung cancer at Qingdao Traditional Chinese Medicine Hospital from November 2020 to May 2023 were selected and randomly divided into an observation group (52 cases) and a control group (52 cases) using a random number table method. The observation group received general anesthesia combined with ultrasound-guided TPNB anesthesia during surgery, while the control group received general anesthesia. Two groups of patients were compared in terms of surgical time, intraoperative blood loss, remifentanil and propofol dosage, fluctuation trends of mean arterial pressure (MAP) and heart rate (HR), pain levels in resting and coughing states after surgery, differences in serum stress response indicators [fasting plasma glucose (FPG), cortisol (Cor), norepinephrine (NE), epinephrine (E)] before and after surgery, and adverse reactions.Results:There was no statistically significant difference in surgical time, intraoperative blood loss, and single lung ventilation time between the observation group and the control group (all P>0.05). The usage of remifentanil and propofol in the observation group was lower than that in the control group, and the difference was statistically significant (all P<0.05). The MAP fluctuation changes at four time points before anesthesia induction, 30 minutes during surgery, 90 minutes during surgery, and after surgery in the observation group were smaller than those in the control group. Among them, the MAP at 30 minutes during surgery and 90 minutes during surgery was higher than that in the control group (all P<0.05); There was no statistically significant difference in HR fluctuations between the observation group and the control group at the four time points (all P>0.05). The Visual Analog Scale (VAS) scores of the observation group patients in resting and coughing states at 12 and 24 hours after surgery were lower than those of the control group at the same time point (all P<0.05). The serum Cor and E levels in the observation group were lower than those in the control group at 12 hours after surgery, and the serum NE levels were lower than those in the control group at 12 and 24 hours after surgery (all P<0.05). The incidence of adverse reactions caused by anesthesia in the observation group was lower than that in the control group ( P<0.05). Conclusions:The use of ultrasound-guided TPNB combined with general anesthesia in patients undergoing radical surgery for lung cancer is beneficial in reducing intraoperative blood pressure fluctuations, alleviating postoperative pain and stress response, and reducing adverse reactions caused by anesthesia.

Objective:To explore the application status and research hotspots of robotic surgery system in surgical nursing based on literature analysis.Methods:Relevant literature on the application with robotic surgical nursing as the subject word was retrieved from CNKI,Wanfang Data,and VIP Chinese website from 2013 to 2022.CiteSpace software was used to extract information on authors,research institutions,and keywords,the cooperative relationships and research hotspots in this field were discussed and analyzed.Results:A total of 875 Chinese articles published between 2013 and 2022 were retrieved,and 454 articles were finally included in the analysis after deduplication screening.From 2013 to 2022,the annual number of papers published in robotic surgical nursing increased year by year,decreased slightly in 2019,and increased rapidly from 2021 to 2022,with 70 and 90 papers,respectively.The top 10 keywords with highest to lowest frequency were nursing,robotics,nursing cooperation,surgical cooperation,laparoscopy,perioperative,complications,prostate cancer,surgical nursing care and surgery.The degree of collaboration among different research institutions and authors was weak.Research hotspots included nursing cooperation and perioperative complication care.The research mainly focused on nursing experience sharing and nursing model discussion,while there were fewer studies on nursing quality standards,training models and relevant nursing interventions.Conclusion:Analysis of the application status and research hotspots of surgical nursing of robotic surgical system based on CiteSpace visualization software,can understand the research hotspots and trends of robotic surgery in the field of nursing by various research institutions and literature authors in China,and provide reference for the research direction of robotic surgery nursing.

Objective:To establish a nomogram model for predicting positive resection margins after prostate cancer surgery, and to perform the corresponding verification, in order to predict the risk of positive resection margins after surgery.Methods:A total of 2 215 prostate cancer patients from The First Affiliated Hospital of Naval Medical University, Hospital, Peking University First Hospital, Peking University Third Hospital, Peking University, and First Affiliated Hospital of Xi′an Jiaotong University were included in the PC-follow database from 2015 to 2018, and a simple random sampling method was used. They were divided into 1 770 patients in the modeling group and 445 patients in the verification group. In the modeling group, the age (<60 years, 60 to 70 years, >70 years), PSA (<4 ng/ml, 4-10 ng/ml, 11-20 ng/ml, >20 ng/ml), pelvic MRI (negative, suspicious, positive), clinical stage of the tumor (T 1-T 2, ≥T 3), percentage of positive needles (≤33%, 34%-66%, >66%), Gleason score of biopsy pathology (≤6 points, 7 points, ≥8 points). Univariate and multivariate logistic analysis were performed to screen meaningful indicators to construct a nomogram model. The model was used for validation in the validation group. Results:The results of multivariate analysis showed that preoperative PSA level ( OR=2.046, 95% CI 1.022 to 4.251, P=0.009), percentage of puncture positive needles ( OR=1.502, 95% CI 1.136 to 1.978, P=0.002), Gleason score of puncture pathology ( OR=1.568, 95% CI 1.063 to 2.313, P=0.028), pelvic MRI were correlated ( OR=1.525, 95% CI 1.160 to 2.005, P=0.033). Establish a nomogram model for independent predictors of positive margin of prostate cancer. The area under the receiver operating characteristic (ROC) curve of the validation group is 0.776. The area under the ROC curve of the preoperative PSA level, percentage of puncture positive needles, puncture pathology Gleason score, pelvic MRI, postoperative pathology Gleason score were 0.554, 0.615, 0.556, 0.522, and 0.560, respectively. The difference between the nomogram model and other indicators was statistically significant ( P<0.05). Conclusions:The constructed nomogram model has higher diagnostic value than the preoperative PSA level, percentage of puncture positive needles, Gleason score of puncturing pathology, pelvic MRI, and postoperative pathological Gleason score in predicting positive margin.

Objective: To investigate the efficacy and safety of rapamycin in children with tuberous sclerosis complex (TSC) associated renal disease. Methods: A prospective self-control study was conducted. The clinical data of 92 children diagnosed with tuberous sclerosis complex associated kidney disease at the People′s Liberation Army General Hospital from January 2011 to January 2019 were collected. The long-term rapamycin treatment for all patients initiated at 1 mg/(m²·d), which was gradually adjusted to reach a blood concentration of 5-10 μg/L. The changes of the maximum diameter of renal lesions in children after rapamycin treatment were observed and analyzed with Wilcoxon test. Results: Ninety-two children, including 52 males and 40 females, who met the criteria were analyzed. Sixty patients had only renal angiomyolipoma(RAML), while 24 patients had only multiple renal cysts(MRC), and 8 patients had both lesions. The age of TSC diagnosis was 16.0 (7.0, 42.0) months, and the age of initial treatment with rapamycin was 63.5 (21.0, 103.0) months. The follow-up lasted for 12.0 (4.0, 23.0) months. Sequencing of TSC1 and TSC2 genes was performed in 54 children with TSC, including 3 patients (6%) with mutations in TSC1 gene and 51 patients (94%) with mutations in TSC2 gene. The maximum RAML diameter before treatment was 7.0 (4.0, 9.0) mm. The best effect reached at 3 months of treatment, with the diameter of 4.0 (0,7.0) mm. The maximum diameters at 6 months, 1 year and 1-2 years were 5.0 (0,9.8) mm, 5.0 (1.5, 8.5) mm, 5.5 (3.0, 9.0) mm, respectively, and were significantly different from the baseline (Z=-2.404,-2.350,-2.750,P=0.016,0.019,0.006, respectively). The maximum diameter after 2-3 years, and ≥3 years were 5.0 (3.9,7.0) mm and 6.0 (1.0, 11.0) mm, without significant difference from the baseline (Z=-0.856,-0.102,P=0.393,0.919, respectively).The maximum diameters of MRC after 3 months, 6 months, 1 year,1-2 years, 2-3 years, and ≥3 years were 11.0 (5.0, 14.0) mm,3.0 (0.0,11.0) mm,5.0 (0,21.0) mm,0 (0,14.0) mm,0 (0,10.0) mm, and 0 (0,18.3) mm, respectively, but were not significantly different rom the baseline (7.0 (5.0, 15.7) mm)(Z=-0.944,-1.214,-1.035,-1.896,-1.603,-1.214,P=0.345,0.225,0.301,0.058,0.109,0.225, respectively).Twenty-nine patients (32%) had oral ulcers during the entire treatment period, and no serious adverse reactions were observed. Conclusions Rapamycin could decrease the diameter of TSC-related RAML, but could not inhibit the growth of cysts. It is well tolerated in the treatment of renal diseases associated with tuberous sclerosis complex.

Human norovirus (NoV) is a member of the calicivirus family, can cause nausea, vomiting, abdominal pain and diarrhea as the main clinical symptoms of acute gastroenteritis. Human norovirus infection can be popular in the world, all ages, causing serious burden of disease. Due to the lack of suitable small animal models, there is still a lack of understanding of human immune to norovirus infection and pathogenesis. Murine norovirus (MNV) was originally isolated in immune deficient mice, and causes infection and epidemic in mice. MNV provides an alternative model to study human norovirus infection and the host intestinal immune mechanism. This article will elaborate on two aspects of innate immunity and adaptive immunity.

Objective: To analyze the current status of allergic adverse reactions caused by non-ionic iodinated contrast media in patients with coronary angiography (CAG).
Methods: A total of 1 225 patients who received non-ionic iodinated contrast media for CAG in our hospital from 2011-02 to 2013-09 were retrospectively studied. There were 52 patients suffered from allergic adverse reactions including 47 (90.38%) male and 5 (9.62%) female. The allergic reaction to iodixanol, iohexol, iopamidol and iopromide were in 34, 3, 3 and 12 patients respectively. The clinical symptoms and outcomes of allergic reaction in 4 iodinated contrast media were analyzed.
Results: There were 40/52 (76.92%) patients with mild allergic reaction, 11(21.15%) with moderate and 1 (1.92%) with severe reaction. 13 patients had the reaction within 1 hour of contrast media injection and 39 had the reaction between 1 hour to 3 days of contrast media injection. There 34 patients were cured by symptomatic and anti-allergic treatment, 1 patient was rescued from allergic shock and no death occurred.
Conclusion: Application of non-ionic iodinated contrast media in CAG is safe, while closely observe the allergic adverse reaction with the in time and symptomatic treatment is very important in clinical practice.

Objective: To analyze the relevant factors for combined use of low molecular weight heparin (LMWH) and statins causing transaminase elevation and to provide the reference for medication safety in clinical practice. Methods: There were 45 patients who received the combination of LMWH and statins treatment, then having ALT elevation in our ward from 2011-01 to 2012-12 were collected, by exclusion of patients with the history of high ALT at admission, interrupted treatment and incomplete record of liver function tests, a total of 32 patients were ifnally enrolled for investigation. The conditions for using LMWH and statins together, type of LMWH, timing of ALT elevation after medication and clinical outcomes were retrospectively analyzed. Results: All patients received statins including simvastatin, atorvastatin, rosuvastatin and pravastatin, and 15 patients took statins before using LMWH including enoxaparin, nadroparin and dalteparin. There were 18 patients had ALT increased below 3 times of the upper limit and 14 patients had ALT level ≥ 3 times of the upper limit, and ALT elevation occurred at the average of (3 ± 3.8) days after taking LMWH. All patients stopped using LMWH upon ALT elevation and 16 of them stopped taking statins. The ALT level gradually decreased to normal by application of hepatic-protective treatment in all patients.Conclusion: Combined using LMWH and statins could cause ALT elevation, LMWH and statins may have synergistic effect, and therefore, the enhanced monitor of liver function is necessary when using the combined medication.

Objective To investigate and analyze the usage of expensive outpatient prescriptions in different hospitals in Longgang area,Shenzhen,and to discuss and provide reference for the rational usage of expensive pre-scriptions.Methods Two primary hospitals,two secondary hospitals and one tertiary hospital in the Longgang area, Shenzhen,were chosen as the research targets.The expensive outpatient prescriptions,defined as the amount of pre-scription was over 150,200 and 300 yuan for primary,secondary and tertiary hospital respectively,were randomly selected and evaluated using international standards for the rational use of drugs.Results The average prescription items for primary,secondary and tertiary hospitals were 2.96,2.61 and 2.61.The largest proportions of prescription costs were 150 to 200 yuan,200 to 250 yuan and 300 to 350 yuan,which were respectively accounted for 49.6%, 56.6% and 37.7%.The frequency of using proprietary Chinese medicine,was 60.08%,68.18% and 41.62%respectively,which was not reasonable.The clinical diagnosis for the prescriptions of primary and secondary hospitals was mainly composed of trauma,bronchitis and vaginitis.The usage of drugs was not reasonable about the use of anti-biotics and infusion.In addition,the clinical diagnosis for the prescription of tertiary hospital was mainly diabetes, hypertension and cerebral infarction,where the abuse of using large dose of adjuvant drug was observed.Conclusion The frequency of using proprietary Chinese medicine is higher at all levels of hospital.In order to reduce the propor-tion of expensive prescription,the medicine institution should establish a sound system for drug use management and strengthen supervision and verification for western medicine physicians using proprietary Chinese medicine in their prescription.Furthermore,we should intervene and restrict the abuse usage of the adjuvant medicine.
