ABSTRACT
ABSTRACT Introduction: The long-term energy imbalance between intake and consumption is the main reason for obesity in college students. Therefore, weight loss should also combine an inversely proportional intervention. Based on this premise, a growing number of studies combine physical training and diet to restore physical health in this population group. Objective: Study the impacts of endurance training associated with a low-calorie diet on the constitution and metabolism of obese college students. Methods: Through a questionnaire survey and a 4-week experimental endurance training program and hypocaloric diet, 20 obese college students volunteered for the intervention project. The exercise protocol for the training composition and the diet menu followed the updated recommendations in the scientific literature. At the end of the experiment, the relevant data collected were statistically analyzed and discussed. Results: After the diet intervention associated with endurance training, the BMI index of college students reduced from 28,075 to 26,378; the basal metabolic rate increased from 1581,046 kcal to 1681,317 kcal. Conclusion: Endurance training associated with a hypocaloric diet significantly reduced fat in obese college students. The efficacy of this association promoted a better joint effect on the outcome, compared to individual weight loss plans. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.
RESUMO Introdução: O desequilíbrio energético entre ingestão e consumo a longo prazo é o principal motivo da obesidade nos universitários, portanto, a perda de peso também deve combinar uma intervenção inversamente proporcional. Valendo-se dessa premissa, são crescentes os estudos que combinam treinos físicos e dietas com o propósito de restaurar a saúde física nessa parcela da população. Objetivo: Estudar os impactos do treino aeróbico associado a dieta hipocalórica sobre a constituição e o metabolismo de estudantes universitários obesos. Métodos: Através de uma pesquisa por questionário e um programa experimental com duração total de 4 semanas de treino aeróbico e dieta hipocalórica, 20 universitários obesos voluntariaram-se para o projeto de intervenção. O protocolo de exercícios para a composição do treino e o cardápio da dieta seguiram as recomendações atualizadas da literatura científica. Ao final do experimento, os dados relevantes coletados foram analisados estatisticamente e discutidos. Resultados: Após a intervenção da dieta associada ao treino aeróbico, o índice IMC de estudantes universitários reduziu de 28.075 para 26.378; o índice metabólico basal aumentou de 1581.046 kcal para 1681.317 kcal. Conclusão: O treino aeróbico associado à dieta hipocalórica demonstrou um efeito significativo na diminuição da gordura dos universitários obesos. A eficácia dessa associação promoveu um melhor efeito conjunto no resultado, em comparação a planos individuais de emagrecimento. Nível de evidência II; Estudos terapêuticos - investigação dos resultados do tratamento.

ABSTRACT
Objective@#To investigate the effect of elective neck dissection on the 5-year survival rate of patients with early oral squamous cell carcinoma.@*Methods@#The data of 100 patients with early oral squamous cell carcinoma (cT1-2N0M0) were retrospectively analyzed. In 61 cases, the primary tumor was subjected to elective neck dissection (END). Neck observation and follow-up (NOF) were performed in 39 cases with enlarged resection of primary lesions. Clinicopathological data such as pT staging, pathology classification,the rate of cervical lymph node metastasis and the 5-year survival rate of the patients were statistically analyzed.@*Results@#The 5-year survival rates of the END and NOF groups were 86.9% and 69.2%, respectively, and the difference was statistically significant (P=0.028). END treatment was significantly better than NOF in controlling cervical lymph node metastasis in early oral squamous cell carcinoma (P=0.009). After stratified analysis of histopathological features, the 5-year survival rate of patients with pathological T2 (pT2) stage OSCC in the END group was significantly higher than that in the NOF group (P=0.020). The 5-year survival rate of patients with moderate and poorly differentiated pathological grade OSCC in the END group was significantly higher than that in the NOF group (P=0.013). @*Conclusion @# END is effective for the management of the cervical lymph node metastasis rate in early OSCC patients. For patients with pT2 stage or low differentiation pathological grade, active END can significantly improve the 5-year survival rate.
ABSTRACT
Severe traumatic brain injury (sTBI) as the most common emergency severe syndrome in neurosurgery has a high mortality and poor prognosis. Decompressive craniectomy is the first treatment choice for sTBI. The reverse question mark incision was usually adopted in decompressive craniectomy, but some scholars also suggest using the n-type incision and Kempe incision. Although the curative effect is remarkable when using the above incisions, the incidence of postoperative complications is high, such as cerebrospinal fluid leakage, poor wound healing and flap ischemic necrosis. Moreover, the advantages and disadvantages of different incisions are not clear. Therefore, some scholars proposed retroauricular incision decompressive craniectomy for sTBI patients because this incision that retains blood supply through a new flap can provide better decompression effect and reduce incision-related complications. The authors review the research progress in retroauricular incision in aspects of the methods, indications and its advantages and disadvantages in constrast with other incisions, so as to provide a theoretical basis for the selection of incision for decompressive craniectomy in sTBI patients.
ABSTRACT
OBJECTIVE@#To evaluate retrospectively the effect of general anesthesia on DNA damage in the blood mononuclear cells (PBMCs) of surgical patients in order to provide evidence for a better nursing care during the procedure.@*METHODS@#Clinical charts of 76 patients who underwent operation under general anesthesia and 76 healthy control subjects with documented results of DNA damage extent in PBMCs from the single-cell gel electrophoresis (SCGE) or comet assay and serum contents of superoxide dismutase (SOD) and malondialdehyde (MDA) from biochemical analyses were reviewed. The percentage of comet PBMCs and tail DNA and serum contents of SOD and MAD were analyzed by student t-test.@*RESULTS@#Compared with healthy control subjects, generally anesthetized surgical patients had significantly higher % comet PBMCs and % tail DNA (P <0.05) and significantly lower serum concentrations of SOD (P<0.05) and significantly higher serum concentrations of MAD (P<0.05). Compared with levels before general anesthesia in surgical patients, % comet PBMCs, % tail DNA, and serum levels of MAD were significantly higher (P<0.05 or 0.01, and serum levels of SOD were significantly lower (P<0.05, after general anesthesia.@*CONCLUSIONS@#General anesthesia during surgery causes a certain degree of hypoxia and PBMC damage. Particular attention should be paid to monitoring and maintenance of blood oxygen saturation in patients undergoing surgery under general anesthesia.

ObjectiveTo observe the different mode of administration of lidocaine on hemodynamic effects during self-retaining laryngoscope.Methods75 adult patients,underwent selective operations of removal and biopsy of the vocal polype,epiglottis or laryngeal tumor via self-retaining laryngoscope under general anesthesia,were randomly divided into three groups,with 25 cases for each.Group Ⅰ was the control group; Group Ⅱ was the throat spraying group;Group Ⅲ was the intravenous drug group.The incidence of irritating cough and the changes of mean arterial pressure(MAP) and hear rate(HR) were observed during operations.ResultsThe incidence of irritating cough in group Ⅱ was lower than in group Ⅰ and group Ⅲ ( all P ＜ 0.05 ).MAP,HR in group Ⅱ was also lower than that in group Ⅰ and Ⅲ during extubation( all P ＜0.05).However there were no significant differences on MAP,HR between group Ⅰ and group Ⅲ during extubation( all P ＞ 0.05 ).ConclusionLidocaine spraying on larynx could alleviate irritating cough and had significant preventive effect on cardiovascular response,and the effect in this method was superior to intravenous injection.
ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the effects of acupuncture on post-stroke spastic paralysis.</p><p><b>METHODS</b>A systematic evaluation including all the relavant randomized controlled trials (RCTs) or quasi-RCTs of acupuncture and moxibustion for treatment of post-stroke spastic paralysis were carried out according to the method recommended by the Cochrane Collaboration.</p><p><b>RESULTS</b>Nine hundred and seventy-eight patients being included in fourteen papers met the enrolled criteria. However, their methodological quality was relatively poor. Meta-analysis of nine trials indicated that there was no significant difference between the treatment groups and the control groups in Ashworth scores, Carr-Shepherd scores, nerve defect scores and hip adductor tension scores. Whereas the Fugel-Meyer scores in one trial and the Barthel scores in three trials were better in the treatment groups than those of the control group.</p><p><b>CONCLUSION</b>A reliable conclusion can not be drawn from the present data because of the defects in methodological quality and insufficient numbers of trials, especially lack the long-term terminal outcomes, although it appears a tedency that acupuncture can improve the conditions of post-stroke spastic paralysis. Therefore, it is necessary to perform more multi-central RCTs of high quality in future.</p>

OBJECTIVE@#Based on the sequence differences of Amelogenin homologous gene in the X and Y chromosomes, a pair of specific primers was designed to identify the sex of archaeological samples.@*METHODS@#Ancient DNA fragments were extracted from the bones and teeth of sacrificial slaves with an improved method that combines phenol-chloroform extraction, silicon dioxide adsorption with ultrafiltration concentration. The polyacrylamide gel electrophoresis (PAGE) was used to detect PCR products.@*RESULTS@#Seven in sixteen samples from eight graves showed positive results and the targeted segments were visible: a male with two bands of 106bp (Amel-X) and 112 bp (Amel-Y), while a female with only one band of 106 bp (Amel-X). Ancient DNA analyzing results from tooth samples are more marked than that from bones.@*CONCLUSION@#The improved extraction method is more effective for ancient DNA extraction, which reduced the PCR inhibitors and lowered experimental costs. The sex determination technology based on Amelogenin homologous gene is an important and feasible method in the molecular archaeological research.
