Objective To compare the efficacy and safety of remimazolam tosilate and propofol in painless ultrasonic gastroscopy. Methods In a randomized, single-blind controlled study, 60 patients undergoing ultrasonic gastroscopy were selected and divided into observation group (31 cases) and control group (29 cases). Observation group was anesthetized with remimazolam tosilate, while control group was anesthetized with propofol. Two groups' hemodynamic index, perioperative adverse events, changes of MOAA/S score, awakening and departure time were observed at different time points during anesthesia. Results The observation group had less changes on hemodynamics. The observation group had enough depth of sedation, while the control group had a deeper degree of sedation. The onset time of the two groups was similar and both awoke quickly and left, but the awakening time and leaving time in the observation group were slightly shorter. Adverse events in the control group were more than those in the observation group. Conclusions Remimazolam tosilate for painless ultrasonic gastroscopy had little effect on hemodynamics, which can generate enough depth of sedation, and make patients wake up quickly. In addition, the incidence of its adverse events was low, and the overall effectiveness and safety were superior to those of propofol.

Objective To evaluate the value of ultrasonography scoring system in differential diagnosis of well-differentiated liposarcomas (WDLPS) and benign lipoma (LP), and to provide evidence for the differential diagnosis and treatment choice. Methods Fourteen WDLPS cases (total of 15 masses) and 37 LP cases (total of 40 masses) were diagnosed by surgical histopathology, which clinical data and the ultrasound images were analyzed retrospectively. The parameters including age, gender, region, mass length, length/width ratio, shape, margin, envelope echoes, echogenicity, texture, location, blood flow were compared between the groups above. A scoring system was established by analyzing the parameters with statistical differences, and the ROC curve was plotted to calculate the best cut-off value and evaluate the diagnostic efficiency of the scoring system. Results There were statistically significant differences between two groups in the following six parameters: age, mass length, length/width ratio, envelope echoes, location, blood flow(P＜0.05). The scoring system was established by assigning 0 or 1 point to each factor, and the total score was 0～6 points. The highest diagnostic efficiency of WDLPS was observed at the cut-off value ≥ 3. The sensitivity, specificity, accuracy, the positive predictive value and the negative predictive value was 86.7%, 77.5%, 80%, 59.1%, 93.9% respectively. Conclusions The ultrasonography-based scoring system has a better diagnostic efficacy in differentiating WDLPS and LP, which can provide an important reference basis for the selection of clinical treatment, and is worthy of promotion and application.

Objective To investigate the relationship between intestinal flora-LPS-TLR4 pathway and the inflammatory injury of neonatal necrotizing enterocolitis (NEC). Methods Eleven neonates with NEC from March, 2019 to January, 2021 were enrolled as the experimental group, and 30 neonates without NEC and septicemia who were admitted in the department of neonatology in the same period were included as the control group. Faecal flora from the two groups were collected and analyzed by Real-time PCR. Toll-like receptor 4 (TLR4) and serum PCT, CRP, IL-6, SAA in peripheral blood were measured. The intestinal flora, the expression of TLR4 in peripheral blood leukocytes and inflammatory markers were compared between two groups. Results It showed that the ratio of Proteobacteria was 82% (9/11), Firmicutes was 9% (1/11), Actinobacteria was 9% (1/11) in the experimental group. In the control group, the ratio of Proteobacteria was 20% (6/30), Firmicutes was 73% (22/30), Actinobacteria was 7% (2/30). There was a significant difference in the distribution of faecal flora between the two groups (χ² = 11.521, P<0.05), and the level of TLR4 in peripheral blood of the experimental group was significantly higher than that of the control group (P＜0.001). The levels of serum PCT, CRP, IL-6 and SAA in the experimental group were significantly higher than those in the control group (P＜0.001).

Objective To explore the correlation between serum anti-Müllerian hormone (AMH) and 25(OH)D₃ levels in adolescent patients with polycystic ovary syndrome (PCOS). Methods Seventy-nine adolescent girls with PCOS and 85 non-PCOS healthy controls who walked in the gynecological clinic of our hospital from January 2019 to December 2020 were selected. Height, weight were measured and body mass index (BMI) was calculated.Hirsutism, acne and menstruation were evaluated by doctors on all subjects. Venous blood was drawn to detect levels of luteinizing hormone, follicle stimulating hormone, total testosterone, dehydroepiandrosterone sulfate, AMH and 25(OH)D₃, 25(OH)D₃ was further divided into insufficient [25(OH)D₃<30 ng/mL] and deficient [25(OH)D₃<20 ng/mL]level, then all data were compared and analyzed between two groups. Results Compared with the healthy control group, the PCOS group was more prone to have oligomenorrhea or amenorrhea, the incidence of acne was higher in PCOS group than in control group (all P values<0.05). BMI, the levels of AMH, total testosterone and dehydroepiandrosterone sulfate were significantly higher in the PCOS group compared to the control group, while 25(OH)D₃ was the opposite (all P values <0.05). AMH in the PCOS group was positively correlated with BMI and level of total testosterone, and negatively correlated with 25(OH)D₃ (all P values<0.05). The AMH level in the 25(OH)D₃ deficiency group was higher than that in the 25(OH)D₃ insufficient group, the AMH levels of the 25(OH)D₃ deficient group and control group were higher than that in the 25(OH)D₃ insufficient group,the differences were statistically significant (P<0.05). The 25(OH)D₃ deficiency rate in the healthy control group was 67.1% (57/85), while the 25(OH)D₃ deficiency rate in the PCOS group was 96.2% (76/79). The difference between the two groups was statistically significant (χ²=22.68, P<0.001). Conclusions Serum 25(OH)D₃ level was an independent factor significantly associated with AMH level in adolescents with PCOS. AMH and 25(OH)D₃ levels may be used as surrogate markers of PCOS risk in adolescents.

Objective To explore the value of preoperative ultrasound indicators in predicting the difficulty of laparoscopic cholecystectomy (LC), in order to predict the risk of LC surgery and reduce the blindness of surgery. Methods The preoperative ultrasonographic parameters of 257 cases included gallbladder size, gallbladder wall thickness, gallbladder mucosal surface, bile sound transmission in gallbladder, maximum diameter of gallstone, and gallstone incarceration in gallbladder neck. Postoperative data included operation time, intraoperative blood loss, whether drainage tube was placed, whether transfer to abdominal surgery, and postoperative complications. The average operation time of the 257 cases was calculated and called the standard operation time, and the operation that exceeded the standard operation time, intraoperative bleeding ≥100 mL, postoperative drainage tube placing, and conversion of abdominal operation were defined as difficult operation. According to this standard, 257 patients were divided into the easy group and the difficult group. The χ² test was used for univariate analysis to identify the risk factors of difficult LC operation. Logistic multiple regression analysis was performed to determine the independent risk factors for predicting LC difficulty. Results According to unifactor analysis, preoperative ultrasound indicators: gallbladder size >50 cm², gallbladder wall thickness >4 mm, maximum diameter of gallstone >2 cm, gallbladder neck stone incarceration, and poor bile ultrasound transmission in gallbladder were risk factors for LC difficulty. Logistic multiple regression analysis confirmed that gallbladder size, gallbladder wall thickness, poor bile ultrasound transmission in gallbladder and stone incarceration in gallbladder neck were independent risk factors for difficult LC. Conclusions Ultrasound examination of gallbladder before operation could objectively evaluate the difficulty of LC, and had certain predictive value for guiding the surgeon to select LC cases.

Objective To provide the reference for clinical rational use of aripiprazole,to investigate the effects of gender, age, daily dose, concurrent medication, drug manufacturer and other factors on the steady-state serum concentration in aripiprazole patients. Methods Serum concentration monitoring data of 229 inpatients using aripiprazole in Shenzhen Kangning Hospital from January 2019 to February 2021 was collected, including patients' gender, age, daily dose, concurrent medication, drug manufacturer and other basic information, which were retrospectively analyzed by SPSS 25.0 statistical software. Results In this study, only gender and daily dose could explain the significant changes of aripiprazole serum concentration after multiple linear regression analysis. The serum concentration/dose ratio (C/D) was significantly higher in female patients than in male patients (P＜0.01), and the group of aripiprazole combined with valproate was markedly higher than the non-combined group (P＜0.05). Nevertheless, there were no statistically significant differences in the effects of age, concurrent medication and drug manufacturer on aripiprazole C/D values. Conclusions The C/D value of aripiprazole was closely related to gender, and concurrent medication had a certain effect on it. There was no statistical difference in the aripiprazole C/D value among different drug manufacturers. This study suggested that clinical monitoring of therapeutic drugs should be strengthened, and the prescription should be optimized based on serum concentration and therapeutic efficacy, combined with pharmacoeconomic factors.

Objective The clinical characteristics of patients with influenza A in district hospital were analyzed to provide scientific basis for early diagnosis, prevention and control of influenza A in primary hospital. Methods A total of 628 patients with influenza-like symptoms from Guangzhou Panyu Central Hospital in December 2019 were enrolled, and the clinical data was collected, including gender, age, body temperature, symptoms, and blood test results. According to the result of influenza A nucleic acid detection, patients were divided into negative group and positive group, and the clinical data of these two groups were compared. Results A total of 116 patients were positive in influenza A virus nucleic acid detection, which positive rate was 18.5%. In the positive group, patients aged 14-19 accounted for the largest proportion, with 91 patients (78.4%). The mean age of the positive group was significantly lower than that of the negative group (P＜0.05). Body temperature ranged from 38.1 to 39 ℃ accounted for the largest proportion in the positive group, with 47 patients (46.5%). The mean body temperature of the positive group was significantly higher than that of the negative group (P＜0.01). In terms of symptoms, only the proportion of nasal congestion in positive group was higher than that in negative group (P＜0.05). In terms of blood test results, WBC count, neutrophil absolute value, lymphocyte absolute value and lymphocyte percentage in the positive group were significantly lower than those in the negative group (P＜0.01). Conclusions The majority of patients with influenza A in the winter of 2019 were teenagers, and it was difficult to distinguish influenza A from the common cold only by symptoms. The differential diagnosis should be carried out in combination with the blood routine analysis, especially the decrease in the white blood cell count, the absolute value of neutrophil and the absolute value of lymphocytes.

目的 回顾性分析CT血管成像(CTA)在急诊出血性脑卒中患者中,在病因诊断、病程进展评估中的应用。方法 89例头颅平扫初诊急性出血性脑卒中病人,行CTA检查,通过后处理技术,对各种出血原因进行影像学特征分析,并根据图像特征评估血肿的稳定性,在24小时内复查CT平扫了解出血的发展。结果 89例急诊脑出血患者,CTA检查中83例病因明确,并采取相应的临床处理。5例(5.6%)病因不明确,以蛛网膜下腔出血患者为主,需临床进一步全面检查。1例患者不配合造影检查失败。CT平扫发现不稳定血肿22例,复查血肿增大16例,准确率72.2%。CTA判断血肿内持续出血患者14例,复查13例患者有血肿增大,准确率为92.8%。结论 CT平扫只能评估血肿的稳定性,而CTA出现血肿内高密度影时,高度提示血肿内出血仍在持续。急诊医生可通过CTA对脑出血患者进行病因的分析、病程的预估、及时诊断、定位,对指导治疗及手术方式有重要作用。

Objective To retrospectively analyze the value of computed tomographic angiography (CTA) on etiological diagnosis and progression evaluation in patients with emergent hemorrhagic stroke. Methods Eighty-nine patients with preliminary diagnosis of acute hemorrhagic stroke underwent CTA, then various bleeding causes were analyzed by post-processing.The stability of hematoma was evaluated according to the image features.Follow-up CT in 24 h were performed to show the development of hemorrhage. Results In 89 cases of patients with emergent cerebral hemorrhage, 83 cases had made clear diagnosis according to CTA, then the patients received specialized clinical management.The causes of hemorrhage were not clear in 5 cases (5.6%), and subarachnoid hemorrhage was found in the most of these patients, requiring further examination.Twenty-two cases of unstable hematoma were found by CT scan, and hematoma enlarged in 16 cases in follow-up scan, with an accuracy of 72.2%.Fourteen patients were diagnosed as persistent bleeding hematoma by CTA, among them 13 patients showed hematoma enlargement, with an accuracy of 92.8%. Conclusions CT scan can only evaluate the stability of the hematoma, but the CTA high density in the hematoma strongly suggests persistent bleeding in the hematoma.Emergency doctors can analyze the cause of cerebral hemorrhage, assess the progression of disease, timely diagnose, locate the bleeding point by CTA, and there is important value in guidance of treatment and surgical methods.

Objective Using the TCGA database to explore the prognostic effects of DNA methylation sites on lung adenocarcinoma. Methods TCGA database was used to collecting DNA methylation data, gene expression data and clinical data of lung adenocarcinoma patients. The population were divided into the exploratory group and the validation group. The LASSO regression analysis was used to screen the methylation sites associated with the prognosis of lung adenocarcinoma in the exploratory group. Receiver operating characteristic curve was used to evaluate the prediction effect of the model, and further verified in the validation population. Results A total of 158 methylation sites with differential expression and significant correlation with the mRNA expression of the corresponding gene were screened from the TCGA database. With LASSO regression analysis, the DNA methylation sites associated with prognosis of lung adenocarcinoma were cg19378330. Those patients with levels above the median methylation site were assigned to the high-risk group, while those with levels below the median methylation site were assigned to the low-risk group. Patients' death risk in the high-risk group were 38% higher than those in the low-risk group (OR=1.38, 95%CI=1.16-2.69). The area under the curve was 0.80 (95%CI=0.73-0.88) and the sensitivity was 86.2% in the exploratory stage population.Similar results were seen in the validation population. Conclusions The DNA methylation site cg19378330 was significantly associated withthe prognosisof lung adenocarcinoma, and could effectively predict the risk of lung adenocarcinoma.

目的 系统评价胰岛素联用α-葡萄糖苷酶抑制剂(AGIs)治疗成人1型糖尿病(T1DM)的疗效和安全性。方法 检索中英文数据库,纳入关于胰岛素联用AGIs治疗成人T1DM患者的随机或非随机对照试验。使用Review Manager 5.3软件进行Meta分析。结果 共纳入10项研究,616例患者。与安慰剂或空白对照相比,在有效性方面,胰岛素联合AGIs可改善成人T1DM患者的糖化血红蛋白;降低平均血糖、空腹血糖和餐后2小时血糖;改善血糖波动情况,包括平均血糖波动幅度和最大血糖波动幅度(均P<0.05)。在安全性方面,AGIs增加总不良反应发生的风险(P<0.05),其中主要是胃肠道不适,但未增加低血糖的发生率和发生次数(均P>0.05)。胰岛素联合AGIs减少了每日胰岛素总剂量(P<0.05),但对体重、甘油三酯和高密度脂蛋白胆固醇无显著影响(均P>0.05)。结论 胰岛素联合AGIs可降低成人T1DM患者的糖化血红蛋白,改善血糖水平和血糖波动情况。AGIs不会增加低血糖的风险,但需重视其不良反应,特别是胃肠道不良反应。

Objective To systematically evaluate the efficacy and safety of adding alpha-glucosidase inhibitors (AGIs) to insulin therapy in adult patients with type 1 diabetes (T1DM). Methods Articles about randomized or non-randomized controlled trials of insulin combined with AGIs in adult patients with T1DM were retrieved from Chinese and English database. Meta-analyses were performed by using Review Manager 5.3. Results A total of 616 patients were included from 10 clinical trials. Compared with adding placebo or nothing, in terms of efficacy, the addition of AGIs resulted in decreased HbA1c, mean blood glucose, fasting plasma blood glucose and 2-hour postprandial blood glucose levels (all P<0.05). And this scheme improved the glucose variability including mean amplitude of glycemic excursions and the largest amplitude of glycemic excursions (P<0.05, respectively). As to safety, AGIs increased the risk of total adverse reactions (P<0.05), most of them were gastrointestinal complaints, while the occurrence and the frequency of hypoglycemia were similar (P>0.05, respectively). This scheme could also lead to the reduced total daily insulin dose (P<0.05) but had no significant effect on body weight, triglyceride or cholesterol concentration (P>0.05, respectively). Conclusions The addition of AGIs to insulin therapy in adult patients with T1DM may reduce HbA1c and improve the glucose levels and glucose variability. But total adverse effects especially the gastrointestinal complaints should also be considered in the use of AGIs although it does not increase the risk of hypoglycemia.
