Objective To investigate the influence of Chinese medicine ( CM) treatment on life span of middle-late primary hepatic carcinoma (PHC) patients. Results A multicenter retrospective cohort study was carried out in 489 PHC patients at the stages of Ⅱb, Ⅲa and Ⅲb collected from 15 domestic hospitals. With CM treatment as the exposure factor, the enrolled patients were divided into CM group, western medicine (WM) group and the CM-WM combination group. The main outcomes included median survival time (MST) and survival rate, and the effects of CM treatment and minimally invasive therapy on MST were observed. Results Half-a-year survival rate, one-year survival rate and two-year survival rate were 50%, 9%, 1% in CM group, 70%, 30%, 6% in CM-WM combination group, and 50%, 10%, 0% in WM group, respectively. The survival rates in CM-WM combination group differed from those in CM group and WM group (P<0.01), but the differences of survival rates between CM group and WM group were insignificant (P>0.05) . MST at the stages of Ⅱb, Ⅲa, Ⅲb in CM-WM group was obviously prolonged as compared with the other two groups (P<0.01), and MST at the stages of Ⅲa, Ⅲb in CM group was also obviously prolonged as compared with WM group (P<0.05) . The difference of MST at the stage of Ⅱb was insignificant between CM group and WM group ( P>0.05) . CM treatment and minimally invasive therapy were effective on prolonging the survival time of PHC patients ( P<0.01) . The results of COX regressionanalysis showed that Karnofsky scores, CM treatment and minimally invasive therapy were the preventive factors for the prognosis. Conclusion CM-WM combination group has the best long -term therapeutic effect. CM -WM combination treatment is effective on increasing MST and long-term survival rate, in particular for PHC patients at the stages ofⅡb, Ⅲa and Ⅲb. CM treatment and minimally invasive therapy are helpful for the prolongation of the survival time of PHC patients.

Objective:To explore the application effect of video education combined with Teach-back in the treatment of patients with chronic periodontitis.Methods:Using non-simultaneous experimental research methods, From January to August in 2019, 41 patients with chronic periodontitis who underwent implant restoration in Shanghai Tenth People′s Hospital was selected by convenience sampling method as the control group, and implemented routine oral health education. From September 2019 to May 2020, 42 patients with chronic periodontitis who underwent implant restoration in Shanghai Tenth People′s Hospital were the observation group, and implemented video education combined with Teach-back. Compare the two groups of oral health care self-efficacy, periodontal clinical indicators, and the incidence of peri-implant mucositis.Results:Comparing 6 months and 12 months after implant restoration, the total scores of oral health self-efficacy and regular oral visits, correct brushing, and balanced diet in the observation group were 66.31 ± 4.32 and 67.19 ± 4.65, 22.04 ± 1.35 and 21.69 ± 1.82, 21.73 ± 1.65 and 22.64 ± 1.82, 22.54 ± 1.62 and 22.86 ± 1.74 respectively, which were higher than the control group 53.93 ± 4.78 and 54.09 ± 5.67, 17.02 ± 2.58 and 17.43 ± 2.16, 17.65 ± 1.74 and 18.54 ± 2.36, 19.14 ± 2.13 and 18.12 ± 2.58, the difference between the two groups at the two time points were statistically significant ( t values were 6.52-12.39, all P<0.05). And the PLI, mSBI, and PIS scores of the observation group were 0.80 ± 0.17 and 0.75 ± 0.14, 0.79 ± 0.19 and 0.81 ± 0.18, 2.08 ± 0.45 and 2.10 ± 0.53, respectively, which were lower than the control group 0.92 ± 0.19 and 0.99 ± 0.21, 1.03 ± 0.17 and 1.16 ± 0.21, 2.45 ± 0.68 and 2.62 ± 0.61, the difference between the two groups at the two time points were statistically significant ( t values were 2.93-8.16, all P<0.05). 12 months after, the incidence of mucositis around implants in the observation group was 7.14%(3/42), which was lower than 26.83%(11/41)in the control group ( χ2=5.73, P<0.05). Conclusions:Video education combined with Teach-back can improve the self-efficacy of oral health care during implant restoration treatment in patients with chronic periodontitis, improve oral health care behavior, thereby improving the periodontal condition around the implant and reducing the incidence of mucositis.

OBJECTIVEHuman leukocyte antigen (HLA) class II genes, especially HLA-DQ genes, which are highly polymorphic, have been thought to be candidate loci for the etiology of asthma, and shown to be involved in antigenic presentation. This study was conducted to investigate whether susceptibility or resistance to asthma is associated with HLA-DQA1 and DQB1 genes polymorphism.

METHODSVenous blood samples were collected from northern Chinese population with Han ethnic. (1) One hundred and twenty-five unrelated asthmatic individuals and 52 subjects from 12 asthmatic pedigrees. (2) Ninety-six healthy controls without asthma and atopy with the same ethnic. Genomic DNA was extracted using standard phenol-chloroform method. The second exon of HLA-DQA1 and DQB1 genes were amplified by sequence-specific primer-polymerase chain reaction (SSP-PCR) method. All asthmatics had their serum IgE (total and specific) antibody or skin-prick test measured, bronchial reactivity to methacholine (Mch) and bronchial reversibility by beta(2)-agonist evaluated.

RESULTSHLA-DQA1 * 0104 allele and HLA-DQB1 * 0201 allele were significantly higher in asthmatics than those in healthy controls (0.408 vs 0.177, P < 0.01; 0.568 vs 0.198, P < 0.01). Odds ratios (ORs) were 3.203 (95% CI 1.699 - 6.037), 5.328 (95% CI 2.883 - 9.849) respectively. Conversely, HLA-DQA1 * 0301 allele and HLA-DQB1 * 0301 were significantly decreased in asthmatics compared to healthy controls (0.296 vs 0.50, P < 0.01; 0.4 vs 0.563, P < 0.05); Logistic regression analysis showed that HLA-DQA1 * 0104 allele was associated independently with asthma etiology, OR [represented by Exp(B)] was 5.0942 with 95% CI 2.2520 - 21.1813; Spearman's analysis showed that HLA-DQA1 * 0104 allele and HLA-DQB1 * 0201 allele were positively associated with atopy, the correlation coefficient were 0.183 and 0.289 respectively, P < 0.01. By contrast, HLA-DQA1 * 0301 allele was negatively related to atopy, the correlation coefficient was -0.168, P < 0.05; linkage analysis did not support the view that HLA-DQA1/DQB1 genes were linked to asthma with LOD value being 0.72.

CONCLUSIONSHLA-DQA1 * 0104 allele and HLA-DQB1 * 0201 allele were implicated in susceptibility to asthma and atopy, HLA-DQA1 * 0301 allele and HLA-DQB1 * 0301 might be protective factor against asthma. Asthma and atopy are multifactorial disorders, HLA-DQA1 and DQB1 genes are involved in the regulation of immune specific response to common allergen.

Objective·To investigate the potential causal relationship between type l diabetes and colorectal cancer by using Mendelian randomization(MR).Methods·Two-sample bidirectional MR was used to investigate the causal relationship between type 1 diabetes and colorectal cancer.All research data were collected from the IEU Open GWAS Project database.The dataset of type l diabetes included 9 266 cases and 15 574 controls,with correlation analysis in 12 783 129 single nucleotide polymorphisms(SNPs);the dataset of colorectal cancer included 5 657 cases and 372 016 controls,with correlation analysis in 29 999 696 SNPs.The instrumental variables SNPs were screened.The results derived from the inverse-variance weighted(IVW)method were used as the main indicator of effect.The results derived from other four methods,namely MR-Egger regression,weighted median,simple mode,and weighted mode,were used as reference.Sensitivity was analyzed with the leave-one-out method.Heterogeneity was analyzed with Cochran's Q test by using both IVW and MR-Egger methods.Pleiotropy was analyzed with MR-pleiotropy function,and Steiger test was used for directional research.The colocation analysis was used to find out whether the causal relationship between type 1 diabetes and colorectal cancer was caused by the same SNP.The genetic correlation between 2 diseases was analyzed by using the linkage disequilibrium score regression(LDSC).All tests were analyzed by using R language software(version 4.3.1).Results·After being screened,a total of 33 instrumental variables(SNPs)were used.The heterogeneity test results showed that there was heterogeneity among the SNPs(IVW and MR-Egger:P＜0.05),so the effect evaluation was based on the results of the random effect model.MR analysis showed that type 1 diabetes had a significant causal effect on colorectal cancer(P＜0.05)by using IVW,MR-Egger,weighted median and weighted mode.Sensitivity analysis showed that the results were stable.Pleiotropy was not detected in pleiotropy test(P＞0.05).Steiger test showed that the effect of type l diabetes on colorectal cancer was not interfered with by the reverse effect.Reverse MR analysis showed no causal effect of colorectal cancer on type l diabetes(P＞0.05).The results of colocalization analysis showed that the probability of H4 hypothesis was 45.7％,and the causal relationship between the 2 diseases was not caused by the same SNP in the gene sequences.LDSC analysis demonstrated that there was no genetic correlation between the two diseases.Conclusion·Type 1 diabetes may promote colorectal cancer,but colorectal cancer has no effect on type 1 diabetes.

Objective:To enhance the early recognition of Prader-Willi syndrome by summarizing the clinical characteristics of Prader-Willi syndrome (PWS) during perinatal period.Methods:Through a nationwide cross-sectional study in the Department of Pediatrics, Peking Union Medical College Hospital, Peking Union Medical College, Chinese Academy of Medical Sciences,226 children diagnosed as PWS by molecular genetics were recruited from September 2019 to March 2020. Clinical data including fetuses Age, birth weight, fetal movement, fetal position, amniotic fluid, mode of bith, crying, muscle tension, feeding, and cryptorchidism were collected to analyze the clinical characteristics of Chinese PWS patients in the perinatal period, and according to the mode of birty, birth weight and genotypes to perform subgroup analysis. The clinical manifestations of different subtypes were statistically analyzed by t test, χ 2 test or Mann-Whitney U test. Results:Among the 226 PWS patients, 120 were males, and 106 were females. Among them, 100 (44.2%) patients were small for gestational age. Decreased fetal movement was the most common manifestation 202 cases (89.4%) during pregnancy, and other manifestations included polyhydramnios 71 cases (31.4%) and abnormal fetal position 58 cases (25.7%). One hundred and eighty-five (81.9%) patients were delivered by cesarean section and the frequency of abnormal fetal position was significantly higher (30.8%(57/185) vs. 2.4%(1/41),χ2=14.161, P<0.01). As for abnormal manifestations after birth included hypotonia 221 cases (97.8%),220 cases (97.3%) showing weak crying, 116 cases among the total 120 males patients (96.7%) wanifested with cryptordnildism and 206 feeding difficulties (91.2%). In terms of genetic subtype, most of them (184/226, 81.4%) had a paternal deletion, while maternal age (35±5 vs. 29±5, t=-6.591, P<0.01) and the frequency of polyhydramnios (47.6% (20/42) vs. 27.7% (51/185), χ2=6.286, P=0.012) were significantly higher in the non-deletion group. Conclusions:The main manifestations of PWS patients during the perinatal period are hypotonia, weak crying, feeding difficulties, decreased fetal movement, cryptorchidism and those patients are more likely to be born by cesarean section. In newborns with these characteristics, pediatricians should be aware of the possibility of PWS. In terms of the relationship between genotypes and phenotypes, polyhydramnios is more frequently observed in the non-deletion group.

Objective:To evaluate the effect of esketamine combined with ultrasound-guided dorsal penile nerve block (DPNB) on negative postoperative behavioral changes (NPOBCs) in pediatric patients undergoing circumcision under general anesthesia.Methods:One-hundred and ninety-five pediatric patients, aged 4-8 yr, with body mass index of 10-35 kg, of American Society of Anesthesiologists Physical Status classificationⅠ or Ⅱ, undergoing elective circumcision under general anesthesia, were selected and divided into 3 groups ( n=65 each) using a random number table method: esketamine group (group E), DPNB group (group D) and esketamine combined with DPNB group (group ED). Propofol 1.5 mg/kg was intravenously injected, and the patients were admitted to the operating room after consciousness disappeared in the 3 groups. Esketamine 0.5 mg/kg was intravenously injected in E and ED groups, and the equal volume of normal saline was given in group D. D and ED groups underwent bilateral DPNB with 0.25 % ropivacaine 0.15 ml/kg under ultrasound guidance, with the maximum total amount of the drug not exceeding 10 ml. Fentanyl 1.0 μg/kg and propofol 2.0 mg/kg were intravenously injected prior to the skin incision in the three groups. If intraoperative body movement occurred, propofol 10 mg was added, which could be repeated. The occurrence of intraoperative body movement, respiratory depression and amount of propofol added was recorded. When postoperative pain (FLACC score >4) occurred, flurbiprofen 1 mg/kg was intravenously injected for analgesia, and the usage of flurbiprofen was recorded. When emergence agitation(PEAD score>10) occurred, propofol 1 mg/kg was intravenously injected for sedation, and the occurrence of emergence agitation was recorded. Parents were followed up by telephone at 1, 7 and 30 days postoperatively to assess the occurrence of NPOBCs using the PHBQ scale. Results:Fifty-six patients in group E and 59 patients in D and ED groups finally completed the study.Compared with group E, the incidence of intraoperative body movement was significantly decreased, the amount of additional propofol was reduced, the emergence agitation score, incidence of emergence agitation and severe agitation and usage rate of postoperative flurbiprofen were decreased, and the incidence of separation anxiety at 7 and 30 days postoperatively was decreased in D and ED groups, and the incidence of intraoperative respiratory depression was significantly decreased, and the incidence of NPOBCs at 7 and 30 days postoperatively was decreased in group ED ( P<0.05). Compared with group D, the incidence of intraoperative respiratory depression was significantly decreased, the amount of additional propofol was decreased, the usage rate of postoperative flurbiprofen and incidence of sleep anxiety at 1 day postoperatively were decreased ( P<0.05), and no significant change was found in the incidence of NPOBCs at each time point after operation in group ED ( P>0.05). Conclusions:Esketamine combined with ultrasound-guided DPNB can reduce the occurrence of NPOBCs in pediatric patients undergoing circumcision under general anesthesia.
