To identify Taenia cestodes from 6 regions of Yunnan province by PCR and sequencing of mtCOXⅠfragment. the genomic DNA of Taenia cestodes was extracted from proglottid collected in 6 region of Yunnan province, and mtCOXⅠ gene fragments were amplified by PCR, and then sequenced. The genomic distance and phylogenetic tree were constructed in comparison with other known mtCOXⅠgene sequences of T.solium , T.saginata and T. asiatica in GenBank using DNA MAN software. Through distance matrix,it was found that the homologie of NJ4, NJ1 and DQ2 was 99.8%, DL4 and NJ3 homologie was 99.5%, NJ2 and DQ3 homologie was 98.8%; the homologie of DL3 and BZ3 was 98.3%, while the homologie was 96.0% with BZ2; The phylogenetic tree demonstrated that 10 Taenia cestodes including NJ1-4, DL2-3and DQ1-3 occupied one brance with BZ3. BN1, CX1, LC1 and BZ2 occupied one brance, then two brance occupied and occupied with other one which was occupied by DL1 and BZ1. Taenia cestodes from Nujiang and Diqing were T. asiatica. Taenia cestodes from XiShangbanna,Lincang and Chuxiong were T.saginata.Taenia cestodes from Dali were T.solium or T.asiatica.Because same species have no difference from different regions. mtCOXⅠfragment sequencing is valid for tapeworms identification.

Objective To evaluate the effects of curcumin on the activity of NR2B and NR1 in the spinal dorsal horn in a rat model of diabetic neuropathic pain (DNP).Methods Diabetes mellitus was induced by high-sucrose and high-fat diet and intraperitoneal streptozotocin 35 mg/kg,then confirmed by fasting blood glucose level ≥ 16.7 mmol/L 3 days later in male Sprague-Dawley rats.DNP was confirmed by the mechanical paw withdrawal threshold (MWT) and thermal paw withdrawal latency (TWL) measured on day 14 after streptozotocin administration ＜ 80％ of the baseline value.The rats were then randomly divided into 3 groups (n =27 each) using a random number table:DNP,DNP+ curcumin group (group DCur)and DNP + solvent control group (group DSC).Curcumin 100 mg· kg-1 · d-1 and corn oil 4 ml· kg-1 · d-1 were injected intraperitoneally for 14 consecutive days starting from 14 days after administration of streptozotocin in DCur and DSC groups,respectively.Another 27 normal male Sprague-Dawley rats served as control group (group C) and were fed with normal forage.At 3,7 and 14 days after curcumin injection,MWT and TWL were measured and the lumbar segments (L4-6) of the spinal cord were removed.The expression of pTyr1472-NR2B and pSer896-NR1 in the spinal dorsal horn was determined by immunohistochemistry and Western blot.Results Compared with group C,MWT was significantly decreased,TWL was shortened,and the expression of pTyr1472-NR2B was up-regulated at each time point in group DNP.Compared with group DNP,MWT was significantly increased,and TWL was prolonged at 7 days after curcumin injection,and the expression of pTyr1472-NR2B was down-regulated at 3 days after curcumin injection in group DCur.There was no significant difference in each parameter between DNP and DSC groups,and in the expression of pSer896-NR1 between the four groups.Conclusion The mechanism by which curcumin mitigates neuropathic pain in type 2 diabetic rats may be related to inhibition of up-regulation of pTyr1472-NR2B expression,while unrelated to pSer896-NR1 expression in the spinal dorsal horn.

Objective To explore the prognosis of endoscopic tissue adhesives injection in treating liver cirrhosis patients with esophageal gastric varices (GOV),and to evaluate the effects of various factors on bleeding after treatment.Methods A total of 157 liver cirrhosis patients with GOV treated by endoscopic tissue adhesives injection with or without ligation therapy were retrospectively analyzed.The basic information,liver function and blood biochemical values of patients at enrollment were investigated.The analysis of bleeding after treatment was conducted by Kaplan-Meier.The survival curves comparison was conducted by Log-rank test.Logistic regression model was used for multivariate analysis.The prognosis predictors were evaluated by receiver operating characteristics (ROC) curves and the area under the curve (AUC).Results Rebleeding happened in 26 of 157 patients.The median rebleeding time was 3.4 months.The results of univariate analysis indicated that there were statistical differences in FIB4 scores (Z=-1.282,P=0.100) and the inner diameter of the right portal vein (Z=-1.812,P=0.035) between bleeding group and no bleeding group.The results of multivariate analysis showed that the inner diameter of the right portal vein was independent prognostic factor of rebleeding (OR =1.733,95％ CI:1.045 to 2.874,P =0.033).Optimal diagnostic threshold was 8.5 mm (AUC=0.724,95 ％CI:0.537 to 0.910),sensitivity and specificity was 77.8％ and 66.6％ respectively.Conclusions The inner diameter of the right portal vein was one of the important factors that affected the efficacy of tissue adhesives injection in preventing bleeding and the prognosis.FIB4 score had certain reference value in predicting recurrence or bleeding after treatment.

Objective:To evaluate the influencing factors of carotid-femoral pulse wave velocity (CF-PWV) and its value to predict outcomes in peritoneal dialysis (PD) patients.Methods:Eligible patients undergoing PD in Renji Hospital of Shanghai Jiao Tong University between August 2016 and July 2018 were recruited and prospectively followed up until death, PD cessation, or to the end of the study. CF-PWV was measured by an arterial pulse wave velocity meter to assess arterial stiffness (July 31, 2020). Overhydration was measured by bioimpedance spectroscopy. The patients were divided into CF-PWV≤10 m/s group and CF-PWV>10 m/s group according to the measured value of CF-PWV. The influencing factors of elevated CF-PWV were analyzed by multivariate logistic regression. Survival curves were generated using the Kaplan-Meier method and multivariate Cox proportional hazards models were used to analyze the difference for all-cause mortality and cardiovascular disease (CVD) mortality between the two groups.Results:A total of 224 PD patients were enrolled, including 133 males (59.4%). The age was (55.2±13.4) years old, and median PD vintage was 22.3(6.5, 59.3) months. Among them, 47(21.0%) patients were comorbid with diabetes, and 37(16.5%) patients had CVD history. The median CF-PWV was 9.6(8.4, 11.4) m/s for the cohort, and 105(46.9%) participants had CF-PWV over 10 m/s. Compared with CF-PWV≤10 m/s group, CF-PWV>10 m/s group patients had older age, increased percentage of diabetes and CVD (all P<0.05). Multivariate logistic analysis showed that increased age ( OR=1.070, 95% CI 1.043-1.099, P<0.001), diabetes ( OR=3.693, 95% CI 1.646-8.287, P=0.002) and higher overhydration ( OR=1.238, 95% CI 1.034-1.483, P=0.020) were independent influencing factors for elevated CF-PWV in PD patients. After followed up for 37.4(25.6, 41.7) months, 24 patients died, including 19 cases of CVD-related deaths. Kaplan-Meier survival analysis showed that all-cause mortality and CVD mortality were significantly higher in the CF-PWV>10 m/s group than those in CF-PWV≤10 m/s group (Log-rank χ2=6.423, P=0.011; Log-rank χ2=6.243, P=0.012, respectively). Multivariate Cox proportional hazards models showed that increased age was an independent influencing factor for both all-cause mortality and CVD mortality ( HR=1.057, 95% CI 1.010-1.107, P=0.018; HR=1.062, 95% CI 1.009-1.118, P=0.022). Conclusions:Increased arterial stiffness is relatively common in PD patients. Higher CF-PWV in PD patients is associated with increased age, diabetes and higher overhydration, and it is probably a valuable predictor of outcome in PD patients.

Objective To analyze the risk factors associated with acute type A aortic dissection,and to establish an effective predictive scoring model for early clinical intervention.Methods A retrospective review of 200 patients diagnosed as acute type A aortic dissection in the Department of Emergency,Guangdong Provincial People's Hospital between April 1,2012 and March 31,2017 was conducted as a modeling group.There were 160 males and 40 females with age of (53.30 ±13.19) years.According to the criteria of dissection rupture within 72 h after CTA examination,patients were divided into a rupture group (100 cases) and an unruptured group (100 cases).A prediction model of rupture risk was established based on the multivariate Logistic regression analysis of the risk factors of acute A-type aortic dissection in the early stage.After the establishment of the model,a prospective review of 80 patients diagnosed as acute type A aortic dissection in our hospital between April 1,2017 and May 31,2018 was conducted as a validation group.There were 57 males and 23 females with age of (54.00 ±13.68) years.In the validation group,there were 53 patients with rupture and 27 patients without rupture.Furthermore,this model was verified in the validation group.The scores were divided into low-risk rupture and high-risk rupture according to the best cut-off value of the receiver operating model curve of the modeling group.Results Logistic regression analysis showed that 10 factors were finally established the rupture risk prediction score model.The factors were as following:age ＞63 years (2 points),women (2 points),ventilator assisted ventilation (3 points),AST ＞80 U/L (2 points),no distortion of the inner membrane (2 points),diameter of the aortic sinus ＞41 mm (1 point),maximum diameter of the ascending aorta ＞48 mm (1 point),ratio of false lumen area to true lumen area ＞2.12 (2 points),Lac ＞1.9 mmol/ L (3 points),and WBC ＞14.2×109/L (1 point).The results of validation showed that the scoring model had a high predictive value (AUC =0.928,95％ CI:0.872-0.984,P ＜ 0.001) and goodness of fit (Hosmer-Lemeshow x2 =8.331,P =0.402).Moreover,the scoring model was further divided into low-risk (0-6 points) and high-risk (7-19 points),with sensitivity of 83.0％ and specificity of 86.0％.Conclusions The predictive model of dissection risk in the acute type A aortic dissection constructed within 72 h after CTA is helpful for the evaluation of the disease and early intervention,and has certain clinical application value.

Objective To investigate the effect of acupoint catgut embedding combined with Ziwu-Liuzhu theory based acupuncture on the clinical efficacy and sleep quality of depressive patients. Methods A total of 64 patients who met the inclusion criteria were randomly divided into two groups, 32 in each group. The control group was treated with routine electro-acupuncture, while the observation group was treated with acupoint catgut embedding combined with Ziwu-Liuzhu theory based acupuncture. Both groups were treated for 8 weeks. Sleep quality was assessed by Pittsburgh Sleep Quality Index (PSQI), and depression was assessed by Hamilton Depression Scale (HAMD) to evaluate the clinical efficacy. Results After treatment, the HAMD score (11.3 ± 2.4 vs. 14.5 ± 2.6, t=4.986) and PSQI index (9.6 ± 2.3 vs. 11.8 ± 2.5, t=3.307) in the observation group were significantly lower than those in the control group (P<0.01). The quality of life (12.9 ± 2.3 vs. 11.3 ± 2.5, t=2.598) and mental health score (13.5 ± 2.4 vs. 11.3 ± 2.6, t=3.413) of WHOQOL-BREF scale in the observation group were significantly higher than those in the control group (P<0.01). The total effective rate was 93.8％ (30/32) in the observation group and 75.0％ (24/32) in the control group. There were significant differences between the two groups (χ2=4.246, P=0.038). Conclusions Acupoint catgut embedding combined with Ziwu-Liuzhu theory based acupuncture can effectively improve depressive state, sleep quality and quality of life in patients with depression, and the curative effect is better than conventional electro- acupuncture treatment.

Objective:To evaluate the differential expression of blood routine in different types of infection and the diagnostic value of C-reactive protein (CRP), procalcitonin (PT), ferritin (SF) and lactate dehydrogenase (LDH) in bacterial and mycoplasma pneumonia and their early warning value in severe cases.Method:A total of 627 patients, including 176 cases of bacterial pneumonia, 275 cases of mycoplasma pneumonia, 176 cases of viral infection and 180 cases of normal control were collected from May 2018 to December 2019 in children′s Hospital Affiliated to Capital Institute of Pediatrics. The mycoplasma pneumonia group was divided into mild group (151 cases) and severe group (124 cases) according to the results of lavage fluid RNA-examination. All patients received completed blood routine test at the first day of admission, patients in bacteria group and Mycoplasma group received the examination of four inflammatory indicators. The Kruskal-Wallis test was used to analyze the differences in blood routine results between different infection groups, and the differences of inflammatory indexes between bacterial group and Mycoplasma mild and severe group. The receiver operating characteristic (ROC)-curve method was used to analyze the predictive value of inflammatory indexes between different infection groups.Results:There were significant differences in leukocyte count, neutrophil, lymphocyte and monocyte percentage between bacterial pneumonia, mycoplasma pneumonia, viral infection and normal control group ( P<0.05). The differences of four inflammatory indexes in bacterial group, mild Mycoplasma group and severe group were statistically significant ( P<0.05). The rest of the index (CRP, PCT, LDH, SF and white blood cell count) were P<0.05 (CRP: area under curve [AUC] 0.799; PCT: AUC 0.579; LDH: AUC 0.651; SF: AUC 0.854), in mild and severe mycoplasma group, except WBC, by ROC-curves analysis. The AUC value of the area under the curve of CRP and SF is high, and the sensitivity and specificity at the diagnostic critical point are high, which has great diagnostic value (CRP: diagnostic critical point 12.55 mg/L, sensitivity 0.719, specificity 0.755; SF: diagnostic critical point 176.02 μg/L, sensitivity 0.765, specificity 0.960). ROC curve results also showed that of PCT, White blood cell and neutrophil percentage had the diagnostic value in bacterial infection and mycoplasma infection, P<0.05 (PCT: AUC 0.658; leukocyte: AUC 0.804; neutrophil: AUC 0.630). Leukocyte count is the best differential index (diagnostic critical point 9.585×10 9/L, sensitivity 0.778, specificity 0.698), PCT has higher sensitivity at the diagnostic critical point of 0.55 μg/L, but the specificity is slightly lower (diagnostic critical point of 0.55 μg/L, sensitivity 0.862, specificity 0.366). Conclusions:PCT and leukocyte count can be used as the preferred inflammatory indexes to distinguish bacterial and mycoplasma infection. CRP, LDH, PCT and SF can be used as early warning indexes to evaluate severe mycoplasma infection.

Objectives:To investigate the genetic characteristics of the blaNDM-1-carrying plasmid of the multidrug resistant Enterobacter hormaechei subsp. hoffmannii clinical isolate C37, and constructing a phylogenetic tree of the 66 publicly available genomes of the Enterobacter hormaechei subsp. hoffmannii to explore its global epidemic situation. Methods:Carbapenem-resistant Enterobacter cloacae complex (CRECC) strains isolated from the First Affiliated Hospital of Sun Yat-sen University from August 2014 to August 2021 were collected. Matrix-assisted laser desorption/ionization-time of flight mass spectrometry (MALDI-TOF MS) and 16S rDNA Sanger sequencing were used for species identification. Micro broth dilution method was used for antibacterial susceptibility test. The polymerase chain reaction (PCR) was used to detect the β-lactamase resistance gene and plasmid-mediated quinolone resistance (PMQR) gene carried by the C37 strain. The conjugation experiment was used to confirm the conjugative metastasis of the resistance genes in C37 strain. Whole genome of the C37 strain was sequenced. Core genome was extracted and the phylogenetic analysis of 66 publicly available Enterobacter hormaechei subsp. hoffmannii was performed. Results:Enterobacter hormaechei subsp. hoffmannii C37 strain is resistant to third-generation cephalosporins, carbapenems, aminoglycosides and quinolones, and carries blaACT-5, blaNDM-1, qnrA1, aac(6′)-Ib-cr, oqxAB, fosA, dfrA15 and other resistance genes, as well as IncX3, IncX4, IncFIB and IncFII plasmids. Multilocus sequence typing (MLST) analysis showed that C37 strain belongs to the ST78 type of Enterobacter cloacae complex (ECC). Conclusions:ST78 type Enterobacter hormaechei subsp. hoffmannii is closely related to the spread of carbapenem resistance genes. It is a potential high-risk clone to spread carbapenem resistance genes. The prevalence and trends of ST78 type Enterobacter hormaechei subsp. Hoffmannii should be monitored.

Objective:To investigate the longitudinal trajectory and influencing factors of cancer-related fatigue (CRF) in breast cancer patients during chemotherapy.Methods:From March 2019 to January 2020, breast cancer patients in Longhua Hospital Affiliated to Shanghai University of Traditional Chinese Medicine, Yueyang Hospital of Integrated Traditional Chinese and Western Medicine Affiliated to Shanghai University of Traditional Chinese Medicine and Peking Union Medical College Hospital were selected as the research objects to conduct follow-up investigation. The survey tools included general information questionnaire, Cancer-related Fatigue Assessment Scale, International Physical Activity Questionnaire, and the Pittsburgh Sleep Quality Index Scale.Results:A total of 91 patients were included in the study. The incidence of severe CRF at each time point before chemotherapy, 3 weeks after chemotherapy and 6 weeks after chemotherapy were 1.1% (1/91), 8.8% (5/57) and 2.1% (1/48), respectively. The results of the generalized estimation equation showed that the trajectory of the total score CRF firstly increased and then decreased, reaching a peak at 3 weeks after chemotherapy (35.45±13.07), and mild CRF change showed statistical difference ( P<0.05). In addition, BMI and sleep and daytime dysfunction were the influencing factors of the total score of CRF. Disease stage, sleep disturbance and daytime dysfunction were the influencing factors of CRF with different severity. Conclusions:CRF is a prominent problem in breast cancer patients during chemotherapy. Attention should be paid to high-risk individuals with abnormal BMI and daytime function by medical staff.
