OBJECTIVETo explore the relative factors on the failure in digit replantation in order to take preventions to control the risk factors.
METHODSFrom January 2013 to December 2013, 236 consecutive patients (311 fingers) underwent digit replantation were collected to analyze retrospectively, involving 183 males and 53 females with an average age of 34.5 years old ranging from 2 to 62 years old (6 cases under 6 years old and 230 cases elder than 6 years old). There were 51 thumbs, 87 index fingers, 78 middle fingers, 63 ring fings and 32 little thumbs. Forty cases(forty fings) who were failured as the observation group, the others as the control group. The factors of age, gender, finger, cause of injury, smoking history, ischemia duration, plane of division, condition of venous drainage and condition of arterial repair we assessed.
RESULTSAll 236 cases with 311 fingers were replanted, 40 fingers were failured after operation. The relative factors on the failure in digit replantation included smoking history, cause of injury, plane of division, condition of venous drainage and condition of arterial repair (P< 0.05). There were no significant correlation between the failure and age, gender, finger and ischemia duration (P>0.05).
CONCLUSIONSmoking history, causes of injury, plane of division, condition of venous drainage and condition of arterial repair are risks of failure in digit replantation. Before choosing the type of operation, it should be think about the patient's general conditions, injury status, grasp firmly the operative indications and actively carry out surgical treatment.

With the rapid development of multimedia teaching, this article is to declear the necessity of traditional blackboard in the teaching of medical genetics. Multimedia is not a versatile teaching model, and the weakness of the traditional teaching method are increasingly prominent. This article mainly discusses that how blackboard teaching effectively makes up for the deficiencies of multimedia teaching, from the four parts including the integrity of knowledge system, deductive teaching, teaching flexibility and the interaction between teacher and student. Therefore, the traditional blackboard teaching advantages and is very important in the teaching of medical genetics. The reasonable combination of the two teaching methods will sufficiently improve the effectiveness of classroom teaching.

OBJECTIVETo probe into the mechanism of electroacupuncture intervention for lipid metabolism of metabolic syndrome patients.
METHODSEighty cases of metabolic syndrome were randomly divided into an electroacupuncture combined with western medicine group (observation group) and a simple western medicine group (control group), 40 cases in each group. The observation group was treated with electroacupuncture at Back shu points, Zusanli (ST 36),Zhongwan (CV 12),Sanyinjiao (SP 6) etc. as main combined with oral administration of Simvastatin, Glipizide XL, and Felodipine sustained-release tablets for lipid-lowering, glucose-lowering and antihypertensive treatment; the control group was treated with oral administration of western medicine only (the medicine was the same with observation group). The Body Mass Index (BMI) and the blood lipid of the patients were detected respectively before and after treatment.
RESULTSThe BMI, Three Acids Glyceride (TG), Total Cholesterol(TC), Low Density Lipoprotein Cholesterol (LDL-C) and High Density Lipoprotein Cholesterol (HDL-C) were compared respectively before and after treatment, there were significant differences between them in observation group (all P < 0.01); while in control group, there were significant differences of TG,TC,LDL-C and HDL-C before and after treatment (all P < 0.01), and with no significant difference in BMI before and after treatment. There were significant differences of BMI,TG,TC,LDL-C and HDL-C between two groups after treatment (P < 0.01, P < 0.05).
CONCLUSIONThe electroacupuncture has an obvious effect to reduce body mass, and acupuncture combined with medication has a better effect of improving the lipid metabolism than simple medication.

The prokaryotic expression plasmid pQE30-HN of hemagglutinin-neuraminidase (HN) protein gene of bovine parainfluenza virus type 3 (BPIV3) strain HJ-1 was expressed by IPTG induction in E. coli XL1Blue. The recombinant HN protein(rHN) was purified by electroeluting method, and used as coated antigen. An indirect enzyme-linked immunosorbent assay (ELISA) was developed to detect the antibody valence of BPIV3. The best working conditions of ELISA were as follows: the antigen concentration was 6 microg/mL; the serum dilution was 1:50; the blocking reagent was 5% skimmed milk; the blocking time was 60 min at 37 degrees C; the second antibody concentration was 1:10 000; The cut-off value was 0.30. The method revealed a good specificity, no cross-reaction to the positive sera of BCV, IBRV or BRSV was observed. We applied the method to detect 323 serum samples of dairy cow in Heilongjiang Province, the seropositivity rate of BPIV3 was about 58%. The indirect ELISA established provided a technological basis for the development of ELISA kit.

Isotemporal substitution model is a powerful tool to explore the real association between physical behavior and health outcomes, which has the potential of the application in large-scale cohort study. This paper systematically introduces the principle of isotemporal substitution model and its implementation method in specific analysis to provide analytical ideas for the epidemiological research related to physical behavior in China. The baseline data of Regional Ethic Cohort Study in Northwest China conducted in Shaanxi province were used to analyze the relationship between physical behavior and cardiovascular disease with single-factor model, partition model and isotemporal substitution model. The advantages and disadvantages of different models were compared, and the advantages of isotemporal substitution model in quantifying physical activity health risk were introduced. Isotemporal substitution model could qualify physical behavior and health outcomes, which has wide application value in epidemiological research.

Objective To determine the hosts of hantavirus (HV) and its molecular epidemiological characteristics, to provide evidence for prevention and control on hemorrhagic fever with renal syndrome (HFRS). Methods Rodents were captured by a special trap within the residential area. The antigens of HV in lung tissues were detected by direct immuno-fluorescence assay (DFA). Nucleotide sequences of HV were amplified by RT-PCR with HV genotype-specific primer. The amplified genes were then sequenced. Phylogenetic tree were built on nucleotide sequence with Clusta1X 1.83 software. Results 1421 rodents were captured and classified into 8 species of 4 Genera in the epidemic area within 10 counties of Chuxiong prefecture, Yunnan province, between 2005 and 2006. Out of the 1421 rodents, 1056 (74.31%) of them were Rattus norvegicas and 280 (19.70%) belonged to Rattus flavipectus. The antigens of HV were detected by DFA in lung tissues and the total positive rate of HV was 5.15% (53/ 1029). After applying the sequencing nucleotide method to the 53 positive specimens, data showed that 21 specimens were positive and all of them belonged to Seoul type ( 15 samples were from Rattus norvegicus, 4 samples Rattasflavipectas, 2 samples Rattus nitidas). The partial S segments from 12 specimens were sequenced which appeared homologic with R22, L99 and HLD65 from GenBank in relatively high level (87.1%-99.7%). When compared to 76-118 strain of Hantaan type, their homologic degree was only 64.4%-69.1%. Results from Phylogenetic analysis showed that 12 specimens belonged to Seoul type. As for their homology, they were significantly similar to Seoul type and could be tentatively divided into two subtypes S1 and S3. Conclusion It was confirmed that the Seoul type virus, as HFRS' s pathogenetic agent mainly carried by rats, prevailed widely in Chuxiong prefecture. Owing to the local ecological environment, we also noticed the characteristics of different HV subtypes among Seoul type.

OBJECTIVE:
To investigate the incidence rate of infectious diseases during hospitalization in late preterm infants in Beijing, China, as well as the risk factors for infectious diseases and the effect of breastfeeding on the development of infectious diseases.
METHODS:
Related data were collected from the late preterm infants who were hospitalized in the neonatal wards of 25 hospitals in Beijing, China, from October 23, 2015 to October 30, 2017. According to the feeding pattern, they were divided into a breastfeeding group and a formula feeding group. The two groups were compared in terms of general status and incidence rate of infectious diseases. A multivariate logistic regression analysis was used to investigate the risk factors for infectious diseases.
RESULTS:
A total of 1 576 late preterm infants were enrolled, with 153 infants in the breastfeeding group and 1 423 in the formula feeding group. Of all infants, 484 (30.71%) experienced infectious diseases. The breastfeeding group had a significantly lower incidence rate of infectious diseases than the formula feeding group (22.88% vs 31.55%,
CONCLUSIONS
Breastfeeding can significantly reduce the incidence of infectious diseases and is a protective factor against infectious diseases in late preterm infants. Breastfeeding should therefore be actively promoted for late preterm infants during hospitalization.

OBJECTIVE:
To observe the clinical effect of acupuncture at "experienced ten acupoints" for postprandial distress syndrome.
METHODS:
A total of 62 patients with postprandial distress syndrome were randomly divided into an observation group (31 cases, 5 cases dropping off) and a control group (31 cases, 6 cases dropping off ). Acupuncture was applied at Baihui (GV 20), Zhongwan (CV 12), Qihai (CV 6), Tianshu (ST 25), Neiguan (PC 6), Zusanli (ST 36), Gongsun (SP 4), Danzhong (CV 17) in the observation group. In the control group, 6 non-acupoint points were intervened with shallow puncture. The treatment was given 20 min each time, once every other day, 3 times a week for a total of 4 weeks in the two groups. Symptom index of dyspepsia (SID) and Nepean dyspepsia index (NDI) scores were compared before and after treatment, and the efficacy was evaluated in the two groups.
RESULTS:
The effective rate in the observation group was 76.9% (20/26), which was higher than 28.0% in the control group (7/25, <0.01). After treatment, the SID and NDI scores in the two groups were lower than those before treatment (<0.01, <0.05), and the SID and NDI scores in the observation group were lower than those in the control group (<0.01, <0.05).
CONCLUSION
Acupuncture at "experienced ten acupoints" can significantly reduce the symptoms of dyspepsia and improve the quality of life in patients with postprandial distress syndrome.

Metabolic syndrome (MS) is a group of syndromes caused by the disorder of metabolism of various substances in the body. The main clinical manifestations are dyslipidemia, central obesity, hypertension, abnormal glucose tolerance and insulin resistance. With the changes of diet structure and habits, the incidence rate of MS is increasing, and the patients are younger. It is an important factor in many diseases, such as diabetes, atherosclerosis, coronary heart disease, hyperlipidemia, cirrhosis and some cancers. MS has seriously affected people's lives and health. Central obesity and insulin resistance are recognized as important pathogenic factors. At present, the pathogenesis of MS and its components has not been fully understood. The clinical manifestations of metabolic syndrome are complex and diverse. Traditional Chinese medicine (TCM) believes that the occurrence of metabolic syndrome is related to such factors as proper diet, emotional disorders, excessive escape and little movement, old age and physical deficiency. TCM scholars have studied the pathogenesis of MS in such pathological factors as phlegm and blood stasis, such visceral functions as liver, spleen and kidney, roles of Qi and blood, and emotional factors. As the basic substance of organism, Qi is closely related to the process of metabolism. The occurrence of MS is closely related to the rise and fall of Qi moving to and from the body as well as the abnormal gasification function of the transformation of Qi. Qi is derived from the five internal organs, which are respectively called Heart Qi, liver Qi, spleen Qi, lung Qi and kidney Qi. The "Qi of the five internal organs" is involved in the whole process of the generation, transportation and excretion of the essence of the body. Based on the "Qi of five internal organs", this paper discusses the pathogenesis of MS with phlegm, blood stasis and water drink as pathological factors.

Objective To assess the accuracy and reliability of the two 3D measuring methods, structured-light scanning and single-camera photogrammetry in forensic body surface damage and scar measurement. Methods The measuring results of 86 injuries by the ruler method, structured-light scanning and single-camera photogrammetry were compared and evaluated. The area measuring results of 13 simulated scars by the structured-light scanning, single-camera photogrammetry, Photoshop lasso pixel method and PDF reading software were compared and evaluated. The time consumed was recorded. The known specification information of the stickers was used as the standard value to compare the measuring accuracy of the ruler method, structural-light scanning and single-camera photogrammetry, and to calculate the root mean square error (RMSE). The consistency evaluation of intraclass correlation coefficient (ICC) for the repeatability of 3 measuring results obtained by different operators and the same operator. Results The differences in results of the two 3D measuring methods and the ruler method had no statistical significance; the differences between measuring results made by the structured-light scanning, single-camera photogrammetry and PDF reading software and that of the Photoshop lasso pixel method had no statistical significance. The post-processing of the single-camera photogrammetry consumed more time than that of other methods. When the long-distance group (10-40 cm) was measured, the results obtained by the ruler method were shorter than the standard value. The RMSE value results were structured-light scanning < single-camera photogrammetry < ruler method. The ICC value intragroup and intergroup were greater than 0.99. Conclusion Both structured-light scanning and single-camera photogrammetry can be applied in recording and measuring forensic body surface damage. The former has better performance in measurement accuracy and stability, while the latter has better color performance but longer post-processing time.
