Objective:To investigate the application value of thromboelastography (TEG) in choosing antiplatelet drug for patients with cerebral arterial thrombosis.Methods: 100 new patients with cerebral arterial thrombosis, who received single antiplatelet therapy after received dual antiplatelet therapy (aspirin and clopidogrel) in acute stage (14d), were randomly divided into observation group (50cases)and control group (50cases). According to different method of choosing drug, patients of control group randomly were implemented different single antiplatelet drug, while patients of observation group received more sensitive antiplatelet drug based on TEG results. The follow-up observation about recurrent situation of cerebral arterial thrombosis for the two groups were carried out in further study.Results: In one year, the recurrence rate of cerebral arterial thrombosis of observation group (6%, 3/50) was significantly lower than that of control group (20%, 10/50) (x2=4.332,P<0.05). The differences of recurrence rate between different antiplatelet drug in intra-group were not statistically significant.Conclusion: TEG can efficiently evaluate the therapeutic effect of antiplatelet drug, and guide the selection for drug so as to reduce the recurrence rate of cerebral arterial thrombosis.

Aim To study the effect of 2,3,4′,5-tetrahydroxystilbene-2-O-?-D glucoside(TSG) on vascular smooth muscle cells(VSMCs) proliferation induced by fetal bovine serum and explore the underlying mechanisms.Methods VSMCs were cultured from rat aorta using explant technique.VSMCs proliferation was analyzed by 5-bromo-2-deoxyuridine(Brdu) incorporation assay.Cell cycle phase distributions were determined by flow cytometry.The expression of proliferating cell nuclear antigen(PCNA) was evaluated by Western blot analysis.The level of intracellular reactive oxygen species(ROS) was estimated through fluorescence assay.The intracellular activities of superoxide dismutase(SOD),catalase(CAT),and glutathi one peroxidase(GSH-px) were measured using biochemical method.Results TSG in the experimental concentration 0.1～100 ?mol?L~-1 exhibited no apparent cytotoxocity.10 ?mol?L~-1 and 100 ?mol?L~-1 TSG significantly inhibited the proliferation of VSMCs induced by serum,cell cycle transition from G0/G1phase to S phase,PCNA expression in nucleus of VSMCs and level of intracellular ROS.100 ?mol?L~-1 TSG markedly increased the activities of SOD and GSH-px.Conclusions Certain concentration of TSG can prevent VSMCs proliferation effect mediated by serum;the mechanism about TSG effect may be associated with arresting G0/G1 to S progression,decreasing PCNA expression and improving the antioxidation of VSMCs.

Objective:To explore the effects of intraspinal blocking analgesia on the delivery quality and puerperal pelvic floor function of primiparas.Methods:A total of 99 primiparas who delivered in the Second People′s Hospital of Wuhu City from January 2021 to April 2022 were enrolled in this study, 54 patients received intraspinal blocking analgesia (study group) and 45 patients received conventional treatment, without intraspinal blocking analgesia (control group). The delivery quality between the two groups was compared, and the pelvic floor function was evaluated and compared by pelvic floor rehabilitation therapy instrument and pelvic floor ultrasound at 6-8 weeks after delivery.Results:Vaginal delivery were successful in both groups. The total labor duration in the study group was longer than that in the control group: (8.03 ± 2.94) h vs. (6.89 ± 3.49) h, there was statistical difference ( P<0.05). The maximum value of pelvic floor rapid contraction stage, rising time and average value of continuous contraction stage in the study group were higher than those in the control group: (32.85 ± 10.13) μV vs. (14.73 ± 3.25) μV, (0.28 ± 0.06) s vs. (0.22 ± 0.05) s, (30.26 ± 5.24) μV vs. (16.74 ± 4.00) μV, there were statistical differences ( P<0.05). There were no statistical differences in other indicators such as the pre-resting stage, rapid contraction phase recovery time and post-resting stage between the two groups ( P>0.05). The rate of pelvic floor class Ⅰ and class Ⅱ muscle abnormalities at 6-8 weeks after delivery in the study group were lower than those in the control group, but there were no statistical differences ( P>0.05). The maximum Valsalva state hiatus area of levator ani muscle, maximum Valsalva state bladder posterior urethral angle, hiatus area of levator ani muscle at rest state and bladder neck degree in the study group were smaller than those in the control group: (19.09 ± 4.82) cm 2 vs. (23.00 ± 5.34) cm 2, (138.59 ± 23.14)° vs. (148.47 ± 20.38)°, (9.96 ± 2.63) cm 2 vs. (11.60 ± 2.75) cm 2, (20.13 ± 4.37) mm vs. (28.05 ± 6.52) mm, there were statistical differences ( P<0.05). Conclusions:Although intraspinal block analgesia can prolong the total labor time of primipara, but it can reduce the damage of pelvic floor function, possibly by increasing systolic period to protect pelvic floor muscles.

Objective Mitral valve regurgitation often leads to cardiac insufficiency or even heart failure .Methods We tried a mitral valve annuloplasty with a ring to improve the effect of mitral valvuloplasty , 5 males and 6 females; aged(8.0 ± 4.5)years;weight(26.1 ±13.9)kg.From February 2015 to December 2017, 11 children underwent mitral valve annuloplasty with an mitral valve ring in our hospital.Immediately after surgery, the degree of mitral valve regurgitation was significant im-proved from moderate-severe to mild-moderate(P<0.05).Results 1 case of early death, 1 case had a mitral valve replace-ment because of early hemolysis.The rest of the children were discharged smoothly.The follow-up of 3 months of mitral valve regurgitation was not aggravated comparing with that immediately after surgery(P>0.05).There was no worsening of cardiac function at follow-up(P>0.05), and no other adverse events.Therefore, artificial mitral annuloplasty with a ring is effective in treating mitral regurgitation in children .The annulus had potential growth characteristics and did not require lifelong oral an-ticoagulant.Conclusion For some patients with difficulty, this method of mitral valvuloplasty can enlarge the surgical indica-tion and improve the quality of life of children.The treatment effect is good.

Objective:To explore the safety and nosocomial infection control measures of COVID-19 patients of end-stage respiratory failure after lung transplantation.Methods:Lung transplantation was performed for a COVID-19 patient with end-stage respiratory failure after a negative conversion of 2019-nCoV nucleic acid. Before operation, all medical staff received simulated training on nosocomial infection. The procedures were performed in an operation room with a negative pressure environment. The three-grade preventive strategy was implemented and wearing positive pressure protective mask of electric air supply required. During operation, the patient was managed according to the in-hospital protection process. The environment and medical instruments were disinfected after operation.Results:The operation was completed successfully. The 2019-nCoV nucleic acid test was negative for many times after operation. Participants were placed in medical isolation for 14 days after surgery. During the period, nucleic acid test was negative twice.Conclusions:As an exploratory treatment, lung transplantation is a safe option for end-stage respiratory failure in COVID-19 in operation room with a negative pressure environment and implementations of three-grade preventive strategy.

Objective:To investigate the application value of three-dimensional visualization technology in management of middle hepatic vein (MHV) processing in associating liver partition and portal vein ligation for staged hepatectomy(ALPPS).Methods:The retrospective and descriptive study was conducted. The clinical data of 40 patients with right massive liver cancer or multiple right liver lesions who underwent ALPPS in the First Affiliated Hospital of Guangxi Medical University from November 2017 to August 2019 were collected. There were 34 males and 6 females, aged (44±9)years, with a range from 26 to 64 years. All patients underwent multi-slice computed tomography (CT) plain and enhanced scan of superior abdominal region before operation, and the data were transmitted to the liver visualization analysis software IQQA system with 1.5 mm thin-layer images to complete the three-dimensional reconstruction of the liver and its blood vessels. Patients were performed ALPPS based on results of three-dimensional reconstruction and intraoperative findings. Observation indicators: (1) results of preoperative three-dimensional reconstruction; (2) surgical situations; (3) follow-up. Follow-up was conducted using outpatient examinations and telephone interview to detect postopeartive survival of patients up to March 2020. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were described as M (range). Count data were represented as absolute numbers. Results:(1) Results of preoperative three-dimensional reconstruction: 40 patients underwent three-dimensional reconstruction successfully, of which 37 clearly showed MHV, tumor location and relationship between them, 3 patients showed unclearly MHV and were classified based on two-dimensional images. Of the 40 patients, 12 had MHV classified as type A, 13 as type B, 9 as type C, and 6 as type D. Three-dimensional reconstruction of vessels showed 22 with umbilical veins and 9 with anterior veins. Of the 40 patients, 35 were predicted to preserve MHV, and 5 were predicted to resect MHV. Total estimated liver volume, tumor volume, and reserved liver volume were (1 012±119)cm 3, 600 cm 3(8-2 055 cm 3), (346±80)cm 3. The ratio of future liver remnant to standard liver volume was 34%±8%. (2) Surgical situations : 40 patients underwent the first-stage ALPPS, including 35 with preservation of MHV and 5 with resection of MHV, which was accorded with preoperative prediction. Thirty-four patients underwent the second-stage ALPPS, and 6 patients had failure to receive the second-stage ALPPS due to undificiency future liver remnant. The operation time and volume of intraoperative blood loss for 40 patients undergoing first-stage ALPPS were (350±79)minutes and 300 mL(range, 100-2 600 mL). Three patients received blood transfusion and no perioperative death occurred. There were 24 patients with grade A heptic insufficiency according to criteria of International StudyGroup of Liver Surgery (ISGLS) and 16 patients with grade B heptic insufficiency after the first-stage ALPPS. Twenty-eight patients had grade Ⅰ complications of Clavien-Dindo classification, including 17 with a small pleural effusion, 10 with a small pleural and abdominal effusion, 1 with hypoproteinemia; 8 patients had grade Ⅱ complications of Clavien-Dindo classification, including 5 with pneumonia, 1 with pneumonia combined with pleural and abdominal effusion, 1 with coagulation disorders, 1 with biliary fistula; 3 patients had grade Ⅲ complications of Clavien-Dindo classification, including 2 with pneumothorax and pneumonia, 1 with pneumothorax, pneumonia and coagulation disorders; 1 patient had grade Ⅳ complications of Clavien-Dindo classification as systemic inflammatory response syndrome. All patients with complications were improved after symptomatic treatment, anti infection, transfusion of fresh frozen plasma or drainage. For the 34 patients undergoing the second-stage ALPPS, the operation time and volume of intraoperative blood loss were (320±83)minutes and 500 mL(range, 200-6 000 mL). Twelve patients received blood transfusion. There were 12 patients with grade A heptic insufficiency according to criteria of ISGLS and 22 with grade B heptic insufficiency after the second-stage ALPPS. Eighteen patients had grade Ⅰ complications of Clavien-Dindo classification, including 11 with a small pleural effusion, 7 with a small pleural and abdominal effusion; 12 patients had grade Ⅱ complications of Clavien-Dindo classification, including 4 with pneumonia, 4 with coagulation disorders, 3 with massive abdominal effusion, 1 with biliary fistula; 3 patients had grade Ⅲ complications of Clavien-Dindo classification, including 1 with pneumothorax and pneumonia, 1 with massive pleural effusion, 1 with obstructive jaundice; 1 patient had grade Ⅳ complications of Clavien-Dindo classification as pneumonia and anemia. All patients with complications were improved after symptomatic treatment, anti infection, transfusion of fresh frozen plasma or drainage. (3) Follow-up: 40 patients were followed up for 2-35 months, with a median follow-up time of 17 months. The 6-month, 1-, and 2-year survival cases were 35, 26, 21 cases. Conclusion:Three-dimensional visualization technology can clearly show the MHV classification and its relationship with tumor location, which has an important guiding significance in the decision-making of MHV management in ALPPS.

Objective    To explore the early results of Ozaki operation in children with aortic regurgitation. Methods    We retrospectively analyzed the clinical data of 15 patients with aortic regurgitation who received the Ozaki operation in our hospital from April 2017 to July 2019. There were 11 males and 4 females with an average operation age of 10.7±3.7 years. Besides preoperative evaluation, aortic regurgitation and cardiac function were evaluated on 1 day, 1 week, 1 month, 3 months, and 6-12 months after surgery. Results    In 14 (93.3%) patients , the aortic valve leaflets functioned well on 1 day, 1 month, 3 months, and 6-12 months, and the regurgitation grade was Ⅰ-Ⅱ, which was improved than before (P=0.001). The cardiac function of children recovered quickly after operation. There was no statistical difference in ejection fraction on 1 day, 1 month, 3 months, and 6-12 months after operation (P>0.05). No children died, and no other clinical event was found. Conclusion    The Ozaki technique of reconstructing a tricuspid aortic valve leaflet for the treatment of severe aortic regurgitation in children is effective in short term, and the persistence of its valve function remains to be determined in the long-term follow-up.
