Objective To evaluate the effect of Orem intervention on the living quality and psychological state of elderly pa-tients with pulmonary tuberculosis.Methods Sixty-eight elderly patients with pulmonary tuberculosis were randomly divided into control group (n=31) and observation group (n=37).Orem intervention was applied in the observation group, while routine nurs-ing was used in the control group.The score of short-form-36 health survey (SF-36), self-rating depression scale (SDS), self-rating anxiety scale (SAS) and satisfaction were compared between the two groups.Results After the intervention, the SF-36 scores of observation group were significantly increased in 8 dimensions, compared with control group , with statistically significant differences (p<0.05).Compared with the control group, the SDS and SAS scores of the observation group were significantly de-creased statistically (p<0.05).The satisfaction rates of the control group and the observation group were respectively 77.4% (24/31) and 94.6% (35/37), with statistically significant differences (p<0.05).Conclusion Orem intervention can effectively im-prove the living quality and psychological state of elderly patients with pulmonary tuberculosis , worth clinical promotion.

OBJECTIVETo explore the impacts on the cognitive level of the children with mental retardation (MR) treated with JIN's three scalp needling therapy and the training for cognitive and perceptual disturbance so as to seek the more effective therapeutic method for the treatment of MR in children. Methods Sixty-six MR children were randomized into a head-point needle-retaining therapy + training group (group A) and a training after acupuncture group (group B). Seven cases and 12 cases were dropped in the two groups respectively. Twenty-six cases accomplished the treatment in the group A and 21 cases in the group B. In the group A, the points on the head were stimulated and the needles were retained (30 min after the general acupuncture, the needles on the body points were removed; and those on the head points were retained for 1 h, including Sishenzhen, Naosanzhen, Zhisanzhen and Niesanzhen). Simultaneously, the training for the cognitive perceptual disturbance was combined. In the group B, 1 h after needle retaining at the body points and head points, all the needles were removed; the training for the cognitive perceptual disturbance was followed. The treatment was given once a day, and the treatment for 3 months was required. Before and after treatment, the Wechsler intelligence scale for children (WISC) was used for evaluation and observation of verbal intelligence quotient (VIQ) , performance intelligence quotient (PIQ) and full-scale intelligence quotient (TFIQ) and score changes of 11 items such as information, picture vocabu; lary, arithmetic, picture generalization, comprehension, etc.

RESULTSAfter treatment, FIQ, VIQ and PIQ scores were different significantly as compared with those before treatment (all P<0. 01). In the group A, the results of picture vocabulary, animal egg laying, maze, block design and geometric figure were all improved significantly (all P<0. 05). In the group B, the results of information, comprehension, block design and geometric figure were all improved significantly (all P<0. 05). After treatment, concerning the value difference in FIQ and PIQ of the two groups; the changes in the group A were more significant (both P<0. 01). After treatment, the results of picture vocabulary and maze were improved significantly in the group A as compared with the group B (both P<. 01). The IQ categories changed apparently after treatment in the two groups, toward the higher level in tendency generally, but without significant difference (both P>0. 05).

CONCLUSIONThe simultaneous treatment with head point retaining of JIN's three needling therapy and the training for cognitive and perceptual disturbance obviously improves children patients' verbal comprehension, expression ability, hand-eye coordination ability, attention, logical reasoning ability and visual perception. The efficacy is better than that in the treatment of the training after acupuncture.

Objective To investigate the value of standardized ultrasound screening in diagnosis of fetal congenital heart disease (CHD) during the first trimester. Methods This study retrospectively analyzed the clinical data of 8 383 fetuses who received ultrasound screening during the first trimester in the Dongguan Maternal and Child Health Hospital from September 2015 to December 2016. Standardized ultrasound was performed to observe fetal heart position, apical direction, apical four-chamber view, three vessels and trachea view and the thickness of nuchal translucency (NT). Fetuses with thickened NT or fetal CHD observed during the first and second trimester were followed up. Pregnancy outcomes and the growth of newborns within one year after birth were recorded and analyzed. Pathological results after the termination of pregnancy were compared with the results of routine karyotyping and chromosome microarray analysis (CMA). Results (1) A total of 27 cases of fetal CHD were identified during the first trimester giving a detection rate of 0.32% (27/8 383). These included ten (37.0%) of single atrium and/or single ventricle, seven (25.9%) of endocardial cushion defect (including two complicated by persistent arterial trunk), three (11.1%) of hypoplastic right heart syndrome, three (11.1%) of interventricular septal defect, two (7.4%) of hypoplastic left heart syndrome, one (3.7%) of mirror-image dextrocardia and one (3.7%) of right atrial enlargement and severe tricuspid regurgitation. Nineteen out of the 27 cases had NT thickening (NT≥3.0 mm) and 17 of them had a cystic hygroma (NT≥6.0 mm). Among the 27 cases, 22 were terminated in the first trimester which autopsy results were consistent with ultrasound and the other five were rescreened during the second trimester. Thirteen out of the 27 cases received chorionic villus sampling, and seven of them were found to have chromosomal abnormalities by karyotyping and CMA, among whom one was microdeletion of 22q11. (2) Twenty-one cases of CHD were detected in the second-trimester ultrasound screening, including five initially identified in the first trimester. These cases included four (19.0%) of complex cardiac malformations (with three or more malformations), four (19.0%) of interventricular septal defect, three (14.3%) of dextroaortic arch, left subclavian artery vagus and 'U' shaped vascular ring, three (14.3%) of hypoplastic right heart syndrome (including one complicated by coronary artery-right ventricular fistula and one by interventricular septal defect), two (9.5%) of transposition of the great arteries, two (9.5%) of tetralogy of Fallot, one (4.8%) of hypoplastic left heart syndrome, one (4.8%) of Taussig-Bing anomaly and one (4.8%) of coarctation of the aorta. Among the 16 cases first identified in the second trimester, eight had NT thickening, including one with cystic hygroma. Among the 21 cases, two were lost to follow-up after being transferred to another hospital; four with negative results in karyotype analysis and CMA were delivered vaginally at term (37-40 gestational weeks) with 1-min Apgar scores of ten points and postpartum ultrasound of the baby was consistent with the second-trimester ultrasound screening; 15 were terminated and the autopsy confirmed those findings in the second-trimester ultrasound screening. Eleven out of the 21 cases received amniocentesis and five of them were found to be abnormal according to karyotype analysis and CMA, including one of microdeletion of 22q11. Conclusions Standardized first-trimester ultrasound screening is important and of great clinical value in the diagnosis of fetal CHD. Increased NT thickness could be a key indicator of fetal CHD and chromosomal abnormalities in early pregnancy. CMA may facilitate detecting the abnormality of genetic material in fetuses with normal chromosome karyotype.

Of the 154 lesions reported in enhanced CT and enhanced MRI for patients with small hepatocellular carcinoma, there were 7 lesions and 2 lesions misdiagnosed according to the postoperative histopathological examinations, respectively. Lesions misdiagnosed in one imaging examination method were correctly diagnosed in the other two imaging examination methods. The sensitivity, specificity, accuracy were 97.4%, 63.0%, 92.3% for contrast-enhanced ultrasound in the diagnosis of small hepatocellular carcinoma. The above indica-tors were 95.5%, 63.0%, 90.6% for enhanced CT and 98.7%, 63.0%, 93.4% for enhanced MRI in the diagnosis of small hepatocellular carcinoma. There was no significant difference in the sensitivity and accuracy among the 3 imaging examination methods ( Q=2.92, 0.00, 1.81, P>0.05). Conclusion:Contrast-enhanced ultrasound, enhanced CT and enhanced MRI all have good diagnostic value in diagnosis of small hepatocellular carcinoma, and they complement each other.

Objective:To study the binding characteristics of horse-derived P[12] rotavirus GST-VP8*-Horse P[12]E403 protein to oligosaccharides and saliva receptors, provides an important scientific basis for the cross-species transmission and the mechanism of interaction between the bodies.Methods:The E. coli expression system was used to express and purify the horse-derived P[12] rotavirus GST-VP8*-Horse P[12]E403 protein. The receptor binding characteristics of this genotype were analyzed by saliva and oligosaccharide binding experiments.
