Objective:To investigate the effects of Dexmedetomidine for supplemental anesthesia on perioperative hemodynamics and postoperative sedation and analgesia in elderly patients receiving radical gastric cancer surgery under general anesthesia.Methods:From January 2019 to April 2020, 63 patients admitted to our hospital for radical gastric cancer surgery were included as observation objects.They all underwent general anesthesia and were divided into the Dexmedetomidine group(odd-numbered group)and the normal saline group(even-numbered group)according to the parity of serial numbers the subjects were assigned to.Changes in perioperative hemodynamic index values and the amounts of anesthetic drugs used in the two groups were monitored and recorded, and postoperative sedation and analgesia effects were evaluated by using the Ramsay sedation scale and the visual analog scale(VAS).Results:The mean artery pressure(MAP)and heart rate(HR)were lower in the Dexmedetomidine group than in the normal saline group before anesthesia induction(T1), immediately after intubation(T3)and immediately after extubation(T5)( P<0.05). The Ramsay scores were higher and the VAS scores were lower in the Dexmedetomidine group than in the normal saline group at 1 h and 4 h after surgery( P<0.05). The doses of intraoperative propofol and remifentanil were lower in the Dexmedetomidine group than in the normal saline group[(1121.5±198.5)mg vs.(1395.6±332.7)mg, (3.1±0.9)mg vs.(5.5±1.2)mg, P<0.05]. Conclusions:The use of Dexmedetomidine for supplemental anesthesia can effectively maintain the stability of the patient's intraoperative hemodynamics and enhance the sedative and analgesic effects while reducing the amount of anesthetic drugs in patients receiving radical gastric cancer surgery under general anesthesia.

Objective To study the effects of repetitive transcranial magnetic stimulation(rTMS) of the supplementary motor area(SMA)on the cortical excitability in patients with Parkinson's disease(PD).Methods Sixteen patients with PD were included in this study.The motor evoked potentials(MEP)and the N30 component of somatosensory evoked potentials(SEP) were assessed for each patient before and after 1200 pulses of rTMS of the SMA at 5 Hz and an intensity of 100% of relaxed motor threshold (RMT) for the abductor pollicis brevis.Results Ten minutes after the rTMS intervention,the peak-to-peak amplitude of the SEP component P20-N30 increased significantly(P<0.05),with the P/F index decreased simultaneously(P<0.05).The MEP amplitude increased significantly,and reached the highest value at 10min after the rTMS intervention. Conclusion 5 Hz rTMS of the SMA can improve the excitability of the SMA itself temporarily.Meanwhile,it can induce a short-lasting facilitation of the excitability of M1 connected with SMA.

Objective To compare the differences and characteristics of the dose distribution of the two optimization methods in the three dimensional brachytherapy,and provide the basis for clinieal treatment.Methods Excel 2007 was used to generate random number.And a total of 21 patients of cervical cancer were selected from those who have completed the treatment.Inverse simulated annealing optimization (IPSA) plans were designed for graphical optimization (GO) plans.The dose volume histogram (DVH) parameters of the targets (V100％,V150％) and the organs (D1 cm3,D2cm3) of the two methods were analyzed.Results The targets dose of both plans could meet the prescription requirements.There was no statistically significant difference in the dose parameters of all targets (P ＞ 0.05).The closes of D1 cm3 and D2cm3 in the bladder of IPSA plan were significantly lower than that of the GO plan (t =3.596,3.490,P ＜ 0.05).There was no statistically significant difference in the dose parameters of rectum (P ＞ 0.05).Conclusions For cervix brachytherapy,the GO and IPSA have no effect on targets dose,but IPSA optimization can reduce the maximum dose of bladder.

Objective:To evaluate the efficacy and safety of combined cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) with lobaplatin and docetaxel for treatment of synchronous peritoneal carcinomatosis (PC) from gastric cancer. Methods:Fifty patients with synchronous PC from gastric cancer were treated by 52 CRS+HIPEC procedures with 100 mg of lobaplatin and 120 mg of docetaxel in 12000 mL of normal saline at (43 ± 0.5)℃for 60 min. The primary and secondary endpoints were overall survival (OS) and perioperative safety profiles, respectively. Results:At a median follow-up of 22.5 months, the median OS rate was 14.3 (95%CI:7.6-21.0) months, and the 1-, 2-, and 3-year survival rates were 58%, 40%, and 32%, respectively. No perioperative deaths or serious adverse events occurred in 12 cases (23.1%). Multivariate analysis indicated that completeness of cytoreduction, nor-mality of perioperative tumor markers, and adjuvant chemotherapy of more than six cycles were independent predictors for improved survival. Conclusions:CRS+HIPEC with lobaplatin and docetaxel could improve the OS and ensure perioperative safety of patients with synchronous PC from gastric cancer.

Objective To retrospectively analyzed the current application of warfarin in hospitalized patients with non-valvular atrial fibrillationand ( NVAF), explore the key role of clinical pharmacists in warfarin medication. Methods A retrospective survey of anticoagulant therapy for 179 hospitalized patients with non-valvular atrial fibrillation in Renming Hospotal of Wuhan University from January to December 2013 was retrived,including the usage of warfarin for NVAF and new-onset atrial fibrillation,dosage,international normalized ratio(INR),hemorrhage event and so on.The simple factor like the age,complicated chronic diseases and previous cerebrovascular events on the use of warfarin was explored. Results The total response rate to anticoagulants was 85.6% for patients with high risk of stroke(27.3% with warfarin and 58.3% with antiplatelet therapy),who are recommended to use warfarin,patient were treated with anti-thrombotic therapy.The total of 19.1% of the patients with new-onset atrial fibrillation used warfarin as therapy.The whole monitoring rate of INR was 89.8%,and the good control rate was 11.9%. Univariate analysis showed that some high risk factors such as age and high blood pressure affected the usage of warfarin. Conclusion The anti-thrombotic therapy for NVAF patients in the hospital is good,but usage of warfarin for those with new-onset atrial fibrillation is low,which couldn't reach the INR standard. More attention should be taken by the clinic pharmacists in effective managing the use of anticoagulant to build a safe,economic and effective medication system for warfarin application.

Objective To investigate the diagnostic value of anti-mutated citrullinated vimentin (anti-MCV) and anti-cyclic citrullinated peptide (anti-CCP) antibodies for ankylosing spondylitis (AS), and to establish a new diagnostic method of AS based on anti-citrullinated protein/peptide antibodies (ACPAs) detection.Methods Totally 121 AS patients(AS group), 97 rheumatoid arthritis(RA) patients (RA group)and 103 healthy people(control group) were enrolled for the detection of serum levels of anti-MCV and anti-CCP antibodies using ELISA method as a diagnostic test .HLA-B27 in AS patients was tested by flow cytometry , and RF-IgM in RA and AS patients was detected by immune rate nephelometry .Receiver operating characteristics ( ROC) curve was used to analyze the diagnostic value and to determine the cut-off value.Anti-MCV and anti-CCP antibodies among each group were compared by Mann-Whitney U test, Chi-square test or Fisher′s exact test was used to compare positive rate .Results The anti-MCV levels in AS group [11.60 ( 12.36-25.83 ) U/ml ] were significantly higher than control group [ 11.60 ( 8.41 -13.54)U/ml ],U=2 413,P <0.001, while the levels of anti-CCP had no difference between the two groups [AS group 6.22 (4.30 -8.07) U/ml], and control group [6.01 (3.77 -7.58) U/ml], respectively;U=5 421,P=0.094.The calculated area under the ROC curve of anti-MCV was 0.806,and 14.67 U/ml was the optimal cut-off value with sensitivity of 0.645 and specificity of 0.942.In both HLA-B27 positive and negative AS patients , anti-MCV antibodies levels and positive rate were significantly higher than control group using new cut-off value above (U =133.5, P =0.001; U =2 279.5,P <0.001). Sensitivity of the combination detection of anti-MCV and anti-CCP ( MCV+CCP-) or RF-IgM ( MCV+RF-) were 60.3%(73/121), 62.8% (76/121) and specificity were 89.7% (87/97), 90.7% (88/97) respectively in differential diagnosis of AS and RA , which were significantly higher than anti-MCV detection alone in specificity (16.5%,16/97).Conclusions Anti-MCV could be a new biomarker for the diagnosis of AS .With high sensitivity and specificity , anti-MCV has an equal diagnostic efficiency in HLA-B27 positive and negative AS patients using our new cut-off value.Additionally, the combination detection of anti-MCV and anti-CCP or RF-IgM could be an effective method for differential diagnosis of AS and RA .
