Risk factors for complications of the retromandibular approach in patients with parotid gland posterior lower pole tumors / 中国医师杂志

Objective:To analyze the risk factors for complications of the retromandibular approach in patients with parotid gland posterior and lower pole tumors.Methods:A retrospective analysis was conducted on the clinical data of 140 patients with parotid posterior lower pole tumors admitted to the Xingtai Third Hospital from October 2019 to October 2021. They were divided into two groups based on whether complications occurred: the occurrence group and the non occurrence group. General data of the two groups of patients were collected, including age, gender, course of disease, previous surgical history, number of tumors, tumor length, resection range, facial nerve dissociation, tumor site resection frequency, and fascia preservation; Single factor and logistic multivariate analysis were conducted to determine the risk factors for complications of the posterior retromandibular approach in patients with parotid gland posterior and lower pole tumors.Results:A total of 140 patients with parotid gland posterior lower pole tumors underwent retromandibular approach treatment, with complications occurring in 38 cases (27.14%), including 7 cases of temporary facial paralysis, 10 cases of facial depression, 11 cases of Frey syndrome, 2 cases of fistula, and 8 cases of sensory abnormalities of the greater auricular nerve. Through logistic multivariate analysis, it was found that the number of tumors ≥ 2 ( OR=2.856), the resection range (total resection) ( OR=2.477), the number of surgeries ≥3 ( OR=5.637), facial nerve dissociation ( OR=3.526), and lack of fascia preservation ( OR=2.551) were all risk factors for postoperative complications in patients with parotid posterior pole tumors (all P<0.05). Conclusions:In clinical practice, relevant prevention and treatment measures should be formulated for these high-risk factors to reduce the incidence of postoperative complications.

Clinical evaluation of laboratory diagnosis of Mycoplasma pneumoniae / 中华实用儿科临床杂志

Objective:To compare the laboratory diagnostic methods of Mycoplasma pneumonia(MP) and evaluate its clinical value.Methods:A prospective study.Throat swabs and double sera of children with MP infection were collected from December 2016 to January 2017 in Shengjing Hospital Affiliated to China Medical University; throat swab samples of healthy children aged 3 to 5 in Chaoyang District, Beijing were collected from March to May 2017.Passive agglutination (PA) was used to detect the double serum.Taking the 4-fold increase or decrease of the specific antibody titer of the double serum as the gold standard, the receiver operating characteristic curve (ROC) was drawn, and the laboratory methods for detecting MP infection were compared and evaluated.Results:(1)A total of 93 children with MP infection were clinically diagnosed, including 42 males (45.2%) and 51 females (54.8%), with an average age of 5.5 years.Sixty cases (64.5%) of MP infection were diagnosed.There were 349 healthy children, 198 males and 151 females, with an average age of 4.3 years.The positive rate of throat swab culture was 0.6% (2 cases), and the positive rate of fluorescent quantitative PCR(qPCR) was 18.9% (66 cases). (2) The culture specificity was the highest (100.0%) and the sensitivity was the lowest (65.0%). PA and enzyme linked immunosorbent assay (ELISA) were used to detect a single serum in the acute phase, the sensitivity was 71.7% and 86.5% respectively.ROC curve suggested that the current clinical diagnostic threshold MP specific antibody IgM ≥ 1∶160 was not the best diagnostic threshold.Molecular biological diagnostic methods were the most sensitive, RNA simultaneous and testing (SAT) was 85.0% and qPCR was 93.0%; while the specificity was low, 75.7% (SAT) and 63.6% (qPCR), respectively.(3) At the same time, MP nucleic acid (SAT, PCR) of throat swabs and a single serum (ELISA, PA) of children in acute phase were detected, the sensitivity was increased to 95.0%-100.0%, and the specificity was 63.6%-75.7%.Conclusions:Molecular biology is highly sensitive in diagnosing MP infection.It has asymptomatic infection or is carried after infection.Whether it needs treatment needs to be combined with clinical practice, when MP detection is positive.The detection of a single serum in the acute phase with a course of about 1 week has high sensitivity and is of reference value for the diagnosis of MP infection, but the diagnosis needs to be combined with clinical practice.The sensitivity and accuracy of detecting MP infection by single serological test combined with SAT in acute phase are higher than that by single application.

Common bacteria in oropharynx of children with Mycoplasma pneumoniae pneumonia and its clinical significance / 中华实用儿科临床杂志

Objective:To investigate the common bacteria in the oropharynx of children with Mycoplasma pneumoniae pneumonia (MPP) and its clinical significance.Methods:A total of 134 children with MPP who were hospitalized in the Department of Pediatric Respiratory, Shengjing Hospital of China Medical University from December 2016 to June 2017 were selected as the research subjects, and 42 healthy children in the same hospital were selected retrospectively as the healthy control group during the same period.Fluorescent quantitative polymerase chain reaction Taqman probe was used to detect common oropharyngeal bacteria[ Streptococcus pneumoniae(SP), Moraxella catarrhalis(CTA), Haemophilus influenza(HI)] for the enrolled children.Firstly, the bacterial detection rate of MPP children and healthy children was compared.Then, according to age(<1 years old, 1-<3 years old, 3-<6 years old and 6-14 years old), bacterial detection[Mycoplasma pneumoniae(MP), MP+ bacteria]and bacterial species(MP+ SP, MP+ CTA, MP+ HI), 134 children with MPP were divided into groups to compare.Moreover, the relevant clinical datas were retrospectively analyzed by rank sum test and chi- square test. Results:Among 134 children with MPP, 79 (58.96%) children were detected bacteria, and 17 (40.48%) children were detected bacteria among 42 healthy children, with statistically significant differences( χ2=4.404, P<0.05). Compared with the MP group, the level of white blood cell (WBC)[8.5(6.7, 12.0)×10 9/L vs.7.8(5.8, 9.3)×10 9/L, Z=-2.232], C reactive protein(CRP)[19.2(7.2, 35.0) mg/L vs.8.4(3.4, 24.6) mg/L, Z=-2.810], lactate dehydrogenase(LDH)[286(244, 365) U/L vs.250(210, 302) U/L, Z=-2.474] and the incidence of lobar pneumonia[40.51%(32/79 cases) vs.18.18%(10/55 cases), χ2=7.510], pleural effusion[13.92%(11/79 cases) vs.3.64%(2/55 cases), χ2=3.917], refractory Mycoplasma pneumoniae pneumonia (RMPP)[34.18%(27/79 cases) vs.18.18%(10/55 cases), χ2=4.151] in MP+ bacteria group were higher; the course of fever[10(7, 12) d vs.8(6, 10) d, Z=-2.706] and duration of antibiotic use[16(13, 19) d vs.12(9, 16) d, Z=-3.747] in MP+ bacteria group were longer (all P<0.05). The level of WBC in MP+ SP group[12.20(7.80, 17.30)×10 9/L] was higher than that in MP+ HI group [6.75(5.37, 9.44)×10 9/L], and the differences were statistically significant( Z=11.574, P<0.05), and the incidence of lobar pneumonia in MP+ SP group [56.67%(17/30 cases)]was higher than that in MP+ CTA group [0(0/3 cases)]and MP+ HI group[18.75%(3/16 cases)], and the differences were statistically significant( χ2=9.770, P<0.05). Conclusions:Bacterial colonization or infection is more likely to occur in the oropharynx of children with MPP.When WBC, CRP, and LDH are significantly increased and the image shows a large consolidation or pleural effusion, it may indicate mixed bacterial infection, longer course of fever and higher incidence of RMPP, and the common mixed bacteria is SP.

The study of comparing three different cannula operations for peritoneal dialysis / 中华危重病急救医学

Objective:To observe the clinical effect of the cannula under laparoscopy, percutaneous puncture cannula, and conventional surgery cannula for peritoneal dialysis.Methods:From May 3, 2015 to February 14, 2020, 87 patients with end-stage renal disease needing peritoneal dialysis in Ningbo Zhenhai People's Hospital were enrolled. These patients were divided into three groups including cannula under laparoscopy (23 cases), percutaneous puncture cannula (29 cases), and conventional surgery cannula (35 cases). The baseline characteristics, perioperative conditions (surgical time, post-surgical hospitalization time), the incidence of recent complications (abdominal hemorrhage, direct abdominal hemorrhage, incision pain, leakage, catheter shift, peritonitis), and long-term complications (catheter shift, peritonitis, hernia, thoracic and abdominal fistula, abdominal tube obstruction) among the three groups were compared.Results:Compared with the group of conventional surgery cannula, the operation time in the group of cannula under laparoscopy and the group of percutaneous puncture cannula were significantly shorter (minutes: 32.5±12.3, 28.9±11.8 vs. 61.3±15.4, both P < 0.05), the in-hospital stay in the group of cannula under laparoscopy and the group of percutaneous puncture cannula were reduced (days: 9.8±3.4, 9.2±2.6 vs. 10.7±3.2), but there was no statistical significance among the three groups ( P > 0.05). The incidence of abdominal bleeding, rectus abdominis bleeding, and incision pain in the group of cannula under laparoscopy and the group of percutaneous puncture cannula were significantly lower than those in the group of conventional surgery cannula [incidence of abdominal bleeding: 4.3% (1/23), 3.4% (1/29) vs. 22.9% (8/35), incidence of rectus abdominis bleeding: 4.3% (1/23), 3.4% (1/29) vs. 22.9% (8/35), incidence of incision pain: 8.7% (2/23), 10.3% (3/29) vs. 42.9% (15/35), all P < 0.01]. The difference between the group of cannula under laparoscopy and the group of percutaneous puncture cannula had no statistical significance. Compared with the group of conventional surgery cannula and the group of percutaneous puncture cannula, the incidence of catheter displacement in the group of cannula under laparoscopy was significantly reduced [4.3% (1/23) vs. 27.6% (8/29), 31.4% (11/35), both P < 0.05]. Compared with the group of conventional surgery cannula and the group of percutaneous puncture cannula, the incidence of catheter displacement in long-term complications in the group of cannula under laparoscopy was significantly reduced [4.3% (1/23) vs. 24.1% (7/29), 31.4% (11/35), both P < 0.05], however, the difference of that between the group of conventional surgery cannula and the group of percutaneous puncture cannula was not statistically significant. The incidence of hernia in the group of cannula under laparoscopy was significantly higher than that in the group of percutaneous puncture cannula or in the group of conventional surgery cannula [21.7% (5/23) vs. 3.4% (1/29), 2.8% (1/35), both P < 0.05], and all of that were umbilical hernia, however, the difference of that between the group of percutaneous puncture cannula and the group of conventional surgery cannula was not statistically significant. Conclusion:Compared with the traditional conventional surgical cannula placement methods, percutaneous puncture has the advantages of simple operation, short operation time, small trauma, but still cannot reduce the incidence of drift tube; laparoscopic peritoneal dialysis tube has the advantages of short operation time, small trauma and low catheter displacement rate, but increases the risk of umbilical hernia.

Clinical characteristics and risk factors for plastic bronchitis caused by severe mycoplasma pneumonia in children / 中国小儿急救医学

Objective:To summarize the clinical characteristics of plastic bronchitis caused by severe mycoplasma pneumoniae pneumonia in children, to find the risk factors for plastic bronchitis, and to provide references for judging the prognosis and comprehensively formulating treatment plans.Methods:We retrospectively analyzed the clinical data(146 cases)of children with severe mycoplasma pneumoniae pneumonia who underwent bronchoscopy in the Department of Pediatric Respiratory Medicine of Shengjing Hospital of China Medical University from January 2017 to December 2019.According to whether it was plastic bronchitis, all patients were divided into plastic bronchitis group(68 cases) and non-plastic bronchitis group(78 cases), and the gender, age, laboratory examination indicators, imaging characteristics and treatment of children were collected under the circumstances.The single factor with clinical significance and statistical significance would be subjected to multivariate Logistic regression analysis.Results:There were no significant differences in gender, age, heat duration, white blood cell count, C-reactive protein value, and interleukin-6 value between the two groups(all P>0.05). The percentage of neutrophils, alanine aminotransferase, aspartate aminotransferase, lactate dehydrogenase, D-dimer, number of cases of pleural effusion, length of hospital stay, and number of endoscopy in the plastic bronchitis group were higher than those in non-plastic bronchitis group, the number of right upper lobe consolidation cases was less than that in the non-plastic bronchitis group, and the differences were statistically significant( P<0.05). Multiple Logistic regression analysis showed that pleural effusion( OR=4.898, 95% CI 2.195-10.926) and lactate dehydrogenase ( OR=1.051, 95% CI 1.003-1.101) were independent predictors of plastic bronchitis in children with severe mycoplasma pneumoniae pneumonia. Conclusion:For children with severe mycoplasma pneumoniae pneumonia, if lung CT shows that the upper lobe of the non-right lung is uniformly compacted and complicated with pleural effusion, lactate dehydrogenase is significantly increased, and attention should be paid to the possibility of plastic bronchitis.Timely improvement of fiberoptic bronchoscopy may shorten the course of the disease and reduce the occurrence of complications.

Objective:To explore the clinical characteristics of children with atopic mycoplasma pneumoniae pneumonia and to provide evidence for the diagnosis and treatment of children with atopic mycoplasma pneumoniae pneumonia.Methods:One hundred and eighty cases of children diagnosed with mycoplasma pneumoniae pneumonia in Shengjing Hospital of China Medical University from January 2018 to December 2018 were selected. According to whether they had atopic constitution, they were divided into atopic mycoplasma pneumoniae pneumonia(AMPP)group(84 cases)and non-atopic mycoplasma pneumoniae pneumonia(NAMPP)group(96 cases). The clinical data of age, sex, fever time, hospital stay, application time of macrolides, white blood cells, CRP, LDH, and lung CT were collected from the two groups, and the differences in clinical manifestations, laboratory examinations and imaging manifestations of the two groups were analyzed retrospectively.Results:(1)Both the absolute value of eosinophils and total IgE values in the AMPP group were higher than those in the NAMPP group, and the difference was statistically significant( P<0.05). The incidence of severe mycoplasma pneumoniae pneumonia(SMPP)and/or refractory mycoplasma pneumoniae pneumonia(RMPP)and chest imaging manifestations of interstitial pneumonia in the AMPP group was higher, and the difference was statistically significant( P<0.05). (2)The incidence of wheezing in the AMPP group was 48.81%(41 cases/84 cases), which was significantly higher than that in the NAMPP group 22.92%(22 cases/96 cases). The duration of cough and wheezing in the AMPP group was longer than that in the NAMPP group( P<0.05), with statistically significant differences( P<0.05). (3)In the AMPP group, 36.90%(31 cases /84 cases)of the children received intravenous methylprednisolone treatment, which was significantly higher than the 20.83%(20cases /96 cases)of the NAMPP group. Lung rales absorption time in the AMPP group[(9.73±3.59)d] was significantly longer than that in the NAMPP group[(7.52±2.44)d], and the difference was statistically significant( P<0.05). Lung CT examination showed that the absorption of lung inflammation in the AMPP group was worse than that in the NAMPP group, with a statistically significant difference( P<0.05). The hospitalization time of children in the AMPP group[(10.88±4.17)d] was longer than that in the NAMPP group[(9.68±2.68)d], with a statistically significant difference( P<0.05). Conclusion:The condition of AMPP is more serious than that of NAMPP, and it is more likely to cause incomplete absorption of pulmonary inflammation.

Research on Cardiac Structure and Function in the Overweight and Obese population and Influence Factors / 生物医学工程学杂志

In this study we performed Tissue Doppler Imaging (TDI), two-dimensional speckle tracking imaging (2D- STI) and three-dimensional speckle tracking imaging (3D-STI) on enrolled healthy, overweight and obese groups (34 subjects in each group), respectively, to analyze cardiac structure and its function. Compared with healthy group, global longitudinal strain (GLS), global circumferential strain (GCS), global area strain(GAS) and global radial strain (GRS) decreased progressively (P < 0.05). The ratio of early diastolic mitral inflow velocity to global early diastolic strain rate of left ventricle (E/e'sr) (r = 0.466, P < 0.001), GLS (r = 0.502, P < 0. 001), GCS (r = 0.426, P < 0.001), GAS (r = 0.535, P < 0.001) and GRS (r = -0.554, P < 0.001) were correlated with body mass index (BMI). E/e'sr (r = 0.37, P = 0.003), GLS (r = 0.455, P < 0.001), GCS (r = 0.282, P = 0.02), GAS (r = 0.412, P < 0.001) and GRS (r = -0.471, P < 0.001) were correlated with free fatty acid (FFA). Stepwise multiple linear regression revealed that BMI was independently correlated with E/e'sr, GLS, GCS, GAS and GRS. Waist to hip ratio (WHR) was independently correlated with GLS, GCS, GAS and GRS. FFA was independently correlated with E/e'sr (P < 0.05). The study showed that cardiac structure changed and impaired left ventricular global systolic and diastolic function in overweight and obes population. Moreover, BMI, WHR and FFA may be independent influence factors of cardiac function in overweight and obese population.

Two tooth preparation methods to make glass fiber splints for stabilizing loose front teeth:A 5-year clinical observation / 中国组织工程研究

BACKGROUND:Studies have found that the glass fiber splint which is embedded into the groove on the lingual surface of the affected tooth plus fluid resin fixation between the gap of mobile teeth can achieve more satisfactory clinical effects on the stabilization of loose front teeth. OBJECTIVE:To observe the clinical effects of glass fiber splints prepared using two tooth preparation methods on splinting loose front teeth and their debonding rate through a 5-year fol ow-up visit. METHODS:Ninety-four chronic periodontal disease patients, who had received periodontal treatment, were enrol ed in this study for their loose front teeth of degree II-III. Al the enrol ed patients were good candidates for periodontal splinting strictly in accordance with the indications for periodontal splinting. According to whether the fluid resin was used to seal the gap between the mobile teeth, the 96 patients were divided into two groups:patients undergoing glass fiber splint+fluid resin between the mobile teeth served as experimental group, and those only undergoing glass fiber splint as control group. Al the patients were fol owed by regular clinical referral or telephone fol ow-up for 5 year, to evaluate the fixed effects. RESULTS AND CONCLUSION:During the 5 years of regular clinical referral or telephone fol ow-up, seven of the 76 cases and 12 of the 18 cases were found in the experimental and control groups, respectively, to have debonding between the abutment and the splint. Compared with the control group, the probing depth and attachment loss of affected teeth were improved significantly (P<0.05), and the percentage of alveolar bone height accounting for the root length increased significantly in the experimental group (P<0.05) after 5 years of fol ow-up. Patients in the experimental group felt comfortable without foreign body sensation. The results confirmed that the glass fiber splinting plus fluid resin fixation between the gap of mobile teeth was a better treatment for loose front teeth during the 5-year fol ow-up.

Meta analysis of the efficacy and safety of combined treatment with ARB and ACEI on diabetic kidney disease / 中南大学学报(医学版)

OBJECTIVE@#To evaluate the efficacy and safety of combined treatment with angiotensin II receptor blocker (ARB) and angiotensin converting enzyme inhibitor (ACEI) on diabetic kidney disease.@*METHODS@#Randomized controlled trials (RCTs) were identified from CoChrane library, PubMed, EMbase, CNKI and VIP. Eleven RCTs involving 602 patients were included and analyzed with Rev Man 5.1 software.@*RESULTS@#Compared with ACEI alone, combined treatment with ARB and ACEI was more effective on decreasing 24 h albuminuria, systolic pressure, average 24 h systolic pressure, diastolic pressure, and average 24 h diastolic pressure but with a high level of serum potassium. Compared with ARB alone, combined treatment with ARB and ACEI was more effective on decreasing systolic pressure and diastolic pressure. Compared with ACEI or ARB alone, we didn't get a definite conclusion that whether combined treatment with ARB and ACEI was more effective on decreasing 24 h proteinuria.@*CONCLUSION@#Based on this Meta analysis, combined treatment with ARB and ACEI is safer and has positive effect on diabetic kidney disease. However, small sample size and low methodological quality appeared in most of the trials included in this systematic review. Therefore, available evidence is insufficient to recommend a routine clinical application of combined treatment with ARB and ACEI on diabetic kidney disease.

Effect of Aspirin on the Expression of Hepatocyte NF-kappaB and Serum TNF-alpha in Streptozotocin-Induced Type 2 Diabetic Rats

Aspirin is a kind of anti-inflammatory drug and may be used to reverse hyperglycemia, hyperinsulinemia, and dyslipidemia by improving insulin resistance. We hypothesized that aspirin improves insulin resistance in type 2 diabetes by inhibiting hepatic nuclear factor kappa-beta (NF-kappaB) activation and serum tumor necrosis factor-alpha (TNF-alpha). Adult male Wistar rats were randomly divided into four groups: control, untreated diabetic, diabetic treated with metformin (100 mg/kg/day), and diabetic treated with aspirin (120 mg/kg/day). Diabetes was induced by high-fat feeding and a low dose of streptozotocin (30 mg/kg). After treatment, plasma glucose, insulin, lipids, free fatty acids (FFAs) concentrations and serum TNF-alpha were determined. The expression of NF-kappaB in hepatocytes was analyzed by immunohistochemistry and western blot. The results showed administration of aspirin caused no significant lowering in fasting glucose level but significant reduction of hepatic NF-kappaB expression and serum TNF-alpha level with improved insulin resistance compared to the diabetic group. The relevant analysis showed positive correlation between the expression of homeostasis model assessment-insulin resistance (HOMA-IR) and NF-kappaB (r = 0.799, P < 0.01); HOMA-IR and serum TNF-alpha (r = 0.790, P < 0.01). It is concluded that aspirin improves insulin resistance by inhibiting hepatic NF-kappaB activation and TNF-alpha level in streptozotocin-induced type 2 diabetic rats.

Inhibitory effect of cochinchina momordica seed ethanol extract on proliferation of melanoma B16 cells and its possible meachanism / 中国肿瘤生物治疗杂志

Objective: To investigate the effect of cochinchina momordica seed ethanol extract (CMSEE) on the proliferation of melanoma B16 cells and the underlying mechanism. Methods: MTT and clone formation assay were used to assess the effect of CMSEE on the growth of B16 cells. Morphological changes of B16 cells were observed under phase-contrast microscope and Giemsa staining. Cell cycle and apoptosis rate were examined by flow cytometry (FCM). The effect of CMSEE on melanin production and tyrosinase activity of B16 cells was assessed by colorimetry. The effect of CMSEE on the expression of C-myc, P38, and Tyr genes was examined by RT-PCR. Results: CMSEE (10-100 mg/L) inhibited the proliferation of B16 cell in a dose-and time-dependent manner. After treatment with 10-40 mg/L CMSEE, B16 cells showed typical differentiation morphology, and melanin production and tyrosinase activity were increased. B16 cells treated with 100 mg/L CMSEE showed apoptotic morphology, decreased melanin production and tyrosinase activity. B16 cell number in G_0/G_1 phase was significantly increased (P<0.01); C-myc mRNA expression was down-regulated, and P38, Try mRNA expression was up-regulated in B16 cells after treatment with 10-40 mg/L CMSEE. Conclusion: CMSEE can markedly inhibit the proliferation of melanoma B16 cells, which is related to induction of differentiation and promotion of apoptosis of B16 cells.
