ABSTRACT

Background@#Xylazole (Xyl) is a veterinary anesthetic that is structurally and functionally similar to xylazine. However, the effects of Xyl in vitro remain unknown. @*Objectives@#This study aimed to investigate the anesthetic mechanism of Xyl using fetal rat nerve cells treated with Xyl. @*Methods@#Fetal rat nerve cells cultured for seven days were treated with 10, 20, 30, and 40 μg/ mL Xyl for 0, 5, 10, 15, 20, 25, 30, 45, 60, 90, and 120 min. Variations of amino acid neurotransmitters (AANTs), Nitric oxide-Cyclic GMP (NO-cGMP) signaling pathway, and ATPase were evaluated. @*Results@#Xyl decreased the levels of cGMP and NO in nerve cells. Furthermore, Xyl affected the AANT content and Na+ -K+ -ATPase and Ca2+ -Mg2+ -ATPase activity in nerve cells. These findings suggested that Xyl inhibited the NO-cGMP signaling pathway in nerve cells in vitro. @*Conclusions@#This study provided new evidence that the anesthetic and analgesic effects of Xyl are related to the inhibition of the NO-cGMP signaling pathway.

ABSTRACT

Cancer is a complex disease associated with multiple gene mutations and malignant phenotypes, and multi-target drugs provide a promising therapy idea for the treatment of cancer. Natural products with abundant chemical structure types and rich pharmacological characteristics could be ideal sources for screening multi-target antineoplastic drugs. In this paper, 50 tumor-related targets were collected by searching the Therapeutic Target Database and Thomson Reuters Integrity database, and a multi-target anti-cancer prediction system based on mt-QSAR models was constructed by using naïve Bayesian and recursive partitioning algorithm for the first time. Through the multi-target anti-cancer prediction system, some dominant fragments that act on multiple tumor-related targets were analyzed, which could be helpful in designing multi-target anti-cancer drugs. Anti-cancer traditional Chinese medicine (TCM) and its natural products were collected to form a TCM formula-based natural products library, and the potential targets of the natural products in the library were predicted by multi-target anti-cancer prediction system. As a result, alkaloids, flavonoids and terpenoids were predicted to act on multiple tumor-related targets. The predicted targets of some representative compounds were verified according to literature review and most of the selected natural compounds were found to exert certain anti-cancer activity in vitro biological experiments. In conclusion, the multi-target anti-cancer prediction system is very effective and reliable, and it could be further used for elucidating the functional mechanism of anti-cancer TCM formula and screening for multi-target anti-cancer drugs. The anti-cancer natural compounds found in this paper will lay important information for further study.

ABSTRACT

OBJECTIVE@#To evaluate the clinical effect of haploid allogeneic hematopoietic stem cell transplantation(haplo-HSCT) in the treatment of severe aplastic anemia (SAA), and to explore the efficacy different between post-transplant cyclophosphamide (PT/Cy) and standard-dose ATG.@*METHODS@#The clinical data of 38 patients with SAA in our hospital from January 2012 to December 2019 were collected and retrospectively analyzed. The efficacy was evaluated. The patients with haplo-HSCT were divided into low-dose ATG combined with PT/Cy group and standard-dose ATG group, and the blood cell hematopoietic reconstruction time, GVHD incidence, mortality and survival time of the patients in the two groups was compared.@*RESULTS@#Among the 32 patients, hematopoietic reconstitution were detected in 9375%(30/32) recipients. The median time of neutrophil and platelet engraftment was 15(10-22) days and 13(7-30) days, respectively. The incidence of GVHD was 21.89%, the incidence of infection was 93.75%, and the 2-year overall survival rate was 84.38%. The hematopoietic reconstitution time, incidence of GVHD, mortality rate and survival time were no statistical differences between the patients in the two groups(all P>0.05).@*CONCLUSION@#Haplo-HSCT is an effective method for the treatment of SAA,low-dose ATG combined with PT/Cy can lighten the economic burden on patients, it would be a feasible treatment plan for SAA with light side effect.

ABSTRACT

OBJECTIVES@#To explore the optimal maintenance dose of caffeine citrate for preterm infants requiring assisted ventilation and caffeine citrate treatment.@*METHODS@#A retrospective analysis was performed on the medical data of 566 preterm infants (gestational age ≤34 weeks) who were treated and required assisted ventilation and caffeine citrate treatment in the neonatal intensive care unit of 30 tertiary hospitals in Jiangsu Province of China between January 1 and December 31, 2019. The 405 preterm infants receiving high-dose (10 mg/kg per day) caffeine citrate after a loading dose of 20 mg/kg within 24 hours after birth were enrolled as the high-dose group. The 161 preterm infants receiving low-dose (5 mg/kg per day) caffeine citrate were enrolled as the low-dose group.@*RESULTS@#Compared with the low-dose group, the high-dose group had significant reductions in the need for high-concentration oxygen during assisted ventilation (P=0.044), the duration of oxygen inhalation after weaning from noninvasive ventilation (P<0.01), total oxygen inhalation time during hospitalization (P<0.01), the proportion of preterm infants requiring noninvasive ventilation again (P<0.01), the rate of use of pulmonary surfactant and budesonide (P<0.05), and the incidence rates of apnea and bronchopulmonary dysplasia (P<0.01), but the high-dose group had a significantly increased incidence rate of feeding intolerance (P=0.032). There were no significant differences between the two groups in the body weight change, the incidence rates of retinopathy of prematurity, intraventricular hemorrhage or necrotizing enterocolitis, the mortality rate, and the duration of caffeine use (P>0.05).@*CONCLUSIONS@#This pilot multicenter study shows that the high maintenance dose (10 mg/kg per day) is generally beneficial to preterm infants in China and does not increase the incidence rate of common adverse reactions. For the risk of feeding intolerance, further research is needed to eliminate the interference of confounding factors as far as possible.

ABSTRACT

OBJECTIVE@#To investigate the accuracy and safety of pedicle screw placement assisted by orthopedic robot and C-arm fluoroscopy.@*METHODS@#The clinical data of 36 patients with spinal diseases underwent surgical treatment from January 2019 to August 2020 was retrospectively analyzed. Among them, 18 cases were implanted pedicle screws assisted by orthopaedic robot(observation group), including 12 males and 6 females, aged from 16 to 61 years with an average of (38.44±3.60) years;there were 1 case of adolescent scoliosis, 1 case of spinal tuberculosis, 7 cases of lumbar spondylolisthesis, 4 cases of thoracic fracture and 5 cases of lumbar fracture. Another 18 cases were implanted pedicle screws assisted by C-arm fluoroscopy(control group), including 10 males and 8 females, aged from 18 to 58 years with an average of (43.22±2.53) years;there were 1 case of adolescent scoliosis, 6 cases of lumbar spondylolisthesis, 6 cases of thoracic fracture and 5 cases of lumbar fracture. The intraoperative fluoroscopy times, nail placement time and postoperative complications were recorded in two groups. CT scan was performed after operation. The Gertzbein-Robbins standard was used to evaluate the accuracy of pedicle screw placement which was calculated.@*RESULTS@#The number of intraoperative fluoroscopy in observation group was(6.89±0.20) times, which was significantly higher than that in control group(14.00±0.18)times(P<0.05). The placement time of each screw in observation group was(2.56±0.12) min, which was significantly different from that in control group(4.22±0.17) min (P<0.05). One case of incision infection occurred in control group after operation, and recovered after active dressing change. During the follow-up period, no serious complications such as screw loosening and fracture occurred in two groups, and there was no significant difference in complications between two groups(P>0.05). A total of 107 screws were placed in observation group, including 101 screws in class A, 4 in class B, 2 in class C, 0 in class D and 0 in class E, the accuracy rate of pedicle screw placement=[(number of screws in class A+B) / the number of all screws placed in the group] ×100%=98.1%(105/107); and a total of 104 screws were placed in control group, including 90 screws in class A, 4 in class B, 5 in class C, 5 in class D and 0 in class E, the accuracy rate of pedicle screw implantation=[(number of screws in class A+B/the number of all screws placed in the group]×100%=90.3% (94/104); there was significant difference between two groups (P<0.05).@*CONCLUSION@#Orthopaedic robot assisted pedicle screw placement has the advantages of less fluoroscopy times, shorter screw placement time and higher accuracy, which can further improve the surgical safety and has a broad application prospect in the orthopaedic.

ABSTRACT

OBJECTIVE@#To compare the clinical effect of SUN 's abdominal acupuncture and conventional acupuncture in the treatment of depression after methamphetamine withdrawal.@*METHODS@#A total of 80 female patients with depression after methamphetamine withdrawal were randomly divided into an observation group (40 cases, 1 case dropped off) and a control group (40 cases, 2 cases dropped off). The control group was treated with conventional acupuncture at Baihui (GV 20), Yintang (GV 29), Taichong (LR 3), Shenmen (HT 7), Neiguan (PC 6), Danzhong (GV 17), and the observation group was treated with SUN 's abdominal acupuncture at area 1 of the abdomen and area 8 of the abdomen. Both groups were treated once a day, 30 min each time, 6 days as a course of treatment, 1 day rest between treatment courses, a total of 4 courses of treatment. The scores of withdrawal symptoms, Hamilton depression scale (HAMD), Pittsburgh sleep quality index (PSQI) scale and serum serotonin (5-HT) level were compared between the two groups before and after treatment.@*RESULTS@#After treatment, the scores of withdrawal symptoms, HAMD and the various scores and total score of PSQI scale in the two groups were all lower than before treatment (P<0.01), and the scores of withdrawal symptoms, HAMD and the sleep quality, time to fall asleep, sleep time scores and total score of PSQI in the observation group were lower than the control group (P<0.05, P<0.01). After treatment, the serum 5-HT level of the two groups was increased (P<0.01), and that in the observation group was higher than the control group (P<0.05).@*CONCLUSION@#SUN 's abdominal acupuncture can improve withdrawal symptom, depression and sleep quality, increase serum 5-HT content in treatment of depression after methamphetamine withdrawal, and has better effect than conventional acupuncture.

ABSTRACT

@#Objective    To compare the surgical effects of total endoscopy and right thoracic small-incision for atrial septal defect repair. Methods    The clinical data of 60 patients undergoing atrial septal defect repair in our hospital in 2019 under cardiopulmonary bypass (CPB) were collected. The patients were divided into two groups according to different surgical methods: a right thoracic small-incision group (n=31), including 11 males and 20 females, aged 44.5±11.5 years; a thoracoscopic surgery group (n=29), including 12 males and 17 females, aged 46.5±12.7 years. The clinical data were compared between the two groups. Results    The baseline data of the patients were not statistically different (P>0.05). The surgeries were successfully completed in the two groups of patients. The volume of chest drainage in 24 h after the surgery (59.1±43.9 mL vs. 91.0±72.9 mL, P=0.046), red blood cell input (78.0±63.9 mL vs. 121.0±88.7 mL, P=0.036), length of postoperative hospital stay (5.5±2.1 d vs. 7.2±2.1 d, P=0.003), postoperative complications rate (6.9%vs. 22.6%, P=0.029) in the thoracoscopic surgery group were significantly better than those in the right thoracic small-incision group. There was no significant difference in the CPB time, aorta blocking time, operation time, mechanical ventilation time, ICU retention time or postoperative pain score between the two groups (P>0.05). Conclusion    The two techniques are safe and effective. Patients undergoing thoracoscopic repair of atrial septal defect have small trauma, short postoperative hospital stay, mild pain, beautiful incision, and no bone damage, which is worthy of clinical promotion.

ABSTRACT

A patient was pregnant four months after the percutaneous coronary intervention, and the ultrasound indicated a complete placenta previa and a placenta percreta. Concerned about radiation and drugs exposure on the fetus, the patient chose to terminate the pregnancy. After multidisciplinary consultation, tirofiban was used for antithrombotic therapy in substitution for dual antiplatelet drugs, and an abdominal aortic balloon was inserted preoperatively. The placenta that penetrated the serous membrane and uterine wall at laparotomy was resected, and the uterus was reconstructed. Prophylactic antibiotics, anticoagulation, and transitional antiplatelet therapy with tirofiban were given after the operation. The patient was discharged on day six postoperatively.

ABSTRACT

Objective:To evaluate the value of 68Ga-1, 4, 7, 10-tetraazacyclododecane-1, 4, 7, 10-tetraacetic acid (DOTA)-fibroblast activating protein inhibitor (FAPI)-04 PET/CT on assessing different pathological grades in patients with renal fibrosis. Methods:A total of 25 patients (11 males, 14 females; age (39.3±13.9) years) diagnosed with renal fibrosis in the Affiliated Hospital of Southwest Medical University from September 2020 to August 2021 were retrospectively analyzed. All patients underwent renal puncture examination and 68Ga-DOTA-FAPI-04 PET/CT examination. The pathological results of kidney puncture were as the " gold standard" to divide the patients into mild fibrosis (Ⅰ), moderate fibrosis (Ⅱ), and severe fibrosis (Ⅲ). At the same time, 20 patients (10 males, 10 females; age (47.5±13.2) years) who underwent 68Ga-DOTA-FAPI-04 PET/CT examination showed no abnormal uptake of radioactivity in bilateral kidneys and no history of urinary system related diseases were enrolled as normal controls. Parameters including the maximum standardized uptake value (SUV max) of both kidneys, the mean standardized uptake value (SUV mean) of the liver, target/background ratio (TBR), glomerular filtration rate (GFR), and serum creatinine (Scr) were collected. Kruskal-Wallis rank sum test and Bonferroni correction method were used to compare the differences of SUV max, SUV mean, TBR and Scr among groups. One-way analysis of variance and least significant difference (LSD) t test were used to compare the difference of GFR among groups. The receiver operating characteristic (ROC) curve analysis was used to analyze the diagnostic efficacy of SUV max for the degree of renal fibrosis. Results:Of 25 patients, 22 had increased imaging agent uptake and the sensitivity of 68Ga-DOTA-FAPI-04 PET/CT in diagnosing renal fibrosis was 88%. The SUV max and TBR of patients with fibrosis grade Ⅰ, Ⅱ and Ⅲ were significantly higher than those of controls (SUV max: 4.40(3.30, 4.50), 5.90(4.28, 6.48), 8.50(7.50, 9.73) and 1.44(1.38, 1.68); TBR: 6.340±2.389, 8.097±1.420, 11.343±2.002 and 2.986±0.645; H values: 33.685, 32.368, all adjusted P<0.05 (Bonferroni correction method)). The Scr of patients with fibrosis grade Ⅰ and Ⅲ were significantly different (70.1(55.4, 92.5) and 174.1(161.4, 498.2) μmol/L; H=9.770, adjusted P<0.05 (Bonferroni correction method)). The liver SUV mean of patients with renal fibrosis grades Ⅱ and Ⅲ were significantly higher than that of controls (0.673±0.129, 0.751±0.170 and 0.514±0.142; H=15.609, both adjusted P<0.05 (Bonferroni correction method)). The GFR of patients with fibrosis grade Ⅲ had significant differences with grade Ⅰ and Ⅱ ((27.867±15.747), (87.756±31.657) and (63.160±29.556) ml/min; F=8.298, both P<0.05). ROC curve analysis showed that the area under curve was 0.946 7 (95% CI: 0.899 6-0.993 8, P<0.001). Conclusion:68Ga-DOTA-FAPI-04 PET/CT has a certain value in evaluating the degree of renal fibrosis, which can be used as a supplementary examination method for diagnosing renal fibrosis.

ABSTRACT

Objective:To observe the pattern change of chemokine (C-X-C motif) ligand 12 (CXCL12)/C-X-C chemokine receptor type 4 (CXCR4) in systemic lupus erythematosus (SLE) by comparing the condition of SLE patients between pre-treatment and post-treatment.Methods:Peripheral blood mononuclear cells were obtained from 15 healthy controls and 8 first visit SLE patients before and after treatment. The expression of CXCR4, CD3, and CD19 on lymphocytes were detected by flow cytometry. CXCL12 concentration in serum was measured by enzyme-linked immunosorbent assay. For statistical analysis, the independent sample t test was used for independent samples of normally distributed data, the paired sample t test was used for paired samples of normally distributed data, the Mann-Whitney U test was used for independent samples of nonnormal distribution data, and the Wilcoxon test was used for comparison of related samples of non-normal distribution data. In the correlation analysis, Pearson correlation coefficient was used for data conforming to the normal distribution, and Spearman correlation coefficient was used for data not conforming to the normal distribution. Results:① The percentage of CXCR4 + lymphocyte subsets was significantly increased after treatment (90±7)% when compared with that before treatment (75±17)% ( t=-2.440, P<0.05). ② The mean fluorescence intensity of CXCR4 + lymphocyte subsets was significantly decreased after treatment [119.00(92.93, 142.50)] compared with that before treatment [177.00(130.75, 280.25)] ( Z=-2.100, P<0.05). ③ The plasma concentration of CXCL12 was significantly decreased after treatment (540±243) pg/ml when compared with that before the treatment (1 146±570) pg/ml ( t=3.219, P<0.05). ④ Moreover, there were significant correlations between the trends of the above three indicators after treatment. Conclusion:The proportion, the mean fluorescence intensity of CXCR4 + lymphocyte in peripheal blood subsets and the concentration of CXCL12 in plasma of first visit SLE patients are significantly changed after treatment. That suggests CXCL12/CXCR4 is closely associated with SLE.

ABSTRACT

Objective:To explore the application of four-dimensional automatic left atrial quantitation (4D LAQ) in evaluating left atrial function in patients with essential hypertension (EH) and to find the independent correlative factors affecting left atrial function.Methods:Fifty patients with EH(EH group) and fifty healthy controls(control group) were selected from Fuwai Center China Cardiovascular Hospital from September 2020 to January 2021. Conventional two-dimensional echocardiography was performed, and 4D LAQ parameters, including left atrial minimum volume (LAVmin), left atrial maximum volume (LAVmax), left atrial pre-systolic volume (LAVpreA), left atrial maximum volume index (LAVImax), left atrial reservoir longitudinal strain (LASr), left atrial conduit longitudinal strain (LAScd) and left atrial contraction longitudinal strain (LASct) was analyzed. The independent sample t-test or rank sum test was used to compare the EH group with the normal control group, and ROC curves were used to find the most sensitive parameters for evaluating left atrial function and their correlations were investigated by univariate and multivariate linear regression analyses. Results:Compared with the control group, there was no difference in left ventricular ejection fraction (LVEF) ( P>0.05), LAVmin, LAVmax, LAVpreA and LAVImax increased significantly (all P<0.05), the absolute values of LASr, LAScd and LASct were decreased (all P<0.05). ROC curve analysis showed that LASr had the best performance in evaluating left atrial function in EH patients (AUC: 0.929), systolic blood pressure (SBP), relative wall thickness (RWT) and E/e′ were negatively correlated with LASr (β=-0.308, P<0.05; β=-0.219, P<0.05; β=-0.359, P<0.05). Conclusions:4D LAQ can early identify the changes of left atrial function in EH patients, and the longitudinal strain in the left atrial reservoir period, left atrial conduit period and left atrial contraction period are all impaired in EH patients. LASr has the highest evaluation efficiency in evaluating the left atrial function, and SBP, RWT and E/e′ are independently correlated with LASr.

ABSTRACT

Parthenogenetic embryos, created by activation and diploidization of oocytes, arrest at mid-gestation for defective paternal imprints, which impair placental development. Also, viable offspring has not been obtained without genetic manipulation from parthenogenetic embryonic stem cells (pESCs) derived from parthenogenetic embryos, presumably attributable to their aberrant imprinting. We show that an unlimited number of oocytes can be derived from pESCs and produce healthy offspring. Moreover, normal expression of imprinted genes is found in the germ cells and the mice. pESCs exhibited imprinting consistent with exclusively maternal lineage, and higher X-chromosome activation compared to female ESCs derived from the same mouse genetic background. pESCs differentiated into primordial germ cell-like cells (PGCLCs) and formed oocytes following in vivo transplantation into kidney capsule that produced fertile pups and reconstituted ovarian endocrine function. The transcriptome and methylation of imprinted and X-linked genes in pESC-PGCLCs closely resembled those of in vivo produced PGCs, consistent with efficient reprogramming of methylation and genomic imprinting. These results demonstrate that amplification of germ cells through parthenogenesis faithfully maintains maternal imprinting, offering a promising route for deriving functional oocytes and having potential in rebuilding ovarian endocrine function.

ABSTRACT

OBJECTIVE@#To analyze the risk factors affecting prognosis of children with hemophagocytic lymphohistiocytosis (HLH).@*METHODS@#The clinical manifestations and laboratory data of 143 HLH children who met the HLH-2004 diagnostic criteria in Shenzhen Children's Hospital from January 2009 to May 2017 were retrospectively analyzed, and the independent factors affecting prognosis were also analyzed.@*RESULTS@#The median age of 143 HLH children was 1.9 (0.1-14.3) years old, and the median follow-up time was 6.7 years (1 day - 11.9 years). The overall survival rate of 1 month, 1 year, and 10 years was (87.4±5.5)%, (81.1±6.5)%, and (81.1±6.5)%, respectively. The deaths occurred within 1 year after onset. Multivariate analysis showed that central nervous system (CNS) involvement (P=0.047), low hemoglobin (P=0.002), prolonged activated partial thromboplastin time (APTT) (P<0.001), high triglyceride (P=0.005) were all the independent risk factors affecting survival of the children. Receiver operating characteristic curve indicated that APTT (AUC=0.753, P<0.001) was more valuable than other risk factors in predicting death of the children. The cut-off value of APTT was 56.6 s, and the sensitivity and specificity of which was 55.6% and 89.7%, respectively.@*CONCLUSION@#Hypohemoglobinemia, prolonged APTT, hypertriglyceridemia, and CNS involvement the risk factors affecting prognosis of HLH, and prolonged APTT shows a strong predictive value for death.

ABSTRACT

Objective@#To analyze the possible responses of parents of young children to Child sexual assault (CSA) and the potential influencing factors, so as to provide evidence for prevention programs of CSA.@*Methods@#Part of the data from "2016-2020 Child Injury Prevention Project" was used to analyze responses to CSA among parents of children younger than 3rd grade in primary school by chi square test and Logistic regression analysis.@*Results@#A total of 4 072 parents were included in the analysis. Among them, 86.8% of parents chose "to solve problems together", 51.0% of parents taking children to a "psychologist", 4.9% of parents "scolding children for being too careless", 2.9% of parents "letting child not disclose abuse" and 6.5% of parents chose "other" coping methods. Parents with foreign nationality [OR(95%CI)=2.58(1.25-5.15)] and lower education level (OR=0.26-0.64) tend to "blame" their children. Mothers [(OR(95%CI)=0.54(0.33-0.90)], higher parental education level (OR=0.27-0.72) were more reluctant to encourage their children to keep quiet. Mothers [OR(95%CI)=1.73(1.32-2.27)], older children (OR=1.33-1.78) and parents with higher education level (OR=1.65-2.99) tend to "accompany". Parents aged 30 or more, and from high school/technical school/technical secondary school tend to take their children to see a "psychologist" [OR(95%CI)=1.39(1.14-1.71), 1.79(1.26-2.53)].@*Conclusion@#Parents universally pay attention to the physical and mental health of children after CSA, but some parents still take negative coping methods, e.g. "blame" and "not disclose". Parenting educational level, duration of parent-child communication and age of children are primary factors associated with parental responses to child sexual assault. This study suggests that prevention secondary injury following child sexual assault should be farther strengthened, while fully considering the characteristics of the educated objects.

ABSTRACT

@#Objective    To compare the short-term and long-term effects of minimally invasive esophagectomy (MIE) and traditional open esophagectomy (OE) in patients with stage T1b esophageal squamous cell carcinoma (ESCC). Methods    We retrospectively analyzed the clinical pathology data of 162 patients undergoing thoracic surgery at Northern Jiangsu People's Hospital from 2015 to 2018 whose pathological diagnosis was stage pT1b ESCC. According to the surgical approach, they were divided into MIE group and OE group. There were 55 males and 21 females in the OE group, with an average age of 63.3±5.6 years, and 60 males and 26 females in the MIE group, with an average age of 64.7±6.1 years. The preoperative, intraoperative and postoperative data of the two groups were compared and followed up. Survival data were compared using Kaplan-Meier and log-rank tests between the two groups, and Cox proportional hazard regression models were used to analyze prognostic factors. Results    Compared with the OE group, the intraoperative bleeding volume of the MIE group was less (119.8±70.0 mL vs. 210.5±136.2 mL, P<0.001), and the lymph nodes dissected during the operation were more (19.1±7.4 vs. 13.8±5.9, P<0.001), the rate of postoperative pulmonary infections was lower (9.3% vs. 21.1%, P=0.036), but the operation time was longer (240.0±52.4 min vs. 179.5±35.7 min, P<0.001). Twenty-one patients had lymph node metastasis, and the lymph node metastasis rate was 13.0%. At the end of the follow-up, 19 patients died, and the overall survival (OS) at 1 year, 3 years, and 5 years after operation were 97.5%, 88.8% and 82.9%, respectively; 31 patients had recurrence and metastasis, and the disease-free survival (DFS) rate at 1 year, 3 years, and 5 years after operation was 95.1%, 80.9% and 75.6%. There was no significant difference in OS and DFS between the two groups. Multivariate Cox regression analysis of OS found that lymph node metastasis, anastomotic fistula and chylothorax were independent risk factors for OS. Multivariate Cox regression analysis of DFS found that lymph node metastasis, anastomotic fistula, chylothorax, and vascular cancer thrombus were independent risk factors for OS. Conclusion    MIE can achieve the same long-term effects as OE, with less intraoperative bleeding, more lymph nodes dissected, and lower incidence of postoperative pulmonary infections, but it takes longer operation time.

ABSTRACT

OBJECTIVE@#To explore the surgical method and safety of modified one stage posterior approach total en block spondylectomy combined with pedicle screw fixation and titanium mesh reconstruction for the treatment of invasive thoracic vascular tumor.@*METHODS@#The clinical data of 12 patients with invasive thoracic vasculay tumor from December 2012 to May 2015 was retrospectively analyzed. There were 8 males and 4 females, aged from 40 to 62 years with an average of 51.2 years, the course of disease was 2 months to 8 years with an average of 3.4 years. The lesions involved vertebral bodies:1 case of T@*RESULTS@#All the operations were successful. The average operation time, intraoperative blood loss and blood transfusion were 5.5 h (4.5 to 6.0 h), 1 850 ml (1 650 to 2 500 ml), 1 050 ml (600 to 1 500 ml), respectively. All 12 patients were followed up for 5 months to 2.5 years with an average of 21 months. Local pain and lower limb muscle strength were improved to varying, and the nerve compression symptoms disappeared. The JOA score at 6 months after operation was 12.0±3.4, which was statistically significant difference compared with the preoperative 8.0±2.7 (@*CONCLUSION@#Modified one stage posterior approach total en block spondylectomy is an ideal surgical method for the treatment of invasive thoracic vascular tumors, which has a safe, reliable and long lasting efficacy.

ABSTRACT

OBJECTIVE:To provide reference for the related research and policy-making of drug network transaction governance model. METHODS :Based on the highly chimerism of agile governance concept and drug network transaction ,the governance dilemma of the existing drug network transaction mode were analyzed ,and the optimization path was refined from the perspectives of governance objectives ,tools and subjects. RESULTS & CONCLUSIONS :The unique complexity and innovation of drug network transactions had brought many challenges to the regulatory authorities ,which not only manifested that it was difficult to choose governance objectives and governance tools ,but also manifested that the addition of multiple subjects had broken the traditional single supervision mode. In order to further optimize the governance of drug network transactions ,it is necessary to adhere to the concept of agile governance ,intervene in the market with a more positive attitude ,and pursue the balance between safety and efficiency ;respond to risks with more flexible tools ,and achieve the unity of inclusiveness and prudence ;participate in governance with more diversified subjects ,and form a pattern of joint efforts of government ,enterprises and society.

ABSTRACT

@#The epithelial ingrowth under corneal flap is one of the complications after keratorefractive surgery, of which the incidence has declined dramatically with the improvement of relevant facilities and surgical techniques. However, epithelial ingrowth results from traumatic flap displacement has been describing in the literatures from time to time. If the prompt and efficient treatment cannot be taken, the severe complications of epithelial ingrowth will occur such as the alternation of refraction and cornea keratolysis. In this article, we reviewed the research progress of epithelial ingrowth after keratorefractive surgery.
