Objective:To evaluate the status quo and influencing factors of hyperlipidemia management in patients with contracted family doctor service in the community.Method:The baseline data and blood lipid testing results of 752 hyperlipidemia patients (334 males and 418 females) with contracted family doctor service in Yuetan Community Health Service Center from November?2019 to May 2020 were collected. The hyperlipidemic patients were managed by family doctors based on atherosclerotic cardiovascular diseases(ASCVD) riks assessment. The ASCVD risk levels and low-density lipoprotein cholesterol (LDL-C) compliance rate of patients with different general data were compared, and the influencing factors of LDL-C control failure were analyzed by logistic regression.Results:The ASCVD risk assessment showed that among 752 patients there were 172 cases of low risk(22.87%), 167 cases of moderate risk(22.21%),352 cases of high risk(46.81%) and 61 cases of extremely high risk(8.11%). A significant difference was detected in sex,rate of smoking,incidence of overweight or obesity among patients with different ASCVD risk levels ( P<0.05).The overall control rate of LDL-C was 48.8% (367/752), that for low, moderate, high and extremely high risk patients were 83.73% (144/172), 53.89% (90/167), 34.38% (121/352) and 19.67%(12/61), respectively. A significant difference was detected in sex(female: 52.87%, 221/418),age(aged over 80: 58.82%, 110/187), rate of smoking (non-smoking:52.40%, 327/624) and medication compliance (good compliance:52.87%,221/418) between LDL-C control and uncontrol groups (χ2=6.323,11.816,19.022,25.274; P<0.05). Multiple logistic regression analysis revealed that male gender ( OR=1.800,95% CI:1.325-2.419), smoking ( OR=2.630,95% CI:1.726-4.007) and poor medication compliance ( OR= 2.179, 95% CI: 1.581-3.003) were independent risk factors for uncontrolled LDL-C levels. Conclusion:Patients with hyperlipidemia have a relatively high risk of cardiovascular diseases, and their blood lipids are not well controlled. The management of blood lipid should be enhanced in patients with chronic diseases, particularly for male patients with smoking and poor medication compliance.

The intra-tumor MTX concentration was measured in 12 patients with cerebral gliomas and 31 patients of malignant gliomas were treated with intracarotid infusion of papaverine and bis-chloroaitrosourea (BCNU). After intracarotid infusion of papaverine to open up the blood-brain-barrier (BBB), the MTX concentration within tumor tissues was 1854? 512ng/gram, which higher than that without papaverine infusion, which was 1020? 512ng/gram. The diagnosis was glioblastoma in 21 patients and anaplastic astrocytoma in 10. They received the infusion for a mean of 2.1 times with 250mg BCNU each. The mean survival time was 101.6? 32.7 weeks, with 104 weeks of median survival time. Fourteen were still living, including 11 glioblastoma and 3 anaplastic astrocytoma. Of those, four have lived over three years. We considered combination of papaverine and BCNU infusion for chemotherapy of malignant cerebral glioma is simple, safe and effective, so long as tumors were susceptible to the chemotherapeutic drugs.

Objective To investigate the distribution of ompA gnne in 15 Chinese reference standard strains belonging to 15 serogroups of Leptospira interrogate, and to express recombinant OmpA ( rOmpA ) and to identify immunogenicity and immunoprotection of rOmpA. Methods Genomic DNAs from different leptospiral strains were extracted by phenol-chloroform method. Entire ompA gene fragments from the strains were amplified by PCR and then sequenced after T-A cloning. A prokaryotic expression system of ompA gene from L. interrogans strain 56601 was constructed, and the expression and yield of rOmpA were determined by SOS-PAGE plus Bio-Rad Agarose Image Analyser. Rabbits were immunized with rOmpA for obtaining antiserum, and immunodiffusion test was used to measure the antiserum's titer. Western blot assay was performed to determine the immunoreaetivity of rOmpA with the antiserum against rOmpA and antiserum against whole cell of L. interrogans strain 56601, while mi-croscopic agglutination test (MAT) was applied to detect the cross agglutination to the 15 L. interrogans strains. A leptospire adhering cell model and a leptospire infecting guinea pigs model were used to determine the adhesion-bloc-king effect of rOmpA antiserum and immunoprotection of rOmpA. Results All the 15 L. interrogans strains, but not L. biflexa strain Patoe Ⅰ , had sequence conserved ompA genes. The yield of rOmpA was approximate 20% of the total bacterial proteins, rOmpA could induce rabbits to produce antibody and immunodiffusion titer of the anti-serum was 1:4. Both antisera against rOmpA and against whole cell of L. interrogans strain 56601 were able to pro-duce positive Western blot signs to rOmpA, and the former offered 1 : 20-1 : 320 MAT titers to the 15 L. interrogans strains. 1: 10-1:160 dilutions of rOmpA antiserum could efficiently block L. interrogans strain 56601 adhering to J774A. 1 cells, and 100 μg and 200 μg rOmpA displayed 50.0% and 75.0% immunoprotective rates in the infee-ted guinea pigs. Conclusion ompA gene only exists in genomes of different pathogenic L. interrogans serogroups. rOmpA has relatively stronger antigenicity, cross immunoreactivity and certain immunoprotection, implying that this recombinant protein may be used as a candidate antigen for developing universal genetic engineering vaccine of L. interrogans.

Partial nature of "promoting blood circulation and dieresis" of Salvia Miltiorrhizain was initially demonstrated by investigating the regulation effect of AQP2 expression in kidney of trauma blood stasis model rats with the Salvia Miltiorrhizain so as to provide guidance for its clinical deployment of administration. Random allocation was taken to averagely divide 30 SD rats into two groups: 10 rats in normal group and 20 rats in blood stasis syndrome group. Trauma blood stasis rat model was established by quantitatively beating. Then the rat model group was divided into model group and salvia group. After 7 days of treatment, the rat kidney AQP2 expression was detected, the content of urine AQP2 was compared and the damaged local muscle and kidney pathological changes were observed by immunohistochemical method and western blot method. Compared with that of the normal group, rats in model group had inflammatory cells infiltration, blood stasis and edema of the injured local muscles and up-regulated AQP2 expression, decreasing urinary output, and kidney tissues blood stasis and edema (P < 0.05). On the other hand, compared with that of the model group, those parameters of rats in salvia group were all decreasing except urine output (P < 0.05). Such result indicated that Salvia Miltiorrhiza can reduce trauma blood stasis rat content of urine AQP2 and down-regulated AQP2 expression in kidney tissue, so as to reduce the reabsorption of water by renal tubular and increase urine output. The promoting blood circulation effect of Salvia Miltiorrhizain can alleviate the degree of the damaged tissue edema and encourage urine drainage. This therapy is closely related to the effect of regulating AQP2 in kidney by salvia, so the purpose of this study by verifying "promoting blood circulation and diuresis" as the mechanism for the regulation effect of the salvia on AQP2 expression.

Objective To analyze the ultrasonic features of thyroid microcarcinoma (TMC) and the causes of misdiagnosis. Methods The ultrasonic features including shape, margin, echogenecity, microcalcification, vascularity and lymphadenopathy were analyzed retrospectively in 26 pathologically-proven TMC patients. Results In 26 cases, 11 cases were diagnosed correctly before operation (11/26, 42.31%), 12 cases were misdiagnosed (12/26, 46.15%) as adenoma or benign nodule, and 3 cases were missed diagnosed (3/26, 11.54%). Among the 23 cases detected on ultrasound, 21 cases were solid and hypoechoic (21/23, 91.30%);19 cases were ill-defined (19/23, 82.61%);12 cases were taller than wide in shape (12/23, 52.17%); 14 cases had microcalcification (14/23, 60.87%); 7 cases showed central or peripheral blood flow signals (7/23,30.43%) with arterial resistance index>0.70 in 3 lesions and<0.70 in 4 lesions. Conclusions Several ultrasonographic features are helpful in identiifcation of TMC, including hypo/iso-echogenecity, ill-deifned margin, taller-than-wide shape, microcalciifcation, arterial signals with high resistance index, and abnormal lymphadenopathy. Moreover, for cases with multiple lesions, to the potential co-existence of benign and malignant lesions should be considered.

Objective To investigate the echocardiographic features and clinical significance of prenatal diagnosis of total anomalous pulmonary venous connection (TAPVC). Methods Fetal echocardiographic images of 13 fetuses with TAPVC conifrmed by pathology or postnatal echocardiography were reviewed. Echocardiographic features and clinical signiifcance of prenatal diagnosis of TAPVC were summarized. Results Twelve fetuses with TAPVC were diagnosed prenatally by fetal echocardiography, including seven cases of supracardiac type, three cases of infracardiac type and two cases of intracardiac type. The common echocardiographic characteristics of 12 fetuses with TAPVC included slightly size discrepancy of left heart and right heart, large foramen ovale with increased shunting at the atrial level, increased distance between left atrium (LA) and descending aorta, absent insertions of pulmonary veins in the LA, presence of pulmonary venous conlfuence on the top of LA and dilatation of vessels where pulmonary venous conlfuence drained. One case was missed prenatally and intracardiac type TAPVC was diagnosed by postnatal echocardiography. Among the 13 cases, three were isolated and the other ten were all in association with other abnormalities. Conclusions There are fetal echocardiographic characteristics of TAPVC. Fetal echocardiography plays an important role in prenatal diagnosis of TAPVC.

OBJECTIVETo evaluate the clinical efficacy of combined internal-external therapy of TCM on children pneumonia. Adopting multi-center, randomized, controlled, double blinded principle, children with pneumonia were divided into 2 groups. Besides the basic treatment of western medicine, to the 406 children in the treated group internal administering of Chinese recipe prescribed according to syndrome differentiation and external applying of Fuxiong plaster were given additionally, while to the 411 children in the control group simulative placeboes were given for instead. The clinical efficacy of treatment on disease and syndrome, improvement of TCM syndrome and physical signs of lung between the two groups were compared after treatment.

RESULTSThe cured-markedly effective rate of treatment on disease and syndrome was 97.3%, 95.1% in the treated group and 89.8%, 86.6% in the control group, respectively, the differences of the two indexes between the two groups were significant (P < 0.05). The improvements on physical signs of lung, symptoms as cough, dyspnea and sputum expectorating in the treated group were significantly better than those in the control group (P < 0.05).

CONCLUSIONIt was showed that the combined internal-external TCM treatment, which could significantly enhance the clinical efficacy, is an effective therapy for children pneumonia.

TCM syndrome differentiation system (TCM-SDS) possesses a complex nonlinear characteristic, which determines the falt that the evaluation of TCM efficacy should not be simplified to a causal or linear relationship. Previous selected indexes and methods for evaluating curative effect of Child's pneumonia have their limitations. This paper mainly introduces several thoughts and methods formed in the exploratory researches, employing data mining technology in this field. We believe that efficacy evaluation research of Child's pneumonia on the basis of standardized study of TCM-SDS is a scientific work. Applying data mining method in processing enormous and multilayer information of TCM differentiation has strong advantages in screening evaluating indexes of Child's pneumonia. Meanwhile, some major concerning technical categorizations and implementing strategies for the research are also introduced.
