Objective To determine the prevalence rate of elevated fasting plasma glucose(FPG)in residents of Liaoning Province and to identify the risk factors, which will help to effectively prevent/alleviate the occurrence and development of diabetes for reduction of socioeconomic burden. Methods A multi-stage stratified random cluster sampling method was used to investigate the residents of 3 towns and 3 rural areas in Liaoning Province. A total of 53 497 adults(aged 35-75 years)were surveyed by questionnaires and the risk or protective factors were analyzed by logistic regression method. Results The prevalence rate of elevated FPG was 24.7% with 23.2% in males and 26.0% in females, respectively. The results of multivariate logistic regression showed that age increase, female, high education, occupation(except farmers), alcohol drinking, obesity, hypertension, and dyslipidemia were risk factors of FPG(P < 0.05 or P < 0.001). Conclusion The prevalence of elevated FPG is high in the study population aged 35-75 years in Liaoning. It is necessary to strengthen the intervention in this part of the population in order to reduce the incidence of diabetes mellitus.

Objective:To investigate the effect of Relative Bedrest Condition Morita Therapy(RBCMT) on the improvement of depression and anxiety symptoms and personality in patients with recurrent depression disorder.Methods:Seventy patients with recurrent depressive disorder hospitalized in Kailuan Mental Health Center were randomly divided into study group and control group( n=35 in each group) from June to October, 2019.The study group was given RBCMT on the basis of conventional treatment and nursing.The Eysenck personality questionnaire (EPQ), Hamilton depression scale (HAMD) and Hamilton anxiety scale (HAMA) were used to assess the clinical symptoms and personality characteristics of the patients and to analyze and compare them. Results:(1) EPQ score in each dimension: There were significant differences within group among different time in introverted and extroverted dimension (study group: baseline: 46.14±10.99, the fifth weekend: 50.43±8.86, the eighth weekend: 53.86±7.08, F=6.291, P=0.003.Control group: baseline: 45.29±8.99, the fifth weekend: 48.29±8.31, the eighth weekend: 50.29±7.57, F=3.211, P=0.044) and neuroticism dimension score (study group: baseline: 60.14±5.49, the fifth weekend: 53.29±4.53, the eighth weekend: 50.57±4.33, F=36.809, P<0.001.Control group: baseline: 60.29±6.18, the fifth weekend: 55.86±6.00, the eighth weekend: 53.14±5.30, F=13.353, P<0.001) among different time points in the group.Neuroticism scores between the two groups at the same time were statistically significant(the fifth weekend: F=4.095, P=0.047, the eighth weekend: F=4.940, P=0.030). After 8 weeks of inclusion, there was a statistically significant difference between the two groups in the score of introverted and extroverted dimension ( F=4.157, P=0.045). There was no significant difference in the score of spiritual quality dimension at different time within the group or at the same time point between the groups.(2)HAMD score: There were statistically significant differences within group among different time(study group: baseline: 32.00±4.04, the fifth weekend: 15.23±5.01, the eighth weekend: 9.31±3.15, F=282.376, P<0.001.Control group: baseline: 31.91±4.59, the fifth weekend: 17.86±5.11, the eighth weekend: 11.17±3.64, F=195.019, P<0.001), and the differences between the two groups at the same time were statistically significant (the fifth weekend: F=4.724, P=0.033, the eighth weekend: F=5.205, P=0.026). (3)HAMA score: There were statistically significant differences within group among different time(study group: baseline: 18.69±8.87, the fifth weekend: 10.34±5.34, the eighth weekend: 7.97±2.98, F=28.679, P<0.001.Control group: baseline: 18.60±8.02, the fifth weekend: 13.31±6.35, the eighth weekend: 10.37±4.86, F=14.241, P<0.001). The difference between the two groups at the same time point was statistically significant (the fifth weekend: F=4.161, P=0.045, the eighth weekend: F=8.315, P=005). (4)Multiple linear regression results indicated that RBCMT ( β=-0.312, t=-2.360, P=0.022) and introverted and extroverted dimension personality ( β=-0.334, t=-2.355, P=0.022) were the influencing factors of HAMA. Conclusion:Compared with the conventional treatment, the Relative Bedrest Condition Morita Therapy can reduce the anxiety symptoms and improve the depressive symptoms by enhancing the extraversion personality characteristics of the patients.

OBJECTIVETo study the rotary angle and image features, so as to help early diagnosis.

METHODSFour adult cervical spine (C1-T1) specimens were used, including 2 males and 2 females,ranging in age from 28 to 40 years old. X-ray and CT examination were performed before the experiment. C2-C4 and C5-T1 were fixed respectively using self-made clamp. Unilateral locked facet of cervical spine was simulated under the violence of inflection and rotation, in which the muscle contraction was partially simulated, and at last the plain radiographs and CT of unilateral locked facet of cervical spine were analyzed.

RESULTSIn unilateral locked facet of cervical spine, the average rotary angle was 19.75 degrees, and average forward shift of vertebral was 3.68 mm. The intervertebral foramina below the injury plane were showed at 0 degrees,10 degrees, 180 degrees,190 degrees; the intervertebral foramina above the injury plane were showed at 150 degrees,160 degrees, 00 degrees, -10 degrees, and the facet was locked or in disorder at the injury plane. The intervertebral foramina at the anterior oblique position was bigger in interlocking side, but it was smaller in the opposite side. CT scan showed rotary spine, the naked facet sign; coronal plane reconstruction showed bilateral asymmetry; sagittal plane reconstruction obviously showed unilateral locked facet.

CONCLUSIONX-ray and CT both can independently diagnose unilateral locked facet of cervical spine. CT and three-dimensional reconstruction are more better than X-ray to diagnosing it.

OBJECTIVETo study the changes of expression of Survivin mRNA, BCRP mRNA and HER-2 mRNA in breast cancer after TE regimen neoadjuvant chemotherapy, and to find biological markers to predict the efficiency of TE regimen neoadjuvant chemotherapy.

METHODSThe gene expressions were detected by RT-PCR from 56 breast cancer patients before and after TE regimen neoadjuvant chemotherapy (docetaxel and epirubicin). The relationships between these gene expressions and chemotherapy responses were analyzed.

RESULTSThe overall response rate to neoadjuvant chemotherapy was 71.4%, including 8.9% (5/56) with complete response and 62.5% (35/56) with partial response. Pathological complete response was found in 4 cases (7.1%). Stable disease and progression of disease were 23.2% (13/56) and 5.4% (3/56), respectively. The expression of Survivin mRNA after neoadjuvant chemotherapy was 35.7% (20/56), significantly lower than 60.7% (34/56) before neoadjuvant chemotherapy (P = 0.008). The expression of BCRP mRNA after neoadjuvant chemotherapy was 19.6%, significantly lower than 37.5% before neoadjuvant chemotherapy (P = 0.036). The positive rate of HER-2 mRNA expression was 41.1% before the chemotherapy, and reduced to 21.4% after the chemotherapy (P = 0.025). The effective rates of the single positive expression of Survivin mRNA or BCRP mRNA were both lower than that of negative expression (P < 0.05). The level of HER-2 mRNA expression alone was not significantly associated with the effective rate of chemotherapy (P = 0.144). When the expression of all Survivin mRNA, BCRP mRNA and HER-2 mRNA were negative, the effective rate of neoadjuvant chemotherapy was higher than that in patients with positive expression (P = 0.003). The level of Survivin mRNA expression was not significantly associated with BCRP mRNA and HER-2 mRNA (P > 0.05).

CONCLUSIONThe expression of Survivin in combination with BCRP and HER-2 is associated with clinical response to TE neoadjuvant chemotherapy in breast cancer, and can be used as predictive biomarkers for chemosensitivity of TE regimen neoadjuvant chemotherapy for breast cancer.

AIM:To investigate the role of Krüppel-like factor 17(KLF17)in nude mouse xenograft model, and to explore the target genes regulated by KLF 17, the target gene functions and the signaling pathways involved.ME-THODS:The KLF17 was stably up-regulated in human lung adenocarcinoma A 549 cells and down-regulated in human lung adenocarcinoma H322 cells by lentiviral infection.BLAB/c nu/nu nude mice(n=11)were divided into KLF17 up-regual-tion group(n=5)and KLF17 down-regulation group(n=6).The right and left bodies of the nude mice were subcutane-ously injected with KLF17-up-/down-regulating cells and the counterpart empty vectors were used as control cells,respec-tively.The effects of KLF17 on the growth of the cell-derived xenografts in nude mice were analyzed.The mRNA and pro-tein expression levels of KLF17 in xenograft tumor tissues were analyzed by real-time PCR and immunohistochemical stai-ning,respectively.Transcriptome sequencing was used to explore the differentially expressed genes in the xenograft tumors derived from KLF17-up-regulating A549 cells,and the functions of the potential target genes were analyzed using the lung adenocarcinoma data from The Cancer Genome Atlas(TCGA)database.Gene Ontology and KEGG PATHWAY enrichment analyses were performed to analyze the functions of the differentially expressed genes and the involved signal pathways.RE-SULTS:The growth rate of KLF17-up-regulating A549 cell-derived xenograft tumors in the nude mice was significantly lower than that in empty control group(P<0.05),while the growth rate and the weight of KLF 17-down-regulating H322 cell-derived xenograft tumors in nude mice were significantly higher than those in empty control group(P<0.01 and P<0.05,respectively).In the A549 cell-derived xenograft tumor model,the KLF17 mRNA and protein were significantly in-creased in KLF17 up-regualtion group.The transcriptome sequencing showed the potential target genes regulated by KLF 17 were ras homolog family member V(RHOV)and coronin 1C(CORO1C).Ten-year cumulative survival time of the patients with lung adenocarcinoma from TCGA database was significantly different between high and low expression of RHOV and CORO1C at mRNA level.Increased expression levels of RHOV and CORO1C were correlated with short survival time in the patients with lung adnocarcinoma.The results of Gene Ontology and KEGG PATHWAY enrichment analyses indicated that the target genes(differentially expressed genes)regulated by KLF17 were related to the stimulation response,growth and adhesion of tumor cells,and participated in chemotaxis-,adhesion-and extracellular matrix receptor-related signaling path-ways.CONCLUSION:KLF17 inhibits the xenograft tumor growth in nude mice,and inhibits the oncogenes such as RHOV and CORO1C.The target genes regulated by KLF17 participate in the regulation of tumor adhesion-and growth-related sig-naling pathways.

OBJECTIVETo investigate the changes in the numbers of blood vessels and mast cells, which is relative to blood microcirculation in skin, during Qingpeng plaster (ZANG medicine) being applied to the skin surface of nude mice.

METHODFifteen healthy adult nude mice were divided into Qingpeng plaster group and the control group. The sites of skin tissues stuck with the plaster or with control plaster were selected after 7 days treated, and then all the slices stained and observed.

RESULTThe numbers of the vessels and the mast cells increased in the dermal tissue of Qingpeng paster group. Although there were a few dilated blood vessels in the control group, but the numbers of the vessels and the mast cells were obviously less than those of the Qingpeng plaster group. Statistical analysis showed that there was a significant difference (P < 0.001) between tow groups.

CONCLUSIONQingpeng plaster can cause obvious vascular dilatation and promot mast cells aggregation in the Qingpeng plaster stuck parts of the skin tissue.

OBJECTIVETo investigate the findings of contrast-enhanced multislice computed tomography (MSCT) that characterize intraductal papillary neoplasms of bile ducts (IPNB).

METHODSThe MSCT findings and clinical data of 16 cases of IPNB proven by surgical pathology were reviewed retrospectively.

RESULTSAmong the 16 cases, nine were adenoma (multi-lesions, n = 5; single lesions, n = 4) and seven were adenocarcinoma (multi-lesions, n = 4; single lesions, n = 3). Among the nine adenoma cases, seven showed nodules or masses in the expanding intrahepatic bile ducts with asymmetrical low density on plain scan, and two showed obvious expansion of biliary ducts and the inner wall of bile ducts was rough. All seven of the adenocarcinoma cases showed nodules or masses in the expanding intrahepatic bile ducts with asymmetrical low density-like adenoma. When contrast enhancement was applied, the nine adenoma cases manifested slight-to-moderate degrees of asymmetrical enhancement. For the seven adenocarcinoma cases, two showed asymmetrical enhancement similar to that of the adenoma cases and five showed continued enhancement; one case showed malignant infiltration of the bile duct and evident damage in the adjacent hepatic tissue. The CT plain scan findings for the two groups (adenoma and adenocarcinoma) were not significantly different (t = -1.17, P = 0.2632). Significantly different findings were obtained with the MSCT imaging analysis for the arterial phase (t = 6.53, P less than 0.01) and the portal vein phase (t = 5.63, P less than 0.01). All cases showed asymmetrical expansion of intrahepatic biliary ducts, diffuse or local, and four cases showed moderate expansion of the common bile duct. One adenocarcinoma case showed intumescence in the celiac lymph node by moderate asymmetrical enhancement.

CONCLUSIONMSCT is helpful for the differential diagnosis of IPNB from other hepatic lesions.

OBJECTIVETo compare therapeutic effects of electrical acupuncture (EA) at Qiuxu (GB 40) and Tianshu (ST 25), and to probe the factors of influencing the therapeutic effect.

METHODSTwo hundred and seventy-five cases were randomly divided into the test group of 138 cases treated with EA at Qiuxu (GB 40) and the control group of 137 cases treated with EA at Tianshu (ST 25). Their therapeutic effects were observed and the factors influencing the therapeutic effect were analyzed.

RESULTSThe transient effective rate was 70.3% in the test group and 58.4% in the control group with a significant difference between the two groups (P<0.05), and there were very significant differences between the two groups in the therapeutic effects at treatment of 4 weeks, and following-up 3 and 6 months later (P<0.001), the transient analgesic effect of EA at Qiuxu (GB 40) being better. EA had better transient effect on migraine for the mental workers, or the patient with high pain score at treatment, or more frequent attack. The long-term analgesic effect of EA at Qiuxu (GB 40) was better than Tianshu (ST 25).

CONCLUSIONThe analgesic effect of EA at Qiuxu (GB 40) is better than Tianshu (ST 25) and the profession and conditions of the patient are the factors influencing the therapeutic effect.
