Objective:To systematically evaluate the correlation between chronic periodontitis and postmenopausal osteoporosis (PMOP).Methods:Electronic searches were conducted on Cochrane Library, Pubmed, Embase, Ovid, CNKI, CBM, VIP, and WF databases to collect research literature on the correlation between chronic periodontitis and PMOP. The Newcastle Ottawa Scale (NOS) criteria were used to evaluate the quality of the included literature, and RevMan 5.3 software was used for meta-analysis. The outcome measures were clinical attachment loss (CAL), probing depth (PD), plaque index (PI), calculus index (CI), bleeding on probing (BOP), and simplified oral hygiene index (OHI-S).Results:A total of 16 articles were included, with a total of 1587 patients. Compared with the postmenopausal non osteoporosis group, the osteoporosis group showed significant abnormalities in CAL [standardized mean difference (SMD)=1.09, 95% CI: 0.62-1.57, P<0.001], PD(SMD=0.71, 95% CI: 0.28-1.14, P<0.001), PI(SMD=0.43, 95% CI: 0.29-0.56, P<0.001), and OHI-S(SMD=0.28, 95% CI: 0.22-0.35, P<0.001) indicators, as well as in BOP(SMD=0.01, 95% CI: -0.48-0.49, P=0.97) and GI(SMD=0.01, 95% CI: -0.48-0.49, P=0.97). At the level of 0.24 and 95% CI: -0.34 to 0.81, P=0.42, there was no statistically significant difference. Conclusions:Women with PMOP exhibit more significant changes in indicators such as CAL, PD, PI, and OHI-S, suggesting that postmenopausal women with osteoporosis are more likely to suffer from periodontitis.

Purpose: Inflammatory myofibroblastic tumor (IMT) is a rare mesenchymal malignancy that occurs primarily in children and adolescents. The clinical and pathological features of IMT in adult patients are not well understood. Materials and Methods: We retrospectively searched for records of adult patients with IMT at Fudan University Shanghai Cancer Center from 2006 to 2021. Clinicopathological data, treatments, and outcomes were collected and analyzed. Results: Thirty adult patients with IMT, mostly women (60.0%), were included. The median age of the patients was 38 (21-77). The most common primary site was abdominopelvic region (53.3%), followed by lungs (20.0%). Seven patients had an abdominal epithelioid inflammatory myofibroblast sarcoma (EIMS). The positivity rate of anaplastic lymphoma kinase (ALK) was 81.5% (22/27). Sixteen patients with advanced ALK-positive disease received crizotinib, with an objective response rate (ORR) of 81.3% and a disease control rate of 87.5%. The median progression-free survival was 20.8 months. EIMS was associated with more aggressive behavior; however, the prognosis was similar to that of non-EIMS patients after treatment with an ALK inhibitor. At a median follow-up time of 30 months (95% confidence interval [CI], 13.6 to 46.4), the 5-year overall survival was 77% (95% CI, 66 to 88) in all patients. Conclusion Adult IMTs appeared more aggressive, with a higher incidence of recurrence and metastases, and patients with EIMS had more aggressive cases. Treatment with ALK inhibitors resulted in a high ORR and a durable response, which suggested that ALK inhibitors could be used as a first-line treatment option in adult patients with ALK-positive advanced IMT.

Objective:To explore the pathogenesis of major depressive disorder(MDD) by comparing the serum glucose and lipid metabolism indicators, levels of glucagon-like peptide-1(GLP-1) in plasma and feces, and the content of specific intestinal flora ( Lactobacillus, Bifidobacterium) between patients with MDD who were diagnosed for the first time and healthy controls. Methods:Totally 80 MDD patients hospitalized from January 1, 2020 to March 30, 2021 and 80 healthy volunteers with normal physical examination in the same period were selected. Blood and fecal samples of patients with MDD and healthy controls were collected respectively. The indicators of serum glucose and lipid metabolism were detected by automatic biochemical analyzer, the concentrations of GLP-1 in plasma and feces were detected by ELISA, and the relative contents of Lactobacillus and Bifidobacterium in feces were detected by real-time PCR. The differences between two groups of glucose and lipid metabolism indicators, GLP-1 levels and the relative contents of Lactobacillus and Bifidobacterium in feces were analyzed. SPSS 22.0 software was used for statistical analysis. Independent sample t-test and analysis of variance were used for inter group comparison, and Pearson correlation analysis was used for correlation analysis. Results:Compared with the control group, the levels of serum TC, HDL, and LDL in the MDD group decreased ((3.99±0.85)mmol/L , (4.78±0.86)mmol/L; (1.18±0.29)mmol/L, (1.30±0.28)mmol/L; (2.64±0.70)mmol/L, (3.19±0.69)mmol/L; t=5.559, 2.371, 4.695, all P<0.05). The plasma and fecal GLP-1 levels of the MDD group were lower than those of the control group (plasma: (0.81±0.22)pmol/mL, (1.05±0.26)pmol/mL , t=4.509, P<0.01; feces: (2.23±0.46)pmol/mL , (2.47±0.37)pmol/mL, t=2.533, P<0.05). Compared with the control group, the relative contents of Lactobacillus(2.56±1.59, 3.51±2.21) and Bifidobacterium(2.24±1.89 , 3.17±2.08) in the MDD group decreased ( t=2.218, 2.082, both P<0.05). The level of plasma GLP-1 in the MDD group was negatively correlated with FPG, TG, and disease severity ( r=-0.281, -0.221, -0.437, P<0.05). The level of plasma GLP-1 in the control group was negatively correlated with FPG ( r=-0.580, P<0.01). The fecal GLP-1 level of the MDD group was negatively correlated with the severity of the disease ( r=-0.298, P<0.01), and the fecal GLP-1 level of the control group was positively correlated with fecal Lactobacillus and Bifidobacterium ( r=0.685, 0.428, P<0.01). Conclusion:MDD patients have abnormal glucose and lipid metabolism, decreased GLP-1 level and decreased relative content of intestinal Lactobacillus and Bifidobacterium. Changes in intestinal flora affect GLP-1 levels. GLP-1 can affect glucose and lipid metabolism and depressive symptoms in patients with MDD by binding to specific receptors in intestinal tract and central nervous system.

Objective: To evaluate the association between NLRP2(NLR Family Pyrin Domain Containing 2) gene polymorphisms and classical type 1 diabetes mellitus(T1DM) in Chinese Han population. Methods: A case-control study was conducted in 510 classical T1DM patients from the Department of Metabolism and Endocrinology in the Second Xiangya Hospital affiliated to Central South University and 531 healthy controls in this region. The polymorphisms of rs1043673 in NLRP2 gene were analyzed by MassARRAY. Mann-Whitney U test and χ² test were used to compare the differences between patients and controls. Logistic regression analysis and χ² test were performed to compare the distributions of the alleles and genotypes between T1DM patients and controls. Kruskal-Wallis H test was used to compare the clinical characteristics of different genotypes in T1D patients. Results: The differences of the allele and genotype distributions in rs1043673 of NLRP2 gene were not significant between patients and controls. The polymorphisms of rs1043673 were associated with fasting C-peptide(P=0.029), postprandial 2-h C-peptide(P=0.017), and titer of GADA(P=0.043) in T1DM patients. Conclusion The polymorphisms of NLRP2 gene were associated with the characteristics of T1DM patients.

Objective:To evaluate the value of phase analysis of gated myocardial perfusion imaging (GMPI) in predicting major adverse cardiac events (MACE) in patients with coronary atherosclerotic heart disease.Methods:Patients who underwent two-day rest-stress GMPI in the Department of Nuclear Medicine of Beijing Hospital from September 2012 to January 2014 were selected as observed subjects and analyzed retrospectively. The general clinical information, GMPI images and related parameters including phase standard deviation (PSD), phase histogram bandwidth (PBW), entropy, left ventricular ejection fraction (LVEF), summed stress score (SSS), peak ejection rate (PER), peak filling rate (PFR) were noted. Patients were followed up until the onset of MACE (cardiac death, nonfatal myocardial infarction, and late revascularization within 60 d after GMPI). χ2 test, independent-sample t test or Wilcoxon rank sum test were used to compare data between different groups. The independent risk factors of MACE were obtained by Cox proportional risk regression model. Kaplan-Meier survival curve analysis was used to analyze the cumulative survival rate without MACE. Results:A total of 505 patients (235 males, 270 females, median age: 73 years) were followed up successfully, with a median follow-up period of 55.6(52.0, 60.5) months. There were 54 cases (10.7%) with MACE: 6 patients with cardiac death, 27 patients with non-fatal myocardial infarction, and 21 patients with late revascularization. The incidence of hypertension and hyperlipidemia in patients with MACE was significantly higher than that in patients without MACE ( χ2 values: 4.126, 6.021, both P<0.05); LVEF, PFR and absolute value of PER of patients with MACE were significantly lower ( t/ z values: 6.261, 5.683, -4.246, all P<0.05), while SSS, PSD, PBW and entropy were significantly higher ( t/ z values: 5.024, 5.874, 7.119, -6.405, all P<0.05). Cox proportional risk regression model showed that abnormal PBW(>80°), abnormal entropy(>58 J·mol -1·K -1) and SSS≥12 were independent risk factors for MACE (odds ratio( OR) values: 2.795(95% CI: 1.259-6.201), 3.213(95% CI: 1.468-7.029), 3.640 (95% CI: 1.999-6.628), all P<0.05). The 5-year cumulative MACE-free survival rates of abnormal PSD group(>26.7°), abnormal PBW group and abnormal entropy group were 51.2%, 63.2% and 46.7%, which were significantly lower than those of normal PSD group (92.3%; χ2=77.768, P<0.05), normal PBW group (94.2%; χ2=77.741, P<0.05) and normal entropy group (92.8%; χ2=117.437, P<0.05). The 5-year cumulative MACE-free survival rate (31.7%) of patients with abnormal PBW and SSS≥12 was significantly lower than that of patients with normal PBW or patients with abnormal PBW and SSS<12 (80.1%-94.4%; χ2=185.4, P<0.01). The combination analysis of entropy and SSS showed similar results. Conclusions:PBW and entropy obtained by GMPI phase analysis are independent risk factors for predicting MACE in coronary artery disease. GMPI phase analysis is useful for coronary artery disease risk stratification.

Objective: To investigate treatment option of inguinal lymph node metastasis after inguinal lymph node dissection in patients with penile cancer. Methods: To retrospectively analyze the efficacy and prognostic factors of cisplatin combined with fluorouracil in the concurrent chemoradiotherapy of inguinal lymph node metastasis after penile cancer surgery. Twenty-three patients with inguinal lymph node metastasis after inguinal lymph node dissection for penile squamous cell carcinoma from February 2009 to December 2015 were included.Inguinal lymph node metastasis with squamous cell carcinoma were confirmed by pathology or cytology. Metastatic lymph nodes of each patient were fixed, not less than 2, and greater than 4 cm in diameter. All patients received concurrent chemoradiotherapy with cisplatin and 5-fluorouracil.The response rate was evaluated after radiotherapy. The local control rate, survival time and the prognostic factors were also analyzed. Results: The median time of postoperative inguinal lymph node metastasis was 6.1 months, and the recurrence rate of the patients within 16 months after the operation was 95%.The response rate was 65.2% (15/23). After treatment, the local pain was significantly relieved and 7 cases of local hemorrhage was relieved. The 1-, 2-year survival rates were 21.3% and 5.5%, respectively, with a median survival of 6.3 months(95% CI: 3.4-8.1). And local tumor response rate correlated with radiation dose. Cox multivariate analysis showed that N staging and histological grade were independent prognostic factors for survival after treatment. Conclusions Concurrent chemoradiotherapy is effective for postoperative inguinal lymph node metastasis, especially for the local recurrence with symptoms and for patients who are not suitable for surgical salvage regarding the local tumor control, pain relief and tumor hemorrhage. However, the overall survival rate of the patients who received treatment was still low. Lower extremity edema is the main complication of concurrent chemoradiotherapy. N staging and poor differentiation of the tissue are unfavorable prognostic factors.

Objective: To investigate the efficacy and safety of albumin-bound paclitaxel in the treatment of advanced malignant tumors. Methods: Patients in advanced stage of cancer who had had drug-resistant relapse after receiving multiple-line treatment received chemotherapy with albumin-bound paclitaxel from May 2016 to April 2018 in Daxing Hospital of Capital Medical University. Their clinical data were collected to evaluate the treatment efficacy and safety profile. Results: 36 patients who had advanced treatment-resistent tumors with evaluable data were enrolled. Of 36 patients, 55.56% (20) had previously received chemotherapy with paclitaxel. The objective response rate (ORR) was 8.33%, the disease control rate (DCR) was 25.0%, the median progression free survival (PFS) was 106 days, and the median overall survival (OS) was 183 days. The main adverse reactions of grade 3-4 were hematological toxicity, including neutropenia [36.11% (13/36)], anemia and thrombocytopenia [5.56% (2/36) and 16.67% (6/36)] in patients without neutropenia fever. Adverse effects of 3-4 degrees related to non-hematologic toxicity were not observed. Conclusions Chemotherapy regimen with albumin-bound paclitaxel has certain efficacy for advanced malignant tumors resistant to multiple lines of therapy and the adverse effects could be generally tolerated.

Objective To explore the correlation between exon region polymorphism of PPP1R3A gene and schizophrenia in Uygur Chinese population. Methods PPP1R3A gene exon region DNA amplification was performed using multiple PCR targeted capture next-generation sequencing method in 528 patients with schizophrenia and 576 healthy controls of Uyghur descent, Illumina HiSeq X Ten was used for sequencing, the symptoms of schizophrenia were assessed by positive and negative symptoms scale (PANSS). Results The allelic and genotypic distributions in rs1800000 of PPP1R3A gene between patients with schizophrenia and healthy controls had significant difference (P＜0.05), rs1799999 in genotype frequency between the female case and control groups showed significant difference (P＜0.05). Furthermore, the allelic distributions of rs8192686 between male cases and controls had significant difference (P＜0.05). Conclusion PPP1R3A gene rs1800000 may be associated with the development of schizophrenia in Uygur Chinese population; rs1799999 may be a risk factor for susceptibility of female Uygur Chinese schizophrenia; The C allele at rs8192686 may be associated with male Uygur Chinese schizophrenia.

Objective: To evaluate the immunogenicity and safety of concomitant administration of 23-valent pneumococcal polysaccharide vaccine (PPV23) and trivalent influenza vaccine (TIV) in preschoolers. Methods: A total of 1 035 children aged 3-7 years were enrolled in this study and randomly divided into three groups, inoculated PPV23, TIV and both, respectively. A one-year follow-up study was conducted for immunogenicity and safety analysis. Results: A total of 1 035 serological specimens were collected, including 327 in PPV23 group, 348 in TIV group and 360 in concomitant vaccination group. No significant differences in geometric mean concentrations (GMC) of seven pneumococcal serotypes were observed between the PPV23 group and the concomitant vaccination group. Compared with the TIV group, the concomitant vaccination group showed higher serological conversion rate of H3 type (88.75% vs 84.20%, P=0.01), but lower serological conversion rate of B type (92.84% vs 98.56%, P<0.001). There was no significant difference in the primary adverse reactions between the three groups (P=0.197). The rate of secondary adverse reactions occurred in the concomitant vaccination group was 3.61%, which was higher than that of the other two groups (both P<0.001). All adverse reactions were mild or moderate, and cured after treatment. Conclusions Concomitant immunization with PPV23 and TIV is safe and have good immunogenicity, thus a viable immune strategy for susceptible children.

Objective To explore the clinical characteristics of acute calculous cholecystitis in over 80 years old patients.Methods A retrospective study was made on the clinical data of 71 cases diagnosed as acute calculous cholecystitis and receiving surgical treatment from Sep 2006 to Sep 2016.Patients were divided into three groups:Early LC group (25 patients),PTGD group (29 patients),the staged LC group (17 patients) after PTGD.Results There was statistically significant difference in the gallbladder wall thickness,operation time and blood loss between the two LC groups.There was no statistically significant difference between the two LC groups in other baseline data and hospital stay,hospital cost,rate of postoperational complication,rate of conversion to open procedure between the two LC groups.There was statistically significant difference between the early LC group and PTGD group in the baseline data.Logistic regression analysis indicated that the TG13 grade was an important influence factor for treatment selection of PTGD (OR=3.957,P=0.015,95％CI:1.30-12.043).Conclusion Laparoscopic cholecystectomy was safe for good risk over 80 years old patients.For poor risk patients,PTGD is recommended before a LC attempt.
