In order to explore the pathogenic characters,diagnosis and treatment of canine leptospirosis,a retrospective analysis of the pathogenetic factor,diagnosis and treatment of three dogs were reported which diagnosed as canine leptospirosis in China Agricultural University Teaching Animal Hospital from August to November,2015.The infected dogs showed symptoms of depressed,jaundice,anorexia and vomiting.Two of them had fever history and contacted the water resource outside before getting ill.All three dogs were confirmed anemia,liver and kidney damage by laboratory examination.They were diagnosed with canine leptospirosis according to the positive results of the Leptospira PCR examination base on urine.During the diagnosis and treatment process,one of them was dead,the rest two recovered after antibiotic and symptomatic therapy.In conclusion,dogs which infected with leptospirosis may have a contact with the infected water before.The Leptospira PCR examination base on urine can be used for the diagnosis method of the disease.As to treatment,the use of penicillin and tetracycline drugs such as doxycycline is recommended.

Objective: To understand prevention and control of infectious disease among primary schools in Xi’an. Methods: A total of 93 primary schools were selected through multi-stage stratified sampling method from 14 counties in Xi’an, then these schools are surveyed to meaure the classroom ventilation. Results: About 28.0% (26/93) of these schools met the national standard for health staffs, with 7.4%(4/54) in urban primary schools and 56.4% in rural primary schools (22/39), the difference between urban and rural areas is statistically significant(P<0.01). Urban primary schools were better than rural primary schools in morning inspection, registration and tracking for illness, verification of vaccination certificates, surveillance and reporting of epidemic outbreaks, verification of school recovery(P<0.05). The average per capita area among the 92 primary schools was (1.22±0.34) m2, with (1.08±0.26) m2 in urban primary schools and (1.42±0.33) m2 in rural primary schools, the difference between urban and rural areas was statistically significant (P<0.01). The average per capita ventilation area of 92 primary schools was (0.15±0.07) m2 with (0.13±0.04) m2 in urban primary schools and (0.19±0.08) m2 in rural primary schools, the difference between urban and rural areas was statistically significant (P<0.01). Conclusion School-based infectious diseases prevention and control needs to be improved in Xi’an, especially in health personnel. Urban schools appear superior in the prevention and control of infectious diseases and sanitary conditions, while rural schools appear superior in student density and classroom ventilation.

Objective: To evaluate the efficacy and safety of Shexiang Tongxin dropping pill (ShXT) in the treatment ofslow blood flow after PCI (Percutaneous Transluminal Coronary Intervention), and to provide evidence for clinicaltreatment of patients with slow blood flow after PCI or to provide evidence for further research and design. Methods: "Shexiang Tongxin", "PCI", "percutaneous coronary intervention", "shexiangtongxin", "shexiang tongxin", "percutaneouscoronary intervention" were used as key words. Randomized controlled clinical trial (RCT), system evaluation, retrospective case analysis and case-control trials of randomized controlled clinical trials were searched in the databasesof Pubmed, Cochrane, web of science, CNKI, WIP, CBM, and other databases. Cochrane risk assessment tool and NOSrating scale were used to evaluate the quality of literature, and the classification of literature evidence was evaluatedaccording to Oxford criteria of evidence classification and recommended opinion strength in 2001. Results: A total of 3 articles of RCT related to the subject were selected, including 1 case control trial, including 335 patients. The resultsshowed that: (1) The frequency of thrombolysis, heart ejection fraction and TIMI blood flow in patients with slow coronaryartery flow after treatment with Shexiang Tongxin dropping pills were significantly higher than those before treatment. (P ＜ 0.05) . (2) After treatment with Shexiang Tongxin dropping pills, the effective rate of clinical symptoms was 97.8％, which was higher than that of the treatment group 11.1％. (3) There were no adverse reactions in the ShXT group duringthe treatment period. Conclusion: The efficacy and safety of Shexiang Tongxin dropping pills for patients with slow bloodflow after PCI were good. However, the dosage, method, period and outcome of the clinical study of slow blood flow afterPCI were not uniform because of the dosage, method, period of taking Shexiang Tongxin dropping pills in patients afterPCI. It is suggested that the clinical study should be aimed at the choice of different dosages before and after theadministration of drugs. The multicenter prospective randomized controlled trial can provide more evidence for itsclinical application.

Objective To explore the safety and cosmetic effect of nipple-sparing modified radical mas tectomy and immediate tissue expander implantation with single circumaereolar incision.Methods 30 patients were enrolled in Peking Union Medical College Hospital between Jan.2014 and Dec.2015.All the patients were categorized according to surgical incision (single circumaereolar incision group vs double incisions group).Data on clinicopathological parameters,average hospital stay,complications and overall cosmetic effect were retrospectively collected.Data was performed with Chi-square test,Fisher exact test and t-test.Statistical significance was defined as P＜0.05.Results 19 patients were enrolled in single circumaereolar incision group,and 11 patients in double incisions group.There was no significant difference for operation duration (P=0.093) and average hospital stay (P=0.339).After follow-up for 19.1 months,ranging from 8 to 31 months,no patients developed seroma or arm lymphedema.There was no statistical significance between the two groups in terms of sensation in nippleaereolar area (P=0.973),bilateral symmetry (P=0.650) and overall cosmesis (P=0.483).Conclusion single circumaereolar incision nipple-sparing modified radical mastectomy and immediate tissue expander implantation can be one of the preferable surgical procedures with benefits of minimal invasiveness,reliable oncological safety and decent cosmetic effect.

Objective To explore a method to generate regulatory dendritic cells (DCregs) from murine bone marrow induced by 5-Aminolevulinic acid combined with ferrous iron (ALA/SFC).Methods Bone marrow cells were obtained from male C57BL/6 mice.To generate conventional DCs (BM-DCcons),the ceils were cultured in RPMI-1640 medium supplemented with 10％ FCS,10 ng/mL GM-CSF,10 ng/mL IL-4 for 7 days.The cells were collected for the analysis.To generate DCregs by ALA/SFC,the cells were cultured in RPMI-1640 medium supplemented with 10％ FCS,20 ng/mL GM-CSF,5-ALA 1 mmol/L + SFC 0.5 mmol/L for 7 days.The morphology of ALA-DCregs was observed by microscope and eytospin with May-Grunwal&Giemsa stain.The surface markers of ALA-DCregs were observed by FACS.The function of ALA-DCregs was detected by in vitro mixed lymphocyte reaction (MLR) and in vivo lymphocyte proliferation assay.Results The generated ALA-DCregs displayed an irregular shape with areas of protrusion and demonstrated higher CD11b/CD11c and higher MHC-II but lower CD40,CD80,CD86 expression levels than DCcons.They also had immune regulation effects in both in vitro and in vivo lymphocyte proliferation assay.Conclusion This study illustrated a feasible approach for generating functional DCregs from murine bone marrow induced by ALA/SFC.These cells can be useful for research and application of DC immunotherapy in the future.

Objective: To explore the association between the 21-gene recurrence score (RS) and clinicopathologic characteristics as well as prognosis in patients with axillary lymph node negative, hormone receptor (HR) positive breast cancer. Methods: The clinicopathologic data of 439 early breast cancer patients who underwent 21 gene RS testing was retrospectively analyzed. According to the 21 gene RS, the patients were divided into low risk (295 cases), intermediate risk (111 cases) and high-risk (33 cases) group. The relationship between the 21 gene RS and clinicopathological characteristics, treatment, recurrence and metastasis was analyzed. Univariate and multivariate statistical analyses were used to analyze the risk factors for relapse free survival (RFS). Results: Tumor grade, estrogen receptor (ER), progesterone receptor (PR) and Ki-67 index were significantly different among the 3 risk cohorts (P<0.001 for all). After a median follow-up of 32 months, the recurrence rate in low risk group (3.7%) was significantly lower than that in the intermediate-high risk group (9.0%), the locoregional recurrence (LRR) rate of low, intermediate and high risk group was 2.4%, 6.3% and 9.1%; and the distant metastasis (DM) rate in low risk group was 1.4% and 2.1% in the intermediate-high risk group. Univariate analysis showed RS, ER status and endocrine therapy were prognostic factors for RFS (P<0.05 for all). Multivariate analysis showed that RS was an independent significant predictor for RFS (P=0.04). Conclusions The 21-gene RS is related to tumor grade, ER, PR and Ki-67 index. RS is an independent risk factor for RFS in patients with hormone receptor positive early-stage breast cancer.

OBJECTIVE: To obtain skin-derived induced pluripotent stem cells (iPSCs) from an Osteogenesis imperfecta (OI) patient carrying WNT1^c.677C>T mutation in order to provide a new cell model for investigating the underlying molecular mechanism and stem cell therapy for OI. METHODS: The pathogenic variant of the patient was identified by Sanger sequencing. With informed consent from the patient, skin tissue was biopsied, and primary skin fibroblasts were cultured. Skin fibroblasts were induced into iPSCs using Sendai virus-mediated non-genomic integration reprogramming method. The iPSC cell lines were characterized for pluripotency, differentiation capacity, and karyotyping assay. RESULTS: The patient was found to carry homozygous missense c.677C>T (p.Ser226Leu) mutation of the WNT1 gene. The established iPSC lines possessed self-renewal and capacity for in vitro differentiation. It also has a diploid karyotype (46,XX). CONCLUSION A patient-specific WNT1 gene mutation (WNT1^c.677C>T) iPSC line was established, which can provide a cell model for the study of OI caused by the mutation.

Objective:To investigate the effects of probiotics on intestinal flora, intestinal function, and T lymphocyte level in patients with cervical cancer after radiotherapy.Methods:A total of 92 patients with cervical cancer who underwent pelvic radiotherapy in The Second Affiliated Hospital of Zhengzhou University from September 2020 to February 2022 were included in this study. They were randomly divided into control and experimental groups ( n = 46/group). The patients in the experimental group took probiotics during radiotherapy, while the patients in the control group did not take probiotics during radiotherapy. The amount of intestinal flora, D-lactic acid, diamine oxidase, and T lymphocyte subset levels pre- and post-radiotherapy were compared between the two groups. Urinary lactulose (L) and mannitol (M) concentrations were determined in each group. Urinary excretion ratios of L to M were calculated. Results:After 10, 15, and 20 times of radiotherapy and after all radiotherapies, the amount of Escherichia coli and Enterococcus in the experimental group was significantly lower than that in the control group ( F = 128.60, 224.99, all P < 0.05). The amount of Bifidobacteria and Lactobacilli in the experimental group was significantly higher than that in the control group ( F = 2 065.46, 948.23, both P < 0.05). After 10, 15, and 20 times of radiotherapy and after all radiotherapies, plasma D-lactic acid level in the experimental group was (9.34 ± 1.63) μg/L, (9.15 ± 1.36) μg/L, (8.68 ± 1.06) μg/L, and (8.05 ± 0.82) μg/L, respectively. After 10, 15, and 20 times of radiotherapy and after all radiotherapies, plasma diamine oxidase level in the experimental group was (86.34 ± 20.25) μg/L, (84.28 ± 17.45) μg/L, (80.40 ± 13.35) μg/L, and (76.85 ± 10.87) μg/L, respectively, and urinary excretion ratio of L to M in the experimental group was (1.84 ± 0.16), (1.55 ± 0.12), (1.26 ± 0.09), (0.98 ± 0.06), respectively, all of which were significantly lower than those in the control group ( F = 121.60, 31.73, 417.84, all P < 0.05). After 10, 15, and 20 times of radiotherapy and after all radiotherapies, CD4 + level in the experimental group was (39.80 ± 4.90)%, (40.92 ± 5.30)%, (42.52 ± 6.14)%, (43.83 ± 6.55)%, respectively, CD4 +/CD8 + was (1.52 ± 0.25), (1.63 ± 0.22), (1.71 ± 0.39), (1.83 ± 0.22), respectively, all of which were significantly higher than those in the control group ( F = 58.69, 31.07, all P < 0.05). Conclusion:Probiotics can improve the status of intestinal flora and intestinal barrier function in patients with cervical cancer after radiotherapy, and simultaneously improve the cellular immune function of patients.
