Objective To investigate the antimicrobial resistance of clinical isolates in Tongling People′s Hospital during 2013. Methods A total of 2 281 nonduplicate clinical isolates were collected.Kirby-Bauer disc diffusion method was employed to study the antimicrobial susceptibility.The data were analyzed with WHONET 5.6 software according to CLSI 2012 breakpoints. Results The top 5 most frequently isolated microorganisms were E.coli (479,21.0%),K.pneumoniae (360,15.8%),A. baumannii (271,11.9%),P .aeruginosa (240,10.5%),S.aureus (171,7.5%).Gram negative and gram positive microorganisms accounted for 76.5% and 23.5%,respectively.The prevalence of methicillin-resistant strains in S.aureus (MRSA)and coagulase negative Staphylococcus (MRCNS)was 38.6% and 73.1%,respectively.The resistance rates of MR strains to beta-lactams and other antimicrobial agents were much higher than those of MS strains.No staphylococcal strain was found resistant to vancomycin or teicoplanin.E.faecalis showed relatively lower resistance to penicillin,ampicillin and nitrofurantoin.E.faecium strains were more resistant than E.faecalis to most of the antibiotics tested.Approximately 50.5% of E.coli and 44.5% of Klebsiella isolates produced extended-spectrum beta-lactamases (ESBLs).The ESBLs-respectively.And 29.8% and 23.4% of the P .aeruginosa strains were resistant to imipenem and meropenem.Nearly all (94.0%)P .aeruginosa isolates were susceptible to amikacin.Conclusions There appears a trend of increasing resistance in the clinical bacterial isolates in this hospital,especially the carbapenem-resistant Enterobacteriaceae,which is of great concern.It is mandatory to take effective antibiotic policy and infection control measures.

Abstract: Schistosomiasis, an important zoonotic parasitic disease, is one of the six major tropical diseases identified by WHO, and also one of the most important parasitic diseases for prevention and control in China. After more than 70 years of efforts, the prevention and control of schistosomiasis in China has made great achievements, and the current epidemic of schistosomiasis in China has entered an extremely low epidemic state, but the distribution base of the only intermediate host of schistosomiasis, Oncomelania hupensis, is still large. For now, the techniques used to monitor schistosomiasis have shortcomings such as time-consuming, laborious and low sensitivity, which cannot meet the current needs of China. Environmental DNA (eDNA) refers to DNA that can be extracted from environmental samples (such as soil, water or air) without isolating any target organisms, which is a complex mixture of genomic DNA and its degradation products from different organisms in the same environment. eDNA technology can reflect the community or species composition information in the ecosystem through DNA extraction and detection of environmental samples. Compared with traditional biological monitoring methods, eDNA technology has the advantages of high efficiency, high sensitivity and environmental friendliness. eDNA has been successfully used for the specific detection of Schistosoma mansoni, Schistosoma haematobium and Schistosoma japonicum. This paper reviews the current detection methods of eDNA, the application and technical limitations of eDNA technology in schistosomiasis monitoring, aiming to provide scientific reference for research in the field of schistosomiasis surveillance.

OBJECTIVETo study the therapeutic effect of treatment of acute gouty arthritis (AGA) respectively by electroacupuncture (EA) with different frequency and oral intake of Western medicine.

METHODSSeventy-two patients of AGA were randomly assigned into three groups, 24 in each group. Group A was treated with EA 100 Hz; Group B with EA 2 Hz; and Group C with Western medicine. The analgesic effect, initiating time and sustaining time of analgesia were observed and the level of serum uric acid was measured before and after treatment.

RESULTSThe initiating time of analgesia was shorter while the sustaining time of analgesia was longer in Group A and B than those in Group C (all P < 0.01). The efficacy of analgesia was higher in Group B than that in Group A, and a better effect was shown in Group B in reducing serum uric acid level than that in Group A (P < 0.01), which was near that in Group C (P > 0.05).

CONCLUSIONEA is an effective treatment for AGA, and low frequency (2 Hz) EA showed a better efficacy.

OBJECTIVE:To improve the education quality of medical school,so as to provide the excellent human resources for the field of health.METHODS:2011-2014 grades of students majoring in pharmaceutical administration,pharmacy (marketing direction) and other non-medical interdisciplinary subjects were selected from our school to complete the questionnaire which conrained the questions about satisfaction and confidence for the major.The results of investigation were analyzed statistically.RESULTS:Totally 2 668 questionnaires were sent out,and 2 435 were recycled with effective recovery of 91.27％.Half of the students majoring in pharmaceutical administration or pharmacy (marketing) etc.were switched from other majors,and 38.40％(935 number) of the students wanted to change the major.The major of clinical,nursing and anesthesiology were most preferred by the students.Only 15.52％ (378 number),26.32％ (641 number) of the students thought that the school paid enough attention to them or had a positive attitude to their major,respectively.Students majoring in pharmacy (marketing) and health services administration had the lowest satisfaction about their major and the attention paid by the school (P＜0.001).With the growth of grade,the satisfaction of students in various aspects had declined (P＜0.001).Only 44.72％ (1 089 number),34.25％ (834 number) of the students had positive attitude towards the study or were optimistic about the future,respectively.With the growth of the grade,students' satisfaction in all aspects had declined (P＜0.001).Compared to other students,freshman had more positive attitude towards the study or were more optimistic about the future (P＜0.001).Besides,33.65％ (491 number)of the students planning to work immediately after graduation lacked confidence to find a good job.CONCLUSIONS:The lower degree of satisfaction and confidence are found in the students majoring in non-medical interdisciplinary subject in the medical school,and this should be treated seriously by the school.

OBJECTIVE: To systematically summarize the clinical features of coronavirus disease 2019 (COVID-19) in children. METHODS: PubMed, Embase, Web of Science, The Cochrane Library, CNKI, Weipu Database, and Wanfang Database were searched for clinical studies on COVID-19 in children published up to May 21, 2020. Two reviewers independently screened the articles, extracted data, and assessed the risk of bias of the studies included. A descriptive analysis was then performed for the studies. Related indices between children with COVID-19 and severe acute respiratory syndromes (SARS) or Middle East respiratory syndrome (MERS) were compared. RESULTS: A total of 75 studies were included, with a total of 806 children with COVID-19. The research results showed that the age of the children ranged from 36 hours after birth to 18 years, with a male-female ratio of 1.21 : 1. Similar to SARS and MERS, COVID-19 often occurred with familial aggregation, and such cases accounted for 74.6% (601/806). The children with COVID-19, SARS, and MERS had similar clinical symptoms, mainly fever and cough. Some children had gastrointestinal symptoms. The children with asymptomatic infection accounted for 17.9% (144/806) of COVID-19 cases, 2.5% (2/81) of SARS cases, and 57.1% (12/21) of MERS cases. The children with COVID-19 and MERS mainly had bilateral lesions on chest imaging examination, with a positive rate of lesions of 63.4% (421/664) and 26.3% (5/19) respectively, which were lower than the corresponding positive rates of viral nucleic acid detection, which were 99.8% and 100% respectively. The chest radiological examination of the children with SARS mainly showed unilateral lesion, with a positive rate of imaging of 88.9% (72/81), which was higher than the corresponding positive rate of viral nucleic acid detection (29.2%). Viral nucleic acid was detected in the feces of children with COVID-19 or SARS, with positive rates of 60.2% (56/93) and 71.4% (5/7) respectively. The children with COVID-19 had a rate of severe disease of 4.6% (31/686) and a mortality rate of 0.1% (1/806), the children with SARS had a rate of severe disease of 1.5% (1/68) and a mortality rate of 0%, and those with MERS had a rate of severe disease of 14.3% (3/21) and a mortality rate of 9.5% (2/21). CONCLUSIONS Children with COVID-19 have similar symptoms to those with SARS or MERS, mainly fever and cough. Asymptomatic infection is observed in all three diseases. Children with COVID-19 or SARS have milder disease conditions than those with MERS. COVID-19 in children often occurs with familial aggregation. Epidemiological contact history, imaging examination findings, and viral nucleic acid testing results are important bases for the diagnosis of COVID-19.

ObjectiveTo investigate the possible mechanism of Bushen Zhuyun prescription （BSZYP） to reduce the level of ovarian apoptosis in Brown Norway （BN） rats with luteal phase deficiency （LPD）. MethodFifty SPF female BN rats were randomly divided into a model group， a dydrogesterone group （0.002 g·kg^-1）， and a low （4.5 g·kg^-1）， a medium （9 g·kg^-1）， and a high-dose （18 g·kg^-1） BSZYP groups， with ten rats in each group. The rats were administrated with corresponding drugs by gavage， once a day for three estrus cycle. Western blot was used to detected the protein expression levels of c-Jun NH2 terminal kinase （JNK）， extracellular signal-regulated kinase （ERK）， phosphorylated-ERK （p-ERK）， phosphorylated-JNK （p-JNK）， p38 mitogen-activated protein kinase （p38 MAPK）， phosphorylated-p38 MAPK （p-p38 MAPK ）， B-cell lymphoma （Bcl-2）， and Bcl-2 associated X protein （Bax） in ovary. Real-time quantitative polymerase chain reaction （Real-time PCR） was used to detect the mRNA expression levels of ERK， JNK， p38 MAPK， Bax， and Bcl-2 in ovary. Enzyme-linked immunosorbent assay （ELISA） was used to detect the serum progesterone （P） and estradiol （E₂） levels. Hematoxylin-eosin （HE） staining was used to observe the ovarian tissue morphology. ResultCompared with the model group， the recovery of estrus cycle of rats in all BSZYP groups had statistical significance after 1-circle administration （P<0.05）. The ovarian tissue morphology in the low-dose BSZYP group was improved， and that in the medium and high-dose BSZYP groups was significantly improved with clear follicle， less vesicular follicle and atretic follicle， and more granular layers. The number of luteum， especially the fresh luteum， in the medium and high-dose groups was increased with smooth edge and large volume. The mRNA expression level of Bcl-2 was increased in all-dose BSZYP groups， while the mRNA expression level of Bax was significantly decreased in all-dose BSZYP group （P<0.05， P<0.01）. The mRNA expression levels of JNK and p38 MAPK were significantly decreased in the high-dose BSZYP group （P<0.01）， and the mRNA expression levels of ERK were increased in the low and medium-dose BSZYP groups （P<0.05）. The protein expression level of Bcl-2 was significantly increased in the medium and high-dose BSZYP groups （P<0.01）， and the protein expression level of Bax was significantly decreased in the all-dose BSZYP groups （P<0.01）. No significant difference was observed in the protein expressions of JNK， ERK， and p38 MAPK in the BSZYP groups. The protein expression levels of p-ERK in the ovarian tissues of rats were significantly inoreased in the medium and high-dose BSZYP group （P<0.01）， p-JNK， and p-p38 MAPK in the ovarian tissues of rats were significantly decreased in the medium and high-dose BSZYP group （P<0.01）. The level of E₂ was increased in all-dose BSZYP groups （P<0.05， P<0.01）， and the level of P in the medium-dose BSZYP group was increased （P<0.05）. ConclusionBSZYP improved the serum sex hormones， restored the estrous cycle， reduced atretic follicle and vesiculation， and maintained luteal morphology and function of BN rats， so as to improve luteal function and treat luteal phase deficiency. The mechanism of BSZYP may be related to reduce the level of ovarian tissue apoptosis in BN rats by regulating MAPKs signaling pathway.

Objective: To analyze the short-time efficacy of empagliflozin in the treatment of glycogen storage disease type Ⅰb (GSD Ⅰb). Methods: In this prospective open-label single-arm study, the data of 4 patients were collected from the pediatric department in Peking Union Medical College Hospital from December 2020 to December 2022. All of them were diagnosed by gene sequencing and had neutropenia. These patients received empagliflozin treatment. Their clinical symptoms such as height and weight increase, abdominal pain, diarrhea, oral ulcer, infection times, and drug applications were recorded at 2 weeks, 1 month, 2 months, 3 months, 6 months, 9 months, 12 months, and 15 months after treatment to assess the therapeutic effect. The liquid chromatography-tandem mass spectrometry method was used to monitor the changes in 1, 5-anhydroglucitol (1, 5AG) concentration in plasma. At the same time, adverse reactions such as hypoglycemia and urinary tract infection were closely followed up and monitored. Results: The 4 patients with GSD Ⅰb were 15, 14, 4 and 14 years old, respectively at the beginning of empagliflozin treatment, and were followed up for 15, 15, 12 and 6 months, respectively. Maintenance dose range of empagliflozin was 0.24-0.39 mg/(kg·d). The frequency of diarrhea and abdominal pain decreased in cases 2, 3, and 4 at 1, 2 and 3 months of treatment, respectively. Their height and weight increased at different degrees.The absolute count of neutrophils increased from 0.84×10⁹, 0.50×10⁹, 0.48×10⁹, 0.48×10⁹/L to 1.48×10⁹, 3.04×10⁹, 1.10×10⁹, 0.73×10⁹/L, respectively. Granulocyte colony-stimulating factor was gradually reduced in 1 patients and stopped in 3 patient. Plasma 1, 5 AG levels in 2 children were significantly decreased after administration of empagliflozin (from 46.3 mg/L to 9.6 mg/L in case 2, and from 56.1 mg/L to 15.0 mg/L in case 3). All 4 patients had no adverse reactions such as hypoglycemia, abnormal liver or kidney function, or urinary system infection. Conclusion: In short-term observation, empagliflozin can improve the symptoms of GSD Ⅰb oral ulcers, abdominal pain, diarrhea, and recurrent infection, also can alleviate neutropenia and decrease 1, 5AG concentration in plasma, with favorable safety.

Objective: To analyze the current adherence to imatinib in patients with gastrointestinal stromal tumors (GIST) in China and its influencing factors. Methods: A cross-sectional survey was conducted. Study period: from October 1, 2020 to November 31, 2020. Study subjects: GIST patients taking imatinib who were diagnosed and treated in public tertiary level A general hospitals or oncology hospitals; those who had not been pathologically diagnosed, those who never received imatinib, or those who had taken imatinib in the past but stopped afterwards were excluded. The Questionnaire Star online surgery platform was used to design a questionnaire about the adherence to adjuvant imatinib therapy of Chinese GIST patients. The link of questionnaire was sent through WeChat. The questionnaire contained basic information of patients, medication status and Morisky Medication Adherence Scale. Results: A total of 2162 questionnaires from 31 provinces, autonomous regions, and municipalities were collected, of which 2005 were valid questionnaires, with an effective rate of 92.7%. The survey subjects included 1104 males and 901 females, with a median age of 56 (22-91) years old. Working status: 609 cases (30.4%) in the work unit, 729 cases (36.4%) of retirement, 667 cases of flexible employment or unemployment (33.3%). Education level: 477 cases (23.8%) with bachelor degree or above, 658 cases (32.8%) of high school, 782 cases (39.0%) of elementary or junior high school, 88 cases (4.4%) without education. Marital status: 1789 cases (89.2%) were married, 179 cases (8.9%) divorced or widowed, 37 cases (1.8%) unmarried. Two hundred and ninety-four patients (14.7%) had metastasis when they were first diagnosed, including 203 liver metastases, 52 peritoneal metastases, and 39 other metastases. One thousand eight hundred and sixty-nine patients underwent surgical treatment, of whom 1642 (81.9%) achieved complete resection. The median time of taking imatinib was 25 (1-200) months. Common adverse reactions of imatinib included 1701 cases (84.8%) of periorbital edema, 1031 cases (51.4%) of leukopenia, 948 cases (47.3%) of fatigue, 781 cases (39.0%) of nausea and vomiting, 709 cases (35.4%) of rash, and 670 cases (33.4%) of lower extremity edema. The score of the Morisky Medication Adherence Scale showed that 392 cases (19.6%) had poor adherence, 1023 cases (51.0%) had moderate adherence, and 590 cases (29.4%) had good adherence. Univariate analysis showed that gender, age, work status, economic income, residence, education level, marriage, the duration of taking medication and adverse reactions were associated with adherence to adjuvant imatinib therapy (all P<0.05). Multivariate analysis showed that female (OR=1.264, P=0.009), non-retirement (OR=1.454, P=0.001), monthly income ≤4000 yuan (OR=1.280, P=0.036), township residents (OR=1.332, P=0.005), unmarried or divorced or widowed (OR=1.362, P=0.026), the duration of imatinib medication >36 months (OR=1.478, P<0.001) and adverse reactions (OR=1.719, P=0.048) were independent risk factors for poor adherence to adjuvant imatinib. Among patients undergoing complete resection, 324 (19.7%) had poor adherence, 836 (50.9%) had moderate adherence, and 482 (29.4%) had good adherence. Meanwhile, 55 patients with good adherence (11.4%) developed recurrence after surgery, 121 patients with moderate adherence (14.5%) developed recurrence, 61 patients with poor adherence (18.8%) developed recurrence, and the difference was statistically significant (P=0.017). Conclusions: The adherence to adjuvant therapy with imatinib in Chinese GIST patients is relatively poor. Females, non-retirement, monthly income ≤4000 yuan, township residents, unmarried or divorced or widowed, the duration of imatinib medication >36 months, and adverse reactions are independently associated with poor adherence of GIST patients. Those with poor adherence have a higher risk of recurrence after surgery. Positive interventions based on the above risk factors are advocated to improve the prognosis of patients with GIST.
