ABSTRACT

Objective:To analyze the clinical characteristics of obese adolescents undergoing metabolic and bariatric surgery for the purpose to guide clinical decision-making and practice of metabolic and bariatric surgery in adolescents.Methods:The perioperative clinical profile of 123 adolescent patients under the age of 21 years who underwent metabolic and bariatric surgery in Beijing Friendship Hospital, Capital Medical University from 2018 to 2021 were extracted, and compared their clinical data with the overall data of 6807 patients in the 2021 GC-MBD Annual Report. Analyzed the clinical characteristics of adolescent weight loss metabolic surgery patients from multiple aspects such as preoperative complications, surgical methods, surgical outcomes, and follow-up. Statistical analysis was conducted using SPSS25.0 software.Results:Among adolescent bariatric surgery patients, the proportion of female patients (74.0%) was higher than that of male patients (26.0%). Except for the incidence of polycystic ovary syndrome (31.9%), which was higher than the overall rate, the proportion of other related diseases or symptoms was low and usually mild. The changes of systolic blood pressure ( Z=-5.73, P<0.001), body weight ( Z=-5.69, P<0.001), umbilical abdominal circumference ( Z=-2.40, P=0.017), glycosylated hemoglobin ( Z=-5.23, P<0.001), fasting insulin ( Z=-2.95, P<0.003), fasting C-peptide ( Z=-4.59, P<0.001), triglyceride ( Z=-2.75, P=0.006) at 3 months after operation were statistically significant compared with those before operation. The changes of systolic blood pressure ( Z=-3.42, P=0.001), body weight ( Z=-5.14, P<0.001), umbilical abdominal circumference ( Z=-2.86, P=0.004) and glycosylated hemoglobin ( Z=-2.67, P<0.008), fasting C-peptide ( Z=-2.09, P=0.037), high-density lipoprotein ( Z=-2.08, P=0.038) at 6 months after operation were statistically significant compared with those before operation. Conclusions:The outcomes of bariatric surgery in obese adolescents are similar to those in adults. The indications and timing of bariatric surgery need to be further explored. In view of the high proportion of females, poor self-management ability and low follow-up compliance of adolescent patients, it is urgent to construct a full-cycle care model suitable for adolescent patients with bariatric surgery to improve their self-management ability, follow-up compliance and long-term clinical outcomes.

ABSTRACT

Objective:To investigate the therapeutic clinical effect of laparoscopic high uterosacral ligament suspension (LHUS) combined with cervical amputation and vaginal sacrospinal ligament fixation (SSLF) in the treatment of prolapse of uterus in childbearing period.Methods:From October 2011 to December 2016, the clinical data of 78 patients with uterine prolapse above grade Ⅱ treated in Department of Gynecology, Jizhong Energy Fengfeng Group Hospital were retrospectively analyzed.According to different surgical methods, the patients were divided into LHUS group (40 cases) and SSLF group (38 cases). The operation time, intraoperative bleeding volume and hospital stay of the two groups were compared by independent sample t test.Before and 6 months after the operation, the prolapse quality of life questionnaire (P-QOL), pelvic organ prolapse/incontinence sexual function questionnaire-12 (PISQ-12) and pelvic floor distress inventory-short form 20 (PISQ-20) were used.PFDI-20 and pelvic floor impact questionnaire-short 7 (PFIQ-7) were used to evaluate patients′ quality of life, sexual function and pelvic floor function.Paired t test was used to compare the above scores before and 6 months after operation in the same group.Results:There were no significant differences in operation time, intraoperative bleeding volume and hospital stay between the two groups ( t value were 1.593, 1.203 and 0.535, , respectively, all P>0.05). The preoperative P-QOL, PISQ-12, PFDI-20, and PFIQ-7 scores of patients in the LHUS group were (55.4±11.1), (25.1±4.6), (15.0±4.9), (8.9±2.8) points, and (53.7±10.5), (23.9±3.7), (14.1±4.2), (9.2±3.0) in the SSLF group.There was no statistically significant difference in the indexes between the two groups before operation (t value were 0.694, 1.265, 0.869 and 0.457, respectively, all P>0.05). The scores of P-QOL, PISQ-12 at 6 months after operation in LHUS group((87.9±12.0), (39.1±6.1)) and SSLF group((81.3±11.7), (35.6±4.0)) were significantly higher than those before operation( t value were 12.574, 11.589, 10.823 and 13.236, respectively, all P<0.001). The scores of P-QOL and PISQ-12 at 6 months after operation in the two groups were higher than those before operation((87.9±12.0), (39.1±6.1)), and the P-QOL score of LHUS group was higher than that of SSLF group 6 months after operation, the difference was statistically significant ( t value were 12.574, 11.589, 10.823 and 13.236, respectively, all P<0.001). At 6 months after operation, PFDI-20 and PFIQ-7 scores in LHUS group((2.1±0.3), (1.3±0.2) points) were significantly lower than before operation ( t value were=16.619 and, 17.123, all P<0.001). The PFDI-20 and PFIQ-7 scores in LIHUS group were lower than those in SSLF group((2.7±0.3), (1.9±0.2)) at 6 months after operation (t values were 10.096 and 13.073, respectively, all P<0.001). Conclusion:LHUS combined with cervical resection in the treatment of prolapsed uterine prolapse can effectively improve the quality of life, sexual function, and pelvic floor function.The effect is better than SSLF, which is worthy of clinical promotion.

ABSTRACT

Objective:To investigate the prognostic value of serum levels of miR-134 and miR-146b in elderly patients with acute ischemic stroke(AIS).Methods:A total of 162 elderly patients with AIS admitted to the Third People's Hospital of Haikou from January 2017 to October 2019 were enrolled.According to modified Rankin Scale(mRS)scores, they were divided into the good prognosis group(n=98, mRS score≤2)and the poor prognosis group(n=64, mRS score>2). Based on the National Institutes of Health Stroke Scale(NIHSS), patients were divide into the mild group(n=46, NIHSS score<5), moderate group(n=75, 5≤NIHSS score≤20), and severe group(n=41, NIHSS score>20). Real-time fluorescence quantitative PCR was used to detect serum levels of miR-134 and miR-146b in each group.Multivariate logistic regression was used to analyze risk factors for poor prognosis in elderly patients with AIS.The receiver operating characteristic(ROC)curve was used to analyze the value of serum miR-134 and miR-146b levels in predicting poor prognosis of elderly patients with AIS.Pearson correlation was used to analyze the correlations of serum levels of miR-134 and miR-146b with NIHSS and mRS scores in elderly patients with AIS.Results:Serum levels of miR-134(3.26±1.13 vs.0.85±0.38)and miR-146b(2.27±0.93 vs.0.56±0.21)were higher in the AIS group than in the control group( t=14.360 and 12.527, P<0.01). Serum levels of miR-134(4.35±1.46 vs.2.28±0.85)and miR-146b(3.07±1.04 vs.1.51±0.66)were higher in the poor prognosis group than in the good prognosis group( t=13.520 and 11.242, P<0.01). Serum levels of miR-134 and miR-146b in the severe group were higher than in the moderate and mild groups( t=10.815 and 9.462, P<0.01), and they were also higher in the moderate group than in the mild group( t=13.627, 11.611, P<0.01). Multivariate Logistic regression analysis showed that serum miR-134( OR=2.470, 95% CI: 1.603-4.927)and miR-146b( OR=1.914, 95% CI: 1.350-3.406)were risk factors for poor prognosis in elderly AIS patients( P<0.05). The ROC curve analysis showed that the optimal cut-off values of serum miR-134 and miR-146b to predict poor prognosis in elderly AIS patients were 3.84 and 2.68, respectively.The area under the ROC curve(AUC)of combined serum miR-134 and miR-146b(0.926, 95% CI: 0.865-0.987)for the prediction of poor prognosis was higher than that of either marker alone, with a sensitivity and specificity of 92.4% and 86.2%, respectively.The correlation analysis showed that serum levels of miR-134 and miR-146b were positively correlated with NIHSS and mRS scores in elderly AIS patients( r=0.806, 0.871, 0.785 and 0.842, all P<0.01). Conclusions:Increased serum miR-134 and miR-146b levels are correlated with the severity of neurological impairment and prognosis in elderly patients with AIS.Serum miR-134 and miR-146b levels together have a high value in predicting poor prognosis in elderly AIS patients.

ABSTRACT

Objective To observe the effects of Lianggesan on serum citrulline and intestinal fatty acid binding protein (IFABP) levels in patients with mechanical ventilation and acute gastrointestinal injury (AGI). Methods Eighty patients with mechanical ventilation and AGI admitted to Tianjin First Center Hospital from May to December 2017 were divided into a conventional treatment group and a traditional Chinese medicine (TCM) treatment group according to different treatment methods, 40 cases in each group; 10 patients with mechanical ventilation but without AGI were selected as a control group. All patients were given invasive mechanical ventilation after admission, and the gastrointestinal tract intervention was carried out according to AGI grading treatment process; Lianggesan (compositions:forsythia suspensa 30 g, scutellaria 10 g, gardenia 10 g, bamboo leaf 10 g, rhubarb 10 g, mint 6 g, mirabilite 6 g, licorice 15 g) was added to the TCM treatment group on the basis of the conventional treatment. The above TCM drug used was a single Chinese medicine granule produced by Jiangyin Tianjiang Pharmaceutical Co., Ltd. Each single Chinese herbal granule was proportionally poured into 200 mL boiling water at 80-100 ℃, 100 mL each time, twice daily nasal feeding for one week. The changes of serum citrulline and IFABP levels were observed before and 1, 3, 5 and 7 days after treatment in the three groups. Results Before treatment, serum citrulline levels in the conventional treatment group and the TCM treatment group were significantly lower than those in the control group (μmol/L: 19.84±4.74, 20.84±4.65 vs. 28.89±2.18, both P < 0.05), and IFABP levels were significantly higher than those in the control group (ng/L:571.89±42.89, 552.49±44.78 vs. 155.68±22.95, both P < 0.05), there were no significant differences between the conventional treatment group and the TCM treatment group (P > 0.05); with the extension of treatment time, the levels of citrulline in the conventional and TCM treatment groups were decreased first and then increased gradually, reaching the valley value on the first day of treatment [the two groups were (16.12±4.44), (18.49±4.59) μmol/L] respectively, and then increased gradually, reaching the peak value on the 7th day of treatment, the increased range of citrulline in the TCM treatment group was more obvious than that in the conventional treatment group (μmol/L: 26.77±4.18 vs. 22.75±3.07, P < 0.05), and the treatment lasted for 5 days, and 7 days, the level of citrulline in the TCM treatment group was close to that in the control group; the IFABP levels in the conventional treatment group and the TCM treatment group were increased first and then decreased gradually, reaching the peak value on the first day of treatment [the two groups were (654.23±63.24), (630.32±49.11) ng/L] respectively, and then decreased gradually, reaching the trough value on the 7th day of treatment, the degree of decrease in the TCM treatment group was more obvious than that in the conventional treatment group (ng/L: 262.21±30.89 vs. 375.43±44.43, P < 0.05), but the level of IFABP in the TCM treatment group was still significantly higher than that in the control group (ng/L: 262.21±30.89 vs. 158.95±29.34, P < 0.05). Conclusion Lianggesan can elevate the serum citrulline level, reduce the serum IFABP level, and effectively improve the intestinal function of patients with mechanical ventilation and AGI.

ABSTRACT

Objective@#To investigate the prevalence of biting pencils among pupils living in Harbin, Guangzhou, and Beijing and to compare the differences among these cases.@*Methods@#Stratified sampling method was used to select four elementary schools in Harbin and Guangzhou from April 2015 to April 2016. Firstly, Simple random sampling method was used in every grade (grade 1-grade 5) to select 3 or 4 classes (71 classes in total).After the sample selection, questionnaire surveys were conducted among pupils and their guardians (anyone of their guardians) who belonged to these classes. Secondly, the study extracted part of these pupils to conduct a field survey. Every school was classified by grade, and every grade adopted the method of random sampling to select one classes (20 classes in total). Meanwhile, the study randomly selected pupils from 10 classes in 2 elementary schools in Beijing. All together, 1 627 pupils participated in the field survey. The questionnaire included general information about the students and their guardians, the situation of biting pencils, the awareness of the harm of biting pencils, etc.; the field survey considered if participates' pencils have tooth marks and the severity of the marks, etc. χ2 was applied to test and compare the differences among pupils of different genders and different cities. The comparison focused on the proportion of students who bited pencils, the proportion of pencils with tooth marks and the proportion of students and guardians already awared of the harm of biting pencils, etc.@*Results@#The number of the valid questionnaires in Harbin and Guangzhou were 1 842, and 1 210, respectively. The occurrence rate of pupils biting pencils in Harbin (18.0% (333/1 842)) was higher than that in Guangzhou (11.3% (137/1 210)) (χ2=29.16, P=0.001). Specifically, in Harbin, the rate of boys biting pencils was 21.9% (212/965), which was higher than girls (13.8% (121/877)) (χ2=27.04, P=0.001). Similarly, in Guangzhou, the rate of boys biting pencils was 14.5% (92/632), which was also higher than girls (7.7% (45/578)) (χ2=15.34, P=0.001). The awareness rate of the harm of biting pencils among students from these two cities were 88.5% (1 611/1 819), and 90.8% (1 098/1 208), respectively, and the difference was statistically significant as well (χ2=4.39, P= 0.020). Compared with these data, the awareness rate of the harm of biting pencils among guardians from these two cities were 74.7% (1 339/1 791), and 79.4% (832/1 047), respectively as well as the statistically significant difference appeared (χ2=9.83, P=0.007). The result of field survey showed the rate of tooth-marked pencils in Harbin, Guangzhou and Beijing was 30.5% (187/613), 14.8% (79/534), and 28.3% (136/480), respectively. The difference was also statistically significant (χ2=42.68, P=0.001). The degree of tooth marks was mainly mild, while the percentage of mild degree in Guangzhou (54.4%(43/79)) and Beijing (41.2% (56/136)) was apparently higher than that of Harbin (39.0% (73/187)). The difference was not statistically significant (χ2=7.01, P=0.136).@*Conclusion@#The behavior of biting pencils existed universally among pupils in Harbin, Guangzhou, and Beijing , which the situation of pupils biting pencils in Harbin and Beijing was more serious than that in Guangzhou. Pupils, parents and teachers should pay attention to such a behavior.

ABSTRACT

To research on the effect of DC-CIK cells on human lymphoma cell line Raji the immunophenotype of DCCIK cells was analyzed using flow cytometry, and its proliferation inhibition effect was detected using MTT assay. 24 nude mice [4-6 weeks old] were employed and inoculated Raji cells on right axillaries for constructing human Burkitt lymphoma model. MTT results showed that DC-CIK cells had a significant inhibitory effect on Raji cells with obvious dose- and time- dependent effect. Western Blot results confirmed that DC-CIK cells could significantly down regulate the expression of BCL-2 [P<0.05]. DC-CIK cells possesses significant anti-tumor effect on human Burkitt lymphoma bearing nude mice, and down regulation of Raji induced BCL-2 cell apoptosis may be one of the inhibitory mechanisms of DC-CIK cells

ABSTRACT

Porcine epidemic diarrhea virus (PEDV) inhibits the host typeⅠinterferon and cellular antiviral response, but its inhibition mechanism is unclear, and the roles of PEDV nonstructural proteins in regulating typeⅠinterferon responses have been seldom studied. To study the effect of nsp1 on typeⅠinterferon response, nsp1 gene was cloned into a eukaryotic expression vector pCAGGS. The expression of nsp1 in transfected cells was determined by Western blot and indirect immunofluorescence assay. The effects of nsp1 on the induction of typeⅠinterferon were evaluated by dual luciferase reporter gene assay, ELISA and VSV bioassay. Western blot and indirect immunofluorescence assay showed that nsp1 was highly expressed in transfected cells and PEDV-infected cells. Dual luciferase reporter gene assay results indicated that nsp1 strongly inhibited the IFN-β promoter activity, and the inhibitory effect was nsp1 dose-dependent. ELISA results showed that nsp1 significantly inhibited the expression of IFN-β in protein level. And VSV replication-inhibition bioassay revealed that nsp1 significantly inhibited typeⅠIFN antiviral activities induced by poly(I:C). Our results implied that nsp1 was a highly conserved protein of PEDV and exhibited antagonistic function on interferon promoter activity. The results have laid a foundation for further understanding the immune evasion mechanism of PEDV and for developing new effective vaccine against PEDV.

ABSTRACT

Objective To investigate the influence and mechanism of erythropoietin (EPO) in renal blood flow after limb ischemia reperfusion (LIR). Methods Thirty male SD rats were randomly divided into control group, LIR group and EPO+LIR group with ten in each group. The values of renal blood flow, plasma creatinine (Cr), urea nitrogen (BUN) content in plasma, kidney tissue wet to dry ratio (W/D), nitric oxide (NO), nitric oxide synthase (NOS) and endothelin-1 (ET-1) in re-nal tissue were detected in three groups. The immunohistochemistry assay was used to detect the expression of intercellular adhesion molecule (ICAM-1) and vascular cell adhesion molecule (VCAM-1) in renal tissue. The morphological changes of renal tissue were observed with light microscope. Results The renal blood flow was significantly decreased, while the val-ues of Cr, BUN, W/D, NO, ET-1, NOS, expressions of ICAM-1 and VCAM-1 was significantly increased in LIR group than those of control group (P<0.05). Broaden interstitial and infiltration of inflammatory cells were observed in the renal tissue under light microscope. In the EPO+LIR group, the renal blood flow increased, the values of Cr, BUN, W/D, NO, ET-1 and NOS, expressions of ICAM-1 and VCAM-1 decreased significantly compared with those of LIR group (P<0.05). The patho-logical changes were alleviated in EPO+LIR group. Conclusion EPO can improve renal function, increase renal blood flow in rats after LIR. The mechanism may be related to the decreased edema, changed renal vasomotor function and decreased in-flammation.
