Objective: To analyze the effect of the use of antibiotics intervened by clinical pharmacist in diabetic ketoacidosis (DKA) patients. Method: This was a prospective clinical study with a historical control group.The group 1 was the control group which was not intervened for antibiotics use from January 2010 to November 2012. The group 2 was the intervention group treated from December 2012 to June 2016. Group 1 was divided into group 1a which included newly-onset diabetes patients and group 1b which included long standing diabetes patients. Group 2 was divided into the similar group 2a and group 2b.Clinical pharmacist supervised the implementation of terms to restrict the use of antibiotics.Changes of the rate of antibiotics use, the length of time of antibiotics use, hospital stay, the cost of antibiotics, etc.were compared. Result: In group 1a and group 2a, the rate of antibiotics use was 85%(107/126) and 31%(58/190)(χ²=25.787), the length of time of antibiotics use was 11(7-18)d and 6(4-10)d (U=1 507), the hospital stay was 23(18-27)and 20(6-24)d(U=8 177) , the cost of antibiotics was 1 615(1 000-2 970)and 1 080(504-1 932) yuan ( U=1 783), the differences had statistical significance(P<0.05). In group 1b and group 2b, the rate of antibiotics use was 97% (33/34) and 48% (23/48)(χ²=14.222), the length of time of antibiotics use was 8(6-12)d and 5(4-7)d (U=180), the hospital stay was 15(10-21)and 12(8-16)d (U=580), the cost of antibiotics was 2 200(1 356-3 100)and 1 600(705-2 200) yuan (U=223), the differences had statistical significance(P<0.05). Conclusion Clinical pharmacist intervened use of antibiotics was effective in reducing the use of antibiotics and financial burden.

PURPOSE: Choledochoduodenal fistula (CDF) is an extremely rare condition even in the most populous nations. However, diagnostic tools are inadequate for the young surgeon to be made aware of such a rare condition before surgery. Hence, basic understanding of the epidemiology, etiology, and management for this unusual but discoverable condition are necessary and essential. METHODS: The exclusive case reports of CDF, which were published from 1983 to 2014 concerning mainland Chinese people, were performed to review the epidemiology, etiology, and management. RESULTS: A total of 728 cases were incorporated into this review among 48 papers. More than half of the CDF cases were female (416) with an average age of 57.3 years. CDF was usually caused by cholelithiasis (573 of 728). Epigastric pain (589 of 728) and cholangitis (395 of 728) were the most common symptoms of CDF. CDF was usually detected and confirmed by endoscopic retrograde cholangiopancreatography (ERCP) (475 of 728) in Mainland China. The fistulas larger than 1 cm (82 of 654) were recommended for surgical biliary reconstruction. Fistulas between 0.5 cm and 1.0 cm (467 of 654) which were followed frequently by cholangitis attacks also required surgery; the rest were recommended to have stone removal and/or the application of an effective biliary drainage. Fistulas less than 0.5 cm (105 of 654) were usually received conservative therapy. CONCLUSION: CDF should be considered in differential diagnosis of recurrent epigastric pain and cholangitis. A possible ERCP should be arranged to investigate carefully. Depending on the size of fistula and clinical presentation, different programs for CDF are indicated, ranging from drug therapy to choledochojejunostomy.

OBJECTIVETo evaluate the replication and encapsidation of HBV mutants with the truncated C gene.

METHODSThe HBV mutants with the truncated C gene were constructed by molecular cloning and PCR-based deletion in vitro. The replication and encapsidation of HBV mutants were investigated by Southern blotting, PCR and real-time fluorescence PCR respectively after transfecting the HBV mutants plasmid into HepG2 cells by using liposome.

RESULTSThe C-truncated HBV mutant vectors were constructed successfully and confirmed exactly by clone sequencing and enzymes digestion. The C-truncated HBV mutants were replication defective, however, all types of HBV DNA could be detected positive in the cytoplasm and supernatant after co-transfecting the C-truncated HBV mutants plasmid and the helper constructs into HepG2 cells. The C-truncated HBV mutants were proved to produce 3-40 folds more progeny DNA than that of the wild-type HBV by DNA quantitative assay.

CONCLUSIONThe C-truncated HBV mutants are replication-deficient and could not replicate and encapsulate in the hepatocytes when transfected solely, however, the progeny HBV-variant viruses are encapsidated more effectively to secrete into supernatant when co-transfected with the helper construct which lacks part of 5 prime-proximal HBV RNA packaging signal Epsilon.

Objective To investigate the distribution of insulin resistance (HOMA-IR) index and its influencing factorsamong middle and old aged people with normal glucose and to provide the basis for early screening and prevention of type 2diabetes. Methods A total of 229 residents were selected with health records showed normal blood glucose (fasting bloodglucose < 7.0mmol/L, postprandial 2h blood glucose<11.1 mmol/L) and more than 40 years old from July, 2012 to June,2015. Height, weight, waist and hip circumference, and the fasting plasma glucose (FPG), insulin (FINS), lowdensity lipoprotein (LDL), uric acid, tumor necrosis factor (TNF) and interleukin -6 (IL-6) were recorded to analyzethe distribution of HOMA-IR and its influencing factors. Results Totally 229 people were included, of which 113 were male(49.34%), 116 female(50.66%) . The average age was(63.58 + 8.85) years old. The average HOMA-IR index was 0.94(1.08) and there were 21 people that HOMA-IR exceed the standard (HOMA-IR≥2.68), accounting for 9.17%.TheHOMA-IR index of different gender, age, waist circumference, hip circumference, uric acid in the elderly had significantdifference (P < 0.05) .Multiple linear regression analysis showed that HOMA-IR index was positively correlated withfemale, waist circumference and IL-6 and was negatively correlated with age. Conclusion The possibility of IR was higherin women with relatively low age, female, central obesity and high IL-6 levels among the middle and old aged people withnormal blood glucose.

Objective To improve vibration resistance of conventional blood transportation kits and mitigate hemolysis during transportation.Methods The structure of a blood transportation kit was modified.We installed a suspension brac-kets within the kit,added buffer material between the brackets,and tested the vibration-suppressing effect compared with the conventional blood transportation kit.Results Rubber and plastic materials between brackets were added,and double membrane suspension brackets were installed.After 4 and 6 min of vibration,free hemoglobin(FHb)[(1559.7 ±1038.5) and(1886.2 ±1023.8)mg/L],lactic dehydrogenase levels[(135.3 ±67.7)and(195.7 ±123.6)U/L]and hemolysis rate[(0.35 ±0.34)%and(0.42 ±0.38)%]in the conventional transportation kit were significantly higher than in the vibration-suppressing kit.K+did not change significantly,and was comparable in both groups at each time point.After 4 and 6 min of vibration, FHb in the conventional transportation kit exceeded the standard.However, after 12 min of vibration,FHb[(560.1 ±342.3)mg/L]in the vibration-suppressing kit were within the standard range.No bacterial growth was detected in either group.Conclusion The vibration-suppressing kit under research shows a better 1986vibration-suppressing effect,which could improve blood support capability in case of emergency.

OBJECTIVETo investigate gene mutations of the epidermal growth factor receptor (EGFR) and K-RAS in Chinese non-small cell lung cancers (NSCLCs).

METHODSMutations of exons 18, 19 and 21 of the EGFR and codons 12, 13 of the K-RAS in 101 NSCLCs were detected by PCR-amplifying and gene sequencing, and the relationship between mutations and clinical characters of NSCLCs and response to gefitinib were analyzed.

RESULTSOverall, 26 EGFR mutations (25.7%), 3 K-RAS mutations (2.9%) were detected, and EGFR mutation frequencies in adenocarcinomas, nonsmoker and female were found to be high (44.2%, 65.7% and 48.3% respectively). Nine out of 10 gefitinib treated patients with disease control was found with EGFR mutation.

CONCLUSIONThe data suggest that mutation frequency of EGFR in NSCLCs from Chinese patients is higher than that of western ethnicities, such mutations are well correlated with tumor response to gefitinib, and gefitinib is more fit for Chinese NSCLC patients.

Objective:To analyze the clinical and genetic features, as well as the treatment outcomes of two boys with nephrogenic syndrome of inappropriate antidiuresis (NSIAD) caused by gain-of-function mutations in the V2 vasopressin receptor gene (AVPR2).Methods:The clinical manifestations, genetic testing, therapeutic interventions and the outcomes of two boys with NSIAD hospitalized in the Department of Endocrinology, Beijing Children′s Hospital in April 2019 were reported. A literature search with "Nephrogenic syndrome of inappropriate antidiuresis" and "AVPR2 gene" as keywords was conducted at the China national knowledge infrastructure (CNKI), the Wanfang Data Knowledge Service Platform, PubMed and Springer Link up to May 2020. Relevant published articles were reviewed.Results:The two cases presented with chronic and severe hyponatremia with hypo-osmolality, inappropriately elevated urinary osmolality and urinary sodium levels. The onset age was 5.25-years and 2 months respectively. AVPR2 sequencing revealed a previously described hemizygous activating mutation (c.409C>T, p.R137C) in both of boys, each inherited the variant from their mother. Patient 1 limited fluid intake by himself in his daily life, intravenous and oral sodium supplementations showed no significant increase of serum sodium level. Oral furosemide increased the serum sodium level and maintained it within normal range. The serum sodium and potassium levels were in the normal range during the 1-year follow-up period with oral furosemide. The serum sodium level of Patient 2 increased with restricting fluid intake and with salt supplementation. However, after he experienced respiratory infection, the plasma sodium level decreased. Subsequently, oral anti-infection medicine and furosemide were applied. The serum sodium level increased two days later and remained at a normal range afterwards. The boy was 1 year old with normal growth. He stopped taking furosemide after 4 months while taking 1 gram of salt per day, the blood sodium level maintained at normal range. Literature search identified no reports in Chinese journals, whereas 50 publications were found in English journals. A total of 30 NSIAD probands were reported and 16 of those (53%) had childhood onset, most presented with seizures. The majority had a hotspot change at the nucleotide position of 409 in AVPR2. Nine cases had an amino acid change as R137C and five cases as R137L. Fluid restriction and oral urea intake were main treatment options, no report so far was found with oral furosemide treatment.Conclusions:NSIAD presented with hyponatremia without any other specific presentations. Genetic testing for variants in AVPR2 is helpful for early diagnosis and timely treatment. The first two cases of oral furosemide treatment were reported by the article which helped to maintain a normal serum sodium level after limiting fluid intake and supplementing sodium which showed limited effect.
