Objective: To explore the intervention effects of high intensity interval training (HIIT) on glucose metabolism, cortisol (Cor), and sleep quality among college students with comorbid depressive symptoms and obesity, so as to provide a reference for improving sleep quality among college students with comorbid depressive symptoms and obesity. Methods: In March 2023, 45 college students with comorbid depressive symptoms and obesity were recruited and randomly assigned to an exercise group ( n =23) and a control group ( n =22) by random number table method. The exercise group received HIIT intervention for 12 weeks, three times a week, while the control group received no intervention. Blood samples were collected from participants to measure fasting insulin (FINS), fasting blood glucose (FBG), homeostatic model assessment of insulin resistance (HOMA-IR), Cor, and Pittsburgh Sleep Quality Index (PSQI) before and after intervention. Statistical analysis was performed using t-test, repeated measures analysis of variance (ANOVA), simple effect analysis. Results: The repeated measures ANOVA revealed statistically significant time×group interaction effects for body composition (weight, body mass index, percentage of body fat, fat mass, waist to hip ratio), depressive symptoms, PSQI scores and its subdimensions (subjective sleep quality, sleep onset time, sleep efficiency, sleep disorders, daytime dysfunction), as well as FBG, FINS, and HOMA-IR between the exercise group and control group before and after intervention ( F =7.10-53.38, all P <0.05). Simple effect analysis showed that compared to the control group, the exercise group demonstrated significant improvements in body composition (body mass index, fat mass, waist to hip ratio), depressive symptoms, PSQI scores and its sub dimensions (subjective sleep quality, sleep onset time, sleep efficiency, sleep disorders, daytime dysfunction), FBG, FINS, HOMA-IR, and Cor (all P <0.05). Conclusion HIIT can improve the sleep quality of college students with comorbid depressive symptoms and obesity by enhancing glucose metabolism and regulating Cor levels.

Objective:To evaluate the efficacy and safety of Xiao′er Huangjin Zhike Granules in the treatment of cough caused by acute bronchitis in children, which is defined in TCM terms as a syndrome of phlegm-heat obstructing the lung.Methods:This was a block-randomized, double-blind, placebo-controlled, multicenter clinical trial.From January 2022 to September 2023, 359 children aged 3 to 7 years old diagnosed as acute bronchitis (lung-obstructing phlegm-heat syndrome) were enrolled from 21 participating hospitals and randomly assigned to the experimental group and placebo group in a 3︰1 ratio, and respectively treated with Xiao′er Huangjin Zhike Granules and its matching placebo.Cough resolution/general resolution rate after 7 days of treatment was used as the primary efficacy outcome for both groups.Results:(1)On the seventh day of treatment, the rate of cough disappearance/basically disappearance in the experimental group and placebo group were 73.95% and 57.61% retrospectively, which had statistically significance ( P=0.001).(2)After 7 days of treatment, the median duration of cough disappearance/basic disappearance were 5 days and 6 days in the two groups , with a statistically significant difference ( P=0.006).The area under the curve of cough symptom severity time was 7.20 ± 3.79 in the experimental group and 8.20±4.42 in the placebo group.The difference between the two groups was statistically significant ( P=0.039).(3) After 7 days of treatment, the difference between TCM syndrome score and baseline was -16.0 (-20.0, -15.0) points in the experimental group and -15.0 (-18.0, -12.0) points in the placebo group, with significant difference between the two groups ( P=0.004).In the experimental group, the clinical control rate, the markedly effective rate, the effective rate and the ineffective rate were 49.04%, 28.35%, 16.48% and 6.13% severally; and in the placebo group, the clinical control rate, the markedly effective rate, the effective rate and the ineffective rate were 38.04%, 26.09%, 29.35%, and 6.52% separately, which had statistically significant ( P=0.014).(4) There was no significant difference in the incidence of adverse events or adverse reactions during the trial between both groups.Moreover, while adverse reactions in the form of vomiting and diarrhea were occasionally reported, no serious drug-related adverse event or adverse reaction was reported.(5)The tested drug provided good treatment compliance, showing no statistically significant difference from the placebo in terms of compliance rate. Conclusions:Based on the above findings, it can be concluded that Xiao′er Huangjin Zhike Granules provides good safety, efficacy, and treatment compliance in the treatment of cough caused by acute bronchitis, and lung-obstructing phlegm-heat syndrome, in children.

Objective : To analyze the difference of urinary iodine level in Hashimoto thyroiditis ( HT) patients， and to explore the possible relationship between urinary iodine level and HT under different iodine nutritional sta- tus，so as to provide some references for reasonable iodine intake in HT patients． Methods : A total of 101 hospi- talized HT patients were selected as HT group and divided into 3 groups according to thyroid function : HT group with hyperthyroidism (41 cases) ．There were 25 cases in HT group with normal thyroid function．There were 35 cases in HT combined with hypothyroidism group．In addition，30 healthy subjects were selected as control group. Serum levels of thyroid stimulating hormone(TSH) ，triiodothyronine(T3 ) ，thyroxine (T4 ) ，thyroid peroxidase an- tibody (TPOAb) and thyroglobulin antibody (ATG) were detected by chemiluminescence assay．The size and mor- phological structure of thyroid organs were examined by ultrasonography．Urinary iodine was determined by catalytic spectrophotometry with arsenic and cerium．The nutritional status of iodine was classified into iodine deficiency ( < 100 μg/ L) ，iodine adequacy( 100 －199 μg/ L) ，iodine adequacy (200 －299 μg/ L) and iodine excess ( ≥ 300 μg/ L) ．Non-parametric test was used to compare urinary iodine level between HT group and control group，one- way ANOVA and t test were used to compare urinary iodine level between HT group and control group ，and Spearman correlation analysis was used to compare the correlation between urinary iodine level and T3 ，T4 ，TSH， ATG and TPOAb under different iodine nutrition status. Results : Compared with control group，ATG and TPOAb levels in HT group increased (P＜0. 001) ，and urinary iodine levels increased (P＜0. 05) ，with statistical signifi- cance．Compared with the control group in different thyroid function states，only the HT group with hypothyroidism increased the urinary iodine level (P＜0. 01) ，and the difference was statistically significant．Spearman correlation analysis showed that urine iodine level was positively correlated with ATG and TPOAb levels in iodine excess condi- tion (P＜0. 05) ，and urine iodine level was positively correlated with TSH level in iodine sufficient condition and iodine excess condition in HT patients (P＜0. 05) ． Conclusion The urinary iodine level of HT patients was high- er than that of normal people．When the urinary iodine level of residents is ≥ 300 μg/ L，iodine intake is prone to HT．When the urinary iodine level of HT patients is ≥ 200 μg/ L，iodine consumption is prone to hypothyroidism， and iodine intake should be limited.

AIM: To investigate the effects of serum 25-hydroxyvitamin D (25(OH)D) on the blood glucose and islet β-cells function in the elderly with type 2 diabetes (T2DM). METHODS: Fifty-eight elderly patients with type 2 diabetes were recruited from June 2019 to January 2020, and all the patients were divided into three groups according to levels of serum 25(OH)D. Age, body mass index (BMI) and the levels of fasting blood glucose (FBG), hemoglobin A1c (HbA1c) were analyzed. Steamed bread meal test was performed in all patients, and the levels of blood glucose and C-peptide were compared among the three groups at the time points of 0, 30, 60, 120 and 180 min to investigate the effect of serum 25(OH)D on the islet β-cells function.RESULTS: Compared with the elderly T2DM patients with sufficient 25(OH)D, the HbA1c increased significantly in the elderly T2DM patients with deficiency of 25(OH)D (P<0.05). The levels of blood glucose were increased at the time points of 120 min and 180 min, while the levels of C-peptide at the time point of 60 min and 120 min, C peptide index and AUCCP180 in elder T2DM patients decreased significantly (P<0.05). Pearson correlation analysis showed that serum was negatively correlated with HbA1c, and positively correlated with the C peptide and C peptide index and AUCCP180 (P<0.05). And stepwise multiple regression analysis indicated that C peptide was a factor influencing 25(OH)D levels. CONCLUSION: Elderly T2DM patients with deficiency of 25(OH)D are more likely to suffer with severe dysfunction of islet β-cells.

BACKGROUND: Percutaneous vertebroplasty is an effective method for osteoporotic thoracic vertebral compression fracture, but bone cement leakage is easy to occur in patients with intravertebral cleft. OBJECTIVE: To explore the therapeutic efficacy of bone-filling mesh containers in elderly patients with osteoporotic vertebral compression fractures combined with intravertebral cleft sign. METHODS: From October 2017 to July 2018, 62 patients aged from 60 to 80 years with osteoporotic vertebral compression fractures combined with intravertebral cleft sign were admitted at the Affiliated Hospital of Qinghai University. Among them, 31 cases were treated with unilateral percutaneous vertebroplasty (control group), and the other 31 cases were treated with bone-filling mesh containers (study group). The leakage of bone cement, the time of operation and the times of fluoroscopy were recorded in the two groups. The visual analogue scale score and Oswestry disability index score were compared between the two groups before and 7, 30, 60 days after treatment. The height changes of injured vertebrae were evaluated by X-ray before treatment and 7 days after treatment. The quality of life was evaluated by the MOS item short from health survey (SF-36) before and 60 days after treatment. RESULTS AND CONCLUSION: (1) The time of operation and the times of fluoroscopy in the study group were less than those in the control group (P < 0.05), and the leakage rate of bone cement in the study group was lower than that in the control group (6％ vs. 39％, P < 0.05). (2) The visual analogue scale score and Oswestry disability index score of the two groups were significantly improved at 7, 30 and 60 days after treatment. The visual analogue scale scores of the study group were lower than those of the control group at different time points after treatment (P < 0.05). There was no difference in Oswestry disability index scores between the two groups at different time points after treatment (P> 0.05). (3) The height of injured vertebrae 7 days after treatment in both groups was significantly higher than that before treatment (P < 0.05), and there was a significant difference between the two groups (P < 0.05). (4) The quality of life of the two groups was significantly improved at 60 days after treatment (P < 0.05), but there was no difference between the two groups (P> 0.05). These findings indicate that compared with unilateral vertebroplasty with bone cement injection, bone-filling mesh containers with bone cement injection could reduce the incidence of cement leakage, relieve pain and increase the height of injured vertebrae in elderly patients with osteoporotic vertebral compression fracture combined with intravertebral cleft sign.

Objective To investigate the effect of different noise index (NI) combined with iterative recombination on the image quality and radiation dose of CT scan in patients with different body mass index (BMI). Method One hundred and sixty patients who had a liver CT enhanced scan were divided into group A (18 kg/m2≤BMI<24 kg/m2 ) and group B (24 kg/m2≤BMI<31 kg/m2) according to BMI, and each group had 80 patients. The two groups were randomly divided into 4 subgroups which NI value was 11, 13, 15 and 17 respectively. All images were restructured with 50% adaptive statistical iterative reconstruction. Subjective evaluation, objective evaluation [signal noise ratio (SNR) and contrast noise ratio (CNR)] and the effective dose of each group were recorded and calculated after the scan. ANOVA and Kruskal-Wallis test were used to evaluated the difference of imaging quality and radiation dose. Results In group A, the SNR, CNR and the subjective score of the later arterial phase images showed a statistical difference between NI=17 group and other subgroups (P<0.05), while there was no statistical differences among the other three subgroups during three CT enhanced phase. The average ED of NI=15, 17 group were decreased by 57.56%(2.17/3.77) and 61.54% (2.32/3.77) compared with NI=11 group, respectively. In group B, the SNR, CNR and the subjective image scores of the later arterial phase showed a significant difference between NI=15 and NI=11, 13 group (P<0.05). There was a statistically difference of image quality in group NI=17 compared with the other three subgroups in the later arterial phase, portal venous phase and equilibrium phase (P<0.05). The average ED of NI= 13, 15 group was decreased by 26.41% (1.69/6.40) and 45.31%(2.90/6.40) compared with NI=11 group, respectively. Conclusion Upon maintaining diagnostic imaging quality, setting different NI according to BMI and applying the iterative reconstruction algorithm can effectively reduce the radiation dose of liver CT enhanced scanning.

This study was aimed to explore the characteristics of urine metabolomics among HIV/AIDS patients with spleen-lung qi-deficiency. H-NMR technique was combined with principal component analysis and cluster analysis in the comparison of urine metabolic products among 24 HIV/AIDS cases with spleen-lung qi-deficiency and 20 healthy control cases. The results showed that urine metabolic products of HIV/AIDS patients with spleen-lung qi-deficiency and healthy people by H-NMR technique detection and PLS-DA analysis can classify the outline of urine metabolites. There were about 20 variables in the difference between two groups. The speculated substances contained glycyl-L-leucine, L-valine, α-aminobutyric acid, methyl succinic acid, glycine propionyl, and etc. It was concluded that H-NMR technique was able to classify the outline of urine metabolites between HIV/AIDS cases with spleen-lung qi-deficiency and healthy people. Part of the potential existed characteristic markers contributed to the clinical diagnosis of traditional Chinese medicine (TCM) syndrome differentiation of AIDS. It had certain effect in its quantitative analysis.

Objective To analyze the clinical characteristics,prognosis and molecular biological changes of tonsillar squamous cell carcinoma(TSCC).Methods Retrospective analysis of 61 TSCC cases treated from January 1999 to December 2012.Demographic data and clinical charts,including histologic grade of tumor,treatment and outcome of the patients,were reviewed.Human papillomavirus (HPV)-DNA were detected using SPF10-DNA enzyme immunoassay and LiPA genotyping method.Expressions of p16 and p53 proteins were examinated by immunohistochemistry.Survival rate was calculated with SPSS 19.0 software using the Kaplan-Meier method.Results There were 55 males and 6 females,with a median age of 57 years.Of the 61 TSCC,21 were with well differentiation,19 with moderate differentiation and 21 with poor differentiation,including 7 patients at stage Ⅱ,10 at stage Ⅲ and 44 at stage Ⅳ.HPV-positive rate of TSCC was 29.5％ (18/61) and high-risk HPV-16 subtype accounted for 72.2％ (13/18).The percentage of famel patients in HPV-positive TSCC was higher than HPV-negative TSCC(22.2％ vs 4.7％).HPV-positive TSCC was more common in non-smoking patients (50.0％ vs 79.1％,x2 =5,155,P =0.023) and non-drinking patients (27.8％ vs 51.2％,x2 =4.346,P =0.037).HPV-positive TSCC mostly presented with high expression of p16 protein (88.9％ vs 16.3％,x2 =28.481,P =0.000),and low expression of p53 protein(72.7％ vs 46.5％,x2 =5.028,P =0.025).The prognosis of patients with HPV-associated TSCC was significantly better than non-HPV-associated TSCC,and The 3-year and 5-year overall survival rates of patients with HPV-positive TSCC were higher than those of patients with HPV-negative TSCC (87.7％ vs 49.5％ and 78.9％ vs 33.0％,respectively).Conclusion HPV-associated TSCC had unique clinicopathological and molecular biological features,showing better prognosis compared to HPV-negative TSCC.
