ObjectiveTo analyze hospitalized death related factors in elderly patients with nonST-segment elevation myocardial infarction (NSTEMI). MethodsThree hundred and two patients (≥65 years old) with NSTEMI were included. Thirty-two patients of them died in hospital (death group). Their clinical data were retrospectively analyzed and correlated factors for in-hospital death were evaluated. ResultsCompared with survival group, patients in death group were more likely to have 3 or more chronic diseases,heart function killip grades Ⅲ- Ⅳ, heart rate> 100/min and peripheral blood WBC count>10X 10<'9>/L on admission (all P<:0.05). There was no significant difference in fasting plasma glucose level and serum creatinine on admission between the two groups (both P:>0.05). But after glomerular filtration rate(eGFR) were estimated by the modified abbreviated MDRD equations based on the Chinese CKD patients, patients in death group were more likely to be with renal dysfunction and pulmonary infection (both P<0.01 ). Multiple logistic regression analysis showed that heart function killip grades Ⅲ-Ⅳ, renal dysfunction evaluated by eGFR, pulmonary infection on admission were the independent predictors for in-hospital death in elderly patients with NSTEMI. ConclusionsCoexistence of 3 or more chronic diseases is a related factor of death and heart function killip grades Ⅲ-Ⅳ, renal dysfunction evaluated by eGFR and pulmonary infection are the independent predictors for in-hospital death in elderly patients with NSTEMI.

Objective To investigate the expression of regulators of G protein signaling(RGS), including RGS2, RGS3 and RGS4 in OLETF rats, as well as the effects of metformin on these expressions. Methods LETO rats were used as control group. Eight-week-old male OLETF rats were assigned to two guoups randomly:model and trial(metfomin dose during 8~(th) to 22~(nd) weeks:300mg kg~(-1)·d~(-1);during 23rd to 28th weeks:400 mg·kg~(-1) ·d~(-1))groups. Expressions of RGS mRNA in aorta and heart werequantified by real-time PCR. Results RGS2, RGS3 and RGS4 mRNA of the thoracic aorta and left ventricle were significantly higher in model group than in control group (P<0.01). Compared with model group, metformin significantly reduced their mRNA in trial group (P<0.01). Conclusions Upregulation of RGS2, RGS3 and RGS4 mRNA expression in the thoracic aorta and left ventricle of OLETF rats is in correlation with cardiovascular lesions; while downregulation of their expression is in correlation with the action of metformin.

OBJECTIVETo study the effect of Xiaotan Sanjie Recipe (XTSJD) and its mechanism on vasculogenic mimicry (VM) of human gastric cancer xenografts in nude mice.
METHODSThe tumor-bearing mice model was established by subcutaneous inoculating with xenografts of human gastric cancer into the right armpit of 30 BALB/c nude mice. After modeling, the tumor-bearing mice were randomly divided into the normal saline group, the XTSJD group, and the doxycycline hyclate (DH) group, 10 in each. And the mice were administered with corresponding medicine by gastrogavage for 4 weeks. Then all mice were killed by cervical dislocation. The tumor mass were weighed and the tumor inhibition rate calculated. The amount of VM in tumor was counted. Expressions of matrix metalloproteinase (MMP) -2 and MMP-9 were tested using immunohistochemical method.
RESULTSTumor weight in the XTSJD group and the OH group decreased significantly when compared with the NS group (P<0.01). The amount of VM in the XTSJD group (24.50+/-3.03) and the OH group (14.70+/-1.34) was significantly less than that in the NS group (33.10+/-2.64) (P<0.01). The positive expressions of MMP-2 and MMP-9 in the XTSJD group and the OH group was significantly lower than that in the NS group (P <0.01).
CONCLUSIONXTSJD could inhibit the formation of VM in xenografted tumor of nude mice. The mechanism might be correlated with the down-regulation of MMP-2 and MMP-9 expressions.

Abstract: Objective To compare the diagnostic efficacy of the upgraded version of the GeneXpert automated fluorescent quantitative PCR system (GeneXpert MTB/RIF Ultra, GeneXpert Ultra) and the original version of the GeneXpert system (GeneXpert MTB/RIF, Xpert), real-time fluorescent quantitative nucleic acid detection (FQ-PCR), real-time fluorescent thermostatic amplification of Mycobacterium tuberculosis RNA (SAT-RNA), real-time fluorescent thermostatic amplification detection of DNA (thermostatic amplification method) and traditional BACTEC MGIT 960 liquid culture (culture method) for special specimens of tuberculosis, in order to analyze its application value in clinical detection. Methods Using prospective research methods, a total of 170 special specimens (including 47 pleural and ascites effusion samples, and 34 24-hour urinary sediment specimens, 49 tissue specimens and 40 fester specimens) were collected i'an Chest Hospital from January to September 2021. GeneXpert Ultra, Xpert, FQ-PCR, SAT-RNA, isothermal amplification, and traditional culture were used for detection. Clinical diagnosis was used as the standard, and sensitivity, specificity, positive predictive value, negative predictive value, coincidence rate, and Kappa value were compared among the methods. Results The sensitivities of GeneXpert Ultra, Xpert, FQ-PCR, SAT-RNA, isothermal amplification, and traditional culture were 65.18% (73/112), 49.11% (55/112), 37.50% (42/112), 19.64% (22/112), 8.04% (9/112), and 22.32% (25/112), respectively. The sensitivity of GeneXpert Ultra was higher than that of the other five methods, and the differences were statistically significant (χ2=66.25, 42.10, 28.89, 13.09, 4.92, 15.18, all P<0.05). GeneXpert Ultra result analysis showed that: 5.48%(4/73) cases had trace, that is, trace Mycobacterium tuberculosis load, 79.45% (58/73) cases were extremely low, 10.96% (8/73) cases were low, 2.74% (2/73) were medium, , and 1.36% (1/73) were high load. In 4 trace samples, the Xpert detection was negative for all. Of the 73 GeneXpert Ultra positive reports, 63 were rifampicin-sensitive, 6 were rifampicin-resistant, and 4 were rifampicin-resistant but of unclear resistance. Of the 55 Xpert positive reports, 45 were rifampicin-sensitive, 2 were rifampicin-resistant, and 8 were rifampicinresistant but of unclear resistance.. Conclusions The new generation of GeneXpert MTB/RIF Ultra has high sensitivity, specificity and drug resistance detection rate, and its advantage is even more apparent in the pathogenic diagnosis of special
specimens of tuberculosis. It can be used as one of the preferred methods in samples with low bacterial load.

OBJECTIVETo evaluate the RT-PCR-ELISA method applied for testing live attenuated hepatitis A vaccine titer.
METHODSA solid phase hybridization-enzyme colorimetric detection method was used for detecting specific nucleic acid. Primer labeled with biotin was used to amplify viral gene fragment, then the product was quickly hybridized with the specific probe covalently coupled on DNA-binding microplate wells. Finally, peroxidase-labeled streptavidin was used in colorimetric detection. The results were judged by reading A value. Eleven batches of live attenuated hepatitis A vaccine titer were tested by this method. The results were compared with that of routine cell culture method (CCID50).
RESULTSThe sensitivity was similar to routine cell culture method (P>0.05). This method was convenient, fast and specific.
CONCLUSIONCCID50 method may be replaced by the RT-PCR-ELISA method in evaluating the titer of live attenuated hepatitis A vaccine.

UNLABELLEDOBJECTIVE; To evaluate the clinical value of different CT diagnostic criteria for peripancreatic artery and vein invasion in pancreatic carcinoma through comparison with the findings on surgical exploration.
METHODSOf 72 patients of having suspected pancreatic carcinoma were examined by multiplane spiral CT. Among 43 confirmed by surgical pathology; 15 underwent pancreaticoduodenectomy; 28 were found to have unresectable tumors. The peri-pancreatic major vessels including the superior mesenteric artery, celiac artery, hepatic artery, superior mesenteric vein and portal vein were explored carefully during surgical exploration.
RESULTSThe criteria for peri-pancreatic artery invasion was the presence of one of the following signs: artery embeded in tumor, or more than half of the artery circumference involved by tumor with wall irregularity or stenosis. The sensitivity of the above described criteria was 75.0% (12/16). If the criteria of tumor involvement exceeding half of the vessel circumference were adhered to, the sensitivity was 87.5% (14/16), which was high than the former, but the specificity was lower than that of the former one (90.2% versus 95.1%). The criteria for peri-pancreatic vein invasion was presence of any of the following signs: vein obliteration, more than half of the vein circumference involved by tumor, vein wall irregularity, vein stenosis, tear-drop sign of superior mesenteric artery. The sensitivity of the above described criteria was 92.9% (39/42), higher than that of the criteria that more than half of the vessel circumference was involved by the tumor (69.0%, 29/42), but the specificity of both criteria was the same (97.4%, 37/38).
CONCLUSIONFor assessing peri-pancreatic artery and vein invasion, using the combination of different CT diagnostic criteria has higher accuracy than when using only criteria of more than half of vessel circumference involved by tumor.
