Abstract: Objective To understand the distribution and drug resistance of pathogenic bacteria of bloodstream infection in Fujian Province, and to provide reference for clinical rational drug use. Methods Bacteria identification and antimicrobial susceptibility test were carried out on the isolated strains of blood culture samples in 31 medical institutions in Fujian Province according to the unified plan. The data were statistically analyzed by WHONET 5.6 software according to the Clinical and Laboratory Standards Institute (CLSI) drug sensitivity executive standard in 2021. Results After removing the duplicate strains, 10 356 strains of bacteria were collected, including 3 668 strains of Gram-positive bacteria (35.4%) and 6 688 strains of Gram-negative bacteria (64.6%). The top 5 bacteria are Escherichia coli, Klebsiella pneumoniae, coagulase negative Staphylococcus, Staphylococcus aureus and Pseudomonas aeruginosa. In this study, the detection rate of methicillin-resistant Staphylococcus aureus (MRSA) was 24.5%, and the detection rate of methicillin-resistant coagulase-negative Staphylococcus aureus (MRCNS) was 76.8%. Vancomycin, teicoplanin and linezolid resistant staphylococci were not found. The detection rate of penicillin resistant Streptococcus pneumoniae was 3.2%. Vancomycin resistant Enterococcus faecalis and Enterococcus faecium were 0.8% and 1.1% respectively. The resistance rate of Escherichia coli to carbapenems was 0.8%, and the resistance rate to levofloxacin was 41.9%; the resistance rate of Klebsiella pneumoniae to carbapenems was 15.0%. The resistance rate of Acinetobacter baumannii to carbapenems was 45.1%; the detection rate of Pseudomonas aeruginosa was only 14.2%, and it maintained a high sensitivity to most drugs. Conclusions Most bloodstream infections in Fujian Province are caused by Escherichia coli, Klebsiella pneumoniae and Staphylococcus. The drug resistance of some strains is not optimistic, so we should continue to strengthen the clinical application management of antibiotics and use them correctly and reasonably.

AlM:To investigate the effects of pirfenidone ( PFD) on the proliferation and transfomring growth factor-β1 ( TGF-β1 ) expression in vitro culture rat corneal stromal cells.METHODS: Corneal stromal cells from 8 to 10wk SD rats were isolated, cultured and treated with different concentrations of PFD 0mg/mL (control group), 0. 15mg/mL (experimental group▏), 0. 3mg/mL (experimental group‖), 1mg/mL (experimental group Ⅲ) for 48h. CCK-8 assay was performed to assess cell proliferation, while immunocytochemistry and Western Blot were used to detect the expression of ki-67 and TGF-β1 expression, respectively. RESULTS: Compared with control group, PFD significantly inhibited the proliferation in a dose -dependent manner ( all P < 0. 05 ), so was protein expression of ki-67. PFD significantly down-regulated the expression of TGF-β1 in a dose-dependent manner (P<0. 05).CONCLUSlON: Pirfenidone can significantly inhibit the proliferation of rat corneal stromal cell by down regulating TGF-β1 expression, therefore, it has potential prospect in lightening the corneal wound healing reaction.

OBJECTIVETo observe the effect of Ganoderma lucidum decoction in treating Russula subnigricans poisoning (RSP) patients.

METHODSThe 14 patients of RSP in the treated group were treated with GLD (GLD, one dose was prepared by 100 g of Ganoderma lucidum decocted with water to 600 ml), on the base of conventional treatment, and 11 patients received conventional therapy in the previous year were taken as control. The clinical efficacy and parameters in them were compared, including the urine N-acetyl-D-glucosaminidase (NAG, which reflects the injury of kidney), the red blood cell and protein in urine, the alanine transaminase (ALT, which reflects the injury of liver), and the aspartate aminotransferase (AST, which reflects the injury of heart).

RESULTSA better clinical cure-markedly improving rate was showed in the treated group as compared with the control group, P < 0.01. In the treated group, red blood cell in urine disappeared after 24 hrs treatment in the majority of patients, urinary protein reduced obviously and the other three parameters reached the peak at the 3rd day then lowered gradually. In the control group, all the parameters increased continuously. Comparison between the parameters at corresponding time in the two groups showed significant difference (P < 0.01), those in the treated group were markedly lower than those in the control group respectively.

CONCLUSIONGLD has good effect in treating RSP, could obviously lower the fatat rate of RSP.

Methods In the 7 counties investigated of Xining in 2009, 5 towns were randomly selected in each county, and one school was randomly selected in each town, 80 children aged 8 to 10 were randomly selected in each school, and goiter were examined, urinary iodine and salt iodine were tested. Thyroid gland goiter of children was detected by thyroid palpation, children's urinary iodine was tested by As( Ⅲ )-Ce4+ catalytic spectrophotometry, and salt iodine was tested by direct titration. Results A total of 2919 children aged 8 to 10 were examined, 31 goiter was detected, goiter rate was 1.06%(31/2919).One thousand and seventy-eight urine samples were detected, urinary iodine median was 205.3 μg/L, that lower than 20 μg/L accounted for 1.9% (20/1078), lower than 50 μg/L accounted for 4.5%(48/1078). Two thousand and seventy-nine salt samples were detected, median of salt iodine was 32.80 mg/kg, the rate of non-iodized salt was 0.87%(18/2079), the coverage rate of iodized salt was 99.13%(2061/2079), the qualified rate of iodized salt was 98.64% (2033/2061), the consumption rate of qualified iodized salt was 97.79% (2033/2079). Conclusions Prevention and control of iodine deficiency disorders has achieved remarkable results in Xining city, all indicators have reached the national standard to eliminate iodine deficiency disorders.

OBJECTIVETo detect novel mutations in the fibrillin 1 (FBN1) and transforming growth factor beta receptor type II (TGFBR2) genes by screening the genes from 14 patients with Marfan syndrome.

METHODSDenaturing high performance liquid chromatography (DHPLC) was introduced to screen for FBN1 and TGFBR2 mutations exon-by-exon. The DNA amplification fragments which DHPLC elution profiles showed different from the corresponding normal elution profile were sequenced to identify the positions and types of mutations. Restriction fragment length polymorphism (RFLP) was employed to further prove the mutations when needed.

RESULTSTwo gene mutations of the FBN1 were found in the patients with Marfan syndrome. They were a novel substitutional mutation (Intron29 +4A > T) of FBN1 and a recurrent nonsense mutation (8080C >T) of FBN1.

CONCLUSIONIntron29 +4A > T and 8080C > T of FBN1 are possibly the pathogenesis of the MFS patients.

OBJECTIVETo study the protective effect of Chinese herbs for supplementing Shen to eliminate stone on renal injury induced by extracorporeal shockwave lithotripsy (ESWL) in patients with renal calculus.

METHODSSixty patients with diagnosis of renal calculus confirmed by X-ray film or CT combined with abdominal B ultrasonography but showing no obvious symptoms, were randomized into the treated group and the control group. They all were scheduled to receive ESWL treatment. To the patients in the treated group, prescribed Chinese herbs was orally administered in the three days before and after ESWL, patients in the control group ate and drank as usual. Changes of blood levels of nitric oxide (NO), endothelin-1 (ET-1), superoxide dismutase (SOD), malondialdehyde (MDA), tumor necrosis factor alpha (TNF-alpha), urinary levels of N-acetyl-D-glucosaminidase (NAG), gamma-glutamyltransferase (gamma-GT) and beta 2-microglobulin (beta 2-MG) before and after ESWL were observed.

RESULTSBlood levels of NO, ET-1, MDA and TNF-alpha significantly increased after ESWL in the control group, higher than the levels in the treated group (P < 0.05); and level of SOD decreased gradually in the control group reaching the valley 72 h after ESWL (P < 0.05), while in the treated group it was unchanged and remained at the level higher than that in the control group (P < 0.05). As for the urinary levels of NAG, gamma-GT and beta2-MG, after ESWL, they were all higher in the control group than those in the treated group, showing statistical significance (P <0. 05).

CONCLUSIONESWL could induce renal damage in patients with renal calculus and the Chinese herbs for supplementing Shen to eliminate stone can reduce the renal tubular damage by way of anti-oxidation and regulating the renal hemorrheologic disorder and the release of inflammatory mediators.

OBJECTIVETo study the clinical features of organic acidemia in neonates admitted to the intensive care unit.

METHODSThe clinical features of neonates from 15 neonatal intensive care units of Henan Province, who were diagnosed with congenital organic acidemia by gaschromatography-mass spectrometry (GC-MS) between June 2008 and August 2011 were retrospectively reviewed.

RESULTSFifty neonates of 287 high risk neonates were confirmed as having or highly suspected to have inborn errors of metabolism. Of the 50 cases, 32 cases were diagnosed with organic acidemia disease, including 28 cases of methylmalonic acidemia, 2 cases of propionic acidemia, 1 case of maple syrup urine disease and 1 case of isovaleric acldemla. In most cases, disease onset occurred in the first week after birth in most of cases (75%). Neonates whose symptoms occurred immediately after or within a few hours of birth presented with serious conditions. Clinical manifestations were various and mainly related to neurologic, respiratory and gastrointestinal symptoms such as poor response, coma, drowsiness, abnormal muscle tone, convulsions, polypnea, dyspnea, milk refusal, diarrhea and jaundice. Initial symptoms were non-specific and included dyspnea, poor response, milk refusal, lethargy and seizures.

CONCLUSIONSMethylmalonic acidemia is a common inherited metabolic disease in the neonatal period. Clinical manifestations of organic acid metabolism abnormalities in neonates are atypical and early onset is associated with more serious conditions.

We describe the case of a patient with severe hypertensive left ventricular hypertrophy and sustained hemodynamically unstable ventricular tachycardia (VT). Entrainment was demonstrated in the electrophysiological study. Activation mapping and pacemapping identified the location of the intramural reentrant VT with the exit site close to the epicardium. However, VT persisted after ablation at the epicardial exit site. Successful ablation was performed endocardially at the corresponding position.
