Adenocarcinoma presenting as a solitary mass with a cavity in chest computed tomogram is rare. A few reports have suggested an association between lung cancer and emphysema. We report a case of adenocarcinoma surrounding pulmonary emphysema that mimicked fungal pneumonia. This case highlights the need for cliniclians to be aware of the potential development of lung cancer in patients with emphysema.

Objective:To investigate the causes of secondary glaucoma after vitrectomy for familial vitreous amyloidosis associated with transthyretin (TTR) gene Gly83Arg mutation.Methods:A retrospective case study. From January 2008 to January 2020, 13 cases (23 eyes) with hereditary vitreous amyloidosis and treated by vitrectomy in the Affiliated Hospital of Zunyi Medical University were collected. Among them, there were 7 males with 12 eyes and 6 females with 11 eyes. The average age was 43.0±4.8 years. All the affected eyes underwent standard three-channel vitrectomy through the flat part of the ciliary body. According to whether complete vitreous detachment (PVD) was formed during the operation, it was divided into complete PVD group and incomplete PVD group; according to the occurrence time of secondary glaucoma and vitreous amyloidosis after surgery, it was divided into 1-12 months group and 13-36 months group, >37 months group. The average follow-up time after surgery was 36.7±6.0 months. The incidence of secondary glaucoma and the recurrence rate of vitreous amyloidosis between groups were compared by χ2 test; the correlation between recurrence of vitreous amyloidosis and secondary glaucoma after surgery was analyzed by Spearman rank correlation analysis. Results:Among the 23 eyes, there were 8 eyes in the complete PVD group and 15 eyes in the incomplete PVD group, respectively. Vitreous amyloidosis recurred in 15 eyes (65.22%, 15/23) after surgery. There were 14 (93.30%, 14/15) and 1 (6.70%, 1/15) eyes in the incomplete PVD group and the complete PVD group, respectively; the comparison of the recurrence rate of vitreous amyloidosis between the two groups was statistically significant ( χ2=11.676, P<0.01). 1-12 months group, 13-36 months group, >37 months group included 1 (4.35%, 1/23), 12 (52.17%, 12/23), 2 (8.70%, 2/23) Only eye. The recurrence rate in the 13-36 months group was significantly higher than that in the 1-12 months group and >37 month group. Secondary glaucoma occurred in 11 eyes (47.80%, 11/23) after surgery. 1-12 months group, 13-36 months group, above 37 months group were 1 (4.35%, 1/23), 8 (34.78%, 8/23), 2 (8.70%, 2/23) eyes. The incidence of secondary glaucoma in the 13-36 months group was higher than that in the 1-12 months group and >37 months group. Among 11 eyes with secondary glaucoma, 10 eyes had recurrence of vitreous amyloidosis after surgery, and 1 eye had no recurrence. The results of Spearman rank correlation analysis showed that there was a positive correlation between the recurrence of vitreous amyloidosis and the occurrence of secondary glaucoma ( rs=0.516, P=0.012). Conclusion:The incidence of secondary glaucoma after vitrectomy in a family with vitreous amyloidosis caused by the Gly83Arg mutation of TTR gene is higher, and its occurrence is significantly positively correlated with the recurrence of vitreous amyloidosis.

Objective This study aimed to investigate the potential relationship between urinary metals copper (Cu), arsenic (As), strontium (Sr), barium (Ba), iron (Fe), lead (Pb) and manganese (Mn) and grip strength. Methods We used linear regression models, quantile g-computation and Bayesian kernel machine regression (BKMR) to assess the relationship between metals and grip strength.Results In the multimetal linear regression, Cu (β=-2.119), As (β=-1.318), Sr (β=-2.480), Ba (β=0.781), Fe (β= 1.130) and Mn (β=-0.404) were significantly correlated with grip strength (P < 0.05). The results of the quantile g-computation showed that the risk of occurrence of grip strength reduction was -1.007 (95％ confidence interval:-1.362, -0.652; P < 0.001) when each quartile of the mixture of the seven metals was increased. Bayesian kernel function regression model analysis showed that mixtures of the seven metals had a negative overall effect on grip strength, with Cu, As and Sr being negatively associated with grip strength levels. In the total population, potential interactions were observed between As and Mn and between Cu and Mn (Pinteractions of 0.003 and 0.018, respectively).Conclusion In summary, this study suggests that combined exposure to metal mixtures is negatively associated with grip strength. Cu, Sr and As were negatively correlated with grip strength levels, and there were potential interactions between As and Mn and between Cu and Mn.

Soil microbes are the important indicator of soil quality. For exploring Chuanminshen violaceum planting to microbial effects in tobacco soil, this paper adopted Illumina MiSeq high-throughput sequencing to research the change of bacteria and fungi at the phylum and genus in the soil. The results showed that the Ch. violaceum planting increased the biodiversity of bacteria and fungi. The influence on fungi was greater than that on bacteria. It greatly increased the sequence of fungi, it obtained 32 978 16S rDNA and 32 229 18S rDNA sequence number. There was no change of the top three phylums in bacteria, but the content changed, Proteobacteria and Acidobacteria reduced by 1.73% and 1.4% respectively, and Actinobacteria increased by 0.65%. The advantage phylum Ascomycete in tobacco reduced by 27.99% to be second advantage phylum after Ch. violaceum planting, and the second advantage phylum Basidiomycete increased by 23.69% to become the first dominant fungi. At the genus, Ch. violaceum planting changed the order of dominant genus and the abundance was also changed. Some changed largely such as uncultured Acidobacteriaceae Subgroup-1, Gemmatimonas, Subgroup-2,uncultured Nitrosomonadaceae for bacteria, norank Sordariales, norank Agaricomycetes, Phialophora for fungi. Especially the rotation increased antagonistic microbes and physiological microbes and decreased pathogenic microbes. So the Ch. violaceum planting can improve the microbe community in tobacco soil.

OBJECTIVE: To explore the clinical therapeutic effect of light and heat of moxibustion for knee osteoarthritis (KOA). METHODS: A total of 216 patients with KOA were randomized into a traditional moxibustion group (72 cases, 8 cases dropped off), a moxibustion light group (72 cases, 9 cases dropped off) and a moxibustion heat group (72 cases, 10 cases dropped off).The special light-heat separation moxibustion cup was applied, the patients in the traditional moxibustion group received the treatment of moxibustion, the patients in the moxibustion light group received the treatment of moxibustion light and the patients in the moxibustion heat group received the treatment of moxibustion heat. The acupoint selection of the three groups was Neixiyan (EX-LE 4), Dubi (ST 35) and Zusanli (ST 36), the treatment was given 20 min each time, 3 times a week, 4 weeks were required totally, and the follow-up surveys were made 4 and 8 weeks after treatment. The scores of Western Ontario and McMaster University osteoarthritis index (WOMAC) and visual analogue scale (VAS) were observed before treatment, after 2 and 4 weeks of treatment, 4 and 8 weeks after treatment. The therapeutic effects were evaluated according to the criterion of patient global assessment (PGA) after 4 weeks of treatment and 8 weeks after treatment. RESULTS: Compared with before treatment, the pain scores, stiffness scores, physical function scores and total scores of WOMAC were reduced after 2, 4 weeks of treatment and 4 weeks after treatment in the three groups (<0.05). The pain scores, stiffness scores, physical function scores and total scores of WOMAC were reduced 8 weeks after treatment in the traditional moxibustion group and the moxibustion heat group (<0.05). The stiffness score, physical function score and total score of WOMAC were reduced 8 weeks after treatment in the moxibustion light group (<0.05). The pain score, physical function score and total score of WOMAC in the traditional moxibustion group after 4 weeks of treatment were lower than the moxibustion light group (<0.05). Compared with before treatment, the VAS scores were reduced after 2, 4 weeks of treatment and 4 , 8 weeks after treatment in the three groups (<0.05). The improvement rates in the traditional moxibustion group and the moxibustion heat group after 4 weeks of treatment and 8 weeks after treatment were superior to the moxibustion light group (<0.05). CONCLUSION The light and heat of moxibustion have therapeutic effect for KOA, and the therapeutic effect of moxibustion heat is superior to moxibustion light.

Objective: To evaluate the effect of transcutaneous electrical acupoint stimulation (TEAS) on the pregnancy outcomes of in vitro fertilization-embryo transfer (IVF-ET) based on the available clinical evidence. METHODS: We searched PubMed, MEDLINE, EMBASE, Cochrane Library, CNKI, VIP, CBM and Wanfang Database up to February 2021 for published randomized controlled trials (RCT) relevant to TEAS for the improvement of the pregnancy outcomes of IVF-ET. We performed literature screening, data extraction and quality evaluation according to the inclusion and exclusion criteria, followed by a meta-analysis with the RevMan 5.3 software. RESULTS: A total of 2 206 cases of IVF-ET from 9 RCTs were included, 1 018 in the TEAS group and 1 188 in the control. The clinical pregnancy rate was significantly higher in the TEAS than in the mock TEAS and non-TEAS control groups (RR = 1.85, 95% CI: 1.42－2.42, P < 0.001; RR = 1.23, 95% CI: 1.10－1.39, P = 0.0004), and so was it before and after oocyte retrieval (RR = 1.50, 95% CI: 1.03－2.17, P = 0.03; RR = 1.47, 95% CI: 1.12－1.92, P = 0.005). The TEAS group also showed dramatically improved embryo implantation rate (RR = 1.49, 95% CI: 1.24－1.79, P < 0.0001) and live birth rate (RR = 1.44, 95% CI: 1.04－1.98, P = 0.03) compared with the control. CONCLUSIONS As a safe and non-invasive treatment, TEAS can significantly improve the pregnancy outcomes of IVF-ET, with definite effectiveness. /.

The mammalian epididymis not only plays a fundamental role in the maturation of spermatozoa, but also provides protection against various stressors. The foremost among these is the threat posed by oxidative stress, which arises from an imbalance in reactive oxygen species and can elicit damage to cellular lipids, proteins, and nucleic acids. In mice, the risk of oxidative damage to spermatozoa is mitigated through the expression and secretion of glutathione peroxidase 5 (GPX5) as a major luminal scavenger in the proximal caput epididymidal segment. Accordingly, the loss of GPX5-mediated protection leads to impaired DNA integrity in the spermatozoa of aged Gpx5
