In this article 95 patients were chcked by air-CT cisternography and 43 cases with neurovascular contact were diagnosed. The results showed that NVC was the most common to be affected in CPA diseases. NVC was the cause of the symptoms. Using air-CT could diag- nose NVC, locatethe position, extend and complication as well as supply the accordance for surgury. We also discussed the mechanism of causing symptoms when NVC was normal of patholoic.

At present, the artificial materials for cranial repair include methylsilicone rubber, titanium net, bonwe cement and stainless steel sil net, etc. Titanium net, organic glass, methylsilicone rubber and bone cement are easy to operate, but they are not satisfactory as an ideal material of repairing cranial defects because they only contributes to partial functional alternation as a foreign implant. High cost and long periodicity of tissue engineered bone lead to limit its application in clinics as an ideal repair material of bone defects. With the advanced development of biomaterials study and the deeper manufacture of industrialized tissue engineered products, this technology will achieve a large-scale application of clinical practice.

Objective To analyze the effect of nimodipine on prevention and treatment of patients with severe burn sepsis. MethodsTwenty-eight cases were randomized into nimodipine treatment group (n = 14) and routine group (n = 14). Besides general chnical therapy scheme treatment,the treatment group was administrated with saline plus nimodipine (15 μg/(kg · h)), while the routine group was given saline only. The Plasma concentration levels of total calcium (Ca2 +), free calcium (iCa2 +), C-reactive protein (CRP), procalcitonin (PCT), tunmor necrosis factor α (TNF-α), brain natriuretic petide (BNP) and interleukin-6 (IL-6) were measured. The hemodynamic indices of patients with severely burn sepsis were determined by transesophageal echo-Doppler device,hemodynamic indices including aortic blood flow (ABF), left ventricle ejection time (LVET), max acceleration (ACC), total systemic vascular resistance (TSVR). Mean artery pressure (MAP) and heart rate (HR) were measured. ResultsABF, ACC, LVET and TSVR were improved after therapy in the routine group(t = 3.93,3. 37,3.75,7.02) (P ＜ 0.01 or 0.05). ABF, ACC, LVET and TSVR were mproved after therapy in the treatment group (t =6.46,4.98,6.29,4.60) (P ＜0.01 or 0.05). ABF, ACC and LVET were increased after general clinical therapy scheme and was markedly increased in the treatment group (t = 2.29,2.07,2.23)(P＜0.01～0.05).TSVR was decreased after general clinical therapy scheme and was markedly decreased in the treatment group (t =2.14) (P＜0.05). Plasma TNF-α, IL-6 and CRP levels were decreased after therapy in the routine group (t =2.38,2.29,2.45)(P＜0.01 or 0.05). Plasma TNF-α, IL-6 and CRP levels were decreased after therapy in the treatment group (t =4.04,4.04,2.56)(P ＜0.01or 0.05). Plasma PCT and BNP levels were decreased in the treatment group (t =5.45,2. 44) (P ＜ 0.01 or 0.05). TNF-α, IL-6, CRP, PCT and BNP were decreased after generalclinical therapy scheme and was markedly decreased in the treatment group (t = 2.20,2.17,2.19,2.17,2.61) (P ＜0.01 or 0.05). Plasma Ca2+ and iCa2+ levels were decreased. However,MAP were increased in the two groups, although no difference was found between the two group(P ＞0.05). ConclusionsEarly applying of calcium channel blockers (CCB) can markedly inhibit the degree of inflammatory medium in serum, thereby preventing the development of excessive inflammation response and subsequent multiple organ dysfunction syndrome associated with severely burned sepsis. It can effectively inhibit intracellular Ca2+ overload caused by myocadial infection injury,which may contribute to the effect of acupuncture in reducing myocardial injury and protecting myocardial performance and improving prognosis.

Objective:To evaluate serum complement C1q tumor necrosis factor related proteins-3 (CTRP-3) and D-dimer (D-D) in predicting hyperacute transformation after thrombolysis in patients with cerebral infarction, and their correlation with brain injury.Methods:One hundred and sixty patients with cerebral infarction admitted in our hospital from August 2016 to August 2019 were enrolled in the study. The hyperacute transformation occurred in 29 cases after intravenous thrombolysis (occurrence group) and did not occur in 131 cases (non-occurrence group). The serum CTRP-3, D-D levels and other factors that may cause hyperacute transformation were compared between the occurrence group and the non-occurrence group. Logistic regression analysis was used to analyze the risk factors of cerebral hemorrhage. The predictive values of serum CTRP-3 and D-D for hyperacute transformation in patients with cerebral infarction were analyzed with receiver operating characteristic (ROC)curve. The correlation between serum CTRP-3, D-D and brain injury was analyzed by Pearson correlation coefficient method.Results:The National Institute of Health stroke scale (NIHSS) score [(18.6±2.2) points vs. (14.0±2.1) points, t=10.62, P<0.01], proportion of infarct diameter >5 cm [69.0%(20/29) vs. 39.7%(52/131), χ 2=8.22, P<0.01], trial fibrillation rate[72.4%(21/29) vs. 44.3%(59/131), χ 2=7.52, P<0.01], and serum D-D levels [(3.02±0.31) mg/L vs. (2.24±0.23) mg/L, t=15.44, P<0.01] of the occurrence group were significantly higher than those of the non-occurrence group; while the serum CTRP-3 levels were lower than those of the non-occurrence group [(251.3±26.9) μg/L vs. (285.7±29.2) μg/L, t=5.82, P<0.01], the onset-to-needle time (OTN) was longer than that of the non-onset group [(4.61±0.43) h vs. (2.96±0.52) h, t=15.91, P<0.01]. Logistic regression analysis showed that pre-thrombosis NIHSS ( OR=1.69, 95 %CI: 1.02-2.15, P<0.01), proportion of infarct diamete r>5 cm ( OR=3.73, 95 %CI: 1.96-5.10, P=0.001), atrial fibrillation ( OR=2.14, 95 %CI: 1.25-2.96, P<0.01), OTN ( OR=3.44, 95 %CI: 1.85-5.02, P<0.01), serum DD ( OR=2.37, 95 %CI: 1.56-3.30, P<0.01) and serum CTRP-3 ( OR=2.9 d, 95 %CI: 1.91-4.25, P<0.01) were risk factors for hyperacute transformation in patients with cerebral infarction. ROC results showed that the area under the curve (AUC) of CTRP-3 and D-D for predicting hyperacute transformation in patients with cerebral infarction were 0.723 and 0.796, respectively; and the AUC of the combination of two indicators was 0.823. The anterior cerebral infarction occurred in 28 cases, the posterior cerebral infarction occured in 132 cases. The NIHSS score were(18.7±2.1)points and (14.0±1.9)points,respectively,and the modified Rankin Scale(mRS) score were(3.8±0.5)points and(3.2±0.6) points. Pearson correlation analysis showed that the serum CTRP-3 was negatively correlated with the NIHSS score of brain damage in patients with anterior circulation cerebral infarction ( r=-0.72, P<0.01), and the correlation was less strong with the NIHSS score in patients with posterior circulation cerebral infarction ( r=-0.35, P<0.01). The serum D-D was strongly positively correlated with NIHSS score of brain damage in patients with anterior circulation cerebral infarction ( r=0.88, P<0.01), and it was less strong with NIHSS score in patients with posterior circulation cerebral infarction ( r=0.24, P<0.01). The serum CTRP-3 was strongly positively correlated with brain injury mRS score ( r=0.80, P<0.01), and serum D-D was strongly negatively correlated with brain injury mRS score ( r=-0.76, P<0.01). Conclusion:The combined detection of serum CTRP-3 and D-D has a high predictive value for the occurrence of cerebral hemorrhage in hyperacute transformation after thrombolysis in patients with cerebral infarction, and two indicators have a certain correlation with brain injury of patients.

Objective:To compare magnetic resonance imaging (MRI)-based and computed tomography (CT)-based target volume delineation and dose coverage in partial breast irradiation (PBI) for patients with breast cancer, aiming to explore the application value of MRI localization in PBI after breast-conserving surgery.Methods:Twenty-nine patients with early breast cancer underwent simulating CT and MRI scans in a supine position. The cavity visualization score (CVS) of tumor bed (TB) was evaluated. The TB, clinical target volume (CTV), planning target volume (PTV) were delineated on CT and MRI images, and then statistically compared. Conformity indices (CI) between CT- and MRI-defined target volumes were calculated. PBI treatment plan of 40 Gy in 10 fractions was designed based on PTV-CT, and the dose coverage for PTV-MRI was evaluated.Results:The CVS on CT and MRI images was 2.97±1.40 vs. 3.10±1.40( P=0.408). The volumes of TB, CTV, PTV on MRI were significantly larger than those on CT, (24.48±16.60) cm 3vs. (38.00±19.77) cm 3, (126.76±56.81) cm 3vs. (168.42±70.54) cm 3, (216.63±81.99) cm 3vs. (279.24±101.55) cm 3, respectively, whereas the increasing percentage of CTV and PTV were significantly smaller than those of TB. The CI between CT-based and MRI-based TB, CTV, PTV were 0.43±0.13, 0.66±0.11, 0.70±0.09( P<0.001), respectively. The median percentage of PTV-MRI receiving 40 Gy dose was 81.9%(62.3% to 92.4%), significantly lower than 95.6%(95.0%~97.5%) of PTV-CT. Conclusions:The CVS between CT and MRI is not significantly different, but the MRI-based TB, CTV, PTV are significantly larger than CT-based values. The PTV-MRI is of underdose if PBI treatment plan is designed for PTV-CT. As a supplement of CT scan, MRI can enhance the accuracy of TB delineation after breast-onserving surgery.

Objective: To analyze the failure patterns of locoregional recurrence (LRR) and investigate the range of radiotherapy in T_1-2N₁ breast cancer patients undergoing modified radical mastectomy. Methods: From September 1997 to April 2015, 2472 women with T_1-2N₁ breast cancer after modified radical mastectomy without neoadjuvant systemic therapy were treated in our hospital. 1898 patients who did not undergo adjuvant radiotherapy were included in this study. The distribution of accumulated LRR was analyzed. The LR and RR rates were estimated by the Kaplan-Meier method, and the prognostic factors were identified in univariate analyses with Log-rank test. Multivariate analysis was performed using Cox logistic regression analysis. Results: With a median follow-up of 71.3 months (range 1.1-194.6), 164 patients had LRR, including supraclavicular/infraclavicular lymph nodes in 106(65%), chest wall in 69(42%), axilla in 39(24%) and internal mammary lymph nodes (IMNs) in 19 patients (12%). In multivariate analysis, age (>45 years vs.≤45 years), tumor location (other quadrants vs. inner quadrant), T stage (T₁ vs. T₂), the number of positive axillary lymph nodes (1 vs. 2-3), hormone receptor status (positive vs. negative) were significant prognostic factors for both LR and RR. Conclusions In patients with T_1-2N₁ breast cancer after modified radical mastectomy, the most common LRR site is supraclavicular/infraclavicular nodal region, followed by chest wall. The axillary or IMN recurrence is rare. The prognostic factors for LR and RR are similar, which indicates that supraclavicular/infraclavicular and chest wall irradiation should be considered for postmastectomy radiotherapy.

Objective:To investigate the efficacy of osteochondral fragment fixation using bioabsorbable pins for Hepple Ⅱ osteochondral lesions of the talus (OLT) in adolescents.Methods:Retrospective case analysis was used. The clinical data and follow-up results of 13 adolescent patients (13 feet) with Hepple Ⅱ OLT were all treated with osteochondral fragment fixation using bioabsorbable pins admitted to Shanghai Sixth People′s Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from January 2017 to December 2021 were retrospectively analyzed. There were 7 males and 6 females, with 13 right feet. The age was (14.85±2.23) years old, ranged from 12 to 18 years old. According to the American orthopedic foot and ankle society (AOFAS) ankle-hindfoot score, visual analogue scale (VAS) and SF-36 score before operation and at the last follow-up were used to evaluate the efficacy and function of the patients. Measurement data with normal distribution were represented as mean ± standard deviation( ± s), and the comparison between groups was conducted using the t-test; The mearsurement data with skewness distribution were expressed by M( Q1, Q3), and rank-sum test was used for inter-group comparison. Results:Thirteen adolescent patients (13 feet) with Hepple Ⅱ OLT underwent surgery successfully and were followed up for (25.54±9.95) months. All wounds healed by first intention, and no complications such as wound infection and delayed healing occurred. Preoperative AOFAS ankle-posterior foot score, VAS and SF-36 score were 58.62±3.55, 7.00 (6.50, 8.00) and 68.38±4.81, respectively. At the last follow-up, the scores were 97.38±2.73, 1.00 (0.00, 1.00), 91.15±4.28, respectively, and the results were significantly improved at the last follow-up, with the difference between the two groups statistically significant( P<0.05). Conclusion:Osteochondral fragment fixation using bioabsorbable pins which can promote cartilage repair, significantly improve symptoms, and achieve better clinical satisfaction with fewer complications, is a safe and effective surgical treatment option for Hepple Ⅱ OLT in adolescents with satisfactory short-term clinical outcomes.

Objective To study the effect of deep inspiration breath-hold(DIBH)technique on the heart dose in whole breast irradiation(WBI)for left breast cancer after breast-conserving surgery, and to investigate the anatomical factors for heart dose. Methods Fifteen patients with left breast cancer who received WBI after breast-conserving surgery and met breathing control requirements were prospectively enrolled as subjects. Simulated CT scans were performed during free breathing(FB)and DIBH. The WBI plans were optimized based on DIBH images.The position,volume,and radiation doses to the heart and lung were compared between the status of FB and DIBH. Correlation of heart dose with various anatomical factors was analyzed in FB status. Between-group comparison of categorical data was made by nonparametric Wilcoxon rank test.A two-variable correlation analysis was made by the Pearson method.Results There was no significant difference in heart volume between the status of FB and DIBH(P=0.773).The volume of both lungs was significantly larger in DIBH status than in FB status(P=0.001). The mean and maximum doses and V5-V40for the heart,left anterior descending coronary artery,left ventricle,right ventricle,and left lung were significantly lower in DIBH status than in FB status(all P<0.05). The greater DIBH increased the lung volume,the greater the mean heart dose decreased. In FB status,the left breast volume,heart-to-lung volume ratio,distance between the inferior margins of breast and heart,and maximum heart margin distance showed a linear correlation with heart dose. Particularly, the heart-to-lung volume ratio and maximum heart margin distance were independently correlated with heart dose. Conclusions DIBH technique in WBI for left breast cancer after breast-conserving surgery significantly reduces heart and lung doses compared with FB. Changes in lung volume are the basis for improving the relative anatomical location of the heart. The heart-to-lung volume ratio and maximum heart margin distance may provide a reference for DIBH technique.
