RESUMEN
Hearing loss has become increasingly prevalent and causes considerable disability, thus gravely burdening the global economy. Irreversible loss of hair cells is a main cause of sensorineural hearing loss, and currently, the only relatively effective clinical treatments are limited to digital hearing equipment like cochlear implants and hearing aids, but these are of limited benefit in patients. It is therefore urgent to understand the mechanisms of damage repair in order to develop new neuroprotective strategies. At present, how to promote the regeneration of functional hair cells is a key scientific question in the field of hearing research. Multiple signaling pathways and transcriptional factors trigger the activation of hair cell progenitors and ensure the maturation of newborn hair cells, and in this article, we first review the principal mechanisms underlying hair cell reproduction. We then further discuss therapeutic strategies involving the co-regulation of multiple signaling pathways in order to induce effective functional hair cell regeneration after degeneration, and we summarize current achievements in hair cell regeneration. Lastly, we discuss potential future approaches, such as small molecule drugs and gene therapy, which might be applied for regenerating functional hair cells in the clinic.

Objective@#To understand the current status and associated factors of comorbidity of common illnesses among primary and middle school students in Shanghai, so as to provide a reference for improving the pathogenic environment and preventing the occurrence of comorbidity of common illnesses.@*Methods@#From September to November 2021, a stratified cluster sampling method was used to select 30 331 middle school students from 112 schools in 16 districts of Shanghai, each with 2 primary schools, 2 junior high schools, 2 high schools and 1 vocational high school. Elementary school students, their health status and influencing factor questionnaires were analyzed.@*Results@#The detection rate of two or more common diseases such as myopia, overweight and obesity, high blood pressure, and abnormal spinal curvature among primary and secondary school students in Shanghai was 38.91%, of which 29.64% of primary and secondary school students had two diseases at the same time, and 9.19% had three diseases, 0.09% had 4 diseases. The detection rate of comorbidity was higher in boys (44.12%) than in girls (33.40%), and higher in junior high school students (40.40%) than in high school students (38.58%) and primary school students (38.01%). The differences were statistically significant (χ2=366.44, 50.33, P<0.01). Multifactor Logistic regression analysis showed that girls sometimes supervise themselves and often remind themselves that their sitting and standing postures were negatively correlated with the common comorbidities of primary and secondary school students (OR=0.64, 0.93, 0.90); junior middle school students and watching TV/d ≥1 h, using computers for ≥1 h/d, and using mobile electronic devices for >1 h/d were positively correlated with the comorbidity of common diseases among primary and secondary school students (OR=1.07, 1.10, 1.06, 1.10) (P<0.05).@*Conclusions@#The prevalence of comorbidity of common illnesses among primary and middle school students in Shanghai is not optimistic, which might be associated with combined effects of various external environmental factors. Targeted intervention should be implemented to effectively prevent the occurrence of comorbidities among students.

RESUMEN
Our recent studies for nonnucleoside reverse transcriptase inhibitors identified a highly potent compound JK-4b against WT HIV-1 (EC50 = 1.0 nmol/L), but the poor metabolic stability in human liver microsomes (t 1/2 = 14.6 min) and insufficient selectivity (SI = 2059) with high cytotoxicity (CC50 = 2.08 μmol/L) remained major issues associated with JK-4b. The present efforts were devoted to the introduction of fluorine into the biphenyl ring of JK-4b, leading to the discovery of a novel series of fluorine-substituted NH2-biphenyl-diarylpyrimidines with noticeable inhibitory activity toward WT HIV-1 strain (EC50 = 1.8-349 nmol/L). The best compound 5t in this collection (EC50 = 1.8 nmol/L, CC50 = 117 μmol/L) was 32-fold in selectivity (SI = 66,443) compared to JK-4b and showed remarkable potency toward clinically multiple mutant strains, such as L100I, K103N, E138K, and Y181C. The metabolic stability of 5t was also significantly improved (t 1/2 = 74.52 min), approximately 5-fold higher than JK-4b in human liver microsomes (t 1/2 = 14.6 min). Also, 5t possessed good stability in both human and monkey plasma. No significant in vitro inhibition effect toward CYP enzyme and hERG was observed. The single-dose acute toxicity test did not induce mice death or obvious pathological damage. These findings pave the way for further development of 5t as a drug candidate.
RESUMEN
OBJECTIVE To comprehensively evaluate four weekly preparations of glucagon-like peptide-1 receptor agonist (GLP-1RA) marketed in China,and to provide evidence for hospitals to optimize drug catalogs and clinical rational drug use. METHODS Mini health technology assessment method was used to establish detailed evaluation rules according to A Quick Guideline for Drug Evaluation and Selection in Chinese Medical Institutions, and conduct comprehensive evaluation of four GLP- 1RA weekly preparations from aspects of pharmaceutical characteristics, effectiveness, safety, economy and other attributes. RESULTS Mini health technology assessment scores of the four GLP-1RA weekly preparations from high to low were dulaglutide 78.60 points, semaglutide 77.35 points,polyethylene glycol loxenatide 67.40 points, and exenatide microspheres 65.50 points, respectively. Dulaglutide had advantages in reducing blood sugar, arteriosclerotic cardiovascular disease, kidney benefits, and cost- effectiveness. Semaglutide had advantages in reducing blood sugar and weight loss, but its cost-effectiveness was lower than that of dulaglutide. Exenatide microspheres had advantages in the use of children, but its daily average treatment cost is the highest. Polyethylene glycol loxenatide needed further clinical evidence. CONCLUSIONS Four GLP-1RA weekly preparations all have high pharmaceutical comprehensive scores. Dulaglutide and semaglutide may have more comprehensive pharmaceutical value among them, while the use of exenatide microspheres for children is unique.

RESUMEN
Objective@#To understand changes and health equity of low vision in children and adolescents in Chongqing, and to provide reference for student myopia prevention and control.@*Methods@#Using longitudinal studies, all school students in grades 1 to grade 12 in Chongqing were examined for visual acuity during 2018 to 2021, and the prevalence as well as changes of low vision were analyzed. In 2021, stratified random sampling was used to evaluate the health equity of uncorrected visual acuity and diopter(spherical equivalent, SE).@*Results@#The prevalence of low vision for children and adolescents in Chongqing from 2018 to 2021 was 54.12%, 58.17%, 60.03% and 58.20% respectively. Low vision showed an increasing trend in the first three years and decreased by 1.83% in 2021 as compared with 2020( χ 2 trend =13 870.45, P <0.01). The difference in the detection rate of poor vision among students in different grades was statistically significant( χ 2=17 396.36, 2 093.95, 771.87, P <0.01). From 2018 to 2021, the detection rate of low vision in girls was higher than that of boys( P <0.01). The Gini coefficient was 0.054 57 for uncorrected visual acuity in urban area, higher than in rural areas (0.035 94). Meanwhile, the Gini coefficient of urban and rural SE was 0.065 82, higher than the country (0.049 30). The results showed that myopia in children and adolescents was more uneven in urban areas.@*Conclusion@#The adjustment of myopia prevention and control strategies in the late stage of the novel coronavirus pneumonia epidemic is related to the reduction of the detection rate of poor vision in children and adolescents in Chongqing. Low vision varied by grade and gender, suggesting tailored myopia prevention and control strategy. The detection rate of poor vision in cities is more uneven than in rural areas, and different myopia prevention and control measures need to be implemented according to regional characteristics.

RESUMEN
Glucose metabolic disorder is a common issue in sepsis and it leads to an increase in mortality. However, the therapeutic methods of the glucose metabolic disorders in sepsis patients need to be improved. Studying the mechanism of glucose metabolism disorder, and adjusting the existing treatment measures are especially significant in curing the sepsis. This review summarizes recent animal experiments and clinical studies about glucose change after septic complications, focusing on the treatment of three disorders including hyperglycemia, hypoglycemia, and blood glucose variability. They definitely provide new ideas for the control of blood glucose in sepsis patients.
RESUMEN
Sepsis is a critical complication of severe trauma, large area burns, infection, and major surgery etc., which can induce septic shock and multiple organ dysfunction syndrome (MODS), and its incidence and mortality are always high. Nuclear factor-E2 related factor 2 (Nrf 2) is an important transcription factor of antioxidant stress response. It plays a key role in the treatment of sepsis by regulating the expression of antioxidant enzyme and phase Ⅱ detoxification enzyme mediated by antioxidant response element (ARE). In this article we review the changes, related regulation mechanism and reversing measures of Nrf 2 in sepsis, aiming to provide a reference for the effective intervention measures of sepsis.
RESUMEN
Objective To investigate the risk factors of acute respiratory distress syndrome (ARDS) occurrence in intensive care unit (ICU) traumatic patients. Methods Clinical data of traumatic patients in ICU of the People's Hospital of Liangping in Chongqing from January 1st, 2012 to June 30th, 2018 were retrospectively analyzed. According to the outcomes, the patients were divided into ARDS group and non-ARDS group. The differences of demographic indexes (gender, age), time of admission, type of injury, atrial fibrillation, trachea cannula, multiple injury, open injury, shock, surgery, blood transfusion, central venous indwelling catheter, infection, and blood routine indexes [white blood cell count (WBC), red blood cell count (RBC), platelet count (PLT), plateletcytocrit (PCT), hematocrit (Hct)], biochemical indexes [total bilirubin (TBil), albumin (Alb), serum creatinine (SCr), blood sodium, blood calcium, blood potassium, blood glucose], arterial blood gas analysis indexes [partial pressure of carbon dioxide (PaCO2), partial pressure of oxygen (PaO2), oxygenation index (PaO2/FiO2), blood pH], coagulation indicators [activated partial thromboplastin time (APTT), prothrombin time (PT), thrombin time (TT), international normalized ratio (INR), fibrinogen (Fib)], injury severity score (ISS), new injury severity score (NISS), acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ), sequential organ failure assessment (SOFA), Glasgow coma scale (GCS) within 24 hours of admission, and the length of ICU stay between the two groups were analyzed, and the possible influencing factors were screened out. Logistic regression model was used to analyze the risk factors of ARDS in patients with severe trauma, and receiver operating characteristic curve (ROC) was drawn to evaluate its predictive value. Results A total of 303 patients with severe trauma, including 223 males and 80 females, were enrolled. The average age was (52.98±17.03) years old. ARDS occurred in 149 cases (49.17%), including 114 males and 35 females. Compared with the non-ARDS group, the ARDS group had older age, higher rates of traffic injuries, endotracheal intubation and infection, higher blood sugar, PaO2/FiO2, TT, ISS, NISS and SOFA, lower GCS and longer the length of ICU stay. Logistic regression analysis showed that hyperglycemia, PaO2/FiO2anomalies and increased SOFA score were independent risk factors for ARDS in ICU trauma patients [blood glucose > 6.10 mmol/L:odds ratios (OR) = 2.72, 95% confidence interval (95%CI) = 1.20-6.19, P = 0.017; PaO2/FiO2< 400 mmHg (1 mmHg =0.133 kPa): OR = 7.40, 95%CI = 1.59-34.37, P = 0.011; SOFA > 5: OR = 2.92, 95%CI = 1.63-5.21, P < 0.001]. ROC curve analysis showed that blood glucose, SOFA and PaO2/FiO2could predict ARDS in ICU trauma patients, with the area under ROC curve (AUC) were 0.65, 0.70 and 0.75, respectively (all P < 0.01). The predictive value of PaO2/FiO2was better, when the cut-off value was 275 mmHg, the sensitivity was 85.89% and specificity was 70.29%. Conclusion The traumatic patients on admission with hyperglycemia, abnormal PaO2/FiO2and increased SOFA score are more susceptible to ARDS occurrence.

RESUMEN
Objective To explore the risk factors of multiple organ dysfunction syndrome (MODS) in severe trauma patients, put forward a new warning scoring system of MODS, and to provide a more accurate scoring method for doctors to judge the clinical condition and prognosis of patients. Methods Clinical data of 342 patients with severe trauma admitted to intensive care unit (ICU) of the Affiliated Hospital of Zunyi Medical College and Daping Hospital of the Third Military Medical University from January 1st, 2015 to December 31st, 2016 were retrospectively analyzed. The patients were divided into MODS groups (n = 251) and non-MODS group (n = 91) according to clinical outcomes. The clinical data of patients, including gender, age, heart rate (HR) and blood pressure within 24 hours after admission to the hospital, indicators of blood routine and blood biochemistry, severity of disease, severity of trauma, whether received the emergency intubation or surgery within 24 hours or not, whether developed sepsis or acute respiratory distress syndrome (ARDS) during hospitalization, were recorded, and univariate analysis was conducted. The indicators with statistical significance found by univariate analysis were enrolled in multivariate Logistic regression analysis, and the risk factors for MODS in patients with severe trauma were screened and assigned, and the final total score was MODS warning score. Receiver operating characteristic (ROC) curve was plotted to evaluate MODS warning score for predicting the occurrence of MODS in patients with severe trauma. Results Compared with non-MODS group, HR, Na+, serum creatinine (SCr), activated partial thromboplastin time (APTT), injury severity score (ISS), new injury severity score (NISS), acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score and sequential organ failure assessment (SOFA) score in MODS group were significantly increased, pH value, red blood cell (RBC), platelet (PLT), albumin (Alb) and Glasgow coma score (GCS) were remarkably decreased, and multiple injury, the patients with shock at admission, blood transfusion, central venous catheter, emergency intubation and infection were also increased, and more patients suffered from sepsis and ARDS. Multivariate Logistic regression analysis showed that the number of injured places equal or more than 2, shock at admission, APACHEⅡ score ≥ 15, SOFA score ≥ 4 and APTT > 40 s were risk factors for MODS in patients with severe trauma, with total MODS warning score of 7.5. ROC curve analysis showed that the area under ROC curve (AUC) of MODS warning score for predicting MODS in patients with severe trauma was 0.822, which was significantly higher than that of APACHEⅡ score (AUC = 0.698, P < 0.001), APTT (AUC = 0.693, P < 0.001) and SOFA score (AUC = 0.770, P = 0.025). When the cut-off value of MODS warning score was 2.5, the sensitivity was 61.35%, the specificity was 90.11%, and Youden index was 0.515. Conclusions MODS warning score is composed of five factors, including the number of injured places, shock at admission, APACHEⅡ score, SOFA score and APTT, which could be regarded as early warning score system for predicting MODS in patients with severe trauma. MODS warning score can be more comprehensive and timely to assess the possibility of MODS and prognosis of patients with severe trauma, and the prediction result is better than the single use of APTT, APACHEⅡ or SOFA score.

Method Forty-six patients with malignant tumor were randomized into a grain-sized moxibustion group and a control group. The grain-sized moxibustion group received grain-sized moxibustion plus regular treatment, while the control group received the regular treatment only. The cancer-related fatigue intensity [Karnofsky Performance Status (KPS), European Organization for Research on Treatment of Cancer Core Quality-of-life Questionnaire (EORTC QLQ-C30), Piper Fatigue Scale (PFS)], white blood cell count, hemoglobin level, lymphocyte count, and neutrophil count were compared before and after treatment between the two groups. The correlation between cancer-related fatigue and the observed indexes was also analyzed. Result The grain-sized moxibustion group was better than the control group in mitigating the cancer-related fatigue, up-regulating hemoglobin level, and improving the symptoms (P<0.05). Conclusion Grain-sized moxibustion can effectively mitigate cancer-related fatigue via improving anemia condition and the symptoms of malignant tumor patients, and it can also enhance the quality of life of the patients.
RESUMEN
The prevalence of childhood primary hypertension is increasing each year,not only bring-ing symptoms to these children,but also causing damage to multiple target organs such as heart,kidney,blood vessels,eyes and nerve system. Childhood hypertension is a risk factor of adult hypertension. Paying atten-tion to and preventing childhood hypertension has become a public health challenge. There are many associat-ed risk factors for childhood primary hypertension,including parental hypertension,overweight and obesity, low birth weight,and so forth. From the analysis of these factors,suggestions can be given about how to pre-vent childhood primary hypertension.
