OBJECTIVE: To estimate the univariate heritability of resting heart rate and common chronic disease such as hypertension, diabetes, and dyslipidemia based on extended pedigrees in Fujian Tulou area and to explore bivariate heritability to test for the genetic correlation between resting heart rate and other relative phenotypes. METHODS: The study was conducted in Tulou area of Nanjing County, Fujian Province from August 2015 to December 2017. The participants were residents with Zhang surname and their relatives from Taxia Village, Qujiang Village, and Nanou Village or residents with Chen surname and their relatives from Caoban Village, Tumei Village, and Beiling Village. The baseline survey recruited 1 563 family members from 452 extended pedigrees. The pedigree reconstruction was based on the family information registration and the genealogy booklet. Univariate and bivariate heritability was estimated using variance component models for continuous variables, and susceptibility-threshold model for binary variables. RESULTS: The pedigree reconstruction identified 1 seven-generation pedigree, 2 five-generation pedigrees, 23 four-generation pedigrees, 186 three-generation pedigrees, and 240 two-generation pedigrees. The mean age of the participants was 57.2 years and the males accounted for 39.4%. The prevalence of hypertension, diabetes, dyslipidemia in this population was 49.2%, 10.0%, and 45.2%, respectively. The univariate heritability estimation of resting heart rate, hypertension, and dyslipidemia was 0.263 (95%CI: 0.120－0.407), 0.404 (95%CI: 0.135－0.673), and 0.799 (95%CI: 0.590－1), respectively. The heritability of systolic blood pressure, diastolic blood pressure, fasting glucose, total cholesterol, triglyceride, high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol was 0.379, 0.306, 0.393, 0.452, 0.568, 0.852, and 0.387, respectively. In bivariate analysis, there were phenotypic correlations between resting heart rate with hypertension, diabetes, diastolic blood pressure, fasting glucose, and triglyceride. After taking resting heart rate into account, there were strong genetic correlations between resting heart rate with fasting glucose (genetic correlation 0.485, 95%CI: 0.120－1, P<0.05) and diabetes (genetic correlation 0.795, 95%CI: 0.181－0.788, P<0.05). CONCLUSION Resting heart rate was a heritable trait and correlated with several common chronic diseases and related traits. There was strong genetic correlation between resting heart rate with fasting glucose and diabetes, suggesting that they may share common genetic risk factors.

Objective: To analyze the prescriptions of analgesic drugs for the patients with cancer pain, and promote the rational use of narcotic and analgesic prescriptions. Methods: Using the PCNE classification system, the list of all drug-related problems (DRPs) from 115 patients admitted to the standardized treatment of cancer pain from January to December 2017 was analyzed. Re-sults: In our hospital from January to December 2017, there were 52 cases of prescribed DRPs for narcotic and analgesic drugs in the standardized treatment of cancer pain with the incidence of 45. 22% . DRPs mainly focused on treatment safety with the incidence of 72. 31% . The drug choice caused the highest incidence of DRPs accounting for 63. 24% , followed by dose selection accounting for 20. 59% . Conclusion: There are still unreasonable prescriptions of narcotic analgesia in our hospital. According to the PCNE classifi-cation system, it is necessary to strengthen the communication with clinicians, carry out education for the patients with cancer pain, and further educate pharmacy staff on the knowledge of analgesic drugs. Through the above measures, the regulation of prescription medication for narcotic analgesics can be intensified.

Objectives: To explore the clinical feathers and prognosis of primary malignant pericardial mesothelioma (PPM) reported in inland China. Methods: We searched Chinese data bases and collected medical records of PPM from 1981 to 2015 for patients' clinical, imaging, pathological, diagnostic and therapeutic information to explore the possible impact factors for prognosis. Results: A total of 186 patients were enrolled including 122 (65.6％) male, the mean age was (40.9±14.5) years at the range of (2-79) years. There were 108/166 (65.1％) patients suffered from dyspnea which was the most common symptom, 17 (10.2％) were complicated with cardiac tamponade and 48 (28.9％) complicated with constrictive pericarditis. 65 patients were misdiagnosed and 40 (61.5％) of them were diagnosed for tubercular pericarditis. 94 patients died and 30 (31.9％) of them died during hospitalization. 86 patients were discharged and received the follow-up study at the median of 6 months, 64 (74.4％) of them died. Multivariate Cox regression analysis did not find the meaningful clinical, imaging or pathological parameters to predict patients' mortality. Conclusion: PPM is a rare and highly aggressive pericardial malignant tumor, mainly involving middle-age males. Pathological combining immunohistochemical examinations are helpful for PPM diagnosis. Effective therapy has been lacking and comprehensive individualized therapy may improve the patients' prognosis.

Objective: To investigate the efficacy and safety of the recombinant human tumor necrosis factor receptor Ⅱ-IgG Fc fusion protein (rhTNFR: Fc, etanercept) for the treatment of occupational medicamentosa-like dermatitis induced by trichloroethylene (OMLDT) . Methods: In September 2011 to February 2016, 12 patients with OMLDT were treated with etanercept 25 mg, subcutaneous injection, twice per week, doubling of first dose. The course of treatment was 6 weeks. The drug eruption area and severity index (DASI) score, the proportion of patients achieving a 50%, 75% and 90% reduction in DASI (DASI50, DASI75, DASI90) and the serum level of TNF-α were used to assess the efficacy at different times. Adverse reactions were also recorded and evaluated. The results were statistically analyzed by nonparametric Friedman test and repetitive measurement ANOVA using the software SPSS19.0. Results: After 4 weeks treatment, the DASI score decreased form 56.33±7.02 to 0.50±0.91 (P<0.01) . The DASI50, DASI75 and DASI90 were all increased to 12 (100%) . The serum level of TNF-α decreased form (43.74±41.62) pg/ml to (3.03±0.47) pg/ml (P<0.01) . Statistically significant difference was observed from the above indexes. There were no adverse reactions in clinical application. Conclusion Recombinant human tumor necrosis factor receptor Ⅱ-IgG Fc fusion protein may be a safe and effective drug in the treatment of OMLDT.

This study aimed to examine the optimal conditions of laser-induced interstitial thermotherapy (LITT) via a single-needle delivery system, and the ablation-related pathological and ultrasonic changes. Ultrasound (US)-guided LITT (EchoLaser system) was performed at the output power of 2-4 Wattage (W) for 1-10 min in ex vivo bovine liver. Based on the results of the ex vivo study, the output power of 3 and 4 W with different durations was applied to in vivo rabbit livers (n=24), and VX2 tumors implanted in the hind limbs of rabbits (n=24). The ablation area was histologically determined by hematoxylin-eosin (HE) staining. Traditional US and contrast enhanced ultrasound (CEUS) were used to evaluate the treatment outcomes. The results showed: (1) In the bovine liver, ablation disruption was grossly seen, including a strip-like ablation crater, a carbonization zone anteriorly along the fiber tip, and a surrounding gray-white coagulation zone. The coagulation area, 1.2 cm in length and 1.0 cm in width, was formed in the bovine liver subjected to the ablation at 3 W for 5 min and 4 W for 4 min, and it extended slightly with the ablation time. (2) In the rabbit liver, after LITT at 3 W for 3 min and more, the coagulation area with length greater than or equal to 1.2 cm, and width greater than or equal to 1.0 cm, was found. Similar coagulation area was seen in the implanted VX2 carcinoma at 3 W for 5 min. (3) Gross examination of the liver and carcinoma showed three distinct regions: ablation crater/carbonization, coagulation and congestion distributed from the center outwards. (4) Microscopy revealed four zones after LITT, including ablation crater/carbonization, coagulation, edema and congestion from the center outwards. A large area with coagulative necrosis was observed around a vessel in the peripheral area with edema and hyperemia. (5) The size of coagulation was consistent well to the CEUS findings. It was concluded that EchoLaser system at low power can produce a coagulation area larger than 1.0 cm×1.0 cm during a short time period. The real-time US imaging can be used to effectively guide and assess the treatment.

H5 subtype avian influenza (AIV-H5) is a major causative agent of animalloimia a rapid and sensitive molecular biological diagnosis is crucial to the control program of AIV-H5. AIV-H5 real-time fluorescent reverse transcription loop-mediated isothermal amplification (qRT-LAMP) was established by means of heat treatment of the samples. The sensitivity, specificity and repeatability of this method were assessed and the performance of Calcein,SYBR Green I,HNB,SYTO 81 in colorimetric detection was comparatively analyzed to screen the optimum dye. The results showed the sensitivity of this method was 100 times higher than that of standard real-time fluorescent RT-PCR, and the detection limit was one copy of the gene per reaction. This method had no cross-reactivity with other common avian respiratory tract infectious disease-related pathogens such as IBV and NDV. The present study suggested Calcein was the optimum dye. Small-scale tests suggested this method was reliable for survey monitoring of AIV-H5 on the spot, indicating its potential applications in field investigation.

Objective To explore the effect of endotoxemia on triiodothyronine (T3) and thyroxine (T4),and the level and activity of iodothyronine deiodinase type 1 and type 3 mRNA.Methods Sixteen mice were randomly divided into control group and lipopolysaccharide (LPS) group,with 8 mice in each group.The mouse model of endotoxemia was replicated in the LPS group.In the both groups,blood samples from femoral week were collected to assay T3 and T4 levels,and the livers were sampled to inspect D1 and D3 mRNA levels and activities.Serum T3 and T4 levels were assayed with radioimmunoassay,D1 and D3 mRNA levels in liver were detected with real-time polymerase chain reaction,the activity of D1 and D3 in liver were measured by using ion-exchange chromatography combined with immunoassay.The data were statistically analyzed by SPSS 13.0 software.Results Statistical differences of T3,D1 and D3 mRNA levels and activities between the 2 groups were found (all P ＜0.01),while,there was no statistic difference in the statuses of T4 (P ＞ 0.05).Conclusions It is possible that euthyroid sick syndromes happens in endotoxemia episodes,and the changes of D1 and D3 mRNA levels and activities are the possible influencing factors.

OBJECTIVETo explore the association between parental genetic polymorphism of methylenetetrahydrofolate reductase (MTHFR) 677C/T and occurrence of nonsyndromic cleft lip with or without cleft palate (NSCL/P) in offspring in Shandong Province.

METHODSMTHFR genotypes were determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Parents of 89 NSCL/P patients treated at Qilu Hospital from August, 2006 to August, 2008 and those of 64 healthy children were recruited in this case-control study.

RESULTSFrequencies of T and C alleles in mothers of patients and healthy children were 65.73% and 46.09%, and 34.27% and 53.91%, respectively (Chi-square=13.663, P<0.01). Offspring whose mothers had T alleles were 2.243 times more likely to develop NSCL/P (95%CI: 1.408-3.572). Frequencies of T and C alleles in fathers of patients and healthy children were 62.92% and 55.47%, and 37.08% and 44.53%, respectively (Chi-square=2.222, P>0.05). The chance for parents of the patient and control groups to bear an affected fetus carrying homozygous mutations were 43% and 29%, respectively (P>0.05).

CONCLUSIONIn Shandong Province, maternal genotype for the MTHFR 677C/T polymorphism has a significant impact on the occurrence of NSCL/P in their offspring, whilst paternal genotype for this polymorphism may not be a risk factor for NSCL/P in their offspring.
