ABSTRACT
Objective To explore the effect of transcutaneous electrical acupoint stimulation bracelet at Neiguan acupoint on the postoperative nausea and vomiting after thyroidectomy under general an-esthesia.Methods Seventy-two female patients underwent thyroidectomy,aged 18-50 years,ASA physical status Ⅰ or Ⅱ,were enrolled.The patients were assigned 1 ∶ 1 to two groups by permuted block randomization:the electrical stimulation group and the control group,36 patients in each group.Before an-esthesia induction,patients in both groups wore domestic transcutaneous electrical acupoint stimulation bracelets,and the electrodes were aimed at Neiguan acupoint.The electrical stimulation group started to stimulate Neiguan acupoint,and adjusted the proper intensity to make the patient feel tingling in the related area of the hand.When the bracelet was fixed firmly,turned it off.At the end of the operation,the bracelet was turned on with the stimulation intensity set before induction for 24 hours.Patients in the control group also wore the bracelet for 24 hours,but it was never turned on.The number of cases of postoperative nausea and vomiting(PONV)and the number of remedial cases of antiemetic drugs were recorded.Results Compared with the control group,the incidence of PONV and postoperative vomiting in the electrical stimula-tion group were significantly reduced within 24 hours after surgery(P<0.05),and the differences were mainly in 1-6 hours after surgery(P<0.05).There was no significant difference in the rate of remedial ca-ses of antiemetic drugs between the two groups at different time periods.Conclusion Transcutaneous electri-cal stimulation bracelet at Neiguan acupoint can effectively reduce the incidence of PONV within 24 hours after thyroidectomy.
ABSTRACT
This article reviews relevant literature on the prevention and treatment of cancer with hesperidin published in the past 10 years by searching electronic databases such as China National Knowledge Infrastructure(CNKI), Wanfang, and PubMed, and summarizes the research progress on the anticancer mechanism of hesperidin. Hesperidin has a wide range of pharmacological effects, including anti-inflammatory, antioxidant, antibacterial, antiviral, anticancer, immune-regulatory, anti-radiation, neuroprotective and cardiovascular protective properties and so on. Its anticancer mechanisms mainly include inhibiting cancer cell proliferation, promoting apoptosis, reducing angiogenesis, inhibiting invasion and migration of cancer cells, regulating immunity and autophagy, and exerting antioxidant and anti-inflammatory effects. As a broad-spectrum anticancer drug, hesperidin manifests chemo-preventive and therapeutic effects across various cancers, contingent upon its multifaceted anticancer mechanisms. Furthermore, this article summarizes the synergistic effects of hesperidin in combination with cisplatin, doxorubicin, cyclophosphamide and paclitaxel. It elucidates that hesperidin can enhance the cytotoxicity of these anticancer drugs against cancer cells while mitigating drug resistance and adverse side effects. Nonetheless, the clinical use is somewhat constrained due to its poor water solubility and limited bioavailability. Therefore, this article also outlines the current strategies for enhancing hesperidin's bioavailability, including structural modification, combination with other chemical substances, and utilization of nano drug carriers.The discovery of derivatives of hesperidin not only preserves the anticancer efficacy of hesperidin, but also effectively overcomes the shortcomings of poor water solubility and low bioavailability of hesperidin, effectively predicting the good application prospects of hesperidin and its derivatives.

ABSTRACT
Objective:By analyzing the clinical phenotypic characteristics and gene sequences of two patients with Treacher Collins syndrome(TCS), the biological causes of the disease were determined. Then discuss the therapeutic effect of hearing intervention after bone bridge implantation. Methods:All clinical data of the two family members were collected, and the patients signed the informed consent. The peripheral blood of the proband and family members was extracted, DNA was extracted for whole exome sequencing, and Sanger sequencing was performed on the family members for the mutation site.TCOF1genetic mutations analysis was performed on the paitents. Then, the hearing threshold and speech recognition rate of family 2 proband were evaluated and compared under the sound field between bare ear and wearing bone bridge. Results:In the two pedigrees, the probands of both families presented with auricle deformity, zygomatic and mandibular hypoplasia, micrognathia, hypotropia of the eye fissure, and hypoplasia of the medial eyelashes. The proband of Family 1 also presents with specific features including right-sided narrow anterior nasal aperture and dental hypoplasia, which were consistent with the clinical diagnosis of Treacher Collins syndrome. Genetic testing was conducted on both families, and two heterozygous mutations were identified in the TCOF1 gene: c. 1350_1351dupGG(p. A451Gfs*43) and c. 4362_4366del(p. K1457Efs*12), resulting in frameshift mutations in the amino acid sequence. Sanger sequencing validation of the TCOF1 gene in the parents of the proband in Family 1 did not detect any mutations. Proband 1 TCOF1 c. 1350_1351dupGG heterozygous variants have not been reported previously. The postoperative monosyllabic speech recognition rate of family 2 proband was 76%, the Categories of Auditory Performance(CAP) score was 6, and the Speech Intelligibility Rating(SIR) score was 4. Assessment using the Meaningful Auditory Integration Scale(MAIS) showed notable improvement in the patient's auditory perception, comprehension, and usage of hearing aids. Evaluation using the Glasgow Children's Benefit Inventory and quality of life assessment revealed significant improvements in the child's self care abilities, daily living and learning, social interactions, and psychological well being, as perceived by the parents. Conclusion:This study has elucidated the biological cause of Treacher Collins syndrome, enriched the spectrum of TCOF1 gene mutations in the Chinese population, and demonstrated that bone bridge implantation can improve the auditory and speech recognition rates in TCS patients.

In MRI examination, RF heating of implants will affect the safety of implant wearers. The conductivity of various tissues in the human body is significantly different, and the medium conductivity will affect the distribution of the RF electric field. Therefore, it is necessary to study the RF heating of different medium conductivity. Based on the analysis of the principle of MRI RF heating, this study build the model of the bird cage coil, ASTM standard phantom and lead, and the conductivity of several typical human tissues is selected as the conductivity in the experiment. Then calculate the power deposition of the lead at 64 MHz. The results show that the medium conductivity has no effect on the distribution of electric field and power deposition, and the hot spot distribution remains unchanged under different conductivity; The smaller the conductivity is, the larger the power deposition of the lead is, and the greater the temperature rise of the lead caused by RF heating is; The change of conductivity and power deposition is approximately linear. At the limit of 2 W/kg whole body specific absorption rate(SAR), the conductivity decreases, and the wire power deposition increases sharply.
ABSTRACT
Induction of cancer cell ferroptosis has been proposed as a potential treatment in several cancer types. Tumor-associated macrophages (TAMs) play a key role in promoting tumor malignant progression and therapy resistance. However, the roles and mechanisms of TAMs in regulating tumor ferroptosis is still unexplored and remains enigmatic. This study shows ferroptosis inducers has shown therapeutic outcomes in cervical cancer in vitro and in vivo. TAMs have been found to suppress cervical cancer cells ferroptosis. Mechanistically, macrophage-derived miRNA-660-5p packaged into exosomes are transported into cancer cells. In cancer cells, miRNA-660-5p attenuates ALOX15 expression to inhibit ferroptosis. Moreover, the upregulation of miRNA-660-5p in macrophages depends on autocrine IL4/IL13-activated STAT6 pathway. Importantly, in clinical cervical cancer cases, ALOX15 is negatively associated with macrophages infiltration, which also raises the possibility that macrophages reduce ALOX15 levels in cervical cancer. Moreover, both univariate and multivariate Cox analyses show ALOX15 expression is independent prognostic factor and positively associated with good prognosis in cervical cancer. Altogether, this study reveals the potential utility of targeting TAMs in ferroptosis-based treatment and ALOX15 as prognosis indicators for cervical cancer.
ABSTRACT
Abstract@#Tibet Plateau is one of the most prevalent areas of brick-tea type fluorosis in China. Effective management of brick-tea type fluorosis is a key point and a difficulty in endemic disease prevention and treatment in Tibet. Brick-tea type fluorosis is a human health concern that occurs under specific natural environments and social humanistic conditions in Tibet. Recently, the prevalence of brick-tea type fluorosis has been effectively reduced in the Tibet Plateau; however, there are still challenges for the overall brick-tea type fluorosis control, and the endemic status remains more severe than other regions endemic for brick-tea type fluorosis in China. Previous studies have shown that intake of high-fluoride brick-tea, dietary habits of drinking tea and specific natural environments are strongly associated with brick-tea type fluorosis in the Tibet Plateau. This review summarizes the advances in the epidemiological characteristics and influencing factors of brick-tea type fluorosis, so as to provide insights into the development of the long-term control strategy for brick-tea type fluorosis in the Tibet Plateau.
ABSTRACT
Objective To compare the clinical effects of interscalene brachial plexus block and superior trunk block in arthroscopic shoulder surgery with 0.25% ropivacaine. Methods 46 patients undergoing shoulder arthroscopy surgery were included and randomly divided into group ISB (n=23) and group ST (n=23). Patients in group ISB received 10 ml 0.25% ropivacaine on the lateral side of C5 and C6. Patients in group ST were treated with 5 ml 0.25% ropivacaine on both sides of the superior trunk of brachial plexus. The diaphragmatic excursion, Numerical Rating Scale(NRS), duration of the block, handgrip strength were recorded at different time. Results No statistical difference was detected between the two groups in the reduction of diaphragmatic excursion within 30 min after block (P>0.05). Compared with ISB patients, ST patients had significantly less diaphragmatic excursion at 3 h after block(P<0.05). 30 minutes after block, 8.7% patients in ISB group reached complete HDP and 52.2% patients reached partial HDP. At the same time, no complete HDP and 26.1% partial HDP were detected in ST group. 3 hours after block, patients in ST group had lower complete HDP rate (0.0% vs 17.4%) and lower partial HDP rate (39.1% vs 65.2%) than patients in ISB group. At 30 minutes and 3 h after block, the reduction of grip strength in ST group was significantly lower than that in ISB group (P<0.001). ST group had lower NRS than ISB group (P<0.05). The average block time in ISB group (8.3±1.97 )h was significantly lower than that in ST group (10.9±1.26)h (P<0.01). Conclusion Superior trunk block with 10 ml 0.25% ropivacaine is superior compared to interscalene brachial plexus block in occurrence of HDP, decrease of grip strength, postoperative pain and block duration.
ABSTRACT
ISO/TS 10974 is a general international technical specification (TS) which concentrates on the safety assessment of magnetic resonance imaging (MRI) for active implantable medical devices. ISO/TS 10974 Ed.2 was published in 2018 with substantial revision to Ed.1. To provide a guideline for adopting this recently revised TS in practice, this paper summarized the major changes and analyzed the technical improvements in Ed.2. Moreover, we also discussed current and emerging challenges to MRI safety evaluation remaining in Ed.2. The study revealed the consistency between these two editions with respect to classification of potential patient hazards and testing strategies, whereas Ed.2 has many methodological improvements over Ed.1 in testing methods for RF-induced heating, gradient-induced malfunction, and combined field testing, etc. However, it is still necessary to expand the scope of applicability and to adopt latest research findings into this TS to keep pace with the rapid developments in industry, making it a better guidance in the future.

Objective To compare the perioperative application of sufentanil and oxycodone in patients undergoing laparoscopic surgery for gastric or colorectal cancer. Methods 59 patients were selected and randomly divided into group O and group S. Anesthesia was induced with sufentanil 0.3 μg/kg in group S and oxycodone 0.3 mg/kg in group O. Anesthesia was maintained with sevoflurane balanced anesthesia. When heart rate or blood pressure reached 20% over the baseline, additional dose of oxycodone 0.1 mg/kg was given in group O and sufentanil 0.1 μg/kg in group S. 30 minutes before the end of surgery, patients in group S received sufentanil 0.1 μg/kg and group O with oxycodone 0.1 mg/kg separately. Two hours in the PACU, a rescue dose of sufentanil 0.1 μg/kg or oxycodone 0.1 mg/kg was given to the patients with VAS score bigger than 4. Hemodynamic index, VAS score, Ramsay score, adverse responses and analgesics rescue were recorded. Results No difference was found in hemodynamic index, VAS score and analgesics rescue between the two groups (P>0.05). Ramsay score of group S is lower than that of group O (P=0.014). Induction period bucking incidence in group O was obviously lower than that in group S(P=0.002). The incidence of emergency agitation in group O was significantly lower than that in group S(P=0.045).There was no significant difference in respiratory depression, postoperative nausea and vomiting between two groups (P>0.05). Conclusion Compared with sufentanil, oxycodone significantly reduced the incidence of bucking and emergency agitation. Oxycodone provided better sedation to patients who received laparoscopic surgery for gastric or colorectal cancer.
ABSTRACT
Objective To retrospectively analyze the clinical efficacy and safety of VCD (bortezomib/cyclophosphamide/dexamethason) in the treatment of multiple myeloma (MM) patients. Methods Fifty-five consecutive patients with newly diagnosed or relapsed MM were enrolled in the study retrospectively from June 2012 to June 2017. We collected and analyzed the clinical information of all patients treated with VCD.Results Firstly, the patients received therapy of VCD for median 4 cycles (Range : 2 ~8). The overall response rate (ORR) was 85.5% (45/55). The complete response/near complete response rate (CR/nCR) , very good partial response rate (VGPR) and partial response rate (PR) were 27.3%, 23.6% and 34.6%, respectively. The ORR of10 patients with renal inadequacy was 80.0%, while 45 cases with normal renal function was 82.2% (P=0.627).Secondly, with a median follow-up of 13.5 months, the median progression free survival (PFS) , the median duration of response (DOR) and the median overall survival (OS) were 27 (1~61) months, 18 (1~50) months and 49 (1~64) months, respectively. Univariate prognostic analysis showed that abnormal ISS stage Ⅲ, relapse, renal dysfunction and response inferior to VGPR were negative prognostic factors for PFS, while abnormal ISS stageⅢ and renal dysfunction were negative prognostic factors for OS. Moreover, the multivariate prognostic analysis showed that abnormal ISS stage Ⅲ and response inferior to VGPR were independent prognostic factors for PFS, while ISS stage Ⅲ was independent prognostic factors for OS. Thirdly, the VCD treatment is effective and safe.The adverse events were evaluated according to International Myeloma Working Group Uniform Response Criteria.The results showed that the most common grade 3 ~4 non-hematology adverse events (AEs) were infection (20.0%) , peripheral neuropathy (5.5%) and hypertension (5.5%). The most common grade 3~4 hematology AEs were thrombocytopenia (10.9%) , neutropenia (9.0%) and anemia (5.5%). A total of 2 patients (3.6%) discontinued VCD because of serious peripheral neuropathy and 2 cases (3.65%) died of respiratory failure because of serious infection. Conclusions The VCD regimen is effective and safe in the treatment of newly diagnosed or relapsed/refractory MM patients in China. VCD is safe in patients with renal dysfunction.
ABSTRACT
To construct a eukaryotic expression plasmid containing the luciferase reporter gene (Fluc) to quickly detect apoptosis. Four amino acids, Asp-Glu-Val-Asp (DEVD), the recognize motif of Caspase-3, were introduced into the middle of the Fluc-C and N fragment. Meanwhile, four amino acids, Asp-Glu-Val-Gly (DEVG), were selected as a negative control. Subsequently, the recombinant gene was cloned into the N and C terminal end of the split intein, and named as pFluc-DEVD and pFluc-DEVG. Then the plasmids were transfected into cells and renilla luciferase was co-transfected in each sample as an internal control for transfection efficiency. Then the apoptosis level was detected by the double luciferase reporter gene and the Western blotting analysis. The results showed that when apoptosis occurred, the content of firefly luciferase expressed in the pFluc-DEVD plasmid transfected group was about 3 times higher than pFluc-DEVG plasmid transfected group. Furthermore, Western blotting detection indicated that the Fluc level was significantly increased in pFluc-DEVD transfected group when pre-treated by apoptosis stimulants. The activation degree of Caspase-3 was closely related to the expression of Fluc, and had a significant statistical difference. These results confirmed that firefly luciferase protein expressed by pFluc-DEVD plasmid can be cleaved by the intracellular Caspase-3 enzyme, and this plasmid can accurately reflect the cell apoptosis level, which provides a useful method for quantitative detection of apoptosis.

Objective@#To analyze the morbidity, clinical characteristics, therapeutic outcomes and prognosis of cardiac lymphoma.@*Methods@#Individual patient data were obtained from pathology defined 10 cases of cardiac lymphoma from Jan 2000 to Jun 2016. The patient’s general information, clinical manifestation, pathological diagnosis, laboratory examination, cardiac involvement feature, cardiac complications, treatment, therapeutic effect and prognosis were analyzed.@*Results@#Of 3 918 cases of lymphoma patients, 10 cases of cardiac involvement were identified, including primary cardiac lymphoma (PCL) in 1 case, secondary cardiac lymphoma (SCL) in 9 cases. Of the 10 patients in our analysis, the male-to-female ratio was 3∶2, with a median age of 55 (19-88) years old. The most presenting complaints were dyspnea in 7 cases, followed by chest pain in 5 cases, fatigue in 2 patients and edema in 2 cases. Pathological types included diffuse large B cell lymphoma (DLBCL) in 7 cases, T cell lymphoma (T-LBL) in 1 case, Hodgkin’s lymphoma (HL) in 1 case, and Burkitt lymphoma (BL) in 1 case. The sites of the heart affected by lymphoma in the PCL patient were right and left atriums with multiple nodules; and for SCL, the sites were mainly pericardium associated with a pericardial effusion in 5 cases, a pericardial mass in 2 cases. Congestive heart failure affects 7 patients and cardiac arrhythmias were identified in 4 cases mainly sinus tachycardia, atrial fibrillation and atrioventricular block. Except one untreated because of old age and poor performance, the rest of 9 patients were treated by either chemotherapy in 4 cases or chemotherapy combined radiotherapy (including the extracardiac sites) in 5 patients. With the median follow-up of 9 months, the one PCL patient achieved partial response (PR) , progress free survival (PFS) for 6 months and the overall survival (OS) for 21 months; in the cohort of 6 SCL patients cardiac involved at diagnosis, complete response (CR) was achieved in 1 case (16.7%) , PR in 3 cases, progressing disease (PD) in 2 cases, with the median PFS for 5 months and the median OS for 19 months; and for the other 3 SCL patients cardiac involved at progression, PR was achieved in 2 case and death in 1 case, with the median PFS for 4 months and the median OS unavailable because of censored data.@*Conclusion@#Cardiac lymphoma represents a rare subset of lymphoma, the most common type is DLBCL, and the main clinical manifestations are dyspnea and chest pain, always combined by arrhythmia and congestive heart failure. The main therapeutic regimen for cardiac lymphoma includes combined chemotherapy and the prognosis for patients with either PCL or SCL is usually poor.
