Objective To analyze the species of the antibody and immune responsibility in pneumonic plague patients in order to pave the way to screen the new sub-unit of the vaccine to provide the experimental basis. Methods Using the virulence-related protein microarray containing 149 proteins of Yersinia pestis (Y.pestis), the species of the antibody and immune responsibility were analyzed in serum of two pneumonic plague patients in six months after onset. Results Eighty-eight gene coded proteins were detected out the related antibodies except YPMT1.23c, YPMT1.86, YPO0406 and YPO1071 in patient 1. Forty-three antibodies from gene coded protein were analyzed, other forty-nine had not been identified in patient 2. Thirty-nine antibodies were detected in both patients. The proteins YPMT1.81c, YPMT1.84, YPCD1.31c, rw10, YPCD1.28, YPCD1.58, YPMT1.62c, YPO3247-related antibodies increased significantly by 109.96,176.4 ;20.64,17.73 ;16.50,7.16 ;23.51,7.65 ;46.00,25.61 ;4.50,8.24 ;5.98,5.08 ;23.98,4.76 folds, respectively. Conclusions The study on the antibody in pneumonic plague patients helps us to select the potential vaccine candidates, which reveals that eight proteins are the immunity diagnosis targets and the research key of sub-unit vaccine.

Objective To compare the difference of biochemical characteristics and virulent Pst Ⅰ of Yersinia pestis strains in traditional focuses of plague in Yunna Province and in the new focuses of plague in Yulong County. Methods The identification data of biochemical characteristics(Rhamnose, Glycerol, Maltose, L-Arabina and Melibiose fermentation) and virulence factor(Pst Ⅰ) from different focuses of plague in Yunna Province were Retrospectively collected by tube test followed by the analysis using statistics software SAS 8.0 by Fisher exact probability of disordered two-way R × C table χ2 test. Results Among 48 strains of Yersinia pestis from hantaan type plague focus, 1 strain fermented L-maltose, 48 strains fermented Glycerol. Among 165 strains of Yersinia pestis from the Soul type plague focus, 1 strain did not ferment L-maltose, only one of them fermented Glycerol. 1 strain from the Soul type plague focus was confirmed to have mutation, for the test of nitrate reduction reaction was negative. All 5 strains of Yersinia pestis from the new focuses of plague in Yulong County fermented L-maltose and Glycerol. The statistical result showed that the differences in L-maltose and Glycerol fermentation of Yersinia pestis from different natural focuses of plague in Yunnan Province were statistically siguificant (P < 0.01). The differences of other biochemical characteristics and Pst Ⅰ were not statistically significant (P > 0.01). Conclusions Biochemical characteristics of Yersinia pestis from the hantaan type plague focus and the Soul type plague focus in Yunnan province are overlapping. Biochemical characteristics of Yersinia pestis from the new focuses of plague in Yulong County are different from those tradition focuses of plague in Yunna Province but share similarities to those from Unquiculatus focuses in North Tibet.

To investigate the anti-hepatoma mechanism of α-pinene, HepG2 cell was treated with α-pinene and the change of cell cycle was examined by flow cytometry. The expression of miR-221, which was related the regulation of G₂/M phase, was detected by quantitative Real-time PCR. Meanwhile, TargetScan and other online bioinformatics methods were used to analyze and predict the target genes of miR-221, then the expression level of related target genes were detected by quantitative Real-time PCR. The results showed that α-pinene inhibited the proliferation of HepG2 cells in dose-dependent manner. It was also proved that HepG2 cells were arrested at G₂/M phase by α-pinene (P<0.05). The expression of miR-221 was down-regulated in α-pinene treated HepG2 cell. The bioinformatics analysis showed that CDKN1B/P27 and CDKN1C/P57 may be the protential targets of miR-221 and both of them were significantly up-regulated（P<0.001,P<0.05）by α-pinene treatment. According to these results, it was believed that α-pinene may inhibit the proliferation of hepatocellular carcinoma cells through arrest the cell at G₂/M phase, which may be associated with the down-regulate of the miR-221 expression and up-regulate of the CDKN1B/P27 and CDKN1C/P57 expression.

Objective: To study the clinicopathological characteristics of non-Hodgkin lymphoma (NHL) of the prostate. METHODS: We collected the clinical data on 6 cases of NHL of the prostate pathologically confirmed between 2001 and 2017. The patients were aged 49－76 (median 62) years old, with the main clinical manifestations of painless swelling of the prostate and lower urinary tract obstruction. We analyzed the clinical features and the results of histological detection, immunohistochemical staining and B-cell gene rearrangement assay, and explored the clinicopathological characteristics and differential diagnosis of the disease based on the relevant literature. RESULTS: Histological detection revealed diffuse large B-cell lymphoma (DLBCL) in 4 cases (66.7%), B-lymphoblastic lymphoma (B-LBL) in 1 (16.7%), and Burkitt lymphoma (BL) in another (16.7%). DLBCL was histologically characterized by diffuse oval or round medium-to-large-sized lyphoid cells with an infiltrative growth pattern, B-LBL by monotonous small-to-medium-sized lymphoid cells with prominet mitosis and apoptosis, and BL by diffuse and monotonous medium-sized neoplastic cells with round or oval nuclei, an infiltrative growth pattern, scanty cytoplasm and visible mitosis. One of the DLBCL patients received 5 doses of R-CHOP chemotherapy and has been followed up to the present time, while the other 3 were lost to follow-up; the B-LBL patient died at 1 month after diagnosis; and the BL patient gave up treatment. CONCLUSIONS Non-Hodgkin's lymphoma of the prostate mostly presents as diffuse large B-cell lymphoma, and its diagnosis depends on immunohistochemistry and related molecular detection as well as its clinical and histopathological manifestations.

Objective: To evaluate the auditory efficacy and subjective satisfaction of adhesive bone conduction hearing aid in children with unilateral congenital aural atresia (UCAA). Methods: Ten subjects (5 males and 5 females) diagnosed with UCAA with an average age of 8.3 years old (ranged from 5 to 15) were included in Beijing Tongren Hospital, Capital Medical University from January to August 2019. The free sound field hearing threshold, word recognition score in quiet, speech reception threshold in noise and sound localization ability (results were measured by RMS error) tests were performed in unaided and aided situation, respectively. Subjective satisfaction questionnaires were also distributed to subjects. Paired t test and Wilcoxon signed rank test were used as statistical analysis methods. Results: The average hearing threshold in aided condition was improved by (21.9±4.4) dB (t=15.8，P<0.05). Speech recognition abilities were generally improved both under quiet and noise (P<0.05);however, when the binaural summation, squelch and head shadow effects were analyzed respectively, the binaural squelch effect was not statistically improved (P>0.05), while the other effects were improved in aided condition (P<0.05). In sound localization test, there was no significant difference of the RMS error value between the unaided and aided situation (P>0.05). The subjects got high satisfaction rates in three subjective questionnaires. Conclusion: The adhesive bone conduction hearing aid can provide significant audiological benefit for children with UCAA as well as raising the quality of their life.

Numerous randomised controlled trials have suggested the positive effects of acupuncture on chronic obstructive pulmonary disease (COPD). However, the underlying therapeutic mechanisms of acupuncture for COPD have not been clearly summarized yet. Inflammation is central to the development of COPD. In this review, we elucidate the effects and underlying mechanisms of acupuncture from an anti-inflammatory perspective based on animal studies. Cigarette smoke combined with lipopolysaccharide is often used to establish animal models of COPD. Electroacupuncture can be an effective intervention to improve inflammation in COPD, and Feishu (BL13) and Zusanli (ST36) can be used as basic acupoints in COPD animal models. Different acupuncture types can regulate different types of inflammatory cytokines; meanwhile, different acupuncture types and acupoint options have similar effects on modulating the level of inflammatory cytokines. In particular, acupuncture exerts anti-inflammatory effects by inhibiting the release of inflammatory cells, inflammasomes and inflammatory cytokines. The main underlying mechanism through which acupuncture improves inflammation in COPD is the modulation of relevant signalling pathways: nuclear factor-κB (NF-κB) (e.g., myeloid differentiation primary response 88/NF-κB, toll-like receptor-4/NF-κB, silent information regulator transcript-1/NF-κB), mitogen-activated protein kinase signalling pathways (extracellular signal-regulated kinase 1/2, p38 and c-Jun NH2-terminal kinase), cholinergic anti-inflammatory pathway, and dopamine D2 receptor pathway. The current synthesis will be beneficial for further research on the effect of acupuncture on COPD inflammation.

The aim of this study was to investigate the regulatory effect of the total glycoside extracted from leaves of Rehmannia (TLR) and Dihuangye total glycoside capsule (DTG) on intestinal microflora in diabetic nephropathy rats. Forty-eight rats were randomly divided into the control group (C), model group (M), Huangkui capsule group (0.75 g·kg^-1·d^-1, HK), irbesartan group (27 mg·kg^-1·d^-1, YX), TLR low dose group (4.3 g·kg^-1·d^-1, DHYL), TLR high dose group (7.2 g·kg^-1·d^-1, DHYH), DTG low dose group (216 mg·kg^-1·d^-1, JNL), DTG high dose group (360 mg·kg^-1·d^-1, JNH). Rat model of diabetic nephropathy was induced by intraperitoneal injection of small dose of streptozotocin (45 mg·kg^-1, STZ) and feeding high-fat diet and 5% glucose drinking water. After oral administration for two weeks, the 16S rDNA sequencing method was used to study the effects of the TLR and DTG on intestinal flora in diabetic nephropathy rats. The results showed that compared with the control group, the intestinal flora of diabetic nephropathy rats had changed from phylum units to the genus units. Moreover, the proportion of lactobacilli in the intestinal bacteria of the model group was significantly decreased, and the proportion of lactobacilli in the administration group was increased, especially the YX group, TLR low dose group and DTG low dose group. The data suggest that the total glycosides of Rehmannia glutinosa improved the disorder of intestinal flora in STZ-induced diabetic nephropathy rats.
