ABSTRACT

OBJECTIVE@#To explore the mechanism of electroacupuncture (EA) in promoting recovery of the facial function with the involvement of autophagy, glial cell line-derived neurotrophic factor (GDNF), and phosphatidylinositol-3-kinase (PI3K)/mammalian target of rapamycin (mTOR) signaling pathway.@*METHODS@#Seventy-two male Sprague-Dawley rats were randomly allocated into the control, sham-operated, facial nerve injury (FNI), EA, EA+3-methyladenine (3-MA), and EA+GDNF antagonist groups using a random number table, with 12 rats in each group. An FNI rat model was established with facial nerve crushing method. EA intervention was conducted at Dicang (ST 4), Jiache (ST 6), Yifeng (SJ 17), and Hegu (LI 4) acupoints for 2 weeks. The Simone's 10-Point Scale was utilized to monitor the recovery of facial function. The histopathological evaluation of facial nerves was performed using hematoxylin-eosin (HE) staining. The levels of Beclin-1, light chain 3 (LC3), and P62 were detected by immunohistochemistry (IHC), immunofluorescence, and reverse transcription-polymerase chain reaction, respectively. Additionally, IHC was also used to detect the levels of GDNF, Rai, PI3K, and mTOR.@*RESULTS@#The facial functional scores were significantly increased in the EA group than the FNI group (P<0.05 or P<0.01). HE staining showed nerve axons and myelin sheaths, which were destroyed immediately after the injury, were recovered with EA treatment. The expressions of Beclin-1 and LC3 were significantly elevated and the expression of P62 was markedly reduced in FNI rats (P<0.01); however, EA treatment reversed these abnormal changes (P<0.01). Meanwhile, EA stimulation significantly increased the levels of GDNF, Rai, PI3K, and mTOR (P<0.01). After exogenous administration with autophagy inhibitor 3-MA or GDNF antagonist, the repair effect of EA on facial function was attenuated (P<0.05 or P<0.01).@*CONCLUSIONS@#EA could promote the recovery of facial function and repair the facial nerve damages in a rat model of FNI. EA may exert this neuroreparative effect through mediating the release of GDNF, activating the PI3K/mTOR signaling pathway, and further regulating the autophagy of facial nerves.

ABSTRACT

Objective:Immune checkpoint inhibitors have a high remission rate in the preoperative application of resectable and potentially resectable non-small cell lung cancer when combined with chemotherapy. For the unresectable stage Ⅲ non-small cell lung cancer, whether the transformation can be achieved through this regimen to provide opportunities for surgical resection is controversial. In this study, we evaluated the pattern of transformation therapy by reviewing the efficacy and safety of preoperative therapy and surgery of this group.Methods:A review of 23 patients undergoing surgical resection after transformation therapy by preoperative immunotherapy combined chemotherapy between November 2019 and November 2021 was performed. All patients must clarify the pathological diagnosis of non-small cell lung cancer by biopsy. After the multi-disciplinary treatment team and preoperative imaging assessment, the diagnosis should be consistent with unresectable stage III as described in the Expert Consensus on Multidisciplinary Management of Stage Ⅲ Non-Small Cell Lung Cancer, 2019 Edition. After 2 to 4 cycles of preoperative anti-PD-1 monoclonal antibody combined with chemotherapy, the surgical team assessed the chance of resection and performed surgery. Important indicators such as surgical resection rate, R0 resection rate, MPR, pCR, incidence of grade 3-5 adverse reactions and various other perioperative data were counted.Results:In the whole group, initial imaging evaluation was 10 of stage cⅢA and 13 of stage cⅢB.15 cases had multiple stations N2 lymph nodes metastasis, 9 had enlarged fused N2 lymph nodes metastasis, 6 had large vessel invasion(T4), and 1 had contralateral mediastinal lymph node metastasis(N3). After preoperative neoadjuvant therapy, 17 cases achieved PR, 3 achieved SD and 3 achieved PD. The surgical resection rate of the whole group was 91.3%(21/23, 1 lobectomy combined with superior vena cava reconstruction, 2 sleeve lobectomy, 5 pneumonectomy, 12 lobectomy/combined lobectomy, 1 wedge resection and 2 unresectable cases), R0 resection rate was 95.2%(20/21). MPR was achieved in 13 cases, 8 of them reached pCR. There were no perioperative deaths, median surgical time was 260(190-460) min, median bleeding volume was 100(50-750) ml, median drainage time was 5(3-9) days, and median hospitalization was 7(5-11) days. Two cases got immunotherapy-related grade 3 adverse reactions, one was interstitial pneumonia and the other was immune-related injury involving the eye, oral and genital mucosa. Two cases got surgical complications and one was persistent lung leakage, which stopped after 46 days of conservative treatment; The other was pleural effusion, which was relieved after drainage.Conclusion:For the unresectable stage Ⅲ NSCLC, immunotherapy combined chemotherapy is an effective preoperative downstage method. It can convert 91.3% cases to resectable ones while achieving a good degree of pathological remission. Its side reactions are generally controllable and safety.

ABSTRACT

At present, the routine specialized training for primary pediatricians (focusing on theoretical learning of public subjects) cannot meet the needs of primary pediatricians. In order to promote the development of children's medical care at the grassroots level and improve the quality, medical and clinical research abilities of regional pediatric medical personnel, the Children's Hospital of Chongqing Medical University has designed and built a "hierarchical training model for improving the professional ability of pediatricians" from the aspects of training objectives, training contents, training methods, construction and evaluation of training programs, and quality control. In addition, the 8-month "Pediatric Professional Basic Training" and the 9-month "Pediatric Professional Ability Improvement Training" were respectively carried out in Xianyang Children's Hospital. In the "Professional Basic Training", 88 trainees were comprehensively evaluated after training, 53 of whom were qualified or above. In the "Ability Improvement Training", 26 of the 29 students actually participated in the evaluation and reached the qualified level or above. Learners provided feedbacks that they have effectively improved their own knowledge structure, expanded their clinical diagnosis and treatment thinking and clinical research ideas, and provided some guidance for clinical work.

ABSTRACT

@#Abstract:Objective To evaluate the basic development status of public health emergencies of infectious diseases in Hainan Province from 2013 to 2022, analyze the distribution and characteristics of these emergencies, as to provide important scientific basis for the study and formulation of economic health development planning policies, for the health security policies and infectious disease prevention and control strategies in Hainan Province. Methods The relevant statistical data of public health emergencies involving infectious diseases reported in Hainan Province from 2013 to 2022 were collected, and the status quo of these emergencies was analyzed by using descriptive data statistical analysis method. The ARIMA model was used to predict the number of public health emergencies reported by infectious diseases in Hainan Province from 2023 to 2025. Results From 2013 to 2022, a total of 482 public health emergencies were reported in Hainan Province, of which 426 were infectious disease public health emergencies, accounting for 88.38%, with a total of 8 876 cases, an incidence rate of 0.61%, and eight deaths, a case fatality rate of 0.09%. The major public health emergencies of infectious diseases were unclassified events and general events, accounting for 69.25% and 29.58%, respectively. The main diseases were novel coronavirus infection, chickenpox and hand, foot and mouth disease, accounting for 45.07%, 15.49% and 11.97%, respectively; in terms of time distribution, the number of reported incidents showed an upward trend over time, with a decline in 2021, and mainly had three peak periods, April, August and December, with a total of 220 cases reported; in terms of regional distribution, the major cities and counties reported were Haikou, Wanning and Wenchang, accounting for 27.46%, 19.25% and 9.86%, respectively; in terms of location distribution, the events mainly occurred in schools, accounting for 42.02% of the total number of incidents. The ARIMA(1, 1, 0) model was used to predict infectious disease public health emergencies, and the results showed that the forecast state would be stable from 2023 to 2025, with no obvious upward trend, that is, the fluctuation range of public health emergencies related to infectious diseases in Hainan Province would be stable in the next three years. Conclusion The number of infectious disease public health emergencies reported in Hainan Province from 2013 to 2022 has increased year by year, with a decline in 2021. Although the forecast shows that public health emergencies such as infectious diseases are relatively stable with no obvious upward trend, the prevention and control of the epidemic should not be taken lightly. Hainan Province should continue to increase the investment in monitoring public health emergencies, improve the information system of public disease prevention and control, and carry out real-time monitoring of public health emergencies of infectious diseases.

ABSTRACT

Objective: To investigate the etiology, complications, and prognostic factors of stage 5 chronic kidney disease (CKD5) in children. Methods: A case series study was conducted to retrospectively analyze the general situation, clinical manifestations, laboratory tests, genetic testing, and follow-up data (until October 2022) of 174 children with CKD5 who were diagnosed and hospitalized at the Children's Hospital of Chongqing Medical University from April 2012 to April 2021. The characteristics of complications in the children were compared based on age, gender, and etiology. Based on the presence or absence of left ventricular hypertrophy (LVH), patients were divided into LVH group and non LVH group for analyzing the influencing factors of cardiovascular disease. Patients were also divided into death group and survival group, peritoneal dialysis group and hemodialysis group based on the follow-up data for analyzing the prognostic factors. The chi-square test, independent sample t-test, Fisher exact probability test, Mann-Whitney U test and Kruskal Wallis test were used to analyze data among different groups. Multivariate Logistic regression analysis was used to identify the prognostic factors. Results: A total of 174 children with CKD5 were enrolled in the study (96 boys and 78 girls), aged 11.2 (8.2, 13.0) years. Congenital kidney and urinary tract malformations (CAKUT) were the most common causes of the CKD5 (84 cases, 48.3%), followed by glomerular diseases (83 cases, 47.7%), and among which 28 cases (16.1%) were hereditary glomerular diseases. The common complications of CKD5 included anemia (98.2%, 165/168), mineral and bone disorder in chronic kidney disease (CKD-MBD) (97.7%, 170/174), lipid metabolism disorders (87.5%, 63/72), hypertension (81.4%, 127/156) and LVH (57.6%,57/99). The incidences of hypertension in primary glomerular disease were higher than that in CAKUT(93.8%(30/32) vs.73.7%(56/76),χ2=5.59,P<0.05). The incidences of hypertension in secondary glomerular disease were higher than that in CAKUT and that in hereditary kidney disease (100.0%(20/20) vs. 73.7%(56/76), 68.2%(15/22), both P<0.05). The incidence of hypocalcemia in CAKUT, primary glomerular disease, and hereditary kidney disease was higher than that in secondary glomerular disease (82.1%(69/84), 88.2%(30/34), 89.3%(25/28) vs. 47.6%(10/21), χ2=10.21, 10.75, 10.80, all P=0.001); the incidence of secondary hyperparathyroidism in women was higher than that in men (80.0%(64/80) vs. 95.0%(57/60), χ2=6.58, P=0.010). The incidence of LVH in children aged 6-<12 was higher than that in children aged 12-18 (73.5%(25/34) vs. 43.1%(22/51), χ2=7.62, P=0.006). Among 113 follow-up children, the mortality rate was 39.8% (45/113). Compared to the survival group, the children in the death group had lower hemoglobin, higher blood pressure, lower albumin, lower alkaline phosphatase and higher left ventricular mass index ((67±19) vs. (75±20) g/L, 142 (126, 154) vs. 128(113, 145) mmHg(1 mmHg=0.133 kPa), (91±21) vs. (82±22) mmHg, 32 (26, 41) vs. 40 (31, 43) g/L, 151 (82, 214) vs. 215 (129, 37) U/L, 48 (38, 66) vs. 38(32, 50) g/m2.7,t=2.03, Z=2.89, t=2.70, Z=2.49, 2.79, 2.29,all P<0.05), but no independent risk factors were identified (all P>0.05). The peritoneal dialysis group had better alleviation for anemia, low calcium, and high phosphorus than the hemodialysis group ((87±22) vs. (72±16) g/L, (1.9±0.5) vs. (1.7±0.4) mmol/L, (2.2±0.7) vs. (2.8±0.9) mmol/L, t=2.92, 2.29, 2.82, all P<0.05), and the survival rate of the peritoneal dialysis group was significantly higher than that of the hemodialysis group (77.8% (28/36) vs. 48.4% (30/62), χ2=8.14, P=0.004). Conclusions: CAKUT is the most common etiology in children with CKD 5, and anemia is the most common complication. The incidence of complications in children with CKD 5 varies with age, gender and etiology. Anemia, hypertension, hypoalbuminemia, reduced alkaline phosphatase and elevated LVMI may be the prognostic factors in children with CKD5. Peritoneal dialysis may be more beneficial for improving the long-term survival rate.

ABSTRACT

Objective To explore the predictive value of preoperative alkaline phosphatase to prealbumin ratio (APR) in prognosis and postoperative complications for patients with hepatocellular carcinoma (HCC) after radical tumor resection. Methods A total of 217 HCC patients who underwent radical tumor resection in the Department of Hepatobiliary Surgery of the Affiliated Hospital of Southwest Medical University from January 2013 to August 2021 were retrospectively recruited and their clinical data were statistically analyzed. The X-tile software was used to obtain the optimal cutoff value of APR. The χ 2 test was conducted to analyze association between preoperative APR and other clinicopathological characteristics. The Kaplan-Meier curve was plotted and the Log-rank test was performed to analyze survival of patients. The univariate and multivariate Cox proportional hazards regression models were used to analysis factors affecting the prognosis of HCC patients. The univariate analysis and multivariate Logistic regression were used to identify factors related with postoperative complications. The receiver operating characteristic (ROC) curve was used to determine the predicting value of APR. Results The optimal cutoff value for APR ratio was 0.5 and these 217 patients were divided into the low- and high APR groups (111 vs 106 cases) accordingly. Compared with the low-APR group, the proportion of patients with ALT (> 50 U/L), Alb (< 40 g/L), the CNLC of the III stage, open surgery, liver cirrhosis, multiple tumor lesions, postoperative complication, and major complication were significantly increased in the high-APR patients (all P < 0.05). Moreover, the 1-, 3-, and 5-year OS were 86.0%, 74.9%, and 71.3%, respectively in the low-APR patients, while the numbers were 79.2%, 57.5%, and 47.0%, respectively, in the high-APR patients, indicating that patients in high-APR group had significantly worse OS ( P =0.002). AFP ( HR =1.774, 95% CI : 1.107-2.843, P =0.017), CNLC stage ( HR =2.708, 95% CI : 1.514-4.844, P =0.001), tumor size ( HR =1.696, 95% CI : 1.060-2.714, P =0.028), and APR ( HR =2.022, 95% CI : 1.244-3.285, P =0.004) were all independent risk predictors for OS. The 1-, 3-, and 5-year RFS were 82.3%, 69.4%, and 61.3%, respectively, in the low-APR patients, whereas the numbers were 76.2%, 54.4%, and 44.2%, respectively in the high-APR patients, suggesting that high-APR patients had significantly worse recurrence-free survival ( P =0.016). The CNLC stage ( HR =2.509, 95% CI : 1.423-4.422, P =0.001), tumor size ( HR =1.725, 95% CI : 1.119-2.660, P =0.014), and APR ( HR =1.619: 95% CI : 1.037-2.527, P =0.034) were all independent FRS predictors. Hypertension ( OR =3.09, 95% CI : 1.385-6.893, P =0.006), open surgery ( OR =4.198, 95% CI : 1.779-9.907, P =0.001), liver cirrhosis ( OR =2.376, 95% CI : 1.194-4.729, P =0.014), and APR ( OR =2.151, 95% CI : 1.160-3.986, P =0.015) were all independent risk predictors for the postoperative major complications. The AUC for APR, ALP, a nd PA in predicting the major complications was 0.625 (95% CI : 0.547-0.702), 0.613 (95% CI : 0.534-0.693), and 0.554 (0.474-0.634). Conclusion Preoperative APR could be used to predict prognosis and postoperative major complications of HCC patients after radical tumor resection.

ABSTRACT

OBJECTIVE@#To observe the effects of electroacupuncture at "Siguan" points on behavior, colonic 5-hydroxytryptamine (5-HT) and fecal short-chain fatty acids (SCFAs) in rats with post-stroke depression (PSD), and explore the effect mechanism of electroacupuncture at Siguan points on PSD.@*METHODS@#Fifty SD rats were randomly divided into a sham-operation group, a stroke group, a PSD group, a drug group and an electroacupuncture group, with 10 rats in each one. The stroke model was established by middle cerebral artery occlusion (MCAO) method in the stroke group; except for the sham-operation group, the rats in the other groups were intervened with MCAO combined with solitary and chronic unpredictable mild stress (CUMS) to establish PSD model. In the electroacupuncture group, electroacupuncture was delivered at "Hegu" (LI 4) and "Taichong" (LR 3), with disperse-dense wave, 2 Hz/10 Hz in frequency, for 30 min in each intervention, once daily, for consecutive 21 days. Simultaneously, distilled water (0.01 L•kg-1•d-1) was administrated intragastrically. Fluoxetine solution (2.33 mg•kg-1•d-1) was given by gavage , once a day and for 21 days in the drug group. The same procedure of fixation and gavage with distilled water were adopted in the sham-operation group, the stroke group and the PSD group. Separately, before stroke modeling, after PSD modeling and after 21-day intervention, the consumption of sugar water and the scores of horizontal movement and vertical movement in open-field test were observed. After 21-day intervention, the content of colonic 5-HT was detected by immunohistochemical method, and that of fecal SCFAs was determined by gas chromatography mass spectrometry.@*RESULTS@#After PSD modeling, compared with the stroke group, the sugar water consumption, the horizontal movement scores and vertical movement scores of the open-field test were all reduced in the PSD group, the drug group and the electroacupuncture group (P<0.05). After 21-day intervention, the sugar water consumption and the scores of horizontal movement and vertical movement of the open-field test were increased in the drug group and the electroacupuncture group (P<0.05) when compared with the PSD group; and the horizontal movement score in the electroacupuncture group was lower than that of the drug group (P<0.05). Compared with the sham-operation group, the contents of total fecal SCFAs and acetic acid were lower in the stroke group (P<0.05), and the contents of colonic 5-HT and total fecal SCFAs, acetic acid, propionic acid and butyric acid were reduced in the PSD group (P<0.05). In comparison with the PSD group, the contents of colonic 5-HT and total fecal SCFAs, acetic acid and propionic acid were increased in the drug group and the electroacupuncture group (P<0.05); and the content of colonic 5-HT in the electroacupuncture group was lower than that of the drug group (P<0.05). The level of colonic 5-HT was positively correlated with the contents of total fecal SCFAs and propionic acid (r=0.424, P=0.005; r=0.427, P=0.004).@*CONCLUSION@#Electroacupuncture at "Siguan" points can relieve the depression-like behavior of PSD rats, and its underlying mechanism may be related to the regulation of fecal SCFAs, which affects the release of colonic 5-HT.

ABSTRACT

The morbidity and mortality of lung cancer are always at the forefront of malignant tumors. To improve the therapeutic effects and overall survival of lung cancer patients is one of the key areas both in clinical medicine and basic research. With the development of precision medicine, targeted treatment based on the characteristics of DNA mutation and immunotherapy targeting PD-1/PD-L1, CTLA-4 and other pathways have promoted the progress of the overall diagnosis and treatment level of lung cancer, which has been widely used in clinical practice. While making the continuous achievements in the above fields, the researchers committed to lung cancer research are gradually shifting their attention to the exploration of RNA level. Some results have been accumulated in the effects of RNA epigenetic modifications on the biological behavior of lung cancer. N6-methyladenosine(m6A) is the most abundant form of mRNA methylation. The dysfunction of m6A modification mediated by related regulatory proteins has been reported to play an important role in the development and progression of lung cancer. This paper focuses on the detection methods of m6A modification, related regulatory proteins and their mode of action, and reviews the effects on the onset, diagnosis, treatment and prognosis of lung cancer. The aim is not only to summarize the researchers' latest understanding of the epigenetic regulatory mechanism, but also to provide new perspectives for the early diagnosis, effective drug use and prognosis judgment of lung cancer.

ABSTRACT

Objective: To understand the current situation regarding pediatric off-label use of drugs recommendations in Chinese clinical practice guidelines and to make recommendations for standardized reporting format regarding off-label use of drugs for children. Methods: This cross-sectional study was carried out by systematically searching the databases for Chinese guideline consensus articles published in journals between 2018 and 2020 and extracting recommendations regarding off-label use of drugs from those articles. The essential characteristics of the included guidelines, the ranking of off-label drug types, the order of drug information, the type of off-label drug use, and the percentage of citation studies on which the recommendations were based were analyzed. Results: Among 108 studies that included Chinese off-label guidelines and consensus, 364 recommendations on pediatric off-label use of drugs were included. The Chinese Medical Association published the most, 48 out of the 108 studies (44.4%), and of those 14 studies (13.0%) were on infectious and parasitic diseases. Of the 364 recommendations on off-label use of drugs, the most commonly addressed drugs were 16 recommendations (4.4%) for cyclosporine A, 11 recommendations (3.0%) for methotrexate , and 11 recommendations (3.0%) for fentanyl. The most commonly addressed drug categories were as follows: 68 recommendations (18.6%) were immune system drugs, 66 recommendations (18.1%) were anti-infectives, and 56 recommendations (15.4%) were oncology drugs. The most commonly addressed drug information accounts were as follows: 364 recommendations (100.0%) were indications, 204 recommendations (56.0%) were dosages, and 198 recommendations (54.4%) were the route of administration. Based on the instructions approved by the Chinese Food and Drug Administration, the main forms of the off-label drug were as follows: 175 recommendations (48.1%) were unapproved indications, 127 recommendations (34.9%) were unapproved populations, and 72 recommendations (19.8%) were unapproved ages. Only 129 recommendations (35.4%) were cited, mainly including clinical guidelines (48 studies, 23.4%), reviews (22 studies, 10.7%), and pediatric randomized controlled trials (22 studies, 10.7%). Conclusions: Off-label use of drugs is commonly recommended in pediatric guidelines and consensus documents written by Chinese authors. However, the reporting of the recommendations varies widely, and the quality of the supporting evidence is poor.

ABSTRACT

Objective: To evaluate the indications, safety, feasibility, and surgical technique for patients with head and neck cancers undergoing transoral robotic retropharyngeal lymph node (RPLN) dissection. Methods: The current study enrolled 12 consecutive head and neck cancer patients (seven males and four females) who underwent transoral robotic RPLN dissection with the da Vinci surgical robotic system at the Sun Yat-sen University Cancer Center from May 2019 to July 2020. Seven patients were diagnosed as nasopharyngeal carcinoma with RPLN metastasis after initial treatments, 4 patients were diagnosed as thyroid carcinoma with RPLN metastasis after initial treatments, and one patient was diagnosed as oropharyngeal carcinoma with RPLN metastasis before initial treatments. The operation procedure and duration time, intraoperative blood loss volume and complications, nasogastric feeding tube dependence, tracheostomy dependence, postoperative complications, and hospitalization time were recorded and analyzed. Results: All patients were successfully treated by transoral robotic dissection of the metastatic RPLNs, none of which was converted to open surgery. RPLNs were completely resected in 10 patients, and partly resected in 2 patients (both were nasopharyngeal carcinoma patients). The mean number of RPLN dissected was 1.7. The operation duration time and intraoperative blood loss volume were (191.3±101.1) min and (150.0±86.6) ml, respectively. There was no severe intraoperative complication such as massive haemorrhage or adjacent organ injury during surgery. Nasogastric tube use was required in all patients with (17.1±10.6) days of dependence, while tracheotomy was performed in 8 patients with (11.6±10.7) days of dependence. The postoperative hospitalization stay was (8.5±5.7) days. Postoperative complications occurred in 4 patients, including 2 of retropharyngeal incision and 2 of dysphagia. During a follow-up of (6.5±5.1) months, disease-free progression was observed in all patients, 10 patients were disease-free survival and other 2 patients were survival with tumor burden. Conclusions: The transoral robotic RPLN dissection is safety and feasible. Compared with the traditional open surgical approach, it is less traumatic and safer, has fewer complications and good clinical application potentiality. The indications for transoral robotic RPLN dissection include thyroid carcinoma, oropharyngeal carcinoma, and some selected nasopharyngeal carcinoma and other head and neck cancers. Metastatic RPLNs from some nasopharyngeal carcinoma with incomplete capsule, unclear border and adhesion to the surrounding vessels are not suitable for transoral robotic RPLN dissection.

ABSTRACT

Long non-coding RNA KCNQ1OT1 is highly expressed in a variety of tumors, but there are few studies in gastric cancer and the results are inconsistent. The relevant research of its specific mechanism in gastric cancer is also scarce. Through the analysis of several TCGA public databases, we found that KCNQ1OT1 was generally highly expressed in gastric cancer, and the prognosis of gastric cancer patients with a high expression of KCNQ1OT1 was poor. The expression of KCNQ1OT1 is closely related to many clinical factors of gastric cancer, especially the mutation of TP53, and its expression is significantly related to immune cell infiltration. KCNQ1OT1 is generally highly expressed in gastric cancer cell lines. Knockdown of KCNQ1OT1 can inhibit the proliferation of gastric cancer cell lines. Co- expression network analysis showed that its expression was closely related to tumor metabolism. Glutaminase 1 (GLS1) is generally highly expressed in gastric cancer, which is closely related to a poor prognosis. There is a significant correlation between the expression of KCNQ1OT1 and GLS1. Knockdown of KCNQ1OT1 can inhibit the expression of GLS1 mRNA, and overexpression of GLS1 can partially rescue the proliferation of gastric cancer cells caused by knockdown of KCNQ1OT1. Therefore, we speculate that KCNQ1OT1 may regulate the growth of gastric cancer cells through GLS1. Our study explored the role of KCNQ1OT1 in gastric cancer through bioinformatics database and experiments, suggesting that KCNQ1OT1 may promote the development of gastric cancer by regulating glutamine metabolism, which provides a new target for the clinical research on targeted treatment in gastric cancer.

ABSTRACT

Objective: To explore the therapeutic effects of transoral robotic surgery (TORS) and traditional surgical modes in oropharyngeal squamous cell carcinoma (OPSCC). Methods: The clinicopathological data of patients with oropharyngeal squamous cell carcinoma treated at Sun Yat-sen University Cancer Center from 2010 to 2018 were retrospectively analyzed. 135 cases were treated with traditional surgery (non-TORS group), while 52 cases were treated with TORS (TORS group). The prognosis of the two groups of patients were analyzed by Kaplan-Meier method and Log rank test, the influencing factors were analyzed by Cox regression model. Results: The 2-year overall survival (OS, 94.2%) and 2-year progression-free survival (PFS, 93.8%) of patients in the TORS group were better than those in the non-TORS group (71.4% and 71.4%, respectively, P<0.05). The 2-year OS (93.3%) and 2-year PFS (92.8%) of TORS group patients in T1-2 stage were better than those of non-TORS group (73.1% and 72.8%, respectively, P<0.05). The 2-year OS (95.8%) and 2-year PFS (95.2%) of patients with stage Ⅰ to Ⅱ in the TORS group were not significantly different from those in the non-TORS group (84.1% and 83.9%, respectively, P>0.05). The 2-year OS (92.9%) and 2-year PFS rate (92.7%) of patients with stage Ⅲ to Ⅳ in the TORS group were better than those in the non-TORS group (64.7% and 63.9%, respectively, P<0.05). The 2-year OS (94.4%) of HPV-positive patients in the TORS group was not significantly different from that in the non-TORS group (83.3%, P=0.222). The 2-year OS of HPV-negative patients in the TORS group (94.1%) was significantly different from that in the non-TORS group (43.7%, P<0.001). HPV status was an independent prognostic factor (P=0.008). Conclusions: TORS has a better prognosis in the treatment of oropharyngeal squamous cell carcinoma compared with the traditional treatment methods. The patients with T1-T2 can achieve better survival benefits after TORS treatment. The HPV-positive OPSCC patients has a better prognosis than that of HPV-negative OPSCC patients, and regardless of HPV status, OPSCC patients in the TORS group could obtain a better survival prognosis.

ABSTRACT

Primary nephrotic syndrome (PNS) is one of the most common glomerular diseases in children.Steroid-resistant nephrotic syndrome (SRNS) is defined as no remission of nephrotic syndrome after daily Prednisone treatment at an adequate oral dose for 4 weeks, which is classified as idiopathic SRNS and inherited SRNS according to the presence or absence of monogenic disorder.At present, steroid combined with calcineurin inhibitor (CNI) is preferred to idiopathic SRNS, and 50%-70% of children can achieve complete or partial remission.A small proportion of children with idiopathic SRNS and the majority of inherited SRNS may be resistant to different immunosuppressive agents with two different mechanisms, including CNI.They, unfortunately, gradually progress to end-stage renal disease within 5-10 years.In this paper, the therapeutic advances and future prospects in pediatric SRNS are reviewed.

ABSTRACT

Objective To investigate the current distribution of ticks and predict the suitable habitats of ticks in the Yangtze River Delta urban agglomeration in 2017, so as to provide insights into tick control and management of tick-borne diseases in these areas. Methods All publications pertaining to tick and pathogen distribution in the Yangtze River Delta urban agglomeration were retrieved, and the geographical location of tick distribution was extracted. The effects of 19 climatic factors on the distribution of ticks were examined using the jackknife method, including the mean temperature of the wettest quarter, precipitation of the coldest quarter, mean temperature of the driest quarter, maximum temperature of the warmest month, precipitation of the driest month, minimal temperature of the coldest month, annual precipitation, mean daily temperature range, precipitation seasonality, annual temperature range, temperature seasonality, annual mean temperature, mean temperature of the warmest quarter, precipitation of the wettest quarter, isothermality, mean temperature of the coldest quarter, precipitation of the wettest month, precipitation of the driest quarter and precipitation of the warmest quarter. The distribution of ticks was analyzed in 2020 using the maximum entropy (MaxEnt) model, and the potential suitable habitats of ticks were predicted in 2070 using the MaxEnt model based on climatic data. Results A total of 380 Chinese and English literatures were retrieved, and 148 tick distribution sites were extracted, with 135 sites included in the subsequent analysis. There were 7 genera (Haemaphysalis, Rhipicephalus, Ixodes, Dermacentor, Boophilus, Hyalomma and Amblyomma) and 27 species of ticks detected in the Yangtze River Delta urban agglomeration. The climatic factors affecting the distribution of ticks in the Yangtze River Delta urban agglomeration mainly included the mean temperature of the wettest quarter and the precipitation of the coldest quarter, with 26.1% and 23.6% contributions to tick distributions. The high-, medium- and low-suitable habitats of ticks were 20 337.08, 40 017.38 km2 and 74 931.43 km2 in the Yangtze River Delta urban agglomeration in 2020, respectively. The climate changes led to south expansion of the suitable habitats of ticks in the Yangtze River Delta urban agglomeration in 2070, and the total areas of suitable habitats of ticks was predicted to increase by 18 100 km2. In addition, the high-, medium- and low-suitable habitats of ticks were predicted to increase to 24 317.84, 45 283.02 km2 and 83 766.38 km2 in the Yangtze River Delta urban agglomeration in 2070, respectively. Conclusions Multiple tick species are widespread in the Yangtze River Delta urban agglomeration, and the future climate changes may lead to expansion of tick distribution in these areas.

ABSTRACT

Bromodomain-containing protein 4 (BRD4) is one of the most important members in the bromodomain and extra terminal domain(BET) family, it plays an important role in cellular physiology in human body, such as cell cycles, cell proliferation, and immune response. Recent studies have shown that BRD4 is associated with occurrence and development of acute myeloblastic leukemia, multiple myeloma and lymphoma. The mechanisms of BRD4 in hematologic malignancies including the regulation of c-Myc expression, and participation of the composition of super-enhancer, etc. At present, many kinds of inhibitors have been developed to target inhibit BRD4 for therapy in hematologic malignancies, and some of BRD4 inhibitors have entered phase Ⅱ clinical trials, which suggested that BRD4 inhibitors are expected to become new therapeutic agents for hematologic malignancies. In this review, the research advance of BRD4 and BRD4 inhibitors in hematologic malignancies was summarized briefly.

ABSTRACT

Objective: To evaluate the safety, efficacy and feasibility of transoral robotic surgery (TORS) for parapharyngeal space (PPS) neoplasms. Methods: We collected data from 7 patients with PPS neoplasm who received TORS in Sun Yat-sen University Cancer Center between May 2017 and November 2020, and patients' clinical and pathological characteristics were analysed. There were 2 men and 5 women with age ranged from 35 to 76 years. Among them, 2 patients underwent secondary surgery, 2 patients required combined transcervical approach to complete surgery, and 1 patient was suspected of ipsilateral cervical lymph node metastasis and scheduled for diagnostic TORS. The preoperative tumor size, operation time, intraoperative blood loss, postoperative bleeding, dyspnea, neurological impairment, feeding time and postoperative hospital stay were analyzed. SPSS 24.0 was used to analyze the data. Results: TORS was performed successfully with complete removal of tumors in all 7 cases. Among 6 patients with curative TORS, 5 patients received TORS with postoperative diagnoses of neurogenic tumors and 1 patient underwent TORS combined transcervical approach with postoperative disgnosis of recurrent pleomorphic adenoma; no intraoperative tumor rupture occurred; the intraoperative blood loss was 20-200 ml with a median of 40 ml; the operation time was 65.0-238.0 min with a median of 77.5 min; the oral feeding time was 3-6 days with a median of 3 days; and the postoperative hospital stay was 4.2±1.6 days. One patient presented with neck swelling 3 days after surgery, but this symptom relieved 3 days later after treatments with antibiotic, hemostasis and detumescence. One patient received diagnostic TORS, as intraoperative pathology indicating a recurrent pleomorphic adenoma, then the neoplasm got completely resected through transcervical-transparotid approach. None of 7 patients manifested with airway obstruction, bleeding or nerve injury symptoms after operation. All patients were followed for 2 to 44 months, no local recurrence or distant metastasis was found. Conclusions: TORS is a safe, effective and feasible treatment for selected PPS neoplasms, with less cosmetic impact, less trauma and blood loss, few postoperative complications, enhanced postoperative recovery and short hospital stay.

ABSTRACT

Objective:To explore the relationship between the vitamin D receptor ApaⅠ and BsmⅠ gene polymorphisms and the risk of benign paroxysmal positional vertigo(BPPV).Methods:The 98 patients with BPPV admitted to the Neurology Clinic of our hospital from March 2020 to March 2021 were selected as vertigo group, and 100 healthy individuals were selected as a healthy control group.The gene polymorphism of ApaⅠ(rs7975232)and Bsm Ⅰ(rs1544410)were detected by polymerase chain reaction-based restriction fragment length polymorphism(PCR-RFLP). Binary Logistic regression was used to analyze the influencing factors of benign paroxysmal positional vertigo.Results:The serum levels of total cholesterol and uric acid were significantly higher in the BPPV group than in a healthy control group( P<0.05). The actual and predicted values of the ApaⅠ and BsmⅠ gene distribution were compared between the BPPV group and a healthy control group, and the difference was not statistically significant( P>0.05). The ApaⅠ and BsmⅠ genotypes of the BPPV group and the control group were stable and consistent with the Hardy-Weinberg equilibrium law.The ApaⅠ gene rs7975232 and the BsmⅠ gene rs1544410 genotype and allele frequency distribution[n(%)]showed statistically significant difference(all P<0.05)between control vs BPPV groups.The locus genotype and allele frequency distribution[n(%)]showed statistically significant difference between control vs BPPV group( P<0.05). The total cholesterol, blood uric acid, rs7975232CC, rs7975232AA, rs1544410 CC, and rs1544410 CT were risk factors for the occurrence of benign paroxysmal positional vertigo. Conclusions:Gentic polymorphisms at the cleavage sites of restriction endonuclease of vitamin D gene ApaⅠ rs7975232 and BsmⅠ gene rs1544410 have certain correlation with the occurrence of(BPPV)disease.Population with type CC and AA in ApaI rs7975232 and type CC and CT in BsmⅠ rs1544410 are more prone to BPPV.
