ABSTRACT

Objective:To review the outcome of intravitreous anti-vascular endothelial growth factor (VEGF) treatment in patients with X-linked retinoschisis (XLRS) complicated with vitreous hemorrhage (VH).Methods:A retrospective clinical study. From March 1, 2016 to April 1, 2022, 18 patients (19 eyes) diagnosed with XLRS complicated with vitreous hemorrhage in Beijing Tongren Hospital, Capital Medical University of Eye Center were included. All the patients were male, with a median age of 7.05±3.8 years. Best corrected visual acuity (BCVA) and wide-angle fundus photography were performed in all the patients. BCVA was carried out using international standard visual acuity chart, and converted into logarithm of minimum resolution angle (logMAR) in statistics analysis. According to whether the patients received intravitreal injection of ranibizumab (IVR), the patients were divided into injection group and observation group, with 11 eyes in 10 cases and 8 eyes in 8 cases, respectively. In the injection group, 0.025 ml of 10 mg/ml ranibizumab (including 0.25 mg of ranibizumab) was injected into the vitreous cavity of the affected eye. Follow-up time after treatment was 24.82±20.77 months. The VH absorption time, visual acuity changes and complications were observed in the injection group after treatment. Paired sample t test was used to compare BCVA before and after VH and IVR treatment. Independent sample t test was used to compare the VH absorption time between the injection group and the observation group. Results:LogMAR BCVA before and after VH were 0.73±0.32 and 1.80±0.77, respectively. BCVA decreased significantly after VH ( t=-3.620, P=0.006). LogMAR BCVA after VH and IVR were 1.87±0.55 and 0.62±0.29, respectively. BCVA was significantly improved after IVR treatment ( t=6.684, P<0.001). BCVA records were available in 5 eyes before and after IVR, and the BCVA values after VH and IVR were 0.58±0.31 and 0.48±0.20, respectively, with no statistically significant difference ( t=1.000, P=0.374). BCVA increased in 1 eye and remained unchanged in 4 eyes after treatment. BCVA records were available in 5 eyes before VH and after VH absorption in the 8 eyes of the observation group. LogMAR BCVA before VH and after VH absorption were 0.88±0.28 and 0.90±0.26, respectively, with no significant difference ( t=-1.000, P=0.374). After VH absorption, BCVA remained unchanged in 4 eyes and decreased in 1 eye. The absorption time of VH in the injection group and the observation group were 1.80±1.06 and 7.25±5.04 months, respectively. The absorption time of VH was significantly shorter in the injection group than in the observation group, the difference was statistically significant ( t=-3.005, P=0.018). Multivariate linear regression analysis showed that IVR treatment was significantly correlated with VH absorption time ( B=-6.66, 95% confidence interval -10.93--2.39, t=-3.40, P=0.005). In the injection group, VH recurrence occurred in 1 eye after IVR treatment. Vitrectomy (PPV) was performed in one eye. In the 8 eyes of the observation group, VH recurrence occurred in 2 eyes, subsequent PPV in 1 eye. The rate of VH recurrence and PPV was lower in the injection group, however, the difference was not statistically significant( P=0.576, 1.000). In terms of complications, minor subconjunctival hemorrhage occurred in 2 eyes and minor corneal epithelial injury occurred in 1 eye in the injection group, and all recovered spontaneously within a short time. In the injection group, 9 eyes had wide-angle fundus photography before and after IVR treatment. There was no significant change in the range of peripheral retinoschisis after treatment. No obvious proliferative vitreoretinopathy, infectious endophthalmitis, retinal detachment, macular hole, complicated cataract, secondary glaucoma or other serious complications were found in all the treated eyes, and there were no systemic complications. Conclusion:Intravitreous anti-VEGF treatment may accelerate the absorption of vitreous hemorrhage in patients with XLRS. No impact is found regarding to the peripheral retinoschisis.

ABSTRACT

Objective:To explore the association of the impaired cognition and the deposition of β-amyloid (Aβ) in normal cognitive (NC) and mild cognitive impairment (MCI).Methods:From December 2018 to January 2021, 305 subjects (113 males, 192 females; age (64.0±7.7) years) who completed neuropsychological tests and MRI in Shanghai Sixth People′s Hospital, Shanghai Jiao Tong University and 18F-florbetapir (AV45) PET imaging in Huashan Hospital, Fudan University were retrospectively analyzed. The subjects were divided into MCI group and NC group based on neuropsychological tests, and each group was further divided into Aβ-positive and Aβ-negative based on PET imaging results. Independent-sample t test, Mann-Whitney U test and χ2 test were used to analyze the data. Results:There were 118 subjects in MCI group and 187 subjects in NC group. The Aβ-positive rate in MCI group (37.3%, 44/118) was higher than that in NC group (26.2%, 49/187; χ2=4.19, P=0.041). The assessment performances of MCI group in general cognitive function, memory function, language function and executive function were inferior to those of NC group ( t values: from -10.63 to -6.31, z values: from -11.01 to -6.03, all P<0.001). The Auditory Verbal Learning Test-Long Delay Recall (AVLT-LDR) score of Aβ-positive subjects was lower than that of Aβ-negative subjects in MCI group (1.00(0.00, 3.00) and 3.00(1.00, 4.00); z=-2.49, P=0.013). The Montreal Cognitive Assessment Basic (MoCA-B) score of Aβ-positive subjects was lower than that of Aβ-negative subjects in NC group (25.29±2.67 and 26.36±2.42; t=-2.61, P=0.010). Conclusion:Compared to Aβ-negative subjects, MCI patients with Aβ-positive perform worse on memory tests, and NC subjects with Aβ-positive perform worse on general cognitive function.

ABSTRACT

Objective:To investigate the value of three-dimensional (3D) CT in diagnosing cricoarytenoid dislocation.Methods:From January 2021 to December 2021, 31 patients with unilateral cricoarytenoid dislocation who had been treated by reduction forceps at the Affiliated BenQ Hospital of Nanjing Medical University were collected retrospectively, and their voice recovered or improved significantly after therapy. The preoperative CT images were reconstructed by volume rendering (VR). The dislocated side (left and right), type of dislocation (total dislocation and subluxation), and dislocation direction (anterior, posterior, internal and external dislocation) of cricoarytenoid dislocation were observed. According to arytenoid articular surface of cricoid cartilage exposed completely or not (caused by arytenoid displacement), they were divided into complete dislocation and subluxation. According to the direction of arytenoid displacement and the part of arytenoid articular surface of cricoid cartilage exposed, they were divided into anterior, posterior, internal and external dislocation. According to the shape of the vocal cords on laryngoscope, anterior and posterior dislocation of each case was judged, and then compared with that of CT.Results:On VR images, there were 28 cases of cricoarytenoid subluxation (90.3%, 28/31) and 3 cases of complete dislocation (9.7%, 3/31). Left cricoarytenoid dislocation was 26 cases (83.9%, 26/31) and right cricoarytenoid dislocation was 5 cases (16.1%, 5/31). Posterior dislocation was 28 cases (90.3%, 28/31) and anterior dislocation was 3 cases (9.7%, 3/31). There were 23 cases of internal dislocation (74.2%, 23/31), 2 cases of external dislocation (6.4%, 2/31), and 6 cases without obvious internal and external dislocation (19.4%, 6/31). Three cases of complete dislocation were left posterior internal dislocation.There were 24 cases of left posterior dislocation (77.4%, 24/31), 4 cases of right posterior dislocation (12.9%, 4/31), 2 cases of left anterior dislocation (6.4%, 2/31) and 1 case of right anterior dislocation (3.2%, 1/31). On laryngoscope, there were 19 cases of posterior dislocation (61.3%, 19/31), 9 cases of anterior dislocation (29.0%, 9/31), 3 cases were difficult to assess (9.7%, 3/31) because of aryepiglottic fold covering. Sixteen cases (55.2%, 16/28) were consistent with 3D CT, and 12 cases (42.8%, 12/28) were inconsistent.Conclusion:The 3D CT is a reliable method to evaluate cricoarytenoid dislocation, which can show dislocated side, type and direction of cricoarytenoid dislocation clearly.

ABSTRACT

Objective:To investigate the factors affecting the prognosis of stage Ⅰa2-Ⅱa2 cervical cancer after laparoscopic radical hysterectomy (LRH), and to compare the prognosis and recurrence sites of patients with different colpotomy paths.Methods:The clinical data of 965 patients with stage Ⅰa2-Ⅱa2 cervical cancer who underwent LRH in the First Affiliated Hospital of Army Medical University from January 2015 to December 2018 were collected. The median age was 47.0 years of all patients with a median follow-up of 62 months (48-74 months). Cox regression was used to perform the univariate and multivariate analysis of the clinicopathological factors associated with the prognosis that included disease-free survival (DFS) and overall survival (OS). Patients were categorized into LRH through vaginal colpotomy (VC group, n=475) and LRH through intracorporeal colpotomy (IC group, n=490) according to the colpotomic approaches. The prognosis and recurrence sites of patients in each group were compared. Results:(1) During the follow-up period, 137 cases recurred (14.2%, 137/965) and 98 cases died (10.2%, 98/965). The 5-year DFS and OS were 85.8% and 89.9%, respectively. In univariate analysis, positive vaginal margin (PVM) was significantly affected the 5-year OS of patients with cervical cancer ( P=0.023), while clinical stage, maximum diameter of tumor, degree of pathological differentiation, lymph node metastasis (LNM), depth of cervical stromal invasion, parametrium involvement, and uterine corpus invasion (UCI) were significantly associated with 5-year DFS and OS in patients with cervical cancer (all P<0.05). In multivariate analysis, clinical stage ( HR=1.882, 95% CI: 1.305-2.716), LNM ( HR=2.178, 95% CI: 1.483-3.200) and UCI ( HR=3.650, 95% CI: 1.906-6.988) were independent risk factors of 5-year DFS (all P<0.001). Clinical stage ( HR=2.500, 95% CI: 1.580-3.956), LNM ( HR=2.053, 95% CI: 1.309-3.218), UCI ( HR=3.984, 95%C I: 1.917-8.280), PVM ( HR=3.235, 95% CI: 1.021-10.244) were independent risk factors of 5-year OS (all P<0.05). (2) Different colpotomy paths did not significantly affect the 5-year DFS and OS of patients with stage Ⅰa2-Ⅱa2 cervical cancer. The 5-year DFS in VC group and IC group were 85.9% and 85.6% ( P=0.794), and the 5-year OS were 90.8% and 89.3% ( P=0.966), respectively. Recurrence patterns consisted of intraperitoneal recurrence, pelvic recurrence, vaginal stump recurrence, and lymph node and distant metastasis. The intraperitoneal recurrence rate of VC group was significantly lower than that of IC group [0.6%(3/468) vs 2.3% (11/485), P=0.037], while the rates of pelvic recurrence, vaginal stump recurrence, lymph node and distant metastasis and overall recurrence were not significantly different between two groups (all P>0.05). Subgroup analysis of patients with different clinical stages, LNM and UCI showed that statistical differences of the intraperitoneal recurrence rates between two groups were only in patients without LNM (0.5% vs 2.3%, P=0.030) or without UCI (0.7% vs 2.3%, P=0.037). Conclusions:Clinical stage, LNM, PVM and UCI are independent risk factors for the prognosis of patients with stage Ⅰa2-Ⅱa2 cervical cancer. For patients without LNM or UCI, LRH through VC could reduce the intraperitoneal recurrence rate, while it is not enough to improve 5-year DFS and OS of patients. Low proportion of intraperitoneal recurrence, intra-operative tumor cells spillage to vagina stump and pelvic cavity might be the explanation.

ABSTRACT

Objective:To evaluate the fetal adrenal gland volume (AGV) and corrected adrenal gland volume (cAGV) in intrauterine growth restriction (IUGR) fetuses and observe their associations with the adverse perinatal outcomes.Methods:From February 2021 to August 2022, 32 IUGR fetuses who underwent fetal ultrasound examination in the Second Xiangya Hospital of Central South University were prospectively selected as the IUGR group, and 32 normal fetuses matched for gestational age during the same period were selected as the control group. Three-dimensional ultrasound was used to obtain fetal adrenal volume images, and the virtual organ computer-aided analysis (VOCAL) was used to measure AGV, then the cAGV was calculated. The values of AGV and cAGV were appropriately compared between the IUGR and the control groups. The pregnancy outcomes were noted. Multiple logistic regression analysis was employed to evaluate the relationship between the cAGV and adverse perinatal outcomes in IUGR fetus, with maternal age and the CPR included as covariates to control for confounding factors.Results:A total of 32 fetuses with IUGR and 32 controls were involved in this prospective study. There was no significant difference in the AGV between these two groups ( P=0.417). The cAGV of the IUGR fetus was substantially larger than that of the normal fetus ( P=0.034). In the multivariate logistic regression analysis, after adjusting for maternal age and fetal CPR, the fetal cAGV was noticeably associated with the fetal distress (adjusted OR=0.005, 95% CI=0.000-0.587, P=0.029) and the total adverse perinatal outcomes (adjusted OR=0.014, 95% CI=0.000-0.475, P=0.018). Conclusions:The value of cAGV is increased in the IUGR fetuses and associated with adverse perinatal outcomes. The evaluation of fetal AGV could be beneficial to monitoring and managing IUGR fetuses.

ABSTRACT

Objective To investigate the role of angiotensin-converting enzyme (ACE) in the reproduction of Culex pipiens pallens, so as to provide insights into selection of targets for controlling mosquito vector populations. Methods Cx. pipiens pallens was collected from Tangkou County, Shandong Province in 2009. Female and male mosquitoes were selected at 72 hours post-eclosion, and quantitative real-time reverse transcription PCR (qPCR) assay was used to detect the expression of ACE gene in the whole body and reproductive tissues of male mosquitoes and fertilized female mosquitoes before (0 h) and after blood meals (24, 48, 72 h), respectively. Then, 150 female and 150 male mosquitoes at 0 to 4 hours post-eclosion were selected and divided into the wild-type group (WT group), small interfering RNA-negative control group (siNC group) and small interfering RNA-ACE group (siACE group), of 50 mosquitoes in each group. Mosquitoes in the WT group were given no treatment, and mosquitoes in the siNC and siACE groups were given microinjection of siNC and siACE into the hemolymph at a dose of 0.3 μg per mosquito. The knockdown efficiency was checked using qPCR assay, and the reproductive phenotype of mosquitoes was observed. Results The relative ACE gene expression was higher in the whole body of male mosquitoes (5.467 ± 1.006) relative to females (1.199 ± 0.241) (t = 5.835, P = 0.004) at 72 h post-eclosion, and the highest ACE expression was seen in reproductive tissues of male mosquitoes (199.100 ± 24.429), which was 188.3 times higher than in remaining tissues (1.057 ± 0.340) (t = 6.602, P = 0.002). Blood meal induced high ACE expression in all body tissues of fertilized female mosquitoes, with peak expression at 24 h after blood meals (14.957 ± 2.815), which was 14.8 times higher than that before blood meals (1.009 ± 0.139) (P = 0.002). The transcriptional level of ACEs continued to increase in the ovaries of female mosquitoes after blood meals during the vitellogenesis phase, peaking at 48 h after blood meals (5.500 ± 0.734), which was 5.1 times higher than that before blood meals (1.072 ± 0.178) (P = 0.002). Small RNA interference targeting ACE resulted in a 57.2% reduction in ACE expression in female mosquitoes in the siACE group (0.430 ± 0.070) relative to the siNC group (1.002 ± 0.070) (P = 0.001), and a 41.1% reduction in male mosquitoes in the siACE group (0.588 ± 0.067) relative to the siNC group (1.008 ± 0.131) (P = 0.016). Knockdown of ACE expression resulted in a 48.0% decrease in the number of eggs laid by female mosquitoes in the siACE group [(94.000 ± 27.386) eggs] relative to the siNC group [(180.800 ± 27.386)] (P < 0.001), and a 45.0% decrease in the number of eggs laid by wild female mosquitoes mated with males in the siACE group [(104.500 ± 20.965) eggs] relative to the siNC group [(190.050 ± 10.698) eggs] (P < 0.001). Conclusions Reduced ACE expression may inhibit the fecundity of male and female mosquitoes, and ACE may be as a potential target for mosquito vector population suppression.

ABSTRACT

Background@#and Purpose A systematic review and meta-analysis was performed of the outcome of Coronavirus disease 2019 (COVID-19) infection in patients with multiple sclerosis (MS) who received disease-modifying therapies (DMTs). @*Methods@#Relevant studies published before November 2022 in the PubMed, Cochrane Library, Chinese National Knowledge Infrastructure, and Web of Science databases were retrieved using the following search expression: (“multiple sclerosis” OR “MS”) AND (“DMT” OR “disease modifying therapies”) AND (“COVID-19”). Two authors independently screened the articles and extracted the data. Qualitative analyses and a meta-analysis constituted 22 of the 794 retrieved articles. Differences in the hospitalization and mortality rates were used as the main measures of efficacy, and the meta-analysis was performed using RevMan software. @*Results@#22 clinical trials were selected. The hospitalization rate was lower in the 3,216 patients who received DMTs than in the 774 patients who did not receive any treatment, with a moderate effect size of 0.43 (p<0.00001). The mortality rate was also lower among patients with MS treated using DMTs than in controls (odds ratio [OR]=0.19, 95% confidence interval [CI]=0.13–0.27, p<0.00001). The hospitalization rates for COVID-19 infection in patients with MS treated with anti-CD20 therapy also increased markedly (OR=3.32, 95% CI=2.63–4.20, p<0.00001). However, there was no significant difference between patients with MS who did and did not receive DMTs. @*Conclusions@#In summary, the application of DMTs was found to be valuable for patients with MS infected with COVID-19. However, more clinical studies are needed to determine the use of anti-CD20 drugs in patients with MS during the COVID-19 pandemic.

ABSTRACT

Objectives: To examine the impact of probiotics on the lung development of preterm birth of Bama pig. Methods: From April 2020 to October 2021, this animal experimental research was performed by setting up preterm (birth at gestation 104 d), full-term (birth at gestation 113 d), preterm with probiotics (birth at gestation 104 d treated with probiotics given at 3 d after birth), and full-term with probiotics (birth at gestation 113 d treated with probiotics given at 3 d after birth) groups and using the preterm Bama minipig model, the body weights were recorded and lung, ileum, and intestinal content samples were collected at birth, 4 days, 9 days, and 21 days after births of the piglets in preterm and full-term groups, the same samples were collected on 9 days after births of the piglets in preterm with probiotics and full-term with probiotics groups. The body weight and radial alveolar counts (RAC) were compared to evaluate the lung development of the piglets. The lengths of ileal villus were compared to evaluate the development of ileum. The composition structures of bacteria in ileum were analyzed by 16 S rRNA sequencing. The statistical analyses between different groups were performed by t test. Results: There were totally 30 piglets (16 female piglets and 14 male piglets) involving 12 piglets in preterm and full-term groups respectively and 3 piglets in preterm with probiotics and full-term with probiotics groups respectively. The body weights of the piglets in preterm group were lower than those in full-term group at 4, 9 and 21 d after birth ((507±27) vs. (694±56) g, (620±35) vs. (1 092±154) g, (1 660±210) vs. (2 960±418) g,t=2.96, 2.99, 2.78, all P<0.05). The alveolarization of the preterm piglets at 9 days after birth was significantly lower than that of the full-term piglets at the equivalent time point (4.00±0.29 vs. 6.11±0.35, t=4.64, P<0.01). The bacteria genus with the highest abundance in ileum were all different between the preterm and the full-term groups at 4, 9 and 21 d after birth (4 d Escherichia-Shigella (26.63%) and Enterococcus (30.48%) respectively;9 d Turicibacter (35.94%) and Lactobacillus (27.33%) respectively;21 d Escherichia-Shigella (28.02%) and Lactobacillus (46.29%) respectively). The heights of ileal villus of the preterm piglets at 9 d after birth were significantly lower than those of the full-term minipigs at the equivalent time point ((297±21) vs. (411±32) μm, t=3.01, P=0.007).There were both no differences in the body weight and alveolarization ((692±36) vs. (767±67) g, 5.44±0.34 vs. 5.89±0.26, t=0.74, 1.04, both P>0.05) between the piglets in preterm with probiotics group and those in full-term with probiotics group. Turicibacter was the dominant genus in the piglets of both preterm with probiotics and the full-term with probiotics groups. The heights of ileal villus of the piglets in preterm with probiotics group were significantly longer that those of the piglets in preterm group ((371±13) vs. (297±21) μm, t=3.04, P=0.006), and were both not significantly different from those of the piglets in full-term with probiotics group and full-term group ((371±13) vs. (338±12) and (411±32) μm, t=1.90, 1.15, both P>0.05). Conclusions: Premature birth could impact the lung alveolarization of piglets. The probiotics could improve the lung alveolarization of preterm minipigs by promoting the development of ileum.

ABSTRACT

Objective:To explore the prognostic factors of epithelial ovarian carcinoma (EOC), construct a nomogram model, and evaluate the prognosis of EOC patients.Methods:A retrospective analysis was performed on clinicopathological data of 208 cases of EOC patients who received initial treatment in the First Affiliated Hospital of Army Medical University from August 11, 2016 to July 11, 2018, including age, preoperative ascites, preoperative neoadjuvant chemotherapy, surgical method, pathological type, pathological differentiation degree, surgical pathology stage, preoperative and post-chemotherapy serum cancer antigen 125 (CA 125) level, human epididymal protein 4 (HE4) level, platelet count and platelet/lymphocyte number ratio (PLR). The univariate and multivariate Cox risk ratio models were used to analyze the related factors affecting progression free survival (PFS) in EOC patients, and the prediction nomogram of PFS in EOC patients was established to evaluate its efficacy in predicting PFS. Results:Univariate analysis showed that preoperative neoadjuvant chemotherapy, pathological type, pathological differentiation degree, surgical pathology stage, serum CA 125 and HE4 level before operation and after chemotherapy, platelet count and PLR before operation and after chemotherapy were significantly correlated with PFS in EOC patients (all P<0.05). Multivariate analysis showed that surgical pathology stage, preoperative PLR, serum CA 125 and HE4 level after chemotherapy were independent prognostic factors affecting PFS of EOC patients (all P<0.01). The index coefficient of the prediction model for the prognosis of EOC patients established by this method was 0.749 (95% CI: 0.699-0.798), which had good prediction ability, and could help clinicians to more accurately evaluate the prognosis of EOC patients. Conclusion:The nomogram model constructed based on surgical pathology stage, preoperative PLR, serum CA 125 and HE4 level after chemotherapy could effectively predict the PFS of EOC patients after initial treatment, could help clinicians to screen high-risk patients, provide individualized treatment, and improve the prognosis of EOC patients.

ABSTRACT

Obtaining high-quality embryos is one of the key factors to improve the clinical pregnancy rate of assisted reproductive technologies (ART). So far, the clinical evaluation of embryo quality depends on embryo morphology. However, the clinical pregnancy rate is still low. Therefore, new indicators are needed to further improve the evaluation of embryo quality. Several studies have shown that the decrease of sperm-specific protein actin-like 7A (ACTL7A) leaded to low fertilization rate, poor embryo development, and even infertility. The aim of this study was to study whether the different expression levels of ACTL7A on sperm can be used as a biomarker for predicting embryo quality. In this study, excluding the factors of severe female infertility, a total of 281 sperm samples were collected to compare the ACTL7A expression levels of sperms with high and low effective embryo rates and analyze the correlation between protein levels and in-vitro fertilization (IVF) laboratory outcomes. Our results indicated that the ACTL7A levels were significantly reduced in sperm samples presenting poor embryo quality. Furthermore, the protein levels showed a significant correlation with fertilization outcomes of ART. ACTL7A has the potential to be a biomarker for predicting success rate of fertilization and effective embryo and the possibility of embryo arrest. In conclusion, sperm-specific protein ACTL7A has a strong correlation with IVF laboratory outcomes and plays important roles in fertilization and embryo development.

ABSTRACT

Objective:By comparing the clinical effect of minimally invasive hollow screw internal fixation Assisted by orthopedic robot (TiRobot) and O-arm navigation in the treatment of pelvic fractures, and practicability and security of both treatments were evaluated.Methods:Retrospective analysis of data of 42 cases of Tile C type pelvic fractures was employed during June 2017 to June 2020. Among them, 32 cases, twenty-four men, eight women, aged 34±6.2 years (range 24-68 years), were treated with percutaneous screw fixation guided by O-arm X wire instrument. According to Tile classification, there were 3 cases of C1.1 type, 8 cases of C1.2 type and 21case of C1.3 type. According to the Denis classification of sacral fractures, 17 cases were in zone I, and 8 cases in zone II. Ten patients, eight males and two females, aged 36±5.2 years (range 19-62 years) were treated by percutaneous screw fixation assisted by orthopedic robot. According to Tile classification, there were 1 case of C1.1 type, 2 cases of C1.2 type and 7 cases of C1.3 type. According to the Denis classification of sacral fractures, there were 5cases in zone I, 2 cases in zone II. For those who got obviously displaced pelvic fractures, Starr frames were used and then internal fixation was used to fix pelvic anterior ring and posterior ring injury respectively. Based on the times of needle adjustments, intraoperative fluoroscopy time, good screw position and incidence of complications two groups were statistically analysed. Matta score was employed to evaluate the quality of fracture reduction, while the Majeed score was employed to evaluate the clinical efficacy. Through the two groups of cases guide needle adjustment times, intraoperative fluoroscopy time, screw position excellent and good rate and the incidence of complications, which were statistically analyzed.Results:All screw positions were confirmed by CT scan after operation. The average time required for each screw placement of the O-arm group was 7.36±2.63 s, of the robot group was 6.80±3.20 s, so difference was not statistically significant ( P<0.05). An average of screw adjustments per one screw was 1.56±0.02 times by O-arm, and by the robot group was 0.34±0.06 times, so differences between the two groups were statistically significant ( P>0.05). The average operating time of O-arm group was 53.86±15.06 min, while the robot group was 52.52±15.14 min, so differences between the two groups were not statistically significant ( P>0.05). Position distribution of screw placement in two groups, all screws in O-arm group of position evaluations were excellent, excellent rate was 100%, all screw position evaluations by robot were excellent, excellent rate was 100%, so difference in screw distribution between the two groups was not statistically significant ( P>0.05). All cases were followed up for 6-12 months. Fracture healing time: 34.6±8.6 weeks for O-arm group, 33.4±9.4 weeks for robot group. Comparison between the two groups was not statistically significant ( P>0.05). Majeed score of O-arm group was 55-87, including Excellence of 17 cases, goodness of 9, fairness of 6. The rate of excellence and goodness was 81.2%, while robot group was 76-95, and that were excellent 7 cases,1 good, and the excellent and good rate was 80%, there was no significant difference between Matta and Majeed score between the two groups ( P>0.05). The incidence of complications between the two groups were no statistically significant ( P>0.05). Conclusion:Orthopedic robot system and O-arm navigation system assisted by percutaneous hollow screw fixation treatment of pelvic anterior and posterior ring injury, which are accurate, safe, minimally invasive, can reduce radiation damage to patients and surgeons. The efficacy were satisfactory. Both treatments are ideal for minimally invasive treatment of pelvic fractures, and the orthopedic robot have advantages of being programmed, standardized, stable and it’s learning curve is shorter.

ABSTRACT

Objective:To explore the effect of CDIO (conceive, design, implement, operate) model workshop training on the training of new nurses in the operating room.Methods:Forty-two nurses with standardized training were selected as the research objects, and they were randomly divided into two groups: observation group ( n=21) and control group ( n=21). The control group used the traditional training method in the operating room, and the observation group used the workshop training based on the CDIO model. SPSS 17.0 was used to statistically analyze the operation skill scores and case scores after training. The measurement data is expressed by (mean±standard deviation), the independent sample t test is used for comparison between the two groups, and the chi-square test is used for the comparison of counting data. Results:After the training, the scores of operating room knowledge assessment of the two groups were (72.31±2.16) points and (73.61±2.18) points respectively, with statistical significance ( P<0.05); the operation skill scores of observation group were (7.42±0.13) points, which were higher than those of the control group (6.62±0.11) points, and the disposal scores of observation group after operation were (7.12±0.20) points, which were higher than those of the control group (6.27±0.16) points, with statistical significance ( P<0.05); the professional quality scores of observation group were (7.41±0.25) points, which were higher than those of the control group (6.55±0.22) points; the adaptability scores of observation group were (7.06±0.22), which were higher than those of control group (6.35±0.21) points, with statistical significance ( P<0.05). Conclusion:The workshop training based on the CDIO model is effective for the training of nurses in the operating room, and the combined application effect is better than the effect of the traditional teaching model, especially for the improvement of practical skills.

ABSTRACT

OBJECTIVE@#To investigate whether blood-brain barrier (BBB) served a key role in the edema-relief effect of bloodletting puncture at hand twelve Jing-well points (HTWP) in traumatic brain injury (TBI) and the potential molecular signaling pathways.@*METHODS@#Adult male Sprague-Dawley rats were assigned to the sham-operated (sham), TBI, and bloodletting puncture (bloodletting) groups (n=24 per group) using a randomized number table. The TBI model rats were induced by cortical contusion and then bloodletting puncture were performed at HTWP twice a day for 2 days. The neurological function and cerebral edema were evaluated by modified neurological severity score (mNSS), cerebral water content, magnetic resonance imaging and hematoxylin and eosin staining. Cerebral blood flow was measured by laser speckles. The protein levels of aquaporin 4 (AQP4), matrix metalloproteinases 9 (MMP9) and mitogen-activated protein kinase pathway (MAPK) signaling were detected by immunofluorescence staining and Western blot.@*RESULTS@#Compared with TBI group, bloodletting puncture improved neurological function at 24 and 48 h, alleviated cerebral edema at 48 h, and reduced the permeability of BBB induced by TBI (all P<0.05). The AQP4 and MMP9 which would disrupt the integrity of BBB were downregulated by bloodletting puncture (P<0.05 or P<0.01). In addition, the extracellular signal-regulated kinase (ERK) and p38 signaling pathways were inhibited by bloodletting puncture (P<0.05).@*CONCLUSIONS@#Bloodletting puncture at HTWP might play a significant role in protecting BBB through regulating the expressions of MMP9 and AQP4 as well as corresponding regulatory upstream ERK and p38 signaling pathways. Therefore, bloodletting puncture at HTWP may be a promising therapeutic strategy for TBI-induced cerebral edema.
