ABSTRACT

As a part of the multidisciplinary diagnosis and treatment model of malignant tumors, traditional Chinese medicine (TCM) plays a unique role in increasing efficiency, reducing toxicity, and preventing recurrence and metastasis. It has been gradually recognized that integrated TCM and western medicine should be used in diagnosis and treatment of tumors. Western medicine such as surgery, radiotherapy, chemotherapy, endocrine therapy, targeted therapy, and immunotherapy may act as the main factors that change the syndromes, as they can induce the changes of the tongue and pulse manifestations and symptoms after acting on the body. It is therefore advised to differentiate and analyze the attributes of yin-yang and cold-heat of western medicine as well as its impact on TCM syndromes, and use Chinese herbal medicinals precisely so as to increase efficiency and reduce toxicity. Moreover, it is better to grasp the syndrome evolution trend of modern medicine and predict the disease tendency, so as to improve the accuracy of syndrome differentiation and treatment in TCM under multi-disciplinary diagnosis and treatment model, and promote the maximization of the benefits of integrated TCM and western medicine in treating tumors.

ABSTRACT

Objective To explore the standardized management mode of the Ethics Committee for organ donation after citizen’s death in hospitals. Methods The situations of ethical review before and after the standardized adjustment of the Ethics Committee of human organ donation in the First Affiliated Hospital of Chongqing Medical University were retrospectively analyzed. Baseline data of donors before and after standardized adjustment of the Ethics Committee of human organ donation were compared. The influence of standardized adjustment of the Ethics Committee on the attendance rate of committee members and duration of ethical review were analyzed. Results No significant differences were observed in donors' ethical review data, such as gender, age and death determination, before and after standardized adjustment of Ethics Committee structure (all P>0.05). Significant difference was noted regarding the cause of death in ethical review (P<0.05). Univariate analysis showed that there were significant differences in the impact of Ethics Committee standardization adjustment and cause of death on the attendance rate of committee members (both P<0.05). Multivariate analysis revealed that gender, cause of death and standardized adjustment of the Ethics Committee were the influencing factors of the attendance rate of committee members, and the attendance rate of committee members after standardized adjustment was higher than that before adjustment (P<0.05). Univariate analysis showed that there were statistically significant differences in the effects of Ethics Committee standardized adjustment, attendance rate of committee members and cause of death on the duration of ethical review (all P<0.05). Multivariate analysis indicated that standardized adjustment of the ethics committee was the influencing factor of the duration of ethical review, and the duration of ethics review after standardized adjustment was shorter than that before adjustment (P<0.05). Conclusions Appropriate arrangement of the total number of ethics committee members and standardizing the review process may improve the efficiency of ethical review. Scientific evaluation mechanism for ethical committee members should be established by dynamically adjusting the ethical committee members, clarifying the responsibilities and tasks of members and secretaries, aiming to further improve standardized management level of ethical review for organ donation after citizen’s death.

ABSTRACT

Objective:To investigate the clinical effect of remote injection device assisted percutaneous vertebroplasty in the treatment of osteoporotic vertebral compression fractures.Methods:Using retrospective research and analysis methods, 168 patients with osteoporotic vertebral compression fractures admitted to Heze Municipal Hospital from September 2019 to August 2020 were selected. A total of 139 cases were followed up, with a follow-up rate of 82.7%, including 22 males and 117 females, with an average age of 74.17 years. According to the different equipment used, they were divided into two groups. Seventy-two cases used remote injection device to assist percutaneous vertebroplasty (observation group), 67 cases used traditional puncture needle puncture percutaneous vertebroplasty (control group). All patients were completed follow-up at 3 months after surgery. The operation time, intraoperative blood loss, bone cement injection volume, bone cement leakage rate, VAS score and ODI score of 1 day, 1 month and 3 months after operation were observed. Measurement data were expressed as ( Mean± SD), using t test, counting data were expressed as percentage [ n(%)], using χ2 test. Results:Both groups of patients successfully completed the operation without complications such as paraplegia, pulmonary embolism, or infection. There was no statistically significant difference between the two groups in operation time of two groups[(47.71±6.05) min vs (47.61±5.66) min, t=0.100, P=0.920]. The intraoperative blood loss of the two groups was no statistically significant difference [(7.08±3.00) mL vs (8.06±3.48) mL, t=1.782, P=0.079]. The difference between two groups of the amount of bone cement injected was statistically significant, [(6.44±1.03) mL vs (5.73±1.41) mL, t=3.369, P=0.001]. The bone cement leakage rate of the observation group was 27.78% (19/72), and the control group was 43.28% (29/67), and there was statistically significant( χ2=4.382, P=0.036). The preoperative VAS score of the observation group was (6.75±1.14) , and the control group was (6.64±1.08), and there was no significant difference between two groups( t=0.583, P=0.561) The VAS scores of the observation group and the control group were (1.28±0.75) and (1.21±0.77) respectively at 1 day after surgery. There was no statistically significant difference between two groups( t=0.583, P=0.588). The VAS scores of the observation group and the control group were (0.89±0.76) and (1.09±0.67) respectively at 1 month after operation. There was no statistically significant difference between two groups( t=1.641, P=0.103). The VAS scores of the observation group and the control group were (0.74±0.63) and (0.87±0.74) respectively at 3 months after operation. There was no statistically significant difference between two groups( t=1.118, P=0.266). The preoperative ODI scores of the observation group and the control group were (60.32±7.46) and (61.96±9.76) respectively, and there was no statistically significant difference between two groups( t=1.121, P=0.264). The ODI scores of the observation group and the control group were (14.93±6.01) and (15.10±6.43) respectively at 1 day after operation, there was no statistically significant difference between two groups( t=0.161, P=0.872). The ODI scores of the observation group and the control group were (10.54±4.24) and (11.31±3.71) respectively at 1 month after operation, and there was no statistically significant difference between two groups( t=1.136, P=0.258). The ODI scores of the observation group and the control group were (10.64±3.70) and (10.39±3.74) respectively at 3 months after operation, and there was no statistically significant difference between two groups( t=0.396, P=0.693). Conclusion:Compared with traditional puncture needle puncture percutaneous vertebroplasty, the remote injection device assisted percutaneous vertebroplasty has a definite clinical effect in the treatment of osteoporotic vertebral compression fractures, and the bone cement leakage rate is low.

ABSTRACT

Objective:To establish an automatic segmentation network based on different receptive fields for gross target volume (GTV) and organs at risk in patients with nasopharyngeal carcinoma.Methods:Radiotherapy data of 100 cases of nasopharyngeal carcinoma including CT images and GTV and organs at risk delineated by the physicians were collected. Ninety plans were randomly selected as the training dataset, and the other 10 plans as the validation dataset. Firstly, the images were subject to three data augmentation methods including center cropping, vertical flipping and rotation (-30°to 30°), and then input into MA_net networks proposed in this study for training. The model performance of networks was assessed by the number of network parameters (NP), floating-point number (FPN), the running memory (RM) and Dice index (DI), and eventually compared with DeeplabV3+ , PSP_net, UNet+ + and U_Net networks.Results:When the input image was in the size of 240×240, MA_net had a NP of 23.20%, 20.10%, 25.55% and 27.11% of these 4 networks, 50.02%, 19.86%, 6.37% and 13.44% for the FPN, 40.63%, 23.60%, 11.58% and 14.99% for the RM, respectively. For the DI of GTV, MA_net was 1.16%, 2.28%, 1.27% and 3.59% higher than these 4 networks. For the average DI of GTV and OAR, MA_net was 0.16%, 1.37%, 0.30% and 0.97% higher than these 4 networks.Conclusion:Compared with those four networks, the proposed MA_net network has slightly higher Dice index with fewer parameters, lower FPN and smaller RM.

ABSTRACT

Objective:To compare the accuracy and generalized robustness of three predictive models of knowledge-based treatment strategies for radiotherapy for optimized model selection.Methods:The clinical radiotherapy plans of 45 prostate cancer (PC) cases and 25 nasopharyngeal cancer (NPC) cases were collected, and analyzed using three models (Z, L and S model), proposed by Zhu et al, Appenzoller et al and Shiraishi et al, respectively, to predict the dose-volume histogram (DVH) of bladder and rectum on PC cases and that of left and right parotid on NPC cases. The prediction error was measured by the difference of area under the predicted DVH and the clinical DVH curves (|V (pre_DVH)-V (clin_DVH)|), where a smaller prediction error implies a greater prediction accuracy. The accuracies of these three models were compared on the single organ at risk (OAR), and the generalized robustness of models was evaluated and compared by calculating the standard deviation of the prediction accuracy on different OAR. Results:For bladder and rectum, the prediction error of L model (0.114 and 0.163, respectively) was significantly higher than those values of Z and S models (≤0.071, P<0.05); for left parotid gland, the predicted error of S model (0.033) did not present significant difference from those values of Z and L models (≤0.025, P>0.05); for right parotid gland, S model (0.033) demonstrated significantly higher prediction error than those of Z and L models (≤0.028, P<0.05). Regarding different OAR, S model showed a lower standard deviation of prediction accuracy when comparing to Z and L models (0.016, 0.018 and 0.060, respectively). Conclusions:In the prediction of DVH in bladder and rectum of PC, Z and S models were more accurate than L model. In contrast, Z and L models demonstrated higher accuracy than S model in the prediction of left and right parotid glands of NPC. In respect to different OAR, the generalized robustness of S model was superior than the other two models.

ABSTRACT

Objective: To explore the value of small FOV scanning in CT-guided of transthoracic needle lung biopsy (TTLB) for small pulmonary nodule (≤20 mm). Methods: CT-guided TTLB was performed in 104 small pulmonary nodules under CT guidance using small FOV (n=38, group A) or common FOV (n=66, group B) scan mode, respectively. The technique and lesion-related variables, including distance to pleura, times of puncture, operating time and pleura-needle angle, etc. were recorded. The incidence of pulmonary hemorrhage and pneumothorax were compared between 2 groups. Results: The total incidence rate of pulmonary hemorrhage in group A was 31.58% (12/38), of ≥grade 2 pulmonary hemorrhage was 2.63% (1/38), while in group B was 66.67% (44/66) and 22.73% (15/66), respectively. The incidence rate of pulmonary hemorrhage in group A was significantly lower than that in group B (χ2=14.172, P=0.001). There was no significant difference of incidence rate of pneumothorax, distance to pleura, times of puncture nor operating time (all P>0.05). Conclusion: The incidence rate of pulmonary hemorrhage after CT-guided TTLB for small pulmonary nodule (≤20 mm), especially higher-grade (≥grade 2) pulmonary hemorrhage might be significantly reduced by using small FOV scanning mode.

ABSTRACT

BACKGROUND:Currently, human umbilical cord derived-mesenchymal stem cel s are mainly for local transplantation, which has some shortcomings, such as large trauma, bleeding, complications, that limit its widespread application in clinical practice. OBJECTIVE:To investigate the feasibility of intravenous transplantation of human umbilical cord derived-mesenchymal stem cel s for repair of spinal cord injury. METHODS:Eighty Wistar rats with spinal cord hitting were divided into five groups:blank control group with no transplantation (n=10), DMEM local transplantation group (n=15), DMEM intravenous transplantation group (n=15), cel local transplantation group (n=20), cel intravenous transplantation group (n=20). The functional recovery of spinal cord injury was observed with Basso, Beattie and Bresnahan scores at regular time as wel as hematoxylin-eosin staining and immunohistochemistry staining. RESULTS AND CONCLUSION:During 1 day to 2 weeks after transplantation, there was no significant difference in the Basso, Beattie and Bresnahan scores between the five groups;within 4-12 weeks after transplantation, the Basso, Beattie and Bresnahan scores were significantly higher in the two cel transplantation groups than the other three groups, but there was no difference between these two cel transplantation groups (P>0.05). Histological observation showed that the number of voids and glial scars was less in the cel local transplantation group and cel intravenous transplantation group compared with the other three groups, and there was also no difference between the two cel transplantation groups. These results indicate that the intravenous transplantation of human umbilical cord derived-mesenchymal stem cel s is similar to the local transplantation in the repair of acute spinal cord injury, which is simple and avoids secondary injuries and various complications. It is recommended that this method provide a new approach for cel transplantation.

ABSTRACT

BACKGROUND: Olfactory ensheathing cell transplantation is a better theray for spinal cord injury, and it becomes one of the most promising treatment methods. Local transplantation is applied currently, with the disadvantages of complex operation, large trauma, repeated transplantation. Looking for a simple and effective way for cell transplantation becomes a hotspot for scholars from various countries.OBJECTIVE: To investigate the effect and possibility of transplantation of olfactory ensheathing cells for treatment of spinal cord injury.METHODS: Wistar rats with T 10 spinal cord hemisecti on were divided into 4 groups: intramedullary local transplantation group (A),vein transplantation group (B), D/F12 transplantation group (C) and control group (D). The functional recovery of rats with spinal cord injury was observed with combined behavioral score at different phases. The tissue sections of each group were made at 5 and 10 weeks postoperatively to observe the axon regeneration and the survival of olfactory ensheathing cells.RESULTS AND CONCLUSION: The experiment showed that the rats transplanted with OECs at injured site and through the vein had more improvement in functional recovery and histological changes than the other two groups. The effect between A group and B group had not significant difference. The method of treating spinal cord injury by transplanting OECs via the vein not only simplifies the operation and avoids many complications but also has good curative effect similar to local transplantation.

ABSTRACT

Objective To evaluate and compare the curative effect between the microinvasive craniopuncture therapy and the clearance of hematoma by craniotomy with small bone flap in treating patients with moderate cerebral hemorrhage (30-60 ml)in the basal ganglion part of the brain. Methods Ninety-five patients with intracerebral hemorrhage were randomly divided into treatment group (microinvasive craniopuncture therapy) and control group (the clearance of hematoma by craniotomy with small bone flap). The main indexes of evaluation were the neurological impairment degree (NID) on the 14th day after treatment, activities of daily living (ADL) by the end of the third month, the incidence rate of complications, and the case fatality during 3 months. Results On the 14th day after treatment, there was no significant difference between the two groups in the NID and the ADL of patients. The incidence rate of respiratory tract infection, gastrointestinal hemorrhage, electrolyte disorder in treatment group [16.33% (8/49), 6.12% (3/49), 6.12% (3/49), respectively] was significantly reduced than those of control group [56.52% (26/46), 21.74%(10/46), 21.74% (10/46),respectively] during hospitalization (P < 0.05). By the end of the third month, there was significant difference in favorable outcomes (Barthel index 95-100) (χ~2 = 18.7524,P =0.0009) and in improving the ADL (MRS)(t =5.2723,P =0.0001) between the two groups [39.13% (18/46), 4.65% (2/43),respectively]. In ease fatality, there was no significant difference between the two groups [6.12% (3/49),6.52% (3/46),respectively]. Conclusion As compared with the clearance of hematoma by craniotomy with small bone flap, the microinvasive craniopuncture therapy can remarkably reduce the incidence of complications, and improve the ADL of patients with moderate cerebral hemorrhage (30-60 ml) in the basal ganglion, and decrease disability without increasing fatality.
