Objective: To investigate the drug resistance pattern and drug resistance genotypes of Salmonella. spp isolated from fecal specimens and anal swabs of diarrhea cases in Anhui Province. Methods: The 149 strains of Salmonella.spp isolated from feces and anal swabs of diarrhea cases in Anhui Province from April to October 2017 were selected. The serotypes of Salmonella.spp were identified by slide agglutination. The susceptibility of all strains to 14 antibiotics were determined by micro-broth dilution method. Sixty of the cephalosporin-resistant antibiotics were selected. The β-lactamase encoding genes bla_TEM, bla_SHV, bla_OXA-1, bla_OXA-2, bla_PER, bla_CMY, bla_CTX-M, and colistin resistance genes mcr-1 and mcr-2 were performed using the multi-PCR method. Results: Of the 149 diarrhea cases, the median (P₂₅, P₇₅) of the age was 5.0 (1.1, 38.5). The 92 of them were male and 54.4% were children. Of the 149 strains of Salmonella.spp, 105 strains had different degrees of resistance to 13 antibiotics other than imipenem. The resistance rate of ampicillin was 55.0% (82/149), which was the highest. 53.0% strains (79 strains) were multidrug resistant, main of which were Salmonella typhimurium and Salmonella enteritidis. A total of 53 resistance patterns were detected, and 10 strains were resistant to ampicillin-ampicillin/sulbactam-tetracycline-chloramphenicol-cefazolin-trimethoprim/sulfamethoxazole, which was the most common resistance pattern. Among the 60 cephalosporin resistant strains, 45 strains carried bla_TEM-1, 6 of which also carried bla_CTX-M-14 and 3 of which also carried bla_CTX-M-65. All the 32 strains carried only bla_TEM-1 show resistance to ampicillin and 31 of them show resistance to cefazolin. There were 2 strains showing negative results of gene detection. mcr-1 was detected in a multidrug resistant strain. Conclusion The resistance of Salmonella.spp to ampicillin shows a serious situation in this region, and there were a number of multidrug resistant strains. The bla_TEM-1 was the major drug resistance gene detected in this research. Detection of the mcr-1 suggests the emergence of surveillance to colistin resistance of Salmonella.spp in this area.

Fourteen neonatal diabetes mellitus(NDM)patients were recruited. 9 patients were treated with glyburide and the other 5 with insulin. ABCC8, KCNJ11, and INS genes were sequenced in 6 of them. Gene mutations were found in 2, 1, and 1 cases in these genes, respectively. One case with 6q24 hypomethylation and another without known mutation were also found. 8 out of 9 patients treated with glyburide reached euglycemia(88.9%). The other 5 patients with insulin therapy either died or lost contact. The results suggest that glyburide therapy is effective in neonatal diabetes mellitus, while insulin therapy may contribute to poor compliance.

In this study, the current status for breast diseases in a region with high-incidence of cervical cancer were epidemiologically investigated. From March to August, 2009, 17618 women, from Wufeng area of Hubei province, China, were recruited to screen breast diseases by using breast infrared diagnostic apparatus. Other diagnostic methods, such as B-mode ultrasound, X-ray mammography, needle biopsy and pathological examination were, if necessary, used to further confirm the diagnosis. The screening showed that 5990 of 17618 cases (34.00%) had breast diseases, 5843 (33.16%) had mammary gland hyperplasia, 48 (0.27%) had breast fibroadenoma, 11 (0.06%) had breast carcinoma, and 88 (0.50%) had other breast diseases. The peak morbidity of breast cancer was found in the women aged 50-60 ages. The morbidity of breast cancer was significantly increased in women elder than or equal to 50 years old (n=8, 0.157%) in comparison with that in the subjects younger than 50 years old (n=3, 0.024%) (u=2.327, P<0.05). It was shown that the occurrence of breast diseases was concentrated in women aged 20-40 years, while the total morbidity reached its peak at the age of 30 years and then decreased sharply after age of 40. Compared with the patients elder than or equal to 40 years old (n=3289, 27.46%), the morbidity rate of breast diseases was significantly increased in women less than 40 years old (2648 cases, 47.18%; P<0.001). However, there was no significant difference in the morbidity of breast diseases between the age group of 20-29 years and that of 30-39 years (P=0.453), and both of them were high. There was no significant association between the morbidity of breast diseases and cervical cancer. Since the morbidity of breast diseases was higher among young women, more attention should be paid to the screening of breast diseases among young women for early diagnosis.

Objective:To investigate COVID-19 vaccination status and relevant adverse reactions in patients with psoriasis treated with biological agents, and to explore the effect of COVID-19 vaccination on psoriatic lesions.Methods:Clinical data were collected from 572 psoriasis patients aged 18 - 60 years, who were registered in the management system of psoriasis patients treated with biological agents in the University of Hong Kong-Shenzhen Hospital from May 2019 to June 2021. The COVID-19 vaccination status was investigated by telephone interviews, and the vaccination-related information was obtained by fixed healthcare workers during a fixed time period according to a predesigned questionnaire. Measurement data were compared between two groups by using t test, and enumeration data were compared by using chi-square test or Fisher′s exact test. Results:The COVID-19 vaccination coverage rate was 43.13% (226 cases) among the 524 patients who completed the telephone interview, and was significantly lower in the biological agent treatment group (30.79%, 105/341) than in the traditional drug treatment group (66.12%, 121/183; χ2 = 60.60, P < 0.001) . The main reason for not being vaccinated was patients′ fear of vaccine safety (49.66%, 148/298) , followed by doctors′ not recommending (26.51%, 79/298) . In the biological agent treatment group after vaccination, the exacerbation of psoriatic lesions was more common in patients receiving prolonged-interval treatment (42.86%, 6/14) compared with those receiving regular treatment (4.40%, 4/91; Fisher′s exact test, P < 0.001) . Skin lesions were severely aggravated in two patients after COVID-19 vaccination, who ever experienced allergic reactions and whose skin lesions did not completely subside after the treatment with biological agents. Conclusions:The COVID-19 vaccination coverage rate was relatively low in the psoriasis patients treated with biological agents, and no serious adverse reaction was observed after vaccination. Prolonged-interval treatment due to COVID-19 vaccination ran the risk of exacerbation of skin lesions.

The saphenous vein has been one of the most commonly used vascular materials for coronary artery bypass grafting(CABG), but the low long-term patency of the vein grafts limits the surgical benefits of CABG. The traditional method of saphenous vein harvesting is more damaging to the venous structures, which has led to the development of no-touch saphenous vein harvesting techniques. In this paper, we review the clinical progress of no-touch saphenous vein in CABG and the potential mechanisms of this technique, to improve the patency of vein grafts by analyzing the latest literature and research progress at the domestic and international level.

Chronic heart failure （CHF）， the end stage of heart disease due to a variety of causes， features high disability rate and mortality， which has become a hot spot in cardiovascular field. As recorded in Treatise on Cold Damage（《伤寒论》）， Zhenwutang is composed of Radix Aconiti Lateralis Preparata， Poria Cocos， Rhizoma Atractylodis Macrocephalae， Paeoniae Radix Alba， and Rhizoma Zingiberis Recens. With the functions of warming Yang and excreting water， it is a classical prescription for the treatment of CHF in clinical settings. By searching China National Knowledge Infrastructure （CNKI）， PubMed， Wanfang Data， and VIP， we find Zhenwutang exerts therapeutic effect on CHF through multiple targets and multiple pathways. Experiments show that it alleviates CHF by antagonizing the overactivation of neuroendocrine system， inhibiting immune-inflammatory response， suppressing cardiac remodeling， restricting apoptosis， regulating autophagy， improving myocardial energy metabolism， inhibiting oxidative stress injury， protecting endothelial function， and decreasing volume load. Clinical research shows that Zhenwutang can significantly alleviate the clinical symptoms of CHF patients in a safe manner with little adverse reactions. This paper systematically summarizes the mechanisms of and clinical research on Zhenwutang in the treatment of CHF in recent years， so as to provide theoretical and experimental data for the further research and development of Zhenwutang.

Objective     To investigate the early and long-outcomes of coronary artery bypass grafting(CABG) in acute myocardial infarction (AMI) patients with coronary artery disease(CAD)(age≤45 years). Methods     Data of 596 adult CAD patients (include AMI and Angina) who underwent CABG in our hospital were collected retrospectively from May 2010 to October 2018. In an AMI group, 234 were male patients with an average age of 41.59±3.79 years; 26 were female patients with an average age of 41.64±3.03 years. In an angina group, 280 were male patients with an average age of 42.19±2.90 years; 56 were female patients with an average age of 41.54±3.52 years. Preoperative baseline variables, perioperative mortality, major adverse cardiac and cerebrovascular events (MACCE) were compared between two group.  Results    There was no significant difference in all preoperative variables. Seven patients were died and the hospital mortality rate was 1.23% (1.54% vs. 0.89%, P=0.477). The complications including reoperation for bleeding, cerebral infarction, renal failure and atrial fibrillation arrhythmia were without significant difference between two group  (P>0.05). The intensive care unit stay duration (30.66±27.46 h vs. 23.96±15.11 h), intubation duration (22.54±22.31 h vs. 18.64±11.81 h) and hospitalization costs (97 186±33 741¥ vs. 90 081±24 537¥, P=0.003) were greater in the AMI group. The hospital mortality rate and complications rate were without significant difference between STEMI (ST segment elevated myocardial infarction) and NSTEMI (non-ST-segment elevated myocardial infarction) subgroups (P>0.05). The follow-up rate was 92.6% (546 patients) and the follow-up time was 4 (0.5 to 8.5) years. All cause-mortality rate was 3.85%(21 patients), and freedom MACCE was 72.2%. The freedom from MACCE, recurred angina and cerebral infarction were without significant difference, but AMI was associated with higher rate of PCI procedure.  Conclusion     CABG procedure in CAD patients under 45 years accompanied AMI is safety and reliable both in early and the long-term outcomes.
