Objective To analyse the prognosis and risk factors of lung cancer with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) in Tongchuan City, and to provide a theoretical basis for improving the prognosis of patients with lung cancer complicated with AECOPD. Methods A total of 280 patients with lung cancer combined with AECOPD admitted to Tongchuan People's Hospital from January 2021 to August 2022 were selected and divided into survival group and death group according to whether the patients survived during hospitalization. Serum carcinoembryonic antigen (CEA), cytokeratin 19 fragment (CYFRA 21-1) and other tumor markers were compared between the two groups. Lung function was measured by lung function instruments, and the levels of forced expiratory volume in one second (FEV1), forced vital capacity (FVC), FEV1/FVC and other lung function indicators were compared between the two groups. The patients' clinical data were collected from the medical record system, and univariate analysis and logistic regression were used to analyze the independent risk factors affecting the prognosis of patients with lung cancer complicated with AECOP. Results The values of FEV1, FVC and FEV1/FVC in the death group were significantly lower than those in the survival group (P<0.05). Serum CEA and CYFRA 21-1 levels in the death group were significantly higher than those in the survival group (P<0.05). Multiple logistic regression analysis showed that albumin level <35 g/L (OR=2.728), TNM stage III to IV (OR=2.416), multidrug-resistant bacterial infection (OR=2.982), and GOLD grade III to IV (OR=3.417) were independent risk factors for death in patients with lung cancer complicated with AECOPD in Tongchuan City (P<0.05). Conclusion Patients with lung cancer complicated with AECOPD in Tongchuan City have a high risk of death during hospitalization, especially patients with TNM stage III to IV and GOLD grade III to IV. Multi-drug resistant bacteria infection should be actively controlled to improve the albumin level of patients, which is conducive to the prognosis of patients.

OBJECTIVE To study the mechanism of interfering with long non-coding RNA nicotinamide nucleotide transhydrogenase-antisense RNA1 （LncRNA NNT-AS1） expressing to reduce paclitaxel （TAX） resistance in non-small cell lung cancer （NSCLC） cells. METHODS NSCLC TAX-resistant cell line （A549/TAX） was constructed， and the expressions of LncRNA NNT-AS1 in normal， parental， and drug-resistant cells were observed. The targeting relationship of microRNA-582-5p （miR-582- 5p） with LncRNA NNT-AS1 and high mobility group box2 （HMGB2） was verified. A549/TAX cells were cultured in vitro to observe the effects of interfering with LncRNA NNT-AS1 alone or interfering with LncRNA NNT-AS1 and miR-582-5p on the expressions of LncRNA NNT-AS1 and miR-582-5p， the mRNA and protein expressions of HMGB2， cell viability， clone formation and apoptosis. The effects of interfering with LncRNA NNT-AS1 on tumor growth and the expression of miR-582-5p and the mRNA and protein expressions of HMGB2 in tumor tissue were observed in nude mice. RESULTS Compared with normal cells， LncRNA NNT-AS1 was highly expressed in parental and drug-resistant cells （P＜0.05）， showing an increasing trend. It was validated that miR-582-5p had a targeting relationship with LncRNA NNT-AS1 and HMGB2. After interfering with the expression of LncRNA NNT-AS1， the expression of LncRNA NNT-AS1 and the mRNA and protein expressions of HMGB2， cell viability and the number of cloned cells in A549/TAX cell， decreased significantly， while the expression of miR-582-5p and the apoptotic rate increased significantly （P＜0.05）； simultaneously interfering with the expression of miR-582-5p could reverse above changes （P＜ 0.05）. Interfering with the expression of LncRNA NNT-AS1 in tumor cell could significantly reduce tumor volume and tumor weight of nude mice bearing tumors； at the same time， the expression of miR-582-5p was up-regulated significantly and the mRNA and protein expressions of HMGB2 were down-regulated significantly （P＜0.05）. CONCLUSIONS Interfering with the expression of LncRNA NNT-AS1 may alleviate TAX chemotherapy resistance in NSCLC through targeted up-regulation of miR-582-5p and down-regulation of HMGB2.

ABSTRACT OBJECTIVE：To study the effects of the extract of Xiongmatang on 5-HT and CGRP in brain tissue of rats with liver-yang hyperactivity and blood stagnation migraine. METHODS：Fifty male spontaneously hypertension （SHR） rats were randomly divided into model control group，Zhengtian pill positive control group （1.6 g/kg），the extract of Xiongmatang low-dose，medium-dose and high-dose groups（4.5，9.0，18.0 g/kg，by crude drug），with 10 rats in each group. Another 10 normal rats were taken as normal control group. Administration group was given relevant medicine intragastrically，once a day，for consecutive 28 d. Normal control group and model control group were given equal volume normal saline intragastrically. After last administration，except for normal control group，other groups were used to stimulate trigeminal ganglia（10 min）to establish liver-yang hyperactivity and blood stagnation migraine model，and maintained the administration once more after making the model. 30 min later，general behavior and tongue quality of rats were observed，and the blood pressure was measured；the contents of 5-HT and CGRP in cerebral tissue of rats were determined by ELISA. The protein expression of CGRP in cerebral tissue of rats were determined by Western blot method. RESULTS： Compared with the normal control group， the rats in the model control group had behavioral symptoms，such as the color of conjunctiva deepened and reddened， excessive hairdressing，head flicking，and most of the rats had purple tongue；the systolic pressure and the content and protein expression of CGRP were all increased obviously（P＜0.05 or P＜0.01）， while the content of 5-HT in cerebral tissue was decreased obviously（P＜0.01）. Compared with model control group，general behavior and tongue quality of rats were improved significantly in administration groups. Systolic pressure，the content and the protein expression of CGRP in cerebral tissue of rats were decreased significantly in Zhengtian pill positive control group and the extract of Xiongmatang high-dose group （P＜0.05），while the content of 5-HT in cerebral tissue of rats were increased significantly in Zhengtian pill positive control group，the extract of Xiongmatang medium-dose and high-dose groups（P＜0.05）.CONCLUSIONS：The extract of Xiongmatang has obvious protective effect on liver-yang hyperactivity and blood stagnation migraine model rats，the mechanism of which may be associated with reducing the content of CGRP in cerebral tissue and raising the content of 5-HT in cerebral tissue

OBJECTIVE: To screen for MYOC gene variants among sporadic patients with primary open angle glaucoma (POAG). METHODS: For 398 patients with POAG, Sanger sequencing was applied to detect potential variants of the MYOC gene. RESULTS: Eight patients (2.0%) were found to harbor variations of the MYOC gene. These included five types of variants, among which c.667C>T (p.Pro223Ser) and c.1138G>T (p.Asp380Tyr) were novel. c.382C>T (p.Arg128Trp), c.1109C>T(p.Pro370Leu) and c.1130C>A (p.Thr377Lys) were previously associated with POAG. Alignment of amino acid sequences of MYOC proteins of various species revealed that the two novel variants have occurred at highly conserved positions. c.1138G>T was predicted to be possible pathogenic by Bioinformatic analysis. CONCLUSION Two novel variants of the MYOC gene were detected among sporadic POAG patients, which enriched its variant spectrum.

OBJECTIVETo detect potential mutations of fibrillin-1 (FBN1) gene in a child with Marfan syndrome (MFS) and explore its molecular pathogenesis.

METHODSThe 66 exons of the FBN1 gene were analyzed by direct sequencing. SIFT and PolyPhen-2 were used to predict the structural and functional changes at the protein level.

RESULTSA novel heterozygous mutation c.3998 G>A (p.Cys1333Tyr) was found in exon 32 in the child. The same mutation was not found among his unaffected family members and 683 healthy controls. Multiple sequence alignment showed that this novel mutation was located in a highly conserved region of the FBN1 protein across various species and may induce structural change to a functional domain.

CONCLUSIONThe novel c.3998G>A (p.Cys1333Tyr) mutation of the FBN1 gene probably predisposed the MFS in the child. Above finding has enriched the spectrum of FBN1 mutations.
